胰腺癌细胞的增殖同膜脂质饱和度,膜胰岛素受体的关系

外源性表皮生长因子(或生长抑素)能促进(或抑制)胰腺癌细胞的增殖。胰腺癌细胞增殖速率的高低与细胞膜脂质饱和度的降、升;与膜胰岛素受体数量的增减密切相关。测定细胞膜脂质饱和度和胰岛素受体数量,是判断胰腺癌增殖状态的灵敏指标,有一定临床价值。     

Subclinical hepatic encephalopathy: relationship between neuropsychological deficits and standard laboratory tests assessing hepatic status.

A multivariate analysis of the relationship between biochemical measures of hepatic function and neuropsychological assessments of specific cognitive domains was performed on data obtained from 74 patients with chronic liver disease and subclinical hepatic encephalopathy. Biochemical tests of hepatic protein synthesis correlated significantly with measures of impaired language efficiency, perceptual speed, and psychomotor efficiency. Biochemical indices of impaired processing of nitrogenous compounds correlated with visuopractic deficits. Hepatic blood flow indices correlated with language inefficiency. Interestingly, biochemical measures of hepatic injury did not demonstrate a significant association with any neuropsychological parameter assessed. These results suggest that subclinical hepatic encephalopathy is the consequence of a multifactorial hepatic dysfunction, and that acute hepatic injury, as assessed by elevation of aminotransferases, does not appear to be involved in the pathogenesis of subclinical hepatic encephalopathy.

低强度超短波对小鼠体质及智力的影响

本实验探讨了低强度超短波对小鼠连续三代辐射,对学习、记忆、拉力、运动耐力和周围血象的影响。用81MHz,10～12V/m 的超短波进行辐射,每天辐射2小时,每周6天。结果表明:经过超短波辐射的各代小鼠与对照组相比,学习能力、记忆能力、拉力及运动耐力有明显的降低,且运动耐力有进行性降低的趋势,而经过辐射的三代小鼠红细胞、血红蛋白含量及白细胞数均明显增高,每个红细胞的血红蛋白含量则低于对照组。

Newer antiviral agents and therapeutic approaches for chronic hepatitis b

A new era in the treatment of chronic hepatitis B began approximately a decade ago. Three oral nucleoside or nucleotide analogues—lamivudine, adefovir dipivoxil, and entecavir—are now approved in the United States for the treatment of chronic hepatitis B. Other new oral agents, including telbivudine, clevudine, and emtricitabine, are in various stages of clinical investigation. This article reviews the efficacy and resistance data of these oral antiviral agents, and the preliminary results of combination therapy for chronic hepatitis B.     

颅脑损伤所致人格改变的量化评估

目的:通过对颅脑损伤所致器质性人格改变的患者进行量化评估分析,以寻找一种最适合颅脑损伤后人格改变的量化评估方法。方法:全部病例来自2003-01-03/2005-01-31期间到深圳市康宁医院法医精神病司法鉴定所进行工伤鉴定的工伤所致颅脑损伤患者116例,所有病例首先由综合医院神经外科行头颅CT或MRI检查,并对颅脑损伤的部位、性质、严重程度等做出诊断和治疗。治疗终结后,由两名副高级主任医师及以上职称的精神医学鉴定专家对患者的精神状况进行评估,并分别做出有无人格改变的诊断。同时采用慢性脑器质性人格改变评定量表(包括10个条目)及自编脑外伤后人格改变评定量表(包括5个因子17个条目)对患者人格改变的情况进行量化评定。以专家诊断结果为效标,对两种量表对颅脑损伤所致人格改变的判定灵敏度和特异性以及两量表的内部条目进行分析。结果:①颅脑损伤所致人格改变专家评定及量表评定结果:经专家鉴定,116例颅脑损伤患者中诊断为颅脑损伤所致器质性人格改变的患者22例,占所有调查对象的19%,评估者的诊断一致性kappa值为0.86(P<0.01)。以专家诊断为效标,慢性脑器质性人格改变评定量表对本组颅脑损伤患者所致人格改变诊断的假阳性率为0,假阴性率为50%;自编脑外伤后人格改变评定量表的假阳性率为2.4%,假阴性率为4.5%。②两种量表评定颅脑损伤所致人格改变的内部条目分析:慢性脑器质性人格改变评定量表各条目评分结果显示有人格改变与无人格改变的患者在情绪不稳、情感淡漠或不协调、社会功能减退、个性改变、行为障碍5个条目的差异显著(t=2.082～5.921,P<0.01～0.05)。自编脑外伤后人格改变评定量表除认知偏离因子中的所有条目外,情感偏离因子中的情绪不稳,情感脆弱,易激惹,情感平淡、不关心人4个条目,意志行为偏离中的意志缺乏,欲望增强,行为冲动、不计后果,自我中心4个条目,人际关系偏离及原有人格变化及其所有条目上均有显著性差异(t=13.339～2.094,P<0.01～0.05)。结论:自编脑外伤后人格改变评定量表提高了对颅脑损伤所致人格改变诊断的灵敏度,其各条目能更准确地反映颅脑损伤所致人格改变的临床特点,但其信度和效度还需进一步完善。     

肺螨病的病理观察

本文报道螨类接种豚鼠气管引起的肺部病变,并对5种常见螨类的致病性进行比较。发现螨类接种后6天豚鼠肺部已形成典型的结节性病灶。结节圆锥形淡黄色,直径1～5mm之间。镜下表现为细支气管炎和细支气管周围炎,肺实质内有明显的异物肉芽肿形成,炎症在螨类接种豚鼠20天时,肺部嗜酸粒细胞浸润不明显,但30或40天时则出现明显的嗜酸细胞浸润,细支气管周围小动脉受到损害,部分小动脉内可见到螨体残骸。5种常见螨炎接种于5组豚鼠可引起大致相同的病变。从而证明豚鼠可作为动物模型以供肺螨病的研究,同时也证明5种常见贮藏螨具有相同的致病性。     

Failure of intensive chemotherapy in poor prognosis non-Hodgkin's lymphoma

In an attempt to improve response and survival rates in patients with non-Hodgkin's lymphoma, a relatively intense six drug regimen MATCOP was developed comprising four-weekly cycles of methotrexate (100mg/m², IV_Y day 8), Adriamycin (30mg/m², IV_Y days 1,2), teniposide (75 mg/rn², IV, day 1), cyclophophamide (300 mg/m², po, days one to five), Oncovin (1.4 mg/m², IV: maximum 2 mg, days 8,15) and prednisolone (100 mg, po, days one to five). A randomised trial was conducted comparing MATCOP with the standard CHOP regimen, comprising three-weekly cycles of cyclophosphamide (750 mg/m², IV, day 1), Adriamycin (50 mg/m², IV, day 1), Oncovin (1.4 mg/m² IV: maximum 2 mg, day 1) and prednisolone (100 mg, PO, days two to six). Eighty patients with large cell lymphoma, diffuse mixed small cleaved and large cell lymphoma or diffuse small cleaved cell lymphoma were randomised, 47 to MATCOP and 33 to CHOP. MATCOP patients experienced increased granulocytopenia, thrombocytopenia (p 0.0001), mucositis (p= 0.002) and infections (p= 0.01) compared to CHOP patients. Complete response rates were similar: 66% for MATCOP patients and 61% for CHOP patients. There were no apparent differences in the time to relapse for patients achieving CR, the time to treatment failure or the overall survival time. Thus despite an increase in toxicity, the more intense regimen MATCOP failed to confer any therapeutic benefit compared with the standard CHOP regimen. Survival was not influenced but toxicity was increased by dose intensification. (Aust NZ J Med 1992; 22: 123–128.)
