Colorectal cancer is one of the most common malignant diseases that threatens human being's health. With researches on microRNAs (miRNAs) getting deeper and wider, more evidences revealed that a great many of miRNAs have been involved in the development of colorectal cancer and have the potential to become the biomarker for early diagnosis, prediction of prognosis and recurrence of colorectal cancer. MiRNA-143/miRNA-145 are significantly reduced in several cancers, including colorectal cancer, showing an antitumorigenic activity. In the present article, we make a brief review on the advances in the researches on miRNA-143/miRNA-145 and colorectal cancer to provide guidance for further explorations of the mechanism and target therapy of this disease.
This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM),which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal,etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i.e. transparent organic glass external layer,which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual,facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.
ObjectiveTo evaluate the effectiveness of mass vaccination campaign of hepatitis A vaccine (Hep A) and Measles-Mumps-Rubella live attenuated vaccine (MMR) vaccine in children in stricken regions of 4.20 Lushan earthquake in Sichuan province. MethodsAs the requirements of Sichuan Provincial Health Bureau, the mass campaign was implemented in Lushan county, Baoxing county and the victim settlement localities of other 6 counties during May 6th to 12th, 2013. Hep A and MMR were vaccinated, which targeted children aged from 18 months to 14 years and children aged from 8 months to 14 years, respectively. The vaccination rates were evaluated through reports and on-site rapid review of earthquake regions. ResultsAs of May 16th, 2013, 38 988 doses of Hepatitis A vaccine and 38 696 doses of MMR vaccine were vaccinated in 8 counties of Ya'an. Based on reports, the vaccination rates of Hep A and MMR vaccine of Ya'an were 99.01% and 98.87%, respectively. Based on reviews, vaccination rates of Hep A and MMR vaccine of Lushan and Baoxing were 97.40% and 97.06%, respectively. ConclusionMass vaccination campaign of Hep A and MMR in children in stricken regions of 4.20 Lushan earthquake in Sichuan province yields expected results. The mass campaign is wellorganized and implemented effectively, and the coverage matches the requirements. Timely decision, assistance from associated prefectures and the establishment of Childhood Immunization Information System play an important role in the campaign.
