目的了解低血磷性佝偻病(hypophosphatemic rickets,HR)患儿的诊断、治疗及并发症情况,探讨疾病疗效评价指标,了解患儿身高增长规律。方法回顾性分析2008年1月—2022年12月于南京医科大学附属儿童医院诊治的85例HR患儿的首诊临床资料及5年随访资料。结果85例HR患儿中,男性46例(54%),女性39例(46%);首诊年龄范围为6个月至13岁9个月,中位年龄为2.75岁;平均身高标准差数值为-2.0±1.1。首诊时患儿血磷降低,血碱性磷酸酶(alkaline phosphatase,ALP)升高,99%(84/85)患儿存在下肢畸形,PHEX基因突变阳性率为93%(55/59)。患儿治疗1年后ALP水平及双下肢间距较前明显减低(P<0.05)。患儿身高在治疗后第1年增长最快,为8.23 cm/年;存在青春期身高突增峰速度(peak height velocity,PHV)阶段,持续约2年,男性患儿PHV阶段身高共增长9~20 cm,女性患儿PHV阶段身高共增长10~15 cm。患儿主要并发症为肾钙质沉着及甲状旁腺功能亢进。肾钙质沉着治疗后第1年发生率为55%(22/40),其发生率随病程延长而增加(P<0.001);尿磷/尿肌酐比值升高与肾钙质沉着的风险升高呈正性关联(OR=1.740,P<0.001)。甲状旁腺功能亢进治疗后第1年发生率为64%(27/42)。结论对存在下肢畸形、身材矮小、生长缓慢的儿童,及早进行血磷、血钙、ALP检测及下肢影像学检查有助HR的早期诊断,必要时可结合基因检测确诊。ALP结合骨骼畸形改善及身高年增长情况可作为HR治疗疗效的评价指标。患儿青春期PHV阶段身高总增长小于正常儿童,需密切随访,及时调整治疗方案.

Journal of Iron and Steel Research International 2014年第2期21卷 269-274页

作者： ai-hua CHEN Hai-rong GUO hua-long LI Toshihiko EMI Institute of Research of Iron and Steel Shasteel

Microstructure evolution, dynamic recrystallization, high temperature oxidation and hot ductility of 1.4 % Si non-oriented electrical steel sheets were investigated to reduce edge cracking. The causes of cracking were found to be coarse as-cast microstructure, grain boundary oxidation in reheating furnace, lack of dynamic recrystallization during hot rolling and increase of temperature, resulting in reduced hot ductility in strip edge region. Countermeas- ures against the edge crack are proposed accordingly. Lowering reheating temperature and reducing holding time re- duced oxidation and decarburization. Hot charging temperature was increased to decrease reheating temperature. And using an edger can refine microstructure in strip edge region. Finally, edge heater can be added to increase edge re- gion formability by inducing dynamic reerystallization and ductility by increasing temperature.

For the solid-solid transformation from form Ⅱ to form Ⅰ of isotactic polybutene-1(iPB),the temperature dependence of form Ⅰ nucleation and growth was deemed to control the transformation ***,the relationship between formⅠ formation and form Ⅱ disappearance in the transformation process is not *** this work,the spontaneous crystal transformation from form Ⅱ to Ⅰ of iPB with 81 mol%mmmm sequence concentration is studied firstly by tracking the two processes,the decay of form Ⅱ and the yielding of form Ⅰ in a wide range of temperature spanning from 0℃ to 50℃ and in a long transformation time ranging from 5 min to 65 days with in situ FTIR and *** the literature reports,the decay rate of form Ⅱ is firstly found to be lower than the yielding rate of form Ⅰ at all studied temperatures,especially at low transition *** is attributed to the amorphous chains which locate near crystal lamella participating into the nucleation of form Ⅱ.The regular chain folding and growth of i PB form Ⅰ from amorphous chains containing short isotactic sequences also lead to an increase in crystallinity of form Ⅰ compared with that of initial form Ⅱ crystallized at 60℃.An increase in the annealing temperature results in decrease in crystallinity and increase in lamellae thickness of i PB formⅠ.

Epilepsy is a chronic and severe neurological disorder that has negative effects on the autonomous activities of patients. Functionally, Trem2(triggering receptor expressed on myeloid cells-2) is an immunoglobulin receptor that affects neurological and psychiatric genetic diseases. Based on this rationale, we aimed to assess the potential role of Trem2 integration with the PI3 K/Akt pathway in epilepsy. We used microarray-based gene expression profiling to identify epilepsy-related differentially-expressed genes. In a mouse hippocampal neuron model of epilepsy, neurons were treated with lowMg^2+ extracellular fluid, and the protein and mRNA expression of Trem2 were determined. Using a gain-offunction approach with Trem2, neuronal apoptosis and its related factors were assessed by flow cytometry, RT-qPCR,and Western blot analysis. In a pilocarpine-induced epileptic mouse model, the malondialdehyde(MDA) and8-hydroxy-20-deoxyguanosine(8-OHdG) content and superoxide dismutase(SOD) and glutathione-peroxidase(GSH-Px) activity in the hippocampus were determined,and the protein expression of Trem2 was measured. In addition, the regulatory effect of Trem2 on the PI3 K/Akt pathway was analyzed by inhibiting this pathway in both the cell and mouse models of epilepsy. Trem2 was found to occupy a core position and was correlated with ***2 was decreased in the hippocampus of epileptic miceand epileptic hippocampal neurons. Of crucial importance,overexpression of Trem2 activated the PI3 K/Akt pathway to inhibit neuronal apoptosis. Moreover, activation of the PI3 K/Akt pathway through over-expression of Trem2 alleviated oxidative stress, as shown by the increased expression of SOD and GSH-Px and the decreased expression of MDA and 8-OHdG. The current study defines the potential role of Trem2 in inhibiting the development of epilepsy, indicating that Trem2 up-regulation alleviates hippocampal neuronal injury and oxidative stress, and inhibits neuronal apoptosis in epilepsy
