薏苡仁提取物对围手术期宫颈癌组织Langerhans细胞的影响

【摘要】   目的 观察薏苡仁提取物(康莱特)注射液对围手术期癌组织Langerhans细胞(LC)的影响。方法61例宫颈癌患者按照自愿的原则随机分为治疗组32例和对照组29例,治疗组患者围手术期采用康莱特注射液治疗,采用免疫组化S-P法观察手术切除宫颈癌组织内LC的变化及形态特征,并与29例对照组进行比较。结果与对照组比较,治疗宫颈癌组织内LC显著增多(P0.05),且与癌细胞密切接触,反映对癌细胞杀伤作用增强。随着肿瘤分化程度降低,浸润深度增加,LC及间质淋巴细胞数量明显减少(P0.01),显示肿瘤对机体免疫功能的损害。结论 薏苡仁提取物具有抗癌作用,可改善宫颈癌患者围手术期机体的免疫功能,提高手术治愈率,延长生存期。

Abstract:ObjectiveTo study the influence of jobstears seed extract (Kang Wright) inoculation fluid on Langerhans cells (LC) in tissue of cervical carcinoma during perioperative period. Methods61 cases with cervical carcinoma during perioperative period were divided at random into the experimental group of 32 cases and the control group of 29 cagas.Patients of the experimental group were treated with jobstears seed extract inoculation fluid, and their characteristics in tissue of cervical carcinoma were explored with the S-P immunohistochemical method.ResultsThe expression of LC in tissue of cervical carcinoma was higher in experimental group than that in control group (P0.05), and more cells contacted with cancer cells so that the effect against cancer increased. With the decrease of cell differentiation degree, the deeper the tumor infiltrated, the less LC and lymphocytes could be found in interstitium (P0.01). ConclusionJobstears seed extract has an anti—carcinoma effect.The immune function, cure rate and life span in patients with cervical carcinoma can be improved by immune regulating treatment during perioperative period.

宫颈癌是女性生殖系最常见的恶性肿瘤,严重威胁着妇女的健康。现代科学研究已证实,肿瘤的发生、治疗、预后和康复与机体免疫状态都有密切关系。因此,维持一个良好健全的免疫状态对于机体抵御肿瘤的侵袭和危害以及对肿瘤患者的生存和生活质量都至关重要。薏苡仁提取物治疗大肠癌取得良好效果[1] 。本实验通过观察薏苡仁提取物对围手术宫颈癌患者癌组织内LC的影响,观察薏苡仁提取物宫颈癌的疗效。

1 材料与方法。

1.1 材料来源。

61例宫颈癌患者,术前均经活检,病理诊断为宫颈鳞癌,随机分为两组,治疗组32例,年龄35~72岁,平均58.84岁;对照组29例,年龄43~75岁,平均57.4岁。两组均行宫颈癌根治切除术。每例于癌中心取材1块,癌旁四周1 cm处取材4块,每块1 cm×1 cm×0.5 cm,10%缓冲福尔马林固定制成蜡块。切片厚4 μm,贴片4张,分别做HE染色及S—100蛋白S-P免疫组化染色。两组在年龄、性别、治疗方法、病理分级等方面均无显著性差异,具有可比性,P>0.05。

1.2 药物用法及观察指标。

1.2.1 药物用法。

治疗组于术前1周注射康莱特注射液,100 mg/次,1次/d;对照组注射生理盐水,100 mg/次 ,1次/d,术后继续注射1周,评价疗效。对照组其它治疗方法均与治疗组相同。

1.2.2 观察指标。

HE染色光镜观察癌细胞分化程度,浸润深度及间质淋巴细胞浸润情况,S—100蛋白S-P法免疫组化染色,详细观察LC细胞的形态分布,并通过油镜观察LC与肿瘤细胞之间的关系,每张切片挑选10个阳性细胞较密集的高倍视野,每个视野计数100个细胞并计算阳性细胞的数量,求其算术平均值,将0~2/H定为(+),将3~4/H定为(+ +),5/H定为(+ + +)。癌组织内LC细胞,散布定为(+),呈灶状聚集定为(+ +),生发中心形成定为(+ + +)。

1.2.3 统计学处理 采用χ2检验。
