Age-related macular degeneration( AMD) is one of the major reasons of blindness among the elderly in the developed countries. As AMD patients are increasing year by year, AMD has become one of the important topics of ophthalmic research to prevent blindness. Its pathogenesis is not fully understood, but many studies have shown that vascular endothelial growth factor ( VEGF ) plays an important role in the pathogenesis. With the development and application of anti - VEGF drugs, there are a variety of drugs applied to the disease. This article introduces conbercept for the treatment of AMD.

ObjectiveTo survey the social support to students in university.Methods400 college students of grade 2004 from 4 different colleges in Ningbo were tested with the Social Support Rating Scale(SSRS).Results and ConclusionThere were no significant differences among students from Ningbo and students from the other regions.Students from different level colleges had different scores in utilization of support,students from the third level college had the highest scores while students from the forth level had the lowest scores.College students from countries scored higher than students from cities in subjective support,but there were no significant differences in objective support and the utilization of support.Female students had higher scores in subjective support and utilization of support than males while had no significant differences in objective support.Students with different majors had no significant differences in objective support and utilization of support,while concerning subjective support,students from management departments had the highest scores,students from arts departments had the lowest scores.In case of emergency,college students mainly received economic support and mental support from their families,friends and classmates while received less support from various organizations both of colleges and society.

ObjectiveTo investigate the relationship between family cohesion, family adaptability and perceived social support.Methods400 college students of grade 2004 from 4 different colleges of Ningbo were tested with the FACESⅡ-CV and perceived social support scale. Results and ConclusionFamily cohesion and adaptability significantly positively correlated with perceived family support and social support. There was no significant correlation between perceived family support and dissatisfaction with family cohesion, while perceived family support significantly negatively correlated with family adaptability. In family adaptability, dissatisfaction with family cohesion and family adaptability, there were significant differences among students from different level colleges. In perceived family support, there were no significant differences among students from different college. In family cohesion, female students scored higher than male, but showed no significant differences in family adaptability. In perceived family support and social support, female students had higher scores than male were. In family cohesion and perceived family support, fathers' education background but not mothers' had significant main effect. In family cohesion, family adaptability and perceived family and social support, there were no significant differences between students from cities or countries.

OBJECTIVETo investigate the mechanism of Yanshu Injection (YI) for overcoming multidrug resistance in breast carcinoma MCF-7 cells.

METHODSHuman breast carcinoma MCF-7 cells and doxorubicin-resistant MCF-7/DOX cells were treated with YI. Its inhibition on the cell proliferation was detected by MTT assay. The fluorescence intensity of doxorubicin was detected by flow cytometry. The expression of apoptosis related protein and P-glycoprotein were examined by immunoblotting after treated by YI.

RESULTSThe inhibitory action of YI on MCF-7/DOX cells was similar to that of MCF-7 cells, indicating no cross resistance (P > 0.05). 1/16 YI could obviously induce the apoptosis of MCF-7 cells and DOX cells. 1/256 YI +5 nmol/L doxorubicin and 1/128 YI +5 nmol/L doxorubicin could reduce the survival rate of MCF-7/ DOX resistant cells from 86.8% to 74.6% (P < 0.05) and 71.6% (P < 0.01) respectively, showing obvious synergistic effect. Besides, the accumulation of doxorubicin was increased after treated by YI in the MCF-7/ DOX cells. Results of immunoblotting indicated that reduction of P-glycoprotein expression was detected in MCF-7/DOX cells after exposure to YI.

CONCLUSIONYI could overcome the multidrug resistance in breast carcinoma MCF-7 cells possibly through reducing the expression of P-glycoprotein.

Objective To study the clinical pathological features of mesenteric and omental inflammatory myofibroblastic tumor (IMT) in children.Method Clinical features,laboratory result,pathological evidence for diagnosis and treatment of 5 cases with mesenteric and omental IMT were analyzed and evaluated.Results Intra-abdominal mass was most frequently found in childhood mesenteric and omental IMT.Gastrointestinal obstruction was showed in 2 cases.Anemia,leucocytosis,thrombocytosis,polyclonal-hyperglobulinemia appeared in 5 cases.The histological pattern showed:4 cases were myxoid pattern IMT,1 case was compact spindle cells pattern IMT.Immunohistochemistry showed:the spindle cells were expressed vimentin,smooth muscle action(SMA) and desmin.Partial spindle cells were anaplastic lymphoma kinase(ALK) and cytokeratin(CK) positive,while S-100 protein,CD34 were negative.Complete surgical excision was performed on 5 cases.Follow-up studies ranged from 5 months to 3 years,and no patient developed recurrence.Conclusions Childhood mesenteric and omental IMT is a rare interstitial tumor.The diagnosis should be based on pathological and immunohistochemistry examinations.Most cases are benign,and complete surgical excision can avoid local recurrence.

ObjectiveTo investigate the mental health of freshmen of university.MethodsSymptom Checklist 90 (SCL-90) was used to self evaluate 7763 freshmen of university in Ningbo.Results and ConclusionThe overall level of the mental health of this group was higher than that of the Chinese module, and the prevalence of psychological symptoms was 13.2%. The average level of mental health of female were inferior to male. The difference between the students from cities or towns and from the countryside were distinct. Students who were satisfied with their majority get noticeably higher average score than the ones who were not satisfied.

Objective To investigate the expression and significance of transforming growth factor beta receptors (TGF?RⅠ, TGF?RⅡ) in basal cell carcinoma and squamous cell carcinoma. Methods The expression of TGF?RⅠand TGF?RⅡwere assessed by quantitative real-time PCR and streptavidin -peroxidase (SP) immunohistochemical techniques in specimens of basal cell carcinoma, squamous cell carcinoma and normal control skin. Results Eighteen patients with basal cell carcinoma and twenty-four with squamous cell carcinoma were enrolled in the study. The expression levels of TGF?RⅠand RⅡmRNA were significantly down-regulated in basal cell carcinoma and squamous cell carcinoma in comparison with those in control skin specimens (P
