Objective: To investigate the association between brain and muscle Arnt like protein 1( BMAL 1) gene and ambulatory blood pressure (ABP) parameters in college students, and to explore the influence of the interaction between the gene and weight status on the ABP levels, so as to provide reference for early prevention of chronic cardiovascular diseases related to hypertension. Methods: During September 2022 to June 2024, a total of 510 college students were recruited from a university in Changsha, China for on site questionnaire investigation, physical examination, ABP monitoring and genotyping testing. Multiple linear regression method was used to explore the association between the BMAL 1 gene and ABP indicators. An interaction term was included in the general linear model of multiple linear regression to analyze the interactive effects of BMAL 1 gene polymorphisms and weight status on ABP levels. Results: The prevalence of abnormal 24 hour blood pressure, abnormal daytime blood pressure, and abnormal nighttime blood pressure were 3.3%, 3.1%, and 3.9%, respectively. Multiple linear regression analysis showed that the BMAL 1/rs7950226 polymorphism was positively correlated with the 24 hour diastolic blood pressure(DBP) and the daytime DBP level after adjusting for gender, age, and body mass index( β =0.87,0.99, both P <0.05). Also, interaction between BMAL 1/ rs 11022775 and weight status on the nighttime DBP level ( P interaction =0.03) was found. The CC genotype carriers had significantly higher nighttime DBP level ( β =3.52, P <0.05) among overweight/obesity college students, but no differences in nocturnal DBP levels were observed between CC genotype carriers and TT+CT genotype carriers among college students with normal body weight( P > 0.05). Conclusions The rs 7950226 polymorphism is associated with 24 hours DBP and daytime DBP levels. Significant interaction between rs 11022775 with weight status on the nighttime DBP level is found among college students.

Objective: To analyze the trends and influencing factors of endurance performance of 19-22 years old college students in Hunan Province from 1985 to 2019, so as to provide objective and scientific basis for sports and health work in colleges and universities. Methods: A retrospective analysis was conducted on the data of 14 490 college students aged 19-22 in Hunan Province from 8 consecutive National Student Physical Fitness and Health Surveys conducted from 1985 to 2019. The analysis indexes were 1 000 m running for boys and 800 m running for girls. Results: From 1985 to 2019, the endurance running time of 19-22 years old Han college students in Hunan Province showed an obvious trend of decline. The 1 000 m running time of urban and rural male students increased by 41.9 and 45.4 s on average, and the 800 m running time of urban and rural female students increased by 29.5 and 30.6 s on average, respectively. Multiple linear regression analysis showed that age ( β =0.17), urban students (rural students as reference; β =0.44), GDP ( β =0.94) and urbanization level ( β = 0.44 ) were positively correlated with the average endurance running time of males. Urban students ( β =0.92), GDP ( β = 1.38 ) and Engel coefficient ( β =0.93) were positively correlated with the average endurance running time of females. BMI ( β =-0.47) was negatively correlated with the females mean time of endurance running ( P ＜0.05). Conclusion The endurance performance of Han college students in Hunan Province showed a declining trend from 1985 to 2019,which is associated with age, urban and rural distribution, regional GDP, Engel s coefficient, urbanization level and BMI. Effective measures should be taken to improve the physical quality of college students.

Objective: To explore the gene lifestyle interaction of ATP2B1-eNOS pathway gene polymorphisms on blood pressure. Methods: Using the convenient cluster sampling method, a total of 872 junior middle school students from 3 school in July to August 2019, were included in the final analysis. The survey included questionnaire investigation, anthropometry measurement and blood sample collection. After DNA was extracted from peripheral blood samples, the gene polymorphisms ( ATP2B1 gene rs 17249754 and rs 2070759, eNOS gene rs 1799983 and rs 2070744) were genotyped. Logistic regression model was used to analyze the association between gene polymorphism and blood pressure phenotypes. Results: The prevalence of high blood pressure was 9.52 % in adolescents(9.15% in boys and 9.87% in girls),with no significant sex difference ( χ 2=0.13, P =0.72). There were statistically significant differences between boys and girls in age, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) classification, birth weight, daily school physical exercise time and daily playing video games time ( P <0.05). Logistic regression analysis showed that, eNOS gene rs 2070744 polymorphism was associated with high blood pressure (HBP) under the recessive model, and the risk of HBP in CC genotype carriers were higher than that TT/TC genotype carriers ( OR=3.88, 95%CI =1.00-15.02, P < 0.05 ). The results of gene lifestyle interaction showed that ATP2B1 gene rs 2070759 polymorphism gene had an interaction with the time of physical exercise in school ( P interaction =0.05). In the subgroup with daily physical exercise time at sch ool ＜1 hour , the TT/TG genotype carriers were associated with increased risk of HBP compared with GG genotype carriers( OR= 2.65 , 95%CI =1.11-6.30, P <0.05). But in the subgroup with daily physical exercise time in school ≥1 hour, rs 2070759 was not significantly associated with HBP. Conclusion eNOS/rs 2070744 polymorphisms are associated with risk of HBP among adolescents. There is significant interaction between ATP2B1 gene rs 2070759 polymorphism and physical exercise time in school on HBP. Adolescents should spend more time on physical activity in school, which will help to maintain normal blood pressure level.

Objective: To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) combined with donepezil on the cognition of persons with post-stroke cognitive impairment (PSCI) and their ability to perform activities of daily living (ADL). Methods: A total of 106 PSCI patients were randomly divided into an observation group and a control group using a random number table. Those in the observation group received 10Hz rTMS (5 seconds on and 25 seconds off for 20 minutes daily) and donepezil daily, 5 days per week for 4 weeks, while those in the control group were provided with donepezil but only sham rTMS on the same schedule. Before and after 4 weeks of treatment, the Montreal cognitive assessment scale (MoCA), the Rivermead behavior memory test (RBMT) and the modified Barthel index (MBI) were used to evaluate the subjects′ cognitive functioning, memory capacity and ADL ability. The latency and amplitude of auditory event-related potential P300 were also assessed using a myoelectric evoked potential apparatus. Results: After the treatment, improvement was observed in all the measurements of both groups. After the treatment, the average MoCA, RBMT and MBI scores, as well as the latency and amplitude of P300 in the observation group were all significantly better than among the control group. Conclusions rTMS can supplement donepezil′s ability to improve the cognition and ADL ability of persons with PSCI. Such therapy is worthy of clinical promotion and application.

Objective:To investigate the knowledge, attitudes and practices of medical staff rehabilitating COVID-19 survivors to provide references for related training.Methods:A questionnaire survey was administered in early March 2020 to 296 medical staff assessing their knowledge, attitudes, and practices in COVID-19 rehabilitation.Results:More than half of those surveyed received full marks on knowledge and attitudes, but only about 43% received full marks for their practices. Significant differences were found in the knowledge, attitude and practices scores among medical staff of different ages, with different numbers of years of training and working experience, with different professional titles, and in different departments.Conclusion:The COVID-19 rehabilitation knowledge and practices of a minority of the medical staff tested needed improving, and targeted training should be conducted.

[Abstract] Objective: To investigate the miRNAs that can intervene Mcl-1 expression in HBV-related liver cancers and to study their synergistic anti-cancer effect with sorafenib. Methods: The expressions of miR-29, miR-101 and miR-193b in HepG2.2.15 (HBV positive) and HepG2.vc (HBV negative) cells were detected by qPCR. miRNA mimics of low expressed genes in HepG2.2.15 cells were synthesized and transfected into HepG2.2.15 and HepG2.vc cells, respectively. qPCR was used to detect target miRNA expression. Western blotting was used to detect the expression of mcl-1 protein in cells before and after transfection.At the same time, (1×10-9)~(1× 10-3) mol/L of sorafenib was add to both transfected and non-transfected HepG2.2.15 and HepG2.vc cells; 72 h later, the IC50 and cell apoptosis was evaluated. Results: The expression of miR-193b in HepG2.2.15 cells was significantly lower than that in HepG2.2.15 cells (P <0.05). The expression of miR-193b in HepG2.2.15 cells and HepG2.2.15 cells was significantly higher after miR-193b mimics transfection (P <0.05). Compared with HepG2.vc cells, the expression of Mcl-1 protein in HepG2.2.15 cells was significantly increased (P <0.05). The expression of Mcl-1 protein in HepG2.2.15 and HepG2.vc cells was significantly decreased after miR-193b mimics transfection (P<0.05). After miR-193b mimics transfection, sorafenib could significantly increase apoptosis rate of both HepG2.2.15 and HepG2.vc cells. Conclusion: The low susceptibility of HBV-related liver cancer to sorafenib may be related with the low expression of miR-193b in cancer cells. Mcl-1 might be used as a target of miR-193b, and miR-193b mimics have a significant synergistic effect with sorafenib.

OBJECTIVETo observe the effect on post-stroke dysphagia treated with acupuncture of meridian differentiation.

METHODSOne hundred and thirty patients of post-stroke dysphagia were randomized into an observation group (67 cases) and a control group (63 cases). Conventional medication and rehabilitation training were applied in the two groups. In the observation group, acupuncture based on meridian differentiation was adopted. The main acupoints were Neiguan (PC 6), Shuigou (GV 26), Sanyinjiao (SP 6), Fengchi (GB 20), Lianquan (CV 23), Jialianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), etc. The supplementary points were selected according to different patterns/syndromes. In the control group, the points were selected 5 cm lateral to the acupoints used in the observation groups and stimulated with shallow puncture. The needles were retained for 30 min, once daily, 5 treatments a week and continuously for 6 weeks in the two groups. Separately, before treatment, in 6 weeks after treatment and in follow-up after 3 months, the standardized swallowing assessment (SSA), the video fluoroscopic swallowing study (VFSS), the modified Barthel index (MBI) and the swallowing related quality of life (SWAL-QOL) were observed in the two groups and the efficacy was assessed.

RESULTSIn 6 weeks of treatment, the scores of SSA, VFSS, MBI and SWAL-QOL were improved apparently as compared with those before treatment (<0.01,<0.05) in the patients of the two groups. The results in the observation group were better apparently than those in the control group (<0.01,<0.05). In follow-up after 3 months, the scores of SSA, MBI and SWAL-QOL were improved apparently as compared with those before treatment in thepatients of the two groups (all<0.01), in which, MBI score was improved apparently as compared with that in 6 weeks of treatment in the patients of the two groups (both<0.05). Those scores in the observation group were improved apparently as compared with those in the control group (<0.01,<0.05). In 6 weeks of treatment and in 3 months of follow-up, the effective rates in the observation group were 91.8% (56/61) and 93.4% (57/61), better than 80.0% (44/55) and 85.5% (47/55) in the control group separately, indicating the significant difference (both<0.05).

CONCLUSIONSThe acupuncture of meridian differentiation improves significantly swallowing function and survival quality in patients of stroke.

Objective To study the therapeutic effects of extracorporeal shock wave therapy (ESWT) on temporomandibular joint disorders (TMDs).Methods Sixty patients with a temporomandibular joint disorder were randomly divided into an ESWT group and a control group,each of 30.Both groups were given routine rehabilitation training,but the treatment group additionally received ESWT for 2 weeks.Fricton's index was used to evaluate temporomandibular joint function.The subjects used a visual analogue scale (VAS) to evaluate their pain levels.The SF-36 scale was applied to assess their life quality.Results After two weeks of treatment,the average assessment score and VAS score had decreased significantly in both groups.After treatment the average scores for mandibular movement,muscle palpation,joint noise and joint palpation,and the palpation,dysfunction and craniomandibular indexes were all significantly lower in the ESWT group than in the control group.Significant differences were also found in the average VAS scores and on the social functioning domain of the SF-36 between the ESWT group and the control group.Conclusion ESWT combined with rehabilitation training can significantly relieve the symptoms and pain of TMDs.

ObjectiveTo observe the effect of acupuncture plus rehabilitation training on the function recovery of patients with post-stroke depression.MethodNinety-eight patients with post-stroke depression were randomized into two groups to receive conventional management and anti-depressants. The control group was intervened by sham-acupuncture plus Fluoxetine tablets and comprehensive rehabilitation training, while the observation group was by acupuncture plus Fluoxetine tablets and comprehensive rehabilitation training. Prior to the intervention and after 8-week treatments, the depression state, motor function and activities of daily life (ADL) were evaluated by using Hamilton Depression Scale (HAMD), Fugl-Meyer Assessment (FMA) and Modified Barthel Index (MBI). The indexes and quality of life were also determined during the 3-month follow-up study.ResultBefore intervention, there were no significant differences in comparing HAMD, FMA and MBI scores (P>0.05). After 8-week treatment, the HAMD, FMA and MBI scores were significantlyimprovedin both groups (P<0.01,P<0.05). After treatment, the HAMD, FMA, and MBI scores in the observation group were significantlydifferent fromthat in the control group (P<0.01,P<0.05). The total effective rate was 90.0% in the observation group versus 79.2% in the control group, and the difference was statistically significant (P<0.05). The 3-month follow-up study showed significant differences in comparing the indexes between the two groups (P<0.05, P<0.01).ConclusionAcupuncture plus rehabilitation training benefits the improvement of depression state, motor function, cognitive function and quality of life in patients withpost-stroke depression, and is worth promotion.
