Insulin resistance and insulin secretion deficiency are main machanisms in inducing type 2 diabetes mellitus (T2DM), and mitochondria damage plays an important role in them. Research shows that autophagy is a self-protective mechanism of cells, which plays an important role in maintaining the normal structure and function of pancreatic β cells and improving insulin resistance. Previous studies show that traditional Chinese medicine can regulate cell autophagy to influence β cells and insulin resistance, type 2 diabetes mellitus and its complications. Thus this review will talk about the process of the relationship between autophagy and T2DM and the intervention effect of traditional Chinese medicine.

The influence of medium variety、thermal treatment of the soil samples and inhibitor to the isolation effect of actinomycetes was studied by plate paint isolation methods.The results showed that: ①The isolation results of gauze No.1(GA) and straw decay substance agar(SDSA) might reflect basic station of soil actinomycetes. ②Thermal treatment (120℃?1.0h)in soils might promote actinomycetes spore sprouting and increase the quantity and variety of actinomycetes. The quantity and varieties of actinomycetes in the Soils that were treated with 120℃?1.0h were increased by 5.5%～54.9% and 12.5%～100% than the check of none-thermal treatment respectively. But thermal treatment had no effect on reduce the quantity of bacteria. ③The quantity of bacteria had significant reduction by adding 75?g/mL K 2Cr 2O 7 and 1～3?g/mL penicillin at same time to the isolation medium, and had little effect on the quantity and varieties of actinomycetes. Actinomycetes quantity (?10 6cfu/g) and variety of the treating of 75?g/mL K 2Cr 2O 7 and 1～3?g/mL penicillin in No.1 soil on SDSA medium had reductions by 0～58.8% and 0～18.2% compared with treating of 75?g/mL K 2Cr 2O 7, respectively. ④streptomycin might not been used for bacterteria inhabitor in the isolation of actinomycetes.

To set up a new method of detecting bacterial number in situ,NADH fluorescence method based on the fluorescent characteristic of NADH was used.When the concentration of NADH ranged from 10 nmol/L to 0.2 mmol/L,its concentration had a good line relationship to the fluorescence intensity(R2= 0.9905).Separating bacterial cells by centrifugation and extracting NADH with hot Tris-HCl buffer,the re-sult of bacterial count detected with NADH standard plot was 1?104 CFU/mL in an hour.In summary,NADH fluorescence method is rapid,sensitive,simple and reliable to detect total bacterial number.There-fore,the method can be widely applied in the field of food sanitation and safety,environment detection and so on.

Objective To observe the expression of Na+/I- symporter(NIS) in cultured lactating mammary cells with different levels of iodine and the effect of tumor necrosis factor-α(TNF-α). Methods Original generation of mouse lactating mammary cells cultured in vitro were divided into low iodine group Ⅰ (LI-Ⅰ), low iodine group Ⅱ (LI-Ⅱ), adequate iodine group(AI), high iodine group Ⅰ(HI-Ⅰ), and high iodine group Ⅱ(HI-Ⅱ). Cells were cultured in DEME/F12 culture medium for 24 h with different concentrations of iodine (0,5,50,3000 and 10 000 μg/L, respectively), and TNF-α( 10-2 mg/L) was added to some of cultured cells for 24 h. The expression of NIS mRNA of lactating mammary cells was determined by real-time quantitative PCR and the expression of NIS protein was detected by In-Cell Western. Results In iodine alone group, the expression of NIS mRNA in LI-Ⅰ group [ (64.66 ± 14.99) x 10-4] was higher than that of AI group[ (22.76 ± 7.36) × 10-4, P ＜ 0.01 ]; HI-I group[ (10.18 ±3.53) × 10-4] and HI-Ⅱ group[ (8.59 ± 2.89) × 10-4] were lower than that of AI group(all P ＜ .0.05); With increased iodine concentration, the expression of NIS mRNA decreased. The expression of NIS mRNA in LI-Ⅰ group [(2.72 ± 0.45) × 10-4], LI-Ⅱ group[ (2.69 ± 0.68) × 10-4] and AI group[(1.80 ± 0.67) × 10-4] with iodine plus TNF-o were all lower than that of LI-Ⅰ group, LI-Ⅱ group[ (29.82 ± 4.47 ) × 10-4], and AI group without TNF-α (all P ＜ 0.01). In iodine plus TNF-α, the expression of NIS mRNA in HI-Ⅰ group[(6.58 ± 2.87) × 10-4] and HI-Ⅱ[(7.04 ± 1.36) × 10-4] group were all higher than that of AI group(all P ＜ 0.05); With increased iodine deficiency or iodine excess, the expression of NIS mRNA increased. With increased iodine concentration, the expression of NIS protein decreased in iodine alone group. The expression of NIS protein in iodine plus TNF-α was all lower than that in iodine alone group. In iodine plus TNF-α, the expression of NIS protein increased in both iodine deficiency and iodine excess conditions. Conclusions Iodine may decrease the expression of NIS mRNA and protein of lactating mammary cells. The expression of NIS mRNA and protein of lactating mammary cells was inhibited by TNF-α under different levels of iodine.

ObjectiveTo study the morphological and functional changes of thyroid in lactating rats and their offspring in iodine deficiency and iodine excess animal models.MethodsOne hundred and twenty Wistar rats(30 males and 90 females) were selected.Based on their body weight,the 90 females were stratified and randomly divided into five groups( 18 in each group):low iodine group 1 and group 2(fed with low iodine feed and deionized water containing iodine of 0,5 μg/L) ; high iodine group 1,group 2 and control group(feed with normal diet and deionized water containing iodine of 3000,10 000,50 μg/L).After fed for 3 month,all female rats were mated with males in a ratio of 3 ∶ 1.After birth for 10 days,8 female rats and their offspring in each group were sacrificed.Changes of thyroid were observed by naked eyes.The thyroid weight was measured and pathological changes of thyroids were observed under light microscope.Results①Absolute and relative weight of lactating rats thyroid in low iodine group 1 and group 2 [ (92.02 ± 24.40 ),(77.11 ± 23.32 )mg,(0.509 ± 0.072),(0.384 ± 0.089) mg/kg] were much higher than that of control group[ (17.41 ± 9.25)mg,(0.102 ± 0.016)mg/kg,all P＜ 0.05].Absolute and relative weight of lactating rats thyroid in high iodine group 1 and group 2[(8.22 ± 0.41 ),(9.42 ±0.43)mg,(0.047 ± 0.006),(0.035 ± 0.005)mg/kg] were lower than that of control group(all P ＜ 0.05).Absolute and relative weight of lactating rats and their offspring thyroid was decreased with increase of iodide intake in the diet.②Thyroid enlargement of lactating rats in low iodine group 1 and group 2 was evident,but that of high iodine group 1 and group 2 was not.③Epithelial cell hyperplasia and smaller follicular cavity were observed in low iodine group 1 and group 2 under light microscope.Epithelial cell deformation and mostly flat were observed in high iodine group 1 and group 2.ConclusionsThyroid morphology is changed with iodide intake in the lactating rats and their offspring,and the changes are consistent between female rats and their newborns.
