富氧水防治急性高原病的效果观察

目的:观察饮用富氧水防治急性高原病的效果。方法:36名受试者自海拔1400m驻地乘汽车2天到达海拔3700m当日随机分两组,实验组(18人)口服5%葡萄糖注射液制成的富氧水,对照组(18人)口服5%葡萄糖注射液,均每次500mL,一日2次,直至进入海拔5200m某哨卡第6天,共服液8天。以军用卫生标准GJB1098-91"急性高原反应的诊断和处理原则"随访记录受试者进入哨卡第2天、4天、6天急性高原反应症状,然后分度与评分。同时检测血氧饱和度(SaO2)和脉率。结果:进驻哨卡第2天和第4天实验组较对照组急性高原反应分值减少,而SaO2增高(P<0.05或P<0.01),进驻哨卡第2天实验组较对照组脉率降低(P<0.05)。结论:饮用富氧水有防治急性高原病的效果。     

急性右下腹痛的B超诊断

急性右下腹痛是医院急诊病人的常见症状。对２０６例急性右下腹痛病人进行Ｂ超检查，包括急性盆腔炎，急性阑尾炎，输尿管结石，输卵管妊娠破裂，卵泡破裂，卵巢囊肿蒂扭转，阑尾粘液腺癌，腹腔淋巴结核合并感染，因阑尾炎的Ｂ超诊断报道较少，所以着重详细描述了各类型阑尾炎的声像图特征，报道的相关病例全部经手术及病理证实，认为Ｂ超检查对急性右下腹痛的诊断和鉴别诊断有一定的临床意义。     

急性心肌梗塞墓碑形S—T段抬高的预后

对156例急性心肌梗塞进行临床分析。结果显示墓碑形S—T段抬高组CK值、心梗后心绞痛(PIA)、严重心律失常、心衰发生率，以及一周内死亡率较通常式抬高组显著增高。结论：墓碑形S—T段抬高可作为判断急性心肌梗塞预后不良的一项参考指标。     

检测胞浆抗原用于急性白血病免疫分型

目的:探讨胞浆抗原在急性白血病免疫分型中的临床意义。方法:用流式细胞仪检测42例初治急性白血病患者胞浆抗原CyCD_3,CyCD_(22),CyCD_(79a)和MPO。结果:T—ALL阳性胞浆抗原主要表达在CyCD_3,阳性率占88.9％。B—ALL阳性胞浆抗原主要表达在CyCD_(79a),AML主要表达CyMPO。结论:CyCD_3和CyCD_(79a),及MPO可分别作为T—ALL,B—ALL和AML系列特异性标志,对正确诊断白血病提供非常有价值的依据。     

全反式维甲酸对骨髓纤维细胞的影响

通过纤维细胞集落(CFU-F)的培养,观察了急性早幼粒细胞性白血病(APL)的CFU-F,结果APL 患者较正常骨髓明显低下(4.3±1.63/2×10~5细胞)(n=9);完全缓解后则上升达正常水平(12.4±2.55/2×10~5)。体外试验,维甲酸(RA)加入CFU-F 培养系后,CFU-F 下降为3.11±1.24/2×10~5细胞,明显低于对照组8.5±1.57/2×10~5(P<0.05)。提示RA 对骨髓纤维细胞有抑制作用,此结果可能为RA 治疗骨髓纤维化提供初步依据。     

Prognosis of acute renal failure in children: a multivariate analysis

Various factors were analyzed in 80 consecutive children under 16 years who had acute renal failure (ARF), for various prognostic factors. Overall mortality was 42.5%, with significantly higher levels seen in hemolytic uremic syndrome (68%, P <0.05) and associated with cardiac surgery (90.9%, P <0.01). Anuria (67.6% vs. 43.5%, P <0.05), need for dialysis (85.3% vs. 56.5%, P <0.05), neurological complications (50% vs. 6.3%, P <0.01), and respiratory complications (35.2% vs. 2.1%, P <0.01) were significantly higher in nonsurvivors than survivors. Multiple regression analysis showed the presence of neurological and respiratory complications to be poor prognostic factors.

In vivo carbon monoxide exposure and hypoxic hypoxia stimulate immediate early gene expression

 This study aimed to examine the influence of acute tissue hypoxygenation on the expression of immediate early genes in different rat tissues. To this end male Sprague-Dawley rats were exposed to 0.1% carbon monoxide for 0.5, 1 and 6 h or to 9% oxygen for 6 h and mRNA levels for c-jun, c-fos, c-myc and EGR-1 were assayed by RNase protection in hearts, kidneys, livers and lungs. We found that hypoxia increased c-jun mRNA levels between twofold (lung) and eightfold (liver) in all organs examined; c-fos mRNA increased between threefold (lung) and 20-fold (heart); c-myc mRNA increased between twofold (lung) and sixfold (heart); and EGR-1 mRNA increased between twofold (lung) and sixfold (heart). Our findings suggest that acute tissue hypoxygenation is a general stimulus of the expression of immediate early genes in vivo. With regard to the sensitivity to hypoxia, organ differences appear to exist in that the lung is rather insensitive, whilst the heart is rather sensitive.

急性心肌梗塞溶栓治疗后D-二聚体动态变化的意义

在22例符合溶栓条件的急性心肌梗塞患者，应用尿激酶溶栓治疗前后，用乳胶颗粒凝集法检测了血清D-二聚体的动态变化和对照组比较，D-二聚体含量在梗塞相关动脉（IRA）再通者明显升高（P＜0．01），而IRA未再通者仅稍有升高（P＞0．05）。结果表明，D-二聚体水平和IRA再通与否之间有良好的相关性，且方法简便，易于推广。     

Folic acid in the treatment of acute watery diarrhoea in children: a double-blind, randomized, controlled trial

One-hundred and six male children aged 6-23 months with a history of acute watery diarrhoea of less than 72 h duration were randomized to receive either folic acid in a dose of 5 mg at 8-h intervals or placebo for 5 d. There were 54 children in the folic acid group and 52 in the placebo group. The admission characteristics were comparable between the two groups. No significant differences were observed in the intake of oral rehydration solution or stool output between the groups. The mean ± SD of total stool output (g kg⁻¹) was 532 ± 476 vs 479 ± 354 and the duration (h) of diarrhoea was 108 ± 68 vs 103 ± 53 in the folic acid vs placebo group, respectively. The findings, therefore, should have a positive influence on preventing the inappropriate use of folic acid in acute diarrhoea.
