[Transdermal patches containing Cassia seed extract applied at the navel for slow transit constipation in rats: therapeutic effect and analysis of the spectrum-effect relationship].

OBJECTIVE: To explore the therapeutic effect of transdermal patches containing Cassia seed extract applied at the navel on slow transit constipation (STC) in rats and explore the spectrum-effect relationship of the patches. METHOD: In a STC rat model established by gavage of compound diphenoxylate suspension for 14 days, the transdermal patches containing low, medium and high doses of Cassia seed extract (41.75, 125.25, and 375.75 mg/kg, respectively) were applied at the Shenque acupoint on the abdomen for 14 days after modeling, with constipation patches (13.33 mg/kg) as the positive control. After the treatment, fecal water content and intestinal propulsion rate of the rats were calculated, the pathological changes in the colon were observed with HE staining. Serum NO and NOS levels and the total protein content and NO, NOS and AChE expressions in the colon tissue were determined. HPLC fingerprints of the transdermal patches were established, and the spectrum-effect relationship between the common peaks of the patches and its therapeutic effect were analyzed. RESULTS: Treatment with the transdermal patches containing Cassia seed extract significantly increased fecal water content and intestinal propulsion rate of the rat models, where no pathological changes in the colon tissue were detected. The treatment also suppressed the elevations of serum and colonic NO and NOS levels and reduction of AChE in STC rats. Twenty-eight common peaks were confirmed in the HPLC fingerprints of 6 batches of Cassia seed extract-containing patches. Analysis of the spectrum-effect relationship showed that autrantio-obtusin had the greatest contribution to the therapeutic effect of the patches in STC rats. CONCLUSION: The Cassia seed extract-containing patches alleviates STC in rats via synergistic actions of multiple active ingredients in the extract, where autrantio-obtusin, rhein, chrysoobtusin, obtusin, obtusifolin, emodin, chrysophanol, and physcion are identified as the main active ingredients.

Clinical study on improving the function of female bladder in controlling urine by acupuncture Zhibian (BL54) under ultrasound guidance.

OBJECTIVE: To observe the effect of acupuncture Zhibian (BL54) on the function of the bladder in controlling urine in women under ultrasound. METHOD: 74 healthy subjects were randomly divided into deep acupuncture group of 37 cases and shallow acupuncture group of 37 cases. Under the guidance of ultrasound, the two groups of subjects were acupunctured at bilateral BL54. The deep acupuncture group was acupunctured to the pudendal nerve, and the shallow acupuncture group was acupunctured to the superficial fascia. Ultrasound was used to observe the peak systolic velocity (PSV), time average maximum velocity (TAMX), end diastolic velocity (EDV), pulsation index (PI), resistance index (RI) of the pudendal arteries, and bladder volume of two groups of subjects before and after acupuncture. The anatomical hierarchical structure of bilateral BL54 and score of Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) of all subjects was measured. RESULT: After acupuncture, the PSV, TMAX of the pudendal artery, bladder volume, and the Score of C-MASS Scale in the deep acupuncture group were higher than in the shallow acupuncture group (P < 0.05). The RI of the pudendal arteries in the shallow acupuncture group decreased compared to before acupuncture (P < 0.05). CONCLUSION: Acupuncture at the BL54 can increase the blood flow velocity of the pudendal artery, improve the function of the bladder in controlling urine in women, and different depths of acupuncture will have different therapeutic effects.

Operation Procedure and Precautions of Thread-Embedding Acupuncture Therapy in Alzheimer.

Thread-embedding therapy (TEAT) is a treatment that prevents and manages diseases by inserting a biodegradable suture into an acupoint, providing long-lasting stimulation. TEAT is a simple approach that avoids the discomfort of regular acupuncture and provides sustained therapeutic effects. This article discusses the potential impact of TEAT on the learning and memory abilities of rats with Alzheimer's disease-like symptoms. Since chemically induced neuronal degeneration and cognitive impairments in rats does not entirely reflect the true pathological changes observed in Alzheimer's disease. Consequently, our research group has designated these manifestations as Alzheimer's disease-like symptoms. A protocol has been established to outline the selection of acupoints, the operation process, and necessary precautions for the head and lower back. The experiment was conducted on three groups: a control group, a model group, and a TEAT group, each containing 6 rats. To induce Alzheimer's disease-like symptoms, rats were intraperitoneally injected with D-galactose for 7 weeks (49 days). The rats in the TEAT group received acupoint catgut embedding treatment. Following the intervention period, a Morris Water Maze (MWM) was conducted to evaluate the rats' learning and memory. Subsequently, the rats were sacrificed, and their brain tissue was examined. A histological examination was performed to understand the effects of TEAT on the pathology of rats exhibiting symptoms of Alzheimer's disease. This study suggests that TEAT may improve learning and memory in rats with Alzheimer's disease-like symptoms, indicating a potentially promising new treatment approach for this neurodegenerative condition.

[Clinical effect of acupuncture combined with medication on diabetic peripheral neuropathy and its influence on serum lipid metabolism].

OBJECTIVE: To observe the clinical effect on diabetic peripheral neuropathy (DPN) treated with acupuncture combined with medication and explore its effect mechanism. METHODS: Sixty-two patients of DPN were randomly divided into a combined therapy group (31 cases) and a medication group (31 cases, 2 cases dropped out); besides, 20 healthy subjects were recruited as a normal group. On the base of routine intervention, in the medication group, thioctic acid capsules were administrated orally, 0.2 g each time, 3 times a day. In the combined therapy group, besides the medication as the medication group, acupuncture was performed on bilateral Quchi (LI 11), Waiguan (TE 5), Hegu (LI 4), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) and the needles were retained for 30 min, acupuncture was delivered once daily, 6 times a week. The duration of treatment was 4 weeks in the two groups. The score of Toronto clinical scoring system (TCSS), the nerve conduction velocity of median nerve (MN) and common peroneal nerve (CPN) were observed before and after treatment in the two intervention groups; and the serum lipid metabolism was detected before and after treatment in the two intervention groups and the normal group. RESULTS: Compared with that before treatment, the scores of TCSS were reduced in the combined therapy group and the medication group (P<0.05) after treatment, and the score decrease in the combined therapy group was larger than that of the medication group (P<0.001). The motor nerve conduction velocity and the sensory nerve conductive velocity of MN and CPN after treatment all increased in the combined therapy group and the medication group compared with those before treatment (P<0.05), and the improvements in the combined therapy group were larger than those of the medication group (P<0.001). Before treatment DPN patients had 365 differential lipid metabolites, including sphingosine (SPH, d18:0), involved in the inositol phosphate metabolism, compared with the subjects of the normal group. There were 103 differential lipid metabolites in the medication group before and after treatment, including lysophosphatidyl ethanolamine (LPE, 18:1/0:0), participated in glycerophospholipid metabolism. In the combined therapy group, before and after treatment, there were 99 differential lipid metabolites, including lysophosphatidylcholine (LPC, 18:0/0:0), participated in the neuroactive ligand-receptor interaction. Acupuncture greatly affected 50 lipid metabolites such as lysophosphatidic acid (LPA, 0:0/22:6), LPA(0:0/18:2) and LPC(O-18:0), which was mainly involved in glycerophospholipid metabolism. CONCLUSION: Acupuncture combined with medication ameliorates the symptoms and the nerve conduction velocity in DPN patients, which may be related to the regulation of serum lipid metabolism.

[Effect of transcutaneous electrical acupoint stimulation on postoperative cough in lung cancer patients undergoing video-assisted thoracoscopic surgery].

OBJECTIVE: To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) for alleviating postoperative cough in lung cancer patients undergoing video-assisted thoracoscopic surgery. METHODS: A total of 110 patients with lung cancer undergoing video-assisted thoracoscopic surgery were randomly divided into a TEAS group (55 cases, 2 cases dropped out) and a sham-TEAS group (55 cases, 4 cases dropped out). In the TEAS group, TEAS was delivered 30 min before anesthesia and on day 1 to day 4 after operation separately, with disperse-dense wave, in frequence of 2 Hz/100 Hz. The acupoints included Feishu (BL 13), Pishu (BL 20), Shenshu (BL 23), Hegu (LI 4), Lieque (LU 7) and Taixi (KI 3) on the both sides. In the sham-TEAS group, at the same time points and same acupoints as the TEAS group, the electrode pads were attached to the acupoints, but without electric stimulation. The interventions were given 30 min each time, once daily in the two groups. The incidence of cough and the scores of visual analogue scale (VAS) for cough on the first day (T1), the third day (T2), the fifth day (T3), 1 month (T4) and 3 months (T5) after operation, as well as the scores of the Leicester cough questionnaire (LCQ) on T4 and T5 were compared between the two groups; the contents of serum C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were detected before surgery (T0) and at T1, T2 and T3. The first flatus time, the first defecation time, the first ambulation time, the postoperative hospital day and the incidence of postoperative nausea and vomiting were compared between the two groups. RESULTS: Compared with the sham-TEAS group, the cough incidence at T3 and cough VAS scores at T1 to T5 were lower in the TEAS group (P<0.05, P<0.01), and the LCQ scores at T4 and T5 were higher (P<0.05). The serum contents of CRP, IL-6 and TNF-αat T1 to T3 in the TEAS group were lower than those of the sham-TEAS group (P<0.01). The first flatus time, the first defecation time and the first ambulation time were earlier (P<0.05, P<0.01); and the postoperative hospital day was shorter (P<0.05) and the incidence of postoperative nausea and vomiting was lower (P<0.05) in the TEAS group when compared with those of the sham-TEAS group. CONCLUSION: TEAS relieves cough in lung cancer patients undergoing video-assisted thoracoscopic surgery, improves quality of life and promotes the early postoperative recovery.

OBJECTIVE: To observe the clinical effect of repetitive transcranial acupuncture stimulation (rTAS) combined with electroacupuncture (EA) in treatment of acute facial palsy with retroauricular pain. METHODS: Sixty-eight patients of acute facial palsy with retroauricular pain were randomly divided into an observation group (34 cases, 3 cases dropped out) and a control group (34 cases, 3 cases dropped out). On the basis of conventional therapy, in the control group, Yangbai (GB 14), Cuanzhu (BL 2), Sibai (ST 2), Quanliao (SI 18), Dicang (ST 4), Yifeng (TE 17), Qianzheng (Extra point) and Taiyang (EX-HN 5) on the affected side, and bilateral Hegu (LI 4) were selected. EA was attached to Yangbai (GB 14) and Cuanzhu (BL 2), and Sibai (ST 2) and Dicang (ST 4), respectively, using intermittent wave. In the observation group, on the basis of the regimen as the control group, rTAS was delivered at Baihui (GV 20) and the 1/5 of the lower motor area on the bilateral sides; EA of dense wave was given at the sites of the mastoidⅠand Ⅱ. The intervention of each group was delivered once a day, 6 times a week as one course for 4 courses and taking a day off every course. Before treatment and at the moment after the first treatment completion, the score of visual analogue scale (VAS) was observed in the two groups and the days of retroauricular pain were recorded. Before and after treatment, the score of Sunnybrook facial grading system (SFGS), the grade of House-Brackmann facial nerve function evaluation system (H-B), the latency and amplitude of the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve, were observed in the patients of two groups and the clinical effect was compared between the two groups after treatment. RESULTS: After treatment, SFGS score was increased (P<0.05), H-B grade was improved (P<0.05), the latency was shortened in the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve (P<0.05) and its amplitude elevated (P<0.05) when compared with those before treatment in the two groups. In the observation group, SFGS score was higher (P<0.05), H-B grade was superior (P<0.05), the latency was shorter in the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve (P<0.05) and its amplitude was higher (P<0.05) when compared with those of the control group after treatment. After the completion of the first treatment, VAS score of either group was reduced in comparison with that before treatment (P<0.05), and the score in the observation group was lower than that of the control group (P<0.05). The duration of retroauricular pain was shortened in the observation group when compared with that of the control group (P<0.05). The total effective rate was 87.1% (27/31) in the observation group, which was higher than 77.4% (24/31) of the control group (P<0.05). CONCLUSION: The rTAS combined with EA is effective for reducing neurologic impairment of acute facial palsy and alleviating retroauricular pain in the patients.

[Regulation of electroacupuncture on non-canonical pathway of hepatocellular pyroptosis in rats with nonalcoholic fatty liver disease].

OBJECTIVE: To observe the effect and mechanism of electroacupuncture (EA) on non-canonical pathway of hepatocellular pyroptosis in nonalcoholic fatty liver disease (NAFLD). METHODS: Sixty male SD rats were randomly divided into a normal diet group (n=15) and a high fat modeling group (n=45). The rats in the high fat modeling group were fed with customized high fat diet for 8 weeks to establish NAFLD model. Thirty successfully modeled rats were selected and randomly divided into a model group (n=10), an EA group (n=10) and a non-acupoint with shallow needling group (n=10), and 10 rats were randomly selected from the normal diet group as the control group additionally. In the EA group, EA was applied at bilateral "Fenglong" (ST 40) and "Ganshu" (BL 18), with disperse-dense wave, in frequency of 4 Hz/20 Hz and in intensity of 3 mA. In the non-acupoint with shallow needling group, shallow needling was delivered at points 5 mm from bilateral "Fenglong" (ST 40) and "Ganshu" (BL 18), the EA stimulation parameters were same as the EA group. The intervention was given once a day, 20 min a time, 5 days a week for 4 weeks in the two groups. After intervention, the liver morphology was observed by oil red "O" staining, the serum levels of lipopolysaccharide (LPS), interleukin (IL)-1ß, IL-18 and tumor necrosis factor-α (TNF-α) were detected by ELISA, the protein expression of gasdermin D (GSDMD), GSDMD-N, cysteine aspartic acid specific protease-11 (Caspase-11), IL-1ß, IL-18 and TNF-α in liver tissue were detected by Western blot, the mRNA expression of GSDMD, Caspase-11, IL-1ß, IL-18 and TNF-α in liver tissue was detected by real-time PCR in rats of each group. RESULTS: In the model group, vacuoles in different size were found in the hepatocellular cytoplasm, and the fat droplets were in schistose accumulation. Compared with the model group, the hepatocellular fat droplets and the degree of hepatic steatosis were reduced in the EA group and the non-acupoint with shallow needling group. Compared with the control group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were increased (P<0.01), the protein and mRNA expression of GSDMD, Caspase-11, IL-1ß, IL-18, TNF-α as well as the protein expression of GSDMD-N in the liver tissue were increased (P<0.01) in the model group. Compared with the model group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were decreased (P<0.01), the protein and mRNA expression of GSDMD, IL-1ß, IL-18 and TNF-α in the liver tissue were decreased (P<0.01), the protein expression of GSDMD-N and the mRNA expression of Caspase-11 in the liver tissue were decreased (P<0.01) in the EA group and the non-acupoint with shallow needling group. Compared with the model group, the protein expression of Caspase-11 in the liver tissue was decreased (P<0.01) in the EA group. Compared with the non-acupoint with shallow needling group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were decreased (P<0.01), the protein and mRNA expression of GSDMD, Caspase-11, IL-1ß and IL-18 in the liver tissue were decreased (P<0.01), the protein expression of GSDMD-N and the mRNA expression of TNF-α in the liver tissue were decreased (P<0.01) in the EA group. CONCLUSION: EA can inhibit hepatocellular pyroptosis in NAFLD rats, and its mechanism may be related to reducing the serum level of LPS, and down-regulating the expression of the non-canonical pathway related factors i.e. GSDMD, GSDMD-N, Caspase-11, IL-1ß, IL-18 and TNF-α.

[Acupoint application for Hashimoto's thyroiditis with liver-qi stagnation: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy and safety of acupoint application for Hashimoto's thyroiditis (HT) with liver-qi stagnation. METHODS: One hundred and fifty patients of HT with liver-qi stagnation were randomly divided into an acupoint application group (75 cases, 11 cases were excluded, 5 cases dropped out) and a control group (75 cases, 12 cases excluded, 3 cases dropped out). Based on the health education combined with conventional western medicine treatment, the patients in the acupoint application group were treated with acupoint application, while the patients in the control group were treated with placebo acupoint application. Shenque (CV 8), bilateral Yongquan (KI 1), Yeshi, and ashi point were selected in both groups, with Yeshi treated once a week and the remaining acupoints treated every other day, for a total of 4 weeks. The serum levels of thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb), free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH), as well as the thickness of thyroid left lobe, right lobe, and isthmus, TCM symptom score, hospital anxiety and depression scale (HADS) score, and MOS 36-item short form health survey (SF-36) score were compared between the two groups before and after treatment. Adverse reactions in both groups were observed. RESULTS: Compared with before treatment, in the acupoint application group, the serum levels of TgAb and TPOAb were reduced after treatment (P<0.05), and the scores of role physical (RP), body pain (BP), vitality (VT), role emotional (RE), and mental health (MH) in SF-36 were increased after treatment (P<0.01, P<0.001). The thickness of the thyroid isthmus after treatment was smaller than that before treatment (P<0.05), and the TCM symptom scores and HADS anxiety (HADS-A) scores after treatment were lower than those before treatment (P<0.001, P<0.01) in both groups. In the control group, the scores of physical function (PF), RP, BP, VT, and RE in SF-36 after treatment were higher than those before treatment (P<0.05, P<0.01, P<0.001). There was no statistically significant difference in serum FT3, FT4, and TSH levels within the groups (P>0.05). There was no statistically significant difference in the above indexes between the two groups (P>0.05). The incidence of adverse reactions in the acupoint application group and the control group was 20.0% (15/75) and 10.7% (8/75) respectively, with skin allergy being the main adverse reaction. CONCLUSION: Acupoint application could reduce the serum levels of TgAb and TPOAb in patients of HT with liver-qi stagnation, alleviate thyroid enlargement, improve TCM symptoms and anxiety, and improve quality of life, with safe and reliable clinical efficacy.

The clinical experience of Shao's needling technique for post-stroke depression is introduced. Professor SHAO Jingming proposes that the main pathogenesis of this condition lies in the "imbalance of body and spirit," with its onset closely related to the heart, liver, spleen, and kidney. In clinical practice, based on the principle of "treating both the body and spirit", "three acupoints for treating the spirit" including Dazhui (GV 14), Fengchi (GB 20), and Baihui (GV 20) are selected, combined with back-shu points such as Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), and Shenshu (BL 23). The nu-needle manipulation method is applied. The treatment focuses on both physical and mental aspects, achieving remarkable therapeutic effects.

["To be meridian or collateral" in meridian-collateral differentiation].

Identifying the study subject, "to be in meridian or collateral", is the first step of meridian-collateral differentiation. Combined with the ancient literature and clinical practice of acupuncture and moxibustion, the methods of identifying "to be in meridian or collateral" and its values are elaborated. Through analyzing the onset location of symptoms and the body layers of lesions, as well as the palpation and observation in meridian-collateral detection, "to be meridian" or "to be collateral" is identified in disease diagnosis. It may guide the choice of techniques of acupuncture and moxibustion. Identifying "to be meridian or collateral" is crucial in meridian-collateral differentiation, which not only contributes to improving the therapeutic effect of acupuncture and moxibustion, but also to better recognizing diseases and understanding the relevant concepts of techniques of acupuncture and moxibustion in view of acupuncture and moxibustion, and perfecting the system of meridian-collateral differentiation.

The occurrence and severity of nausea and vomiting after chemotherapy were recorded after each treatment on the 1st to 7th days of chemotherapy in the two groups, the complete remission rate was evaluated. The KPS score, quality of life scale score before and after treatment and incidence of myelosuppression were compared between the two groups. RESULTS: On the 2nd to 4th days of chemotherapy, the incidence and severity of nausea and vomiting in the observation group were lower than those in the control group (P<0.05), the complete remission rates of nausea and vomiting were higher than those in the control group (P<0.05). After treatment, the KPS score in the observation group was higher than those before treatment and in the control group (P<0.05). After treatment, the scores of emotional function and overall health status in the observation group were higher than those before treatment and in the control group (P<0.05), the scores of fatigue, pain, insomnia, loss of appetite and diarrhea were lower than those before treatment and in the control group (P<0.05). The incidence of myelosuppression in the observation group was 20.0% (6/30), which was lower than 46.7% (14/30) in the control group (P<0.05). CONCLUSION: Heat-sensitive moxibustion combined with tropisetron hydrochloride can effectively reduce nausea and vomiting after chemotherapy in patients with malignant tumor, improve the quality of life, relieve the myelosuppression caused by chemotherapy drugs.

[LU Yonghui's clinical experience of hierachical acupuncture at acupoints of conception vessel in treatment of benign prostatic hyperplasia].

The paper introduces professor LU Yonghui 's academic thought and clinical experience in treating benign prostatic hyperplasia (BPH). It is believed that the pathogenesis of BPH includes retarded qi movement of triple energizers and dysfunction of the bladder in qi activity, resulting in impairment of water metabolism, and difficulty in micturition occurs. In treatment, acupuncture is delivered at the muscle region (membrane) of the body to promote qi circulation. The needles are inserted at the acupoints of conception vessel to different depths. The shallow insertion is operated at Qihai (CV 6) and Guanyuan (CV 4) to benefit qi movement of triple energizers, the moderate insertion is at Zhongji (CV 3), the front-mu point of the bladder, to benefit the intersections (membranes) of triple energizers, and the deep insertion is at Qugu (CV 2) to work at the internal organ, regulate qi, remove obstruction. As a result, the qi movement of triple energizers is improved, the function of the bladder in qi activity recovered, urination ameliorated and the retention of urine cured.

[Rules of acupoint selection and pattern-acupoint relationship in treatment with acupuncture and moxibustion for endometriosis based on complex network analysis technology].

OBJECTIVE: To explore the rules of acupoint selection and pattern-acupoint relationship in treatment with acupuncture and moxibustion for endometriosis (EMs) based on complex network analysis technology. METHODS: The articles for clinical trial of EMs treated with acupuncture and moxibustion were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library from the inception of the databases to December 14, 2022. Using Microsoft Excel 2019 software, the database was established to collect the use frequency of acupoint, meridian tropism, location and pattern-acupoint relationship. SPSS Modeler 18.0 Apriori algorithm was adopted to conduct the association rule analysis, Cytoscape3.7.2 software was used to plot the complex co-occurrence network map; and SPSS Statistics 26.0 was adopted to perform hierarchical cluster analysis on high-frequency acupoints and a tree diagram was drawn. RESULTS: A total of 163 articles were included, and 167 core acupoint prescriptions and 74 pattern-associated acupoint prescriptions were extracted, involving 92 acupoints, with a cumulative frequency of 1 223 times. The top five acupoints with the highest use frequency were Guanyuan (CV 4), Sanyinjiao (SP 6), Zhongji (CV 3), Zigong (EX-CA 1) and Qihai (CV 6). The selected acupoints were mostly distributed in the chest, abdomen and lower limbs; and the involved meridians included the conception vessel, the spleen meridian of foot-taiyin and the stomach meridian of foot-yangming. The acupoint compatibility of high frequency referred to Guanyuan (CV 4) - Sanyinjiao (SP 6), Guanyuan (CV 4) - Zhongji (CV 3), and Guanyuan (CV 4) - Zigong (EX-CA 1). The close association was presented among Guanyuan (CV 4), Sanyinjiao (SP 6), Qihai (CV 6) and Zhongji (CV 3), which had the strongest connection with the other acupoints; among the top 25 acupoints with the highest use frequency, 5 acupoint prescriptions with high frequency were obtained by the cluster analysis. Guanyuan (CV 4), Qihai (CV 6), Sanyinjiao (SP 6), Zigong (EX-CA 1) and Zhongji (CV 3) were selected for cold and blood stagnation; Guanyuan (CV 4), Sanyinjiao (SP 6), Zhongji (CV 3), Dahe (KI 12) and Taixi (KI 3) for kidney deficiency and blood stagnation; Zhongji (CV 3), Guanyuan (CV 4), Sanyinjiao (SP 6), Xuehai (SP 10) and Diji (SP 8) for qi and blood stagnation; Qihai (CV 6), Guanyuan (CV 4), Zusanli (ST 36), Xuehai (SP 10), and Zigong (EX-CA 1) for qi deficiency and blood stagnation; Sanyinjiao (SP 6), Fenglong (ST 40), Zhongliao (BL 33), Ciliao (BL 32) and Xialiao (BL 34) for interaction of phlegm and stasis; and Daheng (SP 15), Guanyuan (CV 4), Zhongji (CV 3), Qihai (CV 6) and Zhongwan (CV 12) for retention of damp and heat.

Six patterns/syndromes are involved in clinical practice. In terms of the properties, functions and indications, the supplementary acupoints are selected on the basis of the core acupoints for different patterns/sydnromes of the disease.

Electroacupuncture at different intensities inhibits nociceptive discharges of wide dynamic range neurons in spinal dorsal horn of rats. / ä¸åŒå¼ºåº¦ç”µé’ˆå¯¹å¤§é¼ è„Šé«“èƒŒè§’å¹¿åŠ¨åŠ›ç¥žç»å ƒä¼¤å®³æ€§æ”¾ç”µçš„æŠ‘åˆ¶ä½œç”¨.

OBJECTIVES: To observe the effect of electroacupuncture (EA) at different intensities on nociceptive discharges of wide dynamic range (WDR) neurons in the spinal dorsal horns (DHs) of rats, so as to explore its regulatory characteristics on nociceptive signals at the spinal level. METHODS: A total of 25 male SD rats were used in the present study. A microelectrode array was used to record the discharge activity of WDR neurons in the lumbar spinal DHs of normal rats. After finding the WDR neuron, electrical stimulation (pulse width of 2 ms) was administered to the plantar receptive field (RF) for determining its response component of discharges according to the latency of action potential generation (Aß ï¼»0 to 20 msï¼½, Aδ ï¼»20 to 90 msï¼½, C ï¼»90 to 500 msï¼½ and post-discharge ï¼»500 to 800 msï¼½). High-intensity electrical stimulation was continuously applied to the RF at the paw's plantar surface to induce DHs neuronal windup response. Subsequently, EA stimulation at different intensities (1 mA and 2 mA) was applied to the left "Zusanli"(ST36) at a frequency of 2 Hz/15 Hz for 10 min. The induction of WDR neuronal windup was then repeated under the same conditions. The quantity of nociceptive discharge components and the windup response of WDR neurons before and after EA stimulations at different intensities were compared. RESULTS: Compared to pre-EA, both EA1 mA and EA2 mA significantly reduced the number of Aδ and C component discharges of WDR neurons during stimulation, as well as post-discharge (P<0.01, P<0.001). The inhibitory rate of C component by EA2 mA was significantly higher than that by EA1 mA (P<0.05). Meanwhile, both EA1 mA and EA2 mA attenuated the windup response of WDR neurons (P<0.05, P<0.01), and the effect of EA2 mA was stronger than that of EA1 mA (P<0.05). Further analysis showed that when EA1 mA and EA2 mA respectively applied to both non-receptive field (non-RF) and RF, a significant reduction in the number of Aδ component, C component and post-discharge was observed (P<0.05, P<0.01). EA2 mA at the non-RF and RF demonstrated a significant inhibitory effect on the windup response of WDR neurons (P<0.01, P<0.05), but EA1 mA only at the non-RF showed a significant inhibitory effect on the windup response (P<0.01). CONCLUSIONS: EA can suppress nociceptive discharges of spinal DHs WDR neurons in rats. The inhibitory impact of EA is strongly correlated with the location and intensity of EA stimulation, and EA2 mA has a stronger inhibitory effect than EA1 mA.

[Acupuncture theory in Huangdi Neijing and launching the natural history of body].

Chinese traditional medicine is long in the natural history, which focuses on herbal medicine, but has less discussion on acupuncture. On the basis of exploring the body knowledge in Huangdi Neijing (The Yellow Emperor 's Inner Canon) from the perspective of the natural history, especially through the investigation of the evolution of acupoint knowledge, the route of the natural history of body in Huangdi Neijing have been detected in the aspects of observation, record, nomination and classification. In Huangdi Neijing, the natural history of body is characterized by the object annotation, the interaction between the nature and things, and the practicability. Launching the natural history of body is of great significance to understanding the generation of classical body knowledge and constructing acupuncture theory.

[Exploring the treatment strategy of liver-regulating wood-softening acupuncture method for psoriasis vulgaris based on the theory of "liver as the thief of five organs"].

Inspired by the theory of "liver as the thief of five organs", the authors believe that although psoriasis vulgaris manifests externally, its root cause lies internally in liver disharmony. During the active and stable phases, conventional acupuncture combined with liver-regulating wood-softening acupuncture method is used to regulate blood and harmonize the liver, addressing both the symptoms and the root cause. During the remission phase, liver-regulating wood-softening acupuncture method is employed to soothe the liver and restrain the yin, while also regulating and nurturing the emotional state. This study provides a clinical approach to acupuncture treatment for psoriasis vulgaris.

OBJECTIVES: To observe the effect of electro-scalp acupuncture (ESA) on the expression of cytochrome P450a1/b1 (CYP27a1/b1), cytochrome P45024a (CYP24a), signal transducer and activator of transcription (STAT)4, STAT6, tumor necrosis factor-α (TNF-α), interleukin (IL)-1ß and IL-4 in ischemic cerebral cortex of rats with acute ischemic stroke, so as to explore its mechanism in alleviating inflammatory reaction of ischemic stroke. METHODS: Sixty SD rats were randomly divided into sham-operation, model, vitamin D3 and ESA groups, with 15 rats in each group. The middle cerebral artery occlusion rat model was established with thread ligation according to Zea-Longa's method. Rats in the vitamin D3 group were given 1, 25-VitD3 solution (3 ng·100 g-1·d-1) by gavage, once daily for 7 days. Rats in the ESA group were treated at bilateral anterior parietotemporal slash (MS6) with ESA (2 Hz/100 Hz, 1 mA), 30 min a day for 7 days. Before and after interventions, the neurological deficit score and neurobehavioral score were evaluated. TTC staining was used to detect the volume of cerebral infarction in rats. The positive expressions of CYP24a, CYP27a1 and CYP27b1 in the cerebral cortex of ischemic area were detected by immunofluorescence. The mRNA expressions of STAT4 and STAT6 in the cerebral cortex of ischemic area were detected by quantitative real-time PCR. The protein expression levels of TNF-α, IL-1ß and IL-4 in the cerebral cortex of ischemic area were detected by Western blot. RESULTS: Compared with the sham-operation group, the neurological deficit score, neurobehavioral score, the percentage of cerebral infarction volume, the positive expression level of CYP24a and mRNA expression level of STAT4, protein expression levels of TNF-α and IL-1ß in cerebral cortex were increased (P<0.01), while the positive expression levels of CYP27a1/b1 and STAT6 mRNA, protein expression level of IL-4 were decreased (P<0.01) in the model group. After the treatment and compared with the model group, the neurological deficit score, neurobehavioral score, the percentage of cerebral infarction volume, the positive expression level of CYP24a and mRNA expression level of STAT4, protein expression levels of TNF-α and IL-1ß in cerebral cortex were decreased (P<0.01), while the positive expression levels of CYP27a1/b1 and STAT6 mRNA expression level, protein expression level of IL-4 were increased (P<0.01) in the ESA and vitamin D3 groups. CONCLUSIONS: ESA can alleviate the inflammatory response in ischemic stroke, which maybe related to its function in regulating the balance between CYP27a1/b1 and CYP24a, converting vitamin D into active vitamin D3, inhibiting vitamin D3 degradation, and regulating Th1/Th2 balance.

OBJECTIVES: To observe the effect of electroacupuncture (EA) at "Neiguan" (PC6) on pain response in mice injected with complete Freund's adjuvant (CFA) in the hind paw, so as to investigate the mechanism of orexin 1 receptor (OX1R) -endogenous cannabinoid 1 receptor (CB1R) pathway in acupuncture analgesia. METHODS: A total of 48 male C57BL/6 mice were used in the present study. In the first part of this study, 18 mice were randomized into control, model and EA groups, with 6 mice in each group. In the second part of this study, 30 mice were randomized into control, model, EA, EA+Naloxone, EA+OX1R antagonist (SB33486) groups, with 6 mice in each group. Inflammatory pain model was established by subcutaneous injection of 20 µL CFA solution in the left hind paw. EA (2 Hz, 2 mA ) was applied to bilateral PC6 for 20 min, once a day for 5 consecutive days. The mice in the EA+Naloxone and EA+SB33486 groups were intraperitoneally injected with naloxone (10 mg/kg) or SB33486 (15 mg/kg) 15 min before EA intervention on day 5, respectively. Tail-flick method and Von Frey method were used to detect the thermal pain threshold and mechanical pain threshold of mice. Quantitative real-time PCR was used to detect the expression level of ß-endorphin mRNA in periaqueductal gray (PAG) of mice. The expression of OX1R positive cells in the lateral hypothalamic area (LH) and CB1R positive cells in the ventrolateral periaqueductal gray (vlPAG) were detected by immunofluorescence. RESULTS: Compared with the control group, the thermal pain threshold and mechanical pain threshold of the model group were decreased (P<0.001), the expression level of ß-endorphin mRNA in PAG was decreased (P<0.001), and the numbers of OX1R positive cells in LH and CB1R positive cells in vlPAG were decreased (P<0.05, P<0.001). Compared with the model group, the thermal pain threshold and mechanical pain threshold of the EA group were significantly increased (P<0.001), and the numbers of OX1R positive cells in LH and CB1R positive cells in vlPAG were increased (P<0.01, P<0.001). Compared with the EA group, the mechanical pain threshold in the EA+SB33486 group was significantly decreased (P<0.01), but there was no significant difference in the mechanical pain threshold between the EA+Naloxone group and EA group, and the numbers of OX1R positive neurons in LH and CB1R positive neurons in vlPAG were decreased in the EA+SB33486 group (P<0.001). CONCLUSIONS: EA at PC6 can achieve analgesic effect on CFA mice by activating the OX1R-CB1R pathway in the brain, and this effect is opioid-independent.

Acupuncture at "Die E acupoint" alleviates inflammatory reaction via inhibiting TLR4/MyD88/NF-κB signaling in rats with allergic rhinitis. / 基于Tollæ ·å—ä½“4/é«“æ ·åˆ†åŒ–å› å­88/æ ¸è½¬å½•å› å­κB信号通路探讨针刺"è¶è ­ç©´"æ”¹å–„å˜åº”æ€§é¼»ç‚Žå¤§é¼ å ç–«ç‚Žæ€§ååº”çš„æœºåˆ¶.

OBJECTIVES: To observe effects of acupuncture at "Die E acupoint" on the protein expression levels of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), nuclear transcription factor κB (NF-κB), transcription factor T-bet (T-bet), and GATA-binding protein-3 (GATA-3) in the nasal mucosa and the serum contents of related inflammatory cytokines in rats with allergic rhinitis, so as to explore the mechanism of acupuncture in treating allergic rhinitis. METHODS: Twenty-four healthy SD rats were randomly divided into blank, model, acupuncture, and sham acupuncture groups, with 6 rats in each group. The rat model of allergic rhinitis was established by using ovalbumin induction. The rats in the acupuncture group received bilateral acupuncture at the "Die E acupoint" with a depth of 15-20 mm, while the rats in the sham acupuncture group received only sham acupuncture (light and shallow acupunture of the skin at the "Die E acupoint" ). Both interventions were performed once daily for a total of 6 days. Behavioral scores of rats in each group were recorded. Pathological changes of nasal mucosa were observed by H.E. staining. Serum contents of IgE, ovalbumin-specific IgE (OVA-sIgE), interferon(IFN)-γ, interleukin(IL)-4, IL-10 and IL-17 were measured by ELISA and the protein expression levels of T-bet, GATA-3, TLR4, MyD88 and NF-κB p65 in the nasal mucosa were detected by Western blot. RESULTS: After modeling, compared with the blank group, rats in the model group showed increased behavioral scores, serum IgE, OVA-sIgE, IL-4, and IL-17 contents, and nasal mucosal GATA-3, TLR4, MyD88, and NF-κB p65 protein expression levels (P<0.05), whereas the contents of serum IFN-γ, IL-10 and the protein expression level of T-bet in the nasal mucosa were decreased (P<0.05). Comparison between the EA and model groups showed that acupuncture intervention can decrease the behavioral scores of rats with allergic rhinitis, the contents of serum IgE, OVA-sIgE, IL-4, IL-17, and the protein expression levels of GATA-3, TLR4, MyD88, and NF-κB p65 in the nasal mucosa (P<0.05), and up-regulate the contents of serum IFN-γ, IL-10, and the nasal mucosal T-bet protein expression level. Sham acupuncture did not have a significant modulating effect on the above indicators. Inflammatory infiltration of nasal mucosa was seen in the model group and sham acupuncture, and the inflammatory reaction was milder in the acupuncture group. CONCLUSIONS: Acupuncture at "Die E acupoint" can alleviate the symptoms of allergic rhinitis and suppress the inflammation of nasal mucosa in rats, which may be related to inhibiting the TLR4/MyD88/NF-κB signaling and balancing the levels of cytokines of Th1/Th2 and Treg/Th17, and T-bet/GATA-3.
