Objective To detect the pathological state of metabolic syndrome and the expression of microRNA-205 in women with endometrial cancer.Methods Thirty-eight cases of patients with endometrial cancer were collected including waist circumference,weight,blood pressure.Collected preoperative fasting blood,postoperative endometrial lesions and endometrium tissue adjacent to carcinoma paraffin section.Analyzed the metabolic syndrome in patients with pathological state indicators,extracted the total RNA of endometrium tissue and the level of microRNA-205 was detected.Results The prevalence of metabolic syndrome was 44.74% (17/38).The abnormal rate of high-density lipoprotein cholesterol,blood pressure,triglycerides,waist circumference,fasting blood sugar successively were 52.6% (20/38),36.8% (14/38),34.2% (13/38),34.2% (13/38) and 26.3% (10/38).The expression level of microRNA-205 in endometrial carcinoma was higher than that in normal endometrium tissues,there was significant difference (P < 0.01).Conclusions Metabolic syndrome is closely associated with the metabolic syndrome and its components.The expressions of microRNA-205 may participate in the occurrence and development of endometrial carcinoma,and it may be as an early screening of molecular markers.

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 detect the expression of nucleolin in cardiac hypertrophy rats induced by pressure overload.
METHODS:
A total of 40 SD rats with body weight 180 g and 220 g were recruited and randomly divided into 2 groups: a transverse aortic constriction (TAC) group and a sham surgery group. Cardiac hypertrophy model was employed by transverse aortic constriction surgery. Then 2 weeks and 4 weeks after the experiment, the heart mass index (HMI), left ventricle mass index (LVMI) were measured. β-MHC mRNA in the heart tissue was detected with RT-PCR. Nucleolin in the heart, brain and kidney was respectively detected with Western blot.
RESULTS:
Compared with the sham surgery group, HMI, LVMI in the TAC group increased significantly (P<0.01) 4 weeks after the surgery; the expression of β-MHC mRNA in the heart tissue increased (P<0.05) in the TAC group 4 weeks after the surgery; and the expression of nucleolin protein in the heart tissue of the TAC group was remarkably upregulated (P<0.05) 2 weeks after the surgery, with no change in the brain and kidney tissue between the 2 groups.
CONCLUSION
Expression of nucleolin protein has been upregulated in response to pressure overload, which may suggest that nucleolin plays a role in cardiac hypertrophy induced by pressure overload.
