Objective To analyse the mental health of adolescents with cochlear implants and provide the ref‐erence for programming the personalize rehabilitation schedule of audio - speech -psychological .Methods The mental health test(MHT) was used to evaluate the mental health status of 60 adolescent with cochlear implants ,and compared with those of adolescent with normal hearing .Results The incidence of psychological problems was 3 .33% in adolescent with cochlear implants .The hypersusceptilility scores of the group of cochlear implants (5 .63 ± 2 .22) was higher than that of in normal hearing group(4 .05) in ,which was significantly different(P<0 .01) . The body syndrome scores in the cochlear implants group (4 .03 ± 2 .72) was lower than that of in normal hearing group(4 .99) ,which was significantly different(P<0 .01) .The phobic tendency scores in cochlear implants group (1 .95 ± 2 .01)was significantly lower than that of in normal hearing group (3 .06)(P<0 .01) .Conclusion The over‐all mental health of adolescent with cochlear implants is good .Cochlear implants can help them improve hearing and speech function ,and improve quality of life ,but they still need parents ,teachers and the community to pay more at‐tention and care to help them get through adolescence ,and return to mainstream society .

Objective To investigate the clinical value of serum lipoprotein ( a ) concentration in evaluation of plaques characteristics for patients with coronary atherosclerotic heart diseases ( CAHD ) . Methods Using case-control method, Patients with suspicious CAHD, received coronary computed tomography angiography in the Shanghai East Hospital during October 2013 to June 2015 were enrolled.According to the results of coronary artery CTA, the patients were divided into two groups : the CAHD group (352 cases) and control group(438 cases) , the particle concentrations and mass concentration of lipoprotein(a), triglyceride, total cholesterol, HDL-C, LDL-C, glucose, HBA1c and hs-CRP and other tests were measured, the patients of CAHD group were divided into three subgroups by characteristics of coronary artery plaques including soft plaque (176 cases), calcified plaque (90 cases) and mixed plaque (86 cases), analysis were made with all these data.Using T test or variance analysis to compare the means between or among groups, the risk for CAHD was analyzed by logistic regression, the relationship between LP (a) -P and LP( a) -M were explored by linearly egression analysis, Conformance test were analyzed using kappa test.Results Compared with control group, the mean results of the CAHD group are significantly higher than that of control group, including LP (a) -P 18.5(8.3 -43.0))nmol/L vs.13.6 (7.6-32.4)nmol/L( t =-2.110), LP(a)-M 183(71 -361)mg/L vs.126(67 -293)mg/L(t =-2.063), age (62 ±9)years vs.(52 ±9)years(t=-7.691), hs-CRP 0.86(0.44-1.97) )mg/L vs.0.70(0.38-1.64)mg/L(t=-2.236), glucose (6.1 ±2.29 )mmol/L vs.(5.36 ±1.32 )mmol/L(t=-4.914), BA1c (6.13 ±0.98) % vs.(5.81 ±0.58) %(t=-4.842), APO(B) (1.09 ±0.33) g/L vs.(1.03 ±0.29) g/L( t=-2.407), all of the P values <0.05;The relative risk(RR)of age, glucose, LP( a)-P and LP ( a)-M are 1.067, 2.377, 1.384 and 1.342 respectively; Among the three types of plaques groups,the mean differences of age, TC, HDL-C, LDL-C and LP ( a)-P are statistically significant ( F=6.276,3.060,3.127,4.723,2.878;all of the P<0.05);The median of LP ( a)-P in the soft plaque group 20.3(8.3-48.2)nmol/L is higher than that of the mixed plaque group 15.7(7.3-26.0)nmol/L(P<0.05 ) and calcified plaque group 15.6 ( 8.1 -23.1 ) nmol/L ( P <0.05 ).The linearly regression equation of LP ( a) -M and LP( a)-P is Y=6.646X, r=0.939; Consistency test indicate the two methods are not consistent when used for grouping ( Kappa value is 0.557 ).Conclusions Serum concentration of lipoprotein(a) is an independent risk factor of CAHD, and the particle concentration of LP(a) is closely related to the characteristics of the plaques, especially to the soft plaque.

OBJECTIVETo observe the change of peripheral blood Th17 cells in patients with different kinds of CRSwNPs and the relationship between the frequency of Th17 cells and inflammatory cell density in nasal polyps tissue, and to explore the correlation between levels of peripheral blood Th17 cells and prognosis of patients with CRSwNPs.METHODSEighty one patients with CRSwNPs and 20 controls were recruited in this research. Flow cytometer was used to detect the expression of peripheral blood Th17 cells. The number per 10000μm2 of infiltrated inflammatory cells in nasal polyp tissue (including eosinophils, neutrophils, lymphocytes and plasma cells) was counted at a high-power field. The CT scores were evaluated by Lund-Mackay system and the nasal endoscopy scores were graded according to Lund-Mackay methods. RESULTSThe percentages of Th17 cells in patients with E-CRSwNPs and NE-CRSwNPs were 2.10% (3.75%, 1.40%)和1.10% (1.70%, 0.73%). There was significant difference between the two groups (Mann-WhitneyU=358.0,Z=-2.965, P=0.001). Furthermore, a positive association between the percentage of Th17 cells in peripheral blood and the eosinophil density of nasal polyp (r=0.408,P<0.001) was demonstrated. The percentage of Th17 cell in peripheral blood was significantly correlated with the endoscopic score of CRSwNPs at third month after the operation (r=0.458, P<0.001).CONCLUSIONThl7 might be involved in the pathogenesis and prognosisof eosinophilic CRSwNPs.

"Target trial emulation" (TTE), as a new framework in real-world research, has been formally established in recent years. It can be used to guide the evaluation of the effectiveness and safety of medical interventions based on real-world data for observational causal inference. The core idea of this framework is to follow the principles of randomized controlled trial (RCT), emulate a corresponding RCT using real-world data, and then draw conclusions about the causal relationship between interventions and outcomes. The main implementation tips of TTE can be summarized as "3-7-2": 3 implementation steps including formulating the causal question, designing the emulation plan, and emulating the target study; 7 design elements including eligibility criteria, treatment strategies, intervention allocation, follow-up period, outcome, causal contrast of interest, and analysis plan; and control of 2 critical biases including immortal time bias and prevalent user bias. In this article, we present an overview of the development, current status, implementation steps, classic examples, advantages and limitations of TTE, and its application prospects in traditional Chinese medicine (TCM). It is hoped that this article can assist researchers in TCM to utilize this method for real-world research and contribute to the construction of a clinical evaluation system with distinctive features of TCM.

Objective: The purpose of the present study was to investigate the effects of noise competition on word perception in normal hearing (NH) children and children with cochlear implantation (CI). Methods: To estimate the contribution of noise competition on speech perception, word perception in speech-shaped noise(SSN)and 4-talker babble noise(BN) with Mandarin Lexical Neighborhood Test were performed in 80 NH children and 89 children with CI. Corrected perception percentages were acquired in each group. Results: Both signal to noise ratio (SNR) and noise type influenced the word perception. In NH group, corrected percentages of disyllabic word perception in SSN were 24.2%, 55.9%, 77.1%, 85.1% and 88.9% at -8, -4, 0, 4 and 8 dB SNR, corresponding corrected percentages of monosyllabic word were 13.9%, 39.5%, 60.1%, 68.8% and 80.1%, respectively. In BN noise, corrected percentages of disyllabic word were 2.4%, 24.3%, 55.6%, 74.3% and 86.2%, corresponding monosyllabic word were 2.3%, 20.8%, 47.2%, 61.1% and 74.8%, respectively. In CI group, corrected percentages of dissyllabic word in SSN and BN at 10 dB SNR were 65.5% and 58.1%, respectively. Corresponding monosyllabic word were 49.0% and 41.0%. For SNR=5 dB, corrected percentages of disyllabic word in SSN and BN were 50.0% and 38.1%, corresponding corrected percentages of monosyllabic word were 40.8% and 25.1%, respectively. Analysis indicated that the masking effect were significantly higher in BN compared with SSN. Conclusions Noise competition influence word perception performance significantly. In specific, the influence of noise on word perception is bigger in children with CI than in NH children. The masking effect is higher in BN noise when compared with SSN.
