Objective To explore the clinical effects of single-agent Xeloda (Capecitabine) therapy and the related risk factors in patients with advanced colorectal cancer. Method Seventy-eight patients with advanced colorectal cancer were treated with oral Xeloda, 1250 mg/m 2 twice daily, on days 1-14 every 21 days. At least 2 cycles were administered. The short-term clinical effects were evaluated, and the related risk factors were tested by Logistic regression analysis. Results The overall response rate was 32.05%with 5 cases complete response (CR), 20 cases partial response (PR), 31 cases stable disease (SD), 22 cases progress disease (PD). The Logistic regression analysis showed that the age (OR=1.52, 95%CI 1.015~2.319), fast blood glucose (OR=1.30, 95%CI 1.483~3.677), albumin (OR=1.98, 95%CI 1.526~2.572), ALT (OR=2.37, 95%CI 1.621~3.509) and AST (OR=2.21, 95%CI 1.526~2.572) were independent risk factors for inefficient treatment. Conclusion The single-agent Xeloda (Capecitabine) is an efficacious treatment for the patients with advanced colorectal cancer. However, the inefficient rate is also high and it relates to a variety of factors. We should comprehensively evaluate the patients to improve the short-term clinical effects.

The tri-plate horizontal mould with nonrigid surgical sponge inserts was developed to establish an industrial system for shaping surgical sponge which is used for cataract operation. The conception on an insertion mechanism of nonrigid flat inserts was firstly suggested by us. The prototype horizontal moulds with tri plate have been designed and manufactured. The experiment results of hundred thousand of times injection shaping have proved that the conception of the design is rational. The structure of shafting mould for nonrigid flats has been confirmed. Present article discussed the design and working mechanism of the insertion in the horizontal injection mould.

Hippophae rhamnoides is a traditional Chinese medicine with homology of medicine and food， which has the effects of relieving cough and resolving phlegm， strengthening the stomach and digestion， and promoting blood circulation and resolving blood stasis. H. rhamnoides contains not only flavonoids， phenols， proteins， vitamins， and amino acids but also abundant polysaccharides. In order to explore the functional value and current research status of H. rhamnoides polysaccharides， this study systematically summarized the extraction process， structural characteristics， pharmacological effects， and mechanism of action of H. rhamnoides polysaccharides by reviewing Chinese and foreign literature. The results showed that H. rhamnoides polysaccharides have anti-tumor， hypoglycemic， antioxidant， immune regulation， anti-inflammatory， and anti-hyperlipidemia functions and could improve intestinal microbiota. There were various extraction processes for polysaccharides， including hot water extraction， microwave extraction， ultrasonic extraction， enzymatic extraction， flash extraction， ultrasonic-microwave synergistic extraction， emerald hot water extraction， enzymatic-ultrasonic synergistic extraction， etc. Based on comprehensive analysis， hot water extraction is suitable for industrial development and application. However， multiple homogeneous polysaccharides have been isolated and purified from H. rhamnoides polysaccharides， but their efficacy， structure， and structure-activity relationship still need to be further explored and studied. This study can provide a reference for the research and development of H. rhamnoides polysaccharides.

The left ventricular (LV) myocardial remodeling process that occurs in various settings of congestive heart failure (CHF) had historically been attributed to intrinsic changes in the cardiac myocyte. However, it is now recognized that important changes also occur within the extracellular matrix (ECM) of the myocardium, contributing to the remodeling process. Matrix metalloproteinases are a family of proteolytic enzymes responsible for myocardial extracellular protein degradation.Several MMP species identified within the human myocardium may be dysregulated in congestive heart failure (CHF). The purpose of the present review is to present a brief overview of the matrix metalloproteinases (MMPs) within the myocardium that likely contributes to myocardial remodeling,to examine the results from basic studies to explore relationship with respect to MMPs activation and congestive heart failure.-
