罗格列酮对糖尿病大鼠肾脏保护作用机制的探讨

目的 探讨罗格列酮对糖尿病大鼠肾脏的保护作用机制。方法 将大鼠分为正常组、糖尿病组、小剂量罗格列酮组、大剂量罗格列酮组。药物干预4周后，检测各组大鼠的血糖（BS）、三酰甘油（TG）、胆固醇（TC）、肌酐（Scr）水平及尿白蛋白定量（24h）。随后处死大鼠，测定肾组织中丙二醛（MDA）含量、总抗氧化能力（T-AOC）及铜锌超氧化物歧化酶（Cu-ZnSOD）、谷胱甘肽过氧化酶（GSH-Px）、核转录因子-κB（NF-κB）的活性。同时留取。肾脏组织作PAS染色行病理检查。RT-PCR和免疫组化法检测。肾组织中单核细胞化学吸引蛋白质1（MCP-1）mRNA及蛋白质的表达。结果 与糖尿病组相比，大剂量罗格列酮干预组BS、TC、TG差异无统计学意义；而。肾组织MDA含量、MCP-1mRNA及蛋白质表达、NF-κB活性差异有统计学意义（P〈0．05），SOD、GSH-Px、T-AOC活性显著上升；肾小球面积及体积减小。结论大剂量的罗格列酮可显著改善糖尿病大鼠的。肾脏损害，其机制可能与其抗氧化，抑制NF-κB活性，降低MCP-1的含量有关。     

子宫内膜息肉中雌、孕激素受体的表达

目的检测子宫内膜息肉雌激素受体(ER)、孕激素受体(PR)的表达,探索子宫内膜息肉形成的原因及机制。方法子宫内膜息肉48例为观察组,正常子宫内膜36例为对照组,采用免疫组化SP法,行半定量分析,检测ER、PR的表达。结果增殖期的息肉组织中PR表达的评分结果为(2.89±2.16),低于增殖内膜的评分(4.04±1.73),差异有统计学意义(P<0.05);分泌期的内膜息肉中ER表达的评分结果为(3.80±1.64),高于分泌期内膜中的评分(2.64±1.45),差异有统计学意义(P<0.05)。结论增殖期的子宫内膜息肉中PR的表达降低及分泌期的息肉中ER表达增高可能参与了子宫内膜息肉的形成及发展。

Clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei infection

Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei （PM） infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results （1） The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture. All the 12 cases （100%） had irregular fever （38-41℃） and enlarged lymph nodes, 8 cases （66%） had skin rashes; 8 cases （66%） had hepatomegaly; 9 cases （75%） had splenomegaly while 8 cases （66%） had anemia. （2） Imaging manifestation： Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 cases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung, and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS （CD4 T lymphocytes 〈50/μ L） with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver, spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of ＂cakes＂.
