BACKGROUND: The cryopreservation of human ovarian tissue has become an attractive method to preserve female fertility. Human ovarian tissue experiences neovasculadzation after transplantation to recover blood supply, cryopreservation and resuscitation technique is a key for the neovascularization of human ovarian tissue following transplantation. OBJECTIVE: To investigate vascular endothelial growth factor (VEGF) expression and microvessel density in human ovadan tissue following novel needle immersed vitrification (NIV) and slow-freezing, to explore the influence of two cryopreservation methods play in the neovascularization of human ovarian tissue after transplantation. METHODS: Eight normal human ovarian tissues from patients with carcinoma of endometrium were cut into 12 fragments in the size of 1.5 mm × 1.5 mm × 1.0 mm, then randomly assigned to 3 groups: fresh control group, NIV group and slow-freezing group. In the NIV group, pieces of ovarian tissue stdps were dehydrated in an equilibration solution consisting of 7.5% ethylene glycol and 7.5% dimethyl sulfoxide in TCM-199 supplement with 20% fetal bovine serum and a vitrification solution consisting of 15% ethylene glycol, 15% dimethyl sulfoxide and 0.5 mol/Lsucrose, then were plunged in liquid nitrogen directly and sealed in liquid nitrogen-filled cryovials. For thawing, the needles holding ovadan tissues were serially transferred into 1.0, 0.5, 0.25 mol/L sucrose solution and TCM-199 supplemented with 20% fetal bovine serum. In the slow-freezing group, pieces of human ovadan cortex fragments were placed in a 1.8-mL cryovial containing 1 mL of TCM-199 medium supplemented with 0.1 mol/L sucrose, 20% fetal bovine serum and 1.5 mol/L dimethyl sulfoxide, the cryovials were placed in the programmable freezer and cryopreserved by preset slow-cooling protocol. For thawing, the ovarian tissue stdps were washed in a stepwise manner: 1.0 mol/L dimethyl sulfoxida + 0.1 mol/L sucrose, 0.5 mol/L dimethyl sulfoxide + 0.1 mol/L sucrose, 0.25 mol/L dimethyl sulfoxJde + 0.1 mol/L sucrose and 0.1 mol/L sucrose. The frozen-thawed and fresh controlled human ovarian tissues were cultured in vitro. The expression of VEGF and CD34, as well as microvessel density, was analyzed by immunohistochemistry. RESULTS AND CONCLUSION: There was patchy and mild expression of VEGF in the stromal cells of all the three groups before and after culture. The expression of VEGF increased and reached peak value after culture for 2 days, began to decrease after culture for 4 days and further attenuated after culture for 6 days in all the three groups. Compared with slow-freezing group, the expression of VEGF in NIV group was closer to that in fresh control group. Microvessel density of all the three groups increased and reached peak value after culture for 2 days, and the microvessel density of fresh control group and NIV group was significantly higher than that of slow-freezing group (P < 0.05). The microvessel density of slow-freezing group after culture for 4 days and that of all the three groups after culture for 6 days significantly decreased compared with after culture for 2 days (P <0.05). NIV is superior to slow-freezing to preserve stromal cells and extracellular matrix of human ovarian tissue, and plays less influence in VEGF expression and angiogenesis in human ovarian tissue.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.

Prostate cancer in patients with dwarfism is rarely reported. One case was reported in this article. The patient was admitted to the hospital due to the PSA elevation for more than 4 years. Due to the dwarf disease, the patient could not accommodate the transrectal ultrasound probe, and was highly suspected of prostate cancer.The prostate needle biopsy was not performed. Combined with the medical history, PSA level, preoperative MRI and PSMA-PET/CT examination, the patient was clinically diagnosed with localized prostate cancer, and radical surgical treatment was performed.
