Glioblastoma (GBM) is the most malignant primary brain tumor, and it has very poor prognosis. In recent years, the immunotherapy has become a hot issue in the treatment of malignancies. The traditional treatment regimen combined with immunotherapy might make a progress in the diagnosis and treatment of GBM. This paper reviews the explanation of the traditional chemoradiotherapy affecting the body's anti-tumor and immunity mechanism, and the current achievement of standard chemoradiotherapy combined with immunotherapy, to explore the potential benefits to GBM patients.

Objective: This study aimed to explore the relationships between various exercise components (frequency, intensity, duration) and social anxiety. Methods: A sample of 844 college students in China participated in this study. The Physical Activity Rating Scale-3 assessed participants’ daily physical activity. Social anxiety levels were measured using the Liebowitz Social Anxiety Scale. A questionnaire was developed to collect demographic information and examine the relationships between exercise components and social anxiety levels. Results: One-way analysis of variance revealed significant differences in social anxiety levels across varying physical activity intensities. Specifically, students engaging in high levels of physical activity exhibited the lowest social anxiety. Post hoc analyses identified that exercise frequency F3 (p<0.01), exercise duration D5 (p<0.01), and exercise intensity I3 (p<0.01) were significantly associated with the lowest social anxiety levels. Among these components, regression analysis indicated that exercise duration (p<0.01) had the most substantial impact on social anxiety levels, followed by exercise frequency (p<0.05). In contrast, exercise intensity (p>0.05) did not significantly affect social anxiety levels. Conclusion The most influential factors associated with decreased social anxiety were: 1) moderate to high exercise intensity, 2) exercise duration of at least one hour, and 3) exercise frequency of at least 1–2 times per week. Among these factors, exercise duration and frequency demonstrated significantly stronger associations with reduced social anxiety. Therefore, it is advisable to prioritize exercise duration and frequency in physical activity programs for college students to reduce social anxiety and achieve more substantial outcomes.

BACKGROUND:Exercises can reduce blood lipids and slow down the development of atherosclerosis.Atherosclerosis begins with mitochondrial dysfunction,and prohibitin 2 is involved in mitophagy by endurance training. OBJECTIVE:To explore the role of endurance training in the intervention of prohibitin 2 protein in the mitophagy autophagy pathway in atherosclerosis. METHODS:A total of 40 Wistar rats were randomly divided into control group,exercise group,atherosclerosis group and atherosclerosis combined with exercise group,with 10 rats in each group.A rat model of atherosclerosis was constructed by combining a high-fat diet(9 weeks)with vitamin D injections(weeks 1,3,and 6)in the latter two groups,while the two exercise groups were subjected to progressing intensity endurance training for 9 weeks.After the intervention,lipid and pathological detections were conducted to observe the modeling and interventional effects.Mitochondrial membrane potential and mitophagy proteins were detected by microplate reader and western blot.Immunofluorescence staining was used to observe the co-localization of mitophagy proteins in aortic tissue. RESULTS AND CONCLUSION:Lipid and pathological sections showed that compared with the atherosclerosis group,the serum low-density lipoprotein cholesterol and total cholesterol levels and aortic lipid deposition area were significantly reduced in the atherosclerosis combined with exercise group(P<0.001).The results of mitochondrial membrane potential showed that the significant decrease in mitochondrial membrane potential of the aorta in the atherosclerosis combined with exercise group was reversed(P<0.01).The results of western blot assay showed that compared with the control group,the mitochondrial protein expression of prohibitin 2,LC3Ⅱ/Ⅰ,PINK1 and Parkin was significantly increased(P<0.05),and the protein expression of PARL and PGAM5 decreased(P<0.05).Compared with the atherosclerosis group,the protein expression of PINK1 and Parkin in the mitchondria of rats in the atherosclerosis combined with exercise group was significantly decreased(P<0.05),and the protein expressions of prohibitin 2,LC3Ⅱ/Ⅰ,PARL and PGAM5 were significantly increased(P<0.05).Immunofluorescence results showed that compared with the control group,the co-localization of LC3 and PINK1 with TOMM20 was significantly increased in the atherosclerosis group(P<0.05),while compared with the atherosclerosis group,the co-localization of LC3 and PINK1 with TOMM20 was significantly increased in the atherosclerosis combined with exercise group(P<0.05).Co-localization of LC3 and PARL with prohibitin 2 was significantly increased in the atherosclerosis group compared with the control group(P<0.01),co-localization of LC3 with prohibitin 2 was significantly increased in the atherosclerosis combined with exercise group compared with the atherosclerosis group(P<0.01),and co-localization of PARL protein with prohibitin 2 was significantly decreased in the atherosclerosis combined with exercise group compared with the atherosclerosis group(P<0.01).To conclude,endurance training can induce the expression of prohibitin 2 in the inner mitochondrial membrane and promote the binding of prohibitin 2 to the mitophagy junction protein to complete mitophagy,restore mitochondrial function,and slow down the occurrence of atherosclerosis.

Objective:To analyze the prognosis factors of cerebrospinal fluid (CSF) spread after surgery in glioblastoma (GBM) patients when tumors progressed and the effect factors on prognosis.Methods:A retrospective study was conducted on 124 patients who were pathologically diagnosed as glioblastoma after surgery, and found tumor progressed during regularly follow-up at Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University between January 2009 and August 2017.There were 82 males and 42 females, aged 47.9 years(range: 19 to 75 years) .Patients were divided into local recurrence group(96 cases) and CSF spread group (28 cases) .Clinical data were recorded in detail and compared by independent sample t test or χ 2 test.Kaplan-Meier survival curves was used to demonstrated the distribution of progression free survival (PFS) overall survival (OS) and post progression survival (PPS), and differences between local recurrence and CSF spread groups were assessed by Log-rank test.Cox proportion hazard regression analysis was used to identify independent prognostic factors. Results:Logistics regression analysis showed ventricle entry was the only prognosis factor of CSF spread ( OR=2.667, 95 % CI: 1.128 to 6.304, P=0.025).No significant distinction was observed in PFS between CSF spread group and local recurrence group(7.0 months vs.9.3 months, P=0.066).However, OS and PPS were substantially shortened in CSF spread group (13.0 months vs.23.0 months, P=0.011; 6.0 months vs.11.0 months, P=0.022, respectively).Mutations of isocitrate dehydrogenase gene, distant spread, gross-total resection, Ki-67 index>30% were independent prognostic factors of GBM patients. Conclusions:Ventricle entry is a prognosis factor for CSF spread, after which the median OS and PPS are markedly diminished.However, ventricle entry is not independent prognosis factor shortening survival.

Objectives:To explore the prognostic factors of primary central nervous system lymphoma(PCNSL) and to analyze the efficacy of different treatment methods.Methods:Clinical data of 4 812 patients with PCNSL in SEER database from January 1975 to December 2016 were retrospectively analyzed.Among them, 2 831 were male and 1 981 were female, the ratio of male to female was 1.4∶1.0.There were 2 236 cases(46.47%) under 60 years old, 1 718 cases(35.70%) aged 60 to 74 years old, and 858 cases(17.83%) aged 75 years old or above. Two thousand four hundred and seventeen cases(50.23%) had supratentorial tumors, 299 cases (6.21%) had infratentorial tumors, and 554 cases(11.51%) had multiple brain tumors, 1 542 cases (32.04%) were other or unspecified location.Three thousand five hundred and thirteen cases(73.00%) had diffuse large B-cell lymphoma (DLBCL), 234 cases(4.86%) had non DLBCL, 1 065 cases (22.13%) had other or unspecified types of tumor.The treatment included 2 011 cases (41.77%) of biopsy, 61 cases (1.27%) of subtotal resection(STR), 54 cases (1.12%) of gross total resection(GTR), 2 384 cases (49.54%) of biopsy and chemotherapy, 159 cases (3.30%) of STR and chemotherapy, 144 cases (3.00%) of GTR and chemotherapy.Univariate and multivariate Cox regression models were used to analyze the prognostic factors affecting the overall survival of the patients.Fine-Gray test and competitive risk model were used to analyze the prognostic factors affecting cancer-specific survival.Kaplan-Meier method and Log-rank test was used for survival analysis.Results:Univariate and multivariate Cox regression analyses showed that age, race, marital status, tumor site, pathological subtype, surgery, chemotherapy, combined with other malignant tumors, and HIV infection were the independent prognostic factors affecting the overall survival of PCNSL patients.The results of Fine-Gray test and competitive risk model analyses showed that age, race, marital status, tumor location, pathological subtype, surgical method, chemotherapy, combined with other malignant tumors, and HIV infection were independent prognostic factors affecting cancer-specific survival, while gender and radiotherapy had no significant correlation with cancer-specific survival.Compared with biopsy, PCNSL patients may benefit from surgical resection (STR: HR=0.805, 95% CI:0.656?0.989, P=0.04; GTR: HR=0.521, 95% CI:0.414?0.656, P<0.01).Kaplan-Meier survival analysis showed that the median survival time of biopsy+chemotherapy group was 28 months (95% CI:24.497?31.503), 2 months (95% CI:1.756?2.244) in the biopsy group, 2 months (95% CI:1.410-2.590) in the STR group, 19 months ( 95%CI:0?39.311) in the biopsy+chemotherapy group, 67 months (95% CI:46.187-87.813) in the STR+chemotherapy group, 84 months (95% CI:57.448?110.552) in the GTR+chemotherapy group.The median survival time of patients with different treatment methods was statistically significant ( P<0.01). Conclusions:Surgical resection may improve the prognosis of some PCNSL patients.Patients who have access to receive GTR or STR combined with chemotherapy may have prolonged Cancer-specific survival.
