ABSTRACT
Objective:To analyse the association between triglyceride glucose (TyG) index and the number of coronary artery lesions in patients with stable coronary artery disease.Methods:It was a cross-sectional study. Patients with stable coronary artery disease who were admitted to Zhongshan Hospital, Fudan University from 1st January 2019 to 30th April 2020 for percutaneous coronary intervention (PCI) were selected. We collected general clinical information and laboratory results from the enrolled patients, then calculated the TyG index. We evaluated coronary artery lesions by coronary angiography and analysed the factors associated with the number of coronary artery lesion branches by the logistic regression model.Results:A total of 832 patients were included in this study, 641 (77.0%) were male, the age was (64.6±11.5) years. The mean TyG index was 8.78. Patients with the TyG index≥8.78 were included in the high TyG index group (411 patients), and those with the TyG index<8.78 were included in the low TyG index group (421 patients). Compared with the low TyG index group, the high TyG index group had the higher body mass index and diastolic blood pressure, more smokers and diabetes mellitus, younger age of onset of coronary heart disease (all P<0.05), and a lower proportion of patients using statins ( P=0.027). Compared with the low TyG index group, the high TyG index group had the higher levels of erythrocyte count, hemoglobin, white blood cell count, albumin, urea nitrogen, uric acid, fasting blood glucose, HbA1c, triglyceride, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, apolipoprotein E, and C-reactive protein (all P<0.05). However, the levels of high density lipoprotein, apolipoprotein A1 and apolipoprotein A were lower in the high TyG index group than those in the low TyG index group (all P<0.05). The number of coronary artery lesions in patients in the high TyG index group was 2.35±0.91, more than the low TyG index group 2.10±0.95 ( P<0.001).After adjusting for the other factors, multivariate logistic regression analysis showed that male, smoking history (smoking cessation or smoking), TyG index and troponin T levels were independently positively associated with the number of coronary artery lesions (all OR>1, P<0.05), while ApoA1 was independently negatively associated with the number of coronary artery lesions ( OR=0.140, P=0.007). Conclusions:TyG index is positively associated with the number of coronary artery lesions in patients with stable coronary artery disease.
ABSTRACT
Objective:To determine whether the blood urea nitrogen to serum albumin (B/A) ratio was a useful prognostic factor of mortality in the patients with acute non-variceal upper gastrointestinal bleeding (ANVUGIB).Methods:Totally 1 120 patients with acute upper gastrointestinal bleeding (VUGIB) admitted to the Emergency Department from January 2019 to December 2021 were prospectively and continuously collected and 449 eligible patients with acute non-varicose upper gastrointestinal tract were finally enrolled. The clinical data, laboratory tests and endoscopic results of the patients were recorded, and the data from the 30-day survival group and the non-survival group were compared and analyzed.Results:Significant differences were observed in age, mean arterial pressure, pulse rate, albumin levels, total protein levels, blood urea nitrogen levels, glucose, Glasgow-Blatchford score (GBS), Rockall, and AIMS65 scores between the survival and non-survival groups (all P <0.05). The B/A ratio in the non-survival group was significantly higher than that in the survival group [(24.9 ± 16.4) vs. (9.0 ± 8.6) mg/g, P<0.001]. Receiver operating characteristic (ROC) curve showed that the best cutoff value of B/A ratio for predicting 30-day death was 32.08 mg/g, with a sensitivity of 0.776 and specificity of 0.823. There was a significant difference in the 30-day Kaplan-Meier survival curve between patients with B/A ratio ≥32.08 mg/g and those with B/A ratio <32.08 mg/g (Log Rank 32.229, P<0.001). Multivariate logistic regression analysis revealed that the B/A ratio (≥32.08 mg/g) was associated with 30-day mortality ( OR=4.87, 95% CI: 1.94-6.85, P<0.001). Area under the ROC curve (AUC) for B/A ratio, GBS, Rockall and AIMS65 scores for predicting 30-day mortality were 0.855 (95% CI: 0.807-0.902), 0.849 (95% CI: 0.796-0.901), 0.657 (95% CI: 0.576-0.737), and 0.828 (95% CI: 0.774-0.883), respectively. Conclusions:The B/A ratio is a simple but potentially useful prognostic factor of mortality in the ANVUGIB patients.
ABSTRACT
Breast cancer susceptibility gene (BRCA) is a tumor suppressor gene. The carriers of BRCA mutation have a significantly higher risk of breast, ovarian, pancreatic, prostate and rectal cancers than the general population. BRCA gene detection can effectively evaluate the risk of relevant malignant tumors. In this article, the recent research progress on the relationship between BRCA gene mutations and related cancers is summarized, and the roles of BRCA gene testing in the prevention and management of relevant malignant tumors are discussed.
ABSTRACT
Objective:To investigate the difference of metabolomics between acute heart failure (AHF) patients and control. To find and validate new metabolic biomarkers.Methods:This was a single-center case-control study which included 89 acute heart failure patients admitted to the emergency department of Henan Provincial People's Hospital from January 2018 to June 2019. Eighty people without heart failure and diastolic dysfunction were enrolled as control group whose age and sex were matched to the study group. The fasting blood samples were collected from femoral arterial. Qualitative and quantitative analyses of plasma metabolites were performed in 2 groups by high performance liquid chromatography tandem mass spectrometry (UHPLC-MS), Orthogonal partial least squares-discriminant analysis (OPLS-DA) model and ROC curve method were applied.Results:Compared with the control group, we found that AHF group had higher likelihood to groups with coronary heart disease (37% vs. 7%, P<0.001), hypertension (58% vs. 28%, P<0.001), diabetes (33% vs. 18%, P=0.033), atrial fibrillation (24% vs. 4%, P<0.001), smoking history (42% vs. 18%, P=0.001), and that AHF group had higher creatinine level [(121.6 ± 78.4) vs. (69.0 ± 21.0), P<0.001], higher urea level [(11.5 ± 7.6) vs. (6.2 ± 2.0), P<0.001], higher heart rate [(92 ± 23) vs. (78 ± 14), P<0.001], hypoproteinemia [(32.4 ± 5 .2) vs. (40.4 ± 2.2), P<0.001], and significantly increased BNP level [(4 200 ± 5 229) vs. (100 ± 68), P<0.001], lower left ventricular ejection fraction[(45 ± 8) vs. (57 ± 6), P<0.001], low serum sodium level ( P<0.001). The metabolites of AHF group were significantly different from those of the control group. The metabolites involved amino acids, fatty acids, lipids, nucleosides and their derivatives. Adenine, N-acetyl-L-glutamic, pseudouridine and Gamma-Glutamylcysteine had certain diagnostic value for AHF comparing to control. The AUC were 0.995, 0.932, 0.920 and 0.900. And the AUC value for BNP diagnosis of AHF is 0.978. Conclusions:There were significant differences in metabolism between AHF group and control group including multiple substances. Adenine, N-acetyl-L-glutamic, pseudouridine and Gamma-Glutamylcysteine has similar diagnostic value compared with BNP for diagnosing AHF.
ABSTRACT
Objective To observe the change of JAK-STAT-SOCS signal molecules after interferons alpha acting on the cancerous oral cells in 3 different degrees,namely NOK,DOK and KB cells,and to provide research foundation for the deep understanding of OSCC (oral squamous cell cancer) tumor ceils immune escape mechanism.Methods NOK,DOK,and KB cells were all cultured respectively,and then the third passage cells in the logarithmic growth phase were inoculated in cell culture plate.Blank control group of each hole was added 2 ml complete medium containing 10 ％ FPS.DMSO control group of each hole was added 2 ml complete medium containing 0.1％ DMSO.And in experimental groups containing 10 U/ml,100 U/ml,and 500 U/ml interferons,complete culture medium were added to each hole containing different concentrations of interferons alpha.CP-690550 (100 μmol/L) was added before interferons alpha was added 1 h.All were detected by RT-PCR test and Western blot test after conventional cultured for 24 h.Results RT-PCR detection showed that JAK1 and JAK2 in NOK cells had a small amount of expression,interferons alpha and CP-690550 cells could not influence the expression of JAK1 and JAK2 of NOK group,and there was no statistically significant difference (P ＞ 0.05).Interferons alpha in 100 and 500 U/ml could stimulate the increase of JAK1 and JAK2 expression in DOK and KB cells,and the differences were statistically significant (P ＜ 0.05).CP-690550 could effectively reduce the JAK1 expression of DOK and KB cells,while had no effect on the expression of JAK2,and the differences were statistically significant (P ＜ 0.05).Western blot showed that STAT1,STAT3 and pSTAT3 (Tyr705) all expressed in the control group,while pSTAT1 (Tyr701) didn't express in the control group.Interferons alpha and CP-690550 cells had no effect on STAT1,STAT3 and pSTAT3 (Tyr705) expression of NOK group,and there was no statistically significant difference (P ＞ 0.05).100 U/ml and 500 U/ml of interferons alpha could stimulate the increases of pSTAT3 (Tyr705) expression of DOK and KB cells,and the differences were statistically significant (P ＜ 0.05).While they had no effect on pSTAT1 (Tyr701) expression.CP-690550 could effectively reduce the pSTAT3 DOK and KB cells (Tyr705) expression,and the differences were statistically significant (P ＜ 0.05).Western blot showed that there were expression of SOCS1 and SOCS3 in control group.Interferons alpha and CP-690550 had no effect on SOCS1 and SOCS3 expression of NOK cell group,and there was no statistically significant difference (P ＞ 0.05).100 U/ml and 500 U/ml of interferons alpha could stimulate the increase of SOCS 1 expression of DOK and KB cells,and differences were statistically significant (P ＜ 0.05).For the expression of SOCS3,no influence.CP-690550 could effectively reduce the expression of SOCS1 of DOK and KB cells,and the differences were statistically significant (P ＜ 0.05).Conclusions Interferons alpha activate DOK JAK1 and KB cells and the expression of JAK2,mainly JAK1 activation.Interferons alpha,by activating DOK JAK1 and KB cells and the expression of JAK2,promote STAT3 phosphorylation in Tyr705 locus.Interferons alpha,by promoting STAT3 phosphorylation,further promote the expression of SOCS1,which plays the role in inhibiting interferons alpha and reducing the apoptosis.
