Objective To study effect of drug treatment in polycystic ovary syndrome patients with hyperprolactinemia.Methods We retrospectively studied 50 women with polycystic ovary syndrome and hyperprolactinemia from the outpatient between January 2005 and April 2008.Acccording to the beginning time of bmmocriptine.all women were divided into two groups.Groups Ⅰ was composed of 38 cases who received bromocriptine before induction of ovulation cycies,and the dose of bromocriptine was modulated depending on the level of serum prolaotin.When serum prolactin was controlled at normal levels,we decreased the dosage of bromocriptine step by step(1.25mg once),and then continued the treatment at maintenance dosage for no less than 3 weeks.After a baseline ultrasonographic examination on day 3,patients were treated with clomiphene citrate at a dosage of 100mg(2 tablets/day)for 5 days of a normal cycle or progesterone-induced bleeding.On day 9.we monitored the growth conditions of follicles routinely with trails-vagihal ultrasound.If there was no dominant follicle,we added human menopausal hormone(HMG 75U/d)to the protocol.Human chorionic gonadotropin(HCG,5 000-10 000IU)was given intramuscularly when the mean diameter of a follicle reached at least 18mm.At the same time we iustmcted the patients to have sexual intercourses or carried out artificial inseminations before and after ovulation.Group Ⅱ were 12 cases in which induction of ovulations were commenced almost simultaneously with beginning of bromeoriptine.The same protucol was given to patients in group Ⅱ.The procedures of ovulation induction and the outcomes of treatment were analyzed and compared.Results Compared with groupⅡ.the days of using HMG in group Ⅰ was shorter by instructing the time of sexual intercourse.The difference was significant(P=0.004).And there were similar rosults in the artificial insemination cycles(P=0.009).The rate of pregnancy in group Ⅰ(42% 16/38)was higher than that in group Ⅱ(25%,3/12),but the difference was not obvious.Conclusion Bromocriptine administration before the stimulated ovulation therapy can decrease the total dosage and treatment course of ovulating drugs.Induction of ovulations simultaneously with start of bromocriptine therapy can shorten the treatment time of infertility.

While in control group, 17 (56.67%) cases were cured, 5 (16.67%) cases were obviously improved, 8 (26.67%) cases were improved. There was significant difference between these two groups (P<0.05). The time of treatment was less in the electroacupuncture group than in the control (P<0.05). Conclusion Electroacupuncture is effective on migraine.

Nitric oxide is an important signalling and effector molecule which plays an indispensable role in modulating the function of platelets.Recent research revealed that a L-arginine/nitric oxide pathway presented in human platelets and nitric oxide derived from this pathway was called platelet-derived nitric oxide.The impaired synthesis and release of platelet-derived nitric oxide is closely related to the onset and development of some cardiovascular diseases,such as hypertension,atherosclerosis and diabetes.Recent progress in the relationship between platelet-derived nitric oxide and some cardiovascular diseases is reviewed in this article.Thorough research in PDNO not only has great clinical significance but also contributes to finding new ideas and new target for drug therapy.

Objective To investigate the influencing factors for the short-term prognosis in elderly patients with posterior circulation infarction after intravenous thrombolysis.Methods We retrospectively analyzed the clinical data of 67 elderly patients with posterior circulation infarction treated with thrombolysis from March 2011 to December 2012.Clinical data of age,sex,hypertension,hyperlipidemia,glucose abnormalities,and thrombolysis,National Institute of Health stroke scale (NIHSS) score on admission,hyperhomocystinemia,the infarction area,anticoagulation and antiplatelet treatment were collected.All patients were followed up after discharge.The prognosis was assessed by the Rankin scale (mRS) after 3 months of thrombolysis.Patients were divided into good (MRS score ≤2) prognosis group and poor (mRS＞2) prognosis group.Results There were 43 cases (64.2％) in good prognosis group and 24 cases (35.8％) in poor prognosis group.Logistic regression analysis showed that NIHSS score＞12 (95％CI:1.087-1.569,P=0.005),thrombolysis time＞4.5 h (95％CI:1.362-2.258,P=0.004),high homocysteine levels (95％CI:0.612-0.956,P =0.000),platelet after 24 h (95％ CI:0.785 1.133,P=0.001) were the independent risk factors for the poor prognosis of posterior circulation infarction in elderly patients after intravenous thrombolysis.Conclusions Early thrombolysis and timely anticoagulant treatments have certain significances in improving the short-term prognosis in patients with posterior circulation infarction.

Objective To investigate the prognostic value of regulatory B cells (Bregs) in patients with acute pancreatitis .Methods Flow cytometry analysis was performed to detected the percentages of CD19+IL-10+and CD19+CD24hiCD27hi Bregs in peripheral blood samples collected from patients with acute pancreatitis (36 cases with mild acute pancreatitis and 15 cases with severe acute pancreatitis ) as well as the surface costimulatory molecules including CD80 and CD86 on CD19+CD24hiCD27hi Bregs.Their correlations with lymphocytes and C-reactive protein ( CRP) were further analyzed .Results The numbers of lympho-cytes, CD19+lymphocytes, CD19+IL-10+and CD19+CD24hi CD27hi Bregs in peripheral blood samples col-lected from patients with severe and mild acute pancreatitis as well as the mean fluorescence intensities ( MFI) of CD80 and CD86 were significantly lower than those from healthy subjects .Compared with patients with mild acute pancreatitis , the numbers of lymphocytes and CD 19+lymphocytes , the absolute numbers of CD19+IL-10+and CD19+CD24hiCD27hi Bregs as well as the mean fluorescence intensities (MFI) of CD80 and CD86 in patients with severe acute pancreatitis were significantly decreased .The percentages of CD19+IL-10+and CD19+CD24hiCD27hi Bregs in patients with mild acute pancreatitis were significantly increased af-ter an initial drop , but in patients with severe acute pancreatitis those values were continuously decreased along with the disease progression .The percentage of CD19+IL-10+Bregs was positively correlated with the percentage of CD19+CD24hiCD27hi Bregs and the absolute number of CD19+lymphocytes, but was negatively correlated with CRP .Conclusion The abnormal number and function of CD 19+IL-10+and CD19+CD24 hi CD27hi Bregs might be one of the important reasons causing immune dysfunction in patients with acute pan -creatitis.

Endothelial progenitor cells (EPCs) are a kind of progenitor cells with high potential of proliferation, which exist in the bone marrow, umbilical cord blood, and peripheral blood. Under certain conditions, EPCs can differentiate into mature vascular endothelial cells. Many studies have shown that EPCs could delay the onset and development of atherosclerosis by promoting the repair of the endothelium and neovascularization. EPCs have also been considered to be a biological marker for cardiovascular diseases. Recent investigations demonstrate that EPCs can mediate the effect of some anti-atherosclerosis drugs. This paper reviews the role of EPCs in atherosclerosis and the influence of drugs on EPC function. The feasibility and the problem of using EPCs as a treatment strategy are also discussed.

OBJECTIVETo investigate the protective effects of exendin-4 on vascular endothelial cells and explore the possible mechanism.

METHODSHuman umbilical vascular endothelial cells (HUVECs) were cultured in the presence of high glucose and tumor necrosis factor-α (TNF-α, 10 ng/ml) with or without exendin-4. The level of nitric oxide (NO) in the cell culture supernatant was measured using a nitrate reductase method. The expression of intercellular adhesion molecule-1 (ICAM-1) mRNA was measured by real-time PCR, and nuclear factor-κB (NF-κB) p65 translocation was detected using immunofluorescence assay. Western blotting was employed to measure the expression of p38 MAPK protein in the treated cells.

RESULTSIn the presence of high glucose and TNF-α, treatment of cells with exendin-4 did not obviously affect the cellular synthesis of NO, but significantly down-regulated the expression of ICAM-1 mRNA (P<0.01). The nuclear fluorescence intensity of NF-κB p65 and the expression level of p38 MAPK protein in the cells were significantly lowered by exendin-4 treatment (P<0.01).

CONCLUSIONExendin-4 ameliorates high glucose- and TNF-α-induced HUVEC-12 cell damage by inhibiting the expression of p38 MAPK protein and translocation of NF-κB p65.
