Pulmonary arterial hypertension (PAH) is an incurable fatal disease, with the mechanism of imbalance of vascular contraction and relaxation which start as a series of pathophysiological reactions. Angiotensin-converting enzyme 2-angiotensin (1-7)-G protein-coupled receptor axis [ACE2-Ang(1-7)-Mas], an expanded vascular axis which is considered as new axis of renin-angiotensin system (RAS) is a negative regulator of the classical angiotensin-converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ type 1 receptor axis (ACE-AngⅡ-AT1R), a contraction vessel, proliferation axis. A retrospective study concerning the pathophysiological mechanism of ACE2 in the treatment of PAH was done and found that ACE2-Ang-(1-7)-Mas axis could reduce PAH induced by monocrotaline (MCT) through declining the inflammatory cascade, improving endothelial dysfunction and regulating autonomic nerve, reduce PAH induced by hypoxia through inhibiting the proliferation of pulmonary artery smooth muscle cells and reduce PAH induced by congenital heart disease. Therefore, ACE2 may become a future drug of preventing and treating PAH.

OBJECTIVE To investigate the ?-lactamases producing rate in Haemophilus influenzae(HIN) and the antibiotics sensitivity,to guide the treatment of Haemophilus species infection.METHODS The strains from respiratory tract samples,were isolated and cultivated in chocolate cultures 2006 to 2007.Drug sensitivity test and beta-lactam enzyme test of Haemophilus species were taken.The results were analyzed by software SPSS11.5.RESULTS Totally 195 isolates of HIN were isolated 32 produced ?-lactamases(16.4%).The sensitivity of H.influenzae to cefuroxime,cefotaxime and ampicillin/sulbactam was 90.8%,93.8% and 95.4%,respectively.CONCLUSIONS Cefotaxime,ampicillin/sulbactam and cefuroxime are the most effective antibiotics for H.influenzae infection.

OBJECTIVE:To explore optimal regime and less ADR for lupus nephritis(LN) by adopting self-made TCM prescription.METHODS:109 LN patients were assigned into control group(n=48) and therapy group(n=61).Both groups were treated with metacortandracin and cyclophosphamide.Control group were additionally given self-made TCM prescription.The clinical efficacy and adverse drug reaction(ADR) of 2 groups were compared.RESULTS:The curative rate and total response rate of therapy group were 77.05%(47/61) and 95.08%(58/61) respectively and those of control group 58.33%(28/48) and 77.08%(37/48).The curative rate and total response rate of therapy group were all higher than those of control group.There were significant difference between 2 groups(P

Objective To investigate the serum lipoprotein (Lp) (a) level in patients with acute ischemic stroke and the prediction for short-term functional outcome. Methods The levels of serum Lp(a) were measured in 210 patients with acute ischemic stroke (within 24 h after onset) and 100 healthy people matched the gender and age. The patients were assessed with National Institutes of Health Stroke Scale (NIHSS) as admission, and modified Rankin Scale (mRS) as discharge. Results The median of Lp(a) was 325 mg/L (IQR: 180~545) in patients,significantly more than 148 mg/L (IQR: 69~265) in the normal controls (P<0.001). Level of serum Lp(a) was an independent variable for functional outcome (OR=1.004, 95%CI: 1.001~1.007, P<0.001) and death (OR=1.006, 95%CI: 1.001~1.008, P<0.001) in patients. In the receiver operating characteristic curve, the area under curve was more in the combined model [Lp(a) and NIHSS] than the NIHSS alone.Conclusion Serum Lp(a) increased in the in patients with acute ischemic stroke, and may predict the short-term outcome independently.

Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

OBJECTIVE To study the distribution and the drug resistance of fungus species in hospital in one year,and to provide the evidence for clinical treatment.METHODS The fungus isolations were detected by colored separated-cuture,API 20C AUX,VITEK-60 identification system,and YBC identification card.The drug sensitivity was detected by ATB Fungus 3 INT strip.RESULTS Of the 96 islatens,37.5% were Candida glabrata,30.2% C.albicans and 27.1% were C.tropicalis.All the tested isolates were sensitive to 5-flucytosine(5Fc) and amphotericinB(AMB).CONCLUSIONS The hospital fungal infection of urinary system is caused by C.glabrata,C.albicans and C.tropicalis mostly.The clinical treatment should base on the drug sensitivity results.

Through the Introduction of the visualization technology based on VREL and its application in ultrasound teaching,the teaching means has been changed,the teaching content enriched and the contact between basic and clinic knowledge enhanced,which indicates that the visualization technology exerts an important role in ultrasound teaching.

Objective To investigate the mechanisms of mesenchymal stromal cells (MSCs) in promoting the transplanted islets neovascularization.Methods We performed co-transplantation of allogeneic islet and MSCs into non-obese diabetic (NOD) mice and the lymphocyte chimeric rate was detected by flow cytometry.The MSCs migration,transformation and secretion of cytokines were detected by immunofluorescence.Results In mice of co-combination transplantation of islet with MSCs,donor lymphocytic chimerism in graft was increased.BM-MSCs can migrate to transplanted islet,differentiate into vascular smooth muscle cells,and also secrete vascular endothelial growth factor (VEGF).Conclusions MSCs can migrate to transplanted islet and promote neovascularization.Also,it enhanced allograft immune tolerance of islet grafts via increasing donor lymphocytic chimerism.
