ABSTRACT

Objective To evaluate the effectiveness of a whole-process health education model among inpatients with ascites type of advanced schistosomiasis. Methods A “admission-hospitalization-discharge” whole-process health education model was created, 101 inpatients with ascites type of advanced schistosomiasis were given the whole-process health education. The scores of schistosomiasis control knowledge, attitudes towards schistosomiasis control and healthy behaviors, and awareness of schistosomiasis control knowledge, correct rate of attitudes towards schistosomiasis control and correct rate of healthy behaviors were compared among inpatients with ascites type of advanced schistosomiasis before and after implementation of the whole-process health education. Results The scores of schistosomiasis control knowledge, schistosomiasis control attitudes and healthy behaviors were all significantly higher among inpatients with ascites type of advanced schistosomiasis after implementation of the whole-process health education than before implementation (Z = −7.688, −3.576 and −4.328, all P values < 0.01). In addition, the awareness of schistosomiasis control knowledge increased from 54.3% to 82.7% (χ2 = 188.886, P < 0.01), and the correct rate of attitudes towards schistosomiasis control increased from 88.4% to 98.0% (χ2 = 22.001, P < 0.01), while the correct rate of healthy behaviors increased from 48.2% to 59.7% (χ2 = 11.767, P < 0.01). Conclusions The whole-process health education model may remarkably improve the awareness of schistosomiasis control knowledge and promote the formation of positive attitudes towards schistosomiasis control and correct behaviors among inpatients with ascites type of advanced schistosomiasis, which is of great significance to facilitate patients’ cure.

ABSTRACT

Objective@#To explore the effectiveness of spinal guidance exercise on adolescents of mild idiopathic scoliosis, so as to provide an experimental reference and method for promoting adolescents spinal health.@*Methods@#From the scoliosis screening, 96 children who met the diagnostic criteria were selected in June 2021, and were divided into the experimental group and the control group, with 48 cases in each group. The experimental group received a 12 week Longji Daoyin exercise training, and the control group received health education, observation and monitoring. Before and after the experiment, the axial trunk rotation (ATR) and scoliosis Cobb angle of the two groups were tested respectively, and the subjective sensation of the patients was measured by Scoliosis Research Society-22(SRS-22) questionnaire.@*Results@#After 12 weeks, the ATR and Cobb angles of the experimental group decreased [( 5.02± 2.85,7.59±3.94)°],compared to (7.08±2.84)° and (15.84±2.00)° before intervention( t =14.02, 17.09, P < 0.01 ). Scores of functional activity, self image and mental health in the SRS-22 score increased from (4.65±0.14)(3.49±0.21) and (3.99±0.17) to(4.77±0.14)(4.62±0.13)(4.42±0.13)( t =-4.86,-39.12,-13.92, P <0.01 ). The ATR and Cobb angles of the control group increased from (6.94±2.15)° and (15.82±1.76)° to (8.25±2.49)° and (18.63±3.12)°( t =7.44,8.99, P <0.01), and the scores of self image and mental health in the SRS-22 score decreased from (3.49±0.19) and (4.00±0.15) to (3.44±0.18) and (3.94±0.14)( t =-3.74,-4.39, P <0.05).@*Conclusion@#Early adolescent idiopathic scoliosis is easy to aggravate during the observation period. Longji Daoyin exercise is of preventive and therapeutic significance.

ABSTRACT

OBJECTIVES@#The use of anticholinergic drugs in the elderly may lead to negative events such as falls, delirium, urinary retention and cognitive decline, and the higher the number of anticholinergic drugs use, the more such negative events occur. This study aims to analyze the risk factors associated with the prescription of total anticholinergic drugs in elderly outpatients and evaluate the rationality of anticholinergic drugs, and to provide a reference for reducing the adverse effects of anticholinergic drugs.@*METHODS@#A list of drugs with anticholinergic activity based on the Beers criteria was established. The basic information (such as age and gender), clinical diagnosis, and medications of elderly outpatient were extracted from hospital electronic medical records, and the Anticholinergic Cognitive Burden (ACB) Scale was used to calculate the anticholinergic burden for each patient. Logistic regression analysis was used to identify the potential risk factors for the occurrence of problems such as multiple medication and insomnia.@*RESULTS@#A total of 1 840 prescriptions for elderly patients were reviewed. Of these patients, ACB score was more than or equal to 1 in 648 (35.22%) patients. Number of prescription medication (95% CI: 1.221 to 1.336) and insomnia (95% CI: 3.538 to 6.089) were independent factors affecting ACB scores (both P<0.01). Medications for patients of ACB scores were most commonly treated with the central nervous system drugs (such as alprazolam and eszopiclone) and for the cardiovascular system drugs (such as metoprolol and nifedipine).@*CONCLUSIONS@#There is a high rate of ACB drugs use in geriatric patients, and the clinical focus should be on multiple medication prescriptions, especially on the central nervous system drugs (such as alprazolam and eszopiclone) and cardiovascular system drugs (such as metoprolol and nifedipine). The prescription review should be emphasized to reduce adverse reactions to anticholinergic drugs in elderly patients.

ABSTRACT

Tripterygium glycosides liposome(TPGL) were prepared by thin film-dispersion method, which were optimized accor-ding to their morphological structures, average particle size and encapsulation rate. The measured particle size was(137.39±2.28) nm, and the encapsulation rate was 88.33%±1.82%. The mouse model of central nervous system inflammation was established by stereotaxic injection of lipopolysaccharide(LPS). TPGL and tripterygium glycosides(TPG) were administered intranasally for 21 days. The effects of intranasal administration of TPG and TPGL on behavioral cognitive impairment of mice due to LPS-induced central ner-vous system inflammation were estimated by animal behavioral tests, hematoxylin-eosin(HE) staining of hippocampus, real-time quantitative polymerase chain reaction(RT-qPCR) and immunofluorescence. Compared with TPG, TPGL caused less damage to the nasal mucosa, olfactory bulb, liver and kidney of mice administered intranasally. The behavioral performance of treated mice was significantly improved in water maze, Y maze and nesting experiment. Neuronal cell damage was reduced, and the expression levels of inflammation and apoptosis related genes [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), BCL2-associated X(Bax), etc.] and glial activation markers [ionized calcium binding adaptor molecule 1(IBA1) and glial fibrillary acidic protein(GFAP)] were decreased. These results indicated that liposome technique combined with nasal delivery alleviated the toxic side effects of TPG, and also significantly ameliorated the cognitive impairment of mice induced by central nervous system inflammation.

ABSTRACT

Objective:To investigate the role of protein phosphatase 4 catalytic subunit (PP4C) in regulating hepatitis B virus X protein (HBx) levels and its effects on the biological functions of HBx, thus to provide a potential therapeutic targets for hepatitis B virus (HBV)-related hepatocellular carcinoma.Methods:In vivo and in vitro interactions between HBx and PP4C were analyzed by co-immunoprecipitation (Co-IP) and GST pull-down assay. Recombinant plasmids of PP4C and HBx were co-transfected with Lipofectamine 3000 reagents into hepatoma cells to detect the protein levels of HBx by Western blot. The half-life of HBx in the transfected cells treated with cycloheximide (CHX) were detected. The phosphorylation assay was used to evaluate the effects of PP4C on HBx phosphorylation. CCK8 assay, wound healing assay and Matrigel invasion chamber assay were used to analyze the effects of PP4C on the biological functions of HBx. Results:PP4C interacted with HBx in vivo and in vitro. PP4C overexpression significantly increased the protein level and stability of HBx and the phosphorylation assay confirmed that PP4C overexpression decreased the serine phosphorylation of HBx in hepatoma cells. PP4C overexpression enhanced the migration and invasion of hepatoma cells, but had no significant effects on the proliferation. Conclusions:The interactions between HBx and PP4C promoted the stability of HBx and ultimately enhanced the migration and invasion of hepatoma cells, and the mechanisms might be related to the decrease of HBx serine phosphorylation by PP4C. This study provided a theoretical basis for further investigation of the pathogenic mechanisms of HBx, and targeting PP4C and HBx interaction might provide insights for developing novel treatment for HBV-related hepatocellular carcinoma.

ABSTRACT

Aerobic glycolysis is a metabolic process in which cellular energy production favors the low-efficiency energy-producing glycolytic pathway in the presence of sufficient oxygen, reducing dependence on aerobic respiration, while producing energy rapidly and providing advantages for cell survival and proliferation. In recent years, several studies have shown that aerobic glycolysis is involved in the development of renal interstitial fibrosis (RIF) and involves various cell types such as fibroblasts, endothelial cells, renal tubular epithelial cells, pericytes, and inflammatory cells. Drugs targeting glycolysis may provide new ideas for the prevention and treatment of RIF. This article reviews the research progress of abnormal aerobic glycolysis in different cells and glycolytic intervention drugs in RIF.

ABSTRACT

Myeloid sarcoma (MS) is a tumor mass formed by the proliferation of one or more myeloid primitive cells outside the marrow, which is mostly related to acute myeloid leukemia (AML). It is reported that 2.5% to 9.1% of AML patients have MS, and AML with spinal canal MS is very rare. Spinal canal MS often has an acute onset and is difficult to diagnose. It is easy to cause missed diagnosis and misdiagnosis, which will lead to a delay in accurate diagnosis seriously affecting the treatment and quality of life among these patients. The clinical data, diagnosis and treatment process of a case of MS with multiple space occupying lesions in the spinal canal diagnosed and treated by the Department of Hematology of Peking Union Medical College Hospital are reported, in order to provide reference for clinical workers.

ABSTRACT

As early as the 20 th century, it has been observed that radiotherapy (RT), as a local therapy, can activate the adaptive immune system, resulting in spontaneous regression of tumors out of the radiation field, which is known as "abscopal effect". Although the occurrence of abscopal effect is still rare, with the gradual increase in the application of immunotherapy, more and more clinical cases of abscopal effect have been reported. Increasing attention has been paid to the therapeutic potential of RT in inducing systemic anti-tumor response. Especially, the combination of RT and immunotherapy enhances the research value of abscopal effect. However, its mechanism has not been fully elucidated, and the optimal timing, dose and fractionation of RT are also under study. How to classify the beneficiary groups is also a key issue. In this article, the history of abscopal effect, and the role of RT and immunotherapy in this phenomenon were briefly introduced, and the existing controversies in clinical application were illustrated, aiming to clarify the direction of current research and development and open a new chapter for tumor treatment in a short period of time.

ABSTRACT

Objective:To explore the detection rate, clinical characteristics of vulvar squamous intraepithelial lesion (SIL).Methods:Women diagnosed with vulvar high-grade squamous intraepithelial lesions (HSIL) through colposcopy-guided biopsy from January 1, 2018 to August 31, 2022 in Obstetrics and Gynecology Hospital of Fudan University were included in a 1∶1 ratio with patients diagnosed with vulvar low-grade squamous intraepithelial lesions (LSIL) during the same period. Clinical characteristics including human papillomavirus (HPV) infection rate, genotype, cytology result, colposcopy impression, and lesion location were retrospectively analyzed.Results:(1) The proportion of vulvar SIL detected by colposcopy-guided biopsy increased annually from 2018 to 2022, with rates of 1.64% (740/45 057), 2.34% (1 110/47 402), 2.68% (1 108/41 335), 3.26% (1 536/47 078), 3.31% (667/20 155), with an average rate of 2.57% (5 161/201 027). (2) A total of 1 096 cases of vulvar HSIL and 1 096 cases of vulvar LSIL were included. The overall infection rate of HPV was 92.7% (1 993/2 150), with higher infection rate in vulvar HSIL patients than that in vulvar LSIL patients [96.0% (1 012/1 054) vs 89.5% (981/1 096); χ2=33.62, P<0.001]. Among vulvar HSIL patients, the common HPV genotype from high to low were HPV 16 (66.7%), HPV 52 (14.3%), and HPV 58 (10.0%). For vulvar LSIL patients, the most common HPV genotype were respectively HPV 16 (24.9%), HPV 6 (20.1%) and HPV 52 (17.1%). The overall sensitivity rate of cytology was 53.6%, with no significance difference between vulvar LSIL and HSIL groups (54.3% vs 52.9%; χ2=0.40, P=0.526). The accuracy of colposcopy impression for vulvar HSIL was lower than that for vulvar LSIL [40.2% (163/405) vs 81.7% (380/465); χ2=158.72, P<0.001]. About 57.3% (1 257/2 192) of the patients had concomitant cervical and vaginal lesions, with a higher rate in vulvar HSIL group than that in vulvar LSIL group [62.6% (686/1 096) vs 52.1% (571/1 096); χ2=24.67, P<0.001]. Unifocal lesion was the main type, with no significance difference between vulvar LSIL and HSIL groups [81.4% (381/468) vs 82.5% (386/468); χ2=0.18, P=0.671]. The most common lesion locations were the posterior commissure, followed by labia minora, vaginal vestibule, labia majora, perianal and clitoris. Conclusions:The detection rate of vulvar SIL under colposcopy is about 3%, and the infection rate of HPV is 92.7%. Vulvar SIL, especially vulvar HSIL, is likely to cause concomitant cervical and vaginal lesions. The accuracy of colposcopy in diagnosing vulvar HSIL is low. Therefore a comprehensive and careful examination of the vulva is necessary and suspicious vulvar lesions should be undergone colposcopy-guided biopsy for diagnosis.

ABSTRACT

Objective:To explore the effect and mechanism of diosmetin (Dio) on neuronal ferroptosis in rats with bacterial meningitis (BM).Methods:Male SD rats aged 6-7 weeks of SPF grade were selected for the experiment. The BM model was established by injecting group B hemolytic streptococcus into the cisterna magna of cerebellum. Sixty BM model rats were successfully modeled and divided into model group, low-dose Dio group, medium-dose Dio group, high-dose Dio group and inhibitor group according to the random number table method, with 12 rats in each group. Another 12 weight-matched rats were taken as the control group.The rats in the low-dose Dio group, medium-dose Dio group, high-dose Dio group and the inhibitor group were intragastrically administered with Dio at 50 mg/kg, 100 mg/kg, 200 mg/kg and 200 mg/kg, respectively. The rats in the control group were intragastrically administered with an equal volume of 0.9 % sodium chloride solution. On the day of intragastric administration, the rats in the inhibitor group were intraperitoneally injected with SIRT1 pathway inhibitor EX527 (10 mg/kg), and the rats in the other groups were injected with an equal volume of 0.9% sodium chloride solution. The above interventions were performed once a day for 28 consecutive days. Loeffler neurological score was used to evaluate the neurological impairment in rats. Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in cerebrospinal fluid of rats were detected by ELISA. The number of white blood cells in cerebrospinal fluid was detected by a blood cell analyzer. Glutathione (GSH) was detected by micro-enzyme labeling method, malondialdehyde (MDA) was detected by thiobarbituric acid colorimetric method, reactive oxygen species(ROS) was detected by colorimetry, and Fe 2+ level was detected by ferrozine method. Hematoxylin-eosin staining, Prussian blue staining and TUNEL staining were used to observe the pathological damage, iron accumulation and apoptosis in the hippocampus, respectively.Western blot was applied to measure the expression of transferrin (Tf), proliferating cell nuclear antigen (PCNA), Bcl-2-associated X protein (Bax), caspase-3 and SIRT1/Nrf2/HO-1/Gpx4 signaling pathway proteins. Graphpad Prism 9.0 was used for data analysis. One-way ANOVA was used for statistical analysis, and SNK- q test was used for further pairwise comparisons. Results:(1) There was a statistically significant difference in neurological function scores among the 6 groups of rats ( F=125.451, P<0.001). The neurological function score of the model group was lower than that of control group, while the neurological function scores of the low-dose Dio group, medium-dose Dio group, and high-dose Dio group were higher than those of the model group (all P<0.05). The neurological function score of the inhibitor group ((2.57±0.26)) was lower than that of high-dose Dio group ((4.34±0.48)) ( P<0.05). (2) There were statistically significant differences in the levels of IL-6, TNF-α and the number of white blood cells in the cerebrospinal fluid of rats among the 6 groups ( F=127.817, 102.413, 180.967, all P<0.001). The levels of IL-6, TNF-α and the number of white blood cells in model group were higher than those of control group(all P<0.05). The levels of IL-6, TNF-α and the number of white blood cells in low-dose Dio group, medium-dose Dio group and high-dose Dio group were lower than those of model group (all P<0.001), and those in inhibitor group were all higher than those in high-dose Dio group(all P<0.001). (3) There were statistically significant differences in iron deposition rate and neuronal apoptosis rate among the 6 groups of rats ( F=90.857, 88.835, both P<0.001). The iron deposition rate ((18.37±3.14)%) and neuronal apoptosis rate ((27.58±2.63)%) in the inhibitor group were higher than those in the high-dose Dio group ((6.35±1.08)%, (14.02±1.87)%) (both P<0.05). (4) The levels of GSH, ROS, MDA, and Fe 2+ in the hippocampus of the 6 groups of rats showed statistically significant differences ( F=54.465, 106.453, 55.969, 105.457, all P<0.001). The GSH content in the inhibitor group ((103.48±8.76) mmol/g) was lower than that in the high-dose Dio group ((133.97±10.54) mmol/g), while the contents of ROS, MDA, Fe 2+ ((225.17±16.32) μmol/mg, (10.73±1.58) μmol/mg, (62.71±5.43) μg/g) were higher than those of the high-dose Dio group ((131.87±11.67) μmol/mg, (4.35±0.87) μmol/mg, (34.86±2.95) μg/g) (all P<0.05). (5)There were statistically significant differences in the protein levels of Tf, PCNA, Bax, caspase-3, SIRT1, Nrf2, HO-1 and Gpx4 in the hippocampus of the 6 groups of rats ( F=120.179, 107.568, 157.265, 98.031, 90.932, 52.283, 59.424, 114.539, all P<0.001). The protein levels of Tf, Bax and caspase-3 in the hippocampus of inhibitor group were higher than those of the high-dose Dio group, while the protein levels of PCNA, SIRT1, Nrf2, HO-1, Gpx4 were lower than those of the high-dose Dio group (all P<0.05). Conclusion:Diosmetin can activate SIRT1/Nrf2/HO-1/Gpx4 signaling pathway, thereby inhibiting neuronal ferroptosis in BM rats.

ABSTRACT

Objective:To investigate the effects of fluoride exposure on autophagy and the expression levels of adenosine monophosphate activated protein kinase (AMPK), mammalian target of rapamycin (mTOR) and Unc-51-like kinase 1 (ULK1) in mouse neuroblastoma and rat glioma fusion cells (NG108-15 cells).Methods:NG108-15 cells were cultured in vitro and divided into control group (0 mg/L), low fluoride group (20 mg/L), medium fluoride group (40 mg/L) and high fluoride group (80 mg/L) according to the final concentration of sodium fluoride, and the cells were collected after 24 h of treatment for standby. NG108-15 cells autophagy was detected by immunofluorescence/immunocytochemistry (IF/ICC method, the autophagy positive control group was treated with chloroquine phosphate); the mRNA expression levels of AMPK, mTOR and ULK1 in each group were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR); the protein expression levels of autophagy related protein microtubule-associated protein 1 light chain 3B (LC3B), AMPK, mTOR, ULK1, phosphorylation (p)-AMPK, p-mTOR, p-ULK1 in each group were detected by Western blotting. Results:No autophagosome was detected in the control group, and autophagosomes were detected in all the fluoride groups. The protein expression level of LC3B in the low, medium and high fluoride groups (1.80 ± 0.59, 2.16 ± 0.60, 2.30 ± 0.57) was significantly higher than that in the control group (1.00 ± 0.29, P < 0.05). The results of qRT-PCR showed that compared with the control group, the mRNA expression levels of AMPK in medium and high fluoride groups were higher (2.30 ± 0.57, 4.41 ± 1.05 vs 1.00 ± 0.01, P < 0.05); the mRNA expression levels of mTOR in the low, medium and high fluoride groups were lower (0.79 ± 0.04, 0.76 ± 0.09, 0.64 ± 0.10 vs 1.00 ± 0.01, P < 0.05), and the mRNA expression levels of ULK1 were higher (1.81 ± 0.39, 1.96 ± 0.35, 4.22 ± 1.03 vs 1.00 ± 0.01, P < 0.05). The results of Western blotting showed that compared with the control group, the protein expression levels of AMPK (1.21 ± 0.05, 1.20 ± 0.04, 1.30 ± 0.07 vs 1.00 ± 0.03), p-AMPK (1.12 ± 0.05, 1.20 ± 0.06, 1.49 ± 0.07 vs 1.00 ± 0.02), ULK1 (1.16 ± 0.05, 1.26 ± 0.05, 1.15 ± 0.05 vs 1.00 ± 0.04) and p-ULK1 (1.19 ± 0.04, 1.17 ± 0.02, 1.24 ± 0.05 vs 1.00 ± 0.05) in the low, medium and high fluoride groups were higher ( P < 0.05), and the protein expression levels of mTOR were lower (0.77 ± 0.03, 0.60 ± 0.03, 0.55 ± 0.04 vs 1.00 ± 0.04, P < 0.05); the protein expression levels of p-mTOR in the medium and high fluoride groups were lower (0.93 ± 0.05, 0.48 ± 0.02 vs 1.00 ± 0.02, P < 0.05). Conclusion:Fluoride exposure can induce autophagy in NG108-15 cells, and the expression of AMPK and ULK1 are up-regulated, while the expression of mTOR is down-regulated.

ABSTRACT

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

ABSTRACT

Objective:To study the practical efficacy of the clinical decision support system for diagnosis and treatment of thyroid cancer (CDSS-TC) in assisting doctors to complete several diagnosis and treatment tasks, and to make a preliminary evaluation of its clinical practicability according to the test results.Methods:From Jan. 2022 to Mar. 2022, 90 patients with thyroid cancer who were admitted to the Head and Neck Surgery Department of Shaw Hospital affiliated to Zhejiang University were prospectively analyzed, and the average time spent in reading the pre-operative B-ultrasound report, as well as the individual fitness of the dose adjustment of eugenol in 70 patients with thyroid cancer after surgery. A retrospective analysis was made of the compliance of the basis of the "recommended scheme" and the deviation of the basis of the doctor’s "final scheme" for the preoperative surgery of 120 patients with thyroid cancer who were treated for the first time in the head and neck surgery of Shaw Hospital affiliated to Zhejiang University from Mar. 2021 to May. 2021. All cases were treated by pure artificial (group A) and CDSS-TC assisted (group B) , and the differences in organization were compared.Results:The average time for disposal of a single B-ultrasound report in Group B was much shorter than that in Group A ( P=5.600E-04) ; The number of patients with excellent grade and the total number of patients with excellent grade and qualified grade recommended by the doctor in group B were significantly higher than those in group A ( P=7.819E-20 and P=1.335E-18) ; The conformity rate of the basis of CDSS-TC "Recommended Scheme" ≥ 98%; The deviation rate of the basis for "final protocol" of doctors in group B was lower than that in group A ( P=0.059 for total resection or not, P=0.075 for lateral neck dissection or not) . Conclusions:CDSS-TC can accurately extract the disease-related source information in all the original examination/laboratory reports, and provide accurate decision-making suggestions through efficient correlation analysis. In view of the accurate and objective conclusions of its analysis, it can provide high-quality and all-link decision support for doctors’ clinical diagnosis and treatment, and is an ideal information work platform.

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.

ABSTRACT

Objective To investigate the effects of Akkermansia muciniphila (AKK) on azomethane-oxide (AOM)/glucan sodium sulfate (DSS)-induced inflammatory colorectal cancer mouse model and intestinal stem cells. Methods AOM/DSS-induced mouse models of inflammatory-associated colorectal cancer were randomly divided into three groups, namely, model, AKK and aspirin groups, based on different administration of drugs by gavage. The tumor number, size, distribution, and burden were observed 10 weeks after intervention. Immunohistochemical method was used to analyze the expressions of Ki67 and Lgr5 proteins, which are utilized to characterize tumor malignancy and stem cells. The mRNA expressions of Lgr5, CD133, Nanog, and ALDH1 were detected by qRT-PCR. Results Compared with those of the model group, the tumor number, size, and burden of the AKK group were significantly reduced (P < 0.01). The expressions of Ki67 and Lgr5 in the AKK group of tumor tissues were significantly decreased (P < 0.05), and the mRNA expressions of CD133, Nanog and ALDH1 were significantly down-regulated. Conclusion AKK is effective against AOM/DSS-induced colitis-associated colorectal cancer in mice, and its mechanism of action may be closely related to colorectal stem cell activity.

ABSTRACT

Shanghai municipal administration of market supervision focuses on "the people's city built by the people, and the people's city for the people". Through the regular "you order, I inspect" activities on food safety the administration has established an important window for disseminating market regulation information, showcasing the image of market regulation, and telling the story of market regulation. Over the past three years, by combining the needs of the citizens in Shanghai and the routine food safety spot-checking plan through the food safety “you order,I inspect” activities, the administration has enabled the public to perceive and evaluate the quality of the inspection services, and has actively built a food safety social co-governance service brand. While ensuring that people can eat at ease and buy at will, we will also boost consumer confidence and promote high-quality development of food safety, so as to create a vivid picture of people participating in and benefiting from food safety governance.

ABSTRACT

@#Objective    To explore the relationship between myocardial viability in patients with coronary artery disease who underwent elective coronary artery bypass grafting (CABG) and early application of intra-aortic balloon pump (IABP) after coronary revascularization, and to provide relevant clinical reference for the pre-implantation of 16G single-lumen catheter in the femoral artery of high-risk patients to facilitate the addition of IABP after operation. Methods    This retrospective study included 521 patients (414 males and 107 females, aged 62.50±8.82 years) who underwent positron emission tomography (PET)-computed tomography (CT) perfusion-metabolism imaging prior to CABG surgery in our institution from December 2015 to August 2020. The myocardial viability information and left ventricular functional parameters were measured, including the proportion of non-viable myocardium (perfusion-metabolic imaging match), hibernating myocardium (perfusion-metabolic imaging mismatch) and dysfunctional myocardium (non-viable+viable myocardium), left ventricular ejection fraction, left ventricular end-diastolic volume and left ventricular end-systolic volume (LVESV). The patients were divided into an IABP group and a non-IABP group  according to whether they received IABP treatment after revascularization. The clinical data were reviewed and compared to explore significant impact factors between the two groups. And the multivariate logistic regression analysis was performed to investigate the correlation between preoperative myocardial viability and early use of IABP after CABG. Results    In multivariate logistic regression analysis, the amount of non-viable, dysfunctional myocardium and LVESV value were identified as the independent predictors for the probability of IABP use in the initial postoperative period. Receiver operating characteristic analysis showed that 9.5% non-viable myocardium, 19.5% dysfunctional myocardium, and LVESV of 114.5 mL were the optimal cutoff for predicting early IABP implantation during CABG. Conclusion    The myocardial survival status displayed by preoperative PET-CT myocardial perfusion-metabolism imaging can predict the possibility of applying IABP in CABG perioperative period. In addition to routine pre-anesthesia assessment, anesthesiologists can conduct risk stratification assessment for patients with CABG according to the results of preoperative myocardial viability imaging, which is of great significance to ensure the perioperative safety of high-risk patients with CABG.

ABSTRACT

Cannabinoid receptors are one of the most expressed G protein-coupled receptors in the central nervous system, which are potential drug targets for inflammation, pain and drug abuse. Cannabinoid receptors are composed of type 1 receptor (CB1R), type 2 receptor (CB2R) and other receptors, of which CB1R plays a vital role in regulating central memory, cognition, and motor function. Therefore, screening CB1R agonists has potential value in treating nervous system diseases. In this study, the intracellular loop 3 (ICL3) domain of CB1R was replaced with a circular-permutated enhanced green fluorescent protein (cpEGFP). After infecting HEK 293T cells with lentivirus particles, we obtained a stable cell line that was overexpressed human CB1R-cpEGFP after puromycin selection. The interaction between receptor agonists and CB1R led to the change of receptor conformation, resulting in de-protonation of the EGFP, and enhancing the fluorescence intensity. Therefore, active CB1R compounds could be verified by measuring the fluorescence intensity. Using CB1R agonist arachidonyl-2′-chloroethylamide (ACEA) as a positive control to evaluate the reliability of this model, studies have shown that ACEA could induce receptor activation and increase fluorescence intensity, while antagonist rimonabant inhibited receptor activation with unchanged fluorescence intensity. In conclusion, this study successfully constructed a fluorescent probe screening model for CB1R agonists.

ABSTRACT

AIM: To analyze the clinical characteristics and treatment of patients with acute acquired concomitant esotropia(AACE)in different refractive status.METHODS: A retrospective analysis was conducted on 110 patients with non-type I AACE treated from January 2020 to January 2022. The non-myopic group(30 cases, spherical equivalent&#x003E;-0.5D)and the myopic group(80 cases, spherical equivalent≤-0.5D)were divided according to the refractive status. The degree of deviation, accommodative convergence and accommodation ratio(AC/A), visual function, and surgical methods were observed. RESULTS: The non-myopic group had no difference in the degree of near deviation [(47.13±23.54)△] and the degree of distant deviation [(48.90±22.59)△](P&#x003E;0.05); near deviation [(40.49±26.09)△] of myopic group was less than distant deviation [(50.09±25.41)△](P&#x003C;0.001); and there was no difference in the same distance between the two groups(P&#x003E;0.05). AC/A in the non-myopic group(5.40±2.23)was higher than that in the myopic group(3.14±3.10; P&#x003C;0.05). Patients in the myopic group had better near stereopsis than the non-myopic group(P&#x003C;0.05). The non-myopic group had a variety of surgical methods, while the myopic group mostly used lateral rectus resection or/and medial rectus recession.CONCLUSION: AACE can occur in different refractive status. Non-myopic patients have the same degree of distant and near strabismus, high AC/A, and varied surgical methods. However, myopic patients have less degree of near deviation than distant deviation and have normal AC/A and better near stereopsis, and lateral rectus resection or/and medial rectus recession are commonly used.

ABSTRACT

In order to standardize the quality control of traditional Chinese medicine(TCM) dispensing granules, the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules, but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022, 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules, involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards, this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example, and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials, contents of index components and their transfer rates, specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed, in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.
