指压天枢穴加腹部按摩联合番泻叶在静脉肾盂造影患者中的应用效果

目的探讨指压天枢穴加腹部按摩联合番泻叶在静脉肾盂造影患者中的应用效果。方法选取我院2018年12月至2019年8月期间行静脉肾盂造影的120例患者,随机分为两组各60例。对照组给予番泻叶,观察组给予天枢穴指压加腹部按摩联合番泻叶,比较两组的肠道清洁力度和不良反应情况。结果治疗后,观察组的肠道清洁力度明显高于对照组(P <0.05);观察组的不良反应发生率为6.67%,明显低于对照组的23.33%(P <0.05)。结论静脉肾盂造影患者采用指压天枢穴加腹部按摩联合番泻叶的效果较好,可提高肠道清洁力度,降低不良反应发生率。     

针刺京骨穴联合推拿治疗背肌筋膜炎临床研究

目的探讨针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效。方法将2016年10月—2018年10月收治的背肌筋膜炎患者86例纳入研究,采用随机数字表法分组。对照组43例予以推拿治疗,观察组43例予以针刺京骨穴联合推拿治疗。比较2组患者的治疗总有效率、VAS评分及Oswestry功能障碍指数、痊愈所用时间。结果观察组治疗总有效率为95.3%,而对照组仅为81.4%,差异有统计学意义(P<0.05);2组治疗后VAS评分、Oswestry功能障碍指数均有下降,观察组上述指标低于对照组,差异有统计学意义(P<0.05);观察组痊愈所用时间短于对照组,差异有统计学意义(P<0.05)。结论针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效突出,可缓解背部疼痛、恢复功能活动,并缩短了愈合时间,提高了生活质量,值得一定的临床推广。     

包含颈外静脉的颈阔肌肌皮瓣修复口腔癌切除后缺损

目的探讨将颈外静脉包含在颈阔肌肌皮瓣内修复口腔癌切除后缺损的手术方法。方法先形成蒂在颌缘下包含颈外静脉的颈阔肌肌皮瓣，待口腔肿瘤切除后，将肌皮瓣经口底隧道引入口腔修复缺损。结果临床应用17例，肌皮瓣均无血运障碍，100％存活，其中有2例发生口面痿，经换药后痿口完全闭合。结论将颈外静脉包含在颈阔肌肌皮瓣内有助于肌皮瓣血循环的改善和存活率的提高。     

口腔鳞状细胞癌颈淋巴转移范围和临床病理因素间的相关性研究

目的探讨口腔鳞状细胞癌颈淋巴转移范围和临床病理因素间的关系。方法对26例已存在颈淋巴转移的原发口腔癌患者，进行颈淋巴转移范围和患者的临床病理资料的统计分析，寻找影响转移范围的主要因素。结果单因素分析发现，肿瘤生长方式和分化程度与转移范围相关。多因素分析显示，肿瘤生长方式(浸润型)和肿瘤转移范围相关。结论对颈淋巴已有转移的口腔癌患者，若原发灶为浸润性生长，肿瘤倾向于更大范围的转移。对已有颈淋巴转移的口腔癌患者，颈淋巴清扫术范围的制定，主要考虑肿瘤生长方式，适当考虑肿瘤发病部位、厚度、大小和细胞的分化程度，可以不考虑患者年龄和性别。     

Oral administration of methylergometrine shows a late and unpredictable effect on the non-pregnant human menstruating uterus

Objective: To study the pharmacodynamic and pharmacokinetic properties of oral and intravenous methylergometrine upon uterine motility during menstruation. Study-design: Intra-uterine pressure was measured in six volunteers with a fluid-filled sponge-tipped catheter during menstruation. Methylergometrine was given orally (0.5 mg) or intravenously (0.2 mg) in a cross-over design. Results: After intravenous administration, a fast increase of the frequency of uterine contractions and basal tone occurred with a decrease of amplitude, lasting at least 30 min. Oral administration had a late and less marked effect on uterine motility. An intravenous dose administered 24 h after an oral dose had no effect on uterine motility. Pharmacokinetic data, such as the maximum plasma concentration (C_max), the time at which C_max is reached (t_max) and the half-life of absorption (t_1/2abs) also demonstrated large individual variations after oral administration. Conclusion: Oral administration of methylergometrine had an unpredictable and late effect on uterine motility on the menstruating uterus, probably due to an unpredictable bioavailability, in contrast with the fast and predictable effect after intravenous administration.     

低抗凝肝素来源低分子肝素口服制剂的研究

以生产肝素的副产品——低抗凝肝素为原料,采用亚硝酸控制解聚法制得了低分子肝素,分子量为5300,抗凝活性为39.2u/mg,测定了理化指标。以对家兔实验性血栓形成的影响为药效学指标,确定低分子肝素口服制剂的处方组成为低分子肝素、油酸、牛胆盐。研究了所制备的低分子肝素胶囊对家兔血液流变学及血栓形成的影响,并试用于部分动脉粥样硬化症志愿者,表明该胶囊可有效地改善家免和动脉粥样硬化症志愿者血液流变性质,抑制血栓形成。     

Oral tolerance in EAE: reversal of tolerance by T helper cell cytokines

Oral administration of myelin basic protein (MBP) inhibits clinical and histopathological manifestations of experimental autoimmune encephalomyelitis (EAE), but only partially reduces serum anti-MBP antibody titers. We report here that orally administered MBP alters the isotypic distribution of anti-MBP antibody-forming cells (AFC) among various lymphoid tissues, with the most profound differences seen in mucosal tissues. We observed an isotype-selective reduction in anti-MBP IgA but not IgM AFC frequencies in Peyer's patches. The anti-MBP IgA AFC frequencies could be reconstituted by addition of interleukin 4 (IL-4) and interleukin 5 (IL-5). The cytokines did not appear to generate de novo responses since no increases in anti-MBP IgA AFC frequencies were observed in control cultures. These results indicate that decreased antibody production, as a result of oral antigen administration, can be reversed by exposure to the appropriate cytokines.     

肛周按揉及温水足浴对腹部手术后患者肛门排气时间的影响

目的探讨肛周按揉及温水足浴对腹部手术后患者肛门排气时间的影响。方法选择普外科180例腹部手术后患者，随机分为A组（肛周按揉＋温水足浴组＋常规护理）90例和B组（常规护理组）90例。比较2组肛门排气时间及腹胀情况。结果首次肛门排气时间A组早于B组，2组比较差异有统计学意义（P＜0．01）；腹胀症状A组较B组轻。结论肛周按揉结合温水足浴可显著缩短腹部手术术后患者肛门排气时间，减轻术后腹胀症状。
