腹腔镜辅助保留幽门胃切除术改善早期胃癌术后胆汁反流性胃炎前瞻性随机对照研究

目的比较腹腔镜辅助保留幽门胃切除术(LAPPG)与腹腔镜辅助远端胃大部切除术(LADG)(BillrothⅠ式吻合)对胃体中部早期胃癌病人术后继发性胆汁反流性胃炎(BRG)的影响。方法自2018年2月至2018年12月,对上海交通大学医学院附属仁济医院胃肠外科收治的69例早期胃体中部癌(cT1N0M0)病人进行1∶1前瞻性随机化入组,其中LAPPG组(行LAPPG)34例,LADG组(行LADG,BillrothⅠ式吻合)35例,进行6个月随访,比较两组术前、术中、术后及随访结果。结果两组病人在年龄、性别、BMI、术前合并症及术后病理诊断的基线水平差异无统计学意义(P>0.05)。两组淋巴结清扫数目、手术时间、术中出血量、术后首次排气时间、胃管拔除时间、Ⅱ级以上并发症差异无统计学意义(P>0.05)。术后6个月随访结果显示,BRG临床表现无特异性,在两组中差异无统计学意义(P>0.05);但内镜下诊断BRG比例LAPPG组显著低于LADG组,差异有统计学意义[3例(8.8%)vs.16例(45.7%),χ^2=11.763,P=0.001];LAPPG组中Kellosalofen分级Ⅱ度以上BRG的比例显著低于LADG组,差异有统计学意义[2例(5.7%)vs.9例(25.7%),χ^2=5.062,P=0.024];组织学活检发现LADG组胃小凹增生1例、腺体萎缩伴肠化3例,LAPPG组未观察到上述病理组织学异常,但两组差异无统计学意义(P>0.05)。结论LAPPG治疗早期胃体中部癌安全可行,该术式较LADG可改善术后BRG的发生率及严重程度。其对病人术后长期疗效及残胃癌发生率的影响仍有待大样本RCT研究的长期随访证实。

目的在治疗心脑血管疾病方面,评价葛根素注射液与发热反应的相关性。方法计算机检索Cochrane Central Register of Controlled Trials、EMbase、Pubmed、CBM、WanFang Data和CNKI（至2013年8月）中有关葛根素注射液与发热相关性的临床试验,并手工检索相关研究及其参考文献。根据纳入和排除标准选择纳入文献、提取资料和进行方法学质量评价。在此基础上,以不良反应发生率为指标,利用系统评价的方法考察葛根素注射液与发热的相关性。结果依据纳入排除标准共纳入8项随机对照临床研究。结果显示,葛根素注射液组整体的不良反应发生率为1．20％,提示发热为葛根素注射液的常见不良反应。进一步的亚组分析结果显示,天保康葛根素注射液未见发热反应;普润葛根素注射液的发热反应发生率为0．90％,为偶见不良反应;其他产家的葛根素注射液的发热反应发生率为5．13％,为常见不良反应。葛根素注射液的发热反应发生率从2005年之前的4．04％降至2005年之后的0．32％。结论发热为葛根素注射液不良反应,除药物本身因素外,该不良反应与葛根素注射液的制备工艺具有一定的相关性。     

Maternal humoral factors associated with perinatal human immunodeficiency virus type-1 transmission in a cohort from Kigali, Rwanda, 1988-1994

OBJECTIVES: to study different parameters of humoral immunity responses in the serum of 39 human immunodeficiency virus type-1 infected pregnant women from Kigali, (Rwanda) in correlation with perinatal transmission. METHODS: this study was done between 1988 and 1994. Thirty nine HIV-1 infected women, 18 transmitting (T) and 21 non-transmitting (NT) mothers, have been chosen based on the quantity of sera available for analysis. Maternal data were collected at the time of delivery or during the preceding month. Quantification of viral load was performed by the signal amplification bDNA assay. Specific reactivity of antibody was tested against recombinant p24 protein and five different synthetic peptides from gp120 and gp41 based on HIV LAI-strain sequences. Neutralization assays were performed against laboratory (RII strain of the HIV-1 C subtype) and primary strains (two NSI and one SI of the HIV-1 A subtype). Antibody Dependent Cellular Cytotoxicity assay was performed with CEM.NK(R) cells against a laboratory HIV-1 strain. RESULTS: absence of correlation regarding maternal viral load, or viral subtype and vertical transmission was observed. By contrast, the CD4/CD8 ratio was significantly higher in non-transmitting mothers compared to transmitting mothers. Moreover, high anti-p24 antibody avidity was correlated with a lower risk of perinatal transmission. Furthermore, transmission risk appeared significantly higher with reactivity of serum samples to linear epitopes of gp41 (amino acids 566-582, 578-594), whereas risk appeared lower with reactivity to the immunodominant domain of gp41 (amino acids 597-609). No significant difference was observed in titres of antibody neutralizing primary isolates (two NSI (non syncitium inducer) and one SI (syncitium inducer) of the HIV-1 A subtype) and laboratory strain (RII strain, of the HIV-1 C subtype) between transmitting and non-transmitting mother's sera. In addition, titres of Antibody Dependent Cellular Cytotoxicity were similar in transmitting versus non-transmitting mothers. However, high Antibody Dependent Cellular Cytotoxicity titres were correlated with a good clinical status of children. CONCLUSIONS: three parameters such as high CD4/CD8 ratio, high anti-p24 antibody avidity and high reactivity against the immunodominant epitope of gp41 have been shown to be correlated with no perinatal transmission. High Antibody Dependent Cellular Cytotoxicity titres appeared to be linked to a good clinical status of children after birth. One parameter, reactivity against two linear epitopes of gp41, appeared to be correlated with vertical transmission.
