On-line and off-line blended teaching is one of the directions for future experimental teaching mode reform in universities. Blended teaching is characterized by systematic course design, repeatable knowledge nodes, autonomous learning and frequent interaction between teachers and students. The on-line and off-line blended teaching course of Biochemistry Experiments in Zhejiang University includes massive open online course (MOOC), off-line comprehensive series of experiments and independent experiments design and practice. The blended teaching practice of this course expanded experimental teaching content, developed standardized preparation, process and assessment mechanism, and promoted shared application of the course.

As the content of static biochemistry is boring and traditional cramming education fails to draw the attention of students, we divided the course into small units and then made full use of "micro-teaching" resources such as multimedia slides, pictures, objects, experimental demonstrations and animations of the biochemical principles. The method created a "micro-teaching" environment, which combined boring static knowledge with vivid dynamic elements, thus producing a strong sensory impact on students, highlighting the knowledge in their mind, prompting students' participation, and greatly improving the teaching effects. This article introduces the goals and development process of this teaching method, and takes "Protein Denaturation and Renaturation" as an example to demonstrate the design and implementation process of the "micro-teaching", which seems to be of great significance to the improvement of the teaching quality of biochemistry course and serves as a reference for reform in other courses.

Anaerobic digestion is another important anaerobic catabolism pathway besides lactic acid and ethanol fermentation, which is of great significance for recycling resources, maintaining the ecological balance, optimizing the energy structure, alleviating the energy crisis, and promoting the implementation of the "Carbon Peaking and Carbon Neutrality" strategy. However, such an important metabolic process has not been involved in the current textbooks and teaching of biochemistry courses, making the teaching system incomplete. The anaerobic digestion process involves many reactions and complex metabolic pathways. In order to improve the students' understanding to this process, we created a full chart of the whole anaerobic digestion process based on systemic literature review and integrated it into the classroom teaching through the BOPPPS teaching mode. It was found that the classroom teaching assisted by this metabolic chart could help students establish the structural framework of the anaerobic digestion process and enrich the knowledge system of metabolism, achieving a good teaching effect. This paper introduces the content of the metabolic pathways of anaerobic digestion and the design of the teaching process, which would facilitate the teaching reforms and perfection of textbooks for related courses, such as Biochemistry, Environmental Engineering Microbiology and New Energy Engineering.

Engineering education is an important part of China's higher education. With the deepening of the connotation of new engineering talents training, it is timely to carry out the curriculum reform in all directions and improve the quality of engineering talents. In order to highlight the characteristics of fostering new engineering talents, specialized courses and practical courses are becoming the focus of curriculum teaching reform. However to this end, it is urgent to explore how to strengthen fostering talents with engineering characteristics in the professional foundation courses. Taking the biochemistry course as an example, problem-based learning teaching methods were employed, appropriate teaching cases were selected, scientific and technical problems based instructional designs were explored, and students were guided to condense, analyze and solve problems. This study aims to transform the learning attitude of students from "passive" to "active", enhance students' thinking skills, highlight the engineering application of science and technology, lay the foundation for continuous and even lifelong learning, and provide a reference for fostering talents under the new engineering background.

Biochemistry experiment is an experimental module associated with biochemistry curriculum. In the context of deepening the education reform on innovation & entrepreneurship, integrating the concept of innovation & entrepreneurship with the experimental course is an effective way for the biology discipline to foster professional talents with strong engineering ability and innovation & entrepreneurship ability. Outcome-based education (OBE) is a new concept for education. Guided by this concept, we encouraged students to propose and take part in research projects, redesigned the time frame for research project-based experiment teaching, and implemented a multi-dimensional evaluation system along the entire teaching process. Furthermore, we integrated the concept of innovation & entrepreneurship for training undergraduates during the teaching process of biochemistry experiment. These measures not only boosted the students' interest in research and innovation, but also guided the teachers to participate in the entire process, which helped improving the engineering ability and innovation & entrepreneurship ability of the students.

Biochemistry is an important fundamental course of biology related majors, and has the characteristics of speedy development, massive information, sound theoretical basis and feasible applicability. It is difficult for students to learn well in the process of teaching. In addition, the experimental course lacks integrity, comprehensiveness and design experiments. Under the guidance of outcome-based education (OBE) concept, we established a multi-dimensional teaching reform system through theoretically and practically introducing of various teaching methods, online courses, bilingual teaching, stronger practical teaching and optimized assessment mode. The teaching reform system could effectively allow students to change from "passive learning" to "active learning" through activating learning enthusiasm, resulting in cultivated innovation ability. This system could play very important role in promoting quality of talent training of colleges and universities.

biochemistry including prostate specific antigen (PSA) level was evaluated every 3 to 6 months after TRT, and radiological imaging was performed every 12 months. All patients had slight increases in PSA within the normal range and not indicative of biochemical recurrence. A sudden increase in PSA was observed in one patient, but it finally decreased. Aging male symptoms scale and various metabolic factors were improved by TRT in all of cases. Although adverse events included polycythemia in one patient, no patients experienced disease recurrence or progression during TRT. Our results suggest TRT for high risk-patients with HDR brachytherapy for prostate cancer may be beneficial and safe.]]>

BACKGROUND: Mesenchymal stromal cells (MSCs) have potent immunomodulatory and neuroprotective properties, and have been tested in neurodegenerative diseases resulting in meaningful clinical improvements. Regulatory guidelines specify the need to perform preclinical studies prior any clinical trial, including biodistribution assays and tumourigenesis exclusion. We conducted a preclinical study of human bone marrow MSCs (hBM-MSCs) injected by intrathecal route in Non-Obese Diabetic Severe Combined Immunodeficiency mice, to explore cellular biodistribution and toxicity as a privileged administration method for cell therapy in Friedreich's Ataxia. METHODS: For this purpose, 3 × 10⁵ cells were injected by intrathecal route in 12 animals (experimental group) and the same volume of culture media in 6 animals (control group). Blood samples were collected at 24 h (n = 9) or 4 months (n = 9) to assess toxicity, and nine organs were harvested for histology and safety studies. Genomic DNA was isolated from all tissues, and mouse GAPDH and human β2M and β-actin genes were amplified by qPCR to analyze hBM-MSCs biodistribution. RESULTS: There were no deaths nor acute or chronic toxicity. Hematology, biochemistry and body weight were in the range of normal values in all groups. At 24 h hBM-MSCs were detected in 4/6 spinal cords and 1/6 hearts, and at 4 months in 3/6 hearts and 1/6 brains of transplanted mice. No tumours were found. CONCLUSION: This study demonstrated that intrathecal injection of hBM-MSCs is safe, non toxic and do not produce tumors. These results provide further evidence that hBM-MSCs might be used in a clinical trial in patients with FRDA.
