OBJECTIVETo investigate the coping strategies of the community-based population in Shenzhen.

METHODSTotally 5,940 subjects from the communities in Shenzhen were sampled and tested with the Simplified Coping Style questionnaire.

RESULTSThe most common coping strategies adopted by the community residents in Shenzhen were "consoling themselves" (33.1%) and "looking at the bright side of things" (31.4%), and the least adopted coping strategy was "relieving distress by smoking, drinking, taking medicine and eating" (57.8%); the strategies left out from their choices were mostly negative strategies. The scores for positive coping strategy factors of community residents in Shenzhen were greater than those of negative ones, with a mean difference of 0.43. The scores of both positive and negative coping strategy factors of these residents were significantly lower than those of general population in other mainland cities (P<0.001), with mean differences of 0.12 and 0.36, respectively.

CONCLUSIONThe community residents in Shenzhen adopt mostly positive strategies for coping with frustration, which benefit their status of self-rated health.

To improve the stability of amino acid ester derivatives of DB02, a series of 24 amide derivatives of DB02 amino acids as non-nucleoside HIV-1 reverse transcriptase inhibitor were designed and synthesized based on bioisosterism by replacing amino acid ester scaffold with more stable amide bond. The anti-HIV-1 activity of these compounds was evaluated by MTT assay and counting the number of syncytia. Most of the target compounds showed a potential anti-HIV-1 activity, among which compounds 2d, 2i, 2l, 2s, and 2w had better antiviral effect than lead compound DB02, with a therapeutic index > 1 000.00. Finally, the structure-activity relationship of these compounds was discussed, which provided new ideas for the further development of DB02 derivatives.
