Research on the development methodology for clinical practice guidelines for organic integration of traditional Chinese and Western medicine.

Integrated traditional Chinese medicine (TCM) and Western medicine (WM) is a new medical science grounded in the knowledge bases of both TCM and WM, which then forms a unique modern medical system in China. Integrated TCM and WM has a long history in China, and has made important achievements in the process of clinical diagnosis and treatment. However, the methodological defects in currently published clinical practice guidelines limit its development. The organic integration of TCM and WM is a deeper integration of TCM and WM. To realize the progression of "integration" to "organic integration", a targeted and standardized guideline development methodology is needed. Therefore, the purpose of this study is to establish a standardized development procedure for clinical practice guidelines for the organic integration of TCM and WM to promote the systematic integration of TCM and WM research results into clinical practice guidelines in order to achieve optimal results as the whole is greater than the sum of the parts.

[Medication rules of traditional Chinese medicine compounds for pain].

The present study collected data on traditional Chinese medicine(TCM) compounds effective in relieving pain from the patent database of the State Intellectual Property Office(SIPO), sorted out the TCM compounds against pain in patents, and analyzed the medication rules to provide references for the research and development of new TCM drugs against pain. The data were subjected to frequency statistics, association rules, cluster analysis, and complex network analysis by IBM SPSS Modeler 18.3 and SPSS Statistical 26.0. The results showed that among the 101 oral prescriptions included in the statistics, the top 5 drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma, and among the 49 external prescriptions included in the statistics, the top 5 drugs were Myrrha, Olibanum, Angelicae Dahuricae Radix, Borneolum Syntheticum, and Chuanxiong Rhizoma. Whether oral or external prescriptions, the drugs were mainly warm in nature, and bitter, pungent, and sweet in flavor. According to TCM complex network analysis, the core drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, and Chuanxiong Rhizoma in oral prescriptions, and Olibanum, Myrrha, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Angelicae Sinensis Radix in external prescriptions. Overall, the therapeutic principles of oral prescriptions were mainly replenishing Qi, nourishing blood, and promoting Qi and blood circulation, while those of external prescriptions were activating blood, resolving stasis, promoting Qi flow, and relieving pain on the basis of the oral prescriptions. In the future research and development of TCM compounds against pain, the prescriptions should be modified with mind-tranquilizing and depression-relieving drugs. With the modernization of TCM, the development of new pain-relieving TCM compound patents based on ancient methods and clinical experience adhering to the guidance of TCM treatment based on syndrome differentiation can meet the new demand for pain treatment in the current society and give full play to the advantages of TCM in pain treatment.

[Meta-analysis of effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention].

To systemically evaluate the effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention(PCI). A total of 7 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and Web of Science were searched by computer to collect the randomized controlled trials(RCTs) on Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients with coronary heart disease after PCI with the retrieval time from the database establishment to April 1, 2020. Two researchers independently conducted li-terature screening, data extraction and bias risk assessment. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 31 RCTs were included, involving 3 537 patients. The results of Meta-analysis showed that in terms of major adverse cardiovascular events(MACE) after PCI, the combination of Qishen Yiqi Dripping Pills could significantly reduce the recurrence of angina pectoris, incidence of arrhythmia, heart failure and re-revascularization, and the effect was better than that of Western medicine treatment alone. However, there was no significant difference between the two groups in the improvement of non-fatal myocardial infarction, cardiac death, stent restenosis, stroke and other adverse cardiovascular events. In terms of improving left ventricular ejection fraction(LVEF), 6 min walking test(6 MWT), high-sensitivity C-reactive protein(hs-CRP) and Seattle angina pectoris scale(SAQ), the combination of Qishen Yiqi Dripping Pills and Western medicine treatment had obvious advantages over Western medicine treatment alone in increasing LVEF, 6 MWT and SAQ, and reducing the level of hs-CRP, with statistically significant differences. There were few adverse reactions in both groups, and there was no significant difference between the two groups. The main manifestations were gastrointestinal reactions, rash, gingiva and other small bleeding, and no serious adverse reactions occurred. The above reactions could disappear after drug withdrawal or symptomatic treatment. The application of Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients after PCI could reduce the occurrence of MACE, improve the clinical efficacy, quality of life and prognosis in a safe and reliable manner. However, due to the quantity and quality limitations of included studies, more standardized, rigo-rous and high-quality clinical studies are still needed to further verify the above conclusions.

Kirenol, darutoside and hesperidin contribute to the anti-inflammatory and analgesic activities of Siegesbeckia pubescens makino by inhibiting COX-2 expression and inflammatory cell infiltration.

ETHNOPHARMACOLOGICAL RELEVANCE: The Chinese traditional medicine of Siegesbeckia pubescens Makino (SM), which has the effect of healing rheumatism and promoting joint health, is often used to treat rheumatoid arthritis and ischemic stroke. AIM OF THE STUDY: To clarify the mechanisms underlying the anti-inflammatory and analgesic influence of active components in the ethanol extract of Siegesbeckia pubescens Makino (ESM). MATERIALS AND METHODS: The active ingredients in the ESM were identified practicing high-performance liquid chromatography-diode array detection (HPLC-DAD). Four models including xylene-induced ear oedema, complete Freund's adjuvant (CFA)-induced hind paw oedema, acetic acid-induced pain writhing and lipopolysaccharide (LPS)-induced RAW264.7 cell migration, were used to clarify the anti-inflammatory and analgesic mechanisms of the active ingredients in the ESM. RESULTS: (1) Three active ingredients of kirenol, darutoside and hesperidin were identified in the ESM, with relative proportion of 0.6%, 0.2% and 0.01%, respectively; hesperidin was reported for the first time in the ESM. (2) Both the ESM and its active ingredients could effectively alleviate the degree of swelling of the auricle and toes, increase the threshold of heat pain, decrease the overexpression of inflammatory protein cyclooxygenase-2 (COX-2) in the skin tissue of the tested parts of the toes, and reduce the number of writhes induced by acetic acid in mice. (3) ESM and its active ingredients also dose-dependently inhibited the migration of RAW264.7 cells. CONCLUSIONS: ESM and its active ingredients can effectively attenuate the expression of inflammatory factors induced by chemical inflammation, prevent the infiltration of inflammatory cells, and exert good anti-inflammatory and antinociceptive activities.

Bioactivity-Guided Discovery of Human Carboxylesterase Inhibitors from the Roots of Paeonia lactiflora.

In a continuing search for potential inhibitors against human carboxylesterases 1A1 and 2A1 (hCES1A1 and hCES2A1), an EtOAc extract of the roots of Paeonia lactiflora showed strong hCES inhibition activity. Bioassay-guided fractionation led to the isolation of 26 terpenoids including 12 new ones (1-5, 7-12, and 26). Among these, sesquiterpenoids 1 and 6, monoterpenoids 10, 11, and 13-15, and triterpenoids 18-20, 22, and 24-26 contributed to the hCES2A1 inhibition, in the IC50 range of 1.9-14.5 µM, while the pentacyclic triterpenoids 18-26 were responsible for the potent inhibitory activity against hCES1A1, with IC50 values less than 5.0 µM. The structures of all the compounds were elucidated using MS and 1D and 2D NMR data, and the absolute configurations of the new compounds were resolved via specific rotation, experimental and calculated ECD spectra, and single-crystal X-ray diffraction analysis. The structure-activity relationship analysis highlighted that the free HO-3 group in the pentacyclic triterpenoids is crucial for their potent inhibitory activity against hCES1A1.

[A new lignan glucoside from root of Paeonia lactiflora].

A new lignan glucoside,(+)-fragransin A_2-4-O-ß-D-glucopyranoside(1), has been isolated from the dry root of Paeonia lactiflora by column chromatography on silica gel, Sephadex LH-20, and MCI-gel resin, as well as preparative RP-HPLC. The structure of the new compound was elucidated by spectroscopic data analysis(MS, UV, IR, CD, 1 D and 2 D NMR) and chemical method. Compound 1 showed moderate inhibition against lipopolysaccharide induced nitric oxide production in RAW264.7 macrophages, with an IC_(50) value of 21.3 µmol·L~(-1).

[Effect of Siegesbeckiae Herba in treating chronic pain].

The treatment of pain with complementary and alternative medicine has gradually attracted international attention. Traditional Chinese medicine(TCM) with clear composition and mechanism will become a new starting point for new drug research and development. Siegesbeckiae Herba is a commonly used TCM herb in the treatment of rheumatic arthralgia. With a clear chemical composition, Siegesbeckiae Herba has a long history of clinical application and a certain modern research basis in the treatment of chronic pain. It has good research and development prospects in the treatment of analgesia. Based on the occurrence principle of pain and the known mechanism of action of Siegesbeckiae Herba, we discussed the advance of studies on Siegesbeckiae Herba in three aspects, namely inflammatory pain, neuropathic pain and cancer pain, so as to provide reference for further basic research and development and application of new TCM.

Effect of electroacupuncture on relieving central post-stroke pain by inhibiting autophagy in the hippocampus.

INTRODUCTION: To explore the underlying mechanism of electroacupuncture (EA) treatment on central post-stroke pain (CPSP), and provide basic evidence for the EA treatment on CPSP. METHODS: Firstly, 40 male SD rats were successfully established with a model of CPSP, under the intervention of different EA frequencies (2 Hz and 15 Hz) and fluoxetine (5 ml/kg and 0.4 mg/ml), whose brain tissue was then removed for paraffin-embedded sectioning; secondly, LPS induced the primary brain cells in the hippocampus to cause inflammation model which were added NS398 (inhibitor of COX-2) and DKK-1 (inhibitor of ß-catenin) later. The lesion sites of brain tissue were observed by Nissl staining and Transmission Electron Microscope (TEM) and autophagy-related proteins (LC3B, p62, LAMP-1), COX-2 and ß-catenin were detected by Western Blot and immunohistochemical staining. Finally, the correlation between LC3B, COX-2, and ß-catenin was calculated by multispectral quantification. RESULTS: (1) In the EA group (15 Hz), the number of Nissl bodies increased, autophagy-related protein LC3B-Ⅱ/Ⅰ, LAMP-1, COX-2, and ß-catenin was lowly expressed, p62 was highly expressed; (2) COX-2, ß-catenin and LC3B are positively correlated with each other (COX-2 & ß-catenin: r = 0.923; COX-2 & LC3B: r = 0.818; ß-catenin & LC3B: r = 0.801); (3) Nissl bodies of primary brain cells of the hippocampus under LPS were like animal experiments; after addition of DKK-1, high expression of ß-catenin and COX-2 induced by LPS was significantly down-regulated, and LC3B-II/I was significantly down-regulated, and p62 protein only had up-regulation trend; after addition of NS398, COX-2 and LC3B-II/I was significantly down-regulated. CONCLUSION: EA may inhibit autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression and effectively alleviating CPSP. SIGNIFICANCE STATEMENT: Previous studies have found that EA can reduce the expression of NK-1R in damaged rats by inhibition of COX-2 and ß-catenin loops, which controls the activation of glial cells in the damaged area and the apoptosis of neuronal cells, and alleviated pain. In the male SD rat model, we evaluated this effect that EA inhibits autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression in the brain tissue. In addition, we assessed expression levels of autophagy-related proteins and genes on the inflammatory primary brain cells model. From the experiment, we found EA may inhibit autophagy in the hippocampus by reducing ß-catenin/COX-2 protein expression. These findings provide a foundation for the interpretation of the mechanism of EA on relieving CPSP in clinical practice.

[Research progress of natural alkaloids with analgesic activity].

Pain is a protective defense response of the body to harmful stimuli. Long-term pain not only seriously affects the body of the patient and brings great pain to the patient, but also brings huge economic burden to the patient's family and society. It has become one of the most serious problems affecting human health. At present, opioids and non-steroidal anti-inflammatory drugs(NSAIDs) are commonly used as painkillers, but they tend to cause a variety of adverse reactions or risk of addiction. To find and develop new analgesic drugs, which are safer and more effective, has become the hot spot and difficulty in medical research. A variety of alkaloids derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical analgesic medicines. Various alkaloids have been proved to have good analgesic effects, such as morphine and the related to opioids, the main analgesic active components from Corydalis Rhizoma and Aconiti Lateralis Radix Praeparata. Here we summarized the research progress of natural alkaloids with analgesic activity, in order to provide reference for the research and development of analgesic drugs based on natural products.

[Research progress of natural non-alkaloids with analgesic activity].

Pain is a complex, unpleasant feeling and emotional experience associated with actual or potential tissue damage, and manifests itself in certain autonomous psychological and behavioral responses. The commonly used opioid and non-steroidal anti-inflammatory analgesics(NSAIDs) may cause adverse reactions to the kidney, liver, cardiovascular or gastrointestinal system and cause problems of drug abuse. Therefore, it is necessary to study new analgesic drugs with less side effects and significant analgesic effects. A variety of natural products derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical medicines and provide an inexhaustible resource for the development and innovation of modern medicines. Therefore, this paper mainly reviews the natural non-alkaloids with analgesic activity in order to provide reference for the research and development of analgesic drugs derived from natural products.

[Research progress on animal models of chronic pain and its application in traditional Chinese medicine research].

The classification of chronic pain is complex and its pathogenesis is not clear, which led to the limited progress of treatment measures.Traditional Chinese medicine(TCM) has certain advantages in the treatment of chronic pain, and its mechanism needs further exploration. The ideal animal model is helpful to elucidate the key mechanism of the occurrence and development of chronic pain and play an important role in the discovery of new drug targets, the development of new therapies and the research on the analgesic mechanism of TCM.In recent years, many scholars at home and abroad have done a lot of research to explore the pathogenesis of chronic pain and the mechanism of TCM, which have achieved some results. On this basis, this study summarizes the selection of experimental animals for chronic pain and the commonly evaluation methods of animal models. According to the latest international classification of diseases, this review organizes the induced methods, evaluation indicators, advantages and disadvantages of seven kinds of chronic pain animal models, such as chronic primary pain, chronic cancer-related pain and so on. Next, this review introduces the chronic pain animal models commonly used in TCM research, in order to provide guidance for the targeted selection of animal models when carrying out relevant experiments in the future.

An Overview of Systematic Reviews of Randomized Controlled Trials on Acupuncture Treating Migraine.

Objectives: To review the evidence of acupuncture for acute and preventive treatment of migraine for further awareness of the effect of acupuncture for migraine. Design: An overview of systematic reviews and meta-analyses (SR/MAs) for randomized controlled trials. Material and Methods: We searched PubMed, Embase, the Cochrane Library, China Knowledge Resource Integrated Database, VIP Chinese Journal Full Text Database, WANFANG Data, and China Biology Medicine disc from their establishment to May 27, 2018. SR/MAs of randomized controlled trials comparing the effect of the acupuncture intervention with another treatment control in migraine patients were included. Results: 428 SRs were identified, and 15 of them were included. Only 4 SR/MAs were assessed by GRADE, which showed certainty of most evidence being low or very low. Assessed by AMSTAR-2, fourteen was critically low rating overall confidence in the results, and 1 was low rating overall confidence in the results. Evidence suggested that acupuncture has a significant advantage of pain improvement, efficacy, and safety relative to blank control, sham acupuncture, or drug treatment, but some of these results are contradictory. Conclusions: We found that acupuncture on treating migraine has the advantage for pain improvement and safety, but the quality of SR/MAs of acupuncture for migraine remains to be improved.

CONSORT extension for reporting N-of-1 trials for traditional Chinese medicine (CENT for TCM) : Recommendations, explanation and elaboration.

BACKGROUND: N-of-1 trial is a desired and appropriate approach to assessing the efficacy and safety of traditional Chinese medicine (TCM) interventions. There have been an increasing number of N-of-1 trials for TCM published. However, a lack of preferred reporting guidance led in the general poor reporting quality of these trials. Due to the unique characteristics of TCM, the working group developed this CONSORT Extension for reporting N-of-1 Trials for Traditional Chinese Medicine (CENT for TCM) to assist TCM researchers in reporting N-of-1 trials for TCM. METHODS: We registered CENT for TCM at the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network (available at equator-network.org). The development was a comprehensive process through collection of the initial reporting items, two-round scientific Delphi consensus survey with 17 panelists, revision and formation of the final reporting checklist. RESULTS: The checklist includes 25 items within six domains, eight items in which were extended and elaborated on the items of the CENT 2015 checklist. Explanation of the items were listed adequately considering the nature of TCM, introducing the concept of TCM syndrome differentiation and TCM interventions. CONCLUSIONS: CENT for TCM can be used to assess the completeness of the reporting of N-of-1 trials for TCM. The working group expect that CENT for TCM could be a practical tool to enhance the comprehensiveness and transparency of the design, implementation and reporting of N-of-1 trials for TCM.

Adverse drug reactions of Yunnan Baiyao capsule: a multi-center intensive monitoring study in China.

BACKGROUND: Yunnan Baiyao capsule (YBC), a marketed herbal medicine in mainland China, is widely used to control bleeding. This study's aim was to determine the occurrence of YBC-related adverse drug reactions (ADRs) among users of the medicine. METHODS: This hospital-intensive monitoring study was conducted in 163 hospitals across China. Consumers who used YBC (Z53020799) between June 2015 and December 2016 were included. By face-to-face interview or telephone, the circumstances and experiences of their adverse events (AEs), during drug taking and 14 days after drug withdrawal, were recorded at follow-up and later encoded by International Conference on Harmonisation (ICH) 1997. The Naranjo Adverse Reaction Probability Scale (APS) was used to determine the likelihood of ADRs. RESULTS: A total of 31,556 participants were included (follow-up rate 99.40%). AEs occurred in 742 participants, of which 561 were reported as "not related with drug use" by their physician-in-charge. Based on the remaining 181 cases, the overall ADR incidence was 1.17% (intention to treat) and 0.58% (per protocol), with abnormal findings mainly concentrated in the digestive system, skin and respiratory system. The top 5 frequently reported reactions were nausea and vomiting (0.1785%, 56 cases of 31,367 participants), functional diarrhea (0.1180%, 37 of 31,367 participants), stomach discomfort (0.0893%, 28 of 31,367 participants), rash (0.0574%, 18 of 31,367 participants) and gastro-esophageal reflux (0.0383%, 12 of 31,367 participants). Among them, functional diarrhea and stomach discomfort were judged as definite ADRs of YBC. CONCLUSIONS: In this large study, treatment of YBC was found to be associated with ADRs with an incidence of 1.17%, although most were relatively mild and not considered to be life-threatening.

The Effect of Acupuncture on the Quality of Life in Patients With Migraine: A Systematic Review and Meta-Analysis.

Background: Acupuncture is frequently used as an efficient method to prevent and treat migraines. However, its effect on the quality of life remains controversial. Methods: Seven databases, such as PubMed and Cochrane Library were searched to retrieve reference lists of eligible trials and related reviews. Randomized controlled trials that were published in Chinese and English were included. Results: Acupuncture resulted in lower Visual Analog Scale scores than the medication group at 1 month after treatment (MD -1.22, 95%CI -1.57 to -0.87; low quality) and 1-3 months after treatment (MD -1.81, 95%CI -3.42 to -0.20; low quality). Compared with sham acupuncture, acupuncture resulted in lower Visual Analog Scale scores at 1 month after treatment (MD -1.56, 95%CI -2.21 to -0.92; low quality). Conclusion: Acupuncture exhibits certain efficacy both in the treatment and prevention of migraines, which is superior to no treatment, sham acupuncture and medication. Further, acupuncture enhanced the quality of life more than did medication.

The Ethanol Supernatant Extracts of Liushenwan Could Alleviate Nanodiethylnitrosamine-Induced Liver Cancer in Mice.

Liver cancer is one of the leading causes of cancerous deaths worldwide. At present, the treatment of hepatocellular carcinoma (HCC) remains to be a problem globally. Liushenwan (LSW), an ancient Chinese medicine previously used to treat localized infections, was recently reported to possess anticancer activity. Here in this study, we aim to examine the effect of LSW-ET (LSW-ET is the supernatant fraction of LSW from ultrasound assisted ethanol extraction) in prevention and treatment on nanodiethylnitrosamine- (nanoDEN-) induced HCC in mice. In nanoDEN-induced HCC mice treated with LSW-ET by oral (po) or intragastric gavage (ig), we observed an alleviation of serum ALT and AST levels, amelioration in histopathological stainings, and an inhibition in liver tumor growth. In addition, compared with the nanoDEN group, downregulation of multiple pivotal factors (COX-2, ß-catenin, PCNA, and HMGB-1) was observed in LSW-ET-po and LSW-ET-ig groups. Taken together, the delivery of LSW-ET by oral could be a potential prevention and treatment of liver cancer.

Extract of the Blood Circulation-Promoting Recipe-84 Can Protect Rat Retinas by Inhibiting the ß-Catenin Signaling Pathway.

Extract of the Blood Circulation-Promoting Recipe (EBR-84) from the Chinese Herbal medicine "Blood Circulation Promoting Recipe" could retard retinopathy development. This study investigated whether EBR-84 protects retinas by inhibiting the ß-catenin pathway using a rat model of retinopathy and a retinal ganglion cell 5 (RGC-5) cell death model. RGC death was induced by either N-methyl-d-aspartic acid (NMDA) or TWS119 (an activator of the ß-catenin pathway). After the corresponding treatment with EBR-84, RGC death and the protein expression levels of ß-catenin, cyclooxygenase-2 (COX-2), and vascular endothelial growth factor (VEGF) in rat retinas were examined. ß-Catenin accumulated in the retinal ganglion cell layer (GCL) of NMDA-treated rats. EBR-84 (3.9, 7.8, and 15.6 g/kg) significantly attenuated the NMDA-induced RGC loss accompanying the reduction of ß-catenin expression. Moreover, the expression levels of COX-2 and VEGF were decreased by EBR-84 in a dose-dependent manner. For the TWS119-treated rats, EBR-84 also ameliorated RGC loss and lowered the expression levels of ß-catenin, COX-2, and VEGF. In vitro, EBR-84 increased the viability of NMDA-treated RGC-5 while decreased ß-catenin expression. In conclusion, EBR-84 retarded ratretinopathy, and the ß-catenin signaling pathway played an important role during this protective process.

Systematic Reviews/Meta-Analyses of Integrative Medicine in Chinese Need Regulation and Monitoring Urgently and Some Suggestions for Its Solutions.

With the introduction and development of evidence-based medicine in China, it has been spread rapidly in the area of integrative medicine (IM) and has become a new unique discipline. During almost 20 years, as one of the most important parts of evidence-based IM, systematic review (SR)/meta-analysis (MA) of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, forming qualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process.

Shengfu Oil Enhances the Healing of Full-Thickness Scalded Skin Accompanying the Differential Regulation of ß-Catenin, Dlk1, and COX-2.

Shengfu oil is a traditional Chinese medicine formula containing 16 ingredients, including Scutellariae radix, Olibanum, and Rehmanniae radix. In this study, we aimed to enhance the wound healing of rabbit full-thickness scalded skin by Shengfu oil and to elucidate its regulatory effects on ß-catenin, Dlk1, and COX-2. We found that Shengfu oil exhibited significant anti-inflammatory, analgesic, and antimicrobial activities. The structure of wound tissues in Shengfu oil group was intact, including regenerated cutaneous appendages, indicating better healing capability of Shengfu oil compared to the controls. The protein expression of ß-catenin, Dlk1, and COX-2 in wound tissues were investigated by immunohistochemistry staining and were further quantitated with the use of multispectral imaging analysis. The protein expression of ß-catenin and Dlk1 in the Shengfu oil group was higher than that in the sesame oil group in early wound repair, accompanied by the lower expression of COX-2; the protein expression of ß-catenin decreased in the middle of wound healing; the protein expression of ß-catenin and Dlk1 increased at the end of wound healing. These results strongly suggest that Shengfu oil can enhance wound healing by regulating the expression of ß-catenin, Dlk1, and COX-2 due to its excellent anti-inflammatory, analgesic, and antimicrobial activities.

A summary and evaluation of current evidence for myocardial infarction with Chinese medicine.

OBJECTIVE: To provide evidence-based recommendations for clinical application and provoke thoughts for future researchers by conducting a comprehensive summary and evaluation of the current evidence profile for the role of Chinese medicine (CM) in treating myocardial infarction (MI). METHODS: Online databases including PubMed, EMBase, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Medicine (CBM), VIP Journal Integration Platform, and Wanfang database were systematically searched for literatures on CM in treating MI. After screening, studies were categorized into 5 types, i.e. systematic review (SR), randomized controlled trial (RCT), observational study, case report and basic research. General information was abstracted, and the quality levels of these studies and their conclusions were summarized and assessed. RESULTS: A total of 452 studies including 10 SRs, 123 RCTs, 47 observational studies, 28 case reports, and 244 basic researches were selected. Clinical studies centered primarily on herbal decoction and mostly were not rigorously performed. High-quality studies were predominantly on Chinese patent medicines (CPMs) such as Danshen Injection (), Shenmai Injection (), Shengmai Injection () and Qishen Yiqi Dripping Pills (). The most frequently observed pattern of drug combination was decoction plus injection. Results of SRs and clinical studies showed that CM may reduce mortality, decrease risk of complication, reduce myocardial injury, improve cardiac function and inhibit ventricular remodeling. Findings from basic researches also supported the positive role of CM in reducing infarct size and myocardial injury, promoting angiogenesis, preventing ventricular remodeling and improving cardiac function. According to the current evidence body, CM has proven effects in the prevention and treatment of MI. It is also found that the effects of CPMs vary with indications. For instance, Shenmai Injection has been found to be especially effective for reducing the incidence of acute clinical events, while CPMs with qi-nourishing and bloodcirculating properties have been proven to be effective in inhibiting ventricular remodeling. High quality evidence supports the use of CM injection for acute MI and CPM for secondary prevention. Reports on adverse events and other safety outcomes associated with CM for MI are scarce. CONCLUSIONS: Sufficient evidence supported the use of CM as an adjuvant to Western medicine for preventing and treating MI. The choice of drug use varies with disease stage and treatment objective. However, the quality of the evidence body remains to be enhanced.
