With the progress and development of science and technology, biomedical technology has been widely used in traditional Chinese medicine (TCM) research. However, TCM and Western medicine developed and came into being at different times and from different cultural backgrounds. Their targets are to study and explore the objective laws of human life activities from different angles and by different means. To study and evaluate TCM simply by the diagnosis and treatment standards of Western medicine cannot truly reflect the characteristics of TCM. Lots of clinical phenomena in the diagnosis and treatment in TCM cannot be revealed scientifically. It might be a significant pattern to combine the study of TCM with Western medicine, based on double-screening model of combining disease with syndrome types, following up evidence-based medical research steps, and making use of systematic review and data mining to analyze the inherent laws of TCM symptoms.

According to content of ‘lipid metabolism’,we crafted a effective case for problem based learning (PBL) and practiced it in biochemistry course.In group discussion,students participated in discussion with great enthusiasm and initiative.During the discussion,students got a better understanding about lipid metabolism and clinical application of the knowledge.As teachers,we maily guided students during PBL,and at the same time,we also summed up the experience and explored how PBL be implemented for freshmen and sophomores who lack clinical practice.

Objective To evaluate an immunochemiluminescence assay for human plasma B-type natriuretic peptide(BNP),and to investigate the reference interval of BNP in healthy Chinese.Methods EDTA anti-coagulant plasmas from 421 healthy volunteers(202 men and 219 women) were included.BNP was measured with Triage BNP kit developed by Biosite on the Beckman Coulter Access II.Referring to the EP documents,a series of tests were designed to investigate the assay′s linearity,detection limit,sensitivity,precision,interference factors,and BNP′s stability under different storage conditions.Results The assay had a linearity of 15~5 040 ng/L,and the detection limit was 9.2 ng/L.The concentration at 10% of CV was 30 ng/L.There was no obvious interference in the assay when bilirubin was 75 years old persons was 100.7 ng/L.Conclusion The immunochemiluminescence assay for human BNP is highly sensitive.The characteristic of its wide detection linearity,precision,and anti-interference ability meets the clinical requirement.We recommend that the 97.5% percentile be a reference interval;when the age is 55 years old,the value is

Objective To investigate the effects of transforming growth factorβ1(TGFβ1)and β3 (TGFβ3)gene transfer on MMP-2,MMP-9 and TIMP-1 expression in hepatic stellate cells(HSC-T6).Methods TGFβ1 and TGFβ3 expression plagmids were constructed.The recombinant expression plasmid pcDNA3.1(+)-=TGFβ1 and pcDNA3.1(+).TGFβ3 were transfected or cotransfected into HSC-T6.At 24,48 and 72 h after transfection,the expression of MMP-2,MMP-9 and TIMP-1 mRNA were detected by real-time quantitative PCR,and the expression of MMP-2,MMP-9 and TIMP-1 protein were detected by Western blot.The recombinant expression plasmid pcDNA3.1(+).TGFβ1 was transfected into HSC-T6,and positive clones were selected by G418.The positive clones were transfected by the recombinant expression plasmid pcDNA3.1(+).TGFβ1,and the expression of MMP-2,MMP-9 and TIMP-1 were detected at 48 h after transfection.Results After transfection with peDNA3.1-TGFβ1,MMP-2 and TIMP-1 increaged remarkably in HSC-T6 cells(P＜0.05),but MMP-9 remained at the sanle level;After transfection with pcDNA3.1-TGFβ3,expression levels of MMP-2,MMP-9 and TIMP-1 mRNA were not changed,but TIMP-1 protein increased remarkably(P＜0.05);in cotransfection group,the expression of MMP-2 was higher than that in the blank and the control groups(P＜0.05),but MMP-9 level was not changed and TIMP-1was decreased compared with that in the TGF-β1 transfection group(P＜0.05).After TGFβ3was transfected into positive clones,the change of MMP-2 wag not significant(P＞0.05).but MMP-9 increaged and TIMP-1 decreased significantly at 48 h after transfection(P＜0.05).Conclusions TGFB3 may inhibit liver fibrosis by increase the activity of MMP-2 and MMP-9,and decrease the activity of TIMP-1.

Objective To study the mechanism of the protective effect of lycium barbarum polysaccharide on light aging resistance rats by using the metabolic profile and metabolic target analysis technique.Methods Ultraviolet irradiation induced Wistar rats were induced to produce skin photo aging model and 24 rats were randomly divided into three groups, including control goup, model group, Lycium barbarum polysaccharide group (LBP). After modeling for 24 hours, LBP group was conducted with Lycium barbarum polysaccharide solution of 10 mg/kg. Control group and model group were given same volume of stroke-physiological saline solution for 14 days. The biochemical indexes such as rat serum antioxidant activity of related substances and MDA were measured in model group and drug group; the urine metabolomics study was also investigated for the mechanism of lycium barbarum polysaccharide against light aging band.Results Compared with the model group, the LBP group rats total superoxide dismutase activity (301.51 ± 42.56 U/mgvs.93.41 ± 56.31 U/mg), hydroxyproline (8.91 ± 5.78μg/mgvs.4.74 ± 1.54μg/mg) content significantly increased (P<0.05), but the malondialdehyde (8.54 ± 6.41 nmol/mgvs.21.31 ± 6.58 nmol/mg) decreased without any statistics difference (P<0.05). The urine metabonomics results showed that LBP could regulate the skin photoaging of multiple metabolic pathways and key metabolic enzymes in the process, such as peanut four acid, tyrosine, taurine, citric acid and hippuric acid, L-cysteine, inositol, threonine etc.Conclusions In the process of skin photoaging in rats, multiple metabolic pathways in vivo were disordered, and Lycium barbarum polysaccharide could play a protective role by regulating the key metabolic enzymes in the network.

Objective Gas chromatography-mass spectrometer (GC-MS) technology combined with Heuristic evolving latent projections (HELP) method were used to qualitatively analyze the volatile oil of fructus lycii (Lycium barbarumL.)Methods With the best temperature-programmed chromatographic condition, overlapping peaks among the total ion chromatogram were separated. Then an automatic mass spectral deconvolution and identification system (AMDIS) was used to identify volatile components comprehensively. Finally, the pure chromatographic peaks were matched with NIST 05a mass spectra library for giving the precise qualitative result. Results Totally, 29 compounds in fructus lycii (Lycium barbarum L.) were identified accurately.Conclusions Compared with the traditional qualitative analysis method, the new established method which GC-MS technology combined with HELP could get tremendous advantages. It not merely enhanced the accuracy of identification but also solved the bottleneck of handling the inseverable compounds.
