Traditional Chinese medicine and its bioactive components have garnered increasing attention as potential therapeutic options for allergic asthma. By targeting the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, these natural compounds exhibit unique advantages in multilevel immunomodulation and inflammation suppression compared with single-target synthetic drugs. Accumulating pharmacological evidence supports their capacity to restore pathway homeostasis, positioning them as promising candidates for complementary strategies in asthma management. Allergic asthma, a heterogeneous respiratory disorder affecting approximately 150 million individuals worldwide, arises from a complex interplay of genetic predisposition, environmental exposures, and lifestyle factors. Its pathological progression is marked by aberrant activation of the PI3K/AKT signaling cascade, with the mechanistic target of rapamycin serving as a key downstream regulatory node. This evolutionarily conserved pathway orchestrates fundamental cellular processes that contribute to three hallmark pathological features of allergic asthma: chronic airway inflammation, structural remodeling of the bronchial architecture, and airway hyperresponsiveness. This review has 3 primary objectives: (1) to evaluate the role of the PI3K/AKT pathway in allergic asthma pathogenesis, (2) to analyze the molecular mechanisms of representative traditional Chinese medicine preparations and their active ingredients, and (3) to identify novel bioactive inhibitors derived from natural products. Collectively, these investigations provide a conceptual framework for the development of next-generation targeted therapies and for optimizing clinical management strategies for allergic asthma.

Objective Exploring genetic differences among geographic strains of Anopheles sinensis in China. Methods Based on the mitochondrial cytochrome oxidase subunit I(COⅠ )and ribosomal the second internal transcribed spacer(ITS2), genetic distance analyses were conducted on An. sinensis samples collected nationwide. Results Genetic differentiation was observed within An. sinensis geographic strains, primarily reflected in the genetic distances of COⅠ sequences, with some distances between samples exceeding those between closely related species. However, ITS2 sequences showed relatively low levels of differentiation within geographic strains. No significant separation was observed, and gene exchange exhibited a random pattern among geographic strains. Conclusions Significant differences in genetic distance were observed among An. sinensis samples, along with evidence of interspecific continuity among sibling species. For the identification of closely related species using wild-collected Anopheles mosquitoes samples, reliance solely on commonly used barcodes such as COⅠ and ITS2 may be insufficient. Additional molecular markers, including COⅡ and D3 gene fragments, should also be considered. Caution should be exercised when using COⅠ genes to identify cryptic species, especially within Anopheles mosquitoes.

OBJECTIVE To investigate the clinical characteristics of euglycemic diabetic ketoacidosis （euDKA） induced by empagliflozin， and provide references for safe medication. METHODS Case reports of euDKA induced by empagliflozin were retrieved and analyzed from PubMed， Web of Science， CNKI， and Wanfang Data. The Naranjo’s scale was adopted to assess the causal relationship between empagliflozin and euDKA. RESULTS A total of 29 patients were enrolled， including 16 males and 13 females，with a median age of 58 years. All patients were diagnosed with type 2 diabetes mellitus； 22 patients had at least one comorbidity. The median time to euDKA onset was 60 days after administration， and 7 cases occurred within 2 weeks of treatment. Perioperative periods，fasting，and low-carbohydrate or ketogenic diets were the main predisposing factors. Common presentations included nausea，vomiting， fatigue， tachypnea，and tachycardia. The causal relationship between empagliflozin and euDKA was assessed as “probable” in all cases. According to adverse reaction severity grading， 13 cases were grade 3 （severe） and 16 cases were grade 4 （life-threatening）. All patients discontinued empagliflozin and recovered after corresponding treatment. CONCLUSIONS euDKA is a serious adverse reaction to empagliflozin， which mostly occurs early in treatment. Perioperative periods， fasting， and ketogenic diets are prone to induce euDKA. Elderly patients and those with comorbidities are at higher risk. Risk assessment should be conducted before clinical administration； blood ketones and acid-base monitoring should be strengthened in the early medication period； withhold the drug before elective surgery， avoid prolonged fasting；upon diagnosis， discontinue empagliflozin and initiate intravenous insulin， provide fluid resuscitation promptly， and use other treatments to improve patient prognosis.

This study aimed to explore the mechanisms and molecular targets of total flavones of Abelmoschus manihot(TFA) plus empagliflozin(EM) in attenuating diabetic tubulopathy(DT) by targeting mitochondrial homeostasis and pyroptosis-apoptosis-necroptosis(PANoptosis). In the in vivo study, the authors established the DT rat models through a combination of uninephrectomy, administration of streptozotocin via intraperitoneal injections, and exposure to a high-fat diet. Following modeling successfully, the DT rat models received either TFA, EM, TFA+EM, or saline(as a vehicle) by gavage for eight weeks, respectively. In the in vitro study, the authors subjected the NRK52E cells with or without knock-down Z-DNA binding protein 1(ZBP1) to a high-glucose(HG) environment and various treatments including TFA, EM, and TFA+EM. In the in vivo and in vitro studies, The authors investigated the relative characteristics of renal tubular injury and renal tubular epithelial cells damage induced by reactive oxygen species(ROS), analyzed the relative characteristics of renal tubular PANoptosis and ZBP1-mediatted PANoptosis in renal tubular epithelial cells, and compared the relative characteristics of the protein expression levels of marked molecules of mitochondrial fission in the kidneys and mitochondrial homeostasis in renal tubular epithelial cells, respectively. Furthermore, in the network pharmacology study, the authors predicted and screened targets of TFA and EM using HERB and SwissTargetPrediction databases; The screened chemical constituents and targets of TFA and EM were constructed the relative network using Cytoscape 3.7.2 network graphics software; The relative targets of DT were integrated using OMIM and GeneCards databases; The intersecting targets of TFA, EM, and DT were enriched and analyzed signaling pathways by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG) software using DAVID database. In vivo study results showed that TFA+EM could improve renal tubular injury, the protein expression levels and characteristics of key signaling molecules in PANoptosis pathway in the kidneys, and the protein expression levels of marked molecules of mitochondrial fission in the kidneys. And that, the ameliorative effects in vivo of TFA+EM were both superior to TFA or EM. Network pharmacology study results showed that TFA+EM treated DT by regulating the PANoptosis signaling pathway. In vitro study results showed that TFA+EM could improve ROS-induced cell injury, ZBP1-mediatted PANoptosis, and mitochondrial homeostasis in renal tubular epithelial cells under a state of HG, including the protein expression levels of marked molecules of mitochondrial fission, mitochondrial ultrastructure, and membrane potential level. And that, the ameliorative effects in vitro of TFA+EM were both superior to TFA or EM. More importantly, using the NRK52E cells with knock-down ZBP1, the authors found that, indeed, ZBP1 was mediated PANoptosis in renal tubular epithelial cells as an upstream factor. In addition, TFA+EM could regulate the protein expression levels of marked signaling molecules of PANoptosis by targeting ZBP1. In summary, this study clarified that TFA+EM, different from TFA or EM, could attenuate DT with multiple targets by ameliorating mitochondrial homeostasis and inhibiting ZBP1-mediated PANoptosis. These findings provide the clear pharmacological evidence for the clinical treatment of DT with a novel strategy of TFA+EM, which is named "coordinated traditional Chinese and western medicine".

OBJECTIVE: To investigate the management strategies of external fixation combined with microsurgical techniques for repairing complex foot and ankle wounds in children. METHODS: The clinical data of 9 children with complex foot and ankle wounds who met the selection criteria between June 2017 and December 2021 was retrospectively analyzed. There were 6 boys and 3 girls, aged 3-13 years, with an average of 7.4 years. The causes of injury included crush injury in 5 cases and traffic accident injury in 4 cases. The wound size ranged from 6 cm×5 cm to 25 cm×18 cm. The time from injury to surgery ranged from 3 to 8 hours, with an average of 5 hours. All cases underwent staged surgical treatment. Among the 3 cases requiring deformity correction, 2 cases initially underwent free anterolateral thigh flap transplantation for wound coverage and limb salvage, followed by circular external fixation combined with osteotomy to address postoperative limb deformity, while 1 case received osteotomy for tibial fracture realignment prior to local pedicled flap reconstruction. All the 6 cases with non-deformity correction underwent initial external fixation followed by secondary flap reconstruction for wound management. The American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score was used to evaluate the foot and ankle function of children. RESULTS: All children successfully achieved limb salvage postoperatively. Among the 6 non-deformity correction cases, all flaps survived with satisfactory wound healing and no infection was observed; fractures healed within 2.5-4.5 months, after which external fixators were removed for functional rehabilitation with favorable recovery. One case treated with circular external fixation combined with osteotomy achieved bone union at 4 months postoperatively, followed by fixator removal. One case undergoing osteotomy for tibial fracture realignment showed bone healing at 2.5 months post-correction, with subsequent fixator removal. One patient receiving bone lengthening developed infection at 1 week postoperatively, which was managed with multiple debridements, ultimately achieving bone union at 16 months postoperatively and followed by fixator removal. At last follow-up, all patients demonstrated satisfactory ankle-hindfoot functional recovery, with AOFAS ankle-hindfoot scores ranging from 80 to 90 (mean, 84.2). CONCLUSION The combination of external fixation and microsurgical techniques demonstrates significant advantages in reconstructing complex foot and ankle wounds in children. The synergistic interaction provides both mechanical stability and biological repair, enabling early functional rehabilitation while reducing infection risks.

Objective:To evaluate spinal-pelvic mobility and sagittal spinal-pelvic alignment characteristics in patients with developmental dysplasia of the hip (DDH), and to investigate differences in sagittal spinal-pelvic parameters between patients with DDH and those with osteonecrosis of the femoral head (ONFH).Methods:A total of 55 patients with DDH who underwent primary total hip arthroplasty (THA) at the Affiliated Hospital of Xuzhou Medical University between April 2021 and March 2024 were retrospectively analyzed. The cohort included 8 males and 47 females, with a mean age of 56.16±10.82 years (range: 26-76 years). Among them, 18 patients had bilateral DDH and 37 had unilateral DDH. Fifty-five age- and sex-matched patients with ONFH were selected as the control group. Unilateral DDH cases were classified according to the Hartofilakidis classification: 18 cases of type A, 13 cases of type B, and 6 cases of type C. Lateral spinal-pelvic radiographs were used to measure pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and lumbar lordosis (LL) in both standing and sitting positions. Changes in sagittal spinal-pelvic parameters between standing and sitting positions were analyzed to assess spinal-pelvic mobility. Spinal-pelvic mobility was considered abnormal if △SS was outside the range of 10°-30°. Abnormal mobility was further categorized as stiffness (△SS<10°) or hypermobility (△SS>30°).Results:The PI (52.37°±12.43°), standing PT (12.13°±9.50°), and sitting PT (36.49°±13.43°) of DDH patients were significantly higher than those of ONFH patients (44.88°±11.38°, 7.80°±11.36°, and 28.91°±11.38°, respectively), with statistically significant differences ( P<0.05). Abnormal spinal-pelvic mobility, including both stiffness and hypermobility, was observed in 53% of DDH patients, with stiffness accounting for 20%. These proportions were significantly higher than those in ONFH patients, which were 24% and 6%, respectively ( P<0.05). The prevalence of abnormal spinal-pelvic mobility in Hartofilakidis type C DDH patients was 83%, significantly higher than the 30.8% observed in type B patients (χ 2=4.550, P=0.033). The standing LL (54.37°±11.59°) and sitting LL (28.56°±15.51°) in unilateral DDH patients were significantly greater than those in bilateral DDH patients (46.88°±15.30° and 20.42°±9.77°, respectively), with statistically significant differences ( P< 0.05). Conclusions:Compared with patients with ONFH, those with DDH demonstrate a higher prevalence of abnormal spinal-pelvic mobility, particularly a greater incidence of spinal stiffness. Among DDH subtypes, Hartofilakidis type C patients exhibit a higher proportion of abnormal mobility compared to types A and B. Additionally, patients with unilateral DDH present with greater lumbar lordosis than those with bilateral involvement.

Objective:To evaluate the feasibility and outcomes of transnasal endoscopic clipping of the paraclival internal carotid artery (ICA) in skull base surgery.Methods:The paraclival ICA was anatomically dissected in cadaveric head specimens. The clinical data of 15 patients with skull base lesions involving the ICA who admitted to the Department of Otorhinolaryngology Head and Neck Surgery at Tianjin Huanhu Hospital from January 2021 to December 2023 were retrospectively analyzed. Among them, 4 patients underwent transnasal endoscopic clipping of the paraclival ICA and concurrent lesion resection. The surgical methods were summarized, and the key points and indications of this technique were analyzed.Results:Intraoperative clipping of the ICA was successful and hemostatic in all 4 patients. Postoperatively, 3 patients had no complications, while 1 patient developed delayed ischemic cerebral infarction. Two patients were cured, 1 patient was maintained on immunotherapy, and 1 patient died. During follow-up, the clip was in situ in 1 patient, had detached in another, and was obscured by temporal muscle coverage in the remaining 2 patients.Conclusions:Transnasal endoscopic clipping of the paraclival ICA represents a potential option for managing the ICA in skull base surgery. However, it carries significant risks and limitations, mandating careful patient selection based on specific circumstances.
