ObjectiveTo observe the activation patterns and functional connectivity in the prefrontal cortex of patients with post-stroke anxiety (PSA) using functional near-infrared spectroscopy, in order to explore the underlying neural mechanism. MethodsFrom December, 2024 to September, 2025, 120 stroke patients were selected in Changzhou De'an Hospital. They were divided into PSA group (n = 60) and non-PSA group (n = 60) according to the score of Hamilton Anxiety Scale (HAMA). All patients wore an 18-channel fNIRS acquisition cap for detection. The differences in resting-state functional connectivity between the frontopolar cortex (FPC) and dorsolateral prefrontal cortex (DLPFC) were examined in both groups, as well as task-related activation in these brain regions. ResultsResting-state functional connectivity analysis revealed no statistically significant difference in network connectivity between two groups in the FPC and DLPFC regions (|t| < 1.301, P > 0.05). Task-related activation results revealed significantly reduced activation in the contralateral FPC of PSA group compared to the non-PSA group (Z = -2.063, P < 0.05). Activation levels in this region showed a negative correlation with the scores of HAMA (ρ = -0.201, P = 0.028). ConclusionActivation decreased in the contralateral frontal pole during the task state for patients with PSA, and the activation levels negatively correlates with anxiety severities.

Objective:To investigate the application value of intraoperative electrocochleography（ECochG） monitoring technique and insertion techniques in cochlear implant（CI） and analyze its relationship with postoperative residual hearing（RH） preservation. Methods:Thirty-one patients（35 ears） who received CI in our hospital from June 2022 to July 2024 were enrolled. The Advanced Bionics Active Insertion Monitoring（AIM） system was used for real-time ECochG monitoring during surgery. Intraoperative cochlear microphonics （CM） waveform changes were recorded and analyzed in relation to postoperative RH preservation. Results:①ECochG recordings were successfully obtained in 34 of 35 ears （97.1%）. ②According to Harris classification, there were 7 ears（20.6%） of Type A（rising）, 7 ears（20.6%） of Type C（declining）, 8 ears（23.5%） of Type CC（fluctuating）, and 12 ears（35.3%） of Type D（no response）. ③The total CM amplitude decrease was significantly moderately correlated with postoperative low-mid frequency hearing loss（r=0.67, P=0.017）. The total CM amplitude decrease was significantly moderately correlated with postoperative low frequency hearing loss（r=0.65, P=0.023）. ④For the mean amplitude variation, the Amax was 30.70 μV, the Amin was 8.64 μV, and the Aend was 18.27 μV. ⑤Sixteen cases completed postoperative follow-up, with an average low-mid frequency（125-1 000 Hz） residual hearing loss of 15.25 dB HL and a RH preservation rate of 87.5%. Conclusion:Intraoperative ECochG monitoring can effectively predict postoperative residual hearing changes, effectively guide surgical manipulation, and improve residual hearing preservation rate.

Objective:To evaluate the effect of enhance recovery after surgery-multidisciplinary treatment (ERAS-MDT) modality on elderly patients with knee osteoarthritis who underwent unicompartmental knee arthroplasty.Methods:This was a single-center, retrospective study: from August 2018 to September 2023, the data of 68 elderly patients (11 males and 57 females, aged from 75 to 91 years) who suffered from knee osteoarthritis came to Departmentof Orthopaedic Surgery, Beijing Geriatrics Hospital and underwent unicompartmental knee arthroplasty were collected and analyzed. The 36 patients who managed by ERAS-MDT modality were allocated to observational group, while the 32 patients who managed by the traditional treatment modality were allocated to the control group. The visual analogue score (VAS) was used to evaluate the pain extent, while the Oswestry disability index (ODI) was used for assessing the functional status. The efficiency was evaluated by the time interval between admission and surgery, time of the first off-bed ambulation training and hospital stays. The incidence rate of perioperative complications was collected. The modified MacNab criterion was used to assess the patient′s opinion of treatment satisfaction at the final follow-up.Results:The mean follow-up period was (8.3 ± 2.6) months. No significant differences were found pertaining to the demographic and baseline characteristics between the two groups ( P>0.05). All patients showed significantly improvement in leg pain and functional disability during the postoperative follow-up; the VAS and ODI scores in the observational group were significantly lower than that in the control group at the early postoperative follow-ups. The efficiency of diagnosis and treatment in the observational group were significantly higher than those in the control group, including the time interval between admission and surgery, time of the first off-bed ambulation training and the hospital stay: (2.8 ± 0.6) d vs. (3.7 ± 0.9) d, (0.9 ± 0.2) d vs. (2.1 ± 0.3) d and (14.8 ± 1.2) d vs. (17.7 ± 1.5) d, and there were statistical differences ( P<0.01). The incidence rate of perioperative complications in the observational group was significantly lower than that in the control group: 2.8% (1/36) vs. 18.8% (6/32), and there was statistical difference ( P<0.05). At the final follow-up, 94.4% (34/36) of patients in the observational group and 75.0% (24/32) of patients in the control group were satisfied with the treatment, the between-group difference was statistical significant ( P<0.05). Conclusions:Improved labor division and perioperative measurements can be implemented with the application of ERAS-MDT modality. Elderly patients who suffered from knee osteoarthritis would benefit from this improved treatment modality, achieving better treatment efficiency, enhanced recovery after surgery, as well as reduced incidence rate of perioperative complications.

Objective To analyze the publication condition and development trends of global post-stroke fatigue(PSF)research from 2004 to 2024.Methods Relevant literature on PSF pub-lished between January 1,2004,and August 1,2024,were systematically searched and screened from WoSCC database.Visual analysis of publication volume,contributing countries,institutions,authors,and keywords in PSF research was conducted using CiteSpace software.Results A total of 373 articles were included in this study.The overall publication volume related to PSF exhibited an upward trend.The country,institution,and author with the highest number of publications were the United Kingdom,the University of Oslo,and LERDAL A,respectively.High-frequency keywords in-cluded quality of life,depression,fatigue severity scale,follow up,epidemiology,symptoms,associ-ations,and rehabilitation,while the emerging keywords were health care professionals,risk factors,and participation.Conclusion PSF-related research has demonstrated an overall upward trend.As-sessment and measurement protocols,rehabilitation treatment approaches,impacts on quality of life,and the intrinsic relationship with depression have emerged as research hotspots.Further exploration of precise and systematic assessment methods,along with the construction of scientific rehabilitation management programs and risk prediction models,will become the focal points of future research.

Objective:To study and analyze the brain networks of hemiplegic stroke patients in a resting state or during virtual reality(VR)upper limb rehabilitation robot training by functional near-infrared spectroscopy(fNIRS).Method:Fourteen hemiplegic stroke patients were included in this study as the test group,while 14 healthy subjects were recruited as the control group.The fNIRS data of the two groups were collected during the rest-ing state or the VR upper limb rehabilitation robot training.The functional connectivity(FC)index of the brain network was calculated.Result:①No significant difference was found between the test group and the control group in FC in the rest-ing state(P>0.05).②The overall FC of the control group did not increase significantly in the VR task com-pared with the resting state(P>0.05).But the FC of the LSMA-RPFC increased significantly(P<0.05).③The overall FC of the test group decreased in the VR task compared with the resting state(P<0.05),of which the LSMA-RPFC decreased(P<0.05).④The overall FC of the test group was lower than that of the control group(P<0.05),in which there was a significant difference in FC between LSMA-RSMA,LSMA-LM1,LS-MA-RM1,LSMA-RS1,and LM1-RS1(P<0.05)when the test group and the control group performed the VR upper limb rehabilitation robot training task.Conclusion:VR upper limb rehabilitation robot training can induce plastic reorganization of the extensive sen-sorimotor network in hemiplegic patients with stroke.And the mechanism of improving upper limb function may be related to the FC changes between bilateral SMA and SMA and other brain regions.

Objective:To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness.Methods:The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group. The abnormal group was further divided into three subgroups: those with non-absorbed high signal in the inner ear, those with absorbed high signal, and those with destruction of the blood-labyrinth barrier. SPSS 26.0 statistical software was applied to analyze the differences in hearing efficacy, caloric tests, vestibular evoked myogenic potentials (VEMP), video head impulse tests (vHIT), and the incidence of dizziness/vertigo among various patient groups.Results:A total of 191 patients with complete data were collected (97 males and 94 females, aged from 13 to 69 years old). There were 50 cases in the normal inner ear 3D-Flair MRI group. A total of 141 cases were found in the group with abnormal 3D-Flair MRI, including 50 cases of high signal unabsorbed, 71 cases of absorption high signal and 20 cases of blood labyrinth barrier destruction. There were no significant differences in age, sex, lateral ratio of hearing loss and course of disease among four groups (all P>0.05).The significant efficiencies of hearing recovery, in the group with normal 3D-FLAIR MRI were better than those in the abnormal group ( P<0.05) after treatment. Among the four groups, there were significant differences in the apparent efficiency and total effective rate between the normal group and the inner ear high signal absorption group ( χ2=4.007, P=0.045; χ2=6.925, P=0.009). The abnormal rates of bithermal caloric test, vHIT results and dizziness/vertigo symptoms in the abnormal group were higher than those in the normal group ( P<0.05). There were significant differences in oVEMP abnormality rate, vHIT abnormality rate and incidence of dizziness/vertigo among the three groups with 3D-FLAIR MRI abnormality ( P<0.05). There were significant differences in caloric test, oVEMP, vHIT abnormality rate and incidence of dizziness/vertigo among the four groups ( P<0.05). The positive rates of caloric test, cVEMP test and vHIT test in patients with dizziness/vertigo were higher than those in patients without dizziness/vertigo ( P<0.05). The abnormal rates of posterior semicircular canal and horizontal semicircular canal in patients with dizziness/vertigo were significantly increased ( P<0.05) than patients without dizziness/vertigo. The recovery rate, effective rate and total effective rate of patients without dizziness/vertigo were significantly better than those with dizziness/vertigo ( P<0.05). Conclusions:The 3D-Flair MRI of the inner ear and vestibular function tests have reference value for the prognosis assessment of patients with severe sudden sensorineural hearing loss. Abnormal 3D-FLAIR MRI of the inner ear, especially absorption high signal, is associated with high incidence of vestibular dysfunction and dizziness/vertigo, with poor prognosis. Patients with severe sudden sensorineural hearing loss who have symptoms of dizziness/vertigo are more likely to exhibit abnormal results in vestibular function tests, with a higher susceptibility to involvement of the posterior and horizontal semicircular canals.

Objective To investigate the effect of Echinacoside(Ech)on liver injury in hepatitis B rats.Methods SD rats were divided into control group,Hepatitis B(HBV,5 mL/kg HBV virus was injected into the tail vein twice a week for 3 consecutive weeks),low(Ech-L)and high(Ech-H)doses of Ech were injected into the stom-ach for HBV(8.33 and 33.32 mg/kg,respectively),HBV group was treated with positive drugs(lamivudine,10 mg/kg)and Ech-H+BKM120(40 mg/kg BKM120),with 12 animals in each group.The drug was administered once a day for 8 weeks.The activity of ALT and AST in serum of were detected.Serum level of gam-ma-interferon(IFN-γ)and interleukin(IL-4)was detected by ELISA;Flow cytometry was applied to detect Th1/Th2 in peripheral blood;Chromatin immunoprecipitation was applied to detect HBV DNA expression in liver tissue;HE staining was used to detect the pathological changes of liver tissue and score the damage;Western blot was ap-plied to detect phosphorylated phosphatidylinositol 3 kinase(p-PI3K),phosphorylated protein kinase B(p-AKT)proteins in liver tissue.Results Compared with the control group,hepatocytes in the hepatitis B group were swollen,nuclear staining was excessive,hepatic lobular structure was disorganized,pathological injury score,serum AST,ALT activity,IL-4 level,peripheral blood Th2,HBV DNA expression in liver tissue were all increased.Serum IFN-γ level,Th1,Th1/Th2 in peripheral blood,p-PI3K and p-AKT protein in liver tissue were all decreased(P＜0.05);Treatment with Ech-L,Ech-H and lamivudine reduced the swelling of HBV rat hepatocytes,cleared the structure of some liver cords,reduced pathological injury score,the activity of AST,ALT and IL-4 levels in serum,Th2 in peripheral blood and HBV DNA in liver tissue;The level of serum IFN-γ,Th1,Th1/Th2 in peripheral blood,and protein expression p-PI3K and p-AKT protein in liver tissue were increased(P＜0.05).BKM120 attenuated the ameliorative effect of high-dose Ech on hepatitis B-induced liver injury in rats.Conclusions Ech ameliorates liver in-jury in rats with hepatitis B,and the mechanism may be related to the activation of the PI3K/AKT pathway.

Objective:To evaluate the safety and effectiveness of fuzuloparib for the treatment of ovarian epithelial cancer patients in the real world setting.Methods:A retrospective analysis was conducted on the baseline data of 4 620 ovarian cancer patients who had received fuzuloparib monotherapy or combination therapy.
