Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) are considered as the lower He-sea points, which are located along the leg lines of stomach meridian of foot Yangming from top to bottom. According to the corresponding zang-fu of lower He-sea points, the distribution order from top to bottom is stomach, large intestine and small intestine. This is significantly different from digestive physiology function sequence of stomach, small intestine and large intestine in modern medicine. However, it conforms to their anatomical position from top to bottom. In order to make a further confirmation that the indication specificity of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is closely associated with anatomical location, a great number of ancient and modern literature is reviewed. It is found that the functions of the three acupoints are obviously related to stomach, large intestine and small intestine, respectively, indicating that the sequence of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is related to anatomical position of corresponding zang-fu. This study conclusion could play an important role for exploring the significance of anatomical location in indication specificity of acupoints.

Background and purpose:miRNA plays important roles in tumorigenesis. It has been reported that many kinds of serum miRNA serve as markers for tumor diagnosis and screening. This study aimed to detect the expression of serum miRNA-31 (miR-31) in colorectal cancer patients and to explore the effect of miR-31 on cell proliferation, apoptosis and cell cycle distribution. Methods: The expressions of miR-31 in 40 cases of colorectal cancer serum and 35 cases of the healthy control were examined by real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR). The correlation between miR-31 expression and clinicopathological features of colorectal cancer (including age, gender, depth of inifltration, lymph node metastasis, clinical stage) were further analyzed. The miR-31 mimics, inhibitor and miR-control (negative control) were transfected into HCT116 cells. The effect of miR-31 on cell proliferation was evaluated by CCK-8 method. Flow cytometry was used to examine the change of cell apoptosis and cell cycle. Results:Relative expression of serum miR-31 was signiifcantly increased in cancer patients compared with healthy controls (P<0.01). Expression of serum miR-31 was higher in poorly differentiated carcinoma than that in well or moderately differentiated carcinoma (P<0.05). No correlation was found between serum miR-31 expression and other clinicopathological variables. CCK-8 assay showed that after transfection with miR-31 mimics, the cell proliferation was increased, compared with miR-31 inhibitor and negative control group. Meantime, the apoptotic cell number was signiifcantly decreased, particularly in late apoptosis. The cell number of G1 stage was remarkably increased in miR-31 inhibitor group, compared with miR-31mimics and negative control group. Conclusion:The expression of serum miR-31 is higher in colorectal cancer. miR-31 can promote cell proliferation and inhibit the apoptosis of HCT116 cells. It might be a potential biomarker for colorectal cancer.

Objective: To establish a risk assessment index system for epidemic infectious diseases in primary and secondary schools, for early warning and prevention of school infectious diseases accurately and timely. Methods: Through literature review, the indicators pool was established by consulting relevant experts and referring to practical experience. Then two rounds of expert consultation using the Delphi method were conducted(13 experts of round 1, and 20 experts of round 2). The concentration of expert opinions (the average, the percentage of full marks) and the coordination of expert opinions (the coefficient of variation, the coordination coefficient W ) were calculated and analyzed. The coordination coefficient W was obtained by nonparametric Kendall s W test of multiple samples. According to the experts feedback, necessary addition, reduction and modification of the indicators were carried out to determine the evaluation index system, and the analytic hierarchy process (AHP) was used to calculate the weight of each indicator. Results: The expert authority coefficients of the two rounds of consultation were 0.89 and 0.88, respectively, and the form recovery rate was 100%. The range of the variation coefficient of each three level indicator was 0.07-0.31 and 0.06-0.19, and the coordination coefficient W was 0.25 and 0.47, respectively, indicating that the consistency and credibility of expert opinions were good. Finally, the risk assessment index system of infectious diseases in primary and secondary schools was established, which was composed of 5 first level indexes, 23 second level indexes and 86 third level indexes. The AHP was used to calculate the intra level weight of the index. The variation coefficient of five first level indicators of school health management and security system, school health personnel facilities, health monitoring and cognition level, severity and coping measures were 0.09, 0.06, 0.08, 0.12 and 0.06 , respectively, and the weight coefficients were 20.42%, 21.19%, 19.87%, 17.45% and 21.08%, respectively. Conclusion The risk assessment index system of school infectious diseases is applicable to primary and secondary schools. The initiative, coordination and authority of experts in this system are all high. It is of practical guiding significance for the early warning of infectious diseases in primary and secondary schools.

Objective: To investigate incidence of traffic injury and its associated factors among secondary school students in Shanghai, so as to provide scientific basis for intervention. Methods: Using the method of multi stage stratified random cluster sampling, an on-the-spot anonymous questionnaire survey was conducted among 19 629 adolescents from 16 districts in Shanghai from May to June 2021. The multivariate Logistic regression was used to analyze possible associated factors. Results: The rate of road traffic injuries among secondary school students in Shanghai was 0.74%, the highest reporting rate among secondary vocational school students (1.35%), followed by junior high school students (0.72%), and the lowest reporting rate of road traffic injuries among senior high school students (0.55%), with statistically significant differences ( χ 2=13.39, P <0.01). The results of multivariate Logistic regression analysis showed that the junior high school ( OR =0.56, 95% CI =0.35-0.89) or senior high school ( OR = 0.40 , 95% CI =0.24-0.68) and residential school ( OR =0.39, 95% CI =0.18-0.88) were protective factors of road traffic injuries( P <0.05). Male ( OR =1.65, 95% CI =1.14-2.37), unaware of seat belt ( OR =6.38, 95% CI =2.81-14.50), had a cycling chase/fight ( OR =2.33, 95% CI =1.39-3.90), music or phone calls on a bicycle ( OR =2.54, 95% CI =1.72-3.75) were positively correlated with road traffic injury( P <0.05). Conclusions The road traffic injury among secondary school students in Shanghai is related to many factors, and traffic hazards are common among students in all school sections. Targeted measures should be taken to strengthen traffic safety knowledge education and intervention in healthy behaviors among adolescents, in order to reduce the incidence of road traffic injury.

Objective: To explore the association between dietary behaviors and sleep duration among middle school students in Shanghai, so as to provide reference for interventions targeting insufficient sleep. Methods: From May to June 2021, a stratified cluster random sampling method was employed to select a sample of 10-17yearold middle school students for monitoring their healthrisk behaviors. A total of 5 538 valid questionnaires were collected. The survey included items such as daily sleep duration, weekly consumption of sugary beverages, freshly squeezed fruit juice, fresh fruits, fresh vegetables, fried foods, milk and yogurt, breakfast habits, and frequency of eating outside. Statistical analysis was conducted using Chisquare test, Wilcoxon ranksum test, and multivariable Logistic regression model. Results: About 73.7% of middle school students reported insufficient sleep in Shanghai. There was a positive correlation between the average daily consumption of fresh fruits and breakfast consumption with sleep duration. In other words, a higher frequency of consuming fresh fruits (OR=1.29) and eating breakfast (OR=1.07) were associated with a higher likelihood of sufficient sleep. Conversely, there was a negative correlation between the frequency of consuming desserts (OR=0.78) and fried foods (OR=0.88) and sleep duration (P<0.05). Conclusions Increasing the consumption of fresh fruits and maintaining regular breakfast habits while reducing the intake of fried foods can contribute to achieving sufficient sleep among middle school students. When implementing interventions to improve sleep among middle school students, promoting healthy and balanced diets can be considered as one of the intervention strategies.

Objective: To elucidate the association between biorhythm disorders and health risk behaviors in adolescence, so as to provide reference for appropriate interventions. Methods: From March to April 2023, 2 381 adolescents in Shanghai were selected as research objects using convenience sampling and stratified random cluster sampling methods. The Self rating Questionnaire of Biological Rhythm Disorders for Adolescents (SQBRDA) and the self report health risk behaviors questionnaire were used to investigate the status of adolescent biorhythm disorders and nine kinds of health risk behaviors, while a multivariate Logistic regression model was employed to analyze the association between the two variables. Results: The average SQBRDA score was (68.25±0.42) The incidence and detection rates of health risk behaviors in the groups with no co occurrence, mild co occurrence, moderate co occurrence, and severe co occurrence were 234(9.83%), 1 176(49.39%), 830(34.86%) and 141(5.92%), respectively. The total SQBRDA score was positively correlated with the risk of co occurrence of health risk behaviors. The risk of mild co occurrence, moderate co occurrence, and severe co occurrence of health risk behaviors was 9.05 times (95% CI =4.25-19.15, P <0.01), 44.55 times (95% CI =20.75-96.05, P <0.01) and 110.05 times (95% CI =40.65-297.95, P <0.01) higher, respectively, among adolescents with higher scores of biorhythm disorders compared to adolescents with lower scores of biorhythm disorders. Conclusions Health risk behaviors among adolescents in Shanghai draw attention to a serious phenomenon whereby biorhythm disorders are positively correlated with the risk of co occurrence. Comprehensive interventions aimed at addressing adolescent health risk behaviors should focus on regulating biorhythm disorders.

Background The correlation between depression and sleep quality is well established in adults, but similar evidence is lacking in adolescents. Objective To study the sleep quality, the positive rate of depressive symptoms, and their correlation among middle school students in Shanghai, so as to provide a basis for providing mental health and sleep management to this group of students. Methods From September to November 2020, using multi-stage stratified cluster random sampling method, a total of 7796 students from 32 middle schools in 16 districts of Shanghai were selected to conduct a questionnaire survey. The questionnaire for middle school students of the 2020 Shanghai Students’ Common Diseases and Health Influencing Factors Surveillance was used to collect students' demographic information, history of smoking, history of drinking, and history of chronic diseases; the Pittsburgh Sleep Quality Index was used to assess sleep quality; and the Center for Epidemiological Studies Depression Scale was used to evaluate depressive symptoms. χ² test was used to compare qualitative data between groups. Binary logistic regression was used to analyze the correlation between sleep quality and depressive symptoms among middle school students in Shanghai. Results After excluding incomplete questionnaires, a total of 7160 valid questionnaires were collected. The average sleep time of middle school students in Shanghai was (7.54±1.15) h. Among them, 84.8% reported insufficient sleep time < 9 h, and only 15.2% reported sleep time ≥9 h. In addition, 9.2% of the students had poor sleep quality (Pittsburgh Sleep Quality Index ≥8 points). The sleep quality of urban students was worse than that of suburban students. The sleep quality of girls was worse than that of boys. The sleep quality of students in the third grade of middle school was worse than that of students in the first and second grades of middle school. Students with smoking history, drinking history, and chronic disease history had worse sleep quality than those without (P<0.05). The positive rate of depressive symptoms among middle school students in Shanghai was 22.2%, among which 7.0% reported possible depressive symptoms and 15.2% reported definite depressive symptoms. The positive rate of depressive symptoms in female students (26.1%) was higher than that in male students (18.5%); among different grades of middle school, the positive rate of depressive symptoms of the third grade middle school students was the highest (24.1%); the positive rates of depressive symptoms in students with smoking history, drinking history, and chronic disease history were higher than those without; the positive rate of depressive symptoms was higher in students with poor sleep quality (P<0.05). The results of logistic regression analysis indicated that the students with poor sleep quality showed higher risks of reporting depressive symptoms, and the OR (95%CI) was 17.064 (14.024-20.764). Conclusion The positive rates of poor sleep quality and depressive symptoms of middle school students in Shanghai are high, and there is a significant correlation between these two indicators. For students’ mental health and sleep management, more attention should be paid to the quality in addition to the quantity of sleep.
