The physical function of even a person getting on a wheelchair could be tested in all subjects. Blood was collected by venipuncture and the serum 1, 25-hydroxy vitamin D (1, 25OHD) concentration was measured. The Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment-Japanese version (MoCA-J) was used for the cognitive function test. Physical function was measured objectively using the Timed UP and Go (TUG) and 4-m walking test (4MWS). A significant positive correlation was found between serum 1, 25OHD and MMSE or MoCA-J. It is expected that an elderly person can maintain a mean serum 1, 25OHD level of about 100 pg/mL for preventing early cognitive disorder. In the present study, a significant positive correlation was found between urinary 25-hydroxy vitamin D (25OHD)/creatinine and MMSE or MoCA-J. Our results showed that urinary 25OHD might be a useful biomarker for predicting cognitive disorder. There was a significant negative correlation between serum 1, 25OHD and TUG or 4MWS. These findings suggest that serum 1, 25OHD levels might serve as a useful index to improve cognitive and physical functional impairment.展开更多

Methodology: One hundred and sixty seven subjects were recruited for the cross-sectional study at King Fahad Medical City, Saudi Arabia. Blood samples were analyzed for biochemical parameters. Serum 25-hydroxyvitamin D and resistin levels were measured for all the participants. Result: Fifty six type-1, 55 type-2 diabetic patients and 56 healthy controls were recruited. Serum 25-hydroxyvitamin D level in the control group was 44.21 ± 41.80 μg/ml compared to 50.67 ± 35.60 μg/ml in the diabetic group (P = 0.427) with no significant different between type-2 diabetes mellitus and type-1 diabetes mellitus (P = 0.628). Resistin level in the control group was 14.00 ± 7.39μg/ml compared to 20.21 ± 16.94 μg/ml in the diabetic group (P ≤ 0.01), no significant difference between type-2 diabetes mellitus and type-1 diabetes mellitus (P = 0.817). Resistin in those taking vitamin D supplementation was 21.34 ± 18.27 μg/ml;and in those not taking vitamin D supplementation, it was 17.4 ± 11.19 μg/ml;(P = 0.237). There was significant negative correlation between 25-hydroxyvitamin D and resistin in type-2 diabetes mellitus (P ≤ 0.043) and no significant correlation was found between vitamin 25 (OH) D and resistin level in type-1 diabetes mellitus (P = 0.538). Blood urea and creatinine showed significant positive correlation with vitamin 25 (OH) D in one hand and resistin level on the other hand. Discussion and Conclusions: Several in vitro and in vivo studies have confirmed that the vitamin 25 (OH) D have numerous important functions in the body. The circulating vitamin 25 (OH) D and resistin levels were associated with general inflammation in renal diseases. This study showed significant negative correlation between resistin level and vitamin 25 (OH) D in type 2 diabetes mellitus reflecting their roles in glucose homeostasis. The positive correlation of resistin and vitamin D with urea may reflect their involvement in kidney dysfunction. The level of serum resistin showed slight increase in diabetic patients compared to control group and it was higher in type-2 diabetes mellitus. More efforts are needed to explore the physiological mechanism of vitamin 25 (OH) D and resistin action in metabolic disorders.展开更多

Methods: A total of 258 patients with newly diagnosed T2DM in this hospital between July 2015 and July 2017 were selected as T2DM group, and 100 subjects with normal glucose metabolism who received physical examination in this hospital during the same period were selected as normal control group. The differences in serum 25(OH)D3 levels, ultrasonic carotid atherosclerosis parameters as well as serum lipid metabolism index and inflammatory adipocytokines contents were compared between the two groups. Pearson test was used to assess the correlation between serum 25(OH)D3 level and carotid atherosclerosis in patients with newly diagnosed T2DM. Results: Serum 25(OH)D3 content of T2DM group was lower than that of normal control group;PWV and CC levels of the ultrasonic left and right carotid arteries were higher than those of normal control group;serum lipid metabolism indexes TC and LDL-C contents were higher than those of normal control group whereas HDL-C content was lower than that of normal control group;serum inflammatory cytokine APN content was lower than that of normal control group whereas CHEM, RSTN and LEP contents were higher than those of normal control group. Pearson test showed that serum 25(OH)D3 level in T2DM patients was directly correlated with the degree of carotid atherosclerosis. Conclusion: Serum 25(OH)D3 level is abnormally low in patients with newly diagnosed T2DM, and the specific decrease is directly correlated with the degree of carotid atherosclerosis and can be used as an early evaluation indicator for carotid artery disease in patients with T2DM.展开更多

Methods: Retrospective analysis of 250 admitted type 2 diabetes inpatients admitted to the endocrinology department of qinghai provincial hospital of traditional chinese medicine from september 2022 to december 2023, collated and analysed the general data and laboratory indicators of the patient cases, and applied spss26.0 to process and analyse the data and explore the differences in the general conditions and commonly used clinical nutritional indicators of type 2 diabetes in patients with different 25-hydroxyVitamin D levels. The differences between the different 25-hydroxy Vitamin D levels in type 2 diabetes mellitus patients. Results: 1) A total of 250 inpatients with type 2 diabetes mellitus were included in this study, of which 56 cases (22.4%) were patients with 25 hydroxyvitamin D deficiency [25(OH)D P P P P > 0.05). 3) The distribution of some laboratory indexes among the three groups of patients was differentiated, with the average level of glycated haemoglobin in the lack group being significantly higher than that of the remaining two groups, the average level of albumin being significantly lower than that of the remaining two groups, and the average level of haemoglobin being significantly lower than that of the good group (P P > 0.05). Conclusion: The 25(OH)D level of type 2 diabetes mellitus inpatients is not optimistic. In clinical diagnosis and treatment, we should pay attention to the changes in 25 hydroxyvitamin D levels and other nutritional indexes of patients with type 2 diabetes mellitus, and focus on the control of blood glucose levels and timely supplementation of vitamins, proteins, and lipids, in order to improve the patients’ physical status, reduce the incidence of complications, and improve the clinical efficacy and the patients’ quality of life.展开更多
