[Objective] To evaluate the feasibility of a novel outpatient infusion model for blinatumomab in two acute lymphoblastic leukemia (ALL) patients, aiming to address challenges of poor treatment tolerance, high healthcare costs, and compromised quality of life, thereby providing clinical insights for broader adoption of this approach. [Methods] Two post-allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients undergoing blinatumomab maintenance therapy were selected to evaluate the efficacy of the outpatient infusion model. Patient selection criteria, nursing protocols, standardized workflows, and advancements in infusion practices were systematically analyzed combined with a review of global developments in this field. [Results] Both patients completed outpatient blinatumomab infusion without severe adverse events, demonstrating preliminary feasibility and safety of this model. The novel approach enhanced treatment convenience, reduced hospitalization costs, and improved quality of life. [Conclusion] Despite the limited sample size, this pilot study highlights the potential of outpatient blinatumomab administration as a viable alternative to traditional inpatient regimens.

Objective To evaluate the value of pre-ascent 6-minute walking test performed at a high altitude in predicting the incidence of acute mountain sickness(AMS)induced by rapid ascent to a very high altitude.Methods After baseline information was collected,participants completed the 6-minute walking test at a high altitude of 2 900 m.Then,they rapidly ascended to a very high altitude of 5 000 m.The Lake Louise score was recorded to assess AMS.Results The AMS group showed a shorter pre-ascent 6-minute walking distance(6MWD)at the high altitude than the non-AMS group[480.00(450.00,521.75)m vs.546.00(516.50,568.50)m,P=0.006].No difference was observed regarding the pre-ascent heart rate or peripheral oxygen saturation(both P>0.05).The pre-ascent 6MWD at the high altitude was negatively correlated with the Lake Louise score assessed after rapid ascent to the very high altitude(r=-0.497,P=0.012).Logistic regression analysis confirmed that the pre-ascent 6MWD at the high altitude was associated with the risk of AMS induced by rapid ascent to the very high altitude(OR=0.971,95% CI=0.947-0.996,P=0.022).The results indicated that the pre-ascent 6MWD demonstrated ideal prediction performance(area under receiver operating characteristic curve=0.846,P=0.006).Conclusion The pre-ascent 6MWD recorded at the high altitude is a convenient and reliable predictor of the AMS induced by rapid ascent to the very high altitude.

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Objective: To investigate the association between prealbumin and the long-term prognosis of patients with hilar cholangiocarcinoma(HCCA) following radical surgery. Methods: The clinical data of 262 HCCA patients who underwent radical surgery admitted from January 2010 to January 2017 at the First Affiliated Hospital of Army Medical University were collected,retrospectively. There were 158 males and 104 females; aged (57.6±9.9)years old(range:32 to 78 years). According to the preoperative serum prealbumin level(170 mg/L),the patients were divided into low prealbumin group(n=143) and normal prealbumin group(n=119). Follow-up until September 2020,the main research indicator was overall survival(OS), and the secondary research indicator was recurrence-free survival(RFS). The measurement data conforming to the normal distribution adopted the t test,the measurement data not conforming to the normal distribution adopted the Mann-Whitney U test,and the count data adopted the χ² test. The Kaplan-Meier method was used to calculate the cumulative survival rate. The Log-rank test was used for univariate analysis of the cumulative survival rate. Variables with P<0.10 in univariate analysis were included in the Cox proportional hazards model for multivariate analysis. Results: The 1-, 3-, and 5-year OS rate of the 262 patients was 73.4%, 32.1%, and 24.0%, respectively, and the 1-, 3-, and 5-year RFS rate was 54.6%, 25.2%, and 16.2%, respectively. Median OS and RFS were 21 months and 12 months for patients with low prealbumin and 25 months and 19 months for patients with normal prealbumin. The OS rate and RFS rate of patients in the low prealbumin group were lower than those in the normal prealbumin group, and the difference was statistically significant (both P<0.05). The results of univariate analysis indicated that low prealbumin, CA19-9>150 U/L, tumor infiltration length>3 cm, preoperative jaundice, macrovascular invasion, microvascular invasion, lymph node metastasis, and poor differentiation maybe the risk factors of OS,and low prealbumin,tumor invasion length>3 cm,macrovascular invasion, microvascular invasion,lymph node metastasis,and poor differentiation maybe the risk factors of RFS for postoperative for radical resection in patients with HCCA (all P<0.10). Multivariate results suggested that low prealbumin,tumor invasion length>3 cm,microvascular invasion,lymph node metastasis,and poor differentiation were independent risk factors affecting OS and RFS in patients with HCCA after radical operation (all P<0.05). Conclusion: Preoperative prealbumin level can predict the long-term prognosis of patients with hilar cholangiocarcinoma following radical surgery.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

Objective    To determine whether there was a clinical relevant association between anesthetic regimen (propofol or inhalational anesthetics) and the occurrence of postoperative delirium (POD) in patients undergoing cardiac surgery. Methods    This retrospective study was conducted on patients with elective cardiac surgery under cardiopulmonary bypass (CPB) at West China Hospital of Sichuan University between October 2018 and March 2019. The patients were divided into a propofol group or an inhalational anesthetics group according to anesthetic regimen (including CPB). The primary outcome was the occurrence of POD during first 3 days after surgery. Logistic regression analysis was used to determine the relationship between anesthetic regimen and the occurrence of POD. Results    A total of 197 patients who met the inclusion criteria were included, with an average age of 53 years, and 51.8% (102/197) were females. POD occurred in 21.3% (42/197) patients. The incidence of POD was 21.4% in the propofol group and 21.2% in the inhalational anesthetics group; there was no significant difference between the two groups (RR=1.01, 95%CI 0.51-2.00, P=0.970). Logistic regression analysis did not find that anesthetic regimen was a risk factor for delirium after cardiac surgery after adjusting risk factors (OR=1.05, 95%CI 0.48-2.32, P=0.900). Conclusion    Anesthetic regimen (propofol or inhalational anesthetics) is not associated with an increased risk for POD in adult patients undergoing elective cardiac surgery under CPB.

Objective    To evaluate the association of anesthesia regime (volatile or intravenous anesthetics) with the occurrence of postoperative pulmonary complications (PPCs) in adult patients undergoing elective cardiac surgery under cardiopulmonary bypass (CPB). Methods    The electronic medical records of 194 patients undergoing elective cardiac surgery under CPB at West China Hospital, Sichuan University between September 2018 and February 2019 were reviewed, including 92 males and 102 females with an average age of 53 years. The patients were classified into a volatile group (n=94) or a total intravenous anesthesia (TIVA) group (n=100) according to anesthesia regimen during surgery (including CPB). The primary outcome was the incidence of PPCs within first 7 d after surgery. Secondary outcomes included incidence of reintubation, duration of mechanical ventilation, ICU stay and hospital stay. Results    There was no significant difference in the incidence of PPCs between the two groups (RR=1.020, 95%CI 0.763-1.363, P=0.896), with an incidence of 48.9% in the volatile group and 48.0% in the TIVA group. Secondary outcomes were also found no significant difference between the two groups (P>0.05). Conclusion    No association of anesthesia regimen with the incidence of PPCs is found in adult patients undergoing elective cardiac surgery under CPB.
