Acanthopanax senticosus cultures fermented by Lactobacillus rhamnosus enhanced immune response through improvement of antioxidant activity and inflammation in crucian carp (Carassius auratus).

Lactic acid bacteria (LAB) have been recognized as safe microorganism that improve micro-flora disturbances and enhance immune response. A well-know traditional herbal medicine, Acanthopanax senticosus (As) was extensively utilized in aquaculture to improve growth performance and disease resistance. Particularly, the septicemia, skin wound and gastroenteritis caused by Aeromonas hydrophila threaten the health of aquatic animals and human.

Yeast cell membrane-camouflaged PLGA nanoparticle platform for enhanced cancer therapy.

Temozolomide (TMZ) is an oral DNA-alkylating drug used in colorectal cancer (CRC) chemotherapy. In this work, we proposed a safe and biomimetic platform for macrophages-targeted delivery of TMZ and O-benzylguanine (O-BG). TMZ was loaded in poly (D, l-lactide-coglycolide) (PLGA) nanoparticles, followed by sequential coating with O-BG-grafted chitosan (BG-CS) layers and yeast shell walls (YSW) via layer-by-layer assembly (LBL) process, forming TMZ@P-BG/YSW biohybrids.

Transcriptomic insights into the immune response of the intestine to Aeromonas veronii infection in northern snakehead (Channa argus).

Intestinal inflammation is a protective response that is implicated in bacterial enteritis triggered by gastrointestinal infection. The immune mechanisms elicited in teleost against the infection of Aeromonas veronii are largely unknown. In this study, we performed a de novo northern snakehead (Channa argus) transcriptome assembly using Illumina sequencing platform.

Dietary supplementation of probiotics fermented Chinese herbal medicine Sanguisorba officinalis cultures enhanced immune response and disease resistance of crucian carp (Carassius auratus) against Aeromonas hydrophila.

Aeromonas hydrophila, a Gram-negative bacterium, is one of the major pathogens causing bacterial sepsis in aquatic animals due to drug resistance and pathogenicity, which could cause high mortality and serious economic losses to the aquaculture. Sanguisorba officinalis (called DiYu in Chinese, DY) is well known as herbal medicine, which could inhibit the growth of pathogenic bacteria, hemostasis and regulate the immune response. Moreover, the active ingredients in DY could remarkably reduce drug resistance.

Self-Deliverable Peptide-Mediated and Reactive-Oxygen-Species-Amplified Therapeutic Nanoplatform for Highly Effective Bacterial Inhibition.

An "antibiotic-free strategy" provides a viable option to address bacterial infections, especially for the "superbug" challenge. However, the undesirable antibacterial activity of antibiotic-free agents hinders their practical applications. In this study, we developed a combination antibacterial strategy of coupling peptide-drug therapy with chemodynamic therapy (CDT) to achieve the effective bacterial inhibition.

Analysis of hospitalization costs and length of stay for oral cancer patients undergoing surgery: Evidence from Hunan, China.

Objective: To provide information about hospitalization costs and length of stay (LOS) for inpatients undergoing oral cancer (OC) surgery, and to investigate the association of hospitalization costs and LOS with demographics, tumor subsite, surgery-related and hospital characteristics.

Methods: Data extracted from Chinese National Health Statistics Network Reporting System database in Hunan, China during 2017-2019 were analyzed using quantile regression models.

Results: A total of 6,420 OC patients undergoing surgery were identified.

Super-pH-Sensitive Mesoporous Silica Nanoparticle-Based Drug Delivery System for Effective Combination Cancer Therapy.

A multifunctional nanoplatform based on mesoporous silica nanoparticles (MSNs) was developed for combinational tumor therapy. Doxorubicin (DOX) was chosen as an antitumor drug and loaded into mesopores of MSNs via physical absorption. Then, a tumor-targeted fusion peptide conjugated with 2,3-dimethylmaleic anhydride (DTCPP) and a therapeutic peptide conjugated with 2,3-dimethylmaleic anhydride (DTPP) were introduced to the surface of MSNs as super-pH-sensitive nanovalves through disulfide linkages.

Novel oligopeptide nanoprobe for targeted cancer cell imaging.

Here we designed and constructed a tryptophan-phenylalanine-phenylalanine-tryptophan (WFFW) tetrapeptide, which generated photostable and tunable fluorescence emission signals from 340 nm to 500 nm. The WFFW tetrapeptide could self-assemble into a spherical nanostructure with enhanced fluorescence intensity. Driven by π-π stacking and hydrogen bond interaction, WFFW co-assembled with arginine-glycine-aspartic acid (RGD) modified WFFW to form a cancer-targeted fluorescent nanoprobe, which could selectively image the cancer cells.

Efficacy and safety of endoscopic submucosal tunnel dissection for superficial esophageal squamous cell carcinoma and precancerous lesions.

Aim: To evaluate the clinical outcomes of patients who underwent endoscopic submucosal tunnel dissection (ESTD) for esophageal squamous cell carcinoma (ESCC) and precancerous lesions.

Methods: ESTD was performed in 289 patients. The clinical outcomes of the patients and pathological features of the lesions were retrospectively reviewed.

Morphology control of self-deliverable nanodrug with enhanced anticancer efficiency.

The morphology of nanomedicines has a large influence on the anticancer efficiency of therapeutic agents in biological systems. In this study, camptothecin (CPT)-based nanodrugs with helical and spherical shapes were simply built without the need of any additional carriers. Self-deliverable spherical nanodrug represented a therapeutic advantage over the helical one, which was uncovered from the in vitro toxicity assay.

Clinicopathological and prognostic significance of cyclin D1 amplification in patients with breast cancer: a meta-analysis.

Purpose: Cyclin D1 plays a critical role in tumorigenesis and the regulation of the G1/S transition in the cell cycle. The relationship between cyclin D1 amplification and clinicopathological parameters in patients with breast cancer remains controversial and its impact on survival outcome is not completely clear. We conducted a meta-analysis to investigate the associations between cyclin D1 gene amplification and certain clinicopathological characteristics and the prognosis in breast cancer.

Simultaneous determination of bioactive constituents in Danggui Buxue Tang for quality control by HPLC coupled with a diode array detector, an evaporative light scattering detector and mass spectrometry.

Danggui Buxue Tang (DBT), a classical traditional Chinese formula comprising Radix Angelicae Sinensis (RAS) and Radix Astragali (RA), has been widely used to treat menopausal irregularity in Chinese women for nearly 800 years. In this study, a comprehensive analytical method of simultaneously determining the main types of bioactive constituents, eighteen in all from the formula, involving flavonoids, saponins, organic acid and some volatile compounds, was developed. This method was based on HPLC coupled to a diode array and evaporative light scattering detectors (HPLC-DAD-ELSD) on a common reverse-phase C(18) column.
