RésuméParmi les facteurs favorisant les conduites addictives, certaines caractéristiques du fonctionnement familial sont souvent évoquées dans les troubles alimentaires et dans les dépendances aux substances psychoactives ou à lalcool. La mise à lépreuve des observations des processus familiaux par des recherches empiriques intégrant différents niveaux épistémologiques et méthodologiques a conduit à des résultats contradictoires concernant les différentes formes de fonctionnements familiaux associés à ces pathologies addictives. Cet article propose une revue critique de la littérature dans le cadre des conceptions systémiques concernant les dérèglements familiaux impliqués dans lapparition des troubles alimentaires et des dépendances aux substances ou à lalcool chez les adolescents. Il sagira également de discuter la similarité des caractéristiques familiales entre ces pathologies addictives et lhypothèse dune typologie familiale propre aux conduites addictives.AbstractAmong factors favoring the addictive behaviors, some specific family processes are often identified in eating disorders and dependences with psychoactive substances. Different models of systemic orientation described the familial disturbances involved in the addictive pathologies emphasizing either the emotional interaction and the processes of differentiation family, either the structure and the level of family cohesion. This article proposes a critical review of the systemic literature on the familial disturbances involved in the families of adolescents with eating disorders or with a substance-dependence. The systemic models (Bowen, Minuchin) are reference values in the understanding of family processes and therapy with families. The observations of these family processes have been confronted to empirical researches integrating different epistemological levels and different methods. The empirical results are heterogenous concerning the different forms of family functioning associated with these addictive pathologies. The empirical studies support the hypothesis of a family dysfunctioning in the different addictive behaviors and demonstrate the relationship between the severity of familial disorders and the severity of the addictive disorders. However, the family configuration described by the typological models is rarely found complete or with a similar intensity between the families. The studies support the hypothesis of an emotional distance in the family interactions and a lack of parental care which could correspond to factors of chronicity or vulnerability. Comparing the family characteristics of these two types of addictive behaviors, the literature supports the existence of (1) some specific family characteristics according to the type of addictive behavior (in particular the conflict avoidance which appears specifically in anorexic families) (2) some similar family patterns of interactions between the members of addictive families in particular the representation of a low family cohesion, an intergenerational enmeschment and a high level of control. These family patterns suggest rather to a dimensional approach of the family characterized by different protective or risk factors. We suggest that these family patterns could constitute, according to their importance (intensity and frequence), a family risk factor of development or aggravation of the addictive behaviors.Mots clés: Addiction; Troubles alimentaires; Dépendances aux substances; Adolescence; FamilleKeywords: Addiction; Eating disorders; Drug dependence; Adolescence; FamilyArticle Outline12.2.1. 2.2. 33.1. 3.1.1. 3.1.2. 3.1.3. 3.1.4. 3.2. 3.2.1. 3.2.2. 3.2.3. 3.2.4. 3.2.5. 3.2.6. 4.

AbstractBackgroundAlthough incidence of schizophrenia is higher among cannabis users and marijuana is the most common abused drug by adolescents, etiological linkage between schizophrenia and cannabis use is still not clarified. Clinical experiences suggest that regular cannabis user can show similar psychotic episode to schizophrenic disorders but it is still unclear if chronic cannabis use with schizophreniform disorder is a distinct entity requiring special therapy or it can be treated as classical schizophrenia. There are no data available on the comparison of pharmacotherapy between schizophreniform patients with and without cannabis use.MethodsClinical data of 85 patients with schizophrenia spectrum disorder were analyzed retrospectively. Cannabis use was not reported by 43 persons (Cnbs0 subgroup) and 42 patients used regularly cannabis during at least 1 year (Cnbs1 subgroup). Comparison of anamnesis, family history, social-demographic condition, positive and negative symptoms, acute and long-term therapies recorded by clinical interviews was performed with chi square tests, logistic binary regression and t-tests using SPSS 13.0 for Windows software.ResultsMen were over-represented in cannabis dependent group while mean age was lower among them compared to Cnbs0 subgroup. Prevalence of suicidal attempt was increased in men without cannabis use (OR = 5.25, p = 0.016). Patients without cannabis use spent more time in hospital (p = 0.026) and smoking was more frequent among them (OR = 1.36, p = 0.047). The chance to get olanzapine for acute therapy and aripiprazol for long term therapy was more than two fold in Cnbs1 subgroup (OR = 2.66, OR = 3.67, respectively). However, aripiprazol was used for acute therapy with significantly lower risk in Cnbs1 subgroup (OR = 0.47, p = 0.023). Olanzapine was administered for long term therapy in a higher dose to Cnbs0 patients (p = 0.040). Also higher dose of risperidon LAI was used in women without cannabis dependency compared to women of Cnbs1 subgroup (p = 0.020). Positive and negative symptoms and family history did not differ significantly between the two subgroups.ConclusionAlthough symptom profile was similar, hospitalization time, suicidal anamnesis, smoking habit and also dosage, intensity and lasting of therapy were different between the two subgroups. Further prospective studies are required for the investigation of the clinical and molecular background of this discrepancy in order to determine a relevant protocol of prevention and treatment of the chronic cannabis use related psychotic disorder.Research HighlightsThis is the first complex clinical comparison including pharmacotherapy between schizophrenia with and without cannabis use. We found that although symptom profile was similar, hospitalization time, suicidal anamnesis, smoking habit and also dosage, intensity and lasting of therapy were different between the two subgroups. Our data suggest that besides shared components, vulnerability for cannabis use and schizophrenia and maybe also for addictive disorders may have different pathogenetic factors, consequently altered molecular background and alternative pharmacological response.Keywords: Addiction; Cannabis; Psychosis; Psychopharmacotherapy; THCAbbreviations: CB1, cannabinoid receptor 1; CGI-S, Clinical Global Impression Scale; CGI-I, Clinical Global Improvement Scale; Cnbs, cannabis; HPDC, haloperidol decanoate; LAI, long acting injections; OR, odds ratioArticle Outline12345.· 2、利用EI 数据库“快速检索”检索铝合金表面激光溶覆研究，关键词：铝合金（Aluminum alloy）；激光溶覆（laser cladding），限定：在“主题/题名/摘要”字段中进行检索；时间是2000年以来发表的文章。要求：列出你的检索表达式和检索步骤，列出2-3篇文摘式检索结果。检索表达式和检索步骤: 进入安徽工业大学图书馆网页，点击EI 数据库,进入页面。检索表达式：Aluminum alloy and laser cladding, January 2011, Pages 49-53  | Copyright © 2010 Elsevier Ltd All rights reserved.   Microstructure characteristics of Ti3Al/TiC ceramic layer deposited by laser cladding Li Jianing, Chen Chuanzhong, , and Zong Leia Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials (Ministry of Education), Department of Materials Science, Shandong University, Jinan , PR ChinaReceived 18 April 2010;  accepted 8 July 2010.  Available online 15 July 2010. AbstractAl + TiC laser cladding coatings were prepared on Ti6Al4V alloy by CO2 laser cladding technique. The microstructure, micro-hardness and phase constitutes of the laser cladding layer were investigated by means of scanning electron microscope (SEM), X-ray diffraction (XRD) and microsclermeter. The results indicated that the laser cladding layer solidified into the fine microstructure rapidly, and TiC hard phase was dispersived in the cladding layer. When the mass percent of TiC was 40%, the micro-hardness (1100HV0.21250HV0.2) of Al + TiC cladding layer was 3 times more than that of the Ti6Al4V alloy substrate (350370HV0.2). The cladding layer mainly consisted of -Ti (Al), -Al (Ti), Ti3Al, TiAl, Al3Ti and TiC phase. There phases were beneficial to improve the hardness and wear resistance of the cladding layer.Keywords: Titanium alloy; Laser cladding; Surface modification; Microstructure; Phase constituteArticle Outline122.1. 2.2. 33.1. 3.2. 3.3. 4, 15 October 2009, Pages 2392-2397  | Copyright © 2009 Elsevier B.V.

The physicochemical properties of the nanoparticles were characterized by various techniques, and uniform nanoparticles with an average particle size of 116 ± 15 nm with high encapsulation efficiencies (EE) were obtained. Additionally, a sustained release of paclitaxel from paclitaxel-loaded chitosan nanoparticles was successful. Using different ratios of paclitaxel-to-chitosan, the EE ranged from 32.2 ± 8.21% to 94.0 ± 16.73 %. The drug release rates of paclitaxel from the nanoparticles were approximately, 26.55 ± 2.11% and 93.44 ± 10.96% after 1 day and 13 days, respectively, suggesting the potential of the chitosan nanoparticles as a sustained drug delivery system. Cytotoxicity tests showed that the paclitaxel-loaded chitosan had higher cell toxicity than the individual paclitaxel and confocal microscopy analysis confirmed excellent cellular uptake efficiency. TEM images showed the ultrastructure changes of A2780 cells incubated with paclitaxel-loaded nanoparticles. Flow cytometric analysis revealed two subdiploid peaks for the cells in the paclitaxel-loaded nanoparticles and paclitaxel treated groups, respectively, with the intensity of the former higher than that of the latter. Moreover, the cell cycle was arrested in the G2-M phase, which was consistent with the action mechanism of the direct administration of paclitaxel. These results indicate that chitosan nanoparticles have potential uses as anticancer drug carriers and also have an enhanced anticancer effect.Keywords: Chitosan; Nanoparticles; Paclitaxel; Sustained release; Ovarian cancerArticle Outline122.1. 2.2. 2.3. 2.4. 2.5. 2.6. 2.7. 2.8. 2.9. 2.10. .33.1. 3.2. 3.3. 3.4. 3.5. 3.6. 3.7. 4专心-专注-专业
