The non-parametric rank sum test was used to compare the liver function indexes and immunoglobulins in different intensity groups of anti-SLA. P<0.05 was considered statistically significant. Further comparisons were made between the two groups, the correction level α′=0.008 3, P<0.008 3 was considered statistically significant. \u0000 \u0000 \u0000Results \u0000The average age of 77 anti-SLA positive patients was (52.50±1.25) years old, 70 females (90.9%) and 7 males (9.1%). 80.5% of anti-SLA-positive patients (62/77 cases) were strongly positive at the time of initial diagnosis (+++ to ++++).The Alanine aminotransferase (ALT) level in the SLA++ group was higher than that in the SLA++++ group (232.7 U/L vs 65.6 U/L,χ2=7.751,P=0.005) and the immunoglobulin M(IgM) level in the SLA+++ group was lower than that in the SLA++++ group (1 270 mg/L vs 2 270 mg/L,χ2=8.337,P=0.004).There was no significant difference in age, other liver function and immunological indicators among the different groups.Seventy cases (90.9%) were both anti-SLA and ANA positive, 13 cases (16.9%) were positive with SMA, and none positive with anti-LKM and anti-LC1. Among anti-SLA positive patients, 58 cases were diagnosed with autoimmune hepatitis (AIH), 12 were AIH/primary biliary cholangitis (PBC) overlap syndrome (OS), 2 were drug-induced liver injury, 2 were chronic hepatitis B, and 3 were hepatitis A, hepatitis E and acquired immune deficiency syndrome (AIDS) with liver injury, respectively.Cases of AIH and AIH/PBC OS accounted for 90.9% (70/77 cases) of anti-SLA-positive patients, and 5 of 7 patients diagnosed with non-AIH (and OS) had elevated IgG, showing AIH feature.92.3% (12/13 cases) of anti-SLA with high titers of AMA were diagnosed as AIH/PBC overlap syndrome. Of the 77 anti-SLA-positive patients, 28 (36.4%) had advanced or end-stage liver disease, including decompensated cirrhosis (22 cases), chronic acute liver failure (4 cases), and liver transplantation (1 case) and death from liver failure (1 case). \u0000 \u0000 \u0000Conclusions \u0000Anti-SLA has high diagnostic specificity for AIH;anti-SLA positive in patients with PBC should be an important biomarker for the diagnosis of AIH/PBC overlap syndrome. \u0000 \u0000 ","PeriodicalId":10096,"journal":{"name":"中华检验医学杂志","volume":"23 1","pages":"927-932"},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75084880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a high correlation between glucose concentration in interstitial fluid and glucose concentration in blood. Real-time monitoring of glucose concentration in interstitial fluid has important clinical significance. Continuous glucose monitoring (CGM) is an emerging glucose monitoring technology, which indirectly reflects the blood glucose level of the body through the glucose level in the interstitial fluid, providing continuous and comprehensive information and rules of blood glucose variation over a period of time. There are three main categories of CGM: minimally invasive implantation, non-invasive microtransparency and non-invasive technology. Noninvasive blood glucose monitoring technology is the future development direction, but accuracy and delay of blood glucose will be the biggest challenge to be overcome in clinical application. \u0000 \u0000 \u0000Key words: \u0000Blood glucose monitoring; Continuous glucose monitoring; Noninvasive glucose monitoring","PeriodicalId":10096,"journal":{"name":"中华检验医学杂志","volume":"29 1","pages":"914-918"},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81487957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
