ABSTRACT
Objective To explore the value of reactive hyperemia index (RHI) in predicting the postoperative angina pectoris (AP) in the patients with percutaneous coronary intervention (PCI).Methods Three hundreds and forty-seven patients with coronary heart disease treated by PCI therapy were continuously enrolled in our department from October 10 2015 to August 10 2016.RHI was detected in all cases during hospitalization period by using the noninvasive endothelial function test (Endo-PAT) technique.Then the cases were divided into the control group (RHI≥1.67) and observation group (RHI ＜1.67) according to RHI results.The incidence of AP after discharge from hospital,rehospitalization rate due to AP,frequency and duration of AP were observed in the two groups.Results The AP incidence rates in the control and observation group were 17.04％ and 31.13％ respectively,the difference was statistically significant(P=0.003);the re-hospitalization rate due to AP was 2.22％ and 7.55％ respectively,the difference was statistically significant(P =0.035);the incidence rates of AP attack≥5 times were 6.67 ％ and 16.51 ％ respectively(P=0.008);the duration of AP was (6.39±2.68) min and (8.67±2.58) min,respectively(P=0.001);the Logistic regression analysis showed that the Syntax scores≥23 points and RHI＜1.67 were the risk factors for AP recurrence after PCI(OR=2.265,95％CI:1.354-3.787,P=0.002;OR=2.110,95％CI:1.228-3.628,P=0.007).Conclusion Reduced RHI is closely related with recurrent AP after PCI,increases the incidence,rehospitalization rate due to AP,attack frequency and duration of AP.
ABSTRACT
Objective To observe the effects of Yishen Tongluo Decoction (YTD) on the renal mRNA expression of transforming growth factor-β1 ( TGF-β1) and collagen Ⅳ ( ColⅣ) in membranous nephropathy ( MN) rats. Methods SD rats were randomly divided into normal group, model group, benazepril group (in the dosage of 10 mg·kg-1·d-1) , YTD group ( in the dosage of 20 g·kg-1·d-1) . The rats in various groups were given intragastric administration of corresponding agents. At the end of the fourth week, 24-hour urinary protein quantity, albumin ( ALB) , total protein ( TP) , triglyceride ( TG) , total cholesterol ( TC) , blood urea nitrogen ( BUN) , and creatinine (Cr) levels were observed. The mRNA expression levels of TGF-β1 and ColⅣ in renal tissue of rats were detected by immunofluorescence method, electron microscopy and real-time polymerase chain reaction (PCR) method. Results In the model group, urinary protein quantity in rats was increased, serum levels of TP and ALB were significantly lowered, serum levels of TC and TG were significantly increased, renal pathological changes were present, and mRNA expression levels of TGF-β1 and ColIV in renal tissue were up-regulated (P0.05) . Conclusion The therapeutic mechanism of YTD for MN is probably related with the inhibition of mRNA expression of TGF-β1 and ColⅣin renal tissue.
