Objective To explore the clinical efficacy and adverse reactions of transarterial chemoembolization(TACE)combined with sorafenib for the treatment of liver carcinoma.Methods Forty-eight cases of intermediate-advanced liver carcinoma patients were divided into TACE combined with sorafenib group(test group)and TACE only group(control group)according to the wishes of the patient,with 24 patients in each group.The median Survival Time(mOS),clinical efficacy,quality of life,liver function indexes and adverse reactions were compared in two groups.Results Until the deadline of follow-up time,the mOS in test group(15.9 months)was significantly higher than that in control group(9.3 months).The difference was statistically significant(P<0.05).The ORR,CBR in test group(58.3%,87.5%)were significantly higher than those in control group(33.3%, 54.2%).The difference was statistically significant(P<0.05).The quality of life improvement rate in test group(79.2%)was significantly higher than that in control group(37.5%).The differences were statistically significant (P<0.05 ).The ALB,TBIL increased significantly after treatment than before treatment in both groups.The differences were statistically significant(P<0.05 ).Conclusion TACE combined with sorafenib is more efficiency than TACE only treatment,and it could effectively extend the period of life to guarantee the quality of life.What's more,it has well tolerated adverse reactions,which is worthy of promoting.

Objective To evaluate the effects of laparoscopic filling with pedicled greater retina for hepatic cysts. Methods Clinical data were reviewed on 36 patients with hepatic cysts undergoing laparoscopic filling with pedicled greater retina from January 2010 to May 2014.The diameters of cysts ranged from 10 to 26 cm, with a diameter smaller than 20 cm in 29 patients and bigger than 20 cm in 7 patients.Laparoscopic fenestration of hepatic cysts was performed to destroy cyst cells with iodine and absolute alcohol. Pedicled greater retina was used for filling the cavity of cysts. Results The procedures were completed smoothly.The operative time was 45-115 min, with an average of (80.4 ±13.1) min.No abdominal cavity infection happened.Primary healing of abdominal incision was achieved in all the patients.The postoperative hospital stay was 5-10 d, with an average of (6.4 ±1.2) d.All the 36 patients were followed up for 6-12 months with a mean of (9.3 ±1.5) months.None of the patients showed recurrence under liver B-ultrasonography or CT scanning. Conclusion Laparoscopic filling with pedicled greater retina for hepatic cysts has advantages of minimal invasion, quick postoperative recovery, short hospital stay, and good results.

Objective To investigate the pathogens and their antibiotic resistance profile of hospital and community-acquired spontaneous bacterial peritonitis ( SBP) in patients with liver cirrhosis. Methods Eighty-four cirrhotic patients with SBP were recruited, in which 61 (72. 6% ) were diagnosed as communityacquired SBP and 23 (27.4% ) were diagnosed as hospital-acquired SBP. Bacterial identification and drug susceptibility tests were performed. SPSS 16. 0 was used for statistical analysis. Results There were 68 (81.0%) Gram-negative strains and 16 (19.0%) Gram-positive strains. Escherichia coli and Klebsiella pneumoniae were the top two prevalent strains. In community-acquired group, there were 21 (21/61, 34. 4% ) strains of Escherichia coli and 15 ( 15/61 , 24. 6% ) strains of Klebsiella pneumoniae; while in hospital-acquired group, it was 12 (12/23, 52.2%) strains and 6 (6/23, 26. 1%) strains, respectively. There were no statistical differences in the infection rates of Escherichia coli and Klebsiella pneumoniae between community and hospital-acquired SBP patients (x2 = 2. 21 and 0. 02, P > 0. 05). Drug susceptibility tests showed that Escherichia coli and Klebsiella pneumoniae were 100% sensitive to impenem, and the sensitivity to Piperacillin/Tazobactam was also high. But these strains were highly resistant to Ampicillin and Ampicillin/Sulbactam. All extended spectrum β-lactamases ( ESBLs) positive strains were resistant to cephalosporins, while ESBLs-negative strains were all sensitive to cephalosporins. Conclusions SBP in patients with liver cirrhosis are mainly caused by Gram-negative strains, especially Escherichia coli and Klebsiella pneumoniae. ESBLs-positive strains are highly resistant to cephalosporins, so proper use of right antibacterial agents is important.

The method of under--water weighing was used to measure the body composition of seventeen rhythmicgymnasts and four ordinary women. The average fat percentage was found to be 19. 0% in the gymoasts and26. 4% in the non--gytnnasts. The fat oercentage in the body composition of an athlete is not directly proportional to her body weight.It is inversely proportional to her training level. Therefore, in evaluating the physical condition of an athlete,her fat percentage must be taken into account. An artistic gymnast who is reducing bodyweight shows a negative energy belance of 50. 5% and insuffi-cient intake of protein and vitamins. Reduction of bodyweight should therefore be carried out under medicalsupervision.

Objective To investigate the clinical value of serum apolipoprotein A-1 (Apo A-1) detection in HBV-related liver cancer.Methods Totally 362 cases of patients with chronic HBV infection were enrolled from January 2010 to December 2014 in our hospital,including 88 cases of chronic hepatitis B,94 cases of HBV-related liver cirhosis,18 cases of HBV-related liver cancer (without cirrhosis) and 162 cases of liver cirrhosis merged cancer.At the same time,45 cases of healthy people were selected for normal control.The serum Apo A-1,AFP and other laboratory markers were detected,and the test results were statistically analyzed.Results The difference of Serum Apo A-1 and AFP levels in all groups was statistically significant (F =29.86,x2 =112.53,P =0.000).As the disease progressed,the serum levels of Apo A-1 gradually decreased (P ＜ 0.05).But the difference of Apo A-1 level between normal control and HBV-related liver cancer group (without cirrhosis),chronic hepatitis B and liver cirrhosis merged cancer group,liver cirrhosis and liver cirrhosis merged cancer group was not statistically significant (all P ＞ 0.05).The liver cancer patients with Child-Pugh score A,B,C had different serum Apo A-1 levels (all P ＜ 0.05);The serum Apo A-1 level of liver cancer patients with Child-Pugh score A was significantly higher than that of liver cirrhosis (t =-3.02,P =0.003),but the differences of serum Apo A-1 levels between liver cancer and liver cirrhosis patients with Child-Pugh score B and C were not statistically significant (t =0.52,1.19,P =0.610,0.240).The serum Apo A-1 levels of liver cancer patients with TNM stage Ⅰ and Ⅱ were significantly higher than those with TNM stage Ⅲ and Ⅳ (t =3.85,P ＜ 0.001).Conclusion The serum Apo A-1 levels of HBV-related liver cancer patients are related with cirrhosis,Child-Pugh score and TNM stage,and the liver reserve function,the body's stress response and many other factors may contribute to the expression of serum Apo A-1.

The gastric stump cancer is closely associated with Helicobacter pylori.Helicobacter pylori can promote the proliferation of gastric remnant mucosa epithelial cells,the production of nitroso compounds in gastric juice and abnormal expressions of some genes in human body,and finally to promote the occurrence of gastric stump cancer.The eradication of Helicobacter pylori infection is expected to reduce the incidence of gastric stump cancer.

Objective To identify antimicrobial susceptibilities of community-acquired Staphylococcus aureus infections and the risk factors of severe infections.Methods Clinical data of 184 cases of community-acquired Staphylococcus aureus infections collected from 4 hospitals in Ningbo during May 2008 and May 2013 were reviewed.Microbial sensitivity test and virulence genes ( pvl and tst) detection were performed in clinical isolates, and SCCmec genotyping was performed in methicillin-resistant Staphylococcus aureus ( MRSA) strains.Binary logistic regression analysis was used to identify the risk factors for severe infections.Results Among 184 cases of community-acquired Staphylococcus aureus infections, 39 ( 21.20%) were severe cases. Staphylococcus aureus strains were highly resistant to penicillin, erythromycin and clindamycin, but more than 75% strains were sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin.Logistic regression analysis showed that advanced age (OR=1.024, 95%CI:1.005-1.043, P<0.05), malignant tumor (OR=15.288, 95%CI:1.609-145.229, P<0.05) , autoimmune diseases or long-term hormone therapy ( OR=12.102, 95%CI:2.082-70.338, P <0.01 ) were risk factors for severe community-acquired Staphylococcus aureus infections. Conclusions Strains isolated from the patients with community-acquired Staphylococcus aureus infections in Ningbo are usually sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin, which may be recommended for clinical use.Elder patients and those with malignant tumor, autoimmune diseases or long-term hormone therapy are more likely to develop severe Staphylococcus aureus infections.

It is the measurement of high-loss dielectric to measure the permittivity and conductivity of biologic tissue.But now it is difficult to measure them accurately.Good result is got by measuring complex permittivity of phantom model at2450MHz using perturbation method,which is meaningful for the research on biologic tissue simulation by phantom model.

It is a kind of precise method tomeasure the complex permittivities of the phantom model by vector network analyzer.But it is difficult tomeasure them accurately because the phantom model is jelly-like gel and is hard tobe shaped.Network decompositon method can be used toresolve it and it has great meaning tostudy the phantom model simulating the biologic tissue.
