OBJECTIVE: To observe the clinical efficacy of acupuncture based on the "head qijie" theory combined with endovascular intervention in the treatment of ischemic stroke (IS). METHODS: Sixty-six IS patients were randomly divided into an experimental group (33 cases, 3 cases dropped out) and a control group (33 cases, 3 cases dropped out). The control group received endovascular intervention. On the basis of the treatment in the control group, the experimental group received acupuncture based on the "head qijie" theory starting from the second day after surgery, Baihui (GV20) and bilateral Fengchi (GB20), Tianzhu (BL10), etc. were selected, once a day, 6 times a week for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Barthel index (MBI) and modified Rankin scale (mRS) were observed in the two groups, the clinical efficacy and safety were evaluated. RESULTS: After treatment, the NIHSS and mRS scores were decreased compared with those before treatment in both groups (P<0.01), the NIHSS and mRS scores in the experimental group were lower than those in the control group (P<0.05). After treatment, the MBI scores were increased compared with those before treatment in both groups (P<0.01), the MBI score in the experimental group was higher than that in the control group (P<0.05). The total effective rate in the experimental group was 86.7% (26/30), which was higher than 66.7% (20/30) in the control group (P<0.05). The incidence of adverse events in the experimental group was 6.7% (2/30), which was lower than 13.3% (4/30) in the control group (P<0.05). CONCLUSION Acupuncture based on the "head qijie" theory combined with endovascular intervention in treating IS has good efficacy, improves neurological function, and enhances daily living ability.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

Purpose To investigate the feasibility of multi-sequence MRI-based radiomics for predicting epidermal growth factor receptor(EGFR)mutation status in brain metastases from non-small cell lung cancer(NSCLC).Materials and Methods This retrospective study included 237 patients with NSCLC brain metastases from the Second Xiangya Hospital of Central South University(January 1,2017 to December 31,2023)who underwent EGFR genetic testing.All patients underwent pretreatment brain MRI including contrast-enhanced T1-weighted,T2-weighted FLAIR,and T2-weighted sequences,along with chest CT for primary lung lesions.EGFR mutations were identified in 120 patients.Using December 31,2021 as the cutoff date,patients were divided into training(n=146)and validation(n=91)cohorts.Senior radiologists delineated brain metastases on multi-sequence MRI and primary lesions on CT.A total of 851 radiomic features were extracted using PyRadiomics.Following feature selection,machine learning models were constructed using support vector machine algorithm and compared with least absolute shrinkage and selection operator-derived radiomic signatures.Five models were developed:three single-sequence MRI models,a multi-sequence MRI fusion model,and a CT model,with diagnostic performance evaluated by area under the receiver operating characteristic curve.Results The multi-sequence MRI fusion model demonstrated superior performance across all imaging types.The least absolute shrinkage and selection operator and support vector machine models achieved training set area under the curve of 0.854(95%CI 0.748-0.960)and 0.948(95%CI 0.923-0.973),respectively,and validation set area under the curve of 0.810(95%CI 0.751-0.869)and 0.951(95%CI 0.917-0.985),respectively.The optimal prediction model utilized support vector machine algorithm with multi-sequence MRI features.Conclusion Pretreatment multi-sequence MRI radiomics combined with machine learning accurately predicts EGFR mutation status in NSCLC patients with brain metastases.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

Objective To retrospectively analyze the characteristics of viral antibodies related to nervous system infections in patients with cognitive impairment,evaluate their relationship with cognitive impairment,and explore the relationship between viral infections and the occurrence and development of cognitive impair-ment.Methods A total of 170 mild cognitive impairment patients who visited Beijing Tiantan Hospital,Cap-ital Medical University from June 2019 to June 2023 were selected as the mild cognitive impairment group,208 cognitive impairment patients were selected as the cognitive impairment group,143 dementia patients were se-lected as the dementia group,and 146 age-matched and gender-matched non infectious and non inflammatory disease controls during the same period in the hospital were selected as the control group.The levels of virus antibodies related to nervous system infections in the serum and cerebrospinal fluid of patients were detected,the detection rate and levels of antibodies were compared,and the infection burden was calculated.The cogni-tive function of all patients was evaluated and the relationship between infection burden and the degree of cog-nitive dysfunction was analyzed.Results The detection rate and antibody level of herpes simplex virus(HSV)1 IgG in the serum of three groups of patients with cognitive impairment were significantly higher than those in the control group(P＜0.05).The detection rate of HSV(1+2)IgM in the serum of three groups of pa-tients with cognitive impairment was higher than that in the control group(P＜0.05),but there was no sta-tistically significant difference between the mild cognitive impairment group,cognitive impairment group,and dementia group(P＞0.05).The serum infection load of three groups of patients with cognitive impairment was higher than that of the control group(P＜0.05),and the higher the infection load,the more severe the cognitive impairment.Conclusion Viral infection is an important influencing factor of cognitive impairment diseases,and HSV infection may be a promoting factor of cognitive dysfunction.
