Objective To summarize the risk factors, the diagnostic and therapeutic approaches, and the outcomes of the ruptured primary hepatocellular carcinoma (PHC) occurred after transcatheter arterial chemoembolization (TACE) in order to make a further understanding of this complication. Methods The clinical data of 8 patients with ruptured PHC after TACE, who were encountered at the First Affiliated Hospital of Suzhou University during the period from Sep. 2007 to Sep. 2013, were retrospectively analyzed. Results A total of 1379 times of TACE were performed in 678 patients with PHC. Among the 678 patients, 8 developed rupture of PHC with bleeding after TACE. The overall incidence was 1.2%. The mean diameter of the tumors in the 8 patients was (11.5 ± 2.6) cm, ranging from 7.6 cm to 15.9 cm. All the lesions were located at the peripheral region close to the liver capsule, and most of them protruded outward. Five cases had coexisting portal hypertension. The average dosage of Lipiodol used in TACE was (14.9 ± 4.5) ml with a range of (8 - 20) ml. Of the 8 patients, emergency transcatheter embolization was carried out in 4 and medical management was employed in other 4. Seven patients died as all active emergency treatments failed. Only one patient, who had received emergency transcatheter embolization, survived the ruptured PHC. Conclusion Rupture of primary hepatocellular carcinoma after TACE is a rare, but very serious complication. Its occurrence may be related to lesion’s characteristics, such as large tumor size, superficial location and protrusion from the liver surface, etc. Besides, interventional management, e.g. without use of solid embolic material to enhance the embolization effect, may also be responsible for the rupture.

Objective To investigate the characteristics of lymph nodes metastasis in papillary thyroid carcinoma (PTC) and to discuss surgical approach.Methods All patients underwent total thyroidectomy,central lymph nodes and lateral lymph nodes dissection in Department of Thyroid Surgery,the First Hospital of the Jilin University,from Dec.2011 to Dec.2012.Results With the increase of the number of positive central lymph nodes,lateral cervical lymph node metastasis rate increased as well and accompanied multi region metastasis trend.In 102 cases of lateral positive cervical lymph node patients,55 cases were in level Ⅱ,accounting for 53.92％,62 cases were in level Ⅲ,accounting for 60.78％,76 cases were in level Ⅳ,accounting for 74.51％,and 17 cases were in level V,accounting for 16.67％.In lateral lymph nodes metastasis,we found level Ⅳ was the most vulnerable area,followed by level Ⅲ,level Ⅱ and level Ⅴ.Conclusions Prophylactic central lymph node dissection should be performed in PTC patients.Patients with central lymph node metastasis especially with the number of positive lymph nodes ＞ 3 should be performed ipsilateral level Ⅱ-Ⅴ lymph node dissection.

Objective To observe the level of autophagy induced by TRAIL in TT cell line and identify the role of autophagy in TRAIL-inducing apoptosis of TT cell line.Methods The growth inhibition of TT cells was measured by MTT assay.MDC staining was used to identify the happening of autophagy.Annexin V/PI double staining was used to analyze the apoptosis rate of TT cells by flowcytometry.The protein expression of caspase-8 and Beclin1 was detected by Western blot.Results ① The growth inhibition ratio of TT cells induced by TRAIL at the concentration of 250,500,1000 and 2000 ng/ml was (3.02 ± 1.82)％,(4.87 ± 1.45)％,(7.51 ± 1.57) ％,(12.76 ± 3.23) ％ respectively,which suggested significant resistance of TT cells to TRAIL.② MDC-labeled green light vesicles was significantly increased after the treatment of TRAIL for 48 h.③ The apoptosis rate of TT cells induced by TRAIL at the concentration of 500 ng/ml and 1000 ng/ml after the pretreat ment of 3-MA for 4 h was(17.83 ± 1.54) ％ and(27.81 ± 1.79) ％ respectively,which was significantly higher than the apoptosis rate induced by TRAIL(3.70 ± 0.34) ％,(6.55 ± 0.59) ％ alone and that induced by 3-MA(7.71 ± 0.64) ％ (t =3.282,P ＜ 0.05 ; t =7.830,P ＜ 0.01).④ The combination treatment of TRAIL and 3-MA increased the cleavage of caspase-8 and down-regulated the expression of Beclin 1.Conclusion Autophagy induced by TRAIL may contributes to the resistance of TT cells to TRAIL,which can be reversed by the inhibition of autophagy.

OBJECTIVE: To explore the association between low flow rate and reperfusion injury during the process of preserving liver by cold machine perfusing perfluorochemical oxygen carder solution. METHODS: Forty-four male adult Wister rats were randomly divided into normal, control, experimental Ⅰ and experimental Ⅱ groups. In the normal group, the removed liver was performed isolated reperfusion guided by Clavien method. In the other 3 groups, the removed liver was infused through the portal vein by the 4-5 ℃ conserved perfluorochemical oxygen carder solution. The infused rate was controlled at 0.4, 0.2, 0.1 mL/(min·g) with 18 hours perfusion, After that, isolated reperfusion was performed. The activity of aspartate aminotransferase, alanine transaminase and endotheiin mass concentration of the effluent was detected at minutes 10, 30, and 60 after reperfusion. The histopathological changes of liver under light and election microscopy were also observed. RESULTS: The activity of aspartate aminotransferase, alanine transaminase and endothelin mass concentration had no remarkable differences between the experimental Ⅰ group and control group (P > 0.05). The differences between the experimental Ⅱ group and control group were remarkable (P < 0.05). The light and electron microscopy showed that the histopathological changes of liver in the control and experimental Ⅰ groups was lightener than experimental Ⅱ group. CONCLUSION: During the process of preserving liver by cold machine perfusion, the rate of 0.1 ml/(min·g) perfluorochemical oxygen carder solution increase the injury of hepatocyte and sinusoidal endothelial cells, which eventually result in severity of reperfusion injury.

Phospholipase D(PLD) is ubiquitous in bacteria,fungi,and mammal.In pathogenic microorganisms,PLD can be pathogenic determinant and play a role in spore generation.In mammalian cells,PLD functions in several signal transduction pathways,such as membrane transportation,mitosis regulation,and actin cytoskeleton regulation.In the process of pathogens invasion host cells,both of the pathogen and host cells’ PLD will be activated and a series of cascade reaction will be generated.During this process,pathogen’s PLD can regulate the polymerization and reorganization of its own actin filaments and induce the polymerization or reorganization of the host cell actin filaments near the foci,thus to promote the phagocytosis of the pathogen by host cell.Investigating the role of PLD activation in the infection will be significance for further understanding the molecular mechanism of pathogen-host cell interaction.

Objective To execute experimental study injection rate and volumetric error and to explore their correlations with sizes of injectors and extension tube,so as to lay a foundation for the quality control of the injection pump.Methods Simulation experiment was carried out with involving in 10,20 and 50 ml of injectors and 80 and 120 cm extension tubes,and 6 kinds of connection systems were formed with auxiliary appliances.The injection rate and flow reading of the flow meter were obtained and then compared with the set values,and the correlations were proved between sizes of auxiliary appliances and the precision of injection dose and rate.Results In case other conditions kept the same,the injector with larger capacity behaved better in controlling injection rate and dose,and the shorter extension tube gained advantages over the longer one in regulating the precision for injection and injection dose.Conclusion The experiment contributes to the selection of auxiliary appliances and the enhancement of quality control,and the further research provides references for process design and materials selection of the injector.
