ObjectiveTo explore the effects of Jingui Shenqiwan (JSW) and Liuwei Dihuangwan (LDW) on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group, the other six groups were as follows: a group of both males and females receiving JSW (3.0 g·kg-1), a group of both males and females receiving LDW (4.5 g·kg-1), a group of males receiving water and females receiving JSW, a group of males receiving water while females receiving LDW, a group of females receiving water while males receiving JSW, and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 (female∶male) ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth, which was followed by the observation of newborn mice, calculation of their average number, and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment, the weights of the thymus and spleen were measured to calculate the organ coefficients, and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems, while novel object recognition test (NOR) was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction (Real-time PCR) assay, and protein expression was analyzed with Western blot. ResultsCompared with the control group, oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together (P<0.05), while LDW showed a trend but no statistical significance. Additionally, compared with the control group, JSW could upregulate the gene expression of gonadotropin-releasing hormone (GnRH) in the thalamus, as well as reproductive stem cell factor (SCF) and tyrosine kinase receptor (c-Kit) in the testes and reproductive stem cell marker mouse vasa homologue (MVH) in the ovaries, upregulate the expression of proteins influencing neuronal functional activity, such as brain-derived neurotrophic factor (BDNF), in hippocampal neurons (P<0.05), and enhance sucrose preference in male mice (P<0.05). Compared with the control group, JSW significantly increased sucrose preference and novel object recognition index in offspring mice (P<0.05), which was related to the upregulation of hippocampal dopamine D1 receptor (D1R) and N-methyl-D-aspartate receptor (Nmdar) gene expression. Compared with the control group, both JSW and LDW could upregulate the protein expression of glucocorticoid receptor (GR), BDNF, and tyrosine kinase receptor B (TrkB) in the hippocampus of offspring mice (P<0.05). ConclusionJSW significantly enhances the reproductive ability of normal mice, which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally, JSW has a certain regulatory effect on the brain function of the offspring mice.

Xuanfuhua Decoction (旋覆花汤) is considered as the theoretical prototype of the method of unbloc-king collaterals with acrid and moistened medicinals. Guided by the theories of "chronic disease entering the collaterals" and "collaterals performing their functions when there is free flow", YE Gui further developed this approach into a systematic method. The core of this approach lies in dispersing and opening constraint with acrid medicinals, nourishing and harmonizing collaterals with moistened medicinals, eliminating pathogens and unblocking collaterals with insect medicinals. The disease course of idiopathic pulmonary fibrosis (IPF) is prolonged, with a complex of deficiency and excess, and chronic disease entering the collaterals. The core pathogenesis involves lung collaterals obstruction, fluid depletion with blood stasis, and chronic disease entering the collaterals. Treatment can be guided by the method of unblocking collaterals with acrid and moistened medicinals based on Xuanfuhua Decoction, following a strategy of "dispersing and unblocking, moistening and nourishing, penetrating and venting". Specifically, for lung collaterals obstruction, acrid medicinals can be used to disperse lung qi and open bi (痹). In case of fluid depletion and blood stasis, moistened medicinals for nourishing lung collaterals are suggested to restore vitality. For chronic disease ente-ring collaterals, it is advised to search and eliminate collateral pathogens in order to dissipate masses.

Objective: To investigate the correlation between color parameters (L*, a*, b*, Eab*) and the contents of reducing sugars, total polysaccharides, total oligosaccharides, as well as four saccharides (fructose, glucose, sucrose, and kestose) during the nine cycles of steaming and sun-drying processing of Polygonatum kingianum, and to preliminarily explore the optimal processing duration.
Methods: The color changes were objectively evaluated using a colorimeter. The anthrone-sulfuric acid method was employed to determine total polysaccharides and oligosaccharides. The 3,5-dinitrosalicylic acid (DNS) colorimetric method was used to measure total reducing sugar content. High-performance liquid chromatography coupled with charged aerosol detection (HPLC-CAD) was applied for quantitative analysis of fructose, glucose, sucrose, and kestose. Multivariate statistical analysis was conducted to assess samples from different processing stages.
Results: Significant variations in color and component contents were observed across processing stages. The herbal pieces progressively darkened with increased processing cycles: brightness (L*) and total color difference (Eab*) initially decreased then stabilized, while a* (red-green) and b* (yellow-blue) values first increased then declined. Total polysaccharides and oligosaccharides showed overall decreasing trends, whereas reducing sugars initially increased before stabilizing. Fructose and glucose levels rose continuously, while sucrose and kestose decreased progressively, becoming undetectable after five cycles.
Conclusion: The chromatic alteration and saccharide composition of P. kingianum showed significant correlation with processing duration. Both total color difference (Eab*) and reducing sugar content stabilized after four processing cycles (12 hours), suggesting that four cycles of steaming and sun-drying may represent the optimal processing duration.

ObjectiveTo investigate the effect and mechanism of Shengxian Yixin Granule (升陷益心颗粒, SYG) in treating heart failure with preserved ejection fraction (HFpEF). MethodsExperiment 1: Forty male C57BL/6 mice were randomly divided into control group, model group, low-dose [25 mg/(kg·d)], medium-dose [50 mg/(kg·d)], and high-dose [(75 mg/(kg·d)] SYG groups, with 8 mice per group. Except for the control group, HFpEF was induced by a high-fat diet combined with Nω-nitro-L-arginine methyl ester in drinking water for 16 weeks. After 10 weeks of modeling, treatment groups received corresponding doses of SYG by gavage, while the control group and model group received equal volume of normal saline, for 6 weeks. After 6 weeks of administration, the body weight, blood pressure including systolic blood pressure (SBP) and diastolic blood pressure (DBP), and heart weight-to-tibia length ratio (HW/TL) were recorded. Echocardiography was used to evaluate left ventricular ejection fraction (LVEF) and the ratio of early to late diastolic transmitral flow velocity (E/A). Plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and C-reactive protein (CRP) levels were measured by ELISA. The expression level of brain natriuretic peptide (BNP) in heart tissue was detected by qRT-PCR. Blood lipid levels, including low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and total cholesterol (TC), were determined by a biochemical analyzer. Splenic proportions of M1 macrophages, M2 macrophages, T helper 17 (Th17) cells, and regulatory T (Treg) cells were analyzed by flow cytometry. Experiment 2: RAW 264.7 cells were stimulated with lipopolysaccharide (LPS) to establish an M1 macrophage polarization model, and then treated with SYG-containing serum for 24 h. The cells were divided into four groups, including blank serum group, high-dose SYG-containing serum group, LPS group, and LPS plus high-dose SYG-containing serum group. Combined with asignal transducer and activator of transcription 3 (Stat3) inhibitor for 24 h, the cells were divided into a lipopolysaccharide group, a high-dose SYG-containing serum group, an inhibitor group, and high-dose SYG-containing serum plus inhibitor group. The expression levels of inducible nitric oxide synthase (iNOS) and interleukin-1β (IL-1β) in each group were detected by qRT-PCR. The protein levels of iNOS, IL-1β, Stat3, and phosphorylated Stat3 (p-Stat3) were detected by Western Blotting. ResultsExperiment 1: Compared to the control group, the model group showed significantly decreased E/A ratio, and increased cardiac BNP expression, plasma NT-proBNP,HW/TL ratio, body weight, TC, LDL-C, SBP, and DBP, as well as shortened exhaustion distance and exhaustion time (P<0.05 or P<0.01). Compared to the model group, the E/A ratio increased in the low-, medium-, and high-dose SYG groups; cardiac BNP expression decreased in the low- and high-dose groups, and plasma NT-proBNP levels decreased in the high-dose group; the HW/TL ratio and body weight decreased, while exhaustion distance and exhaustion time increased in the medium- and high-dose groups; TG levels decreased in the low- and medium-dose groups, and LDL-C levels decreased in the medium- and high-dose groups; SBP and DBP decreased in the low-, medium-, and high-dose groups (P<0.05 or P<0.01). Compared to the low-dose SYG group, body weight decreased, and both exhaustion distance and exhaustion time increased in the medium- and high-dose groups (P<0.05 or P<0.01). Compared to the medium-dose SYG group, the exhaustion time increased in the high-dose SYG group (P<0.01). Experiment 2: In the LPS‑induced M1 macrophage polarization model, compared to the blank serum group, the LPS group showed significantly increased mRNA and protein expression of iNOS and IL‑1β, as well as the p‑Stat3/Stat3 ratio (P<0.01). Compared to the LPS group, the high‑dose SYG-containing serum plus LPS group showed significantly decreased mRNA and protein expression of iNOS and IL‑1β, as well as the p‑Stat3/Stat3 ratio (P<0.05 or P<0.01). Compared to the LPS group, the inhibitor group also showed significantly reduced these parameters (P<0.05 or P<0.01). ConclusionSYG can improve cardiac function, ventricular remodeling, exercise capacity, and lipid metabolism in HFpEF mice, while inhibiting inflammatory responses. Its mechanism may be related to the regulation of the Stat3 signaling pathway and inhibition of M1 macrophage polarization.

ObjectiveTo compare the contents and relative molecular weight distributions of proteins and polypeptides in Naoxuekang dropping pills, Huoxue Tongmai capsules and Maixuekang capsules of Hirudo single medicinal preparations, to evaluate the in vitro anticoagulant, antiplatelet and fibrinolytic activities of the three preparations, and to investigate the effects of temperature, pH and digestive enzymes on the anticoagulant activities of the three preparations. MethodsThe contents of soluble proteins and polypeptides in the three preparations were determined by bicinchoninic acid assay(BCA) and Bradford method, and the relative molecular weight distributions of the three preparations were determined by electrophoresis combined with gel chromatography. The antithrombin activity of the three preparations was evaluated by fibrinogen-thrombin time(Fibg-TT) method, and their anticoagulant activities were further assessed by the elongations of activated partial thromboplastin time(APTT), prothrombin time(PT) and thrombin time(TT). The antiplatelet aggregation activities of the three preparations were measured by turbidimetry and the fibrinolytic activities were measured by fibrin plate method. Relative TT was used as index to investigate the effects of temperature, pH and digestive enzyme buffer on anticoagulant activities of the three preparations. ResultsAt the lowest single dosage, the contents of proteins and polypeptides were in the order of Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. Both Huoxue Tongmai capsules and Maixuekang capsules had 11 electrophoretic bands between 4.0 kDa and 90 kDa, the bands of Maixuekang capsules were more clear in the range of >25 kDa, and there was 1 obvious band at 14 kDa for the two capsules. Huoxue Tongmai capsules had one specific band at 9.0 kDa and Maixuekang capsules had one specific band at 48.0 kDa. Naoxuekang dropping pills only had 2 electrophoretic bands at 6.5 kDa and 8.5 kDa, primarily containing peptides below 2 kDa, most of which were oligopeptides. The anticoagulant activity concentrations of the three preparations exhibited a certain dose-dependent effect. At the lowest single dosage, The anticoagulant activity concentrations were ranked as Naoxuekang dropping pills>Huoxue Tongmai capsules>Maixuekang capsules. The prolongation effect of the three preparations on coagulation time was dose-dependent. At the same concentration, the prolongation effect of Naoxuekang dropping pills and Huoxue Tongmai capsules was APTT prolongation rate>TT prolongation rate>PT prolongation rate, whereas for Maixuekang capsules, the sequence was TT prolongation rate>APTT prolongation rate>PT lengthening rate. At the single minimum dosage, the order of APTT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules≈Naoxuekang dropping pills, the order of PT prolongation rate was Naoxuekang dropping pills≈Maixuekang capsules>Huoxue Tongmai capsules, and the order of TT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. The three preparations showed dose-dependent effects on platelet aggregation induced by adenosine diphosphate(ADP) and arachidonic acid(AA), and the effect induced by ADP was stronger than that induced by AA. The anti-platelet aggregation effect of Naoxuekang dropping pills was significantly stronger than that of Maixuekang capsules(P<0.01), whereas Huoxue Tongmai capsules had the effect of promoting platelet aggregation. None of the three preparations had the ability to dissolve fibrin. The anticoagulant activity of Naoxuekang dropping pills was least affected by heating, while the activities of the two capsules decreased significantly within 5 min above 80 ℃, and continued to decrease within 2 h. Compared with pure water, the anticoagulant activities of the three preparations could be increased by 1-3 times under strong acidity(pH 1-3). In the pepsin buffer, the anticoagulant activity of Naoxuekang dropping pills could be increased by 1-3 times, while the anticoagulant activities of Huoxue Tongmai capsules and Maxuekang capsules were significantly decreased, the lowest levels were about 60% and 20%, respectively. In trypsin buffer, the anticoagulant activities of Naoxuekang dropping pills, Huoxue Tongmai capsules and Maixuekang capsules decreased significantly, and the lowest levels decreased to about 41%, 41% and 35%, respectively. ConclusionThe contents of proteins and polypeptides and relative molecular weights of the preparations derived from lyophilized fresh Hirudo powder, dried Hirudo powder and reflux extract of Hirudo decrease sequentially, and the anticoagulant activity decrease gradually, but the anticoagulant pathway is different. And the anti-platelet aggregation activity of the reflux extract is significantly enhanced. The heat resistance and gastrointestinal stability of the three preparations increase successively, and the first two are suitable for enteric-soluble preparations, while the latter is suitable for routine oral administration. The above results can provide data reference for the rationality of different preparation methods, active substances, pharmacodynamics and mechanism of Hirudo preparations.

Numerous research conducted in recent years has revealed that gut microbial dysbiosis, such as modifications in composition and activity, might influence lung tissue homeostasis through specific pathways, thereby promoting susceptibility to lung diseases. The development and progression of lung cancer, as well as the effectiveness of immunotherapy are closely associated with gut flora and metabolites, which influence immunological and inflammatory responses. During abnormal proliferation, non-small cell lung cancer cells acquire more substances and energy by altering their own metabolic pathways. Glucose and amino acid metabolism reprogramming provide tumor cells with abundant ATP, carbon, and nitrogen sources, respectively, providing optimal conditions for tumor cell proliferation, invasion, and immune escape. This article reviews the relationship of immune response with gut flora and metabolic reprogramming in non-small cell lung cancer, and discusses the potential mechanisms by which gut flora and metabolic reprogramming affect the occurrence, development, and immunotherapy of non-small cell lung cancer, in order to provide new ideas for precision treatment of lung cancer patients.

Based on the interleukin-17(IL-17) signaling pathway, this study explores the effect and mechanism of Bufei Decoction on Klebsiella pneumoniae pneumonia in rats. SD rats were randomly divided into the control group, model group, Bufei Decoction low-dose group(6.68 g·kg~(-1)·d~(-1)), Bufei Decoction high-dose group(13.36 g·kg~(-1)·d~(-1)), and dexamethasone group(1.04 mg·kg~(-1)·d~(-1)), with 10 rats in each group. A pneumonia model was established by tracheal drip injection of K. pneumoniae. After successful model establishment, the improvement in lung tissue damage was observed following drug administration. Core targets and signaling pathways were screened using transcriptomics techniques. Real-time fluorescence quantitative polymerase chain reaction was used to detect the mRNA expression of core targets interleukin-6(IL-6), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and chemokine CXC ligand 6(CXCL6). Western blot was used to assess key proteins in the IL-17 signaling pathway, including interleukin-17A(IL-17A), nuclear transcription factor-κB activator 1(Act1), tumor necrosis factor receptor-associated factor 6(TRAF6), and downstream phosphorylated p38 mitogen-activated protein kinase(p-p38 MAPK), and phosphorylated nuclear factor-κB p65(p-NF-κB p65). Apoptosis of lung tissue cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling(TUNEL). The results showed that, compared with the control group, the model group exhibited significant pathological damage in lung tissue. The mRNA expression of IL-6, IL-1β, TNF-α, and CXCL6, as well as the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly increased, and the number of apoptotic cells was notably higher, indicating successful model establishment. Compared with the model group, both low-and high-dose groups of Bufei Decoction showed reduced pathological damage in lung tissue. The mRNA expression levels of IL-6, IL-1β, TNF-α, and CXCL6, and the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly decreased, with a significant reduction in apoptotic cells in the high-dose group. In conclusion, Bufei Decoction can effectively improve lung tissue damage and reduce inflammation in rats with K. pneumoniae. The mechanism may involve the regulation of the IL-17 signaling pathway and the reduction of apoptosis.

Bronchiectasis(BE) is the third major chronic airway disease, and its incidence rate shows a continuously increasing trend. Bronchiectasis is a highly heterogeneous chronic airway disease. Due to structural alterations, airflow limitation, and mucus hypersecretion, clinical treatment faces many challenges. Particularly, problems including Pseudomonas aeruginosa-dominant drug-resistant bacterial colonization, recurrent infections, airway mucus hypersecretion, and impaired lung function are the most urgent, requiring long-term and personalized treatment and management integrating traditional Chinese and western medicine to prevent the recurrence and continuous progression of the disease. In recent years, both traditional Chinese medicine and western medicine have made certain progress in pathogenesis theories, clinical studies, and basic research regarding the therapeutic challenges of bronchiectasis. Therefore, this paper summarized relevant research from the past 10 years and explored future directions and potential advantages of integrated traditional Chinese and western medicine treatment, providing references for optimizing the clinical management strategies for bronchiectasis.
