Objective: To analyze correlation between overweight and obesity among primary school students in Lanzhou with exercise and environmental factors around schools, and to provide a reference for reducing the overweigh and obesity rate of students. Methods: Using cluster random sampling method, a total of 3 600 pupils from grade 4 to grade 6 in 8 primary schools in 4 districts of Lanzhou were investigated. Logistic regression model was used to analyze the relationship between overweight and obesity, exercise and environmental factors surrounding schools. Results: The overweight rate was 13.8% (18.0% for boys and 9.5% for girls) and the obesity rate was 10.8%(11.7% for boys and 9.8% for girls), there was statistical significance in the differences of overweight rate between genders(χ2=55.10, P<0.01). There was no statistical significance in the differences of obesity rate between genders(χ2=3.39, P=0.07). The primary environmental factors causing overweight and obesity among boys included number of Internet cafes(OR=1.81), while for girls it was number of fast food restaurants(OR=2.39). Conclusion Too many Internet cafes and fast food restaurants surrounding school associates with higher risk of obesity among students. Public health interventions should be implemented targeting surrounding environment of schools, which might help reducing the occurrence of overweight and obesity in primary school students.

Objective To explore the effects of skill-training on social function in patients with schizophrenia recession. Methods 60 patientswith schizophrenia recession were divided into 2 equal groups (n=30) for 1-year treatment. The control group was treated only withdrugs, and the treatment group was treated with skill-training in addition. The patients were assessed with the Scale of Social Skill of ChronicSchizophrenic Inpatients (SSSI) and the Positive and Negative Symptom Scale (PANSS) before, 6 months and 12 months after treatment.Results The total scores of PANSS decreased significantly in the treatment group compared with the control group (P<0.01). The scores ofSSSI decreased significantly in the treatment group after treatment. However, there was no significant differences in the control group (P>0.05) 6 months after treatment, but was 12 months after treatment (P<0.05). Conclusion Based on the medicine treatment, skill-training mayimprove the flinched mental symptom to remain the social function.

Objective: To explore health self-management, adaptation, and perceived stress among nursing interns in medical colleges and universities under the normal prevention and control of COVID-19, and to provide a scientific basis for the health management of practice nursing students. Methods: Medical colleges in the Inner Mongolia region were selected to study 263 nursing student interns by cluster random sampling. The survey was conducted using the Health Self-Management Ability Assessment Scale, the Chinese College Students Adjustment Scale and the Perceived Stress Scale. Results: The total score of health self-management ability of nursing students during internship was (138.31±20.13). The total score of health self-management ability of nursing students with different educational backgrounds and different residence places was statistically significant ( F/t =3.51, 2.46, P < 0.05 ); the total adaptive score was (3.17±0.72); during the epidemic, the total score of perceived stress was (11.52±2.79), and the difference in the total score of perceived stress among nursing students with different educational backgrounds was statistically significant ( t=4.05, P <0.05). Pearson analysis showed that there was a significant negative correlation between health self-management ability, adaptation, and perceived stress among nursing students during the epidemic period ( r =-0.31, -0.35, P <0.01). Conclusion There was a close relationship between perceived stress of nursing students and health self-management and adaptation; the educators in medical colleges should actively explore strategies to improve the health self-management ability and adaptation level of nursing students to enhance the psychological adjustment ability of nursing students to maintain good physical and mental health.

The Alataw Pass, near the Ebinur Lake Wetland (northwest of China) and Taldykorgan (east of Kazakhstan), is a natural habitat for wild rodents. To date, little has been done on the surveillance of Bartonella spp. and Wolbachia spp. from fleas in the region. Here we molecularly detected Bartonella spp. and Wolbachia spp. in wild rodent fleas during January and October of 2016 along the Alataw Pass-Kazakhstan border. A total of 1,706 fleas belonging to 10 species were collected from 6 rodent species. Among the 10 flea species, 4 were found to be positive for Wolbachia, and 5 flea species were positive for Bartonella. Molecular analysis indicated that i) B. rochalimae was firstly identified in Xenopsylla gerbilli minax and X. conforms conforms, ii) B. grahamii was firstly identified in X. gerbilli minax, and iii) B. elizabethae was firstly detected in Coptopsylla lamellifer ardua, Paradoxopsyllus repandus, and Nosopsyllus laeviceps laeviceps. Additionally, 3 Wolbachia endosymbionts were firstly found in X. gerbilli minax, X. conforms conforms, P. repandus, and N. laeviceps laeviceps. BLASTn analysis indicated 3 Bartonella species showed genotypic variation. Phylogenetic analysis revealed 3 Wolbachia endosymbionts were clustered into the non-Siphonaptera Wolbachia group. These findings extend our knowledge of the geographical distribution and carriers of B. rochalimae, B. grahamii, B. elizabethae, and Wolbachia spp. In the future, there is a need for China-Kazakhstan cooperation to strengthen the surveillance of flea-borne pathogens in wildlife.

Objective: To investigate the change in intestinal flora in Mongolian students with anxiety,so as to provide basis for exploring the relationship between flora and secretion expression in vivo. Methods: The Self rating Anxiety Scale(SAS)was used to assess anxiety in medical college students; then a semi structured interview was administered. Fecal samples that met the inclusion criteria were collected and divided into anxiety (SAS score≥50) and control groups (no anxiety, SAS score<50) according to the standard score of SAS. Samples provided by Mongolian female students were selected from each group. The total bacterial DNA was extracted from the fecal samples for PCR amplification and NovaSeq 2x250bp high throughput sequencing was performed for the V3- V4 region of 16S rDNA gene to obtain the biological information of the intestinal flora. The intergroup OTU, structural diversity, significant difference, and LEfSe analyses were performed with information mining of the literature think tanks. Results: Anxiety existed in 23.86% of the Mongolian students,and 16.96% of the Han people. A Chi square test showed no significant difference in detection of anxiety between Mongolian and Han college students ( P =0.07). Analysis of the alpha diversity index showed that the Shannon index, Simpson index, Chao1 index, and Observed species did not differed significantly between the two groups( t =8.0， 9.0 ，6.0，6.5). The difference in abundance of some bacteria was significant at the Class, Order, Family, and Genus levels between the two groups( t =-2.26-2.57，-5.08-3.58，-2.65-2.09， P <0.05). Conclusion The alpha diversity index showed that there was no significant difference in the abundance and diversity of intestinal flora between the two groups. While there were significant differences at different classification levels, the results suggest that the structure of intestinal flora can change in students with anxiety.

Objective: To explore the effect of proprioception combined with core stability training on the static balance ability and dynamic balance ability of college students, and to provide an experimental basis for studying body balance ability and preventing sports injuries. Methods: In August 2019, 112 non sports students from Shandong Institute of Physical Education were recruited, and 52 subjects were selected as the intervention group and 60 as the control group by random number table method. The intervention group was given proprioceptive training combined with core stability training, while the control group was given core stability training. The static and dynamic balance abilities of the two groups of subjects before and after training were compared. Results: The static balance ability of the intervention group was higher than that before the intervention ( F =2.17， P <0.05) at the 5th and 11th weeks, which were 18.31% and 47.37% higher, respectively. The ability to stand on one foot with eyes closed at the 11th week in the intervention group was higher than that in the control group at the 11th week( t =2.25， P <0.05). After training, the equilibrioception of the intervention group was improved, increasingly improved in the 11th week. And compared with that in intervention group in the 5th and 11th week, the ability was also higher than the balance ability of the intervention group before the intervention( F =2.37， P <0.01), 12.01% and 12.99% higher, respectively. Conclusion Proprioception and core stability training can effectively improve the static and dynamic balance ability of college students, and the training effect of proprioceptive training combined with core stability training is better than that of core stability training.

Objective: To understand prevalence and influencing factors of abnormal spinal curvature in primary and secondary school students aged 10-14 years in Inner Mongolia, and to provide reference for relevant measures. Methods: A total of 92 094 primary and secondary school students aged 10-14 years were selected by multi stage cluster sampling, and were investigated with questionnaire. Results: A total of 1 957 participants (2.13%) with abnormal spinal curvature were detected, including 1 768( 90.34 %) with scoliosis. Significant differences in the detection rate of abnormal spinal curvature were observed among students with different myopia status and posture of sitting and standing ( χ 2=23.82, 9.84, P <0.05). Logistic regression analysis showed that different ethnic groups, monitoring points, age and area were main factors for risk of spinal curvature abnormalities in primary and secondary school students aged 10-14 years; good nutritional status, left right rotation of class seats, seat height adjustment according to height were associated with lower rate of spinal curvature abnormalities ( P <0.05). Conclusion Various measures should be taken simultaneously to reduce the prevalence of abnormal spinal curvature in primary and middle school students aged 10-14 years.

Objective: To understand the current situation and influencing factors of scoliosis in 12-year-old students from Inner Mongolia Autonomous Region, so as to provide scientific basis for accurate prevention and control of abnormal spinal curvature. Methods: From October to November 2021, a total of 18 399 students aged 12 were selected by region and school level by stratified random cluster sampling method, and spinal curvature screening and questionnaire survey of common diseases and health influencing factors among students were carried out. Chi squared test was used for single factor analysis, and binary Logistic regression model was used for multi factor analysis. Results: A total of 397 students (2.2%) were detected with abnormal curvature of the spine, including 368 students (2.0%) with scoliosis. Among them, 205 cases were in the lumbar thoracic segment with a detection rate of 1.1%, 173 cases were in the thoracic segment with a detection rate of 0.9%, and 141 cases were in lumbar thoracic segment with a detection rate of 0.8%. Binary Logistic regression analysis showed that urban area, economic area(moderate), attending tutorial classes before primary school and class seats never changed regularly were positively correlated with the occurrence of scoliosis among 12 year old students ( OR =1.95,1.67,1.76,1.71, P <0.05). Obesity, attending an average of 3 or 4 physical education classes per week, attending physical fitness and beauty classes before primary school were negatively correlated with the occurrence of scoliosis among 12 year old students ( OR =0.69,0.31,0.36,0.71, P <0.05). Conclusion The prevalence of scoliosis among 12-year-old students in Inner Mongolia Autonomous Region is not optimistic. It should pay attention to the prevention and control of scoliosis in students before the age of 12, actively prevent the occurrence and progress of scoliosis.
