Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Objective:To systematically review and evaluate prediction models for aspiration risk in enteral nutrition patients, providing a reference for the development and application of future models.Methods:Literature related to prediction models for aspiration risk in enteral nutrition patients was searched in China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine disc, Web of Science, Cochrane Library, Embase, and PubMed, with the search period covering from the inception of the databases to August 30, 2024. Two researchers independently conducted literature screening and data extraction, and the PROBAST tool was used to assess the risk of bias and applicability of the included studies.Results:A total of 18 studies were included, involving 24 prediction models, with sample sizes ranging from 103 to 512 and an event rate of 9.46% to 49.87%. The top six predictive variables reported most frequently were baseline age, history of aspiration, length of nasogastric tube insertion, nutritional risk, impaired consciousness, and Acute Physiology and Chronic Health Evaluation-Ⅱscore. The area under the receiver operating characteristic curve of the models ranged from 0.756 to 0.992. Twelve studies reported model calibration, six studies conducted internal validation only, one study conducted external validation only, and four studies performed both internal and external validation. The overall applicability of the 18 studies was good, but the risk of bias was high, mainly due to improper handling of continuous variables and missing data.Conclusions:The aspiration risk prediction models developed in various studies for enteral nutrition patients show good applicability but carry a high risk of bias. Future efforts should focus on further optimizing the model construction process, internal and external validation, and result analysis to provide more reliable and scientific tools for clinical aspiration risk assessment.

Objective To apply a multidimensional neonatal nutritional risk screening scale for hospitalized premature infants to explore its predictive value for extrauterine growth restriction(EUGR)at the time of discharge.Methods A total of 104 premature infants hospitalized in the Neonatal Department of the Second Affiliated Hospital of Kunming Medical University from January 2023 to September 2023 were selected as research subjects.Nutritional risk screening was conducted within 24 hours of admission and weekly thereafter using the multidimensional neonatal nutritional risk screening scale.Scoring was based on four dimensions(birth status,weight changes,nutritional intake methods,and disease diagnosis),with a total score of ≥ 8 indicating high risk;≥4 and＜8 indicating moderate risk;and＜4 indicating low risk.EUGR at the time of discharge was the primary clinical outcome indicator.Receiver operating characteristic(ROC)curves were constructed to explore the predictive value of neonatal nutritional risk screening for EUGR in premature infants.Results At discharge,40 premature infants(38.5％)experienced EUGR.The nutritional risk screening scores of the EUGR group on day 7 of hospitalization were higher than those of the non-EUGR group(P＜0.05).The rate of high nutritional risk on day 7 of hospitalization was highest(7.9％in the non-EUGR group,22％in the EUGR group,and 13.5％overall).On both day 1 and day 7 of hospitalization,the rate of high nutritional risk in the EUGR group was higher than that in the non-EUGR group(P＜0.05).There were significant differences in the nutritional risk screening scores on day 7,birth weight Z-scores,discharge corrected gestational age weight Z-scores,and serum albumin levels between the EUGR and non-EUGR groups(P＜0.05).ROC curves were plotted,yielding AUCs of 0.625(95％CI 0.514,0.736),0.652(95％CI 0.544,0.760),0.674(95％CI 0.561,0.786),and 0.641(95％CI 0.531,0.750),indicating certain predictive value.A combined predictive ROC model yielded an AUC of 0.786(95％CI 0.692,0.880)for EUGR,which was higher than the AUCs for individual indicators(P＜0.001).Conclusion The occurrence of EUGR is relatively common among hospitalized premature infants.The nutritional risk is highest during the first week of hospitalization.The multidimensional neonatal nutritional risk screening scale can dynamically assess nutritional risk during hospitalization and may serve as one of the early warning indicators for EUGR in premature infants.The predictive efficacy for EUGR is enhanced when combined with birth weight Z-scores,discharge weight Z-scores,and serum albumin,providing a basis for individualized nutritional management of premature infants.

Objective To investigate the regulatory mechanism of long non-coding RNA(lncRNA)ENST00000579933(hereinafter referred to as lncRNA ENST 933)on the development of breast cancer(BC).Methods The expression level of lncRNA ENST 933 in BC tissues as well as in BC cell lines(MCF-7,MDA-MB-231,MDA-MB-453)was detected by fluorescence-based real-time quantitative polymerase chain reaction RT-qPCR.The effects of lncRNA ENST 933 and miR-588 on the proliferation,migration,invasion and cell cycle in BC were determined using CCK-8 assay,clone formation assay,EdU,Transwell assay,flow cytometry,Western blotting and in vivo transplantation tumor assay.Finally,dual luciferase reporter gene,RNA immunoprecipitation assay,RT-qPCR,Western blotting and rescue assay were used to evaluate the interactions among lncRNA ENST 933,miR-588,and eukaryotic initiation factor 6(EIF6).Results The expression of lncRNA ENST 933 was up-regulated in both BC tissues and BC cell lines(P＜0.05).Overexpression of lncRNA ENST 933 could enhance the proliferation,migration and invasion abilities of BC cells and promote the growth of transplanted tumors,while knockdown of lncRNA ENST 933 resulted in inhibited development of BC and arrested cell cycle(P＜0.05).The expression of miR-588 was obviously down-regulated in BC tissues,and its overexpression inhibited cell proliferation,migration and invasion abilities in the BC cells(P＜0.05).Moreover,the results of rescue assay indicated that lncRNA ENST 933 promoted the expression of target gene EIF6 by competitively binding with miR-588.Western blotting revealed that miR-588 decreased the phosphorylation of AKT and mTOR(P＜0.05).Conclusion lncRNA ENST 933 promotes the progression of BC by modulating the miR-588/EIF6 axis.

【Objective】 To investigate the prevalence and influencing factors of overweight and obesity among preschool children in Suzhou. 【Methods】 A stratified cluster random sampling method was used to select 24 452 children aged 3 - 6 years in different districts of Suzhou from December 2021 to June 2022. Then the prevalence rate of overweight and obesity was determined by physical measurements. A case-control study was conducted with a questionnaire survey of 3 786 children(1 893 in the obesity group and 1 893 in the control group) to analyze the factors influencing preschool obesity. 【Results】 1) The overall detection rates of overweight among preschool children in Suzhou was 14.8%(boys 14.6%, girls 15.0%). The overall detection rates of obesity was 7.9%(boys 8.7%, girls 7.1%), with a statistically significant difference between boys and girls(χ²=19.828, P<0.01). 2) There was statistically significant difference in the detection rates of obesity among different age groups(χ²=98.415, P<0.01), with the lowest rate in the 3 - 4 years old group(5.8%) and the highest rate in the 6 - 7 years old group(11.8%). 3) The overall detection rates of mild, moderate and severe obesity was 4.8%, 2.6% and 0.5%, respectively. The proportion of moderate and severe obesity significantly increased with age(χ²=57.275, P<0.01). 4) Risk factors for preschool obesity included birth weight >4 000g, cesarean section, parental overweight/obesity, strong appetite of children, eating speed <10min/meal, high frequency of fried food consumption(>1time/week), eating while watching television, sedentary behavior >2h/d, insufficient exercise endurance, screen time >1h/d, and late bedtime(after 21∶30)(P<0.05). Protective factors for preschool obesity included larger breakfast consumption, fruits and vegetables as regular snacks, and physical activity after meals(P<0.05). 5) Factors influencing the degree of preschool obesity included paternal overweight(OR=1.33, 95%CI:1.06 - 1.65), paternal obesity(OR=1.91, 95%CI:1.46 - 2.49), maternal overweight(OR=1.25, 95%CI:1.01 - 1.54), maternal obesity(OR=1.94, 95%CI:1.40 - 2.69), low education level of father(junior high school or below)(OR=1.57, 95%CI:1.25 - 1.96), strong appetite of children(OR=1.72, 95%CI:1.41 - 2.11), eating speed <10min/meal(OR=1.29, 95%CI:1.05 - 1.57), sedentary behavior >2h/d(OR=1.51, 95%CI:1.24 - 1.85), insufficient exercise endurance(OR=1.56, 95%CI:1.12 - 2.19), and screen time>1h/d(OR=1.42, 95%CI:1.16 - 1.75). 【Conclusions】 The detection rates of overweight and obesity among preschool children in Suzhou are relatively high, and the detection rate and severity of obesity increase with age. In addition to genetic factors, preschool obesity are also associated with pregnancy and birth history, as well as unhealthy lifestyle after birth.

Objective:To explore the application of virtual reality technology (VR) in clinical internship teaching of thoracic surgery nursing.Methods:A total of 60 nursing students from colleges and universities interning at Shanghai Pulmonary Hospital affiliated to Tongji University during April to December 2023 were randomly divided into observation group ( n=40) and control group ( n=20) in a 2∶1 ratio. In addition to observing a 20-min multimedia video of non-invasive positive pressure ventilation nursing, the control group received traditional teaching and 30-min exercises, while the observation group received 30-min VR-based interactive teaching and 30-min targeted exercises. Standardized patients were applied for student assessment, and the scores of the two groups on days 1, 8, 15, and 29 were compared. At the same time, the students' self-efficacy and self-satisfaction were evaluated, and the number of skill training repetitions and time investment of the teachers from day 15 to 28 were recorded. SPSS 20.0 was used to perform the chi-square test and t-test. Results:The standardized patient assessment scores on days 1, 8, 15, and 29 were (69.14±7.02), (75.22±7.42), (79.14±7.99), and (90.14±8.94) in the observation group, respectively, and were (65.25±6.77), (70.14±6.95), (74.36±7.14), and (82.69±8.85) in the control group, respectively, which were all significantly different between the two groups ( P<0.05). The observation group also showed a significantly higher total General Self-Efficacy score [(24.60±3.68) vs. (20.47±3.25), P<0.05] and a significantly higher self-satisfaction score [(6.12±0.70) vs. (5.57±0.65), P<0.05] than the control group. For the teachers, the observation group had a significantly fewer number of training repetitions [(8.14±0.98) vs. (10.25±1.16), P<0.05] and significantly less time invested [(10.28±1.17) vs. (12.14±1.35) h, P<0.05] compared with the control group. Conclusions:VR technology can improve the teaching performance, self-efficacy level, and self-satisfaction level for clinical nursing internships, and reduce skill training repetitions and time investment for teachers.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
