AIM: To establish a method of determing prim-o-glucasylcimifugin,5-o-methylvisammiosode,gardenoside quantitatively in Huoxiang Gingwei Granules(Herba Pogostemonis,Fructus Gardeniae,Radix Saposhnikoviae,etc.). METHODS: Three components were determined by HPLC in the same chromatographic condition(Column: Shimadzu VP-ODS 250 mm?4.60 mm,5 ?m;mobile phase: acetonitrile-0.1% phosphoric acid gradient elution;flow rate: 1.0 mL/min: column temperature: at 30 ℃). RESULTS: Prim-o-glucasylcimifugin showed a good linear relationship at the range of 26.0-390 ng,r=(0.999 9),the average recovery was 101.7% and RSD was 1.1%.5-o-methylvisammiosode showed a good linear relationship at the range of 21.5-322.2 ng,r=(0.999 9),the average recovery was 101.9% and RSD was 1.1%.Gardenoside showed a good linear relationship at the range of 47.1-706.5 ng,r=(0.999 9),the average recovery was 101.6% and RSD was 1.1%.(CONCLUSION):() The established method can provide the content determination of 3 ingriedents at the same test condition and be used for the quality control of Huoxiang Qingwei Granules.

Objective To evaluate MRI in diagnosis and follow-up of Achilles tendon rupture. Methods From April 2003 to May 2005, 24 cases of closed Achilles tendon rupture were examined in our department with MRI. It was performed through sagittal T1WI, T2WI, GE-STIR and axial TME imaging. Four cases were followed up with MRI after 4 to 8 weeks. Results MRI could determinate the severity and exact location of Achilles tendon rupture by demonstrating signal changes of Achilles tendon. In this series, complete rupture of Achilles tendon mostly occurred at the median part, with augmentation and high signal on T2WI. MRI demonstrated high signal on T2WI in partial rupture of Achilles tendon. The signal intensity in the four cases followed up by MRI was shown to decrease. Conclusion MRI is a valuable tool for clinical diagnosis and follow-up of Achilles tendon, because it provides enough information through signal changes at the tendon.

Objective To investigate the relation between polymorphism of NOS3 G894T and susceptibility of cancer .Methods Literatures under the inclusion and exclusion criteria about relation between polymorphism of NOS 3 G894T and susceptibility of cancer were collected by computer -based retrieval and manual retrieval .The pools ORs with 95% CI were calculated to assess the association strength between polymorphism of NOS 3 G894T and cancer risk by Meta methods .Sensitivity and publication bias were evaluated .Results 19 literatures with 7679 cases of cancer and 8180 cases as control group were included .The pooled result indica-ted that no significant association between its polymorphism and cancer (ORT versus G=1 .030 ,95% CI=0 .964 -1 .101 ;ORTT versus GG=1 .056 ,95% CI=0 .895-1 .245 ;ORTG versus GG=1 .045 ,95% CI=0 .977-1 .119 ;ORTT/TG versus GG=1 .047 , 95% CI=0 .981-1 .117 ;ORTT versus TG/GG=1 .005 ,95% CI=0 .900-1 .123) .No significant association was observed in sub-group analysis based on ethnicity ,cancer type ,and source of control group .Conclusion There was no relationship between NOS3 G894T polymorphism and cancer susceptibility .

Medical imaging teaching depends on support from multimedia database which is constructed with image information provided by PACS/HIS ( Picture archiving and communication system/Hospital information system ).This paper evaluated construction,administration and application of the multimedia database,and illustrated the importance of PACS/HIS in construction of the database,as well as of the database in medical imaging teaching.

Objective:To investigate the role of anaphylatoxin C 5 a in patients with asthma .Methods:A prospective study was performed between September 2006 and February 2007.A total of 33 patients with acute exacerbation of asthma and 13 healthy subjects were recruited into the study .The patients with acute exacerbation of asthma were also studied when they returned to the remission state .Levels of lung function, levels of C5a in induced sputum and cell differential count in induced sputum were determined . Results:The level of C5 a in induced sputum was significantly higher in patients with acute exacerbation of asthma [0.85(0.68-2.13) μg/L] than that in patients with stable asthma [0.45(0.26-0.88)μg/L, Z=-2.193, P=0.013];Sputum C5a levels in stable asthma patients were significantly higher than those in healthy controls [0.14(0.06-0.45) μg/L, Z=-2.141, P=0.015].The level of C5a in patients with severe exacerbation [2.21(1.27 -9.0) μg/L] was significantly higher than those in patients with mild exacerbation [0.34(0.17-0.63) μg/L] and moderate exacerbation [0.85(0.55-1.67) μg/L,χ2 =12.330, P=0.001].The level of C5a in induced sputum was positively correlated with the number of total cells count (r=0.797, P=0.004), neutrophils (r=0.504, P=0.032) and macrophages ( r =0.424, P=0.036 ) in acute exacerbation of asthma .Conclusion: C5a levels in induced sputum could be identified as an important prognostic biomarker , which involved in asthma ’ s pathogenesis .

Objective To explore the significance of changes of matrix metalloproteinase-9 (MMP-9),interleukin-6 (IL-6),and tumor necrosis factor-alpha (TNF-oα) protein level in the cerebrospinal fluid (CSF) of children with viral encephalitis (VE).Methods The concentration of neuron-specific enolase (NSE),structural proteins 100B (S100B),and MMP-9,IL-6,TNF-α in the CSF of VE children were detected by an enzyme linked immunosorbent assay,and the correlations of them were analyzed.Results NSE,S100B,MMP-9,IL-6,TNF-α protein expression could be found significantly higher than those in the control group,and there were significant differences according to statistics expression trends(all P ＜0.05).The NSE protein expression was significantly positive related with S100B in the VE group (r =0.467,P =0.009),and the concentration was markedly negative related with the duration of viral encephalitis (r =-0.472,P =0.008).MMP-9,IL-6 protein expression were significantly positive related with NSE,S100B respectively (r =0.698,P =0.00 ; r =0.559,P =0.00 ; r =0.812,P =0.00 ; r =0.664,P =0.00).TNF-α protein expression was positive related with CSF S100B(r =0.363,P =0.049),but there was no correlation between TNF-α and NSE (r =0.245,P =0.193).Conclusions The neurons and the neuroglial cells are damaged in the viral encephalitis children.MMP-9,IL-6,TNF-α protein may participate in the pathological damage process of nerve cells in VE children in different degrees.

Objective To observe the therapeutic effect of resveratrol (Rsv) on psoriasis like skin damage induced by imiquimod (IMQ) and study its mechanism.Methods BALB/c mice were randomly divided into four groups:control group,Rsv group,model (IMQ) group and Rsv treatment (IMQ + Rsv) group with six mice in each group.Psoriasis like skin model induced by smearing IMQ in the mice's ear for 8 d,20 mg Rsv cream were gave at the same time for treatment.Observe erythema and psoriasis degree,and measure ear thickness with vemier caliper.HE staining was used to observe tissue change,real time quantitative PCR (qRT-PCR) was used to detect K17,IL-17A,IL-19 and IL-23 mRNA and Western blotting were used to detected K17 protein expression in tissues.Results Compared with the model group,mice erythema area and the thickness of epidermal scale decreased significantly in Rsv treatment group;HE staining results showed that,Rsv significantly reduced ear marginal tissue epidermal thickness,and diminished severity of the psoriasis-like skin inflammation.qRT-PCR and Western blotting confirmed a Rsv dependent decrease of in K17,IL-17A and IL-19 in mRNA level and protein levels of K17.Conclusion Rsv improves psoriasis like skin damage by down-regulating expression of Keratinl 7.
