Diabetes is a very complex endocrine disease whose common feature is the increase in blood glucose concentration. Persistent hyperglycemia can lead to blindness, kidney and heart disease, neurodegeneration, and many other serious complications that have a significant impact on human health and quality of life. The number of people with diabetes is increasing yearly. The global diabetes prevalence in 20-79 year olds in 2021 was estimated to be 10.5% (536.6 million), and it will rise to 12.2% (783.2 million) in 2045. The main modes of intervention for diabetes include medication, dietary management, and exercise conditioning. Medication is the mainstay of treatment. Marketed diabetes drugs such as metformin and insulin, as well as GLP-1 receptor agonists, are effective in controlling blood sugar levels to some extent, but the preventive and therapeutic effects are still unsatisfactory. Peptide drugs have many advantages such as low toxicity, high target specificity, and good biocompatibility, which opens up new avenues for the treatment of diabetes and other diseases. Currently, insulin and its analogs are by far the main life-saving drugs in clinical diabetes treatment, enabling effective control of blood glucose levels, but the risk of hypoglycemia is relatively high and treatment is limited by the route of delivery. New and oral anti-diabetic drugs have always been a market demand and research hotspot. Inhibitor cystine knot (ICK) peptides are a class of multifunctional cyclic peptides. In structure, they contain three conserved disulfide bonds (C3-C20, C7-C22, and C15-C32) form a compact “knot” structure, which can resist degradation of digestive protease. Recent studies have shown that ICK peptides derived from legume, such as PA1b, Aglycin, Vglycin, Iglycin, Dglycin, and aM1, exhibit excellent regulatory activities on glucose and lipid metabolism at the cellular and animal levels. Mechanistically, ICK peptides promote glucose utilization by muscle and liver through activation of IR/AKT signaling pathway, which also improves insulin resistance. They can repair the damaged pancrease through activation of PI3K/AKT/Erk signaling pathway, thus lowering blood glucose. The biostability and hypoglycemic efficacy of the ICK peptides meet the requirements for commercialization of oral drugs, and in theory, they can be developed into natural oral anti-diabetes peptide drugs. In this review, the structural properties, activity and mechanism of ICK pattern peptides in regulating glucose and lipid metabolism were summaried, which provided a reference for the development of new oral peptides for diabetes.

Objective:
To evaluate the effects of problem-oriented respiratory rehabilitation nursing on lung function, activity ability, length of hospital stay, and retention time of closed chest drainage tube in patients undergoing thoracoscopic radical resection for lung cancer, so as to provide a basis for improving the prognosis of patients with lung cancer surgery.
Methods:
A total of 119 patients with lung cancer who underwent thoracoscopic radical resection for lung cancer in the First Affiliated Hospital of Anhui Medical University from October 2023 to June 2024 were selected and randomly divided into the intervention group (n=59) and the control group (n=60). The control group received routine respiratory rehabilitation nursing of thoracic surgery. On the basis of the treatment and guidance received by the control group, the intervention group implemented problem-oriented respiratory rehabilitation nursing. First second expiratory volume (FEV1) and forced vital capacity (FVC) were used to evaluate pulmonary function at 1 day before surgery and 3 days after surgery, and the 6-minute walk distance (6MWD) was used to evaluate physical activity. The incidence of pulmonary complications, length of hospital stay and retention time of closed chest drainage tube were collected through the hospital's electronic medical records system. The intervention effects between the two groups were compared using variance analysis of repeated-measures analysis of variance and log-rank test.
Results:
The mean age of the control group was (60.77±9.31) years, with 28 males and 32 females. There were 4 cases of squamous cell carcinoma, 55 cases of adenocarcinoma, and 1 case of small cell carcinoma. The tumors were located in the right lobe in 41 cases. The mean age of the intervention group was (58.71±10.01) years, with 23 males and 36 females. There were 2 cases of squamous cell carcinoma, 56 cases of adenocarcinoma, and 1 case of small cell carcinoma. The tumors were located in the right lobe in 37 cases. There were no statistically significant differences in age, gender, education level, pathological type, and tumor location between the two groups (all P>0.05). Three days after surgery, there was an interaction effect between the group and the time in FEV1, FVC, and 6MWD between the two groups. The FEV1 and 6MWD in the intervention group were higher than those in the control group (both P<0.05). There was no statistically significant difference in FVC between the groups (P>0.05). There were 3 cases of postoperative complications in the control group, and no cases in the intervention group. Log-rank test showed that the length of hospital stay and retention time of closed chest drainage tube after surgery in the intervention group were shorter than those in the control group (both P<0.05).
Conclusion
The problem-oriented respiratory rehabilitation nursing can improve the lung function and activity ability of patients with lung cancer after surgery, shorten the length of hospital stay and retention time of closed chest drainage tube, and improve the quality of life.

Objective:
To analyze the status and correlation between screen time, screen behavior type, and anxiety, depression among children and adolescents in Jiangxi Province, so as to provide a basis for effective intervention measures.
Methods:
Using the method of stratified random sampling, 8 851 primary and secondary school students in 11 districts of Jiangxi Province were investigated by questionnaire during September to December in 2020. Anxiety and depression status were investigated using the State Trait Anxiety Inventory (STAI) and the Center for Epidemiological Studies Depression Scale for Children(CES-DC), respectively. Single factor analysis using χ 2-test, t-test,analysis of variance,and multivariate analysis using generalized linear models.
Results:
On school days and weekends, 4.7% and 20.4% of primary and secondary school students in Jiangxi Province had a total screen time of over 2 hours per day, respectively. The weighted scores of the total screen time (primary school students: 1.88± 0.68, junior middle school students: 1.96±0.71, high school students: 2.03±0.80) and time spent for playing video games (primary school students: 1.51±0.64, junior middle school students: 1.62±0.69, high school students: 1.68±0.75) daily showed an upward trend with the increase of educational stage ( F =31.48, 42.13), and with significantly higher in boys (1.97±0.74, 1.66± 0.72) than girls (1.93±0.72, 1.53±0.66)( t =2.48, 9.07)( P <0.05). The average scores of state anxiety and trait anxiety were (42.20±9.05) and (40.65±9.85), which showed an upward trend with the increase of educational stage ( F =168.12, 241.98 ), and were higher in girls than boys ( t =6.63, 8.48)( P <0.01). The average score of depression was (11.99±11.00), which was lower in elementary school students than middle school students and high school students ( F =136.42), with significantly higher in girls ( t =6.85)( P <0.01). On school days, with the increase of total screen time and time spent for playing video games daily, the risk of state anxiety, trait anxiety, and depression among primary and secondary school students significantly increased ( OR = 6.70- 818.98, P <0.01). On weekends, among primary and secondary school students, the total screen time of >1-2 hours daily reduced the risk of state anxiety ( OR =0.30). The risk of developing trait anxiety among students playing video games for more than 2 hours daily was 2.50 times higher than those without screen behavior ( OR =2.50). The risk of developing depression with a total screen time of more than 2 hours daily was 3.15 times higher those whithout screen behavior ( OR =3.15). The risk of developing depression among students playing video games >0-1, >1-2, >2 h daily was 2.14, 2.50, 4.90 times that of those without screen behaviors ( OR =2.14, 2.50, 4.90), and showed an upward trend with the increase of educational stage ( P <0.05).
Conclusions
Screen behaviors of primary and middle school students in Jiangxi Province are positively associated with the risk of anxiety and depression, but the total daily video time of >1-2 h on weekends was negatively associated with state anxiety. It is necessary to control the screen time as much as possible and reduce the risk of anxiety and depression.
