The present study aims to investigate the effect and the molecular mechanism of N-(2-hydroxyphenyl)-2-phenazinamine (NHP) isolated from Nocardiopsis exhalans against the proliferation of human lung cancer cells. The cytotoxic activity of NHP against A549 and H520 cells was determined using MTT assay. The cytotoxic activity of NHP against A549 and H520 lung cancer cells showed excellent activity at 75 μg/mL and damage the mitochondrial membrane and nucleus by generating oxidative stress. NHP causes nuclear condensation and induces apoptosis which was confirmed using AO/EB and PI/DAPI dual staining assay. Moreover, the NHP downregulates the oncogenic genes such as IL-8, TNFα, MMPs and BcL2 and also upregulates the expression of apoptosis marker genes such as Cyto C, p53, p21, caspase 9/3 in A549 and H520 human lung cancer cells. Considering the strong anticancer activity of NHP against lung cancer, NHP may be further evaluated as a potential anticancer drug for the treatment of lung cancer.

The widespread application of genome editing to treat and cure disease requires the delivery of genome editors into the nucleus of target cells. Enveloped delivery vehicles (EDVs) are engineered virally derived particles capable of packaging and delivering CRISPR-Cas9 ribonucleoproteins (RNPs). However, the presence of lentiviral genome encapsulation and replication proteins in EDVs has obscured the underlying delivery mechanism and precluded particle optimization.

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.
Study on mechanism of Spatholobi Caulis in the treatment of the hand-foot skin reaction induced by targeted drug therapy based on network pharmacology and molecular docking: An observational study.

Department of Traditional Chinese Medicine, Shanghai Fourth People's Hospital Affiliated to Tongji University of Medicine, Shanghai, China.
Based on network pharmacology and molecular docking methods, this study explored its active compounds and confirmed its potential mechanism of action against Hand-foot skin reaction induced by tumor-targeted drugs. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and UniProt Database were used to obtain the active ingredients and target proteins of Spatholobi Caulis. All hand-foot skin reaction (HFSR)-related targets were obtained with the help of the Human Gene Database, Online Mendelian Inheritance in Humans (OMIM), DisGeNET and DrugBank databases.

Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.
