Objective To study the role of peptide with tyrosine(PYY) and ghrelin in infants by comparing the difference and correlation of PYY,ghrelin levels and body weight in preterm infants and full-term infants.Methods Radio-immunity was used to determine serum PYY and ghrelin levels in 20 preterm infants in their first,3rd and 7th days,and also in 20 full-term infants at the 7th day.Body weight were recorded in the both groups.Then the levels of 2 hormone were analyzed the correlations with the body weight.Results Serum PYY and ghrelin levels increased remarkably in preterm infants as compared with those in full-term infants[full-term infants:PYY was(601.9?206.2) ng?L-1;ghrelin was(1 064.5?208.6) ng?L-1;preterm infants:PYY was(812.4?153.8) ng?L-1;ghrelin was(1 485.4?409.2) ng?L-1,Pa

To test the hypothesis that dermal fibroblasts (DF) are an important source of cytokines which elicit major changes in hepatic synthesis of acute phase reactants(APRs). Metkods: Condi-tioned medium(CM) from human DF challenged with bacterial lipopolysaccharide (I,PS) was collected andIL-10 and IL-6 levels were measured- The ability of DF conditioned medium(fLPS) and dexamethasone(Dex) to mediate an hepatic acute phase response was tested on rat hepatoma H4 cells- Various concentra-tions and combinations of CM (?LPS), recombinant IL-6 (rhIL-6) and Dex were tested for their abilitiesto stimulate albumin, Q,-acid glycoprotein (AGP), a,-antitrypsin (AT) and transferrin mRNA synthesis.Results: LPS stimulated IL-6 production by DF and Dex inhibited this producti0n. IL-6 and CM+LPS in-hibited the production of albumin mRNA,while the expression of AT and AGP 0ccurred 0nly with CM+LPS+Dex. However,IL-6 alone had an inhibitory effect 0n albumin and transferrin mRNA producti0n.Dex maximized the effects 0f lL-6 and CM, and was essential f0r AGP gene expression. C0nclusion: (l)LPS-treated human DF can secrete IL-6, but not IL-101 (2)DF may als0 pr0duce other cyt0kines whichmodulate hepatic pr0tein synthesis during the acute phase response l (3) Dex inhibits IL-6 production byDF, but enhances its ability to stimulate the acute phase response.

Objective To explore the differences of memory functions and objective sleep parameters and their correlations in patients with insomnia disorder in different subtypes.Methods Eightynine patients with insomnia disorder,including 11 patients with difficulty initiating sleep(DIS),20 patients with early morning awakening(EMA),20 patients with difficulty maintaining sleep (DMS) and 38 patients with mixed sleep symptoms(MS) were enrolled between August 2012 and February 2014 in the Memory and Sleep Disorders Clinic of the First Affiliated Hospital of Anhui Medical University.Memory functions,including objective memory,spatial memory,working memory and reference memory were detected with nine boxes maze,and objective sleep profiles were assessed using polysomnography.Results The error numbers of spatial(H =15.404,P =0.002) and working (H =10.126,P =0.018) memories were significantly different among the 4 subtypes of patients,with more errors of spatial and working memory in the EMA (6.00 (5.00,8.00),5.00 (4.00,6.00)) and MS (5.00 (3.75,7.25),5.00 (2.75,7.00)) groups compared with the DMS (2.50 (2.00,4.00),2.00 (1.00,4.00)) group (tspstial =3.938,3.428;t =2.803,2.840;all P ＜ 0.05).Sleep efficiency(H =7.929,P =0.048),REM sleep time(F =2.840,P =0.043) and the percentage of REM sleep time on total sleep time (REM％;H =7.913,P =0.048) were also significantly different among the 4 subtypes of patients,with lower sleep efficiency in the MS(69.7％ (50.5％,78.7％)) group compared with the EMA (81.0％ (64.8％,86.4％)) and DMS (80.2％ (62.6％,88.9％)) groups (t =2.242,2.352;all P ＜ 0.05),less REM sleep time (min) and REM％ in the EMA(61.6 ±27.1,16.9％ (13.1％,21.9％)) and MS(56.9 ±31.4,16.9％ (11.5％,21.2％)) groups compared with the DMS (80.9 ± 32.7,22.3％ (18.5％,25.5％)) group (qREM time =3.791,5.397;tREM％ =2.513,2.612;all P ＜0.05).The error numbers of working memory and spatial memory negatively correlated with the REM sleep time (r =-0.387,-0.348;all P ＜ 0.05) and REM％ (r =-0.350,-0.354;all P ＜ 0.05).Conclusions There are discrepancies in the spatial and working memories and subtle differences in the objective sleep parameters among the patients with different subtypes of insomnia disorder.The worse memories in insomnia disorder patients might be associated with the decreased REM sleep.

BACKGROUND: Bone marrow inhibition is a predominant side effect caused by the drugs for anti-tumor.OBJECTIVE: To observe the intervention effect of traditional Chinese medicine qiongyugao on bone marrow inhibition induced by chemotherapy in experimental mice with pulmonary adenocarcinoma.DESIGN: Randomized controlled trial.SETTING: Medical College of Jinan University.MATERIALS: The experiment was completed in the Central Laboratory of Medical College of Jinan University from March to October in 2001.

Immortalized human precartilaginous stem cells (IPSCs) were established to provide stable cell resource for the study of the molecular mechanism of gene targeting on the differentiation of PSCs. Plasmid pCMVSV40T/PUR containing simian virus 40 large T antigen gene (SV40Tag) was transfected into human PSCs by using lipofectin transfection. Colonies were isolated by puromycin selection and expanded by multiple passages. Immunohistochemistry, RT-PCR and Southern blotting were used to identify the transfected cells and to detect the expression and integration of SV40Tag in expanded cell lines. The positive colonies were isolated and subcultured, designated immortalized precartilaginous stem cells (IPSCs), which were confirmed as fibroblast growth factor receptor-3 (FGFR-3) positive cells by immunohistochemistry and RT-PCR. SV40Tag cDNA was found in cultured IPSCs of passage 8 by Southern blotting, and the expressions of SV40Tag mRNA and protein were confirmed by RT-PCR. These findings suggested that IPSCs strain with SV40Tag was constructed successfully.

Objective:To identify the function of extracellular soluble vimentin that promotes proliferation, activation and chemotaxis of inflammatory cells. Methods: The proliferation of rat splenocytes stimulated with vimentin was evaluated in vitro. The lymphocyte counts and vimentin-antibody levels of peripheral blood in mice immunized with vimentin were detected in vivo. Peritoneal macrophages were collected and cultured with different concentrations of vimentin to detect the effect on phagocytosing chicken red blood cells. The chemotaxis of NIH3T3 fibroblast towards vimentin was observed in transwell chamber. Results:In vitro vimentin dose dependently promoted the proliferation of splenocytes. The proliferation indexes of primed and naive splenocytes cultured with 16μg/ml vimentin were reached up to ( 196. 0 ± 9. 7 )% and ( 208. 9 ± 4. 6 )% respectively without significant difference. In vivo vimentin significantly enhanced the lymphocytes number(109 L-1)of peripheral blood(5. 74±0. 51 vs. 1. 69±0. 13)and the levels of vimentin specific antibody( OD value 2. 31 ± 0. 06 vs. 0. 19 ± 0. 08 ) that shown no significant difference from immunization with vimentin plus CFA. In vitro vimentin dose dependently stimulated phagocytic ability of macrophages and performed the chemotactic effects on NIH3T3 fibroblasts. Conclusion:Extracellular soluble vimentin promotes the proliferation,activation and chemotaxis of concerned inflammatory cells and possesses the functions as an alarmin.
