Objective: Prostate cancers(PCa) in Asian individuals are molecularly distinct from those found in their Caucasian *** is no risk stratification tool for Asian men with rapid biochemical recurrence(BCR) following radical prostatectomy(Rad P). This study aims to assess the detection rate of ^(68)Ga-prostate-specific membrane antigen-positron emission tomography/computed tomography(PSMA-PET/CT) for diagnosis of clinical recurrence and as a treatment decision making tool in Asian patients with BCR post-Rad ***: ^(68)Ga PSMA-PET and CT body with/without bone scan [conventional workup(CWU)] were performed in 55 Asian patients with BCR within 36 months post-Rad P. Two blinded reviewers assessed the images. Detection rates of ^(68)Ga PSMAPET/CT were evaluated, and impact on management was reviewed by comparison with ***: Median time to BCR post-Rad P was 8.1 months. Detection rate for ^(68)Ga PSMA-PET/CT was 80%(44/55). A positive scan was significantly associated with increasing prostate-specific antigen(PSA) level [odds ratio(OR) = 1.13(95% CI 1.05–1.30), P =0.017], but not with higher Gleason grade or shorter PSA doubling time. Compared to CWU, ^(68)Ga PSMA-PET/CT detected an additional 106 lesions in 33/44 patients with a positive scan, resulting in a change in management in 25/44(56.8%) patients: 10 to hormonal therapy(HT) and whole pelvis radiotherapy(RT) in addition to bed RT, and 15 to palliative HT ***: In the present report, we demonstrated the diagnostic and treatment decision utility of ^(68)Ga PSMA-PET/CT in Asian men with rapid BCR. Detection of small volume nodal and systemic recurrences at low PSA levels(< 1.0 ng/mL) highlights the role of the tool in assigning patients to treatment intensification with HT-RT or palliative HT in polymetastatic disease.

Objective:To scrutinize the definitions of minimal invasive surgical therapy(MIST)and to investigate urologists’knowledge,attitudes,and practices for benign prostatic obstruction ***:A 36-item survey was developed with a Delphi *** on definitions of MIST and attitudes and practices of benign prostatic obstruction surgeries were *** were invited globally to complete the online *** was achieved when more than or equal to 70%responses were“agree or strongly agree”and less than or equal to 15%responses were“disagree or strongly disagree”(consensus agree),or when more than or equal to 70%responses were“disagree or strongly disagree”and less than or equal to 15%responses were“agree or strongly agree”(consensus disagree).Results:The top three qualities for defining MIST were minimal blood loss(n=466,80.3%),fast post-operative recovery(n=431,74.3%),and short hospital stay(n=425,73.3%).The top three surgeries that were regarded as MIST were Urolift®(n=361,62.2%),Rezum®(n=351,60.5%),and endoscopic enucleation of the prostate(EEP)(n=332,57.2%).Consensus in the knowledge section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,day surgery feasibility,and post-operative *** in the attitudes section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,and day surgery *** on both sections was achieved for EEP as the option with the better symptoms and flow improvement,lower retreatment rate,and better suitable for prostate more than 80 ***:Minimal blood loss,fast post-operative recovery,and short hospital stay were the most important qualities for defining ***®,Rezum®,and EEP were regarded as MIST by most urologists.

利用PCR、克隆测序、序列拼接获得山羊(Capra hircus)BMP15基因全长。利用F-CSGE技术分析两个外显子,发现山羊BMP15编码序列的第901处发生了A→G单碱基突变,该突变使得第301位氨基酸(成熟蛋白质第32位氨基酸)由丝氨酸变为甘氨酸。利用LDR技术对济宁青山羊、鲁北白山羊和沂蒙黑山羊进行突变检测,并进行其与产羔数的关联分析。结果表明,该突变对济宁青山羊产羔数没有显著影响,但对鲁北白山羊及沂蒙黑山羊产羔数均有显著影响(P<0.05)。GG型和AG型的鲁北白山羊产羔数分别比AA型多0.34只(P<0.01)和0.31只(P<0.01)。AG型沂蒙黑山羊的产羔数比AA型多0.13只(P<0.01)。初步表明,BMP15是控制鲁北白山羊和沂蒙黑山羊多胎性状的一个主效基因或是与之存在紧密遗传连锁的分子标记。
