Methods: The serum TSGF was tested in 69 patients with epithelial ovarian cancer, 28 patients with benign ovarian lesion and 61 healthy women. The serum levels of vascular endothelial growth factor (VEGF) and CA125 were determined in patients with epithelial ovarian cancer and in those with benign ovarian lesion. The correlations of TSGF with VEGF and CA125 were investigated. Results: The serum level of TSGF in patients with epithelial ovarian cancer was obviously higher than in patients with benign ovarian lesion and in healthy women (P<0.01). The serum level of TSGF in patients with epithelial cancer was associated with stage and grade. TSGF was highest in stage III, followed by stage IV, and was lowest in stage I-II. The TSGF level was lower in well-differentiated tumors and was higher in poorly differentiated tumor. There were no significant difference among diagnostic value of TSGF, VEGF, and CA125 in differentiation between epithelial ovarian cancer and benign ovarian lesion (P>0.05). The serum level of TSGF and VEGF and CA125 in patients with epithelial ovarian cancer showed positive correlation (P<0.01, P<0.05, respectively). Conclusion: There is no marked difference in diagnostic value among TSGF, VEGF and CA125. TSGF has a certain value in diagnosis of epithelial ovarian cancer, and is helpful to distinguish epithelial ovarian cancer from benign ovarian lesion.展开更多

Biochemical colorimetric assay were used to detect the serum TSGF level. Blood samples were collected at the time of initial diagnostic evaluation,before each chemotherapy session,and at follow-up visits. The serum TSGF level in dogs with malignant tumors,benign diseases,non-tumor diseases and healthy dog were 67. 3 ± 22. 1 U/mL,57. 3 ± 7. 58 U/mL,60. 2 ± 14. 2 U/mL and 54. 6 ± 3. 21 U/mL,the first group was statistically significant higher than the latter (P < 0. 05). 56. 6% malignant patients exceeded the upper limit of the normal reference range (61 U/mL). The samples were classified to groups according clinic stage. The TSGF level from malignant tumor groups were stage I 56. 8 ± 5. 93 U/mL. stage II 66. 7 ± 25. 7 U/mL,stage III 75. 6 ± 22. 7 U/mL and stage IV 73. 9 ± 29. 6 U/mL. Excluding stage I, the TSGF level of all stages are statistically significant higher than healthy group,respectively,the stage III was also statistically significant higher than stage I. Further follow-up study indicated that in entirely insect group,the TSGF level decreased after treatment and kept in low level. In the partly insect group,although the TSGF activity decreased in a short term after surgery,the TSGF level would increase again and kept in high level. From this fact we considered that TSGF level is expected to be a newly potential biomarker in screening neoplastic diseases in veterinary and a monitoring factor for predicting relapse.展开更多

While these innovations deliver operational improvements, the heightened interconnectivity introduces significant cybersecurity challenges, particularly within military logistics, where mission-critical operations and life-safety concerns are paramount. This paper examines these unique cybersecurity requirements, focusing on advanced persistent threats, supply chain poisoning, and data breaches that could compromise sensitive operations. The study proposes a hybrid cybersecurity framework tailored to military logistics, integrating resilience, redundancy, and cross-jurisdictional security measures. Real-world applicability is validated through simulations, offering strategies for securing supply chains while balancing security, efficiency, and flexibility.展开更多
