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

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

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.
文摘BACKGROUND Gestational diabetes mellitus(GDM)is a concern due to its rapid increase in incidence in recent years.AIM To investigate the correlation and predictive value of serum pregnancyassociated plasma protein A(PAPP-A),triglyceride(TG),and 25-hydroxyvitamin D[25-(OH)D]with GDM in early pregnancy.METHODS A total of 99 patients in early pregnancy admitted to Peking University International Hospital from November 2015 to September 2017 were included,and underwent a fasting glucose test and oral glucose tolerance test screening at 24-28 wk of pregnancy.Of these cases with GDM,51 were assigned to group A and the remaining 48 cases without GDM were enrolled in group B.Serum PAPP-A,TG and 25-(OH)D in the two groups were compared and their correlation with blood sugar was analyzed.In addition,their diagnostic value in GDM was determined using receiver operating characteristic(ROC)curve analysis.RESULTS Group A had markedly lower serum PAPP-A and 25-(OH)D levels and a significantly higher serum TG level than group B,with statistical significance(P<0.05).Furthermore,Pearson analysis identified that PAPP-A and 25-(OH)D levels were negatively correlated with fasting blood glucose(FBG)levels(r=-0.605,P<0.001),(r=-0.597,P<0.001),while TG and FBG levels were positively correlated(r=0.628,P<0.001).The sensitivity,specificity,area under the curve(AUC)and optimal cut-off value of serum PAPP-A level in the diagnosis of GDM were 72.55%,82.35%,0.861 and 16.340,respectively,while the sensitivity of TG in diagnosing GDM was 86.27%,the specificity was 66.67%,the AUC was 0.813,with an optimal cut-off value of 1.796.The corresponding sensitivity,specificity,AUC and optimal cut-off value of serum 25-(OH)D were 64.71%,70.59%,0.721 and 23.140,respectively.Moreover,multivariate logistic regression analysis revealed that FBG,vascular endothelial growth factor,Flt-1,serum PAPP-A,TG,and 25-(OH)D were related risk factors leading to GDM in patients.CONCLUSION Serum PAPP-A,TG,and 25-(OH)D levels are all correlated with blood glucose changes in GDM,and are independent factors affecting the occurrence of GDM and have certain value in the diagnosis of GDM.
文摘目的探讨分析非酒精性脂肪肝患者血清25-OH维生素D(25-OH Vit D)的水平变化。方法 100例非酒精性脂肪肝患者作为研究对象,按照随机数字法分为试验组及对照组,每组50例。对照组给予饮食及运动治疗,试验组给予骨化三醇治疗,实验结束后,对比分析两组患者的空腹葡萄糖(FPG)、空腹血胰岛素原(FPI)、体质量指数(BMI)、糖化血红蛋白(HbA1c)、胰岛素抵抗指数(HOMA-IR)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)及血清25-OH-Vit D。结果试验组患者的FPG为(7.3±1.8)mmol/L、FPI为(8.4±2.1)pmol/L、BMI为(24.6±2.4)kg/m2、HbA1c为(7.4±6.3)mg/dl,明显优于对照组的(5.2±0.3)mmol/L、(7.1±1.0)pmol/L、(23.8±1.1)kg/m2、(6.2±7.8)mg/dl(P<0.05)。试验组患者的HOMA-IR(5.27±1.18)、HDL-C(1.1±1.0)mmol/L、LDL-C(3.2±0.6)mmol/L、25-OH Vit D(16.2±5.51)nmol/L明显优于对照组的(3.88±0.91)、(1.6±1.3)mmol/L、(2.8±0.7)mmol/L、(18.6±6.02)nmol/L(P<0.05)。结论非酒精性脂肪肝患者严重缺乏25-OH维生素D,且低水平的血清25-OH维生素D与非酒精性脂肪肝密切相关。
