1.Analysis of heart rate variability in the patients with malignant tumor of different phases
Fudan University Journal of Medical Sciences 2009;36(4):413-416
Objective To evaluate the clinical practical value of the heart rate viability test in the patients with malignant tumor during their therapies. Methods Totally 187 cases were analyzed and were divided into three different groups, which included 90 malignant tumor patients before therapy, 45 patients with chemotherapy and 52 non-malignant tumor cases (control group). We compared four HRV indexes(ASDNN5,SDANNS, SDNN and RMSSD) of the patients between the different groups as well as inside each group. Results There were statistical significances in the indexes of ASDNN5, SDANN5 and SDNN of patients at different stages before therapy, the three indexes of the stage Ⅲ group were lower than those of the stage Ⅰ group and the control group as well. The three indexes of the stage Ⅳ group compared with the stage Ⅰ group or the control group (P<0.05) were lower either. There was also statistical significances in SDNN between the stage Ⅲ and the stage Ⅱ of the before-therapy group (P< 0. 05). The indexes of SDANN5 and SDNN of the stage Ⅳ in the chemotherapy group were lower than those of the same stage in the before-therapy group(P<0.05). Conclusions The later the stage of malignant tumor patients is, the more the index of HRV declines. Chemotherapy may affect autonomic nerve function of stage Ⅳ patients with malignant tumor and decrease their HRV.

4.Epithelial cells-stem cells interactions in wound healing
Chinese Journal of Tissue Engineering Research 2010;14(6):1092-1096
BACKGROUND: At the process of wound healing, the epithelial cells and epidermal stem cells interactions is complicated which promoting the mechanisms of wound healing. The abnormities of any fine phase can be result in delayed healing or scarring. OBJECTIVE: To summarize the characterization of epithelial cells and epidermal stem cells and their interaction in wound healing so that we can recognize the mechanisms of scarring from histomorphology, biochemistry and molecular variations. METHODS: A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on epithelial cell and epidermal stem cells interactions in wound healing and results in scarring published from 1974 to 2009 with the key words of "epithelial cells, epithelial stem cells, wound healing, keratinocytes, fibroblasts, hypertrophic scar, keloid" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) published between 1999 and 2009 with the same key words in Chinese. A total of 43 articles were collected about the cell structure (3 articles), the cell interactions in wound healing and scarring (16 articles), the relevant on epithelial stem cells (24 articles).RESULTS AND CONCLUSION: The effect of different cells in epithelial tissue is known to all. The keratinocytes and fibroblasts had been on studying frequently, and their closely correlated to scarring. At present, the epithelial stem cells has been confirmed, but the relevant on their location, quality and specific epidermal markers are unclear which need to study and explore. With the rapidly development of science and technology, we maybe control the expression of cells by genic regulation not only culture the cells of our need but to prevent the scarring.
6.Evidence-based medicine in stomatology.
West China Journal of Stomatology 2014;32(6):533-536
Evidence-based medicine (EBM) has rapidly developed in recent years and is currently a hotspot in international medicine. The guiding principle behind EBM is that any medical decision should be determined based on objective clinical and scientific evidence, doctor's professional skills and experience, and patient's needs and desires. This paper introduces the concept and practice of EBM and explains how it can be used to solve the issues in stomatology.

9.Bt transgenic crops for insect-resistance and modification of Bt protein and utilization of stacking strategy.
Chinese Journal of Biotechnology 2015;31(1):53-64
Insecticidal protein genes from Bacillus thuringiensis are currently the most widely used insect-resistant genes. They have been transferred to many crops for breeding and production. Among them, cotton, maize, potato and other insect-resistant crops are commercialized, creating considerable economic benefit. In this review, we summarized advances in identifying functional genes and transgenic crops for insect resistance, compared different strategies for enhancing vigor of insecticidal protein and utilizing gene stacking as well as listing valuable groups of stacked genes. In addition, the methods for multiple gene transformation was discussed.

Chinese Journal of Dermatology 2009;42(9):610-612
5). Conclusions Q-switched alexandrite laser is an effective approach to the treatment of care -au-lait spots, and its efficacy can be predicted according to different factors that concern.
