OBJECTIVES: To explore the effect mechanism of moxibustion with wheat-grain size cone at "Zusanli" (ST 36) on vascular injury and oxidative stress in hyperlipidemia through mammalian target of rapamycin (mTOR)/hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) signaling pathway. METHODS: Forty healthy male SD rats with SPF grade were randomly divided into a normal group, a model group, a moxibustion group, and an inhibitor group, with 10 rats in each one. The hyperlipidemia model was established by feeding a high-fat diet for 8 weeks in rats of the model group, the moxibustion group and the inhibitor group. The moxibustion with wheat-grain size cone was delivered at bilateral "Zusanli" (ST 36) of each rat in the moxibustion group and the inhibitor group, with 3 cones on each acupoint in each intervention, once daily for 4 weeks. In the inhibitor group, before each intervention with moxibustion, rapamycin solution was injected intraperitoneally, 2.0 mg/kg. After modeling and intervention, using ELISA, the levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in the serum of rats were determined. After intervention, with HE staining and oil red O staining adopted, the abdominal aortic morphology and peripheral lipid deposition were observed. Separately, using WST-1, TBA and micro-plate method, the superoxide dismutase (SOD) activity and the levels of malondialdehyde (MDA) and nitric oxide (NO) in the serum were detected. The protein expression of mTOR, HIF-1α and VEGF in abdominal aorta were measured by Western blot method. RESULTS: Compared with those in the normal group, the levels of TC, TG and LDL-C increased (P<0.01) and HDL-C decreased (P<0.01) in the serum of the rats in the model group, the moxibustion group and the inhibitor group after model establishment. When compared with the normal group after intervention, in the model group, the serum levels of TC, TG, LDL-C and MDA increased (P<0.01), HDL-C level, SOD activity and NO level were reduced (P<0.01); the cell structure of the abdominal arota was abnormal, the peripheral lipids deposited seriously; and the protein expression of mTOR, HIF-1α and VEGF of abdominal aorta was elevated (P<0.01, P<0.05). In comparison with the model group, the levels of TC, TG, LDL-C and MDA were reduced (P<0.01), HDL-C levels, SOD activities and NO levels elevated (P<0.01, P<0.05), as well as the protein expression of mTOR, HIF-1α and VEGF of abdominal aorta (P<0.01, P<0.05) in the moxibustion group and the inhibitor group; besides, the vascular structure was ameliorated and the lipid deposition reduced in the moxibustion group, while, the vascular structure was still abnormal and the lipid deposition declined in the inhibitor group. When compared with the inhibitor group, the serum SOD activity and NO level increased (P<0.05) and MDA decreased (P<0.05); and the protein expression of mTOR, HIF-1α and VEGF of abdominal aorta was elevated (P<0.01, P<0.05) in the moxibustion group. CONCLUSIONS: The vascular injury due to hyperlipidemia is repaired by moxibustion with wheat-grain size cone at "Zusanli" (ST 36) through ameliorating oxidative stress, which is associated potentially with the modulation of mTOR/HIF-1α/VEGF signaling pathway.

Responsive regularity of neurons in the hindlimb region of primary somatosensory cortex to different temperature thermal needle stimulation of "Zusanli"(ST36) in mice. / å°é¼ åˆçº§ä½“æ„Ÿçš®å±‚åŽè‚¢åŒºç¥žç»å ƒå¯¹"足三里"不同温度热刺激的响应规律.

OBJECTIVES: To study the regularity of central response to thermal needle stimulation of "Zusanli" (ST36) at different temperature, and to analyze the temperature difference of central responses. METHODS: Six male C57BL/6j adult mice were used in the present study. For observing activities of neurons in the hindlimb region of left primary somatosensory cortex (S1HL, A/P=0.46 mm, M/L=1.32 mm, D/V=-0.14 mm) by using a fast high-resolution miniature two-photon microscopy (FHIRM-TPM), the mice were anesthetized with 3% isoflurane (inhalation), with its head fixed in a stereotaxic apparatus, then, adeno-associated virus (AAV-hSyn-GCaMP6f-WPRE-hGHpA, for showing intracellular calcium transients in neurons transfected) was injected into the left S1HL region using a micro-syringe after scalp surgical operation. The mice's right ST36 were stimulated using internal thermal needles with the temperature being 43 ℃, or 45 ℃, or 47 ℃, separately. Image J software and MATLAB 2020b software were used to process the image data of neuronal calcium activity (Ca2+ signaling) in the left S1HL region, including the instant maximum calcium peak value (ΔF/F) in 2 s, instant calcium spike frequency in 2 s, short-term calcium peak value (ΔF/F) in 3.5 min, short-term calcium spike frequency in 3.5 min, calcium peak duration in 3.5 min, maximum calcium peak value (ΔF/F) at the 1st , 2nd and 3rd min, and calcium spike frequency at the 1st, 2nd and 3rd min after thermal needle stimulation. RESULTS: In comparison with the normal temperature needle stimulation, the instant intracellular maximum calcium peak value, instant calcium spike frequency, short-term maximum calcium peak value, short-term calcium spike frequency, and calcium peak duration of S1HL neurons in response to 43 ℃, 45 ℃ and 47 ℃ internal thermal needle stimulation of ST36 were significantly increased (P<0.001, P<0.01). Comparison among the 43 ℃, 45 ℃ and 47 ℃ thermal needle stimulation showed that the 45 ℃ thermal needle stimulation was obviously superior to 43 ℃ and 47 ℃ thermal needle stimulation in increasing instant calcium spike frequency, short-term calcium spike frequency and calcium peak duration of S1HL neurons (P<0.001, P<0.01). The 47 ℃ thermal needle stimulation was stronger than 43 ℃ and 45 ℃ thermal needle stimulation in increasing the instant maximum calcium peak value (P<0.001). The maximum calcium peak value was apparently higher (P<0.001) at the 2nd min than that at the 1st and 3rd min after 43 ℃, 45 ℃ and 47 ℃ thermal needle stimulation. No significant differences were found in the short-term maximum calcium peak value among the 3 thermal needle stimulation and in the calcium spike frequency among the 3 time points after 43 ℃, 45 ℃ and 47 ℃ thermal needle stimulation. CONCLUSIONS: S1HL neurons respond to all 43 ℃, 45 ℃ and 47 ℃ thermal needle stimulation of ST36 in mice, while more actively to 45 ℃ thermal needle stimulation.

Moxibustion for declined cardiorespiratory fitness of apparently healthy older adults: A study protocol for a randomized controlled trial.

BACKGROUND: Aging and age-related declines lead to varying degrees of decreased cardiorespiratory fitness (CRF) in apparently healthy older adults. Exercise training, the primary approach for enhancing CRF, encounters several constraints when used with elderly individuals. Existing evidence implies that moxibustion might enhance the CRF of older adults. However, clinical research in this area still needs to be improved. METHODS: This study will employ a randomized, assessor-blinded, controlled trial design involving 126 eligible participants. These participants will be stratified and randomly assigned to one moxibustion group, one sham moxibustion group, and one blank control group. Acupoints of bilateral Zusanli (ST36), Shenque (CV8), and Guanyuan (CV4) are selected for both real and sham moxibustion groups. The treatment will last 60 min per session, 5 sessions a week for 12 weeks. The blank control group will not receive any intervention for CRF improvement. Primary outcomes will be the mean change in peak oxygen uptake (VO2peak), anaerobic threshold (AT), and serum central carbon metabolites (CCB) from the baseline to observation points. Secondary outcome measures involve the six-minute walk distance (6MWD), the Short Form 36 Health Survey (SF-36), and the Qi and Blood Status Questionnaire (QBSQ). Outcome assessments will be conducted at weeks 4, 8, 12, and 24 as part of the follow-up. Adverse events will be assessed at each visit. DISCUSSION: This trial can potentially ascertain moxibustion's effectiveness and safety in enhancing CRF among apparently healthy older adults. TRAIL REGISTRATION: ChiCTR, ChiCTR2300070303.

The treatment was given once a day, 5 days a week for 4 weeks totally in the two groups. Before and after treatment, the scores of Fugl-Meyer assessment (FMA), modified Ashworth scale (MAS) and modified Barthel index (MBI) were observed in the two groups. RESULTS: After treatment, the FMA and MBI scores were increased compared with those before treatment in the two groups (P<0.001), and the FMA and MBI scores in the observation group were higher than those in the control group (P<0.05). After treatment, the MAS scores of upper and lower limbs in the observation group were decreased compared with those before treatment (P<0.01, P<0.001), the MAS score of lower limb in the control group was decreased compared with that before treatment (P<0.05). CONCLUSIONS: MEP-oriented scalp acupuncture combined with TMS can effectively improve the limb motor ability, daily living ability and limb spasticity in patients with ischemic stroke hemiplegia.

Understanding acupuncture anesthesia from a foreign perspective： reviewing Acupuncture Anesthesia in the People's Republic of China. / 异域视角下对针刺麻醉的理解：以《针刺麻醉在中国》为例.

"Acupuncture Anesthesia in the People's Republic of China： A Trip Report of the American Acupuncture Anesthesia Study Group" (Report for short) is the first extraterritorial systematic investigation and evaluation report in the history of acupuncture anesthesia in China. After Report was released to the public, it has not drawn much attention in China. At the moment when acupuncture anesthesia is extended to perioperative treatment, by reviewing the Report, the differences in understanding acupuncture anesthesia were analyzed from a foreign perspective. Report involves the clinical observation of surgery under acupuncture anesthesia, the analysis on the factors of acupuncture anesthesia in therapeutic effects and the relevant mechanisms, and the differences in the research methods and foci on the recognition of acupuncture anesthesia between China and foreign countries. In association with the development of acupuncture anesthesia during the past 65 years and the conclusion in Report, the paper briefly describes the development and perfection of acupuncture anesthesia, the historical verification to the conclusions in Report and the limitations in modern acupuncture anesthesia. It provides some inspiration for the development of acupuncture anesthesia, acupuncture-moxibustion medicine and life science in the future.

Effects of zhongfeng cutong moxibustion on motor function and corticospinal tract in the patients with motor dysfunction during the recovery period of cerebral infarction. / ä¸­é£Žä¿ƒé€šç¸å¯¹è„‘æ¢—æ­»æ¢å¤æœŸè¿åŠ¨åŠŸèƒ½éšœç¢æ‚£è€ è¿åŠ¨åŠŸèƒ½åŠçš®è´¨è„Šé«“æŸçš„å½±å“.

OBJECTIVES: To observe the effects of zhongfeng cutong moxibustion (moxibustion therapy for unblocking and treating stroke) on the motor function and the structure of corticospinal tract (CST) in the patients with motor dysfunction during the recovery period of cerebral infarction, and to explore the central mechanism of this moxibustion therapy for improving the motor function. METHODS: Fifty patients with motor dysfunction during the recovery period of cerebral infarction were randomly divided into an observation group (25 cases, 1 case dropped out) and a control group (25 cases, 1 case dropped out). The patients in both groups underwent the conventional basic treatment. In the control group, acupuncture was applied to Baihui (GV 20) and Shuigou (GV 26), as well as Chize (LU 5), Neiguan (PC 6), Weizhong (BL 40) and Sanyinjiao (SP 6) etc. on the affected side. Besides the intervention of the control group, in the observation group, zhongfeng cutong moxibustion therapy was combined at Baihui (GV 20), Shenque (CV 8) and bilateral Zusanli (ST 36). Both acupuncture and moxibustion therapies were delivered once daily, 5 times a week, for 2 weeks. The scores of Fugl-Meyer assessment scale (FMA) and National Institutes of Health stroke scale (NIHSS) were compared between the two groups before and after treatment. The diffusion tensor imaging technique was used to observe the fractional anisotropy (FA) of CST at the bilateral whole segment, the cerebral cortex, the posterior limb of the internal capsule and the cerebral peduncle before and after treatment in the two groups. RESULTS: The scores of the upper and the lower limbs of FMA, as well as the total FMA score swere increased after treatment when compared with those before treatment in the two groups (P<0.05), the upper limb FMA score and the total FMA score in the observation group were higher than those in the control group (P<0.05), and NIHSS scores of the two groups were dropped compared with those before treatment (P<0.01). FA of CST at the bilateral sides of the posterior limb of the internal capsule and the whole segment on the focal side was improved in comparison with that before treatment in the observation group (P<0.05), and FA of CST at the healthy side of the whole segment was higher than that before treatment in the control group (P<0.05). CONCLUSIONS: Zhongfeng cutong moxibustion improves motor function and reduces neurological deficits in the patients with motor dysfunction during the recovery period of cerebral infarction, which may be related to enhancing the remodeling of white matter fiber bundles in the corticospinal tract on the focal side of the whole segment and the bilateral posterior limb of the internal capsule.

[ZHANG Jian-bin's clinical experience in treatment of depressive disorder based on the theory of governor vessel].

Depressive disorder is manifested as emotional and physical abnormality. Theoretically, the governor vessel is distributed along the spine, related to the brain and communicated with five zang and six fu organs. It is the key meridian for understanding the various symptoms of depressive disorder. Depressive disorder is caused by dysfunction, stagnation or emptiness of the governor vessel, resulting in malnutrition of the brain. In clinical diagnosis and treatment, based on the theory of the governor vessel, the etiology and pathogenesis are analyzed in the patients with depressive disorder. In order to achieve harmonizing mutually the mental and physical conditions, acupuncture is delivered to adjust the spirit and physical state, moving cupping is to regulate the governor vessel, tuina manipulation is to promote meridians and collaterals and physical exercise is to coordinate the body and the spirit.

Integrative Omic Analysis Reveals the Dynamic Change in Phenylpropanoid Metabolism in Morus alba under Different Stress.

Morus alba is used as a traditional Chinese medicine due to its various biological activities. Phenylpropanoid metabolism is one of the most important pathways in Morus alba to produce secondary metabolites and response to stress. From the general phenylpropanoid pathway, there are two metabolic branches in M. alba, including flavonoid and lignin biosynthesis, which also play roles in response to stress. However, the dynamic changes between flavonoid and lignin biosynthesis under Botrytis cinerea infection and UV-B stress in M. alba were unclear. To explore the different regulation mode of flavonoid and lignin biosynthesis in M. alba leaves' response to biotic and abiotic stress, a combined proteomic and metabolomic study of M. alba leaves under UV-B stress and B. cinerea infection was performed. The results showed that most of the proteins involved in the lignin and flavonoid biosynthesis pathway were increased under either UV-B stress or B. cinerea infection in M. alba. This was also confirmed by enzyme assays and metabolomics analysis. Additionally, the abundance of proteins involved in the biosynthesis of jasmonic acid was increased after B. cinerea infection. This suggests that both flavonoid and lignin biosynthesis participate in the responses to abiotic and biotic stress in M. alba, but they might be regulated by different hormone signaling.

[Effect of mild moxibustion at 45 ℃ with different durations at "Zusanli" （ST36） on the inflammatory factors in the abdominal aorta of hyperlipidemia rats].

OBJECTIVE: To investigate the effects of mild moxibustion at 45°C on the chronic inflammatory response of the abdominal aorta in rats with hyperlipidemia and the effects of different moxibustion durations. METHODS: Thirty-six SD rats were randomly divided into the following groups： blank control group (2 weeks), model group (2 weeks), moxibustion group (2 weeks), blank group (4 weeks), model group (4 weeks), and moxibustion group (4 weeks). A model of hyperlipidemia with chronic inflammation was established through high-fat diet feeding for 8 weeks. Rats in the moxibustion groups received mild moxibustion treatment at bilateral "Zusanli"(ST36) at 45 °C, 10 min every time, once a day, for consecutive 2 or 4 weeks. The morphology of the abdominal aorta in each group was observed by using HE staining. Contents of serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), oxidized low-density lipoprotein (ox-LDL), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), endothelin-1 (ET-1) and the contents of nitric oxide (NO), ox-LDL, and ET-1 in the abdominal aorta were measured by using ELISA. Protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta of rats in each group were detected by using Western blot and real-time fluorescence quantitative PCR respectively. The positive expression of IL-6 in the abdominal aorta of rats was detected by Immunofluorescence. RESULTS: Compared to the blank control group, rats in the model group had increased contents of LDL, TC, TG, ox-LDL, VCAM-1, ICAM-1, IL-6, TNF-α, and ET-1 in the serum, increased contents of ox-LDL and ET-1 in the abdominal aorta, increased protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta(P<0.01, P<0.05, P<0.001), with decreased HDL content in the serum, decreased NO content in the abdominal aorta (P<0.01, P<0.05), as well as dark pink abdominal aorta, rough textures in the adventitia, media, and intima, and rough endothelial layer. Compared to the model group(2 weeks), LDL, ICAM-1, ET-1 contents in the serum, ox-LDL content in the abdominal aorta were decreased(P<0.05), while serum IL-6 and TNF-α contents, and NO content in the abdominal aorta were significantly increased(P<0.01, P<0.05), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(2 weeks). Compared to the model group(4 weeks), contents of LDL, TC, TG, VCAM-1, ICAM-1, IL-6, TNF-α, ox-LDL, and ET-1 in the serum, ox-LDL and ET-1 contents in abdominal aorta, protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta were significantly decreased(P<0.05, P<0.01), while HDL content in the serum and NO content in the abdominal aorta were significantly increased(P<0.05, P<0.01), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks). In addition, content of HDL in the serum were significantly increased(P<0.05), while TNF-α content in the serum, protein expression of IL-6 in the abdominal aorta were significantly decreased (P<0.001, P<0.05), with smoother vascular walls, and clearer nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks), in comparison with the moxibustion group(2 weeks). CONCLUSION: Mild moxibustion of 45 °C at ST36 can improve vascular endothelial damage and inflammatory response induced by high-fat diet by regulating serum lipids, vascular tone, adhesion molecules, and inflammatory factors, of which the effect of moxibustion intervention for 4 weeks is more significant.

Positive effects of selenized-oligochitosan on zearalenone-induced intestinal dysfunction in piglets.

This paper assessed the positive effects of selenized-oligochitosan (SOC) on zearalenone(ZEN)-induced intestinal dysfunction in piglets. Sixty piglets were randomly divided into 4 groups. Group C was fed the basal diet as a control and Group Z was supplemented with 2 µg/g ZEN in the basal diet; Group ZS1 and ZS2 were supplemented with 0.3 or 0.5 µg/g SOC (calculated by selenium), in addition to 2 µg/g ZEN in the basal diet. After 42 days, ileal mucosal structure, digestive enzyme activities, tight junction protein mRNA expressions, plasma D-lactate and D-xylose contents, and plasma diamine oxidase activities were determined. Compare with Group C, ileal villus height, value of villus height/crypt depth, trypsin, lipase and α-amylase activities, occluding, claudin-1 and ZO-1 mRNA expressions, and plasma D-xylose levels were significantly decreased (p < 0.01) in piglets of group Z; while compare to Group C, ileal crypt depth, plasma D-lactate contents and diamine oxidase activities were significantly increased in piglets of group Z (p < 0.01 or p < 0.05). Compare with Group Z, ileal villus height, lipase and α-amylase activities, occluding, claudin-1 and ZO-1 mRNA expressions, and plasma D-xylose levels were significantly elevated in piglets of group ZS1 and ZS2 (p < 0.01); while compare to Group Z, plasma D-lactate and diamine oxidase contents were significantly reduced in piglets of group ZS1 and ZS2 (p < 0.01 or p < 0.05). Compare with Group Z, value of villus height/crypt depth and trypsin activity were significantly promoted in piglets of group ZS2 (p < 0.01); whereas ileal crypt depth was significantly reduced in piglets of group ZS2 (p <0.01).Thus, SOC can mitigate ZEN-induced intestinal dysfunction in piglets.

Acupuncture for gait disturbance of patients with subacute and chronic stroke: a systematic review and meta-analysis protocol.

INTRODUCTION: Hemiparetic gait is one of the most common sequelae of a stroke. Acupuncture has shown potential in correcting hemiplegic gait patterns and improving motor function recovery after stroke. However, controversial findings and a lack of supportive evidence on the effectiveness of acupuncture for post-stroke hemiplegia. The intelligent gait analysis system provides a new perspective for the study of hemiparetic gait. This systematic review aims to collect relevant studies and critically evaluate the efficacy and safety of acupuncture in alleviating gait disturbance of post-stroke hemiplegia based on quantified gait parameters. METHODS AND ANALYSIS: A comprehensive search of PubMed, Embase, Cochrane stroke group trials register, Cochrane Central Register of Controlled Trials, CINAHL, AMED, three Chinese databases (Chinese Biomedical Literatures database (CBM), National Knowledge Infrastructure (CNKI), and Wan fang Digital Periodicals), four trails registries (The WHO International Clinical Trials Registry Platform, The Chinese Clinical Trial Registry, The US National Institutes of Health Ongoing Trials Register, and The Australian New Zealand Clinical Trials Registry) will be conducted to identify randomised controlled trials of acupuncture for gait disturbance in post-stroke patients. No restrictions on language or publication status. The primary outcomes are gait temporospatial parameters (eg, step length, stride length, step width, step frequency (cadence), walking speed, etc), and gait kinematic parameters (eg, hip peak flex/extend angle, knee peak flex/extend angle, ankle peak dorsi/plantar-flexion angle, etc). We will assess bias using the approach recommended by the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis will be conducted to synthesise the evidence for each outcome measure. The χ2 test and I2 statistic will be used for assessing heterogeneity between studies. ETHICS AND DISSEMINATION: No ethical approval is needed because no primary data is collected. Scientific conferences or peer-reviewed journals will publish the findings.

[Moxibustion of 45 ℃ at "Zusanli" (ST36) improves vascular endothelial oxidative stress in hyperlipidemia rats].

OBJECTIVE: To explore the antioxidant effect of moxibustion on vascular endothelial function and the under-lying mechanism. METHODS: Forty male SD rats were randomly divided into blank, model, moxibustion and endothelial nitric oxide synthase (eNOS) inhibitor groups, with 10 rats in each group. Hyperlipidemia rat model was established by high fat diet for 8 weeks. Rats in the moxibustion group received 45 ℃ moxibustion at "Zusanli" (ST36) for 10 min once daily for consecutive 4 weeks. Rats in the eNOS inhibitor group received intraperitoneal injection of eNOS inhibitor L-NAME (1 mg/100 g) at the same time of moxibustion intervention. The morphology of abdominal aorta endothelium was observed by HE staining. Lipid deposition in abdominal aorta was observed by oil red O staining.

The expression of eNOS in abdominal aorta was detected by immunofluorescence. RESULTS: HE staining of the abdominal aorta showed no significant pathological abnormality in the blank group; the endovascular cortex was rough, and the inner, media and outer membrane were rough in the model group; the nucleus and surrounding tissue structure were clear and the vascular wall was smooth in the moxibustion group; abdominal aorta texture was rough in the eNOS inhibitor group. Compared with the blank group, the area of oil red O staining in abdominal aorta increased (P<0.05); the contents of serum TC, TG and LDL-C increased (P<0.01, P<0.05) while HDL-C decreased (P<0.05); the contents of ET-1 in serum and abdominal aorta were increased (P<0.01, P<0.05) while the contents of NO and eNOS were decreased (P<0.05, P<0.001); the contents of ROS, ox-LDL and MDA in serum and abdominal aorta were increased (P<0.001, P<0.01, P<0.000 1) while the content of SOD in abdominal aorta was decreased (P<0.000 1); the expression level of eNOS in abdominal aorta was decreased (P<0.05) in the model group. Compared with the model group, the area of oil red O staining in abdominal aorta decreased (P<0.05); the contents of TC, TG and LDL-C in serum decreased (P<0.05) while HDL-C increased (P<0.05); the contents of ET-1 in serum and abdominal aorta were decreased (P<0.01, P<0.05) while the contents of NO and eNOS in abdominal aorta were increased (P<0.001, P<0.01); the contents of ROS and MDA in serum and abdominal aorta were decreased (P<0.001, P<0.01, P<0.05), the content of ox-LDL was decreased (P<0.01) and the content of SOD was increased (P<0.000 1) in abdominal aorta; the expression level of eNOS in abdominal aorta was increased (P<0.05) in the moxibustion group. Compared with the moxibustion group, the contents of serum TC, LDL-C and MDA in the eNOS inhibitor group were increased (P<0.05); the contents of ET-1, ROS, ox-LDL and MDA in abdominal aorta were increased (P<0.05), the contents of NO, eNOS and SOD were decreased (P<0.05); the expression level of eNOS in abdominal aorta was decreased (P<0.05). CONCLUSION: 45 ℃ moxibustion at ST36 can protect and repair vascular endothelial injury in abdominal aorta of hyperlipidemia rats and improve the oxidative stress of vascular endothelium.

Grain-sized moxibustion at Zusanli (ST36) promotes hepatic autophagy in rats with hyperlipidemia by regulating the ULK1 and TFEB expression through the AMPK/mTOR signaling pathway.

Objective: Grain-sized moxibustion is an effective treatment for hyperlipidemia, but how it regulates dyslipidemia and liver lipid deposits still needs to be fully understood. This study explored the molecular biological mechanism of grain-sized moxibustion to regulate hepatic autophagy in hyperlipidemic rats by affecting ULK1 and TFEB through the AMPK/mTOR signaling pathway. Methods: Thirty male Sprague-Dawley (SD) rats were fed a high-fat diet for eight weeks to induce hyperlipidemia. Hyperlipidemic rats were divided into the HFD group, HFD + Statin group, HFD + CC + Moxi group, and grain-sized moxibustion intervention group (HFD + Moxi group). The control (Blank) group consisted of normal rats without any intervention. Grain-sized moxibustion and drug interventions were initiated eight weeks after high-fat diet induction and continued for ten weeks. Serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), as well as hepatic triglyceride (TG), were measured after treatment. Hepatic steatosis and the expression of LC3I, LC3II, p62, p-AMPK, AMPK, p-mTOR, mTOR, ULK1, p-ULK1, and TFEB in the liver were analyzed. Results: Compared with the HFD group, grain-sized moxibustion improved hyperlipidemia and hepatocyte steatosis, increased the LC3, p-AMPK, p-ULK1, and nuclear TFEB expression in the liver, but decreased the p62 and p-mTOR expression. Conclusion: Grain-sized moxibustion at ST36 acupoints could regulate the blood lipid level of SD rats with hyperlipidemia, increase the expression level of ULK1 and TFEB by activating the AMPK/mTOR signaling pathway in liver tissues, and initiate the transcription of autophagy genes such as LC3.

Mechanism of Acupuncture and Moxibustion on Promoting Mucosal Healing in Ulcerative Colitis.

The latest guideline about ulcerative colitis (UC) clinical practice stresses that mucosal healing, rather than anti-inflammation, is the main target in UC clinical management. Current mucosal dysfunction mainly closely relates to the endoscopic intestinal wall (mechanical barrier) injury with the imbalance between intestinal epithelial cells (IECs) regeneration and death, as well as tight junction (TJ) dysfunction. It is suggested that biological barrier (gut microbiota), chemical barrier (mucus protein layer, MUC) and immune barrier (immune cells) all take part in the imbalance, leading to mechanical barrier injury. Lots of experimental studies reported that acupuncture and moxibustion on UC recovery by adjusting the gut microbiota, MUC and immune cells on multiple targets and pathways, which contributes to the balance of IEC regeneration and death, as well as TJ structure recovery in animals. Moreover, the validity and superiority of acupuncture and moxibustion were also demonstrated in clinic. This study aims to review the achievements of acupuncture and moxibustion on mucosal healing and analyse the underlying mechanisms.

[Professor ZHANG Jian-bin's clinical experience in "moving cupping therapy on the back"].

This paper summarizes Professor ZHANG Jian-bin's experience in "moving cupping therapy on the back" in clinical practice. Professor ZHANG Jian-bin is good at applying the theory of governor vessel to the clinical diagnosis and treatment. He believes that the moving cupping therapy is the supplementation of "spinal therapy" in clinical diagnosis and treatment. He emphasizes that during the moving cupping therapy exerted, the physicians should observe carefully to in-time obtain the perceived feedback of treatment in patients. Afterward, the cupping marks left should be inspected to discover the location of disorder in the body, thus, a targeted treatment can be provided. Besides, the prognosis of the disease can be judged by the feedback after many treatments with the moving cupping therapy. The moving cupping therapy displays its important value in the diagnosis and treatment of disease, as well as the evaluation of the prognosis.

[Progress of researches on involvement of corticospinal tract in the effect of acupuncture on improvement of post-stroke motor dysfunction].

The corticospinal tract (CST), descending from the frontoparietal cortex and traveling down to terminate at the anterior horn of the spinal cord to mediate voluntary movements, is frequently injured from the infarcted or hemorrhagic cerebrovascular insults due to stroke. Under the circumstances, motor dysfunction seriously affects the patient's quality of life. Acupuncture therapy has a sequelae, especially in improving motor deficits. In the present paper, we reviewed the current development of researches on acupuncture treatment of poststroke motor dysfunction and its biological mechanisms from 1) delaying patients' development of neuronal degeneration and white matter fibrosis (Wallerian degeneration), 2) improving patients' upper limb motor function and daily life ability by promoting the repair of white matter tracts and CST on the affected side, 3) promoting the compensation of CST on the healthy side, 4) reconstructing the motor conduction pathway to strengthen the bilateral brain connection in ex-perimental animals, and 5) strengthening the sprouting of the contralateral CST to dominate the affected side again across the midline. In addition, acupuncture stimulation induced improvement of axonal rewiring for corticospinal innervation is also possibly related to its functions in accelerating the synthesis and release of neurotrophic factors, down-regulating Nogo-A/RhoA signaling and activating vascular epithelial growth factor/Dll4/Notch signaling pathways.

A Quassinoid Diterpenoid Eurycomanone from Eurycoma longifolia Jack Exerts Anti-Cancer Effect through Autophagy Inhibition.

Eurycomanone (EN) is one of the representative quassinoid diterpenoids from roots of Eurycoma longifolia Jack, a natural medicine that is widely distributed in Southeast Asia. Previous studies showed that EN induces cancer cell apoptosis and exhibits anti-cancer activity, but the molecular mechanism of EN against cancer has still not been elucidated. In this study, we examined the regulatory effect of EN on autophagy to reveal the mechanism of EN-mediated colon cancer growth inhibition. First, we found that EN is able to inhibit colon cancer cell proliferation and colony formation. The angiogenesis level in cancer cells was inhibited as well. Next, the treatment of EN led to the suppression of autophagy, which was characterized by the downregulation of the LC3-II level and the formation of GFP-LC3 puncta under EN treatment in colon cancer. Moreover, we revealed that the mTOR signaling pathway was activated by EN in a time- and concentration-dependent manner. Finally, autophagy induction protected colon cancer cells from EN treatment, suggesting that autophagy improves cell survival. Taken together, our findings revealed the mechanism of EN against colon cancer through inhibiting autophagy and angiogenesis in colon cancer, supporting that the autophagy inhibitor EN could be developed to be a novel anti-cancer agent.

The involvement of Parkin-dependent mitophagy in the anti-cancer activity of Ginsenoside.

Colon cancer, the third most frequent occurred cancer, has high mortality and extremely poor prognosis. Ginsenoside, the active components of traditional Chinese herbal medicine Panax ginseng, exerts antitumor effect in various cancers, including colon cancer. However, the detailed molecular mechanism of Ginsenoside in the tumor suppression have not been fully elucidated. Here, we chose the representative ginsenoside Rg3 and reported for the first time that Rg3 induces mitophagy in human colon cancer cells, which is responsible for its anticancer effect. Rg3 treatment leads to mitochondria damage and the formation of mitophagosome; when autophagy is inhibited, the clearance of damaged mitochondria can be reversed. Next, our results showed that Rg3 treatment activates the PINK1-Parkin signaling pathway and recruits Parkin and ubiquitin proteins to mitochondria to induce mitophagy. GO analysis of Parkin targets showed that Parkin interacts with a large number of mitochondrial proteins and regulates the molecular function of mitochondria. The cellular energy metabolism enzyme GAPDH is validated as a novel substrate of Parkin, which is ubiquitinated by Parkin. Moreover, GAPDH participates in the Rg3-induced mitophagy and regulates the translocation of Parkin to mitochondria. Functionally, Rg3 exerts the inhibitory effect through regulating the nonglycolytic activity of GAPDH, which could be associated with the cellular oxidative stress. Thus, our results revealed GAPDH ubiquitination by Parkin as a crucial mechanism for mitophagy induction that contributes to the tumor-suppressive function of ginsenoside, which could be a novel treatment strategy for colon cancer.

Quantitative chemical proteomics reveals anti-cancer targets of Celastrol in HCT116 human colon cancer cells.

BACKGROUND: Celastrol (Cel) is a naturally-derived compound with anti-cancer properties and exerts beneficial effects against various diseases. Although an extensive body of research already exists for Cel, the vast majority are inductive studies with limited validation of specific pathways and functions. The cellular targets that bind to Cel remain poorly characterized, which limits attempts to uncover its mechanism of action. PURPOSE: The present study aims to comprehensively identify the protein targets of Cel in HCT116 cells in an unbiased manner, and elucidate the mechanism of the anti-cancer activity of Cel based on target information. METHODS: A comprehensive analysis of protein targets that bind to Cel was performed in HCT116 colon cancer cells using a quantitative chemical biology method. A Cel probe (Cel-P) was synthesized to allow in situ monitoring of treatment in living HCT116 cells, and specific targets were identified with a quantitative chemical biology method (isobaric tags for relative and absolute quantitation) using mass spectrometry. RESULTS: In total, 100 protein targets were identified as specific targets of Cel. Pathways associated with the targets were investigated. Multiple pathways were demonstrated to be potential effectors of Cel. These pathways included the suppression of protein synthesis, deregulation of cellular reactive oxygen species, and suppression of fatty acid metabolism, and they were validated with in vitro experiments. CONCLUSION: The extensive information on the protein targets of Cel and their functions uncovered by this study will enhance the current understanding of the mechanism of action of Cel and serve as a valuable knowledge base for future studies.
