Aims The aim of this study was to assess the prevalence and drug resistance Ureaplasma species Mycoplasma hominis in outpatients with genital manifestation from 2005 2013 Hangzhou, China. Methods A total 2689 female 2336 male patients various symptoms were included study. Species identification antimicrobial susceptibility test performed by using mycoplasma IST-2 kit. Results rate 39.9%, M 1.2% patients, coinfection 13.4%; while males, 18.8%, 0.4%, 2.9%. Moreover, significantly high positive...

Endoscopy is currently recognized as the gold standard for assessing inflammatory bowel disease (IBD) severity. However, because procedure costly and invasive, endoscopy not suitable frequently monitoring intestinal inflammation. In this study, our aim was to identify noninvasive, low cost, convenient biomarkers identifying endoscopic IBD activity.In total, 246 patients with (131 Ulcerative colitis (UC) 115 Crohn's (CD)) 369 healthy controls were recruited retrospective study. activity...

This study aimed to investigate the role of quinolone resistance-determining regions (QRDRs) DNA gyrase (encoded by gyrA and gyrB) topoisomerase IV parC parE) associated with fluoroquinolone resistance. A total 114 Ureaplasma spp. strains, isolated from clinical female patients symptomatic infection, were tested for species distribution susceptibility four fluoroquinolones. Moreover, we analysed QRDRs compared these 14 ATCC reference strains serovars identify mutations that caused...

The multilocus sequence typing (MLST) scheme of Ureaplasma based on four housekeeping genes (ftsH, rpL22, valS, and thrS) was described in our previous study; here we introduced an expanded MLST (eMLST) with improved discriminatory power, which developed by adding two putative virulence (ureG mba-np1) to the original scheme. To evaluate power eMLST, a total 14 reference strains serovars 269 clinical (134 isolated from symptomatic patients 135 obtained asymptomatic persons) were investigated....

Abstract Background In December 2019, an outbreak of a novel coronavirus pneumonia, now called COVID-19, occurred in Wuhan, Hubei Province, China. which is caused by the severe acute respiratory syndrome 2 (SARS-CoV-2), has spread quickly across China and rest world. This study aims to evaluate initial chest thin-section CT findings COVID-19 patients after their admission at our hospital. Methods Retrospective tertiary referral hospital Anhui, From January 22, 2020 February 16, 2020, 110...

Background The colonization of Ureaplasma species in genital tract is related with male infertility. However, it has been postulated based upon limited study that virulence to serotype specificity. aim this was determine the distribution serovars infertile males and analyze their role Methods A total 358 urethral swabs samples were obtained from males. culture performed using a commercially available Mycoplasma IST 2 kit. Serovars determined by real‐time polymerase chain reaction (real‐time...

Platelet transfusion refractoriness (PTR) remains a difficult problem in patients requiring long-term platelet supportive care. However, there are little data on the frequency of antibodies multiply transfused Chinese patients. Moreover, relationship between peripheral regulatory T cells (Tregs) and PTR unclear.We retrospectively studied alloimmunization against antigens receiving multiple transfusions 2013 2017. Monoclonal antibody solid-phase test (MASPAT) kits were used to screen for...

A majority of known eubacterial genomes are characteristic GC skew, i.e., the leading strand has exceeding number G over C. The cause this compositional bias is still not very clear. In study, we chose five pairs from distantly related bacterial genera, Buchnera, Haemophilus, Mycoplasma, Mycobacterium, and Synechococcus, each containing one with strong skew other weak skew. Through comparison orthologous genes in these found that neither chromosomal rearrangement nor CDS direct relationship

ABO blood group system is the most important in transfusion and transplantation medicine. Diffuse large B-cell lymphoma (DLBCL) common type of non-Hodgkin lymphomas (NHLs) worldwide. There have been some studies that could affect thus strategy. However, mechanisms affecting not fully elucidated so far. Here, we report a case patient who was 72-year-old Chinese man came to our hospital for medical advice because cervical lymphadenophathy. The subsequently diagnosed with diffuse by lymph-node...
