Abstract: Aims/Introduction: Patients with diabetes frequently develop orthostatic hypotension (OH). The present study was designed to examine the relationship of blood pressure (BP) circadian rhythms and outcomes in diabetes with OH. Materials and Methods: In the present study, 173 inpatients with type 2 diabetes were enrolled. Patients were divided into an OH group and a non‐OH group according to the BP changes detected in the supine and standing position. Then, 24‐h ambulatory BP was monitored. Patients were followed up for an average of 45 ± 10 months post‐discharge. Outcomes – death and major adverse cardiac and cerebrovascular events, including heart failure, myocardial infarction and stroke – were recorded. Results: There were 61 patients (35.26%) in the OH group and 112 patients (64.74%) in the non‐OH group. In the OH group, the night‐time systolic BP and night‐time diastolic BP were higher, the blood BP rhythms were predominantly of the riser type (67.21%). OH was as an independent marker of riser type circadian rhythm (adjusted odds ratio 4.532, 95% confidence interval 2.579–7.966). In the OH group, the incidence rates of mortality, and major adverse cardiac and cerebrovascular events were increased significantly compared with those in the non‐OH group (11.48 vs 2.68%, P = 0.014; 37.70 vs 8.93%, P < 0.01). Conclusions: In patients who had type 2 diabetes diagnosed with OH, the BP circadian rhythm usually showed riser patterns, and they had increased rates of mortality, and major adverse cardiac and cerebrovascular events.

Chronic renal insufficiency and osteoporosis have become very common among old people in China. Hyperparathyroidism caused by renal insufficiency would result in turbulence of bone metabolism and unbalance between serum calcium and phosphorus. The aim of this study is to investigate the BMD, PTH, CT and 25(OH)-Vit's significance for screening and diagnosing chronic renal insufficiency. In this study, seventy cases with chronic renal insufficiency from Jun. 2010 to Oct. 2013 were selected as the observation group. Meanwhile, another 70 volunteers with normal renal functions were set as the control group. The level of BMD, PTH, CT and 25(OH)-Vit were detected by using ELISA assay. DPX bone density meters (UNIGAMMA X-RAY PLUS) were used for the detection of BMD. The results indicated that BMD levels of the proximal femur (include Troch, Shaft, Total, Neck, Ward) and lumbar vertebra in the observation group were significantly lower while the PTH and CT were significantly higher compared with the control group (P<0.05). A positive correlation was identified between the serum creatinine (Scr) concentrations and CT, PTH, while the correlation with 25(OH)-Vit was considered to be negative. In conclusion, the BMD, PTH, CT, and 25 (OH)-Vit would provide reference in diagnosing and treatment for chronic renal insufficiency. These indexes would be important clinical significance for screening and early diagnose of osteoporosis in these patients.
