Transarterial chemoembolization (TACE) combined the embolization with chemotherapy,whose efficacy has been verified in the treatment of hepatocellular carcinoma.Factors like the incomplete embolism,the formation of collateral circulation,neoangiogenesis and the like greatly weaken the clinical efficacy of TACE in the long term.Thus,the improvement of TACE efficacy depends on the comprehensive treatment.This paper reviewed the present application status and the progress on the treatment of hepatocellular carcinoma with TACE.

Fast tract surgery (FTS) has been implemented in different fields of surgery to attenuate the surgical stress response and accelerate recovery.Liver resection is the preferred treatment for a variety of primary and secondary liver tumors.However,liver resection is associated with severe stress response and higher rate of postoperative morbidity and mortality.Fast tract surgery has been reported to accelerate recovery following liver resection.In this review,we summarize the recent progress of fast tract surgery in liver resection.

Objective To investigate the application and administration of hyperbaric oxygen chambers in Beijing.Methods Forty-eight hospitals with hyperbaric oxygen chambers in Beijing were investigated by field investigation,letter investigation or telephone investigation.The investigation includes grades of hospital,personnel,equipment,therapy of severe cases,time of therapy and treatment plans in questionnaire.Results Hyperbaric oxygen was popular in Beijing,which ensured emergency treatments.But the scale was little relatively and the number of full-time technicians was less,besides,the therapeutic system and plans were diversified,which should be standardized.Conclusions Something must be done to improve the conditions of hyperbaric oxygen medicine in Beijing,such as cultivating personnel,standardizing therapeutic system,standardizing treatment plans,realizing computer control and so on.

Objective To investigate the mechanism of alternation of PKC activify in liver ischemia preconditioning(IP). Methods After establishment of rat liver IP model, PKC inhibitor and activator were utilized to analyze the phosphorylation of PKC and P44/42MAPKs and HSP expression, and cellular structure was also observed. All of the data were statistically analyzed. Results Compared with the control group without IP, the phosphorylation of PKC was significantly increased in IP treated models and PKC activated group(P

The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.

Objective To investigate the measurement , feasibility and clinic effect of hyperthermic intraperitoneal chemotherapy (HIPEC) guided by B ultrasound in the treatment of malignant ascites from peritoneal carcinomatosis. Methods From July 2011 to June 2013, B ultrasound-guided approach was used to perform HIPEC on 36 patients affected by malignant ascites secondary to peritoneal carcinomatosis. Every patient underwent HIPEC for three times , by way of continuous circulatory perfusion into peritoneal cavity with saline at 400 ~ 600 mL/min and intraperitoneal perfusion with 5-FU mitomycin-C and cisplatin for 90 minutes with an inflow temperature of (43 ± 0.2)℃. These patients were followed up for a long term. Results Intraoperative course was uneventful in all cases. Complete clinical regression of ascites and related symptoms was achieved in all the 26 patients, partial regression achieved in 8 patients, and no curative effect achieved in 2 cases. The acquired total clinic effectiveness was 94.44%. No postoperative deaths and complication related to the procedure occurred in this study. The KPS grades of patients rose (P < 0.001), the level of tumor markers decreased, including CA199 (P < 0.001), CEA (P < 0.001), CA125 (P = 0.003). Conclusion HIPEC guided by B ultrasound appears to be a safe, feasible and effective procedure for the treatment of debilitating malignant ascites from unresectable peritoneal carcinomatosis , which would have a clinic good perspective in future.

Objective To evaluate the security of big animals with a new bioartificial liver system .Methods Six Tibet pigs re-spectively received treatment of hybrid artificial liver and simple bioartificial liver ,observed and recorded the vital signs ,venous pressure ,transmembrane pressure and slurry pot pressure each hour ,and collected blood to make endotoxin and bacterial culture test in the zero hour ,fourth and eighth hour .Results Compared with the zero hour ,venous pressure ,transmembrane pressure ,slur-ry pot pressure were much higher in the fifth hour (P< 0 .05) ,and there were no significant difference in the rest of other time points(P>0 .05) .The mean arterial pressure and respiratory rate in all time point showed no significant changes (P>0 .05) .Com-pared with the zero hour ,the heart rate was much lower in the second hour (P<0 .01) .The values of blood endotoxin were less than 0 .5 EU/mL in the zero hour ,fourth and eighth hour from beginning ,and the bacterial culture test showed no growth of bacteria . Conclusion The experiment of big animals with a new bioartificial liver system was safe ,the efficacy in the treatment of hepatic failure could be assessed further .
