Fourly adult healthy patients were separately anesthetlzed with (1 )0. 95% isoflurane; (2) fentanyl 5g/kg and thiopentone 4 mg/kg; (3) upper thoracic epidural blockage and (4 ) lumbar epidural blockage,Continuous 5 min ECG were recorded before and a fier anesthesia with spectral analysis of heart rate varlability (HRV) performed by computer program. For power spectral measurement,three frequency band of HRV were evaluated and the effects of each anesthesia were compared. HRV reduced markedly in patients using 0. 95 % isoflurane. with decreases of frequency by 91. 7% (low frequency ), 84. 4% (mid frequency ). and 82% (high-frequency) respectively. In patients after administration of fentanyl 5g/kg, mid and high-frequency components declined 63. 4 % and 65. 4 %. Upper thoracic epidural block restrained the mid and low frequency components by 66 % and 65 % respectively, Following lumbar epidural block the pattern of HRV components did not change. It is concluded that different anesthesia techniques may have significant different effects on autonomic reflexes as presented by HRV.

Objective To investigate the relationship of plasma homocysteine with the genotype distribution of MTHFR and MTRR among Chinese Han women in Xiangtan. Methods MTHFR C677T, A1298C and MTRR A66G geno?typing was analyzed to detect the distribution of gene polymorphisms among 1 701 women from Xiangtan city then the data were compared with the rest of the Han women in Zibo, Zhengzhou, Yantai, Zhenjiang, Songzi, Huizhou, Qionghai. Plasma Hcy levels from 110 patients were measured and analyzed the correlation with gene polymorphisms. Results The frequency of MTHFR C677T genotype and allele frequencies in Xiangtan is 12.6%which is higher than Huizhou (10.9%) and Qionghai (6.1%) but lower than Zibo (43.6%), Zhengzhou (36.8%), Yantai (32.2%), Zhenjiang (21.8%) with statistically significant dif?ference (P<0.05). There is no significant different in MTHFR C677T between Xiangtan and Songzi. The frequency of MTH?FR A1298C genotype and allele frequencies in Xiangtan is 4.8%which is lower than Qionghai(7.1%)but higher than Zibo (1.4%),Zhengzhou(2.4%), Yantai(1.8%), Zhenjiang(3.5%)and Songzi(2.6%)with statistically significant difference. The frenquency of MTRR A66G genotype and allele frequencies in Xiangtan is 6.8%which is higher than Zibo (4.8%) but lower than Qionghai (9.3%) with statistically signifcant difference. Plasma Hcy concentration correlate with MTHFR C677T, Hcy concentration in TT population is higher than that in CT and CC population(μmol/L:8.52±2.01 vs 5.94±1.47 vs 5.71± 0.18);Plasma Hcy concentration also correlate with MTHFR A1298C and Hcy concentration in CC population is higher than AA and AC population(μmol/L:9.83 ± 2.26 vs 6.35 ± 2.13 vs 5.55 ± 1.75);Plasma Hcy concentration does not correlate with MTRR A66G. Conclusion The gene polymorphism of MTHFR C677T, A1298C and MTRR A66G among the Han women in Xiangtan was statistically different from other selected regions of China. Mutation in MTHFR C 677T and A1298C were associated with elevated plasma levels of Hcy.
8.Study on the value of exogenous bFGF in the treatment of brain injury.
Chinese Journal of Traumatology 2000;3(3):131-135
OBJECTIVE: To investigate the relation betwe en necrosis and apoptosis in the hippocampus of exogenous bFGF on this process. METHODS: With Marmarou's method we produced a severe diffuse brain injury and studied the changes in the hippocampus by adapting a modified T dT-mediated dUTP-biotin nick end labeling (TUNEL) method. At the same time we observed the effect of exogenous bFGF on neuronal necrosis and apoptosis. RESULTS: We found that together with cell necrosis there was an increase in the number of apoptotic neurons in the hippocampus CA2-3 sectors a s early as 4 h after injury, with numbers reaching a maximum at 7 d. Exogenous b FGF resulted in a definite reduction in the amount of necrosis and apoptosis. CONCLUSIONS: Neuronal necrosis and apoptosis occur in combinati on after brain injury and that one of the causes may be the insufficience expres sion of the bFGF gene in the hippocampus after severe injury. Exogenous bFGF and similar substance may prove clinically useful after brain injury by reducing ce ll necrosis and apoptosis.
