The system of college and university students serving as information members is the important approach for students to participate in teaching and management,which is important guarantee system to perfect and enhance teaching quality,and boost the educational reform. This article makes brief analysis of the function of college and university students seving as information members in information interacting,including the role of a bridge,the role of a regulation and the role of a supervision.It is very important to further exert and explore the students’ information member role in the teaching and the management.

Allergic asthma is a chronic obstructive disease of the airways characterized by airway hyperresponsiveness,inflammation and remodeling.Exhaled nitric oxide (eNO) level is highly correlated with eosinophilic airway inflammation.Since the advantage of noninvasion,convenience,and specificity of eNO measurement,it has been widely used as a biomarker.In this article eNO metabolism and its effects on airway physiology and pathophysiology are described.The usefulness of eNO in asthma diagnosis and management is discussed in detail.

In recent years,researches on many autoimmune diseases show that Th17 and follicular helper T cells(Tfh cells) induce the happening of many autoimmune diseases via IL-21,STAT3 or other cytokines and signaling pathway.IL-21,as the common cytokine of Th17 and Tfh cells,plays an important role on their differentiation and development and function playing.This paper reviews the role of Thl7 and Tfh cells as well as their cytokines in myasthenia gravis,systemic lupus erythematosus and inflammaotoy bowel disease.

Objective To explore the clinical nursing path teaching method application in children with mycoplasma pneumonia and its effect.Methods 93 higher vocational nursing students of two classes of Grade 2011 were chosen as the subjects,one class as the experimental group(46),and the other class as the control group(47).The traditional teaching method was used in the control group,while method of clinical nursing path was used in the experimental group.Two groups of nursing students were given closed book exams and questionnaires to evaluate teaching effectiveness of the two groups.SPSS 13.0 was used for statistical analysis,count data using x2 test,measurement data using t-test,test level α=0.05.Results The experimental group students' test scores were significantly higher than the control group(85.26 ± 3.57)vs.(76.39 ± 4.16),and the difference was statistically significant P=-0.02.The survey showed that there were more students in the experimental group than in the control group who made a positive comment on the questionnaire's role in helping improve students'learning autonomy,their critical thinking ability,and promote their grasp of the content of the disease.Conclusion Clinical nursing path teaching method as a new kind of teaching method,can improve the teaching effect.

Objective:To discuss the strategy and the scientific management of large medical equipment maintenance.Methods: The support technical service 2 maintenance strategy of the manufacturer were chosen by establishing the importance of two scientific management method, management measures and equipment maintenance.Results: The failure rate was reduced. The equipment utilization, medical management level was improved.Conclusion:Large medical equipment is the major hospitals in medical tests, treatment work of technical support and the material basis, do a good job in each big hospital equipment management and maintenance work is medical equipment can be effectively play, make full use of the key, is worth wide use in the medical community.

Purpose:The study of major point on differential diagnosis between the Kikuchi lymphadenitis and malignant lymphoma.Methods:7 cases difficult diagnosis of Kikuchi lymphadenitis were observed by histology and immunohistochemistry.Results:The common features in these 7 cases kikuchi lymphadenitis was (1) The lymphnode swelling after heat;(2)Multiple focus of lesion and in the pathologic areas, the cellular composition was dominated by striking blastic histiocytes and phagocytes, few plasmacytoid monocytes, T immunoblasts and T lymphocytes;(3) Absence of neutrophiles infiltration;(5)Variable amounts of mitotic figures. Conclusions:Author considered on the special clinical feature, multiple focus of leison, striking blastic histiocytes and phagocytes and few other cells mixed composition, and with variable amount of nuclear debris were major features of differential diagnosis between the Kikuchi lymphadenitis and malignant lymphoma.

Objective To compare the efficacy of peri -operative rehabilitation between the fast track ortho-pedics(FTO)and non -FTO with elderly femoral neck fractures.Methods 34 patients with elderly femoral neck fractures in the Nanjing Gaochun Hospital of Traditional Chinese Medicine during June 2014 to March 2015 were col-lected.All patients were divided into FTO group(n =17)and non -FTO group(n =17)randomly,the FTO group was treated with FTO and the non -FTO group was under routine perioperative rehabilitation program.Comparison were performed between two groups on postoperative by Harris score,patient satisfaction,visual analogue score (VAS), length of stay (LOS) and postoperative complication.Results All the 34 patients were followed up for 8 -16 months,average(12.0 ±2.4)months.There was no significant difference in VAS scores between the two groups (P >0.05).The VAS score in the postoperative group FTO[(1.8 ±0.7)points]was significantly lower than that in the non FTO group[(2.6 ±0.9)points],and the difference was statistically significant (t =1.389,P <0.05).There was no significant difference in Harris scores between the two groups(P >0.05).The Harris score in the FTO group [(84.9 ±3.7)points]was significantly higher than that in the non -FTO group[(72.3 ±5.2)points],and the difference was statistically significant(t =3.243,P <0.05).Conclusion FTO can effectively promote the surgical treatment,reduce the pain,recovery of hip joint function and improve patient satisfaction in elderly femoral neck frac-tures.

BACKGROUND:So far numerous theoretical studies have shown the treatment effect of stem cel transplantation for chronic complications of diabetes, while its treatment effects on diabetic nephropathy have not yet been confirmed in animal models. OBJECTIVE:To investigate the protective effect of bone marrow mesenchymal stem cel transplantation on the kidney in rat models of diabetes. METHODS:Rats were fed with high-sugar and high-fat diet for 4 weeks, and then were given injection of streptozotocin to establish type 2 diabetic rat models. At 2 days after modeling, bone marrow mesenchymal stem cel s were injected via the tail vein (stem cel transplantation group). In the meanwhile, control and diabetes groups were established. At 21 days after cel transplantation, levels of glucose, triglyceride and insulin in the tail vein were detected. Additional y, morphological observations of kidney and pancreatic tissues were performed. RESULTS AND CONCLUSION:The levels of blood sugar, insulin and triglycerides in the diabetes group were significantly higher than those of the control group (P<0.05). Blood glucose and insulin levels in the stem cel transplantation group were significantly lower than those of the diabetes group (P<0.05). In addition, mesangial area and glomerular volume in the stem cel transplantation group were significantly lower compared with the diabetes group (P<0.05). These results confirm that bone marrow mesenchymal stem cel transplantation can reduce levels of blood glucose and serum insulin, contributing to the repair of damaged pancreas and kidney.

Objective:To evaluate the effects of different pneumoperitoneums used in laparoscopy on the growth of human cervical carcinoma cells in vitro.Methods:Human cervical carcinoma cell line(CaSki)were cultured in vitro and then exposed to pneumoperitoneums of pure carbon dioxide or pure nitrogen gas with the untreated group as control. The cell growth was determined by MTT assay,flow cytometry and electron microscopy. Results:Carbon dioxide stimulated the cell growth from 48h to 120h after treatment. For nitrogen gas group,there was a transient descent of cell proliferation from 48h to 72h after treatment. The tumor cells of carbon dioxide group in G2-M phases significantly increased. Active karyokinesis was observed in carbon dioxide group while slight mitochondrion swelling was observed in nitrogen gas group with the nucleus space expanded. Conclusions:Carbon dioxide pneumoperitoneum could increase the growth of human cervical carcinoma cells in vitro whereas nitrogen gas pneumoperitoneum had inhibiting effect on the cell growth.
