Objective: To explore whether resveratrol can reduce intestinal damage in hemorrhagic shock rats and the underlying mechanism. Methods: A total of 24 Sprague-Dawley rats of speciif c pathogen free (SPF) were randomly divided into a control group(n=8), a resveratrol group (SR group,n=8) and a vehicle group (SS group,n=8). hT e mean arterial pressure was recorded. Two hours atf er hemorrhagic shock, 15 mg/kg resveratrol or 0.3 mL equal volume of vehicle and autologous blood were given, respectively. The intestinalspecimens were collected for hematoxylin-eosin (HE) staining and calculated the pathological score. The superoxide dismutase 2 (SOD2) and cytochrome C (Cyt C) protein expression was examined by immunohistochemistry and/or Western blot. ATP level, activities of glutathione peroxidase (GXH-px), catalase (CAT) and SOD were also detected. Results: Two hours atfer autologous blood transfusion, the mean arterial pressure in the SR group was signiifcantly higher than that in the SS group (P<0.01). Compared with the SS group, the pathological injury was signiifcantly alleviated and pathological scores were dramatically reduced in the SR group (P<0.05). hTe activities of GXH-px, CAT, SOD and the ATP levels in the SR group were signiifcantly higher than those in the SS group (allP<0.01). Compared with the SS group, the SOD2 expression was significantly higher while the Cyt C expression was dramatically lower in the SR group (both P<0.01). Conclusion: Resveratrol could alleviate the intestinal injury in hemorrhagic shock rats, which might be associated with its effects on reduction of oxidative stress and protection of mitochondria.

Diabetic gastroparesis (DGP) is one of the most common complications of diabetes. Acupuncture is an ef-fective treatment for DGP in recent years. Literatures on acupuncture therapy for DGP treatment were screened for the past 10 years. Statistical analysis was made on acupoints used in the literatures in order to find the most com-monly used acupoints and combinations. This article was aimed to explore and summarize the use of the acupuncture law for the better service of clinical practice.

The influence of exercise at high temperature on adult males' routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes (PBLs) was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 180 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1 and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phlebotomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels in subgroup 1 were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na+, Cl-, Ca2+ and K+ in subgroups 1 and 2 were lower than those in control group, but CK level was higher than in control group (P<0.05). The contents of Na+ and Cl- in subgroup 1 were relatively lower than those in subgroup 2 (P<0.05). It was concluded that while receiving exercise at high temperature, adult males' HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.

Objective:To investigate the clinico-pathological characteristics and outcomes of adult patients with thin basement membrane nephropathy (TBMN).Methods:Patients with biopsy-proven TBMN in National Clinical Research Center of Kidney Diseases, Jinling Hospital during Jan 1, 2008 to Dec 31, 2017 were collected. The clinico-pathological characteristics, prognosis, the influencing factors of proteinuria and renal chronic lesions were retrospectively analyzed.Results:Among 135 adult patients included, 116 cases (85.9%) were female, and 19 cases were males. The age was (40.56±10.30) years old. There were 30 cases (22.2%) with hypertension and 32 cases (23.7%) with overweight or obesity. Proteinuria was found in 41 patients (30.4%) with (0.65±0.19) g/24 h of urine protein, and microscopic hematuria was found in all 135 patients. Serum creatinine was normal in all patients. Glomerulosclerosis was observed in 102 cases (75.6%), in which 51 cases (37.8%) had glomerulosclerosis>10%. There were 79 cases (58.5%) with mild chronic tubulointerstitial lesions, and 53 patients (39.3%) with vascular hyalinosis. The proportions of proteinuria, chronic tubular interstitial lesion and renal vascular lesion in patients with overweight/obesity and/or hypertension were higher than those without complications (all P<0.05). Multivariate logistic regression results showed that overweight/obesity ( OR=7.550, 95% CI 2.091-27.257, P=0.002) and hypertension ( OR=4.424, 95% CI 1.091-17.935, P=0.037) were independent influencing factors for proteinuria, while proteinuria was the independent influencing factor for chronic tubular interstitial lesion ( OR=3.151, 95% CI 1.046-9.491, P=0.041). Four patients were lost to follow-up, and the median follow-up time of the remaining patients was 64.0(24.0, 96.5) months. At the end of the follow-up, urine protein increased in 10 patients (7.4%) and estimated glomerular filtration rate decreased in 3 patients (2.2%). The above 13 cases were all complicated with overweight/obesity and 4 cases with hypertension. The urine test and renal function in the remaining 118 patients didn't change significantly from baseline. Conclusions:The incidences of proteinuria and renal chronic lesion are high in adult TBMN patients. Overweight/obesity and hypertension may cause a poor prognosis, and TBMN patients without metabolic abnormalities probably have good prognosis, but need long-term follow-up.

Methods: The number,content and pageview of the information about COVID-19 on WeChat official accounts of one provincial and eleven municipal CDCs from January 20 to February 5 were collected and analyzed. The number of new followers and WeChat communication power index (WCI) were employed to evaluate the communication effect. Results: By February 5,those WeChat public official accounts pushed 629 pieces of information about COVID-19. The pageviews were 3 713 428 in total and 5 903.70 on average. There were totally 633 008 followers,including 110 341 new followers which contributed to a growth rate of 21.11%. The average WCI was 677.81. The WCIs of eight official accounts were higher than 500,with “Zhejiang Health Education” the highest (1 021.95). The daily pageviews peaked on January 20,21,25 and 31. Among the top 15 pieces of information in pageviews,there were 7 pieces for epidemic announcements,3 pieces for popular science and 5 pieces for behavioral intervention. Conclusions The WeChat official accounts of CDCs in Zhejiang Province pushed the information about COVID-19 in line with the progress of the epidemic and the demand of the public,leading to a higher attention and better communication effect.

{L-End}Objective To understand the prevalence of work-related musculoskeletal disorders (WMSDs) and sickness absence due to WMSDs among key industry workers in Shenzhen City. {L-End}Methods A total of 14 949 workers exposed to dust, noise, chemical and radiation (hereinafter referred to as "traditional occupational groups") in some key industries in Shenzhen City, as well as bus drivers, teachers, medical staff, policemen, courier, sanitation workers and video operators were selected as the research subjects using stratified cluster sampling. The Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of WMSDs and sickness absence due to WMSDs in the past year. {L-End}Results The overall prevalence of WMSDs among the study subjects was 56.3% (8 423/14 949). The prevalence of WMSDs in different body parts from high to low was neck, waist, shoulder, back, knee, wrist, ankle, hip, and elbow, which was 37.6%, 35.7%, 31.7%, 25.2%, 18.3%, 15.4%, 14.9%, 12.4%, and 11.6%, respectively (P<0.01). The overall prevalence of WMSDs among different occupational groups from high to low was teachers, video operators, bus drivers, couriers, medical staff, policemen, traditional occupational groups, and sanitation workers, which was 82.2%, 75.7%, 74.9%, 73.9%, 67.9%, 64.3%, 43.3%, and 31.9%, respectively (P<0.01). The overall rate of sickness absence due to WMSDs was 18.3% (2 736/14 949). The overall rate of sickness absence among different occupational groups from high to low was bus drivers, couriers, teachers, traditional occupational groups, policemen, video operators, medical staff, and sanitation workers, which was 31.6%, 24.5%, 20.9%, 20.2%, 15.2%, 12.4%, 9.3%, and 6.7%, respectively (P<0.01). Among different parts of the body, the highest correlation coefficient of WMSDs was found between neck and shoulder ［correlatioon cofficient (r)=0.648, P<0.01］, while the lowest was between neck and ankle (r=0.303, P<0.01). {L-End}Conclusion The prevalence of WMSDs and sickness absence due to WMSDs among key industry workers in Shenzhen City is relatively high. Comprehensive prevention and control measures should be taken according to the characteristics of occupational population to reduce the impact of WMSDs on the health of occupational population.

{L-End}Objective To investigate the prevalence of neck and waist work-related musculoskeletal disorders (WMSDs) and its relationship with occupational stress among express delivery workers. {L-End}Methods A total of 437 express delivery workers in Shenzhen City were selected as the research subjects using convenient sampling method. The prevalence of neck and waist WMSDs and the level of occupational stress were investigated by the Musculoskeletal Disorder Questionnaire and Work Content Questionnaire. {L-End}Results The prevalences of neck and waist WMSDs among the workers in the past year were 47.6% (208/437) and 60.2% (263/437), respectively. The detection rate of occupatioonal stress was 51.5%(225/437). The prevalences of neck and waist WMSDs among the workers of the occupational stress group were higher than that in the non-occupational stress group (51.9% vs 42.6%, 66.4% vs 53.0%, both P<0.01). The results of multivariate logistic regression analysis showed that the risk of neck WMSDs was higher in workers with weekly working hours >40 hours, workers with poor working posture, and workers with occupational stress compared with workers with weekly working hours ≤40 hours, workers without poor working posture, and workers without occupational stress, respectively (all P<0.05). The risk of waist WMSDs was higher in workers without weekly exercise, workers with poor working posture, and workers with occupational stress compared with workers with weekly exercise, workers without poor working posture, and workers without occupational stress, respectively (all P<0.05). {L-End}Conclusion The prevalence of neck and waist WMSDs, which may be influenced by occupational stress and poor working postures, is relatively high among express delivery workers.

Objective: To understand the current situation and associated factors of cellphone usage and addiction among Chinese children and adolescents, to provide reference for effective prevention and intervention of cellphone addiction. Methods: Using a stratified random sampling approach, 11 213 children and adolescents and their parents from 31 provinces, municipalities and autonomous regions in China were recruited and surveyed. Results: The median of daily mobile phone use time among Chinese children and adolescents were 120.00 minutes, as reported by either children or parents. Child s age( β =0.12), hedonic( β =0.11) and social( β =0.09) cellphone use motivations positively related to time spent on cellphone( P <0.01). Cellphone related parental communication( β =-0.06) and knowledge( β =-0.03), as well as cellphone usage on instrumental( β =-0.04) or self representation( β =-0.16) motivation negatively related to time spent on cellphone( P <0.05). Child s age( β =-0.04), cellphone related parental communication( β =-0.09) and awareness( β =-0.14), cellphone use on instrumental motivation( β =-0.22) were negatively associated with cellphone addiction among children and adolescents( P <0.05). Cellphone related parental monitoring( β =0.07), as well as cellphone usage on self representation motivation( β =0.03) or hedonic motivation( β =0.29) positively related to cellphone addiction in children and adolescents( P <0.05). Conclusion Time spent on mobile phone and mobile phone addiction of Chinese children and adolescents are influenced by various internal and external factors, such as the mobile phone use motivation and parenting style.Future school education should help children develop scientific motivation for mobile phone use. Family education should help parents develop positive parenting behaviors such as communication and awareness, so as to reduce the possibility of improper mobile phone use.
