Background and purpose:The lymph node metastatic model of rectal tumor is a useful tool for the research on tumor occurrence, development, metastasis and antineoplastic therapy. There are few reports about establishment of larger animal model. This study aimed to establish feasible and reproducible lymph node metastatic models of VX2 tumor in rabbits.Methods:The VX2 tumor tissue was put into the puncture needle. The VX2 tumor tissue in the needle was orthotopically transplanted into the rectal wall of the New Zealand white rabbits successfully. Twenty New Zealand white rabbits were transplanted. Two experimental rabbits were scanned by MR weekly. Tumor growth curve and lymph node numbers were observed on MR. Experimental rabbit tumor volumes were measured by MR post-processing software. The rectal tumor and surrounding lymph nodes were resected, and the specimens were ifxed. The sections were stained with HE. We explored the relationship between tumor volume and growth time, the number of metastatic lymph nodes and tumor volume, respectively.Results:Thirteen models were successfully established with a rate of 65%. Tumors limited in the rectal wall were observed on the fourth week. Tumor size increased over time. There was significant difference in the tumor volume between different periods (growth cycle number) (F=52.865,P<0.05). There was a signiifcantly positive correlation between tumor volume and the growth cycle number (r=0.910,P<0.05). The metastatic lymph nodes could be observed when VT>9 cm3. The number of metastatic lymph node increased obviously from the ninth week. The more tumor volume, the greater the number of metastatic lymph nodes was observed (F=92.531,P<0.05). There was a signiifcantly positive correlation between the number of metastatic lymph nodes and the tumor volume (r=0.945,P<0.05).Conclusion:Metastatic lymph node models of VX2 tumor in New Zealand white rabbits were established successfully. This model has some value in the research on local growth, invasion mechanism, lymph node metastasis and biological characteristics of rectal cancer.

Aim To investigate the anti-tumor effects of FS-108 an Hsp90 inhibitor, on oncogene addicted EBC-1 and A375 cells. Methods SRB assay was performed to investigate cell proliferation. Immunoblot was conducted to investigate the specific proteins. FACS was conducted to test cell cycle distribution and apoptosis. Transwell assay was conducted to investigate cell motility. Results FS-108 significantly suppressed cell proliferation of EBC-1 and A375 cancer cells with IC50 at 25. 53 nmol · L-1 and 30. 02 nmol · L-1 re-spectively. FS-108 treatment triggered the degradation of key client proteins such as c-Met and B-Raf and thereby reduced their downstream AKT and ERK signa-ling pathways. The FACS analysis results demonstrated that FS-108 treatment induced G2/M phase arrest and apoptosis significantly. Furthermore, FS-108 inhibited the migration of EBC-1 and A375 cells. Conclusion As a potent Hsp90 inhibitor, FS-108 can inhibit onco-gene addicted cancer cells proliferation through induc-tion of G2/M phase arrest and apoptosis.

Objective To observe the change of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene expression during 3T3-L1 adipocyte differentiation as well as other reference gene expressions.Methods The mRNA expressions of several common reference genes were detected by real time-PCR on day 0,1,3,5,and 7 of 3T3-L1 adipocyte differentiation.Western blot was used to confirm the protein expressions of three common reference genes.Results (1) GAPDH and transferrin receptor(TFRC) mRNA expressions were significantly increased during adipocyte differentiation.GAPDH mRNA level was increased by 5.7,7.6,22.0,and 24.5 folds on day 1,3,5,and 7 after induction of adipocyte differentiation,but no apparent changes of β-actin,α-tubulin,peptidylprolyl isomerase A (PIPA),and 18S mRNA expressions were detected.The expression changes of key transcript factors for adipocyte differentiation such as PPARγ2,C/EBPα,and C/EBPβ were under-estimated by real time-PCR if GAPDH was chosen as the reference gene.Western blotting results showed that the GAPDH protein level increased gradually during adipocyte differentiation,especially on day 5 and 7 after adipocyte differentiation.There were no obvious changes of β-actin and α-tubulin protein expressions.(2) Berberine significantly inhibited mRNA and protein expressions of GAPDH in the process of adipocyte differentiation.GAPDH mRNA levels were reduced by 68.1％ and 66.3％ on day 5 and 7 after induction of adipocyte differentiation,but with no significant change in other reference genes.Conclusion It is not suitable for GAPDH to be used as an endogenous reference gene during 3T3-L1 adipocyte differentiation.

OBJECTIVE To examine the reversal effect of desipramine (DMI) on resistance to temozolomide(TMZ) in U251/TR cells and explore its mechanism. METHODS U251/TR cells were exposed to DMI (20-80μmol · L-1) or TMZ (0.5-10 mmol · L-1) for 24 h, cell viability was determined by cell counting kit-8 assay with IC50 calculated. The cytotoxicity of U251/TR cells treated with TMZ (1 or 2 mmol·L-1) in combination with DMI (20, 30 or 40 μmol · L-1) for 24 h was detected using CCK-8 assay. Synergism between DMI and TMZ was analyzed by the JIN Zheng-jun method. Apoptosis of U251/TR cells induced by TMZ 1 mmol · L-1, DMI 30 μmol · L-1,or their combination was examined by Hoechst33258 stains and caspase 3 activity was detected by luminescence analysis. Expression of C/EBP homologous protein (CHOP) was measured using quantitative real-time PCR and Western blotting. The survival rate of U251/TR cells treated with TMZ 1 mmol·L-1 and/or DMI 30μmol·L-1 was also assessed after silencing CHOP expression by small interference RNA (siRNA). RESULTS DMI or TMZ alone inhibited the growth of U251/TR cells significantly in a concentration-dependent manner (r 2=0.983,0.982,P<0.05), with the IC50 (33.6 ± 0.5)μmol · L-1 and (2.5 ± 0.6)mmol · L-1, respectively. The cell viability inhibitory rate of U251/TR cells by TMZ (1 or 2 mmol · L-1) combined with DMI (20, 30, or 40μmol · L-1) was greater than that by TMZ or DMI alone (P<0.05). The JIN Zheng-jun analysis revealed that combination of DMI and TMZ produced synergistic cytotoxicity (Q>1.15), ie, compared with TMZ alone, TMZ (1 mmol·L-1) com?bined with DMI (30 μmol · L-1) produced significant nuclear fragmentation and condensation (P< 0.05). In addition, DMI and TMZ in combination activated caspase 3 activity in U251/TR cells (P<0.05). Knock?down of CHOP by specific siRNA attenuated the synergistic effect of DMI in the presence of TMZ, the survival rate of the combined drug group raised from 51.8%to 62.2%(P<0.05). CONCLUSION The results suggest that DMI reverse resistance of U251/TR cells to TMZ through activation of the CHOP-depend?ently apoptosis pathway.

Objective Energy based surgical devices such as high frequency electrotome,Harmonic scalpel and LigaSure are widely used in thyroid operations.This study is to demonstrate the difference of tissue thermal damage among different surgical instruments.Methods 12 beagle dogs were randomly divided into 3 groups,electrotome 15 W groups (group A),three-speed Harmonic scalpel (group B) and LigaSure middle gear group (group C).Patients of each group received energy instruments operating on their thyroid tissue which mimics traditional thyroidectomy.The temperatures of gland tissue during procedures were monitored by infrared thermal imager,and the operated thyroid tissues were histologically analyzed.Results The highest temperature was (83.9±8.2)℃ in the electrotome group,(70.7±7.5)℃ in three-speed Harmonic scalpel group,and (56.6±5.7)℃ in LigaSure group.The highest temperature among the three groups was statistically significant.The electrotome (15 W) caused more serious thermal damage to thyroid tissues than that caused by either the Harmonic scalpel or LigaSure (thermal damaged depth:(0.96±0.07) mm vs (0.74±0.07) mm,P＜0.01;(0.96±0.07) mm vs (0.72± 0.11) mm,P＜0.01).Nevertheless,the thermal damage had no significant differences between the Harmonic scalpel and LigaSure group (P=0.845).The thermal damage caused by the 15 W electrotome was significantly larger than that in the other two groups,and the difference had statistical significance (P＜0.01).Conclusion Compared to the high frequency electrotome,Harmonic scalpel and LigaSure lead less tissue thermal damage during thyroid surgeries,owing to less heat production.In that way,Harmonic scalpel and LigaSure are superior to electrotome in terms of safety.
