Background: Cavernous transformation of the portal vein(CTPV) due to portal vein obstruction is a rare vascular anomaly defined as the formation of multiple collateral vessels in the hepatic hilum. This study aimed to investigate the imaging features of intrahepatic portal vein in adult patients with CTPV and establish the relationship between the manifestations of intrahepatic portal vein and the progression of CTPV. Methods: We retrospectively analyzed 14 CTPV patients in Beijing Tsinghua Changgung Hospital. All patients underwent both direct portal venography(DPV) and computed tomography angiography(CTA) to reveal the manifestations of the portal venous system. The vessels measured included the left portal vein(LPV), right portal vein(RPV), main portal vein(MPV) and the portal vein bifurcation(PVB). Results: Nine males and 5 females, with a median age of 40.5 years, were included in the study. No significant difference was found in the diameters of the LPV or RPV measured by DPV and CTA. The visualization in terms of LPV, RPV and PVB measured by DPV was higher than that by CTA. There was a significant association between LPV/RPV and PVB/MPV in term of visibility revealed with DPV( P = 0.01), while this association was not observed with CTA. According to the imaging features of the portal vein measured by DPV, CTPV was classified into three categories to facilitate the diagnosis and treatment. Conclusions: DPV was more accurate than CTA for revealing the course of the intrahepatic portal vein in patients with CTPV. The classification of CTPV, that originated from the imaging features of the portal vein revealed by DPV, may provide a new perspective for the diagnosis and treatment of CTPV.

The BL07U beamline is a new extreme ultraviolet and soft X-ray beamline housed in the Shanghai Synchrotron Radiation Facility. Beamlines are used in nano-resolved angle-resolved photoemission spectroscopy(nano-ARPES), spin-resolved angle-resolved photoemission spectroscopy(spin-ARPES), X-ray magnetic circular dichroism spectroscopy, and X-ray magnetic linear dichroism spectroscopy for certain scientific research. The BL07U beamline, which is based on a pair of elliptical polarized undulators and a variable-included-angle plane-grating monochromator, delivers circularly or linear polarized X-rays within the energy range of 50–2000 eV. The beamline features two branches: One dedicated to nano-ARPES,which has a minimum spot size of only ~ 200 nm, and another branch comprising spin-ARPES, a vector magnetic field, and superconductive magnetic end-station.

基于查明案件事实、降低诉讼成本、避免矛盾裁判等诉讼政策,我国确立了程序导向的必要共同诉讼,导致必要共同诉讼的泛用和“同案不同判”。实践中,当事人频繁以诉讼标的非同一为由提出管辖权异议,以遗漏必要共同诉讼人为由提起上诉甚至申请再审。民法典的实施未能改变程序导向模式,司法解释和典型案例的实体导向探索反而模糊了必要与普通共同诉讼的界线。在设置模式上,我国较苏联更偏向程序导向,必要共同诉讼的扩大化和恣意化是其固有弊病。实体导向模式存在以德国法为代表的复数诉讼标的形态和以瑞士法为代表的单一诉讼标的形态。单一诉讼标的形态更契合民法典视阈下必要共同诉讼的模式转换需要,即在必要共同诉讼的制度目的上强调实体决定性,在概念内涵上限定为狭义的“诉讼标的共同”,在基本类型上根据我国实体法的自身特色重塑固有/类似必要共同诉讼以及紧密/松散普通共同诉讼,在法律效果上回归民事诉讼法第135条之文义,并协同完善与之配套的程序导向普通共同诉讼制度。

诉权是我国民事诉讼现代化的原点和主线。1982年《民事诉讼法(试行)》建立起扁平化的起诉条件,这不仅动摇了起诉权的权利属性,使民事诉权向私法诉权模式偏移,而且在结果上筑高起诉门槛,引发“起诉难”。2014年《中共中央关于全面推进依法治国若干重大问题的决定》为民事诉权的深刻变革提供了基本思路与科学方法,即将扁平化的起诉条件重塑为阶层化的诉权要件。起诉行为成立要件(第一层)和起诉权构成要件(第二层)实质简化了起诉条件,大幅降低起诉门槛,也为立案登记制改革的再深化提供了理论基础;判决请求权构成要件(第三层)和胜诉权构成要件(第四层)彰显出开庭审理对诉权保障的决定性作用。为有效应对案件数量激增和诉权滥用问题,还应建立健全配套机制,以实现民事诉权的中国式现代化。

Hyperlipidemia is a major risk factor for erectile dysfunction(ED).Oxidative stress and phenotypic modulation of corpus cavernosum smooth muscle cells(CcSMCs)are the key pathological factors of ED.N-acetylcysteine(NAC)can inhibit oxidative stress;however,whether NAc can alleviate pathological variations in the corpus cavernosum and promote erectile function recovery in hyperlipidemic rats remains unclear.A hyperlipidemia model was established using 27 eight-week-old male Sprague-Dawley(SD)rats fed a high-fat and high-cholesterol diet(hyperlipidemic rats,HR).In addition,9 male SD rats were fed a normal diet to serve as controls(NC).HR rats were divided into three groups:HR,HR+normal saline(NS),and HR+NAC(n=9 for each group;NS or NAc intraperitoneal injections were administered daily for 16 weeks).Subsequently,the lipid profiles,erectile function,oxidative stress,phenotypic modulation markers of ccsMCs,and tissue histology were *** experimental results revealed that erectile function was significantly impaired in the HR and HR+NS groups,but enhanced in the HR+NAC *** lipid levels,over-activated oxidative stress,and multi-organ lesions observed in the HR and HR+NS groups were improved in the HR+NAC ***,the HR group showed significant phenotypic modulation of CCSMCs,which was also inhibited by NAC *** report focuses on the therapeutic effect of NAc in restoring erectile function using a hyperlipidemic rat model by preventing CcSMC phenotypic modulationand attenuating oxidativestress.

使用2018年的中国家庭追踪调查数据(CFPS),选取大五人格量表测量非认知能力,综合利用普通最小二乘法、条件分位数回归、无条件分位数回归以及工具变量法,实证检验了非认知能力对城乡户籍人口收入的异质性影响,研究发现:城乡户籍人口非认知能力的收入回报率存在明显差异,相较于城市户籍人口,非认知能力对农村户籍人口收入的影响更大,另外,非认知能力对农村户籍低收入者的影响大于农村户籍高收入者。因此,应当充分发挥教育在解决相对贫困、阻断贫困代际传递中的关键作用,充分发挥财政补偿职能,强化乡村教育中非认知能力的培养。具体来说,应重视农村户籍低收入者非认知能力的培养与提升;将农村学生非认知能力培养贯穿于整个乡村教育过程中;在家庭教育中加强非认知能力培养。
