Since 1992, China has promoted hepatitis B vaccination. Concurrently, during this period, increasing use of immunoglobulins and nucleoside analogues might have exerted selective pressure on the hepatitis B virus (HBV) S gene, driving mutations in the HBsAg and changed the subtype. Using the National Center for Biotechnology Information database, we obtained gene sequence information for HBV strains from China and analysed changes in HBsAg subtypes and substitution mutations in HBsAg in 5-year intervals over 25 years to identify potential challenges to the prevention and treatment of hepatitis B. Most HBV sequences from China were genotype C (1996/2833, 70.46%) or B (706/2833, 24.92%). During the implementation of hepatitis B vaccination (recombinant hepatitis B vaccine was subgenotype A2 and HBsAg subtype adw2), the proportion of subtypes ayw1 and adw3 in genotype B and ayw2 in genotype C increased over the programme period. The overall mutation rate in HBsAg tended to decrease for genotype B, whereas, for genotype C, the rate increased gradually and then decreased slightly. Moreover, the mutation rate at some HBsAg amino acid sites (such as sG145 of genotype B and sG130 and sK141 of genotype C) is gradually increasing. HBV strains with internal stop codons of HBsAg (e.g., sC69*) and additional N-glycosylation (e.g., sG130N) mutations should be studied extensively to prevent them from becoming dominant circulating strains. The development of HBV vaccines and antiviral immunoglobulins and use of antiviral drugs may require making corresponding changes.

OBJECTIVE To quantitatively analyze the association between cholesterol efflux capacity (CEC) and the risk and prognosis of coronary artery disease (CAD). METHODS A systematic search of electronic databases for studies published until September 2019 was performed. Cohorts, case-control studies, and randomized controlled trials that examined the effect of CEC on the risk and prognosis of CAD were included. RESULTS Eighteen studies with 12 685 subjects met our inclusion criteria. Among them, 14 studies reported the CEC in non-CAD and CAD groups, and eight studies reported the association between CEC and risk of CAD. Four studies reported the prognosis of stable CAD or acute coronary syndrome (ACS). In the pooled analyses, significantly decreased CEC was found in patients with stable CAD as compared with those without CAD. Decreased CEC was also present in subgroup in patients with ACS. High CEC was significantly associated with decreased risk of CAD [odds ratio (OR) = 0.65, 95% confidence interval (CI): 0.55-0.75, P

We analyzed the differences in serum homocysteine levels between patients with a history of recurrent spontaneous abortion (RSA) and those who had not experienced pregnancy-related complications. To this end, we retrieved literature and data on the association of RSA and serum homocysteine levels published before September 1st 2019 from the PubMed, EMBASE, China National Knowledge Infrastructure, and Wanfang databases. We further narrowed our literature review by focusing on peer-reviewed and full-text literature reporting on studies that used similar research methods and provided raw data or means and standard deviations while reporting results. Utilizing Stata 12.0 for a combined statistical analysis of the data, we assessed the quality of the included literature using the Newcastle Ottawa Scale. Patients who experienced RSA had higher serum homocysteine levels than the controls, with the difference being statistically significant (

Background YKL-40, a chitinase-like glycoprotein has been identified as a candidate tumor marker. The current study evaluated the clinical significance of plasma YKL-40 in esophageal cancer patients. Methods We enrolled 127 esophageal cancer patients, 29 healthy controls. Plasma YKL-40 levels were measured through enzyme linked immunosorbent assay. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic efficiency of plasma YKL-40 in esophageal cancer patients. The correlations between plasma YKL-40 and clinicopathological characteristics of esophageal were analyzed. Results Plasma YKL-40 levels were significantly higher in patients with lymph node metastasis than those that were non-metastatic (p = 0.005). Patients with tumor thrombus formation presented with significantly higher YKL-40 levels than those without thrombus formation (160.3 vs. 74.7 ng/mL, p = 0.012). YKL-40 levels in patients with advanced stage (III and IV) were significantly higher than those in the early stages (I and II, p = 0.016). ROC curve analysis showed that the area under curve was 0.909, and the best diagnostic threshold of YKL-40 for esophageal cancer was 80.6 ng/mL with 68.9% sensitivity and 96.6% specificity. Conclusions This study indicated that YKL-40 may be a biomarker for esophageal cancer and potential biomarker for identification of invasive esophageal cancer.

IntroductionPregnancy in patients with mechanical heart valves (MHVs) is associated with high maternal complications and fetal complications.Anticoagulation treatments serve to decrease their venous clotting risk. Although some anticoagulation regimens have been used for patients during pregnancy with MHVs, no one is definitively superior among different regimens in recent studies. For a better understanding of the clinical treatment which anticoagulation regimen is more effective and safer during the pregnancy in patients with MHVs, a Bayesian network meta-analysis is necessary.Methods and analysisThis protocol has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Related studies until April 2019 will be searched in the following databases: PubMed, Embase,SinoMed and the using the OVID interface to search for evidence-based medicine reviews. A clinical trial registry (www.ClinicalTrials.gov) was also searched for unpublished trials. Both experimental studies (randomised clinical trials) and observational studies (cohort studies, case–control studies and case series studies) will be included in this study. Quality assessment will be conducted using Cochrane Collaboration’s tool or Newcastle-Ottawa Scale based on their study designs. The primary outcomes of interest will be the frequencies of serious maternal and fetal events. The additional outcomes of interest will be adverse maternal events, mode of delivery and adverse fetal events. Pairwise and network meta-analysis will be conducted using R (V.3.4.4, R Foundation for Statistical Computing, Vienna, Austria) and Stata (V.14, StataCorp). The ranking probabilities will be estimated at each possible rank for each anticoagulation regimen using the surface under the cumulative ranking curve. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed.Ethics and disseminationEither ethics approval or patient consent is not necessary, because this study will be based on literature. The results of this study will be published in a peer-reviewed journal.PROSPERO registration numberCRD42019130659

Background This 4-year retrospective cohort study aimed to establish reference intervals for free triiodothyronine (FT3), free thyroxine (FT4), and thyrotropin (TSH) in premature infants using the Beckman Coulter Unicel DxI 800 automated immunoassay system. Methods Study subjects included 605 preterm infants with a gestational age of 26–36 weeks (corrected: 29–38 weeks). Pearson correlation was used to evaluate the association between hormone levels and gestational and corrected gestational ages. A nonparametric method was used to establish reference intervals based on corrected gestational age. Results FT3 and FT4 levels were positively correlated with gestational and corrected gestational ages, respectively. TSH levels were slightly negatively correlated with gestational and corrected gestational ages. FT3 significantly differed according to corrected gestational age (29–33 weeks vs 34–38 weeks); however, the difference was smaller than the reference change value (RCV) for the FT3 test. Thus, we combined the FT3 reference intervals into a single reference interval: 2.65–4.93 pmol/L (29–38 weeks). The reference intervals of FT4 and TSH were 11.20–24.97 pmol/L (29–38 weeks) and 1.01–10.14 mIU/L (29–38 weeks), respectively. Conclusions Unlike those of full-term infants or adults, the reference intervals established in this study are applicable in premature infants. These results highlight the importance and complexity of establishing instrument-specific thyroid hormone reference intervals for preterm infants.

The aim of the study was to evaluate the role of human epididymal secretory protein (HE4), cancer antigen 125 (CA125), and the Risk of Ovarian Malignancy Algorithm (ROMA) in diagnosing benign pelvic masses in premenopausal women.Serum was collected from 391 premenopausal women with benign pelvic mass prior to surgery and from 45 healthy individuals. Serum HE4 and CA125 levels and ROMA scores were evaluated separately.Among the 391 women with benign pelvic mass, 2.3% (9/391) had elevated HE4 levels (70 pmol/L), while 37.1% (145/391) had elevated CA125 levels (35 U/mL) (p0001). Endometriosis provided false-positive results for CA125 levels in more than half of the cases but resulted in no significant change for HE4 level. In 13 gravid women with a mass, 30.8% (4/13) and 38.5% (5/13) had elevated HE4 and CA125 levels, respectively; however, the difference was not significant (p0.05). Moreover, serum levels and patient percentages for CA125 elevation significantly increased with increase in mass diameter, whereas those for HE4 did not.CA125 elevation showed random results for benign pelvic masses, while HE4 elevation showed a higher specificity. Thus, serum HE4 testing is a better approach than CA125 testing for diagnosing benign pelvic masses in premenopausal women.

The present study aimed to compare the effect of conservative pharmacotherapy (CP) and staged percutaneous coronary intervention (SPCI) on significant non-culprit vessels in patients with ST-segment elevation myocardial infarction (STEMI). A total of 266 male and 40 female patients were divided into two groups following their first successful PCI treatment: i) Patients in the complete revascularization (CR) group undergoing SPCI; and ii) patients in the CP group undergoing CP. Follow-up data were collected at 180 or 360 days after surgery to compare the rates of major adverse cardiovascular events (MACE), recurrent myocardial infarction, recurrent angina pectoris and MACE-free survival rates between the two groups. The rate of MACE in the CP group was higher compared with that in the CR group at the 360-day follow-up (6.1 vs. 12.7%; P=0.05), and the same was reflected in the rate of recurrent myocardial infarction (10.1 vs. 4.1%; P=0.04). The rate of recurrent angina pectoris in the CP group was significantly higher compared with that in CR group at the 180-day (13.9 vs. 5.4%; P=0.012) and 360-day follow-up (18.4 vs. 8.1%; P=0.009). The MACE-free survival rate of patients was significantly higher in the CR group compared with that in the CP group at the 360-day follow-up (93.9% vs. 87.3%, P

Background: The no-reflow phenomenon during primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI) can lead to poor outcomes. It has been shown that the monocytes may be involved in the pathogenesis of coronary artery disease and associated with high risk of myocardial infarction. Aim: To assess the relation between admission monocyte count and angiographic no-reflow after pPCI. Methods: A total of 236 patients with acute STEMI, who underwent pPCI, were enrolled. The patients were divided into two groups (no-reflow and normal reflow) based on post-pPCI Thrombolysis in Myocardial Infarction (TIMI) flow grade. No reflow was defined as TIMI flow grades ≤ 2, and normal reflow was defined as TIMI 3 flow grade. The monocyte count and other laboratory parameters were measured on admission before pPCI. Results: There were 43 (18.2%) patients in the no-reflow group and 193 (81.8%) patients in the normal-reflow group. Patients with no-reflow had significantly higher admission monocyte count (0.76 ± 0.48 × 109/L vs. 0.55 ± 0.29 × 109/L, p = 0.004). Also, white blood cell and neutrophil counts were significantly higher while haemoglobin was significantly lower in the no-reflow group. In multivariate analysis, monocyte count remained an independent predictor of angiographic no-reflow phenomenon (odds ratio [OR] 2.665, 95% confidence interwal [CI] 1.102–6.445, p = 0.030) together with low haemoglobin concentration (OR 0.978, 95% CI 0.961–0.995, p = 0.013). Conclusions: Monocyte count on admission and low haemoglobin concentration were independent clinical predictors of no-reflow following pPCI in patients with STEMI. Our findings suggest that admission monocyte count may be available for early risk stratification of no-reflow after pPCI and might allow the improvement of strategies to prevent this phenomenon.

The no-reflow phenomenon during primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI) can lead to poor outcomes. Increased neutrophil counts have been associated with an increased risk of adverse clinical events after acute myocardial infarction (AMI). The aim of this study was to assess the relation between admission neutrophil counts and angiographic no-reflow after PPCI.A total of 217 patients with acute STEMI who underwent PPCI, were enrolled. The patients were divided into two groups: no-reflow and normal-reflow. The neutrophil counts and other laboratory parameters were measured on admission before PPCI.There were 41 patients (18.9%) in the no-reflow group and 176 patients in the normal-reflow group. Patients with no-reflow were older (68.0 ± 11.7 years vs 60.7 ± 13.2 years, P = 0.019) and had significantly higher admission neutrophil counts (9.02 ± 3.97 × 109/L vs 7.57 ± 2.82 × 109/L, P = 0.007). Also, high-sensitivity C-reactive protein (hsCRP), white blood counts, monocyte counts were significantly higher while haemoglobin values were significantly lower in the no-reflow group. In multivariate analysis, neutrophil counts remained a strong independent predictor of angiographic no-reflow (odds ratio 1,200, 95% confidence interval 1.073-1.342, P = 0.001) together with age (odds ratio 1.041, 95% confidence interval 1.012-1.071, P = 0.005).Neutrophil counts on admission and age were independent clinical predictors of no-reflow following primary PCI in patients with STEMI. Our findings suggest that admission neutrophil counts may be available for early risk stratification of no-reflow after primary PCI and might allow the improvement of strategies to prevent this phenomenon.

Background Thyroid-stimulating hormone (TSH) levels are an important parameter in screening for congenital hypothyroidism (CH). This study aimed to analyze the effects of birth weight, gestational age, and delivery mode on the incidence of neonatal CH. Methods A retrospective cohort study of neonates born in 2015 at a maternity hospital in Xiamen, China and their mothers was conducted. Differences in TSH levels, CH positivity at baseline, and the incidence of CH according to gestational age, birth weight, and delivery mode were assessed using matched neonatal and maternal data. Results Of the 15,615 enrolled neonates, 150 had positive CH screening results at baseline and nine had confirmed CH. Premature and low-birth-weight neonates had a significantly higher incidence of CH and lower TSH levels when compared to full-term neonates and normal-to-high birth weight neonates, respectively. Neonates delivered vaginally had significantly lower TSH levels and a reduced incidence of baseline CH positivity; cesarean section delivery (odds ratio [OR] = 2.06, p = 0.006) and a maternal TSH level >2.5 mIU/L (OR = 2.37, p = 0.002) were risk factors for CH positivity at baseline. Conclusions In this study, the incidence of CH in neonates was associated with gestational age and birth weight. Neonatal baseline CH positivity was positively associated with cesarean delivery and an early-pregnancy maternal TSH level >2.5 mIU/L.

Acute heart failure (AHF) is a major public health issue due to its high incidence and poor prognosis; thus, efficient and timely diagnosis is critical for improving the prognosis and lowering the mortality rate. Amino-terminal pro-brain natriuretic peptide (NT-proBNP) is widely used in the diagnosis of AHF; however, its efficacy is controversial in diagnosing AHF with renal insufficiency. There were numerous studies reporting the association of adiponectin (ADPN) and heart diseases. Therefore, the present study aimed to investigate whether ADPN is helpful in identifying AHF with renal insufficiency. A total of 407 participants (218 AHF patients and 189 controls) were enrolled into the current study. The plasma levels of ADPN and NT-proBNP were measured using a sandwich enzyme-linked immunosorbent assay and an electrochemiluminescence immunoassay, respectively. In addition, these levels were compared among the various New York Health Association classes, as well as the ischemic and non-ischemic AHF cases. The correlation between the two biomarkers and the renal function was analyzed by Spearman's correlation, while the diagnostic efficiency of ADPN and NT-proBNP was evaluated in AHF patients with and without renal insufficiency. The results revealed that NT-proBNP exhibited a higher diagnostic efficiency as compared with ADPN in patients without renal insufficiency [area under the receiver operating characteristic curve (AUC), 0.905 vs. 0.775]. By contrast, the ADPN presented a better diagnostic value in comparison with NT-proBNP in AHF with renal insufficiency (AUC, 0.872 vs. 0.828). Therefore, a combination of these two biomarkers may provide an excellent efficacy in the diagnosis of AHF with renal insufficiency (AUC, 0.904; sensitivity, 71.2%; specificity, 98.3%). In conclusion, ADPN is a valuable biomarker for diagnosing AHF, particularly in patients with impaired renal function.

Background: The intracoronary high-thrombus burden during the primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction (STEMI) can lead to poor outcomes. Monocytes have been described to play an important role in thrombotic disorders. Objectives: This study aimed to investigate the relationship between admission monocyte count and angiographic intracoronary thrombus burden in patients receiving primary percutaneous coronary intervention (PPCI). Methods: A total of 273 patients with acute STEMI who underwent PPCI were enrolled. The patients were divided into two groups according to the thrombolysis in myocardial infarction (TIMI) thrombus grade: low-thrombus burden group with a grade of 0-2 and high-thrombus burden group with a grade of 3-4. The monocyte count and other laboratory parameters were measured on admission before PPCI. P-value < 0.05 was considered significant. Results: There were 95 patients (34.8%) in the high-thrombus burden group, and 178 patients (65.2%) in the low-thrombus burden group. Patients with high-thrombus burden had significantly higher admission monocyte count (0.61 ± 0.29×109/L vs. 0.53 ± 0.24×109/L, p = 0.021). In multivariate analysis, monocyte count was the independent predictor of angiographic high-thrombus burden (odds ratio 3.107, 95% confidence interval [CI] 1.199-7.052, p = 0.020). For the prediction of angiographic high-thrombus burden, admission monocyte count at a cut-off value of 0.48×109/L yielded 0.59 ROC-AUC (71.9% sensitivity, 46.9% specificity). Conclusions: Monocyte count on admission was an independent clinical predictor of high-thrombus burden in patients with STEMI undergoing PPCI. Our findings suggest that admission monocyte count may be available for early risk stratification of high-thrombus burden in acute STEMI patients and might allow the optimization of antithrombotic therapy to improve the outcomes of PPCI.

Objectives To access the biocompatibility, effectiveness, and safety of biodegradable magnesium (Mg) alloy stent (BMAS) in the coronary artery and femoral artery. Background Atherosclerosis is a lesion of cardiovascular system, including the diseases in heart and blood vessels. Methods The aluminum (Al) and zinc (Zn)-based BMAS was designed by cold drawing methods. Forty healthy immunized mongrel dogs were randomly divided into 8 groups. Five dogs who have not been treated with stent were included in control group. The other dogs were implanted with an absorbable magnesium (Mg) alloy in the coronary and/or femoral artery, and their artery angiography were observed at 7 time points (1, 3, 5, 7, 14, 21, and 28 days; n = 5) follow-up. Dogs from each cohort were sacrificed following angiography for pathology assessment. The histological response including inflammatory response, thrombosis, and intimal hyperplasia were analyzed by hematoxylin-eosin staining. Lumen area (La), intimal hyperplasia area (IHa), and the ratio of IHa were calculated by image analysis software. Results The thin-walled BMAS were designed and produced by cold-drawing technology. Fifty-one devices were implanted into coronary artery of 35 dogs successfully. During the follow-up days, the angiography of coronary artery and femoral artery had confirmed that the lumen was clear and there were no elastic recoil and thrombosis. The stents were completely disappeared at 7 days after implantation. Moderate intimal hyperplasia was found at 14 days after implantation. Conclusion The BMAS stent proved to be of good biocompatibility, safety, and effectiveness. (J Interven Cardiol 2015;XXXX:XX–XX)

The automatic anti-cyclic citrullinated peptide (anti-CCP) antibodies assay offered great advantages over traditional methods in terms of improved precision, reliability, technical simplicity, short turnaround time and high-speed throughput. In this study, we evaluated the main technical performance and diagnostic accuracy of the first automatic anti-CCP assay approved in China.The study comprised 106 rheumatoid arthritis (RA) patients, 203 non-RA rheumatic disease controls and 46 healthy persons. Anti-CCP, rheumatoid factor (RF), α1-acid glycoprotein, C-reactive protein and erythrocyte sedimentation rate were measured and compared. The precision, reference intervals for Chinese population and cut-off value for RA diagnosis, as well as the suitable diluent for anti-CCP were assessed. The positive rate and score of anti-CCP were compared with RF and acute-phase reactants, according to the new RA criteria.Within- and between-run imprecision, expressed as the coefficient of variation, were 0.47-1.36% and 1.15-2.63%, respectively. Upper 95% reference limit of anti-CCP in healthy Chinese was 8.8 U/mL. The area under curve of the receiver operating characteristic(ROC) for anti-CCP and RF were 0.882 (95% CI 0.833-0.930) and 0.844 (95% CI 0.792-0.897), respectively. Based on the cut-off value set by ROC, compared to RF, anti-CCP had higher sensitivity (96.8% vs. 78.3%) and specificity (90.9% vs. 70.7%). With 17 U/mL set as the optimal cut-off for anti-CCP, the total positivity of anti-CCP was comparable to that of RF (76.4% vs. 75.5%), but the high-positivity rate of anti-CCP was significantly higher (74.5% vs. 62.3%, p0.005).Our results confirm anti-CCP as a more sensitive and specific marker than RF for the diagnosis of RA. The diagnostic performance of the Elecsys anti-CCP assay makes it a useful adjunct to clinical practice in the Chinese population.

BACKGROUND To investigate the practical value of individual and combined testing of plasma levels of YKL-40, CEA, and CA199 for auxiliary diagnosis and detection of recurrence of colorectal cancer. METHODS ELISA and ECLIA were used to evaluate levels of YKL-40, CEA, and CA199 in 120 colorectal cancer patients (56 initial-diagnosis, 42 post-operative, and 22 recurrent cases). Forty-three patients with benign colorectal disease and 36 healthy patients were enrolled as controls. The relationship between YKL-40 and clinical indicators of tumor pathology was analyzed. The positive rate and diagnostic efficacy of single and combined YKL-40, CEA, and CA199 testing were assessed in patients with colorectal cancer. RESULTS Plasma YKL-40 in the cancer group was significantly higher than in the benign control and healthy control group, and the mean values were 145.4 ng/mL, 107.7 ng/mL, and 51.3 ng/mL (p < 0.05), respectively. With 72 ng/mL as the diagnostic threshold, the sensitivity and specificity of YKL-40 in colorectal cancer diagnosis were found to be 73.2% and 66.7%, respectively. Early-stage colorectal cancer patients showed a YKL-40 positive rate (73%) significantly higher than those of CEA and CA199 (50% and 32%, respectively; p < 0.05). When YKL-40 testing was combined with CEA or CA199, the positive rate increased to 82.1% and 80.3%, respectively. Through ROC curve analysis of the post-operative recurrent group against the non-recurrent group, the areas under the curve for YKL-40, CEA, and CA199 were found to be 0.907, 0.714, and 0.759, respectively. Based on the Dukes classification, the mean YKL-40 value for stages A/B, C, and D were 120.1 ng/mL, 131.7 ng/mL, and 226.8 ng/mL (p = 0.008), respectively. The plasma YKL-40 level gradually increased as the disease progressed. Lower degrees of tumor differentiation were correlated with higher YKL-40 levels. The mean YKL-40 values of high, medium, and low tumor differentiation groups were 96.8 ng/mL, 127.5 ng/mL, and 225.7 ng/mL (p = 0.004), respectively. CONCLUSIONS The benefits of using YKL-40 testing are higher than CEA and CA199 for the monitoring of colorectal cancer recurrence. Combined testing of both YKL-40 and CEA was found to be optimal for auxiliary diagnosis of colorectal cancer. Plasma YKL-40 was found to be suitable for auxiliary diagnosis of colorectal cancer.

The aim of this study was to investigate the application of adenosine stress echocardiography (ASE) in the prognosis of acute myocardial infarction (AMI) following percutaneous coronary intervention (PCI). A total of 79 patients with AMI who underwent PCI were selected for the study. ASE testing was performed within one week following the PCI. Subsequent to the ASE, the patients with ≥5% increases in the left ventricular ejection fraction (LVEF) levels were included in the improved LVEF group, while patients with

There are no highly sensitive and specific minimally invasive biomarkers for hepatocellular carcinoma (HCC) to date. The objective of this study was to identify serum microRNAs (miRNAs) as potential HCC biomarkers.Using miRCURY LNA™ microRNA arrays, the levels of circulating miRNAs in the serum of patients with HCC were compared and controls were matched. Then 253 subjects (112 HCC, 85 chronic hepatitis B [CHB], and 56 healthy controls) were recruited and 12 serum miRNAs were compared by quantitative real-time polymerase chain reaction (qRT-PCR). It was followed by the comparison of serum miRNA concentrations before and after the surgical resection in HCC group.Median levels of miR-483-5p and miR-500a were higher in HCC patients than in patients with CHB and in healthy controls (p 0.0001), but there were no differences between CHB patients and healthy controls (p 0.05) and miR-483-5p levels were significantly reduced in serum samples obtained 30 days after surgical resection (p 0.0001). The area under receiver operating characteristic curves of miR-483-5p and miR-500a was 74% (cutoff [Ct] value = 2.824, sensitivity = 74%, and specificity = 66%) and 66% (Ct value = 1.830, sensitivity = 74%, and specificity = 51%) for the prediction of HCC, respectively. In detecting HCC, combining α-fetoprotein (AFP) and serum miR-483-5p (sensitivity = 81% and specificity = 83%) was better than AFP alone (sensitivity = 78%, specificity = 70%).Our observations suggest that serum miR-483-5p and miR-500a might serve as novel, noninvasive biomarkers for HCC. Serum miR-483-5p might complement AFP in detecting HCC.
