Objective To explore the incidence rate and related factors of dyslipidemia in children with simple obesity and overweight. Methods From October 2018 to December 2023, 254 children with simple obesity and overweight who received physical examination in the pediatric outpatient department of Beijing Jishuitan Hospital were selected as the observation group, and 46 healthy children during the same period were included in the control group. According to whether dyslipidemia occurred, children with simple obesity and overweight were classified into the dyslipidemia group (n=97) and the normal blood lipid group (n=157). Logistic regression analysis was used to analyze the related factors affecting dyslipidemia in children with simple obesity and overweight. Results The concentrations of total cholesterol (TC) and triglyceride (TG) of children in the observation group were significantly higher than those in the control group (P<0.05), while the level of high-density lipoprotein cholesterol (HDL-C) showed the opposite trend and was significantly lower than that in the control group (P<0.05). After logistic regression analysis, it was found that body mass index (BMI), fasting insulin level, alanine aminotransferase (ALT) activity, uric acid level, and daily sedentary time were related factors influencing dyslipidemia in children with simple obesity and overweight (P<0.05). Conclusion The incidence rate of dyslipidemia is high in children with simple obesity and overweight. BMI, fasting insulin level, ALT, uric acid level, and daily sedentary time are related factors of dyslipidemia in children with simple obesity and overweight.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the association between mouth breathing (MB) and functional speech sound disorders (FSSDs) in children, aiming to establish a novel theoretical basis for FSSD interventions.Methods:Eighty-nine children with an FSSD aged 4-12 years formed the FSSD group, while eighty-five age-matched healthy children served as controls. Their clinical data were processed using independent sample t-tests and chi-square tests to test for any significant differences between the two groups in terms of gender, age, mouth breathing status, post-frenotomy condition, Mandarin exposure before age 4, and delayed speech onset. Multivariate logistic regressions were evaluated to identify risk factors for FSSD in such children and to seek any association between mouth brea-thing and FSSD.Results:The regression analysis identified the following risk factors for childhood FSSD, ranked by odds ratio ( OR) magnitude: mouth breathing (adjusted OR=22.168, 95% CI=7.849-62.608, P≤0.01), delayed speech onset (adjusted OR=20.091, 95% CI=4.812-83.878, P≤0.01), age (a protective effect) (adjusted OR=0.979, 95% CI=0.962-0.997, P≤0.05). Univariate analysis of mouth breathing and associated factors revealed significant associations of FSSD with mouth breathing (χ 2=52.15, P≤0.01) and delayed speech onset (χ 2=25.873, P≤0.01). Conclusions:The significant risk factors for childhood functional speech sound disorders are mouth breathing (showing the highest adjusted OR), delayed speech onset and age. These findings suggest that early screening and therapeutic interventions for mouth breathing should be clinically prioritized to minimize FSSD risk.

Objective:To investigate the differences between high-frequency ultrasound-guided manual detorsion combined with surgery(MD+S)and surgery alone in the treatment of testicular torsion,and to provide some new evidence for the timely diagno-sis and treatment of the disease.Methods:We retrospectively analyzed the clinical data on 134 cases of unilateral testicular torsion within 48 hours treated in our hospital by MD+S or by surgery alone from January 2015 to May 2022.We statistically analyzed the age distribution,and duration and degrees of testicular torsion,followed by comparison between the two groups.Results:In the 134 ca-ses,the median age of onset was 15(13-19)years old,the median onset-to-visit time was 15(8-25)hours,and the median de-gree of torsion was 360°(180°-1080°).Of the total number of patients,21 underwent testicular excision and the other 113 were treated with the testis preserved,with no statistically significant difference in age distribution between the two groups(P＞0.05),and a higher rate of testis resection in those with longer duration and greater angle of torsion(P＜0.05).Totally,33 of the patients were assigned to the MD+S group and 101 to the surgery alone group.According to the actual clinical conditions and excluding those with torsion time longer than 24 hours and torsion angle greater than 720 °,28 of the patients underwent ultrasound-guided MD+S(with 1 case of testis resection,3.6％),and 68 received surgery alone(with 7 cases of testis resection,10.3％).The rate of testis resection was higher in the surgery alone than that in the MD+S group,but with no statistically significant difference between the two groups(P＞0.05),which was considered to be related to the small sample size in this study.Conclusion:The popularization of testicular torsion knowledge can shorten the onset-to-visit time,and reasonable manual detorsion before emergency surgery can reduce the rate of testis resection.

Objective To construct a nursing follow-up checklist for patients undergoing autologous hematopoietic stem cell transplantation,providing a basis for postoperative follow-up care.Methods Using evidence-based methods,the literature from major guide websites and databases using Chinese and English search terms was retrieved,and their quality was evaluated.The relevant items were extracted,and a first draft was formed.15 experts were selected in relevant fields from 14 tertiary hospitals in 13 provinces,cities,and autonomous regions across the country for Delphi inquiry.The nursing follow-up checklist was revised again based on expert opinions and clinical practice.The nursing follow-up checklist was initially applied and then revised again to form the final draft.Results 15 experts include 12 undergraduate and 3 master's degree holders.The positivity coefficients of the 2 rounds of inquiry were 100％;the authority coefficients of the experts were 0.815;the Kendall coefficients were 0.119 and 0.144,respectively;the differences were statistically significant(P＜0.001).The final nursing follow-up checklist was formed,which includes 6 primary indicators,including physiological status,psychological status,social and family support,living conditions,disease knowledge,and laboratory tests.19 patients(95％)found the follow-up content to be comprehensive.The follow-up nurses's satisfaction rate exceeded 85％.There were 27 secondary indicators and 61 tertiary indicators,with coefficients of variation of all indicators less than 0.25.Conclusion The nursing follow-up checklist is scientific,reliable,and practical,which can provide a basis for clinical nursing staff to follow up and comprehensively manage patients after autologous hematopoietic stem cell transplantation.

To summarize the nursing experience of 3 patients with severe hypercapnia during the acute exacer-bation of chronic obstructive pulmonary disease(COPD)undergoing extracorporeal carbon dioxide removal(ECCO2R),as well as adjustment of oxygen therapy support strategy and implementation of non-pharmacological airway clearance techniques.Additionally,the nursing focus includes all process nursing of ECCO2R,which covers the key aspects such as catheter selection and placement management,pre-flush setting and bubble handling,dual connection with initial parameter setting for patients,heparin pathway management and bleeding monitoring,observation of thrombosis formation and pressure monitoring during operation and self-examination,evaluation of carbon dioxide removal effi-ciency and implementation of decommissioning tests.After careful treatment and nursing,2 patients recovered and were discharged,and a patient's condition improved and was transferred to the respiratory ward for further treat-ment,and was discharged after 5 days.

Objective:To investigate the clinical efficacy of transcranial alternating current stimulation (tACS) combined with drug treatment in patients with bipolar Ⅰ disorder (BD Ⅰ).Methods:Forty-two patients with BD Ⅰ who were admitted to the Mental Health Center Affiliated to Anhui Medical University from March 2022 to June 2023 were included in this randomized double-blind study. These patients were randomly divided into a control group and an observation group using an Excel spreadsheet. In the control group, patients received 10 sessions of sham stimulation in addition to drug treatment, while the observation group received 10 sessions of tACS along with drug treatment. All patients were treated for 2 weeks. Each patient received stimulation for 15 minutes on each of the right and left prefrontal lobes once every working day. The Montreal Cognitive Assessment (MoCA) scores and Bech-Rafaelsen Mania Scale (BRMS) scores were compared between the two groups before and after treatment. Eighteen patients from the observation group and nineteen patients from the control group were included in the final analysis.Results:Two weeks after treatment, the MoCA score in the observation group was higher than that in the control group [(27.39 ± 1.88) vs. (24.63 ± 2.39)], and the BRMS score in the observation group was lower than that in the control group [(15.89 ± 3.18) vs. (19.00 ± 3.32)]. These differences were statistically significant ( t = -3.89, 2.91, both P < 0.05). After treatment, the MoCA score in the observation group increased, while the BRMS score decreased ( t = 5.04, -4.14, both P < 0.05). Pearson correlation analysis indicated the change in MoCA score was negatively correlated with BRMS score in both groups ( r = -0.433, P < 0.05). Conclusions:Drug treatment combined with tACS greatly improved clinical cognitive symptoms and reduced manic symptoms in patients with BD Ⅰ. The combined therapy exhibited better efficacy than monotherapy.

BACKGROUND:With the increasing demand for orthopedic implants,the search for materials with good biocompatibility and degradability has become a research hotspot.Magnesium-lithium-gadolinium(Mg-Li-Gd)alloy has good degradability,biocompatibility,and mechanical properties,providing ideal supporting conditions for fracture healing.OBJECTIVE:To evaluate the effects of Mg-Li-Gd alloy implants on bone healing in rats.METHODS:A circular half-defect model was made on the lateral side of the right mid-femoral segment in 28 SD rats,and the rats were randomly divided into two groups.The stainless steel group was fixed with a stainless steel intramedullary nail,and the magnesium alloy group was fixed with an Mg-Li-Gd alloy intramedullary nail,with 14 rats in each group.At 2,8,and 14 weeks after surgery,right femur X-ray and Micro-CT examinations,as well as hematoxylin-eosin staining,immunohistochemical staining,and western blot assay were performed.RESULTS AND CONCLUSION:(1)X-ray film:At 2 weeks after surgery,the osteotomy lines of both groups were clear,the density of the intramedullary nail in the magnesium alloy group was close to that of bone tissue,and the density of the intramedullary nail in the stainless steel group was higher than that of bone tissue.At 8 weeks after surgery,the osteotomy lines of both groups were blurred,and the intramedullary nail in the magnesium alloy group had corroded and degraded.At 14 weeks after surgery,the osteotomy lines of both groups disappeared,and the intramedullary nail in the magnesium alloy group further corroded and degraded.(2)Micro-CT:At 2 weeks after surgery,callus began to form in both groups;8 weeks after surgery,the stainless steel group entered the callus remodeling stage,and a relatively dense bone structure was formed at the bone defect site,and the magnesium alloy group showed obvious callus hyperplasia at the bone defect site.At 14 weeks after surgery,the stainless steel group showed a mature bone remodeling process,and thick cortical bone was formed at the bone defect site,and thinner cortical bone was formed in the magnesium alloy group.(3)Hematoxylin-eosin staining:At 2 weeks after surgery,a large number of osteoblasts,osteocytes,a small number of osteoclasts and trabecular structures were observed in the magnesium alloy group,while relatively few osteoblasts and osteocytes were observed in the stainless steel group.At 8 weeks after surgery,a large number of osteoblasts,osteocytes,and mature trabecular structures were observed in the magnesium alloy group,while a large number of osteocytes and lamellar bones were observed in the stainless steel group.At 14 weeks after surgery,lamellar bones were observed in the magnesium alloy group,while mature bone tissue was observed in the stainless steel group.(4)Immunohistochemical staining and western blot assay:At the same time point,the expression levels of bone morphogenetic protein 2,osteocalcin,and RUNX2 proteins in the magnesium alloy group were higher than those in the stainless steel group.(5)The results showed that compared with stainless steel materials,Mg-Li-Gd alloy had no obvious advantage in promoting the formation of fracture healing structure.

Cardiovascular diseases have become the leading cause of mortality worldwide.The gut microbiota and its metabolites play an important role in the occurrence and development of cardiovascular diseases,and an imbalance of gut microbiota and its metabolites can promote the progression of cardiovascular diseases.Phenylacetylglutamine is a phenyl-alanine metabolite of intestinal flora.More and more studies have shown that phenylacetylglutamine is an independent risk factor of cardiovascular diseases and a potential biomarker of cardiovascular diseases.It is involved in the pathogenesis of cardiovascular diseases,such as arrhythmia,heart failure,atherosclerosis,etc.Therefore,interventions targeting pheny-lacetylglutamine are expected to become a new strategy for treating cardiovascular diseases.This review focuses on the role of phenylacetylglutamine in the occurrence and development of several common cardiovascular diseases.

Objective:To introduce the clinical application of "page-turning" superior pancreatic lymph node dissection in laparoscopic D2 radical gastrectomy for gastric cancer.Methods:Patients who were confirmed to have adenocarcinoma by preoperative gastroscopy and pathological biopsy, with tumor staging evaluated by imaging as cT1~4aN0~3M0, without neoadjuvant therapy, and without absolute surgical contraindications, underwent laparoscopic radical gastrectomy for gastric cancer with "page-turning" superior pancreatic lymph node dissection. The "page-turning" superior pancreatic lymph node dissection was performed in four steps: (1) Expose the posterior gastric mesentery and dissect No.11p lymph nodes; (2) Expose the left gastric mesentery and dissect No.7, No.8a and No.9 lymph nodes; (3) Expose the right gastric mesentery and dissect No.5 lymph nodes; (4) Expose the left edge of the portal vein and dissect No.12a lymph nodes.Results:From April 2018 to October 2024, 112 patients with gastric cancer underwent laparoscopic D2 radical gastrectomy with "page-turning" superior pancreatic lymph node dissection, including 21 cases in the First Affiliated Hospital of Guangzhou University of Chinese Medicine, 78 cases in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and 13 cases in the Department of Gastrointestinal Surgery, Jilin Provincial People's Hospital. The TNM staging of all patients was as follows: 31 cases in stage Ⅰ, 24 cases in stage Ⅱ, and 57 cases in stage Ⅲ; 62 cases of differentiated adenocarcinoma and 50 cases of undifferentiated adenocarcinoma; the median length of tumors was 3.8 cm. All patients successfully completed the operation without conversion to open surgery, no intraoperative massive hemorrhage or postoperative death. The median total number of lymph nodes dissected in all patients was 32, and the median number of positive lymph nodes was 4.5. The overall postoperative complication rate was 5.4% (6/112), all of which were Clavien-Dindo grade Ⅱ, including pulmonary infection, pleural effusion, and incisional infection, all cured by symptomatic treatment. The median follow-up was 41.8 (2-78) months, with 7 cases lost to follow-up. During the follow-up period, 27 cases (25.7%) had tumor recurrence and 16 cases (15.2%) died.Conclusions:The "page-turning" superior pancreatic lymph node dissection technique is safe and feasible in laparoscopic radical gastrectomy for gastric cancer.
