Objective To evaluate the clinical value of transrectal ultrasound guided systematic 13 cores prostate biopsy. Methods A total of 160 patients referred for abnormal digital rectal examination and (or) prostate specific antigen 4ng/ml or greater underwent transrectal ultrasound guided systematic 13 cores prostate biopsy.That was,in addition to the standard sextant biopsies,cores were taken from the far lateral and middle regions of the gland as described by Eskew.Pathological findings of the additional regions were compared with those of the sextant regions. Results Of the patients 35 % had cancer on biopsy(56 /160).Of the 56 patients with prostate cancer 12(21%)had carcinoma only in the additional regions,which would be undetected on the sextant biopsy technique (P

Objective To investigate the effect of repeated hyperbaric oxygen preconditioning (HOP) on the expression of hypoxia-inducible factor-1 alpha (HIF-1a) and erythropoietin (EPO) following spinal ischemiareperfusion (I/R) in rats. Methods Forty-eight male SD rats weighing 250-300 g were randomly divided into 3 groups (n = 16 each): sham operation group (S group); I/R group and repeated HOP group (HOP group). The animals in HOP group were pretreated with O2 ( ＞ 98 % ) at 2.5 ATA I h/d for 5 consecutive days at 24 h before spinal cord I/R. The animals were anesthetized with intraperitoneal pentobarbital sodium 35 mg/kg. Spinal cord ischemia was produced by cross-clamping of abdominal aorta distal to renal artery for 20 min in I/R and HOP groups. Hind-limb motor function was assessed and scored st 48 h of reperfusion. The animals were then sacrificed and the L5-7 segment of the spinal cord was removed for determination of the expression of HIF-1 α and EPO mRNA and protein and microscopic examination. Results Compared with group S, the hind-limb motor function scores and the number of normal motor neurons in the anterior horn of the spinal cord were significantly decreased, and the expression of HIF-1α and EPO mRNA and protein was up-regulated in I/R and HOP groups ( P ＜ 0.05). Compared with group I/R, the hind-limb motor function scores and the number of normal motor neurons in the anterior horn of the spinal cord were significantly increased, and the expression of HIF-1α and EPO mRNA and protein was up-regulated in group HOP ( P ＜ 0.05). The spinal cord injury was attenuated in group HOP compared with group I/R. Conclusion Repeated HOP can reduce the spinal cord I/R injury though up-regulating the expression of HIF1α and EPO in rats.

Objective To evaluate the changes of left atrial structure and function in the patients with atrial fibrillation who accepted bi -polar radio frequency current ablation .Methods All patients in our study were divided into three groups including the ones who had accept -ed bipolar radio frequency current ablation because of atrial fibrillation ,the ones who refused to accept ablation operation in despite of atrial fibrillation and the ones who maintained sinus rhythm before operation .All patients accepted TTE before and after operation .Results The rate of transverse diameter change of ablation group (24.24 ±8.67)%was larger than those of other two groups (P<0.05).Left atrial chan-nel capacity volume change rate of ablation group (17.18 ±3.26)%were larger than the values of the group who were suffering atrial fibrilla-tion but refused ablation advice (0.86 ±0.26)(P<0.05).Left atrial total ejection fractions of ablation group (202.41 ±81.59)%were lar-ger than the values of the group who were suffering atrial fibrillation but refused ablation advice (109.53 ±60.91)%( P<0.05) .And its ac-tive ejection fractions(12.18 ±3.48)%,total ejection fractions(41.31 ±8.26)%and so forth were less than the group who maintained si-nus rhythm before operation(21.33 ±5.61)%,(45.05 ±7.37)%,respectively (P<0.05).Left atrial posterior wall center and cardiac basal segment strain(14.34 ±9.47)%,(13.20 ±8.38)%,respectively,and strain rate values after operation of ablation group were less than other segments .Conclusion Left atrial structure remodeling inversion was not obviously 3~6 months after bipolar radio frequency cur-rent ablation .And at the same time ,the improvement of left atrial storage function was not obviously compared with the group who refused ab -lation advice,left atrial channel function compensation degree descended obviously left atrial co -pumping function in ablation group increased obviously,left atrial posterior wall center and cardiac basal segment systolic and distolic function were less than other segments of left .

Objective To optimize the enamel electron paramagnetic resonance (EPR) spectral processing by using the EPR spectral simulation method to improve the accuracy of enamel EPR dosimetry and reduce artificial error.Methods The multi-component superimposed EPR powder spectral simulation software was developed to simulate EPR spectrum models of the background signal(BS) and the radiation- induced signal (RS) of irradiated enamel respectively.RS was extracted from the multi-component superimposed spectrum of irradiated enamel and its amplitude was calculated.The dose-response curve was then established for calculating the doses of a group of enamel samples.The result of estimated dose was compared with that calculated by traditional method.Results BS was simulated as a powder spectrum of gaussian line shape with the following spectrum parameters:g =2.00 35 and Hpp =0.65 - 1.1 mT,RS signal was also simulated as a powder spectrum but with axi-symmetric spectrum characteristics.The spectrum parameters of RS were:g(1) =2.0018,g (11) =1.996 5,Hpp =0.335 - 0.4 mT.The amplitude of RS had a linear response to radiation dose with the regression equation as y =240.74x + 76 724 ( R2 =0.9947 ).The expectation of relative error of dose estimation was 0.13.Conclusions EPR simulation method has improved somehow the accuracy and reliability of enamel EPR dose estimation.

Objective To explore the effect of continuing nursing on the rehabilitation of patients with benign prostatic hyperplasia (BPH) after transurethral resection of prostate (TURP).Methods Toally 128 BPH patients after TURP in our hospital from May 2015 to May 2016 were evenly divided into control group and observation group by random digit table.The patients in the control group were normally guided at discharge and those in the observation group the continuing nursing was done by telephone,WeChat,QQ or family visits for 6 weeks after discharge besides normal guidance.The two groups were compared in terms of self-care ability,treatment compliance,complications and quality of life.Results After the intervention,the scores on health knowledge,self-care ability,self-care responsibility,self-care concept,self-care skills dimension of the observation group were significantly higher than those of the control group.The treatment compliance was significantly higher than that of the control group and the incidences of complications,including pain,hematuria,urinary intontinerce and retentron and infection,constipation were significantly lower than those of the control group.The scores on quality of life,physical function,role function,cognitive function,emotional function and social function score were significantly higher than those in the control group (all P＜0.05).Conclusion The continuing nursing after surgical treatment of benign prostatic hyperplasia patients can be effective in the improvements of patient's self-care ability,establishment of healthy life behavior,reduction of complications,promotion of their rehabilitation and ultimately the improvement of their quality of life.

A salt-tolerant strain GYW capable of decolorating azo dye was isolated and identified as Halo-monas sp.by 16S rDNA.The result showed that the decolorizing salt-tolerant bacteria could survive above the 10% salt concentration and it could decolorize many dyes.The strain had a high decolorizing rate on acid red GR under the condition of pH 7.5,anaerobic 30?C and 10% NaCl.The ion of Cl- strong inhibited the decolorization of acid red GR,and the ion of SO42- affected little on the decolorization,and the lycine addi-tion with the optimal concentration of 200 mg/L could enhanced the decolorization rate under high NaCl concentration.

Objective To know about the post-traumatic stress disorders (PTSD) of women with termination of pregnancy for fetal anomalies (TOPFA),and investigate the relationship of PTSD and the big five personality traits.Methods The general questionnaire,the Impact of Event Scale-Revised (IES-R) and the Big Five Questionnaire were administered to the women with TOPFA in hospital from February 2014 to February 2015.Results The total score of IES-R of 84 cases was 26.20 ± 16.38.The scores of 49 cases(58.3％) were more than 19 and that of 20 cases (23.8％) more than 35.Women who had the first pregnancy had higher level of arousal symptoms,12.84±7.41 vs.9.65±5.53 (t =2.25,P ＜ 0.05).Women whose scores were above 19 had lower adaptation,sociality,altruism and conscience compared with those scored ≤ 19,14.96±3.29,16.84±3.00,18.55±3.49,17.57±2.99 vs.13.57±2.82,18.31±2.65,20.03±2.32,18.86±2.21,t=2.02-2.33,P ＜ 0.05.The IES-R score had no linear correlation with that of the big five personalities,and intrusion subscale had linear correlation with the adaptation.Avoidance symptoms had low positive relationship with sociality in women whose IES-R were above 19,r =0.23,P ＜ 0.05.In populations whose IES-R scored above 19,avoidance subscale had positive weak correlation with sociality,r=0.31,P ＜0.05.Conclusions The women with TOPFA had high level of PTSD before termination.Women with sever posttraumatic stress symptoms had lower sociality and altruism.Moreover,of the women who had sever posttraumatic stress symptoms,one with higher sociality always had higher avoidance symptoms.
