《医用有机化学》课程中进行德育渗透

教学与德育有机融会贯通,是当前教育领域的共识。医学本科生秉承"以德载医"的精神,肩负"治病救人"的重任,因此德育教育在整个医学教学中占有重要的地位。《医用有机化学》教材中含有丰富的德育内容,高校教师传授专业知识的同时,在教学过程中巧妙的穿插辩证唯物主义、爱国主义和社会责任感的思政教育,可以帮助学生们树立正确的世界观和人生观。文章以医用有机化学课程为例,主要从教师的自身道德素养、德育在教学过程中的具体实践和德育实施过程中需要注意的问题三方面进行阐述,充分将新时代新理念融入大纲、教案和课堂中,化"知识"为"智慧",变"文化"为"品格",充分发挥医用有机化学课程的德育功能。     

米利酮对豚鼠心乳头肌及主动脉条的作用

米利酮是非洋地黄，非儿茶酚胺类强心药，具有明显的正性肌力和扩血管作用。国外用于治疗难治性心衰及洋地黄中毒的心衰病人。本文用豚鼠乳头肌及主动脉条进行实验，结果表明合成与进口米利酮的正性肌力作用效价相同，对抗去甲肾上腺素缩血管的作用也等同。

Uterine lipoleiomyomas: a clinicopathologic study of 50 cases.

Lipoleiomyoma is an uncommon uterine neoplasm and, although presumed to be benign, has been inadequately studied. Confirming the benign nature of this tumor is important because it can closely resemble well-differentiated liposarcoma. We evaluated 50 consecutive lipoleiomyomas diagnosed at the Washington Hospital Center from 1998 to 2004; 2.1% of patients who had uterine leiomyomas during this period had a lipoleiomyoma. The mean and median patient age was 54 and 51 years, respectively. The mean and median tumor size was 4.6 and 2.1 cm, respectively. Forty-three (83%) tumors were located in the uterine corpus, and 7 (13%) were in the cervix. One broad ligament tumor and one retroperitoneal tumor were also studied. The mitotic index was zero for all tumors. No tumors displayed cytological atypia, necrosis, calcification, or other degenerative changes. Follow-up periods ranged from 1.8 to 7.5 years (mean, 5.0 years). Four patients died of unrelated causes. There were no recurrences or fatalities related to tumor. Lipoleiomyoma of the uterus seems to have an uneventful clinical course and can now be confidently regarded as benign.     

短时间高氧对肺泡Ⅱ型上皮细胞线粒体活性氧产生及相关通路的影响

目的探讨短时间高氧对肺泡Ⅱ型上皮细胞（AECⅡ）线粒体Ca²⁺ /烟酰胺腺嘌呤二核苷酸（NAD⁺）/沉默信息调节因子3（SIRT3）/超氧化物歧化酶2（SOD2）通路及活性氧的影响。 方法将RLE-6TN细胞株细胞分为对照组、高氧组及线粒体钙通道拮抗剂组（拮抗剂组）。对照组细胞置于常规细胞培养箱中，高氧组细胞置于氧浓度为90%的培养箱中，拮抗剂组细胞加入钌红（2 μmol / L）后置于氧浓度为90%的培养箱中，各组均持续培养4 h。随后，对各组细胞线粒体内Ca²⁺、活性氧、NAD⁺、还原型烟酰胺腺嘌呤二核苷酸（NADH）含量进行检测，并计算NAD⁺ / NADH比值；同时，采用实时荧光定量PCR检测SIRT3和SOD2信使RNA（mRNA）水平。 结果各组间细胞线粒体内Ca²⁺、活性氧、NAD⁺、NADH、NAD⁺ / NADH比值及SIRT3 mRNA、SOD2 mRNA表达水平的比较，差异均有统计学意义（F = 183.500、135.900、32.140、51.520、128.300、59.970、45.020，P均< 0.001）。且与对照组及拮抗剂组比较，高氧组细胞线粒体内Ca²⁺[（19.5 ± 0.8）、（17.2 ± 0.7）、（24.3 ± 0.3）nmol / L]、活性氧[（491 ± 9）、（480 ± 5）、（530 ± 6）相对荧光单位]及NADH[（0.85 ± 0.03）、（0.87 ± 0.04）、（1.06 ± 0.06）nmol / 10⁴ cells]含量均明显升高，而NAD⁺含量[（3.30 ± 0.12）、（3.24 ± 0.14）、（2.58 ± 0.29）nmol / 10⁴ cells]、NAD⁺ / NADH比值[（3.89 ± 0.15）、（3.71 ± 0.15）、（2.44 ± 0.27）]、SIRT3 mRNA[（1.01 ± 0.11）、（0.96 ± 0.08）、（0.45 ± 0.09）]及SOD2 mRNA[（1.01 ± 0.14）、（1.05 ± 0.11）、（0.48 ± 0.10）]表达水平均显著降低（P均< 0.05）。 结论短时间高氧可通过AECⅡ线粒体内Ca²⁺ / NAD⁺ / SIRT3 / SOD2通路导致活性氧蓄积。     

A novel standardized test system to evaluate dynamic visual acuity post trifocal or monofocal intraocular lens implantation: a multicenter study

ObjectivesTo compare the dynamic visual acuity (DVA) following implantation of trifocal with monofocal intraocular lenses (IOL) and using a novel test system.MethodsThe present research was a retrospective, multicenter clinical study. Two hundred and ten eyes of 149 patients that underwent cataract phacoemulsification and IOL implantation were enrolled. One hundred and ten eyes of patients received trifocal (AT LISA tri839MP, Carl Zeiss Meditec, Germany) and 100 eyes received monofocal (Tecnis ZCB00, Abbott, United States) lenses and were evaluated 3 months after implantation. Outcome measures included monocular uncorrected distance (UDVA), intermediate (UIVA) and near (UNVA) visual acuity and best corrected distance visual acuity (BCDVA; logMAR units); contrast sensitivity under photopic, mesopic, with glare conditions; and dynamic visual acuity using a self-developed system.ResultsThere was no statistically significant difference in baseline characteristics between groups. Monocular UDVA, UIVA, and UNVA were significantly better (all p < 0.001) in the trifocal IOL group, but not BCDVA. The trifocal IOL group showed better contrast sensitivity under photopic, mesopic, with or without glare conditions (p < 0.05) and statistically significantly better dynamic vision at 15, 30, 60, and 90 degrees per second (dps) compared with the monofocal group (all p < 0.001). The strength of positive association only between UIVA and dynamic visual acuity increased as the velocity increased, but not UDVA or UNVA.ConclusionsDiffractive trifocal IOL provides better postoperative full range vision acuity, contrast sensitivity, and dynamic vision compared with monofocal IOLs. And intermediate visual acuity is increasingly associated with DVA as the velocity increasing.Subject terms: Quality of life, Outcomes research
