ABSTRACT
OBJECTIVE@#To investigate autophagy-related mechanisms of electroacupuncture (EA) action in improving gastrointestinal motility in mice with functional constipation (FC).@*METHODS@#According to a random number table, the Kunming mice were divided into the normal control, FC and EA groups in Experiment I. The autophagy inhibitor 3-methyladenine (3-MA) was used to observe whether it antagonized the effects of EA in Experiment II. An FC model was established by diphenoxylate gavage. Then the mice were treated with EA stimulation at Tianshu (ST 25) and Shangjuxu (ST 37) acupoints. The first black stool defecation time, the number, weight, and water content of 8-h feces, and intestinal transit rate were used to assess intestinal transit. Colonic tissues underwent histopathological assessment, and the expressions of autophagy markers microtubule-associated protein 1 light chain 3 (LC3) and Beclin-1 were detected by immunohistochemical staining. The expressions of phosphoinositide 3-kinases (PI3K)-protein kinase B (AKT)-mammalian target of rapamycin (mTOR) signaling pathway members were investigated by Western blot and quantitative reverse transcription-polymerase chain reaction, respectively. The relationship between enteric glial cells (EGCs) and autophagy was observed by confocal immunofluorescence microscopy, localization analysis, and electron microscopy.@*RESULTS@#EA treatment shortened the first black stool defecation time, increased the number, weight, and water content of 8-h feces, and improved the intestinal transit rate in FC mice (P<0.01). In terms of a putative autophagy mechanism, EA treatment promoted the expressions of LC3 and Beclin-1 proteins in the colonic tissue of FC mice (P<0.05), with glial fibrillary acidic protein (GFAP) and LC3 significantly colocalized. Furthermore, EA promoted colonic autophagy in FC mice by inhibiting PI3K/AKT/mTOR signaling (P<0.05 or P<0.01). The positive effect of EA on intestinal motility in FC mice was blocked by 3-MA.@*CONCLUSION@#EA treatment can inhibit PI3K/AKT/mTOR signaling in the colonic tissues of FC mice, thereby promoting EGCs autophagy to improve intestinal motility.

This study aimed to analyze the biological foundation and biomarkers of stable coronary heart disease(CHD) with phlegm and blood stasis(PBS) syndrome based on RNA-seq and network pharmacology. Peripheral blood nucleated cells from five CHD patients with PBS syndrome, five CHD patients with non-PBS syndrome, and five healthy adults were collected for RNA-seq. The specific targets of CHD with PBS syndrome were determined by differential gene expression analysis and Venn diagram analysis. The active ingredients of Danlou Tablets were screened out from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the "component-target" prediction was completed through PubChem and SwissTargetPrediction. The "drug-ingredient-target-signaling pathway" network of Danlou Tablets against CHD with PBS syndrome was optimized by Cytoscape software. After the target biomarkers were identified, 90 participants were enrolled for diagnostic tests, and 30 CHD patients with PBS syndrome were included in before-and-after experiment to determine the therapeutic effect of Danlou Tablets on those targets. As revealed by RNA-seq and Venn diagram analysis, 200 specific genes were identified for CHD with PBS syndrome. A total of 1 118 potential therapeutic targets of Danlou Tablets were predicted through network pharmacology. Through integrated analysis of the two gene sets, 13 key targets of Danlou Tablets in the treatment of CHD with PBS syndrome were screened out, including CSF1, AKR1C2, PDGFRB, ARG1, CNR2, ALOX15B, ALDH1A1, CTSL, PLA2G7, LAP3, AKR1C3, IGFBP3, and CA1. They were presumably the biomarkers of CHD with PBS syndrome. The ELISA test further showed that CSF1 was significantly up-regulated in the peripheral blood of CHD patients with PBS syndrome, and was significantly down-regulated after Danlou Tablets intervention. CSF1 may be a biomarker for CHD with PBS syndrome, and it is positively correlated with the severity of the disease. The diagnostic cut-off of CSF1 for CHD with PBS syndrome was 286 pg·mL~(-1).

Tong (dredging) method in traditional Chinese medicine (TCM) emphasizes soothing the stagnated Qi, blood, and body fluid in zang-fu organs, meridians, and collaterals to remove pathogens, reinforce vital Qi, and balance Yin and Yang of the human body. Tong method can be adopted to disperse sweat pore, attack pathogenic Qi, harmonize Yin and Yang, as well as tonify deficiency, and resolve stagnation. It has been proved effective in treating coronary heart disease (CHD), which falls into the category of "chest impediment and heart pain" in TCM, with the key pathogenesis lying in blood vessel obstruction. Therefore, dredging blood vessels is the primary therapeutic principle for CHD. Specifically, there are four aspects. The first is dispersing and dredging the sweat pore of the heart. If the sweat pore is occluded by pathogenic cold, which makes Yang-qi undissipated, Cinnamomi Ramulus, Piperis Longi Fructus, Alpiniae Officinarum Rhizoma, and Asari Radix et Rhizoma can be prescribed for warming and dredging heart Yang. If the Yang-qi of the heart and chest stagnated in the body, which hinders Qi and blood to nourish the myocardium, resulting in chest pain, Poria and Alismatis Rhizoma can be prescribed. For CHD due to atherosclerosis and inflammation, heat-clearing, toxin-removing, and inflammation-resisting Chinese medicinal herbs such as Coptidis Rhizoma and Rhei Radix et Rhizoma are recommended. The second is attacking and dredging the collaterals of the heart. Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Notoginseng Radix et Rhizoma, etc. can be prescribed for blood stasis, Trichosanthis Fructus, Allii Macrostemonis Bulbus, Pinelliae Rhizoma, etc. for phlegm, and Aquilariae Lignum Resinatum, Euodiae Fructus, etc. for pathogenic cold. Since the chronic disease can affect collaterals, Moschus and Santali Albi Lignum can be added to promote blood circulation and remove the obstruction of collaterals of the heart. The third is harmonizing and dredging the mind. Cinnamomi Ramulus, Coptidis Rhizoma, Cinnamomi Cortex, etc. are selected for restoring the coordination between the heart and the kidney. According to the specific syndrome, the methods of nourishing the mind and calming the nerves through tranquilizing the mind, calming down the mind, and inducing resuscitation can be selected using such Chinese medicines as Ziziphi Spinosae Semen, Polygalae Radix, and Draconis Ossa. The fourth is tonifying and dredging the Qi and blood of the heart. The deficiency syndrome of CHD is divided into Qi deficiency and kidney deficiency. Invigorating Qi and strengthening the heart are the first essentials for the treatment of CHD. In Qi invigoration, Qi and blood must be strengthened simultaneously to strengthen the heart and clear the pulse. Hence, Bazhentang modified by Salviae Miltiorrhizae Radix et Rhizoma and Carthami Flos can be chosen. In kidney Qi tonifying, kidney and heart must be strengthened simultaneously, and the methods of tonifying kidney and activating blood can be used. Ginseng Radix et Rhizoma and Astragali Radix are considered as the first choice for tonifying heart Qi, and Epimedii Folium and Morindae Officinalis Radix for tonifying kidney Qi, which are added with Salviae Miltiorrhizae Radix et Rhizoma and Rehmanniae Radix Praeparata to obtain the kidney-tonifying and blood-activating prescription. It is suitable for treating CHD due to kidney deficiency and blood stasis. Simultaneous treatment of heart and kidney is more suitable for middle-aged and elderly patients and chronically ill patients. Tong method can be used in various clinical diseases as well as CHD.
ABSTRACT
BACKGROUND@#Functional constipation (FC) is one of the most prevalent functional gastrointestinal disorders. Dissatisfaction with medications prescribed to treat FC may lead patients to seek alternative treatments. Numerous systematic reviews (SRs) examining the use of acupuncture to treat FC have reported inconsistent results, and the quality of these studies has not been fully evaluated.@*OBJECTIVE@#In this overview, we evaluated and summarized clinical evidence on the effectiveness and safety of acupuncture for treating FC and evaluated the quality and bias of the SRs we reviewed.@*SEARCH STRATEGY@#The search strategy was structured by medical subject headings and search terms such as "acupuncture therapy" and "functional constipation." Electronic searches were conducted in eight databases from their inception to September 2020.@*INCLUSION CRITERIA@#SRs that investigated the effectiveness and safety of acupuncture for managing FC were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted information and appraised the methodology, reporting accuracy, quality of evidence, and risk of bias using the following critical appraisal tools: (1) A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2); (2) Risk of Bias in Systematic Reviews (ROBIS); (3) Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A); and (4) the Grading of Recommendations, Assessment, Development and Evaluations (GRADE). A κ index was used to score the level of agreement between the 2 reviewers.@*RESULTS@#Thirteen SRs that examined the clinical utility of acupuncture for treating FC were identified. Using the AMSTAR 2 tool, we rated 92.3% (12/13) of the SRs as "critically low" confidence and one study as "low" confidence. Using the ROBIS criteria, 38.5% (5/13) of the SRs were considered to have "low risk" of bias. Based on PRISMA-A, 76.9% (10/13) of the SRs had over 70% compliance with reporting standards. The inter-rater agreement was good for AMSTAR 2, ROBIS, and PRISMA-A. Using the GRADE tool, we classified 22.5% (9/40) of the measured outcomes as "moderate" quality, 57.5% (23/40) as "low" quality, and 20.0% (8/40) as "very low" quality. The inter-rater agreement was moderate when using GRADE. Descriptive analyses indicated that acupuncture was more efficacious than sham acupuncture for improving weekly complete spontaneous bowel movements (CSBMs) and for raising the Bristol Stool Form Scale (BSFS) score. Acupuncture appeared to be superior to anti-constipation drugs for improving weekly spontaneous bowel movements, the total effective rate, and the Patient Assessment of Constipation Quality of Life score. Although ten SRs mentioned the occurrence of adverse events, serious adverse events were not associated with acupuncture treatment.@*CONCLUSION@#Acupuncture may be more efficacious than sham acupuncture for improving CSBMs and BSFS scores and may be superior to anti-constipation drugs for improving bowel movement frequency, as well as quality of life. Limitations to current studies and inconsistent evidence suggest a need for more rigorous and methodologically sound SRs to draw definitive conclusions.@*SYSTEMATIC REVIEW REGISTRATION@#PROSPERO CRD42020189173.

BACKGROUND@#Chronic urticaria (CU) is a common skin disease, which has a negative effect on quality of life. Current treatments do not fully control the symptoms of urticaria for many CU patients, thus effective and safe treatments for CU are still needed.@*OBJECTIVE@#This review aims to evaluate the effectiveness and safety of cupping therapy in patients with CU.@*SEARCH STRATEGY@#The search strategy looked for the presence of related keywords, such as "chronic urticaria" and "cupping therapy," in the title and abstract of research articles indexed in major databases. Randomized controlled trials (RCTs) were selected after querying nine electronic databases from their inception to May 2019 with the above search terms.@*INCLUSION CRITERIA@#RCTs were included if they recruited patients with CU who were intervened with dry or wet cupping. Publications could be written in Chinese or English.@*DATA EXTRACTION AND ANALYSIS@#Data were extracted, and the studies were assessed for the quality of their methodological design and risk of bias. Meta-analyses of the RCT data were conducted to assess the total effective rate of the treatment as the primary outcome. Skin disease quality of life index score, recurrence rate, and adverse events were assessed as secondary outcomes. Subgroup analyses were conducted based on different interventions.@*RESULTS@#Thirteen comparisons from 12 RCTs involving 842 participants were included. There were no significant differences between wet cupping and medications in total effective rate (n = 372; risk ratio [RR] = 1.10, 95% confidence interval [CI] 0.97 to 1.25; P = 0.14) or recurrence rate (n = 240; RR = 0.56, 95% CI 0.23 to 1.36; P = 0.20). Cupping therapy, in combination with antihistamine treatment was more efficacious than antihistamines alone, with a greater total effective rate (n = 342; RR = 1.18, 95% CI 1.01 to 1.39; P = 0.03) and lower recurrence rate (n = 342; RR = 0.52, 95% CI 0.32 to 0.84; P = 0.007). Cupping therapy combined with acupuncture was more effective than acupuncture alone (n = 156; RR = 1.25, 95% CI 1.07 to 1.46; P = 0.006). No serious adverse events were reported.@*CONCLUSION@#Wet cupping may be as effective as treatment with antihistamines. When cupping therapy is used as an adjuvant therapy to antihistamines or acupuncture, it may enhance the efficacy. Results drawn from these studies should be interpreted with caution and applied with care to clinical practice, because of the poor quality among the studies that were reviewed.@*SYSTEMATIC REVIEW REGISTRATION@#PROSPERO, CRD42019137451.

The data in literature of acupuncture and moxibustion on treatment of diarrhea from pre-Qin period to Qing dynasty was collected to establish prescription database and characteristics and rules of ancient acupuncture and moxibustion for diarrhea were analyzed with data mining technology. Totally 235 papers were collected and 76 acupoints were involved with 439 times of selection. The number and times of special acupoints were 72.37% (55/76) and 76.99% (338/439), respectively, which was more seen in front-mu acupoint and back-shu acupoint. The acupoints were distributed among 11 meridians. Moxibustion was applied in 53 papers while combination of acupuncture and moxibustion was used in 1 literature. As a result, acupuncture and moxibustion for diarrhea in ancient pay much attention on acupoint in back and abdomen, in which Tianshu (ST 25), Shen-que (CV 8), Guanyuan (CV 4) and Dachangshu (BL 25) were the most frequently used. The compatibility of front-mu acupoint and back-shu acupoint was very common. Selection of special acupoint was dominant. Besides crossing points that has the most intersection of meridian qi in the back and abdomen, acupoints below the elbow and knee joints, such as five-shu points, source point, luo-connecting point, eight confluence point and lower he-sea point were also taken into account. As for compatibility of special acupoints, the supportive degree between back-shu acupoint and confluence points or front-mu acupoint was the highest; the selections of meridians mainly were Bladder Meridian, Conception Vessel and Spleen Meridian; and application of moxibustion was highly valued. In conclusion, it is feasible to apply data mining technology to the clinical literature research of ancient acupuncture and moxibustion, which can provide evidence for summary of the traditional classical theory.

ABSTRACT Clinical application of standards for reporting interventions in clinical trials of acupuncture (STRICTA) is introduced in this article, and improving opinions are proposed as well. STRICTA has already been extensively applied in designation of acupuncture clinical trials, composition of articles and quality assessment of acupuncture literature. According to the present version of STRICTA, it is suggested that items such as "standards and methods on acupoint selection and location", "angle and direction of needle insertion" and "whether the subjects ever have been acupunctured" should be further perfected. Individuated treat protocols which is highlighted on treatment according to differentiation of syndromes according to different opportunities and stages of diseases should be promoted so as to give better expression to the characteristics of Chinese medicine and enhance the clinical value of the relative literature.
