Objective To estimate the application for the rapid identification of common clinical bacteria by MALDI-TOF MS. MethodsFour hundred and twenty-six bacteria, including Salmonella spp strains collected from Zhejiang center for disease control and prevention were collected from blood, sputum,secretion and urine in 2nd Affiliated Hospital of Zhejiang University during December 2008 to August 2009. The isolates included 76 gram positive coccus and 350 gram negative bacilli. Species identification was performed with the Vitek system, and serotypes of Salmonella and Shigella were determined by serum agglutination test. 16s rDNA gene of 91 bacteria were amplified by PCR. The RCP products were sequenced. Then the results were compared with the reported sequences from GenBank. All strains were identified by MALDI-TOF MS. Results of three identification methods were compared with each other. Results Among 426 tested isolates, identification results from Vitek system and MALDI-TOF MS for gram positive coccus and 323 out of 350 gram negative bacilli (exception for Salmonella and Shigella spp.),were identical. For 23 Salmonella and Shigella spp. , only 2 Salmonella enterica subsp, enterica serovar Typhimurium were identified the same results by the three methods. Besides, results from Vitek system and serum agglutination test for 1 Salmonella enterica subsp, enterica serovar Typhi, 3 Salmonella enterica subsp.enterica serovar Paratyphi A, 1 Salmonella enterica subsp, enterica serovar Paratyphi B, 1 Salmonella enterica subsp, enterica serovar Enteritidis, and 1 Salmonella enterica subsp, enterica serovar Bovis-morbificans were consistent with that from 16S rDNA gene sequence. Four isolates which were confirmed as S. flexneri by Vitek system and serum agglutination test were identified as Escherichia coli by both 16S rDNA gene sequence and MALDI-TOF MS. ConclusionMALDI-TOF MS could be used for rapid and accurate identification of common clinical bacteria with good repeatabihty, excepting for the Salmonella and Shigella spp.

Objective:To describe our diagnostic and therapeutic experience of patients with urinary tract endometriosis.Methods:We performed a retrospective analysis of 22 cases of urinary tract endometriosis with histopathological results from 2001 to 2007.Results:The mean patient age was 36.0 years.Of the 22 patients,4 had bladder involvement and 18 ureteral involvement.In those with bladder endometriosis,the diagnosis was made by cystoscopy and biopsy in 4 patients.The treatments consisted of partial cystectomy in 3 patients and transurethral resection of the bladder in 1 patient.One of the patients who underwent transurethral resection of the bladder experienced 1 relapse.The relapse was treated with partial cystectomy.In the patients with ureteral endometriosis,the diagnosis was mainly established by ultrasound(18 cases),intravenous urography(11 cases),retrograde pyelography(7 cases),CT(14 cases) and MRI(5 cases).The treatments consisted of ureterolysis in 1 patient,ureteroneocystostomy in 4,and ureteral resection and end-to-end anastomosis in 13 of them.All the patients pathologic results were of endome-triosis.Conclusion:Urinary tract endometriosis is an uncommon disease.Partial cystectomy should be considered as the therapeutic option for bladder endometriosis.For cases of ureteral endome-triosis,the first technique depends on the location,extent and depth of the lesion.

BACKGROUND:Previous research has shown that stem cells at different age stages had various proliferation and differentiation in vitro.Therefore,biological characteristics of bone marrow-derived mesenchymal stem cells at different age stages play a key role in evaluating differentiation into myocardial cells and determining proliferation and differentiation parameters in vitro.OBJECTIVE:To compare in vitro proliferation,surface marking,and differentiation into myocardial cells of bone marrow-derived mesenchymal stem cells from different aged rats.DESIGN,TIME AND SETTING:An in vitro contrast cytological observation was performed at the Laboratory of Biochemistry and Molecular Biology,Shanxi Medical University from May 2008 to May 2009.MATERIALS:A total of 15 healthy male Wistar rats were divided into three groups:1-month-old,3-month-old,and 12-month-old groups,with 5 rats in each group.METHODS:Bone marrow-derived mesenchymal stem cells were cultured using adherence screening method.At the third passage,cells differentiated into myocardium-like cells by the induction of 5-azacytidine.MAIN OUTCOME MEASURES:Cell proliferation was observed using MTT;cell surface marking was detected using flow cytometry;cardiac-specific myosin heavy chain mRNA expression was measured using RT-PCR.RESULTS:Bone marrow-derived mesenchymal stem cells were adherent in each group,and the proliferation curve was similar to each other.Under the same culture condition,the proliferation in the 1-month-old and 3-month-old groups was faster than 12-month-old group (F=28.71,P ＜ 0.05).The third-passage cells strongly expressed CD44 and CD71 but weakly expressed CD34 and CD45.At 2 weeks after 5-azacytidine induction,cardiac-specific myosin heavy chain mRNA was observed in all groups;however,the cardiac-specific myosin heavy chain mRNA expression in both 1-month-old and 3-month-old groups was significantly greater than 12-month-old group (t=5.140,2.827,P ＜ 0.05).CONCLUSION:With the age increasing of rats,proliferation,survival time,and differentiation of bone marrow-derived mesenchymal stem cells were weakened.

Objective To evaluate the capability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry ( MALDI-TOF MS) for rapid identification of methicillin-resistant Staphylo-coccus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) strains.Methods Twenty-five MRSA and thirty MSSA isolates were collected from the Second Affiliated Hospital of Zhejiang University School of Medicine as the experiment group .Twelve MRSA and twenty-two MSSA clinical strains were isola-ted as the control .All strains were identified by MALDI-TOF MS and the results were further analyzed by ClinProTools 3.0 software.Results Four algorithms including support vector machine (SVM), genetic al-gorithm ( GA) , supervised neural network ( SNN) and quick classifier ( QC) showed similar results in dis-tinguishing MRSA from MSSA isolates .The sensitivity of GA was 100 .0%and the sensitivities of other algo-rithms were all greater than 95.0%.The specificities of GA, SVM and QC were all greater than 90.0%. The areas under the receiver operating characteristic ( ROC) curves of four characteristic peaks at mass-to-charge ratios (m/z) of 3279, 6485, 6555 and 3299 m/z were all greater than 0.9.The virtual gel view showed that the bands generated by MSSA isolates at 3279 , 6485 and 6555 m/z were obviously deeper in color than those generated by MRSA isolates .However , the bands of MSSA isolates at 3299 m/z were appar-ently lighter in color than those of MRSA isolates .83.3%of MRSA and 90.0%of MSSA isolates from the control group were correctly identified by the GA model .Conclusion MALDI-TOF MS could rapidly and accurately identify MRSA from MSSA isolates under the strictly controlled experimental conditions with the advantages of less time-consuming, high sensitivity and high specificity .The accurate identification of MRSA from MSSA isolates could be applied for the prevention and treatment of MRSA infection .

As an important neurotransmitter, adenosine displays its functions by acting on the adenosine receptors. Recent studies have shown that the distribution, expression and balance among subtypes of adenosine receptors are closely related with cognitive activities, and changes of adenosine receptors play key roles in neurodegenerative disorders including Alzheimer's disease. It has been pointed out that prolonged activation of adenosine receptors by high level adenosine may lead to the disturbance of balance among adenosine receptor subtypes. This imbalance mainly performed as increased expression of A2a receptor and decreased expression of A1 receptor, and enhancement of the excitatory signals mediated by A2a receptor and weakened inhibitory signals mediated by A1 receptor. Changes of these two subtypes of adenosine receptors may lead to a lot of disorders of neurological activities which developed into dysfunction of cognition to the end. These findings imply that the potential of maintaining the balance among adenosine receptors on the treatment of AD would facilitate both the revealing of the mechanism and the cure of AD.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.
