Objective: To study the association between ankyloglossia and sagittal mandibular development impairment as well as lower anterior dental crowding, providing a reference for clinical practice. Methods: This study was approved by the hospital's Medical Ethics Committee. A total of 100 patients aged 7-13 years were enrolled from January 2024 to January 2025, comprising 50 patients with ankyloglossia (case group) and 50 individuals with a healthy lingual frenulum (normal group). Clinical examination was performed to assess lingual frenulum length, Kotlow classification, and the simplified Hazelbaker assessment tool for lingual frenulum function (HATLFF) score. Cephalometric radiographs were used to measure the A-point-nasion-B-point (ANB) angle, sella-nasion-B-point (SNB) angle, and mandibular total length (condylion-gnathion [Co-Gn]). Dental cast analysis was conducted to evaluate lower anterior teeth crowding. Data were compared between the two groups. Pearson correlation analysis was used to examine the relationships between the lingual frenulum length, simplified HATLFF score, and cephalometric/dental cast parameters (ANB, SNB, Co-Gn, lower anterior crowding). The diagnostic value of ankyloglossia for mandibular development and lower anterior crowding was analyzed using receiver operating characteristic (ROC) curves. Results: Ankyloglossia was significantly associated with mandibular development and lower anterior crowding (P<0.05). The case group showed significantly lower values for the lingual frenulum length, simplified HATLFF score, SNB angle, and Co-Gn, while the ANB angle and lower anterior crowding index were significantly higher compared to the normal group (P<0.05). The lingual frenulum length and simplified HATLFF score were negatively correlated with the ANB angle and lower anterior crowding index, and positively correlated with the SNB angle and Co-Gn (P<0.05). ROC curve analysis indicated that the area under the curve (AUC) for the simplified HATLFF score, and ankyloglossia in predicting mandibular development deficiency and lower anterior crowding was greater than 0.700, demonstrating good diagnostic value. Conclusion A significant correlation exists between ankyloglossia and both mandibular development deficiency and lower anterior crowding.

Objective To analyze the impact of evidence-based reinforcement training and monitoring management on the prevention and control of hospital-acquired multidrug-resistant organism(MDRO)infections.Methods Convenience sam-pling was used to select data from hospitalized patients from 2020 to 2023 in the hospital's medical record system.The control group(pre-management)consisted of 86,564 patients admitted from January 2020 to December 2021,while the intervention group(post-management)consisted of 93,215 patients admitted from January 2022 to December 2023.Routine infection control measures were implemented for the control group,while evidence-based reinforcement training and monitoring management were implemented for the intervention group.The MDRO detection rate,MDRO hospital infection rate,patient antimicrobial drug us-age rate,healthcare workers'adherence to MDRO infection control measures,and MDRO infection control knowledge assessment were analyzed and compared between the pre-and post-management groups.Results After the management intervention,the MDRO detection rate and MDRO hospital infection rate were lower than before the management intervention(x2=4.22,16.078,P＜0.05).The patient antimicrobial drug usage rate decreased(x2=21.387,P＜0.01),while the rate of pathogen testing be-fore antimicrobial drug use increased(x2=9.726,P＜0.05).The healthcare workers'pass rate for MDRO infection control knowledge(96.36％)was significantly higher than before the management intervention(80.00％)(x2=12.654,P＜0.05).The adherence rates for hand hygiene,environmental cleaning and disinfection,isolation signage,single room/bedside isolation,specialized diagnostic and treatment supplies,and implementation of standard precautions increased from 81.82％,80.91％,79.09％,80.00％,77.27％,80.91％to 98.18％,98.18％,96.36％,96.36％,98.18％,98.18％(x2=16.364,17.528,15.240,14.132,22.334,17.528,P＜0.05).Conclusion Evidence-based reinforcement training and monitoring management can effectively reduce the MDRO detection rate and hospital infection rate,promote rational antimicrobial drug use,and improve the quality of medical care.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the molecular mechanism of dexmedetomidine(Dex)protecting ischemia/reperfusion(I/R)myocardium.Methods:Wild type mice were grouped into control(Control)group,sham operation(Sham)group,WT I/R group,WT Dex group,and Dectin-1 knock out mice were grouped into KO I/R group and KO Dex group in the in vivo study(n=6).TTC stain-ing was used to determine the myocardial infarction area(%)of the above six groups of mice.HE staining and pathological analyze was used to determine the myocardial injury.Serum TNF-α,IL-6 and IL-10 levels in mice were detected by ELISA.Flow cytometry(FCM)was used to count and sort of infiltrating M2 macrophages and neutrophils in myocardium.qPCR assay was used to determine the Dectin-1 mRNA expression in the above sorted cells.Results:TTC results showed that there was no myocardial infarction in the mice of Control group and Sham group.Compared with the WT I/R group,the infarct volume was significantly lower in WT Dex group,KO I/R group and KO Dex group(P<0.05).Compared with the KO I/R group,the infarct volume was reduced in KO Dex group(P<0.05).The results of HE staining showed that the myocardial fibers of the WT I/R group of mice were disorderly arranged,with a large number of broken myocardial fibers,while the myocardial fibers of the WT Dex group,KO I/R group and KO Dex group of mice had a little breakage,the structural damage was not significant,and the myocardial arrangement was relatively neat.The degree of myocardi-al injury of mice in KO Dex group were less than that in KO I/R group mice.ELISA results showed that compared with Sham group,the serum TNF-α and IL-6 levels of the mice in WT I/R group were significantly increased,and the IL-10 level was significantly de-creased.Compared with WT I/R group,serum TNF-α and IL-6 levels of the mice in WT Dex group and KO I/R group were significant-ly decreased,and IL-10 level was significantly increased.Compared with KO I/R group,the serum TNF-α and IL-6 levels of the mice in KO Dex group were significantly decreased,and the IL-10 level was significantly increased(P<0.05).FCM cell counting results showed that compared with Sham group,a large number of M2 macrophages and neutrophils were infiltrated in the myocardium of WT I/R group of mice(P<0.05).Compared with WT I/R group,the M2 macrophages and neutrophils infiltrated in the myocardium were significantly decreased in WT Dex group,KO I/R group and KO Dex group of mice(P<0.05).While there was no significant differ-ence between the KO I/R group and the KO Dex group mice(P>0.05).qPCR results showed that compared with Sham group,the ex-pression level of Dectin-1 mRNA in the myocardial infiltrated M2 macrophages and neutrophils were significantly up-regulated in WT I/R group of mice(P<0.05).While compared with WT I/R group,the expression level of Dectin-1 mRNA in Dex group of mice was sig-nificantly lower(P<0.05).Mice in KO I/R group and KO Dex group did not express Dectin-1.Conclusion:The protective mecha-nisms of Dex preconditioning on I/R injured myocardium involves reducing the infiltrating number of M2 macrophages and neutrophils in myocardium after I/R injury,which may be achieved by inhibiting the expression of Dectin-1.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective:To investigate the clinical effect of thin superficial inferior epigastric artery flaps in repairing soft tissue defects after buccal cancer surgery.Methods:From January 2018 to October 2019, 6 patients with buccal cancer who underwent surgery were constructed with thin superficial inferior epigastric artery flaps, including 2 males and 4 females, aged 43 to 68 years, with an average of 61.5 years. Doppler ultrasound was utilized of all patients to design flap preoperatively . According to the size of the affected area defect, according to the shape and direction of the blood vessels, a thin superficial inferior epigastric artery flap was elevated above the Scarpas fascia layer and transferred to repair soft tissue defects after buccal cancer surgery. The survival and functional recovery of the flap were observed.Results:All 6 flaps survived. The superficial inferior epigastric artery flaps ranged from 5.0 cm×7.0 cm to 7.0 cm×9.0 cm. The thickness of the flaps ranged from 0.5 cm to 1.3 cm, and the average thickness was 0.8 cm. The pedicle length is 6.0-9.0 cm.Four of them anastomosed to the superficial inferior epigastric veins and companion vein, 2 cases only anastomized superficial inferior epigastric veins . The follow-up period ranged from 3 to 12 months, with an average of 10 months. The cheek shape was good, the mouth opening was normal, there was no obvious bloating, and no secondary surgery was required. Linear scars were left on the donor site, with concealed location and no impairment of abdominal wall function.Conclusions:The donor site of the thin superficial inferior epigastric artery flap is small, the scar is concealed, the cheek is not bloated, and the opening degree of mouth is satisfactory. It is a good choice for reconstructing postoperative defect of cheek cancer.
