RESUMO
OBJECTIVE: To analyze the levels of homocysteine, 9 kinds of vitamins including folic acid in patients with type 2 diabetes mellitus, so as to provide basis for the early detection and intervention of diabetic nephropathy. METHODSE: A total of 416 patients with type 2 diabetes were divided into nephrotic group and non-nephrotic groups, and subjects were included in the same period of physical examination as the physical examination group. The elderly physical examination group was selected by age. The serum homocysteine (Hcy), folic acid and vitamin (Vit) A, D, E, B1, B2, B6, B12 and C levels of all subjects were collected retrospectively. Differences between different groups were analyzed by ANOVA, and Pearson correlation analysis was used to analyze the correlation between different index levels and GFR or ACR. RESULTS: The levels of folic acid, and Vit D, B1, B2, B12 and C in the disease groups were significantly different from those in the physical examination group, but only Vit D levels decreased and Vit B12 levels increased comparing with those in the elderly physical examination group (P<0.05). There were differences in Hcy, and Vit A, D, E and B6 levels between nephrotic group and non-nephrotic group (P<0.05). The changes of these indexes may be related to the occurrence of nephrosis, but the influence of age cannot be excluded. Hcy, Vit A and D levels were significantly correlated with GFR and ACR (P<0.01). CONCLUSION: Hcy is related to the occurrence of nephropathy, which may be a reference index for early detection of diabetic nephropathy. Folic acid, Vit B2, B6, B12, C and other water-soluble vitamins have been taken as supplymentin diabetic patients. Fat soluble such as Vit A, D, and E also related to the occurrence of nephropathy in varying degrees, and the supplement of these vitamins may benefit.

RESUMO
ABSTRACT Context The rizoma of Sparganium stoloniferum has been used as a traditional Chinese medicinal herb for thousands of years. Sparganium stoloniferum is a stasis-breaking drug to treat a wide range of diseases including cancer,however, its activity of extract on cervical cancer HeLa cells and the mechanisms remains unknown. Objective This study aimed to screen Sparganium stoloniferum extract for its inhibitory effects on cervical cancer HeLa cells. Materials and methods Sparganium stoloniferum was extracted with 95% ethanol under reflux, and the extracts were preliminary separated by silica gel column chromatography. MTT assay and flow cytometry were used to determine the inhibitory effects of three fractions on HeLa cells. In addition, GC-MS was performed to analyze the chemical composition of the active fraction. Results Sample II showed a dose-dependent inhibition of HeLa cell growth, with an inhibition rate of more than 30%, whereas the inhibition rates of Samples I and III were less than 30%. Interestingly, Samples I and III had no effect on apoptosis, in contrast to Sample II, which significantly promoted HeLa cell apoptosis, in a dose-dependent manner. GC-MS was performed to analyze the chemical components of Sample II: steroids were found to be the major components with a relative content of 73.905%, while six known compounds were obtained for the first time. Discussion and conclusion This study provided a novel insight for further research of active fractions of Sparganium stoloniferum, in accordance with the basic principle and theory of traditional Chinese medicine (TCM), and will promote the shift of effective substance study, from monomeric chemical compounds to active fractions.
