ALK-Positive Adenocarcinoma After Acquired Resistance to Lorlatinib and Transformation to SCLC: A Case Report.

SCLC transformation is a phenomenon that is rarely described in ALK-rearranged cancers after treatment with ALK tyrosine kinase inhibitors, and it is exceedingly rare after lorlatinib use. We report the first case of a patient with an ALK-EML4 rearrangement who was resistant to lorlatinib simply due to transformation to SCLC and rapidly achieved partial response after traditional etoposide combined with cisplatin therapy. In addition, we provide a fishplot that visualizes tumor evolution on the basis of next-generation sequencing, which may predict small cell transformation and facilitate early treatment.

3,4-Dimethoxychalcone, a caloric restriction mimetic, enhances TFEB-mediated autophagy and alleviates pyroptosis and necroptosis after spinal cord injury.

Caloric restriction mimetics (CRMs) mimic the favourable effects of caloric restriction (CR) and have been shown to have therapeutic effects in neuroinflammatory disease. However, whether CRMs improve the functional recovery from spinal cord injury (SCI) and the underlying mechanism of action remain unclear. In this study, we used the CRMs 3,4-dimethoxychalcone (3,4-DC) to evaluate the therapeutic value of CRMs for SCI.

Yap signalling regulates ductular reactions in mice with CRISPR/Cas9-induced glycogen storage disease type Ia.

Glycogen storage disease type Ia (GSD-Ia) is caused by a deficiency in the glucose-6-phosphatase (G6Pase, G6pc) enzyme, which catalyses the final step of gluconeogenesis and glycogenolysis. Accumulation of G6pc can lead to an increase in glycogen and development of fatty liver. Ductular reactions refer to the proliferation of cholangiocytes and hepatic progenitors, which worsen fatty liver progress.

Role of necroptosis in traumatic brain and spinal cord injuries.

Background: Traumatic brain injury (TBI) and spinal cord injury (SCI) are capable of causing severe sensory, motor and autonomic nervous system dysfunctions. However, effective treatments for TBI and SCI are still unavailable, mainly because the death of nerve cells is uncontrollable. Necroptosis is a type of programmed cell death and a critical mechanism in the process of neuronal cell death.

Purpose: To evaluate the effect of patient participation in arthroscopic partial meniscectomy (APM) on rehabilitation and patient satisfaction.

Methods: A total of 86 patients of traumatic longitudinal vertical meniscus tears, between January 2017 and December 2020 at the First Affiliated Hospital of Zhejiang Chinese Medical University, met the inclusion and exclusion criteria. The patients in the intraoperative participation group (n = 33) were awake and could watch the screen during APM and communicate with the surgeon in the surgery; patients who underwent APM in the traditional mode were classified as the traditional group(n = 53).

Functions and mechanisms of cytosolic phospholipase A in central nervous system trauma.

Central nervous system (CNS) trauma, including traumatic brain injury and spinal cord injury, has a high rate of disability and mortality, and effective treatment is currently lacking. Previous studies have revealed that neural inflammation plays a vital role in CNS trauma. As the initial enzyme in neuroinflammation, cytosolic phospholipase A (cPLA2) can hydrolyze membranous phosphatides at the sn-2 position in a preferential way to release lysophospholipids and ω3-polyunsaturated fatty acid dominated by arachidonic acid, thereby inducing secondary injuries.

Formononetin Improves the Survival of Random Skin Flaps Through PI3K/Akt-Mediated Nrf2 Antioxidant Defense System.

Cadmium induces placental glucocorticoid barrier damage by suppressing the cAMP/PKA/Sp1 pathway and the protective role of taurine.

Cadmium (Cd) exposure during pregnancy damages the placental glucocorticoid (GC) barrier, exposes the foetus to excess corticosterone (CORT) levels, and eventually inhibits foetal development. In addition, taurine (Tau) alleviates the toxicity of Cd on liver and kidney, but limited data are available on the role of Tau against the toxicity of heavy metals on female reproduction and fetal development. The present study was conducted to investigate the specific mechanism of Cd-induced placental GC barrier damage and the protective role of Tau.

Role of NETosis in Central Nervous System Injury.

Central nervous system (CNS) injury is divided into brain injury and spinal cord injury and remains the most common cause of morbidity and mortality worldwide. Previous reviews have defined numerous inflammatory cells involved in this process. In the human body, neutrophils comprise the largest numbers of myeloid leukocytes.

Inhibition of PLA2G4E/cPLA2 promotes survival of random skin flaps by alleviating Lysosomal membrane permeabilization-Induced necroptosis.

Necrosis that appears at the ischemic distal end of random-pattern skin flaps increases the pain and economic burden of patients. Necroptosis is thought to contribute to flap necrosis. Lysosomal membrane permeabilization (LMP) plays an indispensable role in the regulation of necroptosis.

Here, we have synthesized cyclic helix B peptide (CHBP) and investigated its role in flap survival and the underlying mechanisms.

Abnormal deviation in the measurement of residual urine volume using a portable ultrasound bladder scanner: a case report.

In addition to being suitable for the assessment of residual urine volume, the use of a portable bladder scanner can also assist medical staff in developing a reasonable urination plan. Portable scanners can help medical personnel to estimate the height and/or relaxation of the bladder neck for pelvic floor muscle training, assist in the efficacy evaluation of muscarinic antagonists in patients with neurogenic detrusor overactivity, and even determine whether the urine in the bladder of pediatric patients meets the criteria for catheterization to obtain urine samples. However, in the case described herein, we encountered abnormal deviation between the data measured by a portal bladder scanner and actual catheterization.
