78例胃窦癌的治疗分析

自１９８８年２月至１９９２年８月期间手术治疗的７８例胃窦癌患者进行了回顾性分析，手术后肿瘤复发的情况，与十二指肠断端有无癌细胞残存密切相关，并发现于幽门环下切断十二指肠少于３ｃｍ者有癌细胞残存达３４％，切除十二指肠达３ｃｍ者，无论肿瘤分化程度如何，恶性程度高低，切除断端均无癌细胞残存，手术后辅以化疗，对于病人的预后有一定提高。本组随访到的５９例病人中，接受化疗的３３例，在２年３个月至６年１个月内死亡７例（２１．２％），未接受化疗的２６例，在５个月至３年８个月内死亡的２６例，在５个月至３年８个月内死亡９例（３５％）。     

Anti-avian antibodies and rheumatoid factor in pigeon hypersensitivity pneumonitis

BACKGROUND: Although several immunological abnormalities may be present in pigeon hypersensitivity pneumonitis (HP), few specific hallmarks have been described. OBJECTIVE: To determine whether the presence of rheumatoid factor (RF) could be useful to discriminate pigeon HP from asymptomatic breeders (AB) and other interstitial lung diseases. METHODS: Fifty-three patients with pigeon HP, 47 AB, 31 idiopathic pulmonary fibrosis (IPF) patients and a rheumatoid arthritis (RA) group were studied. IgM RF was determined through enzyme-linked immunosorbent assay (ELISA) and western blot using human IgG and IgG Fc fragment as antigens. IgG and IgA anti-avian antibodies (AA) against pigeon serum antigen were also measured. The use of F(ab')2 fraction of peroxidase-labelled anti-human immunoglobulins prevented endogenous interferences. Possible cross-binding of RF with avian antigens and the reactivity against human IgG by AA were studied. RESULTS: RF tests were frequently positive in HP (52.8%) in comparison to AB (4.2%) and IPF (12.9%; P = 2.6 x 10-10 and 4.1 x 10-5). Therefore, the presence of RF in pigeon HP showed a sensitivity of 52% and was highly specific considering the results of AB and IPF (95 and 87%, respectively). The RA group revealed positive RF but negative AA tests. RF activity was confirmed through western blot using purified IgG Fc fragment. Overlapping levels of IgG and IgA AA were found in HP and AB. The frequency of AA was low in IPF. The cross-reaction of RF with avian antigens was excluded, and no reactivity against human IgG by AA was detected. Other endogenous interferences were ruled out. CONCLUSION: No single immunological test may definitively distinguish pigeon HP from AB and other interstitial lung disorders; however, positive RF, together with high AA levels, seems to be useful in differentiating the diagnosis.     

Centralisation of services for the management of ovarian cancer: arguments for

The recommendation in 1999, by the National Health Service Executive (NHSE) that the management of gynaecological cancer be centralised, led to a reorganisation of services for women with gynaecological malignancies. Debate has continued about the feasibility and benefits of ovarian cancer centralisation particularly because its insidious presentation can make it difficult to identify women with ovarian cancer before surgery. Despite this, there is clear evidence that centralisation is advantageous to women in terms of quality of life, morbidity and survival.     

关节液检查的临床意义

Rheumatoid arthritis and membranoproliferative glomerulonephritis: an unusual case

SUMMARY: Renal involvement is not uncommon in rheumatoid arthritis (RA). Many RA patients have renal dysfunction either secondary to the drugs used to treat arthritis or because of the chronic inflammation. Renal pathologies have often included amyloidosis, drug-related renal disease and mesangial glomerulonephritis. However, membranoproliferative glomerulonephritis has only been rarely reported. We report a case of rheumatoid arthritis associated with membranoproliferative glomerulonephritis that rapidly progressed to end-stage renal disease.     

带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎

目的：阐明带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎的疗效。材料和方法：对４２例４８髋晚期类风湿性髋关节炎病人采用以旋股外侧血管降支为蒂的股前外侧筋膜瓣移植行患髋成形术。结果：术后随访４～１０．５年，平均４．５年，髋关节活动范围术前平均１６．５°，术后２２８．６°，按照Ｃｈａｒｎｌｅｙ和吴之康人工髋关节置换术后的疗效评定标准，优良２９髋、很好１３髋、好６髋，尚可、差、很差无。结论：患者年龄在１５～４０岁之间为合适的治疗年龄。与人工髋关节置换术相比，本方法对髋关节正常结构破坏小；一旦手术失败仍可选用其它治疗方法弥补；且并发症少、费用低、远期效果好。

Lipoprotein lipase in relation to inflammatory activity in rheumatoid arthritis

Objective. To evaluate the impact of chronic inflammation on lipoprotein lipase (LPL) levels and triglyceride metabolism in patients with rheumatoid arthritis (RA). Design. Plasma levels of LPL activity and mass before and after heparin were determined in post-menopausal women with active RA and in controls. The results were related to lipid levels and inflammatory variables. The LPL activity and mass together with triglyceride levels were also measured before and 6 h after an oral fat load. Setting. The study was performed on in- and out-patients at a University Rheumatology clinic. The controls came from the same reference area. Subjects. Altogether 17 consecutive post-menopausal female patients with RA and 16 age and sex matched controls were enrolled for the initial determination of LPL. Fifteen of the patients and 15 of the controls agreed to take part in the fat load. Of these, one patient and one control were excluded. Main outcome measures. LPL determination: basal levels and post-heparin levels of LPL activity and mass. Correlations between LPL and blood lipids (cholesterol, triglycerides), lipoprotein levels (high density lipoprotein, HDL; low density lipoprotein, LDL), erythrocyte sedimentation rate (ESR) acute phase proteins (orosomucoid, haptoglobin, fibrinogen mass) and cytokines (tumour necrosis factor α, TNF-α; interleukin 1β, IL-1β; and interleukin-6, IL-6). Fat tolerance test: LPL activity, mass and triglyceride levels before and 6 h after a per oral fat load. Results. Pre-heparin LPL mass (P<0.01) and activity (P<0.01) were significantly lower in the rheumatoid patients. Pre-heparin LPL mass showed no correlation to the lipid levels, but an inverse correlation to several inflammatory parameters; it was significant for orosomucoid (r_s=?0.63, P<0.05) and C-reactive protein (CRP) (r_s=?0.54, P<0.05) and close to significant for haptoglobin (r_s=?0.48, P=0.087) and IL-6 (r_s=?0.52, P=0.061). Six hours after a lipid load the LPL activity and mass were significantly lower in RA (P<0.05 and P<0.01, respectively) but the triglyceride level was not significantly different compared to controls. Conclusion. An inverse relationship exists between inflammatory status and pre-heparin LPL mass. Pre-heparin LPL mass reflects mainly the inactive monomeric fraction of LPL. This has been shown to hinder the uptake of remnant lipoprotein particles through competition with lipoprotein bound dimeric LPL for the LDL receptor-related protein (LRP receptor) on hepatocytes and macrophages in culture. A decrease of the level of monomeric LPL in plasma may thus be beneficial for remnant catabolism. The same mechanism may on the other hand increase macrophage uptake of lipids. This may not affect global lipid metabolism but may be important in driving the atherosclerotic process in the vessel wall.     

CpG ODN增强乙肝疫苗在老年小鼠中的免疫应答

目的：探讨CpG ODN对老年小鼠的体液和细胞免疫应答的增强作用。方法：选用老年C57BL／6小鼠，将乙肝疫苗和10μg、20μg CpG ODN同时或单独肌注到小鼠体内，两周后以同样剂量加强免疫一次，再过3周后摘除眼球取血，用EILSA方法检测抗HBs16；抗体和IL-12；无菌取脾脏作HE染色，观察脾脏淋巴细胞变化。结果：10μg和20μg CpG ODN与疫苗同时注射组产生的抗体绝对量分别是单独注射疫苗组的3倍和4倍；产生的IL-12水平较对照组有明显升高，且20μg比10μCpG组产生的IL-12水平更高。光镜下各组的脾脏淋巴细胞的变化如下：正常老年鼠组脾脏淋巴细胞较正常青年鼠组明显稀少；老年鼠 10μgCpG组脾脏淋巴细胞较正常老年鼠组有了明显增加，且细胞核也明显增大；20μgCpG组增加的更加明显。结论：CpG ODN能增强乙肝疫苗在老年小鼠中的体液和细胞免疫应答。
