甲状腺乳头状癌前上纵隔淋巴结转移临床病理特征初步分析

目的 探讨肿瘤位置、最大直径及甲状腺外浸等临床病理特征与甲状腺癌前上纵隔淋巴结转移的关系。 方法 研究分析初次手术治疗的60例甲状腺乳头状癌患者临床及病理资料,运用检验临床病理特征与前上纵隔淋巴结阳性率的相关性。 结果 肿块位置、最大直径、数量、腺体外侵、受累腺叶数及Ⅵ区淋巴结转移等特征,以及患者年龄等相关因素中,只有VI区淋巴结对前上纵隔淋巴结状态有影响;60例患者前上纵隔淋巴结转移率为10/60(16.67%)。相关因素的前上纵隔淋巴结转移率对比:≥55岁vs <55岁(20% vs 16.36%, P<0.05);肿块位于下极 vs 上极 vs 中极(P>0.05);最大直径≥1.5 cm vs 最大直径<1.5 cm(18.18% vs 15.79, P>0.05);单灶 vs 多灶(21.88% vs 10.71%, P>0.05);单叶 vs 多叶(17.5% vs 15%, P>0.05);男性vs女性(20% vs 15.55%, P>0.05); Ⅵ区淋巴结阳性vs 阴性(24.43% vs 3.57%, P<0.05); 结论 总体来说,甲状腺乳头状癌前上纵隔淋巴结转移率较低。本研究发现VI区淋巴结状态可能与前上纵隔淋巴结转移相关,未来仍需大样本前瞻性的研究验证。     

慕课在我国高等医学教育中应用的文献计量分析

目的　探讨慕课在我国高等医学教育领域的应用现状和发展趋势，为本领域今后的研究提供参考。方法　检索中国知网、万方数据服务平台、维普数据库、中国生物医学文献数据库建库以来至2020年3月1日收录的相关文献，运用文献计量学方法对年发文量、期刊分布、基金支持、著者分布、被引频次、文献类型和高频关键词进行统计分析。将导出的资料用Excel 2010建立数据库，借助频数分析法进行描述性统计。结果　纳入文献754篇，分别收录于262种期刊；以医学教育类期刊为主；基金资助率达50%；黄坪、张欣、李鑫辉等7人为核心作者；以人体解剖学为代表的基础医学类课程应用研究最多；慕课应用研究以理论课程为主；课程评价包括终末性评价、形成性评价、平台考核、综合能力和自主学习能力５大方面；研究热点为基于慕课的混合式教学模式及其在护理教育、中医教育及继续医学教育中的应用。结论　近5年，慕课在我国高等医学教育中发展迅速，核心作者已形成，但缺乏深度合作。未来应增加实验（训）类课程的应用研究，同时应进一步完善实验性研究的设计及课程评价体系。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.     

舶来的"四泉利润"

“做个加盟店很不划算，交加盟费、风险金，还要给特许商管理费……”，许多意向加盟商都有这种说法。有些特许商也常说：“开上几十家店，加盟费都赚不过来，自已还可以直营，还有管理费、促销费、培训费……”这正应了“羊毛出在羊身上”这句古话。
