Objective To investigate the possible risk factors for prognosis of diffuse alveolar hemorrhage (DAH) in children and to improve the recognition of the disease.Methods The study included 62 DAH pediatric patients hospitalized from January, 2006 to January, 2016. Clinical data were retrospectively analyzed. According to the basic diseases, children were divided into immune associated DAH and non-immune associated DAH to explore the effect of early glucocorticoid treatment on the two groups of DAH. Based on the prognosis, the patients were divided into the death group and the survival group to analyze its related risk factors.Results Of the 62 patients, 20 were of immune associated DAH, 42 of non-immune associated DAH. There was no signiflcant difference of early treatment with glucocorticoid between the two groups (P>0.05). In our cohort, 30 patients died, the total mortality was 48.4% (30/62). Pediatric critical illness score may be the independent risk factor for DAH mortality.Conclusions DAH is an acute, life-threatening event, the lower the pediatric critical illness score, the higher risk of death.

Objective To determine the thermal conductivity under different temperatures and concentrations, and specific heat capacity under different concentrations of water extracts of Salvia Miltiorrhiza Radix et Rhizoma; To establish the mathematical model of thermal conductivity-temperature, thermal conductivity-concentration, thermal conductivity-temperature-concentration and specific heat capacity-concentration of water extracts of Salvia Miltiorrhiza Radix et Rhizoma. Methods Thermal conductivity and specific heat capacity were measured by the instantaneous double hot wire thermal conductivity meter and the electrothermal specific heat capacity meter. Excel, 1stOpt and MATLAB were used to analyze the experimental data. Results The method of using brix to facilitate and accurately characterize the concentration was established. The relationship between the thermal conductivity and the temperature and the concentration of water extracts of Salvia Miltiorrhiza Radix et Rhizoma were all linearly negative (λ=a-bT, λ=a-bC), and the influence of temperature and concentration on the thermal conductivity had a certain interaction. λ=a-bC-cT-dCT could be used as the temperature and the concentration on the thermal conductivity of the integrated role model. And the specific heat capacity of the extract was negatively correlated with the concentration (cp=a-bC). Conclusion The thermal conductivity and the specific heat capacity of the extract of water extracts of Salvia Miltiorrhiza Radix et Rhizoma are different at different temperatures and concentrations, and the model can be used to characterize the changing law of thermodynamics of the extracts. It can provide guidance significance for the thermal characteristics analysis in TCM pharmaceutical process and TCM production equipment selection and design, and production process control.

OBJECTIVE:
To investigate the surgical effect and complications of arytenoid resection in bilateral vocal cord fold paralysis(BVFP) patients via endoscopic laser approach and external cervical approach.
METHOD:
A total seventy-eight BVFP patients who underwent arytenoid resection surgery via endoscopic laser approach (laser group, n=30) or external cervical approach (external cervical group, n=48) were enrolled in this study. Videostroboscopy, vocal perception evaluation, maximum phonation time (MPT) text were preformed in all patients both preoperatively and postoperatively. The decannulation rate was also calculated.
RESULT:
Videostroboscopy showed that vocal fold on the operated side in both groups could abduct to various extent postoperatively, which showed significant difference when compared with preoperative abductive movements (P<0. 05). Postoperative glottal closure showed various increment in both groups. However, when with preoperative glottal closure, external cervical group showed significant difference (P < 0. 05), while laser group showed no significant difference (P> 0. 05). Postoperative videostroboscopy showed no significant difference in vocal fold position and glottal closure between these two groups(P>0. 05). Vocal perceptual evaluation(RBH score) showed a significant deterioration in voice quality postoperatively in both groups respectively (P<. 05). Postoperative MPT values showed no significant difference between the two groups (P>. 05). However, they were significantly shorten/shorter than preoperative ones in these two groups respectively (P<0. 05). The overall decannulation rate were 90. 0% and 95. 8% for laser group and external cervical group respectively. In Both groups, patients presented aspiration symptoms postoperatively, except one patient of external cervical group who developed pneumonia due to recurrent aspiration.
CONCLUSION
Arytenoid resection surgery via both endoscopic laser approach and external cervical approach can both enlarge glottic area so as to solve respiration problems, in BVFP patients. Two kinds of surgery have obvious voice damage.

Objective:
This study aimed to translate the English version of the Perceived Competence Scale for Disaster Mental Health Workforce (PCS-DMHW) into Chinese, and to test its reliability and validity in Chinese mental health workers.
Methods:
With the consent of Professor Choi, Keimyung University, Korea, and the authorization of the scale, the English version of PCS-DMHW was translated, retranslated and culturally debugged to form the Chinese version of PCS-DMHW. The general information questionnaire and the Chinese version of PCS-DMHW scale were used to investigate 706 mental health workforce from 9 tertiary hospitals in Sichuan province in China from March 24, 2020 to April 14, 2020. The Cronbach’s α coefficient was used to evaluate the internal consistency reliability of the scale, and the test-retest correlation coefficient r was used to evaluate the test-retest reliability of the scale. The content validity indexes (CVI) and exploratory factor analysis (EFA) was used separately for evaluating the content validity and structure validity of the scale.
Results:
The Cronbach’s α coefficient of the Chinese version of PCS-DMHW total scale, individual competences and organizational competences subscale was 0.978, 0.956, and 0.964, respectively. The test-retest reliability of the total scale, individual competences and organizational competences subscale was 0.949, 0.932 and 0.927, respectively. The item-level CVI of all scale were ranged from 0.833–1.000, the scale-level CVI (S-CVI)/universal agreement of the total scale, individual competences and organizational competences subscale was 0.833, 0.875, and 0.857, respectively, and the S-CVI/average was 0.972, 0.979, and 0.976, respectively. EFA showed that two principal components were extracted from the subscale of individual competences and organizational competences.
Conclusion
The Chinese version of PCS-DMHW has good reliability and validity, and can be widely used in China.
