Preventing postsurgical colorectal cancer relapse: A hemostatic hydrogel loaded with METTL3 inhibitor for CAR-NK cell therapy.

Colorectal cancer (CRC) recurrence post-surgery remains a major challenge. While Chimeric Antigen Receptor (CAR)-engineered natural killer (NK) cells hold immense therapeutic potential, their intratumoral infiltration ability remains limited, hampering efficacy. Building upon prior research suggesting that chemokines like C-X-C motif chemokine ligand 9 (CXCL9) and C-X-C motif chemokine ligand 10 (CXCL10) recruit CAR-NK cells, we hypothesized that tumor cell m6A methylation, regulated by Methyltransferase-like 3 (METTL3), influences chemokine secretion.

[ Amplification of NK Cells from Feeder Layer Cells Expressing IL-21].

Objective: To investigate the effect of feeder layer cells expressing interleukin (IL)-21 on the amplification of NK cells .

Methods: The K562 cell line with IL-21 expression on its membrane was constructed by electroporation, and co-cultured with NK cells after inactivation. The proliferation of NK cells was observed.

Construction of a tumor mutational burden-derived LncRNA prognostic computational framework associated with therapy sensitivity in skin cutaneous melanoma.

Background: Skin cutaneous melanoma (SKCM) poses a significant public health challenge due to its aggressive nature and limited treatment options. To address this, the study introduces the Tumor Mutational Burden-Derived Immune lncRNA Prognostic Index (TILPI) as a potential prognostic tool for SKCM.

Methods: TILPI was developed using a combination of gene set variation analysis, differential expression analysis, and COX regression analysis.

Long-term outcomes of single-incision plus one-port laparoscopic surgery versus conventional laparoscopic surgery for rectosigmoid cancer: a randomized controlled trial.

Background: Though our previous study has demonstrated that the single-incision plus one-port laparoscopic surgery (SILS + 1) is safe and feasible for sigmoid colon and upper rectal cancer and has better short-term outcomes compared with conventional laparoscopic surgery (CLS), the long-term outcomes of SILS + 1 remains uncertain and are needed to evaluated by an RCT.

Methods: Patients with clinical stage T1-4aN0-2M0 rectosigmoid cancer were enrolled. The participants were randomly assigned to either SILS + 1 (n = 99) or CLS (n = 99).

Pelvic Floor Peritoneum Closure Reduces Severe Postoperative Complications in Rectal Cancer Patients After Laparoscopic Anterior Rectal Resection.

Background: Laparoscopic anterior rectal resection (LAR) is a commonly performed surgery for rectal cancer patients. Pelvic floor peritoneum closure (PC), a vital procedure in conventional anterior rectal resection, is not routinely performed in LAR.

Study Design: A total of 1118 consecutive patients with rectal cancer receiving LAR were included in this retrospective study.

Effect of Argatroban Plus Intravenous Alteplase vs Intravenous Alteplase Alone on Neurologic Function in Patients With Acute Ischemic Stroke: The ARAIS Randomized Clinical Trial.

Importance: Previous studies suggested a benefit of argatroban plus alteplase (recombinant tissue-type plasminogen activator) in patients with acute ischemic stroke (AIS). However, robust evidence in trials with large sample sizes is lacking.

Objective: To assess the efficacy of argatroban plus alteplase for AIS.

Effect of single-incision plus one port laparoscopic surgery assisted with enhanced recovery after surgery on colorectal cancer: study protocol for a single-arm trial.

Background: Studies have proved that the enhanced recovery after surgery (ERAS) protocol can significantly improve the recovery course of patients during the perioperative period. The application of minimally invasive surgery is a critical component of ERAS protocol. Single-incision plus one port laparoscopic surgery (SILS plus one) could achieve further minimally invasive surgical results than conventional laparoscopic surgery (CLS).

CT Appearance Pattern After Stereotactic Body Radiation Therapy Predicts Outcomes in Early-Stage Non-Small-Cell Lung Cancer.

Backgrounds: Computed tomography (CT) appearance pattern after lung tumor stereotactic body radiation therapy(SBRT) might predicts survival. This study aimed to investigate the correlation between CT appearance pattern after SBRT and outcomes in patients with early-stage non-small-cell lung cancer (NSCLC).

Methods: Clinical data of inoperable patients with early-stage NSCLC undergoing SBRT were retrospectively analyzed from 2012 to 2015 at the Zhejiang Cancer Hospital.

Recombinant human insulin-like growth factor-1 promotes osteoclast formation and accelerates orthodontic tooth movement in rats.

Background: IGF-1 may be an important factor in bone remodeling, but its mechanism of action on osteoclasts during orthodontic tooth movement is complex and unclear.

Methodology: The closed-coil spring was placed between the left maxillary first molar and upper incisors with a force of 50 g to establish an orthodontic movement model. Eighty SD rats were randomized to receive phosphate buffer saline or 400 ng rhIGF-1 in the lateral buccal mucosa of the left maxillary first molar every two days.

Exosomes are the novel players involved in the beneficial effects of exercise on type 2 diabetes.

Exosomes contain regulatory signals such as lipids, proteins, and nucleic acids which can be transferred to adjacent or remote cells to mediate cell-to-cell communication. Exercise is a positive lifestyle for metabolic health and a nonpharmacological treatment of insulin resistance and metabolic diseases. Moreover, exercise is a stressor that induces cellular responses including gene expression and exosome release in various types of cells.

Somatic mutation profiling of liver and biliary cancer by targeted next generation sequencing.

Liver and biliary cancers are highly lethal cancer types lacking effective treatments. The somatic mutations, particularly those with low mutant allele frequencies, in Chinese patients with liver and biliary cancer have not been profiled, and the frequency of patients benefiting from targeted therapy has not been studied. The present study evaluated the tumor tissues of 45 Chinese patients with hepatocellular carcinoma (HCC) and 12 Chinese patients with biliary tract cancer (BTC) by targeted next generation sequencing, with an average coverage of 639×, to identify alterations in 372 cancer-related genes.

Repetitive magnetic stimulation promotes the proliferation of neural progenitor cells via modulating the expression of miR-106b.

Increasing evidence shows that repetitive transcranial magnetic stimulation (rTMS) promotes neurogenesis and the expression of microRNA (miR)‑106b. The present study investigated whether rTMS promotes the proliferation of neural progenitor cells (NPCs) and whether the effect is associated with the expression of miR‑106b. NPCs were cultured from the rat hippocampus and exposed to rTMS daily, comprising 1,000 stimuli for 3 days at 10 Hz, with 1.

[Effect of local injection of rhTGF-α1 on osteoclasts during orthodontic tooth movement in rats].

Purpose: To investigate the effect of exogenous TGF-β1 on improving periodontal tissues remodeling during orthodontic tooth movement in rats.

Methods: Eighty male SD rats were randomly divided into 2 groups. Rats in the experimental group were injected respectively with rhTGF-β1 in dosages of 0.

Perspectives on a combined test of multi serum biomarkers in China: towards screening for and diagnosing hepatocellular carcinoma at an earlier stage.

China has 50% of the worldwide hepatocellular carcinoma (HCC) cases, and the HBV-related cases accounts for approximately 85%. Over the past few decades, although a series of standardized management methods for HCC has been implemented in China, most HCC patient in China still suffered from advanced-stage disease, in consequence, reducing the opportunity of curable treatment that can be offered to achieve long-term disease-free survival for HCC patient. Accordingly, strategies including screening and diagnose HCC at an earlier stage are urgently needed in China.

Ex-situ liver surgery without veno-venous bypass.

Aim: To evaluate the results of hepatic resection with ex-situ hypothermic perfusion and without veno-venous bypass.

Methods: In 3 patients with liver tumor, the degree of the inferior vena cava and/or main hepatic vein involvement was verified when the liver was dissociated in the operation. It was impossible to resect the tumors by the routine hepatectomy, so the patients underwent ex-situ liver surgery, vein cava replacement and hepatic autotransplantation without veno-venous bypass.
