胸腺切除治疗重症肌无力的护理

重症肌无力（myasthenia gravis Mg）是以乙酰胆碱受体为靶子的自身免疫性疾病。胸腺异常是其特征性改变。胸腺扩大切除术是治疗MG的首选方法，其疗效可达81．8％-91．5％。我院胸外科自2004年7月至2008年1月对33例重症肌无力患者进行以胸腺切除为主的综合治疗，术后病情均有不同程度的缓解，效果满意。现将围手术期的护理体会介绍如下。

超声引导下经皮肺穿刺活检术诊断矽肺周围型病变的应用价值初探北大核心CSCD

目的探讨超声引导下经皮肺穿刺活检术诊断矽肺周围型病变的应用价值。方法对36只健康西兰兔采用非暴露法气管注入石英粉尘制备兔矽肺模型,观察染尘2个月后肺部影像学改变。对照CT结果,对肺内周围型病变行经皮超声引导下穿刺活检术。计算取材成功率、穿刺活检与解剖病理结果的诊断符合率及并发症发生率,并以成功取材、穿刺活检与解剖病理结果相符且无并发症为严格意义上的穿刺成功。比较穿刺成功组与失败组体重、心率、呼吸、体温、病变大小、与胸壁距离及尘肺期别等指标的差异。经耳缘静脉注入10000U肝素抗凝处理后,用10％氯化钾5ml处死矽肺兔,留取肺组织标本行HE染色,观察矽肺兔肺部病理改变。结果36只矽肺兔模型中,30只肺内出现周围型病变。对30只矽肺合并周围型病变模型兔进行穿刺活检,总的穿刺成功率70％（21／30）。其中,取材成功率93％（28／30）,诊断符合率86％（24／28）,并发症发生率10％（3／30）。与穿刺失败组比较,穿刺成功组病变较大,距离胸壁较近,呼吸频率低,差异均有统计学意义（P〈0．05）。两组矽肺兔体重、心率、体温、尘肺期别差异均无统计学意义（P〉0．05）。穿刺活检及解剖病理显示周围型病变内见典型的矽结节,并可见肺小动脉肌化,内膜增厚,管腔闭塞等血管重构表现。结论超声引导下经皮对矽肺周围型病变穿刺活检安全可行,可作为监测矽肺周围型病变进展过程的重要技术手段,为矽肺病的临床诊断提供参考价值;通过肺穿刺活检观察矽肺结节内细小血管改变,有助于临床进行针对性的干预治疗。     

利用吸氧面罩自制冰敷眼罩在重睑手术中的护理效果观察

目的利用吸氧面罩自制冰敷用眼罩,并比较其在重睑术后与其他冰敷方法的不同,观察其护理效果。方法将本院2016年1月~2017年1月46例行切开法重睑手术的患者分成观察组与对照组各23例。观察组于术后24 h内使用吸氧面罩制备的冰敷眼罩,对照组使用普通冰袋进行眼部冰敷。分别于术后第3、6天对两组伤口及其周围组织的创伤反应、伤口恢复情况、患者依从性等进行对比。结果观察组周围组织创伤反应较对照组明显降低(P0.05),伤口愈合无明显差异,患者依从性明显高于对照组。结论重睑术后利用吸氧面罩自制的冰敷眼罩进行眼部冰敷,患者依从性较高,舒适度提高,同时可减轻伤口局部充血或出血,降低周围组织的创伤反应,减轻水肿,促进伤口早期愈合。

封闭负压引流技术预防骨科创面感染的观察与护理

临床创伤常伴有程度不同的软组织损伤,如不及时处理将形成难以闭合的创面,较易发生创面的局部感染,皮肤愈合不良甚至是皮肤溃疡与坏死[1]。我科通过193例封闭负压引流技术(VSD)预防骨科创面感染的观察与护理,取得良好效果,报告如下。资料与方法 选择2013年以来我科收治的开放性骨折、软组织损伤患者193例为观察护理对象.均伴有不同程度的感染。其中男137例,女56例;年龄(16~72)岁,平均年龄(41.7±6.5)

贵州省地方性氟中毒地区人群GSTP1基因Ile105Val位点多态性分析

Objective To investigate plasma glutathione S-transferase(GSTs) activity and GSTP1 gene Ile105Val polymorphism in Bijie City, Guizhou Province, a coal-burning fluorosis endemic area. Methods One hundred and sixty villagers from Yachi Twon using non-improved cooking stoves were selected as the non-intervened group in Bijie City, Guizhou Province where coal-burning fluorosis was prevailing; 153 villagers as the intervented group were chosen from Changchun Twon, where cooking stoves were improved; 151 villagers were served as the control group from Baiyunshan Twon, Changshun County without endemic fluorosis. The activity of GSTs was tested by colorimetric analysis with spectrophotometer. The genotype of the GSTP1 gene Ile105Val polymorphism, presenting as either homozygous wild-type (AA), or heterozygous mutation type (AG), or homozygous mutation type (GG), was detected through the PCR-RFLP procedure. Results The activity of GSTs in plasma of non-intervened group [(12.44±4.97) kU/L]was significantly lower than that of intervened group (P < 0.05), and that of intervened group[(20.78±6.20)kU/L]was significantly lower than that of control group[(24.30±6.27)kU/L, P< 0.05]. The difference of the enzyme activity of three groups were statistically significant (F = 51.71, P < 0.05), but this enzyme activity did not vary significantly in each sex of each grnup(P > 0.05). Compared intervened group [AA:67.3%(103/153), AG:29.4%(45/153),GG:3.3%(5/153)]and non-intervened group[AA:66.9%(107/160), AG:30%(48/160), GG:3.1%(5/160)]with control group[AA:74.8%(113/151), AG:25.2%(38/151), GG:0 (0/151)], the Ile105Val polymorphism site of GSTP1 gene had significant difference(χ2= 6.04,6.07, both P< 0.05), but not significant between intervened and non-intervened groups(χ2 = 0.02, P>0.05). Conclusions Fluorosis can decrease the activity of GSTs and introduce the GSTP1 gene Ile105Val polymorphism, intervention with the fluorine intake will improve the effect of fluoride on the body.
