Objective To compare the positive rates and complications of ultrasound?guided transperi?neal and transrectal prostate biopsies with 12+X method. Methods From January 2011 to January 2015,252 cases patients underwent ultrasound?guided prostate biopsies with 12+X method for suspected prostate carcinoma were selected as research subjects,including 114 cases were perineal puncture( transperineal group) and 138 ca?ses were transrectal puncture( transrectal group) . The positive rates and complications of biopsy were compared between the two groups. Results The positive rates in the transperineal and transrectal groups were 43. 5%( 50/114) and 41. 3%( 57/138) ,and there was no significant difference( P>0. 05) . No statistically significant differ?ences were observed between the two groups according to different PSA levels(≤4. 0,>4. 0-≤10. 0,>10. 0-≤20. 0,>20. 0 μg/L) ( P>0. 05) . There were no significant differences between two groups in complications such as:hematuria,lower urinary tract symptoms and acute urinary retention( P>0. 05) . The incidence rates of post?biopsy infection and rectal bleeding were remarkably lower(2. 6%(3/114) vs. 13. 0%(18/138),1. 8%( 2/114) vs. 11. 6%( 6/138) ,P=0. 005,0. 002) in transperineal group than in transrectal group. However,the perineal swelling rate was remarkably higher in the transperineal group than that in the transrectal group( 8. 8%( 10/114) vs. 0. 7%( 11/138) ,P=0. 003) . Conclusion Ultrasound?guided transperineal and transrectal pros?tate biopsies with 12+X method are both effective for the diagnosis of prostate carcinoma. The positive rates of the two approaches are similar,but the complications are different. The choice between the two approaches depended on the clinical features of the patients.

Objective To investigate the effect and mechanism of intravenous bone marrow stromal cells (BMSCs)transplantation against chronic ethanol-induced cognitive dysfunction in rats.Methods BMSCs from rats were isolated,cultured and identified in vitro.Male Sprague-Dawley rats(n=28)were randomly divided into control group(n=7),chronic ethanol group(n=7),BMSCs group(n=7)and PBS group(n=7).BMSCs(1×10~7 cells/animal)or PBS were intravenously injected to the rats of BMSCs or PBS group at the 7th week after ethanol gavage,respectively.All rats were sacrificed at the end of the 8th week.The learning and memory behavior was assessed using Moms water maze task.Immunofluorescence was used to examine cell proliferation maker(BrdU)in hippocampal dentate gyrus.Immunohistochemistry was used to evaluate NGF and BDNF expression in hippocampal region.Results In Morris water maze,escape latency at each time point in BMSCs group((33.83±3.26)s,(13.14±2.64)s,(6.53±0.98)s,(4.45±0.85)s)were significantly shorter than those in chronic ethanol group((53.78±4.29)s,(36.53±2.39)s,(18.28±2.13)s,(8.67±0.46)s,all P<0.01))and time percentage of platform quadrant in BMSCs group((73.99±1.49)%) was dramatically longer than that in chronic ethanol group((51.25±3.69)%),but no significant difference with contro1.The number of BrdU-positive cells in the dentate gyrus was significantly higher in BMSCs group than that in chronic ethanol group(P<0.01).Comparing to chronic ethanol gavage,BMSCs transplantation significantly increased the expression of NGF alld BDNF (P<0.01)in hippocampus.Conclusion Intravenous BMSCs transplantation is able to result in enormous attennation of the learning and memory abnormalities in chonic alcoholism rats,and which might be involved to promote hippocampal endogenous cellular proliferation by secretary neurotrophic factors.

Heart failure is a syndrom of heart disease with high morbidity and mortality .There are more and more evidence indicating immune activation developing important role in the occurrence and development of heart failure . Interleukin (IL)‐35 ,known as a negative regulatory factor of one of the members of IL‐12 family ,participates pathogenetic process of heart failure .The present article made a review for influence of IL‐35 on heart failure .

Objective To determine the median effective target effect-site concentration (EC50) of sufentanil inhibiting responses to insertion of laryngeal mask airway (LMA) when combined with propofol in the elderly patients.Methods ASA physical status Ⅰ or Ⅱ patients,aged 66-75 yr,with body mass index of 19-30 kg/m2,scheduled for elective transurethral resection of prostate under general anesthesia,were included in this study.Anesthesia was induced with propofol given by target-controlled infusion.The initial target effect-site concentration (Ce) of propofol was 1 μg/ml,and the Ce was increased by 0.5 μg/ml every 1 min until it was increased to 2 μg/ml and maintained at this level for 5 min.Sufentanil was simultaneously administered by target-controlled infusion.The target Ce of sufentanil was 0.3 ng/ml in the first patient.The concentration of sufentanil was determined using the modified Dixon's up-and-down method.After the patients lost consciousness,LMA was inserted after the target effect-site and plasma concentrations were balanced.The insertion response was defined as positive when MAP and HR increased by 20％ of the baseline value within 5 min after insertion of LMA.The Ce of sufentanil was increased/decreased in the next patient if the insertion response was positive or negative.The ratio between the two successive concentrations was 1.2.The EC50 and 95 ％ confidence interval of sufentanil blunting responses to insertion of LMA was calculated using Probit analysis.Results When combined with propofol,the EC50 (95％ confidence interval) of sufentanil blunting responses to insertion of LMA was 0.160 (0.130-0.188) ng/ml.Conclusion The EC50 of sufentanil inhibiting responses to insertion of LMA is 0.160 ng/ml when combined with propofol in the elderly patients.

OBJECTIVE To investigate the transmission process of large scale abrupt diarrhea with unknown reason occurred in hospital,analyze the cause of infection outbreak and the characteristics of Norovirus in hospital and to provide evidence to prevent and control the infection in hospital.METHODS Standardized questionnaire was used on individual,looking over the case of illness and the investigation of outbreak scene,the relationship of various contact type and odds of infection.RESULTS Nine cases were occurred,fifty-two cases were contacted,The morbidity was 17.31%.The feature of Norovirus infection was clear.CONCLUSIONS The first source of infection was an input case.The main transmission way is no protecting close contact.The high risk group is inpatients and their relatives.

Objective The aim of this study was to explore the clinical value of dual-source CT(DSCT)in the diagnosis of coronary artery fistula(CAF)before and after surgery. Methods A retrospective analysis was performed in 15 cases of patients with CAF,11 cases of which was treated by surgery during extracorporeal circulation. Results CAF arose from right coronary artery in 8 cases and left coronary artery in 7 cases,with the latter including 3 cases of ramus nodi sinuatrialis fistula,2 cases of anterior descending branch fistula,and 2 cases of left circumflex fistula. CAF entered into right atrium(6 cases),right ventricle(5 cases),left ventricle(4 cases)and left atrium(1 case). There were dilatation of coronary artery in 8 cases,localized aneurysm in 4 cases,normal coronary artery in 3 cases,single fistula orifice in 11 cases,and multiple fistula orifice in 4 cases. 11 patients underwent surgery under cardiopulmonary bypass(CPB).The postoperative imaging revealed fistula has been sutured in 10 patients with no residual fistula,including fistula vascular ligation in 3 cases,the proximal imaging and distal occlusion in right coronary artery angioplasty in 1 case,and pseudo diverticulum in 2 cases. Conclusion DSCT examination has significant value in preoperative diagnosis and postoperative follow-up for CAF.
