    Effectiveness of fermentation broth of Cordyceps sinensis for primary insomnia: a randomized clinical trial with digital health tool

    by Shuting Zhao, Ziqian Wang, Xiaxia Fan, Xuanhao Shu, Qiao Chen, Yibo Zhou, Yongzhi Fu, Zheng Yu, Marcin Grzegorzek, Xinyu Huang, et al.

    Background: Cordyceps sinensis is widely used in Traditional Chinese Medicine and dietary supplements to tonify the kidney, lung, and heart, as well as to calm the mind. The fermentation broth of Cordyceps sinensis (FBCS), containing cordycepin, has shown potential in various healthcare applications.Methods: Ninety patients with primary insomnia were divided into two groups: the FBCS group (n = 45) and the control group (n = 45). The FBCS group received Cordyceps fermentation liquid drink (150 ml/day), while the control group received a placebo (150 ml/day). Both groups were supported by Digital Health Tools (DHT) for medication supervision. Pittsburgh Sleep Quality Index (PSQI) scores were assessed and collected through the DHT application at the initial baseline period, 14, and 28 days after treatment.Results: Significant main effects of time and time × group interaction on the PSQI total score and all subcomponents. Significant group effects were also observed for most subcomponents, except for Sleep Disturbances and Daytime Function, indicating greater improvements in the FBCS group over time. After 14 and 28 days of FBCS consumption, the treatment group demonstrated greater reductions in PSQI total scores compared to the control group. Subcomponent analysis revealed greater improvements in the FBCS group compared to the control group at both time points. Specifically, Sleep Quality scores decreased by −0.89 vs. −0.50 at Day 14 and −1.32 vs. −0.45 at Day 28. Sleep Onset Latency improved by −0.75 vs. −0.20 at Day 14 and −1.32 vs. −0.27 at Day 28. Sleep Duration scores decreased by −0.86 vs. −0.20 at Day 14 and −1.20 vs. −0.23 at Day 28. Sleep Efficiency showed a decline of −0.82 vs. +0.23 at Day 14 and −1.11 vs. +0.30 at Day 28. For Sleep Disturbances, the FBCS group improved by −0.41 vs. −0.05 at Day 14 and −0.55 vs. +0.14 at Day 28. Lastly, Daytime Function scores decreased by −0.73 vs. −0.07 at Day 14 and −0.95 vs. −0.18 at Day 28.Conclusion: The FBCS demonstrated significant effectiveness in improving overall sleep outcomes among patients with primary insomnia. Moreover, the use of DHT enhanced patient adherence and facilitated reliable data collection.Clinical trial registration: https://www.chictr.org.cn/searchprojEN.html, identifier ChiCTR2100051187.

    Design and Performance Evaluation of a Home-Based Automatic Acupoint Identification and Treatment System

    by Zheng Yu, Shengyan Zhang, Linshuai Zhang, Chuanbiao Wen, Shuguang Yu, Jiaqi Sun, Suheng Deng, Hongfu Ci, Yanxiong Gan

    Acupuncture can be effective in relieving pain and reducing drug dependence and abuse caused by chronic pain. However, the cumulative effect of acupuncture requires patients to undergo multiple treatments, which limits its use due to time and economic costs. Currently, existing acupuncture devices include acupoint identification and acupoint stimulation devices. The identification and stimulation functions are separated for these two classes of devices. They were unable to locate the acupoint automatically and required a professional acupuncturist to perform the procedure. Although acupuncture robots that can simultaneously identify the acupoints and initiate treatment are under development, the technology is not yet mature that it is currently not available for general use. To address these issues, we developed an automatic system that combines the identification of acupoints and the administration of treatment. The system is designed to assist users without any knowledge of acupuncture in the management of chronic pain at home. We conducted tests to evaluate the performance of the system in terms of resistance detection accuracy, electroacupuncture accuracy, and acupoint identification test. The results demonstrate that the system significantly improves the accuracy of locating acupoints, indicating its suitability for daily home use as an effective approach to managing chronic pain.

    Revisiting Supersaturation of a Biopharmaceutical Classification System IIB Drug: Evaluation via a Multi-Cup Dissolution Approach and Molecular Dynamic Simulation

    by Yanxiong Gan, Yaxin Xu, Xue Zhang, Huiling Hu, Wenke Xiao, Zheng Yu, Tao Sun, Jinming Zhang, Chuanbiao Wen, Shichao Zheng

    As a subclass of the biopharmaceutical classification system (BCS) class II, basic drugs (BCS IIB) exhibit pH-dependent solubility and tend to generate supersaturation in the gastrointestinal tract, leading to less qualified in vitro–in vivo correlation (IVIVC). This study aims to develop a physiologically based multi-cup dissolution approach to improve the evaluation of the supersaturation for a higher quality of IVIVC and preliminarily explores the molecular mechanism of supersaturation and precipitation of ketoconazole affected by Polyvinylpyrrolidone–vinyl acetate copolymer (PVPVA) and hydroxypropyl methyl-cellulose (HPMC). The concentration of ketoconazole in each cup of the dynamic gastrointestinal model (DGIM) was measured using fiber optical probes. Molecular interactions between ketoconazole and PVPVA or HPMC were simulated by Materials Studio. The results demonstrated that PVPVA and HPMC improved and maintained the supersaturation of ketoconazole. PVPVA exhibited superior precipitation inhibitory effect on ketoconazole molecule aggregation due to slightly stronger van der Waals forces as well as unique electrostatic forces, thereby further enhancing in vitro drug absorption, which correlated well with in vivo drug absorption. Compared with a conventional dissolution apparatus paddle method, the DGIM improved the mean prediction error through the IVIVC from 19.30% to 9.96%, reaching the qualification criteria. In conclusion, the physiologically based multi-cup dissolution approach enables improved evaluation of supersaturation in gastrointestinal transportation of BCS IIB drug ketoconazole, enabling screening screen precipitation inhibitors and achieving qualified IVIVC for drug formulation studies.

    Network module analysis and molecular docking-based study on the mechanism of astragali radix against non-small cell lung cancer

    by Wenke Xiao, Yaxin Xu, Jan P. Baak, Jinrong Dai, Lijia Jing, Hongxia Zhu, Yanxiong Gan, Shichao Zheng

    Background: Most lung cancer patients worldwide (stage IV non-small cell lung cancer, NSCLC) have a poor survival: 25%-30% patients die < 3 months. Yet, of those surviving > 3 months, 10%-15% patients survive (very) long. Astragali radix (AR) is an effective traditional Chinese medicine widely used for non-small cell lung cancer (NSCLC). However, the pharmacological mechanisms of AR on NSCLC remain to be elucidated. Methods: Ultra Performance Liquid Chromatography system coupled with Q-Orbitrap HRMS (UPLC-Q-Orbitrap HRMS) was performed for the qualitative analysis of AR components. Then, network module analysis and molecular docking-based approach was conducted to explore underlying mechanisms of AR on NSCLC. The target genes of AR were obtained from four databases including TCMSP (Traditional Chinese Medicine Systems Pharmacology) database, ETCM (The Encyclopedia of TCM) database, HERB (A high-throughput experiment- and reference-guided database of TCM) database and BATMAN-TCM (a Bioinformatics Analysis Tool for Molecular mechanism of TCM) database. NSCLC related genes were screened by GEO (Gene Expression Omnibus) database. The STRING database was used for protein interaction network construction (PIN) of AR-NSCLC shared target genes. The critical PIN were further constructed based on the topological properties of network nodes. Afterwards the hub genes and network modules were analyzed, and enrichment analysis were employed by the R package clusterProfiler. The Autodock Vina was utilized for molecular docking, and the Gromacs was utilized for molecular dynamics simulations Furthermore, the survival analysis was performed based on TCGA (The Cancer Genome Atlas) database. Results: Seventy-seven AR components absorbed in blood were obtained. The critical network was constructed with 1447 nodes and 28,890 edges. Based on topological analysis, 6 hub target genes and 7 functional modules were gained. were obtained including TP53, SRC, UBC, CTNNB1, EP300, and RELA. After module analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that AR may exert therapeutic effects on NSCLC by regulating JAK-STAT signaling pathway, PI3K-AKT signaling pathway, ErbB signaling pathway, as well as NFkB signaling pathway. After the intersection calculation of the hub targets and the proteins participated in the above pathways, TP53, SRC, EP300, and RELA were obtained. These proteins had good docking affinity with astragaloside IV. Furthermore, RELA was associated with poor prognosis of NSCLC patients. Conclusions: This study could provide chemical component information references for further researches. The potential pharmacological mechanisms of AR on NSCLC were elucidated, promoting the clinical application of AR in treating NSCLC. RELA was selected as a promising candidate biomarker affecting the prognosis of NSCLC patients.

    Supersaturation and Precipitation Applicated in Drug Delivery Systems: Development Strategies and Evaluation Approaches

    by Yanxiong Gan, Jan P. A. Baak, Taijun Chen, Hua Ye, Wan Liao, Huixia Lv, Chuanbiao Wen, Shichao Zheng

    Supersaturation is a promising strategy to improve gastrointestinal absorption of poorly water-soluble drugs. Supersaturation is a metastable state and therefore dissolved drugs often quickly precipitate again. Precipitation inhibitors can prolong the metastable state. Supersaturating drug delivery systems (SDDS) are commonly formulated with precipitation inhibitors, hence the supersaturation is effectively prolonged for absorption, leading to improved bioavailability. This review summarizes the theory of and systemic insight into supersaturation, with the emphasis on biopharmaceutical aspects. Supersaturation research has developed from the generation of supersaturation (pH-shift, prodrug and SDDS) and the inhibition of precipitation (the mechanism of precipitation, the character of precipitation inhibitors and screening precipitation inhibitors). Then, the evaluation approaches to SDDS are discussed, including in vitro, in vivo and in silico studies and in vitro–in vivo correlations. In vitro aspects involve biorelevant medium, biomimetic apparatus and characterization instruments; in vivo aspects involve oral absorption, intestinal perfusion and intestinal content aspiration and in silico aspects involve molecular dynamics simulation and pharmacokinetic simulation. More physiological data of in vitro studies should be taken into account to simulate the in vivo environment. The supersaturation theory should be further completed, especially with regard to physiological conditions.

    Different Data Mining Approaches Based Medical Text Data

    by Wenke Xiao, Lijia Jing, Yaxin Xu, Shichao Zheng, Yanxiong Gan, Chuanbiao Wen

    The amount of medical text data is increasing dramatically. Medical text data record the progress of medicine and imply a large amount of medical knowledge. As a natural language, they are characterized by semistructured, high-dimensional, high data volume semantics and cannot participate in arithmetic operations. Therefore, how to extract useful knowledge or information from the total available data is very important task. Using various techniques of data mining can extract valuable knowledge or information from data. In the current study, we reviewed different approaches to apply for medical text data mining. The advantages and shortcomings for each technique compared to different processes of medical text data were analyzed. We also explored the applications of algorithms for providing insights to the users and enabling them to use the resources for the specific challenges in medical text data. Further, the main challenges in medical text data mining were discussed. Findings of this paper are benefit for helping the researchers to choose the reasonable techniques for mining medical text data and presenting the main challenges to them in medical text data mining.

    Traditional Chinese Medicine Aconiti Radix Cocta Improves Rheumatoid Arthritis via Suppressing COX-1 and COX-2

    by Shuang Li, Rui Li, Ya-Xin Xu, Jan P. A. Baak, Ji-Hai Gao, Jian-Qin Shu, Li-Jia Jing, Xian-Li Meng, Chuan-Biao Wen, Yan-Xiong Gan, et al.

    According to Traditional Chinese Medicine (TCM), Aconiti Radix Cocta (AC) is clinically employed to expel wind, remove dampness, and relieve pain. We evaluated the antirheumatoid arthritis (RA) activities and underlying mechanisms of AC. The chemical constituents of AC were analyzed by high-performance liquid chromatography (HPLC) using three reference compounds (benzoylaconitine, benzoylmesaconine, and benzoylhypacoitine). The anti-RA effects of AC were evaluated in adjuvant-induced arthritis (AIA) rats by hind paw volume and histopathological analysis. The effects of AC on inflammatory cytokines (IL-1β and IL-17A) were determined by enzyme-linked immunosorbent assay. The regulation of cyclooxygenases (COX-1 and/or COX-2) was determined by Western blot and real-time quantitative reverse transcription polymerase chain reaction analyses. AC significantly reduced paw swelling, attenuated the inflammation and bone destruction in joint tissues, and reduced IL-1β and IL-17A in the serum. Moreover, AC downregulated the expression of COX-1 and COX-2 in the synovial tissues. We also identified that AC possesses significant anti-RA activities on AIA, which may be ascribed to the regulation of inflammatory cytokines IL-1β and IL-17, as well as to the inhibition of arachidonic acid signaling pathways. Our findings provide theoretical support for AC as an effective nature-derived therapeutic agent for RA treatment.
