Microalbuminuria is the cardinal symptom of diabetes kidney disease (DKD) and is linked to renal function decline. The cardiovascular risk of patients with DKD is much higher than that of the general population, and cardiovascular diseases is the main cause of death in patients with DKD.
We plan to enroll 72 volunteer patients with microalbuminuria. After 1 week waiting period (as the waiting list group), the patients will be randomized to on-venous laser irradiation of blood and low dose OLIB group. Each group will include 36 patients and given intervention three times a week. The intervention will then be crossed over to the other one after 1 week of wash-our period. Outcome measurement includes questionnaires, biochemistry analysis, urine routine analysis.
