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.

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.

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.

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.

Objective To study the change of serum procalcitonin(PCT) expression level and to investigate its clinical value for predicting the prognosis in the patients with severe acute pancreatitis (SAP) .Methods Totallay 48 inpatients with SAP in our hos‐pital from April 2012 to April 2014 were retrospectively analyzed .The PCT levels during different hospitalization period in the sur‐vial group and the death group were detected and analyzed .The scores of acute physiological and chronic health evaluation Ⅱ (A‐PACHE Ⅱ) were compared between these two groups .Results (1)The clinical characreristics of gender ,body temperature and WBC had no statistically significant differences beween the survival group and the death group (P>0 .05) ,but the PCT level had statistical differencet (P<0 .05) .(2)There was no statistically significant difference in the PCT level and APACHE Ⅱ score at ad‐mission between the two groups .In the later treatment process ,the PCT level and APACHE Ⅱ score in the survival group were progressively decreased ,while which in the death group were progressively inecreased (P<0 .05) .WT5HZ〗Conclusion PCT has an important clinical value in forcasting the prognosis of SAP .

Overview of the challenges faced by hospitals in China against prescription data leakage and the underlying causes is made in the paper,along with operable tactics proposed based on experience of data protection accumulated at the hospital.

Co-citations of foreign and domestic highly cited papers on drug target discovery were analyzed by clustering analysis using BICOMB2.01 and gCLUTO.Semantic analysis of the titles and abstracts in these highly cited papers and their important source literature showed that general trend, theoretical foundation, main methods and principal resources are the major hotspots of text mining in drug target discovery.

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.
