目的:通过对腰俞穴中药穴位麻醉与肛周局部浸润麻醉进行临床对比研究,比较两种麻醉方式的优点和缺点,为肛肠手术麻醉选择提供指导。方法:收集临床病例80例,随机分为试验组和对照组(每组各40例):试验组采用复方薄荷脑注射液行腰俞穴穴位注射;对照组采用20 m L(1.5%盐酸利多卡因)注射液注射于肛门周围皮下组织、两侧的坐骨直肠窝。观察两组病例麻醉不良反应情况、术中疼痛情况、术中镇痛范围、术中肛门松弛情况。结果:两组病例采用两种不同麻醉方式后,镇痛范围、疼痛情况以及肛门的松弛情况差异有统计学意义(P<0.05);对两组病例的麻醉不良反应进行统计学分析,差异无统计学意义(P>0.05)。结论:在肛肠手术时,采用腰俞穴中药穴位注射麻醉较采用肛周局部浸润麻醉具有多方面优势。 相似文献
Several meta-analyses have demonstrated that the rs662 polymorphism in Paraoxonase 1 gene (PON1) gene is associated with coronary heart disease (CHD). However, it is still uncertain whether this polymorphism is associated with the plasma levels of oxidized low-density lipoprotein (Ox-LDL) and lipids. This meta-analysis is aimed to clarify the relationships between the rs662 polymorphism and plasma levels of Ox-LDL and lipids.
Methods
By searching in PubMed, Google Scholar, Web of Science, Cochrane Library, Wanfang, VIP and CNKI databases, 5 studies (1369 subjects) and 85 studies (46,740 subjects) were respectively identified for Ox-LDL association analysis and lipid association analysis. Standardized mean difference (SMD) was used to estimate the effects of the rs662 polymorphism on plasma Ox-LDL and lipid levels.
Results
The carriers of the variant R allele had higher levels of Ox-LDL (SMD?=?0.23, 95% CI?=?0.10–0.36, P?<? 0.01), triglyceride (TG) (SMD?=?0.06, 95% CI?=?0.01–0.11, P?=?0.02), total cholesterol (TC) (SMD?=?0.04, 95% CI?=?0.00–0.07, P?=?0.05) and low-density lipoprotein cholesterol (LDL-C) (SMD?=?0.04, 95% CI?=?0.00–0.08, P?=?0.04) than the non-carriers.
Conclusions
This meta-analysis suggests that the association between the PON1 rs662 polymorphism and CHD may partly be mediated by abnormal Ox-LDL and lipid levels caused by the R allele.
Pseudomonas aeruginosa (Pa) is a significant cause of morbidity and mortality, especially in cystic fibrosis patients. Its eradication is difficult due to a wide phenotypic adaptability and an increase of its resistance to antibiotics. After the failure of several recombinant vaccines which mainly triggered humoral response, live-attenuated vaccines received attention thanks to their ability to elicit a broad immunity with both humoral- and cell-mediated responses, essential to fight this pathogen. In this study, we developed an innovative and safer live-attenuated Pa vaccine based on a Killed But Metabolically Active (KBMA) attenuation method. KBMA Pa has been further rationally designed to overexpress beneficial effectors like the type 3 secretion system apparatus. We demonstrated that KBMA Pa elicits a high and broad humoral response in mice against several antigens of particular interest such as OprF and PcrV proteins. Moreover, we assessed cytokines in the serum of immunized mice and showed that KBMA Pa elicits Th1, Th2 and especially Th17 pathways of cell-mediated immune responses. Th17 pathway involvement was also confirmed after specific stimulation of helper T cells in immunized mice. Finally, we showed that this vaccine is safe and has a protective effect in a murine acute pulmonary infectious challenge. In conclusion, KBMA Pa is a new platform with high potential for the development of a vaccine against Pa. 相似文献
