Cassiae Semen is a substance with both edible and medicinal uses approved by the National Health Administration， and it is widely used in health food products in China. In this study， an information database of Cassiae Semen-based health food products was constructed， and the common patterns of functional claims， major raw materials， and dosage forms were analyzed. The Apriori algorithm and network method were used to analyze the association rules of high-frequency ingredients with the three major functional claims： Maintaining blood lipid （cholesterol/triglyceride） level， controlling fat， and relaxing bowel. Secondly， based on the positioning and regulatory requirements of health food and the recent research progress in Cassiae Semen， this paper analyzed the problems in technology review and product development from safety， function claim， and quality controllability. Finally， suggestions were put forward to promote the inheritance and carry forward China's traditional healthcare culture and the achievement of the Healthy China Initiative. These suggestions included classifying and optimizing the access management of health food， innovating the traditional healthcare function claims， and strengthening the quality system construction and information disclosure of post-marketing evaluation.

To summarize the nursing experience of a patient with lower limb lymphedema treated with latissimus dorsi lymph node flap transplantation combined with lymphatic vessel venous anastomosis. The main contents of nursing included refining the observation steps and accurately evaluating the blood supply of the skin flap; real time dynamic communication between medical WeChat images and text, and targeted treatment; implementing personalized disease management to prevent complications; adopting an integrated medical and nursing remote follow-up model to improve follow-up efficiency. After 20 days of careful nursing, the patient′s skin flap had good blood circulation and no vascular crisis or skin flap necrosis after surgery One week after surgery and 1 to 3 months of follow-up, the degree of swelling in the affected limb significantly decreased and the skin softened significantly.

Objectives:To investigate the predictive effect of regional homogeneity (ReHo) from resting-state functional magnetic resonance imaging (rs-fMRI) in acute phase on memory function of chronic phage in ischemic stroke patients and the effects of residual learning (REL) on the predictive performance of machine learning models.Methods:From June 2019 to June 2021, rs-fMRI data of one-week after stroke (acute phase) were collected from 35 first-time ischemic stroke patients, and their memory scores were assessed by the Rey auditory verbal learning test (RAVLT) at 6 months after stroke (chronic phase). Using ReHo from rs-fMRI data in acute phase of ischemic stroke patients, the support vector regression (SVR) and the REL-based SVR (REL-SVR) were constructed to predict the patients’ memory scores at 6 months after stroke, and the performance of the two models was compared using Pearson correlation coefficient.Results:Based on the ReHo from acute phase, the correlation coefficient between the predicted values and the true scores from the SVR model was r=0.524, P=0.001, while the correlation coefficient obtained by the REL-SVR model was r=0.671, P<0.001. Brain regions with relatively higher weights such as Temporal_Pole_Mid_R (weight value: 1.03), Temporal_Mid_R(weight value: 1.03), Temporal_Inf_R (weight value: 1.03), Occipital_Mid_R (weight value: 0.57), Frontal_Mid_L (weight value: 0.32), Frontal_Sup_Medial_L (weight value: 0.53), SupraMarginal_L (weight value: 1.54), Calcarine_L (weight value: 0.65), Lingual_L (weight value: 0.58), Cuneus_L (weight value: 0.65), Precuneus_L (weight value: 0.83), cerebellum(weight value>1.0) made larger contributions to the prediction model. Conclusions:ReHo in the acute-phase can effectively predict memory in the chronic phase of ischemic stroke patients. Furthermore, REL can improve the performance of the traditional SVR model and achieve higher predictive accuracy.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Objective:To investigate whether etomidate affects inflammatory response and apoptosis of PC12 cells induced by hypoxia by regulating miR-142-3p.Methods:PC12 cells were pretreated with different doses(2,6,12 μmol/L)of etomidate to establish hypoxia model;PC12 cells that transfected with miR-142-3p mimics or inhibitors were pretreated with 0 or 12 μmol/L of etomidate to establish hypoxia model.Cell viability,apoptosis and protein(CyclinD1,Cleaved-caspase-3)expressions were detected by CCK-8 method,flow cytometry and Western blot,respectively.ELISA was used to detect levels of inflammatory factors TNF-α,IL-1β,IL-6.Expression of miR-142-3p was detected by RT-qPCR.Results:Etomidate increased hypoxia-induced PC12 cells activity and expres-sion of CyclinD1 protein and miR-142-3p,while decreased cell apoptosis rate,Cleaved-caspase-3 protein expression and levels of inflammatory factors TNF-α,IL-1β,IL-6(P<0.05).Up-regulation of miR-142-3p increased activity and expression of CyclinD1 pro-tein of hypoxia-induced PC12 cells,while decreased cell apoptosis rate,Cleaved-caspase-3 protein expression and levels of inflamma-tory factors TNF-α,IL-1β,IL-6(P<0.05).Down-regulation of miR-142-3p reversed effects of etomidate on hypoxia-induced PC12 cell activity,apoptosis and expressions of inflammatory factors(P<0.05).Conclusion:Etomidate can reduce inflammatory response and apoptosis of PC12 cells induced by hypoxia,and its mechanism may be related to the up-regulation of miR-142-3p expression in cells.

The mesencephalic astrocyte-derived neurotrophic factor (MANF) has been recently identified as a neurotrophic factor, but its role in hepatic fibrosis is unknown. Here, we found that MANF was upregulated in the fibrotic liver tissues of the patients with chronic liver diseases and of mice treated with CCl₄. MANF deficiency in either hepatocytes or hepatic mono-macrophages, particularly in hepatic mono-macrophages, clearly exacerbated hepatic fibrosis. Myeloid-specific MANF knockout increased the population of hepatic Ly6C^high macrophages and promoted HSCs activation. Furthermore, MANF-sufficient macrophages (from WT mice) transfusion ameliorated CCl₄-induced hepatic fibrosis in myeloid cells-specific MANF knockout (MKO) mice. Mechanistically, MANF interacted with S100A8 to competitively block S100A8/A9 heterodimer formation and inhibited S100A8/A9-mediated TLR4-NF-κB signal activation. Pharmacologically, systemic administration of recombinant human MANF significantly alleviated CCl₄-induced hepatic fibrosis in both WT and hepatocytes-specific MANF knockout (HKO) mice. This study reveals a mechanism by which MANF targets S100A8/A9-TLR4 as a "brake" on the upstream of NF-κB pathway, which exerts an impact on macrophage differentiation and shed light on hepatic fibrosis treatment.

The clinical utilization of doxorubicin (Dox) in various malignancies is restrained by its major adverse effect: irreversible cardiomyopathy. Extensive studies have been done to explore the prevention of Dox cardiomyopathy. Currently, ferroptosis has been shown to participate in the incidence and development of Dox cardiomyopathy. Sorting Nexin 3 (SNX3), the retromer-associated cargo binding protein with important physiological functions, was identified as a potent therapeutic target for cardiac hypertrophy in our previous study. However, few study has shown whether SNX3 plays a critical role in Dox-induced cardiomyopathy. In this study, a decreased level of SNX3 in Dox-induced cardiomyopathy was observed. Cardiac-specific Snx3 knockout (Snx3-cKO) significantly alleviated cardiomyopathy by downregulating Dox-induced ferroptosis significantly. SNX3 was further demonstrated to exacerbate Dox-induced cardiomyopathy via induction of ferroptosis in vivo and in vitro, and cardiac-specific Snx3 transgenic (Snx3-cTg) mice were more susceptible to Dox-induced ferroptosis and cardiomyopathy. Mechanistically, SNX3 facilitated the recycling of transferrin 1 receptor (TFRC) via direct interaction, disrupting iron homeostasis, increasing the accumulation of iron, triggering ferroptosis, and eventually exacerbating Dox-induced cardiomyopathy. Overall, these findings established a direct SNX3-TFRC-ferroptosis positive regulatory axis in Dox-induced cardiomyopathy and suggested that targeting SNX3 provided a new effective therapeutic strategy for Dox-induced cardiomyopathy through TFRC-dependent ferroptosis.

Objective: To understand the prevalence of school bullying and depressive symptoms among the Han, Yi, and Tibetan adolescents in western China, and to explore the relationships between bullying roles, bullying frequency and depression symptoms. Methods: A combination method of typical sampling and cluster sampling was used to recruit 3 115 participants from six primary and middle schools in Cangxi County and Ganluo County in Sichuan Province, and Lhasa City in Tibet Autonomous Region from April to November 2020. All participants completed self filled questionnaires. Multiple Logistic regression was used to analyze the association between school bullying and depression symptoms. Results: A total of 881 participants (28.3%) had experienced school bullying in the past 6 months, and 892 participants(28.6%) were detected with depressive symptoms. The rates of school bullying in the Han, Yi, and Tibetan adolescents were 20.5%, 46.4% and 23.8%, respectively. Among them, the rates of victims were 15.3%, 25.0% and 11.8%, respectively; the rates of bully were 2.3%, 5.7% and 6.7%, respectively; the rates of bully victims were 2.9%, 5.7% and 5.4%, respectively. The prevalence of depressive symptoms in the Han, Yi, and Tibetan adolescents were 20.4%, 37.9% and 36.5%, respectively. After adjusting for age, grade, ethnicity, smoking, and drinking, the odds for depressive symptoms among victims ( AOR=1.98, 95%CI =1.61- 2.45 ), bully ( AOR=2.63, 95%CI =1.81-3.82), and bully victims ( AOR=3.33, 95%CI =2.44-4.54) were significantly higher than those without school bullying experience( P <0.01). And the risks increased with the increasing bullying frequency. Conclusion School bullying and depressive symptoms of the Yi and the Tibetan adolescents in western China were higher than those of the Han adolescents. Meanwhile, participation in school bullying and the high frequency of bullying were closely related to depressive symptoms. Future interventions should pay attention to various bullying roles and minority adolescents.
