Objective:To describe the trend of changes in the disease burden of age-related hearing loss in China and globally from 1990 to 2021,to forecast the prevalence and years lived with disability(YLD)rates of age-related hearing loss from 2022 to 2036,and to provide a reference for the prevention and control of the disease burden associated with age-related hearing loss.Methods:Using the Global Burden of Disease 2021(GBD2021)data,this study selected age-standardized prevalence rate(ASPR)and YLD as indicators.The disease burden and long-term trends of age-related hearing loss in China and globally from 1990 to 2021 were described by different socio-demographic index(SDI)and gender.Joinpoint regression was used to calculate the average annual percent change(AAPC)to assess the trend changes in the disease burden.Decomposition analysis was applied to explore the relative im-pacts of aging,population growth,and epidemiological changes on the variation in disease burden.An autoregressive integrated moving average(ARIMA)model was used to forecast the age-standardized pre-valence rate and YLD rates from 2022 to 2036.Results:The prevalence of age-related hearing loss in China in 2021 was 82 162.49(73 288.08-89 187.21)per 100 000,higher than the global SDI level of 66 238.16(59 982.54-72 669.82)per 100 000,the high SDI region's level of 57 650.42(52 059.12-63 889.02)per 100 000,the upper-middle SDI region's level of 69 115.59(62 494.18-75 340.64)per 100 000,the middle SDI region's level of 72 365.56(65 181.43-78 912.01)per 100 000,the lower-middle SDI region's level of 64 439.66(58 368.22-71 468.27)per 100 000,and the low SDI region's level of 61 725.25(55 749.18-68 477.67)per 100 000.The age-related hearing loss YLD rate in China was 2 762.98[95％uncertainty interval(UI):1 855.28-3 880.68]per100000,higher than the global SDI level of 2 236.75(95％UI:1 511.56-3 155.88)per 100 000,the high SDI region's level of 1 805.79(95％UI:1 212.69-2 577.17)per 100 000,the upper-middle SDI re-gion's level of 2 316.58(95％UI:1 557.53-3 274.87)per 100 000,the middle SDI region's level of 2 480.99(95％UI:1 678.17-3 489.24)per 100 000,the lower-middle SDI region's level of 2 313.28(95％UI:1 578.35-3 271.50)per 100 000,and the low SDI region's level of 2 383.55(95％UI:1 623.66-3 365.68)per 100 000.From 1990 to 2021,both the prevalence and YLD rate of age-related hearing loss in China showed an increasing trend,rising by an average of 0.18％(95％CI:0.16％-0.19％)and 0.29％(95％CI:0.27％-0.30％)per year,respectively.The rates of in-crease in prevalence were the same for both men and women,with men showing a 0.18％increase(95％CI:0.17％-0.19％,P＜0.001)and women showing a 0.18％increase(95％CI:0.16％-0.19％,P＜0.001).However,the YLD rate increase was faster in men than in women,with men experiencing a 0.32％increase(95％CI:0.27％-0.37％,P＜0.001)and women experiencing a 0.27％increase(95％CI:0.26％-0.28％,P＜0.001).Decomposition analysis showed that population growth was the main factor driving the increase in prevalence and YLD rate globally and across different SDI regions.However,aging was the primary factor contributing to the increase in prevalence and YLD rate in China.ARIMA model predictions suggested that the prevalence and YLD rate of age-related hearing loss would continue to rise from 2022 to 2036,with the predicted prevalence and YLD rate in 2036 reaching 89 723.99 per 100 000 and 2 872.47 per 100 000,respectively.Conclusion:The prevalence and disease burden of age-related hearing loss in individuals aged 60 and above in China rank first globally.From 1990 to 2021,both the prevalence and YLD rate of age-related hearing loss have shown a continuous upward trend,consistently surpassing the levels observed in various SDI regions worldwide.The prevalence and disease burden of age-related hearing loss are particularly significant among elderly men.Moreover,projections indicate that the disease burden of age-related hearing loss will continue to rise over the next 15 years.Therefore,it is urgent to pay close attention to age-related hearing loss in this specific population,and early intervention measures are crucial to reduce the disease burden associated with age-related hearing loss.

Objective:To analyze the clinical features, imaging features and diagnosis and treatment process of a female pelvic epithelioid inflammatory myofibroblastic sarcoma (EIMS) with peritoneal metastasis, so as to improve the clinical understanding and diagnostic ability of the disease and avoid misdiagnosis and missed diagnosis.Methods:The clinical data of a female patient with pelvic EIMS combined with peritoneal metastasis in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed.Results:The triad examination of the patient involved an irregular solid mass in the pelvic cavity about 8.0 cm×9.0 cm in size. Laboratory examination revealed human epididymal protein 4(HE4)154.00 pmol/L. The ultrasonography showed multiple low-echo masses in deep pelvic cavity with unclear boundary and uneven internal echo, and color doppler flow imaging (CDFI) showed abundant internal blood flow signals. Enhanced CT showed uneven and obvious enhancement of the lesion. Pathological examination showed the infiltration of inflammatory cells in the mucous interstitial background. The tumor cells were round and epithelioid, with large nuclei, deep staining and obvious nucleolus. Immunohistochemistry showed anaplastic lymphoma kinase (ALK) positive, and molecular pathology fluorescence in situ hybridization showed ALK gene amplification (positive). Combined with pathological, immunohistochemical and genetic tests, EIMS was diagnosed. Conclusions:EIMS should be considered when there are single or multiple solid or cystic nodules or masses in the pelvic cavity with obvious enhancement, invasive growth and peritoneal implantation metastasis, and the correct diagnosis can be made according to the pathological findings, immunohistochemistry and genetic test results.

Objective To observe the value of subchondral bone(SB)intravoxel incoherent motion diffusion weighted imaging(IVIM-DWI)for quantitatively evaluating knee joint cartilage degeneration.Methods Totally 125 patients with knee cartilage degeneration were prospectively enrolled and divided into mild group(n=65,Outerbridge grades Ⅰ-Ⅱ)and moderate-severe group(n=60,Outerbridge grades Ⅲ-Ⅳ)based on arthroscopic findings.Additionally,30 healthy young subjects were recruited as control group.The apparent diffusion coefficient(ADC),true diffusion coefficient(D),pseudo diffusion coefficient(D*)and perfusion fraction(f)values of medial condyle of SB of femur,lateral condyle of femur,medial tibial plateau and lateral tibial plateau,as well as the mean values of each parameter of the above 4 regions were obtained based on knee joint IVIM-DWI and compared within and among groups.Spearman correlation analysis was used to observe the correlations between quantitative parameters and Outerbridge grading.The area under the receiver operating characteristic curve(AUC)was calculated to evaluate the efficacy of each quantitative parameter alone and their combination for assessing knee cartilage degeneration.Results Significant differences of D*values were found among different parts of knee joint SB in moderate-severe group,also of D value,D* value and f value among different parts of knee joint SB in mild group(all P＜0.05).Significant differences of IVIM-DWI parameter were found among different parts of knee joint SB in control group(all P＜0.05).ADC value of knee joint SB in moderate-severe group,mild group and control group decreased successively,while D value increased successively(all P＜0.001).D* values of knee joint SB in moderate-severe group was higher than that in mild group and control group(both P＜0.05).No significant difference of f value of knee joint SB was found between moderate-severe group and mild group(P＞0.05),while both the latter two were higher than that in control group(both P＜0.05).ADC value,D value and f value of knee joint SB were positively correlated(rs=0.671,0.634,0.416,all P＜0.01),while D* value of knee joint SB was negatively correlated with Outerbridge grading(rs=-0.729,P＜0.01).AUC of combination of parameters for distinguishing mild group from control group,and mild group from moderate-severe group was 0.859 and 0.808,respectively.Conclusion SB IVIM-DWI could be used for quantitatively evaluation of knee cartilage degeneration.

Objective To investigate the effects of Tongyangxiao(TYX)lotion on the healing of infected wounds and the expression of interleukin(IL)-1β and inhibitor of nuclear factor κBα(IκBα)/p65 in rats.Methods Fifty rats were randomly assigned to the model group,potassium permanganate(PP)group,and low-,medium-,and high-dose(TYX-L,TYX-M,TYX-H)groups,with 10 rats in each group.An open infection model of full-thickness skin defects was established,and the rats in each group were treated with the corresponding medicinal solution for dressing changes once a day for a total of 14 days.The wound healing of rats was observed,and immunofluorescence,immunohistochemistry,and Western blotting were used to detect the nuclear translocation rate of p65 and the expression levels of IL-1β,p-IκBα/IκBα,and p-p65/p65 proteins in the granulation tissue.Results Compared with the model group,the wound healing rates of both the TYX-M group and the TYX-H group increased on the 7th day of treatment(P<0.05).Compared with the model group and the PP group,the wound healing rates of the TYX-L group,the TYX-M group and the TYX-H group increased on the 14th day of treatment(P<0.05).On the 7th day of treatment,the expression of IL-1β in the TYX-M group was lower than that in the PP group and the Model group(P<0.05),and the p-IκBα/IκBα ratio in the TYX-H group was lower than that in the PP group and the model group(P<0.05).The nuclear translocation rates of p65 in the TYX-L group,TYX-M group and TYX-H group were lower than those in the PP group and model group(P<0.05).On the 14th day of treatment,the p-p65/p65 ratio in the TYX-H group and the TYX-M group was lower than that in the model group(P<0.05),and the IL-1β in the TYX-L group,the TYX-M group,and the TYX-H group and p-IκBα/IκBα ratio in the TYX-H group were lower than those in the PP group and the model group(P<0.05).Conclusion The mechanism of TYX lotion in promoting the healing of infected wounds was associated with the suppression of the activation of NF-κB signaling pathway and alleviation of inflammatory responses.

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

Alternative polyadenylation(APA)is a crucial step in post-transcriptional regulation.Previous bioinformatic studies have mainly focused on the recognition of polyadenylation sites(PASs)in a given genomic sequence,which is a binary classification problem.Recently,computa-tional methods for predicting the usage level of alternative PASs in the same gene have been pro-posed.However,all of them cast the problem as a non-quantitative pairwise comparison task and do not take the competition among multiple PASs into account.To address this,here we propose a deep learning architecture,Deep Regulatory Code and Tools for Alternative Polyadenylation(DeeReCT-APA),to quantitatively predict the usage of all alternative PASs of a given gene.To accommodate different genes with potentially different numbers of PASs,DeeReCT-APA treats the problem as a regression task with a variable-length target.Based on a convolutional neural network-long short-term memory(CNN-LSTM)architecture,DeeReCT-APA extracts sequence features with CNN layers,uses bidirectional LSTM to explicitly model the interactions among com-peting PASs,and outputs percentage scores representing the usage levels of all PASs of a gene.In addition to the fact that only our method can quantitatively predict the usage of all the PASs within a gene,we show that our method consistently outperforms other existing methods on three different tasks for which they are trained:pairwise comparison task,highest usage prediction task,and rank-ing task.Finally,we demonstrate that our method can be used to predict the effect of genetic variations on APA patterns and sheds light on future mechanistic understanding in APA regulation.
