Chinese Journal of Geriatrics 2012;31(6):491-494
Objective To investigate the blood glucose control level,the characteristics of complications and treatment programme in senile patients with type 2 diabetes.Methods From Aug 2010 to Jul 2011,gender,age,height,weight,disease course and underlying disease were recorded in 119 patients with type 2 diabetes aged 80 years and over.The levels of glycosylated hemoglobin (HbA1c),fasting C-peptide (FC-P) and 2 hours postprandial C-peptide (2h C-P),urinary albumin excretion rate (UAER) were tested.Ultrasonic Doppler examination of lower-limb arteries as well as non-mydriatic colour eye-ground photography were also examined,peripheral nerve lesions were evaluatcd according to the criteria of diabetic neuropathy system (DNS).The patients were divided into two groups:HbA1c<7.0% group (65 cases) and HbA1c ≥ 7.0 % group(54 cases).Results The disease course[(12.1±8.5)years vs.(16.6±7.5)yeas,t=3.01,P=0.003],UAER[(20.2±11.9)μg/min vs.(47.0±21.4)μg/min,t=2.48,P=0.015] and incidence of diabetic nephropathy [23.1%(15/65)vs.50.0%(27/54),x2=9.36,P=0.002] were all less in HbA1c<7.0% group than in HbA1c ≥ 7.0% group,while the levels of FC-P and 2hC P were higher in HbA1c<7.0%than in HbA1c ≥ 7.0% group[(2.1±1.2)μg/L vs.(1.5±1.0)μg/L,t=1.87,P=0.042; (6.5± 3.3)μg/L vs.(4.3 ± 2.9) μg /L,t =2.10,P =0.037].The proportion of patients who took oral hypoglycemic agents was increased while those who received insulin therapy decreased in HbA1c<7.0% group (all P=0.000).The α-glucosidase inhibitors were the most commonly used in each group,followed by metformin and insulin secretagogue,and the thiazolidinediones were rarely used,while there was no significant difference in the proportion of medicine between the groups.The overall incidence of symptomatic hypoglycemia was 23.5%(28/119).It was higher in HbA1c ≥ 7% group than in HbA1c<7.0% group[33.3%(18/54)vs.15.4%(10/65),x2 =5.20,P=0.022].However,71.4%(5/7)of the patients with hypoglycemic coma came from HbA1c<7.0% group.Conclusions There are obvious individual differences in blood glucose control and complications among senile type 2 diabetes patients,thus the characteristics of the elderly should be considered in the choice of drugs while hypoglycemic events should be paid more attention.

Chinese Journal of Geriatrics 2011;30(1):38-41
Objective To investigate the effect of seasonal variation of blood pressure (BP) on the incidence of cardiovascular and cerebrovascular events in the elderly aged 80 years and over.Methods The 67 patients (aged 80-86 years) with essential hypertension were enrolled, the BP were measured at home, in consulting room, and by 24-h ambulatory BP monitor in every season for 2 years. The incidences of cardiovascular and cerebrovascular events were recorded in the meantime.Results Both systolic BP (SBP) and diastolic BP (DBP) were lower in summer than in any other season (P<0. 01 ). SBP was higher in winter than in any other season. (P<0.01), DBP was higher in winter than in summer(P<0. 01). There were no significant differences in SBP and DBP between spring and autumn. The incidence of cardiovascular and cerebrovascular events were higher in winter and summer than in spring and autumn (P<0.05). The season (OR= 1. 525, P=0. 001), BMI (OR =1.145, P=0.018) and heart function (OR= 2. 037, P=0.01) were related to the incidence of cardiovascular events. And the season (OR = 1. 604, P= 0. 001 ), history of cerebrovascular disease (OR= 1. 598, P=0. 034), office-measured SBP (OR=0.960, P=0.013) and ambulatory DBP (OR =0. 936, P = 0. 008) were related to the incidence of cerebrovascular events.Conclusions The blood pressure measured by three methods in the elderly aged 80 and over shows that both SBP and DBP are at the lowest in summer; SBP is at the highest in winter, DBP is higher in winter than in summer. There are no significant differences in BP between spring and autumn. The incidences of cardiovascular and cerebrovascular events are significantly higher in winter and summer than in spring and autumn.

Alliinase is immobilized on pre-activated chitosan microspheres by glutaraldehyde.The optimum immobilization conditions are as follows: glutaraldehyde concentration is 4%,alliinase concentration 20.2U,immobilization time 2h.For immobilized alliinase,the highest activity was allowed at pH 7.0 and temperature 35℃,and the Michaelis constant(Km)was disclosed to be 7.9mmol/L by Lineweaver-Burk plot,and after 10 times reuses the immobilized alliinase lost no more than 10% activity.

Objective To evaluate the influence of the alendronate treatment in early-stage adult nontraumatic avascular necrosis of femoral head. Methods The 83 patients with nontraumatic avascular necrosis of femoral head were enrolled in this study. They were given oral alendronate 70 mg weekly, and evaluated with Harris criteria before and after treatment. Results In the patients with ARCO Ⅰ necrosis, the scores of pain and function were higher after treatment than before [(41.45±3.55) scores vs. (38. 48± 5.55) scores, t = 3. 70, P = 0. 001; (45.06 ± 1.50) scores vs. (43.97 ±2.31) scores, t= 3.76, P= 0. 001]. In the patients with ARCO Ⅱ necrosis, the scores of pain,function and activity were also higher after treatment than before [(40. 40±4.31 ) scores vs. (37.32±6. 65) scores, t=4.06, P=0.00; (42.90±2.70) scores vs. (41.66±3.35) scores, t=3.15, P=0.003; (4.76±0.47) scores vs. (4.42±0.70) scores, t=3.35, P=0.002]. Conclusions Alendronate is effective in treatment of early-stage adult nontraumatic avascular necrosis of femoral head, in particular for ARCO Ⅱ patients. But its long-term effect is worth researching in future.

Objective To investigate the prevalence of osteoporosis,osteopenia,fall and brittle fracture and their associated factors in men aged 80 years and over.Methods In a prospective study,184 study subjects with good self-care ability aged 80 years and over were enrolled.The questionnaire included living habits,falls,comorbidities,related symptoms and medicines.The bone mineral density,hand-grip strength,gait speed,timed up and go test(TUG),chair rising test(CRT),bone turnover markers and related hormones were measured.Binary Logistic regression model was used to analyze associated factors for osteoporosis,osteopenia,fall and brittle fracture.Results The prevalence of osteoporosis (OP)and osteopenia(OPA) were 12.5 % (23/184) and 45.1% (83/184) respectively in this study.The height,weight and body mass index were lower,and serum levels of procollagen type 1 N terminal propeptide(P1NP)and C-telopeptides of type 1 collagen(s-CTx)were higher in osteoporosis group than in normal bone mass(NBM) group(P<0.05,P<0.01).The estradiol levels were lower in OP and OPA group than in NBM group(P< 0.05).The risk factors for OP and OPA included smoking(OR =3.607,P<0.05),decreased body weight (OR=0.823,P < 0.05) and elevated S-CTx level (OR =12.427,P < 0.01).55.4% (102/184) of study subjects had fall history after 80-year old.The prevalence of fragile fracture was 17.4% (4/23),18.1 % (15/ 83)and 3.8%(3/78)in OP,OPA and NBM groups respectively,with total prevalence of 12.0% (22/184).The risk factors for fragile fracture were a decreased total hip BMD(OR 0.017,P<0.05)and fall history after 80-year-old(OR 13.126,P < 0.05).Conclusions Based on associated factors of osteoporosis,osteopenia,falls and fragile fracture in male aged 80 years and over,the primary and secondary prevention of osteoporosis may need a comprehensive geriatric intervention including lifestyle adjustment,fall prevention and pharmacologic treatments.
