OBJECTIVETo evaluate the effects of health promotion for eight years on cardiovascular diseases based on the changes in knowledge (K), attitude (A) and behavior (B) (KAB) before and after intervention in rural population of Fangshan, Beijing.

METHODSFive townships in Fangshan District, Beijing were divided into intervention and control communities with cluster sampling. Totally 772 farmers were selected randomly for interviews with a questionnaire of KAB, including 424 in the intervention communities (IC) and 348 in the control communities (CC) in 1992. After community-based health promotion and education on cardiovascular prevention for eight years, 895 farmers, including 431 in IC and 464 in CC, were selected randomly again in 1999 to be interviewed with the same questionnaire of KAB used in 1992.

RESULTSFrom 1992 to 1999, knowledge of cardiovascular diseases was significantly improved in residents of IC (P < 0.01) and CC. Compared to the residents in CC, there was a net increase in knowledge in residents of IC. Significant improvement was found in 10 and 11 of the 18 items of knowledge in males and females (P < 0.01), respectively. Level of knowledge in cardiovascular diseases was significantly higher in the residents of IC than those of CC in 1999. Proportions of those with positive attitudes and appropriate behaviors were significantly elevated in the residents of IC (P < 0.01), as well as prevalence of smoking and alcohol drinking decreased. However, as compared to CC, attitude and behavior in most aspects in the residents of IC changed positively, but in few aspects changed negatively. It suggested knowledge improved better than attitude and behavior changed.

CONCLUSIONSCommunity-based health promotion and education for a longer term had obvious effects on improvement of knowledge in cardiovascular disease for rural population, but slower effects on changes in attitude and behavior, which suggested there still existed certain barriers to transform knowledge into healthy behavior.

To assess targeting of an epothilone folate conjugate (BMS-753493) to the folate receptor (FR)-overexpressed tumor in mice bearing both FR+ and FR- tumors, a series of experiments were conducted by quantitative whole-body autoradiography (QWBA) and LC-MS/MS following i.v. administration of BMS-753493 or its active moiety, BMS-748285 in mice bearing FR+ (98M109) and FR- (M109) tumors. QWBA showed [H]BMS-753493-derived radioactivity was extensively distributed to various tissues. The FR over-expressing 98M109 tumors showed consistently higher level of radioactivity than FR-negative tumors (., M109 tumors) up to 48 h post dose of [H]BMS-753493, despite the magnitude of difference between the tumors is relatively small (generally 3~5-fold). The radioactivity level in 98M109 tumors was 2~12-fold of normal tissues except intestine/content at 48 h post dose. No selective radioactivity uptake into 98M109 tumors over M109 or normal tissues was observed after i.v. administration of the active epothilone, [H]BMS-748285. LC-MS/MS measurements demonstrated that the concentrations of BMS-748285, presumably from hydrolysis of the folate conjugate, in 98M109 tumors were greater than those in M109 tumors after i.v. administration of BMS-753493 (2-3-fold) whereas no differential uptake in the tumors following BMS-748285 administration. Those data were consistent with radioactivity determinations. Those results demonstrated that the folate conjugation in BMS-753493 enabled moderately preferential distribution of the active epothilone to FR over-expressing 98M109 tumors, thereby supporting targeted delivery of cytotoxics through the folate receptor.
