目的探讨血清同型半胱氨酸(Hcy)、低密度脂蛋白胆固醇(LDL-C)及糖化血红蛋白(HbA1c)在2型糖尿病视网膜病变(DR)中的影响。方法回顾性分析2019年4月—2022年6月本院内分泌科住院的2型糖尿病患者有糖尿病视网膜病变组(DR组)患者150例和非糖尿病视网膜病变(NDR组)患者150例的临床资料,包括每位患者的一般资料、生化指标。比较两组间的一般信息;分析DR组与NDR组的影响因素;多元素回归分析DR的危险因素。结果DR及NDR组患者年龄、病程方面差距具有统计学意义(P<0.05)。DR组患者Hcy、FBG、TG、LDL-C、HbA1c水平明显高于NDR组(P<0.05)。Pearson相关系数分析,DR组患者的Hcy与年龄,病程FBG、TG、TC、LDL-c、HbA1c呈正相关关系(P<0.05)。Logistics回归分析结果显示病程、TG、LDL-c、Hcy、HbA1c均是影响2型糖尿病视网膜病变的独立因素(P<0.05)。结论Hcy、LDL-c、HbA1c水平在DR患者中远高于NDR患者,三者与DR发生、发展存在一定联系,临床可根据其表达水平对患者病情变化进行有效评估。

Peperomia pellucida(L.) Kunth is a medicinal plant used to manage inflammatory illnesses such as conjunctivitis, and gastrointestinal and respiratory tract disorders in tropical and subtropical ***, little is known about its pharmacological mechanism of action against eye diseases. This review aims to critically discuss the phytochemistry, pharmacology and toxicology of P. pellucida as well as its roles in the treatment of cataract, glaucoma and diabetic retinopathy. Recent developments in the uses of P. pellucida for healthcare and nutraceutical products by the pharmaceutical industry are also covered in this review. For this review, a literature search was performed with PubMed, ScienceDirect, SciFinder Scholar and Scopus databases, using relevant keywords. Among the various phytochemicals identified from P. pellucida, β-caryophyllene, carotol, dillapiole, ellagic acid, pellucidin A, phytol and vitexin exhibit strong pharmacological activities within the mitogen-activated protein kinase and nuclear factor-κB signalling pathways in inflammatory eye diseases. The antihypertensive, anti-inflammatory, antioxidant,antihyperglycemic and anti-angiogenic activities displayed by P. pellucida extracts in many in vitro,in vivo and clinical studies suggest its potential role in the management of inflammatory eye diseases.P. pellucida extract was non-toxic against normal cell lines but displayed mild toxicity in animal *** growing public interest in P. pellucida has inspired the nutraceutical and pharmaceutical industries to process the plant into health products. Although the potential pharmacological mechanisms against eye diseases have been summarized, further studies of the interactions among constituent phytochemicals from P. pellucida within various signalling pathways shall support the use of the plant as an alternative therapeutic source.

New dibutyltin(IV) complexes of Schiff base derived from 5-chloroindoline-2,3-dione, indoline- 2,3-dione with amino acids (tryptophan, alanine and valine) were synthesized and characterized by elemental analysis, IR, electronic spectra, conductance measurements, and biological activity. The analytical data showed that the Schiff base ligand acts as bidentate towards metal ions via the azomethine nitrogen and carboxylate oxygen by a stoichiometric reaction of M:L (1:2) to form metal complexes. NMR (1H, 13C and 119Sn) spectral data of the ligands and metal complex agree with proposed structures. The conductivity values between 14 - 27 ohm-1cm2mol-1 in DMF imply the presence of non-electrolyte species. 3D molecular modeling and analysis of bond lengths and bond angles have also been conducted for a representative compound, [Bu2Sn(L2)2], to substantiate the proposed structures. Antibacterial results indicate that the metal complexes are more active than the free ligands.

China City Planning Review 2012年第1期21卷 14-19页

作者： Peter G. Rowe har Ye Kan Architecture and Urban Design and University Harvard University Graduate School of Design Harvard University

In recent years, the conservation of industrial heritage in China has gained increasing attention within the broader context of urban conservation practices. For both policy-makers and scholars, accommodating this industrial heritage will emerge as a pertinent issue for consideration as a growing number of industrial architectural legacies dating from the Republican and Maoist eras come under (re)development pressures. This paper thus traces the development of industrial heritage conservation practices in China and discusses several dilemmas intrinsic to this type of conservation, including issues of authenticity, representativeness, and distinction. Based on comparative case studies from China and other international precedents, this paper also seeks to illustrate the different approaches that could be pursued while still attaining a balance between competing interests and claims.

目的结肠炎是先天性巨结肠患儿常见的并发症,组织学研究表明巨结肠性肠炎患儿肠粘膜内的内分泌细胞减少和粘膜内分泌型 IgA不足。而Cdx1和Cdx2基因调控结肠粘膜上皮细胞的分化和增殖,本研究的目的是明确Cdx1和Cdx2基因表达与先天性巨结肠性肠炎之间的关系。方法采用半定量RT-PCR反应和原位杂交方法,11例先天性巨结肠患儿(年龄1～30个月,4例合并结肠炎)的无神经节细胞段、移行段和扩张段的手术切除标本为病例组,12例年龄相符(1～30个月)的非巨结肠患儿的远端结肠标本为对照组,观察Cdx1和Cdx2基因在其中的表达情况。结果Cdx1和Cdx2基因在对比组和先天性巨结肠的结肠粘膜上皮细胞均有表达,但是此二基因在先天性巨结肠性肠炎患儿的标本中表达明显减弱。结论本研究结果表明Cdx1和Cdx2基因表达减弱与先天性巨结肠性肠炎的病因密切相关。

本试验采用25个新的大豆品系为材料,用Robinson等的公式计算了选择指数的遗传进展;用Johnson等的公式计算了直接选择产量的遗传进展;用选择指数的遗传进展占直接选择产量的遗传进展的百分率表示选择指数的相对选择效率;用判别函数求得选择指数的公式。试验结果表明:除了单因子指数选择的效率低于直接选择产量的效率外,所有的指数选择效率都高于直接选择产量。包括所有10个性状的指数选择效的相对效率最高(115.25％)。从经济和简便的角度出发,我们认为包括5个性状(小区产量,熟期,株高,每株荚数,百粒重)的指数选择是可行的。它的相对选择效率是114.07％。
