Objective To establish a rapid, accurate and low-cost screening method for the detection of calreticulin (CALR) mutations in myeloproliferative neoplasms (MPN).Methods Seventy cases diagnosed with MPN were collected from 2012 to 2016. PCR combined with high resolution melting (HRM) analysis were used to screen the CALR mutations, and Sanger sequencing and T-A sequencing were applied to verify the HRM positive samples. CALR wild type DNA, type 1 and type 2 mutant DNA samples were selected and analyzed 4 times/day for 5 days to detected the CVs of Tm (melting temperature) respectively. JAK2 mutations were also analyzed in MPN patients to compare the association between JAK2 and CALR mutations.Results PCR-HRM analysis showed 7 cases (26.9%) and 5 cases (20.8%) patients with CALR mutations were screened out from 26 essential thrombocythaemia (ET) cases and 24 primary myelofibrosis (PMF) cases, but no CALR mutations were found in cases with polycythaemia vera (PV). All mutations were confirmed by direct sequencing or cloning sequencing. The CVs for HRM analysis of CALR wild type DNA, type 1 and type 2 mutant DNA samples were 1.91%,1.59% and 1.43%, respectively.There were 47 cases with JAK2 V617F and 1 case with exon12 mutation. No coexistence of JAK2 mutation and CALR mutations were found in a single sample.Conclusion PCR-HRM can be used for rapid screening of CALR mutation. Subsequent sequencing can be applied for rapid diagnosis of MPN patients in clinical practice.

AIM To observe the protective effects of mangiferin on the inflammatory injury and expression of the inflammatory factor in the cerebral tissue of spontaneously hypertensive rats and on MCP-1/CCR2 signal pathway.METHODS Forty spontaneously hypertensive rats were randomly divided into model,benazepril [10 mg/(kg · d)] and mangiferin high,middle and low dose [40,20,10 mg/(kg · d)] groups and other eight rats of same week age served as control group.After consecutive intragastric administration for eight weeks,morphology of the rats' cerebral tissue was observed;their levels of ICAM-1,IL-6 and TNF-α in cerebral tissue were determined by ELISA;their expressions of MCP-1 and CCR2 protein in brain tissue of rats were detected by immunohistochemistry and Western blot and the detection of mRNA expressions of MCP-1 and CCR2 in cerebral tissue of rats were carried out by RT-PCR.RESULTS Compared with the model group,the blood pressure of mangiferin in each dosage group decreased slightly,but there was no significant statistical difference.In the control group and the model group,there was no obvious morphological change in the cerebral tissue.The morphology of rats in the benazepril group,each dose of mangiferin group were all normal.The contents of IL-6,TNF-α,ICAM-1 and MCP1,CCR2 protein and mRNA expression were significantly decreased in the cerebral tissues of spontaneously hypertensive rats.CONCLUSION Mangiferin has obvious anti-inflammatory effects on inflammatory reaction in spontaneously hypertensive rats,its mechanism may be related to inhibiting the expression of MCP/CCR2 signaling pathway.

Objective To report a three-generation Chinese family with freckle and to make a genetic linkage analysis in this family.MethodsGenetic linkage analysis was carried out in this family using microsatellite markers distributed over chromosome 4q and 1.Two-point logarithm of odds(LOD)scores were calculated using the Linkage program package(version 5.1),and haplotype was analyzed with Cyrillic version 2.01 software.Results Freckle was inherited in an autosomal dominant pattern with a penetrance of99.9% in this family;linkage to chromosome 4q was ruled out however,supportive evidence was obtained for linkage to microsatellite markers D1S2635 and D1S2844 in chromosome 1q with a maximum LOD score of 1.50.Haplotype analysis in this family localized the locus of freckle to a 12 Mb region flanked by D1S2624 and D1S2799.Conclusions Freckle is a genetically heterogeneous disorder.The causative gene may be located in a 21.2 cM region on chromosome 1q22-24.

Objective:To investigate the status quo and influencing factors of health self-management ability of scientific and technological workers in Shanxi Province.Methods:This study was a cross-sectional study. Using the general situation questionnaire and the adult health self-management ability evaluation scale, 467 scientific and technological workers who received physical examination in the First Hospital of Shanxi Medical University from January 2022 to September 2022 were investigated by questionnaire, and their height, weight, body mass index, fasting blood glucose, blood lipids and blood uric acid were collected on the day of physical examination. Multiple linear regression analysis was used to explore the influencing factors of health self-management ability, and Pearson and Spearman correlation analysis was used to analyze the correlation between health self-management ability and examination items.Results:The total score of health self-management ability of 467 scientific and technological workers was (153.7±16.5). The results of multiple linear regression showed that the type of medical insurance, self-assessment of health status, staying up late, and sleep quality were independent influencing factors of health self-management ability ( R2=0.141, adjusted R2=0.120, F=6.771; P<0.001). Health self-management ability was positively correlated with high-density lipoprotein ( r=0.114), behavioral subscale was positively correlated with high-density lipoprotein ( r=0.107), environmental subscale was negatively correlated with uric acid ( r=-0.103), triglyceride ( r=-0.118), and positively correlated with high-density lipoprotein ( r=0.129), and cognitive subscale was negatively correlated with triglyceride ( r=-0.125), all of which were statistically significant ( P<0.05). Conclusions:The ability of health self-management of scientific and technological workers in Shanxi Province belongs to the upper middle level, which is affected by the type of medical insurance, the self-assessment of health status, staying up late, and the quality of sleep. It is suggested that the ability of health self-management of scientific and technological workers can be improved by strengthening their health beliefs, providing a more convenient working environment, reducing the frequency of staying up late, and improving their sleep quality.

Objective To investigate the clinical significance of plasma methylated Septin 9 (SEPT9)gene test for colorectal cancer(CRC).Methods Clinical data of this retrospective study were obtained from Huashan Hospital of Fudan University(2016-2017).The subjects were divided into three groups,84 patients in CRC group,50 patients with adenoma in precancerous group,and 20 cases as healthy controls.A fluorescent PCR assay was used to analyze SEPT 9 methylation in DNA extracted from plasma. Chi square test was used for statistical analysis.Results The positive incidence of SEPT9 gene methylation in plasma was 63.1%(53/84)in CRC group,significantly higher than 10%(5/50)in precancerous group (χ2=35.993, P<0.001), and undetectable in healthy group.The sensitivity of the methylated SEPT9 gene test was 63.1%(53/84), and the sensitivity of a joint detection combined with carcinoembryonic antigen(CEA)was 75%(63/84).The receiver operating characteristic curve(ROC)showed that methylated SEPT9 gene test had 0.828 in the area under the curve(AUC),higher than 0.795 in the AUC of CEA test.In CRC patients,51.4%(19/37)in the stage Ⅰ-Ⅱand 72.3%(34/47)in the stage Ⅲ-Ⅳ were positive for methylated SEPT9 gene test(χ2=3.917, P<0.05).There were no significant differences in gender,age and primary tumor site.Conclusion The SEPT9 gene methylation in plasma is helpful for early screening for CRC,and is associated with CRC progression.
