The effect of AMP-activated protein kinase (AMPK) on KiSS-1 mRNA levels was detected by realtime PCR in the hypothalamic GT1-7 neurons. The promoter activity of KiSS-1 gene was detected by DualLuciferase Reporter Assay System.The effects of AMPK on the protein expression and subcellular distribution of SP1 were determined by Western blot.The results showed that AMPK reduced the mRNA expression and promoter activity of KiSS-1 gene while SP1 increased the promoter activity of KiSS-1 gene. Besides,AMPK alse decreased the translocation of SP1.These results suggest that AMPK may inhibit the expression of KiSS-1 gene by decreasing the translocation of SP1 from cytoplasm to nucleus in the hypothalamus GT1-7 neurons.

BACKGROUND: Many studies have shown that cell-assisted lipotransfer promotes the survival of fat implants, but there are few studies exploring stromal vascular fraction (SVF) -assisted fat transplantation for improving facial skin quality. OBJECTIVE: To evaluate the clinical effect of autologous adipose-derived SVF-assisted autologous fat transplantation in the improvement of facial skin quality. METHODS: From September 2016 to June 2018, in the Plastic and Cosmetic Center, the Affiliated Hospital of Xuzhou Medical University, 20 patients were recruited and then randomly divided into experimental group and control group, namely SVF-assisted fat transplantation and simple fat transplantation, respectively. A VISIA skin detector was used to detect facial skin quality of patients preoperatively and 6 months postoperatively, including spots, wrinkles, texture, pores, ultraviolet spots, brown spots, couperose skin and porphyrin. RESULTS AND CONCLUSION: The effect of improvement in wrinkles and texture in the experimental group was better than that of the control group, and the difference was statistically significant (P < 0.05). In terms of spots, pores and couperose skin, the therapeutic effect in the experimental group was better than that in the control group, but the difference was not statistically significant (P> 0.05). There was no significant difference between the two groups in the improvement of ultraviolet spot and brown spots. The porphyrin was not affected by the subjects. To conclude, SVF can promote the effect of fat transplantation in the improvement of facial skin quality.

Objective:To explore the application effect of continuous nursing based on hybrid electronic platform and fragmentation time in the out-of-hospital rehabilitation of patients with anterior cruciate ligament reconstruction.Methods:This was a randomized controlled study. From April 2020 to October 2021, a total of 90 patients undergoing anterior cruciate ligament reconstruction in Weifang People′s Hospital were selected as the research objects by convenience sampling. Forty patients from April to December 2020 were selected as control group, and 45 patients from January to October 2021 were selected as intervention group. The control group implemented routine discharge guidance and follow-up, while the intervention group was given continuous nursing plan based on the concept of hybrid electronic platform and fragmented time. Before operation and 1, 3 and 6 months after operation, the knee range of motion and Lysholm score of patients in the two groups were analyzed. At 1, 3 and 6 months after operation, the rehabilitation exercise compliance score, self-efficacy score and knee stability examination of the two groups were analyzed.Results:A total of 41 patients in each group completed the study. At 1 month after operation, the knee range of motion, Lysholm score, rehabilitation exercise compliance score and self-efficacy score of intervention group were (96.46 ±3.58) ° and (53.54 ± 6.57), (69.17 ± 6.27), (4.01 ± 0.38) points, respectively. In the control group, they were (89.02 ± 4.22)° and (45.02 ± 7.61), (56.78 ± 8.45), (3.61 ± 0.42) points. At 3 months after operation, they were (136.83 ± 4.30)° and (72.76 ± 4.96), (60.71 ± 5.87), (4.97 ± 0.32) points in the intervention group, (133.54 ± 3.58)° and (69.83 ± 6.65), (56.73 ± 8.57), (4.83 ± 0.45) points in the control group, respectively. At 6 months after operation, they were (139.39 ± 1.99)° and (85.61 ± 6.11), (57.71 ± 7.41), (6.58 ± 0.96) points in the intervention group, (138.29 ± 2.65)° and (81.80 ± 6.38), (47.90 ± 6.02), (6.35 ± 1.23) points in the control group, respectively. The knee range of motion, Lysholm score and rehabilitation exercise compliance score of the intervention group were better than those of the control group at 1, 3 and 6 months after operation, and the differences were statistically significant ( t values were 2.12-8.61, all P<0.05). The self-efficacy score of the intervention group was higher than that of the control group at 1 month after operation, and the difference was statistically significant ( t=4.57, P<0.05). Conclusions:The continuous nursing program based on hybrid electronic platform and fragmented time can improve the knee function of patients with anterior cruciate ligament reconstruction in the early postoperative period, improve the compliance of rehabilitation exercise and the level of early self-efficacy.

Objective: To understand parents attitudes towards adolescent sexual education in Baoshan City of Yunnan Province, and to explore the correlation between attitudes and their proactive behavior in adolescent sexual education, so as to provide reference for improving parents initiative in adolescent sexual health education. Methods: From November to December 2022, a stratified random cluster sampling method was used to select 7 389 parents of students from 35 primary, middle, and high schools in Baoshan City of Yunnan Province for a questionnaire survey on adolescent sexual health education in parents schools. Chi-square tests were conducted to compare the attitudes of parents towards sexual health education among different groups and their proactive behavior in providing sexual health education to their children. A multivariate Logistic regression model was used to analyze the correlation between parents attitudes towards sexual education and proactive sexual health education. Results: Totally 43.17% ( 3 190 ) of parents had a more open attitude towards sex education for their children, with parents of girls, parents of elementary school students, mothers, <30 years old, junior high school education, workers, service personnel, married, harmonious relationships with their children and democratic parents had a higher rate of actively providing sex education for their children ( χ 2=4.65, 401.92, 23.53 , 197.50, 38.18, 13.65, 6.54, 8.07, 32.17, 96.58, P <0.05). Parents with a more conservative attitude towards sex education and parents of boys were negatively correlated with parents actively providing adolescent sexual health education to their children ( OR =0.86, 0.38, P <0.05). Parents who were <30, 30-<40, 40-50 years old, individuals/businesses, married, divorced, had a good and decent relationship with their children were positively correlated with their parents proactive adolescent sexual health education for their children ( OR =1.50, 1.90, 1.37, 1.22, 1.60, 1.32, 1.94, 1.53, P <0.05). Conclusion A more open attitude towards adolescent sexual health education can serve as a predictive factor for proactive adolescent sexual health education. In order to increase the rate of family sexual health education, it is recommended to enhance parents awareness of their responsibility for their children s sexual health education, promote harmonious parent-child relationships between parents and children, and communicate with their children with an open attitude.

Objective To explore the mechanisms associated with symptom burden and depres-sion in hepatocellular carcinoma patients after hepatectomy.Methods A total of 230 hospitalized pa-tients with hepatocellular carcinoma who were underwent hepatectomy for the first time were selected as study subjects.A self-administered General Information Questionnaire,MD Anderson Symptom In-ventory,Patient Health Questionnaire,Connor-Davidson Resilience Scale,and Pittsburgh Sleep Quality Index were used to investigate sociodemographic,sociodemographic data,symptom burden,depression,psychological resilience,and sleep quality of postoperative hepatocellular carcinoma pa-tients.Pearson correlation analysis was used to identify specific associations among variables.The mediating and moderating effects of psychological resilience and sleep quality between symptom bur-den and depression were analyzed using the Process.Results Psychological resilience partially me-diated the association between symptom burden and depression(β=-0.137,SE=0.084,95％CI,-0.243 to-0.082),with the mediating effect accounting for 44.08％of the total effect,and the interaction term between symptom burden and sleep quality had predictive value for psychological re-silience(β=-0.014,t=-6.209,P＜0.001).Conclusion Postoperative symptom burden in hepatocellular carcinoma patients can play a role in depression through psychological resilience,where the effect of symptom burden on psychological resilience is moderated by sleep quality.Clinical staff should take reducing patients'postoperative symptom burden and improving psychological elastic-ity with sleep quality as important goals and develop appropriate nursing interventions to reduce the risk of depression in patients.

Objectives:Compare the differences between the intervention and control groups in changes of primary outcomes(body mass index[BMI]and waist-to-height ratio[WHtR])and secondary outcomes(nutrition knowledge of children and parents),from baseline to the 6-and 12-month follow-ups;examine the associations of changes in nutrition knowledge of children and their parents with children's changes in BMI and WHtR.Data sources:Data collected from four schools in two poverty-stricken counties in northern Shaanxi Province in 2020-2021.Methods:A multifaced intervention program targeted children(promoting healthy diet and nutrition education)and their parents(promoting nutrition knowledge)was conducted in the interventional group.Four schools,with two in each group,were randomly allocated to the intervention or control group,with 814 eligible children aged 7.1 to 12.8 years.The control group conducted myopia promotion.Differences in changes of BMI and WHtR between groups were compared with t-test.Mixed-effects model was used to examine the associations between changes in nutrition knowledge of children and parents with changes in children's BMI and WHtR.Results:At the 6-month follow-up,the difference in changes in BMI between the intervention and control groups was 0.4 kg/m 2(P＜0.001).At the 12-month follow-up,the difference in changes in BMI and WHtR between intervention and control groups was 0.1 kg/m2(P＜0.001)and 0.01 kg/m2(P＜0.001).In the intervention group,the nutrition knowledge awareness rate of children increased from 16.9％(69/409)at baseline to 21.3％(87/409)at 6-month,and 22.7％(93/409)at 12-month.The awareness rate of nutrition knowledge of parents also fluctuated,from 5.6％(23/409)to 6.6％(27/409)and 5.4％(22/409).However,the difference in changes in nu-trition knowledge between intervention and control groups was non-significant.The 6-month follow-up changes in children's nutrition knowledge scores were negatively associated with changes in BMI in girls(β=-0.26,95％confidence interval[CI]:-0.38 to-0.14,P＜0.001),while positively associated with changes in WHtR in boys(β=0.003,95％CI:-0.0002 to 0.005,P=0.035).The 12-month follow-up changes in children's nutrition knowledge scores were positively associated with changes in children's WHtR(β=0.003,95％CI:0.0004 to 0.01,P=0.018).Conclusions:The intervention strategies did not reduce the BMI and WHtR of children,and the nutrition knowl-edge of children and parents increased after the intervention in intervention group.Changes in nutrition knowl-edge of children and their parents are associated with changes in children's BMI or WHtR.Interventions with a new focus on obesity are needed to help improve children's nutritional status in poverty-stricken areas in Shaanxi Province of China.
