ObjectiveTo investigate the temporal trend of weight-adjusted-waist index （WWI） and its association with the risk of incident cardiovascular diseases （CVD） among middle-aged and older Chinese adults. MethodsBased on the China Health and Retirement Longitudinal Study （CHARLS）， this research enrolled participants aged 45 and above with complete physical measurement data from the 2011， 2013， and 2015 waves. Complex sampling weights were applied to calculate the mean WWI， and the Mann-Kendall test was used to analyze its trend. From the 2011 baseline survey， individuals with a history of cardiovascular disease or missing key covariates were further excluded. New-onset cardiovascular outcome events were collected during follow-up until 2020. Participants were categorized into Q1–Q4 groups based on baseline WWI quartiles. Multivariable log-binomial regression models were constructed to assess the association between WWI and CVD， while restricted cubic splines were employed to evaluate potential nonlinear relationships. Sensitivity analyses were conducted to verify the robustness of the findings. ResultsFrom 2011 to 2015， the weighted mean WWI among Chinese middle-aged and older adults remained generally stable （2011： 11.17±1.68； 2013： 11.28±1.35； 2015： 11.24±1.59； P for trend <0.05）. During the longitudinal follow-up， 1 784 incident CVD cases were documented. After multivariable adjustment， each unit increase in WWI was associated with a 17% increased risk of CVD （RR： 1.17， 95%CI： 1.10-1.24）. Compared with the Q1 group， the risk of CVD in the Q2， Q3， and Q4 groups increased by 23% （RR： 1.23， 95% CI： 1.07-1.40）， 27% （RR： 1.27， 95% CI： 1.11-1.44）， and 40% （RR： 1.40， 95% CI： 1.22-1.60）， respectively. A significant linear trend was observed between the increasing WWI and elevated CVD risk （P for trend <0.001）. Subgroup analysis revealed a stronger association in participants aged 45-60 years （P for interaction <0.05）. The results of sensitivity analysis were consistent with the main research results. ConclusionsThe overall trend of WWI level in the middle-aged and elderly population in China is stable from 2011 to 2015. The higher level of WWI is associated with an increased risk of CVD， suggesting that WWI may be used as a simple and effective indicator to evaluate the risk of cardiovascular metabolism in middle-aged and elderly people.

ObjectiveTo investigate the incidence， glucolipid metabolism characteristics， and associated factors of postoperative overweight/obesity in children and adolescent with craniopharyngioma. MethodsA retrospective study was conducted using follow-up data from 44 patients （aged 0-18 years） diagnosed with craniopharyngioma who underwent surgical treatment and received follow-up care at Sun Yat-sen Memorial Hospital， Sun Yat-sen University， between January 2006 and February 2024. The incidence and glucolipid metabolism characteristics of overweight/obesity were summarized， and potential influencing factors were analyzed. ResultsA total of 44 patients were enrolled. The mean age at surgery was （8.57 ± 4.25） years， and the mean age at last follow-up was （16.02 ± 5.36 ）years. The mean follow-up duration was （7.45 ± 4.64） years （range， 8 months to 17.5 years）. The preoperative incidence of overweight/obesity was 40.91% （predominantly overweight， 27.27%）， which increased to 68.18% postoperatively （predominantly obesity， 50.00%）. Postoperatively， all patients （44/44， 100%） underwent fasting plasma glucose （FPG） testing， among whom 2 （4.55%） had impaired fasting glucose （IFG）. Fasting insulin （FINS） was measured in 20 patients， and insulin resistance was identified in 11 （55.00%）. Oral glucose tolerance testing （OGTT） with insulin release assessment was performed in 12 patients， and all （100%） exhibited abnormal insulin secretion， including 5 （41.67%） with hyperinsulinemia and 3 （25.00%） diagnosed with diabetes mellitus （DM）. All patients （44/44， 100%） underwent lipid profile assessment. The incidence of dyslipidemia was 81.82% （36/44）， including elevated non-high-density lipoprotein cholesterol （29/44， 65.91%）， hypertriglyceridemia （29/44， 65.91%）， low high-density lipoprotein cholesterol （22/44， 50.00%）， and mixed hyperlipidemia （13/44， 29.55%）. Logistic regression analysis indicated that preoperative overweight/obesity and postoperative abnormal glucose metabolism were significant factors associated with postoperative overweight/obesity. Compared with normal-weight patients， those with postoperative overweight/obesity had higher FINS levels （14.22 mU/L vs. 3.57 mU/L）， higher insulin resistance index（HOMA-IR） （2.88 vs. 0.52）， and a higher incidence of abnormal glucose metabolism （77.78% vs. 23.08%）. However， no significant difference was observed in the incidence of dyslipidemia （94.44% vs. 73.08%）. ConclusionsChildren and adolescent with craniopharyngioma exhibit a higher incidence of overweight/obesity than healthy peers preoperatively， which becomes more pronounced after surgery. This is accompanied by a high incidence of glucolipid metabolic disorders， placing these patients at increased risk of metabolic syndrome， which warrants clinical attention and regular metabolic assessment. In patients who develop postoperative obesity， particular attention should be given to the risk of glucose metabolism abnormalities， and further monitoring of glucose homeostasis is recommended.

Objectives:To investigate the physical growth status of pediatric patients with transfusion-dependent thalassemia (TDT) and analyze the effects of treatment-related and socioeconomic factors on physical growth.Methods:Based on the specialized thalassemia database from gene therapy clinical research at the Institute of Hematology & Hospital of Blood Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, we collected data on height and weight development, family economic status, and medical records of 338 pediatric patients with TDT from October 2023 to May 2024. The length/height-for-age and body mass index (BMI) -for-age were classified based on the Growth Standard for Children under 7 Years of Age, Standard for Height Level Classification among Children and Adolescents Aged 7-18 Years, and Dietary Guidelines for Chinese Residents. Logistic regression analysis was conducted to assess the effects of family economic status and disease-related treatment on length/height-for-age and BMI-for-age.Results:Among the 338 patients, 118 were children and 220 were adolescents (192 males and 146 females), with a median age of 12 years (range: 0.8-18) and a median diagnosis duration of 10.3 years (range: 0.5-17.9). Subtypes included α-thalassemia [21 cases (6.2%) ], β-thalassemia [288 cases (85.2%) ], and combined αβ-thalassemia[29 cases (8.6%) ]. The monthly household income of patients was concentrated in 3 000-5 000 yuan (39.9%) and 5 001-10 000 yuan (34.9%), whereas 67.2% of the families had monthly medical expenses of <3 000 yuan. Of the patients, 75.5% received their first transfusion before 1 year of age. The proportions of children and adolescents with pretransfusion hemoglobin (HGB) of ≤70 g/L were 4.2% and 6.4%, respectively. Adolescents demonstrated significantly higher rates of transfusion frequency of <4 weeks/session, monthly red blood cell infusion of >2 U, serum ferritin (SF) of ≥5 000 μg/L, iron chelation therapy, and splenectomy compared with children (all P<0.05). Of the 338 patients, 26.0%, 22.8%, and 8.9% demonstrated stunted growth, underweight, and concurrent stunted growth with underweight, respectively. No significant difference was observed in the stunted growth rates between children (22.9%) and adolescents (27.7%) ( P=0.402). However, the underweight rate in adolescents (26.8%) was significantly higher than that in children (15.3%) ( P=0.023). The multivariate analysis determined the following risk factors for stunted growth: monthly household income of <10 000 yuan (5 001-10 000 yuan: OR=5.49, 95% CI: 1.48-35.76; 3 000-5 000 yuan: OR=6.87, 95% CI: 1.88-44.60; <3 000 yuan: OR=9.29, 95% CI: 2.20-64.77), pretransfusion HGB of ≤70 g/L ( OR=3.25, 95% CI: 1.07-10.18), and SF of ≥5 000 μg/L ( OR = 3.04, 95% CI: 1.20-7.70). Longer diagnostic duration was associated with underweight ( OR=1.10, 95% CI: 1.01-1.20) . Conclusions:Children and adolescents with TDT with pretransfusion SF of ≥5 000 μg/L, HGB of ≤70 g/L, low monthly household income, or longer diagnosis duration were significantly more likely to experience delayed physical growth.

Objective:To expand the mutation spectrum of familial benign chronic pemphigus (HHD), and to deeply explore the relationship between clinical phenotypes and genotypes.Methods:HHD patients were retrospectively collected from the Department of Dermatology, Hospital for Skin Diseases, Shandong First Medical University from January 2018 to October 2023, and their clinical data and blood samples were also collected. Sanger sequencing and Whole-exome sequencing were performed on 34 HHD patients. Mutations in the ATP2C1 gene were classified into loss-of-function mutations (including frameshift mutations, nonsense mutations, and splicing mutations) and missense mutations. The relationship between clinical phenotypes and genetic mutation types was analyzed using Fisher's exact test or two-independent-sample t test, and further verified by meta-analysis. Results:The 34 HHD patients were all of Chinese Han nationality, including 20 males and 14 females, and their ages ranged from 35 to 77 years. Pathogenic mutations in the ATP2C1 gene were successfully identified in all the 34 patients, including 29 independent mutations, among which there were 9 frameshift mutations, 8 splicing mutations, 6 missense mutations, and 6 nonsense mutations. The age at onset was significantly earlier in the loss-of-function mutation group (37.62 ± 10.10 years) than in the missense mutation group (49.63 ± 14.90 years; t = 2.62, P = 0.013). However, there were no significant differences in gender, family history, disease seasonality, disease severity, or disease progression among patients with different mutation types (all P > 0.05). Meta-analysis showed that the age at onset was significantly earlier in Chinese Han patients with HHD carrying loss-of-function mutations than in those carrying missense mutations (mean difference: -4.61 years, 95% CI: -8.68 - -0.53 years, P = 0.030) . Conclusion:Chinese Han patients with HHD carrying loss-of-function mutations in the ATP2C1 gene showed significantly earlier ages at onset compared with those carrying missense mutations.

Objective To investigate the safety and efficacy of super-selective arterial embolization in the treatment of abdominal wall hematoma.Methods The clinical data of 11 patients with abdominal wall hematoma,who were admitted to the Northern Jiangsu People's Hospital of China from January 2018 to December 2023,were retrospectively analyzed.All patients received angiography together with super-selective arterial embolization.The effectiveness of embolization treatment was evaluated by the technical success rate and therapeutic effect,and the safety was evaluated by the incidence of complication.Results The median age of the 11 patients was 70 years,91％were female,with a body mass index(BMI)of 25.1 kg/m2,subcutaneous fat thickness of 2.8 cm,and international normalized ratio(INR)of 1.12.DSA showed that 8 patients(72％)had active bleeding signs,3 patients(28％)had no active bleeding signs.Under DSA,a total of 18 responsible vessels,including 6 lumbar arteries(33.3％),5 deep circumflex iliac arteries(27.7％),5 inferior epigastric arteries(27.7％)and 2 iliolumbar arteries(11.3％),were identified and were treated with embolization.The median time spent for operation was 80 minutes.The technical success rate was 100％and the clinical effective rate was 91％.No operation-related major complications occurred,and the median hospital stay was 6 days.Conclusion For the abdominal wall hematoma in aged,obesity patients with underlying diseases,super-selective arterial embolization is a therapeutic method with high technical success rate,high clinical effective rate and satisfactory clinical safety.

Objective To study the plasma metabolomics of mice poisoned by different dosage of the combination of diazepam and ethanol,and to reveal the toxicological mechanisms of combined poisoning of diazepam and ethanol.Methods Female Kunming mice were randomly divided into blank group,single and combined poisoning group(n=6),Based on the LD50 of diazepam co-administered with graded ethanol doses,mice in the single-drug and combined groups received oral gavage at 1/2,1,and 2 × LD50.Retro-orbital blood samples(～500 μL)were collected within 24 hours post-administration and analyzed by UPLC-QE-MS technology.Principal component analysis and orthogonal partial least squares discriminant analysis were used to identify differential metabolites and associated metabolic pathways.Results A total of 387 differential metabolites were identified in the combined poisoning group of diazepam and ethanol implicating the key pathways including tryptophan metabolism,phenylalanine metabolism,arginine and proline metabolism,Glycerophospholipid metabolism,phenylalanine,tyrosine and tryptophan biosynthesis.Conclusion Combined diazepam and ethanol poisoning exerts significant systemic effects by disrupting neurotransmitters conduction,exacerbating oxidative stress response and dysregulating energy metabolism.

Objective To explore the potential clinical value of the ratio of glycated albumin to albumin(GA/ALB)in the occurrence of heart failure(HF)among patients with coronary atherosclerotic heart disease(CHD).Methods A total of 337 CHD patients admitted to the Department of Cardiology in Shanxi Provincial People's Hospital from July 2023 to June 2024 were selected in this study.CHD patients were divided into HF group and non-HF group based on whether they progressed to HF.The clinical data and laboratory parame-ters of the two groups were compared.Restricted cubic spline curve was used to analyze the relationship be-tween GA/ALB levels and the risk of HF in CHD patients.Receiver operating characteristic curve was applied to evaluate the diagnostic efficacy of GA/ALB,GA,platelet to lymphocyte ratio(PLR),and monocyte to lym-phocyte ratio(MLR)in CHD patients with the occurrence of HF.Logistic regression was used to explore the relationship between serum GA/ALB levels and the risk of CHD patients occurrence of HF,and to analyze the degree of influence and stability of subgroup variables on results.Results There were statistically significant differences in GA/ALB,GA,PLR,MLR,and other indicators between the HF group and the non-HF group in CHD patients(P＜0.05).A non-linear relationship was observed between GA/ALB levels and the risk of HF in CHD patients.When the value of GA/ALB multiplied by 10 was less than 5.751,the risk of HF in CHD pa-tients increased with the increase of GA/ALB levels(P＜0.001).GA/ALB was an effective predictor for HF occurrence in CHD patients.Multivariable Logistic regression model showed that GA/ALB was an independ-ent risk factor for CHD patients with occurrence of HF.Subgroup analysis also confirmed the stability of GA/ALB in predicting the occurrence of HF in CHD patients.Conclusion GA/ALB is an independent risk factor for the occurrence of HF in CHD patients,and monitoring GA/ALB levels provides predictive value for the oc-currence of HF in these patients.
