Objective To investigate the effect on intestinal mucosal barrier dysfunction (IBF) of Xuebijing injection mediated by Toll-like receptor 4 (TLR4) signal pathway in rats of severe acute pancreatitis (SAP). Methods 24 Sprague Dawley (SD) rats were randomly divided into Sham group (n=8), control group (n=8) and treatment group (n=8). The SAP model was established by retrograde injection of 4.5% sodium taurocholate into the biliopancreatic duct in control group and treatment group, while control group was injected with the same amount of saline. In treatment group, Xuebijing injection (3 mL/kg) was injected via tail vein after 3h of modeling. All rats were monitored and sacrificed after 24 hours of modeling. Samples of pancreas and intestine were collected for pathologic determination. A fluorescent RT-PCR was used to determine the expression of TLR4 and NF-κB of small intestine. The serum levels of TNF-α, IL-6, amylase (AMS) and diamine oxidase (DAO) were measured by using ELISA. All parameters of three groups were compared. Results The expression of TLR4 and NF-κB of small intestine in control group and treatment group were higher than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). The expression of TLR4 and NF-κB of small intestine in treatment group were lower than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). Conclusion Xuebijing injection may not only reduce the expression of TLR4 and NF-κB of small intestine, but also alleviate the inflammation reaction of small intestine by interfering with TLR4 signal pathway, which may have a protective effect on intestinal mucosal barrier in SAP rats.

目的 探讨胸苷激酶1活性检测在胸腔积液鉴别诊断中的敏感度及特异度。方法 回顾性分析诊断明确的肺炎旁胸腔积液、结核性胸腔积液、癌性胸腔积液患者的临床资料,收集并检测三组患者胸腔积液标本中胸苷激酶1活性并进行比较。结果 三组胸腔积液胸苷激酶1含量分别为: 肺炎旁胸腔积液组: (1.18±0.73)pmol/L、结核组活性(1.31±0.64)pmol/L、癌性组(2.07±1.47)pmol/L。统计分析显示癌性组胸苷激酶1含量高于肺炎旁胸腔积液组及结核组,差异有统计学意义,而肺炎旁组与结核组胸苷激酶1含量无统计学差异。在诊断价值分析方面,当胸苷激酶1≥1.28 pmol/L时支持癌性胸腔积液诊断,但是当胸苷激酶1＜1.28 pmol/L时,无法鉴别肺炎旁和结核性胸腔积液。因此,胸苷激酶1对于癌性胸腔积液的诊断价值较好,对肺炎旁胸腔积液和结核性胸腔积液鉴别诊断效能差。临床可考虑与其他指标,如降钙素原、腺苷脱氨酶等指标联合诊断。结论 胸腔积液胸苷激酶1含量在癌性胸腔积液与非癌性胸腔积液的鉴别诊断中有较好诊断价值。
Objective To investigate the of thymidine kinase 1in differential diagnosis of pleural effusion. Methods A retrospective analysis of thymidine kinase1 activity in the parapneumonic pleural effusion and tuberculous pleural effusion and malignant pleural effusion were conducted. Results The thymidine kinase 1 of this three groups are respectively: parapneumonic group (1.18±0.73pmol/L), tuberculosis group (1.31±0.64pmol/L), and cancer group (2.07±1.47pmol/L). It was shown that the activity of thymidine kinase 1 in cancer group was higher than that of inflammation group and tuberculosis group, the difference was statistical significance, but there was no significant difference between parapneumonic group and tuberculosis group. It supported the diagnosis of malignant pleural effusion when thymidine kinase 1 was greater than or equal to 1.28pmol/L, but when the thymidine kinase 1 was less than 1.28pmol/L, it was impossible to distinguish parapneumonic pleural effusion and tuberculous pleural effusion. Therefore, the diagnosis efficiency of thymidine kinase 1 in malignant pleural effusion is well, but the diagnosis efficiency of thymidine kinase 1 in parapneumonic pleural effusion and tuberculous pleural effusion is not well. Conclusion The diagnosis efficiency of thymidine kinase 1 in malignant pleural effusion and non-malignant pleural effusion is well.
