Abstract
The dynamic modification of RNA plays a crucial role in biological regulation and is strongly linked to human disease development and progression. Notably, modified nucleosides in urine have shown promising potential as early diagnostic biomarkers for various conditions. In this study, we developed and validated a rapid, sensitive, and accurate UPLC-MS/MS method for quantifying eight types of modified nucleosides (N1-methyladenosine (m1A), N6-methyladenosine (m6A), 5-methyluridine (m5U), 5-taurinomethyl-2-thiouridine (τm5s2U), 5-methylcytidine (m5C), 2'-O-methylcytidine (Cm), N1-methylguanosine (m1G), and N7-methylguanosine (m7G) in human urine. Using the method, we measured the urinary concentrations of m1A, m6A, m5U, τm5s2U, m5C, Cm, m1G, and m7G in a total of 21 control individuals and 23 patients diagnosed with diabetic retinopathy (DR). Cm levels showed promise as a diagnostic marker for diabetic retinopathy (DR), with a significant value (P < 0.01) and an AUC of 0.735. Other modified nucleosides also exhibited significant differences within specific subpopulations. As non-proliferative diabetic retinopathy (NPDR) signifies the latent early stage of diabetic retinopathy, we developed a multivariate linear model that integrates patients' sex, age, height, and urinary concentration of modified nucleosides which aims to predict and differentiate between healthy individuals, NPDR patients, and proliferative diabetic retinopathy (PDR) patients. Encouragingly, the model achieved satisfactory accuracy rates: healthy (81%), NPDR (75%), and PDR (80%). Our findings provide valuable insights into the development of an early, cost-effective, and noninvasive diagnostic approach for diabetic retinopathy.

Abstract
BACKGROUND Population aging might increase the prevalence of undernutrition in older people, which increases the risk of frailty. Numerous studies have indicated that myokines are released by skeletal myocytes in response to muscular contractions and might be associated with frailty. This study aimed to evaluate whether myokines are biomarkers of frailty in older inpatients with undernutrition. METHODS The frailty biomarkers were extracted from the Gene Expression Omnibus and Genecards datasets. Relevant myokines and health-related variables were assessed in 55 inpatients aged ≥ 65 years from the Peking Union Medical College Hospital prospective longitudinal frailty study. Serum was prepared for enzyme-linked immunosorbent assay using the appropriate kits. Correlations between biomarkers and frailty status were calculated by Spearman's correlation analysis. Multiple linear regression was performed to investigate the association between factors and frailty scores. RESULTS The prevalence of frailty was 13.21%. The bioinformatics analysis indicated that leptin, adenosine 5'-monophosphate-activated protein kinase (AMPK), irisin, decorin, and myostatin were potential biomarkers of frailty. The frailty group had significantly higher concentrations of leptin, AMPK, and MSTN than the robust group (p < 0.05). AMPK was significantly positively correlated with frailty (p < 0.05). The pre-frailty and frailty groups had significantly lower concentrations of irisin than the robust group (p < 0.05), whereas the DCN concentration did not differ among the groups. Multiple linear regression suggested that the 15 factors influencing the coefficients of association, the top 50% were the ADL score, MNA-SF score, serum albumin concentration, urination function, hearing function, leptin concentration, GDS-15 score, and MSTN concentration. CONCLUSIONS Proinflammatory myokines, particularly leptin, myostatin, and AMPK, negatively affect muscle mass and strength in older adults. ADL and nutritional status play major roles in the development of frailty. Our results confirm that identification of frailty relies upon clinical variables, myokine concentrations, and functional parameters, which might enable the identification and monitoring of frailty.

Abstract
Humic acids (HA) are a popular soil additive to reduce metal availability, but they have the drawbacks of reduced effectiveness over time and a significant reduction in soil pH. An alkaline humic acid fertilizer (AHAF) combining alkaline additives with HA was developed to overcome such drawbacks. A field experiment was conducted to investigate the effects of different AHAF application rates on the physicochemical properties, bioavailability, accumulation, and translocation of Cd and Zn heavy metals in Sauropus androgynus grown in acidic soil. Based on our results, the 100AF (100% AHAF) treatment significantly increased soil pH, cation exchange capacity (CEC), and organic matter content (OM) after one year of application. Compared with the control treatment (CK), the application of different rates of AHAF resulted in a 37.1-40.3% decrease in soil exchangeable Cd fractions (Exc-Cd) and an increase in the humic acid-bound Cd fractions (HA-Cd) Fe- and Mn-oxide-bound Cd fractions (OX-Cd), and organic matter-bound Cd fractions (OM-Cd) by 9.5-64.6%, 24.8-45.1%, and 158.8-191.2%, respectively (P < 0.05). The different AHAF treatments decreased the Res-Zn, Exc-Zn, and OM-Zn fractions by 69.6-73.0%, 7.4-23.9%, and 18.1-23.2%, respectively (P < 0.05), and increased the HA-Zn fraction by 8.4-28.1%. In the control treatment, the bioconcentration factors (BCFs) for Cd and Zn in different S. androgynus plant organs were in the following order: (Cd) Leaves > Stems > Branches > Roots > Edible branches; (Zn) Roots > Stems > Leaves > Branches > Edible branches. The transfer factors (TFs) of Cd and Zn in S. androgynus were classified as follows: TF2 > TF1 > TF3 > TF4. Thus, S. androgynus stems, and roots had a strong ability to transport Cd and Zn to the leaves. Compared with CK, the 100AF treatment significantly increased the BCFs for Zn in all plant parts (except BCFedible branches). In contrast, it significantly decreased all BCFs and TFs for Cd and the TF4 for Zn, effectively reducing Cd and Zn accumulation in the edible branches of S. androgynus. Soil pH, CEC, OM, and HA-M fraction were highly and significantly negatively correlated with Cd and Zn content in edible branches (P < 0.001). Stepwise multiple linear regression analysis revealed that the soil HA-M fraction was the key contributing factor for Zn accumulation and translocation in S. androgynus. Moreover, based on our findings, the absorption, uptake, and translocation of Cd and Zn were mainly determined by metal speciation and the pH in the soil. Moreover, the competitive antagonistic mechanisms between Zn and Cd absorption also affected their accumulation in S. androgynus. Thus, AHAF can be used as a soil amendment to sustainably improve acidic soils and effectively reduce Cd and Zn accumulation in edible branches of S. androgynus.

Abstract
Methyltransferase-like 8 (METTL8) encodes a mitochondria-localized METTL8-Iso1 and a nucleolus-distributed METTL8-Iso4 isoform, which differ only in their N-terminal extension (N-extension), by mRNA alternative splicing. METTL8-Iso1 generates 3-methylcytidine at position 32 (m3C32) of mitochondrial tRNAThr and tRNASer(UCN). Whether METTL8-Iso4 is an active m3C32 methyltransferase and the role of the N-extension in mitochondrial tRNA m3C32 formation remain unclear. Here, we revealed that METTL8-Iso4 was inactive in m3C32 generation due to the lack of N-extension, which contains several absolutely conserved modification-critical residues; the counterparts were likewise essential in cytoplasmic m3C32 biogenesis by methyltransferase-like 2A (METTL2A) or budding yeasts tRNA N3-methylcytidine methyltransferase (Trm140), in vitro and in vivo. Cross-compartment/species tRNA modification assays unexpectedly found that METTL8-Iso1 efficiently introduced m3C32 to several cytoplasmic or even bacterial tRNAs in vitro. m3C32 did not influence tRNAThrN6-threonylcarbamoyladenosine (t6A) modification or aminoacylation. In addition to its interaction with mitochondrial seryl-tRNA synthetase (SARS2), we further discovered an interaction between mitochondrial threonyl-tRNA synthetase (TARS2) and METTL8-Iso1. METTL8-Iso1 substantially stimulated the aminoacylation activities of SARS2 and TARS2 in vitro, suggesting a functional connection between mitochondrial tRNA modification and charging. Altogether, our results deepen the mechanistic insights into mitochondrial m3C32 biogenesis and provide a valuable route to prepare cytoplasmic/bacterial tRNAs with only a m3C32 moiety, aiding in future efforts to investigate its effects on tRNA structure and function.

Abstract
The coconut (Cocos nucifera L.) is a commercial crop widely distributed among coastal tropical regions. It provides millions of farmers with food, fuel, cosmetics, folk medicine, and building materials. Among these, oil and palm sugar are representative extracts. However, this unique living species of Cocos has only been preliminarily studied at molecular levels. Benefiting from the genomic sequence data published in 2017 and 2021, we investigated the transfer RNA (tRNA) modifications and modifying enzymes of the coconut in this survey. An extraction method for the tRNA pool from coconut flesh was built. In total, 33 species of modified nucleosides and 66 homologous genes of modifying enzymes were confirmed using a nucleoside analysis using high-performance liquid chromatography combined with high-resolution mass spectrometry (HPLC-HRMS) and homologous protein sequence alignment. The positions of tRNA modifications, including pseudouridines, were preliminarily mapped using a oligonucleotide analysis, and the features of their modifying enzymes were summarized. Interestingly, we found that the gene encoding the modifying enzyme of 2'-O-ribosyladenosine at the 64th position of tRNA (Ar(p)64) was uniquely overexpressed under high-salinity stress. In contrast, most other tRNA-modifying enzymes were downregulated with mining transcriptomic sequencing data. According to previous physiological studies of Ar(p)64, the coconut appears to enhance the quality control of the translation process when subjected to high-salinity stress. We hope this survey can help advance research on tRNA modification and scientific studies of the coconut, as well as thinking of the safety and nutritional value of naturally modified nucleosides.

Abstract
The presence of pesticide residues in cowpea raises serious health concerns. In this study, a novel, sensitive, high-performance method was developed to simultaneously analyze the residues of 35 pesticides in cowpea samples from growing areas in the Hainan province of China, from November 2018 to June 2021. The method employs modified QuEChERS sample pretreatment coupled with gas chromatography-tandem mass spectrometry. The limits of quantification of the 35 pesticides in the cowpea matrix ranged from 1.0 to 8.0 μg/kg. Twenty-seven of the 35 pesticides were detected, twelve of which are banned for use on legumes in China. Residues for ten pesticides in 17.1% of the samples exceeded their MRLs, with the highest exceedance of 380% observed in difenoconazole. Moreover, 80.8% of the samples contained one or more pesticide residues, with the most frequently detected pesticide being chlorfenapyr with a detection rate of 46.3%. In addition, the pesticide triazophos was detected through different years and regions. Notably, the chronic dietary exposure risk (%ADI) of the detected pesticides, evaluated from the national estimated acceptable daily intake, was lower than 100% in Chinese people of different age groups.

Abstract
Post-transcriptional modifications affect tRNA biology and are closely associated with human diseases. However, progress on the functional analysis of tRNA modifications in metazoans has been slow because of the difficulty in identifying modifying enzymes. For example, the biogenesis and function of the prevalent N2-methylguanosine (m2G) at the sixth position of tRNAs in eukaryotes has long remained enigmatic. Herein, using a reverse genetics approach coupled with RNA-mass spectrometry, we identified that THUMP domain-containing protein 3 (THUMPD3) is responsible for tRNA: m2G6 formation in human cells. However, THUMPD3 alone could not modify tRNAs. Instead, multifunctional methyltransferase subunit TRM112-like protein (TRMT112) interacts with THUMPD3 to activate its methyltransferase activity. In the in vitro enzymatic assay system, THUMPD3-TRMT112 could methylate all the 26 tested G6-containing human cytoplasmic tRNAs by recognizing the characteristic 3'-CCA of mature tRNAs. We also showed that m2G7 of tRNATrp was introduced by THUMPD3-TRMT112. Furthermore, THUMPD3 is widely expressed in mouse tissues, with an extremely high level in the testis. THUMPD3-knockout cells exhibited impaired global protein synthesis and reduced growth. Our data highlight the significance of the tRNA: m2G6/7 modification and pave a way for further studies of the role of m2G in sperm tRNA derived fragments.

Abstract
Fluopyram is commonly used to control banana leaf spot, anthracnose, and scab in tropical agricultural areas. To explore its behaviour in tropical agricultural environments, dissipation, adsorption, and leaching behaviours of fluopyram in three typical banana planting soils were studied. Also, its dissipation and migration capabilities in different regions and different soil types were evaluated. The results showed that the dissipation of fluopyram was in accordance with the first-order kinetic equation in the three banana soils, but the degradation rates were quite different. The degradation half-lives in the Hainan latosol, Yunnan sandy soil, and Fujian Plain alluvial soil were 46.21 days, 36.48 days and 57.76 days, respectively. Fluopyram also exhibited high adsorption and low leachability in the three soils. The Fujian Plain alluvial soil had the highest adsorption capacity for fluopyram, while fluopyram had the low leachability in the Yunnan sandy soil.

Abstract
OBJECTIVE Recently, the role of long noncoding RNAs (lncRNAs) in tumor progression has caught attention in numerous researchers. In our investigation, lncRNA PCAT-1 was studied to identify how it functioned in the progression of ovarian cancer. PATIENTS AND METHODS LncRNA PCAT-1 expression was detected by quantitative Real-time polymerase chain reaction (qRT-PCR) in both ovarian cancer cells and tissue samples. Furthermore, to identify the function of PCAT-1 in ovarian cancer, cell proliferation, transwell assay and Matrigel assay were conducted. In addition, by performing qRT-PCR and Western blot assay, the underlying mechanism was explored. RESULTS PCAT-1 expression was remarkably higher in ovarian cancer samples when compared with that in corresponding ones. Moreover, cell proliferation, migration and invasion were inhibited after PCAT-1 was knocked down in ovarian cancer cells. Moreover, the mRNA and protein expression of KLF6 (Krüppel-like factor 6) was upregulated after PCAT-1 was knocked down. Furthermore, the KLF6 expression level was negatively related to the PCAT-1 expression level in ovarian cancer samples. CONCLUSIONS We showed that PCAT-1 promotes the progression of ovarian cancer through enhancing cell metastasis and proliferation via suppressing KLF6, which might be a novel therapeutic strategy in ovarian cancer.

Abstract
Triple-negative breast cancer (TNBC) is the most aggressive breast cancer, and thus, has limited treatment options. Neuropilin1 (NRP1) is a multi-functional transmembrane protein that interacts with a number of signaling receptors and plays an important role in cancer progression. Previous studies demonstrated that the expression of NRP1 is activated and promotes the progression of breast cancer particularly in TNBC compared to other molecular subtypes; however, whether or not the level of NRP1 expression is related to the progression of TNBC warrants further study. In the current study, we determined the expression and function of NRP1 and evaluated the clinical significance of NRP1 in patients with TNBC. In addition, we determined whether or not an NRP1 antagonist potentiates the inhibitory effects of paclitaxel (PTX) in patients with TNBC. In our clinical study, NRP1 had higher expression in TNBC tissues than non-TNBC tissues at the same stage, and NRP1 was an independent prognostic factor. Specifically, the high expression of NRP1 was associated with shorter survival in TNBC patients. In addition, TNBC cells treated with NRP1 antagonist significantly potentiated the effect of PTX on cell proliferation, cell migration, and apoptosis. Our findings suggest that NRP1 expression can act as an independent prognostic factor for TNBC patients, and the combination of PTX and an NRP1 antagonist may be an effective treatment regimen for TNBC.

Abstract
Hormesis is a concentration-response phenomenon characterized by low-concentration stimulation and high-concentration inhibition, which typically has a nonmonotonic J-shaped concentration-response curve (J-CRC). The concentration addition (CA) model is the gold standard for studying mixture toxicity. However, the CA model had the predictive blind zone (PBZ) for mixture J-CRC. To solve the PBZ problem, we proposed a segmented concentration addition (SCA) method to predict mixture J-CRC, which was achieved through fitting the left and right segments of component J-CRC and performing CA prediction subsequently. We selected two model compounds including chlortetracycline hydrochloride (CTCC) and oxytetracycline hydrochloride (OTCC), both of which presented J-CRC to Aliivibrio fischeri (AVF). The seven binary mixtures (M1-M7) of CTCC and OTCC were designed according to their molar ratios of 12:1, 10:3, 8:5, 1:1, 5:8, 3:10, and 1:12 referring to the direct equipartition ray design. These seven mixtures all presented J-CRC to AVF. Based on the SCA method, we obtained mixture maximum stimulatory effect concentration (ECm) and maximum stimulatory effect (Em) predicted by SCA, both of which were not available for the CA model. The toxicity interactions of these mixtures were systematically evaluated by using a comprehensive approach, including the co-toxicity coefficient integrated with confidence interval method (CTCICI), CRC, and isobole analysis. The results showed that the interaction types were additive and antagonistic action, without synergistic action. In addition, we proposed the cross point (CP) hypothesis for toxic interactive mixtures presenting J-CRC, that there was generally a CP between mixture observed J-CRC and CA predicted J-CRC; the relative positions of observed and predicted CRCs on either side of the CP would exchange, but the toxic interaction type of mixtures remained unchanged. The CP hypothesis needs to be verified by more mixtures, especially those with synergism. In conclusion, the SCA method is expected to have important theoretical and practical significance for mixture hormesis.

Abstract
BACKGROUND Epirubicin is a potent chemotherapeutic agent for the treatment of breast cancer. However, it may lead to cardiotoxicity and cardiomyopathy, and no reliable biomarker was available for the early prediction of epirubicin-induced cardiomyopathy. METHODS Global gene expression changes of peripheral blood cells were studied using high-throughput RNA sequencing in three pair-matched breast cancer patients (patients who developed symptomatic cardiomyopathy paired with patients who did not) before and after the full session of epirubicin-based chemotherapy. Functional analysis was conducted using gene ontology and pathway enrichment analysis. RESULTS We identified 13 significantly differentially expressed genes between patients who developed symptomatic epirubicin-induced cardiomyopathy and their paired control who did not. Among them, the upregulated Bcl-associated X protein was related to "apoptosis," while the downregulated 5'-aminolevulinate synthase 2 (ALAS2) was related to both "glycine, serine, and threonine metabolism" and "porphyrin and chlorophyll metabolism" in pathway enrichment analysis. CONCLUSIONS ALAS2 and the metabolic pathways which were involved may play an important role in the development of epirubicin-induced cardiomyopathy. ALAS2 may be useful as an early biomarker for epirubicin-induced cardiotoxicity detection.

Abstract
Chirality is an important property of molecules. The study of biological activity and toxicity of chiral molecules has important theoretical and practical significance for toxicology, pharmacology, and environmental science. The toxicological significance of chiral ionic liquids (ILs) has not been well revealed. In the present study, the enantiomeric joint toxicities of four pairs of chiral ILs 1-alkyl-3-methylimidazolium lactate to Allivibrio fischeri were systematically investigated by using a comprehensive approach including the co-toxicity coefficient (CTC) integrated with confidence interval (CI) method (CTCICI), concentration-response curve (CRC), and isobole analysis. The direct equipartition ray (EquRay) design was used to design five binary mixtures of enantiomers according to molar ratios of 1:5, 2:4, 3:3, 4:2, and 5:1. The toxicities of chiral ILs and their mixtures were determined using the microplate toxicity analysis (MTA) method. Concentration addition (CA) and independent action (IA) were used as the additive reference models to construct the predicted CRC and isobole of mixtures. On the whole, there was an enantioselective toxicity difference between [BMIM]D-Lac and [BMIM]L-Lac, and [HMIM]D-Lac and [HMIM]L-Lac, while no enantioselective toxicity difference was observed for [EMIM]D-Lac and [EMIM]L-Lac, and [OMIM]D-Lac and [OMIM]L-Lac. Thereinto, the enantiomer mixtures of [BMIM]D-Lac and [BMIM]L-Lac, and [HMIM]D-Lac and [HMIM]L-Lac presented antagonistic action, and the enantiomer mixtures of [EMIM]D-Lac and [EMIM]L-Lac, and [OMIM]D-Lac and [OMIM]L-Lac overall presented additive action. Moreover, the greatest antagonistic toxicity interaction occurred at the equimolar ratio of enantiomers. Based on these results, we proposed two hypotheses, (1) chiral molecules with enantioselective toxicity difference tended to produce toxicity interactions, (2) the highest or lowest toxicity was usually at the equimolar ratio and its adjacent ratio for the enantiomer mixture. These hypotheses will need to be further validated by other enantiomer mixtures.

Abstract
BACKGROUND Microscopic structures of the ossification centres of the odontoid process were studied from the micro-computed tomography (CT) images of the axis, and the potential influence of the ossification centres with different microscopic structures on odontoid process fractures was analysed. MATERIALS AND METHODS Eighteen odontoid process specimens were randomly collected and scanned by micro-CT. The obtained images were then input into the software for further observation and measurement. Incomplete absorption of the ossification centres in the base was observed, along with the anatomic structure of the regions with incomplete ossification and structural parameters of the trabecular bones. RESULTS The microscopic structures of the trabecular bones in the ossification centres in the base of the odontoid process could be clearly visualised from the micro-CT images. Among the 18 odontoid process specimens, 11 specimens were found with incomplete absorption of the ossification centres in the axis, the prevalence reaching up to 61%. Regions with incomplete ossification varied in size and morphology, and their three-dimensional morphology was predominantly oval. Of all structural parameters examined for the trabecular bones, there were only significant differences in the degree of anisotropy between the regions with incomplete absorption of ossification centres and the average vertebral trabecular bones (p < 0.05). CONCLUSIONS Incomplete absorption of the ossification centres in the base of the odontoid process is a relatively prevalent condition. The cavitation effect of the trabecular bones may be the primary cause for odontoid process fractures.

Abstract
A fluorometric assay is described for the determination of Cd(II) in environmental and agricultural samples. It is making use of a molecularly imprinted polymer (MIP) and aptamer as dual recognition units, while carbon quantum dots (co-doped with sulphur and nitrogen) and gold nanoparticles (SN-CQD/Au) act as the fluorophores. The aptamer-modified MIP was placed on an SN-CQD/Au-modified indium tin oxide glass electrode. Cd(II) was detected with high selectivity by the recognition sites of the aptamer in the MIP. Fluorescence, with excitation/emission peaks at 370/430 nm, is quenched by Cd(II). Response is linear in the 20 pM to 12 nM concentration range. The detection limit is 1.2 pM. The sensor is selective for Cd(II), and recoveries from spiked waters, soils and vegetables real-world samples range between 82.1 and 113.9%. Graphical abstractA fluorescence sensor composed of a molecularly imprinted polymer and an aptamer as a dual identification system for Cd2+ coupled with and carbon quantum dots (co-doped with sulphur and nitrogen) and gold nanoparticles (SN-CQDs/Au) as fluorescent element that can detect Cd2+ with high selectivity by a dual-recognition mechanism.

Abstract
Objective:To evaluate the influence of voice disorders on children's quality of life through the parental version of pediatric voice-related quality of life(pVRQOL). Method:Three hundred and eighty-six children from August 2017 to December 2018 were enrolled in this study. A total of 214 parents of children had voice disorders(dysphonic group), and 172 parents of children were without voice disorders(control group). Both groups were filled out the questionnaire containing the parental version of pVRQOL. Result:① The most common disease in children with voice disorder was vocal fold nodule, and boys were more susceptible to voice disorder than girls(71.5%, 28.5%); ②In dysphonic group, the scores of total(91.40±8.63, 97.94±4.23), physiology and function(87.55±10.98, 96.99±6.10), social emotion(98.86 ±3.29, 99.73±1.08) were lower than those in control group(P<0.01); ③In dysphonic group, there was a correlation between the parents' overall evaluation of the children's voice quality and the three dimensions of the parental version of pVRQOL(total: r=-0.398, P<0.01, physical function: r=-0.448, P<0.01, social-emotion: r=-0.125, P<0.05). Conclusion:Voice disorders could cause a negative impact on children's voice related quality of life. pVRQOL could be applied to assess the voice-related quality of life in children with voice disorders.

Abstract
Objective:The aim of this study is to investigate the voice function change in patients who underwent total thyroidectomy between preoperative and the third day postoperative, Taking the result data to explore methods for voice protection and be valuable for clinical diagnose and treatment. Method:Three hundred and fifth-three patients with thyroid papillary carcinoma without preoperative vocal dysfunction were treated with total thyroidectomy and single or bilateral central cervical lymph node dissection. At preoperative and the third day postoperative, videostroboscopic, acoustic analysis, voice handicap index 10(VHI-10)are measured. Result: At the third day postoperative, 294 (83.29%)patients have voice symptoms,the most common voice disorder is hoarseness in 105 cases (35.71%),phonasthenia in 78 cases(26.53%),unable speak louderly in 53 cases (18.03%), unable speak high-pitch in 24 cases (8.16%), unable speak low-pitch in 29 cases (9.86%), pronunciation leakage in 5 cases (1.70%). Videostroboscopic examinations are normal in all patients at the third day postoperative. The total score of VHI-10, Physiology(P), Emotion(E) dimensions in VHI-10 between preoperative and the third day postoperative are statistically significant (P<0.05). For male patients, the acoustic analysis (fundamental frequency, Harmonicto Noise Ratio, Shimmer and Maximum phonation time) are statistically significant between preoperative and the third day postoperative (P<0.05). For female patients, acoustic analysis (fundamental frequency, Harmonicto Noise Ratio, Shimmer, Jitter and Maximum phonation time) are statistically significant between preoperative and the third day postoperative (P<0.05). Conclusion:These patients who underwent total thyroidectomy with bilateral or unilateral central partment lymph node dissection may develop voice complications even their recurrent laryngealnerve be undamaged during the surgery. Changes in surgery and voice may cause changes in the patient's psychology, suggesting that clinicians need to have adequate communication between doctors and patients before surgery, pay attention to the patient's voice quality and psychological changes, and give positive intervention.

Abstract
Objective:To discuss the clinical diagnosis, therapies and prognosis of adenoid cystic carcinoma of external auditory canal.Method:Eleven patients with adenoid cystic carcinoma of external auditory canal, who had been admitted to West China hospital, Sichuan university from April 2009 to October 2015 were recruited and a retrospective analysis was performed.Result:All the 11 patients were treated with surgery except one elderly with T1 stage who was only treated with radiotherapy(RT),1 of the 10 patients treated with surgery were added on radiotherapy after surgery. Following up for 12-104 months,the patient who was treated with RT alone has survived with carcinoma for 51 months by now,among the remainder stage T1 patients,one was reoperated for local recurrence 95 months after surgery, and therefore survived without recurrence.The other 2 patients all survived with free-disease;in the stage T2 patients,one was lost to follow-up after identified local recurrence with pulmonary masses 12 months after surgery, another one committed suicide because of family problems 56 months after operation,and the other one survived without recurrence for 57 months after surgery; the stage T3 patient survived without recurrence for 26 months at present;in the T4 patients, one died after gamma knife therapy for local recurrent disease with brain metastasis 22 months after surgery, another one died from pulmonary metastasis 17 months after surgery,and the other one survived without recurrence for 56 months.Conclusion:Adenoid cystic carcinoma of external auditory canal is a rare disease with high misdiagnosis rate and progresses slowly.Surgery is the preferred therapy.The prognosis is closely related to disease clinical stage at presentation type of pathology and surgical approaches. Adenoid cystic carcinoma of external auditory canal is characteristically susceptible to local recurrence and distant metastasis,inaddition to routine re-exam of ear,the patients should be reviewed carefully to exclude of pulmonary,brain and kidney metastasis during follow-up.

Non-Hodgkin' s lymphoma is a kind of disease which might manifest in varied form. Unlike squamous cell carcinoma, the majority of laryngeal tumors, non-Hodgkin' s lymphoma in larynx is extremely rare. Here we present a primary laryngeal non-Hodgkin' s lymphoma, a 66-year-old female, with a history of recurrent sore throat and hoarseness for over 1 year. Laryngoscope and computed tomography result were presented, and surgical resection was performed under the suspension laryngoscope using CO₂ laser. According to the pathological immunohistochemistry result, the final diagnosis was laryngeal non-Hodgkin' s lymphoma. Postoperative adjuvant chemotherapy was applied. There was no recurrence.

Abstract
To supply actual data for assessing the potential threat from difenoconazole to the ecosystem, its practical environmental behaviors in a mango field were investigated through a novel mode. After optimization, a UPLC-MS/MS determination method with good accuracy and stability was developed that could be used for the residue determination. Difenoconazole residue was in situ sampled, and its degradation and transportation activity, which reflected the actual transfer characteristics in the natural environment, were researched. The results showed that the half-life of difenoconazole in the soil was 15.4 days, which may be accumulated in a year-round agricultural production system. The residue was detected in the rain settled underground, which showed that the residue transported gradually with the rainfall in vertical and horizontal directions. The results showed that difenoconazole would transport with the rainfall, although the process was slow. All the data showed that the soil ecosystem, and probably also the aquatic ecosystem, would be affected by difenoconazole residue. Actual data for assessing the potential threat from the environmental behaviors of the difenoconazole to the ecosystem in mango field could be provided by the novel experimental design.![]()

Abstract
Objective:To investigatethe effect of voice therapy on anxious and depressive in patients with voice disorders.Method:The patients who received voicee therapy in our department from May 2014 to July 2016 were enrolled in our study and evaluated by self-rating anxiety scale (SAS) and self rating depression scale (SDS), before and after voice therapy.result:Before voicee therapy, the score of SAS and SDS were 47.52±11.15 and 48.63±8.70 respectively, which were higher than domestic norm (37.23±12.59 and 41.88±10.57 for SAS and SDS, respecative) with P< 0.05. After voice therapy, the score of SAS and SDS were 38.03±6.95 and 42.21±7.71, which were lower than the score of before voice therapy (P< 0.05). And compared with the domestic norm, the difference was not statistically significant (P> 0.05).Conclusion:The anxiety and depression scores of patients with voice disorders are higher than those of ordinary people. The voice therapy can effectively relieve anxiety and depression of patients with voice disease.
