Three-dimensional chromosome conformation capture and its derived technologies / 生物工程学报

Linear chromatin is compacted into eukaryotic nucleus through a complex and multi-layered architecture. Consequently, chromatin conformation in a local or long-distance manner is strongly correlated with gene expression. Chromosome conformation capture (3C) technology, together with its variants like 4C/5C/Hi-C, has been well developed to study chromatin looping and whole genome structure. In this review, we introduce new technologies including chromosome capture combined with immunoprecipitation, nuclei acid-based hybridization, single cell and genome sequencing, as well as their application.

Clinical study for mouse nerve growth factor on treating herpes zoster / 中国医师进修杂志

Objective To observe the effect of mouse nerve growth factor (mNGF) on treating herpes zoster.Methods The 64 patients with herpes zoster were divided into treatment group and control group by random digits table with 32 cases each.The control group received only routine treatment,the treatment group based on routine treatment combined with mNGF 30 μ g,both groups were treated 14 days.Pain changes of two groups were observed in once every 5 days,a total of 1 month.Results The times of pain to lessen and the pain to vanish of treatment group were (4.36 ± 2.01) and (12.29 ± 1.98) d,those of control group were (7.23 ±3.57) and (20.36 ±2.24) d,there were significant differences (t =5.21 and 8.37,P ＜0.01).The effective rate of treatment group was significantly higher than that of control group [96.9％(31/32) vs.71.9％(23/32),P＜0.05].Conclusion mNGF combined with routine treatment can significantly shorten the course of nerve injury and improve the prognosis with few adverse reactions.
