ABSTRACT
Objective:To investigate the association between skin advanced glycation end products (AGEs) and carotid atherosclerosis (AS) in subjects with normal glucose regulation (NGR).Methods:This was a cross-sectional study. Data from the Health Management Center of the First Affiliated Hospital of University of Science and Technology between January 2019 to June 2019 were collected. A total of 902 NGR subjects aged 40-79 were enrolled and categorized into control group (530 cases), carotid intima-media thickness (IMT) thickening group (150 cases), and carotid atherosclerosis plaque group (222 cases) based on the carotid ultrasound results. Data as follows were collected, gender, age, blood pressure, body mass index (BMI), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycosylated hemoglobin (HbA 1c) and skin AGEs. Comparison via ANOVA analysis were carried out among the 3 groups. Logistic regression analysis was used to screen the independent influencing factors of carotid atherosclerosis plaque. Spearman correlation analysis was used to evaluate the correlation between AGEs and other parameters, and receiver operating characteristic (ROC) curve was used to evaluate the efficiency of skin AGEs in predicting carotid atherosclerosis plaque in NGR subjects. Results:Among the control group, IMT thickening group and carotid atherosclerosis plaque group, gender, age, systolic blood pressure (SBP), diastolic blood pressure (DBP), TC, LDL-C, FPG, HbA 1c, AGEs were significantly different (all P<0.05). Compared with IMT thickening group, the age, SBP and AGEs of carotid atherosclerotic plaque group were higher [55 (50, 60) vs 53 (49, 56) year; 132 (122, 141) vs 126 (115, 142) mmHg(1 mmHg=0.133 kPa); 74 (67, 81) vs 72 (67, 78) AU] (all P<0.001); compared with the control group, age, LDL-C, HbA 1c and AGEs of IMT thickening group were higher [53 (49, 56) vs 48 (45, 52) year; (2.8±0.7) vs (2.7±0.7) mmol/L; 5.4% (5.2, 5.6)% vs 5.4% (5.1, 5.6)%; 72 (67, 78) vs 70 (66, 76)] (all P<0.05). Age ( OR=1.179, 95% CI: 1.107-1.255), SBP ( OR=1.045, 95% CI: 1.013-1.077), LDL-C ( OR=2.028, 95% CI: 1.036-3.969), AGEs ( OR=1.049, 95% CI: 1.000-1.100) were independent influencing factors of carotid atherosclerotic plaque in population with normal glucose regulated (all P<0.05). AGEs was positively correlated with age, HbA 1c and carotid atherosclerosis plaque ( r=0.407, 0.092, 0.172) (all P<0.01). The area under the ROC curve of skin AGEs for identifying carotid atherosclerotic plaque in NGR population was 0.650 (95% CI 0.601-0.698), the best cutoff value was 70.5, the sensitivity was 65.8%, and the specificity was 56.9%. Conclusion:Skin AGEs level is closely associated with the occurrence of carotid atherosclerosis in NGR subjects.
ABSTRACT
Objective:To investigate the clinical effect of combined treatment of comminuted inferior pole patellar fracture with micro-plate and tension-band wire.Methods:A retrospective cohort study was conducted in 50 patients with comminuted inferior pole patellar fracture (AO classification of type 34-A1) admitted to First Affiliated Hospital of University of Science and Technology of China from October 2018 to October 2020, including 28 males and 22 females, aged 17-77 years［(51.4±11.5)years］. A total of 23 patients were treated with micro-plate combined with tension-band wire (Group A) and 27 patients were treated with cable wire looping combined with tension-band wire (Group B). Fracture union, union time and last follow-up evaluation of knee range of motion and Bostman score were compared between the two groups. Complications (infection, internal fixation failure, internal fixation irritation, etc.) were also observed.Results:All patients were followed up for 12-18 months［(14.1±2.1) months］. All patients had bone union, with no statistical difference between Group A［(9.9±1.8)weeks］and Group B［(10.3±1.4)weeks］in union time ( P>0.05). Knee range of motion was (129.2±9.7)° in Group A at the last follow-up, better than (122.3±11.0)° in Group B ( P<0.05). Knee Bostman score was (27.6±1.8)points in Group A, showing no statistical difference from that in Group B［(26.8±1.9)points］( P>0.05). There were no postoperative complications in Group A. Two patients with tension band shedding of Kirschner wire after fracture healing were found in Group B, with no special treatment given due to no obvious discomfort. Conclusions:For comminuted inferior pole patellar fracture, micro-plate combined with tension-band wire is more effective and provides better knee mobility with no complications of implant failure as compared with cable wire looping combined with tension-band wire. Therefore, the technique deserves clinical promotion.
ABSTRACT
Objective To investigate the effects of aging and the decreased glomerular filtration rate on the prevalence of anemia in elder receiving body check from urban area of Hefei, China.Methods A total of 4547 >60 years subjects received healthy examination in Healthy Center of Anhui Provincial Hospital from January 2005 to December 2007 were enrolled in this study.Anemia was defined as hemoglobin < 120 g/L in men or < 110 g/L in women.Results The prevalence of anemia in the subjects was 4.40% (95% CI: 3.83% -5.05% ) and significantly increased with the aging process and the decline of estimated glomerular filtration rate ( eGFR) .With logistic analyses, increasing age, female, decreased eGFR were major risk factors for anemia Conclusions The morbidity of anemia is 4.40% in old population receiving body check from urban area of Hefei, China.Aging and the decline of eGFR are the independent risk factors of anemia.
ABSTRACT
ObjectiveTo investigate the prevalence and associated risk factors of chronic kidney disease (CKD) in adult population receiving body check from urban area of Hefei, Anhni. MethodsA total of 33 451 subjects who were older than 20 years and received healthy examination in Health Center of Anhui Provincial Hospital from January 2005 to December 2007 were enrolled in this study. CKD was defined as proteinuria, and/or hematuria, and/or using the simplified MDRD equation. ResultsThe prevalence of proteinuria was 2.74% (95%CI: 2.57%-2.92%), hematuria 7.67% (95% CI:7.39%-7.96%), and reduced eGFR 0.80%(95% CI:0.71%-0.90%). 9.92% (95% CI:9.60%-10.25%) subjects had at least one indicator of kidney damage. Age, female, diabetes mellitus, hypertension, and hyperuricemia were independently associated with CKD. ConclusionsThe prevalence of chronic kidney disease is 9.92% in adult population receiving body check from urban area of Hefei, Anhui. Independent risk factors associated with CKD are age, female, diabetes mellitus, hypertension, and hyperoricemia.
ABSTRACT
Objective To investigate the relationship between CD4+CD25+ regulatory T(T-Reg)ceils and the higher prevalence of tumor in elderly people. Methods The frequencies of T-Reg in peripheral blood from 64 health adults.52 healthy elderly people and 64 elderly cancer patients were determined by multi-color detection and multi-parameter flow cytometry.and the relationships among the 3 groups were analyzed and the correlation among CD4+CD25high,CD4+CD25+FoxP3+and CD4+CD25+CD127low were studied. Results Be gated on CD4+ lymphocytes,the reference ranges of CD4+CD25high T cells in the groups of health adults.healthy elderly people and elderly cancer patients were(1.390±0.412)%,(1.729±0.247)%and(2.150±O.769)%respectively,while CD4+CD25+FoxP3+ T cells were(1.1 80±0.343)%,(2.477±0.400)%and (4.980±2.177)%respectively,and CD4+CD25+CD127low T cells were(5.213±0.942)%,(6.186±1.196)%and(7.194±1.538)%respectively.There was the same change rule in CD4+CD25high,CD4+CD25+FoxP3+and CD4+CD25+CD127low T cells of the 3 groups.elderly cancer patients was at the highest.then was healthy elderly people,and the last was health adults.The 3 markers were positively correlated among 3 groups(all P＜0.05).There were gender difference in 3 groups of CD4+CD25high,CD4+CD25+FoxP3+ and CD4+CD25+CD127low T cells. Conclusions The percentages of CD4+CD25high are increased with age and its excessive accumulation is possibly correlated with immunosenescence and the tumor development.
