Objective To explore the effect of repetitive transcranial magnetic stimulation(rTMS)on the sleep disorder and examination results of recruits.Methods At a training base,the Pittsburgh Sleep Quality Index(PSQI)was used to screen the recruits with sleep disorders(total score of PSQI>7).The recruits were randomly assigned to rTMS group or sham rTMS group.Both groups received cognitive and behavioral intervention therapy,including sleep health education and relaxation training.Moreover,the rTMS group was treated with rTMS at the right posterior parietal lobe by continuous theta burst stimulation(cTBS)twice a day at an interval of at least 50 min for 5 consecutive days as a course of treatment with an interval of 2 days for a total of 2 courses of treatment.The coil position and stimulus intensity of sham rTMS group were consistent with the rTMS group,but the head of subjects was perpendicular to the coil plane and there was no effective stimulation.Before and after treatment,PSQI,self-rating depression scale,generalized anxiety disorder-7 and health questionnaire-15 were used to evaluate the sleep,mood and physical state of the recruits.The training result was assessed one month after treatment.The total effective rate of PSQI improvement and examination results were compared between the two groups.The independent influencing factors of excellent examination result were analyzed.Results Among 351 recruits,83 with sleep disorders completed treatment and follow-up.There were 40 patients in the rTMS group and 43 patients in the sham rTMS group.There was no significant difference between the two groups at baseline.After treatment,the total effective rate of PSQI improvement in the rTMS group was higher than that in the sham rTMS group(77.50%vs 53.49%,P=0.022).The average examination score and excellent rate of the rTMS group were higher than those of the sham rTMS group(91.58±3.19 vs 89.47±4.67,P=0.020;85%vs 65.12%,P=0.037).Logistic regression analysis showed that the treatment mode(rTMS group)was the independent influencing factor of excellent examination results(P=0.032).Conclusion rTMS can effectively and safely improve the sleep disorders and examination results of recruits.rTMS may play a positive role in improving the learning and training effect of recruits,which needs to be further proved.

Anhedonia is one of the core symptoms of major depressive disorder, and its underlying mechanisms remain unclear. The regulation of the reward process in brain regions, such as the hippocampus, amygdala, striatum, ventral tegmental brain, and prefrontal lobe, may play a role in anhedonia. This study has concluded the changes in relevant brain regions in reward anticipation, decision-making, and feedback processes. The neuroimaging mechanisms of inflammation, neurotransmitter metabolism, and gene expression on depression anhedonia symptoms were reviewed.

Half of adult patients with obsessive-compulsive disorder (OCD) report the onset of OCD symptoms during their childhood or adolescence. Early intervention can effectively reduce the prevalence of OCD in the adults. Cognitive-behavioral therapy (CBT) is one of the most effective psychotherapy approaches when treating pediatric OCD. However, the neurobiological mechanism remains unclear. In recent years, the rapid development of brain imaging technic provides an important method to explore the brain mechanism of CBT treatment. Therefore, this article reviews the latest brain imaging research on the treatment mechanism of CBT in pediatric OCD, in order to provide a robust evidence for the application of CBT in the treatment of pediatric OCD.

Objective:To explore the risk factors for nonunion or malunion after internal fixation of femoral neck fracture.Methods:A retrospective analysis was done of the 140 patients with femoral neck fracture who had been admitted to Department of Traumatology and Orthopedics, Weifang People's Hospital from January 2013 through June 2019. They were 61 males and 79 females, aged from 18 to 65 years (average, 51.3 years). All patients received "inverted triangle" internal fixation with 3 hollow nails after reduction. The univariate analysis was conducted of the 9 factors: age, gender, fracture side, Garden classification, injury-to-operation time, reduction quality, postoperative ambulation with crutches but no weight-bearing, preoperative bone density, and preoperative 25-hydroxyvitamin D3 concentration. Multivariate logistic regression analysis was used for the factors with P<0.05 to identify risk factors. P<0.05 was considered statistically significant. Results:This cohort of 140 patients obtained follow-up for 6 to 12 months (average, 10.8 months). Nonunion or malunion occurred in 25 cases of them (17.86%). The multivariate logistic regression analysis showed that Garden types Ⅲ&Ⅳ ( OR=2.873, 95% CI: 1.027~8.039, P=0.044), non-anatomic reduction ( OR=4.678, 95% CI: 1.133~19.310, P=0.033), postoperative ambulation time with crutches but no weight-bearing <3 months ( OR=0.230, 95% CI: 0.072~0.737, P=0.013), and preoperative 25-hydroxyvitamin D3 concentration<30 ng/mL ( OR=3.718, 95% CI: 1.337~10.341, P=0.012) were the risk factors for nonunion or malunion after internal fixation of femoral neck fracture. Conclusion:The risk factors for nonunion or malunion after internal fixation of femoral neck fracture may be the Garden types Ⅲ&Ⅳ, non-anatomic reduction, postoperative ambulation time with crutches but no weight-bearing <3 months, and preoperative 25-hydroxyvitamin D3 concentration < 30 ng/mL.

Objective:To compare the changes of cerebral blood flow (CBF) in bipolar disorder type Ⅱ patients with and without suicidal ideation.Methods:Pseudo-continuous arterial spin labelling (pCASL) was examined with resting-state functional magnetic resonance imaging(rs-fMRI) on all subjects, CBF images of bipolar disorder type Ⅱ depression with suicidal ideation ( n=48), Bipolar Disorder type Ⅱ without suicidal ideation ( n=41), healthy controls ( n=62) at rest were collected. One-way ANOVA and Gaussian random field (GRF) were used to compare the CBF values between the groups to locate the regions with significant change. Results:Compared with the control group, CBF of left superior temporal gyrus (extending to the temporal pole) ( t=3.87, P<0.01; t=4.44, P<0.01) and left putamen ( t=4.04, P<0.01; t=3.19, P<0.01) increased in bipolar disorder type Ⅱ patients with and without suicidal ideation, and CBF of the right posterior cingulate gyrus (extending to the calcarine gyrus) decreased in bipolar disorder type Ⅱ patients with suicidal ideation( t=-4.66, P<0.01). Conclusions:There were abnormal CBF in left superior temporal gyrus and left putamen in bipolar disorder type Ⅱ patients with suicidal ideation and bipolar disorder type Ⅱ patients without suicidal ideation, while the decreased CBF in right posterior cingulate gyrus may be the specific brain change in bipolar disorder type Ⅱ patients with suicidal ideation.

Ultrasound-based measurement of relative blood volume can be used to assess patient's dry weight during hemodialysis. The results of relative blood volume were calculated from the ultrasonic transmission time measurement in the arteriol pot, and the accuracy of transmission time measurement is directly related to the reliability of the results of relative blood volume. There are various factors which influence the travel time, this article analyzed patients themselves, measuring device and the external factors, and advised appropriate counter measures.

OBJECTIVE: To evaluate the safety and effect of foley catheter traction for hemorrhage after postmicrochannel percutaneous nephrolithotomy (mPCNL). METHODS: Eighty-eight patients with upper urinary calculi were collected prospectively at the Department of Urology of Xiangya Hospital of Central South University from November 2010 to June 2011. The patients underwent mPCNL, and were divided into 2 groups randomly: 45 patients with 16F foley catheter but without traction served as the control group, and the other 43 patients with 16F foley catheter traction served as the experiment group. Blood loss was estimated by the mass of hemoglobin in the draining liquid and urine during postoperative duration through the HiCN. The blood loss and bleeding time were compared in the 2 groups, and analyzed by Wilcoxon rank sum test. RESULTS: There was statistical difference in the average blood loss between the control group (13.830 g) and the experiment group (7.959 g, P<0 .001). The mean bleeding time was 4 and 3 days in the control group and the experiment group respectively. CONCLUSION Foley catheter traction for mPCNL can reduce the blood loss, suggesting that Foley catheter traction is safe, effective and feasible.
