ObjectiveTo investigate the possible mechanism of Huatan Sanjie Formula (化痰散结方, HSF) in treating Graves' disease (GD) from the perspective of thyroid angiogenesis. MethodsThirty-six BALB/c female mice were randomly divided into a normal control group (n=9) and a modeling group (n=27). Mice in the modeling group were injected with 2.0×109 PFU/ml of Ad-TSHR289 adenovirus into the tibialis anterior muscle to build GD model. Nine weeks after immunization, the successfully modeled mice were randomly divided into model group, methimazole (MMI) group and HSF group, with 9 mice in each group. The MMI group was given 5.2 mg/(kg·d) of methimazole tablets by gavage, while the HSF group was given HSF at a relative crude drug dosage of 7.02 g/(kg·d) by gavage. The normal control group and the model group were given 0.1 ml/10 g of pure water by gavage. All groups were administered intragastrically once a day for a total of 4 weeks. The levels of thyroxine (T4) and thyrotropin receptor autoantibodies (TRAb) in serum were detected by radioimmunoassay, while the pathological changes of the thyroid gland were assessed by HE staining. The vascular morphology of thyroid tissue was observed by CD34 immunohistochemical staining, and the microvessel density (MVD) was counted. The protein expression of vascular endothelial growth factor A (VEGFA) and vascular endothelial growth factor receptor 2 (VEGFR2) in thyroid was detected by Western-blot. ResultsCompared to those in the normal control group, the thyroid volume of the mice in the model group significantly increased with excessive congestion, and the pathology showed significant thyroid follicular hyperplasia, columnar and proliferated epithelial cells, and enlarged follicle size; serum T4 and TRAb significantly increased, as well as the count of thyroid MVD, and the protein expressions of thyroid VEGFA and VEGFR2 (P<0.01). Compared to those in the model group, the thyroid glands of the mice in the MMI group and the HSF group were significantly reduced, and the congestion was improved; pathology showed that thyroid follicular hyperplasia and epithelial cell proliferation were reduced, with smooth edges of the follicles and the significantly reduced inward protrusion; serum T4 and TRAb significantly decreased, as well as the thyroid MVD, thyroid VEGFA and VEGFR2 protein expressions (P<0.05 or P<0.01). There was no significant difference in all indicators between the MMI group and the HSF group (P>0.05). ConclusionHSF may inhibit thyroid angiogenesis by down-regulating thyroid VEGFA/VEGFR2 signaling pathway, thereby improving goitre and hyperfunction in GD mice.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Objective:To evaluate inflammation early in the infarct zone and its dynamic changes after acute myocardial infarction (AMI) using 18F-FDG PET imaging, and analyze its relationship with left ventricular remodeling progression (LVRP). Methods:Sixteen Bama miniature pigs (4-6 months old, 8 females) were selected. AMI models were established by balloon occlusion of the left anterior descending artery. 18F-FDG PET imaging was performed before AMI and at days 1, 5, 8, and 14 post-AMI to evaluate the regional inflammation response. 18F-FDG SUV ratio (SUVR) and the percentage of uptake area of left ventricle (F-extent) in the infarct zone, and the SUVRs of the spleen and bone marrow, were measured. Echocardiography and 99Tc m-methoxyisobutylisonitrile(MIBI) SPECT myocardial perfusion imaging (MPI) were performed at the above time points and on day 28 post-AMI to assess left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and myocardial perfusion defect extent. The degree of LVRP at day 28 post-AMI was defined as ΔLVESV(%)=(LVESV AMI 28 d-LVESV AMI 1 d)/LVESV AMI 1 d×100%. Data were analyzed using repeated measures analysis of variance, Kruskal-Wallis rank sum test and Pearson correlation analysis. Results:Twelve pigs were successfully modeled and completed the study. Inflammation in the infarct zone persisted until day 14 post-AMI. The SUVR of the infarct zone pre-AMI and at days 1, 5, 8, and 14 post-AMI were 1.03±0.08, 3.49±1.06, 2.93±0.90, 2.38±0.76, and 1.63±0.62, respectively ( F=49.31, P<0.001). The F-extent values in the infarct zone pre-AMI and at days 1, 5, 8, and 14 post-AMI were 0, (40.08±12.46)%, (40.00±12.76)%, (31.08±12.82)%, and 16.50%(7.25%, 22.00%), respectively ( H=37.61, P=0.001). There were no significant differences in the SUVRs of bone marrow and spleen before and after AMI ( F values: 0.69 and 0.77, both P>0.05). At day 1 post-AMI, both SUVR and F-extent in the infarct zone were significantly correlated with LVRP ( r values: 0.82 and 0.70, P values: 0.001 and 0.035). Conclusions:18F-FDG PET imaging can be used to evaluate inflammation in the infarct area and its dynamic changes after AMI. Inflammation in the infarct area is severe at day 1, and then gradually decreases. The extent and severity of inflammation visible on 18F-FDG PET imaging 1 d after AMI are closely related to LVRP.
