To date, many techniques have been reported for vaginoplasty in male-to-female trans-sexual (MTFTS) patients, such as the use of a rectum transfer, a penile-scrotal flap and a reversed penile flap. However, none of these procedures is without its disadvantages. We developed a newly kind of flap for vaginoplasty, the M-shaped perineo-scrotal flap (M-shaped flap), using skin from both sides of the scrotum, shorn of hair by preoperative laser treatment. We applied this new type of flap in 7 MTFTS patients between January 2006 and January 2007. None of the flaps developed necrosis, and the patients could engage in sexual activity within 3 months of the operation. The M-shaped flap has numerous advantages: it can be elevated safely while retaining good vascularity, it provides for the construction of a sufficient deep vagina without a skin graft, the size of the flap is not influenced entirely by the length of the penis, and it utilizes skin from both sides of the scrotal area, which is usually excised.

抄録 Although graft survival following renal transplantation (RTx) has improved, outcomes following highrisk RTx are variable. Preexisting antibodies, including donor-specific antibodies (DSA), play an important role in graft dysfunction and survival. We have designed a study to investigate the safety and efficacy of anti-CD20 monoclonal antibodies (rituximab) in high-risk RTx recipients. Major eligibility criteria include: 1) major and minor ABO blood group mismatch, 2) positive DSA. Thirty-five patients will receive 200 mg/body of rituximab. The primary endpoint is the incidence of B cell depletion. This study will clarify whether rituximab is efficacious in improving graft survival in high-risk RTx recipients.

From September 2003 to December 2005, 188 patients who visited our hospital and allied institutions for the purpose of prostate brachytherapy were administrated hormonal therapy for volume reductions before brachytherapy. The pretreatment and posttreatment of prostate volume using a transrectal ultrasound volumetric study and the types and duration of hormonal therapy were analyzed. We administered 91 patients with Luteinizing hormone-releasing hormone (LH-RH) agonist, 49 patients with anti-androgen (bicaltamide/flutamide), and 48 patients with maximum androgen blockade (MAB). The duration of the hormonal therapy was 1-3 months for 49 patients, 4-6 months for 59 patients, 7-9 months for 40 patients, 10-12 months for 32 patients, and over 13 months for 8 patients. Before the initiation of hormonal therapy, the mean prostate volume was 35.12 ml (11.04-78.71 ml), and the average of prostate volume before and after hormonal therapy was 36.79 ml and 24.79 ml, respectively (a 32.4% reduction). The prostate volume reduction rate was 32.0% for the LH-RH agonist only, 18.1% for the anti-androgen only and 41.2% for the MAB. No statistically significant difference was observed for the duration of hormonal therapy between 3 groups. A three-month course of the neoadjuvant LH-RH agonist indicated a sufficient volume reduction effectiveness for a large prostate volume.

抄録 The cluster of differentiation 147 (CD147), also known as EMMPRIN, is a key molecule that promotes cancer progression. We previously developed an adenoviral vector encoding a tumor suppressor REIC/Dkk-3 gene (Ad-REIC) for cancer gene therapy. The therapeutic effects are based on suppressing the growth of cancer cells, but, the underlying molecular mechanism has not been fully clarified. To elucidate this mechanism, we investigated the effects of Ad-REIC on the expression of CD147 in LNCaP prostate cancer cells. Western blotting revealed that the expression of CD147 was significantly suppressed by Ad-REIC. Ad-REIC also suppressed the cell growth of LNCaP cells. Since other researchers have demonstrated that phosphorylated mitogen-activated protein kinases (MAPKs) and c-Myc protein positively regulate the expression of CD147, we investigated the correlation between the CD147 level and the activation of MAPK and c-Myc expression. Unexpectedly, no positive correlation was observed between CD147 and its possible regulators, suggesting that another signaling pathway was involved in the downregulation of CD147. This is the first study to show the downregulation of CD147 by Ad-REIC in prostate cancer cells. At least some of the therapeutic effects of Ad-REIC may be due to the downregulation of the cancer-progression factor, CD147.

抄録 Human RAD17, as an agonist of checkpoint signaling, plays an essential role in mediating DNA damage. This hospital-based case-control study aimed to explore the association between RAD17 rs1045051, a missense sin-gle nucleotide polymorphism (SNP), and prostate cancer risk. Subjects were 358 prostate cancer patients and 314 cancer-free urology patients undergoing treatment at the Zhujiang Hospital of Southern Medical University in China. RAD17 gene polymorphism rs1045051 was evaluated by the SNaPshot method. Compared with the RAD17 gene polymorphism rs1045051 AA genotype, there was a higher risk of prostate cancer for the CC gen-otype (adjusted odds ratio [AOR] = 1.731, 95% confidence interval [95%CI] = 1.031−2.908, p = 0.038). Compared with the A allele, the C allele was significantly associated with the disease status (AOR = 1.302, 95%CI = 1.037−1.634, p = 0.023). All these findings indicate that in the SNP rs1045051, both the CC genotype and C allele may have a substantial influence on the prostate cancer risk.

The purpose of this study is to compare the performance of laparoscopic partial nephrectomy (LPN) with and without clamping of the renal artery and to evaluate the impact of clamping on postoperative renal function. A total of 20 patients underwent LPN, 13 without and 7 with clamping of the renal artery. The 2 groups were compared with respect to complications, blood loss, operative time, mean tumor size, and incidence of positive margins. Renal function was evaluated by pre- and postoperative renal scintigraphy using 99mTechnetium-mercaptoacetyltriglycine (99mTc-MAG3). Intraoperative blood loss was significantly higher in the group without clamping than in the group with clamping (p0.04). In the group with clamping, the median warm ischemic time was 35min (range 25-40min). The serum creatinine values and the renal scintigraphy showed no influence on postoperative renal function with or without clamping. In the group without clamping, 2 cases were showed positive surgical margins. The procedure performed with clamping of the renal artery is superior to the procedure performed without clamping as it provides the advantages of controlling hemorrhaging without injury to renal function and prolonging the surgical time and allowing for more accurate resection of renal tumors.

抄録 Optimal neoadjuvant hormone therapy (NHT) for reducing prostate cancer (PC) patients’ prostate volume pre-brachytherapy is controversial. We evaluated the differential impact of neoadjuvant gonadotropin-releasing hormone (GnRH) antagonist versus agonist on post-brachytherapy testosterone recovery in 112 patients treated pre-brachytherapy with NHT (GnRH antagonist, n=32; GnRH agonists, n=80) (Jan. 2007-June 2019). We assessed the effects of patient characteristics and a GnRH analogue on testosterone recovery with logistic regression and a propensity score analysis (PSA). There was no significant difference in the rate of testosterone recovery to normal levels (> 300 ng/dL) between the GnRH antagonist and agonists (p=0.07). The GnRH agonists induced a significantly more rapid testosterone recovery rate at 3 months post-brachytherapy versus the GnRH antagonist (p<0.0001); there was no difference in testosterone recovery at 12 months between the GnRH antagonist/agonists (p=0.8). In the multivariate analysis, no actor was associated with testosterone recovery. In the PSA, older age and higher body mass index (BMI) were significantly associated with longer testosterone recovery. Post-brachytherapy testosterone recovery was quicker with the neoadjuvant GnRH agonists than the antagonist, and the testosterone recovery rate was significantly associated with older age and higher BMI. Long-term follow-ups are needed to determine any differential effects of GnRH analogues on the quality of life of brachytherapy-treated PC patients.

抄録 Deficiencies in the human DNA repair gene WRN are the cause of Werner syndrome, a rare autosomal recessive disorder characterized by premature aging and a predisposition to cancer. This study evaluated the association of WRN Leu1074Phe (rs1801195), a common missense single nucleotide polymorphism in WRN, with prostate cancer susceptibility in Chinese subjects. One hundred and forty-seven prostate cancer patients and 111 male cancer-free control subjects from 3 university hospitals in China were included. Blood samples were obtained from each subject, and the single nucleotide polymorphism WRN Leu1074Phe was genotyped by using a Snapshot assay. The results showed that WRN Leu1074Phe was associated with the risk of prostate cancer in Chinese men and that the TG/GG genotype displayed a decreased prevalence of prostate cancer compared with the TT genotype (OR=0.58, 95%CI:0.35-0.97, p=0.039). Through stratified analysis, more significant associations were revealed for the TG/GG genotype in the subgroup with diagnosis age <_ 72 yr (OR=0.27, 95%CI:0.12-0.61, p=0.002) and in patients with localized diseases (OR=0.36, 95%CI:0.19-0.70, p=0.003). However, no statistically significant difference was found in the subgroup with age >72 yr or in patients with advanced diseases. We concluded that the genetic variant Leu1074Phe in the DNA repair gene WRN might play a role in the risk of prostate cancer in Chinese subjects.
