ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect， but the specific mechanism of action has not been elaborated. Based on the transcriptome results， the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue， cell， pathological process， biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group， model group and nuciferine group（40 mg·kg^-1） according to weight. Except for the sham group， the model of middle cerebral artery occlusion（MCAO） was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery， transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue， and gene ontology（GO） and kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue， cell， pathological process， biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform（TMNP）. ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response， ion transport， cell proliferation and differentiation， and synaptic function. TMNP research found that at the tissue level， nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels， nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells， mobilizing immune cells， regulating inflammation. And at the level of biological processes and signaling pathways， nuciferine mainly acted on the processes such as vascular remodeling， inflammation-related signaling pathways， and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing， gene quantitative analysis and TMNP， the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation， affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Background: The immune system plays a critical role in the development and progression of osteoporosis and fractures. However, the causal relationships between antibody immune responses, immune cells, and these bone conditions remain unclear. This study aimed to explore these relationships using Mendelian randomization (MR) analysis. Methods: We collected complete blood count data from patients with fractures and healthy individuals and analyzed their differences. Then, we conducted a 2-sample, 2-step MR analysis to investigate the causal effects of antibody immune responses on osteoporosis and fractures, using inverse-variance weighted (IVW) as the primary method. We also explored whether immune cells mediate the pathway between antibodies and osteoporosis or fractures. Finally, we analyzed the functions and expression levels of key genes involved. Results: Overall, the fracture group exhibited increased white blood cell count, absolute neutrophil count, absolute monocyte count, platelet count, and their respective proportions, while absolute lymphocyte count, absolute eosinophil count, absolute basophil count, red blood cell count, and their proportions were decreased. We identified 44 causal relationships between antibodies and osteoporosis or fractures, with 7 supported by multiple MR methods, and 5 showing odds ratios significantly deviating from 1 in the IVW analysis. Epstein-Barr virus-related antibodies had a notable impact on osteoporosis and fractures. The human leukocyte antigen (HLA) gene family, particularly HLA-DPB1, emerged as a significant risk factor. However, immune cells were not found to mediate these effects. Conclusions This study elucidated the causal relationships between antibody immune responses, immune cells, and osteoporosis or fractures. The HLA gene family plays a crucial role in the interaction between antibodies and these bone conditions, with HLA-DPB1 identified as a key risk gene. Immune cells do not serve as mediators in this process. These findings provide valuable insights for future research.

Data on gender, age, occurrence timeframes were analyzed using t-test and χ 2 test for intergroup comparisons. Results: Annual cases were 291 (2017), 353 (2018), 483 (2019), and 503 (2023). Compared with 2017, male alcohol poisoning cases increased by 66.94% while female cases surged 104.35% by 2023. The peak incidence of alcohol poisoning among minors occurred among 16-18 year olds (85.40%), followed by 13-15 year olds (13.74%). Most cases clustered between 21:01-03:00 (60.43%), with male cases peaking at 22:01-23:00 (12.73%) and female cases peaking at 02:01-03:00 ( 11.25 %). Between 00:01-03:00, male cases progressively decreased while female cases increased. Severity distribution showed 355 mild cases (21.78%), 1 035 moderate cases (63.50%), and 240 severe cases (14.72%). Conclusions Zhengzhou region has experienced sustained growth in underage alcohol poisoning cases, predominantly occurring from evening to early morning with moderate severity, female cases demonstrate faster growth rates. Multifaceted regulatory measures should be implemented to strengthen supervision of underage drinking behaviors.

OBJECTIVE To investigate the pharmaceutical affairs management in healthcare institutions from Haidian district of Beijing， and propose countermeasures and suggestions for improving the related work. METHODS The current status of pharmaceutical affairs management in 66 healthcare institutions from Haidian district of Beijing was surveyed through on-site inspections， and the results were statistically analyzed. The inspection items included six special projects： pharmaceutical affairs management and organizational structure of pharmacy departments； drug quality management and control， prescription review， clinical application management of antimicrobial drugs， management of adverse drug events， and management of special drugs. These areas were further divided into a total of 27 specific inspection sub-items. RESULTS & CONCLUSIONS The total proportion of healthcare institutions that fully complied or basically complied with each special project was 90.9%， 97.0%， 86.3%， 90.9%， 90.9%， and 96.9%， respectively. The overall comparison among healthcare institutions that fully or substantially met the standards across medical institutions at different levels showed that the performance of tertiary healthcare institutions was better than that of secondary and primary healthcare institutions. The pharmaceutical affairs management in healthcare institutions within the jurisdiction was proceeding in an orderly manner. There is still room for improvement in further establishing and perfecting the functions of the pharmaceutical affairs management committee， implementing the 2021 Edition of Management Regulations for β -lactam Antimicrobial Skin Tests， enforcing the adverse drug reaction management system， and strengthening the refined management of narcotics and psychotropic drugs.

The objective of this study was to examine the effects of electroacupuncture on the expression of ATP-binding cassette transporter A1(ABCA1),ATP-binding cassette transporter G1(ABCG1),and class B type Ⅰ scavenger receptor(SR-B Ⅰ)genes and proteins in peritoneal macrophages of atherosclerotic rabbits.The study aimed to explore the mechanism underlying the treatment of atherosclerosis(AS)with electroacupuncture.Methods Twenty-six male New Zealand rabbits were randomly divided into the negative control group(n=7)and the modeling group(n=19)using a random number table method.The negative control group rabbits were fed a regular diet,while the modeling group was induced with a combination of high-fat feed and common carotid artery balloon injury surgery to create an AS model.After successful modeling,the rabbits in the modeling group were further divided into the model group,the electroacupuncture group,and the atorvastatin group,with 6 rabbits in each group.The rabbits in the electroacupuncture group received electroacupuncture at"'Neiguan'(PC6)","'Zusanli'(ST36)",and"'Guanyuan'(ST25)"acupoints,using a density wave,a current of 1 mA,and a frequency of 4 Hz/20 Hz,once a day.The needle was retained for 20 minutes each time,and a total of 4 courses of treatment were conducted,with 6 days per course.The rabbits in the atorvastatin group were administered atorvastatin calcium tablet suspension(1 mg/kg)orally once a day,for 6 days per course,with a total of 4 courses.After the interventions,HE staining was performed to observe the morphological changes in the common carotid artery tissue of the rabbits.Peritoneal macrophages were collected from the rabbits,and the mRNA expression levels of ABCA1,ABCG1,and SR-B Ⅰ were measured using real-time fluorescence PCR.The protein expression levels of ABCA1,ABCG1,and SR-B Ⅰ were detected using Western blotting.Results The negative control group exhibited smooth intima of common carotid artery in rabbits,while the model group displayed damaged intima of common carotid artery,thickened artery walls,and the formation of atherosclerotic plaques.The electroacupuncture group and atorvastatin group showed significant improvements in wall thickening and a reduction in plaque area.Compared with the negative control group,the mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits in the model group were reduced(P＜0.01).Compared with the model group,the electroacupuncture group and atorvastatin group exhibited increased mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in abdominal macrophages of rabbits(P＜0.01).Furthermore,the atorvastatin group demonstrated increased mRNA levels of ABCG1 and SR-B Ⅰ,as well as increased protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits,in comparison to the electroacupuncture group(P＜0.01).Conclusion Electroacupuncture can enhance the expressions of ABCA1,ABCG1,and SR-B Ⅰ mRNA and protein in abdominal macrophages of AS rabbits,thereby promoting the process of cholesterol reverse transport.This may be one of the mechanisms underlying the effectiveness of acupuncture in the treatment of AS.
