乙型肝炎甲胎蛋白检测与重型肝炎预后指数评估的意义

给慢性活动肝炎患者输注人胎肝细胞悬液引起血清甲胎蛋白增高反应的初浓度为２０２±３８．３μｇ／Ｌ，其半衰期为１．７天；分布池为６．９一１０．２升。重型肝炎生存组血清甲胎蛋白显著高于死亡组，生存组甲胎蛋白与血清总胆红素呈非常显著相关，而死亡组两者无相关性。重型肝炎患者输注胎肝悬液后其血清甲胎蛋白进一步升高者，预后较好。取重型肝炎预后指数０．１为重型肝炎生死的截断点，判断预后的灵敏度、特异度、准确度和阳性预告值分别为７９．５％、８９．６％、８４．８％和８７．５％。重型肝炎预后指数的计算可作为判断预后与新疗法疗效的指标。

Effects of a Broad-spectrum Behavioral Medicine Treatment Program on Children with Refractory Epileptic Seizures: An 8-Year Follow-Up

We present an 8 year follow-up on a group of children with refractory epileptic seizures who participated in the early 1980s in a controlled group study on the effects of a broad-spectrum behavior modification treatment program on children with refractory epileptic seizures. In the original study, 18 children were divided into three groups: behavior modification group, attention control group, and control group. The purpose was to investigate the effects of a learning-based treatment program superimposed on a regular medical treatment program. Also, the effects of professional attention were evaluated. At the 10 week and 1 year follow-ups, only the group receiving the behavior modification intervention had a significantly reduced rate of seizure index. The present study investigates these same children 8 years later using the same methods of investigation for an additional 10 week period. The results indicate that a significant reduction in seizures was obtained only for the behavior modification group at the 8 year follow-up.     

胃癌腹腔脱落细胞检查及临床意义

腹膜转移是胃癌常见的转移形式。为在肉眼可见转移前发现亚临床的转移现象,自1981年3月至1982年4月,我们共对胃癌病人142例进行了腹腔脱落细胞检查及临床随诊,发现有腹腔脱落细胞阳性者76例(53.5％)。5年随诊结果发现,腹腔脱落细胞阳性者无一例生存>3年;而腹腔脱落细胞阴性的66例中生存5年者有11例。可见,腹腔脱落细胞检查,对胃癌的诊断,治疗和预后判断有一定价值。     

Phenotypic and genetic analyses of T-cell-mediated immunoregulation in patients with Type 1 diabetes.

AIMS: To investigate the contribution of regulatory T cells and co-stimulatory molecules in CD4(+) T cells to the development of Type 1 diabetes (T1D). METHODS: Twelve patients with T1D, nine patients with systemic lupus erythematosus (SLE), and 12 age-matched healthy control subjects participated. We analysed the proportions of CD25(+)CD4(+) T cells and natural killer T cells (NKT cells), and the expression levels of Foxp3, CTLA-4, CD28, ICOS, PD-1 and BTLA in peripheral blood mononuclear cells and purified CD4(+) T cells. RESULTS: There were no significant differences in the proportions of CD25(+) CD4(+) T cells or NKT cells among the three groups. PD-1 expression levels of peripheral CD4(+) T cells from T1D patients were significantly lower than those from healthy control subjects (P = 0.00066). In contrast, PD-1 expression levels were similar in SLE patients and healthy control subjects. The expression levels of Foxp3, CTLA-4, CD28, ICOS and BTLA were similar in the three groups. CONCLUSIONS: Decreased expression of the PD-1 gene in CD4(+) T cells may contribute to the development and/or maintenance of autoimmune T1D. As the population studied was small and heterogeneous, further studies are required to confirm the findings.     

微血管密度测定在子宫内膜癌病变发展中的价值

目的　探讨血管生成活性在子宫内膜癌发展中的价值。方法　采用Ⅷ因子相关抗原为标志物 ,以免疫组化技术对正常子宫内膜、不典型增生内膜 ,子宫内膜癌组织进行微血管密度 (MVD)测定。结果　①正常组与内膜癌组比较 (P <0 .0 1) ,正常组与不典型增生组比较 (P <0 .0 5 ) ;从正常内膜、不典型增生到内膜癌组织内MVD逐渐增多 (P <0 .0 5 )。②内膜癌组织内MVD与肿瘤细胞分化程度有关 (P <0 .0 5 )。结论　临床采用MVD测定对子宫内膜增生病变发展和追随检查具有重要价值 ,同时MVD测定可作为判断子宫内膜癌预后的指标之一。

Factors associated with recovery and recurrence of depression in older people: A prospective study

The Liverpool Continuing Health in the Community Study has followed up 1070 elderly community subjects over 6 years. In the first year 123 subjects had case-level depression. Three years later 49 (39.8%) of the previously depressed were recovered, 33 (26.8%) were depressed, 16 (13%) were not available for interview and 25 (20.3%) were dead. This study looks at factors associated with the 3-year outcome of patients who were depressed at year 0. Two outcome groups that were compared were a recovered depression group and a recurrent/persistent depression group. The factors that were significantly associated with a recurrence of depression (or persistent depression) at year 3 were bereavement of a close figure in the 6 months before interview, loneliness and life dissatisfaction at year 3. A variety of traditional risk factors for depression (including age, marital status, physical ill-health and incapacity) failed to attain significance in predicting recurrent or persistent depression. When combined, both recovered and recurrently depressed groups at year 3 had significantly higher levels of pain and a higher number of serious upsets in the past 6 months and 6 weeks compared to a compared to a control group. The depressed at year 0 were more likely to have entered more dependent forms of accommodation by year 3.     

Monospecific but not polyreactive human hybridoma rheumatoid factors exhibit preferential binding specificities for IgG3 and IgG4

Summary Among 38 human hybridoma-derived monoclonal rheumatoid factors (RFs) generated from patients with either rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE), two groups of RFs can be identified. Monospecific RFs were derived primarily from patients with RA and are characterized by a binding specificity for IgG3 and/or IgG4. Polyreactive RFs were derived largely from patients with SLE and show a broader pattern of reactivity to all four isotypes of IgG. Neither population of RFs was exclusive to either disease. The binding specificities identified appear to be different from the RFs isolated from patients with mixed cryoglobulinemia and may reflect a different antigen selection mechanism.     

Effects of Nephritis No.3 Recipe on Nitric Oxide,Nitric Oxide Synthase Secreted by Cultured Mesangial Cells in Rats and the Gene Expression of Inducible Nitric Oxide Synthase

Objective:To explore the effect of the Nephritis No.3(N-3)recipe on nitric oxide(NO),nitric oxide synthase(NOS)secreted by cultured mesangial cells(MC)and its gene expression of the in-ducible nitric oxide synthase(iNOS).Methods:The drug(nephritis No.3)-containing serum was preparedwith serum pharmacological technique,and then was applied to react on mesangial cells cultured In fetalcalf serum(FCS)and cells cultured in FCS plus lipopolysaccharide.To observe the secretion of NO andNOS and the gene expression of iNOS by means of RT-PCR.Results:Under the two kinds of culture con-ditions,the content of NO and NOS in the groups with drug-containing serum were higher than thosewithout drug-containing serum(P<0.05,P<0.01),and the expression of iNOS mRNA was up-regula-ted too.Conclusion:The N-3 could significantly promote the secretion of NO and NOS and the mRNA ex-pression of iNOS in rats.
