We investigated changes in the composition of cervical fluid at different phases of the female rat reproductive cycle. Fluid was collected from the cervix of rats by direct cervical flushing and analyzed for changes in Na and Cl content and osmolarity. Following sacrifice, the cervix was harvested and expressions of mRNA and protein for ENaCs, CFTR and AQPs were measured using qPCR and immunohistochemistry, respectively. Cervical fluid Na and Cl content was high during estrus, but osmolarity was high during metestrus and diestrus. Expressions of CFTR, AQP-1 and AQP-2 in the cervix were high during estrus, but low during diestrus. Expression of ENaC (α, β, γ), AQP-5 and AQP-7 was high during metestrus and diestrus and low during estrus. Changes in expression of ion channels in the cervix could explain changes in cervical fluid composition during the estrus cycle phases that could affect female fertility.

Immunosuppression is one key feature of mesenchymal stromal cells (MSCs) that has high expectations for therapeutic use. The influence of pro-inflammatory stimuli can modify the characteristics of MSCs and enhance immunosuppressive properties. The local postoperative environment contains cytokines, MSCs, and immune cells in high quantities, and their mutual influence is still unclear.

Electronic address:

Ethnopharmacological Relevance: Jiawei Ermiao Granules (JWEMGs), a traditional Chinese herbal formulation, has been widely used in China for the treatment of human papillomavirus (HPV) infections. However, the underlying mechanisms through which it exerts its antiviral effects remain poorly understood.

Aim Of The Study: This study aimed to investigate the potential mechanisms by which JWEMGs modulate vaginal microecology and clear HPV infections, utilizing clinical trials, metagenomic sequencing, and in vitro models.

Background: Pulmonary tuberculosis (PTB) accounts for 85% of all reported tuberculosis cases globally. Extrapulmonary involvement can occur in isolation or along with a pulmonary focus as in the case of patients with disseminated tuberculosis (TB). EPTB can occur through hematogenous, lymphatic, or localized bacillary dissemination from a primary source, such as PTB and affects the brain, eye, mouth, tongue, lymph nodes of neck, spine, bones, muscles, skin, pleura, pericardium, gastrointestinal, peritoneum and the genitourinary system as primary and/or disseminated disease.

Department of TCM Internal Medicine, Ganzhou Nankang Hospital of Traditional Chinese Medicine, Ganzhou, China.

CSF1R-related disorder, a catastrophic neurodegenerative disease, arises from genetic mutations in the colony-stimulating CSF1R. Initial misdiagnosis is common, as demonstrated by this case involving a 52-year-old female who presented with symptoms of limb numbness and weakness. Differential diagnosis first indicated Parkinsonism, lacunar infarction, and cervical spondylosis.
