Objective:To summarize the clinical characteristics of focal cerebral arteriopathy (FCA) in children, and to analyze its influencing factor of prognosis.Methods:A retrospective cohort study was conducted. Clinical data from 40 children with FCA who were hospitalized at the Department of Neurology, Beijing Children′s Hospital, Capital Medical University, from September 2015 to August 2024 were collected. A centralized follow-up was conducted in October 2024 via outpatient clinics or the internet. The pediatric stroke outcome measure (PSOM) was used to evaluate their outcomes. Based on the PSOM, the children were further divided into a group with normal neurological function and another group with abnormal neurological function. Differences between groups were analyzed using the Mann-Whitney U test and Fisher exact test. Univariate Logistic regression analysis was performed to identify the influencing factors for neurological outcomes in children with FCA. Results:A total of 40 children were included, with 20 males and 20 females, and the onset age of 9.2 (6.8, 12.5) years. Among them, 12 cases (30%) had a history of varicella within 1 year before onset. There were 23 cases (58%) presenting with transient ischemic attack (TIA) or recurrent fluctuating symptoms of onset, while 3 cases (8%) developed progressive stroke within the first month of onset. The M1 segment of the middle cerebral artery was the most commonly affected vascular site, with a total of 16 cases (40%). Arterial occlusion occurred in 8 cases (20%). Lumbar puncture was completed in 36 children, and white blood cell counts in cerebrospinal fluid was increased in 6 cases. All 23 patients who completed magnetic resonance vessel wall imaging (VWI) showed circular enhancement of the arterial wall. A total of 28 patients (70%) received antiplatelet or anticoagulation therapy, and 16 patients (40%) received hormone therapy. At admission, the pediatric National Institute of Health Stroke Scale (PedNIHSS) score was 6.0 (2.0, 8.8) points, which decreased to 0.5 (0, 3.0) points at discharge. The follow-up duration was 1.6 (0.8, 4.9) years, with 1 case lost to follow-up. There was 1 case presenting with recurrence course manifesting as TIA. Among the 39 cases who completed the follow-up, 23 cases (59%) were assessed as neurologically normal by PSOM, while 16 cases (41%) were assessed as neurologically abnormal. Among the 29 cases who completed the imaging review, magnetic resonance angiography (MRA) review in 23 cases indicated stability or improvement in the original arterial stenosis, with 6 cases experiencing transient worsening of arterial stenosis early in the disease course (within 2 months), which later improved. Arterial stenosis progression occurred in 6 cases at the final review of 29 cases who completed the imaging review, with 1 case developing progressive cerebral arteriopathy. The proportion of patients with headache, altered consciousness, and aphasia in the abnormal neurological function group, as well as the PedNISS scores at admission and discharge, were all higher than those in the normal neurological function group (all P<0.05). Univariate Logistic regression analysis revealed that only a PedNISS score>6 points at onset was an influencing factor for abnormal neurological function ( OR=20.58, 95% CI 3.93-107.70, P<0.001). Conclusions:Childhood FCA often presents with fluctuating onset, and the proximal segment of the middle cerebral artery is frequently affected. Progression of arterial stenosis is common within 2 months of the disease course, but clinical progression and new ischemic lesions are uncommon. Most patients have a favorable long-term prognosis. PedNIHSS score>6 points at admission is related to abnormal neurological function outcomes.

Objective The causal relationship between endometriosis(EMs)and 15 trace elements including copper,calcium,carotene,folic acid,iron,magnesium,potassium,selenium,vitamin A,vitamin B12,vitamin B6,vitamin C,vitamin D,vitamin E and zinc was analyzed by double sample Mendelian randomization(MR).Methods Multiple trace elements were used as exposure factors,and the incidence risk of EMs was used as the outcome factor for two-sample MR analysis.The data were sourced from the publicly available integrative epidemiology unit open Genome-Wide Association Studies database and Finnish Genome Research Project database.Five Mendelian randomization analysis methods were employed to investigate the causal relationship between EMs and trace elements.Additionally,sensitivity analysis was carried out to evaluate the influence of heterogeneity and horizontal pleiotropy on the results of the MR analysis.Results The impact of trace elements on various types of EMs varies.The results of the inverse variance weighted(IVW)method indicated that trace element calcium(OR=1.465,95％CI:1.094-1.962)and vitamin B6(OR=1.580,95％CI:1.146-2.178)might be risk factors for ovarian EMs.Vitamin B6(OR=0.203,95％CI:0.044-0.939)may be a protective factor for tubal EMs.The above research results were not affected by heterogeneity and horizontal pleiotropy(P＞0.05).This study did not find a causal relationship between other trace elements and EMs.Conclusion The trace elements calcium and vitamin B6 predicted by genetics may play a regulatory role in the development of EMs.

Metabolic associated fatty liver disease(MAFLD)is a type of fatty liver disease associated with systemic metabolic disorders,and its prevalence has been increasing year by year,becoming a major challenge to global public health.The development of MAFLD is associated with various factors,including obesity,dyslipidemia,diabetes and other factors.Excessive body fat,particularly increased visceral adiposity,contributes to hepatic fat accumulation.Abnormal blood lipid levels can also disrupt liver fat metabolism.The risk of MAFLD in patients with diabetes is greatly increased due to insulin resistance and other problems.Dietary interventions are considered an effective strategy for the prevention and treatment of MAFLD.In recent years,several dietary patterns,such as low-carbohydrate diets,intermittent fasting,and the Mediterranean diet,have been applied in clinical practice.Their primary mechanisms include reducing oxidative stress,regulating gut microbiota,and inducing fat autophagy.However,the responses to different dietary patterns vary among individuals due to differences in genes,lifestyle,and disease severity.Therefore,systematically evaluating the effects and mechanisms of these dietary patterns in the prevention and treatment of MAFLD has significant clinical importance.This review compares the effects of different dietary patterns on improving liver function,hepatic fat content,blood glucose,and lipid levels,and analyzes their underlying mechanisms of intervention,to explore how to select personalized dietary strategies based on individual differences.It is intended to provide new insights for the precise prevention and treatment of MAFLD,thereby improving patients' outcomes and alleviating the burden on public health.

Objective:To investigate the early clinical outcomes of anterior cervical discectomy and fusion (ACDF) in the treatment of two-segment cervical spondylotic myelopathy (CSM) using a cervical soft endoscopic minimally invasive system.Methods:A retrospective follow-up study was conducted on the medical records of 23 patients with two-segment cervical myelopathy who underwent ACDF using a soft endoscopic cervical spine minimally invasive system at the Third Affiliated Hospital of Southern Medical University between October 2022 and December 2023. The cohort included 15 males and 8 females, aged 37-79 years (58.52±11.77 years). The affected cervical segments included: C 3, 4 and C 4, 5 in 2 cases; C 3, 4 and C 5, 6 in 3 cases; C 4, 5 and C 5, 6 in 10 cases; C 5, 6 and C 6, 7 in 7 cases; and C 4, 5 and C 6, 7 in 1 case. Clinical outcomes were evaluated based on the Japanese Orthopaedic Association (JOA) scores and visual analog scale (VAS) for neck and shoulder pain, assessed preoperatively and at 1 week, 1 month, and 3 months postoperatively. Additional data recorded included incision length, intraoperative blood loss, operative time, postoperative complications, and the presence of prevertebral soft tissue edema. The improvement rate of JOA scores at the final follow-up was also calculated. Results:All patients successfully underwent surgery and completed follow-up, with follow-up durations ranging from 3 to 6 months (4.01±0.98 months). The mean operative time was 80.09±22.66 min (range: 53-127 min), and the mean incision length was 3.25±0.32 cm (range: 3-4 cm). Estimated blood loss ranged from 10 to 100 ml, with a mean of 34.78±24.1 ml. Postoperative drainage ranged from 0 to 80 ml (mean: 23.13±26.1 ml), and postoperative hospitalization durations ranged from 4 to 12 days (6.83±2.59 days). JOA scores improved significantly from a preoperative median of 9.00(8.00, 10.00) to 12.00(11.00, 14.00) at 1 week, 13.00(12.00, 14.00) at 1 month, and 15.00(15.00, 16.00) at 3 months postoperatively (χ 2=220.492, P<0.001). VAS scores for neck and shoulder pain also improved significantly from a preoperative median of 5.00(4.00, 6.00) to 3.00(2.00, 3.00) at 1 week, 2.00(2.00, 3.00) at 1 month, and 2.00(1.00, 2.00) at 3 months postoperatively (χ 2=170.869, P<0.001). No postoperative complications such as dysphagia, hoarseness, nerve injury, cerebrospinal fluid leakage, or intraspinal hematoma were observed. Imaging revealed no significant prevertebral soft tissue edema. At the final follow-up, the improvement rate of JOA scores resulted in 14 cases rated as excellent and 9 as good. Conclusions:ACDF using a cervical soft endoscopic minimally invasive system demonstrates satisfactory clinical outcomes for the treatment of two-segment CSM. This technique reduces the incidence of common complications associated with both open and traditional endoscopic surgeries.

As a novel long-acting glucagon-like peptide-1 （GLP-1） receptor agonist， semaglutide plays a pivotal role in the treatment of obesity and related metabolic diseases. This article systematically reviews the research progress of semaglutide in the treatment of obesity and related metabolic diseases from three aspects： mechanism of action， clinical applications， and existing challenges. It is found that its mechanism of action involves multi-organ synergistic regulation and metabolic intervention. Its clinical applications encompass the treatment of obesity， diabetes， polycystic ovary syndrome， and liver-related metabolic syndromes， and it demonstrates groundbreaking value in cardiovascular and renal protection. However， it still faces multiple challenges in terms of adverse reactions， individualized treatment， economic accessibility， ethical controversies， and risks. In the future， it is essential to further accumulate long-term safety data on semaglutide， optimize combination treatment regimens， and address key issues such as individualized medication for special populations， in order to fully realize its clinical application value.

Objective To investigate the relationship between different interleukins (ILs) and gynecological tumors, including cervical cancer, endometrial cancer, and uterine leiomyoma using two-sample Mendelian randomization (MR) analysis. Methods IL and gynecological tumor data were obtained from European populations by using the IEU OpenGWAS open database. Two-sample MR analysis was applied, different interleukins were used as exposure factors, significant SNP in GWAS data were selected as instrumental variables, and the instrumental variables were independent of each other. The risk of three kinds of gynecological tumors was analyzed separately to explore the causal relationship between ILs predicted by genes and outcome indicators. The TwoSampleMR package in R language (4.3.1) software was used for statistical analysis. MR analysis was performed using inverse variance weighted, MR Egger regression, weighted median, simple mode, and weighted mode methods. Results IL-18 receptor 1 (P=0.039) and IL-24 (P=0.025) were negatively correlated with the risk of cervical cancer. IL-4 (P=0.040), IL-21 (P=0.026), and IL-37 (P=0.027) were positively correlated with the risk of endometrial cancer. IL-15 receptor subunit alpha (P=0.005) was negatively correlated with the risk of endometrial cancer. IL-17A (P=0.005) and IL-37 (P=0.018) were negatively correlated with the risk of uterine leiomyoma. IL-21 (P=0.035) was positively correlated with the risk of uterine leiomyoma. Conclusion Genetically predicted IL-4, IL-15Rα, IL-17A, IL-18R1, IL-21, IL-24, and IL-37 are causally associated with the risk of three gynecological tumors. Further exploration of the molecular mechanism of ILs in gynecological tumors may provide potential therapeutic targets for the treatment of gynecological tumors.

Objective To conduct an analysis on objective data of tongue manifestations and complexions among college students with yang deficiency constitution and balanced constitution,thus to explore the correlation between yang deficiency constitution and the objective data of tongue manifestations and complexions among college students.Methods From August 2023 to January 2024,data collection was carried out in 325 cases of yang deficiency constitution(yang deficiency group)and 175 cases of balanced constitution(balanced group)from college students of Hunan University of Chinese Medicine,Central South University,Hunan Normal University,Hunan University and Changsha University of Science and Technology in Hunan Province.YM-MA-Ⅰ digital detection system for tongue manifestations and complexions of traditional Chinese medicine(TCM)was utilized for data collection and image analysis,and the differences in the Lab parameters of tongue color,tongue shape,tongue coating color,complexions,and lip color were compared between yang deficiency group and balanced group.Of the Lab parameters,letter"L"stands for luminance,which expresses the luminance from absolute black to absolute white,and takes the value of 0-100;letter"a"and letter"b"stand for two color channels,letter"a"represents the color from dark green to grey then to bright pink,and takes a value from-128 to 127,and letter"b"represents the color from bright blue to grey then to yellow,and also takes a value from-128 to 127.Results(1)The analysis of tongue manifestations showed that in comparison with the balanced group,enlarged tongue(72.62％),tooth-marked tongue(83.69％),and greasy coating(59.38％)were frequently seen in the yang deficiency group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(2)The analysis of complexions showed that in comparison with the balanced group,lusterless complexion(79.08％)and pale lip(42.15％)were frequently seen in the yang deficiency group,with statistically significant differences(P＜0.01).(3)The yang deficiency group had higher L value of tongue color,L value of tongue coating color,L value of complexions,and L and b values of lip color than the balanced group,and the differences were all statistically significant(P＜0.05),indicating that the tongue color,complexions,and lip color of the yang deficiency group were all pale.Conclusion The objective data and image analysis of tongue manifestations and complexions can accurately identify the population of yang deficiency constitution from college students,and the results will provide approaches and references for the identification of other TCM constitutions from the population.
