This paper intend to study the following critical fractional Schrödinger-Kirchhoff-Poisson equations with electromagnetic fields in R3{{\mathbb{R}}}^{3}: ε2sM([u]s,A2)(−Δ)Asu+V(x)u+(∣x∣2t−3∗∣u∣2)u=f(x,∣u∣2)u+∣u∣2s∗−2u,x∈R3.{\varepsilon }^{2s}{\mathfrak{M}}\left({\left[u]}_{s,A}^{2}){\left(-\Delta )}_{A}^{s}u+V\left(x)u+\left(| x\hspace{-0.25em}{| }^{2t-3}\ast | u\hspace{-0.25em}{| }^{2})u=f\left(x,| u\hspace{-0.25em}{| }^{2})u+| u\hspace{-0.25em}{| }^{{2}_{s}^{\ast }-2}u,\hspace{1em}x\in {{\mathbb{R}}}^{3}. Under suitable assumptions, together with the concentration compactness principle and variational method, we prove that the existence and multiplicity of semiclassical solutions for above problem as ε→0\varepsilon \to 0.

The eastern Tianshan-Beishan area is one of the important metallogenic belts in China, but the Late Permian-Middle Triassic tectonic evolution still remains a controversial issue. The Guobaoshan area is located in the eastern section of the eastern Tianshan mountains. Five kinds of Late Permian-Middle Triassic granitoids are exposed in this area, namely granodiorite, monzonitic granite, quartz syenite, syenogranite and amazonite granite. These granitoids are generally rich in silicon and alkali. Granodiorite, monzonitic granite and quartz syenite are characterized by the enrichment of potassium and magnesium, showing LREE enriched REE patterns (LREE/HREE=0.86) with weakly negative Eu anomaly, while syenogranite, being similar to sodic and ferrous amazonite granite, is characterized by a "sea-gull" REE pattern and significant negative Eu anomaly (δEu=0.03), as well as enrichment of Ta and Rb. The 206Pb/238U surface ages of zircons of granodiorite are concentrated in the range of 255~250 Ma, which are earlier than that of amazonite granite. Both syenogranite and amazonite are typical A-type granite and formed in intra-plate environment, but the other granitoids are Ⅰ-type granite and formed in post-collision tectonic setting. There is no genetic relation between two groups of granitoids and they belong to different magma series. The Guobaoshan area was still in the post-collision tectonic setting during 255~250 Ma, and switched to the intra-plate environment before 247 Ma.

Objective: Total hip arthroplasty (THA) effectively treats end‐stage hemophilic hip arthropathy. Given hemophilia's unique characteristics, perioperative bleeding remains a significant risk for patients undergoing THA. Tranexamic acid (TXA), an efficient antifibrinolytic agent, may benefit the outcomes of THA for patients with hemophilia (PWH). This study aims to explore the clinical efficacy of intra‐articular injection of TXA in treating perioperative bleeding in PWH and assess its additional clinical benefits. Methods: The retrospective study comprised data of PWH who received THA from January 2015 to December 2021 in the research center. A total of 59 individuals were included in the study, divided into a TXA group (n = 31) and a non‐TXA group (n = 28). We compared various parameters, including total blood loss (TBL), visible blood loss (VBL), occult blood loss (OBL), intraoperative coagulation factor VIII (FVIII) consumption, perioperative total FVIII consumption, hemoglobin (HB), erythrocyte sedimentation rate (ESR), C‐reactive protein (CRP), length of hospital stay, hospitalization costs, length of surgery, total protein, activated partial thromboplastin time (APTT), D‐dimer, rate of joint swelling, hip joint range of motion (ROM), visual analogue scale (VAS), and Harris hip joint function scale (HHS) between the two groups. Follow‐up assessments were conducted for up to 24 months. A Student's t test was utilized for the statistical analysis. Results: This study demonstrated that intra‐articular TXA effectively reduced TBL (1248.19 ± 439.88 mL, p < 0.001), VBL (490.32 ± 344.34 mL, p = 0.003), and OBL (757.87 ± 381.48 mL, p = 0.004) in PWH who underwent THA. TXA demonstrated effectiveness in reducing VAS scores on POD1, POD7, and POD14 and joint swelling rates on POD1, POD7, POD14, and at discharge (p < 0.05). Additionally, the TXA group achieved higher HHS ratings at all follow‐up time points (p < 0.05), showing superior hip joint mobility, lower postoperative inflammation levels, reduced factor VIII consumption during surgery, and less postoperative nutritional loss. No statistically significant differences were observed between the two groups in terms of hospital stay, hospitalization costs, surgery duration, and coagulation indicators. Conclusion: Intra‐articular injection of TXA reduces perioperative bleeding in PWH undergoing THA while also improving joint mobility, post‐operative rehabilitation, and quality of life. This may provide value for the future application of TXA in PWH. [ABSTRACT FROM AUTHOR]
