行政问责制的法制构建

河北法学 2010年第9期28卷 96-102页

作者：高红艳玉林师范学院广西玉林537000

行政问责制是政府官员向社会公众和民意机关承担政治责任的一种政治法律制度。我国现行的行政问责制存在问责事由狭窄、对象不清、主体越位与缺位并存,责任不明、落实不力和程序不规范等问题。为此,我们需要明确行政问责制的要素构造与... 详细信息

行政问责制是政府官员向社会公众和民意机关承担政治责任的一种政治法律制度。我国现行的行政问责制存在问责事由狭窄、对象不清、主体越位与缺位并存,责任不明、落实不力和程序不规范等问题。为此,我们需要明确行政问责制的要素构造与运行机制,加强人大的问责职能,完善政府绩效评估、行政公开、新闻监督等配套制度,同时要壮大第三部门,强化社会监督。

Background Extracellular vesicles(EVs) present in oviductal(OF) and uterine fluid(UF) have been shown to enhance bovine embryo quality during in vitro culture by reducing lipid contents and modulating lipid metabolism-related genes(LMGs), while also influencing cell proliferation, suggesting their involvement on the regulation of different biological pathways. The regulation of signaling pathways related to cell differentiation, proliferation, and metabo-lism is crucial for early embryo development and can determine the success or failure of the pregnancy. Bioactive molecules within EVs in maternal reproductive fluids, such as micro RNAs(miRNAs), may contribute to this regulatory process as they modulate gene expression through post-transcriptional *** This study evaluated miRNA cargo in OF-EVs from the early luteal phase and UF-EVs from the mid-luteal phase, coinciding with embryo transit within oviduct and uterus in vivo, and its possible influence on LMGs and sign-aling pathways crucial for early embryo development. A total of 333 miRNAs were detected, with 11 exclusive to OF, 59 to UF, and 263 were common between both groups. From the 20 differentially expressed miRNAs, 19 up-regulated in UF-EVs(bta-miR-134, bta-miR-151-3p, bta-miR-155, bta-miR-188, bta-miR-181b, bta-miR-181d, bta-miR-224, bta-miR-23b-3p, bta-miR-24-3p, bta-miR-27a-3p, bta-miR-29a, bta-miR-324, bta-miR-326, bta-miR-345-3p, bta-miR-410, bta-miR-652, bta-miR-677, bta-miR-873 and bta-miR-708) and one(bta-miR-148b) in OF-EVs. These miRNAs were predicted to modulate several pathways such as Wnt, Hippo, MAPK, and lipid metabolism and degradation. Differ-ences in miRNAs found in OF-EVs from the early luteal phase and UF-EVs from mid-luteal phase may reflect differ-ent environments to meet the changing needs of the embryo. Additionally, miRNAs may be involved, particularly in the uterus, in the regulation of embryo lipid metabolism, immune system, and *** Our study su

目的基于血液筛查核酸检测反应性献血者的HBV感染的确认,探讨核酸检测反应性献血者的归队策略。方法联合应用自建的高灵敏度核酸检测体系、血液核酸筛查等多种核酸检测(NAT)方法,并结合血清学检测、献血者随访,对核酸检测反应性(NAT-yield)献血者中的HBV感染进行确认和感染状态识别。依据确认的HBV感染血浆样本,比较不同确认方法、确认指标或指标组合对HBV感染确认的效果。结果2010年11月—2021年2月,在血液筛查检出的876位NAT-yield献血者中共确认HBV感染者511人(OBI 451人,急性早期HBV感染者27人,不能确认感染者33人,无感染者30人,不能确认HBV感染者335人)。采用单检系统对混检系统检出的HBV感染血浆进行复测的检出率为96.6%,明显高于混检系统对单检系统检出的HBV DNA反应性(HBV DNA R)组和鉴别试验无反应性(NDR)组的复测检出率(76.4%和55.7%)(P0.05)。NDR样本在模式2(ID×5+鉴别×2)下复测检出率(65.2%)高于模式1(ID×2+鉴别×1)(39.2%)(P0.05);2种单检复测模式下的HBV DNA R样本复测检出率无明显差异(P>0.05),但均明显高于NDR样本(P0.05)。回溯OBI献血者既往NAT数据,有46%经历多次NAT检测而未能检出。有59.1%OBI献血者随访检不出HBV DNA。OBI献血者中抗-HBc+占比为90.2%,单独抗-HBc+为49.2%,远高于不能确认感染组(P0.05);HBeAg、抗-HBe和抗-HBc IgM在OBI和不能确认感染组中的比例极低且无差异(P>0.05)。结论近60%的NAT-yield献血者可以确认HBV感染。为保证献血者归队的安全性,需要更高灵敏度的HBV DNA确证技术提高HBV感染的确认率。抗-HBc是NAT-yield献血者OBI风险排查和归队评估最重要的血清学指标。

Introduction: Uterine leiomyomas, or fibroids, are prevalent benign tumors affecting up to 70% of reproductive-age women in the United States, significantly impacting productivity and quality of life. Despite their commonality, the epidemiology and clinical patterns of leiomyomas in Puerto Rico remain inadequately researched. Methods: This study conducted a secondary data analysis using clinical, menstrual cycle characteristics, and demographic data from self-administered questionnaires of women undergoing diagnostic laparoscopy for endometriosis in Puerto Rico. Chi-square tests and t-tests analyzed categorical and continuous variables, respectively (p Results: Among 1,610 endometriosis cases, 312 included uterine fibroids. Prevalence estimates were 10.3% (40 years). Primiparous women averaged 22.14 years, with 40.71% having 2 - 3 pregnancies and 26.28% experiencing miscarriages. Symptoms included infertility (29.5%), dyspareunia (40.7%), severe pain (50%), and dysmenorrhea (75.6%). Comorbidities included ovarian cysts (52.2%) and abnormal uterine bleeding (37.8%). Conclusions: Advanced age, parity, and comorbidities like diabetes and hypertension were prevalent in our cohort. Understanding the epidemiological profile of women living in Puerto Rico with uterine fibroids is crucial for improving diagnostic awareness and enhancing patient care.
