The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. METHODS: Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. RESULTS: MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. CONCLUSION A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.

Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.
