ABSTRACT

Objective:To analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province.Methods:This is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors.Results:Among 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes ( P<0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 ( P<0.05). Compared with those with visual acuity <0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity ≥0.1 was significantly decreased ( P<0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate ( P<0.05). Conclusions:The DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.

ABSTRACT

Objective:To investigate the bacterial composition and antimicrobial resistance profile of clinical isolates from bloodstream infections in China.Methods:The clinical bacterial strains isolated from blood culture were collected during January 2020 to December 2020 in member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS). Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute(CLSI, USA). WHONET 5.6 was used to analyze data.Results:During the study period, 10 043 bacterial strains were collected from 54 hospitals, of which 2 664 (26.5%) were Gram-positive bacteria and 7 379 (73.5%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (38.6%), Klebsiella pneumoniae (18.4%), Staphylococcus aureus (9.9%), coagulase-negative Staphylococci (7.5%), Pseudomonas aeruginosa (3.9%), Enterococcus faecium (3.3%), Enterobacter cloacae (2.8%), Enterococcus faecalis (2.6%), Acinetobacter baumannii (2.4%) and Klebsiella spp (1.8%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 27.6% and 74.4%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci were detected. More than 95% of Staphylococcus aureus were sensitive to rifampicin and SMZco. No vancomycin-resistant Enterococci strains were detected. Extended spectrum β-lactamase (ESBL) producing Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 48.4%, 23.6% and 36.1%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.3% and 16.1%, respectively; 9.6% of carbapenem-resistant Klebsiella pneumoniae strains were resistant to ceftazidime/avibactam combination. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii. The prevalence rate of carbapenem-resistance of Pseudomonas aeruginosa was 23.2%. Conclusions:The surveillance results in 2020 showed that the main pathogens of bloodstream infection in China were gram-negative bacteria, while Escherichia coli was the most common pathogen, and ESBL-producing strains declined while carbapenem-resistant Klebsiella pneumoniae kept on high level. The proportion and the prevalence of carbapenem-resistant Pseudomonas aeruginosa were on the rise slowly. On the other side, the MRSA incidence got lower in China, while the overall prevalence of vancomycin-resistant Enterococci was low.

ABSTRACT

Aim To analyze differential expression and interaction of β-catenin/ICAT proteins in HL60 cells when they were induced into monocytic differentiation, and to figure out the mechanism of NSC67657 in cellu-lar induction. Methods HL60 cells were treated by 10 μmol · L-1 NSC67657 , and cellular differentiation could be observed by cytochemical staining and flow cytometry. Then, RT-PCR and Western blot were em-ployed to determine the differential expression of β-catenin/ICAT genes and proteins. Co-immunoprecipi-tation assay was used to confirm the interaction of β-catenin/ICAT proteins, and laser co-focus light mi-croscopy technology was used to co-indentify proteins differential expression and intracellular location. Re-sults HL60 cells could be induced into monocytic dif-ferentiation after 5 days treatment using 10μM NSC67657 . The CD14 ( +)% cells could be up to o-ver 90%, and cytochemical staining reports were con-sistent with this result. The expressions of ICAT gene and protein were up-regulated significantly ( P <0. 01 ) , but the expressions ofβ-catenin gene and pro-tein, on the contrary, were down-regulated(P<0. 05) when HL60 cells were induced into monocytic differen-tiation. From co-immunoprecipitation assay findings, ICAT protein interacted with β-catenin protein, and the absorbance of protein electrophoresis bands in-creased in differentiated cells. From laser co-focus light microscopy assay findings, the fluorescence of ICAT and β-catenin protein could be both observed in cytoplasm and nucleus. In drug treated HL60 cells, the fluorescence of ICAT protein was enhanced both in cytoplasm and nucleus, however, the fluorescence ofβ-catenin protein, which looked like transferring into different organelles, decreased significantly in nucleus, but increased in cytoplasm. Conclusions HL60 cells could be induced into monocytic differentiation by NSC67657 and β-catenin/ICAT proteins differentially expressed during cellular differentiation. The enhanced interaction of β-catenin/ICAT proteins and β-catenin protein transferring from nucleus into cytoplasm indi-cates that NSC67657 probably induces HL60 cells into monocytic differentiation through down-regulating β-catenin protein and blockingβ-catenin protein from nu-cleus.
