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.

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.

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 investigate the optimal timing of oral propranolol treatment for proliferative infantile hemangiomas (IH) .Methods:A bidirectional cohort study was conducted. Infants with proliferative IH receiving oral propranolol treatment were collected from the Department of Pediatric Surgery, West China Hospital, Sichuan University between June 2015 and May 2019, and their general information and IH-related clinical data were analyzed. The primary outcome was the satisfactory regression rate of IH during 6-12 months of continuous oral propranolol treatment; secondary outcomes included the time to achieve satisfactory regression, incidence of adverse reactions, incidence of IH ulceration, and IH recurrence rate. Multivariate logistic regression was performed to identify factors influencing the satisfactory regression of IH after propranolol treatment, and a receiver operating characteristic (ROC) curve was employed to determine the optimal age for initiating propranolol therapy.Results:A total of 122 IH infants were enrolled in the study, including 32 males (26.2%) and 90 females (73.8%), with ages ( M[ Q1, Q3]) of 8.6 [6.3, 12.3] weeks. IH was located on the head and face in 56 cases (45.9%). There were 57 cases (46.7%) of localized IH, 53 (43.4%) of segmental IH, and 86 (70.5%) of mixed-type IH. Ulceration occurred in 17 cases (13.9%). After 6 months of propranolol treatment, 8 patients (6.6%) experienced treatment failure, and 12 (9.8%) experienced relapse within 6 months after discontinuation of propranolol. During 6 months of oral propranolol treatment, 56 infants (45.9%) experienced mild to moderate adverse reactions, with no drug-related deaths observed. Multivariate logistic regression analysis revealed that the age at initiation of propranolol treatment was an independent factor influencing satisfactory regression of IH ( OR = 0.879, 95% CI: 0.808 - 0.957). ROC curve analysis revealed that the optimal age for starting propranolol therapy was 9.9 weeks, with a sensitivity of 75.7% and a specificity of 61.5%. Infants aged ≤ 9.9 weeks (73 cases) had a significantly higher satisfactory regression rate (72.6% [53/73]) compared with those aged > 9.9 weeks (49 cases, 34.7% [17/49]; χ2 = 17.23, P < 0.001) ; the time to achieve satisfactory regression of IH was significantly shorter in the infants aged ≤ 9.9 weeks ( M[ Q1, Q3]: 46.0 [38.5, 48.0] weeks) than in those aged > 9.9 weeks (57.0 [40.0, 73.5] weeks; Z = -2.01, P = 0.045) . Conclusion:For IH infants requiring systemic therapy, initiation of oral propranolol before the age of 10 weeks appeared to improve the satisfactory regression rate of IH.
