Abstract
Increasing evidence has demonstrated that glutaminase (GLS) as a key mitochondrial enzyme plays a pivotal role in glutaminolysis, which widely participates in glutamine metabolism serving as main energy sources and building blocks for tumor growth. However, the roles and molecular mechanisms of GLS in esophageal squamous cell carcinoma (ESCC) remains unknown. Here, we found that GLS was highly expressed in ESCC tissues and cells. GLS inhibitor CB-839 significantly suppressed cell proliferation, colony formation, migration and invasion of ESCC cells, whereas GLS overexpression displayed the opposite effects. In addition, CB-839 markedly suppressed glucose consumption and lactate production, coupled with the downregulation of glycolysis-related proteins HK2, PFKM, PKM2 and LDHA, whereas GLS overexpression exhibited the adverse results. In vivo animal experiment revealed that CB-839 dramatically suppressed tumor growth, whereas GLS overexpression promoted tumor growth in ESCC cells xenografted nude mice. Mechanistically, GLS was localized in mitochondria of ESCC cells, which interacted with PDK1 protein. CB-839 attenuated the interaction of GLS and PDK1 in ESCC cells by suppressing PDK1 expression, which further evoked the downregulation of p-PDHA1 (s293), however, GLS overexpression markedly enhanced the level of p-PDHA1 (s293). These findings suggest that interaction of GLS with PDK1 accelerates the glycolysis of ESCC cells by inactivating PDH enzyme, and thus targeting GLS may be a novel therapeutic approach for ESCC patients.

Abstract
The temporomandibular joint (TMJ) disc is mainly composed of collagen, with its arrangement responding to efficient stress distribution. However, microstructural and micromechanical transformations of the TMJ disc under resting, functional, and pathological conditions remain unclear. To address this, our study presents a high-resolution microstructural and mechanical atlas of the porcine TMJ disc. First, the naive microstructure and mechanical properties were investigated in porcine TMJ discs (resting and functional conditions). Subsequently, the perforation and tear models (pathological conditions) were compared. Following this, a rabbit model of anterior disc displacement (abnormal stress) was studied. Results show diverse microstructures and mechanical properties at the nanometer to micrometer scale. In the functional state, gradual unfolding of the crimping cycle in secondary and tertiary structures leads to D-cycle prolongation in the primary structure, causing tissue failure. Pathological conditions lead to stress concentration near the injury site due to collagen interfibrillar traffic patterns, resulting in earlier damage manifestation. Additionally, the abnormal stress model shows collagen damage initiating at the primary structure and extending to the superstructure over time. These findings highlight collagen's various roles in different pathophysiological states. Our study offers valuable insights into TMJ disc function and dysfunction, aiding the development of diagnostic and therapeutic strategies for TMJ disorders, as well as providing guidance for the design of structural biomimetic materials.

Abstract
Hydrogel electrolyte can endow supercapacitors with excellent flexibility, which has developed rapidly in recent years. However, the water-rich structures of hydrogel electrolyte are easy to freeze at subfreezing and dry at high temperatures, which will affect its energy storage characteristics. The low energy density of micro supercapacitors also hinders their development. Herein, a strategy is proposed to reduce the free water activity in the hydrogel to improve the operating voltage and the energy density of the device, which is achieved through the synergistic effect of the hydrogel skeleton, N, N'-dimethylformamide (DMF), NaClO4 and water. High concentrations of DMF and NaClO4 are introduced into sodium alginate/polyacrylamide (SA/PAAM) hydrogel through solvent exchange to obtain SA/PAAM/DMF/NaClO4 hydrogel electrolyte, which exhibited a high ionic conductivity of 82.1 mS cm-1, a high breaking strength of 563.2 kPa, and a wide voltage stability window of 3.5 V. The supercapacitor devices are assembled by the process of direct adhesion of the hydrogel electrolyte and laser induced graphene (LIG). The micro-supercapacitor exhibited an operating voltage of 2.0 V, with a specific capacitance of 2.41 mF cm-2 and a high energy density of 1.34 µWh cm-2, and it also exhibit a high cycle stability, good flexibility, and integration performance.

Abstract
Objective: To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap. Methods: A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis. Results: All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] (P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant (P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively (P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion: For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

Abstract
We measured the nuclear-recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from a monoenergetic beam scatter off of the silicon nuclei at angles corresponding to energy depositions from 4 keV down to 100 eV, the lowest energy probed so far. The results show no sign of an ionization production threshold above 100 eV. These results call for further investigation of the ionization yield theory and a comprehensive determination of the detector response function at energies below the keV scale.

Abstract
Objective: To evaluate the auditory efficacy and subjective satisfaction of adhesive bone conduction hearing aid in children with unilateral congenital aural atresia (UCAA). Methods: Ten subjects (5 males and 5 females) diagnosed with UCAA with an average age of 8.3 years old (ranged from 5 to 15) were included in Beijing Tongren Hospital, Capital Medical University from January to August 2019. The free sound field hearing threshold, word recognition score in quiet, speech reception threshold in noise and sound localization ability (results were measured by RMS error) tests were performed in unaided and aided situation, respectively. Subjective satisfaction questionnaires were also distributed to subjects. Paired t test and Wilcoxon signed rank test were used as statistical analysis methods. Results: The average hearing threshold in aided condition was improved by (21.9±4.4) dB (t=15.8,P<0.05). Speech recognition abilities were generally improved both under quiet and noise (P<0.05);however, when the binaural summation, squelch and head shadow effects were analyzed respectively, the binaural squelch effect was not statistically improved (P>0.05), while the other effects were improved in aided condition (P<0.05). In sound localization test, there was no significant difference of the RMS error value between the unaided and aided situation (P>0.05). The subjects got high satisfaction rates in three subjective questionnaires. Conclusion: The adhesive bone conduction hearing aid can provide significant audiological benefit for children with UCAA as well as raising the quality of their life.

Abstract
The Cryogenic Dark Matter Search low ionization threshold experiment (CDMSlite) achieved efficient detection of very small recoil energies in its germanium target, resulting in sensitivity to lightly ionizing particles (LIPs) in a previously unexplored region of charge, mass, and velocity parameter space. We report first direct-detection limits calculated using the optimum interval method on the vertical intensity of cosmogenically produced LIPs with an electric charge smaller than e/(3×10^{5}), as well as the strongest limits for charge ≤e/160, with a minimum vertical intensity of 1.36×10^{-7} cm^{-2} s^{-1} sr^{-1} at charge e/160. These results apply over a wide range of LIP masses (5 MeV/c^{2} to 100 TeV/c^{2}) and cover a wide range of βγ values (0.1-10^{6}), thus excluding nonrelativistic LIPs with βγ as small as 0.1 for the first time.

Abstract
We present limits on spin-independent dark matter-nucleon interactions using a 10.6 g Si athermal phonon detector with a baseline energy resolution of σ_{E}=3.86±0.04(stat)_{-0.00}^{+0.19}(syst) eV. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses from 93 to 140 MeV/c^{2}, with a raw exposure of 9.9 g d acquired at an above-ground facility. This work illustrates the scientific potential of detectors with athermal phonon sensors with eV-scale energy resolution for future dark matter searches.

Abstract
This study aimed to investigate the roles of hsa_circRNA_103801 in the progression of osteosarcoma (OS) cells. Quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to detect the expression level of circRNA_103801 in OS cells. Cell count kit-8 and Transwell migration and invasion assays were employed to detect the proliferation, migration, and invasion abilities of OS cells. The effects of circRNA_103801 on the apoptosis of OS cells were identified by flow cytometry. The binding relationship between circRNA_103801 and miR-338-3p was verified by bioinformatics analysis. MiR-338-3p level in OS cell lines was detected by RT-qPCR. Additionally, Western blotting was utilized to detect the expression levels of HIF-1, Rap1, PI3K, and Akt in OS cells. The results showed that the expression level of circRNA_103801 was significantly up-regulated in OS patients' tissues. Inhibiting the expression level of circRNA_103801 could attenuate the proliferation, migration, and invasion abilities of OS cells. In addition, the down-regulated expression level of circRNA_103801 could induce cell apoptosis. The results of the luciferase reporter assay suggested that circRNA_103801 could be combined with miR-338-3p, and the RT-qPCR revealed that the miR-338-3p level in OS cells after knockdown of circRNA_103801 was elevated compared with the control group. The results of Western blotting suggested that the expression levels of HIF-1, Rap1, PI3K, and Akt were elevated in OS cells. In conclusion, the circRNA_103801-miR-3388-3p-HIF-1/Rap1/PI3K-Akt pathway could be a therapeutic target of OS.

Abstract
In this study, the microbial interactions among cocultures of Streptococcus thermophilus (St) with potential probiotics of Bifidobacterium animalis ssp. lactis (Ba) and Lactiplantibacillus plantarum (Lp) in fermented milk were investigated during a storage period of 21 d at 4°C, in terms of acidifying activity (pH and titratable acidity), viable counts, and metabolites. A nontargeted metabolomics approach based on ultra-high-performance liquid chromatography coupled with mass spectrometry was employed for mapping the global metabolite profiles of fermented milk. Probiotic strains cocultured with St accelerated milk acidification, and improved the microbial viability compared with the single culture of St. The St-Ba/Lp treatment manifested a higher bacteria viability and acidification ability in comparison with the St-Ba or the St-Lp treatment. Relative quantitation of 179 significant metabolites was identified, including nucleosides, AA, short peptides, organic acids, lipid derivatives, carbohydrates, carbonyl compounds, and compounds related to energy metabolism. The principal component analysis indicated that St treatment and coculture treatments displayed a complete distinction in metabolite profiles, and Lp had a larger effect than Ba on metabolic profiles of fermented milk produced by cofermentation with St during storage. The heat map in combination with hierarchical cluster analysis showed that the abundance of metabolites significantly varied with the starter cultures over the storage, and high abundance of metabolites was observed in either St or coculture samples. The St-Ba/Lp treatment showed relatively high abundance for the vast majority of metabolites. These findings suggest that the profile of the metabolites characterizing fermented milk samples may depend on the starter cultures, and incorporation of probiotics may considerably influence the metabolomic activities of fermented milks.

Abstract
Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Abstract
The efficient treatment of high stability emulsion with small diameter and the prevention of oil contamination of materials are serious issues in the process of emulsion separation. In order to address those issues, we reported a fast and versatile hydrophilic surface coating technology that uses oxidants and diamines to synergistically promote the polymerization of caffeic acid (CA). It was found that amino groups can not only accelerate the polymerization of CA, but also promote the deposition of polymers on the sponge surface. Using silica nanoparticles to improve the roughness, superhydrophilic melamine sponge could be prepared, which exhibited excellent superhydrophlic-underwater superolephobic and anti-oil-adhesion properties. DFT simulation was employed to explore the potential mechanism of the anti-oil adhesion ability. In addition, combined with the mechanical compression strategy, the sponge exhibited a high efficiency of 99.10% with a permeation flux of 19080 ± 700 Lm-2 h-1 in emulsion separation just under the action of gravity. Moreover, based on the interaction between the surfactant and the surface of the material, the separation mechanism was discussed. Overall, this work provided an advanced method for the preparation of superhydrophilic sponge with anti-oil-fouling performance, which showed great potential in dealing with practically challenging emulsified wastewater.

Abstract
Objective: To explore the CT imaging features of the 2019 novel coronavirus (2019-nCoV) infection in order to summarize the imaging characteristics of the disease and improve the ability of imaging diagnosis and early diagnosis of the disease. Methods: From January 13, 2020 to January 31, 2020, a total of 33 patients with 2019-nCoV infection diagnosed and treated by Suzhou Fifth People's Hospital were analyzed retrospectively, including 20 males and 13 females, with an average age of (50±12) years, ranging from 20 to 70 years old. There were 3 cases of mild type, 27 cases of common type and 3 cases of severe type.There were 2 cases with hypertension, 1 case with postoperative lung,1 case with diabetes, 1 case with chronic bronchitis, and 1 case with bronchiectasis.SPSS25.0 Chi-square test was used to analyze the distribution of lesions in each lung lobe; SPSS25.0 Spearman correlation coefficient was used to analyze the image score and clinical classification. Results: There were 3 cases (9.1%) with normal lung and 30 cases (90.9%) with Novel Coronavirus Pneumonia(COVID-19) of the 2019-nCoV infected patients. In the distribution of COVID-19, 29 cases (87.9%) were involved in bilateral lung and 1 case (3.0%) in unilateral lung. There was no statistically significant difference in the distribution of lesions in each lobe. The correlation coefficient between the degree of lesion distribution and clinical classification was 0.819, and the two were highly correlated.There were 30 cases (90.9%) with subpleural lesions, 17 cases (51.5%) with central lesions. There were many kinds of lesions, 25 cases (75.8%) had ground glass density shadow, 16 cases (48.5%) had consolidation, 12 cases (36.4%) had interstitial change, and 18 cases (54.5%) had interlobular septal thickening. Among the 22 cases, 10 cases had more lesions, 6 cases had no changes and 6 cases had less lesions. Conclusion: Most of the patients with 2019-nCoV infection have pulmonary inflammation.CT manifestations include multiple parts, subpleural area or middle and lateral field of lung, ground glass shadow and consolidation, or coexistence. Some cases have pleural thickening or interlobular septal thickening. CT images can indicate the diagnosis of COVID-19 and provide important basis for early detection and disease monitoring.

Abstract
In order to achieve the purpose of simultaneous removal of coexisting heavy metal ions, in this work, functionalized magnetic mesoprous nanomaterials (Fe3O4-HBPA-ASA) with high density and multiple adsorption sites were designed and prepared. The obtained Fe3O4-HBPA-ASA was characterized by SEM, FTIR, VSM, TGA and zeta potential. Cu(II), Pb(II) and Cd(II) were chosen as the model heavy metal ions, the adsorption experiments showed that Fe3O4-HBPA-ASA showed hightheoretical adsorption capacitiesin individual system, and the maximum adsorption capacity was 136.66 mg/g, 88.36 mg/g and 165.46 mg/g, respectively. In the binary and ternary systems, the competitive adsorption leads to a decrease in the adsorption capacity of Cu(II), Pb(II) and Cd(II). However, in the ternary system with a concentration lower than 15 mg/L, the simultaneous removal rate was still higher than 90%. The adsorption isotherms and kineticswere well fitted by Langmuir and pseudo-second-order models, respectively. The XPS and density functional theory (DFT) analysis have confirmed that the adsorption of metal ions was related to various types of functional groups on the surface of Fe3O4-HBPA-ASA, while the adsorption mechanisms of Cu(II), Cd(II) and Pb(II) were different.

Abstract
Objective: To explore the natural course of obstructive sleep apnea-hypopnea syndrome (OSAHS) and its associated factors in young and middle-aged patients with OSAHS. Methods: A total of 52 young and middle-aged OSAHS patients were recruited in this study from West China Hospital of Sichuan University. All patients were performed twice overnight polysomnography (PSG) examinations. At the baseline, patients underwent the first PSG and clinical evaluation from September 2009 to September 2017 and the patients received the second PSG from January 2017 to January 2019. During the follow-up period, these patients had no treatment. All patients were categorized into two groups including mild-to-moderate [5/h≤ apnea-hypopnea index (AHI)<30/h] group and severe (AHI ≥ 30/h) group according to the baseline AHI value. Differences in the clinical characteristics and PSG variables between baseline and follow-up were compared in two groups separately using t-tests or Mann-Whitney U test. The general linear correlation analysis was used to explore the factors related to the severity of OSAHS including AHI, the mean oxyhemoglobin saturation and the minimal oxyhemoglobin saturation during the follow-up period. Results: This study recruited 28 OSAHS patients in mild-to-moderate group [mean age, (39.7±10.2) y] and 24 patients in severe group [mean age, (41.0±7.1) y]. Compared to the baseline, there was a significant increase in AHI value [(45.0±25.3) vs (33.6±27.3)/h, P<0.001] in all OSAHS patients. Notably, the increase of AHI was more significant in the mild-to-moderate OSAHS group [(32.1±22.2) vs (13.6±8.7)/h, P<0.05] but not in severe OSAHS patients [(60.7±19.5) vs (58.0±21.5)/h, P>0.05]. A person correlation analysis revealed that the AHI value was positively related to the age (r=0.531, P=0.004) in mild-to-moderate OSAHS patients. Conclusion: The severity of OSAHS is increased with the age in young and middle-aged patients with mild-to-moderate OSAHS, but not in those with severe OSAHS.

Abstract
Objective: To examine the association between objective sleepiness and neurocognitive function before and after continuous positive airway pressure (CPAP) in obstructive sleep apnea (OSA) patients. Methods: A total of 53 patients with overnight polysomnography (PSG) determined moderate-to-severe OSA (apnea hypopnea index (AHI) ≥15 events/h) and with overnight CPAP therapy from West China Hospital, Sichuan University within the period from Feb 2018 to Dec 2018 were enrolled in the study. At the baseline, all patients underwent overnight PSG study, multiple sleep latency test (MSLT), psychomotor vigilance test (PVT), and Epworth sleepiness score (ESS). After CPAP therapy, all patients underwent MSLT and PVT. Paired nonparametric test or t test were used to compare the differences between daytime sleepiness and PVT performance before and after CPAP. Results: Compared with baseline data, AHI [68.8(42.2, 80.0) vs 7.4(3.1, 11.1) events/h, P<0.05] decreased, the percentages of non-rapid eye movement stage 3 sleep time [0(0, 0.5%) vs 4.4%(1.9%, 11.3%), P<0.05] and the percentages of rapid eye movement sleep time [18.6%(13.2%, 22.7%) vs 25.4%(23.85, 30.3%), P<0.05] increased after CPAP therapy. The reaction time (RT) [353.0(317.5, 429.5) vs 333.6(309.7, 381.4) ms, P<0.05], the slowest 10% RT [602.9(473.2, 841.3) vs 505.5(431.6, 618.8) ms, P<0.05] and the fastest 10% RT [260.8(236.6, 300.6) vs 251.4(233.6, 283.2) ms, P<0.05] shortened, and the lapse [6.0(2.5, 16.5) vs 3.0(1.0, 8.5) events, P<0.05] decreased. The mean sleep latency (MSL) [5.8 (3.4, 8.3) vs 7.5(4.7, 12.4) min, P<0.05] increased. The changes in PVT parameters [ΔRT (r=0.20, P>0.05), Δslowest 10% RT (r=0.15, P>0.05), Δfastest 10% RT (r=0.24, P>0.05), and Δlapse (r=0.15, P>0.05)] were not correlated with the change in MSL. The significant association between the slowest 10% RT and ESS was found in baseline data. Conclusions: The change in MSL is not associated with the change in PVT performance before and after CPAP therapy. MSLT and PVT may be different in nature.

Abstract
Objective: To examine the association between mixed sleep apnea (MA) and treatment-emergent central sleep apnea (TE-CSA). Methods: A total of 256 patients meeting the diagnostic criteria of moderate to severe obstructive sleep apnea (OSA) based on overnight polysomnography (PSG) and receiving continuous positive airway pressure (CPAP) therapy in West China Hospital, Sichuan University during the period from August 2013 to November 2018 were enrolled in the study. Based on the mixed apnea index (MAI) and apnea-hypopnea index (AHI) in the baseline PSG study during non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep, the subjects were categorized into three groups of A (MAI=0/h, n=110), B (NREM-MAI≥5/h and REM-MAI<5/h, n=72) and C (REM-MAI≥5/h and NREM-MAI< 5/h, n=74). Sleep and breathing related parameters before and after CPAP therapy among three groups and the difference of TE-CSA incidence were analyzed. Results: The AHI [(44.2(26.8,64.5)/h,66.6(56.0,81.7)/h, 79.8(63.6, 88.3)/h], REM-AHI [50.0(34.7, 64.7)/h, 60.1(49.1, 70.0)/h, 66.3(56.1, 74.6)/h] and NREM-AHI[43.5(25.9, 65.1)/h,67.6(53.7, 82.4)/h,81.3(64.2, 91.5)/h]) were higher in group B and C compared to group A (all P<0.05),while the mean and lowest oxygen saturation [(92.6%±3.5%),(90.8%±3.6%),(87.3%±5.1%) and (70.6%±14.1%), (61.0%±16.0%), (47.9%±17.0%)] were lower in group B and group C compared to group A (all P<0.05). The incidence of TE-CSA after initial CPAP was 7.8% in all patients, and the incidence was significantly higher in group B of 14.1% compared to group C of 4.1% and group A of 2.7% (all P<0.05). Conclusions: TE-CSA is correlated with baseline MA, and baseline MA in NREM sleep can predict the incidence of TE-CSA after initial CPAP.

Abstract
BACKGROUND miR-138 is one of the down-regulated miRNAs during acute spinal cord injury. Mixed lineage kinase 3 (MLK3), a key factor of jun N-terminal kinase (JNK)/mitogen-activated protein kinase (MAPK) pathway, is the target of miR-138. The aim of this study was to investigate the role of miR-138 in H2O2-treated BV-2 cells. METHODS Murine microglia BV-2 cells were treated with H2O2 and tested for cell viability and miR-138 expression. The cells were then transfected with miR-138 agomir or miR-138 antagomir, and treated with 200 μM H2O2 for 24 h. The cellular apoptosis was detected by Aennexin V/PI staining. Expression of miR-138, MLK3, and other factors of JNK/MAPK pathway was detected. RESULTS After treatment of various concentrations of H2O2, the cell viabilities were reduced, and miR-138 expression was down-regulated. Compared to the control cells, over-expressing miR-138 in BV-2 cells reduced apoptosis rate from 24.2 % to 11.9 %. Western blot further showed that JNK, p-JNK, c-jun, p-c-jun, p38 MAPK, and p-p38 MAPK were down-regulated. Expression of pro-apoptosis factors iNOS and COX-2 were also down-regulated. Transfection of miR-138 antagomir produced the opposite effect of the transfection of miR-138 agomir. CONCLUSION miR-138 was able to reduce H2O2-induced apoptosis in BV-2 cells. The protective effect was related to the down-regulation of MLK3 proteins and sequentially inhibiting JNK/MAPK signaling pathway (Fig. 3, Ref. 27). Text in PDF www.elis.sk.

Abstract
Objective: To investigate the effects of continuous positive airway pressure (CPAP) on periodic limb movements during sleep (PLMS) in patients with obstructive sleep apnea (OSA). Methods: The polysomnography (PSG) data of 828 consecutive OSA outpatients from January 2015 to January 2017 who had undergone overnight CPAP titration were analyzed retrospectively. On the basis of changes in periodic limb movements index (PLMI) values (cut off level≥15/h) from baseline PSG (BPSG) to CPAP titration PSG, patients were assigned to one of the following four groups: persistent, CPAP-emergent, CPAP-disappeared, and non-PLMS. Results: Among 828 patients, 756 (91.3%) were male and 72 (8.7%) were female. The mean age was (45.7±10.7) years old, the mean body mass index (BMI) was (27.6±3.5) kg/m(2). The rate of patients was 3.9% in the persistent group, 10.3% in the CPAP-emergent group, 7.5% in the CPAP-disappearance group, and 78.4% in the non-PLMS group. Multivariate Logistic regression analysis revealed that female appeared to be associated with the persistent group (P=0.004); older age and higher apnea-hypopnea index (AHI) on BPSG appeared to be associated with the CPAP-emergent group (P=0.012, 0.030). On the other hand, older age was negatively associated with the non-PLMS group (P=0.006). Conclusion: Elderly patients with higher AHI at BPSG may present with CPAP-emergent PLMS.

Abstract
Objective: To explore the gender differences of rapid-eye-movement (REM) related obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: Consecutive patients with primary complaint of snoring from Sleep Medicine Center of West China Hospital between January 2016 and November 2016 were included in the study. All participants underwent one night polysomnography (PSG) and Epworth sleep scale (ESS) was estimated. The patients diagnosed with OSAHS were classified as REM related OSAHS (REM-OSAHS group) and non-rapid-eye-movement (NREM) related OSAHS (NREM-OSAHS group) based on the PSG parameters. And the gender differences of demographic and polysomnograpic characteristics in both groups were compared. The associations between apnea-hypopnea index (AHI) and body mass index (BMI), neck circumference and waist circumference among patients with OSAHS were explored by multiple linear regression analysis. Results: A total of 1 258 patients were diagnosed with OSAHS. There were 997 (79.3%) male and 261 (20.7%) female among these patients, the mean age was (46.4±12.0) years old and mean BMI was (26.6±3.4) kg/m(2). There were 236 patients (18.8%) classified into REM-OSAHS group, and 1 022 patients (81.2%) classified into NREM-OSAHS group; the proportion of REM-OSAHS in female was significantly higher than that in male (34.1% vs 14.7%, P<0.001). After controlling for age, drinking, smoking, hypnotics, coffee, strong tea and sleep related parameters, in NREM-OSAHS group, AHI was positively correlated with BMI, neck circumference and waist circumference (P<0.001) both in male and female. In REM-OSAHS group, AHI was positively correlated with BMI, neck circumference and waist circumference in female (P<0.05), but only significantly correlated with BMI and waist circumference in male (P<0.05). Conclusions: REM-OSAHS is commonly seen in female OSAHS patients. Evaluation of the influences of anthropometric data on the severity of REM-OSAHS should consider the impact of gender.

Abstract
A simple and robust technique for directly measuring the loop gain and bandwidth of a phase-locked loop (PLL) is proposed. This technique can be used for the real-time measurement of the real loop gain in a closed PLL without breaking its locking state. The agreement of the measured loop gain and theoretical calculations proves the validity of the proposed measurement technique. This technique with a simple configuration can be easily expanded to other phase-locking systems whose loop gain and bandwidth should be measured precisely.

Abstract
Objective: To evaluate the auditory efficacy of Bonebridge implantation in patients with bilateral congenital malformation of external and middle ear. Methods: Eleven cases (6 males and 5 females) had unilateral Bonebridge implantation. The age ranged from 8 to 26 and the average age was 16.9. Seven to ten days after operation, the first fitting was undergone. In acoustic sound field, the average auditory thresholds were respectively measured for unaided ears and Bonebridge implanted ears by pure tone auditory (PTA, 0.25, 0.5, 1, 2 and 4 kHz). For the group over 12-year-old, MSTM was applied to evaluate speech discrimination score (SDS). For the other cases, MLNT was used as the test material. The auditory efficacy post Bonebridge implantation would be analyzed and evaluated by comparing the differences between unaided ears and Bonebridge implanted ears. Results: The bone conduction audibility threshold after Bonebridge implantation was as well as the preoperative. The auditory threshold with Bonebridge aided was improved to 25-35 dB HL, when compared to that of the unaided ears in the sound field. The SDS in the group over 12-year-old was improved about 50%; the efficacy was slightly limited for the other two cases (both less than 12 years old). Statistical analysis showed that there were significant differences between unaided ears and Bonebridge implanted ears in the sound field and SDS(P<0.05). Conclusions: The auditory efficacy of Bonebridge is significant and noticeable in patients with bilateral congenital malformation of external and middle ear. Bonebridge provides a new and effective way for patient with congenital malformation of external and middle ear to reconstruct hearing.

Objective:To investigate the surgical effects of round window implantation of vibrant soundbridge(VSB)for patients with congenital oval window atresia.Method:Retrospectively analyze the clinical information of 9 cases of congenital oval window atresia as well as the pre-and post-operative hearing and speech results. Three of them had undergone or attempted the vestibulotomy but obtained poor results. All cases underwent round window implantation of VSB. Result:All patients obtained an improvement of 21-33 dBHL after implantation. In the speech recognition rate test, the average increase of disyllabic words was 62%, and 60% in the sentence test. During the follow-up of 51 months in average, 2 cases had a decline of auditory benefit and finally 1 case regained the improvement after reoperation. Conclusion:Round window implantation can get a fairly good result in congenital oval windows atresia cases.

Abstract
Objective: To examine the association between subjective sleepiness and objective sleepiness in Chinese obstructive sleep apnea hypopnea syndrome (OSAHS) patients. Methods: A total of 1 660 patients meeting the diagnostic criteria of OSAHS based on overnight polysomnography from West China Hospital, Sichuan University in the period from Jul 2010 to Jul 2014 were enrolled in the study. The Epworth Sleepiness Scale (ESS) and Multiple Sleep Latency Test (MSLT) were to evaluate subjective and objective sleepiness, respectively. The subjects were categorized into quartiles [A (0-4) (n=406), B (5-7) (n=325), C (8-12) (n=443), D(13-24) (n=486) groups] based on the ESS score distribution. Survival analysis was used to characterize the association between the ESS score and the mean sleep latency (MSL). Results: The apnea hypopnea index (AHI) in D group was higher than other three groups [(58.7±26.1) vs (36.8±24.2), (42.6±26.7), (45.7±26.6) events/h, all P<0.05]. The mean sleep latency in D group was shorter than other three groups [(8.0±4.6) vs (10.9±4.4), (10.3±4.8), (9.4±4.5) min, all P<0.05]. The Kaplan-Meier survivor functions across the ESS score quartiles were distinct and fourth quartiles were progressively associated with a greater tendency for falling asleep (χ(2)=77.76, P<0.001 by Log-rank test) in the daytime (The percentages of awaking patients in fourth quartiles were progressively lower at the same time). The adjusted hazard ratios for sleep onset during the MSLT for the group B, C and D were 1.05 (95%CI: 0.90-1.22), 1.22 (95%CI: 1.07-1.40), and 1.38 (95%CI: 1.20-1.60), respectively, comparing to group A. Conclusion: Subjective report of daytime sleepiness is consistent with the objective sleepiness in OSAHS patients.

Abstract
Soybean mosaic virus (SMV), belonging to the genus Potyvirus of the family Potyviridae, has a relatively narrow host range almost exclusively confined to leguminous hosts. While disease management through genetic transformation can be an effective approach, soybean remains recalcitrant to routine genetic transformation. In this context, it is important to identify new hosts for SMV that can be used to develop effective transgenic resistance strategies. Transformation in Nicotiana benthamiana is simple and highly efficient; hence, here we demonstrate the infectivity of SMV strain SC7 in N. benthamiana plants. To identify an SMV strain infectious in N. benthamiana, we mechanically inoculated N. benthamiana plants with 37 isolates from 21 (SC1 to SC21) SMV strains. Plants inoculated with isolates of strain SC7 produced mosaic symptoms on leaves. However, N. benthamiana plants inoculated with the 20 other SMV strains showed no visible symptoms. Furthermore, soybean cv. Nannong 1138-2 inoculated with sap prepared from symptomatic N. benthamiana leaves showed typical SMV mosaic symptoms 2 weeks after inoculation. In addition, SMV was detected in symptomatic N. benthamiana and soybean leaves by RT-PCR, DAS-ELISA, and further identified by sequencing. Together, the results indicate that N. benthamiana plants could support multiplication of SMV strain SC7. The findings of this study would be useful for the investigation of SMV resistance using the model plant N. benthamiana.
