扶正化瘀片治疗肝炎后肝硬化的研究

Objective: To investigate the efficacy and safety of the Fuzheng Huayu Tablet (扶正化瘀片, FZHYT), which is used to reinforce qi and resolve stasis in patients with posthepatitic cirrhosis (PHC). Methods: A multicenter, randomized, controlled clinical trial was conducted in 180 patients with PHC. The patients were randomly assigned using random numbers to a treatment group treated with FZHYT and a placebo group; the treatment course was 6 months for both groups. Overall response, adverse events (AEs), and the 2-year survival rate were assessed after treatment. Evaluations were made on changes in liver function, liver fibrosis, coagulation, hemodynamics, degrees of esophagogastric varices, ascites, quality of life (QOL), and scores of main symptoms. Results: The overall response was significantly higher in the treatment group than the placebo group (86.7% vs. 62.2%, P<0.01). Patients in both groups had signi?cant improvements in liver function [total bilirubin (TBIL), albumin (ALB)], liver fibrosis [hyaluronic acid (HA), type Ⅳ collagen (CⅣ)], coagulation [prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), and thrombin time (TT)], hemodynamics portal venous flow (PVF), and splenic vein flow (SVF) after treatment. Between-group comparisons showed that compared with the placebo group patients in the treatment group achieved significantly greater improvements in TBIL, ALB, HA, C Ⅳ, PT, APTT, PVF, SVF, time to ascites resolution, 2-year survival, QOL, and symptom scores (P<0.05 or P<0.01). There were no significant AEs during the treatment. Conclusions: FZHYT is effective and safe for the treatment of hepatic cirrhosis as it is associated with improved liver function, liver ?brosis, coagulation, portal hypertension state, QOL, 2-year survival rate, and fewer AEs.     

新生脉片治疗慢性充血性心力衰竭临床观察

The Influence of Engravings on the Sticking of Tablets. Investigations with an Instrumented Upper Punch

The purpose of this study was to investigate the influence of engravings on the sticking of tablets. Therefore, an instrumented upper punch capable of measuring the pull-off force, which occurs when the punch detaches itself from the upper surface of a tablet, was equipped with small cones of different angles between the punch face and the cones’ lateral face. The cones could be screwed into a threaded hole at the center of the punch face. The adhesion forces of two formulations known to stick to engravings during production increased with a greater steepness of the cones’ lateral face. With microencapsulated acetylsalicylic acid, no quantitative differences could be found between the adhesion forces obtained with plain and modified punch faces, indicating that the sticking behavior of the substance was not affected by shear forces. Starch 1500® showed higher adhesion force signals in comparison to those obtained with a plain punch face. Microcrystalline cellulose, which gave no adhesion force signals with a plain punch face and did not stick to the cones, showed distinct pull-off signals. The instrumented upper punch equipped with shear cones is a valuable instrument for detecting the adhesion caused by engravings and is therefore a helpful tool for tablet formulation development and the design optimization of tablet identification.
