The flavin-containing monooxygenase 3 (FMO3) is an important hepatic microsomal enzyme. Numerous mutations of FMO3 gene have been reported, and polymorphic varients of the gene have been identified. Several studies indicated that variability in the expression of FMO3 involved in some nitrogen, or sulfur-containing durg metabolism. This review summarizes the genetic polymorphism of FMO3 and its role in drug metabolism and toxicity.

The risk factors of traffic crash include drinking/drunk drive, accident proneness, fatigue driving, speeding, and poor vehicle quality. This article introduces the protection, emergency treatment, and basic scientific research of road traffic injury (RTI). As a public health issue, RTI is preventable, and personal factor is a key problem. It is important to establish an accurate and comprehensive RTI database, which may provide necessary information for the epidemiological research and crash prevention. The author also gives some suggestions on road traffic safety development in our country.

In the recent years,the earthquake occured frequently in the whole world which caused the increased incidence of crush syndrome (CS). The four limbs and torso will be bleeding and swelling when they are prounded and crushed from the heavy objects. The necrosis of muscular tissue causes massive production of toxin which leads to a series of symptoms including hypotension ,kidney dysfunction and so on. The serious acute kidney injury (AKI) will be vital. When CS-AKI ,the ascending velocity of urea nitrogen and K+ levels in the blood is quicker than those of general AKI;many kinds of immune cells are activated to engender a great deal of inflammatory mediators;the blood dynamics is often unstable. Therefore, it is advocated that the blood purification treatment should be carried early to eliminate excessive metabolic produces in vivo,to reduce the cardiovascular complication occurrence, and to avoid the irreversible change of the kidney function.

β-catenin is an important signaling transduetion and adhesion molecules.Mutation of the betacatenin gene,CTNNB1,is a common case in pediatric tumors,which may induce development and metastasis.In hepatoblastoma,48%have CTNNB1 mutation.In Wilms tumor,mutation only occurs in cases with WT1 gene mutation.In neuroblastoma,mutation is also found.

OBJECTIVE: To investigate the antagonistic effect of Salvia miltiorrhiza on cyclosporine A (CsA)-induced chronic nephrotoxicity. METHODS: 54 patients underwent renal transplantation were divided into 3 groups according to dosage of salvia miltiorrhiza: CsA+high-dose of salvia miltiorrhiza group, CsA+loe-dose of salvia miltiorrhiza group (trial group) and CsA control group (control group). Plasma concentration of CsA, serum creatinine (Scr), blood urea nitrogen (Bun), 24 h urines and 24 h urinary protein were recorded. The parameters of morphology and hemodynamics were compared among 3 groups. The differences of index among 3 groups were analyzed statistically. RESULTS: The level of Scr, Bun and 24 h urinary protein in CsA+high-dose of salvia miltiorrhiza group were decreased significantly while 24 h urines was increased, compared with other 2 groups. There was significant difference among 3 groups (P0.05). The intrarenal blood flow and renal arterial resistance index were increased significantly in CsA+high-dose of salvia miltiorrhiza group. CONCLUSION: High-dose of salvia miltiorrhiza combined with CsA can reduce the CsA-induced nephrotoxicity perfently.
