The Chinese Society of Hepatology position statement on the redefinition of fatty liver disease.

Fatty liver disease associated with metabolic dysfunction is of increasing concern in mainland China, the world's most populous country. The incidence of fatty liver disease is highest in China, surpassing the incidence in European countries and the USA. An international consensus panel recently published an influential report recommending a novel definition of fatty liver disease associated with metabolic dysfunction.

Scutellarin inhibits hypoxia-induced epithelial-mesenchymal transition in bladder cancer cells.

Scutellarin, an active component of flavonoid, displays a variety of physiological actions and has been applied for the treatment of diverse diseases including hypertension and cerebral infarction as well as cerebral thrombosis. In recent time, Scutellarin has been demonstrated to possess the anticancer activity. But the biological significance of Scutellarin in bladder cancer (BC) remains to be elucidated.

Expression and Significance of Th17 Cells and Related Factors in Patients with Autoimmune Hepatitis.

Objective: This study aims to investigate the expression and clinical significance of Th17 cells and related factors in peripheral blood of patients with Autoimmune Hepatitis (AIH).

Methods: A retrospective selection of 100 patients with AIH were included as a study group, and 100 healthy volunteers in the outpatient clinic were selected as the control group. The levels of IL- 17, IL-6, IL-21 and TNF-α in peripheral blood of all subjects were detected by enzyme-linked immunosorbent assay and the frequency of Th17 cells and Treg cells was detected by flow cytometry.

Glaucocalyxin B protects against oxygen-glucose-deprivation/reperfusion-induced neuronal injury in PC-12 cells.

Oxidative stress has been implicated in the development of cerebral ischemia/reperfusion (I/R) injury. Glaucocalyxin B (GLB), one of five ent-kauranoid diterpenoids, was reported to possess neuroprotective activity. However, the effect of GLB on oxygen-glucose-deprivation/reperfusion (OGD/R)-induced cell injury in PC-12 cells has not been explored.

Piperlongumine inhibits angiotensin II-induced extracellular matrix expression in cardiac fibroblasts.

Piperlongumine (PL), a single component isolated from Piper longum, has been reported to possess anti-inflammatory, antibacterial, antiangiogenic, antioxidant, antitumor, and antidiabetic activities. However, its role in cardiac fibrosis remains to be clarified. Therefore, we determined the effects of PL on cardiac fibroblasts (CFs) proliferation, and extracellular matrix (ECM) production under angiotensin II (Ang II) conditions, and further investigated the underlying molecular mechanism.

Endostar (rh-endostatin) versus placebo in combination with vinorelbine plus cisplatin chemotherapy regimen in treatment of advanced non-small cell lung cancer: A meta-analysis.

Background: This meta-analysis was conducted to investigate the efficacy and safety of Endostar (rh-endostatin) versus a placebo in combination with a vinorelbine plus cisplatin (NP) chemotherapy regimen for the treatment of advanced non-small cell lung cancer (NSCLC).

Methods: Two reviewers independently searched Medline, PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, ASCO, ESMO, the Web of Science, and CNKI databases to locate relevant controlled clinical trials. The treatment efficacy and drug-related toxicity of NP + Endostar (NPE) and NP groups were pooled through meta-analysis according to random or fixed effect models.

LncRNA NEAT1 contributes to paclitaxel resistance of ovarian cancer cells by regulating ZEB1 expression via miR-194.

Background: Chemoresistance is one of the major obstacles for cancer therapy in the clinic. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been reported as an oncogene in most malignancies such as lung cancer, esophageal cancer, and gastric cancer. This study is designed to investigate the function of NEAT1 in paclitaxel (PTX) resistance of ovarian cancer and its potential molecular mechanism.

XRCC2-Deficient Cells are Highly Sensitive to 5-Fluorouracil in Colorectal Cancer.

Background/aims: Inhibition of the repair of 5-fluorouracil (5-FU)-induced DNA lesions may improve the responses of tumors to anticancer agents. XRCC2 is a key factor in DNA repair. However, the role of XRCC2 in the chemoresistance of colorectal cancer (CRC) treated with 5-FU remains unclear.

miRNA-129-5p suppresses cell proliferation and invasion in lung cancer by targeting microspherule protein 1, E-cadherin and vimentin.

Downregulation of microRNA-129 (miR-129) has been described in various types of cancer, however, the significance of miR-129 in lung cancer has not been investigated. The present study, for the first time, determined miR-129-5p expression levels in both lung cancer cell lines and primary lung cancer tissues and also studied the effect of miR-129-5p on the proliferation and invasiveness of lung cancer cells. The results showed that miR-129-5p expression was significantly reduced in both lung cancer cell lines and primary lung cancer tissues (P<0.

[Therapeutic efficacy and quality of life investigation of traditional Chinese medicine-based therapy of chronic hepatitis B-related liver fibrosis].

Objective: To prospectively evaluate the efficacy of a traditional Chinese medicine (TCM)-based therapy for treating liver fibrosis in patients with chronic hepatitis B (CHB), and to investigate the patients' perception of the treatment's effects on quality of life (QoL).

Methods: A total of 430 patients with CHB-related liver fibrosis were randomly assigned to treatment groups for receipt of a 12-month course of the antiviral drug entecavir alone (control group) or in combination with the TCM Liuweiwuling tablets. Patients were assessed before (pre-treatment) and after therapy and the treatment-related differences in clinical manifestations, levels of liver function markers and liver fibrosis indexes, color ultrasound images, and hepatitis B virus (HBV) DNA load were compared between the two groups by statistical analysis.

Objective: To study the inhibition of voltage-activated K(+) conductance and cell proliferation by 4-aminopyridine (4-AP) in the human small-cell lung cancer (SCLC).

Methods: Inhibition of voltage-activated K(+) current by 4-AP through the whole-cell patch-clamp technique in SCLC cell line was studied. The influence on the cell-cycle by 4-AP was observed by flow cytometry to identify the in vitro inhibition by 4-AP to the cell proliferation of the SCLC cell line.
