RÉSUMÉ

INTRODUCTION@#Observational studies have revealed an association between waist circumference (WC) and atrial fibrillation (AF). However, it is difficult to infer a causal relationship from observational studies because the observed associations could be confounded by unknown risk factors. Therefore, the causal role of WC in AF is unclear. This study was designed to investigate the causal association between WC and AF using a two-sample Mendelian randomization (MR) analysis.@*METHODS@#In our two-sample MR analysis, the genetic variation used as an instrumental variable for MR was acquired from a genome-wide association study (GWAS) of WC (42 single nucleotide polymorphisms with a genetic significance of P <5 × 10 -8 ). The data of WC (from the Genetic Investigation of ANthropometric Traits consortium, containing 232,101 participants) and the data of AF (from the European Bioinformatics Institute database, containing 55,114 AF cases and 482,295 controls) were used to assess the causal role of WC on AF. Three different approaches (inverse variance weighted [IVW], MR-Egger, and weighted median regression) were used to ensure that our results more reliable.@*RESULTS@#All three MR analyses provided evidence of a positive causal association between high WC and AF. High WC was suggested to increase the risk of AF based on the IVW method (odds ratio [OR] = 1.43, 95% confidence interval [CI], 1.30-1.58, P = 2.51 × 10 -13 ). The results of MR-Egger and weighted median regression exhibited similar trends (MR-Egger OR = 1.40 [95% CI, 1.08-1.81], P = 1.61 × 10 -2 ; weighted median OR = 1.39 [95% CI, 1.21-1.61], P = 1.62 × 10 -6 ). MR-Egger intercepts and funnel plots showed no directional pleiotropic effects between high WC and AF.@*CONCLUSIONS@#Our findings suggest that greater WC is associated with an increased risk of AF. Taking measures to reduce WC may help prevent the occurrence of AF.

RÉSUMÉ

OBJECTIVE To evaluate the clinical effectiveness and safety of domestic generic and imported original clopidogrel for antiplatelet therapy in patients with acute coronary syndrome (ACS). METHODS The clinical data of ACS patients in Nanjing Drum Tower Hospital of China Pharmaceutical University from January 2020 to June 2021 were retrospectively collected by using electronic medical record system, and the patients were divided into original drug group (321 cases) and generic drug group (328 cases) according to the drug use. Both groups were given dual antiplatelet therapy with clopidogrel and aspirin. The effectiveness and safety outcomes of the two groups were followed up for 12 months and compared, the related influential factors were analyzed. RESULTS Major adverse cardiovascular events (MACE) occurred in 16 and 22 patients in original drug group and generic drug group respectively, including nonfatal myocardial infarction (4 and 5 cases), stroke (2 and 4 cases), revascularization (8 and 3 cases), cardiovascular related death (2 and 4 cases), and all-cause death (4 and 6 cases). There were 12 and 7 patients with major bleeding events, 38 and 29 patients with minor bleeding events, and 33 and 21 patients with non-bleeding adverse events. There was no statistically significant difference in the cumulative incidence of related events (P values of Log-Rank tests were all greater than 0.05). Cox regression analysis showed that the use of generic clopidogrel did not increase the risk of MACE and major bleeding events in ACS patients [hazard ratio of 1.305 and 0.416, 95% confidence interval of (0.678, 2.512) and (0.155, 1.117), respectively, P>0.05], and the combination of proton pump inhibitors (PPI) could reduce the risk of major bleeding events [hazard ratio of 0.196, 95% confidence interval of (0.063, 0.611), P<0.05]. CONCLUSIONS Compared with imported original drug, domestic generic clopidogrel has similar clinical effectiveness and good safety. Combined use of PPI may be a beneficial factor to reduce the occurrence of major bleeding events in patients.

Objective:To investigate the clinical outcome after surgery and first 131I treatment in patients with moderate-risk papillary thyroid cancer (PTC), and analyze the relevant factors that affect the therapeutic effect. Methods:From January 2018 to April 2019, 135 patients (48 males, 87 females; age (42.7±11.1) years) with moderate-risk PTC in the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. According to the 2015 American Thyroid Association (ATA) guidelines, patients were divided into excellent response (ER) group, inderteriminate response (IDR) group, biochemical incomplete response (BIR) group and structural incomplete response (SIR) group, of which IDR, BIR, SIR were collectively referred to as the non-ER group. χ2 test and Mann-Whitney U test were used to compare the general clinical features between the ER and non-ER groups, and then multivariate logistic regression analysis was performed. The predicted value of pre-ablation stimulated thyroglobulin (ps-Tg) to ER was assessed by ROC curve analysis. Results:The treatment responses of 94 patients were ER, and those of 41 were non-ER. The differences in tumor size (0.80(0.50, 1.10) vs 1.00(0.55, 1.50) cm; U=1 491.50, P=0.036), the number of metastatic lymph nodes (3(2, 5) vs 4(2, 12); U=1 422.00, P=0.015), metastatic lymph node size (0.50(0.30, 0.65) vs 0.50(0.30, 1.45) cm; U=1 396.50, P=0.013), metastatic lymph node involvement rate (50%(30%, 70%) vs 60%(50%, 85%); U=1 441.50, P=0.024), metastatic lymph node location (central/lateral: 76/18 vs 24/17; χ2=7.40, P=0.007) and ps-Tg level (2.1(0.8, 5.3) vs 14.0(3.2, 35.2) μg/L; U=680.00, P<0.001) were statistically significant between the ER and non-ER groups. Multivariate logistic regression analysis showed that ps-Tg (odds ratio ( OR)=1.200, 95% CI: 1.107-1.302, P<0.001) was an independent factor influencing ER. The cut-off value of ps-Tg for predicting ER was 7.38 μg/L, with the sensitivity and specificity of 68.3%(28/41) and 87.2%(82/94) respectively. Conclusion:Moderate-risk PTC patients with smaller tumor size, fewer metastatic lymph nodes, lower metastatic lymph node involvement rate, metastatic lymph nodes in central area, smaller metastatic lymph node size, and ps-Tg<7.38 μg/L have better therapeutic effect after initial 131I treatment.

RÉSUMÉ

Chronic wounds in diabetes mellitus is a common complication of diabetes mellitus with complex pathogenesis and long recovery time. At present, there are many kinds of dressings for chronic wounds in diabetes, among which synthetic dressings have obvious therapeutic advantages. As an emerging biomaterial, hydrogel has obvious advantages over traditional dressings in terms of water absorption, air permeability, biocompatibility, drug loading ability, and continuous controlled drug release, and has attracted much attention in the repair of chronic wounds in diabetes mellitus. Common hydrogels have anti-inflammatory, antibacterial, antioxidant, tissue-promoting, and hypoglycemic effects. This paper systematically summarizes the progress in research on anti-inflammatory and antibacterial hydrogels in chronic diabetic wounds. Among them, according to different anti-inflammatory and antibacterial mechanisms and materials, common anti-inflammatory hydrogels can be divided into hydrogels loaded with anti-inflammatory drugs, hydrogels based on anti-inflammatory materials, and hydrogels loaded with biological components. Hydrogels can be classified into antibiotic-loaded hydrogels, antibacterial material-based hydrogels, and inorganic nanoparticles-loaded hydrogels. Anti-inflammatory and antibacterial hydrogels have achieved certain research results in the treatment of chronic diabetic wounds, but there are still some technical problems waiting for further improvement. Meanwhile, this paper discusses the prospect of the future development of hydrogels applied in chronic diabetic wounds, aiming to provide systematic theoretical support for the treatment of chronic diabetic wounds in the future.

OBJECTIVE:To study the potential mechanism of yam protein (DOT) in the prevention and treatment of diabetes-induced erectile dysfunction (DIED). METHODS :DIED model was induced by high-glucose and high-fat diet and intraperitoneal injection of streptozotocin (40 mg/kg). The experiment was set up in the normal control group (normal saline ), model group (normal saline ),DOT low-dose ,medium-dose and high-dose groups (0.3,0.6,0.9 mg/kg),sildenafil group (positive control ,4.4 mg/kg),with 9 rats in each group. In the stage of successful establishment of diabetes model and initiation of inducing DIED ,rats in each group were given relevant solution intragastrically ,once a day ,for consecutive 11 weeks. Body weight,fasting plasma glucose (FPG),the times and rate of penile erection ,fasting insulin (FINS),insulin resistance index (IR),the contents of endothelial nitric oxide synthase (eNOS)and cyclic guanosine monophosphate (cGMP)in penile cavernous tissue were determined so as to evaluate the intervention effects of DOT on DIED model rats. High-glucose damaged mice cavernous endothelial cells (MCECs)model was induced by 30 mmol/L glucose for 48 h,and then give DOT 125,250,500 μg/mL. The cell viability was detected so as to evaluate the effects of DOT on high-glucose damaged MCECs model. RNA-Seq mail:xingxin0902@163.com technology was adopted to screen the differentially expressed genes between normal MCECs and high-glucose damaged MCECs,high-glucose damaged MCECs and MCECs treated with 250 μg/mL DOT. Gene ontology(GO)function enrichment analysis and KEGG pathway enrichme nt analysis were performed for differentially expressed genes. The common differentially expressed genes between 2 groups were analyzed ,and mRNA expressions of six key genes were validated. RESULTS :Different doses of DOT could reverse the reduction of body weight ,the increase of FINS and IR ,the reduction of the times and rate of penile erection ,the decrease of eNOS and cGMP contents in penile cavernous tissue of DIED model rats ;above indexes of DIED model rats were reversed significantly after treated with high-dose of DOT(P<0.05 or P<0.01). 125,250,500 μg/L DOT could significantly improve the activity of high-glucose damaged MCECs (P<0.05 or P<0.01). RNA-Seq technology showed that compared with normal MCECs ,a total of 48 differentially expressed genes were found in high-glucose damaged MCECs. Compared with high-glucose damaged MCECs ,a total of 779 differentially expressed genes were found in MCECs treated with DOT. The differentially expressed genes of 2 groups were mainly cellular process in biological process annotation ,cellular part in cell component annotation and binding molecular function in molecular function annotation ,which were mainly enriched in extracellular matrix receptor interaction pathway ,mismatch repair pathway , phosphatidylinositol 3 kinase-protein kinase B (PI3K-Akt)signal pathway and so on. Among differentially expressed genes of 2 groups,13 common differentially expressed genes such as Aldh1a1,Abcc5,Tac1 were found. DOT could significantly reverse the expression of the above common differentially expressed genes in high-glucose damaged MCECs. After validation ,DOT could significantly reverse the mRNA expression of TGF-β3,Txnip,Aldh1a1,Loxl1,Mt1 and Mt2 in high-glucose damaged MCECs. CONCLUSIONS:DOT could improve the symptom of DIED model rats ,the mechanism of which may be related to biological pathway of inhibiting fibrosis and reducing oxidative stress ,so as to improve the endothelial function of cavernous body.

The interview contents were coded and analyzed, and the statistical methods of t test and rank sum test of two independent samples were used to screen competency characteristics and construct the competence model of assistant general practitioners.Results:The total classification consistency and the total coding reliability coefficient was respectively 0.79, 0.87. 59 competency characteristics of assistant general practitioners were obtained including 3 differentiated competency characteristics "Understanding the medical and health system and related policies", "Critical thinking skills" and "General practitioner clinical thinking" and 10 baseline competency characteristics. There was no statistically significant difference between the average performance group and the superior performance group in the total frequency of competency [(29.4±12.7) times to (23.4±7.0) times, t=1.27, P=0.22]. Conclusion:The preliminary competency characteristics of assistant general practitioners have good reliability and can provide references for further exploration of the competency model.

RÉSUMÉ

Salmonella enterica serovar Enteritidis (SE) is one of the most important zoonotic pathogens that cause enteritis and systemic infection in animals and human. Understanding invasive capacities of SE isolates is of vital importance to elucidate pathogenesis of Salmonella infection. To improve the throughput capacity and repeatability of classical gentamicin protection assay (GPA), a modified PGA was developed by taking high-throughput advantage of 96-well cell plates and multichannel pipettes. In addition, drop plate technique rather than spread plate method was applied in the modified GPA protocol for bacterial enumeration. The modified GPA protocol was evaluated by phenotyping intracellular replication of a high virulent and a low virulent SE isolates, JL228 and LN248, in a phagocytic cell line RAW264.7. The protocol was then applied in invasive phenotype determination of 16 SE strains to non-phagocytes (HT-29) and the intracellular replication of 43 SE strains to phagocytes (RAW264.7). Significant lower intra-group and inter-group coefficient of variations of the modified GPA was observed, implying good repeatability and reproducibility over traditional protocol. Further, replication phenotypes were also correlated with those from direct observation by confocal microscopy. Collectively, the improved GPA protocol had advantages of high throughput capacity, good repeatability and reliability, it was also noticed that the protocol also represented a fast and labor-saving alternative scheme for the invasive phenotype determination of Salmonella Enteritidis, and providing reliable phenotype profiles for Salmonella-host interplay interpretation.

RÉSUMÉ

Objective:To investigate and analyze the somatic symptom disorder, anxiety and depression in patients with myocardial bridge.Methods:A total of 276 patients with myocardial bridge diagnosed by coronary angiography (CAG) were enrolled in the department of cardiology of Renji hospital in Shanghai from June to December in 2016. There were 151 cases of simple myocardial bridge (no coronary stenosis or coronary artery stenosis <30%) and 125 cases of complex myocardial bridge (combined with coronary stenosis >30%). A total of 1067 patients with myocardial bridge without coronary angiography were collected at the same time. Self-rating somatic symptom scale (SSS), generalized anxiety disorder (GAD-7) and patient health questionnaire (PHQ -9) were given to these patients during hospitalization. At the same time, somatic symptoms disorder and anxiety and depression in the myocardial bridge group and non-myocardial bridge group were compared.Results:The prevalence of somatic symptom disorder in patients with myocardial bridge was higher than that in non-myocardial bridge patients (35.86% vs 28.30%, P<0.05). There was significant correlation between somatic symptom disorder and depression and anxiety, with correlation coefficients of 0.629 and 0.565, respectively. The prevalence of depression and anxiety in myocardial bridge patients was higher than that in non-myocardial bridge patients (depression: 23.91% vs 22.11%. P=0.467; anxiety: 17.02% vs 14.15%, P=0.22), but there was no statistical difference. For male patients or female patients, the prevalence of somatic symptom disorder, depression and anxiety in the simple myocardial bridge patients were higher than those in the complex myocardial bridge patients, but there was no statistical difference. The most common non-specific somatic symptoms disorder in patients with myocardial bridge were fatigue (64.5%), followed by sleep disorders (63.8%) and decreased attention (63.0%). Conclusion:The somatic symptom disorder in patients with myocardial bridge is significantly higher than that in non-myocardial bridge group. Especially for patients with myocardial bridge with non-specific somatic symptoms, early identification of somatic symptoms disorder of myocardial bridge patients will be beneficial to proper clinical invitation.

RÉSUMÉ

OBJECTIVE To study the relationship of the expression of PLOD2 protein in laryngeal carcinoma and the clinicopathological features of patients. METHODS The expression of PLOD2 in paraffin-embedded specimens of 114 patients with laryngeal carcinoma was detected by immunohistochemistry. The relationship between the expression of PLOD2 and clinicopathological features was analyzed by χ2 t est, s urvival a nalysis b y K aplan-Meier method, and multivariate analysis of Cox proportional hazard model. The fresh frozen specimens of 8 patients randomly selected from the patients were detected by realtime quantitative polymerase chain reaction and Western blotting for the expression of PLOD2 in tumor tissues and adjacent normal tissues. RESULTS PLOD2 protein was associated w ith c linical s tage a nd T s tage(P <0.05). The expression level of PLOD2 protein in laryngeal squamous cell carcinoma was higher than that in adjacent normal tissue(P <0.05). Kaplan-Meier survival analysis showed that low expression of PLOD2 was associated with patient survival rate(χ2=12.484, P <0.001). Multivariate Cox regression analysis showed that PLOD2 protein expression and M stage were independent risk factors for laryngeal cancer growth (P value, both <0.05). CONCLUSION The level of POLD2 protein expression was positively correlated with clinical stage and T stage. PLOD2 protein is an independent risk factor for the growth of laryngeal cancer. The higher the expression of PLOD2 protein, the lower the prognosis of patients. PLOD2 protein expression may play an important role in the growth and prognosis of laryngeal cancer, and may be a new molecular marker for judging the growth and prognosis of laryngeal cancer.
