头孢噻肟在恶性血液病合并感染患者体内杀菌效价及临床疗效比较

目的 对比观察头孢噻肟（ＣＴＸ）与其他两种抗菌药物治疗方案对３０例血液病合并感染患者杀 菌活性（ＳＢＡ）及临床疗效。方法ＳＢＡ采用微量稀释法测定，临床疗效根据临床治疗登记表按三 级标准判定。结果与结论 头孢噻肟的临床反应最佳，杀菌作用时间维持较长，但对绿脓假单胞 菌和阴沟肠杆菌杀菌作用较差；呱拉西林（ＰＩＰ）与阿米卡星（ＡＮ）方案的抗菌谱广，但ＰＩＰ杀菌 作用时间较短，可考虑缩短给药间期，而ＡＮ可按一日一次给全日量的方案，以提高疗效减少不 良反应；头孢哌酮（ＣＰＺ）可主要用于绿脓假单胞菌感染，也可用于其它细菌的混合感染，但给药 间隔时间以一日三次为宜。     

Isolation of isoguanosine fromCroton tiglium and its antitumor activity

This paper describes the isolation of isoguanosine from Croton tiglium L. and its cytotoxic effect against several tumor cell lines in culture and newly reports that isoguanosine has an antitumor activity against implanted S-180 ascitic tumor mice. Isoguanosine is effective at the dose of 24 mg/kg/day x 5, with T/C value of 168%. Isoguanosine inhibits the growth of S-180 and Ehrlich solid tumor in mice at the optimal doses of 96 mg/kg/day x 12 and 48 mg/kg/day x 12, with 1-T/C values of 65% and 60%, respectively.

山莨菪碱防治甘油所致急性肾功能衰竭的实验研究

在１２９只ＳＤ大鼠的实验中动态观察了山莨菪碱对甘油所致急性肾功能衰竭时不同时期的Ｂｃｒ，ＢＵＮ，ｐＨ病理改变及死亡率的影响，结果表明：山莨菪碱能降低ＡＲＦ第５天大鼠死亡率以及Ｂｃｒ，ＢＵＮ水平。改善病理损害，对ＡＲＦ起到预防及治疗效果，山莨菪碱的预防效果优于治疗效果，预防是ＡＲＦ防治的关键，但山莨菪碱在治疗过程中要引起“冲刷综合征”导致洗脱性酸中毒，应引起注意。

Carotid intima-media thickness in Parkinson's disease.

There have been a few studies and inconsistent results regarding the coincidence of Parkinson's disease (PD) and atherosclerotic diseases, such as cerebrovascular disease. Carotid intima-media thickness (IMT) is a known marker for subclinical atherosclerosis. The aim of this study was to investigate the carotid IMT between PD patients and controls. We studied 43 patients with PD and 86 matched controls. The carotid IMT in PD patients was significantly smaller than in controls (0.796 +/- 0.179 mm vs. 0.913 +/- 0.237 mm, P < 0.05). In multivariate analysis, the carotid IMT was inversely associated with the duration of levodopa medication and the severity of PD. These results suggest that PD patients have a lower risk of atherosclerosis.     

Paired kidney analysis of tacrolimus and cyclosporine microemulsion-based therapy in Chinese cadaveric renal transplant recipients

Few studies used paired kidneys for comparison between tacrolimus and cyclosporine in renal transplantation. Most of the published data used whole blood trough levels for drug monitoring. However, the use of limited sampling strategy and abbreviated formula to estimate the 12-h area under concentration-time curve (AUC(0-12)) allowed better prediction of drug exposure. Sixty-six first cadaveric renal transplant recipients receiving paired kidneys were randomized to receive either tacrolimus-based (n = 33) or cyclosporine microemulsion (Neoral)-based therapies (n = 33). Abbreviated AUC(0-12) was used for drug monitoring and dose titration. Mean follow-up duration was 2.8 +/- 2 years. The patient and graft survival were comparable. Fewer incidence of acute rejection was observed in tacrolimus group (15% vs. 27.3%) though the difference was not significant (P = 0.23). The absolute value and the rate of decline of creatinine clearance were both significantly better in tacrolimus-treated patients. Prevalence of hypertension, post-transplant diabetes mellitus, infection, and malignancy were similar in both groups. Prevalence of hypercholesterolemia (11/33 vs. 4/33) and gum hypertrophy (6/33 vs. 1/33) was more common in cyclosporine-treated patients (P = 0.04 in both parameters). This was the first prospective, randomized study with paired kidney analysis showing the renal function was significantly better in tacrolimus-treated patients than in cyclosporine-treated patients.     

Factors Affecting Cardiac Catheterization Rates in Elders with Acute Coronary Syndromes

Background: Elder patients with acute coronary syndromes (ACS) are less likely to receive cardiac catheterization. The reasons for this are unclear.
Objectives: To assess whether elder patients who had a documented history of dementia, lived in extended care facilities, or had do not intubate–do not resuscitate (DNR-DNI) advance directives were less likely to receive cardiac catheterization, despite having ACS with high-risk features.
Methods: This was a medical record review conducted at an urban teaching hospital. DNR-DNI status before hospitalization, extended care facility (nursing home or assisted living) residence, and a previous diagnosis of dementia were obtained from the medical record. Patients 65 years and older who presented to the emergency department with acute myocardial infarction or with unstable angina with ST segment deviation were included. Univariate and multivariate logistic regression were performed, and odds ratios (ORs) were reported with their 95% confidence intervals (CIs).
Results: Of the 201 eligible patients, 66 (32.8%) patients did not undergo cardiac catheterization. In the univariate analysis, patients who had dementia, resided in extended care facilities, or were DNR-DNI were less likely to receive cardiac catheterization. Only extended care facility residence (OR, 0.18; 95% CI = 0.04 to 0.83) and DNR-DNI status (OR, 0.19; 95% CI = 0.04 to 0.92) remained significantly associated with decreased cardiac catheterization in the multivariate analysis.
Conclusions: Elder patients with ACS residing in extended care facilities or who are DNR-DNI are less likely to receive cardiac catheterization. Future studies concerning the quality of ACS care for elders should take these variables into account.     

重视神经康复的教学问题

随着老年人口比例的不断增大,脑血管病的发病率很难下降,卒中的一个显著特点是致残率高,继发障碍如肌萎缩、关节挛缩、足下垂、足内翻、肩关节半脱位等的根本原因是患肢的长期制动,幸存者不同程度地丧失劳动能力,早期康复训练可以大大降低其程度.而有些神经系统疾病,如遗传性疾病,甚至完全依赖于神经康复的治疗和护理.为提高患者的生活质量,康复治疗的重要性已为越来越多的人所认识.
