Venezuelan equine encephalitis (VEE) is a zoonotic disease caused by the Venezuelan equine encephalitis virus (VEEV) complex. This disease has not yet been reported in China, and it is therefore essential to establish a rapid and accurate method for detection of the virus in order to prevent and control this disease. In this study, a one-step real-time quantitative RT-PCR method was developed for the detection of the VEEV complex. A pair of specific primers and a Taqman probe were designed corresponding to a conserved region of the VEEV gene nspl, allowing the detection of all known strains of different sub- types of the virus. Using RNA synthesized by in vitro transcription as template, the sensitivity of this method was measured at 3.27 x 10(2) copies/microL. No signal was generated in response to RNA from Chikungunya virus (CHIKV), nor to RNA encoding the nsp1 fragment of Eastern equine encephalitis virus (EE-EV) or Western equine encephalitis virus (WEEV), all of which belong to the same genus as VEEV. This indicates that the method has excellent specificity. These results show that this one-step real-time quantitative RT-PCR method may provide an effective tool for the detection of VEEV in China.

Neurofibroma is an autosomal dominant genetic disease which is originated from the abnormal differentiation of neural crest cells and would cause system damage.NF can occur at most organs in the body,while it is rarely seen in the common bile duct.In February 2007,1 old patients with NF was admitted to the Lishui Central Hospital of Zhejiang Province.The results of preoperative magnetic resonance cholangiopancreatography (MRCP) revealed that the common bile duct was slightly dilated,and the diameter of the common bile duct was 1.2 cm.A nodular short T2 signal lesion was detected at the middle part of the common bile duct with the size of 1.4 cm × 1.6 cm.The results of intraoperative rapid frozen section pathological examination showed that the lesion was cholangiocarcinoma,then cholangiocarcinoma resection + biliojejunal Roux-en-Y anastomosis was applied to the patient.Postoperative pathological examination confirmed that the lesion was neurofibroma.The patient was followed up for 7 years and died of pulmonary infection in June 2014.The clinical presentation of neurofibroma of the common bile duct is untypical.Space-occupying lesions detected in the patients with history of bile duct injury or operation should be considered to be diagnosed as neurofibroma.Special attention should be paid to the accuracy of the results of rapid frozen section pathological examination in order to avoid missdiagnosis.

p70 ribosomal protein S6 kinase (p70S6K), an important member of AGC family, is a kind of multifunctional Ser/Thr kinases, which plays an important role in mTOR signaling cascade. The p70 ribosomal protein S6 kinase is closely associated with diverse cellular processes such as protein synthesis, mRNA processing, glucose homeostasis, cell growth and apoptosis. Recent studies have highlighted the important role of S6K in cancer, which arose interests of scientific researchers for the design and discovery of anti-cancer agents. Herein, the mechanisms of S6K and available inhibitors are reviewed.
