Research and development practice of traditional Chinese medicine based on network target theory and technology / 中国中药杂志

Network targets theory and technology have transcended the limitations of the "single gene, single target" model, aiming to decipher the mechanisms of traditional Chinese medicine(TCM) based on biological network from the perspective of informatics and system. As the core of TCM network pharmacology, with the development of computer science and high-throughput experimental techniques, the network target theory and technology are beginning to exhibit a trend of organic integration with artificial intelligence technology and high-throughput multi-modal multi-omics experimental techniques. Taking the network target analysis of TCM like Yinqiao Qingre Tablets as a typical case, network target theory and technology have achieved the systematic construction, in-depth analysis, and high-throughput multi-modal multi-omics validation of multi-level biological networks spanning from traditional Chinese and Western phenotypes to tissues, cells, molecules, and traditional Chinese and Western medicines. This development helps to address critical issues in the analysis of mechanisms of TCM, including the discovery of key targets, identification of functional components, discovery of synergistic effects among compound ingredients, and elucidation of the regulatory mechanisms of formulae. It provides powerful theoretical and technological support for advancing clinical precision diagnosis and treatment, precise positioning of TCM, and precise research and development of TCM. Thus, a new paradigm of TCM research gradually emerges, combining big data and artificial intelligence(AI) with the integration of human experience and scientific evidence.

Schisandrin B Improves the Hypothermic Preservation of Celsior Solution in Human Umbilical Cord Mesenchymal Stem Cells

BACKGROUND@#Human umbilical cord mesenchymal stem cells (hUCMSCs) have emerged as promising therapy for immune and inflammatory diseases. However, how to maintain the activity and unique properties during cold storage and transportation is one of the key factors affecting the therapeutic efficiency of hUCMSCs. Schisandrin B (SchB) has many functions in cell protection as a natural medicine. In this study, we investigated the protective effects of SchB on the hypothermic preservation of hUCMSCs. @*METHODS@#hUCMSCs were isolated from Wharton’s jelly. Subsequently, hUCMSCs were exposed to cold storage (4 °C) and 24-h re-warming. After that, cells viability, surface markers, immunomodulatory effects, reactive oxygen species (ROS), mitochondrial integrity, apoptosis-related and antioxidant proteins expression level were evaluated. @*RESULTS@#SchB significantly alleviated the cells injury and maintained unique properties such as differentiation potential, level of surface markers and immunomodulatory effects of hUCMSCs. The protective effects of SchB on hUCMSCs after hypothermic storage seemed associated with its inhibition of apoptosis and the anti-oxidative stress effect mediated by nuclear factor erythroid 2–related factor 2 signaling. @*CONCLUSION@#These results demonstrate SchB could be used as an agent for hypothermic preservation of hUCMSCs.

Traditional Chinese medicine network pharmacology: development in new era under guidance of network pharmacology evaluation method guidance / 中国中药杂志

Traditional Chinese medicine(TCM) has unique advantages in the prevention and treatment of diseases owing to its holistic view and more than 2 000 years of experience in the clinical use of natural medicine. The "holistic" characteristic of TCM gives birth to a new generation of research paradigm featuring "network" and "system", which has been developing rapidly in the era of biomedical big data and artificial intelligence. Network pharmacology, a representative research field, provides new ideas and methods for the research of the interdiscipline of artificial intelligence and medicine, the analysis of massive biomedical data, and the transformation from data to knowledge. TCM plays an important role in proposing the core theory of "network target" and promoting the establishment and development of network pharmacology, and has taken the lead in formulating the first international standard of network pharmacology--Network Pharmacology Evaluation Method Guidance. In terms of theory, network target can systematically link drugs and diseases and quantitatively interpret the overall regulatory mechanism of drugs. In the aspect of method, network pharmacology is developing towards a research model that combines computational, experimental, and clinical approaches. This review introduces the resent important progress of TCM network pharmacology in predicting drug targets, understanding the biological basis of drugs and diseases, and searching for disease and syndrome biomarkers. Under the guidance of Network Pharmacology Evaluation Method Guidance, the development of network pharmacology is expected to become more and more standardized and healthy. Network target will help produce more high-quality research outcomes in TCM and effectively boost the modernization and internationalization of TCM.

Objective: To analyze and compare the distribution of the high-risk population of upper gastrointestinal (UGI) cancer and the factors influencing the compliance rate of endoscopic screening in urban China and rural China. Methods: From 2015 to 2017, an epidemiological survey was conducted on residents aged 40-69 in two rural areas (Luoshan county of Henan province, Sheyang county of Jiangsu province) and two urban areas (Changsha city of Hunan province, Harbin city of Heilongjiang province). As a result, high-risk individuals were recommended for endoscopic screening. Chi-square χ(2) test was used to compare the high-risk rate of UGI cancer between urban and rural residents. In addition, the multivariate logistic regression model was used to analyze the factors influencing the compliance rate of endoscopic screening. Results: A total of 48, 310 residents aged 40-69 were enrolled in this study, including 22 870 (47.34%) residents from rural areas and 25 440 (52.66%) residents from urban areas. A total of 23 532 individuals were assessed with a high risk of UGI cancer, with an overall risk rate of 48.71%. A higher proportion of participants with high risk was observed in rural China (56.17%, 12 845/22 870) than in urban China (42.01%, 10 687/25 440). A total of 10 971 high-risk individuals with UGI cancer participated in endoscopic screening, with an overall compliance rate of 46.62% (10 971/23 532), 45.15% (5 799/12 845) in rural China, and 48.40% (5 172/10 687) in urban China. In rural population, the compliance rate of endoscopic screening was higher in those of females, aged 50-69 years, primary school education or above, high income, a family history of UGI cancer, history of gastric and duodenal ulcer, history of reflux esophagitis, and history of superficial gastritis, but lower in smokers (P<0.05). Among the urban population, the compliance rate of endoscopic screening was higher in those aged 40-49 years, uneducated, low income, family history of UGI cancer, history of reflux esophagitis, history of superficial gastritis, but lower in smokers (P<0.05). Conclusions: The proportion of participants with high risk of UGI cancer in rural areas is higher than that of urban areas. The compliance rates of endoscopic screening in urban and rural areas are low, and influencing factors of endoscopic screening exhibit some differences in rural China and urban China.

Da-Cheng-Qi Decoction () Combined with Lactobacillus Acidophilus Improves Gastrointestinal Function of Traumatic Brain-Injured Model Mice / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of Da-Cheng-Qi Decoction (DCQD, ) combined with Lactobacillus acidophilus (LA) on the recovery of gastrointestinal (GI) function in traumatic brain-injured (TBI) mice.@*METHODS@#A total of 150 male C57BL/6 mice were randomly divided into sham-injury, normal saline (NS), DCQD (0.4 mL/day), LA (⩾1 × 10 cfu/day LA), DCQD+LA (LA administration at the same dosage after 4 h of feeding DCQD), and ½ DCQD+LA groups (LA administration at the same dosage after 4 h of feeding ½ DCQD dose) by a random number table, 5-8 mice in each group. The sever TBI model was constructed according to Feeney's enhanced gravitational forces of free falling. On days 1, 3, and 7 post-TBI, plasma diamine oxidase (DAO) and D-lactic acid levels were assessed by enzyme-linked immunosorbent assay (ELISA). Occludin expression in the intestinal epithelium was assessed by Western blot analysis. Transmission electron microscopy (TEM) was used to observe the morphological changes in the network structure of interstitial cells of Cajal (ICC) and change of enteric nervous system-ICC-smooth muscle cell (ENS-ICC-SMC). Immunofluorescence staining was used to detect changes in the network structure of the ICC.@*RESULTS@#Compared with the NS group, occludin expression in the DCQD+LA group significantly increased on Day 1, 3, and 7 post-TBI (P<0.05 or P<0.01). The concentration of DAO significantly decreased in the LA, DCQD, and DCQD+LA groups on Day 3 and 7, whilst the D-lactate concentrations in the LA and ½ DCQD+LA groups decreased on Day 1 and 3 post-injury (P<0.05 or P<0.01). The NS group experienced a great damage on the ENS-ICC-SMC network morphology and ICC network structure, and all treatment groups had some improvements, among which the DCQD+LA group presented relatively intact network morphology.@*CONCLUSIONS@#DCQD combined with LA treatment could effectively repair the intestinal mucosal barrier and improve GI motility in mice after TBI. The combination of DCQD and LA was more effective than their respective monotherapies.

Enhanced recovery after surgery protocols in functional endoscopic sinus surgery for patients with chronic rhinosinusitis with nasal polyps: a randomized clinical trial / 中华医学杂志(英文版)

BACKGROUND@#Enhanced recovery after surgery (ERAS) protocols are a series of perioperative care to optimize preoperative preparation, prevent postoperative complications, minimize stress, and speed up recovery. This study aimed to assess the impact of ERAS protocols for functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).@*METHODS@#One hundred and two patients with CRSwNP undergoing FESS were randomly divided into the ERAS group and the control group. The outcomes of the Self-Rating Anxiety Scale (SAS), Visual Analogue Scale (VAS), Medical Outcomes Study Sleep Scale (MOS-SS) and Kolcaba Comfort Scale Questionnaire (GCQ) were determined in both groups. The serum levels of C-reactive protein (CRP) were compared preoperatively and 24 hours postoperatively.@*RESULTS@#The ERAS group had a significantly better SAS scores than did the control group (28 [24, 35] vs. 43 [42, 47], Z = 5.968, P  0.05); However, the CRP level in 24 hours postoperatively was significantly lower in the ERAS group than that in the control group (2.5 [1.4, 3.9] vs. 6.6 [3.8, 9.0], Z = 5.027, P  0.05), hemorrhage, aspiration and tumble, were not increased in the ERAS group compared with those in the control group. The ERAS group had a significantly shorter length of hospital stay (5 [4, 5] days vs. 8 [8,9] days, Z = 8.939, P < 0.001) and hospitalization expenses ($ 2670 [2375, 2740] vs. $3129 [3116, 3456], Z = 8.514, P < 0.001).@*CONCLUSIONS@#ERAS protocols might optimize FESS for patients with CRSwNP by reducing psychological and physical stress, shortening the length of hospital stay and lowering hospitalization expenses without increasing postoperative complications.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry, No. ChiCTR1800015791; http://www.chictr.org.cn/showproj.aspx?proj=26872.

Tongue coating microbiome as a potential biomarker for gastritis including precancerous cascade

The development of gastritis is associated with an increased risk of gastric cancer. Current invasive gastritis diagnostic methods are not suitable for monitoring progress. In this work based on 78 gastritis patients and 50 healthy individuals, we observed that the variation of tongue-coating microbiota was associated with the occurrence and development of gastritis. Twenty-one microbial species were identified for differentiating tongue-coating microbiomes of gastritis and healthy individuals. Pathways such as microbial metabolism in diverse environments, biosynthesis of antibiotics and bacterial chemotaxis were up-regulated in gastritis patients. The abundance of Campylobacter concisus was found associated with the gastric precancerous cascade. Furthermore, Campylobacter concisus could be detected in tongue coating and gastric fluid in a validation cohort containing 38 gastritis patients. These observations provided biological evidence of tongue diagnosis in traditional Chinese medicine, and indicated that tongue-coating microbiome could be a potential non-invasive biomarker, which might be suitable for long-term monitoring of gastritis.

Whole Genome Analysis Reveals New Insights into Macrolide Resistance in Mycoplasma pneumoniae / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>Mutations in 23S rRNA gene are known to be associated with macrolide resistance in Mycoplasma pneumoniae (M. pneumoniae). However, these mutations alone do not fully explain the high resistance rates in Asia. The aim of this study was to investigate other possible mutations involved in macrolide resistance in M. pneumoniae.</p><p><b>METHODS</b>The whole genomes of 10 clinical isolates of M. pneumoniae with macrolide resistance were sequenced by Illumina HiSeq2000 platform. The role of the macrolide-specific efflux transporter was assessed by efflux-pump inhibition assays with reserpine and carbonyl cyanide m-chlorophenyl-hydrazone (CCCP).</p><p><b>RESULTS</b>A total of 56 single nucleotide polymorphisms (SNPs) were identified in 10 clinical isolates in comparison to the reference strains M129 and FH. Strikingly, 4 of 30 SNPs causing non-synonymous mutations were clustered in macrolide-specific efflux system gene macB encoding macrolide-specific efflux pump protein of the ATP-binding cassette transporter family. In assays of the minimal inhibitory concentrations (MIC) of macrolide antibiotics in the presence of the efflux pump inhibitors caused a significant decrease of MICs, even under detectable levels in some strains.</p><p><b>CONCLUSION</b>Our study suggests that macrolide efflux pump may contribute to macrolide resistance in M. pneumoniae in addition to the common point mutations in 23S rRNA gene.</p>
