12 m/s group,n=70;cfPWV≤12 m/s group,n=49). Carotid atheromatous plaque was assessed by Doppler echocardiograph;blood pressure and hemoglobin A1c were measured. Results After adjustment for body mass index (BMI),sex,stroke and fasting blood glucose,logistic multivariable analysis showed that cfPWV associated with age,systolic blood pressure(SBP),pulse pressure,coronary artery disease,diabetes,carotid atheromatous plaque and hemoglobin A1c. Conclusion Arterial stiffness in elderly patients with essential hypertension was strongly positively associated with age,SBP,pulse pressure,coronary artery disease,diabetes,carotid atheromatous plaque and hemoglobin A1c.

Objective To investigate the relationship of BPH in patients with newly diagnosed type 2 diabetes mellitus with age,weight,blood glucose levels.Methods Totally 141 cases with type 2 diabetes and BPH in elderly patients were discussed.Glucose level,the international prostate symptom score (IPSS),prostate volume (PV) and maximum urinary flow rate (Qmax) were determined.Results The levels of IPSS(10.9±2.5 vs.16.4±3.0,P＜0.01; 10.9±2.5 vs.19.4±3.3,P＜0.05) and PV(43.3±7.7 vs.47.9±10.5,43.3±7.7 vs.48.1±8.6,both P＜0.05) were increased in age group of 70-79 years and age group ≥ 80,Qmax in age≥ 80 years was decreased (12.0±2.6 vs.8.5±1.4,P＜0.05) compared with age group of 60-69 years.In contrast to BMI ≤ 24 kg/m2 group,IPSS score,PV and HOMA-IR were increased in BMI ≥ 28 kg/m2 (9.8±3.4 vs.18.8±4.1,P＜0.01; 41.1±10.8 vs.49.1±11.4,1.87±1.1 vs.3.89±2.0,P＜ 0.05).IPSS and PV were higher (12.6±5.7 vs.16.9±4.2,42.9±9.7 vs.48.3±10.6,P＜0.05),Qmax was lower (11.7±1.9 vs.9.0±1.6,P＜0.05) in patients with HbA1c ≥7％ versus HbA1c＜7％.Conclusions Age,obesity,high blood glucose and insulin resistance can promote the progress of BPH in the elderly newly diagnosed type 2 diabetic patients.Therefore,control of weight,and lowering the glycosylated hemoglobin may inhibit the progress of BPH.

Objective To explore the relationship between cognitive impairment and arterial stiffness in elderly patients. Methods A total of 142 elderly patients were enrolled. Cognitive function was assessed by mini-mental state examination (MMSE) and arterial stiffness was assessed by pulse wave velocity (PWV). A full score on the MMSE was 30, and cognitive impairment was defined as a score less than 24. All subjects underwent the measurement of PWV and MMSE . The subjects were divided into 2 groups: 93 were assigned to the normal cognitive function group (MMSE score 24), and the remainders (n=49) were assigned to the cognitive impairment group (MMSE score 24). Results The PWV was significantly increased in the cognitive impairment group than in the normal cognitive function group [(13.3±2.4) m/s vs. (11.8±2.2) m/s, t=3. 775, P=0. 000]. Logistic regression analysis showed that the PWV was also independently and significantly associated with the MMSE score. Conclusions The increase of arterial stiffness is an important risk factor for impaired cognitive function in elderly patients.

Objective To explore the correlation between lower urinary tract symptoms (LUTS) with prostate volume and peak flow rate in aging staff men with benign prostatic hyperplasia (BPH). Methods A total of 180 elderly patients were randomly enrolled. They were diagnosed with BPH by rectal touch and transected ultrasound from April 2008 to December 2008. The international prostate symptom score (IPSS), prostate volume (PV) as well as peak flow rate (QMAX)were analyzed respectively. Results IPSS were ( 9. 1 ± 0. 7 ) scores, ( 12. 1 ± 0. 7 ) scores and (14.0±1.3) scores in 60-69 years old group, 70-79 years old group and more than 80 years old group. PV were (40. 6±1.9) ml, (42. 4±1.9) ml and (48. 7±2.8) ml in corresponding groups, and PV was elevated along with aging (F= 5. 705, 2. 983, P＜0. 05). QMAX were ( 14.7 ± 0. 6) ml/s,(14.0±0. 5) ml/s and (12.6±0.9) ml/s, and QMAX was decreased along with aging (F=2. 131, P＞0. 05). Along with aggravation of LUTS, PV (ml) increased (39. 2±18. 1 vs. 45.7±16.9 vs. 47. 9± 16. 5) and QMAX (ml/s) decreased ( 15.0 ± 4.8 vs. 13. 5 ± 5.06 vs. 11.5 ± 4. 7, F= 3. 427, 4. 742, P ＜0.05). Conclusions The LUTS of patients with BPH is aggravated with aging, at the same time, the degree of LUTS increases with PV and decreases with QMAX. If get active treatment of drugs if available, they may improve their quality of life.
