Objective To investigate and establish thyroid function reference range during 3 pregnant stages in Chaoshan area:thyrotropin (TSH),free thyroxin (FT4).Methods 863 healthy pregnant women visited antenatal clinic in the Second Affiliated Hospital were included in this study.By detecting serum levels of TSH,FT4,thyroglobulin antibody (TgAb),and thyroid peroxi-dase antibody (TPOAb)in these women,the euthyroid reference ranges of serum TSH and FT4 in different pregnant stages were established based on the standards of the United States National Institute of Clinical Biochemical (NACB)guidelines.Results The ranges of serum TSH in the first,second and third trimester of pregnancy were 0.13-3.93 mIU/L,0.14-4.55mlU/L,and 0.42-3.85 mIU/L,respectively.The ranges of serum FT4 levels in these 3 stages were 12.00-23.34 pmol/L,6.27-12.65pmol/ L, and 9.80-18.20 pmol/L,respectively.The range of serum TSH levels in our study were similar with the reference range recom-mended by the guidelines in China,but were different compared with the American Thyroid Association (ATA)guidelines.Conclu-sion TSH,FT4 levels show dynamic changes during different stages of pregnancy.The thyroid function ranges of healthy pregnant women in Chaoshan area are quite different compared with non-pregnant population and pregnant women in distinct area.Due to the differences of diet,iodine intake,economy and culture in Chaoshan area,regional thyroid function reference ranges specific for differ-ent stages of pregnant women should be established.

The shoulder joint is the most prone to dislocation in the whole body, and more than 95% of them are anterior dislocation. Improper treatment after the initial dislocation is easy to lead to recurrent anterior dislocation or anterior shoulder instability, and the outcomes following conservative treatment is poor. Anterior shoulder instability can damage the soft tissue structure and bone structure that maintain the stability of shoulder joint, among which bone structure is the most important factor affecting the stability of shoulder joint. Diagnosis should be combined with medical history, physical examination, and auxiliary examination. Currently, three-dimensional CT is the most commonly used auxiliary examination means. However, various bone defect measurement and preoperative evaluation methods based on three-dimensional CT and the glenoid track theory have their own advantages and disadvantages, and there is still a lack of gold standard. Currently, the mainstream treatment methods mainly include Bankart procedure, coracoid process transposition, glenoid reconstruction with free bone graft, Bankart combined with Remplissage procedure, and subscapular tendon binding tamponade, etc. Each of these procedures has its own advantages and disadvantages. For the diagnosis and treatment of anterior shoulder instability, there are still too many unknown, further research and exploration need to be studied.

Objective:To investigate psychological resilience of inpatients with extracranial arteriovenous malformation (AVM) and analyze the related factors, in order to provide scientific basis for improving the psychological resilience of patients.Methods:A cross-sectional study was conducted to include patients with extracranial AVM who were hospitalized in the Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from October 2020 to December 2021. The general information questionnaire, Cornor-Davidon resilience scale, Herth hope index, medical coping modes questionnaire and family APGAR scale were used to investigate them. SPSS 21.0 software was used. The t-test, one-way ANOVA, Pearson correlation analysis and multiple linear regression analysis were used for statistical analysis. Results:In total, 177 patients with extracranial AVM were included in our study. The total mean score of the resilience scale was 65.94±13.90, and the mean scores of the three dimensions of resilience, optimism and strength were 33.02±7.67, 10.38±2.75 and 22.54±4.67. The mean scores of Herth hope index was 37.50±3.56, positive coping style was 24.89±6.65, and family APGAR scale was 8.19±2.41. In univariate analysis, gender, ethnicity and family relationship had significant differences in psychological resilience (all P<0.05). Among these patients, female’s mental resilience score was significantly lower than that of male’s. Correlation analysis showed that the scores of the Herth hope index, positive coping style, and family APGAR scale were positively correlated with the total scores of resilience and the scores of each dimension (all P<0.01). Multiple linear regression analysis showed that gender, the scores of Herth hope index, positive coping mode, family APGAR scale were main influencing factors of resilience ( P<0.05). Conclusion:Female patients with extracranial AVM need more attention to their psychological problems and psychological reactions. Herth hope, positive coping mode, family-centered care are the protective factors of resilience of patients with extracranial AVM.

Ischemic stroke is a common neurological disorder that can lead to neuronal death and neurological dysfunction. Microglia is the main immune cells in the central nervous system, involved in post-stroke inflammation and tissue repair. Triggering receptor expressed on myeloid cells 2 (TREM2), a receptor expressed on the surface of microglia, plays a multifaceted role in neuronal survival and nerve repair after ischemic stroke, including promoting the phagocytosis of microglia, inhibiting excessive inflammatory response, maintaining the proliferation and survival of microglia, protecting neurons from damage, and promoting the recovery of nerve function. Therefore, elucidating the immunoregulatory mechanism of TREM2 on microglia after cerebral ischemia is of great significance for exploring new therapeutic directions for ischemic stroke.

As the window of the hospital,the emergency department's medical quality determines the medical quality of the entire hospital.Emergency medical safety is the key to hospital construction.However,due to problems such as staffing and medical technology in the department of emergency of Chinese Medicine Hospitals,the development of medical quality is highly unbalanced.Aiming at the medical safety problems in the department of emergency of Chinese Medicine Hospitals in our country,the department of emergency of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine analyzed the current situation at home and abroad,examined the causes of medical errors,and put forward suggestions for the reform of medical safety in the department of emergency of Chinese Medicine Hospitals.It is recommended to effectively reduce medical errors through a series of reform measures such as hardware transformation and upgrading,standardization of standard procedures,establishing a sound communication mechanism,and creating a safety culture.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.
