摘要:Diabetic nephropathy( DN) is the most critical microvascular complication in patients with diabetes mellitus. In China,therapeutic options also include application of Chinese herbal compounds guided by syndrome differentiation treatment. Chinese medical treatment can attenuate greatly symptoms and improve the life quality,by contrast,the effects of reducing the objective indicators such as urine protein and serum creatinine are far from satisfactory. This article summarizes the theory of genuine yin and vital essence proposed by ZHANG Jingyue,a renowned TCM doctors in Ming Dynasty,as the following explanations. Firstly,genuine yin staying at the gates of vitality in kidneys,saves essence of five zang-organs. Secondly,genuine yin has both the functions of water and fire,as the carrier of yin essence and the foundation of yang essence. Thirdly,treatment of disease should be based on the root cause which locates in vital essence. Fourthly,the primary treatment of deficiency of yin essence is nourishing genuine yin by application of Radix Rehmanniae Praeparata( Shu Dihuang) to reinforce qi and produce yin essence. After the analysis of clinical trials,we think that the core pathogenesis of DN is deficiency of genuine yin leading to deficiency syndrome transforming to excess syndrome. And the five rules of Chinese medical treatment on DN are listed as: the primary therapeutic principle is nourishing genuine yin;the primary therapy is powerfully tonifying genuine yin through the way of reinforcing qi and producing genuine yin,through the way of controlling and astringing essence to strengthen effects,and through the way of eliminating pathogenic factors and recovering essence to aid to nourishing genuine yin.
摘要:Objective To explore the effects and mechanism of Lishi Huoxue( damp-dispersing and blood-activating) formula and two decomposed recipes Chinese herbal compound,on the vascular endothelial cells by detecting the serum levels of functional indicators of vascular endothelial cells and the aortic morphology of the rat model of hyperuricemia. Methods Male SD rats were randomly divided into seven groups: normal group,model group,benzbromarone group,Simiao Pill group,Lishi Huoxue formula( LSHX) group,decomposed recipe I for clearing heat and damp( recipe I) group,decomposed recipe Ⅱ for activating blood and resolving stasis( recipe Ⅱ) group. The rat model of hyperuricemia was established by intragastrical( i. g.) administration of yeaut and adenine. After successful modeling,rats of each medication group were administered i. g. with corresponding drugs,while normal group and model group were i. g. distilled water for consecutive 14 days. Then the serum contents of uric acid( UA)and nitric oxide( NO) were detected by ultraviolet-visible spectroscopy,and endothelin( ET-1),thromboxane B2( TXB2) and 6-keto-PGF1αwere measured by radioimmunoassay. Besides,thoracoabdominal aorta of all rats were dissected and stained using HE and Masson. Results Compared with normal group,the serum level of UA,ET-1 and TXB2 increased significantly in model group( P < 0. 05) and level of NO and 6-keto-PGF1αdecreased( P < 0. 05). Compared with the model group,the serum contents of UA,ET-1 and TXB2 showed significantly decreasing in LSHX group( P < 0. 05),while in recipe I group UA and ET-1 decreased( P < 0. 05) and serum contents of NO,6-keto-PGF1αin LSHX group,recipe ⅠandⅡ groups increased( P < 0. 05). Furthermore,compared with LSHX group,the levels of TXB2 in both recipe groups and ET-1 in recipe Ⅱ group showed on statistical difference. Although LSHX and the two partial prescriptions( recipe I,II) protected against the injury of aorta,the whole prescription( LSHX)was more effective than the two decomposed recipes. Conclusion LSHX formula could reduce the serum UA,and protect vascular endothelium and the aorta of rats with hyperuricemia.
摘要:Objective To observe the protective effect of Tangshenqing Formula II( TSQF) on the renal function of mice with type 2 diabetes mellitus( DM). Methods KK-Ay mice,a spontaneous DM model,were fed with fat-enriched diet for three weeks. Based on their serum glucose( Glu) and body weight( BW),the mice were divided into model group,valsartan group,high,middle,and low dose of TSQF( high-,mid-,low- dose) group( n = 6 each) and were treated for consecutive 12 weeks.
