This paper proposes a comprehensive investigation on lateral stiffness of corner-supported steel modular frame using splice connection. A full-scale modular frame with two stacked steel modules under lateral load is tested. Ductile pattern in the transfer of lateral load is found in the final failure mode. Two types of lateral stiffness, including tangent stiffness and secant stiffness, are defined from the load-displacement due to the observed nonlinearity. The difference between these two types of stiffness is found around 20%. The comparisons between the experimental lateral stiffness and the predictions of classical methods are also conducted. The D-value method using hypothesis of independent case is a conservative option for predicting lateral stiffness, which is more recommended than method of contraflexural bending moment. Analyses on two classical shortrod models, including fix-rod model and pin-rod model, are further conducted. Results indicate that fix-rod model is more recommended than pin-rod model to simplify splice connection for simulation on lateral stiffness of modular frame in elastic design stage.

Along with China's in-depth development of reform, it has become difficult to effectively deal with the increasingly austere social risks in the countryside and meet the aged residents’pressing demands of a pension guarantee. This article seeks to shed light on the development of the Chinese rural pension policy from a growing body of literature. This article argues that the rise of the new rural pension scheme is directly related to the emerging ideas of “social security for all”, which abandons the previous policy idea that farmers could still rely on their land and family supplemented by private commercial insurance. However, even though the state has become more involved with this issue, the old-age security of farmers in rural China is still standing on very thin ice and the prospect for further more active state involvement in long run remains ambiguous due to many restrictive conditions. There should be more attention to crucial groups including those households that practice family planning by having only one child or two girls, the elderly, and households with no children, and concentrate on some policy instruments like old-age allowances, micro-insurance and tax-free saving plans for the aged. All in all, the target is to make the rural social old-age security system match with the traditional family protection, collective mutual aid organizations so as to construct Chinese characteristics of multi-level old-age security system between rural and urban areas.

China`s Land System Reform: Balancing Redistribution and Market Mechanism

( Yang Yi-fan ),( Kim Pan Suk ) 한국외국어대학교 중국연구소 2016 中國硏究 Vol.68 No.-

Whether China`s land system should be significantly changed is a hot but controversial topic in both theory and practice. A study of the Chongqing-Chengdu experimental area in Sichuan province has shown that both market and redistribution mechanisms are involved in reform. Previously, however, people have commented that there is not enough reliance on the market mechanism. This article argues that China`s current land system arrangement has an advantage in that the government can more easily mobilize resources and land revenue to balance development between rural and urban areas. However, its efficiency still needs to be improved by introducing a pricing mechanism. The article provides much valuable evidence for the improvement of relevant land reform policies, which will be conducive to other developing countries wishing to learn from China`s experience.

Internationally, how to achieve sustainable cities development is the focus of the UN’s 2030 Agenda for Sustainable Development (SDGs 2030). On the agenda, Sustainable Development Goal 11 (SDG 11) is to “Make cities and human settlements inclusive, safe, resilient and sustainable”. This agenda not only requires member states to formulate development strategies at the national level, but also demands local government to make reform and innovation in governance. Nowadays, the ageing of Chinese society is deepening. In the public space, conflicts between the younger generation and the older generation are frequent, which poses huge challenges to public governance: How to create a safe, resilient and sustainable public space? How to enhance societal resilience in various communities? Through in-depth study of specific cases, practical investigation, policy analysis and literature analysis, we realized that behind the competition of square dance space, there are actually hidden role differences and inter-generational conflicts between the two generations. This paper will start from the case introduction and analysis to explore how to deal with space competition of square dance and alleviate inter-generational conflict. At the same time, from the perspective of public governance, this paper puts forward the idea of creating resilient communities with the resilience capacity framework theory to enhance societal resilience and sustainable development of communities.

Precirrhotic Primary Biliary Cholangitis with Portal Hypertension: Bile Duct Injury Correlate

Hu Yi-Fan,Li Shun-Xin,Liu Hong-Li,Du Zhi-Xiang,Wang Shuang-Shuang,Chen Miao-Yang,Wang Li,Xiong Qing-Fang,Zhong Yan-Dan,Liu Du-Xian,Yang Yong-Feng 거트앤리버 소화기연관학회협의회 2024 Gut and Liver Vol.18 No.5

Background/Aims: The histological characteristics and natural history of precirrhotic primary biliary cholangitis (PBC) with portal hypertension (PH) are unclear. Our aim was to clarify the prevalence, risk factors, and histological characteristics of precirrhotic PBC patients with PH. Methods: This retrospective study compared the clinical features, histological characteristics, and response to ursodeoxycholic acid (UDCA) between the PH and non-PH groups of precirrhotic PBC patients. Results: Out of 165 precirrhotic PBC patients, 40 (24.2%) also had PH. According to histological stage 1, 2 and 3 disease, 5.3% (1/19), 17.3% (17/98), and 45.8% (22/48) of patients also had PH, respectively. Precirrhotic PBC with PH was significantly positively correlated with bile duct loss, degree of cytokeratin 7 positivity, and degree of fibrosis in the portal area, but significantly negatively correlated with lymphoid follicular aggregation. Compared to the non-PH group, patients in the PH group showed a higher prevalence of obliterative portal venopathy, incomplete septal fibrosis, portal tract abnormalities and non-zonal sinusoidal dilatation (p<0.05). In addition, patients with PH were more likely to present with symptoms of jaundice, ascites, epigastric discomfort, a poorer response to UDCA, and more decompensation events (p<0.05). High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values were risk factors for precirrhotic PBC with PH. Conclusions: Approximately 24.2% of precirrhotic PBC patients have PH, which is histologically related to the injury of bile ducts. High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values are associated with increased risk of precirrhotic PBC with PH.

Aims: Genome-wide association studies (GWAS) have identified several risk variants for prostate cancer (pCa) mainly in Europeans, which need to be further verified in other racial groups. We selected six previously identified variants as candidates and to define the association with PCa in Northern Han Chinese. Methods: 749 subjects from Beijing and Tianjin in Northern China were included. Six variants (rs10505474, rs7837328, rs4242384, rs7813, rs486907 and rs1058205) were genotyped by high resolution melting (HRM) assays. The individual and cumulative contribution for of the risk of PCa and clinical covariates were analyzed. Results: Among the six candidate variants, onlyrs10505474, and rs7837328, both locating at 8q24 region, were associated with PCa in our population.rs10505474 (A) was associated with PCa ($OR_{recessive}=1.56$, p=0.006); and rs7837328 (A) was associated with PCa ($OR_{dominant}=1.38$, p=0.042/$OR_{recessive}=1.99$, p=0.003). Moreover, we observed a cumulative effects between them ($p_{trend}=2.58{\times}10^{-5}$). The joint population attributable risk showed the two variants might account for 71.85% of PCa risk. In addition, we found the homozygotes of rs10505474 (A) and rs7837328 (A) were associated with PCa clinical covariants (age at onset, tumor stage, respectively) ($p_{age}=0.046$, $P_{tumorstage}=0.048$). Conclusion: rs10505474 (A) and rs7387328 (A) at 8q24 are associated with PCa and cumulatively confer risk, suggesting the two variations could determine susceptibility to PCa in the Northern Chinese Han population.

Purpose Gastric cancer (GC) has high morbidity and mortality, the cure rate of surgical treatment and drug chemotherapy is not ideal. Therefore, development of new treatment strategies is necessary. We aimed to identify the mechanism underlying Sp1 regulation of GC progression. Methods and Methods The levels of Sp1, β-catenin, SET domain bifurcated 1 (SETDB1), and 15-hydroxyprostaglandin dehydrogenase (HPGD) were detected by quantitative reverse transcription polymerase chain reaction and western blot analysis. The targets of SETDB1 were predicted by AnimalTFDB, and dual-luciferase reporter assay was used for confirming the combination of Sp1, β-catenin, and SETDB1. HGC27 or AGS cells (1×106 cells/mouse) were injected into mice via the caudal vein for GC model establishment. The level of Ki67 was detected using immunohistochemistry, and hematoxylin and eosin staining was performed for evaluating tumor metastasis in mice with GC. Results HPGD was inhibited, while the protein levels of Sp1, β-catenin, and SETDB1 were up-regulated in GC tissues and cell lines. HPGD overexpression or SETDB1 silencing inhibited the proliferation, invasion, and migration of GC cells, and Sp1 regulated the proliferation, invasion, and migration of GC cells in a β-catenin-dependent manner. Furthermore, HPGD served as a target of SETDB1, and it was negatively regulated by SETDB1; additionally, Sp1 and β-catenin bound to the SETDB1 promoter and negatively regulated HPGD expression. We proved that Sp1 regulated GC progression via the SETDB1/HPGD axis. Conclusions Our findings revealed that Sp1 transcriptionally inhibited HPGD via SETDB1 in a β-catenin-dependent manner and promoted the proliferation and metastasis of GC cells.
