Objective: To determine the association between pulse pressure and the risk of new-onset diabetes in hypertensive patients. Methods: In this prospective cohort study, hypertensive patients from the Kailuan Study, who were diagnosed in 2006-2007 check-up, were screened for enrollment. Participants who finished the biennial follow-up until December 31, 2017 were finally included in this analysis. The primary outcome was incident diabetes development. The pulse pressure variables were divided into quartiles (Q₁-Q₄), and the Kaplan-Meier curve was used to examine and estimate the cumulative incidence of new-onset diabetes among quartiles. Cox proportional hazards regression model was performed to explore the association between pulse pressure and the risk of new-onset diabetes in hypertensive patients. Results: During an average follow-up of 8.17 years, 6 617 new-onset diabetes were identified out of the 32 917 hypertensive patients with no history or evidence of diabetes in 2006-2007 check-up. Participants were classified into quartiles according to pulse pressure levels as follows: Q₁ group(<41 mmHg (1mmHg=0.133kPa))(n=7 995); Q₂ group(41-<51 mmHg) (n=8 196); Q₃ group (51-<61 mmHg) (n= 8 270); Q₄ group (≥61 mmHg) (n=8 456). The cumulative incidences of new-onset diabetes across the quartiles were 16.94%, 19.61%, 21.07%, and 22.33%, respectively, with the incidence density was 20.27, 23.20, 24.92, and 26.10 per 1 000 person-years, respectively. The cumulative incidence of new-onset diabetes increased in proportion with increasing pulse pressure levels (P<0.01 by the Log-rank test). After multivariate adjustment, compared with the first quartile, the hazard ratios for new-onset diabetes in the third and fourth quartiles were 1.13 (95%CI 1.04-1.22, P<0.01) and 1.14 (95%CI 1.05-1.24, P<0.01), respectively. The risk of new-onset diabetes increased 5%(HR=1.05, 95%CI 1.02-1.08, P<0.01) with the fractional pulse pressure increased per 1 SD (0.13). Findings from the three sensitivity analyses were consistent with the main results in this cohort. Conclusions: Pulse pressure at baseline is positively associated with the incidence of new-onset diabetes among hypertensive individuals, and pulse pressure is an independent risk factor for the development of diabetes in hypertensive patients.

Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Objective: To evaluate the auditory efficacy and subjective satisfaction of adhesive bone conduction hearing aid in children with unilateral congenital aural atresia (UCAA). Methods: Ten subjects (5 males and 5 females) diagnosed with UCAA with an average age of 8.3 years old (ranged from 5 to 15) were included in Beijing Tongren Hospital, Capital Medical University from January to August 2019. The free sound field hearing threshold, word recognition score in quiet, speech reception threshold in noise and sound localization ability (results were measured by RMS error) tests were performed in unaided and aided situation, respectively. Subjective satisfaction questionnaires were also distributed to subjects. Paired t test and Wilcoxon signed rank test were used as statistical analysis methods. Results: The average hearing threshold in aided condition was improved by (21.9±4.4) dB (t=15.8，P<0.05). Speech recognition abilities were generally improved both under quiet and noise (P<0.05);however, when the binaural summation, squelch and head shadow effects were analyzed respectively, the binaural squelch effect was not statistically improved (P>0.05), while the other effects were improved in aided condition (P<0.05). In sound localization test, there was no significant difference of the RMS error value between the unaided and aided situation (P>0.05). The subjects got high satisfaction rates in three subjective questionnaires. Conclusion: The adhesive bone conduction hearing aid can provide significant audiological benefit for children with UCAA as well as raising the quality of their life.

BACKGROUND: Prospective analyses have yet to identify a consistent relationship between sleep duration and the incidence of gastrointestinal (GI) cancers. The effect of changes in sleep duration on GI cancer incidence has scarcely been studied. Therefore, we aimed to examine the association between baseline sleep duration and annual changes in sleep duration and GI cancer risk in a large population-based cohort study. METHODS: A total of 123,495 participants with baseline information and 83,511 participants with annual changes in sleep duration information were prospectively observed from 2006 to 2015 for cancer incidence. Cox proportional-hazards models were used to calculate hazard ratios (HRs) and their confidence intervals (CIs) for GI cancers according to sleep duration and annual changes in sleep duration. RESULTS: In baseline sleep duration analyses, short sleep duration (≤5 h) was significantly associated with a lower risk of GI cancer in females (HR: 0.31, 95% CI: 0.10-0.90), and a linear relationship between baseline sleep duration and GI cancer was observed (P = 0.010), especially in males and in the >50-year-old group. In the annual changes in sleep duration analyses, with stable category (0 to -15 min/year) as the control group, decreased sleep duration (≤-15 min/year) was significantly associated with the development of GI cancer (HR: 1.29; 95% CI: 1.04-1.61), especially in the >50-year-old group (HR: 1.32; 95% CI: 1.01-1.71), and increased sleep duration (>0 min/year) was significantly associated with GI cancer in females (HR: 2.89; 95% CI: 1.14-7.30). CONCLUSIONS Both sleep duration and annual changes in sleep duration were associated with the incidence of GI cancer.
