ABSTRACT
ObjectiveTo analyze the application of International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) in China. MethodsResearches using ISNCSCI in the spinal cord injury were retrieved from CNKI, from January 1st, 2020 to December 31st, 2022. The authors and the keywords of the included literatures were analyzed using VOSviewer and CiteSpace to generate a collaboration network graph of authors and a theme distribution map of keywords. The objects, purposes, causes of spinal cord injury, distribution of researchers' departments, ISNCSCI version used, corresponding publication time and other information of the included studies were manual searched and analyzed. ResultsA total of 285 literatures were finally included, involving 1 279 authors, out of whom 111 published 97.19% of the total number of articles. The main keywords included spinal cord injury, spinal fractures, neurological function, thoracolumbar fractures and spinal tuberculosis, which classified in seven clusters, and the topics of spinal cord injury, efficacy, spinal fractures, quality of life and prognosis were the hotspots in the field. With manual searching, the main topic was spinal cord injury; the main object was traumatic spinal cord injury; the main purpose was to evaluate the surgical efficacy; the research institutions were mostly the comprehensive hospitals or specialized hospitals focusing on orthopedics (spinal surgery); the clinical departments that used ISNCSCI the most were orthopedics (including spinal surgery) and rehabilitation medicine, and nursing teams were paying more attention to ISNCSCI; the most commonly used versions of ISNCSCI were 2011 (7th edition) and 2000 (6th edition), however, for a large number of articles, the versions were not clear or earlier than 2000. ConclusionThe application of ISNCSCI in China should be improved in the standardization.
ABSTRACT
Objective To estabolish the ALDH2 Glu504Lys genotyping technique for oral swab sample type based on PCR-gold magnetic nanoparticle chromatographyl.Methods According to the ALDH2 Glu504Lys gene the specific primers were designed by ARMS-PCR technique.Optimized the optimal ALDH2 Glu504Lys oral swab reaction system and PCR reaction procedures based on the routine reaction conditions and reaction procedure of laboratory PCR.60 samples of oral swabs were collected and tested by gold magnetic nano-chromatography.The results were verified by sequencing.Results The detected 60 cases of oral swab samples contain 16 cases heterozygous mutation,wild type 42 cases,homozygous mutation 2 cases and then the results by Goldmag nanoparticle detection was perfectly matched with sequencing results.Conclusion The Goldmag nanoparticles chromatographic detection technique of ALDH2 Glu504Lys buccal swabs system was established.With accuracy,fastness,reliability,it is worthy of clinical promotion.
ABSTRACT
<p><b>OBJECTIVE</b>To detect JAK2 V617F mutation burden and its clinical implications in patients with myeloproliferative neoplasm (MPN).</p><p><b>METHODS</b>JAK2 V617F mutation burden were detected by using MGB Taqman probes and its clinical significance were retrospectively studied in 415 MPN patients.</p><p><b>RESULTS</b>JAK2 V617F was found in 56.9% of all patients [83.5% in polycythemia vera (PV), 55.9% in essential thrombocythemia (ET), 41.9% in primary myelofibrosis (PMF) and 64.7% in MPN-unclassifiable)]. The majority of patients carried heterozygous JAK2 V617F mutation and homozygote was found only in 12 cases (4 in PV, 4 in MPN-U, 2 in PMF, 1 in ET, and 1 in chronic neutrophilic leukemia). Most patients (68.8%) were lower mutation burden (mutation burden<50%), but PV had the highest burden, the moderate burden in PMF and the least in ET. The patient's age and WBC count were significantly correlated with higher mutation burden in PV. WBC count was significantly related to higher mutation burden in ET. WBC count, Hb level and the platelet count were significantly related to higher mutation burden in PMF.</p><p><b>CONCLUSION</b>The mutation burden of JAK2 V617F from high to low was PV, ET and PMF. The majority of JAK2 V617F mutation was heterozygous. JAK2 V617F mutation burden was positively correlated with age, WBC, Hb and platelet counts.</p>

Ninety-two cases of enuresis were treated with auricular point pressure onthe kidney (MA-SC), bladder (MA-SC 8), lung (MA-IC 1), heart (MA-IC), liver (MA-SC 5), Er Shenmen(MA-TF 1),Zhen (MA-AT) and Subcortex (MA-AT 1) plus tuina. After treatment, 61 cases were cured, 28 cases were effective and 3 cases were ineffective, with an effective rate of 96.7%.
