心电图正常的急性肾功能衰竭患者心肌酶的意义

目的:探讨血清心肌酶在心电图(ECG)正常的急性肾功能衰竭(ARF)患者中的意义。方法:选择ECG正常的ARF患者及正常健康成人各30例,测定其血清心肌酶．比较ARF患者及正常健康人血清心肌酶。结果:ARF组血清CK、LDH活性均高于对照组(P＜0．01)。结论:ARF患者当ECG正常时血清心肌酶已经升高,血清心肌酶的测定能早期发现ARF时的心肌损害。     

健康教育路径对HBsAg阳性产妇母乳喂养依从性的影响

目的探讨健康教育路径对HBsAg阳性产妇母乳喂养依从性的影响。方法便利抽样法选择2009年1月至2011年1月住院分娩的238例HBsAg阳性产妇为观察组,采用健康教育路径方式宣教;选择2006年12月至2008年12月住院分娩的263例HBsAg阳性产妇为对照组,采用传统健康教育方式进行宣教。比较两组产妇母乳喂养依从性及产妇母乳喂养知识知晓情况。结果观察组产妇对于母乳喂养的相关知识知晓情况较好,得分80分以上的占70.59%,与对照组相比,差异有统计学意义(P<0.001)。观察组中,哺乳≥6个月的产妇占69.75%,哺乳<6个月者占19.75%,未采用母乳喂养者仅占10.50%,与对照组相比,差异有统计学意义(P<0.01)。结论 HBsAg阳性产妇进行母乳喂养并不增加婴儿乙型病毒性肝炎病毒(hepatitis B virus,HBV)的感染率,健康教育路径能有效提高产妇母乳喂养的依从性及喂养知识知晓情况。     

脑出血不同治疗方法下血肿吸收率的动态演变及对比

目的：使用CT血肿体积测量软件探讨脑出血在不同治疗方法下血肿吸收率的动态演变及对比,为临床治疗方案的制订提供依据。方法：CT血肿体积测量软件对脑出血保守治疗及锥颅引流术前、后不同时间点的血肿体积分别进行测量、计算血肿吸收率并对比分析。结果：保守治疗组在脑出血后第1、3、7天复查,出血量大于30ml组血肿平均吸收比率分别为8.12%,15.04%,26.17%;首次出血量分别为<10ml、10~20ml、20~30ml者血肿吸收比率依次减小。引流组于引流术后第1、3、7天复查CT血肿吸收率逐渐增大：30.19%、34.11%、58.38%。引流组与保守治疗组第3、7天复查血肿体积减小比率有显著差异（P<0.0001）。结论：脑出血保守治疗后血肿体积变化特点：初始出血量小吸收快,出血量大则吸收慢;脑出血量大于30ml的病人,在能耐受手术的情况下行锥颅引流术残余血吸收速度加快。     

A simple and economical method for the manual construction of frozen tissue arrays

Tsao S‐C, Wu C‐C, Wen C‐H, Huang Y‐C, Chai C‐Y. A simple and economical method for the manual construction of frozen tissue arrays. APMIS 2010; 118: 739–43. Tissue microarray has been developed to enable multiple cores of tissue in one or more new paraffin blocks. Currently, almost all tissue microarrays are made by coring cylindrical tissues from formalin‐fixed and paraffin‐embedded tissues. The disadvantages of formalin‐fixed and paraffin‐embedded tissues include the poor preservation of antigenicity of certain proteins and mRNA degradation induced by the fixation and embedding process. However, frozen tissue array construction presents technical difficulties, and tissue array devices are expensive, particularly for small‐ and medium‐sized laboratories. We describe a simple manual method for producing well‐aligned tissue arrays by a capsule freeze method that allows us to successfully perform hematoxylin–eosin and immunohistochemical stain. All 120 tissue samples were collected and constructed into blocks by this capsule freeze method. The capsules were not affected during the sectioning process, and the capsule material always disappeared during the aqueous steps of the stain processing. The frozen tissue arrays were smoothly sectioned without the use of a tape transfer system and immunohistochemical study was performed with satisfactory results. This alternative method can be applied in any laboratory, and is both simple and economical.     

恶性淋巴瘤自体造血干细胞移植后复发的研究进展

自体造血干细胞移植 (ASCT)是治疗复发性、难治性和侵袭性恶性淋巴瘤的有效方法 ,但因存在体内肿瘤细胞负荷过多和移植物被肿瘤细胞污染 ,使移植后的复发率增高。为了提高ASCT的疗效 ,可采取 :①移植前美罗华体内净化 ,除去外周血B细胞 ,清除移植物的肿瘤细胞污染 ;②移植后用美罗华和非交叉耐药药物交替联合化疗 ,以杀伤体内肿瘤细胞 ;③移植前或后累及野放射治疗 (IFRT)辅助 ,降低原发灶的复发率     

海洛因依赖者心理健康在戒毒次数上的变化规律及其影响因素分析

目的探究强制隔离戒毒模式下不同性别海济吲依赖并的心理健康水平存成毒次数上的变化规律,为不同性别戒毒并的心理门磺提供依据。方法用自编一般情况凋查表、90项症状清单（SCL-90）、艾森克人格问卷（EPQ）、特质应对方式问卷（TCSQ）和礼会支持评定量表（SSRS）对386例海洛因依赖者进行测验。结果（1）海洛冈依赖者SCL-90各冈子分湿著高于常模（P〈0．001）。（2）男性首次戒毒者SCL-90各因子得分较低,然后随着戒毒次数呈现高低交替的波动性变化,而女性戒毒者的心理健康状况相埘平稳。（3）人格是影响男性戒毒者心理健康的主要因素,而对于女性戒毒者,人格、应埘方式和年龄三种渊素影响差别不明显。结论戒毒者心理健康水平较差,对男性戒毒者,要加强心理健康及其影响因素的监测,尤其要关注其人格改变     

奥曲肽和垂体后叶素治疗肝硬化上消化道出血的疗效对比

目的对比奥曲肽和垂体后叶素治疗肝硬化上消化道出血的疗效。方法选取我院2017年8月至2019年2月收治的肝硬化上消化道出血患者100例,随机分为对照组和观察组各50例。对照组采用垂体后叶素治疗,观察组采用奥曲肽治疗,比较两组的止血时间、住院时间、不良反应发生率及治疗前后的血清胰高血糖素水平。结果观察组的止血时间、住院时间均明显短于对照组(P<0.05)。治疗后,观察组的血清胰高血糖素水平明显低于对照组(P<0.05)。观察组的不良反应发生率为14.00%,明显低于对照组的50.00%(P<0.05)。结论与垂体后叶素比较,采用奥曲肽治疗肝硬化上消化道出血患者可更加快速止血,降低机体胰高血糖素水平及不良反应发生率,值得临床推广。     

Local and transient inhibition of p21 expression ameliorates age‐related delayed wound healing

Nonhealing chronic wounds in the constantly growing elderly population represent a major public health problem with high socioeconomic burden. Yet, the underlying mechanism of age‐related impairment of wound healing remains elusive. Here, we show that the number of dermal cells expressing cyclin‐dependent kinase inhibitor p21 was elevated upon skin injury, particularly in aged population, in both man and mouse. The nuclear expression of p21 in activated wound fibroblasts delayed the onset of the proliferation phase of wound healing in a p53‐independent manner. Further, the local and transient inhibition of p21 expression by in vivo delivered p21‐targeting siRNA ameliorated the delayed wound healing in aged mice. Our results suggest that the increased number of p21⁺ wound fibroblasts enforces the age‐related compromised healing, and targeting p21 creates potential clinical avenues to promote wound healing in aged population.
