refore, careful prenatal and antenatal follow-up need to be strengthened with due emphasis for maternal iron assessment.BACKGROUND Colon cancer is one of the most common and has the highest mortality rate in the world. MicroRNAs (miRNAs) as potential biomarkers play crucial roles in diagnosis, prognosis, and drug-response prediction of colon cancer. METHODS In this study, we collected miRNA expression data from the Broad GDAC Firehose and screened specific miRNA-gene pairs after treatment with 5-fluorouracil treatment and used COAD analysis to study the association of miRNAs and inhibitor of the inhibitory genes. Potential drug-related miRNAs were further extracted via hypergeometric testing. RESULTS The results showed that 13,651 miRNA-gene pairs were retrieved, including 242 miRNAs and 5,179 genes. The association between miRNAs and the inhibitor of inhibitory genes DPYD, TYMS, UNG was indicated. We further extracted 4 potential drug-related miRNAs, including hsa-mir-551a, hsa-mir-144, hsa-mir-519b, hsa-mir-506. The miRNA-gene pairs associated with 5-fluorouracil exhibit better prognosis in patients with CRC. CONCLUSIONS We expected that up-regulation of hsa-mir-551a, hsa-mir-144, and hsa-mir-506 and down-regulation of hsa-mir-519b would exhibit better prognosis. The findings would underpin the fundamental hypothesis of mi-RNAs being prognostic signal biomarkers in therapy of 5-fluorouracil in CRC.BACKGROUND The current study aims to evaluate the correlation between peripheral blood miR-148a-3p level in patients with liver injury after hepatectomy under general anesthesia with propofol, thereby evaluating whether circulating miR-148a-3p can be used as a biomarker of liver injury after hepatectomy. METHODS One hundred one patients who underwent hepatectomy at the Fourth Hospital of Xi'an were selected. On the first day after operation, peripheral blood was taken to determine the level of miR-148a-3p in peripheral blood. The correlation between circulating miR-148a-3p and liver injury after operation was analyzed using Pearson's correlation assay. RESULTS First, our data showed that the level of miR-148a-3p was increased in the peripheral blood of patients after hepatectomy. The amount of bleeding was significantly correlated with the increase of ALT, AST, and miR-148a-3p. Moreover, the level of miR-148a-3p was significantly correlated with alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Further analysis showed that intraoperative propofol dosage was correlated with ALT, AST, and miR-148a-3p after hepatectomy. CONCLUSIONS MiR-148a-3p may be sensitive to ischemic and traumatic liver injury and may be a marker of liver injury after hepatectomy under general anesthesia with propofol.BACKGROUND Chronic myeloid leukemia (CML) is a disease resulting from BCR-ABL gene fusion. It is possible to monitor treatment by molecular testing for BCR-ABL. The lymphocyte-to-monocyte ratio (LMR) is a commonly used marker associated with prognosis in various neoplasms. This study was performed to evaluate the relevance of absolute lymphocyte count (ALC), absolute monocyte count (AMC), and LMR in predicting molecular response status in patients with chronic phase CML. METHODS Samples submitted to our hematology laboratory for BCR-ABL testing between April 2012 and October 2018 were retrospectively reviewed. Concurrent hemogram testing together with the results of quantitative reverse transcriptase-polymerase chain reaction were noted. Data were grouped according to molecular response status and the ALC, AMC, and LMR were compared among patient groups. RESULTS A total of 224 samples from 95 patients were included in the study. Analysis revealed differences between groups when newly diagnosed patients were compared with patients undergoing treatment, regardless of response status. However, analyzing the groups according to molecular response status failed to reveal differences in ALC, AMC, or LMR. CONCLUSIONS ALC, AMC, and LMR are not potential biomarkers for predicting molecular response status in patients with chronic phase CML.BACKGROUND Campylobacter spp. is one of the leading causes of bacterial foodborne infections worldwide. In this study, we aimed to investigate the genetic diversity of 341 Campylobacter strains isolated in Turkey. METHODS Campylobacter spp. was identified by phenotypical methods and PCR. Species level identification was carried out by the hippurate hydrolysis test and PCR. C. jejuni and C. coli strains were typed by using flaA-RFLP and PFGE. RESULTS Of 341 strains, 300 (88%), 37 (10.8%), and four were identified as C. jejuni, C. coli, and non-jejuni/non-coli, respectively. The hippurate hydrolysis test misidentified 12% of 341 strains. The typeabilities of flaA-RFLP and PFGE were 100% for C. coli, whereas those of flaA-RFLP and PFGE for C. jejuni were 99.3% and 99%, respectively. The discriminatory power of the combination of PFGE and flaA-RFLP was determined to be higher than either method alone for both C. jejuni and C. coli. Both of the strains were so diverse that 80% and 64% of C. jejuni and C. coli genotypes included only one strain, respectively. In two patients, Campylobacter strains that were isolated from the first stool samples were C. jejuni where as those isolated from the second samples, collected eight and 20 days after the collection of the first samples, were C. coli. C. jejuni strains that were recovered from two different stool samples of two patients, collected 1 - 2 days apart, were found to be genetically different. CONCLUSIONS Species identification of Campylobacter strains should be done using molecular methods. Combination of two methods is prerequisite for increasing the accuracy of molecular typing. Mixed or subsequent infection by different Campylobacter species and C. jejuni of different genotypes should not be underestimated.BACKGROUND The case concerns a 30-year-old woman in the 24th week of pregnancy presenting to the medical emergency room with fever and abdominal pain. Urine sediment microscopy revealed the presence of unknown needle-shaped crystals. METHODS Crystals identification was performed by Fourier-Transform Infrared Spectroscopy coupled to Attenuated Total Reflectance (FTIR-ATR). RESULTS Amoxicillin crystals were verified with semiquantitative results of 87.7%. CONCLUSIONS Drug-induced crystalluria is a frequent finding in urine examination and it may be asymptomatic. FTIR spectroscopy is a rapid and specific tool in identification of crystals and could be useful supporting renal disease diagnosis and monitoring drug therapy.BACKGROUND Cyclosporine injection is usually applied in allogeneic hematopoietic stem cell transplantation (Allo-HSCT) during induction phase. Anaphylaxis to cyclosporine injection is rare and how to deal with this issue in clinical practice is intractable. METHODS We report a Chinese male patient with aplastic anemia who underwent allogeneic bone marrow transplantation (BMT) from his brother where HLA totally matched (10/10). Cyclosporine at a dose of 3 mg/kg was started by continuous infusion over 24 hours on day -1 of BMT and the patient showed sever anaphylaxis symptoms. He was then given oral capsules of cyclosporine (Sandimmun) at a conversion ratio 21. No further anaphylactic reaction was observed. The BM cells were successfully engrafted without causing severe GVHD. Moreover, frequent TDM monitoring as well as CYP3A4/CYP3A5/MDR1 genotyping were given so as to tailor the oral dosage of cyclosporine individually and prevent the adverse reaction between cyclosporine and posaconazole. RESULTS The patient carried CYP3A5*3 GG genotype and the concentration of cyclosporine remained steady in the period of conversion and combination of cyclosporine and posaconazole. Consequently, the patient reported no allergy after conversion to oral cyclosporine. CONCLUSIONS Polyoxyethylated castor oil that is contained in cyclosporine may be the main allergen. Changing to oral capsules that do not contain this medicinal excipient instead of cyclosporine injection would no longer cause an allergic reaction. Rational use of immunosuppressants and prophylaxis antibiotics may need close cooperation between physicians and pharmacists to avoid side effects and harmful interactions.BACKGROUND Vitamin B12 is very important for the human body. Early diagnosis of vitamin B12 deficiency is essential because it is associated with many problems such as fatigue, lethargy, depression, poor memory, breathlessness, headaches, pale skin, mania, psychosis, etc. Most of the vitamin B12 molecules in serum bind to specific proteins as a complex; so, although researchers have developed some sensitive methods to quantify vitamin B12, few can be used for human serum detection of vitamin B12 because of disturbed releasing process. In this study, we are aiming to develop a rapid and accurate chemiluminescence immunoassay (CLIA) for human serum testing. METHODS In this study, we studied and optimized labelling of biotin molecules to vitamin B12 binding protein which had been extracted from hog gastric mucus, labelling of vitamin B12 molecules to horse radish peroxidase (HRP), releasing of vitamin B12 from its bound state in serum, concentrations of reagents, and incubation times. RESULTS The developed method shows good performance and thermo-stability. The limit of detection (LOD) is 41 pg/mL, the recovery rate is 90.7% - 107.4%. The intra-assay CV is 4.4% - 8.0% and the inter-assay CV is 4.5% - 12.1%. Cross reactivity (CR) values are 49.4% for hydroxocobalamin and lower than 0.1% for vitamin B1, B2, B3, B9, and C. The method comparison results show that the correlation coefficient (R2) is 0.91, with a slight negative bias of -4.1% [95% limits of agreement (± 1.96 SD); -39.6% to 31.6%]. CONCLUSIONS The developed method shows high sensitivity and specificity and good correlation using a Beckman Coulter instrument while the whole test needs only 40 minutes. 1-Methylnicotinamide ic50 It can fully satisfy the very busy clinical labs.BACKGROUND Rapid and accurate diagnosis of mucopolysaccharidoses (MPS) is still a challenge due to poor access to screening and diagnostic methods and to their extensive clinical heterogeneity. The aim of this work is to perform laboratory biochemical testing for confirming the diagnosis of mucopolysaccharidosis (MPS) for the first time in Morocco. METHODS Over a period of twelve months, 88 patients suspected of having Mucopolysaccharidosis (MPS) were referred to our laboratory. Quantitative and qualitative urine glycosaminoglycan (GAG) analyses were performed, and enzyme activity was assayed on dried blood spots (DBS) using fluorogenic substrates. Enzyme activity was measured as normal, low, or undetectable. RESULTS Of the 88 patients studied, 26 were confirmed to have MPS; 19 MPS I (Hurler syndrome; OMIM #607014/Hurler-Scheie syndrome; OMIM #607015), 2 MPS II (Hunter syndrome; OMIM #309900), 2 MPS IIIA (Sanfilippo syndrome; OMIM #252900), 1 MPS IIIB (Sanfilippo syndrome; OMIM #252920) and 2 MPS VI (Maroteaux-Lamy syndrome; OMIM #253200). Parental consanguinity was present in 80.76% of cases. Qualitative urinary glycosaminoglycan (uGAGs) assays showed abnormal profiles in 31 cases, and further quantitative urinary GAG evaluation and Thin Layer Chromatography (TLC) provided important additional information about the likely MPS diagnosis. The final diagnosis was confirmed by specific enzyme activity analysis in the DBS samples. CONCLUSIONS The present study shows that the adoption of combined urinary substrate analysis and enzyme assays using dried blood spots can facilitate such diagnosis, offer an important tool for an appropriate supporting care, and a specific therapy, when available.
