Prognostic value of aldo-keto reductase family 1 member B10 (AKR1B10) in digestive system cancers: A meta-analysis

Background:Numbers of studies have reported that the expression of aldo-keto reductase family 1 member B10 (AKR1B10) is abnormal in digestive system cancers, and could be used as a prognostic biomarker. However, the results are argued. Therefore, we conduct a meta-analysis to comprehensively evaluate the prognostic value of high AKR1B10 expression for overall survival (OS), disease specific survival (DSS), and disease-free survival/recurrence-free survival (DFS/PFS) in digestive system cancers.Methods:Hazard ratios (HRs) with its 95% confidence intervals (CIs) were calculated to assess the prognostic value of AKR1B10 by using the random effects model. The STATA version 12.0 software were used to perform all the analyses.Results:Eleven articles including 1428 patients involved in this meta-analysis. The pooled analysis suggested that high AKR1B10 expression was not associated with OS (HR: 1.18; 95% CI: 0.69–2.00) and DFS/PFS (HR: 1.08, 95% CI: 0.67–1.76) in digestive system cancers. However, Further analysis revealed that high AKR1B10 expression indicated poor OS in oral squamous cell carcinomas (OSCC) (HR: 2.92, 95% CI: 1.86–4.58) and favorable DSS in hepatocellular carcinoma (HCC) (HR: 0.71, 95% CI: 0.52–0.97).Conclusions:The prognostic value of high AKR1B10 expression varied in different types of digestive system cancers. Further studies exploring the prognostic role of AKR1B10 in digestive system cancers are needed.

Effect of personality on oral health–related quality of life in undergraduates

Objectives:To evaluate the effects of personality traits and other variables on oral health–related quality of life (OHRQoL) of Chinese undergraduates aged 17 to 24 years with no history of orthodontic treatment.Materials and Methods:A total of 443 undergraduate students aged 17 to 24 years were selected and completed a two-section questionnaire: the Eysenck Personality Questionnaire Short Scale Chinese version and the Oral Health Impact Profile–14 Chinese version (OHIP-14). Malocclusion severity was assessed via clinical examination using the dental health component (DHC) and esthetic component of the Index of Orthodontic Treatment Need (IOTN). Severe dentofacial deformities that required orthognathic surgery were excluded.Results:The total and all dichotomized OHIP-14 dimensions correlated closely with the neuroticism personality traits (P < .001). The total and some subscales of OHIP-14 were related with psychoticism. Women had higher OHIP-14 scores than men, especially in the normal occlusion group. Nevertheless, men with more severe malocclusions had higher scores that were similar to those of women. OHRQoL was significantly different between the major of dentistry and other majors.Conclusions:Personality affects comprehensive OHRQoL, and the most significant predictor is neuroticism. Female young adults have worse OHRQoL than male young adults, especially among those with mild malocclusion.     

精神分裂症与心境障碍患者精神残疾状况对照研究

目的 探讨精神分裂症与心境障碍所致精神残疾患者的临床特征.方法抽取在我院进行精神残疾评定的97例精神分裂症患者设为精神分裂症组,97例心境障碍患者设为心境障碍组,采用世界卫生组织残疾评定量表Ⅱ评定精神残疾状况.结果 精神分裂症组单身、病前有个性缺陷、丧失劳动能力、1级残疾比例及世界卫生组织残疾评定量表Ⅱ总分、理解与交流、与他人相处、社会参与领域评分均显著高于心境障碍组(P＜0.05或0.01);受教育年限、病程均显著低于心境障碍组(P＜0.01).结论精神分裂症与心境障碍均是导致患者出现不同程度精神残疾的重性精神疾病,两者致残的病程及残疾程度等有所不同,但均应作为高危人群进行重点防控.
