With the vigorous development of computers and internet, the construction of the information management system for Occupational Health Technical Service (OHTS) institutions in China has achieved impressive progress. But for the management of OHTS institutions, there are relatively few systems that can fully explore and utilize OHTS information. Base on this background, in light of the actual situation of the OHTS institution in Henan Province, an OHTS Information Management System was developed under the Java Spring Boot framework, with a MySQL database and a B/S multi-tier architecture. The platform integrates a vertical three-level network of ″provincial-municipal-county/district″ and a horizontal network involving health commissions, disease prevention and control bureaus, Centers for Disease Control and Prevention (occupational disease prevention and treatment institutes), and OHTS institutions. The system includes five core modules: dynamic management of institutional and personnel qualifications, full-process project supervision (including five categories of technical services such as pre-evaluation and control-effectiveness evaluation), multidimensional decision analysis (including eight statistical indicators of institutional distribution, equipment allocation, and occupational hazard factors), rapid generation and automated submission of various reports, and early warning and intelligent supervision. The system has been implemented in 61 OHTS institutions in Henan Province, improving the ″off-site supervision rate″ of supervision department and promoting the standardization and digital transformation of occupational health services.

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.

Objective: To investigate differentially expressed protein profiles in B16-F10 grafted melanoma and its metastasis in the lung in order to identify molecular markers of melanoma metastasis. Methods: Differentially expressed proteins in B16-F10 grafted melanoma and its metastatic lesion in the lung were isolated and identified by fluorescence two-dimensional differential gel electrophoresis(2D-DIGE)coupled with matrix assisted laser desorption ionisation time-of-flight mass spectrometry(MALDI-TOF-MS).Some of identified proteins were further confirmed by Real-time PCR analysis. Results: High resolutional images of differential gel electrophoresis were obtained and 9 of 30 differentially expressed proteins (IRatiol≥2,P<0.01)were identified by MALDI-TOF-MS.The expression of Myoglobin(MB),vimentin(VIM),phosphoglycerate kinase 1(PGK1),Triosephosphate isomerase(TPI or TIM),heavy-chain binding protein(BiP),α-enolase,β-actin,γ-actin,and laminin-binding protein were up-regulated in the experimental group compared with the control group.These proteins were involved in the cytoskeletal formation,glycolysis and so on.Real-time PCR analysis showed up-regulation of mRNA expression of PGK1 and TPI in the experimental group(P=0.001 and 0.003),which was in consistent with the resuits of proteomic analysis. Conclusion: A variety of abnormally expressed proteins contribute to the metastasis of mice melanoma.Glycolytic enzymes PGK1 and TPI may be involved in this process.

Objective: To study the prognostic significance of the subtype of SYT-SSX fusion gene, E-cadherin, β-Catenin and clinicopathologicel parameters for the metastasis of synovial sarcomas. Methods: A total of 98 synovial sar-coma patients with complete clinical and follow-up data were reviewed. RT-PCR was used to detect the subtype of SYT-SSX fusion geneo The expression of E-cadherin and β-catenin was detected by immunohistochemistry. Univariate and multivariate analyses were performed to analyze the influence of the above factors and clinicopathological parameters on the metastasis free survival to explore the factors affecting the metastasis of synovial sarcoma. Results: Of all the pa-tients, 69.4% (68/98) had metastasis during follow-up. The median metastasis free survival was 48 months. The metastasis free 1-, 2-, 3-, 4-, and 5-year survival rate after surgery was 97.5%, 75.5%, 63.5%, 54.0%, and 48.5%, respectively; 31.6% (31/98) patients were found with SYT-SSX1 and 68.4% (67/98) patients with SYI-SSX2. The positive rate of E-cadherin ex-pression was 38.8% (38/98), the positive rate of β-catenin expression was 39.8% (39198) on cellular membrane and 53.1% (52/98) in cellular nucleus/cytoplasm. Univariate analysis showed that age (P=0.003), mitotic figure (P=0.002), histological grade (P=0.001), the subtype fusion gene of SYT-SSX (P=0.014), E-cadherin expression (P=0.015) and β-catenin expres-sion on cellular membrane (P=0.020) were significantly correlated with metastasis free survival of synovial sarcoma pa-tients. Sex (P=0.190), tumor location (P=0.105), tumor size (P=0.180), histological type (P=0.354), necrosis (P=0.451), β-catenin expression in cell nucleus/cytoplasm (P=0.911), radiotherapy (P=0.193), and chemotherapy (P=0.249) had no sig-nificant correlation with metastasis free survival of synovial sarcoma patients. Multivariate analysis revealed that the sub-type of SYT-SSX1 fusion gene (RR=2.505, P=0.003), negative expression of E-cadherin (RR=3.282, P=0.000), patient age (RR=2.157, P=0.004), and grade Ⅲ (RR=1.784, P=0.030) were independent risk factors for metastasis of synovial sarco-ma. Conclusion: The subtype of SYT-SSX, expression of E-cadherin, histological grade and the age of patients are impor-tant factors for evaluating the metastasis and prognosis of synovial sarcoma.

Objective: To study the prognostic significance of cell proliferation and apoptosis, MVD and clinicopathologi-cal parameters for the recurrence of synovial sarcoma. Methods: We analyzed the clinical and follow-up data of 56 synovial sarcoma patients without metastasis. RT-PCR was used to detect the subtype of SYT-SSX fusion gene. The expression of Ki67 and MVD was detected by immunohistochemistry. Univariate analysis was employed to analyze the influence of the above factors and clinicopathological parameters on the recurrence free survival and to explore the influencing factors for the recurrence of synovial sarcoma. Results: Of all the patients, 73.2% (41/56) had recurrence during the follow-up. The median recurrence free survival was 19.5 months. The recurrence free 1-, 2-, 3-, 4-, and 5-year survival rates after surgery were 45.0%, 41.0%, 34.0%, 28.0%, and 28.0%, respectively. Ki-67 labeling index (LI) was 19.98%±11.64% and MVD was 51.83±21.92 per ×400. There was no significant difference in apoptotic index (AI) between the two groups (P=0.607). Χ~2 analysis showed that histological type (P=0.000) and MVD (P=0.045) were significantly correlated with the recurrence of sy-novial sarcoma. Univariate analysis showed that Ki67 LI (P=0.009), histological type (P=0.012) and radiotherapy (P= 0.014) were significantly correlated with the recurrence free survival of synovial sarcoma patients. Sex (P=0.015), tumor lo-cation (P=0.411), tumor size (P=0.801), necrosis (P=0.486), MVD (P=0.454), chemotherapy (P=0.272), and apoptotic grade (P=0.899) were not correlated with the recurrence free survival of synovial sarcoma patients. Multivariate analysis re-vealed that higher expression of Ki67 (RR=1.944, P=0.045), radiotherapy (RR=0.482, P=0.04), and histological type (RR= 0.207, P=0.031) were independent risk factors for the recurrence of synovial sarcoma. Conclusion: The expression of Ki67, radiotherapy and histological type are important factors for evaluating the recurrence and prognosis of synovial sarcoma.
