Pesticides, especially chemistry pesticides with high toxicity, high residue, and difficult degradation are a kind of important environment pollutants and pesticide degradation by microorganisms is one of the powerful means to treat pesticide pollution. Many researchers conducted lots of studies on it. Types of pesticide degraders, construction of genetically engineered microorganisms, degrading mechanisms, degradation characteristics, influencing factors, applying effect and so on were summarized in this article. The research trend of degradation of pesticides by microorganisms and problems to be solved were also put forward.

Objective To observe the effects of standardized three stage rehabilitation treatment on the neu- rological deficit scores (NDS) and ADL performance of ischemic stroke patients.Methods A total of 164 ischemic stroke patients were recruited and randomly divided into a rehabilitation group and a control group.The neurological function and ADL performance of the patients were assessed by using NDS and Modified Barthcl Index (MBI) at the admission,at the end of 1st,3rd and 6th months post stroke.Results No significant differences were found be- tween the rehabilitative and the control groups with regard to NDS and MBI at admission.The NDS demonstrated a decreasing tendency,while the MBI score an increasing tendency in both groups.In the control group,significant difference of NDS was found between admission and the end of 1st month as well as between the end of the 1 st and the 3rd months.In rehabilitation group,significant difference was revealed between all the time points with regard to NDS and MBI scores.At the end of the 1st,3rd and 6th months,the MBI scores of the rehabilitation group were signifi- cantly higher than those of the control group,indicating that the ADL performance of those treated with standardized three-stage rehabilitation protocol was improved quicker than those without the protocol.Conclusion Standardized three-stage rehabilitation treatment could improve the neurological function and ADL performance of the ischemic stroke patients.

The high and continuing soaring incidence of diabetes may become a huge obstacle to China's development. The antidiabetic drug development is one way to solve the problem. Animal model is a powerful tool for drug development. This paper compares and analyzes the three kinds of animal models for antidiabetic drug development in replicating principle, methods and characteristic, then summarized the application in the research of traditional Chinese medicine. At the same time, the analysis of the market, application and clinical advantages of hypoglycemic medicine from traditional Chinese medicine, is given in this paper, based on the literature analysis. From the point of the clinic advantage embodiment and new drug development, this paper will provide advisory and assistance support for the anti-diabetic fighting with traditional Chinese medicine.

24 cases of renal failure induced by chemotherapy were treated with Wuling powder plus additives.Theresult of clinical amelioration was 87.5%.with a to-tal effective yielded marked actions of promoting ap-petite in animals,lowering serum urea nitrogen,cre-atinine,2 microglobulin.It also decreased the inhibi-tion of PDD on the enzyme activity of renal Na~+—K~+ATP.Microscopic exam revealed the pathological le-sion of kidney to be milder in the tested group.

Objective To explore dynamic response of serum lipids and relationship with body mass index(BMI)after fat meal in obese children and adolescents. Methods The subjects were 31 obese children and adolescents (BMI ≥ 25 kg/m2) and 30 controls (BMI

OBJECTIVEIn this study, we aimed to investigate the expressions of adhesion molecules on human bronchial epithelial cells and neutrophils in co-culture system, assess the effects of puerarin on suppressing these adhesion molecules expressions, and explore the roles of two crucial signal-transduction elements p38 mitogen-activated protein kinase (p38 MAPK) and nuclear factor kappa B (NF-κB) in modulating adhesion molecules expressions.

METHODSNeutrophils and BEAS-2B cells (one human bronchial epithelial cell line) were co-cultured, and adhesion molecules expressions on cell surface were detected using flow cytometry. The mRNA levels of adhesion molecules were assessed by real-time quantitative polymerase chain reaction (real-time qPCR). Phosphorylated p38 MAPK and inhibitor κB were analyzed by Western blot.

RESULTSIn co-culture system, adhesion molecules expressions on BEAS-2B cells and neutrophils were enhanced significantly (P<0.05). Correspondingly, the mRNA levels of adhesion molecules were also increased greatly. Moreover, the pretreatment of peurarin obviously suppressed adhesion molecules expressions on cell surface. Furthermore, phosphorylated p38 MAPK and inhibitor κB in BEAS-2B cells and neutrophils were elevated in co-culture system, but decreased significantly after upon the treatment of peurarin (P<0.05).

CONCLUSIONSCoculture boosted the interactions between human bronchial epithelial cells and neutrophils mimicking airway inflflammation, whereas peurarin decreased the expression of adhesion molecules on cell surface by suppressing the activities of p38 MAPK and NF-κB pathways, and exhibiting its anti-inflflammation activity.
