Retinal vein occlusion(RVO)is the second most common blinding retinal vascular disease, and its secondary macular edema(ME)is an important cause of visual function impairment in patients. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs serves as the first-line treatment, yet it is confronted with such issues as the need for repeated injections and non-response in some patients. Imaging and laboratory biomarkers play a crucial role in the early accurate diagnosis, prediction of disease progression, and evaluation of visual prognosis of RVO-ME. This study systematically reviews the research progress of imaging and laboratory biomarkers related to the prognosis of RVO-ME after anti-VEGF treatment in recent years, covering imaging biomarkers like central retinal thickness and ellipsoid zone integrity, as well as laboratory biomarkers such as serum APLN and aqueous humor IL-6. It summarizes the associations between different biomarkers and the prognosis of anti-VEGF therapy, aiming to provide a basis for the early accurate assessment and optimization of individualized treatment for RVO-ME patients, which holds significant clinical reference value.

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.

OBJECTIVE: To investigate the effect of autologous osteochondral tissue and periosteum transplantation on tendon-bone healing of rotator cuff in rabbits. METHODS: Twenty-four male New Zealand white rabbits were randomly divided into autologous osteochondral tissue and periosteum transplantation group (experimental group, n=12) and simple suture group (control group, n=12). Both groups were subjected to acute supraspinatus tendon injury and repaired with corresponding techniques. At 4, 8, and 12 weeks after operation, 4 specimens from each group were taken from the right shoulder joint for histological examination (HE staining, Masson staining, and Safranin O-fast green staining), and the left shoulder was subjected to biomechanical tests (maximum tensile load and stiffness). RESULTS: Both groups of animals survived until the completion of the experiment after operation. At 4 weeks after operation, both groups showed less collagen fibers and disorder at the tendon-bone junction. At 8 weeks, both groups showed reduced inflammation at the tendon-bone junction, with more organized and denser collagen fibers and chondrocytes. The experimental group showed better results than the control group. At 12 weeks, the experimental group showed typical tendon-bone transition structure, with increased generation of collagen fibers and chondrocytes, and the larger cartilage staining area. Both groups showed an increase in maximum tensile load and stiffness over time ( P<0.05). The stiffness at 4 weeks and the maximum tensile load at 4, 8, and 12 weeks in the experimental group were superior to control group, and the differences were significant ( P<0.05). There was no significant difference in stiffness at 8, 12 weeks between the two groups ( P>0.05). CONCLUSION Autologous osteochondral tissue and periosteum transplantation can effectively promote the fiber and cartilage regeneration at the tendon-bone junction of rotator cuff and improve the biomechanical effect of shoulder joint in rabbits.

OBJECTIVE To comprehensively evaluate the quality of adverse drug reaction （ADR） reports in clinical departments or ward （hereinafter referred to as “department”） based on game theory combinatorial weighting-technique for order preference by similarity to ideal solution （TOPSIS）-rank-sum ratio （RSR） method， providing a reference for the further standardization of ADR reporting. METHODS Based on relevant documents and scoring criteria， the ADR report quality evaluation standards previously developed by our team were modified. Using game theory principles， the fusion of subjective and objective weights for each indicator was determined. A game theory combinatorial weighting-TOPSIS-RSR model was developed to evaluate and categorize the quality of raw ADR reports submitted by departments to the pharmacy department at Bozhou Hospital of Anhui Medical University. RESULTS A total of 222 ADR reports from 23 departments were included. The game theory combinatorial weighting method identifies weak points in management， such as ADR symptoms and signs， the description of underlying diseases， timing of ADR， by optimizing the weightings of the indicators. The TOPSIS-RSR method calculates that the mean relative closeness of the departments was 0.401 7， indicating that the overall report quality ranged from moderate to substandard. 20095） Three departments， including neurosurgery， demonstrated medium reporting quality [estinate closeness （Ĉ）i ≥0.506]， while two departments， such as the respiratory department，were rated as unqualified （Ĉi＜0.278）. The remaining departments were all deemed qualified （0.278≤ Ĉi＜0.506）. CONCLUSIONS The developed game theory combinatorial weighting-TOPSIS-RSR method provides an effective approach for the quality evaluation of ADR reports， which not only balances subjective and objective weights but also facilitates comparisons among different departments. There is still room for improvement in the ADR report quality at the hospital.

The primary intravenous anesthetics employed in clinical practice encompass dexmedetomidine (Dex), propofol, ketamine, etomidate, midazolam, and remimazolam. Apart from their established sedative, analgesic, and anxiolytic properties, an increasing body of research has uncovered neuroprotective effects of intravenous anesthetics in various animal and cellular models, as well as in clinical studies. However, there also exists conflicting evidence pointing to the potential neurotoxic effects of these intravenous anesthetics. The role of intravenous anesthetics for neuro on both sides of protection or toxicity has been rarely summarized. Considering the mentioned above, this work aims to offer a comprehensive understanding of the underlying mechanisms involved both in the central nerve system (CNS) and the peripheral nerve system (PNS) and provide valuable insights into the potential safety and risk associated with the clinical use of intravenous anesthetics.

Increasing evidence showed that histone deacetylase 6 (HDAC6) dysfunction is directly associated with the onset and progression of various diseases, especially cancers, making the development of HDAC6-targeted anti-tumor agents a research hotspot. In this study, artificial intelligence (AI) technology and molecular simulation strategies were fully integrated to construct an efficient and precise drug screening pipeline, which combined Voting strategy based on compound-protein interaction (CPI) prediction models, cascade molecular docking, and molecular dynamic (MD) simulations. The biological potential of the screened compounds was further evaluated through enzymatic and cellular activity assays. Among the identified compounds, Cmpd.18 exhibited more potent HDAC6 enzyme inhibitory activity (IC₅₀ = 5.41 nM) than that of tubastatin A (TubA) (IC₅₀ = 15.11 nM), along with a favorable subtype selectivity profile (selectivity index ≈ 117.23 for HDAC1), which was further verified by the Western blot analysis. Additionally, Cmpd.18 induced G2/M phase arrest and promoted apoptosis in HCT-116 cells, exerting desirable antiproliferative activity (IC₅₀ = 2.59 μM). Furthermore, based on long-term MD simulation trajectory, the key residues facilitating Cmpd.18's binding were identified by decomposition free energy analysis, thereby elucidating its binding mechanism. Moreover, the representative conformation analysis also indicated that Cmpd.18 could stably bind to the active pocket in an effective conformation, thus demonstrating the potential for in-depth research of the 2-(2-phenoxyethyl)pyridazin-3(2H)-one scaffold.

Prostate cancer (PCa) is the most common urological malignancy in men worldwide, and its incidence is increasing annually. Radiotherapy is one of the main treatment methods for PCa. However, some patients still have recurrence, local progression, and even distant metastasis after receiving radical radiotherapy. As an emerging tumor treatment strategy, immunotherapy has made great progress in the treatment of various solid tumors. Owing to the inherent immune escape mechanism of PCa, the efficacy of immunotherapy is unsatisfactory. Therefore, new combined strategies must be explored to improve the efficacy of immunotherapy for PCa. With the in-depth study of the tumor immune microenvironment, the immunomodulatory effect of radiotherapy has gradually attracted attention. Researchers found that the immunomodulatory effect of radiotherapy depends on the dose. Low-dose radiotherapy can enhance tumor immunogenicity by remodeling the tumor microenvironment, whereas high-dose radiotherapy can further activate the innate immune signaling pathway by directly inducing the immunogenic necrosis of tumor cells. Therefore, the synergistic strategy of radiotherapy and immunotherapy has become a research hotspot. This work aims to review the regulatory effect of radiotherapy on PCa antitumor immunity, clarify the latest progress and potential clinical value of radiotherapy combined with immunotherapy, and provide a theoretical basis and new research directions for optimizing the combination immunotherapy strategies for prostate cancer.

Objective To explore the difference of transfer RNA-derived small RNA(tsRNA)expression profile before and after acute myocardial infarction(AMI)and the diagnostic value of tsRNA for AMI.Methods Age-and weight-matched male C57 mice(8-10 weeks)were randomly divided into MI group and Sham group,with 4 in each group.AMI model was surgically induced in mice in MI group.After 24 h of modeling,RNA was extracted from left ventricular myocardial tissue.After removing modifications,total RNA of each sample was sequentially ligated to 3'and 5'small RNA adapters.Subsequently,reverse transcription PCR was performed.cDNA was then synthesized and amplified.The amplified products corresponding to the size of 15-40 nt RNA were screened to construct a library for sequencing.The sequencing results were compared with the mature tRNA and tRNA precursor sequences in GtRNAdb database.Differentially expressed tsRNA profiles before and after AMI were obtained.The alterations of the cleaved patterns of tRNA corresponding to the same codon before and after AMI were analyzed.According to the profile of differentially expressed tsRNA before and after AMI,tsRNA only abundantly expressed in MI group were selected and verified in myocardial tissue and plasma of mice to explore the potential of these tsRNAs as diagnostic markers of AMI.Results tsRNA profile showed good repeatability within the same group and great distinctiveness between the different groups.After AMI occurred,the cleaved patterns of a variety of tRNAs changed,including tRNA Asn-GTT,Glu-TTC,Gly-ACC,Gly-GCC,His-GTG,Ile-AAT,Ile-GAT,Pro-TGG,Ser-AGA,and Trp-CCA.Compared with the Sham group,268 tsRNAs significantly up-regulated and 1 228 tsRNAs down-regulated in MI group,and 64 tsRNAs were uniquely expressed in MI group.tRF-Gly-CCC-2-31,tiRNA-Val-CAC-1-32,tiRNA-Val-AAC-2-32,tiRNA-Glu-TTC-2-32,and tiRNA-Lys-TTT-1-34 were specifically expressed in cardiac tissue on the 1st day post AMI.Among them,tiRNA-Val-AAC-2-32 and tiRNA-Lys-TTT-1-34 showed specifically abundant levels in plasma from MI group and dynamically changed with AMI duration.Conclusions The expression profile of tsRNA is significantly different before and after AMI.tiRNA-Val-AAC-2-32 and tiRNA-Lys-TTT-1-34 are uniquely highly expressed in myocardial tissue and plasma from AMI mice,and might have the potential as diagnostic markers of AMI.

OBJECTIVE To test whether there are some differences among chronic rhinitis,chronic rhinosinusitis patients with nasal polyps(CRSsNP)and without nasal polyps(CRSsNP)in symptom severity,health-related quality-of-life impairment,and objective inflammatory factors.METHODS A total of 154 consecutive patients who had been treated at the Otolaryngology Department of Beijing Tongren Hospital from January 2017 to December 2018 were recruited in this study.The patients aged 18-70 years,with 106 males and 48 females.All patients performed endoscopic examination,nasal exhaled nitric oxide(nNO),skin prick test(SPT),sinus CT scan,complete blood count,and fulfilled the visual analogue scale(VAS)self-assessment of nasal symptoms and the SNOT-22 questionnaire under the guidance of the physician.According to the inclusion criteria,A total of 43 patients with CR,58 patients with CRSsNP and 53 patients with CRSwNP were enrolled in our study.RESULTS The total SNOT-22 score in CRSsNP group was significantly lower than that in CR and CRSwNP groups(30.0±19.4 vs.41.1±21.9,30.0±19.4 vs.40.9±18.7,P<0.05),and there was no significant difference between CR group and CRSwNP group.The average scores of nasal symptoms and extranasal symptoms in CRSwNP group were the highest;the scores in CRSsNP group were lower.The impact of CR patients on sleep damage was significantly higher than that in CRSsNP patients(9.9±6.2 vs.5.1±5.3,P<0.05),and there was no significant difference between CR group and CRSwNP group(9.9±6.2 vs.7.1±5.7,P>0.05).When patients suffered with positive SPT,there was no statistical difference in symptom scores and SNOT-22 scores between CR,CRSsNP,and CRSwNP;but with negative SPT,there was a significant statistical difference in both symptom scores and SNOT-22 scores among the three groups.CONCLUSION CR,CRSsNP and CRSwNP have a significant impact on quality of life,respectively.In terms of symptom scores and quality of life scores,the CR group and CRSwNP group are similar and the scores are higher than that of the CRSsNP group.However,the objective inflammation factors are not consistent with the subjective symptom scores and quality of life scores.

OBJECTIVE To predict biomarkers of type 2 inflammation in chronic rhinosinusitis with nasal polyps(CRSwNP)by employing peripheral blood indicators.METHODS CRSwNP patients admitted to the Rhinology Department of Beijing Tongren Hospital from June 2020 to May 2022 were enrolled and their basic clinical data were collected.The blood percentage of eosinophils(Eos%),Eos count,periostin and total IgE,as well as mucosal interleukin-5(IL-5)and Staphylococcus aureus enterotoxin-immunoglobulin E(SE-IgE)were tested.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of each blood indicator for positive mucosal expression of IL-5/SE-IgE.The logistic regression was employed to screen multiple blood indicators with predictive value for positive mucosal expression of IL-5/SE-IgE in order to construct a nomogram model.RESULTS The proportion of asthma,blood Eos%,periostin and total IgE in CRSwNP patients showed statistical differences between IL-5/SE-IgE positive and negative subgroups.ROC univariate analysis demonstrated that blood Eos%,Eos count,periostin and total IgE could predict mucosal IL-5 positivity with AUC ranging from 0.655 to 0.784,and mucosal SE-IgE positivity with AUC ranging from 0.721-0.802.The logistic regression confirmed that blood Eos%and total IgE,as well as blood periostin and total IgE were independent predictors for mucosal IL-5 and SE-IgE positivity,respectively.The nomogram models were constructed for predicting IL-5/SE-IgE positivity in CRSwNP mucosa,with consistency incides(C-index)of 0.804 and 0.81,indicating good predictive accuracy.CONCLUSION The nomograms constructed based on blood Eos%and total IgE,as well as blood periostin and total IgE,could have good predictive value for the positive mucosal expression of IL-5 and SE-IgE in the CRSwNP,which help to predict the severity of endotype and phenotype of CRSwNP.
