To select the most effective parameters of electroacupuncture (EA) at Hegu (LI4) and Sanyinjiao (SP6), a traditional acupuncture formula that induces labor, by comparing its effects on uterine contraction in late-stage pregnant rats, so as to improve the effects of acupuncture on induction of labor and its clinical maneuverability and provide the basis for further mechanism research.

From ancient times to the present,acupuncture has made tremendous contributions to women' s reproductive health.Based on traditional Chinese medicine of kidney-menstruation-Chong and Ren-uterus axis and Western medicine of hypothalamus-pituitary-ovarian axis comparative analysis study,try to explore possible ways from the acupuncture point to molecular changes in the process of acupuncture and moxibustion treatment.

ObjectiveTo explore the relation between the uterine position and acupoint effect by analyzing the data of a clinical trial of electroacupuncture in treating primary dysmenorrhea.MethodThe uterine position was detected by ultrasonic examination;Visual Analogue Scale (VAS) was used to evaluate the pain degree before and after intervention; Retrospective Symptom Scale (RSS) was adopted to determine the improvement of symptoms.ResultThere were no significant differences in comparing the VAS score, real-time effect and post-treatment effect, and effective rate among different uterine positions (P>0.05). Electroacupuncture at Sanyinjiao (SP 6) can produce a real-time effect in releasing abdominal pain and relevant symptoms of dysmenorrhea in patients with anteversion of uterus, a less significant effect was shown in patients with retroposition of uterus, while no effect was shown in patients with uterus at middle position.ConclusionElectroacupuncture at Sanyinjiao possibly has a specific effect in releasing abdominal pain and relevant symptoms of dysmenorrhea at anteversion of uterus, and the uterine position may be related to the corresponding meridians and Zang-fu organs. The current statistical result indicates that there is no relation between the uterine position and the effect of Sanyinjiao, but this conclusion still needs proving by prospective randomized controlled clinicaltrials.

Background: Nummular eczema (NE) is an inflammatory skin disease characterized by pruritic coin-shaped lesions and a long-lasting and easy-relapsing course, which severely decreases patients' qual-ity of life. This case was designed to observe the effects of specific acupuncture techniques on pruritic NE management.Case presentation: A 22-year-old female was first diagnosed with pruritic NE three years earlier. No al-lergies were found in the patch test;while emotional stress would trigger and aggravate the NE. External application of 0.1％tacrolimus failed to reverse this condition over a long period of treatment. Treatment&outcomes: An individualized acupuncture treatment protocol was identified. Half needling and encircling needling were applied at local eczematous lesions, with routine needling at meridian points, once per week, for 12 treatment sessions. All outcome measures, including the Eczema Area and Severity Index, Visual Analogue Scale score for pruritus, Self-Rating Anxiety Score, and Dermatology Quality Life Index, substantially improved over 6 months from pre-treatment to 3 months post-treatment. Conclusion: Acupuncture might be a promising non-pharmacological treatment method for patients with NE, especially for those with emotional stress. A randomized controlled trial with an adequate sample size and rigorous study design is required to verify the results of the study.

Objective To explore the application low of stimulation parameters of transcutaneous electrical acupoint stimulation(TEAS)and transcranial direct current stimulation(tDCS)for post-stroke movement disorders based on data mining.Methods The relevant clinical research literature was retrieved from CNKI,Wanfang Data,VIP,CBM,PubMed and Web of Science from January 2000 to May 2023.A database was set up after quality assessment.Frequency analysis,association rules and complex network analysis were used to explore the application law of core acupoints and electrical stimulation parameters.Results A total of 79 articles were included and 128 groups of data were contained.For TEAS,the core acupoints included Waiguan(TE5),Shousanli(LI10),Zusanli(ST36),Hegu(LI4),Neiguan(PC6),Yanglingquan(GB34),etc.,while the most commonly used acupoint combinations of upper limb and lower limb were Shousanli(LI10)-Waiguan(TE5)and Yanglingquan(GB34)-Zusanli(ST36).Among the electrical stimulation parameters of TEAS,the frequencies used vary widely,and 100 Hz was most commonly used,while 2 Hz TEAS was also mainly used for stimulating acupoints located on upper limbs in the treatment of flaccid paralysis.The application of other electrical stimulation parameters was relatively consistent.The bidirectional symmetrical square-wave with 200-250 μs pulse-width was used in majority of studies.The stimulus intensity was mostly determined by patient tolerance.For tDCS,stimulation electrodes were often positioned on the projection of the primary M1,and the safe stimulus intensity was mostly set as 1 to 2 mA.Conclusion In the treatment of post-stroke movement disorders,appropriate acupoints and electrical stimulation parameters of TEAS should be determined on the muscle strength and muscle tension of stroke patients at different stages after stroke,particularly the selection of electric stimulating frequency.

OBJECTIVETo analyze the relationship betweenand effect by data mining technique with retrieving clinical literature about acupuncturesince the founding of the country.

METHODSThe modern computerization and data mining technologies were adopted to set up clinical literature about acupuncturedatabase. The relevant clinical literature was collected, screened, extracted, and statistical and correlation analyses were used so as to explore the relationship betweenand effect.

RESULTS82.1% (46/56) of the studies considered thatwas related to the effect; 17.9% (10/56) of the studies considered thatwas unrelated to the effect. The support ofrelated to the effect is 100% on dysmenorrhea and facial paralysis. 72% (18/25) of the the articles of pain syndrome considered thatwas related to the effect; 28% (7/25)of the studies considered thatwas unrelated to the effect. In the research of the relationship between the features ofand effect, 60.7% of the studies suggested that the sense of conduction was positively correlated with the effect. There were 21 studies on the relationship between the intensity ofand effect, involving a variety of diseases, which was related to the type of the disease. 58.3% (7/12) of the articles on dysmenorrhea and 63% (34/54) on pain syndrome supported conduction positively correlated to effect, showing the highest frequencies. 50% (3/6) of the papers on facial paralysis supported weaksensation positively correlated to effect, which was the highest frequency.

CONCLUSIONSMost studies considered thatcan improve clinical efficacy. The relationship between different features ofand effect is closely related to the disease. Further study may focus on high quality research on the relationship betweenand the obvious effect achieved by acupuncture so as to summarize the law of.

This study was aimed to observe the clinical effect of low frequency negative pressure meridian viscera regulating sub-health.According to the diagnostic criteria,34 cases of sub healthy subjects were randomly selected.The low frequency negative pressure meridian viscera regulating method was used.By analyzing the cupping spot color feedback conditioning information of the sub healthy subjects and conditioning before and after the synthesis of the four diagnostic methods of digital and quantitative,its effect was evaluated.After 4 weeks of continuous adjustment,34 cases of sub healthy subjects,compared with preconditioning,cupping spot color of the subjects was shallow or disappeared (P ＜ 0.01);after adjusting,the proportion of light red tongue and thin white tongue coating increased obviously (P ＜ 0.05),the proportion of ecchymosis tongue was decreased compared to precoditioning (P ＜ 0.05);after adjustment,core symptoms such as back pain,neck pain,anxiety and irritability,were alleviated or disappeared;after adjustment,the pulse string tightness decreased significantly (P ＜ 0.01).It was concluded that the low frequency negative pressure meridian viscera regulation can significantly improve discomfort symptoms of sub healthy subjects and promote therecovery of tongue,pulse and cupping spot color in sub healthy subjects.This method is worth popularizing and further exploring.

Objective: To explore the analgesic effects and uterine hemodynamics of perpendicular needling (PN) and transverse needling (TN) at SP 6 in patients with primary dysmenorrhea (PD). Methods: In this randomized controlled trial, patients with PD diagnosed with cold-dampness con-gealing pattern were randomly assigned in a ratio of 1:1 to receive PN or TN at bilateral SP 6 for 10 min. Acupuncture was performed when the menstrual pain score was over 40 mm on the first day of menstruation, as measured using the visual analog scale for pain (VAS-P). The primary outcome was average menstrual pain (VAS-P). Secondary outcomes included the pulsatility index (PI), resistance index (RI), and systolic-diastolic peaks ratio (S/D) in uterine arteries as measured using color Doppler ultra-sonography;anxiety as assessed using the Hamilton Anxiety Rating Scale (HAMA), blood pressure (BP), and heart rate (HR). Results: Forty-eight patients completed the study. The TN group exhibited a significant reduction in VAS-P scores (-5.71 mm, 95％ confidence interval (CI): -8.78, -2.63, P = .001), RI values (-0.05, 95％ CI:-0.09,-0.01, P=.015), and HAMA values (-2.50, 95％CI:-4.78,-0.22, P=.032) when compared with the PN group. No significant differences in PI, S/D, BP, or HR values were observed between the two groups (P>.05). Conclusion: TN at SP 6 was superior to PN in alleviating menstrual pain and anxiety in patients with PD. This analgesic effect of TN may be due to its better ability to improve uterine arterial blood flow via decreases in RI values.

Objective:To explore characteristics of intestinal flora in patients with rheumatoid arthritis complicated with inter-stitial lung disease(RA-ILD),to analyze its influencing factors,and to explore improvement of intestinal flora in patients with RA-ILD by different treatment methods.Methods:A total of 100 patients with RA-ILD who visited Shijiazhuang People's Hospital from June 2021 to June 2022 were selected as research objects,and 100 healthy patients in Shijiazhuang People's Hospital during same pe-riod were selected as healthy group.High throughput sequencing was performed on intestinal flora of two groups,OTU flora abundance and α-Diversity,β-diversity,flora distribution and LEfSe difference were analyzed.Another 100 patients with RA-ILD were randomly divided into group A(n=50)and group B(n=50).Group A was treated with leflunomide+nidanib or pifenidone,and group B was treated with leflunomide+nidanib or pifenidone+bifidobacterium triad.Improvement of intestinal flora in two groups after treatment was analyzed.Correlation analysis was used to determine correlation between changes of intestinal flora and clinical characteristics and indicators in RA-ILD patients.Results:OTU flora abundance,α-diversity and β-diversity in RA-ILD patients were lower than that of healthy people.Abundance of Intestinibacter in RA-ILD group was higher than that in healthy group,and abundance of Lactobacillus,Escherichia coli,Klebsiella,Candidatus saccharimonas,Odoribacter and Enterococcus in RA-ILD group were lower than that in healthy group.After treatment,flora structure of group A and group B was improved.Group B was closer to healthy population,and cu-rative effect was significantly better than that of group A.Integinibacter bacteria level was positively correlated with age,RA course,DAS28,CRP,RF and KL-6(P<0.05),and negatively correlated with DLCO(P<0.05).Lactobacillus level was negatively correlated with course of RA,DAS28,CRP,RF,IL-6(P<0.05),and positively correlated with VC(P<0.05);Shigella coli level was negtively correlatied with RA course,ILD course,DAS28,ESR,RF,TNF-α(P<0.05).Klebsiella level was positively correlated with VC and DLCO(P<0.05);Bacterial level of Candida saccharimonas was negatively correlated with DAS28,ESR,CRP,RF,IL-6,TNF-α(P<0.05)and positive correlated with DLCO(P<0.05);Odoribacter bacteria level was negatively correlated with DAS28,CRP,RF,IL-6 and KL-6(P<0.05),and positively correlated with VC(P<0.05);Enterococcus level was negatively correlated with course of RA,ILD,DAS28,ESR,RF and KL-6(P<0.05),while positively correlated with DLCO(P<0.05).Conclusion:Intestinal microflora abundance of RA-ILD patients is significantly lower than that of healthy people,and there aree significant differences in some microflora,which are closely related to clinical characteristics and indicators.Using of bifidobacterium triad in clinical treatment is helpful to improve intestinal flora of RA-ILD patients.

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.
