Objective To investigate the levels of hypoxia-inducible factor 1α(HIF-1α)and lipopolysaccha-ride signal receptor(CD14)in gingival crevicular fluid of preschool children with dental caries and their clini-cal significance.Methods A total of 468 preschool children(aged 3-6 years)who underwent oral examina-tions in the hospital from April 2022 to May 2024 were selected as the research objects and were divided into the observation group(with dental caries,n=107)and the healthy group(without dental caries,n=361)based on the presence or absence of dental caries.The observation group was further divided into three sub-groups according to the degree of caries activity test(CAT)score:low activity group(n=29),moderate activ-ity group(n=46),and high activity group(n=32).The children in the observation group were followed up for 6 months,and then divided into the occurrence group(n=36)and the non-occurrence group(n=71)based on whether chronic apical periodontitis occurred during the follow-up period.The levels of HIF-1α and CD14 in gingival crevicular fluid in the research objects were detected.The relationship between the levels of HIF-1α and CD14 in gingival crevicular fluid of preschool children with dental caries and CAT score was ex-plored by Pearson correlation analysis.The predictive value of HIF-1α and CD14 levels in gingival crevicular fluid for chronic apical periodontitis in preschool children with dental caries was explored by receiver operating characteristic(ROC)curve.Results The levels of HIF-1α and CD14 in gingival crevicular fluid in the obser-vation group were higher than those in the healthy group(P＜0.05).With the increase of CAT score,the lev-els of HIF-1α and CD14 in gingival crevicular fluid gradually increased(high activity group＞moderate activi-ty group＞low activity group),and the differences were statistically significant(P＜0.05).The levels of HIF-1α and CD14 in gingival crevicular fluid of preschool children with dental caries were positively correlated with CAT score(r=0.526,0.634,P＜0.001).The levels of HIF-1α and CD14 in gingival crevicular fluid in the occurrence group were significantly higher than those in the non-occurrence group(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of combined prediction of HIF-1α and CD14 levels in gingival crevicular fluid for chronic apical periodontitis in preschool children with dental caries was 0.902(95％CI:0.857-0.952),which was higher than 0.709(95％CI:0.664-0.759)and 0.825(95％CI:0.775-0.870)of individual prediction of HIF-1α and CD14 levels in gingival crevicular fluid.Conclusion HIF-1α and CD14 are highly expressed in gingival crevicular fluid of preschool children with dental caries,and their levels are related to the activity of dental caries and the occurrence of chronic apical periodontitis in preschool chil-dren with dental caries.The combined detection of the two can be used as effective indicators for predicting the occurrence of chronic apical periodontitis in preschool children with dental caries.

With advancements in imaging technology, the detection rate of localized renal neoplasms has significantly increased. Minimally invasive partial nephrectomy now represents the mainstream approach for nephron-sparing surgery. However, the potential impairment of residual renal function due to warm ischemia-reperfusion injury and renal wound suturing during traditional surgical procedures constitutes key challenges in current therapeutic management. Maximizing renal parenchymal preservation and reducing ischemia time are core objectives for optimizing efficacy. Zero ischemia techniques aim to avoid or minimize warm ischemia and thereby prevent ischemia-reperfusion injury. This is achieved through strategies including preoperative superselective transarterial embolization, segmental renal artery clamping, early unclamping, or completely off-clamp renal artery management. An completely off-clamp partial nephrectomy is considered the ideal approach for maximal renal function preservation, although it presents challenges in bleeding management. Compared to traditional suturing, sutureless techniques, designed to overcome renal parenchymal damage and reduce ischemia time, leverage tools like electrocoagulators, argon beam coagulator, and various lasers for efficient hemostasis at the renal wound. These techniques significantly reduce damage to renal parenchyma, potentially improving postoperative renal function and lowering the incidence of complications such as urinary leakage. Zero ischemia and sutureless techniques are pivotal developmental directions in renal functional preservation within the field of minimally invasive partial nephrectomy. Therefore, this article reviewed the literature pertaining to these innovative techniques, summarizing the relevant clinical experiences and potential limitations, in order to furnish actionable guidance and essential theoretical support for their broader clinical implementation.

Objective To understand the latent profiles of kinesiophobia in kidney transplant recipients and explore the influencing factors of different profiles.Methods A cross-sectional study was conducted on 230 kidney transplant recipients subjected with convenient sampling from Department of Nephrology,the First Affiliated Hospital of Army Medical University from November 2024 to February 2025.General Information Questionnaire,Tampa Scale of Kinesiophobia-11(TSK-11),Exercise Compliance Questionnaire,Fatigue Scale-14(FS-14),Patient Health Questionnaire-9(PHQ-9)and Chinese Version of the Self-Efficacy to Manage Chronic Disease Scale(C-SEMCD)were used for investigation and latent profile analysis.Univariate analysis and logistic regression analysis were applied to explore the influencing factors of different profiles.Results Kinesiophobia in the participants was classified into 3 latent profiles:fearless movement type-low kinesiophobia group(54 cases,23.48%),cautious movement type-moderate kinesiophobia group(98 cases,42.61%),and resistant movement type-high kinesiophobia group(78 cases,33.91%).Statistical differences were observed among the 3 groups in terms of age,education level,post-operative duration,depression score,fatigue score,and self-efficacy score of chronic disease management(P<0.05).Logistic regression analysis showed that age(OR=8.82,95%CI:1.27～61.10),education level[junior high school or below(OR=0.14,95%CI:0.04～0.50);technical secondary school or senior high school(OR=0.08,95%CI:0.02～0.27)],post-operative duration[<1 year(OR=11.39,95%CI:2.53～51.30);1-5 years(OR=11.05,95%CI:2.48～49.22)],fatigue(OR=1.32,95%CI:1.10～1.59),and depression(OR=1.53,95%CI:1.19～1.98)were influencing factors for resistant movement type-high kinesiophobia in the kidney transplant recipients.Education level(technical secondary school or senior high school:OR=0.32,95%CI:0.12-0.86)and self-efficacy of chronic disease management(OR=0.95,95%CI:0.90-1.00)were influencing factors for cautious movement type-moderate kinesiophobia in the recipients.Conclusion Kinesiophobia in kidney transplant recipients can be classified into 3 latent profiles.Recipients'age,education level,post-operative duration,fatigue,and depression are influencing factors for the resistant movement type-high kinesiophobia,and education level and chronic disease management self-efficacy are important influencing factors for the cautious movement type-moderate kinesiophobia.

Objective:To investigate the recognition of the post competency index system among rural general practice assistant physicians and its influencing factors.Methods:This study was a cross-sectional survey. A questionnaire survey on the recognition of post competency index system was conducted from October 2020 to September 2021 among rural general practice assistant physicians from 10 provinces/municipalities selected by stratified cluster sampling method. The recognition of rural general practice assistant physicians at all levels of indexs and the factors influencing recognition were analyzed.Results:A total of 1 123 questionnaires were distributed and 1 024 valid ones were collected with a recovery rate of 91.18%. Of the 1 024 respondents, 529 were male(51.7%) and 435 were aged 40-49 years(42.5%), which was the highest proportion by age group. The average overall recognition score of the index system was 4.41, and the scores of the primary indexes were 4.32-4.45. Three primary indexes had the highest recognition scores: professional competence, basic health care services, and interpersonal communication and teamwork. The recognition scores on the second level index were 4.18-4.61, and the proportion of recognition scores greater than 4 was over 80%. There were significant differences in the recognition scores of the index system among assistant physicians with different working years, educational background, professional title and work unit ( F/H=6.41, 14.83, 12.45, 7.53, P<0.01). Educational background(associate degree: B=0.091, P=0.015; bachelor degree and above: B=0.196, P<0.001) and professional title(intermediate professional title and above: B=-0.234, P<0.001) were the independent factors influencing the recognition degree of the index system for rural general practice assistant physicians. Conclusions:The post competency index system is generally recognized by rural general practice assistant physician, and academic qualifications and professional title status may influence its recognition.

Objective:To investigate the effect of intravenous application of furosemide on occurrence of cardiac surgery-associated acute kidney injury (CSA-AKI) in patients after cardiac surgery.Methods:The electronic medical records of patients undergoing cardiac surgery in Linyi People′s Hospital from January 2014 to December 2022 were collected and retrospectively analyzed. According to whether CSA-AKI occurred after surgery, the patients were divided into AKI group and non-AKI group and the clinical characteristics between the 2 groups were compared. Multivariate logistic regression was used to analyze the influencing factors of CSA-AKI, and the odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. Results:A total of 2 633 patients were enrolled in the analysis, including 1 601 males (60.8%) and 1 032 females (39.2%). The age was (62.8±8.9) years, ranging from 18 to 85 years. Among the 2 633 patients, 491 (18.6%) developed CSA-AKI. Multivariate logistic regression analysis showed that after adjusting for factors such as the type of operation, intraoperative cardiopulmonary bypass, hypertension, diabetes mellitus, hypoalbuminemia, NYHA cardiac function class Ⅲ/Ⅳ, intraoperative/postoperative aortic balloon counterpulsation, preoperative serum creatinine level, operation duration, and the number of vasoactive drugs used after the operation, postoperative intravenous application of furosemide was still independently associated with the occurrence of CSA-AKI ( OR=2.161, 95 %CI: 1.720-2.715, P<0.001). Conclusions:The incidence of CSA-AKI in patients enrolled in this study was 18.6%. Intravenous use of furosemide after cardiac surgery can increase the risk of CSA-AKI.

Objective:To investigate the current implementation status of early essential newborn care (EENC) core interventions in China.Methods:Based on the Safe Neonatal Project jointly launched by the National Health Commission and United Nations International Children's Emergency Fund (UNICEF), a questionnaire survey was conducted on the implementation of eight EENC core interventions in 161 pilot hospitals. The eight interventions were skin-to-skin contact immediately after birth for at least 90 min, delayed cord clamping (until 1 min after birth or after the cord stopped pulsating), initiation of breastfeeding within the first hour after birth, exclusive breastfeeding at discharge, delayed first bath (24 h after birth), kangaroo mother care, eye care (using erythromycin ointment or other eye drops), and intramuscular injection of vitamin K 1. The survey was completed by the pilot units based on actual conditions from January 1 to December 31, 2022. Neonatal disease information was obtained from medical records from birth to discharge, and neonatal mortality rates were obtained from outpatient and inpatient records in obstetric institutions. The main indicators were the implementation rates of EENC core interventions in the eastern, central, and western regions, as well as the neonatal mortality and the incidence of common neonatal diseases in hospitals that implemented EENC or not. Chi-square test was used for data comparison. Results:A total of 156 pilot hospitals completed the survey, with 66 (42.3%) in the eastern region, 45 (28.8%) in the central region, and 45 (28.8%) in the western region. The implementation rates of skin-to-skin contact immediately after birth for at least 90 min, initiation of breastfeeding within the first hour after birth, exclusive breastfeeding at discharge, kangaroo mother care, eye care, and intramuscular injection of vitamin K 1 were higher in the western region than in the eastern and central regions [60.1% (62 491/104 012) vs. 22.4% (104 991/467 982) and 29.4% (31 419/106 812), 76.5% (78 188/102 266) vs. 41.2% (188 740/458 627) and 62.9% (67 200/106 812), 74.0% (60 062/81 141) vs. 39.7% (181 921/458 627) and 70.2% (74 947/106 812), 27.9% (1 407/5 035) vs. 9.4% (1 670/17 807) and 22.9% (2 510/10 968), 46.9% (48 442/103 313) vs. 23.0% (105 917/461 176) and 31.4% (31 731/100 966), 96.2% (51 674/53 729) vs. 56.6% (263 273/465 433) and 92.1% (98 365/106 812), χ 2 values were 58 218.40, 50 113.04, 55 466.24, 1 456.92, 24 686.13, and 72 696.66, respectively, all P<0.001]. The implementation rates of delayed cord clamping and delayed first bath were higher in the central region than in the eastern and western regions [76.9% (82 161/106 812) vs. 37.0% (163 808/443 285) and 59.3% (60 596/102 266), 75.0% (80 159/106 812) vs. 46.6% (216 935/465 433) and 68.4% (71 161/104 012), χ 2 values were 62 516.10 and 37 987.11, respectively, both P<0.001]. Seventy-six hospitals (48.7%) implemented EENC, while 80 hospitals (51.3%) did not. The neonatal mortality and the incidence of neonatal asphyxia, sepsis, pneumonia, diarrhea, eye infection, and umbilical cord infection were higher in the hospitals that did not implement EENC than in those that did [1.3‰ (478/378 519) vs. 1.0‰ (645/679 795), 1.8% (6 849/378 519) vs. 0.9% (5 895/679 795), 1.0% (3 917/378 519) vs. 0.7% (5 029/679 795), 6.2% (23 481/377 890) vs. 3.8% (25 463/679 795), 0.2% (916/378 519) vs. 0.1% (950/656 781), 0.5% (1 837/370 540) vs. 0.2% (1 403/656 949), 1.1‰ (422/375 149) vs. 0.6‰ (405/672 291), χ 2 values were 22.62, 1 766.11, 184.86, 2 832.09, 100.89, 866.59, and 64.94, respectively, all P<0.001]. Conclusions:About half of the pilot hospitals did not carry out EENC and the implementation of specific measures in hospitals carrying out EENC still needs to be improved. The implementation rate of EENC core measures is high in some regions, but there are regional differences.Neonatal health outcomes were better in hospitals with EENC than in hospitals without EENC.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
