登革热是由登革病毒引起、经伊蚊叮咬传播的急性传染病,近年来已在全球热带和亚热带地区广泛流行,严重威胁公共卫生安全。目前临床上尚缺乏特异性抗病毒药物和高效的疫苗,临床治疗主要以中西医结合为主要模式,且两者在发病机制阐释、诊疗策略制定等方面各有侧重且互为补充。本文系统梳理登革热西医领域的流行病学特征、病理基础与发病机制及现代医学治疗现状,同时深入阐述中医对该病的病因病机与病位认知、辨证论治体系及中医药治疗进展,旨在为临床诊疗优化与科研方向拓展提供参考。
Dengue fever is an acute infectious disease caused by the dengue virus. In recent years, it has prevailed widely in tropical and subtropical regions, posing a severe threat to public health security. Given the lack of specific antiviral drugs and high-efficiency vaccines for dengue fever, its clinical treatment is predominantly based on integrated traditional Chinese and Western medicine. The two medical systems exhibit distinct focuses and complementary advantages in the interpretation of pathogenesis and the formulation of diagnosis and treatment strategies. This paper systematically reviews the epidemiological characteristics, pathological basis, pathogenesis and current Western medical treatment status of dengue fever, and further elaborates the etiology, pathogenesis, lesion location, syndrome differentiation and treatment system, as well as research progress of traditional Chinese medicine for this disease. It aims to provide references for the optimization of clinical diagnosis and treatment and the expansion of scientific research directions on dengue fever.
临床研究
临床研究中,我们会经常遇到多重检验的问题。当同时检验多个假设时,如何控制犯Ⅰ类错误的概率,保证结果的准确性,是研究者面对的首要问题。然而未对多重检验进行校正的文章比例仍较大。本文从简单的单个检验假设出发,回答为什么需要进行多重校正,何时进行多重校正,同时介绍总体错误率(FWER)和错误发现率(FDR)两种重要的错误率以及在此基础上的Bonferroni和Benjamini-Hochberg校正方法,从而避免因多重检验问题带来的混乱。
In clinical research, we often encounter the problem of multiple testing. When testing many hypotheses at the same time, how to control the type I error to ensure the accuracy of the results is the primary problem faced by researchers. However, the proportion of articles that didn't correct the multiple testing remains substantial. Starting with the simple hypothesis of a single test, this article provides an introduction to multiple testing issues, answers why and when multiple corrections are needed, introduces two important error rates which are family-wise error rate (FWER) and false discovery rate (FDR), and the Bonferroni and Benjamini-Hochberg correction methods based on them, thereby avoiding confusion caused by multiple testing.

目的 探讨生物电抗无创心排监测(bioreactance noninvasive cardiac output monitoring,NICOM)心指数(cardiac index,CI)和总外周阻力指数(total peripheral resistance index TPRI)对呼吸困难病因诊断的临床价值。方法 采用前瞻性观察性研究的方法 ,纳入急性呼吸困难或慢性呼吸困难急性加重的患者共113例,临床医师根据2010年中华医学会心血管病学分会编委会组织编写的《急性心力衰竭诊断和治疗指南》为金标准分为心力衰竭组(n=55)和非心力衰竭组(n=58),通过NICOM监测CI、TPRI,构建受试者工作特征曲线(receiver operating characteristic curve,ROC曲线),分析CI和TPRI对心力衰竭的诊断价值。结果 心力衰竭组患者的CI低于非心力衰竭组(P<0.001);心力衰竭组患者TPRI高于非心力衰竭组(P<0.001);利用ROC曲线进行分析,CI曲线下面积(area under the curve,AUC)为0.792(95%CI:0.708~0.875,P=0.000),当CI截断值取2.65L/(min·m2)时,诊断心力衰竭的敏感度为63.6%,特异度为87.9%;TPRI的AUC为0.733(95%CI:0.641~0.825,P=0.000),当TPRI截断值取2 353dynes.sec/(cm5·m2)时,诊断心力衰竭的敏感度为72.7%,特异度为67.2%;CI联合TPRI诊断心力衰竭的敏感度为80%,特异度为65.5%。结论 NICOM监测CI对心力衰竭所致的呼吸困难特异度高,联合TPRI监测可提高敏感度。
Objective To investigate the clinical values of etiological diagnosis by testing cardiac index CI and total peripheral resistance index TPRI using bioreactance noninvasive cardiac output monitoring NICOM in patients with dyspnea. Methods Prospective,observational study was taken in 113 adult patients admitted with dyspnea or acute exacerbation of dyspnea in stable disease. The patients were divided into two groups namely heart failure group (n=55)and non-heart failure group(n=58) according to the guidelines on the diagnosis and treatment of acute heart failure(2010) as the standard criterion. All patients underwent CI and TPRI test by using NICOM. Receiver operating characteristic curve(ROC curve) was plotted to evaluate the diagnostic value of CI and TPRI. Results Compared with non-heart failure group,the CI was worse(P<0.001),and the TPRI was elevated(P<0.001). ROC curve showed that the area under the curve(AUC) of CI was 0.792(95%CI:0.708~0.875,P=0.000). The cut-off of CI was 2.65L/min/m2,the sensitivity was 63.6%,and specificity was 87.9%. The AUC of TPRI was 0.733(95%CI:0.641~0.825,P=0.000). The cut-off of CI was 2 353dynes.sec/cm5/m2,the sensitivity was 72.7%,and specificity was 67.2%. The sensitivity of CI combined TPRI was 80%,and specificity was 65.5%. Conclusion NICOM monitoring CI have high specificity,and combined TPRI monitored may improve sensitivity for dyspnea caused by heart failure.

目的 研究超声脐血流与大脑中动脉血流定量检测用于胎儿宫内窘迫的临床应用价值。方法 纳入150例住院分娩孕妇作为研究对象,其中胎儿窘迫组72例,正常对照组78例。对所有孕妇行彩色多普勒超声检查,记录脐动脉(UA)和大脑中动脉(MCA)收缩期末期最大血流速度与舒张末期血流速度比值(S/D)、阻力指数(RI)及搏动指数(PI)。采用受试者工作曲线(ROC)分析超声UA和MCA血流检测在诊断胎儿宫内窘迫中的临床应用价值。结果 胎儿窘迫组UA的S/D、RI及PI均显著高于正常对照组(P<0.05),MCA的S/D、RI及PI均低于正常对照组(P<0.05)。UA对预测胎儿宫内窘迫的ROC曲线显示S/D、RI及PI的敏感度为0.986、0.958及0.944,特异度为0.614、0.625及0.534。MCA对预测胎儿宫内窘迫的ROC曲线显示S/D、RI及PI的敏感度为0.897、0.924及0.892,特异度为0.712、0.657及0.684。结论 产前超声联合检测UA和MCA血流参数有助于筛查胎儿宫内窘迫,提高诊断准确性,指导临床。
Objective To study the clinical value of ultrasonic quantitative detection in blood flow and middle cerebral artery blood flow in fetal distress. Methods 150 hospitalized pregnant women were included in the study, including fetal distress group (n=72) and normal control group (n=78). Color Doppler ultrasonography was performed on all pregnant women. The maximal systolic blood flow velocity and end diastolic blood flow velocity ratio(S/D), resistance index (RI) and pulsatility index (PI) of the umbilical artery (UA) and the middle cerebral artery (MCA) were recorded. The application value of ultrasonic UA and MCA blood flow detection were analyzed by the receiver operating curve (ROC). Results The S/D, RI and PI of UA in fetal distress group were significantly higher than those in normal control group(P<0.05). The S/D, RI and PI of MCA in fetal distress were significantly lower than those in normal control group(P<0.05). The ROC of UA and MCA showed that S/D, RI and PI of sensitivity were[0.986,0.958,0.944 vs 0.897,0.924,0.892],the specificity were[0.614, 0.625,0.534 vs 0.712,0.657,0.684]. Conclusion The prenatal ultrasound combined detection UA and MCA blood flow parameters are helpful for screening fetal distress, improving diagnostic accuracy and guiding the clinical.

Objective To explore the prenatal care strategy of applying Chinese medicine dialectical care to promoting cervical ripening of full-term pregnant women with qi-blood deficiency and its clinical effect. Methods We chose 180 first-time, full-term pregnant women with single fetus cephalic presentation who were diagnosed as with qi-blood deficiency and then randomly divided them into three groups, 60 in control group with oxytocin and usual care; 60 in group of Chinese medicine dialectical care, which provided oral use of Chinese medicine and dialectical care after those women being admitted to hospital; 60 in blank group with usual observation and care. We did Bishop assessment of neck of uterus before and after treatment in these three groups, conducted qualitative test in FFN (Fetal Fibronectin), the secreta from vagina and neck of uterus, and observed delivery outcome as well as the influence to mother and child. Results Compared with control group and blank group, the group ofChinese medicine dialectical care was outstanding in terms of labor rate, vaginal delivery rate, and FFN test(P<0.05). Conclusion Chinese medicine dialectical care boosts cervical ripening of full-term pregnant women with qi-blood deficiency. It is helpful to increase natural labor rate, reduce high-risk delivery, and promote health of mother and child. Therefore it is worth to be popularized.
