Mediastinal and intrapulmonary types are the most common sites of occurrence, and thyroid BC is rare. This article aims to report a case of resection of thyroid BC with video-assistance technology to improve the understanding of the imaging, pathology and clinical aspects of this disease.

Objective:To identify the development trajectories of self-neglect behavior in older adults and explore the associated influencing factors.Methods:A fixed cohort was constructed based on the data from three surveys of Chinese longitudinal healthy longevity survey (CLHLS) from 2011 to 2018. A total of eight variables from 4 dimensions including living environment, lifestyle, social interaction, and health care were selected to evaluate self-neglect. Group-based trajectory model was used to identify the development trajectory of self-neglect behavior in the older adults, and polynomial Logistic regression model was used to explore its influencing factors by Stata 16.1.Results:Finally, 2 754 older adults aged 60 and above were included.The development trajectory of self-neglect behavior in older adults, based on the group-based trajectory model, can be classified into stable-low group ( n=268, 9.7%), descending-moderate group ( n=2 224, 80.8%), and decreasing-high group ( n=262, 9.5%). Polynomial Logistic regression showed that, compared with stable-low group, living in rural areas ( B=1.116, OR=3.053, 95% CI= 2.278-4.091) and higher activities of daily living scores( B=0.137, OR=1.147, 95% CI=1.046-1.258) were the risk factors of descending-moderate group. Education levels with 1-6 years( B=-0.398, OR=0.672, 95% CI=0.469-0.963), >6 years( B=-1.072, OR=0.342, 95% CI=0.229-0.513), being married( B=-0.476, OR=0.621, 95% CI=0.444-0.870), self-reported good health( B=-0.808, OR=0.446, 95% CI= 0.213-0.932), improved health status( B=-0.704, OR=0.495, 95% CI=0.320-0.766), self-reported average economic status( B=-1.065, OR=0.345, 95% CI=0.148-0.802), self-reported good economic status( B=-1.634, OR=0.195, 95% CI=0.082-0.467), and a higher cognition score( B=-0.142, OR=0.867, 95% CI=0.798-0.942) served as protective factors of descending-moderate group. In addition to the above factors, being in the age group of 75-89 years( B=0.481, OR=1.617, 95% CI=1.057-2.473) was a risk factor for decreasing-high group compared to stable-low group. Conclusions:Three types of self-neglect behavior trajectories among older adults were identified in this study, suggesting that physical health and economy are the influencing factors of the development trajectory of self-neglect of the elderly.

The subtype of lung cancer that presents as subsolid nodules on imaging exhibits unique biological behavior and favorable prognosis. Recently, the American Association for Thoracic Surgery (AATS) issued "The 2023 American Associationfor Thoracic Surgery (AATS) expert consensus document: Management of subsolid lung nodules". This consensus, based on the latest literature and current clinical experience, proposes updated strategies for managing subsolid nodules. It emphasizes the correlation between imaging findings and pathological classification, individualized follow-up and surgical management strategies for subsolid nodules, and multimodal treatment approaches for multiple subsolid pulmonary nodules.

Primary hyperthyroidism and thyroid cancer are usually considered as independent diseases,but recent studies suggest that these two diseases may share common pathogenic mechanisms.This article aims to emphasize the standardized diagnosis and treatment of primary hyperthyroidism patients with concomitant thyroid cancer.By comprehensively analyzing related domestic and foreign research,it provides useful reference and guidance for clinicians when dealing with patients with hyperthyroidism and concurrent thyroid cancer,to improve the level of diagnosis and treatment.

Parathyroid glands play an important role in calcium and phosphorus metabolism in human beings.The complete preservation of parathyroid glands during neck surgery is crucial in avoiding postoperative hypoparathyroidism and hypocalcemia.At present,most thyroid operations still rely on traditional visual identification or intraoperative freezing to identify parathyroid glands.The former depends on the experience of the surgeon,while the latter needs longer time and costs much.Recently,researchers have conducted relevant studies on intraoperative staining techniques and fluorescent-based imaging techniques that are helpful for the identification of parathyroid glands,such as methylene blue,carbon nanoparticles suspension,near-infrared autofluorescence,indocyanine green angiography,and laser speckle contrast imaging.The above-mentioned techniques all have significantly improved the identification and protection of parathyroid glands.This article reviews the progress in clinical research on intraoperative identification of parathyroid glands.

Objective To investigate the effect of Versican V0/V1 on biological behaviors of mouse dental papilla cells(mDPCs).Methods mDPCs were isolated from C57BL/6J mice at embryonic day 16.5(E16.5).A small interfering RNA(siRNA)constructed specifically for Versican V0/V1 was transfected into mDPCs.The silencing efficiency was verified by quantitative real-time fluorescence polymerase chain reaction(qRT-PCR)and immunofluorescence staining.The proliferation rate of mDPCs was determined using EdU assay;the migration ability of mDPCs was evaluated by scratch test and transwell assay.Alkaline phosphatase(ALP)staining and aliz-arin red staining were used to assess the mineralization capability of mDPCs.The molecules related to odontogenic differentiation and mineralization at mRNA levels were measured by qRT-PCR.Results After siRNA transfection,the mDPCs of si-Versican V0/V1 group showed weaker proliferation and migration abilities compared with si-NC group(P＜0.01).An enhanced ALP staining intensity,miner-alized nodule formation and up-regulations of the molecules related to odontogenic differentiation and mineralization at mRNA levels(P＜0.05)were observed in the mDPCs of si-Versican V0/V1 group.Conclusion Versican V0/V1 silencing inhibits the proliferation and migration of mDPCs,but enhances the abilities of odontogenic differentiation and mineralization.

Objective:To compare the results of invasive prenatal diagnosis and preimplantation genetic testing (PGT) and explore the underlying mechanism.Methods:Clinical data of pregnant women undergoing PGT and invasive prenatal diagnosis at the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to December 2022 were collected. The results of PGT and invasive prenatal diagnosis were compared, and the outcomes of pregnancies were followed up. This study has been approved by the Medical Ethics Committee of the the Sixth Affiliated Hospital of Sun Yat-sen University (No. 2022SLYEC-491).Results:A total of 172 couples were included in this study, and 26 non-targeted variants were discovered upon prenatal diagnosis, including 10 cases (38.5%) by chromosomal karyotyping, 15 (57.7%) by chromosomal microarray analysis (CMA), and 1 (3.8%) by whole exome sequencing. The 10 karyotypic anomalies had included 6 chromosomal polymorphisms, 2 chromosomal mosaicisms, 1 paternally derived translocation, and 1 missed maternal chromosomal inversion. CMA has identified 15 copy number variations (CNVs), which included 11 microdeletions and microduplications, 3 loss of heterozygosity, and 1 low-level mosaicism of paternal uniparental disomy. One CNV was classified as pathogenic, and another one was likely pathogenic, whilst the remaining 13 were classified as variants of uncertain significance. Therefore, 8.7% of CNVs was detected by invasive prenatal diagnosis after PGT. 92.3% (24/26) of the non-targeted variants have been due to technological limitations of next-generation sequencing (NGS).Conclusion:Invasive prenatal diagnosis after PGT can detect non-targeted variants, which may further reduce the incidence of birth defects.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

ObjectiveTo understand the health information needs of chronic disease inpatients and the current utilization of community health resources， and to analyze the influencing factors， so as to provide basis for personalized and high-quality health education for chronic disease inpatients and to guide them to make full use of community health resources. MethodsFrom November 2020 to February 2021， we conducted a face-to-face multi-center clinical epidemiological survey with paper questionnaire in three general hospitals of Shanghai. The study included 404 inpatients with diabetes， hypertension， coronary heart disease， chronic respiratory diseases， cancer and other chronic diseases. Results94.01% of the 404 respondents had different needs for disease or health related information， and there was no significant difference between patients of different ages， genders and educational backgrounds in their needs for health knowledge. Among these patients， only 39.11% of them participated in the establishment of a card for chronic disease management in the community or signed for a family doctor. The participation rate of male patients was lower than that of female patients （P<0.05）. ConclusionPatients with chronic diseases have a high demand for health related information， and we need to provide health information in multiple ways. We should increase investment in community health resources， improve service quality， and guide residents with chronic diseases to make full use of community health resources.

Along with the popularity of low-dose computed tomography lung cancer screening, an increasing number of early-stage lung cancers are detected. Radical lobectomy with systematic nodal dissection (SND) remains the standard-of-care for operable lung cancer patients. However, whether SND should be performed on non-metastatic lymph nodes remains controversy. Unnecessary lymph node dissection can increase the difficulty of surgery while also causing additional surgical damage. In addition, non-metastatic lymph nodes have been recently reported to play a key role in immunotherapy. How to reduce the surgical damage of mediastinal lymph node dissection for early-stage lung cancer patients is pivotal for modern concept of "minimally invasive surgery for lung cancer 3.0". The selective mediastinal lymph node dissection strategy aims to dissect lymph nodes with tumor metastasis while preserving normal mediastinal lymph nodes. Previous studies have shown that combination of specific tumor segment site, radiology and intraoperative frozen pathology characteristics can accurately predict the pattern of mediastinal lymph node metastasis. The personalized selective mediastinal lymph node dissection strategy formed from this has been successfully validated in a recent prospective clinical trial, providing an important basis for early-stage lung cancer patients to receive more personalized selective lymph node dissection with "precision surgery" strategies.
