Objective: To investigate the efficacy，safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes，operation time，intraoperative bleeding volume，incidence of lymph leakage，and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups，with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However，the indocyanine green group had shorter operation time，less intraoperative bleeding volume，and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection，but with fewer complications.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Objectives:To evaluate preoperative imaging anatomic characteristics and risk stratification in patients with pure aortic regurgitation(PAR)who underwent transcatheter aortic valve replacement(TAVR).Methods:A total of 156 consecutive patients with moderate or severe PAR who underwent TAVR from January 2018 to June 2023 in Fujian Provincial Hospital were enrolled.Pre-procedural aortic root computed tomography scans of the patients were analyzed to summarize anatomical risk points and typing.The clinical baseline data,perioperative data,and postoperative 12-month adverse events during follow-up of patients with different typing were compared.Results:The mean age of the 156 PAR patients treated with TAVR was(72.8±6.4)years,69.2%were male,and the STS score was(7.7±2.0)%.The proportion of PAR patients with simple,general and challenging lesions was 9.0%,37.8%and 53.2%,respectively.Results showed that enrolled patients with PAR treated with TAVR were at high risk of valve displacement(47.4%),and the risk of perivalvular leakage(26.9%),ascending aortic dilatation(26.9%),low coronary artery opening(37.2%)and transverse heart(23.7%)were also common.The risk of valve displacement and perivalvular leakage were significantly higher in PAR patients with challenging lesions.The risk of perioperative complications was significantly higher in patients with challenging and general lesions than in patients with simple lesions,and the most common complications were new left bundle branch block and pacemaker implantation.The 12-month adverse event rates after TAVR in PAR patients with simple,general,and challenge lesions were 0%,15.3%,and 32.5%,respectively,and the difference was statistically significant(P=0.004).Multivariate logistic regression analysis showed that PAR patients with challenging lesions had a significantly higher risk of multiple endpoint events 12 months after surgery than those with non-challenging lesions(OR=3.38,95%CI:1.48-8.38,P=0.006).Conclusions:Careful assessment of anatomic risk typing by preoperative imaging in PAR patients undergoing TAVR is important for risk stratification of perioperative complications as well as adverse events during follow-up.

Background and purpose:As one of the first-line treatment methods for differentiated thyroid cancer(DTC),131I treatment is an important therapeutic approach for most patients with medium-high recurrence risk DTC after total or near-total thyroidectomy.Risk stratification and real-time dynamic assessment before 131I treatment after surgery are important steps in deciding on 131I treatment,enabling individualized treatment.This retrospective study aimed to explore the role of diagnostic whole body scan(DxWBS)in the decision-making of treatment for DTC after surgery and before 131I therapy.Methods:DTC patients who underwent pre-ablation evaluation were included.Patients were divided into low,medium and high sTg groups based on their pre-131I treatment stimulated thyroglobulin(sTg)levels(＜1 ng/mL,1 ng/mL≤sTg＜10 ng/mL,sTg≥10 ng/mL).The concordance rates of DxWBS and post treatment whole body scan(RxWBS)in each patient of the whole cohort were compared.The lesion detection rate between DxWBS and RxWBS in different sTg level groups was also explored.The"thyroid stunning effect"by DxWBS was evaluated by RxWBS.Through these analyses,the role of DxWBS in 131I treatment decision-making and its predicting treatment objectives were assessed.This study was approved by the Ethics Committee of Peking Union Medical College Hospital,Peking Union Medical College,Chinese Academy of Medical Sciences(ethics number:JS-2151).Results:A total of 91 patients were included.The low,medium and high sTg groups accounted for 15.4%(14/91),34.1%(31/91)and 50.5%(46/91)of the patients,respectively.Comparison of DxWBS and RxWBS results in the same patients in each sTg group showed no evidence of a stunning effect on 131I treatment.The overall concordance rate between DxWBS and RxWBS was 89.0%(81/91);In different sTg level groups was 100.0%(14/14),90.3%(28/31),84.8%(39/46)respectively.Taking sTg levels into consideration,DxWBS accurately predicted the need for total thyroidectomy,with a 100%(20/20)agreement with RxWBS.Among the 71 patients who received adjuvant therapy and/or remnant ablation due to suspected elevated Tg or high recurrence risk stratification or the iodine-avid metastatic lesions identified by DxWBS,87.5%(63/71)showed only residual thyroid tissue by DxWBS;Through the purpose verification by RxWBS and single photon emission computed tomography(SPECT)/CT,only 12.7%(9/71)of cases were verified as adjuvant or tumoricidal treatment due to iodine-avid cervical lymph node and/or lung metastasis identified by RxWBS,87.3%(62/71)were residual thyroid ablation.In the medium and high sTg group,the overall detection rate of functional cervical lymph node metastasis by DxWBS and RxWBS was 5.5%(5/91).For the detection of functional lung metastases,the overall detection rate of DxWBS was slightly lower than that of RxWBS(3.3%vs 5.5%).This indicates that DxWBS can be used to accurately pre-judge the purposes of 131I treatment,particularly for thyroid ablation and adjuvant therapy.Conclusion:DxWBS did not induce"thyroid stunning"effect.Integrating DxWBS as a theranostic tool into the real-time decision-making and evaluation system of 131I treatment,as well as with sTg and other biochemical indicators,may help to bridge the limitations of static evaluations based on pathology and clinical data,and provides a clear understanding and more precise objectives of 131I treatment.

Objective To investigate the efficacy,safety and feasibility of laparoscopic lymph node dissection guided by indocyanine green(ICG)fluorescence imaging.Methods A total of 30 patients with muscle-invasive bladder cancer(MIBC,T2/T3NxM0)who were admitled to the Cangzhou People's Hospital during Mar.2018 and Jun.2022 were included.The lymph nodes were cleared with ICG fluorescence imaging first,and then the remaining lymph nodes were cleared according to the standard pelvic lymph node range.The lymph node positive rate of ICG fluorescence imaging guided laparoscopic lymph node precise dissection and standard pelvic lymph node dissection was analyzed by self-comparison.Results ICG fluorescence imaging guided laparoscopic lymph node precise dissection needed shorter operation time than standard pelvic lymph node dissection[(21.80±6.80)min vs.(47.70±10.73)min,P＜0.05].There was no significant difference in the lymph node positive rate between the two approaches[(11.34±9.06)％vs.(12.36±9.43)％,P＞0.05],but the former approach caused less damage on blood vessels and nerves.Conclusion Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable efficacy to standard pelvic lymph node dissection,which can reduce ineffective lymph node dissection,shorten the operation time,and reduce the risk of complications.

BACKGROUND:Osteoarthritis is one of the most common senile chronic degenerative diseases in China.Due to its complex pathogenesis and cellular molecular communication pathways,there is currently no effective method to slow down the progression of osteoarthritis.Studies have found that transforming growth factor-β is one of the key factors in the maintenance and regulation of joint stability and plays a significant role in the formation of early joints,as well as the development of bone and cartilage,and the remodeling of joints at various stages. OBJECTIVE:To review the regulatory role of the transforming growth factor-β subfamily in the occurrence and development of osteoarthritis,both domestically and internationally in recent years,to analyze the impacts it has at different stages of osteoarthritis,and to explore the potential application prospects of transforming growth factor-β in the clinical treatment of osteoarthritis,with a view to informing clinical treatment protocols.. METHODS:The relevant articles were searched by computer from CNKI Database and PubMed Database.The search terms were"osteoarthritis,transforming growth factor,signaling pathway,bone remodeling,cartilage degeneration,angiogenesis,treatment"in Chinese and English,respectively.Finally,57 articles were included for review. RESULTS AND CONCLUSION:The pathogenesis of osteoarthritis remains a subject of ongoing exploration with no unified consensus.Numerous studies highlight the close correlation between osteoarthritis and cytokines,focusing on the transforming growth factor-β superfamily as a pivotal mechanism and therapeutic breakthrough.Transforming growth factor-β plays a crucial role in early joint cartilage formation and maintenance,promoting cartilage repair.However,post-joint formation,its protective effect weakens,leading to potential destructive consequences.This dual regulatory role is a current clinical treatment focus,necessitating further research to delineate its application scope for standardized protocols.Highly active transforming growth factor-β participates in the regulation of bone cells,osteoblasts,and osteoclasts under mechanical stress,and intervenes in the subsequent remodeling of bone microstructure.Specific inhibitors present potential targeted therapeutics,yet their safety and efficacy in clinical settings require refinement.Vascular proliferation may serve as a potential disruptive pathway in transforming growth factor-β-mediated cartilage degeneration and subchondral bone remodeling.Abnormal communication pathways can further disrupt the homeostasis of the microenvironment of osteochondral units,thereby accelerating key pathological progressions of osteoarthritis.Research on transforming growth factor-β in osteoarthritic contexts is comprehensive,holding broad clinical application prospects.Drugs related to transforming growth factor-β are in clinical trial phases,but addressing potential impacts on other tissues and precise control of targeted delivery are critical concerns.As research advances,there is optimism for innovative breakthroughs in slowing the progression of osteoarthritis in the future.
