1.Research progress on immunotherapy for nasopharyngeal carcinoma
Chinese Journal of Radiation Oncology 2021;30(4):407-412
Nasopharyngeal carcinoma (NPC) is a malignant carcinoma that is closely associated with Epstein Barr virus (EBV) infection. After the comprehensive treatment based on modern intensity-modulated radiation therapy, the oncological outcomes can be further improved. The main target of treatment is to increase the efficacy of patients with high risk and recurrent/metastatic (R/M) NPC. Recently, continuous progress has been made in the application of immunotherapy in the field of cancer treatment. Based on the accumulated knowledge on EBV antigen and immune checkpoint inhibitors, significant progress has been made in use of immunotherapy in treating R/M-NPC. Immunotherapy combined with radiotherapy or chemoradiotherapy will become the hot spot in the clinical management of patients with newly-diagnosed high-risk NPC.

OBJECTIVE To observe the sterilization effect of nanometer photocatalysis air sterilizer mounted in hospital.METHODS We carried out a dynamic survey on air average numbers of colony through field experiment and practical operation.RESULTS The field experiment displayed that the air bacterium dissolution rate was 55.64-75.94% and the bacterium content degraded as time extended,after nanometer photocatalysis air sterilizer been used 1-2 h;the result of practical operation in four seasons of the year revealed that the average bacterium colony numbers in each ward region was lower than before sterilizer mounted,the air bacterium dissolution rate was 73-82.3% in the third ward region and 44.5-76.3% in the fourth ward region.CONCLUSIONS It is effective to use the nanometer photocatalysis air sterilizer to sterilize the air in hospital under the condition of inspection.The airflow of the central air conditioning can practice the air sterilization function more validly.

Lung cancer displays the highest morbidity and mortality worldwide. Non-small cell lung cancer (NSCLC) is the most com-mon type of lung cancer. In-depth research was performed on the pathogenesis and biological behavior of lung cancer and the im-provement of genetic testing level. The discovery of drugs targeting epidermal growth factor receptor and anaplastic lymphoma kinase plays a significant role in individual treatment of advanced NSCLC. BIM is a protein in the Bcl-2 family that promotes apoptosis, which leads to cell death. The BIM expression level and polymorphism can influence the therapeutic effect of targeted therapy and chemo-therapy on advanced NSCLC. Therefore, this review summarizes BIM and its effects on targeted therapy and chemotherapy for ad-vanced NSCLC.

Chang-Kang-Fang (CKF) formula, a Traditional Chinese Medicine (TCM) prescription, has been widely used for the treatment of irritable bowel syndrome (IBS). However, its potential material basis and underlying mechanism remain elusive. Therefore, this study employed an integrated approach that combined ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) with network pharmacology to systematically characterize the phytochemical components and metabolites of CKF, as well as elucidating its underlying mechanism. Through this comprehensive analysis, a total of 150 components were identified or tentatively characterized within the CKF formula. Notably, six N-acetyldopamine oligomers from CicadaePeriostracum and eight resin glycosides from Cuscutae Semen were characterized in this formula for the first time. Meanwhile, 149 xenobiotics (58 prototypes and 91 metabolites) were detected in plasma, urine, feces, brain, and intestinal contents, and the in vivo metabolic pathways of resin glycosides were elaborated for the first time. Furthermore, network pharmacology and molecular docking analyses revealed that alkaloids, flavonoids, chromones, monoterpenes, N-acetyldopamine dimers, p-hydroxycinnamic acid, and Cus-3/isomer might be responsible for the beneficial effects of CKF in treating IBS, and CASP8, MARK14, PIK3C, PIK3R1, TLR4, and TNF may be its potential targets. These discoveries offer a comprehensive understanding of the potential material basis and clarify the underlying mechanism of the CKF formula in treating IBS, facilitating the broader application of CKF in the field of medicine.
