Coding region instability determinant (CRD) is one of the influence factors of oncogene c-myc.Coding region instability determinant-binding protein (CRD-BP) can connect with CRD in order to protect CRD from nuclease attack,prevent rapid degradation of c-myc mRNA,and increase c-myc protein content.Beta-transducin repeats-containing protein (β-TrCP) can affect cell growth,differentiation,apoptosis and oncogenesis by regulating multiple signaling pathways and cell cycle.The overexpression of CRD-BP can upregulate the expression of β-TrCP and both of them play important roles in the tumorigenesis,progression,metastasis and invasion of colorectal cancer.

ObjectiveTo investigate the event-based prospective memory (EBPM) and time-based prospective memory (TBPM) in patients with Alzheimer' s disease (AD). MethodsTwenty patients with AD, 20 adults with amnesia mild cognitive impairment (aMCI) and 30 healthy adults with matched age and education level were assessed with a battery of neuropsychological tests including EBPM and TBPM tasks.ResultsCompared with healthy elders and patients with aMCI on performance of PM (2. 23 + 0. 77,4.83 ±1.09;1.00±1.03,3. 10 ± 1.52) and episodic memory(0. 70 ±0. 12,0.66 +0. 16;0.45 ±0.07,0.54±0. 10), AD patients were all impaired in PM and episodic memory(0.20 +0.41,2.05 ± 1.43;0.33±0. 12,0.32±0. 10), and were impaired in EBPM more significantly (t=-2.792, P<0.01;t =-10. 761 ,P <0. 01 ). ConclusionsThese results suggest that AD patients show deficits of PM, but their EBPM is impaired more significantly. EBPM impairment may be an early diagnostic of AD.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.

Objective:To explore the mental health status of overseas medical students during the COVID-19 epidemic, so as to provide references for the improvement of their mental health level.Methods:Symptom Checklist 90 (SCL-90) was applied to make a survey online among 118 overseas medical students. SPSS 19.0 was used for statistical analysis, and independent sample ttest and univariate analysis were conducted between the groups. Results:The analysis showed that during the COVID-19 epidemic, the scores of SCL-90 factors of overseas medical students in China were significantly higher than those of Chinese youth norms ( P<0.001). The top four scores were as follows: obsessive-compulsive symptoms > paranoia ideation > interpersonal sensitivity > depression. The positive screening rate for SCL-90 of the overseas students was 40.4%. The scores of male overseas students were significantly higher than those of female students ( P<0.01). The scores of overseas students living outside China at present were significantly higher those of students living in China and on campus ( P<0.001). Conclusion:The mental health status of the overseas medical students needs to be attached great importance during the COVID-19 epidemic. Targeted psychological counseling and intervention should be given to foreign students both staying outside China and those on campus.

BACKGROUND:The research at home and abroad for appropriate immature myocardial cardioplegia has no breakthrough, and it may be a better mean to improve the protection effect of existing cardioplegia on immature myocardial by adding ingredients. Adenosine can reduce ischemia and neutrophil-mediated reperfusion injury, and salvia miltiorrhiza can reduce the content of ischemic myocardial lipid peroxide and increase the scavenging of myocardial cells to oxygen radical. OBJECTIVE:To investigate the protection effect of improved myocardial protection fluid containing adenosine and salvia miltiorrhiza on the heart, liver and kidney. METHODS:Sixty cases of infant open heart operation of the first time were randomly divided into three groups, 20 cases in each group. The adenosine group received the improved myocardial protection fluid added with adenosine, the combination group received the improved myocardial protection fluid added with adenosine and miltiorrhiza salvia, and the control group received the improved myocardial protection fluid in the same volume. The blood samples were taken at the time before anesthesia induction, 30 minutes after cardio pulmonary bypass beginning, 1 hour after cardio pulmonary bypass end and 24 hours after cardio pulmonary bypass end. The serum levels of the creatine kinase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, tumor necrosis factor-α, interleukin-6, interleukin-8 and interleukin 10 were detected. RESULTS AND CONCLUSION:The serum levels of the alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and creatine kinase in three groups were increased, but the control group was increased significantly (P<0.01), and there were significant differences between adenosine group and combination group (P<0.05);the levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 were significantly increased after operation (P<0.05). The levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 in the control group were significantly higher than those in the adenosine group and combination group before induction and at the same time point (P<0.01);at 3 minutes and 24 hours after cardio pulmonary bypass, the level of interleukin-10 was increased in three groups, but the level of interleukin-10 in the adenosine group was significantly higher than that in the control group (P<0.01). The results indicate that improved myocardial protection fluid has great protection effect on immature myocardial, and can significantly reduce the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-8, promote the secretion of interleukin-10 that can inhibit inflammatory cytokine and can significantly reduce the inflammatory response caused by cardiopulmonary bypass. So the improved myocardial protection fluid has protection effect on important organs, such as heart, lung, liver and kidney.
