原发性肝癌肝移植治疗现状与展望

肝移植已成为原发性肝癌治疗的一种重要选择。选择合适的肝癌病例作为移植对象是决定疗效及预后的关键,另外手术禁忌证及术后复发等问题也要慎重考虑。本文就肝癌肝移植治疗方面相关问题近年来的研究情况进行综述。     

山东省中小学生麻疹爆发原因的病例对照研究

为探讨山东省中小学生麻疹爆发的原因 ,采用 1∶2配比的病例对照方法对中小学生麻疹疫苗 (MV)效力进行了研究 ,同时对近年来中小学生MV接种率进行了估算。结果显示 :中小学生MV效力为 74 % ,95 %可信区间为4 7%～ 88% ;小学生MV效力明显高于中学生 ,分别为 82 %和 6 8% ;1999～ 2 0 0 1年学龄儿童的估算接种率分别为75 4 %、75 6 %和 5 5 7%。较低的MV效力和接种率是计划免疫工作薄弱地区中小学生麻疹爆发的主要原因。     

Benign giant cell tumor of bone with osteosarcomatous transformation (”dedifferentiated” primary malignant GCT): report of two cases

 It is not uncommon for sarcomatous transformation of giant cell tumor (GCT) of bone to occur after radiation, but rarely does malignant transformation occur spontaneously, with less than 15 cases reported up to 1995. Only four of these cases have been documented in detail. We report two additional cases of GCT of bone spontaneously transforming or ”dedifferentiating” into osteosarcoma without radiation therapy. The first case is absolutely unique and most interesting in that the dedifferentiation process occurred in one of multiple GCT lung metastases 6 years after successful eradication of a primary tibial tumor. The right lung was resected due to development of a large tumor, and at pathologic examination, demonstrated several small nodules of conventional GCT and a much larger, 14-cm mass composed of a mixture of GCT and high-grade osteosarcoma. The second case involved a physician, who had a large tumor in the sacrum with vague symptoms for 8 years. Open biopsy revealed conventional, benign GCT of bone with a secondary aneurysmal bone cyst. Complete curettage 2 weeks later revealed, in addition to areas of conventional, benign GCT a second component of very high grade osteosarcoma. Both patients died less than 1.5 years from diagnosis. This report of osteosarcomatous transformation of a conventional GCT of bone strengthens the theory that there is a mesenchymal cell line in GCT that may spontaneously tansform to sarcoma.     

Extramedullary plasmocytoma of the bronchial system

Summary. We present a case of primary plasmocytoma of the left upper bronchus. Occlusion led to atelectasis of the left upper lobe and subsequent poststenotic pneumonia. Therapy consisted of local excision of the bronchus and postoperative radiotherapy. This type of lung-conserving therapy in a case of primary plasmocytoma has not been described before.      

66例成人原发肾病综合征临床治疗与病理分析

本对６６例原发肾病综合征患进行病理类型与临床疗效分析。最常见病理类型为系膜增殖性肾炎，占４２．５％，其次为膜性肾病，占３２．５％，ＩｇＡ肾病占１５．０％。微小病变型及系膜增殖性肾炎对激素及免疫抑制剂治疗效果好，膜性肾病治疗效果差。不同病理类型患病理损害程度与疗效相关。伴肾小管间质病变治疗效果差（Ｐ〈０．０５）。ＮＳⅠ型疗效明显优于ＮＳⅡ型（Ｐ〈０．０５）。５０岁以下原发肾病综合征（ＰＮＳ）     

原发全身性癫痫遗传流行病学研究

本文报道１００例原发全身性癫痫家系的遗传流行病学研究结果。先证者一级亲属患病率为６．８６％，二级亲属为１．０３％；分别是对照组一级亲属的１３．８３倍和２．０８倍。原发全身性癫痫的遗传度为：一级亲属０．７５２１±０．０６７８，二级亲属０．３５９２±０．０７４６；加权平均０．５７４３±０．０５０２。说明遗传因素起重要作用。发病年龄影响因素分析表明：原发全身性癫痫有一定年龄依从性。ＥＥＧ家系分析显示，该型癫痫一级亲属癫痫样放电明显高于对照组一级亲属，提示癫痫样放电的遗传倾向。     

A BLIND RANDOMIZED CROSS -OVER TRIAL COMPARING BETAXOLOL WITH TIMOLOL IN OPEN-ANGLE GLAUCOMA AND OCULAR HYPERTENSION

Purpose: To compare the short-term efficacy and side effects of betaxolol and timoloi in treatment of primary open angle glaucoma or ocular hypertension. Methods: Fourteen patients with newly diagnosed early primary open angle glaucoma or ocular hypertension were included.Each patient received 0.5% timoloi and 0.5% betaxolol twice daily for four weeks in two phases. Between two courses of treatment there was four weeks wash out period. At the end of study the effect of these two drugs on intraocular pressure, mean arterial blood pressure,pulse rate,basic tear secretion and ocular symptoms were evaluated and statistically analyzed,using wilcoxon and chi-squar test.RESULTS:The study was performed on fourteen patients with baseline IOP of 26.7 ±1.5 mmHg.After four weeks treatmem,timoiol and betax-olol reduced IOP by 7.8±1.2mmHg or 29% and 6.1±1.3mmHg or 23%, respectively (P<0.001). The difference between two groups was significant(P<0.001). Mean arterial blood pressure was reduced with betaxolol and tim     

肝癌患者血清P-选择素测定及临床意义

目的：研究肝癌患血清P-selection(P-sel)在肝癌复发和转移中的作用。方法：采用ELISA法分别测定原发性肝癌患和对照组血清P-选择素的含量，同时测定AFP含量。结果：肝癌患P-sel含量显高于正常人，且与AFP含量呈线性正相关，术后2周浓度降低；P-sel含量以Ⅰ、Ⅲ和Ⅳ期肝癌患显高于Ⅰ期患；且大肝癌患显高于小肝癌患，有癌栓组、有肝内转移组明显高于无癌栓组和无转移组。结论：P-选择素测定在原发性肝癌的诊断和检测术后复发方面有重要价值，联合检测AFP和sP-sel可提高诊断敏感性。     

Role of citric acid in primary hyperparathyroidism with renal lithiasis

Summary Nephrolithiasis is presented in 18–40% of patients with primary hyperparathyroidism. Our work suggests that citrate, an inhibitor of calcium salts, could be involved in the presence of renal lithiasis because hyperparathyroid stone formers show less citrate elimination than nonstone formers.     

原发睾丸恶性淋巴瘤：（附13例报告）

自1977～1988年我院共收治13例原发睾丸恶性淋巴瘤,占同期睾丸恶性肿瘤的11.5％。本病少见,大部分发生在50岁以上。本文50岁以上者10例,约占80％。此病预后差,本文11侧2年内死亡,占85％。5年生存率仅为15％。本文5例术后辅以放、化疗,8例术后单纯化疗,两者生存期无明显差异,故我们认为手术 化疗为本病的首选治疗方案。
