ObjectiveTo evaluate the efficacy and possible mechanism of Wei's Huoxue Tongluo Formula （韦氏活血通络方，WHTF） in treating atrophic-stage non-arteritic anterior ischemic optic neuropathy （NAION） with qi deficiency and blood stasis. MethodsA total of 82 atrophic-stage NAION patients with qi deficiency and blood stasis were randomly divided into a treatment group and a control group， with 41 cases in each group. The treatment group was given oral administration of WHTF twice a day plus acupoint injection of distilled water 2 ml at Taiyang （EX-HN5） once daily， while the control group received injection of compound anisodine injection 2 ml at Taiyang （EX-HN5） once daily and oral administration of WHTF placebo twice a day. Both groups received treatment for a course of 14 days. The best-corrected visual acuity （BCVA）， optic disc perfusion density （PD）， flux index （FI）， macular superficial PD， vascular density （VD）， and traditional Chinese medicine （TCM） syndrome scores were compared between groups before treatment and on day 7 and day 14 of treatment. Additionally， mean defect （MD） and mean sensitivity （MS） of visual fields were measured before treatment and on day 14， along with safety evaluation. ResultsAfter treatment， both groups showed significant improvement in BCVA， visual field MD and MS， and TCM syndrome scores （P＜0.05 or P＜0.01）. On day 14 of treatment， the TCM syndrome score in the treatment group was significantly lower than that in the control group （P＜0.05）. There was no significant improvement in optic disc PD and FI， and macular superficial PD and VD after treatment in either group （P＞0.05） except that on day 7 the macular superficial foveal PD in the control group was significantly better than that in the treatment group （P＜0.05）. During the treatment period， no serious adverse events occurred in either group. ConclusionWHTF can improve the visual function indicators including visual acuity and visual field， as well as TCM syndrome scores in atrophic-stage NAION patients with qi deficiency and blood stasis. It shows clinical safety， although it does not appear to have a significant effect on optic disc or macular blood flow.

Objective: To explore the individual and joint effects of outdoor activities and different types of sedentary behavior on adolescent internalizing behaviors, so as to provide a basis for the prevention and intervention of such behaviors. Methods: From July to December 2023, a stratified cluster random sampling method was used to select 1 691 primary and secondary school students in grades 5-12 from four primary and secondary schools in Baise City. Anonymous surveys were conducted by using the Outdoor Activities Questionnaire,Adolescent Sedentary Activity Questionnaire, and Youth Self Report. The Chi square test and Logistic regression analyses were used for statistical analysis. Results: The detection rate of internalizing behavior among adolescents was 13.13%, and the detection rate of internalizing behaviors in girls (15.53%) was significantly higher than that in boys ( 10.77 %) ( χ 2=8.39, P <0.01). Logistic regression analysis showed that outdoor activities ≥1 h/d ( OR =0.56), screen based entertainment sedentary behavior < 2 h/d ( OR =0.58), and cultural sedentary behavior < 2 h/d ( OR =0.55) significantly reduced the risk of internalizing behaviors (all P <0.05). Logistic regression analysis of interaction effects revealed that the risks of internalizing behaviors were lower in the groups with "outdoor activities ≥1 h/d + screen based entertainment sedentary behavior <2 h/d" ( OR = 0.27) and "outdoor activities ≥1 h/d + cultural sedentary behavior <2 h/d" ( OR =0.30)(both P <0.01). Conclusions Outdoor activities can mitigate the adverse effects of sedentary behaviors on adolescents internalizing behaviors. Reducing screen time and leveraging the synergistic effects of "outdoor + cultural" activities may help reduce the risk of internalizing behaviors among primary and secondary school students.

Objective To introduce the application scene,operating steps and preliminary clinical effect of tibial bone mass preservation technique in medial unicompartmental knee arthroplasty(MUKA).Methods A total of 15 patients with antero-medial knee osteoarthritis(AMOA)treated in this hospital from May 2022 to May 2023 were selected as the study subjects.The tibial bone mass preservation technique was a-dopted to complete MUKA(fixed platform prosthesis).The operating time,intraoperative bleeding volume,hospitalization duration and operation complications were recorded.The VAS score before operation and in last follow up,range of motion(ROM)of knee joint,Knee Society Score(KSS),hip and knee stomping angle(HKA)of lower extremity in the operation side and image results were recorded to evaluate the clinical effect.Results The operations in 15 cases were successfully completed.The average operation time was(82.73±9.97)min,mean intraoperative bleeding volume was(21.00±9.49)mL and average hospital stay was(4.9±1.4)d.There was no intraoperative nerve,vascular and medial collateral ligament injury,no iatro-genic fracture,and no postoperative surgical site infection.All patients were followed up for average(5.87±2.77)months.The VAS score of knee joint,ROM,KSS and HKA angle of lower limb in the operated side were significantly improved compared with before operation(P<0.05).There was no prosthesis loosening,displacement or fragmentation,and no obvious degeneration aggravation of the lateral compartment of the knee joint.Conclusion The tibial bone mass preservation technique is a simple,effective and reliable method to deal with the slightly tight flexion space after tibial osteotomy during MUKA,and the postoperative clinical efficacy and imaging results are excellent.

Objective To investigate the status of management of iodinated contrast media(ICM)extravasation in Henan Province,as well as nurses' knowledge and influencing factors,in order to provide a basis for optimizing management strategies.Methods A self-designed questionnaire was applied,employing convenience sampling,to survey nursing administrators and nurses in the radiology departments of 55 tertiary hospitals across 16 regions of Henan Province,from December 2024 to January 2025.Multiple linear regression analysis was conducted to explore the factors influencing nurses' knowledge.Results A total of 55 nursing administrators and 64 nurses participated,with a valid questionnaire response rate of 100％.The survey results reveal that only 5.45％of radiology depart-ments utilized high-pressure central venous catheters,and 32.73％employed vascular visualization techniques.When setting the high-pressure injection speed for ICM,only 54.55％of radiology departments required an assessment of the type and model of intravenous access.Additionally,only 9.09％of radiology departments mandated an observa-tion for 2 to 4 hours following ICM extravasation.Furthermore,only 50.91％of radiology departments had estab-lished an information system for ICM use.The nurses' knowledge score regarding the prevention and management of ICM extravasation was(90.00±17.59),influenced by years of experience in radiology and professional titles(P＜0.05).Conclusion The prevention and management measures for ICM in radiology departments in Henan Province need further improvement.Nursing administrators should optimize management strategies,improve relevant training systems,and continuously enhance nurses' knowledge and practical abilities.

Objective:To review the diagnosis, treatment and quality of life of patients with primary immune thrombocytopenia (ITP) in seven medical centers in some areas of Hubei Province.Methods:A retrospective analysis was conducted on age, disease course, symptoms, diagnosis, and treatment status (including testing items, drug selection, and adverse reactions) of patients with ITP in seven medical centers in Hubei Province from January 2020 to December 2022. An online survey was conducted on the quality of life of patients using the ITP Patient Assessment Questionnaire (ITP-PAQ) .Results:Among the 1033 patients, those with newly diagnosed, persistent, and chronic ITP accounted for 39.8%, 19.1%, and 41.1%, respectively. Most patients exhibit varying degrees of bleeding. Regarding treatment, corticosteroids and thrombopoietin drugs are the most commonly chosen treatment drugs for ITP, and the adverse reactions to treatment mainly include diarrhea, liver dysfunction, and thrombosis. The ITP-PAQ survey of 125 patients revealed that ITP significantly impairs their life quality. Patients with ITP scored significantly lower in fatigue, sleep, fear, exercise, work, and social aspects.Conclusion:A relatively high proportion of patients with ITP progressed to the chronic phase. Corticosteroids and thrombopoietin drugs are the two main treatment drugs for ITP patients. The quality of life of patients with ITP is significantly reduced in multiple dimensions.

Objective:To analyze the values of platelet transforming growth factor-β (TGF-β) and SMAD family member 2 (Smad2) in patients′ peripheral platelets for CRC diagnosis and staging.Methods:Retrospective case-control study. Tumor tissues, paratumor tissues and peripheral blood samples were collected from 248 CRC patients (147 males, 101 females; age 21-93 years) diagnosed in the First Hospital of Jilin University from October 10th, 2020, to March 10th, 2025. Peripheral blood samples were also collected from 40 colorectal adenomatous polyp patients (21 males, 19 females; age 22-74 years) and 75 healthy individuals (43 males, 32 females; age 18-81 years) during the same period. Tissue homogenates and platelets were isolated using tissue disruption and gradient centrifugation, respectively. Total RNA was respectively extracted from tissues and platelets, and the expression levels of TGF-β and Smad2 were quantified by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) expressed as relative quantity 2 -ΔΔCt. Differences of TGF-β and Smad2 expression were compared between CRC tissues and adjacent tissues, as well as among CRC patients, polyp patients, and healthy controls. The relationship of platelet TGF-β and Smad2 expression with pathological features includingtumor stage, pathological type, and metastasis were analyzed. The efficiency of platelet TGF-β, Smad2, and their combination in diagnosing CRC was evaluated using receiver operating characteristic (ROC) curves. Results:The expression levels of TGF-β and Smad2 in CRC tumor tissues[1.09 (0.45, 2.00), 2.93 (0.78, 6.73)] were significantly higher than those in adjacent tissues[0.81 (0.27, 1.50), 1.29 (0.40, 2.63)] ( Z TGF-β=4.54, Z Smad2=6.67, both P<0.001). The expression levels of TGF-β and Smad2 in platelets of CRC patients[2.73(1.53, 4.38), 3.16 (1.58, 4.38)] were significantly higher than those in the colorectal polyp group[1.23(0.70, 2.54), 1.16(0.78, 2.27)] and the healthy control group[0.96(0.51, 1.88), 0.92 (0.55, 1.88)] ( H TGF-β=59.71, H Smad2=78.74, both P<0.001). Platelet TGF-β expression increased progressively with tumor stage (stage 1-4) ( P<0.05), while platelet Smad2 levels were higher in metastatic CRC compared with non-metastatic cases ( P<0.05). ROC curve analysis showed that the area under the curve (AUC) for diagnosing CRC when combining platelet TGF-β and Smad2 was 0.81[95%Confidence interval( CI) 0.77—0.86], which was 0.90 (95% CI 0.86—0.93) if adding serum carcinoembryonic antigen (CEA). Conclusion:Platelet TGF-β and Smad2 expression correlates with the diagnosis and staging of CRC, demonstrating potential as liquid biopsy biomarkers for colorectal malignancies.

Objective:To investigate the genetic causes of fetuses with abnormal nasal bone development in early pregnancy.Methods:A retrospective study was conducted which involved 422 cases of singleton pregnancies with nasal bone development abnormalities indicated by ultrasound screening at 11 to 13 weeks and 6 days of gestation, who underwent chorionic villus sampling for prenatal diagnosis at the Prenatal Diagnosis and Genetic Center, Maternity & Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2015 to May 2023. All cases underwent chromosomal karyotype analysis and single nucleotide polymorphism array (SNP-array) analysis. Based on whether other abnormal ultrasound indicators were present, the cases were divided into isolated (175 cases) and non-isolated groups (247 cases). The results of invasive prenatal diagnosis, distribution of chromosomal abnormalities, detection of copy number variation (CNV) in fetuses with nasal bone development abnormalities, the relationship between maternal age, number of abnormal ultrasound indicators and chromosomal abnormalities, and pregnancy outcomes were analyzed. Statistical analysis was performed using the Chi-square test (continuity correction Chi-square test or Fisher's exact test). Results:(1) Among the 422 cases, 262 cases (62.1%) showed no abnormalities with both detection techniques; 160 cases had abnormalities, including 145 cases (34.4%) had consistent abnormal results and types of abnormalies with the two techniques; two cases (0.5%) had chromosomal translocations detected by karyotype analysis but not by SNP-array analysis; 13 cases (3.1%) had no abnormalities detected by karyotype analysis but had abnormal SNP-array results. This study's overall detection rate of chromosomal abnormalities was 37.9% (160/422), with an additional detection rate of 4.7% (13/275) using SNP-array technology. (2) Among the 160 cases of chromosomal abnormalities, there were 140 cases of aneuploidy, 18 cases of CNV, and two cases of chromosomal translocation. The overall detection rate of chromosomal abnormalities and the detection of aneuploidy, and pathogenic CNV in the non-isolated group was higher than that in the isolated group [74.3% (130/175) vs. 12.1% (30/247), χ2=168.02; 68.0% (119/175) vs. 8.5% (21/247), χ2=163.56; 5.7% (10/175) vs. 0.8% (2/247), χ2=4.74; all P<0.05]. Eighteen cases of CNV were detected using SNP-array technology, including eight cases in the isolated group and ten cases in the non-isolated group. (3) The age of the 422 pregnant women was (33.1±5.4) years. In both isolated and non-isolated groups, the detection rate of chromosomal abnormalities was higher in women of advanced age (expected delivery age ≥35 years) than those not [isolated group: 20.0% (17/85) vs. 8.6% (14/162), χ2=6.55; non-isolated group: 82.1% (69/84) vs. 65.9% (60/91), χ2=5.92; both P=0.010]; regardless of maternal age, the detection rate of chromosomal abnormalities in the non-isolated group was significantly higher than that in the isolated group ( χ2 were 65.28 and 92.42, respectively, both P<0.001). (4) In the non-isolated group, the detection rates of chromosomal abnormalities were 69.0% (78/113) and 83.9% (52/62) when nasal bone abnormalities were combined with one or more other abnormal ultrasound indicators, respectively. When combined with increased nuchal translucency, the detection rate of fetal chromosomal abnormalities was 73.2% (71/97), higher than the detection rate when combined with other single indicators (7/16) ( χ2=5.57, P=0.020). (5) Among the 262 cases with negative karyotype analysis and SNP-array results, 241 cases (92.0%) resulted in live births, with a gestational age at delivery of 39 weeks (32-41 weeks); 12 cases (4.6%) resulted in induced labor, five cases (1.9%) resulted in miscarriage, and four cases (1.5%) were lost to follow-up. The live birth rate in the isolated group was higher than that in the non-isolated group [86.9% (213/245) vs. 20.2% (35/173), χ2=187.00, P<0.001]. Conclusions:Fetuses with nasal bone developmental abnormalities in early pregnancy have a higher detection rate of chromosomal abnormalities and CNV. Invasive prenatal diagnosis is recommended for cases of nasal bone developmental abnormalities in early pregnancy, whether isolated or non-isolated. When combined with other abnormal indicators, the genetic etiology of the fetus is more complex, and detailed genetic counseling should be provided to the patient.

Objective:To investigate the impact of Wenyang Ligong Decoction on pregnancy outcomes after transcervical resection of adhesions (TCRA) in patients with intrauterine adhesions (IUA).Methods:A retrospective cohort study was conducted to collect clinical data from 151 patients with IUA who underwent TCRA in the Reproductive Medicine Department of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine between January 2020 and January 2023. Patients were divided into a Traditional Chinese medicine (TCM) group (79 patients) and a control group (72 patients) based on whether they received Wenyang Ligong Decoction after TCRA. The TCM group received estrogen and progesterone sequential therapy post-surgery, combined with Wenyang Ligong Decoction for 2-3 menstrual cycles. The control only received sequential treatment with estrogen and progesterone.Pregnancy outcomes one year after surgery were compared between the two groups. After adjusting for confounding factors using multivariate Cox regression analysis, the effect of Wenyang Ligong Decoction on pregnancy outcomes after TCRA in patients with IUA was observed.Results:The live birth rate [54.43%　(43/79)], the ongoing pregnancy rate [56.96% (45/79)], and the clinical pregnancy rate [52.03% (49/79)] were higher in the TCM group than in the control [26.39% (19/72), P<0.001; 30.56% (22/72), P=0.001;37.50% (27/72), P=0.003], with statistically significant differences. There were no statistically significant differences in early abortion rate and late abortion rate between the TCM group and the control (all P>0.05). According to the stratified analysis by preparation methods, in the natural conception group, the live birth rate [60.78% (31/51)], the ongoing pregnancy rate [62.75% (32/51)], and the clinical pregnancy rate [68.63% (35/51)] in the TCM group were significantly higher than those in control group [21.43% (12/56), P<0.001; 26.79% (15/56), P<0.001; 33.93% (19/56), P<0.001]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the assisted reproductive technology group, there were no statistically significant differences in live birth rate, ongoing pregnancy rate, clinical pregnancy rate, early miscarriage rate, and late miscarriage rate between the two groups (all P>0.05). According to the stratified analysis by age, in the <35-year-old patients, the live birth rate [66.00% (33/50)], the ongoing pregnancy rate [70.00% (35/50)], and the clinical pregnancy rate [74.00% (37/50)] in the TCM group were significantly higher than those in control group [41.30% (19/46), P=0.015; 47.83% (22/46), P=0.027; 54.35% (25/46), P=0.044]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the ≥35-year-old patients, the live birth rate [34.48% (10/29)], the ongoing pregnancy rate [34.48% (10/29)], and the clinical pregnancy rate [41.38% (12/29)] in the TCM group were significantly higher than those in control group [0%, P=0.001; 0%, P=0.001; 7.69% (2/26), P=0.004]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05).Univariate Cox regression analysis showed that age, number of previous uterine cavity interventions, IUA score, degree of IUA, and endometrial thickness after TCRA were independent risk factors for live births, and age, IUA score, degree of IUA, intima thickness after TCRA, and treatment group were the influencing factors of persistent pregnancy (all P<0.05). After adjusting for confounding factors, multivariate Cox regression analysis showed that Wenyang Ligong Decoction significantly improved the live birth rate ( HR=3.19, 95% CI: 1.77-8.11, P=0.001) and the rate of continuous pregnancy ( HR=3.66, 95% CI: 1.80-7.48, P<0.001) in patients with IUA. Conclusion:Wenyang Ligong Decoction can significantly improve pregnancy outcomes after TCRA in patients with IUA.

Lacking therapeutic targets highlights the crucial roles of chemotherapy and radiotherapy in the clinical management of triple-negative breast cancer (TNBC). To relieve the side effects of the chemoradiotherapy combination regimen, we design and develop a self-assembled micelle nanosystem consisting of perfluorocarbon chain-modified cisplatin prodrug. By incorporating perfluorodecalin, this nanosystem can effectively carry ozone and promote irradiation-derived reactive oxygen species (ROS) production. By leveraging the perfluorocarbon sidechain, the nanosystem exhibits efficient internalization by TNBC cells and effectively escapes from lysosomal entrapment. Under X-ray irradiation, ozone-generated ROS disrupts the intracellular redox balance, thereby facilitating the release of cisplatin in a reduction-responsive manner mediated by reduced glutathione. Moreover, oxygen derived from ozone decomposition enhances the efficacy of radiotherapy by alleviating tumor hypoxia. Notably, the combination of irradiation with ozone-loaded cisplatin prodrug nano system synergistically prompts antitumor efficacy and reduces cellular/systemic toxicity in vitro and in vivo. Furthermore, the combo regimen remodels the tumor microenvironment into an immune-favored state by triggering immunogenic cell death and relieving hypoxia, which provides a promising foundation for a combination regimen of immunotherapy. In conclusion, our nanosystem presents a novel strategy for integrating chemotherapy and radiotherapy to optimize the efficacy and safety of TNBC clinical treatment.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.
