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.

The Shanghai-style pediatric Tuina(Chinese therapeutic massage)school,a renowned academic school of pediatric Tuina in China,was founded by Professor JIN Yicheng,a mentor of the National Senior Traditional Chinese Medicine(TCM)Experts'Clinical Experience Inheritance Class and a distinguished TCM practitioner in Shanghai.This academic school has now been perpetuated through four generations.Prof.JIN Yicheng,a pioneering leader in modern China's pediatric Tuina,has dedicated sixty years to medical practice with unwavering benevolence and adherence to"principled innovation".While delving into traditional and ancient teachings,he has also embraced contemporary advancements.Building upon the essence of traditional pediatric Tuina,he integrated distinctive techniques from various Tuina schools,including the Yi Zhi Chan Tuina school,rolling manipulation Tuina school,and Neigong Tuina school.He also assimilated the quintessence of historical pediatric Tuina literature,the experience of modern Shanghai-based pediatric Tuina masters,and folk techniques while incorporating his years of clinical insights.This synthesis finally led to the formulation of the academic thought of"reinforcing healthy Qi and unblocking regulation"in Shanghai-style pediatric Tuina that guides clinical practice.Specifically,he comprehensively applies techniques such as"unblocking regulation of Zang-Fu organs","unblocking regulation of the four seas","unblocking regulation of the water and fire",and"unblocking regulation of the back"to the prevention and treatment of pediatric diseases across internal medicine,external medicine,orthopedics,and otolaryngology,which has significantly enhanced clinical efficacy and expanded the applicable age range and scope of Tuina for pediatric health issues,more aligning with the characteristics of children and adolescents'health challenges and current clinical demands,and paving a new way in preserving and developing traditional pediatric Tuina.

Objective:To summarize and analyze the clinical characteristics and treatment outcomes of patients with recurrent pericarditis.Methods:This observational study consecutively recruited patients with recurrent pericarditis who were hospitalized at Peking University People′s Hospital between January 2017 and February 2024. Clinical characteristics and treatment outcomes were collected and summarized during follow-up.Results:A total of 8 recurrent pericarditis patients including 3 males were included, with an age of 34.0 (22.0, 39.5) years. In terms of clinical features, all patients presented with acute-onset severe chest pain, accompanied by fever in 7 and an audible pericardial friction rub in 2 patients. Electrocardiogram showed no diffuse ST-segment elevation or PR-segment depression in any patient. Echocardiography revealed pericardial effusion in all cases, with extensive fibrinous exudate and transient pericardial thickening observed in 6 patients. CT identified concurrent pleural and/or peritoneal effusions in 6 patients. All patients exhibited marked elevations in C-reactive protein, erythrocyte sedimentation rate and D-dimer levels. Whole-exome sequencing identified MEFV gene mutations associated with familial Mediterranean fever in 3 cases. Two patients developed cardiac tamponade requiring pericardiocentesis, which revealed hemorrhagic effusion. In the aspect of treatment outcomes, the time from recurrence to first confirmed diagnosis of recurrent pericarditis of this cohort was 14.5 (13.3, 19.5) d. Upon diagnosis, all patients promptly received standard anti-inflammatory therapy with ibuprofen and colchicine, achieving rapid relief. However, during a follow-up of 12.0 (6.0, 25.3) months, 3 patients experienced recurrence, and 2 developed transient constrictive pericarditis.Conclusion:Patients with recurrent pericarditis typically exhibit characteristic clinical presentations, laboratory abnormalities, imaging findings and potential genetic associations. Although standard anti-inflammatory therapy demonstrates favorable short-term efficacy, long-term management remains challenging due to the risks of recurrence and progression to constrictive pericarditis.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective:To assess the effects of nutritional interventions combined with Traditional Chinese Med-icine(TCM)physical dialectics on the development of gestational diabetes mellitus(GDM),dietary status during pregnancy,and maternal and infant outcomes in high-risk pregnant women in early pregnancy.Methods:298 high-risk pregnant women with GDM in early pregnancy(gestational week≤14 weeks)registered in the Obstet-rics Department of Urumqi Maternal and Child Health Hospital from 1st December 2022 to 30th March 2023 were selected as the study subjects and randomly divided into the intervention group(149 cases)and the control group(149 cases).During 14 to 23+6 weeks of pregnancy,TCM constitution nutritional intervention was carried out for pregnant women in the intervention group,and routine guidance and healthy dietary education was carried out in the control group.The incidence of GDM in the two groups was compared at 24-28 weeks of pregnancy,and the relationship between early pregnancy nutritional intervention combined with TCM constitution and the risk of GDM was analysed in subgroups using logistic regression and likelihood ratio test.The dietary situation,biochemical in-dexes and delivery outcomes after the intervention were compared at 32-36 weeks of pregnancy.Results:①The incidence of GDM in the intervention group was significantly lower than that in the control group(14.09％vs.23.49％,P＜0.05).The effect of the TCM constitution based nutritional intervention on the risk probability of GDM was statistically significant only among pregnant women with different ranges of gestational weight gain(GWG)(P=0.018).Among them,pregnant women with GWG lower than the recommended range had a reduced risk of GDM after intervention(OR 0.27,95％Cl 0.10-0.68,P=0.008).② After intervention,the evaluation index of di-etary balance index of pregnant women in the intervention group was better than that of the control group(P＜0.05),and the intake of cereals and potatoes,vegetables,and water of pregnant women in late pregnancy in the intervention group was higher than that of the control group(P＜0.05).③The levels of triglycerides,total choles-terol,low-density lipoprotein,glycated haemoglobin,uric acid and creatinine of pregnant women in the intervention group were lower than those of the control group in late pregnancy(P＜0.05).GWG,gestational age at delivery,the rate of low-birth-weight,and the neonatal 1-minute Apgar scores were all better than those of the control group(P＜0.05.Conclusions:Nutritional interventions in early pregnancy combined with TCM constitution can sig-nificantly reduce the incidence of GDM in high-risk pregnant women and the chances of low-birth-weight babies.Obstetrics outpatient clinics can actively develop extensive collaboration with TCM and clinical nutrition depart-ments to reduce adverse pregnancy outcomes for both mother and fetus.
