Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

To explore the impact of Salmonella on Enterococcusfaecalis isolate N41 under the coexisting,the growth traits and the transcription of 26 virulence genes of N41 at various growth phases were detected.Salmonella and/or N41 were inoculated and done plate counting,then growth curves were drawn and bacterial total RNA were extracted at given time points,quantitive realtime PCR was used to analyze the RNA transcription levels of 26 virulence genes of N41.The result showed that comparison with single incubation,the bacteria concentration of N41 dropped about 3.9 times,and Salmonella dropped about 110-times.Among 26 virulence genes of N41,the RNA transcription levels of 12 virulence genes such as ebpA,ebpC,rnjB,ace,ebpR,psr and so on were promoted at the four growth phases,but the RNA transcription levels of SlyA and sprE were dropped.Except that the RNA transcription levels of CylL-S,CylL-L,efaA and AS had no significant changes at the four growth phases,the mostly rest genes increased dramatically at post-log phase.This indicated that when incubated together,N41 inhibited the growth of Salmonella significantly,and Salmonella promoted the transcription levels of virulence genes of N41 as a whole.The results lay a foundation for further research on the interaction between bacteria species and the pathogenicity mechanism of Enterococci.

Animal medicine is an important part of traditional Chinese medicine with a long application history in China. Systematically understanding the history of the development of animal medicine is of great significance to scientific protection and rational use of animal medicine resources. It has certain guiding significance to protection of wild resources, exploitation of new substitutes, standardization and summary of artificial breeding, and artificial reproduction technology. Taking the development of bezoar as an example, this article expounded the following four aspects:the development history of animal medicine, national animal protection, technical development, and prospect forecast by summarizing the Chinese ancient medical books and consulting the relevant laws and regulations. The entire above are about to offer new ideas for the sustainable development, the development of new medicine resources, and the development of animal medicine related preparation product.

AIMTo investigate the distribution of c-myb, an oncoprotein, in mouse oocytes-cumulus cell complex and sperm immunohistochemically.

METHODSTo study the effect of c-myb on mouse fertilization in vitro, various concentration of c-myb antisense-oligodeoxynucleotides (c-myb ASODNs) were incubated with sperms and oocytes during fertilization. To explore the possible mechanism involved in fertilization, the relationship between c-myb ASODNs and GABA or dbcAMP or Verapamil or Progesterone in fertilization was also observed by immunohistochemical methods.

RESULTSc-myb oncoprotein was observed on the nucleus of cumulus cell and head of sperm. c-myb ASODNs inhibited the rate of fertilization in vitro in a dose-dependent way. The fertilization rates of the control group, low (5 micromol/L), medium (10 micromol/L), high (20 micromol/L) concentration c-myb ASODNs groups and nonsense tat oligodeoxynucleotides (20 micromol/L) group were 34.97%, 30.89%, 20.14%, 16.68%, 34.47%, respectively. All of GABA, Progesterone and dbcAMP inversed the c-myb ASODNs inhibition effects on fertilization rate, but neither of them showed significant effect on the percentages of immunohistochemical stain of Myb on sperm and cumulus cells. By contrast, Verapamil inhibited the fertilization rate. Co-treated with c-myb ASODNs, Verapamil showed synergic inhibiting effects on the fertilization with c-myb ASODNs. Verapamil also inhibited the expression of Myb on head of sperm. The fertilization rates of the control group, medium (10 micromol/L) concentration c-myb ASODNs group, GABA group, P4 group, Verapamil group, dbcAMP group were 34.81%, 22.96%, 40.83%, 39.12%, 7.46%, 40.61%, respectively.

CONCLUSIONc-myb ASODNs is closely correlated with fertilization. Verapamil can inhibit fertilization in vitro through regulating Myb expression of sperm, while GABA, dbcAMP and Verapamil may affect the process of fertilization through the way other than Myb expression.
