Objective To investigate the expression of CD24 and FAK in the invasive breast ductal carcinoma tissues and their clin-ical significance. Methods Tissues were obtained from 86 patients with breast carcinoma and 30 non-cancer specimens. The expression of CD24 and FAK was detected by immunohistochemical technique (ElivisionTMPlus) and their correlation with tumor clinicopathological char-acters was analyzed. Results The positive rate of CD24 and FAK expression in 86 cases of breast carcinoma was 87.2% (75/86) and 72.1% (62/86) respectively, which was significantly different from that in control group(P<0.01). Expression of CD24 was significantly correlated with axillary lymph node metastasis(P<0.01). Expression of FAK was correlated with histopathologic grade, axillary lymph node metastasis and clinical stage (P<0.05). There was a positive correlation between the expressions of CD24 and FAK in breast carci-noma tissues (rs = 0.222, P < 0.05). Conclusion Expression of CD24 and FAK are closely correlated with the development of breast carcinoma and there is a markedly positive correlation between CD24 and FAK expression. These indexes can be helpful in understanding the biological behaviors and predicting the prognosis of breast carcinoma.

Objective To study the effect of postoperative adjuvant transarterial chemoembolization (TACE) on prognosis of patients after radical resection of primary hepatocellular carcinoma.Methods A retrospective analysis was conducted on 311 patients with primary hepatocellular carcinoma treated from 2002 to 2008 in Quanzhou First Hospital affiliated to the Fujian Medical University.Utilizing the COX regression model and the Kaplan-Meier analysis,the effects of adjuvant TACE on prognosis of both the high risk group (n =76) and the low risk group (n =91) with tumor ≤5 cm,as well as both the high risk group (n =65) and the low risk group (n =78) with tumor ＞ 5 cm were determined.The low risk group was defined as patients with a single tumor and without vascular invasion,while the high risk group was defined as patients with multiple tumors or with vascular invasion.Results The postoperative overall survival rate of the high risk group who underwent postoperative adjuvant TACE with tumor ＞ 5 cm was higher than that of the high risk group who did not undergo postoperative adjuvant TACE (P ＜ 0.05).However,whether or not postoperative adjuvant TACE was given had no effect on prognosis in the other subgroups of patients (P ＞ 0.05).Conclusion Postoperative adjuvant TACE was beneficial to the high risk group of patients with tumor ＞ 5 cm after radical resection of primary hepatocellular carcinoma.

Objective To study the significance of CD24 protein expression in esophageal squamous cell carcinoma and its relationship with clinical pathological parameters and clinical prognosis.Methods The expression of CD24 protein was studied in 90 esophageal squamous cell carcinoma samples by EnVision immunohistochemical analysis and to study relationship of CD24 with clinical pathological parameters and prognosis.Results The expression of CD24 in esophageal squamous cell carcinoma was significantly higher than that in adjacent normal tissue (x 2 =0.832,P ＜ 0.05).The expression of CD24 was not related with the age of patien,sexuality and the histologic grade (x2 =0.741,0.361,0.930,8.858,all P ＞ 0.05),but with clinical stage of the cance (x2 =10.804,P =0.005),lymph node metastasis (x2 =12.349,P =0.000) and depth of tumor invasion (x2 =13.94,P =0.007).Significant difference in survival between the different CD24 expression group,the OR (95 ％ CI) values were 2.105 (61.022-69.273),2.313 (55.108-64.176),1.286 (32.388-37.429),the survival of patients with strong expression of CD24 was inferior to that of weak expression of CD24,depth of tumor invasion and lymph node metastasis were independent prognostic factors of esophageal squamous cell carcinoma.Conclusion CD24 may be related to the malignant process of esophageal squamous cell carcinoma.Overexpression of CD24 indicates poor prognosis in esophageal squamous cell carcinoma patients.CD24 may become a new independent prognostic factor for esophageal squamous cell carcinoma.

OBJECTIVE: To explore and summarize the operation method and operation stage for cochlear implant with chronic suppurative otitis media, to provide the clinical reference for cochlear implant with chronic suppurative otitis media. METHOD: The clinical data of 6 cases of cochlear implant with chronic suppurative otitis media from Jun 2006 to Mar 2009 in our hospital was analyzed retrospectively. The operation stage. surgical skill, possible risk and prognosis was analyzed and summarized. RESULT: 3 of 6 cases received single stage subtotal petrosectomy and cochlear implant. 3 of 6 cases received subtotal petrosectomy, they received staged cochlear implant 1 to 6 months later. No complications occurred, all of the cochlear implanted had good open set speech perception. CONCLUSION Staged operation was the first choice for cochlear implant with chronic suppurative otitis media. Single stage operation took potential risks, it should be done cautiously. The key points for the operation was the clearance of the pathological tissue totally, this required good surgical skill and operation instrument.

Objective To compare the prognostic value of different inflammation-based prognostic scores and Tumor Node Metastasis ( TNM) stage for patients undergoing radical resection of pancreatic cancer with the routine TNM stage in clinical practice.Methods Clinical data of 185 patients with pancreatic cancer who underwent radical surgery were retrospectively analyzed.Based on the inflammation-based prognostic scores ( Glasgow prognostic score ( GPS ) , neutrophil lymphocyte ratio ( NLR ) , platelet lymphocyte ratio ( PLR) , prognostic nutritional index ( PNI ) and prognostic index ( PI ) ) before surgery, univariate and multivariate analyses were used for identifying influential factors on patients′survival.Homogeneity of different scoring systems was compared using likelihood ratio chi-quare test, and linear trend chi-square test, and receiver operating characteristic ( ROC) curve were performed to compare the differentiating ability and single trend of the selected scores with those of routine TNM stage.Results In univariate analysis, preoperative weight loss, serum C-reactive protein, serum albumin, CA19-9, radical surgery, NLR, PLR, GPS, PI, PNI and TNM stage were all significantly associated with patients′overall survival after surgery (P<0.001).In multivariate cox risk model analysis, TNM stage, radical surgery, GPS, NLR, PLR, PI and PNI were independent risk factors for patients′survival after surgery.ROC curve showed that GPS had higher AUC than other scoring systems, but TNM stage had the highest AUC.The homogeneity, differentiating ability and single trend of GPS were higher compared to other inflammation-based prognostic scores, but those of TNM stage were the highest.Conclusions The inflammation-based prognostic scores like GPS, NLR, PLR, PI and PNI were independent prognostic factors for pancreatic caner patients′survival after surgery, and the prognostic value of GPS was superior to that of NLR, PLR, PI and PNI.

Objective:To evaluate the objective imaging markers of cognitive impairment in patients with end-stage renal disease by MRI intravoxel incoherent motion.Methods:A total of 40 patients with ESRD were enrolled in the Department of Nephrology, Changzhou Second Hospital Affiliated to Nanjing Medical University from January 2019 to August 2020, and 24 healthy controls were prospectively enrolled at the same time.All subjects performed with MRI scan were collected, and the slow apparent diffusion coefficient (ADC slow) of the corresponding brain regions were obtained .The cognitive function was evaluated by the Montreal cognitive assessment scale (MoCA). Two-sample t test was used to analyze the difference of ADC slow and cognitive score between the two groups.Pearson correlation analysis was performed among the cognitive function score of end-stage renal disease and ADC slow value. Results:(1) The score of the intelligence test scale in the ESRD group (23.30±1.76) was significantly lower than that of the healthy control group (27.92±1.00) ( P<0.01). The ADC slow values of bilateral frontal lobe, hippocampus, and insula brain areas (respectively(0.648±0.035), (0.633±0.043), (0.762±0.043), (0.756±0.042), (0.792±0.048), (0.776±0.054))in the ESRD group were significantly higher than those in the healthy control group ((0.600±0.039), 0.610±0.037, (0.725±0.059), (0.711±0.054), (0.740±0.063), (0.716±0.051)) ( P<0.01). (2) Pearson correlation analysis showed that the ADC slow values of bilateral insula and right hippocampus in the ESRD group were negatively correlated with MoCA scales ( r=-0.38, -0.38, -0.66, all P<0.05). Conclusion:ADC slow value in IVIM can better reflect the changes of cognitive function impairment in ESRD patients.

Objective To investigate the function and characteristics of histamine receptors on the hemopoietic progenitor cells.Methods BDF1 mice (both male and female), inbred at our university, aged 8-12 weeks, weighing 20-24 g, were used in this study. Bone marrow cells were incubated for 1 hour at 37℃ with 2-AT (H1 receptor agonist) or impromidine (H2 receptor agonist) alone, or in combination with the antagonists pyrilamine or cimetidine respectively. Control experiment was performed in Dulbecco's modified Eagle's Medium (DMEM) alone. Cells treated with different drugs were performed by colony forming unit-granulocyte-macrophage (CFU-GM) and colony forming unit-megakaryocyte (CFU-Meg) assay.Results When bone marrow cells were treated with 10-8 mol/L to 10-5 mol/L of 2-thiazolylethylamine (2-AT) which had no influence on CFU-GM and CFU-Meg proliferation, 10-8 mol/L to 10-5 mol/L of impromidine could increase the number of CFU-GM and CFU-Meg colonies. The effects of H2 receptor agonists on CFU-GM, CFU-Meg could be antagonized by H1 receptor agonist.Conclusions Our findings suggest the existence of histamine H1 and H2 receptors on the hemopoietic progenitor cells and the antagonism between two different histamine receptor subtypes on the proliferation of CFU-GM and CFU-Meg.
