SGMS1 facilitates osteogenic differentiation of MSCs and strengthens osteogenesis-angiogenesis coupling by modulating Cer/PP2A/Akt pathway.

Mesenchymal stem cell (MSC)-mediated coupling of osteogenesis and angiogenesis is a critical phenomenon in bone formation. Herein, we investigated the role and mechanism of SGMS1 in the osteogenic differentiation of MSCs and, in combination with osteogenesis and angiogenesis, to discover new therapeutic targets for skeletal dysplasia and bone defects. SGMS1 addition accelerated MSC osteogenic differentiation, whereas SGMS1 silencing suppressed this process.

Baicalein improves the symptoms of polycystic ovary syndrome by mitigating oxidative stress and ferroptosis in the ovary and gravid placenta.

Background: Polycystic ovary syndrome is a metabolic and hormonal disorder that is closely linked to oxidative stress. Within individuals diagnosed with PCOS, changes occur in the ovaries, resulting in an excessive buildup of iron and peroxidation of lipids, both of which may be associated with the occurrence of ferroptosis. Baicalein, a flavonoid found in the roots of Scutellaria baicalensis and widely known as Chinese skullcap, is known for its anti-inflammatory and anti-ferroptotic properties, which protect against various diseases.

NTRK1 knockdown induces mouse cognitive impairment and hippocampal neuronal damage through mitophagy suppression via inactivating the AMPK/ULK1/FUNDC1 pathway.

Hippocampal neuronal damage may induce cognitive impairment. Neurotrophic tyrosine kinase receptor 1 (NTRK1) reportedly regulates neuronal damage, although the underlying mechanism remains unclear. The present study aimed to investigate the role of NTRK1 in mouse hippocampal neuronal damage and the specific mechanism.

Assessment of a novel variation in DHODH gene causing Miller syndrome: The first report in Chinese population.

Background: Miller syndrome is a rare type of postaxial acrofacial dysostosis caused by biallelic mutations in the DHODH gene, which is characterized mainly by craniofacial malformations of micrognathia, orofacial clefts, cup-shaped ears, and malar hypoplasia, combined with postaxial limb deformities like the absence of fifth digits.

Methods: In this study, a prenatal case with multiple orofacial-limb abnormities was enrolled, and a thorough clinical and imaging examination was performed. Subsequently, genetic detection with karyotyping, chromosomal microarray analysis (CMA) and whole-exome sequencing (WES) was carried out.

Prednisone plus IVIg compared with prednisone or IVIg for immune thrombocytopenia in pregnancy: a national retrospective cohort study.

Background: The responses of intravenous immunoglobulin (IVIg) or corticosteroids as the initial treatment on pregnancy with ITP were unsatisfactory. This study aimed to assess the safety and effectiveness of prednisone plus IVIg prednisone or IVIg in pregnant patients with immune thrombocytopenia (ITP).

Methods: Between 1 January 2010 and 31 December 2020, 970 pregnancies diagnosed with ITP at 19 collaborative centers in China were reviewed in this observational study.

STING modulates necrotic cell death in CD4 T cells via activation of PARP-1/PAR following acute systemic inflammation.

Regulated cell death profoundly affects on the progress of inflammatory and immune responses in various acute inflammatory diseases, as seen in sepsis and trauma. However, the mechanisms underlying CD4 T cells death have not yet been fully addressed. We demonstrated that interferon genes (STING) promoted excessive Poly (ADP-ribose) polymerase 1 (PARP-1) activity stimulated by endotoxin, which in turn induced apoptosis-inducing factor (AIF)-independent but PARP-1 dependent programmed cell death.

Immune regulation in polycystic ovary syndrome.

A polycystic ovarian syndrome (PCOS) is the most common endocrine disorder affecting females. Furthermore, it is a heterogeneous disease with a variety of etiologies and outcomes. Patients frequently complain about infertility, irregular menstruation, acne, seborrheic dermatitis, hirsutism, and obesity.

Update Advances on C-Reactive Protein in COVID-19 and Other Viral Infections.

Severe coronavirus disease 2019 (COVID-19) can manifest as a viral-induced hyperinflammation with multiorgan dysfunction. It has been documented that severe COVID-19 is associated with higher levels of inflammatory mediators than a mild disease, and tracking these markers may allow early identification or even prediction of disease progression. It is well known that C-reactive protein (CRP) is the acute-phase protein and the active regulator of host innate immunity, which is highly predictive of the need for mechanical ventilation and may guide escalation of treatment of COVID-19-related uncontrolled inflammation.

Congenital bilateral cryptorchidism in an infant conceived after maternal breast cancer treatment: A case report.

Background: The incidence of breast cancer among women of reproductive age is increasing, as well as the desire for children at late childbearing age. Identifying factors that may be associated with fetal malformation and maternal and fetal prognosis has gained importance. We describe a 32-year-old woman with breast cancer who gave birth to a son with congenital bilateral cryptorchidism after treatment, with a literature review performed.

Prediction of postpartum hemorrhage in pregnant women with immune thrombocytopenia: Development and validation of the MONITOR model in a nationwide multicenter study.

Globally, postpartum hemorrhage (PPH) is the leading cause of maternal death. Women with immune thrombocytopenia (ITP) are at increased risk of developing PPH. Early identification of PPH helps to prevent adverse outcomes, but is underused because clinicians do not have a tool to predict PPH for women with ITP.

Killing cervical cancer cells by specific chimeric antigen receptor-modified T cells.

The aim is to investigate the in vivo and in vitro killing effect of mesothelin chimeric antigen receptor T cells (MESO-CAR-T) in cervical squamous cell carcinoma. MESO-CAR-T cells were successfully constructed. In vitro verification of the killing effect of MESO-CAR-T cells was evaluated in the presence of SiHa cells by the lactate dehydrogenase release assay and cytokine release assay.

Use of mesothelin as a tumor-associated antigen in cervical squamous cell carcinoma.

Aim: To explore the feasibility of using mesothelin (MESO) as a tumor-associated antigen (TAA) in cervical squamous cell carcinoma and its function in the development of cervical cancer.

Methods: We collected eight cervical tissue samples of squamous cell carcinoma as the test group and eight samples of cervicitis as the control group from patients who underwent a hysterectomy because of a diagnosis of myoma. Then we used western blotting to screen for a potential TAA in cervical squamous cell carcinoma samples.

A clinical analysis of small-cell neuroendocrine carcinoma of the gynecologic tract: report of 20 cases.

Objective: The aim of this retrospective observational study was to analyze the clinical and pathological characteristics of small-cell neuroendocrine carcinoma of the gynecologic tract (SCNCGT).

Methods: Twenty patients with SCNCGT were enrolled and their clinic-pathological features were analyzed. All patients were treated at the Beijing Obstetrics and Gynecology Hospital, Capital Medical University, China, and were followed up until December 31, 2017.

Effect of Dandelion Extracts on the Proliferation of Ovarian Granulosa Cells and Expression of Hormone Receptors.

Background: In the current society, infertility related to age has become a social problem. The in vitro fertilization (IVF) success rate in women with poor ovarian response (POR) is very low. Dandelion extract T-1 (DE-T1) is an effective component of the extract from the leaves and stems of Taraxacum officinale, which is one of the medicines used in some patients with POR, but its molecular mechanism remains unclear.

Hydrogen-rich Water Exerting a Protective Effect on Ovarian Reserve Function in a Mouse Model of Immune Premature Ovarian Failure Induced by Zona Pellucida 3.

Background: Premature ovarian failure (POF) is a disease that affects female fertility but has few effective treatments. Ovarian reserve function plays an important role in female fertility. Recent studies have reported that hydrogen can protect male fertility.

Fibronectin expression is critical for liver fibrogenesis in vivo and in vitro.

Increased fibronectin (FN) expression has an important role during liver fibrosis. The present study examined FN expression in rats subjected to carbon tetrachloride (CCl4)‑induced liver fibrosis. In addition, the potential mechanisms underlying fibrogenesis were investigated by exposing hepatic stellate cells (HSCs) to transforming growth factor‑β (TGF‑β), which is a known inducer of myofibroblastic transformation of HSCs.
