Objective:To evaluate the reliability and validity of the Chinese version of the Personal and Social Performance scale (PSP-CHN) in patients with schizophrenia.Methods:Totally 165 out-patients and in-patients meeting the DSM-IV-TR criteria for schizophrenia were entered in the study.Ten of subjects was included the intra-rater reliability training.The Global Assessment of Functioning Scale (GAF) was regarded as the' gold standard' to investigate the validity of PSP-CHN,and the Positive and Negative Rating Scale was used to assess the severity of disease to explore the correlative validity,in the other 155 subjects.Five to seven days after the first PSP-CHN interview,the second PSP-CHN was evaluated by another investigator to assess the test-retest reliability among 66 subjects.Twenty-seven subjects with the score of Positive and Negative Syndrome Scale (PANSS) more than 60 were followed up for 8 weeks of standardized pharmacotherapy.By the end of 8 week of treatment,the PANSS and PSP-CHN were assessed again to explore the sensitivity of PSP-CHN.Results:The internal consistency (Cronbach α=0.84) and the inter-rater reliability (κ value=0.56,ICC=0.94 for PSP-CHN total score) were good.The test-retest reliability was high [intraclass correlation coefficient (ICC) of 0.95].The scale showed good construct validity with statistically significant correlations with the Global Assessment of Functioning Scale (GAF) (ICC of 0.95).The PSP-CHN score had a good negative correlation with the PANSS total score(r=-0.79,-0.57,-0.63 and -0.71,respectively,P<0.01).After 8 week treatment,PSP-CHN total score was increased with the improvement of PANSS,and the responder showed higher increasing of PSP-CHN total score (21.2) than those partial responder(10.2),significantly.Conclusion:The Chinese version of the PSP-CHN is a convenient and valid instrument to assess the personal and social functions of stabilized and acute patients with schizophrenia.

Colon cancer is a common malignant tumor in the world, however, its pathogenesis still needs further research. FEZF1- AS1 is highly expressed in colon cancer and other malignant tumors, and is associated with clinicopathological features and prognosis of colon cancer patients. In addition, FEZF1- AS1 promotes the proliferation, invasion and migration of colon cancer cells, regulates the cell cycle and inhibits apoptosis through various mechanisms, suggesting that FEZF1- AS1 may be a new important molecular biomarker and a potential therapeutic target for colon cancer. This article reviews the advances in the study of function and mechanism of FEZF1- AS1 in colon cancer.

Objective: To explore the related factors of myopia among children and adolescents in Yunnan Province, and to predict and evaluate the influencing factors, so as to provide a scientific theoretical basis for the prevention and control of myopia. Methods: From March 9 to 14, 2023, 848 students from 6 primary and secondary schools in Dali and Lijiang of Yunnan Province were selected by multi stage stratified random cluster sampling method for visual acuity detection and questionnaire survey on myopia related factors. Multivariate Logistic regression analysis was used to establish a Nomogram prediction model for the selected influencing factors. Results: The overall myopia rate of the respondents was 68.3%, the myopia rate of boys (63.4%) was lower than that of girls (72.9%), and the myopia rate of primary school students (46.7%) was lower than that of junior high school students (81.1%), and the difference was statistically significant（ χ 2=8.71, 108.07, P <0.05). Daily eye exercises, activities outside the teaching building during recess, having daily sleep time of 7-9 and >9 h, having both parents without myopia were negatively correlated with the occurrence of myopia in children and adolescents in Yunnan Province ( OR=0.64, 0.63, 0.56, 0.28, 0.48, P < 0.05 ). The reading and writing time after school ≥3 h per day and parents unrestricted time to play video games were positively correlated with myopia ( OR=1.94, 1.78, P <0.05). Based on the influencing factors, a Nomogram prediction model was established to quantitatively evaluate the risk of myopia. The results showed that greater risk for myopia was associated with sleep duration, parental history of myopia, and the time spent reading and writing after school every day. Conclusion Both genetic factors and environmental factors are related to myopia in children and adolescents. The prediction model of nomogram is beneficial for screening high risk factors of myopia and taking corresponding prevention and treatment measures.

Objective To assess ocular biometric parameters among primary and secondary school students from Naxi,Bai and Han ethnic groups in Yunnan Province.Methods The school-based study was conducted in October 2020.A total of 724 second-,third-and seventh-graders were selected from Dali and Lijiang,where Bai and Naxi ethnic groups inhabit,using a stratified cluster sampling method to receive questionnaire surveys and eye examinations.Non-cycloplegic spherical equivalent(SE),axial length(AL),anterior chamber depth(ACD),corneal radius of curvature(CR),central corneal thickness(CCT),white-to-white(WTW)distance,and the AL/CR ratio were measured.Covariance analysis was used to examine the differences in SE and ocular biometric parameters in terms of ethnicity,sex and grade,while Pearson correlation was used to test the associations among the said indicators.Results There were no significant differences in daily outdoor time,screen time and sleep time among the three ethnic groups regardless of grades(all P＞0.05).The mean CCT of Naxi students was lower than that of Han and Bai students[grade 2 and grade 3:(542.48±39.76)μm vs.(553.81±31.83)μm and(559.27±32.79)μm;grade7:(538.86±34.91)μm vs.(547.41±33.55)μm and(548.26± 32.98)μm,all P＜0.05],while no significant differences were found in the other ocular biometric parameters among the three ethnic groups(all P＞0.05).Among the seventh-graders,the SE,AL and AL/CR ratio of Naxi students were signifi-cantly different from those of Han and Bai students(all P＜0.05).The AL,CR,ACD,CCT,WTW distance,and mean SE were lower in girls than in boys(all P＜0.05).Compared with grade 2 and grade 3,students of grade 7 had longer AL,deeper ACD and thinner CCT(all P＜0.05),while no significant differences were found in CR and WTW distance(all P＞0.05).Correlation analysis showed that the AL/CR ratio was highly correlated with SE(r=-0.78,P＜0.05).Conclu-sion Multiethnic primary and secondary school students may face similar environmental risks.Yet,disparities in ocular biometric parameters caused by ethnicity,sex and age should be noted.
