Abstract
Objective: To investigate risk factors for hyperkalemia among chronic kidney disease (CKD) patients and establish a risk assessment model for predicting hyperkalemia events. Methods: Clinical data of CKD patients (stage 3 to 5) hospitalized between May 2017 and June 2020 from 14 hospitals were retrospectively collected and divided into training dataset and validation dataset through balanced random sampling. Multivariate logistic regression analysis was used to analyze risk factors for hyperkalemia in CKD patients and the factors were scored. Receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated. Meanwhile, the cut-off value with the best sensitivity and specificity were used to verify the accuracy of the model in validation dataset. Results: A total of 847 CKD patients were enrolled and further divided into training dataset (n=675) and validation dataset (n=172). There were 555 males and 292 females, with a mean age of (57.2±15.6) years. Multivariate logistic regression analysis showed that age, CKD stage, history of heart failure, history of serum potassium ≥5.0 mmol/L, diabetes, metabolic acidosis, and use of medications that increase serum potassium levels were risk factors for causing hyperkalemia in patients with CKD. Risk assessment model was established based on these risk factors. The AUC of the ROC curve was 0.809. Using 4 as the cut-off value, the sensitivity and specificity for predicting hyperkalemia events reached 87.1% and 57.0%, respectively. Conclusion: The model established in the current study can be used for predicting hyperkalemia events in clinical practices, which offers a new way to optimize serum potassium management in patients with CKD.

Abstract
TanSat is the 1st Chinese carbon dioxide (CO2) measurement satellite, launched in 2016. In this study, the University of Leicester Full Physics (UoL-FP) algorithm is implemented for TanSat nadir mode XCO2 retrievals. We develop a spectrum correction method to reduce the retrieval errors by the online fitting of an 8th order Fourier series. The spectrum-correction model and its a priori parameters are developed by analyzing the solar calibration measurement. This correction provides a significant improvement to the O2 A band retrieval. Accordingly, we extend the previous TanSat single CO2 weak band retrieval to a combined O2 A and CO2 weak band retrieval. A Genetic Algorithm (GA) has been applied to determine the threshold values of post-screening filters. In total, 18.3% of the retrieved data is identified as high quality compared to the original measurements. The same quality control parameters have been used in a footprint independent multiple linear regression bias correction due to the strong correlation with the XCO2 retrieval error. Twenty sites of the Total Column Carbon Observing Network (TCCON) have been selected to validate our new approach for the TanSat XCO2 retrieval. We show that our new approach produces a significant improvement on the XCO2 retrieval accuracy and precision when compared to TCCON with an average bias and RMSE of -0.08 ppm and 1.47 ppm, respectively. The methods used in this study can help to improve the XCO2 retrieval from TanSat and subsequently the Level-2 data production, and hence will be applied in the TanSat operational XCO2 processing.

Abstract
Macrophages have been reported to participate in inflammation, tissue homeostasis and tissue repair. The detailed mechanism of macrophage-mediated tissue repair is not clear. CXCL-10, secreted by monocytes, endothelial cells and fibroblasts, mediates immune response and angiogenesis by binding to CXCR3. In this study, the expression of CXCL-10 and CXCR3 in porcine lung injury induced by porcine reproductive and respiratory syndrome virus (PRRSV) infection was firstly examined. The results showed that the expression of both CXCL-10 and CXCR3 increased in the infected pig lungs. In addition, the increased expression of CXCL-10 and CXCR3 in macrophage treated by poly (I:C) was also observed, suggesting the autocrine system existed in macrophages. Furthermore, CXCL-10 treatment induced upregulation of Arg1 and VEGFa, and downregulation of TNFα in macrophage, and CXCR3 antagonist AMG487 treatment presented the contrary effects on the expression of Arg1, VEGFa, and TNFα. CXCL- 10-stimulated effects were dependent on PI3K/Akt signaling pathway. Wound-healing assay showed that CXCL-10 treatment macrophage conditioned medium promoted the healing process of endothelial cells. Our results suggested that CXCL-10/CXCR3 in macrophage may mediate tissue repair by regulating the macrophage expression of Arg1, VEGFa and TNFα. Modulation of CXCL-10/CXCR3 axis in macrophage may be a potential therapeutic strategy for tissue injury and repair.

Abstract
Introduction The prediction of the impact of olfactory impairment on cognitive decline in older adults has been different among different age groups. Objective This meta-analysis sought to estimate the predictive power of olfactory impairment on cognitive decline during follow-up in older adults of different ages. Material and methods A medical literature search was carried out using these databases for eligible studies: MEDLINE, COCHRANE and EMBASE. Studies recording olfaction and cognition detection at the beginning and end of the follow-up were included in the preliminary screening. The medical records of older adults without cognitive impairment at the beginning of the follow-up were taken into account in this analysis. Raw data was extracted in order to estimate the relative risk and the corresponding 95% confidence interval (95% CI). Subgroup analysis of age was performed to eliminate the effect of age on the results. Statistical heterogeneity was measured using the I2 index and Cochran's Q test. Results Eight studies were enrolled in this analysis (3237 events and 13165 participants), and the pooled relative risk for the 70–80 years old subgroup was 2.00 (95% CI = 1.79–2.23). Conclusion Relatively, there is a higher risk of cognitive impairment at the end of follow-up in younger adults with olfactory impairment at the beginning of follow-up. The length of follow-up has a little effect on the relative risk.

Abstract
OBJECTIVE The cross-sectional area (CSA) and the volume of the pharyngeal airway normative reference data aren't established, although they are closely associated with the pathogenesis of obstructive sleep apnea syndrome (OSAS) in infants and preschool children. Our objective is to measure the cross-sectional area (CSA) and volume of pharyngeal airway subregions and investigate the effects of age and sex in infants and preschool children using computerized tomography (CT). METHODS After applying strict inclusion criteria, 57 infants and preschool children (27 females, 30 males) aged from 1 day to 72 months who underwent maxillofacial CT scans due to trauma were selected. The sample was stratified into three age groups (1 day-24 months, 25-48 months, and 49-72 months). The CSA and the volume of the naso-, palato-, glosso-, and laryngopharyngeal airway were calculated using a 3-dimensional image processing software. Linear regression analysis was performed to express the effect of age, height, and weight. One-way analysis of covariance with height as a covariate was used to analyze the statistical significance of the difference between males and females within each age group. RESULTS The CSA and volume of all pharyngeal airway subregions increased with age, height, and weight (P < 0.05) in children under 6 years old. Multiple linear regression analysis showed an age effect, identified in all measurements (P < 0.001), whereas no height or weight effect were found. There were no differences in any measurements between males and females within each age group. CONCLUSION The normative reference data of CSA and volume of pharyngeal airway subregions were established after applying strict inclusion and exclusion criteria in infants and preschool children. Results may be useful in screening and assist in the timely diagnosis and management of pediatric OSAS.

Abstract
OBJECTIVES This study explored the factors influencing health behaviours during the coronavirus disease 2019 (COVID-19) outbreak in China. The impact of perceived stress and positive perception of interventions on health behaviours in China were assessed using the extended information-motivation-behaviour skills (IMB) model. STUDY DESIGN Cross-sectional survey. METHODS The Questionstar online survey tool was used to construct a structured questionnaire based on the IMB model. Between 14 and 22 February 2020, during the peak of COVID-19 epidemic in China, 2449 participants were recruited by snowball sampling on WeChat and Tencent QQ social media platforms in China. Data were collected through an online questionnaire, and structural equation modelling was performed to evaluate the extended IMB model. RESULTS Health behaviours were assessed using a scoring system (total score range: 8-40); the average health behaviour score in this study was 34.62 ± 4.44. The term 'health risk stress' refers to the impact that perceived stress has on health, and this was experienced by 39.9% of participants. Only 35.9% of participants answered all seven questions on COVID-19 information correctly. The final model showed that information, motivation, behavioural skills, heath risk stress and positive perception of interventions had significant direct effects on health behaviours. Health behaviours were positively associated with the positive perception of interventions but negatively associated with health risk stress. Behavioural skills had the greatest impact on health behaviours. CONCLUSIONS In the face of public health emergencies, the extended IMB model has been used as a theoretical framework to construct more effective interventions. The government should pay attention to publicity and guidance, strengthen positive interactions with the public and disclose relevant information in a timely manner to gain trust and to maintain the positive public perception of the interventions. In terms of health education, the government should focus on behavioural skills, promptly rectify ineffective prevention information and raise awareness about the disease to relieve stress and anxiety in the population.

Abstract
BACKGROUND: Multidrug- and extensively drug-resistant tuberculosis (MDR/XDR-TB) continues to be a challenge in China. Bedaquiline (BDQ) is associated with accelerated sputum culture conversion and favourable treatment outcomes when added to a preferred background regimen. This post-hoc study aimed to assess the outcomes of BDQ treatment in Chinese patients with MDR/XDR-TB.METHODS: Data from 51 Chinese patients who participated in a global Phase 2, open-label, single-arm study (TMC207-C209) were analysed for effectiveness and safety of the BDQ-containing regimen.RESULTS: During the 24-week BDQ treatment, adverse events (AEs) occurred in 48 patients (94.1%), with the most common AE being hyperuricemia. Drug-induced liver injury (DILI) was reported in 13 patients (25.5%); serious DILI was reported in one patient (2.0%). Seven (13.7%) AEs were considered to be possibly related to BDQ by the investigators. Only one Grade 1 QTc prolongation was reported; no QTcF >500 ms was reported. One death occurred after BDQ treatment due to progressive TB. The median time to sputum culture conversion was 85 days based on the 24-week data. The sputum culture conversion rate was 82% at 24 weeks and 78% at 120 weeks; 66% of patients achieved a cure.CONCLUSIONS: BDQ was well-tolerated and effective for treating MDR-TB among Chinese patients.

Abstract
OBJECTIVES To explore the effect of gastroesophageal reflux disease (GERD) on Eustachian tube function in patients with obstructive sleep apnea (OSA). METHODS This was a cross-sectional study. The patients were divided into 4 groups according to OSA and GERD: OSA+GERD group; OSA-only group; GERD-only group; and normal control group. RESULTS There were no differences among the 4 groups regarding age, sex, smoking history, and alcohol history (all P > .05). The patients in the OSA and OSA+GERD groups had a significantly larger body mass index than those in the control and GERD-only groups (all P < .05). The proportions of patients with abnormal ETS-7 and ETD-Q results were higher in the GERD and OSA+GERD groups compared to the control group (P < .008). There were no significant differences in ETS-7 and ETD-Q between the control and the OSA-only groups (P > .008). The multivariable analysis showed that only GERD was independently associated with abnormal ETS-7 results (odds ratio = 3.090, 95% CI: 1.332-7.169, P = .009). CONCLUSION Given the high concomitance rate in patients with OSA, GERD might be an important association factor of Eustachian tube dysfunction in patients with OSA.

Abstract
It is demonstrated that Mg, Cr, Mn and B can be doped close to GaAs surface by plasma doping without external bias at room temperature (RT). The process only takes a few minutes, and impurity densities in the range of 1018-1021/cm₃ can be achieved with doping depths about twenty nanometers. The experiment results are analyzed and the physical mechanism is tentatively explained as follows: during the doping process, impurity ion implantation under plasma sheath voltage takes place, simultaneously, plasma stimulates RT diffusion of impurity atom, which plays the main role in the doping process. The enhanced RT diffusion coefficients of Mg, Cr, Mn and B in GaAs are all in the order of magnitude of 10-15 cm₂sec-1. This is reported for the first time among all kinds of plasma assisted doping methods.

Abstract
OBJECTIVE/HYPOTHESIS To investigate the impact of obstructive sleep apnea syndrome (OSAS) on the olfactory and gustatory functions, and the potential mechanisms affecting olfactory and gustatory functions. MATERIALS AND METHODS A total of 120 men between the ages of 41 and 70 (mean age (SD) = 56 ± 7.5) were divided into three groups according to polysomnography results: snoring group, mild to moderate OSAS group, and severe OSAS group. Olfactory and gustatory functions were evaluated by the Sniffin' Sticks test and the triple-drop method, respectively. Otorhinolaryngologic examination, as well as sleep and quality of life questionnaires, were completed by all subjects one day before or after polysomnography. RESULTS There was a significant difference in odor thresholds (THR), odor discrimination (OD), odor identification (OI), thresholds-discrimination-identification (TDI) (p < 0.001, p < 0.001, p = 0.003, p < 0.001), and total taste score (p = 0.004, p = 0.021, p = 0.006) in all three groups. Of the subjects in the OSAS group, 43 (54%) exhibited olfactory dysfunction, including 18 subjects (45%) in the mild to moderate group and 25 subjects (63%) in the severe group. Significant negative correlations were found between all olfactory parameters and polysomnography parameters. Furthermore, a negative correlation was present between the total taste scores and the apnea-hypopnea index (AHI). CONCLUSION Men with OSAS exhibited impairment in olfactory and gustatory functions. Significant correlations were found between AHI and olfactory parameters, as well as between AHI and total taste scores.

Abstract
PURPOSE Accurate identification of low-grade gliomas (LGGs; World Health Organization grades I and II) and their differentiation from brain inflammation lesions (BILs) remains difficult; however, it is essential for treatment. This study assessed whether a one-day protocol for voxel-wise 18F-FDG and 13N-ammonia PET/CT with uptake decoupling analysis could differentiate LGGs from BILs. MATERIALS AND METHODS Twenty-eight patients with LGGs and 16 patients with BILs underwent 18F-FDG and 13N-ammonia PET/CT on the same day before any type of therapy. The decoupling score and tumor-to-normal tissue (T/N) ratio of 18F-FDG and 13N-ammonia were calculated at each location. Student's t-test was used to compare values, and ROC curve analysis was used to establish a cut-off value for the T/N ratio and decoupling score. Area under the curve (AUC) was calculated to evaluate differential efficacy. RESULTS Significant differences were observed in 13N-ammonia T/N ratio (p=0.018) and decoupling score (p=0.003) between LGGs and BILs; however, the 18F-FDG T/N ratio did not show any differences (p=0.413). Optimal cut-off values for 18F-FDG T/N ratio, 13N-ammonia T/N ratio, and decoupling score were 0.73, 0.97, and 2.31, respectively, with corresponding AUCs of 0.48, 0.68, and 0.77. The respective sensitivity, specificity, and accuracy parameters using these cut-off values were 53.6%, 62.5%, and 56.8%, respectively, for 18F-FDG; 50.0%, 75.0%, and 59.1%, respectively, for 13N-ammonia; and 60.7%, 93.8%, and 72.7%, respectively, for decoupling score. CONCLUSIONS 18F-FDG/13N-ammonia uptake decoupling score can be used to discriminate between LGGs and BILs. Use of a decoupling map of these two tracers can improve visual analysis and diagnostic accuracy.

Abstract
OBJECTIVE Currently, pathogenesis of non-small cell lung carcinoma (NSCLC) is still unknown and the treatment is far from ideal. Therefore, we investigated the effect of inhibiting microRNA-520a-3p in NSCLC cells. MATERIALS AND METHODS NCI-H157 cells were treated with microRNA-520a-3p analogs for 48 h, or microRNA-520a-3p analogs and its inhibitor, for a total of 48 h. Many tests were performed, including MTT, flow cytometry, wound healing assay and transwell assay. The tumor model was established, and HMGB1 mRNA was detected by RT-PCR. Protein levels of HMGB1, MMP-2, MMP-9, Bcl-2, Bax, and Caspase-3 were assessed by Western Blot. RESULTS microRNA-520a-3p could significantly inhibit the proliferation, migration and invasion of NCI-H157 cells, inducing their apoptosis. microRNA-520a-3p inhibited tumor growth and decreased the mRNA and protein levels of HMGB1. Additionally, it decreased the Bcl-2/Bax ratio, MMP-2 and MMP-9 expression, and increased caspase-3 expression. CONCLUSIONS microRNA-520a-3p exhibited an effective inhibition on NCI-H157 tumor growth likely by inhibiting HMGB1 expression.

Abstract
Objective: To explore the incidence regularity and characteristics of pneumoconiosis among migrant workers in Shiyan city, and to provide a basis for making policies about pneumoconiosis prevention and treatment among migrant workers. Methods: In September 2018, 338 cases of pneumoconiosis among migrant workers and 354 cases of pneumoconiosis among non-migrant workers were collected between 2013 and 2017. The proportions of pneumoconiosis types, the age and seniority of onset workers, the severity grade of pneumoconiosis, the type of pneumoconiosis, the type of work and regional distribution, etc. were analyzed. Results: The age at onset of pneumoconiosisand the length of service of migrant workers and non-migrant workers in Shiyan city were significantly different (t=2.237, 3.208, P<0.05) . The proportion of pneumoconiosis stage was significantly different from that of non-migrant workers (χ(2)=47.897, P<0.05) , among migrant workers, the types of pneumoconiosis were mainly silicosis (308 cases, 91.1%) , coal worker's pneumoconiosis (29 cases, 8.6%) . The leading work types are rock drilling (115 cases, 34.0%) and blasting (105 cases, 31.1%) . The industry was mainly engaged in non-ferrous metal mining (205 cases, 60.7%) and coal (105 cases, 31.1%) . The area distribution involved each counties of Shiyan city, with Zhushan county (175 cases, 51.8%) and Yunxi county (125 cases, 37.0%) as the top two districts in number of cases. Of the cases of migrant workers, 89 cases (26.3%) had blood relationship with any others. There was no work-related injury insurance for migrant workers with pneumoconiosis. Conclusion: There is a high incidence of pneumoconiosis among migrant workers in Shiyan city, featured with the phenomenon of "late occurrence" and "family clustering", so it is urgent to strengthen the prevention and treatment of pneumoconiosis of migrant workers.

Abstract
OBJECTIVE To evaluate the diagnostic performance of MRI for the assessment of inferior vena cava (IVC) wall invasion by IVC thrombus in patients with renal cell carcinoma (RCC). METHODS We retrospectively collected patients who underwent radical nephrectomy and thrombectomy for RCC between 2010 and 2018 at Peking University First Hospital. All the patients underwent imaging on a 1.5 Tesla or 3.0 Tesla MRI scanner. Fifty-six patients met the inclusion criteria. Preoperative imaging was reviewed by two radiologists blinded to details of the patient's surgical procedure and histopathology. Two radiologists measured the maximum anterior-posterior diameter and coronal diameters of the IVC and renal vein, and the craniocaudal extent of tumor thrombus, and evaluated the MRI features of IVC thrombus, including occlusion of the IVC lumen, the margin of the tumor thrombus (smooth vs. irregular), contact of the IVC thrombus and IVC wall, and altered signal of the IVC wall. Univariable and multivariable associations of clinical and radiographic features with IVC wall invasion were evaluated by Logistic regression. RESULTS Of the 56 patients [male: 43, female: 13, mean age: (55.64±0.43) years], 17 (30.36%) were detected with IVC wall invasion, and most were clear cell carcinoma. Tumor thrombus with IVC wall invasion showed an increase in length of IVC thrombus [(7.91±3.59) cm vs. (5.94±3.57) cm, P=0.049], and more features of complete occlusion of the IVC lumen (P=0.002), irregular margin of the IVC thrombs (P=0.005), contact of the IVC thrombus and IVC wall (P=0.001), and altered signal of the low-intensity vessel wall (P<0.001), with a sensitivity of 94.12% and a specificity of 79.49%. CONCLUSION The present study indicates that MRI could be a means of evaluating RCC with IVC wall invasion, and the combination of tumor thrombus length and subjective impression of IVC wall invasion achieved a high sensitivity and specificity for diagnosis.

Abstract
OBJECTIVE To evaluate the clinicopathologic features and potential prognostic predictors of locally recurrent renal cell carcinoma patients after initial surgery. METHODS Authors retrospectively analyzed data extracted from 81 patients who were treated for postoperative locally recurrence of renal cell carcinoma from January 2006 to June 2016 in the Department of Urology, Peking University First Hospital. Postoperative locally recurrence of renal cell carcinoma was defined as disease recurring in the remnant kidney, renal fossa, adjacent abdomen, ipsilateral adrenal and retroperitoneal lymph nodes. RESULTS In the study, 81 patients were finally included, of whom 43 were initially treated in our hospital and 38 were initially treat in other centers. Partial nephrectomy (PN) was performed for 38 cases (26 in our hospital and 12 in other hospitals) as initial treatment and radical nephrectomy (RN) was conducted for the remnant 43 cases (17 in our hospital and 26 in other hospitals). Overall median recurrence time was 26 months (range: 3-164 months), in which 26 months (range: 3-55 months) for PN cases and 30 months (range: 4-164 months) for RN cases (P=0.009). Sixty-nine patients had single site recurrence, including remnant kidney (n=29), renal fossa (n=20), abdomen (n=4), ipsilateral lymph nodes (n=5), ipsilateral adrenal (n=11), while 12 patients had multiple sites recurrence. Seventy-eight patients were managed by complete surgical resection, while three patients were managed by radiofrequency ablation. Postoperative pathological diagnoses included clear cell carcinoma (n=72), papillary renal cell carcinoma (n=8, 7 cases with type 1, 1 case with type 2) and Xp11 translocation/TFE3 gene fusion renal cell carcinoma (n=1). Complete pathologic information of the initial surgery could be extracted from 43 patients who were initially treated in our hospital. Seventeen patients with initial radical nephrectomy were staged as T1a (n=4), T1b (n=2), T2a (n=1), T3a (n=8), and T3b (n=2). Twenty-six patients with initial partial nephrectomy were staged as T1a (n=18), T1b (n=7), and T3a (n=1). For PN cohort, the patients with T1a stage disease had longer median recurrence time than those with beyond T1a stage disease, and the difference was significant (29 months vs. 18 months, P=0.041). At the end of the follow-up, 58 patients were alive, 4 died and 19 lost the follow-up. Overall, 3-year and 5-year disease free survival rates were 81.9%, and 53.6%, respectively. CONCLUSION The present research reported a large-scale single central experience of locally recurrent renal cell carcinoma. The recurrence time of the PN group is shorter than that of the RN group. For patients after PN surgery, median recurrence time is longer for patients with T1a stage tumor when compared with those with stage beyond T1a. Patients can obtain relative long-term survival after complete secondary surgery resection.

Abstract
OBJECTIVE To compare the effects of thoracic epidural administration of lidocaine on hemodynamic and arousal responses of double lumen tracheal intubation during induction of anesthesia. METHODS In the study, 40 patients with American Society of Anesthesiologists (ASA) physical statuses I-II, aged 19-66 years, scheduled for elective thoracic surgeries under general anesthesia requiring orotracheal intubation were allocated to either the double-lumen endobronchial intubation (T group) or double-lumen endobronchial intubation after epidural administration of lidocaine (E group). After an intravenous anesthetic induction, the orotracheal double-lumen intubation was performed using a Macintosh direct laryngoscopy (MDLS), respectively. Invasive blood pressure (BP), heart rate (HR) and bispectral index (BIS) were recorded before and after anesthetic induction, immediately after intubation and 5 minutes after intubation with 1-minute interval and the intubation time also noted. The rate pressure product (RPP) was calculated. RESULTS After anesthetic induction, BP and RPP in the two groups decreased significantly compared with their preinduction values. In comparison with their postinduction values, the orotracheal intubation in the two groups caused significant increases in BPs, HRs and RPP. In comparison with their preinduction values, BPs decreased significantly in E group, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) increased significantly and lasted for 1 min in T group. The HRs of both groups after intubation were significantly higher than their baseline values , and increased in HR and lasted for 1 min and 4 min in E group and T group, respectively. SBP, DBP, MAP, HR and RPP after intubation in T group were significantly higher than those of E group during the observation period. The values of BIS were similar between both the groups. In T group, the incidences of SBP percent increased>30% of the baseline value and RPP more than 22 000 were significantly higher than in E group. None of the patients in group E had SBP more than 130% of the baseline value and RPP more than 22 000. CONCLUSION During double-lumen endobronchial intubation, epidural administration of lidocaine can provide less hemodynamic response and similar arousal response.

Abstract
Viral dsRNA acts as the paramount pathogen-associated molecular pattern on infection and orchestrates inflammation or immune cascades of the host's tissues. The comparative effects or mechanisms of inflammation or immunity in different organs on viral infections are critical in immunology or virology. To outline the organ-based molecular mechanisms of inflammation or immunity on viral infection, we challenged mice with the viral mimic poly(I:C) and quantified inflammatory cytokines Il-1b and TNF-α in the brain and lung tissues. As cytokines showed differential expression, transcriptome screenings of mouse lung and brain tissues were analyzed. We identified 629 differentially expressed genes (DEGs) in lung and 137 DEGs in brain tissues with a few overlapping genes. Most of those DEGs were interferon-stimulated genes (ISGs) that are involved in the anti-viral defense mechanisms. The expression patterns of viral dsRNA stimulated genes, and consequently, their association with different molecular mechanisms of inflammation and immunity were specific to the organs. The effects of viral mimic were higher in the lung than in the brain in terms of the number of DEGs and ISGs. Interestingly ribosomal protein L29 (Rpl29), a cell surface heparin-binding protein, was upregulated in the brain and downregulated in the lung. The contrasting expression of Rpl29 gene might be responsible for tissue-specific inflammatory responses in lung and brain tissue on virus infection. In addition, the upregulation of Tlr13, a dsRNA and bacterial 23s rRNA receptor, in the poly(I:C)-stimulated mouse lungs suggests its important role in lung inflammatory responses. It is likely that the combined effects of these genes orchestrate the organ-specific inflammatory or immune responses. Our findings would be beneficial to explore new insights in inflammation and immunity against many critical viral diseases.

Abstract
OBJECTIVES To investigate the expression changes of annexin A1 (ANXA1) during the process of skin incision healing, and to explore its expression and function during skin injury repair. METHODS The skin injury model of mice was prepared, and skin tissues of the controls and the injured group at 6 h, 12 h, 1 d, 3 d, 5 d, 7 d, 10 d and 14 d after injuries were taken. The morphological changes of the wound were observed by hematoxylin-eosin (HE) staining, and the expression of ANXA1 was detected by immunohistochemistry (IHC) and Western blotting. RESULTS HE staining showed normal healing of skin wounds. IHC results revealed that ANXA1 was expressed in the epidermis, hair follicle, sebaceous gland and vascular endothelium. In the injured group, the expression of ANXA1 was enhanced in epidermis and skin appendages around the wound 6-12 h after injury, and ANXA1 was also highly expressed in neutrophils and a small number of mononuclear cells. ANXA1 was mainly positively expressed in monocytes, neovascular endothelial cells and fibroblasts, and small amount of fibroblasts at 1-3 d, 5-10 d, and 14 d after injury, respectively. Western blotting showed that, compared with the controls, the expression of ANXA1 was significantly increased at 6 h after injury, peaked at 1 d, and then decreased gradually in the injured group. CONCLUSIONS ANXA1 may be involved in the regulation of skin damage repair, with time-dependent expression during skin wound healing, and thus is expected to be a biological marker for inferring the wound formation time.

Abstract
We have demonstrated that bovine blastocyst development was improved after culture in medium with only 6.25% of standard carbohydrate and amino acid concentrations, supplemented with fatty acids. However, these blastocysts had lower cell numbers. We hypothesised that this was due to deficiencies in embryo metabolism at the time of blastocyst formation. Thus, our objectives were to (1) determine whether using a sequential combination of nutrient concentrations could rescue blastocyst cell number; and (2) investigate the efficacy of reduced nutrient medium in 2 sources of oocytes. Oocytes were in vitro matured in identical medium either in our laboratory or during shipment from a commercial supplier. Oocytes in our laboratory were derived from feedlot heifers while purchased oocytes were obtained from culled cows. Zygotes were cultured using sequential medium with fraction V BSA. In step 1/step 2, embryos were cultured using 100% (glucose 0.5 mM/fructose 3.0mM, pyruvate 0.3/0.1mM, lactate 10.0/6.0mM, NEEA 1×/1× MEM, EAA 0.25×/0.5× MEM), 25% or 6.25% of standard nutrient concentrations. On Day 3, embryos were moved to step 2 as follows: 100% to 100%, 25% to 25%, 25% to 100%, 6.25% to 25%, or 6.25% to 100%. Lipid content of single mature oocytes from both sources was determined using gas chromatography coupled to an ISQ-LT MS/MS (GC-MS; Thermo Scientific, Waltham, MA, USA). Data (mean±s.e.m.) were analysed using ANOVA (P<0.05). When oocytes from feedlot heifers were used, blastocyst development and cell number did not differ between treatments. When oocytes from culled cows were used, blastocyst development was improved after embryo culture in 25-25% (45.1±3.3%) and 6.25-25% (46.6±3.2%) compared with 100-100% (34.2±3.2%). However, inner cell mass number of blastocysts cultured in 25-25% (25.6±2.5) and 6.25-25% (26.0±2.6) was reduced compared with 100-100% (41.4±4.5); TE and total cell number did not differ. Embryos cultured in 100-100%, 25-100%, and 6.25-100% were equivalent. Metabolomics revealed that 10 lipid compounds (polyunsaturated fatty acids, glycosyldiacylglycerols, and glycerophospholipids) differed in abundance between the two sources of oocytes. These results show that oocytes from different sources lead to different experimental outcomes, likely due to a combination of age, body condition, diet, and hormone treatment of the female. Oocytes from culled cows result in embryos that develop to blastocysts better in a reduced nutrient environment, although these embryos have fewer inner cell masses, suggesting that quality may be reduced. Embryos from feedlot heifer oocytes are relatively immune to nutrient fluctuations. Different endogenous fatty acid reserves in the oocyte may lead to differing metabolic strategies in the subsequent embryo, altering their response to substrate availability during in vitro culture. These results also demonstrate that reduction of nutrients during culture has no detrimental effect on blastocyst development or total cell number in either oocyte source, but that inner cell mass formation requires increased nutrient provision.

Abstract
Alterations in the signalling of critical molecular factors within the uterine milieu result in deficiencies in embryo elongation, leading directly to embryonic loss as well as delayed elongation. The objective of this study was to identify metabolites within the uterine environment from populations of uniform and diverse porcine conceptuses as they transition between spherical, ovoid, and tubular conceptuses during the initiation of embryo elongation. White crossbred gilts (n=38) were bred at standing oestrus (designated Day 0) and again 24h later and randomly assigned to collection group. At Day 9, 10, or 11 of gestation, reproductive tracts were collected immediately following harvest and flushed with 40mL of RPMI-1640 media. Conceptus morphologies were assessed from each pregnancy to assign to 1 of 5 treatment groups based on these morphologies: (1) uniform spherical (n=8); (2) diverse spherical and ovoid (n=8); (3) uniform ovoid (n=8); (4) diverse ovoid and tubular (n=8); and (5) uniform tubular (n=6). Subsequently uterine flushings from these pregnancies were submitted for non-targeted profiling by gas chromatography-mass spectrometry (GC-MS) and ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) techniques. Raw spectral data were processed using the XCMS package in R (R Foundation for Statistical Computing, Vienna, Austria) and features were clustered using RAMclustR. Unsupervised multivariate principal component analysis was performed in R using pcamethods package, and univariate ANOVA was performed in R with a Benjamini-Hochberg false discovery rate adjustment. Principal component analysis of the GC-MS and UPLC-MS data identified 153 and 104 metabolites, respectively. Of the identified metabolites, 51 and 71 metabolites from the GC-MS and UPLC-MS analysis, respectively, corresponded to known compounds. After false discovery rate adjustment of the GC-MS and UPLC-MS data, 38 and 59 metabolites from the GC-MS and UPLC-MS analysis, respectively, differed (P<0.05) in uterine flushings from pregnancies for the 5 conceptus stages. Some metabolites were greater (P<0.05) in abundance for uterine flushings containing earlier stage conceptuses (i.e. spherical) such as uric acid, tryptophan, 5-hydroxy-L-tryptophan, and L-tryosine. In contrast, some metabolites were greater (P<0.05) in abundance for uterine flushings containing later stage conceptuses (i.e. tubular) such as creatinine, serine, isovaleryl-I-carnitine, and lauric diethaolamide. These data illustrate several putative metabolites that change within the uterine milieu as porcine embryos transition between spherical, ovoid, and tubular conceptuses.

Abstract
Objective: To compare the characteristics of X-ray, CT and MRI of Brucella spondylitis and tuberculous spondylitis and its significance for differential diagnosis. Methods: A total of 10 cases of Brucella spondylitis and 20 cases of tuberculous spondylitis confirmed from the clinical, laboratory or pathological department were enrolled between January 2014 and August 2017 in the Fifth Affiliated Hospital of Sun Yat-sen University and the Third Affiliated Hospital of Southern Medical University. The CT, MRI findings were retrospectively analyzed to improve the differential diagnosis of these two diseases. Results: Of the 10 cases of Brucella spondylitis, 8 were located only in the lumbosacral vertebrae, 1 in the thoracic vertebrae only, 1 in the cervical and thoracic vertebrae, 8 with invasive bone destruction, and 8 with narrowed intervertebral space. In 9 cases of intervertebral disc destruction, 7 cases developed paravertebral abscesses, 3 cases had sclerotic edges, all cases had no vertebral body flattening, 5 cases invaded the accessory, 4 cases formed sequestrum, and 6 cases invaded the spinal canal. There were 3 cases showing invasion of surrounding muscles. In 20 cases of tuberculous spondylitis, 12 cases were located in the lumbosacral vertebrae, 6 cases in the thoracic vertebrae only, 1 involved the thoracic vertebrae and lumbosacral vertebrae, 1 involved the neck, chest, and lumbosacral vertebrae. Bone destruction of bone, 19 cases of intervertebral space narrowing, 20 cases of intervertebral disc destruction, 18 cases of paraspinal abscess formation, 10 cases of sclerotic edge formation, 6 cases of vertebral body flattened, 16 cases of invading attachment. There were 17 cases of sequestrum formation, 13 cases of invasion of the spinal canal, and 12 cases of violation of surrounding muscles. There were statistical differences between the two types of imaging signs such as the type of vertebral destruction and the presence or absence of sequestrum. Conclusion: The type of vertebral destruction and the presence or absence of imaging features such as sequestrumwill facilitate the differential diagnosis of Brucella spondylitis and tuberculous spondylitis.

Abstract
Objective: To evaluate the effectiveness and safety of intelligent pressure control flexible ureteroscope for management of renal stones ≤2 cm. Methods: The clinical data of 267 cases of renal calculi treated with flexible ureteroscope lithotripsy at Department of Urology, Ganzhou People's Hospital from June 2015 to December 2017 were analyzed retrospectively. There were 129 male and 138 female patients, with a mean age of 51.2 years (ranging from 19 to 76 years). Among them, 145 patients underwent intelligent pressure control flexible ureteroscope (intelligent control group) and 122 patients underwent flexible ureteroscope ordinary (ordinary group). The t test, χ2 test or Fisher exact test were used for statistical analysis. The success rate of stone seeking, the stone free rates, the incidence of complications, the average operation time, the average hospital stay after operation were compared between the two groups. Results: The average mean operative time of the patients with intelligent control group was (26.17 ± 8.64) minutes, significantly shorter than (47.23±18.35) minutes of the ordinary group (t=1.968, P=0.000). The stone free rate of the patients with intelligent control group was 97.2%, it was higher than 86.0% of ordinary group (χ2=0.069, P=0.004). The complication rate of the patients with intelligent control group was 2.7%, which was significantly shorter than 18.0% of the ordinary group (χ2=17.586, P=0.000). However, there was no significant difference between the two groups in the success rate of stone seeking and postoperative hospital stay (P>0.05). Conclusion: Intelligent controlled pressure ureteral flexible ureteroscope has the advantages of short operation time, high stone free rate and less complications in the treatment of renal calculi ≤2 cm compared with flexible ureteroscope ordinary.

Abstract
PURPOSE EpCAM is a common marker used in the detection of circulating tumor cells (CTC). Disseminated cancer cells display the characteristics of epithelial-to-mesenchymal transition events. The purpose of this study was to assess the potential of epithelial membrane protein 2 (EMP2) as a novel biomarker for CTC retrieval in breast cancer. METHODS MCF7 and MDA-MB-231 cells were stained with either anti-EpCAM or anti-EMP2 mAbs, respectively, followed by flow cytometric assay to measure their expression levels. PBMCs isolated from healthy donors were used for breast cancer cell spiking. CD45-depleted PBMCs from breast cancer patients' blood were used for CTC capturing. Immunomagnetic separation was used to enrich breast cancer cells. Cytospin centrifugation was performed to concentrate the captured cells, followed by immunofluorescence staining with anti-CD45 mAb, anti-pan cytokeratin mAb and DAPI. Fluorescent images were taken using a confocal microscope for CTC counts. RESULT MDA-MB-231 cells had 2.56 times higher EMP2 expression than MCF7 cells, and EMP2 had a significantly higher capture efficiency than EpCAM for MCF7 cells. Furthermore, anti-EMP2 was capable of capturing MCF7 cells that escaped in the flow-through of anti-EpCAM. Likewise, EMP2 had a significantly higher capture efficiency on MDA-MB-231 cells when compared to MCF7 cells. Most importantly, EMP2 biomarker was successfully used for CTC capture in patients with primary breast cancer. CONCLUSIONS EMP2 is superior to EpCAM for capturing both MCF7 and MDA-MB-231 cells. Additionally, EMP2 is a novel biomarker and capable of capturing breast cancer cells in patient blood samples.

Abstract
PURPOSE To determine the association between serum periostin and the presence of diabetic retinopathy (DR). METHODS Serum periostin was detected in 114 healthy subjects, 122 patients with type 2 diabetes mellitus (T2DM) and 159 patients with DR and compared among groups. Clinical data and other laboratory measurements such as glycated hemoglobin (HbA1c), lipid profiles, serum creatinine (Cr) and high-sensitivity CRP (hsCRP) were also collected and compared among groups. For subgroup analysis, patients with DR were divided into a non-proliferated diabetic retinopathy (NPDR) group and a proliferated diabetic retinopathy (PDR) group. Multivariate analysis was performed using logistic regression models. RESULTS The serum periostin level was significantly higher in patients with diabetic retinopathy compared with healthy subjects and patients with T2DM (both P < 0.001, respectively). Also, the periostin level was significantly higher in the PDR group compared to the NPDR group (P = 0.044). Multivariate logistic regression revealed that serum periostin was independently associated with the presence of DR in patients with T2DM (P < 0.001). The receiver operating characteristic (ROC) curves for DR development using serum periostin showed that the area under the receiver operating characteristic curves (AUC) was 0.838 (P < 0.001). CONCLUSIONS The current study demonstrated that serum periostin is significantly associated with the presence of DR in patients with T2DM and is an independent risk factor of DR.

Abstract
BACKGROUND Candida parapsilosis is a common agent of fungaemia, but few outbreaks of Candida parapsilosis infection have been reported in China. AIM To elaborate an outbreak of nosocomial Candida parapsilosis sensu stricto fungaemia in a neonatal intensive care unit (NICU) of a comprehensive hospital in China from July to October 2017. METHODS Epidemics and characteristics of fungaemia cases were investigated. Surveillance samples were collected. Vitek 2 Compact System, internal transcribed spacer sequencing, and random amplified polymorphic DNA (RAPD) typing were conducted to identify the isolates. Antifungal susceptibility test was performed for all bloodstream isolates. FINDINGS Sixteen neonates were diagnosed as Candida parapsilosis sensu stricto fungaemia during this period. Presenting symptoms included leucopenia, thrombocytopenia, and respiratory crackles. Fifteen cases were cured whereas one case who suffered from severe concomitant diseases died. The isolates were susceptible to fluconazole, amphotericin B, itraconazole, voriconazole, and 5-fluorocytosine. A total of 313 surveillance samples were collected, and Candida parapsilosis sensu stricto was identified from 16 environmental samples and one sample from an ultrasonographer's hand. The colonized locations included wiping cloths, faucets, sinks, operating table, puddles in the bathroom, a ventilator, and an ultrasonic probe. The RAPD patterns of all the Candida parapsilosis sensu stricto isolates from bloodstream and surveillance samples were identical. The outbreak was controlled after a series of infection control measures. CONCLUSION Contaminated environment was associated with this outbreak. Close attention to immunocompromised patients, thorough environmental disinfection and hand hygiene should be strengthened in NICU.

Abstract
AIM To investigate whether peer support would reduce diabetes distress and improve glycaemic control when added to usual diabetes education among adults with Type 2 diabetes in China. METHODS We conducted a cluster randomized trial involving 400 adults with Type 2 diabetes from eight communities in Nanjing. All participants received usual education for an average of 2 h each month from physicians, certified diabetes educators, dieticians, psychologists and podiatric nurses. Peer support was led by trained peer leaders and included diabetes knowledge- and skills-sharing at least once a month, as well as peer-to-peer communication. The primary outcome was diabetes distress measured using the Diabetes Distress Scale at 12 months. Secondary outcomes included fasting plasma glucose, 2-h postprandial glucose and HbA1c concentration. Outcome data were collected from all participants at baseline, 6 months and 12 months. RESULTS From 2012 to 2013, there were 200 participants in each study arm at baseline. Compared with the usual education arm, the peer support with usual education arm had greater reductions in regimen-related distress (1.4 ± 0.6 vs 1.2 ± 0.4; P=0.004) and total distress (1.3 ± 0.4 vs 1.2 ± 0.3; P=0.038) at 6 months. At 12 months, the scores for emotional burden (1.2 ± 0.3 vs 1.4 ± 0.6; P=0.002), physician-related distress (1.1 ± 0.3 vs 1.3 ± 0.4; P=0.001) and total scores (1.2 ± 0.3 vs 1.3 ± 0.4; P=0.002) were significantly lower in the peer support with usual education arm than in the usual education arm. Fasting plasma glucose levels were lower in the peer support with usual education arm than in the usual education arm at 6 months (7.5 ± 1.95 vs 8.0 ± 2.2; P=0.044) and 12 months (7.0 ± 2.3 vs 7.6 ± 1.5; P=0.008). CONCLUSIONS Beyond the benefits of usual education, peer support was effective in reducing diabetes distress for Type 2 diabetes mellitus. (Clinical Trials Registry no: NCT02119572).

Abstract
Background Idiopathic olfactory loss (IOL) accounts for a sizable fraction of olfactory dysfunction, but very little is known about its etiology and electrophysiological changes in the olfactory pathway. Methods We analyzed the physiology of IOL using chemosensory event‐related potentials (ERPs) (olfactory and trigeminal: oERP and tERP) and olfactory pathway magnetic resonance imaging (MRI) measured in adult patients with IOL and healthy controls. Subjective olfactory function was measured by Toyota and Takagi (T&T) olfactometry and Sniffin’ Sticks (SS). Results Olfactory function was worse in patients with IOL compared to controls (T&T, p < 0.001; SS, p < 0.001). oERPs could be evoked in 17 IOL patients. Signals in these patients showed lower amplitude in the N1 and P2 waves than controls (p < 0.05 for both), but there were no difference in latency between the 2 groups (p > 0.05). tERP were detected in all patients and controls; there were no differences in latency and nor amplitude between the 2 groups (p > 0.05). The olfactory bulb (OB) volume was significantly smaller in the IOL group than controls (p < 0.001), but there was no difference in the olfactory sulcus depth between groups (p > 0.05). Better olfactory function was associated with increasing magnitude of N1 amplitude in oERPs (p < 0.05) and increasing OB volume (p < 0.05). Conclusion IOL patients show neurophysiologic deficits and some anatomic differences compared to healthy controls.

Abstract
OBJECTIVE To explore the effect of parecoxib on cerebral infarction in rats and the regulatory mechanism on hypothalamus orexin neurons (orexin) and protein expression. MATERIALS AND METHODS 60 SD male rats were randomly divided into sham operation group, model group and treatment group (20 rats in each group). Cerebral infarction model was established by modified Longa method. Rats in the treatment group were given parecoxib (2.5 mg kg-1) in tail by intravenous injection, while both the sham operation group and the model group were given the equal volume of sterile PBS solution in the tail vein. Continuous intervention of 72h was carried out in the three groups. Immunofluorescence staining and Western blot were used to detect the expression of orexin neurons and orexin protein in the hypothalamus of rats, respectively. RESULTS Immunofluorescence staining showed that the number of orexin positive cells in the model group was significantly less than that in the sham-operated group (p < 0.01). After treatment intervention, the number of orexin positive cells in the hypothalamus was significantly increased compared to that in model group (p < 0.01). Western blot analysis showed that compared with sham operation group, the expression of orexin in the hypothalamus of model group was significantly decreased (p < 0.01), whereas the expression of orexin protein was significantly elevated after parecoxib intervention (p < 0.01). CONCLUSIONS Parecoxib plays a therapeutic effect on cerebral infarction by up-regulating the orexin neuron.

Abstract
Epitaxial films and heterostructures of perovskite oxides attract tremendous scientific interest because of the unique phenomena therein. Especially important is the epitaxial growth of films subjected to substrate-induced misfit strain. We show here that in contrast to conventional misfit-controlled epitaxy, chemical bonds determine the crystal stability and strain in epitaxial films of sodium niobate on different cubic substrates. Strain relaxation in sodium niobate is independent of misfit magnitude and proceeds through perovskite-specific tilting of oxygen octahedra in addition to common defect formation. The observed structural relaxation evidences a major role of a large internal strain that originates from chemical bonds in the perovskite cell. The effect of chemical bonds on film strain is anticipated to also control the epitaxy of other perovskite oxides and related compounds.

Abstract
Lipids are a potent source of cellular energy and are metabolized within mitochondria via fatty acid β-oxidation, a process that also requires carnitine. Embryos metabolize lipids during pre-implantation development, but relatively little is known about the effect of fatty acid supplementation for early bovine embryogenesis in culture. The objective of this study was to evaluate the effect of lipid supplementation (via albumin) and l-carnitine (C; 5 mM) during embryo culture in a novel medium with reduced concentrations of nutrients, compared with our standard culture medium (control). Following in vitro maturation and IVF, zygotes were cultured using a serum-free sequential media system (0-72 h step 1; 72-168 h step 2). Concentrations of salts, bicarbonate, and protein [2.5 mg mL−1 fatty acid-free (FAF) or fraction V (FrV) BSA] were the same in all treatments to maintain consistent osmolarity and pH. Nutrients (glucose/fructose, citrate, lactate, pyruvate, amino acids, vitamins, and EDTA) were diluted to 6.25% of control. In addition to the control medium (100%+FAF; n = 587), experimental treatments included 6.25%+FAF+C (essentially lipid free; n = 573) and 6.25%+FrV+C (lipid rich; n = 585). Following in vitro culture (7 reps), hatching blastocysts were stained to determine inner cell mass (ICM; SOX2+) and trophectoderm (TE; CDX2+) cell numbers. Lipid content of single expanded blastocysts was determined using gas chromatography coupled to an ISQ-LT MS/MS (GC-MS). Data (mean ± SEM) were analysed by ANOVA. Embryo cleavage did not differ between treatments. Blastocyst development (per cleaved embryo) was higher (P < 0.05) after culture in lipid rich (38.3 ± 1.5%) compared with control (29.6 ± 2.2%) and lipid free (28.1 ± 3.6%). Blastocyst hatching was reduced (P < 0.05) in lipid free (1.4 ± 0.7%) but not in lipid rich (5.2 ± 1.7) compared with control (9.8 ± 2.1). However, blastocysts developed in lipid rich and lipid free had reduced cell numbers compared with control: TE, 98.7 ± 5.9 and 98.8 ± 9.1 v. 160.3 ± 9.0; ICM, 19.2 ± 2.9 and 25.2 ± 6.1 v. 43.3 ± 4.0; and total cell number, 117.9 ± 7.3 and 124.0 ± 8.7 v. 203.6 ± 10.2, respectively. Analysis by GC-MS identified 40 annotated lipids (i.e. triacylglycerols and phosphatidyl cholines) that were significantly reduced in blastocysts cultured in lipid rich compared with control. In summary, blastocyst development was significantly improved after supplementation of fatty acids and l-carnitine to a medium with reduced nutrient concentrations. The mechanism underlying this phenomenon may be related to increased lipid metabolism in the low nutrient environment. Although more embryos developed in this novel medium, these blastocysts had reduced cell numbers even though blastocyst expansion and hatching were not affected. This reduced nutrient medium may provide an experimental model in which to independently study pathways controlling cell proliferation and blastocyst development. Future studies will investigate whether embryo cell number can be rescued while maintaining improved blastocyst development.

Abstract
Objective:To discuss the validity and reliability of dysphonia severity index in evaluating the effect of diagnosis and treatment of laryngeal reflux related voice diseases. Method:54 cases of voice disease patients accompanied by laryngopharyngeal reflux from January 2016 to June 2017 in department of otorhinolaryngology of our hospital were divided into two groups according to treatment type. 32 cases in the operation group received laser surgery and standard acid suppression therapy for 6 weeks, and 22 patients in the non-operation group received standard acid suppression therapy for 6 weeks. 24 h multichannel impedance pH (MCII-pH) monitoring was carried out. The indexes of reflux symptom, reflux finding score, subjective auditory perception and objective acoustic parameters of voice were measured before and after treatment, and the dysphonia severity index was calculated and analyzed. Result:There was no significant difference in age, sex and course of disease between the two groups (P> 0.05).Compared with pre-treatment, RSI, RFS, Jitter, Shimmer, G and R in two groups decreased significantly after treatment, and MPT, DSI increased significantly (P<0.05). Before treatment, RSI, RFS, Jitter, Shimmer, G and R in the operation group were significantly higher than those in the non-operation group, and MPT, DSI were lower (P<0.05). There were no significant differences in the parameters between the two groups after treatment (P> 0.05). DSI was negatively correlated with GRBAS scoring parameters, Jitter and Shimmer, and positively correlated with RSI, RFS, and MPT (P<0.01). DSI is related to the location of the lesion (P<0.05) The incidence of anxiety was 27.27% in patients with moderate and severe sudden sensorineural hearing loss, and the incidence of depression was 25.25%. The scores of anxiety and depression were statistically significant (P<0.05). The multivariate logistic regression analysis showed that the status of anxiety and depression was accompanied by symptoms and other diseases (P<0.05). There was a significant difference between the effective group, the significant efficacy group and the cured group (P<0.05). The difference between the scores before and after treatment was compared. Differences in the ineffective group compared with the other three groups, and the cured group compared with the other three groups of anxiety, depression were statistically significant. Conclusion:DSI can be used as an objective evaluation index for the diagnosis and treatment of laryngeal reflux related voice diseases, and it is accurate and reliable.

Abstract
PURPOSE To investigate the relationship between hypothyroidism, hyperthyroidism, thyroid hormone replacement, and the risk of breast cancer. METHODS We searched the PubMed, Cochrane Library, EMbase, Web of Science, and China Biology Medicine (CBM) databases through June 2016 to identify researches that assessed the relationship between thyroid dysfunction and the risk of breast cancer together with the impact of thyroid hormone substitution treatment on incidence of breast cancer. Quality of evidence was assessed per outcome, using GRADE. RESULTS A total of 13 population-based studies including 24,808 participants were identified as eligible for this meta-analysis. A meta-analysis of 12 researches illustrated that hypothyroidism was not related to the risk for breast cancer [odds ratio (OR) = 0.83, 95% confidence interval (CI) 0.64-1.08, P = 0.162]. 10 researches illustrated that hyperthyroidism was also not related to the risk of breast cancer (OR = 1.03, 95% CI 0.83-1.30, P = 0.767). The impact of therapy was evaluated in six researches; there was no proof of a relationship between thyroid hormone substitution treatment and breast cancer with an overall OR of 0.83 (95% CI 0.57-1.21, P = 0.965). CONCLUSIONS Our meta-analysis illustrated that thyroid dysfunction may not be related to increased risk of breast cancer as well as the thyroid hormone substitution treatment did not reduce the incidence of breast cancer; while this study has some confounders that might weaken the results of this meta-analysis, we believe that the findings provide valuable information for stakeholders concerned with outcomes in patients with thyroid dysfunction.

Abstract
OBJECTIVE To assess the diagnostic rate, safety and clinical application of percutaneous renal masses biopsy for advanced renal cell carcinoma patients. METHODS In this retrospective study, we collected the data of renal masses from the patients who underwent renal masses biopsy under ultrasound from April 2001 to December 2014 in Peking University First Hospital. A total of 75 patients who were undiagnosed or diagnosed with advanced renal cell carcinoma by the imageological method were enrolled in this study. The patient and lesion characteristics such as tumor size, pathology of tumor, histologic subtype, pathological grade, biopsied location and biopsied cores were recorded and analyzed. RESULTS Among all the 75 patients, biopsy was diagnostic in 64 cases (85.3%) and non-diagnostic in 11 cases (14.7%). Of the 64 diagnostic biopsies, 60 were malignant, including 37 (61.7%) renal cell carcinoma (RCC), 13 (21.7%) urothelial carcinoma and 10 (16.7%) other malignant masses. Of all the RCC subjects, 24 suffered from clear cell RCC, 5 papillary RCC, 3 collecting duct carcinomas, 1 unclassified RCC and 4 unknown subtypes. The 11 non-diagnostic biopsied samplings included inflammatory, blood and extrarenal tissue and normal renal tissue. The proportion of collecting duct carcinoma in RCC was 10.8% and the proportion of squamous carcinoma in urothelial carcinoma was 23.1%, which were both higher than the previous research findings. For the male and female groups, non-diagnostic yields were 6.5% and 30.4%, respectively (P=0.022). Of all the 75 patients, 13 renal cell carcinoma patients underwent the surgical treatment and got the results of postoperative pathology. Comparing preoperative biopsy pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rates for benign and malignant lesions, pathological subtype and pathological grade were 100%, 81.8% and 60%, respectively. Mild macroscopic hematuria occurred in 1 case after RMB and there were no serious complications in all the cases. CONCLUSION Percutaneous renal masses biopsy under ultrasound with a high diagnostic rate which can define the histologic subtype of renal cell carcinoma. With targeted therapy, more and more patients whose evaluation suggests local advanced disease or metastatic tumors adopt renal tumor biopsy to define the histologic subtype, which could avoid unnecessary surgical treatment.

Abstract
OBJECTIVE To study elderly hypertensive patients with trace albuminuria (urine albumin to creatinine ratio (UACR)) and the relationship between the occurrence of new cardiovascular events, to provide a basis for early prevention in elderly patients with high blood pressure. PATIENTS AND METHODS A total of 3564 elderly patients with high blood pressure were enrolled in the study. Based on UACR, patients were divided into four groups (group A: 0.05-3.20 mg/g; group B:3.21-10.04 mg/g; group C: 10.05-19.33 and group D: 19.34-30.00 mg/g). All patients underwent follow-up for an average period of 3.8 years. Four groups were compared for new cardiovascular events and they were correlated with UACR. RESULTS Through multivariate Cox proportional hazards regression analysis, the relative risk of cardiocerebrovascular events, cerebral infarction, and acute myocardial infarction (mi), in group D was 1.74 times (p < 0.05), 1.66 times (p < 0.05), and 2.48 times (p < 0.05), respectively. UACR level in females and those with higher age, body mass index, systolic blood pressure, fasting blood glucose, TG, TC, LDL-C levels and lower HDL-C were higher. During follow-up, patients from group D with sudden cardiac death, acute myocardial infarction, cerebral hemorrhage, cerebral infarction occurrence was significantly higher than group A (χ2 = 79.3, p = 79.3) CONCLUSIONS: According to UACR level, we can perform early prevention for elderly patients with high blood pressure, thus reducing the occurrence of cerebral infarction and myocardial infarction.
