Objective: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy because it is often diagnosed at a late-stage. Signal transducer and activator of transcription 5 (STAT5) is a transcription factor implicated in the progression of various cancer types. However, its role in KRAS-driven pancreatic tumourigenesis remains unclear.

Objective: To investigate the clinical potential and safety of Moluodan to reverse gastric precancerous lesions.

Methods: Patients aged 18-70 years diagnosed with moderate-to-severe atrophy and/or moderate-to-severe intestinal metaplasia, with or without low-grade dysplasia, and negative for Helicobacter pylori were recruited in this randomized, double-blind, parallel-controlled trial. The primary outcome was the improvement of global histological diagnosis at 1-year follow-up endoscopy using the operative link for gastritis assessment, the operative link for gastric intestinal metaplasia assessment, and the disappearance rate of dysplasia.

Article Synopsis
  • - The study investigated the use of specific bacteria found in feces as potential early diagnostic markers for gastric cancer (GCa), focusing on samples from 1043 patients in China.
  • - Significant findings included the detection of two bacteria, Streptococcus anginosus and Streptococcus constellatus, which showed higher levels in both gastric cancer tissues and fecal samples, making them reliable indicators for both early and advanced GCa.
  • - The fecal bacterial signature exhibited high sensitivity and specificity in distinguishing early GCa from more advanced stages, suggesting it could serve as a noninvasive method for early cancer detection.

Objectives: To assess the clinical outcomes of using a bipedicle advancement flap to cover the skin defects after digital mucous cyst (DMC) excision.

Methods: Data for 15 patients (18 fingers) with DMC, admitted to the Department of Orthopaedics and Surgery of the Affiliated Zhongshan Hospital of Dalian University from January 2016 to January 2018, were analyzed retrospectively. This study included 4 men and 11 women, with a mean age of 64 ± 7.

Background: Liver fibrosis is a key phase that will progress to further injuries such as liver cirrhosis or carcinoma. This study aimed to investigate whether transplantation of bone marrow mesenchymal stromal cells (BM-MSCs) can attenuate liver fibrosis in mice and the underlying mechanisms based on the regulation of macrophage subtypes.

Methods: A liver fibrosis model was induced by intraperitoneal (i.

It is uncommon for tire explosion related injuries on the lower extremity. The bilateral lower extremities were injured by tire explosion when the patient was seated in a bus. She sustained an open fracture with partial bone loss in the right calcaneus (a comminuted fracture in the right ankle joint) and a closed comminuted fracture in the left tibia and fibula.

Purpose: To evaluate the clinical value of computed tomography angiography (CTA) in reducing the risk of hemorrhage associated with mini-percutaneous nephrolithotomy (PCNL).

Materials And Methods: A total of 158 patients with renal or ureter stones who had undergone mini-percutaneous nephrolithotomy were retrospectively enrolled into this study from May of 2011 to April of 2014. Group 1 (65 patients) underwent computed tomography angiography, and Group 2 (93 patients) underwent non-contrast CT.

Objective: To screen and verify differentially expressed genes in prostate cancer.

Methods: Using DNA microarray, we screened differentially expressed genes in prostate cancer tissue and its adjacent tissue followed by verification by PCR.

Results: A total of 1 444 genes were found to be differentially expressed (differentiation ≥ 1.

Trastuzumab is the first molecular targeting drug to increase the overall survival rate in advanced gastric cancer. However, it has also been found that a high intrinsic or primary trastuzumab resistance exists in some proportion of gastric cancer patients. In order to explore the mechanism of resistance to trastuzumab, firstly we investigated the expression of MUC1 (membrane-type mucin 1) in gastric cancer cells and its relationship with drug-resistance.

Objective: To study the synergetic killing effects of external magnetic fields combined with the photodynamic action of porphyrin-dextran iron oxide magnetic nanoparticles (PDMN) on human bladder cancer cells in vitro.

Methods: The PDMN were produced by using the chemical co-precipitation and redox process and the physicochemical properties were characterized. Methyl thiazolyl tetrazolium (MTT) and flow cytometry were used to determine the effects of photodynamic therapy of PDMN combined with external pulsed electromagnetic fields (5 mT) on killing human bladder cancer BIU-87 cells respectively.

In order to obtain the stable PCR combinations for silkies genetic analysis, multiplex PCR was used and its reaction condition was optimized. Five combinations of multiplex PCR with good effects were obtained from eighteen microsatellite markers. Three of them were quadruplex-PCRs, and two were triplex-PCRs.

Twenty microsatellite markers selected from the chicken GENBANK were analyzed for polymorphism in two new Silkies laying breeds. Allele frequencies were tested by the auto scan on ABI 3100-Avant Genetic Analyzer. The results suggested that the optimization test of multiplex PCR was successful and 18 pairs of microsatellite DNA markers were polymorphic.

To describe changes in activities of daily living (ADL) of community-dwelling Beijing elderly people, observed for 8 years, and to identify the demographic characteristics that predict the functional change. Four sets of interview data from 1992 to 2000 were used to evaluate changes among Beijing elderly aged 55 years and over. Results revealed that prevalence of disability increased from 3.
