RESUMO

Based on summarizing the essential procedures and elements of traditional manipulation techniques of warming needle moxibustion and determining the quantitative parameters and indicators for evaluating the operation of this acupuncture technique, a training instrument of warming needle moxibustion was developed and adopted in the curriculum teaching of practice. It showed that this instrument could quantify the speed of fixing mugwort ball on the needle handle, the number of the prepared mugwort ball, the duration for anti-vibration, the frequency of anti-vibration and the burning time of mugwort ball. The instrument could objectively evaluate the skills of warming needle moxibustion and the effects of fixing mugwort ball. Besides, it may provide the references to improve the protocol of the future research. The development and application of the practical training instrument of warming needle moxibustion is conductive to cultivate the standardization and accuracy of the technique operation in students, and it is significant for objectif-ying the teaching course of warming needle and teaching assessment, as well as for diversifying the teaching modes. Moreover, it plays an exemplary role in the practical training of other acupuncture and moxibustion techniques.

RESUMO

OBJECTIVES: Ulcerative colitis (UC) is a common inflammatory bowel disorder. Gentiana scabra Bunge is a traditional medicinal plant that is used to treat a variety of diseases. Studies have shown that gentianine (GTN) from Gentiana scabra inhibits the development of inflammatory diseases. The purpose of this study was to investigate the effect and possible mechanism of action of GTN on UC in mice. METHODS: An animal model of UC was established using dextran sulfate sodium (DSS). Mice were administered intraperitoneally with GTN (12.5, 25, or 50 mg/kg/day) for seven days. Body weight and disease activity index (DAI) were monitored daily during GTN administration. Colon length, pathological changes, and myeloperoxidase (MPO) activity were measured following GTN administration. The signalling pathways regulated by GTN were analysed using machine learning. HT-29 cells were used to verify the effect and mechanism of action of GTN on UC in vitro. RESULTS: GTN suppressed weight loss, shortened colon length, alleviated colon injury, and reduced the DAI score and MPO activity of mice with UC in a dose-dependent manner. Further analysis showed that GTN inhibited the NOD-like receptor (NLR) signalling pathway. GTN markedly decreased the levels of NLR signalling pathway-related proteins. Moreover, GTN decreased the levels of pyroptosis-related proteins, IL-1ß and IL-18. The in vitro data were consistent with those of animal experiments. Furthermore, TLR4 and NLRP3 overexpression eliminated the protective effects of GTN in HT-29 cells. CONCLUSION: Gentianine alleviated DSS-induced UC by inhibiting TLR4/NLRP3-mediated pyroptosis.

RESUMO

People living with human immunodeficiency virus (PLWH) have persistent malnutrition, intestinal barrier dysfunction, and gut microbial imbalance. The interplay between gut microbiota and nutrients is involved in the immune reconstitution of PLWH. To evaluate the effects of whole-protein enteral nutrition formula supplementation on T-cell levels, intestinal barrier function, nutritional status, and gut microbiota composition in human immunodeficiency virus (HIV)-infected immunological nonresponders (INRs) who failed to normalize CD4+ T-cell counts, with a number <350 cells/µL, a pilot study was carried out in 13 HIV-infected INRs undergoing antiretroviral therapy who received a 3-month phase supplementation of 200 mL/200 kcal/45 g whole-protein enteral nutrition formula once daily. Our primary endpoint was increased CD4+ T-cell counts. Secondary outcome parameters were changes in intestinal barrier function, nutritional status, and gut microbiota composition. We showed that CD4+ T-cell counts of HIV-infected INRs increased significantly after the 3-month supplementation. Dietary supplementation for 3 months improved the intestinal barrier function and nutritional status of HIV-infected INRs. Furthermore, the enteral nutrition formula significantly decreased the relative abundance of Escherichia at the genus level and increased the alpha diversity of gut microbiota in HIV-infected INRs. The findings demonstrated that the whole-protein enteral nutrition formula aids in reducing Escherichia and improving intestinal barrier function in HIV-infected INRs. This study provides insight into the role of nutrients in the improvement of immune reconstitution in HIV-infected INRs. This study is registered in the Chinese Clinical Trial Registry (Document No. ChiCTR2000037839; http://www.chictr.org.cn/index.aspx).

RESUMO

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.

RESUMO

OBJECTIVES: To observe the changes of skin blood flow perfusion at Waiguan (TE 5) caused by mild moxibustion with moxa stick and infrared mild moxibustion using laser speckle contrast imaging technology, and to compare the microcirculatory effect during and after both moxibustion methods and explore the dose-response relationship of moxibustion. METHODS: Twenty-four healthy participants were treated with mild moxibustion with moxa stick and infrared mild moxibustion at left Waiguan (TE 5). The record started when the skin temperature reached (44±1) °C, and both moxibustion methods were provided within this temperature range. The 20-minute moxibustion process was divided into four stages (5, 10, 15, and 20 min) using interpolation method, and each participant completed eight interventions with a minimum 24-hour interval between different interventions. The skin surface temperature of the left Waiguan (TE 5) was monitored when both moxibustion interventions were given for 10 min using a TES1306 thermocouple thermometer. The skin microcirculatory blood perfusion units (MBPU) of left Waiguan (TE 5) was measured using a PSIN-01087 laser speckle blood flow imager 1 min before moxibustion, at 5, 10, 15, 20 min during moxibustion and continuously for 20 min after moxibustion in each intervention. RESULTS: The skin surface temperature of the left Waiguan (TE 5) remained within the range of (44±1) °C during both moxibustion methods, with no statistically significant difference (P>0.05). Compared with that before moxibustion, the MBPU of the left Waiguan (TE 5) was increased significantly at 5, 10, 15, and 20 min of both moxibustion methods (P<0.05, P<0.01). Compared with moxibustion for 10, 15 and 20 min, the MBPU of the left Waiguan (TE 5) of moxibustion for 5 min was lower in both moxibustion methods (P<0.01). For both moxibustion methods with the same moxibustion course, the MBPU of the left Waiguan (TE 5) 20 min after intervention was significantly higher than that at 1 min before moxibustion (P<0.001), and there was no significant difference in MBPU between 1 min before moxibustion and 20 min after moxibustion among different groups (P>0.05). Within the same moxibustion method, the MBPU of the left Waiguan (TE 5) 20 min after moxibustion with the intervention of 5 min was lower compared to that of 10, 15, and 20 min of moxibustion (P<0.001), with no significant differences between 10, 15, and 20 min of moxibustion (P>0.05). CONCLUSIONS: When controlling the skin temperature at Waiguan (TE 5) within (44±1) °C, infrared mild moxibustion has similar effects on skin microcirculatory blood perfusion as traditional mild moxibustion with moxa sticks. From a dose-response perspective, microcirculation reached a stable state after 10 min of moxibustion, and moxibustion interventions lasting for more than 10 min shows better therapeutic effects.

RESUMO

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the main cause of chronic liver disease. Baicalin (Bai), a bioactive molecule found in Scutellaria baicalensis Georgi, possesses antioxidant and antiinflammatory properties. These activities suggest Bai could be a promising therapeutic agent against NAFLD; however, its specific effects and underlying mechanism are still not clear. This study aims to explore the effect of Bai to attenuate MAFLD and associated molecular mechanisms. Bai (50, 100 or 200 mg/kg) was orally administered to db/db mice with MAFLD for 4 weeks or db/m mice as the normal control. Bai markedly attenuated lipid accumulation, cirrhosis and hepatocytes apoptosis in the liver tissues of MAFLD mice, suggesting strong ability to attenuate MAFLD. Bai significantly reduced proinflammatory biomarkers and enhanced antioxidant enzymes, which appeared to be modulated by the upregulated p62-Keap1-Nrf2 signalling cascade; furthermore, cotreatment of Bai and all-trans-retinoic acid (Nrf2 inhibitor) demonstrated markedly weakened liver protective effects by Bai and its induced antioxidant and antiinflammatory responses. The present study supported the use of Bai in attenuating MAFLD as a promising therapeutic agent, and its strong mechanism of action in association with the upregulating the p62-keap1-Nrf2 pathway.

RESUMO

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

RESUMO

OBJECTIVE: To observe the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on plasma melatonin (MLT) content and insulin receptor expression in the liver, the skeletal muscles, and the pancreas of Zucker diabetic fatty (ZDF) rats, so as to explore the hypoglycemic mechanism of taVNS. METHODS: Thirty male ZDF rats were randomly divided into model group, taVNS group and sham-taVNS group, with 10 rats in each group; besides, 10 male Zucker lean rats of the same strain were collected for the blank control group. ZDF rats were fed with high-fat diet to induce type 2 diabetes mellitus (T2DM) rat model. In the taVNS group, HANS-100A electroacupuncture instrument was used to stimulate the cavum conchae of both sides. The stimulation sites of rats in the sham-taVNS were the same as the taVNS group, but without electricity delivered. The above interventions were performed 30 min each time, once daily, lasting for 6 weeks. Fasting blood glucose (FBG) was measured weekly in each group, the plasma metatonin (MLT) content was detected by ELISA, and the insulin receptor expression level in the liver, the skeletal muscle and the pancreas was determined by Western blot. RESULTS: Compared with the blank control group, the level of FBG of rats were increased (P<0.01), the plasma MLT content was decreased (P<0.01) and the insulin receptor expression level in the pancreatic tissue was decreased (P<0.01) in the model group. In the taVNS gruop, FBG was decreased (P<0.05, P<0.01), the plasma MLT content was increased (P<0.01), and the insulin receptor expression level in the liver, the skeletal muscle and the pancreas was increased (P<0.05, P<0.01, P<0.001) when compared with the model group. Compared with the taVNS group, FBG was increased (P<0.05, P<0.01), the plasma MLT content was decreased (P<0.01), and the expression level of insulin receptors in the skeletal muscle and the pancreas was decreased (P<0.01, P<0.001) in the sham-taVNS group. CONCLUSION: The taVNS can improve the insulin resistance and ultimately obtain the antihyperglycemic effect through regulating MLT concentration.

RESUMO

OBJECTIVE: The purpose of this study is to reveal the mechanism of action of Yi Qi Tong Qiao Pill (YQTQP) in the treatment of allergic rhinitis (AR), as well as establish a paradigm for the researches on traditional Chinese medicine (TCM) from systematic perspective. METHODS: Based on the data collected from TCM-related and disease-related databases, target profiles of compounds in YQTQP were calculated through network-based algorithms and holistic targets of TQTQP was constructed. Network target analysis was performed to explore the potential mechanisms of YQTQP in the treatment of AR and the mechanisms were classified into different modules according to their biological functions. Besides, animal and clinical experiments were conducted to validate our findings inferred from Network target analysis. RESULTS: Network target analysis showed that YQTQP targeted 12 main pathways or biological processes related to AR, represented by those related to IL-4, IFN-γ, TNF-α and IL-13. These results could be classified into 3 biological modules, including regulation of immune and inflammation, epithelial barrier disorder and cell adhesion. Finally, a series of experiments composed of animal and clinical experiments, proved our findings and confirmed that YQTQP could improve related symptoms of AR, like permeability of nasal mucosa epithelium. CONCLUSION: A combination of Network target analysis and the experimental validation indicated that YQTQP was effective in the treatment of AR and might provide a new insight on revealing the mechanism of TCM against diseases.

RESUMO

OBJECTIVE: To determine whether acupotomy ameliorates immobilization-induced muscle contracture and fibrosis via Wnt/ß-catenin signaling pathway. METHODS: Thirty Wistar rats were randomly divided into 5 groups (n=6) by a random number table, including control, immobilization, passive stretching, acupotomy, and acupotomy 3 weeks (3-w) groups. The rat model of gastrocnemius contracture was established by immobilizing the right hind limb in plantar flexion for 4 weeks. Rats in the passive stretching group received passive stretching at gastrocnemius, a daily series of 10 repetitions for 30 s each at 30-s intervals for 10 consecutive days. Rats in the acupotomy and acupotomy 3-w groups received acupotomy once and combined with passive stretching at gastrocnemius a daily series of 10 repetitions for 30 s each at 30-s intervals for 10 consecutive days. Additionally, rats in the acupotomy 3-w group were allowed to walk freely for 3 weeks after 10-day therapy. After treatment, range of motion (ROM), gait analysis [i.e., paw area, stance/swing and maximum ratio of paw area to paw area duration (Max dA/dT)], gastrocnemius wet weight and the ratio of muscle wet weight to body weight (MWW/BW) were tested. Gastrocnemius morphometric and muscle fiber cross-sectional area (CSA) were assessed by hematoxylin-eosin staining. Fibrosis-related mRNA expressions (i.e., Wnt 1, ß-catenin, axin-2, α-smooth muscle actin, fibronectin, and types I and III collagen) were measured using real-time quantitative polymerase chain reactions. Wnt 1, ß-catenin and fibronectin concentrations were measured by enzyme-linked immunosorbent assay. Types I and III collagen in the perimysium and endomysium were analyzed using immunofluorescence. RESULTS: Compared with the control group, ROM, gait function, muscle weight, MWW/BW and CSA were significantly decreased in the immobilization group (all P<0.01), while protein levels of types I and III collagen, Wnt 1, ß-catenin, fibronectin and mRNA levels of fibrosis-related genes were obviously increased (all P<0.01). Treatment with passive stretching or acupotomy restored ROM and gait function and increased muscle wet weight, MWW/BW and CSA (all P<0.05), while protein expression levels of Wnt 1, ß-catenin, fibronectin, types I and III collagen and mRNA levels of fibrosis-related genes were remarkably declined compared with the immobilization group (all P<0.05). Compared with passive stretching group, ROM, gait function, MWW was remarkably restored (all P<0.05), and mRNA levels of fibrosis-related genes as well as protein expression levels of Wnt 1, ß-catenin, fibronectin, types I and III collagen in the acupotomy group were obviously decreased (all P<0.05). Compared with the acupotomy group, ROM, paw area, Max dA/dT, and MWW were restored (all P<0.05), and mRNA levels of fibrosis-related genes along with protein levels of Wnt 1, ß-catenin, fibronectin, types I and III collagen in the acupotomy 3-w group were decreased (P<0.05). CONCLUSION: Improvements in motor function, muscle contractures, and muscle fibrosis induced by acupotomy correlates with the inhibition of Wnt/ß-catenin signaling pathway.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic is an ongoing global health concern, and effective antiviral reagents are urgently needed. Traditional Chinese medicine theory-driven natural drug research and development (TCMT-NDRD) is a feasible method to address this issue as the traditional Chinese medicine formulae have been shown effective in the treatment of COVID-19. Huashi Baidu decoction (Q-14) is a clinically approved formula for COVID-19 therapy with antiviral and anti-inflammatory effects. Here, an integrative pharmacological strategy was applied to identify the antiviral and anti-inflammatory bioactive compounds from Q-14. Overall, a total of 343 chemical compounds were initially characterized, and 60 prototype compounds in Q-14 were subsequently traced in plasma using ultrahigh-performance liquid chromatography with quadrupole time-of-flight mass spectrometry. Among the 60 compounds, six compounds (magnolol, glycyrrhisoflavone, licoisoflavone A, emodin, echinatin, and quercetin) were identified showing a dose-dependent inhibition effect on the SARS-CoV-2 infection, including two inhibitors (echinatin and quercetin) of the main protease (Mpro), as well as two inhibitors (glycyrrhisoflavone and licoisoflavone A) of the RNA-dependent RNA polymerase (RdRp). Meanwhile, three anti-inflammatory components, including licochalcone B, echinatin, and glycyrrhisoflavone, were identified in a SARS-CoV-2-infected inflammatory cell model. In addition, glycyrrhisoflavone and licoisoflavone A also displayed strong inhibitory activities against cAMP-specific 3',5'-cyclic phosphodiesterase 4 (PDE4). Crystal structures of PDE4 in complex with glycyrrhisoflavone or licoisoflavone A were determined at resolutions of 1.54 Å and 1.65 Å, respectively, and both compounds bind in the active site of PDE4 with similar interactions. These findings will greatly stimulate the study of TCMT-NDRD against COVID-19.

RESUMO

INTRODUCTION: Seed-based analysis has shown that transcutaneous auricular vagus nerve stimulation (taVNS) can modulate the dysfunctional brain network in patients with major depressive disorder (MDD). However, the voxel-based neuropsychological mechanism of taVNS on patients with first-episode MDD is poorly understood. The objective of this study was to assess the effects of an 8-week course of taVNS on patients with first-episode MDD. METHODS: Twenty-two patients with first-episode MDD accepted an 8-week course of taVNS treatment. Resting-state functional magnetic resonance imaging (rs-fMRI) scans were performed before and after treatment. Voxel-based analyses were performed to characterize spontaneous brain activity. Healthy controls (n=23) were recruited to minimize test-retest effects. Analysis of covariance (ANCOVA) was performed to ascertain treatment-related changes. Then, correlations between changes in brain activity and the Hamilton Depression Rating Scale (HAM-D)/Hamilton Anxiety Scale (HAM-A) remission rate were estimated. RESULTS: Significant group-by-time interactions on voxel-based analyses were observed in the inferior ventral striatum (VSi) and precuneus. Post-hoc analyses showed that taVNS inhibited higher brain activity in the VSi, while upregulating it in the precuneus. Functional connectivity (FC) between the VSi and precuneus decreased. Positive correlations were found between the HAM-D remission rate and changes in brain activity in the VSi. CONCLUSION: taVNS reduced the FC between VSi and precuneus by normalizing the abnormal spontaneous brain activity of VSi in first-episode MDD patients.

RESUMO

To make up for the shortcomings of traditional mild moxibustion, according to the principle and technical operation characteristics of traditional mild moxibustion, combined with temperature control technology, a novel infrared mild moxibustion device is developed, which is capable of real-time accurate temperature control. This novel infrares mild moxibustion device is composed of a host computer and an infrared radiation head. The host computer includes four modules: power supply, human-computer interaction interface, micro control unit (MCU) and drive circuit. The infrared radiation head mainly includes an infrared heater and a temperature sensor. This novel infrared mild moxibustion device is easy to operate. The electrothermal heating tablet can generate infrared radiation of 3 000-13 000 nm. After the temperature of the infrared heater is stabilized, the range of temperature change is ±0.50 ℃, realizing the goal of precise temperature control. In addition, it can operate moxibustion treatment at multiple acupoints at the same time, which is conducive to the dose-effect evaluation of mild moxibustion.

RESUMO

PURPOSE: To report the efficacy and safety of postoperative adjuvant hepatic arterial infusion chemotherapy (HAIC) with 5-fluorouracil and oxaliplatin (FOLFOX) in hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI). PATIENTS AND METHODS: In this randomized, open-label, multicenter trial, histologically confirmed HCC patients with MVI were randomly assigned (1:1) to receive adjuvant FOLFOX-HAIC (treatment group) or routine follow-up (control group). The primary end point was disease-free survival (DFS) by intention-to-treat (ITT) analysis while secondary end points were overall survival, recurrence rate, and safety. RESULTS: Between June 2016 and August 2021, a total of 315 patients (ITT population) at five centers were randomly assigned to the treatment group (n = 157) or the control group (n = 158). In the ITT population, the median DFS was 20.3 months (95% CI, 10.4 to 30.3) in the treatment group versus 10.0 months (95% CI, 6.8 to 13.2) in the control group (hazard ratio, 0.59; 95% CI, 0.43 to 0.81; P = .001). The overall survival rates at 1 year, 2 years, and 3 years were 93.8% (95% CI, 89.8 to 98.1), 86.4% (95% CI, 80.0 to 93.2), and 80.4% (95% CI, 71.9 to 89.9) for the treatment group and 92.0% (95% CI, 87.6 to 96.7), 86.0% (95% CI, 79.9 to 92.6), and 74.9% (95% CI, 65.5 to 85.7) for the control group (hazard ratio, 0.64; 95% CI, 0.36 to 1.14; P = .130), respectively. The recurrence rates were 40.1% (63/157) in the treatment group and 55.7% (88/158) in the control group. Majority of the adverse events were grade 0-1 (83.8%), with no treatment-related death in both groups. CONCLUSION: Postoperative adjuvant HAIC with FOLFOX significantly improved the DFS benefits with acceptable toxicities in HCC patients with MVI.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Weifuchun capsule (WFC) is a traditional Chinese patent medicine for chronic atrophic gastritis (CAG) in clinic. However, the mechanism of action of WFC for CAG still remains unclear due to its complex composition. AIM OF THE STUDY: The study was projected to uncover the mechanism of action of WFC and the corresponding pharmacodynamic substance of WFC against CAG as well as providing a standard example for the research of traditional Chinese medicine (TCM) from the perspective of the network and the system. MATERIALS AND METHODS: We identified the compounds of WFC through LC-MS/MS analysis and performed a systematic network targets analysis for WFC in the treatment of CAG which thoroughly described the mechanism of action of WFC for CAG. Based on analysis integrating omics data and algorithms, we focused on the specific immune regulatory role of WFC in the treatment of CAG, especially on a hub pathway, Toll-like receptor signaling pathway and thus deciphered the role of WFC in immune regulation, anti-inflammation and mediation of HES6. In experiments part, MNNG-GES-1-cell line and rat models were used to validate our findings. RESULTS: In this study, compounds of WFC are identified through LC‒MS/MS and network target analysis is performed to dissect the specific immunoregulatory effect as well as mediation of HES6, a newly discovered biomolecule related to gastritis carcinoma progression, of WFC on CAG through the Toll-like receptor signaling pathway. Based on cell line and rat models, we verify the mechanism of action of WFC for CAG in inhibiting inflammatory cytokines, regulating immune cells like T cells and macrophages, related genes including TLR2 and CD14. It is also validated that WFC inhibits the expression of HES6 (P < 0.05). CONCLUSION: Based on the combination of computational strategy and experiments, our study offers a comprehensive analysis to reveal the role of WFC in regulating immune response, inhibiting inflammation in the treatment of CAG, and provides a standard example for the research of TCM from the perspective of the network and the system.

RESUMO

Objective: Preterm birth is one of the most important health problems in the world. Feeding intolerance is one of the most common and serious complications of premature infant. The purpose of this study was to explore the effect of Chinese pediatric Tuina on the prevention of feeding intolerance in favour of weight gain in premature infants. Methods: A prospective randomized controlled study was conducted in the Department of Neonatology in our hospital. Premature infants were recruited and randomly assigned to an intervention group or a control group. Premature infants in the intervention group received a Chinese pediatric Tuina intervention by professional chiropractors, while premature infants in the control group received standard care. The incidence of feeding intolerance and weight gain situation were compared between the two groups. Result: After 1 week of intervention, the body weight (2.5±0.5 vs 2.0±0.4, p=0.038), head circumference (32.8±1.7 vs 29.9±1.4, p=0.041), albumin (34.6±5.8 vs 28.4±6.1, p-0.026) and prealbumin (155.8±35.2 vs 113.6±36.8, p=0.021) of preterm infants in the intervention group were significantly better than those in the control group. The incidence of feeding intolerance (7 vs 15, p=0.032) in the intervention group was significantly lower than that in the control group. Although there were no statistically significant differences (P>0.05), the incidences of gastrointestinal bleeding, necrotizing enterocolitis, and liver insufficiency were lower in the intervention group than in the control group. Conclusion: Chinese pediatric Tuina can effectively prevent the occurrence of feeding intolerance in premature infants and be conducive to the weight gain and improving nutritional status of premature infants.

RESUMO

Network pharmacology (NP) provides a new methodological perspective for understanding traditional medicine from a holistic perspective, giving rise to frontiers such as traditional Chinese medicine network pharmacology (TCM-NP). With the development of artificial intelligence (AI) technology, it is key for NP to develop network-based AI methods to reveal the treatment mechanism of complex diseases from massive omics data. In this review, focusing on the TCM-NP, we summarize involved AI methods into three categories: network relationship mining, network target positioning and network target navigating, and present the typical application of TCM-NP in uncovering biological basis and clinical value of Cold/Hot syndromes. Collectively, our review provides researchers with an innovative overview of the methodological progress of NP and its application in TCM from the AI perspective.
