Haemaphysalis concinna, a three-host tick vector of several pathogens, poses a high risk to the health of humans and livestock. However, knowledge of the seasonal activities, relative density and other ecological characteristics of this tick is quite limited and fragmentary. This knowledge gap represents a bottleneck in our understanding of the health risks associated with tick-borne pathogens.

Francisella-like endosymbionts (FLEs) with significant homology to Francisella tularensis (γ-proteobacteria) have been characterized in several tick species, whereas knowledge on their distribution and population dynamics in ticks remains meager. Hence, in the current study, we identified a novel Francisella-like endosymbiont (FLEs-Hd) from the tick Haemaphysalis doenitzi and evaluated the putative functions of this symbiont. Results indicated that FLEs-Hd had 100% infection rate and a perfect vertical transmission in H. doenitzi, and that it is distributed in ovaries, malpighian tubules, salivary glands and midguts of the ticks, suggesting that FLEs-Hd presumably is a crucial symbiont of the host without specific tissue tropism. To further explore the function of the symbiont, the population dynamics of FLEs-Hd at each developmental stage of ticks and in tissues at different reproductive statuses were determined by real-time quantitative polymerase chain reaction (real-time qPCR). Results showed that the high density and regular population dynamics of FLEs-Hd appeared in female ovaries, suggesting that the symbiont may provide necessary nutrients or regulators to ensure normal ovary development of ticks.

Emerging research has shown that polyunsaturated fatty acids (PUFAs) benefit human health and exert anti-cancer effects. However, there is little understanding of the specific mechanisms by which PUFAs regulate the cells of the ovarian granulosa tumor. In the current study, we investigate the effects and the possible mechanisms of PUFAs on human ovarian tumor cells development. KGN cells were treated with omega-3. Small interfering (siRNA) and specific activator were used to knock down and overexpress gene expression in KGN cells. The protein content levels were analyzed by Western blot. Cell viability, proliferation and apoptosis assay were performed to examine the cellular development. And the level of glucose uptake in KGN cells were assessed by 2-DG measurement. The results showed that omega-3 treatment reduced cell viability, proliferation and increased cell apoptosis. Further studies showed that omega-3 also reduced GLUT1/4 protein content and cellular glucose uptake. Subsequent knockdown and overexpression of OCT4 using  siRNA and O4I2 (OCT4 activator) showed that OCT4 was involved in the regulations of omega-3 on GLUT1/4 expression and cell development. Our data demonstrate that omega-3 inhibits cellular development by down-regulating GLUT1/4 expression and glucose uptake in KGN cells, which are mediated through OCT4.

Infrared thermography technology is a diagnostic imaging modality that converts temperature information on the surface of the human body into visualised thermograms. This technology has the capacity to intuitively detect the presence of certain abnormal conditions or foci in the human body. In recent years, the application of this technology in medicine has become increasingly extensive, especially in the areas of auxiliary diagnosis and early screening of diseases.

Cisplatin chemotherapy has been used as the main treatment for different types of cancer. However, cisplatin chemotherapy-induced peripheral neuropathic pain (CIPNP) seriously affects the treatment process and quality of life of patients. In addition, it impacts the underlying mechanism and prevention and treatment strategies, indicating that drug selection and efficacy evaluation need to be further investigated. Furthermore, an animal model that is more consistent with the pathological mechanism needs to be developed. In this study, we describe and discuss the methods of developing and detecting CIPNP models in rats and mice induced by cisplatin chemotherapy. The aim was to improve the modeling rate and develop animal models that are more consistent with the developmental pattern of the disease. In addition, the study provides ideal reference animal models for clinical research and drug discovery and development.

The incidence and mortality rates of digestive tract tumors, especially gastric and colorectal cancers, are high worldwide. Owing to their unique advantages, such as efficient drug loading, safety, and targeting properties, nanoparticles (NPs) have demonstrated great potential in the treatment of gastrointestinal tumors. However, their practical application is limited by several factors, such as high costs, few clinical trials, and long approval periods. In this review, we summarize three types of immunotherapeutic nanomaterial drugs for gastrointestinal tumors: organic, inorganic, and hybrid nanomaterials. This article also discusses the current status of research and development in this field and the advantages of each type of material to provide theoretical references for developing new drugs and advancing clinical research.

Oxaliplatin, a third-generation platinum-based chemotherapeutic agent, has shown substantial efficacy in cancer treatment. However, its associated side effects, particularly chemotherapy-induced peripheral neuropathic pain (CIPNP), continue to challenge cancer survivors globally. Clinically, it frequently presents as numbness, coldness, and discomfort in the limbs and extremities. Duloxetine is advised for analgesic purposes. Despite its clinical relevance, both the application methods and the underlying mechanisms of oxaliplatin-induced CINP warrant further investigation. Consequently, more precise animal models are needed to explore the mechanisms and progression of this condition. This review consolidates recent advancements in rat and mouse models of oxaliplatin-induced CINP, with the aim of enhancing modeling success rates and developing models that more accurately mirror disease progression. Such models are essential for advancing clinical research and drug development.

The complexity of the tumor immune microenvironment (TIME), which is composed of mainly tumor cells, immune cells, and cytokines, is a major obstacle limiting the effectiveness of immunotherapy, and the interactions among these factors in the TIME determine the efficacy of antitumor immunity. Over the past few years, nanomaterials, owing to their unique physicochemical properties, multifunctionality, and good targeting ability, have gradually become important tools for modulating the immune microenvironment. By precisely delivering immunomodulatory factors, nanomaterials can effectively activate dendritic cells (DCs), enhance the function of effector T cells, and reverse the immunosuppressive state of tumor-associated macrophages (TAMs). In addition, nanomaterials can alleviate the local hypoxic and acidic tumor microenvironment, which in turn promotes immune cell function and enhances the antitumor immune effect. In light of the aforementioned associations, we summarize the existing studies, systematically describe the latest research progress on the use of nanomaterials in regulating the tumor immune microenvironment, and analyze the potential applications and challenges in tumor immunotherapy, with the goal of providing new therapeutic directions and strategies for tumor immunotherapy.

The intestinal microbiota, present in vast numbers within the human body, plays a pivotal role, with its composition and abundance varying significantly across individuals. This gut microbiota not only contributes to normal physiological development but also impacts the initiation, progression, resolution, and prognosis of various diseases. Recent studies have increasingly illuminated the connection between intestinal microbiota and pain, with a particular focus on the relationship between gut microbiota and neuropathic pain (NP). NP, an acute and chronic pain disorder arising from sensory nervous system injury, encompasses both peripheral and central neuropathic pain. Evidence suggests that intestinal microbiota influences NP occurrence and may modulate its severity. This review synthesizes current research findings on the microbiota-NP relationship, aiming to establish a theoretical foundation for future clinical investigations.

Peripheral Nerve Injury (PNI) is a common condition in modern clinical practice, characterized by a high incidence and significant debilitating consequences. This narrative review systematically delineates the dual functions of key pro-inflammatory (e.g., IL-1β, IL-6, IL-17) and anti-inflammatory (e.g., IL-4, IL-10, IL-13) interleukins in the spatiotemporal context of nerve injury. This is a narrative review, the review systematically summarizes the dual pro-inflammatory and anti-inflammatory roles of interleukins in peripheral nerve injury. The therapeutic potential of interleukin-based treatment strategies, including inhibitors, agonists, and their combined applications with cell therapy, gene therapy, physical therapy, etc., was explored, and the limitations of current research and future research directions were pointed out. By synthesizing current evidence, this review aims to provide a comprehensive mechanistic overview and highlight emerging interleukin-centric therapeutic paradigms for PNI.
