0 05,both).The mean level of COX 2 mRNA expression in active SLE group was significantly higher than that in normal controls ( P 0 05).Conclusion The level of COX 2 mRNA expression in active SLE group is markedly increased,which may be involved in the pathogenesis of SLE and provides a valuable scientific basis on the clinical use of specific COX 2 inhibitors.

Objective To investigate the anesthesia and perioperative blood management of patients with Marfan syndrome (MS) undergoing scoliosis surgery.Methods The clinical data of MS patients underwent scoliosis surgery from January 2013 to December 2015 in Peking Union Medical College Hospital were collected and compared with patients received the same surgery but without MS.Perioperative information and data on anesthesia and blood management were analyzed.Results Compared with control group,MS patients were found with more preoperative comorbidities with statistical significance,including eye disease,echocardiographic abnormalities,and ventilatory defects.MS patients had significantly more blood loss,more intraoperative and postoperative allogeneic and autologous blood transfusion.The operation time,anesthesia time,and length of postoperative hospital stay were all significantly longer in MS patients.Conclusions MS patients are common with multi-system involvement and comorbidities.Considering the high risk of perioperative bleeding,the anesthesia and blood management for MS patients undergoing scoliosis surgery should be with extra caution.Blood management should be applied and appropriate invasive monitoring methods should be considered when necessary.

Objective To assess the association between polymorphism within the interleukin-10 receptor cDNA gene (IL-10R) and Chinese patients with systemic lupus erythematosus (SLE). Methods The IL-10R genotypes of 94 SLE patients and 80 healthy subjects were examined by reverse transcription-polymerase chain reaction-single strand conformation polymorphism method (RT-PCR-SSCP), RT-PCR-restriction fragment length polymorphism (RFLP) and DNA sequencing. Results There were significant differences in the IL-10R2 genotype frequencies of these two groups. The IL-10R2 G520/G520 genotype increased the risk of developing SLE (OR = 0.515, 95% CI 0.414-0.579, P = 0.004) and individuals who had G520/A520 genotype also had a higher susceptibility to SLE (OR = 1.968, 95% CI 0.981-3.949, P = 0.055). There was no significant association between SLE and IL-10R1 genotypes. The risk of developing SLE was detected in the individuals who had the combination of IL-10R1 G241/G241 and IL-10R2 G520/G520 (OR = 0.515, 95% CI 0.444-0.597, P = 0.004). Conclusion The IL-10R2 genotypes of G520/G520 and G520/A520 as well as the combination of genotypes IL-10R1G241/G241 and IL-10R2 G520/G520 may increase the susceptibility to SLE in Chinese people.

Objective To evaluate the effect of losartan on mechanical ventilation-induced lung injury in diabetic mice.Methods Forty-eight female SPF C57/BL6 nice,aged 10-12 months,weighing 20-25 g,were randomly assigned into 3 groups (n =16 each):control group (group C).,diabetes + mechanical ventilation (group DM) and losartan group (group L).Diabetes mellitus was induced by intraperitoneal streptozotocin 150 mg/kg and confirmed by blood glucose level ＞ 16 mmol/L in groups DM and L.Diabetic mice were mechanically ventilated (FiO250％,VT 15 ml/kg,RR 70 bpm,PEEP 2 cm H2O) for4 h.Losartan 30 mg/kg was injected intraperitoneally 30 min before ventilation in group L.Eight mice from each group were chosen at 4 of ventilation and arterial blood samples were obtained for detection of PaO2.The animals were then sacrificed and the lungs were removed for determination of W/D lung weight ratio,myeloperoxidase (MPO) activity,pulmonary microvascular permeability,angiotensin Ⅱ (Ang Ⅱ) receptor AT1 mRNA expression (by RT-PCR),Ang Ⅱ content and nuclear factor kappa B (NF-κB) p65 expression (by Western blot).Results Compared with group C,PaO2 was significantly decreased,while W/D lung weight ratio,MPO activity,pulmonary microvascular permeability and Ang Ⅱ content were significantly increased,and the expression of AT1 mRNA and NF-κB p65 was up-regulated in groups DM and L (P ＜ 0.05).PaO2 was significantly higher,and W/D lung weight ratio,MPO activity,pulmonary microvascular permeability,Ang Ⅱ content and the expression of AT1 mRNA and NF-κB p65 were significantly lower in group L than in group DM (P ＜ 0.05).Conclusion Losartan can reduce mechanical ventilation-induced lung injury in diabetic mice through inhibiting AT1 receptor and Ang Ⅱ levels and improving pulmonary microvascular permeability and inhibiting NF-κB activation.

Objective To provide theoretical and experimental proof for selecting and implying Tourette's syndrome(TS) animal models, validities of four TS models induced by chemical factors were compared. Methods Four TS models,namely AMP model,APO model,DO1 model and IDPN model were built up by using different chemical modeling agents. Through detecting spontaneous movement, climbing time and monoamine transmitters levels in striatum, four TS animal models were compared and evaluated from three levels of validities-face, prediction,construct. Results Compared with control group, spontaneous movement times raised ( t = 4. 746, P =0. 000) and level of DOPAC ( (0.99 ± 0. 177 ) ng/mg) in striatum increased (P = 0.029 ), and level of NE in striatum decreased in AMP model group( (0.11 ± 0.033 )ng/mg, P = 0.012). Compared with control group, climbing time prolonged (P = 0. 004) and levels of DA ( ( 10. 19 ± 1.23 ) ng/mg), 5-HT ( ( 0. 54 ± 0.08 ) ng/mg) in striatum raised(P=0. 019, P=0. 002),at the same time ,levels of DOPAC( (0.63 ±0.11 )ng/mg),HVA ((0.45 ±0.04 ) ng/mg) in striatum reduced (P ＜ 0.01 ) in APO model group; Compared with control group, levels of DA ( ( 13.66 ± 1.55 ) ng/mg), DOPAC( (0.80 ±0. 11 ) ng/mg), HVA( ( 1.04 ± 0.14) ng/mg) grew downwards in striatum of DOI model mice(P=0.029,P=0.001, P= 0.004). Compared with control group, level of 5-HT in striatum increased in IDPN300 group ( (0.77 ± 0.09) ng/mg, P = 0.031 ). ConclusionFace validity of AMP model is temporal and that of IDPN model is steady and persistent. AMP model,APO model and DOI model possess predictive validity. AMP model,APO model,DOI model and IDPN model have potentiality of becoming construct validity model.

Objective To investigate the role of IL-6 and IL-6R in the pathogenesis of systemic lupus erythematosus (SLE) and its clinical significance. Methods RT-PCR technique was used to semiquantitatively analyze IL-6R mRNA expression in peripheral blood mononuclear cells (PBMC), and double antibody sandwich ELISA was applied to determine the serum level of IL-6 from 89 SLE patients . Results The positive IL-6R mRNA expression was found in each individuals among active SLE group (groupⅠ), inactive SLE group (groupⅡ) and control group (group Ⅲ). The mean levels of IL-6R mRNA expressions in groupⅠ,Ⅱ or Ⅲ were 0.902 ? 0.273, 0.519?0.11 and 0.573?0.24, respectively. Compared with group Ⅱand group Ⅲ, the mean level of IL-6R mRNA expression in groupⅠ was markedly increased (P = 0.00), while there was no statistical difference between group Ⅱ and group Ⅲ(P = 0.289). The mean serum levels of IL-6 in groupⅠ,Ⅱ and Ⅲ were 71.89 ? 20.02,17.96 ? 6.93, and 0.035 ? 0.035, respectively. Compared with group Ⅱand group Ⅲ, the mean level of IL-6 in groupⅠ was significantly higher than those in groupⅡ and groupⅢ (P = 0.00), while that in groupⅡwas higher than group Ⅲ (P = 0.00). There was a positive correlation between IL-6 and IL-6R in active SLE group and inactive SLE group(r = 0.887, and r = 0.615 P

Objective To compare the validity of four commercially available ELISA kits for detecting HSV-2 type-specific IgG antibodies. Methods A total of 125 serum specimens were collected from 105 patients with genital ulcers and 20 normal individuals without history of STDs. Four ELISA kits which are commercially available in China for the detection of HSV-2 type-specific IgG antibodies were selected for the evaluation. Western blot assay was used as the gold standard. Results Based on the results of detection by Western blot assay, the sensitivity and specificity of these ELISA kits including home-made 1, home-made 2, improted 1 and improted 2 were 13.1% and 98.4%, 7.5% and 100%, 100% and 11.1%, 87.7% and 96.7%, respectively. The areas under the ROC curve of three kits including home-made 1, imported 1 and imported 2 were 0.885 (0.822 - 0.948), 0.852 (0.747 - 0.902), 0.947 (0.950 - 0.998), respectively. Conclusions The results of imported 2 are well consistent with those of Western blot, while the results of other 3 kits are poorly consistent with those of Western blot. It is also indicated that the commercially available ELISA kits for detecting HSV-2 type-specific antibodies should be re-evaluated in terms of their validity befor being applied for the clinical diagnosis as well as laboratory research.

Objective To compare the experience of perioperative management and anesthesia in VHL syndrome and non-VHL patients undergoing pheochromocytoma resection .Methods 50 patients scheduled for surgical removal of pheochromocytoma in PUMC Hospital from 2009-01-01 to 2014-12-31 were included in this retrospective analysis . Among them,12 patients were diagnosed with VHL syndrome ,others were non-VLH patients.We focused on the clini-cal records , especially clinical manifestation , preoperative preparation , intraoperative anesthetic management , opera-tion duration and postoperative hospital stay .Results Comparing with non-VHL patients , VHL syndrome patients undergoing pheochromocytoma resection surgery were much younger , with multiple pheochromocytoma and a signifi-cantly increased norepinephrine release .The drug preparation period was much longer , as well as the operative time and hospital stay (P<0.05).But no statistical difference existed in the intraoperative hemodynamic fluctuation and the outcomes of the patients .Conclusions VHL syndrome patients mainly present with multiple pheochromocytoma which has more aggressive function .Since the long operation duration and high risk , the optimization of perioperative management and adequate drug preparation are the key factors to ensure the operation safety .
