[Current status and our consideration on clinical transformation of acupuncture research].

It has become one of the major strategic directions to develop translational medicine and realize the stride leap from basic research to clinical application in the national biomedical field. In recent years, both basic and clinical researches of acupuncture and moxibustion have made landmark progress. However, the transformation of acupuncture and moxibustion techniques still faced with many difficulties, such as low conversion rate and high difficulty of transformation. In this article, we mainly made a preliminary discussion on the current situations of acupuncture and moxibustion transformation from the aspects of basic research content, evidence-based medicine and clinical trials, evaluation criteria for the conclusion of scientific research projects and transformation mode, put forward some existing problems in the transformation process, and proposed some corresponding countermeasures to the problems.

Study on the Specific Expression of Infrared Radiation Temperature on the Body Surface of Acupoint in Rats with Chronic Myocardial Ischemic Injury.

BACKGROUND: Infrared thermal imaging technology was used to observe the changes in infrared radiation temperature at acupoints in rats caused by chronic myocardial ischemia injury. OBJECTIVE: This study aims to compare the difference of body surface infrared radiation temperature information of three groups of acupoints: bilateral Neiguan (PC6), bilateral Yanglingquan (GB33), and bilateral Sham Acupoints (SA) in the pathological state of myocardial ischemia injury, and to explore the relationship between acupoints and viscera state. METHODS: SPF adult Wistar male rats (n = 20) were randomly divided into a control (CTL; n = 10) and an isoproterenol group (ISO; n = 10). Chronic myocardial injury was induced in rats by subcutaneous injection of isoproterenol hydrochloride for 14 d. On the second day after the establishment of the model, the serum levels of cardiac troponin (cTnI) and creatine kinase isoenzyme (CK-MB) were measured by enzyme-linked immunosorbent assay (ELISA). The morphological changes of the myocardial tissue in the two groups were observed by hematoxylin-eosin (HE) staining and their pathological scores were evaluated, which was then used to determine the myocardial ischemic injury. Two days before and after the establishment of the model, the electrocardiograms (ECG) of the two groups of rats were recorded by the (ECG) data acquisition system, and the infrared thermal imaging platform was used to detect the temperature of the six acupoints. RESULTS: 1. After subcutaneous injection of isoproterenol hydrochloride for 14 days, the ST segment of the ECG decreased in the ISO group compared with that of the CTL group; 2. Myocardial tissue injury was serious in the ISO group compared to the CTL group; 3. Serum cTn-I and CK-MB were significantly increased (P <0 01) in the ISO group, compared to that in the CTL group; 4. The infrared radiation temperature on the body surface of bilateral Neiguan (PC6) acupoints decreased significantly in the ISO group, compared to that of the CTL group. CONCLUSION: Infrared thermal imaging technology can be used to detect the changes in the energy state of acupoints. Chronic myocardial ischemic injury can cause a decrease in IR temperature on the body surface of bilateral Neiguan (PC6) acupoints, suggesting that visceral diseases can lead to changes in the energy metabolism of acupoints.

Research progress in targeting autophagy of traditional Chinese medicine and natural compounds to regulate atherosclerosis / 中国中药杂志

Atherosclerosis(AS) is the common pathological basis of many ischemic cardiovascular diseases, and its formation process involves various aspects such as vascular endothelial injury and platelet activation. Vascular endothelial injury is the initiating factor of AS plaque. Monocytes are recruited to differentiate into macrophages at the damaged endothelial cells, which absorb oxidized low-density lipoprotein(ox-LDL) and slowly transform into foam cells. Smooth muscle cells(SMCs) proliferate and migrate continuously. As the only cell producing interstitial collagen fibers in the fibrous cap, SMCs largely determine whether the plaque ruptured or not. The amplifying inflammatory response during the formation of AS recruits platelets to adhere to the damaged area of vascular endothelium and stimulates excessive platelet aggregation. Autophagy activity is associated with vascular lesions and abnormal platelet activation, and excessive autophagy is considered to be a negative factor for plaque stability. Therefore, precise regulation of different types of vascular autophagy and platelet autophagy to treat AS may provide a new therapeutic perspective for the prevention and treatment of atherosclerotic ischemic cardiovascular disease. Currently, treatment strategies for AS still focus on lowering lipid levels with high-intensity statins, which often cause significant side effects. Therefore, the development of safer and more effective drugs and treatment modes is the focus of current research. Traditional Chinese medicine and natural compounds have the potential to treat AS by targeted autophagy, and have been playing an increasingly important role in the prevention and treatment of cardiovascular diseases in China. This paper summarizes the experimental studies on different vascular cell types and platelet autophagy in AS, and sums up the published research results on targeted autophagy of traditional Chinese medicine and natural plant compounds to regulate AS, providing new ideas for further research.

Latent profile analysis of personal values among Chinese college students: associations with mental health disorders and life satisfaction.

Interindividual differences in personal values are prevalent both within and across societies. Interindividual differences in personal value and the relationships with mental health disorders and life satisfaction remain to be holistically considered, especially in China. The present study aims to characterize personal value profiles based on Schwartz's theory model and to examine differences in several mental health-related disorders and life satisfaction potentially across these profiles. Using convenience sampling, a sample of 8,540 Chinese college students (Mage = 18.89, SDage = 2.02, 57.7% male) from three universities completed a questionnaire assessing personal values, internalizing problems, externalizing problems, substance disorders, crime/violence, and life satisfaction. The latent profile analysis identified five personal value profiles, which were labelled as traditional social orientation, open personal orientation, open social orientation, moderate traditional social orientation, and average. Chinese college students in the three social orientation profiles reported low mental health disorders and high life satisfaction. In contrast, students in the personal orientation profile reported high mental health disorders and low life satisfaction. The results indicate the heterogeneity of Chinese college students' personal values and the positive relationship of social-oriented values with mental health and life satisfaction in collectivist cultures.

Current status of neuroimaging research on the effects of acupuncture: a bibliometric and visual analyses.

OBJECTIVE: To conduct an inductive analysis of neuroimaging studies following the global popularity surrounding the effects of acupuncture. METHODS: The relevant works of literature on acupuncture effects-related neuroimaging studies were retrieved from the web of science core collection database from the date of its establishment to 2022. Bibexcel software was used to extract information, such as article numbers, countries, journals, agencies, funding sources and keywords. The VOSviewer software's co-occurrence and clustering module was used for the co-occurrence and cluster analysis of collaborative networks and high frequency keywords, such as authors, institutions and countries. RESULTS: Neuroimaging research on the effects of acupuncture began in the 1960 s and has since received the extensive attention of scholars. China, The United States and South Korea conduct more neuroimaging research on the effects of acupuncture than other countries. Academic journals such as Evidence-Based Complementary and Alternative Medicine, Journal of Alternative and Complementary Medicine, Neural Regeneration Research and Acupuncture in Medicine have published the highest number of acupuncture-related neuroimaging articles. Moreover, cluster analysis differentiates high-frequency keywords into six clusters. Furthermore, the use of the keyword 'density atlas' reveals that neuroimaging research on the effects of acupuncture surrounding pain and neurofunctional rehabilitation is currently the research focus. CONCLUSIONS: This bibliometric study identifies six important research hot spots: Static brain functional connectivity analysis of acupuncture analgesic effects, key theories on the scientific problems of acupuncture, acupuncture analgesic effect of the placebo effect, the neuroimaging of acupoint ST-36, the value of acupuncture in regulating the autonomic nerves and acupuncture therapy as complementary medicine.

Downregulation of lncRNA Miat contributes to the protective effect of electroacupuncture against myocardial fibrosis.

BACKGROUND: Myocardial fibrosis changes the structure of myocardium, leads to cardiac dysfunction and induces arrhythmia and cardiac ischemia, threatening patients' lives. Electroacupuncture at PC6 (Neiguan) was previously found to inhibit myocardial fibrosis. Long non-coding RNAs (lncRNAs) play a variety of regulatory functions in myocardial fibrosis, but whether electroacupuncture can inhibit myocardial fibrosis by regulating lncRNA has rarely been reported. METHODS: In this study, we constructed myocardial fibrosis rat models using isoproterenol (ISO) and treated rats with electroacupuncture at PC6 point and non-point as control. Hematoxylin-eosin, Masson and Sirius Red staining were performed to assess the pathological changes and collagen deposition. The expression of fibrosis-related markers in rat myocardial tissue were detected by RT-qPCR and Western blot. Miat, an important long non-coding RNA, was selected to study the regulation of myocardial fibrosis by electroacupuncture at the transcriptional and post-transcriptional levels. In post-transcriptional level, we explored the myocardial fibrosis regulation effect of Miat on the sponge effect of miR-133a-3p. At the transcriptional level, we studied the formation of heterodimer PPARG-RXRA complex and promotion of the TGF-ß1 transcription. RESULTS: Miat was overexpressed by ISO injection in rats. We found that Miat can play a dual regulatory role in myocardial fibrosis. Miat can sponge miR-133a-3p in an Ago2-dependent manner, reduce the binding of miR-133a-3p target to the 3'UTR region of CTGF mRNA and improve the protein expression level of CTGF. In addition, it can also directly bind with PPARG protein, inhibit the formation of heterodimer PPARG-RXRA complex and then promote the transcription of TGF-ß1. Electroacupuncture at PC6 point, but not at non-points, can reduce the expression of Miat, thus inhibiting the expression of CTGF and TGF-ß1 and inhibiting myocardial fibrosis. CONCLUSION: We revealed that electroacupuncture at PC6 point can inhibit the process of myocardial fibrosis by reducing the expression of lncRNA Miat, which is a potential therapeutic method for myocardial fibrosis.

Comparison of high-dose dual therapy with bismuth-containing quadruple therapy in Helicobacter pylori-infected treatment-naive patients: An open-label, multicenter, randomized controlled trial.

OBJECTIVE: Bismuth-containing quadruple therapy for Helicobacter pylori (H. pylori) eradication has a relatively high rate of side effects and high cost, thus the option of a high-dose dual therapy with a high eradication rate and fewer adverse events is a consideration. However, studies of dual therapy are still scarce and are mostly single-center studies with limited generalizability. Large-scale, multicenter studies are required. Our study investigated and compared the effectiveness, adverse events, patient compliance, and costs of high-dose dual therapy with those of bismuth-containing quadruple therapy in H. pylori-infected treatment-naive patients in a prospective, multicenter, open-label, randomized controlled trial. METHOD: Treatment-naive patients infected with H. pylori were randomly assigned to receive high-dose dual therapy (esomeprazole 20 mg 4 times daily and amoxicillin 1000 mg 3 times daily, for 14 days) or bismuth-containing quadruple therapy (esomeprazole 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and bismuth potassium citrate 220 mg, all twice daily for 14 days). The effectiveness, adverse events, patient compliance, and costs of both groups were compared. RESULTS: A total of 700 patients were enrolled. The high-dose dual therapy group (N = 350) achieved eradication rates of 89.4% (intention-to-treat), 90.4% (modified intention-to-treat), and 90.6% (per-protocol), which were similar to rates in the bismuth-containing quadruple therapy group (N = 350), 84.6%, 88.0%, and 88.2%, respectively (p > 0.05). The high-dose dual therapy group had a lower rate of adverse events (12.9% vs. 28.1%, p < 0.001) and lower costs (¥590.2 vs. ¥723.22) compared with the quadruple therapy group, respectively. The compliance of both groups was satisfactory (97.7% high-dose dual vs. 96.8% quadruple, p > 0.05). CONCLUSION: High-dose dual therapy for H. pylori eradication had similar efficacy and compliance, fewer adverse events, and lower costs than bismuth-containing quadruple therapy for treatment-naive patients.

OBJECTIVES: To study the efficacy of Huaiqihuang granules as adjuvant therapy for bronchial asthma in children. METHODS: A multicenter, prospective, and registered real-world study was performed for the children, aged 2-5 years, who had a confirmed diagnosis of bronchial asthma in the outpatient service of 21 hospitals in China. Among these children, the children treated with medications for long-term asthma control (inhaled corticosteroid and/or leukotriene receptor antagonist) without Huaiqihuang granules were enrolled as the control treatment group, and those treated with medications for long-term asthma control combined with Huaiqihuang granules were enrolled as the combined treatment group. The medical data of all children were collected. Outpatient or telephone follow-up was performed at weeks 4, 8, 12, 20, 28, and 36 after treatment, including asthma attacks and rhinitis symptoms. A statistical analysis was performed for the changes in these indices. RESULTS: There was no significant difference in the frequency of asthma attacks or rhinitis attacks between the two groups before treatment (P>0.05). After treatment, the combined treatment group had significantly lower frequencies of asthma attacks, severe asthma attacks, and rhinitis attacks compared with the control treatment group (P<0.05). There was no signification difference in the incidence rate of adverse reactions between the two groups (P=0.667). CONCLUSIONS: Huaiqihuang granules in addition to medications for long-term asthma control can alleviate the symptoms of bronchial asthma and rhinitis and improve the level of asthma control in children with bronchial asthma, with good safety and little adverse effect.

A missense variant in NDUFA6 confers schizophrenia risk by affecting YY1 binding and NAGA expression.

Genome-wide association studies (GWASs) have revealed that genetic variants at the 22q13.2 risk locus were robustly associated with schizophrenia. However, the causal variants at this risk locus and their roles in schizophrenia remain elusive. Here we identify the risk missense variant rs1801311 (located in the 1st exon of NDUFA6 gene) as likely causal for schizophrenia at 22q13.2 by disrupting binding of YY1, TAF1, and POLR2A. We systematically elucidated the regulatory mechanisms of rs1801311 and validated the regulatory effect of this missense variant. Intriguingly, rs1801311 physically interacted with NAGA (encodes the alpha-N-acetylgalactosaminidase, which is mainly involved in regulating metabolisms of glycoproteins and glycolipids in lysosome) and showed the most significant association with NAGA expression in the human brain, with the risk allele (G) associated with higher NAGA expression. Consistent with eQTL analysis, expression analysis showed that NAGA was significantly upregulated in brains of schizophrenia cases compared with controls, further supporting that rs1801311 may confer schizophrenia risk by regulating NAGA expression. Of note, we found that NAGA regulates important neurodevelopmental processes, including proliferation and differentiation of neural stem cells. Transcriptome analysis corroborated that NAGA regulates pathways associated with neuronal differentiation. Finally, we independently confirmed the association between rs1801311 and schizophrenia in a large Chinese cohort. Our study elucidates the regulatory mechanisms of the missense schizophrenia risk variant rs1801311 and provides mechanistic links between risk variant and schizophrenia etiology. In addition, this study also revealed the novel role of coding variants in gene regulation and schizophrenia risk, i.e., genetic variant in coding region of a specific gene may confer disease risk through regulating distal genes (act as regulatory variant for distal genes).

Acupuncture Treatment for Cough-Variant Asthma: A Meta-Analysis.

BACKGROUND: In recent years, there have been many clinical reports on acupuncture treatment of cough-variant asthma, but no researcher has objectively analysed and evaluated the efficacy and safety of acupuncture treatment of cough-variant asthma from the perspective of evidence-based medicine. OBJECTIVE: To systematically evaluate the clinical efficacy and safety of acupuncture in treating cough-variant asthma and to provide reference values for clinical decision-making. METHODS: The comprehensive computer retrieval Chinese journal full-text database (CNKI), Chinese science and technology periodical database (VIP), ten thousand data knowledge service platform (WanFang Data), PubMed, Embase, and the Cochrane Library were used to collect literature for relevant randomized controlled trials (RCT) of acupuncture treatment of cough-variant asthma, as well as to retrieve papers and add reference retrieval after literature review, in accordance with the standard of literature filtering, data extraction, and quality evaluation. The data were meta-analysed using ReviewManager5.3 software recommended by Cochrane. RESULTS: A total of 11 randomized controlled clinical studies were screened and included, comprising 929 patients. The results of the meta-analysis showed that, compared with the control group, acupuncture intervention on CVA could enhance the total clinical effectiveness rate, reduce the relapse rate of drug withdrawal, relieve symptoms of cough, phlegm, and diaphragmatic congestion, and improve lung function-related indicators and immune inflammation indicators. There were statistically significant differences in all efficacy evaluation criteria. CONCLUSION: The clinical curative effect of acupuncture treatment for cough-variant asthma is precise and has certain advantages in relieving symptoms and reducing the recurrence rate. However, the low quality of the evaluation in the RCT research literature is a problem, and more high-quality clinical randomized controlled trials are needed to further verify the comprehensive clinical efficacy and safety of this treatment.

Optimal exercise parameters of tai chi for balance performance in older adults: A meta-analysis.

BACKGROUND: Tai chi is considered a safe and low-cost treatment for improving balance ability among an older population. However, there is no existing evidence on the optimal exercise parameters of tai chi for improving balance in older adults. OBJECTIVES: To investigate the optimal parameters of a tai chi intervention to improve balance performance of older adults. DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs). SETTING: PubMed, Embase, Cochrane Library, Web of Science, Scopus, China National Knowledge Infrastructure, Wanfang, Chinese Science and Technology Periodical and China Biology Medicine were searched from inception until November 30, 2020. PARTICIPANTS: Adults aged 60 years and over. MEASUREMENTS: Two reviewers independently extracted the data and assessed the quality of the included studies according to the Physiotherapy Evidence Database (PEDro) scale. Subgroup analyses and meta-regressions were conducted to elucidate the impact of tai chi training programs on balance measures. RESULTS: Twenty-six eligible RCTs were included in the meta-analysis. Pooled results showed that tai chi has moderate effects for improving proactive balance (weighted mean standardized mean differences [SMDwm ] = 0.61, 95% CI 0.33-0.89) and static steady-state balance (SMDwm  = 0.62, 95% CI 0.30-0.95) and small effects for improving dynamic steady-state balance (SMDwm  = 0.38, 95% CI 0.03-0.73) and balance test batteries (SMDwm  = 0.47, 95% CI 0.13-0.81) in adults over 60 years of age. The practice frequency could predict the effects of tai chi on static steady-state balance, and the 24-form simplified Yang style tai chi (45-60 min/session, more than four sessions per week and at least 8 weeks) was the most optimal. CONCLUSIONS: Tai chi is effective at improving the balance ability of adults over 60 years of age. A medium duration and high frequency of 24-form tai chi may be the optimal program for improving balance, but this evidence should be recommended with caution due to limitations of the methodology and small sample sizes.

Comparison of Traditional Chinese Exercises and Nontraditional Chinese Exercise Modalities on Cognitive and Executive Function in Community Middle-Aged and Older Adults: A Cross-Sectional Study.

BACKGROUND: Current evidence indicates that regular exercise can have a positive impact on cognitive function in older adults, but whether different exercise modalities may induce differential protective effects in different cognitive domains is uncertain. OBJECTIVE: To compare the effect of traditional Chinese exercise (TCE) modalities and non-traditional Chinese exercise (non-TCE) modalities on cognitive and executive function in community middle-aged and older adults through a cross-sectional study. METHODS: A total of 350 community middle-aged and older adults aged over 55 years participated in this study. Information on demographic characteristics, lifestyle and behavioural habits, and regular exercise was collected by a self-designed questionnaire. Global cognitive ability and executive function were assessed using the Montreal Cognitive Assessment (MoCA) scale, the clock drawing test (CDT), the animal naming test (ANT), and the trail making test (TMT). Eligible subjects were categorized into the no regular exercise (no-RE), non-TCE, or TCE groups according to their self-reported exercise information. Comparisons of global cognitive and executive function among the three groups were conducted using ANOVA or the general linear model with adjustment for potential confounding factors. RESULTS: The results showed that for the non-TCE or TCE groups, the MoCA and CDT scores were significantly higher, and the TMT-A test time was significantly shorter than those in the no-RE group (all P < 0.05), but no significant difference was observed for the TMT-B and ANT tests. After adjustment for potential confounding factors, the MoCA, the CDT, and TMT-A scores in the TCE group were significant compared to those in the no-RE group. In addition, subgroup analysis showed that in the TCE group, the MoCA scores were significantly higher than those in the non-TCE group. Furthermore, in the TCE group, the CDT scores for those with an exercise duration of <5 years were higher and the TMT-A test time for those with an exercise duration of ≥5 years was shorter than those in the non-TCE group. CONCLUSIONS: Both TCE and non-TCE have potential protective effects on global cognitive and executive function in community middle-aged and older adults. Compared to the non-TCE modality, the TCE modality may have a more positive association with these protective effects. Furthermore, prospective studies are needed to confirm these findings.

[Research progress on potential targets-mitochondrial dynamics-related proteins in treatment of myocardial ischemia-reperfusion injury].

Acute myocardial infarction(AMI) is still the leading cause of death worldwide. At present, the treatment of AMI is mainly to restore the cardiac blood supply through myocardial reperfusion. With the widespread use of coronary artery bypass grafting and percutaneous coronary intervention(PCI), myocardial reperfusion injury is a major clinical problem. Mitochondrial dysfunction is an important pathological basis for myocardial ischemic injury. Therefore, mitochondria can be used as an important target against myocardial damage. In this article, we would briefly review the physiological functions of mitochondrial dynamics-related proteins as well as their pathological mechanisms and pharmacological interventions in treatment of myocardial ischemia-reperfusion injury.
