Objective To observe the effect of ligustrazine injection combined with chemotherapy on common immunological parameters in patients with advanced hepatocellular carcinoma.Methods Eighty cases diagnosed with advanced hepatocellular carcinoma from January 2013 to January 2015 in the hospital were randomly divided into observation group and control group, 40 patients in each group.The control group received only conventional treatment of chemotherapy and observation group received ligustrazine injection on the basis of control group.The levels of interleukin-1 (IL-1), IL-4 and transforming growth factor beta ( TGF-β) wwere compared based on the record between two groups pre-and post-treatment.Results There were no significant differences between two groups in IL-1,IL-4 and TGF-βlevels pre-treatment.After treatment, the IL-1, IL-4 and TGF-βlevels in observation group were lower than those in control group [(41.4 ±11.8)vs (76.0 ±12.2)ng/L,(118.5 ±39.9)vs(223.0 ±47.3)ng/L,(6.7 ±3.2)vs(11.7 ± 2.6)ng/mL, respectively, all P<0.05].Conclusion Ligustrazine injection combined with chemotherapy has an exact effect on improving the immunological parameters associated with advanced hepatocellular carcinoma without significantly increasing side effects, it is worthy of further research and application.

ObjectiveTo evaluate and compare the curative effect and the safety of sclerotherapy of venous malformation in children using absolute ethanol and pingyangmycin.MethodsEighty children with venous malformation were treated by sclerotherapy with absolute ethanol or pingyangmycin under general anesthesia during February of 2009 to May of 2011. Diagnostic criteria included the presence of a bluecolored lesion at birth,with gradual increase in its size associated with a positive postural test.MRI showed characteristic imaging features.Eighty patients were divided into two groups by randomization.Forty patients were treated with absolute ethanol,and the remaining 40 patients with pingyangmycin. The therapeutic effects and side effects were observed and recorded during a follow-up period of 6 to 24 months ( average 15 months).Treatment results weredividedinto four categories: cure, basiccure, effective, and ineffective,and the former three categories were considered effective in treatment.Chi-square test was used to compare the rate of effective treatment and rate of complications in these two groups.ResultsThe effective patients treated with absolute ethanol was 38 (95.0％,38/40),and the effective patients with pingyangmycin was 26(65.0％,26/40),x2 test ( x2 =11.25,P ＜ 0.01 ) difference was statistically significant.Eight patients developed skin necrosis; 4 patients serious local swelling,2 patients muscle fibrosis,1 patient cerebral embolism in the absolute alcohol group.Two patients developed postoperative fever and vomiting and 2 skin necrosis in the pingyangmycin group,the difference was statistically significant (x2 =12.29,P ＜0.01 ). ConclusionsSclerotherapyiseffectiveforthetreatmentofvenousmalformationsin children.Absolute ethanol is more effective,but associated with more complications,such as skin necrosis or as serious as cerebral embolism,than pingyangmycin.

Objective To identify the sequence of hepatitis B virus S gene"a"determinant in patients with positive HBsAg and anti-HBs.Methods Nested-PCR Was used to amplify the HBV S gene in 4 patients with positive HBsAg and anti-HBs,and the PCR products were sequenced directly or after cloning.The sequences of"a" determinants were then analyzed by sequence alignment.Results Direct sequencing of PCR products showed that there was one amino acid (aa)residue in"a"determinant less conserved region emerging polymorphism in all 4 patients.Clone sequencing showed that aa residue at 126 of "a"determinant in patient 1 miSht be Thr,Ile and Set,at 134 might be Phe and Set;the aa at 126 in patient 2 misht be Ala and Thr.and in patient 3 might be Ile and Asn;aa polymorphism was not found in patient 4.Conclusion The polymorphism of"a"determinant in HBV S gene might be associated with positivity of both HBsAg and anti-HBs in hepatitis B patients.

Objective To explore the effect and safty of interventional embolization of congenital arteriovenous fistula (CAVF) in the common femoral profounda artery in children.Methods Eight children (aged 6 to 14 years ;6 males and 2 females) with CAVF underwent interventional embolization From January 2006 and December 2010.Color Doppler sonography and DSA were performed on all patients.Arterial duplex imaging revealed the arteriovenous fistula in the common femoral profounda artery and DSA further confirmed the presence of an AVF over the common femoral profounda artery via the other vein.All children were treated with interventional embolization therapy by the injection ofcoils or ethanol through a microcather.It was necessary to performed repeated interventional embolization if the lesion was not obliterated in 4 weeks.All patients were followed-up from 6 months to 2 years and the clinical symptoms were observed.Results Arteriograpy can clearly demonstrate the femoral profounda artery and its branches as well as the fistula.Ten interventional embolization procedures were performed.Forty seven coils were deployedduring the procedure and seven ethanol embolization procedures were performed.Post-procedural angiography revealed complete occlusion in 8 patients.No major complications such as ectopic coil embolization,tissue necrosis,peripheral nerve palsy or cardio-pulmonary collapse were found.The abnormal AVFs were embolized completely in 7 cases after only one therapy and there was no recurrent disease in the 6 months to 2 years follow-up.Some tiny AVFs were still found in another case which underwent three additional treatments.However,the clinical symptoms were under control.Conclusion Interventional embolization is a safe and effective therapeutic method for CAVF of the common femoral profounda artery in children and it might become the primary treatment option.

BACKGROUND:Hypertrophic differentiation of chondrocytes is the sign of starting endochondral ossification, and it is also an essential step in endochondral ossification, which is a cascade reaction and difficult to be blocked once started. The end result is the formation of bone structure. RNA interference is a post-transcriptional gene silencing. Relevant studies have shown that the use of RNA interference to block the expression of core binding factorα1 (Cbfα1) can effectively inhibit the formation of heterotopic ossification. OBJECTIVE:To use RNA intereference technology to suppress Cbfα1 expression so as to achieve the purpose of blocking the hypertrophic diferentiation of chondrocytes. METHODs: We constructed an adenovirus containing siRNA against Cbfα1 (Ad-Cbfα1-siRNA). Retinoic acid and interleukin-1α were used to induce hypertrophic differetiation of chondrocytes, and then Ad-Cbfα1-siRNA was utilized to inhibit the hypertrophic differentiation of chondrocytes. Immunohistochemistry method was used to analyze the expression of Cbfα1. RESULTS AND CONCLUSION:After induction with retinoic acid and interleukin-1α, the chondrocytes in the negative control virus group appeared to have hypertrophy and the expression of Cbfα1 was positive. In the Ad-Cbα1-siRNA group, the expression of Cbfα1 was negative. These findings suggest that the inhibition of Cbfα1 by RNA interference can be a powerful way to prevent the hypertrophic differentiation of chondrocytes .

Objective To evaluate the efficacy and safety of interventional sclerotherapy for intraorbital venous malformation in children. Methods A retrospective analysis of 12 cases with intraorbital venous malformation from March 2007 to July 2013 in our department was made. Twelve lesions including 7 in left eyes and 5 in right eyes were evaluated. Three patients had surgical resection before interventional treatment. Sclerosing agent such as sclerosant foam or pingyangmycin was injected into the lesions guided by DSA. Interventional sclerotherapy was performed once every month until no blood return was observed. Then MRI was used to detect the lesions 1 month after operation. If there were residual lesions in MRI images, then repeat treatment was performed. Postoperative observation included patients' general situation and adverse reactions of eye after each treatment. Results Interventional sclerotherapy were performed to all patients for a total of 42 times (mean time 3.5 ± 1.0 per patient). After a follow?up of 24months, 7 cases were cured, 3 cases improved significantly and 2 cases with partial remission. Postoperative adverse reactions: transient exophthalmos in 39 case?times , peri?orbital and maxillofacial tissue swelling in 32 case?times. No severe complications were observed. Conclusion Interventional sclerotherapy is an easy, safe and effective method for treatment of intraorbital venous malformation.

Purpose: This study aimed to identify the risk factors and sonographic variables that could be integrated into a predictive model for endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) in women with abnormal uterine bleeding (AUB). Materials and Methods: This retrospective study included 1837 patients who presented with AUB and underwent endometrial sampling. Multivariable logistic regression was developed based on clinical and sonographic covariates [endometrial thickness (ET), resistance index (RI) of the endometrial vasculature] assessed for their association with EC/AEH in the development group (n=1369), and a predictive nomogram was proposed. The model was validated in 468 patients. Results: Histological examination revealed 167 patients (12.2%) with EC or AEH in the development group. Using multivariable logistic regression, the following variables were incorporated in the prediction of endometrial malignancy: metabolic diseases [odds ratio (OR)=7.764, 95% confidence intervals (CI) 5.042–11.955], family history (OR=3.555, 95% CI 1.055–11.971), age ≥40 years (OR=3.195, 95% CI 1.878–5.435), RI ≤0.5 (OR=8.733, 95% CI 4.311–17.692), and ET ≥10 mm (OR=8.479, 95% CI 5.440–13.216). :A nomogram was created using these five variables with an area under the curve of 0.837 (95% CI 0.800–0.874). The calibration curve showed good agreement between the observed and predicted occurrences. For the validation group, the model provided acceptable discrimination and calibration. Conclusion The proposed nomogram model showed moderate prediction accuracy in the differentiation between benign and malignant endometrial lesions among women with AUB.
