军团菌肺炎的临床特点探讨

作者对１０例军团菌肺炎和１０例非军团菌肺炎患者临床资料进行分析。本组军团菌肺炎特点为：病情重、进展快、消化道症状及肌肉关节痛、低钠血症、低氧血症、代酸或呼碱发生率较高，Ｘ线胸片多见双侧或多叶肺浸润伴胸膜反应，病死率高。     

Flow-induced Expression and Phosphorylation of VASPin Endothelial Cells

1 Introduction It is well known that mechanical forces have important influence on endothelial cells, in particular, on cytoskeleton reorganization. VASP (vasodilator stimulated phosphoprotein) is a 46 KD actin associated protein. It is a member of Ena/VASP protein family and composed of EVH1, proline-rich and EVH2 domains. It is considered as an important component of the sub-cellular regions where remodelling of the actin cytoskeleton takes place, such as the front of spreading lamell…     

原发性肺淋巴瘤2例并文献复习

目的提高原发性肺淋巴瘤的诊治水平。方法对二例原发性肺淋巴瘤进行分析,结合文献对其临床特点、影像改变、诊断及治疗方法进行分析。结果原发于肺的淋巴瘤无特异性临床表现和影像改变,易误诊。确诊依靠组织病理检查。结论及时进行有创检查有利于早期诊断。     

吸入沙美特罗氟替卡松对COPD缓解期的影响

目的研究吸入沙美特罗氟替卡松干粉对缓解期慢性阻塞性肺疾病(COPD)患者肺功能的影响。方法将缓解期COPD患者随机分为两组,实验组在对照组基础加用沙美特罗氟替卡松干粉吸入,于入组时、用药后4周及l2周症状评分和肺功能检查。结果两组症状评分和肺功能在4周和l2周时均有改善,实验组改善程度远高于对照组。结论吸入沙美特罗氟替卡松干粉能改善中重度COPD缓解期患者的症状评分和肺功能。     

响应面法优化白刺花总黄酮提取工艺研究

目的:优选白刺花中总黄酮的最佳提取工艺。方法:采用响应面分析法优化,以总黄酮提取率为评价指标,在考察单因素试验的基础上,选取乙醇浓度、加液量、提取温度和提取时间为自变量,利用Design-Expert软件分析优化出白刺花中总黄酮的最佳提取工艺条件。结果:优化所得白刺花中总黄酮的最佳提取工艺条件为:乙醇浓度为72%,加液量为21倍,提取温度为71℃,提取时间为133 min。结论:响应面优化所得到的最佳提取工艺准确、稳定,是提取白刺花中总黄酮的可行方法。     

腺苷脱氨酶、溶菌酶和乳酸脱氢酶联合检测对恶性胸(腹)水诊断价值

分析43例恶性胸(腹)水的腺苷脱氨酶(ADA),溶菌酶(LZM)以及乳酸脱氢酶(LDH),其中93％ADA活力低于30u/L,83.7％LZM浓度低于30mg/L,而95.3％LDH高于80IU。发现ADA、LZM的低值及LDH增高是恶性重要特征,而ADA与LDH呈负相关,其特异性优于LZM与LDH。     

Chronic neuroprotective effects of low concentration lithium on SH-SY5Y cells:possible involvement of stress proteins and gene expression

To investigate the molecular mechanism underlying the neuroprotective effect of lithium on cells, in this study, we exposed SH-SY5Y cells to 0.5 mmol/L lithium carbonate(Li2CO2) for 25–50 weeks and then detected the expression levels of some neurobiology related genes and post-translational modifications of stress proteins in SH-SY5Y cells. cDNA arrays showed that pyruvate kinase 2(PKM2) and calmodulin 3(CaM 3) expression levels were significantly down-regulated, phosphatase protein PP2A expression was lightly down-regulated, and casein kinase II(CK2), threonine/tyrosine phosphatase 7(PYST2), and dopamine beta-hydroxylase(DBH) expression levels were significantly up-regulated. Besides, western blot analysis of stress proteins(HSP27, HSP70, GRP78 and GRP94) showed an over-expression of two proteins: a 105 kDa protein which is a hyper-phosphorylated isoform of GRP94, and a 108 kDa protein which is a phosphorylated tetramer of HSP27. These results suggest that the neuroprotective effects of lithium are likely related to gene expressions and post-translational modifications of proteins cited above.     

百令胶囊对频繁发作 ＣＯＰＤ 病人免疫功能和肺功能的影响

目的：观察百令胶囊对频繁发作慢性阻塞性肺疾病（ＣＯＰＤ）病人免疫功能和肺功能的影响。方法： 选取 １００ 例年发作次数在 ２ 次以上，每次发作均来本院呼吸内科住院诊治的慢性阻塞性肺疾病急性加重期病人 （ＡＥＣＯＰＤ）。５２ 例对照组病人在常规治疗的基础上增加无创正压通气（ＮＩＰＰＶ），４８ 例观察组病人在对照组之 上增加百令胶囊治疗。观察两组病人治疗前后免疫功能和肺功能情况。结果：观察组临床治疗有效率为８３．３３％ 显著高于对照组的６５．３８％，有统计学意义（χ２ ＝ ４．１８，Ｐ＜０．０５）；观察组治疗后 ＦＥＶ１ 、ＦＥＶ１ 预测值、ＦＥＶ１ ／ ＦＶＣ 均 高于对照组，差异有统计学意义（Ｐ＜０．０５）；观察组治疗后 Ｔ 淋巴细胞亚群 ＣＤ４＋、ＣＤ４＋ ／ ＣＤ８＋高于对照组，ＣＤ８ ＋低于对照组，均有统计学差异（Ｐ＜０．０５）。结论：采用百令胶囊辅助治疗，可改善病人免疫功能，提高肺功能，有 望降低 ＡＥＣＯＰＤ 发作次数。
