Objective; To elucidate the mechanism of the role of ER-a in fat metabolism by regulating the expression of ER-a in SD rats marrow mesenchymal stem cells during differentiating into adipocytes in vitro. Methods ;SD rats marrow mesenchymal stem cells were separated and cultivated. The ER-a was transfected into the rBMSCs in group one. Tamoxifen Citrate was used to restrain the expression of ER-a in group two, the group without any treatment was used as control. Western blot was used to identify the difference of ER-a expression among different groups and Oil-Red-0 staining was employed to identify the adipocytes in vitro. Results; There was significant difference between the number of lipids and different groups (P <0. 01) ,the number of lipid droplet changed concomitantly with ER-a: Low-expression ER-a group > Control group > High-expression ER-a group. Conclusion; ER-a in SD rats marrow mesenchymal stem cells may restrain the adipocyte differentiation.

Objective To compare two kinds of strategies of preimplantation genetic diagnosis (PGD) to evaluate embryos for reciprocal and robertsonian translocation carriers. Methods A total of 152 PGD cycles for chromosomal translocation were performed from April 2012 to June 2014 , including 60 aCGH-PGD cycles using blastomere biopsy and fresh embryo transfer, and 92 SNP-PGD cycles using blastocyst biopsy and thawed embryo transfer. The diagnosis results and clinical outcome with these two kinds of strategies were compared. Results No significant difference was found in the cycles of no embryo transfer between SNP-PGD and aCGH-PGD. The normal rate in SNP-PGD was 33.8%, which was significant higher than that of aCGH-PGD. The clinical pregnancy rate per embryo transfer in SNP-PGD was higher than that in aCGH-PGD, but the misscarrage rate and embryo damage rate were lower than those in aCGH-PGD. Conclusions The PGD strategy of applying blastocyst biopsy, SNP array, embryo cryopreservation and thawed ET leads to a better clinical outcome. It may be a promising choice for future PGD treatment for carriers with chromosomal translocation.

Objective To probe into the clinical value of left atrial(LA) volme tracking method (LAVT) on the assessment of left atrial function in patients with hypertension. Methods Thirty-one patients with hypertension and 31 control subjects were involved. Images of apical two-chamber and four-chamber views were obtained by two-dimensional echocardiography. LA maximal volume (LAVmax), LA minimal volume (LAVmin), LA presystolic volume (LAVpre), systolic LA filling rate (dv/dtS), early diastolic LA emptying rate (dv/dtE) and late diastolic LA emptying rate (dv/dtA) were derived using LAVT. LA passive emptying volume(LAVp), LA passive emptying fraction(LAVpEF), LA active emptying volume(LAVa), LA active emptying fraction (LAVaEF), LA total emptying volume (LAVt), LA total emptying fraction(LAVtEF) were calculated. All volume measurements were corrected to body surface area (LAVI). Results There were significant differences in the LAVImax, LAVImin, LAVIpre, LAVpEF, LAVIa, LAVIt,dv/dtS, dv/dtA between hypertensive patients and control subjects(P <0.05~0.001), but no significant differences were found in the LAVp, LAVaEF, LAVtEF,dv/dtE between the two groups. The LAVImax has shown significant positive correlation with LAVIp, LAVIa and LAVIt(r = 0.588~0.812, P <0.001). LAVaEF has shown positive correlation with the LAVtEF(r = 0.833, P<0.001), whereas LAVpEF has not(r = 0.420, P <0.01). There was a significant positive correlation with LAVImax and LAVIpre(r = 0.908, P <0.001), LAVIpre and LAVIa(r = 0.689, P <0.001) ,dv/dtE and LAVIp(r = 0.690, P <0.001),dv/dtA and LAVIa(r = 0.600, P <0.001). Conclusions In hypertensive patients,left atrial reservoir function and booster pump function increase, while left atrial conduit function decreases. LAVT has a potential ability to evaluate left atrial function.
