Objective:To understand the cognitive differences and its influential factors of medical dispute and physician′s professionalism between medical personnel and patients, and further to provide evidence for the preven-tion and treatment of medical dispute. Methods:In the case of quality control, we surveyed on the cognitive of medical dispute and physician′s professionalism in medical personnel and patients using self-designed question-naire. Stratified cluster sampling method was used in this study, which recruited 847 medical workers and 577 pa-tients. Data analysis was conducted with SPSS 16. 0. The two sample rates were compared using Chi squaretest (α=0. 05). Results:There is a statistically significance in doctor-patient relationship evaluation, dispute pre-vention, dispute responsibility, fair treatment,impact on the doctors and patients, causes of medical disturbance, attitude tomedical disturbance, medical disturbance elimination, physician′s professionalism evaluation, improve-ment approach, and the physician′s professional value between the two samples, having a direct impact on the con-struction of physician′s professionalism. Conclusion:For medical personnel, they should strengthen the construc-tion of physician′s professionalism and establish effective mechanism to prevent medical dispute. For patienes, they should understand, trust and respect the doctors, and solve medical dispute rationally. For government, they should establish a reasonable mechanism for the settlement of medical dispute, create a rational atmosphere respon-ding to the medical dispute, and reduce the intensification of medical dispute.

Objective To investigate the level of IL-17 and its clinical significance in patients with primary Sj(o)gren's syndrome (pSS) complicated with interstitial lung disease (ILD).Methods IL-17 levels were detected by enzyme linked immunosorbent assay (ELISA) in 53 untreated patients with pSS (25patients with only lacriminal and/or salivary gland involvement,28 with only interstitial lung disease involvement) and 15 healthy controls.The related clinical and laboratory data were recorded.ANOVA,LSDtest and Pearson test were used for statistical analysis.Results There were significant differences between the 3 groups(F=22.504,P=0.000).The mean concentration of sera IL-I7 in the patients with ILD was significantly higher than in patients with only lacriminal or salivary gland involvement (P＜0.05).There was no difference in the levels of sera IL-17 between the patients with only lacriminal and/or salivary gland involvement and healthy controls (P＞0.05).Conclusion Our results show that patients with pSS concomitant with ILD have high serum IL-17 levels,which highlight the role of IL-17 in Sj(o)gren's syndrome interstitial lung injury.

Objective:To investigate the effects of a stannous-containing sodium fluoride dentifrice and crisscross bristle manual tooth-brush in the management of dental plaque and gingivitis.Methods:249 cases with gingivitis were enrolled in an office-based study. The study was unsupervised and single-centered with open-label and self-control.At baseline,gingival health and plaque coverage were assessed by dentists using categorical scales.Participants were given stannous containing sodium fluoride dentifrice and crisscross bristle design manual brush,and were instructed to use the products by manufacturer's usage instructions twice daily for 30 days.At the end of 30 days,plaque and gingivitis were reassessed using the same categorical scales.Results:232 participants(1 78 females and 54 males) completed the study.Gingivitis data of 5 cases and dental plaque data of 3 cases were not judgable.After 30 days of product use,226 cases(99%)showed noticeable improvement in their gingival health;227(96%)cases showed improvement in overnight plaque cover-age.Conclusion:Stannous-containing sodium fluoride dentifrice in combination with crisscross bristle toothbrush is effective in the management of gingivitis and dental plaque.

Pin1 (peptidyl-prolyl cis-trans isomerase NIMA-interacting 1) belongs to peptidyl-prolyl cis-trans isomerase (PPIase) and is a novel promising anticancer target. Based on the lead structure of benzophenone, a series of novel diarylether derivatives containing a pyrimidine ring were designed and synthesized. The inhibitory activities on Pin1 of compounds 5a-5d and 6a-6i were evaluated by a protease-coupled enzyme assay. Of all the evaluated compounds, 6 compounds displayed inhibitory activities. Molecular docking was performed using FlexX algorithm to explore the binding mode of the active molecules.

Objective:To study the influence of objective structured clinical examination (OSCE) assessment mode on learning interest and critical thinking of nursing students in operating room.Methods:There were 49 operating room nursing students from April 2019 to April 2020 who were selected as the observation group, receiving the teaching and assessment mode of OSCE. In addition, 49 operating room nursing students from March 2018 to March 2019 were included as the control group, receiving the conventional teaching and assessment mode. The nursing students' learning attitude scale was used to compare the learning interest of the two groups, and the critical thinking level of nursing students was recorded by Chinese critical thinking disposition inventory-Chinese version (CTDI-CV). SPSS 24.0 software was used to analyze the data with t test and chi-square test. Results:There were statistically significant differences in the scores of learning interest, learning experience, learning habits, professional cognition and the total scores of the learning attitude of nursing students after the assessment between the observation group and the control group ( t=4.861, t=4.885, t=3.466, t=4.206, t=8.292; all P<0.05). There were statistically significance of curiosity, truth seeking, open thinking, analytical ability, systematic ability, self-confidence in thinking, cognitive maturity and the CTDI-CV total scores after the assessment between the observation group and the control group ( t=4.262, t=4.311, t=2.754, t=4.854, t=3.984, t=2.864, t=4.267, t=2.729; P<0.05). Conclusion:The OSCE assessment mode used in operating room for nursing students is helpful to improve the learning interest and the cultivation of students' critical thinking.

Objective:To investigate the effect of electroacupuncture treatment on the integrity of myelin and the related molecules in the spinal dorsal horn of neuropathic pain model rat.Methods:Totally 32 SPF grade Sprague-Dawley rats were randomly divided into 4 groups: sham group, pain model group, electroacupuncture group and sham electroacupuncture group, with 8 rats in each group. Neuropathic pain model was established by right sciatic nerve ligation. Electroacupuncture stimulation of Huantiao point and Yanglingquan point was started from 1 day after surgery, 30 min/d, and lasted for 14 days. The paw withdraw mechanical threshold (PWMT) were tested before surgery, 3 days, 7 days and 14 days after surgery. Immunofluorescence was used to detect myelin basic protein (MBP) in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn and Western blot was used to measure the expression of β-secreatase 1(BACE1), neuregulin 1 type Ⅲ (NRG1 Ⅲ) and phosphorylated ErbB receptor tyrosine kinase 2 (p-ErbB2) at 14 days after surgery.SPSS 24.0 was used for statistical analysis.Repeated measurement ANOVA was used for behavioral analysis and one-way ANOVA followed by Bonferroni test was used for Western blot and immunofluorescence data analysis.Results:(1) The results of pain behaviors showed that the interaction effect of time and group on PWMT was significant ( F=29.817, P<0.001), and both the time main effect ( F=240.598, P<0.001) and group main effect ( F=304.291, P<0.001) were significant. There were no significant differences among 4 groups before surgery. Compared with pain model group, the PWMT of electroacupuncture group were significantly increased at 3 days ((16.87±1.82) g, (11.31±1.36) g), 7 days ((15.09±1.75) g, (10.33±0.73) g) and 14 days ((15.07±1.49) g, (9.87±0.98) g) after surgery (all P<0.01). (2)The difference of the intensity of MBP in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn staining was significant among 4 groups ( F=92.06, P<0.001). Compared with sham group, the intensity of MBP staining in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in pain model group was significantly decreased ((13.26±1.90)%, (36.37±0.68)%) ( P<0.01) ). Compared with pain model group, the intensity of MBP staining in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in electroacupuncture group ((28.21±3.15)%) was significantly increased after electroacupuncture treatment ( P<0.01). (3) The differences of the expressions of BACE1, NRG1 Ⅲ and p-ErbB2 in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn were significant among the 4 groups ( F=31.04, 21.20, 11.74, all P<0.01). Compared with sham group, the expressions of BACE1, NRG1 Ⅲ and p-ErbB2 in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in pain model group were significantly downregulated (BACE1 (0.42±0.09), (1.16±0.13); NRG1 Ⅲ (0.54±0.05), (1.00±0.10); p-ErbB2 (0.73±0.06), (1.02±0.15) ) (all P<0.05). Compared with pain model group, the expression of BACE1 (0.86±0.09), NRG1 Ⅲ (0.81±0.05) and p-ErbB2 (1.12±0.04) in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn in electroacupuncture group were upregulated(all P<0.05). Conclusion:Electroacupuncture treatment could relieve neuropathic pain, improve the demyelination and upregulate the expressions of myelin-related proteins in the ipsilateral Ⅰ-Ⅲ laminae of spinal dorsal horn.

Objective:To observe the therapeutic effect of Kesuting syrups and Keqing capsules, which have the function of promoting lung and resolving phlegm, on a mouse model combining disease and syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking lung. Method:The therapeutic effects of Kesuting syrups (the doses of 22, 11 mL·kg^-1) and Keqing capsules (the doses of 1.155, 0.577 5 g·kg^-1) on this model were evaluated by the inflammatory changes of lung tissue, the expression of viral nucleic acid, the contents of inflammatory factors [interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α and interferon-γ (IFN-γ)], and the percentages of immune cells in peripheral blood (CD4⁺ T cells, CD8⁺ T cells and B cells). Result:Compared with the model group, high- and low-dose groups of Keqing capsules and Kesuting syrups could significantly reduce the inflammatory damage in the lung tissues of mice, Keqing capsules could significantly increase the percentages of CD4⁺ T cells, CD8⁺ T cells and B cells in peripheral blood, Keqing capsules and Kesuting syrups could reduce the expression levels of IL-6, IL-10, TNF-α and IFN-γ, inhibit the viral load in lung tissue, as well as improve the pathogenic manifestations of lung tissue. Conclusion:As the first-line drugs for novel coronavirus pneumonia, Keqing capsules and Kesuting syrups have significant therapeutic effect on the mouse model combining disease and syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking lung, and the mechanism may be related to regulating immune function and reducing cytokine storm.
