OBJECTIVE: To evaluate the effect of integrated traditional Chinese and Western medicine therapy on the progression of acute renal failure in patients with chronic renal insufficiency. METHODS: Thirty-two patients with chronic renal insufficiency developed acute renal failure recently were treated with Chinese herbs and western drugs intravenously and clysterizing of Chinese herbs liquid for 30 minutes, and the treatment course was 14 days. Assessment of liver and renal function, blood routine, electrolytes and endogenous creatinine clearance rate (Ccr) was performed before and 2 weeks after the treatment. RESULTS: The levels of hemoglobin (HB), white blood cell count (WBC) and serum electrolytes showed no significant changes after the treatment. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) decreased, while the level of Ccr increased significantly (P<0.05) after the treatment. The total effective rate was 65.6%. CONCLUSION: The integrated traditional Chinese and Western medicine therapy can effectively delay the deterioration of renal function in patients with chronic renal insufficiency accompanied by acute renal failure.

OBJECTIVETo study the antimetastatic effects of genistein on salivary adenoid cystic carcinoma (ACC-M) in vivo.

METHODSACC-M cells were exposed to genistein for 3 days. The treated cells and control cells were then injected into the tail vein of 20 nude mice, which were randomized into 2 groups. The mice were sacrificed at the sixth week after implantation. The lung metastasis rates and the number of metastases were detected. Apoptosis index (AI), the expression of VEGF and MMP-9 of the lung metastases were also observed.

RESULTSCompared to the control groups, the number of metastases was significantly reduced in genistein treated group (P < 0.05). The AI of ACC-M cells was higher in the treated group than in the control group (P < 0.05). The level of VEGF and MMP-9 expression were decreased in the treated groups (P < 0.05).

CONCLUSIONSGenistein has a moderate inhibitory effect on metastasis of ACC. Inducing apoptosis, inhibiting the expression of VEGF and MMP-9 are the mechanisms of antimetastatic effects of genistein on ACC-M in nude mice.

The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed, including those on their inhibition activities of coagulation factor Xa (FXa) and thrombin (FIIa). The results showed that the anti-FXa and -FIIa activities of enoxaparins with different degree of 1,6-anhydro derivatives (20.0%-39.7%) with similar structure characteristics, had decreasing tendency when the degree of 1,6-anhydro derivatives increased. Especially, the anti-FXa activity was sensitive to the change of the degree of 1,6-anhydro derivatives.
