In order to observe the effects of the supernatant of WEHI-3 cell culture which contains IL-3 (interleukin 3), we have Performed some experiments by adding WEHI-3 supernatant to murine bone marrow cells culture. Cell culture of six days shows that the supernatant of WEHI-3 can promote adherence and proliferation of the stromal cells. There are 1.334?10~6 stromal cells/L in the culture which contained 20% WEHI-3 supernatant. Four kinds of stromal cells can be identified under both light microscope and SEM. Fibroblast-like cells which tend to be spindle-shaped with many filament-like and microvilli-like dendrites on the cell surface; Riticular-like cells which are irregular with some folds on the dendrites surface occasionally; Macrophage-like cells which are round with many phagocytic granules in the cytoplasm, and are characterized by positive ANAE staining, and many lamina-like folds and long filament-like dendrites on the cell sufrace; Fat cells are few in number, the cell body is ovoid with lipid droplet, and show strong cytoplasmic staining for Sudan black B, the cell surface is smooth. At the same time we have also observed the close contact between the hematopoietic cells and the stromal cells. In the culture without WEHI-3 supernatant, we have found few small adhered cells with less cytoplasm and weak enzyme activaties under light microscope, and with atrophied cell body and flat surface under SEM. The cell count of the stromal cells in normal culture is 58.83/mm~2. The results showed that WEHI-3 supernatant can promote the growth and proliferation of the stromal cells of murine bone marrow with some histochemical changes.

Objective To investigate the health-related quality of life (HRQOL), demographic characteristics, and health behaviors of the Chinese elderly to find out high-risk population and behaviors. Methods Data was collected from a cross-sectional survey performed in Jiangsu, Anhui, Gansu,Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan province. MOS SF-36 was used for HRQOL assessment, t test was used for HRQOL comparison between the elderly and the general population. Multiple stepwise linear regression analysis was used to evaluate the affecting factors. Results The HRQOL among the Chinese elderly were PF ( Physical Functioning) 79 ± 21, RP ( Role-Physical ) 68 ± 40, BP ( Bodily Pain) 72 ± 23, GH ( General Health) 57±22, VT ( Vitality ) 69 ± 20, SF ( Social Functioning) 79 ± 23, RE ( Role-Emotional ) 72 ±40, M H ( Mental Health)76 ± 18, which were lower than Sichuan Norm on 7 dimensions ( P ＜ 0. 05 ; except on M H dimension) and lower than Hangzhou Norm on 5 dimensions (P ＜ 0. 05 ;except on GH, VT, and MHdimensions). The important affecting factors included physical exercise, education level, medical history of chronic disease, age, race, marriage, body mass index ( BMI ), sleeping habits, and gender. Conclusions Compared with the general population, the HRQOL in the elderly might be lower. The health policy and community heahhcare services should focus on the elderly individuals with insufficient exercise, lower education level, chronic disease history, and ethnic minority, or widows. Health education should encourage them to improve physical exercise and sleeping behavior.
