Abstract
Objective: To investigate the role and mechanism of COL11A1 in lung adenocarcinoma migration and invasion. Methods: Surgical pathological tissues of 4 patients with lung adenocarcinoma admitted to the Affiliated Hospital of Guizhou Medical University from September to November 2020 were used. Immunohistochemical methods were used to identify lung adenocarcinoma tissues, para-cancerous tissues and parallel transcriptome sequencing. Genetic prognostic analysis was conducted by TCGA and GTEx databases.The expression level of COL11A1 gene in lung adenocarcinoma and adjacent tissues was detected by Western blotting.The primary human lung adenocarcinoma cells cultured. The COL11A1 siRNA was transfected into primary human lung adenocarcinoma cells, then the transcriptome sequencing of differential genes was performed,and KEGG enrichment analysis of differential gene enrichment pathway was conducted. Protein expression and phosphorylation were detected by Western blot method. Cell migration was detected by scratch healing test. Cell proliferation was detected by CCK8 method and invasion ability was detected by Transwell method. Results: Ten differentially expressed genes were screened by transcription sequencing in lung adenocarcinoma. Prognostic analysis of single gene showed that COL11A1 gene expression level was correlated with survival rate (P<0.001). The expression of COL11A1 in lung adenocarcinoma was higher than that in adjacent tissues by Western blot (P<0.001). Transcriptome sequencing of COL11A1 siRNA transfection into primary human lung adenocarcinoma cells showed that differential genes were concentrated in PI3K-akt pathway. The expression of tumor suppressor gene PTEN in siRNA transfection group was significantly higher than that in control group and negative transfection group by Western blot. The expression of Aktp-Akt 473 p-Akt 308 p-PTENp-PDK1p-c-Rafp-GSK-3 β was down-regulated (all P<0.05).Compared with the negative control group, the ability of migration, proliferation and invasion of primary human lung adenocarcinoma cells in siRNA transfection group decreased (all P<0.05). COL11A1 regulates PI3K/Akt/GSK-3 β pathway to promote migration and invasion of primary human lung adenocarcinoma cells. Conclusion: COL11A1 regulates PI3K/Akt/GSK-3 β pathway to promote migration and invasion of primary human lung adenocarcinoma cells.

Abstract
BACKGROUND We aimed to examine whether patients with de novo and relapsed/progressed stage IIIB-IV non-small cell lung cancer (NSCLC) without epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) mutations have different prognoses. METHODS This retrospective study analyzed the Health Insurance Review and Assessment claims data in South Korea from 2013 to 2020. Patients with stage IIIB-IV NSCLC without EGFR or ALK mutations who received first-line palliative therapy between 2015 and 2019 were identified. Overall survival (OS), time to first subsequent therapy (TFST), and time to second subsequent therapy (TSST) were estimated using the Kaplan-Meier method. Multivariate Cox regression analysis was used to reveal the impact of de novo versus relapsed/progressed disease on OS. Treatment patterns, including treatment sequence, top five most frequent regimens, and time to treatment discontinuation, were described in both groups. RESULTS Of 14,505 patients, 12,811 (88.3%) were de novo, and 1,694 (11.7%) were relapsed/progressed. The median OS in the de novo group was 11.0 versus 11.5 months in the relapsed/progressed group (P = 0.002). The ongoing treatment probability was higher in relapsed/progressed patients than in de novo patients from 6.4 months since the initiation of first-line treatment (P < 0.001). Median TSST was shorter in the de novo group than in the relapsed/progressed group (9.5 vs. 9.9 months, P < 0.001). In multivariate analysis, de novo disease was associated with shorter OS (hazard ratio 1.07; 95% confidence interval 1.01-1.14). The overall treatment patterns for de novo and relapsed/progressed patients were similar. CONCLUSIONS De novo patients had poorer OS and TSST after the initiation of palliative therapy than relapsed/progressed patients. These findings suggest that the stage of the disease at the time of initial diagnosis should be considered in observational studies and clinical trials as a prognostic factor.

Abstract
This study attempted to investigate whether exosomes derived from rat endothelial cells (EC-Exo) attenuate intimal hyperplasia after balloon injury using hematoxylin and eosin staining, immunohistochemistry, immunofluorescence staining, Evans blue staining, and Western blotting. The results indicated that EC-Exo inhibited intimal hyperplasia in the carotid artery after balloon injury, promoted re-endothelialization, and reduced vascular inflammation and ROS-NLRP3-mediated cell pyroptosis. Thus, EC-Exo can inhibit neointimal hyperplasia after carotid artery injury in rats presumably by inhibiting the ROS-NLRP3 inflammasome and phenotypic transformation of vascular smooth muscle cells.

Abstract
Objective: To analyze the phenotypic-genotypic characteristics of hereditary deafness caused by OTOA gene variations. Methods: Family histories, clinical phenotypes and gene variations of six pedigrees were analyzed, which were diagnosed with hearing loss caused by OTOA gene variations at the PLA General Hospital from September 2015 to January 2022. The sequence variations were verified by Sanger sequencing and the copy number variations were validated by multiplex ligation-dependent probe amplification (MLPA) in the family members. Results: The hearing loss phenotype caused by OTOA variations ranged from mild to moderate in the low frequencies, and from moderate to severe in the high frequencies in the probands, which came from six sporadic pedigrees, among which a proband was diagnosed as congenital deafness and five were diagnosed as postlingual deafness. One proband carried homozygous variations and five probands carried compound heterozygous variations in OTOA gene. Nine pathogenic variations (six copy number variations, two deletion variations and one missense variation) and two variations with uncertain significance in OTOA were identified in total, including six copy number variations and five single nucleotide variants, and three of the five single nucleotide variants were firstly reported [c.1265G>T(p.Gly422Val),c.1534delG(p.Ala513Leufs*11) and c.3292C>T(p.Gln1098fs*)]. Conclusions: OTOA gene variations can lead to autosomal recessive nonsyndromic hearing loss. In this study, the hearing loss caused by OTOA defects mostly presents as bilateral, symmetrical, and postlingual, and that of a few presents as congenital. The pathogenic variations of OTOA gene are mainly copy number variations followed by deletion variations and missense variations.

Abstract
The coexistence of gate-tunable superconducting, magnetic and topological orders in magic-angle twisted bilayer graphene provides opportunities for the creation of hybrid Josephson junctions. Here we report the fabrication of gate-defined symmetry-broken Josephson junctions in magic-angle twisted bilayer graphene, where the weak link is gate-tuned close to the correlated insulator state with a moiré filling factor of υ = -2. We observe a phase-shifted and asymmetric Fraunhofer pattern with a pronounced magnetic hysteresis. Our theoretical calculations of the junction weak link-with valley polarization and orbital magnetization-explain most of these unconventional features. The effects persist up to the critical temperature of 3.5 K, with magnetic hysteresis observed below 800 mK. We show how the combination of magnetization and its current-induced magnetization switching allows us to realise a programmable zero-field superconducting diode. Our results represent a major advance towards the creation of future superconducting quantum electronic devices.

Abstract
Greek yogurt is a strained yogurt with a high protein content that brings nutritional benefits. To enhance the functional benefits of Greek yogurt, Greek yogurt was prepared with various combinations of probiotic lactic acid bacteria (LAB) (Streptococcus thermophilus, Lactobacillus bulgaricus, Lactobacillus gasseri BNR17, and Lactobacillus plantarum HY7714). Effects of probiotic LAB on quality, sensory, and microbiological characteristics of Greek yogurt were then compared. Among samples, Greek yogurt fermented by S. thermophilus and L. bulgaricus showed the highest changes of pH and titratable acidity during 21 d of storage at 4 °C. Greek yogurt fermented with L. plantarum HY7714 had a higher viscosity than other samples. Greek yogurt fermented with S. thermophilus, L. bulgaricus, L. gasseri BNR17, and L. plantarum HY7714 showed superior physicochemical properties and received the highest preference score from sensory evaluation among samples. Overall, the population of enterohaemorrhagic Escherichia coli (EHEC) was more effectively reduced in Greek yogurt fermented with probiotic LAB than in commercial Greek yogurt during storage at 4, 10, and 25 °C. Thus, the addition of L. gasseri BNR17 and L. plantarum HY7714 as starter cultures could enhance the microbial safety of Greek yogurt and sensory acceptance by consumers.

Abstract
To evaluate the safety of the domestic 13-valent pneumococcal polysaccharide conjugate vaccine-tetanus toxoid protein (PCV13-TT) after its licensure. The adverse event following immunization (AEFI) and the vaccination data of PCV13-TT in Zhejiang province from July 2020 to October 2021 were collected from national adverse event following immunization surveillance system and Zhejiang provincial immunization information system. Descriptive epidemiological method was used for this analysis. From July 2020 to October 2021, 302 317 doses of PCV13-TT were administered in children under 6 years old in Zhejiang Province and 636 AEFI case reports were received, with a reporting rate of 21.04 per 10 000 doses. Of these AEFI cases, 97.17% were mild vaccine product-related reaction (20.54 per 10 000 doses) and 95.44% occurred in the 0-1 d after vaccination (20.08 per 10 000 doses). The most common clinical diagnoses of AEFI included fever (224 cases), redness (204 cases), and induration (190 cases), while allergic rash (11 cases) was the most common diagnosis among the abnormal reactions. In conclusion,the present results bolstered that the domestic PCV13-TT was generally well tolerated in children under 6 years old in Zhejiang Province.

Abstract
Oral squamous cell carcinoma (OSCC) is prevalent around the world and is associated with poor prognosis. OSCC is typically diagnosed from tissue biopsy sections by pathologists who rely on their empirical experience. Deep learning models may improve the accuracy and speed of image classification, thus reducing human error and workload. Here we developed a custom-made deep learning model to assist pathologists in detecting OSCC from histopathology images. We collected and analyzed a total of 2,025 images, among which 1,925 images were included in the training set and 100 images were included in the testing set. Our model was able to automatically evaluate these images and arrive at a diagnosis with a sensitivity of 0.98, specificity of 0.92, positive predictive value of 0.924, negative predictive value of 0.978, and F1 score of 0.951. Using a subset of 100 images, we examined whether our model could improve the diagnostic performance of junior and senior pathologists. We found that junior pathologists were able to delineate OSCC in these images 6.26 min faster when assisted by the model than when working alone. When the clinicians were assisted by the model, their average F1 score improved from 0.9221 to 0.9566 in the case of junior pathologists and from 0.9361 to 0.9463 in the case of senior pathologists. Our findings indicate that deep learning can improve the accuracy and speed of OSCC diagnosis from histopathology images.

Abstract
Objective: To estimate the incidence of metabolic syndrome and explore possible risk factors for metabolic syndrome in adults of rural communities in Yuhuan county, Zhejiang province, China. Methods: During June-December, 2018, a follow-up survey was conducted in participants without metabolic syndrome at baseline survey in 2012 to obtain the information collected in questionnaire survey, anthropometric data and laboratory data. The incidence of metabolic syndrome in the participants was estimated, and Logistic regression model was used to explore the risk factors, adjusted risk ratio (aRR) and 95%CI. Results: Among 3 162 participants, 522 new metabolic syndrome cases were identified. The 6-year cumulative incidence rate of metabolic syndrome was 16.5%, and the cumulative incidence rate was higher in women (20.6%) than that in men (12.3%, P<0.001). Those incidence rates were higher in those in jobless, smoking or drinking groups. Being women (aRR=1.96, 95%CI: 1.50-2.58) and family history of hypertension (aRR=1.31, 95%CI: 1.04-1.63) were independent risk factors for metabolic syndrome. Conclusion: The follow up indicated that the incidence of metabolic syndrome was relatively high in rural adults on islands in Zhejiang, and women or those with family history of hypertension were more likely to have metabolic syndrome.

Abstract
Few studies assessed the association between major adverse cardiovascular events and adherence to warfarin and direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF). Therefore, we aimed to evaluate the effects of adherence to oral anticoagulants (OACs) in patients with AF using claims data (July 2014–April 2019). Using the initial 3-month medication possession rate (MPR), patients were categorized into adherent (MPR ≥ 0.8) or non-adherent (MPR < 0.8) groups. Propensity score matching of non-adherent group to adherent group was conducted for warfarin (1:1) and DOAC (1:3), respectively. Incidence of ischemic stroke, myocardial infarction (MI), intracranial hemorrhage, and all-cause death was assessed in the matched cohort (67,147 patients). The hazard ratio (HR) for adherence to OAC was estimated using the Cox proportional hazard model with adjusting covariate including age and sex. The risk for ischemic stroke, MI, and all-cause death was lower in the DOAC adherent group than in the DOAC non-adherent group (HR: 0.78; 95% confidence intervals: 0.73–0.84; 0.75, 0.60–0.94; 0.54, 0.51–0.57, respectively). Adherence to OAC was not associated with the risk of intracranial hemorrhage (1.01, 0.85–1.20). Commitment programs to improve adherence in patients with AF could maximize drug effectiveness and safety.

Abstract
Mitochondrial DNA copy number (mtDNA-CN) measured from blood specimens is a minimally invasive marker of mitochondrial function that exhibits both inter-individual and intercellular variation. To identify genes involved in regulating mitochondrial function, we performed a genome-wide association study (GWAS) in 465,809 White individuals from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and the UK Biobank (UKB). We identified 133 SNPs with statistically significant, independent effects associated with mtDNA-CN across 100 loci. A combination of fine-mapping, variant annotation, and co-localization analyses was used to prioritize genes within each of the 133 independent sites. Putative causal genes were enriched for known mitochondrial DNA depletion syndromes (p = 3.09 × 10-15) and the gene ontology (GO) terms for mtDNA metabolism (p = 1.43 × 10-8) and mtDNA replication (p = 1.2 × 10-7). A clustering approach leveraged pleiotropy between mtDNA-CN associated SNPs and 41 mtDNA-CN associated phenotypes to identify functional domains, revealing three distinct groups, including platelet activation, megakaryocyte proliferation, and mtDNA metabolism. Finally, using mitochondrial SNPs, we establish causal relationships between mitochondrial function and a variety of blood cell-related traits, kidney function, liver function and overall (p = 0.044) and non-cancer mortality (p = 6.56 × 10-4).

Abstract
Abstract
Background
With advancement in computational fluid dynamics (CFD) technology, novel lesion-specific hemodynamic parameters can be estimated non-invasively. However, their long-term prognostic implications have not been fully defined.
Purpose
We sought to investigate the ten-year outcomes of lesion-specific hemodynamic indices derived-from coronary CT angiography (CCTA).
Methods
A total of 145 vessels (95 patients) with stable coronary artery disease who underwent fractional flow reserve (FFR) derived by coronary computed tomographic angiography (FFRCT) and invasive FFR measurement was included from the first-in-human study of FFRCT. Study participants were enrolled from October 2009 to January 2011 and were followed up until December 2020. A total of 340 lesions with % diameter stenosis ≥30% were identified, and wall shear stress (WSS) and change FFRCT across the lesion (ΔFFRCT) were obtained using CFD techniques by an independent core laboratory. The optimal cut-off for WSS and ΔFFRCT was applied for outcome analysis. The primary endpoint was target lesion failure (TLF) including cardiovascular death, target vessel myocardial infarction, and target lesion revascularization at 10 years.
Results
The median WSS and ΔFFRCT was 183.3 [112.8; 273.9] and 0.06 [0.03; 0.13]. WSS and ΔFFRCT was mildly correlated with FFRCT (r=−0.18, P=0.001 for WSS; r=−0.36, P<0.001 for ΔFFRCT). Of 179 lesions with deferral of revascularization at the index procedure of FFR measurement, TLF occurred in 16 (8.9%) lesions. In prediction of 10-year TLF, % diameter stenosis (per-lesion) ≥50%, FFRCT ≤0.80, WSS ≥256.1 dyn/cm2, and ΔFFRCT ≥0.06 were significant predictors. However, in multivariate analyses with those predictors, % diameter stenosis (per-lesion) ≥50%, FFRCT ≤0.80 became insignificant, and lesion-specific hemodynamic indices were only predictive of 10-year TLF (adjusted hazard ratio [aHR] 2.66, 95% confidence interval [CI] 0.98–7.22, P=0.055 for WSS ≥256.1 dyn/cm2; aHR 5.88, 95% CI 1.10–33.25, P=0.045 for ΔFFRCT ≥0.06). WSS ≥256.1 dyn/cm2 and ΔFFRCT ≥0.06 had higher information gain in predicting outcomes than % diameter stenosis (per-lesion) ≥50% and FFRCT ≤0.80, and both improved predictability for 10-year TLF risk of the model with % diameter stenosis (per-lesion) ≥50% and FFRCT ≤0.80 (P=0.068 for WSS ≥256.1 dyn/cm2; P=0.011 for ΔFFRCT ≥0.06) (Figure).
Conclusions
Non-invasive lesion-specific hemodynamic indices (i.e., high WSS and high ΔFFRCT) were the robust predictors of 10-year outcomes of a target lesion with incremental predictability over anatomical severity and low FFRCT. Clinical application of non-invasive hemodynamic indices will provide better long-term risk stratification over the current prognostication scheme before an invasive procedure.

Introduction
The risk of procedure-related complications and rhythm outcomes differ between men and women after atrial fibrillation catheter ablation (AFCA). We evaluated whether consistent sex differences existed in mapping and rhythm outcomes in repeat ablation procedures.
Methods
Among 3,282 patients in the registry, we analysed 443 consecutive patients (24.6% female, 58.5 ± 10.3 years old, 61.5% paroxysmal AF) who underwent a second AFCA. We compared the clinical factors, mapping, left atrial (LA) pressure, complications, and long-term clinical recurrences after propensity score matching.
Results
The LA volume index (43.1 ± 18.6 vs. 35.8 ± 11.6 ml/m2, p < 0.001) was higher, but LA dimension (40.0 ± 6.8 vs. 41.6 ± 6.3mm, p = 0.018), LA voltage (0.94 ± 0.55 vs. 1.20 ± 0.68 mV, p = 0.002), and pericardial fat volume (89.5 ± 43.1 vs. 122.1 ± 53.9 cm3, p < 0.001) lower in women with a repeat ablation than in their male counterparts. The pulmonary vein (PV) reconnections were lower (58.7% vs. 74.9%, p = 0.001), but the proportion of extra-PV triggers (27.5% vs. 17.0%, p = 0.026) and elevated LA pulse pressures (79.7% vs. 63.7%, p = 0.019) was significantly higher in women than men. There was no significant sex difference in the procedure-related complication rate (4.6% vs. 4.2%, p = 0.791). During a 31(8∼60) month median follow-up, clinical recurrences were significantly higher in women after both the de novo procedure (log rank p = 0.039, antiarrhythmic drug [AAD]-free log rank p < 0.001) and second procedure (log rank p = 0.006, AAD-free log rank p = 0.093). A female sex (HR 1.51 [1.06-2.15], p = 0.023), non-paroxysmal AF (HR 1.78 [1.30-2.34], p < 0.010), and extra-PV triggers (HR 1.88 [1.28-2.75], p = 0.001) were independently associated with clinical recurrences after repeat procedures.
Conclusions
During the repeat AFCA procedures, PV reconnections were lower in women than men, and the existence of extra-PV triggers and an LA pressure elevation was more significant, which resulted in poor rhythm outcomes.

Abstract
OBJECTIVE To explore differences in end-of-life healthcare utilisation and medication costs between patients with haematological malignancies and patients with solid tumours. METHODS Data on deceased patients with cancer were selected from the sample cohort data of health insurance claims from 2008 to 2015 in South Korea. They were categorised into two groups: patients with haematological malignancies and patients with solid tumours. Longitudinal data comprised the patient-month unit and aggregated healthcare utilisation and medication cost for 1 year before death. Healthcare utilisation included emergency room visits, hospitalisation and blood transfusions. Medication costs were subdivided into anticancer drugs, antibiotics, opioids, sedatives and blood preparation. Generalised linear mixed models were used to evaluate differences between the two groups and time trends. RESULTS Of the 8719 deceased patients with cancer, 349 died from haematological malignancies. Compared with solid tumours, patients with haematological malignancies were more likely to visit the emergency room (OR=1.36, 95% CI 1.10 to 1.69) and receive blood transfusions (OR=5.44, 95% CI 4.29 to 6.90). The length of hospitalisation of patients was significantly different (difference=2.49 days, 95% CI 1.75 to 3.22). Medication costs, except for anticancer treatment, increased as death approached. The costs of antibiotics and blood preparations were higher in patients with haematological malignancies than in those with solid tumours: 3.24 (95% CI 2.14 to 4.90) and 4.10 (95% CI 2.77 to 6.09) times higher, respectively. CONCLUSIONS Patients with haematological malignancies are at a higher risk for aggressive care and economic burden at the end of life compared with those with solid tumours. Detailed attention is required when developing care plans for end-of-life care of haematological patients.

Abstract
Objective: To screen out and explore the core gene (Hub gene) involvement and the potential role of cyclin B2 (CCNB2) in the development and prognosis of hepatocellular carcinoma (HCC) through bioinformatics methods. Methods: Four HCC-related datasets were screened, and downloaded from the GEO database. GEO2R tool was used to analyze data and identify the differentially expressed genes (DEGs). Gene Ontology (GO) and KEGG signal pathway enrichment analysis were completed using DAVID database and Cytoscape (ClueGO) plug-in, respectively. Protein-protein interaction network (PPI) of DEGs was established using the STRING database. Cytoscape software was used to visualize PPI network, key modules (cluster) construction and core genes identification. UCSC and UALCAN database were used to analyze the differential expression and survival of TCGA hepatocellular carcinoma core genes. Firebrowse, Oncomine and UALCAN databases were used to analyze the expression of core genes in multiple tumors including HCC. Real-time quantitative reverse transcription PCR (RT-qPCR) was used to detect the expression levels of candidate genes in HCC tissues and liver cancer cell lines. Results: A total of 73 DEGs were identified from the four datasets, including 15 up-regulated genes and 58 down-regulated genes. KEGG pathway enrichment analysis signal showed that DEGs were mainly enriched in tumor-related pathways. PPI network based on DEGs had screened the key modules and 10 core genes. CCNB2 and NCAPG were highly expressed in liver cancer tissues in multiple databases. CCNB2 was positively correlated with NCAPG and was considered as a key gene related to prognosis (P < 0.01). RT-qPCR results showed that CCNB2 was highly expressed in human HCC tissues and cell lines (P < 0.01). Conclusion: Successfully screened DEGs and core genes related to HCC. Among them, CCNB2 is highly expressed in HCC and is related to the survival and prognosis of patients, so it is expected to become a biomarker for the diagnosis and prognosis of HCC.

Abstract
OBJECTIVES Recognizing the value of anticancer treatments based on progression-free survival and overall survival may help decision making in healthcare policy. We aimed to measure and compare the impact of disease progression and terminal state prior to death on healthcare costs in HR+, HER2- ABC patients. METHODS We conducted a retrospective study using Korean nationwide health insurance claims database between 1 September 2012 and 31 August 2017. The impact of disease progression was estimated by measuring the average incremental monthly cost per patient during 1 year after progression compared to 1 year before progression. Death-related costs per patient per month (PPPM) were measured for those who died within 1 year after progression. Generalized estimating equation (GEE) was used to estimate the variations in PPPM costs by progression and death with adjustment for clinical factors. RESULTS After progression, 1,636 patients expensed $2,892 per month more on average than before progression ($3762 vs. $870). The GEE analysis with adjustment for baseline characteristics showed that PPPM costs increased by 3.46 folds (95% CI = 3.06-3.93) after progression. Also, PPPM costs were 1.74 (95%CI = 1.43-2.12) times higher in patients who died within 1 year after progression relative to survived patients. When considering the interaction between progression and death, deceased patients showed higher increased ratio of PPPM costs after progression (4.91; p=value<.0001) than survived patients (2.95; 95% CI = 2.61-3.34). CONCLUSIONS From the payer's perspective, more healthcare costs incurred during the progression state than terminal state in HR+, HER2- ABC patients. The impact of disease progression emphasizes the importance of effectively treating HR+, HER2- ABC patients.

Abstract
Objective: To evaluate lower facial profile in females in different skeletal patterns. Methods: Investigation pictures of three females with beautiful lower facial profiles from Department of Orthodontics, Henan Stomatological Hospital were collected. The skeletal patterns of these females were classified as average, low and high angle, respectively.Upper lip process point (UL) was moved backwards horizontally to reach towards the E line and go even further gradually in above pictures. The distance changed according to E line was defined as DE value. If UL was in front of E line,DE value was denoted as positive, or else negative. Collectively, we obtained 30 pictures (10 pictures in each skeletal facial type) with different DE values (-5, -4, -3, -2, -1, 0, 1, 2, 3, 4 mm), which were divided into average, low and high angle group according to the skeletal facial type. The pictures were evaluated by 144 randomly-selected adult orthodontic patients [66 males, 78 females, aged (29.4±7.7) years] who visited Department of Orthodontics, Henan Stomatological Hospital from June to September, 2019 and 138 orthodontists (including qualified orthodontists and postgraduate orthodontic students [60 males, 78 females, aged (32.2±7.1) years] who participated orthodontics conferences in Henan Stomatological Hospital in June, 2019. The acceptance rate was calculated and rate above 60% was deemed as acceptable DE range. Evaluators were also asked to choose the most esthetic profiles for the best DE value in each skeletal facial type.Data discrepancy was analyzed using Kruskal-Wallis analysis and chi-square test. Results: Most accepted DE was -2 mm among total investigators including orthodonticpatients and orthodontists. There was no difference in total acceptance rate between orthodontists and patients (P>0.05). There was statistic difference in total acceptance rate in different skeletal patterns between orthodontic patients and orthodontists (P<0.05). In total investigators, total acceptance rate was 62.1% (1 752/2 820) in average angle group, 55.4%(1 563/2 820) in high angle group and 33.5%(946/2 820) in low angle group, respectively. Acceptable DE range in three facial types was -4~2 mm (average angle), -2~2 mm (high angle) and -2~-1 mm (low angle), respectively. Conclusions: According to the evaluation of both orthodontic patients and orthodontists, the best DE was-2 mm.Total acceptance rate and acceptable DE range ranked first in average angle group, second in high angle group and third in low angle group.

Abstract
AIM To evaluate the antibiofilm effect of proanthocyanidin (PA) solution as an irrigant against Enterococcus faecalis (E. faecalis) and its influence on the mechanical properties and biodegradation resistance of demineralized root dentine. METHODOLOGY Enterococcus faecalis were introduced into human root dentine tubules by a serial centrifugation method and grown for 1 week. Dentine blocks infected with 1-week-old E. faecalis biofilms were treated with the following irrigants: sterile water (control), 2% chlorhexidine (CHX), 2% PA, 5% PA and 10% PA. After treatment, the live and dead bacteria proportions within E. faecalis biofilms were analysed using confocal laser scanning microscopy. To evaluate the biostability of fully demineralized dentine treated by the aforementioned irrigants, the elastic modulus and hydroxyproline release of human dentine incubated in collagenase solution were tested at baseline, after irrigant treatment and after biodegradation, respectively. Furthermore, the surface chemical bond of demineralized dentine collagen treated by various irrigants was characterized by X-ray photoelectron spectroscopy (XPS). Statistical analysis was performed using one-way anova and Tukey's post hoc multiple comparisons with the significance level at 5%. RESULTS The proportion of dead E. faecalis volume was significantly higher in the PA and CHX groups than that in the control group (P < 0.05). PA irrigation significantly increased the mechanical properties of demineralized dentine (P < 0.05), and the effect was enhanced with increasing PA concentration. CHX and PA groups had significantly less elasticity loss and hydroxyproline release (P < 0.05). The biomodification of dentine collagen by PA was verified by increased C-O/C-N peak percentage under C1s and C-O peak percentage under O1s narrow-scan XPS spectra. CONCLUSIONS Proanthocyanidin killed E. faecalis within biofilms and enhanced the biostability of the collagen matrix of demineralized root dentine. It might be used as an auxiliary endodontic irrigant with antibiofilm and collagen-stabilizing effects.

Abstract
Objective: To isolate a bacteriophage against pan-drug resistant Klebsiella pneumoniae in a burn patient, and to study its biological characteristics, genomic information, and effects on bacterial biofilm. Methods: (1) In 2018, pan-drug resistant Klebsiella pneumoniae UA168 (hereinafter referred to as the host bacteria) solution isolated from the blood of a burn patient in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine (hereinafter referred to as Ruijin Hospital) was used to isolate and purify the bacteriophage against pan-drug resistant Klebsiella pneumoniae from the sewage of Ruijin Hospital with sewage co-culture method, drip plate method, and double-agar plate method. The bacteriophage was named as phage KP168 and the plaque morphology was observed. (2) The phage KP168 solution was taken for cesium chloride density gradient centrifugation and dialysis, and then the morphology of phage KP168 was observed through transmission electron microscope after phosphotungstic acid negative staining. (3) The phage KP168 solution was taken to determine the lytic ability of the phage KP168 against 20 strains of pan-drug resistant Klebsiella pneumoniae isolated from the burned patients' blood in Ruijin Hospital by the drip plate method, and then the lysis rate was calculated. (4) The phage KP168 solution at a initial titer of 9.3×10(11) plaque-forming unit (PFU)/mL (400 μL per tube) and the host bacteria solution at a concentration of 1×10(9) colony-forming unit (CFU)/mL (4 mL per tube) were conventionally shaking cultured together for 4 hours at multiplicity of infection (MOI) of 10.000, 1.000, 0.100, 0.010, or 0.001, respectively (1 tube per MOI). The titer of phage KP168 was measured by the double-agar plate method (the measurement method was the same below) to select the optimal MOI. The experiment was repeated three times. (5) The host bacteria solution at a concentration of 1×10(9) CFU/mL (4 mL per tube) and the phage KP168 solution at an adjusted titer of 5×10(7) PFU/mL (400 μL per tube) were mixed at the MOI of 0.005. The plaques were counted 0 (immediately), 1, 2, 3, 4, 5, 15, and 30 minutes (1 tube at each time point) after mixing by the double-agar plate method (the counting method was the same below), and the percentage of adsorbed phages was calculated to screen for the optimal adsorption time. The experiment was repeated three times. (6) The host bacteria solution at a concentration of 1×10(9) CFU/mL (300 μL per tube) and the phage KP168 solution at a titer of 5×10(8) PFU/mL (60 μL per tube) were mixed at MOI of 0.005 and conventionally shaking cultured after standing for the optimal adsorption time. The phage KP168 titer was measured 0 (immediately), 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 minutes after culture, and a one-step growth curve was drawn. The experiment was repeated three times. (7) The phage KP168 solution at a titer of 2.5×10(10) PFU/mL was left to stand for 1 hour at 37, 40, 50, 60, or 70 ℃ (3 tubes at each time point, 1 mL per tube) for counting the plaques, and then the thermal stability curve was drawn. SM buffer at a pH values of 5.0, 6.0, 7.0, 7.4, 8.0, 9.0, or 10.0 were added to the phage KP168 solution at a titer of 3.0×10(10) PFU/mL, respectively. The mixed solution was left to stand for 1 hour at 37 ℃ (3 tubes of each pH, each tube containing 100 μL phage KP168 solution and 900 μL SM buffer), and then the plaques were counted, and an acid-base stability curve was drawn. (8) The phage KP168 solution was taken for DNA extraction and sequencing after dialysis as in experiment (2). The whole genome was annotated with Prokka to obtain the coding sequence of phage KP168. Nucleotide's BLAST function was used to proceed nucleic acid sequence alignment for finding a known phage with the highest similarity to the phage KP168 nucleic acid sequence, and Blastx function was used to translate the coding sequence into protein for its function prediction. The comparison with Antibiotic Resistance Genes Database and Virulence Factors Database was proceeded. (9) In a 96-well plate, at a MOI of 1.000, 0.100, 0.010 or 0.001 (3 wells per MOI), 20 μL phage KP168 solution at a initial titer of 5.8×10(10) PFU/mL was added to 200 μL host bacteria solution at a concentration of 1.5×10(8) CFU/mL (the same concentration below) for co-cultivation for 48 hours. After 200 μL host bacteria solution was left to stand for 48 hours, 20 μL phage KP168 solution at a titer of 1×10(6,) 1×10(7,) 1×10(8,) 1×10(9,) or 1×10(10) PFU/mL (3 wells per titer) was added respectively for action for 4 hours. In both experiments, 200 μL host bacteria solution added with 20 μL SM buffer (3 wells) acted as a negative control, and 220 μL LB culture medium (3 wells) acted as a blank control. Absorbance values were measured by a microplate reader, and inhibition/destruction rates of biofilm were calculated. The experiments were both repeated three times. Results: (1) The plaques of phage KP168 successfully isolated and purified were transparent and round, and its diameter was approximately 1.5 mm. (2) The phage KP168 has a regular polyhedron structure with a diameter of about 50 nm and without a tail. (3) The phage KP168 could lyse 13 of 20 strains of Klebsiella pneumoniae from burned patients, with a lysis rate of 65.0%. (4) When MOI was 1.000, the titer was the highest after co-culturing the phage KP168 with the host bacteria for 4 hours, which was the optimal MOI. (5) After the mixing of the phage KP168 with the host bacteria for 4 minutes, the percentage of the adsorbed phage reached the highest, which was the optimal adsorption time. (6) The one-step growth curve showed that during the lysis of the host bacteria by phage KP168, the incubation period was about 10 minutes, and the lysis period was about 40 minutes. (7) With the condition of 40 ℃ or pH 7.4, the number of plaques and the activity of phage KP168 reached the highest. (8) The genome of phage KP168 was a linear double-stranded DNA with a length of 40 114 bp. There were 48 possible coding sequences. It had the highest similarity to Klebsiella phage_vB_Kp1. The most similar known proteins corresponding to the translated proteins of coding sequences contained 23 hypothetical proteins and 25 proteins with known functions. No resistance genes or virulence factor genes were found. The GeneBank accession number was KT367885. (9) After 48 hours of co-cultivation of the phage KP168 and the host bacteria at each MOI, the inhibition rates of biofilm were similar, with an average of about 45%. After the phage KP168 with a titer of 1×10(9) PFU/mL acted on the biofilm formed by the host bacteria for 4 h, the destruction rate of biofilm was the highest, reaching an average of 42%. Conclusions: In this study, a bacteriophage against pan-drug resistant Klebsiella pneumoniae from a burn patient, phage KP168, is isolated from sewage, which belongs to the tailless phage. It has a wide host spectrum, short adsorption time, and short incubation period, with certain thermal and acid-base stability. Its genomic information is clear, and it does not contain resistance genes or virulence factor genes. It also has an inhibitory effect on the formation of bacterial biofilm and a destructive effect on the formed bacterial biofilm.

Abstract
SummaryIdiopathic tinnitus is a spontancous sense of hearing under neither external acoustic or electric stimuli,and is one of the common symptoms of otorhinolaryngology. At present,the clinical stages and classification of tinnitus vary among different countries. The examination of tinnitus is also multifaceted, including audiology, imaging, psychology and other tests to find tinnitus for the purpose. There are many treatments for tinnitus, including etiological treatment, counseling, cognitive behavioral therapy, tinnitus masking therapy, tinnitus therapy, hearing aids, cochlear implants, drug therapy, repetitive transcranial magnetic stimulation, electrical stimulation and so on.The above treatment methods have not reached a consensus on the efficacy of tinnitus. In recent years, some technology innovations based on sound have produced personalized treatment schemes for different types of tinnitus,which will inevitably become a hot topic in future research.

Abstract
Objective: To evaluate the clinical value and outcomes of technical improvement of hybrid operatical clipping for large paraclinoid internal carotid artery aneurysms. Methods: A review was conducted on 18 cases of large paraclinoid internal carotid artery aneurysm which were clipped by balloon non-fluoroscopic occlusion of the parent artery via a micro-bone window frontolateral approach in hybrid operating room at Neurosurgery Department of Tianjin Medical University General Hospital from June 2014 to December 2017. There were 8 males and 10 females with age of (63±4) years. There were 6 cases of unruptured aneurysm and 12 cases of ruptured aneurysm of subarachnoid hemorrhage (6 cases of grade Ⅱ, 4 cases of grade Ⅲ and 2 cases of grade Ⅳ in Hunt-Hess classification). Frontolateral approach incision (average length of about 5 cm) and bone window about 3 cm×3 cm were performed. No incision of the neck was needed to expose the internal carotid artery for temporary occlusion. In the operation, the balloon was slowly pushed to the preset position of the internal carotid artery under non-fluoroscopy. The balloon was expanded to block the blood flow of internal carotid artery. Then aneurysm was clipped. The balloon was loosened and retraced to the guiding catheter after clipping. The clipping condition was examined by cerebral angiography. If there was residual aneurysm neck or stenosis of the parent artery, the balloon was pushed under non-fluoroscopy again to temporary occlusion and the clip was adjusted until the aneurysm neck was clamped satisfactorily. Results: Eighteen aneurysms were successfully clipped in hybrid operating room. Fourteen aneurysms showed complete occlusion of the aneurysm neck and no stenosis of the parent artery. Four cases showed residual aneurysm neck after clipping by intraoperative angiography, then aneurysms were clipped satisfy by adjusting the aneurysm clip. The patients were followed up for 3 months to 1 year. Ten patients recovered well (modifed Rankin score (mRS): 0), and 3 patients had no obvious disability (mRS: 1). Two patients with Hunt-Hess grade Ⅲ were slightly disabled (mRS: 2). 1 patients with Hunt-Hess grade Ⅲ were moderately disabled (mRS: 3). 1 patients with Hunt-Hess grade Ⅳ were severely disabled (mRS: 4). One elderly patients with Hunt-Hess grade Ⅳ were seriously disabled (mRS: 5). Conclusions: Application of balloon non-fluoroscopic occlusion clipping for large paraclinoid internal carotid artery aneurysm via a micro-bone window frontolateral approach is safe, effective and minimally invasive.

Abstract
Objective: To evaluate the influence of fracture resistance of endodontically treated teeth with different thickness of ferrule by mechanical fatigue test and static loading test, and so as to provide a reference for the clinical treatment planning. Methods: Fifty bovine incisors were divided into 5 groups by random number table method (n=10). Group A was the control group in which the incisors were prepared without a ferrule design (0 mm). The other four groups (B, C, D, E) were experimental groups, and the thickness of the dentin ferrule prepared for specimens in each group was 0.5, 1.0, 1.5, and 2.0 mm. The height of ferrules in all the specimens was 2 mm. Cyclic fatigue loading (2.33 Hz, 50 N) was applied on each specimen until either the specimen was dislodged/fractured or the 300 000 cycles were finished. After fatigue loading, the mode of failure was observed. Those intact specimen after fatigue loading were tested under a gradually increasing force using a universal testing machine (0.05 mm/min) until fracture occurred. The forces required to fracture and failure model was recorded. Results: The results of cyclic loading tests showed that: all specimens survived the 300 000 cycles of intermittent loading. The results of static loading tests showed that: the fracture force of A, B, C, D and E groups respectively were (226.4±67.7), (369.7±34.5), (400.7±48.2), (528.1±56.3), and (555.4±98.5) N (F=15.227, P=0.000). There was a significant difference in fracture resistance between group A and the other four groups, and between group B, C and group D, E (P<0.05). No statistical difference were found in fracture resistance among the other groups (P>0.05). There was strong correlation between the thickness of ferrule and the fracture force by Pearson correlation analysis (r=0.973, P=0.002). Conclusions: Within the limitations of this study, the following conclusions can be drawn: The different thickness of ferrule can influence the fracture resistance of the teeth, and when the height of the ferrule is 2.0 mm, the fracture force increased significantly with an increasing ferrule thickness.

Abstract
OBJECTIVES Asthma exacerbation, associated with many risks factors, can reflect management failure. However, little is known about how risk factors are associated with exacerbation, according to asthma severity. We aimed to investigate differences in risk factors in patients with different asthma severity and evaluate whether risk factors differed between frequent exacerbators and patients with single exacerbation. DESIGN Nationwide population-based observational study. SETTING Korean National Sample Cohort database. PARTICIPANTS We included 22 130 adults with asthma diagnoses more than twice (ICD-10 (International Classification of Diseases, Tenth revision) codes J45 and J46) and one prescription for asthma medication from 2010 to 2011. OUTCOME MEASURES Asthma exacerbation was defined as having a corticosteroid (CS) burst characterised by a prescription of high-dose oral CS for ≥3 days or one systemic CS injection, hospitalisation or emergency department visit. RESULTS Among severities, history of CS bursts was significantly associated with exacerbation. In mild and moderate asthma, exacerbation was significantly associated with age ≥45 years, being female, gastro-oesophageal reflux disease and chronic rhinitis. High medication possession ratio (MPR≥50%), compared with low MPR (<20%) showed adjusted ORs of 0.828 (95% CI 0.707 to 0.971) and 0.362 (0.185 to 0.708) in moderate and severe asthma, respectively. In severe asthma, compared with mild asthma, only allergic rhinitis and history of hospitalisation were strongly associated with exacerbation. When comparing frequent exacerbators to patients with single exacerbation, age ≥45 years, atopic dermatitis, anxiety and history of CS burst were significant risk factors in mild and moderate asthma, whereas no risk factors were significant in severe asthma. CONCLUSIONS Different associations between risk factors and asthma exacerbations based on asthma severity suggest that patients with mild asthma require greater attention to their age and comorbidities, whereas those with severe asthma require greater attention to hospitalisation history and drug adherence.

Abstract
ZnO and Ag-containing ZnO (ZnO/Ag) films with the Ag/Zn molar ratio of 3.3 and 9.1%, respectively were sol-gel coated on biomedical titanium for antibacterial and bioactive surface modification. X-ray diffraction analysis indicates that ZnO peaks increase with the calcination temperature of the samples. Scanning electron microscopy and energy dispersive of X-ray analyses reveal Ag-rich white particles (300~750 nm) on ZnO/Ag samples that were calcined at 400 °C. X-ray photoelectron spectroscopy analysis of ZnO/Ag samples shows that Zn and O exist as ZnO and Ag presents in metallic state. The coating samples exhibit similar UV light-induced hydrophilic conversion behavior. Potentiodynamic polarization test in a Ca-free Hank's balanced solution demonstrates better corrosion resistance of the coating samples compared with the polished sample. In the in vitro bioactivity test using the simulated body fluid, a layer of apatite is gradually deposited on the surface of sample ZnO/9Ag after 12 days of soaking. The MTT assay test shows that ZnO and ZnO/Ag films have weak compatibility with the L929 cells. The antibacterial test against E. Coli by the disk diffusion assay reveals that antibacterial activity of the coating samples increases with silver content of the films.

Abstract
In this study, inulin (INU) extracted from burdock root was utilized as a new film base material and combined with chitosan (CHI) to prepare composite films. Oregano and thyme essential oils (OT) were incorporated into the INU-CHI film to confer the films with bioactivities. The physical and optical properties as well as antioxidant and antimicrobial activities of the films were evaluated. INU film alone showed poor physical properties. In contrast, the compatibility of INU and CHI demonstrated by the changes in attenuated total reflectance-Fourier transformation infrared spectrum of the INU-CHI film increased tensile strength and elongation at break of the INU film by 8.2- and 3.9-fold, respectively. In addition, water vapor permeability, water solubility, and moisture content of the films decreased proportionally with increasing OT concentration in the INU-CHI film. Incorporation of OT also increased the opacity of a and b values and decreased the L value of the INU-CHI films. All INU-CHI films containing OT exhibited antioxidant and antimicrobial properties. Particularly, the INU-CHI film with 2.0% OT exhibited the highest 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), 2,2-diphenyl-1-picrylhydrazyl radical scavenging, and antimicrobial activities against four pathogens. Thus, the INU-CHI film containing OT developed in this study might be utilized as an active packaging material in the food industry.

Abstract
Objective To determine the dose of remifentanil needed to achieve successful insertion of the Streamlined Liner of the Pharyngeal Airway (SLIPA™) without the development of hypertension in 95% of the patients. Design Randomised controlled trial. Setting operating theatre of a university hospital Methods A total of 100 ASA I or II patients requiring SLIPA insertion were randomly assigned to receive normal saline (Group C) or one of the four different doses (0.5 µg/kg [Group R0.5], 1.0 µg/kg [Group R1], 1.5 µg/kg [Group R1.5] or 2.0 µg/kg [Group R2]) of remifentanil. Arterial blood pressure and heart rate were recorded at preanesthetic baseline, preinserton, and every one minute during the initial 3 minutes period after insertion. Results A Probit model of remifentanil concentration was predictive of successful insertion of SLIPA without the development of hypertension. The ED95 of remifentanil needed to suppress haemodynamic response from SLIPA insertion was 1.39 µg/kg (95% confidence interval, 1.06-2.61 µg/kg). Conclusions A single administration of remifentanil can effectively suppress haemodynamic changes due to the insertion of SLIPA.

Abstract
Introduction Streamlined Liner of the Pharynx Airway (SLIPA) is a disposable supraglottic airway. There are two strategies to select the size of SLIPA: by height and width of thyroid cartilage. This study compared the utility of the two strategies in selecting the optimal size. Methods One hundred forty-two patients were randomly divided into two groups with size selection by height (H) and the maximal width of the thyroid cartilage (T). The SLIPA size was selected by height in group H, and by the width of thyroid cartilage in group T. After inserting SLIPA, the investigator made note of the oropharyngeal leakage pressure (OLP) and the degree of insertion difficulty. We set the OLP as a primary outcome. In cases of an OLP <15 cmH2O, the investigator manipulated the apparatus to try to reposition it. If air still leaked, another attempt was made using a SLIPA one size larger until an OLP >15 cmH2O was achieved in up to three attempts. After insertion, the investigator measured the inspiratory and expiratory tidal volume. Post-operatively, the presence of blood or regurgitated fluid on the device was evaluated. Results OLP for group T was higher than that of group H (p=0.009). The need for manipulation and the leak fraction was higher in group H than in group T (p=0.008 and 0.034, respectively). The degree of insertion difficulty, number of trials and incidence of blood and regurgitated fluid on the device were similar between the two groups. Conclusions Both the width and height of thyroid cartilage can be used for selecting the optimal SLIPA size. (Hong Kong j.emerg.med. 2015;22:303-311)

Abstract
BACKGROUND AND OBJETIVE Older guidelines recommend that fractional exhaled nitric oxide (FeNO) should be checked more than twice during the same session to confirm an asthma diagnosis. Recent studies show the excellent reproducibility of FeNO measurements. Objetive: We aimed to determine whether repeated FeNO measurements during the same session are necessary for asthma screening. MATERIAL AND METHODS We retrospectively reviewed the electronic medical records of adult outpatients who visited the respiratory medicine department for diagnosis of asthma and assessed FeNO measurements obtained from June 2016 to July 2017. RESULTS Of the 132 patients enrolled, 79 (59.8%) were diagnosed with asthma. Repeated FeNO measurements taken during the same session showed high reproducibility (intraclass correlation coefficient >0.9; P<.001) and a strong correlation (Pearson coefficient >0.9; P<.001), although reproducibility and correlation were slightly weaker in patients with low FeNO values. The value of repeated measurement was not significant; however, the second FeNO measurement was significantly higher than the first measurement in patients with the worst and best lung function. The predictive power of the first measurement of FeNO (sensitivity, 80.5%; specificity, 85.1%) was not inferior to the second (sensitivity, 76.6%; specificity 85.1%). The same was true of the geometric mean of the two. CONCLUSIONS Repeated FeNO measurement during the same session is not essential for asthma screening in cases where the first acceptable FeNO measurement is performed using the proper method.

Abstract
Dissolved oxygen (DO) plays a crucial role in survival, growth, and normal physiological functions of aquatic organisms. Nevertheless, the mechanisms involved in hypoxic stress and adaptation have not been fully elucidated in Largemouth bass (Micropterus salmoides). To reveal the effect of acute hypoxia on Largemouth bass, we simulated acute hypoxia (DO: 1.2 ± 0.2 mg/L) in the laboratory and analyzed physiological parameters (RBCs, Hb, SOD, CAT, NA+/K+-ATPase, GPx, and MDA) and gene expression (HIF-1alpha and GLUT-1) in Largemouth bass exposed to various durations of acute hypoxia (0, 1, 2, 4, 8, 12, and 24 h). Our results indicated that acute hypoxic exposure significantly increased RBCs but decreased Hb. In addition, antioxidant enzyme activity was enhanced significantly in the liver and muscles at the initial stage of acute hypoxic exposure, but decreased significantly in gills during the entire process of hypoxic exposure. Furthermore, the expression levels of HIF-1alpha and GLUT-1 mRNA were significantly up-regulated in Largemouth bass under acute hypoxic exposure. In conclusion, our study provides a valuable basis for further elucidation of hypoxic adaptation and facilitates husbandry for an economically valuable species.

Abstract
This study compared the effect of dynamic hip screw (DHS) and proximal femoral nail anti-rotation (PFNA) in the treatment of intertrochanteric femoral fractures of elderly subjects and evaluated the effect of PFNA internal fixation. Two hundred and sixteen elderly patients with intertrochanteric femoral fracture who received treatment in Binzhou Medical University Hospital, Shandong, China were selected. They were divided into a PFNA group which adopted PFNA for internal fixation and a DHS group which adopted DHS for internal fixation, 108 cases in each group. The physical condition of the patients in the two groups were recorded on admittance. The fracture was typed according to Evans-Jensen classification criteria. Patients were followed up after surgery to evaluate the postoperative recovery and Harris score of hip joint function. Except for the length of hospital stay, the length of incision, interoperative blood loss, volume of drainage and duration of operation of the PFNA group were all superior to those of the DHS group (P less than 0.05); the incidence of postoperative complications of the PFNA group was lower than that of the DHS group (P less than 0.05); the early Harris score of the treatment was superior to that of the DHS group, and there was no remarkable difference (P>0.05). PFNA has more advantages than DHS in treating intertrochanteric femoral fracture of the elderly; hence it is worth wide application in clinical use.

Abstract
OBJECTIVE To investigate the optimal anticoagulation methods and monitoring strategy for Chinese patients undergoing heart valve replacement, which is potentially quite different from western populations. METHODS In this multicenter prospective cohort study, the anticoagulation and monitoring strategy data was acquired from 25 773 in-hospital patients in 35 medical centers and 20 519 patients in outpatient clinic in 11 medical centers from January 1st, 2011 to December 31th, 2015. RESULTS As for in-hospital patients, mean age of study population was (48.6±11.2) years old; main etiology of valve pathology was rheumatic (87.5%) origin among study cohort; 94.8% of study population received mechanical valve implantation; international normalized ratio (INR) monitoring (in all the study centers) and low-intensity anticoagulation strategy (31 hospitals chose target INR range of 1.5-2.5, and actual values of INR among 89.2% of 100 069 in-hospital monitoring samples were 1.5-2.5), with mean actual INR values of 1.84±0.53, and warfarin dosage of (2.82±0.93) mg/d were widely adopted among the study centers; strategies of in-hospital warfarin administration were similar in all the study centers; complication rates of low-intensity anticoagulation strategy were low in severe hemorrhage (0.02%), thrombosis (0.05%), and thromboembolism (0.05%) events, without anticoagulation-related death.As for 18 974 outpatient clinic patients, the follow-up rate was 92.47%, with a total of 30 012 patient-years (Pty). Anticoagulation-related morbidity and mortality rates were 0.67% and 0.15% Pty; major hemorrhage morbidity and mortality rates were 0.25% and 0.13% Pty; thromboembolism morbidity and mortality rates were 0.45% and 0.03% Pty.The mean dosage of warfarin daily dosage was (2.85±1.23) mg/d and INR value was 1.82±0.57.No significant regional difference in the intensity of anticoagulation therapy was noted during the study. CONCLUSIONS INR can be used as a normalized indicator for intensity of anticoagulation therapy in China.The optimal anticoagulation intensity with INR range from 1.5 to 2.5 is safe and effective for Chinese patients with heart valve replacement, and there is no significant regional difference in the intensity of anticoagulation therapy.

Abstract
Objective: To compare the diagnosis and treatment experience of brain abscesses and improve prognosis. Methods: The data of 302 patients of brain abscess at Department of Neurosurgery in Tianjin Medical University General Hospital from 1980 to 2014 was analyzed retrospectively. There were 215 male and 87 female patients aged from 11 to 82 years with mean age of (30±8) years. The patients was divided into 1980-2001 group and 2002-2014 group according to different diagnosis and the treatment methods. The therapy methods include operation and conservative treatment. There were 196 cases received operation, including 95 cases of excision, 89 cases of ventriculopuncture, 12 cases of excision after ventriculopuncture, 106 cases received drug conservative therapy. Two groups of information including clinical manifestation, abscess location, therapeutic effect and prognosis were compared by χ(2) test. Results: Compared to 1980-2001 group, adjacent infection incidence declined(χ(2)=8.000, P=0.005). The ratio of single abscess declined and multiple abscess increased(χ(2)=11.060, P=0.001), the infection proportion of frontal lobe and temporal lobe decreased(χ(2)=9.080, P=0.003; χ(2)=15.440, P=0.000). The ratio of headache and vomit and papilledema declined significantly(χ(2)=23.290, P=0.000; χ(2)=21.020, P=0.000; χ(2)=2.290, P=0.001). Total mortality of 302 patients were 23 cases and 5 cases of 1980-2001 group and 2002-2014 group (10.4% vs. 6.3%, χ(2)=1.180, P=0.277). However, there were statistical difference in postoperative mortality between both groups (14.4% vs. 4.0%, χ(2) =3.880, P=0.049). Conclusion: With the application of antibiotics and the development of neurosurgical techniques, the prognosis of brain abscess has been improved.

Abstract
Thermoset polyimides were prepared by thermally curing B-staged endcapped polyimide resins that were obtained by thermally baking PMR polyimide matrix resins. The polyimide matrix resins were prepared by incorporating flexible ether-bridged aromatic segments [–Ar–O–Ar–] into PMR polyimide backbone to improve their processability and impact toughness. Experimental results indicated that the B-staged polyimide resins possessed adjustable and easily controllable thermal processability which ensure that thermoset polyimides are produced with improved impact strength and high glass transition temperature compared with PMR-15. Thermal and thermo-oxidative stability as well as hygrothermal resistance of the thermoset polyimides were also systemically investigated.

Abstract
End-capped polyimide precursor solutions in ethyl alcohol were prepared by incorporating carbonyl groups into the polymer backbone of a second-generation PMR ( in situ polymerization of monomer reactants) polyimide, PMR-II-50, which exhibited good features as a matrix resin for carbon-fibrereinforced composites. Cured polyimides were prepared in an analogous process as the PMR-II polyimides. The thermal and thermo-oxidative stability of the cured polyimides was systemically investigated. It was found that the cured polyimide containing a 1:1 mole ratio of the carbonyl group [–C(O)–] to the hexafluoroisopropyl group [–C(CF3)2–] in the polymer backbone possessed a very high glass transition temperature (440 °C) and an excellent thermal decomposition temperature (576 °C). The onset temperature of the storage modulus curve was measured at about 400 °C with high retention ( >55%) of the storage modulus at 400 °C, compared to 10–15% of the corresponding PMR-II polyimide. Carbon-fibre-reinforced composites also showed a high onset temperature of the storage modulus (420 °C) and high storage modulus retention ( >85%) at 400 °C. Preliminary results indicated that the composite laminate exhibited excellent mechanical strength retention at 371 °C, which was superior to that of CF/PMR-II composites.

Abstract
High-temperature polyimide composites with low and stable dielectric properties were produced by thermally curing prepolyimide moulding compounds which were prepared by the wet impregnation of chopped short quartz fibres with a PMR-II polyimide matrix resin solution, followed by the evaporation of the solvent with vigorous stirring. The mechanical properties, thermo-oxidative stability as well as the dielectric and electric properties of the composites were studied. The experimental results showed that the composites exhibit outstanding mechanical properties and excellent thermal and thermo-oxidative stability at temperatures as high as 371 °C. It was revealed that both the dielectric constant (∼3.0) and loss tangent (∼10−3) of the composites were not obviously changed with a frequency in the broadband wavelength (1 kHz–20 GHz).

Abstract
We characterized 549 new human leukocyte antigen (HLA) class I and class II alleles found in newly registered stem cell donors as a result of high‐throughput HLA typing. New alleles include 101 HLA‐A, 132 HLA‐B, 105 HLA‐C, 2 HLA‐DRB1, 89 HLA‐DQB1 and 120 HLA‐DPB1 alleles. Mainly, new alleles comprised single nucleotide variations when compared with homologous sequences. We identified nonsynonymous nucleotide mutations in 70.7% of all new alleles, synonymous variations in 26.4% and nonsense substitutions in 2.9% (null alleles). Some new alleles (55, 10.0%) were found multiple times, HLA‐DPB1 alleles being the most frequent among these. Furthermore, as several new alleles were identified in individuals from ethnic minority groups, the relevance of recruiting donors belonging to such groups and the importance of ethnicity data collection in donor centers and registries is highlighted.

Abstract
Objective: To characterize the finals mispronunciation in Chinese-speaking children with functional articulation disorder (FAD), in order to promote the standardized diagnosis. Method: A retrospective study was conducted. From January to December 2013, 90 FAD children, diagnosed by Dysarthria Rating Scale and Mandarin Finals scale, were included in this study. Among them, 22 were found to have finals mispronunciation; the average age was (6.56±0.26) years. According to the finals classification, six different finals (simple finals, front vowel compound finals, central vowel compound finals, back vowel compound finals, anterior nasal finals, and posterior nasal finals) were defined; the produced sound samples of those subjects were analyzed. Result: In all these children, 22 of 90 (24%) were found having finals mispronunciation, the occurring rates of which with omission and substitution errors were: 3% (4/132) for simple finals, 30% (26/88) for front vowel compound finals, 26% (23/88) for central vowel compound finals, 7% (8/110) for back vowel compound finals, 73%(128/176) for anterior nasal finals and 73% (112/154) for posterior nasal finals, respectively. In omission and substitution errors, the ratios of the finals above were 50% (150/301), 3% (10/301), 5% (14/301), 36% (107/301), 2% (5/301) and 5% (15/301), respectively. The most frequently occurred mispronunciation were omission, substitution and distortion, with rates of 37% (273/748), 4% (28/748) and 8% (61/748), respectively. Conclusion: The FAD children have remarkable mispronunciation of finals. Omission is the main error. The nasal finals are the most commonly involved, followed by front vowel and central vowel compound finals. The simple finals and the back vowel compound finals are most commonly produced in omission and substitution. These finals production features should be considered when making and implementing rehabilitation programs.

Abstract
Ammopiptanthus mongolicus, an evergreen broadleaf legume shrub, can survive under conditions of high and low temperature, extreme salinity, and drought. This attribute makes it an ideal model for studying mechanisms of stress tolerance in plants. However, simple sequence repeat (SSR) resources for this species are insufficient in public databases. In this study, a total of 44,959 unigenes identified from the A. mongolicus transcriptome were used for SSR analysis by MIcroSAtellite (MISA). A total of 13,859 SSRs were found to be distributed within 10,409 unigenes, with an average length of 15 bp and an average density of one SSR per 4.4 kb. There were 222 different motif types in the A. mongolicus transcriptome, and mononucleotide repeats represented the main type, accounting for 44.2% of all SSRs. The (A/T)n repeat was the most frequent motif, accounting for 42.37% of all SSRs. We also performed Gene Ontology functional analysis, Kyoto Encyclopedia of Genes and Genomes database pathway analysis, and eggNOG analysis, and identified 6157, 2301, and 9845 unigenes containing SSRs in these three databases, respectively. The functional categorization of A. mongolicus unigenes containing SSRs revealed that these unigenes represent many transcribed genes with different functions. These data provide sequence information that may be used to improve molecular-assisted markers for the study A. mongolicus genetic diversity.

Abstract
OBJECTIVE Pharmacotherapy of depression in children and adolescents is complex. In the absence of research into the efficacy and safety of antidepressants in this group of patients, their off-label prescription is common. This paper aimed to illustrate the prescription pattern of antidepressants in children and adolescents from major psychiatric centres in Asia. METHODS The Research on Asia Psychotropic Prescription Pattern on Antidepressants worked collaboratively in 2013 to study the prescription pattern of antidepressants in Asia using a unified research protocol and questionnaire. Forty psychiatric centres from 10 Asian countries / regions participated and 2321 antidepressant prescriptions were analysed. RESULTS A total of 4.7% antidepressant prescriptions were for children and adolescents. Fluoxetine, sertraline, and escitalopram were the most common antidepressants prescribed for children and adolescents. Almost one-third (30.3%) of prescriptions were for diagnoses other than depressive and anxiety disorders. There was less antidepressant polypharmacy and concomitant use of benzodiazepine, but more concomitant use of antipsychotics in children and adolescents compared with adults. CONCLUSION Off-label use of antidepressants in children and adolescents was reported by 40 Asian psychiatric institutions that participated in the study. In-service education and regulatory mechanisms should be reinforced to ensure efficacy and safety of antidepressants in children and adolescents.
