Discovery of psoralen as a quorum sensing inhibitor suppresses Pseudomonas aeruginosa virulence.

Pseudomonas aeruginosa is a common opportunistic pathogen with growing resistance and presents heightened treatment challenges. Quorum sensing (QS) is a cell-to-cell communication system that contributes to the production of a variety of virulence factors and is also related to biofilm formation of P. aeruginosa. Compared to traditional antibiotics which kill bacteria directly, the anti-virulence strategy by targeting QS is a promising strategy for combating pseudomonal infections. In this study, the QS inhibition potential of the compounds derived from the Traditional Chinese Medicines was evaluated by using in silico, in vitro, and in vivo analyses. The results showed that psoralen, a natural furocoumarin compound derived from Psoralea corylifolia L., was capable of simultaneously inhibiting the three main QS regulators, LasR, RhlR, and PqsR of P. aeruginosa. Psoralen had no bactericidal activity but could widely inhibit the production of extracellular proteases, pyocyanin, and biofilm, and the cell motilities of the model and clinical P. aeruginosa strains. RNA-sequencing and quantitative PCR analyses further demonstrated that a majority of QS-activated genes in P. aeruginosa were suppressed by psoralen. The supplementation of psoralen could protect Caenorhabditis elegans from P. aeruginosa challenge, especially for the hypervirulent strain PA14. Moreover, psoralen showed synergistic antibacterial effects with polymyxin B, levofloxacin, and kanamycin. In conclusions, this study identifies the anti-QS and antibiofilm effects of psoralen against P. aeruginosa strains and sheds light on the discovery of anti-pseudomonal drugs among Traditional Chinese Medicines. KEY POINTS: • Psoralen derived from Psoralea corylifolia L. inhibits the virulence-related phenotypes of P. aeruginosa. • Psoralen simultaneously targets the three core regulators of P. aeruginosa QS system and inhibits the expression of a large part of downstream genes. • Psoralen protects C. elegans from P. aeruginosa challenge and enhances the susceptibility of P. aeruginosa to antibiotics.

The formation mechanism and textural properties of a complex gel based on soybean glycinin-chitosan complex coacervates: Effects of pH, heat treatment temperature and centrifugation.

The soybean glycinin (11S)-chitosan (CS) complex gels with various textural properties were successfully constructed. The process involved the initial formation of 11S-CS coacervates through electrostatic interactions, followed by a heating treatment to obtain the final complex gels. The impacts of pH, heating temperature, and centrifugation on 11S-CS complex gel properties were investigated. The results indicated that the pore arrangement of the gel formed at pH 7.3 was more tightly and uniformly packed than those formed at pH 6.8 and 7.8. Centrifugation facilitated denser and more ordered gel structures at the three pH values, while increasing the heating temperature exhibited the opposite trend at pH 6.8 and 7.8. These structural differences were also reflected in the rheological and textural properties of the gel. The 11S-CS complex gels exhibited an elasticity-based gel property. The textural properties of gels formed at pH 6.8 were stronger compared to those formed at pH 7.3 and 7.8. However, when the 11S-CS coacervates were heated without centrifugation, the resulting gels were weak. This study emphasizes the potential of using protein/polysaccharide associative interactions during gel formation to alter the microstructure of the gel, meeting various production requirements.

Metabolomics analysis of flavor differences in Shuixian (Camellia sinensis) tea from different production regions and their microbial associations.

Shuixian is renowned for its "rock flavor". However, the variations in Shuixian flavor are unclear, as the discussion mainly considers regional factors and overlooks the role of microorganisms. Sensory evaluation of Shuixian from three different regions (Zhengyan, Banyan, and Waishan) revealed that each had unique flavor characteristics: a woody aroma with slight acidity, a strong floral and fruity aroma with good freshness, and a distinct sweet aroma and sourness. Metabolomic analyses have revealed that 2-methylpyrazine was a crucial component of the woody aroma, whereas other metabolites contributed to sweet aroma, freshness, and acidity. Moreover, examinations of the relationship between flavor metabolites and microorganisms revealed that fungi had a more pronounced influence on the metabolite content of Shuixian. The study evaluated the role of fermentation microorganisms in shaping the flavor based on Shuixian flavor analyses, contributing to further research into the "rock flavor", as well as potential microbial interventions.

Massage therapy can effectively relieve cancer pain: A meta-analysis.

BACKGROUND: To critically evaluate the effects of massage therapy on cancer pain. METHODS: Nine Chinese and English databases (PubMed, Cochrane Library, Embase, SCOPUS, Web of Science core, China Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang, and VIP) were systematically searched from the inception of databases to November 2022 for randomized controlled trials. According to Cochrane Collaboration, 2 reviewers independently assessed the risk of bias and extracted data from the included studies. All analyses were performed with Review Manager 5.4. RESULTS: Thirteen randomized controlled trials were included in the meta-analysis, containing 1000 patients (498 in the massage therapy group and 502 in the control group). Massage therapy could significantly relieve cancer pain in patients (standardized mean difference = -1.16, 95% confidence interval [-1.39, -0.93], P < .00001), especially those in the perioperative period and those with hematological malignancies. Foot reflexology and hand acupressure had a moderate effect on cancer pain relief, with hand acupressure being more effective. Massage duration of 10 to 30 minutes and a program length of ≥1 week had a better effect and could significantly relieve pain. The occurrence of adverse events was reported in 4 of the 13 studies, all of which were no adverse events. CONCLUSIONS: Massage therapy can be used as a complementary alternative therapy to relieve cancer pain in patients with hematological malignancies, breast cancer, and cancers of the digestive system. It is suggested that chemotherapy patients use foot reflexology, and perioperative period patients use hand acupressure. A massage duration of 10 to 30 minutes and a program length of ≥1 week is recommended to achieve better effects.

Which Exercise Approaches Work for Relieving Cancer-Related Fatigue? A Network Meta-analysis.

OBJECTIVE: To determine the most effective exercise modalities for managing cancer-related fatigue during and after cancer treatment. DESIGN: Network meta-analysis (NMA) of randomized controlled trials. LITERATURE SEARCH: Seven electronic databases were systematically searched from inception to January 2022. STUDY SELECTION CRITERIA: Randomized controlled trials testing the effects of exercise on relieving cancer-related fatigue in adult patients with cancer. DATA SYNTHESIS: An NMA of 56 studies was conducted, and the PRISMA-NMA guidelines were followed when reporting results. To determine the most effective interventions, the surface under the cumulative ranking curve (SUCRA) value was calculated for each exercise modality. RESULTS: Combined aerobic and resistance exercise (standardized mean difference [SMD], 1.57; credible interval [CrI], 1.03-2.10), yoga (SMD, 1.02; CrI: 0.44, 1.60), and regular physical activity (SMD, 1.07; CrI: 0.21, 1.92) could significantly alleviate cancer-related fatigue compared to control groups (usual care, wait-list, and regular physical activity). Combined aerobic and resistance exercise (SUCRA, 97.2%) had the highest probability of efficacy, followed by yoga (SUCRA, 75.5%) and regular physical activity (SUCRA, 74.1%). During cancer treatment, combined aerobic and resistance exercise (SUCRA, 94.5%) ranked first in efficacy, followed by regular physical activity (SUCRA, 82.1%) and yoga (SUCRA, 73.8%). After cancer treatment, only combined aerobic and resistance exercise (SMD, 0.99; CrI: 0.13, 1.84) had a significant effect on cancer-related fatigue. CONCLUSION: Combined aerobic and resistance exercise, yoga, and regular physical activity were the most effective exercise modalities for alleviating cancer-related fatigue. Combined aerobic and resistance exercise is recommended during and after cancer treatment. J Orthop Sports Phys Ther 2023;53(6):1-10. Epub: 23 March 2023. doi:10.2519/jospt.2023.11251.

A novel zein-selenium complex nanoparticle with controllable size: Quantitative design, physical properties and cytotoxicity in vitro.

In this study, after proposing a method for the preparation of selenium nanoparticles (Se NPs) with stable properties using zein, the physico-chemical properties of zein-Se NPs were tested. The complex structure of zein-Se NPs was deduced by SEM, and the binding mechanism was determined by FT-IR and XPS. The particle size of zein-Se NPs could be regulated from 11.4 ± 0.1 nm to 138.7 ± 0.9 nm under different preparation parameters, the reason for the change in particle size had been speculated. The pH responsiveness and 30-day storage stability of the zein-Se NPs were discussed. The zein-Se NPs still had strong DPPH radical scavenging activity after heat treatment. The zein-Se NPs were cell-friendly and was able to effectively protect cells from H2O2-induced cell-death. This study performed an extensive determination of the underlying physico-chemical properties of zein-Se NPs, we anticipate this approach will open up new possibilities in using natural material to stabilize Se NPs.

Frontoparietal Dysconnection in Covert Bipedal Activity for Enhancing the Performance of the Motor Preparation-Based Brain-Computer Interface.

Motor-based brain-computer interfaces (BCIs) were developed from the brain signals during motor imagery (MI), motor preparation (MP), and motor execution (ME). Motor-based BCIs provide an active rehabilitation scheme for post-stroke patients. However, BCI based solely on MP was rarely investigated. Since MP is the precedence phase before MI or ME, MP-BCI could potentially detect brain commands at an earlier state. This study proposes a bipedal MP-BCI system, which is actuated by the reduction in frontoparietal connectivity strength. Three substudies, including bipedal classification, neurofeedback, and post-stroke analysis, were performed to validate the performance of our proposed model. In bipedal classification, functional connectivity was extracted by Pearson's correlation model from electroencephalogram (EEG) signals recorded while the subjects were performing MP and MI. The binary classification of MP achieved short-lived peak accuracy of 73.73(±7.99)% around 200-400 ms post-cue. The peak accuracy was found synchronized to the MP-related potential and the decrement in frontoparietal connection strength. The connection strengths of the right frontal and left parietal lobes in the alpha range were found negatively correlated to the classification accuracy. In the subjective neurofeedback study, the majority of subjects reported that motor preparation instead of the motor imagery activated the frontoparietal dysconnection. Post-stroke study also showed that patients exhibit lower frontoparietal connections compared to healthy subjects during both MP and ME phases. These findings suggest that MP reduced alpha band functional frontoparietal connectivity and the EEG signatures of left and right foot MP could be discriminated more effectively during this phase. A neurofeedback paradigm based on the frontoparietal network could also be utilized to evaluate post-stroke rehabilitation training.

Fabrication of food grade zein-dispersed selenium dual-nanoparticles with controllable size, cell friendliness and oral bioavailability.

In this study, novel bioavailable selenium nanoparticles with controllable particle size and low toxicity were developed. With selenium modified zein nanoparticles (zein NPs) in-situ, dispersed nano-selenium particles with different structure were formed simultaneously. The particle size, zeta potential, morphology and binding mechanism of synthesized zein-selenium nanoparticles (zein-Se NPs) were systematically discussed. Selenium was considered to be combined with OH and -CO-NH- groups of zein. The selenium in the complex particles presented an amorphous structure with zero valence. The cytotoxicity of zein-Se NPs was significantly lower than that of sodium selenite, even exhibited a growth-promoting effect on normal liver cells (L-02), and were proven to be orally absorbed by organisms in vivo experiments. The difference in particle structure had certain effects on cytotoxicity and oral targeting. The complex particles obtained by this method were anticipated be further used as food fortifiers or medicines.

Mechanisms and research progress of targeted therapies on regulation of autophagy by natural compounds from traditional Chinese medicine / 药学学报

Autophagy is an important physiological process that can degrade cell components and maintain cell homeostasis, divided into three types including macroautophagy, microautophagy and chaperon-mediated autophagy generally, and macroautophagy is the most common form. Autophagy can affect the progression of a variety of diseases, such as cancer, neurodegenerative diseases, heart-related diseases, and autoimmune diseases, etc. However, autophagy can promote or inhibit diseases in different circumstances because of the dual roles of autophagy. Therefore, targeted regulating autophagy may be a potential treatment plan for diseases in specific stages of disease development. Now, with the development of traditional Chinese medicine (TCM) resources and the deepening of researches on the modern utilization of TCM, many active compounds from TCM have been discovered that can target autophagy to exert pharmacological activity. Most of the natural compounds activate or inhibit autophagy by affecting the classical PI3K/AKT/mTOR autophagy pathway. In addition, some compounds can also affect autophagy through MAPKs signaling pathways such as MEK/ERK, JNK and p38MAPK. These active compounds exert various biological activities by regulating autophagy, including anti-tumor, inhibiting neurodegenerative diseases, protecting cardiomyocytes, and relief of inflammatory response. In this review, we summarized the active compounds in TCM that affect autophagy by targeting different signaling pathways and their mechanisms of regulating autophagy, also introduced the effects of active compounds on diseases after affecting autophagy. Finally, this paper summarized and prospected the development of targeted autophagy for the treatment of diseases by TCM compounds, hoping to provide clues for subsequent exploration and research.

Small-molecule compounds with rich sources have diverse structures and activities. The active ingredients in traditional Chinese medicine(TCM) provide new sources for the discovery of new antitumor drugs. Aconitum plants as Chinese medicinal plants have the effects of dispelling wind, removing dampness, warming meridian, and relieving pain. They are mainly used to treat inflammation, pain, rheumatism, and tumors, improve heart function, and dilate blood vessels in clinical practice. Diterpenoid alkaloids are the main active components of Aconitum plants, including C20-, C19-, C18-diterpenoid alkaloids and bis-diterpenoid alkaloids. Stu-dies have demonstrated that diterpenoid alkaloids can effectively treat lung cancer, liver cancer, breast cancer, colon cancer and other cancers. Diterpenoid alkaloids are considered as the most promising natural compounds against cancers. In this review, we summarized the chemical structures and antitumor activities of C20-, C19-, C18-diterpenoid alkaloids and bis-diterpenoid alkaloids extracted from plants of Aconitum, aiming to provide reference for further development of diterpenoid alkaloids from Aconitum as antitumor drugs.

Chinese Medicine as Supporting Therapy for Psoriasis: Past, Present, and Future / 中国结合医学杂志

Psoriasis is a chronic skin disease and an important health concern. Western medicine and therapies are the main treatment strategies for psoriasis vulgaris (PV); however, the overall prognosis of patients with PV is still poor. Therefore, PV prevention is especially crucial. Chinese medicine (CM) has a long history of treating psoriasis, and it has unique wisdom in different cognitive angles and treatment modes from modern medicine. In this review, we first summarized the herbs and ancient CM formulas that have therapeutic effects on PV. Second, the research status and obstacles to the current development of CM in modern medicine were reviewed. Finally, the future of CM in the context of precision medicine and integrated medicine was discussed. After a detailed reading of the abundant literature, we believe that CM, through thousands of years of continuous development and clinical practice, has achieved high effectiveness and safety for PV treatment, despite its surrounding controversy. Moreover, precise analyses and systematic research methods have provided new approaches for the modernization of CM in the future. The treatment of PV with CM is worth popularizing, and we hope it can benefit more patients.

Study on the Diagnostic Value of Contrast-Enhanced Ultrasound and Magnetic Resonance Imaging in Prostate Cancer.

Objective: The aim is to study the different roles of single and joint application of magnetic resonance imaging (MRI) and contrast-enhanced ultrasound (CEUS) in prostate malignant tumors. Methods: 72 patients with prostate masses who underwent CEUS and MRI examination in our hospital from October 2021 and March 2022 were enrolled in this research. The differentially diagnostic roles of CEUS, MRI, and CEUS combined MRI for prostate cancer was assessed on basis of pathological findings as the reference standard. The specificity and sensitivity of the joint application for prostate malignant tumors with various prostate-specific antigen (PSA) levels were also evaluated. Results: The sensitivity of CEUS, MRI, and the joint application for prostate cancer were 72.1%, 74.4%, and 90.7%, respectively. Compared with single application, the sensitivity of CEUS combined with MRI was significantly higher. The specificity of MRI, CEUS, and the combination of the two for prostate cancer were 82.8%, 79.3%, and 89.7%, respectively, and the statistical differences for specificity were not found. The area under ROC curve (AUC) of CEUS combined with MRI in prostate malignant tumor diagnosis was obviously more than that of CEUS and MRI (P < 0.05). CEUS combined with MRI has relative high sensitivity in these patients with different levels of PSA. Conclusions: Contrast-enhanced ultrasound combined with MRI can significantly improve the sensitivity and specificity of prostate cancer diagnosis so that patients can be better diagnosed in advance.

Aromatherapy with single essential oils can significantly improve the sleep quality of cancer patients: a meta-analysis.

OBJECTIVE: To investigate the effect of aromatherapy on sleep quality in cancer patients. METHODS: Published literature on the effect of aromatherapy in cancer patients with sleep disorders in the form of randomized controlled trials (RCTs) were systematically retrieved and screened from PubMed, Cochrane Library, Embase, CBM, CNKI, VIP, and Wanfang databases from inception to November 2021. The methodological quality of the included studies was critically and independently evaluated by two reviewers using the Cochrane Risk of Bias Assessment Tool for RCTs. The correlated data were extracted using the pre-designed form, and all analyses were performed using Reviewer Manager version 5.4. Due to the difference in sleep quality instruments, the data extracted in this study were in the form of standard mean difference (SMD). RESULTS: Ten RCTs included 933 patients (experimental group: 474, control group: 459), and the risk of bias in the included studies was moderate. Aromatherapy could significantly improve the sleep quality of cancer patients [SMD = - 0.79, 95% CI (- 0.93, - 0.66), p < 0.01], especially those with breast cancer [SMD = - 0.98, 95% CI (- 1.57, - 0.40), p < 0.01]. Aromatherapy with single essential oil had a better effect on sleep quality [SMD = -0.94, 95%CI (- 1.25, - 0.62), p < 0.01], of which lavender essential oil had the best effect [SMD = -1.06,95%CI (- 1.49, - 0.63), p < 0.01] while compound essential oils had no effect on sleep quality improvement in cancer patients [SMD = -0.21, 95%CI (- 0.57, 0.14), p = 0.23]. Four of the ten RCTs reported the occurrence of adverse events, of which only one RCT indicated that patients had headache and sneezing while the remaining six did not. CONCLUSIONS: This meta-analysis of 10 RCTs reveals that aromatherapy with single essential oil had a substantial effect on the sleep quality of cancer patients and should be recommended as a beneficial complementary therapy to promote sleep quality in cancer patients.

Development, characterization and in vitro bile salts binding capacity of selenium nanoparticles stabilized by soybean polypeptides.

The paper presents the positive effect of soybean polypeptides (SP) on the stability and the potential hypolipidemic effect of selenium nanoparticles (SeNPs). After preparing SeNPs, SP with different molecular weight were introduced to stabilize SeNPs. We found that the SP with molecular weight >10 kDa (SP5) had the best stabilizing effect on SeNPs. We inferred that the steric resistance resulting from the long chains of SP5 protected SeNPs from collision-mediated aggregation, and the electrostatic repulsions between SP5 and SeNPs also played a positive role in stabilizing SeNPs. The as-prepared SP5-SeNPs were spherical, amorphous and zero valent. It was proved that SeNPs were bound with SP5 through O- and N- groups in SP5, and the main forces were hydrogen bonds and van der Waals forces. The bile salts binding assay showed that the SP5-SeNPs exhibited a high binding capacity to bile salts, which indicated their potential in hypolipidemic application.

Elucidating the anti-aging mechanism of Si Jun Zi Tang by integrating network pharmacology and experimental validation in vivo.

Si Jun Zi Tang (SJZT) is a classic Traditional Chinese Medicine (TCM) prescription used to treat aging-related diseases. However, the potential molecular mechanisms of the anti-aging effects of the bioactive compounds and their targets remain elusive. In this study, we combined network pharmacology and molecular docking with in vivo experiments to elucidate the anti-aging molecular mechanism of SJZT. A series of network pharmacology strategies were used to predict potential targets and therapeutic mechanisms of SJZT, including compound screening, pathway enrichment analysis and molecular docking studies. Based on the network pharmacology predictions and observation of outward signs of aging, the expression levels of selected genes and proteins and possible key targets were subsequently validated and analysed using qRT-PCR and immunoblotting. Using a data mining approach, 235 effective targets of SJZT and aging were obtained. AKT1, STAT3, JUN, MAPK3, TP53, MAPK1, TNF, RELA, MAPK14 and IL6 were identified as core genes in the Protein-Protein Interaction Networks (PPI) analysis. The results of the effective target Gene Ontology (Go) functional enrichment analysis suggested that SJZT may be involved aging and antiapoptotic biological processes. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated that the anti-aging mechanism of SJZT may be associated with the PI3K-AKT and P38 MAPK signalling pathways. Molecular docking analysis suggested that kaempferol and quercetin could fit in the binding pockets of the core targets. In addition, SJZT alleviated the aging symptoms of mice such as osteoporosis and hair loss. In conclusion, the anti-aging effect of SJZT was associated with the inhibition of the PI3K-AKT and P38 MAPK signalling pathways, and these findings were consistent with the network pharmacology prediction.

Effectiveness comparisons of various psychosocial therapies for cancer-related fatigue: A Bayesian network meta-analysis.

OBJECTIVES: The purpose of this network meta-analysis (NMA) is to compare the effect of several psychosocial therapies on CRF critically. METHODS: We applied systematic strategies based on eight databases, namely the Cochrane Central Register of Controlled Trials, PubMed, Embase, PsycINFO, China Biology Medicine (CBM), Wan Fang database, VIP, and China National Knowledge Infrastructure (CNKI) database to preliminary literature retrieval to identify relevant randomized controlled trials (RCTs). Studies, including adult patients (≥18 years) diagnosed with cancer, were eligible regardless of cancer stage and current treatment. We carried out an expression analysis for comparing the efficacy of various psychosocial therapies using Bayesian NMA. A battery of analyses and assessments, such as conventional meta-analysis and risk of bias, were performed concurrently. RESULTS: We identified 41 RCTs including six different psychosocial interventions (4422 participants), namely cognitive-behavioral therapy (CBT), mindfulness-based stress reduction therapy (MBSR), psychoeducational therapy (PE), stress management therapy (SMT), meditation therapy (MT) and comprehensive therapy (CT). Our NMA results showed that three psychosocial intervention therapies were effective for CRF in cancer patients. The most effective psychosocial intervention was MBSR (SMD = -1.23, CrI: -1.88, -0.59, SUCRA = 83.33%), followed by PE (SMD = -0.86, CrI: -1.53, -0.18, SUCRA = 58.51%) and CBT (SMD = -0.84, CrI: -1.31, -0.37, SUCRA = 57.67%). CONCLUSIONS: Our study showed that MBSR was most likely to be the best psychosocial intervention to relieve CRF in cancer patients. Medical staff should pay attention to applying MBSR to cancer patients in future clinical care.

Targeting NAD+: is it a common strategy to delay heart aging?

Heart aging is the main susceptible factor to coronary heart disease and significantly increases the risk of heart failure, especially when the aging heart is suffering from ischemia-reperfusion injury. Numerous studies with NAD+ supplementations have suggested its use in anti-aging treatment. However, systematic reviews regarding the overall role of NAD+ in cardiac aging are scarce. The relationship between NAD+ signaling and heart aging has yet to be clarified. This review comprehensively summarizes the current studies on the role of NAD+ signaling in delaying heart aging from the following aspects: the influence of NAD+ supplementations on the aging heart; the relationship and cross-talks between NAD+ signaling and other cardiac aging-related signaling pathways; Importantly, the therapeutic potential of targeting NAD+ in delaying heart aging will be discussed. In brief, NAD+ plays a vital role in delaying heart aging. However, the abnormalities such as altered glucose and lipid metabolism, oxidative stress, and calcium overload could also interfere with NAD+ function in the heart. Therefore, the specific physiopathology of the aging heart should be considered before applying NAD+ supplementations. We believe that this article will help augment our understanding of heart aging mechanisms. In the meantime, it provides invaluable insights into possible therapeutic strategies for preventing age-related heart diseases in clinical settings.

Synthesis, characterization of tuna polypeptide selenium nanoparticle, and its immunomodulatory and antioxidant effects in vivo.

The tuna polypeptide (TP) was used as the reducing agent and the stabilizing agent to synthesize a tuna polypeptide selenium nanoparticle (TP-SeNP) via a green method. An animal experiment was conducted to investigate its immunomodulatory and antioxidant effects in vivo. The results indicated that the TP regulated the accumulation and stabilization of the TP-SeNP. And the conversion of selenium was tested to be 20.44%. The TP-SeNP was about 22 nm in diameter, a mix of spherical and quasi-spherical, and amorphous. The reaction between the TP and Na2SeO3 was entropy-driven spontaneous, and the binding force was mainly hydrophobic. Intake of the TP-SeNP could greatly increase the phagocytic activity of the mononuclear phagocytic system, and the contents of immunological molecules. The antioxidant capacity of the liver was also improved.

New Proposals for Application of Terahertz Imaging Technique in Chinese Medicine / 中国结合医学杂志

The rapid development of terahertz technology promotes the realization of various terahertz imaging systems. Terahertz technology features terahertz waves as good non-invasive illumination sources due to their high spectral resolution, penetration and safety. The terahertz imaging technique (TIT) has gradually been extended from the biomedical field to the field of Chinese medicine (CM), and it has become a powerful tool for seeking scientific evidence for CM theories with the use of modern science and technology. This paper reviews the current application of TITs in the field of CM research, and most importantly offers novel proposals for the application of TITs in CM research from the perspective of CM syndrome objectification and acupuncture research and cites existing reports as reference to the feasibility of these new proposals.
