ABSTRACT
Objective:To evaluate the influence of depression and anxiety on sleep quality, and to provide a basis for preventing sleep disorders in community-dwelling older adults.Methods:Cluster sampling was used.A self-designed questionnaire, the Pittsburgh Sleep Quality Index(PSQI), the Patient Health Questionnaire-9(PHQ-9), and the Generalized Anxiety Disorder Questionnaire-7(GAD-7)were used for the survey.The sleep quality and the influence of depression and anxiety on sleep quality of 955 community-dwelling older adults aged 60 and above were investigated.Results:The detection rate of sleep disorders, depression and anxiety were 24.5%, 19.1% and 14.3%, respectively.There was a positive correlation between sleep quality scores(including the total score and the scores of each dimension)and the anxiety and depression scores( rs: 0.115-0.558, P<0.01 for all). After adjusting for possible confounding effects of gender, age, food intake or tea drinking before bed, Logistic regression analysis showed that the presence of depression( OR=3.555, 95% CI: 2.235-5.653, P<0.05)and anxiety( OR=1.812, 95% CI: 1.070-3.070, P<0.05)were significantly related to sleep disorders in the elderly.The multivariate adjusted population attributable risk of depression and anxiety for sleep disorders in the elderly was 32.56% and 16.09%, respectively.The presence of depression and anxiety were associated with 38.87% of the population attributable risk for sleep disorders. Conclusions:Depression and anxiety are important risk factors for sleep disorders in the elderly.Strengthening the identification and intervention of depression and anxiety is beneficial to improve the sleep quality of elderly living in the community.
ABSTRACT
Novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) is spreading rapidly around the world and has become a global pandemic. Meteorological factors have been recognized as one of the critical factors that influence the epidemiology and transmission of infectious diseases. In this context, the World Meteorological Organization and scholars at home and abroad have paid extensive attention to the relationships of environment and meteorology with COVID-19. This paper systematically collected and sorted out relevant domestic and foreign studies, and reviewed the latest research progress on the impact of environmental and meteorological factors on COVID-19, classifying them into typical meteorological factors (such as temperature, humidity, and wind speed), local environmental factors (such as indoor enclosed environment, ventilation, disinfection, and air conditioning), and air pollution. Current research evidence suggests that typical meteorological factors, local environmental factors, and air pollutants are closely related to the transmission of COVID-19. However, the results of different studies are still divergent due to uncertainty about the influencing mechanism, and differences in research areas and methods. This review elucidated the importance of environmental and meteorological factors to the spread of COVID-19, and provided useful implications for the control of further large-scale transmission of COVID-19 and the development of prevention and control strategies under different environmental and meteorological conditions.
ABSTRACT
Objective:To test the HIV virus nucleic acid using immunoblot method (Western blotting, WB) and to follow-up with the negative and indeterminate samples in the Dujiangyan area, compare the WB and nucleic acid results before and after followed-up, and try to reduce the WB band′s false-negatives and false-positives.Methods:The 286 suspected HIV infection samples in the Dujiangyan region from January to October 2021 were confirmed by WB, the HIV virus load were tested for the samples that were WB negative and WB indeterminate, those patients were followed-up with epidemiological history and viral load results, and the results before and after tracking were compared.Results:In the 286 samples of suspected HIV infection included in this study, we reported 213 (74.48%) WB positive, 37 WB negative (12.94%), and 36 WB indeterminate (12.58%); 10 of 37 WB negative samples were followed-up; 18 of 36 WB indeterminate samples were followed-up. Among the followed-up WB negative and indeterminate samples, 17 of them had virus nucleic acid detection prior to the follow-up, and all of them turned positive after following-up. The others with no previous virus nucleic acid detection were confirmed to be negative.Conclusions:Among the followed-up samples, 2 samples were false-negative in WB negative results, and 3 were false-positive in WB indeterminate results. The viral nucleic acid must be tested and followed-up in WB negative and indeterminate samples.

ABSTRACT
Objective@#To examine the impact of physical intelligence teaching on the function of children s sensory integration, so as to provide reference for promoting the development of sensory integration system.@*Methods@#From February to May 2023, the intervention was implemented for 12 weeks among 136 children aged 4-5 (68 in the intervention group and 68 in the control group). The intervention group received situational and game based physical intelligence teaching, the control group received sports game teaching according to the original curriculum objectives of the kindergarten. Intervention was administered 3 times a week for 40 minutes each time. The sensory integration ability of the intervention group and the control group were evaluated before and after the intervention with Chi square test and t test.@*Results@#The vestibular sensation, proprioception and tactile sensation of between boys and girls in the intervention group were significantly improved compared with before intervention (boys:44.14±11.52 vs. 53.34± 9.49 ,44.57±12.76 vs. 50.54±11.86,49.31±12.18 vs. 55.00±10.24,girls:46.00±11.01 vs. 54.58±10.06,48.79±13.17 vs. 53.64±11.97,52.67±11.67 vs. 56.91±10.42, t =-3.24,-2.49,-2.09,-5.24,-12.94,-2.56, P <0.05). There was no significant difference in vestibular sensation between boys and girls in the control group (boys:45.91±11.66 vs. 46.31± 11.20,girls:48.27±13.56 vs. 48.45 ±13.54, t =-0.87,-0.07, P >0.05), but there was a significant improvement in proprioception and tactile sensation in both boys and girls (boys:46.63±11.76 vs. 48.06±11.69,51.63±11.98 vs. 52.40±12.18,girls:50.45±12.16 vs. 51.67± 12.03 ,53.36±12.48 vs. 54.39±12.57, t =-3.36,-2.08,-4.66,-2.86, P <0.05). After the intervention, compared with the control group, the vestibular sensation of both boys and girls significantly improved ( t=2.83, 2.08, P <0.05), with exception of proprioception and tactile sensation ( t =0.88,0.67,0.97,0.88, P >0.05). In the experimental group, the number of normal boys increased from 12 to 24, while the number of dysfunctional boys decreased from 23 to 11, with a statistically significant difference ( χ 2=11.53, P <0.01). There was no statistically significant difference in sensory integration in boys of the control group before and after the experiment ( χ 2= 1.10 , P >0.05). After intervention,the number of normal girls in the experimental group increased from 15 to 27, while the number of dysfunctional girls decreased from 18 to 6, with a statistically significant difference ( χ 2=10.39, P < 0.05 ). There was no statistically significant difference in sensory integration in girls from the control group before and after the experiment ( χ 2=2.08, P > 0.05 ).@*Conclusion@#Physical intelligence teaching can effectively improve children s sensory integration ability, especially for vestibular function.

ABSTRACT
Objective:The study was to investigate the effects of epidermal growth factor receptor (EGFR) antibody (cetuximab,C225) combined with cyclooxygenase 2(COX-2)inhibitor (nimesulide) on the proliferation and apoptosis of colon cancer HT-29 cells, and explore the potential molecular mechanism. Methods:C225 and nimesulide alone or in combination were incubated with HT-29 cells. MTT assay was used to measure the cell proliferation. AO/EB staining and flow cytometry were used to measure the cell apoptosis. RT-PCR was used to detect the COX-2 and non steroidal anti-inflammatory drug-activated gene (NAG-1) mRNA expression levels. The expression of Akt and phosphor-Akt protein was examined by Western blotting. Results:The inhibitory effect of nimesulide combined with C225 was significantly stronger than that of nimesulide alone [(72.8±2.3)% vs (51.8±1.8)% , P<0.05]at 48 h. Typical changes of apoptosis in HT-29 cells were observed in nimesulide combined with C225 treatment group. The apoptosis rate of combined group was significantly higher than that of single nimesulide group [(57.67±0.86)% vs(33.27±1.47)%]and single C225 group [(6.27±0.55)%,P<0.05]. C225 down-regulated the expression of COX-2 mRNA. The expression of NAG-1 mRNA was up-regulated in all treatment groups and the expression of phosphor-Akt was significantly down-regulated in combined treatment group than single nimesulide or C225 group. Conclusion:Nimesulide combined with C225 has obvious synergistic effects in inducing apoptosis. The potential mechanisms may be that EGFR signaling pathway is involved in the regulation of cycloxygenase-2 expression in HT-29 cells and finally influence the proliferation and apoptosis of HT-29 cells through the up-regulation of NAG-1 and down-regulation of phosphor-Akt expression.
