OBJECTIVE:To provide reference for improving propaganda level and effect of rational drug use. METHODS:Questionnaire survey was designed to investigate the recognition,attitude and demand of consumers in retail pharmacies,students in parts of pharmaceutical universities and their parents and patients in parts of hospitals in more than 10 provinces(autonomous re-gions and municipalities)for propaganda of rational drug use,and the results were statistically significant. RESULTS:The question-naires ranged from 100 to 2 000 in each province (autonomous region and municipality),and totally 11 700 questionnaires were sent out,11 490 were received with recovery of 98.2%;10 980 were effectively received with effective recovery of 95.6%. 78.4%respondents heard of the concept of rational drug use,proportion of young and middle-aged people in 18-44 years old was signifi-cantly higher than other age group,the proportion was significantly increased by the improvement of education,and the proportion of people closer to the city was higher(P<0.001);the respondents who can fully understand the content of the propaganda account-ed for 22.7%,while higher education held higher proportion on“fully understand”,and people closer to the city held higher pro-portion on“fully understand”and“partially understand”(P<0.001);only 9.5% respondents could fully trust propaganda activity, proportion of choosing“partially trust”was generally increased by the improvement of education(P<0.001);and 69.1% respon-dents hoped to obtain relevant knowledge,people who had more purchase frequencies showed stronger willing(P<0.001);the top 3 preferences of respondents for propaganda forms were“face to face guidance from physicians and pharmacists”,“reading drug in-structions”and“reading professional books”. CONCLUSIONS:With insufficient recognition on rational use of drugs,coverage of propaganda about rational drug use needs further expand,public understanding of propaganda contents about rational drug use is fairly limited and people’s trust level towards propaganda is not high,but the public has strong desires to obtain the knowledge about rational drug use. Therefore,various means should be adopted to improve the effects on propaganda of rational drug use.

Objective To investigate certain risk factors for and their impact on abnormal liver function in middle-aged and elderly adults.Methods A case-control study was constructed based on the SAGE cohort of 8642 registered residents aged 50 years or over in Shanghai.Of them,137 individuals with abnormal liver function,defined as aspartate transaminase (AST)> 40 U/L or alanine aminotransferase (ALT)> 40 U/L,were randomly selected as the observation group,while 411 healthy controls were 3 ∶ 1 matched with the cases in the observation group by gender and age (1 year).Face-to-face administered questionnaires and physical examinations were conducted and serum samples were tested for ALT,AST,glucose (GLU),total cholesterol (TC),triglycreide (TG),hepatitis B surface antigen (HbsAg) and anti-hepatitis C virus antibody (anti-HCV Ab).Chi square test and rank sum test were used for single factor analysis,and logistic regression analysis was used for multiple factors.Results The prevalence of HBsAg positive patients was 12.4 % (68/548) Univariate analysis showed that hepatitis virus infection and body mass index (BMI) were associated with abnormal liver function (both P<0.000).Multivariate logistic regression analysis showed that hepatitis virus infection (OR=1.85,95% CI:1.04 3.29,P-0.036) and obesity (OR=3.60,95%CI:1.92-6.73,P<0.001) increased the risk of abnormal liver function,whereas chronic medication (OR=0.51,95% CI:0.32-0.80,P =0.004) decreased the risk of abnormal liver function.Conclusions Among the study population,hepatitis virus infection and obesity are risk factors for abnormal liver function in middle-aged and elderly people.After adjustment for potential confounders,chronic medication is negatively correlated with abnormal liver function and may be a protective factor for liver function.

Objective To construct PES1 shRNA stable expression cell lines in tongue squamous cell carcinoma ( TSCC) cells and to study the effect of knockdown of PES 1 on the growth of TSCC cells .Methods Recombinant lentivirus carrying PES1 shRNA was packaged and obtained in 293T cells.TSCC cells (Tca8113, SCC6 and SCC15) were infected with the lentivirus and selected for stable cells .PES1 expression was identified by Western blot .The effect of inhibition of PES1 on the growth and cell cycle of TSCC cells was detected by growth curve and flow cytometry .Results TSCC cells stably expressing PES1 shRNA were constructed.Knockdown of PES1 inhibited cell proliferation and induced cell cycle ar-rest at G0/G1 phase.Knockdown of PES1 inhibited expression of cyclin D1 in TSCC cells.Conclusion Inhibition of PES1 results in reduced cell proliferation , cell cycle arrest at G 0/G1 phase and reduction of cyclin D 1 expression in TSCC cells . PES1 may be a target for TSCC gene therapy .

Objective:To investigate the quality control of magnetic resonance enterography(MRE)in the diagnosis of intestine diseases,and analyze the factors that affected the imaging quality of MRE,and enhance the imaging quality of MRE through adopted the measures of quality control.Methods:The documents of MRE examinations of 167 patients with intestinal disease who admitted to the 900th Hospital of People's Liberation Army Joint Service Support Force from May 2018 to March 2023 were retrospectively analyzed.The image qualities of all patients were evaluated after they completed clinical and image examinations.The reasons that image quality could not meet the requirement of diagnosis were analyzed.And then,the measures of quality control were proposed.Results:In 167 patients with intestinal disease,the MRE images of 153 patients(91.62%)could meet the requirement of diagnosis.In 14 patients(8.38%)whose MRE images could not meet the requirement of diagnosis,the reason of 3 cases(1.80%)was poor respiratory coordination,and that of 2 cases(1.20%)was there were more severe magnetic sensitive artifacts in images,and that of 1 case(0.60%)was severe intestinal peristalsis leaded to blurred images,and that of 2 cases(1.20%)was the flow void effect from intestinal peristalsis inside of intestinal cavity could not meet the requirement of diagnosis,and that of 4 cases(2.40%)was the intestinal tube without incomplete dilation caused by poor oral filling contrast agent,and that of 2 cases(1.20%)was many residues in intestine due to poor preparation for intestine.Aimed at the factors that MRE images could not meet requirement of diagnosis,we proposed the following quality control measures:①the biphasic contrast agents with favorable safety,without severe adverse reactions,which can fully dilate intestinal cavity,should be selected.②we should do well for the dilation of intestinal tube,and inhibit the intestinal peristalsis and conduct respiratory training.③we should conduct scan with wide field at coronal site,so as to display panorama image of intestine.④The scans of conventionally anatomical sequence and functional imaging sequence on axis position were performed on lesions.Conclusion:MRE technique should choose appropriate contrast agent in the quality control of the diagnosis of intestine diseases,and do well the preparation for patients before examination.Using intraluminal contrast agents,conducting intestinal dilation and optimal imaging technique are essential for obtaining intestinal MRE images with high quality.
