Objective:To observe the effect of Xueniaoan tablets on the expression of complement regulatory protein CR1 in IgA nephropathy rats. Methods:Totally 36 SD rats were randomized into the normal group,the model group and Xueniaoan group after 4-day adaptive feeding. Complex method was used to establish IgA nephropathy model,and Xueniaoan group was given Xueniaoan at the dose of 7.0 g·kg-1during the 10thweek and the 12thweek,while the normal group and the model group were fed with normal saline, and the administration course was 3 weeks. The 24-h urine protein was detected,CR1 in red blood cells was detected by ELISA,the renal pathological changes were observed under a light microscope after HE staining,and the expression of CR1 was detected by immu-nohistochemistry. Results:Compared with that in the model group,the 24-h proteinuria in Xueniaoan group was significantly reduced, the number of red blood cell CR1 increased significantly (P<0.05), CR1 in renal tissue increased and the renal tissue injury was light. Conclusion:Xueniaoan tablets can delay the renal damages in IgA nephropathy rats through promoting the expression of CR1.

Objective To predict the prognosis of patients after cardiac surgery by implementing hemodynamic monitoring collective strategy—CHOLKIT protocol,and to explore the practical application value of CHOLKIT protocol,such as early intervention to improve tissue circulation and microcirculation,and predict the timing of extubation.Methods A prospective cohort study was used to analyse 88 patients who underwent cardiac surgery in the First Affiliated Hospital of Xinjiang Medical University from April to October 2020,and they were divided into the survival group (84 cases) and the death group (4 cases) with patient survival or death as the study endpoint.The CHOLKIT protocol was applied to score the central venous pressure (CVP),heart rate (HR),central venous oxygen saturation (ScvO2),lactic acid (Lac),potassium (K+),perfusion index (PI),and toe temperature (T) of patients at different time periods.The correlation between CHOLKIT score and prognosis was predicted based on the scores.Results Some monitoring indexes in the CHOLKIT protocol were related to the mortality,renal injury and duration of mechanical ventilation after cardiac surgery.Conclusion The CHOLKIT protocol can predict the timing of extubation and the change of the condition of patients after cardiac surgery,and early intervention can improve the prognosis of patients,duration of mechanical ventilation and number of days of stay in the intensive care unit.
