Methods The testicular transplantation were performed to cure 9 patients suffered from male hyponadism with the fetal testis with main vessel segment as donor tissue. Results Except one, 8 patients had a significantly increased level of serum testosterone, the male secondary sexual characteristics and the sexual desire were improved. The size of testis was larger than before operation. Conclusion Fetal testis transplantation with main vessel segment is a effective method to cure male hyponadism and has great value of clinical application.

Objective To compare the therapeutic effects of 1470nm diode laser vaporization prostatectomy and bipolar transurethral plasmakinetic prostatectomy (TUPKP) for treatment of benign prostatic hyperplasia (BPH).Methods From June 2015-February 2016 a total of 95 patients diagnosed with BPH were randomly divided into 2 group:52 patients were treated with TUPKP while 43 patients with 1470 diode laser.All patients were followed up with mean operative time,intra-operative blood loss,postoperative hospital stay,postoperative catheterization time,postoperative complications,international prostate symptom score (IPSS),score of life quality (QoL),maximum flow rate (Qmax),post-void residual (PVR) before and after surgery.Results Compared with data of preoperation,postoperative IPSS,QoL,Qmax,PVR in 6 months revealed significant improvement in both of two groups.IPSS of TUPKP group and 1470 group respectively dropped to 6.3 ± 2.6 and 6.7 ± 2.4.In TUPKP group,PVR reduced to 23.1 ± 20.9ml and in 1470 group decreased to 24.3 ± 19.9ml.While Qmax increased to 18.5 ± 3.1 ml/s and 18.7 ± 2.8ml/s respectively in TUPKP and 1470 group.In TUPKP group,operation time were 60.1 ± 14.9min,significantly less than that in 1470 group of 69.3 ± 12.9min (P ＜ 0.05).Compared with catheterization time in 1470 group of 33.9 ± 9.4h,the time in TUPKP group of 73.9 ± 37.6h was shorter with significant difference (P ＜ 0.05).While Curative effect of two groups of showed no significant difference (P ＞ 0.05).Conclusion The clinical curative effect of two operation methods for patients with BPH showed no significant difference.1470 group had longer operation time,while TUPKP group had less intraoperative bleeding and postoperative recovery.

Objective To investigate the value of the clinical application of fetal testis for the treatment of male hypogonadism.Method We have performed the testicular transplantation to cure 6 patients suffered from hypogonadism with the fetal testis as donor.Results All patients had a significantly increased level of serum testosterone and the male secondary sexual characteristics and the sexual desire were improved.The size of testis was larger than before operation.Conclusion Testis transplantation with fetal testis as donor is an effective method to cure male hypogonadism and has great value of clinical application for its weak immunogenicity.

Objective To investigate the relation among clinical nurses′resilience, emotional, the pressure load and self-efficacy with the 10-item Connor-Davidson Resilience Scale. Methods A total of 449 nurse in Guangzhou were recruited to investigate by 10-item Connor-Davidson Resilience Scale (CD-RISC-10), Kessler 10 Scale (K10), General Self-Efficacy Scale (GSES), Chinese Stress Overload Scale (SOS). Results The average score was 23.6±6.7 for CD-RISC-10 , 24.4±8.2 for K10,24.7±5.7 for GSES , 63.3 ±16.6 for SOS ,and the individual vulnerability scoring was (31.2±10.0) points, events load was (32.0±7.5) points. High mental toughness of nurses in general self-efficacy scores higher than that of low mental toughness group (t=-8.53, P<0.01), in the K10 dated, S0S scores were lower than low mental toughness group (t=11.23, 7.70, P<0.01). Nurse relevant regression analysis results showed that gender, general self-efficacy, K10 dated, SOS as the main factors influencing nurses mental toughness, could explain 40%of variances. Conclusions The CD-RISC-10 can better reflect the level of clinical nurses′resilience, and the gender, self-efficacy were the main effects, as well as effectively predict the nurses′emotional distress and stress level. However how to improve the toughness of the clinical nurses need more research.

Objective To evaluate the reconstruction of bladder using a segmental sinus-body of stomach on the basis of a clinical study.Methods We retrospectively reviewed the medical records,laboratory evaluations,imaging examinations,cystoscopy,urodynamic studies of 30 patients(17 men and 13 women;mean age,55 years;age range,21-69 years) who underwent the reconstruction of bladder using a segmental sinus-body of stomach.Of the 30 patients,24 had primary bladder cancer and 6 had tuberculous contracture of the bladder.Results After operation,the new gastric bladder worked well in keeping and emptying urine.All patients micturated through the urethra.The bladder capacity was 280-580 ml(mean,385 ml).The maximum urethral pressure was 20-60 cm H_2O(mean,49 cm H_2O).The filling bladder pressure was 5-15 cm H_2O(mean,12 cm H_2O).The maximum bladder pressure was 35-65 cm H_2O(mean,55 cm H_2O),and it was 28-60 cm H_2O(mean,46 cm H_2O) during urination.Qmax and post-void residual urine were 10-28 ml/s(mean,18 ml/s) and 5-85 ml(mean,20 ml),respectively.Follow-up ranged from 9 months to 24 years(mean,8.2 years).There were no disturbance of water and electrolyte metabolism,no vesicoureteral reflux,no uracratia,and no damage to renal function.Complications included perineal and vesical pain in 4 cases,enuresis in 5 cases,which gradually remitted 3-6 months after surgery,and bladder stone formation in 1 case,who underwent surgery again.At 3.5 years after surgery bladder tumor relapsed in 1 case,who then underwent transurethral resection of bladder tumor. Conclusions Our data show that the substitution of a segmental sinus-body of stomach for urinary bladder worth popularizing because of low complication rate and approximately normal urologic indexes.

Objective To study the clinical characteristics, diagnosis, treatment and prognosis of primary pulmonary peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods Two cases of primary pulmonary PTCL-NOS were studied and relevant literature were reviewed. Results Case 1 diagnosed as primary pulmonary PTCL-NOS was a 44 years old woman and disease progressed after GLD (Gem+L-OHP+ DXM) chemotherapy regimen. At last, the patient died of respiratory failure after one month. Case 2 diagnosed as primary pulmonary PTCL-NOS was a 46 years old man and reach partial response after CHOP regimen, and still alive now.Conclusion Primary pulmonary PTCL-NOS is very rare. It is easy to be misdiagnosed due to non-specific clinical and imaging manifestations. Acquiring enough tissue specimens for pathologic examination is the key to a definitive diagnosis. At present, there is no standard chemotherapy regimen for these patients, the prognosis is relatively poor.

Objective To analyze clinical features and treatment results of primary non-Hodgkin lymphoma of bone (PLB) and further to investigate the rational treatment. Methods Clinical data of 26 patients with PLB were analyzed. Twenty-three (88.5 %) patients received radiotherapy in combination with chemotherapy, three received chemotherapy alone, and three patients also received surgical resection. Results The pathological types of lymphoma in the patients were diffused large B-cell iymphoma (DLBCL) in 15 patients (57.7 %), small B-cell lymphoma in 1 patient(3.8 %), B-cell lymphoma with unclassified subtypes in 4 patients (15.5 %), T-cell lymphoma in 5 patients (19.3 %,among which anaplastic large cell lymphoma in 3 patients), and unclassified lymphoma in one patient (3.8 %). Of the 26 cases of PLB, 15 were at stage Ⅰ, 3 at stage Ⅱ, 3 at stage Ⅲ and 5 at stage Ⅵ. The 3- and 5-year overall survival rates were 59.16 % and 31.37 %respectively. In the eleven patients who died of lymphoma, three had Iocol-regional relapse, and nine had systemically involved lymphoma. The radiation-induced bone fracture had not been observed after local radiotherapy with median dose of 50 Gy. Conclusion Pelvis maybe a common primary site of PLB, and DLBCL type are the most observed histological subtype. The optimal treatment for PLB is radiotherapy combined with chemotherapy. Local regional radiotherapy with median dose of 50 Gy can be safe and feasible.

Objective To study the effect and histocompatibility of urethral extracellular matrix in repair of traumatic urethra defects in rabbits. Methods Model of traumatic urethral defects was made by resecting 1.0-1.5 cm segment of the urethra in 20 rabbits. Then, the defects were repaired by a tube of extracellular matrix of the same length. The dynamic changes of CD4+, CD8+ T cell and CD4+/CD8+ in peripheral blood were detected by flow cytometry at 1,2, 3 and 4 weeks after operation. In the meantime, the immunity response of rabbits was evaluated by lymphocyte transformation test. The repaired segments stained with hematoxylin-eosin (HE) and Van Giesen were studied by histologic and pathologic observations at 10 days, 3, 6 and 24 weeks postoperatively. The urodynamics, urethroscopy and urethrography were performed at 24 weeks postoperatively. Results There was no significant difference in aspects of stimulative index of lymphocyte transformation, T lymphocyte subsets CD4+, CD8+ T cell and CD4+/CD8+ between experimental group and negative control group. Urothelium covered the whole surface of the matrix tube three weeks after operation. The smooth muscle cells increased nearly to normal urethral wall at 24 weeks. Urethrosoopy and urethrography showed glossy matrix tube. There was no statistical difference upon urodynamies between experimental group and control group. Conclusion The urethral extracellular matrix has good histocompatibility and may be a safe and effective material for repairing urethra defects.

Objective To observe the effects of Triptolide on the expression of toll-like receptor 4 (TLR4) in renal ischemia/reperfusion (I/R) injury in rats. Methods A renal I/R model was established. Rats were randomly separated into the following experimental groups. Group 1, shamoperated control (n = 15) : rats were subjected to surgical manipulation, without the induction of renal ischemia. Group 2, I/R (n = 18): rats were subjected to left renal ischemia for 45 min followed by reperfusion. Group 3, TRI + I/R (n = 18): Before the I/R procedure (as in group 2), rats were intraperitoneally injected with TRI (0.4 mg/kg), once every day, three times. Rats were killed at the 1st, 3rd, and 5th day after I/R injury. The parameters of renal function were determined by autobiochemical analyzer. The expression of TLR4 was detected by RT-PCR and Western blotting. Results As comparedwith the sham-operated control group, serum BUN and Cr levels were significantly increased in the rats undergoing I/R procedure at the 1st, 3rd, and 5th day (P＜0. 01). After the treatment with TRI, the levels of BUN and Cr and the expression of TLR4 in the renal tissues were significantly decreased (P＜0. 05). Conclusion TRI could relieve renal I/R injury in rats by inhibiting the TLR4 expression.

Objective To evaluate the predictive value of urinary neutrophil gelatinase-associat-ed lipocalin (NGAL) and interleukin-18 (IL-18) for delayed graft function (DGF) in kidney transplan-tation. Methods Serial urine samples collected at 0, 12 and 24 h after operation from 86 kidney transplantation patients were analyzed by enzyme-linked immunosorbent assay for NGAL, IL-18 and RBP. Results Fifteen patients developed DGF. At 12 h after transplantation, the level of urine NGAL elevated significantly (1712.75±474.6 vs. 863.1±199.8 without DGF, P<0. 001). The in-creases of urine IL-18 (29. 2±4.1 vs. 28.7±4.2 without DGF, P>0. 05) was not significant. At 24 h, both urine NGAL(2905.0±1108.1 vs. 911.8±221.0 without DGF,P<0. 001) and IL-18(211.3± 34.0 vs. 86.9±22.8 without DGF, P<0. 001) increased significantly, whereas the changes of urine RBP and serum creatinine (SCr) were not significant. ROC analysis showed that the area under the curve of NGAL and IL-18 were 0. 90 and 0.76 respectively, the cut-off values were 996.5 ng/mg and 148.5 ng/mg, the diagnostic sensitivities in DGF were 90.2% and 76.3%, specificities were 82.6% and 66.4% respectively. Conclusions Both urine NGAL and IL-18 could potentially be early predic-tive marker of DGF. The level of NGAL elevated earlier than IL-18, which may be more effective in predicting DGF.
