Objective: To investigate prevalence and influencing factors of overweight and obesity among children and adolescents in Jiangxi Province, and to provide the basis for strategies for prevention and treatment of overweight and obesity. Methods: Using stratified random cluster sampling ,a total of 77 780 primary and middle school students in 11 districts of Jiangxi Province were investigated with physical examination and questionnaire during March to November in 2019. Results: The detection rates of overweight and obesity of children and adolescents in Jiangxi province were 20.5% and 8.4%, respectively. Which decreased with the increase of the learning stage（ χ 2=178.65, 389.86）,with significantly higher in boys and urban areas （ χ 2=1 061.06, 504.21;56.17, 34.14）（ P ＜0.01）.In different economic areas, the detection rates of overweight and obesity in moderate economic area( 23.3 %, 9.7%) were the highest, followed by high economic area (21.1%, 8.7%) and low economic area(18.2%, 7.2%), and the differences were statistically significant（ χ 2=266.29, 143.90， P ＜0.01）.The results of multivariate Logistic regression analysis showed that in terms of social demography, overweight and obesity of children and adolescents in Jiangxi Province were associated with economic area, residence, learning stage and gender; in terms of dietary behavior, overweight of children and adolescents in Jiangxi Province was associated with consumption frequency of sugary drinks, sweets, fresh fruits and vegetables, and the influencing factors of obesity were consumption frequency of sweets and fresh fruits( P <0.05). Conclusion The situation of overweight and obesity of children and adolescents in Jiangxi Province is sorrisome, and comprehensive prevention and control should be carried out with the joint efforts of society, school and family.

Objective: To investigate blood lipid status among children and adolescents in Jiangxi Province, and to provide the basis for prevention and control of dyslipidemia. Methods: Using the method of stratified cluster random sampling,a total of 14 535 children and adolescents aged 6-17 years old were selected from Jiangxi Province in 2019. With physical measurement and blood tests for fasting blood total cholesterol(TC), triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C) levels, dyslipidemia was determined by the definition of dyslipidemia prevention consensus of specialists in Children and Adolescents. Results: The dyslipidemia rate was 14.9%, and the abnormal rates of TC,TG, LDL-C and HDL-C were 5.9%,7.4%,2.9% and 3.4%, respectively.The prevalence of dyslipidemia was higher in female(15.7%) than in male(14.1%)(χ 2=8.01, P<0.01). The prevalence of dyslipidemia in primary school, middle school and high school students was 13.8%,15.5% and 17.3%, respectively(χ 2=21.14，P<0.01),and in students of normal weight, overweight and obesity was 12.8%, 21.9%, 30.0%, respectively(χ 2=297.20, P<0.01). Conclusion The prevalence of dyslipidemia among children and adolescents in Jiangxi Province is lower than the national level, but the current situation cannot be ignored.

Objective To investigate the expressions of inflammation- and fibrosis-related genes in perinephric and subcutaneous adipose tissues in patients with adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome. Methods The perinephric and subcutaneous adipose tissues adipose tissues were obtained from 8 patients with ACTH-independent Cushing's syndrome undergoing laparoscopic retroperitoneal adrenalectomy. Real-time PCR was used to detect the mRNA expression levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), matrix metallopeptidase 2 (MMP-2), TIMP metallopeptidase inhibitor 1 (TIMP-1), early growth response 1 (EGR1), CCAAT/enhancer binding protein β(CEBPβ), uncoupling protein 1(UCP-1), PPARγ coactivator 1 alpha (PGC1α) and cell death-inducing DFFA-like effector a (CIDEA). Results The mRNA level of CIDEA was significantly higher in the perinephric adipose tissue (peri-N) than in the subcutaneous adipose tissue (subQ) (P<0.05). The expressions of CEBPβ, UCP-1, and PGC1αmRNA in the peri-N were similar with those in the subQ. The expressions of IL-6, TIMP1 and EGR1 mRNA in the subQ were significantly higher than those in the peri-N (P<0.05). No significant difference in TNF-α and MMP-2 mRNA levels was found between peri-N and subQ. Conclusion The expression levels of the inflammation-and fibrosis-related genes are higher in the subQ than in the peri-N of patients with ACTH-independent Cushing's syndrome, suggesting that chronic exposure to endogenous hypercortisolism may cause adipose tissue dysfunction.

Objective:To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 （lymph-vascular space invasion-positive, LVSI +）- Ⅰb1 cervical cancer patients with different tumor sizes. Methods:Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results:(1) A total of 4 891 patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.367, 95% CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups （94.1% vs 95.4%, P=0.151）. While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS ( HR=1.420, 95% CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS ( P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups ( P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.705, 95% CI: 1.088-2.674, P=0.020). Conclusions:For patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.
