Horseshoe kidney and retrocaval ureter are uncommon congenital anomalies of the genitourinary system that are easily diagnosed by typical imaging features. Both anomalies presenting in one patient is a rare disease characterized by isthmus of horseshoe kidney between the abdominal aorta and inferior vena cava. The clinical diagnosis and treatment of horseshoe kidney with retrocaval ureter remain a challenge. Here, we reported a case of a 44-year-old man with the two anomalies who was preoperatively diagnosed by unenhanced computed tomography scanning immediately after retrograde pyelography. The literatures on such combined anomalies are reviewed and the diagnostic evaluation and surgical management of this rare entity are discussed.

Background Docetaxel （DOC） therapy is well tolerated and shows high response rates in patients with hormone refractory prostate cancer （HRPC）. There are many reports on the effect of rapamycin （RPM） on the treatment of carcinogenesis. The goal of this study was to test whether RPM could enhance the susceptibility of both androgen-dependent and -independent prostate carcinoma cells to DOC. Methods Prostate cancer （PC） cell lines （LNCap, PC3 and AILNCap） were cultured and treated with RPM and DOC alone or in combination. The effects of therapeutic agents on cells were determined by the WST-1 assay. Apoptosis induction was confirmed by flow cytometric analysis. The apopcyto caspase colorimetric assay kit was applied to measure the activities of caspases 3 and 9. The antitumor effects of RPM and DOC against PC cells were also assessed in nude mice using four randomized groups： control, RPM, DOC and combination drug therapy by measuring tumor size. All the animals tolerated both RPM and DOC without significant weight loss. Results RPM and DOC caused dosage-dependent growth suppression of PC cells. RPM could increase the susceptibility of PC cells to DOC significantly, and combined treatment with RPM and DOC caused synergistic growth suppression in all examined PC cell lines by isobolographic analysis. Both RPM and DOC significantly induced apoptosis in a dosage-dependent manner. RPM （10 nmol/L）, DOC （1 nmol/L）, and combined treatment induced apoptosis rate were 8%, 17% and 38%, respectively （the control was 2%）. RPM could promote the apoptosis induced by DOC in PC cell lines. Both RPM and DOC significantly increased the caspase activity in a dosage-dependent manner. The relative activities of caspase 9 in control, RPM, DOC and RPM＋DOC groups were 0.22±0.02, 0.36±0.06, 0.47±0.05 and 0.84±0.08, respectively. The relative activities of caspase 3 were 0.21±0.02, 0.24±0.05, 0.42±0.06 and 0.81±0.09, respectively. Either RPM or DOC alone significantly inhibited the growth of PC

史达祖(梅溪)是南宋中后期著名词人,其咏物词历来享有盛誉。解读史达祖全部咏物词可以发现,其咏物词以体物为主,与柳永、苏轼相近,而与周邦彦、姜夔貌同实异。从内容来看,其大多数咏物词没有太深刻的寄托,只有部分作品寄寓了较深刻的情志内涵,少数作品则具有富于理趣的特点。给梅溪咏物词带来声誉的是其“凝情观物式”的创作姿态及其精湛圆熟的表现技法。

Background Renal transplants can improve the quality of life for recipients, but the quality of their sexual life might not be improved. This study was conducted to research the prevalence of erectile dysfunction （ED） and the influential factors in male renal transplant recipients （RTRs）. Methods A cross-sectional survey was conducted in three renal transplantation centers. Structured questionnaires were administrated by trained interviewers to 824 male renal transplant patients, who had active sexual lives in the last 6 months. Results Complaints of ED were reported by 75.5% of the 809 RTRs （age range 19-75 years, mean age （45±10） years）, whose questionnaires were completed. Mild, moderate and severe ED were reported at 53.6%, 8.3% and 13.6%, respectively. The mean age and the graft duration were significantly higher in male RTRs with ED compared to potent graft recipients （P=-0.00 and 0.04, respectively）. The prevalence of ED increased with the increase in age. It was 60.7%, 65.8%, 75.2%, 87.5% and 92.2% in patients with age below 30 years, 31-40 years, 41-50 years, 51-60 years and over 60 years, respectively （P=-0.000）. Moreover, the severity of ED increased with aging. The percentage of moderate and severe cases of ED increased from 6.7% in patients below 40 years to 28.9% in those over 40 years （P=-0.000）. The prevalence of ED in the RTR who had no occupation was higher than in those who were holding a position （P=-0.001）. The prevalence of ED decreased with the increase in the education level. The prevalence of ED was 94.3%, 86.4%, 74.0% and 67.8% in men with elementary school or lower, middle school, high school, and college or higher degrees, respectively （P=0.000）. Patients, whose distal end of arteria iliaca interna was interrupted and underwent iterative transplantation, worried transplanted kidney function was impacted by sexual life, and received cyclosporine （CsA）-based immunosuppressive regimens, were more likely to have ED （P=-0.000, 0.001, 0.000, 0.

在返乡创业潮的背景下,"何种农民创新创业教育模式更为有效"成为时下的热点命题。农民创新创业教育模式可以分为政府主导、社会民办等类型。然而,现实中政府主导模式存在服务项目单一、缺乏创新与竞争意识等困境,社会民办模式存在教育意识与社会责任感不强的问题。那么,由符合教育主体资格的农民自主地提供创新创业教育服务,可以成为农民创新创业教育的新模式,进一步实现农民职业的多元转型目标。

平泉别业是李德裕在洛阳经营数十年而成的私家园林,也是在中国园林史上产生过较大影响的洛阳名园。平泉别业的声名远播,既与园林规模、园中奇花异石相关,也与李德裕创作的大量平泉诗有关。由于宦途奔波,李德裕很少入住平泉别业,他通过回忆、想象和书写,构建了具有桃源特质的园林世界,从而达到心灵的自适。为了弥补园林生活的缺失,李德裕命其子孙保守平泉别业中的一草一木,这一行为在明清时期遭到了许多批评,成为中国园林史上的热点话题。实际上,李德裕的守园观一方面与其对园林的喜爱之情有关;另一方面,也不能排除其维持家族政治地位这一心理因素的影响。李德裕是中晚唐政坛的风云人物,他的园林实践、园林观念以及园林书写对后人产生了很大影响。

研究逆变器波形控制技术的问题,传统PI控制存在明显的缺点,导致输出电压质量不佳。为了提高逆变器输出电压的稳态和动态性能,提出了一种新的分数阶PI控制策略。分数阶PI控制器比PI控制器多了一个可调参数λ,使设计更加灵活,性能更加优越。仿真结果显示,分数阶PI控制策略提高了逆变器输出电压的稳态精度,增强了负载抗干扰能力,系统获得较快的动态响应,改进控制策略对于中小型风力发电系统并网逆变器的实际应用具有重要圣者价值。
