MicroRNAs(miRNAs) is a class of small endogenous noncoding RNAs with 22 nucleotides.They can negatively regulate gene expression by inhibiting target mRNAs′translation or degrading mRNAs .Up to now, it has been proved that miRNAs play an important role in cellular proliferation , apoptosis , cell differentiation , and embryonic development .In this article , mechanism and function of miRNAs , principal methodologies in the research of miRNAs and the latest development of miRNAs in early embryonic de -velopment are discussed .

Recent related researches pointed out that a series of adverse reactions may occur when homocysteine (Hcy) level exceeded normal range .More and more studies indicated that Hcy level abnormal elevating was an inde‐pendent risk factor for cardiovascular diseases .This article summarized its related research situation .

The function and contents of WeChat public account service in military hospitals were found out by in-vestigating the WeChat public account, which showed that WeChat public account service is provided in more and more military hospitals, but its function should be further expanded and its management should be strengthened.

Objective To discuss the application of DWI and DTI in diagnosis and evaluation of brain tumor. Methods Combining with literatures, the application of DWI and DTI in brain tumor diagnosis, differential diagnosis, tumors classi- fication, preoperative evaluation, operation plan establishment, follow-up role of treatment were reviewed and evaluated. Results The DWI and DTI were available to brain tumor diagnosis, differential diagnosis and tumor grade. The DTI could be clearly shown the influence of tumor with white matter quality, it was important in operation plan establishment. The combination of intra-operative MRI, functional MRI and DTI was valuable for brain tumor resection. In the meantime, the treatment response of tumor and the changes of treatment-induced white matter were accurately assessed by DTI. Conclu- sion With the MRI hardware and software technology development, the DWI and DTI imaging information can be provided important value in brain tumor pathological changes diagnosis, evaluation, therapeutic planning and post treatment assess- ment.

Objective To investigate the expression of α-smooth muscle actin (α-SMA)in patients with valvular atrial fibrillation and study the relationship betweenα-SMA and atrial fibrosis in patients with valvular atrial fibrillation (AF).Methods For this study we enrolled 84 consecutive patients with rheumatic heart disease who were to receive cardiac surgery.The patients were divided into AF group (AF,n=39)and sinus rhythm group (SR, n=45).Their clinical data including baseline demographics,routine laboratory test and echocardiographics were collected before surgery.The right atrial tissue (0 .3-0 .5 cm3 )was disserted during the surgery.Right atrial fibrosis was observed by Masson staining.The mRNA expression ofα-SMA in atrial tissue were determined by Real-time quantitative PCR.Western blot was used to measure the protein expression ofα-SMA in atrial tissue.Results The two groups did not significantly differ in sex ratio,age,blood pressure,blood biochemical indicators or other aspects of medical history (P>0.05).However,left and right atrium diameters in AF group were significantly larger than those in SR group (P<0 .05 ).Masson staining suggested that collagen volume fraction and collagen content were significantly higher in AF group than in SR group (P<0 .05 ).The mRNA and protein expressions ofα-SMA in right atrial tissue were obviously higher in AF group than in SR group (coefficients P<0 .05 ).The mRNA and protein expressions ofα-SMA from right atrial tissue in the 84 patients were positively correlated with collagen content (coefficients of 0.587 and 0.607;P=0.029,0.014,respectively).Conclusion There is significant atrial fibrosis in patients with valvular atrial fibrillation,which is closely related to up-regulated expression ofα-SMA gene.

Objective To observe the CT and MR features of hepatic hydatid cyst, and to evaluate the diagnostic value of CT and MR. Methods CT and MR images were retrospectively analyzed in 42 patients with pathologically proved hepatic hydatid diseases, and the relative articles were reviewed. Results Hepatic echinococcosis granulosus occured in 85.71% patients, among which ring like pattern calcification, the ribbon calcification, multiple daughter vesicles and detached membranes within cyst were the main findings. Hepatic echinococcosis alveolaris occured in 14.29% patients, whereas the main finding included calcification, small vacuoles, peninsula sign, geographic sign and colliquative necrosis. For the diagnosis of hepatic hydatidosis, MR was better than CT in the judgement of the cyst wall, detached membranes and fibrous septum, but was inferior to CT in displaying calcification sign. Conclusion Hepatic hydatidosis can be diagnosed either with CT or MR, CT is superior to MR in integrated diagnosis of this disease.

Objective To access the diagnostic value of volume helical shuttle (VHS)technology of spectrum CT in detection of the pulmonary arteriovenous malformations (PAVM).Methods Thirteen patients with PAVM confirmed by surgery and clinical data underwent CT pulmonary artery angiography with VHS technology,which were regarded as group A.The consecutive images at four different phases were gotten Meanwhile,other thirty patients underwent conventional CT pulmonary artery angiography using bolus tracking scan,regarded as Group B.The enhancement degrees of the pulmonary trunk were measured,and the image quality was also subjectively assessed by two radiologists separately,which were compared between two groups.Results In group A,the proportion of optimal phase in each of the four phases was 15.38% (2/13),46.15% (6/13),30.77% (4/13)and 7.7% (1/13),respectively.The mean CT value in pulmonary trunk was (329.21±41.63)HU in group A and (281.74±49.83)HU in group B,exhibiting no difference (P =0.989). The percentage of enhancement degree of pulmonary trunk more than 300 HU in group A was more than that in group B (P=0.000).However, the image quality of the main pulmonary artery,lobar pulmonary artery or segmental pulmonary artery was not significantly different between two groups (P >0.05).There were no statistically differences in mean DLP between group A of (715.54±195.37)mGy/cm and group B of (558.36±186.81)mGy/cm (t=3.737,P=0.068).Conclusion Spectrum CT VHS with higher image quality and enhancement degree is superior to conventional CT scan,which can be used to reduce the influence of individual circulation difference on image quality.
