Abstract Background: LIM and SH3 protein 1 (LASP-1) has been demonstrated to be overexpression in several types of cancers. The aim of this study was to verify the serum level of LASP-1 and investigate its diagnostic value in cholangiocarcinoma (CCA) patients.Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression level of LASP-1 in CCA patients and healthy controls. The correlation of LASP-1 expression with clinicopathological characteristic of CCA patients was analyzed via Chi-square test. Receiver operating characteristic (ROC) curve was built to evaluate the diagnostic value of serum LASP-1 in CCA.Results: Serum levels of LASP-1 were upregulated in CCA compared with healthy controls (P<0.01). And the serum level and tissue level of LASP-1 mRNA exhibited significant correlation (R=0.454, P=0.000). Serum expression of LASP-1 was closely associated with lymph node metastasis (P=0.018) and TNM stage (P=0.021). ROC curve analysis revealed that serum LASP-1 was of great value in differentiating CCA patients from healthy individuals. The area under the ROC curve (AUC) value was 0.879 corresponding with a sensitivity of 81.9% and a specificity of 79.6%.Conclusions: Serum LASP-1 might be an useful diagnostic biomarker for CCA.

Abstract Background Period 1 (Per1) had been reported to be involved in the tumorigenesis and progression of human cancers. However, the clinical significance of Per1 in cholangiocarcinoma (CCA) was unclear. The purpose of this study was to explore the diagnostic value of serum Per1 in CCA patients. Methods Serum levels of Per1 in CCA patients and healthy individuals were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was used to evaluate the relationship between Per1 expression and clinical characteristics of patients. The diagnostic value of Per1 in CCA was estimated by establishing a receiver operating characteristic (ROC) curve. Results Serum Per1 level was significantly down-regulated in CCA patients compared to that in healthy controls (P < 0.001). Moreover, the decreased expression of Per1 was closely associated with poor histological differentiation (P = 0.040), advanced TNM stage (P = 0.035) and positive lymph node metastasis (P = 0.007). ROC curve indicated that the area under the curve (AUC) was 0.863 with a sensitivity of 88.1% and a specificity of 72.1%, revealing the high diagnostic value of serum Per1 in CCA. Conclusions Per1 is down-regulated in CCA and negatively correlated with tumor progression. Serum Per1 may be a potential biomarker for early screening of CCA.

Background: Leprosy is a chronic infectious disease primarily affecting the peripheral nervous system and skin. Multibacillary leprosy is associated with nerve damage which could contribute to myelin alteration. As ceramide is a constituent of myelin sheath, the present study aimed to compare anti-ceramide antibody titre in paucibacillary and multibacillary leprosy patients with controls. Methodology: Serum levels of anti-ceramide antibody were measured using enzyme-linked immunosorbent assays (ELISA) in 50 leprosy patients (25 paucibacillary and 25 multibacillary) and 25 healthy controls. Results were reported in OD units as mean ± SD and analyzed by Chi square test (significance at p < 0.05). Results: Patients suffering from multibacillary leprosy had significantly higher anti-ceramide antibody serum levels compared to paucibacillary leprosy patients and healthy controls (p < 0.005). Conclusions: Since nerve damage is the most debilitating effect of leprosy, the search for a serum marker for assessing nerve damage is required in countries where leprosy is still widespread. In multibacillary leprosy patients, the role of anti-ceramide antibody as a marker for nerve damage should be explored.

Background This study aimed to investigate the diagnostic value of prealbumin-to-fibrinogen ratio (PFR) and albumin-to-fibrinogen ratio (AFR) alone or in combination in Helicobacter pylori-negative gastric cancer (Hp-NGC) patients. Methods This study included 171 healthy controls, 180 Hp-NGC patients, and 215 Helicobacter pylori-negative chronic gastritis (HpN) patients. We compared the differences of various indicators and pathological characteristics between groups with Mann–Whitney U test and Chi-square test. The diagnostic value of PFR and AFR alone or in combination for Hp-NGC patients was assessed by the receiver operating characteristic (ROC) curve. Results PFR and AFR were related to the progression and clinicopathological characteristics of Hp-NGC. As the disease progressed, PFR and AFR values gradually decreased and were negatively related to the tumor size and depth of invasion. In addition, the area under the curves (AUCs) that resulted from combining PFR and AFR to distinguish Hp-NGC patients from healthy controls and HpN patients were 0.908 and 0.654, respectively. When combined with PFR and AFR in the differential diagnosis of tumors with a maximum diameter ≥ 5 cm and the T3 + T4 stage, the AUCs were 0.949 and 0.922; the sensitivity was 86.32% and 80.74%; and the specificity was 94.74% and 92.98%, respectively. Conclusions PFR and AFR may be used as diagnostic biomarkers for Hp-NGC. The combination of PFR and AFR was more valuable than each indicator alone in the diagnosis of Hp-NGC.

Background. Dyspnea could be caused by various reason, one of which is the presence of cardiac abnormality. Physical examination sometimes difficult to distinguish breath caused by heart abnormalities, especially small children, so we need another way to find out.Objective. To evaluate whether the examination of NT-proBNP levels can be used as a screening tool to diagnose cardiac abnormality in children presenting with dyspnea.Methods. A Cross sectional study was conducted from August to October 2015 on pediatric patients aged 1 month to 18 years presenting with dyspnea in pediatric ward Mohammad Hoesin Hospital Palembang. All subjects performed blood sampling for NT-proBNP examination and echocardiography to assess the presence of cardiac abnormalities. The diagnostic value analyzed by ROC curve, and determined the optimal cut-off point, sensitivity and specificity. Result. We obtained 58 subjects with median age 9.5 (1-180) months, consisted of 39 subjects with cardiac abnormalities and 19 subjects without cardiac abnormality. There is a significant difference (p = 0.002) of NT-proBNP levels in both groups with a median  1,775 (189-9,000) pg/ml vs 759 (245-9,000) pg/ml. In ROC curve analysis, AUC value was 0.75, and at the optimal cut-off point 1,235 pg/ml, sensitivity was 74.4% and specificity was 73.7%.Conclusion. The level of NT-proBNP can be used to diagnose cardiac abnormalities in children presenting with dyspnea.
