For interventional therapy of hepatic carcinoma, the anatomical pathway and the variation of complex vessels often cause difficulties in performing super-selective catheterization, or even result in catheterization failure. Understanding of the vascular variations and finding out the effective technique of catheterization can surely reduce the radiation exposure dose to both the operators and patients, and in the same time, can increase the successful rate of super-selective catheterization, which will undoubtedly improve the curative effect. More than 30 thousand times of interventional managements for hepatic carcinoma have been performed in our hospital, from which the author has selected some successful cases as well as some unsuccessful cases to make a technical analysis in order to sum up the experience of super-selective catheterization for clinical physicians' reference.

Interventional treatment has become the first-line therapeutic method for intermediate-stage hepatocellular carcinoma (HCC). With the development of related techniques,drug-loaded microparticles and radioactive microspheres have been applied in clinical prac-tice,with good therapeutic effect achieved.This paper analyzes and summarizes the existing interventional treatment methods and problems, and points out that HCC patients can achieve great benefits from combination therapy,and that standardized interventional therapy is a direc-tion for future development.

Objective To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) with 355～500?m polyvinyl alcohol (PVA) particles for treatment of larger hepatocellular carcinoma (HCC). Methods Seventy-three patients with larger HCC had been undergone TACE. Median tumor size was 12.3 (range 8.4～20.4) cm with Child-Pugh class A in all patients. The chemotherapy agents, Lipiodol and PVA were injected into tumor artery for each patient, with dose of PVA 100mg for 71 patients, 200mg and 50mg for each of another cases, respectively. The changes and responses of liver function and tumor size were noted. Results The tumor size decreased with an average of 3cm (P

Seven cases exhibited segmental bile duct dilation with filling defects. One case only showed dilatation of lobar bile ducts. Conclusion MRI features of IPNB are helpful for distinguishing IPNB from other hepatic lesions.

Objective To evaluate the value of liver acquisition with volume acceleration(LAVA) in the diagnosis of hepatic outflow abnormalities.Methods LAVA was performed in 78 patients with suspected hepatic outflow abnormalities,thrombosis,stenosis,occlusion,or compression,including 71 hepatocellular carcinomas and 7 Budd-Chiari syndrome.Image quality and the presence of venous abnormalities and collaterals were evaluated.Results LAVA images were of diagnostic quality and without artifact in all patients.LAVA clearly showed the vascular anatomy and various disorders.The site,extent,cause of venous obstruction,and collateral pathways were well depicted.Conclusion LAVA is simple to perform and accurate in detecting hepatic outflow abnormalities.

10 mm)were showed by DSA.On nonenhanced CT,there were 3-4 low density nodules and 4 isodensity nodules.Thirty-two nodules was high density and 8 nodules was low density in arterial phase,33 and 7 nodules were low density and isodensity respectively in portal venous phase,39 and 1 nodule were low density and isodensity respectively in delayed phase.Conclusion The MSCT is excelled DSA in detection satellite nodule of HCC,especially smaller than 10 mm nodule.

Hepatocellular carcinoma (HCC) has a high fatality rate and most patients are in advanced stage when diagnosed with routine methods.As a molecular imaging method, positron emission tomography/computed tomography (PET/CT) has become more and more important.However, it also has certain limitations, since it always has false-negative results for well-differentiated HCC and small HCC.Therefore, a combination of various tracers can improve the sensitivity and specificity of PET/CT in the diagnosis of HCC.This article reviews the role of PET/CT in the therapeutic effect evaluation, recurrence monitoring, and prognosis of HCC.

Objective To assess the quality of examination paper,level of examination paper proposition,teachers' teaching quality and teaching effect by sampling inspection of examination paper.Methods Examination papers of 85 courses were quantitatively assessed by using evaluation form of Examination Paper Quality of Anhui Medical University.Results Propositions of papers were well or largely complied with the requirements of syllabus.2.4％ of examination papers had content errors.Students' scores of 91.6％ papers were in normal distribution.Quality of papers was improved year by year,but was significantly different among public basic courses,specialized basic courses and specialized courses(x2 =8.865,P =0.042).The qualitative analysis results showed that there were shortcomings in proposition,grading,paper analysis and archiving.Conclusions Management of examination paper is needed to improve the quality of teaching and studying and pave the way for the undergraduate teaching evaluation.

Objective To improve health care workers’(HCWs)infection prevention and control consciousness through carrying out catheter-associated urinary tract infection(CAUTI)prevention and control project,and imple-ment prevention and control measures in practical work.Methods Diagnostic criteria of CAUTI issued by the U.S. Centers for Disease Prevention and Control/National Healthcare Safety Network were adopted,from October 2013 to September 2014,monitoring was conducted on CAUTI in patients with indwelling urinary catheters for >2 con-secutive days at different types of ICUs in hospitals participated in the project .Results A total of 14 124 CAUTI cases were collected,410 patients developed CAUTI,urinary catheter usage rate was 79.33%(203 114/256 042), incidence of CAUTI was 2.02‰(410/203 114),urine specimen detection rate was 46.52%(6 570 /14 124).The detection rate of urine specimens increased from 37.24% (the fourth quarter of 2013)to 49.76% (the third quarter of 2014).Of prevention measures,the difference in the indication of catheterization was significantly different(P <0.01).Conclusion Through the development of competence building project of healthcare-associated infection pre-vention and control,prevention and control of CAUTI has achieved good intervention effect.

OBJECTIVE:To observe clinical efficacy and safety of Chaihu shugan powder combined with clonazepam in the treatment of liver qi stagnation type anxiety. METHODS:96 patients with liver qi stagnation type anxiety were randomly divided in-to observation group and control group,with 48 cases in each group. Control group was given Clonazepam tablet with initial dose of 0.5 mg,increasing to 4.0 mg gradually,tid;observation group was additionally given Chaihu shugan powder 300 ml,bid,on the basis of control group. Both groups were treated for 6 weeks. Clinical efficacy of 2 groups were observed,and HAMA and SAS were observed before and after treatment;the incidence of ADR were compared between 2 groups. RESULTS:The total effective rate of observation group(97.92%)was significantly higher than that of control group(83.33%),with statistical significance(P<0.05). There was no statistical significance in HAMA and SAS between 2 groups before treatment(P>0.05);HAMA and SAS of 2 groups decreased significantly 1,3 and 6 weeks after treatment,and the observation group was lower than the control group, with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Chaihu shugan powder combined with clonazepam is effective,improve patient anxiety and safe in the treatment of liver qi stagnation type anxiety.
