OBJECTIVE To build a new workflow of pharmacy intravenous admixture services (PIVAS), effectively connect intelligent equipment, and promote the intelligent development of PIVAS. METHODS Based on intelligent auxiliary equipment, PIVAS workflow was optimized, and a process-oriented model was established. This model integrated intelligent prescription review (automatic prescription review+manual intervention mode), intelligent labeling, intelligent allocation, intelligent sorting, and finished infusion quality inspection system. Furthermore, an assessment was conducted to examine unreasonable medical order rate of intelligent prescription review, the working efficiency and error rate of intelligent labeling machine and intelligent sorting machine, and the dispensing efficiency and accuracy of intelligent dispensing robot. RESULTS Under the intelligent prescription review mode, the rate of unreasonable medical orders decreased from 0.157% to 0.050% (P<0.05); automatic labeling efficiency reached 21.7 sheets/min, surpassing the manual labeling efficiency of 13.8 sheets/min (P<0.05), and the daily labeling error rate decreased from 6.1‰ to 2.5‰ (P<0.05). Simultaneously operating two dispensing robots significantly improved the efficiency of batch dispensing and reduced the residual amount of liquid medicine (P<0.05); additionally, a quality testing system for finished infusion was established, involving appearance, Tyndall effect, insoluble particles, turbidity, absorbance, pH and osmotic pressure, to ensure the quality of finished infusion and reduce the risk of infusion. CONCLUSIONS The new process of PIVAS connected with intelligent devices in our hospital can improve work efficiency, reduce dispensing errors, ensure the quality of finished infusion, and improve the level of pharmaceutical care.

Onco-critical care has emerged as an important subspecialty at the intersection of critical care medicine and oncology, attracting increasing attention in recent years. With continuous innovations in cancer therapies, patient survival has improved significantly; however, the incidence of associated critical complications has also increased. The reasons for cancer patients requiring intensive care unit admission are diverse and can be broadly categorized into three groups: progression of the underlying malignancy, treatment-related complications, and coexisting classical critical illnesses. Traditional critical care concepts and practices face limitations in addressing the multidimensional and heterogeneous challenges of onco-critical care. Based on the core mechanism of critical illness development—host/organ unregulated response (HOUR)—this article systematically elaborates on how this framework advances understanding and clinical practice into onco-critical care, with emphasis on its manifestations in neuroendocrine, immune-inflammatory, and coagulation-metabolic pathways. The review summarizes recent advances in clinical assessment and phenotyping systems for onco-critical illness and discusses a multidisciplinary, integrated management strategy centered on the "Disease Control, Host Response Modulation, Organ Support" triad. Finally, major challenges and future directions in this field are outlined. By integrating existing evidence and theoretical insights, this review aims to provide new perspectives and a theoretical foundation for the clinical management of onco-critical illness, thereby promoting its evolution toward precision and standardization.

With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

OBJECTIVE To compare the efficacy and safety of tildrakizumab versus secukinumab in the treatment of moderate-to-severe plaque psoriasis. METHODS A retrospective analysis was conducted on 141 patients with moderate-to-severe plaque psoriasis treated at the First Affiliated Hospital of Nanyang Medical College from January 2024 to April 2025. According to the treatment regimen,the patients were divided into tildrakizumab g roup ( n =61) and secukinumab group ( n =80). The PASI 75,PASI 90,and PASI 100 response rates, the Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores, skin barrier function (sebum content and stratum corneum water content), inflammatory factor levels [interleukin-17 (IL-17), tumor necrosis factor-α (TNF-α), and IL-23 ] before and after treatment, and the incidence of adverse drug reactions during treatment were compared between the two groups. RESULTS After 12 weeks of treatment, the PASI 75, PASI 90, and PASI 100 response rates in the tildrakizumab group were significantly higher than those in the secukinumab group ( P <0.05). After treatment, PASI and DLQI scores as well as serum levels of IL-17, TNF-α, and IL-23 in both groups were significantly reduced compared to before treatment in the same group; sebum content and stratum corneum water content were significantly increased compared to before treatment in the same group ( P <0.05); the tildrakizumab group showed better results than the secukinumab group ( P <0.05). The overall incidence of adverse drug reactions was also significantly lower in the tildrakizumab group compared with the secukinumab group ( P <0.05). CONCLUSIONS Compared with secukinumab, tildrakizumab demonstrates superior efficacy in the treatment of moderate-to-severe plaque psoriasis, providing improved symptom relief, enhanced skin barrier function, reduced levels of inflammatory factors, and higher safety.

ObjectiveTo investigate the effect and mechanism of long intergenic non-coding RNA02086 (LINC02086) overexpression mediated macrophage polarization on the proliferation, migration and invasion of gastric cancer cells. MethodsThe expression levels of LINC02086 in the human gastric epithelial cell line GES-1 and human gastric cancer cell lines HCG-27, NCI-N87, and AGS were determined by qRT-PCR. Human acute monocytic leukemia cells (THP-1) were induced to differentiate into M0 macrophages using phorbol 12-myristate 13-acetate (PMA). HGC-27 cells were infected with either LINC02086 overexpression lentivirus (OE-LINC02086) or its negative control lentivirus (Vector), and the culture supernatants were collected as conditioned medium (CM1). M0 macrophages were co-cultured with the infected HGC-27 cells, and the resulting supernatants were designated as conditioned medium 2 (CM2). M0 macrophages were treated with CM1 alone or in combination with Wnt/β-catenin pathway inhibitor IWR-1, forming the Vector+CM1, OE-LINC02086+CM1, and OE-LINC02086+CM1+IWR-1 groups, respectively. Flow cytometry was used to detect mannose receptor C-type 1 (CD206) expression, and qRT-PCR was employed to measure mRNA levels of interleukin-10 (IL⁃10), transforming growth factor-β (TGF⁃β), vascular endothelial growth factor (VEGF), and chemokine ligand 22 (CCL22). Western blot was performed to evaluate protein expression of CD206, VEGF, and key components of the Wnt/β-catenin pathway—Wnt family member 3a (Wnt3a), glycogen synthase kinase-3β (GSK-3β), and β-catenin. HGC-27 cells were treated with CM2 alone or combined with IWR-1, establishing the Vector+CM2, OE-LINC02086+CM2, and OE-LINC02086+CM2+IWR-1 groups. CCK-8 assay was used to evaluate cell proliferation, and Transwell assays were conducted to assess migration and invasion capabilities. ResultsCompared with GES-1 cells, the expression levels of LINC02086 were upregulated in HCG-27, NCI-N87, and AGS cells (P < 0.05), with the smallest increase observed in HCG-27 cells. Compared with Vector+CM1 group, the level of CD206 and the expression levels of IL⁃10, TGF⁃β, VEGF and CCL22 mRNA in macrophages stimulated by OE-LINC02086+CM1 increased (P<0.05). Meanwhile, the expression levels of Wnt3a and β-catenin proteins in cells increased (P<0.05), and the expression level of GSK-3β protein decreased (P<0.05). However, co-treatment with IWR-1 markedly reversed the promoting effects of LINC02086 overexpression on the expression of M2 polarization markers, including CD206, IL⁃10, and TGF⁃β mRNA, in macrophages (P<0.05), as well as its activation of the Wnt/β-catenin signaling pathway (P<0.05). Compared with Vector+CM2 group, HGC-27 cells infected with OE-LINC02086+CM2 had increased proliferation activity and increased number of migration and invasion cells (P<0.05). However, the combined intervention of IWR-1 significantly reversed the promotion of LINC02086 overexpression on the proliferation, migration and invasion of HGC-27 cells (P<0.05). ConclusionLINC02086 overexpression promotes the proliferation, migration and invasion of gastric cancer cells by activating Wnt/β-catenin pathway to mediate M2 polarization of macrophages.

ObjectiveThe widespread adoption of portable fundus cameras for primary care and community screening is hindered by limitations in current autofocus(AF) technologies. Image-based methods relying on sharpness evaluation require iterative searches, resulting in slow convergence, while projection-based techniques are susceptible to optical artifacts and calibration errors. To address these challenges, this study introduces a novel AF system based on direct wavefront sensing, designed to deliver simultaneous high speed, high precision, and operational robustness within the compact form factor essential for portable ophthalmic devices. MethodsOur approach fundamentally reimagines the AF process by directly measuring the ocular wavefront aberration. We developed a custom portable fundus camera integrating a miniaturized Shack-Hartmann wavefront sensor (SHWS) into the optical path. An 850 nm laser diode projects a point source onto the retina via oblique illumination to minimize corneal reflections. Light scattered from this spot carries the eye’s refractive error through the imaging optics and is directed to the SHWS, positioned at a plane optically conjugate to the primary color CMOS imaging sensor. A microlens array within the SHWS samples the incident wavefront, generating a pattern of focal spots on a CCD. Real-time centroid analysis of these spots provides a map of local wavefront slopes. These measurements are processed through a singular value decomposition (SVD) algorithm to fit a Zernike polynomial basis set, enabling real-time reconstruction of the wavefront phase. The defocus component (S) is extracted from the second-order Zernike coefficients, providing a direct, quantitative measure of the refractive error in diopters. This value serves as a precise error signal in a closed-loop control system, which commands a voice-coil actuated focusing lens to its null position in a single, deterministic step, eliminating the need for iterative search algorithms. ResultsComprehensive evaluation demonstrated the system’s high performance. Testing on a calibrated model eye (OEMI-7) established a highly linear relationship between the computed defocus S and the focusing lens position across a ±20 Diopter (D) compensation range, achievable within a 5 mm mechanical travel. The system achieved a focusing precision of 0.08 D, corresponding to an 18-fold improvement over a conventional projection spot-size method tested under identical conditions. The total focus acquisition time, encompassing wavefront measurement, computation, and lens actuation, averaged under 0.5 s. Clinical validation with 25 human volunteers (50 eyes, refractive range -15 D to +10 D) confirmed practical efficacy. The wavefront-sensing AF succeeded in 92% of attempts with a mean time of 0.5 s, substantially outperforming a projection-based benchmark which achieved only a 32% success rate with an average time of 4.25 s. The system provided instantaneous directional guidance and maintained stability during minor ocular movements. Objective assessment of image quality, via amplitude contrast of retinal vasculature, showed consistent and significant enhancement following AF correction across the entire tested diopter range. ConclusionThis work successfully implements and validates a direct wavefront-sensing autofocus paradigm for portable fundus cameras. By directly quantifying and compensating for the optical defocus aberration, this method bypasses the fundamental limitations of image-processing and projection-based techniques, enabling rapid, precise, and deterministic diopter compensation. The developed system delivers an exceptional combination of a wide operational range (±20 D), high accuracy (0.08 D), fast convergence (0.5 s), and a compact physical footprint. This technology provides a practical and high-performance focusing solution capable of enhancing the reliability, throughput, and diagnostic utility of portable retinal imaging in large-scale screening applications. Future efforts will be directed towards system cost optimization and performance adaptation for diverse ocular conditions.

ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction (小青龙汤, XD) in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group, a model group, a loratadine group, low-, medium- and high-dose XD groups, and low-, medium- and high-dose Mahuang Decoction and Cang'erzi Powder (麻黄汤合苍耳子散, MDCP) groups. Except for the control group, rats were administered with ovalbumin (OVA) and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection, nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/(kg·d) of saline, whereas those in the loratadine group were administered with 0.9 mg/(kg·d) of loratadine. The low-, medium- and high-dose XD groups were administered XD at the dose of 2.7, 5.4, and 10.8 g/(kg·d), respectively. The low-, medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43, 4.86, and 9.72 g/(kg·d), respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage, nasal symptom scores were recorded for all group of rats. The next day, serum levels of immunoglobulin E (IgE), interleukin-4 (IL-4), and interleukin-13 (IL-13) were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR (RT-qPCR) and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin (TSLP) and OX40 ligand (OX40L) in the nasal mucosa. ResultsCompared to the control group, total nasal symptom score in the model group significantly increased (P<0.01). HE staining revealed disrupted and adhered cilia, thickened basement membranes, and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE, IL-4, and IL-13, as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa, were significantly elevated in the model group (P<0.05 or P<0.01). Compared to the model group, the total nasal symptom scores in all drug intervention groups were significantly reduced; the serum total IgE levels in the loratadine group, the low- and medium-dose XD groups, and the low- and high-dose MDCP groups were significantly reduced; and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased (P<0.05 or P<0.01). Nasal mucosal structure was improved. Except for the low-dose MDCP group, all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa (P<0.01). All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L (P<0.05). The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA, and TSLP protein levels compared to the loratadine group (P<0.05). ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway, thereby attenuating Th2-mediated immune responses.
