Proteases and their inhibitors as prognostic factors for high-grade serous ovarian cancer

Ovarian carcinoma is one of the most lethal malignancies, but only very few prognostic biomarkers are known. The degradome, comprising proteases, protease non-proteolytic homologues and inhibitors, have been involved in the prognosis of many cancer types, including ovarian carcinoma. The prognostic significance of the whole degradome family has not been specifically studied in high-grade serous ovarian cancer. A targeted DNA microarray known as the CLIP-CHIP microarray was used to identify potential prognostic factors in ten high-grade serous ovarian cancer women who had early recurrence (<1.6 years) or late/no recurrence after first line surgery and chemotherapy. In women with early recurrence, we identified seven upregulated genes (TMPRSS4, MASP1/3, SPC18, PSMB1, IGFBP2, CFI – encoding Complement Factor I – and MMP9) and one down-regulated gene (ADAM-10). Using immunohistochemistry, we evaluated the prognostic effect of these 8 candidate genes in an independent cohort of 112 high-grade serous ovarian cancer women. Outcomes were progression, defined according to CA-125 criteria, and death. Multivariate Cox proportional hazard regression models were done to estimate the associations between each protein and each outcome. High ADAM-10 expression (intensity of 2–3) was associated with a lower risk of progression (adjusted hazard ratio (HR): 0.51; 95% confidence interval (CI): 0.29-0.87). High complement factor I expression (intensity 2–3) was associated with a higher risk of progression (adjusted HR: 2.30, 95% CI: 1.17–4.53) and death (adjusted HR: 3.42; 95% CI: 1.72–6.79). Overall, we identified the prognostic value of two proteases, ADAM-10 and complement factor I, for high-grade serous ovarian cancer which could have clinical significance.     

全身运动质量评估指导高危儿早期干预的研究

目的 通过比较全身运动(GMs)评估正常的高危儿单纯家庭康复训练与家庭康复训练联合药物干预的预后,分析GMs对高危儿早期干预的指导意义。方法 选取2016年2月-2017年2月于潍坊市妇幼保健院康复科就诊并接受GMs评估正常的183例高危儿,随机分组为观察组和对照组,观察组为单纯家庭康复训练组89例,对照组为家庭康复训练联合药物干预组94例。采用Peabody运动发育量表对两组患儿分别于纠正月龄6、9、12个月龄进行评估,对Peabody运动发育量表中各指标应用SPSS 21.0进行统计分析。结果 干预后,纠正月龄6、9、12个月龄时,观察组和对照组Peabody运动发育量表中粗大运动商(GMQ)、精细运动商(FMQ)、总运动商(TMQ)比较,差异无统计学意义(P>0.05),重复测量方差分析发现观察组和对照组的GMQ、FMQ、TMQ评分的组间效应差异无统计学意义(P>0.05),时间效应差异有统计学意义(P<0.05),干预因素与时间因素不存在交互作用(P>0.05)。结论 GMs评估对高危儿早期干预具有指导意义。GMs评估正常者,家庭康复训练可达到促进高危儿运动功能发育的目的 ,避免仅因系高危儿而采取“过度干预”。

平顶山市8岁学龄儿童患龋状况及影响因素分析

目的 了解平顶山市8岁学龄儿童龋病流行状况,探讨影响龋病发生发展的危险因素。 方法 参考“第三次全国口腔健康调查”的标准,采用分层整群抽样的方法,对1 762名适龄儿童进行口腔检查和问卷调查。 结果 平顶山市8岁学龄儿童患龋率84.68%,龋均4.79,城乡结合区域及农村儿童患龋率和龋均明显高于城市,差异有统计学意义(P＜0.05);乳、恒牙患龋率分别为83.65%、25.77%;城乡类型(OR=22.42)、家庭收入(OR=10.21)、睡前是否有吃零食习惯(OR=8.01)、吃完零食是否刷牙(OR=6.00)、进食甜食频率(OR=8.28)、刷牙方法(OR=8.88)、家长是否检查刷牙效果(OR=9.15)是影响患龋率的因素。 结论 平顶山市农村及城乡结合区域儿童患龋率较高,应加强口腔健康教育和龋病预防控制工作。     

Constructing queer mother‐knowledge and negotiating medical authority in online lesbian pregnancy journals

Medical interactions around reproduction are increasingly extending beyond the physician's office and onto the Internet, where negotiation with medical authority occurs in complex and dynamic ways. Recently, scholars have noted the Internet's potential for creating spaces where women can dialogue with and reconstruct medical authority, yet this growing body of work is overwhelming heteronormative. This paper thus interrogates how lesbian women use the Internet to challenge, deploy, and rework medical authority around reproduction while navigating the transition to parenthood. I draw from 17 online journals authored by lesbian couples during the conception, pregnancy, and birth of their first child, each spanning between 18 months and 2 years, in order to understand how the transition process unfolds over time. I argue that lesbian couples engage with medical authority when seeking affirmation and normalisation yet discard and publicly reject the heteronormative assumptions that accompany reproductive medicine. Further, they chart a new process that I term ‘constructing queer mother‐knowledge’, in which they critique and balance knowledges from institutionalised medicine, their own bodies, and their queer communities. With this new concept, I complicate understandings of lesbian mothers‐to‐be and their interactions with medical authority as they build subversive families.
