术前炎症和营养预后指数与结直肠癌近期疗效

目的探讨结直肠癌患者术前炎症和营养预后指数（prognostic inflammatory and nutritional index,PINI）水平与近期疗效的关系。方法前瞻性纳入2009年4～6月期间经病理检查诊断为结直肠癌的住院患者。所有患者均于术前3d测定血清α1-酸性糖蛋白、C-反应蛋白、白蛋白和前白蛋白水平,并以此计算术前PINI值。分析术前PINI水平与患者病理分期、术后并发症、生活质量及复发转移的关系。结果本研究共纳入结直肠癌患者38例,均接受了根治性手术治疗,术前PINI水平平均为2.17±1.27。术前PINI水平与病理TNM分期及M分期有关：Ⅳ期患者的PINI水平明显高于Ⅰ、Ⅱ及Ⅲ期（P〈0.001）,M1期患者的PINI水平亦明显高于M0期（P〈0.001）。术前PINI水平与患者术后并发症的发生无关（P〉0.05）。术前PINI水平与患者术后的厌食情况、饮食总体情况及生存质量的总体评估水平有关：饮食不正常者或有厌食情况者,其PINI水平明显高于饮食正常者（P=0.020）或无厌食情况者（P=0.020）;生存质量＂差＂者,其PINI水平明显高于生存质量＂好＂（P=0.020）及＂一般＂（P=0.025）者。结论术前PINI可以作为结直肠癌患者短期预后的评估指标之一。     

术前血清淀粉样蛋白A水平对低位局部进展直肠癌手术方案选择的价值

目的 探讨术前血清淀粉样蛋白A(SAA)水平对低位局部进展直肠癌(LLARC)手术方案选择的价值.方法 回顾性分析于四川大学华西医院住院的52例LLARC患者的临床资料,根据手术方式的不同分为根治手术组(n=35)和姑息手术组(n=17).所有患者术前采静脉血测定SAA水平.结果 LLARC手术方案的选择与术前SAA水平有关(P=0.004),而与直肠癌病理学特征和术前影像学分期无关(P>0.05).术前SAA水平升高(≥10.5 mg/L),显著增加了LLARC选择姑息手术治疗的风险(OR=7.47, 95% CI: 1.62～34.40, P=0.010).结论 高SAA水平是预测LLARC患者行姑息手术风险的有效指标,这对于指导外科手术决策和辅助治疗的制定具有临床价值.

目的目的了解“5·12”四川地震中受灾人员的心理健康状况。方法使用SCL-90对四川省各重灾区转移到当地民政系统安置点的灾区人群中163名人员进行调查研究。结果受灾人员SCL-90的强迫症状、人际关系、忧郁、恐怖分值均高于全国常模（P〈0．05）;在SCL-90诸因子分中强迫症状、人际关系、忧郁、恐怖因子分值女性灾民高于男性（P〈0．05）。结论随着全球气候的复杂多变,自然灾害的增多,注重心理危机干预,能够使人们尽早恢复心理健康,增加生活的信心。     

肿瘤相关基因rassf1a在肾细胞癌及癌旁肾组织中的表达

目的:探讨肾癌、癌旁肾组织中肿瘤相关基因rassf1a的表达水平及差异及与临床分期的关系.方法:应用实时荧光定量PCR方法检测rassf1a基因在30例肾细胞癌组织及癌旁肾组织中的表达,并比较不同临床阶段其表达的差异.结果: rassf1a基因在肾癌组织中平均表达明显低于在癌旁肾组织中的平均表达.rassf1a基因在肾癌组织中的表达降低与临床分期无关.结论:肾癌的发生、发展可能与rassf1a基因有关.     

Value of abdominal ultrasound scan, CT and MRI for diagnosing inferior vena cava tumour thrombus in renal cell carcinoma

Background We used abdominal ultrasound scan （USS）, computed tomography （CT） and magnetic resonance imaging （MRI） findings in venous spread of renal cell carcinoma （RCC） to determine the superior extent of inferior vena cava （IVC） thrombus and IVC wall invasion and compared them with surgical and pathological reports. Methods From January 1999 to August 2007, 25 patients were diagnosed with RCC with IVC tumour thrombus. Before their operation, all patients had USS, contrast enhanced CT and MRI to find the superior extent of tumour thrombus and IVC wall invasion. All postprocessing techniques were performed by experienced radiologists. Two pathologists reported on all pathology specimens. The superior extent of tumour thrombus was confirmed by the senior surgeon at each operation, using the levels of thrombus defined according to 2004 Mayo Clinic classification. The radiographic results were compared with surgical and pathological findings. Results All patients had radical nephrectomy and tumour thrombus excision. Eight patients had RCC on the left side and 17 on the right side. According to the clinical and pathological findings, 6 patients had level I tumour thrombus, 9 level II, 5 level III and 5 level IV. Six patients had IVC wall invasion. No patient had evidence of lymph node or distant metastases. Of the 25 patients, USS correctly diagnosed the superior extent of tumour thrombus in 18/25, CT 23/25 and MRI 23/25. USS found 1 case of IVC wall invasion preoperatively. Conclusions Multidectector computed tomography and magnetic resonance imaging are comparable and more effective than abdominal ultrasound in diagnosing inferior vena cava tumour thrombus in renal cell carcinoma. None of the three methods can detect inferior vena cava wall invasion.     

Recalling the glorious past six decades and foreseeing a promising new century — the 60-year development of Chinese urological surgery

Urological surgery did not take shape as a discipline until the establishment of the new China. From small and weak to large and strong, and with the painstaking efforts of several generations since the inception of reform and opening-up policy, China＇s urological surgery has developed into a significant subject subordinated to clinical medicine.     

Imaging features of central nervous system haemangiopericytomas

Intracranial and spinal haemangiopericytomas are uncommon, durally based tumours. They macroscopically resemble meningiomas but are distinct histologically, have a more aggressive natural history and require different management. We present a pictorial review illustrating the radiological manifestations of these tumours that will aid in their preoperative identification.     

Epstein Barr virus latent membrane protein-1 in Hodgkin's lymphoma in Nigerians

Background

The burden of lymphomas on the health care system in Nigeria is enormous. Correct diagnosis and identification of aetiological factor are important steps in reducing this burden.

Methods

Eight cases diagnosed as HL within a period of six years at the Obafemi Awolowo University teaching Hospital, Ile-Ife, Nigeria by haematoxylin and eosin (Hand E) only were immunophenotyped using the indirect immunoperoxidase method. Epstein-Barr virus latent membrane protein-1 (LMP-1), CD15 and CD30 immunohistochemistry was also performed. The clinical characteristics of each patient were documented.

Objectives

To document the frequency of involvement of Epstein-Barr virus in cases of HL seen in a university hospital in Nigeria.

Results

Out of the eight cases diagnosed by H&E as HL immunophenotyping showed only five were HL. The rest were non-Hodgkin''s lymphoma (2 diffuse large B-cell and 1 null cell ALCL). All were cases of classical HL with 60% being of the mixed cellularity (MC) subtype. There were 2 males and 3 females with ages ranging from 7 years to 40 years. All presented with cervical lymphadenopathy and three had splenomegaly in addition. 60% of the tumour was EBV positive, all of the MC subtype. Three patients had chemotherapy. Eventually all were lost to follow-up. There was no case of the nodular lymphocyte predominance variant.

Conclusion

Mixed cellularity is the most common subtype and is the only subtype associated with EBV positivity in this study. Epstein-Barr virus probably plays an important role in the aetiology of HL in Nigerians.Running title: Epstein-Barr virus, Hodgkin''s lymphoma in Nigerians     

胰岛素抵抗和非胰岛素抵抗多囊卵巢综合征患者的对比研究

目的探讨多囊卵巢综合征(PCOS)胰岛素抵抗(IR)患者的临床特征。方法选取48例PCOS患者,将稳态模型胰岛素抵抗指数(HOMA-IR)>3.8或葡萄糖及胰岛素曲线下面积比值(AUC葡萄糖/AUC胰岛素)<1.0的PCOS患者作为IR组(30例),上述两个标准均不符合的PCOS患者作为非IR组(18例)。比较IR组和非IR组患者的体质指数(BMI)、血脂水平及各项性激素水平。结果 (1)IR组患者BMI及肥胖者所占比例均显著高于非IR组,差异有统计学意义(P<0.05);(2)IR组患者三酰甘油、载脂蛋白B水平均显著高于非IR组,而高密度脂蛋白、载脂蛋白AⅠ水平则显著低于非IR组,差异均有统计学意义(P<0.05);(3)IR组患者黄体生成素水平显著低于非IR组,睾酮水平则显著高于非IR组,差异亦有统计学意义(P<0.05)。结论 (1)存在IR的PCOS患者更容易出现血脂异常;(2)PCOS患者性激素有不同改变,存在IR者以睾酮升高为主而非IR患者则以黄体生成素升高为主。
