Objective To construct an eukaryotic recombinant plasmid with HGFSP, a hybrid gene encoding the antigen epitopes of MSA1, MSA2, RESA and CSP in different developing stages of Plasmodium falciparum(P.f. ). Methods HGFSP was sub-cloned into an eukaryotic expression plasmid pcDNA3 from a prokaryotic recombinant plasmid pSK-HGFSP to construct the eukaryotic recombinant expression plasmid pc-HGFSP. The identified recombinant was then transfected into HepG2 cells with liposome-mediated method. The G418-selected positive cell clones were tested to identify the immunogenicity of HGFSP-expressing antigen. Results It was evidenced that HGFSP was correctly inserted into pcDNA3 by restriction enzymes map analysis. HGFSP-expressing antigen-specific fluorescent response was observed in pc-HGFSP-transfected HepG2 cells. The results of SDS-PAGE and Western-blotting showed that there was a 23 kD protein band, which can be specifically recognized by anti-sera of HGFSP-expressing protein in pc-HGFSP-transfected HepG2 cell lysis. Conclusion Pc-HGFSP, an eukaryotic recombinant plasmid encoding hybrid antigen epitopes of P.f ., was constructed successfully and the antigenicity of pc-HGFSP-expressing protein was confirmed.

[Objective]To compare spontaneous correction of the unfused thoracic curves after selective anterior versus posterior fusion in Lenke5 adolescent idiopathic scoliosis(AIS). [Method]A total of 72 Lenke5 AIS patients were rescruited from May 1997 to October 2005.Out of them,40 received selective anterior fusion(group A) and 32 received selective posterior fusion(group B).All had a minimum of 2-year follow-up.[Result] No complication were found in both groups at the latest follow-up.The thoracic curve was corrected from 30? to 16? for group A,33? to 18? for group B.Both groups had a better spontaneous correction of the unfused thoracic curves.The correction rate had no significant difference between groups.However,the thoracic curve was increased in four patients(2 in each group;group C),which resulted in trunk imbalance.The thoracolumbar/lumbar thoracic(TL/L:T) Cobb's ratio averaged 1.09 in the four patients whereas 1.59 in other 68 patients(group D).The flexibility of the thoracic curve had significant difference in group C and D(34.2% vs 57.3%).[Conclusion]Both of the surgical treatments can get a better spontaneous correction of the unfused thoracic curves.It is important to evaluate the.thoracolumbar/lumbar–thoracic(TL/L:T) Cobb's ratio and the flexibility of the thoracic curve before selective fusion.

AIM: To investigate the association between cycloxygenase-2 (COX-2) expression and VEGF intervention as well as the inhibitory effect of Meloxicam on the cultured human pterygium fibroblasts (HPF).METHODS: Expression of COX-2 was measured by immunohistochemistry in the cultured HPF from twenty excised pterygium cases. Expression of COX-2 in HPF was measured by Western blot following the treatment of vascular endothelial growth factor (VEGF) at the different concentrations. In addition, the effect of Meloxicam on proliferation of HPF was studied by adding the different concentrations into the cultured HPF plates by Mono-nuclear cell direct cytotoxicity (MTT) reduction assay.RESULTS: COX-2 expression was present in the cultured HPF. The level of the expression increased following VEGF treatment. The proliferation of the cultured HPF decreased following addition of the different concentrations of Meloxicam (from 75μ mol/L to 300μ mol/L) and the magnitude of the inhibition was dose-time dependent.CONCLUSION: COX-2 levels in the cultured HPF werepositively associated with VEGF stimulation and Meloxicam was inhibitory to HPF proliferation.

Objective To study the mechanism of restenosis for the prevention and treatment by PTA (percutaneous transcather angioplasty) through establishing an model.Methods Under median cervical incision, to eplore right rabbit carotid artery and then clip the segments of ICA at the origination and CCA near the cardiac side of bifucation, balloon catheter with guided wire were finally inserted from proximal cardiac side of the ligated ECA to perform TA after withdrawing the clipper. Histological and morphological analysis with the controll of normal left CCA were carried out during different follow up periods. Results Histopathological and morphometric analysis indicating thrombosis was the main changes in early stage and followed by VSMC from media to intima and irregular proliferation leading to obviously intimal thicking and restenosis at 15 days after PTA.Conclusions This experimental study show low mortality, high practicability and good reproducibility of the model as an ideal presentation for study the mechanism and the prevention of restenosis.

Objective: To investigate the factors that affect the outcome of pregnancies complicated with critically heart disease admitted to obstetric Intensive Care Unit (ICU). Methods: A retrospective study was conducted for 188 pregnant and postpartum patientscomplicated with heart disease who were admitted to the ICU in West China Second University Hospital from July 2009 to March 2013. Results: During the 4 years, there were 619 cases of pregnancy complicated with heart disease hospitalization. Among them, 188 (30.37%) patients complicated with severe heart disease were admitted to the ICU, accounting for 39.17% of the total ICU admission (480); the mean maternal age was (28.45±6.08) years old and the mean gestational time was (36.03±4.19) weeks. 23 (12.23%) patients received regular antenatal care in our hospital. 61 (32.45%) patients never received antenatal care before hospitalization. Among them, 5 patients were dead. hTe ratio for diagnosis of heart disease before pregnancy, during pregnancy and atfer admission were 39.89%, 25.54% and 34.57%, respectively; the most common heart diseases during pregnancy were congenital cardiac disease (80, 42.55%) and rheumatic heart disease (45, 23.94%) followed by arrhythmias (20, 10.64%). The most common complication were pulmonary arterial hypertension (51, 27.13%), arrhythmias (47, 25.00%) and severe heart failure (30, 15.96%); the cardiac function of 164 (87.23%) patients was at stage I–II and 5 (2.66% ) patients died when discharged from hospital. 151 (80.32%) patients received multidisciplinary consultation and 34 (18.09%) used central venous catheterization to control central venous pressure (CVP). 21 (11.17%) patients required mechanical ventilation. 11 (5.85%) patients required emergency life support (cardiopulmonary resuscitation 9 + electric deifbrillation 3). Conclusion: Pregnancy complicated with heart disease is the leading reason for admission to ICU. hTe congenital cardiac disease, rheumatic heart disease and arrhythmias are the main heart diseases during pregnancy. Multidisciplinary cooperation and intensive care are the key measures to improve the outcomes of patients with critically illness. It is very important for reduction of the maternal mortality rate through strengthening preconception care and antenatal care.

OBJECTIVE To investigate the effect of norepinephrine (NE) on expression of interleu?kin-6 (IL-6) in human macrophages and explore its pro-inflammatory and pro-atherosclerotic mecha?nisms. METHODS Murine U937 macrophages were cultured and stimulated with 0.01-10μmol·L-1 of NE for 6, 9, 12, 24 and 48 h. The IL-6 mRNA level of 24 h was analyzed by RT-PCR, and IL-6 protein expression in the supernatant at 0, 6, 9, 12, 24 and 48 h was detected by ELISA. After 24 h, intracellular reactive oxygen species (ROS) generation was observed by DCF fluorescence. The cells were pretreated with antioxidant N-acetylcysteine (NAC), complexⅡinhibitor thenoyltrifluoroacetone (TIFA) and NADPH oxidase inhibitor diphenyleneiodonium (DPI) for 1 h, and stimulated with different concentrations of NE for 24 h, before the level of IL-6 protein was detected by ELISA. RESULTS The expression of IL-6 mRNA and protein increased with the concentration NE 0.01-10 μmol · L-1 and incubation time. IL-6 mRNA and protein levels in macrophages were 2.62 and 4.47-fold those in cell control group when treated with NE 1.0μmol·L-1 for 24 h. Meanwhile, as the concentration of NE increased, the generation of ROS was 1.87, 2.56, 2.91 and 5.36-fold that of cell control group (P<0.01). NAC 10 mmol · L-1 and DPI 10 μmol · L-1 significantly antagonized the effect of NE on IL-6 expression, but TIFA had no effect. CONCLUSION NE upregulates IL-6 expression, which may contribute to the formation and develop?ment of atherosclerosis via ROS mediated by NADPH oxidase in macrophages.
