The eye neoplasm and the orbital diseases are a class of serious illness which will cause visual function damage and even life threatening.At present,the etiology and pathogenesis of the most eye neoplasm and orbital diseases are still not clear,which has an adverse effect on the treatment.The medical experimental animal models are the ideal model to simulate human diseases.At the same time,the establishment of related animal models with the eye neoplasm and the orbital diseases is a helpful aid in getting to know the etiology and pathogenesis,providing a basis for studying the etiology and pathogenesis of these diseases.Some progress has been achieved some progress in recent years,however,compared to other diseases,the related animal models of these are still few.The progress in the common experimental animal models of the eye neoplasm and the orbital diseases,the animal models of the thyroid-associated ophthalmopathy (TAO),the orbital adenoid cystic carcinoma,the retinoblastoma (RB),the uveal melanoma,and the idiopathic orbital inflammatory pseudotumor were reviewed in this article.

Objective To assess the effects of tibolone treatment on the hemodynamic changes of the ophthalmic artery(OA) and internal carotid artery(ICA) as sonographic markers of atherosclerosis in menopausal women.Methods A total of 30 menopausal women were treated with 2.5mg of tibolone(Livial) daily as treatment group.At the same time,30 women with natural menopause who were not given any treatment served as control group.Noninvasive measurements of the resistance index(RI) and peak systolic blood flow velocity of ICA and OA were made with ultrasound before the treatment and at 3rd,6th,9th and 12th month of treatment,respectively.Results RI of ICA and OA decreased significantly after tibolone treatment(P

Objective To study the relationship between the MRI features of acute cerebral infarction (ACI) and developing vascular dementia (VD). Methods The patients who had ACI history more than 6 months were divided into vascular dementia group and no vascular dementia group by MMSE and CDR evaluations. The MRI data of acute stoke of the two groups were reviewed and analyzed retrospectively. Results In VD group the happenings of infarction at subcortex of lobus frontalis, subcortex of lobus temporalis, anterior capsula interna, knee of capsula interna, nucleus caudatus and thalamus were more than those in no vascular dementia group (P

Objective 　To search the relative factors of cerebral damage, rebleeding, delayed cerebral ischaemia(DCI) and hydrocephalus after subarachnoid haemorrhage (SAH) by CT scans and clinical findings in acute phase. Methods　To analyse the relationship between cerebral damage after SAH and clinical findings: CT scans resulte, age, sex, blood pressure, hyponatraemia, therapeutic methods. Results　Cerebral damage were related to the pattern of distritution of SAH on brain CT and hyponatraemia. The high attack rate of rebleeding and DCI is related to presence of blood in the surface of brain, collection of blood in the ventricle, saccula aneurysms or cerebral arteriovenous malformation (AVM) (P＜0.01). Conclusions　To forecast of cerebral damage after SAH by study of CT scans showing and clinical findings have clincal significance. According to these findings, we may take some therapeutics to prevent the cerebral damage after SAH.

OBJECTIVE:To provide reference for drug use labeling for pregnant and lactating women. METHODS:The drug package inserts were collected from Linxi Hospital of Kailuan General Hospital during Jul. 2013-Dec. 2015. The information about drug use labeling for pregnant and lactating women was analyzed statistically. RESULTS:Among 762 drug package inserts,pack-age inserts which were not labeled with or labeled with indefinite drug use information for pregnant and lactating women accounted for 31.89% and 52.76% respectively. Among package inserts of 361 domestic chemical drugs and biological products,339 Chinese patent medicine and 62 imported drug,package inserts which were not labeled or labeled with indefinite drug use information for pregnant and lactating women accounted for 22.99% and 25.21%,44.54% and 88.50%,14.52% and 17.74%,respectively. CON-CLUSIONS:Except for poor drug use labeling for pregnant and lactating women in package inserts package,there still are other problems,such as items listed dispersedly,presentation content not consistent. Compared with imported drugs,the missing informa-tion for pregnant and lactating women are obvious in drug package inserts of domestic chemical drugs and biological products,and severe in those of Chinese patent medicine. It is recommended that drug manufacturers should strengthen drug tracing and monitor-ing after listed,and update and revise related content of package inserts timely;drug administration department should strengthen drug package inserts supervision,and unify and standardize labeled content management of drug use.

CONCLUSION: Zisheng Qingyang Table can obviously improve TCM syndromes, The effects especially exist in relieving the main symptoms as follows: dizziness, headache, chest distention, palpitation. The action of Zisheng Qingyang Tablet and captopril for lowering BP is alike.

Purpose Cortex is one of the frequently involved sites of multiple sclerosis (MS),and the cortex and corpus callosum lesions of MS are gradually concerned.The study aims to observe the changes of cerebral cortex and corpus callosum of MS in experimental autoimmune encephalomyelitis (EAE) model by using 7.0T MRI diffusion tensor imaging (DTI).Materials and Methods Twenty female C57BL/6 mice of 6-8 week old were enrolled in the study,10 of which were induced by MOG35-55 to make EAE models and the rest 10 of which were taken as control group.On the 20 days after model establishment,the head T2WI and DTI were performed on both control and EAE mice.DTI quantitative indicators such as fractional anisotropy (FA),mean diffusivity (MD),axial dispersion coefficient λ//,and radial dispersion coefficient λ ⊥ in region of interest including bilateral prefrontal cortex,bilateral cingulate cortex and corpus callosum were compared between the two groups.Results No obvious lesions were observed on the T2WI in both control and EAE groups.In the experimental group,the FA mapping suggested the integrity of the left side of the corpus callosum was destroyed.The FA,MD,λ// λ ⊥ of bilateral prefrontal cortex and corpus callosum showed significant difference between experimental group and control group (P＜0.05);the increase of λ ⊥ in bilateral cingulate was significantly different from that in the control group.Meanwhile,HE staining in the experimental group showed that inflammatory cells gathered around the cortical and subcortical vessels.The LFB staining in experimental group showed a bit paler than that in the control group,and the corpus callosum showed patchy demyelination.Conclusion The technique of 7.0T MRI DTI sequence can detect cortex and corpus callosum lesions which cannot be found by conventional MRI,so that it provides radiological evidence for the study of MS with cortex and corpus callosum lesions.

Background Idiopathic orbital inflammatory pseudotumor (IOIP) is a common orbital disease, but its etiology is still unclear,so the effect of glucocorticoid treatment is unsatisfied.Objective This study was to investigate the effects of dexamethasone on orbital fibroblasts from IOIP patients and explore the action machanism.Methods Six pieces of IOIP tissues from 6 IOIP patients and 3 pieces of normal orbital connective tissues from lacrimal gland prolapse patients were obtained during the surgery in Beijing Tongren Hospital from November 2011 to January 2012.The orbital fibroblasts were cultured using explant culture method.The morphology of the cells were observed under the optical microscope,and biomarks of the cells were detected by immunochemistry.The growth and proliferation of the cells were assayed using WST-8.The expression of ICAM-1 in the cells in both the control group and the IOIP group was detected by immunochemistry.The fibroblasts were incubated in 96-well plates, and different concentrations of dexamethasone (0,1 × 10-3 , 1 × 10-4 , 1 × 10-5 and 1 × 10-6 mol/L) were respectively added into the medium for 24,48 and 72 hours,and then the proliferation of the cells was detected by WST-8 assay.The contents of ICAM-1 in different concentrations of dexamethasone groups were assayed by ELISA.Results The characteristics of the cells were similar between the control group and the IOIP group with the spindle shape and long protructions.The cells showed the positive response for vimentin and absent response for desmin, S-100, cytokeratin (CK).Compared with the control group,the growth speed of fibroblasts was fast in the IOIP group.The proliferative values of the cells (absorbancy) were gradually reduced with the increase of dexamethasone concentrations (F ion =36.27,P=0.00) and the lapse of acting time (Ftime =3.69 ,P=0.00).In cultured cells without dexamethasone for 24,48 and 72 hours,the mean expression levels of ICAM-1 were 0.298±0.008,0.312±0.003 and 0.319±0.011, showing a gradually increasing trend.However,the expression of ICAM-1 was gradually reduced with the increases of concentrations and the lapse of acting time of dexamethasone (Fconcentration =75.17,P=0.00;Ftime =3.11,P=0.00).Conclusions Occurrence and development of IOIP is probably associated with the over-expression of ICAM-1 in orbital fibroblasts.Dexamethasone plays anti-inflammation and treating effects on IOIP by down-regulating the expression of ICAM-1 and inhibiting the proliferation of orbital fibroblasts.

BACKGROUND: Studies have shown that adipose-derived stem cells have pluripotent differentiation potential, but only 30%-40% of cells can differentiate into mature adipocytes with low adipogenic differentiation potential. Therefore, how to improve the adipogenic differentiation ability of adipose-derived stem cells is a key problem to be solved in the process of soft tissue regeneration. OBJECTIVE: To observe the relationship between the surface marker CD54 of rabbit adipose-derived stem cells and their adipogenic capacity, and to explore the adipogenic differentiation of CD54+/CD54- adipose-derived stem cells underthe same induction. METHODS: We successfully isolated and cultured the adipose-derived stem cells from inguinal subcutaneous fat pads (3 ml) of New Zealand white rabbits, aged 8-12 weeks, which were induced into multi-differentiation and used to detectsurface markers. We sorted the passage 3 adipose-derived stem cells by immunomagnetic beads and divided into two categories including CD54+ and CD54- adipose-derived stem cells. After 14 days of adipogenic induction, the cells in the two groups were subjected to oil red O staining and were compared by detecting the density of mature adipocytes and lipid droplet contenT.RESULTS AND CONCLUSION: The cultured adipose-derived stem cells possessed the characteristics of mesenchymal stem cells that could differentiate into mature adipocytes, osteoblasts and chondrocytes, with CD29, CD44, CD49d, CD54, CD73, CD90 and CD105 positive expression while CD31, CD34 and CD45 negative expression. Fourteen days after adipogenic induction, the density of mature adipocytes and the intracellular lipid droplet content in the CD54+ group were significantly higher than those in the CD54- group (P < 0.05). We also found that the mRNA expressions of PPARγ,ADD1, C/EBPα related to adipogenic differentiation in the CD54+ group were significantly higher than those in the CD54- group (P < 0.05). Taken together, CD54+ adipose-derived stem cells have excellent adipogenic differentiation capacity.

Objective To investigate the effect mechanism of sanguinarine on the proliferation,apoptosis,invasion and migration abilities of cervical cancer cells.Methods MTT,flow cytometer,cell scratch test and Transwell chamber assay were respectively used to detect the cellular proliferation,apoptosis,migration and invasion abilities after sanguinarine action.The expression levels of E-Cadherin,PTEN,β-catenin and MMP2 protein of cervical cancer cells after sanguinarine action were detected by Western blot.Results 0.6,0.8 μmol/L sanguinarine had the inhibitory effect on the proliferation of cervical cancer cells.After 0.8μmol/L sanguinarine action for 48 h,cervical cancer HeLa and Siha cells apoptosis rate were up to (45.68± 2.26)％ and(31.89 ± 3.80)％ respectively.0.8 μmol/L sanguinarine action for 3 h,cervical cancer cells HeLa and Siha adhesion rates were only (67.45 ± 2.13)％and(73.59± 2.61)％.0.8 mol/L sanguinarine action for 16 h,the invasion numbers of cervical cancer Hela and Siha cell were (39.64 ±1.98) and (43.87 ± 2.83) respectively.The expression amount of E-Cadherin and PTEN in cervical cancer cells after sanguinarine action was increased,while the expression amount of E-Cadherin and PTEN was weakened.Conclusion Sanguinarine has the proliferation inhibiting and apoptosis promoting effect on cervical cancer cells,its mechanism may be related to adhesion protein E-Cadherin,β-catenin and PTEN,MMP2.
