[Clinical implication of urinary protein markers in diabetic nephropathy and interventional effects of Chinese herbal medicine].

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.

[Characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy and its regression analysis with traditional Chinese medicine symptom].

To analyze the characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy (DN) and its compliance with traditional Chinese medicine (TCM)symptom, for the sake of providing a basis for clarifying the rules of TCM syndrome differentiation in DN. Adopting the traditional epidemiological retrospective method, thirty-eight TCM syndromes and urinary protein with medium or low molecular weight, as well as urinary enzyme, including 24 h urinary protein (Upro), urinary albumin( UAlb), urinary retinal binding protein( URBP), urinary cystatin C (UCysC), urinary N-acetyl-beta-D-glucosaminidase (UNAG), were collected from 108 patients with stage III DN, and a multiple factor regression analysis between them was conducted. As the results, the levels of Upro, UAlb, URBP, UCysC, and UNAG were increased in 108 patients with stage III DN. Qi-Yin deficiency type was the major type. The level of UAlb in patients with Qi-Yin deficiency type was significantly higher than those without Qi-Yin deficiency type (P < 0.05). The elevation of Upro with the factors as swift digestion with rapid hungering, lassitude and lack of strength, weakness of waist and knees was complied, the elevation of UA1b with the factors as dry mouth with desire to drink, the elevation of URBP with the factors as numbness of extremities, shortness of breath, the elevation of UCysC with the factors as clear urine in large amounts, and the elevation of UNAG with the factors as frequent micturition, were complied respectively. In conclusion, for 108 stage III DN patients. The increase in urinary protein spectrum including UAlb, URBP, UCysC, and UNAG is the major characteristic. Shen and Pi are the major organs related to the appearance of urinary protein; Pi-Shen deficiency is the basic pathogenesis. The level of UAlb is taken as one of the objective syndrome factors for Qi-Yin deficiency type. The levels of UNAG and UCysC are possibly the objective syndrome factors for Shen-Qi deficiency type.

[The associated study on apolipoprotein A5 gene polymorphisms with carotid artherosclerosis in patients with cerebral infartion].

OBJECTIVE: To investigate the association of -1131T>C and c.553G>T polymorphisms and their haplotypes in apolipoprotein A5(ApoA5) gene with cereberovascular disease in Chinese. METHODS: Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), we analyzed two ApoA5 genetic variants in 272 patients with cerebral infarction (CI) and 316 control individuals respectively. The levels of serum lipid profiles were measured with biochemical methodsìand the other clinical characters were obtained by case file investigation. RESULTS: The odds ratio (OR) for CI in -1131CC genotype carriers was 2.10 (95%CI 1.01-4.37). The distribution of T-T and T-G haplotypes had obvious differences between CI patients and control individuals. The OR for CI in C-G and T-G haplotype carriers were 1.34 and 0.71(95% CI 1.02-1.76 and 0.55-0.92) respectively, compared with the others. Furthermore, the major haplotypes had significant differences of serum TG(P< 0.05). CONCLUSION: The ApoA5 -1131T>C polymorphism may be associated with an increased risk of CI in the Chinese population, but the influence of blood lipids can not be ignored.
