ABSTRACT
Simply relying on the introduction of online teaching resources on the platforms such as Chinese University Massive Open Online Course (MOOC) to carry out online teaching, it is easy to encounter problems that the teaching resources are inconsistent with the learning situation and teaching syllabus of the students majoring in medical statistics of Binzhou Medical University, the lack of interaction among students, and the untimely teaching feedback. Therefore, on the basis of integrating the MOOC resources, we established asynchronous small private online course (SPOC) online curriculum resources for medical statistics that were suitable for the students of our school. The blended teaching mode of "SPOC+QQ living broadcast" was carried out. Before and after the implementation, two rounds of questionnaires were conducted to understand students' teaching and learning needs and teaching effect evaluation of online teaching, and then the teaching mode was optimized. The results show that the blended teaching mode of "SPOC + QQ living broadcast" designed in this study has the advantages of rich teaching resources, high enthusiasm of students, flexible teaching interaction, timely teaching feedback, and diversified teaching evaluation, which provides a reference for the better development of online and offline blended teaching reform in the future.

ABSTRACT
Objective:To investigate the effects of different labeling conditions on the yield of Al 18F-labeled 1, 4, 7-triazacylononane-1, 4, 7-triaceticacid (NOTA)-prostate specific membrane antigen (PSMA)-137, and to determine the experimental condition for obtaining Al 18F-PSMA-137 probe in high yield. Methods:The effects of different pH values, buffer systems (acetic acid-sodium acetate buffer system and potassium hydrogen phthalate (KHP) buffer system), AlCl 3-ligand ratios, ligand amounts, ethanol volumes and reaction temperatures on the labeling rate were investigated in detail. Results:The pH value of the reaction solution had a significant effect on the labeling rate, and the optimal range was 4.0-4.5. When the pH value was higher than 4.5, the labeling rate decreased significantly. Both the acetic acid-sodium acetate buffer system and the KHP buffer system could be used to label NOTA-PSMA-137 with Al 18F, and the KHP buffer system obtained higher labeling rate. The ratio of AlCl 3-ligand affected the labeling rate, and the highest labeling rate could be obtained when the ratio of AlCl 3-ligand was 0.54-0.62. When the ratio of AlCl 3-ligand was fixed, increasing the amount of ligand could improve the labeling yield. Adding hydrophilic organic solvent ethanol to the reaction system could significantly increase yield, with the highest labeling rate being achieved at a volume of 100 μl ethanol. The most suitable reaction temperature was 100 ℃, and when the temperature raised to 110 ℃, the labeling rate decreased significantly. The most suitable labeling conditions for NOTA-PSMA-137 were as following: 25 μl KHP buffer (0.50 mol/L, pH=4.0), 7.0 μl AlCl 3 solution (20 mmol/L), 200 μl Na 18F solution (74-80 MBq) and 230 μg ligand NOTA-PSMA-137 were mixed in a vial, then stood for 5 min and 100 μl ethanol was added, and all reagents were heated at 100 ℃ for 10 min. The yield of Al 18F-PSMA-137 under above conditions were 85.7%-88.5%. Conclusion:Optimization of labeling condition can improve the yield of Al 18F-PSMA-137 and the stability of the labeling.
ABSTRACT
Fear memories are temporarily suppressed after repeated retrieval, a phenomenon known as memory extinction.How to reduce or even eliminate fear memory is the key to the treatment of fear related diseases such as post-traumatic stress disorder(PTSD). A single extinction training based on Pavlov's fear regulation task could only inhibit the expression of conditioned fear memory traces, but it could not eliminate the acquired conditioned fear memory. However, according to the reconsolidation theory based on memory, the retrieval-extinction paradigm has a more lasting effect on the erasure and rewriting of fear memory, and can effectively prevent the return of fear memory. Studies have shown that extraction-regression is closely related to a variety of neurotransmitter receptors such as glutamate receptor(GluR), dopamine receptor(DAR), L-type voltage-gated calcium channels(LVGCs) and cannabinoid. Moreover, its effect is closely related with factors such as retrieval-extinction memory stage. At present, most of the researches on extracted boundary conditions only stay at the level of behavior, with little understanding and exploration on the level of molecular mechanism. From the perspective of molecular neurobiology, with different stages of memory and different types of receptors and molecular mechanisms, this research reviewed the mechanisms of retrieval-extinction in recent years.It provided valuable signaling pathways, molecular targets and research directions for the treatment of fear-related diseases such as PTSD.

ABSTRACT
Objective:To explore the diagnosis, treatment and prognostic of pediatric intracranial atypical teratoid/rhabdoid tumor(AT/RT).Methods:A total of 15 pediatric patients with intracranial AT/RT were treated between January 2012 and June 2019 at the First Affiliated Hospital of Zhengzhou University.The clinical data were retrospectively analyzed.Overall survival (OS) rate and progression free survival (PFS) rate were calculated by adopting Kaplan- Meier method.The differences between the 2 groups were tested by performing Log- rank method, and the prognostic factors were analyzed by COX regression. Results:There were 12 males and 3 females, with the median age of 5.5 years (ranging from 8 months to 17.1 years). All patients underwent surgical resection.Gross-total resection (GTR) was achieved in 10 cases and subtotal resection (STR) was carried out in 5 patients.The conducted treatments were as follows: surgery+ radiotherapy+ chemotherapy+ intrathecal injection in 6 cases, surgery+ chemotherapy+ intrathecal injection in 4 cases, surgery+ radiotherapy in 2 cases, and surgery alone in 3 cases.Until January 2020, the median survival time of all the 15 patients was 18 months (ranged 1-27 months), and the survival rate was 33.3%.The 1-year OS rate and PFS rate for all 15 cases were 71.5% and 49.7%, respectively.The 2-year OS rate and PFS rate were 17.9% and 0, respectively. Log- rank analyses revealed that the 1-year OS rates of children less than 3 years old and those older than 3 years were 87.5% and 57.1%, respectively ( χ2=6.057, P=0.014). The 1-year OS rates of children with GTR and those with STR were 90.0% and 40.0%, respectively ( χ2=6.057, P=0.014). The 1-year OS rates of children with tumor dissemination and those without tumor dissemination were 100.0% and 33.3%, respectively( χ2=9.865, P=0.002). The 1-year OS rates of children in the standard-risk group and those in the high-risk group were 88.9% and 41.7%, respectively ( χ2=5.111, P=0.024). COX regression analyses proved that age, the extent of tumor resection, tumor dissemination and risk stratification are independent risk factors for prognosis [hazard radio( HR)=3.411, 3.795, 5.245, 3.397; P=0.025, 0.011, 0.001, 0.017]. Conclusions:Pediatric intracranial AT/RT is rare.The preliminary diagnosis and prognosis are difficult and poor, respectively.The complete resection of tumors with maximal safety remains the primary treatment.Age, the extent of tumor resection, tumor dissemination and risk stratification are independent prognostic factors for AT/RT children.
ABSTRACT
Objective:To explore the relationship between moral sense of life and prosocial behavior among medical students, and the multiple mediating effects of meaning in life and empathy.Methods:A total of 721 medical students from Weifang Medical University were tested with moral sense of life scale (MSLS), meaning in life questionnaire (MLQ), interpersonal reactivity index-C (IRI-C) and prosocial behavior tendency scale (PBTS). Common method bias test, Spearman correlation analysis and hierarchical regression analysis were conducted to analyze the data using SPSS 22.0 software, and PROCESS macro program was used to test the mediating effect of meaning in life and empathy between moral sense of life and prosocial behavior.Results:Moral sense of life, meaning in life, empathy and prosocial behavior were significantly positively correlated with each other( r=0.24-0.56, all P<0.01). Analysis of mediating effects revealed that moral sense of life affected prosocial behavior through three indirect pathways: the separate meditating effects of both meaning in life and empathy (the effect size=0.11, 0.06), accounting for 57.89% and 31.58% of the total indirect effect respectively), the chain mediating effect of meaning in life and empathy (the effect size=0.02), accounting for 10.53% of the total indirect effect. Meaning in life and empathy play a full mediating role in the relationship between moral sense of life and prosocial behavior. Conclusion:Moral sense of life can indirectly increase medical students′ prosocial behavior through meaning in life and empathy. Meaning in life and empathy exert a chain-mediating effect between moral sense of life and prosocial behavior.
ABSTRACT
Major depressive disorder is a mental illness characterized by depressed mood, lack of engagement in pleasurable activities, anhedonia, and cognitive-behavioral disorders. Currently, traditional pharmacological treatments for depression have a delayed therapeutic onset and low treatment effectiveness. (2R, 6R)-HNK, as a key metabolite of ketamine, can not only exert rapid and lasting antidepressant effects but also has no side effects such as hallucination and addiction caused by ketamine, which has potential clinical application values. Studies have found that the antidepressant effect of (2R, 6R)-HNK is closely related to the regulation mechanism of glutamate receptor and synaptic plasticity. Besides, the changes of downstream signaling pathways include the upregulation of brain-derived neurotrophic factor (BDNF) expression, dephosphorylation of eukaryotic elongation factor 2 (eEF2), and activation of the mammalian target of rapamycin (mTOR) play a key role in the antidepressant process of the drug. Understanding the molecular mechanisms underpinning (2R, 6R)-HNK's antidepressant effects will be invaluable for the identification of targets, which will drive the development of novel, effective, next-generation pharmacotherapies for the treatment of depression.
ABSTRACT
The rotary cell culture system(RCCS)was used to simulate the microgravity environment, and FRTL-5 cells were divided into simulated microgravity group(SMG)and normal gravity group(NG). FRTL-5 cells were harvested after treatment for 6, 12, 24, and 36 h, the cell viability was measured by MTT assay, and the cells cycles were detected by flow cytometry. The ultrastructure of FRTL-5 cells was observed under laser confocal microscope with FITC-labeled technique. The MTT assay showed that the proliferation of FRTL-5 cells was significantly inhibited after RCCS treatment for 6, 12, 24, and 36h compared with NG(P<0.05), in which the most obvious effect was observed at 24h. The flow cytometry showed that the proportion of FRTL-5 cells at G1 stage in RCCS group was increased significantly after 6, 12, 24, and 36h compared with NG(P<0.05), while the proportion of FRTL-5 cells at S stage was decreased significantly(P<0.05)except that cultured with RCCS for 6 h. The proportion of FRTL-5 cells at G2/M stage was decreased in early phase(6-12 hours)of RCCS culture, with the lowest at 12h and transient increase at 24h of RCCS culture. The laser confocal microscope revealed that there were local microfilament depolymerization, tension fibers decrease, structure disorder, cellular pseudopodia reduction, and irregular shape among FITC-labeled FRTL-5 cells cultured with RCCS for 36h.

ABSTRACT
Objective To investigate the effects of simulated microgravity by RCCS on proliferation and cell cytoskeleton of human HaCaT keratinocyte. Methods The rotary cell culture system (RCCS) was used to simulate the microgravity environment, and human HaCaT keratinocytes were divided randomly(random number) into the simulated microgravity group (SMG) and normal gravity group (NG). HaCaT cells in the two groups were harvested respectively after 32, 36 and 42 h culture. The HaCaT cells proliferation and cycles were detected by flow cytometry, the concentration of hb-EGF in supernatant was detected by ELISA, and the cell cytoskeleton was observed after 42 hours' culture under laser confocal microscope with FITC-labeled technique. SPSS 23.0 statistical software was used for statistical analysis, and P <0.05 was considered statistically significant. Results The flow cytometry showed that the proportions of human HaCaT keratinocytes in G1 and G2/M phases were increased while the proportion of HaCaT cells in S stage was decreased significantly after 32, 36 and 42 h RCCSculture compared with those in the normal gravity group. The HaCaT cells in G1 stage were declined along with incubation time. ELISA results showed that the hb-EGF concentration in HaCaT supernatant under simulated microgravity culture for 24 and 36 h was lower than that in the normal control group (P<0.01). The laser confocal microscope revealed that the HaCaT fluorescence intensity was decreased,and there were disordered microfilaments, structural ambiguity, pseudopodia reduction and irregularshape among FITC-labeled HaCaT cells cultured 42 h in RSSC compared with the normal gravity group.Conclusions RCCS simulated microgravity environment could inhibit the cell cycle transformation and proliferation of human HaCaT keratinocyte, affect the keratinocyte-secreting function, and induce alterations of the cell cytoskeleton.
