Objective To study the distribution characteristics of TCM constitutions in the middle-aged and elderly Mongolian population undergoing physical examinations in Inner Mongolia;To analyze the correlation with related risk factors.Methods Health information and related risk factors(including BMI index,lifestyle habits,dietary habits and exercise status)of middle-aged and elderly Mongolian people who visited the physical examination departments of Inner Mongolia Autonomous Region Traditional Chinese Medicine Hospital and Tongliao City Traditional Chinese Medicine Hospital from March 2024 to April 2024 were collected.A total of 213 Mongolian people were surveyed,including 65 people who have lived in Hohhot for more than 2 years and 148 people who have lived in Tongliao for more than 2 years.Through investigation,research and analysis,the distribution characteristics of TCM constitutions in the population and its correlation with related risk factors were observed.Results Constitution distribution:101 people(47.41%)had a moderate constitution.Among the biased constitutions,the phlegm dampness constitution had the highest number of people(64 people,30.05%),with the blood deficiency constitution having the lowest number of people(2 people,0.94%).In the investigation of related risk factors,there was a significant correlation(P<0.01)between phlegm dampness and dietary habits and reduced exercise volume.Moreover,individuals with this constitution tend to have good sleep,reduced physical activity,faster eating and a diet primarily consisting of high-calorie foods(P<0.05).Conclusion The TCM constitution of the Mongolian population in Inner Mongolia is mostly composed of moderate constitution,while the biased constitution is mostly composed of phlegm dampness constitution,which is mainly related to dietary habits and reduced exercise volume.

Background Under the background of global warming, research on association between ambient temperature and risk of injury is needed. Objective To examine the effect of temperature on injury in Bao'an district, Shenzhen and identify the sensitive population, thereby providing a scientific basis for formulating prevention and control strategies and measures of injury. Methods The injury reports from the Injury Surveillance System and the meteorological data of Bao'an District between 2018 to 2022 were collected. The meteorological data were sourced from the fifth generation of the European Centre for Medium-Range Weather Forecasts (ECMWF) land reanalysis data. Based on time-stratified case-crossover design, conditional logistic regression combined with distributed lag nonlinear model was used to evaluate the exposure-response association between ambient temperature and injury. The stratified analyses were further conducted by gender, age, and causes of injury. Results A total of 156205 injury cases were collected from the injury surveillance sentinel hospitals in Bao'an District of Shenzhen from 2018 to 2022, and the median of daily average temperature during the same period was 20.0 ℃. The exposure-response curve showed that the risk of injury was positively correlated with temperature. The linearized analysis revealed that each 1°C increase in temperature was associated with a 1.05% (95%CI: 0.68%, 1.42%) rise in injury risk (ER). Notably, the effect was greater in females (ER=1.31%, 95%CI: 0.67%, 1.94%) than males (ER=0.92%, 95%CI: 0.47%, 1.37%). Among age groups, adults ＞60 years faced the highest risk (ER=1.91%, 95%CI: −0.36%, 4.24%). The top three temperature-associated injury risks were sharp instrument injuries (ER=2.19%, 95%CI: 1.16%, 3.22%), animal injuries (ER=1.71%, 95%CI: 0.86%, 2.56%), and blunt injuries (ER=071%, 95%CI: −0.08%, 1.51%). The impact of temperature on unintentional injuries (ER=1.11%, 95%CI: 0.72%, 1.49%) was higher than that on intentional injuries (ER=0.43%, 95%CI: −0.85%, 1.72%). Severe injuries (ER=2.20%, 95%CI: −3.09%, 7.77%) were more affected by temperature than mild injuries (ER=1.00%, 95%CI: 0.58%, 1.43%) and moderate injuries (ER=1.15%, 95%CI: 0.42%, 1.89%). Conclusion The increase in ambient temperature associates with injury occurrence, and the impact of temperature exhibits obvious heterogeneity among different populations, indicating that targeted intervention measures should be taken for different populations and types of injuries.

BACKGROUND:Currently,numerous observational studies have frequently associated dietary antioxidant intake and circulating antioxidant levels with osteoarthritis.Nevertheless,the underlying causal mechanisms remain unclear.Therefore,this study employs publicly available genome-wide association data to investigate the causal associations between antioxidant intake,circulating levels,and osteoarthritis,offering evidence for the prevention and treatment of osteoarthritis.OBJECTIVE:To assess the potential causal associations between dietary antioxidants(including vitamins A,C,E,and carotenoids)and circulating antioxidants(such as Glutathione S-transferase,glutathione peroxidase,catalase,superoxide dismutase,ascorbic acid,α-tocopherol,γ-tocopherol,albumin,uric acid,bilirubin,zinc,and selenium)with osteoarthritis through Mendelian randomization.METHODS:Data from genome-wide association studies on four dietary antioxidants and twelve circulating antioxidants were employed as exposure variables.The outcome variable was the osteoarthritis consortium dataset,which comprised 77 052 osteoarthritis cases and 378 169 healthy controls.Causal effects were evaluated using the inverse variance-weighted method,MR-Egger regression,and the weighted median approach.Stability and reliability of the findings were assessed through horizontal pleiotropy tests and sensitivity analyses.RESULTS AND CONCLUSION:(1)These results demonstrated that dietary vitamin C intake was inversely associated with knee osteoarthritis risk(OR=0.83,95%CI:0.71-0.96,P=0.015).Conversely,vitamin E intake was positively associated with knee osteoarthritis(OR=1.20,95%CI:1.05-1.34,P=0.004)and both knee and hip osteoarthritis(OR=1.15,95%CI:1.03-1.27,P=0.008).(2)Circulating antioxidant albumin levels were negatively associated with knee(OR=0.94,95%CI:0.91-0.97,P=0.001),hip(OR=0.95,95%CI:0.91-0.99,P=0.03),and knee or hip osteoarthritis(OR=0.95,95%CI:0.92-0.98,P=0.01).Uric acid levels were positively associated with knee osteoarthritis(OR=1.10,95%CI:1.03-1.17,P=0.003).(3)Sensitivity analyses yielded consistent results without evidence of horizontal pleiotropy.(4)European genome-wide data indicated that vitamin C intake was associated with a decreased risk of knee osteoarthritis,and lower serum albumin levels were associated with reduced risks of knee and hip osteoarthritis.In contrast,vitamin E intake and higher serum uric acid were associated with an increased risk of knee osteoarthritis.These findings support public health education and osteoarthritis interventions,indicating that serum albumin could be a potential biomarker for risk assessment.(5)The study underscores the role of certain antioxidants in osteoarthritis prevention and provides evidence to inform nutritional guidelines and public health strategies for the Chinese population.Furthermore,it contributes to biomarker research in arthritis,facilitating the development of early diagnostic tools and risk assessment strategies for the Chinese population.

Objective To analyze the epidemiological characteristics of population-based cohort of patients with the comorbidity of cardiovascular and cerebrovascular diseases and type 2 diabetes in Lingnan area,and to study the related influencing factors in the onset and progression of the disease. Methods A retrospective cohort study was used to collect data from people who underwent physical examination in the Eleventh People's Hospital of Guangzhou from May 2022 to December 2023. Data mainly included questionnaire surveys,physical examinations,and laboratory testing indicators. The 2022 was defined as the baseline to statistically analyze the occurrence and development of the comorbidity of cardiovascular and cerebrovascular diseases and type 2 diabetes in this population,and to analyze the related influencing factors of comorbidity and distribution of traditional Chinese medicine constitution in comorbidity population. Results Finally,a total of 26498 subjects were included,from which there were 359 patients with the comorbidity of cardiovascular and cerebrovascular diseases and type 2 diabetes (comorbidity group),accounting for 1.4％ of the total. Among them,290 were male,accounting for 80.8％,which is much higher than female. The mean age was(61.6±9.5)years old,which was significantly higher than that of the non-comorbidity group. The cases of comorbidity group were mainly concentrated in the age group of 45-75 years old,and no cases were found in people under 35 years old. There were 293 patients with the comorbidity of ischemic cardiovascular disease and type 2 diabetes,whose proportion (81.6％) is much higher than that of other types. Significant differences between comorbidity group and non-comorbidity group were found in terms of gender,age,age distribution,height,body mass,body mass index (BMI),smoking,alcohol consumption,marital status,exercise,and dampness syndrome (P<0.05). About 1.0％ of population at the baselined converted from non-comorbidities or single disease to comorbidities. The proportion of newly diagnosed patients with the comorbidity of ischemic cardiovascular disease and type 2 diabetes is the highest,up to 68.9％. BMI overweight or obesity,large waist circumference,smoking,dampness syndrome and exercise were the risk factors affecting the comorbidity of cardiovascular and cerebrovascular diseases and type 2 diabetes. A total of 264 cases of comorbidity group had finished evaluation of traditional Chinese medicine body constitutions. The proportion of balanced constitution was the highest (31.1％),followed by dampness-heat constitution (18.2％),yang-deficiency constitution (13.3％) and phlegm-dampness constitution (11.7％). Conclusion The incidence of the comorbidity of cardiovascular and cerebrovascular diseases and type 2 diabetes is high in Lingnan area,which may be related to dampness constitution,BMI overweight or obesity,large waist circumference,smoking,dampness syndrome and lack of exercise.

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Objective:To investigate the long-term clinical value of composite biomaterial mesh in inguinal hernia repair.Methods:The prospective randomized controlled non-inferiority study was conducted. The clinical data of 172 adult patients with inguinal hernia who were admitted to 3 medical centers, including Huadong Hospital Affiliated to Fudan University et al, from July 2014 to February 2015 were selected. Based on random number table, patients were divided into two groups. Patients underwent technique of abdominal wall reinforcement with biological mesh. Patients using the electrospun composite biomaterial mesh were allocated into experimental group, and patients using the small intestinal submucosa mesh were allocated into control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) endpoint of the study. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Taking the recurrence rate of hernia at 6 years after surgery as the basis of efficacy evaluation, the Cochran-Mantel-Haenszel test was used for comparison between groups. The confidence interval method was used to conduct non-inferiority statistical analysis. If the lower limit of 95% confidence interval of the difference of recurrence rate of hernia between the experiment group and the control group was more than -10%, the experiment group was considered to be non-inferior to the control group. If the lower limit of 95% confidence interval is more than 0, the experiment group was considered to be superior to the control group. Results:(1) Grouping situations of the enrolled patients. A total of 172 adult patients with inguinal hernia were selected for eligibility. They were males, aged (61±2)years. All 172 patients were randomly divided into to the experimental group and the control group with 86 cases in each group. At 6 years after surgery, 20 patients in the experi-mental group and 19 patients in the control group was lost to follow-up. (2) Endpoint of the study. ① The primary endpoint of study. At 6 years after surgery, no patient had recurrence in the 66 patients of experimental group and 4 patients had recurrence in the 67 patients of control group. Results of non-inferiority statistical analysis showed that the 95% confidence interval of the difference of recurrence rate of hernia between the two groups was 0.27% to 14.41%, with the lower limit as 0.27%, which was more than -10% and simultaneously more than 0. ② The secondary endpoint of study. There was no significant difference in the simple verbal scale between the two groups after 6 months and 6 years at rest or cough status ( P>0.05). At a follow-up of 6 months after surgery, 2 cases of the experimental group and 5 patients of the control group had complications, showing no significant difference between the two groups( χ2=1.38, P>0.05). At a follow-up of 6 years after surgery, no complication occurred in either group. Conclusion:Composite biological mesh in inguinal repair is safe and feasible, which can have low long-term recurrence and achieve good long-term efficacy.

Objective:To explore the role of internal stenting for preventing biliary anastomotic complications during complex duct-to-duct biliary reconstruction of orthotopic liver transplantation.Methods:From December 1, 2018 to April 30, 2020, intraductal stent was placed in 6 cases of complex biliary tract reconstruction during liver transplantation. Postoperative prognosis, recovery of bilirubin and biliary enzymes, management of intraductal stent and occurrence of postoperative biliary complications were observed.Results:All of them recovered and were discharged smoothly and bilirubin and biliary enzymes normalized before discharge. The average peak values of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase were 83.8±56.4 μmol/L, 151.5±76.3 U/L, 301.7±177.0 U/L and 98.4±80.9 μmol/L and the average turning points of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 2.3±1.0, 3.0±1.1, 3.8±1.2 and 1.8±0.8 days; average time of complete recovery of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 7.7±5.1, 5.0±4.9, 23.5±7.6 and 3.8±2.4 days respectively. Intraductal stent was removed by gastroduodenoscopy ( n=3) and slipped off ( n=3). Except for one case of asymptomatic anastomotic stricture at 1 year post-operation, no biliary complications occurred during follow-ups. Conclusions:The placement of intraductal stent during complex biliary reconstruction of liver transplantation can effectively promote the recovery of postoperative liver function, enhance the quality-of-life of patients, effectively avoid the occurrence of biliary anastomotic complications and ensure the safety of patients.

Objective:To compare the application value of different polypropylene mesh in inguinal hernia repair of adults.Methods:The prospective cohort study was conducted. The clinical data of 120 adult patients with inguinal hernia who were admitted to two medical centers (60 in Huadong Hospital affiliated to Fudan University and 60 in Shanghai Ninth People′s Hospital affiliated to Shanghai Jiaotong University from March 2012 to Match 2014 were collected. Patients were randomly divided into study group and control group using the random number table. Patients in the study group underwent repair of inguinal hernia using the SMP95958X mesh, and patients in the control group underwent repair of inguinal hernia using the modified Kugel mesh. All patients underwent preperitoneal repair by senior hernia surgery specialists. Observation indicators: (1) postoperative pain; (2) complications and follow-up. Patients were followed up at postoperative 3 months and 6 months using outpatient examination to detect the short-term complications by physical or color doppler ultrasonography examination, and at postoperative 5 years using telephone interview or outpatient examination to detect long-term complications including infection, foreign body sensation and recurrence of hernia. The follow-up was up to March 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), comparison between groups was analyzed using the nonparametric rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square, continuous correction chi-square test or Fisher exact probability. Comparison of ranked data were analyzed using the nonparametric rank sum test. Results:A total of 118 patients with inguinal hernia were selected for eligibility, including 116 males and 2 females, aged (64±12)years, with a range from 29 to 84 years. Of the 118 patients, 59 were in the study group and 59 were in the control group, respectively. (1) Postoperative pain: of the 59 patients in the control group, 34 took painkiller and 1 case lost the data of taking painkiller at postoperative 2 days. Of the 59 patients in the study group, 29 cases took painkiller. There was no significant difference in taking painkiller between the two groups ( χ2=1.055, P>0.05).
