Objective To observe and analyze the MRI manifestations of Klippel-Trenaunay syndrome(KTS).Methods Thirty-one cases with diagnosed KTS underwent MRI on a 1.5 T MR system. MRI,MR venography(MRV),MR angiography(MRA)and X-ray venography(XRV)were performed.The pathological changes of the limbs and their veins were observed.Results MRI found soft tissue hemangiomas in 12 cases,soft tissue swelling of the extremities in 27 cases,superficial varicosities in 21 cases,and malformation of the veins in 27 cases.In twenty patients who underwent both MRV and XRV, superficial varicosities in 17 cases and persistent sciatic veins in 11 cases were found with both techniques. The increase of tributary veins was found in 10 cases with XRV,while found in 15 cases with MRV.The erratic venous course was found in 4 cases with MRV.The abnormalities of deep veins were found in 8 cases with MRV,while found in 7 cases with XRV.Conclusion MRI is an efficient and reliable imaging method for diagnosis of KTS.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

Objective To perform a biomechanical study on and compare the stability of internal fixation with closed Kirschner wire in different spots from the epicondylus medialis to sulcus nervi ulnaris and epicondylus lateralis of humerus in the treatment of GartlandⅢsupracondylar fractures of humerus in children in order to provide basis for avoiding cubitus varus in clinic.Methods Twenty models of su- pracondylar fractures were made from ten humerus samples,then divided into two groups(group A and group B).They were fixed with closed Kirschner'wires.Ulnar Kirschner wire varied.In group A five spots were selected averagely from the epicondylus medialis to the sulcus nervi ulnaris.Kirschner wires entered from one of the five spots into another spot of humerus.In group B Kirschner wires entered defferent spots of humerus from the central spot of sulcus nervi ulnaris.Biomechanical tests were carried out,such as axial load,axial displacement,stress intensity,axial rigidity and anti-twisty ability.Forty-six children with Gart- landⅢsupracondylar fracture of humerus were treated and followed up for more than one year.Results In beth groups,with the angle of Kirschner wires and fracture side increasing,the strain and the vertical displacement decreased,the stress intensity and the axial rigidity increased,and the anti-twists ability was enhanced.There was statistic difference(P＜0.05).The follow-up of the 46 patients showed the elbow joint function recovered well with no cubitus varus malformation.Conclusion Internal fixation with closed Kirschner wires in sulcus nervi ulnaris from the epicondylus medialis and the epicondylns lateralis of humerus for GartlandⅢsupracondylar fracture of humerus in children has the advantages of enhancing bio- mechanical stability,effective prevention of secondary replacement of outlying black of the fracture and a- voidance of cubitus varus.It can be widely used clinically.

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.

METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.

RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).

CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.001). The results of the experiment proved that different β-AS genotypes at 94 bp site from different regions may be one of the important reasons to result in the genuineness of Glycyrrhiza uralensis.

Glycyrrhiza uralensis Fisch. ex DC is widely used in traditional Chinese medicine (TCM). Among its various active components, glycyrrhizic acid is believed to be the marker component. Squalene synthase (SQS) and beta-amyrin synthase (beta-AS) are key enzymes in the biosynthetic pathway of glycyrrhizic acid in G uralensis. To reveal the effects of co-expression of SQS1 and beta-AS genes on this pathway, 7 yeast expression vectors harboring different SQS1 variants and beta-AS were constructed and expressed in Saccharomyces cerevisiae as fusion proteins. TLC and GC-MS results showed that co-expression of SQS1 and beta-AS enhanced the accumulation of beta-amyrin. The effects of SQS12 were more obvious than the other two SQS1 variants. This study is significant for further investigations concerned with exploring the biosynthesis of glycyrrhizic acid in vitro and strengthening the efficacy of G. uralensis by means of increasing the content of glycyrrhizic acid.
