Objective To determine the clinical value of pulsed dual-wavelength 595 and 1064 nm laser in treating superficial infantile hemangioma. Methods The treatments were conducted in 260 patients with 270 lesions. The location of the lesions were 41 cases in scalp, 88 in face and neck, 79 in trunk and 62 in arms and legs. All lesions were treated several times with 595 nm (Group 1) and/or 1064 nm (Group 4) multiplex mode until the treatment was finished. The frequency of treatment was one to six times. The interval of the treatment was four weeks. Results The total effective rate was 95.56 %, with atrophic scar (8.15 %) but without severe ulcer. No significance was found as compared Group 1 parameter with Group 4 in formation of atrophic scars (x2 = 1. 870, P>0.05). Significant difference in the incidence of atrophic scars was found among different location of lesions (x2 = 15. 743, P<0. 01) : lesion in face had the highest probability. No obvious difference was found between different location of lesion and the frequence of treatment (x2 = 21.164, P>0.05), and so did with the efficacy (x2 = 11. 597, P>0.05). The size and the thickness of lesion had significant difference in the time of treatment (x2 = 58. 171, P<0. 01 and x2 = 11. 583, P<0.05, respectively).Conclusions 595nm/1064 nm dual-wavelength laser is a safe and effective tool for treating superficial infantile hemangioma. Choice of treatment parameter in the mode depends on the features of vascular lesions.

Objective To analyze the aminoglycoside ( AG ) antibiotics resistance rate of carbapenem-resistant Klebsiella pneumoniae ( CRKP ) and its molecular mechanisms.Methods One hundred and four strains of CRKP isolated from 4 hospitals in Zhejiang Province from January 2013 to June 2014 were collected, including 56 strains from Sir Run Run Shaw Hospital , Zhejiang University School of Medicine ( S hospital ), 22 from the First Affiliated Hospital, Zhejiang University School of Medicine ( Z hospital), 13 from Yiwu TCM Hospitals (Y Hospital) and 13 from Fuyang First People's Hospital (F Hospital).VITEK 2 Compact method and K-B disk method were used to detect the susceptibility of commonly used antibiotics including three kinds of AGs (kanamycin, gentamycin and amikacin ).PCR and sequencing techniques were used to screen the aminoglycoside resistance -related 16S rRNA methylation genes (rmtA, rmtB and armA) and the aminoglycoside modified enzyme resistance gene [aac(6′)Ⅰb].The relationship between drug resistance and carrier status of drug resistance genes was analyzed .Homologous analysis of rmtB-positive strains was performed using PFGE to examine the epidemic spread of strains in each hospital.Results All 104 CRKP strains were multi-drug resistant and had high resistance to cephalosporins, fluoroquinolones ( ciprofloxacin, levofloxacin ) and nitrofurantoin.The resistance rates to gentamicin, kanamycin and amikacin were 73.1%(76/104), 64.4%(67/104) and 56.7%(59/104), respectively.The carrying rates of aminoglycoside-resistance genes were: rmtB 56.7%( 59/104 ), aac (6′)Ⅰb 17.3%(18/104), armA 1.9%(2/104); while no rmtA was detected.Thirty-seven strains did not carry the screened genes.Amikacin-resistant strains were resistant to both kanamycin and gentamicin, and both were rmtB-positive strains.The PFGE classification results showed that 104 strains were divided into 11 clonal populations, and there were scattered non-population clones in each hospital. There were seven major clonal populations (Ⅰ-Ⅶ) carrying rmtB genes, of which typeⅠ, typeⅢand typeⅤwere prevalent in S hospital ; typeⅡ, typeⅥand TypeⅦwere popular in Z hospital ; the distribution of strains in Y hospital was scattered ; F hospital had one independent clone type Ⅳ(3 strains).Conclusion AGs still have certain sensitivity to CRKP strains.The main mechanism of strain resistance to AGs is the rmtB gene-mediated 16S rRNA methylase.

Hypoxia conditioning could increase the survival of transplanted neuronal progenitor cells (NPCs) in rats with cerebral ischemia but could also hinder neuronal differentiation partly by suppressing mitochondrial metabolism. In this work, the mitochondrial metabolism of hypoxia-conditioned NPCs (hcNPCs) was upregulated via the additional administration of resveratrol, an herbal compound, to resolve the limitation of hypoxia conditioning on neuronal differentiation. Resveratrol was first applied during the in vitro neuronal differentiation of hcNPCs and concurrently promoted the differentiation, synaptogenesis, and functional development of neurons derived from hcNPCs and restored the mitochondrial metabolism. Furthermore, this herbal compound was used as an adjuvant during hcNPC transplantation in a photothrombotic stroke rat model. Resveratrol promoted neuronal differentiation and increased the long-term survival of transplanted hcNPCs. 18-fluorine fluorodeoxyglucose positron emission tomography and rotarod test showed that resveratrol and hcNPC transplantation synergistically improved the neurological and metabolic recovery of stroke rats. In conclusion, resveratrol promoted the neuronal differentiation and therapeutic efficiency of hcNPCs in stroke rats via restoring mitochondrial metabolism. This work suggested a novel approach to promote the clinical translation of NPC transplantation therapy.
