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.

0.05),while the changes in the serum levels of AST and ALT in the recipients in of treatment group were obviously lower(P

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

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.

Objective To screen the differentially expressed proteinin the livetissue of the drug-induced acute hepatifail-ure rat.MethodTwenty-foumale SD ratwere randomly divided into two group,the experimental group (12 cases) wagiven D-galactosamine10g/L by intraperitoneal injection and the control group (12 cases) wagiven normal saline by intraperitoneal injec-tion .The total proteinin the livetissue samplewere extracted ,quantitated ,and subjected to separate by the two-dimension elec-trophoresis(2-DE) of isoelectrifocusing (IEF) and SDS-PAGE ,found outhe discrepanprotein spotby the software and per-formed the identification by MALDI-TOF-M.Result27 differential protein spotwere successfully identified ,and 15 up-regula-ted and 12 down-regulated proteinexpressionwere obtained in the experimental group compared with the control group .Conclu-sion The significandifferencein the expressionof protein,such acasein kinase I(CKⅠα) ,tyrosine protein kinase(PTK) ,pro-liferating cell nucleaantigen(PCNA) ,et.in the liveexisbetween the acute hepatifailure model ratand the normal one.

Objective To develop a gas dynamic exposure device with a simple structure.Methods The device was composed of a water tank, an gas chest, an exposure kit and an gas-out bottle. The chest body was made of organic glass pane, drainage method was used to distribute the gas properly, and airflow was regulated with the gravity and valve.Results The device was proved to have simple structure and high effects.Conclusion The device has low cost, simple structure and properly distributed gas, and can be reused for exposure test.

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 .

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 estimate the safety,feasibility and generalization of three point single-incision laparoscopic cholecystectomy (SILC).Methods The clinical data of 1 126 patients who underwent three-point SILC at the second department of Hepatobiliary Surgery of Zhu Jiang Hospital,Southern Medical University From January 1,2011 to December 30,2015 was analyzed retrospectively.The patient who were indicated for conventional laparoscopic cholecystectomy were included,but those suspected malignant diseases of gallbladder were excluded.Results Of the 1126 patients,the surgery was performed successfully in 923 patients,and 192 patients need extra ports due to the adhesion and difficulty of exposing the Calots triangle,and 11 were converted to open surgery due to severe adhesion,with the success rate being 81.9％.The operating time was (29.5 ± 12.2) min (from the entrance of laparoscope to the removing of gallbladder),the blood loss was (8.7 ± 7) ml,and the hospital stay time was (1.4 ± 0.7) d (after surgery).There were three cases of bile duct injury:two of them were bile leak of aberrant duct,one of them was bile leak of cystic duct damaged by heat.And there was one case of injury of duodenum,22 cases of umbilicus hematoma,13 cases of hematoma of thorax,and 2 cases of thoracic hemorrhage who required surgery.There were no hernia,aerothorax and so on.Conclusion Three point SILC is a technology that is safe,maneuverable and suitable for being carried out in clinical practice.
