Objective:To evaluate the efficacy of liposomal bupivacaine (LB) for sciatic nerve block in mice.Methods:Twenty-four healthy adult male C57BL/6 mice, aged 6-8 weeks, weighing 25-30 g, were divided into 4 groups ( n=6 each) using a random number table method: 1.33% LB 80 μl group (group A), 1.33% LB 40 μl group (group B), 0.66% LB 80 μl group (group C), and 0.66% LB 40 μl group (group D). The sciatic nerve block was performed using the corresponding concentration of LB or the equal volume of LB in each group. The mechanical paw withdrawal threshold (MWT) was measured using Von Frey filaments immediately after sciatic nerve block, at 5 min of block, and every 1 h until MWT recovered to the baseline level. The sciatic nerve block time-MWT curve was plotted to calculate the area under the curve (AUC). Results:The time-MWT curves exhibited similar bimodal characteristics in each group. From the time point immediately after the blockade to the first MWT peak after the blockade, there were no statistically significant differences in the AUC among the four groups ( P>0.05). From the first MWT peak to the first trough, the AUC was significantly greater in A group than in B, C and D groups and in B and C groups than in D group ( P<0.05). From the first trough to the second MWT peak, there was no significant difference in the AUC between A group and D group ( P>0.05), and the AUC was significantly greater in B and C groups than in A and D groups ( P<0.05). From the second MWT peak to the baseline level, the AUC was significantly greater in A group than in B, C and D groups ( P<0.05), and there was no significant difference in the AUC among B, C and D groups ( P>0.05). In the total duration of the sciatic nerve block, the AUC was significantly greater in A group than in B, C and D groups and in B and C groups than in D group ( P<0.05).There was no significant difference in the AUC between B group and C group ( P>0.05). Conclusions:LB exhibits characteristic bimodal changes when used for sciatic nerve block; higher concentrations and volume of LB result in stronger and longer-lasting block effects in mice.

Objective To analyze the change of serum lipids and homocysteine level in patients with ischemic cerebrovascular disease.Methods A total of 150 patients with ischemic cerebrovascular disease (ICVD) were selected as ICVD group,and the patients were divided into short-term cerebral ischemia (TIA) group and cerebral infarction group (CI) group.Another 35 healthy people were selected as control group.Blood lipid index and plasma homocysteine level were compared among 4 groups.Results There was significant difference of Hcy between ICVD group,TIA group,CI group and control group (P<0.05).There was no significant difference of folic acid among the four groups (P>0.05).There were no significant differences in TC,TG and HDL-C between ICVD group,TIA group,CI group and control group (P>0.05),but there was significant difference in LDL-C (P<0.05).There were no significant differences in ApoA1 and ApoB between ICVD group,TIA group,CI group and control group (P>0.05),and there was significant difference in Fg (P<0.05).Conclusion Periodic detections of serum Hcy and blood lip index has a great value in prevention and treatment of patients with ischemic cerebrovascular disease.

Objective To observe the therapeutic efficacy of electroacupuncture at Baihuanshu (BL30) and Huiyang (BL55) for chronic prostatitis. Method Ninety patients were divided into an acupuncture-medication group and a Chinese medication group, 45 in each group, to respectively receive electroacupuncture at Baihuanshu and Huiyang plus oral administration of Chinese medication, and single Chinese medication treatment, 4 weeks as a treatment course. The therapeutic efficacy was evaluated by adopting the Chronic Prostatitis Symptom Index by National Institutes of Health (NIH-CPSI). Result The general score of NIH-CPSI dropped in both groups after intervention (P<0.05), while the decrease in the acupuncture-medication group was more significant (P<0.05), and it had a significantly higher therapeutic efficacy than the Chinese medication group (P<0.05). Conclusion Electroacupuncture at Baihuanshu and Huiyang can significantly improve the symptoms of chronic prostatitis, and it’s superior to oral administration of Chinese medication in comparing the clinical efficacy.
