ABSTRACT
As an important means of lung protective strategy, prone position ventilation (PPV) which can effectively shorten the time of mechanical ventilation, significantly reduce the mortality of patients with acute respiratory distress syndrome (ARDS), and is suitable for popularization and application in the ICU. However, some studies show that prolonged prone position can significantly increase the incidence of Stress injury, making it difficult to implement PPV in the practical level. In order to achieve the goal of safe and effective prevention of skin Stress injury, and to promote the correct implementation of PPV, this paper review the methods of preventing Stress injury in patients with PPV.
ABSTRACT
Objective:To investigate the theraputic effect of STAT3 Decoy-ODN combined with chemotherapy drugs for HCC commonly used in clinical,include doxorubicin (DOX),5-fluorouracil (5-Fu) and cisplatin;and,analyzing the impact of combination therapy on the immune system.Methods:MTT assay was used to detect cell proliferation,and Annexin-V /7AAD double staining assay was used to detect the apoptosis of Decoy ODN transfected-hepatoma cells treated with chemotherapy drugs.The tumor growth and survival rate of H22 tumor-bearing mice treated with DOX combined with STAT3 Decoy-ODN or not were observed.FACS was applied to analyze the subpopulation and activation of PBMCs from tumor-bearing mice treated as above,and to evaluate the influence of DOX or DOX-treated tumor cells on spleen lymphocyte activation.Results: DOX-induced the suppression and the apoptosis of H22 were significantly increased by Decoy ODN transfection.The combination treatment of Decoy ODN and DOX significantly reduced H22 tumor growth and extended the survival of tumor-bearing mice.Low-dose DOX could increase the proportion of T cells and CD69+T cells in PBMCs,as well as the expression of CD107a and IFN-γin NK cells.DOXt-reated H 22 cells increased the proportion of T cells.Conclusion:Targeted blocking STAT3 could enhance the sensitivity of liver cancer cells to doxorubicin.So,combination therapy may improve DOX therapeutic effect and reduce DOX-mediated side effects.Furthermore,low dose of DOX can promote the activation of host immune system by acting on tumor cells.
ABSTRACT
RNA interference mediated by short interfering RNA is widely used to study functional genes and also being developed for therapeutic applications. However, recent study demonstrated that siRNA might activate innate immune system and induce huge production of inflammatory cytokines in mammals, and also randomly inhibit expression of undesired genes. Designing highly effective siRNAs or modifying the siRNA to retain or enhance the silence efficiency and meanwhile abolish the off-target effects associated with immunostimulation then become the key techniques in application of siRNAs as safe and effective therapeutic agents.
ABSTRACT
Objective To observe teletherapy and local hyperthermia effects on VX2 carcinoma rabbits'cytokines and curative effect. Methods 60 male white health rabbits were selected, and divided them into three group. The group of teletherapy were 20. The group of local hyperthermia were 20. So were the group of comparison. Their tumors' changes, rates of death and changes of IL-2, IL-6, IL-8, TNF, IGF, CA-50 before and after VX2 carcinoma replanted and those treated after one, three, four weeks were observed. Results The diameters of tumors and rates of death from large to small in turn was comparison's group, hyperthermia's group and teletherapy's group. After VX2 carcinoma replanted IL-2, IL-8 were low but IL-6, TNF, IGF, CA-50 were high. After being treated one, three or four weeks, IL-2, IL-8 were getting lower and lower but there was significant difference between teletherapy's group with other group in IL-2 and IL-8(P
ABSTRACT
OBJECTIVE:To compare different prescription strategies of antibiotics in the management of acute upper respiratory tract infection(AURTI).METHODS:A total of 984 patients with AURTI were divided into three groups:antibiotic group(treated with antibiotics throughout the course),delayed group(delayed use of antibiotics),and none-antibiotic group(receiving no antibiotics).The course of diseases,rate of return visits,incidence of adverse drug reactions(ADR)and total trea-tment costs were analyzed statistically.RESULTS:Course of diseases was the longest in the antibiotic group(P
