ABSTRACT

Objective:To correlate neutrophil/lymphocyte ratio and platelet/lymphocyte ratio with diabetic nephropathy (DN).Methods:A total of 160 patients with type 2 diabetes mellitus (T2DM) who received treatment between January 2017 and October 2020 in People's Hospital of Suzhou National New & Hi-Tech Industrial Development Zone were included in this study. These patients were randomly divided into DN [urinary albumin-to-creatinine ratio (UACR) ≥ 30 μg/mg, n = 85) and non-DN (UACR < 30 μg/mg, n = 75)] groups according to UACR values. A total of 150 healthy controls who concurrently received health examination were included in the control group. The clinical data and biochemical indicators were collected in each group and their clinical characteristics were compared. The factors that affect DN were analyzed using a logistic regression model. Results:Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) in patients with T2DM were (2.14 ± 1.12) and (175.00 ± 56.21), respectively, which were significantly higher than those in the healthy controls [(1.53 ± 0.29), (142.70 ± 37.25), t = 3.584, 5.642, both P < 0.05). NLR and PLR in the DN group were (2.64 ± 1.22) and (278.00 ± 72.23), respectively, which were significantly higher than those in the non-DN group [(1.80 ± 0.90), (193.00 ± 62.40), t = 2.738, 3.166, both P < 0.05)]. Logistic regression analysis showed that NLR and PLR are the risk factors of DN ( OR = 5.981, 1.807; 95% CI = 2.104-15.563, 1.327-2.795). Conclusion:Combined detection of NLR and PLR in the clinic may help early prediction of DN.

ABSTRACT

Objective To investigate the molecular mechanism of the inhibitory effects of rhizoma coptidis on multi-drug resistant uropathogenic Escherichia coli.Methods High-throughput RNA sequencing ( RNA-seq ) was performed to investigate the transcriptome in a multi-drug resistant uropathogenic Escherichia coli strain (NB8) treated with water decoction of rhizoma coptidis .Agar dilution test was used to determine the minimal inhibitory concentration ( MIC) of water decoction of rhizoma coptidis against the NB 8 strain.A growth curve was drawn to evaluate the effects of water decoction of rhizoma coptidis on the growth of NB8 strain.Total RNAs were extracted from the NB 8 strain after treated with the water decoction of rhizo-ma coptidis for 30 minutes and then synthetized to cDNA by reverse transcription after screening out the rRNAs.The HiSeq 2000 sequencing system was used for transcriptome sequencing .The TopHat software was used to map and analyze the RNA-Seq reads, and then Cufflinks was run to assemble transcripts and es-timate their abundances .The differential expression , GO enrichment and KEGG metabolic pathway were fur-ther analyzed .The NB8 strain dealt with normal saline was used as negative control .Results The MIC of water decoction of rhizoma coptidis to NB 8 strain was 12.5 mg/ml.There were 3665 genes expressed in NB8 strain treated with water decoction of rhizoma coptidis and 3430 genes expressed in NB8 strain treated with normal saline .The number of differentially expressed genes was 1428 including 921 up-regulated genes and 507 down-regulated genes .Those differentially expressed genes mainly enriched in the modules of binding and catalysis.The genes concerning cell adhesion , apoptosis and multicellular process were up-regulated, while those concerning the regulation of enzyme activities were down-regulated.Results of the KEGG meta-bolic pathway enrichment analysis showed that the genes concerning synthetic pathway of LPS were signifi -cantly up-regulated as well as those encoding the repair polymerase Ⅲthat was involved in DNA replication . However , the genes concerning fatty acid metabolism , histidine metabolism , thiamine metabolism , folate metabolism and iron carrier in ribosome synthesis showed overall down-regulation.Conclusion The tran-scriptome in uropathogenic Escherichia coli strain treated with rhizoma coptidis was profiled .The main mo-lecular mechanism of the inhibitory effects of rhizoma coptidis on uropathogenic Escherichia coli was to de-stroy the cell wall of Escherichia coli, affect the replication of DNA and regulate the transcription and transla-tion of proteins .This study illustrated that the inhibitory effects of rhizoma coptidis on uropathogenic Esche-richia coli were achieved in multiple levels .

ABSTRACT

Objective To investigate the distribution of 22 beta-lactamase genes and enzyme activities in multi-drug resistant Acinetobacter baumannii (MDRAB). Methods Sixty-two MDRAB strains were isolated from the First Affiliated Hospital, College of Medicine, Zhejiang University. Twenty-two beta-lactamase genes were analyzed by PCR and verified by DNA sequencing. Enzyme activities of extended spectrum beta-lactamases (ESBLs) , cephalosporinase ( AmpC) and metallo-beta-lactamases ( MBL) were detected by the modified three-dimensional method using enzyme extraction. Results In 62 MDRABs, 51 (82.3% ) , 50 (80.6% ) and 36 (58.1% ) isolates were found to carry blaTEM, blaOXA-23 cluster, and blaADC, respectively. The rest 19 genes were not detected in this study. DNA sequencing and genomic comparison showed that 5 isolates carrying blaTEM had the same genotype as blaTEM-l , 6 isolates carrying blaOXA-23 cluster had the same genotype as blaOXA-23 carbapenemases (accession; CAB69042. 1) , and 2 isolates carrying blaADC had the same genotype as blaADC-like (accession: EU081908). Thirty-two isolates (51.6% ) produced ESBLs and AmpC, 19 isolates (30.6% ) produced ESBLs only, and 1 isolate (1.6%) produced AmpC only; and no isolate produced MBL. Conclusion MDRAB carrying blaOXA-23 carbapenemase and blaADC AmpC in this study are of high drug resistance.

ABSTRACT

AIM:To study the differentiation of rat marrow-derived mesenchymal stem cells(MSCs) into myoid cells in vitro . METHODS:The MSCs of SD rat were cultured?passaged?induced and differentiated in vitro used by routine culture technique, and evaluated by FACScan flow cytometer,detected by immunohistochemistry and analyzed by Hitachi H-600 transmission electron microscope(TEM). RESULTS:FACScan shows that cells expressed the antigens of CD29 and CD44, not those of CD11b and CD45; cells show positive response of staining with desmin and myoglobin after processing by two compounds of 5-azacytidine and amphotericin B. There were stripform zone of myofilament without any organells beside the edge of membrane in myoid cell of induction and differentiation checked by TEM. CONCLUSION: The passaged cells were MSCs and the MSCs may have specific gene structures that can differentiate into myoid cells. The demethylation or hypomethylation may conduct by compounds of 5-azacytidine and amphotericin B, which could be involved in activating phenotype-specific genes to differentiate MSCs into myoid cells. There are good outlook on clinical treatment of illness of myatrophy using by MSCs.
