垂体腺瘤性男性不育

垂体腺瘤是男性不育的重要病因。现代内分泌和影像学检查能够早期诊断垂体腺瘤引起的男性不育症。针对垂体腺瘤的病因治疗是治疗此类不育症的最佳选择。     

Association of multiple liver cell adenomas with spontaneous intrahepatic portohepatic shunt

The association of multiple liver cell adenomas containing foci of focal nodular hyperplasia with a spontaneous intrahepatic portohepatic venous shunt is reported in a 13-year-old male patient. At least eight nodules less than 10 cm in diameter were recognized and proved by means of surgical resection or surgical biopsies. These lesions were heterogeneous and hypodense on precontrast computed tomographic (CT) scans, and were slightly enhanced after injection of contrast medium. At magnetic resonance (MR) imaging, the signal intensity of these nodules varied. It was either hyperintense or hypointense on T1-weighted SE images. Sonography and angiography demonstrated a portohepatic venous shunt and hepatic arterialization was observed. These findings emphasize the hypothesis that hepatic arterialization may cause the development of liver cell adenomas. Moreover, it is suggested that liver cell adenoma and focal nodular hyperplasia have a common pathogenesis.     

多激素分泌性垂体泌乳素腺瘤的激素分泌谱及克隆分析

目的 对多激素分泌性垂体泌乳素腺瘤的克隆状态以及激素分泌谱进行分析。方法 对26例女性垂体泌乳素腺瘤患者（单激素分泌性PRL腺瘤7例，多激素分泌性PRL腺瘤19例）进行肿瘤标本的免疫组化分析，并且提取DNA行HUMARA分析。结果免疫组化分析提示本组多激素分泌性垂体PRL腺瘤具有10种不同的激素分泌谱，现代分子生物学HUMARA克隆分析提示11／13例（85％）多激素分泌性垂体PRL腺瘤为单克隆起源。结论 结果提示垂体泌乳素腺瘤除了分泌泌乳素外，还可以分泌多种垂体激素，而且绝大多数多激素分泌性垂体腺瘤的起源是单克隆性的。     

结直肠癌肝转移的外科手术治疗

目的评价手术治疗对结直肠癌肝转移病人生存率的影响。方法回顾分析2000年1月1日至2004年12月31日复旦大学附属中山医院收治的363例结直肠癌肝转移病人，其中91例为手术病例，评价手术治疗对生存率的影响。结果160例同时性肝转移病人中手术切除肝转移灶22例（13．8％），203例延时性肝转移病人中手术切除肝转移灶69例（34．0％），两者相比差异具有统计学意义（P〈0．000）。同时性肝转移组手术死亡率（4．5％，1／22）高于延时性肝转移组（2．8％，2／69），两者相比差异有统计学意义（P〈0．05）。以2005年6月31日为随访终点，91例病人随访率100％，手术病人中同时性肝转移组1、3、5年生存率和中位生存时间与延时性肝转移组相似（P〉0．05），但术后复发率较高（36．4％vs21．7％，P=0．03）。363例病人中有36例具有手术指征而未手术病例，其1、3、5年生存率分别为47．9％、5．34％和0，明显低于91例手术病例（80．5％、33．0％和22．7％），（P=0．0034）。应用COX比例风险模型，对所有91例手术病人影响生存的因素进行多因素风险分析，得出手术切缘达1cm（β=-0．8351，P=0．0363）和复发后再次手术（β=-0．9428，P=0．0411）是生存的保护性因素，而术后复发（β=0．6471，P=0．0226）是生存的危险因素。结论手术治疗是结直肠癌肝转移的首选治疗措施，可以明显提高病人的术后生存。

野蔷薇果汁对乌拉坦诱发小鼠肺腺瘤的影响

本研究观察了野蔷薇果汁对乌拉坦诱发小鼠肺腺瘤的影响,并观察了实验第1、2、3、4、5月时小鼠免疫功能及脂质过氧化水平的改变。结果发现,野蔷薇果汁有明显的拮抗乌拉坦诱发小鼠肺腺瘤的作用,对乌拉坦引起的机体免疫状态的降低有拮抗作用,对小鼠自由基及其清除系统也有降低作用。     

Chronic renal failure and its treatment in tuberous sclerosis

BACKGROUND.: Chronic renal failure is rare in tuberous sclerosis, but itsprecise frequency is not known and treatment modalities havenot been evaluated. METHODS.: A questionnaire was addressed to the 260 French dialysis centresand the characteristics of 65 patients with tuberous sclerosisand chronic renal failure were analysed. RESULTS.: In France the approximate prevalence of tuberous sclerosis withend-stage renal failure is 0.7 cases per million and that ofend-stage renal failure in tuberous sclerosis 1 per 100. Tuberoussclerosis with chronic renal failure was more frequent in females(63.1%) and was diagnosed at a mean age of 29 years. Renal impairmentwas the first manifestation of tuberous sclerosis in about halfthe cases. Renal tumours were frequent, with angiomyolipomasin 15 cases (23.1%), cysts in 12 cases (18.5%), and both in35 cases (53.8%). Malignancies were associated in nine cases(13.8%). Nephrectomy was done before dialysis in 21 cases (32.3%),and after the start of dialysis in six cases (9.2%). All butone of the 48 patients with end-stage renal failure were treatedby dialysis; 20 were transplanted, with good results. CONCLUSIONS.: Tuberous sclerosis with end-stage renal failure is rare. Thesepatients require dialysis and renal transplantation, but werecommend binephrectomy after starting dialysis and before transplantation,given the risk of cancer and bleeding related to angiomyolipomas.     

Adenoma malignum (minimal deviation adenocarcinoma) of the cervix responsive to hormonal treatment

Adenoma malignum (AM) is a rare variant of cervical adenocarcinoma with an unfavorable prognosis despite radiation therapy, surgery, or chemotherapy either alone or in combination. Hitherto, however, the effectiveness of hormonal therapy for this condition has not been evaluated. We report on a patient with cervical AM treated with progesterone before surgery. The progesterone therapy resulted in a complete clinical response and partial surgical response. Later on the treatment was changed to tamoxifen because of side effects of the progesterone treatment. The patient is still without evidence of disease 42 months after the start of the hormonal therapy. The progesterone receptor analysis on the biopsy was clearly positive. This is, to our knowledge, the first case of an AM responsive to hormonal treatment. Furthermore, this is the first case of an AM with bone metastases at the time of primary diagnosis.
