Using Kato's Self-abrasive Device, mass-screening for uterine cervical cancer has been carried out for 5, 983 married women at Chicheng country of a mountainous farm village and Shijiazhuang city in Hebei province, China, and the following result has obtained:
The women who diagnosed as class III and over were 42 persons (0.70%). Cancer cases which were confirmed by the biopsy were 10 (3 at Shijiazhuang city and 7 at Chicheng country); the occurrence rate of the cervical cancer was 0.17% and no false positive was observed. The mass -screening of the uterine cervical cancer has been carried out simultaneously by both way of the self-abrasive method and the scraper method for one third of persons who will take medical advice atboth districts. The result of comparative analysis for the quality of smear and the Papanicolaouclassification by the two method was;
1. As for the self-abrasive method, mixing with erythrocytes and overlapping of cells were few compared with the scraper method, and the diagnosis was more easily made in cytological examination.
2. The rate of coincidence by both methods were 78.85% in class I, 94.14% in class II, and 100.00% in class III-V.

BIOSIS previews is the well-known comprehensive index to life sciences and biomedical research. It is necessary for the researchers to know the index and use it to search the literature of microbiology . This article is the overview of BIOSIS previews including it's organization structure, features and using guide.

Objective To explore the clinical significance of the footprints and lateral X-rays in weight loading in evaluating the rehabilitation of talipes valgus in the children with cerebral palsy.Methods One hundred footprints of 56 children who were cerebral palsy with talipes valgus in the hospital-community-family-based rehabilitation mode were divided into light,middle and heavy types,and they were counted with two footprint-based approaches,and the two approaches were compared with chi-square criterion,and the dependability on consequence of the footprint and lateral X-rays in weight loading were analyzed.Results One hundred feet evaluated by the method of footprint were flatfeet radically,and the occurrence of flatfoot evaluated by three define lines were 11,57,32,respectively,and evaluated by footprint ratio were 6,7,87,respectively,but the degrees were different with two footprint-based approaches.There was a close correlation between two footprint-based approaches and lateral X-rays in weight loading.Conclusions Flat foot caused by talipes valgus can be evaluated by footprint in static state,while the development of bones of foot and the constitution of instep can be monitored on the lateral X-rays in weight loading.

Central serous chorioretinopathy (CSC) is characterized by serous detachment of the sensory retina as a consequence of the focal leakage of fluid from the choriocapillaries to subretinal space through a defect of the retinal pigment epithelium(RPE). The exact cause of CSC is not well unknown. Psychological stress is thought to contribute to CSC, but the physiologic mechanisms are unclear. It is hypothesized that psychological stress can induce CSC through the mechanism of the hypothalamic-pituitary-adrenal (HPA) system. Psychological stress can adversely affect HPA axis and causes glucocorticoid levels to elevate. Increased glucocorticoids constrict choroid vessels, which leads to ischemia of choroids and damage vascular endothelial cells, thus causing vasopermeability to increase. RPE dysfunction will occur as a result of abnormalities in the choroidal circulation. The large molecules including protein may enter the subretinal space through the damaged vessels and RPE.
