Promotion of hepatocellular carcinoma stemness and progression by abnormal spindle-like microcephaly-associated protein via the Wnt/β-catenin pathway.

Background: Cancer stem cells (CSCs) play a crucial role in tumor recurrence and metastasis, which are the primary causes of death in patients with hepatocellular carcinoma (HCC). Currently, no drug effectively blocks the recurrence and metastasis of liver cancer, leading to a poor prognosis for patients. To enhance treatment outcomes, there is an urgent need to investigate the molecular mechanisms behind the recurrence and progression of liver cancer, with the aim of identifying effective therapeutic targets.

Exosome biogenesis: machinery, regulation, and therapeutic implications in cancer.

Exosomes are well-known key mediators of intercellular communication and contribute to various physiological and pathological processes. Their biogenesis involves four key steps, including cargo sorting, MVB formation and maturation, transport of MVBs, and MVB fusion with the plasma membrane. Each process is modulated through the competition or coordination of multiple mechanisms, whereby diverse repertoires of molecular cargos are sorted into distinct subpopulations of exosomes, resulting in the high heterogeneity of exosomes.

Effect of combined treatment with cyclophosphamidum and allicin on neuroblastoma-bearing mice.

Objective: To evaluate the efficacy of allicin combined with cyclophosphamide on neuroblastoma (NB)-bearing mice and explore the immunological mechanism in it.

Methods: A total of 30 NB-bearing mice were equally randomized into model group, cyclophosphamide group and combined therapy group, 10 nudemice were set as normal saline (NS) group. Cyclophosphamide group and combined therapy group were weekly injected with 60 mg/kg cyclophosphamide for four weeks; besides, combined therapy group was given with allicin (10 mg/kg/d) by gastric perfusion for 4 weeks; model group and NS group were given with the same volume of NS.

Pancreaticogastrostomy versus pancreaticojejunostomy after pancreaticoduodenectomy: a meta-analysis of randomized controlled trials.

Background: The best reconstruction method for the pancreatic remnant after pancreaticoduodenectomy remains debatable. We aimed to investigate the perioperative outcomes of 2 popular reconstruction methods: pancreaticogastrostomy and pancreaticojejunostomy.

Data Sources: Randomized controlled trials comparing pancreaticogastrostomy versus pancreaticojejunostomy were identified from literature databases (MEDLINE/PubMed, EMBASE, Web of Science, Cochrane Library).

An updated meta-analysis on the association of X-ray repair cross complementing group 1 codon 399 polymorphism with hepatocellular carcinoma risk.

Background: A number of studies have reported the association of X-ray repair cross-complementing group 1 (XRCC1) Arg399Gln polymorphism with susceptibility to hepatocellular carcinoma (HCC). However, the results were inconsistent and inconclusive. The aim of this study was to comprehensively explore the association of XRCC1 Arg399Gln variant with HCC risk.

Induction of ER stress protects gastric cancer cells against apoptosis induced by cisplatin and doxorubicin through activation of p38 MAPK.

We investigated the role of endoplasmic reticulum (ER) stress response and p38 MAPK pathways in the resistance of gastric cancer cells to chemotherapy. Pretreatment of the gastric cancer cells with the ER stress inducer drastically decreased the apoptotic rate induced by cisplatin or doxorubicin. Induction of ER stress also led to the activation of p38.

[Binding fistulojejunostomy for the treatment of external pancreatic fistula].

Objective: To evaluate the safety and feasibility of binding fistulojejunostomy, a new operative procedure, in the treatment of external pancreatic fistula.

Methods: Eight patients suffering from external pancreatic fistula, 4 males and 4 females, aged 49 (22 approximately 69), underwent binding fistulojejunostomy: 2 cm-length of fistula was isolated and a tube was inserted therein, the jejunum was transected and the distant cut end was everted for the length of 3 cm, the mucosa of the everted jejunum was destroyed with carbolic acid, the everted mucosa of jejunum and the fistula were brought together and sutured with silk, the everted jejunum was then turned back to wrap over the fistula, a silk tie was lopped around the entire circumference of the anastomosis, and lastly, the tube was led out of the abdominal wall.

Results: all 8 patients recovered smoothly without pancreatic leakage and other complications.

[How brain-dead state affects the hepatic morphology and function of Ba-Ma mini pigs and its mechanism].

Objective: To investigate the impact of brain death (BD) on the morphology and function of liver.

Methods: Fifteen Ba-ma minipigs were randomly divided into 3 equal groups: brain death group (Group B) made into BD models by increasing the intracranial pressure; breviscapine pretreatment group (Group P), with breviscapine 2.5 mg x kg(-1) given intravenous drip 1-2 hours after the successful establishment of BD model; and control group (Group C) undergoing operation similar to that in Group B but without increasing the intracranial pressure.

Protection effect of triptolide to liver injury in rats with severe acute pancreatitis.

Background: The high mortality of patients with severe acute pancreatitis (SAP) is due to multiorgan dysfunction. The mechanisms of SAP are still obscure. The aim of this study was to investigate the role of nuclear factor-kappa B (NF-kappaB) activation in rats with SAP associated with liver injury and the protection effect of triptolide against liver injury in rats with SAP.
