糖尿病心率变异性分析与微量白蛋白尿的关系

目的 探讨糖尿病患者微白蛋白尿与心脏自主神经病变之间的关系。方法 应用２４小时动态心率变异性（ＨＲＶ）频率分析技术，对４６例糖尿病患者及３１例正常对照者测定了ＨＲＶ，并与尿白蛋白排泄率作相关分析。结果 糖尿病患者在不同尿白蛋白排泄（ＵＡＥ）阶段，心率变异性时域分析各项指标参数均为降低，其中伴微白蛋白尿组（ＤＭＢ）较正常蛋白尿组（ＤＭＡ）ＨＲＶ各项参数降低更明显，有极显著性差异（Ｐ〈０．０１）。糖尿     

Calculation of strong and weak interactions in TDA1 and RangDP52 by the kernel energy method

Using the Kernel Energy Method we apply ab initio quantum mechanics to study the relative importance of weak and strong interactions (including hydrogen bonds) in the crystal structures of the title compounds TDA1 and RangDP52. Perhaps contrary to widespread belief, in these compounds the weak interaction energies, because of their large number and cooperativity, can be significant to the binding energetics of the crystal, and thus also to its other properties.     

眼型Graves病(30例临床分析)

30 cages of Graves were treated Jn our hospital from 1983 to 1999 and analyzed in clinical symptoms,imnune functicns X- ray and CT scan. Graves disease was believed as an autointnune disease due to high lgA and IgM. Its morbidity was 40 - 75% with increasing orbital fat and hypertrophy of extraocular muscles. Tire specific change was high density of orbital apex in CT scan.The diagnosis could be obtained by its symptoms,T3 inhibiting test and CT.The min treatment in early stage was medication such as horamone, immune inhibitor and dialysis. But surgical treatment should by necessary.     

护理人员抽血对检验结果的影响因素探讨

检验结果的准确性与可靠性除了靠检验科室的保证外，同时需要护理人员的配合。作者分析了护理人员抽取检验标本易出现的几个问题，说明护理人员对检验标本的抽取方式、方法也是检验分析质量保证的一个重要方面。建议在护理人员中加强宣传教育，提高对标本抽取中影响因素的认识，与实验室人员一起共同减少因非疾病因素而造成的检验结果异常。     

11种中成药治疗小儿厌食症的网状Meta分析

[目的] 系统评价11种中成药治疗小儿厌食症的相对临床疗效。[方法] 计算机检索中国知网、万方数据知识服务平台、维普数据库、中国生物医学文献数据库、PubMed、Web of Science、the Cochrane Library数据库中有关中成药治疗小儿厌食症的随机对照试验，检索时限为数据库建库至2022年5月5日。使用RevMan 5.3、GeMTC 0.14.3、Stata 14.0软件进行结果呈现和数据分析。[结果] 研究共纳入48项随机对照试验，共计7 113名受试者，涉及11种中成药。网状Meta分析结果显示，不同干预措施的临床总有效率排序结果为：肠胃康颗粒>山麦健脾口服液>芪斛楂颗粒>小儿脾胃乐颗粒>儿康宁>沙棘干乳剂>醒脾养儿颗粒>健身消导颗粒>小儿健脾丸>健胃消食口服液>健胃消食片>常规西药。[结论] 中成药治疗小儿厌食症的疗效较为确切，值得临床推广，且肠胃康颗粒、山麦健脾口服液和芪斛楂颗粒概率排序较为靠前，为最佳干预措施的可能性最大，临床上可结合该研究结果及临床实际情况谨慎选择对患者最优的干预措施进行治疗。

Pathogenic gene screening in 91 Chinese patients with short stature of unknown etiology with a targeted next-generation sequencing panel

Background

Dwarfism is a common severe growth disorder, but the etiology is unclear in the majority of cases. Recombinant human growth hormone may be a treatment option, but it has limited efficacy. The currently known laboratory assays do not meet the precision requirements for clinical diagnosis. Here, we have constructed a targeted next-generation sequencing (NGS) panel of selected genes that are suspected to be associated with dwarfism for genetic screening.

Methods

Genetic screening of 91 children with short stature of unknown etiology was performed with the help of the NGS panel. All the coding regions and exon-intron boundaries of 166 genes were included in the panel. To clarify the pathogenicity of these mutations, their clinical data were reviewed and analyzed.

Results

The assay identified p.A72G, p.I282V, and p.P491S variants of the PTPN11 gene and a p.I437T variant of the SOS1 gene in 4 cases with Noonan syndrome. A frameshift mutation (p.D2407fs) of the ACAN gene was identified in a case of idiopathic short stature with moderately advanced bone age. A p.R904C variant of the COL2A1 gene was found in a patient, who was accordingly diagnosed with Stickler syndrome. Severe short stature without limb deformity was associated with a p.G11A variant of HOXD13. In addition, we evaluated evidence that a p.D401N variant of the COMP gene may cause multiple epiphyseal dysplasia.

Conclusions

Our findings suggest that syndromes, particularly Noonan syndrome, may be overlooked due to atypical clinical features. This gene panel has been verified to be effective for the rapid screening of genetic etiologies associated with short stature and for guiding precision medicine-based clinical management.
