ABSTRACT
Guided by the development of new medical science proposed by Ministry of Education and the "Education and Training Plan for Excellent Doctors 2.0", shifted from treatment-oriented to whole life-health cycle, we have explored curriculum ideological and political education in metabolic-related curriculum chain. Firstly, we constructed a core teaching team and had the training of curriculum ideological and political education. The top-level design was made with the integration of moral education into medical education. Secondly, the syllabus was comprehensively revised, containing the connotation of "morality education". The elements relevant to curriculum ideological and political education hidden behind professional courses were excavated. Finally, the mixed teaching mode of online combining with offline was carried out. Metabolism-related curriculum chain, focused on "metabolism, diabetes, obesity and patient education", formed a progressive link from basic medical science to practice to clinical, strengthening the "prevention, treatment and health care" based "one health" philosophy and giving full play to the implicit curriculum ideological and political education hidden behind professional courses. Our practice shows that the implementation of curriculum ideological and political education in metabolism-related curriculum has been accepted by students, and curriculum ideological and political education has been become part of professional courses. The "gene chimera" mode for curriculum ideological and political education incorporation into professional courses needs to be infiltrated imperceptibly, and the effect will be visualized in the future.
ABSTRACT
The mammalian brain is heterogeneous, containing billions of neurons and trillions of synapses forming various neural circuitries, through which sense, movement, thought, and emotion arise. The cellular heterogeneity of the brain has made it difficult to study the molecular logic of neural circuitry wiring, pruning, activation, and plasticity, until recently, transcriptome analyses with single cell resolution makes decoding of gene regulatory networks underlying aforementioned circuitry properties possible. Here we report success in performing both electrophysiological and whole-genome transcriptome analyses on single human neurons in culture. Using Weighted Gene Coexpression Network Analyses (WGCNA), we identified gene clusters highly correlated with neuronal maturation judged by electrophysiological characteristics. A tight link between neuronal maturation and genes involved in ubiquitination and mitochondrial function was revealed. Moreover, we identified a list of candidate genes, which could potentially serve as biomarkers for neuronal maturation. Coupled electrophysiological recording and single cell transcriptome analysis will serve as powerful tools in the future to unveil molecular logics for neural circuitry functions.

To tackle the problems found during cell biology teaching in English for medical oversea students,following teaching principles and management regulations were proposed:strength-ening the basic knowledge,improving the teaching materials,optimizing the teaching contents,clev-erly designing the teaching scheme ,rationalizing the teaching schedule ,elaborately preparing and giving the lessons,enhancing the class interaction between teachers and students,and timely collect-ing teaching feedback. The above measures provided theoretical foundations for the effective education and training of medical oversea students.
ABSTRACT
Experimental course for integrative life science curriculum is designed for medical students ,which integrates basic knowledge and skills of cellular biology,biochemistry,genetics,molec-ular biology,molecular genetics,and immunology disciplines. Tongji University School of Medicine start-ed to implement integration-based new curriculum system since 2010. This article discussed on teaching philosophy,teaching content,teaching methods,teaching team construction and explored the effect and significance of experimental course for integrative life science curriculum.
ABSTRACT
Objective To evaluate the significance of carbohydrate antigen 50 (CA50) expression in colorectal carcinoma. Methods Immunohistochemical staining was used to detect CA50 expression in 10 cases of normal colorectal mucosa and 40 cases of cancer mucosa. Results The expression of CA50 increased in normal colorectal mucosa, cancer distant mucosa, cancer adjacent mucosa and cancer mucosa, and there were significant differences among them (P<0.05). The expression of CA50 in colorectal carcinoma was correlated with the degree of differentiation, Duke's stage and lymphatic metastases (P<0.05). Conclusion The expression of CA50 can be used as a valuable index in evaluating the biological characteristics and prognosis of colorectal carcinoma.
ABSTRACT
This TSR1 gene associated with the secretion of Proteins of the yeast Yarrowia lipolytica was deleted. Transformation of a Y. lipolytica strain.with the disrupted tsr1 fragment resulted in the substitution of partially deleted TSR1 gene for the wild-type TSR1 gene on the chromosome. The result of southern hybridization show that the tsr1 mutants have been constructed. The isolation of these mutants would be useful for studing the function of TSR1 gene in yeast Y. lipolytica.
