Objective To compare effect of ticagrelor and clopidogrel on bleeding in elderly patients after stenting.Methods 48 elderly patients after stenting who were diagnosed with acute coronary syndrome in the hospital were collected.All patients were divided into clopidogrel group and ticagrelor group according to different therapy, 24 cases in each group,and were given corresponding drug treatment in each group.After treatment, the platelet inhibition rate, cardiovascular events and bleeding events were observed.Results After treatment, compared with clopidogrel group, the platelet inhibition rate was higher in ticagrelor group(P<0.05), the incidence of cardiovascular events was lower in ticagrelor group (4.16%vs.25.00%;P<0.05), but there was no obvious difference in incidence of bleeding events of ticagrelor group (4.16% vs.8.32%).Conclusion In elderly patients after stent implantation, ticagrelor could inhibit platelet aggregation better than clopidogrel, prevent the occurrence of cardiovascular events, and would not increase the risk of bleeding.

Objective To observe the expression of P2X receptors in the hippocampus of telomerase gene knockout mice after acupuncturing the bilateral ST36 acupoints.Methods Eighteen telomerase gene knockout homozygous mice were randomly divided into a blank control group (group A),a manual acupuncture group (group B) and an electric acupuncture group (group C),each of 6.Group A was not given any intervention,while groups B and C were provided with manual or electric acupuncture at point ST36 for 7 days.The expression of P2X receptors and cAMP response element bound protein (CREB) in the hippocampus were observed and compared among the 3 groups.Results The expression of P2X4 in the hippocampus was not significantly different among the 3 groups in groups B and C decreased significantly compared with group A,but there were no significant differences between group Bs and C.The expression of CREB in group C decreased significantly compared with groups A and B.Conclusion EA inhibits the expression of P2X4 receptor and CREB the hippocampus.The signaling pathway may play an important role in the mechanism of action of acupuncture in neurodegenerative diseases.

Objective To investigate the expression of FSCN1 mRNA in breast carcinoma and benign breast diseases and its relationship to clinicopathological characteristics of breast cancer. Methods Sixty-three cases of breast cancer and thirty cases of benign breast diseases were analyzed by in situ hybridization. Results The expression rates of FSCN1 mRNA in breast cancer tissue and benign breast lesions were 65.1% and 90.0% , respectively (P < 0.05). No relation was found between the expression of FSCN1 mRNA and histopathologic grading, ER, PR, karyokinesis figure, patients′ age, tumor size, lymph node metastasis, TNM stage and c-erbB-2 expression in breast cancer. Survival rates of breast cancer patients with carcinoma expressing FSCN1 mRNA were 92.3% , while those patients with tumors which was negative for FSCN1 mRNA were 82.2%, but there was no significance difference. A significant correlation was observed between FSCN1 mRNA and its protein expression (rs = 0.315, P < 0.05). Conclusion FSCN1 is downregulated in breast carcinoma which may be associated with breast carcinogenesis.

Objective To investigate the expression of p53,VEGF,E-cad,CK20 and its clinical meanings in bladder transitional cell carcinoma. Methods The specimen microarrays and immunohistochemistry were applied to detect selected cancer-related protein expression in 45 cases of bladder TCC and 8 cases of normal control. Results Abnormal expression of p53,E-cad and CK20 were detected 100.0%,55.6%,55.6% respectively in bladder TCC group,which were expressed normally in control group with significant differences.However,there was no VEGF expression differences between those 2 groups (87.5% v.86.7%).Abnormal expression intensity of p53 and expression rate of E-cad were closely related to the pathological features.CK20 expression was co-related positively with disease staging rather than grading.VEGF played less role in co-relating with pathological features. Conclusions p53,E-cad and CK20 play an important roles in the development of bladder TCC,and VEGF plays less.Microarrays is suggested to detect a large scale of specimen for multiple proteins,it is effective.

Objective To investigate the clinical efficacy of drug-eluting stent( DES) combined with clopi-dogrel therapy in patients with coronary heart disease. Methods 123 patients underwent percutaneous coronary intervention (PCI) were randomly divided into observation group (DES) of 60 cases and the control group ( bare-metal stent,BMS) of 63 cases. The observation group was given the treatment of DES combined clopidogrel, the control group was given the treatment of BMS combined clopidogrel. The stent implantation and the follow-up two-year MACE were observed. Results (1) The average implanted stent length of the observation group was longer than that of the control group(P<(0.05) ,the angiography in vascular disease and complexity between the two groups had no significant difference ( P > 0. 05 ) ; the success rate of surgery in the two groups was 100% , after operation the TIMI flow reached grade 3. (2) The incidence of angina pectoris and revascularization rate of the observation group was significantly lower than that of the control group (P < 0.05); the rate of coronary angiography, recurrent myocardial infarction and the incidence of cardiac death between the two groups had no significant difference ( P > 0.05). Conclusion DES combined with clopidogrel maintenance therapy for a year in patients with coronary heart disease had a good long-term efficacy.

Objective:To study dynamic change of brain natriuretic peptide (BNP),left ventricular ejection fraction (LVEF)and prognosis improvement in patients with acute anterior myocardial infarction (AAMI)complicated hy-poxemia after noninvasive mechanical ventilation therapy.Methods:A total of 60 patients with AAMI complicated hypoxemia,who were hospitalized in our hospital from Mar 2011 to Oct 2013,were divided into noninvasive venti-lation group (n=28)and routine treatment group (n=32)according to number table.Dynamic change of BNP, LVEF and prognosis were observed and compared between two groups.Results:After treatment,BNP level and LVEF significantly improved in both groups (P<0.05 all),compared with routine treatment group,there was more significant reduction in BNP level [24h:(263.6±23.3)μmol/L vs.(126.2±21.9)μmol/L]and significant rise in LVEF [(40.6±13.1)% vs.(47.3±14.7)%]in noninvasive ventilation group after treatment (P<0.01 both);af-ter 30d follow-up,there were significant rise in 6min walking distance (percentage of 426~550m,59.3% vs. 75.0%),LVEF [(41.1±11.7)% vs.(49.4±12.5)%]and survival rate (90.6% vs.96.4%),and significant re-duction in rehospitalization rate (12.5% vs.7.1%)in noninvasive ventilation group,P<0.01 all.Conclusion:Ear-ly noninvasive mechanical ventilation therapy can significantly improve cardiac function,exercise tolerance and short-term prognosis in patients with acute anterior myocardial infarction complicated hypoxemia.

Purpose To explore the biological significance of BCL-6 and ZEB2 in invasion,metastasis and prognosis of breast cancer.Methods The expressions of BCL-6,ZEB2 protein and mRNA were detected respectively in 228 cases of breast cancer and 80 cases of breast benign lesions by immunohistochemical SP two-step staining and situ hybridization.Result The expression levels of BCL-6,ZEB2 protein and mRNA in breast cancer tissues were significantly higher than in breast benign lesions (P ＜ 0.05).The expressions of BCL-6 was positively correlated with tumor size,lymphatic metastasis,histological grade,TNM staging and HER-2 expression (P ＜ 0.05).The expressions of ZEB2 was positively correlated with tumor size,lymphatic metastasis,TNM staging and HER-2 expression (P ＜ 0.05).The overall survival and relapse-free survival of BCL-6 and ZEB2 positive expression were significantly less than the negative expression (P ＜ 0.01).Conclusion The BCL-6 and ZEB2 are closely correlated with the evolution process of breast cancer,which may become important means for monitoring and warning the metastasis,invasion,and prognosis of breast cancer.

Objective To study the immunoregulatory effects of bone marrow mesenchymal stem cells (MSC) on allogeneic peripheral B lymphocytes in vitro. Methods MSCs were isolated and cultured from bone marrow by gradient centrifugation. Mononuclear cells were isolated routinely from peripheral blood, then monocytes were eliminated by L-leucine methy ester method. Remained T lymphocytes were eliminated by AET-SRBC rosette method. The action of MSCs and its supernatant on B lymphocytes proliferation in the presence of anti-human IgM goat antibodies (anti-IgM) was investigated by MTT. The IgG, IgM in the supernatant were detected by ELISA. The percent of apoptosis B lymphocytes, co-cultured with MSCs for 24 or 48h, was assayed by FACS. Results MSCs and its supernatant inhibited B lymphocytes proliferation and Ig secretion. The inhibitory effect depended on the amount of MSCs and condition of its supernatant. The date of FACS indicated that the apoptosis ratio of B lymphocytes, co-cultured with MSCs for different times, were non-significant. The inhibitory effect of MSCs on B lymphocytes was temporary and reversible. Conclusion MSCs have immunoregulatory effects on B lymphocytes, and its mechanisms are complex, not only correlating with the concentration of MSCs but also the action between cells and the secretory cytokine of MSCs.
