1.Prognostic factors of the invasion and metastasis of gastric cancer and their applications in targeted therapy
International Journal of Surgery 2011;38(10):707-710
Invasion and metastasis are critical determinants on cancer morbidity.Genes and molecules participating in these steps have been demonstrated as potential prognostic factors.Growth factors and their receptors,cell-cycle regulators,cell-adhesion molecules and m trix-degrading enzymes are potentially used as prognostic factors.However,increased understandings for molecular mechanisms underlying carcinogenesis and its implementation in the treatment of gastric cancers have recently been focused on the development and incorporation of targeted agents with chemotherapy.

Objective To study the expression, distribution and significance of C2 gene in hepatocellular carcinoma (HCC) and gastric cancer tissue. Methods ABC immunohistochemical method was used to detect the expression of C2 protein in 60 samples of HCC tissue and 58 samples of gastric cancer tissue, and Western blot technique was used to detect the expression of C2 protein in 10 samples of HCC tissue and pericancerous tissue. Results 1. Expression of C2 protein in HCC tissue: in 60 samples of HCC and 42 samples of pericancerous tissue, the positivity rate of C2 protein was 27.3% and 83.3%, respectively. The positivity rate of C2 protein was significantly higher in pericancerous tissue than that in HCC tissue ( P

Objective To evaluate the therapeutic effect of 89 Sr internal radiotherapy on multiple-bone metastasis of cancer. Methods Forty-nine cancer patients with multiple-bone metastasis received 89 Sr internal radiotherapy. The pain control effect, life quality improvement, change in levels of blood calcium and serum alkaline phosphatase (ALP), and side effects were analyzed respectively. Results The total effective rate of pain control was 77.6 %. The life quality was improved obviously. The levels of blood calcium and ALP were decreased. No obvious side effects were found during the treatment. Conclusion 89 Sr internal radiotherapy had a good therapeutic effect on multiple-bone metastasis of cancer.

ObjectiveTo observe the effection of different interventions of group B streptococcus (GBS) infection in gestation period.MethodsOne hundred and seventeen cases with GBS infection were obtained from 1885 pregnant women,who were got routine prenatal examination at 34 to 37 weeks of pregnancy,and drug seeitivity test of secretions which were taken from under paragraph 1/3 of vagina,and divided into treatment group (91 cases) and untreatment group (26 cases).The treatment group was divided into treatment group one (47 cases) and treatment group two (44 cases).Treatment group one was treated with oral antibiotics for 7 days after diagnosis,treatment group one and two were treated with postpartum antibiotics intravenous infusion once every 4 hours in labor.Comparison of maternal and fetal outcomes.ResultsThe GBS infection rate was 6.2% (117/1885).The morbidity of premature delivery,premature rupture of membrane and neonatal infection of treatment group [ 5.5% ( 5/91 ),13.2% ( 12/91 ),5.5% (5/91 ) ]were lower than those of untreatment group [ 19.2%(5/26),30.8%(8/26),23.1%(6/26) ](P < 0.05).The morbidity of premature dehvery and premature rupture of membrane of treatment group one[ 0,6.4% (3/47)]were lower than those of treatment group two[ 11.4% (5/44),20.5% (9/44)](P < 0.05).Conclusion Anti-GBS treatment can improve the outcomes of mothers and infants,especially early anti-GBS treatment during the period of pregnancy.

Through summarization on published literatures on allergic rat model in recent 20 years, domestic current research status and trend were analyzed. Some insights were provided on how to build a standard process for modeling and post-modeling evaluation. “Allergic rhinitis,” “rat model of allergic rhinitis”, or “animal experiment” was used as search terms. Related published articles were searched in the CNKI database from August, 1993 to October, 2013. Documents and data, including modeling method, drug dose, modeling cycle, model assessment described in the articles were extracted, summarized and quantitative analyzed. The results showed that 208 valid articles were included in this study. SD rat was used as animal model. Ovalbumin plus aluminum hydroxide were used as adjuvant sensitizing agents. Intraperitoneal injection plus nasal stimulation were the most commonly used modeling method. Behavioral evaluation scale score was used as the main evaluation index. It was concluded that currently there were many methods for allergic rhinitis animal modeling domestically. The post-modeling evaluation was relatively single. It was urgent and necessary to establish the standard process for modeling and post-modeling evaluation for allergic rhinitis animal model.
