AIM:To analyze the influencing factors of postoperative malignant glaucoma(MG)in patients with primary angle-closure glaucoma(PACG)using logistic regression and decision tree models.METHODS:A retrospective study was conducted on PACG patients who underwent surgery at Eye Hospital of Handan City from March 2020 to March 2025. Patients were divided into two groups: the MG group, who developed MG within 6 mo postoperatively, and the non-MG group. Data were collected from the electronic medical record system. Univariate analysis was performed, followed by multivariate logistic regression to identify independent risk factors. A classification and regression tree model was constructed to visualize the hierarchical relationships among predictors. The predictive performance of the two models was evaluated and compared using receiver operating characteristic(ROC)curve analysis.RESULTS:Totally 182 cases(182 eyes)with PACG were enrolled in this study, including 91 cases(91 eyes)in the MG group and 91 cases(91 eyes)in the non-MG group. In the MG group, there were 53 males and 38 females; 69 cases were aged ≥60 y and 22 cases were aged <60 y. In the non-MG group, there were 47 males and 44 females; 33 cases were aged ≥60 y and 58 cases were aged <60 y. The non-MG group comprised 91 patients, including 47 males and 44 females. Among them, 33 cases were aged ≥60 y, and 58 cases were aged<60 y. The MG group had significantly higher proportions of patients aged ≥60 y, diabetes, moderate-stage PACG, persistent high intraocular pressure(IOP), complete anterior chamber angle closure, lens thickness <4.5 mm, axial length <22 mm, and severe postoperative inflammation compared to the non-MG group(all P<0.01). Multivariate Logistic regression identified the following as independent influencing factors for postoperative MG: age [OR (95%CI)=2.136(1.401-3.255)], PACG stage [OR (95%CI)=2.996(2.044-4.391)], IOP [OR (95%CI)=3.527(1.604-7.755)],anterior chamber angle [OR (95%CI)=4.826(2.498-9.324)], axial length [OR (95%CI)=5.125(1.265-20.771)], and severe postoperative inflammation [OR (95%CI)=2.338(1.478-3.699)](all P<0.05). The decision tree model selected six explanatory variables: age, PACG stage, IOP, anterior chamber angle status, axial length, and severe postoperative inflammation. Axial length was the primary splitting factor at the root node. The areas under the ROC curve(AUC)for the logistic regression and decision tree models were 0.913(0.863-0.950)and 0.921(0.872-0.956), respectively, with no significant difference between them(Z=0.561, P=0.575).CONCLUSION:Both the logistic regression and decision tree models effectively identify key influencing factors for postoperative MG in PACG patients, including age, PACG stage, IOP, anterior chamber angle status, axial length, and severe postoperative inflammation. The decision tree model offers an intuitive, visual representation of risk stratification, facilitating clinical decision-making. Both models are applicable for clinical risk assessment.

Post-stroke sleep disorders(PSSDs)are defined as a clinical syndrome that occurs for the first time after the onset of stroke and meets the diagnostic criteria.The incidence of PSSDs has a great impact on the rehabilitation of emotion,cognition and motor function of stroke patients.The types of PSSDs exhibit multiplicity,primarily leading to alterations in the sleep architecture of stroke patients.The mechanism of occurrence and development of PSSDs are related to the neurotransmitter agents,neuroendocrine hormones and cytokines.A comprehensive insight of PSSDs will contribute to timely identification and developing appropriate treatment to ensure recovery of patients.This article summarizes the change of sleep structure,the correlation between sleep disorders and brain lesions,epidemiological characteristics and signal molecular biological characterization of PSSDs,in order to provide reference for further research and clinical treatment.

Tetanus consists of neonatal tetanus and non-neonatal tetanus. Non-neonatal tetanus remains a serious public health problem, although neonatal tetanus has been eliminated in China since 2012. Non-neonatal tetanus is a potential fatal disease. In the absence of medical intervention, the mortality rate of severe cases is almost 100%. Even with vigorous treatment, the mortality rate remains 30%-50% globally. These specifications aim to regulate non-neonatal tetanus diagnosis and treatment in China, in order to improve medical quality and safety. These specifications introduce the etiology, epidemiology, pathogenesis, clinical manifestations and laboratory tests, diagnosis, differential diagnosis, grading and treatment of non-neonatal tetanus.

Objective To study the effect of Xuebijing injection on the change of intestinal tract mucosa barriers and the expression of macrophage antihody in rats with sepsis. Method Totally 150 Wistar rats were ran-domly divided into three groups: sham group, sepsis group, and Xuebijing group. Sepsis models were estabhshed in rats by cecal ligation and puncture. The success standards of sepsis included fever, the increase of respiration rate,increased heart rate and change in leukocyte count. At 12 hours before operation, and after operation the rats in the Xuebijing group were injected with 4 mL/kg Xuebijing (once every 12 hours for 3 days), and the rats in the others two groups were injected with the same volume of saline, the image analytical system were used to detect the pathological change of intestinal tract mucosa harriers and the expression of macrophage antibody in three groups. All the data were analyzed by rank-sum test and variance analysis(F test). Results Almost all the mucous mem-brahe of small intestine in sham groups were normal. The mucous membrane lesions of small intestine developed in sepsis and Xuebijing groups after 12,24,48,72 hours, and the lesion was severer in sepsis group than that in the Xuebijing group (H=19.732, P<0.01). There were no significant differences on the expression of macrophage antibody in mucous membrane of small intestine between three groups at 3 hours. But at 12, 24, 48 and 72 hours, the expression of macmphage antibody of sepsis and Xnebijing groups increased with time (F=560.13, P< 0.05). Conclusions At the early period of sepsis, intestinal tract mucosa barriers develops varying degrees of damage, and Xnebijing can partly protect intestinal tract mucosa barriers.
