Transmission of Grapevine Red Blotch Virus by Spissistilus festinus [Say, 1830] (Hemiptera: Membracidae) between Free-Living Vines and Vitis vinifera ‘Cabernet Franc’

Grapevine red blotch disease emerged within the past decade, disrupting North American vine stock production and vineyard profitability. Our understanding of how grapevine red blotch virus (GRBV), the causal agent of the disease, interacts with its Vitis hosts and insect vector, Spissistilus festinus, is limited. Here, we studied the capabilities of S. festinus to transmit GRBV from and to free-living vines, identified as first-generation hybrids of V. californica and V. vinifera ‘Sauvignon blanc’ (Vcal hybrids), and to and from V. vinifera ‘Cabernet franc’ (Vvin Cf) vines. The transmission rate of GRBV was high from infected Vcal hybrid vines to healthy Vcal hybrid vines (77%, 10 of 13) and from infected Vvin Cf vines to healthy Vcal hybrid vines (100%, 3 of 3). In contrast, the transmission rate of GRBV was low from infected Vcal hybrid vines to healthy Vvin Cf vines (15%, 2 of 13), and from infected Vvin Cf vines to healthy Vvin Cf vines (19%, 5 of 27). No association was found between transmission rates and GRBV titer in donor vines used in transmission assays, but the virus titer was higher in the recipient leaves of Vcal hybrid vines compared with recipient leaves of Vvin Cf vines. The transmission of GRBV from infected Vcal hybrid vines was also determined to be trans-stadial. Altogether, our findings revealed that free-living vines can be a source for the GRBV inoculum that is transmissible by S. festinus to other free-living vines and a wine grape cultivar, illustrating the interconnected roles of the two virus hosts in riparian areas and commercial vineyards, respectively, for virus spread. These new insights into red blotch disease epidemiology will inform the implementation of disease management strategies.     

老年子宫颈癌患者生存情况及其影响因素分析

目的:探讨影响老年子宫颈癌患者术后生存的影响因素.方法:对1980年1月～1998年12月诊治的老年子宫颈癌243例临床资料和随访结果进行回顾性分析.采用Kaplan-Meier法计算累积生存率,用Log-Rank法比较各因素不同水平生存分布的差异,进一步应用COX回归模型进行预后因素分析.结果:全组子宫颈癌术后5、10、15年累积生存率分别为87％、81％、75％,Log-Rank分析结果显示不同临床分期、不同组织分化程度、有无淋巴结转移、不同治疗方法患者生存差异存在明显差异(x2=23.172,P＜0.05;x2=32.766,P＜0.05;x2 =25.086,P＜0.05;x2 =28.906,P＜0.05).年龄、不同生长方式、肿瘤直径、有无辅助治疗水平间生存差异无统计学意义(P＞0.05),COX模型多因素分析表明:临床分期、组织分化程度、淋巴结转移是影响预后的独立因素(P＜0.01).结论:临床分期、淋巴结转移、组织分化是影响老年子宫颈癌预后的独立危险因素,及早发现和合理降低临床分期是治疗老年子宫颈癌以及提高预后的关键手段.     

子宫内膜微创技术对体外受精和胚胎移植妊娠结局影响的研究

目的探讨子宫内膜微创术对不孕症妇女体外受精-胚胎移植(IVF-ET)妊娠结局的影响。方法选择2010年1月-2012年6月在新疆医科大学第一附属医院生殖助孕中心74例接受IVF-ET/卵胞浆内单精子注射(ICSI)的不孕症患者,以采用子宫内膜微创术的41例患者作为治疗组,在促排周期月经来潮24h内进行子宫内膜微创术;以未进行子宫内膜微创术的33例为对照组,比较两组的胚胎种植率及临床妊娠率。结果治疗组与对照组胚胎种值率分别26.51%和11.43%,差异有统计学意义(P<0.05);治疗组与对照组临床妊娠率分别为43.90%和21.21%,差异有统计学意义(P<0.05)。结论不孕症妇女进行子宫内膜微创术后能够显著提高IVF-ET/ICSI周期的胚胎种植率及临床妊娠率,改善妊娠结局。     

米非司酮对不同月经周期异位和在位子宫内膜雌激素受体α和孕激素受体表达的影响

目的 探讨米非司酮对雌激素受体α(ERα)和孕激素受体(PR)在不同月经周期的子宫腺肌症中表达的影响.方法 47例行全子宫切除术的子宫腺肌症患者分为米非司酮组(n=24)和未用药组(n=23);无腺肌症的正常子宫内膜作为对照组(n=15).运用免疫组化的方法测定异位和在位子宫内膜及正常子宫内膜在不同月经周期的腺上皮及间质细胞中ERα和PR水平.结果 未用药组ERα和PR在异位子宫内膜腺上皮及间质细胞中的表达均低于在位内膜及对照组正常内膜(P<0.05).对照组及未用药组ERα和PR在在位内膜腺上皮细胞中的表达,增生期高于分泌期(P<0.05),而在未用药组异位内膜,差异无统计学意义(P>0.05).ERα和PR在异位和在位子宫内膜中的表达,米非司酮组低于未用药组(P<0.05).结论 ERα和PR在异位子宫内膜中的表达与在位子宫内膜不同;异位内膜丧失了正常内膜的周期性变化规律;米非司酮通过下调其性激素受体(ERα和PR)含量治疗子宫腺肌症.     

Coexistence of benign phyllodes tumor and invasive ductal carcinoma in distinct breasts: case report

This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.
