Objective: To study expression of CD44 S and CD44 V6 in ameloblastoma (AB) and odontogenic keratocyst (OKC) . Methods: S-P method was used to detect CD44 S protein in 77 cases of AB (32 of primary, 39 of recurrent,6 of malignant), 19 cases of OKC and 12 cases of oral normal mucosa;and CD44 V6 protein in 61 cases of AB (24 of primary , 31 of recurrent and 6 of malignant), 19 cases of OKC and 12 cases of oral normal mucosa. Results: Expression of CD44 S and CD44 V6 were detected in cell membrane of stratum spinosum and stratum basale in normal oral mucosa. In 19 cases of OKC, loss of expression of CD44 S was detected in 10 cases, and loss of integrity of CD44 V6 expression was detected in 15 cases. Loss ration of expression and abnormal expression ratio of CD44 S in AB were 27.3% and 63.6%, respectively. That of CD44 V6 in AB were 11.5% and 50.8% respectively. There was a signifcant difference between loss of expression or abnormal expression of CD44 S and CD44 V6 in AB, OKC and normal oral mucosa (P

Objective To isolate and culture the rabbit mesenchymal stem cells,and explore the biological features in vitro.Methods Two milliliter of bone marrow was extracted from the tibia of juvenile rabbit under anesthesia and sterile conditions,and mesenchymal stem cells were obtained by density gradient centrifugation and inoculated to 100ml culture flask.The morphological changes,adherence rate and ultrastructure of the stem cells were observed.The surface markers and growth cycle of the mesenchymal stem cells were detected by flow cytometry,and biological features were observed by inducing the cells differentiate into osteoblasts.Results The adherence of mesenchymal stem cells started 2 hours after culturing,basically finished 20 hours later,and more than 90% of the cells were fused at the 15th day.Observed with transmission electron microscopy,the cultured cells showed typical ultrastructure of stem cells: numbers of microvillus mainly distributed on one side of the cells,irregular nuclei with indentation,and lots of cell organs.Analysis for the cell surface markers indicated positive expression of CD44 and CD90 and negative expression of CD45 in mesenchymal stem cells.Cell growth cycle assay showed that most mesenchymal stem cells(about 97%) stayed in stage G1 and G2.Three weeks after osteoblastic induction,the mesenchymal stem cells gradually produced small calcium salt crystals,the cells were positive in alkaline phosphatase staining,and Von Kossa staining showed many calcium salts in the cell clone as black reaction deposits.Conclusions The rabbit bone marrow mesenchymal stem cells isolated by density gradient centrifugation are of high purity and stable growth rate,and the cells' characters can be still maintained after serial subcultivation.Since easy to operate on isolation and proliferation,the mesenchymal stem cells could be used as the tissue engineering seed cells in repairing of intervertebral disc degeneration.

Objective To analyze the population genetics of two outbred colony guinea pigs from two institutions and provide basical information in developing genetic detection methods and standardization of the outbred guinea pigs.Methods 25 polymorphic microsatellite markers were screened by a fluorescent based semi-automated genotyping method for the two populations of guinea pigs, and the population genetic parameters were calculated.Results A total of 121 alleles were detected in the two populations, with 2-10 alleles and a mean 4.84 alleles at each locus.The mean expected heterozygosity was 0.6067, and the average polymorphism information content was 0.552.In the two populations, 103 and 116 alleles were detected, the mean expected heterozygosity was 0.5195 and 0.5838, and mean polymorphism information content was 0.459 and 0.518, respectively.Five loci and six loci, respectively, showed significant deviation from Hardy-Weinberg equilibrium (P<0.05) in the two populations, mostly resulted from heterozygote deficiency.The average Fst of all loci was 0.1056, which implied a moderate genetic differentiation between populations.The Nei’ (1972) genetic distance and Nei ‘(1978) unbiased genetic distance between the two populations were 0.3302 and 0.3204, respectively.Conclusions Both the two populations are consistent with a closed group of animal population genetic characteristics.Several loci deviate from HWE, which probably indicates that a certain degree of inbreeding phenomenon exists during the breeding process.

Objective To screen the markers of chromosome 12, which is vacant in the Beijing local standard DB11/T828.3-2011 for genetic quality control of miniature pigs in Beijing, and to study the applicability of the local standard by comparison of two different methods for evaluation of the genetic quality of the same population.Methods According to the literature, we selected four pairs of microsatellite markers of chromosome 12 and studied the polymorphism through monitoring the genetic quality of two populations of China Agricultural University miniature pigs.We screened the highly polymorphic markers of chromosome 12, combined them with the microsatellite primers of the standard 18 pairs of chromosomes to establish the whole chromosome method.We compared and analyzed the applicability of the local standard DB11/T828.3-2011 through monitoring the genetic quality of the same population of miniature pigs with different method.The data were processed and analyzed using software Popgen32.Results All the screened four pairs of microsatellite markers of chromosome 12 were highly polymorphic (PIC>0.5).The local standard showed a chromosome coverage of 94.7%, stability of amplification of 96.0%, and certified that the China Agricultural University miniature pig III was qualified, while the China Agricultural University miniature pig I was not qualified.When the markers of chromosome 12 were added, the whole chromosome method showed result of 100% chromosome coverage and 96.6% amplification stability, both of the two populations of pigs were certified as qualified.Conclusions The four screened markers of chromosome 12 are all highly polymorphic, and provide a support for supplement of the local standard DB11/T828.3-2011.

Objective To discover the reciprocal regulation and its molecular mechanism of estro-gen, IL-6 and IL-8 in ovarian cancer cells. Methods Based on our previous studies, the effect of 17β-estradiol (E2) on the expression levels of IL-6, IL-8 and their respective receptors was investigated. Mean-while, the effect of IL-6/IL-8 on estrogen receptor (ER) expression and estrogen-dependent transcriptional activation was analyzed. Gene expression profile analysis revealed that CAOV-3 and OVCAR-3 cells, which express ER, IL-6 and IL-8 receptors, were suitable models for this study. Results We found that E2 not only enhanced IL-6/IL-8 secretion via NF-κB signaling pathway, but also modulated IL-6 and IL-8 receptors expression. Tamoxifen (Txf), an ER antagonist, completely abolished E2-stimulated IL-6/IL-8 expression. On the other hand, in the absence of estrogen, both cytokines increased ERα expression, decreased ERβ ex-pression, and activated estrogen-dependent transcriptional activation, which was completely blocked by Txf. Pretreatment of OVCAR-3 with p38 MAPK, MEK1/2 or ErbB2 MAPK inhihitors, respectively, IL-6-media-ted ER activation was blocked, while IL-8-indueed ER activation was blocked by Src inhibitor. Conclusion These data suggest that estrogen, IL-6 and IL-8 may form a mutual amplifying signaling which contributes to the growth and development of ovarian carcinoma.

ObjectiveTo explore the relationship between diet habits and constitution type of 8448adults from 9 provinces and municipalities of China.MethodsA total of 8448 participants from Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and Henan Province were enrolled in this study.The clinical information of constitution type,diet habits and demographic characteristics was collected.Logistic regression analysis was used to evaluate the relationship between diet habits and constitution type.ResultsLogistic regression analysis showed that gentleness type and Qi-deficiency were correlated with sweet food ( OR =1.22,P ＜ 0.05 ). There was a significantly positive correlation between Yangdeficiency and hot food intake ( OR =2.89,P ＜ 0.05 ),as well as between Yin-deficiency and cold food intake ( OR =1.56,P ＜ 0.05).Phlegm-wetness was mainly caused by fatty food consumption ( OR =2.07,P ＜ 0.05 ).Barbecue food was positively correlated with Wet-heat type ( OR =1.64,P ＜ 0.05 ),Bloodstasis type ( OR =1.37,P ＜ 0.05 ),and Qi-depression type ( OR =1.35,P ＜ 0.05 ).Special diathesis type was related to dietary preference of sweet food ( OR =1.29,P ＜ 0.05 ).ConclusionDifferent type of constitution may be related to specific lifestyle or diet habits,and diet habit might play a positive role in Gentleness type or health condition.
