Abstract:
Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Method Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg ） by Gavage, and the positive control drug atorvastatin calcium （1.5 mg/kg）. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Result The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups （middle dose 0.55±0.21 mM, high dose 0.52±0.22 mM v.s. 0.81±0.29 mM in model group P<0.01）. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by atorvastatin calcium. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in atorvastatin calcium group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduces the body weight of animals with high fat, reduce liver size, fat deposition, inflammatory damage and also significantly reduces blood lipid CHOL and LDL-C levels and reduce transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

Abstract:
At present, the management of sepsis remains largely non-specific, highlighting an urgent need for novel therapeutic strategies. Stem cells have garnered significant attention in the treatment of various diseases due to their unique biological properties. Stem cells enhance sepsis survival through mechanisms such as reducing bacterial burden, modulating inflammation, and ameliorating organ dysfunction. Recent studies have shown that stem cells can increase the survival rate of sepsis patients through multiple pathways such as reducing the bacterial load of the host, regulating inflammatory homeostasis, and improving multi-organ dysfunction. Their derivatives, exosomes, can also alleviate the imbalanced immune response in sepsis patients. most recent advances in stem cell-based therapies for sepsis were summarized in this paper.

Abstract:
Objective To construct glucose oxidase–loaded nanogels （GONGs）, optimize their formulation, and evaluate their capacity to inhibit the Warburg effect in glioma cells. Methods A responsive polymer （HAM） was synthesized and used to self-assemble GONGs, which were then characterized. Encapsulation efficiency and drug loading were determined using fluorescence spectrophotometry. Biocompatibility was tested by measuring cytotoxicity and hemolytic activity. Western blotting was used to evaluate the effects of GONGs on the expression of proteins associated with the Warburg phenotype and oxidative damage in glioma cells. Results GONGs prepared at a drug-to-polymer ratio of 1∶10 exhibited a particle size of 140.3 nm and a zeta potential of −27.2 mV. Compared with free GOx, GONGs markedly reduced cytotoxicity, increasing the IC50 in hUVEC cells from 2.150 nmol/L to 74.86 nmol/L, and significantly decreased hemolysis. At a GOx concentration of 2 nmol/L, GONGs effectively downregulated glycolysis-related proteins, such as HK2 and LDHA, and inhibited glutamine metabolism in glioma cells. Conclusion GONGs exhibited high GOx loading capacity, significantly reduced GOx-induced cytotoxicity, inhibited the Warburg effect in glioma cells and induced oxidative damage.

Abstract:
Sodium-glucose cotransporter 2 （SGLT2） is involved in most glucose reabsorption in the kidney. Inhibition of SGLT2 leads to the excretion of glucose through urine and represents a new concept in the treatment of type 2 diabetes. With the development of pharmacogenomics, it was found that SGLT2 gene polymorphism had certain effects on fasting blood glucose, glycosylated hemoglobin and insulin levels, and may affect the risk of type 2 diabetes and response to treatment with SGLT2 inhibitors, which is of great significance in the treatment of T2DM. Domestic and international studies on SGLT2 gene polymorphism were reviewed and their effects on SGLT2 inhibitor （SGLT2i） in the treatment of T2DM were discussed in this paper.

Abstract:
Objective To explore the application effect of a standardized management method based on Failure Mode and Effect Analysis （FMEA） in optimizing the whole-process quality control system of the Intravenous Admixture Service （PIVAS）. Methods The quality control management system of the IVAS was optimized by establishing six quality control groups led by the head nurse, with full participation of pharmacy, nursing, and logistical staff, ensuring comprehensive coverage and traceability of all quality control links. Each group conducted Risk Priority Number （RPN） scoring for potential failure modes in their respective quality control processes, and targeted improvement measures were formulated based on the scoring results. The RPN values of failure modes and quality control-related evaluation indicators before and after implementation were compared to achieve closed-loop management. Results After one year of management, the RPN values of the six major failure modes significantly decreased compared to those before implementation （P<0.05）. The compounding error rate dropped to 0.13%, the dispensing error rate decreased to 0.95%, the compounding efficiency increased to 98%, the delivery time was shortened by 0.45 hours per batch, the intervention rate for irrational prescriptions rose to 94.87%, satisfaction improved to 96.78%, and the participation rate of quality control personnel reached 95.36% （P<0.05）. Conclusion FMEA-based identification of potential failure modes in the whole-process quality control system of the IVAS, combined with risk quantification and targeted interventions, significantly reduces high-risk failure modes, improves compounding accuracy and efficiency, and ensures the safety of clinical intravenous medication and the effectiveness of healthcare quality management.

Abstract:
Objective To clarify the current development status and research hotspots in the field of experimental drug management in China through data mining by bibliometric. Methods Key words such as “experiment”, “drug”, and “management” were used the search the Chinese literature in China National Knowledge Infrastructure （CNKI）. The title, author name, author affiliation, Chinese abstract, Chinese keywords, publication period, journal name, and other content of the literature were extracted from the literature. Cluster analysis was performed by CNKI literature visualization analysis system, CiteSpace and other software, and a network knowledge map was drawn. Results The literature in the field of experimental drug management in China was first published in 1994, and a total of 140 articles were published until 2022. Among them, 20 articles were supported by relevant funds, and the keyword co-occurrence frequency was highest among “subjects”. The most frequently published medium was the Chinese Pharmacological Yearbook. Conclusion At present, the quantity and quality of literature in the field of experimental drug management in China are relatively small, and the cooperation and communication among authors are not close. The funding from various fund projects in this field is also lacking. These factors lead to a lower overall development level and slower development speed in this field.

Abstract:
Objective To compare the cost-effectiveness between valproate and levetiracetam in the treatment of childhood epilepsy and provide an economic basis for clinical medication choices. Methods A cost-effectiveness analysis was conducted using a decision tree model to compare the effectiveness and drug costs of valproate and levetiracetam in treating childhood epilepsy. Single-factor sensitivity analysis and probabilistic sensitivity analysis were used to assess the impact of parameter variations on the study results. Results The treatment cost of levetiracetam was significantly higher than that of sodium valproate. The incremental cost-effectiveness ratio （ICER） of levetiracetam compared to sodium valproate was ¥8 628.43. Sensitivity analysis results were consistent with the base-case analysis. The probabilistic sensitivity analysis showed that, over a 6-month treatment period, levetiracetam became a more cost-effective option when the willingness-to-pay （WTP） threshold was ¥9,000 or higher. One-way sensitivity analysis revealed that the price of levetiracetam was the most influential factor affecting the ICER. Conclusion When the WTP per effective pediatric epilepsy case is ¥9,000 or higher, levetiracetam demonstrates a cost-effectiveness advantage.

Abstract:
Objective To investigate the effect of activating α7 nicotinic acetylcholine receptor （α7nAChR） on calcium chloride （CaCl2）-induced abdominal aortic aneurysm （AAA） injury in mice. Methods AAA model was induced by CaCl2 in wild type （WT） mice and α7nAChR knockout （α7nAChR−/-） mice. The effects of knockout of α7nAChR on histological damage in CaCl2-induced AAA mice and expression of inflammatory factors were assessed by HE staining, EVG staining and IHC staining. Rat-derived primary vascular smooth muscle cells （VSMC） were stimulated with TNF-α, which mimicked the inflammatory environment of AAA. The expressions of inflammation-related proteins were detected by using Western-Blot with or without PNU-282987 to activate α7nAChR. Results Aortic dilatation was obvious, and the aortic structure was disrupted in CaCl2-induced AAA mice. Knockout of α7nAChR further exacerbated the histological injury and significantly up-regulated the expression of inflammation-related proteins in aorta of AAA mice. It was showed that TNF-α stimulation of VSMC increased inflammation-related protein expression, whereas activation of α7nAChR prevented the phenomenon. Conclusion Activation of α7nAChR could attenuate CaCl2-induced AAA injury in mice by suppressing the inflammatory response.

Abstract:
Oxidative stress is an important pathophysiological pathway for the development and progression of ferroptosis. Under pathological conditions, the production of a large amount of reactive oxygen species（ROS）exceeds the buffering capacity of the antioxidant defense system, resulting in lipid peroxidation and cell ferroptosis in the state of oxidative stress. Cellular lipid peroxidation can generate toxic aldehydes, which interact with important biological macromolecules and break the normal function of cells. At present, it has been found that aldehyde dehydrogenase 2（ALDH2）can eliminate these aldehydes and regulate the cycle of toxic aldehydes-ROS-oxidative stress-lipid peroxidation, thereby improving the prognosis of diseases associated with iron death. Ferroptosis and ALDH2 were introduced, and the current researches on ALDH2 were summarized to improve diseases associated with iron death, which can open up new directions for the subsequent research on the treatment of diseases associated with iron death.

Abstract:
Objective To provide a reference for the establishment, development and application of the adverse drug reaction （ADR） automated monitoring system, through verifying and quantifying the research hotspots and advantages of the system by CiteSpace software and systematic review. Methods Literature on ADR automated monitoring up to December 2023 were retrieved and screened from CNKI and web of science databases. CiteSpace 6.4.R1 software was used to conduct co-occurrence, clustering and emergence analysis, and to visualize and comparatively analyze the research hotspots, rules and distribution in the field of automated monitoring of ADR at home and abroad. In compliance with the preferred reporting items for systematic reviews and Meta-analyses （PRISMA）, literature covering publications in English and Chinese including detection rates of ADRs collected using Incident Reporting Systems （IRSs） and/or automated monitoring systems were retrieved and screened. The advantages and disadvantages of automated monitoring systems were analyzed by comparing the differences between these two systems in terms of the number of ADR reports and the types of positive signals. Results A total of 56 articles in English and 80 articles in Chinese were indexed by CiteSpace. The research hotspots in recent years included data mining, deep learning, text classification techniques, machine learning and so on. A total of seven studies compiled with the inclusion criteria for the systematic evaluation, all of which were completed between 1991 and 2021 in hospitals in four countries. 150 526 medical records were reviewed from 15 institutions. A total of 194 ADR reports were collected by IRSs. A total of 2 090 ADR reports were collected by the automated monitoring system over the same period, indicating a 977% increase in the number of ADR reports （P=0.0156 ） compared with the IRSs. Conclusion The ADR automatic monitoring system had significantly improved the level of drug risk identification and reduced costs, but it was necessary to optimize the algorithm, expand the data source and carry out standardization construction to overcome the current limitations.

Abstract:
This study aimed to clarify the causal relationship between meaning in life and depression symptoms, explore the evolutionary patterns of meaning in life, and assess its impact on the incidence of depressive symptoms. A two-wave longitudinal study with a 12-month interval was conducted among 896 university students recruited from one university. The meaning in life questionnaire and the depression symptom screening questionnaire were administered. The findings showed that: 1）Meaning in life at T1 negatively predicted depression symptoms at T2. Conversely, depression symptoms at T1 did not significantly predict meaning in life at T2. 2）The evolutionary patterns of meaning in life from T1 to T2 could be categorized into four groups: sustained low meaning, meaning improvement, meaning reduction, and sustained high meaning. The incidence of depressive symptoms in these four groups was 13.00%, 5.00%, 12.00%, and 4.00%, respectively. 3）The evolutionary patterns of meaning in life significantly impacted the incidence of depressive symptoms. Compared to the sustained high meaning group, both the sustained low meaning group and the meaning reduction group exhibited significantly higher rates of depression symptoms. The results suggest that psychological health education in universities should focus on individuals with sustained low meaning or meaning reduction, and that enhancing meaning in life serves as an effective intervention approach to reducing the incidence of depression symptoms among university students.

Objective To determine the content of five alkaloids from extracts of piper longum and test the pharmacodynamic effect of them on rats with experimental myocardial ischemia induced by injection of pituitrin. Methods The content of five alkaloids was determined simultaneously by HPLC. The experimental myocardial ischemia in rats was induced by injection of pituitrin, and the absolute value of T wave change and change of heart rate before and after model establishment were chosen to be the observation index. The effects of large, medium and small dose groups were evaluated. Results Three batches of samples were analyzed, with the contents of piperine for 56.1%, 49.7%, 51.6%; N-isobutyl-(2E,4E)octadecatrienamide for 4.5%, 4.2%, 4.3%; guineensine for 0.46%, 0.38%, 0.40%; piplartine for 1.73%, 1.67%, 1.70% and piperamide for 0.55%, 0.46%, 0.49%, respectively. All dose groups from extracts of piper longum had significantly reduced the absolute value of T wave and almost have no effect on the change of heart rate, except the high dose group showed the effect of reducing heart rate at some time . Conclusion The HPLC method was suitable for the simultaneous determination of five alkaloids from extracts of piper longum. It was shown that extracts of piper longum had good bioactivity in anti-myocardial ischemia.

Abstract:
Objective To investigate the efficacy and safety of EGFR-TKIs monotherapy and its combination therapy in the first-line treatment of advanced non-small cell lung cancer（NSCLC）patients with EGFR mutations. Methods Databases such as PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were systematically searched to collect eligible phase II/III randomized controlled trials （RCTs）, with the time range from the establishment of the databases to June 2023. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in the studies. Outcome data, including overall survival （OS）, progression-free survival （PFS）, objective response rate （ORR）, grade 3 or higher adverse events （≥3 AEs）, and serious adverse events （SAEs）, were collected. A network meta-analysis was performed using R software （version 4.2.1） under the Bayesian theoretical framework. Subgroup analyses of survival outcomes （OS, PFS） were conducted based on different clinical and pathophysiological characteristics of the patients. Results A total of t wenty-eight phase II/III RCTs were included in the study, involving a total of 7 460 patients and 18 first-line treatment regimens. The results showed that in terms of efficacy, gefitinib + pemetrexed-containing chemotherapy performed best in OS and ORR, while osimertinib + bevacizumab performed best in PFS. In terms of safety, furmonertinib had the lowest incidence of ≥3 grade AEs, and osimertinib had the lowest incidence of SAEs. Subgroup analysis results indicated that the efficacy and safety of various treatment regimens differed among patients with different clinical and pathological characteristics. Conclusion Monotherapy with third-generation EGFR-TKIs, represented by osimertinib, serves as the preferred therapeutic option considering both efficacy and safety profiles. While some combination therapies can enhance survival benefits, but need to be vigilant about increased toxicity. Clinical decision-making should be tailored based on patient' mutation subtypes, comorbidities, and tolerance.

Abstract:
Objective To explore the molecular mechanism of Jianfu mixture in the treatment of erectile dysfunction （ED） by using network pharmacology and molecular docking techniques, and to validate its core targets and mechanisms through in vitro experiments. Methods The active components and corresponding molecular targets of Jianfu mixture were searched by searching TCMSP and Batman-TCM databases, and searching the disease targets of ED by using GeneCards database. Find the intersection of drug ingredient target and disease target. The interaction between intersected targets was described and analyzed by String database, and the analysis results were visualized by Cytoscape software to determine the core target and the corresponding active components. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed for intersection targets; the core target within the intersection were found through MCODE plug-in on Cytoscape software and molecular docking was performed with the corresponding active ingredients. An endothelial dysfunction model was established by transfecting HUVECs with si-eNOS. Intervene with different concentrations of the Jianfu mixture for the model cells for 24 hours. QPCR was used to detect mRNA expression of core targets （MAPK1, MAPK3, JUN, ESR1, MAPK8）; Western blot was used to analyze protein expression （eNOS, JUN, p-JUN, MAPK, p-MAPK） and phosphorylation levels. Results 144 effective active components and 168 active components target-disease targe intersection of Jianfu mixture were obtained. GO analysis revealed 2005 biological processes, 151 molecular functions, and 63 cellular components. KEGG analysis yielded 181 pathways. 5 core targets including MAPK1, MAPK3, JUN, ESR1 and MAPK8 were screened out. The active components such as β-sitosterol, kaempferol, astapterocarpan had good binding affinity with the core target. In vitro experiments confirmed successful construction of the endothelial dysfunction model （eNOS expression significantly decreased after si-eNOS transfection）. Jianfu mixture dose-dependently inhibited mRNA expression of MAPK1, MAPK3, JUN, ESR1, and MAPK8. Additionally, it reduced phosphorylation levels of JUN and MAPK, indicating inhibition of the JNK/c-Jun and ERK/MAPK signaling pathways to improve endothelial function. Conclusion Jianfu mixture treats ED by suppressing abnormal activation of multi-target signaling pathways （MAPK/JUN/ESR1）, reducing endothelial apoptosis, and promoting NO synthesis. This mechanism aligns with the traditional Chinese medicine principle of “activating blood circulation, resolving stasis, tonifying Qi, and strengthening cardiovascular function.” The study provides molecular-level evidence for the therapeutic efficacy of Jianfu mixture in ED management.

Abstract:
Traditional Chinese medicine contains a variety of volatile components（VOCs）such as terpenes and aliphatics, which have significant pharmacological activities, and are commonly analyzed by gas chromatography（GC）and gas chromatography-mass spectrometry（GC-MS）. Although the separation ability is strong, the samples need to be pre-treated and the analysis time is long. In recent years, the combination of gas chromatography（GC）and ion migration spectrometry（IMS）has been widely used in the academic community. The combination of high separation ability of GC and rapid reaction ability of IMS has the advantages of no sample pretreatment, fast analysis time, low detection limit and simple operation. It is increasingly widely used in traditional Chinese medicine research. This review introduces the working principle of GC-IMS, summarizes its application in VOCs research of traditional Chinese medicine, and looks forward to the future development direction.

The combination of high separation ability of GC and rapid reaction ability of IMS has the advantages of no sample pretreatment, fast analysis time, low detection limit and simple operation. It is increasingly widely used in traditional Chinese medicine research. This review introduces the working principle of GC-IMS, summarizes its application in VOCs research of traditional Chinese medicine, and looks forward to the future development direction.

Abstract:
Perilla is an annual herbaceous plant with edible and medicinal value belonging to the Lamiaceae family. It has a long history of cultivation and use. The volatile oil is one of its main active components in perilla leaves, and Perilla aldehyde is its characteristic component. The methods for determining the content of volatile oil are diverse and affected by genetic differences, growth period, and extraction methods. It is mainly synthesized and regulated through the mevalonic acid pathway and shikimic acid pathway, and has biological activities such as antibacterial, antioxidant, anti-inflammatory, anti-tumor, and anti-depressant. The characteristics of perilla volatile oil make it have broad application prospects in food preservation, fragrance industry, and medicine. With further research on the components and biosynthesis pathways of perilla volatile oil, it is important to improve the quality of perilla and further clarify the active substance basis and mechanism of action of volatile oil, and its medicinal and edible value will be further explored and utilized.

Abstract:
Objective To compare the effecacy of colistin sulphate with cefoperazone and sulbactam in the treatment of pan-resistant Acinetobacter baumannii with the combination therapy of tigecycline with cefoperazone and baubactam. Methods By retrospective analysis, 216 ICU patients with pneumonia diagnosed with Acinetobacter baumannii from January 2019 to July 2021 was propensity matching divided into a test group （71） and a control group （145） by 1∶2. The test group was treated with colistin sulfate combined with cefoperazone and sulbactam, control group was treated with tigecycline combined with cefoperazone and sulbactam. According to the changes of clinical symptoms and indicators before and after treatment in the two groups, the clinical response rate, bacterial clearance rate and 28-day mortality rate of the two groups were observed. Results The clinical response and bacterial clearance of the test group were higher than that of the control group （P <0.05）; At the end of treatment, the clinical response rate and 28-day mortality were not statistically significant. Conclusion Colistin sulfate combined with cefoperazone and sulbactam was comparable to its efficacy and was superior to tigecycline combined with cefoperazone and sulbactam group in early assessment of clinical efficacy and bacterial clearance.

Abstract:
Objective To investigate the preventive and therapeutic effects of ethanol extracts derived from three sources of traditional Chinese medicine: Stellera chamaejasme L., Euphorbia fischeriana Steud., and Euphorbia kansuensis Prokh., on imiquimod （IMQ）-induced psoriasis in mice. Methods Thirty-six male BALB/c mice were randomly divided into the following 6 groups with 6 mice in each group: blank control, model, Stellera chamaejasme, Euphorbia fischeriana, Euphorbia kansuensis, and calcipotriol. PASI （Psoriasis Area and Severity Index） scores were used to record the changes of skin lesions in each group; HE （hematoxylin-eosin） staining was used to observe the pathological morphology of skin and measure the thickness of the epidermis. Immunohistochemistry was used to detect the expression of nuclear antigen Ki67 in the skin tissues of mice. Results Compared with the model group, the three kinds of ethanol extracts can reduce the PASI score, inhibit epidermal thickening, and decrease expression of Ki67 in the psoriasis mice. Among them, the therapeutic effect of Stellera chamaejasme was the most significant and it was better than the commonly used topical drug calcipotriol. Conclusion The ethanol extract of Stellera chamaejasme has good anti-psoriatic activity, can inhibit the abnormal proliferation of keratinocytes, can reduce the expression of Ki67, and can significantly improve psoriasis-like skin lesions.
