In our previous research, we proved that ailanthone (AIL) inhibits the growth of gastric cancer (GC) cells and causes apoptosis by inhibiting P23. However, we still find some GC organoids are insensitive to AIL. We have done some sequencing analysis and found that the insensitive strains are highly expressed in PARP1.

This research aimed to assess the effectiveness of combining induction chemotherapy (IC) or adjuvant chemotherapy (AC) with concurrent chemoradiotherapy (CCRT) in patients with T3-4N0-1M0 nasopharyngeal carcinoma (NPC). Before propensity score matching(PSM),we retrospectively collected 457 patients with T3-4N0-1M0 NPC treated with CCRT with or without IC/AC. PSM method selected 285 patients from two cohort(148 in CCRT±IC/AC group,137 in CCRT group).

Purpose: This study aimed to evaluate the prognosis of glioma patients with different molecular subtypes of who treated with intensity-modulated radiation therapy (IMRT).

Methods: We collected 45 glioma patients treated in our hospital between January 2017 and December 2020. All enrolled patients received postoperative IMRT and were divided into two groups based on the Isocitrate dehydrogenase (IDH status).

Osteoclasts (OCs) and regulatory CD4 T cells (CD4 Tregs) are important components in the tumor microenvironment (TME) of osteosarcoma. In this study, we collected six osteosarcoma samples from our previous study (GSE162454). We also integrated a public database (GSE152048), which included single cell sequencing data of 11 osteosarcoma patients.

Background: Tumor infiltrating lymphocytes (TILs), the main component in the tumor microenvironment, play a critical role in the antitumor immune response. Few studies have developed a prognostic model based on TILs in osteosarcoma.

Methods: ScRNA-seq data was obtained from our previous research and bulk RNA transcriptome data was from TARGET database.

In Southeast Asia, the prevalence of nasopharyngeal carcinoma (NPC) is high; however, the molecular mechanism governing the progression of NPC is unclear. The results of the present study revealed upregulation of ring finger protein 219 (RNF219) expression in NPC tissues and cells. Overexpression of RNF219 enhanced NPC cell invasion, migration, and proliferation; whereas knockdown of RNF219 had the opposite effects.

Article Synopsis
  • The study investigates how dose distribution affects the equivalent uniform dose (EUD) model in predicting radiation-induced brain injury in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT).
  • It analyzes data from 103 patients, determining that an optimal volume-effect parameter can be found based on the max area under the curve (mAUC) from receiver operating characteristic (ROC) analyses, revealing that different volumes and dose levels influence predictive accuracy.
  • The findings conclude that the volume-effect parameter in EUD varies with dose distribution, and using a critical-dose-volume EUD approach can enhance predictive capabilities compared to traditional dose/volume metrics.

Article Synopsis
  • A study analyzed 221 patients with stage IA1-IIA1 cervical cancer to determine if adjuvant radiotherapy is needed after laparoscopic hysterectomy.
  • Patients were divided into three groups: those receiving both surgery and radiotherapy (group A), those who had open surgery (group B), and those with laparoscopic surgery alone (group C).
  • Results showed that groups A and B had significantly better 3-year local recurrence-free survival rates compared to group C, suggesting that adjuvant radiotherapy improves outcomes for early-stage cervical cancer, especially in stage IB patients.

Recent studies have shown that some inflammatory markers are associated with the prognosis of solid tumors. This study aims to evaluate the prognosis of glioma patients with or without adjuvant treatment using the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR).All patients who were diagnosed with gliomas at the first and second affiliated hospital of Guangxi Medical University between 2011 and 2020 were included in this study.

Article Synopsis
  • The study examines how half-brain delineation can help predict radiation damage in the temporal lobes of patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiotherapy (IMRT).
  • A retrospective analysis of 220 NPC cases showed significant differences in radiation doses received by the temporal lobes compared to half-brains, with specific dosimetric parameters demonstrating varying degrees of prediction accuracy for temporal lobe injury (TLI).
  • The findings suggest that using half-brain delineation simplifies the contouring process and provides reliable estimates for TLI risk, making it a practical approach for NPC patient treatment planning.

Polyphyllin VII, a compound extracted from the rhizomes of Paris polyphylla, has strong antitumor effects on various human tumor cell lines. However, few studies have reported the possible effect of Polyphyllin VII on human osteosarcoma (OS) cell lines. The present study revealed that Polyphyllin VII promoted OS cell apoptosis and inhibited cell proliferation via upregulating the expression of LC3II, Atg5, Atg7 and the Atg12‑Atg5 complex.

Objective: To investigate the value of CXC subfamily ligands in stage I-III patients with colorectal cancer, in order to find a new predictor for CRC patients.

Methods: We used Gene Expression Omnibus (GEO) database to collect the gene expression of CXC subfamily ligands and corresponding clinical data. The survival analysis was performed by "survival" package of Rsoftware.

Mesoporous calcium-silicon xerogels with a pore size of 15 nm (MCS-15) and pore volume of 1.43 cm(3)/g were synthesized by using 1,3,5-mesitylene (TMB) as the pore-expanding agent. The MCS-15 exhibited good degradability with the weight loss of 50 wt% after soaking in Tris-HCl solution for 56 days, which was higher than the 30 wt% loss shown by mesoporous calcium-silicon xerogels with a pore size of 4 nm (MCS-4).

Background And Methods: A nano calcium-deficient hydroxyapatite (n-CDHA)-multi(amino acid) copolymer (MAC) composite bone substitute biomaterial was prepared using an in situ polymerization method. The composition, structure, and compressive strength of the composite was characterized, and the in vitro degradability in phosphate-buffered solution and preliminary cell responses to the composite were investigated.

Results: The composite comprised n-CDHA and an amide linkage copolymer.
