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.

Acupuncture Pretreatment Reduces Skeletal Muscle Inflammatory Response in EIMD Rats by Activating cGAS-STING-NF-κB Signaling Pathway.

Acupuncture pretreatment (AP) has a good skeletal muscle protective effect. The present study investigated whether acupuncture pretreatment could improve ultrastructural changes and skeletal muscle inflammation in exercising skeletal muscle injury. Eighty-eight male SD rats were randomly divided into a blank group (C), an exercise group (E), and an acupuncture pretreatment group (AP). Among them, the E and AP groups were divided into five subgroups of 0h, 12h, 24h, 48h, and 72h according to the extraction time after exercise, with 11 groups and eight rats in each group. The study involved simulating skeletal muscle injury caused by intermittent downhill running centrifugal exercise. The researchers used various methods to observe changes in mitochondrial structure and cGAS-STING-NF-κB p65 protein content of classical inflammatory response signaling pathway. These methods included transmission electron microscopy to observe skeletal muscle, Western Blot to detect changes in protein content, and reverse transcription polymerase chain reaction (RT-qPCR method) to detect cytoplasmic mtDNA gene fragment ND1, D-LOOP and cGAS-STING- NF-κB p65 protein RNA. The aim was to investigate the changes in NF-κB p65 protein RNA. Changes in NF-κB p65 protein RNA content and mtDNA gene fragment ND1 and D-LOOP content; changes in serum IL-8 and IFN-ß content were detected by enzyme-linked immunosorbent assay (ELISA); WB, RT-qPCR, ELISA assays aimed to study the skeletal muscle injury and mitochondrial structural damage in group E relationship skeletal muscle tissue level, cytoplasmic mtDNA fragment gene ND1, and D-LOOP content in skeletal muscle tissue of group E. In comparison to group C, the levels of cGAS-STING-NF-κB p65 protein expression and mRNA, and the serum levels of IL-8 and IFN-ß were significantly higher in group E . However, the acupuncture pretreatment group (AP) reduced the extent of damage to skeletal muscle mitochondria and the levels of cytoplasmic mtDNA fragment genes ND1 and D-LOOP. Also, the high expression of cGAS-STING-NF-κB p65 protein, mRNA, and the levels of IL-8 and IFN-ß were inhibited in the AP group. The results indicated that AP ameliorated exercise-induced skeletal muscle injury and reduced skeletal muscle inflammation produced after centrifugal exercise. This was achieved by inhibiting the overexpression of the cGAS-STING-NF-κB signaling pathway.

Effect of mild moxibustion with moxa stick and infrared mild moxibustion on skin blood perfusion at Waiguan (TE 5). / è‰¾æ¡æ¸©å’Œç¸ä¸Žçº¢å¤–çº¿æ¸©å’Œç¸å¯¹å¤–å ³ç©´çš®è‚¤è¡€æµçŒæ³¨é‡çš„å½±å“.

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.

[Current status and trend of acupuncture-moxibustion for myofascial pain syndrome: a visual analysis of knowledge graph based on CiteSpace and VOSviewer].

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.

A user-friendly teaching software for visual analysis of acupoint compatibility laws has been developed based on the principles of partial order mathematics. This software is designed to provide auxiliary teaching of structured organization and visualization of law knowledge of compatibility data of acupuncture and moxibustion prescriptions from ancient texts, textbooks, and clinical case records. The software is installed as a plugin in the Microsoft Office Excel, allowing the generation of visually appealing graphs and associated rules that align with the cognitive patterns of teachers and students majoring in acupuncture and moxibustion. Its aim is to facilitate the discovery and analysis of underlying patterns and structured knowledge embedded in acupoint compatibility data, thus contributing to the enhancement of teaching effectiveness in acupoint compatibility.

Quantitative analysis of the Tuina manipulation parameters based on Ding's rolling manipulation.

BACKGROUND: In the present scenario, there is no unified measurement standard for the five basic requirements of the Tuina manipulation, such as "lasting, uniform, gentle, powerful and penetrating", and the descriptions that are solely based on the words are difficult to interpret. As a result, a quantitative study of the Tuina manipulation can aid in the development of a unified standard for Tuina manipulation, thereby assisting the transmission and advancement of the Tuina science. OBJECTIVE: Using the Tuina manipulation data gloves and data collection system, and taking Ding's rolling manipulation as the research object, the present study explored the necessity and significance of quantitative research on the inheritance and development of traditional Tuina manipulation. METHODS: Using the Tuina experts as the research object, the manipulation characteristics and parameter signs of Ding's rolling manipulation were collected and analyzed by employing the "Tuina manipulation data gloves and data collecting system". RESULTS: ⟀ The force waveforms, peaks and minima of each detection point altered regularly, and the force values of the front and back pendulum waveforms varied significantly with small differences in the waveform height. ⟁ The Tuina force values of the experts were concentrated in 0.70-0.85 kg, the frequency was concentrated at 120-160 times/min, and the period was about 0.4 s. ⟂ The peak, minimum, and mean of the ai1 channel was greater than ai4, all of which were statistically significant (P< 0.05). The ai6 peak, minimum, and mean were greater than ai3 and statistically significant (P< 0.05). The ai2 peak was greater than ai5, which was not statistically significant (P> 0.05). The ai2 minimum was greater than ai5, and the ai2 mean was less than ai5, all of which were statistically significant (P< 0.05). CONCLUSION: It was found that the objectification studies of the experts performing Tuina practices should be based on real clinical process. Furthermore, the results of the quantitative study can present the quantitative characteristics of the expert's parameters, as well as the details of the manipulation process. Thus, the quantitative study of the parameters is of great significance in the transmission and development of the expert's manipulation.

Clinical studies on the electric automatic massage therapy for recovery of acute sports fatigue.

BACKGROUND: Acute sports fatigue impairs athletes' performance and causes other health issues; therefore, an effective method of relieving acute sports fatigue is being researched. OBJECTIVE: The present study was envisaged to evaluate the effect of electric auto-massage therapy and proprioceptive neuromuscular facilitated (PNF) stretching method on the recovery of acute exercise fatigue using the heart rate variability-based multi-physiological index and RPE scale, and to explore the underlying principle and mechanism. METHOD: Sixty volunteers were divided into the stretching group, massage group and control group (20 subjects each) using the complete randomization method. The massage group chose the kneading, pressing, tapping and patting techniques using the intelligent massage chair to intervene on the volunteers, the stretching group chose the PNF stretching method to intervene on the volunteers, while the control group did not adopt any of these techniques. The Rating Of Perceived Exertion (RPE) score, heart rate (HR), grip strength, skin electrical activity, heart rate variability (HRV) and blood oxygen saturation (SpO2) of the three groups were recorded before and after the intervention. RESULTS: Before the intervention, there was no statistically significant difference between the values of heart rate variability (HRV) in the three groups (P> 0.05), while after the intervention, there was a statistically significant difference between the values of heart rate variability - low frequency/high frequency (HRV (LF/HF)) and HRV (HF) in the three groups as: HRV (HF): ηH2= 0.10; P= 0.022; HRV (LF/HF): ηH2= 0.44; P= 0.001. The results indicated that the different intervention methods presented substantial effects on the values of HRV (HF) and HRV (LF/HF) in the volunteers. The HRV (HF) values of massage group, stretching group and control group were compared, and the difference between the massage group and control group was statistically significant (P= 0.019). Further, the HRV (HF) values of massage group rose more significantly than control group after the intervention, and the difference between HRV (HF) values of massage group and stretching group was not statistically significant. When comparing the HRV (LF/HF) values of massage group, stretching group and control group, the differences between the massage group and stretching group and control group were statistically significant (P= 0.001, P< 0.05), and it was observed that the HRV (LF/HF) values of massage group decreased more significantly than those of stretching group and control group after the intervention. The difference in HRV (LF) values between the three groups after the intervention was not statistically significant (P> 0.05). CONCLUSION: 1. It was observed that the electric automatic massage therapy played a vital role in the rapid relief of exercise fatigue by soothing and regulating the human phototropic system, reducing vagal tone, and accelerating the excretion of metabolites; while PNF stretching relieved the exercise fatigue by providing physical and verbal communication to transfer the perception of fatigue, and by promoting the excretion of metabolites through muscle isometric contraction. 2. The effect of electric auto-massage therapy was marginally stronger than the commonly used PNF stretching exercise method.

Clinical efficacy of vibration stimulation therapy to relieve acute exercise fatigue.

BACKGROUND: Previous studies showed that local vibration stimulation therapy was effective in relieving fatigue, and the effects of different modes of vibration stimulation therapy were further investigated. OBJECTIVE: This study aimed to examine the effects of different vibration stimulation modes on relieving acute exercise fatigue based on the multiphysiological indicators such as heart rate variability (HRV), skin conductance level (SCL), and ratings of perceived exertion (RPE) subjective scale. METHODS: Sixty participants selected from the dragon boat team of the Shanghai University of Traditional Chinese Medicine were divided into acupoint stimulation group (20 participants), muscle stimulation group (20 participants), and control group (20 participants) by complete randomization. RESULTS: (1) RPE: both stimulation groups showed a significant increase compared to the control group. (2) Heart rate values: the difference between muscle stimulation group and control group was statistically significant; (3) SCL: the two stimulation groups had significantly higher and statistically significant differences in SCL (max) and SCL (mean) values compared to the control group; the muscle stimulation group had statistically significant differences in SCL (min) compared to the control group, and the acupoint stimulation group had statistically significant differences in SCL (v) compared to the control group; (4) HRV (hf): The difference between the acupoint stimulation group and the muscle stimulation group was statistically significant. CONCLUSION: (1) Both stimulation groups are part of vibration therapy, which can relieve sympathetic tension and regulate the vegetative nervous system's relaxation effect. (2) The meridian-vessel theory may be related to the acupoint stimulation group. The low-level visceral regulation centers in the spinal nerve segment region, where the acupoints are located, trigger changes in autonomic tone and enhance parasympathetic nerve activity to relieve acute motor fatigue. (3) The muscle stimulation group may be due to the 30-Hz vibration frequency's ability to raise muscle epidermal temperature, which increases blood flow and reflexively inhibits sympathetic excitation.

[Design and development of a novel infrared mild moxibustion device].

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.

OBJECTIVES: To observe the effects of acupuncture pretreatment on toll-like receptor 9/myeloid differentiation factor 88/nuclear factor-κB (TLR9/MyD88/NF-κB) signaling pathway and inflammatory response in the rats with exercise-induced skeletal muscle damage (EIMD) and explore the underlying mechanism of this pretreatment for EIMD. METHODS: A total of 88 male SD rats were randomly divided into a blank group (8 rats), a model group (40 rats) and an acupuncture pretreatment group (40 rats). In the model group and the acupuncture pretreatment group, 5 subgroups were randomized according to the sampling time of 0, 12, 24, 48 and 72 h of modeling, with 8 rats in each one, respectively. Before modeling, in the acupuncture pretreatment group, acupuncture was delivered at bilateral "Zusanli" (ST 36) and "Guanyuan" (CV 4) for 20 min, once daily for consecutive 7 days. By one-time intermittent downhill centrifugal exercise on animal experimental treadmill, EIMD model was established in the model group and the acupuncture pretreatment group. The ultrastructure of gastrocnemius muscle was observed under transmission electron microscope. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the serum were detected by ELISA. The protein and mRNA expression of TLR9, MyD88 and NF-κB p65 in the gastrocnemius tissue of rats was detected by the Western blot and real-time PCR, respectively. RESULTS: Compared with the blank group, the gastrocnemius ultrastructure in the model group showed the damage of different degrees, with myofilaments disarranged and twisted, mitochondria obviously swollen and mitochondrial crista partially defected. Compared with the model group, the injury was mild, most of muscle fibers were arranged neatly and the number of mitochondria increased remarkably in the acupuncture pretreatment group. Compared with the blank group, in the model group, the serum IL-6 levels increased at 0, 12, 24 and 48 h after modeling in the rats (P<0.01), and TNF-α levels were elevated at each time point after modeling (P<0.05, P<0.01). In the acupuncture pretreatment group, the serum IL-6 levels were reduced at 12, 24 and 48 h after modeling (P<0.01, P<0.05), and the TNF-α levels decreased at 24, 48 and 72 h after modeling (P<0.01) when compared with those in the model group at the same time points separately. The serum IL-6 and TNF-α levels ascended and then tended to decline in the model group and the acupuncture pretreatment group. Compared with the blank group, the protein and mRNA expression of TLR9 and NF-κB p65 in the gastrocnemius tissue increased at 12, 24, 48 and 72 h after modeling (P<0.01, P<0.05), and the protein and mRNA expression levels of MyD88 in the gastrocnemius tissue at each time point after modeling were elevated (P<0.05, P<0.01) in the model group. When compared with the model group at the same time points, in the acupuncture pretreatment group, the protein expression of TLR9 in the gastrocnemius tissue decreased at 12, 24, 48 and 72 h after modeling (P<0.05, P<0.01), and the mRNA expression of TLR9 was declined at 24, 48 and 72 h after modeling (P<0.01, P<0.05); the protein and mRNA expression of MyD88 in the gastrocnemius decreased at 24, 48 and 72 h after modeling (P<0.01, P<0.05), and that of NF-κB p65 was reduced at 24 h and 48 h after modeling (P<0.01). The protein and mRNA expression of TLR9, MyD88 and NF-κB p65 in the gastrocnemius tissue showed a trend of decrease after increase in the model group and the acupuncture pretreatment group. CONCLUSIONS: Acupuncture pretreatment can alleviate exercise-induced skeletal muscle damage, which may be related to modulating the expression of TLR9/MyD88/NF-κB signaling pathway to inhibit the inflammatory response.

[Development of teaching training and assessment system for warming acupuncture].

A teaching training and assessment system for warming acupuncture is developed. This system is suitable for the technique operation of multi-acupoint warming acupuncture, and could evaluate the training effects of warming acupuncture at each acupoint. The hardware structure of this system is mainly composed of man-machine interface, control unit and training unit. The software program includes reset module, system clock module, needle depth signal control module, vibration control module and communication module.

Each training unit is relatively independent, and relevant parameters are set separately; the relevant parameters information is displayed in real time. The parameters of training unit includes needling time, vibration frequency and vibration time. In conclusion, the teaching training and assessment system for warming acupuncture could be used in the teaching and assessment of warming acupuncture. According to the criteria including operation time and effect, the students' technique ability of warming acupuncture could be evaluated objectively, which is helpful to set teaching objectives and technical operation requirements in warming acupuncture teaching.

Effect of different twirling and rotating acupuncture manipulation techniques on the blood flow perfusion at acupoints.

OBJECTIVE: To analyze the effect of different twirling and rotating acupuncture manipulation techniques on the blood flow perfusion at acupoints to provide a reference for the study of acupoint specificity and the quantification and effectiveness of acupuncture methods. METHODS: Twenty healthy male or female college students each received four different acupuncture manipulation techniques, including simple acupuncture, uniform reinforcing-reducing needling, twirling reinforcing needling, and twisting reducing needling. The self-control method was applied. Acupuncture was performed by an acupuncture manipulation simulator at Neiguan (PC 6) and Zusanli (ST 36). The process of twirling and rotating was divided into seven timepoints. The PeriCam Perfusion Speckle Imager (PSI) System was used to collect the blood flow perfusion data at each acupoint. The specificity of twirling and rotating acupuncture manipulation was analyzed based on changes in the curve, video, and numerical blood flow perfusion data at each timepoint. RESULTS: There were two peaks in the blood flow perfusion curve of twirling and rotating acupuncture manipulation; one appeared after 3 min of needle retention, and the other appeared 3 min after needle removal. The blood flow perfusion parameters showed that the greatest differences between the four manipulation techniques occurred after 5 and 10 min of needle retention. The specificity of various manipulation techniques was most obvious at these two timepoints. There were significant differences between the four manipulation groups in the blood flow perfusion and the relative change rates of blood flow perfusion at each timepoint. CONCLUSION: Laser speckle imaging enables the real-time, non-invasive, rapid, and accurate collection of blood flow perfusion data during acupuncture. This imaging technique enables the easy attainment of various parameters such as visual images, two-dimensional curves, and data tables. At various timepoints, the four groups significantly differed regarding changes in blood flow perfusion and relative change rates of blood flow perfusion, which facilitated the differentiation of the four acupuncture manipulation methods. Based on this, further analysis could be conducted to study spatial distribution characteristics such as the influence area and flare area. The frequency domain analysis of acupuncture manipulation curves is important in the study of the dose-effect relationship and specificity of acupuncture manipulation.

Draft genome of the peanut A-genome progenitor (Arachis duranensis) provides insights into geocarpy, oil biosynthesis, and allergens.

Peanut or groundnut (Arachis hypogaea L.), a legume of South American origin, has high seed oil content (45-56%) and is a staple crop in semiarid tropical and subtropical regions, partially because of drought tolerance conferred by its geocarpic reproductive strategy. We present a draft genome of the peanut A-genome progenitor, Arachis duranensis, and 50,324 protein-coding gene models. Patterns of gene duplication suggest the peanut lineage has been affected by at least three polyploidizations since the origin of eudicots. Resequencing of synthetic Arachis tetraploids reveals extensive gene conversion in only three seed-to-seed generations since their formation by human hands, indicating that this process begins virtually immediately following polyploid formation. Expansion of some specific gene families suggests roles in the unusual subterranean fructification of Arachis For example, the S1Fa-like transcription factor family has 126 Arachis members, in contrast to no more than five members in other examined plant species, and is more highly expressed in roots and etiolated seedlings than green leaves. The A. duranensis genome provides a major source of candidate genes for fructification, oil biosynthesis, and allergens, expanding knowledge of understudied areas of plant biology and human health impacts of plants, informing peanut genetic improvement and aiding deeper sequencing of Arachis diversity.

[Establishment of pharmacological evaluation system for non-nucleoside reverse-transcriptase inhibitors resistant HIV-1].

Consistent non-nucleoside reverse-transcriptase inhibitors (NNRTIs) resistant HIV-1 strains occurred due to the clinical use for more than ten years of efavirenz (EFV), nevirapine (NVP), and delavirdine (DLV). In this study, we established nine cell-based pharmacological models according to most NNRTIs-resistant clinical tested strains, Resistant mutations were introduced into vector, pNL4-3.Luc.R-E-, by overlapping PCR. Then, pseudovirions were produced by co-transfection of VSV-G plasmid and pNL4-3.Luc.R-E- -mut. All nine recombinant VSVG/HIV-mut pseudovirions (VSVG/HIV-wt, VSVG/HIV(-K103N), VSVG/HIV(-Y181C), VSVG/HIV(-L100I,K103N), VSVG/HIV(-Y188L), VSVG/HIV(-K103N,Y181C), VSVG/HIV(-K103N,P225H), VSVG/HIV(-K103N,Y188L), VSVG/HIV(-K103N,G109A) and VSVG/HIV(-K103N,V108I)) had high efficient infectivity. Furthermore, they all showed resistant characteristics to EFV and NVP with IC50 changes consisting with clinical reports, not to nucleoside reverse-transcriptase inhibitors (AZT and d4T). This series safe cell-based model, which could be carried out in BSL-2 laboratory, can be used for evaluating NNRTIs candidates.
