OBJECTIVES: To evaluate the performance of different multi-modality fusion models for predicting radiation-induced oral mucositis (RIOM) following radiotherapy in patients with nasopharyngeal carcinoma (NPC). METHODS: We retrospectively collected the data from 198 patients with locally advanced NPC who experienced RIOM following radiotherapy at the Affiliated Tumor Hospital of Guangzhou Medical University from September, 2022 to February, 2023. Based on oral radiation dose-volume parameters and clinical features of NPC, basic classification models were developed using different combinations of feature selection algorithms and classifiers and integrated using a multi-criterion decision-making (MCDM)-based classifier fusion (MCF) strategy and its variant, the H-MCF model. The basic classification models, MCF model, the H-MCF model with a single modality or multiple modalities and other ensemble classifiers were compared for performances for predicting RIOM by assessing the area under the ROC curve (AUC), accuracy, sensitivity, and specificity. RESULTS: The H-MCF model, which integrated multi-modality features, achieved the highest accuracy for predicting severe RIOM with an AUC of 0.883, accuracy of 0.850, sensitivity of 0.933, and specificity of 0.800. CONCLUSIONS Compared with each of the individual classifiers, the multimodal multi-classifier fusion algorithm combining clinical and dosimetric modalities demonstrates superior performance in predicting the incidence of severe RIOM in NPC patients following radiotherapy.

Objective To explore the otherness of orthotopic injection of cell suspensions and transplantation of tumor tissue blocks to establish orthotopic implantation models of hepatocellular carcinoma in mice,and to provide a technical reference for the establishment of an orthotopic implantation model.Methods Healthy KM mice were divided into four groups:group A,direct injection of H22 cells;group B,direct injection of H22 ascitic cells;group C,transplantation of tissues;and group D,direct injection of saline.Activity and weight changes were observed regularly in each group and survival times were recorded.Liver tumor formation,tumor size,abdominal organ adhesion degree,and metastasis were observed in all groups.B-ultrasound imaging was performed,concentrations of alpha fetoprotein(AFP)and abnormal prothrombin(DCP)were detected,and liver histopathological changes were detected by hematoxylin and eosin staining.Results Mice molding operation time in groups A,B,and C were(3.36±0.44)min,(3.30±0.41)min,and(5.68±0.65)min,respectively.After modeling for 25 days,the rates of model formation in groups A,B,and C were all 100.0%.Severe abdominal adhesions occurred in 40.0%of mice in group A and 60.0%in group B,but in no mice in group C or D.Ascites occurred in 40.0%,100.0%,and 0.0%and abdominal wall tumors in 30.0%,60.0%,and 0.0%of mice in groups A,B,and C,respectively,while 40.0%of mice in group B also had liver metastasis.B-ultrasound imaging,detection of serum AFP and DCP levels,and histopathological result showed smooth liver margins,uneven echo and slightly lower echo mass,maintained high AFP and DCP secretion,and large numbers of inflammatory cells and tumor cells in mice in groups A,B,and C.Conclusions At day 25,all three methods can thus be used to establish orthotopic transplantation models of HCC.Among these,inj ection of cell suspensions demonstrated the advantage of simplicity in operation and the presence of multiple metastatic nodules within the liver,compared to transplantation of tumor tissue.Conversely,transplantation of tumor tissue showed the advantage of causing less impact on the abdomen and other organs when compared to inj ection of cell suspensions.

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.

Objective To develop a traditional Chinese medicine (TCM) syndrome score scale for acute gastrointestinal injury (AGI) in sepsis, and to carry out its reliability and validity analyses and its clinical preliminary application. Methods ① According to the characteristics of intensive care unit (ICU) patients, combined with the understanding of etiology, pathogenesis and physical signs of TCM and literature search, a preliminary framework of scoring system for TCM syndromes of AGI in sepsis was constructed to carry out the scoring by this scale. ② After the scale and data were obtained, the analyses of split-half reliability (indicated by Guttman's split-half reliability of the a and b groups), test-retest reliability and the internal consistency reliability (expressed by the Cronbach's coefficient α) were carried out, and the structural validity and criterion validity were also analyzed. ③ The AGI patients were divided into two groups according to the 28-day survival and death conditions, and the AGI TCM syndrome score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, and multiple organ dysfunction syndrome (MODS) score were compared between the two groups to determine the best cut-off point for survival analysis. Results ① The first draft of the septic AGI TCM syndrome rating scale was prepared, The TCM syndrome indicators include: abdominal distension, constipation/diarrhea, diet situation, vomiting/stomach retention, tongue proper, tongue coating, pulse manifestation, belching, body temperature, and accompanied syndrome, there were 6 points for scoring, 0 - 6 points, and they were divided into normal (0 points), mild (2 points), moderate (4 points), and severe (6 points) in severity. ② Eighty-eight patients with septic AGI were included in the final statistics. The retest of correlation coefficient of this scale was R = 0.974 (> 0.85), Guttman's split-half reliability was 0.793 (> 0.7) and the Cronbach's coefficient α was > 0.7. This scale was suitable for factor analysis. After rotation, 3 factors were determined, which were named as TCM syndrome differentiation, related physical signs, and gastrointestinal tolerance. After modeling, the confirmatory factor analysis showed that the model approximate error root mean square (RMSEA) was 0.07 (< 0.08), and the goodness of fit index (CFI) = 0.90; the Pearson correlation analyses between the criteria validity of APACHE Ⅱ, SOFA, MODS scores and TCM 1 score and TCM 2 score of this scale showed that the r values were 0.802 and 0.752, 0.524 and 0.519, 0.619 and 0.590, respectively, all P < 0.01. ③ Compared with the survival group, TCM score (33.73±5.95 vs. 37.28±5.26, t = 2.945, P = 0.004), the APACHE Ⅱ score (19.90±4.47 vs. 22.28±5.79, t = 2.069, P = 0.043), SOFA score (8.73±1.11 vs. 9.64±1.38, t = 3.329, P = 0.020) in the death group were significantly decreased; MODS score in the death group showed a decreasing trend (6.65±1.22 vs. 7.28±1.60, t = 2.078, P = 0.050). Cox regression analysis showed that when the survival analysis was performed with a cut-off point of 35, the 28-day survival rate of patients with TCM syndrome score ≥ 35 was significantly lower than that of patients with < 35 score, χ2= 6.362, P = 0.012. Conclusions The TCM syndrome rating scale for AGI in sepsis was successfully prepared. The statistical reliability and validity of this scale are good. Preliminary clinical application shows that this scale can predict the prognosis and severity of patients with septic AGI.

Objective To investigate the influence of inclusive leadership on organizational performance of nurses and to test the mediating role of empowerment behavior. Methods From November to December 2016, 293 nurses from 2 public hospitals in Harbin were investigated with Inclusive Leadership Scale, Empowerment Behavior Scale and Team Performance Scale. A total of 293 questionnaires were distributed and 251 questionnaires were effectively recovered. Descriptive statistics, Pearson correlation analysis and multiple linear hierarchical regression analysis were performed to analyze and process data. Results The Score of Inclusive Leadership Scale, Empowerment Behavior Scale and Team Performance Scale was (5.28±1.184), (5.25±1.216) and (5.71±1.233) respectively. Inclusive leadership had a positive correlation with empowerment behavior and organizational performance of nurses (r=0.742,0.605;P＜0.05). In addition, there was a positive correlation between empowerment behavior and organizational performance of nursing staff (r=0.615,P＜0.05). Multivariate linear hierarchical regression analysis showed that inclusive leadership had a positive predictive effect on empowerment behavior and organizational performance, and empowerment behavior of nurses partially mediated between them. Conclusions Inclusive leadership can enhance subordinate nurses' high level of empowerment awareness, thereby directly or indirectly improving nursing organization performance.
