Global Burden of Cardiovascular Disease Attributable to High Temperature in 204 Countries and Territories from 1990 to 2019 / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease (CVD) burden from 1990 to 2019.@*METHODS@#Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019. Deaths and disability-adjusted life years (DALYs) were used to quantify heat-induced CVD burden. We calculated the age-standardized mortality rate (ASMR) and DALY rate (ASDR) per 100,000 population to compare this burden across regions. Generalized linear models were applied to evaluate estimated annual percentage changes (EAPC) for temporal trends from 1990 to 2019. The correlation between the socio-demographic index (SDI) and age-standardized rate was measured using the Spearman rank test.@*RESULTS@#Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019. Global ASMR and ASDR of heat-related CVD in 2019 were 1.17 [95% confidence interval ( CI): 0.13-1.98] and 25.59 (95% CI: 2.07-44.17) per 100,000 population, respectively. The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019. ASMR showed an upward trend, with the most considerable increase in low-latitude countries. We observed a negative correlation between SDI and EAPC in ASMR ( r s = -0.57, P < 0.01) and ASDR ( r s = -0.59, P < 0.01) among 204 countries.@*CONCLUSION@#Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.

Related factors of viral nucleic acid change in critically ill patients with SARS-CoV-2 infection after treatment with Nirmatrelvir/Ritonavir: a single center retrospective cohort study / 中华危重病急救医学

OBJECTIVE@#To describe negative conversion and rebound of patients with severe and critical acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection after treatment with Nirmatrelvir/Ritonavir, and to analyze related factors associating with failure of SARS-CoV-2 negative conversion and relapse and prognosis.@*METHODS@#A single center retrospective cohort study was conducted. Patients aged ≥ 16 years old who were diagnosed with severe or critical SARS-CoV-2 infection and took Nirmatrelvir/Ritonavir for 5 days in Peking University First Hospital from December 7, 2022 to January 27, 2023, were included. General characteristics and clinical data were collected from electronic medical record system. The Kaplan-Meier curve of SARS-CoV-2 negative conversion was drawn. Factors with P < 0.10 were incorporated into multivariate Logistic regression model to analyze the relationship between the factors and persistent nucleic acid positive and rebound.@*RESULTS@#A total of 31 severe and 37 critical SARS-CoV-2 infection patients were included. The median duration from initiation of Nirmatrelvir/Ritonavir to negative conversion of SARS-CoV-2 for both was 6.0 days, and the negative conversion rate on day 15 was 93.5% and 86.5%, respectively. SARS-CoV-2 rebound was observed in 7 patients (11.3%), among whom were 1 severe patient and 6 critical patients. The above 7 patients with SARS-CoV-2 rebound and 6 patients with failure of SARS-CoV-2 negative conversion were compared with 55 patients with persistent negative conversion. Factors with P < 0.10, including the lowest lymphocyte count (LYM), the highest D-dimer, the highest procalcitonin (PCT), the lowest Ct value, cardiovascular diseases other than hypertension and coronary heart disease, were incorporated into multivariate Logistic regression analysis. The decreased LYM [odds ratio (OR) = 0.146, 95% confidence interval (95%CI) was 0.031-0.689, P = 0.015] and the increased PCT (OR = 2.008, 95%CI was 1.042-3.868, P = 0.037) were revealed to be independent risk factors of the failure of SARS-CoV-2 negative conversion or rebound. The proportion of mechanical ventilation and invasive ventilation were significantly higher in patients with persistent SARS-CoV-2 infection or rebound than those in patients with SARS-CoV-2 negative conversion (84.6% vs. 38.2%, 69.2% vs. 25.5%, both P < 0.01), but no significant difference in mechanical ventilation and invasive ventilation duration was observed. Compared with the patients with SARS-CoV-2 negative conversion, more patients with persistent SARS-CoV-2 infection or rebound were admitted to intensive care unit (ICU, 76.9% vs. 50.9%), and length of ICU stay in patients with persistent SARS-CoV-2 infection or rebound tended to be longer [days: 13.0 (10.3, 24.3) vs. 11.0 (5.3, 23.0), P > 0.05].@*CONCLUSIONS@#The decreased LYM and increased PCT are independent risk factors for the failure of SARS-CoV-2 negative conversion or rebound in patients with severe and critical SARS-CoV-2 infection. Attention should be paid to these patients for their poor prognosis.

Early therapeutic interventions of traditional Chinese medicine in COVID-19 patients: A retrospective cohort study / 中西医结合学报

OBJECTIVE@#To observe the early interventions of traditional Chinese Medicine (TCM) on the conversion time of nucleic acid in patients with coronavirus disease 2019 (COVID-19), and find possible underlying mechanisms of action.@*METHODS@#A retrospective cohort study was conducted on 300 confirmed COVID-19 patients who were treated with TCM, at a designated hospital in China. The patients were categorized into three groups: TCM1, TCM2 and TCM3, who respectively received TCM interventions within 7, 8-14, and greater than 15 days of hospitalization. Different indicators such as the conversion time of pharyngeal swab nucleic acid, the conversion time of fecal nucleic acid, length of hospital stay, and inflammatory markers (leukocyte count, and lymphocyte count and percentage) were analyzed to observe the impact of early TCM interventions on these groups.@*RESULTS@#The median conversion times of pharyngeal swab nucleic acid in the three groups were 5.5, 7 and 16 d (P < 0.001), with TCM1 and TCM2 being statistically different from TCM3 (P < 0.01). TCM1 (P < 0.05) and TCM3 (P < 0.01) were statistically different from TCM2. The median conversion times of fecal nucleic acid in the three groups were 7, 9 and 17 d (P < 0.001). Conversion times of fecal nucleic acid in TCM1 were statistically different from TCM3 and TCM2 (P < 0.01). The median lengths of hospital stay in the three groups were 13, 16 and 21 d (P < 0.001). TCM1 and TCM2 were statistically different from TCM3 (P < 0.01); TCM1 and TCM3 were statistically different from TCM2 (P < 0.01). Both leucocyte and lymphocyte counts increased gradually with an increase in the length of hospital stay in TCM1 group patients, with a statistically significant difference observed at each time point in the group (P < 0.001). Statistically significant differences in lymphocyte count and percentage in TCM2 (P < 0.001), and in leucocyte count (P = 0.043) and lymphocyte count (P = 0.038) in TCM3 were observed. The comparison among the three groups showed a statistically significant difference in lymphocyte percentage on the third day of admission (P = 0.044).@*CONCLUSION@#In this study, it was observed that in COVID-19 patients treated with a combination of Chinese and Western medicines, TCM intervention earlier in the hospital stay correlated with faster conversion time of pharyngeal swab and fecal nucleic acid, as well as shorter length of hospital stay, thus helping promote faster recovery of the patient. The underlying mechanism of action may be related to improving inflammation in patients with COVID-19.

OBJECTIVE@#Traditional Chinese medicine plays a significant role in the treatment of the pandemic of coronavirus disease 2019 (COVID-19). Tanreqing Capsule (TRQC) was used in the treatment of COVID-19 patients in the Shanghai Public Health Clinical Center. This study aimed to investigate the clinical efficacy of TRQC in the treatment of COVID-19.@*METHODS@#A retrospective cohort study was conducted on 82 patients who had laboratory-confirmed mild and moderate COVID-19; patients were treated with TRQC in one designated hospital. The treatment and control groups consisted of 25 and 57 cases, respectively. The treatment group was given TRQC orally three times a day, three pills each time, in addition to conventional Western medicine treatments which were also administered to the control group. The clinical efficacy indicators, such as the negative conversion time of pharyngeal swab nucleic acid, the negative conversion time of fecal nucleic acid, the duration of negative conversion of pharyngeal-fecal nucleic acid, and the improvement in the level of immune indicators such as T-cell subsets (CD3, CD4 and CD45) were monitored.@*RESULTS@#COVID-19 patients in the treatment group, compared to the control group, had a shorter negative conversion time of fecal nucleic acid (4 vs. 9 days, P = 0.047) and a shorter interval of negative conversion of pharyngeal-fecal nucleic acid (0 vs. 2 days, P = 0.042). The level of CD3@*CONCLUSION@#Significant reductions in the negative conversion time of fecal nucleic acid and the duration of negative conversion of pharyngeal-fecal nucleic acid were identified in the treatment group as compared to the control group, illustrating the potential therapeutic benefits of using TRQC as a complement to conventional medicine in patients with mild and moderate COVID-19. The underlying mechanism may be related to the improved levels of the immune indicator CD3

Comparative study of prognostic nutritional index and patient-generated subjective global assessment in perioperative nutritional prediction in patients with esophageal cancer / 中国胸心血管外科临床杂志

@#Objective    To investigate the prognostic value and consistency of prognostic nutritional index (PNI) and patient-generated subjective global assessment (PG-SGA) in perioperative nutritional status of patients with esophageal cancer. Methods    Clinical data of 224 patients, including 186 males and 38 females with an average age of 63.08±8.42 years, who underwent esophageal cancer surgery in our hospital from November 2017 to August 2018 were retrospectively reviewed. The PNI was calculated according to the results of the first time blood and biochemical tests, and the PG-SGA assessment was also performed. According to the PNI value, the patients were divided into a good nutrition group (PNI≥45, 60 patients) and a malnutrition group (PNI<45, 164 patients). According to the PG-SGA score, the patients were divided into a good nutrition group (PG-SGA<4, 75 patients) and a malnutrition group (PG-SGA≥4, 149 patients). Nutrition-related haematological indexes and body mass index (BMI) were compared between the two groups, and the consistency of PNI and PG-SGA for nutritional assessment was analyzed. Results    The nutrition-related haematological indexes in different PNI groups were statistically different in the perioperative period (P<0.01). The longitudinal changes of prealbumin in patients of different PG-SGA groups were statistically different (P<0.05); the BMI of patients in different PG-SGA groups was statistically different in the perioperative period (P<0.01). The Kappa coefficient of the two indicators was 0.589 (P<0.001). Conclusion    Both PNI and PG-SGA can predict the nutritional risk of patients with esophageal cancer to some extent. PNI is an objective monitoring indicator, and PG-SGA is a subjective evaluation indicator, the combined use of which can more comprehensively reflect and predict the nutritional status of patients, and provide an important reference to the development of individualized nutrition support programs.

Fatty acid quantification method by isobutyl esterification and GC-FID/MS / 上海交通大学学报（医学版）

Objective:To establish a quantification method for understanding the varieties and concentrational changes of fatty acids under physiological and pathophysiological conditions. Methods:Based on isobutyl esterification using (-)-menthyl chloroformate and isobutanol, 27 typical fatty acids were qualitatively and quantitatively analyzed by gas chromatography-flame ionization detector/mass spectrometry (GC-FID/MS). The sensitivity and stability of the method were detected by limit of detection (LOD), limit of quantification (LOQ), and intra-day and inter-day relative standard deviation (RSD). The method was applied to four typical biological samples (human serum, urine, feces and rat liver) to verify the universality in different substrates. Results:Isobutyl esters of 27 fatty acids were effectively separated with an HP-5MS column. The results showed nice linearity within 2-3 orders of magnitude in terms of concentration with R2>0.99 for all 27 tested fatty acids. The LODs of the method were between 0.03 and 2.96 pmol on column whereas the LOQs were between 0.09 and 9.86 pmol. The results of method validation showed that the intra-day and inter-day RSDs were all under 10% in the range of high, medium and low concentrations. With this method, moreover, 10, 7, 14 and 9 fatty acids were detected in human serum, urine, feces and rat liver, respectively. Conclusion:A quantitative analytical method for fatty acids with short, media and long chains (C1-C24) is established based on isobutyl estrification in aqueous media. This method has the advantages of mild condition, high sensitivity, good stability, and simple and quick operation, and can be directly used in the detection of serum, urine, feces, liver and other biological samples, which may provide a new idea for high-throughput metabolome analysis.

Diagnostic Utility of Interferon-Gamma Release Assay in Tuberculous Lymphadenitis / 中国医学科学杂志(英文版)

Objective The aim of this study was to evaluate the diagnostic performance of T-SPOT.TB for tuberculous lymphadenitis. Methods Suspected tuberculous lymphadenitis patients between September 2010 and September 2018 who had both peripheral blood T-SPOT.TB test and lymph node biopsy were retrospectively enrolled in this study. The cutoff value of T-SPOT.TB test for peripheral blood was set as 24 spot forming cell (SFC)/10 6 periphreral blood monocyte cell (PBMC) according to the instruction of testing kits. The gold standard for diagnosis of TBL was the combination of microbiology results, histopathology results and patient's response to anti-TB treatment. Diagnostic efficacy of T-SPOT.TB was evaluated, including sensitivity, specificity, accuracy, predictive values, and likelihood ratio. Results Among 91 patients who met the inclusion criteria, we excluded 8 cases with incomplete clinical information and 6 cases who lost to follow-up. According to the gold standard, there were 37 cases of true TBL (9 confirmed TBL and 28 probable TBL), 30 cases of non-TBL, and 10 cases of clinically indeterminate diagnosis who were excluded from the final analyses. The T-SPOT.TB tests yielded 43 cases of positive response and 24 cases of negative response. The sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR) and negative likelihood ratio (NLR) of peripheral blood T-SPOT.TB for diagnosing TBL were 89.2%, 66.7%, 79.1%, 76.7%, 83.3%, 2.68 and 0.16, respectively. The number of SFCs of T-SPOT.TB in TBL patients [432(134-1264)/10 6 PBMCs] was higher than that in non-TBL patients [0 (0-30) /10 6PBMCs] with a significant difference (Z=-5.306, P <0.001). Conclusion T-SPOT.TB is a rapid and simple diagnostic test for TBL with a high sensitivity and negative predictive value.

Characteristics and Impact Factors of Renal Threshold for Glucose Excretion in Patients with Type 2 Diabetes Mellitus

Sodium glucose co-transporter 2 (SGLT-2) inhibitors are newly developed but promising medicine for type 2 diabetes. However, patients with a different renal threshold for glucose excretion (RT(G)) may have a different reaction to this medicine. Therefore, the objective of this study was to investigate the characteristics of RT(G) and its impact factors in patients with type 2 diabetes mellitus (T2DM). The clinical and laboratory data of 36 healthy individuals and 168 in-hospital patients with T2DM were collected and analyzed, RTG was calculated using blood glucose (BG) measured by dynamic BG monitoring, urinary glucose excretion (UGE) and estimated glomerular filtration rate (eGFR). The characteristics of RT(G) were investigated. The risk factors for high RT(G) were analyzed using non-conditional logistic regression analysis. Our results found that RT(G) of the T2DM group was higher than that of the healthy individuals (P < 0.05); and 22.22% from the healthy individuals group but 58.33% from the T2DM group had high RT(G). Age, duration of diabetes, body mass index (BMI), and homeostasis model assessment insulin resistance index (HOMA-IR) were independently associated with high RT(G) (P < 0.05). Further stratified analysis revealed that RT(G) in T2DM patients increased with age, duration of diabetes, and BMI. In conclusion, RT(G) is increased in patients with T2DM, especially in those with longer diabetic duration, higher BMI, and those who are older. Therefore, these patients may be more sensitive to SGLT-2 inhibitors.

Changes of choroidal thickness and hemodynamic parameters and their influencing factors in patients with diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

?AIM: To study the changes of choroidal thickness and hemodynamic parameters in patients with diabetic retinopathy and their influencing factors.?METHODS: From January 2013 to January 2015, 100 patients (100 eyes) with type 2 diabetes were divided into 3 groups:34 patients without diabetic retinopathy ( NDR) , 36 patients with non proliferative diabetic retinopathy ( NPDR) group, and 30 patients with proliferative diabetic retinopathy (PDR). According to the results of OCT, the patients with diabetic retinopathy were divided into 2 groups: diabetic macular edema ( DME ) group ( 28 cases) , and 38 cases without diabetic macular edema. During the same period in our hospital 35 subjects for physical examination were selected as the control group. The hemodynamic parameters of the posterior ciliary artery in different groups of patients at different distance from the center of the macular were compared, analyzing influencing factors.?RESULTS:With the aggravation of diabetic retinopathy, the choroidal thickness in different distance from the center of the macular decreased. The choroidal thickness of NPDR and PDR group were thinner than that of the control group (P0. 05). There was no significant difference in the choroidal thickness between the DME patients and non DME patients (P>0. 05). Pearson correlation analysis showed that there was no significant correlation between choroidal thickness of patients with diabetic retinopathy and diabetic duration, fasting blood glucose, HbA1c, eye axis length, systolic blood pressure and diastolic blood pressure (P>0. 05), but there was a correlation with BCVA (logMAR) (P<0. 01). EDV and PSV in NDR group and NPDR group were significantly lower than those in control group, RI was higher than that in control group. PSV and EDV in PDR group were significantly lower than those in other three groups, RI was higher than the other three groups, and the difference was statistically significant ( P<0. 05).?CONCLUSION:With the severity of retinopathy in type 2 diabetic patients, the choroidal thickness decreased, and the thickness of the choroid is beneficial in the comprehensive analysis of 2 diabetic retinopathy.

Research progress on Nrf2-ARE signaling pathway involved in liver disease pathological mechanism / 中国药理学通报

Nuclear factor erythroid-2 related factor 2 ( Nrf2 ) is an important nuclear transcription factor which protects cells a-gainst oxidative stress injury. Upon exposure to reactive oxygen species ( ROS) or electrophilic stress, Nrf2 can translocate into the nucleus, and then bind to the antioxidant response element ( ARE) , regulating the expression of several antioxidant enzymes and phase Ⅱ detoxifying enzymes which aimed at the detoxifica-tion and elimination of harmful exogenous chemicals, resulting in the facilitation of hepatoprotection. Oxidative stress is the com-mon pathogenesis of many liver diseases, while the Nrf2-ARE signaling pathway is extremely important in the prevention and progression of many liver diseases. Nrf2 has more recently been implicated as a new therapeutic target in treating liver diseases. Here, we focus on the most common liver diseases and the devel-opment of these conditions where activation of Nrf2 may alleviate disease progression, so as to provide reference for related re-search in the future.

Progress on mechanism of Tripterygium wilfordii-induced liver injury and detoxification mechanism of licorice / 中国中药杂志

Tripterygium wilfordii has exihibited multiple pharmacological activities, such as anti-inflammatory, immune modulation, anti-tumor and anti-fertility. T. wilfordii have been used for the therapy of inflammation and autoimmune diseases including rheumatoid arthritis, immune complex nephritis and systemic lupus erythematosus clinically. However, it is well known that T. wilfordii has small margin between the therapeutic and toxic doses and could cause serious injury on digestive, reproductive and urogenital systems. Among all the organs, liver is one of the most remarkable targets of T. wilfordii-induced toxicities, and the damage is more serious than others. It is generally accepted that T. wilfordii-induced liver injury is a result of the combined effects of toxic elements of T. wilfordii. It is reported in several studies that the mechanism of T. wilfordii-induced liver injury may be related to lipid peroxidation, cell apoptosis and immune damage, and so on. Licorice is one of the most commonly used Chinese herbal medicine, with effects of heat- clearing and detoxicating, anti-inflammatory and hepatoprotective, reconciling various drugs, and so on. Licorice often accompany T. wilfordii in clinical application which can significantly reduce the liver injury induced by T. wilfordii. The attenuated effect is exact, but the mechanism is still a lack of in-depth study. This paper reviews the studies on T. wilfordii-induced liver injury and the related mechanism as well as licorice and other traditional Chinese medicine accompany T. wilfordii to reduce the injury in recent years, so as to provide reference for related research in the future.

Nursing intervention and evaluation of postoperative pain in preschool children with cleft lip and palate / 华西口腔医学杂志

<p><b>OBJECTIVE</b>This study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief.</p><p><b>METHODS</b>A total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared.</p><p><b>RESULTS</b>The postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001).</p><p><b>CONCLUSION</b>Postoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.</p>
