UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.

Objective To investigate the effect of up-regulating miR-34c-5p on cloning formation and migration of nasopharyngeal carcinoma cell line HONE-1 in vitro. Methods Expression levels of miR-34c-5p in nasopharyngeal cell line NP69 and nasopharyngeal carcinoma cell line HONE-1 were investigated by real time quantitative PCR;Cloning Forma?tion Test and Transwell Migration Assay were used to explore the effect of up-regulating miR-34c-5p on proliferation and migration of nasopharyngeal carcinoma cell line HONE-1. Results The expression of miR-34c-5p in nasopharyngeal car?cinoma cell line HONE-1 was lower than that in normal nasopharyngeal cell line NP69. Up-regulating miR-34c-5p signifi?cantly suppressed the cloning formation and migration capacity, compared to those of NP69 cell line and HONE-1 with nor?mal level of miR-34c-5p(P<0.05). Conclusion Down-regulating miR-34c-5p involve in proliferation and migration of nasopharyngeal carcinoma and may be a used as a new therapeutic target for nasopharyngeal carcinoma.

Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.

Objective To investigate the distribution of water-borne fluoride and the current situation of endemic fluorosis in Yan'an city in 2006, and to evaluate the effect of water defluoridation project by improving driking water quality. Method In 2006 in Yan'an city, 5 samples from water source were collected in each selected village that was chosen according to 5 directions of East, West, South, North, and Central. Meanwhile, 1 sample from water source, 1 sample from water processing factory and 2 tap water samples were collected from each water defluoridation project. Water fluoride was determined by spectrophotometric method, teeth and skeletal fluorosis examination were performed by Dean method and "national criteria of endemic skeletal fluorosis diagnosis of China" in children aged 8-12 year and adults, respectively if water fluoride level > 1.00 mg/L Results Of 726 water samples from 293 villages tested, samples from 25 villages had higher fluoride( > 1.00 mg/L), and these villages covered a population of 11 610 people and most of these people were in Wuqi and Yanchuan counties. Water fluoride ranged from 0.10 mg/L to 3.50 mg/L, with median being 0.59 mg/L. Of 100 water samples from 25 water defluoridation projects, only 1 sample exceeded the national criteria in Yanchuan, and Wuqi counties, respectively,with fluoride level being 1.85 mg/L and 1.60 mg/L, respectively, and population exposed was 3083 and 708, respectively, with water fluoride ranged 0.30 - 2.00 mg/L In the examination of 1281 children aged 8 - 12, we detected 238 cases of dental fluorosis, and the detection rate reached 18.58%; 13 900 adults were checked, and 375 cases were confirmed of skeletal fluorosis, a detection rate reached 2.70%. Conclusions Yan'an has a wide range of water with high fluoride and severe fluorosis people. The water defluoridation projects need to be further improved. The task of prevention of endemic fluorosis is still arduous, and we should speed up the implementation of comprehensive water defluoridation measures.

Objective To study the effects of different levels of iodine concentration on insulin-like growth factors Ⅰ (IGF-1) mRNA expression of thyroid and breast in lactating rats. Methods Thirty Wistar female rats, having been weaned for 1 month, were randomly divided into three groups according to their body weights, i. e. :low iodine(LI) group,adequate iodine(AI) group, high iodine(HI) group, 10 rats in each group. Synthetic fodder and deionized water containing iodine of 0,150,3000 μg/L was respectively fed to these rats. After fed for 3 months, the rats mated and had offspring. Their mammary glands, thyroids and serum were sampled at lactation day 5. The serum iodine of lactating rats were determined by moderate acid digestion method, level of T3 and T4 were determined by radioimmunoassay method, and the expressions of IGF-1 mRNA of mammary glands and thyroids were determined by real-time fluorescence quantitative PCR assay. Results The value of serum iodine of LI group [(17.38±3.27) μg/L] was lower than that of AI group [(43.42±6.92) μg/L, P<0.05], and the value of serum iodine of HI group[(350.10±38.46)μg/L] was higher than that of AI group (P<0.05). The level of T3 of LI group and HI group[ (1.11±0.25), (1.61±0.33)μg/L] reduced obviously compared with that of AI group[(2.18±0.46) μg/L, P<0.05]. The mean of T4 of LI group and HI group[(33.40±11.11),(56.54±10.38)μg/L] had no statistical significance compared with AI group(44.02±12.51)μg/L, P>0.05), but the level of T4 of LI group was lower than that of HI group(P<0.05). The level of IGF-1 mRNA expression of thyroid in LI group and HI group (0.34±0.08, 0.23±0.08) was higher than that of AI group(0.15±0.03, P<0.05). The level of IGF-1 mRNA expression of lactating mammary in LI group(0.59±0.18) was higher than that of AI group(0.40±0.10, P<0.05). The level of IGF-1 mRNA expression of thyroid was lower than that of breast between the same group(t=3.54, 6.44,2.62, all P<0.05). Conclusion Iodine could affect IGF-1 mRNA expression of thyroid and lactating mammary, and IGF-1 mRNA expression of lactating mammary was stronger than that of the thyroid.

Background Placement of an orbital implant is a main way to prevent orbital atrophy with aging.But its mechanism is under clear.Researchs showed that bone growth factors play important role during the development and repair of bone,especially transforming growth factor-β1(TGF-β1).Objective Present study was to investigate the expression of TGF-β1 protein in orbital bone after enucleation or enucleation with placement of an orbital implant and its function in the mechanisms of preventing and treating the orbital malformed development after enucleation with placement of an orbital implant.Methods Twenty-one age- and weight-matched New Zealand white young rabbits were randomly divided into the enucleation,implant and control groups,and each group including seven rabbits.Eyeball nucleation surgery was performed in the left eyes of 7 1-month-old rabbits,and a spherical orbital implant was inserted after enucleation of the left in matched rabbits in implant group.The left eye of normal rabbits served as controls.The rabbits were sacrificed in 1 month after surgery.The expression of TGF-β1 protein in the left orbital bone was detected using enzyme immunoassay and FITC labelling immunoassay technique in the sections of zygomatic bones.The content of TGF-β1 protein in the left orbital bone tissue was measured by ELISA method.This use of animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The height and width of orbital in enucleation group were significantly lower than those of implant and normal control groups(height:P=0.00,P=0.00;width:P =0.00,P=0.00).The positive bone cells of both enzyme immunoassay and FITC staining were increased in the implant and control groups in comparison with enucleation group,but the positive response intensity for TGF-β1 was resembled between implant group and control group.ELISA result revealed that the content of TGF-β1 protein in bone tissue was significantly lower in the enucleation group than in implant and control groups(P=0.00,P=0.00).The expression and content of TGF-β1 protein in bone tissue is similar between the implant group and the control group(P=0.41). Conclusion The experiment results indicate that TGF-β1 protein participate in the orbital development.TGF-β1 played important role in the prevention and treatment of enucleation-induced orbital malformation in the eye with placement of an orbital implant.
