To approach the criminal characteristics and responsibility of murder committed by psychotics.Case control study between psychotic(74 cases)and non psychotic(77 cases)were studied.The murders committed by psychotics were characterized with the abruptness,overt and cruelty.The symptom of delusion(47 2%)and auditory hallucination(31 1%)contribute the major causes of committing murder.Murderer with schizophrenia rank the first,while who with the manic depressive psychosis rank the second(14 8%).The criminal characteristic and intent of murder are the basis for assessment of criminal responsibility.

This work observed on isolated perfused rat hearts, that 10~(-9)mol/L endothelin (ET) induced myocardial contracture, decrease of heart function and coronary flow, intramyocardial Ca~(2+) accumulation and Mg~(2+) loss and etc. These cardiac action of ET were obviously more prominent when Mg~(2+) in the perfusion fluid was lowered to 0.12 mmol/L, and were significantly alIeviated when Mg~(2+) content was increased to 4.8mmol/L (normal plasma Mg~(2+) content is about 1.2 mmol/L). The mechanism of the Mg~(2+) effect on the cardiac action of ET may be related to its inhibition of Ca~(2+) influx into the myocytes. These results suggested that without magnesium defficiency, suitable replenishment of Mg~(2+) probably have practical clinical significance in the prevention and therapy of myocardial injury occurred during diseases with elevated circulatory ET level.

Objective To evaluate the clinical value of computed tomography (CT) examination in the etiologic diagnosis of small bowel obstruction.Methods From January 2010 to September 2013,a total of 237 patients with small bowel obstruction confirmed by operation were enrolled.The clinical data of all patients were collected.The diagnostic value of color Doppler ultrasound and abdominal CT examination were compared in estimating site of obstruction,etiology of obstruction and strangulation obstruction.Chi square test was performed for count data comparison.Results Among 237 patients with small bowel obstruction,there were 121 patients with data of both color Doppler ultrasound and abdominal CT examination.After operation,it was comfirmed that the accurate diagnosis rates of abdominal CT scan in the site of obstruction,the etiology of obstruction and strangulation obstruction were 75.2 ％ (91/121),66.1％ (80/121) and 87.2％ (41/47),respectively,and which were higher than those of abdominal color ultrasound (44.6％,54/121; 30.6％,37/121 and 42.6％,20/47).The differences were statistically significant (x2 =23.555,30.595 and 20.593,all P＜0.01).Conclusion The accurate diagnosis rates of abdominal CT scan in estimating the site of obstruction,the etiology of obstruction and strangulation obstruction were higher than those of color Doppler ultrasound,especially with obvious advantage in judging the etiology of obstruction.

OBJECTIVE To investigate the qacA/B genes in meticillin-resistant Staphylococcus aureus(MRSA) and their significance.METHODS Totally 221 MRSA strains were clinically isolated.The genes of qacA/B were analyzed using polymerase chain reaction(PCR).RESULTS From them 101 strains were found the qacA/B genes,the positive rate of qacA/B genes was 45.7%.And 71 strains were selected for qacA PCR detection,20(28.2%) were with qacA gene and 27(38.0%) were with qacA/B gene,suggesting that the seven strains be with qacB gene.CONCLUSIONS MRSA strains have emerged the high-frequency qacA/B disinfectant resistance gene.Application of chlorhexidine and other disinfectants to prevent postoperative nosocomial infections must be reassessed.The efficacy of existing disinfectants or disinfection methods should arouse our wider attention.Disinfectant resistance gene detection technology provides a practical means for the research of the disinfectant-resistant bacteria and the clinical application of the molecular epidemiology research.

BACKGROUND:Immunologic injury is a main pathogenesis of chronic rejection,and it is related to multiple immunological associated-gene polymorphism,in particular,transforming growth factor-β1 gene polymorphism.Recently,there are a lot of researching results of the relationship between TGF-β1 gene polymorphism and chronic rejection.OBJECTIVE:To study the relationship between TGF-β1 genotypes and the chronic renal allograft rejection in recipients and donors.DESIGN:Prospective case analysis.SETTING:Department of Urinary Surgery,Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA;General Organ Transplantation Center.PARTICWANTS:A total of 144 recipients and 65 out of 114 donors(another 30 cases did not have the blood preparation)were selected from Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from Jane 2000 to May 2001.The surgical program was approved by the local ethics committee.METHODS:The TGF-β1 genotypes were detected in 144 recipients before renal transplantation and 65 out of 114 donors by sequence-specific primer polymerase chain reaction.The follow-up lasted for 5 years in recipients after surgery to survey chronic renal allografi rejection;furthermore,the effects of genotypes of recipients,genotypes of donors,and the genotype combination on transplanted renal function were analyzed.MAIN OUTCOME MEASURES:(1)Inciderce of chronic renal allograft reiection in recipients and donors with difierent TGF-β1 genotypes;(2)incidence of chronic renal allograft rejection in recipients and donors with TGF-β1 genotype combination.RESULTS:(1)Incidence of chronic renal allograft rejection in recipients with high-secretory TGF-β1 genotype was significantly higher than that in those with moderate-secretory or low-secretory TGF-β1 genotypes(x2=10.091,P<0.01).There were no significant differences in chronic renal allograft rejection among donors with different TGF-β1 genotypes(x2=0.002,P>0.05).(2)Chronic renal allograft rejection occurred in the recipients with high-secretory TGF-β1 genotype,whose donors also had high-secretory TGF-β1 genotype,and the incidence of chronic renal allograft rejection was significantly higher than that in other recipients with TGF-β1 genotype combination(x2=4.352,P<0.05).While the incidence of chronic renal allograft rejection in the recipients with moderate-secretory and low-secretory TGF-β1 genotypes,whose donors also had moderate-secretory and low-secretory TGF-β1 genotypes was significantly lower than that in other recipients with TGF-β1 genotype combination (x2=4.134,P<0.05).CONCLUSION:The TGF-β1 gene polymorphism is detected in the recipients and donors before renal transplantation to benefit for along-term prognostic factor for chronic renal allograft ejection and an ideal genotype combination between recipients and donors.

Objective To study the methodology of the ear reconstruction using Medpor framework. Methods Using Medpor material as ear framework, 112 cases of ear reconstruction were performed using the expanded skin flap on the mastoid region(method Ⅰ) and the temporal fascia flap adding skin graft ( method Ⅱ) to cover ear framework. Twenty-three cases adopted method Ⅰand 89 cases adopted methodⅡ. Results One hundred and nine cases of the reconstructed ear were successful with a good appearance and 3 cases were failure. The exposure of Medpor framework occurred in 17 cases in this series. Among them the method Ⅰ occurred in 8 cases (34 %) and the method Ⅱ was used in 9 cases (10%). The exposure of Medpor framework in 14 cases were repaired using local skin flap or local fascia flap and skin graft. In 3 cases Medpor framework had to be removed due to the sever exposure. Conclusion It seems that Medpor framework is a good alternative for the ear reconstruction.

Objective To explore the validity and security of Simulect (basiliximab) induction immunosuppressive therapy in terms of prevention of acute allograft rejection in sensitive recipients.Methods Thirty-six adult recipients of cadaveric kidney transplant with panal reactive antibody 30 %～ 50 % were assigned randomly in a 1∶1 ratio to receive either two doses Simulect or matching placebo. Both patient groups also received baseline triple immunosuppression with the cyclosporine microemulsion, MMF and steroids. A total 40 mg Simulect was given in two doses of 20 mg eachon day 0 about 2 h before transplantation and the day 4 after transplantation respectively.Results No hyperacute rejection and delayed graft function occurred in the two groups. No apparent adverse and toxic events were recorded in the Simulect group. The incidence of acute rejection 3 months after transplantation was 11.1 % in Simulect group compared with 50 % in the placebo group ( 77.8 % reduction, P
