[Composition and morphology of Scutellariae Radix-Coptidis Rhizoma decoction co-precipitate and effect on in vivo behavior of decocting liquid].

Scutellariae Radix-Coptidis Rhizoma(SR-CR) herbal pair is commonly used in many compound prescriptions for their synergistic heat-clearing and dampness-drying properties. During the decoction process, a substantial amount of precipitate is generated. However, there have been no explicit reports on the composition, morphology, and potential effects of this precipitate on the in vivo behavior of SR-CR decoction. This study employed high-performance liquid chromatography(HPLC), high-resolution mass spectrometry, and other techniques to analyze the composition of the co-precipitate in the decoction of SR-CR. Scanning electron microscopy and mass spectrometry imaging were used to analyze its appearance and morphology. Additionally, rats were used to investigate the effects of the co-precipitate on the in vivo behavior of the main components in the SR-CR decoction. The research findings indicated that eight components, including coptisine, berberine, epiberberine, palmatine, baicalin, oroxylin A-7-O-ß-D-glucuronide, wogonoside and baicalein, constituted the primary composition of the co-precipitate. Among these, baicalin and berberine hydrochloride were the most abundant, accounting for about 60% of the total weight. Moreover, the co-precipitate contained 18% tannins. Morphological analysis revealed that the particles in the SR-CR decoction precipitate were spherical microparticles with an average diameter of around 600 nm. Pharmacokinetic research demonstrated that there were significant differences in the AUC, C_(max), t_(1/2), and T_(max) of baicalin, a major component, in rats administered with lyophilized powders of the combined decoction and single decoctions of SR-CR orally, suggesting that the precipitate generated during the decoction process can affect the in vivo behavior of the main components of the SR-CR decoction. It can reduce the absorption of baicalin in the body, decrease the extent of rapid drug release, and to a certain extent, prevent adverse reactions or side effects.

Effects of Multi-Dimensional Nursing Based on HAPA Theory on Self-Care Ability and Cardiac Function in Patients with Coronary Heart Failure and Heart Failure.

Objective: This study aimed to investigate the effects of multi-dimensional nursing based on the Health Action Process Approach (HAPA) theory on self-care ability and cardiac function in patients with coronary heart disease (CHD) and heart failure. To explore the effects of multi-dimensional nursing based on the health action process approach (HAPA) theory on self-care ability and cardiac function in patients with coronary heart disease (CHD) and heart failure. Methods: A total of 94 patients with CHD and heart failure admitted to the hospital were enrolled between January 2021 and October 2022. The random number table method divided them into a control group (47 cases, routine nursing in cardiology department) and observation group (47 cases, multi-dimensional nursing based on HAPA theory, which is a mental model used to explain and predict the health behavior of individuals). Before and after the intervention, self-care ability, negative emotions, cardiac function and quality of life in both groups were evaluated by the exercise of self-care agency scale (ESCA), self-rating anxiety scale (SAS), self-rating depression scale (SDS), 6-minute walking test, left ventricular ejection fraction (LVEF) and Minnesota living with heart failure questionnaire (MLWHFQ). Results: During the study period, at discharge, self-care ability in both groups was improved, which was better in the observation group than the control group (P < .05). At discharge, SAS and SDS scores in both groups were decreased, which were lower in the observation group than control group (P < .05). At 6 weeks after discharge, cardiac function (LVEF, 6 min walking distance) in both groups was improved, and the improvement effect was better in the observation group than control group (P < .05). There was no significant difference in the quality of life at discharge and 6 weeks after discharge in the observation group (P > .05), but it was worse in the control group at 6 weeks after discharge (P < .05). Conclusions: Multi-dimensional nursing based on HAPA theory can significantly improve self-care ability, improve cardiac function, and quality of life in patients with CHD and heart failure.

Omega-3 Polyunsaturated Fatty Acids Protect Neurological Function After Traumatic Brain Injury by Suppressing Microglial Transformation to the Proinflammatory Phenotype and Activating Exosomal NGF/TrkA Signaling.

The transformation of microglia to a pro-inflammatory phenotype at the site of traumatic brain injury (TBI) drives the progression of secondary neurodegeneration and irreversible neurological impairment. Omega-3 polyunsaturated fatty acids (PUFA) have been shown to suppress this phenotype transformation, thereby reducing neuroinflammation following TBI, but the molecular mechanisms are unknown. We found that Omega-3 PUFA suppressed the expression of disintegrin metalloproteinase (ADAM17), the enzyme required to convert tumor necrosis factor-α (TNF-α) to the soluble form, thereby inhibiting the TNF-α/NF-κB pathway both in vitro and in a mouse model of TBI. Omega-3 PUFA also prevented the reactive transformation of microglia and promoted the secretion of microglial exosomes containing nerve growth factor (NGF), activating the neuroprotective NGF/TrkA pathway both in culture and TBI model mice. Moreover, Omega-3 PUFA suppressed the pro-apoptotic NGF/P75NTR pathway at the TBI site and reduced apoptotic neuronal death, brain edema, and disruption of the blood-brain barrier. Finally, Omega-3 PUFA preserved sensory and motor function as assessed by two broad-spectrum test batteries. The beneficial effects of Omega-3 PUFA were blocked by an ADAM17 promotor and by a NGF inhibitor, confirming the pathogenic function of ADAM17 and the central neuroprotective role of NGF. Collectively, these findings provide a strong experimental basis for Omega-3 PUFA as a potential clinical treatment for TBI.

Exploring the target and molecular mechanism of Astragalus membranaceus in the treatment of vascular cognitive impairment based on network pharmacology and molecular docking.

Astragalus membranaceus (AM) is a traditional Chinese herbal medicine extensively utilized in vascular cognitive impairment (VCI) treatment. However, due to the complex components of AM, its exact molecular mechanism remains unclear. Therefore, this study investigated the target and molecular mechanism of AM to treat VCI based on network pharmacology and molecular docking. Firstly, the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, STITCH, and SwissTargetPrediction were utilized to gather the primary active ingredients of AM. The potential therapeutic targets of VCI were collected through GeneCards, OMIM, and DisGeNET databases. Secondly, the protein-protein interaction network was built using the STRING database. The enrichment analysis of gene ontology and the Kyoto Encyclopedia of Genes and Genome pathways was carried out in the R language. Finally, The network topology calculation of Cytoscape software was combined with module analysis to predict the binding properties of its active ingredients and targets. Twenty effective compounds and 733 targets were screened from AM, among which 158 targets were seen as possible targets of AM to treat VCI. MAPK3 and MMP9 were the critical targets of AM intervention in VCI. The crucial pathways include PI3K/Akt, MAPK, Rap1, and Ras signaling pathways. Besides, calycosin and quercetin might be the potential active compounds of AM for VCI treatment. AM intervenes in VCI through a multi-ingredient, multi-target, and multi-pathway coordination mechanism. These findings provide a foundation for a deeper understanding of the molecular mechanisms by which AM is effective in treating VCI.

Traditional Chinese Medicine (TCM) exerts anti-tumor effects by intervening in A549 cells of human lung adenocarcinoma, mainly including activating or inhibiting downstream target proteins of Bcl-2 and Bax, or forming RIP1/RIP3/MLKL complex bodies by affecting pathways such as PI3K/Akt, thereby inducing apoptosis in A549 cells of lung adenocarcinoma; blocks the cell growth phase, thereby inhibiting the proliferation of lung adenocarcinoma A549 cells; inhibits invasion and metastasis of A549 cells by affecting the MMPs pathway, STAT3 pathway, and regulating epithelial mesenchymal transition related factors; suppresses or activates the expression of related proteins or affect related signaling pathways, thereby reversing the resistance of lung cancer A549/DDP cell lines to cisplatin and paclitaxel.

MDSCs Aggravate the Asthmatic Progression in Children and OVA-Allergic Mice by Regulating the Th1/Th2/Th17 Responses.

Background: Asthma is a chronic inflammatory disease of respiratory with serious risks for children. This study explored myeloid-derived suppressor cells (MDSCs) on the pathogenesis of asthmatic children and mice. Methods: The clinical study enrolled 30 asthma, 20 pneumonia, and 20 control participants. The MDSCs, Th17 and Th1 cells percentage, and IL-4, IL-12, IL-10, and IFN-γ levels were detected by flow cytometry and ELISA. In experimental asthma, mice were divided into control, ovalbumin (OVA), and OVA + MDSCs groups. The changes in inflammatory cell count and the levels of IL-5, IL-12, and IL-10 in mice BALF and the levels of inflammatory factors, IgE, and IFN-γ in mice were detected by ELISA. The amount of ROS generation and pathological changes and the levels of caspase 1 and caspase 3 were tested by flow cytometry, HE and PAS staining, and immunohistochemistry. The expression of cleaved caspase 1/caspase 1 and cleaved caspase 3/caspase 3 was detected by western blot. Results: In clinical trials, the levels of IL-12, IFN-γ, and Th1 percentage decreased in pneumonia and asthma children's peripheral blood, while the levels of IL-4 and IL-10 and the percentages MDSCs and Th17 increased. In asthma mice, pathological staining showed that asthma caused lung inflammation and damage, while the OVA + MDSC group was severer. Moreover, the percentages of eosinophils, neutrophils, lymphocytes, and the levels of inflammatory factors, IgE, ROS production, caspase 1, caspase 3, cleaved caspase 1/caspase 1, and cleaved caspase 3/caspase 3 increased in OVA + MDSC group, while the percentage of macrophages, IL-12, and IFN-γ levels reduced, illustrating that MDSCs exacerbated asthma. Conclusion: Our study indicated that MDSCs could aggravate asthma by regulating the Th1/Th2/Th17 response.

Protective Effects of Platycodin D3 on Airway Remodeling and Inflammation via Modulating MAPK/NF-κB Signaling Pathway in Asthma Mice.

Background: Asthma is a disease with airway hyperresponsive and airway inflammation. Platycodin D is a triterpenoid saponin extracted from Platycodon grandiflorus root, which has various pharmacological activities. The study mainly explored the effects of platycodin D3 (PD3) in airway remodeling and inflammation of asthma. Methods: The ovalbumin (OVA)-induced asthma mice were given PD3 (20 mg/kg, 40 mg/kg, and 80 mg/kg) in different groups. The asthma mice administrated with dexamethasone (DXM) were enrolled as the positive control group, and the normal control mice and asthma model mice separately received the same volume of saline. Mouse airway lung dynamic compliance (Cdyn) and total airway resistance (RL) were measured by the EMKA animal lung function analysis system. The inflammation factor levels were estimated by ELISA. Histopathological changes were tested by HE and PAS staining. The protein and phosphorylation levels of NF-κBp65, p38, ERK1/2, and JNK1/2 were detected by Western blot. Results: In asthmatic mice, PD3 enhanced the airway Cdyn and decreased RL to improve the airway hyperreactivity and alleviated the pathological injury of lung tissues. In addition, PD3 could reduce the infiltration of inflammatory cells in BALF and suppress the levels of eotaxin, IL-4, IL-5, IL-13, IFN-γ, and IgE. Furthermore, PD3 treatment inhibited the phosphorylation of NF-κBp65, p38, ERK1/2, and JNK1/2 proteins in asthma mice. Conclusion: PD3 treatment alleviated the airway remodeling and inflammation in asthmatic mice, which might be related to downregulating the phosphorylated proteins in the MAPK/NF-κB signaling pathway.

Expression of astrocyte-elevated gene-1 indicates prognostic value of fluoropyrimidine-based adjuvant chemotherapy in resectable stage III colorectal cancer.

It is unclear which prognostic factor such as pathological features and gene mutation are majorly relevant for stage III disease and whether they aid in determining patients who will be benefit from postoperative adjuvant chemotherapy. The expression of astrocyte-elevated gene-1 (AEG-1), thymidylate synthase (TS), excision repair cross-complementation group 1 (ERCC1), epidermal growth factor receptor (EGFR), and vascular endothelial growth factor (VEGF) was examined to investigate their role in adjuvant chemotherapy for patients with resectable stage III colorectal cancer (CRC). A significant positive correlation was observed between AEG-1, TS, ERCC1, EGFR, and VEGF gene expression levels in CRC cell lines, and low AEG-1 and TS expression were highly sensitive to 5-fluorouracil treatment. Our results showed that AEG-1 expression was high in T4 and caused CRC recurrence or metastasis. Patients with T4, high AEG-1, TS and VEGF expression had a significantly short disease-free survival and overall survival. In multivariate Cox regression analysis, high AEG-1 expression could be an independent prognostic factor indicating poor survival in patients with resectable stage III CRC treated with adjuvant chemotherapy. In conclusion, AEG-1 expression and tumor grade are potential prognostic factors for recurrence and survival in patients with stage III CRC receiving adjuvant fluoropyrimidine-based chemotherapy.

Study on the Effect of Antiplatelet and Gastric Mucosal Protection of Traditional Chinese Medicine Invigorating Qi and Hemostasis.

BACKGROUND: To investigate the effects of Chinese herbal medicine in tonifying qi and attaining hemostasis caused by the metabolism of the drug clopidogrel and as a result of platelet and gastric mucosa injury in an ischemia-reperfusion rat model. METHODS: A pharmacokinetic model was established to record the drug metabolism parameters of clopidogrel metabolites. Then, absorption of the drug was compared with approaches using the traditional Chinese medicine (TCM) approach of tonifying qi and establishing hemostasis, to using the drug pantoprazole and applying these approaches in combination with clopidogrel. Intragastric administration was performed, and all indicators were tested. RESULTS: The area under the curve (AUC; 0-T, 300.342 ± 35.832 mg/L* h; AUC 0-∞, 320.462 ± 40.213 mg/L* h), the plasma peak concentration (30.622 ± 9.917 mg/L*), and the peak time and half-life (7.954 ± 1.121 h) in the clopidogrel and the TCM groups were higher than those in the clopidogrel and pantoprazole groups. In terms of antiplatelet aggregation, compared with model group, the platelet aggregation rate induced by arachidonic acid (AA) and adenosine diphosphate (ADP) was significantly decreased by the TCM approach of tonifying qi and stopping bleeding (p < 0.05). The ADP, thromboxane A2, GPII B/Pa-A, CD62P and platelet factor 4 content in the TCM yiqi decoction and hemostasis approach were significantly decreased (p < 0.01). Compared with the clopidogrel group, the gastrin and motilin in the serum, the cyclooxygenase (COX)-1 and prostaglandin E2 in gastric tissue, and expression of vascular endothelial growth factor messenger ribonucleic acid in the serum were all significantly increased using TCM approach to protect against gastric mucosal injury (p < 0.05). CONCLUSION: TCM invigorating qi and hemostasis has an inhibitory effect on platelet activation. It can reduce the local inflammatory reaction at the same time as protecting gastric mucosa.

[GC-MS analysis of volatile oil components of Mastiche and Olibanum and study on antibacterial activity of Helicobacter pylori].

The volatile oil from Mastiche and Olibanum medicinal materials was extracted by steam distillation, and the chemical components of the volatile oil were analyzed by GC-MS technology. The differences of the volatile oil components were compared and study on the Helicobacter pylori in vitro antimicrobial activitiy was conducted. The results showed that the yields of the volatile oil from Mastiche and Olibanum were 11.93% and 2.40%, respectively. A total of 46 compounds(91.31%) were identified from the volatile oil from Mastiche annd 35 compounds(92.49%) from Olibanum. The classification and comparison study of the components showed that the content of monoterpenes in the volatile oil from Mastiche was the highest(40.69%), followed by alcohols(28.48%); while the content of alcohols in the volatile oil from Olibanum was the highest(35.81%), followed by esters(24.92%). There were significant differences in the components of volatile oil from Mastiche and Olibanum, which might be one of the reasons for the difference in efficacy and application. In vitro bacteriostatic experiments showed that the minimum inhibitory concentration(MIC) of the volatile oil from Mastiche against H. pylori was 1 mg·mL~(-1), and the MIC of the volatile oil from Olibanum against H. pylori was more than 1 mg·mL~(-1). In combination with the results of the oil yield experiment, Mastiche had the advantage of inhibiting H. pylori activity. The research results provide scientific basis for the rational application of Mastiche and Olibanum.

Traditional medicinal knowledge in Lancang-Mekong River:a case study in Lancang Lahu autonomous county / 中国中药杂志

Lancang Lahu autonomous county, where the Lancang-Mekong River flows by, was selected as the case site to investigate the traditional medicinal knowledge(TMK). A comparison of TMK between Lancang county and other places in the Lancang-Mekong sub-region was conducted. Research on TMK has been seldom reported although there are abundant medicinal resources in this sub-region. The key informant interview and other methods have been adopted in the field surveys in the past six years. The investigation revealed that there was rich TMK and various herbal medicine resources in Lancang county. A total of 220 folk prescriptions have been collected, which were normally simple with easy processing methods and usages, and most raw materials were freshly used. As for medicinal plants, 121 species in 67 families have been documented. Other findings included that TMK in Lancang county was remained at the level of medication based on experience only. The processing methods of herbal medicines were simple and the bioactive ingredients were not clear. Without text and cultural support for self-teaching, coupled with conservative inheritance, it resulted in massive losses of TMK. The folk doctors have accumulated their factions based on self-study or ancestral experience. There was different treatment experience among folk doctors, but the safety and effectiveness should be paid attention to. The folk doctors used various herbal medicines, but there was a lack of standards or specifications for quality control. Given the problems existing in inheritance and development, conservation strategies were proposed in the present study.

CONCLUSIONS: Massage therapy is beneficial for preterm infant weight gain.

[Rheology and in vitro release properties of thermosensitive in situ gel of Yihuang Decoction and its common gel for vaginal use].

To evaluate the traits and rheological properties of thermosensitive in situ gel of Yihuang Decoction and its common gel for vaginal use, and predict the release behavior of Yihuang Decoction in situ gel in vitro. Poloxamer was used as thermosensitive material to prepare Yihuang Decoction vaginal in situ gel, and Yihuang Decoction common gel was prepared with carbopol. Then the differences of the two gels before and after diluting with vaginal fluid were compared. The rheological parameters of Yihuang Decoction in situ gel and its common gel were determined with Anton Paar MCR102 rheometer. In addition, berberine hydrochloride was selected as an index component to evaluate the in vitro release properties of Yihuang Decoction vaginal thermosensitive in situ gel. Yihuang Decoction vaginal thermosensitive in situ gel was Newtonian fluid under low-temperature conditions, which was yellow and transparent. After reaching the gelling temperature of 24.5 ℃, it became semi-solid, pseudoplastic fluid. The gelling temperature was predicted to be 37 ℃, and the phase transition time was 30 s after diluting with simulated vaginal fluid. However, the rheological properties of Yihuang Decoction common gel had no significant changes with temperature. Compared with in situ gel, the color of common gel was darker and more translucent. Besides, its mobility was stronger after diluting with simulated vaginal fluid. The in vitro release study showed that the kinetic behavior of berberine hydrochloride in Yihuang Decoction vaginal thermosensitive in situ gel was matched with the Higuchi equation. Through simulation of vaginal administration, physical properties and dynamic rheological parameters were used to intuitively and scientifically evaluate the two gels. Compared with the common gel, the thermosensitive in situ gel could quickly attached to the vaginal mucosa and release drug, and thus was more suitable for developing vaginal administration of Yihuang Decoction, which also provides references for studying new vaginal preparation of Yihuang Decoction.

An Efficient Strategy for Enhancement of Bioactive Compounds in the Fruit Body of Caterpillar Medicinal Mushroom, Cordyceps militaris (Ascomycetes), by Spraying Biotic Elicitors.

Cordyceps militaris is a mushroom species with high nutritive and medicinal values based on diverse bioactive metabolites. The contents of bioactive ingredients are indicative of the quality of commercially available fruit body of this fungus. Although the application of biotic elicitors has been an efficient strategy to induce the accumulation of valuable bioactive compounds in vivo, related research in C. militaris is rarely reported. In this study, five biotic elicitors in different concentrations (0.05, 0.5, 1, and 2 mg/mL), including chitosan (CHT), 2,4-dichlorophenoxyacetic acid (2,4-D), methyl jasmonate (MeJA), gibberellic acid (GA), and triacontanol (TRIA), were first introduced to enhance the production of 10 kinds of major bioactive components in the fruit body of C. militaris. Results showed that the effect of biotic elicitors on bioactive compounds in the fruit body of C. militaris was elicitor-specific and concentration-dependent. Overall, 1 mg/L CHT was considered the most favorable for the production of 10 bioactive ingredients in C. militaris fruit body, which could increase the content of protein, polysaccharides, polyphenol, triterpenoids, flavonoids, cordyceps acid, cordycepin, and anthocyanins by 20.38-, 1.41-, 0.7-, 0.47-, 11.90-, 1.09-, 0.34-, and 2.64-fold, respectively, compared with the control. The results of this study would provide an efficient strategy for the production of a superior quality fruit body of and contribute to further elucidation of the effects of biotic elicitors on metabolite accumulation in C. militaris.

Enhanced biomethane recovery from fat, oil, and grease through co-digestion with food waste and addition of conductive materials.

In this study, the effect of conductive additives on co-digestion of fat, oil, and grease (FOG) and food waste (FW) was evaluated. Initially, biochemical methane potential (BMP) test was conducted for optimization of mixing ratio of FW and FOG. The optimal methane production (800 L (kg VS)-1) was obtained from co-digestion of 70% FW + 30% FOG (w/w), which was 1.2 times and 12 times of that obtained from mono-digestion of FW and FOG, respectively. This optimal mixing ratio was used for subsequent fed-batch studies with the addition of two conductive additives, granular activated carbon (GAC) and magnetite. The addition of GAC significantly shortened the lag phase (from 7 to 3 d), reduced accumulation of various volatile fatty acids (VFAs), and enhanced methane production rate (50-80% increase) compared to the control and magnetite-amended bioreactor. Fourier transformation infrared (FTIR) analysis suggested that the degradation of lipids, protein and carbohydrates was the highest in GAC amended reactor, followed by magnetite and control reactors. GAC addition also enriched more abundant and diverse bacteria and methanogens than control. Magnetite addition also showed similar trends but to a lesser degree. The substantial enrichment of syntrophic LCFA ß-oxidizing bacteria (e.g. Syntrophomonas) and methanogenic archaea in the GAC-amended bioreactor likely attributed to the superior methanogenesis kinetics in GAC amended bioreactor. Our findings suggest that the addition of GAC could provide a sustainable strategy to enrich kinetically efficient syntrophic microbiome to favor methanogenesis kinetics in co-digestion of FW and FOG.
