Objective To evaluate the association between serum cystatin C and carotid atherosclerosis in patients with type 2 diabetes mellitus.Methods A total of 318 patients with type 2 diabetes mellitus were enrolled in this study.According to the results of carotid color Doppler ultrasound in the patients were randomly divided into two groups:CIMT abnormal group (CIMT was equal to or larger than 0.9 mm,with or without associated with carotid artery plaque formation)CIMT and normal group (CIMT <0.9 mm,and it was not associated with carotid artery atherosclerotic plaque formation.Differences in serum cystatin C,serum lipid and lipoprotein,fasting plasma glucose and other biochemical markers between the two groups were analyzed by using Student's t test.The correlated factors of the carotid thickness and plaque appearance were analyzed by Logistic regression analysis.Results The serum cystatin C levels of the CIMT abnormal group were higher than the normal CIMT group[(1.24 ±0.22)mg/L vs.(1.05 ±0.41)mg/L, t =4.949,P <0.001).Multivariate logistic regression analysis showed adjusted for gender,age and other factors,ser-um cystatin C was independently associated factor of CIMT (OR =2.563,95% CI:1.026 ~6.403,P =0.044). Conclusion Our data suggest that serum cystatin C is significantly associated with carotid atherosclerosis.

In the era of information technology, the construction of a harmonious doctor-patient relationship is inseparable from the support of information technology. The use of blockchain technology in the medical and health field plays an important role in promoting the construction of a harmonious doctorpatient relationship in the new era. Discuss the organic integration of blockchain technology and the construction of a harmonious doctor-patient relationship in the new era at the three levels of technology, method, and path, and find that the blockchain can provide both technical support and method support for the construction of a harmonious doctor-patient relationship in the new era; Blockchain technology is conducive to promoting the construction of a harmonious doctor-patient relationship in the new era by developing distributed personal lifelong medical accounts, establishing a shared and interactive medical resource service community, and designing a tracking management model for the medical service process.
