Ultrasonic Nebulization Extraction Coupled with Gas Chromatography-Mass Spectrometry for Analysis of Volatile Components in Traditional Chinese Patent Medicine

The ultrasonic nebulization extraction（UNE） was developed and applied to the extraction of volatile components from traditional Chinese patent medicine Xiaoyao Pills. Several parameters of ultrasonic nebulization extraction including the sample particle size, solvent volume, extraction time and ultrasonic power were studied and selected. As a result, 2.4 g of sample with particle size of 80 mesh was extracted with 15 mL of n-hexane for 20 min at an ultrasonic power of 35 W. The volatile components were analyzed by gas chromatography-mass spectrometry （GC-MS） under the optimal conditions and 57 compounds were identified. The precision, repeatability and stability of the proposed method were also studied. Compared with ultrasonic-assisted extraction（UAE） and hydrodistillation（HD） extraction, the proposed method is more efficient, faster and easier to be operated at room temperature with smaller sample and energy consumption. It is suggested that the ultrasonic nebulization extraction can be used as a novel alternative method for the extraction of volatile components from traditional Chinese patent medicine.

The Essential Role of Zheng Qi in Promoting Health: From the Perspective of Chinese Medicine and Modern Medicine

The concept of Zheng Qi in traditional Chinese medicine (TCM) refers to the vital energy produced by the interaction of Yin and Yang forces in the body. Zheng Qi performs two main functions: Wei Qi (defensive Qi), which shields the body from external pathogens, and Ying Qi (nutritive Qi), which sustains the internal organs and enhances their functionality. In TCM, Chinese tonifying herbs can help restore the balance of Yin/Yang and Qi/Blood function in visceral organs (i.e., optimal physiological functions), thereby fostering the efficient production of Zheng Qi and enhancing health. To ensure the quality of Chinese herbal products, functional assays to measure Yin/Yang, Qi/Blood functions, and Zheng Qi production should be implemented. The efficacy of Yang and Qi herbs can be evaluated by their ability to increase mitochondrial ATP in cultured mouse cardiomyocytes, while Yin and Blood herbs are tested through their immunostimulatory effects on antigen-induced T/B cell proliferation in mouse splenocytes and the production of erythropoietin/nitric oxide in hepatocytes/vascular endothelial cells, respectively. Additionally, Zheng Qi’s effect can be gauged by examining natural killer cell activity and antigen-induced T/B cell proliferation in mice ex vivo. These assays act as biomarkers for assessing the quality and effectiveness of herbal health products within TCM theory.

Applications of HPLC/MS in the analysis of traditional Chinese medicines

In China, traditional Chinese medicines （TCMs） have been used in clinical applications for thousands of years. The successful hyphenation of high-performance liquid chromatography （HPLC） and mass spectrometry （MS） has been applied widely in TCMs and biological samples analysis. Undoubtedly, HPLC/MS technique has facilitated the understanding of the treatment mechanism of TCMs. We reviewed more than 350 published papers within the last 5 years on HPLC/MS in the analysis of TCMs. The present review focused on the applications of HPLC/MS in the component analysis, metabolites analysis, and pharmacokinetics of TCMs etc. 50% of the literature is related to the component analysis of TCMs, which show that this field is the most popular type of research. In the metabolites analysis, HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry has been demonstrated to be the powerful tool for the characterization of structural features and fragmentation behavior patterns. This paper presented a brief overview of the applications of HPLC/MS in the analysis of TCMs. HPLC/MS in the fingerprint analysis is reviewed elsewhere.

Epigastric pain syndrome: What can traditional Chinese medicine do? A randomized controlled trial of Biling Weitong Granules

BACKGROUND Recent research suggests that although prokinetic agents,acid suppressors,and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia(FD),a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions.Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases.The present study was designed to verify the efficacy of Biling Weitong Granules(BLWTG),a traditional Chinese medicinal herbal compound formula,in alleviating epigastric pain syndrome(EPS)in FD patients,in an attempt to provide an effective prescription for the clinical treatment of this disease.AIM To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD.METHODS In this multicenter,stratified,randomized,double-blind,placebo-controlled,parallel group clinical trial,eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk.Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared.RESULTS The baseline demographic data and clinical characteristics,such as epigastric pain symptoms,pain intensity,and frequency of attacks,were matched between the two groups before randomization.After 6 wk of treatment and after the center effect was eliminated,the epigastric pain was significantly improved in 28.33%and 85.59%of the patients in the placebo and BLWTG groups,respectively(P<0.05).At 6 wk,the resolution rate of epigastric pain was 15%and 69.49%in the placebo and BLWTG groups,respectively(P<0.05).The differences of total FD clinical score between these two groups were significant(P<0.05)at 2,4,and 6 wk(P<0.05).The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated(P<0.05).There was no significant difference in the incidence of adverse events between the two groups,and no serious adverse event was noted during the observation.CONCLUSION Compared with placebo,BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.

Research on Combined Rehabilitation Method and Its Mechanism of Traditional Chinese Medicine Daoyin Technique with Biofeedback Technique

Objective: To study an anti resistance active exercise training method which is consistent with the principle of “transcendental goal power” to promote the plasticity change of central nervous system (CNS) in order to recover the motor function after CNS injury, observe its clinical effect and explore its mechanism. Methods: The potential of CNS was induced by six-step Daoyin technique of Chinese medicine, and the potential signal was received in real time by bio-electrical signal receiving equipment and displayed in curve form. Combined with the Operant conditioning biofeedback technique, targeted guidance was given to patients to continuously enhance the action muscle signal intensity and weaken the antagonistic muscle signal intensity, so that the motor program was gradually re-established. Sixty-four patients with hemiplegic elbow dysfunction of old cerebral infarction who had been trained but could not be improved further and had a history of more than 1 year were treated for one course, 90 times and 45 minutes each time. Lovett, Elbow Rom, Fugl-Meyer, program signal intensity and proportion were evaluated before and after treatment. The data were analyzed statistically. Before and after treatment, Lovett MMT, ROM of elbow joint, Fugl Meyer, motor program signal intensity and proportion were assessed, and the data were statistically analyzed. Results: After treatment and before treatment, there was a significant difference between the functional evaluation data (P < 0.01). The function of elbow joint was improved;this is the result of reconstructing the motor program on the basis of developing the potential of CNS by means of the “transcendental goal power” mechanism of the method. There was no recurrence after 6 months of follow-up. Conclusion: The Chinese Medicine Daoyin feedback rehabilitation technique is an effective method to improve elbow joint function of hemiplegia patients with cerebral infarction.

Cerebral mechanism of puncturing at He-Mu point combination for functional dyspepsia: study protocol for a randomized controlled parallel trial

Acupuncture is widely used to treat functional dyspepsia with satisfactory outcomes. Combination of the He and Mu acupoints is commonly used and has a synergistic effect on functional dyspepsia; however, its underlying mechanisms remain unclear. Therefore, a randomized controlled parallel clinical trial is currently underway at Chengdu University of Traditional Chinese Medicine, China. This trial is designed to explore the efficacy of and central responses to the He-Mu point combination in patients with functional dyspepsia using functional magnetic resonance imaging. A total of 105 patients with functional dyspepsia will be allocated into 3 groups： the low-He point group（puncturing at Zusanli（ST36））, Mu point group（puncturing at Zhongwan（CV12））, and He-Mu point combination group（puncturing at ST36 and CV12）. Every participant will receive 20 sessions of manual acupuncture for 4 weeks. The needles will be inserted perpendicularly to a depth of 1 to 2 cun. The angle of rotation and twisting will range from 90 to 180 degrees, while lifting and thrusting will range from 0.3 to 0.5 cm. The various manipulations will be performed 60 to 90 times per minute. The needles will remain in place for 30 minutes, during which manipulation will be applied every 10 minutes. Magnetic resonance imaging will be performed before and after 20 sessions of acupuncture. The primary outcome is symptom improvement according to the Chinese version of the Nepean Dyspepsia Index. Secondary outcomes include the Leeds dyspepsia questionnaire, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Beck Anxiety Inventory, Beck Depression Inventory, and visual analogue scale scores before and after 10 and 20 sessions of acupuncture. Needle sensation and adverse events will be used to assess the therapeutic effects. This study will promote more widespread awareness of the benefits of acupoint combination in the clinical setting and provide a further explanation of the neuromechanism by which acupuncture at the He-Mu point combination for functional dyspepsia.

Analgesic effects of balanced acupuncture versus body acupuncture in low-back and leg pain patients with lumbar disc herniation, as assessed by resting-state functional magnetic resonance imaging

Balanced acupuncture, a single-acupoint balance therapy, regulates the balance of the cerebral center, and is characterized by exerting quick effects and a short treatment course. A total of 20 low-back and leg pain patients with lumbar disc herniation were treated with balanced acupuncture or body acupuncture. Central mechanisms of vaded acupunctures were compared using resting-state functional MRI. Patients from both groups received functional MRI before and after acupuncture. Functional connectivity in brain regions that were strongly associated with the bilatera amygdala was analyzed utilizing AFNI software. Visual analogue scale scores were greater in the balanced acupuncture group compared with the body acupuncture group. Function of the endogenous pain regulation network was enhanced in patients in the balanced acupuncture group, but was not changed in the body acupuncture group. This result indicates that the analgesic effects of body acupuncture do not work through the central nervous system. These data suggest that balanced acupuncture exerts analgesic effects on low-back and leg pain patients with lumbar disc herniation by regulating the function of the endogenous pain regulation network.

Characterization of multiple chemical components of GuiLingJi by UHPLC-MS and ^(1)H NMR analysis

GuiLingJi(GLJ),a classic traditional Chinese medicine(TCM)formula,is composed of over 20 herbs,according to the Pharmacopeia of the People's Republic of China.Owing to its various activities,GLJ has been used in clinical settings for more than 400 years in China.However,the ambiguous chemical material basis limits the development of studies on the quality control and pharmacological mechanisms of GLJ.Therefore,comprehensive characterization of the multiple chemical components of GLJ is of great significance for the modernization of this formula.Given the great variety of herbs in GLJ,both UHPLCMS and ^(1)H NMR techniques were employed in this study.In addition,solvent extraction with different polarities was used to eliminate signal interference and the concentration of trace components.A variety of MS analytic methods were also used,including implementation of a self-built compound database,diagnostic ion filtering,mass defect filtering,and Compound Discoverer 3.0 analysis software.Based on the above strategies,a total of 150 compounds were identified,including 5 amino acids,13 phenolic acids and glycosides,11 coumarins,72 flavones,20 triterpenoid and triterpenoid saponins,23 fatty acids,and 6 other compounds.Moreover,13 compounds were identified by ^(1)H NMR spectroscopy.The UHPLC-MS and ^(1)H NMR results supported and complemented each other.This strategy provides a rapid approach to analyzing and identifying the chemical composition of Chinese herbal prescriptions.The current study provides basis for further research on the quality control and pharmacological mechanism of GLJ.

Effects of acetylcysteine on micro-inflammation and pulmonary ventilation in chronic obstructive pulmonary disease exacerbation

BACKGROUND Acute exacerbation of chronic obstructive pulmonary disease(AECOPD)is a serious complication of chronic obstructive pulmonary disease,often characterized by increased morbidity and mortality.In traditional Chinese medicine,AECOPD is linked to phlegm-heat and blood-stasis,presenting symptoms like thick sputum,fever,and chest pain.It has been shown that acetylcysteine inhalation in conjunction with conventional therapy significantly reduced inflammatory markers and improved lung function parameters in patients with AECOPD,suggesting that acetylcysteine may be an important adjunctive therapy for patients with phlegm-heat-blood stasis type AECOPD.AIM To investigate the effect of acetylcysteine on microinflammation and lung ventilation in patients with phlegm-heat and blood-stasis-type AECOPD.METHODS One hundred patients with phlegm-heat and blood-stasis-type AECOPD were randomly assigned to two groups.The treatment group received acetylcysteine inhalation(10%solution,5 mL,twice daily)along with conventional therapy,whereas the control group received only conventional therapy.The treatment duration was 14 d.Inflammatory markers(C-reactive protein,interleukin-6,and tumor necrosis factor-alpha)in the serum and sputum as well as lung function parameters(forced expiratory volume in one second,forced vital capacity,and peak expiratory flow)were assessed pre-and post-treatment.Acetylcysteine inhalation led to significant reductions in inflammatory markers and improvements in lung function parameters compared to those in the control group(P<0.05).This suggests that acetylcysteine could serve as an effective adjunct therapy for patients with phlegm-heat and blood-stasis-type AECOPD.RESULTS Acetylcysteine inhalation significantly reduced inflammatory markers in the serum and sputum and improved lung ventilation function parameters in patients with phlegm-heat and blood-stasis type AECOPD compared with the control group.These differences were statistically significant(P<0.05).The study concluded that acetylcysteine inhalation had a positive effect on microinflammation and lung ventilation function in patients with this type of AECOPD,suggesting its potential as an adjuvant therapy for such cases.CONCLUSION Acetylcysteine inhalation demonstrated significant improvements in reducing inflammatory markers in the serum and sputum,as well as enhancing lung ventilation function parameters in patients with phlegm-heat and bloodstasis type AECOPD.These findings suggest that acetylcysteine could serve as a valuable adjuvant therapy for individuals with this specific type of AECOPD,offering benefits for managing microinflammation and optimizing lung function.
