Biological clock genes are essential for regulating various biological processes such as sleep,endo-crine metabolism,and cell proliferation and differentiation.These genes govern the circadian system with approximately 24-h cycles in all living organisms.Recent studies have focused on uncovering the connection between circadian rhythms and tumors.Although the expression of circadian rhythm genes and their proteins is stable in normal tissue cells,in tumor cells,such as colorectal cancer tissues,the expression of these genes is often abnormally up-regulated or down-regulated,which indicates a strong correlation between the abnormal expression of clock genes and the incidence and progression of cancers.In fact,the disruption of the balance of cellular metabolism,cell cycle,cell proliferation,and apoptosis due to the abnormal expression and mutation of biological clock genes can trigger the development of colorectal cancer.In addi-tion,the disrupted circadian rhythm induced by abnormal tumor cell growth can further the advancement of disease,inva-sion,and even metastasis.Our review summarizes the functions and mechanisms of prominent clock genes in the initiation and progression of colorectal cancer based on the recent studies to provide a foundation for the development of personalized chronotherapy regimes encompassing the body's innate biorhythms in standard clinical cancer treatment procedures so as to,ultimately,optimize treatment efficacy and extend patient's life expectancy.

Objective To investigate the comprehensive effect and impact path of family environment,rearing style and personality on adolescents with mental disorder.Methods A sample of 200 adolescents with mental disorders and 228 normal adolescents were tested with Family Environment Scale (FESCV),Family Upbringing Style Questionnaire (FUSO),Big Five Personality Questionnaire (NEO-FFI-R) and Psychological Symptom Inventory-100(PSI-I00).Regression analysis and path analysis were used to explore influence and path of rearing style,family environment and personality on mental health.Results The total score PSI-100 in case group (204.0±68.6) was higher than that in control group (146.9±38.4)(t=10.43,P＜0.01).Regression analysis revealed that mental health was affected by rearing style (R2 =0.208) such as mother supervision-control (β =-0.249),father understands-blame (β =-0.195),mother warmth-wildness (β=-0.228) and mother acceptance-rejection (β=0.201),family environment (R2 =0.244) such as conflict (β=0.309),organization (β=-0.196) and expressiveness (β=-0.141),and personality traits (R2 =0.452)such as neuroticism (β=0.412),agreeableness (β=-0.237) and conscientiousness (β=-0.203).Path Analysis showed that personality traits directly affected mental health (β=-0.90),parenting style indirectly influenced mental health (β=0.51) by personality,the family environment had direct (β=0.20) and indirect (β=0.72) effects on mental health,and the model fits well (x2/df =2.160,RMSEA =0.052,GFI =0.88,AGFI =0.84,PGFI =0.67,NFI =0.91,RFI =0.89,IFI =0.95,TLI =0.94,CFI =0.95),and three factors explained 61％ of variation on symptom total score.Conclusion The family environment,family upbringing style and personality traits have significant effect on the adolescent's mental disorder.The personality traits are the most important variables affecting mental health family upbringing style affect mental health indirectly through personality traits,and family environment directly and indirectly affected on the mental health.

Objective To explore family environment,parenting style,and personality of the patients with internalizing and externalizing mental disorders.Methods 137 adolescents with internalizing mental disorder(IMD),63 adolescents with externalizing mental disorder(EMD) and 228 normal subjects (control group) were investigated with Family Environment Scale-Chinese Version (FES-CV),Family Upbringing Style Questionnaire (FUSQ) and the NEO Five Factor Inventory (NEO-FFI).Results (1) The IMD group scored significantly lower on the cohesion (6.17 ± 2.68),active recreational orientation (3.84 ±2.50),moral-religious emphasis (4.48± 1.65),organization (5.35±2.30),expressiveness (4.60±2.00),achievement orientation (5.31 ± 1.84),and higher on the conflict (4.01 ± 2.38) than control group (P＜ 0.05).The EMD group scored only higher on the conflict (4.01±2.38) than control group (P＜0.05).(2) The all dimensional scores(apart from the parent's expect-demanding) of the IMD group were significantly lower than that of control group on the FUSQ (P＜0.05).The scores on the mother's democracy-authoritarian,parent care-protect,catholic-indulgences,parental-control,and expect-demanding were significantly lower in the EMD group than those in the control group (P＜0.05).(3) Relative to the control group,the IMD group got lower scores on the agreeableness (42.02±5.01),conscientiousness (38.91±8.01),and extraversion (35.17±8.57),and higher score on the neuroticism (40.10±8.55);the EMD group got lower scores on the agreeableness(42.75±5.12),conscientiousness (39.95±8.27) and openness (40.00±6.75).Conclusion Adolescents with mental disorders are living in conflict and discord family environment,feel more negative parenting such as authoritarian,harsh,indulgence,control,and demanding,and show some unhealthy personality such as low agreeableness,low conscientiousness,and high neurotic.
