Objective To observe and compare the analgesic effects of electro-acupuncture(EA)of “Tsusanli point” (St. 36) with various stimulation parameters. Methods Single wide dynamic range (WDR) and nociceptive specific (NS) neurons were recorded extracellularly in the dorsal horn of the rat lumbar spinal cord. The late train discharges (C-response) of the neurons evoked by intense electrical stimulation of the skin were used as a nocicepive response. The inhibitory effects of EA stimulation of the “Tsusanli point” (St. 36) with various intensities (1 and 6 mA) and frequencies (5, 20, 50 and 100 Hz) on the C-response were observed, respectively. Results A lower frequency (5 Hz) was appropriate to the high-intensity EA, while a higher frequency (50 Hz) was proper for the low-intensity EA. Conclusion The effect of EA on the spinal nociceptive transmission is both intensity- and frequency-dependent.

AIM: To observe the changes of glycemia and serum cholesterol and triglyceride in diabetic nephropathy rats and therapeutic effects of Xiaoke Keli Ji. METHODS: 3/4 nephrectomy was adopted firstly, three weeks later streptozotocin(STZ) was administered intraperitoneally to establish diabetic nephropathy model in rats. Animals were divided into four groups:model group, Xiaoke Keli Ji treatment group, positive control group and sham group. Changes of serum sugar and serum creatinine, cholesterol and triglyceride were examined at 1, 2, 3, 4, 5 weeks after STZ injection. Renal tissue samples were adopted at 6th week and studied by light microscopy. RESULTS: Model group demonstrated different degree of glomerular sclerosis. Lesions in treatment group were alleviated. Serum creatinine, serum sugar and serum cholesterol were higher at 1, 2, 3, 4, 5 weeks after STZ injection in model group than that of the sham group ( P
