保留足趾的自体复合第2足趾关节移植治疗手指关节炎

目的 探讨保留足趾的自体复合第2足趾关节移植治疗手指关节炎的临床疗效.方法 2016年2月至2018年6月,共收治创伤性手指关节炎9例,其中男7例,女2例;年龄19~53岁,平均31.7岁;示指3例,中指6例;掌指关节(MP)关节炎4例,近侧指骨间关节(PIP)关节炎5例;均为创伤后继发的手指关节炎.采用游离带血供的自体复合第2足趾跖趾或趾骨间关节移植进行治疗,同时将受区废弃关节(7例)或切取自体髂骨移植(2例)修复供区骨缺损保留足趾长度,供区创面均直接关闭.术后观察手指和足趾骨折愈合情况、外形、移植关节活动度(ROM)、术后供区愈合情况和行走功能及相关并发症.结果 本组术后9例移植关节全部成活,1例足部供区行髂骨植骨微型钢板固定,术后1周伤口不愈合,考虑为内固定物排异反应,予拆除钢板改克氏针交叉固定,2周后创口顺利愈合.术后随访6~30个月,平均16.3个月.手指骨折平均愈合时间7~10周,平均8.3周,手指外观及功能良好.移植后的MP活动度为50°~75°,平均65.3°,PIP活动度为10°~85°,平均60.6°.根据中华医学会手外科学分会上肢部分功能评定试用标准评价手指功能:优5例,良3例,可1例,优良率为88.9%.足趾骨折平均愈合时间9~12周,平均10.2周,所有患者足趾外形良好,行走功能正常.2例取髂骨患者供区仅残留一条线形瘢痕,无疼痛、麻木等不适.结论 游离带血供的自体复合第2足趾关节移植治疗手指关节炎,同时应用受区废弃关节或切取自体髂骨移植修复供区骨缺损保留足趾,不仅能恢复手指关节的正常结构,使关节具有良好的功能,而且能保留足趾外形与功能,减少供区损伤,具有良好的治疗效果.     

Sequential Therapy Based on Evolvement of Patterns: A New Model for Treatment of Alzheimer’s Disease

In order to solve the problem of long-term (>9 months) efficacy in the treatment of Alzheimer''s disease (AD) by conventional therapy (CT), a staged and multiply-targeted sequential therapy based on the evolvement of patterns (STEP) was developed. Its main innovations include: (1) the time order of evolution of patterns defined by Chinese medicine (CM) in AD was found, that is, "the orderly pattern evolution starting from Shen (Kidney) deficiency, progressing to phlegm, stasis and fire, and worsening to severe toxin as well as functional collapse"; (2) the cascade hypothesis of Shen deficiency in AD and its sequential therapy based on Shen-reinforcing was proposed, that is, "reinforcing Shen in the early stage and throughout the whole process, resolving phlegm, activating blood and purging fire in the middle stage, detoxifying and replenishing vitality to stop the collapse in the advanced stage", and through meta-analysis, clinical drug use was optimized, thus the leap from "inferential selection" to "evidence-based selection" was realized; (3) the STEP regimen combined with CT maintained cognitive and behavioral stability in AD patients for at least 12 months, with cognitive enhancement and behavioral synergy after 9 months, and cognitive benefit was superior to CT at 9, 12, 15, 18, 21, and 24 months, respectively. The 2-year cognitive improvement rate was increased by 25.64% (P=0.020) and the cognitive deterioration rate was decreased by 48.71% (P=0.000). Among them, the cognitive and functional benefits of Shen-reinforcing therapy for very early AD (350 cases) for 1 year were better than the placebo (P<0.001), and the dementia conversion rate was reduced by 8.85% (P=0.002). The behavioral symptomatic relief of patients with vascular dementia received fire-purging therapy (540 cases) was superior to those received CT (P=0.016). These data suggested that the STEP regimen has synergistic effects on CTs at least in terms of cognitive benefit, and the earlier the use, the greater the benefit will have. Therefore, the STEP regimen should be considered as one of the clinical options, particularly for the dearth of effective pharmaceutical or immunological interventions that are currently available for AD.

医用粘胶相关性皮肤损伤的文献计量学分析

目的: 应用文献计量学方法,分析国内外医用粘胶相关性皮肤损伤（Medical adhesive-related skin injuries,MARSI）文献的研究主题和热点。方法: 检索Cochrane Library、PubMed、EMbase、Web of science、sinoMed、CNKI、Wanfang、VIP等数据库MARSI相关文献,检索时限为建库至2019年5月。采用SPSS 22.0 软件进行文献计量分析,利用gCLUTO统计对国内外高频主题词进行聚类分析。结果: 共纳入论文103篇,其中外文文献占总文献量的27.18%,中文文献占总文献量的72.82%。聚类分析将国内外高频主题词聚为4大类,依次为皮肤损伤及损伤类型、相关危险因素、风险评估及风险管理、护理干预措施。结论: MARSI仍是国内外研究的热点,其发病机制研究仍处于探索阶段,目前尚缺乏有效的预防策略,研究领域较局限。在今后的研究中,应加强MARSI预防的研究、注重多学科合作。     

员工援助计划服务对心内科护士职业认同感、职业价值观、职业压力的影响

目的 探讨员工援助计划服务对心内科护士职业认同感、职业价值观、职业压力的影响。 方法 选择2018年1-3月我院心内科护理人员58名,为其实施员工援助计划服务,评价实施前后心内科护士的职业认同感、职业价值观、职业压力感知、职业压力反应。 结果 实施后,心内科护士工作压力源各维度评分、压力感知与压力反应各维度得分均较实施前下降(P＜0.05);职业价值观各维度及职业认同感各维度评分均较实施前显著提高(P＜0.001)。 结论 员工援助计划可提高心内科护士职业认同感、职业价值观,缓解其职业压力感知以及职业压力反应。
