固定剂量复合剂治疗肺结核患者依从性调查与分析

Objective To survey and analyse the treatment compliance of fixed-dose combination （FDC）,so as to provide evidences for expending use FDC nationwide. Methods Nine hundred and sixty-six primary smear positive pulmonary tuberculosis cases registered in 17 counties TB institutions from 4 provinces were randomly divid- ed into experiment and control groups. Compared compliance difference with uniform questionnaires, and analysed compliance changes with time throughout the treatment. Results Nine hundred and sixty-one cases were surveyed at the beginning, 899（93.5% ）preferred receiving treatment. There was significant difference on the percentage who prefer had drugs per day between experiment（86.8% ）and control group（42.1% ）（ P 〈 0.01 ）.At the end of intensive phase, 261（28.3 % ）cases perceived difficulty with the treatment ;213 （23.1% ）cases thought that were the doctors who lead to the insist of treatment.At the end of treatment,only 138 cases（15.5% ）thought that were the doctom who lead to the insist of treatment. Conclusion The compliance of FDC was better than control group. It might increase the compliance when decreasing the number of tablets and should expend used on TB control. The ef- fect of TB doctors decreased through the treatment. More intention should be paid in intense phase.     

运用市场手段实现医药自然分开的理论探讨

回顾了韩国、我国台湾和大陆实行医药分开改革的过程,认为我国以往的相关改革陷入了“管制”的思维误区。认为通过制度设计,创造医疗机构门诊处方自由流动的环境,依靠市场竞争形成处方流向结构多元化,可以实现医药自然分开状态。提出了“医药自然分开”、“处方流向结构”和“处方分散度”等新概念。

Intravenous drug abuse and Type 1 diabetes: financial and healthcare implications.

AIMS: To determine the morbidity, mortality and healthcare costs of intravenous drug-abusing patients with Type 1 diabetes (IVDA-DM), who are admitted to hospital. METHODS: Retrospective case note analysis of admissions, complications and cost estimation over a 6-year period. Each drug-abusing patient (IVDA-DM) (n = 9) was compared with two controls (n = 18) with Type 1 diabetes but without a history of intravenous drug abuse (DM-controls). Admissions were also analysed for patients with intravenous drug abuse, but without Type 1 diabetes (IVDA-controls) (n = 198). Admissions were at a University teaching hospital in Liverpool, UK. DM-controls were drawn from a population attending diabetes outpatient clinics between 1997 and 2002 at the same hospital. The main outcome measures were: the duration and healthcare costs of hospital admissions per year, outpatient attendances per year, glycated haemoglobin (HbA(1c)), weight, micro- and macrovascular complications and mortality. RESULTS: Multiple admissions, mainly related to ketoacidosis, led to marked differences in mean (95% CI) inpatient days per year per patient [IVDA-DM 28.1 (13.6-42.7) vs. DM-control 1.1 (0.2-1.9); P < 0.0001], mean inpatient days per year per patient in critical care bed (IVDA-DM 1.7 (-0.7-4.2) vs. DM-control 0; P < 0.02) and mean costs of admission, per patient per year (pound sterling 7320 vs. pound sterling 230). The IVDA-DM group frequently omitted insulin, were underweight, failed to attend as outpatients and five had died by the end of 2002. The IVDA-controls spent considerably less time in hospital [3.4 (2.8-3.9) days per patient per year]. CONCLUSION: IVDA-DM patients have higher rates of diabetes complications, are admitted more frequently and have a high mortality compared with DM and IVDA-controls. The cost of inpatient care of this small group of patients was considerable.     

Inhibition of angiogenesis by antibody blocking the action of proangiogenic high-molecular-weight kininogen

Summary.  Previously we demonstrated that domain 5 (D5) of high-molecular-weight kininogen (HK) inhibits neovascularization in the chicken chorioallantoic membrane (CAM) assay and further found that kallikrein cleaved HK (HKa) inhibited FGF2-and VEGF-induced neovascularization, and thus was antiangiogenic. In this study, we sought to demonstrate whether uncleaved HK stimulates neovascularization and thus is proangiogenic. The chick chorioallantoic membrane was used as an in ovo assay of angiogenesis. Low-molecular-weight kininogen stimulates angiogenesis, indicating that D5 is not involved. Bradykinin stimulates neovascularization equally to HK and LK and is likely to be responsible for the effect of HK. A murine monoclonal antibody to HK (C11C1) also recognizes a similar component in chicken plasma as detected by surface plasmon resonance. Angiogenesis induced by FGF2 and VEGF is inhibited by this monoclonal antibody and is a more potent inhibitor of neovascularization induced by VEGF than an integrin α_vβ₃ antibody (LM 609). Our postulate that C11C1 inhibits the stimulation of angiogenesis by HK was confirmed when either C11C1 or D5 completely inhibited angiogenesis in the CAM induced by HK. Growth of human fibrosarcoma (HT-1080) on the CAM was inhibited by GST-D5 and C11C1. These results indicate HK is proangiogenic probably by releasing bradykinin and that a monoclonal antibody directed to HK could serve as an antiangiogenic agent with a potential for inhibiting tumor angiogenesis and other angiogenesis-mediated disorders.
