Objective To compare the efficacy of amisulpride and other SGAs in treating the negative symptoms of Schizophrenia.Methods The randomized controlled trials (RCTs) about Schizophrenia treated with amisulpride and other SGAs from Jan 1995 to Mar 2013 were searched in The Pubmed,EMbase,Cochrane Library,WanFang Data,CNKI and VIP.Two reviewers independently screened the literatures,extracted the data,and evaluated the methodological quality.Than meta-analyses were conducted by using RevMan 5.1 and Stata 12.0 software.Results The totall3 RCTs were included.Among the 1814 patients involved.The results of meta-analyses showed that the score of PANSS-N was no significant differences between two groups (MD =-0.33,95％ CI:(-0.87,0.21),Z =1.20,P =0.23) ; and the score of SANS was no significant differences between two groups (MD =-0.21,95％ CI:(-1.51,1.50),Z =0.31,P =0.76).The side effects were more in other SGAs group than those in amisulpride group.Conclusion Amisulpride is as effective as other SGAs for the treatment of schizophrenia with predominantly negative symptoms,and it has more advantage than other SGAs in safety.

Objective To investigate the relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P ＜ 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P ＜ 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P ＜ 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ～ 0.48,P ＜ 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ～-0.51,P＜0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.

Objective To study the imaging features of sacroiliac joints(SIJ) in patients who were misdiagnosed as spondyloarthritis(SpA).Methods A total of 34 patients with chief complaint of back pain and misdiagnosed as SpA from January 2007 to April 2013 in Department of Rheumatology Chinese PLA General Hospital were enrolled.The imaging,clinical manifestations,laboratory examinations data were analyzed.Result The main reason for misdiagnosis as SpA was because of sacroiliitis presenting on imaging.The final diagnoses included 24 patients as SIJ infection,4 patients as neoplastic diseases,2 patients as metabolic bone diseases,2 patients as sacroiliac joint degeneration,1 patient as gout of sacroiliac joint,1 patient as diffuse idiopathic bone hypertrophy.For patients with infection,there were 10 patients receiving X-ray and 22 patients receiving CT of SIJ.However,5 and 7 patients had negative results respectively.These patients with infection had abnormalities in MRI including all with bone marrow edema,21 patients with erosion of bone and joint,22 patients with muscle involved.As to the patients with malignancies,SIJ CT scan appeared normal.Bone marrow edema and erosion in MRI were found in all neoplasm patients expect one as ependymoma.Adjacent muscles were involved in the patient with Ewing's sarcoma.Either X-ray or CT in other patients demonstrated obvious abnormalities,but only mild erosion of bone was found in MRI.Conclusion Bone marrow edema of SIJ in MRI represented not only in patients with SpA.Rheumatologists should analyze the clinical manifestations and laboratory examinations comprehensively in order to avoid the misdiagnoses.

This study was designed to summarize the clinical experience of harvesting the lung of a brain-death donor by international standardized methods so as to establish a set of standards and regulations that are applicable for harvesting the lung of brain-death donors in China. The patient was strictly determined according to international standardized method by two or more advanced neurologists, neurocranial surgeon, anesthetists, and ICU specialists using brain death diagnostic standards and brain death diagnostic technological specification. The family members signed a informed consent of abandoning treatment for brain death and he was a volunteer organ donor. The operation was performed on 1 brain-death donor who had endured 50 hours of mechanical ventilation to evaluate brain death and organ function. The donor was assessed by donor lung function test and international brain death standard. Then the organ was ready for lung transplantation.

Object To develop a new method of discriminating the principle components of Radix Paeoniae Rubra (RPR) from different areas, and to find the reason for forming high-quality of RPR in the place of the genuine. Methods Using Foruier transform infrared (FTIR) absorption spectrometry, the characteristic peaks of fingerprint infrared spectra of RPR samples from 18 habitats were recognized and compared. Results Frequency, intensity and shape of infrared absorption spectra were obviously different between wild and cultivated groups of RPR. The infrared absorption peaks of RPR in Duolun, a famous Chinese orthodox drug, were of distinct characteristics. Conclusion FTIR technique is first applied to rapid analysis of principle component of RPR from different areas. So an operable method in the quality control and discrimination of RPR in the place of the genuine is provided.

Objective To summarize the clinical experience ot harvesting and using the lungs from donation after brain death (DBD) and donation after cardiac death (DCD,Maastricht category Ⅳ) in China.Methods Eleven potential DBDs and DCDs were evaluated by our transplant group preoperatively,including 6 cases of DCDs and 5 cases of DBDs,and all of them received the tests of sputum culture bedside bronchoscopy,chest X rays,and blood gas analysis.After clear evaluation,1 case of DCD and 2 cases of DBD were discharged from the group for bilateral inflammatory infiltration and poor oxygenation index,and one case of DCD was precluded due to long warm ischemic time (＞60min).The donor lungs from remaining 7 cases were harvested successfully after the declaration of brain death or cardiac death.The preoperative lymphocytotoxic cross match test was negative,ABO blood types were compatible,and the donors were all suitable for the transplant procedure.Results Seven lung transplants were performed successfully under ECMO support,including 5 cases of bilateral lung transplantation and 2 cases of single lung transplantation.One patient was complicated with severe infection and died of sepsis on postoperative day (POD) 39,and one was succumbed to multiple organ failure.Two patients suffered of acute rejection on POD 30 and POD 19,respectively,and obtained improvements by bolus steroid therapy.The remaining 3 patients all recovered uneventfully.During a follow up period,all the patients lived an active life style with high quality of life.The mean survival time was 23.3 months (3-51 months).Conclusion The DCD and DBD may be one of the available donor resources for lung transplantation after efficient management of the potential donors and detailed preoperative evaluation in China.

ObjectiveTo evaluate the security and effectiveness of raffinose-low potassium dextran solution (RLPDs) for donor lung preservation.MethodsFrom Sep.2002 to Dec.2011,131patients underwent lung transplantation in our institution,including 81cases of single lung transplantation and 50 cases of bilateral lung transplantation.There were 95 males and 36 females.A total of 129 donors were used for organ harvest.Two donors denoted their lungs to four patients receiving single lung transplantation. All the donors were flushed, perfused antegradely and retrogradely,and preserved with hypothermal RLPDs.The repeated reperfusion was necessary when the cold ischemic time was fairly long and the function of donor was poor.During operation,the blood gas analysis,mean pulmonary artery pressure (mPAP) and breathing mechanics were monitored.Postoperatively,all the recipients received re-examination of cardiac ultrasonography,pulmonary function,blood gas analysis and chest imaging.ResultsAll lung transplantations were performed successfully,with a mean cold ischemic time of (193±21) min (range,65-630 min).There was a significant relationship between postoperative pneumonedema and donor lung cold ischernic time (P＜0.05),which was also observed between postoperative pneumonedema and primary graft dysfunction (P＜0.01). The blood gas analysis and oxygenation index were significantly improved postoperatively,with the mPAP and parameters of breathing mechanics being descended to a normal level.There were 24 early deaths in the first month post-transplant,with a mortality of 18.3％ (24/131),including 11cases of sepsis,7 cases of primary graft dysfunction,3 cases of heart failure,1case of bronchial stomal leak,1case of acute rejection,and 1case of pulmonary infarction.The pulmonary function was improved significantly 3 months postoperatively.Conclusion RLPDs is efficient in the preservation of donor lung,with the ability to alleviate ischemic reperfusion injury and improve pulmonary function.

Objective The purpose of this study is to select suitable ages of rats for the CPR ( cardiopulmonary resuscitation) animal model.The neurological function score and subgroups analysis are evaluated in 2 month old and 4 month old animal groups.Methods Based on the evaluation of physiological indexes including ECG, blood pressure and neurological function defect score ( NDS) and subgroup analysis, the stability of CPR rats model was compared between 2 month old and 4 month old animal groups.Results The results showed that, the model rate of the ventricular fibrillation was induced by electrical stimulation , the 4 month old group was 87.5%, significantly higher than the 2 month old group, however, there was no significant difference between the two groups in the mortality rate;For the changes of blood pressure during the process of CA( cardiac arrest) induced by electrical stimulation, the 4 month old group was significantly lower than the 2 month old group (P <0.01); for the NDS at each time point after CPR, there was no significant difference between the two groups; however, the NDS subgroup analysis at different time points showed that there were different degrees of differences between the two age groups ( P <0.05) .Comparing with the 2 month old group, the 4 month old group had a stable process during the animal model preparation, had an obvious cerebral blood hypoperfusion phenomenon and aggravation of brain injury after CPR.Conclusion The 4 month old rats are more suitable for preparation of CPR animal mode , the model rate is high, the brain injury aggravate.It is more suitable evaluation for basic research and treatment of CPR.
