Objective To investigate the combined use of osteoarthritis treatment effect of lornoxicam and peptide drugs.Methods 260 patients with osteoarthritis treated in our hospital from May 2014 to June 2016 were selected, were randomly divided into study group and control group, each group of 130 cases.The patients in the control group were treated with sodium hyaluronate and lornoxicam, the study group was given bone peptide on the basis of the control group. The pain scores, knee function and adverse reactions were compared between the two groups.Results There was no significant difference in VAS and WOMAC scores between the two groups before treatment; after treatment, the improvement of VAS and WOMAC score in the study group was better than that in the control group (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups. Conclusion Sodium hyaluronate, bone peptide, lornoxicam and other drugs in the treatment of patients with osteoarthritis clinical efficacy is obvious, and fewer adverse reactions.

The article reviewed the research progress of ligustilide in recent years and elaborated its pharmacological functions and mechanisms in detail,especially in ischemic brain injury.Its mechanism includes reducing cerebral infarct volumes and improving neurobehavioral deficits,anti-oxidant and anti-apoptosis,antithrombotic activity,calcium channel blockers function,and effect on erythropoietin.Other pharmacological effects of ligustilide including inhibiting vascular smooth muscle cell proliferation,anti-inflammatory and analgesic effects,effects on LPS-induced endotoxic shock,inhibiting constriction effect,suppression of the central nervous system,and ameliorating the memory impairment induced by scopolamine and so on,are also introduced.Ligustilide has potential pharmacological value,which provides a reference for its further research and development.

Objective To explore the clinical application of a new laryngeal mask in implantation of tracheal stent.Methods The new laryngeal masks were implanted under general anesthesia for 20 patients with tracheal or primary bronchus stenosis.The oxygen was continuously supplied from its side hole,and the stents were subsequently implanted from the tail hole.Results By using the new laryngeal masks under general anesthesia,all of 20 patients were successfully and leisurely implanted the tracheal stent.After the operation,the dyspnea symptoms were significantly improved,and there was no complication.Conclusion Stent implantation by using the new laryngeal mask under general anesthesia will provide a safe and effective treatment for tracheal stenosis.

Objective : To investigate the mechanism of miRNAs in glycyrrhizic acid treatment of alcohol⁃induced liver injury in rats . Methods : 45 male SD rats were randomly divided into glycyrrhizin group , model group and control group . The rats in glycyrrhizin group were given 56% liquor and glycyrrhizin , the rats in model group were given 56% liquor , and the rats in control group were given distilled water for 8 weeks . The blood was collected and the serum was separated by centrifugation to detect the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) . RNA were extracted from liver tissues , miRNAs were detected by rat miRNA microarray , and their expression levels were analyzed . The miRNA target genes of differential miRNA were predicted . Gene Ontology (GO) and KEGG Pathway enrichment analysis were used to understand the function of differential miRNA , and the differential miRNA⁃mRNA⁃Pathway regulatory network was constructed using Cytoscape to further screen the regulatory key miRNA and key pathways . qRT⁃PCR was used to verify the expression of selected miRNA . Results : Compared with the model group , the glycyrrhizin group could significantly improve the liver tissue lesions , and reduce the liver serum AST and ALT levels (P < 0. 05) . Compared the microarray data of glycyrrhizin group and model group , a total of 13 differentially expressed miRNA were screened ( P < 0. 05 , fold change ≥ 1 . 5) , of which 10 were up⁃regulated and 3 were down⁃regulated . The GO classification annotation of differential miRNA target genes showed that differential miRNA were related to cell adhesion , antioxidant activity , metabolic process , biological process regulation , cell killing , immune system and other functions . The KEGG Pathway analyling pathway , Hippo signaling pathway , PI3K⁃Akt signaling pathway , wnt signaling pathway , apoptosis and other signaling pathways might play an important regulatory role in the improvement of alcoholic liver injury by glycyrrhic acid . Conclusion This study established the miRNA expression profile of glycyrrhizin in the treatment of alcoholic liver injury in rats , suggested that miR⁃615 , miR⁃107 ⁃3p and miR⁃292⁃5p might play an important role in the treatment of alcoholic liver injury by glycyrrhizin .

Osteosarcoma is a kind of bone tumor with highly proliferative and invasive properties, a high incidence of pulmonary metastasis and a poor prognosis. Chemotherapy is the mainstay of treatment for osteosarcoma. Currently, there are no molecular targeted drugs approved for osteosarcoma treatment, particularly effective drugs for osteosarcoma with pulmonary metastases. It has been reported that fibroblast activation protein alpha (FAPα) is upregulated in osteosarcoma and critically associated with osteosarcoma progression and metastasis, demonstrating that FAPα-targeted agents might be a promising therapeutic strategy for osteosarcoma. In the present study, we reported that the FAPα-activated vinblastine prodrug Z-GP-DAVLBH exhibited potent antitumor activities against FAPα-positive osteosarcoma cells in vitro and in vivo. Z-GP-DAVLBH inhibited the growth and induced the apoptosis of osteosarcoma cells. Importantly, it also decreased the migration and invasion capacities and reversed epithelial-mesenchymal transition (EMT) of osteosarcoma cells in vitro and suppressed pulmonary metastasis of osteosarcoma xenografts in vivo. Mechanistically, Z-GP-DAVLBH suppressed the AXL/AKT/GSK-3β/β-catenin pathway, leading to inhibition of the growth and metastatic spread of osteosarcoma cells. These findings demonstrate that Z-GP-DAVLBH is a promising agent for the treatment of FAPα-positive osteosarcoma, particularly osteosarcoma with pulmonary metastases.
