1.Investigation on pattern and methods of quality control for Chinese materia medica based on dao-di herbs and bioassay - bioassay for Coptis chinensis.
Acta Pharmaceutica Sinica 2011;46(5):568-72
Establishment of bioassay methods is the technical issues to be faced with in the bioassay of Chinese materia medica. Taking the bioassay of Coptis chinensis Franch. as an example, the establishment process and application of the bioassay methods (including bio-potency and bio-activity fingerprint) were explained from the aspects of methodology, principle of selection, experimental design, method confirmation and data analysis. The common technologies were extracted and formed with the above aspects, so as to provide technical support for constructing pattern and method of the quality control for Chinese materia medica based on the dao-di herbs and bioassay.
2.Changes of MB Isoenzyme of Creatine Kinase/Cardial Troponin I and Myocardial Pathological Damage of Rat with Endotoxemia at Early Stage
Journal of Applied Clinical Pediatrics 2006;0(18):-
Objective To explore the myocardial damage and the changes of MB isoenzyme of creatine kinase(CK-MB) and cardial troponin I(cTnI) of rat with endotoxemia at early stage.Methods Sixty SD rats were randomly divided into lipopolysaccharide(LPS) group(LPS group,n=48) and control group(n=12).Rats in LPS group were injected intraperitoneally with LPS(5 mg/kg) and then divided into 6 subgroups according sacrificed time after injection(0.5,1.0,2.0,3.0,12.0,24.0 h).CK-MB/ cTnI in blood was determined with chemiluminescent technique and myocardial pathological damage was observed under the light and transmission electron microscope.Control group was subjected to normal sodium and divided randomly into the same subgroups too.Results The rat diminished their action after beening injected endotoxin 15 minutes,and their reaction were slow.One hour later,they were short of action and reaction.Three hours later,they almost did not move at all,and the glossiness of their pelage were faint.Twenty-four hours later,their foodintake was diminished,their shout were weakened,and their response to stimulus were very thin,the glossiness of pelage were insufficient.Compared with control group,CK-MB increased significantly at 1.0,2.0,3.0,12.0,24.0 h(Pa
3.Advances in Studying Water Microbial Ecology by Molecular Biological Techniques
Microbiology 1992;0(04):-
Microbes are important composition of ecology system. Nowadays it's very important to study the microbial diversity and community structure, especially in water bioremediation by microbiological resources. Modern molecular biology techniques provide effective methods to study the microbial ecosystem in aqua. Several techniques were summarized, including 16S rDNA clone library, DGGE (Denaturing gradient gel electrophoresis), RFLP (Restriction Fragment Length Polymorphism) and T-RFLP (Terminal Restriction Fragment Length Polymorphism), while their application to analyze water microbial diversity were introduced.

Biological evaluation is a critical approach by which the quality standardization of traditional Chinese medicines can be linked to the clinical efficacy and safety, which has become an important aspect in the develop-ment of quality standardization of Chinese medicines. In this article, the necessity and feasibility of the biological e-valuation research were analyzed. Further, the main progress achieved as well as the major problems about the re-search and applications of the biological evaluation of traditional Chinese medicines were discussed, to bring forward a point for consideration or discussion.

Objective:
To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL.
Methods:
Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL.
Results:
A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β'= -0.179 ), diopter ( β'= 0.208 ), eyesight with glasses ( β'= -0.229 ) and anxiety ( β'= 0.439 ) were influencing factors for VRQL.
Conclusion
The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.
