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.

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.

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.

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 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 summarize the clinical experience of harvesting and using the lungs of cardiac death donor.Methods The lungs from donation after cardiac death (DCD) were harvested and used for lung transplantation.The donors suffered from severe craniocerebral trauma or brain neoplasms and were identified after cardiac death post declaration of brain death.Written consent about DCD was obtained from the consanguinities.The donor lungs were harvested after clinical evaluation of donors with considerable function and after the determination of DCD.The preoperative lymphocytotoxic cross match test was negative,ABO blood type was compatible,and the donors were all suitable for the transplant procedure.Results Two bilateral lung transplantations and one single lung transplantation were performed,with the warm ischemic time being 23,27,and 32 min,respectively.The operative course was uneventful The ICU stay was 31,18,and 26 days respectively,with dramatic improvement of pulmonary function postoperatively.Acute rejection occurred in two cases,which was treated with bolus of corticoids.There were no infection in our 3 patients,and the life quality was satisfactory during the follow-up period.Conclusion The lung from DCD may be one of the available resources used for lung transplantation on the basis of efficient management of the potential donors and clear evaluation of the donors.

Objective To explore the potential pathogenesis of Yersinia pestis and provide new clues for vaccine development through comparative proteomic analysis of wild-type and pCD1 cured strain of Yersinia pestis 201.Methods Differentially expressed proteins at 26℃ and 37℃ were separated and identified using two-dimensional electrophoresis coupled with mass spectrometry .Results A total of 24 differently expressed proteins were successfully identified from the samples of bacteria grown at 26℃ and 25 proteins at 37℃.Among these, 7 proteins were encoded by pCD 1 plasmid. Conclusion Through comparative proteomic research, we have found that the abundance of several proteins can be dramatically changed when the large plasmid pCD 1 is missing,suggesting that the plasmid can regulate the expression of many genes located in the chromosome .

Objective To study the clinical and imaging characteristics of patients with infectious sacroiliac arthritis.Method Twenty-one patients diagnosed with infectious sacroiliac arthritis were analyzed retrospectively between 2000 and 2014.The chief complaint was pain in hip and lumbosacral area.Their clinical features,laboratory tests and pathological examination results as well as CT/MRI/PET-CT images were evaluated.Results There were nine males and thirteen females eighteen (85.7％) patients had unilateral sacroiliac joint involvement.Among these patients,three were diagnosed with brucellosis sacroiliac arthritis(BSI),eight patients with tuberculosis sacroiliac arthritis (TSI),and ten patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis (ISI).For those patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis,white blood cell count,erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)were dramatically increased.Twelve patients were diagnosed pathologically including 6 ISI,2 BSI and 4 TSI.Twelve patients and seventeen patients were scanned by CT and MRI respectively.Two patients undertook PET-CT examination.Antibiotic therapy showed significant therapeutic effects in all patients.Conclusion Infectious sacroiliac arthritis patients with hip or lumbosacral pain as the chief complaint can be easily misdiagnosed as spondyloarthritis.Comprehensive analysis of clinical features,imaging and laboratory findings is essential for accurate diagnosis.
