SUMMARY Takayasu’s arteritis is a rare,idiopathic,chronic inflammatory disease.Its course is un-predictable,but slow progression is usual,leading to stenosis,occlusion,or aneurismal degeneration of the aorta or its major branches.We present the anesthesia management of pregnancy in four women ad-mitted to Peking University Third Hospital for caesarean section from year 2006 to 2015 complicated with Takayasu’s arteritis and review this disease with special reference to natural history,diagnostic criteria, classification,prognostic factors,and anesthesia considerations.Anesthesiological data were retrospec-tively analyzed for clinical manifestations,anesthesia process,perioperative complications,and pregnan-cy outcome.One patient received only epidural anesthesia,while the other three patients received com-bined spinal and epidural anesthesia (CSEA).Surgeries for all the four patients were successful with sta-ble vital signs.We found comprehensive examinations including whether the disease was in the active phase and the clinical classification of the disease before conception was recommended for patients diag-nosed with Takayasu’s arteritis.CSEA and continuous epidural block could be both used as anesthesio-logical method in patients with Takayasu’s arteritis.During the surgery,to avoid rapid hemodynamic fluctuations and protect the major organs’function is very essential to allow for a satisfactory outcome.

Objecfive To investigate the effects of endotoxin on nuclear factor-κB p65(NF-κB p65)mRNA expression and ahtosteron secretion in rat hepatic stellate cells(HSCs).Methods Cultured rat HSCs(HSC-T6)were divided into endotoxin-treated group and control group.Cells in endotoxin-treated group were exposure to 1 mg/ml.endotoxin.Aldosteron secretions of HSCs were determined by radioimmunoassay,and NF-κB p65 mRNA expressions of HSCs were detected by one-step RT-PCR.Results At 6,12,24 and 48 h,aldosteron secretions in endotoxin-treated group were significantly hisher than those in the control group(t=3.063,4.577,6.847 and 9.317,P<0.05),and the expressions of NF-κB p65 mRNA in endotoxin-treated group were also higher than those in control group(t=5.155,6.095,7.875 and 9.313,P<0.01).Aldosteron secretions and NF-κB p65 mRNA expressions in HSCs displayed a positive correlation(r=0.886,P<0.01).Conclusion Endotoxin can up-regulate the aldosteron secretion and NF-κB p65 mRNA expression in rat HSCs,which may be one of the mechanisms of liver fibrosis induced by endotoxin.

Objective:To investigate the effects of Origin-Preserving Decoction on the proliferation of marrow hematopoietic cells in aplastic anemia mice. Methods:Based on experimental AA models induced by Benzene and 60Co radiation in mice, the experiments including semi-solid colony culture (CFU-GM、CFU-E、BFU-E) and liquid culture (MTT Assay) were undertaken to investigate the effects of Origin-Preserving Decoction on the proliferation of marrow hematopoietic cells in AA mice. Results:Origin-Preserving Decoction (3g/kg) (ig.) could improve the outputs of CFU-GM, CFU-E and BFU-E in AA mice damaged by benzene and 60Co radiation: MTT assay showed that Origin-Preserving Decoction could stimulate the hematopoeisis of bone marrow of AA mice radiated by 60Co. Conclusions: Origin-Preserving Decoction has a good future for AA therapy.

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

Objective To explore the effect of fibroblast growth factor receptors 1-dominant negative strategy (FGFR1-DN) on alkaline phosphatase (ALP) activity of bone marrow stromal stem cells (BMSCs) after osteogenic induction.Methods BMSCs were transfected with eukaryotic expression plasmid pcDNA 3.1 (+)-DN FGFR1 and pcDNA3.1 (+)-FGFR1.The experiment was conducted in 4 groups:FGFR1-DN transfection group,FGFR1 transfection group,pcDNA3.1(+) empty vector transfection group and non-transfection group.The ALP activity of BMSCs was detected in logarithmic growth phase after osteogenic culture.The qualitative detection of ALP activity was carried out immunohistochemically while the quantitative detection by cALP kit.The ALP activity was compared between the 4 groups at 7 and 14 days after osteogenic induction.Results Compared with 7 days,the ALP activity at 14 days was significantly increased in the 4 groups,and the increase in FGFR1-DN transfection group was significantly higher than in the other 3 groups (P ＜ 0.05).At both 7 and 14 days,the ALP activity in FGFR1-DN transfection group was the highest while that in FGFR1 transfection group was the lowest (P ＜ 0.05).Conclusions FGFR1-DN can promote the ALP activity of BMSCs during osteogenesis.This may provide an experimental basis for the joint application of local gene therapy and tissue engineering and for construction of tissue engineered bone with better biocompatibility.

Objective To investigate the effects of continuous invasive mechanical ventilation combined with BAL on COPD patients with respiratory failure. Methods Sixty COPD patients with respiratory failure were divided into BAL and control group randomly. Control group were treated with sputum suction tube to aspire sputum and BAL group treated with BAL. The changes in the indicators were observed. Results The SpO2, airway peak inspiratory pressure and blood gas analysis were improved significantly compared with the control group (P < 0.01). The number of peripheral blood leucocytes and the level of CRP in BAL group were lower than those in control group at the seventh day (P < 0.01). The duration of invasive mechanical ventilation and hospital stay in BAL group was shorter than that in control group (P < 0.01) and there was no severe complication in both groups. Conclusion BALwith continuous mechanical ventilation support are safe and effective and shorten hospitalization time and improve the prognosis of COPD patients with respiratory failure.
