Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

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.

Sophorae Flavescentis Radix is one of the commonly used traditional Chinese medicine in China, and a large amount of pharmaceutical residue generated during its processing and production is discarded as waste, which not only wastes resources but also pollutes the environment. Therefore, elucidating the chemical composition of the residue of Sophorae Flavescentis Radix and the differences between the residue and Sophorae Flavescentis Radix itself is of great significance for the comprehensive utilization of the residue. This study, based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) technology combined with multivariate statistical methods, provides a thorough characterization, identification, and differential analysis of the overall components of Sophorae Flavescentis Radix and its residue. Firstly, 61 compounds in Sophorae Flavescentis Radix were rapidly identified based on their precise molecular weight, fragment ions, and compound abundance, using a self-constructed compound database. Among them, 41 compounds were found in the residue, mainly alkaloids and flavonoids. Secondly, through principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA), 15 key compounds differentiating Sophorae Flavescentis Radix from its residue were identified. These included highly polar alkaloids, such as oxymatrine and oxysophocarpine, which showed significantly reduced content in the residue, and less polar flavonoids, such as kurarinone and kuraridin, which were more abundant in the residue. In summary, this paper clarifies the overall composition, structure, and content differences between Sophorae Flavescentis Radix and its residue, suggesting that the residue of Sophorae Flavescentis Radix can be used as a raw material for the extraction of its high-activity components, with promising potential for development and application in cosmetics and daily care. This research provides a scientific basis for the future comprehensive utilization of Sophorae Flavescentis Radix and its residue.

OBJECTIVES: To investigate the medium- and long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation for treatment of iliac vein stenosis with lower extremity deep venous thrombosis (LEDVT). METHODS: Clinical and follow-up data of 125 patients with iliac vein stenosis and LEDVT who underwent PMT and stent implantation at five hospitals in northern Zhejiang province from January 2017 to June 2021 were collected. The thrombus clearance rate, thrombus recurrence rate, patency rate of iliac vein stents and post-thrombotic syndrome (PTS) occurrence rate were documented, and safety indicators such as bleeding, death, pulmonary embolism, stent fracture and displacement were assessed. RESULTS: Among 125 patients, for clearance of limb thrombosis, there were 8 cases of grade I (6.4%), 10 cases of grade II (8.0%), and 107 cases of grade III (85.6%). Patients were followed up for a median period of 74 months. According to the Villalta score, the recurrence rates of limb thrombosis at 12, 24 and 36 months were 8.48%, 8.93% and 10.91%; the iliac vein patency rates were 91.52%, 91.07%, and 89.09%; and the incidences of PTS were 5.08%, 5.36% and 6.36%, respectively. There were no major adverse events such as death, massive pulmonary embolism or severe hepatic and renal insufficiency, and no readmission intervention events due to stent fracture or other incidence were found. CONCLUSIONS PMT combined with iliac vein stent implantation is effective for patients with iliac vein stenosis complicated by LEDVT with good medium- and long-term efficacy and safety, which is worthy of clinical application.

OBJECTIVE: To investigate the clinical features, treatment and prognosis of extranodal NK/T-cell lymphoma, nasal type (ENKTL) with skin lesions as initial symptom. METHODS: The clinical data of 11 ENKTL patients with skin lesions as initial symptom were retrospectively analyzed from August 2016 to January 2023 in Wuhan First Hospital and Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. RESULTS: Among the 11 patients, there were 6 males and 5 females, with a median age of 50(32-80) years. All patients had different forms of skin lesions as initial clinical symptom, including rash, ulcerative mass, painful skin nodules, infiltrating macula, etc. Most of the skin lesions were involved in the limbs and trunk but also appeared in the lower limbs alone. Five patients had hemophagocytic lymphohistiocytosis (HLH) at initial diagnosis, and 8 patients had B symptoms. All patients were diagnosed with advanced clinical staging (Lugano staging IV), and classified as high risk (PINK-E score ≥3). Immunohistochemical examination revealed that the positive rates of CD56 and EBER were both 100%, and the median Ki-67 index was 75%(50%-80%). Plasma EBV-DNA tests were all positive (≥5×10² copies/ml). Most of the induction chemotherapy regimens were combination chemotherapy (MESA, p-Gemox, SMILE) containing pegaspargase or L-asparaginase, or combined with PD-1 monoclonal immunotherapy, or HLH regimens (HLH-04 regimen, L-DEP). The median follow-up time and overall survival (OS) time were both 4.5(0.5-27) months. During the follow-up period, all 8 patients who did not receive autologous hematopoietic stem cell transplantation (ASCT) died, most of whom died of rapid disease progression. Three patients received ASCT, one died of central nervous system recurrence after transplantation, and two survived. The OS of three patients who underwent ASCT was 21, 27, and 19 months, and PFS was 11, 20, and 13 months, respectively. The plasma EBV-DNA copy number was monitored irregularly after transplantation, and the load of EBV was consistent with the changes of the disease. CONCLUSIONS Early clinical symptoms of ENKTL patients with skin lesions as initial symptom are more atypical, and early diagnosis is particularly difficult. The disease progresses rapidly and the prognosis is poor. There is still no uniform standard for the best treatment strategy. The survival of patients can be significantly prolonged by applying ASCT as soon as possible after complete remission obtained by high-dose induction chemotherapy.

Objective:To explore the causes and preventive measures of respiratory arrest following general anesthesia in children with obstructive sleep apnea （OSA）, in order to enhance the safety of OSA surgeries under general anesthesia. Methods:A retrospective analysis was conducted on the clinical and follow-up data of four pediatric cases that experienced respiratory arrest after general anesthesia for OSA at Shenzhen Hospital of Southern Medical University from March 2020 to March 2022. Results:All four children exhibited varying degrees of decreased blood oxygen saturation, cyanosis, and loss of consciousness after OSA surgery under general anesthesia, with one case experiencing respiratory and cardiac arrest. Through emergency rescue measures such as oxygen supplementation, suctioning, positive pressure ventilation, awakening, and cardiopulmonary resuscitation, all four children were stabilized. Follow-up after 2 to 6 months showed no complications. The main reasons for the occurrence are analyzed as: residual anesthetic drugs, characteristics of the OSA disease, and the unique aspects of the pediatric population. Conclusion:Children undergoing general anesthesia for OSA should be closely monitored for vital signs after surgery. If respiratory suppression occurs, active rescue measures should be taken to avoid serious consequences.

Targeting T-cell is a strategy to control allogeneic response disorders, such as acute graft-versus-host disease (GVHD) which is an important cause of therapy-failure after allogeneic hematopoietic cell transplants. Free fatty acid receptor-4 (FFAR4) is a regulator of obesity but its role in T-cell and allogeneic reactions is unknown. Here, we found knockout of Ffar4 in donor T-cells in a mouse allograft model increased acute GVHD whereas the natural FFAR4 ligands and the synthetic FFAR4 agonists decreased it. FFAR4 agonist-mediated anti-acute GVHD effects depended on FFAR4-expression in donor T-cells. The FFAR4 agonist CpdA suppressed donor T-cell-mediated alloreaction by activating an aryl hydrocarbon receptor (AhR) pathway. CpdA recruited β-Arrestin2 to FFAR4 which facilitated nuclear translocation of AhR and upregulation of IL-22. The CpdA-mediated anti-acute GVHD effect was absent in mice receiving Ahr-knockout or Il22-knockout T-cells. Recipient-expressing Ffar4 was also important for the anti-acute GVHD effect of CpdA which inhibited activation of antigen presenting cells. Importantly, CpdA decreased acute GVHD in obese mice, an effect also depended on Ffar4-expression in donor T-cells and recipients. Our study shows the immunoregulatory effect of FFAR4 in T-cell, and targeting FFAR4 might be a relative option for controlling allogeneic reactions in obese patients.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Objective:To retrospectively analyze the clinical efficacy and safety of biological agents in the treatment of psoriasis in the elderly.Methods:A retrospective study was conducted. A total of 124 patients aged ≥ 65 years with moderate-to-severe psoriasis (psoriasis area and severity index [PASI] score ≥ 3 points or body surface area [BSA] ≥ 3%), who were treated with biological agents at the Department of Dermatology and Venereology, People's Hospital of Xinjiang Uygur Autonomous Region, from June 2020 to December 2023, were collected. PASI, BSA, and dermatology life quality index (DLQI) scores were recorded at weeks 0 (pre-treatment), 4, 12, and 24 after the beginning of treatment to evaluate the efficacy. The proportions of patients achieving ≥ 75% and 90% improvements in PASI scores (PASI75 and PASI90, respectively) were calculated, and adverse reactions were recorded. Data were processed using SPSS 29.0 and GraphPad Prism 10.0 software. Normally distributed continuous variables were presented as mean ± standard deviation, while non-normally distributed continuous variables were presented as median with upper and lower quartiles ( Q1, Q3). Wilcoxon signed-rank test was used for comparisons of non-normally distributed data between groups, and chi-square test and Fisher's exact test were used for comparing categorical data. Results:Among the 124 patients, there were 72 males (58.1%) and 52 females (41.9%), and their ages ranged from 65 to 87 years. Treatment regimens included secukinumab for 86 patients (69.4%), ustekinumab for 15 (12.1%), ixekizumab for 14 (11.3%), guselkumab for 5 (4.0%), and adalimumab for 4 patients (3.2%). The pre-treatment PASI, BSA, and DLQI scores [ M ( Q1, Q3) ] were 12.2 (7.8, 19.6) points, 16.0% (10.2%, 25.0%), and 16 (11, 20) points respectively, which significantly decreased to 0.8 (0, 1.2) points, 1.0% (0, 2.0%), and 0 (0, 3) points respectively at week 24 after the start of treatment ( Z = 9.66, 9.66, 9.63, respectively, all P < 0.01). The proportions of patients achieving PASI75 at weeks 4, 12, and 24 were 42.7% (53/124), 80.6% (100/124), and 93.5% (116/124) respectively, and those achieving PASI90 were 13.7% (17/124), 48.4% (60/124), and 85.5% (106/124) respectively. There were no significant differences in the proportions of patients achieving PASI75 and PASI90 between the subgroups with and without comorbidities, as well as between the early-onset psoriasis subgroup and late-onset psoriasis subgroup at weeks 4, 12, and 24 (all P > 0.05). Among the 124 patients, 42 were followed up for over 2 years, and the proportions of patients achieving PASI75 and PASI90 after 2 years of treatment were 71.4% (30 cases) and 54.8% (23 cases), respectively. Adverse reactions occurred in 13 patients, including upper respiratory infections in 4 patients (3.2%), elevated aminotransferase levels in 3 patients (2.4%), eczematoid dermatitis in 2 patients (1.6%), pruritus in 2 patients (1.6%), nodular prurigo in 1 patient (0.1%), and vitiligo in 1 patient (0.1%) . Conclusion:Biological agents showed rapid and marked efficacy in the treatment of moderate-to-severe psoriasis in the elderly, with few and mild adverse reactions, suggesting high safety and overall marked efficacy.

Objective:To establish a complete system for the isolation, purification, identification, and culture of Kaposiform hemangioendothelioma-derived endothelial cells (KHE-ECs), to analyze the phenotype of KHE-ECs, and to explore the possibility of establishing a KHE-EC bank.Methods:A novel digestion solution for KHE tumors (patent number: CN202410500224.2) was formulated using collection fluid, Liberase TM and dispase stock solutions, and was used to process tumor tissues to obtain cells. High-purity KHE-ECs were purified using CD31 + immunomagnetic beads. The EGM-2 complete medium containing 10% fetal bovine serum and 2% penicillin-streptomycin solution was employed for cell culture. To verify the characteristics of KHE-ECs, immunofluorescence assay was conducted to determine the expression of endothelial cell-specific markers CD31 and CD34, KHE disease markers podoplanin (D2-40), prospero-related homeobox 1 (Prox-1), and lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1), as well as an infantile hemangioma-specific diagnostic marker glucose transporter 1 (GLUT-1). Human umbilical vein endothelial cells (HUVECs) served as controls for the phenotype analysis of KHE-ECs, including cell viability, cytoskeleton, proliferation, migration, invasion, tube formation, and sprouting ability. Results:Primary cells were successfully isolated from KHE tumor tissues, and high-purity KHE-ECs were obtained by using CD31 + immunomagnetic beads. The cells exhibited typical spindle-shaped morphology and an adherent growth pattern. Immunofluorescence assay showed that KHE-ECs expressed CD31, CD34, D2-40, Prox-1, and LYVE1, but did not express GLUT-1. There were significant differences in cell morphology, cell viability, and cytoskeletal structures between KHE-ECs and HUVECs. Additionally, the KHE-EC group showed significantly increased percentages of proliferative cells (29.1% ± 2.5%), numbers of migratory cells (114.3 ± 9.4) and invasive cells (110.0 ± 6.1), tube length (32 121.0 ± 892.0 μm), and number of sprouting cells (25.0 ± 3.6) compared with the HUVEC group (13.0% ± 2.2%, 38.0 ± 3.6, 35.3 ± 2.3, 25 345.0 ± 448.1 μm, 5.0 ± 1.0, respectively, all P ≤ 0.001) . Conclusion:An innovative digestion solution specifically for KHE tumors was formulated for the first time, and high-purity and well-growing KHE-EC strains were successfully isolated and purified by using the novel digestion solution in combination with CD31 + immunomagnetic beads, providing a stable and reliable cell source for subsequent experimental studies on KHE and laying the foundation for establishing a KHE-EC bank.
