血性恶性腹腔积液是晚期癌肿侵犯腹膜的并发症之一,由于积液中有大量红细胞,生长快,治疗困难,一直是肿瘤治疗上探讨的一大难题。为治疗癌肿侵犯腹膜导致的腹腔内出血,笔者用立止血腹腔注射液局部治疗取得良好效果。国内尚未见报道,现总结如下:1资料与方法1.1研究对象病例为我院  相似文献

In order to investigate the feasibility of serum creatine kinase (CK) and blood urea ni-trogen (BUN) in monitoring pre-competition training of badminton athletes, the pre-competition training load of 20 badminton athletes was studied, and serum CK and BUN were determined before, immediate and next morning after training. The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L (P<0.05). After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L (P<0.05). BUN contents were increased by 0.83 mmol/L on average with the difference being not significant (P>0.05). After intermittent training, there was significant difference in the average increased levels of serum CK in athletes (P<0.05). There was significant difference before and after regulation of training (P<0.05). The increased levels of BUN were 0.78 mmol/L without significant difference (P>0.05). It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.  相似文献

8-溴-7-甲氧基白杨素诱导白血病Jurkat细胞凋亡   总被引:3,自引:3,他引:0  
目的:研究8-溴-7-甲氧基白杨素(8-bromo-5-hydroxy-7-methoxychrysin,BrMC)诱导人急性T淋巴细胞白血病Jurkat细胞凋亡作用。方法:体外培养Jurkat细胞。FITC标记annexinⅤ/PI染色流式细胞术(FCM)分析细胞凋亡率。ELISA法测定细胞组蛋白/DNA碎片。二氯荧光素二乙酯(2'7'-dichlorofluoresein diacetate,DCFH-DA)荧光探针FCM检测细胞活性氧。结果:BrMC以剂量依赖方式诱导annexinⅤ阳性细胞和组蛋白/DNA碎片增加(P<0.05)。BrMC促进细胞活性氧生成,10 mmol/L N-乙酰半胱氨酸(NAC)预孵育能有效阻断Jurkat细胞活性氧生成,并减弱其诱导细胞凋亡效应。结论:BrMC具有诱导Jurkat细胞凋亡作用,其作用与促进细胞活性氧生成有关。  相似文献
