Objective To compare the effectiveness of Pregabalin given by fixed dose method and flexible dose method on treating central post-stroke pain.Methods Patients with central post-stroke pain were consecutively enrolled and randomized into fixed group and flexible group.The patients in fixed group were given pregabalin 300 mg per day for 8 weeks.The patients in flexible group were given pregabalin as follows:150 mg per day for 2 weeks, 300 mg per day for 2 weeks and 450 mg per day for 4 weeks.The primary outcome was numerical rating scale ( NRS) . The secondary outcomes included adverse effects, hospital anxiety and depression scales ( HADS ) and Athens insomnia scale ( AIS) .Results A total of 132 participants were enrolled with 65 in fixed group and 67 in flexible group from Jul 2009 to Dec 2014.Two patients in fixed group gave up the treatment while 7 patients gave up in flexible group though no significant difference was observed.Finally, 63 patients in fixed group and 60 patients in flexible group were included into analysis.There was no significant difference on gender, age, medical history between two groups. Compared with baseline, the NRS、HADS-A、HADS-D and AIS score were significantly decreased ( all P<0.05 ) .However, there was no significant difference of these scores between the two groups. Conclusion Two regimens of pregabalin showed the similar efficiency and safety to treat CPSP, however, fixed dose seemed to be more acceptable.

Objective To evaluate the value of retroperitoneal laparoscopic adrenalectomy for benign adrenal tumors.Methods From March 2003 to May 2008,78 patients with adrenal tumors received retroperitoneal laparoscopic adrenalectomy in our hospital. During the operation,three trocars were introduced into the lumbar region to establish retroperitoneal space by blunt dissection with the camera. Afterwards,the tumor was removed by using a harmonic scalpel. Results The procedures were successfully completed in all the 78 cases without blood transfusion,the operation time ranged from 45 to 180 min (mean,90 min). Drainage tubes were removed 24 hours after the operation. And the patients were discharged from hospital in 3 to 5 days postoperation. One patient showed regional subcutaneous emphysema after the surgery and was cured spontaneously. The patients were followed up for 3 to 24 months with a mean of 10 months,during which 36 patients achieved normal blood pressure in 3 months,while in the other 7 patients,oral antihypertension drugs were still needed. No patients had recurrent tumor during the follow-up. Conclusions Retroperitoneal laparoscopic can be the first choice for adrenal tumors,as it is safe and effective with minimal invasion,quick recovery,and short postoperative hospital stay.

Objective To investigate antiproliferative activity of endostatin(ES), the combining effect of Endostar and radiation on VEGF and apoptosis of the A549 human lung adenoearcinoma cell line.Methods The cell of exponential phase of growth were divided into the control, radiation alone, ES alone,radiation after ES(ES→RT), ES after radiation(RT→ES), radiation and ES at equal paee (RT+ES), γ-ray radiation at a dose of 2 Gy, single fracination irradiation, YH-16 10 μg/ml in the cell culture bottle. The combining effect was quantified by the survival curve. ELISA was used to observe the VEGF of radiation with ES on A549 cell lines. Apoptosis was observed by Hoeehst staining. Results There showed that both of ES and combining treatment had the function of antiproliferative. But the union treatment's function was more obvious (P＜0.05). The expression of VEGF in ES and the combining treatment group was more lower than others (P＜0.05). On apoptosis, the rate of apoptosis in ES, RT, combining treatment group was higher than others (P＜0.05). Conclusion On antiproliferative activity and rate of apoptosis, the combining of ES and radiation is better than to use them alone. To reduce VEGF of the A549 human lung adenocareinoraa cell line by ES could enhance radioresponse. There is no evidences to show that the expression of VEGF is concerned with the different choronological order of radiation and ES.

Objective To investigate the early diagnostic value and prognostic significance of serum presepsin in patients with sepsis.Methods A prospective observational study of 80 patients from ICU was carried out between January 2014 and June 2015.According to sepsis criteria,the cases were divided into sepsis group (n =50)and noninfectious systemic inflammation syndrome group (SIRS group,n =30), and another 25 healthy volunteers were collected as control group.Meanwhile,sepsis group was further divided into survival and death subgroups according to 28-day mortality.The dynamic changes of serum presepsin,procalcitonin (PCT),soluble myeloid cells expressing triggering receptor-1 (sTREM-1 ),C-reactive protein (CRP),interleukin 6 (IL-6)were monitored on the 1st,3rd and 7th day after admission. Results (1)The serum presepsin level of sepsis group was higher than SIRS group and control group on the 1st day,and the difference was statistically significant [912.0 (563.5,1514.8)pg/mL vs.462.0 (334.0,556.0)pg/mL vs.120.0 (70.2,320.1)pg/mL,P <0.05];(2)The area under the ROC curve (AUC)of presepsin for the sepsis diagnosis was greater than PCT,sTREM-1,CRP,IL-6.As cut-off point set at 672.5 pg/mL,presepsin measurements showed a sensitivity of 80%,specificity of 96.7%, combination of presepsin,PCT and sTREM-1 could offer better diagnostic confirmation;(3)The level of serum presepsin,PCT and sTREM-1 in death group were higher than those in survival group.The levels of serum presepsin,PCT,sTREM-1 and IL-6 in survival group gradually decreased to normal level following the therapy,but the levels of above markers in death group didn’t decrease significantly;(4)The AUC of presepsin in prognosis of sepsis prediction was greater than that of PCT,sTREM-1,and combination of the above three markers could offer better prognostic value.Conclusions Serum presepsin provided superior diagnostic and prognostic accuracy to PCT and sTREM-1,and the combination of presepsin,PCT and sTREM-1 can offer the reliable guide for sepsis diagnosis and death risk prediction.

ObjectiveTo investigate the relationship of antisocial personality disorder(ASPD) and infancy abuse.MethodsWith prospectively longitudinal research design,76 samples at infancy were initially recruited.Infancy abuse was measured by Child Protective Service records and reconfirmed by one hour family interview.56 remained samples at young adulthood were measured for antisocial personality disorder,depression,and substance abuse by utilizing Structured Clinical Interview-Ⅰ/Ⅱ (SCID-Ⅰ/Ⅱ) of DSM-Ⅳ.Longitudinal data was analyzed by multiple imputation and hierarchal regression.Results 33.9％ samples met at least one item of ASPD,38.0％ were diagnosed with substance abuse and 32.4％ with depression.Gender was correlated with ASPD symptoms (F=1.40,P =0.001 ).Infancy abuse significantly predicted ASPD (β =0.28,P=0.03 ).Further analysis demonstrated that infancy abuse was associated with ASPD with controlling substance abuse and depression (β =0.19,P =0.04 ).ConclusionInfancy abuse,with fundamental long-term effects on personality,is a risk factor for the etiology of antisocial personality disorder.The underlying mechanism might involve biological alternations.It is necessary to establish national early-life abuse monitoring and prevention system.
