如何避免激光术后常见并发症

据一位经验丰富的激光外科医师说,通常所认为激光能够毫无损伤去除毛发、文身和胎记的观念是错误和有害的. C.B. Zachary医师是旧金山加利福尼亚大学皮肤外科和激光中心的临床教授和主任,他认为在医疗机构中,激光只能由经验丰富的护士和技师在皮肤科医师或其他经过相应训练的内科医师监督下实施.     

指固有动脉串联皮瓣修复右食指多处皮肤坏死1例

患者男性，28岁，因电锯伤右手1h于2006年2月10日急诊入院，术前检查：右食指自远侧指间关节处完全离断，创面不整齐，离断指体挫伤较重，入院诊断：右食指完全离断。急诊在臂丛神经麻醉下行右食指清创再植术，吻接动、静脉，修复双侧指神经。术后常规“三抗”治疗。术后血运好。术后第7d出现血管危象，给予相应处理。术后12d右食指末节指腹及中节指背皮肤部分坏死。术后第39d在臂丛神经麻醉下行右食指坏死组织清除、中指桡侧指固有动脉串联皮瓣修复术。术后皮瓣存活，术后10d痊愈出院。     

308例肛裂手术治疗三种术式的临床对比

对治疗肛裂的主要术式：肛侧位闭式切扩术，后正中切扩术，侧位内括约肌挑出切扩术进行疗效比较，认为肛门侧位内括约肌挑出切断扩肛术具有疗效好、愈合时间短、痛苦小、并发症少、操作简便等优点，为治疗肛裂的首选术式。     

放射性核素在诊疗过程中的注射方法及护理

核医学是一门利用开放型放射性核素诊断和治疗疾病的学科,在现代医学中有着重要的地位和作用。诊疗工作中第一步就是要将放射性核素及其标记化合物通过一定途径引入人体,如口腔、吸入和注射。注射是所有这些手段中最主要的一种,其过程顺利与否关系到整个检查,影响诊断及治疗的质量。现结合实际工作做一大致的归纳。1注射方法分类1.1皮内及皮下注射淋巴结及淋巴管显像需要进行皮内注射,要求针尖刺入皮内时回抽不能有血,否则显像剂进入血管后淋巴结及淋巴管显像不佳。1.2静脉注射(1)普通静脉注射:要求将所用显像剂全部注入静脉内,尽可能避免外…     

艾易舒注射液联合介入治疗中晚期肝癌36例疗效分析

目的观察艾易舒注射液联合介入治疗中晚期肝癌的疗效及不良反应。方法将72例中晚期肝癌随机分成治疗组36例和对照组36例,治疗组:艾易舒注射液0.5mg/d、静滴、d1-14,于第3天行介入治疗,术中动脉注射艾易舒注射液0.5mg。对照组单纯行介入治疗。2～3周期为一疗程,观察疗效和不良反应。结果治疗组总有效率48.5%(CR PR),中位生存期12个月,18个月生存率34.3%,24个月生存率为14.3%,生存质量提高率60%。对照组总有效率33.5%(CR PR),中位生存期8.9个月,18个月生存率12.1%,24个月生存率为0,生活质量提高率27.2%。结论艾易舒注射液联合介入治疗中晚期肝癌,可提高生活质量,延长中位生存期,提高长期生存率,值得进一步探讨。

表达谱基因芯片筛选体外循环前后心肌细胞因子的变化

Objestive Systemic inflarmmation may be triggered by injury, hypothermia, ischemia-reperfusion and the contact of the blood with foreign body during cardiopulmonary bypass (CPB). To determine the application values of gene chip technique in the clinical practice and the study of cardiovascular stagery, as well as to provide clues to the study of inflammatory responess during CPB, microarry for gene expression profiles was used to identify the differences in the gene expression of myocardium between pre-and post- CPB. Methods Six adult patients who underwent CPB from March to May in 2003 were involved. Samples of right atrium were col- lected before and at immediate end of CPB. BD AtlasTM cDNA Expression Arrays was used to identify the differences in the gene ex- pression of cytokines. The results were compared with that of semi-quantative RT-PCR. Resellts The mean age of 6 patients (5 males and 1 female) was (32.67± 11.72) years. The baseline heart function was gradeⅡin 3 cases and grade Ⅲ in 3 other cases. The baseline left ventricular ejection fraction(LVEF)was (58.17±7.91)%. The mere duration was (91.67±43.88) minutes for CPB and was (58.67±43.46) minutes for aorta blocking. The minimum nasopharynx/rectal temperture was (29.37±1.90)℃/ (32.15±1.52)℃. Gene expression profiles of cytokines in the myocardium pre- and post-CPB were analysed successfully. The ex- pression of IL-6, IFN-γ,Wnt5a, TNFRSF1B, a member of tumor necrosis factor receptor superfamily, PIGF and MFNG in the myo- cardium were unpregulated after CPB. Conclusion Microarray technique is applicable in the study of cytokines changes dying CPB. cDNA microarray identified pleliminarily the differences in the gene expression between pre- and post-CPB. These genes may be in- valved in inflammation and other psthophysiological responses incuced by CPB. The myocardiym is probably one of the major sources of cytokines during CPB. Further study may be helpful in understanding the llngthe development of inflammation during CPB, and eventually, reducing the post-operative complications.
