Objective To analyze retrospectively MRI features of ectopic pregnancy correlated with pathology.Methods Eleven patients with pathologically proved ectopic pregnancy were enrolled in this study:one with cornual pregnancy,six with interstitial pregnancy,two with tubal isthmus pregnancy,one with ampullary pregnancy,and one with primary abdominal pregnancy.Six under-went MRI plain scan,and five underwent MRI both plain scan and enhancement scan.We evaluated the location,the size,the signal intensity of the gestational sac (GS),vessels around the GS,dilatation tubal,hematosalpinx and hemoperitoneum.Changes of the thickness of the endometrium,functional ovarian cysts and ovarian corpus luteum were also evaluated.Results Among these eleven patients,GSs were detected in ten patients.The locations of the GSs on MRI were corresponding with the results of surgical explora-tion.GS was not detected in only one patient with tubal pregnancy,but hematosalpinx and pelvic hematocele could be seen in MRI. Conclusion MRI is an effective modality for evaluating GS and its adjacent organs.The imaging features of GS and other indirect signs can be helpful to the diagnosis and differential diagnosis of ectopic pregnancy on MRI.

0.5.8 factors can explain the 80% of the whole variable. There were significant differences in the aspects of emotion,ADL/IADL,moving ability,participating and the total score(P

ObjectiveTo explore the factors influencing quality of life (QOL) in post-stroke patients.MethodsThe data of 76 first-stroke patients in three general hospitals at 1 month and 4 months after stroke were selected with Stroke Impact Scale and analyzed with multiple linear regression.ResultsThe influencing factors of patients' QOL at one months after stroke were education background, type of care, gender, pathological regions, marriage and complications. The education background was the most important influencing factor. The influencing factors of 4 months after stroke were rehabilitation nursing, marriage, social support and gender. Rehabilitation nursing was the most important influencing factor.ConclusionThe many factors influence QOL for post-stroke patients and are changed with time.

Vitamin D receptor (VDR) genotypes and bone mineral density (BMD) of 611 subjects in Shanghai were investigated. The results indicated that the frequency of Bb genotype in male is higher than that in female (26.9% vs 12.7%, P

Objective To explore pathological changes of optic nerve in experimental autoimmune encephalomyelitis(EAE).Methods Established the Wistar rat models of EAE by footpad injection of guinea pig spinal cord homogenates and CFA.Animals were executed 6 days after disease onset,and optic nerves,brains and spinal cords were removed for light(HE staining and LFB staining) and electron microscope pathological analysis.Results Various degrees of inflammation and demyelination of brains and spinal cords were found in the rats of EAE group.All the EAE rats had optic neuropathy mainly manifested as inflammation and demyelination under light microscope.Demyelination changes were more apparente than inflammation in optic nerves.Electron microscope observes decreased number of myelin sheaths and Oligodendrocytes(OLGs),OLGs karyopycnosis and the loosed myelin sheaths and their disassociation from axons were also found nearby.Conclusions Optic neuropathy is obvious in this rat model of EAE,mainly manifested as optic inflammation and demyelination.

Fifty-four cases of woman with lactation insufficiency were treated with acupuncture at acupoints Shaoze (SI 1), Danzhong (CV 17), Rugen (ST 18), Pishu (BL 20), Zusanli (ST 36) and Sanyinjiao (SP 6), and 42 cases got significant effect that the milk could fully meet baby's nutritional requirement, 9 cases got improvement, 3 cases discontinued the treatment.

OBJECTIVE To investigate the impact on semen quality of Ureaplasma urealyticum(Uu) and Chlamydia trachomatis(Ct) infections.METHODS Uu and Ct in semen were detected and the samples of semen were analyzed for 228 cases in infertiliry group and 132 cases in fertility group,The semen quantity,sperm density,survival rate,vitality,liquefacient duration,normal morphologic rate,deformity rate and death rate were compared.RESULTS Among 228 cases in infertility group,173 were positive in Uu and Ct(75.9%),obviously higher than that of fertile males(28.0%).Sperm density,vitality,survival rate and normal morphologic rate in the infertility group were remarkably lower than those of the fertility group(P0.05).CONCLUSIONS The genital infection of Uu and Ct has its impact on the multiple parameters of semen,and semen quality as a whole is decreasing.

BACKGROUND:It is vital to choose the appropriate carrier with low toxicity and high gene transfection efficiency in gene therapy, which is harmless to human body and environment. OBJECTIVE: To prepare superparamagnetic Fe3O4/SiO2-polyethyleneimine (PEI) composite particles. METHODS: Fe3O4 nanoparticles were prepared via an emulsion solvent evaporation method and superparamagnetic Fe3O4/SiO2 core shel microspheres were prepared successfuly subsequently via a modified stober method. The microspheres were further modified with PEI to obtain superparamagnetic Fe3O4/SiO2-PEI composite particles. The structures and properties of resultant composite particles microspheres were characterized by transmission electron microscopy, zeta potential and vibrating sample magnetometer. Superparamagnetic Fe3O4/SiO2-PEI composite particles were mixed with plasmid DNA at different mass ratios (29∶1, 39∶1, 49∶1, 59∶1, 68∶1, 78∶1, 88∶1). Thein vitro gene transfection ability was evaluated by Hela cels with the transfection of plasmid DNA encoded with green fluorescent protein and the transfection efficiency was determined by confocal fluorescence microscopy. RESULTS AND CONCLUSION: We successfuly synthesized the Fe3O4/SiO2-PEI composite particles with good dispersibility and even size distribution (about 100 nm). The surface charge was 21.07 mV, and the saturation magnetization was 28.05 emu/g that meant superparamagnetism. When the mass ratio was 59∶1, al the plasmid DNA was adherent to the Fe3O4/SiO2-PEI composite particles; when the mass ratio was > 59∶1, there were excessive Fe3O4/SiO2-PEI composite particles. Therefore, the mass ratio of 59:1 could lead to a better outcome for HeLa celltransfection. These results indicate that the Fe3O4/SiO2-PEI composite particles can dramaticaly improve the transfection efficiency of plasmid DNA compared with PEI.
