ObjectiveTo identify potential influencing factors of urate crystal deposition at ankle/foot in patients with hyperuricemia （HUA）， and to analyze the predictive value of inflammatory indicators for urate crystal deposition in patients with different traditional Chinese medicine （TCM） syndromes， so as to provide potential reference for clinical risk assessment and individualized TCM intervention. MethodsA retrospective study was carried out with the enrollment of 231 HUA patients from The Third Affiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2021 and December 2024. The enrolled patients were further divided into a crystal deposition-positive group （143 cases） and a crystal deposition-negative group （88 cases） according to the results of dual-energy computed tomography （CT）. Sociodemographic data， living habits， serum uric acid levels， and inflammatory indicators of the enrolled patients were collcted， and TCM syndrome differentiation was performed. Furthermore， univariate analysis was used to compare inter-group differences in clinical characteristics. MMultivariate Logistic regression was applied to identify the influencing factors of urate crystal deposition. In addition， the receiver operating characteristic （ROC） curves were plotted to evaluate the predictive efficacy of inflammatory indicators for crystal deposition across different TCM syndromes. ResultsThere were statistically significant inter-group differences in the proportion of males， age， body mass index， proportion of mental labor， rate of low water intake， and rate of high-sugar beverage consumption （P<0.05），whereas no significant difference in low exercise intensity was found between the two groups. Furthermore， compared with the negative group， the positive group had higher serum uric acid level， neutrophil-to-lymphocyte ratio （NLR）， and platelet-to-lymphocyte ratio （PLR）， but lower systemic immune-inflammation index （SIRI） （P<0.05）. Regarding the distribution of TCM syndromes， the positive group was dominated by the dampness-heat accumulation syndrome （55/143，38.46%）， while the negative group was mainly characterized by the phlegm-turbidity obstruction syndrome （44/88，50.00%）. Multivariate Logistic regression analysis revealed that high-sugar beverage consumption， elevated NLR， and elevated PLR were risk factors for urate crystal deposition ［odd ratio （OR） = 8.002， 5.377， 1.034， respectively； 95% CI 1.572-40.732， 2.179-13.270， 1.013-1.054，all P<0.05］， while SIRI was a protective factor （OR = 0.869， 95% CI 0.778-0.971， P<0.05）. In the positive group， patients with the dampness-heat accumulation syndrome exhibited the highest NLR， while the lowest PLR and SIRI， showing statistically significant differences with those of other syndromes （all P<0.05）. In addition， ROC curve analysis indicated that for the dampness-heat accumulation syndrome， the combined "NLR + PLR" model had an area under the curve （AUC） of 0.901 （95% CI 0.850-0.951， P<0.01）， with a sensitivity of 89.1% and a specificity of 79.5%； for the blood stasis-heat obstruction syndrome， the combined "NLR + PLR" model had an AUC of 0.880 （95% CI 0.825-0.934， P<0.01）， with a sensitivity of 100.0% and a specificity of 67.3%； for the liver-kidney Yin-deficiency syndrome， the single PLR model had an AUC of 0.842 （95% CI 0.731-0.952， P<0.01）， with a sensitivity of 83.3% and a specificity of 84.0%. ConclusionUrate crystal deposition in HUA patients exhibits intimate associations with high-sugar beverage consumption as well as elevated NLR and PLR levels. Meanwhile， TCM syndrome differentiation has potential correlation with inflammatory characteristics. The inflammatory indicator-based prediction model constructed based on TCM syndromes exhibits good predictive value.

Objective:To evaluate the sound localization ability of patients with different degrees of unilateral conductive hearing loss (UCHL) in quiet and noisy environments, and to explore the changes and characteristics of sound localization.Methods:This was a cross-sectional study. 41 patients with UCHL were hospitalized in Shandong Provincial ENT Hospital from January to April 2024, including 22 males and 19 females, aged 18-55 years old, with an average age of 36.9 years. According to the pure-tone average (PTA) of 500, 1000 and 2000 Hz in the suffered ear, subjects were divided into slight-mild UCHL group (20 numbers) and moderate-moderately severe UCHL group (21 numbers). 21 patients with normal hearing (NH) were enrolled as controls. All subjects were assessed through pure-tone audiometry, horizontal sound localization test (including azimuth identification test in quiet and noisy environments), Chinese edition short form of Spatial Hearing Questionnaire (C-SHQ12) and twelve-item version of Speech, Spatial, and Qualities of Hearing Scale (SSQ12). SPSS, version 26.0, was used for statistical analysis.Results:There were significant differences in the root-mean-square errors (RMSE) of the sound localization azimuth identification test in quiet and noisy environments among the NH group, slight-mild UCHL group, and moderate-moderately severe UCHL group (Quiet: F=29.109, P<0.001; Noisy: F=24.351, P<0.001). This presented statistically marked difference in the RMSEs between the two listening environments in the slight-mild UCHL group ( t=-4.911, P<0.001). There was a statistical difference in the RMSEs between the normal and affected sides of the subjects in the slight-mild UCHL group in the quiet environment ( t=-2.055, P<0.05), but not in the noisy environment. For moderate-moderately severe UCHL subjects, there were no differences in the RMSEs between the quiet and noisy environments ( P>0.05). What’s more，no significant differences were found between normal side and affected side in both environments ( P>0.05). The RMSEs of UCHL patients in quiet and noisy environments were positively correlated with PTA of air-conduction in the suffered ears (Quiet: r=0.681, P<0.001; Noisy: r=0.346, P<0.05). RMSEs in quiet and noisy environments were negatively correlated with the average localization scores in C-SHQ12 (Quiet: r=-0.576, P<0.001, Noisy: r=-0.613, P<0.001) and in SSQ12 (Quiet: r=-0.634, P<0.001, Noisy: r=-0.663, P<0.001). Conclusions:The sound localization ability of UCHL subjects decreased compared with those with normal hearing, and the RMSE gradually increased with the worse of air conduction hearing threshold. The localization ability of UCHL subjects was further reduced in the noisy environment compared with that in the quiet environment. The slight-mild UCHL subjects had better localization performance in the normal ears while worse in the suffered ears, however, when they were in noisy environment or their hearing loss deteriorated, the localization advantage of the normal ears was no longer obvious, and both sides of the subjects presented poor localization performance.

Objective:To assess the sound localization ability of patients with unilateral sudden hearing loss during the early period of treatment, to explore its changing characteristics and to analyze influencing factors.Methods:A total of 22 patients with unilateral sudden sensorineural hearing loss, with onset within 3 days, who were hospitalized at Shandong Provincial ENT Hospital between January and April 2024, were collected in this study. The cohort included 13 males and 9 females, with a mean age of 36.5 years. Among them, 10 suffered in the right ear and 12 in the left ear. Additionally, 15 healthy individuals (8 males and 7 females, mean age 29.2 years) were selected as controls. Pure tone audiometry and sound localization tests were reviewed on the first day, third day, fifth day of admission; the third week after onset, and the pure tone average and the root-mean-square error(RMSE) were used as indicators, respectively. The improvement of the ability of sound localization and pure tone average were assessed by correlation analyses using SPSS, version 27.0, and multiple regression analysis was employed to explore effects that might influence sound localization ability.Results:The pure tone threshold and sound localization ability on the third week of onset were improved compared with those on the initial three instances(the first, third, and fifth days of admission). 9 of the 22 patients (40.91%, 9/22) presented normal sound localization ability whereas their hearing loss had not recurred yet. The Spearman correlation analysis revealed a significant positive correlation between the improvement of sound localization ability and hearing improvement ( r=0.57, P<0.001). Meanwhile, multiple regression analysis showed that hearing threshold was a significant factor for sound localization when there was audible frequency. Vice versa, at this circumstance, ages and vertigo were significant factors. Conclusions:For most of the patients with unilateral sudden hearing loss, ability of sound localization improves with the decrease of hearing threshold. Notably, some patients can restore normal levels of sound localization for white noise, even in the presence of hearing loss at certain frequencies, by relying on binaural acoustic cues provided by residual hearing.

OBJECTIVE: To investigate the early effectiveness of transiliac-transsacral screws internal fixation assisted by augmented reality navigation system HoloSight (hereinafter referred to as "computer navigation system") in the treatment of posterior pelvic ring injuries. METHODS: A retrospective analysis was made in the 41 patients with posterior pelvic ring injuries who had been treated surgically with transiliac-transsacral screws between June 2022 and June 2023. The patients were divided into navigation group (18 cases, using computer navigation system to assist screw implantation) and freehand group (23 cases, using C-arm X-ray fluoroscopy to guide screw implantation) according to the different methods of transiliac-transsacral screws placement. There was no significant difference in gender, age, body mass index, causes of injuries, Tile classification of pelvic fracture, days from injury to operation, usage of unlocking closed reduction technique between the two groups ( P>0.05). The time of screw implantation, the fluoroscopy times, the guide wire adjustment times of each screw, and the incidence of complications were recorded and compared between the two groups. The position of the transiliac-transsacral screw was scanned by CT within 2 days after operation, and the position of the screw was classified according to Gras standard. RESULTS: The operation was successfully completed in both groups. The time of screw implantation, the fluoroscopy times, and the guide wire adjustment times of each screw in the navigation group were significantly less than those in the freehand group ( P<0.05). There were 2 cases of incision infection in the freehand group, and the incision healed by first intention after active dressing change; there was no screw-related complication in the navigation group during operation and early period after operation; the difference in incidence of complications between the two groups (8.7% vs. 0) was not significant ( P=0.495). According to the Gras standard, the screw position of the navigation group was significantly better than that of the freehand group ( P<0.05). CONCLUSION Compared with the traditional freehand method, the computer navigation system assisted transiliac-transsacral screws internal fixation in the treatment of posterior pelvic ring injuries has advantages of improving the accuracy of screw implantation and reducing radiation damage and the time of screw implantation.
