AlM: To analyze, summarize and describe ophthalmic imaging features of posterior scleritis.
METHODS: Clinical data of 16 patients ( 21 eyes ) with posterior scleritis diagnosed in our hospital from October 2008 to June 2013 were retrospectively analyzed. The results of type-B ultrasonic, fundus chromophotograph, fundus fluorescein angiography, CT were recorded for comprehensive evaluation and analysis of ophthalmic imaging features of posterior scleritis.
RESULTS: All patients underwent type-B ultrasonic examination and manifested as diffuse and nodular types. The diffuse type showed diffusely thickened sclera and a dark hypoechoic area that connected with the optic nerve to form a typical “T”-shaped sign. The nodular type showed scleral echogenic nodules and relatively regular internal structure. FFA showed that relatively weak mottled fluorescences were visible in the arterial early phase and strong multiple needle-like fluorescences were visible in the arteriovenous phase, which were then progressively larger and fused; fluorescein was leaked to the subretinal tissue in the late phase;varying degrees of strong fluorescences with less clear or unclear boundaries were visible in the optic disk. CT results showed thickened eyeball wall.
CONCLUSlON: Posterior scleritis is common in young female patients, whose ophthalmic imaging features are varied and more specific in type-B ultrasonic. Selection of rational ophthalmic imaging examination method, combined with clinical manifestations, can accurately diagnose posterior scleritis and avoid the incidence of missed and delayed diagnosis.

Objective To establish a human colon cancer multi-drug resistant cell line LS174T/5-fluorouracil(5-Fu) and to explore its biological characteristics. Methods A resistant human colon cancer line LS174T/5-Fu was established by stepwise increasing concentrations of fluorouracil selection from the parental cell line LS174T.Drug sensitivity was detected by MTT assay,and the changes of biological characteristics were determined by light microscopy,cell counting,flow cytometry and RT-PCR. Results LS174T/5-Fu cell line was developed after 6 months with stable resistance to 5-Fu and a resistance index of 40.24.The cells exhibited cross-resistance to cisplatin,etoposide,doxifluridine and hydeoxycamptothecin.LS174T/5-Fu cells grew more slowly than LS174T cells,which was longer than LS174T cell line.Cell cycle distribution of LS174T/5-Fu cells was changed compared with parental cells.The percentage of cells in G_(1) and S phase was increased,while in G_(2) phase was decreased.The level of MRP mRNA expression was increased according to the concentration of 5-Fu in resistant cell lines. Conclusion LS174T/5-Fu cells is a reliable multi-drug resistant cell subline of human colon cancer.The successful establishment of this cell subline has laid a solid foundation for further study of the multi-drug resistant mechanism of human colon cancer induced by 5-fluorouracil.

Results The body weight of group B was about 60% of group A,and the average food intake was significantly declined(P

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

ObjectiveTo investigate the correlation between any two of Capsule Endoscopy ScroringIndex (Lewis score),simplified Crohn Disease Activity Index (CDAI) and C-reactive protein (CRP) in small bowel Crohn disease (CD).MethodsA total of 58 consecutive patients with known small bowel CD were enrolled. We evaluated disease activity with Lewis score and simplified CDAI. Correlations among CRP,simplified CDAI and Lewis score were calculated with Spearman's rank order correlation coefficient.The optimal CRP cut-off value was calculated using the ROC curve.ResultsThe Lewis score showed inactive,mild and moderate-severe patients were 13,21 and 24,respectively.CRP of moderate-severe group was significantly higher than that in mild and inactive groups ( P ＜ 0.05 ).The optimal CRP cut-off value that differentiated patients with moderate to severe disease from the others was 13.50 mg/L with sensitivity of 87.5％ and specificity of 82.4％.The area under the ROC curve to analyze the cut-off was 0.849.Lewis score was moderately correlated with CRP (r =0.58,P ＜ 0.01 ),and weakly correlated with the simplified CDAI (r =0.40,P ＜ 0.01 ).ConclusionSerum CRP and the simplified CDAI cannot replace Lewis score for capsule endoscopy in the assessment of disease activity in small bowel CD.However,CRP may be considered as an inflammatory marker for evaluating the moderate to severe capsule endoscopic activity.

Abstract?AlM:To analyze of the clinical features of acute retinal pigment epitheltis ( ARPE) .?METHODS: The clinical data of 36 ARPE patients ( 40 eyes) attending this center from January 2008 to January 2014 were reviewed retrospectively. Of them, 21 patients (58.3%) were male (male :female=1:0. 71). The mean age was 40. 92±7. 13 years old (range:17~60y). The mean best-corrected visual acuity (BCVA) was 0. 50±0. 26 with a range of 0. 3 ~ 1. 0. Thirty-two patients were unilateral cases. All the patients were examined for BCVA, funds photography, fluorescein fundus angiography ( FFA ) , optical coherence tomography ( OCT) . FFA was shown as three types: type ▏ to multiple black light or grape variety fluorescent spot; Type II for l lesions visible fluorescence leakage; Type Ⅲ lesions with choroid neovascularization ( CNV ) . OCT was the following three forms: multiple RPE lesions layer reflection intermittent, proliferation ( type ▏); pigment epithelial detachment with limitations neural epithelium ( typeII);types l and ll with CNV ( type Ⅲ) .?RESULTS: Ocular fundus showed that the lesions were multiple dark-gray spots with a dark circumscribed area at the macular or nearby in all 40 eyes. FFA showed:21 eyes were type ▏, 17 eyes were type II and 2 eyes were typeⅢ, BCVA between type ▏ and type II was statistically significant (P<0. 05), the same was between type 芋. BCVA between different cases in the same type and between type II, Ⅲ, was no statistical difference ( P>0. 05). OCT showed 21 eyes wwere type ▏, 17 eyes were type II and type Ⅲ 2 eyes. BCVA average between type▏ andIIwas statistically significant (P<0. 05). The mean BCVA was no statistically significant difference between type II and Ⅲ patients (P>0. 05).?CONCLUSlON:ARPE fundus demonstrated the multiple dark gray discrete lesions, the degree of visual impairment related with the presence of pigment epithelial barrier and lesion location. OCT and FFA characterized three types. FFA is shown asblack light orgrape variety fluorescent spot, and is the basis of diagnosis. OCT can display the lesions organization form of each layer clearly. lt plays a more and more important role in the diagnosis and differential diagnosis of ARPE.

ObjectiveTo investigate the epidemiology of senile dementia in Shanghai.Methods15158 residents aged 65 or over were selected by stratified random cluster sampling from 3 districts in Shanghai. Two stages was carried to ascertain dementia: in the first stage, Mini Mental State Examination (MMSE) and Activity of Daily Living Scale (ADL) were used as screening tools; in the second stage, DSM-Ⅳ criteria for dementia was applied to diagnosis.ResultsScreening positive rate of MMSE and ADL are both 9.9%. 1271 cases of elderly with dementia were identified. The crude and age-standardized prevalence in residents aged 65 or over was 8.1% and 6.1%. The female, older age, lower education and worse marriage seemed to be more susceptible to senile dementia(P<0.01).ConclusionSenile dementia has become one of major diseases harmful to elderly's health.

ObjectiveTo evaluate probability and severity of behavioral and psychological symptoms in dementia (BPSD) in elderly with dementia in Shanghai.MethodsOn the basis surveyed before, total 1271 elderly with dementia were investigated with the international neuropsychiatric inventory (NPI) to evaluate BPSD.ResultsThe proportion of elderly with dementia that had BPSD was 50.95% , it was 32.17% for clinical significant disturbance (CSD). The symptoms had greatest impact on the caregivers were paranoia (2.32±1.48), followed by abnormal motor behavior (2.30±1.31) and hallucinations (2.16±1.25). The severity rating included mild 620 cases, moderate 238 cases, and severe 406 cases.ConclusionThe incidence rate of BPSD in elderly with dementia was high. The standard of severity grading should be selected with purposes.

ObjectiveTo analyze burden and tolerance of caregivers of elders with dementia in Shanghai.MethodsOn the basis of surveyed before, total 1271 caregivers of elders with dementia were investigated with the questionnaire that concerned the demographic characteristics, influence on body, psychology, life and tolerance.ResultsNearly 60% of the caregivers felt stress, nearly 40% of the caregivers thought that mental pressure had a negative impact on their health as a result of caring patients. Most of the caregivers responded with tolerance to non-adaptive behavior.ConclusionDementia caregivers are old, the burden is heavy. It is necessary to establish a social support system for elderly with dementia as soon as possible.
