ObjectiveTo investigate the effects of Zuoguiwan on osteoclast activation induced by breast cancer and its mechanism. MethodsTo simulate breast cancer-induced osteoclastic bone metastasis, RAW264.7 cells were cultured in conditioned medium containing 50% supernatant of MDA-MB-231 breast cancer cells. The dosages of Zuoguiwan used in the experiment were sera containing 5% and 10% Zuoguiwan. Tartrate-resistant acid phosphatase (TRAP) staining was used to detect osteoclast activation. Enzyme-linked immunosorbent assay (ELISA) was used to measure Cathepsin K secretion from RAW264.7 cells. Real-time quantitative polymerase chain reaction (PCR) was used to detect the mRNA expression levels of osteocalcin (OCN) and bone sialoprotein (BSP). Immunoprecipitation was employed to detect the interaction between Runt-related transcription factor 2 (Runx2) and core binding factor β subunit (CBF-β). Western blot was used to assess the protein expression of Runx2, phosphorylated Runx2 (p-Runx2), extracellular signal-regulated kinases 1/2 (ERK1/2), p-ERK1/2, p38 mitogen-activated protein kinase (MAPK), p-p38 MAPK, and CBF-β. ResultsCompared with the blank group, the MDA-MB-231 cell supernatant group showed a significant increase in TRAP-positive cell counts and Cathepsin K secretion. Meanwhile, the expression levels of p-Runx2, Runx2-CBF-β interaction, BSP and OCN mRNA, p-p38 MAPK, and p-ERK1/2 proteins were significantly decreased (P<0.01). Compared with the MDA-MB-231 cell supernatant group, Zuoguiwan-containing sera significantly reduced TRAP-positive cell counts and Cathepsin K secretion (P<0.01), significantly increased p-Runx2, BSP and OCN mRNA expression, as well as p-p38 MAPK and p-ERK1/2 protein levels, and promoted the interaction between Runx2 and CBF-β (P<0.01). No significant change in Runx2 expression was observed. Compared to the blank group, the BVD-523 group showed significantly lower expression of p-p38 MAPK and p-ERK1/2 proteins (P<0.01). Compared with the BVD-523 group, both low and high concentration Zuoguiwan-containing sera groups showed significantly higher p-p38 MAPK expression (P<0.01), and the high concentration Zuoguiwan group also exhibited a significant increase in p-ERK1/2 expression (P<0.01), while no statistical difference was found in the low-dose group. ConclusionZuoguiwan inhibits osteoclast activation by inducing phosphorylation of the key transcriptional regulator Runx2 in intra-osteoclast bone formation, and this process is closely associated with the activation of the p38 MAPK/ERK signaling pathway.

ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis (IPF). MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation (30 patients) and control groups (30 patients). All patients underwent standard Western medical therapy. Additionally,the observation group received Shenlong decoction granules,while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each,taken twice daily for three months. The indexes of the patients during the treatment cycle were observed,and the main indexes include traditional Chinese medicine (TCM) syndrome scores and 6 min walk test (6MWT). The secondary indexes include pulmonary function test [actual value/expected value of total lung volume (TLC%),actual value/expected value of vital capacity(FVC%),actual/predicted diffusing capacity of the lung for carbon monoxide(DLCO%),actual/predicted forced expiratory volume in one second (FEV1%),and FEV1/ forced vital capacity (FVC)],blood gas analysis [arterial blood diathesis partial pressure of oxygen (PaO2),partial pressure of carbon dioxide (PaCO2),and arterial oxygen saturation (SaO2)],serum inflammatory factors [transforming growth factor-β1 (TGF-β1),interleukin-4 (IL-4),interleukin-13 (IL-13),interleukin-12 (IL-12),and gamma-interferon (IFN-γ)],and quality of survival evaluation [St George's Respiratory Questionnaire (SGRQ) score]. The patients' clinical manifestations were determined at the end of the treatment, and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study,comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period,the control group achieved a total effective rate of 33.33% (9/27),whereas the observation group demonstrated a total effective rate of 53.85% (14/26),which was statistically superior to the control group (χ2=4.034,P<0.05). After the treatment,the TCM syndrome scores,6MWT,DLCO%,FEV1%,PaO2,PaCO2,TGF-β1,IL-4,IL-13,IL-12,and IFN-γ in the two groups were all significantly improved (P<0.01). Compared with those in the control group after treatment at the same period,the TCM syndrome scores,6MWT,PaO2,and PaCO2 were significantly improved in the observation group after 60 days and 90 days of medication (P<0.01). Three months after the end of medication,the SGRQ score in the observation group showed significant improvement when compared to that in the control group (P<0.05),and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF,enhance exercise tolerance,improve the quality of life,and have certain potential advantages in improving pulmonary function.

Objective To explore the effect of influenza vaccination on the prevention of respiratory tract infection in preschool children. Methods The clinical data of 400 preschool children (1-6 years old) who were diagnosed with respiratory tract infection for the first time in department of pediatrics of Xi'an Third Hospital and second department of respiratory medicine of Xi'an Children's Hospital were retrospectively analyzed from January 2023 to December 2023, including acute bronchitis, upper respiratory tract infection and pneumonia. According to the actual influenza vaccination status, the patients were divided into vaccination group (n=210) and non-vaccination group (n=190). The incidence of respiratory tract infection was compared between both groups. The fever duration, average course of disease, hospitalization rate, clinical symptoms scores (fever, cough, nasal congestion, sore throat), inflammation indicators [C-reactive protein (CRP), white blood cell count (WBC), neutrophil percentage (NE%)] and recurrence rate after 6 months of follow-up were compared. Results The incidence of respiratory tract infection in the vaccination group was significantly lower than that in the non-vaccination group (21.43% vs 43.16%, P<0.05), and the hospitalization rate was significantly lower compared with that in the non-vaccination group (P<0.05). The scores of fever, cough, nasal congestion and sore throat were lower in the vaccination group than those in the non-vaccination group (P<0.05), and the CRP, WBC and NE% were significantly lower compared to the non-vaccination group (P<0.05). After 6 months of follow-up, the recurrence rate in the vaccination group was 11.11% (5/45), which was significantly lower than 26.83% (22/82) in the non-vaccination group (χ2=0.038, P=4.288<0.05). Conclusion Influenza vaccination can effectively reduce the incidence of respiratory tract infection in preschool children, relieve the symptoms and shorten the disease course after infection. Its preventive effect on influenza is particularly significant, suggesting the importance of strengthening influenza vaccination in preschool children.

Chronic heart failure (CHF) is a complex clinical syndrome that the cardiac output is not enough to meet the metabolic needs of the body, or depends on the increase of filling pressure to compensate. Its high morbidity and mortality pose a serious threat to human health, necessitating attention and active intervention. At present, western medicine treatment of CHF is mainly based on diuretics, intravenous vasodilators, intravenous positive inotropic drugs, etc., which, however, have problems such as long medication cycles, serious side effects, and limited applicable population. Recent studies have shown that traditional Chinese medicine can act in a multi-pathway, multi-component, and multi-target manner, showing unique advantages in the prevention and treatment of CHF. Buyang Huanwutang has the effects of tonifying Qi, activating blood, and dredging collaterals. Clinical and mechanism studies have confirmed that this prescription is effective in treating CHF and its syndromes. The clinical studies can be classified into two categories. Studies of the first category use simple modern medical diagnostic criteria as the inclusion criteria for CHF patients, which can improve the scientificity and objectivity. Studies of the second category uses modern medicine combined with traditional Chinese medicine disease diagnostic criteria for the screening of CHF patients, which helps to improve the accuracy of efficacy evaluation. However, there are problems such as the lack of unified research standards and the insufficiency of mechanism research. In addition, the available studies remain to be classified or summarized. This study systematically sorted out the clinical and mechanism studies of Buyang Huanwutang in the treatment of CHF in recent years to review the research status. In clinical treatment, Buyang Huanwutang can be used alone, or modified, or combined with other prescriptions or Western medicine. The mechanism studies predict that Buyang Huanwutang can ameliorate CHF by regulating the calcium balance, protecting the mitochondrial structure and function, and regulating intestinal flora. This review aims to provide a theoretical basis and practical guidance for the clinical application and optimization and subsequent in-depth study of Buyang Huanwutang in the treatment of CHF.

ObjectiveTo observe ovarian microvascular damage in rats with cold coagulation and blood stasis syndrome and to explore the mechanism by which Liangfang Wenjing decoction improves this condition in rats. MethodsFifty SPF female SD rats were randomly divided into a blank group, a model group, low-dose (8.1 g·kg-1) and high-dose groups (16.2 g·kg-1) of Liangfang Wenjing decoction, and a 4-phenylbutyric acid (0.1 g·kg-1) group, with 10 rats in each group. The ice-water bath method was employed to establish the rat model of cold coagulation and blood stasis syndrome. Concurrent with modeling, Liangfang Wenjing decoction was administered continuously for 21 days, once daily. The rats' syndrome manifestations and estrous cycles were recorded. The enzyme-linked immunosorbent assay (ELISA) was used to detect serum reproductive hormone levels and levels of endothelin-1 (ET-1), nitric oxide (NO), thrombomodulin (TM), and von Willebrand factor (vWF) in ovarian tissue. Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and fibrinogen (FIB) were measured. The ovarian microcirculatory blood perfusion was detected by laser speckle contrast imaging. Hematoxylin-eosin (HE) staining was performed to observe the ovarian histopathology, flow cytometry to detect ovarian apoptosis rate, and transmission electron microscopy to observe the ultrastructure of ovarian microvascular endothelial cells. Western blot was employed to detect the protein expression of endothelial nitric oxide synthase (eNOS), phosphorylated eNOS (p-eNOS), Caspase-3, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), inositol-requiring enzyme1α (IRE1α), p-IRE1α, apoptosis signal-regulating kinase 1 (ASK1), p-ASK1, c-Jun N-terminal kinase (JNK), and p-JNK. Immunofluorescence was used to detect ovarian Bax and Bcl-2 expression in microvascular endothelial cells. ResultsCompared with the blank group, the model group showed signs of cold coagulation and blood stasis syndrome, prolonged estrus cycles, and reproductive hormone disorders. Histopathological results revealed a decrease in follicle counts at all stages and disorganized granulosa cell arrangement. Ovarian microcirculatory perfusion was significantly decreased (P<0.01). PT, APTT, and TT were reduced (P<0.05, P<0.01), while FIB levels were increased (P<0.05). In ovarian tissue, NO content was decreased, while ET-1, vWF, and TM levels were increased significantly (P<0.01). The apoptosis rate of ovarian cells was markedly increased (P<0.01). Furthermore, p-eNOS/eNOS and Bcl-2 were decreased (P<0.05), whereas Bax, cleaved-Caspase-3/Caspase-3, GRP78, CHOP, p-IRE1α/IRE1α, p-ASK1/ASK1, and p-JNK/JNK expression showed significant increases (P<0.05, P<0.01). Compared with the model group, Liangfang Wenjing decoction intervention alleviated the symptoms of cold coagulation and blood stasis, gradually restored the estrus cycle, and improved ovarian histopathology and endothelial cell ultrastructure. Microcirculatory blood perfusion was significantly elevated (P<0.05). NO content in ovarian tissue was elevated, while ET-1, vWF, and TM levels were significantly decreased (P<0.05, P<0.01). The p-eNOS/eNOS ratio and Bcl-2 expression were significantly elevated (P<0.05), while the expression of Bax, cleaved-Caspase-3/Caspase-3, GRP78, CHOP, p-IRE1α/IRE1α, p-ASK1/ASK1, and p-JNK/JNK was significantly decreased (P<0.05, P<0.01). ConclusionLiangfang Wenjing decoction may regulate the IRE1α/ASK1/JNK signaling pathway to inhibit endoplasmic reticulum stress, attenuate apoptosis, and improve microvascular endothelial injury in ovaries of rats with cold coagulation and blood stasis syndrome.

A primary hallmark of pathological cardiac hypertrophy is excess protein synthesis due to enhanced translational activity. However, regulatory mechanisms at the translational level under cardiac stress remain poorly understood. Here we examined the translational regulations in a mouse cardiac hypertrophy model induced by transaortic constriction (TAC) and explored the conservative networks versus the translatome pattern in human dilated cardiomyopathy (DCM). The results showed that the heart weight to body weight ratio was significantly elevated, and the ejection fraction and fractional shortening significantly decreased 8 weeks after TAC. Puromycin incorporation assay showed that TAC significantly increased protein synthesis rate in the left ventricle. RNA-seq revealed 1,632 differentially expressed genes showing functional enrichment in pathways including extracellular matrix remodeling, metabolic processes, and signaling cascades associated with pathological cardiomyocyte growth. When combined with ribosome profiling analysis, we revealed that translation efficiency (TE) of 1,495 genes was enhanced, while the TE of 933 genes was inhibited following TAC. In DCM patients, 1,354 genes were upregulated versus 1,213 genes were downregulated at the translation level. Although the majority of the genes were not shared between mouse and human, we identified 93 genes, including Nos3, Kcnj8, Adcy4, Itpr1, Fasn, Scd1, etc., with highly conserved translational regulations. These genes were remarkably associated with myocardial function, signal transduction, and energy metabolism, particularly related to cGMP-PKG signaling and fatty acid metabolism. Motif analysis revealed enriched regulatory elements in the 5' untranslated regions (5'UTRs) of transcripts with differential TE, which exhibited strong cross-species sequence conservation. Our study revealed novel regulatory mechanisms at the translational level in cardiac hypertrophy and identified conserved translation-sensitive targets with potential applications to treat cardiac hypertrophy and heart failure in the clinic.

Fermented traditional Chinese medicine(TCM) has a long history of medicinal use, such as Sojae Semen Praeparatum, Arisaema Cum Bile, Pinelliae Rhizoma Fermentata, red yeast rice, and Jianqu. Fermentation technology was recorded in the earliest TCM work, Shen Nong's Classic of the Materia Medica. Microorganisms are essential components of the fermentation process. However, the contamination of fermented TCM by toxigenic fungi and mycotoxins due to unstandardized fermentation processes seriously affects the quality of TCM and poses a threat to the life and health of consumers. In this paper, the characteristics, microbial composition, and mycotoxin profile of fermented TCM are systematically summarized to provide a theoretical basis for its quality and safety control.

The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

A targeted metabolomics study was conducted on the bile acid profiles in the liver and feces of rats induced by a high-fat diet and intervened by ginsenoside Rb_1, along with the detection of FXR pathway gene expression in the liver, to explore and clarify its mechanism of action. The content of biochemical indicators in the serum were detected using an automatic biochemical analyzer. Hematoxylin and eosin(HE) staining and oil red O staining were used to detect pathological changes and lipid deposition in the liver. RT-PCR was used to detect the mRNA expression of FXR, small heterodimer partner(SHP), cholesterol 7 alpha-hydroxylase(CYP7A1), and sterol regulatory element-binding protein-1c(SREBP-1c) in the liver. Targeted bile acid metabolomics technology was employed to analyze changes in bile acid profiles in liver tissue and feces, and a correlation analysis was performed between key genes such as FXR, SHP, CYP7A1, SREBP-1c and differential bile acid metabolites. The results showed that ginsenoside Rb_1 significantly reduced the levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), and high-density lipoprotein cholesterol(HDL-C) in the serum, alleviated the large fat vacuoles and lipid deposition in the liver, increased the expression of FXR mRNA in the liver, and decreased the expression of SREBP-1c mRNA. The expression of CYP7A1 and SHP mRNA was increased, but the differences were not statistically significant. Targeted bile acid metabolomics showed that ginsenoside Rb_1 could restore the levels of 9 bile acids in the liver and 8 bile acids in the feces. Ginsenoside Rb_1 also increased the percentage of taurocholic acid(TCA) in the liver(56.78%) and the percentage of 12-ketolithocholic acid(12-KLCA) in the feces(26.10%). Pathway enrichment analysis revealed two pathways involved in bile acid metabolism: primary bile acid biosynthesis and taurine and hypotaurine metabolism. Correlation analysis showed that FXR, SHP, CYP7A1, and SREBP-1c were positively correlated with multiple differential bile acids. These results suggest that ginsenoside Rb_1 may intervene in lipid metabolism disorders induced by a high-fat diet by regulating the FXR pathway and modulating bile acid profiles in the liver and feces.
