The associations between functional dyspepsia and potential risk factors: A comprehensive Mendelian randomization study.

BACKGROUND: Previous cross-sectional studies have identified multiple potential risk factors for functional dyspepsia (FD). However, the causal associations between these factors and FD remain elusive. Here we aimed to fully examine the causal relationships between these factors and FD utilizing a two-sample MR framework. METHODS: A total of 53 potential FD-related modifiable factors, including those associated with hormones, metabolism, disease, medication, sociology, psychology, lifestyle and others were obtained through a comprehensive literature review. Independent genetic variants closely linked to these factors were screened as instrumental variables from genome-wide association studies (GWASs). A total of 8875 FD cases and 320387 controls were available for the analysis. The inverse variance weighted (IVW) method was employed as the primary analytical approach to assess the relationship between genetic variants of risk factors and the FD risk. Sensitivity analyses were performed to evaluate the consistency of the findings using the weighted median model, MR-Egger and MR-PRESSO methods. RESULTS: Genetically predicted depression (OR 1.515, 95% confidence interval (CI) 1.231 to 1.865, p = 0.000088), gastroesophageal reflux disease (OR 1.320, 95%CI 1.153 to 1.511, p = 0.000057) and years of education (OR 0.926, 95%CI 0.894 to 0.958, p = 0.00001) were associated with risk for FD in univariate MR analyses. Multiple medications, alcohol consumption, poultry intake, bipolar disorder, mood swings, type 1 diabetes, elevated systolic blood pressure and lower overall health rating showed to be suggestive risk factors for FD (all p<0.05 while ≥0.00167). The positive causal relationship between depression, years of education and FD was still significant in multivariate MR analyses. CONCLUSIONS: Our comprehensive MR study demonstrated that depression and lower educational attainment were causal factors for FD at the genetic level.

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.

Causal relationships between psychological disorders and functional gastrointestinal disorders: a bidirectional two-sample Mendelian randomization study.

BACKGROUND AND AIMS: Observational studies have shown bidirectional associations between psychological disorders (e.g. depression and anxiety) and functional gastrointestinal disorders. However, whether the relationships are causal is uncertain. Here, we used a bidirectional two-sample Mendelian randomization method to investigate the association between psychological disorders and functional gastrointestinal disorders (FGIDs). METHODS: We obtained genome-wide association study summary statistics for two common psychological disorders: depression (170 756 cases) and anxiety (31 977 cases), as well as for three common FGIDs: functional dyspepsia with 6666 cases, constipation with 26 919 cases, and irritable bowel syndrome (IBS) with 7053 cases. These summary statistics were retrieved from several publicly available genome-wide association study databases. The inverse variance weighted method was used as the main Mendelian randomization method. RESULTS: Inverse variance weighted Mendelian randomization analyses showed statistically significant associations between genetically predicted depression and risk of functional dyspepsia [odds ratio (OR): 1.40, 95% confidence interval (CI): 1.08-1.82], constipation (OR: 1.28, 95% CI: 1.13-1.44), and IBS (OR: 1.51, 95% CI: 1.37-1.67). Genetically predicted anxiety was associated with a higher risk of IBS (OR: 1.13, 95% CI: 1.10-1.17) instead of functional dyspepsia and constipation. In addition, genetically predicted IBS instead of functional dyspepsia and constipation was associated with a higher risk of depression (OR: 1.33, 95% CI: 1.12-1.57) and anxiety (OR: 2.05, 95% CI: 1.05-4.03). CONCLUSION: Depression is a causal risk factor for three common FGIDs. A bidirectional causal relationship between IBS and anxiety or depression was also identified.

Electroacupuncture treatment for pancreatic cancer pain: a randomized controlled trial.

BACKGROUND: Pancreatic cancer is often accompanied by severe abdominal or back pain. It's the first study to evaluate the analgesic effect of electroacupuncture on pancreatic cancer pain. A randomized controlled trial compared electroacupuncture with control acupuncture using the placebo needle. METHODS: Sixty patients with pancreatic cancer pain were randomly assigned to the electroacupuncture group (n = 30) and the placebo control group (n = 30). Patients were treated on Jiaji (Ex-B2) points T8-T12 bilaterally for 30 min once a day for 3 days. Pain intensity was assessed with numerical rated scales (NRS) before the treatment (Baseline), after 3 treatments, and 2 days follow-up. RESULTS: Baseline characteristics were similar in the two groups. After 3 treatment, pain intensity on NRS decreased compared with Baseline (-1.67, 95% confidence interval [CI] -1.46 to -1.87) in the electroacupuncture group; there was little change (-0.13, 95% CI 0.08 to -0.35) in control group; the difference between two groups was statistically significant (P < 0.001). Follow-up also found a significant reduction in pain intensity in the electroacupuncture group compared with the control group (P < 0.001). CONCLUSIONS: Electroacupuncture was an effective treatment for relieving pancreatic cancer pain.

Analysis of biomechanical characterization of the thumb rubbing method.

BACKGROUND: Thumb rubbing is one of the widely accepted massage techniques, owing to its simple and effective operation. Exploring the biomechanical characteristics of the thumb rubbing method can assist the understanding of the operating characteristics of manipulation, thereby improvising the therapeutic role of manipulation. OBJECTIVE: To study the kinematic and kinetic characteristics of the thumb kneading method from the biomechanical point of view, and to quantitatively analyze the key points of thumb kneading operation. METHODS: We explored the biomechanical characteristics of the thumb kneading operation by an analysis of the parameters scored by the experts and students using the "thumb kneading data glove and data collection system". RESULTS: (1) Force trajectory: The expert group showed a regular force trajectory compared to the student group, with a stable thumb suction position, small drift and concentrated force. (2) Force value: The average force value of the expert group was concentrated in the range 0.614 ± 0.041 kg, while the average force value of the student group was concentrated in the range 0.650 ± 0.146 kg and the difference was not statistically significant. (3) Frequency: The frequency of the expert group was mainly concentrated in the range 134.280 ± 39.106 times/min, while that of the student group was 66.04 ± 23.651 times/min, (P< 0.05). (4) Period: The operation cycle during the thumb kneading of the expert and student groups was mainly concentrated in the range of 0.476 ± 0.117 s and (0.990 ± 0.259) s, respectively, and the difference was statistically significant (P< 0.05). CONCLUSION: The present study revealed that the technical operation of the expert group was more stable and standardized than that of the student group. It was found that the force value was inversely proportional to the frequency of the operation. In the "circular rotation" operation of the thumb rubbing method, the force value conversion degree of different parts of the thumb reflected the motion trajectory. Furthermore, the "circular rotation" operation performed by the expert group was better than the student group. The study of the parameters, including the angle of frequency, period and force value can reflect the biomechanical characteristics of thumb rubbing method to a significant extent.

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.

[Development and application of visual analysis teaching software for acupoint compatibility laws].

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.

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.

[Thoughts on and probes into computer simulation of acupuncture manipulation].

The studies of the simulation of acupuncture manipulation mainly focus on mechanical simulation and virtual simulation (SIM). In terms of mechanical simulation, the aim of the research is to develop the instruments of the simulation of acupuncture manipulation, and to apply them to the simulation or a replacement of the manual acupuncture manipulation; while the virtual simulation applies the virtual reality technology to present the manipulation in 3D real-time on the computer screen. This paper is to summarize the recent research progress on computer simulation of acupuncture manipulation at home and abroad, and thus concludes with the significance and the rising problems over the computer simulation of acupuncture manipulation. Therefore we put forward that the research on simulation manipulation should pay much attention to experts' manipulation simulation, as well as the verification studies on conformity and clinical effects.

[Development of handshape tuina-cupping instrument based on pulsating airflow technology].

A new type of handshape tuina-cupping instrument is developed to overcome the shortcomings of traditional cupping therapy, such as indentation and pain, and simulates the tuina manipulation, so as to realize the combination of cupping therapy and tuina manipulation. The handshape tuina-cupping instrument has a trumpet-shaped, silica gel edge. At the same time, the finger-belly shape is added at the cupping edge to simulate the shape of fingers during tuina. Under the action of air suction and deflation of pulsating airflow, the purpose of simulating tuina manipulation is achieved, and the indentation and pain caused by the handshape tuina-cupping instrument is significantly less than that of the traditional cupping instrument.

RESULTS: The contrast experiment with mercury thermometer measurement showed that the temperature measurement curve of the designed acupoint temperature data collection platform was highly consistent with that of the standard thermometer, which verified the stability and reliability of the designed temperature measurement platform. The experiment of animal in-vivo measurement showed that the acupoint temperature probe had good feasibility for in-vivo acupoint temperature measurement. CONCLUSION: Acupoint temperature probe and acupoint temperature data collection technology can measure the temperature inside acupoints, and ensured the accuracy and veracity of the results. As an experimental method of acupoints temperature parameter collection, it can quantitatively record the temperature changes during the acupuncture treatment.

[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. The teaching training and assessment system of warming acupuncture adopted touch-screen human-machine interface, which is simple to operate. The basic training unit, through multi-angle and multi-dimension adjustment of universal base, could realize the simulation training of warming acupuncture at different acupoints and angles of human body. 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.

Motion video-based quantitative analysis of the 'lifting-thrusting' method: a comparison between teachers and students of acupuncture.

OBJECTIVE: To compare objective measures of needle manipulation between students and teachers of acupuncture using motion video analysis technology, to help support instructional acupuncture education. METHODS: A total of 30 teachers and 60 students participated in this study. Acupuncture needles were inserted at LI11 and motion videos were recorded for three subtypes of 'lifting-thrusting' manipulation: (1) 'mild reinforcing-attenuating'; (2) 'reinforcing'; and (3) 'attenuating'. The videos were analysed using Simi Motion 3D software to acquire the movement parameters of four trace marks: 'thumb tip'; 'forefinger tip'; 'forefinger middle joint'; and 'forefinger base joint'. Differences between the two groups were compared using t-tests, X2 tests and/or rank-sum tests. RESULTS: Changes in the near-end interphalangeal joint were positively associated with a range of movement along the X axis. Motion parameters for the thumb tip, the proximal interphalangeal (PIP) joint of the forefinger and the X axis shaft swing near the end of the forefinger in the teacher group were higher than those in the student group. The teacher group featured smaller trough dispersion and smaller crest dispersion during 'reinforcing' and 'attenuating' manipulations, respectively. CONCLUSIONS: The 'lifting-thrusting' manipulation could be simplified as a fixed-axis rotation using metacarpophalangeal joints in the thumb and forefinger as the shaft centre. Teachers opened at a larger angular variation for the PIP during the lifting and thrusting processes with better spatial control. Temporal control was similar between groups and therefore appears easier to grasp. Repetitive training might be helpful for improving athletic and spatial stability during needle manipulation.

[Teaching exploration and practice of research experiment of experimental curriculum in Principle and Application of Acupuncture-Moxibustion Equipment].

In order to improve students' ability of performing investigative study, promote practical teaching, optimize teaching philosophy and methods, we integrated the subject frontier dynamics and development achievements and knowledge into teaching content, the teaching exploration and practice of research experiment of experimental curriculum in Principle and Application of Acupuncture-Moxibustion Equipment was performed. The experimental curriculum was used as starting point. Before experimental teaching, the learning of knowledge was completed by theoretical study and key self-study points. During experimental teaching, experimental report and analysis report were completed by group collaboration. After experimental teaching, the research experiment was reported, analyzed and summarized by group discussion and presentation. With innovate, flexible and diverse teaching forms to guide the students to experience the process of "asking questions→conducting experiment→observation→recording→analysis→conclusion→verification of assumptions-discussion→reports", the ability of independent thinking and active investigation was improved; teaching level and teaching effectiveness were promoted.

[Quantitative research on effects of electroacupuncture on different parameters on analgesia in rats with adjuvant-induced arthritis].

To research the effects of electroacupuncture on different quantitative parameters on analgesia in rats with adjuvant-induced arthritis. Rats of adjuvant-induced arthritis were treated by electroacupuncture with different waveforms. Pain threshold and swelling degree of joint were observed. Electroacupuncture parameters being selected were measured by frequency spectrum analysis. After treatment, the pain thresholds in the electroacupuncture groups with different waveforms were higher than that of the model group (P < 0.05, P < 0.01); the local swelling degree of inflammation of the electroacupuncture groups were higher than that of the model group (P < 0.01), but was lower than that of the control group (P < 0.05, P < 0.01). Frequency, current, voltage and pulse width of successive wave and intermittent wave were similar. Frequency,current, voltage and pulse width of sound electric wave changed continuously. The results were that all the electroacupuncture with different waveforms had the analgesic effect in rats with adjuvant-induced arthritis and the therapeutic effect of the electroacupuncture of sound electric wave was the best. It is reasonable and important that electroacupuncture parameter should be quantified.

The device can objectively help warm-acupuncture training and evaluation so as to promote its clinical standardization manipulation.

[Research on real-time data collection and demonstration system for acupuncture manipulation].

OBJECTIVE: To apply the real-time data collection and demonstration system for acupuncture manipulation to quantitative analysis of acupuncture manipulation for acupuncture teaching and research. METHODS: The real-time observation and analysis of parameter changes of acupuncture manipulation were implemented by this system. RESULTS: During the course of lifting and thrusting manipulation, the needle body moved in a uniform variable motion, and the action force was still kept while the arrival of Qi was achieved. During the course of twirling manipulation, the variations of twirling number and radian caused the changes of resistance moment, and this reaction was related to the body response. During the course of rotating and shaking manipulation, the radius for rotating and shaking was related to such factors as the force, the action point and the direction. CONCLUSION: The real-time data collection and demonstration system for acupuncture manipulation can provide a new experimental method for quantitative data analysis, standardized research and teaching demonstration of acupuncture.
