肝硬变门脉高压症血流动力学评估中MRA的临床应用

目的探讨磁共振血管成像(MRA)在门静脉高压症血流动力学研究中的应用价值。方法对38例肝硬变门静脉高压症病人和12例非肝硬变对照组病人进行MRA检查，检测门静脉系统解剖形态成像和血流量变化，分别与间接门静脉造影(IPVG)和多普勒超声(DUS)的结果进行比较。结果MRA成像结果优于IPVG，能很好显示门静脉系统各属支，对流速、流量的测定与DUS有良好相关性。结论MRA能较好显示门静脉系统解剖影像，并可测得其流速、流量，应成为门静脉高压症患者血流动力学研究的首选方法。     

CO2气腹环境对胃癌细胞黏附与侵袭转移的影响

Objective To investigate the influence of CO2 pneumoperitoneum on the adhesive and invasive ability of gastric cancer cells based on the expression of adhesive and invasive molecules. Methods With an artificial CO2 pneumoperitoneum model in vitro, human gastric cancer cells MKN-45, SGC-7901 and MKN-28 were exposed to 3 different CO2 gradients: 9 mm Hg, 15 mm Hg and control group (0 mm Hg). The expression of E-cadherin, ICAM-1, MMP-2 and VEGF-A were measured at 2 and 4 hours exposure by using RT-PCR, CytoMatrixTM kit and ECMatrixTM kit. The pretreated gastric cancer cells were injected into abdominal cavity of nude mice(2×106 cells per mouse). Five mice in each group were sacrificed 4 weeks later to record the number of tumor nodules in abdominal cavity. The remaining mice were kept for observation of survival time. Results The expression of E-cadherin (MKN-45: from 2.26 to 2.19, SGC-7901 :from 2.16 to 2.09、MKN-28 :from 2.06 to 1.99), ICAM-1 (MKN-45 : from 2.20 to 2.28、SGC-7901: from 2.10 to 2.18、MKN-28: from 2.00 to 2.08), MMP-2 (MKN-45:from 2.05 to 2.13、SGC-7901: from 1.95 to 2.03、MKN-28: from 1.85 to 1.93) and VEGF-A(MKN-45 : from 2.10 to 2.16、SGC-7901 :from 2.00 to 2.06、MKN-28: from 1.90 to 1.96) didn't change significantly with increasing pressure and time (P>0.05). The expression of adhesive and invasive molecules didn't change significantly between the experimental groups and the control group. There was no statistical significance of tumor metastasis in abdominal cavity of nude mice(MKN-45:from 22 to 23、SGC-7901 :from 20 to 22、MKN-28:from 21 to 22) and survival time(MKN-45 :from 23 to 21、SGC-7901 :from 22 to 21、MKN-28 :from 22 to 21) among all the groups. Conclusion Under low pressure and short time of CO2 exposure, the adhesive and invasive capacity of gastric cancer cells did not change significantly hence did not increase the possibility of neoplasm metastasis.

从瘀毒角度运用治未病思想防治肺结节

肺结节是指肺内出现的不规则病灶,影像学表现为高密度阴影。基于中医学对瘀、毒的认识,以 及肺结节的临床表现,对肺结节的防治进行探讨,分析认为瘀、毒既可以是肺结节的病理产物,也可以是致病 因素,且贯穿疾病的始终。肺结节疾病发展可分为三个阶段,第一阶段是邪犯肺脏,积聚成瘀;第二阶段是邪 毒炽盛,痹阻肺络;第三阶段是正气亏虚,瘀毒搏结。因部分肺结节可发展为早期肺癌病变,鉴于疾病转归的 特殊性,提出运用中医治未病思想防治肺结节,可根据瘀、毒作用的强弱、时间节点及位置,结合肺结节证候 演变的全过程,抓住存在的时间节点,判定结节的性质,确立治则治法,针对性控制病情,防止传变。     

糖化血红蛋白检测诊断妊娠期糖尿病的应用价值

目的评估糖化血红蛋白(Hb A1c)用于诊断妊娠期糖尿病(GDM)的临床价值。方法选取2018年1月-2019年1月在上海市嘉定区妇幼保健院诊治的GDM患者247例作为观察组,另选择同期健康孕妇247例作为对照组,对其同时进行75 g口服葡萄糖耐量试验(OGTT)和Hb A1c检查,分析两组Hb A1c、FPG及OGTT结果。结果两组孕妇空腹血糖(FPG)、口服糖耐量(OGTT)及糖化血红蛋白(Hb A1c)指标比较,观察组各项指数明显大于对照组,两组差异有统计学意义(P<0.05)。Hb A1c、FPG、OGTT 1 h及2 h诊断GDM的受试者工作特征(ROC)曲线下面积分别为0.705、0.779、0.884及0.905,Hb A1c联合FPG诊断GDM的受试者工作特征(ROC)曲线下面积为0.808。当Hb A1c取5.45%作为诊断界点时,其阳性预测值为94.7%,特异度可达到99.6%。结论 Hb A1c的检测,患者依从性好,可成为GDM诊断的有力补充。

新世纪的人文医学

随着时代的更替和历史进程的不断推移,一切学术的研究范畴都在不断地被扩充,被赋予新的含义和价值,而其概念也同时有了一些甚至是令人疑惑的变化,一些原本似是而非的理念逐步清晰,而在这些反思和重新评估之中,又不断地将我们的研究推向了另一个融合多学科、多领域的境地。几位社会学家对究竟什么是“新世纪的人文社会医学”?其概念和实际内涵是什么?概念之间的关系又如何界定等问题进行了探讨。他们就3个方面对这一命题进行畅所欲言的辩析,即:1什么是新世纪的人文社会医学?2提出现代人文社会医学概念的必要性。3新世纪的人文社会医学的哲学…
