Objective To evaluate the efficacy and safety of 650 nm,810 nm diode laser on the treatment of moderate to severe acne.Methods A total of 87 patients with moderate to severe acne were divided into diode laser group (group A) and medication group (group B).In group A,the patients were irradiated with 650,810 nm diode laser at the fluence of 400-450 mW distance of 2-3 cm.In group B,the patients were treated with roxithromycin combined with vitamin B6 and gel lincomycini.Clinical follow-up was performed every week for 4 months.All the adverse effects were recorded.Results There was no significantly statistical difference in the cure rate between the two groups (group A versus group B at 2 weeks:65.0 % versus 42.6 %,P>0.05; at 4 weeks:92.5 % versus 76.5 %,P>0.05).However,the recurrence rate of group A was much lower than that of group B (30.0 % versus 61.7 %,P<0.01).There were no severe adverse effects in both groups during the period of the follow-up.Conclusions Compared to the medication,650,810 nm diode laser appears to be associated with lower recurrence rate in the treatment of moderate to severe acne.

Background and purpose:Hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare, vascularly original tumor, and would be misdiagnosed easily in the clinical and imaging characteristics. This study aimed to investigate the imaging features of HEHE and our experience in clinical diagnosis and treatment, and to provide important reference for the diagnosis and treatment of HEHE in the future.Methods:This study retrospectively analyzed clinical manifestations, imaging features, pathological characteristics and treatment effects of 5 HEHE cases confirmed by pathology at Department of Integrative Cancer, Fudan University Shanghai Cancer Center.Results:The ratio of male to female patients was 2 to 3. HEHE predominantly occurred in middle-aged female patients whose ages range from 26 to 65 (mean=45.6). Imaging features of HEHE included multifocal hepatic disease (n=2), systemic multi-center multi-tissue occurrence (n=3). The ultrasound images showed isoechoic or hypoechoic lesions with no obvious blood lfow signal in the lesions. CT plain scan showed isointensity or hypointensity, while MR unenhanced with hypointense T1 signal and hyperintense T2 signal. The density or signal was uneven. Contrast-enhanced CT and MR images showed “slow in slow out”, obvious and variable degrees of peripheral rim enhancement. High FDG uptake showed delayed imaging characteristics (PET/CT). DSA angiography showed the tumor blood vessels were slim. After transcatheter arterial chemoembolization (TACE) surgery, lipiodol deposition within the lesion was not ideal. Under the microscope, tumor cells showed epithelial differentiation; angiogenesis was also visible. Immunohistochemistry staining showed CD31 and CD34 positive in all the 5 cases. Two cases treated with TACE combined with high intensity focused ultrasound (HIFU) and/or radiofrequency ablation (RFA) had good result.Conclusion:The clinical and radio-logical characteristics of HEHE are distinctive. Currently, for patients with systemic multi-organizational multi-center lesions, TACE combined with HIFU and/or RFA might be the most effective treatment method.

ObjectiveTo evaluate the efficacy and safety profiles of enteeavir (ETV) in patients with advanced schistosomiasis and hepatitis B virus (HBV) co-infection.Methods Totally sixty patients with advanced schistosomiasis and HBV co-infection were enrolled in this study.The patients were divided into ETV treatment group (n=30) and rhubarb treatment group who refused to receive antiviral treatment (n=30).The patients were treated with ETV or rhubarb thelepus ball on the basis of routine supportive therapy for 52 weeks.The hepatic fibrosis markers (e.g.hyaluronic acid,type Ⅲ procollagen,type Ⅳ collagen,laminin and fibronectin),alanine transaminase (ALT),HBV DNA,Child-Pugh score between two groups were compared.Intention to treat (ITT) population was used for analysis.The measurement data and the enumeration data were analyzed by t test and x2 test,respectively.ResultsAfter 52-week treatment,the hepatic fibrosis markers (hyaluronic acid,type Ⅲ procollagen,type Ⅳ collagen,laminin and fibronectin) were significantly improved in ETV treatment group compared to the rhubarb treatment group (t =3.952,3.765,3.857,3.122 and 3.735,respectively; all P<0.05),and the fibrosis of liver tissue in ETV treatment group was significantly improved compared with rhubarb treatment group (x2 =11.207,P<0.05).The ALT level,HBV DNA,Child-Pugh score after 52-weeks treatment in ETV treatment group were statistically reduced compared with rhubarb treatment group (t =3.287,4.382 and 3.872,respectively; all P<0.05),meanwhile,the ALT normalization rate and HBV DNA undetectable rate were significantly increased in ETV treatment group (x2 =17.376 and 39.095,respectively; both P<0.05).In addition,no obvious adverse reaction was observed during ETV treatment.Conclusion Entecavir is safe and effective in patients with advanced schistosomiasis and HBV co-infection.
