Design and Development Strategies for Multicomponent Co-delivery System of Traditional Chinese Medicine / 中国实验方剂学杂志

Chinese materia medica has a wide range of clinical applications， but it has many active ingredients with different physicochemical properties， and the target organs， action pathways and mechanisms for different ingredients to exert their efficacy are not the same. Therefore， it is difficult to design and develop a co-delivery system loading multiple components of Chinese materia medica to maximize the synergistic therapeutic efficiency. Based on the characteristics of effectiveness and functionality of active ingredients， the strategies for multi-component co-delivery of Chinese materia medica can be categorized into two types：firstly， based on the effectiveness of active ingredients， new carriers such as liposomes， nanoparticles can be constructed to load multi-components of Chinese materia medica. secondly， based on the functionality of some active ingredients of Chinese materia medica， they are employed in the construction of co-delivery system， which can give play to the dual characteristics of their own efficacy and preparation functions. In this paper， we summarized the relevant research progress of the above two types of multi-component co-delivery strategies， and mainly discussed the pharmaceutical functions of the active ingredients in co-delivery systems， in order to find a more suitable multi-component co-delivery strategy， promoting the design and development of new delivery systems of Chinese materia medica.

The effect and mechanism of formononetin on alleviating no-reflow after myocardial ischemia and reperfusion by up-regulating the PI3K/Akt/eNOS signal pathway activated by GPER / 药学学报

To investigate the cardioprotective effect of formononetin (FMN) on no-reflow (NR) after myocardial ischemia-reperfusion and its molecular mechanism based on integrated pharmacology and experimental verification, firstly, human breast cancer MCF-7 cells and myocardial NR rats were used to confirm the estrogenic activity and the effect of alleviating NR of FMN, respectively. Male SD rats were divided into Sham, NR, FMN (20 mg·kg-1) and sodium nitroprusside (SNP, 5.0 mg·kg-1) groups, which were administered once a day for one week, the experiment was approved by the Ethics Committee of Tianjin University of Traditional Chinese Medicine (TCM-LAEC2019095). The pharmacological analysis and in vivo study of NR rats were integrated to reveal the mechanism of FMN improving NR. The results showed that FMN had estrogenic effect and reduced NR by improving cardiac structure and function, reducing NR, ischemic myocardial area and pathological injury of cardiomyocytes. Integrated pharmacology predicts that the mechanism of FMN improving NR is mainly related to phosphatidyinositol-3-kinase-protein kinase B (PI3K-Akt) signal pathway. Phytoestrogens play a role in cardiovascular protection mainly by activating G protein-coupled estrogen receptor (GPER). GPER is also an important regulator in the upstream of PI3K-Akt signaling pathway. This study found that FMN can significantly activate GPER, p-PI3K, p-Akt and phospho-endothelial nitric oxide synthase (p-eNOS). It has good binding ability with GPER and eNOS protein. In this study, through the integration of pharmacology and experimental evaluation, it is revealed that FMN activates PI3K/Akt/eNOS signal pathway by activating GPER, thus significantly improving NR.

Thoughts and Analysis on Regulating Tumor Pre-Metastatic Niche by Regulating Qi and Detoxifying / 中医杂志

Based on the concept of “imbalance of qi movement with the latent cancer toxin”， it is believed that the development process of tumor pre-metastatic niche （PMN） could be summarized as tumor derived secretory factors， exosomes and other “cancer toxin”， which latent in the body， were diffusion-prone by means of meridians and membrane-sources. Besides， the latent toxin induced the imbalance of qi movement， especially the distant weakest qi， and the local sweat pore and collateral vessels were blocked， which resulted in phlegm and blood stasis， and the cross-aggregation of poison. We also proposed therapeutic principles of PMN as first regulating qi and then clearing and expelling toxin， and tried to discuss the theoretical model of traditional Chinese medicine for PMN based on the theory of qi regulation and detoxification， aimed at providing ideas for the future theory construction of traditional Chinese medicine prevention and treatment for malignant tumor metastasis.

Research progress of the regulation effect of traditional Chinese medicine monomer of flavonoids on the pulmonary fibrosis signaling pathway / 中国药房

Pulmonary fibrosis is a chronic， progressive and irreversible interstitial lung disease. At present， there is no specific drug for the treatment of pulmonary fibrosis， and many TCM monomers have potential therapeutic value for pulmonary fibrosis， among which flavonoids are the main representative. For example， total flavones of Astragalus memeranaceus and scutellarin can reduce inflammatory cell infiltration， lung injury and extracellular matrix （ECM） deposition by interfering with transforming growth factor-β1/drosophila MAD protein signaling pathway. Total flavonoids of Oxytropis falcata Bunge and salidroside can inhibit lung inflammation by mediating JAK/signal transduction and transcriptional activator signaling pathway， and prevent the epithelial interstitial transition （EMT） process. Quercetin and Ginkgo biloba leaf extract can reduce the apoptosis of macrophages by inhibiting the nuclear factor-κB signaling pathway and play an anti-pulmonary fibrosis role. Urushetin and proanthocyanidins can promote the morphological recovery of myofibroblasts and reduce ECM deposition through the phosphatidylinositol 3-kinase/protein kinase B/mammalian target protein of rapamycin signaling pathway. Naringin and luteolin can inhibit scorch death of macrophage and inflammation response， and improve lung function and lung tissue injury through NOD-like receptor heat protein domain related protein 3 signaling pathway. The ethanol extract of Phyllanthus emblica and calycosin can improve the inflammatory injury and fibrosis of lung tissue by activating the signaling pathway of nuclear transcription factor erythro2-related factor 2/antioxidant response element. Isogliquiritin can inhibit the phenotypic transformation of epithelial cells and reverse EMT progression by inhibiting extracellular signal-regulating kinase signaling pathway. In the future， scholars should consider developing appropriate drug carriers to improve their bioavailability and further study drug targets and pathways， to provide evidence for the development of traditional Chinese medicine monomers of flavonoids into clinical practice.

Chemical reaction mechanism of decoction of traditional Chinese medicines: a review / 中国中药杂志

Complicated chemical reactions occur in the decoction of traditional Chinese medicines(TCMs) which features complex components, influencing the safety, efficacy, and quality controllability of TCMs. Therefore, it is particularly important to clarify the chemical reaction mechanism of TCMs in the decoction. This study summarized eight typical chemical reactions in the decoction of TCMs, such as substitution reaction, redox reaction, isomerization/stereoselective reaction, complexation, and supramolecular reaction. With the "toxicity attenuation and efficiency enhancement" of aconitines and other examples, this study reviewed the reactions in decoction of TCMs, which was expected to clarify the variation mechanisms of key chemical components in this process and to help guide medicine preparation and safe and rational use of medicine in clinical settings. The current main research methods for chemical reaction mechanisms of decoction of TCMs were also summed up and compared. The novel real-time analysis device of decoction system for TCMs was found to be efficient and simple without the pre-treatment of samples. This device provides a promising solution, which has great potential in quantity evaluation and control of TCMs. Moreover, it is expected to become a foundational and exemplary research tool, which can advance the research in this field.

Different effects of intravenous and local anesthesia in patients undergoing ultrasound-guided radiofrequency ablation of thyroid nodules: a prospective cohort study.

PURPOSE: To compare the efficacy and safety of intravenous anesthesia (IV) with local anesthesia (LA) in patients undergoing ultrasound (US)-guided radiofrequency ablation (RFA) of thyroid nodules. METHODS: 50 patients with American Society of Anesthesiologists classification grades I-II undergoing US-guided thyroid RFA were enrolled and randomly (1:1) divided into IV (conscious sedation with Ramsay Sedation Scale [RSS] scores of 2-3 with an anesthesiologist) and LA (subcutaneous anesthesia with lidocaine without an anesthesiologist) groups. Pre-, intra- and post-procedural blood pressure (BP) (SBP0/DBP0, SBP1/DBP1, and SBP2/DBP2), intra- and post-procedural pain (NRS1 and NRS2), ablated area volume, treatment time and adverse events were analyzed and compared. RESULTS: Age, sex, weight, number, nature, volume of nodules, and SBP0/DBP0 showed no difference between both groups. 11 and 0 patients' SBP1/DBP1 were elevated in the LA and IV groups. NRS1 differed between both groups. 6 patients in the LA group had moderate or severe pain, but none in the IV group. No between-group difference in SBP2/DBP2, NRS2, ablation completion rate and ablated volume was noted. The median procedure duration differed from 1109 (176) s in IV group and 723 (227) s in LA groups. There was no increased incidence of adverse events in IV group. CONCLUSIONS: IV with RSS scores of 2-3 maintained intra-procedural BP and relieved intra-procedural pain better, without affecting the ablation efficacy and increasing complications. Despite increased treatment time, IV is a potential option for patients undergoing US-guided RFA of thyroid nodules.

Regularity of prescriptions for intermediate and advanced lung cancer based on latent structure combined with association rules / 中国中药杂志

The present study explored the regularity of prescriptions for the treatment of intermediate and advanced lung cancer to provide references for clinical medication. CNKI, Wanfang, VIP, and CBM were searched for the research papers on the treatment of lung cancer by Chinese medicine published from database inception to May 31, 2021. The relevant information of qualified papers was extracted to establish a database. The Chinese medicines with frequency >3% underwent analysis of the latent structure and association rules by Lantern 5.0 and SPSS Molder 14.1, respectively, and the prescription regularity in the treatment of intermediate and advanced lung cancer was analyzed based on the frequency description. A total of 713 papers were included, involving 327 Chinese medicines with a cumulative frequency of 12 794 and 106 prescriptions with a cumulative frequency of 824. The commonly used Chinese medicines were dominated by deficiency-tonifying, heat-clearing, phlegm-resolving, and cough/dyspnea-relieving drugs, such as Astragali Radix, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Ophiopogonis Radix, Poria, and Hedyotis Diffusa, which are cold, warm, and plain in nature and sweet, bitter, and pungent in flavor, and mainly act on lung, spleen, and stomach meridians. Commonly used prescriptions included Shashen Maidong Decoction, Liujunzi Decoction, and Baihe Gujin Decoction. The latent structure analysis revealed 32 latent variables and 65 hidden classes. Six comprehensive clustering models and 11 core prescriptions were obtained by professional knowledge inference. The common syndromes of intermediate and advanced lung cancer were inferred to be Qi and Yin deficiency in the lung, Qi deficiency in the lung and spleen, Yin deficiency in the liver and kidney, combined phlegm and stasis, phlegm-heat obstructing lung, and Qi stagnation and blood stasis. Forty-four strong associations were screened out by association rules analysis, including four pairwise strong associations(Polygonati Odorati Rhizoma→Ophiopogonis Radix, Polygonati Odorati Rhizoma→Glehniae Radix, Amomi Fructus→Atractylodis Macrocephalae Rhizoma, and Polygonati Rhizoma→Astragali Radix) and 40 triplet strong associations(such as Trichosanthis Radix+Glehniae Radix→Ophiopogonis Radix, Polygonati Odorati Rhizoma+Glehniae Radix→Ophiopogonis Radix, Trichosanthis Radix+Ophiopogonis Radix→Glehniae Radix, and Scutellariae Barbatae Herba+Codonopsis Radix→Hedyotis Diffusa). In the treatment of intermediate and advanced lung cancer, Qi-replenishing and Yin-nourishing drugs are mainly employed, assisted with cancer-resisting, toxin-removing, spleen-invigorating, phlegm/stasis-resolving, and blood-activating drugs based on syndrome differentiation. The roots were treated following the principles of tonifying lungs and replenishing the spleen, and symptoms following the principles of removing the toxin, dispelling stasis, and resolving phlegm.

Collagen derived species-specific peptides for distinguishing donkey-hide gelatin (Asini Corii Colla) / 中草药·英文版

Objective: As an important food therapy product with traditional Chinese medicine (TCM) applications, donkey-hide gelatin (Asini Corii Colla, ACC) has been used for thousands of years. However, till now few effective strategy had been proposed to distinguish ACC from other animal hide gelatins, especially closely related horse- and mule-hide gelatins, which was an embarrassment of ACC quality control. Methods: Combined mass spectrometry and bioinformatic methods have been applied to identify and verify two ACC-specific peptides (Pep-1 and Pep-2) capable of distinguishing ACC from other closely related animal gelatins with high selectivity. Results: It confirmed that these two peptides could be not only used for distinguishing ACC from highly homologous horse-hide and mule-hide gelatins as well as other animal hide gelatins. Conclusion: The present study provides a simple method for species-specific peptides discovery, which can be used for assessing the quality of animal gelatin products, and ensure they are authenticable and traceable.

Nucleic acid aptamer-based traditional Chinese medicine application:therapy,targeting and diagnosis / 中国中药杂志

Nucleic acid aptamers, broad-spectrum target-specific single-stranded oligonucleotides, serve as molecules in targeted therapy, targeted delivery and disease diagnosis for the treatment of tumor or microbial infection and clinical detection. Due to the existence of components in the use of traditional Chinese medicine(TCM), the target is difficult to concentrate and the specificity of treatment is poor. The effective components of TCM are toxic components, so a highly sensitive detection method is urgently needed to reduce the toxicity problem at the same time. The combined application of TCM and modern medical treatment strategy are difficult and cannot improve the therapeutic effect. Aptamers, advantageous in biosensors, aptamer-nanoparticles for targeted drug delivery, and aptamer-siRNA chimeras, are expected to connect Chinese medicinals with nanotechnology, diagnostic technology and combined therapies. We summarized the preparation, screening, and modification techniques of nucleic acid aptamers and the biomedical applications and advantages in therapy, targeting, and diagnosis, aiming at providing a reference for the in-depth research and development in TCM.

Effect of different parts of Pinelliae Rhizoma Decoction against airway inflammation and analysis of effective components / 中国中药杂志

This study investigated the material basis and mechanism of Pinelliae Rhizoma Decoction in the treatment of airway inflammation. The cigarette smoke combined with lipopolysaccharide(LPS) was used to induce an airway inflammation model in mice. The expression levels of IL-6 and IL-8 in the bronchoalveolar lavage fluid(BALF) and the phosphorylation levels of p38 and IκB in the lungs of mice were taken as indexes to screen the effective extracts by system solvent extraction from Pinelliae Rhizoma Decoction(dichloromethane extract, ethyl acetate extract, n-butanol extract, etc.). Meanwhile, the human bronchial epithelial(16-HBE) cell model of cigarette smoke extract(CSE)-induced injury was established, and the mRNA expression levels of IL-6 and IL-8 and the phosphorylation levels of p38 and IκB proteins were also taken as indexes to evaluate the anti-inflammatory effect of different extracts of Pinelliae Rhizoma Decoction. The results showed that Pinelliae Rhizoma Decoction significantly antagonized airway inflammation in mice by down-regulating the expression levels of IL-6 and IL-8 in mice with airway inflammation and 16-HBE cells with CSE-induced injury and inhibiting the phosphorylation levels of p38 and IκB. The dichloromethane and ethyl acetate extracts of Pinelliae Rhizoma Decoction showed significant anti-inflammatory effects, while such effects of other extracts were not prominent. Furthermore, the database of Pinelliae Rhizoma composition was constructed, and the components in effective extracts were analyzed by HPLC-TOF-MS and Nano-LC-MS/MS. As revealed by the results, the compositions of the two effective extracts were similar with 36 common components. They were combined and then divided into Pinelliae Rhizoma alkaloids(PTAs) and Pinelliae Rhizoma non-alkaloids(PTNAs) by 732 cation-exchange resin. Further in vitro investigation confirmed the significant anti-inflammatory effect of PTNAs, while such effect of PTAs was not manifest. The MS analysis showed 172 peptides and 7 organic acids in PTNAs. The peptide content in PTNAs was 63.5% measured by quantitative analysis of BCA assay, and the organic acid content was 9.92% by potentiometric titration method. The findings of this study suggested that Pinelliae Rhizoma Decoction could antagonize airway inflammation in mice by inhibiting phosphorylation of p38 and IκB and blocking the activation of MAPK and NF-κB signaling pathways, and the effective components were related to the peptides and organic acids in PTNAs. The above results lay a foundation for the research on the mechanism and material basis of Pinelliae Rhizoma in antagonizing airway inflammation.

[Biological research of color and quality evaluation in "quality discrimination by character" of Chinese medicine].

In the theories of empirical identification of "arguments on quality" and "five elephants and seven originals", color is regarded as one of the important indicators in the quality evaluation of Chinese medicine. The color of medicinal material including the surface color, the internal color, and the color after processing is caused by the pigment in the cells, which is a characteristic of the "optimal shape". Most pigments have a wide range of pharmacological activities such as anti-oxidation, anti-tumor, anti-atherosclerosis, prevention of coronary heart disease, protection of cardiovascular function, enhancement of immunity, etc. Therefore, the "optimal color" of medicinal materials is unified with the "high quality". This article systematically reviews the research status of "quality discrimination by color", the correlation between L~*, a~*, b~* color space and active ingredients such as alkaloids, flavonoids, terpenes, etc. to explain the "quality discrimination by color" in quantitative characterization. We also summary the research progress on the biosynthesis and regulation of the main pigment components of traditional Chinese medicine, and analyze the biological causes that affect the accumulation of the main pigments. We aim to provide a reference for the theory "quality discrimination by color" in biological knowledge to establish a modern quality control system for Chinese herbal medicines.

Proteomics and peptidomics analysis of Sepiae Endoconcha / 中国中药杂志

Shotgun based proteomics and peptidomics analysis were used to investigate the proteins and peptides in marine traditional Chinese medicine(TCM) Sepiae Endoconcha(cuttlebone). Peptides were extracted from cuttlebone by acidified methanol, and then strong cation exchange(SCX) resin was used to enrich those peptides. Also, proteins from cuttlebone were extracted and digested by trypsin. nano-LC Q Exactive Orbitrap mass spectrometry was used to analyze proteins and peptides from cuttlebone. As a result, a total of 16 proteins and 168 peptides were identified by protein database search, and 328 peptides were identified by De novo sequencing. The identified proteins were hemocyanin, enolase, myosin, actin, calmodulin, etc., and the identified peptides were derived from actin, histone, and tubulin. All these proteins and peptides were important components in cuttlebone, which would provide important theoretical and research basis for marine TCM cuttlebone investigations.

Ideas and strategies for investigating the bioactive constituents of animal derived traditional Chinese medicines based on integrated "proteomics/peptidomics-modifications" methods / 药学学报

Animal derived traditional Chinese medicines (ATCMs) are an important part of traditional Chinese medicine (TCM). The lack of proper ideas and strategies made it not systematic and perfect enough on investigating bioactive components and quality evaluation of ATCMs, which restrict many aspects of ATCMs investigation including clinical applications, pharmaceutical technologies, and quality control. Therefore, based on our previous investigations of animal horn and animal derived gelatin TCMs, and the research progress at home and abroad, ideas and strategies for investigating the correlations between proteins/peptides and their bioactivities in animal horn and animal gelatin derived TCMs based on integrated "proteomics/peptidomics-modifications" methods was proposed. Firstly, proteomics and peptidomics analysis can be used to study proteins and peptides in ATCMs. Secondly, modification analysis can be used to reveal those chemical modifications on proteins and peptides of ATCMs. Thirdly, the correlations between components, modifications and traditional bioactivities can be systemic discussed. Based on the present study, hopefully, enough evidences and reference can be provided to resolve the issues in ATCMs investigations on modernization and bioactive material basis.

Hypophosphatemic osteomalacia caused by urinary mesenchymal tumor: A case report / 北京大学学报(医学版)

This case report concerns a 34-year-old woman who had been diagnosed with ankylosing spondylitis (AS), fibromyalgia syndrome (FMS), osteoarthritis (OA), lumbar disc herniation and the like in different hospitals during the past 18 months. She had progressive osteoarthrosis, significant muscle weakness, gait abnormalities in weightbearing areas, however without typical inflammatory low back pain, while the treatment with non-steroidal anti-inflammatory drugs (NSAIDs) was invalid, with normal inflammation index, negative results for rheumatic factor (RF) and human leukocyte antigen (HLA)-B27, and normal erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). She had hyphosphatemia, normal serum calcium, 1,25-(OH)2-D3 reduction, elevated alkaline phosphatase (ALP) and normal parathyroid hormone (PTH), however with elevated urinary phosphorus. Finally, the medial thigh nodule was found in the subcutaneous of her inner leg by careful examination and imaging scans including B-ultrasound and PET/CT. The final pathology confirmed that the nodule was phosphate urinary mesenchymal tumors. After the tumor was removed, the patient was treated with anti-osteoporosis and phosphorus supplementation. The symptoms of bone pain and muscle weakness were alleviated, and hypophosphatemia was corrected. It was confirmed that the patient had low-phosphorus osteomalacia due to tumor. Tumor-induced hypophosphatemia osteomalacia (TIO) was a rare paraneoplastic syndrome which was caused by excessive phosphorus excretion induced by the tumor, and was thus categorized as an acquired hypophosphatemic osteomalacia. TIO had an occult onset and was associated with a high rate of misdiagnosis, although TIO has some typical clinical features. Early diagnosis, correctly positioning of the tumor, and surgical resection can achieve good outcomes.

Determination of free thiols in animal horn derived traditional Chinese medicines / 中国中药杂志

This present study is to detect the content of free thiols(-SH) in the horn derived traditional Chinese medicines( TCMs) from different animals and different regions by using fluorescence derivatization method. TCEP was used as a disulfide bond reducing agent,while SBD-F as a derivatization reagent. Fluorescent spectrophotometry was used to determine the content of-SH,and the maximum excitation wavelength and emission wavelength were set as 375 and 510 nm,respectively. As a result,under the optimized condition,the extraction of Caprae Hircus Cornu showed the highest free-SH concentration,followed by Bovis Grunniens Cornu,Bubali Cornu,and Elaphuri Davidiani Cornu. In the present study,we point out that the-SH-contained components might be the most important material basis in animal horn derived TCMs. With good accurate,sensitive and rapid properties,the present method can provide reference basis for the quality evaluation of animal horn derived TCMs and guides for the investigation on effective material basis.

Research progress on Curcumae Radix and its near-source species and predictive analysis on Q-marker / 中草药

Curcuma Radix is a kind of multi-base crude drug, which is originated from Curcuma genus same as Curcuma longa, Curcumae Rhizoma, and Wenyujin Rhizoma Concisum. There are original overlapping parts among them, but in the part of medicine and the processing method are different.
