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.

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.

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. Fortyeight healthy, aged 6 to 8 weeks C57/BL mice were involved.METHODS: The mouse model with pulmonary adenocareinoma was made with the method of inoculability of cancer cell, and then the models were group: On the following day of inoculation, 0.2 mL normal saline was used by gavage, and normal saline was injected intraperitoneally at the dosage of amine 20 mg was diluted into 0.2 g/L with normal saline, and performed intraperitoneal injection at the dosage of 5 μL/g, once per day, and 0.2 mL platinum diamine was used as in chemotherapy group and 0.2 mL qiongyugao was administered by gavage at the same time once per day. Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting were detected on the 21 days after administration.MAIN OUTCOME MEASURES: Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting of the mice in each group.RESULTS: Eleven mice failing to have tumor in tumor assessment were excluded from the sample, including 3 in the control group, 4 in the chemotherapy and 4 in the combination group. During the experiment,there were 2 mice dying in each group of the control group and chemotherapy group. Totally 11 mice in the control group, 10 in the chemotherapy group and 11 in the combination group entered the result analysis. Erythrocyte, leukocyte and blood platelets in the combination group and control group were all significantly higher than those in the chemotherapy group [erythrocyte: (8.54 ±0.81 ), (8.65 ±0.77), (4.56 ±1.00) ×1012 L -1;leukocyte:(9.04 ±0.60), (9.14 ±0.71), (3.31 ±0.96) ×109 L -1;blood platelets:(949.09±111.31 ), (955.54±87.13), (399.30±131.36)× 109 L-1 ,P ＜ 0.01]. The number of karyota in bone marrow in the chemotherapy group was significantly lower than those in the combination group and control group [(5.30±1.12),(10.51±1.15),(14.36±1.02)]×106,P ＜ 0.01); while the number of karyota in the control group was higher than that in the combination group (P ＜ 0.05).CONCLUSION: Qiongyugao can enhance the counting of erythrocyte,leucocyte, blood platelets of peripheral blood and karyota in bone marrow after chemotherapy in mice with pulmonary carcinoma, improve the inhibition of bone marrow induced by chemotherapy, but can not reverse it completely.

Idiopathic pulmonary fibrosis ( IPF) is a kind of Interstitial lung disease with cause unknown,which is aggressive for its increasing prevalence and high morbidity and mortality.At present the pathogenesis of IPF is not entirely clear, but cells and cel-lular interactions play a decisive role on the alveolar inflammation and fibrosis results.We review IPF related cells of interest ( immune competent cells and fibroblast, fibrocyte, myofibroblast, endothelial and alveolar epithelial cells) , to summarize cells and cellular in-teractions in the pathogenesis of IPF,and discuss new research directions and therapeutic targets.

Objective To evaluate the effects of docosahexaenoic acid ( DHA) on the expression of angiotensin?2 ( Ang?2) and vascular endothelial growth factor ( VEGF) in rat brain microvascular endo?thelial cells (BMVECs) subjected to oxygen?glucose deprivation (OGD). Methods Primarily cultured rat BMVECs were divided into 3 groups ( n=18 each) using a random number table: control group ( group C) , OGD group and DHA group. The cells were cultured with glucose?free and serum?free DMEM culture medium in OGD and DHA groups. In group DHA, DHA 40μmol was added, and then the cells were ex?posed to 1%O2?5%CO2?94%N2 in an air?tight incubator. The cells were cultured in the normal glucose and normal oxygen conditions in group C. All the cells were cultured for 24 h. Cell apoptosis was detected using Annexin V∕propidium iodide flow cytometry assay, and the apoptosis rate was calculated. The concentra?tions of Ang?2, VEGF, prostaglandin E2 ( PGE2 ) and prostacyclin ( PGI2 ) in the supernatant of the cul?ture medium were determined by enzyme?linked immunosorbent assay. The expression of Ang?2 mRNA and VEGF mRNA in cells was detected by real?time polymerase chain reaction. The expression of cyclooxygen?ase?2 ( COX?2) protein in cells was detected by Western blot. Results Compared with group C, the ap?
optosis rate and concentrations of Ang?2, VEGF, PGE2 and PGI2 in the supernatant were significantly in?creased, and the expression of Ang?2 mRNA, VEGF mRNA and COX?2 protein was significantly up?regu?lated in OGD and DHA groups (P<0.05). Compared with group OGD, the apoptosis rate and concentra?tions of Ang?2, VEGF, PGE2 and PGI2 in the supernatant were significantly decreased, and the expression of Ang?2 mRNA, VEGF mRNA and COX?2 protein was significantly down?regulated in group DHA ( P<0.05) . Conclusion DHA can inhibit the expression of Ang?2 and VEGF in rat brain BMVECs subjected to OGD and reduce cell apoptosis, and down?regulated expression of COX?2 protein is involved in the mecha?nism.

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.
