The aim of the present study was to examine the relapse time and analyse the social, psychological and physical factors related to relapse among drugdependent patients who had undergone neurosurgery by ablating the nucleus accumbens (NAc surgical group) and those who had undergone detoxification with non-operative treatment in residential compulsory rehabilitation centres (control group). A total of 100 patients from the NAc surgical group and 92 patients from the control group were recruited in the study for 5 years. Information regarding their experiences of previous abstinence from drug use and the relapse time was obtained by interviews, while the relapse reasons were obtained through questionnaire. The study shows that there is a significant correlation in relapse reasons between the two groups. 'Relief from disturbance' (psychological factor) and 'peer influence' (social factor) were the two main factors associated with relapse. Factors like 'desire for last use' and 'boredom' (psychological factor) were more associated with relapse in the control group than the NAc surgical group. At 5 years post-operation, the number of patients in the employment and married status in non-relapse group was significantly higher than in the relapse group. There was also a statistical difference in the 5-year survival rate between them. The average relapse time was the first three years. Thus prevention of relapse to drug dependence after detoxification, especially for those with NAc surgery should be improved to focus on the main factors and time.Keywords

This study was designed to analyse the soil bacterial community composition and diversity, as well as their relationships with various environmental factors in a riparian ecosystem. The 16S rRNA sequencing technology was applied to profile the bacterial composition of 120 samples from four different transects (long, moderate, less and rare inundation) in ten different study sites along the Lijiang riparian zone; the corresponding soil properties were also measured. The results indicated that, diversity was lowest in the rare inundation transect and there were high yet not significantly different bacterial community diversities in the long, moderate, and less inundation transects. The dominant bacterial groups of the four transects were similar, but there were great differences in the abundances of specific groups. Proteobacteria (29.28%), with the dominant classes of Beta- (15.65%), Delta- (5.75%), Gamma- (4.46%) and Alpha-proteobacteria (3.32%), was the most abundant phylum in the studied riparian soils. The genus Candidatus Nitrososphaera including ammonia-oxidizing archaea (AOA) and the genus Nitrospira including nitrite-oxidizing bacteria were both sensitive to inundation gradient changes. Redundancy analysis revealed that soil properties such as soil pH, inundation frequency, sand content, soil water content, total N and available N were significantly correlated with the bacterial community diversity and structure. The study suggests that the flood disturbance gradient and the spatial heterogeneity of soil properties affect the composition and diversity of bacterial communities in the Lijiang riparian zone.Keywords
