ABL-510型血气分析仪废液瓶的改进

丹麦ABL—510型血气分析仪是一种带微处理器自动化程度很高的检验设备,在我国用户较多,其废液瓶是一种与仪器配套的一次性专用塑料瓶。每台仪器购入时仅带5只废液瓶。用完后就得重新订购,既不经济,又延误仪器的使用。针对这一情况,笔者对废液瓶进行了以下改进。

罗格列酮与全反式维甲酸对人胃癌SGC7901细胞株生长和凋亡的影响

Objective To investigate the influence of PPARγ excitomotor RSG and ATRA on gastric cancer SGC7901 cell line proliferation in vitro and its potential mechanism study.Methods Human gastric cancer SGC7901 cell line was cultured in vitro.Experiment samples were divided to blank group,10μmol/L ATRA group, 12.5μmol/L RSG group, 25μmol/L RSG group, 10μmol/L ATRA + 25μmol/L RSG group.Proliferation inhibitory effect was determined by MTI assay.Flow cytometry was used to detect cell cycle, H.E stain was used to observed micrography alteration.Expression of PPARγ protein in gastric cancer cells were measured by immunohistochemistry.PPARγ mRNA in gastric cancer cells were measured by RT-PCR.Results ATAR at concentration 10μmol/L, RSG at 12.5 μmol/L and RSG at 25 μmol/L could inhibit the proliferation of SGC7901 cells in a dose-and time-dependent, and when both agents were combined for 72h, growth inhibition ratio was (29.73 ± 0.69) %.Flow cytometry analysis revealed a cell cycle arrest at G1 and S phase, and when both agents combined, S% was (12.87 ± 0.35 )%, cell micrography tended to be normal when both agents combined.Up-regulation of PPARγ protein and PPARγ mRNA expressions were also observed, those effects were enhanced when both agents combined, and grey scale ratio was 0.646.Conclusion The ATRA and RSG could significantly induced growth inhibition of human gastric cancer SGC7901 cell, which may be associated with cell cycle arrest and inducing differentiation, activation of PPARγ protein and PPARγ mRNA expression.Synergistic effect could be caused by the combined use of the two agents.

香菇多糖联合顺铂胸腔内灌注治疗恶性胸腔积液

目的 观察香菇多糖联合顺铂胸腔内灌注治疗恶性胸腔积液的临床疗效.方法 80例经病理学或细胞学证实的恶性胸腔积液患者随机分为治疗组和对照组,每组40例.均应用中心静脉导管胸腔穿刺置管引流后,治疗组胸腔内注入顺铂和香菇多糖,对照组胸膜腔注入顺铂,每周1次,连续2～3次,4周后评价疗效、生活质量改善和毒副反应.结果 治疗组总有效率和生活质量改善率均优于对照组(P＜0.05),两组毒副反应无差异.结论 香菇多糖联合顺铂胸腔内灌注治疗恶性胸腔积液临床效果好,毒副反应小,值得临床推广.     

医用集中供气管道系统音响灯光报警器

医用集中供气管道系统以其供气连续、及时,操作简便,整洁环境,无污染,维修方便,经济实用,减轻医护人员劳动强度等优点而在各级医院广泛使用.作为医院治疗、抢救设备,对该供气系统技术指标有严格的要求.例如氧气输出压力规定控制在1.3～0.5MPa范围内,以满足氧气吸入器和病员呼吸需要.如果超出此范围,就会导致氧吸入器不能正常工作,病员不能正常吸氧的后果.因此,设计一套报警装置用来监视供气系统的工作状况是非常必要的.笔者最近设计了一种音响、灯光报警装置,当氧压低于下限0.3MPa(或高于上限值0.5MPa)时,4 XD(或3 XD)灯亮并闪烁报警,音响系统同时也发出"嘟、嘟"报警音     

血清五种肿瘤标志物联合检测鼻咽癌的研究

目的：研究一种鼻咽癌早期发现诊断的可靠方法。方法：对76例鼻咽癌患者和52例鼻咽颈部良性病变及102例正常人进行血清EBVCA－IgA和碱性蛋白、酸溶性蛋白、唾液酸、血管内皮生长因子定性和定量测定。结果：鼻咽癌患者比鼻咽颈部良性病变、正常人的5种血清肿瘤标志物的定性和定量检测差异有显著性，每一标志物对鼻咽癌检测的敏感性和特异性都不相同。结论：5种血清肿瘤标志物的定性和定量检测可作为鼻咽癌的早期发现诊断的简便可靠的检测指标，联合检测可提高对鼻咽癌检测的敏感性和特异性。
