OBJECTIVES:
The prevalence of overweight and obesity among children and adolescents continues to rise, becoming one of the most serious global public health issues of the 21st century. Given the differing growth and development environments between urban and rural children, associated risk factors also vary. This study aims to explore the distribution characteristics and influencing factors of overweight and obesity among urban and rural primary and secondary school students in Hunan Province, providing scientific evidence for targeted interventions.
METHODS:
A stratified, randomized cluster sampling method was used to select participants. A total of 197 084 students from primary and secondary schools across 14 prefectures in Hunan Province underwent physical examinations and questionnaire surveys. Population and spatial distribution characteristics of overweight and obesity were analyzed. Spatial distribution maps and spatial autocorrelation analyses were conducted using ArcGIS. Multivariate Logistic regression was used to identify influencing factors for overweight and obesity.
RESULTS:
The overall overweight and obesity rates among students in Hunan Province were 14.7% and 10.9%, respectively. Both rates were higher in urban areas than in rural counties (16.0% vs 13.9% for overweight; 12.1% vs 10.2% for obesity). Among both urban and rural students, boys had higher rates of overweight and obesity than girls. Higher-grade students had a higher overweight rate but a lower obesity rate than lower-grade students. In urban areas, the overweight and obesity rates of Han Chinese primary and secondary school students are lower than those of ethnic minority students (both P<0.05). In rural areas, the obesity rate of Han primary and secondary school students is lower than that of ethnic students (P<0.05). Across cities and prefectures, urban overweight and obesity rates ranged from 14.7% to 18.7% and 8.4% to 20.6% respectively, while rural rates ranged from 10.9% to 17.2% and 6.6% to 13.7% respectively. Spatial autocorrelation analysis revealed high-value clusters of overweight/obesity in urban areas of Changde and Zhangjiajie, and in rural areas of Loudi, Huaihua, and Shaoyang. Multivariate Logistic regression showed that gender, school stage, ethnicity, frequency of fresh vegetable intake, and sleep duration were associated with overweight and/or obesity in both urban and rural students. In urban students, frequency of fried food and fresh fruit intake, breakfast habits, physical activity on weekdays and holidays, and screen time on computers were also significant. In rural students, TV viewing time and sedentary duration were additional relevant factors.
CONCLUSIONS
The situation of overweight and obesity among primary and secondary school students in Hunan Province remains concerning. Greater attention should be paid to regions with high-value clusters of overweight/obesity, and targeted interventions should be developed based on urban-rural differences in influencing factors.

OBJECTIVE:
To explore the effect of auricular point pressure on anesthetic recovery in the patients undergoing laparoscopic cholecystectomy.
METHODS:
One hundred and forty patients undergoing laparoscopic cholecystectomy were randomized into a trial group (52 cases, 2 cases dropped out) and a control group (52 cases, 2 cases were eliminated). In the control group, the conventional anesthesia program and recovery intervention were adopted. In the trial group, on the basis of the regimen as the control group, the intervention of auricular point pressure was supplemented. The auricular points on the right side were selected, including sympathetic (AH6a), brain (subcortex, AT4), thalamus, exciting point, heart and sore center. One day before operation, the auricular point pressure started; and the auricular points were stimulated specially before anesthesia (T0), at the moment of operation ending (T1), when entering the recovery room, at the moment of the tube removal (T2) and in 10 min of the tube removal (T3), respectively; each auricular point was pressed for 1 min a time. The recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, and the time of exiting recovery room were compared between the two groups. The score of pain visual analogue scale (VAS) and that of Richmond agitation-sedation scale (RASS) at T2, T3 and when exiting recovery room (T4), and the relevant circulatory indexes (heart rate [HR], systolic blood pressure [SBP], diastolic blood pressure [DBP] and mean arterial pressure [MAP]) at T0, T1, T2 and T3 were observed in the two groups.
RESULTS:
In the trial group, the recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, the time of exiting recovery room were shorter than those of the control group (P<0.01, P<0.05). The pain VAS and RASS scores at T2, T3 and T4, as well as HR, SBP, DBP and MAP at T0, T1, T2 and T3 were not different statistically between the two groups (P>0.05).
CONCLUSION
Auricular point pressure can shorten the recovery time from anesthesia in the patients undergoing laparoscopic cholecystectomy.

Objective:
This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder.
Methods:
Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration.
Results:
The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week.
Conclusion
PMTS is safe and effective in improving insomnia disorders.

OBJECTIVE:
To observe the clinical efficacy of dynamic qi acupuncture for acute lumbar sprain, and to explore the differences of different needle retention time on the improvement of pain, lumbar mobility and lumbar dysfunction.
METHODS:
A total of 160 patients with acute lumbar sprain were randomly divided into an observation group A (40 cases, 4 cases dropped off), an observation group B (40 cases, 2 cases dropped off), an observation group C (40 cases, 4 cases dropped off) and a medication group (40 cases, 6 cases dropped off). The patients in the observation group A, the observation group B and the observation group C were treated with acupuncture at "lumbago point" and Sanjian (LI 3) on the left side, and during the needles were kept for 10, 20 and 30 min respectively, the patients were required to take tolerable lumbar active activities, once a day; the patients in the medication group were treated with celecoxib capsules, 0.2 g each time, twice a day. All the patients were treated for 5 d. Before and after treatment, the scores of numerical rating scale-11 (NRS-11), lumbar range of motion (ROM) and modified Oswestry disability index (ODI) were observed, and the clinical efficacy of each group was evaluated.
RESULTS:
After treatment, the scores of NRS-11, ROM and ODI in each group were decreased compared before treatment (P<0.01). The decreased degree of NRS-11, ROM and ODI in each observation group was greater than that in the medication group (P<0.05), and the decreased degree of ROM and ODI in the observation group B and the observation group C was greater than that in the observation group A (P<0.05). The total effective rates were 94.4% (34/36) in the observation group A, 94.7% (36/38) in the observation group B and 97.2% (35/36) in the observation group C, respectively, which were higher than 79.4% (27/34) in the medication group (P<0.05).
CONCLUSION
Dynamic qi acupuncture with needle retention for 10, 20 and 30 min all could effectively improve the pain, lumbar mobility and lumbar dysfunction in patients with acute lumbar sprain. If the lumbar dysfunction is severe, needle retention for 20 min or more is recommended.

Objective:To analyze the horizontal scientific research projects from 2015 to 2019 by the provincial Centers for Disease Control and Prevention (CDC) in China, and to compare the regional differences, in order to provide the suggestion on the scientific management of CDC.Methods:The horizontal scientific research projects from 2015 to 2019 were retrospectively analyzed by questionnaire survey. Multiple linear regression models were adopted to examine the trend, and variance analyses were used to test the differences in horizontal scientific research projects among the Eastern, Central, and Western regions.Results:From 2015 to 2019, provincial CDC have received RMB 124.3 million of horizontal scientific research project funds totally, of which 51.9% were funded by enterprises, and 86.9% were undertaken by provincial CDC themselves. There were no statistical significance in the change of research project funds obtained by provincial CDC ( F=0.46, P = 0.764) during this period.The number of horizontal scientific research projects undertook or participated by provincial CDC in the Eastern region were more than that of the Central and Western region ( F = 5.85, P = 0.004; F = 5.03, P = 0.008). Conclusions:The horizontal scientific research projects obtained by the provincial CDC remained stable in recent years while distribution was unbalanced in the region areas. It is suggested to innovate the management mode of scientific research projects with strengthening the trans-agency, trans-department and trans-regional cooperation.

OBJECTIVE:
To investigate the relationship between sleep parameters and suicidal ideation in patients with late-life depression (LLD).
METHODS:
Seventy-seven LLD patients over 60 years old from Sir Run Run Shaw Hospital of Zhejiang University during July 2017 and July 2018 were included in the study. All patients were assessed with Hamilton Depression Rating Scale (HAMD) and polysomnography (PSG) overnight. The suicidal score of item 3 in HAMD (HAM-D3)was used to define whether there was a suicidal ideation. Participants were subsequently grouped according to endorsement of presence (HAM-D3 score ≥1, =46) versus absence (HAM-D3 score=0, =31) of suicidal ideation symptoms. The sleep efficiency, total sleep time, wakefulness after sleep onset, rapid eye movement percent/latency, and non-rapid eye movement sleep stages 1-3 (N1-N3) were assessed. ANOVA analyses were conducted to explore the correlation of sleep parameters with suicidal ideation between the groups with and without suicidal ideation. In model 1, the HAM-D3 constituted the independent variable in separate ANOVA tests; in model 2 the impact of depressive symptoms were assessed as a covariate with sleep parameters.
RESULTS:
There was less stage N3 [(55±41)min, =-4.731, <0.05] and the reduced percentage of N3 [(15±11)%, =-4.194, <0.05] in LLD patients with suicidal ideation, compared with the LLD patients without suicidal ideation [(104±49) min, (26±11)%]. Correlation analyses revealed that there was a significant correlation between the suicidal ideation and the percentage of stage N3 and sleep time of stage N3 (both <0.05).
CONCLUSIONS
Suicidal ideation is associated with less N3 sleep in LLD patients.

Objective To investigate the effects of enteral nutritional emulsions on glucose and lipid metabolism in elderly patients with diabetes. Methods This randomized controlled trail recruited 80 elderly diabetic patients whose MNA-SF scores were between 0-11 with dysphagia or inability for oral feeding and who were randomized into a TPF-DM group ,a TPF-D group ,a TPF-T group ,and a TPF group.Glycolipid metabolism indexes and nutritional indexes were measured before intervention and at 1 m ,2 m and 3 m after intervention. Results Compared with baseline levels , FBG and HbA1c declined in the TPF-DM group[(5.70 ± 0.69)mmol/L vs .(7.90 ± 1.71)mmol/L and (6.39 ± 1.11)% vs .(7.92 ± 1.50)%,all P<0.05]and the TPF-D group[(5.72 ± 1.12)mmol/L vs . (7.63 ± 1.73 )mmol/L and (6.86 ± 0.97 )% vs .(7.81 ± 1.04 )%,all P< 0.05 ]after 3 months of treatment ,but no significant difference was found between these two groups. The TPF-DM ,TPF-D , TPF-T groups showed significantly narrower fluctuation ranges of 24 h blood glucose levels after 3 months[(2.20 ± 0.88)mmol/L vs .(4.43 ± 2.07)mmol/L ,(2.94 ± 1.16)mmol/L vs .(4.22 ± 1.60) mmol/L ,(3.21 ± 1.64)mmol/L vs .(4.36 ± 1.88)mmol/L ,all P < 0.05).Serum albumin levels increased in all four groups ,compared with baseline levels (all P<0.05) ,but there was no significant difference between the groups(all P>0.05). Furthermore ,the serum HDLC level increased in all four groups than baseline (all P< 0.05). Conclusions Enteral nutritional emulsions containing slow release starch and fructose ,dietary fibers and proper ω6 and ω3 ratio can stabilize blood sugar ,regulate blood lipids ,and improve nutritional status.
