Objective To investigate molecular typing and drug resistance patterns of 98 Klebsiella pneumoniae (K.pneumoniae) isolated from type 2 diabetes patients complicated with maxillofacial infection,to research the virulence and resistance mechanisms.Methods The study was a prospective study that adopted the method of continuous sampling from fixed location,from March 2010 to October 2012.The maxillofacial surgery patients diagnosed with type 2 diabetes complicated with maxillofacial infection were chosen in 7 hospitals in Zhengzhou as the research object,and a total of 431 pus sample were collected continuously,in which 98 strains K.pneumoniae were isolated and identified.The Kirby-Bauer disk diffusion test was conducted in 98 strains to determine the resistance to 19 antibacterial agents.K.pneumoniae chromosomal DNA were digested by restriction endonuclease Xba Ⅰ and analyzed by pulsed-field gel electrophoresis (PFGE).PFGE patterns of K.pneumoniae strains were analyzed using Fingerprinting software.The relationship between the molecular types and resistance phenotype was observed.The extended spectrum β-1actamase-producing K.pneumoniae were screened out by the double disc synergy test (DDST)Polymerase chain reaction (PCR) was used to detect resistant genotypes,serotype and virulence genes.The purified PCR products of resistant genes were cloned and sequenced.Hypermucoviscosity phenotype of all strains were determined by string test.Results Much severer drug-resistance for K.pneumoniae was identified and the result of extended-spectrum beta-lactamase producing rate was 57.1 %.Ninety-eight strains were dispatched into 13 groups by PFGE.No dominant bands and specific extended-spectrum beta-lactamase DNA bands were found.The results of PCR showed that among the 56 strains of extended spectrum β-lactamase-producing K.pneumoniae,40 were positive for blaSHV (accounting for 71.4%),28 positive for blaTEM (accounting for 50.5%),21 positive for blaCTX-M (accounting tor 37.5%).The sequencing results were as follows:TEM-1,CTX-M-3 and a variety of SHV.Serotype K1,K2,K3,K5,K20,K54 and K57 and 3 kinds of virulence genes were detected,but not in strong toxicity-based.Hypermucoviscosity positive rate was 31.6% (31/98).Conclusion Much severer drug resistance of K.pneumoniae in this study was identified and resistant mechanism was complex,in which strong toxicity serotype and virulence geues exist,which need more attention from clinical.

Objective To study the pathogenesis,diagnosis and treatment of the compression syndrome of the third common plantar digital nerves.Methods Conservative methods were at first used for all the 34 cases of this disease.Treatment methods includes:wearing shoes with soft bottom and metatarsal pad;the administration of Chinese herbs;the application of direct current iontherapy by filtering Chinese herbs and performing local injection therapy with steroid at the tenderness points.15 patients with no effect following conservative methods and other 3 recurrent cases were treated with section of deep transverse metatarsal ligament and relaxing the nerves compression.Of the 18 cases,5 had additional to excision of the neuroma.Results Of the 34 cases treated with conservative methods,19 had effective results,of which 6 cases recurred,and 15 cases had no effect.18 cases treated with operation had no recurrence.Conclusion Toe extending test and forefoot transversely compressing test provide a valuable basis for diagnosis.Conservative treatment are usually effective in earlier phase.If conservative treatment is not effective,the transverse metatarsal ligament should be sectioned,nerves should be relaxed and the neuroma must be excised.The results of operative treatment are satisfactory.

Objective To compare the concentration of 3-nitrotyrosine and tyrosine and the ratio of 3-nitrotyrosine/tyrosine in the cerebrospinal fluid (CSF) of patients with sporadic amyotrophic lateral sclerosis (SALS) and those with healthy nervous system for definiting the role of free radicals oxidative damage in pathogenesis of SALS. Methods Subjects consisted of 15 patients with SALS and 15 patients with norml nervous system who underwent lumbar anesthesia for surgery. Their CSF was analyzed by using high performance liquid chromatography (HPLC). Results The 3-nitrotyrosine concentration was higher in patients with SALS (228.52?124.30 nmol/L) than that in controls (112.86?47.10 nmol/L) (P

BACKGROUND: Two-dimensional electrophoresis (2-DE) is precise and effective for the isolation and analysis of complex protein mixtures, has become one of valuable key techniques for proteome. Mice models were as research subjects to model human disease status, one of important methods for cardiovascular disease. The establishment and optimization of 2-DE for proteomes of mice myocardium will provide basis for heart disease.OBJECTIVE: To establish and optimize a stable technique of 2-DE for proteomic analysis of mice myocardium.DESIGN: Mice were used as research subjects, observational comparative study.SETTING: Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University.PARTICIPANTS: The experiment was performed at the Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University between February and September 2004. Totally 12 male BABL/c mice of 4-5 weeks without special-pathogen free with the body mass of 12-15 g were selected, which was provided by the Experimental Animal Center of Southern Medical University.METHODS: The mice were put to death by dislocation of cervical vertebra under drugged state to obtain heart. Various protein extraction method,loading sampling buffer, strip range of IPG, sampling volume of protein,staining method and so on were compared, analyzed, scanned and digilized,and then performing image analysis. Each link in the study was established and optimized.MAIN OUTCOME MEASURES: Resolution of protein and reproducibility of the trial.RESULTS: A method that was optimal for cardiac tissue can isolate about a total of 910 protein spots on pH 4-7 gel strips. 200 μg was fit for silver stain while 1000 μg was for Coomassie stains. It was found that in the myocardium of normal mice about (920±30) protein spots were obtained in 17 em pH 3-10 L gel strip, while around (880±30) were gained in the pH 4-7 L gel strip. The mean matching rate achieves to 86. 9%.CONCLUSION: The findings of the trial showed that 2-DE technique can be effectively applied for proteomics of myocardium of mice to regulate and optimize, and relatively stable separation method of myocardial protein was established.

Objective To investigate the role of contrast enhanced ultrasound (CEUS) in detecting type Ⅰ and Ⅱ endoleaks after endovascular abdominal aortic aneurysm repair (EVAR).Methods PostEVAR patients who met the inclusion criteria were enrolled.All of patients underwent CEUS and computer tomography angiography (CTA) examination.The following parameters were evaluated:ultrasound contrast agent within aneurysmal sac,location and source of endoleaks,wash-in time of endoleaks and stentgraft since contrast agent injection.Analysis was performed to observe different types of endoleak features in CEUS.Results Nine cases were enrolled and all the cases had endoleaks.Three cases were type Ⅰ,6 cases were type Ⅱ.The wash-in time of type Ⅱ endoleaks delayed 9.8 seconds compared to type Ⅰ,and the results of CEUS diagnosis were consistent with CTA.Conclusions CEUS is an effective way to detect endoleaks.This technique can be used as a supplement for CTA in follow-up of post-EVAR patients.

ObjectiveTo explore the role of HSP27 in hepatic ischemia-reperfusion (IR) injury and hepatic ischemic preconditioning (IP).MethodsMale C57BL/6 mice were randomly divided into 3 groups:control group (sham operation),IR group (only hepatic IR),rHSP27 + IR group (rHSP27 injection before IR).The extent of liver injury was evaluated among these 3 groups.Murine HSP27 was silenced by short hairpin RNA and mice were subjected to IR with or without IP after interfering succeeded.Serum ALT and AST levels,hepatic histological damages and mRNA expression levels of pro-inflammatory mediators (TNF-α,IL-1β and IL-6) were measured.Results Silencing hepatic HSP27 aggravated IR injury indicated by higher concentration of serum ALT and AST (P<0.05),reinforced by severer histological damage and more expression of pro-inflammatory mediators (P<0.05),while injection of rHSP27 or IP ameliorated hepatic IR injury.Western-blot showed HSP27 expression was significantly higher in IP group than sham group.Silencing HSP27 largely removed the IP-induced hepatoprotection,indicated by restoration of caspase-3 induction.ConclusionHSP27 is an essential endogenous defense of liver against IR injury.Hepatic ischemic preconditioning can improve subsequent IR injury via up-regulation of HSP27,which is related to HSP27-mediated reduction of apoptosis.
