Improvement of Decreased Critical Flicker Frequency (CFF) in Headache Patients With Drug Abuse After Successful Withdrawal

A considerable proportion of headache patients fulfill the criteria of "drug abuse" (definition according to the International Headache Society [IHS] criteria). These patients exhibit markedly reduced vigilance and continuous performance, as shown by the results of critical flicker frequency (CFF) analysis.
The present study deals with the question whether this impairment of vigilance and continuous performance is reversible. Forty-eight headache patients with drug abuse were investigated three times by means of CFF analysis: immediately before (A), immediately after (B), and 3 weeks after having finished (C) inpatient drug withdrawal.
Immediately after withdrawal, a significant decrease of headache intensity was observed. The CFF values, however, remained unchanged at a depressed level, probably due to withdrawal medication and the initial sedative side effects of thymoleptic agents (given as prophylaxis).
Three weeks after withdrawal, however, the CFF values were significantly improved, and were now within a range not far from the normal values known from a healthy general population. Thus, even after many years of drug abuse, headache patients have a good chance to improve their vigilance and continuous performance and to reach normal or close to normal levels.

Investigation of Direct Causes of Drug Relapse and Abstainers’ Demands in a Compulsive Detoxification Center in Wuhan City of China

Objective To identify the direct causes of drug relapse and abstainers’ demand, and to develop programs for the prevention of drug relapse. Methods Abstainers in a Compulsive Detoxification Center in Wuhan City, capital of Hubei Province were randomly selected. An investigation on the direct causes of drug relapse and abstainers’ demands was conducted with multiple-choice questionnaires and face to face interviews. Data were analyzed with SPSS 12.0. Results The direct causes leading to drug relapse included: temptation to use drug again by themselves or by their drug mates, seeking pleasure and ecstasy from drug use, relatively well off living, mental stress, irritation, demoralization, family conflicts, unemployment, feeling distrusted by the family, lack of care and love from the family, and discrimination by others. abstainers’ demands after detoxification and returning to the society included: care and support from the family, employment assistance, changing living environment, understanding by others, support from the society, and keeping far away from drugs. Conclusions Environmental factors are the direct causes of drug relapse, and negative irritation is its predisposing causes. Leaving former residence, more care and help given by both the family and the society and raising their overall quality of life are the demands of abstainers.     

Hospital outbreak caused by a carbapenem-resistant strain of Acinetobacter baumannii: patient prognosis and risk-factors for colonisation and infection

Between October 2001 and August 2002, 30 hospital patients became infected or colonised by a multiresistant (including to carbapenems) epidemic strain of Acinetobacter baumannii (AbMR) in a hospital outbreak. This study analysed the risk-factors associated with acquisition of this epidemic strain and investigated the prognosis of patients infected by AbMR, with the aim of elucidating factors which lead to mortality. A case-control study of the acquisition of AbMR in patients infected or colonised in the hospital outbreak was performed. Independent risk-factors leading to death were studied by logistic regression analysis. Multivariate analysis of the risk-factors for colonisation/infection with AbMR revealed an independent association with the presence of an arterial catheter (OR, 1.13; 95% CI, 1.03-1.25) and administration of imipenem as monotherapy (OR, 11.12; 95% CI, 2.33-53.09). Multivariate analysis of the prognostic features leading to mortality revealed a significant association with hypotension or shock (OR, 24.63; 95% CI, 1.56-387.56) at the time of bacterial isolation.

人肝癌裸鼠移植模型阿霉素诱导法建立肝癌多药耐药细胞系

目的:建立人肝癌多药耐药细胞系研究其耐药特性及机制.方法:给予移植人肝癌细胞的裸小鼠腹腔注射阿霉素(ADM)长期诱导,获得多药耐药细胞系BEL-7402/ADM.相差显微镜和HE染色观察细胞,MTT法检测耐药细胞的多药耐药性,流式细胞术检测耐药细胞表面多药耐药基因(mdr)的表达产物P糖蛋白(P-gp)、多药耐药相关蛋白(MRP)及谷胱甘肽硫转移系统(GSH/GST)的表达.结果:BEL-7402/ADM对多种抗癌药物产生耐药,对阿霉素的耐药性提高了20.33倍.BEL-7402/ADM细胞表面P-gp和MRP表达阳性,与对照细胞BEL-7402表达比较,差异十分显著(P<0.01).GSH/GST表达无明显变化.结论:BEL-7402/ADM具有明确的多药耐药性,该模型的建立对研究肝癌多药耐药的产生及逆转具有重要价值.
