Objective To compare the effects on neurobiological factors of attributional retraining group therapy (ARGT) or selective serotonin reuptake inhibitors (SSRI) for major depressive disorder (MDD),anxiety disorder (AD) and obsessive-compulsive disorder (OCD).Methods Outpatients with MDD,AD and OCD were divided into ARGT group (n =63) and SSRI group (n =66) according to the sequence of entering the study.MDD,AD and OCD patients were respectively measured with Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after 8 weeks treatment.All subjects were detected of plasma serotonin,norepinephrine,cortisol and adrenocorticotropic hormone by radioimmunoassay before and after treatment.Results After treatment,HAMD scores of MDD patients were reduced significantly in both ARGT group (t =18.411,P =0.000) and SSRI group (t =20.092,P =0.000) ; HAMA scores of GAD patients were reduced significantly in both ARGT group (t =13.989,P=0.000) and SSRI group (t=15.815,P=0.000) ;Y-BOCS scores of OCD patients were reduced significantly in both ARGT group (t =5.465,P =0.000)and SSRI group (t =4.792,P =0.000).In ARGT group,MDD (t =3.145,P =0.006),AD (t =2.785,P =0.012) and OCD patients (t =2.877,P =0.011) decreased plasma cortisol concentrations significantly.In SSRI group,MDD (t =-2.923,P =0.010) and OCD patients (t =-2.301,P =0.035) improved plasma serotonin significantly and MDD patients (t =-2.333,P =0.033) improved plasma norepinephrine significantly.Conclusion ARGT can modulate plasma cortisol level.SSRI can up-modulate plasma serotonin level.The two therapies take effect by different biological ways.

ObjectiveTo explore the diagnostic value of 16-slices CT in urinary calculus. Methods25 cases of suspected urinary calculus were examined by 16-slices CT and some of these images were reconstructed with MPR. ResultsIn the 25 casces CT found 21cases of urinary calculus,among them kidney calculus 22 cases,urinary tract calculus 13 cases.In 5 of 21 cases,urinary calculus were not found with US.In all 6 cases urinary calculus were not detected by KUB and/or IVP. Conclusion16-slices CT was a valuable method in diagnosing urinary calculus.

OBJECTIVE: To investigate the level of H2-Ab1 in the nasal mucosa of mice with allergic rhinitis. METHOD: Twenty-four female 129/sv mice were divided into 2 groups: ovalbumin (OVA) group and control. The allergic rhinitis models were induced by classical method with OVA. After the last challenge, the pathological differences between the two groups were surveyed. The levels of H2-AB1 were measured by ELISA and quantitative real time PCR. RESULT: The expression of H2-Ab1 is higher in subjects with AR than that in controls (P < 0.05). CONCLUSION The levels of H2-Ab1 were highly increased in allergic rhinitis group, which might be associated with the pathogenesis of allergic rhinitis.

Objective To assess the safety and efficacy of the local nerve block anesthesia procedure in daysurgery inguinal herniorrhaphy practice.Methods Fifty-eight inguinal herniorrhaphy were performed under the local nerve block anesthesia in the form of day surgery between April 2014 and April 2015 other 58 inguinal hemiorrhaphy were performed under general anesthesia.Time of operation,hospitalization stay,complications and costs were evaluated.Results The average operating time of the day-surgery group was (47 ± 12) min.All operations were completed successfully.Fifty-six patients were discharged in 24 hours and 2 patients were discharged in 48 hours after the surgery.The average costs were 8437 yuan.The rate of postoperative complications was approximately 6.6％ (4/58),including hematoma(3 cases),urinary relention(1 case),and chronic pain (1 case).The VAS scores of 6 hours after the operation were (2.4 ± 0.8).Conclusions It suggests that preperitoneal hemiorrhaphy under the local nerve block anesthesia in the form of day-surgery was safe and effective.Also,it could significantly shorten the time of hospitalization and reduce medical costs.

BACKGROUND:Both of acupuncture and mesenchymal stem cel transplantation have therapeutic effects on cerebral palsy. OBJECTIVE:To explore the therapentic effect of acupuncture combined with placenta derived mesenchymal stem cel s on rat cerebral palsy. METHODS:Thirty-five Wistar rats were equivalently randomized into five groups, including control group, model group, acupuncture group, transplantation group and combination group. Rat models of cerebral palsy were prepared in al groups except the control group. At 7 days after modeling, in the transplantation group, 10μL placenta derived mesenchymal stem cel s were transplanted into the right cerebral cortex and striatum of rats;rats in theacupuncture group were given acupuncture at Shuigou (DU26), Dazhui (DU14), Baihui (DU20), Guanyuan (RN4) and Qihai (RN6) points;rats in the combination group given acupuncture and transplantation treatment as described above;the model and control groups received no treatment. Then, after 7-day intervention, the body mass, neurological function and pathological changes of rat brain tissues were measured and observed, respectively. . RESULTS AND CONCLUSION:The order of the growth rate of body mass was as fol ows:control group>combination group>acupuncture and transplantation groups>model group, and al groups had significant differences except the two groups of acupuncture and transplantation (P<0.05);findings from holding tract, foot error and water finding in maze tests showed the neurological function was best in the control group, fol owed by the combination group, as wel as acupuncture and transplantation groups, and the worst in the model group. Al groups had significant differences except acupuncture and transplantation groups (P<0.05). Besides, in the model group, cel s in the brain and hippocampus decreased, arranging disorderly with fuzzy structure, and inflammatory cel s appeared;pathological changes in the other groups were in between control group and model group, Additional y, brain tissues in the combination group exlibited better pathological changes than those in the acupuncture and transplantation groups, which were similar with the normal brain tissues. To conclude, acupuncture, placenta derived mesenchymal stem cel s transplantation, or their combination can improve neurological function in rats with cerebral palsy, especial y the combination treatment.

Objective To explore clinical value of optimizing the contrast medium injection protocol for dual-source CT high-pitch spiral acquisition in children with complex congenital heart disease.Methods Sixty patients with complex congenital heart disease were prospectively recruited and randomly divided into group A and group B by the random number table method.Patients in group A received a conventional contrast medium injection protocol,i.e.a diluted contrast material with fast and slow rate respectively,and then a flush with normal saline.The volume of contrast medium was 2.0 ml/kg.Patients in group B received an optimized injection protocol,i.e.a four-phase diluted contrast material with contrast/ saline ratio of 8:2,6:4,4:6,2:8 respectively.The volume of contrast medium was 1.0-1.5 ml/kg.Attenuation and noise were measured in superior vena cava,right atrium,right ventricle,the main pulmonary artery,left atrium,left ventricle,ascending and the descending aorta in the two groups and compared by t test.The image uniformity was assessed by t test.Subjective image quality and artifacts of superior vena cava were analyzed by the Mann-Whitney U test.Diagnostic accuracy was evaluated by x2 test.All the patients undergone the surgical treatment and demonstrated 121 abnormalities (22 species) of internal and external heart structure,i.e.56 in group A and 65 in group B.Results There was no significant difference in diagnostic accuracy between group A and group B (A:96.9％,52/56,vs.B:96.4％,62/65;x2=0.28,P=0.59).While,significant difference was found in the amount of consumed iodine between the two groups [A:(15.7±6.5) ml vs.B:(10.4±2.4) ml;t=4.14,P＜0.01].Furthermore,the image uniformity in group B was statistically higher than that in group A[A:(36.5± 18.0)HU vs.B:(272.0± 124.5)HU;t=10.30,P＜0.01].As for subjective image quality,no significant difference were observed (A:3.3±0.5 vs.B:3.5±0.5;Z=396.00,P=0.39);while significant difference was found in artifacts of superior vena cava (A:3.2±0.9 vs.B:3.7 ± 0.7;Z=300.50,P=0.02).Conclusion The optimized contrast medium injection protocol for children with complex congenital heart disease could eliminate the image artifacts of superior vena cava and improve the image quality.
