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.

The main pathological features of Parkinson disease(PD)include accumulation of α-synuclein and loss of dopaminergic neurons.PET imaging can be used to diagnose and monitor PD and explore its neural mechanisms through specific targeted imaging agents.The research progresses of PD related PET imaging agents were reviewed in this article.

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.

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.

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.

Objectives:To evaluate the learning curve of transcatheter aortic valve replacement(TAVR)in a single center by single operator using Venus A valve. Methods:A total of 150 patients with severe aortic stenosis who underwent TAVR using Venus A valve in Fujian Provincial Hospital from July 2018 to May 2022 were selected.According to the time order of TAVR,the 1st-50th patients were included in group A,the 51st-100th patients were included in group B and the 101st-150th patients were included in group C.The basic clinical data,perioperative parameters and postoperative follow-up data of the three groups were analyzed. Results:All high-risk patients with severe aortic stenosis had an average STS score(7.9±1.5)and were treated with Venus A valve.The total operation time of group A,group B and group C was(226.2±86.3)min,(115.2±47.1)min,(108.2±38.1)min;the peripheral path operation time was(45±10)min,(20±7)min,(18±6)min;the valve release time was(13.0±2.3)min,(5.0±2.1)min,(3.0±1.7)min;the X-ray fluoroscopy time was(24±8)min,(11±5)min,(10±3)min;the radiation dose was(1 266±227)mGy,(532±132)mGy,(519±108)mGy;and the total incidence of perioperative adverse events was 46%,18%,16%,respectively.The differences were statistically significant(all P<0.05).The total incidence of adverse events during follow-up within 6 months for patients in group A,group B,and group C were 6%,2%,and 0%(P>0.05).With the increase of TAVR cases,the correlation curve of each time node of TAVR and radiation dose tended to be stable after the 50th-60th cases. Conclusions:With the increase of procedural experience,the total operation time,operative time nodes,radiation dose and perioperative adverse events of TAVR with Venus A valve decreases gradually,and the operator usually needs 50-60 cases to cross the TAVR learning curve.

Glioma is the most common primary central nervous system tumor,mainly derived from glial cells,with strong invasiveness,easy recurrence,and poor prognosis.Glioblastoma is a high-grade glioma with the highest degree of malignancy.The clinical treatment method is mainly surgical resection,supplemented by compre-hensive treatment such as radiotherapy,chemotherapy,and electric field therapy,but the treatment effect is not satisfactory.In recent years,with the rapid development of the field of tumor immunotherapy,CD73 is a novel immune checkpoint related to adenosine metabolism,which can promote tumor progression by inhibiting anti-tumor immune responses and promoting angiogenesis.This article systematically reviews the mechanism of action of CD73 and discusses its biological role and application in glioma,aiming to provide potential treatment options for glioma patients.
