Ethical review represents the core of the scientific and technological ethical governance， and its quality depends on the participation of ethics. The absence of ethics and ethical experts will compromise the quality of the review. According to the spirit of the Guidelines on Strengthening the Governance over Ethics in Science and Technology， this paper analyzed the process of separating scientific and technological ethics from the field of scientific research morality， clarified the ethical attributes of ethical review， and argued that scientific research and technological innovation activities originated from ethics. On this basis， the fundamental principle of “ethics first” was proposed， aiming to proactively embed ethical considerations throughout the entire process of scientific and technological activities. This principle was the primary requirement for ensuring governance effectiveness and can also eliminate the risk of ethics being obscured in ethical governance. In practice， “ethics first” manifested specifically in dimensions such as prioritizing academic systems， prioritizing publicity， education， and training， as well as further advancing ethical considerations.

Objective To evaluate the clinical efficacy of a novel sleep-aid decoction in treating elderly insomnia patients with different traditional Chinese medicine (TCM) constitutional types, and its effects on neurotransmitter and inflammatory factor levels. Methods A total of 200 patients with four different TCM constitutions-peaceful, Qi-deficient, Yin-deficient, and Yang-deficient-were recruited. Peripheral blood neurotransmitter and inflammatory factor levels were measured for variations among insomnia patients across different constitutions. These patients were treated using the novel sleep-aid decoction, the effects of which were evaluated based on changes in neurotransmitters and inflammatory factors. Results Compared to the peaceful constitution group, insomnia patients with Qi-deficient, Yin-deficient, and Yang-deficient constitutions exhibited significantly elevated baseline levels of neurotransmitters (5-HT, GABA) and inflammatory factors (IL-6, TNF-α, IL-1β, CRP). Following the treatment, the Qi-deficient and Yin-deficient groups showed a marked increase in 5-HT levels, restored balance of Glu, GABA, and melatonin, and significant reductions in IL-6 and TNF-α levels. The overall effective rate was 83.5%, with optimal efficacy observed in the Qi-deficient (97.72%) and Yin-deficient (95.34%) groups. Conclusion The novel sleep-aid decoction is effective in treating insomnia in elderly patients, with the best results observed in the Qi-deficient and Yin-deficient constitution groups.

Objective:To analyze the clinical characteristics and prognostic factors of patients with acute low-frequency hearing loss（ALHL） and explore the potential role of migraine in its pathogenesis. Methods:A total of 56 ALHL patients treated at our outpatient clinic from June 2024 to January 2025 were randomly divided into two groups: a standardized treatment group and an anti-migraine treatment group. The standardized group received oral/intravenous steroids + oral/intravenous Ginkgo biloba extract, while the anti-migraine group received postauricular steroid injection/oral steroids + oral flunarizine for 2 weeks. Audiological, clinical, and psychological characteristics were collected, and statistical analysis was performed to assess clinical features and treatment outcomes, exploring the potential mechanism of migraine in ALHL. Results:The anti-migraine treatment group showed a significantly higher recovery rate than the standardized treatment group（92.86% vs 71.43%, P=0.036）. Among the anti-migraine group, 6 patients（21.43%） had a history of ALHL, 13（46.43%） had a confirmed migraine history, 26（92.86%） had anxiety, 26（92.86%） had depression, 5（17.86%） had irritable bowel syndrome, 21（75.00%） had sleep disorders, and 1（3.57%） experienced recurrence within 6 months. Conclusion:Anti-migraine therapy significantly improves the recovery rate in ALHL patients, suggesting that migraine may have a certain correlation with the pathogenesis of acute low-frequency hearing loss.

OBJECTIVE: To investigate the current status of early pain and agitation management in critically ill patients in Guizhou Province. METHODS: A retrospective study was performed using data collected from a quality control activity conducted between April and June 2021 in non-provincial public hospitals with general intensive care unit (ICU) in Guizhou Province. Hospital-level data included hospital name and grade, ICU staffing, and number of ICU beds. Patient-level data included characteristics of patients treated in the general ICU on the day of the survey (e.g., age, sex, primary diagnosis), as well as pain and agitation assessments and the types of analgesic and sedative medications administered within 24 hours of ICU admission. RESULTS: A total of 947 critically ill ICU patients from 145 hospitals were included, among which 104 were secondary-level hospitals and 41 were tertiary-level hospitals. Within 24 hours of ICU admission, 312 (32.9%) critically ill patients received pain assessments, and 277 (29.3%) received agitation assessments. Among the pain assessment tools, the critical care pain observation tool (CPOT) was used in 44.2% (138/312) of critically ill ICU patients, with a significantly higher usage rate in tertiary hospitals compared to secondary hospitals [52.3% (69/132) vs. 38.3% (69/180), P < 0.05]. The Richmond agitation-sedation scale (RASS) was used in 93.8% (260/277) of critically ill ICU patients for agitation assessment, with no significant difference between hospital levels. Among the 947 critically ill patients, 592 (62.5%) received intravenous analgesics within 24 hours, with remifentanil being the most commonly used [42.9% (254/592)]; 510 (53.9%) received intravenous sedatives, with midazolam being the most frequently used [60.8% (310/510)]. Mechanical ventilation data were available for 932 critically ill patients, of whom 579 (62.1%) received mechanical ventilation and 353 (37.9%) did not. Compared with non-ventilated patients, ventilated patients had significantly higher rates of analgesic and sedative use [analgesics: 77.9% (451/579) vs. 38.8% (137/353); sedatives: 71.8% (416/579) vs. 25.8% (91/353); both P < 0.05]. In terms of analgesic selection, ventilated patients were more likely to receive strong opioids than non-ventilated patients [85.8% (95/137) vs. 69.3% (387/451), P < 0.05]. For sedatives, ventilated patients preferred midazolam [66.6% (277/416)], whereas non-ventilated patients more often received dexmedetomidine [45.1 (41/91)]. Blood pressure within 24 hours of ICU admission were available for 822 critically ill patients, of whom 245 (29.8%) had hypotension and 577 (70.2%) did not. Compared with non-hypotensive patients, hypotensive patients had significantly higher rates of analgesic and sedative use [analgesics: 74.7% (183/245) vs. 59.8% (345/577); sedatives: 65.7% (161/245) vs. 51.3% (296/577); both P < 0.05], but there was no significant difference in the choice of analgesic or sedative agents between the two groups. CONCLUSIONS The proportion of critically ill ICU patients in Guizhou Province who received standardized pain and agitation assessments was relatively low. The most commonly used assessment tools were CPOT and RASS, while remifentanil and midazolam were the most frequently used analgesic and sedative agents, respectively. Secondary-level hospitals had a lower rate of using standardized pain assessment tools compared to tertiary-level hospitals. Mechanical ventilation and hypotension were associated with the use of analgesic and sedative medications.

Objective To explore the relationship between hemoglobin/red blood cell distribution width ra-tio(Hb/RDW)and chemotherapy sensitivity and prognosis in patients with oral squamous cell carcinoma(OSCC).Methods A total of 150 patients with advanced OSCC admitted to the hospital from January 2017 to January 2021 were selected into the study group.150 patients with other oral diseases who were diagnosed and treated for non-OSCC in the hospital during the same period were selected into the control group.Another 100 healthy subjects who underwent physical examination in the hospital during the same period were selected into the healthy group.Patients with OSCC were treated with chemotherapy,and blood routine indexes were detec-ted by automatic blood analyzer,and Hb/RDW ratio was calculated.Hb,RDW and Hb/RDW ratio were com-pared between the two groups and the relationship between Hb/RDW ratio and the sensitivity and prognosis of OSCC patients with chemotherapy were analyzed.The factors affecting the sensitivity of OSCC patients to chemotherapy were explored by multivariate Logistic regression.Results Hb and Hb/RDW in the study group were significantly lower than those in the control group and the healthy group,and RDW levels were significantly higher than those in the control group and the healthy group(P＜0.05).The patients with OS-CC were divided into high Hb/RDW group and low Hb/RDW group using the median Hb/RDW ratio(8.16)as the cut off value.The total effective rate of chemotherapy in Hb/RDW high ratio group was 70.67％,which was higher than that in Hb/RDW low ratio group 53.33％(P＜0.05).According to the sensitivity of chemo-radiotherapy,the study group was divided into sensitive group(n=103)and resistant group(n=47).The proportion of patients with stage Ⅳ,low differentiation and lymph node metastasis in resistance group was higher than that in sensitive group(P＜0.05).Multivariate Logistic regression analysis shows that TNM stage Ⅳ(OR=2.512,95％CI:1.588-3.973),low tumor differentiation(OR=2.237,95％CI:1.427-3.938),lymph node metastasis(OR=2.821,95％CI:1.607-4.951),Hb/RDW≤8.16(OR=3.540,95％CI:2.001-6.261)were risk factors for chemotherapy sensitivity in cases with OSCC(P＜0.05).The 3-year survival rate of OSCC cases in the high Hb/RDW group was 74.67％(56/75)and that in the low Hb/RDW group was 58.67％(44/75),There was a statistically significant difference in the 3-year survival rate between two groups(x2=4.320,P=0.038).Conclusion Hb/RDW is low expression in patients with OSCC,and is re-lated to the sensitivity and prognosis of patients with chemotherapy,which is expected to be a potential mark-er for predicting the sensitivity and prognosis of OSCC.

OBJECTIVE: To explore the genetic basis for a boy affected with Cohen syndrome. METHODS: A boy admitted to Children's Hospital of Nanjing Medical University in January 2021 was selected as the study subject. Genome DNA was extracted from peripheral blood samples from the child and his parents. Whole exome sequencing (WES) was carried out. And candidate variants were verified by Sanger sequencing. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 202106060-1). RESULTS: WES revealed that the child has harbored compound heterozygous variants of the VPS13B gene, namely c.1563+1G>A and c.3007insC (p.A1003Afs*13), which were inherited from his mother and father, respectively. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were rates as pathogenic. The c.3007insC (p.A1003Afs*13) was unreported previously. CONCLUSION The compound heterozygous variants c.1563+1G>A and c.3007insC (p.A1003Afs*13) of the VPS13B gene probably underlay the pathogenesis of Cohen syndrome in this child. Above finding has enriched the mutational spectrum of VPS13B gene.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

The ethics committee of organ transplantation technology and clinical application in a hospital has encountered some difficulties and typical cases in its review work and practice for many years. Sometimes, it is difficult to make a decision in these dilemmas. Based on the previous experience of the hospital in the ethical review of organ donation and transplantation, combined with two typical cases, this paper discussed and analyzed two review points of whether the voluntary unpaid donation and the principle of informed consent were met, and whether the risk-benefit ratio was reasonable, and put forward relevant ethical and legal countermeasure for further research by institutional ethics committees and other parties, in order to provide reference for discussing the practical problems and ethical confusion of ethical review of organ donation and transplantation.

Objective:To evaluate the robustness of fully automated adaptive planning for Ethos online adaptive radiotherapy (ART) based on the intelligent optimization engine (IOE).Methods:Clinical data of 11 stage ⅠB cervical cancer patients admitted to Peking Union Medical College Hospital between June 2021 and June 2022 were retrospectively analyzed. Original planning images and iterative cone-beam computed tomography (iCBCT) images of each radiotherapy treatment were acquired, and all patient data were imported into the Ethos simulator. IOE-based 9-field automatic plan generation was performed for 11 patients using Ethos, and the generated plans were sent to online adaptive radiotherapy simulation to obtain each online adaptive radiotherapy plan (273 fractions in total) and complete the simulated treatment. For comparison, manual plan design was performed based on the images and contoured structures used for online adaptive radiotherapy planning, and the manually plans created with evenly divided 9 fields. Dosimetric parameters, plan complexity parameters, and Mobius quality assurance (QA) pass rates were collected to compare and evaluate the robustness of the online adaptive radiotherapy plan in terms of organs at risk (OAR), target volume dosimetric parameters, and plan complexity by using paired t-test or rank sum test. Results:The online adaptive plan of cervical cancer had comparable planning target volume (PTV) coverage compared to the manual plan. For the clinical target volume (CTV) D 99%, online adaptive plan was significantly higher than the manual plan [(45.93±0.36) vs. (45.32±0.31) Gy, P<0.001]. For hot dose area, the maximum point dose (PTV D max) of adaptive plan was significantly higher than the manual plan [(49.89±1.25) vs. (48.48±0.77) Gy, P<0.001], but the PTV D 1% of adaptive plan was significantly lower than the manual plan [(47.22±0.29) vs. (47.59±0.48) Gy, P<0.001]. There was no statistical difference in the conformal index ( P=0.967). And there was significant difference in the homogeneity index, with same medians and less dispersion in adaptive plan ( P<0.001). For OAR dose, bladder D mean, rectal V 40 Gy, small intestine D mean of adaptive plan was slightly higher than that of the manual plan; the rectal D mean, small intestine D 2 cm3 of the adaptive plan was slightly lower than that of manual plan; dosimetric parameters of right and left femoral heads, spinal cord and bone marrow of the adaptive plan were better than those of manual plan. The adaptive plan had more monitor units (MU) than the manual plan, but the complexity of the adaptive plan was significantly lower than that of the manual plan (0.135±0.012 vs. 0.151±0.015, P<0.001). For Mobius γ pass rate (5%/3 mm), both adaptive and manual plans met clinical requirements. Conclusion:Ethos cervical cancer online adaptive plan, which is based on the IOE engine, demonstrates good robustness and ensures the quality of online adaptive plans generated for each treatment fraction.
