0.05).The levels of serum TC in groups A,B,and C were (23.51?10.58),(14.27?3.51)and(1.36?0.33)mmol?L-1, respectively; the levels of serum LDL in groups A,B,and C were (21.39?10.00),(14.23?4.01)and(0.72?0.35)mmol?L-1;there were significant differences between three groups (P0.05).Conclusion High-fat diet has no significant effect on the expressions of NO and PAI-1 in atherosclerosis rabbits .Atorvastatin can increase the expression of NO and decrease the expression of PAI-1,and can inhibit the progression of atherosclerosis.

Objective: To investigate the factors related to cardiac dysfunctions during the percutaneous coronary intervention (PCI) in patients with non-ST segment elevation acute coronary syndrome (NSTEACS). Methods: Patients diagnosed as NSTEACS receiving PCI from September 2007 to June 2018 were collected in the data base of medical record management system in Qingdao Eighth People′s Hospital. Patients with cardiac dysfunctions (≥ Killip Ⅱ grade) within 1 week after PCI were included into the case group, while patients with normal cardiac function (Killip Ⅰ grade) within 1 week after PCI were included into the control group. Firstly, baseline data of age, gender, histories of hypertension, histories of type 2 diabetes, histories of high cholesterol, histories of smoking, histories of drinking, histories of myocardial infarction, NSTEACS risk stratifications, the application of platelet glycoprotein (GP)Ⅱb/Ⅲa receptor antagonists, coronary artery SYNTAX scores, the dose of contrast agent during PCI, the peak cardiac troponin (cTnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) within 24 h after admission was compared between the two groups; then, factors with statistical differences (P < 0.05) were analyzed by the multivariate logistic regression; at last, variables screening was performed through the backward method and likelihood ratio test. Results: A total of 3927 patients with NSTEACS receiving PCI were enrolled. After patients with incomplete information were eliminated, 313 patients were admitted to the case group and 2 906 patients were admitted to the controlled group. After the analysis of multivariate logistic regression and variables screening, it showed that >80 years old (OR = 1.758, 95% CI 1.129 to 2.367, P = 0.014), increased dose of contrast agent (OR = 1.083, 95% CI 1.007 to 1.274, P = 0.020), the peak cTnT>0.2 μg/L (OR = 2.102, 95% CI 1.703 to 3.104, P = 0.031) and NT-proBNP>450 ng/L (OR = 2.243, 95% CI 1.863 to 3.257, P = 0.015) after admission were the risk factors of cardiac dysfunctions. Conclusions Advanced age (>80 years old), increased dose of contrast agent during PCI, the peak cTnT>0.2 μg/L and NT-proBNP>450 ng/L within 24 h after admission could raise the risk of cardiac dysfunctions in patients with NSTEACS after PCI.

OBJECTIVE:To evaluate the effects and safety of Bencycloquidium bromide nasal spray in the treatment of acute rhinitis after a cold. METHODS:A multicenter,dose parallel controlled,randomized,double-blind,placebo-controlled clinical tri-al was conducted.

Objective To investigate the factors related to slow-flow (SF) or no-reflow (NR) during the percutaneous coronary intervention (PCI) in patients with non-ST segment elevation acute coronary sydrome (NSTEACS). Methods Patients diagnosed as NSTEACS who received PCI from September 2007 to June 2018 were collected through the data base of medical record management system in Qingdao Eighth People′s Hospital.The blood flow≤TIMI 2 grade during PCI was defined as slow-flow (SF) or no-reflow(NR). Patients with SF or NR were included into the case group and patients without SF or NR were included into the controlled group. Factors of age, gender, history of hypertension, history of type 2 diabetes, history of high cholesterol, history of smoking, history of drinking, NSTEACS risk stratification, the application of platelet glycoprotein (GP) ⅡB/ⅢA receptor antagonist, coronary artery SYNTAX score, culprit blood vessels, times of balloon dilatation, the burden of thrombus and the preoperative TIMI grade of blood flow were analyzed by multivariate Logistic regression. Then, variables screening was performed through backward method and likelihood ratio test. Results A total of 3 927 patients with NSTEACS receiving PCI were enrolled. After patients with incomplete information were eliminated, 143 patients were admitted to the case group and 3 588 patients were admitted to the control group. After the analysis of multivariate Logistic regression and variables screening, it was showed that times of balloon dilatation ≥ 3 ( OR＝1.725, 95% CI 1.211－2.358, P＝0.014) and high burden of thrombus ( OR＝1.821, 95% CI 1.322-2.511, P＜0.01) were the risk factors of SF or NR, while the application of GPⅡB/ⅢA receptor antagonist ( OR＝0.623, 95% CI 0.382-0.855, P＝0.012) was the protective factor of SF or NR. Conclusions Multiple balloon dilatation and high burden of thrombus increased the risk of SF or NR, while the application of GPⅡB/ⅢA receptor antagonists could inhibit the occurrence of SF or NR.

Objective: To explore the clinical effect of traditional Chinese medicine (TCM) syndrome differentiation in the treatment of pneumoconiosis. Methods: We selected 160 pneumoconiosis patients who were hospitalized in our hospital from July 2015 to July 2016. 102 patients were divided into experimental groups, and the other 58 patients were assigned to the control group. These patients were randomly assigned. The control group was given routine treatment, while the experimental group received conventional treatment combined with TCM syndrome differentiation. We rated patients' quality of life using the SF-36 Quality of Life Scale. C-reactive protein levels in both groups before and after treatment were detected by ELISA. Furthermore, we detected the expression levels of IL-6 mRNA and TGF-β mRNA in serum before and after treatment by RT-PCR.The analysis was performed with SPSS19.0 software. The normal distribution measurement data was expressed by Mean±SD, and the t-test was used for statistical analysis. Non-normal distribution measurement data were expressed as median(M) and interquartile range (P₂₅, P₇₅), and non-parametric test was used for statistical analysis. Results: Compared with the control group, the readmission rate in the experimental group decreased within 3 months; The SF-36 quality of life score results of the two groups showed a statistically significant difference in BP, VT and RE (P<0.05);The levelofCRPdecreasedsignificantlyafter treatment in bothgroups,and thedifferencewasstatistically significant (P<0.05).Comparedwith thecontrolgroup, the levelsofIL-6mRNAandTGF-β1mRNA alsodecreased (P<0.05). Conclusion TCM syndromedifferentiation and treatmentofpneumoconiosis can effectively improve the patient's condition and life quality. We predict that it may inhibit the progression of pulmonary fibrosis in pneumoconiosis.

Objective: To explore the mediating effects of self-focused attention between social anxiety and interpersonal needs. Methods: Totally 467 college students [159 males and 221 females, mean age (21 ±2)] were assessed with the Social Anxiety Scale (SAS), Self-Focused Attention Scale (SFAS) and Interpersonal Needs Questionnaire (INQ ). The bootstrap method was used to test the mediating effect Results: The SFAS and INQ scores were higher in female students than in males (Ps <0.01). The scores of SAS, SFAS, and INQ were positively correlated each other (r = 0.20 - 0.90, Ps < 0.01). Self-focused attention has a full mediating effect between social anxiety and interpersonal needs, and the 95％ confidence interval was (0.34, 0.59). Conclusion: It suggests that the effect of interpersonal needs on social anxiety may be achieved through self-focused attention in college students. Reducing the level of self-focused attention may be an important way to alleviate social anxiety among college students.

Abstract In recent decades, there is a decreasing trend in physical activity, which might be associated with decline in physical and mental health among children and adolescents in China. The outbreak and spread of the COVID-19 further aggravated this trend. Under the background of normalized epidemic prevention and control, in order to deeply understand the relationship between physical activity and physical and mental health of children and adolescents, this study sorted out relevant domestic and foreign literatures, and analyzed the effects of physical activity on children and adolescents health and fitness. The positive effects of physical activity, cognition, and mental health were found to be significantly different in the type, intensity, and time of physical activity in the related health effects.

Objective To analyze the clinical and imaging characteristics of pediatric neuromyelitis optica spectrum disorders(NMOSD)in children. Methods The clinical data,imaging manifestations and follow - up data of 16 NMOSD patients at Department of Pediatric Neurology,Shandong Provincial Hospital Affiliated to Shandong Univer-sity between July 2013 and September 2017 were respectively analyzed. Results In 16 patients,initial presentations included optica neuritis(ON)in 5 cases,longitudinally extensive transverse myelitis(LETM)in 6 cases,and among them there were 2 cases with acute disseminated encephalomyelitis and 3 cases with both ON and LETM. Eleven cases received aquaporin - 4(AQP4)antibody examination and 4 cases were found seropositive. One case out of 7 detected cases was found AQP4 antibody positive in cerebrospinal fluid. Eleven cases received optica magnetic resonance imaging (MRI),and 8 cases were found abnormal signals in optic nerve and optica chiasma. The spinal cord MRI showed 13 ca-ses with LETM manifestations,and abnormal signals were found in vertebral segments(5 - 13),and among them 1 case had cervical cord,3 cases were thoracic cord and 9 cases were both of the above. Lesions in the cervical cord in 2 cases were extended upward to the medulla. Fifteen cases received brain MRI and all of them had brain lesions,which were mainly involved in the central and subcortical white matter,thalamus,corpus callosum,brainstem,the junction of spinal cord and medulla,cerebellum,and so on. All patients received treatment for acute attacks with high - dose Methylpred-nisolone and/ or gamma globulin and got obvious relief. Two cases with recurrent ON received treatment of Rituximab and their vision became improved. Fifteen patients were followed up,and 2 cases had limb disorders and 4 cases had visual impairment,other patients had no clinical symptoms. Conclusions Pediatric NMOSD has a diverse clinical pre-sentation at the onset disease. Those who are initial diagnosed acute myelitis,ON and acute disseminated encephalomye-litis should be considered the possibility of NMOSD. Antibody to AQP4 testing can assist the diagnosis. The typical ima-ging characters of NMOSD children are abnormal signals in the high expression area of AQP4. Intracranial lesions are more common in children. The acute treatment includes the high - dose Methylprednisolone and gamma globulin. Rituximab can be used for the recurrent patients.

The TEA domain (TEAD) family proteins (TEAD1‒4) are essential transcription factors that control cell differentiation and organ size in the Hippo pathway. Although the sequences and structures of TEAD family proteins are highly conserved, each TEAD isoform has unique physiological and pathological functions. Therefore, the development and discovery of subtype selective inhibitors for TEAD protein will provide important chemical probes for the TEAD-related function studies in development and diseases. Here, we identified a novel TEAD1/3 covalent inhibitor (DC-TEADin1072) with biochemical IC
