One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

Objective:To construct a biosafety evaluation index system for major emergency public health events in medical institutions.Methods:Based on previous laboratory biosafety evaluation work, relevant regulations and standards on biosafety in China were collected through literature research and expert consultations. Candidate indicators for constructing the biosafety evaluation system for major emergency public health events in medical institutions were selected, and a framework was established. Two rounds of expert questionnaires were conducted to determine the content of the index system based on experts′ evaluation, and each indicator′s relevance and importance were scored. Finally, two rounds of Delphi consultations were carried out, and the Analytic Hierarchy Process (AHP) was applied to calculate the weights of indicators.Results:The response rates for the total four rounds of questionnaire surveys were all 100%. The first two rounds focused on determining the framework, while the latter two focused on determining the weights for each indicator. The authority coefficients of the expert consultations for the two rounds of weights were 0.65 and 0.70, respectively, indicating the reliability of the research results. In the final round of survey, the Kendall′s coefficients of concordance at each level were all greater than 0.1. Through statistical testing, the P-values were all less than 0.05, indicating good coordination of expert opinions. Ultimately, we established an operational biosafety evaluation system for major emergency public health events in medical institutions, consisting of 4 primary indicators, 26 secondary indicators, and 119 tertiary indicators, with additional deduction items, bonus items, unacceptable items, and monitoring indicators.Conclusions:Based on scientific theory, a biosafety evaluation system for major emergency public health events in medical institutions was constructed, achieving the integration of routine and emergency measures. This system can be used for self-assessment of laboratory biosafety during emergency public health events, addressing the lack of unified standards in biosafety evaluation. Through regular self-assessment, it can enhance the level of biosafety management in medical institution laboratories, to realize the value of application and dissemination.

ObjectiveTo explore the construction of a risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions, and to provide a reference standard for the prevention and control of infectious diseases, staff training and system construction in childcare institutions. MethodsBy combining the Delphi method with the literature review and expert consultation, the hierarchical dimensions and items at all levels of the risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions were constructed, and the weighting coefficients were determined by analytic hierarchy process. ResultsA total of 14 experts from the field of childcare institutions, infectious disease control, child healthcare and health supervision participated in the Delphi consultation. The system consisted of four core dimensions: organizational management, team building, hardware equipment, and infectious disease surveillance and disposal, with the weighting coefficients of 0.285 9, 0.261 6, 0.204 3 and 0.248 2, respectively. The evaluation indicator system consisted of 4 primary indicators, 15 secondary indicators and 45 tertiary items. The positivity coefficients of the two rounds of Delphi consultation were 0.93 and 1.00, the authority coefficients were both 0.81, and the Kendall’s coefficient of concordance were 0.44 and 0.49, respectively (P<0.01). ConclusionThe high expert engagement and coordination indicate that organizational management and team building remain the critical priorities for infectious disease prevention and control in Shanghai’s childcare institutions. It is recommended to strengthen financial investment, improve institutional mechanisms, and enhance personnel reserves and capacity building for healthcare teachers, thereby systematically upgrading the infectious disease control capabilities of childcare institutions.

Objective:To explore the construction and validation of a nomogram model for predicting poor survival prognosis in patients with clear cell renal cell carcinoma（ccRCC）based on deep learning of pathological images.Methods:This study was an observational cohort study. The original pathological images and clinicopathological data（TCGA cohort）of 378 patients with ccRCC were obtained from the Cancer Genome Atlas Database（TCGA）for model training. A total of 301 patients with ccRCC who underwent surgical treatment at Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2010 to December 2020（Renji cohort）and 214 patients with ccRCC who underwent surgical treatment at the First People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2012 to December 2018（General cohort）were included for model validation. Their original pathological images and clinical pathological data were collected. A clustering-constrained attention and multi-instance learning method was used to accurately identify sub-regions of the images to classify and extract features of the pathological images. A deep learning-based disease-free survival prognosis prediction model（DL-DFS）was constructed through a weakly supervised learning strategy. The clinical pathological features and DL-DFS were further combined to construct a nomogram model for the clinical prognosis of ccRCC patients. Univariate and multivariate Cox regression analyses were employed to evaluate the independent risk factors for disease-free survival（DFS）. The efficacy of the predictive model were evaluated by the receiver operating characteristic curve（ROC）with area under the curve（AUC），respectively. Survival analysis was conducted using the Kaplan-Meier curve.Results:DL-DFS could accurately predict the DFS status of ccRCC patients in 5 years after surgery. Through ROC analysis in the training cohort，the AUC value reached 0.75（ P < 0.001）. In the Renji cohort and the General cohort，the AUC values were 0.65（ P < 0.001）and 0.81（ P < 0.001），respectively. Through Kaplan-Meier survival analysis，we found that DL-DFS could identify ccRCC patients with high survival risks. The hazard ratio in the training cohort was 3.86（95% CI 2.36-6.30， P < 0.001）. The hazard ratio in the Renji cohort and General cohort were 1.97（95% CI 1.03-3.80， P = 0.009）and 4.66（95% CI 1.80-12.06， P = 0.008），respectively. Univariate and multivariate Cox regression analyses indicated that DL-DFS risk score，tumor grade，and tumor stage could act as prognostic risk factors for patients with ccRCC（ P < 0.05）. Considering that age was a common prognostic risk factor for patients with renal cancer，a nomogram model was constructed by combining the DL-DFS risk score with patient age，tumor grade，and tumor stage. The AUC of this model for predicting the 5-year DFS of ccRCC patients after surgery was 0.87，which was significantly higher than that of DL-DFS（AUC = 0.74），tumor stage（AUC = 0.84），tumor grade（AUC = 0.72），and patient age（AUC = 0.56）in the TCGA cohort（all P<0.05）. In the Renji cohort and the General cohort，the AUC of the nomogram model were 0.78 and 0.86 respectively，which was significantly higher than that of DL-DFS（0.65 and 0.81），tumor stage（0.72 and 0.69），tumor grade（0.64 and 0.77），and patient age（0.56 and 0.63）. Conclusions:In this study a DL-DFS for ccRCC patients was constructed. Then a nomogram model was constructed by combining the DL-DFS risk value with patient age，tumor grade，and tumor stage. This nomogram model demonstrated superior predictive performance compared to DL-DFS alone in evaluating the DFS prognosis of ccRCC patients，which still needs to be further verified in prospective clinical studies.

ObjectiveTo investigate the effect of kinesin family member 15 （KIF15） on the proliferation of hepatocellular carcinoma （HCC） cells and its mechanism of action. MethodsTCGA and GEPIA datasets were analyzed to determine the expression of KIF15 in HCC and its effect on tumor stage and survival. Quantitative real-time PCR and Western blot were used to measure the expression level of KIF15 in human-derived HCC cell lines （HepG2， Hep3B， MHCC-97H， and LM3） and human normal liver cell line L02 cultured in vitro， and Hep3B and HepG2 were selected for subsequent studies. CCK-8 assay， plate colony formation assay， and EdU staining were performed for Hep3B cells transfected with shRNA-NC or shRNA-KIF15 and HepG2 cells transfected with LV-vector or LV-KIF15 to evaluate the viability and proliferative capacity of these cells. GSEA was used to analyze the potential signaling pathways associated with KIF15 in HCC， and Western blot was used for detection. The independent-samples t test was used for comparison of continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsThe analysis of TCGA and GEPIA datasets showed that in HCC patients， the expression of KIF15 in HCC tissue was significantly higher than that in normal tissue， and the HCC patients with high KIF15 expression tended to have a poorer prognosis. Compared with sh-NC-Hep3B， sh3-Hep3B showed significant reductions in the mRNA and protein levels of KIF15 （P<0.05）， cell viability， clone formation number， and EdU positive rate （all P<0.05）. Compared with vector-HepG2， LV-KIF15-HepG2 showed significant increases in the mRNA and protein levels of KIF15 （P<0.05）， cell viability， clone formation number， and EdU positive rate （all P<0.05）. Subcutaneous tumor assay showed that compared with sh-NC-Hep3B， sh3-Hep3B showed reductions in tumor volume and tumor weight， as well as a significant reduction in the immunohistochemical score of Ki67 and a significant increase in the immunohistochemical score of TUNEL （P<0.05）. GSEA analysis showed that the PI3K/AKT/mTOR pathway was positively correlated with KIF15 in HCC （NES=1.59， P<0.001）. Western blot showed that LY294002 could inhibit the PI3K/AKT/mTOR pathway upregulated in LV-KIF15-HepG2， and compared with LV-KIF15-HepG2， LY294002+LV-KIF15-HepG2 showed significant reductions in cell viability， clone formation number， and EdU positive rate （all P<0.05）. ConclusionKIF15 enhances the viability and proliferative capacity of HCC cells by upregulating the PI3K/AKT/mTOR signaling pathway.

Background Organic phosphate flame retardants are emerging environmental pollutants. While there have been multiple toxicities reported following organic phosphate flame retardants exposure, few studies focus on their potential developmental toxicities. It is necessary to elucidate these developmental toxicological effects and underlying mechanisms to improve risk assessments and better protect sensitive populations. Objective To evaluate potential developmental toxicities in early chicken embryos following exposure to triphenyl phosphate (TPhP) or cresyl diphenyl phosphate (CDP), to reveal TPhP and CDP’s capabilities to activate peroxisome proliferator-activated receptor γ (PPARγ) in vivo in an established chicken embryo gene reporter system, and to investigate the roles of PPARγ in TPhP/CDP-induced developmental toxicities with lentivirus-mediated in vivo gene silencing. Methods Firstly, diverse doses of TPhP and CDP were injected into the air sacs of fertilized eggs to assess the development of chicken embryos after 6 d of incubation, and an optimal dose was chosen for subsequent experiments. Subsequently, the report gene system was employed to evaluate the intraembryonic activation of PPARγ by TPhP and CDP. Eventually, PPARγ was silenced using lentivirus, and the embryos were co-treated with TPhP and CDP to further disclose the roles of PPARγ in the observed developmental toxicity. Results Following developmental exposure to TPhP or CDP, significantly lower chicken embryo weights (normalized with egg weights) were observed in the 6 d embryos (10, 30 mg·kg⁻¹ TPhP and 3, 10, 30 mg·kg⁻¹ CDP), indicating that both chemicals have general developmental toxicities and CDP is more potent. Additionally, exposure to CDP also resulted in remarkably increased sagittal brain area (normalized to embryo weights) and decreased sagittal eye area (normalized to embryo weights) (P<0.05), suggesting that CDP has specific developmental neurotoxicity and ocular toxicity. The PPARγ reporter gene experiment results revealed that rosiglitazone (positive control), TPhP, and CDP all significantly activated PPARγ relative to control (P<0.05). The potency order was rosiglitazone > CDP > TPhP. The lentivirus microinjection successfully achieved in vivo silencing of PPARγ in developing chicken embryos, and the estimated silencing efficacy was approximately 55% according to the real-time quantitative polymerase chain reaction (qRT-PCR) results. The in vivo silencing of PPARγ effectively alleviated TPhP or CDP-induced decrease of embryo weights (P<0.05), as well as CDP-induced increase of brain areas and decrease of eye areas (P<0.05). Conclusions Both TPhP and CDP can induce general developmental toxicities in early chicken embryos, and CDP is more potent than TPhP. Meanwhile, CDP can induce specific enlarged brain area and decreased eye area. The observed toxicities are associated with in vivo activation of PPARγ.

Objective To explore the clinical effect of clinical observation of supplemented wendan decoction combined with Western medicine in treating insomnia accompanied by anxiety and depression in phlegm-heat internal disturbance syndrome.Methods A total of 120 cases of insomnia with anxiety and depression comorbiditis with phlegm heat disturbance syndrome were randomly divided into control group and treatment group,60 cases in each group.The control group was given escitalopram oxalate tablet combined with dexzopiclonone tablet,and the observation group was given added Wendan decoction on the basis of the control group.Both groups were treated continuously for 6 weeks.Polysomnography monitoring parameters and heart rate variability were compared between the two groups during baseline period and visit 2(baseline period+3 months).Scale scores of the two groups were compared during baseline period,visit 1(baseline period+6 weeks)and visit 2.The content of heart rate variability includes:time domain analysis(standard deviation of normal interval(SDNN),square root of the square sum of the mean of the difference between adjacent normal interval(RMSSD)and frequency domain analysis(LF,HF,LF/HF).The scale scores included the Pittsburgh Sleep Quality Index(PSQI)and Insomnia Severity Index(ISI)to assess sleep status,and the Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Self-assessment Scale for Depression(PHQ-9)and Generalized Anxiety Disorder Scale(GAD-7)to assess anxiety and depression status.Results(1)Polysomnography monitoring:the wake time of observation group was significantly shorter than that of control group,the number of awakenings was significantly less than that of control group,and the percentage of N3 and REM was significantly higher than these of control group(P＜0.05).(2)Heart rate variability:RMSSD and HF values in the observation group were significantly higher than those in the control group,and LF/HF values were significantly lower than those in the control group(P＜0.05).(3)In terms of sleep:during the interview,PSQI total score,sleep quality,hypnotic drugs and daytime dysfunction in the observation group were significantly lower than those in the control group(P＜0.05);At the 3 months,the sleep quality,hypnotic drugs and daytime dysfunction in the observation group were significantly lower than those in the control group(P＜0.05).In terms of emotion:HAMA,HAMD and GAD-7 scores were significantly lower than those of control group at 6 weeks(P＜0.05);At the 3 months,HAMA and GAD-7 scores were significantly lower than those of control group(P＜0.05).Conclusion Supplemented Wendan decoction combined with western medicine can obviously optimize the sleep structure of insomnia patients with anxiety and depressionof phlegm-heat disturbance syndrome,improve sleep continuity and deepen sleep depth,and improve parasympathetic functional activities,contribute to sympathetic parasympathetic balance,can improve insomniaand depression symptoms recently,and significantly improve anxiety symptoms in the short term,with good safety.
