高危原发前列腺胃肠道外间质瘤诊疗体会及文献复习

目的探讨前列腺原发胃肠道外间质瘤诊治要点。 方法回顾性分析我院2017年9月诊治的1例高危原发性前列腺胃肠道外间质瘤临床病理特征资料、随访情况，总结现有文献讨论总结本病诊治心得。 结果65岁男性，因"前列腺电切术后2年，反复血尿3个月余"入院。术前MRI考虑为来源不清的盆腔巨大实性占位（115 mm×105 mm×85 mm），经直肠穿刺诊断为梭形细胞来源的肿瘤。行盆腔肿瘤切除+膀胱前列腺腺切除+盆腔淋巴结清扫术+Bricker术。术后病理提示为前列腺原发胃肠道外间质瘤[CD117（+）；Dog1（+）；CD34（+）；PSA（+）；AR（+）；P504s（+）；Ki-67（2%）]。术后肿瘤组织全外显子测序提示为C-Kit基因（Exon 11 p.Q556-V560del）存在明显临床意义突变，筛选靶向药物甲磺酸伊马替尼+比卡鲁胺（PSA平稳后停用）口服，术后随访18个月无肿瘤复发及不良并发症。 结论前列腺原发胃肠道外间质瘤罕见，需与前列腺其他良恶性肿瘤相鉴别诊断。全外显子测序了解其发病高危基因，同时筛选药物辅助治疗可使患者生存获益。     

腹腔镜扩大左半肝联合全尾叶切除术

1．肝门处预置肝门阻断带，必要时行肝门阻断控制出血；2.肝脏肿瘤压迫第一、二、三肝门及下腔静脉，紧贴肿瘤包膜处理各管道，采取左右结合、由浅入深的策略；3.优先离断肝实质，劈肝后分离出左侧肝蒂，以直线切割闭合器离断左侧肝蒂；4.肝实质内紧贴包块包膜离断肝实质；5.肝脏包块侵犯肝中静脉及右侧尾状叶，术中联合肝中静脉及全尾叶切除；6.术中避免损伤右侧肝蒂及右肝静脉；7.术中使用超声刀、Ligasure等能量器械断肝、止血；8.缝合技术在腹腔镜肝切除手术中具有重要作用。     

肝细胞癌中miR-942-5p的表达及其与患者恶性特征及不良预后的关系

目的:探讨微小RNA-942-5p(miR-942-5p)在肝细胞癌(HCC)组织中的表达及其功能。方法:用实时定量PCR检测西安交通大学第一附属医院样本库保存的73例HCC组织和对应癌旁组织中miR-942-5p的表达。分析miR-942-5p表达与HCC患者临床病理资料的关系,同时分析TCGA数据库中miR-942-5p表达与HCC患者总生存率的关系。Transwell小室检测干扰miR-942-5p表达后HCC细胞迁移和侵袭能力的变化,StarBase V3.0网站和荧光素酶报告基因质粒预测分析miR-942-5p的下游靶点,并用Western blot验证。结果:miR-942-5p表达量在HCC组织中明显高于对应癌旁组织(2.390 vs. 1.764,P0.05)。miR-942-5p表达量与HCC患者肿瘤数目、血管浸润和临床分期明显有关(均P0.05)。miR-942-5p高表达HCC患者总生存率明显低于miR-942-5p低表达HCC患者(19.535%vs. 53.873%,P0.05)。沉默miR-942-5p表达后,肝癌HCCLM3和MHCC97H细胞迁移和侵袭能力明显减弱(均P0.05)。预测与分析结果显示,扣针蛋白5(FBLN5)是miR-942-5p的直接下游靶点(P0.05),沉默miR-942-5p表达导致HCCLM3和MHCC97H细胞中FBLN5表达增加。结论:miR-942-5p在HCC组织中表达异常升高并与恶性临床特征和不良预后密切相关,机制可能与miR-942-5p抑制FBLN5表达促进HCC细胞迁移和侵袭有关。     

Are plain-language summaries included in published reports of evidence about physiotherapy interventions? Analysis of 4421 randomised trials,systematic reviews and guidelines on the Physiotherapy Evidence Database (PEDro)

BackgroundA plain-language summary is a short and clearly stated version of a study’s results using non-scientific vocabulary that provide many advantages for patients and clinicians in the process of shared decision-making.ObjectivesThe primary objective was to investigate the extent to which published reports of physiotherapy interventions provide plain-language summaries. We investigate as the secondary objectives if the available plain-language summaries are at a suitable reading level for a lay person and if inclusion of plain-language summaries in these reports is increasing over time and is associated with trial quality (i.e. PEDro score).Data sourcesAll 4421 randomised controlled trials (RCT), systematic reviews and clinical practice guidelines that included plain-language summaries indexed on Physiotherapy Evidence Database (PEDro) were included.Main outcome measuresProportion of published reports with plain-language summaries, Flesch Reading Ease Score (FRES) and the Flesch–Kincaid Grade Level (FKGL).ResultsThe number of published reports with a plain-language summary doubled in the last 6 years. From a total of 34,444 reports indexed on PEDro, only 4421 reports had English plain-language summaries. RCTs with plain-language summaries had higher PEDro scores than RCTs without plain-language summaries (mean difference = 0.8 points, 95%CI 0.7 to 0.8). Only 2% of reports were considered at a suitable reading level by the FKGL formula and 0.1% by the FRES formula.ConclusionsAlthough the publication of plain-language summaries is increasing over time, the current number corresponds to only 13% of all published reports. In addition the majority of plain-language summaries are written at an advanced reading level.     

Parental Guidance and Children’s Healthy Food Consumption: Integrating the Theory of Planned Behavior with Interpersonal Communication Antecedents

The study of parenting practices on child food consumption has often been characterized as having great utility but lacking in theory. In contrast, the theory of planned behavior (TPB) has often been suggested to be limited in its utility. To address these gaps, interpersonal constructs – the concepts of active parental guidance (e.g., nutrition education) and restrictive parental guidance (e.g., rule-setting) – were integrated as antecedents to the original TPB variables in predicting child fruits and vegetables (FV) consumption. We surveyed 210 child/adolescent participants, aged between 10 and 16 in Singapore. Results from structural equation modeling showed that the integrative TPB model displayed an acceptable fit. Parental active guidance was associated with all three proximal predictors of behavior. Our results suggest that there are promising contributions to the theory of planned behavior in predicting child food consumption behavior by considering interpersonal antecedents.
