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.

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.

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 optimize the technology conditions of ultrasonic-enzyme-assisted extraction for sanguinarine from Zanthoxylum nitidum.Methods Extraction rate of sanguinarine determined by HPLC was served as an index.The applicability of the extraction solvent added with acid and enzymatic hydrolysis pretreatment to the ultrasonic-enzyme-assisted extraction of Zanthoxylum nitidum was investigated.Ultrasonic power,extraction frequency and solvent volume were optimized by orthogonal experiment.Finally,ultrasonic extraction time was optimized in dynamic process.Results The optimal process was as follows:Zanthoxylum nitidum powder was extracted 3 times by ultrasonic-wave (250 W) with 40％ ethanol (0.2％hydrochloride) as solvent (extracted for 15 rmin with 6-fold solvent at the first time,then extracted for 12 min with 3-fold solvent at the second and the third time,respectively).The extraction rate of sanguinarine was 88.6％.Conclusion The process is economic,efficient,energy-and time-saving,and provides experimental basis for industrial production of sanguinarine.

Background The alteration of dominance eye is associated with visual quality in patients with age-related cataract or after cataract-surgery.However,the study on the relationship of dominance eye shift with vision following cataract-surgery is lack.Objective This study was to observe the influence of age-related cataract and cataract surgery on ocular dominance in the elderly.Methods A serial cases-observational study was designed.Eighty-seven patients with age-related cataract were collected from December 2011 to April 2012 in Affiliated Eye Hospital of Wenzhou Medical University,and phacoemulsification combined with intraocular lens (IOL) implantation was performed in all the patients.The patients were grouped into binocular vision difference (best corrected distance vision) ≥2 lines group (42 patients) and ≤ 1 line group (45 patients) on the standard logarithmic visual acuity chart.The frequency and shift of dominant eye were determined by card-hole method or thumb method before operation and 1 day,1 week,1 month and 3 months after operation.The difference in the frequencies of dominant eye between before and after operation was analyzed with MecNmar test.Results The median of best corrected distance vision (LogMAR) was 0.40 (0.00-1.40) in preoperation and 0.00 (-0.08-0.30) in postoperation,with significant difference between them (Z=-9.481,P =0.000).In the binocular vision difference ≥ 2 lines group,the dominant eyes were 24 in the right eyes and 18 in the left eyes.The milder cataractous eyes were identified as dominant eyes in 33 (78.57％) patients and heavier cataractous eyes were determined as dominant eyes in 9 (21.43％) patients before operation.However,the right eye was evidenced as dominant eye in 31 patients and the left eye was in 11 patients after operation.In the 42 patients,dominant eye shifted from the left eyes to the right eyes in 10 patients and from the right eyes to the left eyes in 3 patients,and 4 patients presented an unstable change binocularly.In 45 patients of the binocular vision difference ≤ 1 line group,the dominant eyes were the right eyes in 27 patients and the left eyes in 18 eyes in preoperation ; while after operation,dominant eye altered form the left eyes to the right eyes in 3 patients and form the right eyes to the left eyes in 1 patient,and unstable change occurred in 5 patients.There were no significant differences in the frequency of dominant eyes between before and after operation both the two groups (group A:P =0.092 ; group B:P =0.727).Conclusions Age-related cataract impact on eye dominance.Dominance eye may occur alteration binocularly following cataract surgery,which is one of causes of visual discomfort.
