1.Advances in protein energy malnutrition in patients with chronic kidney disease
Chinese Journal of Clinical Nutrition 2013;21(1):30-34
The incidence of malnutrition among patients with chronic kidney disease (CKD) constantly increases despite the development of health care and dialysis techniques.New nutritional targets for CKD patients upon maintenance treatment have been developed.Before dialysis,evidences have shown that a long-term nutritional care plan,with a control of protein intake,can effectively correct metabolic disorders including proteinuria and acidosis.During the maintenance dialysis,the optimal protein and energy intakes have been recently challenged.The new classification of nutritional disorders in CKD patients may help the easily identification of protein-energy wasting.
2.Expression and location of IL-2/IFN-? fusion protein in colorectal tumor cell lines
Chinese Journal of Practical Internal Medicine 2006;0(18):-
Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.
3.Glucose fluctuation and intervention in its clinical significance
Journal of Medical Postgraduates 2003;0(07):-
The initiation and development of diabetic chronic complications is associated not only with the level of blood glucose,but also with the glucose fluctuation.The damage in large artery and microvessel may be caused by glucose fluctuation.There are two causes which induce glucose fluctuation in clinical:one is postprandial hyperglyceamia with not well controlled,the other is hypoglycemia causes by unsuitable therapy.A lot of effective new types of substances were applicated in clinical,such as ?-glucosidase inhibitor,glinide-insulin secretagogus,fast-acting and long-acting insulin analogues.With these new powerful tools,there is possibility to treat diabetes more correctly and safely,and control the blood glucose in a stable and good level.

8.Features and Translation of Medical English Words
Chinese Journal of Medical Education Research 2003;0(04):-
This paper gives a comprehensive analysis of the origin,formation as well as feature of medical English words in the hope of more accurate understanding and expression in their translation.
9.Principles of selecting words and making sentences in medical English writing
Chinese Journal of Medical Education Research 2012;11(7):750-753
Medical English writing presents specific principles of selecting words and making sentences.Word selecting requires brevity,necessity,and clarity,while sentence making demands proper length,expressive verb,and impressive subject.Understanding these principles is of great help to Chinese medical writers.
10.Stem cells in cartilage tissue engineering and influential factors
Chinese Journal of Tissue Engineering Research 2013;(46):8116-8121
BACKGROUND:A variety of stem cells as seed cells for cartilage tissue engineering have been extensively studied.
OBJECTIVE:To analyze the biological characteristics of different kinds of stem cells and their application in cartilage tissue engineering.
METHODS:By retrieving recent studies on sources of stem cells and influential factors in cartilage tissue engineering, the authors focused on optimization of harvesting stem cells from different sources in bone tissue engineering, problems, and factors that affect cellgrowth, differentiation, reproduction and metabolism, which provide a theoretical basis for tissue-engineered cartilage repair.
RESULTS AND CONCLUSION:A large number of experimental studies have confirmed that exogenous stem cells can be used as seed cells for cartilage tissue engineering. Influential factors relative to cartilage tissue engineering construction using seed cells include growth factors, cellscaffold, cellseeding density, oxygen concentration, stress and micro-gravity. However, tissue-engineered cartilage is stil in the stage of laboratory research, and stem cells for cartilage tissue engineering involves many issues, such as stem celltransformation, in vitro culture of stem cells, how to prolong the survival of cells, reduce cellantigenicity and enhance the host’s immune tolerance, which are yet to be resolved.
