[Effect of Lingnan Chen's acupuncture on postmenopausal osteoporosis and serum GH and IGF-1].

OBJECTIVE: To compare the therapeutic effect on postmenopausal osteoporosis (PMOP) between Lingnan Chen's needling technique and calcitriol soft capsules and investigate the effect mechanism in view of serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1). METHODS: Seventy patients of PMOP were randomized into an observation group (35 cases, 4 cases dropped off ) and a control group (35 cases, 3 cases dropped off ). The patients of both groups were treated with calcium carbonate D3 tablets orally (600 mg each time, once daily). In the observation group, acupuncture was delivered at Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4), Sanyinjiao (SP 6), etc. with the specific reinforcing-reducing technique and qi-conducting technique of Lingnan Chen's acupuncture, once every two days, three times a week. In the control group, calcitriol soft capsules were taken orally, 0.25 µg each time, twice a day. The intervention measures of two groups all lasted 12 weeks. Before and after treatment, the bone mineral density (BMD), the levels of serum GH and IGF-1 were assessed in two groups. Before treatment and 4, 8 and 12 weeks after treatment, TCM symptoms score and the MOS item short form health survey (SF-36) score were evaluated and the therapeutic effects were compared between groups. RESULTS: In both within-group and between-group comparisons, the difference in BMD was not significant before and after treatment (P>0.05). After treatment, the levels of serum GH and IGF-1 were increased in the observation group (P<0.05), and higher than the control group (P<0.05). After 4, 8 and 12 weeks of treatment, the scores of TCM symptoms were reduced in both groups compared with those before treatment (P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). After 4, 8 and 12 weeks of treatment, except the score of general health 4 weeks after treatment in the control group, the scores of the other domains in SF-36 were increased in both groups compared with those before treatment (P<0.05). After 12 weeks of treatment, except the score for the general health and social functions, the scores of the other domains of SF-36 in the observation group were all higher than those in the control group (P<0.05). The total effective rate was 83.9% (26/31) in the observation group, higher than 59.4% (19/32) in the control group (P<0.05). CONCLUSION: Lingnan Chen's needling technique is effective on postmenopausal osteoporosis. This therapy may relieve the symptoms of osteoporosis and improve the quality of life, better than calcitriol soft capsules, and the effect mechanism may be related to the up-regulation of serum GH and IGF-1 in the patients.

Comparison of Efficacy between Acupuncture Therapies in Improving Sacroiliac Joint Malposition: A Systematic Review and Meta-Analysis.

AIM: To provide available quantitative evidence of efficacy and safety of acupuncture treatments for improving sacroiliac joint malposition. METHODS: Databases such as the China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (CQVIP), Wanfang Database (Wanfang), China Biology Medicine disc (CBMdisc), PubMed, Web of Science, EMBASE, and Cochrane Library were searched by computer to collect the reports on acupuncture treatment of sacroiliac joint malposition from the database creation to July 20, 2021. The selection of included studies, data extraction and coding, and bias risk assessment were conducted independently by two reviewers. RevMan5.4 software was used for meta-analysis, and the results were expressed as mean difference (MD) or standardized mean difference (SMD), with a confidence interval (CI) of 95%. RESULTS: A total of 10 randomized controlled clinical trials (RCTs) with 1019 participants were included. Their overall quality of methodology was not high, and there may be publication bias. Meta-analysis showed that the total effective rate of the treatment group was higher than that of the control group (OR = 2.74, 95% CI 2.00 to 3.74, P < 0.00001). The treatment group was better than the control group in improving VAS score (WMD = -1.56, 95% CI -2.18 to -0.94, P < 0.00001). The ODI score of the treatment group was lower than that of the control group (WMD = -6.04, 95% CI -7.05 to -5.02, P < 0.00001). With the improvement of the JOA score, the difference of iliac transverse diameter of sacroiliac joint dislocation and the index of sacroiliac joint malposition in the treatment group were better than those in the control group (P < 0.05). There was no significant heterogeneity among the studies. CONCLUSION: Acupuncture may have therapeutic advantages in improving sacroiliac joint malposition. Acupuncture and acupotomy provide a safe way to improve the related clinical symptoms and functional disorders in activity of sacroiliac joint dislocation. However, due to the low quality of the included literature, this conclusion still needs to be further verified by more high-quality and large-sample RCTs.

Efficacy of Bloodletting Therapy in Patients with Chronic Idiopathic Urticaria: A Randomized Control Trial.

OBJECTIVE: To assess the efficacy of bloodletting therapy (acupoint pricking and cupping) in patients with chronic idiopathic urticaria (CIU) in a randomized, control, parallel-group trial. METHODS: A total of 174 patients with CIU enrolled from March 2018 to October 2019 were randomized into three groups: group A treated with bloodletting therapy and ebastine, group B treated with placebo treatment (acupoint pseudopricking and cupping) and ebastine, and group C treated with ebastine only. The intention-to-treat analysis was conducted, and the primary outcome was the effective rate of UAS7 score being reduced to 7 or below after treatment phase. RESULTS: The effective rates at the end of treatment phase were different among the three groups (P < 0.05), which were 73.7% in group A, 45.6% in group B, and 42.9% in group C. Multiple analysis indicated differences between groups A and B (P < 0.0125) and groups A and C (P < 0.0125) and no difference between groups B and C (P > 0.0125). No severe bloodletting therapy-related adverse events were observed. CONCLUSIONS: In this study on patients with CIU, one month of bloodletting therapy combined with ebastine is clinically beneficial compared with placebo treatment combined with ebastine and treatment with ebastine only. Thus, bloodletting therapy can be an effective complementary treatment in CIU. This trial is registered with ChiCTR1800015294.

[Protocol optimization and quality control of large-scale acupuncture clinical trial for infertility].

The design of research protocol and quality control are the key to ensure the quality of clinical trial. A randomized clinical trial regarding the effects of medication combined with acupuncture on live birth rate in polycystic ovary syndrome (PCOS), which was initially designed as a comparative effectiveness research, then added with an acupuncture control group and finally became a factorial analysis, is taken as an example to explain the protocol design and optimization process, demonstrating the high level of methodology design and international recognization. By a series of measurements, such as unified purchase of acupuncture equipment, multiple trainings and assessments for acupuncturists' knowledge and operation standardization, in-site supervision of local center experts, the standard operation of acupuncture could be ensured and the credibility and scientificity of research results could be improved.

Effect of Acupuncture and Clomiphene in Chinese Women With Polycystic Ovary Syndrome: A Randomized Clinical Trial.

Importance: Acupuncture is used to induce ovulation in some women with polycystic ovary syndrome, without supporting clinical evidence. Objective: To assess whether active acupuncture, either alone or combined with clomiphene, increases the likelihood of live births among women with polycystic ovary syndrome. Design, Setting, and Participants: A double-blind (clomiphene vs placebo), single-blind (active vs control acupuncture) factorial trial was conducted at 21 sites (27 hospitals) in mainland China between July 6, 2012, and November 18, 2014, with 10 months of pregnancy follow-up until October 7, 2015. Chinese women with polycystic ovary syndrome were randomized in a 1:1:1:1 ratio to 4 groups. Interventions: Active or control acupuncture administered twice a week for 30 minutes per treatment and clomiphene or placebo administered for 5 days per cycle, for up to 4 cycles. The active acupuncture group received deep needle insertion with combined manual and low-frequency electrical stimulation; the control acupuncture group received superficial needle insertion, no manual stimulation, and mock electricity. Main Outcomes and Measures: The primary outcome was live birth. Secondary outcomes included adverse events. Results: Among the 1000 randomized women (mean [SD] age, 27.9 [3.3] years; mean [SD] body mass index, 24.2 [4.3]), 250 were randomized to each group; a total of 926 women (92.6%) completed the trial. Live births occurred in 69 of 235 women (29.4%) in the active acupuncture plus clomiphene group, 66 of 236 (28.0%) in the control acupuncture plus clomiphene group, 31 of 223 (13.9%) in the active acupuncture plus placebo group, and 39 of 232 (16.8%) in the control acupuncture plus placebo group. There was no significant interaction between active acupuncture and clomiphene (P = .39), so main effects were evaluated. The live birth rate was significantly higher in the women treated with clomiphene than with placebo (135 of 471 [28.7%] vs 70 of 455 [15.4%], respectively; difference, 13.3%; 95% CI, 8.0% to 18.5%) and not significantly different between women treated with active vs control acupuncture (100 of 458 [21.8%] vs 105 of 468 [22.4%], respectively; difference, -0.6%; 95% CI, -5.9% to 4.7%). Diarrhea and bruising were more common in patients receiving active acupuncture than control acupuncture (diarrhea: 25 of 500 [5.0%] vs 8 of 500 [1.6%], respectively; difference, 3.4%; 95% CI, 1.2% to 5.6%; bruising: 37 of 500 [7.4%] vs 9 of 500 [1.8%], respectively; difference, 5.6%; 95% CI, 3.0% to 8.2%). Conclusions and Relevance: Among Chinese women with polycystic ovary syndrome, the use of acupuncture with or without clomiphene, compared with control acupuncture and placebo, did not increase live births. This finding does not support acupuncture as an infertility treatment in such women. Trial Registration: clinicaltrials.gov Identifier: NCT01573858.

Study of acupuncture for low back pain in recent 20 years: a bibliometric analysis via CiteSpace.

BACKGROUND: Acupuncture has been applied to relieve low back pain (LBP) in many countries. However, a bibliometric analysis of the global use of acupuncture for LBP is rare. OBJECTIVE: The aim of this study was to demonstrate the state of the art and trends concerning the global use of acupuncture for LBP in recent 20 years. METHODS: Literature relating to acupuncture for LBP from 1997 to 2016 was retrieved from Web of Science. CiteSpace was used to analyze country/institution, cited journals, authors/cited authors, cited references, and keywords. An analysis of counts and centrality was used to reveal publication outputs, countries/institutions, core journals, active authors, foundation references, hot topics, and frontiers. RESULTS: A total of 958 references were obtained, and the total number of publications continually increased over the investigated period. Journal articles (662) were the most frequently occurring document type. The most productive country and institution in this field was the USA (342) and Harvard University (47), respectively. The J Altern Complem Med (69) was the most productive journal, and Pain (636) was the most cocited journal, which reflected the nature of the research. The Haake's (2007) article (cocitation counts: 130) and the Cherkin's (2001) article (centrality: 0.59) were the most representative and symbolic references, with the highest cocitation number and centrality, respectively. Cherkin was the most influential author, with the highest number of publications of 25 and a cocitation number of 226. The four hot topics in acupuncture for LBP were research method, evaluation, economy, and comprehensive therapy. The three frontier topics were intervention, test reliability, and prevalence. CONCLUSION: This study provides an insight into acupuncture for LBP and valuable information for acupuncture researchers to identify new perspectives on potential collaborators and cooperative institutions, hot topics, and research frontiers.

Immunolocalization of Jian Carp (Cyprinus Carpio Var. Jian) Cathepsin B: Cloning, Expression, Characterization, and Antibody Preparation.

Cathepsin B (CatB) cDNA of 759 bp from Jian carp (Cyprinus carpio var. Jian) with amino acid similarity of 99.6% to common carp was cloned. The mature CatB was expressed in Escherichia coli BL21 transferred with vector CatB-pET-30a. It was purified and identified as a single band (29 kDa) on SDS-PAGE. Optimum CatB activity was observed at 40 °C and pH 5.5. Mouse anti-CatB polyclonal antibody with a high titer of 1:256000 was prepared successfully and shown to specifically recognize the antigen both in prokaryotic cells and in the tissues of Jian carp according to western blotting and immunohistochemistry results. Immunolocation analysis showed that CatB distribution at protein level varied among the tested tissues. The results presented in this study may provide a significant reference for future research on the inherent relationship between CatB and the quality of fish or fish products at both the gene and protein levels.

[Flying needling therapy combined with clomiphene for ovulation failure in polycystic ovary syndrome:a randomized controlled trial].

OBJECTIVE: To compare the efficacy among the combined treatment of flying needling therapy and clomiphene, the simple application of flying needling therapy and simple clomiphene in the treatment of ovulation failure in polycystic ovary syndrome (PCOS). METHODS: Ninety patients of PCOS were randomized into a flying needling therapy group, a medication group and a combined treatment group, 30 cases in each one. In the flying needling therapy group, the flying needling therapy was simply applied to Ganshu (BL 18), Shenshu (BL 23), Zhongwan (CV 12), Shuifen (CV 9), Guanyuan (CV 4) and Zhongji (CV 3). The unilateral back-shu points were used alternatively in each treatment. The needles were inserted rapidly with rotation technique and even-needling manipulation. The needles were retained for 30 min. The treatment was given once every two days, 3 times a week. In the medication group, clomiphene was taken orally on the 5th day of menstruation, continuously for 5 days. In the combined treatment group, the flying needling therapy and clomiphene were used in combination. All of the patients were treated for 3 months and followed up for 1 month. The ovulation rates were compared among the three groups. The levels of androgen testosterone were compared before and after treatment. RESULTS: In the combined treatment group, the ovulation rate was 86.2% (100/116), better than 66.7% (80/120) in the flying needling therapy group and 69.6% (78/112) in the medication group (both P<0.05). The efficacy was similar between the fly needling therapy group and the medication group (P>0.05). After treatment, the level of testosterone was reduced in the three groups (all P<0.05). In the combined treatment group, the improvement in androgen level was better than those in the flying needling therapy group and the medication group (both P<0.05). The efficacy was similar between the flying needling therapy group and the medication group (P>0.05). The adverse reactions in the combined treatment group and the flying needling therapy group were lower than those in the medication group (both P<0.05). CONCLUSIONS: The flying needling therapy effectively improves in the ovulation failure of PCOS and its effect is similar to clomiphene. The allied treatment of them apparently improves the clinical efficacy and alleviates the adverse reactions.

Study of Evodia hot compress plus electro-acupuncture in patients who have undergone abdominal surgery.

BACKGROUND: The importance of postoperative gastrointestinal function recovery is being increasingly recognized. In this multi-center randomized controlled study, we evaluated the efficacy and safety of Evodia hot compress (ECS) plus electro-acupuncture (EA) for patients who developed postoperative gastrointestinal tract dysfunction after abdominal surgery. METHODS: 1009 patients who developed postoperative gastrointestinal tract dysfunction after abdominal surgery were enrolled. All patients received conventional therapies for 7 days from the 1st postoperative day and were randomly assigned to receive coarse salt hot compress, Evodia hot compress or Evodia hot compress plus electro-acupuncture twice a day for 7 days. RESULTS: The mean time to first flatus and to first bowel sounds was comparable among the four groups (P>0.05). The control group had a significantly shorter time to defecation compared with patients receiving coarse salt hot compress, Evodia hot compress or Evodia hot compress plus electro-acupuncture (P<0.05). In patients undergoing open hepatectomy, the time to first defecation was the shortest in those who received Evodia hot compress plus electro-acupuncture (89.3±25.5 h), which was significantly different from that of controls(134±31.1 h), those who received coarse salt hot compress (106.7±36.4 h) and those who received Evodia hot compress (109.9±42.1 h) (P<0.05) in patients undergoingopen cholecystectomy, the time to first defecation was the shortest in those who received Evodia hot compress (73.1± 24.7), which was significantly different from that of controls (77.8±29.7), those who received coarse salt hot compress 90.5±30.2) and those who received Evodia hot compress plus electro-acupunctur (83.9±34.0). CONCLUSION: Evodia hot compress plus electro-acupuncture confers benefit in postoperative recovery of gastrointestinal function of patients who have undergone abdominal surgery and it is overall safe to use.

Combination of flying needle with Chinese Herbal Medicine in the treatment of Atopic dermatitis: A clinical trial.

Atopic dermatitis (Atopic dermatitis, AD) is a kind of chronic recurrent dermatitis. So far, no curative treatment has been found yet. Acupuncture, as a kind of alternative medicine, Flying Needle is a kind of acupuncture, which has a unique curative effectiveness in improving the skin lesion and itch. A single-center, prospective, randomized clinical design was conducted. The curative effect of the combination of Chinese herbal medicine and acupuncture for the treatment of Atopic dermatitis was assessed. Thirty (30) patients were treated with Flying Needle and Chinese herbal medicine. Because of personal reasons, one (1) dropped out. The patients accepted Flying Needle treatment 3 times a week and the internal medicine 3 times daily for in all 12 weeks. Before treatment, and after treat 4,8 and 12 weeks, assessments were performed. After treat 12 weeks, all patients of SCORAD score were dropped, with the mean SCORAD score declining to 19.58 ± 12.21. The recovery and removal rate comparison (*δx² = 5.28, P= 0.03<0.05). There are no side effects. The results hint that combine Flying Needle with Chinese herbal medicine are benefit on patients with atopic dermatitis and the effectiveness may better than oral medicine alone.

Antioxidant activities and phenolics of fermented Bletilla formosana with eight plant pathogen fungi.

The tubers of Bletilla formosana were fermented with eight plant pathogen fungi, respectively, and antioxidant activities and total phenolic content (TPC) of the crude extracts of fermented products and non-fermented products were investigated. The antioxidant activities were evaluated in three different test systems [DPPH, ABTS radical-scavenging activity, and ferric reducing-antioxidant power (FRAP)]. It was found that the extract of Helminthosporium maydis fermented B. formosana (FBF) possessed the highest TPC and exhibited a significant antioxidant activity compared with non-fermented product and other fermented products. Correlation analysis between antioxidant activities and TPC was also investigated. The good correlation between antioxidant activities and TPC revealed that the phenolic compounds might be the major contributors for the high antioxidant activities of the fermented B. formosana. Two phenolic compounds, curvularin and dehydrocurvularin, were isolated from H. maydis FBF, which had never been reported from plant of orchidaceae or H. maydis. Curvularin exhibited significant antioxidant activities, and was also present at a high concentration (0.373 mg/mg extract sample), implying an important role for the antioxidant activity of H. maydis FBF. This study suggested that proper fermentation processing could improve TPC and antioxidant activities of B. formosana.

[Sleep disorder treated mainly with flying needling therapy: a clinical randomized controlled research].

OBJECTIVE: To observe the clinical efficacy on sleep disorder in the intervention of flying needling therapy and compare the efficacy difference among flying needling therapy, estazolam and non-acupoint acupuncture. METHODS: Three hundred and fifteen cases of sleep disorder were randomized into a flying needling group (110 cases), an estazolam group (107 cases) and a non-acupoint acupuncture group (98 cases). In the flying needling group, the flying needling therapy was applied to Sanyinjiao (SP 6), Anmian (EX HN22), Shenmen (HT 7) and so on. Additionally, vitamin B1 was prescribed for oral administration and the intradermal needle method was given at the Back-shu points. In the estazolam group, estazolam was prescribed for oral administration. Also the non-acupoint acupuncture and the acupoint sticking therapy on the Back-shu points were given additionally. In the non-acupoint acupuncture group, the non-acupoint acupuncture, oral administration of vitamin B1 and the acupoint sticking therapy on the Back-shu points were applied. The treatment of 2 weeks were required in all the groups. The efficacy and the score of PSQI (Pittsburgh sleep quality index) were observed in the 2-week follow-up visit. RESULTS: The total effective rate in the flying needling group was 84.1% (90/107), which was superior to 59.7% (62/104) in the estazolam group and 25.0% (24/96) in the non-acupoint acupuncture group (both P < 0.05). In the follow-up observation, the score of each item and the total score of PSQI were lower apparently than those before treatment in each group (all P < 0.05), and those in the flying needling group were lower apparently than those in the other two groups (all P < 0.05). CONCLUSION: The flying needling therapy as the chief therapeutic method effectively improves the sleep quality for the patients with sleep disorder, which is apparently superior to estazolam and non-acupoint acupuncture.

[Correlation and path analysis on agronomic traits of Gentiana rigescens].

OBJECTIVE: The interrelation of yield and agronomic traits of Gentiana rigescens was studied for the germplasm and breeding variety of this species. METHOD: Twelve agronomic traits, root diameter, root length, root number, root biomass, stem diameter, plant height, the first branch number, leaf length, leaf width, leaf length/leaf width ratio, calyx length, and calyx number of G. rigescens from 26 wild populations in Yunnan were determined for correlation analysis, multiple stepwise regression analysis and path analysis. RESULT: Correlation analysis showed that there were significantly positive correlation between the traits of aboveground part and the length, diameter, number, and biomass of the root. Multiple stepwise regression analysis showed that length, width, and number of root, plant height, the first branch number, and the calyx number were the main factors that affected the root biomass. Path analysis showed that the diameter, length, and number of the root, the stem height, and the first branch number had a direct positive effect on the root biomass. CONCLUSION: The traits, such as high and strong stem, high number of first branch number and shrubby shape could be selected for the breeding and high yielding of G. rigescens.

OBJECTIVE: To find out an effective therapy for Parkinson's disease. METHODS: Sixty cases were randomly divided into an abdominal acupuncture group and a control group, 30 cases in each group. The abdominal acupuncture group were treated with Madopa and abdominal acupuncture at Zhongwan (CV 12), Xiawan (CV 10), Qi-hai (CV 6) and Guanyuan (CV 4), etc. ; and the control group were treated with Madopa. RESULTS: After treatment of 3 courses, the effective rate was 90.0% in the abdominal acupuncture group and 83.3% in the control group with a significant difference between the two groups (P<0.05). CONCLUSION: Abdominal acupuncture combined with Madopa can elevate therapeutic effect of Madopa and reduce adverse effects of Madopa for the patient of primary Parkinson's disease.

[Studies on the shade-endurance capacity of Glycyrrhiza uralensis].

OBJECTIVE: To study the shade-endurance property of Glycyrrhiza uralensis and provide rationale for the practice of inter-cropping G. uralensis with trees. METHOD: Black shading nets were used to provide five different environments of light intensities (light penetration rates of 100%, 75%, 65%, 50% and 25%, respectively). To assess the shade-endurance capacity of G. uralensis, several aspects were evaluated, including growth characters, physiological and ecological characters, biomass, and chemical contents. RESULT AND CONCLUSION: G. uralensis is a light-favored plant. The growth indices such as plant height, stem diameter, leaves number, root diameter, biomass, and daily average photosynthetic rate (Pn) are highest when light permeation rate is 100%. All these indices decrease when light intensity decreases. However, G. uralensis possesses shade-endurance capacity to some degree; it adapts to the shading environment by increasing the leaf area and chlorophyll contents. Shading has no obvious effect on the absolute light energy utilization rate (Eu) or Fv/Fm ratio. The influence of shading on the chemical contents of G. uralensis is obvious.
