6.Progress of SF3B1 gene mutation and hematological malignancies
International Journal of Pediatrics 2014;(4):354-356,357
The SF3B1 gene encodes subunit 1 of the splicing factor 3b,which is a core component of the U2 small nuclear ribonucleoprotein and plays an important role in the process of RNA splicing. Abnormal splicing caused by SF3B1 mutations are associated with hematological malignancies,particularly with myelodys-plastic syndrome,refractory anemia with ring sideroblasts associated with marked thrombocytosis and chronic lymphocytic leukemia( CLL) . In myelodysplastic syndrome and refractory anemia with ring sideroblasts associat-ed with marked thrombocytosis,SF3B1 mutations are bond up with favorable prognosis and strongly with ring sideroblasts. But in CLL,SF3B1 mutations are factors of poor prognosis.

Chinese Journal of Postgraduates of Medicine 2017;40(7):597-600
Objective Based on the 2012 Atlanta classification criteria, to study the value of C-reactive protein (CRP) and procalcitonin (PCT) in the early forecasting acute pancreatitis (AP). Methods Eighty-three patients with AP were selected. The patients were divided into mild AP (MAP) group (39 cases), moderately severe AP (MSAP) group (31 cases) and severe AP (SAP) group (13 cases) according to the 2012 Atlanta classification criteria. Twenty-seven healthy people were selected as control group. The levels of serum CRP and PCT were measured. The predictive value of serum CRP and PCT levels for SAP, infectious pancreatic necrosis (IPN), organ failure and death risk was assessed using the area under the curve (AUC). Results The serum CRP and PCT levels in MAP group, MSAP group and SAP group were significantly higher than those in control group: (49.84 ± 12.26), (89.77 ± 22.10) and (123.69 ± 37.09) mg/L vs. (3.92 ± 1.37) mg/L, (1.15 ± 0.42), (2.44 ± 0.61) and (3.27 ± 0.96)μg/L vs. (0.41 ± 0.13)μg/L, and those in MSAP group and SAP group were significantly higher than those in MAP group, those in SAP group were significantly higher than those in MSAP group, and there were statistical differences (P<0.05). The Spearman correlation analysis result showed that AP severity was positively correlated with serum CRP and PCT levels (r = 0.652 and 0.714, P<0.05). The accuracy of serum CRP level for forecasting SAP and IPN was medium (AUC = 0.73 and 0.76), and for forecasting organ failure accuracy was low (AUC = 0.67). Serum CRP showed no significance in forecasting death risk (AUC = 0.46). The accuracy of serum PCT level for forecasting SAP, IPN and death risk accuracy was medium (AUC = 0.71, 0.86 and 0.80), and for forecasting organ failure accuracy was low (AUC =0.64). Conclusions Based on the 2012 Atlanta classification criteria, the accuracy of serum CRP level for forecasting SAP is higher than that of serum PCT level, the accuracy of serum PCT level for forecasting IPN and death risk is higher than that of serum CRP level, and accuracy of serum CRP and PCT levels for forecasting organ failure are low.
8.Advances in the application and detection of small dense low-density lipoprotein
Chinese Journal of Laboratory Medicine 2017;40(6):417-420
Regular checking blood lipids may be served as the important approach for the risk assessment and prevention of the atherosclerotic cardiovascular disease (ASCVD). It has been emphasized by several dyslipidemia management guidelines that the low density lipoprotein cholesterol (LDL-C) was the primary intervention target for prevention of ASCVD risk. Recent studies have demonstrated that small dense low density lipoprotein (sdLDL) or sdLDL cholesterol (sdLDL-C) levels as the biomarker for the prediction and risk assessment of ASCVD may be more sensitive than LDL-C. The isolation and detection methods of sdLDL or sdLDL-C were developed from the traditional ultracentrifugation or gel electrophoresis to the efficient, fast, accurate automated processing system. The continuous advances and popularization in analytical techniques of LDL subcomponents provided new methods and ideas for their application in the risk assessment and prevention of ASCVD.
