OBJECTIVE To establish the UPLC fingerprint and the method for multi-component content determination in Jingangteng capsules, and to evaluate its quality by combining chemical pattern recognition analysis. METHODS An UPLC method was established. Separation was performed on a Zorbax SB-C 18 Rapid Resolution HD column, with acetonitrile-0.1% formic acid as the mobile phase for gradient elution.Using the Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicines (2012 edition), UPLC fi ngerprints were established for 10 batches of Jingangteng capsules, and similarity was evaluated. SPSS 22.0 and SIMCA 14.1 software were used to perform hierarchial-cluster analysis and orthogonal partial least squares discriminant analysis (OPLS-DA), respectively. The same UPLC method was employed to determine the contents of chlorogenic acid, 3,5-dihydroxy-2-methylbenzoic acid-3- O -glucoside (M1), caffeic acid, astilbin, oxyresveratrol, quercitrin and resveratrol in the 10 batches of samples. RESULTS A total of 17 common peaks were identified in UPLC fingerprints of the 10 batches of samples, of which 7 were identified as chlorogenic acid, M1, caffeic acid, astilbin, oxyresveratrol, quercitrin, and resveratrol. The similarities of 10 batches of samples ranged from 0.820 to 0.985. The results of hierarchial-cluster analysis showed that 10 batches of samples were grouped into four categories: S1-S4 formed one group, S5 and S6 formed another, S7, S8 and S10 formed a third, and S9 formed a fourth, consistent with the OPLS-DA results; the variable importance projection values for peaks 7, 10, 2, 16 (resveratrol), 13 (oxyresveratrol), 11, 6 (caffeic acid), 5 (M1) and 15 (quercitrin) were >1. Quantitative analysis results showed that the contents of chlorogenic acid, M1, caffeic acid, astilbin, oxyresveratrol, quercitrin, and resveratrol were 1.650 8-4.213 7, 0.636 2-2.161 7, 0.031 0-0.086 5, 0.239 1-1.069 3, 0.211 9-1.104 0, 0.488 8-2.399 2, and 0.164 0-0.699 8 mg/g, respectively. CONCLUSIONS UPLC fingerprint and content determination methods established in this study are simple to operate, accurate, reliable and reproducible; when combined with chemical pattern recognition analysis, they can be used to evaluate the quality of Jingangteng capsules. Nine components, such as resveratrol, oxyresveratrol, caffeic acid, M1 and quercitrin, may serve as markers of quality variation.

OBJECTIVE To provide empirical basis for promoting the dynamic adjustment of the pharmaceutical care catalogue and the formulation of policies such as hierarchical payment of medical insurance. METHODS A multicenter cross- sectional survey method was adopted to conduct a questionnaire survey among 424 inpatients in 22 tertiary medical institutions in 12 prefecture-level cities of Hubei Province to evaluate their demand for pharmaceutical care, willingness to pay and preference for service forms. Combined with univariate and multivariate Logistic regression analysis, the influencing factors and key factors that affect patients’ willingness to pay for pharmaceutical care were identified. RESULTS Only 39.86% of the patients were aware of pharmaceutical care or pharmacists, and 89.62% of the patients hope to receive pharmaceutical care. Among the 16 types of pharmaceutical care, the patients surveyed had a relatively high recognition rate for guidance on drug usage and dosage, notification of medication precautions, and the identification, prevention and handling of adverse drug reactions. 96.70%, 95.30%, and 94.12% respectively expressed strong approval and approval. The demand for services such as insurance-related policy consultation, popular science on the mechanism of drug action, and assessment of the combined use of traditional Chinese and Western medicines was relatively low, with 61.65%, 68.47%, and 68.47% expressing strong approval and approval respectively. The positive influencing factors of willingness to pay were household monthly income > 5 000 yuan (OR=1.742), awareness of pharmaceutical care or pharmacists (OR=3.620), and the desire to receive pharmaceutical care (OR=4.686) (P<0.05), while self-rating health as “good” (OR=0.390) was a negative influencing factor (P<0.05). Cardiovascular and cerebrovascular diseases (54.48%) and antihypertensive drugs (45.05%) were the service scenarios that the surveyed patients most hope to be covered. 85.14% of the patients preferred “service when xiaochnye@126.com needed”, with a single service duration of less than 10 minutes being appropriate (84.43%), and the willingness to pay within 20 yuan being the main type (85.38%). CONCLUSIONS Based on the characteristics of patients’ needs and payment behaviors, it is suggested that our country could consider establishing a hierarchical payment mechanism for pharmaceutical care, and focus on differentiated design in combination with diseases and medication situations. At the same time, the rights, responsibilities and service standards of resident pharmacists in the links such as medication reorganization and medical order review should be further clarified to comprehensively enhance the clinical value and policy operability of pharmaceutical care.

OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease (NAFLD). METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group, atorvastatin group[positive control, 2 mg/(kg·d)], and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/(kg·d)], with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine transaminase (ALT), aspartate transaminase (AST), tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail:591146765@qq.com metabolomics results, Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B (NF-κB)/NOD-like receptor family protein 3 (NLRP3) signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG, TC, LDL-C, AST, ALT, TNF-α, IL-1β, IL-6, IL-18, while increased the level of HDL-C, and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats, significantly increased the relative abundance of Romboutsia and Oscillospira, and significantly decreased the relative abundance of Blautia (P<0.05). They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis, fatty acid degradation, O-antigen nucleotide sugar biosynthesis, etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α, and the protein expression levels of NLRP3, caspase-1 and ASC (P<0.05 or P<0.01). CONCLUSIONS Jingangteng capsules could improve inflammation, lipid accumulation and liver injury in NAFLD rats, regulate the disorders of gut microbiota and metabolisms, and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C2P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn2+ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C2P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

Ultra performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry/mass spectrometry(UPLC-Q-TOF-MS/MS), network pharmacology, and animal experiments were integrated o explore the blood glucose-lowering effects and mechanisms of Poria aqueous extract. Firstly, the active components of Poria aqueous extract were identified by UPLC-Q-TOF-MS/MS. Subsequently, network pharmacology was employed to predict the blood glucose-lowering components and mechanisms of Poria aqueous extract. Finally, a rat model of diabetes mellitus, 16S rDNA sequencing, and Western blot were employed to investigate the blood glucose-lowering effect and mechanism of Poria aqueous extract. A total of 39 triterpenoids were identified in the Poria aqueous extract, among them, 25-hydroxypachymic acid, 25α-hydroxytumulosic acid, 16α-hydroxytrametenolic acid, polyporenic acid C, and tumulosic acid may be the main active ingredients for treating diabetes. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis revealed that Poria might exert its therapeutic effects through multiple pathways such as NOD-like receptor signaling pathway, nuclear factor-kappa B(NF-κB) signaling pathway, and tumor necrosis factor(TNF) signaling pathway. The results of animal experiments demonstrated that Poria aqueous extract significantly reduced the levels of blood glucose and lipids and regulated the intestinal flora in diabetic rats. The main affected taxa included g_Escherichia-Shigella, g_Corynebacterium, g_Prevotella_9, g_Prevotellaceae_UCG-001, and g_Bacteroidota_unclassified. In addition, Poria aqueous extract lowered the levels of D-lactic acid and lipopolysaccharide, alleviated colonic mucosal damage, significantly down-regulated the protein levels of NOD-like receptor pyrin domain-containing protein 3(NLRP3), NF-κB, and TNF-α, and significantly up-regulated the protein levels of zonula occludens 1 and occludin in diabetic rates. Poria aqueous extract may play a role in treating diabetes mellitus by repairing the intestinal flora disturbance, protecting the intestinal barrier function, and inhibiting the NF-κB/NLRP3 signaling pathway. The results provide a scientific basis for clinical application and expansion of indications of Poria.

Transcatheter arterial embolization (TAE) is the mainstay for treating advanced hepatocellular carcinoma (HCC), and the performance of the embolization material is crucial in TAE. With the development of medical imaging and the birth of "X-ray-free" technologies, we designed a new dual-mode imaging material of dimethoxy tetraphenyl ethylene (DMTPE) via emulsification by mixing poly(N-isopropylacrylamide-co-acrylic acid) (PNA) with lipiodol and fluorocarbons, which was evaluated for temperature sensitivity, stability, and dual-mode visualization in vitro. Additionally, blood vessel casting embolization and renal artery imaging were assessed in healthy rabbits. In a rabbit model with a VX2 tumor, the effectiveness of TAE for treating HCC was examined, with an emphasis on evaluating long-term outcomes of embolization and its effects on tumor growth, necrosis, and proliferation through imaging techniques. In vitro experiments confirmed that the temperature-sensitive dual-oil-phase Pickering emulsion had good flow, stable contrast, and embolism when the oil-to-oil ratio and water-to-oil ratio were both 7:3 ( v/v) and stabilized with 8% PNA. Similarly, in vivo, arterial embolization confirmed the excellent properties of DMTPE prepared at the abovementioned ratios. It was observed that DMTPE not only has an antitumor effect but can also achieve dual imaging using X-rays and ultrasound, making it a promising excellent vascular embolization material for TAE in tumor treatment.

Objective To analyze the risk factors for chronic cough following pulmonary surgery in patients with non-small cell lung cancer (NSCLC). Methods A retrospective analysis was conducted on 427 NSCLC patients who underwent pulmonary surgery in the Department of Thoracic Surgery, The First Affiliated Hospital of the University of Science and Technology of China, between January 2021 and June 2023. Patients were categorized into a chronic cough group (103 patients) and a non-chronic cough group (324 patients) based on the presence of cough at 8 weeks post-surgery. A comparative analysis was performed between the two groups, considering gender, age, smoking history, comorbidities, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration. Factors showing statistical significance in univariate analysis underwent multivariate logistic regression analysis. Results Among the 427 patients undergoing pulmonary surgery, there were 165 males and 262 females, with an average age of (59.93±12.11) years. The incidence of chronic cough was 24.12%. Univariate analysis revealed significant differences in smoking history, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration ≥135.5 minutes, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration (P<0.05). Multivariate logistic regression analysis indicated that the surgical site (right upper lung), operative techniques (lobectomy), lymph node dissection, and anesthesia time ≥135.5 minutes were independent risk factors for chronic cough following pulmonary surgery. Conclusion Patients undergoing right upper lung surgery, lobectomy, lymph node dissection, and experiencing anesthesia duration ≥135.5 minutes are at a higher risk of developing chronic cough post-pulmonary surgery.
