Thefive elements theory provides us a system classification of all things so we can do the research in a much reasonable way. Further more, our bodies are full of complicated bio-chemical reactions and thefive elements theory should also be applicable to those reaction systems. This paper will try to make use of thefive elements theory to carry on an innovative classification of different types of bio-chemical reactions with the help of the former foundation of related researches, to make the complicated bio-chemical reactions easy to understand, and point out that this kind of lately academic thought is of great significance to the medicine researches as well as the integrated traditional Chinese and western medicine.

The Six Meridians inTreatise on Exogenous Febrile Diseases were once thought the same with the six meridians ofThe Inner Canon of Huangdi. With this theory was overthrown, similarities and differences and the correlation between them have gradually been studied. In this paper, we take the Taiyang Median as an example to explain the similarities and differences from two aspects, including clinical symptoms and the understanding of the same disease with different treatment.

Objective: To understand the potential categories of harmful behaviors of college students in Wuling Mountain Area and its relationship with campus bullying, so as to provide a theoretical basis for promoting the development of college students physical and mental health. Methods: The stratified random cluster sampling method was used to select 3 042 college students from six universities in Wuling Mountain Area from October to December, 2022. The "Chinese Youth Health Related/Risk Behaviors Questionnaire" (University Edition) compiled by the National Youth Health Related/Risk Behaviors Survey Group was used to investigate the health risk behaviors. The potential category analysis method was used to analyze the food preference, insecurity, fighting, loneliness, depression, insomnia, heartbreak, suicidal ideation, smoking, drinking, game addiction, Internet addiction of health risk behaviors were used to further analyze the relationship between different categories and campus bullying by using multi category Logistic regression method. Results: College students in Wuling Mountain Area were classified into low risk group of category 1 (44.2%), category 2 (5.4%) substance dependent group, category 3(50.4%) emotional disorder group. The distribution of potential categories of health risk behaviors among college students was statistically significant by gender( χ 2=31.44, 11.69， P < 0.05 ). Logistic regression analysis showed that after controlling demographic variables, campus bullying was the risk factor of category 3 emotional disorder group( OR =1.88, P <0.01). Conclusion bullying. Colleges and universities should attach great importance to the occurrence of campus bullying, formulate intervention programs for different categories of health hazard behaviors, and promote the healthy development of college students physical and mental health.

Objective: To understand the potential categories of health risk behaviors among adolescents in the Wuling Mountain Area and their association with school connectedness, so as to provide reference for formulating classified and effective intervention measures. Methods: From March to June 2023, 3 386 middle and high school students from eight schools in the Wuling Mountain Area were selected using the multistage stratified cluster random sampling method. A basic information questionnaire, health risk behaviors questionnaire, and school connectedness scale were utilized for the survey. The latent classes of adolescent health risk behaviors in the Wuling Mountain Area were investigated by using latent class analysis, while an multinomial Logistic regression model was employed to analyze the association between latent classes and school connectedness. Results: Adolescent health risk behaviors in the Wuling Mountains Area were classified into three latent classes: high risk class of episodic behaviors ( 5.64 %), high risk class of implicit behaviors (26.90%), and low risk class of implicit behaviors (67.45%). Gender, ethnicity, and family type revealed significant differences in the distribution of the three latent classes ( χ 2=117.91, 22.55, 21.51, P <0.05). The results of the regression model analysis showed that, with the low risk class as the reference category, high school connectedness scores were associated with the high risk class of episodic behaviors ( OR=0.89, 95%CI = 0.88- 0.91) and the high risk class of implicit behaviors ( OR=0.90, 95%CI =0.89-0.91)( P <0.05). Conclusions The characteristics of adolescent health risk behavior classes in the Wuling Mountain Area are obvious. The high risk class of episodic behaviors and the high risk class of implicit behaviors are negatively correlated with school connectedness. Corresponding measures should be taken to enhance adolescents sense of belonging in school and reduce the aggregation and co occurrence of health risk behaviors.

Objective:To evaluate the intelligent performance measurement system for colonoscopy.Methods:Nine endoscopists from Renmin Hospital of Wuhan University were randomly assigned to the quality control group and the control group based on inclusion and exclusion criteria by the random number table. In the pre-quality-control stage (from April 20, 2019 to May 30, 2019), colonoscopic data acquired by the enrolled endoscopists were collected. In the training stage (June 1-30, 2019), the quality control group was trained on the quality control knowledge and the use of intelligent gastrointestinal endoscopy performance measurement system; but the control group was only trained on the quality control knowledge.In the post-quality-control stage (from July 1, 2019 to August 20, 2019), a weekly quality feedback was given to endoscopists of the quality control group, while the endoscopists of the control group had no quality control report.Then, the colonoscopic data acquired by enrolled endoscopists were prospectively collected during the period. The primary endpoint was adenoma detection rate. The secondary endpoints were withdrawal time, polyp detection rate and cecal intubation rate.Results:Four endoscopists were assigned to the quality control group and five to the control group. A total of 1 471 colonoscopic procedures were analyzed. The detection rates of adenoma and polyp in the quality control group increased with feedbacks[13.7% (45/329) VS 7.1% (24/338), χ2=55.796, P<0.001; 48.9% (161/329) VS 40.2% (136/338), χ2=4.071, P=0.044], while there were no significant differences in the control group [9.3% (37/398) VS 9.1% (37/406), χ2=0.329, P=0.566; 33.9% (135/398) VS 33.0% (134/496), χ2=3.616, P=0.057]. The withdrawal time in the quality control group increased with feedbacks[5.9 (3.9, 7.3) min VS 4.1 (2.8, 6.1) min, Z=6.965, P<0.001], while there was no significant difference in this variable in the control group [3.9 (2.7, 6.1) min VS 3.6 (2.6, 5.8) min, Z=1.355, P=0.175]. Conclusion:The intelligent performance measurement system for gastrointestinal endoscopy with feedbacks can monitor and improve the colonoscopic quality.

Objective: To understand the association between non suicidal self injury and self control among rural junior high school students in Guizhou Province, and to provide reference for the development of prevention and control measures. Methods: Using a multistage stratified random cluster sampling method, a questionnaire survey was administered to 4 452 junior high school students in 30 rural schools in Guizhou Province from November to December 2021 to investigate non suicidal self injury and self control using the Non suicidal Self Injury Scale and the Self Control Scale. Results: A total of 986 (22.2%) students had occasional non suicidal self injurious behaviors, 593 (13.3%) students reported frequent non suicidal self injury, and the occurrence of non suicidal self injury among junior high school students varied significantly by gender, grade, only child, residence, left behind experiences, academic performance, academic pressure, parent child relationship, peer relationship, teacher student relationship, and exposure to domestic violence ( χ 2=6.97-168.68, P <0.05); the average score of self control among junior high school students in rural Guizhou Province was 48.0 (39.0, 57.0), and the differences in self control scores, impulse control, healthy habits, resist temptation, focus on work, and moderate entertainment were of statistical significance among students with varied frequency of self injurious behavior ( Z=612.08, 464.64, 193.10, 228.86, 194.04 , 542.20, P <0.05); high self control score was associated with more non suicidal self injurious behavior ( OR=1.06, 95%CI=1.05-1.07, P <0.05). Conclusion The prevalence of non suicidal self injury is high among rural junior high school students in Guizhou province, and self control shows a predictive effect on non suicidal self injurious behavior.Schools, families and relevant government departments should pay full attention to it and formulate targeted prevention and control measures.

Objective: To explore the causal relationship between adolescent school connectedness and the co-occurrence with health risk behaviors among junior high school students, so as to provide the reference for reducing the occurrence of adolescents health risk behaviors among junior high school students. Methods: A total of 924 students from two junior high schools in Jishou City were selected by the convenience sampling and cluster sampling methods, and two follow up surveys were conducted at 6 month intervals in April (T1) and October (T2) of 2023 using the Adolescent Health Risk Behavior Questionnaire and the School Connection Scale. The scores of the co-occurrence of school connectedness and health risk behaviors among junior high school students were compared by different survey periods and genders using the t-test, and cross lagged analyses were performed using Mplus 8.3 software. Results: School connectedness scores among junior high school students in T1 and T2 surveys were (38.86±7.46) (37.87± 7.71 ) and co-occurrence of health risk behaviors scores were (1.64±0.68) (1.83±0.53), respectively, and the differences between the scores of the 2 surveys were statistically significant ( t=4.24, -4.14, P <0.05). The correlation between school connectedness and co-occurrence of health risk behaviors were statistically significant in both surveys ( r =-0.46 to -0.33, P <0.05). Cross lagged analyses showed that school connectedness in T1 negatively predicted the co-occurrence of health risk behaviors in T2 ( β =-0.08), and the co-occurrence of health risk behaviors in T1 negatively predicted the school connectedness in T2 ( β =-0.15) ( P <0.05). Conclusions There is a longitudinal causal relationship between school connectedness and co-occurrence of health risk behaviors among junior high school students. School connectedness should be improved through various ways to reduce the co-occurrence of health risk behaviors.
