Cleft lip and palate, as one of the most common congenital deformities of the oral and maxillofacial region, not only affects the physiological functions of patients, but also has a profound impact on their psychological well-being. Traditional sequential treatment for cleft lip and palate aims to restore primary functions and typically concludes intervention after orthodontic treatment. However, this management protocol often fails to meet patients′ expectations for esthetic outcomes. In the process of dental esthetic restoration, it is essential to adhere to the principles of comprehensive planning, sequential treatment, and tooth preservation, while formulating individualized treatment strategies. This article delves into the main challenges and corresponding therapeutic measures in dental esthetic restoration following sequential treatment for cleft lip and palate patients. It systematically analyzes the causes, clinical manifestations, and treatment methods for esthetic defects in dental arch space, dental hard tissues, and periodontal soft tissues. The study proposes that dental esthetic restoration can be implemented during three critical phases of sequential treatment: the mixed dentition stage, early permanent dentition stage, and adulthood stage to reduce the complexity of subsequent treatments, thereby preserving more dental and periodontal tissues. Through multidisciplinary collaboration and the application of digital technology, not only has the efficiency and predictability of treatment been enhanced, but more economical and effective treatment options have also been provided for patients. The aim is to offer clinicians comprehensive treatment insights, promoting a shift in the treatment philosophy for cleft lip and palate patients from "function-oriented" to a multidimensional approach that equally emphasizes" function-aesthetics-psychosocial aspects", ultimately achieving a comprehensive improvement in patients′ quality of life.

Objective:To assess the association between temperature and risk of animal injury, and identifying vulnerable populations.Methods:Based on a time-stratified case-crossover design, the number of animal injuries monitored in hospitals of Guangdong Provincial Injury Surveillance System in 2011 and 2015-2016 was included, and the daily meteorological data were derived from the fifth generation of European ReAnalysis-Land, which was produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression combined with a distributed lagged nonlinear model was applied to analyze the association of temperature and animal-specific injuries. We also conducted stratified analysis by region, sex, age, occupation, and location of injury occurrence.Results:There was an almost linear relationship between temperature and the occurrence of animal injury. The excess risk ( ER) of animal injury was 2.65% (95% CI: 2.27%-3.04%) for a 1 ℃ rise in temperature with much higher risk of occurrence ( ER=9.34%, 95% CI: 7.57%-11.13%) for non-mammalian injury than that for mammalian injuries ( ER=2.30%, 95% CI: 1.90%-2.70%). Stratified analysis revealed that the occurrence of animal injury was more susceptible to temperature influences in urban ( ER=2.78%, 95% CI: 2.35%-3.21%), female ( ER=2.71%, 95% CI: 2.16%-3.27%), the elderly aged 60 years and above ( ER=3.05%, 95% CI: 1.65%- 4.47%), farmer ( ER=4.66%, 95% CI: 3.03%-6.32%) and agricultural area ( ER=10.63%, 95% CI: 7.57%-13.79%) than their correspondents. In terms of mammalian injury, dog bites showed the highest risk ( ER=2.71%, 95% CI: 2.12%-3.30%). In terms of non-mammalian,snake injuries were highly influenced by temperature ( ER=16.74%, 95% CI: 11.33%-22.40%). Conclusions:The ambient temperature rises could increase the risk of animal injury with much higher risk for non-mammalian than that for mammalian injuries. Our findings suggest that global warming may increase the risk and disease burden from animal injuries.

Objective To explore the mediating effect of empowerment ability between type D personality and self-management behavior of patients with diabetes mellitus(DM).Methods A total of 738 patients with type 2 diabetes mellitus(T2DM)hospitalized in the Department of Endocrinology of three tertiary hospitals in Hainan Province from December 2022 to May 2023 were selected and divided into Type D personality(Type D,n=104)group and T2DM group(n=634).The general data,biochemical indexes,scores of negative emotion(NA),social inhibition(SI),empowerment ability,and scale of DM self-management activities(SDSCA)were compared between the two groups,and the correlation between type D personality,empowerment ability and self-management ability was analyzed.The mediating effect model was used to analyze the mediating effect of empowerment ability on the four self-management behaviors of patients with type D personality,and the chain mediating effect model was used to analyze the relationship between type D personality,empowerment ability,self-management behaviors and HbA1c.Results Compared with the T2DM group,HbA1c,proportion of rural residence,proportion of complications≥3,proportion of education level of junior high school or above,proportion of monthly income<3000 yuan,and NA and SI scores were significantly higher in the Type D group(P<0.05).The empowerment ability and scores of healthy diet,regular exercise,blood glucose monitoring and medication compliance were lower in the Type D group than in the T2DM group(P<0.05).Spearman correlation analysis showed that the empowerment ability score was positively correlated with the scores of healthy diet,regular exercise,blood glucose monitoring and medication compliance(P<0.05).NA and SI scores were negatively correlated with empowerment ability score,healthy diet,regular exercise,blood glucose monitoring and medication compliance(P<0.05).The results of model analysis with empowerment ability as the mediating variable showed that type D personality had direct,indirect and total effects on regular exercise,blood glucose monitoring,medication compliance and SDSCA total score(P<0.05),and indirect and total effects on regular diet score(P<0.05).The mediating effect of empowerment ability was significant(Bootstrap CI did not include 0).The chain mediating effect analysis showed that type D personality could indirectly affect HbA1c through empowerment ability,healthy diet(γ=0.389,95%CI 0.206～0.591),and medication compliance(γ=0.149,95%CI 0.040～0.265),and the effect proportion was 39.4%and 14.1%,respectively.Conclusions Type D personality can indirectly influence self-management behavior through the mediating effect of empowerment,and simultaneously affecting HbA1c through the chain effect of empowerment,diet,and medication behavior.

Objective:To compare the pregnancy outcomes of surviving fetuses in monochorionic diam-niotic(MCDA)twin pregnancies after selective feticide or spontaneous single intrauterine fetal demise(sIUFD),and to explore the influencing factors of prognosis.Methods:A total of 219 cases of intra-uterine death of one fetus in MCDA twin pregnancies admitted to Peking University Third Hospital from September 2010 to August 2021 were collected.According to the mode of fetal death,they were divided into the spontaneous sIUFD group(120 cases)and the selective feticide group(99 cases).Data on the maternal conditions during pregnancy,the situation of the intrauterine-dead fetus,and pregnancy out-comes were collected for retrospective case-analysis.Results:The live-birth rates of surviving fetuses in the spontaneous sIUFD group and the selective feticide group were 85.0％and 81.8％respectively,and the total perinatal survival rates of surviving fetuses were 73.3％and 81.8％respectively,and there were no statistically significant differences.Compared with the spontaneous sIUFD group,the selective feticide group had a greater gestational week at delivery,and lower rate of preterm birth before 37 weeks,neonatal asphyxia,and early neonatal mortality.Using the gestational week at delivery as the outcome variable,Cox regression analysis showed that the mode of fetal death was not a risk factor affecting the gestational week at delivery of the surviving fetus,while gestational hypertension and the gestational week of fetal death were independent risk factors affecting the gestational week at delivery of the surviving fetus.Using preterm birth before 37 weeks,intrauterine death of the surviving fetus,and abnormal neonatal cranial ultrasound as outcome variables respectively,unconditional logistic regression analysis showed that the mode of fetal death,the gestational week of fetal death,the position of the dead fetus,and fetal complications were independent risk factors affecting the outcomes of the above-mentioned survi-ving fetuses.According to the results of the univariate analysis,the above risk factors were included in the multivariate regression analysis,and the results were the same as those of the univariate analysis.Conclusion:For MCDA twin pregnancy patients with severe twin-related complications,the prognosis of surviving fetuses after selective feticide is better.The proactive intrauterine intervention and treatment are of great significance for improving the prognosis of surviving fetuses.

OBJECTIVE To observe the effect of Jiangqi Pingxiao Formula on airway inflammation in mice with acute asthma and explore its possible mechanism.METHODS A total of 36 BALB/c mice were randomly divided into normal group,model group,dexamethasone group,low-dose,medium-dose and high-dose groups of Jiangqi Pingxiao Formula,with 6 mice in each group.Except for the normal group,the other groups were given ovalbumin to establish the acute asthma attack mouse model.The normal group and the model group were given distilled water by gavage,and the Jiangqi Pingxiao Formula groups were given Jiangqi Pingxiao Formula by gavage at the corresponding dose,once a day,for 5 consecutive days.Whole Body Plethysmography was used to measure the changes of enhanced respiratory interval(Pehn)of bronchial contraction parameters in mice.HE staining was used to observe the pathological changes of lung tissue in mice.ELISA method was adopted to detect the expression levels of interleukin 1β(IL-1β),interleukin 18(IL-18)and tumor necrosis factor α(TNF-α)in lung tissue homogenate of mice.Immunohistochemistry method was used to detect the expression level of NOD-like receptor pyrin domain-associated protein 3(NLRP3)in lung tissue of mice.Western blot method was employed to detect the expression of NLRP3 inflammasome activation-associated protein κ gene binding nuclear factor-κB(NF-κB),NOD-like receptor pyrin domain-associated protein 3(NLRP3),NIMA-associated kinase 7(NEK7),Caspase 1(Cleaved-Caspase 1)and apoptosis-associated speck-like protein(ASC)in lung tissue of mice.RESULTS Compared with the normal group,the Penh level of mice in the model group was increased(P<0.001),and the pathological results of lung tissue showed that the number of inflammatory cells around the airway increased,the inflammatory score increased(P<0.001),the expression of IL-1β,IL-18,and TNF-α in lung tissue homogenate increased(P<0.001),and the expression of NF-κB,NLRP3,NEK7,Cleaved-Caspase 1,and ASC proteins in lung tissue increased(P<0.05,P<0.01,P<0.001).Compared with the model group,the Penh level of mice in the Jiangqi Pingxiao Formula groups and the dexamethasone group was reduced(P<0.05,P<0.001),the number of inflammatory cells in lung tissue decreased,and the inflammatory score decreased(P<0.001);the expression of IL-1β,IL-18,and TNF-α in lung tissue homogenate decreased(P<0.05,P<0.01,P<0.001);the expression of NF-κB,NLRP3,NEK7,Cleaved-Caspase 1,and ASC pro-teins in lung tissue decreased(P<0.05,P<0.01,P<0.001).CONCLUSION Jiangqi Pingxiao Formula can improve lung function and airway inflammation in asthma model mice,and its mechanism may be related to regulating NLRP3 inflammasome-mediated IL-1β secretion.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.

Objective:To analyze the time to reach full enteral feedings (TFEF) among preterm infants with gestational age (GA)<32 weeks admitted to the neonatal intensive care unit (NICU) of Chinese Neonatal Network (CHNN).Methods:This was a retrospective analysis based on the database from the CHNN 89 participating centers between January 1 st, 2019 and December 31 st, 2022. All 16 155 preterm infants with a GA <32 weeks and a birth weight <1 500 g, admitted to the NICU within 24 h after birth, hospitalization for at least 7 d and achieved full enteral feedings before discharge were included. According to the birth weight, these infants were divided into extremely low birth weight (ELBW) group and very low birth weight (VLBW) group. The practice characteristics of TFEF across different GA, the severity of neonatal admission, the NICU interventions before reaching full enteral feeding, and relevant neonatal diseases were described. Mann-Whitney U tests or Kruskal-Wallis H tests was used for comparison between groups. Results:Among the 16 155 preterm infants with a GA <32 weeks, 8 505 case (52.6%) were male. The TFEF in 3 374 cases of ELBW groups was 32 (22, 46) d, 351 cases (10.4%) with TFEF ≤2 weeks, 1 050 cases (31.1%) with TFEF >2-4 weeks, 964 cases (28.6%) with TFEF >4-6 weeks, and 1 009 cases (29.9%) with TFEF >6 weeks. The TFEF in 12 781 cases of VLBW group was 22 (15, 32) d, 439 cases (3.4%) with TFEF ≤1 week, 2 565 cases (20.1%) with TFEF >1-2 weeks, 5 526 cases (43.2%) with TFEF >2-4 weeks, and 4 251 cases (33.3%) with TFEF >4 weeks. The TFEF was 36(23, 52) d of 625 preterm infants at a GA ≤25 weeks and 20 (13, 28) d of 2 606 preterm infants at a GA 31 weeks. Inborn infants had a shorter TFEF than those outborn infants and the infants with breast-fed achieved shorter than formula and mixed feeding both in ELBW and VLBW groups (all P<0.001). The earlier enteral feeding started, the shorter TFEF will be both in ELBW and VLBW groups (both P<0.001). The TFEF of preterm infants who were treated before full enteral feeding like peripherally inserted central catheters, and blood transfusions and blood product providers were all longer than those who were not treated (all P<0.001). The TFEF of preterm infants with complications like hemodynamically significant patent ductus arteriosus, necrotizing enterocolitis, late onset sepsis, severe retinopathy of prematurity and bronchopulmonary dysplasia were all longer than those without (all P<0.001). Conclusions:The distribution of TFEF in VLBW and ELBW has a large difference. The TFEF of preterm infants varies with different GA, treatment measures and complications. Further quality improvement is required to shorten TFEF.

Chronic heart failure （CHF） is the final stage of cardiovascular diseases. It is a complex syndrome， with dyspnea and edema as the main clinical manifestations， and it is characterized by complex disease conditions， difficult cure， and high mortality. Ferroptosis， a new type of programmed cell death， is different from other types of programmed cell death. Ferroptosis is iron-dependent， accompanied by lipid peroxide accumulation and mitochondrial shrinkage， becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi， blood， and body fluid， which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi （heart Qi） is the root cause of CHF， and stagnation （phlegm turbidity and blood stasis） is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine （TCM） plays an important role in the treatment of CHF， improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore， this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation， aiming to provide new ideas and methods for the treatment of CHF with TCM.
