目的:评价舍尼通与抗生素联合用药治疗慢性非细菌性前列腺炎的有效性及耐受性。方法:采用双盲、平行对照、多中心临床试验研究方法,通过Stam ey试验、前列腺按摩液(EPS)常规及美国国立卫生院慢性前列腺炎症状评分(NIH-CPSI),筛选出160例慢性非细菌性前列腺炎患者,随机分为试验组(80例,脱落1例)和对照组(80例)。试验组前4周合用舍尼通和左氧氟沙星,后4周单用舍尼通,服用剂量为舍尼通2次/d,1片/次,左氧氟沙星2次/d,0.1 g/次;对照组方法同上,仅将舍尼通换为安慰剂。所有患者均行入组前、治疗第4周和第8周随访并行NIH-CPSI评分、EPS等检查及药物不良反应的评估。结果:治疗后4周和8周,试验组疼痛评分降低分别为3.34±2.45,4.33±3.13,排尿评分降低分别为2.22±1.79,2.77±2.04;对照组疼痛评分降低分别为2.28±2.42,3.30±3.29,排尿评分降低分别为1.24±1.67,1.83±2.25。两组治疗前后的自身对比均差异有显著性(P<0.01),生活质量影响评分差异也有显著性(P<0.05)。组间比较,试验组较对照组第4周和第8周疼痛和排尿评分差异均有显著性(P<0.01或P<0.05)。两组治疗前后白细胞、卵磷脂小体差异无显著性(P>0.05),对药物的耐受性差异无显著性(P>0.05),无严重不良反应事件发生。结论:舍尼通与抗生素联合用药方案能更有效地缓解慢性非细菌性前列腺炎患者的疼痛不适症状和排尿症状,耐受性好,值得在临床上推广应用。     

小肠肿瘤罕见原因

小肠是消化道中最长的一段,是食物消化、吸收和能量转化的主要场所,但小肠肿瘤的相关研究却鲜有报道。原发性小肠恶性肿瘤在临床少见,由于缺乏典型临床表现及有效治疗手段,导致预后极差。小肠巨大的表面积及上皮快速更新的状态与小肠肿瘤的低发病率显然相悖。小肠肿瘤较低的发病率这一科学问题已成为困扰医学科学领域的世纪之谜。本综述主要从小肠独特的生理屏障、基因调控系统、共生菌群及黏膜免疫系统四个方面剖析小肠肿瘤罕见的原因。理解小肠精密的调控机制将为研究衰老、肠道菌群及肿瘤防治提供新思路。本文基于以往研究,结合最新进展对小肠肿瘤流行病学现状、低发病率的可能原因及其对肿瘤防治的启示进行综述。

Sexual precocity: sex incidence and aetiology

The aetiology of 197 girls and 16 boys presenting with sexual precocity was reviewed. Ninety one girls and four boys had central precocious puberty (M:F 23:1); a cause was identified in all the boys but in only six girls. All boys with precocious puberty need detailed investigation; in girls investigation should be based on clinical findings, particularly the consonance of puberty.     

The Long Evans Cinnamon (LEC) rat develops hepatocellular damage in the absence of antimicrosomal antibodies

Long Evans Cinnamon (LEC) rats are an inbred strain with a mutation affecting a copper transporter. As a result, hepatic copper levels rise and the rats spontaneously develop hepatitis that is fatal in about 40% of the rats. The rats that die have been reported to develop anti-microsomal antibodies, most frequently against protein disulfide isomerase (PDI), prior to the onset of liver damage. The association between the presence of antibodies and death of the LEC rats, along with the detection of antibodies prior to the detection of liver damage suggested that the antibodies may have a role in the pathogenesis of liver damage. The objective of this study was to more clearly delineate the temporal relationship between antibody production and the onset of liver damage and copper accumulation. Serum was screened for the presence of anti-microsomal antibodies by immunoblotting. Liver damage was assessed by serum biochemistry and histological examination on rats between 6 and 12 weeks of age (four per group). Copper accumulation in the liver was determined by biochemistry and histological examination. Evidence of liver damage was detectable by serum biochemistry and histopathology by 11.5 weeks. Copper was rarely detected in hepatocytes, although it was detected in macrophages. Sera from only one of seven rats with evidence of liver damage had detectable anti-microsomal protein antibodies. The protein recognized was not PDI. The development of anti-microsomal autoantibodies did not precede the development of significant liver damage, suggesting that they play only a secondary role, if any, in the pathogenesis of hepatitis in this rat strain.
