误诊疾病数据库2004—2013年单病种误诊文献研究:颅内静脉窦血栓形成

颅内静脉窦血栓形成(cerebral venous sinus thrombosis,CVST)临床表现各异,体征不典型且多变,随着诊断技术及临床重视程度的提高,本病检出率逐渐升高,但误诊率仍较高。2004—2013年发表在中文医学期刊并经遴选纳入误诊疾病数据库的CVST文献共95篇,累计误诊病例674例,涉及误诊率文献29篇654例,误诊例数284例,误诊率43.43%。误诊范围涉及53种疾病,其中前4位误诊疾病是脑梗死、蛛网膜下腔出血、中枢神经系统感染、病毒性脑炎。主要误诊原因为经验不足而缺乏对该病的认识、缺乏特异性症状体征和未选择特异性检查项目。共438例误诊病例描述了误诊与疾病转归的关联,其中382例(87.21%)未因误诊误治造成不良后果。提示临床医师应提高对CVST的认识,对头痛、呕吐、颅内压升高、视力丧失者应考虑本病可能,及时行头颅磁共振血管成像和数字减影血管造影检查并仔细鉴别诊断,以减少误诊的发生。     

血清抗体检测在一起本地传播新冠肺炎聚集性疫情溯源调查中的应用

目的 在深圳市一起本地传播COVID - 19聚集性疫情溯源调查中，对重点涉疫人群开展抗体检测，帮助明确疫情扩散范围，追踪可能的源头。方法 采用流行病学调查、大数据手段锁定重点涉疫人群，除对其开展SARS - COV - 2核酸检测外，采用化学发光法检测抗体，对阳性者进一步开展流行病学调查和中和抗体检测，判断其在疫情传播中的作用。结果 该疫情的9名个案在病程中均检测到IgM抗体、IgG抗体阳性。5 606名涉疫人员检测了抗体，26人阳性，初筛阳性率为0.47%，其中11人IgG抗体阳性，15人IgM抗体阳性；但中和抗体实验和核酸检测均阴性。3人曾经出现过呼吸道症状，均否认与深港货车司机、国外入境人员、冷冻进口货物和发热呼吸道病例接触史。某口岸附近小区阳性率高于其他场所，差异有统计学意义（χ2 = 8.29，P = 0.004）。结论 通过核酸和抗体检测结果可判断，本起疫情传播范围较为局限；化学发光抗体检测法有一定假阳性率，可以作为新冠肺炎疫情溯源调查的辅助方法，对有流行病学史的涉疫人员进行筛查，但不宜对一般人群进行大规模筛查。

浅谈象思维在认识中药功效方面的应用

象思维是中医药学最主要的思维方法之一,尤其对中药功效方面的发展起着重要作用。象思维与中国传统文化思想有着千丝万缕的联系,它的发展与中国哲学思想密不可分;而中药学是研究中药的基本理论和临床应用并且在中华文化的滋养下发展壮大的学科,故象思维与中药学存在相互影响与作用,象思维对中药功效方面的影响深远。     

热毒宁治疗急性肠炎发热疗效观察

目的：观察热毒宁治疗腹泻发热的疗效。方法我院急诊2013年1月-2013年12月就诊的肠炎发热患者82例，将患者随机分为观察组（41例）和对照组（41例）。对照组给予对症处理，观察组在对照组的基础上，静脉滴注热毒宁注射液20 mL，1次/d。两组疗程均为3d。结果观察组治愈36例，好转4例，无效1例；对照组治愈23例，好转9例，无效9例。两组疗效比较差异有统计学意义（P＜0.05）。结论热毒宁注射液治疗急性肠炎发热疗效显著。

??Abstracts?? Objective To evaluate the association between TBX1 gene mutation and conotruncal defects ??CTDs?? using Meta-analysis. Methods Studies on the relationship between TBX1 gene mutation and CTDs were searched from the databases of Wanfang?? VIP?? CNKI?? PubMed?? Elsevier Science Direct and Cochrane Library from their establishment date to September of 2013. According to the standards of inclusion and exclusion?? articles were evaluated. Poor quality studies were excluded. Relevant data were extracted from eligible studies to conduct meta-analysis. R2.15.3 software was applied for statistical analysis. Results Eight eligible studies involving 851 patients were analyzed in the study?? including 6 English literatures and 2 Chinese literatures. Three studies found 15 gene mutations?? and 5 studies found 26 gene polymorphisms. The results of Meta-analysis showed that the pooled TBX1 gene mutation rate was 2.13%??95??CI??0.76%—5.87%??. Conclusion The TBX1 gene mutation rate is low in CTDs patients. TBX1 gene mutation may not be the main genetic factor for CTDs.     

Zephyr5826起搏器心房自动阈值管理的临床观察

目的动态观察Zephyr5826起搏器心房自动阈值管理(ACM)功能的开启情况、准确性及安全性。方法选取置入Zephyr5826起搏器患者68例,于置入术后第1,7天及1,2,3,6个月时随访程控,观察ACM功能的开启情况,手工测试心房起搏阈值并与ACM功能测定的值进行比较。结果 68例均完成随访。随访期内35例(51.50%)成功开启ACM功能,其中术后第1,7天及1,2,3个月时开启例数分别为14例(20.6%)、21例(30.9%)、26例(38.2%)、28例(41.2%)和32例(47.1%)。手工测试与ACM测试的心房阈值无差异。33例因起搏器自动测定心房刺激除极波(ER)过小不推荐开启ACM功能。随访期间心电图及动态心电图(Holter)均未见心房失夺获及感知不良。与普通电压和高电压起搏相比,自动阈值管理功能在心房输出方面分别节省50%,88%的能量消耗。结论 Zephyr5826起搏器ACM功能可以安全有效的应用低能量起搏心脏。部分患者术后因起搏器测定心房ER过小未能开启ACM功能,但在随访过程中ACM的开启比例逐渐升高。

??Objective??To find the difference in growth and development of children between full-term symmetric growth restriction??FSGR?? and full-term asymmetric growth restriction??FAGR?? through a general investigation of children born small for gestational age in Shanghai. Methods??This general investigation covered all children under 6 years old in Shanghai. Data on growth were retrospectively obtained from medical records. The P10 of birth head circumference/birthweight of the same gestational age and gender was used to distinguish FSGR and FAGR. Results??The sample contained 10 188 full-term SGA children among whom 8049 were FAGR and 2139 were FSGR. Up to 3 years old??both FSGR and FAGR failed to catch up in weight??height??head circumference and chest circumference. Growth restriction in FAGR was more serious. Significant difference could be seen in weight??t??-3.412??P??0.001?? and chest circumference??t??-2.526??P??0.012?? between FSGR and FAGR at 3 years old. Regarding growth speed??the growth rate of weight ??t??6.272??P??0.001????height ??t??9.143??P??0.001????head circumference ??t??6.063??P??0.001?? and chest circumference ??t??6.617??P??0.001?? were higher in FAGR 6 months after birth??while there was no difference after that. The BMI of FAGR was significantly lower than FSGR before 2 years old. The proportion of children in danger of being overweight was significantly higher in FSGR ??P??0.001??. Conclusion??Both FSGR and FAGR experience catch-up growth after birth??but not enough to catch up with normal children at 3 years old??especially in head circumference. In spite of severer growth restriction??the cath-up growth model of FAGR is superior to FSGR. The proportion of children in danger of being overweight is significantly higher in FSGR.
