Objective:To investigate the alterations of multilayer network and dynamic causal connectivity in patients with bilateral sudden sensorineural hearing loss.Methods:The hearing ability, neural-scale data and resting-state functional magnetic resonance imaging(fMRI)data of 60 patients with bilateral sudden sensorineural hearing loss from the Department of Otolaryngology and 60 healthy controls from Physical Examination Center, Nanjing First Hospital were collected from January 2022 to January 2024. Multilayer brain network analysis was computed to identify the nodes with abnormal switching rate. Then these abnormal nodes were used as regions of interest (ROIs) in the subsequent dynamic causal model analysis. The SPSS 26.0 software was used to analyze causal connectivity between two groups based on independent-sample Mann-Whitney U test. And Pearson correlation coefficients between fMRI results and clinical parameters were calculated. Results:Pure tone audiometry test showed that the left and right hearing thresholds of bilateral sudden sensorineural hearing loss were significantly higher than those of healthy controls( Z=-9.460, -9.462, both P<0.01). The score of depressive emotion in patients with bilateral sudden hearing loss was 6.00(2.00, 9.00).Multilayer brain network analysis showed that the switching rates in the left superior frontal gyrus (0.073(0.049, 0.102), Z=3.603, P<0.001), left anterior cingulate gyrus (0.077(0.044, 0.105), Z=3.189, P=0.001), right hippocampus (0.080(0.045, 0.116), Z=3.616, P<0.001), left para-hippocampal gyrus (0.080(0.043, 0.108), Z=3.577, P<0.001), left superior parietal gyrus (0.079(0.047, 0.103), Z=3.160, P=0.002), and right inferior parietal gyrus (0.078(0.043, 0.105), Z=3.396, P<0.001) in patients with bilateral sudden sensorineural hearing loss were lower that those in healthy controls. These six brain areas were used as ROIs to compute dynamic causal model analysis, and the results showed that the connection strength from left superior frontal gyrus to the left para-hippocampal gyrus in patients with bilateral sudden sensorineural hearing loss was significantly higher than that in healthy controls ( Z=-2.593, P<0.05). Additionally, enhanced connectivity from left superior frontal gyrus to the left para-hippocampal gyrus was positively correlated with duration of hearing loss ( r=0.376, P=0.003). Conclusions:Bilateral sudden sensorineural hearing loss patients have decreased switching rates in many brain areas, and the causal connectivity from left superior frontal gyrus to the left para-hippocampal gyrus is enhanced.

Hospital evaluation is a powerful tool for standardizing behavior and ensuring quality, which plays a positive role in improving medical services and hospital management. Establishing an evaluation system for world-class, high-quality and high-level hospitals with Chinese characteristics is an important basis for promoting the high-quality development of public hospitals and moving towards the construction of high-level hospitals. Based on the review of relevant policies and the current domestic and foreign mainstream hospital evaluation system, combined with the practical experience of public hospitals in the high-quality development in China, such as multi-campus management, discipline construction, scientific research innovation, talent construction, management innovation, cultural construction, radiation influence at home and abroad, the author tentatively explored the construction of high-quality and high-level hospital evaluation system from seven aspects of medical quality. It is expected to play a goal-oriented role in promoting the construction of " Chinese characteristics, world-class" hospitals.

Subjective tinnitus refers to the subjective sound perception of patients in the absence of an external sound stimulus.Tinnitus patients are often accompanied by emotional disorders, such as depression and anxiety, which seriously affect the quality of life of patients.Therefore, understanding the mechanism underlying the occurrence of tinnitus emotional disorders can help relieve the pain of tinnitus.Tinnitus was considered a simple ear disease in the early stages, but with the progress of neuroimaging technology and the development of animal models, increasing attention has been given to the changes in the neural structure and function of tinnitus patients.As a powerful technique for in vivo investigation of neural activity in the brain, multimodal magnetic resonance has been widely used in the study of subjective tinnitus.By observing the changes of brain structure in subjective tinnitus patients, the neural mechanism of the occurrence and development of tinnitus has been explored.This article reviewed recent multimodal magnetic resonance imaging studies on the neuroimaging mechanisms of tinnitus with mood disorders, compared the differences in neural activity between subjective tinnitus patients and healthy people, and found that the limbic system, default mode network and other neural network abnormalities were closely related to the mood disorders of tinnitus.The application and development of multimodal magnetic resonance techniques in subjective tinnitus were also discussed to elucidate the neural mechanism of subjective tinnitus accompanied by mood disorders with the help of multimodal magnetic resonance techniques.

Objective:To investigate the local consistency of inferior colliculus and ventrolateral orbital cortex by resting-state functional magnetic resonance imaging (fMRI) in rats with noise induced deafness and its relationship with anxiety- and depression-like behavior.Methods:Twenty-four clean grade male four-weeks old SD rats were randomly divided into noise group and control group with 12 rats in each group.Rats in the noise group were exposed to 122 dB broadband strong noise for 2 hours to induce severe bilateral hearing loss, while rats in the control group were placed in a quiet environment. Hearing thresholds were assessed by auditory brainstem response (ABR) test. The open field test (OFT) was conducted to examine anxiety-depression related behavior, and the local consistency in the rat brain was evaluated by fMRI.SPM12 software was used to process fMRI data, and Pearson correlation analysis was conducted by SPSS 22.0 software to calculate the correlation between fMRI data and behavior.Results:The results of ABR showed that the full band hearing threshold of rats in the noise group was higher than that of rats in the control group ((85.417±6.463) dB, (20.083±8.853) dB, t=46.168, P<0.001). And compared with control group, the rats in the noise group showed obvious anxiety-depression-like behavior in the open field test, that was, low activity level.The results of OFT showed that the total distance ((39.912±5.696) m, (47.993±10.820)m, t=-2.289, P=0.032), average moving speed ((13.306±1.900)cm/s, (15.998±3.607)cm/s, t=-2.290, P=0.032) and standing times ((13.333±5.960), (23.500±7.323), t=-3.730, P=0.001) of the rats in the noise group were all lower than those in the control group. Compared with the control group, the local consistency of hypothalamus in the noise group was significantly enhanced, while the local consistency of ventrolateral orbital cortex was significantly reduced, and the abnormal neural activity was lateralized. The correlation analysis showed that the neural activity of the inferior colliculus was negatively correlated with the total distance of rats in the noise group moving in the open field( r=-0.691, P=0.013), while the neural activity of the ventrolateral orbital cortex was not significantly correlated with the anxiety-depression-like behavior in the open field. Conclusions:The neural activity of inferior colliculus is closely related to anxious-depression behavior in rats with noise-induced deafness, while the ventrolateral orbital cortex may be related with other behaviors.

【Objective】 To compare and study the characteristics of blood donors with and without adverse reactions to apheresis platelet donation(ARAPD), and to study the influencing factors of blood donors participating in blood donation again, so as to provide basis for putting forward scientific and reasonable countermeasures and retaining blood donors to the greatest extent. 【Methods】 157 679 platelet donors from Tianjin Blood Center from December 26, 2015 to December 25, 2020 were selected and divided into ARAPD group(n=168) and non-ARAPD group (n=157 511). Such characteristics as sex, age, height, weight, blood type, educational background, first-time donation or not, platelet count, hematocrit, phlebotomy time, circulating blood volume and anticoagulant dosage of the two groups were analyzed. Chi-square test was used to identify the high-risk population with poor blood donation response. Multivariate binary logistic regression was used to study the influencing factors of blood donors returning. 【Results】 The age, height and weight of ARAPD group were lower than those of the non-ARAPD group, and the proportion of first-time blood donors, the proportion of women and phlebotomy time were higher than those of non-ARAPD group. There was little difference between the two groups in circulating blood volume, anticoagulant dosage, pre- and post-donation platelet count and hematocrit. Logistic regression analysis showed that the influencing factors of ARAPD were age, educational background, first-time donation or not and phlebotomy time, among which age and first-time donation or not were positively correlated, education and phlebotomy time were negatively correlated (P<0.05). 【Conclusion】 Female, low age, low height and weight, and less blood donation are the basic characteristics of high-risk people with ARAPD. Low age, high education, first-time blood donation and long phlebotomy time are the influencing factors that lead to donor lapsing. Therefore, countermeasures are put forward based on the above results.

OBJECTIVE: To analyze the clinical features and genetic basis of three children with mental retardation, language impairment and autistic features due to de novo variants of FOXP1 gene. METHODS: Clinical data of the children were collected.Trio-whole exome sequencing was carried out for the children and their parents. Pathogenicity of the variants was analyzed through bioinformatics prediction. RESULTS: All of the children had various degrees of mental retardation in conjunct with language deficit, global developmental delay, abnormal behavior and peculiar facial features, among whom two also developed autism spectrum disorders. The results of genetic testing showed that all three children harbored de novo variants of the FOXP1 gene, namely c.613_c.614delCTinsTA, c.1248delC and c.1393A>G. Two of these were frameshift variants and one was missense variant, which were all rated as pathogenic based on the guidelines of the American College of Medical Genetics (ACMG). Database search suggested that c.613_c.614delCTinsTA and c.1248delC were unreported previously. CONCLUSION For the three children from unrelated families with mental retardation in conjunct with language deficit, global growth delay, abnormal behavior and peculiar facial features, the c.613_ c. 614delCTinsTA, c.1248delC and c.1393A>G variants of the FOXP1 gene may be the pathogenic factors. Above cases have further expanded the genotype-phenotype profile of FOXP1 deficiency syndrome.

OBJECTIVE：To p rovide reference for improving the level of technological innovation and promoting the high-quality development of pharmaceutical industry in Fujian province. METHODS ：A total of 452 people were interviewed by relevant departments of pharmaceutical industry ，industry associations ，pharmaceutical enterprises and some consumers in Fujian province. After sorting out the interview data ，based on the theory of causal loop diagram and problem basic model methods ，the key variables and problem basic models affecting the technological innovation system of pharmaceutical industry in Fujian province were investigated . The leverage solutions and suggestions were put forward. RESULTS & CONCLUSIONS：The scientific and technological innovation environment ，managers’innovative ideas ，scientific and technological innovation motivation ，enterprise profits，product’s market competitiveness ，social organizations of pharmaceutical industry ，and industrialization of scientific and technological innovation achievements in the technological innovation system of pharmaceutical industry in Fujian province were closely related to the technological improvement of pharmaceutical industry in Fujian province. There were basic modes of “the rich getting richer ”for the technological innovation system of pharmaceutical industry in Fujian province ，i.e. the investment of external resources on scientific and technological innovation of pharmaceutical enterprises was mostly concentrated in the pharmaceutical enterprises above designated size. At the same time ，due to the lack of industry-research-university interaction and the unsmooth achievement transformation channel ，some small and medium-sized pharmaceutical enterprises with the potential of scientific and technological innovation or with traditional advantages may form the problem basic model “to attend to trifles and neglect the essentials”. It is suggested that the subjects related to pharmaceutical industry should give full play to the role of various scientific and technological platforms ，strengthen the attention and support to innovative small and medium-sized pharmaceutical enterprises ， create and optimize the financial service environment for scientific and technological innovation of pharmaceutical enterprises ，and support pharmaceutical enterprises with innovation power and potential to carry out technological innovation projects.

Objective: To explore characteristics of dynamic and static balance of children aged 8 to 10 years, and to provide a reference for prevention of injuries caused by physical activities among obese children and the choice of facilities for physical activities. Methods: Totally 100 obese children and 100 normal children were selected as the subjects by one legged jumps from 5 primary schools in economic and technological development district of Hefei, the proportion of male and female children was 1∶1 in each group. IIM-BAL-100 balance tester was used to assess the static balance ability under double feet standing with eyes closed and right foot standing with eyes opened. The dynamic balance of double feet standing with eyes opened was measured by the Balance check dynamic balance tester. Two factor analysis of variance (ANOVA) was used to examine the effect of obesity and gender on the dynamic and the static balance. Results: In the static balance ability, when standing with both eyes closed, there was no significant difference in all static balance values between groups, genders and the interaction between the two factors( F=2.33, 0.42 ,0.76, P >0.05). When standing on one foot with eyes opened, there was significant difference in the static equilibrium index between the groups and the gender( F=2.72, 3.07, P <0.05). In terms of dynamic balance ability, all the dynamic balance indexes had statistically significant differences among the groups( F=43.67, P <0.01). Conclusion Obesity can significantly reduce the ability of single leg static balance and dynamic balance in 8-10 year old children. Sex can significantly affect the single foot static balance ability of 8-10 year old children, but it has little effect on the dynamic balance ability of 8-10 year old children.
