Objectives To search for the pathogenesis of vaseular endothelial injury and its clinical significance.Methods 36 patients with acute lower respiratory trect infection(ALRI)and 30 healthy controls were envolved. Circulating endothelial cells (CEC)and nitric oxide (NO) levels were tested.Results Circulating nitrite/nitra levels,the stable metabolic products of NO,were found to be significantly higher in the patients with ALRI (44.6?22.6umol/L) than that in the controls (24.5?14.1umoI /L, P

Objective To evaluate and compare yeast identification ability between Bruker Microflex matrix-assisted laser desorption ionization-time of flight mass spectrometry( MALDI-TOF MS) and Vitek 2 Compact automatic microbial analysis system.Methods Retrospective study.Totally 742 strains of yeast isolated from clinical specimens during March 2013 to March 2014 in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine were identified by Bruker Microflex MALDI-TOF MS and Vitek 2 Compact automatic microbial analysis system simultaneously.The strains with discordant results were validated by gene sequencing.Results The coincidence rate of 699 Candida identified by Bruker Microflex MALDI-TOF MS or Vitek 2 Compact system was 100.0%(699/699) and 99.6%(696/699) to the species level, respectively and the coincidence rate of 43 yeast-like fungi strains identified was 90.7%(39/43) and 79.1%(34/43) to the species level, respectively.Penicillium marneffei could not be identified by both two instruments, but protein profile of Penicillium marneffei by MALDI-TOF MS was established.Conclusions The coincidence rate of yeast identified by Bruker Microflex MALDI-TOF MS is higher than that of Vitek 2 Compact system.Using Bruker Microflex MALDI-TOF MS to identify yeast especially Candida and yeast-like fungus is fast, simple, low-cost, accurate, and it can be used in routine work of ordinary yeast identification in clinical microbiology laboratory.

Objective To evaluate the safety and effectiveness of the treatment by selective β 1 receptor blockers on patients with chronic obstructive pulmonary disease (COPD).Methods Eighty cases of COPD Ⅲ (stable period) inpatient with or without coronary heart disease were collected in The Second People's Hospital of Shanghai from September 2012 to November 2013.The patients were randomly divided into testing group (Metoprolol treatment group) and control group (regular treatment group) with 40 cases for each group.Metoprolol group therapy based on the use of conventional metoprolol tablets,an initial dose of metoprolol 12.5 mg/d,titrated to the appropriate dose based on heart rate and tolerance of the morning resting heart rate of 55 to 60 times/min that reached the target dose of metoprolol continuous medication for 12 months.Blood gas analysis were recorded before and after treatment,pulmonary function,and 6 min walk test (6MWT) and were chronic lung disease Assessment Test (CAT) Rating.The control group was administrated regular treatment while the testing group added small dose of Metoprolol with titration to an appropriate dose on this basis.12 months in a row,and assessed the end stage.Results (1) After the application of selective β receptor blockers on testing group,no statistically significant difference (P＞0.05) in the values of FEV1 in anticipation value％ (testing group:(45.45 ± 4.68) ％ vs.(43.32 ± 4.84) ％;control group:(44.23 ± 4.68) ％ vs.(42.58 ±4.24)％),PaO2(testing group:(75.92± 10.78) mmHg vs.(74.86± 11.21) mmHg;control group:(70.23 ±6.45) mmHg vs.(72.36±7.28) mmHg) and PaCO2(testing group:(46.28±8.28) mmHg vs.(47.46±10.22) mmHg);control group:(44.54 ± 8.89) mmHg vs.(42.36 ± 7.45) mmHg) before and after treatment.But the 6MWD (testing group:(287 ± 23) m vs.(384± 34) m;control group:(284 ± 25) m vs.(295 ±21) m) and COPD appraisal test(CAT) (testing group:(21±7) score vs.(17±6) score);control group:(22 ±5) score vs.(20± 6) score) had improved significantly compared with that before treatment,with significant difference(t=4.903,4.784;P＜0.05).Conclusion Selective β receptor blockers have no effect on the airway resistance of COPD patients and reduction on pulmonary function.It can also increase the exercise tolerance and enhance the living quality for improving clinical prognosis.

Objective To observe whether immature Brain Derived Neurotrophic Factor (proBDNF)can affect the activities of OPCs in the fields of cell proliferation and migration after SCI,and to investigate the relationship between proBDNF and p75NTR signal pathway on OPCs.Methods OLN-93 cell line was cultured and maintained for in vitro experiments.Immunofluorescence were used to check the expression of endogenous proBDNF,p75NTR and sortilin on OPCs.MTT assay was used to illustrate the inhibitory effect of proBDNF.The effects of anti-proBDNF was also observed by BrdU staining to find a probably signal pathway for proBDNF on OPCs.The Sprague-Dawley rats were administered for T9 spinal cord injury animal model.BBB score was applied to observe the situation of functional recovery after treated by anti-proBDNF.BrdU staining was managed to observe the situation of OPCs proliferation and migration after SCI.Results Endogenous proBDNF inhibited proliferation and migration of OPCs after SCI.BrdU staining showed that population of proliferative OPCs in lesion site of spinal cord was less in proBDNF in treated group than that in control group and anti-proBDNF group.While anti-proBDNF could inhibit proBDNF specifically and might induced a better functional recovery which was illustrated by BBB scores.The in vitro experiments found the inhibitory effect of proBDNF is dose-dependent and can be neutralized by anti-proBDNF properly.Moreover,the expression levels of p75NTR and sortilin are down regulated by proBDNF antibody treated group.This indicated that proBDNF may inhibit OPCs via p75NTR pathway.Conclusion Endogenous proBDNF can inhibit cell proliferation of OPCs after SCI and can be neutralized by specific antibodies of proBDNF.This kind of detrimental effect may be induced by p75NTR-sortilin pathway.Furthermore,proBDNF antibody treatment is effective to block proBDNF and promote the functional recovery.
