Background: By comparing the three lateral approaches to thyroidectomy, the feasibility and clinical effects were analyzed, and the advantages of the lateral approach were summarized.

Methods: From January 2022 to January 2023, 52 patients with thyroid cancer admitted to our department were selected and subjected to Lateral approach for thyroidectomy. Among them, 31 patients underwent thyroidectomy via the supraclavicular approach, 13 patients underwent endoscopic thyroidectomy via the subclavicular approach, and 8 patients underwent endoscopic thyroidectomy via the axillary approach.

Background: Haemaphysalis longicornis is an obligate hematophagous ectoparasite, which transmits various pathogens to humans, livestock and wild animals. Hexokinase (HK) is a key regulatory enzyme of the glycolytic pathway in the organisms. However, little is known about hexokinase and its functions in ticks.

Carbon source serves as a crucial factor for microalgal lipid biosynthesis. The supplied exogenous inorganic or organic carbon affects lipid accumulation in microalgae under stress conditions. However, the impacts of different carbon availability on glycerolipid metabolism, triacylglycerol (TAG) metabolism in particular, still remain elusive in microalgae.

Partial nitrification coupled with anammox (PN/A) process is an energy-efficient approach for nitrogen removal from low C/N wastewater. In this study, PN/A was achieved with optimal oxygen supply from a green microalga, . The PN process was first initiated within 35 days, and the following algae-intensified PN then reached the steady state within the next 32 days.

This study aimed to explore the main effects of environmental risk factors as well as their interaction effects with miRNA on the risk of autism spectrum disorder (ASD). One hundred fifty-nine ASD children (ASD group) and 159 healthy children (control group), aged 2-6 years, were included in this study. ASD diagnoses were based on DSM-5 criteria.

Background: Mild cognitive impairment (MCI), as a common neurodegenerative aging disease representing an intermediate stage between normal cognitive functioning and dementia, poses an excessive burden on health care. The clinical benefit of Chinese herbal medicines (CHMs) for MCI remains inconclusive. This study is aimed at evaluating the efficacy and acceptability of CHMs through meta-analysis and trial sequential analysis (TSA).

Antimicrobial peptides (AMPs) are small molecules produced by a myriad of cells and play important roles not only in protecting against infections and sustaining skin barrier homeostasis but also in contributing to immune dysregulation under pathological conditions. Recently, increasing evidence has indicated that AMPs, including cathelicidin (LL-37), human β-defensins, S100 proteins, lipocalin 2, and RNase 7, are highly expressed in psoriatic skin lesions. These peptides broadly regulate immunity by interacting with various immune cells and linking innate and adaptive immune responses during the progression of psoriasis.

Great interest has been taken in the use of beneficial bacteria for allergic diseases recently, but the underlying mechanisms through which probiotics induces immune regulation or immune tolerance are poorly understood. We aimed to explore whether Lactobacillus rhamnosus GG (LGG)-induced beneficial effect relates to the change of microbiota. LGG was administered orally to mouse model of ovalbumin (OVA)-induced allergic airway inflammation.

High linear energy transfer radiation is known to deposit higher energy in tissues and cause greater toxicity compared to low-LET irradiation. Local immunosuppression is frequently observed after irradiation (IR). Dendritic cells (DCs) play important roles in the initiation and maintenance of the immune response.

Cilostazol(CTL) is a phosphodiesterase inhibitor, which has been widely used as anti-platelet agent. It also has preventive effects on various central nervous system (CNS) diseases, including ischemic stroke, Parkinson's disease and Alzheimer disease. However, the molecular mechanism underlying the protective effects of CTL is still unclear, and whether CTL can prevent I/R induced cognitive deficit has not been reported.

The spectra measurements mode that suitable for haploid maize kernel identification was explored using MicroNIR-1700 series of miniature near infrared spectrometer by JDSU company. Based on Near Infrared Spectroscopy (NIRS) qualitative analysis techniques, we conducted a comparative study using reflectance and transmittance spectra to identify haploid maize kernels. Partial least squares-discriminant analysis (PLS-OLDA) was used to compress the pretreated spectral data, and then the identification models were built based on Support Vector Machine (SVM).

A rapid and sensitive liquid chromatography-tandem mass spectrometric method was developed for the first time and validated for the determination of cefprozil diastereomers in human plasma. The plasma samples were prepared by protein precipitation using acetonitrile. Detection was performed using an electronic spray ion source in the negative ion mode, operating in the multiple reaction monitoring of the transitions m/z 388.

1-Hydroxyl-2,3,5-trimethoxyxanthone (HM-1) is one of the main constituents extracted from Halenia elliptica D. Don, which is a traditionally used Tibetan medicinal plant. The aim of this study was to illustrate the proposed metabolic pathways of HM-1 and identify which cytochrome P450 (CYP450) isoforms involved in its metabolism by using pooled human liver microsomes (HLMs) and recombinant CYP450 isoforms with selective chemical inhibitors.

Article Synopsis
  • - Berberine (BBR) is known for various health benefits, such as lowering cholesterol, managing diabetes, protecting the heart, and reducing inflammation, but its low plasma levels in patients challenge explanations for these effects.
  • - A study using advanced liquid chromatography techniques examined how BBR and its metabolites are distributed in various tissues of rats after oral administration, revealing that BBR is concentrated in organs like the liver, kidneys, and brain.
  • - The findings suggest that the higher concentrations of BBR and its metabolites in tissues compared to blood could explain its positive effects on human health, as these compounds remain stable in vital organs.

Berberine (BBR) has been confirmed to show extensive bioactivities for the treatments of diabetes and hypercholesterolemia in clinic. However, there are few pharmacokinetic studies to elucidate the excretions of BBR and its metabolites. Our research studied the excretions of BBR and its metabolites in rats after oral administration (200 mg/kg).

The aim of this study is to investigate the effect of echinacoside (ECH) on cholinergic neurotransmitter extracellular of hippocampus and striatum and its possible mechanisms of neuro-protective effect against vascular dementia rats. In this study brain microdialysis technique combined with HPLC-IMER-ECD (high-performance liquid chromatography-immobilized enzyme reactor-electrochemical detector) was used. The bilateral common carotid arteries occluded in two times operation at 72 h interval for vascular dementia model rats were used and the successful vascular dementia model rats were examined by Morris water maze.

Halenia elliptica D. Don is a Tibetan herb and medicinal preparations containing Halenia elliptica have been commonly used for the treatment of hepatitis B virus infection in China. The metabolism of 1-hydroxy-2,3,5-trimethoxy-xanthone (HM-1) to its metabolites is mediated through cytochrome P450 enzymes.

The metabolisms of five xanthones isolated from a Tibetan medicinal herb Halenia elliptica D. Don, including 1-hydroxy-2,3,5-trimethoxy-xanthone (HM-1), 1-hydroxy-2,3,4,7-tetramethoxy-xanthone (HM-2), 1-hydroxy-2,3,4,5-tetramethoxy-xanthone (HM-3), 1,7-dihydroxy-2,3,4,5-tetramethoxy-xanthone (HM-4) and 1,5-dihydroxy-2,3-dimethoxy-xanthone (HM-5), were studied in rat liver microsomes in vitro. High performance liquid chromatography coupled to ion trap time-of-flight mass spectrometry (LC-ESI-IT-TOF) was applied for identification of metabolites of five xanthones mentioned above and (1)H NMR was used to elucidate the major metabolites.
