More and more research proved that CD4+CD25+ regulatory T cells (Treg cells) play an important role in immune tolerance in these years. Known as a T cell growth factor, Interleukin2 (IL-2) regulated the immune tolerance induced by Treg cells. IL-2 sustained the activity of Treg cells both in thymus and periphery while it was dispensable for the development of Treg cells in thymus. In addition, IL-2 signal affected the function of Treg cells and maintained their competitive fitness. Therefore, CD4+CD25+ Treg cells and IL-2 formed an immune network to regulate the processes of immune response, immune tolerance and autoimmune homeostasis.

Diarrhoea is one of the main causes of morbidity and mortality in the developing countries,it accounts for a large part of global disease burden every year.Water and sanitation are closely associated with the morbidity of diarrhea.The recent researches were reviewed in this paper,and the effect of drinking water,sanitation and hygienic knowledge on diarrhea was discussed.The incidence rate of diarrhea was likely to decrease as water supply and sanitation were improved.

A satisfaction survey carried out by Beijing Chao-Yang Hospital during the Beijing 2008 Olympic Games, found differences of patient satisfaction between locals and overseas patients in consulting environment, outpatient procedure, quality of service, quality of diagnosis and treatment. The patient satisfaction of overseas patients was lower than locals. Especially noteworthy is the low satisfaction of the former for the hospital coloring, privacy in the sector, registration, vocal communication, patient condition statement, nurse attitude and service quality. Real-time improvement in these aspects of medical services has harvested obvious progress. Results of the satisfaction survey provided valuable reference materials for large-scale activities, and ongoing improvement of medical services in the long run.

Objective To investigate drug adverse reactions caused by Qingkailing injection,in order to provide a reference for clinical drug rational use.Method 2003-2008 Qingkailing Injection Case reports of adverse reactions collected from the Guizhou Province Monitoring Center Database was analysed descriptively.Result The occurrence of Qingkailing injection adverse reactions was not correlated to gender.The clinical manifestation was mainly for allergic reactions(305 cases,accounting for 35.59%)and systemic damage(417 cases,accounting for 48.66%).There were 652 cases adverse reactions occurred in 30min accounting for 76.08%.Conclusion Clinical physicians,pharmacists should attach importance to Qingkailing injection adverse reactions,persist in rational drug use and focus on the observation,after druguse.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

Objective To observe the expression of SGK in decidua in patients with unexplained recurrent spontaneous abortion(URSA) and to investigate its role in the course of apoptosis.Methods The expression of SGK was detected by immunohistochemistry in decidua of URSA(abortion group,n =50) and normal first trimester pregnant women(control group,n =30).The apoptotic index was detected by TUNEL.Results Compared with the control group,the positive expression of SGK decreased significantly in the abortion group,and the difference was statistically significant(x2 =6.78,P ＜ 0.05).The average apoptotic index of the abortion group was (8.19 ± 3.58) ％,which was significantly higher than (2.87 ±1.07)％ of the control group(t =7.94,P＜0.05).Conclusion Intensive apoptosis,the decreasing positive expression rate of SGK in decidua cells may play critical roles in URSA.

OBJECTIVE:To analyze the chemical compositions of the volatile oil on the overground parts of India wormwood herbs.METHODS:The chemical compositions of the volatile oil of the overground parts of India wormwood herbs extracted by wet distillation were analyzed by capillary GC-MS method and the relative component percentage of each component was determined by GC area normalization method.RESULTS:52peaks were separated by capillary GC-MS and their corresponding compounds were identified.The main chemical compositions were as follows:?—Caryophyllene(8.245%);10,10—Dimethyl—2,6—dimethylenebicyclo[7.2.0]undecane—5—?—alcohol.(7.089%);6,10,14—trimethyl—2—Pentadecanone(5.199%);Caryophyllene oxide(4.808%),etc.CONCLUSION:This study can be served as a scientific basis for the further exploitation and utilization of India wormwood herbs.

AIM and METHODS: To investigate expression of intercellular adhesion molecule-1(ICAM-1) on human umbilical vein endothelial cells (HUVEC) induced by lipopolysaccharide (LPS) , and inhibiting role of polydatin by cellular immune fluorescent staining and laser confocal microscope scanning technology. RESULTS: Compared with basic expression of ICAM-1 on HUVEC, the ICAM-1 expression was enhanced significantly after stimulated by LPS from 8 h to 36 h, dose-dependent relation appeared between expression of ICAM-1 and LPS. ICAM-1 expression on endothelial cells treated only by polydatin had no abvious change,but inducing role of LPS to expression of ICAM-1 was inhibited significantly by polydatin pretreating endothelial cells. CONCLUSION: The expression of ICAM-1 on endothelial cells can be promoted by LPS , and polydatin can inhibit LPS-induced ICAM-1 expression
