Research progress on intrinsic capacity in older adults / 中华老年医学杂志

In order to cope with increasingly severe global population aging, WHO defines "healthy ageing" as the process of developing and maintaining the functional ability required for healthy living of the elderly.Functional ability is related to the interaction between intrinsic capacity(IC)and the environment.IC refers to the sum of all the physical and mental abilities of the individual.Unlike frailty and disability, IC focuses on the functional aspects of the elderly, longitudinally tracking a person's life, rather than on health conditions of the individual at a certain time.Evaluation of IC, including cognitive function, psychological status, sensory function, vitality and locomotor function, is expected to become crucial to predict outcomes and risks of care dependence in the elderly.Starting from screening for IC declines of the elderly in the community, integrated care is formulated taking older people and their caregivers into consideration to improve the quality of life of the elderly to the greatest extent and reduce the social burden.

Effect of alcohol consumption on coronary heart disease in male patients with type 2 diabetes mellitus / 中华健康管理学杂志

Objective:To explore the effect of alcohol consumption on the severity of coronary atherosclerotic heart disease (CHD) in male patients with type 2 diabetes mellitus (T2DM).Methods:A total of 155 male T2DM patients with CHD were enrolled in the study and admitted at the Third Hospital of Hebei Medical University. Clinical and serum biochemical parameters were collected. The effect of alcohol consumption on the severity of CHD was assessed using the Gensini scoring system. Multiple linear regression was performed to analyze the risk factors of CHD in T2DM patients.Results:About 63% of male T2DM patients with CHD were regular (moderate) alcohol consumers and among them, about 60% were classified as excessive drinkers. Compared to patients who did not consume alcohol, the following parameters were all significantly increased (all P<0.05): body mass index [(26.1±3.6) vs (24.9±3.1) kg/m 2]; systolic blood pressure [(142.0±17.6) vs (131.2±17.8) mmHg (1 mmHg=0.133 kPa); diastolic blood pressure (88.6±12.1) vs (83.8±8.9) mmHg)]; total cholesterol [(4.8±1.3) vs (4.3±1.3) mmol/L]; uric acid [(370.9±89.6) vs (349.6±84.3) mmol/L]; smoking rate (76.0% vs 13.3%); and prevalence of hypertension (76.0% vs 13.3%). Compared with patients in the moderate drinking subgroup, the level of low-density lipoprotein cholesterol [LDL-C, (3.2±0.9) vs (2.8±0.9) mmol/L] and plasma fibrinogen [(3.5±0.5) vs (3.9±0.4) mmol/L] were significantly higher ( P<0.05). In addition, the smoking rate and the prevalence of hypertension in the excessive drinking subgroup were significantly higher than those in the moderate drinking subgroup ( P<0.05). Excessive alcohol consumption was the risk factor ( OR=0.259,95% CI: 0.074-0.904, P<0.05), but not the severity factor ( t=-0.58, P=0.565) for CHD in male patients with T2DM, hemoglobinA 1c ( t=3.11, P=0.019), triglycerides ( t=2.30, P=0.039) and LDL-C ( t=4.24, P<0.001) were the risk factors for the severity of CHD. Conclusions:Excessive alcohol consumption may be a risk factor for CHD in male patients with T2DM, but its effect on the severity of CHD still needs further exploration.

Interpretation of "Decade of Healthy Ageing: Baseline Report" / 中华老年医学杂志

The global population aging problem is increasingly serious.For this reason, WHO proposed the goal of "Healthy Ageing" in 2015, that is to maintain and develop the functional ability of the individuals in order to achieve happiness in old age.At the same time, WHO introduced the relationship between functional ability, intrinsic capacity and the surrounding environment in which older adults live and acquire assistance, providing a new way for solving population aging. "Decade of Healthy Ageing: Baseline Report" was published by WHO in January 2021.It took advantage of existing national studies on ageing in 42 countries to assess the global status of healthy ageing at the start of the decade.And then it outlooks ten years ahead, to 2030, what level we can achieve, and what needs to improve ten years from now.

Effect of vitamin D intervention on the outcome of glucose metabolism in patients with impaired glucose regulation / 中华临床营养杂志

Objective To explore the intervention effect of low-dose vitamin D on glucose metabolism of patients with impaired glucose regulation. Methods A total of196 subjects receiving oral glucose tolerance test were enrolled in this study, including individuals with normal glucose tolerance ( NGT group, n=67) and indi-viduals with impaired glucose regulation (IGR group, n=129). The IGR group was divided into intervention group ( n=64) and non-intervention group ( n=65) according to vitamin D intervention ( for 1 year) performed or not. Clinical data and biochemical parameters were collected. Results The level of serum 25(OH)D3 was significantly lower in the IGR group than that of normal control group ( P<0. 05) . After 1 year of low-dose vita-min D intervention, insulin sensitivity increased and insulin resistance decreased in the intervention group as compared with non-intervention group. Diabetes developed less frequently in the intervention group ( 25 of 64 [ 39. 1％] ) compared with non-intervention group ( 30 of 65 [ 46. 2％] ) . But there was no significant differ-ent in diabetes prevalence between the two groups. Conclusions Vitamin D intervention can improve insulin sensitivity and reduce insulin resistance in patients with impaired glucose regulation. Low dose vitamin D can improve the abnormal glucose metabolism outcome in patients with impaired glucose regulation.

Vitamin D and diabetes mellitus / 中华临床营养杂志

Vitamin D deficiency has shown a close relationship with diabetes mellitus.The adequate supplementation of vitamin D can reduce the incidence of diabetes mellitus and improve glucose control by inhibiting inflammatory and immune response,reducing insulin resistance,and promoting insulin synthesis and secretion.

The relationship between serum Leptin concentration and insulin resistance in type 2 diabetes / 中国实用内科杂志

Objective To investigate the relationship between serum Leptin levels and insulin resistance.Methods During 2001-10~2002-08 fasting serum Leptin concentrations were measured with RIA in 196 cases(including 118 type 2 diabetes,78 controls),and height,body weight were measured to calculate body mass index(BMI).Results HbA_1c,SBP,TG,Leptin were correlated with ISI,Leptin concentration were higher in type 2 diabetes than in controls;Leptin concentration was significantly increased in obese subjects,whereas in type 2 diabetes serum Leptin concentration had no significant difference between obese subjects and non-obese subjects.Conclusion Most of obeses subjects have insulin resistance,whether obesity or not,the patients type 2 diabetes have some kind of insulin resistance.

Insulin resistance and abnormal glucose metabolism in patients with primary aldosteronism / 中华内分泌代谢杂志

Objective To analysis the relationship of primary aldosteronism to insulin resistance and abnormal glucose metabolism in patients with primary aldosteronism.Methods One hundred and three patients were diagnosed as aldosterone-producing adenoma(APA),75 cases as idiopathic hyperaldosterenism(IHA),56 patients as metabolic syndrome(MS)in Peking Union Medical College Hospital from September 2003 to December 2005.All patients were accepted 3 h oral glucose tolerance test and calculated HOMA-insulin resistance index (HOMA-IR)by Homeostasis Model.Results The Insulin area under curve[INS_(AUC) 270.8(192.7,370.4)mU?L~(-1)?h~(-1)]、HOMA-IR[3.2(2.4,4.7)]and prevalence of insulin resistance(64.3%)were significantly higher in patients with MS as compared with APA[113.2(81.5,193.6)mU?L~(-1)?h~(-1),1.4(1.0,2.2),16.5%]and IHA[186.9(116.6,243.3)mU?L~(-1)?h~(-1),2.0(1.4,3.1),32.0%]groups (all P＜0.01);The INS_(AUC), HOMA-IR and prevalence of insulin resistance were significantly higher in patients with IHA than those with APA (P＜0.05 or P＜0.01).There was no difference between the prevalence of impaired glucose regulation(41.7%, 34.7%),diabetes mellitus(15.5%,16.0%)in patients with APA,IHA and those with MS(41.1%, 26.8%).Conclusion Insulin resistance is present in primary aldosteronism patients,and the prevalence of insulin resistance is higher in patients with IHA.
