Gastric cancer(GC)is one of the most common gastrointestinal tumors.As a newly discovered type of non-coding RNAs,transfer RNA(tRNA)-derived small RNAs(tsRNAs)play a dual biological role in cancer.Our previous studies have demonstrated the potential of tRF-23-Q99P9P9NDD as a diagnostic and prognostic biomarker for GC.In this work,we confirmed for the first time that tRF-23-Q99P9P9NDD can promote the proliferation,migration,and invasion of GC cells in vitro.The dual luciferase reporter gene assay confirmed that tRF-23-Q99P9P9NDD could bind to the 3'untranslated region(UTR)site of acyl-coenzyme A dehydrogenase short/branched chain(ACADSB).In addition,ACADSB could rescue the effect of tRF-23-Q99P9P9NDD on GC cells.Next,we used Gene Ontology(GO),the Kyoto Encyclopedia of Genes and Genomes(KEGG),and Gene Set Enrichment Analysis(GSEA)to find that downregulated ACADSB in GC may promote lipid accumulation by inhibiting fatty acid catabolism and ferroptosis.Finally,we verified the correlation between ACADSB and 12 ferroptosis genes at the transcriptional level,as well as the changes in reactive oxygen species(ROS)levels by flow cytometry.In summary,this study proposes that tRF-23-Q99P9P9NDD may affect GC lipid metabolism and ferroptosis by targeting ACADSB,thereby promoting GC progression.It provides a theoretical basis for the diagnostic and prognostic monitoring value of GC and opens up new possibilities for treatment.

Objective:To explore the impact of PM 2.5 concentration in Shanghai on the incidence of allergic rhinitis（AR） in the population, and provide strategies for early warning and prevention of AR. Methods:Collect daily average concentrations of atmospheric pollutants monitored in Shanghai from January 1, 2017 to December 31, 2019, and clinical data of AR patients from five hospitals in Shanghai during the same period. We used a time-series analysis additive Poisson regression model to analyze the correlation between PM 2.5 levels and outpatient attendance for AR patients. Results:During the study period, a total of 56 500 AR patients were included, and the daily average concentration of PM 2.5 was（35.28±23.07）μg/m³. There is a correlation between the concentration of PM 2.5 and the number of outpatient attendance for AR cases. There is a positive correlation between the daily average number of outpatient for AR and levels of PM 2.5 air pollution（（P<0.05）） . We found that every 10 μg/m³ increase in PM 2.5, the impact of on the number of AR visits was statistically significant on the same day, the first day behind, and the second day behind, with the strongest impact being the exposure on the same day. Every 10 μg/m³ increases in PM 2.5, the number of outpatient visits increased by 0.526% on the same day（95%CI 1.000 50-1.010 04）. Conclusion:The atmospheric PM 2.5 concentration in Shanghai is positively correlated with the number of outpatient for AR, and PM 2.5 exposure is an independent factor in the onset of AR. This provides an important theoretical basis for AR.

Objective:To compare serum procalcitonin and fibrinogen degradation product levels between type 2 diabetes mellitus patients with Escherichia coli bloodstream and urinary tract infections. Methods:The clinical data of 82 type 2 diabetes mellitus patients with Escherichia coli infections who received treatment between December 2014 and December 2019 in the First Affiliated Hospital of Datong University (The Fifth People's Hospital of Datong) were retrospectively analyzed. These patients were assigned to bloodstream infection ( n = 40) and urinary tract infection ( n = 42) according to the way of Escherichia coli infection. Serum procalcitonin and fibrinogen degradation product levels, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, C-reactive protein, white blood cell count, D-Dimer level, antithrombin III activity, and electrolytes were determined and compared between the two groups. Correlation between procalcitonin and other variables was analyzed. Multiple linear regression analysis was performed with procalcitonin level as a dependent variable and other relevant indexes as independent variables. Results:Body temperature, white blood cell count, neutrophil count, monocyte count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, procalcitonin level, C-reactive protein level, fibrinogen degradation product level, and D-Dimer level in the bloodstream injection group were (39.49 ± 0.64) ℃, (14.92 ± 11.78) × 10 9/L, (13.39 ± 11.60) × 10 9/L, (0.72 ± 0.36) ×10 9/L, (14.86 ± 10.52), (199.15 ± 160.69), (22.81 ± 17.86) μg/L, (133.44 ± 63.63) mg/L, (49.71 ± 41.44) mg/L, (16.56 ± 12.20) mg/L, respectively, which were significantly higher than those in the urinary tract infection group [(37.12 ± 1.20) ℃, (9.04 ± 3.95) × 10 9/L, (6.25 ± 4.02) × 10 9/L, (0.42 ± 0.29) × 10 9/L, (3.67 ± 3.34), (120.01 ± 44.08), (4.46 ± 8.69) μg/L, (39.22 ± 22.16) mg/L, (3.81 ± 3.41) mg/L, (0.84 ± 0.75) mg/L), t = 7.356, 2.578, 3.162, 2.958, 5.538, 2.591, 2.810, 4.825, 2.902, 2.375, all P < 0.05]. Platelet count, lymphocyte count, blood sodium level and antithrombin Ⅲ activity in the bloodstream infection group were (167.50 ± 104.93) × 10 9/L, (1.06 ± 0.58) × 10 9/L, (130.89 ± 6.50) mmol/L, (57.88 ± 16.28)% , which were significantly lower than those in the urinary tract infection group [(239.40 ± 82.52)× 10 9/L, (2.14 ± 0.71) × 10 9/L, (138.46 ± 5.96) mmol/L, (90.11 ± 8.90)%, t = -2.853, -6.313, -4.046, -7.350, all P < 0.05]. Correlation analysis revealed that serum procalcitonin level was positively correlated with body temperature ( r = 0.387), white blood cell count ( r = 0.355), neutrophil count ( r = 0.368), C-reactive protein ( r = 0.605), fibrinogen degradation product level ( r = 0.616), D-Dimer level ( r = 0.486) (all P < 0.05), and it was negatively correlated with sodium level ( r = -0.319) and antithrombin Ⅲ activity ( r = -0.465) (both P < 0.05). Multiple linear regression analysis results revealed that fibrinogen degradation product level and body temperature were greatly correlated with procalcitonin level. Conclusion:Inflammatory indicators procalcitonin level, body temperature, white blood cell count, neutrophil count, C-reactive protein, fibrinogen degradation product level and D-Dimer level were remarkably higher in type 2 diabetes mellitus patients with Escherichia coli bloodstream infection than those in type 2 diabetes mellitus patients with Escherichia coli urinary tract infection. Procalcitonin level was greatly correlated with body temperature and fibrinogen degradation product level.

Objective:To evaluate the effect of web-based problem-based learning software on the Clinical Medicine PBL Comprehensive Course. Methods:Thirty-eight students from the pilot class of undergraduate excellent doctors in clinical medicine were selected as the research objects. Based on the test scores of web-based problem-based learning software before the start of the course, the improvement of scores after passing the training of the Clinical Medicine PBL Comprehensive Course were compared, and the students' clinical thinking were quantitatively evaluated. Results:After all students completed the course, their abilities of expression and communication, teamwork and cooperation, problem analysis and clinical reasoning, and knowledge information management of the students increased steadily with the increase in the number of cases, but it was statistically significant after two PBL case trainings ( P<0.05). Learning intentions and attitudes scored the highest in the second PBL case (acute myocardial infarction), with statistical differences ( P<0.05). After training through the PBL course, diagnostic performance, clinical thinking, treatment scores, and overall performance scores of the students were significantly increased than before, with statistical significance ( P<0.05). The scores of case report writing and knowledge acquisition were not obviously improved. Conclusion:The combination of formative evaluation and web-based problem-based learning software can better evaluate the teaching effect and help students to understand their own shortcomings.

Although cardiovascular disease (CVD) is a major health challenge in Malaysia, many Malaysians are unaware of their CVD risk. The measurement of biomarkers in the general population may help to identify at-risk individuals before the onset of symptomatic CVD. The aim of this community health screening project was to determine the distribution of high-sensitivity troponin I (hsTnI) and other biomarkers of CVD risk in the general population of Johor, Malaysia. A sampling of self-declared healthy volunteers was conducted during the 2016 Kembara Mahkota community event in Johor. Levels of hsTnI, B-type natriuretic peptide (BNP) and homocysteine (HCY) were analyzed using the ARCHITECT immunoassay and clinical chemistry platforms utilizing fresh venous blood samples. Based on previous data, biomarker levels indicative of high risk were >10 and >12 ng/mL for hsTnI in women and men, respectively, BNP >50 pg/mL in the overall population, and HCY >13.6 µmol/L in women and >16.2 µmol/L in men. A total of 2744 volunteers participated in biomarker testing. Biomarker measurements showed that up to 10% of participants had moderate or high CVD risk based on hsTnI, approximately 2% were above the BNP threshold and >50% of subjects were above the HCY threshold. General population biomarker testing shows distribution of biomarker levels that may be indicative of CVD risk or the presence of disease and suggests that biomarker-guided risk strategies should be more widely implemented to determine the impact they would have on early detection and prevention of disease.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Objective To analyze iodine nutrition and its correlation with thyroid function in pregnant women.Methods A total of 295 pregnant women were enrolled from Jun.to Oct.2016,and detected for serum levels of thyroid stimulating hormone(TSH),free thyroxine(FT4) and thyroid-peroxidase antibody(TPOAb) by using electrochemiluminescence analysis,and for urinary iodine concentration(UIC) by cold digestion method according to iodine catalytic effect of arsenic-cerium.Results The median of UIC was 174.90 μg/L.The prevalence of iodine deficiency and iodine excess were 40.00% and 7.12% respectively.The prevalence of TPOAb positivity and thyroid dysfunction in the iodine deficiency group and iodine excess group were significantly higher than those of iodine proper group(P<0.05).The levels of TSH and FT4 of iodine excess group were significantly higher than those of iodine proper group(P<0.05).Conclusion The abnormality of iodine nutrition could be common in pregnant women.Monitoring of UIC and thyroid hormones should be highlighted.

[Objective]To compare and contrast the dosimetry between Tomo planning and BrainLab planning for lung metasta-ses in stereotactic body radiation therapy(SBRT).[Methods]Four Patients with one,two,three and four metastases were selected. The PTV is 2.89 ± 1.15 cm3. Two plannings with total dose of 50 Gy to cover 95% of PTV ,5 Gy/Fraction and 10 fractions were designed using Tomo planning system and BrainLab planning system respectively. The DVH curves of spinal cord ,both lungs and normal tissue were compared. The conformity index andhomogeneityindex were analyzed as well.[Results]The homogeneity index (HI)and conformity index(CI)of the targets in Tomo planning system were 1.0314 ± 0.0700 and 0.687 ± 0.075,respectively. In BrainLab planning system the HI and CI of the targets were 1.0764 ± 0.1241 and 0.571 ± 0.042,respectively. To HI the P value in T test was less than 0.01 and the HI was better in Tomo than BrainLab and so was CI. The dose to spinal cord was higher in BrainLab planning system than that in Tomo. The dose to nomal tissue and both lungs were not different in the two planning systems and V20 of lung is as small as 10%.[Conclusions]For small volume lung metastases which longest diameter were less than 4 cm,the tomotherapy should be better choice.
