Objective To evaluate the clinic effect of local resection plus axialla lympha nodes dissection on treating early stage breast cancer. Methods 112 cases of early stage breast cancer in PLA309 Hospital were divided into 2 groups: local resection plus axially dissection group (46 cases) and Halsted's operation group (66 cases). The survival rate,local recurrence rate,metastasis rate, and casmetic effect of breast were followed up for long time. Results In treatment group, the 3,5,8 years survival rates were 97.8%, 80.5%, 76.1% respectively. In control group 3,5,8 years survival rates were 97.0%, 87.9% and 71.2% respectively. The rate of local recurrence was 4.3% in treatment group and 4.6% in control group.The metastasis rate in treatment group was 19.6%, in control group was 16.7%. 93.2% of patients in treatment group kept good breast figure. Conclusions Local resection plus axially dissection, with the same effect as Halsted procedure, is an ideal method in treating early stage breast cancer.

Objective To investigate the pathological and clinical effects of preoperative intra arterial infusion chemotherapy for patients with advanced breast cancer.Methods The clinical data of 52 patients with advanced breast cancer were analyzed retrospectively.Twenty two patients were treated with preoperative intra arterial infusion chemotherapy (treatment group),and 30 were treated without preoperative intra arterial infusion chemotherapy (control group).Results In the treatment group,the tumour size reduced and symptoms relieved after intra arterial infusion chemotherapy in 86.4% of the patients.Pathological examination of the specimens showed that raryopyknosis,raryorrhexis,cytoplasm coagulation and necrosis in cancer cells around the vascular vessels were found in all patients.Interstitial edema,inflammatory cells infiltration ,fibroelastosis around the cancer cells,proliferous intima thrombus and inflammation of vessels were also found.But in the control group,the histological chang of cancer cell was not found yet.All patients were followed up for 2 to 7 years.Local recurrence rate in the treatment group was 13.6%, while that of the control group was 33.3% (P

OBJECTIVETo evaluate the value of infusion chemotherapy by pump implantation via hepatic artery or portal vein or both (double-pump chemotherapy, DPC) for hepatic metastasis from colorectal cancer.

METHODSThirty patients with hepatic metastasis from colorectal cancer were divided into three groups: 1. Group I-DPC (12 patients). 2. Group II-hepatic artery implantation chemotherapy (10 patients) and 3. Group III-portal vein implantation chemotherapy (8 patients).

RESULTSResponse rate was 66.7% in group I, 60% in group II and 37.5% in group III. The 0.5-, 1-, 2-year survival rates were 100.0%, 75.0%, 41.7% in group I, 90.0%, 60.0%, 30.0% in group II and 87.5%, 50.0%, 25.0% in group III.

CONCLUSIONDouble pump implantation chemotherapy is effective in treating hepatic metastasis from colorectal cancer. It is better than hepatic artery or portal vein pump-implantation chemotherapy alone.

AIMTo establish a simple and effective method for RBCs labeling and survival assays, and the qualities of rabbit RBCs preserved in GMA solution at 4 degrees C were verified.

METHODSThe bloods were taken through the ear arteries of the rabbits. The RBCs were labeled by fluorescein isothiocyanate (FITC), and were reinjected to the same rabbit through ear veins. The percentage of FITC labeled RBCs was assayed by FACS at a series of times after injection. The SAS software was employed to analyze the data and establish the regression equations. The 24-hour recovery and the half-life span of the labeled RBCs were calculated according to the equations.

RESULTSThe 24-hour recovery and the half-life span of the labeled RBCs in the control group were 93.76% +/- 5.40% and 22.50% +/- 4.37 days respectively, which was in agreement with the previous papers. The 24-hour recovery and the half-life span of the labeled RBCs in the GMA group were 89.13% +/- 7.10% and 11.41% +/- 1.63 days respectively, which was coincident with the infusion conditions.

CONCLUSIONCompared with other methods of RBCs labeling in vivo, FITC labeling was thought to be easier and cheaper to use, which could facilitate the analysis of the biological character of the labeled cells, and could be used to trace the fate of labeled cells.

OBJECTIVETo evaluate the effect of operative selective pump-insertion into the tumorous target artery, postoperative regional infusion chemotherapeutant and immunizator for treatment the latter gastrointestinal cancer.

METHODSThe effect of operative super-selective pump-insertion into the tumorous nutritious artery, postoperative regional infusion chemotherapeutant and immunizator for treatment 88 cases patients suffering from irremovable gastrointestinal cancer was observed. Of them, 45 cases were gastric cancer, 31 cases were rectal cancer, 11cases were colic cancer.

RESULTSComplete response 2 case; Part response 77 cases, 11 cases patients had received secondary resection after intraarterial chemotherapy. Non chang 9 cases; effective rates reach to 89.8%. One, two and three years survival rates were 86.4%, 30.7% and 10.2%. Average survival period were 21.5 mouths.

CONCLUSIONSuper-selective pump-insertion into the artery and regional intraarterial chemotherapy is an efficient way in treatment of the latter gastrointestinal cancer, which can delay the survival period of patients with tumor, and increase the resectable rate.

OBJECTIVETo explore the susceptibility of children to develop intrauterine hepatitis B virus (HBV) infection through studying the association between interferon gamma (IFN-gamma) + 874 single nucleotide polymorphism (SNP) and intrauterine HBV infection.

METHODSThe subjects were selected from outpatients who were in our hepatitis B (HB) vaccine following-up clinics. The subjects whose mothers were HBV carriers were inoculated with HB vaccine or HB vaccine and hepatitis B immunoglobulin (HBIg). Intrauterine HBV infection was defined as peripheral blood HBsAg and/or HBV-DNA positive at birth and lasting for six months (group I). Normal immune children were defined as peripheral blood negative for HBV marker since birth and afterwards HBsAb titers were above protective level (group II). The subjects were composed of the following two groups. Group I consisted of 46 children with intrauterine HBV infection. Group II was composed of 73 normal children. A Taqman fluorescence polymerase chain reaction for the IFN-gamma + 874 SNP was performed for both groups.

RESULTSIFN-gamma + 874 SNP was tested successfully for every subject. Frequencies of AA, AT and TT genotype were 67.4%, 19.6% and 13.0% in the intrauterine HBV infection group, and 45.2%, 30.1% and 24.7% in the normal immune children group. A significant difference was found in the frequency distribution of IFN-gamma + 874 genotype between the two groups (chi(2) = 5.102, P = 0.02389). In the intrauterine HBV infection group the AA genotype was more common than in normal immune group.

CONCLUSIONThere is an association between IFN-gamma + 874 SNP and intrauterine HBV infection. This study suggested the possibility that IFN-gamma + 874 SNP might be important in determining an individual's susceptibility to development of intrauterine HBV infection.

OBJECTIVETo investigate the influencing factors on cerebral stroke in Zhangwu county, Liaoning province, a region with high hypertension prevalence rate.

METHODSBy cluster sampling method, 5208 adults ( > 18y. ) from 11 villages of 6 towns were registered. General information, common risk factors of cerebral stroke about these persons was recorded. Blood pressure together with several biochemistry indicators was determined. Data were analyzed by SPSS 10.0 software.

RESULTSStandardized prevalence of cerebral stroke in this region was 3.10%, and the difference between males and females was significant. Prevalence rate was increasing with age. Multiple-factor analysis revealed that the incidence rate of cerebral stroke was related to high blood pressure, high diastolic pressure, pulse pressure, age, high-density lipoprotein cholesterol (HDL-C) and low-DL-C (LDL-C) level with OR values of 95% CI as 2.958 (1.783-4.907), 2.803 (1.934-4.062), 1.154 (1.056-1.261), 1.080 (1.063-1.097), 0.390 (0.235-0.647) and 1.422 (1.008-2.006) respectively.

CONCLUSIONHigh blood pressure, in particular high diastolic pressure, pulse pressure and LDL-C level were main risk factors of cerebral stroke in Zhangwu countryside. However, HDL-C level was a protective factor. No new risk factors were discovered.
