ObjectiveTo investigate the efficacy and safety of sertraline combined with low-dose aripiprazole in the treatment of obsessive-compulsive disorder in children and adolescents. MethodsA total of 62 cases pediatric patients aged 9~16 years who attended the outpatient clinic of a psychiatric hospital in Xiamen from June 2018 to May 2020 and met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for obsessive-compulsive disorder were enrolled in the study. The selected children were randomly classified into two groups for different treatments. Control group （n=30） received sertraline monotherapy， and study group （n=32） received sertraline combined with low-dose aripiprazole treatment. At the baseline and the end of the 2^nd， 4^th， 8^th and 12^th weeks of treatment， children were assessed using Children's Yale-Brown Obsessive Compulsive Scale （CY-BOCS） and Treatment Emergent Symptoms Scale （TESS）. Thereafter， the clinical efficacy and adverse reactions were compared between two groups. ResultsThe compulsive behavior dimensional score of CY-BOCS of study group was lower than that of control group at end of the 2^nd and 4^th weeks of treatment （t=-2.083， -2.176， P<0.05）. At the end of the 2^nd week of treatment， the effective rate was 40.63% in study group， which was significantly higher than 3.33% in control group （χ²=12.317， P<0.01）. By the end of the 12^th weeks of treatment， the incidence rate of side effects yielded no statistical difference between two groups （χ²=1.608， P=0.205）. ConclusionCompared with sertraline monotherapy， its combination with low-dose aripiprazole treatment can effectively accelerate the improvement of clinical symptoms in childrenand adolescents with obsessive-compulsive disorder， while the combination therapy and sertraline monotherapy have equivalent safety.

Objective To analyze the correlation between quantitative evaluation of high-resolution CT (HRCT) and pulmonary function tests (PFT) in chronic obstructive pulmonary disease (COPD), and evaluate the characteristics of PFT in different CT phenotypes of COPD. Methods 65 patients with COPD underwent CT chest scan and PFT. The dimensions of subsubsegmental apical bronchi of right upper lobes were measured , which included the following parameters:airway wall thickness (T), total airway diameter (D), and pulmonary artery (PA), ratio of airway wall thickness and pulmonary artery (T/PA), thickness diameter ratio (TDR), percentage of wall area (WA%) and percentage of airway luminal area (Ai%). The percentage of total lung area occupied by low attenuation area (LAA%) was measured by lung density software. The relationship between the measurements and PFT parameters were analyzed. Patients were classified into three phenotypes based on the presence of emphysema or bronchial wall thickening evaluated by HRCT. Phenotype A: without or with little emphysema (LAA% < 25%), with or without bronchial wall thickening; Phenotype E: emphysema without bronchial wall thickening (LAA%≥25%, T/PA < 30%); Phenotype M: emphysema with bronchial wall thickening (LAA%≥25%, T/PA≥30%). The characteristics of different CT phenotypes were analyzed. Results LAA% had a good correlation with PFT parameters. PA, T/PA, WA% and Ai% also had correlation with PFT parameters. There was 53 patients of Phenotype A, 12 patients of Phenotype M. PA, T/PA, LAA%and PFT were different in two groups. Conclusions LAA%and airway quantitative measurements in HRCT have certain correlation with PFT parameters. Patients with different CT phenotypes differs in PFT parameters , which can provide reference for clinical diagnosis and treatment.

OBJECTIVEBy using orthogonal design method to optimnize prescription of pulsed electric field at Jiaji (EX- B 2) points for spinal cord injury (SCI).

METHODSFifty six patients of SCI were selected, in which 36 cases were divided into orthogonal design trial and 20 cases were into clinical verification. With 36 patients who received orthogonal design trial, Frankel grading scale was used as observation index to screen optimal prescription of pulsed electric field. Pulse frequency (factor A) included low frequency (factor A(I), 10(2) Hz). moderate frequency (factor A(II), 10(4) Hz) and high frequency (factor A(III), 10(3) Hz); pulse amplitude (factor B) included 0-30 V (factor B ), 0-60 V (factor B(II)) and 0-90 V (factor B(III)); pulse width (factor C) included 0.1 ms (factor C(I)). 0.6 ms (factor C(II)) and 0.9 ms (factor C(III)); acupuncture time (factor D) included one month (DI), three months (D(II)) and five months (D(III)). Twenty patients were used for clinical efficacy observation and the effects of screened optimal pre scription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation training on spasm se- verity, score of sensory and motor functions, Barthel index and Frankel score were observed.

RESULTS(1) As results of orthogonal design trial, the optimal prescription was A(III) B(III), C(I), D(III), which were high frequency (10(3) Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. (2) As results of 20 patient clinical verification, Ashworth score, tendon reflex and clonus were all significantly improved (P<0.001, P<0.01), the scores of sensory and motor functions were evidently improvedtl (P<0.001, P<0.05), and Barthel in dex and Frankel score were also enhanced (P<0.001, P<0.05).

CONCLUSIONThe optimal prescription of pulsed electric field at Jiaji (EX-B 2) points for spinal cord injury is high frequency (10& Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. The optimal prescription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation could obviously improve spasm severity, enhance senso- ry and motor functions, and ameliorate activity of daily life and Frankel score.

Objective: To observe the effect of edaravone combining ulinastatin on brain protection in patients of type A aortic dissection (AAD) after total arch replacement. Methods: A total of 60 AAD patients with total arch replacement in our hospital from 2014-09 to 2016-01 were prospectively studied. Based on peri-operative application of edaravone and ulinastatin, the patients were divided into 2 groups: EU group: 1) the patients received ulinastatin 300000 U/8h and edaravone 0.5mg/Kg/12h from administration to 3 days post-operation, 2) during cardiopulmonary bypass, the patients received ulinastatin 300000 U/2h and edaravone 0.5mg/Kg; Control group, the patients had no such treatment.n=30 in each group. The following items were observed:①operative condition;②blood levels of speciifc brain injury markers as S-100 and neuron speciifc enolase (NSE) at different time points: beginning of surgery (T0), opening aorta clamp (T1), right after cardiopulmonary bypass (T2), entering ICU (T3), 24h post-operation (T4) and 3 days post-operation (T5); ③post-operative condition. Results:①Durations of operation, cardiopulmonary bypass, cardiac arrest and bilateral antegrade selective cerebral perfusion (BACP), the frequency of BACP and UACP (unilateral antegrade selective cerebral perfusion), the lowest rectal temperature and blood levels of S-100, NSE at T0 were similar between 2 groups.②Compared with Control group, EU group had decreased S-100 and NSE from T1 to T5,P<0.05.③The in-hospital and ventilation time, frequency of PND and TND, the patients with CSS score≥16 before discharge and the in-hospital death rate were similar between 2 groups,P>0.05. Conclusion: Edaravone combining ulinastatin had brain protective effect in AAD patients after total arch replacement;it may reduce blood speciifc brain injury markers while the clinical signiifcance should be further investigated.

OBJECTIVE: To explore potential application of Diminished Criminal Responsibility Rating Scale (DCRRS) on rape offenders. METHODS: The DCRRS was used retrospectively to study 77 cases of rape offenders. They were divided into three groups according to the degree of diminished criminal responsibility. RESULTS: There were significant differences in rating scores among three groups (mild group 21.32+/-5.56, moderate group 25.92+/-5.19, and major group 29.54+/-4.62), and 16 of 18 items showed good correlation with the total scores of the scale (r=0.256 to 0.611), 7 factors were extracted by the factor analysis and their cumulative squared loadings was 75.784%. CONCLUSION The DCRRS is valid and reliable in a in assessment of criminal responsibility schizophrenic rape offenders.
