白血病是一类起源于造血(或淋巴)干细胞的恶性疾病.化疗仍是白血病治疗的主要手段.化疗药物不但杀伤白血病细胞,而且可直接破坏口腔黏膜屏障,加之在化疗期间,抗肿瘤药物及激素的应用及免疫抑制剂、大量抗菌药物的使用,致使患者抵抗力急剧下降从而引发各种口腔疾患.

新生儿湿肺又称新生儿暂时性呼吸困难,是因肺内液体积聚和清除延迟引起的自限性呼吸系统疾病,多见于足月儿或足月剖宫产儿,亦可见于早产儿.多数在出生后6 h内即出现呼吸加速(＞60次/min).轻症较多,症状仅持续12～24 h.但近年重症亦较多,主要是早产儿,症状可拖延到2～5 d,表现为哭声低弱、青紫、轻度呻吟、鼻煽、三凹征、呼吸急速(＞100次/min),发生呼吸衰竭、心力衰竭,甚至死亡.

目的观察肺部感染患者与血清超敏C反应蛋白(CRP)含量的关系。方法对312例肺部感染患者在治疗前和感染控制后检测超敏CRP水平,并与85例健康人群进行对照研究。结果肺部感染时血清超敏CRP阳性率显著增高,敏感性亦高于体温和白细胞计数。结论超敏CRP测定可作为诊断肺部感染及疗效判断的一项较敏感的指标。

OBJECTIVE To understand pathogen distribution and drug resistance of urinary system infection in Langfang,then help the clinic to use drug rationally.METHODS Totally 846 bacteria were isolated from the urine and given in vitro drug sensiticity test with Kirby-Bauer method to detect special resistant strains such as MRS,VRE,HLAR and the ESBLs-producing bacteria.RESULTS The first 5 were Escherichia coli(60.2%),cogulase negative Staphylococcus (CNS,16.7%),Klebsiella pneumoniae(3.2%),Enterococcus(2.6%),and Proteus(2.1%).ESBLs-producing bacteria were 23.5%,MRS were 83.7%,HLAR were 59.1%,VRE were not detected.E.coli was sensitive to cefepime,piperacillin/tazobactam,ceftazidime,amikacin(71.0-99.0%).CNS was sensitive to vancomycin,piperacillin/tazobactam,nitrofurantoin,and ofloxacin(70.0-100.0%).Vancomycin-resistant CNS was not detected.CONCLUSIONS E.coli is the most encountered pathogen causing urinary system infection in Langfang,Then are CNS.Antibiotics we were used such as gentamicin,ciprofloxacin,et,al already produced higher resistance,so clinic should consider the drug sensitivity agent and special resistant strain and choice antibiotics rationally,to make the resistant streains decreasing in number.

目的了解老年病人住院期间院内呼吸道感染情况。方法对我院2006年1月~2007年10月住院的老年病人进行回顾性调查,统计分析试验资料。结果1100例老年住院患者的痰标本中,分离出致病菌346例,占31.4%(346/1100)其中男性238例,女性108例,菌群组成以G-杆菌为主,真菌次之,G+球菌很少,G-杆菌对氨苄西林的耐药率高达90.1%,其耐药率较低的抗生素为丁胺卡那。结论老年病人患严重基础症病,抵抗力低下,易感菌群为G-杆菌,真菌次之。
