Objective To evaluate the clinical efficacy of monosegmental pedicle instrumentation in management of thoracolumbar burst fractures. Methods A total of 67 patients with traumatic thora-columbar burst fractures (type A3.1 and A3.2) were treated with monosegmental pedicle instrumentation in our department from October 2003 to February 2008. Imageologic effect was observed by measuring sagittal index and wedge index via X-ray and clinical outcomes evaluated by using low back outcome score. Results All operations were performed successfully, with average operation duration of 93 mi-nutes and average intraoperative blood loss of 157 ml. Of all, 65 patients were followed up for 4-27 months (average 19.8 months), which showed that all the patients achieved bony fusion, with no implant failure except for one with screw loosening. The sagittal index and wedge index were 13.06°and 42.9% preoperatively and 4.47° and 21.78% postoperatively, with statistical difference (P <0.01). The final follow-up showed no significant correction loss except for two patients (P < 0.05). The low back outcome scores of all patients at follow-up were improved significantly (P < 0.05). Conclusions Monoseg-mental pedicle instrumentation has advantages of minimal invasion, short operative duration, less blood loss and less vertebral motion segment loss and hence is an effective and reliable operative technique for thoracolumbar burst fractures.

Objective To evaluate cognitive impairment and performance-based skills and to explore their rela?tionships with clinical phenotypes in drug-na?ve first-episode patients with schizophrenia. Methods One hundred and forty-five inpatients and 65 healthy controls matched for age, gender and education were recruited. The MATRICS Con?sensus Cognitive Battery (MCCB), Stroop, digit span test, emotional recognition test, University of California, San Diego, Performance-based Skill Assessment (UPSA) and Positive Negative Syndrome Scale scale (PANSS) were used to evaluate cognitive function, life skill and symptoms, respectively. Results Compared with the controls, total score of MCCB and scores of 10 subscales, scores of digit span, emotional recognition and Stroop were significantly lower in patients (all P<0.05). The UPSA total score and scores of financial skill and communication skill were lower in patients than in controls (all P<0.05). Verbal memory, visual memory , Stroop, communication skill scores and total UPSA standard score were sig?nificantly higher in patients with paranoid subtype of schizophrenia than in patients with non-paranoid subtype of schizo? phrenia (all P<0.05). The score of MCCB associated with education years (OR=1.29, 95%CI: 1.13~1.47) and PANSS (OR=0.95, 95%CI:0.92~0.97). Conclusions First-episode, drug-naive patients with schizophrenia have markedly cog?nitive and performance-based skills deficits, which are associated with clinical symptoms. These deficits are differences between paranoid subtype and non-paranoid subtype of schizophrenia.

Objective:To explore the effect of attentional bias training on the attentional bias, psychological craving and relapse rate of alcohol dependent patients during rehabilitation.Methods:A randomized controlled trial was used to select 90 alcohol-dependent patients and randomly divide them into an intervention group and a control group. The alcohol cue pictures and neutral pictures were imported into E-Prime software at a ratio of 1∶1.The patients in the two groups were trained for eight times with attentional bias and without attentional bias by point delection paradigm. After each training, the software automatically records the response time and correct rate of the cue pictures and neutral pictures, and before intervention(T0), after 4 interventions(T4), and after 8 interventions(T8), the alcohol craving score was assessed by visual analogue scale and the relapse situation was followed up 1 month after the intervention. SPSS 24.0 software was used for statistical analysis.Repeat measure ANOVA, χ2 test and t-test were used to compare the response time, accuracy and psychological craving of the two groups. Results:Repeated measurement analysis of variance showed that there were interaction between group and time in cue-map response time, line chart accuracy and psychological craving score of the two groups ( F=5.218, 6.939, 147.14, all P<0.01). Simple effect analysis showed that there was no significant difference in cue pictures response time, cue pictures accuracy and psychological craving score between the intervention group and the control group at T0(all P>0.05), but there was significant difference at T4 and T8 (all P<0.05), and there was significant difference in neutral pictures reaction only at T8 ( P<0.05). The comparison between two groups showed that the intervention group showed a downward trend in cue pictures response, T4 and T8 were lower than T0, with statistical difference (both P<0.001), while there was no difference in the control group. In the intervention group, the correct rate of cue pictures increased, T4 and T8 were higher than T0, and there were statistical differences (both P<0.001), while there was no difference in the control group( P>0.05). The psychological craving scores of both the intervention group and the control group showed a downward trend, T4 and T8 were lower than T0, there were statistical differences (both P<0.001), but the difference between T4 and T8 in the control group remained unchanged. One month after the end of the intervention, the difference in the rate of relapse between the intervention group and the control group was marginal (11.10%, 26.70%, P=0.059). The total number of days of abstinence in the intervention group was longer than that in the control group ((28.33±4.99)d, (26.47±6.66)d, P=0.010). Conclusion:Attentional bias training can improve the mental craving and attentional bias of alcohol-dependent patients during the rehabilitation period, and the relapse rate decreased one month after the intervention.
