肿瘤坏死因子-α-308基因对导管相关性脓毒症患者病情的影响

目的探究肿瘤坏死因子-α(Tumornecrosis factor-α,TNF-α)-308基因对导管相关性脓毒症(Catheter related sepsis,CRS)患者病情的影响,旨在为临床治疗CRS提供科学依据。方法选取2017年7月-2018年10月于浙江大学医学院附属杭州市第一人民医院接受治疗的86例CRS患者为研究对象,按照是否并发多器官功能障碍综合征将患者分为试验组和对照组,对照组共48例,未并发多器官功能障碍综合征,试验组共38例,并发多器官功能障碍综合征,分析两组患者TNF-α-308基因多态性差异,使用多因素Logistic回归分析CRS患者并发多器官功能障碍综合征的危险因素。结果试验组GA基因型频率34.21%、AA基因型频率50.00%、高G等位基因频率18.42%均高于对照组,GG基因型频率52.63%、A等位基因频率28.95%均低于对照组,差异均具有统计学意义(P<0.05);多因素Logistic回归分析结果显示,低GG基因型频率、低G等位基因频率、高GA基因型频率、高AA基因型频率、高A等位基因频率是CRS患者并发多器官功能障碍综合征的危险因素(P<0.05)。结论TNF-α-308基因与CRS患者病情密切相关,GG基因型频率和G等位基因频率降低,GA基因型频率、AA基因型频率、A等位基因频率升高会加重患者的病情,增加多器官功能障碍综合征的发生风险,临床上应该加以重视。     

EMMPRIN、VEGF-C及淋巴管密度与乳腺癌浸润和转移的关系

目的探讨细胞外基质金属蛋白酶诱导因子(extracellular matrix metalloproteinase inducer,EMMPRIN)和血管内皮生成因子-C(vascular endothelial growth factor-C,VEGF-C)蛋白表达及D2-40标记的淋巴管密度(lymphatic vessel density,LVD)与乳腺癌其浸润和转移的关系。方法免疫组化法检测乳腺增生组21例、导管内癌组10例、浸润性导管癌68例病灶内EMMPRIN、VEGF-C和LVD情况。计数资料比较采用χ2检验进行分析,相关性分析采用Spearman等级相关分析,计量资料三组间比较采用方差分析,两两比较采用LSD法,P0.05为差异有统计学意义。结果三组EMMPRIN、VEGF-C的阳性率比较,差异均有统计学意义(均P0.05);与乳腺增生组比较,导管内癌、浸润性导管癌组EMMPRIN、VEGF-C的阳性率显著升高,差异均有统计学意义(均P0.05);乳腺增生组的LVD为(8.38±3.18),导管内癌、浸润性导管癌组分别为(9.80±2.78)、(10.82±5.51),三组LVD比较,差异有统计学意义(P0.05)。EMMPRIN和VEGF-C的阳性表达与有无淋巴结转移和淋巴结转移个数有关,差异均有统计学意义(均P0.05)。不同组织学分级EMMPRIN和VEGF-C的阳性率比较,差异均有统计学意义(均P0.05)。乳腺癌组织中EMMPRIN与VEGF-C的表达呈正相关(rs=0.390,P0.05)。结论 VEGF-C在乳腺癌淋巴管生成长过程中起着重要的作用,EMMPRIN和VEGF-C在乳腺癌的浸润和转移过程中起着协同作用。     

低血压也要防卒中

<正>很多人都知道高血压易引起脑卒中,其实,低血压也可诱发脑血栓形成,引发脑卒中。临床上,低血压导致卒中的病例并不少见。在血压较低时,血液流动慢,会使机体缺血、缺氧,缓慢的血流与血管壁接触时间过长,很容易形成小血栓,一旦聚在一起会堵塞血管,导致缺血性脑卒中。     

扶正祛邪法对甲状腺癌患者术后的临床观察

目的:观察以扶正祛邪法为主治疗甲状腺癌术后的临床疗效。方法:67例甲状腺癌患者,在接受手术、内分泌治疗后给予扶正消瘿汤2个月;治疗前后分别观察患者的甲状腺球蛋白(TG)水平及主要临床证候的变化情况。结果:67例患者TG水平降低率为91.04%,临床症候总有效率达79.10%。结论:甲状腺癌术后辅以中医辨证施治,能够减轻甲状腺癌内分泌治疗副反应,降低血清甲状腺球蛋白水平,改善临床症状,提升患者生活质量。     

Dose optimization of intrathecal administration of human umbilical cord mesenchymal stem cells for the treatment of subacute incomplete spinal cord injury

Human umbilical cord mesenchymal stem cells(hUC-MSCs)are a promising candidate for spinal cord injury(SCI)repair owing to their advantages of low immunogenicity and easy accessibility over other MSC sources.However,modest clinical efficacy hampered the progression of these cells to clinical translation.This discrepancy may be due to many variables,such as cell source,timing of implantation,route of administration,and relevant efficacious cell dose,which are critical factors that affect the efficacy of treatment of patients with SCI.Previously,we have evaluated the safety and efficacy of 4×10⁶ hUC-MSCs/kg in the treatment of subacute SCI by intrathecal implantation in rat models.To search for a more accurate dose range for clinical translation,we compared the effects of three different doses of hUC-MSCs-low(0.25×10⁶ cells/kg),medium(1×10⁶ cells/kg)and high(4×10⁶ cells/kg)-on subacute SCI repair through an elaborate combination of behavioral analyses,anatomical analyses,magnetic resonance imaging-diffusion tensor imaging(MRI-DTI),biotinylated dextran amine(BDA)tracing,electrophysiology,and quantification of mRNA levels of ion channels and neurotransmitter receptors.Our study demonstrated that the medium dose,but not the low dose,is as efficient as the high dose in producing the desired therapeutic outcomes.Furthermore,partial restoration of theγ-aminobutyric acid type A(GABAA)receptor expression by the effective doses indicates that GABAA receptors are possible candidates for therapeutic targeting of dormant relay pathways in injured spinal cord.Overall,this study revealed that intrathecal implantation of 1×10⁶ hUC-MSCs/kg is an alternative approach for treating subacute SCI.
