Percutaneous neprolithotomy (PCNL) is the preferred method for the treatment of the majority of urinary calculi, especially for the calculi lies in the renal and upper ureteral.Recently, a number of trials were applied into TPCNL, such as, decrease the nephrostomy and indwelling externally grooved ureteral stent, internal ureteral catheter and not aiming replace the preventive use of renal tube.TCNL has its advantages in postoperative pain, hospitalization time and postoperative recovery than standard percutaneous neprolithotomy.

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF super family found in recent years, which widely exists in the body tissues and participates in the immune regulation, immune stability, and immune surveillance of the human body. The TRAIL receptor is expressed in the surface of a variety of cells. Recent studies show that TRAIL induces the apoptosis of tumor cells and has no significant toxic effect on normal cells. Its anti-tumor activity and safety have been widely recognized. The development of prostate cancer is regulated by the mechanisms of cell apoptosis. TRAIL can induce the apoptosis of prostate cancer cells, and therefore has a great application value in the treatment of prostate cancer.

According to the latest data from the National Cancer Center of China, prostate cancer (PCa) has become the highest incidence tumors of urinary since 2008, and its incidence and mortality has occupied great attention in the past decades. Therefore, the choice of safe and effective diagnostic method, to detect the occurrence of PCa, is necessary. The way of clinical diagnosis mainly includes digital rectal examination, serum PSA, transrectal ultrasound, MRI spectroscopy imaging, and prostate biopsy, ect. Prostate biopsy is the most reliable diagnosis method and agold standardfor the diagnosis of PCa. The systematic use of the prostate biopsy has greatly improved the diagnosis of PCa. However, there are several prostate biopsy scheme and scholars proposed a variety of programs on the choice of puncture point. It has not yet formed a standard method at this stage. In this study, we will review the development of prostate biopsy and the status recent research to explore application value of different method.

Objective To study the reliability of Gleason score by prostate biopsy with prostatic cancer(PCa)in prediction of tumor location and analyse related influencing factors of positive surgical margins after radical prostatectomy.Methods The retrospective study recruited 72 patients with PCa who had been diagnosed by trans rectal ultrasound-guided prostate biopsy,and eventually treated with laparoscopic radical prostatectomy.The correlation of each index were analyzed by statistical software.Results In this study,Kappa test indicated a good agreement that Gleason score between prostate biopsy and radical prostatectomy.Biopsy positive more focused on four peripheral points near the bottom.Biopsy tumor location was not suitable for predicting tumor distribution.Biopsy Gleason score and biopsy positive percentage in biopsy specimen were independent predictors of positive surgical margins.F and L points had good correlation with the positive surgical margins.Conclusion The biopsy Gleason score is a good evidence to pathological grading in patients.These information will lead to positive surgical margins rise possibly:needle biopsy Gleason score exceed 7.25,positive biopsy percentage more than 45% and the location positive biopsy close to prostate apex.

Objective To evaluate the effectiveness of interventional procedures in the treatment of acute pulmonary embolism(PE). Methods Pulmonary arterial thrombolytic therapy, suction and fragmentation of thromhi, anti-spasm, and balloon dilation were performed in eighteen cases with clinically highly suspected PE confirmed by emergent pulmonary artery angiography beforehand. Wedged pulmonary arterial pressure, pulmonary recanalization rate, the display ratio of distal pulmonary capillary net, blood gas analysis, blood oxygen saturation, and the improvement of clinical symptoms and signs were used for evaluation of the effectiveness. Seventeen of the alive cases with dislodgement of deep vein thrombi of the lower extremities were confirmed for the formation of PE and then thrombolytic treatment of the thrombotic deep vein was performed after the placement of inferior vena cava filter. Results Pulmanory artery angiographies showed embolism of the pulmonary arterial trunks or more than two of the branches. The post-treatment pulmonary patency reached 80%-90% in three cases, 90%-95% in eleven cases and 100% in five cases. The display ratio of distal pulmonary capillary net was over 90% in all the cases. Wedged pulmonary arterial pressure decreased to below 25 mmHg in thirteen cases, and to 25-30 mmHg in five cases. Blood oxygen saturation rate improved immediately to 90%-95% in ten cases and to 95%-100% in eight cases. Cough, hemoptysis, dyspnea, and chest pain were completely relieved in thirteen cases and significantly relieved in five cases. Digestive track bleeding was complicated in one case. Conclusions Pulmonary artery angiography is the golden standard for the diagnosis of pulmonary embolism. Interventional therapy is very effective for acute pulmonary embolism, which can significantly reduce the mortality rate.

Methods The testis of newborn mouse were digested by modified two step digest method, and the type A spermatogonia cells were separated by different adhesive time with Sertoli cells. Results High concentration (95%) purified type A spermatogonia cells were acquired, and the spermatogonia transplanting experiment demonstrated the efficiency of the method.Conclusions This method is easy and efficient to isolation and purification of spermatogonial stem cells.

OBJECTIVETo explore the efficacy and safety of prostatic arterial embolization (PAE) in the treatment of benign prostatic hyperplasia ( BPH) in high-risk aged males.

METHODSWe retrospectively analyzed the clinical data about 21 high-risk BPH patients aged 77-91 (mean 80) years treated by PAE.

RESULTSPAE was successfully performed in all the 21 patients, with the operation time of 90-120 min. At 2 weeks, 3 months, 6 months, and 12 months after surgery, the International Prostate Symptom Scores (IPSS) were 18.3 ± 3.1, 9.8 ± 2.7, 9.4 ± 2.5, and 10.1 ± 2.2, the quality of life scores ( QOL) were 4.6 ± 1.4, 4.3 ± 1.2, 4.6 ± 1.1, and 4.9 ± 0.6, the maximum urinary flow rates ( Qmax) were (12.5 ± 2.5), (15.8 ± 2.4), (16.6 ± 2.2), and (16.3 ± 1.8) ml/s, and the postvoid residual urine volumes (PVR) were (35.0 ± 3.4), (13.0 ± 3.3), (10.0 ± 3.0), and (8.0 ± 2.5) ml, respectively, markedly improved as compared with the baseline (IPSS: 24.5 ± 3.7, QOL: 5.7 ± 1.6, Qmax: [8.3 ± 2.1] ml/s, and PVR: [98.0 ± 11.0] ml), with statistically significant differences in IPSS, QOL, Qmax, and PVR (all P < 0.05). The maximal velocity of blood flow in the prostate was obviously decreased and the prostate volumes were (74.4 ± 4.8), (42.5 ± 4.4), (38.3 ± 4.0), and (36.7 ± 3.5) cm3 at 2 weeks, 3 months, 6 months, and 12 months, respectively, also significantly reduced in comparison with (84.3 ± 5.4) cm3 preoperatively (all P < 0.05).

CONCLUSIONPAE is a safe and effective option for the treatment of BPH in high-risk aged males.

OBJECTIVETo investigate the occurrence and associated factors for posttraumatic stress disorder (PTSD) in rescuers and firefighters.

METHODSThe PTSD of 264 rescuers and firefighters who had participated in rescue was evaluated using the self-designed fireman general situation questionnaire and PTSD Checklist-Civilian Version (PCL-C). The factors associated with the occurrence of PTSD were also analyzed.

RESULTSThe incidence rate of PTSD in the subjects was 8.3%. The PTSD rate of special service corps (12%) was significantly higher than that of other subjects (P<0.05). The incidence of PTSD was highest in the rescuers and firefighters above the third rank, but without significant differences (P>0.05). The PTSD rate of married rescuers and firefighters was significantly higher than that of unmarried subjects (P<0.05). The PTSD rate of subjects addicted to drinking was significantly higher than that of non-drinking subjects (P<0.05). Subjects with more frequent attendance were more susceptible to PTSD compared with those with less attendance.

CONCLUSIONThe incidence rate of PTSD is high in rescuers and firefighters who have attended rescues. It is necessary to implement both short-term and long-term counseling programs for stress management and intervention in order to reduce the psychological trauma after rescue and improve the mental health of rescuers and firefighters.
