Objective] The mechanism of astragalus polysaccharides treatment of asthma was discussed. [Methods]Through the domestic and foreign about traditional Chinese medicine monomer astragalus polysaccharide on IL-4, IL-10 and other cytokines and inflammatory infiltrates aspects such as the Th1/Th2 balance, smooth muscle actin and airway mucus in the airway remodeling and asthma related gene research literature summary. [Results] Improve airway inflammation astragalus polysaccharides from activation and inhibition EOS EOS infiltration reduction, regulating Th1/Th2 imbalance, so Th0 cells to Th1 cell differentiation, and inhibiting the release of inflammatory cytokines and other aspects, APS can reduce airway hyper-responsiveness mitigate aspects peribronchial infiltration of eosinophils and airway smooth muscle cells induced byα-SMA expression and other high alleviate airway remodeling. [Conclusion] The influence of astragalus polysaccharide on asthma gene research will lay the basis for study of the mechanism of treatment of asthma, monomer research provides new ideas for traditional Chinese medicine.

Cyclooxygenase-2 (COX-2) plays an important role in the development of leukemia.COX-2 inhibitor plays a certain anti-leukemia role in the process.Many studies show that COX-2 inhibitor plays antileukemia role by inhibiting the proliferation of leukemia cell,promoting apoptosis,affecting cell cycle,inhibiting cell metastasis and reversing cell drug resistance and so on.Therefore,the researches about the anti-leukemia mechanisms of COX-2 inhibitor will provide a new target in clinical prevention and treatment of leukemia.

BACKGROUND:Currently, a large number of studies have confirmed that macrophage migration inhibitory factor plays an important role in a variety of biological activities, such as tumor development. In recent years, it also plays an important role in the inflammatory process, and has achieved a lot of results. However, it is unclear whether and how the macrophage migration inhibitory factor plays a role around the oral implant under oral environment.
OBJECTIVE:To investigate the effect of macrophage migration inhibitory factor on the inflammation of bone marrow mesenchymal stem cels growing around the titanium implant.
METHODS:First, bone marrow mesenchymal stem cels were seeded onto titanium cel culture disks to simulate the peri-implant environment in the mouth, and then, the cels were divided into four groups: control group, without any stimulation; lipopolysaccharide group, lipopolysaccharide-induced inflammation of bone marrow mesenchymal stem cels; non-specific smal interfering RNA (siRNA)+lipopolysaccharide group, non-specific siRNA-transfected and lipopolysaccharide-induced cels; macrophage migration inhibitory factor siRNA+lipopolysaccharide group, cels under the stimulation of lipopolysaccharide were transfected with macrophage migration inhibitory factor.
RESULTS AND CONCLUSION: Using flow cytometry, the cels expressing over 95% CD29 and CD90 as wel as less than 5% CD 45 were selected in the experiment. Cel counting kit-8 test showed that macrophage migration inhibitory factor siRNA+lipopolysaccharide had no influence on the proliferation of bone marrow mesenchymal stem cels. Lipopolysaccharide significantly stimulated the inflammatory reactions of bone marrow mesenchymal stem cels, which was 15-20 times of the control group (P < 0.01). However, compared with the lipopolysaccharide group, the levels of interleukin-1β, interluekin-6 and tumor necrosis factor-α were increased significantly after transfection with macrophage migration inhibitory factor siRNA+lipopolysaccharide stimulation (P < 0.01). These findings indicate that lipopolysaccharide can promote inflammation of bone marrow mesenchymal stem cels around the oral implant, but macrophage migration inhibitory factor siRNA can, to some extent, inhibit the occurrence of inflammation.

AIM:To investigate the influence of free hemoglobin on the initiation and progression of atherosclerosis and the role of CD163 in this process.METHODS:Thirty male SD rats were randomly divided into three groups:control group(group C),atherosclerosis group(group A),atherosclerosis and hemolysis group(group P).The hemolysis and atherosclerosis animal model was established.The free hemoglobin(FHb)and MDA levels in plasma,(RAAPIs)and intima area/midmembrane area(I/M)of each group were measured.The expressions of CD163 and heme oxygenase-1(HO-1)in atherosclerosis plaques in group A and P were detected and measured by means of immunohistochemistry and Western blotting.RESULTS:Compared with group C,the FHb,MDA,CD163 and HO-1 in group A and group P increased significantly(P0.05).The FHb level in plasma and the expressions of CD163 and HO-1 in atherosclerotic plaques correlated with each other(r=0.526,r=0.498,r=0.653;P

Objective To assess the benefit of intraoperatively placed nasointestinal feeding tubes for early postoperative enteral nutrition.Methods The retrospective study was carried out on 19 cases of in-fants with long gap esophageal atresia who underwent one-stage operation in Xinhua Hospital from January 2006 to December 2013.Patients were divided into two groups according to whether the transanastomotic na-sointestinal feeding tubes(TNFT)were placed.Demographics,associated anomalies,operative findings,com-plications,duration of enteral nutrition(EN),length of stay were analyzed.Results Thirty-seven patients had long gap esophageal atresia and nineteen underwent one-stage operation.Eight patients were identified as TNFT group while eleven patients were identified as nonfeeding tube(NFT)group.There was no significant differences between the two groups in gestational age,birth weight,associated anomalies,anastomotic leak, weight gain,ICU-free days and length of stay(P>0.05).But the ventilator-free days(23.5 d vs.19.3 d), first EN time(0.8 d vs.9.1 d)and total EN feeding time(15.9 d vs.21.4 d)between the two groups were significantly different(P<0.05 ).Conclusion Intraoperatively placed TNFT may lead to earlier EN feeding and shorter parenteral nutrition duration,but a larger prospective study would be required to prove the benefits and ensure the safety.

After the importance to construct academic native resource repository platform was elaborated,the native resource repository platform designed and constructed by Library of Second Military Medical University according to the demands of Second Military Medical University was described, which improved the management efficiency of scientific research and academic achievements.

Objective To investigate the prevalence of urinary incontinence among Uigurs in Xinjiang district. Methods 506 adults Uigurs (over 18 years old)in Xinjiang, 200 men and 306 women, were interviewed with questionnaire. Results The total incidence of urinary incontinence was 38.9%, 43.8% in women and 31.5% in men, P

Objective:To investigate the methods and nutritional effects of endoscopic jejunal ac cess for enteral feeding.Methods:106 cases placed jejunum feeding tube were randomly divided into the observation group and the control group,54 cases in the observation group and 52 cases in the control group.43 patients underwent nasogastric enteral nutrition were as the nasogastric tube group.The traditional endoscopic jejunal access method was used in control group,and the modified endoscopic jejunal access method was used in observation group.The operation time,the success rate of indwelling,complications and nutritional indexes were compared among these three groups.Results:The operative time of the observation group and nasogastric tube group was significantly shorter than that of the control group (P ＜ 0.05).The success rate of indwelling was significantly lower in the control group (P ＜ 0.05).There was no significant difference in the incidence of postoperative complications among these three groups (P ＞ 0.05).After intubation and nutritional treatment in all the groups,hemoglobin,plasma albumin and serum albumin levels were significantly improved (P ＜ 0.05).There were no significant differences in nutritional indexes between the observation group and the control group (P ＞ 0.05).The levels of hemoglobin,plasma albumin and plasma prealbumin in nasogastric tube group were significantly lower than those in the observation group and the control group (P ＜ 0.05).Conclusion:Modified endoscopic jejunal access for enteral feeding can effectively shorten the intubation operation time and improve success rate and nutritional indexes.
