Circulating endothelial cells(CEC)are mature endothelial cells,which have been shed from the vascular cell lining and enter into blood circulation.Rare in healthy individuals,increased CEC in peripheral blood reflects significant vascular damage and dysfunction.Increased CEC have been documented in many human diseases characterized as vascular damage,including different types of tumors.Clinical data suggest that CEC count is a promising tool for monitoring disease activity with potential to assess tumor prognosis and response to treatment.

Primary liver cancer is a common malignant tumor in the digestive system.Most patients are in the advanced stage when a con-firmed diagnosis has been made,and prognosis is often unfavorable.Traditional Chinese medicine (TCM)has unique advantages in the pre-vention and treatment of primary liver cancer.This article briefly introduces the etiology and pathogenesis of primary liver cancer,as well as syndrome differentiation and treatment of liver cancer with TCM,and summarizes the advances in multimodality therapies including TCM combined with transcatheter arterial chemoembolization,radical surgery for liver cancer,chemoradiotherapy,and molecular-targeted thera-py,in order to provide a reference for the clinical treatment and improvement in the prognosis of primary liver cancer.

AIM: To access the difference of the efficacy between terbinafine and itraconazole in the treatment of dermatophyte onychomycosis. METHODS: The Medline, Science Direct On Site (SDOS), and Springer database were searched in detail on the data of the mycological cure rates of the two antifungal agents for treatment of dermaphyte onychomycosis occourring in patients aged from 18 a to 60 a with the published double blind randomized clinical trials and then pooled. The odds ratio (OR) and its 95 % confidence interval (CI) were calculated. RESULTS: Six treatises of double blind randomized clinical trials were selected for this analysis according to the screening criteria. The mycological cure rate of continuous terbinafine 250 mg per day was higher than that of either therapeutic effect of itraconazole pulse 400 mg per day (OR = 5.01, 95 % CI (3.42 - 7.33)) or continuous itraconazole 200 mg per day (OR = 2.58, 95 % CI (1.91 - 3.49)) . CONCLUSION: Terbinafine is more effective than itraconazole in the treatment of dermatophyte onychomycosis.

Objective To survey the value of quantitative detection of urinary endotoxin for the diagnosis of gram-negative bacteria infection in urinary system,in order to provide evidences for early diagnosis and treatment.Methods The levels of urinary endotoxin were detected by kinetic turbidimetric technique,at the same time urine was cultured and WBC,CRP were detected.Results In 379 patients with gram-negative bacteria infection in urinary system,132 patients were upper urinary tract infection and 247 were lower urinary tract infection.The level of WBC,CRP and endotoxin were 11.25(7.98,13.99)× 109/L,81.36(76.64,83.50)mg/L and 49.57(17.28,78.37)pg/ml in upper urinary tract infection patients and in lower uri-nary tract infection patients were 10.24(7.94,12.24)×109/L,70.46(70.46,77.32)mg/L and 21.18(21.18,37.31)pg/ml. The group of upper urinary tract infection was higher than lower urinary tract infection on CRP and endotoxin,and have sig-nificant difference between the two groups of patients (P<0.05).Analysis of ROC,the diagnostic Cut-off value of 39.7pg/ml,the sensibility and specificity of endotoxin for the diagnosis of gram-negative bacteria infection on upper or lower urinary system were 84.1% and 90.3%.Conclusion The levels of urinary endotoxin detected by kinetic turbidimetric technique is simple and efficient,and have significant diagnosis value of gram-negative bacteria infection on upper or lower urinary sys-tem.

Objective To investigate the apoptosis response to mechanical stretch in human alveolar type Ⅱ epithelial cells A549.Methods First,A549 cells were given different stretch(0%,5%,15%,30%) at frequency of 0.5 Hz for 4 h.Then,A549 cells were stretched for different periods(0 h,2 h,4 h,8 h) at stretch 15%,0.5 Hz.Last,A549 cells were stretched for different frequency(0 Hz,0.2 Hz,0.5 Hz and 1 Hz) at stretch 15% for 4 h.The early apoptosis was detected by flow cytometry. Results A549 cells submitted to cyclic stretch caused the early apoptosis in a time-,stretch-and frequency-dependent manner.In details,at 0.5 Hz and 4 h stretch-dependence occurred,at 15% stretch and 0.5 Hz time-dependence occurred,and at 15% stretch and 4 h frequency-dependence occurred. Conclusion Mechanical stretch can induce the early apoptosis in human alveolar type Ⅱ epithelial cells A549,which may be one of the mechanisms of ventilator-induced lung injury.
