Abstract
Objective: To explore the surgical strategy for Ebstein anomaly in children. Methods: From January 2003 to December 2015, a total of 141 cases of Ebstein anomaly were treated at Department of Pediatric Cardiothoracic Surgery, Shanghai Children's Medical Center, School of Medicine, Shanghai Jiaotong University. There were 65 male and 76 female patients, with age of (6.9±1.6) years (ranging from 10 months to 15 years), weight of (19.6±4.7) kg (ranging from 6.5 to 59.0 kg). All patients were diagnosed by 2 dimensional Doppler echocardiography and the septal leaflet and posterior leaflet displaced downward from 1.0 to 5.0 cm. The tricuspid valve regurgitation (TR) were mild in 26 cases, moderate in 46 cases and severe in 69 cases. Tricuspid valvuloplasty were performed in 131 cases (94 cone reconstruction, 37 valve hoist), tricuspid valve replacement in 2 cases and tricuspid valve closed in 8 cases. Surgical strategy were divided into biventricular heart function in 77 cases, one and a half ventricular heart function in 56 cases, and single ventricular heart function in 8 cases. Results: Three patients were changed to one and a half ventricular repair from biventricular repair due to unstable hemodynamics in the early postoperative period. One case died in biventricular group. The complete atrioventricular block were occurred in 3 patients and pacemaker were applied. One hundred and forty cases discharged from hospital. There were mild TR in 118 cases, moderate in 14 cases and closed in 8 cases. One hundred and thirty-seven cases were followed up regularly in 18 to 172 months. Ninety-one cases were treated by cone reconstruction (mild TR in 75 cases, moderate in 15 cases and severe in 1 case). Thirty-six cases were operated by tricuspid valve hoist (mild TR in 21 cases, moderate in 12 cases and severe in 3 cases). In the patients with severe TR (4 cases), 3 cases were reoperated by cone reconstruction. One case's valve was closed because of the dysplasia of the anterior valve and then from one and a half ventricular heart function to single ventricular function, the oxygen saturation was increased. Two patients underwent tricuspid valve replacement, 1 died and the other's mechanical valve was removed, and changed to single ventricular function repair. Conclusions: Although tricuspid cone reconstruction can achieve good results, the stable hemodynamic of early postoperative can be effectively maintained by using the surgical strategy of one and a half ventricular repair. To the patients with severe tricuspid regurgitation and hypoxemia due to severe tricuspid valve dysplasia, transforming to a functional single ventricle may be the only choice when there comes to the unstable hemodynamic.

Abstract
Objective: To compare the outcome of postoperative adjuvant chemotherapy and surgery alone for stage pT1b-3N0M0 squamous cell carcinoma (SCC) of the thoracic esophagus. Methods: Two hundred and thirty-eight patients who underwent esophagectomy for stage pT1b-3N0M0 SCC of the thoracic esophagus in Department of Thoracic Surgery, Fourth Hospital, Hebei Medical University between January 2008 and February 2011 were analyzed retrospectively. These included postoperative adjuvant chemotherapy for 118 patients and surgery alone for 120 patients. In postoperative adjuvant chemotherapy arm, 3 or 4 cycles of taxol+ cisplatin (TP, n=33) or fluorouracil+ cisplatin (FP, n=85) regimens were given commencing from 4 to 6 weeks after surgery. Survival analysis was performed using Kaplan-Meier method. Univariate analysis for prognostic factors was performed by Log-rank test and multivariate by Cox regression model. Results: The 3- and 5-year disease-free survival (DFS) rates were 57.9% and 53.8%, respectively for postoperative adjuvant chemotherapy patients, compared to 40.4% and 32.5% for patients who underwent surgery alone (χ2=11.973, P=0.001). The 3- and 5-year overall survival (OS) rates were 64.4% and 55.9% in postoperative adjuvant chemotherapy patients, and 46.7% and 33.5% in surgery alone patients (χ2=13.110, P=0.000). Stratification analysis showed that there was significant difference in stage T3 patients (χ2=7.895, P=0.006), but not in stage T1b (χ2=0.762, P=0.383) and T2 (χ2=1.259, P=0.262) patients between adjuvant chemotherapy and surgery alone. Both DFS rate (χ2=1.748, P=0.186) and OS rate (χ2=2.200, P=0.138) of TP group were similar with FP group. Conclusion: In lymph node negative esophageal SCC patients, postoperative adjuvant chemotherapy shows survival benefits in stage T3 patients.

Safety and efficacy of sofosbuvir-based treatment of acute hepatitis C in end-stage renal disease patients undergoing haemodialysis. Aliment Pharmacol Ther 2018; 47:526-532. [PMID: 29250808 DOI: 10.1111/apt.14429] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2017] [Revised: 07/24/2017] [Accepted: 10/31/2017] [Indexed: 12/27/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) infection in patients undergoing haemodialysis is prevalent and aggressive. The treatment of chronic hepatitis C has been revolutionised by the advent of direct-acting antivirals (DAAs). However, the safety, efficacy, and tolerance of DAAs in the treatment of acute HCV infection in patients with end-stage renal disease who are on haemodialysis are unknown. AIM To evaluate the safety and efficacy of sofosbuvir plus daclatasvir in this specific, difficult-to-treat population. METHODS We conducted a prospective and observational study of end-stage renal disease patients who were undergoing haemodialysis and were acutely infected with HCV. Patients received a half dose of sofosbuvir (200 mg) and a full dose of daclatasvir (60 mg) daily. The primary endpoint was the proportion of patients with sustained virological responses (SVRs); the other primary outcomes were safety and tolerability. RESULTS Thirty-three patients were enrolled in the study. The median HCV RNA viral load at baseline was 6.8 log10 IU/mL. Twenty-four patients were infected with HCV genotype 2a, seven patients with 1b, and two patients with 2a+1b. All patients achieved a SVR at 12 weeks after the end of treatment. The treatment was well tolerated, and there were no drug-related serious adverse events. CONCLUSION A half dose of sofosbuvir (200 mg once daily) plus a full dose of daclatasvir (60 mg once daily) were suitable for the treatment of acute HCV-infected patients who were undergoing end-stage renal disease and were on haemodialysis.

Abstract
BACKGROUND MUC16 is a tumor-specific antigen overexpressed in ovarian (OC) and pancreatic (PC) cancers. The antibody-drug conjugate (ADC), DMUC5754A, contains the humanized anti-MUC16 monoclonal antibody conjugated to the microtubule-disrupting agent, monomethyl auristatin E (MMAE). PATIENTS AND METHODS This phase I study evaluated safety, pharmacokinetics (PK), and pharmacodynamics of DMUC5754A given every 3 weeks (Q3W, 0.3-3.2 mg/kg) or weekly (Q1W, 0.8-1.6 mg/kg) to patients with advanced recurrent platinum-resistant OC or unresectable PC. Biomarker studies were also undertaken. RESULTS Patients (66 OC, 11 PC) were treated with DMUC5754A (54 Q3W, 23 Q1W). Common related adverse events (AEs) in >20% of patients (all grades) over all dose levels were fatigue, peripheral neuropathy, nausea, decreased appetite, vomiting, diarrhea, alopecia, and pyrexia in Q3W patents, and nausea, vomiting, anemia, fatigue, neutropenia, alopecia, decreased appetite, diarrhea, and hypomagnesemia in Q1W patients. Grade ≥3-related AE in ≥5% of patients included neutropenia (9%) and fatigue (7%) in Q3W patients, and neutropenia (17%), diarrhea (9%), and hyponatremia (9%) in Q1W patients. Plasma antibody-conjugated MMAE (acMMAE) and serum total antibody exhibited non-linear PK across tested doses. Minimal accumulation of acMMAE, total antibody, or unconjugated MMAE was observed. Confirmed responses (1 CR, 6 PRs) occurred in OC patients whose tumors were MUC16-positive by IHC (2+ or 3+). Two OC patients had unconfirmed PRs; six OC patients had stable disease lasting >6 months. For CA125, a cut-off of ≥70% reduction was more suitable for monitoring treatment response due to the binding and clearance of serum CA125 by MUC16 ADC. We identified circulating HE4 as a potential novel surrogate biomarker for monitoring treatment response of MUC16 ADC and other anti-MUC16 therapies in OC. CONCLUSIONS DMUC5754A has an acceptable safety profile and evidence of anti-tumor activity in patients with MUC16-expressing tumors. Objective responses were only observed in MUC16-high patients, although prospective validation is required. CLINICAL TRIAL NUMBER NCT01335958.

Abstract
OBJECTIVE To study the spatial expression of trophectoderm cells in human embryonic preantral blastocysts. METHODS The study used Gardner score 5AA blastocysts harvested on day 6 after fertilization from assisted reproductive technology. Microcapsules were used to separate trophectoderm cells from the epidermal cells. Single-cell sequencing was performed. P<0.05 was calculated by unpaired t test, and the difference was 2 times. Here we determined, for the first time, global gene expression patterns in the polar/mural trophectoderm isolated from human blastocysts. Unsupervised hierarchical clustering analysis and gene ontology (GO) functional classification were performed using bioinformatics software. Differentially expressed genes were annotated by the Database for Annotation, Visualization and Integrated Discovery. Functions of differentially expressed genes were further annotated using encyclopedia of genes and genomes. RESULTS The results showed that there were up to 306 genes in the trophoblast cells and up to 75 genes in the trophoblast cells. Unsupervised cluster analysis of polar trophoblast cells and mural trophoblast cells were divided into two groups, belonging to different types and biological functions. Differences in gene function indicated that the biological functions of GO gene uptake genes were mainly transcription, energy metabolism, protein synthesis, transport, oxidative stress, ion transport, protein synthesis and transport, cell cycle regulation, actin growth, etc. They were mainly involved in ubiquitin-mediated protein hydrolysis, oxidative phosphorylation, Wnt signaling pathway, estrogen androgen metabolism and other signal pathways; wall trophoblast cells up-regulated gene GO biological function, which was mainly proteolytic metabolism, cell cycle arrest, apoptosis, activation of MAPK, carbohydrate transport, synaptic regulation, cell growth, calcium channel activation, positive B cell differentiation, T cell apoptosis and other biological functions, which were mainly involved in B cell receptor, T cell receptor, white blood cells cross-endothelial transplantation, VEGF expression, gap connection, GnRH secretion, apoptosis and other signaling pathways. CONCLUSION The gene expression of blastocysts trophectoderm is revealed from the spatial dimension, indicating that differentiation of polar and mural trophectoderm of blastocysts is accompanied by differences between the two cell lineages, and the polar and mural trophectoderms are coordinated with each other and the blastocyst hatching and embryo implantation processes are finely adjusted. Further data analysis is expected to find the endogenous molecular specificity of the regulation of embryo implantation.

Abstract
As an important part of paediatric science, paediatric diagnosis was in the initial stage of its development before the Song Dynasty. The main measures of diagnosing diseases were observation and pulse palpation, especially the latter. The rapid development of paediatrics in the Song Dynasty necessitated thepaediatric diagnosis to develop further, emphasizing the spiritual expressions of the eyes and fingerprint, with its special features gradually developed in the period of the Jin and Yuan Dynasties.During this period, the paediatrics diagnosis was developed on the basis of the previous generations, with equal importance paid to both observation and pulse feeling. In the period of the Ming and Qing Dynasties the four paediatric diagnostics were constantly enriched with attentions paid to the use of multiple approaches and thus the diagnostics was perfected day by day.

Abstract
OBJECTIVE To explore the function of tumor derived IgG (tIgG) and whether the tIgG can inhibit T cells activity. METHODS The tIgG was purified from ovarian cancer tissue. The cord blood monocyte cells (CBMC) and cord blood lymphocyte (CBL) were isolate from human umbilical cord blood. The CBMC and CBL were stimulated with phytohaemagg lutinin (PHA) in order to let the CBMC and CBL in the state of proliferation. Carboxyfluorescein succinimidyl amino ester (CFSE) was cultured with CBMC and CBL. CFSE had no cell toxicity, which could penetrate through the cell membrane and combine the intracellular protein. The fluorescence intensity decreased with the proliferation of cells step by step, so the proliferation of these cells could be detected in flow ctytometry. The tIgG which was purified from ovarian cancer tissue was divided into three groups, 1 mg/L group, 10 mg/L group, and 100 mg/L group, and the intravenous immunoglobulin (IVIG) was also divided into three groups too. The CBMC and CBL were treated by tIgG with 1 mg/L, 10 mg/L, and 100 mg/L in order to observe the proliferation of T cells. The cells were treated with IVIG as a positive control group, and the cells were treated with phosphate buffer saline (PBS) as a negative control. The proliferation of CD4+ or CD8+ T cells were detected in CBMC and CBL. The proliferation of the T cells in CBMC and CBL after 64 h and 86 h were detected. RESULTS In the system of CBMC, the tIgG could suppress the proliferation of CD4+ or CD8+ T cells. The results could also be found in the system of CBL. The CD4+ or CD8+ T cells in the group which were treated with PBS were more active than those in the group which were treated with tIgG and IVIG. The suppression in the group which were treated with tIgG, was stronger than that in the group treated with IVIG. In addition, the suppression of T cells in the group which were stimulated with tIgG as 100 mg/L was more effective than that in the group which were stimulated with tIgG as 10 mg/L. This could prove that tIgG had the function of immunomodulation. CONCLUSION The tIgG can be involved in immune escape of cancer.

Abstract
Liver transplantation is the most effective salvage treatment for advanced liver failure, but its clinical application is limited by a shortage of liver donor, strict technology admittance, and complex and diverse issues in liver damage control before transplantation. We need to better understand the indications for liver transplantation in liver failure patients, select surgical timing correctly, and develop proper surgical regimens, in order to improve the rescue and cure rate of such patients. In addition, great achievements have been made in living-donor liver transplantation, auxiliary liver transplantation, and ABO-incompatible liver transplantation, which should be taken seriously in clinical practice.

Abstract
Objective: To evaluate the feasibility of modified test system for sound localization (SL) in children. Methods: Modified system (6 male, 9 female) and traditional method ( 5 male, 5 female) were used for evaluation of minimum audible angle(MAA) and root-mean-square error(RMS) error of 4 to 6 years old children, and the results were compared to verify the accuracy and effectiveness of the modified test system for children sound localization.SPSS 17.0 software was used to analyze the data(t test). Results: (1) Comparison of veracity of modified system and traditional test: when tested at the positive front position using modified system, MAA and RMS error were(3.23±1.00)° and (13.68±5.18)° respectively.When using traditional method, MAA and RMS error were(3.17±0.59)°and (13.96±4.56)° respectively. No statistical differences were found between two groups(t value was 0.16, -0.14, both P>0.05). (2) Comparison of time used were as followed: when using modified system, it was (14.67±1.95) min for MAA, and (6.67±1.35) min for RMS error. When using traditional method, it was (36.30±6.81) min for MAA, and (21.00±3.50) min for RMS error. Time used were significant shorter in modified system than in traditional method (t value was-9.78, -12.37, both P<0.05). Conclusion: Modified test system for children sound localization is useful and reliable in children's horizontal SL test.The time used of modified test system is shorter than that of traditional test system.

Abstract
Head and neck cancer is one of the most prevalent cancers around the world. Head and neck squamous cell carcinoma (HNSCC) accounts for nearly 90% of head and neck cancer. In recent years, significant advances have been made in immunotherapy for HNSCC. Although some clinical trials targeting immune checkpoints have shown success, the molecular mechanism for regulation of programmed death 1 (PD-1) and its ligand (PD-L1) is partially understood. In an effort to explore the effect of activation of signal transducers and activators of transcriptions (STAT3) on PD-1/PD-L1, the expression and correlation between phosphorylation of STAT3 and PD-1/PD-L1 were determined with immunostaining of human and mouse HNSCC tissue sections. PD-1/PD-L1 overexpression was found to be significantly associated with p-STAT3 in human and mouse HNSCC. Targeting STAT3 by a small molecule effectively inhibited the expression of PD-L1 in the CAL27 cell line. Furthermore, we found that blockade of STAT3 signaling downregulated PD-1/PD-L1 in a Tgfbr1/Pten 2cKO HNSCC mouse model. These findings suggest that STAT3 signaling plays an important role in PD-1/PD-L1 regulation and the antitumor immune response of HNSCC.

Abstract
The aim of this review was to examine the current literature regarding application of cochlear implantation on patients with unilateral sensorineural hearing loss (USNHL) for improvement on sound localization. The literature were searched in the PubMed database with 'cochlear implantation AND single-sided deafness' or 'cochlear implantation AND unilateral deafness' as keywords. The publication date of the articles was up to 2015-2-12. A total of 12 articles were included. The results show that the ability of sound localization for most of the USNHL subjects (90%) with cochlear implantation was significantly improved than that without CI, which suggests that CI is a superior auditory rehabilitation treatment than BAHA and CROS hearing aids for patients with USNHL, because of the re-establishment of the benefits of binaural hearing. In addition, the benefit of CI for USNHL requires a period of auditory experience or training. About 30% subjects showed significantly improvement on sound localization ability after CI worked for three months. For most of the patients (90%), the sound localization ability improved after CI worked for six months. When CI worked for nine months, all the subjects would show improvement on sound localization ability. Sound localization of the USNHL subjects with a CI is based primarily on interaural level differences (ILD) while interaural time differences (ITD) provide little advantage or probably not perceptible at all. The younger subject suffers from USNHL, the stronger the plasticity of the auditory center shows, which results in more obvious degeneration of the affected side and adaptive enhancement of the contralateral side of the auditory pathway. Similarly, the longer duration of USNHL lead to more obvious degeneration of the affected side and adaptive enhancement of the contralateral side. An adaptive enhancement of auditory pathway corresponding to the healthy ear will rely more on the monaural spatial cues that available to the intact ear to improve the sound localization in the horizontal plane. Contrarily, the degeneration of auditory pathway corresponding to the USNHL may be limited to re-reorganize from auditory deprivation even after CI, which may increase the risk that a few subjects cannot re-establish the binaural benefits after CI. Therefore, patients with USNHL should accept CI as soon as possible to obtain good binaural benefits, especially for sound localization.

Abstract
OBJECTIVE To understand the HIV infection status in middle aged and old men and the association between HIV infection and female sex workers in a city in Hubei province and provide evidence for the targeted prevention and control of HIV infection. METHODS Ten communities/villages were selected through stratified cluster sampling from the suburban and rural areas of the city. A total of 634 men aged ≥50 years were surveyed by using self-designed questionnaire in December, 2014. RESULTS The awareness rate of HIV/AIDS related knowledge was 13.3%(68/513). Among the men surveyed, 63.2%(371/587)thought they couldn't be infected with HIV, 9.1%(52/573)believed that extramarital sex is acceptable, and 32.4%(189/583)considered that commercial sexual behavior is just as well. Among the surveyed men reporting sexual behavior in the past 6 months, 6.6%(15/228)had sex with regular sexual partners, in which 63.6%(7/11)never used condoms, 21.8%(128/586)reported that some friends had commercial sexual behaviors. Among 601 men receiving HIV testing, 7 were HIV positive(1.2%). The HIV detection rates among the men living at 3 communities near red light district were 4.2%(5/119), 1.1%(1/95)and 0.5%(1/192)respectively; while no HIV infections were found in the men living at 2 towns far away from red light district. Seventy seven of 581 men surveyed(13.2%)reported to meet visiting female sex workers and they had higher HIV positive rate(5.2%, 4/77)than those without such experiences(0.6%, 3/504)(P=0.007). CONCLUSION The middle aged and old men in this city had low awareness of HIV/AIDs related knowledge, and high-risk sexual behaviors existed among them. HIV positive rate was relatively high in this population, and HIV infection might be associated with sex service.

Abstract
OBJECTIVE To investigate the characteristics of hepatitis B virus (HBV) transmission among family members in families with familial clustering of HBV infection and poor outcomes, as well as the prevalence and distribution characteristics of HBsAg in offspring with different parental HBsAg status. METHODS The general information of each member in families with poor outcomes were collected from 2007 to 2010, and serological test was performed to analyze the prevalence and distribution of HBsAg in family members. The chi-square test or Fisher's exact test was used to analyze and compare the sex of offspring and the prevalence of HBsAg in them in 266 nuclear families with different paternal and maternal HBsAg status. RESULTS The positive rates of HBsAg in parents, siblings, children, and spouses of the probands were 20%, 88.2%, 76.8%, and 9.5%, respectively. The nuclear families with HBsAg-positive fathers and HBsAg-negative mothers had a significantly increased proportion of male offspring (male/female ratio = 2.02) compared with those with HBsAg-positive mothers and HBsAg-negative fathers (1.22) or those with HBsAg-negative fathers and mothers (0.96). In addition, in the nuclear families with HBsAg-positive fathers and HBsAg-negative mothers, the male offspring had a significantly higher HBsAg positive rate than female offspring (37.4% vs 13.8%), while in those with HBsAg-positive mothers and HBsAg-negative fathers or those with HBsAg-negative fathers and mothers, HBsAg positive rate showed no significant difference between male and female offspring. CONCLUSION In families with familial clustering of HBV infection and poor outcomes, mother-to-child transmission is still the major route of HBV transmission, but father-to-child transmission also plays a role in HBV transmission in this special population. Positive HBsAg in fathers is associated with the increased proportion of male offspring, and father-to-son transmission of HBV is higher than father-to-daughter transmission.

Abstract
Objective:To discuss the clinical significance of the pneumatization of the maxillary sinus by sinus CT.Method:One hundred patients encountered in our hospital during March 2012 and December 2012 were included in this study.The pneumatization of the anterior part of the maxillary sinus were observed.Result:①The pneumatization of prelacrimal recess was divided into 3 types. TypeⅠ: The pneumatization of maxillary sinus frontal process did not reach into the front of the nasolacrimal duct(42% of the left, 42% of the right); Type Ⅱ: The pneumatization of maxillary sinus frontal process extended into the front of the nasolacrimal duct,but not exceeding ½of the nasolacrimal duct circumference(39% of the left,37% of the right); Type Ⅲ: The pneumatization of maxillary sinus frontal process extended into the front of the nasolacrimal duct more than ½ of the circumference(19% of the left, 21% of the right).②The pneumatization of maxillary sinus palatal process was divided into 3 types. TypeⅠ: maxillary sinus palatal process non gasified (49% of the left, 53% of the right); Type Ⅱ: palatal process gasification into the nasal floor, but not more than ½of the width of nasal floor(45% of the left and 43% of the right);Type Ⅲ: palatal process gasification into the nasal floor more than ½ of the width of nasal floor(6% of the left, 4% of the right).③The pneumatization of maxillary sinus extended into alveolar process was divided into 3 types.Type Ⅰ: the bottom of the maxillary sinus is higher than the oral surface of hard palate(49% of the left and 51% of the right); Type Ⅱ: the bottom of the maxillary sinus is lower than the oral surface of hard palate and non tooth root protruding into the maxillary sinus(44% of the left and 39% of the right); Type Ⅲ: the tooth root process was protruded into maxillary sinus(7% of the left and 11% of the right).④The pneumatization of maxillary sinus extended into the zygomatic process was divided into 3 types. Type Ⅰ: the gasification of the zygomatic process is not more than the orbital lateral wall(80% of the left, 82% of the right); Type Ⅱ: the gasification of the zygomatic process is more than the orbital lateral wall, (20% of the left, right 18% of the right);Type Ⅲ: the gasification of the zygomatic process is also more than the inferior orbital wall, this paper is not observed Ⅲ type pneumatization.⑤The pneumatization of of the anterior wall of the maxillary sinus was divided into 3 types. Type Ⅰ: infraorbital nerve tube completely in the bone wall of the maxillary sinus(51% of the left, 57% of the right); Type Ⅱ: the half of the infraorbital neural tube was inburst into the maxillary sinus(39% of the left and 31% of the right); Type Ⅲ: infraorbital neural tube was totally protruding into to the cavity of the maxillary sinus(10% of the left and 12% of the right). Conclusion:The pneumatization of the anterior part of the maxillary sinus varies considerably and requires attention during ESS. The pneumatization degree of maxillary sinus should be confirmed accurately in preparation. It is foundamental for selecting the suitable surgical approach for Nasal endoscopic maxillary sinus surgery. It is also important for completely removed the maxillary lesions in operation.

Abstract
Objective:To cross-culturally translate the questionnaire of olfactory disorders(QOD)into a simplified Chinese version, and evaluate its reliability and validity in clinical.Method:A simplified Chinese version of the QOD was evaluated in test-retest reliability, split-half reliability and internal consistency.Then it was evaluated in validity test including content validity, criterion-related validity, responsibility. Criterion-related validity was using the medical outcome study's 36-item short rorm health survey(SF-36) and the World Health Organization quality of life-brief (WHOQOL-BREF) for comparison. Result: A total of 239 patients with olfactory dysfunction were enrolled and tested, in which 195 patients completed all three surveys(QOD, SF-36, WHOQOL-BREF). The test-retest reliabilities of the QOD-parosmia statements(QOD-P), QOD-quality of life(QOD-QoL), and the QOD-visual simulation(QOD-VAS)sections were 0.799(P<0.01),0.781(P<0.01),0.488(P<0.01), respectively, and the Cronbach' s α coefficients reliability were 0.477,0.812,0.889,respectively.The split-half reliability of QOD-QoL was 0.89. There was no correlation between the QOD-P section and the SF-36, but there were statistically significant correlations between the QOD-QoL and QOD-VAS sections with the SF-36. There was no correlation between the QOD-P section and the WHOQOL-BREF, but there were statistically significant correlations between the QOD-QoL and QOD-VAS sections with the SF-36 in most sections.Conclusion:The simplified Chinese version of the QOD was testified to be a reliable and valid questionnaire for evaluating patients with olfactory dysfunction living in mainland of China.The QOD-P section needs further modifications to properly adapt patients with Chinese cultural and knowledge background.

Abstract
OBJECTIVE The aim of this study was to compare the sex difference of the speech-ABR in young adults and school age children. METHODS Speech-ABR of eighty normal hearing subjects including twenty four school-age children(12 girls and boys, age from 6 to 12 years old) and fifty six young adults(male 29, female 27, age from 20 to 34 years old) were recorded. The speech syllable /da/ as stimulus sound was transmitted to right ear by insert earphones in speech-ABR test. RESULTS ① Females had a shorter latency than males in transient response (waves V, A and O) and sustained response (waves D, E and F) of speech-ABR (P<0.05, respectively). The amplitudes of transient response (waves V and A) and sustained response (waves D, E and F) in females were also significantly larger than those in males (P<0.05, respectively), except for amplitude of peak O (P>0.05). The V/A slope in females was significantly steeper than that in males[(-0.43±0.13)vs(-0.25±0.08), P<0.01]. ②The amplitude and latency of speech-ABR in transient response (waves V, A and O) and sustained response (waves D, E and F) were not significantly different between boys and girls. Only the V/A slope in girls was significantly steeper than that in boys [(-0.46±0.12)vs(-0.35±0.15), P<0.05]. ③The latency of speech-ABR was significantly prolonged in young men when compared with boys in both transient response (waves V, A and O) (P<0.05, respectively) and sustained response (waves D and F, P<0.05, respectively), except for wave E (P>0.05). The amplitude of speech-ABR showed a statistically significant decrease (P<0.05, respectively) only in wave A, D and F. Contrarily, the decrease in response amplitudes of waves V, E and O were not statistically significant (P>0.05, respectively). The V/A slope was steeper in boys than in young men, which was statistically significant (P<0.05). ④ In girls and young women, peak latency and magnitude of speech-ABR showed similar characteristics. No significant differences were found in either transient response or sustained response. The V/A slope between girls and young women was similar without significant difference (P>0.05). CONCLUSIONS The female adults have shorter wave latency and larger amplitude of speech-ABR than males, which suggests that females have better speech encoding in brainstem. There are few differences between female and girls in wave latency and amplitude. The speech encoding in brainstem in young men tends to become worse than in boys. It implies that the increase of androgen might weaken the ability of the speech encoding in brainstem.

Abstract
OBJECTIVE To observe image features of sinus of Valsalva aneurysm (SVA) extending into left ventricle by echocardiography. METHODS Echocardiographic features of 5 cases of SVA extending into left ventricle and underwent surgery at Union Hospital from July 1995 to September 2015 were reviewed retrospectively and image and surgical findings were compared. A total of 4 patients were diagnosed by conventional and 3D echocardiography before surgery, and 1 patient was diagnosed by conventional echocardiography. RESULTS The origin, extending position, rupture status, complications of the SVA and associated cardiovascular lesions determined by echocardiography were entirely consistent with surgical findings in all cases, with the exception of one failed diagnosis of hypoplasty of an adjacent aortic cusp. Besides the common features of SVA, echocardiographic features of SVA extending into left ventricle included a thin-walled saccular lesion arising from the aortic root in continuation with the aortic annulus, with significant morphological changes and movement. Moreover, following features were observed: very low origin of the saccular lesion arising between the sinus base and the aortic annulus; the aneurysm going back and forth between the aortic root and the left ventricular outflow tract in 4 cases with an intact interventricular septum, and between the left ventricle and the right ventricle through the septal defect in another case complicated by a huge ventricular septal defect; diastolic shunt into the left ventricle when ruptured; displacement of the adjacent aortic annulus due to compression of aneurismal origin and prolapse of both aortic valve and annulus observed in all cases, resulting in a severe aortic regurgitation; obstructions of the left ventricular outflow tract due to the space-occupying effect were also found in 2 cases. CONCLUSION The SVA extending into left ventricle has distinguished echocardiographic characteristics, which could be accurately diagnosed either by conventional or real-time 3D echocardiography.
