Objective: To systematically evaluate the effect of exercise intervention on lipid metabolism among overweight or obese children and adolescents, providing evidence for improving lipid metabolism. Methods: Literature were retrieved and screened from PubMed, Web of Science, Cochrane Library, EBSCO, Embase, CNKI, Wanfang, and VIP databases regarding the impact of exercise intervention on lipid metabolism among overweight or obese children and adolescents, with a search period from 1,January 2000 to 30,April 2025. Data extraction and quality assessment of included studies were performed, and network Meta analysis was conducted by using RevMan 5.3 and Stata 18.0 software, with standardized mean difference (SMD) and 95% CI as the effect measures. Results: A total of 15 eligible randomized controlled trials were included, with 13 reporting outcomes for total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), and 14 for triglycerides (TG) and high density lipoprotein cholesterol (HDL-C). Network Meta analysis results showed that compared with the control group, aerobic exercise (AE) ( SMD = -0.51, 95% CI =-0.97 to -0.06) and combined aerobic and resistance exercise (COM) ( SMD =-0.54, 95% CI =-1.03 to -0.05) effectively reduced TC levels; AE ( SMD =-0.98, 95% CI =-1.64 to -0.32) and high intensity interval training (HIIT) ( SMD =-1.58, 95% CI = -2.52 to -0.64) effectively reduced TG levels; AE ( SMD =-0.60, 95% CI =-1.05 to -0.14), COM( SMD =-1.10, 95% CI =-1.72 to -0.48) and HIIT ( SMD =-1.05, 95% CI =-1.68 to -0.43) all effectively reduced LDL-C levels; only HIIT ( SMD = 1.03 , 95% CI =0.05-2.00) significantly increased HDL-C levels(all P <0.05). Conclusions Exercise intervention is beneficial to improve the dyslipidemia among children and adolescents, and the intervention effects of different exercise on different types of dyslipidemia are different.

Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

Current experimental and computational methods have limitations in accurately and efficiently classifying ion channels within vast protein spaces. Here we have developed a deep learning algorithm, GPT2 Ion Channel Classifier (GPT2-ICC), which effectively distinguishing ion channels from a test set containing approximately 239 times more non-ion-channel proteins. GPT2-ICC integrates representation learning with a large language model (LLM)-based classifier, enabling highly accurate identification of potential ion channels. Several potential ion channels were predicated from the unannotated human proteome, further demonstrating GPT2-ICC's generalization ability. This study marks a significant advancement in artificial-intelligence-driven ion channel research, highlighting the adaptability and effectiveness of combining representation learning with LLMs to address the challenges of imbalanced protein sequence data. Moreover, it provides a valuable computational tool for uncovering previously uncharacterized ion channels.

Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.

Objective To investigate the expression levels of scf and c-kit under the regulation of Dahuang Lingxian prescription and the possible mechanism of its effect on gallbladder dynamics, and to provide a theoretical basis for Dahuang Lingxian prescription in preventing the development and recurrence of cholesterol gallstone. Methods A total of 45 specific pathogen-free healthy male guinea pigs were randomly divided into normal group, model group, and traditional Chinese medicine (TCM) group. The guinea pigs in the normal group were fed with normal diet, and those in the model group and the TCM group were fed with high-fat lithogenic diet. After 8 weeks of feeding, 5 guinea pigs were randomly selected from each group, and successful modeling was determined if gallstone was observed with the naked eye in more than 4 guinea pigs. After successful modeling, the guinea pigs in the TCM group were given Dahuang Lingxian prescription by gavage, and those in the model group were given an equal volume of normal saline by gavage. After 8 consecutive weeks of administration by gavage, gallbladder tissue samples were collected, and HE staining was used to observe the pathological changes of gallbladder tissue; Western blot was used to measure the expression level of tumor necrosis factor-α (TNF-α) in gallbladder tissue; immunohistochemistry was used to measure the protein expression levels of scf and c-kit in gallbladder smooth muscle tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference multiple comparison method was used for further comparison between two groups. Results HE staining showed marked inflammation of gallbladder tissue in the model group, and compared with the model group, the TCM group had a significantly lower degree of inflammation. Western blot showed that the model group had the highest expression level of TNF-α in gallbladder tissue, followed by the TCM group and the normal group ( P < 0.05); immunohistochemistry showed that compared with the model group, the normal group and the TCM group had significantly higher protein expression levels of scf and c-kit in gallbladder smooth muscle tissue ( P < 0.05). Conclusion Dahuang Lingxian prescription can enhance the dynamic function of the gallbladder, possibly by upregulating the scf/c-kit signaling pathway in interstitial cells of Cajal in gallbladder.

Objective:To investigate and compare the therapeutic effect of Foley catheter balloon dilation and the traditional open reduction in the treatment of intussusception in children.Methods:A total of 68 children with intussusception treated by Foley catheter balloon dilatation by laparoscopic surgery or traditional open reduction in Department of Pediatric Surgery, the Second Hospital of Lanzhou University from August 2015 to July 2019 were retrospectively analyzed.Among them, there were 32 cases in the Foley catheter group and 36 cases in the traditional laparotomy group.Foley catheter group were treated with laparoscopic Foley catheter balloon dilatation, while the traditional open group were treated with traditional open surgery which was performed with finger dilatation.The results of surgical treatment, postoperative recovery, short-term complications, patient satisfaction and long-term complications were compared between the two groups.Results:Among the indexes of surgical treatment effect, the operation time[(0.4±1.1) h], intraoperative bleeding volume[(10.2±3.4) mL], incision size[(0.5±0.4) cm] and incidence of the rupture of intestine[6.3%(2/32 cases)] in the Foley catheter group were significantly lower than those in the traditional open group[(1.3±2.9) h, (40.5±2.1) mL, (5.1±0.7) cm, 30.6%(11/36 cases)], and the differences were statistically significant (all P< 0.05). Among the indexes of postoperative recovery and short-term complications, recovery time of gastrointestinal function[(1.2±3.1) d], length of hospital stay[(6.7±1.8) d], incidence of incision infection[9.4%(3/32 cases)]and incidence of incisional hernia(0) in the Foley catheter group were significantly lower than those in the traditional open group[(3.3±6.4) d, (7.3±0.9) d, 36.1%(13/36 cases), 16.7%(6/36 cases)], and the differences were statistically significant (all P<0.05). Among the indexes of family satisfaction and long-term complications, the score of family satisfaction in the Foley catheter group [(8.7±1.2) scores]was significantly higher than that in the traditional open group[(6.6±3.1) scores], and the incidence of adhesive intestinal obst-ructionin the Foley catheter group (0)was significantly lower than that in the traditional open group[0 vs.19.4%(7/36例)], and the differences were statistically significant(all P<0.05). Conclusions:Compared with traditional open reduction in the treatment of intussusception in children, Foley catheter balloon dilation has the advantages of short operation time, safe operation, low incidence of intestinal injury, less bleeding, and so on, and also has the advantages of small incision, fast recovery, short hospitalization time, high satisfaction of parents.In addition, the Foley catheter balloon dilation has a lower incidence of incisional infection, incisional hernia, postoperative intestinal adhesion and other complications.
