ObjectiveTo investigate the clinical characteristics of a child with Klippel-Trenaunay syndrome （KTS） complicated by lower gastrointestinal bleeding， for better understanding of this rare condition. MethodsA retrospective analysis was conducted on the clinical data of a pediatric KTS case with lower gastrointestinal bleeding admitted to the Department of Gastroenterology of the Affiliated Women and Children's Medical Center of Guangzhou Medical University in October 2024. Using "Klippel-Trenaunay Syndrome" "KTS" "Gastrointestinal Bleeding" as keywords， we searched for relevant literature in the Wanfang Chinese Database and PubMed database up to March 2025 in our analysis. ResultsThe 8‑year‑old boy was admitted with a 4‑year history of hematochezia that had worsened over the previous two weeks. He had been previously diagnosed with KTS in outpatient consultation for lower limb asymmetry. Gastrointestinal endoscopy revealed diffuse， tortuous， bluish‑purple vessels in the mucosa from the sigmoid colon to the distal rectum. Oral polyethylene glycol and thalidomide significantly improved his hematochezia during follow‑up. ConclusionKTS often involves multiple systems in children， requiring multidisciplinary collaboration. Comprehensive diagnostic procedures such as gastrointestinal endoscopy are essential for formulating individualized treatment plans. Thalidomide may play an active role in managing vascular malformations in the intestine， offering a promising therapeutic approach.

Epileptic seizure classification serves as an essential tool for evaluating seizures in clinical practice. In 2025, the International League Against Epilepsy updated the classification framework for epileptic seizures. An interpretation of the key updates is provided, with detailed content presented below: "onset" is removed from the names of the main seizure classes; consciousness is used as a classifier instead of awareness; the dichotomy of motor and non-motor is replaced by observable vs nonobservable manifestations; epileptic negative myocionus is recognized as a seizure type, to clarify the key updates to facilitate better application of the consensus in clinical practice.

Objective:To investigate the treatment approaches and outcomes of early hepatic artery thrombosis (E-HAT) in adult recipients following orthotopic liver transplantation (OLT).Methods:A retrospective analysis was conducted on clinical data of E-HAT cases after adult OLT at the First Affiliated Hospital of Xi'an Jiaotong University from January 2010 to June 2022. Clinical characteristics, treatment methods, therapeutic outcomes, long-term survival of recipients and grafts, and the incidence of long-term complications were summarized. The Kaplan-Meier method was utilized to calculate recipient survival rates.Results:Among 1 016 OLT recipients, 22 cases (2.2%) developed postoperative E-HAT. There were 19 males and 3 females, with a age of 44.81±9.98 years. E-HAT was diagnosed via angiography at a median of 3.5 (1.0, 7.0) days post-OLT. Twenty recipients underwent vascular intervention therapy, achieving clinical success in 14 cases (70.0%) with a mean thrombolysis duration of 5.1±3.2 days. Twelve cases (60.0%) experienced complications, including abdominal bleeding (10 cases), gastrointestinal bleeding (1 case), catheter-related infection (1 case), subcutaneous bleeding (1 case), and hepatic artery dissection (1 case). Five recipients underwent hepatic artery re-anastomosis, including two initial cases and three following failed interventional therapy. Surgery was performed at a median of 5.0 (1.0, 15.3) days post OLT, with 4 successful cases. Through combined interventional and surgical treatment, 81.8% (18/22) of grafts were salvaged. However, the success rate was significantly lower in cases with marked transaminase (AST, ALT) and total bilirubin elevation (16/18 vs 2/4). Nineteen E-HAT survivors were followed for a median of 22 (5, 52) months. During follow-up, 2 cases experienced thrombus recurrence, and 12 cases developed biliary complications, including ischemic biliary stenosis (11 cases), extensive liver necrosis (1 case), localized liver abscess (1 case), and biliary anastomotic stenosis (1 case). Seven recipients died due to graft failure. The 1-year, 3-year and 5-year cumulative survival rates were 67.2%, 60.5% and 34.5%, respectively.Conclusions:Combined interventional and surgical treatment demonstrates a high success rate for managing E-HAT, particularly when addressed before significant graft damage. Ischemic biliary stenosis remains the most common long-term complication.

It is believed that wind pathogen is one of the core pathogenic factors of small cell lung cancer （SCLC）. The nature and pathogenic characteristics of wind pathogen are closely related to the occurrence and metastasis of SCLC. Mainly manifested as deficiency of both qi and yin， healthy qi deficiency of SCLC makes it susceptible to invasion of external wind. Simultaneously， there are internal wind pathogenesis such as yin deficiency causing wind， blood deficiency causing wind， phlegm， stasis and toxin causing wind， liver yang transforming into wind. The internal and external winds together lead to the disease. Therefore， it is proposed to treat SCLC from wind theory， that is， boosting qi and nourishing yin to extinguish wind with taizishen （Radix Pseudostellariae）， wuweizi （Fructus Schisandrae Chinensis） and others； resolving phlegm and moving stasis to dispel wind with wind-dispelling and phlegm-resolving medicinals such as jiangcan （Bombyx Batryticatus）， muhudie （Semen Oroxyli）， fangfeng （Radix Saposhnikoviae）， tianma （Rhizoma Gastrodiae）， quanxie （Scorpio） and blood-invigorating and wind-dispelling medi-cinals such as danggui （Radix Angelicae Sinensis）， chuanxiong （Rhizoma Chuanxiong） and danshen （Radix et Rhizoma Salviae Miltiorrhizae）； attacking toxin and dissipating masses to dispel wind with shuizhi （Hirudo）， dilong （Pheretima）， fengfang （Nidus Vespae）， quanxie， baihuashe （Agkistrodon）， jiuxiangchong （Aspongopus） and other drastic medicinals； calming liver and extinguishing wind to prevent brain metastasis of SCLC with Tianma Gouteng Beverage （天麻钩藤饮） modification.

Objective To analyze the predictive value of cone beam computed tomography(CBCT)in styloid process syndrome(SPS)via logistic regression combined with receiver operating characteristic(ROC)curve.Methods A retrospective analysis was conducted on imaging data of 186 patients who underwent styloid CBCT.Among them,65 patients were clinically diagnosed with SPS(patient group),while 121 constituted the healthy controls(control group).The styloid length,inclination angle,and anteversion angle were measured,respectively.Logistic regression analysis was employed,and ROC curves were plotted to calculate sensitivity,specificity,and Youden index,the diagnostic cut-off values for SPS was obtained.Results In the control group,the styloid length was(29.66±7.22)mm,inclination angle was(22.34±3.05)°,and anteversion angle was(31.01±4.13)°.In the patient group,the styloid length was(40.30±8.65)mm,inclination angle was(21.86±3.74)°,and anteversion angle was(35.88±6.37)°.Logistic regression analysis revealed that styloid length and anteversion angle were risk factors for diagnosing SPS(P＜0.05),while inclination angle was not a risk factor for diagno-sing SPS(P＞0.05).ROC curve analysis demonstrated that diagnosing SPS,the area under the curve(AUC),sensitivity,specificity,and optimal cut-off value for styloid length were 0.868,92.3％,69.7％,and 31.23 mm,respectively;and for anteversion angle were 0.765,63.1％,89.3％,and 35.15°,respectively.Conclusion CBCT measurements of styloid length,inclination angle,and antever-sion angle suggest that a styloid length exceeding 31.23 mm and an styloid anteversion angle greater than 35.15° may indicate a higher likelihood of SPS.CBCT is a convenient,cost-effective,and safe diagnostic tool with positive clinical implications.

Tumor immune checkpoint inhibitors (ICIs) present a dual nature, offering therapeutic benefits alongside possible toxic side effects. Despite their significant clinical advantages, immune-related adverse events (irAEs) are major concern. In particular, the multi-organ irAEs (MO-irAEs) caused by ICIs present complex clinical manifestations, affecting a high proportion of critically ill patients. There is a lack of clinical awareness and attention towards these adverse events, making management relatively difficult, thus potentially threatening the life of patients. Reasonable application of hormones and immune modulators, along with symptomatic and supportive treatment, as well as careful monitoring and long-term follow-up are crucial measures to control MO-irAEs. Clinical characteristics, peripheral blood indicators, and genetic predisposition can serve as predictive markers for MO-irAEs occurrence and progression to some extent. A comprehensive understanding of clinical features, intervention measures, prognosis, potential molecular mechanisms and predictive factors of MO-irAEs can help to effectively control MO-irAEs, ultimately improving patient outcomes.

Objective:To discover the epidemiological characteristics and clinical manifestations of Nontyphoidal Salmonella(NTS) infection in children suffering from diarrhea in Guangzhou, and to provide references for the prevention and treatment of salmonella infection. Methods:A total of 570 diarrhea children and 296 non-diarrhea controls were collected with stratified sampling from three districts of Guangzhou Women and Children′s Medical Center from January 2019 to December 2019. Through bacterial culture, corresponding colonies were selected and Salmonella diagnostic serum was applied for preliminary serum diagnosis, and then systemic biochemical method was adopted for diagnosis. A structured questionnaire was conducted to record the demographic information and clinical symptoms from each subject. Results:The detection rate of NTS was 6.67% (38/570 cases, 95% CI: 4.90%-9.02%) in children with diarrhea, and 1.01% (3/296 cases, 95% CI: 0.34%-2.93%) in children without diarrhea. There were statistically differences in NTS detection rate between children with diarrhea and the control ( χ2=13.805, P<0.05, OR=6.976, 95% CI: 2.135-22.796). There were no significant differences in NTS detection rate between male and female children with diarrhea ( χ2=0.395, P>0.05, OR=1.254, 95% CI: 0.619-2.541). The detection rate of NTS was 5.30% (22/416 cases, 95% CI: 3.52%-7.88%) in children younger than 2 years old, and was 10.40% (16/154 cases, 95% CI: 6.50%-15.21%) in children over 2 years old. There were statistically differences ( χ2=4.700, P<0.05, OR=2.076, 95% CI: 1.060-4.068) between the younger and the older groups.The detection rate of NTS was 5.40% (25/460 cases, 95% CI: 3.70%-7.89%) for children with diarrhea in outpatient department and 11.80% (13/110 cases, 95% CI: 7.04 %-19.18%) for children with diarrhea in inpatient department, with statistically significant differences ( χ2=5.813, P<0.05, OR=2.332, 95% CI: 1.152-4.721). The detection rate of NTS diarrhea in children was 4.60% (10/217 cases, 95% CI: 2.52%-8.28%) in spring, 8.50% (12/141 cases, 95% CI: 4.93%-14.29%) in summer, 9.60% (15/144 cases, 95% CI: 6.41%-16.48%) in autumn and 1.50% (1/168 cases, 95% CI: 0.11%-3.30%) in winter, respectively, with statistically differences among the four seasons( χ2=9.404, P<0.05). There were significant differences in most common clinical symptoms of fever, vomiting, abdominal pain, bloody stool and pasty stool between NTS positive and negative children(all P<0.05). Salmonella enteritis is the main type, and Salmonella typhimurium is the second type. Conclusions:NTS is one of the most important bacterial pathogens and leads to diarrhea in children in Guangzhou city, without differences in gender.Children over 2 years old are more likely to suffer from NTS infection.High incidence is in autumn.The most common clinical symptoms include fever, vomiting, abdominal pain, bloody stool and pasty stool. Salmonella enteritis is the main type, and Salmonella typhimurium is the second type.Laboratory tests can provide references for the diagnosis and treatment of NTS-related diarrhea.

Objective To investigate the inhibitory effect of apigenin-7-o-glucoside (AGL) on the viability of Huh7 cells and tumor growth in Huh7-xenograft tumor nude mice. Methods CCK-8 was used to detect the proliferation inhibitory effect and the half inhibitory concentration of AGL on Huh7 cells. The mitochondrial membrane potential measurement was used to analyze the early apoptosis of Huh7 cells after AGL treatment. Flow cytometry was used to analyze the effect of AGL on Huh7 cell apoptosis, and Western blot was used to explore the expression level of the proteins associated with apoptosis and inflammation, as well as the possible related mechanism. In Huh7-xenograft tumor nude mice, vernier caliper was used to measure tumor volume to analyze the effect of AGL on tumor growth rate. HE staining was used to observe the pathological state of mouse organs, and the inflammation-related factors in serum were detected with ELISA. Results After Huh7 cells were treated with AGL, the mitochondrial membrane potential reduced, the content of ROS increased and the apoptosis rate was increased to 25.23% by 50 μmol/L AGL treatment; while the expression levels of Bax, Bad, Cleaved Caspase-3 and Cleaved Caspase-9 increased, and the expression levels of Bcl2 and Bcl-x^L decreased, the phosphorylation level of NF-κB, IKKα/β and IκBα decreased; the tumor growth rate decreased, the serum IL-6 and TNF-α levels significantly decreased, while the IL-2 and IL-10 levels increased. Conclusion AGL could promote the apoptosis of Huh7 cells and relieve the tumor development in Huh7-xenograft tumor nude mice, which may be related to the NF-κB pathway.
