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.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To investigate the current status of off-label drug use(OLDU)management in tertiary hospitals of Guizhou province and to provide baseline evidence for developing a unified administration regulation for OLDU in Guizhou province.Methods In line with the relevant policies and regulations,a questionnaire including basic information about the person filling out the form,basic information about the hospitals,and information about OLDU was developed.The questionnaire was sent to 84 tertiary hospitals in Guizhou province through the Wenjuanxing.Results A total of 84 questionnaires were distributed and recovered,with a response rate of 100.00%.Of the 84 hospitals,77 had OLDU,of which 68(88.31%)had established a management system for OLDU.Among the 77 hospitals with OLDU,65(84.42%),42(54.55%),58(75.32%),36(46.75%),15(19.48%),and 21(27.27%)hospitals respectively,required approval from the Committee on Drug Administration and Pharmacotherapy before OLDU,restricted the qualifications of doctors prescribing OLDU,required informed consent from patients or their families before OLDU,recorded the matters and reasons in the medical records of patients treated with OLDU,followed up patients in their files and evaluated the reasonableness of the OLDU,and carried out special reviews for OLDU.Only 30(38.96%)hospitals have set up a catalogue of OLDUs,and 58(75.32%)hospitals have urgent needs to set up a unified provincial catalogue of OLDUs.Conclusion The pharmacy administration level of OLDU in tertiary hospitals of Guizhou province is relatively low,so there is an urgent need to establish a unified OLDU management system and medication catalog.

Objective:To deeply explore the pain experience of patients with rheumatoid arthritis, so as to provide a basis for the practical interventions in the next step.Methods:Using the phenomenological research method, 18 patients with rheumatoid arthritis who experienced pain in the First Hospital of Soochow University from September 2020 to January 2021 were selected for semi-structured interviews, and the Colaizzi 7-step analysis method was used for data analysis.Results:The pain experience of patients with rheumatoid arthritis were summarized into six themes. Pain was complex and erratic, pain relief strategies were ineffective, pain negatively affected daily life, expected more pain relief, seeking help selectively when pain occurs, and experienced pain brings positive change.Conclusions:Medical staff must pay attention to the real experiences and demands of pain in rheumatoid arthritis patients, use information technology and multidisciplinary collaboration to provide patients with effective pain management strategies and encourage patients to make more positive changes to relieve pain symptoms.

Objective:To investigate of AIDET communication model in caring for type 2 diabetes mellitus of hospitalized patients.Methods:A total of 113 patients with type 2 diabetes mellitus treated in our department from January 2018 to November 2019 were enrolled, and divided into the control group(receiving a conventional communication mode)and the observation group(receiving an AIDET communication mode)according to a time order in the selecting of the research patients.The changes of self-care behavior and glucose metabolism index were evaluated and analyzed between the two groups.Results:On admission, the fasting blood glucose, 2-h postprandial blood glucose and glycosylated hemoglobin were(9.1±1.7)mmol/L, (13.8±2.9)mmol/L and(8.4±3.5)% in the observation group, and(9.4±2.1)mmol/L, (14.1±3.2)mmol/L and(8.1±2.9)% in the control group, respectively, with no statistically significances( P>0.05).

The scores of management of poor blood glucose, foot care, blood glucose monitoring, medication compliance, regular exercise and diet control were higher in the observation group than in the control group at discharge( P<0.05). Conclusions:The application of AIDET communication mode can effectively enhance the self-care behavior of patients and help improve the glucose metabolism in hospitalized patients with type 2 diabetes mellitus.It has very positive effects on controlling the development of type 2 diabetes mellitus and improving the quality of life.

Objective:To explore the safety and clinical value of ultrasound-guided percutaneous core needle biopsy in the diagnosis of cardiac intermural tumors and pericardial tumors.Methods:Seven patients who underwent ultrasound-guided percutaneous cardiac tumors needle biopsy in Fujian Provincial Hospital from January 2012 to December 2019 were selected for this study. The locations and sizes of the lesions were recorded preoperatively by echocardiography and the operation time was recorded by conventional ultrasonography. The postoperative complications was followed up, and the satisfaction of pathological materials was used as the evaluation standard to comprehensively analyze the safety and clinical application value of ultrasound-guided percutaneous biopsy in the diagnosis of cardiac tumors.Results:Ultrasound-guided percutaneous biopsy was performed successfully in all the 7 cases, 3 of them were intermural tumors and 4 of them were pericardial tumors. Except for 2 patients with diffuse pericardial space, the maximum diameter of the remaining 5 patients was (58.6±23.5)mm. Six cases were punctured from the apex of the heart, and 1 case from the left parasternal through third intercostal space toward the bottom of the heart as the needle pathway. The satisfaction of pathological material was 100%, and the time of procedure was (15.1±3.3)min. There were no postoperative complications such as bleeding, infection or arrhythmia.Conclusions:Ultrasound-guided percutaneous transthoracic needle biopsy is safe and feasible, which provides a simple and easy method for the biopsy of cardiac intramural tumors and pericardial tumors.

Objective To understand the infected strains and prevalence of brucellosis in occupational population in Tacheng and Kashgar regions,Xinjiang Uygur Autonomous Region.Methods In September 2015,blood samples from occupational population (including herders,semi-agricultural and semi-pastoral,veterinarians) and non-occupational population (including students and cadres) were collected to detect Brucellaspecific antibody and bacterial nucleic acids by rose bengal plate test (RBPT),serological standard tube agglutination test (SAT) and PCR methods,respectively.The positive products of PCR were sent to Shanghai Sangon Biotechnology Co.,LTD.Then the sequence results were retrieved online using the basic alignment search tool (BLAST) in GenBank web page and uploaded to NCBI (National Center for Biotechnology Information).Results A total of 546 blood samples were tested,including 300 males,aged (55-± 15) years old,and 246 females,aged (54 ± 12) years old.The positive rates were 17.58％ (96/546) and 6.78％ (37/546) in 546 blood samples by serological method and genetic markers targeting omp22 and omp2,respectively.The positive rates were statistically significant (x2 =29.8,P ＜ 0.05).Additionally,based on BLAST analysis of outer membrane protein omp22 and omp2 genes,the positive products were identified as Brucella abortus,and the sequence similarity was 100.00％ (253/253,863/863 bp) to Brucella abortus strain Wisconsin genome assembly,chromosome (LT651712).Conclusions Brucellosis has a high infection rate in the occupational population of some animal husbandry-based groups in Xinjiang.The infection strain is abortive species Brucella,and health education for the occupational population and prevention of brucellosis should be strengthened to reduce the infection rate.

OBJECTIVETo investigate the safety and clinical significance of pelvic floor reconstruction in extralevator abdominoperineal excision(ELAPE) for advanced low rectal cancer.

METHODSThe clinical efficacy was retrospectively analyzed in 30 patients with low rectal cancer who underwent ELAPE from January 2013 to December 2016 in Nanjing Drum Tower Hospital, the affiliated Hospital of Nanjing University Medical School. There were 21 male patients and 9 female, with an average age of 61.7 years old. We used 13*15 cm Biodesign biologic meshes(Cook, China) for the reconstruction and the procedure involved soaking in saline solution for 5 minutes and fixation of the mesh to the cut edges of the levators by non-absorbable 2-0 sutures. A perineal drain was used and was removed when drainage was minimal. Potassium permanganate was used for hip bath after removing the stitches. The surgical procedure, postoperative complications, prognosis and follow-up of all these patients were documented.

RESULTSThe operations of all patients were completed successfully. ELAPE could remove more para cancer tissues in the distant rectum. There was no rectum perforation, and the circumferential resection margins of all specimens were proved to be negative. During the follow-up of 21 months, only 2 patients suffered incision infection and healed uneventfully after strengthening the dressing. No one developed perineal breakdown, bulge or intestinal obstruction, as well as local recurrence and pelvic floor hernia. There was also no complication related to mesh. The average hospitalization time was 10 days (9-15 days).

CONCLUSIONSThe ELAPE could render a low occurrence of intraoperative perforations and circumferential resection margins. Reconstruction of pelvic floor with biologic meshmight lower the complication incidences associated with the perineal region.

This study aimed to investigate the prevalence and molecular characteristics of Listeria monocytogenes in cooked products in Zigong City, China. The overall occurrence of the L. monocytogenes in the ready-to-eat (RTE) shops and mutton restaurants surveyed was 16.2% (141/873). An occurrence of 13.5% was observed in RTE pork, 6.5% in RTE vegetables, and more than 24.0% in either cooked mutton or cooked haggis. Serotype 1/2b (45.4%), 1/2a (33.3%), and 1/2c (14.2%) were the predominant types. By comparing the clonal complexes (CCs) based on multilocus sequence typing (MLST) of the L. monocytogenes from cooked foods in Zigong City and 33 listeriosis cases from different districts of China, CC87, CC9, CC8, and CC3 were showed to be prevalent in cooked products and CC87 and CC3 were the first two frequent types in the 33 clinic-source strains. All CC87 stains harbored the newly reported Listeria pathogenicity island 4 (LIPI-4) gene fragment ptsA, and all CC3 strains possessed the Listeria pathogenicity island 3 (LIPI-3) gene fragment llsX. These may increase the occurrence of the strains belonging to CC87 and CC3 in listeriosis cases in China and also underline the risk of infection owing to the consumption of the cooked products from Zigong. ST619 (serotype 1/2b) harbored both llsX and ptsA, indicating a potential hypervirulent sequence type in Zigong.
