Objective To study the correlation between 5-serotonin transporter ( 5-HTT) gene pol-ymorphism and the first episode major depressive disorder ( MDD ) and cognitive function in adolescent. Methods 5-HTT genotype and allele were detected by polymerase chain reaction ( PCR) amplification of 76 patients with first episode of MDD and 73 normal controls. Case control method was used to analyze the correlation between different genotypes and the onset, the clinical features, and cognitive function. Result-s There was no significant difference between 5-HTTLPR genotype frequencies for the 41 cases of type S/S (53.9%),27 cases of type L/S(35.5%),8 cases of type L/L(10.5%)of case group and 5-HTTLPR geno-type frequencies for the 38 cases of type S/S(52.1%),18 cases of type L/S(24.7%),17 cases of type L/L (23.3%) of control group(P>0.05).Patients with S/S type,L/S type had significantly higher sleep scores than those of patients with type L/L(P=0.005,P=0.001). Agitation score in patients with S/S type group was significantly higher than that in patients with S/L,L/L(P=0.000,P=0.001);patients with S/S inferior-ity scores were significantly lower than those of patients with S/L,L/L(P=0.002,P=0.006). There was no significant difference in cognitive function among three groups. Conclusions In Chinese Han population, there may be no direct association between 5-HTTLPR gene polymorphism and susceptibility to MDD and its cognitive function in adolescents. S/S and L/S patients may be prone to sleep problems,type S/S patients may be prone to irritability and type L/L patients may be prone to inferiority.

OBJECTIVETo investigate the therapeutic effect of facial artery perforator flap for the soft tissue defects at nose, lip and cheek.

METHODSThe facial artery perforator adjacent to the defect was identified by Doppler ultrasonography. The perforator flap was designed according to the defect location, size and shape. The subcutaneous tissue around the perforator was kept as much as possible to protect the venous drainage.

RESULTSFrom Oct. 2012 to Oct.2013, 26 cases were treated with facial artery perforator flaps, with 9 cases of nasal defects, 10 cases of lip defects and 7 cases of buccal defects. The defects size ranged from 1.5 cm x 2.0 cm to 3.0 cm x 3.0 cm and the flaps size ranged from 2.0 cm x 2.5 cm to 3.5 cm x 3. 5 cm. Superficial necrosis(3mm in width) happened at the end of one flap. All the other 25 flaps survived completely. 16 cases were followed up for 3 months to 2 years with no relapse and satisfactory cosmetic and functional results were achieved.

CONCLUSIONSBoth cosmetic and functional effect can be achieved with facial artery perforator flap for defects at nose, lip and cheek.

Objective To investigate the abnormal brain activity of first-episode depression by rest-ing state functional magnetic resonance imaging ( fMRI) .Methods Twenty-one adolescent participants diag-nosed with depression(AD) and 18 healthy controls ( HC) were recruited.Resting state fMRI brain scans were performed on all participants.Regional homogeneity ( ReHo) approach was applied to preprocess the fMRI datasets.The value of ReHo maps were obtained in the whole brain.Results ReHo values in the AD group were higher than those in the healthy controls in the right inferior temporal gyrus ( MINI:66,-24,-20) ,left upper cingulate cortex (-27,47,-6) ,frontal polar (-24,59,14) ,after upper left cingulate cortex (-1,-16,35),after the bottom left cingulate cortex (-2,-38,32),left praecuneus (-1,-48,65) com-pared with that in the healthy controls (P<0.05) .ReHo in the AD group decreased in the right middle tempo-ral gyrus (45,-34,32) compared with that in the healthy controls (P<0.05).Conclusion Extensive ReHo abnormalities were found in the brains of patients with first-episode,drug-naive depression,and these abnor-malities in spontaneous neural activity may contribute to the neuropathology of adolescent depression.

Objective: To investigate the posttraumatic growth and emotional regulation strategies of patients with moderate and severe burns at different time points in the rehabilitation period, and to explore the correlation between posttraumatic growth and emotional regulation strategies, so as to provide a basis for targeted nursing intervention. Methods: By convenience sampling method, 115 convalescent patients with moderate and severe burns in Linyi People′s Hospital burn plastic surgery center were investigated by General Information Questionnaire, Chinese Posttraumatic Growth Inventory (C-PTGI), Emotion Regulation Scale (ERQ) respectively on the day of discharge (T1), 3 months and 6 months after hospital discharge (T2, T3) from December 2017 to January 2019. Results: The post-traumatic growth scores of patients T1, T2 and T3 were 58.18±9.51, 48.65±9.31 and 47.43±8.76, respectively. The post-traumatic growth scores showed a downward trend at three time points, and the difference was statistically significant (F=339.732,P<0.01). The scores of T1, T2 and T3 in the cognitive reassessment dimensions of patients′emotion regulation strategies were respectively 27.10±4.13, 26.95±3.76, 26.11±3.60. The scores are going down and the differences were statistically significant (F=27.798, P<0.01). The expression inhibition scores were 14.42±4.39, 15.20±3.30, 15.21±3.56 respectively. The scores are the rise and the differences were statistically significant (F=13.675, P < 0.01). There were positive correlations between cognitive reassessment scores and posttraumatic growth scores、scores of all dimensions (r=0.230-0.555, P<0.05). The expression inhibition scores were negatively correlated with the total post-traumatic growth scores, personal strength, and scores of new possibility dimensions (r=-0.230--0.420, P<0.05). Conclusion Posttraumatic growth of patients with moderate to severe burns is not optimistic in the rehabilitation period. Therefore, it is necessary to pay attention to the guidance of emotional regulation strategies for patients with moderate to severe burns in the rehabilitation period, and carry out targeted interventions to promote the posttraumatic growth of patients.

Objective:To investigate the characteristics of obesity in adolescents with major depressive disorder (MDD) and its association with the depressed severity.Methods:A total of 278 adolescents with MDD were recruited according to the inclusion and exclusion criteria. Their demographic data were collected and 24-item Hamilton depression scale (HAMD-24) was used to evaluate their severity of depression. According to the body mass index (BMI) classification standard of adolescents in China, all subjects were classified into four groups(wasting group, normal BMI group, overweight group and obesity group). SPSS 26.0 statistical software was used for data analysis. The Kruskal-Wallis test and the Chi-square test were separately used for the comparison of the four groups.Spearman correlation was used to explore the relationship between BMI and HAMD-24 scores and severity.Results:Among 278 adolescents with MDD, the prevalence of body abnormality was 32.4% (90/278), among which wasting, overweight and obesity were 9.0% (25/278), 14.4% (40/278) and 9.0% (25/278) respectively. There were statistically differences in gender ( χ2=17.018, P<0.001), HAMD-24 scores ( H=9.427, P=0.024) and depressed severity( H=8.508, P=0.037) among the four groups. Multiple comparisons showed that there were only statistically differences between obesity group and normal BMI group, that was the prevalence of obesity in males was higher than that in females ( χ2=13.631, P<0.001), and the level in HAMD-24 scores ( Z=2.956, P=0.003) and depressed severity ( Z=2.832, P=0.005) was lower in obesity group than that in normal BMI group.Spearman correlation analysis showed that BMI was negatively correlated with HAMD-24 scores ( r=-0.162, P=0.007). Conclusion:There is gender difference in obesity rates among the adolescent patients with first-episode untreated MDD. And the obese patients are less depressed than those with normal BMI.
