Objective To evaluate the value of whole body 18F-FDG PET/CT in the detection of recurrence/metastasis of cervical cancer.Methods A retrospective study was performed on 95 patients with cervical cancer who underwent 18F-FDG PET/CT after treatment.The lesion characteristics on 18F-FDG PET/CT were assessed visually and semi-quantitatively.A final diagnosis was confirmed by histopathology,diagnostic treatment and clinical follow-up imaging.The data were analyzed by Kappa test.Results 18 F-FDG PET/CT was positive in 54 patients,including 24 with local recurrence and 30 with distant metastases.The sensitivity,specificity and accuracy of 18F-FDG PET/CT for the detection of recurrence/metastasis of cervical cancer were 98.1％ (52/53),95.2％ (40/42) and 96.8％ (92/95),respectively.The positive predictive and negative predictive value were 96.3％ (52/54) and 97.6％ (40/41),respectively.18F-FDG PET/CT showed concordant results with pathological/clinical follow-up findings (Kappa =0.936,P＜0.05).Conclusion 18F-FDG PET/CT is a sensitive and specific modality for the detection of recurrence/metastasis of cervical cancer and might be useful for further treatment plan.

Objective To explore the therapeutic effects and dose of Topiramate(TPM)in children with Tourette syndrome(TS).Me-thods Seventy-nine children with TS were given oral TPM,which were treated with Topiramate [0.5-3.0 mg/(kg?d),twice a day].The therapeutic effects were assessed using Yale Global Tic Severity Scale(YGTSS)before and 3 months after treatment and the side-effects of the drugs were observed.Results The differences of YGTSS scores before and after treatment,motertic score(19.63?3.09 vs 5.05?1.74),vocaltic score[(18.95?2.56)vs(4.82?1.94)],global scole score[(24.21?5.89)vs(10.42?3.69)],severity score[(62.21?5.81)vs(22.26?4.81)],there were significant differences of every score of YGTSS between before and after treatment(Pa

Objective In our previous study, we had generated various zebrafish mutant lines with tissue?specific GFP expression by Tol2 transposon?mediated insertional mutagenesis. Among these mutants,the Tol2:20141221t line ex?presses GFP in nervous system, while the position within zebrafish genome where transposon inserted has not yet been iden?tified. The aim of this study was to identify and analyze this genetically modified mutant. Methods The transgenic inser?tion loci in the genome of Tol2:20141221t line was identified byTAIL?PCR and the spatial and temporal expression profile of the affected gene was examined by in situ hybridization. Homozygous mutant of Tol2:20141221t was generated for explo?ring related developmental defects. Results Tol2 transposon was inserted into the 8th intron region of sat1.a gene, and in?duced premature transcription termination. The maternal and zygotic mutants of Tol2:20141221t was generated, while with?out apparent developmental defects. Conclusions We have generated and identified the zebrafishsat1.a mutant mediated by Tol2 transposon. This gene insertion mutant exhibits no obvious developmental abnormalities, but may serve as a power?ful tool to study the development of nervous system.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

Duck circovirus(DuCV),a potential immunosuppressive virus,was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction(PCR)based method. In this study,a total of 138 sick or dead duck samples from 18 different farms were examined with an average DuCV infection rate of～35%. It was found that ducks between the ages of 40～60 days were more susceptible to DuCV. There was no evidence showing that the DuCV virus was capable of vertical transmission. Farms with positive PCR results exhibited no regularly apparent clinical abnormalities such as feathering disorders,growth retardation or lower-than-average weight. The complete genomes of 9. strains from Fujian Province and 1 from Zhejiang Province were sequenced and analyzed. The 10 DuCV genomes,compared with others genomes downloaded from GenBank,ranged in size from 1988 to 1996 base pairs,with sequence identities ranging from 83.2% to 99.8%. Phylogenetic analysis based on genome sequences demonstrated that DuCVs can be divided into two distinct genetic genotypes,Group I(the Euro-USA lineage)and Group II(the Taiwan lineage),with approximately 10.0% genetic difference between the two types. Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species,including Duck,Muscovy duck,Mule duck,Cheery duck,Mulard duck and Pekin duck.

ObjectiveTo investigate the clinical outcome of laparoscopic nephroureterectomy (LUNT) for native upper tract urothelial carcinoma (UC) in renal transplant (RT) recipients.Methods We conducted a retrospective analysis on 1130 RT recipients,and 9 patients (0.8％,9/1130) with native upper tract UC were identified. UC was confirmed pathologically in the 9 patients,including 3 cases of unilateral ureter tumor (2 on the right,and 1 on the left),4 cases of unilateral renal pelvis tumor (2 on the right,2 on the left),1 case of bilateral ureter tumor and 1 case of tumor in the right ureter and left kidney.Females predominated (8/9) in the 9 patients with upper tract UC.The patients with left upper urinary tract cancer underwent LUNT using a retroperitoneal approach with a technique of transurethral circumcision of the ureteral orifice.The patients with right upper urinary tract cancer were subjected to nephroureterctomy with ureterectomy and bladder cuff excision by complete laparascopy through a transperitoneal approach. Immunosuppressive protocol conversion from calcineurin inhibitors to sirolimus was performed on all cases. Results In the 9 patients,11 LUNTs were performed successfully without conversion to open surgery.The follow-up period was from 6 to 48 months. One patient died of lung metastasis at 8th month after tumor excision,and 1 patient displayed ductal cancer of the left breast at 7th month after LNUT.Another seven patients showed no evidence of disease during the follow-up period with normal renal function.ConclusionOur present clinical experience suggested that LNUT for the native upper tract cancer in renal transplant recipients is feasible,safe,and effective.
