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.

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 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.

Objective To observe the value of diffusion-weighted imaging(DWI)parameters for evaluating grade of gliomas.Methods Totally 116 patients with glioma were retrospectively enrolled and divided into low-grade group(Ⅰ—Ⅱ,n=66)and high-grade group(Ⅲ—Ⅳ,n=50)according to 2000 WHO tumor grading criteria.Clinical and DWI data,including Ki-67 labeling index(LI),apparent diffusion coefficient(ADC),exponential ADC(EADC)and relative ADC(rADC)were compared between groups.The correlations of ADC,EADC and rADC with Ki-67 LI were explored,and the efficacy of above indexes for evaluating grade of glioma was analyzed.Results Significant differences of Ki-67 LI,ADC,EADC and rADC were found between groups(all P＜0.05).ADC and rADC of glioma were negatively correlated(r=-0.565,-0.625,both P＜0.05),while EADC was positively correlated with Ki-67 LI(r=0.587,P＜0.05).ADC,EADC,rADC and Ki-67 LI were all impact factors of grade of glioma(all P＜0.05),with the area under the curve of 0.768,0.802,0.788 and 0.793,respectively,and AUC of the combination of the four was 0.874,significantly higher than each index alone(all P＜0.05).Conclusion ADC,EADC and rADC were helpful for evaluating grade of glioma.Combining with Ki-67 LI could further improve diagnostic efficacy.

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 detect levels of plasma long non coding RNA(lncRNA)CCAAT enhancer binding protein alpha antisense 1(CEBPA-AS1)and microRNA-139-5p(miR-139-5p)in patients with acute cerebral infarction(ACI),and to explore their relationship with cognitive dysfunction in ACI patients.Methods A total of 132 ACI patients treated in our hospital were included for the study.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate the cognitive function of ACI patients,and they were diveded into the cognitive dysfunction group(n=63)and the normal cognitive function group(n=69).The general data of the two groups were compared.The qRT-PCR method was applied to measure plasma levels of lncRNA CEBPA-AS1 and miR-139-5p in ACI patients.Pearson method was applied to analyze the correlation between plasma lncRNA CEBPA-AS1 and miR-139-5p in ACI patients.Multivariate Logistic regression was applied to analyze factors influencing cognitive dysfunction in ACI patients.Receiver operating characteristic(ROC)curve was applied to evaluate the diagnostic value of plasma lncRNA CEBPA-AS1 and miR-139-5p for cognitive dysfunction in ACI patients.Results Compared with the normal cognitive function group,the plasma lncRNA CEBPA-AS1 was higher and the miR-139-5p was lower in the cognitive dysfunction group(P＜0.05).Correlation analysis showed that there was a negative correlation between lncRNA CEBPA-AS1 and miR-139-5p(r=-0.462,P＜0.01).Multivariate analysis showed that high school education or below,decreased plasma miR-139-5p,and increased lncRNA CEBPA-AS1 were risk factors for cognitive dysfunction in ACI patients(P＜0.05).The area under the curve(AUC)of lncRNA CEBPA-AS1 and miR-139-5p in the diagnosis of cognitive dysfunction in ACI patients was 0.865 and 0.798,respectively.The combined diagnostic efficacy of the two(AUC=0.912)was better than single index.Conclusion The plasma lncRNA CEBPA-AS1 is increased and the plasma miR-139-5p is decreased in patients with ACI combined with cognitive dysfunction,and both are influencing factors for cognitive dysfunction in ACI patients,and the combined diagnostic efficacy is high.

Objective:To construct a thyroid nodule segmentation model using ultrasound dynamic images and explore its potential for assisting in the screening of thyroid nodules.Methods:A total of 126 patients with thyroid nodules（comprising 150 nodules）who were diagnosed and treated at Xuzhou Cancer Hospital from April 2024 to December 2024 were prospectively enrolled. Two-dimensional ultrasound was performed to capture short-axis and long-axis video images of thyroid nodules，forming a dynamic ultrasound image dataset. The dataset was divided into training，validation，and test sets in a ratio of 6∶1∶3. After the training loss curve converged，the model that performed well on the validation set was selected for testing. Three-fold cross-validation was employed for training and testing. All 300 ultrasound videos were divided into three subsets. In each experiment，two subsets were used as the training set，and one subset was used as the test set to evaluate the model's generalization ability. A collaborative spatiotemporal diffusion model was established based on the dynamic trends and tissue texture details of thyroid nodules. Six widely used segmentation metrics were employed to evaluate the model's application capabilities.Results:The study included 126 patients with 150 thyroid nodules，300 dynamic ultrasound images，and video lengths of 3-4 seconds per nodule，resulting in 12 312 segmented images. The size of the thyroid nodules was（10.7 ± 10.6）mm（transverse diameter）×（8.4 ± 6.3）mm（anteroposterior diameter）. Among the nodules，62（41.3%）had clear boundaries，while 88（58.7%）had indistinct boundaries；61（40.7%）exhibited regular shapes，while 89（59.3%）were irregular；66（44.0%）had a taller-than-wide aspect ratio；and 70（46.7%）showed microcalcifications. The collaborative diffusion model based on dynamic ultrasound image segmentation achieved the following scores：a Jaccard score of（69.22 ± 0.03）%，a Dice score of（79.16 ± 0.18）%，a Precision score of（86.70 ± 0.17）%，a Recall score of（77.82 ± 0.04）%，an Sα score of（85.26 ± 0.01）%，and an Eθmn score of（90.58 ± 0.17）%. Compared to other models，this model demonstrated significant improvements across all evaluation metrics，achieving the highest values in each metric with increments of over 8% and 1%，respectively. Conclusions:The collaborative diffusion model with a dynamic controller，constructed based on dynamic ultrasound images of thyroid nodules，demonstrates excellent performance in ultrasound image segmentation. It improves the accuracy of thyroid nodule screening，thereby providing a valuable auxiliary diagnostic tool for clinical practice.

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.

Hemorrhagic shock is a common clinical emergency that can aggravate cell injury after resuscitation. Astrocytes are crucial for the survival of neurons because they regulate the surrounding ionic microenvironment of neurons. Although hemorrhagic shock and resuscitation (HSR) injury can impair cognition, it remains unclear how this insult directly affects astrocytes. In this study, we established an HSR model by bleeding and re-transfusion in mice. The social interaction test and new object recognition test were applied to evaluate post-operative cognitive changes, and the results suggest that mice experience cognitive impairment following exposure to HSR. In the HSR group, the power spectral density of β and γ oscillations decreased, and the coupling of the θ oscillation phase and γ oscillation amplitude was abnormal, which indicated abnormal neuronal oscillation and cognitive impairment after HSR exposure. In brief, cognitive impairment in mice is strongly correlated with Ca²⁺ signal strength in lateral septum astrocytes following HSR.
