Knee osteoarthritis: A review of animal models and intervention of traditional Chinese medicine.

Background: Knee osteoarthritis (KOA) characterized by degeneration of knee cartilage and subsequent bone hyperplasia is a prevalent joint condition primarily affecting aging adults. The pathophysiology of KOA remains poorly understood, as it involves complex mechanisms that result in the same outcome. Consequently, researchers are interested in studying KOA and require appropriate animal models for basic research.

The retrieval time was set as from the establishment of the database till August 30, 2021.

Low dose cadmium inhibits syndecan-4 expression in glycocalyx of glomerular endothelial cells.

Cadmium (Cd) is one of the most polluting heavy metal in the environment. Cd exposure has been elucidated to cause dysfunction of the glomerular filtration barrier (GFB). However, the underlying mechanism remains unclear.

Evaluation of the effectiveness of using flipped classroom in puncture skills teaching.

Background: The effectiveness of flipped classroom (FC) on puncture skills in medical education is still uncertain. This study aimed to assess the role of the FC model in puncture skills and investigate the acceptance and approval of FC among medical students and instructors.

Methods: A mixed research approach of quasi-experimental research design and descriptive qualitative research was conducted in September 2022 for one month, using an FC teaching method that combined instructional videos and group learning.

UBE2L3 Promotes Oxidative Stress-regulated Necroptosis to Accelerate Osteosarcoma Progression.

Background: Osteosarcoma is a highly invasive bone marrow stromal tumor with limited treatment options. Oxidative stress plays a crucial role in the development and progression of tumors, but the underlying regulatory mechanisms are not fully understood. Recent studies have revealed the significant involvement of UBE2L3 in oxidative stress, but its specific role in osteosarcoma remains poorly investigated.

A Multifunctional Bimetallic Nanoplatform for Synergic Local Hyperthermia and Chemotherapy Targeting HER2-Positive Breast Cancer.

Anti-HER2 (human epidermal growth factor receptor 2) therapies significantly increase the overall survival of patients with HER2-positive breast cancer. Unfortunately, a large fraction of patients may develop primary or acquired resistance. Further, a multidrug combination used to prevent this in the clinic places a significant burden on patients.

Microbial and metabolic profiles unveil mutualistic microbe-microbe interaction in obesity-related colorectal cancer.

Obesity is a risk factor for colorectal cancer (CRC), and the involvement of gut microbiota in the pathogenesis of obesity and CRC is widely recognized. However, the landscape of fecal microbiome and metabolome distinguishing patients with obesity-related CRC from obesity remains unknown. Here, we utilize metagenomic sequencing and metabolomics from 522 patients with CRC and healthy controls to identify the characteristics of obese CRC.

An integration-free iPSC line SDQLCHi065-A from a patient with down syndrome, possessing a 47, XY,+21, inv(9)(p12q21),16qh + karyotype.

Down syndrome, a chromosomal aneuploidy genetic disorder, is primarily caused by trisomy 21 in all cells of a patient's body. In fewer cases, it can be attributed to a trisomy 21 chimera or trisomy 21 in specific cells within the body. We established an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) of an 8-day-old boy with Down syndrome possessing a 47, XY,+21, inv(9)(p12q21),16qh + karyotype.

KIF18A inactivates hepatic stellate cells and alleviates liver fibrosis through the TTC3/Akt/mTOR pathway.

Activation of hepatic stellate cells (HSCs) has been demonstrated to play a pivotal role in the process of liver fibrogenesis. In this study, we observed a decrease in the expression of KIF18A in fibrotic liver tissues compared to healthy liver tissues, which exhibited a negative correlation with the activation of HSCs. To elucidate the molecular mechanisms underlying the involvement of KIF18A, we performed in vitro proliferation experiments and established a CCl4-induced liver fibrosis model.

Exogenous PRAS40 reduces KLF4 expression and alleviates hypertrophic scar fibrosis and collagen deposition through inhibiting mTORC1.

Background: To identify the anti-fibrosis effect of PRAS40 in scar, and its potential mechanism.

Methods: We constructed a rat model of hypertrophic scarthat was locally injected the PRAS40 overexpression adenoviruses, mTORC1 inhibitor MHY1485 and activator rapamycin, and further observed the pathological changes of skin tissue and the severity of fibrosis by HE, Masson and sirius red staining, and analyzed the deposition of a-SMA and collagen I by western blot and immunofluorescence test. Meanwhile, the co-localization of KLF4 with a-SMA and type I collagen was analyzed, as well as the regulatory effect of PRAS40 on KLF4.

Endothelium-specific deletion of p62 causes organ fibrosis and cardiac dysfunction.

Background: The autophagy adapter SQSTM1/p62 is crucial for maintaining homeostasis in various organs and cells due to its protein-protein interaction domains and involvement in diverse physiological and pathological processes. Vascular endothelium cells play a unique role in vascular biology and contribute to vascular health.

Methods: Using the Cre-loxP system, we generated mice with endothelium cell-specific knockout of p62 mediated by Tek (Tek receptor tyrosine kinase)-cre to investigate the essential role of p62 in the endothelium.

Postoperative recurrence of diffuse sclerosing thyroid cancer in an adolescent patient: A case report.

Background: Papillary thyroid cancer is an inert malignant tumor with a good response to surgical treatment, low recurrence and metastasis rate, and good prognosis. Diffuse sclerosing thyroid cancer is an invasive subtype that is more common in young people, with a higher rate of lymph node metastasis and recurrence, and a relatively poor prognosis.

Patient Concerns: A 13-year-old girl underwent radical surgery for diffuse sclerosing thyroid cancer.

Chaihu Shugan prevents cholesterol gallstone formation by ameliorating the microbiota dysbiosis and metabolic disturbance in mice.

Cholesterol gallstone (CGS) is a biliary tract disorder requiring treatment in approximately 20% of patients. The efficacy of Chaihu Shugan in preventing CGS recurrence after successful treatment remains uncertain. We examined the preventive efficacy of Chaihu Shugan using a CGS mouse model and used multi-omics to study the interplay between gut microbiota, metabolism, and gene expression.

Causal relationships between delirium and Parkinson's disease: a bidirectional two-sample Mendelian randomization study.

Background: Previous observational studies have suggested a notably elevated prevalence of delirium in individuals diagnosed with Parkinson's disease (PD), thereby implying a potential increased susceptibility to delirium among PD patients. However, it is imperative to acknowledge that observational studies inherently possess limitations, rendering it arduous to establish a definitive causal or reverse causal association between delirium and PD.

Methods: To explore the relationship between delirium and PD, a bidirectional two-sample Mendelian randomization (MR) was conducted using summary statistics obtained from genome-wide association studies.

Identification of an 8 HPV-related RNA signature as a novel prognostic biomarker for squamous cell carcinoma of the head and neck.

Squamous cell carcinoma of the head and neck (SCCHN) is a commonly detected cancer worldwide. Human papillomavirus (HPV) is emerging as an important risk factor affecting SCCHN prognosis. Therefore, identification of HPV status is essential for effective therapies in SCCHN.

[Psychological problems in breast cancer patients should be taken seriously].

With the transformation of the biopsychosocial medical model, psychological problems and related interventions for breast cancer patients have received more and more attention. Patients often have various psychological problems, in diagnosis, treatment, and even in the state of disease-free survival, such as anxiety and depression, which not only seriously reduces the quality of life, but also affects the follow-up treatment and increases the risk of recurrence and metastasis. Therefore, physicians should perform routine psychological screening and appropriate intervention for patients.
