Repeat prostate biopsy is of great significance for missed diagnosis of prostate cancer. We make a review on the independent risk factors, route selection and new techniques to improve clinicans’ cognition of prostate biopsy indications. MpMRI targeted biopsy is recommended for patients who are eligibile for repeat biopsy for higher detection rate of clinically significant prostate cancer and lower rate of non-clinically significant prostate cancer.

Objective To explore the efficacy of ZPLATE TM anterior fixation systems in the treatment of thoracolumbar fractures and dislocations.Methods 13 cases with old thoracolumbar fractures and dislocations accompanied with spinal cord injury have been treated by anterior decompression,implanting bone union and internal fixation with ZPLATE TM anterior fixation systems.Results After an average of 15 5 months followup,No plate and screw was loose and fragmentized,there is no pseudoarticulation formation,average union time are 3 7 months, and paraplegia showed different degrees of recovery.Conclusion It suggests that anterior approach provids thorough decompression and ZPLATE TM anterior fixation systems is a good spinal fixation system for the treatment of old thoracolumbar fractures and dislocations with the characteristics of strong fixation.

Objective To evaluate the different effects of the treatment of thoracolumbar fractures by pedicle of vertebral arch Tenor system and Harrington device.Methods The clinical data of 35 cases of thoracolumbar fractures were analyzed retrospectively, 23 of them were operated with Harrington device and 12 with Tenor system.Results These cases were followed up for 6 months to 2 years. The fractures treated with Tenor system got satisfied reduction, reached about 96 7% of normal vertebral height. The deformities were completely corrected and complications were significant lower than those derived from Harrington device treatment, and no delayed neurologic damage was found. Most cases got reduction with one to three Frankel grades of neurologic recovery.Conclusion The Tenor pedicle system is more effective in treatment of thoracolumbar fracture than non-pedicle device. It can get satisfied fracture reduction , reliable fixation and less complications.

Pseudomonas aeruginosa. Ziying granule can protect the mice infected by colibacillus and staphylococcus aureus and increase animal survival rate. Conclusion Ziying granule has broad-bacteriostasis effect on common pathogenic bacteria in pelvic cavity.

The 1,095 bp gene encoding peroxidase from Coprinus cinereus was synthesized and integrated into the genome of Pichia pastoris with a highly inducible alcohol oxidase. The recombinant CiP (rCiP) fused with the a-mating factor per-pro leader sequence derived from Saccharomyces cerevisiae was secreted into the culture medium and identified as the target protein by mass spectrometry, confirming that a C. cinereus peroxidase (CiP) was successfully expressed in P. pastoris. The endoplasmic reticulum oxidoreductase 1 (Ero1) and protein disulfide isomerase (PDI) were co-expressed with rCiP separately and simultaneously. Compared with the wild type, overexpression of PDI and Erol-PDI increaseed Cip activity in 2.43 and 2.6 fold and their activity reached 316 U/mL and 340 U/mL respectively. The strains co-expressed with Erol-PDI was used to high density fermentation, and their activity reached 3,379 U/mL, which was higher than previously reported of 1,200 U/mL.

Objective: To investigate the clinical efficacy of two different anterior cervical surgeries in treatment of multi-segmental cervical spondylosis. Methods: A total of 86 patients with multi-segmental cervical spondylosis were treated by anterior cervical surgery procedure. Among them, 62 and 24 cases were involved in three and four gap, respectively. Each patient underwent the surgery of long or segmented anterior cervical decompression and fixation. Preoperative and postoperative cervical curvature change, internal if xation stability, fusion rate and nerve function were evaluated. Results: All patients were successfully completed the operation, segmented surgery showed better cervical lordosis recovery, but there were no significant difference between long and segmented anterior cervical surgery in blood loss and recovery of neurological function (P>0.05). Conclusion: The segmented anterior cervical surgery has advantages in the treatment of multi-segmental cervical spondylosis.

Objective To understand the effect of health management to enhance the community hypertensive patients' self-efficacy. Method With the method of stratified random sampling, 347 patients who come from communities were diagnosed as hypertension were selected as research subjects from the range of Yingze in Taiyuan of Shanxi province. There were 191 males and 156 females, the age ranged from 38 to 72 (55.90±9.60) years. The self efficacy promotion plan was conducted on high blood pressure patients. A comparison before and after six months of health management was made among the self efficacy scores, daily life scores, health behavior scores, drug behavior scores, medical compliance behavior scores by using self-efficacy scale. Excel 2007 and SPSS 19.0 were used for data analyses. Result Before the implementation of health management, the self efficacy scores of research subjects were 26.96 ± 0.77. After the implementation of health management, the value increased to 29.51 ± 0.86 (t=-41.23, P<0.05). In four dimensions, daily life (before and after management 6.85 ± 0.20 and 7.49 ± 0.31, t=-40.66), drug behaviors (before and after management 7.52 ± 0.21 vs. 7.98 ± 0.23, t=-26.93) and medical compliance behavior scores (before and after management 5.26±0.15 vs. 6.78±0.19, t=-115.97) were higher than those before the health management except health behaviors (before and after management 7.25 ± 0.40 vs. 7.26 ± 0.40, t=-1.94, P<0.05). Conclusion Health management regulated the self care behavior of patients with hypertension, improved the patients' compliance and enhanced self efficacy, which played an important role in controlling the development of disease.

Objective To evaluate the therapeutic effect of posterior laminectomy and transfacet discectomy combined with interbody fusion and segment fixation for the treatment of lower thoracic disc herniation.Methods From June 2000 to June 2010,36 cases of lower thoracic disc herniation were treated with method of posterior laminectomy and transfacet discectomy combined with interbody fusion and segment fixation,including 23 males and 13 females,with an average of 42 years old(range,22-61 years old).The courses of disease were from 21 days to 69 months,with an average of 22 months.The lesion locations were T10-11 for 12 cases,T11-12 for 15 cases and T12L1 for 9 cases.Each of the patients underwent X-ray and MR examination,31 of them underwent CT scanning.Twenty-five cases were central protrusion type,7 cases were para-central protrusion type,4 cases were lateral protrusionstype.The clinical results were evaluated by Otanni scored system.Results The operative time was 135-220 min,with average of 155 min.The blood loss was 350-800 ml,with average of 460 ml.All patients were successfully operated without neurological symptoms aggravation and accidents.Cerebrospinal fluid leakage occurred in 12 cases,which was treated by continuous suture or dura patch repair.Two cases with giant disc herniation suffered from muscle strength decrease of lower limbs after surgery,which gradually recovered after drug treatment of hormones,dehydration,high-pressure oxygen and nerve nutrients.Postoperative X-ray examinations showed that there were no internal fixation loosening.The followed-up period was 14 days to 48 months,mean 4 months.According to Otani scored system,there were excellent results in 12 cases,good results in 18 cases and poor results in 1 case.The clinical satisfaction rate was 83.3%.Conclusion Posterior laminectomy and transfacet discectomy combined with interbody fusion and segment fixation is a safe and effective surgical procedure for the treatment of lower thoracic disc herniation.
