ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus(GF) before and after being charred, providing data support for research on the material basis of GF Carbonisata(GFC). MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Orbitrap MS/MS) was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then, principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection(VIP) value>1, differential secondary and primary metabolites before and after carbonization were screened. In addition, MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG), so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified, including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories, primarily including iridoid glycosides, flavonoids, and terpenoids, their fragmentation pathways were also analyzed. Simultaneously, multivariate statistical analysis was performed on the secondary and primary metabolites, identifying 70 and 59 differential metabolites, respectively. The secondary metabolites were enriched in two metabolic pathways, including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis, while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization, with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide, crocin Ⅱ, crocetin, and jasminoside B. while the contents of 4-hydroxycoumarin, geniposidic acid, gentiopicroside, and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

Onco-critical care has emerged as an important subspecialty at the intersection of critical care medicine and oncology, attracting increasing attention in recent years. With continuous innovations in cancer therapies, patient survival has improved significantly; however, the incidence of associated critical complications has also increased. The reasons for cancer patients requiring intensive care unit admission are diverse and can be broadly categorized into three groups: progression of the underlying malignancy, treatment-related complications, and coexisting classical critical illnesses. Traditional critical care concepts and practices face limitations in addressing the multidimensional and heterogeneous challenges of onco-critical care. Based on the core mechanism of critical illness development—host/organ unregulated response (HOUR)—this article systematically elaborates on how this framework advances understanding and clinical practice into onco-critical care, with emphasis on its manifestations in neuroendocrine, immune-inflammatory, and coagulation-metabolic pathways. The review summarizes recent advances in clinical assessment and phenotyping systems for onco-critical illness and discusses a multidisciplinary, integrated management strategy centered on the "Disease Control, Host Response Modulation, Organ Support" triad. Finally, major challenges and future directions in this field are outlined. By integrating existing evidence and theoretical insights, this review aims to provide new perspectives and a theoretical foundation for the clinical management of onco-critical illness, thereby promoting its evolution toward precision and standardization.

OBJECTIVE To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules. METHODS Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography (HPLC) fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition). The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile, the contents of neochlorogenic acid (NGA), chlorogenic acid (CHA), cryptochlorogenic acid (CGA), forsythoside A (FTA), 3,5-O-dicaffeoylquinic acid (3,5-O- DA), 4,5-O-dicaffeoylquinic acid (4,5-O-DA), and angoroside C (AGC) in the samples were determined by HPLC. RESULTS The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples, and 7 of them were identified [NGA (peak 2), CHA (peak 3), CGA (peak 5), FTA (peak 11), 3,5-O-DA (peak 12), 4,5-O-DA (peak 13), and AGC (peak 14)]; the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories; the results of OPLS-DA indicated that peak 4 (unknown), peak 11 (FTA), peak 8 (unknown), peak 9 (unknown), and peak 1 (unknown) were the differential components. The content ranges of NGA, CHA, CGA, 3,5-O-DA, FTA, 4,5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7, 0.269 1-0.506 3, 0.228 1-0.461 1, 0.443 9-1.044 6, 0.066 7-0.155 7, 0.062 8-0.143 8, and 0.057 4-0.105 7 mg/g, respectively. CONCLUSIONS The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable, and can be used for the quality evaluation of Qingwen hufei granules.

OBJECTIVE To establish a Chinese drug-related problem (DRP) classification system applicable to pharmacist-led pharmaceutical care in China, providing pharmacists with an effective and practical tool for pharmaceutical care. METHODS A multi-stage process was employed to construct the DRP classification system, including literature review and analysis, comparison of existing classification systems, refinement of classification items and framework development, two rounds of standard case validation, expert discussion, and system revision. The Fleiss′ kappa test was used to calculate the consistency coefficient κ, assessing the reliability of pharmacists participating in evaluating the classification system. An electronic questionnaire comprising six items was employed to evaluate the system’s applicability. RESULTS The constructed Chinese DRP classification system comprised six sections [problem(including potential problems), DRP evaluation, cause (including possible causes of potential problems), intervention, acceptance of intervention and DRP status], with 24 primary codes and 96 secondary codes. In the first round of case validation, κ values exceeded 0.4 for all sections except “intervention” and “DRP status”. In the second round, κ values exceeded 0.4 for all sections. In the applicability evaluation of the classification system, positive ratings (“strongly agree” or “agree”) exceeded 85% for all items. Specifically, positive ratings for“the classification system can provide appropriate category selection”,“ the classification system is comprehensive”,“ the classification system is convenient to use” and “the classification system is highly satisfactory” exceeded 92%. CONCLUSIONS The Chinese DRP classification system developed demonstrates both high reliability and applicability, providing an effective and practical classification tool for pharmacists in China to conduct pharmaceutical care.

Objective To explore the prevalence of Helicobacter pylori (Hp) infection and its association with dietary and lifestyle habits among the adult physical examination population in Xuzhou area. Methods Retrospectively selected the physical examination population who underwent HP testing at our hospital's physical examination center from May 2021 to December 2023 as the research object. The prevalence of Hp infection in the population was analyzed based on the physical examination results. A questionnaire survey was used to collect information on the eating and living habits of all study subjects. Logistic regression was used to analyze the relationship between eating and living habits and Hp infection. Results A total of 1 354 physical examination people were included in the study, and the Hp infection rate was 37.30% (505/1354). The difference in Hp infection rates among people of different age groups is statistically significant (P<0.05), with the middle-aged population (41-59 years old) having the highest Hp positive infection rate (45.38%).High salt (41.11%), hot diet (40.56%), history of smoking (45.23%) and drinking (43.80%), less consumption of fruits and vegetables (43.73%), irregular exercise (41.29%), irregular diet People who frequently eat out (43.56%) and eat out frequently (42.57%) have a higher Hp infection rate (P<0.05).After adjusting for demographic factors such as gender, age, place of residence and education level, multivariate Logistic regression results showed that high-salt diet (OR=3.975, 95%CI: 2.670-5.917) and hot diet (OR=3.357, 95%CI: 2.291-4.919), smoking (OR=1.458, 95%CI: 1.082-1.964), drinking alcohol (OR=1.654, 95%CI: 1.279-2.138), eating fruits and vegetables (OR=1.759, 95%CI: 1.345-2.301), regular exercise (OR=1.822, 95%CI: 1.371-2.421), regular diet (OR=1.893, 95%CI: 1.391-2.575), eating out (OR=1.690, 95%CI: 1.277-2.237) were associated with the risk of Hp infection (P<0.05). Conclusion The positive infection rate of Hp among the physical examination population in Xuzhou is slightly lower than the average epidemic level in China. Cultivating healthy eating and living habits can effectively reduce the risk of Hp infection.

ObjectiveTo verify the association between the Ddit3-Trib3-Akt signaling pathway and rat spermatogenesis by constructing an in vitro co-culture system of testis. MethodsTesticular tissue blocks from 20-25-day-old male rats were placed in an in vitro culture system, and the culture medium was replaced every 2 to 3 days. PCR was used to verify the expression of marker genes of various spermatogenic cells. RNA interference technology was employed to verify the correlation between the Ddit3-Trib3-Akt signaling pathway and rat spermatogenesis. ResultsThe co-culture system could be continuously cultured for more than 2.5 months in vitro. RT-PCR showed that specific marker genes of spermatogonia, spermatocyte and spermoblast were expressed. The RNA and protein expression of Trib3 and Akt changed after the knocking down of Ddit3 and Trib3, respectively. It demonstrated the existence of Ddit3-Trib3-Akt signaling pathway in rat spermatogenesis. ConclusionThe culture time of more than 2.5 months indicates that the culture system can temporarily maintain the proliferation and differentiation of stem cells, and simultaneously maintain and stabilize spermatogenesis in a simple system. The successful validation of the Ddit3-Trib3-Akt signaling pathway also confirms that this culture system can be used to study possible molecular mechanisms of spermatogenesis in vitro.

Ischemic stroke (IS) represents a major global health challenge with complex pathological mechanisms. Although modern therapies such as intravenous thrombolysis and endovascular thrombectomy have advanced, their application remains constrained by narrow therapeutic time windows, hemorrhagic risks, and uneven distribution of medical resources. Traditional Chinese medicine (TCM) demonstrates unique value in the prevention and treatment of IS, owing to its multi-component, multi-target, and holistic regulatory characteristics. This review summarized the molecular mechanisms by which active ingredients and compound formulations of TCM exert therapeutic effects against IS through the regulation of inflammatory responses, oxidative stress, excitatory toxicity, apoptosis, and autophagy. Studies have indicated that components such as curcumin, baicalin, and astragaloside Ⅳ inhibit microglial activation and the nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome to attenuate neuroinflammation, activate the nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase-1 (HO-1) pathway to alleviate oxidative stress, modulate glutamate receptor function to counteract excitatory toxicity, and regulate the B-cell lymphoma 2(Bcl-2)/Bcl-2-associated X protein (Bax), cysteine aspartate-specific protease (Caspase), and phosphatidylinositol 3 kinases (PI3K)/protein kinase B (Akt) signaling pathways to suppress neuronal apoptosis. Recent research has further revealed that TCM can modulate ferroptosis by targeting key proteins glutathione peroxidase 4 (GPX4) and acyl-coenzyme A synthetase long-chain family member 4 (ACSL4) to maintain iron homeostasis, intervene in the "microbiota-gut-brain axis" to ameliorate dysbiosis and reduce neuroinflammation, utilize exosomes for brain-targeted drug delivery, and influence neural repair processes through epigenetic regulation. Furthermore, the review discussed the integrated mechanisms of compound formulations, such as Buyang Huanwu Decoction, in improving cerebral microcirculation and promoting neurovascular remodeling via multi-component synergy. It also analyzed the strategy and advantages of integrating TCM with Western medicine for IS treatment, providing a novel theoretical foundation and research directions for future investigations and clinical translation of TCM in IS management.

OBJECTIVE To investigate the efficacy and safety of Wuling capsules combined with fluoxetine in the treatment of adolescents with first-episode moderate-to-severe depressive disorder accompanied by insomnia. METHODS The clinical data of 476 adolescents with first-episode moderate-to-severe depression accompanied by insomnia admitted to our hospital from June 2022 to May 2025, were retrospectively collected. According to the initial treatment regimen, patients were divided into a control group (241 cases, treated with fluoxetine alone) and an observation group (235 cases, treated with Wuling capsules combined with fluoxetine). The depression severity (Hamilton Depression Rating Scale-17 Item and the Self-Rating Depression Scale scores), sleep quality (Pittsburgh Sleep Quality Index score, sleep latency, wake after sleep onset, total sleep time, sleep efficiency), serum neuroendocrine indicator (cortisol) and inflammatory markers (C-reactive protein, interleukin-6) were compared between the two groups before treatment and at 4th and 8th weeks of treatment. The effective rate at 8th weeks and the occurrence of adverse drug reactions (ADRs) were also compared between the two groups. RESULTS Before treatment, there were no significant differences in depression severity, sleep quality, serum neuroendocrine indicator, and inflammatory markers between the two groups ( P >0.05). At 4th and 8th weeks, both groups showed significant improvement in these indicators compared to those before treatment, with the observation group demonstrating significantly greater improvement than the control group at the corresponding time points ( P <0.05). At 8th week, the eff ective rate of the observation group was 90.21%, significantly higher than 80.50% in the control group ( P <0.05). The incidence of nausea, headache, fatigue, dry mouth, and palpitations, as well as the total incidence of ADRs, did not differ significantly between the two groups ( P >0.05). CONCLUSIONS Wuling capsules combined with fluoxetine can significantly improve the effective rate in adolescents with first-episode moderate-to-severe depression accompanied by insomnia, accelerate the relief of depressive symptoms, improve sleep quality, and reduce serum neuroendocrine indicator and inflammatory markers, with a favorable safety profile.
10.Research progress on anticoagulant therapy in patients with liver cirrhosis complicated with portal vein thrombosis
China Pharmacy 2026;37(4):533-539
Portal vein thrombosis (PVT) is a common and severe complication of liver cirrhosis. Anticoagulant therapy for PVT in these patients is particularly challenging due to the coexistence of abnormal coagulation function and bleeding risk. This article reviews recent research findings, domestic and international guidelines, and expert consensus regarding anticoagulant therapy for liver cirrhosis complicated by PVT. The review focuses on four key aspects: the underlying causes of the high incidence of PVT, its clinical manifestations and diagnosis, anticoagulant treatment decision-making (including determining indications, timing, and course selection), and rational drug use. The evidence indicates that the high incidence of PVT in patients with liver cirrhosis results from the interplay of multiple factors. Currently, portal venous stasis, a systemic hypercoagulable state, and vascular endothelial damage are widely recognized as the three primary risk factors for PVT formation. The clinical manifestations of liver cirrhosis complicated by PVT are diverse,diagnosis requires comprehensive evaluation based on clinical context, imaging examination, and laboratory tests, with imaging examination as the cornerstone. Anticoagulant therapy can significantly improve the thrombus recanalization rate in PVT, reduce the risk of thrombus progression, and does not increase the risk of portal hypertension-related bleeding. Regarding treatment timing, initiating anticoagulation within six months of diagnosis, particularly within two weeks, can significantly enhance the recanalization rate. Commonly used anticoagulants in clinical practice for liver cirrhosis with PVT include heparins, vitamin K antagonists (VKAs), and direct oral anticoagulants (DOACs). Among these, substantial evidence supports low-molecular-weight heparin as a first-line agent. DOACs have demonstrated favorable efficacy and safety in patients with compensated liver cirrhosis and PVT; however, their use in patients with decompensated liver cirrhosis and PVT warrants extra caution. A treatment duration of at least six months is generally recommended. Long-term anticoagulation should be considered for patients with liver cirrhosis and PVT who have mesenteric vein involvement, are awaiting liver transplantation, or have an inherited thrombophilia.
