Oncogene c-jun is a member of jun family,the immediately early genes(IEGs),and belongs to one of the nuclear transcription factors of basic leucine zipper(bZIP)family.Combined with many gene promotors,c-jun is involved in the regulation of gene transcription.Its products play important roles in regulating gene expression,cell proliferation,differentiation and apoptosis.The structure,biological funetion,regulation of c-jun and its roles contributing to tissue damage are reviewed in this article,which may provide understanding for severity of tissue injury and wound age estimation in the field of forensic pathology.

Objective To investigate the efficacy of the Ivor-Lewis cervical stapled esophagogastrostomy via thorax in the treatment of middle esophageal carcinoma.Methods The clinical data of 303 patients with middle esophageal carcinoma who were admitted to the Rugao Boai Hospital (107 patients) and the Rugao People's Hospital (196 patients) from March 2005 to March 2013 were prospectively analyzed.All the patients received Ivor-Lewis stapled cervical esophagogastrectomy (Ivor-Lewis group,151 patients) or Sweet stapled cervical esophagogastrostomy (Sweet group,152 patients) according to the admission order.The intraoperative condition,perioperative complications,lymph node dissection and postoperative follow-up of the 2 groups were analyzed.All the patients were followed up via out-patient examination till December 2012.The measurement data,enumeration data and the ranked data were analyzed using the independent samples t-test,chi-square test or Fisher exact probability and Wilcoxon rank sum test,respectively.The survival curve was drawn by the Kaplan-Meier method,and the postoperative mortality rate was analyzed using the Cox proportional hazard model.Results The operation time of the Ivor-Lewis group was (239 ± 21)minutes,which was significantly longer than (188 ± 30)minutes of the Sweet group (t =11.32,P ＜ 0.05).The surgical resection rate of the Ivor-Lewis group was 98.68％ (149/151),which was significantly higher than 92.76％ (141/152) of the Sweet group (x2 =6.45,P ＜ 0.05).The positive rate of the upper resection margin of the esophagus,postoperative morbidity rate and operative were 0.67％(1/149),10.07％ (15/149) and 0 in the Ivor-Lewis group,and 0.71％ (1/141),11.35％ (16/141) and 0.71％(1/141) in the Sweet group,with no significant difference between the 2 groups (P ＞ 0.05).The number of lymph nodes dissected from the cervical-thoracic junction and the upper abdomen were 3.6 ± 1.1 and 3.5 ± 1.1 in the Ivor-Lewis group,which were significantly greater than 2.3 ± 0.8 and 2.4 ± 0.8 in the Sweet group (Z =9.96,9.02,P ＜ 0.05).The number of positive lymph nodes dissected from the cervical-thoracic junction was 0.7 ± 1.1 in the Ivor-Lewis group,which was greater than 0.3 ± 0.6 of the Sweet group,with significant difference between the 2 groups (Z =3.26,P ＜ 0.05).Of the 290 patients who received surgical treatment,273 were followed up with the follow-up rate of 94.14％ (273/290),and the median time for follow-up was 28.0 months.The 1-,2-,3-year tumor recurrence rates were 8.21％ (11/134),19.64％ (22/112) and 29.35％ (27/92) of the Ivor-Lewis group,which was significantly lower than 19.05％ (24/126),35.24％ (37/105) and 44.19％(38/86) of the Sweet group (x2=6.55,7.33,5.03,P ＜ 0.05).There were significant differences in the 1-,2-,3-year locoregional recurrence rate of the lymph nodes between the 2 groups (x2 =7.03,9.68,6.87,P ＜0.05).The 1-,2-,3-year accumulative survival rates of the Ivor-Lewis group were 90.30％ (121/134),80.36％(90/112) and 71.74％ (66/92),which were significantly higher than 80.95％ (102/126),59.05％ (62/105)and 51.16％ (44/86) of the Sweet group (x2=4.65,1 1.73,7.97,P ＜ 0.05).Conclusion Ivor-Lewis stapled cervical esophagogastrostomy via thorax has advantages of high resection rate,better safety and better quality of life of patients,and it could be an optimized design of the treatment for patients with middle esophageal cancer without intumescent lymph node of neck.

Objective To investigate the effects of four tyrosine metabolites on the proliferation, cell cycle and chemosensitivity of lung cancer cells.Methods A549 cells were cultured with different concentrations of tyrosine metabolites:tyrosine, 4-hydroxyphenylpyruvate(HPPA), homogentisic acid(HGA) and fumaric acid (FA) in vitro.High content imaging analysis system was used to monitor cell proliferation.Flow cytometry was used to detect cell cycle and apoptosis.Protein and mRNA level of Bax and Bcl-2 were measured by Western blot.Results Tyrosine metabolites had no effect on cell cycle and proliferation of A549 cells.HGA decreased the cell apoptosis of A549 cells induced by Gefitinib with depressed Bax expression and elevated Bcl-2 expression.However, FA increased the apoptosis of A549 cells induced by Gefitinib with up-regulation of Bax and down-regulation of Bcl-2.No obvious effect of tyrosine and HPPA was detected on Gefitinib induced cell apoptosis.Conclusion HGA and FA may play an important role in drug sensitivity of lung cancer cells, indicating a critical role of tyrosine metabolism in lung cancer.

Objective To generate the erythroid differentiation associated gene(EDAG) knockout mice and analyze their sensitivity to low dose radiation-induced damage.Methods Zinc finger nuclease technology ( ZFNs ) was used to produce the EDAG knockout mice.The low dose radiation-induced damage was evaluated by peripheral blood cell counts, DNA damage and colony formation of bone marrow cells.Wild-type and EDAG knockout mice were irradiated with 0.31 Gy/min X-ray, one minute per day for seven consecutive days, and the cumulative radiation dose was 2.17 Gy(n=7).The blood cell counts were measured by an automated hemocytometer.DNA damage was detected by immunofluorescence assay with a DNA damage marker p-H2A.x antibody (n=3).The colony formation ability of bone marrow cells was evaluated with a semi-solid culture medium(n=3).Results A model of EDAG knockout mice was established.Compared to wide type mice, white blood cell counts of EDAG knockout mice decreased significantly while the DNA damage marker p-H2A.x expression was increased on the third day after X-ray irradiation.The ability of colony-forming was reduced after 7 days of X-ray irradiation.Conclusion Our present study found that EDAG knockout mice are more sensitive to low dose radiation-induced damage as shown by decreased peripheral blood cells counts, reduced colony-forming ability of bone marrow cells, and increased DNA damage.These results suggest that EDAG knockout mice can serve as a powerful tool for evaluation of the biological effects of low-dose radiation damage.

OBJECTIVETo construct a GFP/Puro double-labeled lentiviral expression vector for CK8 silencing and assess the effects of CK8 silencing on cell apoptosis.

METHODSThe siRNA sequences of CK8 were inserted into the lentiviral expression vector GV248 and transfected into 293T cells with the packaging plasmids PMD and SPA. The lentivirus was collected at 24 and 36 h post-transfection. Flow cytometry was used to detect the virus titer and the positive cells were selected with puromycin. The knockdown of CK8 was examined by Western blotting. The effect of CK8 down-regulation on cell apoptosis induced by cisplatin was detected with Annexin V/PI staining.

RESULTS AND CONCLUSIONWe successfully constructed CK8 interference lentiviral vector and obtained a stable cell line with CK8 knock-down that was sensitive to cisplatin-induced apoptosis.
