[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.

Recently, male reproductive health has attracted extensive attention, with the adverse effects of circadian disruption on male fertility gradually gaining recognition. However, the mechanism by which circadian disruption leads to damage to male reproductive system remains unclear. In this review, we first summarized the dual regulatory roles of circadian clock genes on the male reproductive system: (1) circadian regulation of testosterone synthesis via the hypothalamic-pituitary-testicular (HPT) and hypothalamic-pituitary-adrenal (HPA) axes; (2) non-circadian regulation of spermatogenesis. Next, we further listed the possible mechanisms by which circadian disruption impairs male fertility, including interference with the oscillatory function of the reproductive system, i.e., synchronization of the HPT axis, crosstalk between the HPT axis and the HPA axis, as well as direct damage to germ cells by disturbing the non-oscillatory function of the reproductive system. Future research using spatiotemporal omics, epigenomic assays, and neural circuit mapping in studying the male reproductive system may provide new clues to systematically unravel the mechanisms by which circadian disruption affects male reproductive system through circadian clock genes.

BACKGROUND: Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease (CAD) remains incomplete. The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients. METHODS: In this retrospective cohort study, 25% of CAD patients without prior cancer history who underwent coronary artery angiography between January 1, 2011 and December 31, 2015, were randomly enrolled using SPSS 26.0. Patients were monitored for the incidence of postdischarge cancer, which was defined as cancer diagnosed after the index hospitalization, survival status and cause of death. Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients. RESULTS: A total of 4085 patients were included in the final analysis. During a median follow-up period of 8 years, 174 patients (4.3%) developed postdischarge cancer, and 343 patients (8.4%) died. A total of 173 patients died from cardiovascular diseases. Postdischarge cancer was associated with increased all-cause mortality risk (HR = 2.653, 95% CI: 1.727-4.076, P < 0.001) and cardiovascular mortality risk (HR = 2.756, 95% CI: 1.470-5.167, P = 0.002). Postdischarge lung cancer (HR = 5.497, 95% CI: 2.922-10.343, P < 0.001) and gastrointestinal cancer (HR = 1.984, 95% CI: 1.049-3.750, P = 0.035) were associated with all-cause mortality in CAD patients. Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients (HR = 4.979, 95% CI: 2.114-11.728, P < 0.001), and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer. CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients. Compared with other cancers, postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.

Objectives: To investigate whether the protective actions of ginsenoside Rb1 (Rb1) on astrocytes are mediated through the Gs-type G-protein-coupled receptor (GPCR-Gs). Methods: Primary astrocyte cultures derived from neonatal mouse brain were used. Astrocyte injury was induced via oxygen-glucose deprivation/re-oxygenation (OGD/R). Cell morphology, viability, lactate dehydrogenase (LDH) leakage, apoptosis, glutamate uptake, and brain-derived neurotrophic factor (BDNF) secretion were assessed to gauge cell survival and functionality. Western blot was used to investigate the cyclic adenosine monophosphate (cAMP) and protein kinase B (Akt) signaling pathways. GPCR-Gs-specific inhibitors and molecular docking were used to identify target receptors. Results: Rb1 at concentrations ranging from 0.8 to 5 μM did not significantly affect the viability, glutamate uptake, or BDNF secretion in normal astrocytes. OGD/R reduced astrocyte viability, increasing their LDH leakage and apoptosis rate. It also decreased glutamate uptake and BDNF secretion by these cells. Rb1 had protective effects of astrocytes challenged by OGD/R, by improving viability, reducing apoptosis, and enhancing glutamate uptake and BDNF secretion. Additionally, Rb1 activated the cAMP and Akt pathways in these cells. When the GPCR-Gs inhibitor NF449 was introduced, the protective effects of Rb1 completely disappeared, and its activation of cAMP and Akt signaling pathways was significantly inhibited. Conclusion Rb1 protects against astrocytes from OGD/R-induced injury through GPCR-Gs mediation.

Objective:Operational efficiency and influencing factors of China's basic medical insurance system from 2020 to 2021 is conducted to provide reference for improving the operational efficiency and optimizing the input-output relationship.Methods:The super-efficiency SBM model based on unexpected output and the Malmquist index are used to measure the static and dynamic efficiency of resident medical insurance in 31 provinces in China,and Tobit regression analysis is employed to analyze the influencing factors.Results:The overall operational efficiency of resident medical insurance still needs improvement.The operational efficiency of resident medical insurance in the central and western regions is lower than that in the eastern region,and the gap is significant.Different levels and regions have differentiated main constraints on the operational efficiency of resident medical insurance.In terms of dynamic efficiency,the total factor productivity of resident medical insurance operation shows an increasing trend,mainly due to technological progress.In terms of influencing factors,the degree of aging,the level of medical expenses and the level of medical insurance supervision have a significant impact on the operational efficiency.Suggestions:Efforts should be made to bridge regional disparities,promote the equitable development of medical insurance,reasonably control the level of medical expenses,strengthen the supervision of medical insurance funds,and implement active aging policies.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the clinical effect of perforator pedicled propeller flap (PPPF) in reconstruction of soft tissue defect in ankle and foot, as well as the role of preoperative ultrasonography in assistance of the location of perforators in donor site.Methods:From January 2017 to June 2023, the Department of Microorthopedics of the Second Affiliated Hospital of Luohe Medical College of Higher Education applied PPPF to reconstruct small and medium-sized soft tissue defects in the ankle and foot for 26 patients. The patients were 17 males, 9 females, aged 18 to 68 years old with 46 years old in average. The defect sites were 3 in forefoot and 6 in midfoot and combined with different degrees of tendon and bone exposure, 17 in ankle and heel and combined with various degrees of bone exposure, 12 with ankle open injury and 5 with Achilles tendon exposure. The area of soft tissue defects ranged from 2.5 cm×1.5 cm to 16.0 cm × 6.5 cm. The width of injury was measured before surgery, and a HHD was used to detect the perforators proximal to the defect site, and then high-frequency CDU was used to locate and confirm the location of the perforator and its alignment, blood flow and diameter. The line drawn between the 2 perforators was set as the axis of flap. The donor site was assessed by a "pinching and lifting" method to determine a direct closure of donor site or to have it closed by a flap transfer. The sizes of flap were from 2.8 cm×1.5 cm to 24.0 cm×7.5 cm. Twenty-two donor sites were directly closed and 4 received flap transfers. Four flaps had sutures with the skin nerves in the recipient site. Masquelet technique was performed in 6 patients with bone defects in the surgery. Patients received outpatient reviews with 1-2 weeks of intervals in the first 2 months after surgery, and X-ray reviews per 1-2 months for those with bone implants until bone healing.Results:All flaps survived successfully without any special treatment after surgery, except 1 flap that had blood vessel congestion and showed swelling and poor blood supply to the distal flap at 24 hours after surgery. The blood vessel congestion was revised by removal of part of the suture at the tip of flap pedicle. One week later, the tip of the flap remained with a small area of necrosis, which was then healed after dressing changes. A total of 21 patients were included in postoperative follow-up with 4 months to 3 years. All of the flaps had satisfactory appearance, colour and texture, and without any ulceration. Three cases of nerve suture were also included in follow-up. According to the assessment criteria of British Medical Research Council (BMRC), the sensory recovery of the flaps was found of S 2 in 1 flap and S 3 in 2 flaps. According to the American Orthopaedic Foot and Ankle Society (AOFAS), the ankle-hindfoot function scores, there were excellent in 16 patient and good in 5 patients. Conclusion:With the assistance of ultrasound, the PPPF can be effectively used in reconstruction of soft tissue defects in ankle and foot.
