| 中文摘要: |
| HBV感染是指血清中HBsAg和HBV DNA检测阳性.然而随着高灵敏分子生物学技术在HBV检测中的应用,发现部分HBV感染者血清HBsAg阴性,但血清或肝组织HBVDNA持续存在,从而提出隐匿性HBV感染(occult hepatitisB virus infection,OBI)的概念[1].HBsAg阴性的HBV感染与许多临床情况有关,由于HBsAg阴性HBV感染难以用常规方法检出,成为较复杂的流行病学和临床问题[2].目前OBI的流行病学研究主要集中于OBI在不同人群患病率的横断面调查,由于选取研究对象的方法不-,检测指标及方法各异,造成结果差别很大.本文就近年来OBI的流行病学调查方法、发病情况等研究进展进行综述. |

| To explore the improvement of clinical symptoms after treatment on patients with depression under the latent growth curve modeling.514 patients were studied with Hamilton Depression Rating Scale for depression and nonlinear conditional.Latent growth curve modeling was constructed to assess the features of outcome growth trajectory and possible related influencing factors.Results indicated that the outcome measure showing nonlinear growth trajectory and rapid drop during the first follow-up period and then declining or leveling off for the rest of the observation period on symptoms of anxiety,cognitive disturbance,retardation,sleeping disorder and HAMD scores.The variances of both latent intercept and the slope growth factor were statistically significant,indicating they varied across individuals.Gender did not show significant effect on both the intercept and the slope growth factor for the six outcomes,while age had a significant positive effect on initial weight loss,sleep disorder and HAMD scores at the baseline (0.015,0.048 and 0.068,P＜0.05) survey.Marriage showed significant positive effect on intercept factor of anxiety symptoms (0.563,P＜0.05) but negative effect on slope growth factor (-0.244,P＜0.05) while family history had significant positive effect on intercept factor regarding retardation (0.471,P＜0.05).The level of received education had a significant negative effect on intercept factor of anxiety symptoms and HAMD scores (-0.424 and-0.914,P＜0.05).Latent growth curve models allowed the researchers to study the overall growth trajectory as well as the captured individual differences on these trajectories over time,that also provided a powerful tool for the analysis on longitudinal data. |
