Osteosarcoma (OS) is the most common primary malignant bone tumor in clinic. It has high mortality and disability rate. Effective neoadjuvant chemotherapy combined with limb salvage surgery can improve the 5-year survival rate of OS patients. Drug resistance or low sensitivity of tumor cells is the most common cause of postoperative local recurrence and metastasis. Therefore, the sensitivity of OS cells to chemotherapy drugs is of great value to the prognosis of the patients. In recent years, traditional Chinese medicine has been widely used because of high efficiency and low toxicity. A large number of studies have confirmed that part of traditional Chinese medicine can reverse the chemotherapy resistance of OS cells by regulating the ABC transmembrane transport protein system. This article gives an overview of its related mechanisms and latest developments.

The improvement of survival of osteosarcoma patients by the standard treatment strategy of osteosarcoma(neoadjuvant chemotherapy+surgical treatment+adjuvant chemotherapy)has been stabilized in the past 20 years,and the emergence of the slow(controlled)-release drug delivery system has provided a new strategy for the treatment of osteosarcoma.At present,thanks to the development of nanotechnology,great progress had been made to the technology of slow-release chemotherapy for osteosarcoma in China,but the clinical translation of the slow-release chemotherapy system has become the key to constrain its development.Based on this,this review summarizes the preclinical research progress of the main chemotherapeutic agents for osteosarcoma,including methotrexate,doxorubicin,cisplatin,and isocyclophosphamide,in the recent years,with the expectation of clarifying the safety and efficacy of the slow-release chemotherapy system for osteosarcoma,and facilitating the clinical translation of the slow-release chemotherapy system for osteosarcoma.

Objective:To analyze the influence of factors before initiation of extracorporeal cardiopulmonary resuscitation (ECPR) on the prognosis of patients, so as to explore the intervention timing and improvement strategy of ECPR.Methods:A retrospective analysis was performed on 29 patients who underwent ECPR in the First Affiliated Hospital of Hunan Normal University (Hunan people's Hospital)from July 2018 to April 2021. Patients were divided into the survival group ( n = 13) and death group ( n = 16) according to whether they survived at discharge. The duration of conventional cardiopulmonary resuscitation (CCPR), initial heart rate before ECPR, the ratio of out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA), and the ratio of transported cases outside the hospital were compared between the two groups. According to different CCPR time, the patients were divided into the ≤45 min group, 45-60 min group and >60 min group to compare the hospital survival and sustained return of spontaneous circulation (ROSC) rate . According to the location of cardiac arrest, the patients from emergency department and other department were divided to compare the survival of IHCA. Results:The total survival rate was 44.83%, the average duration of extracorporeal membrane oxygenation (ECMO) was 114 (33.5, 142.5) h, and the average duration of CCPR time was 60 (44.5, 80) min. The duration of ECMO was longer in the survival group than in the death group ( P = 0.001). The duration of CCPR (the time from CPR to ECMO) in the survival group was significantly shorter than that in the death group ( P = 0.010). Patients with defibrillatory rhythm had higher hospital survival rate ( P = 0.010). OHCA patients had higher mortality than IHCA patients ( P = 0.020). Mortality of patients transferred from other hospitals was higher ( P = 0.025). Hospital survival and ROSC decreased in turn by CCPR duration ≤ 45 min, 45-60 min, and > 60 min ( P = 0.001). The location of CA occurrence had no impact on the hospital survival rate of IHCA patients ( P=0.54). Conclusions:Hospital survival of ECPR is higher than that of CCPR. ECPR is effective for refractory cardiac arrest. The prognosis of ECPR is significantly related to the duration of CCPR, initial heart rate, and location of CA. Education and team training should be strengthened to improve the survival rate of ECPR.

Linear chromatin is compacted into eukaryotic nucleus through a complex and multi-layered architecture. Consequently, chromatin conformation in a local or long-distance manner is strongly correlated with gene expression. Chromosome conformation capture (3C) technology, together with its variants like 4C/5C/Hi-C, has been well developed to study chromatin looping and whole genome structure. In this review, we introduce new technologies including chromosome capture combined with immunoprecipitation, nuclei acid-based hybridization, single cell and genome sequencing, as well as their application.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

OBJECTIVE: To analyze the predictors of successful weaning off extracorporeal membrane oxygenation (ECMO) after extracorporeal cardiopulmonary resuscitation (ECPR). METHODS: The clinical data of 56 patients with cardiac arrest who underwent ECPR in Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from July 2018 to September 2022 were retrospectively analyzed. According to whether ECMO was successfully weaning off, patients were divided into the successful weaning off group and the failed weaning off group. The basic data, duration of conventional cardiopulmonary resuscitation (CCPR, the time from cardiopulmonary resuscitation to ECMO), duration of ECMO, pulse pressure loss, complications, and the use of distal perfusion tube and intra-aortic balloon pump (IABP) were compared between the two groups. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors for weaning failure of ECMO. RESULTS: Twenty-three patients (41.07%) were successfully weaned from ECMO. Compared with the successful weaning off group, patients in the failed weaning off group were older (years old: 46.7±15.6 vs. 37.8±16.8, P < 0.05), higher incidence of pulse pressure loss and ECMO complications [81.8% (27/33) vs. 21.7% (5/23), 84.8% (28/33) vs. 39.1% (9/23), both P < 0.01], and longer CCPR time (minutes: 72.3±19.5 vs. 54.4±24.6, P < 0.01), shorter duration of ECMO support (hours: 87.3±81.1 vs. 147.7±50.8, P < 0.01), and worse improvement in arterial blood pH and lactic acid (Lac) levels after ECPR support [pH: 7.1±0.1 vs. 7.3±0.1, Lac (mmol/L): 12.6±2.4 vs. 8.9±2.1, both P < 0.01]. There were no significant differences in the utilization rate of distal perfusion tube and IABP between the two groups. Univariate Logistic regression analysis showed that the factors affecting the weaning off ECMO of ECPR patients were pulse pressure loss, ECMO complications, arterial blood pH and Lac after installation [pulse pressure loss: odds ratio (OR) = 3.37, 95% confidence interval (95%CI) was 1.39-8.17, P = 0.007; ECMO complications: OR = 2.88, 95%CI was 1.11-7.45, P = 0.030; pH after installation: OR = 0.01, 95%CI was 0.00-0.16, P = 0.002; Lac after installation: OR = 1.21, 95%CI was 1.06-1.37, P = 0.003]. After adjusting for the effects of age, gender, ECMO complications, arterial blood pH and Lac after installation, and CCPR time, showed that pulse pressure loss was an independent predictor of weaning failure in ECPR patients (OR = 1.27, 95%CI was 1.01-1.61, P = 0.049). CONCLUSIONS Early loss of pulse pressure after ECPR is an independent predictor of failed weaning off ECMO in ECPR patients. Strengthening hemodynamic monitoring and management after ECPR is very important for the successful weaning off ECMO in ECPR.
