Objective To explore the efficiency of endoscopic septoplasty with submucous resection for the treatment of 220 patients with deviated nasal septum and report our experience in this field. Methods From May 2006 to May 2010, 220 patients with deviated nasal septum were treated by endoscopic septoplasty with submucous resection to decompress the stress points, resect the deviated parts and implant the reshaped bone of nasal septum, while retaining the normal structure of nasal septum with minimally invasive technique. Results Satisfactory effects were achieved in all the 220 patients, showing centered septal structure and disappeared symptoms such as nasal obstruction, headache and nasal hemorrhage, but no complications including perforation of nasal septum, depressed nasal bridge and septal chalasia and flaring. Conclusion Rhino-endoscopic septoplasty with submucous resection can substantially retain the original structure of nasal septum and thus is proven to be a desirable operation with multiple advantages including minimal invasiveness, quicker healing and fewer complications.

Objective:To determine the effects of enforced expression of Foxp3 in lung cancer cell with regards to proliferation and tumorgeneity. Methods: A stable subline NCIH-hFoxp3 was established by liopfectamin-mediated pcDNA plasmid transfection carrying exogenous hFoxp3. The growth curve and secrection of IL-8 and IL-10 of NCIH-hFoxp3 were evaluated using MTT and ELISA, respectively. The in vivo tumorigeneity was assessed as well by inoculation of NCIH-hFoxp3 subcutaneously in nude mice. Results:Lung cancer cell NCIH-hFoxp3 with enforced expression of Foxp3 proliferated slowly but exihited increased in vivo tumorgeneity compared with corresponding control subline. In addition,increased expression of hFoxp3 in NCIH-hFoxp3 augmented secretion and at-tenuated secretion of IL-8 and IL-10,respectively. Conclusion:Increased expression of Foxp3 may promote progression of lung cancer cell by change of cellular microenvironment and evasion of immune surveillance.

ObjectiveThis paper aims to investigate the potential molecular biological mechanism of Buyang Huanwu Tongfeng decoction in treating hyperuricemia and gouty arthritis by network pharmacology and molecular docking technology and preliminarily verify the mechanism through animal experiments. MethodsThe active ingredients and targets in the Buyang Huanwu Tongfeng decoction were obtained by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and ETCM databases. The DisGeNET and GeneCards databases were utilized to acquire disease targets associated with hyperuricemia and gouty arthritis. These disease targets were then intersected with drug targets to identify key targets. The R language ClusterProfiler package and Python were employed for conducting gene ontology（GO） enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） enrichment analysis. The regulatory network diagram of the drug-key target-function-pathway was visualized using Cytoscape 3.9.1 software， and the protein-protein interaction （PPI） network for key targets was depicted. Finally， the hub gene was determined through topological analysis. Auto Dock， PyMOL， and other software were used for molecular docking to explore the possible therapeutic mechanism of Buyang Huanwu Tongfeng decoction for hyperuricemia and gouty arthritis. In animal experiments， a composite rat model of hyperuricemia induced by intraperitoneal injection of oteracil potassium combined with gouty arthritis induced by the modified Coderre method was established. Through hematoxylin-eosin（HE） staining， uric acid test， enzyme linked immunosorbent assay（ELISA）， Western blot， and real-time polymerase chain reaction（Real-time PCR）， the molecular mechanism and key targets of Buyang Huanwu Tongfeng decoction for treating hyperuricemia and gouty arthritis were observed. ResultsAfter screening and removing duplicate values， 76 active ingredients and 15 key targets were finally obtained. GO enrichment analysis yielded that the treatment of hyperuricemia and gouty arthritis with Buyang Huanwu Tongfeng decoction was significantly associated with acute inflammatory response， astrocyte activation， regulation of interleukin （IL）-8 production， nuclear receptor activity， and binding of growth factor receptor. KEGG pathway enrichment analysis obtained that the key target genes were significantly associated with the IL-17 signaling pathway， advanced glycosylation end/receptor of advanced glycation endproducts（AGE/RAGE） signaling pathway， anti-inflammatory， and other pathways. PPI network indicated that albumin（ALB）， peroxisome proliferator-activated receptor-γ （PPAR-γ）， IL-6， IL-1β， and C-reactive protein（CRP） were the key protein targets. The molecular docking results showed that ALB had the strongest binding force with beta-carotene （β-carotene）. Biochemical results showed that blood uric acid decreased in the Buyang Huanwu Tongfeng decoction groups. HE staining results showed that the low-dose （7.76 g·kg^-1·d^-1）， medium-dose （15.53 g·kg^-1·d^-1）， and high-dose （31.05 g·kg^-1·d^-1） groups of Buyang Huanwu Tongfeng decoction had different degrees of remission， and the remission of the high-dose group was the most obvious. Fibroblastic tissue hyperplasia in synovial joints accompanied with inflammatory cell infiltration， as well as inflammatory cell infiltration in renal tissue of the high-dose group was significantly reduced， followed by the medium-dose and low-dose groups， and the expression of ALB， PPAR-γ， IL-6， IL-1β， and CRP was down-regulated to different degrees. ConclusionBy regulating the targets such as ALB， PPAR-γ， IL-6， IL-1β， and CRP， inhibiting the PPAR-γ/nuclear transcription factor （NF）-κB pathway， and reducing AGEs/RAGE-mediated inflammation， Buyang Huanwu Tongfeng decoction exerts anti-inflammatory and analgesic effects and activates blood circulation and diuresis in the treatment of hyperuricemia and gouty arthritis.
