Objective To investigate the safety and feasibility of dyclonine combined with propofol in the application of painless gastroscopy. Methods A total of 90 patients received the painless gastroscopy in our hospi-tal were enrolled from September to December 2016. They were divided into 3 groups according to the random number table(n=30):Dyclonine+propofol(DP)group,Fentanyl+propofol(FP)group,Propofol(P)group. The hemodynamic changes,adverse reaction,propofol dosage,time of gastroscopy examination and time of conscious recovery were observed and recorded. Results Compared with P group,the incidence of hypertension,tachycardia, choking cough,body movement and the dosage of propofol in DP group and FP group were significantly decreased (P<0.05,respectively). Compared with DP group,the incidence of respiratory depression,the time of gastroscopy examination and the time of Conscious recovery in FP group and P group were significantly increased (P < 0.01 , respectively). Compared with FP group,the incidence of nausea and vomiting in DP and P group were significantly decreased (P < 0.05 ,respectively). Conclusions Dyclonine combined with propofol reduced the incidence of cardiovascular response,choking cough,body movement,respiratory depression,and nausea and vomiting,with the reduced dosage of propofol ,the shorten gastroscopy examination time and the recovery time. Therefore ,dyclo-nine combined with propofol is a safe and feasible anaesthesia management for the painless gastroscopy.

Objective:To observe the effect of combining respiratory muscle training with occupational therapy in rehabilitating the upper limb function of stroke survivors.Methods:Fifty stroke survivors with upper limb dysfunction were randomly divided into an observation group and a control group, each of 25. Both groups were given routine rehabilitation treatment including proper positioning of the affected limb, physical therapy and motor function training. The observation group also received progressive resistance training of the inspiratory muscles and respiration control training combined with occupational therapy twice daily for 4 weeks. The trunk control test (TCT), Berg balance scale (BBS), Fugl-Meyer Upper Extremity Assessment (FMA-UE), Action Research Arm Test (ARAT), Modified Ashworth Scale (MAS) for the Hemiplegic Upper Limb and the Modified Barthel Index (MBI) were used to assess the core stability, balance, upper limb functioning, upper limb muscle tension and ability in the activities of daily living of all of the subjects.Results:Before the treatment there were no significant differences in any of the indexes between the two groups. Afterward the average TCT, BBS, FMA-UE, ARAT, MAS and MBI scores of both groups had improved significantly, but the improvements were all significantly greater in the observation group.Conclusions:Combining respiratory muscle training with occupational therapy can further improve the function of the upper limbs and daily living ability beyond what is observed with traditional rehabilitation therapy after a stroke.

Objective: To investigate the effect of activation of the stimulator of interferon genes(STING) pathway on macrophage polarization function and its role in T-cell response. Methods: Mouse macrophage RAW264.7 cells were used.STING signaling related proteins in RAW264.7 macrophage treated with STING agonist diABZI were analyzed by Western blot,including TANK-binding kinase-1(TBK1),interferon regulatory factor-3(IRF3),STING,p-TBK1,p-IRF3,p-STING.The polarization of macrophage RAW264.7 cells treated with diABZI was analyzed by flow cytometry.Co-culture of diABZI-treated RAW264.7 macrophage and T cells was applied to evaluate the change of T cell response. Results: STING signaling related proteins were upregulated in macrophage RAW264.7 cells treated with diABZI for 3 hours.The expression of CD86 was upregulated on the surface of macrophages after 12 hours of diABZI treatment,and the CD86/CD206 ratio was elevated,which presented the M1 polarization phenotype.When coculturing diABZI-treated macrophage RAW264.7 cells with T cells,the cytokine secretion ability of T cells including CD4+T and CD8+T cells was enhanced and the expression of CD107a in CD8+T cells was upregulated. Conclusion STING signaling induces M1 polarization of macrophages which enhance the function of T cells,especially CD8+T cell immune response.
