Objective To observe and investigate b-type natriuretic peptide(BNP)levels in patients with hemorrhagic fever of seriously renal syndromes line of continuous renal replacement therapy(CRRT)application value.Methods From January 2015 to October 2015 were 48 cases of patients with hemorrhagic fever of seriously renal syndromes as the research object.Conservative treatment after 3 d better person to be included in the control group(24cases), no better continue CRRT(CRRT group, 24cases).Records in the two groups before the conservative treatment in patients with mean arterial pressure(MAP), albumin(propagated), hemoglobin(Hb), b-type natriuretic peptide(BNP)and a 24 h urine(24 h urine);Record after conservative treatment 3 d urea nitrogen, serum creatinine, BNP and 24 h urine(24 h urine).Compare the differences between the two groups of the clinical indicators.Results The control group with CRRT group propagated, urea nitrogen, serum creatinine, BNP-I, BNP-Ⅱ, 24 h urine-Ⅰ, 24 h urine-Ⅱ comparison, the difference had statistical significance (P<0.05).Conclusion The short term the 24 h urine after conservative treatment and BNP levels can better predict whether patients with hemorrhagic fever of Seriously renal syndromes should be line of CRRT.

Objective To investigate the expression and effect of zinc-finger protein kuppel-like factor4(KLF4) in leukemic cell line K562. Methods The lever of mRNA and protein of KLF4 is determined with real-time PCR and Western blot in human peripheral monoeyte/macrophage and K562 cells. Results Compared with control group (0.43±0.03), the expression of KLF4 mRNA in K562 cells (0.02±0.01) wassignificant different(P＜0,05). The expression of KLF4 protein in human peripheral monocyte macrophage is higher than that in K562 cells. Conclusion The low expression of KLF4 was present in leukemic cell line K562,which may suggest that KLF4 gene maybe a tumor inhibitor factor, and partially involved in leukemogenesis.

Objective To study the effects of sesamin on lipid metabolism disorders in hyperlipidemia rats. Methods The hyperlipidemia SD rat models were established with high-fat diet. These rats had been interfered by sesamin for seven weeks, and then had their levels of serum lipids, antioxidant enzymes and peroxidation products determined. The morphological changes in their livers were observed. Results Sesamin could reduce the hyperlipidemia rats' serum total cholesterol, triglyceride, low-density lipoprotein cholesterol and apolipoprotein B levels, and properly increase high-density lipoprotein cholesterol and apolipoprotein A contents (P<0.05). It also reduced the rats' free radical metabolites in serum MDA contents, raised the activities of superoxide dismutase and glutathione peroxidase, and enhanced the body's capacity of inhibiting hydroxyl free radicals (P<0.05). Sesamin of high, medium and low dosage had different effects in relieving liver steatosis of the hyperlipidemia rats. Conclusion Sesamin can regulate lipid metabolism of hyperlipidemia rats, alleviate oxidative stress of the body, and improve liver steatosis.

Objective To study the effect of sesamin on glucose metabolism in hyperlipidemia rats. Method The hyperlipidemia SD rats were established by high lipid diet. These rats were intervened by sesamin for 7 w,and then their serum lipids were determined. Fasting blood glucose (FBS),glycosylated hemoglobin (HbA1c),insulin,and the pathological changes of pancreas were observed. Results Sesamin could reduce serum TC,TG,LDL-C,apoB and insulin levels,appropriately increase HDL-C and apoA contents (P

Mitochondrial adenosine triphosphate (ATP) synthase is the key enzyme of mitochondrial oxidative phosphorylation reaction. The down-regulation of the mitochondrial ATP synthase is a hallmark of most human carcinomas, which is the embodiment of the bioenergetic signature of cancer in the performance of the decreased oxidative phosphorylation and increased aerobic glycolysis. Combining with the bioenergetic signature of cancer, studies showed that mitochondrial ATP synthase and multidrug resistance and adverse prognosis of tumor were closely related. Its mechanisms are related to post-transcriptional regulation of the ATP synthase, the hypermethylation of the ATP synthase gene and the inhibitor peptide of the mitochondrial ATP synthase, called ATP synthase inhibitory factor 1 (IF1). In this review, we stress the biological characteristics of mitochondrial ATP synthase and the relationship between ATP synthase and multidrug resistance and prognosis of Malignant tumor, in order to find a new way for tumor therapy.

Objective To develop and identify the monoclonal antibodies (McAbs) against Region II~+ motif in circumsporozoite protein of Plasmodium falciparum. Methods BALB/c mice were immunized with 12 peptides within Region Ⅱ~+ in circumsporozoite protein of P. falciparum. Spleen cells isolated from the immunized mice were fused with myeloma cell. After three times screening with ELISA, 3 positive hybridoma cell lines were obtained. Results ELISA test indicated that the McAbs reacted with recombinant circumsporozoite protein fragment containing tandemly repeat region and conserved Region II~+. IFA test showed that the McAbs recognized not only the sporozoites of P. falciparum, but also the sporozoifes of P. yoelii. Conclusion McAbs obtained can probe the Region II~+ motif in circumsporozoite protein of P. falciparum, which might also recognize that of other Plasmodium species.

Objective To observe the anti-tumor effect of ethaselen on transplanted liver cancer(H22)and Lewis lung cancer mice.Methods The transplanted liver cancer(H22)and Lewis lung cancer mice models were established.Each genus consisted of 60 mice,which were divided into control,CTX,and three ethaselen dose groups,respectively,with 12 mice in each.Intraperitoneal injection(ip.)of three dosages was performed once a day through the abdominal wall separately,from the second to the eighth day after cancer was transplanted.On the eleventh day,six mice in each group were killed to calculate the tumor inhibition ratio and observe the cell cycle by flow cytometry,and the others were observed for the life extension ratio.Results When ethaselen was given at the dosage of 25,12.5 and 6.3 mg/kg,the tumor inhibition ratio was 52.5%,43.6% and 30.2%,and the life extension ratio was 56.6%,38.7% and 14.2% in the transplanted liver cancer(H22)mice,respectively.The tumor inhibition ratio was 43.8%,29.6% and 18.9%,and the life extension ratio was 47.3%,17.9% and 6.3% in the transplanted Lewis lung cancer mice,respectively.Compared with that of the control,the apoptosis ratio was obviously increased in each group,and there was obviously induced S phase arrest in 25.0 mg/kg(P

Objective To explore the effect of Ulinastatin on proinflammatory cytokines of patients undergoing operation of intracranial aneurysm embolization. Methods 40 patients undergoing operation of intracranial aneurysm embolization were randomly divided into 2 groups (n = 20): ulinastatin group (Group U), normal saline group (Group C). In group U, 6 000 IU/kg Ulinastatin was infused via vein before anesthesia induction, the group C received the injection of isovolume normal saline. Exsanguinated arterial blood at T1, T2, T3, T4 and T5 five time points were taken to measure TNF-α and IL-6 in serum. Results The contents of TNF-α and IL-6 in serum both increased at T3, T4 and T5 compared to that at T1 in both groups; both TNF-α and IL-6 significantly decreased in Group U compared to that in Group C at the same time point. Conclusion Ulinastatin may inhibit the release of inflammatory mediators and lighten cerebral ischemia-reperfusion injury in patients undergoing operation of intracranial aneurysm embolization.

Objective To study the inhibitory effect of hammerhead ribozyme targeting connective tissue growth factor(CTGF) on collagen I synthesis and cell cycle progression of human hepatic stellate cell line(LX-2) cells.Methods Hammerhead ribozyme cDNA targeting CTGF mRNA plus two self-cleaving sequences were inserted into pTriEx2 vector to construct a recombinant vector pTriCTGF-Rz.LX-2 cells were transfected with either pTriEx2 or pTriCTGF-Rz and further stimulated with or without TGF-1.There were five groups in the experiment:control group,pTriEx2 group,pTriCTGF-Rz group,pTriEx2 plus TGF-?1 group,and pTrCTGF-Rz plus TGF?1 group.Semi-quantitative RT-PCR was used to detect the levels of CTGF mRNA and collagen Ⅰ mRNA.ELISA and flow cytometry were used to detect the levels of collagen Ⅰ secretion and cell cycle.Results Transfection of pTriCTGF-Rz into LX-2 cells reduced the CTGF mRNA and collagen Ⅰ mRNA levels as well as collagen Ⅰ protein level compared with pTriEx2 group(P
