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.

Objective:To explore the influencing factors of olfactory impairment in patients with obstructive sleep apnea(OSA) and establish a nomogram prediction model. Methods:A total of 100 OSA patients were enrolled. Snap&Sniff olfactory test was used to evaluate the olfactory identification function and olfactory threshold of the patients. According to the scoring criteria, either olfactory identification scores below 14 points or olfactory threshold scores below 3 points was defined as olfactory impairment. Multivariate logistic regression analysis was used to explore the influencing factors of olfactory impairment in OSA. The nomogram model was constructed by using the R 4.4.2 software package. ROC curve, calibration curve and decision curve were used to evaluate the predictive efficacy, consistency and clinical utility of the model. Results:A total of 55 of 100 OSA patients had olfactory impairment. The results of multivariate logistic regression analysis showed that age, ESS score, MoCA score, and apnea-hypopnea index(AHI) were the influencing factors of olfactory impairment in OSA. Based on the above parameters, a nomogram model was established. The ROC curve analysis showed that the AUC was 0.897(95%CI 0.834-0.961), indicating that the model had good predictive ability. The calibration curve showed that the predicted probability of the model fits the actual probability well. Decision curve analysis showed that when the threshold probability was in the range of 0-0.9, the model had a high clinical net benefit rate. Conclusion:Age, ESS score, MoCA score and AHI are the influencing factors of olfactory impairment in patients with OSA. The nomogram model constructed based on the above factors has good predictive value, which is conducive to the clinical multi-angle understanding of OSA and the formulation of scientific prevention and treatment measures.

Objective:To investigate the impact of different ventilation modalities during initial resuscitation on short-term outcomes in adult patients with in-hospital cardiac arrest (IHCA).Methods:This retrospective study included adult patients (age ≥18 years) admitted to the emergency resuscitation or observation units of our hospital from September 2019 to December 2021. Demographic data, comorbidities, and short-term outcomes of IHCA patients who underwent airway management during resuscitation were recorded. Participants were stratified into non-advanced airway and advanced airway groups based on ventilation modality. The primary outcome was defined as sustained return of spontaneous circulation (ROSC) ≥20 min, and secondary outcomes included survival to discharge and favorable neurological status at discharge. Logistic regression analyses were performed to assess the impact of different ventilation modalities on short-term outcomes among adult IHCA patients. and developed a prediction model of ROSC for adult IHCA patients, and its predictive performance was evaluated by the area under the curve (AUC) of the receiver operating characteristic.Results:Among 285 IHCA patients (non-advanced airway: n=75; advanced airway: n=210), 127 achieved ROSC ≥20 min, 51 survived to discharge, and 35 had favorable neurological outcomes. Logistic regression identified ventilation modality, epinephrine dose, and arrest location as independent predictors of ROSC in adult IHCA patients. Advanced airway management demonstrated significantly higher ROSC rates compared to non-advanced interventions ( OR=3.698, 95% CI:1.844-7.419, P<0.001). However, no significant associations were observed between ventilation modalities and survival to discharge ( OR=1.097, 95% CI:0.506-2.376, P=0.815) or favorable neurological outcomes at discharge ( OR=0.548, 95% CI:0.224-1.339, P=0.187). Ventilation modality, epinephrine dose, and arrest location were incorporated as predictors in a multivariable logistic regression model to develop a ROSC prediction model for adult IHCA patients. The discriminative ability of model was evaluated through receiver operating characteristic (ROC) curve analysis, yielding an AUC of 0.735 (95% CI:0.678-0.793). Subgroup analyses demonstrated that early advanced airway management significantly enhanced ROSC rates in noncardiac etiology cases, whereas no such benefit was observed in cardiac etiology cases, while this intervention correlated with decreased survival to discharge rates and deteriorated neurological outcomes among survivors. Conclusions:Advanced airway management demonstrated improved ROSC rates in adult IHCA cases, while showing no significant improvement in survival rates or favorable neurological outcomes at discharge. Ventilation modality, epinephrine dose, and arrest location are independent predictors of ROSC. A model integrating these factors exhibits moderate predictive utility for IHCA outcomes.

ObjectiveTo investigate the protective effect of salidroside against nonalcoholic fatty liver disease (NAFLD) and its mechanism of action. MethodsA total of 24 male KM mice were randomly divided into normal group, HFD group, HFD+blank control group, and HFD+salidroside group, with 6 mice in each group. The mice in the normal group were given normal diet, and those in the other groups were given high-fat diet. After 14 weeks of modeling, the mice were given salidroside 100 mg/kg/day by gavage, and related samples were collected at the end of week 22. Enzyme-linked immunosorbent assay was used to measure the serum levels of related biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C); HE staining and NAFLD activity score (NAS) were used to observe the liver histopathology of mice; Western blot was used to measure the changes in the expression of NAMPT, Sirt1, AMPKα, and SREBP1 in liver tissue. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group, the HFD group had obvious steatosis and extensive large lipid droplets in liver tissue, with significant increases in NAS score (P<0.01) and the content of AST, ALT, TG, TC, and LDL-C in peripheral blood (all P<0.05) and a significant reduction in the content of HDL-C (P<0.05), as well as significant reductions in the expression levels of NAMPT, AMPKα, and Sirt1 in liver tissue (all P<0.05) and a significant increase in the expression level of SERBP1 (P<0.01). Compared with the HFD group and the HFD+blank control group, the HFD+salidroside group had reductions in the distribution of vacuolar lipid droplets and intralobular inflammation in liver tissue, alleviation of the ballooning degeneration of hepatocytes, significant reductions in NAS score (P<0.01) and the content of AST, ALT, TG, and LDL-C in peripheral blood (all P<0.05), and a significant increase in the content of HDL-C (P<0.05), as well as significant increases in the expression levels of NAMPT, AMPKα, and Sirt1 in liver tissue (all P<0.05) and a significant reduction in the expression level of SERBP1 (P<0.01). ConclusionSalidroside can significantly improve the pathological state of mice with NAFLD induced by high-fat diet and exert a protective effect against NAFLD by increasing the expression of NAMPT, Sirt1, and AMPKα and reducing the expression of SERBP1.

Objective:To explore the advantages of the modified right renal artery dissection in the laparoscopic resection of right renal carcinoma combined with venous tumor thrombus.Methods:From January 2016 to June 2016, a retrospective analysis of the three-dimensional CT images of renal blood vessels in 70 patients with full abdominal CT plain scan plus enhanced scan from Shandong Provincial Hospital Affiliated to Shandong First Medical University was performed. On the sagittal plane of the right margin of the aorta, the right renal artery was detected to locate above the left renal vein in 14 cases (20.0%), posterior in 33 cases(47.1%), and below in 23 cases(32.9%). In addition, on the sagittal plane of the left margin of the inferior vena cava, the right renal artery was detected to locate above the left renal vein in 1 case (1.4%), posterior in 26 cases(37.1%), and below in 43 cases (61.4%). Based on this finding, 11 patients with right kidney cancer combined with venous tumor thrombus, admitted to Shandong Provincial Hospital Affiliated to Shandong First Medical University from June 2016 to December 2019, were retrospectively analyzed. The average age of the patients was(58.7±6.8)(45-68) years old. The CT three-dimensional reconstruction of the renal blood vessels was shown on the sagittal plane of the right margin of the aorta before the operation, and the right renal artery was detected to locate above the left renal vein in 0 cases, posterior in 7 cases, and lower in 4 cases. On the sagittal plane of the left margin of the inferior vena cava, the right renal artery was detected to locate above the left renal vein in 0 case, behind in 3 cases, and below in 8 cases. Renal tumors are located in the upper middle in 5 cases and in the lower middle in 6 cases. The maximum diameter of the tumor to be resected was 8.5-12.0 cm, with an average of (10.0±1.4) cm. Among them, 4 cases had Mayo grade 0 tumor thrombus, 4 cases were grade Ⅰ tumor thrombus, and 3 cases were grade Ⅱ tumor thrombus. All 11 cases underwent transperitoneal laparoscopic surgery. During the operation, it was found that the relationship between the right renal artery and the left renal vein was consistent with the preoperative three-dimensional reconstruction of renal blood vessels. The modified right renal artery dissection method was used, that is, the right renal artery was detected and ligated between the inferior vena cava and the aorta, using the left renal vein as a mark, and then the right kidneys and vein tumor thrombi were removed.Results:All of the 11 operations in this group were completed successfully. The operation time was (110.5±29.8)(70-150) min, the average time of right renal artery dissection was(28.5±5.8)(16- 33) min, and the amount of intraoperative bleeding was(112.7±83.5)(20-300) ml. No serious complications occurred during the operation in 11 cases. Postoperative pathological examination showed 10 cases of clear cell carcinoma and 1 case of papillary cell carcinoma. The postoperative hospital stay was 4.2 (4.18±0.75) days. There were no complications such as secondary bleeding, infection, lower extremity venous thrombosis or pulmonary embolism. All 11 patients were followed up for 3 to 42 months, with an average of(19.5±12.1) months. One patient died 23 months after the operation, and no tumor recurrence or metastasis occurred in the remaining patients.Conclusions:When the right renal artery runs to the left edge of the inferior vena cava, it is mostly behind the left renal vein. In the laparoscopic resection of right renal cancer with venous tumor thrombus, the modified right renal artery dissection method can quickly find and dissociate the right renal artery. The operation time is short, the intraoperative bleeding is less, and no postoperative complications occur.

Objective:To investigate the feasibility of cone-beam CT (CBCT) in evaluating the thickness of cortical bone in jaw bone.Methods:Sixty patients [twenty-three for males and forty-seven for females, at an average age of (43.8±1.7) years] from Center of Stomatology, The First Affiliated Hospital of USTC & Anhui Provincial Hospital with 63 operational regions were included in the present study. Totally 63 bone sections from these areas were all selected at last. Case Viewer and oral dynamic system were used for the measurements in sections and CBCT graphs of the cortical bone thicknesses at alveolar ridges. Paired samples t test was performed to compare the difference between CBCT measurement and Case Viewer measurement. Results:The cortical bone thicknesses measured by Case Viewer were (1.20±0.75), (0.68±0.46) and (1.48±0.77) mm in the posterior, maxillary posterior and mandibular posterior areas, respectively. The cortical bone thicknesses measured by dynamic navigation software were (1.14±0.77), (0.64±0.24) and (1.41±0.83) mm in the posterior, maxillary posterior and mandibular posterior areas, respectively. There were no significant differences between either the two methods or the different areas ( P>0.05). Conclusions:CBCT would be a useful equipment for the analysis of cortical bone thickness with a reliable and convincible accuracy.

Objective:To analyze the changes on the rates of prevalence, awareness and treatment of hypertension as well as the differences of the disease by demographic and economic factors, among adult farmers in nine provinces of China.Methods:Adult farmers, (including fishermen and hunters) with completed data on demographics, socio-economic characteristics, disease histories and physical measurements were selected from the 1991-2015 China Health and Nutrition Survey. Hypertension was defined based on the Chinese guidelines. Multivariate logistic regression was used to analyze the influence of demographic and economic factors on the rates of prevalence, awareness and treatment of hypertension among those adult farmers in 2015.Results:A total of 18 236 participants were included. From 1991 to 2015, rates of prevalence, awareness and treatment of hypertension among the adult farmers in nine provinces all significantly increased ( P<0.05). Results from the multivariate analysis showed that farmers aged ≥45 years were 98 % more likely to suffer from hypertension than those aged 18-44 years. Farmers who were overweight or obese were 1.58 times and 5.21 times more likely to suffer from hypertension than those in the control group (BMI<24.0 kg/m 2), respectively. The rates on awareness of hypertension among farmers with junior high school education ( OR=0.23) or above ( OR=0.12) or with junior high school education ( OR=0.30) were both lower than those with primary school education or below. Rates on the awareness and treatment of hypertension in obese farmers were 5.77 times and 7.52 times of those in the control group. Conclusions:The rates of prevalence of hypertension showed increasing trends during 1991-2015, with a slower increase in the rates of awareness and treatment in the farmers. Age ≥45 year-olds, and being obese were the risk factors for farmers to have hypertension, which suggested the above population should be focused on hypertension prevention strategy and practice.
