335例术后全身炎症反应综合征的临床分析

【目的】了解手术创伤对术后全身炎症反应综合征 (SIRS)的影响。【方法】搜集外科重症监护室 (SICU) 335例患者的术后资料 ,分析不同手术组SIRS发病率 ;手术时间、失血量与SIRS持续时间的关系 ;SIRS持续时间与术后并发症的关系。【结果】术后SIRS发病率为 75 8% ,大手术高达 92 4 % ;无并发症患者失血量与SIRS持续时间呈正相关 (r1=0 783,P<0 0 1) ,手术时间与SIRS持续时间呈正相关 (r2 =0 398,P <0 0 1) ;随着SIRS持续时间延长 ,并发症发病率显著增高 (P<0 0 5 )。【结论】术后SIRS发生、发展与手术创伤密切相关 ;监测SIRS进程有助于及早发现并发症

旋磁场对胆结石病人胆汁中胆红素、钙、胆固醇和pH的影响

目的 探讨旋磁场与大面积静磁场对置对胆结石病人胆汁中总胆红素（BIT）、直接胆红素（BID）、间接胆红素（BII）、钙（Ca）、胆固醇（CH）和pH的影响。方法 旋磁组30例,测定旋磁处理前后65对胆汁样本。空白对照组15例,留取前后30对胆汁样本。将直径12mm圆形稀土永磁片110块,表面磁感应强度210mT,分别间隔10mm贴于210mm×220mm铁皮上形成一个大面积磁板与旋磁头表面静磁感应强度160mT,旋转平均表面磁感应强度100mT呈异名极对置,磁板置肝区背侧,旋磁头置剑突下处理40min。结果 旋磁组胆结石病人胆汁（n=65）:经旋磁场与磁板对置处理前减去处理后差值的x±s和t值分别为BIT41.81±93.52、3.59;BID 13.57±43.70、2.46;BII28.27±61.67、3.32;Ca 0.19±0.31、4.87;CH0.12±0.29、3.36;pH 0.01±0.27、0.30。除pH外,其余各项指标P值均<0.05。对照组胆汁（n=30）:间隔时间前后差值的x±s和t值分别为BIT4.42±22.05、1.14;BID2.40±12.37、1.06;BII2.52±46.27、0.30;Ca0.01±0.18、0.50;CH0.03±0.15、0.94;pH 0.009±0.06、0.84。P值均>0.05。结论 在本项磁场类型、强度和时间处理条件下,旋磁场与磁板对置能明显影响胆结石病人胆汁中的BIT、BID、BII、Ca和CH的浓度变化,且有显著降低的作用。

放射线联合p53基因及内皮抑素治疗小鼠前列腺癌皮下移植瘤

Objective To test the hypothesis that p53 gene therapy combined with endostatin can enhance tumor response to radiation therapy of RM-1 mouse xenograft prostate cancer and to investigate its mechanism. Methods A mouse prostate cancer model was established. Then mice with xenograft tumor were randomly divided into group A (control), B (radiation), C (radiation and rAdp53), D (radiation and rh-endostatin) and E (radiation and rAdp53 and rh-endostatin). On day 1, rAdp53 was injected intra-tumorously with 1 × 1010 vp per animal to group C and E. From day 1 to 14, rh-endostatin was given 15 mg/kg intraperitoneally daily to group D and E. On day 4 single fraction of 15 Gy was given to tumors in groups B, C, D and E. Normal saline was injected intra-tumorously or intraperitoneaUy accordingly as control. No treatment was done to group A. Tumor volume was measured daily. Samples were collected on Days 5, 10 and 15. Ki67, CD31, p53 and VEGF were detected by means of immunohistochemistry. Results (1) Radiation alone, radiation combined with intra-tumorous injection of Adp53 and/or intraperitoneal injection of rh-endostatin resulted in tumor growth arrest of RM-1 cells in vivo (P = 0.000). Radiation combined with both rAdp53 and rh-endostatin was the most effective treatment (P < 0.05). (2) All the four treatment groups had a decreased expression of mutant type P53 (P = 0.000). The expression of Ki67 in groups B and C were equal (P 0.05) and increasing (P = 0.000), respectively. Group D had a up-down-up curve (P < 0.05), but group E had a up-down one. On day 5 the expresion of VEGF in group E was the lowest (P < 0.05). An increased expression of MVD compared with the control was shown, and MVD in groups C, D and E were always higher than that in the control (P < 0.05). Conclusions The limitation of radiotherapy could be overcome by combination with beth p53 gene therapy and endostatin on the growth of mouse prostate cancer cell. Radiation, rAdp53 and endostatin have their own role but they can be interacted with each other.
