In this paper, an analysis was made on the varieties and standards of labiatae medicinal plants used in Tibetan medicine. The results showed 71 species of labiatae plants in 21 genera (including varieties) recorded in relevant literatures, involving 44 varieties of medicinal materials. Specifically, seven species (9.9%) were intersected with traditional Chinese medicines (TCM), 19 varieties (43%) were recorded in Chinese medicinal material standards at all levels, and 27 species (38%) were source plants. In Tibetan medicine standards and literatures, there are great differences between Tibetan names and translated Chinese names and among varieties of source plants. Apart from a few of varieties intersected with traditional Chinese medicines had complete standards and regulations in Chinese Pharmacopoeia, most of species only had characters, microscopic, physical and chemical identifications in Standards Issued by Ministry of Health-Tibetan Medicine, Tibetan Medicine Standard and local standards. Therefore, the Tibetan medicinal material variety-source specification and quality standard system shall be promoted on the basis of literatures research, investigations for resources and current applications and modern pharmaceutical studies.

Objective To study the clinical efficacy of recombinant human epidermal growth factor (rhEGF) in the treatment of sacrococcygeal decubitus ulcers grade Ⅲ with direct polymerizing suture after appling rhEGF to reinforce wound bed preparation (WBP). Methods From January 2007 to October 2009, 60 patients with sacrococcygeal decubitus ulcers Grade Ⅲ, were divided into control group and treatment group. The ulcer size was 3 cm × 4 cm to 10 cm × 12 cm and all ulcers were infected for 15-70 d. Treatment group received traditional dressing change and appling rhEGF to reinforce wound bed preparation. Control group received traditional dressing change only. The operative technique that we used in two groups was direct polymerizing suture. Cure rate of stage Ⅰ and complication morbidities were analyzed. Results Cure rate of stage Ⅰ was 87% in treatment group and 70% in control group. Complication morbidities were 13% in treatment group and 30% in control group. The difference between these two groups was statistically significant (P ＜ 0.05). Conclusion Appling rhEGF to reinforce wound bed preparation before operation could make subsequent treatment more effective and improve the cure ratio of operation with decreasing complications and morbidities. And more, dissecting under fascia possesses the advantages of easiness to perform and rich blood supply.The method of appling rhEGF with direct polymerizing suture is a simple, high efficient approach for the first repairment of sacrococcygeal decubitus ulcers grade Ⅲ, especially desirable for the elderly.

Objective To investigate the induced-factors levels of venous thrombosis associated with the placement of peripherally inserted central catheters (PICC) in patients with malignant tumor,and establish intervention model accordingly. Methods 40 patients complicated with venous thrombosis after PICC were set as the thrombosis group, 40 patients without venous thrombosis were selected as the no-thrombosis group, 30 healthy cases were selected as the control group. All cases' serum samples were ob-tained to measure the levels of molecular biomarkers of the coagulation system, platelet parameters and molecular biomarkers of the fibrinolysis system. The results of the three groups were assessed. Results Patients in the thrombosis group were reported significantly higher levels of vWF, GMP140,TAT than those in both two other groups, but lower levels of ATⅢ. Higher levels of MPV and PCT were found in the throm-bosis group than those in both two other groups.Tthe data also showed higher PLG and PAI levels and lower levels of PLM in the thrombosis group. Conclusions From this study it shows that patients with malig-nant tumors during the placement of PICC have evident hypercoagnlahility, high- activated platelet and se-vere pre- thrombosis state caused by PICC. In treatment of malignant tumor patients with PICC, the level of coag-ulation system molecular markers, platelet parameters,fibrinolysis molecular markers shoud be used as a clinical routine and as the index of early intervention and evaluation of the PICC.

AIM: To investigate the expression of the nephrin in podocyte of the diabetic nephropathy(DN) rats and the mechanism of irbesartan-induced renal protection.METHODS: The DN model was established by a single injection of streptozotocin(STZ),and DN rats were randomly divided into 2 groups: model group and irbesartan treatment group.In addition,the normal rats served as a normal control group. All the rats were received daily gavage respectively for 8 weeks. The urinary protein quality in 24 hours,body weight(BW),kidney weight (KW),KW/BW,glucemia,urea nitrogen,creatinine,total cholesterol, triacylglycerol were detected with correlative methods and the pathological changes of kidney were also detected with optic microscope and transmission electron microscope.The expression of nephrin in podocyte were detected by immunohistochemistry. RESULTS: In DN rats, irbesartan reduced the urinary protein quality in 24 hours (P
