ObjectiveTo investigate the feasibility， safety， and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt （SA-TIPS） in the treatment of portal hypertension comorbid with complex portal vein thrombosis， including cavernous transformation of the portal vein （CTPV）. MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital， Capital Medical University， from November 2023 to January 2025， including general status， technical data of the surgical process （surgical success rate， puncture times， time of operation， the number of stents used， and the length of shunt）， perioperative complications， and surgical recovery. The change in portal pressure gradient （PPG） after shunt was compared， and the rate of reaching the standard for PPG reduction was calculated， as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients， 34 （94.4%） underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% （6/36）， including 3 cases of thoraco-abdominal hemorrhage， 2 cases of intraoperative arrhythmia， and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS （t=19.85， P<0.01）， and the patients achieving a ≥50% reduction in PPG accounted for 76.5% （26/34）. Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate， a favorable safety profile， and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis （including CTPV）， and therefore， it holds promise for clinical application.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

ObjectiveTo develop a machine learning (ML)-based prediction model for neurological rehabilitation outcomes of stroke patients. MethodsA total of 420 stroke patients admitted to the Fuzhou First People's Hospital from October, 2022 to October, 2024 were enrolled as the training set. According to the modified Rankin Scale (mRS) scores three months after discharge, the patients were divided into prognosis group (n = 289) and poor prognosis group (n = 131). An additional 180 stroke patients hospitalized in the same hospital from November, 2024 to April, 2025 were selected as the validation set. Univariate analysis, least absolute shrinkage and selection operator regression, and multivariate logistic regression were performed to identify independent influencing factors for the prognosis of neurological function recovery. Using the screened independent influencing factors as feature variables, six ML models were established, including logistic regression, linear discriminant analysis, naive Bayes, support vector machine, random forest and extreme gradient boosting (XGBoost). The area under the receiver operating characteristic curve (AUC), confusion matrix indicators (accuracy, precision, recall and F1-score), calibration curve and decision curve analysis were adopted to evaluate the predictive efficacy, calibration degree and clinical net benefit of each model, with external validation conducted in the validation set. The SHapley Additive exPlanations framework was used to interpret the optimal model, and bar charts were applied to visualize the feature importance of the best model. ResultsAge, National Institutes of Health Stroke Scale (NIHSS) score, collateral circulation grading, fasting plasma glucose (FPG), lymphocyte percentage (LYMPH%), and homocysteine (Hcy) were independent risk factors for poor neurological rehabilitation prognosis (P < 0.05). For the XGBoost model, the AUC of the training and validation sets were 0.963 (95%CI 0.947 to 0.979) and 0.825 (95%CI 0.764 to 0.885), respectively, while the accuracy was 88.81% and 77.22%, the precision was 92.86% and 68.42%, the recall was 69.47% and 47.27%, and the F1-score was 79.48% and 55.91%, optimal in both calibration and clinical net benefit. The feature importance ranking for the XGBoost model from high to low was NIHSS score, age, collateral circulation grading, FPG, Hcy and LYMPH%. ConclusionThe interpretable XGBoost ML model exhibits excellent predictive efficacy and favorable clinical applicability in predicting neurological rehabilitation outcomes for stroke patients.

OBJECTIVE: To investigate the safety and prognostic factors influencing the treatment of upper urinary tract urothelial carcinoma (UTUC) combined with bladder cancer (BCa) by laparoscopic simultaneous radical cystectomy and nephroureterectomy (RCNU). METHODS: The clinical data of patients admitted to Peking University Third Hospital for laparoscopic RCNU surgery from January 2009 to September 2023 were analyzed retrospectively. Based on the same gender, age (±5 years), history of uroepithelial tumors, underlying diseases, T-stage, N-stage, M-stage, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, and body mass index (BMI) (±5), 34 patients with RCNU were matched 1 ∶1 with patients with bladder cancer who underwent laparoscopic radical cystectomy (RC) alone. Kaplan-Meier survival analysis was used to calculate patient survival, and Cox proportional regression risk model was used to analyze clinical factors affecting prognosis. RESULTS: Of the 68 patients enrolled, the follow-up rate was 100% with a median follow-up time of 27.0 (11.7, 60.2) months. Comparison of intraoperative conditions (including operation time, estimated intraoperative bleeding, intra-operative blood transfusion, etc.) between the two groups of patients showed no significant difference (P>0.05). Comparison of preoperative creatinine and postoperative creatinine between the two groups of patients showed significant differences (P < 0.05). The perioperative Clavien grade Ⅲ-Ⅳ complication rates were 2.9% (1/34) in the RC group and 5.9% (2/34) in the RCNU group. There was no significant difference in terms of perioperative complications between the two groups. Overall survival was significantly lower in the patients receiving RCNU compared with the matched group receiving RC alone (P < 0.05). Cox regression analysis suggested that two factors, high N stage and high postoperative creatinine, were independent risk factors affecting the prognosis of patients in the 2 groups (P < 0.05). CONCLUSION The overall survival prognosis of patients undergoing RCNU surgery was worse compared with laparoscopic RC surgery alone during the same period. There was no clinically significant difference between the two groups in terms of operation time, intraoperative bleeding, and perioperative complications, and there were clinically significant differences in preoperative renal function and post-operative renal function.

Magnetic stimulation has made significant strides in the treatment of psychiatric disorders. Nonetheless, current magnetic stimulation techniques lack the precision to accurately modulate specific nuclei and cannot realize deep brain magnetic stimulation. To address this, we utilized superparamagnetic iron oxide nanoparticles as mediators to achieve precise targeting and penetration. We investigated the effects of magnetic fields with varying frequencies on neuronal activity and compared the activation effects on neurons using a 10-Hz precise magneto-stimulation system (pMSS) with repetitive transcranial magnetic stimulation in mice. Oxytocin levels, dendritic morphology and density, and mouse behavior were measured before and after pMSS intervention. Our findings suggest that pMSS can activate oxytocinergic neurons, leading to upregulation of oxytocin secretion and neurite outgrowth. As a result, sociability was rapidly improved after a one-week pMSS treatment regimen. These results demonstrate a promising magneto-stimulation method for regulating neuronal activity in deep brain nuclei and provide a promising therapeutic approach for autism spectrum disorder.

Objective:ANXA2 plays a crucial role in cancer metastasis, but its mechanism is not yet fully understood. Therefore, it is necessary to establish an ANXA2 gene knockout mouse model to provide an effective tool for subsequent studies on ANXA2-related mechanisms.Methods:A gene knockout mouse model was constructed using CRISPR/Cas9 technology. The model was validated through tissue DNA extraction followed by polymerase chain reaction (PCR), sequencing, and western blot to confirm ANXA2 genotype and protein expression. The successfully constructed models were divided into a model group and a wild-type (WT) group for the creation of a mouse tail vein injection Lewis lung carcinoma (LLC) metastasis model. Metastatic foci formation was monitored using in vivo imaging technology, and the survival rates of the two groups were compared. Results:An sgRNA sequence targeting the first exon of ANXA2 was designed, and 16 founder mice were obtained through microinjection. Through consanguineous hybridization, 30 homozygous offspring were ultimately acquired. After establishing the strains of the mouse model, mice were divided into the ANXA2 knockout group and the WT group, with 8 mice in each group. An LLC lung metastasis model was established in both groups. Compared with the WT group, the number of metastatic foci was significantly increased in the ANXA2 knockout group (7 vs. 1), and the fluorescence intensity was stronger in the WT group than in the knockout group ( P=0.002). Using the GEPIA2 database to analyze ANXA2 gene expression in tumor tissues and normal tissues of lung cancer patients, it was found that ANXA2 expression levels were significantly higher in lung cancer tumor tissues compared to normal tissues ( P＜0.05). The database included data from 478 lung cancer patients, and patients were stratified into high-expression and low-expression groups based on ANXA2 levels. Compared to the low-expression group, patients in the high-expression group exhibited significantly shorter disease-free survival and overall survival ( P＜0.05, respectively). The survival time of mice in the ANXA2 knockout group (median survival time, 43 days) was significantly longer compared to the WT group (median survival time, 26 days; P=0.017). Additionally, ANXA2 expression is significantly associated with the prognosis of lung cancer patients ( P=6.4e-14). Conclusions:ANXA2 is closely associated with cancer metastasis and holds potential as a new target for metastasis treatment. Further in-depth research will greatly facilitate the transition of ANXA2 from basic research to clinical application.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Objective:To investigate the impact of limonin(LIM)on the necrotic apoptosis of myocardial cells in rats with myocardial infarction(MI)by regulating the receptor-interacting protein 1(RIP1)/receptor-interacting protein 3(RIP3)/mixed-lineage kinase domain-like protein(MLKL)signaling pathway.Methods:A total of 60 Sprague-Dawley rats were randomly divided into sham-operation group(Sham group),MI model group(Model group),low-dose LIM group(LIM-L group,25 mg/kg LIM),high-dose LIM group(LIM-H group,50 mg/kg LIM),and high-dose LIM+RIP1 inhibitor Nec-1 group(LIM-H+Nec-1 group,50 mg/kg LIM+0.6 mg/kg Nec-1),with 12 rats in each group.A rat model of MI was established by ligation of the coronary artery.The changes of cardiac func-tion were examined for each group;HE staining was used to observe the pathological changes of myocardial tissue;the 2,3,5-triphen-yltetrazolium chloride-Evans blue method was used to measure myocardial infarct area;the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method was used to observe the necrotic apoptosis of myocardial cells;quantitative real-time PCR and Western blot were used to measure the expression levels of mRNAs and proteins associated with the RIP1/RIP3/MLKL signaling pathway and the expression of apoptosis-related proteins.Results:Compared with the Sham group,the Model group had significant re-ductions in left ventricular ejection fraction,left ventricular systolic pressure,and the expression level of B-cell lymphoma-2(Bcl-2)in myocardial tissue(all P<0.001)and significant increases in left ventricular end-systolic volume,left ventricular end-diastolic pres-sure,left ventricular end-diastolic volume,myocardial infarct area,cell apoptosis rate,the mRNA and protein expression levels of RIP1,RIP3,and MLKL in myocardial tissue,and the protein expression levels of Bcl-2 associated X protein and cysteinyl aspartate-specific proteinase 3 in myocardial tissue(all P<0.001),as well as swelling and disordered arrangement of myocardial cells with ne-crosis and massive inflammatory cell infiltration on HE pathological sections.Compared with the Model group,the LIM-H group showed reverse changes in the above indicators(RIP1 mRNA:P=0.002,RIP3 mRNA:P=0.008,and the other indexes P were all<0.001),with alleviations of myocardial histopathological injury and inflammatory cell infiltration.Nec-1 promoted the effect of LIM in alleviating the necrotic apoptosis of myocardial cells in MI rats.Conclusion:LIM may alleviate the necrotic apoptosis of myocardial cells in MI rats by downregulating the RIP1/RIP3/MLKL signaling pathway.

AIM: To analyze the recovery of stereopsis and its influencing factors in children with intermittent exotropia(IXT)after binocular vision training.METHODS: A total of 166 cases of IXT children who were treated in our hospital from October 2021 to October 2023(2 cases lost their follow-up, and 164 cases were finally included)were included as the research object, taking 36 cases with no stereopsis after binocular vision training in eye position correction surgery as no stereopsis group, and other 128 cases as stereopsis group. All the children underwent eye position correction surgery under general anesthesia, and all received binocular vision training for 6 mo after surgery. The recovery of stereoscopic vision of IXT children after binocular vision training was counted, and the influencing factors of stereoscopic vision recovery of IXT children after binocular vision training were analyzed by single factor and multi-factor Logistic regression analysis.RESULTS: The incidence of postoperative no stereopsis was 22.0%. The proportion of children with an age ≥9 years old, course of disease ≥1 a and anisometropia in the group without stereoscopic vision after operation was larger than the group with stereoscopic vision(all P<0.05). Multivariate Logistic regression analysis showed that the course of disease ≥1 a, age ≥9 years old and anisometropia were independent influencing factors for the recovery of stereoscopic vision in IXT children after binocular vision training(OR=1.470, 1.626, 1.539, all P<0.05).CONCLUSION: Age ≥9 years old, course of disease ≥1 a, and anisometropia are the independent influencing factors of stereopsis recovery of IXT children after binocular vision training. Therefore, targeted intervention measures can be given to high-risk children to improve the stereopsis recovery of IXT children after binocular vision training.

Objective To study the predictive value of the Prognostic Assessment Scale for Patients with Spontaneous Intracerebral Hemorrhage(ICH-LR2S2)and the Prehospital Risk Assessment Scale for Prehospital Deterioration Risk Assessment Scale(ICH-APS)for the development of stroke-associated pneu-monia(SAP)in patients with spontaneous intracerebral hemorrhage.Methods A total of 349 patients with spontaneous intracerebral hemorrhage who were hospitalized for the first time in this hospital from July 2023 to July 2024 were selected as the research subjects.The general demographic data and medical documentations of the patients were collected,and ICH-LR2S2 score and ICH-APS score were carried out within 48 hours after admission.According to whether pneumonia occurred within 7 days after admission,the patients were divided into the SAP group and the non-SAP group,and the diagnostic efficiency of the ICH-LR2S2 score and ICH-APS score for SAP in patients with spontaneous intracerebral hemorrhage was evaluated.Results Among the 349 patients with spontaneous intracerebral hemorrhage,98 patients(28.08％)had pneumonia.The results of multivariate logistic regression analysis showed that age,history of chronic obstructive pulmonary disease(COPD),nasogastric tube,tracheal intubation,National Institutes of Health Stroke Scale(NIHSS)score,Glasgow Coma Scale(GCS)score,C-reactive protein,fasting blood glucose,dysphagia,ICH-LR2S2 score,ICH-APS-A score,and ICH-APS-B score were independent influencing factors for SAP in patients with spontane-ous intracerebral hemorrhage(P＜0.05).The results of the receiver operating characteristic(ROC)curve showed that the ICH-LR2S2 score had the highest diagnostic efficiency for SAP in patients with spontaneous intracerebral hemorrhage,with an area under the curve(AUC)of 0.837,a sensitivity of 0.827,a specificity of 0.783,and a Youden index of 0.610.Conclusion ICH-LR2S2 score has a high predictive value for the occur-rence of SAP in patients with spontaneous intracerebral hemorrhage.
