Objective To explore the association between estimated glomerular filtration rate (eGFR) based on creatinine and cystatin C and the SYNTAX score in old patients with coronary heart disease. Methods Two hundred and fifty-six consecutive old patients with coronary heart disease were included in this study. The patients were angiographically diagnosed with coronary heart disease between January 2013 and April 2014 at the Department of Cardiology.eGFR was caculated by using BIS2 equation based on creatinine and cystatin C.SYNTAX score was caculated by SYNTAX score algorithm. Multiple linear regression and ordinal logsitic regreesion was used to analyze the association between eGFR and SYNTAX score. Results In patients with normal of renal function [eGFR≥90 ml/(min·1.73 m2), 110 patients], mild renal insufficiency [60 ml/(min · 1.73 m2) ≤ eGFR<90 ml/(min · 1.73 m2), 98 patients], midrange and severe renal insufficiency[eGFR<60 ml/(min · 1.73 m2), 48 patients], with the decrease in renal function of patients, SYNTAX score increased: (15.42 ± 9.65), (25.24 ± 8.34), (33.73 ± 10.15) scores, P<0.01. eGFR was an independent predictor of SYNTAX score (r=-0.059, P<0.01).eGFR was negatively correlated with SYNTAX score (r=-0.457, P<0.01). Conclusions eGFR is an independent predictor of SYNTAX score and negatively correlated with SYNTAX score in old patients with coronary heart disease. This might be helpful to explain the increased risk of coronary heart disease events and mortality in old patients with renal dysfunction.

BACKGROUND:Matrix extracel ular phosphoglycoprotein phosphorylated extracel ular matrix glycoprotein (MEPE) gene plays an important role in bone mineralization and absorption as wel as the balance of osteoblasts and osteoclasts. Studies on the function and regulatory mechanism of MEPE can provide new ideas for the treatment of osteoporosis. OBJECTIVE:To analyze the regulatory effects of transcription factor Runx2 on MEPE promoter in mouse preosteoblasts, thereby preliminarily studying the Runx2 effects in the process of bone formation and development. METHODS:First of al , the Runx2 eukaryotic expression vector was built according to the gene sequence of Runx2 in Genebank;then the dual luciferase reporter assay was employed to analyze the effects of Runx2 on transcription activity of MEPE promoters with different lengths in order to determine the promoter region in which Runx2 has significant effect. Afterwards, the effects of Runx2 on transcipition activity of MEPE gene promoter which induced by three MAPK signaling pathway inhibitors were investigated. Final y, real-time PCR was used to analyze the expression activity of MEPE gene promoter regulated by Runx2. RESULTS AND CONCLUSION:We successful y constructed the Runx2 eukaryotic expression vector. Dual luciferase reporter assay showed that Runx2 could increase the transcription activity of MEPE gene promoter in preosteoblasts, and the fragment area in which Runx2 exhibited the more significant up-regulatory effectiveness was (-300 to+66)366 bp. Runx2 could increase the transcription activity of MEPE gene promoter by activating the MAPK single pathway. The real-time PCR verified that Runx2 increased the expression activity of MEPE gene promoter. These findings indicate that Runx2 can regulate the express of MEPE gene promoter by the MAPK single pathway, in order to build the basis for exploring the process of bone formation and development.

Vascular cognitive impairment is the only cognitive impairment disease that can be intervened at present. In recent years, the research on its genetic factors has attracted much attention. Among them, apolipoprotein E (ApoE) and its genotypes are closely associated with lipid metabolism, β-amyloid aggregation and deposition, the changes of brain structure and function, and are closely correlated with the pathogenesis of dementia. This article discusses some possible mechanisms of ApoE and its genotypes affecting cognitive function, in order to provide reference for the management of cognitive function in patients with vascular cognitive impairment.

Atrial fibrillation is one of the most common arrhythmia types. With the increase of age, atrial fibrillation will increase the incidence of silent cerebral infarction (SCI), and the correlation between them will lead to the aggravation of cognitive impairment. Atrial fibrillation can be regarded as an independent risk factor for accelerating cognitive impairment in patients with SCI, but the possible mechanism is not completely clear. Therefore, patients with atrial fibrillation should undergo MRI examination, find SCI in time and develop corresponding intervention measures in order to reduce or delay a series of subsequent negative effects. This article reviews the related cognitive impairment of SCI patients with atrial fibrillation.

Objective:To observe the therapeutic effect of intraocular lens (IOL) protected phacoemulsification (PHACO) in patients with hard nucleus cataract.Methods:A randomized controlled clinical study was conducted.A total of consecutive 120 patients (120 eyes) with hard nucleus cataract of Emery grade Ⅳ or Ⅴ were enrolled from January 2019 to May 2022.The patients were randomly divided into PHACO group receiving routine PHACO, IOL protected PHACO group receiving PHACO under IOL protection, and extracapsular cataract extraction (ECCE) group receiving ECCE, with 40 cases (40 eyes) in each group.Finally, 99 patients completed the follow-up, including 30 cases (30 eyes) in PHACO group, 35 cases (35 eyes) in IOL protected PHACO group, and 34 cases (34 eyes) in ECCE group.The total operation time, intraoperative PHACO time and cumulative energy release of each patient were recorded.The corneal endothelial cell density (ECD), coefficient of variation in endothelial cell area (CV), hexagonal endothelial cell ratio (6A), corneal astigmatism and the number of eyes with different grades of uncorrected visual acuity were measured and compared after 3-month follow-up.The intraoperative and postoperative complications were recorded.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Yanbian University Hospital (NO.2023002).Patients were informed of study content and purpose and signed a consent form before treatment.Results:There was no significant difference in ultrasonic energy and time between PHACO group and IOL protected PHACO group ( P=0.691, 0.982).The total operation time was (38.81±2.73) and (36.45±3.45) minutes in PHACO group and IOL protected PHACO group, significantly shorter than (69.60±4.35) minutes in ECCE group (both at P<0.001).There was no significant difference in age, sex, lens nucleus hardness and other baseline data among the three groups before operation (all at P>0.05).Three months after operation, the number of patients with higher uncorrected visual acuity in PHACO group and IOL protected PHACO group was larger than that in ECCE group ( P=0.006, 0.007).The ECD and 6A in IOL protected PHACO group were (2 155.57±177.88)/mm 2 and (41.31±5.18)%, respectively, which were significantly higher than (1 912.64±224.11)/mm 2 and (36.18±3.27)% in PHACO group, and the CV in IOL protected PHACO group was (50.34±5.90)%, which was lower than (55.67±3.30)% in PHACO group, showing statistically significant differences ( P=0.007, 0.003, 0.005).At 1 week and 3 months after the operation, the corneal astigmatism was significantly lower in IOL-protected PHACO group than in ECCE group, but higher than in PHACO group, and the difference were statistically significant (all at P<0.05). Conclusions:Compared with conventional PHACO, IOL-protected PHACO can effectively reduce the damage of corneal endothelium caused by ultrasonic energy, shorten the operation time and reduce postoperative inflammatory reaction compared with ECCE, and does not significantly increase postoperative corneal astigmatism.IOL-protected PHACO is an effective improved surgical method for patients with hard nucleus cataract.
