Objective: To explore the application effectiveness of healthcare failure mode and effect analysis (HFMEA) in optimizing intelligent blood logistics transport pathways for safety assurance. Methods: Data from 1 851 cases of intelligent blood logistics transport were collected between September 2023 and March 2025. Based on the implementation phases of HFMEA measures, the cases were divided into a control group (n=120), observation group 1 (n=219), and observation group 2 (n=1 512). Through systematic analysis of the transport processes, hazard scoring and decision tree analysis were conducted for each process, and phased optimization measures were implemented for high-risk failure modes. Results: The transport duration of intelligent blood logistics was 35.5 (20.8, 71.1) min in the control group, 25.1 (10.9, 40.7) min in observation group 1, and 9.9 (4.2, 44.5) min in observation group 2. Observation group 2 exhibited significantly shorter transport time compared to both observation group 1 and the control group, with statistically significant differences between groups (P<0.000 1). Conclusion: The implementation of HFMEA-driven measures significantly reduced intelligent blood logistics transport duration, thereby fostering the evolution of smart hospital ecosystems while enhancing healthcare service quality and operational efficiency.

Objective: To establish a radio frequency identification (RFID) technology-based emergency release process of uncrossmatched type O red blood cells for trauma patients, thereby providing a reference method for blood inventory management. Methods: The medical records of uncrossmatched type O red blood cell suspension released from Jan 2023 to Dec 2024 were retrospectively analyzed. The pre-implementation (2023, n=23) and post-implementation (2024, n=19) data of the RFID technology-based emergency uncrossmatched transfusion management method were compared to evaluate its effectiveness. Results: During the study period, 42 patients received a total of 92 units uncrossmatched type O red blood cell suspensions in emergency, with no case of hemolytic transfusion reactions reported. Traffic accidents were the primary cause of emergency uncrossmatched transfusion, accounting for 66.7% (28/42) of cases. The patients in observation group were significantly older than those in the control group (60.58y vs 48y, P<0.05), with a trend toward more critical trauma conditions (84.2% vs 56.5%, P=0.053). Among 29 critically injured patients, the blood release time in the observation group was significantly shorter than that in the control group (2 min vs 4 min, P<0.05). After excluding deceased patients, the observation group showed shorter hospitalization duration compared to the control group (18.5 d vs 35.58 d, P<0.05). Patients treated with a high red blood cell-to-plasma ratio demonstrated a significantly higher resuscitation success rate compared to those with a low ratio (64.3% vs 30%, P<0.05). Conclusion: The implementation of the RFID technology-based emergency uncrossmatched transfusion management method can significantly reduce the blood release time, shorten average hospitalization duration, improve treatment efficiency, and ensure transfusion safety for trauma emergency patients.

This study was designed to investigate the potential protective effect of isopimpinelline against para-chlorophenylalanine(PCPA)-induced pineal gland damage in rats.Forty male Sprague-Dawley(SD)rats were divided into four groups(n=10 each):a normal group,a model group,a melatonin-treated group(10 mg/kg),and an isopimpinelline-treated group(1.5 mg/kg).All groups,except for the normal,received intraperitoneal injection of PCPA(450 mg/kg)to induce pineal gland damage.Subsequent treatments were administered orally for 7 days.Sleep latency and duration were evaluated on the sixth day using the pentobarbital sodium sleep synergy test.After the treatment period,serum melatonin levels and pineal gland inflammation markers were assessed alongside oxidative and antioxidative parameters.Histological examinations of the pineal gland were conducted,and the expression of proteins related to the Nrf2 and NF-κB signaling pathways were quantified.Data showed that isopimpinelline alleviates the structural damage in the pineal gland of model rats,significantly elevated serum melatonin levels,and markedly improved sleep latency and duration(P＜0.05).Isopimpinelline activated the Nrf2 signaling pathway by inhibiting Keap1 expression,which facilitated the nuclear translocation of Nrf2 and upregulated the antioxidant proteins NQO1 and HO-1,thereby mitigating oxidative stress in the pineal gland(P＜0.05).Furthermore,isopimpinelline significantly reduced the levels of pro-inflammatory cytokines IL-2,TNF-α and IL-6.Isopimpinelline also suppressed the NF-κB signaling pathway,reducing the expression of NF-κB p65,IKKβ,and p-IKKβ proteins,as well as the nuclear translocation of NF-κB p65(P＜0.05),thereby providing anti-inflammatory benefits.In conclusion,isopimpinelline could protect pineal gland from damage by activating the Nrf2 signaling pathway and inhibiting the NF-κB pathway.

OBJECTIVETo evaluate the clinical effects on incomplete intestinal obstruction treated with the adjuvant therapy of acupuncture and moxibustion.

METHODSUsing the retrospective analysis, 80 patients of incomplete intestinal obstruction were divided into an observation group and a control group, 40 cases in each one. In the control group, the routine treatment was given, such as fasting, gastrointestinal decompression, parenteral nutrition, infection prevention with antibiotics and enema laxative. In the observation group, on the basis of the treatment as the control group, acupuncture was applied at bilateral Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39); moxibustion was used at left Yangchi (TE 4), Zhongwan (CV 12), Qihai (CV 6) and Guanyuan (CV 4). The treatment was given once a day, 30 min each time. The average days of treatment, the surgical transfer rate, the time to first flatus, the recovery time of defecation and the time of solid food intake were observed in the patients of the two groups.

RESULTSThe average days of treatment in the observation group was obviously less than that in the control group (<0.05). The surgical transfer rate in the observation group was obviously lower than that in the control group (<0.05). The time to first flatus, the recovery time of defecation and the time of solid food intake were all obviously earlier than those in the control group (all <0.05).

CONCLUSIONThe adjuvant therapy of acupuncture and moxibustion achieves the significant therapeutic effects on incomplete intestinal obstruction, shortens the treatment duration and reduces the surgical transfer rate and the patient's economic burden.

Objective To investigate the effect of miR-132-3p on the proliferation of endothelial progenitor cells and its regulatory mechanism in order to provide a new theoretical basis for the treatment of deep venous thrombosis. Methods Real-time quantitative PCR (qPCR) was used to detect the expression of miR-132-3p in the plasma and endothelial progenitor cells of 27 healthy volunteers and 22 thrombus patients, and in endothelial progenitor cells under normoxic and hypoxic conditions. The miR-132-3p analogue and the specific siRNA were transferred into endothelial progenitor cells by the electroporation method. The effect of miR-132-3p on the proliferation of endothelial progenitor cells was detected using MMT and Cell Counting Kit-8 (CCK-8) methods. The effects of miR-132-3p on the expression of FOXO1 in endothelial cells were analyzed using the luciferase assay and western blots. Results The expression of miR-132-3p in clinical patients with thrombosis was significantly decreased to 0.45 ± 0.05 times of that of the healthy volunteers (P＜0.05). The expression of miR-132-3p in endothelial progenitor cells under hypoxia was down-regulated to (0.23 ± 0.13) times of that of under normoxia (P＜0.05). The expression of miR-132-3p of experiment group under hypoxia was up-regulated to (15.72 ± 2.06) times of that of control group (P＜0.05). MMT assay showed that the proliferation of cells in the experimental group under hypoxic condition was up-regulated to (7.79 ± 1.37) times of that in the control group (P＜0.01). CCK-8 assay showed that cell proliferation in experimental group was up-regulated to (6.46 ± 0.38) times of that in the control group (P＜0.01). Software analysis showed that FOXO1 was a direct target of miR-132-3p. Luciferase activity of miR-132-3p mimics transfected endothelial progenitor cells under hypoxic conditions were 0.47 times of that in siRNA treatment group. Western blot showed that the expression of FOXO1 protein in endothelial progenitor cells transfected with miR-132-3p mimics in hypoxia was 0.18 times of that in siRNA treatment group. Conclusions Compared with healthy volunteers, miR-132-3p expression in the blood of patients with thrombosis was significantly reduced that can promote transcription of the FOXO1 gene (and protein expression) and inhibit the proliferation of endothelial progenitor cells. It could be closely related to the formation of venous thrombosis.
