Development of a duplex fluorescence RT-PCR assay for identifying SRBⅠgene knockout mice / 天津医药

Objective To develop a duplex fluorescence RT-PCR assay for detection of scavenger receptor class B, typeⅠ(SRBⅠ) knockout mice. Methods Primers and probes were designed according to knockout region of SRBⅠgene and related substituted sequence. DNA samples were extracted from tails of mice and performed amplification using real-time PCR. SRBⅠgenotypes of mice were analyzed according to amplification curves of FAM and CY5 channels. Finally, the sensitivity of the method was detected and the accuracy was verified by the direct sequencing. Results The homozygous SRBⅠwild genotype showed an amplification curve only in FAM channel. When the homozygous SRBⅠknockout genotype was present, the typical S amplification curve appeared only in the CY5 channel. Heterozygous genotype showed two typical S amplification curves in both FAM and CY5 channels, respectively. The results showed that the sensitivity reached 4×101 copies/μL, and there was complete concordance between this method and direct DNA sequencing. Conclusion The new method is simple, rapid and accurate, which is suitable for genotyping SRBⅠknockout mice.

Multislice Spiral CT Features of Renal Chromophobe Carcinoma / 中国医学影像学杂志

Purpose To explore the multislice spiral CT (MSCT) features of renal chromophobe carcinoma, and to improve the understanding and diagnosis of the disease. Materials and Methods MSCT features of 17 patients with renal chromophobe carcinoma confirmed by surgical pathology were retrospectively analyzed, plain MSCT and multi-phase dynamic contrast-enhanced scan were applied to these patients. Results Single substantive round or oval-shaped soft tissue mass was demonstrated in 17 cases. The lesions were all uniform density on plain MSCT, and mild to moderate homogeneous enhancement in 11 cases on enhanced MSCT, including 9 cases with significant enhancement above the renal medulla and below the renal cortex, and 2 cases with similar enhancement to renal medulla in corticomedullary phase. On nephrographic phase the lesion showed significant lower density than renal medulla. Heterogeneous enhancement presented in 6 cased, including 1 case with small necrosis and 1 case with stellate scar lesion in low-density. Conclusion Renal chromophobe carcinoma demonstrates a round solid mass of uniform density on plain MSCT, and mild to moderate homogeneous and heterogeneous, which can provide the reference value for preoperative diagnosis.

Estrogen increases apolipoprotein M through estrogen receptor / 中华内分泌代谢杂志

Objective To explore the effects of estrogen on apolipoprotein M ( apoM ).Methods ApoM mRNA was assayed in HepG2 cells by RT-PCR after incubation of estrogen with or without estrogen receptor antagonist at different concentrations and durations.SD female rats were divided into five groups:OVX group,Sham group,OVX+ EB group,normal group and normal + EB group.From a week of being operated,the rats were injected subcutaneously estradiol beuzoate or vehicle.After 12-hrs fasting,serum levels of triglycerides (TG),LDL-cholesterol,HDL-cholesterol,total cholesterol ( TC ) at months 1,2 and 3 after operation were measured.The expression of apoM in rats was detected by using real time RT-PCR and Western blot.Results Estrogen increased mRNA levels of apoM and apoAI in the HepG2 cells with a dose- and time-dependent manner,which could be abolished by addition of estrogen receptor antagonist.Serum apoM,TG,TC,HDL and LDL levels were significantly increased in the ovariectomized or normal rats which received estrogen treatment than those in OVX or normal group rats at month 1 after treatments.Conclusions Estrogen upregulates apoM expression via its receptor.
