OBJECTIVE To construct an evaluation index system for the core competencies of ethics committee members of drug clinical trial institution， providing a basis for optimizing the training system for committee members， improving the quality of ethical review， and fully safeguarding the safety and rights of subjects. METHODS Using methods such as literature research and expert consultation， a preliminary core competency evaluation index system was constructed. The Delphi method was employed to revise and validate it， ultimately forming an evaluation index system for the core competencies of ethics committee members. Based on this system， a questionnaire survey was conducted among 90 ethics committee members from 29 drug clinical trial institutions nationwide， comparing their importance rating and self-assessment scores of the core competency indexes. RESULTS The evaluation system constructed included 4 primary indicators （ethics and professional knowledge， ethics review ability， communication and expression ability， moral integrity and work style） and 39 secondary indicators （familiarity with the content of clinical trial-related laws and regulations， ability to complete project ethics review and identify ethical defects in research protocols within a short period of time， ability to judge the scientific value of clinical research， etc.）. The results of questionnaire survey showed that the interviewed ethics committee members had significant capability gaps in dimensions such as regulatory knowledge， ethical norms， review efficiency， risk judgment， and problem analysis. The differences between the importance rating scores of corresponding secondary indicators and the self-assessment scores were all no less than 0.38. CONCLUSIONS This study has developed a quantifiable and stratified core competency assessment tool for ethics committee members. It can provide a scientific framework for committee member training， qualification certification， and standardized management of ethics committees.

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.

OBJECTIVE To establish a core competency evaluation system for drug clinical trial quality management personnel in China and validate its application. METHODS Based on the scope of work， responsibilities， and role positioning of quality management personnel in drug clinical trials， a preliminary draft of the core competency evaluation system was constructed through literature analysis and expert consultation. The draft was refined through a Delphi method involving 17 experts who provided feedback and revisions， ultimately forming a complete evaluation system. The developed system was applied to conduct electronic surveys from March to May 2024 among 110 quality management personnel from 38 drug clinical trial institutions， comparing their scores on indicator importance and self-assessed capabilities. RESULTS The response rate of both rounds of questionnaire survey was 100%， with Kendall’s W coefficients of 0.256 and 0.277 （P＜0.001 for both）， and an expert authority coefficient of 0.946. The finalized evaluation system for core competencies of clinical trial quality management personnel comprised 9 primary indicators， covering individual professional competence， communication skills， implementation condition verification， informed consent process review， clinical trial execution monitoring， adverse event disposal， reporting and documentation， trial record examination， trial report auditing， and inspection of other tasks， and 107 secondary indicators. Empirical research revealed significant discrepancies between importance scores and self-assessed competency scores across 70 indicators among 110 respondents （P＜0.05）. Indicators with relatively notable gaps between importance scores and self-assessed competency scores included in-depth understanding of Good Clinical Practice （GCP） requirements （0.34-point gap）， familiarity with national and institutional clinical trial inspection priorities （0.24-point gap），etc. CONCLUSIONS The indicator system constructed in this study has good scientificity and reliability. Clinical trial quality management personnel demonstrate deficiencies in multiple critical competencies， highlighting the urgent need for targeted training programs to enhance their overall professional capabilities.

Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.

Objective:To explore the clinical characteristics of poisoned patients with poisons purchase online.Methods:A retrospective case-control study was conducted on poisoned patients purchased poisons online from 1st January 2021 to 31th May 2022 in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University. The clinical data including sex, age, way of medical treatment, cause of poisoning, exposure routes, category of toxic drugs, gastric lavage, toxic detection and prognosis of patients were collected and compared with those patients obtained poisons at stores as the control group.Results:Totally 318 poisoned patients were included in this study, of which 44 (13.8%) were obtained poisons online. Compared with the patients obtained poisons at stores, the patients obtained poisons online were younger ( P<0.001), and had higher proportion of suicide intention ( P=0.006), more oral route exposure ( P=0.029), and more proportions of receiving gastric lavage before transfer to the hospital ( P=0.001). Pesticides and fertilizers with organic heterocycles were the main types of poisons in the online group, and there was no statistical difference in the distribution of poisons compared with the control group. Mixed drug poisoning was the leading cause in both online group (27.8%) and control group (38.8%) in drug overdose poisoned types, followed by dextromethorphan (16.7%) and estazolam (15.5%) in the online group. Conclusions:Young people are the main group getting poisons through the Internet. Health education should be strengthened for this group, and online shopping platforms should pay attention to the poisoning risk of potential overdose drugs or poisons transactions.

The clinical data of a case with late-onset isolated sulfite oxidase deficiency(ISOD)admitted in the Department of Neurology, Children′s Hospital, Zhejiang University School of Medicine in July 2021 were retrospectively analyzed.Fifteen previously published cases of late-onset ISOD were also reviewed.The patient was a girl, who was hospitalized because of " motor regression with mental retardation for 5 days" at 1 year old.The manifestations of the patient were extrapyramidal symptoms, regression of motor development and seizures.The level of urinary sulfites in the patient was increased.Magnetic resonance imaging (MRI) features were bilateral pallidus and substantia nigra.Gene sequencing suggested a pure missense mutation of the sulfite oxidase( SUOX) gene c. 650(exon5)G>A(p.Arg217Gln). In 16 cases of late-onset ISOD, the median age at onset and diagnosis was 10.5 months and 34.0 months, respectively.The common clinical manifestations were hypotonia (13 cases), seizures (10 cases), movement disorders (9 cases), and ectopia lentis (6 cases). The most common brain MRI feature was pallidus changes (11 cases), followed by lesions of substantia nigra (5 cases), and cerebral atrophy (4 cases). Fourteen cases of late-onset ISOD showed a positive urinary sulfite test.The missense mutation of the SUOX gene was found in 9 cases.It suggested that brain MRI involvement of bilateral pallidus, high excretion of urine sulfites and the missense mutation of the SUOX gene were important diagnostic clues for late-onset ISOD.

Objective:To analyze the results of surgical treatment in patients with obstructed total anomalous pulmonary venous connection.Methods:Inclusion criteria: Patients with obstructed total anomalous pulmonary venous connection, who underwent surgical treatment in our hospital between December 2012 to January 2018. Exclusion criteria: (1)With complicated malformations, such as single ventricle and visceral inversion; (2)The maximum flow velocity of pulmonary vein was less than 1.2 m/s; (3)Had not underwent surgery. 57 patients[33 males and 24 females, age: (3.2±1.7) months, weight: (5.0±0.9) kg] were enrolled. There were four anatomical subtypes: supracardiac type(n=30), cardiac type(n=16), infracardiac type(n=5), and mixed type(n=6). Patients were followed up after operation.Results:During the follow-up of(52±21) months, 8 cases(14.0%, 8/57) died postoperatively. Postoperative pulmonary vein stenosis was present in 7 patients(12.3%, 7/57). The mortality of patients with postoperative pulmonary vein stenosis(57.1%, 4/7) was significantly higher than that of patients without postoperative pulmonary vein stenosis(8.0%, 4/50).Conclusion:The results of surgical treatment in patients with obstructed total anomalous pulmonary venous connection were encouraging, however, recurrent pulmonary venous stenosis still should be taken care.
