责任指数对口腔医学专业学生职业精神考核的设想

医学生的责任心体现在其一定行为表现上，是医学生职业精神培养的重要内涵，因此对影响医学生责任心的负向行为进行一定的干预具有重要意义。分析国内外医学院校应用责任指数考核在医学生行为督导养成的评价研究，遵循我国口腔医学专业人才培养的规律，结合口腔医学生成长的特点，借鉴职业精神考核的相关指标——责任指数考核法，试设计口腔医学生行为责任指数测评方案，并预设可行性，为拓宽口腔医学生职业精神的培养提供思路。     

PBL教学法在核医学课间实习教学中的应用研究

目的 通过与LBL教学法对比,探讨PBL教学法在核医学科课间实习教学中的应用效果.方法 选取哈尔滨医科大学2016级临床医学专业本科二班学生72人,随机分为实验组和对照组,每组各36人,在课间实习教学中分别实施PBL教学法和LBL教学法.实习结束后,通过考试及问卷调查,进行教学法评价.结果 观察组在考试成绩、学习兴趣、学习热情、教学满意度、培养临床思维、增强知识点掌握等教学法评价指标均优于对照组,具有统计学意义(P<0.05).结论 与LBL教学法相比,PBL教学法应用于核医学科课间实习教学中更能激发学生学习兴趣、增强综合素质,从而提高教学效果.     

关于医学教育专业人才培养方案修订的几点思考

随着“健康中国”战略的实施，需要建立与之相匹配的“新医科”人才培养体系，“基于医疗卫生系统的需求，以职业胜任力为导向”的教育教学改革势在必行。因此修订人才培养方案时要以胜任力为目标驱动重新梳理培养目标和毕业要求；采用“课程矩阵”设计法，反向设计、正向施工的原则优化课程体系；根据课程目标凝炼课程内容、精炼核心课程；充分利用网络开放课程资源，选修课分模块化设置；通过多种形式将创新创业教育贯穿人才培养全过程。     

Is Atrial Fibrillation a Risk Factor for Gastroesophageal Reflux Disease Occurrence?

Recent studies have reported an association between gastroesophageal reflux disease (GERD) and atrial fibrillation (AF). The objective of the present study was to evaluate whether AF is one of the risk factors for GERD occurrence.In this hospital-based, retrospective, case–control study, the patients were classified into 2 groups. The patients diagnosed with new AF were assigned to the AF group (n = 1612); those diagnosed without AF and GERD were assigned to the control group (n = 1612). The subjects in the control group were selected from outpatients of total healthcare center without a history of AF or GERD, and matched for age and gender. We evaluated the incidence of GERD and risk factors for GERD occurrence between the 2 groups.The number of patients experiencing occurrence of GERD during the follow-up period was significantly higher in the AF group than those in the control group, respectively (129 patients vs 98 subjects, P = 0.037). The incidence of GERD was significantly higher in the AF group than in the control group by Kaplan–Meier analysis with log-rank test (P = 0.008). The AF group''s adjusted hazard ratio of GERD occurrence against that of the control group was 1.37 (95% confidence interval [CI]: 1.16–1.57; P = 0.009) according to Cox''s proportional hazard model.The presence of AF appears to increase the incidence of GERD and may be considered a risk factor for the development of GERD. Further, large prospective and cohort studies will be required to better establish the correlation of GERD with AF.     

针刺辅助治疗难治性肠易激综合征临床试验方案关键点设计的思考＊

肠易激综合征（Irritable bowel syndrome，IBS）是临床常见病、多发病，其治疗方法丰富，但部分患者疗效欠佳，发展成难治性IBS。目前国内外关于针灸治疗难治性IBS的临床随机对照试验尚不多见。本文立足试验方案设计的“PICOS”原则，从研究对象及诊断标准、干预措施、对照措施、结局指标四个方面入手，重点探讨针刺辅助治疗难治性肠易激综合征临床试验设计的关键要点。从选择特色优势病种、明确诊断标准、制定符合临床实际的干预方案、运用符合目标的安慰针刺、结合研究设计和目的选定结局指标几个角度，阐述试验相关环节设计的原因和思考。     

Intravenous Thrombolysis Is Safe and Effective for the Cryptogenic Stroke in China: Data From the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China)

Background

The intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) therapy is safe and efficient during the treatment of acute ischemic stroke. Nonetheless, the different outcomes among various stroke subgroups have limited data with regard to the safety and efficacy of cryptogenic stroke (CS). The present study compared the safety and efficacy when IVT with rt-PA was used for the treatment of CS and the other stroke subtypes.

关节镜下TightRope治疗后交叉韧带撕脱骨折

目的探讨关节镜下使用TightRope治疗后交叉韧带(PCL)撕脱骨折的技术应用和临床疗效。方法 12例膝关节PCL撕脱骨折患者在关节镜下使用TightRope固定PCL撕脱骨块。术后1周开始在支具保护下被动活动膝关节,术后10个月评估膝关节功能恢复情况。结果 12例患者均获随访,时间10～14个月,平均12.6个月,骨折均Ⅰ期愈合。1例屈膝受限15°,无伸膝受限;2例后抽屉试验(+)。Lysholm膝关节功能评分术前(45.6±6.3)分,术后10个月(87.8±4.8)分,差异有统计学意义(P 0.05)。结论关节镜下使用TightRope治疗PCL撕脱骨折固定可靠,操作相对简单,疗效满意。     

Association of genetic variants at MYP10 and MYP15 with high myopia in a Han Chinese population

Background: Previous genome-wide association study (GWAS) has revealed the association between MYP10 at 8p23 and MYP15 at 10q21.1 and high myopia (HM) in a French population. This study is managed to discover the connection between some single nucleotide polymorphism (located at MYP10 and MYP15) and Han Chinese HM.

Methods and Results: This case-control association study contained 1673 samples, including 869 ophthalmic patients and 804 controls. Twelve tag SNPs have been selected from the MYP10 and MYP15 loci and genotyped by SNaPshot method. Among 12 SNPs, rs4840437 and rs6989782 in TNKS gene were found significant association with HM. Carriers of rs4840437G allele and rs4840437GG genotype created a low risk of high myopia (P = .036, OR = 0.81, 95%CI = 0.71–0.93; P = .016, OR = 0.73, 95%CI = 0.56–0.96; respectively). Carriers of rs6989782T allele and rs6989782TT+CT genotype also had a decreased risk of high myopia (P = .048, OR = 0.82, 95%CI = 0.71–0.94; P = .006, OR = 0.74, 95%CI = 0.59–0.92; respectively). Other 10 SNPs displaced nonsignificant association with HM. Additionally, the risk haplotype AC and the protective haplotype GT, generated by two SNPs in TNKS, were considerably more likely to be association with HM (for AC, P = .002 and OR = 1.26; for GT, P = .027 and OR = 0.84).

Conclusions: Our results demonstrated that some heritable variants in the TNKS gene are associated with HM in the Han population. The possible functions of TNKS in the development and pathogenesis of hereditary high myopia still require further researches to identify.
