Immune thrombocytopenia (ITP), the most common hemorrhagic disease, is an organ-specific autoimmune disease characterized by decreased platelets count due to auto-antibodies mediating platelets destruction and insufficient platelets production. The etiology of ITP is still not completely known. Regulatory T cells, also called Tregs, are character-ized by CD4+CD25+, and positive of transcription factor forkhead box P3. They belong to a subpopulation of T cells special-ized for immune regulation and play an important role in maintaining the immune balance. Decreased production and defect-ed function of CD4+CD25+Treg was found not only in the ITP animal model but also in the ITP patients. It indicates that the Treg was involved in the pathology of ITP. This review focus on the characteristic and function of Tregs and their relationship with pathogenesis of ITP.

Objective: To observe the synergetic effect of folic acid and genistein on apoptosis in the early stage of neuron and its possible mechanism. Methods: Cyclophosphamide was added to primary cultured neurons to induce apoptosis. Three different dosages of folic acid and genistein were used to inhibit apoptosis. The results were observed by flow cytometry and scanning electron microscopy (SEM). Results: 1.Folic acid and genistein might play a role in early stages of neuron apoptosis, and the synergetic effect was demonstrated when folic acid and genistein were administered together. 2. The membrane changes in early stages of neuron apoptosis observed by scanning electron microscope were also in agreement with the flow cytometry data. Conclusion: Genistein might reinforce the protective effect of folic acid on neural tube defects by restraining the apoptosis of the early stage of neuron.

This study was aimed to evaluate the applicability of common Chinese word segmentation software used in the literature study of traditional Chinese medicine (TCM) text,in order to put forward ideas on developing specialized TCM text word segmentation software.By means of installing and operating Chinese word segmentation software,the text segmentation experiment was conducted on TCM text samples.Aspects,such Chinese word segmentation accuracy,speed,maneuverability,reliability,extendibility,portability and other characteristics,were compared among different Chinese word segmentation software.The results showed that there were differences on the accuracy,speed,maneuverability,reliability,extendibility,portability among different Chinese word segmentation software.It was difficult to achieve best performance on different aspects by single software.Through the comparison of different Chinese word segmentation software,the Pan-Gu Segment software showed the best performance on accuracy,with good maneuverability,and high word segmentation efficiency,which was the most suitable for word segmentation in TCM text.It was concluded that developing specialized TCM text segmentation software may be the best solution to meet the requirement of text segmentation in TCM literature study.Basic studies should be strengthened from aspects,such as the construction of standard TCM copus,the completion of TCM dictionary base,the introduction,optimization and innovation of word segmentation algorithm,as well as the development of word segmentation software for TCM text.

Objective To investigate the relationship between H-type hypertension and unstable angina (UA).Methods Totally 147 elderly inpatients with hypertension and angina in our hospital were selected.Patients were divided into H-type hypertension group [n=72,serum homocysteine (Hcy) level ≥10 μmol/L] and primary hypertension group [n=75,serum homocysteine (Hcy) level ＜10 μmol/L].All patients underwent coronary angiography.Serum Hcy level was measured by enzyme method and compared between groups.Results There were statistical differences in the UA incidence,Gensini's score and high sensitive C-reactive protein (hsCRP) level between the H-type hypertension group and primary hypertension group [(44.4％ (32/72) vs.12.0％ (9/75),(44.2± 21.3) vs.(31.9±18.4),(4.3±2.1) μg/L vs.(2.0±1.9) μg/L,respectively,all P＜0.01].Serum Hcy level in H-type hypertension group was higher during UA attack than during UA remission [(22.2±7.1)μmol/L vs.(13.7±3.7)μmol/L,P＜ 0.01].Serum Hcy level during UA attack was increased in H-type hypertension group than in stable angina group [(22.2±7.1)μmol/L vs.(12.0± 4.2) μmol/L,P ＜ 0.01].Serum levels of Hcy,total cholesterol and low density lipoprotein cholesterol in primary hypertension group were higher in UA patients than in stable angina patients [(8.9±2.2)μmol/L vs.(6.6± 1.2)μmol/L,(6.9±0.7)mmol/L vs.(4.5±0.5)mmol/L,(4.6±0.8)mmol/L vs.(2.7 ± 0.6) mmol/L,respectively,P＜ 0.01 or P＜0.05].Logistic regression analysis showed that H-type hypertension was the independent risk factor for unstable angina in the elderly (OR =5.691,P ＜ 0.01).Conclusions H-type hypertension is closely correlated with unstable angina,which is the independent risk factor for unstable angina in the elderly.Serum Hcy level has significant correlation with coronary atherosclerotic plaque stability and the severity of coronary artery disease.

Objective To investigate the risk factors of in-stent restenosis (ISR) after coronary implantation of drug-eluting stent Methods One hundred and fifty-seven patients including 118 males and 39 females,who underwent successful implantation of drug-eluting stent, were recruited in the study. The patients were divided into the restenosis group (33 patients) and non-restenosis group ( 124 patients) according to the angiographic results. The associations of ISR with clinical and coronary angiographic characteristics were analyzed using univiriate analysis and logistic regression. Results In the restenosis group,there were 18 cases of diabetes mellitus ( 54. 5% ), 26 cases of frequency angina ( 78. 8% ), which were significantly higher than those of 31 cases of diabetes (25.0%) and 72 case of frequent angina (58. 1% ) in the non-restenosis group (χ2 = 10. 60, P ＜ 0. 01, χ2 = 4. 77, P = 0. 03 for diabetes mellitus and frequent angina, respectively). Compared to non-restenosis group, the occurrence rates of chronic total occasion, bifurcatus lesions, diffuse lesions were significandy higher in the restenosis group ( 19. 3% vs 7. 6% χ2 =5.92,21.1% vs 10. 2% χ2 =4. 34,26. 3%vs 12. 1% χ2 =6. 32,Ps ＜0. 05). Fifty-seven stents were implanted into the restenosis group,and one hundred and fifty-seven into the non-restenosis group. Logistic regression analysis showed that diabetes, frequent angina,chronic total occlusion lesions, bifurcatus lesions, diffuse lesions, stent length and diameter were significantly associated with restenosis ( OR value were 3.52,2. 59,3.05,3. 14,3.08,0. 93,95% CI were 1.56 - 7.90,1.02 - 6. 59,1.11 - 8. 36,1.30 - 7.59,1.34 - 7.05,0. 88 - 0. 98 respectively, Ps ＜ 0. 05 ). Conclusion After implantation of drug-eluting stent, diabetes mellitus, chronic total occasion lesions, frequent angina, diffuse lesions, bifurcatus lesions and stent length and diameter are associated with follow-up restenosis.

Objective To observe the effects of stellate ganglion block (SGB) on humoral immunity func-tion in patients who received modified radical mastectory (MRM). Methods Eigty female patients were randomly divided into control group(group Ⅰ ,n =40) and intervention group (group Ⅱ,n =40).
