Vascular cognitive impaiment (VCI) refers to a large class of clinical syndromes caused by vascular risk factors,obvious or not obvious cerebrovascular diseases from mild cognitive impairment to dementia.Looking for a physiologically controllable and repeatable animal model is critical for the systematic research of the VCI pathophysiological processes and the evaluation of new treatment methods.

The developments of domestic and foreign researches on mutagenesis of sulfur dioxide were briefly reviewed in this paper from different aspects: microbiological experiments, the experiments of cultured mammalian cells in vitro,experiments on mammal and population in vivo.

[Summary] Endometrial carcinoma is one of the most common malignant tumors in female reproductive system .The treatment is given priority to with surgery .As a kind of minimally invasive surgery , the da Vinci robot surgical technique has become more and more mature in the past ten years and played an increasingly important role in gynecological oncology .As compared with the traditional laparoscopic surgery , the main advantages of the da Vinci robotic surgery system are as follows: improved three-dimensional surgical field, improved operation dexterity by mechanical wrist , and improved accuracy of operation by tremor filtering system .These innovations can help gynecological oncologists complete difficult surgery , especially for patients diagnosed of endometrial cancer with severe obesity.This article summarized the application of the da Vinci robotic surgery system in the treatment of endometrial carcinoma and compared it with the open surgery and traditional laparoscopic surgery .The new robot surgery system , innovation, applicable people and the learning curve were also involved .

Objective To investigate the clinical manifestation and outcome of severe acute respiratory syndrome (SARS).Methods The clinical data of 233 patients with SARS admitted to China-Japan Friendship Hospital from April 2003 to June 2003 were analyzed,including clinical manifestations,laboratory findings,chest radiograph,outcome and mortality of SARS.Results There were 115 male and 118 female patients in this cohort,aged 13-86 (mean 42 8?18 5yr);43 3%of the patients had one or two kinds of underlying diseases;73 0% of the patients had a history of SARS close contact. Incubation period was 1-21 days (mean 4 9?4 1d).The initial symptoms were fever in 86 3% of the patients.The respiratory symptoms were found after the onset of 1-2 weeks.The laboratory abnormalities were decreased in WBC (56 7%) and lymphocytes (78 5%).Corticosteriod was used in 69 5% of the patients.There were 10 deaths (4 3%).The elder age,underlying diseases,continued high fever, thrombocytopenia,leucocytosis and bilateral lung involvement were the risk factors.Conclusion SARS is a new and strongly contagious disease,which mainly affects youth and people in their prime life.It has its own characteristic clinical manifestations.There is high mortality in severe cases.The prognosis is poor in patients complicated with diabetes,leucocytosis,lymphocytopenia,thrombocytopenia and elevated serum LDH and CPK.

Objective:To investigate the clinical value on the determination of the peripheral blood ICAM 1 level in Graves's disease(GD).Methods:The serum soluble Intercellular Adhesion Molecule 1(sICAM 1)concentration were analyzed by ELISA and the expression of ICAM 1(CD54 +) on PB lymphocytes in 37 GD patients and 22 normal subject were measured,while TsAb,TpoAb,TGAb;CD4 +,CD3 +,CD8 +,CD19 +,CD25 +were examined by FACS.Each marker between the two groups and the positive rate between the TsAb and sICAM 1 whe compared.In addition ,the relationship between the ICAM 1 level on PB and immunity markers in GD patients were analysed.Results:The mean sICAM 1 concentration was significantly higher in untreatd GD patients than in normal controls(P

Objective To learn the degree of the asthmatic patients'understanding of the disease, and to provide references for formulating the plan of the asthma patient's education and management infuture.Methods One hundred and one outpatients were surveyed by questionnaire face to face.Results Among 101 patients,the percentages of mild intermittent,mild persistent,moderate persistent and severepersistent asthma assessed by current symptom were 23%,29%,30%,18%.Among these patients thosewho understanding the inflammatory nature of asthma account occupied 70.3%,those who realizing the importance of inhaled corticosteroids(ICS)and taking ICS as the first-line medicine for asthma occupied67.3%,those who knowing the indication about rational use of short-acting beta-2-agonists(SABA)occupied 88.1%,those who realizing the goal of asthmatic therapy occupied 71.3%.All these results were significantly better than both the reporter in the asthma insights and reality in Asia-Pacific and the realizing degree to asthma of the respiratory professionals in Beijing's urban district hospitals in 1997.Conclusion After long term systematic education and management,asthmatic patient's understanding of the disease has been improved greatly.

Objective To investigate the effect of Omithogalum caudatum Ait(OCA)on apoptosis of Candida albicans,illustrated the antifungal mechanism of OCA.Methods Annexin Ⅴ-FITC/PI double stainingwas used to detect the effect of OCA on the apoptosis of C.albicans;JC-1 and DCFH-DA staining were used to detectthe effect of OCA on mitochondrial membrane potential(MTP)and reactive oxygen species(ROS)of C.albicans.Results OCA had a good antifungal activity,the minimum inhibitory concentration(MIC)and the minimum fungicidal concentration(MFC)were 8mg/mL and 32mg/mL respectively.OCA could induceapoptosis of C.albicans,promote the reduction of MTP and increase of ROS.Conclusion OCA induced cell apoptosismainly through disrupting mitochondrial function.

Objective The aim of this study was to investigate which inflammatory markers allow an accurate differentiation of septic and gouty arthritis.Methods In 2013 January to 2014 January 33 patients with septic arthritis and 29 patients with gouty arthritis.Detected white blood cells,C-reactive protein and uric acid of inflammatory markers in plasma and tested lac-tate,glucose,uric acid,lactate dehydrogenase and white blood cell count inflammatory markers in the synovial fluid.MedCalc 13.0 software were used for statistical analysis.Results There were no significantly different between serum C-reaction protein and WBC counts with two groups.Synovial lactate showed the greatest diagnostic potential (AUC=0.898,sensitivi-ty=96.9%,specificity=72.4%)followed by serum uric acid (AUC=0.818)and synovial uric acid (AUC=0.808).Con-clusion Lactate in the synovial fluid has excellent diagnostic potential to differ septic arthritis from gouty arthritis.Synovial lactate levers above 1.7 mmol/L almost proofed septic arthritis.

Objective The article was to promote the rational use of antibiotics by comparative analysis on antimicrobial us -age before and after the special rectification on clinical application of antibacterial drugs in our hospital . Methods Medical record data of 132 inpatients before the rectification and 167 inpatients after the rectification were randomly collected for the rational compara-tive analysis on microorganism submission rate for treatment , usage of antibiotics and medication for typeⅠandⅡincisions . Results The microorganism submission rate was much higher , especially the special grade antibiotics (81.5 %vs 32.1%).There was also a remarkable decrease in the percentage of antibiotics use , the strength of utilization and the average drug cost .The amount of antibiotic prophylaxis without indication and the length of medication for typeⅠincisions showed a remarkable decrease (P<0.05).Remarkable decrease was also observed in the irrational usage rate of antibiotic prophylaxis , dosage, medication time and drug replacement for typeⅠand Ⅱincisions (P<0.05). Conclusion The special rectification measures are effective and practical , which can promote the rational use of antibiotics .

Objective To research the relationship between anaemia and inflammatory in patients with heart failure .Methods 284 cases of patients with heart failure were enrolled and divided into 2 groups (anaemia group and non‐anaemia group) .The serum levels of of brain natriuretic peptide (BNP) ,high‐sensitivity C‐reactive protein (hs‐CRP) ,blood urine nitrogen (BUN) and creati‐nine (Crea) were measured ,and the results were analyzed .Results The levels of BNP ,hs‐CRP and Crea of anaemia group were sig‐nificantly higher than those of non‐anaemic group (P<0 .01) .The results of logistic regression demonstrated that hs‐CRP was in‐dependently associated with anaemia (P=0 .021) .Conclusion The occurrence and development of inflammation are independently associated with anaemia in the patients with heart failure .
