急性有机磷中毒动物血糖及胆碱酯酶活力的动态监测研究

目的：动态监测急性有机磷中毒动物在急性有机磷中毒及解救过程中血浆的乙酰胆碱酯酶活性和血糖值变化，依据此两项指标与中毒程度的相关性，为临床救治提供新的方法以及实验依据。方法：通过耳缘静脉注射5％敌百虫溶液（2mL／kg）先后对12只家兔建立急性有机磷中毒模型，分别在模型动物处于正常、轻、中、重度中毒和救治的时段采血，动态监测血浆乙酰胆碱酯酶活力和血糖两项指标变化。结果：在急性有机磷中毒过程中，血糖值升高与乙酰胆碱酯酶活力降低相比较，血糖浓度动态变化与中毒轻重程度相关性较好，并能体现机体对中毒的应激程度。结论：血糖浓度能较好地反映有机磷中毒深度以及机体应激程度，可作为临床评估危重程度的动态性快速诊断指标。     

抗病毒治疗对乙型肝炎病毒感染者肾移植术后临床转归的影响

目的 探讨乙型肝炎病毒感染者肾移植术后临床转归及治疗对策.方法 将术前乙肝病毒标志物阳性(HBsAg阳性、HBeAg阳性或HBeAb阳性、HBV DNA阳性或阴性)的32例肾移植术后患者分为抗病毒治疗组和无抗病毒治疗组两组.观察两组(术前1周至术后9年)的肝功能(ALT、AST、TBIL、PT)变化、病毒复制(HBV DNA)及存活情况.结果 抗病毒治疗组23例患者肝功能损害复常率为82.60%,存活率为82.60%,HBV DNA(PCR法)下降(≥2 log10)或保持低复制率为86.95%;未抗病毒组9例患者肝功能损害复常率为22.22%,存活率为11.11%,HBV DNA(PeR法)下降(≥2log10)或保持低复制率为11.11%.抗病毒组肝功能复常率、存活率及HBV DNA下降或保持低复制率高于无抗病毒组,两组比较差异有统计学意义(P<0.05).19例拉米夫定治疗患者6例出现病毒学反弹31.58%,1例加用阿德福韦酯,2例换用恩替卡韦后好转,其余3例肝功能衰竭死亡.结论 持续有效的抗病毒治疗可以有效控制乙肝病毒复制,促进肝功能恢复,减少肝衰竭发生,提高乙肝病毒感染者肾移植术后患者存活率.在治疗过程中出现病毒学反弹应及时换用或加用有效药物减少肝衰竭发生.     

慢性乙肝患者血清趋化因子RANTES水平与肝功能生化指标等的相关性研究

Objective To investigate the level of the serum chemokine RANTES and its correlation with serum biochemical indices of liver function test, HBeAg and HBV DNA load in patients with chronic hepatitis B.Methods 144 patients with chronic hepatitis B (observed group) and 18 normal cases (control group) were enrolled in this study. The serum level of chemokine RANTES was detected with an ABC-ELISA assay. Statistical analysis was performed on the software of SPSS13.0. Results The serum chemokine RANTES level in the observed group (3930.12 ng/ml±2856.96) ng/ml was significantly higher than that in the control group (329.46 ng/ml±152.23) ng/ml. The results from the observed group indicated the positive correlation of serum RANTES level with indices of liver function test, including ALT (r=0. 197, P=0.018), AST(r=0.239, P=0.004) and TBil (r=0.316, P=0.001), but did not with PTA (r=-0.078, P=0.357). Neither difference of serum chemokine RANTES level between HBeAg-positive group and HBeAg-negative group nor that between high HBV DNA load group (≥105 copies/ml) and low HBV DNA load group (< 105 copies/ml) were statistically significant (P=0.407 and 0.185, respectively). Conclusions Serum chemokine RANTES level in patients with chronic hepatitis B elevates significantly and is not affected by HBeAg or HBV DNA load. Its positive correlation with indices of liver function test indicates that RANTES might play an important rule in the pathogenesis of chronic hepatitis B.
