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.

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.
