Objective To summarize our experience in the diagnosis and treatment of malignant peritoneal mesothelioma(MPM). Methods Clinical data of 10 patients admitted with MPM were analyzed retrospectively. Results The main symptoms of MPM were intraabdominal mass and abdominal pain in these patients; Seven patients were of localized type, 3 cases were of diffused type; Preoperatively 7 cases were misdiagnosed as other intraperitoneal tumor, 9 patients underwent laparotomy and tumor resection for a total 16 times, including once in 4 cases, two times in 3 cases, and three times in 2 cases. Seven patients received curative resection in initial operation. Five patients died within one year, 6 cases within two years, Tumors recurred postoperatively in 4 cases. 1 case is still survival 9 years after. Conclusion Being comparatively rare, MPM is often misdiagnosed, the prognosis is very poor, curative resection sometimes provides a long survival for localized type of MPM, when combined with perioperative comprehensive therapy.

DNA transposon is a kind of factor that is able to translocate gene in its genome, thus offering an efficient method for permanently modifying the genome of mammals. The piggyBac (PB) transposon system has been proven effective in mammalian genomic engineering, including cancer gene discovery, animal transgenesis, in vivo gene delivery as well as in vitro genetic modification like induced pluripotent stem cells. In addition, piggyBac has many desirable features, such as seamless excision of transposons from the genomic DNA and the potential to target integration events to desired DNA sequences. Therefore, the piggyBac translocation system is an ideal genetic tool in the construction of animal models and gene therapy, and we can anticipate that the piggyBac transposon system will play a more and more important role in biomedical research.

Objective To test the expression of serine/arginine rich splicing factor 1(SRSF1)and apoptosis inhibiting factor(Survivin) in prostate cancer,and study their correlation with the pathological features of prostate cancer,so as to put forward the new targets in the treatment of prostate cancer. Methods SRSF1 and Survivin protein was determined in 20 prostate tissue samples including prostate cancer(n=12)and benign prostat?ic hyperplasia(n=8)by immunohistochemical SP method. SRSF1 and Survivin was correlated to pathological features,and both the relevance was analyzed(no related reports at home and abroad). Results The positive expression rate of SRSF1 protein in prostate cancer tissue cells was 76.37± 5.06%,which was significantly higher than that of benign prostatic hyperplasia(11.30%±1.09%,P<0.05);the positive expression rate of Survivin protein in prostate cancer tissue cells was 86.93%±3.21%,which was significantly higher than that of benign prostatic hyperplasia(17.67%±1.99%, P<0.05);SRSF1 and Survivin protein expressed in prostate cancer organizations and were positively correlated to pathological Gleason grading, and there was significant correlation(P<0.05). Conclusion SRSF1 and Survivin protein were highly expressed in adenocarcinoma tissue,which were significantly increased than that of benign hyperplasia of prostate tissue. The positive expression SRSF1 and Survivin protein were positively cor?related to pathological Gleason grading.The expression of Survivin protein was elevated with the expression of SRSF1 protein in prostate cancer. These preliminary evidence indicated that SRSF1 may up?regulate the expression of Survivin,and thus promote the occurrence and development of prostate cancer.

Objective To demonstrate the value of eombined application of prenatal ultrasonography with fetal magnetic resonance imaging(MRI) in the diagnosis of monochorionic muhifetal realformations. Methods Fourteen cases of muhifetal malformations,detected by prenatal ultrasonography,received MRI within 48 h afterwards.All diagnosis were confirmed after delivery or mid-term termination.All imaging results of the 14 cases were retrospectively reviewed. Results Among the 14 cases,there were 7 acardias,5 Conjoined twins and 2 demise of multifetuses.Comparing ultrasound with MRI,we found that:(1)In cases with acardia and demise of multifetusea,ultrasound could diagnose correctly and be an important tool for follow-up,while MRI could demonstrate organs and structures of the acardiac recipient more clearly and detect the secondary changes of brain in the donor and survived fetus.(2)In Conjoined twins,ultrasound was superior to MRI in demonstrating the structure and function of cardiovascular system : and equivalent to MRI in identifying stomach,kidney,bladder and limbs;but inferior to MRI in identifying esophagus,lung,liver and intestinal,especially in the brain. And MRI could demonstrate two fetuses and the relationship between them in COnjoined twins simultaneously. Conclusions Prenatal ultrasonography and MRI have their own advantages and disadvantages in diagnosing monochorionic multifetal malformations.But the combination of prenatal ultrasonography and fetal MRI may be more valuable.

Objective To investigate the expression of endostatin and angiopoietin (Ang)-2 in human ghoma and its significance. Methods The expression of endostatin and Ang-2 were measured by immunohistochemistry and endostatin mBNA by hybridization in situ in 108 cases of brain glioma and 5 cases of normal brain tissues. Results The expression of endostatin (0.0657±0.0038)and Ang-2 (0.0286± 0.0042) were significantly higher in grade Ⅲ-Ⅳ glioma patients than those in grade Ⅰ-Ⅱ ghoma patients (0.0349±0.0048,0.0084±0.0018, respectively) and normal brain tissues (0,0)(P<0.01). The expression of endostatin mRNA were significantly higher in grade Ⅲ-Ⅳ glioma patients (0.0310±0.0041) than that in grade Ⅰ-Ⅱ glioma patients (0.0152±0.0031) and normal brain tissues (0)(P< 0.01 ). Theratio of endo-stalin to Ang-2 was negatively rehted to the grade of glioma (r=-0.810,P <0.01). Conclusion The interaction of endostatin and Ang-2 plays an important role in the invasive growth and malignant development of human glioma, and may be related to the prognosis and the malignant degree of glioma.

Objective To detect the existence of vasculogenic mimicry in hepatocellular carcinoma (HCC). Methods In this study 42 patients with a total of 47 HCC nodules underwent radical resection.Histological and immunohistochemical double staining of CD31 and PAS were applied to observe the existence of vasculogenic mimicry ( VM ). Reverse tanscription PCR (RT-PCR) were applied to study the expression of VE-cadherin, EPHA2 and MMP-2 genes. Results VM was found in 16 of the 42 (38. 1% )HCC cases. The typical forms of VM in the microscope are vessel-like structure formed by tumor cells,without endothelial cells and the PAS-positive looping pattern. The existence of VM in HCC correlates to a higher Edmondson grade, higher capacity of intrahepatic disseminating and poorer tumor-free survival time (P< 0. 05). Comparing the difference of VE-cadherin gene, EPHA2 gene and MMP-2 gene expression between VM positive nodes and in VM negative nodes by RT-PCR method demonstrated that VE-cadherin gene, EPHA2 gene and MMP-2 gene have a more intense expression in VM positive nodes than in VM negative nodes ( P < 0. 05 ). Conclusion VM exists in human hepatocellular carcinoma. VM occurred more frequently in higher malignant HCC and predicts a higher rate of tumor recurrence and poorer prognosis.
