Objective To investigate the expressions and clinical significance of Ki-67,p53,and survivin in esophageal cancer and precancerosis.Methods The expressions of Ki-67,p53,and survivin proteins were detected by immunohistochemical staining in 40 normal esophageal mucosa,136 precancerosis (42 mild atypical hyperplasia,43 moderate atypical hyperplasia,and 51 severe atypical hyperplasia),and 68 esophageal cancer tissues.The correlation of three proteins expressed in esophageal carcinoma tissues was analyzed.Results The positive expression rate of Ki-67 was 0 (0/40)for normal epithelium,35.7％ (15/42) for mild dysplasia,51.2％ (22/43) for moderate dysplasia,74.5％ (38/51) for severe dysplasia,92.6％ (63/68) for squamous carcinoma,respectively.The positive expression rate of p53 protein was 0 (0/40) for normal epithelium,28.6％ (12/42) for mild dysplasia,46.5％ (20/43) for moderate dysplasia,52.9％ (27/51) for severe dysplasia,67.6％ (46/68) for squamous carcinoma,respectively.The positive expression rate of survivin protein was 0 (0/40) for normal epithelium,38.1％ (16/42) for mild dysplasia,55.8％ (24/43) for moderate dysplasia,64.7％ (33/51) for severe dysplasia,89.7％ (61/68) for squamous carcinoma,respectively.Rank correlation analysis showed that abnormal expressions of Ki-67,p53,and survivin were correlated significantly with the pathological grading of the lesions (r =0.637,0.454,0.590,P ＜0.01).The expressions of Ki-67,p53,and survivin were positively correlated in esophageal carcinoma (r =0.407,0.646,P ＜ 0.01).Conclusions The abnormal expressions of Ki67,p53,and survivin were associated with the processes of the esophageal canceration,and the joint detection with three parameters has important clinical value.

Objective To construct the prokaryotic expression vector bearing fusion gene NT4-ADNF-9 and lay foundation for further study on genetic therapy of neuraseusory deafness. Methods By means of asymmetrical prince/ template, double stranded eDNA of activity dependent neurotrophic factor-9 (ADNF-9) was obtained, which included restriction enzymes sites on the two extremities. ADNF-9 eDNA was ligated to the signal and leader peptides of nenrotrophin 4 (NT4), and the fusion gene was named NT4-ADNF-9. Then it was suheluned into prokaryotic expression vector pBV220, and called pBV220/ NT4-ADNF-9. Results Evidences of DNA sequence analysis and restrtction enzymes digestion showed that we recombined ADNF-9 eDNA to the 3'terminal of the signal and leader peptides of NT4, and the fusion gene was subcluned into pBV220 successfully. Bioactivity of the products was proved that it could support the cell survival and neurite growth in the primary cultures of dorsal root ganglia (DRG) of embryonic day-8 cbicken neurons as compared to the control. Conclusion Prokaryotic expression vector pBV220/NT4-ADNF-9 can be constructed successfully and the bioactivtty is satisfactory.

Objective To explore the anti-inflammatory and antipruritic effects of Chushizhiyang ointment in a mouse model. Methods A total of 40 male 8-week-old BALB/c mice were included in this study, and randomly and equally divided into 4 groups. A mouse model of atopic dermatitis (AD)was established in three groups of mice by repeated application of 2,4-dinitroflurobenzene (DNFB)to shaved abdominal skin for sensitization and to shaved dorsal skin for stimulation. After establishment of the AD model, the three groups were topically treated with sodium chloride physiological solution (model group), hydrocortisone cream (hydrocortisone group)and Chushizhiyang ointment (Chushizhiyang group)respectively for 14 consecutive days. The remaining group receiving no sensitization or treatment served as the normal control group. All the mice were sacrificed 12 hours after the final treatment, and the dorsal skin of mice was resected followed by the determination of skin thickness and weight as well as hematoxylin-eosin(HE)staining and toluidine blue staining for the counting of leukocytes and mast cells respectively. Moreover, enzyme-linked immunosorbent assay(ELISA)was performed to measure the levels of interferon-gamma(IFN-γ), tumor necrosis factor alpha(TNF-α), interleukin 4(IL-4)and IL-5 in dorsal skin lesions. In addition, a local skin itching model was induced by histamine phosphate in Hartley guinea pigs, which was used to explore the effect of Chushizhiyang ointment on itch thresholds. Results Compared with the model group, both the Chushizhiyang group and hydrocortisone group showed reduced thickness and weight of dorsal skin in mice (all P < 0.01), numbers of infiltrating lymphocytes and mast cells (all P < 0.01)and levels of IFN-γ, TNF-α, IL-4 and IL-5 in skin lesions (P < 0.05 or 0.01)on day 15 after the start of treatment. The thickness and weight of dorsal skin in mice were significantly decreased in the hydrocortisone group (P <0.01), but experienced no significant changes in the Chushizhiyang group compared with the normal control group. Additionally, Chushizhiyang ointment could significantly increase itch thresholds in guinea pigs induced by histamine phosphate(P < 0.01). Conclusions Chushizhiyang ointment can significantly inhibit DNFB-induced AD in mice, likely by restoring the balance between Th1 and Th2 type cytokines. Moreover, Chushizhiyang ointment could markedly relieve itching induced by histamine phosphate in guinea pigs.
