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.

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.

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.

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 investigate the change of microalbuminuria (MA) in patients with RA and its clinical significance.Methods:From January 2018 to December 2019, data of 75 cases of RA patients were collected from outpatient and inpatient wardsof our hospital, and the data of 75 cases of physical examination wascollected as control. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) anti-cyclic citrullinated peptide (CCP) antibody, blood lipid, Homeostasis model assessment for insulin resistance (HOMA-IR), rheumatoid factor (RF), anti-CCP antibodyand MA levels were measured respectively. RA patients were obtained by ultrasound Carotid intima-media thickness (cIMT) and brachial artery flow mediated diastolic function (FMD) were measured. The statistical analysis was carried out with independent t-test, analysis of variance, Pearson correlation analysis and multiple stepwise regression. Results:The MA level of RA patients was significantly higher than that of the healthy control group [(31±5) mg/L vs (25±4) mg/L, t=5.982, P<0.05]. In RA patients, MA level was positively correlated with course of disease ( r=0.327, P=0.015), HOMA-IR ( r=0.576, P<0.01], CRP ( r=0.212, P=0.027), RF ( r=0.585, P<0.01), disease activity score in 28 joints (DAS28) ( r=0.472, P=0.013), cIMT ( r=0.611, P<0.01) and duration of nonsteroidal anti-inflammatory drugs (NSAIDs) use ( r=0.274, P<0.01), and urineMA level( OR=1.763, P<0.01) were independent correlation factors affecting cIMT. Conclusion:The level of MA in RA patients is significantly higher than that in normal controls, and is correlated with disease activity and subclinical atherosclerosis, which could be another important predictor of disease follow-up and early screening of subclinical atherosclerosis in RA patients.
