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 investigate the expression levels of miRNA-21 (miR-21) and miRNA-330 (miR-330) in serum exosomes of non-small cell lung cancer (NSCLC) patients with brain metastases, and the correlation of the two with the prognosis of patients.Methods:A prospective cohort study was conducted. A total of 125 NSCLC patients who were admitted to the Affiliated People's Hospital of Shandong First Medical University from March 2021 to September 2022 were prospectively selected, and the brain metastasis was determined by CT, contrast-enhanced magnetic resonance imaging of the head, or surgical pathology. The NSCLC patients were divided into the metastatic group (58 cases) and the non-metastatic group (67 cases) according to whether they had brain metastases, and 50 patients with benign lung diseases and 50 healthy subjects who underwent physical examination in the same period were selected as benign group and healthy control group respectively. Serum samples were collected from all subjects (including patients' pre-treatment samples), the exosomes were extracted, and real-time fluorescence quantitative polymerase chain reaction was used to determine the relative expression of miR-21 and miR-330 in exosomes at the transcriptional level, and electrochemiluminescence immunoassay was used to detect the levels of serum tumor markers [neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA)]. The levels of miR-21 and miR-330 in serum exosomes and serum tumor markers in the 4 groups were compared, and the correlation between miR-21 and miR-330 in serum exosomes of NSCLC patients with brain metastases before treatment and the correlation between miR-21, miR-330 and serum tumor markers were analyzed by Pearson method. Using brain metastases identified by CT, contrast-enhanced magnetic resonance imaging of the head or surgical pathology as the gold standard, the receiver operating characteristic (ROC) curves were drawn to determine the occurrence of brain metastases in NSCLC patients based on the levels of miR-21, miR-330 and their combination in the serum exosomes before treatment. NSCLC patients were divided into the poor prognosis group and the good prognosis group according to whether or not they died of tumor during the follow-up period, and the clinical characteristics and levels of miR-21 and miR-330 in serum exosomes before treatment were compared between the two groups. The independent influencing factors of death due to tumor in NSCLC patients were analyzed by multivariate logistic regression.Results:Among 125 NSCLC patients, 68 (54.4%) were male and 57 (45.6%) were female; the age was (63±5) years old, ranging from 49 to 82 years old; 89 patients (71.2%) were adenocarcinoma and 36 patients (28.8%) were squamous cell carcinoma. The transcriptional level relative expression of miR-21 in serum exosomes of healthy control group, benign group, non-metastatic group and metastatic group increased sequentially, the transcriptional level relative expression of miR-330 decreased sequentially, the protein concentrations of NSE, CEA and SCCA increased sequentially, and the differences between each two groups were statistically significant (all P<0.001). Pearson correlation analysis showed that in the serum exosomes of NSCLC patients with brain metastases before treatment, miR-21 was positively correlated with serum NSE, CEA and SCCA levels ( r values were 0.641, 0.785 and 0.612, respectively; P values were 0.015, 0.011 and 0.019, respectively), miR-330 in the serum exosomes before treatment was negatively correlated with serum NSE, CEA, and SCCA levels ( r values were -0.612, -0.689 and -0.587, respectively; P values were 0.016, 0.021 and 0.013, respectively), and miR-21 was positively correlated with miR-330 in the serum exosomes before treatment ( r = -0.529, P = 0.023). ROC curve analysis showed that the area under the curve of miR-21, miR-330 and their combination in serum exosomes before treatment for determining the occurrence of brain metastases in NSCLC patients were 0.861 (95% CI: 0.792-0.931), 0.894 (95% CI: 0.840-0.947) and 0.906 (95% CI: 0.849-0.963), and the differences were statistically significant (all P < 0.001). The optimal cut-off value of miR-21 relative expression was 1.625, and the corresponding sensitivity and specificity were 77.4% and 71.5%, respectively; the optimal cut-off value of miR-330 was 0.611, and the corresponding sensitivity and specificity were 81.1% and 74.9%, respectively; the sensitivity and specificity when the two were combined to reach the optimal cut-off value were 84.5% and 73.8%, respectively. NSCLC patients were followed up for a median time of 19 months (95% CI: 17-21 months), and 23 cases (18.4%) died due to the tumor during the follow-up period. The proportions of patients with age ≥60 years old, clinical stage Ⅲ-Ⅳ and brain metastases and the relative expression of miR-21 in serum exosomes before treatment in the poor prognosis group were higher than those in the good prognosis group, the relative expression of miR-330 in the serum exosomes before treatment was lower than that in the good prognosis group, and the differences were all statistically significant (all P < 0.05). Multivariate logistic regression analysis showed that the high age (≥60 years old vs. <60 years old, OR = 3.750, 95% CI: 1.191-11.806, P = 0.024), late clinical stage (stage Ⅲ-Ⅳ vs. stage Ⅰ-Ⅱ, OR = 4.667, 95% CI: 1.303-16.716, P = 0.018), brain metastasis (with metastasis vs. non-metastasis, OR = 2.573, 95% CI: 1.008-6.611, P = 0.049), and elevated relative expression of miR-21 in serum exosomes before treatment ( OR = 2.585, 95% CI: 1.198-6.152, P = 0.008) were the independent risk factors for death due to tumor in NSCLC patients, and elevated relative expression of miR-330 in serum exosomes before treatment was an independent protective factor for death due to tumor ( OR = 0.821, 95% CI: 0.715-0.954, P < 0.001). Conclusions:miR-21 level is high and miR-330 level is low in serum exosomes of NSCLC patients with brain metastases before treatment, and there is a negative correlation between them, and they are closely related to various serum tumor markers of NSCLC patients with brain metastases and NSCLC patients' prognosis; the combination of the two may predict the occurrence status of brain metastases in NSCLC.

Objective:To investigate the efficacy and safety of neoadjuvant therapy with trastuzumab and pertuzumab combined with taxane and platinum drugs (TCbHP) regimen for human epidermal growth factor receptor 2 (HER2)-positive breast cancer.Methods:A retrospective case series study was conducted. The clinical data of HER2-positive breast cancer patients who received neoadjuvant therapy with 21-day TCbHP regimen and completed subsequent surgery in 11 tertiary-level hospitals in Hebei Province from June 2019 to December 2021 were retrospectively analyzed, and the total pathological complete remission (tpCR) rate, the incidence of grade ≥3 adverse events, and the completion rate of the established regimen were statistically analyzed.Results:A total of 78 female patients were included and the median age [ M ( Q1, Q3)] was 54.0 years (48.5 years, 57.5 years). The tpCR rate was 64.1% (50/78). Subgroup analysis showed that the tpCR rate in the HER2 immunohistochemistry (IHC)+++ group was higher than that in the HER2 IHC++ and fluorescence in situ hybridization-positive group [68.6% (48/70) vs. 25.0% (2/8)], and the difference was statistically significant ( χ2 = 4.18, P = 0.041); the tpCR rate in the hormone-receptor negative group was higher than that in the hormone-receptor positive group [81.8% (27/33) vs. 51.1% (23/45)], and the difference was statistically significant ( χ2 = 7.80, P = 0.005); the tpCR rate in the albumin-bound paclitaxel group was higher than that in the docetaxel group [72.3% (34/47) vs. 48.3% (14/29)], and the difference was statistically significant ( χ2 = 4.46, P = 0.035). The incidence of ≥ grade 3 adverse reactions was 12.8% (10/78) in 78 patients, and the completion rate of the established regimen was 92.3% (72/78). Conclusions:Neoadjuvant therapy with TCbHP regimen for HER2-positive breast cancer shows a definite efficacy, good safety and tolerance.

Objective To investigate the relationship between the therapeutic effect of anti-vascular endothelial growth factor(VEGF)and cytokines in aqueous humor in patients with diabetic retinopathy(DR).Methods From July 2023 to December 2023,50 DR patients(56 eyes)who were treated with anti-VEGF drugs in the Department of Ophthal-mology,the Third Affiliated Hospital of Xinxiang Medical University were included in this study.The patients were divided into the diabetic macular edema(DME)group(30 patients,36 eyes)and the proliferative DR(PDR)group(20 patients,20 eyes).Patients in the DME group received an intravitreal injection of aflibercept once a month for three consecutive times,with aqueous humor extracted before each injection.Patients in the PDR group received an intravitreal injection of aflibercept one week before vitrectomy,with aqueous humor extracted before injection and during vitrectomy,respective-ly.The concentrations of vascular endothelial growth factor A(VEGF-A),placental growth factor(PLGF),interleukin(IL)-1β,IL-23,IL-17A,and tumor necrosis factor-α(TNF-α)in the aqueous humor were detected using the Luminex as-say.Before injection therapy,all patients underwent best corrected visual acuity(BCVA)and central macular thickness(CMT)examinations,and their correlations with cytokine concentrations in DR patients before injection therapy were ana-lyzed.Results Compared to before injection therapy,the concentrations of VEGF-A,PLGF,and IL-23 in the aqueous humor of patients in the DME group decreased significantly after treatment(all P＜0.05);additionally,the CMT de-creased,and the BCVA increased(both P＜0.05).After injection therapy,the concentrations of VEGF,PLGF,IL-1β,IL-23,IL-17A,and TNF-α in the aqueous humor of patients in the PDR group significantly decreased compared to before injec-tion therapy(all P＜0.05).Before injection therapy,the levels of VEGF-A,PLGF,and IL-23 in the aqueous humor of pa-tients in the DME group were higher than those in the PDR group,and the differences were statistically significant(all P＜0.05).The correlation analysis results showed that before injection therapy,VEGF was negatively correlated with BCVA(r=-0.767,P=0.004)and was positively correlated with CMT(r=0.662,P=0.019)and IL-23(r=0.765,P=0.004)in the DME group.There was no correlation between the cytokines in the aqueous humor of patients in the PDR group be-fore injection therapy(all P＞0.05).Conclusion Changes in the concentration of VEGF-A,PLGF,and IL-23 are closely related to the occurrence and development of DR.Anti-VEGF treatment can improve BCVA and decrease CMT in DME pa-tients.The expression level of IL-23 in aqueous humor can serve as a predictive factor for the anti-VEGF efficacy in DR pa-tients,providing new targets for early diagnosis and treatment of DR.
