ObjectiveTo study the mechanism of Huanglian Jiedutang (HLJDT) in treating mice with atherosclerosis (AS) by improving ferroptosis. MethodsA total of 10 SPF C57BL/6J mice were selected as a normal group, and 50 ApoE-/- mice were randomly divided into five groups: model group, low-dose group of HLJDT, medium-dose group of HLJDT, high-dose group of HLJDT, and atorvastatin (ATV) group. ApoE-/- mice were fed a high-fat diet for eight weeks to establish the AS model, and at the 9th week, they were given normal saline, low, medium, and high doses of HLJDT (3.9, 7.8, 15.6 g·kg-1·d-1), and atorvastatin calcium tablets (0.01 g·kg-1·d-1), respectively, for a total of eight weeks. The formation of aortic plaque in mice was observed by gross oil red O staining and Masson staining. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) in blood fat were measured by the automatic biochemical analyzer, and the mitochondrial structure of the aorta was observed by transmission electron microscopy. The content of serum superoxide dismutase (SOD) in serum was detected by enzyme-linked immunosorbent assay (ELISA). The content of reduced glutathione (GSH) in serum was detected by the microplate method, and that of malondialdehyde (MDA) in serum was detected by the TBA method. The protein expression of nuclear factor E2-associated factor 2 (Nrf2)/glutathione peroxidase 4 (GPX4) signaling pathway was detected by Western blot. ResultsCompared with those of the normal group, the contents of TC, LDL-C, TG, HDL-C, and MDA in the serum and the aortic vascular plaque deposition of the model group were significantly increased (P<0.01), while the expression levels of SOD and GSH in serum, as well as Nrf2, solute carrier family 7 member 11 (SLC7A11), and GPX4 in aorta were significantly decreased (P<0.01). Mice in the model group appeared mitochondrial fragmentation and vacuolation in the aorta, volume atrophy, mitochondrial crista reduction, or a loose and disorganized form. Compared with those in the model group, the aortic vascular plaque deposition was significantly decreased in the low-dose, medium-dose, and high-dose groups of HLJDT and ATV group, and the contents of serum TC, LDL-C, TG, and MDA in serum were significantly decreased (P<0.05, P<0.01). The contents of serum SOD and GSH and the expression levels of Nrf2, SLC7A11, and GPX4 in the aorta were increased (P<0.05, P<0.01), and the symptoms of aortic mitochondrial vacuolation were alleviated. The number of cristae was increased, and they were ordered neatly. ConclusionHLJDT can reduce aortic vascular plaque deposition, decrease blood lipid and MDA expression, increase SOD and GSH expression, and ameliorate the pathological changes of ferroptosis, the mechanism of which is related to the Nrf2/GPX4 signaling pathway.

OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance (shorted for “medical alliance”) of Wanzhou District of Chongqing, and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units (5 leading units and 16 member units) of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use, pharmaceutical personnel team construction, the development of pharmaceutical care, and rational use of antibiotics. RESULTS Among the 21 constituent units, 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties, with a total compliance rate of 85.71%; 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount, with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively, and the proportions of personnel with senior professional titles were 8.56% and 1.63%, respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units, and 5 clinical pharmacy information service platforms were established; all 5 leading units were able to regularly carry out clinical pharmacy projects, while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units (4.81%, 5.21%) were significantly higher than those of the 5 leading units (2.80%, 4.00%). CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However, the data on the allocation of pharmaceutical professionals and the number, qualifications, and job titles of clinical pharmacists in member units are generally low. Moreover, the pharmaceutical service projects and service quality in member units need to be further improved.

ObjectiveBy comparing the composition and content of volatile components in raw products, wine-washed products and wine-fried products of Ligusticum sinense cv. Chaxiong rhizome(LSCR), to investigate the influence of wine processing on the volatile components of LSCR, in order to provide a basis for the development of quality standards for LSCR and its processed products. MethodsElectronic nose was used to identify the odors of LSCR, wine-washed and wine-fried LSCR, and their volatile components were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the relative mass fractions of these components were determined by peak area normalization method. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the obtained sample data by SIMCA 14.1 software, and the differential components of LSCR, wine-washed and wine-fried LSCR were screened according to the variable importance in the projection(VIP) value>1. Pearson correlation analysis was used to explore the relationship between volatile differential flavor components and electronic nose sensors. ResultsElectronic nose detection results showed that there were significant differences in the odors of LSCR, wine-washed and wine-fried LSCR, mainly reflected in the sensors S2, S4, S5, S6, S11, S12, S13. And a total of 62 compounds were identified from LSCR and its wine-processed products, among which 46, 50 and 51 compounds were identified from LSCR, wine-fried and wine-washed LSCR, respectively. There were 21 differential components between the raw products and wine-fried products, of which 10 components were increased and 11 were decreased after processing. There were 20 differential components between the raw products and wine-washed products, of which 11 constituents increased and 9 decreased after processing. There were 17 differential components between the wine-wash products and wine-fried products. Compared with the wine-washed products, the contents of 13 components in the wine-fried products increased, and the contents of 4 components decreased. The increasing trend of the content of phthalides in the wine-washed products was more obvious than that in the wine-fried products, but the content of total volatile components was higher in the wine-fried products than the wine-washed products. Correlation analysis showed that there were different degrees of correlation between the 7 differential sensors of electronic nose and 24 differential volatile components, mainly phthalides and olefins. ConclusionThe odor and the content of volatile components in LSCR changed obviously after wine processing, and n-butylphthalide, Z-butylidenephthalide and E-ligustilide can be used as the candidate differential markers of volatile components in LSCR before and after wine processing.

Objective To analyze the application effects of artificial intelligence (AI) software and Mimics software in preoperative three-dimensional (3D) reconstruction for thoracoscopic anatomical pulmonary segmentectomy. Methods A retrospective analysis was conducted on patients who underwent thoracoscopic pulmonary segmentectomy at the Second People's Hospital of Huai'an from October 2019 to March 2024. Patients who underwent AI 3D reconstruction were included in the AI group, those who underwent Mimics 3D reconstruction were included in the Mimics group, and those who did not undergo 3D reconstruction were included in the control group. Perioperative related indicators of each group were compared. Results A total of 168 patients were included, including 73 males and 95 females, aged 25-81 (61.61±10.55) years. There were 79 patients in the AI group, 53 patients in the Mimics group, and 36 patients in the control group. There were no statistical differences in gender, age, smoking history, nodule size, number of lymph node dissection groups, postoperative pathological results, or postoperative complications among the three groups (P>0.05). There were statistical differences in operation time (P<0.001), extubation time (P<0.001), drainage volume (P<0.001), bleeding volume (P<0.001), and postoperative hospital stay (P=0.001) among the three groups. There were no statistical differences in operation time, extubation time, bleeding volume, or postoperative hospital stay between the AI group and the Mimics group (P>0.05). There was no statistical difference in drainage volume between the AI group and the control group (P=0.494), while there were statistical differences in operation time, drainage tube retention time, bleeding volume, and postoperative hospital stay (P<0.05). Conclusion For patients requiring thoracoscopic anatomical pulmonary segmentectomy, preoperative 3D reconstruction and preoperative planning based on 3D images can shorten the operation time, postoperative extubation time and hospital stay, and reduce intraoperative bleeding and postoperative drainage volume compared with reading CT images only. The use of AI software for 3D reconstruction is not inferior to Mimics manual 3D reconstruction in terms of surgical guidance and postoperative recovery, which can reduce the workload of clinicians and is worth promoting.
7.Effects of probiotic treatment on the prognosis of patients with sepsis: a systematic review
World Journal of Emergency Medicine 2025;16(1):18-27
BACKGROUND Sepsis, a common acute and critical disease, leads to 11 million deaths annually worldwide. Probiotics are living microorganisms that are beneficial to the host and may benefit sepsis outcomes, but their effects are still inconclusive. This study aimed to evaluate the overall effect of probiotics on the prognosis of patients with sepsis.
DATA RESOURCES: We searched several sources for published/presented studies, including PubMed, EMBASE, Web of Science, the Cochrane Library and the US National Library of Medicine Clinical Trials Register (www.clinicaltrials.gov) updated through July 30, 2023, to identify all relevant randomized controlled trials (RCTs) or observational studies that assessed the effectiveness of probiotics or synbiotics in patients with sepsis and reported mortality. We focused primarily on mortality during the study period and analyzed secondary outcomes, including 28-day mortality, in-intensive care unit (ICU) mortality and other outcomes.
RESULTS: Data from 405 patients in five RCTs and 108 patients in one cohort study were included in the analysis. The overall quality of the studies was satisfactory, but clinical heterogeneity existed. All adult studies reported a tendency for probiotics to reduce the mortality of patients with sepsis, and most studies reported a decreasing trend in the incidence of infectious complications, length of ICU stay and duration of antibiotic use. There was only one RCT involving children.
CONCLUSION: Probiotics show promise for improving the prognosis of patients with sepsis, including reducing mortality and the incidence of infectious complications, particularly in adult patients. Despite the limited number of studies, especially in children, these findings will be encouraging for clinical practice in the treatment of sepsis and suggest that gut microbiota-targeted therapy may improve the prognosis of patients with sepsis.

Objective To determine the risk factors related to the occurrence of colorectal adenomatous polyps and provide a basis for early screening, diagnosis, and treatment of colorectal cancer. Methods A total of 1 527 cases of colorectal polyps detected by colonoscopy were selected as the research subjects. Data on sociodemographic information, lifestyle and dietary habits, clinical history, laboratory tests, and endoscopic characteristics were collected. The patients were divided into adenoma and non-adenoma groups based on the pathological type. Multivariate logistic regression analysis was conducted to explore the influence of the above factors on the occurrence of colorectal adenoma. Results Old age (OR: 1.024, 95%CI: 1.001-1.048, P=0.044), high body mass index (OR: 1.046, 95%CI: 1.008-1.087, P=0.020), and a history of smoking (OR: 1.493, 95%CI: 1.035-2.158, P=0.032) were independent risk factors for the occurrence of colorectal adenoma. Patients with better cognitive function had a lower risk of developing colorectal adenoma than those with poorer cognitive function (OR: 0.929, 95%CI: 0.871-0.984, P=0.017). Polyps located in the rectum (OR: 0.396, 95%CI: 0.229-0.677, P=0.001) and those of flat type (OR: 0.531, 95%CI: 0.342-0.810, P=0.004) or laterally spreading type (OR: 0.306, 95%CI:

[Objective] To explore the effects of different methods on antibody detection through investigating the causes of cross-matching incompatible in a patient with gastric malignant tumor, and to establish flow cytometry protocol for confirming hemolytic transfusion reaction (HTR). [Methods] Antibodies in the patient's serum were identified by red blood cells (RBCs) blood grouping, antibody screening and identification, acid elution test and PEG enhancement test. To confirm HTR, patient RBCs, proximal and distal ends RBCs, separated by capillary centrifugation, were tested by direct antiglobulin test (DAT) and Jka antigen single label and double label flow cytometry. [Results] Routine serological technology revealed the presence of anti-C, e (titer:2) and anti-Jka (titer >1) in the patient’s serum. After separation using capillary centrifugation technology, both the proximal and distal DAT and Jka antigen tests were negative. Both DAT and Jka antigen positive red blood cells (0.21%, 6/6 327) were found in the patient's blood samples by flow cytometry. After separation of blood samples by capillary centrifugation, there were significantly more DAT and Jka antigen double-positive RBCs in the distal end (0.43%, 33/7 707) than in the proximal end (0.09%, 15/7 225). Two blood samples were screened from over 100 donor blood samples that are compatible with the patient's cross-matching, and the transfusion effect was favorable. [Conclusion] Serological methods combined with flow cytometry could improve the sensitivity of antibody detection, provide a more accurate basis for the diagnosis of HTRs, and guarantee the safety of blood transfusion.

Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint, the mechanism of which is closely related to signaling pathways, such as osteoprotegerin (OPG)/receptor activator of nuclear factor-κB (RANK)/RANK ligand, mitogen-activated protein kinase (MAPK), Wnt/β-catenin (β-catenin), phosphoinositide 3- kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR). Traditional Chinese medicine has the characteristics of multiple components and targets, and is widely used for the treatment of autoimmune diseases due to its low toxicity, strong specificity, and high efficacy. This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways, regulating immune inflammatory responses, and inhibiting biological processes such as bone destruction, ectopic osteogenic differentiation, cell apoptosis, and autophagy.
