ABSTRACT
Objective: To study the relationship between serum levels of insulin-like growth factor-1 (IGF-1), cystation-C (Cys-C), interleukin-6 (IL-6) and atherosclerosis in middle and old age patient with newly diagnosed type 2 diabetes mellitus (T2DM). Methods: A total of 206 patients with newly diagnosed T2DM at the age of (67.3±10.4) years were enrolled. Based on color Doppler ultrasound examination, the patients were divided into 2 groups: Control group, the patient without carotid plaque or increased intima thickening, n=105 and Experiment group, patient with carotid plaque or increased intima thickening, n=101. The general information, fasting blood glucose, 2h postprandial blood glucose, glycosylated hemoglobin, LDL-C, HDL-C, TG, TC and IGF-1, Cys-C, IL-6, hs-CRP were recorded and compared between 2 groups, BMI was calculated in all patients. Results: Compared with Control group, Experiment group had increased carotid intima-media thickness (CIMT), elevated serum levels of Cys-C, IL-6, hs-CRP and reduced IGF-1, allP<0.05. Multiple Logistic regression analysis showed that CIMT was negatively related to IGF-1 (r=-0.493,P<0.01), positively related to Cys-C, IL-6 and hs-CRP (r=0.464,r=0.219 andr=0.618, allP<0.01). Conclusion: Serum levels of Cys-C and IL-6 might be the independent risk factors for atherosclerosis occurrence in meddle and old patients with T2DM; combined detection of IGF-1, Cys-C and IL-6 could help clinical diagnosis in relevant patients.
ABSTRACT
Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.
ABSTRACT
Objective: To survey and analyze risk factors for coronary artery stenosis in young and middle-aged people to provide thinking for prevention and treatment of atherosclerosis. Methods: The risk factors of 167 patients with coronary artery stenosis proved by coronary angiography from Mar 2011 to Jun 2012 were retrospectively analyzed. Results: Logistic multiple regression analysis indicated that risk factors of coronary artery stenosis in turn were hypertension（1.784），hyperlipidemia（1.708），smoking（1.095）, waist-hip ratio（0.877）, family history of diabetes mellitus（0.781）, high homocysteine（0.608）, serum matrix metalloproteinase-9（0.579）,obesity（0.458）, lack of exercise（0.427）, P<0.01 all according to β value,. Conclusion: Early prevention focusing on relative risk factors may play a vital role for prevention and treatment of atherosclerosis in young and middle-aged people.
ABSTRACT
Objective To reveal the effect of fasting insuline(FINS) and insuline resistance(IR) in the process of benign prostatic hyperplasia(BPH). Methods One hundred and seventeen outpatients( ≥60 ys)with BPH from geriatric department were enrolled into the study. The patients were divided into groups according to their FINS and insulin resistance index (HOMA-IR). The indices of BPH, including volume of prostate ( PV ),prostate specific antigen( PSA ), international prostate symptom score (IPSS), course of BPH were analyzed in both groups. Results The PV ( [ 56. 46 ± 26. 88 ] ml vs [ 44. 84 ± 17.66 ] ml, P = 0. 017 ) and the course ( [ 18. 00 ± 6. 91 ] years vs [ 13.93 ± 7. 74 ] years, P = 0. 031 ) were significantly greater in BPH combined hyperinsulinemias(HINS) group than the BPH with normal FINS group;but we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. The PV( [54. 17 ± 25.38 ] ml vs [42. 26 ±14. 15]ml,P =0. 004)and the course([ 16.58 ±7. 65] years vs [13.49 ±7. 59] years,P = 0. 036) were also significantly greater in BPH combined insuline resistance gruop than the insulin sensitivity group, again we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. Conclusion FINS and IR are risk factors of progressed BPH and can promote the progress of BPH.
ABSTRACT
OBJECTIVE To investigate and analyze the risk factors,clinical characteristics and prevention countermeasures of hospital fungal incfection in old patients with malignant tumors.METHODS To adopt investigation way to review and analyze the clinical data of hospital fungal infection in 165 cases from the old patients with malignant tumors.RESULTS Among 165 cases the infection occurred predominantly in lower respiratory tract(47.2%),and with urological tract being second(19.0%).Of 165 strains of fungi from 165 patients,the first was Candida albicans(55.8%),and the second was C.tropicalis(23.0%).CONCLUSIONS The causes of hospital fungal infection in old patients with malignant tumors are highly associated with the risk factors such as primary tumor,age,radiotherapy,chemotherapy,antibiotics,hormone,invasive operation,and so on.
