目的探讨常见传染病甲襞微循环改变。方法对１４１２例传染病人及１００例健康人进行甲襞微循环观测。结果除流腮外，在伤寒、流脑、斑疹伤寒、乙脑、急慢性肝炎、肝硬化等疾病，甲襞微循环中、重度异常率均显著高于正常对照组（Ｐ＜０．００１）。管襻形态；异形增多＞５０％，在伤寒、流脑、乙脑、急慢性肝炎、肝硬化中明显高于正常对照组（Ｐ＜０． ００１）。管襻数减少，在流脑、乙脑中明显高于正常对照组（Ｐ＜０．００１）。斑疹伤寒、肝硬化管襻减少也高于正常对照组（Ｐ＜０．００１）。管径变细、短小，在乙脑、急性肝炎明显高于正常对照组（Ｐ＜０．００１），在伤寒、流脑、班疹伤寒中山高于正常对照组（Ｐ＜０．０５）。在急慢性肝炎、肝硬化中，充盈度不良者明显高于正常对照组（Ｐ＜０．００１）。血液流态：在伤寒、流脑、斑疹伤寒、慢性肝炎、肝硬化中，红细胞中、重度聚集明显高于正常对照组（Ｐ＜０．００１）。白色微栓出现率，伤寒明显高于正常对照组（Ｐ＜０． ００１）。白细胞增多，在流脑、乙脑中，明显高于正常对照和其他各病（Ｐ＜０．００１）。在伤寒、流脑、斑疹伤寒、急慢性肝炎、肝硬化中，粒缓流明显高于正常对照组（Ｐ＜０． ００１）。管周状态：在急慢性肝炎、肝硬
Objective To investigate the changes of nailfold microcirculation in common infectious diseases. Methods A total of 1412 cases of infectious diseases and 100 healthy subjects were observed for microcirculation of formazan. Results In addition to cheek gills, the rates of severe abnormalities were significantly higher in cases of typhoid, meningitis, typhus, Japanese encephalitis, acute and chronic hepatitis, liver cirrhosis and other diseases than in the normal control group (P <0.001) ). Morphology; Morphology increased more than 50%, in typhoid, meningitis, Japanese encephalitis, acute and chronic hepatitis, cirrhosis was significantly higher than the normal control group (P <0.001). The number of tubes reduced in meningitis and encephalitis was significantly higher than the normal control group (P <0.001). Typhus and cirrhosis were also significantly lower in the control group (P <0.001). The diameter of the tube was thinner and shorter. In JE, acute hepatitis was significantly higher than that in the normal control group (P <0.001), and in typhoid, meningitis and typhus were significantly higher than those in the normal control group (P <0.05). In acute and chronic hepatitis, liver cirrhosis, poor filling were significantly higher than the normal control group (P <0.001). Blood flow: In typhoid, meningitis, typhus, chronic hepatitis, cirrhosis, erythrocytes, severe aggregation was significantly higher than the normal control group (P <0.001). The incidence of white micro-emboli, typhoid fever was significantly higher than the normal control group (P <0.001). Leukocytosis in meningitis, encephalitis, was significantly higher than the normal controls and other diseases (P <0.001). In typhoid, meningitis, typhus, acute and chronic hepatitis, cirrhosis, grain retardation was significantly higher than the normal control group (P <0.001). Tube Week Status: In acute and chronic hepatitis, cirrhosis
