Establishment and validation of a nomogram containing cytokeratin fragment antigen 21-1 for the differential diagnosis of intrahepatic cholangiocarcinoma and hepatocellular carcinoma.

Background: Our study aimed to develop a nomogram incorporating cytokeratin fragment antigen 21-1 (CYFRA21-1) to assist in differentiating between patients with intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC).

Methods: A total of 487 patients who were diagnosed with ICC and HCC at Qilu Hospital of Shandong University were included in this study. The patients were divided into a training cohort and a validation cohort based on whether the data collection was retrospective or prospective.

subtotal spleen resection combined with selective pericardial devascularization for the treatment of portal hypertension.

Background: Hypersplenism and esophageal varices bleeding are the major complications of portal hypertension (PHT). In recent years, increasing attention has been given to spleen preservation operations. The mode and long-term effects of subtotal splenectomy and selective pericardial devascularization for PHT remain controversial.

Management of hepatocellular carcinoma patients with portal vein tumor thrombosis: A narrative review.

Background: Hepatocellular carcinoma (HCC) is one of the main reasons for malignancy-related death. Portal vein tumor thrombosis (PVTT) is the most common form of macrovascular invasion related to HCC occurring in 10%-60% of patients. HCC with PVTT is usually characterized by worsening liver function, vulnerability to blood metastasis, higher incidence of complications associated with portal hypertension, and intolerance to treatment when compared with that without PVTT.

Functional predication of differentially expressed circRNAs/lncRNAs in the prefrontal cortex of Nrf2-knockout mice.

In the central nervous system, nuclear factor erythroid-2-related factor 2 (Nrf2) protects neurons from oxidant injury, thereby ameliorating neurodegeneration. We explored the key circular RNAs (circRNAs) and long non-coding RNAs (lncRNAs) involved in Nrf2-induced neuroprotection. We used microarrays to examine the circRNAs (DEcircRNAs), lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) differentially expressed between Nrf2 (+/+) and Nrf2 (-/-) mice and identified DEcircRNA/DElncRNA-miRNA-DEmRNA interaction networks.

A novel oncolytic adenovirus inhibits hepatocellular carcinoma growth.

Objective: To evaluate the inhibitory role of a novel oncolytic adenovirus (OA), GP73-SphK1sR-Ad5, on the growth of hepatocellular carcinoma (HCC).

Methods: GP73-SphK1sR-Ad5 was constructed by integrating Golgi protein 73 (GP73) promoter and sphingosine kinase 1 (SphK1)-short hairpin RNA (shRNA) into adenovirus serotype 5 (Ad5), and transfecting into HCC Huh7 cells and normal human liver HL-7702 cells. The expression of SphK1 and adenovirus early region 1 (E1A) was detected by quantitative real-time PCR (qRT-PCR) and western blot, respectively.

Differential Expression Profiles and Functional Prediction of Circular RNAs and Long Non-coding RNAs in the Hippocampus of Nrf2-Knockout Mice.

Background: Nrf2 (nuclear factor, erythroid 2 like 2) is believed to play a major role in neurodegenerative diseases. The present study attempts to investigate the hippocampal circRNA and lncRNA expression profiles associated with Nrf2-mediated neuroprotection.

Methods: The hippocampal mRNA, circRNA and lncRNA expression profiles of Nrf2 (-/-) mice were determined by a microarray analysis.

Proteinase-activated receptor 2 promotes tumor cell proliferation and metastasis by inducing epithelial-mesenchymal transition and predicts poor prognosis in hepatocellular carcinoma.

Aim: To clarify the role of proteinase-activated receptor 2 (PAR2) in hepatocellular carcinoma, especially in the process of metastasis.

Methods: PAR2 expression levels were assessed by qRT-PCR and immunohistochemistry (IHC) in patient tissues and in hepatocellular carcinoma cell lines SMMC-7721 and HepG2. Cell proliferation and metastasis were assessed both and .

[Ecological risk assessment and its management of Bailongjiang watershed, southern Gansu based on landscape pattern].

Watershed ecological risk assessment is an important research subject of watershed ecological protection and environmental management. Research on the ecological risk focuses on addressing the influence of human activities and its spatial variation at watershed scale is vital to policy-making to control the impact of human activity and protocols for sustainable economic and societal development. A comprehensive ecological environment index, incorporating a landscape index and an assessment of ecological vulnerability, was put forward to assess the spatio-temporal characteristics of ecological risk of the Bailongjiang watershed, southern Gansu Province, Northwest China.

Analysis of the causes and clinical characteristics of jejunoileal hemorrhage in China: a multicenter 10 year retrospective survey.

Background: A retrospective study was performed to assess the causes, diagnostic methods for, and clinical features of, jejunoileal hemorrhage in Shandong province, China and to derive recommendations for management of this condition from these data.

Methods: We performed a retrospective systematic collection of data from between January 1999 and December 2008 in seven cities in Shandong province, China, identified 72 patients with jejunoileal hemorrhage and analyzed the relevant clinical data.

Results: Overall, tumors were the most common cause of jejunoileal hemorrhage (42 patients, 58.

Analysis of clinical features of acute pancreatitis in Shandong Province, China.

Aim: To investigate and obtain a more comprehensive view of the etiology and clinical features of acute pancreatitis in China.

Method: The study comprised 1471 patients in 10 cites of China who were admitted to hospitals for acute pancreatitis from January 1992 to December 2002. Data for each patient were collected on a standardized form.

Analysis of the clinical features of recurrent acute pancreatitis in China.

Background: Since few systematic studies have focused on recurrent acute pancreatitis in China, we sought to investigate its clinical features, including etiological factors and relative frequency.

Methods: Patients were selected from a total 1471 patients with acute pancreatitis in ten cities of China. All had been admitted to a hospital with an attack of acute pancreatitis between January 1992 and December 2002.

[The clinical features of acute pancreatitis in 10 cities in Shandong Province].

Objective: To investigate and obtain a more comprehensive view of the etiology and clinical features of acute pancreatitis (AP) in Shandong Province.

Methods: 1471 cases admitted to hospital for AP were studied and collected from the ten cities of Shandong Province from January 1992 to December 2002 retrospectively. Data of each enrolled patient was recorded in a standardized form.
