RESUMEN

INTRODUCTION: Acupuncture and related acupoint therapies have been widely used for smoking cessation. Some relevant systematic reviews (SRs) have been published. There is a need to summarize and update the evidence to inform practice and decision-making. METHODS: Eight databases were searched from their inception to December 2023. SRs, any randomized controlled trials (RCTs) comparing acupuncture therapies with sham acupuncture, pharmacotherapy, behavioral therapy, or no treatment, were included. The primary outcome was the abstinence rate. AMSTAR-2 was employed to assess the quality of SRs. An updated meta-analysis was conducted based on SRs and RCTs. Data were synthesized using risk ratios (RR) with 95% confidence intervals (CIs). The GRADE approach was employed to assess the certainty of the updated evidence. RESULTS: Thirteen SRs and 20 RCTs outside of the SRs were identified. The SRs were of low or very low quality by AMSTAR-2. Sixteen (80%) RCTs were at high risk of performance bias. Eight acupuncture and related acupoint therapies were involved. The short-term (≤6 months) abstinence rate outcome was summarized as follows. Most SRs suggested that filiform needle acupuncture or acupressure had a better effect than sham acupuncture, but the findings were inconsistent. The updated meta-analysis also suggested that filiform needle acupuncture was more effective than sham acupuncture (RR=1.44; 95% CI: 1.02-2.02; I2 = 66%; low certainty; 9 RCTs, n=1358). Filiform needle acupuncture combined with acupressure was comparable to nicotine patches (RR=0.99; 95% CI: 0.74-1.32; low certainty; 6 RCTs, n= 524). Acupressure was superior to counseling (RR=1.46; 95% CI: 1.14-1.87; I2=5%; low certainty; 8 RCTs, n=595). No serious adverse events were reported in these SRs or RCTs. CONCLUSIONS: Low certainty evidence suggests that filiform needle acupuncture and auricular acupressure appear to be safe and effective in achieving short-term smoking cessation. However, long-term follow-up data are needed.

RESUMEN

OBJECTIVES: To analyze the rules of acupoint selection and compatibility of acupuncture and moxibustion in treatment of inflammatory bowel disease (IBD) based on complex network technology and provide the reliable evidences for acupoint selection in treatment of this disease with acupuncture and moxibustion. METHODS: The clinical studies on acupuncture-moxibustion treatment of IBD were searched from the databases including CNKI, Wanfang, VIP, PubMed and Embase. The studies were screened and the acupoint prescriptions were extracted to set up the database of acupuncture-moxibustion treatment for IBD. Using Microsoft Excel 2021 software, the use times of acupoint, the use frequency (%) of acupoint, meridian tropism and the use of special point were imported. With SPSS Modeler 18.0 software adopted, the association rules were analyzed on the acupoint prescriptions. The acupoint co-occurrence network diagram, k-core network diagram, and community analysis diagram were drawn by Gephi 0.9.5 software. RESULTS: A total of 156 studies were included, composed of 175 acupoint prescriptions, 75 acupoints, with 1 378 use times in total and around 8 acupoints in one prescription. Regarding the top use frequency, Tianshu (ST25), Zusanli (ST36), Guanyuan (CV4), Zhongwan (CV12) and Pishu (BL20) were listed. The top meridians involved were the foot-yangming stomach meridian, the foot-taiyang bladder meridian and the Conception Vessel. The front-mu point had been used with the highest frequency among the special points. ST36 and ST25 were a pair of points with the highest frequency in treatment. The k-core hierarchical analysis was adopted to optimize acupoint prescriptions, and 22 core acupoints were obtained, i.e. ST25, ST36, CV4, CV12, BL20, Dachangshu (BL25), Shangjuxu (ST37), Shenshu (BL23), Qihai (CV6), Sanyinjiao (SP6), Mingmen (GV4), Xingjian (LR2), Yinlingquan (SP9), Neiting (ST44), Taichong (LR3), Xiajuxu (ST39), Shuifen (CV9), Shenque (CV8), Ganshu (BL18), Weishu (BL21), Hegu (LI4) and Quchi(LI11), which were classified into three core acupoint groups by community analysis. CONCLUSIONS: Through complex network analysis, it is found that the local acupoints on the chest and abdomen are generally selected in treatment with acupuncture-moxibustion for IBD, the combination of the nearby and distal points is considered simulta-neously, and the acupoint prescription is modified according to syndrome/pattern differentiation;and among special points, the front-mu point is widely used in treatment. All of these rules provide the ideas for the acupoint selection of acupuncture-moxibustion in treatment of IBD.

RESUMEN

OBJECTIVE: To investigate the relationship between the sensitization state of acupoints on the surface of the myocardial ischemia (MI) model mice and the changes in the electrophysiological properties of the dorsal root ganglion (DRG) neurons in the corresponding spinal cord segment, and its underlying mechanism. METHODS: Sixty-eight male C57BL/6J mice were randomly divided into control and model groups (34 mice in each group). The model group received an intraperitoneal injection of 160 mg/kg isoproterenol (ISO) to establish the MI model, and the control group received an injection of the same dose of normal saline as the model group. After modeling for about 6 days, MI proportion was measured by HE staining to verify the pathological changes in the heart tissue. Evans blue (EB) dye was injected into the tail vein of mice to reflect the size, location, distribution, and number of exudates on the body surface. Then, whole-cell membrane currents, intrinsic excitability and membrane properties of different types of DRG neurons were evaluated by electrophysiological experiment in vitro. RESULTS: Compared with the control group, the heart size was larger, with pathological outcomes showing enlarged myocardial hypertrophy, destroyed structure of cardiomyocytes, with mononuclear cell infiltration among the cardiomyocytes in the model group. Compared with the control group, the number of EB exudation points was significantly increased (P<0.01), which were mainly concentrated in the epidermis near the T1-T5 segment of the spinal cord, "Feishu" (BL13), "Jueyinshu" (BL14) and "Xinshu" (BL15) in the model group. Compared with the control group, the rheobase and action potential amplitude (APA) of DRG medium-sized neurons were obviously decreased (P<0.01, P<0.05), while the whole-cell membrane currents, the spike numbers, the average instantaneous frequency, and the average discharge frequency were markedly increased (P<0.01). There were no significant alterations in the membrane properties and intrinsic excitability induced by depolarized currents of small-sized neurons between groups. Compared with the control group, the whole-cell membrane currents, spike numbers, and the average instantaneous frequency were significantly increased in the model group(P<0.05, P<0.01) while rheobase was significantly decreased (P<0.05) in DRG medium-sized neurons labeled with biotin and CGRP. CONCLUSION: After the mice were modeled by ISO, the DRG medium-size neurons in the T1-T5 segment of the spinal cord may mediate the sensitization of acupoints on the body surface through their different neuronal membrane properties and intrinsic excitabilities.

RESUMEN

OBJECTIVE: To explore the rules of acupoint selection for aphasia treated with acupuncture and moxibustion using data mining technology. METHODS: From January 1, 2000 to April 1, 2022, the articles for clinical researches of acupuncture and moxibustion for aphasia published in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase were searched. Using Microsoft Excel 2021, the database was set up to analyze the use frequency of acupoint, meridian tropism, acupoint distribution and the use of specific points. SPSS26.0 was adopted for factor analysis, SPSS Modeler 18.0 was for association rule analysis of prescriptions, and Gephi 0.9.5 was to plot the co-occurrence network diagrams of acupoints and meridians. RESULTS: A total of 140 articles were collated, including 146 acupuncture and moxibustion prescriptions and 189 acupoints. The total use frequency of these acupoints was 1 211. Lianquan (CV 23), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20) and Yamen (GV 15) were the top 5 acupoints of the high use frequency for aphasia treated with acupuncture and moxibustion. Among 189 acupoints collected, the extra points and empirical points were mostly selected. The top 3 involved meridians were the governor vessel, the gallbladder meridian of foot-shaoyang and the conception vessel. These acupoints were mostly distributed on the head, face and neck region. The use frequency of five-shu points was the highest among the specific points. The acupoint combinations of high frequency referred to Yuye (EX-HN 13)-Jinjin (EX-HN 12), Yuye (EX-HN 13)-Lianquan (CV 23)-Jinjin (EX-HN 12), and Fengchi (GB 20)-Yuye (EX-HN 13)-Jinjin (EX-HN 12). Factor analysis extracted 10 common factors for acupoint compatibility in treatment of aphasia with acupuncture and moxibustion. CONCLUSION: In clinical treatment of aphasia with acupuncture and moxibustion, the local acupoints are preferred. The core acupoints include Lianquan (CV 23), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20) and Yamen (GV 15). The acupoint prescription is modified flexibly according to syndrome differentiation to enhance the therapeutic effect.

RESUMEN

To explore the regulating effect of acupuncture on pain based on the three dimensions of pain (pain sensation, pain emotion and pain cognition). The pain sensation is related to the body, the pain emotion is related to the seven emotions, the pain cognition is related to the mind of the five zang, and the three dimensions of pain interact with each other. Through the two ways of "regulating qi to treat mind" and "treating mind to regulate qi ", acupuncture comprehensively acts on pain sensation, pain emotion and pain cognition to achieve comprehensive regulation of pain.

RESUMEN

OBJECTIVE: To investigate the relationship between acupoint sensitization on the body surface and neuronal intrinsic excitability of the medium- and small-size dorsal root ganglion (DRG) neurons from the perspective of ion channel kinetics in mice with gastric ulcer. METHODS: Male C57BL/6J mice were randomly divided into control (n=32) and model groups (n=34). The gastric ulcer model was established by injection of 60% glacial acetic acid (0.2 mL/100 g) into the gastric wall muscle layer and submucosa near the pylorus in the minor curvature of the stomach. In contrast, the same dose of normal saline was injected in the same way in the control group. Six days after modeling, Evans blue (EB) solution was injected into the mouse's tail vein for observing the number and distribution of the exudation blue spots on the body surface. Histopathological changes of the gastric tissue were observed by H.E. staining. Then, whole-cell membrane currents and intrinsic excitability of medium- and small-size neurons in the spinal T9-T11 DRGs were measured by in vitro electrophysiology combining with biocytin-ABC method. RESULTS: In the control group, EB exudation blue spots were not obvious, while in the model group, the blue spots on the body surface were densely distributed in the area of spinal T9-T11 segments, the epigastric region, and the skin around "Zhongwan" (CV12) and "Huaroumen" (ST24) regions, and near the surgical incision region. Compared with the control group, the model group had a high level of eosinophilic infiltrates in the submucosa of gastric tissues, severe gastric fossa structure damage, gastric fundus gland dilation and other pathological manifestations. The number of exudation blue spots was proportional to the degree of inflammatory reaction in the stomach. In comparison with the control group, the spike discharges of type II of medium-size DRG neurons in T9-T11 segments were decreased, and the current of whole-cell membrane was increased, basic intensity was decreased (P<0.05), discharge frequency and discharge number were increased (P<0.01,P<0.000 1); while the discharges of type I small-size DRG neurons were decreased, those of type II neurons increased, the whole-cell membrane current was decreased, and discharge frequency and discharge number were decreased (P<0.01, P<0.000 1). CONCLUSION: Both the medium- and small-size DRG neurons from the spinal T9-T11 segments involve in gastric ulcer-induced acupoint sensitization via their different spike discharge activities. And intrinsic excitability of these DRG neurons can not only dynamically encode the plasticity of acupoint sensitization, but also can help us understand the neural mechanism of acupoint sensitization induced by visceral injury.

RESUMEN

OBJECTIVE: To observe the effect of early electroacupuncture(EA) intervention on ionized calcium binding adapter molecule 1 (Iba-1), tyrosine hydroxylase (TH) and tumor necrosis factor-α (TNF-α) in Parkinson's disease (PD) mice, so as to explore its neuroinflammation mechanism in treating PD. METHODS: A total of 24 male C57BL/6J mice (9 weeks old) were randomly divided into control, model and EA groups, with 8 mice in each group. The PD model was established by long-term low dose subcutaneous injection of rotenone. Started at the same time with modeling, EA (2 Hz/100 Hz, 1 mA) was applied to "Shenting"(GV24), bilateral "Tianshu"(LI11), "Quchi"(ST25), and "Shangjuxu"(ST37) for 15 min, once a day for 8 weeks. The motor function was assessed by rotorod test and step length test. The expression levels of Iba-1 and TH proteins in substantia nigra pars compacta (SNpc) was detected by Western blot and immunohistochemistry. The expression level of TNF-α protein in colon tissue was examined by Western blot and immunofluorescence staining. RESULTS: Compared with the control group, the fall latency shortened at 4, 6, and 8 weeks after modeling (P<0.01) and the step length of hind limbs shortened at 5 and 7 weeks after modeling (P<0.01), the expression levels of Iba-1 in SNpc and TNF-α in colon tissue were increased (P<0.01), and the expression level of TH in SNpc was decreased (P<0.01) in the model group. Compared with the model group, the fall latency prolonged at 6 and 8 weeks after modeling (P<0.01) and the step length of hind limbs prolonged at 5 and 7 weeks after modeling (P<0.01), the expression levels of Iba-1 in SNpc and TNF-α in colon tissue were decreased (P<0.01, P<0.05), and the expression level of TH in SNpc was increased (P<0.05, P<0.01) in the EA group. CONCLUSION: Early EA intervention can delay the occurring time of motor disfunction, alleviated the loss of substantia nigra dopaminergic neurons, and exerted a good neuroprotective effect on the degenerative changes in rotenone-induced PD mice, which may be related to its effects in alleviating the intestinal inflammation, inhibiting the activation of microglia, thereby reducing the neuroinflammation.

RESUMEN

This study investigated the potential active components against cyclooxygenase-2(COX-2) from Trachelospermi Caulisetfolium and explored the pharmacodynamic material basis.A pharmacophore-based virtual screening method was adopted to establish a COX-2 ligands-based HipHop pharmacophore model on the basis of the information on compounds with COX-2 inhibitory activity reported in published research articles.The reported components in Trachelospermi Caulisetfolium were collected to establish the compound library and matched with the pharmacophores.Subsequently, the matched small molecule compounds underwent molecular docking with COX-2 targets(PDB ID: 3 LN1), and the interaction of potential active monomers and COX-2 was further explored by molecular dynamics.The antiepileptic effect of active monomer arctigenin(15) was determined based on the pentylenetetrazole(PTZ)-induced seizure model, and its modulatory effect on the COX-2 level was evaluated.A compound library containing 118 chemical constituents in Trachelospermi Caulisetfolium was established by literature retrieval.The preferred pharmacophore 04 was selected through test set verification for virtual screening of the compound library of Trachelospermi Caulisetfolium.After matching, six potential constituents with COX-2 inhibitory activity were obtained.The interaction of five compounds with COX-2 and COX-1 was analyzed by molecular docking, and 10 ns molecular dynamics was performed on two compounds.Compound 15 could prolong the latent time of PTZ-induced seizures at medium and high doses, improve the anxiety-and depression-like behaviors induced by PTZ, reduce the expression level of COX-2, and decrease the number of COX-2 immuno-posi-tive cells in the hippocampal CA1 region.The results showed that it was reasonable to investigate the components in Trachelospermi Caulisetfolium with COX-2 inhibitory activity based on virtual screening and activity evaluation.

RESUMEN

OBJECTIVE: To compare the effect of electroacupuncture (EA) on "Guanyuan" (CV4) or sensitization points in mice with polycystic ovary syndrome (PCOS), so as to explore its mechanisms underlying improvement of PCOS. METHODS: In the first part of this study, 26 female ICR mice were randomized into control group (8 mice) and model group (18 mice). The PCOS model was established by gavage of bisphenol A (BPA) at a dose of 100 mg/kg, and the control group were gavage of equal volume of corn oil, once daily, 5 days a week for 4 conse-cutive weeks. Evans blue (EB) dye (0.1 mL/10 g) was injected into the caudal vein after modeling. The size, number and distribution of EB exudation points at the skin were observed. In the second part of this study, 32 mice were randomized into control, model, EA-CV4 and EA-sensitization points groups (8 mice in each group). EA (2 Hz, 2 mA) was applied to the sensitization points or CV4 for 20 min, once daily, 5 days a week for 4 conse-cutive weeks. The body weight was measured once a week for 8 consecutive weeks. The behavior changes were evaluated by open field test and elevated plus maze test. H.E. staining was used to observe the histopathologic changes of the ovary tissue. Serum level of estradiol (E2) was measured by ELISA. The expressions of estrogen receptor α (ER-α) in ovarian and uterine tissues were detected by Western blot and immunofluorescence. RESULTS: (1) In PCOS mice, the EB exudation points were found to overlap the lower abdomen, lumbosacral, chest, back and lower limbs regions, and the number of EB points was significantly more than that of the control group (P<0.01). (2) After the intervention and compared with the control group, the ovaries showed polycystic changes and an increase of atresia follicles with a larger diameter, the activity time in the central area, the total distance of movement, the times of open-arm entries, the duration in open-arm, the serum E2 content and the expression of ER-α in ovarian tissue were significantly decreased (P<0.01, P<0.05), while the mice's body weight and the expression of ER-α in uterine tissue were increased (P<0.05) in the model group. After the intervention and compared with the model group, a small number of normal follicles and corpus luteum were observed under microscope, the activity time in the central area, the total distance of movement, the times of open-arm entries, the duration in open-arm, the serum E2 content and the expression of ER-α in ovarian tissue were significantly increased (P<0.05, P<0.01), while the mice's body weight and the expression of ER-α in uterine tissue was decreased (P<0.05) in both EA-CV4 and EA-sensitization points groups. CONCLUSION: EA at sensitization points and CV4 can regulate the expression of estrogen and ER-α in PCOS mice, and improve the anxiety like behavior. EB exudation points on the body surface can not only reflect the functional changes of organs, but also treat diseases through body surface stimulation, suggesting a dual role in diagnosis and treatment.

RESUMEN

OBJECTIVE: To observe the effect of electroacupuncture(EA) intervention on the behavior, colon and midbrain substantia nigra α-synuclein(α-syn) expression in Parkinson's disease (PD) mice, so as to explore the mechanism of early EA on prevention of PD. METHODS: C57BL/6J mice were randomly divided into blank, model and EA groups, with 8 mice in each group. The PD mouse model was established by subcutaneous injection of rotenone. Mice in the EA group received EA (2 Hz, 1 mA) at "Quchi"(LI11), "Shangjuxu"(ST37) and acupuncture at "Shenting" (GV24)and "Tianshu"(ST25) for 10 min once daily, with 7 d for a course, a total of 8 courses. Behavioral tests of hanging and climbing poles were carried out before, during and after modeling. The expressions of a-syn in substantia nigra and colon were detected by Western blot and immunohistochemistry or immunofluorescence. RESULTS: After 8 weeks of modeling, the mice in the model group showed symptoms such as listlessness, dim hair color, coldness and curling up. Compared with the blank group, the hanging score of the model group was significantly lower (P<0.01), the pole climbing time and the expressions of α-syn protein in colon and substantia nigra were significantly increased (P<0.01). Following intervention, mice in the EA group were always in good mental state, with shiny fur and stable body weight. The hanging scores was significantly higher and the pole climbing time and the expressions of α-syn protein in colon and substantia nigra were significantly down-regulated (P<0.05, P<0.01) in the EA group relevant to the model group. CONCLUSION: Early EA intervention can delay the onset of PD induced by rotenone, which may be related to its effect in reducing the expression of α-syn in midbrain substantia nigra and colon.

RESUMEN

Previous studies demonstrated that Tiaoxin Recipe (TXR), a traditional Chinese medicinal prescription, could alleviate cognitive dysfunction. NT-1, an active constituent isolated from this prescription under guidance of bioactive evaluation, was preliminarily proved to enhance the ability of spatial learning and memory in rats. In the present study, using hippocampal slice preparations, we investigated the mechanisms by which NT-1 improves cognitive dysfunction contributed to corticosterone (CORT). NT-1 ameliorated the inhibition of LTP by CORT more significantly than TXR did. These results suggested that enhancing LTP induction is one mechanism by which NT-1 improves spatial learning and memory impaired by CORT.

RESUMEN

OBJECTIVE: To study the effect of the active fraction of Tiaoxin recipe (TXR-A), in inhibiting long-term potentiation (LTP) induced by beta amyloid protein (beta-AP) in CA1 area of rats' hippocampal slices. METHODS: The population spike (PS) in CA1 area of hippocampal slices incubated in different medium was recorded before and after LTP was evoked by a 100 Hz, 100 trains high frequency stimulation (HFS), using extracellular microelectrode recording techniques. RESULTS: The amplitude of PS significantly decreased after HFS in hippocampal slices incubated in medium containing 0.2 micromol/L beta-AP for more than 1.5 hour, as compared with that incubated in normal cerebrospinal fluid, the difference was significant, suggesting that beta-AP could inhibit LTP in hippocampal slices. The average amplitude of PS in slices incubated in beta-AP containing medium could be significantly enhanced by adding high-concentration TXR-A or TXR into the medium, and TXR-A showed a better effect of enhancing than that of TXR, indicating that TXR-A could increase the amplitude of LTP. CONCLUSION: TXR-A may be the chief ingredient extracted from TXR for improving beta-AP induced LTP in CA1 area of rats' hippocampus, to antagonise the inhibition of beta-AP on LTP is possibly one of the mechanisms for its intelligence benefiting action.

RESUMEN

Interleukin (IL)-1beta is often characterized as the prototypic proinflammatory cytokine but is involved in various pathophysiological conditions in the central nervous system (CNS). A whole-cell recording technique was used to observe its effect on N-methyl-D-aspartate (NMDA)-evoked currents and spontaneous synaptic activity in cultured rat hippocampal neurons. The results showed that the frequencies but not the amplitudes of spontaneous excitatory postsynaptic currents (sEPSC) and miniature excitatory postsynaptic currents (mEPSC) were decreased by 10 or 100 ng/ml IL-1beta. IL-1beta at these concentrations also increased the NMDA receptor-mediated current. In addition, 10 ng/ml IL-1beta significantly increased the amplitude of the voltage-dependent Ca2+ current (I(Ca)). The increase in I(Ca) following treatment of cultures with IL-1beta resulted mainly from an increase in L-type current. These data suggest that IL-1beta modulates hippocampus-related functions via its effect on synaptic activity and Ca2+ signaling in neurons.

According to Wang Bing's preface, when arranging Su wen (Plain Questions), he applied different editions of the book. But, he didn't indicate which edition was applied as the mother edition. By analyzing materials from Wang's preface, newly produced Plain Questions, etc. though the mother edition he used was based on the edition of the Liang dynasty, it was not the edition of Quan Yuanqi, but a clandestine edition of Master Zhang. Some of the chapters and texts of now extant Plain Questions editions should be the old original of the mother edition. The mother edition, Quan Yuanqi's edition, Zhen jiu jia yi jing (A-B Classic of Acupuncture and Moxibustion) and Tai su (Extremely Plain) are derived from different editions.
