Objective To sum up the characteristics of hemorrhagic fever with renal syndrome(HFRS)and acute pancreatitis,to improve the understanding of the cases of atypical HFRS,reduce the misdiagnosis rate and improve the cure rate.Methods 3 cases of HFRS complicated with acute pancreatitis in our hospital from 2011 to 2015 were retrospectively analyzed.Results 3 cases were middle -aged men,with an average age of 46.6,of which two cases occurred in Huangling county in the city,the remaining 1 case occurred in Yichuan county of the city. Occupation was the railway workers,drivers,farmers.Respectively occurred in February,July,December.3 cases of blood routine,urine routine,blood coagulation performance were consistent performance for RBC,WBC,PLT decrease;hematuria,proteinuria;3 cases of plasma amylase were higher than that of more than 3 times the normal value,the serum lipase was higher than the more than 3 times the normal value;hemorrhagic fever antibodies were positive;treatment of 2 cases with hemodialysis treatment,1 case underwent intestinal dialysis treatment,successful treatment of all.Conclusion HFRS with acute pancreatitis patients were less,easy to be misdiagnosed or ignored,easy illness of incur loss through delay and once with acute pancreatitis will add to the original condition,treatment more difficult tend to have higher mortality rate.It should be according to the clinical manifestations,early blood and urine amylase, abdominal B ultrasound and CT examinations of the abdomen as soon as possible,to improve the accuracy of diagnosis, take appropriate treatment measures,especially blood dialysis treatment,can reduce the mortality rate.

Tyrosinase is a key enzyme related to skin pigmentation disorders of elderly people, while self-aggregation of the amyloid-beta peptide, Abeta42, has been considered as a key event in the pathogenesis of Alzheimer's disease (AD). The present study was undertaken to investigate the inhibitory effects of 20 samples from Rhodiola species on tyrosinase and Abeta42 aggregation, and to isolate their corresponding bioactive components. The results demonstrated that the oligomeric proanthocyanidins (OPCs) commonly found in Rhodiola species were the major bioactive components corresponding to their anti-tyrosinase and anti-Abeta42 aggregation bioactivities. Salidroside, a representative compound of Rhodiola plants, proved not to be active in the present studies.

ING1 family is a candidate for tumor suppressor,which has three splicing isoforms named p47ING1a,p33ING1b,and p24ING1c. Study of the effect of different isoforms of ING1 on HeLa cells proliferation and its molecular mechanism would help further identifying the functional relationship of ING1 isoforms,and finding important genes regulated by ING1. Cell growth curve and cell cycle analysis were used to observe the effect of ING1a,ING1b,and ING1c on HeLa cells growth,and the result indicated that they could all inhibit HeLa cells growth by arresting cell cycle at G0/G1 phase. PCR method was used to construct the PHD domain deletions of ING1a and ING1b. ING1a,ING1b,ING1c and the PHD domain deletions 1a?C and 1b?C were then overexpressed in HeLa cells. p16INK4a,PTEN/p27Kip1 and p53/p21Waf1 protein levels were detected by Western blot. The result showed that ING1a,ING1b,ING1c,and 1a?C except for 1b?C induced p16INK4a protein expression,in which ING1c had the most powerful effect. Luciferase assay identified that overexpression of pcDNA3.1(+)-1a?C facilitated p16INK4a transcription through enhancing p16INK4a promoter activity,while pcDNA3.1(+)-1b?C repressed the p16INK4a promoter activity . In a word,it was found for the first time that except for the p53/p21Waf1 pathway,three splicing isoforms of ING1 family could also inhibit HeLa cells proliferation though upregulation of p16INK4a and PTEN,and the PHD domain deletion of ING1a enhanced p16INK4a transcription. These findings provide new clews to further study on the mechanisms of ING1 family suppressing cancer cells growth.

Angiogenesis is of great importance to a variety of normal physiological processes and pathological disorders.It is tightly regulated by many mechanisms, among which vascular endothelial growth factor(VEGF) is one of the most potent promoters.VEGF binds and activates its specific receptor tyrosine kinases, especially vascular endothelial growth factor receptor-2(VEGFR-2).VEGFR-2 mediates the key functional and biochemical effects of VEGF in endothelial cells including proliferation, migration, survival, and permeability.Following its binding to VEGF, VEGFR-2 dimerizes and undergoes autophosphorylation on tyrosine residues within its cytoplasmic portion.This creates docking sites for adapter molecules to be recruited through their Src homology domain-2(SH2).These adapter molecules can then initiate the activation of downstream signaling cascades.Further down-stream effector molecules are activated, and regulate the biological effects of endothelial cells.It is also foound that VEGF/VEGFR-2 signaling pathway may negatively regulate the function of human monocyte-derived mature dendritic cells(DCs) as well as the maturation of immature-DCs.Advances in the understanding of the VEGF/VEGFR-2 signaling pathway may contribute to the discovery of kinds of pharmaceutical agents.

Objective To compare influences of enteral nutrition (EN) and parenteral nutrition (PN) on the inflammatory factors and immune functions in patients with systemic inflammatory response syndrome. Methods Totally 85 patients who were treated in the First Hospital of Shanxi Medical University, Shanxi Province People's Hospital, and Taiyuan Central Hospital from April, 2006 to April, 2010 were enrolled in this study and divided into EN group (n = 49) and PN group (n = 36) according to nutrition support modes. The changes of inflammatory factors and immune functions after nutritional supports were recorded and compared between these two groups. Results The weight, arm circumference, skin fold thickness of brachial triceps, total protein, and serum albumin were significantly improved on the 7th and 14th day after nutrition supports in both two groups compared with the baseline levels (all P ＜ 0.05). On the 14th day after nutritional support, the levels of total protein and serum albumin were significantly higher in EN group than in PN group. On the 7th and 14th day, the levels of tumor necrosis factor-α, Interleukin (IL)-8, and IL-1β in EN group were significantly lower than those in PN group and baseline levels (all P ＜ 0. 05). The blood CD4/CD8 and IgG in EN group were significantly increased compared with the baseline levels and those in PN group (both P ＜0. 05). Conclusions Both PN and EN can effectively improve the nutritional status of patients with SIRS. EN has superior effectiveness in EN group than in PN group in terms of improving nutritional status, ameliorating immune function, and reducing the release of inflammatory factors.

Objective To propose a novel computer-aided segment algorithm, and retrospectively investigate its effect on radiologist's sensitivity and specificity for discriminating malignant masses from benign masses basing on ultrasound images. Methods Four hundred and sixty-six images of 100 masses obtained by conventional ultrasound were processed by a novel segment algorithm. Radiologists who were blind to the histology results were invited to analyse the original and computerized images respectively. The sensitivity and specificity were calculated by means of a binary outcome using receiver operating characteristic(ROC) analysis. Results By using the segment algorithm, the quantity of the image was obviously improved, especially the margin and calcification of the masses. The diagnostic performance of the radiologists was also improved. The sensitivity rose from 70.32% to 90.52% while the specificity was 74.31%. The area under the ROC curve increased significantly (P<0.01) from 80.8% to 90.5%. Conclusions The proposed segmentation algorithm can improve the diagnosis performance of the radiologists by meliorating the quality of the ultrasound image.
