With the development of computer techniques and medical imaging examining methods , precise radiotherapy is becoming the major direction of radiotherapy for tuomors. Both of tumor control probability and normal tissue complication probability are improved with precise radiotherapy. This paper critically review the value of PET-CT and breathing control in precise radiotherapy for non-small-cell lung cancer (NSCLC).

Japanese encephalitis virus (JEV) is a pathogenic mosquito-borne flavivirus which is responsible for outbreaks of severe viral encephalitis. The cellular entry of JEV is a prerequisite for Japanese encephalitis, so the understanding of its underlying mechanisms will provide more approaches for treating such disease. In recent years, increasing research has been conducted to investigate the mechanisms of cellular entry of JEV, and the results of research on other flavivirus have expanded the research directions for JEV. More methods will be used to suppress JEV infection because of the development of E protein antibodies and the discovery of several inhibitors of the cellular entry process. This review will summarize the recent advances in the mechanisms of JEV cellular entry and membrane fusion.

Retinal ganglion cells are crucial in the formation of vision. Injury or death of retinal ganglion cells may lead to irreversibly damage of visual function. Glaucoma, diabetic retinopathy, hypertension, and other blind leading diseases can cause the damage or progressively apoptosis of retinal ganglion cells. Currently, there is no specific treatment to restore vision damage caused by those diseases. Scholars at home and abroad focus on stem cells transplantation in order to recover the visual function of patients. Two categories are mainly involved in stem cell transplantation, one is the replacement therapy based on stem cells, the other is to promote the secretion of some factors to protect ganglion cells through stem cell transplantation. In this review, we aim to summarize the potential of stems cell transplantation to treat retinal ganglion cells related diseases, and discuss the differentiation of different types of stem cells to retinal ganglion cells.

"CapFinder" technology,which can be used to clone the full length of 5′ UTR sequence of mRNA,was described.This technology used the terminal transferase activity of certain MMLV RT variants that added 3-5 residues(predominantly dC) to the 3′end of the first-strand cDNA exhibited when MMLV RT reached the 5′cap structure of mRNA.In the reverse reaction system containing GGG oligo,the terminal transferase activity was harnessed by the GGG oligo whose terminal stretch of dG residues can anneal to the dC-rich cDNA tail and serve as an extended template for RT.After RT switch templates from the mRNA template to the GGG oligo,a complete cDNA copy of the original RNA was synthesized with the additional GGG oligo sequences at the end.5′UTR of mRNA can be amplified with GGG oligo as forward primer and a gene-specific reverse primer.5′UTR of Bt toxin receptor E-Cadherin gene in midgut of cotton bollworm was cloned.

Acute myeloid leukemia (AML) is a genetic heterogeneous disease in which primordial and juvenile myeloid cells proliferate or accumulate abnormally in bone marrow, peripheral blood and other tissues, resulting in damage to normal hematopoietic function. Studies have shown that about 30% of AML patients have FMS-like tyrosine kinase 3 (FLT3), FLT3 abnormal regulation is closely related to the occurrence and development of AML. At present, FLT3 has become an important target for developing small molecular targeted drugs. Currently, a variety of FLT3 inhibitors and FLT3 degraders have been developed targeting FLT3, and some compounds have exhibited good anti-AML activity. This article summarizes and sorts out the current mainstream drugs for AML therapeutic targeting FLT3, in order to provide a reference for the development and design of AML drugs.

Objective To investigate immunophenotypic characteristics of uterine natural killer (uNK)cells and helper T cell 1/helper T cell 2(Th1/Th2)immunity in third trimester decidua in preeclampsia.Methods The proportions of uNK cell subsets,expression of CD_(69)and CD_(94)on uNK cells and Th1/Th2 immunity in decidua were determined in 20 cases of preeclampsia patients and 11 cases of normal term pregnancies by flow cytometric analysis.Results The percentage of CD_(56)~(bright)CD_(16)~-uNK cell subset in preeclampsia patients and the controls was(17.3?11.1)% vs(17.9?16.8)%,that of CD_(56)~(dim) CD_(16)~+uNK cell subset was(16.3?8.7)% vs(16.2?8.8)%;that of CD_(56)~+CD_(69)~+uNK cells was(37.9 ?18.9)% vs(36.8?19.7)%,that of CD_(56)~+CD_(94)~+uNK cells was(34.9?15.2)% vs(32.7?16.2)% and the ratio of CD_(56)~+CD_(69)~+/CD_(56)~+CD_(94)~+was 1.1?0.2,1.2?0.6.No statistical difference was shown in the above values between the preeclampsia patients and controls.The percentage of cytoto xic T cell(Tc)2 cells was significantly lower in the decidua of preeclampsia patients [(3.0?1.0)% vs(4.3?0.9)%,P= 0.001 ],and the ratio of Tc1/Tc2 in preeclampsia patients was significantly higher than that of normal term pregnancies(17.8?3.4 vs 11.8?4.6;P=0.001);the ratio of Th1/Th2 was increased(15.1?2.4 vs 13.2?3.1;P=0.06).Conclusions The immunophenotypie characteristics of uNK cells do not present any significant change in preeclampsia patients.Owing to Tc2 cell decrease,the Th1/Th2 immunity shifts to Th1 type immunity in the decidua,which might contribute to the pathogenesis of preeclampsia.
