Objective To investigate the effects of Qiliqiangxin capsule on serum concentration of adiponectin (APN) and heart function in patients with uremia combined with heart failure. Methods Uremia patients combined with heart failure were randomly divided into treatment group and control group , both of which were given anti-failure routine therapy. The patients in treatment group were treated with Qiliqiangxin capsule for 8 weeks and those in control group with placebo. The New York Heart Association (NYHA) heart function classi-fication, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction(LVEF), and the levels of APN were observed before and after treatment. Results The level of APN in uremic patients combined with heart failure was significantly higher than that in normal subjects. With the increase in the class of NYHA heart function, the serum concentrations of APN increased, but the difference was not significant(P > 0.05). After 8 weeks′ treatment, the effective rate in treatment group was higher than that in control group (P < 0.05). LVEDD and LVESD in both groups decreased significantly. LVEF in both groups increased, but serum concentration of APN decreased significantly. More obvious effects were observed in treatment group (P < 0.05). Conclution Qiliqiangxin capsule could significantly reduce the level of APN and improve heart function in patients with uremia combined with heart failure.

OBJECTIVE:To establish a method for simultaneous determination of valsartan and hydrochlorothiazide in Valsar-tan hydrochlorothiazide tablets. METHODS:UPLC was adopted. The determination was performed on Phenomenex C18 column with mobile phase consisted of [0.1% phosphoric acid solution-acetonitrile(95 : 5,V/V)]-[0.1% phosphoric acid solution-acetonitrile (5 : 95,V/V)](gradient elution)at the flow rate of 0.25 mL/min. The detection wavelength was set at 272 nm,and the column tem-perature was 35 ℃. The sample size was 1.5 μL. RESULTS:The linear range were 8.1-324.2 μg/mL for valsartan(r=0.9999)and 1.2-50.1 μg/mL for hydrochlorothiazide(r=0.9999). The limits of quantitation were 0.24,0.04 ng,and the limits of detection were 0.06,0.01 ng. RSDs of precision,stability and reproducibility tests were less than 2.0%;recoveries were 97.69%-100.35%for valsartan(RSD=1.03%,n=9)and 98.27%-100.60% for hydrochlorothiazide(RSD=0.83%,n=9). CONCLUSIONS:The method is simple,rapid and accurate,and can be used for the simultaneous determination of valsartan and hydrochlorothiazide in Valsartan hydrochlorothiazide tablets.

Objective To investigate the efficacy of intracoronary tirofiban during percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Seventy-six consecutive AMI patients,treated with primary coronary angioplasty in 12 hours were enrolled.They were randomly divided into two groups:tirofiban group(39 cases)and control group(37 cases).Tirofiban group was treated with intracoronary timfiban during PCI and after the operation for 48 hours.Both of them were given heparin in PCI and aspirin,clopidogrel before PCI.At the end of PCI procedure,angiographic features such as TIMI flow grade and TIMI myocardial perfusion grade(TMPG)were analyzed.The difference of two groups in complication and major adverse cardiac events(MACE) was investigated.Results The myocardial reperfusion of tirofiban group was better than that of control group[TIMI grade 3 flow 94.9%(37/39) vs 78.4%(29/37),P<0.05;TMPG 3 grade 89.7%(35/39)vs 67.6%(25/37),P<0.05].There was no significant difference between two groups in bleeding complication.The occurrence of MACE in tirofiban group was less than that in control group[7.7%(3/39)vs 18.9%(7/37),P<0.05].Conclusion Intracoronary tirofiban dunng primary PCI in patients with AMI can improve coronary flow and myocardial perfusion,and has no more bleeding and less MACE occurrence.

Purpose To investigate the CT gemstone spectral imaging features of gastric stromal tumors (GST), so as to discuss the value of CT gemstone spectral imaging in the diagnosis and differential diagnosis of GST. Materials and Methods Thirty patients with GST proved pathologically were scanned by gemstone spectral imaging. Their GSI scanning image data and the related clinical data were retrospectively analyzed, and the quantitative analysis based on iodine content of the lesions in both arterial phase and portal phase was carried out. Results The GSI findings showed that the lesions were intra-luminal, extra-luminal or both intra-and extra-luminal soft tissue mass, the sizes were various, and they protruded either toward the inner side of stomach or the opposite or both. Among them, the diameter of 4 tumors in the low risk group ranged from 1 to 5 cm; in the intermediate risk group, 3 tumors had diameters from 1 to 5 cm, and 3 others were from 6 to 19 cm; in high-risk group, 18 tumors' diameter were between 6 to 9 cm, 2 were between 1 to 5 cm, and the rest 1 had multiple lesions in various sizes. Fifteen tumors occurred in gastric body, 10 occurred in gastric antrum, 4 were at the bottom of the stomach, and 1 had multifocal growth. Sixteen patients had internal and external growth of lesions, among whom 14 patients were at high risk; 10 patients' lesions were outside the cavity, including 6 patients at high risk and 1 patient at low risk; and 4 patients had lesions inside the cavity, including 3 patients at low risk. At the arterial phase the foci mildly strengthened, and they strengthened increasingly at the portal phase. The material value based water and iodine figure showed that material value based iodine of the lesions at both arterial phase and portal phase was higher than that in the normal gastric wall tissue, and the material value based iodine of the lesions at portal phase was higher than that at arterial phase (F=378.6 and 296.6, P<0.05). At arterial phase, the iodine content of the lesions in the mucosa was slightly higher than that in the submucosa and muscular layer (t= - 2.245, P<0.05). Conclusion CT gemstone spectral imaging can accurately show the external forms and internal changes of GST lesions and iodine content measurement can provide quantitative diagnostic information, therefore they can provide more effective information for clinical diagnosis.

Objective To evaluate the efficacy and safety of direct stenting technique in emergent percutaneous coronary intervention(PCI)for pa?tients with acute myocardial infarction(AMI). Methods Totally 460 consecutive patients with acute myocardial infarction who underwent emergent PCI during August 2010 to July 2013 were involved,among whom 346 patients were assigned to the control group(traditional balloon dilation and stenting),114 patients were assigned to the experiment group(direct stenting). The safety and efficacy of direct stenting technique was observed. Results In the control group,7 cases had no reflow during operation,2 cases had reflow after the pre?expansion and 5 cases after stent implanta?tion,no similar cases in the experiment group(P=0.125 9). The follow?ups showed the control group had 2 cases of major adverse cardiac events including 1 case of acute stent thrombosis who required urgent revascularization,and 1 case of cardiac death at four days after operation;the experi?ment group had 1 case of stent thrombosis,there was no statistically significant difference(P=0.730 7). Conclusion Direct stenting technique may be performed selectively for certain coronary diseases when performing emergent PCI for AMI.
