Diagnosis and Analysis of Transabdominal and Intracavitary Ultrasound in Gynecological Acute Abdomen.

In order to explore the effective diagnosis method of gynecological acute abdomen, this paper takes hospital gynecological acute abdomen patients as samples and selects gynecological acute abdomen patients admitted to the hospital to be included in this study. They are divided into transabdominal ultrasound group, intracavitary ultrasound group, and combined group. Moreover, this paper uses mathematical statistics to carry out sample statistics.

Identification of messenger and long noncoding RNAs associated with gallbladder cancer via gene expression profile analysis.

The present study aimed to investigate the long noncoding RNAs (lncRNAs) and messenger RNAs (mRNAs) involved in the progression of gallbladder cancer and explore the potential physiopathologic mechanisms of gallbladder cancer in terms of competing endogenous RNAs (ceRNAs). The original lncRNA and mRNA expression profile data (nine gallbladder cancer tissues samples and nine normal gallbladder samples) in GSE76633 was downloaded from the Gene Expression Omnibus database. Differentially expressed mRNAs and lncRNAs between gallbladder cancer tissue and normal control were selected and the pathways in which they are involved were analyzed using bioinformatics analyses.

Effect of microRNA-27a-5p on apoptosis and inflammatory response of pancreatic acinar cells in acute pancreatitis by targeting PTEN.

To investigate the apoptosis and inflammatory response of microRNA-27a-5p (miR-27a-5p) in pancreatic acinar cells of acute pancreatitis (AP) and its related mechanisms. Rat pancreatic acinar cell line AR42J was treated with caerulein (10nmol/L) to construct an acute pancreatitis cell model. Quantitative real-time polymerase chain reaction was performed to measure the expression of miR-27a-5p; The miR-27a-5p mimic was transfected into cell, and the apoptosis rate of the cells was detected by flow cytometry; The levels of TNF-α, IL-1, and IL-6 in the culture supernatant were determined by enzyme-linked immunosorbent assay; TargetScans database predicted and dual luciferase reporter gene assay verified the relationship between miR-27a-5p and the phosphatase and tensin homolog deleted on chromosome 10 (PTEN); The recovery experiment explored the apoptosis and the effects of inflammatory responses.

Upregulated lncRNA-UCA1 contributes to metastasis of bile duct carcinoma through regulation of miR-122/ and activation of the ERK/MAPK signaling pathway.

In the present study, we aimed to identify specific lncRNAs and miRNAs, as well as mRNAs, involved in bile duct carcinoma (BDC) and to further explore the way in which lncRNA UCA1 regulates cell metastasis ability. Differentially expressed RNAs were screened out from the TCGA database. In experiments, qRT-PCR was used to measure lncRNA UCA1, miR-122 and expression.

Metformin inhibits endothelial progenitor cell migration by decreasing matrix metalloproteinases, MMP-2 and MMP-9, via the AMPK/mTOR/autophagy pathway.

The aim of the present study was to investigate the effect of metformin on endothelial progenitor cell (EPC) migration and to explore the possible mechanisms. EPCs were treated with metformin, and the migration of EPCs was evaluated by wound healing and Matrigel invasion assays. We also examined the expression levels of of MMP-2 and MMP-9 in EPCs with or without metformin treatment via RT-PCR and western blot analysis, and activities of MMP-2 and MMP-9 in EPCs under different conditions was examined by zymography.

Overexpression of CD39 and high tumoral CD39⁺/CD8⁺ ratio are associated with adverse prognosis in resectable gastric cancer.

CD39/ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1) is a cell surface-located, rate-limiting enzyme in the generation of adenosine, and plays a crucial role in tumor development. We examined co-expression of CD39 and CD8in gastric cancer (GC) and showed that the expression of CD39 and CD8 increased significantly in tumor tissues compared to paired peritumor tissues. The expression of tumoral CD39 (tCD39), but not tumoral CD8 (tCD8), was related to overall survival.

The Value of Performing Early Non-enhanced CT in Developing Strategies for Treating Acute Gallstone Pancreatitis.

Background: The purpose of this study is to assess the value of early abdominal non-enhanced computed tomography (NECT) in developing strategies for treating acute gallstone pancreatitis (AGP).

Methods: AGP patients underwent NECT within 48 h after symptom onset to determine the presence of peripancreatic fluid collection, gallstones, and common bile duct stones. Patients with mild AGP who had neither organ failure by clinical data nor peripancreatic fluid collection by NECT (classified as grade A, B, or C based on the Balthazar CT grading system) were randomized to undergo an early laparoscopic cholecystomy (ELC; LC performed within 7 days after a pancreatitis attack, without waiting for symptom resolution) or late laparoscopic cholecystomy (LLC; LC performed ≥ 7 days following an attack, with the patient being completely free of AGP symptoms).

Ampulla dilation with different sized balloons to remove common bile duct stones.

Aim: To assess the outcomes of ampulla dilation with different sized balloons to remove common bile duct (CBD) stones.

Methods: Patients (n = 208) were divided into five groups based on the largest CBD stone size of < 5, 6-8, 8-12, 12-14, and > 14 mm. Patients underwent limited endoscopic sphincterotomy (EST) alone or limited EST followed by endoscopic papillary balloon dilation with 8, 10, 12 and 14 mm balloons, such that the size of each balloon did not exceed the size of the CBD.

Dynamic activity of NF-kappaB in multiple trauma patients and protective effects of ulinastain.

Objective: To investigate the dynamic activity of NF-kappaB at the early stage of injury in multiple trauma patients and the protective effects of ulinastain.

Methods: From January 2008 to May 2010, patients with multiple traumas admitted to our emergency department were enrolled in this study. Their age varied from 20-55 years.

Duodenoscopy in treatment of acute gallstone pancreatitis.

Objective: To probe the potential use of duodenoscopy in the diagnosis and treatment of acute gallstone pancreatitis (GP).

Methods: Fourty-five patients with acute GP were randomly divided into endoscopic retrograde cholangiopancreatography (ERCP) group (n=20) and non-ERCP group (n=25). Each group was subdivided into mild and severe groups according to APACHE II scores.
