OBJECTIVE: To observe the effects of catgut embedding and polyglycolic acid/poly-lactic acid (PGLA) embedding at "Zusanli" (ST 36) on the activation of local skin mast cells (MC), and expression of substance P (SP) and histamine (HA), and to explore the mechanism of the temporal stimulation effect of acupoint catgut embedding and provide a foundation for further research on the initiation mechanism of acupoint catgut embedding. METHODS: One hundred and sixty male SPF-grade SD rats were randomly divided into a blank group (10 rats), a sham-embedding group (50 rats), a catgut group (50 rats), and a PGLA group (50 rats). Each intervention group was further randomly divided into five subgroups according to the time points after intervention: 8 hours, 3 days, 7 days, 14 days, and 21 days, with 10 rats in each subgroup. One-time sham-embedding, catgut embedding and PGLA embedding was given at left "Zusanli" (ST 36) in each intervention group, respectively. The skin and subcutaneous connective tissue of the left "Zusanli" (ST 36) were collected at the corresponding time points after intervention, except for the blank group (only one day before intervention). Toluidine blue staining was used to detect MC count and degranulation, and immunohistochemical staining was used to detect the expression of SP and HA positive cells. RESULTS: There was no significant difference in MC count between the subgroups of each intervention group and the blank group (P>0.05). There was no significant difference in MC count between the subgroups of the catgut group and the PGLA group (P>0.05). The MC count in the 8-hour subgroup of PGLA group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the MC count in the 21-day subgroup of PGLA group was lower than that in the 21-day subgroup of catgut group (P<0.05). Compared with the blank group, the degranulation rates of MC were increased in the 8-hour and 3-day subgroups of sham-embedding group, 8-hour, 3-day, and 7-day subgroups of catgut group, and 8-hour, 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.01, P<0.05, P<0.001). There was no significant difference in the degranulation rate of MC between the subgroups of the catgut group and the PGLA group (P>0.05), and no significant difference in the degranulation rate of MC between the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of SP positive cells was increased in the 8-hour subgroup of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.001, P<0.05). The expression of SP positive cells in the 7-day subgroup of catgut group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.001). The expression of SP positive cells in the 7-day subgroup of PGLA group was higher than that in the 3-day subgroup of PGLA group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.01). There was no significant difference in the expression of SP positive cells between the subgroups of the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of HA positive cells was increased in the 8-hour, 3-day subgroups of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 8-hour, 3-day, 7-day, 14-day, and 21-day subgroups of PGLA group (P<0.001, P<0.01, P<0.05). The expression of HA positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.05), while the expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 8-hour subgroup of PGLA group (P<0.05), and the expression of HA positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.05). The expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 3-day subgroup of catgut group (P<0.05). CONCLUSION Catgut and PGLA embedding at "Zusanli" (ST 36) in healthy rats could induce changes in local skin MC, SP, and HA, which may be one of the mechanisms of the temporal stimulation effect after acupoint embedding. There are certain differences between different suture materials. A moderate inflammatory response in the acupoint area, mediated by MC and involving SP and HA, may be one of the initiating factors for the effect of acupoint catgut embedding.

OBJECTIVE: To explore the impacts on weight reduction effect treated with acupoint thread embedding therapy at different tissue levels under ultrasonic guidance. METHODS: A total of 70 patients with overweight or obesity were randomized into a shallow-tissue thread embedding group (35 cases, 5 cases dropped off) and a deep-tissue thread embedding group (35 cases, 4 cases dropped off). Under ultrasonic guidance, the thread was embedded in the shallow tissue level and the deep tissue level respectively. The acupoints were Zhongwan (CV 12), Xiawan (CV 10), Shuifen (CV 9), Zhongji (CV 3), etc. The thread embedding therapy was exerted once every 2 weeks, totally for 3 times. Before and 2 weeks after treatment, body mass, body mass index (BMI), waist circumference and hip circumference were recorded in the patients of the two groups separately. After each treatment, the number and the property of blood vessels under each acupoint were detected by ultrasound. Besides, the needling sensation and the intensity were scored and the adverse events were observed after thread embedding therapy. RESULTS: After treatment, the reduction range of body mass, BMI and waist circumference in the deep-tissue thread embedding group were larger than those in the shallow-tissue thread embedding group successively ( CONCLUSION The deep-tissue thread embedding therapy achieves the stronger

OBJECTIVE: To evaluate the safety of thread embedding acupuncture therapy (TEAT) and discuss the prevention and treatment of some adverse events (AEs). METHODS: Review of databases, including China National Knowledge Infrastructure (CNKI), CBMdisc, Wanfang, VIP databases and English literature published in PubMed, MEDLINE, EMBASE and Web of Science, were searched from their inception to January 2020, randomized controlled trials (RCTs) and case reports in which AEs with TEAT were included. Cochrane Collaboration's tool and RevMan V.5.3.3 software were used to evaluate the quality of the studies. RESULTS: A total of 61 studies (45 RCTs and 16 case reports) with 620 cases of AEs were included in this review. These studies were published in two countries: China and South Korea. Twenty eight kinds of AEs were summarized. The most common AEs were induration, bleeding and ecchymosis, redness and swelling, fever, and pain. They were accounted for 75.35% (425/564) in the review, and most of them were mild. The rarest AEs were epilepsy, irregular menstruation, skin ulcer, thread malabsorption, and fat liquefaction, with 1 case each. But not all of them had clear causal relationship with TEAT. Most of the AEs were local reactions [with incidence of 9.83% (480/4,882)] and systemic reactions accounted for only 1.27% (62/4,882). Although the included studies showed that AEs were very commonly encountered (11.09%), only 5 cases of severe AEs reported from 2013 to 2017 (0.1%) by using catgut thread, which are rarely seen nowdays with the wide use of new absorbable surgical suture. All of the severe AEs were recovered after symptomatic treatment with no sequelae. CONCLUSIONS The evidence showed that TEAT is a relatively safe and convenient therapy especially since application of new absorbable surgical suture. Improving practitioner skills, regulating operations, and paying attention to the patients' conditions may reduce the incidence of AEs and improve safety of TEAT.

OBJECTIVE: To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors. METHODS: Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography. RESULTS: Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05). CONCLUSION The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.

OBJECTIVE: To observe the effects of acupoint catgut embedding on miscarriage prevention and pregnancy outcome in patients with threatened abortion after in vitro fertilization-embryo transfer (IVF-ET). METHODS: Sixty cases of patients with threatened abortion after IVF-ET were randomly divided into an observation group and a control group, 30 cases in each group. The patients in the control group were treated with intramuscular injection of progesterone (40 mg) once every day, while the patients in the observation group, on the basis of the treatment of control group, were treated with catgut embedding at Geshu (BL 17), Ganshu (BL 18), Shenshu (BL 23), Pishu (BL 20), Weishu (BL 21), Xuehai (SP 10), Diji (SP 8) and Fuliu (KI 7), once every two weeks, six times as a course of treatment. The treatment was given until 12 weeks into pregnancy. The level of serum human chorionic gonadotropin (HCG), estradiol (E) and progesterone (P) before and after treatment was recorded; the TCM syndrome score before and after treatment was compared; the successful pregnancy rate and spontaneous abortion rate after treatment were observed in the two groups. RESULTS: Compared before treatment, the scores of TCM syndrome in both groups were reduced after treatment (both <0.01), and score in the observation group was superior to that in the control group (<0.05). After treatment, the clinical efficacy in the observation group was superior to that in the control group (<0.05). After treatment, the hormone levels (β-HCG, E, P) in both groups were increased steadily; the hormone levels in 6-week pregnancy, 8-week pregnancy and 10-week pregnancy were significantly higher than those in 4-week pregnancy (all <0.05); except the levels of P and β-HCG in 10-week pregnancy, the hormone levels in the observation group were superior to those in the control group (all <0.05). After treatment, the early abortion rate was 16.7% (5/30) in the observation group, which was lower than 33.3% (10/30) in the control group (<0.01); the pregnancy rate was 96.0% (24/25) in the observation group, which was higher than 80.0% (16/20) in the control group (<0.01). CONCLUSION Acupoint catgut embedding is effective for preventing threatened abortion, which could significantly reduce the spontaneous abortion rate, improve the pregnancy success rate, regulate hormone levels in patients after IVF-ET.

OBJECTIVE: To compare the clinical efficacy of acupoint catgut embedding and bupropion hydrochloride sustained-release tablets in the treatment of tobacco dependence. METHODS: A total of 100 patients with tobacco dependence who met the inclusion criteria were randomly divided into an acupoint catgut embedding group and a drug group, 50 cases in each group. In the acupoint catgut embedding group, acupoint catgut embedding was applied at Xinshu (BL 15), Shenmen (HT 7), Tianmei (Extra), Taichong (LR 3), the treatment was given once every 2 weeks for 4 times; The bupropion hydrochloride sustained-release tablets was orally administered in the drug group for 7 weeks, 150 mg each time, once a day for the first 3 days, twice daily from day 4 to day 7, and once a day after day 8. The Fagerström test for nicotine dependence (FTND) score before and after treatment, the 4th and 8th week smoking cessation rate, the continuous smoking cessation rate and efficacy, compliance rate and adverse reaction rate were compared in the two groups. RESULTS: A total of 100 patients were enrolled, and 97 patients completed the study (loss rate was 3%), including 49 cases in the acupoint catgut embedding group and 48 cases in the drug group. The FTND scores in the two groups were lower than those before treatment (both <0.05). There was no significant difference between the two groups after treatment (>0.05). At the 4th and the 8th week, the smoking cessation rate in the acupoint catgut embedding group was 40.8% (20/49) and 79.6% (39/49) respectively, the smoking cessation rate in the drug group was 41.7% (20/48) and 83.3% (40/48) respectively, the two groups were equally effective (both >0.05). The continuous smoking cessation rate in the acupoint embedding group was 40.8% (20/49), which was equivalent to 41.7% (20/48) in the drug group (>0.05). The rate of complete compliance in the acupoint embedding group was 61.2% (30/49), which was significantly better than 37.5% (18/48) in the drug group (<0.05). The adverse reaction rate in the acupoint catgut embedding group was 12.2% (6/49), which was significantly lower than 29.2% (16/48) in the drug group (<0.05). CONCLUSION Acupoint catgut embedding can effectively improve the symptoms of tobacco dependence after smoking cessation. Its curative effect is close to that of bupropion hydrochloride sustained-release tablets, and it has good clinical compliance and less adverse reactions.

OBJECTIVE: To explore the therapeutic effect and mechanism of acupoint catgut embedding for chloasma in premenopausal women with liver stagnation. METHODS: A total of 92 patients of chloasma in premenopausal women with liver stagnation were randomized into an observation group and a control group, 46 cases in each one.In the observation group, acupoint catgut embedding was applied at Ganshu (BL 18), Pishu (BL 20), Sanyinjiao (SP 6), also the surrounding acupuncture was performed at facial part, once a week. In the control group, vitamin C (200 mg per time, 3 times a day) and vitamin E (100 mg per time, once a day) were prescribed for oral administration. Both of the two groups were given treatment for 12 weeks. The score of chloasma area and severity index (MASI), the serum levels of follicular stimulating hormone (FSH), leuteinizing hormone (LH) and estradiol (E) before and after treatment were observed in the two groups, and the clinical effect of the two groups were compared after 3 months of treatment. RESULTS: Finally, 44 cases in the observation group and 43 cases in the control group completed the study. The effective rate in the observation group was 88.6% (39/44), which was higher than 55.8% (24/43) in the control group (<0.01). Compared before treatment, the MASI scores after treatment were reduced in the two groups (<0.01, <0.05), the MASI score in follow-up in the observation group was reduced as compared with after treatment (<0.01), and the MASI scores after treatment and in follow-up in the observation group were lower than the control group (<0.01). Compared before treatment, the levels of FSH and LH in follow-up were reduced (<0.01), there was no significant difference between before treatment and in follow-up in the level of E in the observation group (>0.05). There was no significant difference between before treatment and in follow-up in the levels of FSH, LH and E in the control group (>0.05). In follow-up, the levels of FSH and LH in the observation group were lower than the control group (<0.01, <0.05), there was no significant difference in the level of E between the two groups (>0.05). CONCLUSION Acupoint catgut embedding can improve the clinical symptoms of chloasma in premenopausal women with liver stagnation, the mechanism may be related to regulate the serum level of sex hormone to reduce high sensitivity of melanocytes to estrogen.
