2.Genome editing of industrial microorganism.
Chinese Journal of Biotechnology 2015;31(3):338-350
Genome editing is defined as highly-effective and precise modification of cellular genome in a large scale. In recent years, such genome-editing methods have been rapidly developed in the field of industrial strain improvement. The quickly-updating methods thoroughly change the old mode of inefficient genetic modification, which is "one modification, one selection marker, and one target site". Highly-effective modification mode in genome editing have been developed including simultaneous modification of multiplex genes, highly-effective insertion, replacement, and deletion of target genes in the genome scale, cut-paste of a large DNA fragment. These new tools for microbial genome editing will certainly be applied widely, and increase the efficiency of industrial strain improvement, and promote the revolution of traditional fermentation industry and rapid development of novel industrial biotechnology like production of biofuel and biomaterial. The technological principle of these genome-editing methods and their applications were summarized in this review, which can benefit engineering and construction of industrial microorganism.

3.cAMP signaling pathway and multiple myeloma
Journal of International Oncology 2014;41(5):368-370
The clonal proliferations of multiple myeloma cells consist of several signaling pathways.It has been shown that cyclic adenosine monophosphate (cAMP) signaling pathway,an important intra-cellular messenger delivery system,is related to abnormal proliferation and apoptosis of malignant lymphoid cells including myeloma cells.Manipulating the cAMP signaling pathway could induce cell cycle arrest and apoptosis of various malignant lymphoid cells including myeloma cells,which involve mitochondrial-dependent apoptosis and cAMP-modulated changes of intra-cellular mediators.In-depth researches and analysis of cAMP-induced apoptosis in myeloma cells would provide potential targets and possible therapeutic means in the treatment of multiple myeloma.
4.Prevalence and Analyses of the Changing Etiology of Hand, Foot and Mouth Disease in China.
Chinese Journal of Virology 2015;31(5):554-559
Hand, foot, and mouth disease (HFMD) is a viral infectious disease regarded to be a public-health problem worldwide. Since the 1990s, HFMD began to spread in the Asia-Pacific region (especially in South-East Asia). HFMD outbreaks have occurred in mainland China frequently since 2008, and the morbidity and mortality of HFMD has continued to increase in recent years. In mainland China, enterovirus A serotype enterovirus A71 (EV-A71) and coxsackievirus A16 (CVA16) have been the major pathogens of HFMD during these years. However, the etiological spectrum of HFMD changes with time. This review focuses mainly on the etiological spectrum of HFMD and changes in epidemic patterns in mainland China.

5.EFFECTS OF HIGH FREQUENCY JET VENTILATION ON RESUSCITATION OF BRAIN FUNCTIONAL FAILURE IN CATS
Medical Journal of Chinese People's Liberation Army 1981;0(04):-
The effects of high frequency jet ventilation(HFJV) on brain resuscitation had been investigated in 28 cats in which simple brain functional failure was produced by occlusion of both carotid and both vertebral arteries. The results suggested that HFJV could improve endurance of cats when subjected to brain ischemia, raise the survival rate of cats with reversible brain functional failure, and prolong the survival time of cats with permernent brain functional failure. The mechanisms of how HFJ would exert beneficial effect on brain resuscitation was discussed.
7.Molecular markers of autophagy.
Acta Pharmaceutica Sinica 2016;51(1):33-38
Autophagy is a physiological process which delivers the mutant cytoplasmic proteins and dysfunctional subcellular organs into lysosomes for degradation to generate fuel in the deficiency conditions. It is mainly classified into macroautophagy, microautophagy and chaperon-mediated autophagy (CMA), as well as the selective autophagy such as mitophagy and aggrephagy. This review mainly introduces the key molecular markers of macroautophagy, CMA and mitophagy.

Chinese Journal of Pathophysiology 2017;33(1):92-97
AIM:To observe the effects of edaravone on high glucose-induced apoptosis of SH-SY5Y cells and its potential mechanism .METHODS:The SH-SY5Y cells were cultured in the DMEM medium with 100 mmol/L glucose and 100μmol/L edaravone for 24 h.The viability of the SH-SY5Y cells was detected by MTT assay .The levels of ROS in the cells were determined by DCFH-DA fluorescent probing .The apoptotic rates of the cells were analyzed by flow cytome-try.The protein expression of Bax and Bcl-2 in the cells were detected by Western blot .The expression levels of micro-RNA-25 (miR-25) were determined by real-time PCR.To further clarify the target sites of edaravone on inhibiting apopto-sis induced by high glucose , miR-25 inhibitor was applied to the SH-SY5Y cells and the activity of caspase-3 was meas-ured.RESULTS:Compared with control group , the cell viability was decreased significantly in model group , and the ROS level was increased significantly .The protein expression of Bax was up-regulated significantly , while the expression levels of Bcl-2 and miR-25 were significantly down-regulated .Compared with model group , the cell viability was increased signifi-cantly in edaravone group .The ROS level was decreased significantly .Meanwhile, the expression of Bax was down-regula-ted, while the expression of Bcl-2 and miR-25 was up-regulated with statistical significance .The caspase-3 activity of the cells incubated with 100 mmol/L glucose and miR-25 inhibitor was increased .However, no alteration of caspase-3 activity with edaravone added simultaneously was observed .CONCLUSION: Edaravone inhibits the apoptosis of SH-SY5Y cells induced by high glucose with the potential target site of miR-25.
9.Mechanisms of nuclear receptors in gallstone formation
International Journal of Surgery 2016;43(7):499-502
Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.
