BACKGROUND: Low-frequency ultrasound combined with Tongluo Zhitong herbs can effectively relieve pain and improve joint function of patients with osteoarthritis, but the underlying mechanisms are still unclear.OBJECTIVE: To investigate the effects of low-frequency ultrasound combined with Tongluo Zhitong herbs on urokinase-type plasminogen activator (uPA) and inflammatory cytokines of osteoarthritis rabbits and the related mechanisms.METHODS: Forty rabbits were randomly divided into four groups: normal, model, control, and experimental groups. The normal group was treated with normal feeding, not for any processing. For the other three groups, papain was injected into the rabbit knee articular cavity to establish osteoarthritis models. One week later, the experimental group was treated with low frequency ultrasound combined with Tongluo Zhitong herbs for 3 weeks, the control group treated with the same volume of normal saline, and the model group received no intervention. The levels of inflammatory cytokines in the serum and synovial fluid were measured, the histological changes of synovial tissues and articular cartilage were evaluated using Mankin's score, and the expression levels of uPA and its receptor were determined by western blot assay.RESULTS AND CONCLUSION: The levels of inflammatory cytokines in the model group were significantly higher than those in the normal and experimental groups (P < 0.05). The Mankin's scores of synovial tissue in the experimental group were significantly lower than those in the model and control groups (P < 0.05), while Mankin's scores of the cartilage tissue had no significant difference between the experimental and model groups (P > 0.05). Compared with the model group, in the experimental group, the expression levels of uPA and its receptor were significantly downregulated,and the expression of uPA inhibitor was notably upregulated. These data show that low-frequency ultrasound combined with Tongluo Zhitong herbs attenuates inflammatory reaction in the synovial tissues, by inhibiting the formation of joint fluid and production of inflammatory cytokines, which is an effective treatment for knee osteoarthritis.

Objective To compare the performance of two commercially available ELISA kits for detection of diphtheria IgG antibody to provide data for the proper kit choice. Methods Thirty-three serum samples from staff of the capital airdrome and two standard sera were tested for the evaluation of the kits.Commercial ELISAs were compared with respect to their reproducibility(intra-assay variation and inter-assay variation)and accuracy.Results For the detection of standard serum,intra-assay variation(Coefficient of Variation,CV)was 13.5507% for IBL kit and 5.9541% for Virion kit,the inter-assay variation(CV)was 9.9890% for IBL and 2.4728% for Virion kit.For the serum sample,intra-assay variation(CV)was 14.5270% for IBL and 11.0612% for Virion,the inter-assay variation(CV)11.0039% for IBL and 8.1506% for Virion kit.For the detection of standard serum,inter-assay variation(CV)was 9.9890% for IBL and 2.4728% for Virion.The accuracy was analyzed by variation between the actual concentration and measured concentration of standard serum,the CV was 17.6889% for IBL and 1.3966% for Virion.Conclusion The intra-assay and inter-assay variation of the two kits are generally acceptable(CV

Objective To evaluate the role of protein kinase Cα( PKCα)?nuclear factor E2?related factor 2 ( Nrf2)?heme oxygenase?1 ( HO?1) signaling pathway on endotoxic shock?induced acute lung injury ( ALI) in rabbits. Methods Thirty healthy male New Zealand white rabbits, aged 2 months, weighing 2?0-2?5 kg, were randomly divided into 3 groups ( n=10 each) using a random number table: normal control group ( group C);ALI group ( group ALI);PKCα inhibitor chelerythrine group ( group CHE) . In group CHE, chelerythrine 8 mg∕kg ( in 0?5 ml of DMSO) was injected intraperitoneally, and 30 min later, LPS 5 mg∕kg ( in 2 ml of normal saline) was injected via the auricular vein to induce ALI in ALI and CHE groups. The rabbits were then sacrificed at 6 h after injection of LPS or normal saline, and the lungs were removed for examination of the pathological changes which were scored and for determination of wet∕dry lung weight ratio ( W∕D ratio) , and the expression of Nrf2 and HO?1 protein and mRNA. Results Compared with group C, the pathological score and W∕D ratio were significantly increased, and the expression of Nrf2 and HO?1 protein and mRNA was up?regulated in ALI and CHE groups. The pathological score and W∕D ratio were significantly higher, and the expression of Nrf2 and HO?1 protein and mRNA was lower in group CHE than in group ALI. Conclusion The PKCα?Nrf2?HO?1 signaling pathway is one of the endogenous protective mechanisms underlying endotoxic shock?induced ALI in rabbits.
