Human fetal esophageal epithelial tissue were cultured in vitro and treatedwith mycotoxins of Alternaria alternata (AME or AOH) for 4 h. The genomic DNAwere extracted from these tissues. Genomic DNA was isolated from normal human fetalesophageal epithelium (as blank control), DNA from malignant tissue and its adjacentnormal mucosa was obtained from esophagectomy patients. DNA was amplified with PCRreaction, using genomic DNA as templet. The PCR products was a 104bp fragment from which the 12 codon of c-Ha-ras gene was contained. The excition point of restriction en-zyme Hpe Ⅱ was located in this fragment. The PCR amplified 104bp fragment was diges-ted by Hpa Ⅱ and analysed by agarose gel electrophoresis. The results showed that the104bp fragment amplified from genomic DNA of blank control and esophagectomy patientcould be digested by Hpa Ⅱ ; but that from genomic DNA of human fetal esophagealepithelium treated by AME or AOH could not. These results indicated that a mutationhad taken place at 12-codon of c-Ha-ras gene after it was treated by AME, AOH for ashort time. The mutation of Ha-ras gene might be the early event during esophageal car-cinogenesis. The effect of AME and AOH during the onset of esophageal cancer and themolecular machanisms of the effect were worth of further study.

Recombinant human endostatin (Endostar) is a broad spectrum molecular targeted drug on anti-angiogenesis that the main evidence-based data is combined chemotherapy treatment of advanced non-small cell lung cancer (NSCLC).In recent years,the researches of recombinant human endostatin used in the treatment of various malignant tumors are on the increase and achieve good effect.In addition,the researches about combined treatment methods,routes of administration,methods of medication are carried out gradually,which will be conducive to the reasonable application in clinical.

Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

Hyperthermia is a means of adjuvant therapy, which have a sensitizing effect to radiotherapy and chemotherapy. In recent years, the molecular biology, cell and animal experimental research of tumor thermochemotherapy progressed very quickly, which provide theoretical foundation and guidance for us to further develop hyperthermia combined with chemotherapy in clinical trials. In this paper, the studies with the mechanism of thermo-chemotherapy treatment of tumor, different ways of thermochemotherapy and commonly used drugs in thermochemotherapy are reviewed.

OBJECTIVETo study the over-expression of mutant p53 protein in non-mucinous adenocarcinoma in-situ (NMAIS) and invasive adenocarcinoma, NOS of lung.

METHODSImmunohistochemical study for p53 protein was performed on 17 cases of NMAIS and 70 cases of invasive adenocarcinoma, NOS of lung. The difference in p53 over-expression between the two tumor subtypes was analyzed.

RESULTSThe over-expression of mutant p53 protein was observed in 0 case (0%) of NMAIS and 37 cases (52.9%) of invasive adenocarcinoma, NOS of lung. The difference was of statistical significance (P = 0.000).

CONCLUSIONMutant p53 protein over-expression may play a role in the progression of NMAIS to invasive adenocarcinoma, NOS.
