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.

The accumulation of fatigue during military operations may lead to decreased operational efficiency and non-combat attrition,which can impact combat effectiveness.On-site monitoring and evaluation of fatigue during military operations,as an important means to keep track of military operations and bring about quick changes in training,underlie the combat effectiveness of military personnel.Focusing on the on-site monitoring and evaluation methods of fatigue during military operations,this paper reviews the determinants of such fatigue as well as on-site monitoring and comprehensive evaluation methods so as to provide reference for accurate and efficient evaluation of fatigue during military operations and for early warning of such fatigue.

Objective: To analyze the treatment effect of patients with glioblastoma (GBM) and explore prognostic factors. Methods: The clinical data of 635 patients diagnosed as GBM at Neurosurgical Oncology Department Ⅳ of Beijing Tiantan Hospital, Capital Medical University from January 2007 to March 2018 were retrospectively reviewed. There were 386 males and 249 females with an age of (48.7±11.8) years (range: 18-75 years). Patients were divided into three groups according to the time of admission: 2007-2010 group(n=174), 2011-2014 group (n=237) and 2015-2018 group (n=224). Kaplan-Meier plot was used to analyze the effects of different treatment periods, treatment schemes and clinical factors on the survival of patients with GBM. Cox proportion hazard regression analysis was used to identify independent prognostic factors. Results: The median progression-free survival (PFS) and overall survival (OS) of patients in 2007-2010 group, 2011-2014 group, 2015-2018 group was 9.0 months (95% CI: 7.5-10.5), 10.0 months (95% CI: 8.8-11.2), 12.0 months (95% CI: 10.7-13.3) and 17.0 months (95% CI: 13.2-20.8), 20.0 months (95% CI: 16.9-23.1), 23.0 months(95% CI: 17.5-28.5), respectively. The PFS and OS of patients improved significantly over the years (χ²=9.693, P=0.008 and χ²=8.616, P=0.013). Multivariate survival analysis showed that age, extent of resection, radiotherapy and tumor distant dissemination were independent prognostic factors (all P<0.05). Conclusions With the continuous development of clinical treatment regimen, the therapeutic effect of Chinese GBM patients has improved remarkably. Age, extent of resection, radiotherapy and tumor distant dissemination are independent prognostic factors associated with survival time.

Programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) blocking therapy has become a major pillar of cancer immunotherapy. Compared with antibodies targeting, small-molecule checkpoint inhibitors which have favorable pharmacokinetics are urgently needed. Here we identified berberine (BBR), a proven anti-inflammation drug, as a negative regulator of PD-L1 from a set of traditional Chinese medicine (TCM) chemical monomers. BBR enhanced the sensitivity of tumour cells to co-cultured T-cells by decreasing the level of PD-L1 in cancer cells. In addition, BBR exerted its antitumor effect in Lewis tumor xenograft mice through enhancing tumor-infiltrating T-cell immunity and attenuating the activation of immunosuppressive myeloid-derived suppressor cells (MDSCs) and regulatory T-cells (Tregs). BBR triggered PD-L1 degradation through ubiquitin (Ub)/proteasome-dependent pathway. Remarkably, BBR selectively bound to the glutamic acid 76 of constitutive photomorphogenic-9 signalosome 5 (CSN5) and inhibited PD-1/PD-L1 axis through its deubiquitination activity, resulting in ubiquitination and degradation of PD-L1. Our data reveals a previously unrecognized antitumor mechanism of BBR, suggesting BBR is small-molecule immune checkpoint inhibitor for cancer treatment.
