Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

The aging microenvironment, as a key driver of tumorigenesis and progression, plays a critical role in tumor immune regulation through one of its core features-the senescence-associated secretory phenotype (SASP). SASP consists of a variety of interleukins, chemokines, proteases, and growth factors. It initially induces surrounding cells to enter a state of senescence through paracrine mechanisms, thereby creating a sustained inflammatory stimulus and signal amplification effect within the tissue microenvironment. Furthermore, these secreted factors activate key signaling pathways such as NF-κB, cGAS-STING, and mTOR, which regulate the expression of immune-related molecules (such as PD-L1) and promote the recruitment of immunosuppressive cells, including regulatory T cells and myeloid-derived suppressor cells. This process ultimately contributes to the formation of an immunosuppressive tumor microenvironment. Furthermore, the article explores potential anti-tumor immunotherapy strategies targeting SASP and its associated molecular mechanisms, including approaches to inhibit SASP secretion or eliminate senescent cells. Although these strategies have shown promise in certain tumor models, the high heterogeneity among tumor types may result in varied responses to SASP-targeted therapies. This highlights the need for further research into adaptive stratification and personalized treatment approaches. Targeting immune regulatory mechanisms in the aging microenvironment-particularly SASP-holds great potential for advancing future anti-tumor therapies.

ObjectiveTo investigate the potential mechanism of Liangxue Tuizi Formula (凉血退紫方, LXTZF) in treating Henoch-Schönlein Purpura (HSP) by examining its regulatory effect on neutrophil extracellular trap (NETs) dysregulation via the rapidly accelerated fibrosarcoma kinase (RAF)/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. MethodsSeventy Wistar rats were randomly allocated into a blank control group (n=14) and a modeling group (n=56). Rats in the modelling group underwent an eight-week modelling period to establish HSP rat models with blood-heat syndrome via modified ovalbumin (OVA) induction method combined with oral administration of heat-property Chinese herbal medicine. Fifty successfully modeled rats were subsequently randomly divided into five groups (n=10 per group), model group, compound glycyrrhizin group, LXTZF group, RAF inhibitor group, and LXTZF + RAF agonist group. Additionally, 10 rats were selected from the original blank control group for the final experiment. From the 11th week of modelling, rats in the blank control group and the model group received 1 ml/(100 g·d) ultrapure water via oral administration, in addition to 0.5 ml/(kg·d) 0.9% sodium chloride solution via intraperitoneal injection. The LXTZF group and the compound glycyrrhizin group received 7.5 g/(kg·d) LXTZF granule suspension via gavage, 13.5 mg/(kg·d) compound glycyrrhizin suspension via gavage, respectively. The RAF inhibitor group received 1 mg/(kg·d) GW5074 suspension via intraperitoneal injection and ultrapure water via oral administration; the LXTZF + RAF agonist group received 7.5 g/(kg·d) LXTZF granule suspension via gavage and 1 mg/(kg·d) paclitaxel suspension via intraperitoneal injection. All administrations were performed once daily for 4 weeks. After intervention, skin tissue histopathology was examined by hematoxylin and eosin (H&E) staining, immunoglobulin A (IgA) deposition was assessed via immunofluorescence, serum levels of neutrophil elastase (NE), tumor necrosis factor-α (TNF-α), and vascular cell adhesion molecule-1 (VCAM-1) were measured using enzyme-linked immunosorbent assay (ELISA), serum myeloperoxidase (MPO) level was determined by a colorimetric assay; the mRNA expression levels of RAF, MEK, and ERK in skin tissue were detected by real-time quantitative polymerase chain reaction (RT-qPCR); and the protein expression of RAF, MEK, ERK, as well as phosphorylated MEK (p-MEK) and phosphorylated ERK (p-ERK), were analyzed by Western Blot. ResultsSkin tissue in the blank control group rats remained normal, whereas the model group exhibited neutrophil infiltration and haemorrhage with red blood cell rupture. In all drug intervention groups, neutrophil infiltration and haemorrhagic exudation reduced markedly, with LXTZF group demonstrating the most pronounced improvement. Compared with the blank control group, rats in the model group exhibited enhanced IgA fluorescence intensity in skin tissue, elevated serum levels of NE, MPO, TNF-α and VCAM-1, increased mRNA expression of RAF, MEK, ERK1 and ERK2, as well as heightened RAF protein levels and p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with the model group, the drug intervention groups exhibited reduced IgA fluorescence intensity in skin tissue, along with decreased serum levels of NE, MPO, TNF-α, and VCAM-1 (P<0.05). In LXTZF group and RAF inhibition groups, reduced mRNA expression of RAF, MEK, ERK1, and ERK2 was observed in rat skin tissue, alongside decreased RAF protein levels and reduced p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with LXTZF + RAF agonist group, the compound glycyrrhizin group, LXTZF group, and RAF inhibitior group exhibited reduced IgA fluorescence intensity in skin tissue, decreased serum NE, MPO, TNF-α, and VCAM-1 levels, and decreased MEK mRNA expression and p-MEK/MEK ratio (P<0.05). ConclusionThe potential mechanism by which LXTZF treats Henoch-Schönlein purpura with blood heat syndrome may involve blocking the RAF/MEK/ERK signaling pathway in skin tissue, and suppressing excessive formation of NETs, thereby reducing IgA deposition in dermal microvessels and attenuating systemic inflammatory responses.

Objective:To observe the effects of electroacupuncture (EA) at acupoints of Shaoyang meridian on mechanical and thermal pain threshold, TRPV1, CGRP mRNA and TRPV1, p-TRPV1, CGRP protein expressions in TG of CM rats; To explore its mechanism.Methods:Totally 24 SD rats were divided into blank group, model group and EA group according to random number table method, with 8 rats in each group. The blank group did not do any treatment; the model group and the EA group were given intraperitoneal injection of nitroglycerin (10 mg/kg) on the 1st, 3rd, 5th, 7th and 9th day, once a day, for 5 times to prepare migraine rat model; after modeling, the model group was given binding and restraint for 30 min, and the EA group was given binding and restraint for 30 min treatment; the changes of basic mechanical and thermal pain thresholds of rats before and after modeling and intervention were observed, the mRNA expression levels of TRPV1 and CGRP in TG rats were detected by qPCR, and the protein expression levels of TRPV1, p-TRPV1 and CGRP in TG rats were detected by Western blot method.Results:After intervention, compared with the model group, the periorbital and plantar mechanical pain thresholds and plantar thermal pain thresholds in EA group increased ( P<0.05), the TRPV1 and CGRP mRNA expressions in trigeminal ganglion decreased ( P<0.01), the protein expressions of TRPV1, p-TRPV1 and CGRP decreased ( P<0.05). Conclusion:EA at acupoints of Shaoyang meridian can obviously increase the mechanical and thermal pain threshold and improve pain sensitization in CM rats. The mechanism would be related to down-regulating the expression levels of TRPV1 and CGRP mRNA and TRPV1, p-TRPV1 and CGRP protein in the TG of CM rats.

ObjectiveTo explore the possible mechanisms of electroacupuncture at Fengchi (GB 20), Waiguan (TE 5), and Yanglingquan (GB 34) in treating chronic migraine from the perspective of nociceptive sensitization. MethodsForty SPF-grade SD rats were randomly divided into blank group, model group, electroacupuncture group, electroacupuncture + agonist group, and inhibitor group, with 8 rats in each group. Except for the blank group, rats were injected intraperitoneally with nitroglycerin to establish a chronic migraine rat model. After successful modeling, the electroacupuncture group received electroacupuncture at bilateral "Fengchi" (GB 20), "Waiguan" (TE 5), and "Yanglingquan" (GB 34) for 30 minutes each session. The electroacupuncture + agonist group received the same electroacupuncture treatment and additional injection of protein kinase C (PKC) agonist Phorbol 12-myristate 13-acetate (1.0 ng/μl, 25 μl) via the infraorbital foramen. The inhibitor group received PKC inhibitor Chelerythrine Chloride (1.0 ng/μl, 10 μl) via the infraorbital foramen. The blank group, model group, and inhibitor group underwent restraint for 30 minutes without other interventions. All groups were continuously intervened for 5 days. After the intervention, the nociceptive thresholds (mechanical and thermal pain) of the periorbital area and hind paw were measured. The expression levels of transient receptor potential vanillic acid subtype 1 (TRPV1), phosphorylated TRPV1 (p-TRPV1), PKC proteins, Trpv1, Pkc mRNA, and the average fluorescence intensity of transient receptor potential vanillic acid subtype 1 (TRPV1) and PKC in the trigeminal ganglion were detected using Western Blot, real-time fluorescence quantitative PCR, and immunofluorescence methods. ResultsCompared with the blank group, the mechanical and thermal pain thresholds of the periorbital area and hind paw were reduced in the model group, and the protein levels of TRPV1, PKC, p-TRPV1, as well as the mRNA expression of Trpv1 and Pkc, and the average fluorescence intensity of TRPV1 and PKC in the trigeminal ganglion significantly increased (P<0.05 or P<0.01). Compared with the model group, the electroacupuncture group exhibited increased mechanical and thermal pain thresholds in the periorbital and hind paw areas, and decreased protein levels of TRPV1, PKC, p-TRPV1, mRNA expression of Trpv1 and Pkc, and average fluorescence intensity of TRPV1. In the electroacupuncture + agonist group, the average fluorescence intensity of TRPV1 in the trigeminal ganglion decreased. The inhibitor group exhibited increased mechanical pain thresholds in the periorbital area and thermal pain thresholds in the hind paw, along with decreased protein levels of TRPV1, PKC, p-TRPV1, and the average fluorescence intensity of TRPV1 and PKC (P<0.05 or P<0.01). Compared with the electroacupuncture group, the electroacupuncture + agonist group showed an increase in the protein levels of TRPV1, PKC, p-TRPV1, and the mRNA expression of Trpv1 (P<0.05 or P<0.01). ConclusionElectroacupuncture at the "Fengchi" (GB 20), "Waiguan" (TE 5), and "Yanglingquan" (GB 34) acupoints can increase the mechanical and thermal pain thresholds in chronic migraine rats and alleviate nociceptive sensitization. The mechanism may be related to the inhibition of PKC/TRPV1 pathway.

Objective:To compare the efficacy and safety of flow diverter (FD) implantation versus stent-assisted coil embolization (SACE) in unruptured saccular aneurysms located at distal segments of the Willis circle.Methods:A retrospective study was performed; 119 patients with unruptured saccular aneurysms located at distal segments of the Willis circle who received FD implantation or SACE in Department of Neurosurgery, Guangdong Provincial People's Hospital, Southern Medical University and Department of Cerebrovascular Surgery, Neurosurgery Center, Southern Medical University from January 2018 to May 2025 were selected. According to different surgical methods, they were divided into a FD group ( n=60) and a SACE group ( n=59). These patients were subjected to propensity score matching (PSM) using 1:1 nearest neighbor matching method to eliminate confounding factors such as gender, age, aneurysm location, and aneurysm diameter (maximum diameter); and then, differences in neurological functional prognosis (good prognosis: modified Rankin scale scores of 0-2), complete aneurysm occlusion rate (O'Kelly-Marotta grade D or Raymond occlusion classification class I), and overall (perioperative and follow-up) complications were compared between the two groups. Results:After PSM, there were 43 patients in both FD group and SACE group. No significant difference was found in clinical and imaging follow-ups (12[6, 19] months vs. 10[6, 15] months, 10[5, 19] months vs. 9[2, 15] months) between the FD group and SACE group ( P>0.05). At the last imaging follow-up, the complete aneurysm occlusion rate in the FD group (65.1%[28/43]) was significantly lower than that in the SACE group (76.7%[33/43], P<0.05). At the last clinical follow-up, no significant difference was noted in good prognosis rate (95.3%[41/43] vs. 97.7%[42/43]) and overall complication rate (30.2%[13/43] vs. 18.6%[8/43]) between the FD group and SACE group ( P>0.05). Conclusion:Both FD implantation and SACE are safe and effective for unruptured saccular aneurysms located at distal segments of the Willis circle; the complete aneurysm occlusion rate within 1 year of FD implantation is relatively low.
