Objective:To discuss the ameliorative effect of total flavonoids from corn silk(TFCS)on kidney injury in the rats with urate nephropathy,and to clarify the possible mechanism.Methods:Sixty male Wistar rats were randomly divided into control group,model group,positive control group[benzbromarone(BZM)group,5 mg·kg-1·d-1],low dose of TFCS group(20 mg·kg-1·d-1),medium dose of TFCS group(40 mg·kg-1·d-1),and high dose of TFCS group(80 mg·kg-1·d-1),and there were 10 rats in each group.Except for control group,the rats in the other groups were administered potassium oxonate(350 mg·kg-1)and adenine(70 mg·kg-1)by gavage for 4 weeks to establish the hyperuricemic nephropthy models.The rats in different doses of TFCS groups were treated with TFCS for 2 weeks.Speckle blood flow imager was used to detect the renal blood perfusion of the rats in various groups and the kidney coefficients of the rats in various groups were caculated;HE staining and Masson staining were used to observe the pathomorphology and fibrosis degrees of kidney tissue of the rats in various groups and enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of uric acid(UA),creatinine(Cr),blood urea nitrogen(BUN),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)in the serum and levels of β2-microglobulin(β2-MG)and microalbumin(ALB)in the urine of the rats in various groups;Western blotting method was used to detect the expression levels of urate transporter 1(URAT1),glucose transporter 9(GLUT9),and ATP-binding cassette transporter G2(ABCG2)proteins in kidney tissue of the rats in various groups.Results:Compared with control group,the renal blood perfusion volume of the rats in model group was significantly decreased(P<0.01).Compared with model group,the renal blood perfusion volumes of the rats in BZM group and low,medium,and high doses of TFCS groups were significantly increased(P<0.05 or P<0.01).Compared with control group,the kidney weight of the rats in model group was increased,with visible white granular spots on the surface,absence of blood color,and kidney volume was increased.Compared with model group,the kidney volumes of the rats in BZM group and medium and high doses of TFCS groups were decreased,with color tending toward that in control group,and the white granular spots on the surface were significantly reduced.Compared with model group,the kidney coefficients of the rats in BZM group and medium and high doses of TFCS groups were decreased(P<0.01).The HE staining results showed there were no abnormalities in kidney tissue structure in control group,while there were a small amount of brown-yellow urate crystal deposition and interstitial connective tissue hyperplasia in model group;compared with model group,the kidney tissue damage and inflammatory infiltration were alleviated to varying degrees in BZM group and different doses of TFCS groups.The Masson staining results revealed no obvious collagen fiber deposition in control group,whereas significant blue collagen fiber deposition in kidney tissue of the rats was found in model group,and the collagen volume fraction(CVF)was increased compared with control group(P<0.01);compared with model group,the CVFs of the rats in BZM group and different doses of TFCS groups were decreased(P<0.01).The ELISA results showed that compared with control group,the levels of UA,Cr,BUN,IL-6,and TNF-α in serum of the rats in model group were increased(P<0.01);compared with model group,the levels of UA,Cr,BUN,IL-6,and TNF-α in serum of the rats in BZM group and medium and high doses of TFCS groups were decreased(P<0.01).Compared with control group,the levels of β2-MG and ALB in urinary in model group were increased(P<0.01);compared with model group,the levels of β2-MG and ALB in urinary of the rats in different doses of TFCS groups were decreased(P<0.05 or P<0.01).The Western blotting results showed that compared with control group,the expression levels of URAT1 and GLUT9 proteins in kidney tissue of the rats in BZM group and model group were increased(P<0.01),while the expression level of ABCG2 protein was decreased(P<0.01).Compared with model group,the expression levels of URAT1 and GLUT9 proteins in kidney tissue of the rats in different doses of TFCS groups were decreased(P<0.05 or P<0.01),and the expression level of ABCG2 protein was increased(P<0.01).Conclusion:TFCS can significantly alleviate the kidney injury in the rats with urate nephropathy model,and its mechanism may be related to the downregulation of expression of URAT1 and GLUT9 proteins and upregulation of ABCG2 protein expression in kidney tissue.

Yi He Rehabilitation,which is based on traditional Chinese rehabilitation treatments and rehabilitation principles from modern medicine,is effective in staging treatment of post-stroke hemiplegia.This paper systematically discusses the origin and annotation of Yi and He from the perspectives of traditional Chinese medicine and modern medicine.The medicinal connection between Yi and the body and its function is related to unobstructed attunement.Based on the connotation of Yi and He,we believe that the pathogenesis of post-stroke hemiplegia is the comprehensive result of abnormal effects of Yi on the organism at the microscopic level and abnormal effects of He on function at the macroscopic level,featured as tense muscle movement and a pathological process of abnormal motion,including the disturbance of yang qi with body dysfunction,the disorder of spirit with sinews and vessels with diversion,and the variation of brain collateral with physical and mental inconsistency.By inducing relaxation and calmness,Yi He rehabilitation takes effect in staging treatment of post-stroke hemiplegia with characteristic mechanisms.First,by calming ascending yang and relaxing the disordered body in periods of relaxation,it can achieve the maintenance function of the kinematic chain peripherally with passive rehabilitation.Second,by calming the disordered spirit and relaxing the inhibited meridian sinews in spasmodic periods,it can reconstruct the neural plasticity of motor function centrally with assistive rehabilitation.Third,by calming damaged brain collateral and relaxing the impassable zang organs in the recovery period,it can close the central-peripheral-central loop of rehabilitation with active rehabilitation.

Objective To compare the quality of life,nutritional status and immune function of gastric cancer patients with digestive tract reconstruction using Roux-en-Y anastomosis and uncut Roux-en-Y anastomosis after radical gastrectomy.Methods 86 patients with gastric cancer were selected from May 2015 to June 2017 with radical total gastrectomy.According to the different ways of the reconstruction of the digestive tract,the patients were divided into URY group (non-severed group,41 patients) and RY group (traditional group,45 patients).The quality of life of the two groups was compared at 1 month,3 months and 6 months after operation.The nutritional status of albumin,prealbumin,transferrin,hemoglobin,retinol binding protein and weight,as well as CD4+ lymphocyte,CD8+ lymphocyte,CD4+/CD8+ ratio,IgG,IgM,IgA and other immune related indexes were observed at pre-operation and 1 month,3 months and 6 months after operation.Results As for quality of life,the score of diet limitation in group URY was significantly lower than that in group RY at 1 month after operation (P<0.05),and no significant difference at 3 months and 6 months after operation (P>0.05);As for anxiety,the score of group URY was higher than that in group RY (P< 0.05) at 1 month after operation (P<0.05),and was lower than that in group RY at 3 months and 6 months after operation (P<0.05).As for dry mouth,group URY was higher than that in group RY (P<0.05) at 3 months and 6 months after operation (P<0.05),and the other indexes were not statistically significant (P> 0.05).As for the nutritional indexes,prealbumin in the URY group was higher than that in the RY group at 6 months after operation (P<0.05),and the rest were not statistically significant (P>0.05).There was no statistical significance in immune indexes between the two groups (P > 0.05).The postoperative hospitalization time of URY group was less than that of RY group (P<0.05),and the incidence of mild reflux symptoms was lower than that of RY group (P<0.05).There was no significant difference in the incidence of other complications between the two groups (P>0.05).Conclusion Except for the length of hospitalization and postoperative complications in which uncut Roux-en-Y anastomosis was superior to Roux-en-Y anastomosis,there is no significant difference in quality of life and nutritional and immune indicators between the two alimentary tract reconstruction methods.
