Purpose To explore the specific diagnostic markers of Sertoli cells and germ cells for testicular biopsy. Methods Normal testis from 3 patients who suffered from carcinoma of the prostate and treated with testis castration, and 15 testicular biopsy tissues were stained by EnVision two steps with WT-1, AR and Ki-67. Results The expression of WT-1 and AR protein were found in Sertoli cells from the 3 normal testis and 15 testis biopsy, the positive rate were all 100%, and non was positive in germ cells. The germ cell was positive for Ki-67, and the positive rate was 100%. Conclusions WT-1, AR and Ki-67 may be the specific diagnostic markers of Sertoli cells and germ cells for testicular biopsy, which may contribute to the diagnosis of testicular biopsy.

Objective:To study the efficacy of transurethral plasmakinetic enucleation and resection of the prostate (TUERP) in the treatment of patients with small and medium-sized benign prostatic hyperplasia (BPH) (<60 ml).Methods:102 clinical cases of BPH (volume <60 ml) in Renmin Hospital of Wuhan University from October 2018 to July 2020 were retrospectively analyzed. All cases were treated with TUERP. The International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), postvoid residual volume (PVR) and prostate specific antigen (PSA) were compared before and after operation. Then the operation efficiency, intraoperative blood loss and postoperative complications incidence rate were analyzed.Results:102 patients with BPH successfully completed the operation. The operation time was 34-69(52.8±8.1)min. The change of hemoglobin concentration during the operation was (10.0±4.9)g/L. The volume of prostate resection was 16.5-42(27.8±5.9)g. The postoperative pathology showed that the prostate was nodular hyperplasia. Among 102 patients, 5 patients had transient stress urinary incontinence (4.90%), 4 patients had capsule perforation (3.93%), and 2 patients had urethral stricture (1.96%). There were significant differences in IPSS, Qmax, PVR and PSA with the comparison of preoperation and postoperation (six months) (all P<0.01). Conclusions:Transurethral plasmakinetic enucleation and resection of the prostate is safe and effective in the treatment of patients with small and medium-sized benign prostatic hyperplasia (<60 ml). It has the characteristics of high resection efficiency, less bleeding, low incidence of complications and exact curative effect.

Objective:The aim of this study was to evaluate the safety and efficacy of prostatistic urethral lift (PUL) in treating benign prostate hyperplasia(BPH) through systematic review and Meta-analysis.Methods:A systematic literature search on CNKI, Wanfang, VIP, PubMed, Web of Science, Cochrane Library and Chinese Clinical Trial Registry to identify the relevant studies and data before September 2021. Information was extracted from each eligible article. All statistical analyses of this Meta-analyses were performed with Review Manager 5.3 and Stata 15.0 software to conduct a Meta-analysis of the symptom improvement of BPH patients before and 3 months and 12 months after PUL. The main evaluation indicators included: International Prostate Symptom Score (IPSS), maximum urinary flow rate (Q max), post-void residual (PVR), and Quality of Life Scale (QOL), Sexual Health Inventory for Men (SHIM). The complication rate of PUL was systematically evaluated. Results:A total of 12 clinical studies were included, and 850 patients accepted the PUL. The results showed that IPSS decreased significantly at both 3 and 24 months after PUL surgery ( MD = -11.77, 95% CI -12.47—-11.07, P<0.05; MD = -9.71, 95% CI-10.76—-8.66, P<0.05), Q max (ml/s) increased to a certain degree ( MD = 3.87, 95% CI 3.37—4.37, P<0.05; MD = 3.68, 95% CI 2.97—4.40, P<0.05), QOL decreased significantly ( MD=-2.57, 95% CI -2.76—-2.38, P<0.05; MD = -2.14, 95% CI -2.38—-2.91, P<0.05), SHIM score was unaffected ( P>0.05), compared with preoperative baseline data. PUL could be performed under local anesthesia, the main perioperative complications reported in the included studies were dysuria (17%±6%), hematuria (14%±5%) and pelvic pain (8%±6%), all of which were transient. Conclusions:PUL in the treatment of BPH has significant short-term and long-term efficacy with low surgical risk and complication rate, and can preserve normal ejaculation function. It is a safe and effective minimally invasive surgery, which can be used for BPH patients with intolerance to general anesthesia surgery or normal sexual function demand.

Ommaya reservoir implantation is generally used in the treatment of hydrocephalus and intraventricular drug administration. Ommaya reservoir implantation in the subarachnoid space of the spinal cord for the intrathecal drug administration has not been carried out in China, and only several reports can be retrieved from PubMed. About 60%-90% of untreated patients with spinal muscular atrophy type 2 (SMA2) who survive to adulthood often have complex scoliosis and joint deformities. Nusinersen is an effective drug for the treatment of SMA2. And the route of administration is intrathecal injection, which is difficult for patients with severe scoliosis. This article summarizes the process of Ommaya reservoir implantation and postoperative drug administration in a patient with complex scoliosis type SMA2, which provides a new method for clinical treatment of this disease.
