Objective To define the correlation between the proliferating cell nuclear antigen (PCNA) and metastasis-related gene nm-23-H 1, and to correlate their espressions with clinical features,radiosensitivity and prognostic variables in exophageal squamous cell carcinoma (ESCC), to establish some biological parameters obtained prior to therapy though which we can predict radiosensitivity and outcome.Methods PCNA and nm-23-H 1 expression protein were determined by immunohistochemical technique with formalin-fixed paraffin-embedded specimens from 59 patients with ESCC who had received definitive radical radiation and had been followed up for more than 3 years. The values were assessed by distributions of patients , disease factors, including age,sex,lesion site,legth ,histological grade and prognosis.Results The findings showed that the mean labelling indices of PCNA and nm-23-H 1 were significantly higher in ESCC than in the normal esophageal tissue (P0.05).Conclusions PCNA and nm-23-H 1 indices can be taken as biological endpoints to predicting therapeutic response, local and systemic control of disease.

Objective　To discuss the development and the invasive transfer mechanism.Methods　Cell culture method, p53 protenin immunohistochemistry, PCR-SSCP examination, zymography, PCM and heterogenic inouclation test inside the nude mice were adopted. Results　p53 genetic mutation existed in human melanoma cells. The fluorescent positive rate of 67KD LN-R on the surface of the melanoma cell and the average flurescent intensity are repectively WM451＞WM983A＞WM1341B＞WM35.Early WM35 did not produce MMPs; WM1341B only produced 72KDa(MMP-2),not 92KDa(MMP-9);Both WM983A at progressive stage and distal transfering tumor WM45 produced 72KDa and 92KDa. WM983A and WM451 were also seen to form evident transfering tumor inside the naked mice.Conclusion　p53 genetic mutation, the production of MMPs and the high indication of 67KD LN-R on the celluar surface are the key factors for the human melanoma cell to obtain invasive transferring abililty.

Objective To investigate the relationship between rapists and related allele genes based on the analysis of 15 short tandem repeats (STRs) loci genetic polymorphism. Methods The method of Genome-wide scan was being used. Buccal swab samples of 129 rapists and 156 random populations were collected and PCR compound amplification was carried out with the aid of AmpFISTR Identifiler system. Then the products were subjected to electrophoresis and gene detection with AB13100 type gene analysis system so as to calculate and compare the alleles of 15 STRs gene frequency in the two groups. Results All the 15 STRs loci allele gene frequency in rapists and random population was found to coincide with Hardy-Weinberg law(P>0. 05). Allele 28 of D21S11 (rapists: 1.55% ,control group:5. 13%) ,allele22 of FGA(rapists:24.03% ,control group:16.99%),allele23 of FGA(rapists: 17.05% ,control group:26.28%) ,allele 10 of TH01(rapists:1.16% ,control group:4.17%) ,allele 8 of TPOX(rapists:55.77% ,control group:63.77%),allele 12 of TPOX(rapists:4.26% ,control group: 1.28%) were different between the two groups (P< 0.05) .while it is no differ significantly in other STRs loci allele gene(P >0.05). Conclusion Allele 28 of D21 S11,allele 22 and 23 of FGA, allele 10 of TH01, allele 8 and 12 of TPOX may be associated with the violent crime of rape. It is suggested that there are existing sensitive or resistance genes about the violent crime of rape in chromosome 2,4,11,21.
