Objective: To explore the effects of cyclic training on metabolic syndrome among obese adolescents, so as to provide a reference for reducing physical burden and maintaining physical health for the obese adolescent population. Methods: The study selected 42 obese adolescents aged 10-17 from Foshan City from June 1 to September 1, 2021. The subjects were randomly divided into a training group (n=24) and a control group (n=18). The training group implemented a 12week training plan (4 times weekly), including two major events and six movements, namely resistance training (push ups, sit ups, forward lunge) and aerobic exercise (high leg lifts, stationary runs,jumping jack), and each action lasted for 25 seconds with a 15 second interval, completing 4 groups. The control group maintained daily living habits.The ttest and Chisquare test were used for statistical analysis. Results: After intervention, the weight, body mass index (BMI), body fat percentage and fat mass of the training group [(72.3±1.8)kg, (26.4±2.0)kg/m2, (31.9±2.3)%, (17.5±2.8)kg] were all lower than before intervention [(73.8±2.1)kg, (30.3±1.8)kg/m2, (34.4±2.5)%, (20.0±3.3)kg], and the muscle mass and physical fitness index of the training group [(32.4±1.1)kg, (67.3±5.3)%] were higher than before intervention [(31.5±1.5)kg, (63.1±6.9)%] (t=-2.75，-7.10，-3.61，-2.83,2.37,2.36, P<0.05). After intervention, the blood glucose, cholesterol, lowdensity lipoprotein cholesterol , waist circumference and hip circumference of the training group [(4.6±0.5)mmol/L, (8.2±0.4)mmol/L, (2.8±1.2)mmol/L, (73.5±4.2)cm, (93.2±5.8)cm] were all lower than those before intervention [(4.9±0.4)mmol/L, (8.7±0.8)mmol/L, (3.9±1.1)mmol/L, (77.8±3.9)cm, (99.5±5.1)cm], and highdensity lipoprotein cholesterol was higher than that before intervention[(3.2±0.3)mmol/L,(2.9±0.8)mmol/L](t=-2.30,-2.74,-3.31,-3.68,-4.00,2.29, P<0.05). There was no statistically significant differences between groups in the parameters of each indicator before intervention (P>0.05), while all indicators in the training group were lower than those in the control group except for muscle mass, physical fitness index and highdensity lipoprotein cholesterol, which were higher than those in the control group after intervention (P<0.05). Conclusions The cyclic training method for 12 weeks is helpful to prevent the metabolic syndrome disease in obese adolescents.It is possible to appropriately increase the intervention methods of cyclic training to reduce the occurrence of metabolic syndrome among obese adolescents.

Long noncoding RNAs (lncRNAs) play a critical role in the regulation of atherosclerosis. Here, we investigated the role of the lncRNA growth arrest-specific 5 (lncR-GAS5) in atherogenesis. We found that the enforced expression of lncR-GAS5 contributed to the development of atherosclerosis, which presented as increased plaque size and reduced collagen content. Moreover, impaired autophagy was observed, as shown by a decreased LC3II/LC3I protein ratio and an elevated P62 level in lncR-GAS5-overexpressing human aortic endothelial cells. By contrast, lncR-GAS5 knockdown promoted autophagy. Moreover, serine/arginine-rich splicing factor 10 (SRSF10) knockdown increased the LC3II/LC3I ratio and decreased the P62 level, thus enhancing the formation of autophagic vacuoles, autolysosomes, and autophagosomes. Mechanistically, lncR-GAS5 regulated the downstream splicing factor SRSF10 to impair autophagy in the endothelium, which was reversed by the knockdown of SRSF10. Further results revealed that overexpression of the lncR-GAS5-targeted gene miR-193-5p promoted autophagy and autophagic vacuole accumulation by repressing its direct target gene, SRSF10. Notably, miR-193-5p overexpression decreased plaque size and increased collagen content. Altogether, these findings demonstrate that lncR-GAS5 partially contributes to atherogenesis and plaque instability by impairing endothelial autophagy. In conclusion, lncR-GAS5 overexpression arrested endothelial autophagy through the miR-193-5p/SRSF10 signaling pathway. Thus, miR-193-5p/SRSF10 may serve as a novel treatment target for atherosclerosis.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.

Objective:To analyze the health literacy level among medical staff and its influencing factors.Methods:Using the convenient sampling method, the in-service medical staff from four medical institutions (Shanghai Pudong New Area People′s Hospital, Shanghai Pudong New Area Zhoupu Hospital, Shanghai Tenth People′s Hospital Chongming Branch, and Shanghai Jing′an District Zhabei Central Hospital) were administered with a national residents′ health literacy questionnaire uniformly compiled by the China Health Education Center, and an electronic questionnaire independently compiled in combination with professional characteristics of the medical staff. The survey period was January 5-17, 2021. The contents of the questionnaire included basic information regarding gender, age, education, and professional title. Respondents were also asked whether they had chronic diseases, and three aspects of health literacy for basic knowledge and concepts, healthy lifestyle and behavior and health skills covering six other types of health problems including scientific outlook on health, infectious disease prevention and control literacy, chronic disease prevention and control. Safety and first aid literacy, basic medical literacy, health information literacy were also assessed. The total score for the questionnaire was 100 points. Respondents with a score of 80 or more were considered to have a competent health literacy. A total of 870 questionnaires were distributed, excluding incomplete ones, 826 valid questionnaires were used for analysis. Logistic regression was used to analyze factors influencing the health literacy among medical staff.Results:The overall health literacy level of medical staff was 64.0%, with 79.7% of respondents indicating that they had basic knowledge and concepts, 70.8% indicating that they practiced healthy lifestyles and behaviors, and 33.5% showed proficiencies in terms of health skills. From high to low, the health literacy levels for the six types of health problems were safety and first aid literacy (80.5%), scientific outlook on health (76.4%), infectious disease prevention and control literacy (60.2%), chronic disease prevention and control literacy (70.9%), basic medical literacy (52.7%), and health information literacy (50.2%). The results of a multivariate logistic regression analysis showed that physical condition, a lifestyle harmful to one′s health, highest educational background, and a professional title in the previous year were the independent influencing factors related to health literacy ( P<0.05). Conclusion:Levels of health skills, basic medical literacy, and health information literacy among medical staff are low, and physical condition in the previous year, lifestyle, professional title, and education are important factors influencing the level of health literacy among medical staff.

Objective:To evaluate the skin development and repair process of X-ray radiation damage in rat with non-invasive two-photon excitation fluorescence (TPEF) imaging technology in vivo. Methods:Totally 24 SD rats were randomly divided into four groups including X-ray irradiated group (25, 35 and 45 Gy) and non-irradiation control group. At different times after irradiation, the degree of skin injury was evaluated, and the pathological changes of nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] and collagen fiber fluorescence signals in epidermal cells were detected in vivo by TPEF imaging technology. Results:At 10 d post-irradiation, the skin of irradiation groups showed erythema and desquamation. At 15-20 d post-irradiation, the skin of radiation groups developed progressive exudation, edema and ulcers with increasing radiation dose. On day 25, the skin began to repair in the 25 Gy group, however, the skin of other groups still had exudation and ulcers. On day 10, NAD(P)H fluorescence signal in epidermal cells of irradiation groups decreased and the fluorescence signal of collagen fibers in papillary layer and reticular layer of irradiation groups reduced, which were significantly lower than that of normal control group ( t=24.145, 28.303, 26.989, 6.654, 7.510, 7.997, P<0.05). On day 30, fluorescence signal of NAD(P)H and collagen fibers in epidermal cells and dermis began to repair, the cell from stratum granulosum, stratum spinosum, and stratum basale in the 25 Gy group showed fluorescence signal, the other groups did not show. The fluorescence signal of collagen fibers in the 25 Gy group were gradually increased in papillary layer and reticular layer, however, they were significantly lower than normal control group ( t=115.133, 17.431, P<0.05), the skin of 45 Gy group did not show fluorescence signal of collagen fibers. Conclusions:The damage and repair process of epidermal cells and dermal collagen fiber can be detected noninvasively by TPEF imaging technology after X-ray irradiation in vivo.
