Objective To discuss the clinical manifestations and CT findings of eosinophilic cystitis in chidren.Methods Nine cases including Six boys and 3 girls,three to 13 years old,mean age of 8.3- year,have symptoms of hematuria,irritative voiding,dysuria and abdominal pain。The eosinophilic cystitis was pathologically proved in 7 patients and eosinophilic granulomatous cystitis in 2 patients,which based on cystoscopic tissue biopsy or surgery retrospectively.Results Local thickened bladder walls or nodular and sessile masses along the bladder dome showed in four cases with eosinophilic granulomatous cystitis,and the diffusely irregularly thickened bladder walls showed on CT scans in the rest 5 cases with eosinophilic cystitis.Conclusion CT findings are helpful to reveal the site,size and other features of eosinophilic cystitis in children.But biopsy of the lesion is necessary to rule out other bladder tumor and selecting the proper management.

Objective To explore the possible effect of combined treatment of zoledronic acid and doxorubicin on proliferation,invasion and adhesion of SGC7901 cell line,and potential underlying mechanisms. Methods MTT and Transwell experiments were used respectively to investigate the effect of different concentrations of zoledronic acid and doxorubicin on the proliferation,adhesion and invasion of SGC7901. The mRNA levels of MMP2, TIMP2, MMP9, ICAM1 and CD44 were quantified by real time PCR. Results Gastric cell line SGC-7901 were incubated with zoledronic acid for 48 h in different concentration of 10-6,10-5,10-4,10-3 mol/L,their inhibition rates were 4.98％,12.19％,27.34％ and 73.13％ separately,which were higher than control group (P＜0.01),and enhanced along with the dose increasing and the time extension (P＜0.05).Gastric cell line SGC-7901 was incubated with zoledronic acid 10-4 mol /L and doxorubicin 0.5 mg/L,respectively,or in combination for 2 h,4 h,6 h,and thereafter,the detected adhesion rates were 5.03％,24.38％ and 59.65％ in control group,4.40％,19.77％ and 51.22％ in zoledronic acid group,4.28％, 18.62％ and 51.02％ in doxorubicin group,4.02 ％,15.02％ and 46.95％ in combination group. The adhesion rates were reduced after incubation with different medicament concentration (P＜0.05).In the study of cell invasion,the cell numbers per high power field were:105.11 ± 10.43,98.37 ± 15.75,96.19 ± 9.24,83.02 ± 19.72 after treatment with zoledronic acid,doxorubicin or their combination at different concentrations. Compared with control, signal medicament had weak effectiveness in invasiveness in SGC-7901 (P＞ 0.05),whereas in combination group it was significantly decreased (P＜0.05).Both zoledronic acid and doxorubicin decreased the mRNA expressions of CD44,MMP2,MMP9,ICAM1 while increased TIMP2 mRNA level (P＜0.05or P＜0.01) versus control.The effect was more evident with combination treatment(P＜0.05 or P＜0.01),compared with doxorubicin group. Conclusions Both zoledronic acid and doxorubicin can inhibit the proliferation,adhesion and invasion of SGC7901. Combination treatment has additive effect.It may be related to the down-regulation of mRNA of ICAM1,MMP2,MMP9,CD44 and up-regulation of mRNA of TIMP2.

Objective To investigate the effect of resistance nodulation division (RND) efflux pumps on reduced susceptibility to tigecycline in carbapenem-resistant Acinetobacter baumanii.Methods Totally 631 isolates of Acinetobacter baumanii were collected from 16 hospitals in 7 provinces in 2010.Genes oxa-51 and oxa-23 were detected by PCR method,and the ST profiles were determined by multilocus sequence typing (MLST).The disk susceptibility assay was used to determine the inhibition zone diameters of β-lactams,aminoglycosides,macrolides,tetracyclines,carbapenems,tigecycline and polymyxin.The minimum inhibitory concentration (MIC) of tigecycline was determined by E-test in strains with inhibition zone diameters ≤ 12 mm on tigecycline.The expression of operon genes adeB,adeG and adeJ was determined with efflux pump inhibitor NMP (N-methyl-2-pyrrolidone) for detection of efflux pump inhibitor phenotype.The isolates of Acinetobacter baumanii which were resistant both to tigecycline and carbapenems and with the inhibited phenotype of efflux pump inhibitor were collected as the experiment group,the isolates which were susceptible to tigecycline but resistant to carbapenems were collected as the control group,and ATCC 19606 was used as the reference strain.The expressions of adeABC,adeFGH and adeIJK were quantified by q-PCR at the transcriptional level.Genes adeR,adeS and adeL were amplified and sequenced using PCR method to find polymorphic locus and insertion sequences.Results There were 32 isolates of Acinetobacter baumanii with reduced susceptibility to tigecycline and carbapenem-resistant.Eight isolates were with the inhibited phenotype by efflux pump inhibitor.And 4 strains which were susceptible to tigecycline but resistant to carbapenems were selected as the control.The expressions of adeABC in A518,Z1219 and A527 of experiment group were 13-fold,5-fold and 7-fold higher than reference strain ATCC19606,respectively.The expressions of adeFGH and adeIJK were up-regulated slightly in some isolates.Transcript of adeABC was not found in control group strains A207 and A1731,and the expressions of adeABC,adeFGH and adeIJK were not up-regulated in other isolates.The single nucleotide polymorphism (SNP) was detected in adeR (E220K) and adeS (A130D),respectively.ISAab1 insertion sequence was identified in adeS of adeABC-over expressed isolates.No mutation was found in adeL.Conclusion High expression of adeABC pump may play an important role in tigecycline resistance in carbapenem-resistant Acinetobacter baumannii,mainly due to the insertion of ISAba1 sequence in its regulator gene adeS,but other mechanism of tigecycline resistance may not be excluded.

Objective To investigate the clinical effect of early rehabilitation treatment on patients with severe traumatic brain injury (sTBI).Methods Forty sTBI patients were divided into treatment group (n =20) and control group (n =20) according to the random number table.Conventional treatment was performed on all patients including dehydration to decrease intracranial pressure,hemorrhage control,neurotrophic treatment,antiinflammation therapy,and gastric acid control.In addition to these interventions,patients in treatment group received hyperbaric oxygen treatment,median nerve stimulation,fastigial nucleus stimulation,and bedside motor therapy in the early period.Intracranial pressure and partial pressure of brain tissue oxygen (PbtO2) were continuously monitored during the process of treatment.GCS was measured before and 15 days after treatment and single-photon emission computed tomography (SPE-CT) was used to evaluate cerebral perfusion.Results There was no statistical difference between the two groups with respect to GCS in advance of treatment (P ＞ 0.05),but GCS differed between treatment group and control group after treatment [(10.18 ± 3.75) points vs (8.33 ±2.36) points,P ＜0.05],with substantial improvement in treatment group.Significantly improved cerebral perfusion was seen in treatment group.On day 5 after treatment,intracranial pressure in treatment group lowered significantly compared with that in control group (P ＜ 0.05).On day 6 after treatment,PbtO2 was significantly higher in treatment group than in control group (P ＜ 0.05).Conclusion Early rehabilitation treatment leads to improved outcome and acts a positive effect on nerve function recovery.
