Objective To investigate the feasibility,curative effect and problems of combined ultrasound-guided percutaneous radiofrequency ablation and ethanol injection(PRFA+EI) on small liver cancer located in first porta hepatis.Methods Twenty-six patients,who diagnosed as primary and metastatic liver cancer that located in first porta hepatis and was less than 5 cm in diameter by clinical evidence or pathology,were performed PRFA+EI between Jan 2001 and Oct 2004.The necrosis of the tumors was determined by MRI,Doppler ultrasound or CT after the treatment for one month and the regular examinations were tested every 3 months.The primary tumor recurrence rate and cumulative survival rate were calculated.Results The seroconversion rate of AFP was 76.9%(10/13).The complete necrosis rate of liver cancer in first porta hepatis was 84.6%(22/26) by MRI and CT.The primary tumor recurrence rate of 6 months and 1 year were 23.1%(6/26) and 26.9%(7/26),respectively.The 1-,2-,3-year cumulative survival rate were 92.3%(24/26),82.3% (14/17),75.0%(9/12),respectively.There was no occurrence of bile ducts stenosis.Conclusion The small live cancer located in first porta hepatis is not the contraindication of PRFA+EI.If the puncture point and route is selected properly,electrodes deployed exactly using ultrasound guidance and the size of heating area controlled appropriately,the PRFA+EI is an effective treatment for small liver cancer located in first porta hepatis.

Objective To analyze the clinical features and risk factors of invasive fungal infections (IFI) in children with acute leukemia.Methods Ninety-six acute leukemia children complicated with IFI admitted in Guangzhou Women and Children's Medical Center during January 2005 and February 2017 were retrospectively reviewed, and 96 cases of acute leukemia without IFI admitted at the same period were randomly selected as control group.The clinical manifestations of IFI were analyzed, multivariate Logistic regression was used to study risk factors of the complication of IFI in pediatric acute leukemia.Results Among 96 children complicated with IFI, fungus were detected in samples from sputum, bronchoalveolar lavage fluid, or blood in 78 cases, in which 42 cases (43.75％) were oral infection, 36 cases (37.50％) were pulmonary infection.Candida albicans (33.33％, 26/78) was the most commonly isolated pathogen, followed by Candida parapsilosis (20.51％, 16/78) and Candida tropicalis (20.51％, 16/78).Univariate analysis revealed hormone-containing chemotherapy, neutropenia (＜ 0.5 × 109/L), time duration of neutropenia ≥ 10 days, usage of carbapenem antibiotics and combined drug administration ≥2 types were associated with fungal infection (P ＜ 0.05 or ＜0.01).Multivariate Logistic regression showed that the time duration of neutropenia ≥ 10 days (OR =11.390, 95％ CI 4.145-55.263, P ＜ 0.01),usage of carbapenem antibiotics (OR =4.825, 95％ CI 1.681-13.842, P ＜ 0.01) and hormone-containing chemotherapy (OR =2.220, 95％ CI 1.542-8.246, P ＜ 0.05) were the independent risk factors of IFI.Conclusion Rational usage of antibiotics and effective measures taken to restore the granulocytes can help to reduce the incidence of IFI in children with acute leukemia.

Objectives To investigate the clinical characteristics and prognosis of late-onset group B streptococcal (GBS) sepsis. Methods From Jan. 2007 to Dec. 2011, iffteen neonates diagnosed with late onset GBS sepsis at discharge from NICU were retrospectively analyzed, meanwhile, thirty-four neonates diagnosed with late onset non-GBS Gram-positive bacteria sepsis at discharge were selected as controls during the same period. Results There were signiifcant differences in occurrence rates of shortness of breath, convulsion and apnea between late onset non-GBS sepsis group and late onset GBS sepsis group (P<0.05). The percentages of neonates with white blood cell count (CSF)>100×106/L, high-sensitivity C-reaction protein (hsCRP)>100 mg/L and glucose in CSF<3.11 mmol/L in late onset GBS sepsis group were higher than those in late onset non-GBS sepsis group (P<0.05). GBS was sensitive to penicillin, ampicillin, ceftriaxone, piperacillin/tazobactam, levolfoxacin and vancomycin. The rates of GBS resistance to erythromycin and gentamycin were both 87.5%. There were signiifcant differences in occurrence rates of meningitis, hydrocephalus and ependymitis between late onset GBS sepsis group and late onset non-GBS sepsis group (P<0.05), while no difference in mortality was found between two groups (P>0.05). Conclusions The late onset GBS sepsis is in-sidious, atypical, with many complications and sequelae. It is important for the suspicious neonates to use effective antibiotics as early as possible.
