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.

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.

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.

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.

[Objective] To investigate the effect of Zhutan Tongluo Tang on the expression of interleukin-1?(IL-1?) and interleukin-6(IL-6) and changes of nerve function in acute cerebral hemorrhage rat.[Methods] Rats were randomly divided into four groups: normal control group(N),sham-operative group(K),model group(C) and Zhutan Tongluo Tang group(Z),Collagenase was used to establish rat model of intracerebral hemorrhage,each group of animal nerve function damage was evaluated and graded after operation,ELISA method was used to test the expression of IL-1? and IL-6 in blood.[Results] 1.Score of nerve function: there was no significant difference between Z and C group in the first 1,2d.There was difference on 3d(P

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 .

Methods:A TLC method was used to identi-fy five components including Asari Radix Et Rhizoma, Schisandrae Chinensis Fructus, Fritillariae Cirrhosae Bulbus, Platycodonis Radix and Citri Exocarpium Rubrum in the capsules. An HPLC method was used to determine the content of Citri Exocarpium Rubrum. Re-sults:The TLC identification method for Asari Radix Et Rhizoma, Schisandrae Chinensis Fructus, Fritillariae Cirrhosae Bulbus, Platyc-odonis Radix and Citri Exocarpium Rubrum was established without any interference. The HPLC method for the determination of Citri Exocarpium Rubrum was established, and the linear concentration of hesperidin was 3.03-302.80 μg·ml-1(r=0.999 9), and the average recovery was 99. 80%(RSD=0. 49%,n=9). Conclusion:The new quality standard is simple and accurate, which can effec-tively control the quality of the preparation.
