Abstract
In this study, 16 new compounds, six bibenzyls (1-6) and 10 naphthalenes (7-13), including three pairs of naphthalene enantiomers and three known compounds (14-16), were isolated from Dendrobium chrysanthum. Structurally, compounds 1-5 are previously undescribed dimeric bibenzyls, uniquely linked by unusual carbon bonds. The structures of the compounds were determined using spectroscopy and X-ray crystallography. The screening results indicated that 1, 2, and 5 showed remarkable lipid-lowering activities in FFA-induced HepG2 cells, with EC50 values ranging from 3.13 to 6.57 μM. Moreover, 1, 2, and 5 significantly decreased both the mRNA and protein levels of the target SREBP-1c, and 5 also reduced PPARα mRNA and protein levels. Therefore, 1, 2, and 5 are potential drugs against hepatic steatosis by targeting PPARα or SREBP-1c.

Abstract
Eleven new amides, four racemic pairs of (±)-chlorahupetamides A, B, D, E (1, 2, 4, 5) and chlorahupetamides C, F, G (3, 6, 7), have been isolated from Chloranthus henryi var. hupehensis. Compounds 1-3 are the first naturally occurring dimers via an unprecedented [2 + 2] cycloaddition derived from two dissimilar cinnamic acid amides, while compounds 4 and 5 represent the first examples of lignanamides in Chloranthus; together with two new hydroxycinnamic acid amide monomers (6-7), these compounds were obtained. Their structures were characterized by nuclear magnetic resonance (NMR), electronic circular dichroism (ECD), and X-ray diffraction analysis. Meanwhile, an LPS-induced BV-2 cell inflammatory model was used to determine the potential anti-inflammatory activity of all the isolated compounds. Intriguingly, compound -1 treatment showed a much greater inhibition of TNF-α expression with an EC50 value of 1.80 µM, while compound + 1 had more advantages in reducing IL-1β expression with an EC50 value of 19.93 µM. Moreover, compounds + 1 and -1 could significantly suppress inflammation and inhibit the Akt signaling pathway by decreasing the phosphorylated protein levels of Akt.

Abstract
(+)- and (-)-Chlorahupetenes A (1a and 1b), B (2a and 2b), C (3a and 3b), and D (4a and 4b), four unique enantiomeric pairs of eudesmane-type sesquiterpenoid dimers with two new carbon skeletons, were isolated from the aerial parts of Chloranthus henryi var. hupehensis. Compounds 1 and 2 possess an unprecedented 6/6/5/6/6 pentacyclic carbon skeleton with a new dimerization pattern of two eudesmane-type sesquiterpenoids. Compounds 3 and 4, which are fused with two eudesmane-type sesquiterpenoids via an unprecedented five-membered O-heterocyclic ring, represent a new 6/6/5/5/6/6/5 heptacyclic ring system. The structures of the compounds were determined through spectroscopic data and X-ray crystallography. Compounds 1a-3b significantly inhibited NO production with IC50 values ranging from 9.62 to 12.91 μM. Moreover, compounds 1b and 3a suppressed the production of a proinflammatory mediator (TNF-α) and enzyme expression (iNOS) at the mRNA level.

Abstract
Objective: To analyze the characteristics of vocal fold vibration of normal people and patients with spasmodic dysphonia (SD) using laryngeal high speed videoendoscopy combined with glottal area wave analysis. Methods: This prospective study examined twenty healthy subjects (10 males and 10 females), 12 patients with adductor spasmodic dysphonia(AdSD) (2 males,10 females)as AdSD group and 2 patients with abductor spasmodic dysphonia(AbSD) (2 males) as AbSD group. Twelve of healthy subjects (2 males,10 females) were selected as control group according to AdSD group gender match. All the subjects were recruited from the Department of Voice, Zhongshan Hospital, Xiamen University from October 2019 to December 2020. All subjects underwent laryngeal high speed videoendoscopy and 10 vibration periods were selected from each recording and were used to quantitatively analyze the change of glottal area and vocal fold vibration parameters (Speed Quotient (SQ), Open Quotient (OQ) and Close Quotient (CQ)). Results: 1. There were statistically significant differences in SQ, CQ and OQ between males and females in the healthy subjects (t=12.28, 5.59, 5.59, P<0.05). The change of the glottal area during each vibration period in healthy subjects was relatively stable(0.19-0.42). 2. The change of the glottal area during each vibration period in AdSD subjects had larger fluctuations, with the glottal area change index fluctuating in the range of 0.31 to 0.62. The SQ value of the AdSD group was significantly lower than that of control group (t=4.246, P<0.05). There were no significant differences in OQ and CQ between AdSD group and normal group (t=1.064, 1.332, P>0.05); The SQ value of the AbSD group tended to increase compared to normal group. Conclusions: Laryngeal high speed videoendoscopy combined with glottal area wave analysis has a certain reference value in the studying the vibration characteristics of SD patients. SQ has good specificity.

Abstract
Objective: To explore the dynamic changes of three-dimensional morphology of laryngeal soft tissue and its clinical value in the unilateral vocal fold paralysis (UVFP) patients through dynamic CT scanning during the process from inspiration to phonation. Methods: From October 2017 to July 2019, a retrospective study was performed in 18 patients with UVFP (10 males and 8 females with the range of age from 29 to 75 years old) and 10 normal subjects (5 males and 5 females with the range of age from 25 to 58 years old) in Department of Voice-Otolaryngology Head and Neck Surgery, Section Two, Zhongshan Hospital Xiamen University. The laryngeal dynamic computed tomography (CT) of cine mode was performed. Ten dynamic sequence images of vocal folds movements were obtained during the process from inspiration to phonation. Based on the dynamic changes of glottic area and the displacement of cricoid cartilage. The above dynamic sequence images were divided into inspiratory phase and phonation phase as well as open phase and closed phase. The soft tissue parameters were measured respectively, including vocal folds length, width, thickness and subglottal convergence angle. Independent-sample t test was used to analyze between UVFP group and control group. Results: During the process from inspiration to phonation, the morphology of vocal folds in control group was relatively stable at inspiratory phase and closed phase in phonation. When open phase and closed phase of phonation were switching, the morphology of vocal folds changed obviously. The length of vocal folds became longer (1.19±0.10) mm, the width became wider (2.19±0.17) mm, the thickness became thinner (2.66±0.56) mm, and the subglottal convergence angle decreased (31.45±4.78)°. Compared with the controll group, in the open phase, the thickness and width of the vocal fold on affected side in the UVFP group were thinner (t=10.25, P<0.001) and wider (t=5.25, P<0.001).While in the closed phase, the subglottal convergence angle was larger (t=4.41, P=0.001).The width of the healthy side vocal fold in the UVFP was wider (t=2.54, P=0.026) than that in the control group. The differences in other parameters were not statistically significant. Conclusions: Dynamic laryngeal CT scanning provides a simple and non-invasive method for the objective and quantitative measurement of the dynamic changes of laryngeal morphology from inspiration to phonation. Compared with the control group, the characteristic dynamic changes among UVFP were observed during this particular process, which included changes of subglottal convergence angle and thickness of vocal muscle due to denervation. In addition, in UVFP group, the width of the vocal fold healthy side in the closed phase may be used to assess its compensatory function.

Methods: Six patients were selected with Ⅰor Ⅱ or Ⅲ degree of dyspnea diagnosed as bilateral recurrent laryngeal nerve injury by laryngeal electromyography, and small dose of botulinum toxin injection was performed in cricothyroid muscle and thyroarytenoid muscle as a treatment. Degree of dyspnea was assessed one month before and after the treatment, and the stroboscopic laryngoscope results, acoustic parameters and CT image of the patients were collected in the 6 patients. The relevant parameters were also collected one month before and after treatment, including the degree of dyspnea, stroboscopic laryngoscope results, acoustic parameters and CT image of the patients. The angle between bilateral vocal cords in stroboscopy at full inspiratory was calculated, acoustic parameters (F0, jitter, shimmer) were analysed, and vocal length, width and the vocal region were measured. Then, the paired t test was performed for statistical analysis between before and after one month injection, the one way analysis of variance was performed among vocal parameters in CT image. Result: Botulinum toxin injection was successfully completed in the 6 patients, followed without any serious complications. The degree of dyspnea was alleviated to some extent after treatment in all 6 patients; the angle between bilateral vocal cords at the end of a deep inspiration was significantly increased (t=2.44, P<0.05) after the treatment. The changes of F0 and jitter between before and after treatment were not statistically significant (t=0.72, t=1.42, P>0.05). Shimmer was significantly decreased after treatment (t=2.61, P<0.05). Vocal fold length, width and vocal region increased with F0, there was a statistically significant difference between different F0 before injection, and there was no statistically significant difference between different F0 after injection. The follow-up time was respectively seven months, 1 year, 1 year, 18 months, 22 months and 2 years respectively. Conclusion: Small dose of botulinum toxin injection in bilateral cricothyroid muscles and thyroarytenoid muscles can relieve the dyspnea caused by bilateral vocal cords paresis to some extent, accompanied without serious complications, despite the sound quality was slightly worse.

Abstract
Objective: To compare the acoustic signal, mucosal wave and aerodynamic parameter (phonation threshold pressure, PTP) under different sub-glottal pressure (SGP) on the excised canine models with different extent of glottal incompetence. Methods: Perturbation measures and nonlinear dynamic measures were applied to analyze the acoustic signal (jitter, shimmer), mucosal wave [frequency(F), amplitude(A), phase(P)] and PTP from our study including 11 excised canine larynges with different extent of glottal incompetence (0 mm, 1 mm, 2 mm, 3 mm, n=11, respectively) under 1-4 kPa sub-glottal pressure. Results: There were significant differences between different groups in jitter, shimmer, amplitude, frequency and PTP under various SGPs and extent of glottal incompetence (all P<0.05), inversely, there was no significant difference in P between groups (P>0.05). Jitter and shimmer changed obviously when the SGP increased to 3 kPa in the control group and GI 1 mm group. Jitter and shimmer changed obviously when the SGP increased to 2 kPa in the GI 2 mm and 3 mm groups. The F and A of mucosal wave increased with increasing SGP, decreased with increasing GI, and the P changed irregularly. There was statistically significant difference of PTP between different GI groups. Conclusions: The SGP and the extent of GI had obvious affection on the the acoustic signal, mucosal wave and aerodynamic parameters.

Abstract
Objective:Analysis of the sustained vowels of acoustic parameters in arytenoid dislocation and vocal fold paralysis. To investigate their acoustic characteristics and evaluate the role of this acoustic analysis method in differentiating arytenoid dislocation from vocal fold paralysis. Method:Thirty-three cases with unilateral vocal cord movement disorders were collected.All cases were divided into arytenoid dislocation group and vocal fold paralysis group through the laryngeal electromyography. Each group was further devided into male group and female group. The voice signals of sustained vowel of /a/ were measured using the software MDVP and obtain the acoustic parameters(Jitter, Shimmer, SPI and Fo). The acoustic characteristics between the two groups were observed and compared. Results were analyzed using Rank sum test for group design.Result:There were significant differences in Fo between arytenoid dislocation group and vocal fold paralysis group in both male and female group(P <0.05). And mean rank order of Fo in arytenoid dislocation group was greater than vocal fold paralysis group. There were no significant differences in jitter,shimmer and SPI between arytenoid dislocation group and vocal fold paralysis group(P >0.05).Conclusion:Mean rank order of Fo in arytenoid dislocation group is greater than vocal fold paralysis group in both the male and the female group. Fo is of value in differentiating arytenoid dislocation from vocal fold paralysis. This provides a theoretical basis for the acoustic analysis method to identify these two diseases.

Abstract
Eleven prenylated C(6)-C(3) compounds, illihenryifunones A, B (1, 2), illihenryifunol A (3), illihenryipyranol A (4), illihenryiones A-G (5-11), and three known prenylated C(6)-C(3) compounds (12-14), were isolated from the roots of Illicium henryi. Structures of 1-11 were elucidated by spectroscopic methods including NMR, HRESIMS, and CD. The absolute configuration of the 11,12-diol moiety in 5 was determined by observing its induced circular dichroism after addition of Mo(2)(OAc)(4) in DMSO. The absolute configuration of C-11 in 4 was determined as S based on the Rh(2)(OCOCF(3))(4)-induced CD data; the absolute configuration of 3 was determined as R by comparison of its experimental and calculated electronic circular dichroism (ECD). The antioxidant activities of compounds 1-14 were also evaluated. Compound 4 exhibited strong antioxidant activity with an IC(50) value of 2.97±1.30 μM, whereas compounds 3 and 8 showed antioxidant activities with IC(50) values of 44.36±0.30 and 48.00±2.01 μM, respectively.
