卡介苗对体外培养膀胱癌细胞株的直接作用和形态学观察

我们用卡介苗（ＢＣＧ）直接作用于体外培养膀胱癌细胞株，用扫描电镜和相差显微镜观察，癌细胞形态学发生明显变化，癌细胞表面结构损伤严重，微绒毛和长突起消失，残存畸变，小球密集成片，肿瘤表面结构与胞体分离，癌细胞生长抑制曲线表明，癌细胞的生长抑制率随着时间延长和ＢＣＧ浓度增大而增高。实验证明，ＢＣＧ对膀胱细胞有直接损伤作用。     

膀胱癌手术切除及灌注治疗疗效分析

目的 探讨膀胱癌术后膀胱局部灌注辅助治疗疗效。方法 膀胱癌术后用以卡介苗与丝裂霉素行膀胱灌注。结果 12例卡介苗灌注，3例复发，复发率25％。12例丝裂霉素灌注，1例复发，复发率8．3％。结论 膀胱癌术后卡介苗与丝裂霉素行膀胱灌注治疗，丝裂霉素复发率低，副作用小，是一种有效的治疗方法。     

膀胱癌68例临床报告

本文分析68例膀胱癌的临床资料,按Jeweett-Marshall法分期,除D期病人行膀胱全切除或输尿管皮肤移植术、因肠代膀胱术外,其余均行膀胱部分切除术,术后用化学药物膀胱灌注:膀胱全切除术的5年生存率为47.06%,膀胱部分切除术的5年生存率为58.82%;术后复发率为20.58%。并对术后复发的原因进行分析和讨论。     

羟基喜树碱灌注预防膀胱癌复发的临床观察

目的：探讨膀胱灌注羟基喜树碱(HCPT)预防肿瘤复发的临床疗效。方法：对36例膀胱肿瘤患术后作HCPT 10mg加生理盐水40ml膀胱灌注治疗。结果：获得定期随访病例33例，随访时间6—54个月，平均36．5个月。1例在15个月时复发，5例在26—42个月中复发，复发率为18．1％。结论：膀胱肿瘤术后膀胱灌注HCPT治疗效果可靠，副作用微小，无全身性化疗反应发生。     

尿中脱落细胞检查对膀胱癌诊断的临床分析(附6例报告)

<正> 膀胱癌在泌尿肿瘤中多见,临床表现呈多样性,易误诊或漏诊。对中年以上无痛性血尿患者,进行尿中脱落细胞检查尤为重要。对确诊前的实验室检查进行回顾认为,无痛性中老年血尿患者,除鉴别诊断排除结核菌感染外,反复的进行细胞脱落检查,对早期明确诊断有极重要意义。现报告如     

The effect of Fufangkushen on gastric cancer cell killing by lines SGC-7901 human γδT cell

Objective To explore the effect of Fufangkushen on gastric cancer cell killing by human γδT cells. Methods Isopentenyl pyrophosphate method was used to amplify human peripheral blood γδT cells in vitro. Fufangkushen at various concentrations was used to induce γδT cells and gastric cancer cell lines SGC-7901 for 24 hours, MTr assays was used to detect inhibitory effect of Fufangkushen on these cell lines, LDH assays was used to measure the cytotoxic activity of γδT cells, and flow cytometry was used to detect apoptosis of γδT cells and SGC-7901 before and after the treatment. Results Ten days after cultivation, proliferation ra-tio of γδT cells increased from 4.21% to 70.35% and CD44 was up to 94.0%. Inhibitory rate of Fufangkush-en on SGC-7901 at various concentrations was significantly higher than that on γδT cells (22.3% vs-22.4%, P<0.05). The negative inhibitory ratio on γδT cells showed a dose-dependent manner with Fufangkushen's concentrations ranging from 1/5 to 1/400. γδT cells cytotoxic activity to SGC-7901 induced by Fufangkushen for 24 h was higher than control group, (83.6% vs 71.2%, P<0.05). Apoptotic rate was significantly lower in γδT cells than in SGC-7901 (4.64% vs49.23%, P<0.05). Conclusion Fufangkushen, within routine concentration ranges, can promote γδT cells' proliferation, inhibit tumor cell growth and enhance γδT cells' cytotoxic activity. This may be beneficial to tumor adoptive immunotherapy and provide evidence for the appli-cation of Fufangkushen in the treatment of tumors.     

白血病骨髓瘤单抗对白血病细胞株细胞内环核苷酸的影响

本文应用放射免疫测定法，检测了单克隆抗体作用于相应白血病瘤细胞后细胞内ｃＡＭＰ，ｃＧＭＰ的含量变化。结果发现：抗原、抗体比例在８０：１时经ＭｃＡｂ作用１６－２４ｈ后，瘤细胞内ｃＡＭＰ含量明显高于对照组，ｃＧＭＰ含量明显低于对照组（Ｐ＜０００２－０００１）。从而提示：ＭｃＡｂ可通过对细胞膜作用，调控细胞内ｃＡＭＰ和ｃＧＭＰ的水平。本文还对ＭｃＡｂ作用深度及作用时间进行了探讨。     

介入联合手术治疗膀胱癌32例疗效分析

目的观察髂内动脉灌注化疗联合手术治疗膀胱癌的疗效。方法对32例中晚期膀胱癌先行介入治疗,再手术切除。结果32例膀胱癌完全缓解(CR)率为71．9％。结论介入治疗中晚期膀胱的手术提供了良好基础,对一部分原本行扩大切除术甚至全切的患实行单纯部分切除术,从而保留了膀胱生理功能,有助于提高患生活质量,延长生命。
