Objective To systematically review the literature evaluating efficacy and adverse events of propranolol for infantile hemangiomas (IHs).Methods We searched the Cochrane,Medline,Wiley,CNKI and Wanfang Databases for all studies on the response of IHs to propranolol only which were published between June 2008 and May 2013.Results A total of 23 studies were collected,including 14 case reports and 2 follow-up studies which were without random and control;another 6 studies were clinical controlled trials and 1 study was RCT.Total 716 patients were included,and never received other treatments before propranolol.Propranolol was initiated at a mean age of (4.5 ± 0.5)months at a mean dose of 2.1 mg/kg/day and for a mean treatment duration of (9.7±9.2) months.The effective rate for patients with IHs treated with propranolol was 97％ (691/716),and patients after treatment completion reported IHs recurred in 8.6 ％ of patients.The adverse effects rate was 31％(223/7167) which most common adverse events were changes in sleep (n=35),gastrointestinal reaction (n =52) and decreased heart rate (n =73),and 5 patients discontinued the treatment because of the serious adverse events.Conclusions This systematic review of 716 patients treated with propranolol for IHs show a high rate of efficacy and a low rate of serious adverse events,and it is a better treatment of infantile hemangioma,but we should pay more attention to the serious adverse events and strictly select indications.

Objective: To detect circulating tumor cells (CTCs) in patients with gastric cancer and evaluate the relationship among CTCs, clinico-pathological characteristics, and prognosis of gastric cancer. Methods: Peripheral blood samples (10 mL in EDTA) were obtained from 45 patients with gastric cancer. CTCs were detected using density-gradient centrifugation and immunofluo-rescence staining. The clinical significance of the two methods were also compared and investigated. Results:CTC-positive case was defined by the presence of at least one CK19 (+)-CTC per 10 mL of the sample. CTCs were found in 27 of the 45 patients with gastric cancer. The presence of CTCs was significantly correlated with lymph node metastasis, distant metastasis, and recurrence (P=0.007, 0.035, 0.035, respectively). However, CTCs were not significantly correlated with sex, age, tumor location, TNM staging, and tumor differentiation (P>0.05). Conclusion:CTCs were associated with poor prognosis of gastric cancer.

Objective To explore the expression and significance of CD44 gastric cancer stem cell biomarker positive circulating tumor cells (CTC ) in peripheral blood of patients with gastric cancer . Methods From March 2010 to December 2012 ,45 patients with gastric cancer and 20 healthy individuals were enrolled .Peripheral blood samples of all the subjects were collected .The expression of CTC and CD44 postive CTC were detected by density gradient centrifugation method and double immunofluorescent staining .Chi‐square test and t‐test were performed for statistical analysis .Results CTC in peripheral blood of healthy controls were not detected .Among 45 patients with gastric cancer ,CTC were detected in 27 patients and 19 of them were CD44‐positive .The difference in positive rate of CTC expression was statistically significant between two groups (χ2 =10 .986 , P<0 .05) .Among 27 CTC‐positive patients , 19 were proximal gastric cancer and 16 of them were CD44‐positive;16 patients had lymph node metastasis and 14 of them were CD44‐positive;13 patients had distant metastasis and 12 of them were CD44‐positive;14 patients had recurrence and 13 of them were CD44‐positive .The CD44 positive CTC was correlated with tumor location ,lymph node metastasis ,distant metastasis and recurrence (χ2=5 .891 ,5 .527 ,5 .787 and 7 .052 ,respectively ,all P<0 .05) .Furthermore ,in 13 patients with recurrence and CD44 positive CTC ,the recurrence time was (10 .54 ± 5 .55) months which was shorter than that of one patients with CD44 negative CTC (19 months) ,and the difference was statistically significant (t= -3 .654 , P=0 .004) .Conclusions CTC which express cancer stem cell marker may be associated with recurrence and metastasis of gastric cancer .It has more important clinical significance to detect this subtype of CTC .

Objective To explore the correlation between high-risk human papillomavirus(hr-HPV) viral load and severity of cervical lesion. Methods One thousand eight hundred and six women undergoing both hr-HPV DNA test by hybrid capture Ⅱ(HCⅡ) and colposcopic biopsy for histologic results were enrolled in this study.Correlation between hr-HPV viral load and pathological findings was investigated. Results Of 1 806 cases,641(35.5%) patients were positive for HPV DNA.23.2%(301/1299) of women with normal diagnosis had HPV infection,significantly lower than cervical lesion including cervical intraepithelial neoplasia(CIN) and cervical cancer(P=0.000).Associations(odds ratio) among severity of cervical lesion and viral load were calculated.The significantly increased risk only existed between cervical cancer and CIN1 on high viral load(odds ratio,8.5;95% confidence interval,1.0-71.4;P=0.049).Furthermore,viral load values in CIN1,2,3 and cervical cancer were calculated and median analysis revealed non-significant difference(P=0.712). Conclusion The hr-HPV viral load can distinguish cervical lesion as CIN and cervical cancer from normal one,while the prediction of the severity of cervical lesion may be inadequate and need further investigations.

Objective To observe the effect of autophagy inhibitor on the activation of alcohol induced hepatic stel-late cells, and the mechanisms thereof. Methods HSC-T6 cells were cultured in vitro and divided into four groups, includ-ing blank control group, alcohol group, 5 mmol/L 3-MA+alcohol group (low alcohol group) and 10 mmol/L 3-MA+alcohol group (high alcohol group). RT-PCR was used to detect the expression levels ofα-smooth muscle actin (α-SMA) and typeⅠcollagen. The levels of LC3Ⅱ,α-SMA and typeⅠcollagen were detected by Western blot assay. The cell viability of HSC-T6 was detected by MTT assay. Results The mRNA expressions ofα-SMA, typeⅠcollagen and the protein of expressionsα-SMA, typeⅠcollagen and LC3Ⅱwere significantly up-regulated in alcohol group compared with those of control group (P<0.05), while the expressions of those parameters were significantly down-regulated in 10 mmol/L 3-MA+alcohol group (P<0.01). The mRNA and protein levels ofα-SMA and typeⅠcollagen were significantly decreased in two 3-MA-treated groups compared with those in alcohol group (P<0.05). Meanwhile, compared with the 5 mmol/L 3-MA+alcohol group,the protein expressions ofα-SMA, typeⅠcollagen and LC3Ⅱwere significantly decreased in10 mmol/L 3-MA+alcohol group (P < 0.05 ). Compared with the alcohol group,there was significantly lower proliferation activity in all two 3-MA-treated groups (P<0.05). Conclusion 3-MA can inhibit the protein expression of LC3Ⅱ,α-SMA and typeⅠcollagen induced by alcohol in HSC-T6 cells, and inhibit the proliferation of HSC cells.
