Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Breast cancer is the most common malignancy among women worldwide and significantly impacts patients'quality of life.With advancements in medical technology,treatment strategies for breast cancer are increasingly shifting toward precision and minimally invasive approaches.High-intensity focused ultrasound(HIFU),characterized by its non-invasive and non-ionizing nature,has been widely applied in the treatment of various benign and malignant tumors.HIFU holds great potential in breast cancer therapy,demonstrating significant antitumor effects in thermal ablation,chemotherapy,immunotherapy,and targeted therapy combinations.HIFU not only ablates tumor tissue and activates antitumor immune responses,but also,when combined with drugs,enhances therapeutic efficacy,promotes drug accumulation in tumor tissues,reduces side effects,and improves long-term outcomes.This article reviews the application of HIFU in the treatment of breast cancer,providing a reference for clinical practice and research.

Objective To evaluate the diagnostic value of prostate health index(PHI)and prostate health index density(PHID)in identifying intermediate-to high-risk prostate cancer(PCa).Methods Clinical data of 160 treatment-na?ve patients with highly suspected PCa,who underwent initial prostate biopsy in our hospital during Jul.2022 and Feb.2024,were retrospectively analyzed.Data included age,body mass index(BMI),prostate volume(PV),total prostate-specific antigen(tPSA),free PSA(fPSA),[-2]proPSA(p2PSA),PHI and PHID.Biopsy-positive results were stratified according to the EAU D'Amico risk criteria.Receiver operating characteristic(ROC)curve and multivariate logistic regression analysis were employed to assess the diagnostic performance of PHI and PHID in predicting PCa and identifying intermediate-to high-risk PCa.Results There were statistically significant differences in tPSA,p2PSA,PHI and PHID between the negative and positive groups,as well as among the low-,medium-and high-risk groups(P＜0.01).Both PHI and PHID demonstrated good diagnostic performance in predicting PCa(AUC=0.820 8 and 0.875 7,respectively;all P＜0.001),and in identifying intermediate-to high-risk PCa(AUC=0.838 0 and 0.878 3,respectively;all P＜0.001).Compared to the baseline model,the incorporation of PHI and PHID individually into the multivariate model significantly improved the screening performance for PCa(AUC=0.910 and 0.898,respectively;all P＜0.001).Conclusion PHI and PHID exhibit high diagnostic efficacy in screening PCa,particularly in identifying intermediate-to high-risk disease.

Objective To explore the therapeutic effect and mechanism of electroacupuncture on depressive model mice based on the phosphatase and tensin homolog-induced kinase 1(PINK1)/Parkin pathway.Methods Specific pathogen-free grade male C57BL/6J mice were used.For experiment 1,60 mice were randomly divided into blank,model,sham electroacupuncture,and electroacupuncture groups using the random number table method,with 15 rats per group.For experiment 2,30 mice were randomly divided into normal,cyclosporine A(CsA),and electroacupuncture+CsA groups using the same method,with 10 rats per group.The chronic restraint stress(CRS)was used to establish a depression model.After successful modeling,CRS was continued to maintain model stability.After modeling,1 h before daily CRS stimulation,the electroacupuncture and electroacupuncture+CsA groups received electroacupuncture interventions at the"Baihui"(GV20)and"Zusanli"(ST36)acupoints,using continuous wave stimulation at a frequency of 2 Hz and an intensity of 1 mA for 20 min,once daily for 7 consecutive days.Mice in the sham electroacupuncture group received superficial needling at non-meridian,non-acupoint locations under the axilla 1 h before CRS,with the electroacupuncture device connected but not powered on once a day for 7 consecutive days.Mice in the CsA and electroacupuncture+CsA groups received an intraperitoneal injection of CsA solution(0.2 mg/g)30 min before electroacupuncture intervention,once daily for 7 consecutive days.In experiment 1,depressive-like behavior was assessed using the open field,tail suspension,and sucrose preference tests.The spontaneous excitatory postsynaptic currents(sEPSC)and spontaneous inhibitory postsynaptic currents(sIPSC)parameters of hippocampal neurons were evaluated using brain slice patch clamp techniques.Western blotting was conducted to measure the expression levels of mitochondrial autophagy-related proteins PINK 1,phosphorylated PINK1(p-PINK1),Parkin,microtubule-associated protein 1A/1B-light chain 3-Ⅱ/Ⅰ(LC3-Ⅱ/Ⅰ),ubiquitin-binding protein(p62),and mitochondrial markers,including translocase of outer mitochondrial membrane 20(TOMM20),heat shock protein 60(HSP 60),and cytochrome c oxidase Ⅳ(COX Ⅳ).Immunofluorescence was used to detect PINK1 protein expression in the CA3 region of the hippocampus.Transmission electron microscopy was used to examine the ultrastructure of mitochondria in hippocampal neurons.On the basis of experiment 1,experiment 2 evaluated depressive-like behavior in mice using sucrose preference,open field,and tail suspension tests;Western blotting was used to detect the expressions of PINK1,p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,p62,TOMM20,HSP 60,and COX Ⅳ proteins of hippocampus in mice.The mitochondrial ultrastructure was observed in hippocampal neurons using transmission electron microscopy.Results In experiment 1,compared with the blank group,the model and sham electroacupuncture groups exhibited a decrease in sucrose consumption rate,a decrease in the time spent in the center area,a reduced proportion of distance moved in the center area,and an increase in immobility time of tail suspension(P＜0.05).The sEPSC and sIPSC in hippocampal neurons decreased in both amplitude and frequency(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COXⅣ expression levels in the hippocampus were reduced,whereas the p62 expression level was increased(P＜0.05).The average fluorescence intensity of PINK1 in the CA3 region of the hippocampus decreased(P＜0.05).The number of healthy mitochondria in hippocampal neurons was reduced,with numerous damaged mitochondrial structures observed.Compared to the model and sham electroacupuncture groups,the electroacupuncture group showed an increased in the time spent in the center area,a higher proportion of distance moved in the center area,and an elevated sucrose consumption rate.In contrast,the immobility time in the tail suspension test decreased(P＜0.05),whereas the amplitude and frequency of sEPSC and sIPSC in hippocampal neurons increased(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COXⅣ expression levels in the hippocampus increased,whereas the p62 expression level decreased(P＜0.05).The average fluorescence intensity of PINK1 in the CA3 region of the hippocampus increased(P＜0.05).Additionally,mitochondrial damage in hippocampal neurons was alleviated,and a notable presence of autophagosomes mitophagy lysosomes was observed.In experiment 2,compared with the normal group,the mice in the CsA and electroacupuncture+CsA groups showed a decrease in the time spent in the center area and the proportion of distance moved in the center area,a decrease in sucrose consumption rate,and an increase in the immobility time in the tail suspension test(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COX Ⅳ expression levels in the hippocampus decreased,whereas p62 expression increased(P＜0.05).Many damaged mitochondria were observed in hippocampal neurons.Conclusion Electroacupuncture may exert its antidepressant effects by promoting PINK1/Parkin pathway-mediated mitophagy to eliminate damaged mitochondria,thereby restoring the function of hippocampal neurons in depressive model mice.
