The enhanced expression of the matrix metalloproteinase 9 in nasal NK/T-cell lymphoma

Background  

Nasal NK/T cell lymphoma is an aggressive disease and has a poor prognosis. Nasal NK/T cell lymphoma is refractory to conventional chemotherapy and has strong tendency of widespread relapse or dissemination into distant sites.     

Longitudinal,population-based study of racial/ethnic differences in colorectal cancer survival: impact of neighborhood socioeconomic status,treatment and comorbidity

Background  

Colorectal cancer, if detected early, has greater than 90% 5-year survival. However, survival has been shown to vary across racial/ethnic groups in the United States, despite the availability of early detection methods.     

Panhypopituitarism as first manifestation of a lung cancer

Pituitary metastases of solid tumours are infrequent, specially as a first manifestation. When they happen, they are usually due to breast or lung cancer and are asymptomatic or produce diabetes insipidus. It is very strange that they produce hormonal deficiency. We present a case report of a bronchogenic adenocarcinoma in a 65-year-old man which began with panhypopituitarism, diabetes insipidus and visual alterations. Magnetic resonance imaging revealed a large sellar mass, with clivus infiltration and invading the right cavernous sinus. The biopsy result was adenocarcinoma metastases from lung cancer.     

论太阳伤寒与"非典"

通过比较，发现仲景所论之太阳伤寒与传染性非典型肺炎二者之间在病因、病机、发病、传变等方面存在诸多一致或相似，因此根据辨证论治的精神，提出二者治疗可以互通，并针对传染性非典型肺炎在早期、进展期、恢复期的不同症状表现，分别指出了《伤寒杂病论》中宜投用的经方。     

Cathodes for fuel cells using proton-conducting Li2SO4–Al2O3 electrolyte

The performances of three widely different cathode materials (Pt, strontium-doped lanthanum manganite (LSM), and NiO) have been compared for use with proton conducting Li₂SO₄–Al₂O₃ composite electrolyte, using H₂S–air and H₂–air fuel cells operating at 600 °C. Surface analysis and electrochemical techniques were used to characterize fresh and used electrode materials. Pt or LSM cathodes each became covered with Li₂SO₄ and Al₂O₃ and, as a consequence, the fuel cells showed poor performance. In contrast, the NiO cathode catalyst did not become covered with Li₂SO₄ and good fuel cell performance was achieved. Exceptionally good current densities of over 100 mA/cm² and power densities of over 30 mW/cm² were obtained for H₂S–air fuel cells having Mo–Ni–S anode catalysts. Slight agglomeration of NiO particles during fuel cell operation had only a minor effect on performance.     

高血压家系802人的高血压患病率、知晓率、治疗和控制状况调查

目的了解高血压家系人群高血压患病率、治疗率和控制率特点。方法用整群随机抽样调查的方法调查高血压家系高血压的流行和控制情况，分析比较相关指标的差异。结果家系成员高血压患病率为55．86％，存在危险因素聚集现象。高血压的知晓率、治疗率、控制率分别为79．46％、62．72％、19．64％。结论该地区高血压家系高血压患病率较高，遗传因素是重要原因。虽高血压控制水平较高，但需加强高血压的一级预防。     

新型加速器放疗网络的研制及其临床应用

目的研制新型加速器放疗网络。方法采用服务器-客户端模式．服务器采用SQL—Server2000为数据库服务软件，客户端使用VC＋＋6．0语言编写．通过RTP—Link以及DICOMRT和新型加速器连接传输病人治疗参数资料。结果成功研锚的新型加速器放疗网络包括病人资料管理模块、定位计划管理模块、定位图像预处理模块、靶区勾画模块、计划设计管理模块（包含MLC（多叶光栅）设计以及低熔点挡铅设计）和治疗参数输出（包括报表打印、连接加速器）。结论网络系统操作简单，适合新型全数字化加速器的常规放射治疗管理．是科室常规放疗治疗的质量保证（QA）和质量控制（QC）的有效工具。     

Do cancer patients fully understand clinical trial participation? A pilot study to assess informed consent and patient expectations

Background. Accepted practices of informed consent often result in suboptimal patient understanding of research studies.Methods. This pilot study aimed to assess trial-specific tailored materials, compared to a widely used generic booklet about clinical trials, randomly assigned to 118 candidates for cancer clinical trials. Study outcomes were: satisfaction with decision-making; satisfaction with materials; and subjective understanding of the clinical trial.Results. There were no major differences between groups. Participants rated tailored materials higher as a useful reference.Conclusions. Trial-specific materials hold utility for reference during clinical trials. Studies of informed consent are feasible, although important factors limit research.     

胆囊炎和胆石症的饮食疗法

胆囊炎、胆石症的发病及复发与饮食密切相关。中医素有“药食同源”之说,《内经》曾有“虚则补之,药以祛之,食以随之”和“谷肉果菜,食养尽之等饮食疗法的论述。饮食疗法简称食疗,首先应遵循食疗原则,主要是注重辨证施食,并辅以药膳。食疗原则胆囊炎、胆石症的食疗目的是注意饮食习惯避免诱发疼痛发作(即胆绞痛),并保证胆囊收缩正常,使胆汁排泄通畅,去除引起胆汁淤滞的因素,抑制胆石的生成。其食疗的基本原则是:1饮食规律忌暴饮暴食。2控制脂肪摄入,适量摄取蛋白质3材料要新鲜,烹调要柔软,口味要清淡。4少吃辛辣品,禁饮酒。5多吃蔬菜、水果,…
