Objective: To explore the beneficial regulatory effect of mild moxibustion from different distances at Zusanli (ST 36) of healthy population on the functions of temperature-related brain regions. Methods: In 20 recruited healthy subjects, the change of the temperature-related brain regions induced by mild moxibustion from different distances at Zusanli (ST 36) was observed by functional magnetic resonance imaging (fMRI). Results: In comparison of the values in amplitude of low-frequency fluctuation (fALFF) during and before moxibustion, it has been found that in moxibustion of 2 cm distance, fALFF value increased in the brain regions of the left anterior cingulated cortex and lateral surrounding cerebral regions, and fALFF value decreased in the cerebral regions of the peripheral cortex of the calcarine fissure; in moxibustion of 3 cm distance, fALFF value increased in the brain regions of the right and medial side and paracingulated gyrus, and fALFF value decreased in the cerebral zone of the left middle temporal gyrus; in moxibustion of 4 cm distance, fALFF value increased in the brain regions of the right and medial and paracingulated gyrus; and in moxibustion of 5 cm distance, fALFF value increased in the brain regions of the left hippocampus. In comparison of the value of regional homogeneity (ReHo), it has been found that in moxibustion of 2 cm distance, ReHo value increased in the cerebral zone of the posterior lobe of the right cerebellum, and ReHo value decreased in the cerebral zone of the right occipital lobe; in moxibustion of 3 cm distance, ReHo value increased in the brain regions of the left cerebellar posterior lobe and left frontal lobe, and ReHo value decreased in the cerebral zone of the right inferior temporal gyrus; in moxibustion of 4 cm distance, ReHo value increased in the brain regions of the right superior frontal gyrus and ReHo value decreased in the brain regions of the right parietal lobe and angular gyrus; in moxibustion of 5 cm distance, ReHo value increased in the cerebral zone of the right frontal lobe and ReHo value decreased in the cerebral zone of the right brainstem. Conclusion: In moxibustion of 3 cm distance, the changes in the brain regions basically conform to the transmission route of body trunk temperature.

Objectvie: To observe the law of heat transfer in Zusanli during the process of moxibustion. Methods: Thetemperature change of Zusanli was detected by self-made high-precision temperature sensor while moxibustion on lowerextremities acupoints on six meridians of foot in healthy volunteers for fifteen minutes, the temperature change curve andtemperature change rate curve were drawn with Origin software. Results: Temperature change curve of Zusanli was thebiggest when moxibustion on acupoints in stomach meridian of foot yangming, especially for Shangjuxu acupoint.Whenthe acupoints near the level of Zusanli are moxibusted, the temperature change curve of Zusanli changes obviously.Temperature change rate curves of Zusanli were basically in coincidence when moxibustion on lower extremities acupoints on six meridians of foot, and it had a downward trend. Conclusion: Heat transfer between meridians andacupoints have propagated sensation along channel, regional characteristics, consistency of transmission rate, in theprosess of moxibustion.

Objective:
To explore the association of vitamin D deficiency with anxiety and depressive symptoms as well as their comorbidity, so as to provide references for improving the mental health of children and adolescents.
Methods:
From October to December 2021, a total of 1 323 students from four middle schools in Shenzhen were selected by using convenience sampling method for a questionnaire survey and physical examination. Fasting blood samples were collected to detect vitamin D levels. The Chi square test and multiple Logistic regression model were used to analyze the association of vitamin D deficiency with anxiety and depressive symptoms and their comorbidity among middle school students.
Results:
The detection rates of anxiety, depressive, and thier comorbidities in middle school students were 33.0%, 21.5% and 16.3%, respectively. After adjusting for confounding factors, vitamin D deficiency was positively associated with the risk of anxiety symptoms ( OR=1.59, 95%CI =1.02-2.46), depressive symptoms ( OR=1.94, 95%CI =1.22-3.09) and anxiety depressive comorbid symptoms ( OR=1.75, 95%CI =1.06-2.90) in secondary school students ( P <0.05).
Conclusion
Vitamin D deficiency is associated with an increased risk of anxiety, depressive and their co morbidity symptoms in middle school students, and the directionality of the association should be further studied.

Objective:
The aim of this study was to establish a comprehensive concise health index (CHI) for evaluating adolescents, so as to provide a basis for determining the overall health status of adolescents in China.
Methods:
On the basis of a literature review and consensus among core researchers, adolescent CHI indicators in the following five dimensions were assessed:physical growth, physical fitness, common diseases, mental health and behavioral health. A total of 24 experts used an analysis hierarcgy process (AHP) to calculate the indicators subjective weights. In addition, from October to December of 2021, two regions, A and B were selected to conduct empirical research, and the CRITIC method was used to calculate the objective weights of the indicators. Finally, the weight coefficients were determined through the AHP-CRITIC combination weight method, and comprehensive evaluation was performed with the TOPSIS method.
Results:
Across academic period and genders, the combined weighted coefficients of the health indicators were as follows:BMI, 0.081-0.095; waist circumference, 0.070-0.081; relative grip strength, 0.101-0.108; myopia, 0.110-0.128; dental caries, 0.055-0.070; psychological symptoms, 0.240-0.262; physical exercise, 0.085-0.115; screen time, 0.097-0.111; and sleep duration, 0.086-0.103. The health index of middle school students in city A (0.626±0.065) was significantly higher than that in city B(0.613±0.066)( t=6.34, P <0.01).
Conclusion
