The Journal of Practical Medicine 2016;32(5):809-811
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 study the risk factors of MRI for the prediction of collapse in patients with avascular necrosis of the femoral head.Methods Twenty-two patients (39 hips) diagnosed avascular necrosis of femoral head by MR were enrolled in our study.The following MR appearances were evaluated:bone marrow edema,joint fluids,signal intensity and location of the lesion.The volume and surface area of the necrosis zone were calculated.The time of follow-up was 18-84 months (median,25 months).Logistic regression analysis was used to predict the risk factors by SPSS 13.0.The maximum value of Youden index was selected as the critical point to predict the collapse of femoral head and to define the sensitivity,specificity and accuracy.Results In the 39 hips with femoral head necrosis,21 hips had collapse.Bilateral collapse occurred in 5 cases.In 25 hips with the necrosis surface larger than 25%,collapse occurred in 21 (84%); In 8 hips with the volume of femoral head necrosis larger than 30%,collapse occurred in all cases; 1n 33 hips with the necrosis locating at the superolateral quadrant,collapse occurred in 21 (63.6%); In 22 hips with necrotic areas showing heterogeneous signal intensity,collapse occurred in 18(81.8%) ;In 25 hips with large amount of joint effusion,collapse occurred in 16 (64%) ;in 18 hips with bone marrow edema,collapse occurred in 13 (65%).Joint fluid,heterogeneous signal intensity and lesions in the superolateral quadrant,volume ratio,and area ratio were the high risk factors,while bone marrow edema was a relatively low risk factor.The area under ROC curves for area ratio of NASA was greater than that for volume ratio (0.987 vs 0.902).When the critical value for area ratio was 26.7%,the true positive rate was 95.2%,true negative rate was 94.4%,and Youden's index was 0.896.Conclusions The collapse of necrosis of femoral head may result from many factors.The femoral head was easy to collapse when it had large enough area of necrosis and mixed signal intensity,a large amount of joint effusion,bone marrow edema,and superolateral quadrant location.The critical value for area ratio to predict the collapse of femoral head was about 26.7%.The area ratio is more accurate than volume ratio in predicting the collapse of necrosis of femoral head.

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.

Objective To analyze the CT and MRI performances of chromophobe cell renal carcinoma,to improve the understanding of the disease.Methods The CT and MRI performances of 16 patients with chromophobe cell renal carcinoma confirmed by post-operation pathology were analyzed retrospectively.Results Among 13 cases examined by CT,8 cases had homogeneous lesion including the homogeneous lesions density of 5 cases higher than that of normal renal parenchyma,and the other 5 cases had inhomogeneous density.After enhanced scan,the uneven essence ingredients were markedly enhanced in homogeneous density and inhomogeneous density cases,and the enhancement degree in arterial phase was lower than that of the renal cortex and higher than that of the renal medulla.Among 8 cases checked by MRI,2 cases had signal homogeneity with long T1 weighted imaging and long T2 weighted imaging signal,of which 5 cases appeared high signal in T1 weighted imaging flat lesions.The enhancement mode were similar with CT.In 5 patients examined by CT and MRI at the same time,their density,signal and the pattern strengthening were similar.Conclusions Chromophobe cell renal carcinoma is a rare malignant renal cell carcinoma,and CT and MRI can reflect the composition and hemodynamic changes.When homogeneity and high density or T1WI appeared high signal,disease was large and necrosis was less,and strengthening belt was appeared in lesions,it is value on diagnosis of chromophobe cell renal carcinoma.
