基于Klotho基因多態(tài)性對(duì)糖尿病腎病中醫(yī)證候的研究
[Abstract]:Diabetic nephropathy (DN) is one of the most serious microvascular complications of diabetes mellitus. It is considered that genetic background plays an important role in the genesis and development of DN. Therefore, it is of great significance to elucidate DN and its risk factors in the diagnosis and clinical treatment of the disease from the genetic perspective. The association between the risk of diabetic nephropathy and the symptoms and syndrome types of diabetic nephropathy patients was studied, and the possible susceptible genotypes were screened for timely targeted prevention and treatment of potential high-risk patients. A total of 178 subjects were collected and analyzed, including 123 cases (56 patients with type 2 diabetes mellitus and 67 patients with type 2 diabetic nephropathy) and 55 healthy controls. The subjects were collected for general information, observed for TCM syndromes, and genomic DNA was extracted by centrifugal column method. Gen Bank of information center obtained Klotho gene information and sequence of promoter region G-395A and exon region F352V, C370S. Single nucleotide polymorphism (SNP) was detected by PCR and direct sequencing. SPSS software was used to analyze the genotype and allele distribution of Klotho SNP in type 2 diabetes mellitus and diabetic nephropathy. To explore the relationship between Klotho SNP and diabetes mellitus and diabetic nephropathy, and to further analyze the relationship between Klotho gene polymorphism and the main symptoms and syndrome types of diabetic nephropathy. Three genotypes of Klotho gene G-395A locus were detected by using Rev Man 5.3 software for meta-analysis. F352V and C370S only detected two genotypes.2, G-395A genotype and allele distribution frequencies were not significantly different between the case group and the healthy control group (X2 = 1.197, P = 0.274; X2 = 1.083 P = 0.298); however, there were significant differences between the type 2 diabetes mellitus group and the diabetic nephropathy group (X2 = 5.016, P = 0.025, OR = 2.475, 95% CI: 1.108-5.528; X2 = 5.083 P = 5.528). 872, P = 0.015, OR = 2.404, 95% CI: 1.166-4.956; G-395A genotype distribution frequency in diabetic nephropathy patients was not associated with Mogensen stage (Z = 0.123, P 0.05); Logistic regression analysis showed that carrying allele A, hypertension history, diabetes duration and glycosylated hemoglobin were statistically associated with DN (OR: 1.774, 2.198, 1.735, 1.306, 95% C, respectively). I was 1.195-2.635, 1.330-3.632, 1.183-2.548, 1.022-1.671). 3. The genotype and allele frequencies of G-395A were significantly different among the three TCM syndromes of diabetic nephropathy group (X2 = 8.700, P = 0.013; X2 = 6.591P = 0.037); and the gene frequencies of GA + AA and A alleles were all: deficiency of both yin and Yang type of Qi and yin. The distribution of GA + AA genotype of deficiency of both spleen and Kidney Yang was compared between the two groups. The difference between deficiency of both qi and Yin and deficiency of spleen and Kidney Yang was statistically significant (X2 = 6.551, P = 0.01). The difference between deficiency of both yin and Yang and deficiency of spleen and Kidney Yang was statistically significant (X2 = 6.866, P 0.01). X2 = 0.015, P 0.05); G-395A allele frequency distribution of each two groups were compared, the difference between Qi-yin deficiency group and spleen-kidney Yang deficiency group was statistically significant (X2 = 4.73, P 0.05), the difference between Yin-yang deficiency group and spleen-kidney Yang deficiency group was statistically significant (X2 = 4.86, P 0.05), and the difference between Qi-yin deficiency group and yin-yang deficiency group was not statistically significant (P 0.05). 4. There was a significant difference in the degree of edema among DN patients with different genotypes and alleles (Z = 2.951, P = 0.003; Z = 2.549, P = 0.011). There was no significant correlation between G-39A polymorphism and the severity of symptoms such as fatigue, lumbar and knee soreness, and abnormal appetite (P 0.05). Results 5, 16 randomized controlled trials were included. A total of 1107 patients with diabetic nephropathy were enrolled in this study. The results of Meta-analysis showed that the experimental group mainly treated with Wenyang Huoxue Lishui was more effective than the control group (RR = 1.97,95% CI 1.50-2.59, Z = 4.86, P 0.00001; RR = 1.48,95% CI 1.35-1.62, Z = 8.58, P 0.00001); and the experimental group decreased the blood and muscle compared with the control group. MD = - 32.33, 95% CI - 58.20 - 6.47, Z = 2.45, P = 0.01; MD = - 2.20, 95% CI - 4.13 - 0.26, Z = 2.22, P = 0.03; MD = - 32.33, 95% CI - 58.20 - 6.47, Z = 2.45, P = 2.45, P = 0.01; MD = - 2.20, 95% CI - 4.13 - 0.26, Z = 2.22, Z = 2.22, P = 0.03); higher HD-HD-LDwas better (MD = 0.16, 95% CI 0.16, 95% CI 0.09-0.09-0.23, Z = 4.33, Z = 4.33, P 0.0001); lower cholestero, triZ = 3.49, P = 0.0005; MD = - 0 40,95% CI-0.53-0.53-0.26,Z=5.95,P=5.95,P 0.00001;MD=-0.49,95% CI-0.76-0.21,Z=3.46,P=0.0005;MD=-0.46,95% CI-0.53-0.53-0.26,Z=5.53-0.25,Z=5.95% CI-0.53-0.25,P=0.000 1;MD=-0.40,95% CI-0.49,95% CI-0.95% CI-0.76-0.76-0.21,Z=3.46,P=0.0005;urinprotein reduction effect was more obvious (MD =-0.46,95% CI-0.46,=-0.31, 95% CI-0.50-0.12, Z = 3.15, P = 0.002) Conclusion 1. The distribution of G-395A genotypes in Hubei Han population is well representative, F352V and C370S polymorphisms are rare. 2. There is no association between G-395A polymorphisms and the risk of type 2 diabetes mellitus. 95A polymorphism is not associated with the severity of diabetic nephropathy; the presence of allele A may increase the risk of kidney damage in type 2 diabetes mellitus; carrying allele A may be an independent risk factor for renal complications in type 2 diabetes mellitus in Hubei Han population, while heterozygous GA and homozygous AA genotype may be. At the same time, glycosylated hemoglobin, duration of diabetes and history of hypertension may be independent risk factors for type 2 diabetic nephropathy. 3, GA and AA genotypes may be susceptible genotypes of diabetic nephropathy patients with spleen and kidney yang deficiency, and diabetic nephropathy patients with allele A may be susceptible. A allele may be one of the risk factors of diabetic nephropathy with spleen-kidney Yang deficiency. 4. GA and AA genotypes may be the susceptible genotypes of diabetic nephropathy with severe edema. Diabetic nephropathy patients with A allele may be more susceptible to edema aggravation. 5. Warming Yang, activating blood circulation and eliminating water therapy is the main method. The experimental group of integrated traditional Chinese and Western medicine is better than the control group in the treatment of diabetic nephropathy. It can not only reduce the levels of serum creatinine and urea nitrogen, but also reduce urinary protein, regulate the abnormal metabolism of lipids and improve blood sugar. But it has the same effect in improving inflammation. Good, worthy of clinical application.
