Objective To explore the resting state cortical activity and frontal asymmetry in alpha oscillations in bipolar depressive patients and its relationship with clinical symptoms. Methods Twelve bipolar depressive patients (pa?tient group) and twenty-four well-matched healthy volunteer (control group) were underwent whole head MEG recording. Individual spectral power and frontal asymmetry index were calculated by using permutation test to discover the differenc?es in δ, θ, α1, α2, α3, β bands between the two groups among the regions of interested (bilateral central, frontal lobe, temporal lobe, parietal lobe, occipital lobe). The correlation analysis were used to analyze the association between power of brain regions with significant difference and the Hamilton depression rating scale17 scores as well as factor items in patients. Results Compared with the control group, the activity of various regions was increased in the patient group as follows:theδband in the left central and left occipital lobes, theθband in the left occipital lobe, theβband in left cen?tral, right frontal, left parietal lobe and right parietal lobe. The power ofα2 andα3 frequency bands was decreased in the bilateral temporal lobes (P<0.05, uncorrected). A negative correlation was observed between the right temporalα3 power and recognition item scores for bipolar depression (P<0.05). Conclusion The present study suggests that bipolar depres?sive patients have impaired neural activity at many bands and the symptom of cognitive impairment may be associated with dysfunction ofα3 band.

Objective:
To explore the safety and feasibility of transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments in treatment of cryptorchidism in children.
Methods:
Thirty-five children with cryptorchidism were treated by transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments from November 2017 to March 2018 at Department of Pediatric Surgery, the First Affiliated Hospital of Guangxi Medical University.Clinical data were recorded including the general information, operation time, intraoperative blood loss, postoperative testicular position and postoperative complications, etc.
Results:
All 35 patients completed the cryptorchidopexy in one operation.Among those 35 patients, 28 patients had unilateral lesions and 7 patients had bilateral lesions, with a total of 42 sides.Twenty-six patients were of groin type(33 sides), 9 patients abdominal type(9 sides). The average operation time was (40.4±8.2) min for unilateral lesion, and (62.5±15.3) min for bilateral lesions; the average intraoperative blood loss was (3.0±1.8) mL; and the average postoperative hospital stay was (6.4±2.1) h. Testis of 32 patients (40 sides) were fixed in the middle and bottoms of the scrotum, and testis of 2 patients (2 sides) were fixed on the top of the scrotum.One case had poor healing of naval incision, which was recovered in 1 week after dressing change.There were no postoperative complications such as scrotum hematoma, infection of incision, testicular epididymitis, testicular necrosis, testicular retraction or testicular atrophy, etc.No obvious visible scar was found in the abdomen review 2 weeks postoperatively, with the incidence of complications was 2.9%(1/35 cases).
Conclusions
Transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments in treatment of cryptorchidism is characterized by small trauma, quick recovery, low complication rate and visible scar free result, which is worthy of clinical promotion, but the operation is relatively complex and the correct procedures are required.

Objective:To explore the difference of gray matter volume between anxious depression(AD)and non anxious depression(NAD) patients, and its correlation with clinical characteristics.Methods:One hundred and fifty patients with depression were included from September 2014 to October 2018, meanwhile 62 healthy controls with matching demographic characteristic were recruited. The severity of the patients was assessed by Hamilton depression scale-17(HAMD-17). Patients were divided into anxious depression group(AD group, n=80)and non-anxious depression group (NAD group, n=70) according to whether anxiety/somatization factor scored 7. All subjects were scanned with 3.0 T underwent structural MRI scan. The structural magnetic resonance data were preprocessed by voxel-based morphometry (VBM). The rest toolkit was used to calculate the difference of gray matter volume among the three groups. By SPSS 19.0, post-hoc t test was used for pairwise comparison and Pearson correlation analysis was performed between gray matter volume and clinical factors in patients with anxious depression. Results:Compared to the NAD group, the gray matter volume of the right middle frontal gyrus(MNI: x=28.5, y=21.0, z=48.0, t=-4.83, Bonferroni multiple comparison adjustment, P<0.05/3) and left dorsolateral superior frontal gyrus(MNI: x=-18.0, y=27.0, z=43.5, t=-6.08, Bonferroni multiple comparison correction, P<0.05/3)were significantly decreased in AD group. Correlation analysis found that the gray matter volume of the right middle frontal gyrus in patients with anxious depression was negatively correlated with the insight of anxiety/somatization factor score ( r=-0.36, P=0.001). Conclusion:The volume of prefrontal lobe in patients with anxiety depression is lower than that in patients with non anxiety depression, which may be related to the serious clinical symptoms in patients with anxiety depression.The decrease of right middle frontal gyrus volume can be used as a potential biological marker for the severity of impaired insight.
