肾混合性上皮间质肿瘤和成人囊性肾瘤的临床病理学观察

Objective To study the clinicopathologie features,immunophenotype and differential diagnosis of mixed epithelial and stromal tumor of kidney ( MEST) and adult cystic nephroma ( CN).Methods Five cases of MEST and 4 cases of CN were retrospectively analyzed.Immunohistochemical study was carried out and the literature was reviewed.Results All of the five patients with MEST were females.Their median age was 45 years.For CN,there were 3 males and 1 female and their median age was 41 years.All patients presented with loin pain and hematuria.On gross examination,MEST was well-circumscribed but non-encapsulated.There was no evidence of haemorrhage or necrosis.Three of the cases were solid in nature.One was composed of a mixture of solid and cystic elements,while the remaining case showed a multicystic cut surface bridged by thick fibrous septa.On the other hand,CN were well-circumscribed and encapsulated.They were multiloculated cystic in nature.The cystic spaces were separated by thin septa and there was no significant solid or necrotic component.Histologically,MEST consisted of proliferation of cystically dilated glands admixed with spindly stromal cells with various cellularity and growth patterns.Both the glandular and stromal elements were well-differentiated with no cytologic atypia identified.The glandular structures in 2 of the cases were partially lined by endometrial or tubal epithelium.In contrast,the thin-walled cystic spaces in CN were lined by a single layer of epithelium.Immunohistochemical　study showed that the epithelial cells were positive for pan-cytokeratin and epithelial membrane antigen.The spindle cells in MEST expressed vimentin (5/5 ) ,smooth muscle actin (3/5 ),desmin (4/5 ),CD10 (5/5),estrogen receptor (4/5) and progesterone receptor (4/5).They were negative for HMB45,CD34,CD117 and S-100 protein.On the other hand,the spindle cells in CN were variably positive for vimentin (4/4),smooth muscle actin (4/4),desmin (1/4),estrogen receptor (3/4) and progesterone receptor (1/4).They were negative for CD10,HMB45,CD34,CD117 and S-100 protein.Conclusions Both MEST and CN are uncommon renal neoplasm.Most of them run a benign clinical course.The stromal cells in MEST show smooth muscle or myofibroblastic differentiation.Areas demonstrating Miillerian features also existed in some cases.MEST and CN share overlapping histological and immunohistochemical features,and may represent spectrum of the same group of lesions.

腹腔镜微创与传统开腹胆道取石治疗胆总管结石的效果分析

目的比较腹腔镜微创与传统开腹胆道取石治疗胆总管结石的效果及对患者机体氧化应激和免疫功能的影响。方法选择该院2015年7月-2017年12月收治的90例胆总管结石患者,利用随机数字表将其分成微创组与开腹组两组,每组各45例。其中微创组给予腹腔镜联合胆道镜治疗,开腹组给予传统开腹胆道取石术治疗,比较两组手术疗效及手术前后氧化应激指标[超氧化物歧化酶(SOD)、丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-Px)]和免疫功能指标[CD3~+、CD4~+、CD8~+T细胞百分率及CD4~+和CD8~+T细胞比值(CD4~+/CD8~+比值)]的变化。结果微创组手术时间和术中出血量明显低于开腹组(P 0.05),两组结石取净率比较,差异无统计学意义(P0.05)。微创组术后肠鸣音恢复、肛门排气和住院时间明显低于开腹组(P 0.05)。微创组术后12 h时视觉模拟评分(VAS)、术后镇痛药使用率和并发症发生率明显低于开腹组(P 0.05)。微创组手术前后血清SOD、MDA和GSH-Px比较,差异无统计学意义(P0.05);开腹组术后第1天时血清SOD和GSH-Px活性明显低于术前,MDA水平明显高于术前(P 0.05)。两组术后第1天时外周血CD3~+、CD4~+、CD8~+及CD4~+/CD8~+比值明显低于术前(P 0.05),其中开腹组降低更明显(P 0.05)。结论腹腔镜微创与传统开腹胆道取石治疗胆总管结石均能取得较好的取石效果,但腹腔镜微创手术对机体创伤更小,不会引起明显的氧化应激反应,对机体免疫功能影响小,术后恢复快。     

不同介入模式在肝癌治疗中的应用分析

目的探讨不同介入模式在肝癌治疗中的应用分析。方法选取我院肝癌患者130例,将其分为三组,其中,一组患者采用经肝动脉化疗栓塞术(TACE)治疗,二组患者采用肝门静脉化疗栓塞术(PVCE)治疗,三组患者在前两组患者治疗的基础上进行经皮肝穿刺乙醇消融(PEI)治疗,对比分析三组患者的治疗效果。结果一组治疗总有效率为27.5%,二组治疗总有效率为35%,三组治疗总有效率为92%,三组相对于一、二组来说治疗效果更佳,差异具有统计学意义(P0.05)。结论肝动脉化疗栓塞术、肝门静脉化疗栓塞术和经皮肝穿刺乙醇消融治疗相结合治疗肝癌患者,能够有效提高患者治疗效果,稳定患者病情。     

联合介入治疗大肝癌的临床疗效分析
