[Effect of Gegen Qinlian Decoction on methylation and expression of Scd1gene in adipose tissue of insulin resistant rats and correlations between methylation and physiological and biochemical parameters].

This study aimed to explore the effect of Gegen Qinlian Decoction(GQD) on the methylation and mRNA expression level of stearoyl CoA desaturase(SCD) gene in the adipose tissue of rats with insulin resistance(IR) induced by high-fat diet as well as the correlations between methylation and physiological and biochemical indicators. The animals were divided into seven groups, namely, blank control(C) group, IR model group, low-(1.65 g·kg~(-1)), medium-(4.

CAF-derived midkine promotes EMT and cisplatin resistance by upregulating lncRNA ST7-AS1 in gastric cancer.

This study aimed to investigate the role of cancer-associated fibroblast (CAF)-derived midkine (MK) in cisplatin (DDP) resistance. The primary cultures of CAFs and non-cancer fibroblasts (NFs) were isolated and purified. The DDP-resistant gastric cancer (GC) cells were cultured with CAF-conditioned medium.

CircN4BP2L2 promotes colorectal cancer growth and metastasis through regulation of the miR-340-5p/CXCR4 axis.

Colorectal cancer (CRC) is the third leading cause of cancer-related death worldwide. Dysregulation of circular RNAs (circRNAs) appears to be a critical factor in CRC progression. However, mechanistic studies delineating the role of circRNAs in CRC remain limited.

[Preliminary study on effect of Gegen Qinlian Decoction on enzyme activity, gene expression and methylation level of FASN in adipose tissue of rats with insulin resistance].

To investigate the effect of Gegen Qinlian Decoction(GQD) on enzyme activity, gene expression and methylation level of fatty acid synthase(FASN) in adipose tissue from rats with insulin resistance induced by high-fat diet. The 60% fat-powered high-fat diet was continuously given to male SD rats to induce the insulin resistance model. Then, they were divided into five groups randomly and administrated by gavage every day for 16 weeks with following drugs respectively: 10 mL·kg~(-1)water for control group(C) and insulin resistance model control group(IR), 1.

[Distribution of ejaculatory duct openings and the method of entering the vesiculoscope into the seminal vesicle].

Objective: To search for an optimal method of entering the seminal vesiculoscope based on the distribution of ejaculatory duct openings.

Methods: Fifty-six patients with refractory hemospermia underwent seminal vesiculoscopy in our hospital from July 2014 to December 2016. We observed the positions of the ejaculatory duct openings under the seminal vesiculoscope, analyzed their distribution, and explored the optimal methods of entering the seminal vesiculoscope according to the success rate of operation, experience of the operators, video data and operation records.

Integrated Metabolomics and Morphogenesis Reveal Volatile Signaling of the Nematode-Trapping Fungus Arthrobotrys oligospora.

The adjustment of metabolic patterns is fundamental to fungal biology and plays vital roles in adaptation to diverse ecological challenges. Nematode-trapping fungi can switch their lifestyle from saprophytic to pathogenic by developing specific trapping devices induced by nematodes to infect their prey as a response to nutrient depletion in nature. However, the chemical identity of the specific fungal metabolites used during the switch remains poorly understood.

Nematicidal Key Precursors for the Biosynthesis of Morphological Regulatory Arthrosporols in the Nematode-Trapping Fungus Arthrobotrys oligospora.

Arthrobotrys oligospora is the first recognized nematode-trapping fungus and by far the most abundant in the environment. Our recent study revealed the polyketide synthase (PKS) gene AOL_s00215g283 in A. oligospora involved in the production of many secondary metabolites and the trap formation of the fungus.

High Trap Formation and Low Metabolite Production by Disruption of the Polyketide Synthase Gene Involved in the Biosynthesis of Arthrosporols from Nematode-Trapping Fungus Arthrobotrys oligospora.

A group of morphology regulatory arthrosporol metabolites have been recently characterized from carnivorous fungus Arthrobotrys oligospora that can develop trapping networks to capture their prey. A combination of genetic manipulation and chemical analyses was applied to characterize the function of one polyketide synthase (PKS) gene AOL_s00215g283 in A. oligospora, which was putatively involved in the production of 6-methylsalicylic acid.

Mesohepatectomy for centrally located large hepatocellular carcinoma: Indications, techniques, and outcomes.

Background: Whether mesohepatectomy should be performed for large hepatocellular carcinoma (HCC) located in the central part of the liver is controversial, and the safety and long-term survival after this operation remain to be investigated.

Methods: Between January 2002 and December 2012, 696 patients with HCC located in the central part of the liver who received liver resection in our hospital were included in this study. These patients were divided into three groups: 158 patients with large HCC (tumor size >5.

Solitary large hepatocellular carcinoma: a specific subtype of hepatocellular carcinoma with good outcome after hepatic resection.

Objective: To evaluate and compare the clinical and pathologic characteristics and outcomes after hepatic resection of large hepatocellular carcinoma (SLHCC), small HCC (SHCC), and nodular HCC (NHCC).

Summary Background Data: Traditional viewpoint insists that the classification and prognosis of HCC are determined by the size of HCC. As a result, large HCC is often considered as advanced and unresectable.

Expressions of cysteine-rich61, connective tissue growth factor and Nov genes in hepatocellular carcinoma and their clinical significance.

Aim: To investigate the expression of cysteine-rich61 (Cyr61), connective tissue growth factor (CTGF) and nephroblastoma overexpressed gene (Nov) in hepatocellular carcinoma (HCC), and to evaluate the relationship between Cyr61, CTGF and Nov genes expression with invasion and metastasis of HCC.

Methods: Thirty-one HCC specimens were divided into small hepatocellular carcinoma (SHCC), nodular hepatocellular carcinoma (NHCC), solitary large hepatocellular carcinoma (SLHCC) according to their diameter and number of nodes. Reverse transcription polymerse chain reaction (RT-PCR) was used to detect the mRNA expression levels of Cyr61, CTGF and Nov genes in 31 resected specimens of hepatocellular carcinoma and para-cancerous normal liver tissues semi-quantitatively and the relation between their expression levels and clinical pathological parameters were compared.
