Glioblastoma multiforme (GBM,WHO grade IV) contains some glioma stem cells which have unique self-renewal capacity and multilineage potency.There are numerous neural stem cells in the subventricular zone (SVZ) of adult human brain;it may also act as a storehouse of glioma stem cells that can promote the development and recurrence of a tumor.GBM involving SVZ is prone to early recurrence and intracranial metastasis after resection,so irradiation of the SVZ potentially influences the survival of GBM patients.This review provides a summary of related experimental and clinical studies,and discusses the value of irradiation of the SVZ in GBM patients and the direction of future research.

Objective: To analyze the etiological characteristics of an outbreak of Campylobacter foodborne disease in a middle school in Suzhou City, so as to provide insights into the identification of pathogenic factors of Campylobacter foodborne disease outbreaks. Methods: Eighteen anal swabs from patients, 10 anal swabs from canteen workers, 43 food samples, 2 drinking water samples, 2 food original material samples and 31 environmental samples were collected, and the pathogens were rapidly screened using the gastrointestinal infection detection strip. The pathogens were isolated and cultured using the double-pore filtration membrane method, and cluster analysis of bacterial isolates was performed using pulsed field gel electrophoresis ( PFGE ). In addition, the susceptibility of Campylobacter isolates to antibiotics was tested using the Campylobacter agar dilution method. Results: A total of 63 cases with Campylobacter infections were reported, and the major clinical symptoms included diarrhea ( 51 cases, 80.95% ) and fever ( 39 cases, 61.90% ), while no inpatients or deaths were found. Twelve Campylobacter-positive samples were detected, including 11 anal swabs sampled from patients and one food original material sample. Among the 11 positive anal swabs, there were 10 samples positive for Campylobacter jejuni and one sample positive for C. coli, and of the one positive food original material, C. coli was identified. PFGE analysis showed that 10 C. jejuni isolates of had 100.0% homology, and these 10 isolates were 100.0% resistant to naphthyridic acid, ciprofloxacin and tetracycline, appearing multidrug resistance. Conclusions This is an outbreak of foodborne disease caused by C. jejuni infections. Gastrointestinal infection detection strips, double-pore filtration membrane and PFGE typing are rapid and accurate to identify pathogenic factors.

ObjectiveTo understand the health information needs of chronic disease inpatients and the current utilization of community health resources， and to analyze the influencing factors， so as to provide basis for personalized and high-quality health education for chronic disease inpatients and to guide them to make full use of community health resources. MethodsFrom November 2020 to February 2021， we conducted a face-to-face multi-center clinical epidemiological survey with paper questionnaire in three general hospitals of Shanghai. The study included 404 inpatients with diabetes， hypertension， coronary heart disease， chronic respiratory diseases， cancer and other chronic diseases. Results94.01% of the 404 respondents had different needs for disease or health related information， and there was no significant difference between patients of different ages， genders and educational backgrounds in their needs for health knowledge. Among these patients， only 39.11% of them participated in the establishment of a card for chronic disease management in the community or signed for a family doctor. The participation rate of male patients was lower than that of female patients （P<0.05）. ConclusionPatients with chronic diseases have a high demand for health related information， and we need to provide health information in multiple ways. We should increase investment in community health resources， improve service quality， and guide residents with chronic diseases to make full use of community health resources.
