肺心病血液光量子治疗前后血液流变性质变化及机制探讨

１５例肺心病血液高粘滞患者自体血２５０ｍｌ用ＸＺＹ－Ⅰ型量子血液治疗机进行紫外线照射和充以纯氧后再输入，每周一次，最多连续做三次（平均１．８６±０．７１次）后，作者发现血液全血高切、低切粘度，全血高切、低切还原粘度，血浆比粘度，血浆纤维否白原含量，红细胞聚集指数，红细胞电泳率等有显著性改变，单纯常规治疗组１５例患者血液流变无此变化，分析认为，这些变化可能与红细胞聚集性降低、纤维蛋白源溶解度提高及血氧饱和度增加有关。     

Abnormal sensorimotor integration is related to disease severity in Parkinson's disease: a TMS study.

Hyperexcitability of the motor system has been reported in Parkinson's disease (PD). We evaluate how cutaneous afferents modulate motor excitability in PD patients and whether abnormal modulation is correlated to parkinsonian symptoms. Digital stimulation causes abnormal enhancement of motor responses in patients. This effect may be one of the features of motor hyperexcitability in PD. Cutaneomotor hyperexcitability correlates with clinical scores, suggesting that abnormal processing of cutaneous inputs might contribute to the pathogenesis of parkinsonian symptoms.     

Primary hydatid cyst of the breast: A case report

We describe herein the rare case of a hydatid cyst found in the breast of a 26-year-old woman. Clinically, the mass was at first suspected of being a fibroadenoma, but fine needle aspiration cytology (FNAC) yielded clear fluid only. Histopathologic examination of the resected speciman confirmed that it was a hydatid cyst.     

A cross-reactive idiotype in scleroderma

Autoantibodies to centromere proteins (anti-CENPs) and to topoisomerase-I are highly specific for scleroderma. Unlike most autoantibodies in other diseases, these autoantibodies are mutually exclusive. We have analysed the idiotypes (Ids) expressed by anti-CENP-B, antitopoisomerase-I, and IgGs from 20 scleroderma patients. Rabbit anti-Ids were prepared to antitopoisomerase-I from two scleroderma patients, and to anti-CENP-B from four patients. These six anti-Ids were used to study the purified autoantibodies from 20 scleroderma patients: four antitopoisomerase-I, 10 anti-CENP-B, and six purified IgG from scleroderma patients who were negative for both autoantibodies. In addition, we studied sera from 40 normal autoantibody-negative controls, and sera and purified immunoglobulins from 17 systemic lupus erythematosus (SLE) patients containing high titres of anti-double-stranded DNA, and/or autoantibodies to extractable nuclear antigens (ENA). Using direct binding, and competitive inhibition ELISAs and immunoblots, we identified an Id present in the heavy chains of all the affinity-purified antitopoisomerase-I, and anti-CENP-B. Interestingly, this Id was also present in the immunoglobulins of the scleroderma patients who had neither of the two autoantibodies. By contrast, cross-reactive Id-EM was not found in the sera or immunoglobulins from 17 SLE patients, or in the sera from 40 normal subjects. Several samples from two patients showed that this cross-reactive Id-EM was stable over time. The scleroderma disease-specific autoantibodies may be identified through a common structural feature at the variable region of the heavy chain: cross-reactive Id-EM.     

1994～2001年广西疾病监测点甲、乙类传染病发病特点分析

目的 通过对广西疾病监测点1994—2001年甲、乙类传染病发病特点进行分析，为广西甲、乙类传染病的防治提供科学的依据和建议。方法 运用Epi Info2000统计软件将监测点1994～2001年甲、乙类传染病报告资料进行整理分析。结果 监测点的报告发病率高于常规疫情，甲、乙类传染病总体发病水平呈下降趋势，农村地区所报病种远多于城市；肠道传染病呈逐年下降，血源及性传播疾病呈上升趋势，肺结核已成为广西高发病种。结论 广西疾病监测工作的建设仍需加强，肠道传染病防治工作不能放松，呼吸道传染病和血源及性传播疾病的控制力度要加强。     

Recombinant human erythropoietin in the treatment of cancer-related anaemia

Abstract: The efficacy and safety of recombinant human erythropoietin (rhEPO) were tested when given subcutaneously (s.c.) in an escalating dose of 2000–10,000 units (U) daily in 60 patients with cancer-related anaemia (CRA). A positive response, defined as an increase in haemoglobin more than 2 g/dl and independence of blood transfusions, was observed in 23 of 48 evaluable patients (48%) within a median of 8 wk. In detail, rhEPO corrected anaemia in 11 of 14 patients (79%) with malignant lymphoma, in 8 of 15 patients (53%) with multiple myeloma and in 4 of 10 patients (40%) with a solid tumour. The median dose of rhEPO in successful cases was 5000 U daily. Four patients with agnogenic myeloid metaplasia and 5 with myelodysplastic disorder failed to respond to rhEPO. No patient had any severe side effects. Pretreatment serum erythropoietin levels appeared to be a weak predictor for response to rhEPO treatment. In conclusion, rhEPO seems to be safe and effective in correcting CRA in certain groups of patients.     

Left-sided superior vena cava: diagnosis by magnetic resonance imaging

We describe a case of left-sided superior vena cava. The diagnosis was suggested by chest radiograph after central venous catheter placement. This was subsequently confirmed by magnetic resonance imaging. Received: 4 March 1997 Accepted: 21 March 1997     

慢性HBV感染患者HBsAg亚型分析

对包括慢性肝炎、肝炎肝硬变和原发性肝癌在内的１００例慢性ＨＢＶ感染者作了ＨＢｓＡｇ亚型分析。结果显示，在这组病例中ａｄｒ亚型占６１％，ａｄｗ占３３％，ａｙｒ占２％，ａｄｗｒ占４％。ａｄｒ亚型有随年龄增长更占优势的趋向。ａｄｒ和ａｄｗｒ亚型感染者ＨＢｓＡｇ滴度较ａｄｗ组显著增高，且ｅ抗原阳性率亦较高。上述发现提示，具有ａｄｒ和ａｄｗｒ亚型的ＨＢＶ株可能具有较强的复制活性，不易被清除，从而导致受感染者     

汉族、哈萨克族Graves病患者血清CoL IV、LN和HA测定分析

用放免法(单克隆抗体)测定汉、哈萨克族Graves病未经治疗患者66例及正常对照组55例血清中Ⅳ型胶原(CoLⅣ)、板层素(IN)和透明质酸(HA),结果Graves病患者血清CoLⅣ、LN浓度明显升高,HA浓度明显降低,与正常对照组相比均有显著性差异(分别P<0.001、P<0.05、P<0.05),汉族与哈萨克族患者之间、对照组之间相比均无显著性差异(P>0.05),它反映了Graves病患者体内基底膜合成和分解代谢紊乱。
