With the development of modern radiotherapy techniques,radiotherapy has been widely used in the multimodality therapy for various malignant tumors,including head and neck cancers such as nasopharyngeal cancer and laryngeal cancer.A combination of surgery and radiochemotherapy significantly improves patients' cure rate and survival time;however,with the increase in survival time,some patients receiving radiotherapy develop marked cognitive impairment.Ionizing radiation-induced cognitive impairment mainly nanifests as hippocampus-dependent cognitive impairment,which is associated with inhibited hippocampal neurogenesis due to ionizing radiation.Therefore,it is necessary to investigate the mechanisms of the inhibition of hippocampal neurogenesis by ionizing radiation.This article reviews the molecular mechanism of neurogenesis disorders induced by ionizing radiation.

Objective To analyze the risk factors of mucous plug caused byMycoplasma pneumoniae pneumonia (MPP) in children and guide clinical therapy to decrease the incidence of sequela caused by airway inlfammatory obstruc-tion.Methods We conducted a retrospective study of the clinical data of 116 children with MPP who received ifber broncho-scope from January 2012 to January 2014 admitted to the respiratory department of the Children's Hospital of Hebei provience. Based on the airway mucosal lesions seen through the bronchoscope, the subjects were divided into the mucous plug group (n=67) and the control group (n=49). Gender, age of onset, febrile course, pleural effusion, white blood cell counts, neutrophil ratio, C reactive protein (CRP), serum lactate dehydrogenase level (LDH), initial time of received macrolides and ifber bronchoscope were compared between the two groups. If the Results of single factor analysis showedP<0.05, the indicators were analyzed by the logistic regression analysis. The receiver operator characteristic (ROC) curve was drawn to evaluate the predictability of logistic regression model.Results The Results of single factor analysis showed that age of onset, febrile course, CRP, serum LDH, pleural effusion cases in the mucous plug group were higher than those in control group (P<0.05). The Results of the logis-tic regression analysis showed that older than three years (OR=7.45), febrile course more than 10 days (OR=4.01), the level of CRP and LDH higher than 40 mg/L (OR=5.41) and 350 U/L (OR=3.63) were respectively the risk factors of mucous plug caused by MPP in children. The area under the ROC curve is 0.846 (95%CI: 0.773-0.919,P=0.000).Conclusions MPP children with age older than three years, or with febrile course more than 10 days, or with the level of CRP and LDH higher than 40 mg/L and 350 U/L has the possibility of forming a mucous plug.

Objective:To investigate and analyze the current status of multimodality therapy for resectable gastric cancer, aiming to provide reference for optimizing the multimodality treatment strategy for gastric cancer.Methods:Clinical data of patients diagnosed with gastric adenocarcinoma undergoing radical gastrectomy in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. Clinical characteristics, preoperative medical comorbidities, pathological features, surgical and perioperative status and clinical efficacy were recorded. The gap between the diagnosis and treatment procedures and the standard guidelines was analyzed. The changes in the multimodality treatment patterns for gastric cancer were understood.Results:A total of 265 patients were included in this study. All patients were divided into two cohorts: early[2008] and late[2013] cohorts. In the early cohort, 127 patients were assigned, and 138 cases in the late cohort. In the early cohort, 67 patients (52.8%) underwent D 2 lymph node dissection, significantly less than 83 patients (60.1%) in the late cohort ( P<0.01). In the early and late cohorts, the proportion of patients with the number of lymph node dissection of ≥15 was 5.5% and 52.8%( P<0.01). The median number of lymph node dissection was increased from 6 to 16. The proportion of patients receiving neoadjuvant chemotherapy in the early and late cohorts was 2.4% and 3.6%( P=0.55). In the early cohort, the proportion of patients treated with postoperative chemotherapy and postoperative adjuvant chemoradiotherapy was 62.6% and 2.4%, significantly higher compared with 58.0% and 8.0% in the late cohort ( P=0.04). In addition, the proportion of patients receiving postoperative chemotherapy in the early cohort was 62.2%( n=79) and 58.0%( n=80) in the late cohort ( P=0.48). Conclusions:Although the level of radical gastrectomy has been continuously improved and standardized in China, which still lags behind the standard D 2 radical gastrectomy in Japan and South Korea. Adjuvant therapies including postoperative adjuvant radiotherapy can bring clinical benefits. However, the proportion of patients receiving adjuvant therapy is still low, and the multimodality therapy of gastric cancer should be widely applied.
