1.The function of T helper type 17 cell in intestinal mucosal immunity
International Journal of Pediatrics 2011;38(2):155-158
The intestinal mucosa is the biggest lymph organ in human body, which consists of the first line of defensive system with the respiratory mucosa and urinary mucosa. The intestinal mucosa is responsible to defend bacteria, viruses, dietary pathogens, non-steroid anti-inflammatory drug and so on. If the intestinal mucosal immune system is destroyed, the human will suffer many diseases such as infectious diseases,autoimmune diseases. Therefore, it plays an important part in physical health. T helper type 17 (Th17) cells different from Th1 cells and Th2 cells are a distinct lineage of T cells. The discovery of Th17 cells has ruined the constitutional pattern of Th1/Th2. Th17 cells, which are important parts of intestinal mucosal immune system,play critical roles in intestinal autoimmune diseases, tissue inflammation and the infection of various pathogenic bacteria. This paper will review the differentiation of Th17 cell and its function in intestinal mucosal barrier,intestinal autoimmune diseases and intestinal infectious diseases.

6.Current status of mechanical thrombectomy for acute ischemic stroke
International Journal of Cerebrovascular Diseases 2016;24(1):63-67
Before irreversible neuronal damage occurs, quickly and securely recanalize vessels and restore blood flow to save the ischemic penumbra tissue are the main therapeutic target for acute ischemic stroke (AIS). Currently, the method for recanalization in early AIS is intravenous thrombolysis, how ever, the effect of intravenous thrombolysis is often not satisfactory because of the reasons, such as its short treatment time w indow , low vascular recanalization rate, and high incidence of bleeding complications. In recent years, w ith the research and development of mechanical thrombectomy device and the development of interventional technology, the therapeutic time w indow of AIS has been significantly prolonged, the vascular recanalization rate has increased significantly, the clinical outcome has improved significantly, and the treatment of mechanical thrombectomy has show n good application prospects.
7.Safe margin of breast conserving surgery for breast cancer
Journal of International Oncology 2016;43(6):458-461
Breast conserving surgery has become the first choice for the treatment of early breast cancer.However,the safety margin is still one of the important issues for surgeons in the implementation of breast conserving surgery.Because variety of clinical factors have some effects on the safety margin,at present,no consensus on safe margin of breast conserving surgery is reached,and the controversy still goes on.
8.Influence of bedside evaluation of deglutition function and predictive nursing intervention on patients with dysphagia
Chinese Journal of Practical Nursing 2008;24(9):21-23
Objective To evaluate the application effect of bedside evaluation of deglutition function and predictive nursing intervention on patients with dysphagia in neurology department. Methods 320 Patients with dysphagia were divided into the observation group and control group with 160 cases in each group. The observation group was given admission nursing evaluation and bedside evaluation of deglutition function while the control group only received admission nursing evaluation. The incidence of complications in each group were assessed. Results The incidence of complications such as aspiration, pulmonary infection, asphyxia and metabolic disturbance in the observation group was lower than that of the control group(P<0.01).Conclusion The bedside evaluation of deglutition function could accurately evaluate the degree of swallowing disorder and supply theoretical evidence for predictive nursing intervention by in structing clinical application of selective measures for patients with dysphagia. This could guarantee safe food intake and reductive incidence of complications of patients. So we advocated that bedside evaluation of deglutition function should be a routine admission nursing evaluation in neurology department.
