Background: The surgical treatment of primary intrahepatic bile duct stones is associated with high rates of postoperative complications, stone recurrence, and reoperation. This study aimed to report an 11-year experience in the management of postoperative recurrence of intrahepatic bile duct stones, analyze the causes of the reoperation, and establish appropriate surgical procedures.

Materials And Methods: The records of 148 patients with postoperative recurrence of primary intrahepatic bile duct stones treated from January 2005 to December 2015 were retrospectively reviewed.

Background: Irreversible electroporation (IRE) is a local non-thermal ablative technique which has been suggested as a potential cancer therapy. However, the specific anatomic characteristics of the pancreatic head make it challenging to perform any local ablation in this region. Therefore, the safety and feasibility of IRE in the pancreatic head region should be further explored.

Background: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer in humans after hepatocellular carcinoma and a rare epithelial malignancy that results in a poor prognosis. According to the Liver Cancer Study Group of Japan classification, ICC can be divided into three types: Mass-forming (MF) type, periductal-infiltrating (PI) type, and intraductal-growth type. The MF type is the most common, accounting for 57.

Background: In recent years, we created and employed a new anastomosis method, "bridging" pancreaticogastrostomy, to treat patients with extremely severe pancreatic injury. This surgery has advantages such as short length of surgery, low secondary trauma, rapid construction of shunts for pancreatic fluid, preventing second surgeries, and achieving good treatment outcomes in clinical practice. However, due to the limited number of clinical cases, there is a lack of strong evidence to support the feasibility and safety of this surgical procedure.

The incidence of gastrointestinal (GI) tumors is increasing year by year, and its pathogenesis is closely related to the intestinal flora. At present, the use of antibiotics is very common in the clinic. And cancer patients with low immunity are vulnerable to all sorts of infections, such as respiratory tract infections and urinary tract infections.

Two new p-terphenyls, strepantibins A and B (1 and 2), along with the first representative of a naturally occurring bisphenyltropone, strepantibin C (3), were characterized from a Streptomyces sp. associated with the larvae of the mud dauber wasp Sceliphron madraspatanum. Their structures were determined by high-resolution electrospray ionization mass spectrometry, NMR, and X-ray crystallography data interpretation.

Article Synopsis
  • - The study aims to compare the survival outcomes of patients with right-sided primary (RSP) tumors versus left-sided primary (LSP) tumors undergoing hepatic arterial infusion chemotherapy (HAIC) for metastatic colorectal cancer.
  • - A total of 168 patients were analyzed, revealing similar response rates and disease control rates for both tumor sides; median overall survival was 16.3 months for LSP patients and 9.3 months for RSP patients.
  • - The results show no significant survival difference between LSP and RSP patients post-treatment, indicating a need for further research to confirm these observations.

Ivalin, an eudesmane-type sesquiterpene compound, was isolated from the Chinese herb Carpesium divaricatum in our chemistry group. In this study, we investigated the anti-migration and anti-invasion activities and underlying mechanisms of Ivalin in breast cancer cells in vitro. Cell viability was evaluated using the MTT assay, Western blotting was used to determine the expression of E-cadherin, N-cadherin, vimentin and ZEB1, and mRNA levels were analyzed by qPCR.

Article Synopsis
  • The study aimed to assess the effectiveness and safety of two types of chemotherapy (raltitrexed versus 5-fluorouracil) delivered through hepatic artery infusion for treating liver metastases from colorectal cancer in patients who didn't respond to previous treatments.
  • A total of 42 patients were analyzed, with 24 receiving 5-fluorouracil and 18 receiving raltitrexed; results indicated no significant survival difference between the two treatment groups, with median survival times of 20.6 months for raltitrexed and 15.4 months for 5-fluorouracil after starting HAIC.
  • Side effects varied, with more cases of leuk

Small cell lung cancer (SCLC) is a neuroendocrine tumor with the potential to secrete various peptides or hormones that can lead to paraneoplastic syndromes, such as Ectopic Cushing syndrome (ECS). Because of the aggressive nature of the syndrome and its atypical features, ECS in small-cell lung cancer is difficult to diagnose and has a poor prognosis. We report a case of a 74-year-old male patient who presented with severe hypokalemia, proximal muscle weakness, peripheral edema, metabolic alkalosis, and worsening hyperglycemia.

Gall bladder carcinoma (GBC) is the seventh most common cancer across the globe and the most common malignancy of the biliary tract. Most GBC related deaths occur due to secondary progression and metastasis to distant organs. Epithelial-mesenchymal transition (EMT) is an important pre-requisite for tumor metastasis, however its mechanism in GBC has not yet been defined.

The alteration in cellular Ca(2+) homeostasis is one of the key mechanisms contributing to secondary neuronal damage and altered physiology during the process of traumatic brain injury (TBI). However, there is considerable uncertainty about the efficacy of calcium channel blockers in randomized, controlled, clinical trials. In the physiological condition, cellular Ca(2+) homeostasis occurs through repetitive bursts of rising intracellular Ca(2+) that, sometimes are referred to as Ca(2+) oscillations.
