The difference between three representative components of total salvianolic acids in pharmacodynamic activity were compared by three different pharmacological experiments: HUVECs oxidative damage experiment, 4 items of blood coagulation in vitro experiment in rabbits and experimental myocardial ischemia in rats. And the effects of contribution rate of each component were calculated by multi index comprehensive evaluation method based on CRITIC weights. The contribution rates of salvianolic acid B, rosmarinic acid and Danshensu were 28.85%, 30.11%, 41.04%. Apparent oil/water partition coefficient of each representative components of total salvianolic acids in n-octyl alcohol-buffer was tested and the total salvianolic acid components were characterized based on a combination of the approach of self-defined weighting coefficient with effects of contribution rate. Apparent oil/water partition coefficient of total salvianolic acids was 0.32, 1.06, 0.89, 0.98, 0.90, 0.13, 0.02, 0.20, 0.56 when in octanol-water/pH 1.2 dilute hydrochloric acid solution/ pH 2.0, 2.5, 5.0, 5.8, 6.8, 7.4, 7.8 phosphate buffer solution. It provides a certain reference for the characterization of components.

OBJECTIVETo observe the changes of behavior and amino acids in brain tissue of rats with adjuvant arthritis, and effects of Xinfeng Capsule (XFC) on them.

METHODSAA model was induced by complete Freund's adjuvant in rats. Five groups including the normal control group, the model group, the XFC group, the methotrexate (MTX) group and the Tripterygium wilfordii polysaccharide (TPT) group were set up. The changes of behavior, amino acids in brain tissue, swelling degree of joints, and arthritis index (AI) were observed and the correlation analysis on these indexes was performed.

RESULTSCompared with those in the normal control, the frequency of independent activity obviously decreased in the model rats, accompanied with increased number of step-down errors, shortened step down latency (SDL) and prolonged escape latency (EL), also the level of gamma-aminobutyric acid (GABA) in brain tissue elevated and glutamic acid (GLU)/GABA reduced (P <0.05). Compared with those in the model group, all the above indexes were improved significantly in the XFC group after treatment (P <0.05), while they changed insignificantly in the MTX and TPT groups (P> 0.05), the degree of joint swelling and AI were obviously lower in the 3 treated groups (P< 0.05). Correlation analysis showed the frequency of independent activity and SDL were negatively correlated to the swelling degree of joint, and levels of AI, glycine (GLY) and GABA respectively, but positively correlated with GLU/GABA (P<0.05); while EL and number of step-down errors were positively correlated to AI, GLY and GABA respectively, but negatively correlated to GLU/GABA (P < 0.05).

CONCLUSIONImmune stress could lead to the changes of rat behavior and amino acids in brain tissue. XFC treatment could improve the behavior of AA rats through regulating the levels of amino acids in brain tissue.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

Objective To study the effect of platelet-derived growth factor(PDGF)and lysosomes on lung injury in macaque with early-phase endotoxie shock.Method Eleven macaques were randomly divided into two groups,namely,control group(Co group,n=5)iand endotoxic group(En group,n=6).The macaque of the Co group injected with 1 ml/kg normal saline and the macque of the En group received a dose of 2.8 mg/kg Lipopolysaccharides(LPS)i.v.The blood gas was detected at 120 minutes after LPS challenging. Uhrastructure,cytochemistry of acid phosphatase(ACPase)detection by electronic microscopy and immunohistochemical assay of PDGF were completed in hmgs of all the macaque .Results Administration of LPS did not change the parameters of gas exchange,namely,PaO_2,PaO_2/Fi and PaCO_2.In the early phase,of endotoxic shock,ACPase activity products increased and lysosome destroyed in the alveolar cells.The pathologic changes of alveolus,such as degeneration of vessel endothelium,injury of alveolar epithelium and damage of basement membrane,and transudation of blood component were observed by electron microscopy in the En group. However,no pathological changes were found in the control group.By immunohistochemical staining,PDGF on alveolar wall in the En animals was observed,whereas no PDGF protein in the Co macaques was noticed. Conclusions Administration of LPS induced the expression of PDGF in the alveolar wall and lysosome injury in the alveolar cells,as a result of alveolar damage in early-phase endotoxin shock.In the meantime,the parameters of gas exchanges did not change.The PDGF may play an important role in the pathogenesis of lung during the early-phase of endotoxin shock.
