Post-operative recurrence and metastasis remain the leading causes of death for patients with gastric cancer. The major determinants of recurrence and metastasis are the biological characteristics of cancer cells and the immunological status of the patients. In recent years, due to the target-specificity, biotherapy has yielded efficacious responses in diverse clinical applications for cancer treatment, partially for the treatment of recurrence and metastasis of gastric cancer. However, because of the high diversities in clinical manifestations, patients' condition, and tumor's characteristics, there is no ideal strategy of biotherapy established for the prevention and treatment of recurrence and metastasis in gastric cancer. Therefore, a lot of work need to be done in basic research and clinical trial to make the biotherapy effective in treatment of gastric cancer recurrence.

This study was aimed to discuss the ways of converting clinical data entered in the Case Report Form (CRF) to Study Data Tabulation Model (SDTM) database format in clinical research of traditional Chinese medicine (TCM). Currently, there were three approaches for implementing SDTM, which were the pure SDTM approach, submission-only approach and database-only approach. This article compared and analyzed advantages and disadvantages of three approaches and introduced experiences of the Clinical Evaluation Center of China Academy of Chinese Medical Sciences using database-only approach for SDTM implementation. The results showed that pure SDTM approach can maximally embrace SDTM standards. However, the current process and software system should be modified. Therefore, it was time-consuming and expensive. The submission-only approach was the most economic way in the application of SDTM standards. However, the data quality and traceability may not be guaranteed. The database-only approach built the study database based on the SDTM standard by writing transformed program before data entry while the data collection system was not SDTM-compatible. It was concluded that database-only approach for implementation SDTM was a suitable and practical way to TCM clinical research.

Objective To explore the expressions of Survivin and VEGF and relationship between them in hepatocellular carcinoma(HCC).Methods The expressions of Survivin protein and VEGF protein in 50 HCC.30 cirrhosis and 10 normal tissues were assessed by immunohistochemical method.The expressions of Survivin mRNA and VEGF mRNA in 50 HCC,30 cirrhosis and 10 normal tissues were assessed by in situ hybridization.Results The expressions of Survivin and VEGF in cancer tissues,cirrhosis tissues,normal tissues weresignificantly different. The expression of Survivin in HCC tissues was stronger than that in cirrhosis,but the expreesion of VEGF in cirrho- sis was stronger than that in HCC tissues.Conclusion The expression of survivin.is closely associated with the ex- pression of VEGF in HCC and they take positive correlation.The abnormal expressions of Survivin and VEGF are closely associated with the development of HCC.They may play important roles in the development of HCC.

AIM:To study the effect of berberin hydrochloride(Ber)on the elevation of blood concentra- tion of Cyclosporin A(CsA)and liver and renal functions in renal transplanted recipients.METHODS:138 cases with renal transplantation in experimental group were treated with CsA and Ber and 150 cases with renal trans- plantation in control group received CsA only.Blood lev- els of CsA,biochemistry indexes for liver and renal func- tion were determined.RESULTS:After 1,3,6 months combined with Ber,blood concentrations of CsA in pa- tients went up by 49.8%,81.4%,36.9% and the radios of blood concentration of CsA to CsA dosage increased 88.8%,102.0%,72.5% compared with those before taking Ber(P

Objective To evaluate the efficacy and adverse effects of gefitinib in the treatment of fe- male patients with advanced adenocarcinoma of lung who had failed to previous chemotherapy.Methods These patients received 250mg of gefitinib orally,once daily until disease progression or development of intol- erable toxic reaction.They were evaluated one month after treatment and every other month thereafter.Results Among the 27 evaluable patients,there were 1 CR(3.7%),11 PR(40.8%),10 SD(37.0%)and 5 PD(18.5%). The overall response rate was 44.5%(95% CI 29%～68%);and 22 patients(81.5%)gained profit(CR+PR+ SD)from the clinical therapy(95% CI 62%～94%);the mean TTP was 7.2 months.Symptomatic improvement rate was 80.0%.The main adverse effects were mild rash and diarrhea.Conclusion gefitinib has significant efficacy in the treatment of female patients with advanced tung cancer who had failed to previous chemother- apy.Adverse effects are mild.gefitinib is a suitable therapy for these patients.

OBJECTIVETo follow up the cohort of a certain factory and analyze the death cause of the employees.

METHODSA dynamic cohort was adopted and the study population consisted of all workers stayed at the factory for more than 1 year. The cohort data was mainly from the personnel ministry in the factory,the death data provided by the personnel ministry,the labour union and the hospital. All cause of death of the all employee and the death condition of radiation group and no-radiation group were analyzed and compared.

RESULTSThe mortality of the workers in the factory was significantly lower than national population, the SMR of all cause of death in all employee, radiation group and no-radiation group were 0.41 (95% CI: 0.37-0.45), 0.24, 0.75 respectively; all cancer death in the three group was 0.59, 0.40 and 0.92. But the death order was different in radiation group and no-radiation group,the order of liver cancer was list first in radiation group, which was unlike that of the nation order and the no-radiation order.

CONCLUSIONThere have no excess death in the factory, but the order of liver cancer is precedence.

OBJECTIVETo investigate the effect of total mesorectal excision(TME) and preoperative therapy on local recurrence in rectal cancer.

METHODSRectal cancer patients who received TME in School of Oncology, Peking University, from January 2000 to August 2004 were enrolled in the study group. Patients who received surgical resection for rectal cancer from January 1996 to December 1999,before the introduction of TME,were chosen as controls. Postoperative complications and local recurrence were compared. Clinicopathological and follow- up data were analyzed.

RESULTSThere were 161 patients in the TME group and 173 as controls. The intra- operative blood loss was significant less,hospital stay shorter,and lymph nodes harvested more in TME group than those in the control group,there was no difference in complication rate between the two groups. Local recurrence (LR) rate was 2.5% in TME and 8.0% in the control group, respectively (chi2=5.144; P=0.023). In TME group,the local recurrence rate was 1.8% in the 77 patients with preoperative therapy,and 2.9% in the other patients without preoperative therapy (P=0.182). Logistic regression analysis revealed that TME and vessel cancerous emboli were major risk factors for local recurrence of rectal cancer.

CONCLUSIONTME and vessel cancerous emboli are major risk factors for local recurrence of rectal cancer.

Objective To observe the influence of nandrolone phenylpropionate(NP) on the ultrastructure of aorta in rats with or without movement training,and investigate the side effects of NP on the cardiovascular system. Methods Forty male SD rats were randomly divided into sedentary control group,sedentary+medicine group,exercise control group and exercise+medicine group.For the groups with medical treatment,NP of 10 mg/kg one time every three days was injected into the rats via gluteus for eight weeks.For the exercise groups,rats were trained to run on treadmill five days per week for eight weeks.The aortae were sampled and specimens were obtained for transmission electron microscopy. Results The ultrastructure of aorta was normal in sedentary control group.For sedentary+medicine group,mitochondrial swelling,vacuolated cytoplasm and lysis of endothelial cells were observed,disruption of intercellular conjunctions,widening of subendothelial spaces and furcation and breakage of internal elastic lamina were found,and smooth muscle cells changed into synthesis type.For exercise control group,no obvious morphologic change was observed,except that part of the internal elastic lamina disrupted.In exercise+medicine group,breakage and lysis of endothelial cells were observed,widening of subendothelial spaces and lysis of internal elastic lamina were found,and autophagosome and myelinoid body were seen in smooth muscle cells. Conclusion NP may lead to the impairment of endothelial cells and the change of smooth muscle cells into synthesis type.Exercise with NP administration may result in more severe impairment in vessel wall.
