ObjectiveTo investigate the effects of atorvastatin （ATV） on the proliferation and differentiation of rat bone marrow mesenchymal stem cells （BMSCs）， periodontal ligament stem cells （PDLSCs）， and dental pulp stem cells （DPSCs） in vitro， and to validate the regulatory effect of ATV on periodontal bone formation and tooth movement using a rat orthodontic tooth movement （OTM） model. MethodsThe effects of ATV on the proliferation and osteogenic/odontogenic differentiation of rat BMSCs， PDLSCs， and DPSCs were assessed in vitro. CCK-8 assay was used to detect the proliferation of the three types of cells. Alkaline phosphatase （ALP） staining and Alizarin Red staining were employed to evaluate osteogenic differentiation capacity. Western blot was used to detect the expression of osteogenesis-related proteins ［collagen type I （COL-I）， Runt-related transcription factor 2 （Runx2）， bone morphogenetic protein-2 （BMP-2）， osteocalcin （OCN）］ and the odontogenesis-related protein dentin sialophosphoprotein （DSPP） in BMSCs， PDLSCs and DPSCs. An OTM rat model was established， with rats randomly assigned to an ATV gavage group and a control group. The ATV gavage group received daily oral administration of ATV at a dose of 20 mg/kg， while the control group received an equal volume of solvent by gavage. Tooth movement distance was measured via Micro-CT on days 7， 14， and 21. Histomorphology of periodontal tissues was observed using Hematoxylin and Eosin （HE） staining and Masson staining. The gene and protein expression levels of osteogenic markers （BMP-2， Runx2， OCN） on the tension side of the first molar were detected by qRT-PCR and immunohistochemistry， respectively. ResultsATV at concentrations of 1×10⁻⁶ mol/L and 1×10⁻⁷ mol/L significantly promoted the proliferation and osteogenic/odontogenic differentiation of BMSCs， PDLSCs， and DPSCs， manifested as enhanced ALP activity， increased mineralized nodule formation， and up-regulated expression of osteogenic/odontogenic proteins COL-I， Runx2， BMP-2， OCN， and DSPP （P<0.001）. In the OTM model， compared with the control group， the ATV gavage group showed a significant reduction in tooth movement distance （P<0.05）， enhanced osteogenic activity in periodontal tissues， and significantly increased gene （P<0.001） and protein （P<0.05） expression of BMP-2， Runx2， and OCN on the tension side of the first molar. ConclusionATV enhances periodontal osteogenesis by promoting osteogenic/dentinogenic differentiation， thus inhibiting tooth movement.

Purpose: Colorectal cancer (CRC) often spreads to the liver, necessitating surgical treatment for CRC liver metastasis (CRLM). Iron-deficiency anemia is common in CRC patients and is associated with fatigue and weakness. This study investigated the effects of iron-deficiency anemia on the outcomes of surgical resection of CRLM. Methods: This population-based, retrospective study evaluated data from adults ≥20 years old with CRLM who underwent hepatic resection. All patient data were extracted from the 2005–2018 US National (Nationwide) Inpatient Sample (NIS) database. The outcome measures were in-hospital outcomes including 30-day mortality, unfavorable discharge, and prolonged length of hospital stay (LOS), and short-term complications such as bleeding and infection. Associations between iron-deficiency anemia and outcomes were determined using logistic regression analysis. Results: Data from 7,749 patients (representing 37,923 persons in the United States after weighting) were analyzed. Multivariable analysis revealed that iron-deficiency anemia was significantly associated with an increased risk of prolonged LOS (adjusted odds ratio [aOR], 2.76; 95% confidence interval [CI], 2.30–3.30), unfavorable discharge (aOR, 2.42; 95% CI, 1.83–3.19), bleeding (aOR, 5.05; 95% CI, 2.92–8.74), sepsis (aOR, 1.60; 95% CI, 1.04–2.46), pneumonia (aOR, 2.54; 95% CI, 1.72–3.74), and acute kidney injury (aOR, 1.71; 95% CI, 1.24–2.35). Subgroup analyses revealed consistent associations between iron-deficiency anemia and prolonged LOS across age, sex, and obesity status categories. Conclusion In patients undergoing hepatic resection for CRLM, iron-deficiency anemia is an independent risk factor for prolonged LOS, unfavorable discharge, and several critical postoperative complications. These findings underscore the need for proactive anemia management to optimize surgical outcomes.

Objective: To investigate the urban and rural differences in adverse outcomes of pulmonary tuberculosis (PTB) in patients with pulmonary tuberculosis-diabetes mellitus comorbidity (PTB-DM), so as to provide insights into improving the prevention and treatment measures for PTB-DM. Methods: Patients with PTB-DM who were admitted and discharged from 14 designated tuberculosis hospitals in Hangzhou City from 2018 to 2022 were selected. Basic information, and history of diagnosis and treatment were collected through hospital information systems. The adverse outcomes of PTB were defined as endpoints, and the proportions of adverse outcomes of PTB in urban and rural patients with PTB-DM were analyzed. Factors affecting the adverse outcomes of PTB were identified using a multivariable Cox proportional hazards regression model. Results: A total of 823 patients with PTB-DM were enrolled, including 354 (43.01%) urban and 469 (56.99%) rural patients. There were 112 (13.61%) patients with adverse outcomes of PTB. The proportions of adverse outcomes of PTB in urban and rural patients were 14.41% and 13.01%, respectively, with no statistically significant difference (P>0.05). Multivariable Cox proportional hazards regression analysis identified first diagnosed in county-level hospitals or above (HR=2.107, 95%CI: 1.181-3.758) and drug resistance (HR=3.303, 95%CI: 1.653-6.600) as the risk factors for adverse outcomes of PTB in urban patients with PTB-DM, while the treatment/observed management throughout the process (HR=0.470, 95%CI: 0.274-0.803) and fixed-dose combinations throughout the process (HR=0.331, 95%CI: 0.151-0.729) as the protective factors for adverse outcomes in rural patients with PTB-DM. Conclusions There are differences in influencing factors for adverse outcomes of PTB in urban and rural patients with PTB-DM. The adverse outcomes of PTB are associated with first diagnosed hospitals and drug resistance in urban patients, and are associated with the treatment/observed management and fixed-dose combinations throughout the process in rural patients.

Objective:To analyse the effect of ultrasound-guided percutaneous liver biopsy and the coaxial biopsy needle tract radiofrequency ablation on patients diagnosed with hepatocellular carcinoma who are considered to be at risk of bleeding.Methods:The data of 117 patients with hepatocellular carcinoma who underwent coaxial biopsy needle tract radiofrequency ablation after ultrasound-guided percutaneous liver biopsy in Peking University First Hospital from March 2019 to April 2023 were retrospectively analysed. There were 95 males and 22 females, with the age of (62.0±11.8) years. A comprehensive analysis was conducted on the following variables: the pre-puncture platelet count, the international standardised ratio, anticoagulation therapy, the haemoglobin (Hb) level, the success rate of the liver puncture, the qualified rate of liver puncture specimens, the number of puncture samples, the length of hospital stay, the Hb level after puncture, bleeding within 10 days post-operation, and complications after ablation, including biliary fistula, hemothorax and organ perforation.Results:Among the 117 patients, 60 cases (51.3%) had an international normalized ratio >1.1, 40 cases (34.2%) had thrombocytopenia, that is, <150×10 9/L, and 17 cases (14.5%) received continuous anticoagulation therapy before the operation. It is evident that all 117 patients successfully completed the ultrasound-guided percutaneous liver biopsy, and that all liver biopsy specimens were qualified. The absence of biliary fistula, hemothorax, organ perforation or death in the patients post-ablation was noted. According to the adverse event evaluation criteria, version 5.0, 113 cases (96.6%) were classified as grade 1 and 4 cases (3.4%) were classified as grade 3. The Hb concentration of patients with minor bleeding (grade 1) prior to puncture was (119.7±22.2) g/L, which was significantly higher than the Hb concentration of patients with severe bleeding (grade 3), (76.0±10.4) g/L ( t=3.92, P=0.010). A meticulous examination of the data revealed that there were no statistically significant differences between the two groups with regard to pre-puncture platelet count, pre-puncture international standardised ratio, pre-puncture proportion of receiving anticoagulant drugs, length of hospital stay and number of puncture samples (all P>0.05). Conclusion:For patients with hepatocellular carcinoma who are at risk of bleeding, ultrasound-guided percutaneous liver biopsy followed by coaxial biopsy needle tract radiofrequency ablation can obtain satisfactory liver tissue samples and is relatively safe. There were differences in hemoglobin levels before puncture among patients with different bleeding after puncture.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

BACKGROUND: Delayed platelet engraftment is a common complication after umbilical cord blood transplantation (UCBT), and there is no standard therapy. Avatrombopag (AVA) is a second-generation thrombopoietin (TPO) receptor agonist (TPO-RA) that has shown efficacy in immune thrombocytopenia (ITP). However, few reports have focused on its efficacy in patients diagnosed with thrombocytopenia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: We conducted a retrospective study at the First Affiliated Hospital of the University of Science and Technology of China to evaluate the efficacy of AVA as a first-line TPO-RA in 65 patients after UCBT; these patients were compared with 118 historical controls. Response rates, platelet counts, megakaryocyte counts in bone marrow, bleeding events, adverse events and survival rates were evaluated in this study. Platelet reconstitution differences were compared between different medication groups. Multivariable analysis was used to explore the independent beneficial factors for platelet implantation. RESULTS: Fifty-two patients were given AVA within 30 days post-UCBT, and the treatment was continued for more than 7 days to promote platelet engraftment (AVA group); the other 13 patients were given AVA for secondary failure of platelet recovery (SFPR group). The median time to platelet engraftment was shorter in the AVA group than in the historical control group (32.5 days vs . 38.0 days, Z  = 2.095, P  = 0.036). Among the 52 patients in the AVA group, 46 achieved an overall response (OR) (88.5%), and the cumulative incidence of OR was 91.9%. Patients treated with AVA only had a greater 60-day cumulative incidence of platelet engraftment than patients treated with recombinant human thrombopoietin (rhTPO) only or rhTPO combined with AVA (95.2% vs . 84.5% vs . 80.6%, P  <0.001). Patients suffering from SFPR had a slightly better cumulative incidence of OR (100%, P  = 0.104). Patients who initiated AVA treatment within 14 days post-UCBT had a better 60-day cumulative incidence of platelet engraftment than did those who received AVA after 14 days post-UCBT (96.6% vs . 73.9%, P  = 0.003). CONCLUSION Compared with those in the historical control group, our results indicate that AVA could effectively promote platelet engraftment and recovery after UCBT, especially when used in the early period (≤14 days post-UCBT).

This article aims to study the processing methods by exploring the main chemical constituents of Aconiti Lateralis Radix Praeparata and the toxicity-attenuating mechanisms. The relevant articles were retrieved from multiple databases with the time interval of 1960-2024, and the chemical constituents of Aconiti Lateralis Radix Praeparata and the toxicity-attenuating mechanisms of its processing methods were summarized. The review revealed that the chemical constituents of Aconiti Lateralis Radix Praeparata included 32 diester-type alkaloids, 36 monoester-type alkaloids, 43 alkanolamine-type alkaloids, and 8 lipid-type alkaloids. At the same time, other chemical constituents such as water-soluble alkaloids were also studied, and their pharmacological activities were summarized. The toxicity-attenuating mechanisms of the processing methods included constituent loss, hydrolysis, ester exchange, and ion-pair action. The processing methods of Aconiti Lateralis Radix Praeparata have developed from being traditional to modern, with simplified operation and increased retention amounts of active constituents, which have improved the efficacy of processed Aconiti Lateralis Radix Praeparata products and have facilitated the industrial production. However, the existing processing methods of Aconiti Lateralis Radix Praeparata cannot completely solve the problem of possible reduction in efficacy during toxicity attenuation. More toxicity-attenuating mechanisms and lipid-type alkaloids of Aconiti Lateralis Radix Praeparata should be explored, which is expected to reduce its toxicity while retaining its efficacy.
