This paper summarizes Professor WANG Xixing's clinical experience in treating immune checkpoint inhibitor-related pneumonitis （CIP） based on the theory of "cough attributed to the five zang （脏） organs". Cough is a common predominant symptom of CIP. According to the theory of "cough attributed to the five zang organs"， drug toxicity triggers cancer toxin， leading to disharmony among the five zang organs， and then lung failing to diffuse and govern descent as the core pathogenesis. Therefore， treatment should focus on harmonizing the five zang organs to restore the normal function of lung qi to diffuse and govern descent. In clinical practice， CIP can be classified into four syndrome patterns， including lung yin depletion， deficiency of both the lung and the spleen with phlegm-dampness， liver fire harassing the lung， and lung-kidney yin deficiency. Correspondingly， Chaimai Jinluo Runfei Decoction （柴麦金络润肺汤） is used to nourish yin and moisten the lung； Qigui Peitu Huayin Decoction （芪桂培土化饮汤） is used to fortify the spleen and tonify the lung， resolve dampness and dispel phlegm； Chaidan Shuyu Runjin Decoction （柴丹疏郁润金汤） is used to drain liver and clear the lung； and Dimai Jinshui Xiangsheng Decoction （地脉金水相生汤） is used to nourish the kidney and moisten the lung.

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.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Aim To explore the effect of age on myocardial remodeling after percutaneous coronary intervention(PCI)in patients with acute anterior myocardial infarction.Methods This study was a cross-sectional study analyzing clinical data of regular follow-up at 1,3,6 and 12 months after PCI for acute anterior myocardial infarction.According to the age of the patients,they were divided into a low age group(＜65 years old)and a high age group(≥65 years old).The differences in baseline data,biochemical indexes,coronary angiography,inflammatory factor levels,and cardiac ultrasound indexes between the two groups were analyzed,and the correlation analysis between age and inflammatory factors and the multivariate linear regression analysis of diastolic function were performed.Results A to-tal of 87 patients with acute anterior myocardial infarction were selected,aged(62±13)years,including 67 males(77.0％),43 in the low age group and 44 in the high age group.Compared with the low age group,the levels of inflam-matory factors such as C-reactive protein,interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)increased in the high age group,while ultrasound indicators such as mitral valve annulus septal e',mitral valve flow velocity E/A,and mitral valve annulus sidewall e'decreased(P＜0.05).Older age was an independent risk factor for a decrease in mitral valve flow velocity E/A,mitral valve annulus sidewall e'and mitral valve annulus septal e'in patients with acute anterior myocardial infarction 6 months after PCI(P＜0.05).Conclusion Age is an independent risk factor for reduced diastolic function after PCI in acute anterior myocardial infarction,inflammatory factor such as IL-1β,IL-6 and TNF-α may play a role in the impaired diastolic function after PCI in age-related acute anterior myocardial infarction.

Aim To apply coronary angiography derived index of microcirculatory resistance(caIMR)to evaluate the effect of coronary microcirculation perfusion on myocardial remodeling after interventional therapy in patients with acute anterior ST segment elevation myocardial infarction(STEMI).Methods This was a cross-sectional study.The analysis was performed among the patients who were hospitalized for acute anterior STEMI in the First Department of the Second Affiliated Hospital of Dalian Medical University from January 2021 to July 2022 and received percutaneous coro-nary intervention(PCI)with regtelar follow-up visits.The patients were divided into low caIMR(L-caIMR)group,me-dium caIMR(M-caIMR)group and high caIMR(H-caIMR)group according to the results of caIMR.The results of ech-ocardiography at perioperative period,1 month,3 months,6 months and 1 year were analyzed and compared,including left atrial diameter(LAD),left ventricular end-diastolic diameter(LVEDD),interventricular septum thickness(IVST),mitral orifice flow velocity E/A,mitral annular septum e'and mitral annular wall e',etc.The difference of interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)and other inflammatory factors in peripheral blood of the three groups were also compared.Results A total of 75 patients diagnosed with acute anterior STEMI were recrui-ted,including 55 males.The L-caIMR group,M-caIMR group,and H-caIMR group had 26,26 and 23 cases,respec-tively.Compared with the L-caIMR group,the LAD and IVST in the M-caIMR group and the H-caIMR group exhibited an increasing tendency one month after PCI,and the increase in the H-caIMR group was more significant than that in the M-caIMR group(P＜0.05).The ejection fraction in the H-caIMR group was notably lower than that in the L-caIMR group and the M-caIMR group at 1 and 3 months after PCI(P＜0.05).Compared with the L-caIMR group,the mitral flow velocity E/A at 6 months after PCI,and the e'at the septal side and the lateral wall of the mitral annulus at 1,3,and 6 months after PCI were significantly reduced in the M-caIMR and H-caIMR groups(P＜0.05).Compared with the L-caIMR group,the levels of IL-1β,IL-6,and TNF-α showed an increasing trend in the M-caIMR group and the H-caIMR group,and the increase was greater in the H-caIMR group than that in the M-caIMR group(P＜0.05).Multivariate anal-ysis revealed that caIMR was a factor influencing the levels of IL-1 β and IL-6(P＜0.05).Conclusion CMD may be involved in the process of myocardial remodeling in patients with acute anterior STEMI after PCI,in which inflammation plays a role.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Objectives:To assess the effectiveness of transcatheter aortic valve replacement (TAVR) on electrocardiographic remodeling in patients with severe aortic stenosis (AS), and identify its influencing factors.Methods:A cohort study was conducted on patients with a confirmed diagnosis of severe AS who successfully underwent TAVR at the Second Affiliated Hospital of Dalian Medical University between June 2018 and March 2023. Data, including standard 15-lead electrocardiograms and echocardiograms, were collected before the operation, 1 week after the operation, and 3 months after the operation. The average degree of ST-segment depression in the lateral wall leads of the electrocardiograms, and the amplitude of the T-wave were measured and calculated. The changes of electrocardiograms indexes were observed, and Spearman correlation analysis was used to explore the correlation between each index of electrocardiograms and each index of echocardiography. Multiple linear regression analysis was used to determine the influencing factors of the improvement of electrocardiographic remodeling in patients with severe AS after TAVR.Results:A total of 33 patients with severe AS, aged (73±9) years, were included in the study. Among them there were 15 (45%) males. The degree of ST-segment depression, supra-aortic flow velocity, peak transaortic pressure, and mean transaortic pressure exhibited significant improvement at 1 week post-TAVR (all P<0.05). Similarly, significant improvements in T-wave hypoplasia or inversion, left ventricular mass, and left ventricular mass index were observed at 3 months post-TAVR (all P<0.05). The degree of ST-segment depression was found to be correlated with supra-aortic flow velocity, peak transaortic pressure, and mean transaortic pressure (all P<0.05). Additionally, a correlation was observed between T-wave amplitude and left ventricular mass, left ventricular mass index, left ventricular end-diastolic internal diameter, and left ventricular ejection fraction (all P<0.05). Multiple linear regression analysis revealed that supra-aortic flow velocity was an independent influencing factor of the level of ST-segment depression ( β=-0.156, P=0.007), while left ventricular mass index was identified as an independent influencing factor of T-wave amplitude ( β=-2.007, P=0.001). Conclusion:The improvement in electrocardiographic remodeling could be observed after TAVR in patients with severe AS, which may be due to enhanced cardiac perfusion and regression of left ventricular hypertrophy subsequent to aortic valve opening.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.
