Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Schistosomiasis was once hyper-endemic in Yunnan Province. Following concerted efforts for over 70 years, remarkable achievements have been made for schistosomiasis control in the province. In 2004, the Mid- and Long-term Plan for Schistosomiasis Prevention and Control in Yunnan Province was initiated in Yunnan Province, and the target for transmission control of schistosomiasis was achieved in the province in 2009. Following the subsequent implementation of the Outline for Key Projects in Integrated Schistosomiasis Control Program (2009—2015) and the 13th Five - year Plan for Schistosomiasis Control in Yunnan Province, no acute schistosomiasis had been identified in Yunnan Province for successive 12 years, and no local Schistosoma japonicum infections had been detected in humans, animals or Oncomelania hupensis snails for successive 6 years in the province by the end of 2020. The transmission of schistosomiasis was interrupted in Yunnan Province in 2020. This review summarizes the history of schistosomiasis, changes in schistosomiasis prevalence and progress of schistosomiasis control in Yunnan Province, and proposes the future priorities for schistosomiasis control in the province.

Objective To predict the potential geographic distribution of Oncomelania hupensis in Yunnan Province using random forest (RF) and maximum entropy (MaxEnt) models, so as to provide insights into O. hupensis surveillance and control in Yunnan Province. Methods The O. hupensis snail survey data in Yunnan Province from 2015 to 2016 were collected and converted into O. hupensis snail distribution site data. Data of 22 environmental variables in Yunnan Province were collected, including twelve climate variables (annual potential evapotranspiration, annual mean ground surface temperature, annual precipitation, annual mean air pressure, annual mean relative humidity, annual sunshine duration, annual mean air temperature, annual mean wind speed, ≥ 0 ℃ annual accumulated temperature, ≥ 10 ℃ annual accumulated temperature, aridity and index of moisture), eight geographical variables (normalized difference vegetation index, landform type, land use type, altitude, soil type, soil textureclay content, soil texture-sand content and soil texture-silt content) and two population and economic variables (gross domestic product and population). Variables were screened with Pearson correlation test and variance inflation factor (VIF) test. The RF and MaxEnt models and the ensemble model were created using the biomod2 package of the software R 4.2.1, and the potential distribution of O. hupensis snails after 2016 was predicted in Yunnan Province. The predictive effects of models were evaluated through cross-validation and independent tests, and the area under the receiver operating characteristic curve (AUC), true skill statistics (TSS) and Kappa statistics were used for model evaluation. In addition, the importance of environmental variables was analyzed, the contribution of environmental variables output by the models with AUC values of > 0.950 and TSS values of > 0.850 were selected for normalization processing, and the importance percentage of environmental variables was obtained to analyze the importance of environmental variables. Results Data of 148 O. hupensis snail distribution sites and 15 environmental variables were included in training sets of RF and MaxEnt models, and both RF and MaxEnt models had high predictive performance, with both mean AUC values of > 0.900 and all mean TSS values and Kappa values of > 0.800, and significant differences in the AUC (t = 19.862, P < 0.05), TSS (t = 10.140, P < 0.05) and Kappa values (t = 10.237, P < 0.05) between two models. The AUC, TSS and Kappa values of the ensemble model were 0.996, 0.954 and 0.920, respectively. Independent data verification showed that the AUC, TSS and Kappa values of the RF model and the ensemble model were all 1, which still showed high performance in unknown data modeling, and the MaxEnt model showed poor performance, with TSS and Kappa values of 0 for 24%(24/100) of the modeling results. The modeling results of 79 RF models, 38 MaxEnt models and their ensemble models with AUC values of > 0.950 and TSS values of > 0.850 were included in the evaluation of importance of environmental variables. The importance of annual sunshine duration (SSD) was 32.989%, 37.847% and 46.315% in the RF model, the MaxEnt model and their ensemble model, while the importance of annual mean relative humidity (RHU) was 30.947%, 15.921% and 28.121%, respectively. Important environment variables were concentrated in modeling results of the RF model, dispersed in modeling results of the MaxEnt model, and most concentrated in modeling results of the ensemble model. The potential distribution of O. hupensis snails after 2016 was predicted to be relatively concentrated in Yunnan Province by the RF model and relatively large by the MaxEnt model, and the distribution of O. hupensis snails predicted by the ensemble model was mostly the joint distribution of O. hupensis snails predicted by RF and MaxEnt models. Conclusions Both RF and MaxEnt models are effective to predict the potential distribution of O. hupensis snails in Yunnan Province, which facilitates targeted O. hupensis snail control.

Objective To investigate the reasons for the inconsistent results between the vertical auto profile(VAP)method and bio-chemical homogeneous phase(BHP)method in detecting plasma low-density lipoprotein cholesterol(LDL-C),and provide experimen-tal basis for the accurate and quantitative detection of plasma LDL-C levels.Methods A total of 360 plasma samples from diabetes mellitus patients combined with carotid plaque admitted to the Department of Endocrinology of Ningbo Yinzhou Hospital of Traditional Chinese Medicine during January,2022 and January,2023 were collected.The LDL-C levels of these samples were detected by the VAP method and BHP method,respectively.The VAP method uses software to automatically calculate the area under the LDL-C curve after centrifugation of the sample as the LDL-C level(LDL-CVAP)and the BHP method directly detects the LDL-C level(LDL-CBHP)by the special surfactant method.360 samples were divided into the consistent group(group A)and inconsistent group(group B)ac-cording to the relative deviation between the LDL-CBHP and LDL-CVAP methods.Group B was further divided into the LDL-CBHP on the high side group(Group B1)and LDL-CBHP on the low side group(Group B2).Groups B1 and B2 were divided into B1-1,B1-2,B1-3 and B2-1 groups based on the degree of relative deviation.The percentages of samples and levels of lipoprotein a cholesterol[Lp(a)-C],intermediate-density lipoprotein cholesterol(IDL-C),Lp(a)-C and IDL-C[Lp(a)-C+IDL-C],very low-density lipo-protein cholesterol(VLDL-C),total cholesterol(TC)and total triglyceride(TG)in each group were compared.Results The LDL-CBHP levels of 360 samples were significantly higher than that of LDL-CVAP(P<0.01).The percentage of samples in group B was significantly higher than that in group A,and that of group B1 was significantly higher than that of group B2(P<0.05).The levels of Lp(a)-C,IDL-C and Lp(a)-C+IDL-C in groups B1-1,B1-2,and B1-3 were significantly higher than those in group A(P<0.01).The relative deviation between LDL-CBHP and LDL-CVAP in 360 samples was significantly positively correlated with the levels of Lp(a)-C,IDL-C,and Lp(a)-C+IDL-C(P<0.01).The maximum correlation coefficient was found in Lp(a)-C+IDL-C.Conclusion The results of plasma LDL-C in diabetes mellitus patients combined with carotid plaque detected by the BHP method are significantly different from those detected by the VAP method,which mainly shows that the results of the BHP method are on the high side.The higher the level of plasma Lp(a)-C+IDL-C,the greater the relative deviation between the BHP method and VAP method.The reason for the high results of LDL-C detected by the BHP method may be related to the fact that LDL-CBHP contains irremovable Lp(a)-C and cholesterol carried by IDL-C.The VAP method can be used as an accurate method for detecting real LDL-C without Lp(a)-C and IDL-C.

Objective:To explore the status quo of pediatric nurses' cognition of death education, and analyze its influencing factors, so as to provide experience and reference for carrying out death education in pediatric wards.Methods:In this study, 827 nurses from 15 children's hospitals in China were investigated by using the scale for evaluating the cognition of death education in medical staff prepared by Zhang Yan-gai, and the related factors affecting the cognition of death education were analyzed. SPSS 23.0 was used for independent-samples t-test and ANOVA analysis, and multiple regression equation was used to further analyze the relationship between the cognitive factors of death education in pediatric nurses. Results:The total score of death education cognition of pediatric nurses was (35.61±5.64) points, which was lower than the median score of 36 points. The degree of death education cognition of pediatric nurses was at the medium-low level. The results of correlation analysis showed that the professional title of nurses (regression coefficient: 0.064, P=0.045), the training demand for death education (regression coefficient: 0.300, P<0.001), and the way of understanding (regression coefficient: 0.018, P=0.003) were independent influencing factors of the death education cognition level of pediatric nurses. Conclusions:Pediatric nurse death education related theoretical knowledge should be improved through various professional trainings. The hospitals should include death education in pediatric nurse continuing education training plan to improve pediatric nurses' cognitive level of death education through a variety of ways and means, promote the application of death education activities carried out in pediatric ward in the hospice care, reduce deaths impact to nurse their own emotions, and alleviate parents' anxiety and painful experience, thereby improving medical satisfaction.
