0.05),and no adverse reaction was found in both groups.Conclusion:Jianpi Xiaozhang Granule and motilium have obvious and similar therapeutic effect on functional dyspepsia with stagnation of Qi due to spleen deficiency.

AIM: To study the effect of NF-?B "decoy" oligodeoxynucleotides on TNF-? and IL-6 expression in LPS-induced mouse macrophages. METHODS: Mouse macrophage cell line J774.1 cells were cultured with LPS and liposome-mediated oligodeoxynucleotides, and the levels of TNF-? and IL-6 measured in the different culture supernatant by enzyme linked immunosorbent assay. RNA was extracted from macrophages, and the mRNA expression of TNF-? and IL-6 in macrophages was observed by RT-PCR. RESULTS: NF-?B "decoy" oligodeoxynucleotides decreased the expression of TNF-? and IL-6 in LPS-induced macrophages and inhibited generation of TNF-? and IL-6. The level of TNF-? and IL-6 did not change in control group. CONCLUSIONS: NF-?B "decoy" oligodeoxynucleotides inhibit the expression of TNF-? and IL-6 in LPS-induced macrophages, which is probably due to the specific inhibition of activated NF-?B binding sites .

ObjectiveTo investigate the clinical effect of pendulum and straight wire technology in patients with fully erupted second molar.MethodsPatients with Angle class Ⅱ malocclusion were chosen.Control group included patients without erupted second molar.Experimental group included patients with completely erupted second molar.Pendulums were used in two groups to distalize maxillary molars.Then straight wire orthodontic treatment had been performed until treatment was over.Cephalograms of each stage were analyzed.ResultsIn the experimental group,mesiobuccal cusp of first molar was distalized for 4.62 mm,geometric center was distalized for 3.75 mm,about 81 percent of the movement of mesiobuccal cusp.In control group,mesiobuccal cusp of first molar was dis talized for 5.78 mm,geometric center was distalized for 3.20 mm,about 55 percent of the movement of mesiobuccal cusp.It turned out first molar was distalized in both groups,but more rotation took place in control group than that in the experimental group.ConclusionsPendulum can distalize maxillary first and second molars in patients with completely erupted second molar.The pendulum and straight wire technology can treat these patients successfully.

Objective To explore the effect of exercise preconditioning on inflammatory response in ischemic stroke brain tissue which mediated by miR-146a in extracellular vesicles in rats with middle cerebral artery oc-clusion(MCAO),and its mechanism.Methods Sixty 6-week-old male Sprague-Dawley rats were randomly divid-ed into a non-exercise group and an exercise group.The non-exercise group was further divided into a sham-operation control group(C,n=15)and an MCAO model group(M,n=15),while the exercise group was further di-vided into an exercise only group(E,n=15)and an exercise plus MCAO model group(EM,n=15).Rats in the E and EM groups underwent 8 weeks of treadmill exercise,6 days per week,30 minutes per day.Then rats in the M and EM groups received MCAO to induce ischemic stroke,while the C and E groups underwent a sham surgery.Twenty-four hours after the surgery,neurobehavioral tests were performed.Plasma was collected to ex-tract extracellular vesicles,and brain tissue was collected to measure the volume of cerebral infarction by using the triphenyl tetrazolium chloride(TTC)staining.Moreover,the Nissl staining was conducted to observe neuronal and Nissl body.Mean while,the content of miR-146a in plasma extracellular vesicles and brain tissue was mea-sured by using the quantitative polymerase chain reaction(qPCR),and the expression of TNF receptor associat-ed factor 6(TRAF6),nuclear factor kappa-B(NF-κB)and tumor necrosis factor-α(TNF-α)in brain tissues were determined using Western blotting.The targeting relationship between miR-146a and TRAF6 was detected by using the dual luciferase reporter gene assay.Results(1)The neurological behavioral scores of the EM and M groups were higher than those of the C group(P<0.01 and P<0.01),with that of the EM group lower than the M group(P<0.01).(2)TTC staining showed that the infarct volume of the EM and M groups was larger than that of the other two groups(P<0.01 and P<0.01),with that of the EM group smaller than the M group(P<0.01).(3)Nissl staining results showed that the neuronal arrangement was loose,the number of neurons re-duced,and the Nissl bodies were lightly stained and decreased in the M group compared with the C and E groups.Moreover,compared with the M group,the number of neurons and Nissl bodies increased in the EM group.(4)The qPCR analysis showed that the expression of miR-146a in the plasma-derived exosomes and brain tissues of the EM and M groups decreased compared with the C group(P<0.05 and P<0.01),with that of the EM group higher than the M group(P<0.05).(5)According to Western blotting,compared with the C group,the expression levels of TRAF6,NF-κB,and TNF-α proteins increased significantly(P<0.05 and P<0.01),with that of group EM signfiicantly lower than group M(P<0.05 and P<0.05).(6)Dual-luciferase report-er gene assay showed that miR-146a had a specific binding site with TRAF6.Conclusion Eight weeks of exer-cise preconditioning reduces the infarct area and the extent of brain damage,which may be mediated by miR-146a via exosomes,increasing the expression of miR-146a in brain tissue,targeting TRAF6,negatively regulat-ing TRAF6/NF-κB,and reducing the expression of TNF-α,thus alleviating the inflammatory response in brain tissue and exerting a protective effect on ischemic brain injury.

Objective    To provide recommendations for the management of intensive care unit patients without novel coronavirus disease 2019 (COVID-19). Methods    We set up a focus group urgently and identified five key clinical issues through discussion. Total 23 databases or websites including PubMed, National Guideline Clearing-House, Chinese Center for Disease Control and Prevention and so on were searched from construction of the library until February 28, 2020. After group discussion and collecting information, we used GRADE system to classify the evidence and give recommendations. Then we apply the recommendations to manage pediatric intensive care unit in the department of  critical care medicine in our hospital. Results    We searched 13 321 articles and finally identified 21 liteteratures. We discussed twice, and five recommendations were proposed: (1) Patients should wear medical surgical masks; (2) Family members are not allowed to visit the ward and video visitation are used; (3) It doesn’t need to increase the frequency of environmental disinfection; (4) We should provide proper health education about the disease to non-medical staff (workers, cleaners); (5) Medical staff do not need wear protective clothing. We used these recommendations in intensive care unit management for 35 days and there was no novel coronavirus infection in patients, medical staff or non-medical staff. Conclusion    The use of evidence-based medicine for emergency recommendation is helpful for the scientific and efficient management of wards, and is also suitable for the management of general intensive care units in emergent public health events.
