分析了颗粒级配对水泥基胶凝材料结构与性能的影响。采用立磨终粉磨工艺和球磨工艺制备的水泥,对水泥颗粒分布、工作性能以及水泥混凝土的耐久性进行了研究与分析。结果表明:水泥均匀性系数与标准稠度用水量相关性很好,呈正相关关系;n值越大,水泥颗粒分布越窄,其制备的混凝土抗碳化能力、耐磨性和收缩性越差;在严格控制好n值条件下,立磨终粉磨技术生产的水泥所制备的混凝土力学性能和耐久性良好,值得深入研发和推广,并提出改进措施。

Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.

背景胃癌新辅助化疗是胃癌综合治疗的重要内容,取得了很好的结果,但是仍然有部分患者在治疗期间疾病进展,失去治疗机会。寻找能够预测新辅助化疗疗效的指标是今后研究的热点。目的探讨以铂类为基础的新辅助化疗疗效与胃癌临床病理特征及泛素特异性蛋白酶39(USP39)的相关性。方法选取2012—2013年在中国人民解放军总医院进行以铂类为基础的新辅助化疗的胃癌患者44例为研究对象,采用以铂类为基础的新辅助化疗SOX方案进行治疗,根据治疗效果分为有效组和无效组。收集患者的临床病理资料,采用免疫组织化学及Western blotting法检测USP39的表达。结果 44例患者采用以铂类为基础的新辅助化疗SOX方案,其中有效组23例,无效组21例。有效组与无效组患者性别、年龄、病程、血红蛋白、中性粒细胞分数(n)、淋巴细胞分数(L)、血清清蛋白水平及肿瘤部位、肿瘤大小、分化程度、术前化疗疗程比较,差异均无统计学意义(P>0.05)。无效组患者n/L≥3及USP39阳性率高于有效组(Pn/L、USP39低于无效组,n/L、USP39有可能成为预测胃癌以铂类为基础的新辅助化疗疗效的有效分子。

Objective: The role of anesthesia in maternal mortality is unknown in the Democratic Republic of Congo (DRC). This study was conducted with the objective of analyzing the determinants of morbidity and maternal mortality linked to anesthesia in course of cesarean section. Methods: This is a prospective, analytical and mono-centric study carried out on women who underwent cesarean section at the Centre Hospitalier Mère-Enfant Monkole from January 1st, 2011 to December 31st, 2018. The variables analyzed were socio-demographic, clinical, biological and anesthetic as well as the maternal issues. Data analysis was performed with SPSS 21.0 software. The determinants of mortality were sought by logistic regression with p Results: During this period, 1954 cesarean sections were performed. The mean age of the women was 31 years (range 14 to 47), 1549 women (79.3%) had completed prenatal consultation in Monkole and 405 (20.7%) elsewhere. The emergency was extreme in 192 cases (9.82%), absolute in 445 (22.77%) and relative in 1317 (67.4%). Locoregional anesthesia (LRA) was performed in 1811 cases (92.68%). The main complications were marked by arterial hypotension (22.9%) due to spinal anesthesia, and mortality was 0.56%. In multivariate analysis, only extreme emergency (aOR 7.62 95% CI: 2.80 - 71.23 p = 0.007), coma on admission (aOR 10.44 95% CI: 1.81 - 60.13 p = 0.009), general anesthesia (aOR 15.41 95% CI: 2.11 - 40.21 p = 0.007) and intraoperative transfusion due to anemia/hemorrhage (aOR 8.63 95% CI: 1.07 - 69.55 p = 0.043) persisted as determinants of maternal death. Conclusion: Maternal mortality (0.56%) in this series was relatively low for a low-income country and no death was directly related to anesthesia. General anesthesia, extreme urgency, intraoperative transfusion due to anemia/bleeding, and coma on admission were the major determinants of mortality.
