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: The study aimed to develop Questionnaire for Parental Acceptability of School based Depression Symptom Screening by Delphi method, so as to provide a reference and suggestions for promoting screening adolescents depression. Methods: The study was conducted through the literature review and two rounds of the Delphi expert consultation. The initial construction of scale dimension and item was conducted through the literature search. A survey of 12 experts from 6 different provinces, cities and regions in China was conducted, and the Delphi technique was used to collect and analyze expert opinions data about the importance and feasibility of questionnaire content. The dimensions and specific items of the questionnaire were finally determinded. Results: The response rates were 100% in both rounds of Delphi consultation. Kendall coordination degree W =0.22 ( χ 2=63.72, P <0.01), which showed the agreement of expert opinions. The initial scale consisted of 4 dimensions and 17 items, including parental cognition of school based depression screening, parental cognition of school depression screening results feedback and management, parental attitude of school based depression screening, parental utilization of mental health services. After two rounds of expert consulattion, the final scale consisted of 3 first grade dimensions including parental cognition of depression symptom, parental attitude of school based depression symptom screening and parental mental health promotion behaviour, and also cinsisted of 4 second grade dimensions including parental knowledge of depression symptom, parental attitude of school based depression symptom screening, parental choice preference of school based depression symptom screening, parental utilization of mental health services, which had a total of 25 items. Conclusion The questionnaire is developed for assessing parental acceptability of school based depression screening and associated factors. The finding will facilitate mental health services providers in the screening implementation, but further empirical research is still needed.

Objective: To study the expression of CD123 in bone marrow (BM) blasts of acute myeloid leukemia (AML) patients to explore the relationship between CD123 expression and therapeutic response and prognosis. Methods: This study retrospectively analyzed expression and distribution of CD123 in BM blasts in 137 cases of newly diagnosed AML (excluded M₃) , CD123 detected by flow cytometry≥20% was defined as positive, including 84 CD123⁺ AML and 53 CD123^- AML, efficacy and prognosis were compared between the two groups. Results: ① Among 137 patients, 84 were in group CD123⁺ (61.3%) , and 53 in group CD123^- (38.7%) . All 137 patients were classified into risk groups based on cytogenetic and molecular biology abnormalities. No significant differences were seen between the three risk groups with regard to their CD123 levels (χ²=0.861, P=0.650) . Compared with CD123^- group, the CD123⁺ group had higher WBC[47.7 (1.0-264.0) vs 22.4 (0.7-211.0) , z=-2.592, P=0.010]. ② The rates of first complete remission (CR1) and recurrence of CD123⁺ group were 54.8% (46/84) and 50.8% (32/63) , respectively; and CD123^- group were 73.6% (39/53) and 41.7% (20/48) , respectively. There was significant difference of CR1 between the two groups (χ²=5.121, P=0.027) , whereas no significant difference of the recurrence rate (χ²=0.911, P=0.340) . ③ The median dutations of OS between CD123⁺ group and CD123^- group were 20.0 (95%CI 13.1-26.9) months vs 44.0 (95%CI 23.6-47.3) months, respectively (χ²=5.874, P=0.015) ; The median durations of DFS were 7.8 (95%CI 1.4-14.1) months vs 18.6 (95%CI 0-39.7) months, respectively, no differences were observed between the two groups (χ²=2.939, P=0.086) . ④ CD123 retained an adverse prognosis value on DFS and OS within the intermediate group and patients ≤ 50 years older. Conclusions CD123 widely expressed in AML patients, which was an independent risk factor for CR1 and OS, which implicating its important role in evaluating the induction chemotherapy response and prognosis of AML.

Objective:To observe the application effect of simulation medicine teaching in clinical practice teaching of respiratory department.Methods:A total of 96 five-year undergraduate students of clinical medicine specialty from Batch 2018 were randomized into in two groups in average. The traditional teaching group conducted bedside teaching according to traditional teaching outline, and the simulation medicine group used simulated medical teaching method. The performances of theoretical knowledge and skill operations and the teaching satisfaction with the department were evaluated between the two groups. SPSS 22.0 was used for t test and chi-square test. Results:There was no significant difference in theoretical knowledge between the two groups, but the results of skill operation test and satisfaction with the department of the simulation medicine group were significantly better than those of the traditional teaching group, and the difference was statistically significant [(80.92±5.99) vs. (87.71±4.95), P<0.050; χ2=26.14, P<0.05]. Conclusion:Simulation medicine teaching is better than traditional teaching in clinical practice teaching of respiratory department, which can improve students' clinical skills and operation level, cultivate good clinical thinking for students, and improve their learning interests.

Objective: To explore the association between bedroom light at night (LAN) exposure and body mass index (BMI) in children at 1 year follow up, so as to provide new strategies for obesity prevention. Methods: From December 2021 to May 2022, cluster random sampling was conducted, involving 648 children from two primary schools in Tianchang, Chuzhou City, Anhui Province, China, to assess bedroom LAN exposure of children during sleep. A questionnaire survey and physical examination were carried out in May 2022. Multivariate linear regression was performed to analyze the correlation between bedroom LAN exposure and BMI variable quantity at 1 year follow up (May, 2023). Results: The median intensity of bedroom LAN exposure during the sleep episode was [1.11(0.35,3.24)lx] in children. The proportion of the sample exposed to an average light intensity of ≥3 lx was 27.5%, while 19.0% was exposed to a LAN intensity of ≥5 lx during the sleep episode. In the multivariable linear regression, after adjusting for covariates, including sex, baseline age, sleep duration, family monthly income, and maternal education level, exposure to a 1 h-average post bedtime LAN intensity of ≥3 lx ( β=0.25, 95%CI =0.05-0.44) and LAN≥5 lx ( β=0.34, 95% CI = 0.12-0.55) was associated with a gain of 0.25 and 0.34 kg/m 2, respectively, in the children s BMI at the 1 year follow up ( P < 0.05). Conclusions A positive correlation was found between bedroom LAN exposure and BMI variable quantity at 1 year follow up in children. Thus, reduced bedroom LAN exposure might be useful for interventions aimed at obesity prevention.
