ABSTRACT

BACKGROUND AND AIM@#Remnant cholesterol (remnant-C) mediates the progression of major adverse cardiovascular events. It is unclear whether remnant-C, and particularly cumulative exposure to remnant-C, is associated with nonalcoholic fatty liver disease (NAFLD). This study aimed to explore whether remnant-C, not only baseline but cumulative exposure, can be used to independently evaluate the risk of NAFLD.@*METHODS@#This study included 1 cohort totaling 21,958 subjects without NAFLD at baseline who underwent at least 2 repeated health checkups and 1 sub-cohort totaling 2,649 subjects restricted to those individuals with at least 4 examinations and no history of NAFLD until Exam 3. Cumulative remnant-C was calculated as a timeweighted model for each examination multiplied by the time between the 2 examinations divided the whole duration. Cox regression models were performed to estimate the association between baseline and cumulative exposure to remnant-C and incident NAFLD.@*RESULTS@#After multivariable adjustment, compared with the quintile 1 of baseline remnant-C, individuals with higher quintiles demonstrated significantly higher risks for NAFLD (hazard ratio [HR] 1.48, 95%CI 1.31-1.67 for quintile 2; HR 2.07, 95%CI 1.85-2.33 for quintile 3; HR 2.55, 95%CI 2.27-2.88 for quintile 4). Similarly, high cumulative remnant-C quintiles were significantly associated with higher risks for NAFLD (HR 3.43, 95%CI 1.95-6.05 for quintile 2; HR 4.25, 95%CI 2.44-7.40 for quintile 3; HR 6.29, 95%CI 3.59-10.99 for quintile 4), compared with the quintile 1.@*CONCLUSION@#Elevated levels of baseline and cumulative remnant-C were independently associated with incident NAFLD. Monitoring immediate levels and longitudinal trends of remnant-C may need to be emphasized in adults as part of NAFLD prevention strategy.

ABSTRACT

The real-time reported data of treated patients from July 2017 to June 2019 Nanxiang Hospital of Jiading District were collected from chest pain center platform. The results showed that the average time of completing ECG examination from the first medical contact was 1.3 to 6.9 min with a median of 1.9 min (1.7, 2.2), meeting the quality control requirements (10 min); the time required to obtain troponin test results was 13.0 to 48.4 min with a median of 14.1 min (13.4, 18.1), meeting the requirements for quality control of 20 min; time from entry to transfer out of PCI patients was 19.0-100.0 min, with median 37.2 (29.3, 66.6) min, basically reaching quality control (30 min); the entering catheter chamber rate of STEMI patients was 50.0% to 100.0% with a median of 100.0% (73.3%, 100.0%), meeting the requirements of quality control (≥50%). Through the active construction, the main quality control indicators were well reached, the reported cases were basically stable, and the disease distribution was basically reasonable in the primary-level chest pain centers. Informed notification of transshipment and subsequent management of low-risk chest pain patients need to be further strengthened. It is suggested that the construction of chest pain centers should establish long-term normal working mechanism, strengthening the control of key quality control indicators, to play the important role of the regional treatment system.

ABSTRACT

OBJECTIVE: To compare the applicability of two risk assessment methods to assess the occupational health risk of key industries of dichloromethane in Shenzhen City. METHODS: The Singapore ministry of manpower risk(MOM) method and the comprehensive index method were used to evaluate the risk of 123 positions in 47 key industries of dichloromethane in Shenzhen City. Then the risk classification results of the two assessment methods were compared. RESULTS: The results of MOM method showed that the median and the 0 th to 100 th percentile [M(P_0-P_(100))] of risk of dichloromethane in electronics industry was 2(2-3), and the risk level was low to medium. The M(P_0-P_(100)) of risk of dichloromethane in printing industry was 2(2-4), and the risk level was low to high. The results of the comprehensive index method showed that the M(P_0-P_(100)) of risk of dichloromethane in electronics industry and printing industry were 3(3-4), and the risk level was medium to high. There was no significant difference in the assessment results of occupational health risk of dichloromethane between the electronic industry and the printing industry by MOM evaluation method(P>0.05). The occupational health risk assessment of dichloromethane in printing industry was higher than that in electronic industry by the comprehensive index method(P<0.01). Both evaluation methods were not consistent in the electronics industry and the printing industry(k values were-0.01 and 0.04, all P>0.05). After merging the evaluation results of the two industries, there was no consistency in the evaluation results of the two evaluation methods(k value=0.01, P>0.05). CONCLUSION: The risk level of dichloromethane in printing industry is higher than that in printing industry in Shenzhen City. The comprehensive index method may comprehensively and objectively assess the occupational health risk level of dichloromethane in key industries in Shenzhen City.

ABSTRACT

Objective To investigate the effect of stress-induced hyperglycemia (SHG) on myocardial perfusion and clinical prognosis in elderly patients with acute myocardial infarction (AMI) who underwent primary percutaneous coronary intervention (PCI). Methods In this study, 459 elderly patients with first-time occurrence of acute ST-elevation myocardial infarction (STEMI) who underwent primary PCI within 12 h from January 2012 to January 2015 were enrolled and followed up. All patients were divided into three groups according to serum glucose (SG) on admission: normal group (SG11.1 mmol/L, 142 patients). Myocardial perfusion indexes, including ST segment resolution (STR), TIMI myocardial perfusion grade (TMPG), peak value of creatine kinase (CK)-MB, left ventricular ejection (LVEF), and major adverse cardiac events (MACE) of patients in three groups were measured and compared after emergency PCI. Results The blood glucose levels were increased, ST-elevation 2 h after PCI were well declined, the percentages of patients with TMPG 2-3 were decreased and peak values of CK-MB were increased in the three groups (P<0.05). After 12 months of follow-up, Kaplan-Meier survival analysis showed that cumulative non-events survival rates in three groups had significantly different: 89.2% (132/148) vs. 85.8% (145/169) and 76.1% (108/142), P<0.05. Multivariate Cox regression analysis showed that SHG was the independent predictor for the occurrence of MACE in patients undergoing PCI after adjusting for age and gender (P<0.05). Conclusions SHG in elderly patients with STEMI can decrease myocardial perfusion level after primary PCI, which will lead to high incidence of MACE.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the impact of pre-primary percutaneous coronary intervention (PCI) β blocker use on the development of no-reflow in ST-segment elevation myocardial infarction (STEMI) patients post PCI.</p><p><b>METHODS</b>We retrospectively evaluated 1 615 outpatients with STEMI who underwent primary primary PCI with in 12 hours from symptom onset admitted to Beijing Anzhen Hospital and Chinese people's liberation army general hospital from January 2007 to June 2011. The study population was divided into the following 2 groups: β blocker group (pretreatment with β blockers ≥ one month before admission, n = 257) and non-β blockers group (pretreatment with β blockers < one month before admission or had no β blocker, n = 1 358). No-reflow was defined as TIMI grade < 3 in last imaging of coronary artery after stenting. Multivariable logistic regression analyses were used to identify independent predictors for the no-reflow after primary PCI.</p><p><b>RESULTS</b>Incidence of the no-reflow was significantly lower in the β blocker group than in non-β blockers group (13.6% (35/257) vs. 21.2% (289/1 358), P = 0.017). Multivariable logistic regression analysis revealed that pre-PCI β blocker use was a protective predictor of the no-reflow (OR = 0.594, 95%CI:0.394-0.893, P = 0.012), while age ≥ 55 years old (OR = 2.734, 95%CI:1.959-3.817, P < 0.001), high neutrophil count (OR = 1.257, 95%CI: 1.169-1.351, P < 0.001), admission plasma glucose (OR = 1.060, 95%CI:1.018-1.103, P = 0.004), Killip classes IV (OR = 3.383, 95%CI:1.924-5.948, P < 0.001) and reperfusion time ≥ 4 h(OR = 1.503, 95%CI:1.124-2.009, P = 0.006) were risk factors for the development of no-reflow post PCI.</p><p><b>CONCLUSION</b>Previous long term β blockers use before STEMI is associated with lower incidence of no-reflow in patients with STEMI treated with primary PCI.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the DNA methylation changes induced by hydroquinone (HQ) in human bronchial epithelial cells and to explore the role of poly (ADP-ribose) polymerase-l (PARP-l) in this process.</p><p><b>METHODS</b>Human bronchial epithelial 16HBE cells and PARP-l-deficient 16HBE cells (16HBE-shPARP-l cells) were exposed to HQ (10, 20, 40, 60, and 80 µmol/L) for 48h, while control cells were treated with an equal volume of PBS solution. The changes in genomic DNA methylation were investigated by high-performance capillary electrophoresis, and the expression levels of PARP-l and DNA methyltransferase 1 (DNMT1) were measured.</p><p><b>RESULTS</b>The percentages of methylated DNA of overall genome (mCpG%) in 16HBE and 16HBE-shPARP-l cells were 4.89%±0.07% and 9.53%±0.51%, respectively; after treatment with 5-aza-2'-deoxycytidine for 72 h, mCpG% decreased to 3.07±0.12% and 6.34%±0.3%, respectively. The one-way analysis of variance revealed significant differences in mCpG% between the cells exposed to different concentrations of HQ in both 16HBE and 16HBE-shPARP-l groups (F = 61.25, P < 0.01; F = 60.36, P < 0.01). For 16HBE cells treated with HQ (10, 20, 40, 60, and 80 µmol/L), the mRNA expression levels of PARP-1 were 145.0%, 159.0%, 169.0%, 215.0%, and 236.0%, respectively, compared with those in the control group, with significant differences (P < 0.01 for all); for 16HBE-shPARP-l cells treated with HQ (10, 20, 40, 60, and 80 µmol/L), the mRNA expression levels of PARP-l were 170.0%, 223.0%, 264.0%, 327.0%, and 320.0%, respectively, compared with those in the control group, with significant differences (P < 0.01 for all). When the dose of HQ reached 20, 40, 60, and 80 µmol/L, the mRNA expression levels of DNMT1 in 16HBE group were 114.0%, 126.0%, 136.0%, and 162.0%, respectively, compared with those in the control group, with significant differences (P < 0.01 for all); when the dose of HQ reached 10, 20, 40, 60, and 80 µmol/L, the mRNA expression levels of DNMT1 in the 16HBE-shPARP-l group were 141.0%, 165.2%, 186.9%, 202.1%, and 217.3%, respectively, compared with those in the control group, with significant differences (P < 0.01 for all).</p><p><b>CONCLUSION</b>HQ can induce hypomethylation in 16HBE cells, and PARP-1 can regulate DNA methylation in 16HBE cells by influencing the expression and activity of DNMT1.</p>

ABSTRACT

Objective To investigate the expression of p40 (ANp63),p504s and their diagnostic value in benign and malignant lesions of the prostate,also to compare with the expression of p63.Methods The expression of p40 (ANp63),p63 and p504s in 92 cases of benign prostatic hyperplasia and 67 cases of prostatic carcinoma were detected by immunohistochemical MaxVision method.Results p40 and p63 were positive in 95.7 % (88/92) and 87.0 % (80/92) of benign prostatic hyperplasia,and the intermittent and low expression in p63 were more common than those in p40.The positive expression rate of p40 was obviously higher than that of p63 in benign prostatic hyperplasia (x2 =4.381,P < 0.05).Both p40 and p63 showed no expression in prostatic carcinoma,but p63 appeared with abnormal cytoplasmic staining in many cases of cancer cells,which was 17.9 % (12/67).The specificity of combined detection of p40 and p504s in the diagnosis of benign prostatic hyperplasia and prostate carcinoma was as high as 100 %.Conclusion p40 is more sensitive than p63 in prostate basal cells.Combined detection of p40 and p504s is valuable to distinguish poorly differentiated benign prostatic hyperplasia from prostatic carcinoma.

ABSTRACT

Objective To investigate the effect of intracoronary application of tirofiban on coronary slow flow patients with acute myocardial infarction during primary percutaneous coronary intervention (PPC1).Method It was a retrospective analysis of 187 patients with acute myocardial infarction treated with PPCI in the emergency department of Beijing Anzhen Hospital enrolled in this study from January,2008 through January,2011.The patients divided into 2 groups in terms of intra-coronary administration of tirofiban (tirofiban group) and intra-coronary use of nitroglycerol (control group).Data were statistically analyzed by using SPSS 13.0 software.Categorical variables were analyzed using x2 test and continuous variables were compared by t test.Results Between two groups,there were no differences in preoperative systolic pressure (P =0.245),the rate of TIMI flow 3 (P =0.568) after PPCI and ST segment resolution (P =0.824),LVEF (P =0.275) and in-hospital mortality (P =0.502).Compared with tirofiban group,the systolic pressure was lower and the rate of using intra-aortic counter-pulsation was higher in control group.Although the incidence of slight bleeding in the control group was lower than that in the tirofiban group,no severe bleeding was observed in both groups.Conclusions The effect of intracoronary use of tirofiban was similar to that of nitroglycerol in terms of improving slow flow of coronary artery.It could safely and effectively reduce the incidence of the coronary slow flow in the patients after PPCI,but it produced a little impact on systolic pressure.It may be a better method of choice for AMI patient with low blood pressure.
