Purpose To investigate the expression of Che-mokine(C-X-C Motif)receptor 5(CXCR5)and its clinico-pathological significance in classic Hodgkin lymphoma(CHL).Methods The expression of CXCR5 was assessed in 33 pa-tients by immunohistochemistry(IHC),and retrospectively ana-lyzed the expression and clinical significance of CXCR5 in the four subtypes of CHL.Meanwhile,10 cases of ALK-positive an-aplastic large cell lymphoma(ALCL)and 10 cases of ALK-neg-ative ALCL were collected as the control group.ResultsThere were 31 cases with CXCR5-positive in all 33 cases(93.94％),including 15/16(93.75％)in nodular sclerosis CHL,12/13(92.31％)in mixed cellularity CHL,2/2 in lymphocyte-rich CHL,and 2/2 in lymphocyte-depleted CHL.The positive ex-pressions of CXCR5 in different immunophenotypes of CHL were as follow,31/33(93.94％)in CD30 positive and PAX5 weakly positive CHL.12/14(85.71％)in CD15 negative CHL,24/26(92.31％)in CD20 negative CHL,10/11(90.91％)in EBER-negative CHL and 5/6 in LMP1-negative CHL.CXCR5 were not expressed in all 20 cases of ALCL.Conclusion The positive expression rate of CXCR5 in CHL is high.When the tumor cells are negative for CD15,LMP1 and CD20 or EBER,CXCR5 also has a high positive expression rate,which is helpful for the diagnosis of CHL.CXCR5 can be used to differentiate CHL from ALCL,especially the cases lacking typical morpholo-gy and immunohistochemistry.

Objective: To investigate the expression of CD24 in prostate cancer (PC) tissues, and explore its relationship with clinicopathological features of PC patients. Methods:Atotal of 40 cases of PC tissues and 36 cases of corresponding para-cacerous tissues resected during surgery at the Department of Urology Surgery, Quanzhou First HospitalAffiliated to Fujian Medical University from February 2016 to March 2019 were collected for this study; in addition, 46 cases of benign prostatic hyperplasia tissues were collected from patients underwent TURP surgery. Flow cytometry was used to detect the expression of CD24 in above mentioned tissues; One-way analysis of variance was used to analyze the relationship between the expression of CD24 and the age, tumor distribution, preoperative serum PSA, postoperative Gleason score, clinical stage and distant metastasis of PC patients. Results: The positive expression rate and MFI (mean fluorensece intensity) value of CD24 in prostate cancer tissues were significantly higher than those in para-cancerous prostate tissues and benign prostatic hyperplasia tissues (all P<0.05); CD24 positive expression rate and MFI value in PC tissues of patients with preoperative serum PSA≥10 ng/ml, postoperative Gleason score≥8 (low differentiation), clinical stage of T4 and distant metastasis were significantly higher than corresponding control group (all P<0.05); The expression of CD24 gradually increased with the progression of postoperative Gleason score and clinical stage ( P <0.05). Conclusions: The expression of CD24 is increased in prostate cancer tissues. The detection of CD24 expression level can help to determine the occurrence, development, invasion and metastasis of prostate cancer, and has potential clinical application value.

Objective To explore the value of multislice CT (MSCT)in the diagnosis of complex congenital heart disease (FCHD)in children.Methods 41 children cases with clinical diagnosis of congenital heart disease were collected randomly.All the children were examined with MSCT and ultrasonic cardiogram(UCG)examination,and 20 cases were examined with cadioangiography(CAG) check.All the cases were confirmed by surgery.The results of Preoperative MSCT,UCG and the CAG heart examination diagnosis were compared with surgical diagnosis results.Results Surgery confirmed 225 deformities and 1 1 5 intracardiac malformations.In the intracardiacmal malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 92.2%,99.1% and 74.4%,respectively;With surgery confirmed 110 heart malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 98.2%,84.5%,96.2%,respec-tively.The combined use of MSCT and UCG confirmed 224 correct diagnoses,the diagnosis coincidence rate reached 99.6%;The check accuracy of MSCT was highter than UCG in congenital heart disease with heart malformations(χ2 =12.962,P <0.05),The differences has statistical significance.Conclusion The check accuracy of MSCT is better in the diagnosis of congenital heart disease.The joint application of MSCT and UCG can obviously improve the accuracy of the diagnosis of congenital heart disease and congenital anoma-lies.

Objective The purpose of this study was to assess the imaging features of newly diagnosed high-grade glioma and the effect of relevant factors such as postoperative radiotherapy and chemotherapy on progression-free sur-vival (PFS) time. Methods A total of 54 patients with recurrent high-grade glioma confirmed by pathology or progressive malignant glioma proved by clinical follow-up were included in this retrospective study from 4 clinical centers. The prog-nostic factors selected included MR image features at initial diagnosis (including the maximum diameter of tumor, peritu-moral edema, degree of enhancement, degree of necrosis and presence of cystic or satellite), postoperative radiotherapy and chemotherapy. Kaplan-Meier method and Cox’s proportion-hazards model were used to analyse the factors influenc-ing the progression free survival (PFS) time. Results The univariate Kaplan-Meier analysis revealed that the degree of peritumoral edema (PTE, P=0.001), degree of necrosis (P<0.001) , degree of enhancement (P<0.001), postoperative radio-therapy (P=0.008) and chemotherapy(P=0.035) were significant factors for PFS. Cox multivariate analysis also showed that the degree of PTE(P=0.019),degree of necrosis (P<0.001) were all significantly correlated with PFS. The less edema or necrosis was associated with the longer PFS. In addition, postoperative radiotherapy (P=0.035) and chemotherapy (P=0.049) were also significantly correlated with PFS. The normative chemotherapy and radiotherapy were associated with longer PFS. Conclusions The PTE and necrosis on preoperative MR images can be used to predict the PFS of glioma af-ter total resection. Adjuvant normative chemotherapy and radiotherapy should be recommend for supratentorial high-grade glioma including those even with MRI confirmed total resection.
