[Risk assessment of renal dysfunction caused by occupational lead exposure].

Objective: To assess the risk of renal dysfunction caused by occupational lead exposure through epidemiological investigation.

Methods: The workers in a battery factory were selected as the subjects for the exposure and effect assessment. The occupational environmental monitoring data was collected and used to calculate the total external dose of lead.

[Risk assessment of nerve conduction velocity in workers exposed to lead].

Objective: To explore the dose-effect relationship between lead exposure and nerve conduction velocity, and to assess risk characteristics of nerve conduction velocity induced by lead exposure.

Methods: The external dose, internal dose (blood lead, urine lead) and the conduction velocity of peripheral nerve were examined. The benchmark dose of a population exposed to occupational lead was estimated to develop risk assessment of nerve conduction velocity in worker exposed to lead by use of BMDS (version 1.

[Survey of pharmacology of oleanolic acid].

Objective: To summarize the pharmacological function of oleanolic acid.

Method: Based on the documents and related achievements, the pharmacological function and its mechanism including its clinical use were summed up.

Result And Conclusion: Oleanolic Acid is a natural chemical which has wide-ranging function and abundant source.
