重组人粒细胞集落刺激因子对辐射诱发细胞恶性转化的影响

目的研究重组人粒细胞集落刺激因子(granulocyte colony-stimulatingfactor,G-CSF)对60Coγ射线诱发Wistar大鼠肺成纤维细胞恶性转化过程的影响。方法采用噻唑蓝(MTT)比色法、软琼脂克隆培养、流式细胞术(FCM)同时观察正常Wistar大鼠肺细胞、60Coγ射线照射细胞、经G-CSF预处理后60Coγ射线照射细胞、60Coγ射线照射后G-CSF持续处理细胞的增殖活性,克隆形成率和细胞周期的变化。结果G-CSF有抑制单纯照射细胞增殖的作用,使软琼脂克隆形成延迟,使进入细胞周期的细胞减少,细胞周期进程减慢。结论G-CSF能减缓细胞的恶性转化过程。     

安神调经针法治疗月经后期探析

心身疾病是当今医学亟待解决的课题.临床上大量月经后期的患者其发病与心理社会因素密切相关,属心身疾病的范畴.据此,笔者提出了月经调节的中医"心脑-肾气-天癸-冲任-胞宫轴"的新模式,并认为它与现代医学"大脑皮层-下丘脑-垂体-卵巢-子宫生殖轴"的神经内分泌调节系统极为相似.在此基础上创立了一套安神调经疗法.通过调整心脑功能,从而调节下丘脑-垂体-性腺轴,促进卵泡发育,治疗月经后期.并以此为突破点,为心身疾病引起的各种妇科病的针灸治疗提供了一种新方法、新思路.

Appreciative Inquiry as an intervention to change nursing practice in in-patient settings: An integrative review

BackgroundHigh profile accounts of failures in patient care reflect an urgent need for transformational development in healthcare. Appreciative Inquiry is promoted as an approach to exploring and bringing about change in social systems. Appreciative Inquiry has been used extensively in North American business since the late 1980s. The application of Appreciative Inquiry may have merit in the complex world of human health experiences.ObjectivesTo identify, evaluate and synthesise the evidence about the impact of Appreciative Inquiry on changing clinical nursing practice in in-patient settings.DesignAn integrative review and narrative synthesis.SettingIn-patient settings including paediatrics, maternity and mental health.ParticipantsNurses of all grades, patients, carers, relatives, other healthcare professionals including allied healthcare staff, management and students.Data sourcesAn electronic search of the following electronic databases was performed in January 2015 and updated in July 2015: MEDLINE, EMBASE, Cochrane Library (Cochrane database of systematic reviews), Cumulative Index of Nursing and Allied Health Literature, PsychINFO, PsychARTICLES, Amed, Assia, Scopus and Web of Science. Hand searching of reference lists of included studies was undertaken. Limits were set to include literature published in English only and publications from 1990 to July 2015.Review methodsThree reviewers independently assessed eligibility for inclusion and extracted data. Full text articles were systematically appraised using a standardised data extraction instrument in conjunction with criteria to assess whether change using Appreciative Inquiry is transformational.ResultsEight studies (reported in 11 papers) met the inclusion criteria. Overall, these studies demonstrate poor application of Appreciative Inquiry criteria in a nursing context. This makes judgement of the impact difficult. One study achieved transformation against agreed criteria for Appreciative Inquiry. Other included studies demonstrated that Appreciative Inquiry is being perceived as a gateway to knowledge translation rather than transformative change in practice.ConclusionsAppreciative Inquiry offers potential for nurse practice development and change but not without cognisance of the pivotal components. If Appreciative Inquiry is to be perceived as a legitimate research endeavour, there must be engagement and attention to rigour. Findings suggest caution is required against the choreography of Appreciative Inquiry where participant experiences are moulded to fit a previously drafted master plan. Further research is needed to explore the role of expert facilitation in securing and sustaining successful outcomes of Appreciative Inquiry.     

A comparison between Qigong exercise and cycle ergometer exercise for the rehabilitation of chronic obstructive pulmonary disease: A pilot randomized controlled trial (CONSORT)

Background:Chronic obstructive pulmonary disease (COPD) is a common respiratory disease that is associated with significant morbidity and mortality. Exercise training confers health benefits to people with COPD. The purpose of this study was to compare differences in the rehabilitation of COPD between Qigong exercise (QE) and aerobic exercise using a cycle ergometer (CE).Methods:This study was a randomized single-blind controlled trial. Twenty six participants were recruited and randomized to either the Qigong group or the cycle ergometer group. Both interventions lasted 12 weeks and comprised a 30 minutes supervised training session performed twice a week, that is, 24 sessions in total. The primary outcome measure was the endurance capacity measured by the six-minute walk test (6MWT). The secondary outcome measures were the results of the St. George''s Hospital Respiratory Questionnaire (SGRQ) and the COPD assessment test (CAT).Results:Participants in the group that performed aerobic exercise using a cycle ergometer had significantly improved 6MWT (P = .005), SGRQ (P = .029), and CAT (P = .018) results. Participants in the Qigong exercise group had significant changes in 6MWT (P = .033). However, the differences in 6MWT and SGRQ were not statistically significant between the 2 groups. The changes in CAT scores before and after the intervention were significantly different between the 2 groups (P = .020). There were no reports of adverse events during the course of the trial.Conclusions:There was no difference in the primary outcome between groups. In particular, QE and cycle ergometer exercise had similar rehabilitation effects on the improvement of the cardiopulmonary endurance and quality of life of chronic obstructive pulmonary disease patients. In addition, cycle ergometer exercise may lead to a better trend of improvement in the quality of life and can improve the severity of the clinical symptoms of chronic obstructive pulmonary disease.Trial registration:ChiCTR-TRC-14004404.     

Radionuclide assessment of left ventricular function during dobutamine infusion in patients with coronary artery disease: comparison with ergometer exercise

The effects of dobutamine on left ventricular function were assessed employing radionuclide ventriculography (RNV) in 7 normal subjects (Group 1) and 21 patients with coronary artery disease (Group 2). After routine bicycle ergometer exercise RNV, dobutamine infusion was started at 5 micrograms/kg/min and the dosage was increased by 5 micrograms/kg/min every 4 minutes to a total of 15 micrograms/kg/min. In Group 1, left ventricular ejection fraction (LVEF) increased by both ergometer exercise and dobutamine infusion. In Group 2, LVEF did not increase during exercise, but increased during dobutamine infusion without evidence of significant myocardial ischemia. Only 2 patients in Group 2 had new regional wall motion abnormality. Left ventricular end-diastolic volume (LVEDV) in Group 2 increased from 191 +/- 19 to 210 +/- 18 ml during ergometer exercise, but decreased from 193 +/- 18 to 153 +/- 19 ml during dobutamine infusion. Short-term low-dose infusion of dobutamine may be used in patients without evidence of significant myocardial ischemia, but probably cannot be substituted for exercise testing in patients with mild to moderate coronary artery disease.     

17β-Estradiol Enhances Contact Hypersensitivity in a Hair Cycle-Dependent Manner and Retards Thymic Atrophy with Age

The effect of 17β-estradiol (E2) on murine contact hypersensitivity (CHS), thymic atrophy, and hair-cycle change related to growth was investigated. Female mice were ovariectomized. E2 (3.2 μg) was injected subcutaneously along with the sensitizer 4‐ethoxymethylene-2-phenyl-2-oxazolin-5-one (OXA), and a hypersensitive reaction was elicited with OXA on the ear in mice of various ages. E2 enhanced allergy only in 3- and 7-week-old mice, just prior to hair regrowth. Age-related thymus atrophy was repressed in the E2-treated mice compared with the control mice. E2 alone did not cause thymus involution, but it did inhibit thymus involution and regeneration after CHS.
