The oligonucleotide primer having the 5’\|GCCGGTTATGGC AGCACGCTGACC\|3’ was synthesized,which encodes a main repetition motif of protein produced by the inaZ gene.PCR of the primer in the DNA of INA - and INA + bacteria and fungi was done.All of the DNA of INA - and INA + bacteria and fungi expressed bands,the results show that the primer did not work for distinguishing the INA - and INA + organisms and for identification of the ice nucleation activity of the INA organisms by the size and brightness of the PCR products.

Objective To study miRNA expression patterns in endometrial carcinoma(EC)combined with the Metabolic Syn-drome(MS)and non-combined with MS in order to explore the role of the microRNAs in EC combined with the MS.Methods Three fresh-frozen samples of endometrial carcinoma Combined with MS and 3 cases of non-Combined with MS and 1 case of nor - mal endometrium were collected.Total RNA was extracted from samples and miRNA microarray was used to evaluate the differenceof expression spectrum of miRNA.Results There were different expression of miRNA among the two groups of endometrium andnormal endometrium.There were 51 miRNA different expressions between EC combined with the MS and the normal endometri - um,and among them there are 15 upregulated miRNA and 36 downregulated miRNA.There were 9 miRNA different expressionsbetween EC non-combined with the MS and the normal endometrium ,and there are 3 upregulated miRNA and 6 downregulatedmiRNA among them.10 different miRNA were revealed between the two type of EC,and there are 4 upregulated miRNA and 6downregulated miRNA among them.Conclusion Different expressions of miRNA between EC Combined and non-Combined withMS may provide insights into their roles in the progression of EC .The study of miRNA contributes to elucidate the molecular mech - anismof endometrial carcinoma.

Objective To study absorption of shegan heji marker components in blood and their excretion in urine and feces of rats, after intragastric administration of shegan heji. Methods LC-MS/MS was used for determination of marker compounds. Rat metabolic cage technology was employed. Results Excretion of marker components were completed 24 hours after administration. Conclusion Ephedrine can be excreted from rats within 24 hours. The possibility of mutual transformation of flavonoids exists in the body. Taking shegan heji will not cause accumulation of ephedrine and flavonoids in the body.

Objective: To determine the pharmacokinetics of ephedrine hydrochloride in rats after intragastric administration of Shegan mixtures. Methods:Shegan mixtures (1. 0 ml/100 g) were administered to each rat by gavage. Blood samples were collected after the administration. Plasma concentration of ephedrine hydrochloride was determined by LC-MS/MS. The pharmacokinetic parame-ters of ephedrine hydrochloride were obtained using the pharmacokinetic software. Urine and fecal samples were collected in 24 hours after the administration using metabolic cage to determine the recovery of ephedrine hydrochloride. Results: The pharmacokinetic pa-rameters of ephedrine hydrochloride were as follows:Tmax of (1. 30 ± 0. 23)h,T1/2 of (21. 17 ± 1. 35)h, Cmax of (278. 86 ± 46. 41)ng ·ml-1,AUC0~∞ of (1221.98 ±412.64)ng·ml-1 and Vc/F of (1.70 ±0.15)L. Totally 85.66% ephedrine hydrochloride could be recovered from urine in 24 hours after the administration;however, it was not detected in the fecal samples. Conclusion: Most of e-phedrine hydrochloride is excreted through kidney in 24h,therefore, Shegan mixtures can't cause the accumulation of ephedrine hydro-chloride in rats.
