OBJECTIVE To investigate the current usage status of OTC drug among residents in Inner Mongolia Autonomous Region, and to provide evidence for the science popularization of rational drug use. METHODS By approximate random sampling, the questionnaire survey was conducted with the mini-apps Questionnaire Star among the residents aged 19 and above from 7 league or cities of Inner Mongolia Autonomous Region, in order to investigate the current situation of OTC drug use in the region. RESULTS A total of 611 people filled in the questionnaire, and 571 people filled in the questionnaire effectively, with an effective filling rate of 93.45%. According to the results, 18.7% of residents said they did not understand the concept of OTC drugs, 36.1% of residents said they did not know the OTC drug label, and 65.3% of residents did not know the difference between class A and B OTC drugs in terms of OTC drug awareness. And there were statistically significant differences in the scores of OTC drug awareness among different genders, education levels, monthly income and places of residence (P<0.05). When choosing OTC drugs, 23.5% of residents still believed in advertisements or friends’ recommendations; 14.5% of the residents did not read the drug instructions carefully before taking drugs. In terms of drug risk, 5.1% of residents had long-term use of OTC drugs; 8.6% of residents reported taking three or more OTC drugs; 2.1% of residents often added other drugs with the same effect or increased the dosage by themselves. They took traditional Chinese medicine, Mongolian medicine and other preparations while taking OTC drugs, accounting for 19.6%, 22.6% and 13.0% respectively. CONCLUSIONS Residents in Inner Mongolia have low awareness of OTC drugs, and their habits of drug use need to be improved. Repeated drug use and overdose drug use are serious, it is necessary to strengthen the publicity and popularization of rational use of OTC drugs.

Cyclooxygenases play a vital role in inflammation and are responsible for the production of prostaglandins. Two cyclooxygenases are described, the constitutive cyclooxygenase-1 and the inducible cyclooxygenase-2, for which the target inhibitors are the non-steroidal anti-inflammatory drugs (NSAIDs). Prostaglandins are a class of lipid compounds that mediate acute and chronic inflammation. NSAIDs are the most frequent choices for treatment of inflammation. Nevertheless, currently used anti-inflammatory drugs have become associated with a variety of adverse effects which lead to diminished output even market withdrawal. Recently, more studies have been carried out on searching novel selective COX-2 inhibitors with safety profiles. In this review, we highlight the various structural classes of organic and natural scaffolds with efficient COX-2 inhibitory activity reported during 2011-2021. It will be valuable for pharmaceutical scientists to read up on the current chemicals to pave the way for subsequent research.

Objective@#To estimate the transmission capacity of influenza clustering in schools and nurseries, and to evaluate the effect of suspension measures, providing a basis for formulating disease management strategies and control measures.@*Methods@#The SEIAR dynamics model was used to simulate the epidemic data, calculating the basic regeneration coefficient R 0 of the epidemic to evaluate the epidemic transmission capacity, and calculating the cumulative incidence rate of the epidemic to evaluate the prevention and control effect of the suspension measures.@*Results@#The basic regeneration coefficient R 0 was 8.44(8.01,8.89) without intervention. There were statistically significant differences in R 0 of influenza epidemic among different types of school(F=9.52, P<0.01). The R 0 of influenza epidemic in primary and secondary schools were higher than that in nurseries(P<0.05). R 0 of influenza A was higher than that of influenza B(t=2.71, P<0.01). R 0 of influenza A(H3) was higher than of influenza B(Victoria)(P<0.05). The cumulative incidence of the outbreaks which were suspended for 4 days and 7 days was significantly lower than that in the non-suspensions(P<0.05). However, there was no significant difference in the cumulative incidence of the outbreaks between the 4-day suspension and the 7-day suspension(P>0.05).@*Conclusion@#Transmission capacity of school-based influenza epidemic is high, especially among primary and secondary schools. When the epidemic situation of infected class meets the suspension standard, it is recommended to suspend classes for 4 days.

Objective To explore the expression and significance of miR-21 in patients with primary gout. Methods The patients were divided into 4 groups: 35 acute gout patients (AG), 50 intermittent gout patients (IG), 25 chronic gout patients (CG) and 39 healthy patients. Their peripheral blood were collected and laboratory indexes were recorded. The expression of miR-21 and Nod-like receptor pyrin domain-containing protein 3 (NLRP3) mRNA in the peripheral blood mononuclear cells (PBMCs) was detected by real-time quantitative polymerase chain reaction (RT-qPCR). The blood and clinical data of another 5 healthy volunteers were collected, their peripheral blood was stimulated with 100 μg/ml monosodium urate (MSU) for 1 hour, pho-sphate buffer (PBS) was used as controls, then the expression of microRNA (miR)-21, NLRP3, interleukin (IL)-1β mRNA was detected by RT-qPCR. Rank sum test and spearman correlation analysis were used for data analysis. Results In primary gout patients, the expression of miR-21 in AG [12 ×10-4 (8.0 ×10-4)], IG [9.4 ×10-4 (6.9 ×10-4)], CG [7.3 ×10-4 (5.6 ×10-4)] was significantly higher than that in healthy control group [1.0×10-4(2.0×10-4)] (Z=9.83, P=0.02], while the expression of NLRP3 in AG[0.0444(0.0233)], IG[0.0581(0.0326)], CG[0.0314(0.0198)] was significantly lower than that in healthy control group [0.0886(0.0359)] (Z=13.82, P<0.01). In the primary gout of IG group, the expression of miR-21 was positively correlated with NLRP3 mRNA (r=0.449, P=0.016). After stimulated by 100 μg/ml MSU, the expression of miR-21 of the stimulated group [8.78×10-4(14×10-4)] was higher than that in the control group [6.25×10-4(6×10-4)](Z=-2.203, P<0.05), and the expression of IL-1βin stimulated group [3.06(2.00)] was higher than that in the control group [2.64 (1.22] (Z=-2.203, P<0.05). The level of miR-21 in patients with primary gout was positively correlated with the level of uric acid (UA), glutamic oxaloacetic transaminase (AST) and glutamic pyruvic transaminase (ALT) (r=0.473, 0.639, 0.487, P<0.05). Conclusion The increase of miR-21 in patients with primary gout may be involved in the inflammatory reaction of gout.

Objective@#To investigate the expression and clinical significance of circDLGAP4 from peripheral blood in coronary heart disease (CAD). @*Methods@#The relative expression level of circDLGAP4 in peripheral blood leukocytes (PBLs) from 142 CAD patients and 169 healthy controls were detected by real-time PCR. Logistic regression, Spearman correlation and multivariate regression analysis were used to investigate the correlation of circDLGAP4 with CAD. THP-1 macrophages were treated with oxidized low density lipoprotein (ox-LDL) to construct an atherosclerotic foam cell model. The levels of circDLGAP4 mRNA were detected at different time points. @*Results@#The mRNA expression of circDLGAP4 in PBLs of CAD patients was significantly decreased compared with controls (P=0.019). With increased unit (2 -ΔCt ) of circDLGAP4 expression, the risk of CAD occurrence reduced by 41.6% (adjusted OR=0.584, 95% CI: 0.394-0.866, P=0.007). The expression of circDLGAP4 was negatively correlated with T2DM history (β=-0.182,P=0.030). The level of circDLGAP4 in ox-LDL-treated THP-1 macrophages was decreased in a time-dependent manner. @*Conclusion@#The expression of circDLGAP4 was significantly decreased in PBLs of CAD patients and THP-1 macrophages-derived foam cells, and might be a protective factor in the pathophysiology of CAD.
摘要
Objective@#To explore the relationship between HCM pathogenic gene mutations and clinical phenotypes by analyzing the prenatal diagnosis and genetic characteristics of a pregnant woman from a family with hypertrophic cardiomyopathy (HCM). @*Methods@#The clinical data of the proband and her family members was collected. The DNA was extracted from the peripheral blood, amniotic fluid cells and cultured amniotic fluid cells of proband. Next generation sequencing (NGS) was utilized for screening pathogenetic loci of the proband. The suspected mutation sequences of HCM pathogenic candidate genes MYH7 and MYBPC3 were directly sequenced after PCR. Pathogenicity prediction of amniotic fluid cells was performed by using genetic data and bioinformatics software, such as Mutation taster, PolyPhen-2 and ANTHEPROT. @*Results@#The sequencing results showed that heterozygous mutations of MYH7 c.1988G>A (p.Arg663His) and MYBPC3 c.151G>A (p.Ala51Thr) were found in the proband. The phenotype of her father was normal, and no abnormal mutations were detectable. Her mother also showed normal phenotype but carried MYBPC3 c.151G>A heterozygous mutation. Only MYH7 c.1988G>A heterozygous mutation was found in the fetus and no abnormal variation of MYBPC3 was showed. The prediction of mutation effect and analysis of protein structure and function revealed that the two missense mutations could affect the hydrophobicity and antigenicity of the protein. The genetic data demonstrated MYH7 c.1988G>A was defined as a pathogenic mutation. @*Conclusion@#MYH7 c.1988G>A should be a newly generated pathogenic mutation in the proband, or caused by reproductive chimerism of her parents. MYBPC3 c.151G>A mutation may promote the occurrence of HCM. Although the fetus only carries MYH7 c.1988G>A, her phenotype may still display as HCM.
