Cytotoxicity of 4 Wild Mushrooms in a Case of Yunnan Sudden Unexplained Death.

Objectives: To explore the cytotoxicity of four wild mushrooms involved in a case of Yunnan sudden unexplained death (YNSUD), to provide the experimental basis for prevention and treatment of YNSUD.

Methods: Four kinds of wild mushrooms that were eaten by family members in this YNSUD incident were collected and identified by expert identification and gene sequencing. Raw extracts from four wild mushrooms were extracted by ultrasonic extraction to intervene HEK293 cells, and the mushrooms with obvious cytotoxicity were screened by Cell Counting Kit-8 (CCK-8).

Functional analysis of HADH c.99C>G shows that the variant causes the proliferation of pancreatic islets and leu-sensitive hyperinsulinaemia.

A novel missense variant (NM_005327.7: c.99C>G, p.

Pneumonia, Multiple Pulmonary Infarction and Abscess Caused by a Bamboo Stick Accidentally Piercing into Chest: a Case Misdiagnosed as Pulmonary Tuberculosis.

Computed tomography (CT) examination is the major measure for detecting and diagnosis of foreign bodies in human body. Although CT has high sensitivity in diagnosis of foreign body, some interference factors may still lead to missed diagnosis or misdiagnosis. Here we report a rare case that a bamboo stick accidentally pierced into the left chest of a young man who was drunk and unware of this hurt.

Postmortem Analysis of 4 Mutation Hotspots of KCNQ1, KCNH2, and SCN5A Genes in Sudden Unexplained Death in Southwest of China.

Long QT syndrome (LQTS) is known to be involved in some sudden unexplained death (SUD) cases. To make clear whether the pathogenic genes of LQTS are involved in SUD in Yunnan province, southwest of China, we examined 4 mutation hotspot segments of KCNQ1, KCNH2, and SCN5A genes in 83 SUD cases using polymerase chain reaction and direct DNA sequencing. Genomic DNA was extracted from paraffin-embedded tissues in 83 cases of sudden cardiac death.

The comparison of methods to identify the presence of fibrocytes in formalin-fixed, paraffin-embedded archival cardiac tissue with coronary heart disease.

The purpose of this study was to find the optimal technical approach to identify the presence of fibrocytes in formalin-fixed, paraffin-embedded archival cardiac tissue with CHD (coronary heart disease). Using the coexpression markers CD45 and αSMA, the presence of fibrocytes was examined by three different methods, including double immunohistochemistry staining, combination labeling of immunohistochemistry and immunofluorescence and double immunofluorescence labeling. Double immunohistochemistry staining was very difficult to identify the CD45(+)/αSMA(+) fibrocytes.

Extracorporeal cardiac shock wave therapy ameliorates myocardial fibrosis by decreasing the amount of fibrocytes after acute myocardial infarction in pigs.

Objectives: Extracorporeal shock wave (SW) therapy ameliorates cardiac remodeling after acute myocardial infarction (AMI). However, it remains to be examined whether and how SW therapy ameliorates myocardial fibrosis after AMI. Fibrocytes are associated with myocardial fibrosis.

Fibrocytes are associated with the fibrosis of coronary heart disease.

Fibrocytes contribute significantly to fibrosis in many cardiac diseases. However, it is not clear whether fibrocytes are associated with the fibrosis in coronary heart disease (CHD). The aim of this study was to determine whether fibrocytes are involved in cardiac fibrosis in CHD.

Expression and hypermethylation of p27 kip1 in hepatocarcinogenesis.

Aim: To study the expressions of p27 kip1 protein and p27mRNA, the hypermethylation of p27 kip1 and the relation between them in various stages of hepatocarcinogenesis.

Methods: p27 protein and p27mRNA were detected by immunohistochemical staining and in situ hybridization respectively in 68 cases of normal liver, liver cirrhosis, pericancerous cirrhosis and hepatocellular carcinoma (HCC). The hypermethylation of p27 kip1 was detected by methylation-specific PCR (MSP) in 44 cases of normal liver, liver cirrhosis, and HCC.
