OBJECTIVE:To investigate the therapeutic effect of Huangqi injection in the treatment of periodontitis in rats.METHODS:Periodontitis model was induced by exposing and lacerating,supplying a high-glucose diet.They were given 8.0 g?kg-1 Huangqi injection for 10 days.Therapeutic effect was evaluated with blood biochemical index and clinical index.RESULTS:Huangqi injection could decrease the level of leukocytes and neutrophils in periodontitis rats while had no effect on erythrocyte,platelet and hemoglobin.Huangqi injection could decrease the level of plaque index (PLI),bleeding index (BI),alveolar bone loss (ABL) and tooth mobility (TM) while had no significant effect on probing depth (PD),periodontal bone support (PBS) and periodontal bone loss (PBL).CONCLUSION:Huangqi injection has therapeutic effect on periodontitis in rats.

Objective To evaluate the effect of α-lipoic acid on the cognitive function after cardiopulmonary bypass (CPB) in diabetic rats.Methods Health adult male Sprague-Dawley rats,weighing 400-500 g,aged 16-22 weeks,were used in this study.Diabetes mellitus was induced by intraperitoneal streptozocin 60 mg/kg and confirmed by blood glucose≥ 16.7 mmol/L.Thirty-two diabetic rats were randomly divided into 2 groups (n =16 each):diabetes mellitus group (group D) and α-lipoi cacid group (group L).In group L,α-lipoic acid 30 mg/kg was intraperitoneally injected once a day for 7 consecutive days starting from 6th week after induction of diabetes mellitus.While the equal volume of normal saline was given instead in group D.The two groups underwent CPB after the last administration.Before induction of diabetes mellitus,on 5th week after induction of diabetes mellitus,before CPB,at the end of CPB,and on 3 and 5 days after termination of CPB,10 rats were chosen from each group and venous blood samples were collected for determination of plasma TNF-α and IL-10 concentrations.Ten rats in each group were chosen for detection of cognitive function before induction of diabetes mellitus,before CPB and 5 days after termination of CPB.The rats were then sacrificed and hippocampi were isolated for measurement of NF-κB activity.Results Compare with group D,the plasma TNF-α concentration,times of electric shock and activity of NF-κB in hippocampal tissues were significantly decreased and the plasma IL-10 concentration was increased in group L (P ＜ 0.05 or 0.01).Conclusion α-lipoic acid can improve the cognitive function after CPB in diabetic rats and inhibition of activation of NF-κB in hippocampal neurons is involved in the mechanism.

Objective To evaluate the pharmacokinetics of ropivacaine following lumbar plexus combined with sciatic nerve block for knee arthroscopy. Methods After obtaining written informed consent 16 ASAⅠorⅡpatients of both sexes (8 males ,8 females) scheduled for unilateral knee arthroscopy under lumbar plexus combined with sciatic nerve block with ropivacaine were randomly divided into 2 groups (n = 8 each) : group A received 0.5% ropivacaine 30 ml (15.0 mg) and group B received 0.75% ropivacaine 30 ml (22.5 mg) . Blood samples were taken from radial artery immediately after and at 5, 10, 15, 30, 45, 60, 120 and 180 min after drug administration for determination of plasma ropivacaine concentration by HPLC. The pharmacokinetic parameters were calculated using 3p97 computer program. Results The two groups were comparable with respect to sex ratio (M/F), age, body weight, height, duration of operation and amount of fluid infused. The main pharmacokinetic parameters in group A and B were: Cmax(1.4?0.3) mg?L-1 and (2.7?0.9) mg?L-1;AUC (3.88?0.28) mg?L-1?h-1 and (7.13?0.65) mg?L-1?h-1;t1/2?(0.44?0.19)h and (0.60?0.34)h; t1/2?(3.4?0.4)h and (2.4?0.5)h. The Cmax in group B was significantly higher than that in group A. The Cmax of ropivacaine reached 3.57 mg?L-1 in group B. No patient developed central nervous system or cardiac toxicity.Conclusion The plasma concentration versus time curve is fitted to two-compartment pharmacokinetic model. Lumbar plexus combined with sciatic nerve block with 0.5% ropivacaine 30 ml is safer.

AIM: To conclude the characteristics of flash visual evoke potentials (FVEP), and pattern visual evoke potentials (PVEP) of the healthy school-age children.And to compare the two methods, in order to find the association of them, and to find the impact of sex, age, and the other biological variables.METHODS: A total of 101 healthy children were recruited (age from 5 to 14.4y, mean 8.27y).Each of them was underwent FVEP and PVEP examinations.Then the results were statistically analyzed by SPSS 13.0.RESULTS: The curves of PVEP are simple and stable, while FVEP waveforms are variable.The latency of P100 of females is shorter than males.However there was no significant difference for FVEP in sex control.To compare the parameters between the two hemispheres, the amplitude of P100 of left eyes were higher than the right side.FVEP showed no difference in the two hemispheres either.There was no significant difference for age-dependent decreased in neither PVEP nor FVEP.And in a regression analysis of the FVEP and PVEP, we could not find the inner connection of the two methods.CONCLUSION: Based on our research, there were no significant differences in age level or sex control in the period of school-age children.And there is no inner connection of the two methods.The differences between the PVEP and FVEP results might be due to the origin of these two responses.And these two stimuli should be used in a complementary manner not as alternative examinations.
