Objective To analyze the aetiological characteristics and bacterial susceptibility in chronic obstructive pulmonary disease (COPD) complicated with ventilator-associated pneumonia (VAP) after mechanical ventilation. Methods To review the clinical characteristics, aetiological flora and bacterial susceptibility in 28 patients complicated with VAP in the ICU in recent years. Results The incidence rate of VAP was 66.7％. 91 clinical bacteria and 10 mycete isolates were collected, 64 (80.3％) were Gram-negative bacteria (GNB) and 27(29.7％) Gram- positive bacteria (GPC). The dominant bacteria was Xanthomonas maltophilia in COPD complicated VAP. Conclusion The main kind of bacteria in COPD complicated VAP after mechanical ventilation was GNB, and all kinds of the bacteria showed high tolerance. More attention should be paid to the cultivate aetiological bacteria and bacterial susceptibility and select the most suitable antibiotics in the treatment of VAP.

A novel nucleic acid amplification method,termed loop-mediated isothermal amplification(LAMP),which amplifies DNA with high specificity,efficiency,and rapidity under isothermal conditions,may be a valuable tool for the rapid detection of infectious diseases.This method employs a DNA polymerase that have activity of strand displacement DNA synthesis and a set of four specially designed primers that recognize a total of six distinct sequences on the target DNA.LAMP can amplify a few copies of DNA to 109 in less than an hour.The final products are stem-loop DNA with several inverted repeats of the target and cauliflower-like structures with multiple loops.A positive reaction would be shown as a ladder-like pattern in a gel electrophoresis analysis.Because of the advantage,the LAMP method will be widely applied to research of nucleic acid,clinical diagnosis of infectious diseases and detection of genetically modified organisms etc.

Objective To investigate the relationship between vascular endothelial function and insulin resistance(IR) and the incidence of metabolic syndrome(MS).Methods A seven-year follow-up study was conducted in 583 simple obese subjects who were chosen in 2000.Body fat,blood pressure,lipid profile,plasma glucose,insulin resistance index(HOMA-IR) and endothelium- dependent dilatation(EDD) were measured before and after the follow-up.Results A total of 177 new cases with MS were found during this seven years,which was 33.78% of all subjects who were followed up in 2007.Cumulative incidence of MS among seven-year was 38.14% in the impaired EDD group and 48.11% in the impaired EDD with IR group,both rates were higher than that of the IR group(25.00%)(P

Comparative analysis of characteristic of species and esterase-isoenzyme of isolates of Polyporus umbel-latus from different regions were processed. The results indicated that isolates of Jizhaoling ( Z) and Zhushiling (ZJ) have significant differences in characteristic, and enzymatic band types of the two species also have significant differences. The homology at genetics between the two isolates is 0% , and consanguinity between the two i-solates is the farthest.

AIM: To study the causes of pyogenic granuloma after hydroxyapatite(HA) orbital implants.METHODS: HA orbital implants (250 cases) in our hospital (68 pegged implants) were reviewed.All patients were followed up from 18 months to 10 years. Implants were removed after medical therapy which was proved to be ineffective.RESULTS: Ten of 250 cases of HA orbital implants developed pyogenic granuloma. Pyogenic granuloma occurred in 1 unpegged implants patient and 9 patients after pegging and drilling of HA implantation over 4～7 years. The pyogenic granulomas were not controlled by medical therapy effectively. Implants were removed in 9 cases except 1 case denied removing and continued medical therapy.CONCLUSION: Pyogenic granuloma was serious complication that occurred after HA orbital implants. Partial vascularization, implant exposure, xenogenic sclera implant, pegging and drilling of HA implantation are risk factors that affect the development of pyogenic granuloma.Pyogenic granuloma hasn't relation with implanted peg material. Pyogenic granuloma denotes the potential implant infection, and all implants should be removed finally.

Objective Measurement of ankle brachial index (ABI) is a simple method of assessing lower limb arterial blood supply,while measurement of toe brachial index (TBI)has only been advocated as an alternative.The aim of this study was to obtain information about whether TBI should be taken in type 2 diabetes,even when ABI is normal,and to evaluate the relationship between TBI and atherosclerosis.Methods In a crosssection study,ABI,TBI,and carotid intimal-medial thickness (IMT) were measured on 979 outpatients with type 2 diabetes in Ruijin Hospital.Those with normal ABI (0.9 ≤ABI ＜ 1.3,n = 945) were divided into two groupsnormal TBI group(TBI≥0.6,n=893) and low TBI group(TBI＜0.6,n=52),and then the clinical and laboratory data were compared between these two groups.Furthermore,the relationship between TBI and atherosclerosis was investigated.Atherosclerosis was defined as the maximum IMT ≥ 1.1 mm.Results Low ABI and low TBI were detected in 1.3% and 6.6% of the patients,respectively.Comparison of the clinical and laboratory data between the two groups showed that age and HbA1C values were significantly higher in the low TBI group.Furthermore,TBI was inversely associated with IMT(β=-0.217,P＜0.01),an indicator for atherosclerosis of the carotid artery.Multiple logistic regression analysis revealed that decline of TBI was an independent risk factor of atherosclerosis (OR=1.30,95% CI 1.01-1.69,P＜0.05).Conclusion In type 2 diabetes,the decline of TBI is associated with atherosclerosis,indicating the necessity for diabetic patients to detect TBI,even when ABI is within normal range,in order to detect peripheral artery disease in early stage,and reduce the risk for atherosclerosis.
