Objective: To observe the effect of acupuncture of "Tianshu"(ST25) at different depths on colonic transportation function, expressions of colonic substance P (SP) and interstitial cells of Cajal (ICC) in rats with slow transit constipation (STC), so as to explore its mechanisms underlying improvement of STC．.
Methods: Fifty male Wistar rats were selected and randomly divided into control，STC model，conventional acupuncture，deep needling group 1 and deep needling group 2 groups，with 10 rats in each group．The STC model was established by gavage of 1 mg/mL compound diphenoxylate suspension (10 mg/kg), once every other day for 21 days, and rats of the control group were given the same dose of distilled water by gavage．EA (2 Hz, 2 mA) was applied to "Tianshu"(ST25), with the acupuncture needle inserted to a depth of 3 mm for rats of the conventional acupuncture group, 4.5 mm for those of deep needling group 1, and 10 mm for those of the deep needling group 2. The acupuncture needle was twirled for 1 min, then retained for 15 min each time, once a day for 15 consecutive days．Following modeling, rats of the 4 groups and the control group received gavage of active carbon 2 mL (100 g/L) for observing the excretion time of the first black stool grain to assess the intestinal transit function. The colonic myoelectric activities (frequency and amplitude) were recorded by using BIOPAC multichannel physiograph. The immunoactivity of SP and c-kit (a transmembrane protein kinase for identification of ICC) of colonic musculature was detected by immunohistochemistry.
Results: Compared with the control group，the time of excretion of the first black stool grain, and the amplitude of colonic electromyogram (EMG) were significantly increased (P<0.01), while the frequency of EMG, expressions of SP and c-kit (ICC) were significantly decreased in the model group (P<0.01). In contrast to the model group, both deep needling group 1 and 2 had a decrease in the time of excretion of the first black stool grain, and amplitude of intestinal EMG, and an increase of frequency of intestinal EMG, and immunoactivity of SP and c-kit (P<0.01). The effect of deep needling 2 is superior to that of deep needling 1 in reducing the time of excretion of the first black stool grain (P<0.05), lowering the amplitude of EMG of the gut smooth muscle (P<0.05) and in increasing the frequency of EMG (P<0.05) and the expressions of SP and c-kit (P<0.05). No significant changes were found in the levels of frequency and amplitude of EMG, and expressions of SP and c-kit after routine needling in comparison with the model group (P>0.05), except the excretion time of the first black stool grain (P<0.05).
Conclusion: Deep needling at ST25 at depth of 4.5 mm and 10 mm，especially at depth of 10 mm，has a significant effect in promoting gut motility to ameliora

Objective: To analyze the current status of animal experiments of acupuncture in intervening chronic fatigue syndrome, so as to search formethods to improve the quality of animal experiment reports.
Methods: From the databases, such as CNKI, VIP, Wanfang, SinoMed, PubMed, Web of Science, Embase and Cochrane Library, the literature of animal experiment on acupuncture treatment for chronic fatigue syndrome was searched from January 1st, 2011 to April 2nd, 2022. Data were extracted according to the animal research reporting in vivo experiment (ARRIVE) guidelines 2.0 and gold standard publication checklist (GSPC), and statistical analysis was performed using Excel 2019.
Results: A total of 16 studies were finally included. The satis-faction rate of essential items in the ARRIVE guidelines 2.0 is 41.76%，while the satisfaction rate of recommended items is only 27.73% and of the GSPC is 25.89%. Out of 16 studies, 13 of them explained the reasons for animal exclusion in the experiment, 8 provided specific randomized methods, 8 described detailed information on animal species, strains, and quantities, 3 basically indicated that they had passed ethical review, 7 explained the limitations of the research. All 16 studies reported the main findings and elucidated their potential clinical or scientific value.
Conclusion: Current animal studies on acupuncture in intervening the chronic fatigue syndrome are of certain limitation. Descriptions of multiple items are incomplete or missing, which prevents rea-ders from assessing reliability and authenticity of the animal experiment. It is recommended that in future research, experimental design, execution and report should be carried out according to the report guidelines for animal experiment to improve research quality.
目的：分析针灸干预慢性疲劳综合征动物实验的现状，探讨提高动物实验报告质量的方法。方法：检索2011年1月1日至2022年4月2日针灸治疗慢性疲劳综合征动物实验文献，检索CNKI、VIP、万方、SinoMed、PubMed、Web of Science、Embase和Cochrane Library等数据库。根据动物研究报告体内实验（ARRIVE）指南2.0和金标准出版物检查表（GSPC）提取数据，并使用Excel 2019进行统计分析。结果：最终纳入16项研究。ARRIVE指南2.0中基本项目的满意度为41.76%，而推荐项目的满意度仅为27.73%，GSPC的满意度为25.89%。在16项研究中，13项解释了实验中排除动物的原因，8项提供了具体的随机方法，8项描述了动物物种、品系和数量的详细信息，3基本上表明他们已经通过了伦理审查，7解释了研究的局限性。所有16项研究都报告了主要发现，并阐明了其潜在的临床或科学价值。结论：目前针灸干预慢性疲劳综合征的动物研究具有一定的局限性。多个项目的描述不完整或缺失，这使研究人员无法评估动物实验的可靠性和真实性。建议在未来的研究中，应按照动物实验报告指南进行实验设计、执行和报告，以提高研究质量。

Objective: To observe the meridian-acupoint reactions of foot three yin meridians in primary dysmenorrhea(PD) and secondary dysmenorrhea(SD) patients, so as to summarize the rules of meridian-acupoint reaction and acupoints selection.
Methods: Thirty-five patients with PD (PD group), 34 patients with SD (SD group) and 35 healthy subjects (healthy group) were recruited. The compression method was used to examine the lower leg segment of the foot three yin meridians. Positive reactions(palpable skin changes, including cords, nodules, depressions) and tenderness of meridians and acupoints were recorded. The visual analogue scale (VAS) was used to evaluate the tenderness severity of acupoints.
Results: Compared with the healthy group, the probability of positive reactions and tenderness in foot three yin meridians were higher in PD and SD groups (P<0.01,P<0.05). Compared with the PD group, the probability of positive reactions in Spleen and Liver Meridians were higher in the SD group, with higher probability of tenderness in Liver Meridian(P<0.05). The probability of positive reactions and tenderness in the Spleen Meridian of PD and SD groups was significantly higher than that in the Kidney Meridian (P<0.01), while the probability of tenderness in the Spleen Meridian of the PD group was significantly higher than that in the Liver Meridian (P<0.05). Positive reactions and tenderness were concentrated at Yinlingquan (SP9), Diji (SP8) and Sanyinjiao (SP6) of Spleen Meridian and Xiguan (LR7) and Ligou (LR5) in Liver Meridian of PD and SD groups. In comparison with the PD group, the probability of positive reactions, tenderness and VAS score of SP8 and LR5 of the SD group were higher (P<0.05, P<0.01).
Conclusion: The positive reaction occurs most frequently in the Spleen Meridian, followed by the Liver Meridian, and least frequently in the Kidney Meridian. The acupoints with positive reaction are different between PD and SD, which suggests that the Spleen Meridian acupoints should be the main acupoints when treating the two kinds of dysmenorrhea, and acupoints should also be selected according to the meridian and acupoint examination results.

Objective: To observe the effect of heat-tonifying needling on Keap1-Nrf2/ARE/HO-1 signal transduction pathway in knee synovium in rabbits with cold syndrome type rheumatoid arthritis (RA), so as to explore its mechanisms underl-ying improvement of RA.
Methods: New Zealand rabbits were randomly divided into normal control, RA model, uniform reinforcing-reducing acupuncture, twisting reinforcing acupuncture and heat-tonifying acupuncture groups, with 6 rabbits in each group. The cold syndrome type RA model was established by subcutaneous injection of mixture fluid of ovalbumin and Freund's complete adjuvant at the shoulder-back as well as injection of mixture of ovalbumin and normal saline into knee-joint cavity combined with ice-compress freezing. Acupuncture stimulation (uniform reinforcing-reducing, or twisting reinforcing or heat-tonifying) was applied to bilateral "Zusanli"(ST36) for 1 min with the needle retained for 30 min, once a day for 7 consecutive days. The general conditions of rabbits in each group were recorded, the thermal pain threshold (TPT) and perimeter of knee joints was measured. Conditions of the synovium in the knee cavity, hydrops, blood flow signal, articular surface, and related muscles were observed by using a color Doppler ultrasonic diagnostic apparatus, and the blood flow signals inside the synovium (image scores) were divided into 0 (no signals), I (1 or 2 dot-like signal), II (less than half) ad III (more than half). After H.E. staining, the pathological changes (0-3 points) were assessed according to the state of inflammatory cell infiltration, and hyperplasia of synovial matrix and coating cells. The expression levels of Keap1, Nrf2, HO-1 and GSH-PX1 mRNAs in the knee synovium were detected by quantitative real-time PCR, and the expression of knee synovial HO-1 protein was measured by Western blot.
Results: In comparison with the normal control group, the model group had a significant increase in the perimeter, pathological score, expression of Nrf2, HO-1 mRNAs and HO-1 protein (P<0.05), and an obvious decrease in the TPT, expression levels of Keap1 and GSH-PX1 mRNAs (P<0.05). Relevant to the model group, all the three acupuncture maneuvers reversed modeling-induced increase of perimeter and pathological score (P<0.05), decrease of TPT and expression of GSH-PX1 mRNA(P<0.05), further down-regulated expression of Keap1 mRNA (P<0.05), further up-regulated the expression of Nrf2, HO-1 mRNAs and HO-1 protein (P<0.05). The heat-reinforcing manipulation was significantly superior to uniform reinforcing-reducing and twirling reinforcing manipulations in up-regulating TPT, and expression of Nrf2 mRNA, GSH-PX1 mRNA, HO-1 mRNA and protein (P<0.05), and in down-regulating pathological score and Keap1 mRNA expression (P<0.05).

Objective: To investigate the possible mechanism of "regulating qi and relieving depression" acupuncture underlying improvement of chronic unpredictable mild stress (CUMS)-induced depression in rats by using Tandem Mass Tags(TMT) quantitative proteomics technique.
Methods: Thirty-six male SD rats were randomly divided into control, model and acupuncture groups, with 12 rats in each group. The depression model was induced by CUMS stress for 21 days. After the depression model was successfully established, the rats in the acupuncture group received manual acupuncture stimulation at "Baihui" (GV20) and "Yintang" (GV24+) for 20 min, once daily for 21 days. Open field test, sugar water preference test and forced swimming test (FST) were used to evaluate the behavioral changes. TMT quantitative proteomics was used to obtain differential proteins in the hippocampus tissue and related signaling pathways enrichment was analyzed, followed by verifying differential protein pathways by using Western blot and immunofluorescence methods.
Results: Behavior tests showed that on the 21st and 42nd days, the horizontal crossing times, walking distance and percentage of sugar water consumption were significantly decreased (P<0.05), while the immobility time of FST was obviously increased (P<0.05) in the model group relevant to the control group. After acupuncture intervention, the horizontal crossing times, walking distance and percentage of sugar water consumption were significantly increased (P<0.05), and the immobility time was apparently decreased (P<0.05) in the acupuncture group relevant to the model group. The TMT quantitative proteomics of hippocampus tissue displayed that of the 71 differential proteins (model group vs control group), 32 was down-regulated and 39 up-regulated in the model group; and among the above 71 differential proteins, there were 20 differential proteins between acupuncture group and model group, 15 down-regulated and 5 up-regulated in the acupuncture group (vs the model group). The expression of Mapk8ipl was up-regulated in the model group (vs the control group) and down-regulated in the acupuncture group (vs the model group). GO and KEGG enrichment analysis showed that these acupuncture-related differential proteins mainly involve the regulation of blood coagulation system, MAPK signaling pathway, etc. We selected the MAPK/JNK signaling pathway related to depression for verification. Western blot showed that the expression levels of c-JUN and phosphorylated c-JUN terminal kinase (p-JNK) proteins in the hippocampus were up-regulated in the model group relevant to the control group (P<0.05); while the expression levels of c-JUN and p-JNK proteins in the hippocampus were down-regulated in the acupuncture group relevant to the model group (P<0.05).

Objective: To observe the effect of moxibustion at "Zusanli"(ST36) on the silent information regulator 1 (SIRT1) /p53 signaling pathway in subacute aging model rats, so as to reveal its mechanisms in delaying aortic aging.
Methods: Male SD rats were divided into blank group, model group, prevention group and treatment group, with 20 rats in each group. Subacute aging model was established by intraperitoneal injection of D-galactose(500 mg·kg-1·d-1). In the morning, rats in the prevention group received moxibustion at ST36 with 3 moxa cones after modeling operation, once every day for 42 d. From the day after the 42-day modeling, rats in the treatment group received the same moxibustion treatment as the prevent group for 28 d. Rats in the blank and model group were fixed in the similar way as the other two groups, for 5 min. Contents of serum SIRT1, p53, endothelial nitric oxide synthase(eNOS) and vascular endothelial growth factor(VEGF) were detected by ELISA. Histopathological changes of aortic tissue were observed after HE staining. Expressions of SIRT1 and p53 mRNAs and proteins in aortic tissue were detected by qPCR and Western blot.
Results: Compared with the blank group, the model group showed aging symptoms, the prevention group was similar to the blank group, and the treatment group was slightly better than the model group. Compared with the blank group, content of serum p53, expressions of p53 mRNA and protein in aortic tissues were significantly increased (P<0.05, P<0.01), while contents of serum SIRT1, VEGF, eNOS, and expressions of SIRT1 mRNA and protein in aortic tissues were significantly decreased (P<0.05, P<0.01) in the model group. Compared with the model group, content of serum p53, and expression of p53 mRNA and protein in aortic tissues were significantly decreased (P<0.05, P<0.01) in the prevention and treatment groups, while the contents of serum SIRT1, VEGF, eNOS, and the expressions of SIRT1 mRNA and protein in aortic tissues were significantly increased (P<0.05, P<0.01). Compared with the treatment group, rats in the prevention group displayed significant improvement of the above indexes (P<0.05). Compared with the blank group, the endothelial cells were disordered, the vessel wall was significantly thickened, and the senescent cells were increased in the model group; the blood vessel walls were thinner to varying degrees, and the senescent cells were reduced and unevenly distributed in the prevention and treatment groups. The histopathological lesion was improved more obviously in the prevention group than the treatment group.
Conclusion: Moxibustion at ST36 can alleviate vascular endothelial injury and oxidative stress in subacute aging rats, which may be related to its effect in regulating the SIRT1/p53 signaling pathway.

Objective: To observe the effect of moxibustion preconditioning on learning-memory ability, Toll like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB) signal pathway related proteins and microglia in rats with Alzheimer's disease (AD), so as to explore its possible mechanisms underlying improvement of AD.
Methods: Male SD rats were randomly divided into normal, sham operation, AD model and pre-moxibustion groups, with 9 rats in each group. Moxibustion was applied to "Baihui"(GV20), "Shenshu"(BL23) and "Zusanli"(ST36) for 15 min, once daily, 6 days as a course of treatment for 3 courses. At the end of moxibustion, the AD model was established by injection of Aβ25-35 aggregation solution into the bilateral hippocampus. The sham operation group was only injected with the same amount of 0.9% Nacl solution. The spatial learning-memory ability of rats was detected by Morris water maze test, the ultrastructure of hippocampal neurons was observed by transmission electron microscope (TEM). The histopathological changes of hippocampus tissue were observed by HE staining, and the protein expression levels of TLR4 and NF-κB p65 in the hippocampus detected by Western blot, and the positive expressions of Iba-1, CD80 and CD206 in the hippocampal CA1 region were detected by immunofluorescence labeling. The contents of inflammatory factors IL-1β, TNF-α and IL-10 in the hippocampus were measured by ELISA.
Results: Compared with the sham operation group, the escape latency was significantly increased (P<0.01), and the number of platform quadrant crossing times was decreased (P<0.01) in the model group. In comparison with the model group, the increased escape latency and the decreased platform quadrant crossing times were reversed in the pre-moxibustion group (P<0.01). TEM and light microscope observation showed loose arrangement of cells, enlarged cell space, degeneration, swelling and deformation of hippocampal neurons, rupture of membranes of a large number of cells, reduction of mitochondria, dilation of endoplasmic reticulum, and matrix vacuoles, uneven distribution of organelles and cytoplasm, and being difficult in distinguishing the nuclear cytoplasm in the model group, which was relatively milder in the pre-moxibustion group. The expression levels of hippocampal NF-κB p65 and TLR4, the mean immunofluorescence density of Iba-1 and CD80, as well as the contents of IL-1β and TNF-α in hippocampal CA1 region were significantly increased in the model group than those in the sham operation group (P<0.01), and obviously decreased in the pre-moxibustion group than those in the model group (P<0.05, P<0.01). Whereas the expression of CD206 and the content of IL-10 were evidently decreased in the model group than those in the sham operation group (P<0.01), and strikingly increased in the pre-moxibustion group than those in the model group (P

Objective: To observe the effects of electroacupuncture pretreatment on postoperative cognitive dysfunction (POCD), neuronal apoptosis and neuron-inflammation in aged rats.
Methods: Thirty-six male SD rats aged 20 months were randomly divided into sham operation group, model group and electroacupuncture (EA) group, with 12 rats in each group. The POCD rats model was prepared by internal fixation of left tibial fracture. Five days before modeling, EA stimulation (2 Hz/15 Hz, 1 mA, 30 min) was applied to "Zusanli" (ST36), "Hegu" (LI4) and "Neiguan" (PC6) on the unaffected side of rats in the EA group, once a day for consecutive 5 d. The learning and memory abilities of rats were evaluated by water maze test 31-35 days after operation. The apoptosis of hippocampal neurons was observed by Tunel/NeuN double staining. The expressions of high mobility group protein B1 (HMGB1) and phosphorylated (p)-nuclear factor (NF)-κB in microglia cells in hippocampal dentate gyrus were detected by immunofluorescence staining. The expression levels of interleukin (IL)-6 and IL-1β in the hippocampus were detected by Western blot.
Results: Compared with the sham operation group, the escape latency was prolonged (P<0.05); the frequency of crossing the original platform, ratio of the swimming distance and the time in the target quadrant of the Morris water maze were significantly decreased (P<0.05); the apoptosis rate of hippocampal neurons was significantly increased (P<0.05); the expressions of HMGB1 and p-NF-κB in microglia cells in the dentate gyrus and the expression levels of IL-6 and IL-1β in hippocampus were increased (P<0.05) in the model group. Compared with the model group, the results of the above indexes were all opposite (P<0.05) in the EA group.
Conclusion: EA preconditioning can regulate hippocampal inflammatory response, alleviate neuronal apoptosis rate and long-term cognitive dysfunction in aged rats with POCD, the mechanisms may be related to the inhibition of microglia HMGB1/NF-κB pathway in hippocampal dentate gyrus.

The nervous system is the necessary condition for inducing the curative effect of acupuncture. Both the sympathetic and vagal nerve systems are widely distributed throughout the body and organically connect various systems and organs of the human body. In maintaining the coordination and unity of human physiological activities, it is in line with the holistic view and bidirectional regulation of acupuncture, and fits in with the meridian theory of "internally belonging to the Zang-fu organs and externally connecting with the limbs and joints". Acupuncture, one of the body surface stimulation therapies, can inhibit the inflammatory response via activating sympathetic/vagus nerve mediated anti-inflammatory pathways. The peripheral nerve innervating diffe-rent acupoints determines the different anti-inflammatory pathways of the autonomic nerve, and different acupuncture methods (stimulation form and stimulation amount) are important factors affecting the anti-inflammatory mechanism of the autonomic nerve. In the future, we should analyze the central integration mechanism between sympathetic nerve and vagus nerve regulated by acupuncture at the level of brain neural circuits, and clarify the "multi-target" advantage of acupuncture, so as to provide inspiration and reference for the study of neuroimmunological effects of acupuncture.

Objective: To observe the effect of acupuncture at "Houxi"(SI3) and "Huantiao"(GB30) on high mobility group box 1(HMGB1) protein and mRNA in spinal nerve trunk(SNT) of rats with lumbar disc herniation(LDH), so as to explore the mechanisms of acupuncture at this paired points on the treatment for LDH.
Methods: SD rats were randomly divided into sham operation, model, conventional acupuncture(CA) and paired points(PP) groups (with 8 rats in each group). The LDH model was established by injection of autologous suspension made from rats' own nucleus pulsus into the epidural space. Rats in the CA group received acupuncture treatment at bilateral "Weizhong"(BL40), "Dachangshu"(BL25) and "Shenshu"(BL23), while rats in the PP group received acupuncture at bilateral SI3 and GB30, 30 min each time, once daily for 14 consecutive days. The thermal pain threshold of bilateral hind feet of rats was detected by thermal pain stimulator. The contents of serum IL-1β, IL-6 and IL-8 of rats were detected by ELISA. Western blot and immunofluorescence were used to detect the expression of HMGB1 protein in the lumbar(L)5 SNT of rats. The relative expression of HMGB1 mRNA in L5 SNT was determined by qPCR. HE staining was used to observe the morphological changes of L5 SNT.
Results: Compared with the sham operation group, the thermal pain threshold of bilateral hind feet in the model group was decreased (P<0.05); compared with the model group, the thermal pain threshold of bilateral hind feet in the CA group and the PP group were increased (P<0.05). The expressions of HMGB1 protein and mRNA in L5 SNT, and the contents of serum IL-1β, IL-6 and IL-8 of rats in the model group were significantly increased(P<0.000 1, P<0.001) in contrast to the sham operation group. The expressions of HMGB1 protein and mRNA in L5 SNT, and the levels of serum IL-1β, IL-6 and IL-8 were significantly decreased (P<0.01, P<0.000 1, P<0.001, P<0.05) in the CA and PP group, in comparison with those of the model group. Compared with the CA group, the above indexes of rats in the PP group recovered more significantly (P<0.05,P<0.001, P<0.01,P<0.000 1). The histomorphological results showed scattered and various-sized nerve fibers, vacuolation, a large number of disintegrating myelin sheath and lysed Schwann cells in the model group. Myelin sheaths regeneration, regularly-arranged nerve fibers were seen in the CA group and the PP group, with more obvious histopathological recovery observed in the PP group than the CA group.
Conclusion: Acupuncture intervention inhibites the expressions of HMGB1 protein and mRNA in rats with LDH, and further reduces the production of IL-1β, IL-6 and IL-8, which is beneficial to inflammatory response inhibition and pain alleviation. The therapeutic effect of the PP group is more obvious than that of
