Objective To investigate the effect of state anxiety and trait anxiety on attentional orienting of heroin addicts. Methods State anxiety and trait anxiety was measured by State-Trait Anxiety Inventory (STAI). Forty heroin ad?dicts (36 males and 4 females) and 40 healthy controls (36 males and 4 females) participated in cue-target task. Atten?tional orienting and reorienting were measured in valid cue trials and invalid cue trails. Results Heroin addicts had sig?nificantly greater state anxiety [(42.65 ± 6.58) vs. (36.60 ± 8.91)] and trait anxiety [(44.43 ± 7.67) vs. (37.00 ± 8.63)] values than controls (P<0.05). The state anxiety was significantly correlated with orientation RT difference (r=-0.259, P=0.020) and disengaging/reorientation RT difference (r=0.333, P=0.003) in heroin addicts. Trait anxiety was also significantly cor?related with orientation RT difference (r=-0.248, P=0.026) and disengaging/reorientation RT difference (r=0.356, P=0.001) in heroin addicts. Conclusion Heroin addicts have significantly greater anxiety than healthy controls. Both their state anxiety and trait anxiety are associated with attentional orienting and disengaging/reorienting.

Objective To study the prevalence of retinopathy of prematurity (ROP) in preterm infants in Xiamen, Fujian. Design Retrospective case series. Participants From Oct. 2004 to Dec. 2008, 375 infants with birth weights ≤2500g or gestational age ≤32w were screened in Xiamen the First Hospital. Methods Initial examinations with the binocular indirect ophthalmoscopy and the scleral depression began at 4~6 weeks after birth or at 32 weeks postconception. All infants were followed-up until a stable retinal situation was reached. Main Outcome Measures The prevalence of ROP. Results Retinopathy of prematurity was detected in 10.93% of 375 neonates, including 18 eyes of stage 1, 48 eyes in stage 2, 14 eyes in stage 3, 2 eyes in AP-ROP. The prevalence of ROP in the infants with the birth weight ≤1000g, 1001-1500g and 1501-2000g was 45%, 17.07%, 7.01%, respectively; the occurrence rate of ROP in the infants with the gestational age ≤28 weeks, 29-30 weeks, 31-32 weeks, 33-34 weeks was 34.48%, 2.07%, 12.71%, 8.25%, respectively. Conclusions Earlier screening for ROP is very important. Low birth weight and young gestational age are the most important risk factors in the development of ROP.

Objective To observe the effect of Kechuanning Oral liquid on the expression of P13K in CD4+and CD8+T cells of asthma rats induced by respiratory syncytial virus (RSV), and explore its mechanism of preventing and treating asthma induced by virus. Methods SD rats were randomly divided into phosphate-buffered saline (PBS) control group, model group, dexamethasone and salbutamol group (positive drug group), and Kechuanning oral liquid group. Ovalbumin asthma rats model was built and induced by RSV. CD4+and CD8+T cells were separated by magnetic beads method. The expressive level of PI3K-110αin T cells was detected by immumofluorescence method with flow cytometry. Results Compared with PBS control group, positive drug group and Kechuanning oral liquid group, the CD4+and CD8+T cells percentage and the expression level of PI3K-110α in CD4+ and CD8+T cells of model group were significantly higher. The differences were statistically significant (P<0.01). The CD4+and CD8+T cells percentage was not associated with the expression level of PI3K-110α in CD4+ and CD8+T cells of each group by Pearson correlation analysis. Conclusion The CD4+ and CD8+T cells involve in the asthma immunity balanced modulation, and the level of PI3K expressed by CD4+ and CD8+T cells increase distinctly. Kechuanning oral liquid can restrain the expression of PI3K in CD4+ and CD8+T cells, which might be one of the immunologic mechanisms of treating asthma.
