Respiratory distress syndrome( RDS) is a critical respiratory disease and commonly occurs in preterm infants. Preterm RDS is mainly due to the deficiency of lung surfactant. However,recent studies have in-dicated that genetic susceptibility may involve in the pathogenesis of RDS in preterm infants. In this paper,recent research progresses of genetic susceptibility and related candidate genes of RDS in preterm infants at home and abroad are reviewed.

Objective To analyze the effect of modified Tongyou decoction combined with FOLFOX4 chemotherapy on pre-thrombus state and curative effect of patients with advanced prostatic cancer.Methods 142 patients with advanced prostatic cancer were collected,all patients were randomly divided into study group and control group,71 cases in each group.The control group was given FOLFOX4 chemotherapy and the study group was given modified Tongyou decoction on the baseis of the control group.After treatment,the serum levels of homocysteine(Hcy),D-two dimer(D-D),fibrinogen(FIB),the level of hemorrheology,clinical effect,the incidence of venous thrombosis in one years,the six month survival rate,the one year survival rate were detected in all patients.Resutls After treatment,compared with control group,the serum levels of Hcy,D-D,FIB,the whole blood high,middle and low-shear viscosities,plasma viscosity and the incidence of venous thrombosis in one years were higher in the study group and the difference was statistically significant(P<0.05);the erythrocyte deformability index,effective rate and one year survival rate were higher were higher in the study group and the difference was statistically significant(P<0.05).Conclusion The modified Tongyou decoction combined with FOLFOX4 chemotherapy in treatment of patients with advanced prostatic cancer can improve the prethrombotic state,improve the therapeutic effect,reduce the incidence of venous thrombosis and increase the one year survival rate,and have a guiding significance for clinic.

It has been reported that the high expression of gastrins and their receptors promotes some colorectal neoplasms cells proliferation and inhibit apoptosis.MicroRNAs (miRNAs) are closely related to gene expression regulation in colorectal neoplasms.Researches show that miRNAs have multiple intersections in the regulatory network of colorectal neoplasms with the signal transduction pathway of gatrins which controls the proliferation of colorectal neoplasms.Gastrins perhaps control the proliferation of colorectal neoplasms cells through miRNA signal transduction pathways.These findings have greatly expanded the understanding of the pathoge nesis of colorectal neoplasms and will provide new ideas and methods for the diagnosis and treatment of colorectal neoplasms.

Backgroud EDTA is an important calcium chelator,commonly used as an ophthalmic additive,its role in promoting corneal penetration of drug may facilitate transepithelial corneal collagen crosslinking.However,there were few reports about the penetration of riboflavin to corneal stroma enhanced by EDTA both home and abroad.Objective To determine the concentrations of riboflavin in corneal intrastromal under different interventions using high-performance liquid chromatography (HPLC).To ensure the efficacy and safety of 0.5％ EDTA in riboflavin penetrating to corneal stroma by the transepithelial procedures.Methods Fifteen New Zealand white rabbits were randomized into three groups,corneal epithelium of 5 rabbits were debrided,corneal epithelium of another 5 rabbits were left in situ and 0.5％ EDTA-Na2 was topically applied for 1 hour,and the corneal epithelium of last 5 rabbits were just left in situ,after those procedures 0.1％ riboflavin + 20％ dextran was applied topically to the corneas for 30 minutes(1 drop every 3 minutes).Then,the epithelium in the corneas of EDTA and epi-situ group were carefully removed before all the corneas were punched with an 8.5 mm diameter blade and homogenized subsequently.Ultimately,the riboflavin concentrations were determined by HPLC.Results After treated with riboflavin for 30minutes,the mean concentration of riboflavin in the epi-removed group was (23.54± 1.61)μg/g tissue,the EDTA group was (2.04 ±0.25)μg/g tissue and the epi-situ group was (1.44 ±0.06)μg/g tissue,showing significant difference among them (F =1792.839,P =0.000).There were statistically significant differences between any two groups (t =41.780,7.484,43.408,all at P ＜ 0.05).However,the riboflavin concentration of other two groups were failed to meet the theoretical value 15 μg/g tissue,excepted for epi-removed group.Conclusions The diffusion of riboflavin to the corneal stroma can be fully enhanced by removing the epithelium preoperatively,penetration enhancer EDTA can effectively promote the penetration of riboflavin to the cornea,but it still can not replace the role of removing epithelium on the penetration of riboflavin to the cornea.

Radiotherapy is the primary treatment for nasopharyngeal carcinoma, and the disease control rate and survival time are able to be greatly improved by enhancing the radiosensitivity. Via mechanisms such as binding to target genes mRNA 3'untranslated region (3'UTR), microRNA (miRNA) inhibits translation, which therefore regulates transcription of target genes and thus affect target protein expression. Recent research showed that miRNAs play significant roles in improvement of radiosensitivity in nasopharyngeal carcinoma. This article reviews mechanism of miRNA action to strengthen radiosensitivity of nasopharyngeal carcinoma and the future of clinical practice of miRNA in this disease.
