Methods： Seventy-seven newly diagnosed prostate cancers were reviewed in the study. All the cases underwent bone scintigraphy, total serum PSA measurement by luminescent immunoassay before operation and were classified according to post-operative pathology diagnosis. We analyzed the correlations of the bone metastasis incidences and different pathological grades or different PSA levels. Results： Bone scans were indicative of metastases in 33 cases （42.86%）. Significantly higher incidence of bone metastasis was observed in patients with poorly differentiated prostate cancer compared with patients with well （X2 = 10.880, P = 0.001 〈 0.05） and moderately （X2 = 6.166, P = 0.013 〈 0.05） differentiated prostate cancers. No significant difference between the well differentiated and moderately differentiated prostate cancers was found （X2 = 0.612, P = 0.434 〉 0.05）. The serum PSA concentration had＇significant correlation with the incidence of bone metastasis. In 26 patients with PSA 〈 20 ng/mL, 5 cases （19.23%） had bone metastasis while 28 of 51 cases （54.90%） with PSA〉 20 ng/mL had bone metastasis. The serum PSA concentration had positive correlation with pathological grades of prostate cancer （r = 0.535, P = 0.01）. Conclusion： Bone scintigraphy plays a great role in the diagnosis of bone metastasis for prostate cancer patients currently. The poorly differentiated prostate cancer and PSA 〉 20 ng/mL most likely suggested the possibility of bone metastasis.展开更多

While, the combination of them can provide exactly objective markers to evaluate prognosis of patients with brain glioma needs to be further studied based on pathological level. OBJECTIVE： To observe the expressions of proliferating cell nuclear antigen and P27 protein in both injured and normal brain glioma tissues and analyze the effect of them on onset and development of brain glioma. DESIGN： Case contrast observation. SETTING： Department of Neurosurgery, the Second Affiliated Hospital of Xi＇an Jiaotong University. PARTICIPANTS： A total of 63 patients with brain glioma were selected from Department of Neurosurgery, the Second Affiliated Hospital of Xi＇an Jiaotong University from July 1996 to June 2000. There were 38 males and 25 females and their ages ranged from 23 to 71 years. Based on pathological classification and grading standards of brain glioma, patients were divided into grade I - II （n=30） and grade III- IV （n = 33）. All cases received one operation but no radiotherapy and chemiotherapy before operation. Sample tissues were collected from tumor parenchyma. Non-neoplastic brain tissues were collected from another 12 non-tumor subjects who received craniocerebral trauma infra-decompression and regarded as the control group. There were l0 males and 2 females and their ages ranged from 16 to 54 years. The experiment had got confirmed consent from local ethic committee and the collection was provided confirmed consent from patients and their relatives. All samples were restained with HE staining so as to diagnose as the brain glioma. While, all patients with brain glioma received radiotherapy after operation and their survival periods were followed up. METHODS： Primary lesion wax of brain glioma was cut into serial sections and stained with S-P immunohistochemical staining. Brown substance which was observed in tumor nucleus was regarded as the positive expressions of both proliferating cell nuclear antigen and P27 protein. Automatic imaging analytic system was used to quantitatively analyze staining results of tumor. MAIN OUTCOME MEASURES： To compare the expressions of proliferating cell nuclear antigen and P27 protein in brain glioma tissues and non-tumor brain tissues and investigate the effect of various sexes, ages, survival periods and severities on the expressions of them in brain tissues. RESULTS： There was no significant difference of sexes and ages in the expressions of proliferating cell nuclear antigen and P27 protein （P 〉 0.05）; however, the expressions of proliferating cell nuclear antigen and P27 protein were milder in non-tumor brain tissues than those in the brain glioma tissues （P 〈 0.05）. Expression of proliferating cell nuclear antigen in brain tissue of grade III- IV severity was stronger than that of grade I - II severity, and the expression in ≥ 5-year survival periods were also stronger than that in 〈 5-year survival periods （P 〈 0.05）. In addition, expression of P27 protein in brain tissue of grade III- IV severity was stronger than that of grade I - II severity, and the expression in ≥ 5-year survival periods were also stronger than that in 〈 5-year survival periods （P 〈 0.05）. CONCLUSION： Abnormal expressions of proliferating cell nuclear antigen and P27 protein in human brain glioma are closely related to onset, development and prognosis of tumor.展开更多

Methods： The pathological diagnosis of glioma and tumor classification was by HE staining, and we use immunohistochemistry method to analyse the level of nNOS in different pathological grade glioma and the expression level of Cyt-c in mitochondria meanwhile. Results： The levels of nNOS were highest in grade Ⅲ tumors, moderate in grade Ⅱ tumors, and lowest different in grade I tumors. There was significant difference of the nNOS levels among different pathological grade tumors （P 〈 0.05）. Furthermore, the similar phenomenon was observed in the expression level of Cyt-c in mitochondria （P 〈 0.05）. Conclusion： The expression level of nNOS and Cyt-c in mitochondria was significantly related to the pathological grade of glioma.展开更多

Outcomes included the duration of castration-resistant prostate cancer-free survival （CFS） and overall survival （OS）. Univariate analyses and log-rank tests were used to identify prognosis indicators and assess univariable differences in CFS and OS in Gleason score （GS） groups. Cox proportional hazards and area under the curves of receiver operator characteristics methods were used to evaluate the predictive efficacy of the 2005 and 2014 ISUP grading systems. Univariate analyses showed that the 2005 and 2014 grading systems were prognosticators for CFS and OS; both systems could distinguish the clinical outcome of patients with GS 6, GS 7, and GS 8-10. Using the 2014 criteria, no statistical differences in patient survival were observed between GS 3 ＋ 4 and GS 4 ＋ 3 or GS 8 and GS 9-10. The predictive ability of the 2014 and 2005 grading systems was comparable for CFS and OS （P = 0.321）. However, the 2014 grading system did not exhibit superior predictive efficacy in patients initially diagnosed with PCa and bone metastasis; trials using larger cohorts are required to confirm its predictive value. To the best of our knowledge, ours is the first study to compare the 2005 and 2014 grading systems in initially diagnosed PCa with bone metastasis. At present, we recommend that both systems should be used to predict the prognosis of patients with metastatic PCa.展开更多

A promising immuno-fluorescence strategy was rationally designed and synthesized by loading ruthenium complex into cervical cancer-targeted DNA-cage, which was well used to realize high-speed and inexpensive diagnosis of clinical cervical cancer tumor tissues avoiding the traditional multi-stage process, thus demonstrating high application potential in clinical pathological grading and surgical judgment. Moreover, it has been finding that Apts-DNA@Ru can enrichment in the tumor region, interestingly, no enrichment in normal cervical cancer tissue. It has the potential to realize the integration of in vivo diagnose and further synchronous treatment in the near future. Thence, this study demonstrates a strategy for integration of cancer-targeted DNA-cage and fluorescent Ru POP as alternative IHC reagents for next-generation more rapid convenient cancer detection.展开更多
