MicroRNAs(miRNAs) are endogenous non-coding RNAs,about 20 nucleotides in length.They play a pivotal role in the regulation of genes involved in diverse biology processes such as cell development,proliferation,differentiation and apoptosis by the translation repression or mRNA degradation.Recent evidence has suggested that miRNA alterations are involved in the initiation and progression of various human cancer including hepatocellular carcinoma(HCC),and miRNA-expression profiling of HCC has identified signatures associated with diagnosis,staging,progression and prognosis.As a novel molecular target,miRNAs holds great promise in diagnosis and biotherapy of HCC.

Circulating nucleic acids (CNAs) are extracellular nucleic acids found in cell-free serum,plasma and other body fluids from healthy subjects as well as in patients. The ability to detect and quantitate specific DNA and RNA sequences has opened up the possibility of diagnosis and monitoring of diseases,especially in the field of cancer. Furthermore,in some recent studies it has been suggested a kind of non-coding RNA-microRNA (miRNA),also exist in cell-free serum and plasma,highlighting the field of using CNAs to diagnose cancer. As a novel tumor marker,tumor-specific circulating miRNAs holds great promise in early diagnosis of cancer.

Hepatocellular carcinoma(HCC),one of the most common malignant tumors,is the main cause of cancer death in China.Early diagnosis of the disease is of great importance.Serum tumor markers have been effective for detecting HCC for a long time.Among those markers,alpha fetoprotein(AFP)is the most widely used one in detecting patients with HCC,but it has limited utility for detecting HCC due to its limited sensitivity and specificity.Searching better markers for HCC has been a re- search focus in recent years.This review introduces many useful markers to supplement AFP for detecting HCC.

Objective To compare the safety of recombinant human tumor necrosis factor-Fc (rhTNFR:Fc) and other DMARDs,in patients with rheumatoid arthritis (RA),ankylosing spondylitis (AS),juvenile idiopathetic arthritis (JIA) or psoriatic arthritis (PsA).Methods Patients who received rhTNFR:Fc 25 mg twice weekly from May 2006 to March 2009 were involved in this open-lable study.Safety assessments were carried out at regular intervals.Results Of the 2014 patients enrolled in the open-label trial,1388,421 and 232 were RA,AS or other diseases,such as JIA and P.sA respectively.Frequent adverse events included injection-site reactions (2.67％),rash (1.87％) and hyperamino transferase (1.80％) in RA patients.Similarly,injection-site reactions (5.23％),hyperaminotransferase (2.38％) and rash (0.71％) were frequent in AS patients.Upper respiratory infection was most frequent among infectious adverse events.There were no reports of patients with serious adverse events,dead case,TB infection and malignancies.Conclusion rhTNFR:Fc has shown a favourable safety profile in Chinese rheumatic disease patients.

The types of synapses and some morphological features of the synaptic submicroscopic structures of rat hypothalamic ventromedial nucleus (HVM) have been described in this study. A total of 1 005 synapses is observed. The percentage of axo-dendritic synapse is 96.6%. It covers the majority of the total number of synapses. The percentage of axo-somatic synapse is 2.8% and axo-axonic synapse is 0.5% of the total number of the synapses. The crest synapse which is never reported in the HVM was found to be 0.1%. Its postsynaptic elements come from clubbed finger-like dendritic crest which is characterized by prominent postsynaptic membrane thickening and subsynaptic dense bodies. Two presynaptic terminals contact the wall of the crest process side by side and contain spheric vesicles. In the axo-dendritic and axo-somatic synapses, the parallel synapse (including synaptic complex), the tangent-like synapse and serial-like synapse have been observed.

Objective To study the effect of Shenfu injection combined with low dose glucocorticoid on endothelial function and blood coagulation in elderly patients with severe pneumonia. Methods 120 patients with severe pneumonia in our hospital from January 2014 to January 2017 were selected,and randomly divided into treatment group and control group,60 cases in each groups.. All patients were treated with conventional treatment. On this basis, the control group was treated with small dose of glucocorticoid. The treatment group was treated with Shenfu Injection on the basis of the control group. The severity, endothelial function and coagulation function of the two groups were compared at different times after treatment. Results The scores of APACHE and 120 h in the two groups were significantly lower than those in the control group (P<0.05). The score of the treatment group was lower (P<0.05) than that of the control group (96 h). After treatment, the two groups of patients with s E-selectin, V WF, APTT, D-D were significantly decreased, PLT significantly increased, significant difference (P<0.05); compared with the control group, s E-selectin, V WF, APTT, D-D and other indicators of the treatment group decreased and PLT increased even more sharply, there is statistical significance (P<0.05). Conclusion Shenfu injection combined with small dose of glucocorticoid therapy, can alleviate the function and coagulation function in patients with endothelial damage, relieve endothelial dysfunction, improve coagulation status of patients, and has higher application value.

Objective To study the lymphocytes subsets including Th1 and Th2 cells in PBMC of children with bronchiolitis in acute period.Methods The present study enrolled 34 patients with bronchiolitis,23 of them were respiratory syncytial virus(RSV)and 11 non-RSV,and 22 age-matched normal infants.Fresh peripheral blood samples were treated and run through the flow cytometry.The percentage of lymphocytes subsets were acquired using simultest IMK-lymphcyte software.Results The results showed the percentage of CD3+ and CD4+ cells in bronchiolitis group was higher than that in control group(P
