RESUMEN
OBJECTIVE: To discuss the supervision mode of traditional Chinese herbal medicines and traditional Chinese medicine pieces in the production of traditional Chinese medicine preparations, and provide advice for the scientific and effective supervision of traditional Chinese medicine preparations with Chinese herbal medicines and Chinese medicine pieces. METHODS: Through the study of relationship between the quality, processing, preservation of medicinal herbs and the quality of preparations, the relationship between the implementation of Good Manufacture Practice (GMP) of traditional Chinese medicine preparations, and the relationship between imperfect quality standards and the quality of traditional Chinese medicine preparations, we put forward measures to solve the problems. RESULTS AND CONCLUSION: In the supervision of Chinese herbal medicines and traditional Chinese medicine pieces during the production of traditional Chinese medicine preparations, we should be closely around the core to ensure the quality of traditional Chinese medicine preparations, and should take different supervision modes of herbs and pieces according to different types and characteristics of traditional Chinese medicine preparations. At the same time, we should ensure the stability of the sources and origins of Chinese herbal medicines and ensure that manufacturing comply with GMP. We should standardize the preparation process of Chinese herbal medicine pieces by the traditional Chinese medicine preparation enterprises and implementation of traditional Chinese medicine pieces production filing system. And the quality standard of Chinese medicinal herbs and Chinese prepared herbs should be improved, with the objective to ensure the safety and effectiveness of traditional Chinese medicine preparations.
RESUMEN
Objective To observe the effect of sulodexide combined with dipyridamole on postoperative period of internal arterio‐venous fistula in the patients with chronic renal failure complicating diabetes .Methods 72 cases of chronic renal failure complica‐ting diabetes were randomly divided into two groups :sulodexide combined with dipyridamole group(group A) and dipyridamole group (group B) .Platelet ,fibrinogen(FIB) ,prothrombin time ,activated partial thromboplastin time ,triglyceride ,total cholesterol and hemortheological indexes were tested at different time points .The internal fistula patency ,blood flow volume after internal fis‐tula maturation and time of initial internal fistula use after internal arteriovenous fistula operationwere observed .‐Results (1)The patency rate of internal arteriovenous fistula in the group A was higher than that in the group B .(2) Compared with the group B , FIB and low‐shear rate of whole blood viscosity in the group A were decreased .(3)The time of internal fistula maturation in the group A was shortened ,but the blood flow volume had no significant difference between the two groups .Conclusion Sulodexide combined with dipyridamole is safe and effective for preventing the thrombogenesis after internal arteriovenous fistula operation ,its effect is superior to single dipyridamole .
RESUMEN
<p><b>OBJECTIVE</b>To compare the difference between digital subtraction angiography (DSA) and type B ultrasonography in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.</p><p><b>METHODS</b>Nineteen patients with high voltage electrical injury of upper limbs were enrolled in the study as burn group, and another 12 healthy volunteers as controls. The endovascular membrane, vascular wall thickness, intra-vascular blood flow and endovascular thrombosis formation of ulnar and radial arteries at wound site and in regions 5, 10 and 15 cm proximal to the wounds were examined by DSA and type B ultrasonography and compared with imagings of healthy volunteers as control. The injury degree of the ulnar and radial arteries was examined during operation for evaluation to corroborate with DSA and ultrasonography findings. Necrotic and/or thrombotic vessels were excised and sent for pathomorphological examination.</p><p><b>RESULTS</b>By DSA images abnormal signs as thrombosis, vascular lumen stenosis and blood flow deceleration were found in 14 ulnar and 11 radial arteries, and the signs were more pronounced in ulnar arteries. By type B ultrasonography, abnormal signs as roughing of tunica intima, swelling or exfoliation, thickening of vascular wall, lumen stenosis, decreased blood flow, even necrosis of vascular wall and thrombosis were identified in 19 ulnar and 16 radial arteries in burn group (P < 0.05 approximately 0.01). The blood flow in ulnar artery 5 cm to the approximal part of the wound edge was obvious lower than that of the control (31.60 +/- 13.90 ml/min vs 47.70 +/- 9.60 ml/min, P < 0.05).</p><p><b>CONCLUSION</b>Type B ultrasonography and DSA could be helpful in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.</p>
