Objective To observe the clinical efficacy and adverse reactions of desogestrel ethinylestradiol in the treatment of dysfunctional uterine bleeding ( adolescent Dub ) .Methods 86 cases with adolescent functional bleeding were divided into the treatment group and control group ,43 cases in each group .The control group received conjugated estrogen(Premarin) treatment,the treatment group was given desogestrel ethinylestradiol treatment .The hemostatic effect and drug adverse reaction of the two groups were observed .Results The cure rate of the treatment group was 65.1%,that in the control group was 23.3%,there was significant difference between the two groups (χ2 =15.28,P<0.01).The hemostatic time of the treatment group was (33.24 ±12.85)h,which was shorter than (50.31 ± 16.32)h of the control group (t=5.39,P<0.05).The incidence rate of adverse reactions between the two groups had no significant difference (χ2 =0.49,P>0.05).Conclusion Desogestrel ethinylestradiol in the treatment of ado-lescent functional bleeding has exact curative effect ,it has low incidence of adverse reactions and better acceptance .

Objective To investigate the effects of substance P (SP) on the expression of apoptosis-associated genes in fibroblasts derived from pathological scars. Methods Fibroblasts derived from keloid, hypertrophic scar and normal skin were cultured separately in media containing SP and SP receptor antagonist. PCNA, bcl-2 and bax protein in fibroblasts were assessed by means of immunohistochemistry. Results SP enhanced PCNA and bcl-2 expression in all three kinds of fibroblasts, whereas, bax expression was inhibited significantly. SP inhibited the expression of bax in keloid scar fibroblasts (KSFB) more remarkably than that in hypertrophic scar fibroblasts (HSFB) or normal fibroblasts (NFB), and the effect was stronger on HSFB than on NFB. SP receptor antagonist could inhibit those effects of SP totally or partially. Conclusion SP may play an important role in the formation of pathological scars by modulating the expression of apoptosis-associated genes, which is mediated by SP receptor.

Objective To investigate the up regulation of captopril on the platelet nitric oxide(NO) synthase and clinical application in patients with ischemic stroke.Methods The washed platelets in vitro of the patients with acute ischemic stroke and healthy controls were added with oxidized LDL(oxLDL) and captopril followed by measurement of platelet NO synthase activity.Plasma oxLDL,NO sythase,NO and platelet NO sythase,NO in 40 patients were measured before oral captopril and after oral captropril 1 month,3 months.Results (1)After the washed platelets in vitro were added with oxLDL,the platelet NO synthase activities of the patients and controls were all significantly decreased( P

Objective: To observe changes of variation of red blood cell distribution width-coefficient (RDW-CV), levels of matrix metalloproteinase (MMP)-2, MMP-9 and tissue inhibitor of metalloproteinases (TIMP)-1 in patients with essential hypertension (EH) of different risk stratification.Methods: A total of 105 EH patients treated in our department from Oct 2015 to Sep 2016 were regarded as EH group.According to hypertension risk stratification, they were divided into low risk group (n=34), medium risk group (n=38) and high-and extremely high risk group (n=33).Another 105 subjects with corresponding age and gender were selected as healthy control group during the same period.RDW-CV, serum levels of MMP-2, MMP-9 and TIMP-1 were measured and compared among all groups.Multivariate Logistic regression analysis was used to analyze relationship among above indexes and hypertension.Results: Compared with healthy control group, there were significant rise in RDW-CV [(12.57±1.46) vs.(14.54±1.82)], serum levels of MMP-2 [(121.71±18.86)ng/ml vs.(155.43±40.81)ng/ml], MMP-9 [(109.72±21.80)ng/ml vs.(191.23±53.05)ng/ml] and TIMP-1 [(59.42±9.41)ng/ml vs.(83.64±15.82)ng/ml] in EH group, P<0.05 or <0.01.Compared with low risk group, there were significant rise in RDW-CV [(13.35±1.54) vs.(14.43±1.17) vs.(15.90±1.81)], serum levels of MMP-2 [(131.21±35.24) ng/ml vs.(152.16±33.15)ng/ml vs.(184.16±37.14)ng/ml], MMP-9 [(163.95±38.61) ng/ml vs.(198.70±43.52)ng/ml vs.(232.83±54.12)ng/ml] and TIMP-1 [(73.15±13.12)ng/ml vs.(83.78±10.22) ng/ml vs.(94.27±16.77)ng/ml] in medium risk group, high-and extremely high risk group, and those of high-and extremely high risk group were significantly higher than those of medium risk group, P<0.05 or <0.01.Multivariate Logistic regression analysis indicated that RDW-CV, MMP-2, MMP-9 and TIMP-1 were independent risk factors for hypertension (OR=2.248~2.725, P<0.05 or <0.01).Conclusion: RDW-CV,MMP-2,MMP-9 and TIMP-1 are independent risk factors for hypertension, active monitoring and intervention should be given for these risk factors.

Objective To express TmpA recombinant antigen of Treponema pallidum in E.coli and to develop an Enzyme linked Immunoassay (EIA) based on the recombinant antigen for diagnosing syphilis. Methods The target TmpA gene was amplified by polymerase chain reaction (PCR). The PCR products of the gene were inserted into pBluescript T vector, and then expressed in E.coli, using pQE 30 system. Then the recombinant antigen was purified by an affinity chromatography and used for the development of EIA. Results The antigenicity of the recombinant antigen was identified by western blotting (WB) and EIA. The sensitivity and specificity of EIA were 100%(10/10) and 100% (20/20), respectively. The positive rates of anti TmpA antibodies were 91.67% (11/12) for the patients with Ⅰ phase of syphilis and 100% for the patients of Ⅱ and late stage of the disease. Conclusions The TmpA recombinant protein can be used to diagnose syphilis since 97.2% (35/36) of patients with syphilis were positive for the anti TmpA antibody by EIA.

Objective To compare expression of extracellular proteins of virulent H37Rv and attenuated H37Ra in order to search differential proteins,to provide a train of thought for studing M.TB toxicity further.Methods Extracellular proteins were extracted from H37Rv and H37Ra which were inoculated and cultured on Suton's medium for three weeks.The first dimensional electrophoresis was performed on immobilized pH gradient rod gels(pH 3～10).Then the proteins in the rod gels were separated using SDS-PAGE gels.The silver-stained gels were dried and scanned with image scanner.The 2D image analysis was performed with image Master 2D Elite 3 10.Results The most protein spots deriving from extracellular proteins of H37Rv and H37Ra strains were in acidic range.In the basic range(pI more than 9 0),the number of protein spots belong to extracellular proteins of H37Rv and H37Ra was few.Three protein spots belong to low molecular range in H37Rv strain.However,absent in H37Ra strain.Conclusions Two-dimensional gel electrophoresis is useful to separate protein in Mycobacterium tuberculosis.

Objective To investigate the influence of brain natrluretic peptide(BNP) in the prognosis of cardiac surgery.Methods Selected 115 cases of pafients with the first cardiac surgery.Their BNP concentration was measured before operation. Observed the relationship between BNP and postoperative atrial fibrillation,mechanical ventilation time,hospital stay,and the mortality of 30 d.Results Whether the patients had hypertension,diabetes,myocardial infarction history,left main stem disease and hemoglobin level or not,showed no definite relationship with BNP (P>0.05).Preoperative lower left ventricular ejection fraction (LVEF)(P=0.002) and European system for cardiac operation risk evaluation [(5±3)scores](P=0.003) were associated with higher BNP level.Postoperative mechanical ventilation time was(15.0±5.4)h,hospital stay was (32±11) d,showed a clear relationship with BNP(P= 0.035,0.001),but postoperative mediastinal infection,atrial fibrillation and mortality of 30 d had no definite relationship with BNP(P>0.05).Conclusion BNP can be used to predict the risk after cardiac surgery.
