Objective To investigate the major risk factors of aseptic necrosis of bone in patients with systemic lupus erythemattrsus (SLE),and thus provide evidence for decision-making on prevention.Methods Meta-analysis Was used to systemically evaluate the 14 case-control studies about the risk factors of aseptic necrosis of bone in patients with SLE.Review Manager 4.2 Was utilized to carry out homogeneity checking and calculate the pooled odds ratio (OR) with 95% confidence interval.Results The OR values of risk factor of AVN in patients with SLE and 95% CI were as follows:Raynaud's phenomenon 2.43(1.12～5.29):dental ulcer 2.33(1.11～4.88);renal involvement 1.76(1.27～2.44);vasculitis 4.65(1.62～13.33):hyperlipidemia 3.28(1.76～6.12);anti-phospholipid antibody(APL)2.06(0.84～5.06):hypocomplementemia 0.63(0.35～1.14).Conclusion Glucocorticosteroid is an important risk factor in inducing aseptic necrosis of bone in patients with SLE,but it is not the only factor.Raynaud's phenomenon,dental ulcer,renal involve-ment,vasculitis and hyperlipidemia are major risk factors of aseptic necrosis of bone in patients with SLE.

AIM: To explore the biopharmaceutical character of the combination of Fructus Schisandrae and Radix Salvia Miltiorrhizae. METHODS: Mice were divided into four group according to schizandrol A, Schizandrin B, Fructus Schisandrae and combination with Radix salvia Miltiorrhizae and then perfused. Mouse's bood plasma was collected in sequence, and the test solusion was prepared by adding amine sulfate and the mixture of acetonitrile methanol (4∶1). Its contents were measure by HPLC in the aid of SIP and 3p97 program. RESULTS: Metabolic rate in mouse of schizandrol A and schizandrin B from combination is apparently lower than that of non combination. CONCLUSION: Chinese Traditional medicinal combination has its biopharmaceutical value.

Objective To study the clinical, laboratory, X-ray and the pathological features of Parkinson disease patients with rheumatoid-like deformities. Methods One patient was described and the relevant English literature in recent 50 years were reviewed. Results Rheumatoid-like deformities in Parkinson disease was mostly observed in women. The ratio between male and female was about 1:5.6. Joint deformities occurred after 7.6 years of Parkinson's disease in average. The manifestations of joints included the flexion of the metacarpophalangeal (MCP) joints, hyperextension of the proximal interphalangeal (PIP) joints, flexion of the distal interphalangeal (DIP) joints, and ulnar deviation of wrists and bilateral feet hallux valgus. Whole-blood analysis, biochemistry profile, erythrocyte sedimentation rate, C -reactive protein were all in normal range. Rheumatoid factor and ANA, anti-ENA profile, AKA, anti-cyclic citrullinated peptide (anti-CCP) antibody and antiperinuclear factor (APF) were all negative. Periarticular erosion was not observed in plaint X -ray films. Synovial pathology showed non -specific infla -mmation without classical syno vial membrane proliferation and pannus formation. NSAIDs and DMARDs were uneffective, but on the contrary, anti -parkinson' s disease therapy could relieve joints symptoms. Conclusion Parkinson disease can be accompanied with rheumatoid-like deformities which may be misdiagnosed as RA and should be differentiated from RA by laboratory, radiographs and synovium pathology examination.

Objective To establish a monitoring database of historical Oncomelania hupensis environments at grass?root lev?el for schistosomiasis prevention based on Google Earth(GE),so as to improve the management efficiency of historical O. hu?pensis environments. Methods GE was labeled with the information about the historical O. hupensis environments through add?ing landmark,path and polygon. Meanwhile,POCO web album was used to storage the practice situation pictures of the environ?ments,which could be imported into GE so that the environments could be monitored dynamically. Results There were 553 historical O. hupensis snail environments in Yangjian Town,Xishan District,Wuxi City and the accumulative area was 506 000 m2. Among these environments,224(40.5%)were Class IV environments,accounting for 40.5%of accumulative area. Conclu?sions The monitoring database of historical O. hupensis environments based on GE at country level is established successfully and it can be used to manage the historical snail environments visually and monitor the changes dynamically.

Objective To determine the improved effect of methylene blue(MB)on cognitive func-tion in brain-inflammatory-aging rats and investigate the underlying mechanism.Methods A total of 38 healthy 12-month-old SD rats were randomly divided into healthy control group,lipopo-lysaccharide(LPS)group,MB vehicle group and MB group,with 8 rats in the control and 10 rats in the other three groups.LPS was injected into the fourth ventricle with aid of a subcutaneous sustained release pump to establish a rat model of brain chronic inflammatory aging.MB of 0.5 mg/(kg·d)was added into the pump in the rats from the MB group.T-maze test and new object recognition test were employed to evaluate the learning and memory abilities of the rats.The acti-vation of microglia and astrocytes in the hippocampal CA1 region of the rats was detected by im-munofluorescence assay.The release of inflammatory factors IL-1β and IL-6 was measured by ELISA,and neuronal death in the CA1 region was assessed by neuronal nuclei(NeuN)fluores-cence staining.Results There was no significant difference in the exploration time for new and old objects between the LPS group and the MB solvent group(P＞0.05).The MB group spent significantly longer time in exploring the new objects than the old object(22.50±4.32 s vs 11.60± 3.01 s,P=0.000).The alternating selection rate of new arm and expression level of NeuN antigen were significantly decreased,and the expression levels of ionized calcium binding adaptor mole-cule-1(Iba-1)and glial fibrillary acidic protein(GFAP)and the contents of IL-1β and IL-6 were obviously increased(P＜0.05)in the LPS group and the MB vehicle group than the healthy con-trol group.Compared with the MB vehicle group,the MB group had notably increased alternating selection rate of new arms and higher NeuN expression level,and decreased Iba-1 and GFAP ex-pression and IL-1β and IL-6 contents(P＜0.05).Conclusion Subcutaneous administration of MB could significantly inhibit the damages of spatial learning and memory abilities in the LPS-induced brain chronic inflammatory aging rats.The mechanism may be closely associated with MB inhibi-ting inflammatory glial cells and protecting hippocampal pyramidal neurons.

Extracorporeal membrane oxygenation (ECMO) is a technique in which breathing and circulation are supported extracorporeally. Severe trauma may induce cardiopulmonary failure, for which ECMO can play an adjunctive role in the salvage treatment of circulatory and respiratory failure when conventional treatments are ineffective. Bypass with ECMO can rapidly improve the state such as circulatory failure and hypoxemia in critically ill patients in short term and can partially or fully replace their cardiopulmonary function in long term, winning valuable time for normal recovery of cardiopulmonary function. Because of the physical state of severe trauma patients and the ECMO equipment, there are still various complications clinically. Trauma patients show high risk of bleeding, vulnerability to wound infection and probability of combined organ injury and dysfunction, so more comprehensive measures for the prevention and treatment of complications during the use of ECMO therapy are required. The authors review the research progress in complications and corresponding prevention and treatment strategies during ECMO support for severe trauma, aiming to provide a reference to prevent and treat these complications.
