全腹腔镜、腹腔镜辅助与开腹胃癌根治术治疗Ⅱ、Ⅲ期胃癌的疗效对比

目的探讨全腹腔镜胃癌根治术（TLG）、腹腔镜辅助胃癌根治术（LAG）与传统开腹术（TOS）对Ⅱ、Ⅲ期胃癌的近期及远期疗效。 方法回顾性分析2013年1月至2016年6月陕西中医药大学附属医院行胃癌根治术的患者共136例，根据患者手术方式的不同分为TLG组（45例），LAG组（40例），TOS组（51例）。观察和比较3组患者手术时间、出血量、淋巴结清扫数、术后排气时间、住院时间、术后并发症发生情况，采用Kaplan-Meier法对患者术后5年远期疗效进行生存分析。 结果TLG组患者出血量、排气时间及住院时间低于TOS组及LAG组，LAG组患者手术时间高于TLG组及TOS组，差异均有统计学意义（P<0.05）；3组患者术后并发症发生率比较，差异无统计学意义。共129例获得随访，其中TLG组失访2例，LAG组2例，TOS组3例。TLG、LAG、TOS组平均无瘤生存时间为（53.4±2.1）个月（95%CI=50.45~58.22个月）、（54.3±2.0）个月（95%CI= 47.99~56.18个月）、（52.3±2.1）个月（95%CI=50.98~55.65个月），3组患者无瘤生存时间比较，差异无统计学意义（F=0.519，P=0.772）。 结论TLG术能够在保证患者术后疗效的同时，降低患者术中出血量、排气时间及术后住院时间，TLG术治疗Ⅱ、Ⅲ期胃癌安全可行，疗效显著，值得推广。     

Research campaigns in the UK National Health Service: patient recruitment and questions of valuation

The National Institute for Health Research (NIHR) aims to improve national ‘health and wealth' by providing infrastructural support to enable clinical research in National Health Service settings in England and Wales. Cognisant of the consequences of studies' failure to achieve required numbers of participants, it also actively campaigns to promote patient awareness of research, and willingness to participate in trials. In this paper, we analyse recent NIHR campaigns and policies designed to encourage patients to participate in clinical research to interrogate how they are implicated in the national bioeconomy. In doing so we expand the notion of ‘clinical labour' to include the work of patient recruitment and highlight an emergent obligation on patients to contribute to research processes. Whereas once patient knowledge and experience may have been devalued, here we draw on the concept of ‘assetisation' (Birch 2012) to explore the emergent relationship between healthcare system and patient as research participant. We consider how patients' contribution goes beyond the provision of standardised objects of valuation so that patients themselves may be perceived as assets to, not only recipients of, the national healthcare system.     

Rupture Resolution Rating System (3RS): Development and validation

Objective: Our aim was to examine the reliability and validity of the Rupture Resolution Rating System (3RS), an observer-based measure of alliance ruptures and resolution processes. Method: We used the 3RS to rate early sessions from 42 cases of cognitive behavior therapy. We compared the 3RS to a simplified version of the Structural Analysis of Social Behavior (SASB), as well as patient and therapist self-reports of ruptures and the alliance. Results: Coders achieved high rates of interrater reliability on the frequency of confrontation and withdrawal ruptures and resolution strategies (ICCs?=?.85 to .98), as well as ratings of the therapist’s contribution to ruptures and the extent to which ruptures were resolved (ICC?=?.92). Predictive validity analyses found that confrontation markers (d?=?.74), successful resolution (d?=?.67), and ratings of the therapist’s contribution to ruptures (d?=?.61) predicted dropout from therapy. Analyses of convergent validity with the SASB failed to meet predictions; however, we observed theoretically coherent relations between 3RS and SASB variables. Confrontation rupture markers were significantly associated with patient self-report of rupture (d?=?1.54) and therapist self-reported alliance (r?=??.50, p?=?.002). Conclusions: This study provides evidence that the 3RS is a reliable and useful tool for examining psychotherapy process and predicting dropout.

Clinical or methodological significance of this article: This study provides evidence of the reliability and validity of the 3RS, an observer-based measure of alliance ruptures and resolution processes. The 3RS can be used to identify problems in the therapeutic relationship that are associated with premature dropout from therapy.     

The importance of how research participants think they are perceived: results from an electronic monitoring study of antiretroviral therapy in Uganda

Novel monitoring technologies in HIV research, such as electronic adherence monitors (EAMs), have changed the nature of researcher-participant interactions. Yet little is known about how EAMs and the resulting interaction between researchers and participants affect research participation and the data gathered. We interviewed participants and research assistants (RAs) in an observational cohort study involving EAMs for HIV antiretroviral therapy (ART) in Uganda. We qualitatively explored interviewees’ views about ethical issues surrounding EAMs and assessed data with conventional and directed content analysis. Participants valued their relationships with RAs and were preoccupied with RAs’ perceptions of them. Participants were pleased when the EAM revealed regular adherence, and annoyed when it revealed non-adherence that contradicted self-reported pill-taking behavior. For many, the desire to maintain a good impression incentivized adherence. But some sought to creatively conceal non-adherence, or refused to use the EAM to avoid revealing non-adherence to RAs. These findings show that participants’ perceptions of the study staff's perceptions of them affected the experience of being monitored, study participation, and ultimately the data gathered in the study. Investigators in monitoring-based research should be aware that social interactions between participants and study staff could affect both the practical and ethical conduct of that research.     

中药复方配伍的研究方法及其进展

中药复方是由2味或2味以上中药遵循中医理论组合而成的方剂。多味中药在合适的剂量配比之下,协同发挥作用,实现中医的整体调节治疗。研究中药复方的配伍对推动中药现代化发展、新药开发以及临床应用有着重要意义。近年来,研究者们在传统的"七情和合"与"君臣佐使"的基础上,运用新技术和新方法对中药复方的成分、药效活性和药代动力学性质等进行了研究,从不同角度探讨了中药复方配伍的科学内涵。同时,多种数理方法和模型的建立、网络药理学和数据挖掘方法的发展与应用,也对中药复方配伍研究提供了很大帮助。研究方法的发展虽促进了中药复方配伍的科学研究,但还需进一步建立适合中药复方配伍复杂关系的研究方法,以阐明中药复方及其成分/组分配伍的内在规律,进而构建新的现代中药复方,这也是目前中药复方配伍研究的重点任务。
