Emergency departments of hospitals are exposed to risks of patient complaints and disputes, and the emergency department of a stomatology hospital is no exception. Medical disputes at the emergency department of Peking University Stomatology Hospital, as registered at the department of medical affairs of the hospital in the past ten years, are analyzed with statistical processing. The results are used in studying characteristics of medical disputes frequently found in stomatology emergency cases, for references and recommendations on prevention and avoidance of such disputes in future.

Objective To investigate the effect of bifidobacterium (Bif) supplementation on acute inflammatory response in murine dextran sulfate sodium(DSS)-induced colitis, and its possible mechanism. Methods Mice were divided into four groups: control,DSS, salfasalazine (SASP) and Bif. The mice in groups DSS, SASP and Bif were fed with 5% DSS(w/v) solution for 7 days to induce colitis, and disease activity index (DAI) was calculated every day. The mice in group SASP were fed with SASP every day during inducing colitis, and the mice in Bif group were given Bif by oral gavage from 7 days before the experiment to the end of experiment. The expression of TNF-?、NF-?B P65 and myeloperoxidase (MPO) in inflamed colon of each group was measured at the end of experiment. Results The mice in groups SASP and Bif showed a lower DAI than those in group DSS since the forth day to the end of experiment. There were lower level of TNF-? and MPO in murine inflammatory colon, and lower NF-?B P65 expression in nuclei of inflammatory cells in groups SASP and Bif than those in control at the end of experiment. Conclusions Treatment with Bif can effectively inhibit proinflammatory cytokine secretion and NF-?B activation in inflammatory cells, and decrease colonic inflammatory response in DSS induced colitis.

Objective To explore the effect of formaldehyde on learning and memory and the activity of superoxide dismutase (SOD) in the cerebral tissues. Methods 40 ICR mice were randomly divided into four gropes: A-control group (NS was added into water bottle), B, C, D-three formaldehyde dose groups (0.1, 0.2, 0.4% formaldehyde solution were added into water bottles). After 30 days of treatment, the ability of learning and memory were evaluated by Morris watermaze test and step-down test and the activity of SOD in the cerebral tissues was determined. Results In the Morris watermaze test (the fifth day), escapelaten latence in group C[ (29.23?5.56)s] and D[ (37.36?7.39)s] were significantly longer than group A[ (21.65?5.81)s](P

Objective Among the factors affecting embryo implantation, oxidative stress is one that receives much medical attention. The purpose of the study was to explore the effect of H2 O2 on the endometrial stromal cells ( ESCs) in the decidual mouse model of oxidative stress of ESCs. Methods Primary ESCs cultured by enzymatic digestion with a mesh filter were divided into a control, an experimental, and a model group. Decidualization was induced in the mice of the experimental and model groups by inter-vention with 10 nM E2 and 1μmol/L P4 for 72 h in vitro. Then, the animals of the model group were treated with different concentra-tions of H2 O2 for 4 hours. The primary ESCs were identified by immunohistochemistry, the expression of dPRP mRNA determined byRT-PCR, the proliferation of the decidual ESCs treated with H2 O2 analyzed by CCK-8, and the level of ROS detected by flow cytometry. Results Primary mouse ESCs were successfully isolated, cultured, and identified, which were shaped like spindles and polygons, radial-ly aligned under the microscope. Immunofluorescence analysis showed positive expression of vimentin and negative expression of cytokeratin. The purity of the primary mouse ESCs was ( 96. 3 ± 0. 49 )%. Theexpression of dPRP mRNA was significantly higher in the ESCs treated with E2 and P4 than in the control (0.0002±0.0000 vs 1.0010±0.0011, P<0.01). H2O2 at ≥150μmol/L suppressed the proliferation of the decidual ESCs by 6.9% (P<0.05), and in a concen-tration-dependent manner, reaching the maximum inhibition rate of 70.6% at the concentration of 300μmol/L. The level of intracellular ROS was markedly increased in the ESCs treated with H2O2 at 50μmol/L (27.77±4.20) and 100μmol/L (43.57±6.58), with statisti-cally significant difference from that in the control group (17.47±0.61) (P=0.001). Conclusion H2O2 at 100μmol/L can signifi-cantly elevate the intracellar ROS level without affecting the proliferation of decidual primary ESCs, and therefore can be used for estab-lishing the model of oxidative stress of ESCs in decidual mice.

Course construction is the groundwork for vocational college to improve education quality. The first thing for the excellent course construction is to raise awareness. The fundamental starting point and destination are benefitial to students. It must start from the teachers themselves, and have entire optimization in the teaching content,teaching methods ,teaching materials, the means of teaching and so on.

Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.
