Objective: To investigate the relationship of loss of P16 expression with biologlical behaviors and prognosis of gastrointestinal stromal tumors(GISTs). Methods: The expression of P16 protein and mRNA was detected in GISTs tissues by immunohistochemistry,Western blot and RT-PCR.The prognosis was evaluated through follow up. Results: The expression rates of P16 protein and mRNA in GISTs were 53.8%(21/39，Frozen tissue)，51.3%(20/39，Frozen tissues)and 51.4%(37/72，Paraffin-embedded tissues)，respectively.The expression of P16 was significantly different among GISTs of different aggressive risk(P<0.05).With the incease of aggressive risk，the expression of P16 was deceased.The expression of P16 was negtively correlated with Ki-67 and patient survival(P<0.05). Conclusion: The loss of P16 expression has a positive correlation with the infiltration and progression of GIST.Detection of P16 protein and mRNA is helpful for the evalutaion of biological behaviors and prognosis of gastrointestinal stromal tumors.

Objective To explore the relationship between the endovascular aortic repair (EVAR)in patients with abdominal aortic aneurysm (AAA) and postoperative systemic inflammatory response syndrome (SIRS).Methods In this study,93 AAA patients undergoing EVAR were enrolled.Analysis was performed to evaluate the incidence of SIRS during peri-operation period.Logistic multiple regression analysis was performed to determine the parameters predicting SIRS.Results The incidence of SIRS was 58.1％.Aneurysm size,mural thrombus,iliac artery lesion,number of stent,operating time,volume of contrast agent,blood loss and length of stay were all significantly correlated with SIRS (P ＜ 0.05).In a logistic regression model,history of kidney disease or operation,aneurysm size,ruptured aneurysm and number of stents were strongly and independently associated with SIRS.Conclusions SIRS is common in AAA patients after EVAR.Optimizing treatment strategies avoiding risk factors for SIRS benefits AAA patients.

The non-random distribution of atherosclerosis was related to local hemodynamic environment. The stabilization of endothelium was important in this process. We studied the effect of magnitude of shear stress on proliferation of endothelial cells. It was shown the proliferation of endothelial cells was inhibited by shear stress, and was related to the magnitude of shear stress. A parallel plate sudden-expansion flow chamber was constructed, and the effect of flow pattern was also studied. It was shown the inhibition effect produced by shear stress was decreased in this chamber.

Objective To study the main subtypes messenger ribonucleic acid(mRNA) and the basal enzyme activity of phosphodiesterase (PDE) in rat pulmonary microvascular endothelial cells (PMVECs) through the examination mRNA expression and activity of PDE in vitro. The data were offered to reveal the relationship between PDE distributions, activity change and to accumulate data for the possibility of drug regulation of its functional alteration. Methods The cells were cultured with tissue-sticking method;the gene expression of PDEs was detected by reverse transcript polymerase chain reaction (RT-PCR), and the activity of PDEs was calculated by cyclic nucleotides content change examined with high performance liquid chromatogram (HPLC) before and after the PDE reaction( n ＝3). Results The PMVECs identified by cell immunofluorescence with polyclonal antibody of CD31 were dissociated and cultured, mRNAs of PDE1A, 1C, 2A,3A, 3B, 4A, 4D, 5A, 7A, 7B, 8A, 8B, 9A, 10A,11A were expressed in PMVECs, but there was no mRNA of PDE1B expressed in PMVECs. cAMP/cGMP-PDE in the extent of 5-20μl had a good linear correlation with its activity. Conclusion There are 17 kinds of PDE gene expression existing in PMVECs which contain of the basic enzyme with a higher activity.

OBJECTIVE: To observe effects of three-dimensional EH composite template on repairing cranial bone defect. METHODS: A total of 53 inpatients were analyzed retrospectively at the Department of Neurosurgery, Taixing People's Hospital from July 2004 to May 2007, comprising 31 males and 22 females, aged 19-68 years. They were in accordance with cranial repairing indication. Reasons for skull defect: traumatic brain injury (41 cases), hypertension (7 cases), intracranial cancer (3 cases), intracranial aneurysm (2 cases). Thirteen patients developed bilateral cranial defect. The defect region: frontal (5 slices, comprising 2 with severe orbital part defect), temporal (9 slices), frontotemporal (42 slices), temporoparietal (3 slices), parietoocipital (4 slices),frontoparietal (3 slices). The smallest single-chip defect size was 4 cm × 6 cm, and the largest one was 12 cm×18 cm. All the patients were mended by three-dimensional EH composite template using spiral CT (≤5 mm thickness) scanning, CAD three dimensional reconstruction, quickly modeling technique. Infection of incisional wound, rejection and complications were observed. RESULTS: A total of 53 patients were followed up, with an average follow-up period of 18 months, and all of them were satisfied with the shapes (100%). Mild collection of the fluid under the scalp was found in 2 cases 4 days and 1 week following surgery, and disappeared after suction and pressure dressing. No other frequent complications were observed after cranioplasty. CONCLUSION: Three-dimensional EH composite template is an ideal material for cranial bone defect, because of its good biocompatibility, easy operation, good postoperative shape and less complications.

Objective This study was conducted to investigate the clinical outcomes and safety of percutaneous coronary intervention (PCI) to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction. Methods Twenty-seven patients with severe left ventricular systolic dysfunction (ejection fraction≤35%) undergoing PCI were included. All the patients received PCI only to the single-opened vessel lesion under the conditions of: (1) There were limitations to open chronic total occlusion (CTO);(2) Single-opened vessel lesion was not calcified and tortuous. Clinical outcomes, including success rate of PCI, changes of symptoms in-hospital, brain natriuretic peptide (BNP) and left ventricular ejection fraction (LVEF) pre-and one week post-PCI, the major adverse cardiac events (MACE, including death, myocardial infarction and target vessel revascularization) at 30-days after discharged were observed. Results The success rate of PCI was obtained in all 27 patients(100%), and all the patients received drug eluting stent implantation. The symptoms improvement occurred in all patients and the NYHA class improved from grade Ⅳto grade Ⅲin 22 patients(81.5%) in-hospital. Significant differences were noted in the mean BNP and LVEF between pre-PCI and one week post-PCI, BNP[(2699.6±1104.7) pg/ml vs. (737.0 ± 261.7) pg/ml, P<0.05],LVEF[(26.9±5.7)%vs. (36.0±3.41)%, P<0.05)]. No MACE happened in-hospital and at 30-days follow up. Conclusions PCI only to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction under the condition of limitations to open CTO is safe and can significantly improve clinical outcomes in-hospital and at 30-days follow up, but it must be emphasized that single-opened vessel lesion not with obvious calcification and tortuosity.
