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.

BACKGROUND: Medicine treatment of chronic respiratory failure achieved little effect. Interfering chronic respiratory failure of chronic cor pulmonale with noninvasive positive pressure ventilation (NIPPV) may be an effective measure to eliminate symptom and physical sign of patients.OBJECTIVE: To investigate the effect of nocturnal noninvasive positive pressure ventilation (NIPPV) on respiratory muscle function, pulmonary function of chronic respiratory failure patients with stable chronic cor pulmonale at high altitude area (HACCP).DESIGN: A completely randomized grouping design and randomized control trial.SETTING: Center of Respiratory Medicine, the 4th Hospital of Lanzhou Military Area Command of Chinese PLA.PARTICIPANTS: Totally 60 HACCP patients with chronic respiratory failure in stable stage, 38 male and 22 female, were admitted to Department of Respiratory Disease, the 4th hospital of Chinese PLA from October 2002 to November 2004. All cases, after informed consent was obtained,were randomly divided into two groups, including treatment group and control group with 30 cases in each group.METHODS: [1] Treatment group: Fitted with ventilator with pressure support ventilation (PSV) mode or positive end-expiratory pressure (PEEP)mode from 22:00 to next 7:00 every night. Before and after 5 weeks therapeutics, pulmonary function, arterial blood gas, respiratory muscle function and 6-minute walking distance (6MWD) were measured. Control group:Those were either assessed in inpatient objects stabled at least 1 week as control group before discharged and 5 weeks thereafter. [2] 6-minute walking distance (6MWD) test: Patients made their effects to walk 6 minutes in20 meters long corridor, or could not go on because of dyspnea, walking distance was determined. Using electronic diaphragmatic function meter,oral maximal inspiratory pressure (PImax) and maximal expiratory pressure(PEmax) were determined, then maximal transdiaphragmatic pressure (Pdimax) was measured with airway block method. With blood gas analyzer,partial pressure of oxygen in arterial blood (PaO2) and partial pressure of carbon dioxide in arterial blood (PaCO2) were assessed. With electronic spirometre, forced expiratory volume in one second (FEV1) expressed as percentage predicted (FEV1%), FEV1 forced vital capacity (FVC) ratio(FEV1/FVC) were assessed. [3] Differences between the groups in response to rehabilitation were identified using the unpaired Student's t test, while changes within groups were measured using the paired Student's t test.MAIN OUTCOME MEASURES: Respiratory muscular function, pulmonary function, arterial blood gas and 6-minute walking distance in two groups before and after intervention.RESULTS: All 60 chronic respiratory failure patients with stable chronic cor pulmonale were involved in-the analysis of results. Every parameters of blood gas and pulmonale function in two groups were similar before intervention (P ＞ 0.05). After 5-week intervention, PaO2, FEV1%, FEV1/FVC,PImax, PEmax, Pdimax and 6MWD were higher than before in treatment group and those in control group (P ＜ 0.05-0.01). PaCO2 after therapy was lower than before in treatment group and that in control group after treatment (P ＜ 0.01).CONCLUSION: Nocturnal NIPPV can markedly improve the arterial blood gas and pulmonary function, and increase respiratory muscle strength.

Objective To explore the prevalence,subtype,distribution characteristics and risk factors of IBS met ROME Ⅲ criteria in local adult residents of Shanghai Songjiang area.Methods With multi-stage,stratified cluster random sampling method,from April to May in 2010,residents of45 shanghai Songjiang communities were interviewed by questionnaire survey.IBS diagnosis was based on Rome Ⅲ criteria,and the subtypes were according to Bristol stool scale.Self-rating anxiety scale (SAS),self-rating depression scale (SDS) and Athens insomnia scale (AIS) were also simultaneously finished. Results There were 7648 individuals who completed the survey with qualified questionnaires; the efficient rate was 90％. The sample size accounted about 1.62％ of total population in Shanghai Songjiang area.Total 970 patients were detected,who met the Rome Ⅲ criteria,of those 492 males and 478 females.The adjusted prevalence of IBS was 13.1％,13.8％ in males and 12.7％ in females.The ratio of male to female was 1 ∶ 0.92.There was no significant difference in detection rate between males and females (P＞0.05).The prevalence was highest in the 18 to 29 years age group (18.2％,P=0.000).IBS unsubtyped (IBS-U) was the most common type in patients who met the Rome Ⅲ criteria (45.3 ％),IBS with diarrhea (IBS-D) type was more common in male (27.0％) and IBS with constipation (IBS-C) was more common in female (19.5％).The IBS prevalence of obesity group (x2 =4.046,P=0.044),higher education group (x2=31.210,P=0.000),mental group (x2 =8.409,P =0.015),unmarried group(x2 =26.933,P =0.000) and no abdominal surgery history group(x2 =5.894,P=0.015) was higher than that of control group.The risk of IBS prevalence in those who had the history of gastrointestinal infection,abdominal surgery,taking antibiotics or analgesics increased by 5.105,3.388,2.949 and 2.811 times respectively(P=0.000).Multivariate analysis indicated that the risk of IBS prevalence was increased by 1.69 times if took more spicy food,however high-protein diet was a protective factor (OR=0.900,P=0.000).Anxiety (OR=2.452,P=0.000) and insomnia (OR=1.923,P=0.000) were also risk factors of IBS.Conclusion IBS is a common and frequently occurring disease in Shanghai Songjiang community.The history of gastrointestinal infection,abdominal surgery,taking antibiotics or analgesics,intake of more spicy food,anxiety and insomnia may be risk factors of IBS.

Objective To investigate the clinical characteristics,diagnosis,treatment and prognosis of malignant ovarian germ cell tumors(MOGCT)with lung metastasis.Methods Fifteen patients of MOGCT with lung metastasis treated in Peking Union Medical College Hospital from Jan.1982 to Dec.2010 was retrospectively analyzed.Results(1)Clinical characteristics: the average onset age of these 15 patients is(23 ± 11)years old(6-48 years).The majority of these patients presented with abdominal pain(8/15)or irregular vaginal bleeding(4/15)as their initial symptoms.The primary tumor located in the left ovary in 8 cases,right ovary in 6 cases,and both sides in only 1 case.Metastatic lesions were confined to the lung in 12 patients,while the other 3 patients were found to have multi-site distant metastasis.(2)Diagnosis:all 15 cases included 9 pure non-gestational ovarian choriocarcinoma(NGOC),3 MOGCT containing choriocarcinoma component(one mature teratoma with choriocarcinoma component,one endodermal sinus tumor with embryonal carcinoma and choriocarcinoma components,one choriocarcinoma with dysgerminoma component),2 embryonal carcinoma,one immature teratoma.Only one patient in these 15 cases was correctly diagnosed before surgery.(3)Time of lung metastasis: of 12 MOGCT with choriocarcinoma component,11 patients were found to have lung metastasis in the course of their primary treatment,only 1 had lung metastasis 2 months after the synthetic treatment finished.Three MOGCT patients without choriocarcinoma component were all found to have lung metastasis when tumor relapsed in the advanced stages of the disease.(4)Treatment:all 15 patients received multi-agent chemotherapy combined with surgery.The mean courses of chemotherapy for these patients were 16 courses(5-43 courses).(5)Prognosis:of these 15 cases,complete remission was obtained in 10 patients of NGOC or mixed ovarian germ cell tumors with choriocarcinoma component,3 patients(one NGOC,one endodermal carcinoma and one immature teratoma,respectively)died in the course of treatment as result of tumor progression,2 progressed cases(one NGOC and one endodermal carcinoma respectively)abandoning therapy were lost to follow up.Conclusions MOGCT with lung metastasis are more often to found in NGOC patients.These patients could obtain high complete remission rate after standard multi-agent chemotherapy combined with surgery.The prognosis of MOGCT with lung metastasis containing choriocarcinoma component are better than that of those without containing choriocarcinoma component.
