Newcastle disease (ND), caused by the Newcastle disease virus (NDV), poses a severe threat to global poultry farming, leading to significant losses annually. The limitations of current ND vaccines in terms of efficacy and duration of protection have encouraged the exploration of novel vaccine designs. This study aimed to adopt a delayed-lysis Salmonella strain χ11218 as vaccine delivery vector.

Introduction: Cholesterol homeostasis has been identified as an essential downstream pathway of mutations in TP53. Esophageal cancer is one of the most prevalent malignancies exhibiting the mutation.

Objectives: To explore the significance of cholesterol metabolism-related characteristics in tumor phenotype and treatment outcomes of esophageal cancer.

The H9N2 avian influenza virus is a still a great threat to poultry production and public health due to its variation. The highly conserved extracellular domain, M2 ion channel (M2e), and the nuclear protein (NP) are usually considered to be potential targets for a broad-spectrum influenza vaccine. In this study, we took use of a regulated delayed lysis Salmonella χYL56 lacking the sifA gene as a delivery vector to deliver a lumazine synthase (LS) based nanoparticle vaccine decorating with three copies of M2e (H9N2, H5N1 and H1N1 subtype, 3M2e) and NP protein, without or with LTB adjuvant, yielding S311 and S325, respectively.

Introduction: Necrotic enteritis (NE), caused by , has seen a surge in chicken populations recently due to the ban on antibiotic growth promoters in feed.

Methods: In this research, screening and identification of probiotics with strong antagonistic ability against from 34 wild bird fecal isolates, followed by analysis of probiotic characteristics and carbon source metabolic activity. Strains exhibiting favorable antagonistic activity against were subsequently employed in vivo study to evaluate their protective efficacy against challenge in locally-sourced broilers.

Background: Two cycles of neoadjuvant PD-1 blockade plus chemotherapy induced favorable pathological response and tolerant toxicity in patients with locally advanced esophageal squamous cell carcinoma (ESCC). However, approximately 25% of patients relapsed within 1 year after surgery, indicating that a short course of treatment may not be sufficient. Therefore, exploring the effects of intensive treatment is needed for optimal clinical outcomes.

Introduction: Traditional DBS is usually conducted under local anesthesia (LA) which is intolerable to some patients, DBS under general anesthesia (GA) was opted to extended surgical indication. This study aimed to compare the efficacy and safety of bilateral subthalamic deep brain stimulation (STN-DBS) for Parkinson's disease (PD) under asleep and awake anesthesia state in 1-year postoperative follow-up.

Methods: Twenty-one PD patients were assigned to asleep group and 25 patients to awake group.

Background: Immune checkpoint inhibitor (ICI) monotherapy and neoadjuvant immunochemotherapy have shown promising results in esophageal carcinoma. However, it is still unclear whether more courses of immunochemotherapy are therapeutically better. We aimed to investigate the safety and efficacy of three courses of neoadjuvant treatment for patients with locally advanced esophageal squamous cell carcinoma (ESCC).

Background: The neutrophil-to-lymphocyte ratio (NLR) has been shown to have prognostic value in several common cancers. This study aimed to investigate the prognostic value of NLR in patients with advanced oesophageal squamous cell carcinoma (ESCC) after definitive chemoradiotherapy (dCRT).

Methods: A retrospective analysis was performed on 158 patients with advanced ESCC who received dCRT from January 2012 to December 2018.

Background: Immunotherapy is effective in treating unresectable esophageal squamous cell carcinoma (ESCC), but little is known about its role in the preoperative setting. The aim of this study was to evaluate the safety, feasibility and efficacy of neoadjuvant treatment with camrelizumab plus chemotherapy in locally advanced ESCC.

Methods: Patients diagnosed with locally advanced ESCC were retrospectively included if they had received neoadjuvant camrelizumab plus nab-paclitaxel and S1 capsule followed by radical esophagectomy between November, 2019 and June, 2020 at Sun Yat-sen University Cancer Center.

Aims: This follow-up study aimed to examine the 8-year efficacy and safety of subthalamic nucleus (STN) deep brain stimulation (DBS) for patients with Parkinson's disease (PD) in southern China.

Methods: The follow-up data of 10 patients with PD undergoing STN-DBS were analyzed. Motor symptoms were assessed before and 1, 3, 5, and 8 years after the surgery with stimulation-on in both off-medication (off-med) and on-medication (on-med) status using the Unified Parkinson's disease Rating Scale Part III.

Aims: Our aim was to search for clinical predictors of good glycemic control in patients starting or intensifying oral hypoglycemic pharmacological therapy.

Methods: A multicenter, prospective cohort of 499 diabetic subjects was enrolled in this study: patients with newly diagnosed diabetes (NDM group) or poor glycemic control with oral antidiabetic drugs (OADs) (PDM group). All subjects then started or intensified OADs therapy and followed up for 91 days.

Deep brain stimulation of the subthalamic nucleus is recognized as the most effective treatment for moderate and advanced Parkinson's disease. Programming of the stimulation parameters is important for maintaining the efficacy of deep brain stimulation. Voltage is considered to be the most effective programming parameter.

Introduction: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well-established surgical treatment for Parkinson's disease (PD). However, there is currently no consensus on the best timing for this surgery. The aim of our study is to compare the therapeutic efficacy of bilateral STN DBS in patients with PD with early and late motor complications.

Article Synopsis
  • This study looked at whether a blood test called glycated albumin (GA) is better for checking blood sugar levels than another test called hemoglobin A1c (HbA1c) for people starting treatment for type 2 diabetes.
  • The researchers included new diabetes patients at hospitals in Beijing and checked their blood tests at different times after starting treatment.
  • They found that both GA and HbA1c levels went down after treatment, and GA showed early changes that could help doctors decide if the treatment was working.
