Objective To retrospectively analyze the effect of two kinds of biological agents in volume -re-duced bullae .Methods 11 patients who suffered from bullae were operated under large C-arm locating ,and infused two kinds of biological agents through micro catheter of fibreoptic bronchoscopy .All of them were randomly divided into the two groups .The biological agents in group A were fibrinogen and diluent thrombin , and that of group B was Porcine Fibrin Sealant Kit .In group A,the micro catheter with diameter of micro thread less than 1.2mm was placed in bullae through fibreoptic bronchoscope ,and then the 2mL lidocaine,5 ml fibrinogen,and double of 500u diluent thrombin were inproperorder injected through micro catheter .In group B,the Porcine Fibrin Sealant Kit was injected at the same method,and then the suspension fluid was exacted .The operation time was recorded ,and then the clinical efficacy and incidence rate of complications were compared .Results The operation time of group A was 5-15 minutes, and that of group B was 6-20 minutes.For all the patients ,4 cases were totally effective ,2 cases were significantly effective,and 2 cases were totally non-effective.The total effective rate was 81.82%(9/11).The incidence rates of common complications in group A and B were 52.38%(22/42),58.33%(14/24),respectively,the difference was not significant (χ2 =0.22,P>0.05).Moreover,there were no serious complications in all cases .Conclusion The security and effect of two kinds of biological agents might be well enough ,but in view of less cases ,they were worth to further popularized and applied in clinical practice .

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group， model group， positive control group （27 mg/kg allopurinol+0.27 mg/kg colchicine）， Tongfeng li’an capsules low- dose， medium-dose and high-dose groups （2.2， 4.5， 9.0 g/kg）， with 10 rats in each group. Except for normal group， gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically， and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling， serum level of interleukin-1β （IL-1β） and protein expressions of nuclear factor kappa-B （NF-κB） in synovial tissue were detected， and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules （62.5， 125， 250 μg/mL） were given， the levels of nitric oxide （NO）， reactive oxygen species （ROS） and IL-1β in the cells and protein expression of NF-κB were detected， and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group， the swelling degree of the ankle joint， serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group （P＜0.05）； pathological changes such as synovial hyperplasia， edema， vascular congestion， capillary hyperplasia， and increased inflammatory cells were observed. Compared with model group， the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group （P＜0.05）， and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups （P＜0.05）； synovial hyperplasia of the ankle joint improved， and the infiltration of inflammatory cells 2019BS044） decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO， ROS and IL-1β and protein expression of NF-κB（P＜0.01）， and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis， and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.
