目的探讨磁共振成像(MRI)在踝关节骨折伴发韧带损伤诊断中的应用价值。方法收集南昌大学第三附属医院2015年1月至2018年1月收治的踝关节骨折患者138例,按Ashurst和Bromer分型分为内收型32例、外展型47例、外旋型33例和垂直型26例。所有病例均行MRI检查,分析踝关节韧带、关节软骨损伤情况及关节腔积液积血发生情况,并与术中或关节镜下探查结果进行比较。结果138例踝关节骨折患者,MRI诊断韧带损伤83例,术中或关节镜下探查韧带损伤69例,MRI诊断准确率为83.13%(69/83),其中内收型、外展型、外旋型、垂直型韧带损伤MRI诊断准确率分别为83.33%(15/18)、83.33%(20/24)、85.71%(18/21)、80.00%(16/20);韧带损伤部位MRI诊断准确率为74.95%(74/99),其中内侧三角韧带损伤、外侧副韧带损伤、下胫腓联合韧带损伤准确率分别为71.88%(23/32)、85.37%(35/41)、61.54%(16/26)。83例手术患者,MRI预测术后创伤性关节炎发生率为10.84%(9/83),与随访12个月后的实际发生率13.25%(11/83)相比,差异无统计学意义(χ^2=0.802,P=0.350)。结论MRI能明确显示踝关节骨折韧带、关节软骨受损情况,指导临床制定完善的治疗计划,对术后关节修复的评估及预测严重并发症的发生有重要价值。

Iron is a crucial micronutrient, and its deficiency can have detrimental effects on the health of infants. Dietary polysaccharide-iron(Ⅲ) complexes(PICs) are promising for addressing iron deficiency due to their minimal adverse reactions and high iron absorption rate. This study aimed to investigate the effects of dietary Enteromorpha prolifera polysaccharide-Fe(Ⅲ) complex(EP-Fe) on newborns, using 3-day weaned piglets as the iron-deficiency model. Results showed that EP-Fe improved iron levels and promoted intestinal development in piglets. Transcriptome sequencing revealed that EP-Fe increased the survival of intestinal epithelial cells under hypoxia by upregulating the expression of genes that promote the development of the vascular system. Additionally, EP-Fe enhanced the mucosal barrier functions by inhibiting myosin light chain kinase(MLCK)/phosphorylated myosin light chain(p-MLC) signaling pathway to increase the expression of intestinal tight junction proteins. Furthermore, the 16S r RNA gene sequencing of gut microbiota showed that EP-Fe promoted the enrichment of Bacteroides＿fragilis and other gut microbes that can metabolize carbohydrates. In conclusion, EP-Fe is an effective iron supplement for newborns, and it can be developed as a comprehensive nutritional supplement.

Dinuclear metal synergistic catalysis （DMSC） has been proved powerful in boosting CO2reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework （MOF）,obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center （M-In）,three MOFs with dinuclear homometallic catalytic centers （MM-In）,and three MOFs with dinuclear heterometallic catalytic centers (MM’-In,M/M’=Co（II）,Ni（II）,Zn（II）).It was found that all these MOFs can serve as catalysts for photochemical CO2reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g-1h-1,which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO2reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO2reduction.

作者：宋殊琪王磊峰董玉萍姚毅武警北京总队第二医院眼科中国北京市100037 解放军总医院眼科中国北京市100853

目的:对比分析玻璃体黄斑牵引综合征(vitreomacular traction syndrome,VTS)手术前后光学相干断层扫描(optical coherence tomography,OCT)的差异。方法:回顾性分析2013-01/2014-01经OCT检查确诊并接受25G玻璃体切除手术治疗的玻璃体黄斑牵引综合征患者11例11眼的临床资料。患者术后平均随访6mo,观察患者手术前后的视力及OCT检查情况,比较手术前后黄斑区视网膜厚度和局部形态的变化。结果:单纯玻璃体牵引8眼,术后6眼视力提高,2眼视力不提高;黄斑前膜牵引1眼(术中给予黄斑前膜剥除、视网膜内界膜剥除、曲安奈德玻璃体腔注射)术后视力不提高;玻璃体合并视网膜黄斑前膜牵引2眼(术中给予黄斑前膜剥除)术后视力提高。其中视力达0.1以上者所占比例由术前的46%提高至术后的73%。术前黄斑中心凹视网膜平均厚度为619.27±195.13μm,术后平均厚度为239.12±143.84μm,术后黄斑中心凹视网膜平均厚度较术前明显减少,差异有统计学意义(P<0.05)。结论:玻璃体切除术能有效解除玻璃体对黄斑部的牵引,阻止患者视力进一步下降,减轻黄斑水肿,并提高部分患者视力,OCT对本组病的诊断及预后有重要的指导意义。
