Hepatocellular carcinoma(HCC)expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming.Aldolase A(ALDOA)plays a prominent role in glycolysis;however,little is known about its role in HCC development.In the present study,we aim to explore how ALDOA is involved in HCC proliferation.HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout,which is consistent with ALDOA overexpression encouraging HCC prolifera-tion.Mechanistically,ALDOA knockout partially limits the glycolytic flux in HCC cells.Meanwhile,ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase;ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function.A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun,and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells.In HCC patients,the expression level of ALDOA was correlated with the phosphorylation level of c-Jun(Thr93)and poor prognosis.Remarkably,hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models,and the knockdown of Aldoa strikingly decreased HCC development in vivo.Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription,opening additional avenues for anti-cancer therapies.

Objective:To analyze the clinical features of patients with traumatic optic neuropathy (TON) and to explore its clinical patterns and treatment outcomes.Methods:A retrospective analysis was conducted on data from 323 patients (334 eyes) with TON, who were treated in the Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University from April 1999 to October 2024. Among these patients, 288 were male and 35 were female, with ages ranging from 4 to 70 years. All patients were followed up for a period of 6 to 24 months, with the final follow-up visual acuity recorded as the ultimate visual outcome. The visual acuity evaluation criteria were classified into five levels: no light perception, light perception, hand movement in front of the eye, counting fingers at 1 meter, and "chart-visible acuity". A treatment outcome was deemed effective if the post-treatment visual acuity improved by one level or more compared to pre-treatment, or if the chart-visible acuity improved by two lines or more on the logMAR chart. The clinical characteristics of patients, causes of injury, complications, treatment methods, and changes in visual acuity before and after treatment were summarized. Logistic regression analyses were performed to identify the influencing factors affecting treatment efficacy.Results:TON occurred mostly in young (215/323, 66.56%) males (288/323, 89.16%), the majority of patients came from villages and towns (236/323, 73.07%). Traffic accidents (232/323, 71.83%) remained the main etiology. Most patients had craniofacial injuries and other bodily injuries. The effective rate of vision improvement was 50.30% (168/334). Multiple logistic regression analyses identified that residual vision (light perception or better) at presentation ( OR=3.26, P<0.001) and receiving treatment within 7 days after injury ( OR=2.04, P=0.008) were protective factors on visual acuity recovery, while the presence of orbital wall fracture was a risk factor for visual acuity recovery ( OR=0.26, P<0.001). Additionally, undergoing surgical treatment was a protective factor for visual improvement in patients with no light perception ( OR=2.94, P=0.007). For patients with residual vision at presentation, orbital wall fracture was a significant risk factor ( OR=0.28, P=0.009). Conclusions:TON is more prevalent in young males and is primarily caused by traffic accidents, leading to a poor prognosis. Timely medical intervention following injury significantly influences prognostic outcomes. Early surgical intervention (within 7 days) is recommended, particularly for patients with no light perception at presentation.

Objective To develop a risk prediction model for ischemic stroke in symptomatic intracranial atherosclerotic stenosis(ICAS)patients based on high-resolution magnetic resonance imaging(HR-MRI)and arterial spin labeling(ASL)imaging.Methods A total of 142 patients were included and divided into acute ischemic stroke(AIS)and transient ischemic attack(TIA)groups based on stroke occurrence.Clinical risk factors,plaque characteristics,and arterial transit artifact(ATA)presence on ASL images were compared between the two groups.Multivariate logistic regression analysis was performed,incorporating clinical risk factors,plaque characteristics,and double post labeling delay(PLD)ATA presence.The predictive value of different models was compared using receiver operating characteristic(ROC)curve and DeLong tests.Results Hypertension,positive lumen remodeling,plaque enhance-ment rate,1.5 s-ATA presence,and 2.5 s-ATA presence were independent risk factors for AIS(P＜0.05).The combination of HR-MRI and ASL imaging predicted AIS most effectively[area under the curve(AUC)=0.908;95％ confidence interval(CI)0.862-0.954].No significant difference was found between the prediction performances of HR-MRI and ASL(95％CI-0.041-0.082,Z=0.659,P=0.509).Conclusion ASL is more convenient than HR-MRI for predicting ischemic stroke in ICAS patients.A model combining plaque characteristics and ATA presence effectively predicts AIS occurrence.

OBJECTIVE To analyze the risk factors for excessive microbial contamination level tested for repaired endoscopes before reuse and to formulate targeted management strategies,providing a reference for handling such events.METHODS A total of 54 repaired endoscopes reused in the Digestive Endoscopy Room of a hospital in Shanxi Province from Oct.2021 to Jun.2024,with a total of 105 repairs,were selected as the study subjects.Mi-crobial contamination levels were tested for all repaired endoscopes before reuse,and they were divided into a posi-tive group(colony count＞20 CFU/item)and a negative group(colony count ≤20 CFU/item)based on the test results.The risk factors for excessive microbial contamination levels of repaired endoscopes before reuse were summarized.The positive rates of microbial contamination level tests for repaired endoscopes before reuse were compared between the pre-intervention period(from Oct.2021 to Jun.2024)and the post-intervention period(from Jul.2024 to Dec.2024).RESULTS The results of microbial contamination level tests of endoscopes with 105 repairs before reuse showed a positive rate of 27.62％(29/105).Shortening duration between cleaning and disin-fection before and after repair(OR=0.285)was a protective factor,scratches/grooves/leak repairs in the endo-scope tubes(OR=3.211),improper cleaning and disinfection(OR=5.257)and the less number of enzymatic brushing washes(OR=2.438)were identified as risk factors for excessive microbial contamination levels of re-paired endoscopes before reuse(P＜0.05).Before the intervention,the positive rate of microbial contamination level tests for repaired endoscopes was higher than that for non-repaired endoscopes(27.62％vs.3.45％,P＜0.001).After the intervention,there was no statistically significant difference in the positive rate of microbial con-tamination level tests between repaired and non-repaired endoscopes(5.26％vs.4.17％,P=0.681),but the posi-tive rate for repaired endoscopes was lower than that before the intervention(5.26％vs.27.62％,P=0.004).CONCLUSIONS The occurrence of excessive microbial contamination levels of repaired endoscopes before reuse frequemly occur.Formulating and implementing targeted management strategies may guarantee the qualified rate of cleaning and disinfection of endoscopes before the reuse,and enhance the safety for the reuse of repaired endoscopes.

Objective:To investigate the effectiveness and safety of lacosamide (LCM) in pregnant women with epilepsy.Methods:A retrospective study was conducted involving 6 pregnant women with epilepsy who were treated with LCM at the Electroencephalogram Monitoring Center of the Department of Neurology, Xijing Hospital of Air Force Military Medical University from January 2022 to June 2023. Their electroclinical characteristics, seizures during pregnancy, breastfeeding, and follow-up were summarized.Results:The 6 patients were aged 22 to 30 years at the time of pregnancy. Three patients were treated with monotherapy, with a daily dose of LCM ranging from 150 mg to 200 mg, while the other 3 patients were treated with combination therapy, with a daily dose of 150 mg. The seizures of 5 patients decreased during pregnancy compared with progestation except for the case 2 without adherence to Medication. No malformations were observed in the newborns, with the Apgar scores of 9-10 at 1 minute and 5 minutes after birth. The infants showed normal growth, development, intelligence, and motor skills in subsequent assessments. Two patients breastfed their infants, 1 for 6 months and the other for 14 months by the last follow-up, with a daily LCM dose of 150 mg to 300 mg during the breastfeeding. No adverse reactions were observed in the infants.Conclusion:The addition of LCM during pregnancy and lactation showed good effectiveness and safety, with no observed birth malformations.

Objective:To explore the feasibility of using a simplified multiple sleep latency test (MSLT) for the diagnosis of narcolepsy type 1.Methods:Data from 158 patients with narcolepsy type 1 and 58 patients with non-type 1 narcolepsy who underwent overnight video-polysomnography (V-PSG) and MSLT in the Sleep Center, Department of Neurology, Xijing Hospital, Air Force Military Medical University from March 2019 to April 2024 were retrospectively collected. By reducing the number of naps in the MSLT, the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT was evaluated using the receiver operating characteristic (ROC) curve. The DeLong test was used to compare whether there was a statistically significant difference between the simplified MSLT and the standard 5-nap MSLT. Cohen′s Kappa statistical analysis was performed to compare the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT.Results:The age of the 216 patients who were ultimately enrolled was 17 (13, 30) years, including 152 male patients (70.4%). The Cohen′s Kappa between the simplified 3-nap MSLT and the standard 5-nap MSLT was 0.875, which was 0.903 between the simplified 4-nap MSLT and the standard 5-nap MSLT (Bonferroni-corrected, both P0.001), indicating high and statistically significant agreement for both simplified protocols with the standard test. However, the DeLong test revealed that the area under the curve of the standard 5-nap MSLT (0.900, 95% CI 0.863-0.938) differed significantly from that of the simplified 3-nap MSLT (0.860, 95% CI 0.817-0.904; P0.05), whereas no significant difference was observed between the standard 5-nap MSLT and the simplified 4-nap MSLT (0.876, 95% CI 0.834-0.918; P0.05). Consequently, performing only the first 4 naps was sufficient for diagnosing narcolepsy type 1. Conclusion:The simplified 4-nap MSLT, specifically the first to fourth naps, may be used for the diagnosis of narcolepsy type 1.

Objective:To investigate and explore the expressional condition and therapeutic role of PD-1 and CD161 in the peripheral blood of patients treated with PEG-IFN-α for chronic hepatitis B (CHB), and their correlation with the degree of decrease in hepatitis B surface antigen (HBsAg).Methods:A retrospective cohort study was conducted. CHB patients who visited the Second Affiliated Hospital of Xi'an Jiaotong University from July 2022 to December 2023 and healthy controls during the same period were included. Peripheral blood samples were collected from the IFN treatment group (31 cases), the non-IFN treatment group (30 cases), and the healthy control group (30 cases). Flow cytometry was used to detect the CD8, + PD-1, + CD161 + T lymphocytes and their subpopulations among the three groups. The proportions of cellular subpopulations were compared to analyze intergroup differences using Kruskal-Wallis and Mann-Whitney U tests. The patients in the IFN treatment group were divided into two subgroups, high-and low-level, according to the median levels of PD-1 + lymphocytes, CD8 +PD-1 +T cells, and CD161 + lymphocytes. The magnitude of HBsAg decline was compared between the two groups. Results:The proportions of PD-1 + lymphocytes and CD8 +PD-1 +T cells in the IFN treatment group were significantly higher than those in the healthy control group and the non-IFN treatment group ( P<0.001). Moreover, the proportions of PD-1 + lymphocytes [IFN treatment group 48 weeks: 24.3 (23.7, 28.0)%, non-IFN treatment group: 12.7 (10.0, 18.5)%, P<0.01] and CD8 +PD-1 +T cells [IFN treatment group 48 weeks: 29.29 (26.73, 32.98)%, non-IFN treatment group: 17.69 (9.62, 20.68)%, P<0.05] were higher in the IFN treatment group than those in the non-IFN treatment group at 48 weeks. The proportion of CD8 +CD161 +T cells was significantly lower in patients treated with IFN than in the non-IFN treatment group ( P<0.05) at 24 and 48 weeks, with no statistically significant difference with the healthy control group ( P>0.05). In the IFN treatment group, patients with high levels of PD-1 + and CD8 + PD1 lymphocytes had a significantly lower HBsAg decline compared to low-level patients, whereas no significant correlation was found between CD161 levels and HBsAg decline [PD-1 + lymphocytes: 0.15 (0.02, 0.18) log 10 IU/mL vs. 0.32 (0.13, 0.42) log 10 IU/mL, P<0.01; CD8 +PD-1 +T cells: 0.16 (0.03, 0.17) log 10 IU/mL vs. 0.34 (0.13, 0.44) log 10 IU/mL, P<0.05]. Conclusion:The proportions of CD8 +PD-1 +T cells and CD8 +CD161 +T cells were significantly regulated by PEG-IFN-α therapy in the peripheral blood of patients with CHB, revealing the important role of T cell immune activation status during antiviral treatment. The gradual decline of HBsAg is closely related to the high expression of PD-1, suggesting that PD-1 may be negatively regulated during the process of T cell exhaustion and immunological evasion.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

ObjectiveTo investigate the effect and mechanism of Sishenwan in restoring the intestinal barrier function in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency based on intestinal flora and short-chain fatty acids. MethodsAfter the delivery of 10 SPF-grade pregnant rats， 4 male suckling rats were kept in each litter for the experiment. The male suckling rats were randomly allocated into blank， model， low-dose （3.51 g·kg^-1） Sishenwan， high-dose （7.02 g·kg^-1） Sishenwan， and Peifeikang （0.54 g·kg^-1） groups， with 8 rats in each group. The blank group was fed conventionally， and the other groups were subjected to mother-child separation and Sennae Folium gavage （1 g·mL^-1， 10 mL·kg^-1） for the modeling of IBS-D due to spleen-kidney Yang deficiency. After the modeling was completed， the rats in Sishenwan groups were administrated with the corresponding dose of Sishenwan decoction by gavage， and the Peifeikang group with bifidobacterium triple live powder+normal saline suspension. The blank and model groups were treated with an equal volume of normal saline by gavage. The general conditions and fecal characteristics of rats were observed. After 2 weeks of administration， the rats were anesthetized for sample collection. The pathological changes of the colon tissue in rats were observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to measure the levels of transforming growth factor-beta （TGF-β）， interleukin-10 （IL-10）， and interleukin-22 （IL-22）. Immumohistochemical staining （IHC） was performed to detect the positive expression of zonula occludens-1 （ZO-1） and occludin in the colon tissue. Western blot was employed to determine the protein levels of ZO-1 and occludin in the colon tissue of rats， and 16S rRNA gene sequencing was performed for intestinal flora. Gas chromatography-mass spectrometry was employed to determine the content of short-chain fatty acids （SCFAs） in the cecum contents of rats. ResultsThe colon tissue in the blank group presented a clear structure， neat glands， and no inflammatory cell infiltration. In the model group， the colon tissue showcased a disorganized structure， irregular arrangement of glands， and inflammatory cell infiltration. Compared with the model group， the low-dose and high-dose Sishenwan groups and the Peifeikang group exhibited an intact colon tissue structure， regular arrangement of glands， and reduced inflammatory cell infiltration. Compared with the blank group， the modeling lowered the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.01）， down-regulated the protein levels of ZO-1 and occludin in the colon tissue （P<0.01）， and decreased the content of acetic acid and propionic acid and increased the content of butyric acid in cecum contents （P<0.05）. Compared with the model group， low-dose and high-dose Sishenwan raised the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.05， P<0.01）， and Peifeikang elevated the levels of TGF-β and IL-10 in the serum （P<0.01）. High-dose Sishenwan and Peifeikang up-regulated the protein levels of ZO-1 and occludin （P<0.05， P<0.01）， increased the content of acetic acid and propionic acid in cecum contents （P<0.05）， and decreased the content of butyric acid （P<0.05）. The 16S rRNA gene sequencing results showed that the intestinal flora structure of the model group changed compared with that of the blank group. Compared with the model group， Sishenwan and Peifeikang increased the relative abundance of Lachnospiraceae， Muribaculaceae， Akkermansiaceae， Ligilactobacillus， UBA3282， Akkermansia， and Corynebacterium while reducing the relative abundance of Oscillospiraceae， Desulfovibrionaceae， Lactobacillus， Romboutsia， and Desulfovibrio. They can restore the intestinal flora structure similar to that in the blank group. ConclusionSishenwan can alleviate diarrhea symptoms and colonic mucosal inflammation， increase the expression of tight junction proteins in the colonic mucosa， and strengthen the intestinal barrier in IBS-D rats with the syndrome of spleen-kidney Yang deficiency. The mechanism of action may be related to optimizing the structure and balance of intestinal flora and regulating the SCFAs， and the effect of high-dose Sishenwan is obvious.
