For interventional cardiologists, it is very challenging to do percutaneous coronary interventions （PCI） in lesions of ihe left main, bifilrcations or of chronic total occlusion types. However, it is more challenging to demonstrate an evidence based rationale supporting the indications of PCI in these lesions. In this article, new questions are raised on the benefits and the mechanism of benefits for PCI of bifilrcations revolving large side branches such as the diagonal （DIAG）,

目的探究C-反应蛋白(CRP)、乳酸脱氢酶(LDH)、红细胞沉降率(ESR)与肺炎支原体肺炎(MPP)恢复期患儿发生气道高反应性(AHR)的关系分析。方法回顾性选择2019年8月至2022年8月于西部战区总医院住院的MPP恢复期患儿102例,根据患儿是否发生AHR,分为AHR组(n=48)及非AHR组(n=54)。比较两组的CRP、LDH、ESR水平、肺功能指标[用力肺活量(FVC)、第1 s用力呼气容积(FEV1)、峰值呼气流速(PEF)与最大呼气中段流速(MEF25-75)]、气道反应性指标[基础呼吸传导率(Grs cont)、基础呼吸阻力(Rrs cont)、传导率下降斜率(SGrs)、特异性气道传导下降第35百分位(PD35)、最小诱发累积剂量(Dmin)],分析CRP、LDH、ESR水平与气道反应性指标的相关性,并采用受试者工作特征(ROC)曲线评估CRP、LDH、ESR对MPP恢复期患儿发生AHR的预测价值。结果AHR组的CRP、LDH、ESR水平分别为(47.34±7.65)mg/L、(315.26±68.32)U/L、(45.71±6.25)mm/h,均高于非AHR组[(26.21±6.28)mg/L、(284.53±61.09)U/L、(31.46±5.13)mm/h],差异均有统计学意义(P<0.05)。AHR组的FVC、FEV1、PEF、MEF25-75水平分别为(83.01±10.43)%、(74.35±9.27)%、(70.29±7.63)%、(75.54±9.25)%,均低于非AHR组[(87.82±12.06)%、(83.49±12.38)%、(78.11±9.54)%、(80.02±10.37)%],差异均有统计学意义(P<0.05)。AHR组的Grs cont、SGrs、PD35、Dmin水平分别为(0.13±0.03)L/(s·cmH_(2)O)、(0.03±0.01)L/(s·cmH_(2)O·min)、1.59±0.42、1.24±0.33,均低于非AHR组[(0.17±0.05)L/(s·cmH_(2)O)、(0.05±0.02)L/(s·cmH_(2)O·min)、4.06±1.15、3.97±0.82],Rrs cont水平为(8.75±1.63)cmH_(2)O/(L·s),高于非AHR组[(8.12±1.31)cmH_(2)O/(L·s)],差异均有统计学意义(P<0.05)。CRP、LDH、ESR与患儿的Grs cont、SGrs、PD35、Dmin水平均呈负相关(P<0.05),CRP、LDH、ESR与患儿Rrs cont水平均呈正相关(P<0.05)。ROC曲线分析结果显示,3项指标联合预测MPP儿童恢复期发生AHR的曲线下面积为0.878,均高于单一的CRP、LDH、ESR的0.804、0.674、0.760。结论CRP、LDH、ESR可作为MPP恢复期患儿发生AHR的重要标志物,可为临床评估患儿病情及用药提供参考。

In this study, we aimed to determine whether the main mitochondrial DNA （mtDNA） haplogroups of the Han people have an impact on spermatozoa motility, We recruited 312 men who were consecutively admitted to two affiliated hospitals of College of Medicine, Zhejiang University from May 2011 to April 2012 as part of fertility investigations. Semen and whole blood samples were collected from the men. We determined the mtDNA haplogroups by analysing the sequences of mtDNA hypervariable segment I and testing diagnostic polymorphisms in the mtDNA coding region with DNA probes, No significant differences were found in the clinical characteristics of the mtDNA haplogroup R and non-R （P〉0.05）. Our results suggest that mtDNA haplogroup R is a strong independent predictor of sperm motility in the Han population, conferring a 2.97-fold （95% confidence interval： 1.74-4.48, P〈0.001） decreased chance of asthenozoospermia compared with those without haplogroup R.
