It is generally believed that Carbapenem-resistant Enterobacterales (CRE) colonization is primarily responsible for systemic infection in humans. However, there is no consensus on whether decolonization should be recommended in clinical practice. In China, the specific situation of CRE colonization and consequent systemic infection in hospitalized patients necessitates further exploration.

is a major healthcare-associated pathogen inducing infectious diarrhea. Approximately 25-33% of patients with antibiotic-associated diarrhea (AAD) and 90% of patients with pseudomembranous enteritis are caused by infection (CDI). Stool samples were collected from hospitalized adults with presumptive AAD in four nonneonatal intensive care units (ICUs).

The gut microbiota composition of intensive care unit (ICU) patients suffering from -positive diarrhea (CDpD) is poorly understood. This prospective study aims to use 16S rDNA (and metagenome) sequencing to compare the microbiota composition of 58 (and 5) ICU patients with CDpD (CDpD group), 33 (and 4) ICU patients with -negative diarrhea (CDnD group), and 21 (and 5) healthy control subjects (control group), as well as CDpD patients in the AB ( = 34; A/B: ), AB ( = 7), and AB ( = 17) subgroups. For 16S rDNA data, OTU clustering (tool: UPARSE), taxonomic assignment (tool: RDP classifier), α-diversity, and β-diversity analyses (tool: QIIME) were conducted.

Introduction: The fecal metabolome of Clostridium difficile (CD) infection is far from being understood, particularly its non-volatile organic compounds. The drawbacks of current tests used to diagnose CD infection hinder their application.
Objective: The aims of this study were to find new characteristic fecal metabolites of CD infection and develop a metabolomics model for the diagnosis of CD infection.
Carbapenem-resistant K. pneumoniae (CR-KP) posts significant public health challenge worldwide. The aim of this study is to assess clinical characteristics and molecular epidemiology of CR-KP infections with Multilocus sequence typing (MLST) and Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF) in Central China.

In China, however, hospital staff do not routinely test for CDI, leading to under-diagnosis and poor patient outcomes. Locally generated CDI data can help assess the magnitude of the problem and strengthen approaches for CDI prevention and control.

A small number of strains express the binary toxin (CDT), which is generally found in 027 (ST1) and/or 078 (ST11) in clinic. However, we isolated a binary toxin-positive non-027, non-078 LC693 that is associated with severe diarrhea in China.

Antibiotic treatment of HAP may lead to subsequent Clostridium difficile infection (CDI). Baseline data on the occurrence of CDI among HAP patients in China are currently unavailable.

Therefore, we investigate the risk factors for healthcare-associated CREC infection and study the incidence, antibiotic resistance and medical costs of CREC infections in our hospital.
Methods: We conducted a retrospective, matched case-control-control, parallel study in a tertiary teaching hospital.
Ethnopharmacological Relevance: Gan-kang granules (GKG) contains the extracts from eight Chinese herbs and is a traditional Chinese composite prescription for treatment of hepatitis B. Icariin, emodin and psoralen are main effective ingredients of the medicine.
Aim Of The Study: In this research, pharmacokinetic comparisons of icariin, emodin and psoralen from the extracts of herba Epimedii, Nepal dock root and Ficus hirta yahl, and GKG were conducted.
A HPLC-MS fingerprint method has been developed based on the consistent chromatographic features of the major chemical constituents among 10 batches of Hedyotis diffusa Willd. Chromatographic separation was conducted on a Hypersil-Keystone Hypurity C(18) column using methanol:water:acetic acid as the mobile phase. Major compounds, including oleanolic acid, ursolic acid and ferulic acid, were analysed by HPLC-MS.

Tumor cell migration and metastasis are critically regulated by chemokines and their receptors. CC Chemokine Receptor 7 (CCR7) plays a critical role in mediating chemotactic and invasive responses in cancers. However, whether or not CCR7 is a desired target of cancer therapy needs further investigation in terms of its biodegradation and availability in vivo.

Radix Astragali extract (RAE) is obtained from Astragalus membranaceus. It consists of Astragalus polysaccharide and Astragalus membranaceus saponins. In the study, we observed the subchronic toxicity of RAE in Sprague-Dawley rats and beagle dogs to evaluate the safety dosage range in clinical application.
