Fifteen patients were received large dose methylcobalamin injection for two weeks as treatment group, another eleven patients were received muscular injection VitB1 100mg/ d, VitB12 500ug/ d for two weeks as control group. After 2 weeks treatment the subjective symptoms and signs were significantly improved with a total effective rate of 82.9% in the treatment group however the effective rate only has 52.0% in the control group. The result has obvious difference in statistics nerve MCV in median common peroneal nerve, SCV in median and superficial peroneal nerve were improved significantly in the treatment group and no such changes were observed in the control group. So, large dose methylcobalamin is an effective and safe agent for treatment of diabetic peripheral neuropathy.展开更多

The urinary N-acetyl-13-D-glucosaminidase （UNAG） was chosen as an effect biomarker. The UCd BMDLs for UNAG ranged from 2.18μg/g creatinine （cr） to 4.26μg/g cr in the populations of different provinces. The selection of the sample population and area affect the evaluation of the BMDL. The reference level of UCd for renal effects was further evaluated based on the data of all 6103 subjects. With benchmark responses （BMR） of 10%/5%, the overall UCd BMDLs for males in the total population were 3.73/2.08 μg/g cr. The BMD was slightly lower in females, thereby indicating that females may be relatively more sensitive to Cd exposure than are males.展开更多
