Objective: To explore the effect of aerobic plus resistance training on the intervention of adolescents with moderate mental retardation and to provide reference for healthy development among specific need population. Methods: Totally 29 adolescents with moderate mental retardation, aged 12-17 years from one middle school in Shunde district of Foshan, were divided into intervention group and control group (16/13) with random number table. The intervention group was subjected to aerobic combined resistance exercise for 11 weeks. The control group maintained the original activities. The changes in body composition, muscle strength, cardiorespiratory endurance and balance ability of the two groups of subjects before and after intervention were compared. Results: After the intervention, the intervention group s skeletal muscle (22.90±3.63)kg, muscle mass (39.75±5.57)kg, lean body mass (41.52±6.79)kg, sitting arm support (49.19±35.28)s, standing timing test (22.13±6.01)s, half crunches (20.12±6.48), grip strength [left (15.98±4.86)kg; right (16.37±5.46)kg], heart rate immediately after 2 min stepping exercise (91.43±13.44)frequency/min, Standing on one foot with eyes closed [left (5.82±5.20)s; right (6.02±5.56)s] compared with before exercise, the body fat decreased(t=2.57,2.72,2.07,2.10,3.31,2.92,2.76,3.44, 2.86,2.04,2.38, -2.92,P<0.05); after the intervention, the sitting arm support and closed eyes standing(right) improved(P<0.05). Conclusion Aerobic combined resistance exercise can improve muscle strength and endurance, aerobic endurance and balance ability in adolescents with moderate mental retardation and adaptability of teenagers with moderate mental retardation.

Objective To examine the immunoregulation of Celastrus orbiculatus extracts(COE),a traditional Chinese medicine,on maturation and function of dendritic cells(DCs)in vitro and in vivo.Methods In vitro,after treated with COE indifferent nontoxic concentrations(0,10,20,40,80,and 160 μg/mL)for 5 d,the surface immunological molecules andcytokine secretion of mice bone marrow-derived DCs in response to COE were analyzed by flow cytometric analysis(FACS)and enzyme linked immunosorbent assay(ELISA),respectively.In vivo,mouse hepatoma cells(Hepal-6,1 ×106)were injected sc and were treated with different dosages of COE(10,20 or 40 mg/kg/d).Effects on tumor growth were determined by tumor volume and histology analysis after 28 d administration of COE.The relative proportions ofmature DCs and CD8+ T cells were measured in mononuclear cells that had been isolated from spleen by FACS.Results COE stimulated IL-2 and IFN-γ secretion of DCs,simultaneously enhanced the maturation of DCs byenhancing immunological molecule(CD40,CDS0,CD86,H-2Kb,and I-Ab)expression in a dose-dependent manner.Furthermore,the chcmotactic responses of DCs were significantly higher in COE-treated than untreated DCs,in association with higher chcmokine receptor 7 expression.Furthermore,COE increased DCs produce IFN-γ and IL-2 ina dose-dependent manner when the concentration of COE less than 40 μg/mL,decreased DCs produce IL-10 and IL-4also in a dose-dependent manner.In in vivo studies,COE can not only suppress growth of malignant hepatocellularcarcinomas but also stimulate maturation of DCs,associated with strongly enhanced CD8+ CTL responses.ConclusionThese data provide new insight into the mechanism of action of COE and indicate that the stimulation of maturation andfunction of DCs by COE contributes to its immunoregulatory effects.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.
