Objective:To analyze the prognostic influencing factors in patients with isocitrate dehydrogenase (IDH) wild-type glioma, and further evaluate the value of surgical resection in prognosis.Methods:The clinical data and molecular pathological information of 647 patients with IDH wild-type glioma were retrieved from the Chinese Glioma Genome Atlas (CGGA) database (from 2006 to 2019). The clinical characteristics were recorded, including gender, age, initial symptoms, preoperative Karnofsky performance status (KPS) score, tumor location, tumor laterality, extent of resection, O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status and postoperative treatment. Kaplan-Meier survival curve was plotted to calculate overall survival (OS) and progression-free survival (PFS), and comparisons were performed using the log-rank test. Multivariate Cox regression analysis was used to identify the independent influencing factors of prognosis in patients with IDH wild-type glioma.Results:Among the 647 patients with IDH wild-type glioma, there were 120 cases of WHO grade Ⅱ, 115 cases of grade Ⅲ, and 412 cases of grade Ⅳ; the median OS was 20.3 months. There were statistical differences in age, initial symptoms, tumor location, preoperative KPS score, extent of resection, MGMT promoter methylation status and postoperative treatment among patients with different WHO grades (P<0.01), but there were no statistical difference in gender and tumor laterality (P>0.05). The median OS and PFS in patients with WHO grade Ⅱ were significantly longer than those in patients with WHO grade Ⅲ and WHO grade Ⅳ (169.9 months vs. 24.7 and 14.4 months, 138.8 months vs. 17.7 and 11.4 months), the indexes in patients with WHO grade Ⅲ were significantly longer than patients with WHO grade Ⅳ, and there were statistical differences (P<0.05). The median OS and PFS in patients with total resection were significantly longer than those in patients with subtotal resection and partial resection (37.2 months vs. 20.3 and 8.5 months, 29.5 months vs. 17.6 and 6.0 months), the indexes in patients with subtotal resection were significantly longer than patients with partial resection, and there were statistical differences (P<0.05). Among 153 patients with MGMT promoter methylation who received postoperative chemoradiotherapy, the median OS and PFS in patients with total resection (67 cases) were significantly longer than those in patients with subtotal resection (64 cases) and partial resection (22 cases): 28.8 months vs. 18.4 and 9.0 months, 25.6 months vs. 16.6 and 6.5 months), the indexes in patients with subtotal resection were significantly longer than patients with partial resection, and there were statistical differences (P<0.05). Among 202 patients with MGMT promoter non-methylation who received postoperative chemoradiotherapy, the median OS and PFS in patients with total resection (81 cases) were significantly longer than those in subtotal resection (81 cases) and partial resection (40 cases): 31.3 months vs. 21.9 and 14.0 months, 22.7 months vs. 16.8 and 9.7 months, and there were statistical differences (P<0.05), but there were no statistical difference in the indexes between patients with subtotal and patients with partial resection (P>0.05). Multivariate Cox regression analysis result showed that age, extent of resection, WHO grade (grade Ⅲ/grade Ⅳ) and postoperative treatment were independent OS and PFS influencing factors in patients with IDH wild-type glioma (OS: HR = 1.327, 3.295, 3.406/7.964 and 1.597; 95% CI 1.079 to 1.633, 2.627 to 4.132, 2.225 to 5.216/5.339 to 11.880 and 1.288 to 1.981; P<0.01. PFS: HR = 1.282, 2.655, 3.143/6.511 and 1.477; 95% CI 1.039 to 1.583, 2.123 to 3.322, 2.049 to 4.819/4.376 to 9.690 and 1.181 to 1.849; P<0.05 or <0.01).Conclusions:The age, extent of resection, WHO grade and postoperative treatment are independent prognosis influencing factors in patients with IDH wild-type glioma. Treatment strategies should fully consider the clinical and molecular pathological characteristics to achieve maximal safe tumor resection and optimal survival benefit.

Objective:To observe the therapeutic effect of combining low-frequency pulsed electrical stimulation with Beckman oral muscle exercise training in relieving drooling among persons with Parkinson′s disease (PD).Methods:A random number table was used to divide 120 PD patients with drooling into a mouth muscle training group, an electrical stimulation group, and an observation group, with 40 patients in each group. In addition to routine medication, the oral muscle training group was given Beckman oral muscle exercise training, the electrical stimulation group underwent low-frequency pulsed electrical stimulation treatment, while the observation group was provided with both. Before and after 4 weeks of treatment, the severity of salivation, the frequency of repeated empty swallowing, oral motor function, saliva secretion, and life quality of the three groups were evaluated using the Saliva Rating Scale (DRS), the Repeated Saliva Swallowing Test (RSST), oral motor function grading, the Parkinson′s Disease Saliva Clinical Scale (SCS-PD), saliva weighing, and the PD Quality of Life Scale (PDQ-39).Results:After the treatment the average DRS, SCS-PD, saliva weighing and PDQ-39 results of the observation group were significantly better than those before treatment and better than the other 2 groups′ averages. That group′s average RSST and oral motor function scores had increased significantly compared to before treatment, and compared with the other 2 groups′ averages at the same time point.Conclusions:Combining low-frequency pulsed electrical stimulation with Beckman oral muscle exercise can improve oral motor function, swallowing, and the life quality of PD patients who drool. It is more effective than electrical stimulation or oral muscle exercise training alone. Such combination therapy is worthy of clinical promotion and application.

ObjectiveTo investigate the possible mechanism of Shenqi Jianxin Formula （参芪健心方） in the treatment of chronic heart failure （CHF） from the perspective of pyroptosis. MethodsFifty-two rats were randomly divided into sham operation group （n=8） and modeling group （n=44）. In the modeling group， the anterior descending branch of the left coronary artery was ligated to construct CHF rat model. Forty successfully-modelled rats were randomly divided into model group， Entresto group， Shenqi Jianxin Formula group， MCC950 group and the combination group （Shenqi Jianxin Formula plus MCC950）， with 8 rats in each group. In Shenqi Jianxin Formula group， 7.4 g/（kg·d） of Shenqi Jianxin Formula was given by gavage， while in Entresto group， 68 mg/（kg·d） of Entresto suspension was given by gavage； in MCC950 group， MCC950 was injected intraperitoneally with 10 mg/kg once every other day， and in the combination group， 7.4 g/（kg·d） of Shenqi Jianxin Formula was given by gavage， and MCC950 was injected intraperitoneally with 10 mg/kg once every other day； 10 ml/（kg·d） of saline was given by gavage in the sham operation group and the model group. After 3 weeks of continuous intervention， serum brain B-type natriuretic peptide （BNP）， creatine kinase isoenzyme MB （CK-MB）， interleukin 1β （IL-1β）， and interleukin 18 （IL-18） levels were detected by ELISA； HE staining and MASSON staining were used to observe pathological changes in rat myocardium. Except for the Entresto group， western blot technique was used to detect the expression of NOD-like receptor protein 3 （NLRP3）， caspase-1， and apoptosis-associated speck-like protein possessing a caspase-recruiting domain （ASC）； RT-PCR was used to detect the expression of NLRP3 and caspase-1 mRNA. ResultsCompared with the sham operation group， HE staining of rats in the model group showed obvious myocardial injury， while MASSON staining showed increased area of collagen fibrosis， and serum BNP， CK-MB， IL-1β， IL-18， myocardial tissue NLRP3， caspase-1， ASC protein expression and NLRP3， caspase-1 mRNA expression were all elevated （P＜0.05）. Compared with those in the model group， cardiomyocyte injury of rats and collagen fibrosis area were reduced， and serum BNP， CK-MB， IL-1β， and IL-18 contents were all reduced in Shenqi Jianxin Formula group， Entresto group， MCC950 group， and the combination group； except for Entresto group， myocardial tissue NLRP3， caspase-1， ASC protein expression and NLRP3， caspase-1 mRNA expression were reduced in the remaining three medication group （P＜0.05）. Compared with Shenqi Jianxin Formula group， the MCC950 group and the combination group showed decreased serum IL-1β and IL-18 content， collagen fibrosis area， myocardial tissue NLPR3， caspase-1 protein expression， and caspase-1 mRNA expression， and decreased ASC and NLRP3 mRNA expression was shown in the combination group （P＜0.05）. Compared with MCC950 group， collagen fibrosis area was reduced， and serum IL-18 content， NLRP3， caspase-1 mRNA expression were reduced in the combination group （P＜0.05）. ConclusionShenqi Jianxin Formula can effectively improve the myocardial injury and heart failure in rats with CHF， and its mechanism may be related to the inhibition of cardiomyocyte pyroptosis through NLPR3/Caspase-1 pathway to reduce the level of intramyocardial inflammation. The combined use of MCC950 with Shenqi Jianxin Formula could more effectively inhibite myocardial pyroptosis， with better therapeutic result than single use of each part.

Objective: To investigate the willingness to accept preventive treatments and its related factors among college freshmen with latent tuberculosis infection (LTBI), so as to provide the evidence for preventive treatment intervention measures for students with LTBI. Methods: Cluster sampling method was used to select 368 LTBI freshmen from 8 colleges and universities in Changzhou in September 2023, who conducted a questionnaire survey on the willingness to receive preventive treatment. General demographic data were collected and relevant data were collected using tuberculosis knowledge scale, General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Adaptation, Partnership, Growth, Affection and Resolve (APGAR), and a self developed Stigma Scale. A binary Logistic regression model was constructed with the willingness to accept preventive treatment as the dependent variable to analyze the willingness to accept preventive treatment and the influencing factors. Results: A total of 253 LTBI college freshmen were willing to take preventive treatment, the acceptance rate was 68.75%. The rate of willingness to accept preventive treatment for LTBI was higher among students whose fathers had an education level of high school, compared to those whose fathers had an education level of junior high school or below ( OR =2.16, P <0.05). LTBI students whose per capita family income was >5 000-10 000 yuan and >10 000 yuan were more willing to accept LTBI preventive treatment than those whose per capita family income was <3 000 yuan ( OR =2.72, 4.46, P <0.05). LTBI students who engaged in physical exercise for more than 2 hours per week were more willing to accept than those who exercised less than 0.5 hours per week ( OR =1.91, P <0.05). LTBI students with high levels of tuberculosis knowledge and stigma were more likely to receive preventive treatment ( OR =1.18, 1.11, P < 0.05). LTBI students with high PHQ-9 ( OR =0.85) and GAD-7 ( OR =0.92) scores were more likely to refuse preventive treatment ( P <0.05). Conclusion The present study revealed a moderate level of willingness of LTBI students to preventive treatment in Changzhou City, and the acceptance is affected by family factors, healthy lifestyles, tuberculosis knowledge and psychological status.

Objective:To evaluate the value of the skeletal muscle index (SMI) and psoas major muscle index(PMI) measured at the third lumbar vertebra(L3) level in the evaluation on nutritional status and prognosis of cirrhosis patients with ascites.Methods:The clinical data of 102 patients with cirrhosis and ascites treated in our department between September 2018 and September 2022 was analyzed retrospectively, the skeletal muscle and psoas muscle area at L3 level were measured, and L3-SMI and L3-PMI were calculated. According to L3-SMI, patients were divided into the sarcopenia group (62 cases) and the normal muscle mass group (40 cases). Differences between the two groups were compared in terms of L3-SMI, L3-PMI, body mass index (BMI), albumin, the rate of re-admissions and mortality during follow-up. The value of each index in nutritional assessment was also explored.Results:L3-SMI, L3-PMI, and albumin in the sarcopenia group were significantly lower than those in the normal muscle mass group, with statistical significance ( P<0.01).The BMI of the sarcopenia group was lower than that of the normal muscle mass group, but the difference was not significant ( P>0.05). L3-PMI showed better performance in nutritional assessment compared with albumin and BMI. The rate of re-admissions and the mortality rate in the sarcopenia group during the follow-up period were significantly higher compared with the normal muscle mass group ( P<0.05). Conclusion:L3-SMI and L3-PMI can effectively reflect the nutritional status of cirrhosis patients with ascites, and are promising indicators for prognosis prediction in cirrhosis patients with ascites.

Objective:To observe the multimodal imaging characteristics of combined hamartoma of the retina and retinal pigment epithelium (CHRRPE).Methods:A cross-sectional study was conducted.Sixteen eyes of 16 patients with CHRRPE were enrolled in Second People's Hospital of Yunnan Province from March 2013 to July 2019.Fundus color photography, fundus autofluorescence (FAF), fluorescein fundus angiography (FFA), indocyanine green angiography (ICGA), optical coherence tomography (OCT), optical coherence tomography angiography (OCTA) and multicolor imaging were performed in all patients.The multimodal imaging characteristics were analyzed.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Second People's Hospital of Yunnan Province (No.20130106). Written informed consent was obtained from patients or their guardians prior to any medical examination.Results:Tumors were located in the posterior optic disc, and translucent glial lesions with unclear borders and slight elevations were observed.The surface of the lesions was attached by different degrees of fibroproliferative membrane, and the adjacent vessels were twisted and dilated.The tumors presented flat bulging green reflexes on the retina at the posterior pole by multicolor imaging, and OCT image showed thickened optic disc and retina near the optic disc, structural disorder, high reflectance of the surface, and low reflectance of the deep retina below the periretinal membrane.OCTA showed irregular blood flow signals, and the signal of retinal blood vessels was twisted and dilated.FAF showed that the autofluorescence intensity of tumors was weakened to different degrees.Early lesions presented different degrees of blocked fluorescence in FFA.Deformed and tortuous blood vessels were found in the eyes, and telangiectasia showing needle-like punctate strong fluorescence leakage was observed in severe eyes by FFA.ICGA showed no abnormal choroidal vessels.Conclusions:The main imaging features of CHRRPE include abnormal retinal blood vessels in the tumor area and fibrous proliferative membranes on the surface in color image; OCT shows that the retina and the retinal pigment epithelium are involved, and the retina in the tumor is thickened with disordered structure; high reflection OCTA shows irregular internal blood flow signals inside the tumor; FFA examination shows fluorescence obscuration and obviously tortuous retinal blood vessels.Multimodal imaging examinations are helpful for the diagnosis of CHRRPE.
