Upward influence tactics (UIT) have been a significant research topic for both Western and East Asian researchers. As cultural differences lead to different UIT, scholars often adopt different cultural approaches to investigate the differences in UIT across different cultural areas. Specifically, some scholars assumed that Western UIT is culturally universal and directly applied Western UIT models into East Asia, while others adopt an indigenous approach to explore the Eastern UIT from an emic perspective. Despite the considerable amount of studies, different research approaches have led to disagreements and overlaps in the content of UIT, signaling a need for an integrative framework on UIT contents from different cultures. As such, this study aims to provide an integrative framework that can integrate and classify UIT from Western and East Asia. Specifically, we first conducted a review of previous literature on UIT and selected 28 representative UITs. We illustrated an integrative, two-dimensional framework based on these 28 UITs and examine its validity. Subsequently, we recruited 285 participants and requested them to rate each UIT in terms of similarity with others. We adopted Multi-dimensional scaling (MDS) to analyze the data. The results support the twodimensional framework, and finally we discuss future directions and provide research suggestions to contribute to future exploration of UIT. [ABSTRACT FROM AUTHOR]

Objective: To study the predictive value of three-dimensional energy Doppler ultrasound combined with serum human epididymal protein 4 (HE4), thymidine kinase 1 (TK1) and chitinase protein 40 (YKL-40) for endometrial cancer in postmenopausal bleeding patients. Methods: 150 postmenopausal bleeding patients who were admitted from October 2019 to October 2022 in the our hospital were selected. They were divided into endometrial carcinoma group (31 cases) and endometrial benign hyperplasia group (119 cases) according to the difference of pathological examination results. Three-dimensional energy Doppler ultrasound was performed in all patients, and serum HE4, TK1, YKL-40 levels were detected. The efficacy of three-dimensional energy Doppler ultrasound combined with serum HE4, TK1, and YKL-40 levels in predicting endometrial cancer in postmenopausal bleeding patients was analyzed by receiver operating characteristic curve (ROC). Results: Blood flow index (FI), angiogenesis index (VI), angiogenesis - blood flow index (VFI) and the composite index I constructed by these three parametersin endometrial cancer group were higher than those in endometrial benign hyperplasia group (all P<0.05). The serum levels of HE4, TK1 and YKL-40 in endometrial cancer group were higher than those in endometrial benign hyperplasia group (all P<0.05). Through ROC curve analysis found that the area under the curve(AUC), sensitivity, specificity and Yoden index of three-dimensional energy Doppler ultrasound combined with serum HE4, TK1 and YKL-40 levels in predicting endometrial cancer in postmenopausal bleeding patients were higher than those of the four independent predictions. Conclusion: Three-dimensional energy Doppler ultrasound combined with serum HE4, TK1 and YKL-40 levels were more effective in predicting endometrial cancer in postmenopausal bleeding patients.

BACKGROUND: Traditional 3D dental segmentation methods usually utilize predefined spatial geometric features, such as curvature and normal vectors, as the reference information for tooth segmentation. OBJECTIVE: To propose an algorithm for complex 3D dental segmentation and deeply explore the correlation between segmentation results and application scenarios. METHODS: A 3D dental segmentation algorithm based on dual stream extraction of structural features and spatial features was established, and the modular design of split flow was used to avoid feature confusion. Among them, the attention mechanism on the structural feature flow was used to capture the finegrained semantic information required for tooth segmentation, and the Tran Net based on the spatial feature flow was used to ensure the robustness of the model to complex tooth and jaw segmentation. This algorithm verified its effectiveness and reliability based on clinical datasets including healthy dental jaws and complex dental jaws such as missing teeth, malocclusion and dentition crowding. The segmentation performance of the model was measured in terms of overall accuracy, mean intersection over union, and directional cut discrepancy. RESULTS AND CONCLUSION: The overall segmentation accuracy of this algorithm in the clinical data set is 97.08%, and the segmentation effect is superior to that of other competitive methods from the qualitative and quantitative perspectives. It is verified that the structural feature flow designed in this paper can extract more precise local details of tooth shape from coordinate and normal information by constructing an attention aggregation mechanism, and the spatial feature flow designed in this paper can ensure the robustness of the model to complex teeth such as missing teeth, dislocated teeth, and crowded dentition by constructing a transformation network (Tran Net). Therefore, this tooth segmentation algorithm is highly reliable for clinicians' practical reference. [ABSTRACT FROM AUTHOR]

Objective To compare the clinical effects of combined spinal epidural anesthesia (CSEA) at different times on the analgesic effect and satisfaction of primipara. Methods 504 primipara were included in this study. According to different degrees of cervical dilatation, the primipara with CSEA were divided into： Group Ⅰ (from labor to cervical dilation < 2 cm, n = 112 cases), group Ⅱ (2 cm ≤ Cervical dilation < 5 cm, n = 176 cases), group Ⅲ (cervix dilation ≥ 5 cm, n = 111 cases), control group (no neuraxial anesthesia for labor analgesia, n = 105 cases), in order to compare the effect of labor analgesia and satisfaction at different groups. Results The visual analogue scale (VAS) scores for group Ⅰ and group Ⅱ exceeded 3 points after 4 hours of labor analgesia, while the VAS scores for group Ⅲ exceeded 3 points after 3 hours of labor analgesia. The incubation period and the duration of the second stage of labor in group Ⅰ and group Ⅱ were longer than those in group Ⅲ and control group (all P < 0.05). The incidence of uterine atony in group Ⅰ, group Ⅱ and group Ⅲ were higher than those in the control group (all P < 0.05). The incidence of fever and urinary retention in group Ⅰ, group Ⅱ and group Ⅲ were higher than that in control group (all P < 0.05). The satisfaction levels of primiparous women in group Ⅰ and group Ⅱ were significantly higher than those in group Ⅲ and control group (all P > 0.05). Conclusion CSEA can effectively relieve pain for primiparous women after labor until the cervix is fully dilated. However, 4 hours after CSEA within 5 cm of the cervix, 3 hours after CSEA for cervix dilation larger than 5 cm, the anesthetic dose should be adjusted in time according to the pain score to achieve effective analgesia. It is important to observe and treat side effects related to anesthesia drugs in a timely manner to improve the satisfaction of primiparous women. [ABSTRACT FROM AUTHOR]

Objective To investigate the prognosis of serum bicorticotin-like kinase 1 （DCLK1） and soluble T cell immunoglobulin mucin molecule 3 （sTim-3） in patients undergoing radical prostatectomy. Methods This study selected 80 patients who underwent radical prostatectomy in our hospital from June 2016 to June 2019 as the research group, and another 80 healthy individuals who underwent physical examination during the same period as the control group; enzyme linked immunosorbent assay （ELISA） was applied to detect serum levels of DCLK1 and sTim-3; The relationship between serum DCLK1 and sTim-3 and pathologic features and prognosis of patients undergoing radical prostatectomy was analyzed. Results The serum levels of DCLK1 and sTim-3 in the study group were obviously higher than those in the control group （P < 0.05）. Serum DCLK1 and sTim-3 levels were positively correlated （P < 0.05）. Both were positively correlated with PSA level and Gleason score （P < 0.05）. Serum DCLK1 and sTim-3 expression levels were associated with PSA levels, Gleason scores, and TNM stages （P < 0.05）. The serum levels of DCLK1 and sTim-3 in the prognostic death group were significantly higher than those in the prognostic survival group （P < 0.05）. Patients with high expression of DCLK1 and sTim-3 had lower survival rates than those with low expression. According to Cox regression analysis, high expression of DCLK1 and sTim-3 was a risk factor affecting the prognosis of patients undergoing radical prostatectomy （P < 0.05）. According to the ROC curve, the AUC that jointly predicted the prognosis of patients undergoing radical prostatectomy was better than that of DCLK1 and sTim-3 respectively. Conclusion DCLK1 and sTim-3 are obviously elevated in the serum of prostate cancer patients, and their combination can better evaluate the prognosis of patients undergoing radical prostatectomy.
