This review aims to summarize and evaluate the latest clinical evidence and mechanistic studies regarding acupuncture for the treatment of allergic rhinitis AR. Compared with traditional medical treatment, acupuncture treatment of allergic rhinitis has fewer side effects and drug dependence, especially for those patients who do not respond well to medical treatment, acupuncture treatment has become a new hope. By analyzing results from RCTs, systematic reviews, and meta-analyses, the significant effectiveness of acupuncture in improving AR symptoms is clarified.

Sodium taurocholate co-transporting polypeptide (NTCP) has been identified as an entry receptor for hepatitis B virus (HBV), but the molecular events of the viral post-endocytosis steps remain obscure. In this study, we discovered that manganese (Mn) could strongly inhibit HBV infection in NTCP-reconstituted HepG2 cells without affecting viral replication. We therefore profiled the antiviral effects of Mn2+ in an attempt to elucidate the regulatory mechanisms involved in early HBV infection.

Central post-stroke pain (CPSP) is a chronic neuropathic pain syndrome that commonly occurs after cerebral stroke, and it severely impairs the daily activities of stroke patients. A number of fundamental and clinical studies support the theory that CPSP is mainly caused by ischemic and hemorrhagic injury of the spinal-thalamic-cortical neural pathway. However, the underlying reasons of CPSP genesis and development are far from clear.

Ebola and Marburg (EBOV and MARV) filoviral infections lead to fatal hemorrhagic fevers and have caused over 30 outbreaks in the last 50 years. Currently, there are no FDA-approved small molecule therapeutics for effectively treating filoviral diseases. To address this unmet medical need, we have conducted a systematic structural optimization of an early lead compound, -(4-(4-methylpiperidin-1-yl)-3-(trifluoromethyl)phenyl)-4-(morpholinomethyl)benzamide (), borne from our previously reported hit-to-lead effort.

Background: Liposarcoma (LPS) is a kind of malignancy of soft tissue usually found in the retroperitoneal, limb, or neck region, and some may be detected with delayed symptoms (pain or palpable mass), and less frequently occurs in organs of the digestive system. In contrast, Dedifferentiated liposarcoma (DDLPS) is a common histological subtype of LPS. The present study reported a case of dedifferentiated liposarcoma originating in the gallbladder.

Background: Colorectal cancer (CRC) is a leading cause of morbidity and mortality, and timely diagnosis and intervention are crucial for cancer patients. Transfer RNA-derived fragments (tRFs) play a noncoding regulatory role in organisms. Serum EV(extracellular vesicles), as an integral mediator of intercellular transmission of genetic information vesicles in Transfer RNA-derived fragment (tRF RNA), are expected to be minimally invasive diagnostic and predictive biologic factors of CRC.

Background: Genome-wide association studies have identified dozens of genomic loci for obesity. However, functional genes and their detailed genetic mechanisms underlying these loci are mainly unknown. In this study, we conducted an integrative study to prioritize plausibly functional genes by combining information from genome-, transcriptome- and proteome-wide association analyses.

Individuals diagnosed with autism spectrum disorders often face persistent challenges in social interaction and engage in repetitive and stereotyped behaviors. Parenting a child with autism can profoundly affect parents both physically and psychologically, potentially leading to negative impacts on their mental health. This study employs a network meta-analysis methodology to evaluate the comparative effectiveness of mental health interventions specifically designed for parents of autistic children.

Background: Despite significant reductions in mother-to-child HIV-1 transmission risks due to the advancements and scale-up of antiretroviral therapy (ART), the global burden of HIV-1 drug resistance (HIVDR) in treatment-naive and treatment-experienced children and adolescents remains poorly understood. In this study, we conducted a systematic review and meta-analysis to estimate the prevalence of HIVDR in these populations globally, regionally, and at the country level.

Methods: We systematically searched PubMed, Embase, and Web of Science for studies reporting HIVDR in treatment-naive and treatment-experienced children and adolescents from inception to June 28, 2024.

  • - The study examines flea parasitism in rodents in the Alxa Desert of Inner Mongolia, highlighting how fleas serve as vectors for zoonotic diseases and emphasizing the importance of understanding their host selection.
  • - Researchers captured rodents from April to October 2022, analyzing flea abundance across different species, sexes, and reproductive statuses, revealing that flea species and abundance varied significantly, with preferences for specific rodent hosts.
  • - Findings showed that fleas preferred male hosts and non-reproductive rodents, with peak parasitism occurring in spring and autumn, while factors like host species, sex, reproductive status, and season influenced flea abundance, with host species being the most significant.

  • CDI (Clostridioides difficile infection) is a significant post-operative complication with a poor prognosis and no standardized treatment, often caused by various factors affecting the gut environment.
  • A patient with a long history of bowel obstruction underwent surgery for colon issues but developed CDI shortly after, leading to a successful initial treatment, but unfortunately, the patient did not continue medication and later died.
  • The case emphasizes the importance of addressing potential CDI risks in patients with chronic bowel conditions and the necessity of consistent medication to prevent recurrence after treatment.

  • - Brandt's voles, a common rodent in Inner Mongolia, hoard food in underground warehouses during autumn in preparation for winter, but it's unclear if they show a division of labor in this behavior.
  • - An experiment with three different treatments (varied food supply and competition) revealed that voles displayed two hoarding behaviors: high food hoarding and low food hoarding, with feeding behavior dominating their actions across all treatments.
  • - Despite the differences in hoarding amounts, there were no significant distinctions in body weight, sex, or inquiry abilities between high and low hoarders; however, high hoarders exhibited better spatial memory.
