简介:AbstractChoosing the appropriate antibiotics to treat bacterial infections has grown more challenging as a result of the emergence of antibiotic-resistant bacteria. Aminoglycosides, as broad-spectrum antibiotics, are increasingly being used clinically; however, for most effective employment of aminoglycosides, a comprehensive understanding of aminoglycoside resistance genes’ prevalence and dissemination is required. Therefore, to better understand the global resistance status of aminoglycoside antibiotics and the prevalence of antibiotic-resistance genes (ARGs) in various bacterial species, this systematic review gathered relevant data from multiple studies. Two primary resistance mechanisms—aminoglycoside enzymatic modification and 16S rRNA methylation—were assessed, and the prevalence of the corresponding ARGs was described. The coexistence of aminoglycoside ARGs with other ARGs was also demonstrated, as was the relationship between aminoglycoside ARGs and resistant phenotypes. The lack of effective therapeutic agents to combat resistant pathogens presents a real threat to public health. The combination of aminoglycosides with other antibiotics may provide a novel treatment strategy.

简介:AbstractObjective:To elucidate the epidermal melanocyte distribution according to sex, age, and body part with the goal of providing benchmark data for the diagnosis and therapeutic effect evaluation of pigmentary skin diseases.Methods:Epidermal melanocytes and keratinocytes were assessed using direct immunofluorescence staining, and the melanocyte density and epidermal thickness were calculated. The obtained data were statistically analyzed using SPSS Version 20.0 software. An independent-samples t test was used to compare the data between two groups, while data among three or more groups were compared by one-way analysis of variance. Data correlations were evaluated using Pearson correlation analysis.Results:Melanocytes were uniformly distributed among the keratinocytes in the basal layer, and the average ratio of melanocytes to keratinocytes was 1:7. Among them, the ratio in males was 1:6.5 and that in females was 1:7.4, with no significant difference (P= 0.127). The melanocyte density gradually declined as age increased; the ratio was 1:5.8 before 50 years of age without an obvious downtrend. The average melanocyte density was 1:7.9 within 51 to 65 years of age and 1:8.5 at >65 years of age, and the difference was statistically significant (P < 0.01). Obvious differences were found in the melanocyte density among different body parts; in descending order, these densities were as follows: face (1:4.0) >neck (1:5.1) >hip (1:5.7) >upper limb (1:7.4) >lower limb (1:8.3) >lower back (1:9.2) >thorax and abdomen (1:9.9). The melanocyte density was not related to the epidermal thickness.Conclusion:The melanocyte density showed a declining trend with age and significantly changed after 50 years of age. The melanocyte density was associated with body part; specifically, the density in the face, neck, and hip was higher than that in the limbs and torso. However, the melanocyte density was not associated with sex or epidermal thickness.
