Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance. Methods A total of 3 756 participants were enrolled. Each participant underwent an oral glucose tolerance test and completed a questionnaire. Anthropometric indices were recorded and serum samples were collected for measurement. Results Liver enzymes concentrations were independently associated with i-IGT, iFG＋IGT, and diabetes. With the increase of ALT and GGT concentrations, ORs for i-IGT, IFG＋tGT, and diabetes increased gradually. By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile （Q1）, ORs for iqGT, IFG＋IGT, or diabetes was significant after adjustment. Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR （95% Cl）： 2.56 （1.51-4.34） P=0.00; GGT OR （95% CI）： 2.66 （1.53-4.65） P=0.00]. Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.

教育社会学对教育不平等的研究忽视了对学校教育过程的挖掘。实际上,学校在教育的社会阶层再生产中扮演着重要的角色。学校不断地在学生中间制造等级分层,并且通过一系列策略强化学生对学校内部不平等的认受;来自不同家庭背景的学生对学校的等级策略有着不同的适应性;学校通过公开的分类,以隐蔽的手段将学生的家庭资本与学业前途对应了起来。通过对学校教育过程的深入分析,有助于我们发现教育过程阶层再生产的隐秘。

橄榄型社会阶层结构是中国式现代化的内在要求。当前中国社会结构正处于向橄榄型过渡状态,以统一的分层标准来看,中国社会结构形态是城市为类橄榄型、农村为金字塔型,两者有重叠的菱形三角型结构。但是特殊国情使得城乡之间存在两类不同的分层体系,呈现出有重叠部分的双菱型结构,这种矛盾的社会结构形态既为社会稳定提供了基础,又对橄榄型社会结构的形成提出了挑战。改革开放以来,不断增长且以上升流动为主导的社会流动为社会形成橄榄型结构提供了动力,自致性因素主导的社会流动机制保证了社会流动的公平性,但是社会分层与流动存在的城乡、区域、体制等分割限制了社会结构的进一步优化,这就需要以共享发展理念为指引,推进资源、权利、机会等在各阶层的合理分配,构筑公正合理、开放畅通的社会流动通道。

当前我国社会职业阶层结构的开放对于男性和女性有着不同的意义,代际和代内社会职业阶层流动表明,女性的总流动率和上升流动率均低于男性,女性更多地受到父代尤其是母亲职业地位的影响,而男性则更容易通过自身努力从较低的社会职业阶层跻身到职业地位的上层。由此我们可以理解尽管社会流动率在增加,但是女性与男性的社会地位仍存在着较大的差距。
