胃癌术后肠内营养应用方法及耐受性分析

目的探讨胃癌术后肠内营养（EN）耐受性影响因素及EN具体实施方法。方法选取2011年11月至2012年9月在青岛大学医学院附属医院普外科行胃癌手术的患者54例为研究对象,以序贯、渐进的方法实施EN,观察EN耐受情况,对患者EN耐受性进行单因素和多因素Logistic回归分析,记录患者EN期间的消化道症状。结果54例患者中,49例（90．74％）能耐受EN。肿瘤分期（单因素分析：X2=7．287,P=0．007;多因素分析：t=2．559,P=0．014）、手术方式（单因素分析：X2=7．825,P=0．005;多因素分析：t=2．254,P=0．043）是影响EN耐受性的因素。在耐受患者中,EN期间胃肠道症状以腹胀为主（19／49,38．8％）。结论序贯、渐进的EN方法适合胃癌术后患者,可在临床推广应用。     

A pilot study of the SARC-F scale on screening sarcopenia and physical disability in the Chinese older people

Introduction

The SARC-F scale is a newly developed tool to diagnose sarcopenia and obviate the need for measurement of muscle mass. SARC-F ≥ 4 is defined as sarcopenia. The questions of SARC-F cover physical functions targeting sarcopenia or initial presentation for sarcopenia. The aim of the study is to explore the application of SARC-F in the Chinese people.

Methods

Two hundred thirty Chinese people over 65 years old were assessed by the SARC-F scale, PSMS, Lawton IADL and the shortened version of the falls efficacy scale-international (the short FES-I). Hospitalization was investigated. Physical performance and strength were measured. The association of SARC-F with other scales or tests was analyzed.

Results

Poor physical performance and grip strength were associated with SARC-F ≥ 4 independently (P<0.005). The value for agreement of SARC-F ≥ 4 and cutoff points of tests were 0.391 to 0.635. The short FES-I were correlated to SARC-F scores (Spearman’s coefficient 0.692). Poor PSMS and Lawton IADL scores were associated with SARC-F ≥ 4(P=0.000) and SARC-F ≥ 4 was associated with hospitalization in the past 2 years (P=0.000).

Conclusion

The SARC-F scale can identify old Chinese people with impaired physical function who may suffered from sarcopenia. SARC-F judgment reflects fear of falling, indicates the hospitalization events and is associated with ability of daily life. Thus, SARC-F may be a simple and useful tool for screening individuals with impaired physical function. Further studies on SARC-F in Chinese people would be worthy.

有机固体废物处理行业臭气的产生与控制

针对目前主流的有机固体废物处理处置工艺,总结了各工艺的臭气成分和影响因素。恶臭物质NH3和H2S在污泥堆肥、污泥干化、餐厨垃圾好氧分解和生活垃圾填埋场中都有产生,但不同处理工艺的主要致臭物质不同。污泥堆肥工艺的主要致臭物质为含硫化合物,污泥干化工艺和垃圾填埋场的主要致臭物质为苯系物和萜烯类,餐厨垃圾好氧分解的主要致臭物质为含氧类化合物。提出了相应的恶臭防控措施。
