Objective To study the relationship between T~(-786)→C mutation in the 5′-flanking region of the endothelial nitric oxide synthase gene and type 2 diabetes(T2DM) with coronary heart disease(CHD). Methods One hundred and eighty-six T2DM were selected,and of them,65 had CHD.Meanwhile,63 healthy individuals were selected as control.PCR/ASO(allele-specific oligonucleotide probe) technique was used to determine the T~(-786)→C mutation.Results Compared with control,the T/C genotype and C allele prevalences were significantly higher in T2DM with CHD(P

Objective To explore the intrinsic link between neuro-endocrine-immune (NEI) network and the viscera-state.Methods Using three databases namely TCM database, Chinese pharmacy database and combination of TCM and WM database in China Academic Journals Database, the authors searched and collected NEI-related indicators published on journals for the viscera-state researches. Then a related database was established for data mining. Through analysis of association rules, analysis of the relationship among diseases, syndromes, therapeutic principles, combination of disease and syndrome, and NEI network related indicators were performed for association rules and directional network diagrams.Results Through the association analysis, the authors drew 44 directional network diagrams of high-frequency disease positions, syndromes, therapeutic principles and NEI network related indicators, and obtained 19 association rules. Kidney and liver essence research focused on HPG axis, HPA axis, and HPT axis. Spleen essence research focused on brain-gut peptide related indicators. Heart essence research focused on vascular endothelium function indicators. Pulmonary essence research focused on humeral immunity, ET and TNF-α.Conclusion It was feasible to explore the intrinsic link between NEI network and the viscera-state by using data mining. Differences among study on NEI network of five-organs systems were found, which is of great significance for researches on the essence of the viscera-state.

Background Perineural invasion is an important biological character for adenoid cystic carcinoma (ACC) of lacrimal gland,which is different from those of other lacrimal gland tumors.As the important part of neurotrophic factors,glial-derived neurotrophic factor (GDNF) plays an important role in perineural invasion for ACC of salivary gland.GDNF regulation in the ACC cell biology function needs to be further explored.Objective This study was to investigate the effect of GDNF on proliferation and migration of ACC cells,and to explore the mechanism of neural invasion in ACC of lacrimal gland.Methods ACC-2 cell line was cultured and passaged in RPMI 1640 medium with 10% fetal bovine serum,100 U/ml penicillin and 0.1 g/L streptomycin.Single-cell suspension was prepared with the density of 2×104/ml using logarithmic phase of cells and then incubated to 96-well plate.GDNF with the final concentration of 20,60,80,100 and 120 μg/L was added into the medium respectively in the experimental groups,and the cells were cultured in the medium without GDNF as the control group.The expression of GDNF in ACC-2 cells was detected by immunohistochemistry.MTT assay was employed to assay the absorbance value at the wavelength of 570 nm (A570) for the evaluation of proliferation of ACC-2 cells after cultured by different concentrations of GDNF for different time points.Meanwhile,transwell chamber was used to examine the cell migrated number.Results Immunochemistry assay exhibited that ACC-2 cells showed the positive response for GDNF with the brown staining in the cytoplasm.In 48 hours after culture,the A570 value was elevated with the increase of GDNF concentration,showing a significant difference among various groups (F =3.336,P =0.026),and the A570 value in various concentrations of GDNF groups was higher than that of 0 μg/L GDNF group (all P<0.05).After action of 80 μg/L GDNF,the A570 value of the cells was gradually increased with the prolong of culture time (Ftime =39.979,P=0.000).In 30 minutes after GDNF cultured,the number of migrated cells increased with the increase of GDNF concentration (F=144.886,P=0.000).ACC-2 cells were cultured by 100 μg/L GDNF for 24,30 and 40 hours,the number of migrated cells were more as the time lapse,and more migrated cells were seen in GDNF group at various time points (Ftime =46.747,P =0.000 ; Fgroup =63.786,P =0.000).Conclusions GDNF can stimulate the proliferation and migration of ACC-2 cells in a dose-and time-dependent manner.

Objective This study was designed to explore the effect of hyperglycemia on the expression of Toll-like receptor 4 (TLR4 ) in renal tubular epithelial cells and its significance in diabetic nephropathy. Methods In vitro cultured renal tubular epithelial cells ( NRK-52E) were divided into LG group (cultured in 5mmol / L glucose DMEM) and HC group (cultured in 25mmol / L glucose DMEM). Cells were harvested at different time points. Immunohistochemistry, Rt-PCR, Western Blot were used to detect TLR4 protein and mRNA expression, and the levels of IL-6 and TNF-α from the cell culture supernatant were determined by EL1SA assay. Results After 6 hours, there was increased expression TLR4 mRNA in HC group, which appeared to be maintained for 24 hours and began to decrease after 48 hours ( P < 0.05). TLR4 protein expression increased in HC group after 24 hours, and increased even further after 48 hours. Compared with LG groups, the difference had statistical significance ( P <0.05). In HG group, IL-6 and TNF-α expression in the supernatant from the NRK-52E culture were significantly increased ( P < 0.05) , and the expression of IL-6 and TNF-α was positive correlated with the expression of TLR4 protein ( r =0.799,0.820). Conclusion High glucose triggers an increase in expression of TLR4 in NRK-52E cells, itself leading to an increase in expression of inflammatory factors such as TNF-α and IL-6. In this way, TLR4 participates in the progress of diabetic nephropathy.
