OBJECTIVE:To observe the effects of thalidomide in the growth of the human ovarian cancer cells (OVCAR-3) and HCT-8 as well as the angiogenesis in tumor tissue through building a model of heterograft of nude mice with human tumors. METHODS: After implanting human tumors in nude mice for modeling, the inoculated nude mice were intragastrically administered different dose of thalidomide, with tumor growth condition observed and compared with control group. The diversity of microvessel density(MVD) in tumor tissue was detected by immunohistochemistry. RESULTS: Middle and high dose thalidomide could significantly inhibit the growth of OVCAR-3 human tumor in nude mice(P

Objective To explore the related factors of the relapse of schizophrenics in unwell developed economic areas.Methods To analyze 718 schizophrenics by single and multiple stepwise regression analyses to explore whether relapse of schizophrenia was related to those factors.Results 2.8％ experienced one time relapse, 14.2％ experienced two times relapse and 83％ three times. The rate of schizophrenic relapse was in turn correlated with treatment compliance, treatment intervention, marriage, clinical features, psychological stress,social support, the way of forming disease, medical expenses and condition of access to medical care. Conclusions More attention should be paid to the factors causing schizophrenic relapse and wider measures of prevention and treatment should be taken.

Objective To discuss the activity of Toxoplasma gondii and its impact on fetus during pregnancy.Methods Sixty -eight pregnant women whose IgG was positive and IgM was negative for anti - Toxoplasma gondii antibodies were chosen.Their serum and umbilical blood were tested for IgG,IgM,CAg (by ELISA) and DNA (by PCR) of Toxoplasma gondii.The infections of placental samples were tested by the direct smear,homogenate smear and PCR.Results There were 28 positive cases of Toxoplasma gondii IgG antibodies in cord blood,and the vertical transmission rate of IgG in placenta was 41.2%.There were 6 positive cases of Toxoplasma gondii DNA in cord blood,and the incidence of intrauterine infection was 8.8%.There were 9 positive cases of Toxoplasma gondii DNA in placental tissues,and the incidence of intrauterine infection was 13.2%.Conclusions Past Toxoplasma gondii infection during pregnancy may lead to vertical transmission between the mother and infant.

Some specific markers are useful of separating and identifying gastric cancer stem cells.They are including gastric stem cells,general tumor stem cells and mesenchymal tissue stem cells.At present,more and more new biomarkers are discovered besides familiar CD133 and CD44.Combined detection helps to separate pure gastric cancer stem cells and promote the therapy of gastric cancer.

OBJECTIVE: To evaluate the status quo and trend of the application of narcotic drugs and psychotropic substances Ⅰ in Yangzhou area.METHODS: The narcotic drugs and psychotropic substances Ⅰ used in 124 hospitals of Yangzhou from 2005 to 2007 were analyzed in respect of consumption sum,DDDs and DDC etc. RESULTS: A total of 13 kinds of narcotic drugs and 4 psychotropic substances Ⅰ were used in the 124 hospitals,and the consumption sum of these drugs increased year on year.Fentanyl remained at the first place in terms of DDDs in each year,Remifentanil Hydrochloride for Injection and Sufentanil Citrate showed an obvious increasing trend in consumption,but the consumption of Bucinnazine Hydrochloride Injection(Tablet),Triazolam and Buprenorphine Hydrochloride Injection decreased to a large extent.CONCLUSION: The use of narcotic drugs and psychotropic substances Ⅰ in the 124 hospitals in Yangzhou area was basically in line with the standard.However,the DDDs of Pethidine Hydrochloride Injection had all along dominated the front place suggesting that clinicians should attach great importance to the standard treatment of cancer pain.

Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.

Objective To conclude nursing experience of second anastomotic leakage after radical gastric cancer surgery. Methods The present study compared the differences of clinical symptoms between these two anastomotic leakages, and found a way to detect latent anastomotic leakage with an unobvious abdominal sign accurately and opportunely. The study also intervened in the patient′s observation, psychological condition, peritoneal irrigation and nutritional support after surgery. Results The patients were discharged from the hospital after cured with well controlled condition. Conclusions In order to make an early detection and treatment of the second anastomotic leakage, nurses should not only observe the abdominal sign, but also observe the systematic poisoning and concomitant symptoms.
