Objective To establish rat heart failure(HF)model following myocardial infarction(MI)and then detect the possible cytokines expression levels at different HF groups,so to explore the development of cytokines levels during the progression of heart failure.Methods The model was established by ligature of the left descending coronary artery.The rats were assessed by echocardiography and cardiac catheterization before and after 4 and 16 weeks following coronary ligature.Serum levels of TNF-α and IL-6 were determined.Results ①Serum cytokines could not be detectable in sham group using ELISA Methods,while in operated group,the concentration of TNF-α and IL-6 were significantly higher,especially IL-6.②The diagnosis coincidence between echocardiography and hemodynamics was high.Echocardiography can be used as an invasive measure to assess cardiac function in rat heart failure models.Conclusion ①Cytokines content is higher in compensated compared with the other two groups,especially to the IL-6 expression.②Cardiac ultrasound can be used as a useful method in monitoring postinfarction heart failure rat model,especially as an invasive measure.It can provide us successive data of the model.

Objective To observe the preventive and therapeutic effects of Sagittara Sagittifolia L. Xiao-Zhi Pills on nonalcoholic steatohepatitis (NASH) in rats. Methods Rat NASH models were established and the rats were divided randomly into five groups: the normal group, model group, high-dosage group and low-dosage groups of the treatment, and Dongbao Gantai positive drug group. Histopathological changes of the liver were observed. The levels of MDA, superoxide dismutase (SOD), and NO (nitric oxide) in the liver homogenate were determined. Expressions of cyclooxygenase-2 (cox-2) and inducible nitric oxide synthase (iNOS) in the liver were determined with immunohistochemical technique. Results In model group, extensive adipose degeneration and inflammatory cell infiltration were found in the liver. Compared with those in normal group, SOD activities in model group were obviously decreased (P<0.01), the contents of MDA and NO were obviously increased (P<0.01), and the expressions of cox-2 and iNOS proteins were obviously increased (P<0.01). Compared with those in model group, the activities of SOD in treatment groups were obviously increased (P<0.01), the contents of MDA and NO were obviously decreased (P<0.01), and the expressions of COX-2 and iNOS proteins were obviously decreased (P<0.01). The effect of high-dosage group was more obvious than that of Dongbao Gantai group (P<0.05). Conclusion Sagittara Sagittifolia L. Xiao-Zhi Pills can effectively prevent and treat nonalcoholic steatohepatitis in rats, and its mechanism may be associated with ameliorating hepatocellular steatosis, removing the free radicals and enhancing the anti-oxidation and anti-inflammation capability.

Objective To investigate the clinical characteristics and treatment efficacy in newly diagnosed multiple myeloma (MM). Methods The clinical data and treatment methods of 176 patients with newly diagnosed MM were retrospectively analyzed. Results The most common chief complaint in the patients with MM was bone pain. 26.1 % (46/176) patients once experienced misdiagnosis. The overall response rate (ORR) was 65.9 % (116/176), the ORR of bortezomib group (81.0 %, 34/42) was significantly higher than that of M2 regimen group (61.8 %, 34/55) and VAD regimen group (60.8 %, 48/79) (P<0.05). Between normal renal function subgroup and renal insufficiency subgroup in bortezomib group, the efficacy was no significant difference (P>0.05). The most common adverse reactions included hematologic toxicity, infection and peripheral neurotoxicity. Multiple organ failure was the main cause of death (47.1 %, 16/34). Conclusions The clinical manifestations of MM are complex and diverse, which is easy to be misdiagnosed. Molecular genetic abnormalities are closely related to prognosis. Proteasome inhibitor bortezomib can improve the curative effect and not be affected by renal function. To prolong the survival time of the patients needs to prevent and control the infection and renal insufficiency actively.

Objective:To observe dynamic change of phosphorylated tau protein and non phosphorylated tau protein in axon and explore whether GSK3 in serum were related with phosphorylated tau protein in brain of EAE mice.Methods: Mice were randomly divided into six groups:EAE group of acute stage,EAE group of paralytic stage,EAE group of remission stage,control group of acute stage,control group of paralytic stage,control group of remission stage,each group had twelve mice.EAE model were constructed by MOG35-55 peptides in EAE group, the saline was used in control group.The nerve function scores and incidence were observed and compared.We observed degree of brain inflammation by HE staining and measured axons which contained two kinds of tau protein by immunohistochemistry.GSK3 in serum was tested to find correlation with phosphorylated tau protein in brain by ELISA method.Results:Nerve function scores in EAE group were higher than control group.The degree of inflammation damage was more serious in EAE group than control group,gradually enhancing with time.Phosphorylated tau protein in brain gradually increased before mice paralyzing(P<0.01),but it decreased when symptom relieved(P<0.01).GSK3 in serum were correlated with phosphorylated tau protein in brain(r=0.9326,P<0.01),linear regression equation:Y=2.950+0.418X.Conclusion:Phosphorylated tau protein in brain are correlated with axon damage and GSK3 in serum could indirectly reflect axon damage in brain.

Long non-coding RNAs (lncRNAs) are non-coding RNAs that have transcript lengths exceeding 200 bp and do not have the capacity for protein coding because of having no open reading frame. In the human genome, lncRNAs play important regulato-ry roles in the process of epigenetic, transcription and post-transcription, so they have become the focus of research followed by mi-croRNAs. The abnormal expression of lncRNAs in cancer usually represents different functions, such as the function of oncogenes or tumor suppressor genes, which promote or inhibit tumor growth. Lung cancer is a common malignant tumor with a five-year survival rate of 17%. Previous literature shows that MALAT1, H19, lincRNA p21, UCA1, and BC200 are closely related to the development of lung cancer. They could promote cancer growth, invasion and metastasis, apoptosis and induce drug resistance, and so on. This review aims to provide assistance in the diagnosis, treatment, and prognosis of lung cancer by clarifying the functions and mechanisms of ln-cRNAs.
