Objective To assess the relationship between parental HIV/AIDS and psychosocial adjustment of children in rural central China. Methods Participants included 296 double AIDS orphans (children who had lost both their parents to AIDS), 459 single orphans (children who had lost one parent to AIDS), 466 vulnerable children who lived with HIV-infected parents, and 404 comparison children who did not experience HIV/AIDS-related illness and death in their families. The measures included depressive symptoms, loneliness, self-esteem, future expectations, hopefulness about the future, and perceived control over the future. Results AIDS orphans and vulnerable children consistently demonstrated poorer psychosocial adjustment than comparison children in the same community. The level of psychosocial adjustment was similar between single orphans and double orphans, but differed by care arrangement among double orphans. Conclusion The findings underscore the urgency and importance of culturally and developmentally appropriate intervention efforts targeting psychosocial problems among children affected by AIDS and call for more exploration of risk and resilience factors, both individual and contextual, affecting the psychosocial wellbeing of these children.

CDK11p58, a CDK11 family Ser/Thr kinase, is a G2/M specific protein and contributed to regulation of cell cycle, transcription and apoptotic signal transduction. Recently, CDK11p58 has been reported to exert important functions in mitotic process, such as the regulation of bipolar spindle formation and sister chromatid cohesion. Here, we identified p21 activated kinase 1 (PAK1) as a new CDK11p58 substrate and we mapped a new phosphorylation site of Ser174 on PAK1. By mutagenesis, we created PAK1174A and PAK1174E, which mimic the dephosphorylated and phosphorylated form of PAK1; further analysis showed PAK1174E could be recruited to myosin V motor complex through binding to dynein light chain 2 (DLC2). PAK1174E could accelerate the mitosis progression in a nocodazole blocked cell model, while PAK1174A exhibited an opposite role. Our results indicated PAK1 may serve as a downstream effector of CDK11p58 during mitosis progression.
