ABSTRACT
Although a great deal of research has been done on sepsis in children,its pathogenesis remains controversial and unresolved,one of which is immune dysfunction.Immunosuppression is the core part of immune dysfunction,and it is related to the disease progression,treatment options,and prognosis changes in patients with sepsis.Since T lymphocytes play a crucial role in immune function,they have been regarded as an important indicator for judging changes in immune function in clinical practice.This review explained the mechanism of immunosuppression caused by some T lymphocyte subsets and its clinical application value in the evaluation,prognosis and immune intervention of sepsis.
ABSTRACT
ObjectiveTo explore the risk factors and survival analysis of chemotherapy compliance in ≥65 years old patients with non-small cell lung cancer. MethodsFrom December 2018 to August 2020, 110 patients with non-small cell lung cancer ≥65 years old in our hospital were selected for study. According to their chemotherapy compliance, the patients were divided into untreated (25 cases), partial chemotherapy (30 cases) and full chemotherapy (55 cases). Multivariate Cox regression was used to analyze the independent risk factors affecting the compliance of chemotherapy among the three groups, and constructed a column chart prediction model and evaluated the diagnostic effectiveness of the model using receiver operating characteristic (ROC) curves, calibration curves, and clinical decision curves. The patients were followed up until August 2023. Kaplan-Meyer survival curve and Log-rank test were used to compare the differences in survival time between the groups. ResultsThere were significant differences among the three groups in gender, long-term smoking history, education level, Charlson complication index, toxic and side effects of chemotherapy drugs and dosage, pathological type, operation mode, place of residence, payment mode, chemotherapy stage, white blood cell count and neutrophils (P<0.05). Multivariate Cox analysis showed that patients' education level, pathological TNM stage, toxic and side effects of chemotherapy drugs and dosage, operation mode, residence, payment mode and chemotherapy stage were independent risk factors affecting chemotherapy compliance of patients with non-small cell lung cancer (all P<0.05). There were significant differences in the survival rates between the non-chemotherapy group and the full chemotherapy group, and between the partial chemotherapy group and the full chemotherapy group (P<0.05), but there was no significant difference between the non-chemotherapy group and the partial chemotherapy group (P>0.05). And based on this, a prediction model was constructed, and the ROC curve was drawn to show that the AUC of the model was 0.758 (95%CI: 0.743‒0.855), the sensitivity was 0.788, and the specificity was 0.853, indicating that the model had high discrimination, the calibration curve indicated that the prediction model had good accuracy, the clinical decision curve indicated that the predictive model had strong clinical practicality. ConclusionNSCLC tends to occur in the elderly. We should focus on the patients with low educational level, late pathological TNM stage, severe toxicity and side effects, high dose of chemotherapy drugs, having undergone open chest surgery, living in rural areas, without medical insurance, and in the period of chemotherapy consolidation and refractory relapse, so as to improve their compliance with chemotherapy.
ABSTRACT
Objective:To explore the prognostic value of the serum concentration of human soluble stromelysin-2(sST2)combined with ultrasonic left ventricular diastolic function parameters for elderly patients with septic shock.Methods:This prospective study involved 150 elderly patients with septic shock admitted to the intensive care unit(ICU)of the First Hospital of Jiaxing between May 2019 and May 2022.Data on the following parameters were recorded on days 1, 3, 5, and 7 in the ICU: sST2 concentration, mitral early-diastolic inflow peak velocity(E), mitral late-diastolic inflow peak velocity(A), E/A ratio, early diastolic mitral annular velocity(e'), and E/e' ratio.According to the 28-day prognostic outcome obtained during follow-up, patients were divided into a survival group and a death group to compare differences in values of the above parameters between the two groups and at different time points.Logistic regression was used to analyze independent risk factors for 28-day mortality.The receiver operating characteristic(ROC)curve was used to analyze the predictive value for 28-day mortality, and further risk stratification was performed according to optimal cut-off values to compare differences in 28-day mortality under different risk stratification methods.The Kaplan-Meier survival curve was used to compare 28-day cumulative survival under different risk stratification methods and analyze the predictive value of the combination of the parameters for 28-day mortality.Results:On day 5 following ICU admission, e' was lower and E/e' and sST2 were higher in the death group than in the survival group.Univariate and multivariate Logistic regression analysis suggested that sST2(odds ratio: 1.010, P<0.001)was an independent risk factor for 28-day mortality in elderly patients with septic shock.sST2 had a sensitivity of 50.2%, a specificity of 79.1%, and an area under the curve of 0.660 for predicting 28-day mortality in patients with septic shock.The sST2 concentration was 89.3 μg/L on day 5 after ICU admission, which was the clinical cutoff point for predicting 28-day mortality.Based on the risk stratification of sST2 levels, the 28-day mortality rate was higher in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group.Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate was significantly lower in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group(44.0% vs.66.7%, log-rank test: χ2=9.101, P=0.003).The receiver operating characteristic curve showed that the combination of sST2, e', and E/e' significantly improved the prediction efficiency of 28-day mortality in elderly patients with septic shock, with an area under the curve of 0.844, a sensitivity of 89.7%, and a specificity of 66.5%. Conclusions:sST2 is an independent risk factor for 28-day mortality in elderly patients with septic shock.When combined with e' and E/e', sST2 can more accurately evaluate the survival prognosis of these patients.
ABSTRACT
Objective: To characterize the incidence density of systematic lupus erythematosus (SLE) in Yinzhou District of Ningbo from 2016 to 2021, and compare the age and gender specific differences. Methods: A retrospective cohort study was conducted based on the related data from 2015 to 2021 collected from the Health Information Platform of Yinzhou. Suspected SLE cases in local residents were identified by fuzzy matching of International Classification of Diseases 10th edition code "M32" or Chinese text "lupus". The classification criteria from Systemic Lupus International Collaboration Clinics-2012 and The European League Against Rheumatism/American College of Rheumatology-2019 were used for case verification. SLE cases were identified with specific algorithm based on verification results, and new cases were identified with 1 year as the washout period. The incidence density and 95%CI were estimated by Poisson distribution. Results: From 2016 to 2021, a total of 1 551 921 permanent residents were registered in Yinzhou, in whom 51.52% were women. The M(Q1,Q3) age at enrollment was 40.38 (27.54, 53.54) years. The M(Q1,Q3) of follow-up person-years was 3.83 (0.41, 5.83) years. There were 451 new SLE cases, in which 352 were women (78.05%). The 6-year incidence density was 8.14/100 000 person-years (95%CI: 7.41/100 000 person-years-8.93/100 000 person-years) for the total population, 3.68/100 000 person-years (95%CI: 2.99/100 000 person-years-4.48/100 000 person-years) for men and 12.37/100 000 person-years (95%CI: 11.11/100 000 person-years- 13.73/100 000 person-years) for women. The incidence density in men appeared a small peak at 20-29 years old, and began to increase with age from 40 years old. The incidence density in women was highest in age group 20-29 years (16.57/100 000 person-years) and remained to be high until 30-79 years old. The incidence density of SLE in Yinzhou show no significant temporal trend from 2016 to 2021 (men: P=0.848; women: P=1.000). Conclusions: The incidence density of SLE in Yinzhou from 2016 to 2021 was similar to those of other areas in China. SLE has a high incidence in women, especially in the young and elderly, suggesting that more attention should be paid to the diagnosis and treatment of SLE in women.

Objective: To construct a cervical cancer risk prediction model based on nested case-control study design and Yinzhou Health Information Platform in Ningbo, and provide reliable reference for self-risk assessment of cervical cancer in local women. Methods: In local women aged 25-75 years old who had no history of cervical cancer registered in Yinzhou before October 31, 2018, a follow up was conducted for at least three years, the patients who developed cervical cancer during the follow up period were selected as the case group and matched with a control group at a ratio of 1∶10. The prediction indicators before the onset was used in model construction. Variables were selected by Lasso-logistic regression, the variables with non-zero β were selected to fit the logistic regression model and Bootstrap was used for internal validation. The discrimination of the model was evaluated by area under the receiver operating characteristic curve(AUROC), and the calibration was evaluated by calibration curve and Hosmer-Lemeshow test. Results: The prediction indicators included in the final model were age, smoking status, history of cervicitis, history of adenomyosis, HPV testing, and thinprep cytologic test. The AUROC calculated in the internal validation was 0.740 (95%CI:0.739-0.740), and the calibration curve was almost identical with the ideal curve, P=0.991 in Hosmer-Lemeshow test, indicating that the model discrimination and calibration were good. Conclusions: In this study, a simple and practical cervical cancer risk prediction model was developed. The model can be used in general population with strong interpretability, good discrimination and calibration in internal validation, which can provide a reference for women to assess their risk of cervical cancer.
ABSTRACT
OBJECTIVE@#To compare the expected population impact of benefit and risk of aspirin treatment strategies for the primary prevention of cardiovascular diseases recommended by different guidelines in the Chinese Electronic Health Records Research in Yinzhou (CHERRY) study.@*METHODS@#A decision-analytic Markov model was used to simulate and compare different strategies of aspirin treatment, including: Strategy ①: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk, recommended by the 2020 Chinese Guideline on the Primary Prevention of Cardiovascular Diseases; Strategy ②: Aspirin treatment for Chinese adults aged 40-59 years with a high 10-year cardiovascular risk, recommended by the 2022 United States Preventive Services Task Force Recommendation Statement on Aspirin Use to Prevent Cardiovascular Disease; Strategy ③: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk and blood pressure well-controlled (< 150/90 mmHg), recommended by the 2019 Guideline on the Assessment and Management of Cardio-vascular Risk in China. The high 10-year cardiovascular risk was defined as the 10-year predicted risk over 10% based on the 2019 World Health Organization non-laboratory model. The Markov model simulated different strategies for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Quality-adjusted life year (QALY) and the number needed to treat (NNT) for each ischemic event (including myocardial infarction and ischemic stroke) were calculated to assess the effectiveness of the different strategies. The number needed to harm (NNH) for each bleeding event (including hemorrhagic stroke and gastrointestinal bleeding) was calculated to assess the safety. The NNT for each net benefit (i.e., the difference of the number of ischemic events could be prevented and the number of bleeding events would be added) was also calculated. One-way sensitivity analysis on the uncertainty of the incidence rate of cardiovascular diseases and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.@*RESULTS@#A total of 212 153 Chinese adults, were included in this study. The number of people who were recommended for aspirin treatment Strategies ①-③ was 34 235, 2 813, and 25 111, respectively. The Strategy ③ could gain the most QALY of 403 [95% uncertainty interval (UI): 222-511] years. Compared with Strategy ①, Strategy ③ had similar efficiency but better safety, with the extra NNT of 4 (95%UI: 3-4) and NNH of 39 (95%UI: 19-132). The NNT per net benefit was 131 (95%UI: 102-239) for Strategy ①, 256 (95%UI: 181-737) for Strategy ②, and 132 (95%UI: 104-232) for Strategy ③, making Strategy ③ the most favorable option with a better QALY and safety, along with similar efficiency in terms of net benefit. The results were consistent in the sensitivity analyses.@*CONCLUSION@#The aspirin treatment strategies recommended by the updated guidelines on the primary prevention of cardiovascular diseases showed a net benefit for high-risk Chinese adults from developed areas. However, to balance effectiveness and safety, aspirin is suggested to be used for primary prevention of cardiovascular diseases with consideration for blood pressure control, resulting in better intervention efficiency.

OBJECTIVE@#To explore and summarize the clinical characteristics and treatment of aggressive NK-cell leukemia (ANKL), and provide new insights for clinical diagnosis and treatment of this disease.@*METHODS@#The clinical data of 7 patients with ANKL admitted to the First Affiliated Hospital of Wannan Medical College from March 2014 to July 2021 were retrospectively analyzed, and their clinical characteristics, laboratory and imaging results, treatment and outcomes were analyzed.@*RESULTS@#Among the 7 patients, 5 were males and 2 were females, with a median age of 47 (33-69) years old. The morphology of bone marrow cells in 7 patients showed similar large granular lymphocytes. Immunophenotyping revealed abnormal NK cells in 5 cases. By the end of follow-up, 6 cases died and 1 case survived, with a median survival time of 76.9 (4-347) days.@*CONCLUSION@#ANKL is a rare disease with short course and poor prognosis. If combined with hemophagocytic syndrome (HPS), the prognosis is even worse. There is no unified treatment method at present, and the use of PD-1 inhibitors may prolong the survival in some patients.

Females increase aggression for mating opportunities and for acquiring reproductive resources. Although the close relationship between female aggression and mating status is widely appreciated, whether and how female aggression is regulated by mating-related cues remains poorly understood. Here we report an interesting observation that Drosophila virgin females initiate high-frequency attacks toward mated females. We identify 11-cis-vaccenyl acetate (cVA), a male-derived pheromone transferred to females during mating, which promotes virgin female aggression. We subsequently reveal a cVA-responsive neural circuit consisting of four orders of neurons, including Or67d, DA1, aSP-g, and pC1 neurons, that mediate cVA-induced virgin female aggression. We also determine that aSP-g neurons release acetylcholine (ACh) to excite pC1 neurons via the nicotinic ACh receptor nAChRα7. Together, beyond revealing cVA as a mating-related inducer of virgin female aggression, our results identify a neural circuit linking the chemosensory perception of mating-related cues to aggressive behavior in Drosophila females.

Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.
ABSTRACT
OBJECTIVE@#To evaluate the effect of curcumin on renal mitochondrial oxidative stress, nuclear factor-κB/NOD-like receptor protein 3 (NF-κB/NLRP3) inflammatory body signaling pathway and tissue cell injury in rats with acute respiratory distress syndrome (ARDS).@*METHODS@#A total of 24 specific pathogen free (SPF)-grade healthy male Sprague-Dawley (SD) rats were randomly divided into control group, ARDS model group, and low-dose and high-dose curcumin groups, with 6 rats in each group. The ARDS rat model was reproduced by intratracheal administration of lipopolysaccharide (LPS) at 4 mg/kg via aerosol inhalation. The control group was given 2 mL/kg of normal saline. The low-dose and high-dose curcumin groups were administered 100 mg/kg or 200 mg/kg curcumin by gavage 24 hours after model reproduction, once a day. The control group and ARDS model group were given an equivalent amount of normal saline. After 7 days, blood samples were collected from the inferior vena cava, and the levels of neutrophil gelatinase-associated lipocalin (NGAL) in serum were determined by enzyme-linked immunosorbent assay (ELISA). The rats were sacrificed, and kidney tissues were collected. Reactive oxygen species (ROS) levels were determined by ELISA, superoxide dismutase (SOD) activity was detected using the xanthine oxidase method, and malondialdehyde (MDA) levels were determined by colorimetric method. The protein expressions of hypoxia-inducible factor-1α (HIF-1α), caspase-3, NF-κB p65, and Toll-like receptor 4 (TLR4) were detected by Western blotting. The mRNA expressions of HIF-1α, NLRP3, and interleukin-1β (IL-1β) were detected by reverse transcription-polymerase chain reaction (RT-PCR). Renal cell apoptosis was detected by TdT-mediated dUTP nick end labeling (TUNEL). The morphological changes in renal tubular epithelial cells and mitochondria were observed under a transmission electron microscope.@*RESULTS@#Compared with the control group, the ARDS model group exhibited kidney oxidative stress and inflammatory response, significantly elevated serum levels of kidney injury biomarker NGAL, activated NF-κB/NLRP3 inflammasome signaling pathway, increased kidney tissue cell apoptosis rate, and renal tubular epithelial cell damage and mitochondrial integrity destruction under transmission electron microscopy, indicating successful induction of kidney injury. Following curcumin intervention, the injury to renal tubular epithelial cells and mitochondria in the rats was significantly mitigated, along with a noticeable reduction in oxidative stress, inhibition of the NF-κB/NLRP3 inflammasome signaling pathway, and a significant decrease in kidney tissue cell apoptosis rate, demonstrating a certain dose-dependency. Compared with the ARDS model group, the high-dose curcumin group exhibited significantly reduced serum NGAL levels and kidney tissue MDA and ROS levels [NGAL (μg/L): 13.8±1.7 vs. 29.6±2.7, MDA (nmol/g): 115±18 vs. 300±47, ROS (kU/L): 75±19 vs. 260±15, all P < 0.05], significantly down-regulated protein expressions of HIF-1α, caspase-3, NF-κB p65, and TLR4 in the kidney tissue [HIF-1α protein (HIF-1α/β-actin): 0.515±0.064 vs. 0.888±0.055, caspase-3 protein (caspase-3/β-actin): 0.549±0.105 vs. 0.958±0.054, NF-κB p65 protein (NF-κB p65/β-actin): 0.428±0.166 vs. 0.900±0.059, TLR4 protein (TLR4/β-actin): 0.683±0.048 vs. 1.093±0.097, all P < 0.05], and significantly down-regulated mRNA expressions of HIF-1α, NLRP3, and IL-1β [HIF-1α mRNA (2-ΔΔCt): 2.90±0.39 vs. 9.49±1.87, NLRP3 mRNA (2-ΔΔCt): 2.07±0.21 vs. 6.13±1.32, IL-1β mRNA (2-ΔΔCt): 1.43±0.24 vs. 3.95±0.51, all P < 0.05], and significantly decreased kidney tissue cell apoptosis rate [(4.36±0.92)% vs. (27.75±8.31)%, P < 0.05], and significantly increased SOD activity (kU/g: 648±34 vs. 430±47, P < 0.05).@*CONCLUSIONS@#Curcumin can alleviate kidney injury in ARDS rats, and its mechanism may be related to the increasing in SOD activity, reduction of oxidative stress, and inhibition of the activation of the NF-κB/NLRP3 inflammasome signaling pathway.

Objective: To understand the hospitalization rates and influencing factors after diagnosis among HIV infection cases, based on real-world data in Yinzhou district of Ningbo. Methods: A retrospective cohort study was conducted based on the databases of National AIDS Comprehensive Response Information Management System and Yinzhou Health Information Platform. The information about the following-up results, antiviral treatment data, electronic records of inpatient of the HIV cases reported during 2012-2020 were collected to analyze the rates, causes and influencing factors of hospitalization. Results: Among the 763 HIV infection cases reported in Yinzhou from 2012 to 2020, the hospitalization rate was 6.95% (53/763), and the number of inpatient was 2.59 per 100 person years. The hospitalization rate and the number of hospitalization per 100 person years in HIV infection cases were 3.16% (10/316) and 0.81 in those aged <30 years, 6.07% (15/247) and 1.59 in those aged >30 years, 7.86% (11/140) and 4.05 in those aged >45 years and 28.33% (17/60) and 17.40 in those aged ≥60 years respectively. Logistic multivariate regression analysis indicated that being aged ≥60 years was the influencing factor for hospitalizations in HIV infection cases (аOR=14.44, 95%CI:3.57-58.46). The hospitalization rates due to AIDS related diseases, cardiovascular diseases and metabolic diseases, and other diseases were 1.83% (14/763), 1.05% (8/763), and 3.93% (30/763), respectively. Conclusions: The hospitalization burden due to HIV infection was still mainly caused by those aged ≥60 years in Yinzhou, similar to that in general population and less proportion of hospitalizations were due to AIDS related diseases. The overall increase of hospitalizations due to AIDS was not obvious in Yinzhou.

ObjectiveTo observe the clinical effect of Jianpi Yangyin Guse decoction on patients with diabetic nephropathy (DN),and to explore its protection against podocyte injury. MethodThe enrolled 120 DN patients at stages Ⅲ and Ⅳ and diagnosed with Qi and Yin deficiency from January 2017 to January 2020 were randomly divided into observation group and control group. During the same period,20 healthy volunteers were recruited as the normal group. In addition to the basic treatment in control group,patients in the observation group were given Jianpi Yangyin Guse decoction,and the course of treatment lasted for 3 months. The traditional Chinese medicine (TCM)syndrome score,24 h urine protein (24 h UP),urine albumin-to-creatinine ratio(UACR),liver and renal functions,D-dimer, hemoglobin A1c (HbA1c), urine podocin and nephrin and α-smooth muscle actin (α-SMA) excretion of the two groups were observed before and after treatment,and the changes were statistically analyzed and compared with those in the normal group. ResultAfter treatment,the reduction of TCM syndrome score in the observation group was more significant than that in the control group(P<0.01). The 24 h UP level,UACR and renal function in the observation group in the 2nd and 3rd months after treatment were lower than the conditions before treatment(P<0.05), and those in the 3rd month after treatment were decreased compared with the conditions in the control group during the same period. The levels of podocin and nephrin in each month and the α-SMA excretion in the 3rd month after treatment in the observation group were down-regulated compared with the conditions before treatment and in the control group (P<0.05), and the observation group had reduced α-SMA excretion in the 2nd month after treatment compared with before treatment. There were no marked changes in D-dimer and liver function of the two groups before and after treatment. The level of HbA1c in the observation group was higher than that in the control group after treatment(P<0.05). ConclusionJianpi Yangyin Guse decoction has desirable clinical efficacy in DN patients,and its mechanism may be related to reducing podocin and nephrin and α-SMA excretion levels.
ABSTRACT
OBJECTIVE@#To evaluate the effectiveness of statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases by the Western guidelines in a community-based Chinese population from economically developed areas using data from the Chinese electronic health records research in Yinzhou (CHERRY) study.@*METHODS@#A Markov model was used to evaluate the effectiveness of the following statin treatment strategies, including: (1) usual care without cardiovascular risk assessment(Strategy 0); (2) using the World Health Organization (WHO) non-laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 1); (3) using the WHO laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 2); and (4) using the Prediction for Atherosclerotic cardiovascular disease Risk in China (China-PAR) model with statin treatment for high-risk group (risk ≥ 10%, Strategy 3). According to the guidelines, adults in the medium-risk group received lifestyle intervention, and adults in the high-risk group received life-style intervention and statin treatment under these strategies. The Markov model simulated different strategies for ten years (cycles) using parameters from the CHERRY study, published data, meta-analyses and systematic reviews for Chinese. The number of cardiovascular events or deaths, as well as the number need to treat (NNT) with statin per cardiovascular event or death prevented, were calculated to compare the effectiveness of different strategies. One-way sensitivity analysis on the uncertainty of incidence rate of cardiovascular diseases, and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.@*RESULTS@#Totally 225 811 Chinese adults aged 40-79 years without cardiovascular diseases at baseline were enrolled. In contrast to the usual care without risk assessment-based statin treatment strategy, Strategy 1 using the WHO non-laboratory-based risk charts could prevent 3 482 [95% uncertainty interval (UI): 2 110-4 661] cardiovascular events, Strategy 2 using the WHO laboratory-based risk charts could prevent 3 685 (95%UI: 2 255-4 912) events, and Strategy 3 using the China-PAR model could prevent 3 895 (95%UI: 2 396-5 181) events. NNTs with statin per cardiovascular event prevented were 22 (95%UI: 14-54), 21 (95%UI: 14-52), and 27 (95%UI: 17-67), respectively. Strategy 3 could prevent more cardiovascular events, while Strategies 1 and 2 required fewer numbers need to treat with statin per cardiovascular event prevented. The results were consistent in the sensitivity analyses.@*CONCLUSION@#The statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases recommended by the Western guidelines could achieve substantive health benefits in adults from developed areas of China. Using the China-PAR model for cardiovascular risk assessment could prevent more cardiovascular diseases while using the WHO risk charts seems more efficient.

OBJECTIVE@#To evaluate the effectiveness of different screening strategies for type 2 diabetes to prevent cardiovascular disease in a community-based Chinese population from economically developed areas based on the Chinese electronic health records research in Yinzhou (CHERRY) study.@*METHODS@#A Markov model was used to simulate different systematic diabetes screening strategies, including: (1) screening among Chinese adults aged 40-70 years recommended by the 2020 Chinese Guideline for the prevention and Treatment of Type 2 Diabetes (Strategy 1); (2) screening among Chinese adults aged 35 to 70 years recommended by the 2022 American Diabetes Association Standard of Medical Care in Diabetes (Strategy 2); and (3) screening among Chinese adults aged 35-70 years with overweight or obesity recommended by the 2021 United States Preventive Services Task Force Recommendation Statement on Screening for Prediabetes and Type 2 Diabetes (Strategy 3). According to the guidelines, individuals who were screened positively (fasting plasma glucose ≥ 7.0 mmol/L) would be introduced to intensive glycemic targets management (glycated hemoglobin < 7.0%).The Markov model simulated different screening scenarios for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Number of cardiovascular disease events or deaths could be prevented and number needed to screen (NNS) were calculated to compare the effectiveness of the different strategies. One-way sensitivity analysis on the sensitivity of screening methods and probabilistic sensitivity analysis on uncertainties of diabetes incidence, the sensitivity of screening methods, and intensive glycemic management effects were conducted.@*RESULTS@#Totally 289 245 Chinese adults aged 35-70 years without cardiovascular diseases or diagnosed diabetes at baseline were enrolled. In terms of the number of cardiovascular disease events could be prevented, Strategy 1 for systematic diabetes screening among the adults aged 35-70 years was 222 (95%UI: 180-264), Strategy 2 for systematic diabetes screening among the adults aged 40-70 years was 227 (95%UI: 185-271), and Strategy 3 for systematic diabetes screening among the adults aged 35-70 years with obesity or overweight (body mass index ≥ 24 kg/m2) was 131 (95%UI: 98-164), compared with opportunistic screening. NNS per cardiovascular disease event for the strategies 1, 2 and 3 were 1 184 (95%UI: 994-1 456), 1 274 (95%UI: 1 067-1 564) and 814 (95%UI: 649-1 091), respectively. Compared with Strategy 1, NNS per cardiovascular disease event for Strategy 2 increased by 90 (95%UI: -197-381) with similar effectiveness of cardiovascular prevention; however, NNS per cardiovascular disease event for Strategy 3 was reduced by 460 (95%UI: 185-724) in contrast to the Strategy 2, suggesting that the Strategy 3 was more efficient. The results were consistent in multiple sensitivity analyses.@*CONCLUSION@#Systematic screening for diabetes based on the latest guidelines in economically developed areas of China can reduce cardiovascular events and deaths. However, merely lowering the starting age of screening from 40 to 35 years seems ineffective for preventing cardiovascular disease, while screening strategy for Chinese adults aged 35-70 years with overweight or obesity is recommended to improve efficiency.

OBJECTIVE@#To describe the distribution characteristics of inflammatory bowel disease among permanent residents in Yinzhou District, Ningbo City, and to understand the disease burden and development trend of inflammatory bowel disease in this area.@*METHODS@#Using the retrospective cohort design, we collected the registration information of all permanent residents in the residents' health files of the Yinzhou Regional Health Information Platform from 2010 to 2020, and used electronic medical records to follow up their inflammatory bowel disease visits. A one-year wash-out period was set, and the patients who were diagnosed with the primary diagnosis for the first time after one year of registration were re-garded as new cases. The incidence density and 95% confidence interval (CI) of inflammatory bowel disease were estimated by Poisson distribution.@*RESULTS@#From 2011 to 2020, a total of 1 496 427 permanent residents in Yinzhou District were included, of which 729 996 were male (48.78%). The total follow-up person-years were 8 081 030.82, and the median follow-up person-years were 5.41 [interquartile range (IQR): 5.29]. During the study period, there were 1 217 new cases of inflammatory bowel disease, of which males (624 cases, 51.27%) were more than females (593 cases, 48.73%). The total incidence density was 15.06/100 000 person-years (95%CI: 14.23, 15.93). Among all new cases, there were 1 106 cases (90.88%) of ulcerative colitis, with an incidence density of 13.69 per 100 000 person-years (95%CI: 12.89, 14.52); 70 cases (5.75%) of Crohn's disease, with an incidence density of 0.87 per 100 000 person-years (95%CI: 0.68, 1.09); and 41 cases (3.37%) of indeterminate colitis, with an incidence density of 0.51 per 100 000 person-years (95%CI: 0.36, 0.69). The median age of onset of ulcerative colitis was 50.82 years old (IQR: 18.77), with the highest proportion (15.01%) in the 45-49 years group. The incidence density of ulcerative colitis gradually increased with age, reaching a relatively high level in the 45-49 years group (20.53/100 000 person-years; 95%CI: 17.63, 23.78), followed by a slight increase. And the incidence density in the 65-69 years group was the highest (25.44/100 000 person-years; 95%CI: 20.85, 30.75), with a rapid decrease in the 75-79 years group. The median age of onset of Crohn's disease was 44.34 years (IQR: 33.41), with the highest proportion (12.86%) in the 25-29 years group. Due to the small number of new cases of Crohn's disease, the age distribution fluctuated greatly, with peaks both in young and old people. From 2011 to 2020, the incidence density of inflammatory bowel disease in Yinzhou District was at a low level from 2011 to 2013, and showed a rapid upward trend from 2014 to 2016, reaching a peak of 24.62 per 100 000 person-years in 2016 (95%CI: 21.31, 28.30), and slightly decreased in 2017-2020.@*CONCLUSION@#The incidence density of inflammatory bowel disease in Yinzhou District from 2011 to 2020 was at a relatively high level, and medical institutions and health departments need to pay attention to the burden of disease caused by it.

Objective:To investigate the effect of curcumin on renal fibrosis in lipopolysaccharide (LPS) induced acute respiratory distress syndrome (ARDS) in adult SD rats.Methods:Twenty-four male SD rats were randomly (random number) divided into four groups: control group, ARDS group, low dose group, and high dose group ( n=6 per group). In the control group, the rats were given atomization intratracheal of standard saline 2 mL/kg; in the ARDS group, low-dose group, and high-dose group, the rats were given atomization intratracheal of 4 mg/kg LPS; in the low-dose group, the rats were given curcumin 100 mg/d by the oral administration, and in the high-dose group, the rats were given curcumin or 200 mg/d respectively. After seven days, the rats were sacrificed. The superoxide dismutase (SOD) activity and the content of malondialdehyde (MDA) and glutathione (GSH) in renal tissue were detected by colorimetric assay. Nuclear factor kappa-B p65 (NF-κB p65) and transforming growth factor-β1 (TGF-β1) were detected by Western blot. The expression of interleukin-6 (IL-6) mRNA, proline hydroxylase 3 (PHD3) mRNA, vascular endothelial growth factor (VEGF) mRNA and erythropoietin receptor (EPOR) mRNA were detected by quantitative real-time PCR (qRT-PCR). HE staining and Masson staining were used to assess pathological damage. One-way analysis of variance was used for comparison among multiple groups and SNK method was used for comparison between two groups. Results:Compared with the control group, the SOD activity and GSH content in the ARDS group, low-dose group, and high-dose group were significantly decreased (all P<0.05); the protein expression levels of MDA, NF-κB p65, and TGF-β1 were increased significantly, and IL-6 mRNA, PHD3 mRNA, VEGF mRNA, and EPOR mRNA were significantly upregulated (all P<0.05). HE staining showed inflammatory cell infiltration, and fibrogenesis in kidney tissue, and Masson staining showed deposition of collangen-like substance. Compared with the ARDS group, SOD activity and GSH content were increased, while the protein expression of NF-κB p65 and TGF-β1, IL-6 mRNA, PHD3 mRNA, VEGF mRNA, and EPOR mRNA were decreased significantly in the low-dose group and high-dose group (all P<0.05). Curcumin therapy reduced inflammatory cellular infiltration, and the deposition of collagen-like substance in kidney tissue. Compared with the low-dose group, SOD activity and GSH content were increased in the high-dose group (all P<0.05), and the protein expression of NF-κB p65 and TGF-β1, IL-6 mRNA, PHD3 mRNA, VEGF mRNA, and EPOR mRNA were decreased significantly in the high-dose group (all P<0.05). The high-dose group exhibited a significant reduction in edema, and a decrease of the deposition of collagen-like substance in kidney tissue. Conclusions:Curcumin can inhibit the development of renal fibrosis induced by acute respiratory distress syndrome in rats, and its mechanism may be related to inhibiting the expression of inflammatory factors and enhancing hypoxia tolerance.
ABSTRACT
Xianling Gubao is a common and effective medicine in the treatment of orthopedic diseases. In recent years, it has been reported to be associated with liver injury. However, through the analysis of the adverse drug reaction reports and key hospital cases, we found that there is considerable incomplete information in the reports of Xianling Gubao-related liver injury cases retrieved from the literature. Thus, it is difficult to accurately judge causality between the drug and liver injury. Six cases of liver injury related to Xianling Gubao were identified in key hospitals, two of which achieved the clinical diagnosis according to the assessment of the integrated evidence chain method. We further analyzed the public health data of all residents in Yinzhou. The gross incidence rate of Xianling Gubao-related liver injury was 0.034%, which corresponds to a level of rare incidence. This revealed that Xianling Gubao-related liver injury has significant divergence in individuals and an idiosyncratic nature. The gross incidence of liver injury related to Xianling Gubao was lower than that of other medicines for the treatment of orthopedic diseases. Based on the idiosyncratic drug-induced liver injury model mediated by immune stress, it was found that Epimedii Folium and Psoraleae Fructus were the major components that lead to liver injury, and the liver injury caused by a full prescription was less serious than that encountered with only Epimedii Folium and Psoraleae Fructus. This suggests that the other 4 herbs (Dipsaci Radix, Anemarrhenae Rhizoma, Rehmanniae Radix,Salviae Miltiorrhizae Radix et Rhizoma) can prevent/alleviate the liver injury. Through disassembled prescription analysis, we found that the attenuation efficacy of Salviae Miltiorrhizae Radix et Rhizoma was the most significant. In conclusion, Xianling Gubao may cause idiosyncratic liver injury in a tiny minority of susceptible individuals, but the incidence risk is lower than that of other commonly used drugs for orthopedic disease. Xianling Gubao should be discreetly applied to patients with immune stress. The major components that induced liver injury in Xianling Gubao were Epimedii Folium and Psoraleae Fructus, and Salviae Miltiorrhizae Radix et Rhizoma appears to attenuate this toxicity. This study provides a reference for the rational clinical medication with Xianling Gubao.
ABSTRACT
OBJECTIVE@#To evaluate the potential effectiveness of different screening strategies for cardiovascular diseases prevention in a community-based Chinese population from economically developed area of China.@*METHODS@#Totally 202 179 adults aged 40 to 74 years without cardiovascular diseases at baseline (January 1, 2010) were enrolled from the Chinese electronic health records research in Yinzhou (CHERRY) study. Three scenarios were considered: the screening strategy based on risk charts recommended by the 2020 Chinese guideline on the primary prevention of cardiovascular diseases in Chinese adults aged 40-74 years (Strategy 1); the screening strategy based on the prediction for atherosclerotic cardiovascular disease risk in China (China-PAR) models recommended by the 2019 Guideline on the assessment and management of cardiovascular risk in China in Chinese adults aged 40-74 years (Strategy 2); and the screening strategy based on the China-PAR models in Chinese adults aged 50-74 years (Strategy 3). According to the guidelines, individuals who were classified into medium- or high-risk groups after cardiovascular risk assessment by the corresponding strategies would be introduced to lifestyle intervention, while high-risk population would take medication in addition. Markov model was used to simulate different screening scenarios for 10 years (cycles), using parameters mainly from the CHERRY study, as well as published data, Meta-analyses and systematic reviews for Chinese populations. The life year gained, quality-adjusted life year (QALY) gained, number of cardiovascular disease events/deaths could be prevented and number needed to be screened (NNS) were calculated to compare the effectiveness between the different strategies. One-way sensitivity analysis on uncertainty of cardiovascular disease incidence rate and probabilistic sensitivity analysis on uncertainty of distributions for the hazard ratios were conducted.@*RESULTS@#Compared with non-screening strategy, QALYs gained were 1 433 [95% uncertainty interval (UI): 969-1 831], 1 401 (95%UI: 936-1 807), and 716 (95%UI: 265-1 111) for the Strategies 1, 2, and 3; and the NNS per QALY in the above strategies were 141 (95%UI: 110-209), 144 (95%UI: 112-216), and 198 (95%UI: 127-529), respectively. The Strategies 1 and 2 based on different guidelines showed similar effectiveness, while more benefits were found for screening using China-PAR models in adults aged 40-74 years than those aged 50-74 years. The results were consistent in the sensitivity analyses.@*CONCLUSION@#Screening for cardiovascular diseases in Chinese adults aged above 40 years seems effective in coastal developed areas of China, and the different screening strategies based on risk charts by the 2020 Chinese guideline on the primary prevention of cardiovascular diseases or China-PAR models by the 2019 Guideline on the assessment and management of cardiovascular risk in China may have similar effectiveness.

OBJECTIVE: To investigate the current status of pharmacists in public hospitals from Chongqing after the comprehensive reform of public hospitals, to put forward countermeasures and suggestions. METHODS: In questionnaire survey, pharmacists were selected from 33 public hospitals of secondary grade and above in Chongqing as survey objects. The current status of pharmacists in public hospitals of Chongqing from Sept. to Aug. 2018 was collected and surveyed in respects of the basic situation of pharmacists, the impact of medical reform policies, acceptance and professional development requirements of pharmacists. RESULTS: Totally 33 medical institutions included 13 third-grade hospitals and 20 secondary hospitals. A total of 838 questionnaires were distributed and 702 questionnaires were effectively recovered with effective recovery rate of 83.8%. According to the survey results, the majority of pharmacists in public hospitals of Chongqing were 25-35 years old (50.6%); 8 (1.1%) had doctor’s degree, 86 (12.3%) had master’s degree, and 25.9% had junior college and technical secondary schools. The number of master’s and doctor’s degrees in third-grade hospitals was higher than that of secondary hospitals, but there were still junior college and technical secondary school degrees in third-grade hospitals. Pharmacists were mainly referred to as middle and junior titles, 217 of which were middle-level titles (30.9%), and 434 were primary titles(61.8%); the majors were mainly pharmacy (64%), followed by traditional Chinese pharmacology (18.7%). Most of the working years were within 10 years (54.9%). There were 274 people (39.0%) with an annual income of less than 50 000 yuan, 342 people (48.7%) with an annual income of 50 000- 100 000 yuan and only 86 people (12.3%) with an annual income of more than 100 000 yuan. After the implementation of new medical reform, 430 people (61.3%) thought that the workload had increased significantly or slightly, 99 people (14.1%) thought that the scope of work was significantly expanded, and 433 people thought that the annual income after medical reform was slightly reduced or significantly reduced (61.7%); 253 people (36.0%) believed that hospital leaders did not pay attention to and did not pay much attention to pharmacists; 294 (41.9%) believed that medical staffs relatively accepted or highly accepted pharmacists. The reasons why pharmaceutical staffs thought that they were not valued mainly included five aspects, including that patients did not understand them; clinical medical staff did not agree with them; leaders did not pay attention to them; corresponding systems and regulations lacked; professional quality lacked. The main work content of pharmacists was mainly based on drug dispensing, and there were fewer people carrying out clinical pharmaceutical care, pharmacy management, pharmaceutical administration and quality control, preparation, pharmaceutical research. The jobs that they hoped to engage in were clinical pharmaceutical care, drug dispensing, pharmaceutical administration and quality monitoring, etc. Pharmacists believed that drug dispensing and delivery, reviewing medical orders, medication education guidance, consultation and medication counseling, drug management were important skills. The pharmaceutical staffs were good at skills, such as medical order review, medication education guidance, drug management. CONCLUSIONS: At present, the pharmacists in public hospitals of Chongqing have some problems, such as low education level, few clinical pharmaceutical professionals, low overall income and not recognized. It is suggested to protect the role and position of pharmacists in the medical treatment process from the perspective of introducing highly educated personnel of clinical pharmacy, improving the professional and educational structure of pharmacists, changing the pharmaceutical care mode, and improving their own ability and treatment.
ABSTRACT
Background@#The long-term predicted value of microvolt T-wave alternans (MTWA) for ventricular tachyarrhythmia in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) remains unclear. Our study explored the characteristics of MTWA and its prognostic value when combined with an electrophysiologic study (EPS) in patients with ARVC.@*Methods@#All patients underwent non-invasive MTWA examination with modified moving average (MMA) analysis and an EPS. A positive event was defined as the first occurrence of sudden cardiac death, documented sustained ventricular tachycardia (VT), ventricular fibrillation, or the administration of appropriate implantable cardioverter defibrillator therapy including shock or antitachycardia pacing.@*Results@#Thirty-five patients with ARVC (age 38.6 ± 11.0 years; 28 males) with preserved left ventricular (LV) function were recruited. The maximal TWA value (MaxValt) was 17.0 (11.0–27.0) μV. Sustained VT was induced in 22 patients by the EPS. During a median follow-up of 99.9 ± 7.7 months, 15 patients had positive clinical events. When inducible VT was combined with the MaxValt, the area under the curve improved from 0.739 to 0.797. The receiver operating characteristic curve showed that a MaxValt of 23.5 μV was the optimal cutoff value to identify positive events. The multivariate Cox regression model for survival showed that MTWA (MaxValt, hazard ratio [HR], 1.06; 95% confidence interval [CI], 1.01–1.11; P = 0.01) and inducible VT (HR, 5.98; 95% CI, 1.33–26.8; P = 0.01) independently predicted positive events in patients with ARVC.@*Conclusions@#MTWA assessment with MMA analysis complemented by an EPS might provide improved prognostic ability in patients with ARVC with preserved LV function during long-term follow-up.
