Oral squamous cell carcinoma (OSCC) is a prevalent malignant tumor affecting the head and neck region (Leemans et al., 2018). It is often diagnosed at a later stage, leading to a poor prognosis (Muzaffar et al., 2021; Li et al., 2023). Despite advances in OSCC treatment, the overall 5-year survival rate of OSCC patients remains alarmingly low, falling below 50% (Jehn et al., 2019; Johnson et al., 2020). According to statistics, only 50% of patients with oral cancer can be treated with surgery. Once discovered, it is more frequently at an advanced stage. In addition, owing to the aggressively invasive and metastatic characteristics of OSCC, most patients die within one year of diagnosis. Hence, the pursuit of novel therapeutic drugs and treatments to improve the response of oral cancer to medication, along with a deeper understanding of their effects, remains crucial objectives in oral cancer research (Johnson et al., 2020; Bhat et al., 2021; Chen et al., 2023; Ruffin et al., 2023).

Objective:To investigate the relationship between the changes of default network topology properties of brain function and cognitive function in patients with end-stage renal disease (ESRD).Methods:A total of 31 patients with ESRD were enrolled in the Department of Nephrology, Changzhou Second Hospital Affiliated to Nanjing Medical University from January 2019 to December 2020, and 18 healthy persons were included in the same period as the control group.The cognitive function was evaluated with the Montreal cognitive assessment (MoCA) and trail making tests, and then the subjects were examined by resting-state functional magnetic resonance imaging (rs-fMRI). After preprocessing, the brain functional network was constructed and the topology properities of the network were calculated.The SPSS 20.0 software was used for statistical analysis.Independent sample t-test, chi square test and Pearson correlation analysis were used for data statistics. Results:(1) The score of MoCA in the ESRD group(23.37±1.77) was significantly lower than that in the healthy control group(27.94±1.13)( t=9.537, P<0.001). (2) The levels of Eglobal, Elocal, Cp and Sigma in ESRD group ((0.129±0.025), (0.148±0.040), (0.188±0.046), (1.593±0.650)) were significantly lower than those in healthy control group ((0.160±0.040), (0.212±0.024), (0.276±0.049), (2.004±0.864))( t=3.591, 7.474, 7.058, 2.034, all P<0.05). The Lp value of the ESRD group (8.131±1.905) was significantly higher than that of the control group (6.777±2.150)( t=2.583, P< 0.05). The node efficiency values of bilateral dorsolateral superior frontal gyrus, left middle frontal gyrus, bilateral posterior cingulate gyrus, right hippocampus, left superior marginal gyrus, bilateral angular gyrus and bilateral cuneate anterior lobe in ESRD group ((0.133±0.071), (0.201±0.047), (0.211±0.106), (0.175±0.066), (0.276±0.113), (0.122±0.146), (0.042±0.075), (0.171±0.027), (0.154±0.078), (0.240±0.095), (0.161±0.056))were lower than those in the healthy control group((0.312±0.075), (0.289±0.091), (0.277±0.132), (0.284±0.053), (0.368±0.063), (0.231±0.227), (0.120±0.162), (0.296±0.064), (0.310±0.186), (0.318±0.066), (0.286±0.103))( t=2.107-9.436, all P<0.05). (3)Pearson correlation analysis showed that the node efficiency values of bilateral posterior cingulate gyrus and right hippocampus in ESRD group were positively correlated with the score of MoCA( r=0.36, 0.49, 0.53, all P<0.05). Conclusion:The topological structure of brain functional network is abnormal in ESRD patients, which can affect the cognitive function of patients.

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 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 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 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 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 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.
