Objective To compare plasma concentrations of biomarkers of endothelial dysfunction between patients with primary aldosteronism (PA) and essential hypertension (EH),and to determine whether elevated levels of these biomarkers could predict development of early organ damage .Methods 56 PA patients ( the observation group) and 56 EH patients(the control group) matched for age,sex,blood pressure and duration of hypertension were included in this study .The plasma levels of biomarkers reflecting endothelial dysfunction [ von Willebrand factor (vWF),soluble intercellular adhesion molecule 1(sICAM-1),oxidized low density lipoprotein(ox-LDL)]were detec-ted and compared between PA and EH patients .The left ventricular mass index ( LVMI) determined by echocardio-graphy,24-hour urinary protein quantitative determination and urinary albumin excretion rate ( UAER) were analyzed to evaluate early organ damage .Results ( 1 ) In the observation group , the plasma markers of endothelial damage vWF (133.4 ±54.9)%,sICAM-1 (412.1 ±75.2)μg/L and ox-LDL (13.7 ±9.0) U/L levels were higher than those in the control group(t=4.642,3.955,2.843,all P<0.05),and the observation group had a higher 24 h urina-ry protein(t=2.042,P<0.05) and LVMI(t=7.235,P<0.05).(2)Correlation analysis showed that LVMI was positively correlated with PAC,ox-LDL,vWF (r=0.447,0.385,0.393,P=0.020,0.046,0.029),and was nega-tively correlated with admission blood K +(r=-0.294,P<0.05).UAER was positively correlated with PAC,vWF and sICAM-1 (r=0.622,0.389,0.499,all P<0.05),and was negatively correlated with admission blood K +(r=-0.314,P<0.05).Conclusion Patients with PA have severer endothelial dysfunction reflected by multiple bio-markers and earlier organ damage than patients with EH ,and plasma aldosterone concentration and multiple endotheli-al dysfunction biomarkers could independently predict early organ damage .

Objective To investigate the influence of Ondansetron on postoperative nausea and vomiting(PONV)in patient undergoing laparoscopic cholecystectomy with general anesthesia and the nursins care. Methods Ninety patients undergoing laparoscopic cholecystectomy with general anesthesia were randomly divided into 3 groups(n=30):low-dose Ondansetron group(O1 group)received 4 mg Ondansetron before section,high-dose Ondansetron group(O2 group)received 8 mg Ondansetron before section and the control group(C group)received normal saline.All injections were diluted to 4 ml.The number and degree of nausea and vomiting wag recorded during 24 h after operation.Results Number of patients with PONV in O1 group and O2 group were less than that of C group,P＜0.05,so was the PONV degree.No statistical difference was seen between O1 group and O2 group.Conclusion Intravenous injection of Ondansetron during operation can decrease the PONV in patient undergoing laparoscopic cholecystectomy with general anesthesia.

Objective To detect serum concentration of folate receptor alpha and to investigate its significance in the clinical application of patients with endometrial carcinoma. Methods Thirty-seven patients with endometrial carcinoma, 33 patients with endometrial hyperplasia and 10 healthy women were enrolled in this study. Sera were used to detect the the folate receptor alpha using an Enzyme-linked Immunosorbent Assay (ELISA) technique.The expression level of serum folate receptor alpha in different groups was analyzed. The correlation between the expression level of serum folate receptor alpha and age of patients, menopause, tumor morphology, myometrial invasion and clinical stage was was also analyzed in patients with endometrial carcinoma. Results Level of folate receptor alpha was successfully detected in serum of healthy women and patients with endometrial diseases. Level of folate receptor alpha in patients with endometrial carcinoma was much higher than that in patients with endometrial hyperplasia. Level of folate receptor alpha in patients with endometrial hyperplasia was also higher than that in the healthy controls, with significant difference (P < 0.05). In the endometrial carcinoma group,the levle of folate receptor alpha in serum was correlated with the clinical stage and myometrial invasion (P < 0.05), however, Level of folate receptor alpha was not correlated with the age of patients, menopause andtumor morphology(P > 0.05). Conclusion The Serum level of folate receptor alpha can be detected, and its expression will contribute to the diagnosis, treatment and predicting the prognosis of patients with endometrial carcinoma.

The effects of Amrinone (AMR)on left ventricular function in 30 cases of congestive heart failure patients was assessed by M-mode and pulsed Doppler echocardiography. AMR improves the systolic and diastolic function of left ventricle during and after 10 min (AMR lmg ? kg-1, infusion ). The mean stroke volume increased 20% and 18% ; cardiac output increased 23% , 19% ; cardiac index increased 23% and 23% ; ejection fraction increased 32% , 30%; mVcf increased 50% and 48% ; filling velocity in early diastole increased 30% and 21 %; respectively. There were no significant differently between during and after AMR infusion, but there were signifcantly difference a-mong before, during and after AMR infusion. The heart rate changed slightly without statistic significance. The results suggest that AMR could improve the systolic and diastolic function of left ventricle in congestive heart failure patients.

Objective To investigate the effect of maternal exposure to bisphenol A(BPA) via drinking water on body weight of immature offspring during pregnancy and lactation. Methods The pregnant female ICR mice were exposed to BPA groups(2. 282 9,22. 829 0,228. 290 0 μg/L) by drinking water from gestational day(GD)0 till postnatal day (PND)21,water and dimethyl sulfoxide(0. 01%) were served as blank and vehicle control. Maternal body weight was recorded every three days during pregnancy. Weight of pups per litter was measured every three days during lactation. Body weight of offspring was taken notes every week till PND 42 after delactation. ResultsThere was no significant difference in pregnant maternal body weight, average numbers and body weight of pups per litter preweaning among all groups. The offspring weight of the high-dose group at PND 42 was increased compared with control groups(P<0.05). The weight of female offspring was not significantly different among all groups at PND 28~42. The male offspring weight of the middle/high group at PND 35 and all groups at PND 42 significantly was elevated(P<0.05,P<0.01),and the high group was most significant. Conclusion Body weight of immature offspring is affected,especially male offspring after delectation by pregnant and lactational BPA exposure.
