Journal of Chongqing Medical University 1987;0(01):-
Objective:To observe the repairing effects and adverse action of bFGF polypeptide dressings to the superficial second degree burn wounds.Methods:30 superficial second degree burn patients were enrolled in this study.In a self-control study,the trial wounds(A) were applied with polypeptide dressings while the control wounds(B) with the saline gauze dressings to observe the promoting effect of bFGF on the wound healing and the possible adverse action.Results:The average healing time of the trial wounds was 12 days and was 3 days shorter than that of the control wounds.In comparison with control wounds,exudate and local inflammation were slighter on the trial wounds.The effective rate of bFGF polypeptide dressings reached 100%.Conclusion:bFGF polypeptide dressings can promote the healing of superficial second degeree burn wounds and shorten the healing time.This dressing is convenient,safe,non-irritative and has no obvious adverse actions.
2.Observation of the efficacy and safety of L-glutamine granules in treating severe burn patients
Journal of Chongqing Medical University 1986;0(04):-
Objective:To evaluate the clinical therapeutic effect of L-glutamine granules on intestinal damage of severe burn patients and the safety of the drug.Methods:Twenty-two severe burn patients were randomly divided into control group(C group, n =11) and L-glutamine treatment group ( n =11).GLN treatment group were given L-glutamine in a dose of 30g per day for 7 days and C group were given equal amount of placebo.The plasma L-glutamine concentration,the severity of intestinal mucosa damage, the level of plasma protein and parameters of immunological function were observed and the length of hospital stay was recorded.Results:After 7 days of taking L-glutamine orally,plasma L-glutamine concentration was significantly higher and the severity of intestinal mucosal damage were slighter in GLN treatment group than those in C group.The level of plasma protein and parameters of immunological function were higher in GLN treatment group than those in C group.In addition,the length of hospital stay was shorter in GLN treatment group than those in C group.Conclusion:Administration of L-glutamine can raise the plasma GLN level,abate the severity of intestinal damage obviously, maintain the barrier function of intestinal mucosa, enhance the immunological function, correct the negative nitrogen balance and promote the wound healing with no complications.

Chinese Journal of Marine Drugs 2001;0(05):-
Objective To investigate the optimal fermentation conditions for the production of antitumor active substances by marine bacteria HGX5 and preliminary study on their physicochemical properties.Methods Six factors including glucose,peptone,yeast extract,culture temperature,medium pH and agitation were investigated by Plackett-Burman Design, and the important factors including culture temperature,glucose and peptone were optimized by using response surface methodology(RSM).Results The optimal fermentation conditions were culture temperature 35℃,glucose 2.0g?L~(-1) and peptone 9.3g?L~(-1).The antitumor active substances showed better heat and pH stabilities via physicochemical experiments. Conclusion The adopted approach based on Plackett-Burman design and RSM was fit for the fermentation of this strain.
4.On Complexity of Syndromes from View of High Dimensions and High Ranks
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(02):-
The complexity of syndromes in traditional Chinese medicine comes from their high dimensions and high ranks.The high-dimensional characteristics of syndromes manifest in various and numerous space elements that constitute the clinical syndrome system.The elements can be grouped into at least nine categories including pathogenesis,pathological mechanism,pathological nature,pathological situation,pathological changes,and symptoms,relationships between evil QI and healthy QI,and body state.Furthermore,each element contains several sub-elements. The high-rank characteristics of syndromes manifest in the complex relationships among the elements.Dependency relationships among the elements of the lung diseases were extensively studied using Bayesian network technology.The result shows that the dependency relationships exhibit typically complex and nonlinear characteristics,linear and nonlinear interactions among the elements lead to a complex syndrome network architecture.
5.Investigation In postoperative quality of life of patients with gastric cancer and analysis of its influencing factors
Chinese Journal of Practical Nursing 2012;28(12):9-11
ObjectiveTo investigate and analyze the factors affecting the quality of life of patients with gastric cancer after surgery. Methods120 cases of gastric cancer patients undergoing resection of gastric cancer from March 2009 to March 2010 in our hospital were chosen as the research object.100 cases of non-cancer patients with similar general information and without factors affecting quality of life at the same period were chosen as the control group.Quality of Life Questionnaire of Stomach 22 (QLQ-STO22) were used to investigated the quality of life of patients in the two groups.The factors affecting the quality of life for patients with gastric cancer were analyzed.Countermeasures to increase the quality of life of cancer patients were explored according to factors affecting the quality of life. ResultsThe study showed that quality of life of gastric cancer patients was significantly lower than the control group.The differences were significant.Multiple linear regression analysis showed that gender,age,personality,education degree,family economic status,cancer disease were the main factors affecting their quality of life. ConclusionsIn clinical care of patients with gastric cancer,the medical staff should take appropriate psychological care and health education based on individual circumstances of patients,try to eliminate the adverse fractors of patients in psychology,cognition and thought in order to enhance the quality of life of patients after surgery.
6.Progress in synthetic biology of pinocembrin.
Chinese Journal of Biotechnology 2015;31(4):451-460
Pinocembrin, belonging to flavanons, was isolated from various plants. Pinocembrin has a variety of pharmacological activities, such as neuroprotective effect, antimicrobial activity, and antioxidant efficacy. Pinocembrin was approved as class I drugs to its phase II clinical trial by CFDA in 2009, mainly used for the treatment of ischemic stroke. As a promising compound, the manufacturing technologies of pinocembrin, including chemical synthesis, extraction from plant and synthetic biology, have attracted many attentions. Compared with the first two technologies, synthetic biology has many advantages, such as environment-friendly and low-cost. Construction of biosynthetic pathway in microorganism offers promising results for large scale pinocembrin production by fermentation after taking lots of effective strategies. This article reviews some of recent strategies in microorganisms to improve the yield, with focus on the selection of appropriate the key enzyme sources, the supply of precursors and cofactors by microorganisms, the choice of substance and the level of the key enzyme expression.
