OBJECTIVE:
Aim of the study is to report the unique clinicopathologic feature, treatment outcome and prognostic factors of head and neck hemangiopericytoma (HNHPC).
METHOD:
A retrospective data collection of reported HNHPC cases, in which therapy, follow-up and outcome data were available, was performed from the electronic database of PubMed, Embase, Google scholar, China National Knowledge Infrastructure, Wan Fang and Wei Pu until on December 31, 2013.
RESULT:
A total of 213 HNHPC cases were identified from 122 peer-reviewed articles. The recurrence rate was 24.4% (51/209). The positive surgical margin (OR= 3. 977, P<0. 01) and poor pathologic differentiation (OR=l. 890, P<0. 01) were associated with increased local recurrence. The metastasis rate was 15.8% (22/139). The positive surgical margin (OR=13. 833, P<0. 01), poor pathologic differentiation (OR=4. 661, P<0. 01) and non-surgical treatment (OR=2. 000, P<0. 01) were associated with increased distant metastasis. The mortality rate was 15. 0% (32/213). The tumor size >5. 0 cm in diameter (OR= 2. 860, P<0. 05), positive surgical margin (OR=9. 833, P<0. 01), poor pathologic differentiation (OR=4. 061, P<0. 01) and non-surgical treatment (OR=2. 032, P<0. 01) were associated with worse mortality. The treatment included surgery alone 139 cases, multiple treatments 64 cases and non-surgical treatment 10 cases. The overall survival (OS) of the 213 cases was 85%, and the 3-year, 5-year and 10-year OS were 86%, 78% and 74%, respectively. The 3-year, 5-year and 10-year OS for surgery alone were 95%, 88% and 84%, respectively. The 3- year, 5-year and 10-year OS for surgery plus radiotherapy were 90%, 80% and 80%, respectively. The 3-year, 5- year and 10-year OS for surgery plus chemotherapy were 75%, 25% and 25%, respectively. The 3-year, 5-year and 10-year OS for surgery plus radio-chemotherapy were 67%, 58% and 46%, respectively. There were signifi- cant survival difference in recurrence-free survival (RFS), metastasis free survival (MFS) and OS depending on surgical margins (P<0. 01). RFS, MFS and OS difference were identified depending on pathologic differentiation (P<0. 01). MFS and OS differences were observed on the different treatment modality (P<0. 01). OS differences was observed on the different tumor sizes (P<0. 05). Positive surgical margins was correlated with disease recurrence (HR= 3. 680, P<0.01), while poor pathologic differentiation was correlated with metastasis and death (HR=2. 619, P<0. 05 and HR=3. 188, P<0. 05). The tumor size >5. 0 cm in diameter and non-surgical treatment was correlated with death (HR= 5. 461, P<0. 01 and HR= 8. 563, P<0. 01, respectively).
CONCLUSION
The surgical resection was the mainstream treatment and it was superior to multiple treatments. The tumor size, surgical margins, pathological differentiation and non-surgical treatment were independent prognostic factors.

[ ABSTRACT] AIM: To study the protective effect of ischemia preconditioning ( IPC ) on ischemia/reperfusion ( IR)-damaged myocardium in young and old rats .METHODS: Male Wistar rats aged at 3 months ( young ) and 20 months ( old) were used to establish myocardial IPC model and IR model with the method of Langendorff heart perfusion . The rats were divided into young ischemia/reperfusion ( YIR) group, young ischemic preconditioning ( YPC) group, old ischemia/reperfusion ( OIR) group and old ischemic preconditioning ( OPC) group.Transmission electron microscopy was used to observe the ultrastructural changes of myocardial tissue and myocardial mitochondria .The myocardial infarction area was determined by TTC staining .The lactate dehydrogenase ( LDH) content in coronary effluent fluid and the levels of su-peroxide dismutase ( SOD) and malondialdehyde ( MDA) in myocardial tissues were detected by the method of colorimetry . The levels of nitrated and carbonylated proteins in myocardial tissue were measured by ELISA .The myocardial cell apopto-sis was analyzed by TUNEL assay .The mitochondrial respiratory function and mitochondrial permeability transition pore o-pening induced by calcium load were evaluated by oxygen electrode method .RESULTS: Compared with YIR group , the myocardial infarction area in YPC group was obviously smaller , SOD activity in myocardial tissues increased , LDH activity in coronary effluent fluid and the content of MDA decreased , and the levels of nitrated and carbonylated proteins in the car-diac tissues reduced .In YPC group, the mitochondrial membrane structure appeared intact , cristae of the mitochondria showed close arrangement , and the matrix was compressed under the electron microscope .Myocardial mitochondrial respir-atory control rate , state Ⅲoxygen consumption and the P/O ratio in YIR group all significantly increased , proton leak de-creased, mitochondrial swelling induced by calcium distinctly reduced , and myocardial apoptosis rate declined .No signifi-cant difference of the above indexes between OIR group and OPC group was observed .Compared with YPC group , myocar-dial ultrastructural damage increased clearly , cardiac oxidative stress increased , mitochondrial respiratory function de-clined, and cell apoptosis and necrosis increased in OPC group .CONCLUSION:Ischemic preconditioning has protective effect against myocardial IR injury in young rat hearts , while old rat hearts were less sensitive to ischemic preconditioning , leading to bluntness of cardioprotection with IPC in aging hearts .This may be related to mitochondrial injury and severe cel-lular apoptosis caused by increase of cardiac oxidative stress levels in the aging ischemic preconditioning heart .

Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P<0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.
