Objective Discuss and analyze Staphylococcusaureus in isolation and drug resistance in patients with pediatric re-spiratory infection,providing guidelines for clinical treatment on the control of infection.Approaches collect 5 413 cases of respiratory tract infection from Jan.2013 to Dec.2014 in patients (including pediatrics neonatology)with sputum specimens, applying MicroScan-As4 automated Microbes Identification analyzer to identify and test drug sensitiveness of the separated strains,using Whonet 5.6 for statistical analysis.Results 1 540 strains of 29 different pathogenic bacteria were isolate from pediatric patients with respiratory tract infection,among which there were 336 strains (21.82%,336/1540)of Staphylococ-cus aureus (SAU,S.aureus),more than 1/5 of the total of pathogenic bacteria.And the isolation rate of pediatric respiratory tract infection accounted for 6.2 1%,significantly higher than that of other pathogenic bacteria isolation rate (with the excep-tion of Haemophilus influenzae>5%,the rest all<5%).In all detected SAU,methicillin-resistant Staphylococcus aureus (MRSA)occpied 59 strains (17.56%,59/336),which indicated that SAU played a leading place in patients with pediatric respiratory infection.The antimicrobial drug resistance rate of SAU against vancomycin,Nai thiazoleamine,daptomycin,and Quinupristin was 0,whereas to other antibiotics it showed different degrees of resistance.The drug resistance rate of MRSA to penicillin and ampicillin,oxacillin,ampicillin/sulbactam,amoxicillin/clavulanic acid and cefazolin,ceftriaxone was 100%,to erythromycin,clindamycin over 50%,to other antimicrobial resistance in low resistance.Conclusion There were more SAU in children with respiratory infection;especially MRSA bears multi drug resistance.Therefore,the monitoring of drug resist-ance of Staphylococcus aureus should be strengthened,and antimicrobial drugs should be rationally chosen according to the results of drug sensitive test for individuals,so that resistant strains can be under effective control and kept being reduced from emergence.

Objective To assess the clinical efficacy of electroanatomically guided mapping and radiofrequency ablation under CARTO system for premature ventricular contraction. Methods The CARTO electroanatomical mapping system displays real time three dimensional chamber structure with electrical information related to signal amplitude and activation time. Drugrefractory and frequent premature ventricular contractions were ablated under CARTO system. Results Frequent premature ventricular contractions were successfully ablated in all 8 patients with mean 2.2?1.7 radiofrequency applications under CARTO system. 6/8 frequent premature ventricular contractions occured in right ventricule, and 2/8 in left ventricule. After ablation, the premature ventricular contractions declined from 24 711?5 612 beats/24h to 0-5 beats/24h, and patient′s symptoms almost disappeared. No recurrent case was found during a period of 3-12 months following observation, and the premature ventricular contractions remained ≤10 beats/24h. Conclusions The CARTO electroanatomical mapping system, referred to the electrophysiologic data, may be applied in guiding the radiofrequency ablation of drug-refractory and frequent premature ventricular contractions in those patients who have no organic heart disease for its safety and accurate orientation.

Objective To investigate the distribution range and depth of the apocrine sweat glands of the axillary fossa,in order to supply with anatomic and histopathologic basis in the treatment on axillarv osmidrosis.Methods From December 2008 to ()ctober 2010,2 biopsy samples(with axillary osmidrosis),8 biopsy samples(normal,without axillary osmidrosis),were employed into the axillarv anatomy study. 25 patients with severe axillary osmidrosis were observed both maerographicallv and microscopically by using of operation and histopathological methods.Results Secretory portion of apocrine sweat glands was seen clearly,it was pitchy millet-like granules on axillary osmidrosis corpse,and pink millet-like granules in vivo.Secretory portions distributed most within the armpit hair area,exceeded the edge of armpit hair line,but not surpassed the edge of armpit hair line 1.0 cm.The depth of the apocrine sweat glands located vertically at superficial fat tissues between the dermal reticular 1aver and superficial fascia layers which were dissected away easily.Trimming with scissors under dermaIlayer,the secretory portion of apocrine sweat glands was removed cleanly without harms to reticular laver of dermas.Secretory portions became ducts under reticular layer of dermas.White Drominence-like granules were proved to be the compomers of hair follicle and sebaceous glands through Dathological section.Conclusions In order to treat axillary osmidrosis effectively,the secretary portion should be removed away through cutting off the tissues between the dermal reticular layer and suDerficial fastia layers;the ducts of apocrine sweat glands should be handled with removing hair follicle under the reticular layer of dermas．0peration area should not exceed 1.0 cm off the edge.

A collection of neurons in the upper lumbar spinal cord (lumbar segments 3 and 4) of male rats project to the lower lumbar spinal cord (lumbar segments 5 and 6) and release a gastrin-releasing peptide (GRP) to the somatic and autonomic regions, which are known to regulate male sexual reflexes. The GRP plays some special functions when bound to the specific GRP receptor (GRPR). The spinal GRP system is regulated by androgens. Accumulating evidence shows that GRP plays an important role in rat penile erection and ejaculation, and pharmacological stimulation of GRPRs with a specific agonist can restore penile reflexes and ejaculation in castrated male rats. Therefore, the GRP system appears to be a potential therapeutic target for the treatment of erectile dysfunction or ejaculatory dysfunction. The present paper briefly reviews the recent studies on the role of the spinal GRP system in regulating the sexual function of males.

ObjectiveTo evaluate the biocompatibility of a kind of scaffolding material,Injured Nerve Regenerated Materid(INRM), which play the roles of regeneration of nerve after traumatic brain injury.MethodsINRM scaffolding material were transplanted into cortex of rats after traumatic injury.The brain coronal sections were stained for Nissel, astrocyte and microglia at 1 week, 1 month, and 2 months after injury.ResultsThe presence of INRM did not alter patterns of astrocyte compared with the control group (detected with antibodies against GFAP) at any time point; but decreased the expression of microglias (detected with antibodies against OX42) compared with the control group.ConclusionThe biomaterial INRM is well suited as a biocompatible scaffold material for the repair of brain injury in the brain.

OBJECTIVETo observe the effects of acupuncture at "Tianshu" (ST 25) on electro-activity and mechanical motility at different phases of migrating motor complex (MMC) during jejunal digestion period in rats with detached jejunum, so as to explore the effect and mechanism of acupuncture on regulating intestinal movement.

METHODSSixteen adult SD rats were selected. Electrodes were implanted in the serous membrane of intestinal smooth muscl.e and high-sensitivity sensors of strain gauge were sutured on serosal surface, and then the rat was anesthetized and its jejunum was detached. Electro-acriviry and mechanical motility of jejunal smooth muscle were recorded simultaneously. Acupuncture was applied at "Tianshu" (ST 25) at MMC I , MMCII and MMC III, respectively, to observe its influence on electro-activity and mechanical motility.

RESULTSAt phase of MMC I, there was no obvious change of the fast wave before and after the acupuncture, while the frequency and amplitude of slow wave and mechanical motility were both significantly decreased compared with baseline (P < 0.01). At MMCII-Ill, the frequency and amplitude of fast wave, slow wave and motility were all significantly decreased compared with baseline (P < 0.01). Acupuncture at "Tianshu" (ST 25) had prohibited effects on electro-activity and mechanical motility of jejunal smooth muscle in rats with detached jejunum.

CONCLUSIONAcupuncture at "Tianshu" (ST 25) has obvious prohibited effects on electro-acrivity and mechanical motility at MMC I , MMC II and MMC III time phases in rats with detached jejunum. The possible mechanism is that acupuncture at "Tianshu" (ST 25) could prohibit jejunum movement through reflex path of skin-sympathetic.
