RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Ferulic acid (FA) has shown potential therapeutic applications in treating lung diseases. However, the underlying mechanisms by which FA ameliorates acute lung injury (ALI) have not been distinctly elucidated. AIM OF THE STUDY: The project aims to observe the therapeutic effects of FA on lipopolysaccharide-induced ALI and to elucidate its specific mechanisms in regulating epithelial sodium channel (ENaC), which majors in alveolar fluid clearance during ALI. MATERIALS AND METHODS: In this study, the possible pathways of FA were determined through network pharmacology analyses. The mechanisms of FA in ALI were verified by in vivo mouse model and in vitro studies, including primary alveolar epithelial type 2 cells and three-dimensional alveolar organoid models. RESULTS: FA ameliorated ALI by improving lung pathological changes, reducing pulmonary edema, and upregulating the α/γ-ENaC expression in C57BL/J male mice. Simultaneously, FA was observed to augment ENaC levels in both three-dimensional alveolar organoid and alveolar epithelial type 2 cells models. Network pharmacology techniques and experimental data from inhibition or knockdown of IkappaB kinase ß (IKKß) proved that FA reduced the phosphorylation of IKKß/nuclear factor-kappaB (NF-κB) and eliminated the lipopolysaccharide-inhibited expression of ENaC, which could be regulated by nuclear protein NF-κB p65 directly. CONCLUSIONS: FA could enhance the expression of ENaC at least in part by inhibiting the IKKß/NF-κB signaling pathway, which may potentially pave the way for promising treatment of ALI.

Objective: Acupuncture, acknowledged as a potent non-pharmacological therapy, is frequently employed to alleviate pain. Despite its widespread use, there has been a lack of overarching bibliometric analysis of clinical research on acupuncture analgesia. We aimed to summarize current patterns, hotspots, and development trends in this field through bibliometric analysis. Methods: This study evaluates academic publications retrieved from the Web of Science database (2010.01-2023.09) concerning acupuncture analgesia in clinical settings. All primary and secondary studies on humans were included. To track global developmental trends, we employed several software for analyzing annual publication volumes, countries/regions, institutions, authors, cited authors, journals, cited journals, references, and keywords and to draw collaborative networks and reference co-citation network maps. Results: The final search encompassed 7,190 relevant studies, including 1,263 randomized controlled trials (RCTs) and 1,293 systematic reviews and meta-analyses. The results indicated a gradual increase in the number of annual publications on acupuncture analgesia in clinical practice. Among countries and institutions, China (2,139) and Chengdu University of Traditional Chinese Medicine (258) ranked first. Liang FR (89 articles) was the most prolific author, while MacPherson H (604) was the most cited author. MEDICINE (455) was the most productive journal, and Pain (2,473/0.20) ranked first in both the frequency and centrality of cited journals. Notably, the most frequently cited reference was a systematic review of individual patient data on acupuncture carried out for chronic pain that was published by Vickers Andrew J in 2012 (156). Burst analysis identified frontier research areas for 2010-2020, encompassing network meta-analysis, case reports, dry needling, lumbar disc herniation, cancer, post-herpetic neuralgia, insomnia, and bibliometric analysis. Conclusion: This study outlines current trends and potential future research hotspots in clinical acupuncture analgesia over the past decade. Findings emphasize the necessity for enhanced international collaboration to improve research output and translation.
RESUMEN
Multiple myeloma (MM) significantly increases the risk of venous thromboembolism (VTE) within 6 months of treatment initiation. The IMPEDE VTE score is a VTE risk prediction model which is recently incorporated into the National Comprehensive Cancer Network (NCCN) guidelines, but it lacks validation among Asians, including Chinese MM patients. We performed a retrospective chart review of 405 Chinese with newly diagnosed MM who started therapy at Beijing Jishuitan Hospital between April 2013 to October 2022. The 6-month cumulative incidence of VTE was 3.8 % (95 % CI:1.6-7.6), 8.6 % (95 % CI: 5.3-21.9) and 40.5 % (95 % CI: 24.9-55.7) in the low-, intermediate- and high-risk groups (P < 0.001), respectively. The C-statistic of the IMPEDE VTE scores for predicting VTE within 6 months of treatment initiation was 0.74 (95 % CI: 0.65-0.83). Of note, in this single-center cohort study, we propose that the anticoagulant LMWH may be more effective than the antiplatelet aspirin in potentially preventing VTE in newly diagnosed MM patients. Our findings suggest that the IMPEDE VTE score is a valid evidence-based risk stratification tool in Chinese patients with newly diagnosed MM.

Artemisia argyi H.Lév. & Vaniot essential oil (AAEO) has shown pharmacological effects such as anti-inflammation, antioxidant, and anti-tumor properties. However, the protective effect of AAEO on lipopolysaccharide (LPS)-induced liver injury and its potential protective mechanism are still unclear. In this study, we used ultra-performance liquid chromatography tandem mass spectrometry metabolomics techniques to investigate the changes in liver tissue metabolites in mice exposed to LPS with or without AAEO treatment for 14 days. The biochemical results showed that compared with the control group, AAEO significantly reduced the levels of liver functional enzymes, suggesting a significant improvement in liver injury. In addition, the 18 differential metabolites identified by metabolomics were mainly involved in the reprogramming of arachidonic acid metabolism, tryptophan metabolism, and purine metabolism. AAEO could significantly inhibit the expression of COX-2, IDO1, and NF-κB; enhance the body's anti-inflammatory ability; and alleviate liver injury. In summary, our study identified the protective mechanism of AAEO on LPS-induced liver injury at the level of small molecular metabolites, providing a potential liver protective agent for the treatment of LPS-induced liver injury.

BACKGROUND: The overall comprehensive consideration of the factors influencing the recommendations in the traditional Chinese medicine (TCM) guidelines remains poorly studied. This study systematically evaluate the factors influencing recommendations formation in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) clinical practice guidelines (CPGs) and TCM CPGs. METHODS: This was a methodological review in which we searched six databases and multiple related websites. The GRADE CPGs were identified as the guidelines developed by the GRADE Working Group or the two Co-Chairs. For the TCM CPGs, we randomly selected guidelines that were published by the TCM or integrative medicine academic societies from China mainland (published by the TCM or integrative medicine academic societies of China mainland). Two reviewers independently screened and extracted data. We included CPGs published in 2018-2022. We extracted information on the influencing factors of evidence to recommendation and conducted the analyses using descriptive statistics and calculated the proportion of relevant items by IBM SPSS Statistics and Microsoft Excel to compare the differences between the GRADE CPGs and the TCM CPGs. RESULTS: Forty-five GRADE CPGs (including 912 recommendations) and 88 TCM CPGs (including 2452 recommendations) were included. TCM recommendations mainly considered the four key determinants of desirable anticipated effects, undesirable anticipated effects, balance between desirable and undesirable effects, certainty of evidence, with less than 20% of other dimensions. And TCM CPGs presented more strong recommendations (for or against) and inappropriate discordant recommendations than GRADE CPGs. GRADE CPGs were more comprehensive considered about the factors affecting the recommendations, and considered more than 70% of all factors in the evidence to recommendation. CONCLUSIONS: The TCM CPGs lack a comprehensive consideration of multiple influencing determinants from evidence to recommendations. In the future, the correct application of the GRADE approaches should be emphasized.

BACKGROUND: Major depressive disorder (MDD) with a history of childhood maltreatment represents a highly prevalent clinical phenotype. Previous studies have demonstrated functional alterations of the thalamus among MDD. However, no study has investigated the static and dynamic changes in functional connectivity (FC) within thalamic subregions among MDD with childhood maltreatment. METHODS: This study included four groups: MDD with childhood maltreatment (n = 48), MDD without childhood maltreatment (n = 30), healthy controls with childhood maltreatment (n = 57), and healthy controls without childhood maltreatment (n = 46). Sixteen thalamic subregions were selected as seed to investigate group-differences in dynamic FC (dFC) and static FC (sFC). Correlation analyses were performed to assess the associations between abnormal FC and maltreatment severity. Eventually, moderation analyses were employed to explore the moderating role of abnormal FC in the relationship between maltreatment and depressive severity. RESULTS: MDD with childhood maltreatment exhibit abnormal thalamic subregions FC compared to MDD without childhood maltreatment, characterized by abnormalities with the sFC of the rostral anterior cingulate cortex, with the dFC of the calcarine, middle cingulate cortex, precuneus cortex and superior temporal gyrus. Furthermore, sFC with the rostral anterior cingulate cortex and dFC with the middle cingulate cortex were correlated with the severity of maltreatment. Additionally, dFC with the superior temporal gyrus moderates the relationship between maltreatment and depression severity. LIMITATIONS: The cross-sectional designs fail to infer causality. CONCLUSIONS: Our findings support thalamic dysfunction as neurobiological features of childhood maltreatment as well as vulnerability to MDD.

Due to various constraints, such as clinical implementation conditions and unique characteristics of acupuncture-moxibustion, some randomized controlled trials (RCTs) of acupuncture-moxibustion still suffer from relatively low quality and limited applicability. The single-arm objective performance criteria/performance goal can be considered as an ideal supplementary and alternative research approach to RCTs. In this paper, the feasibility of applying the single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical research is explored from the limitations of conducting acupuncture-moxibustion RCTs, the principles, the essential design considerations and key statistical steps. In addition, illustrative examples are provided. The objective is to offer insights into resolving practical difficulties in acupuncture-moxibustion clinical research.

OBJECTIVE: To explore the protective effect of Huoxin Pill (HXP) on acute myocardial ischemia-reperfusion (MIRI) injury in rats. METHODS: Seventy-five adult SD rats were divided into the sham-operated group, model group, positive drug group (diltiazem hydrochloride, DH), high dose group (24 mg/kg, HXP-H) and low dose group (12 mg/kg, HXP-L) of Huoxin Pill (n=15 for every group) according to the complete randomization method. After 1 week of intragastric administration, the left anterior descending coronary artery of the rat's heart was ligated for 45 min and reperfused for 3 h. Serum was separated and the levels of creatine kinase (CK), creatine kinase isoenzyme (CK-MB) and lactate dehydrogenase (LDH), superoxide dismutase (SOD), and malondialdehyde (MDA), hypersensitive C-reactive protein (hs-CRP) and interleukin-1ß (IL-1ß) were measured. Myocardial ischemia rate, myocardial infarction rate and myocardial no-reflow rate were determined by staining with Evans blue and 2,3,5-triphenyltetrazolium chloride (TTC). Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine (BATMAN) databases were used to screen for possible active compounds of HXP and their potential therapeutic targets; the results of anti-inflammatory genes associated with MIRI were obtained from GeneCards, Drugbank, Online Mendelian Inheritance in Man (OMIM), and Therapeutic Target Datebase (TTD) databases was performed; Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment were used to analyze the intersected targets; molecular docking was performed using AutoDock Tools. Western blot was used to detect the protein expression of Toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NFκB)/NOD-like receptor protein 3 (NLRP3). RESULTS: Compared with the model group, all doses of HXP significantly reduced the levels of LDH, CK and CK-MB (P<0.05, P<0.01); HXP significantly increased serum activity of SOD (P<0.05, P<0.01); all doses of HXP significantly reduced the levels of hs-CRP and IL-1ß (P<0.05, P<0.01) and the myocardial infarction rate and myocardial no-reflow rate (P<0.01). GO enrichment analysis mainly involved positive regulation of gene expression, extracellular space and identical protein binding, KEGG pathway enrichment mainly involved PI3K-Akt signaling pathway and lipid and atherosclerosis. Molecular docking results showed that kaempferol and luteolin had a better affinity with TLR4, NFκB and NLRP3 molecules. The protein expressions of TLR4, NFκB and NLRP3 were reduced in the HXP group (P<0.01). CONCLUSIONS: HXP has a significant protective effect on myocardial ischemia-reperfusion injury in rats, and its effect may be related to the inhibition of redox response and reduction of the inflammatory response by inhibiting the TLR4NFκB/NLRP3 signaling pathway.

Allergic rhinitis (AR) is a common allergic disease characterized by nasal congestion, rhinorrhoea, and sneezing. Cineole, a monoterpenoid compound widely present in various volatile oils, has a wide range of pharmacological activities and is of interest in allergic airway diseases for its anti-inflammatory and anti-mucus production abilities. However, the protective effects of cineole in mice with allergic rhinitis and its mechanisms have not been well investigated. In this study, the protective effect of cineole against ovalbumin-induced (OVA-induced) allergic rhinitis and its molecular mechanism is investigated by metabolomic analysis based on ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). OVA combined with aluminum hydroxide adjuvant is used to sensitize and establish the allergic rhinitis (AR) mouse model. The mice are randomly divided into groups of control, AR, cineole (30 mg/kg), and budesonide (38.83 µg/kg). The pharmacodynamic results show that cineole significantly reduces the levels of Th2-type cytokines and OVA-specific IgE (OVA-sIgE) in AR mice, improves nasal mucosal tissue damage and alleviates nasal symptoms compared to the untreated AR group. Metabolomic results show that arachidonic acid (AA) metabolism and tryptophan (Trp) metabolism are reprogrammed on the basis of 27 significantly altered metabolites. Further studies show that cineole inhibits the biosynthesis of pro-inflammatory lipid mediators leukotrienes (LTs) and prostaglandins (PGs) in mice by inhibiting the activity of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) in the arachidonic acid metabolic (AA metabolic) pathway. It also inhibits the production of Th2 cytokines and inflammatory cell infiltration, thereby alleviating symptoms such as nasal congestion and nasal leakage. These results reveal the action and molecular mechanism of cineole in alleviating AR and provide a theoretical basis for the clinical application of cineole in treating AR.

Objective: This study aimed to assess the fairness of medical resource allocation in the Yangtze River Economic Belt, based on the Healthy China strategy. It aimed to identify the issues with resource allocation fairness and provide optimization suggestions. Methods: To assess the allocation fairness from a geographical population perspective, the study used the Health Resource Concentration and Entropy Weight TOPSIS methods. Additionally, the study analyzed the allocation fairness from an economic level angle, using the Concentration Curve and Concentration Index. Results: The study found that the downstream area had higher resource allocation fairness than the midstream and upstream areas. The middle reaches had more resources than the upper and lower reaches, based on population concentration. The Entropy Weight TOPSIS method found that Shanghai, Zhejiang, Chongqing, and Jiangsu had the highest comprehensive score index of agglomeration. Furthermore, from 2013 to 2019, the fairness of medical resource distribution gradually improved for different economic levels. Government health expenditure and medical beds were distributed more equitably, while general practitioners had the highest level of unfairness. However, except for medical and health institutions, traditional Chinese medicine institutions, and primary health institutions, other medical resources were mostly distributed to areas with better economic conditions. Conclusion: The study found that the fairness of medical resource allocation in the Yangtze River Economic Belt varied greatly based on geographical population distribution, with inadequate spatial accessibility and service accessibility. Although the fairness of distribution based on economic levels improved over time, medical resources were still concentrated in better economic areas. The study recommends improving regional coordinated development to enhance the fairness of medical resource allocation in the Yangtze River Economic Belt.

The prevalence of hyperlipidemia has increased significantly due to genetic, dietary, nutritional and pharmacological factors, and has become one of the most common pathological conditions in humans. Hyperlipidemia can lead to a range of diseases such as atherosclerosis, stroke, coronary heart disease, myocardial infarction, diabetes, and kidney failure, etc. High circulating low-density lipoprotein cholesterol (LDL-C) is one of the causes of hyperlipidemia. LDL-C in the blood binds to LDL receptor (LDLR) and regulates cholesterol homeostasis through endocytosis. In contrast, proprotein convertase subtilisin/kexin type 9 (PCSK9) mediates LDLR degradation via the intracellular and extracellular pathways, leading to hyperlipidemia. Targeting PCSK9-synthesizing transcription factors and downstream molecules are important for development of new lipid-lowering drugs. Clinical trials regarding PCSK9 inhibitors have demonstrated a reduction in atherosclerotic cardiovascular disease events. The purpose of this review was to explore the target and mechanism of intracellular and extracellular pathways in degradation of LDLR and related drugs by PCSK9 in order to open up a new pathway for the development of new lipid-lowering drugs.
RESUMEN
Giant condylomata acuminata (a sexually transmitted disease caused by HPV infection) currently is treated in many methods. Surgery, the mainstay treatment of giant condylomata acuminata, may cause a high cost or scar formation. It is important to explore effective and safe treatment options. Although the external treatment of traditional Chinese medicine treatment of condyloma acuminatum has not been widely used, in our case, the use of traditional Chinese medicine successfully treated a perianal giant condyloma acuminatum patient who also suffered from mixed hemorrhoid and IgA nephropathy meanwhile. The treatment process was simple and the effect obvious. There was no recurrence more than 10 months after treatment finished, and the patients felt safe, comfortable and highly coordinated. The outcome of this case suggests that the traditional Chinese medicine might be considered as a mild and effective option for the treatment of giant condyloma acuminatum.
RESUMEN
Background: Monkeypox, a zoonotic disease caused by an Orthopoxvirus, presents an etiology similar to smallpox in humans. Currently, there are no licensed treatments for human monkeypox, so clear and urgent research on its prophylaxis and treatment is needed. Objective: The purpose of this study was to explore the evidence of Chinese medicine for contagious pox-like viral diseases and provide suggestions for the multi-country outbreak management of monkeypox. Methods: The review was registered on INPLASY (INPLASY202270013). Ancient classics in China and clinical trials involving randomized controlled trials , non-RCTs, and comparative observational studies of CM on the prevention and treatment of monkeypox, smallpox, measles, varicella, and rubella were retrieved from the Chinese Medical Code (fifth edition), Database of China Ancient Medicine, PubMed, the Cochrane Library, China National Knowledge Infrastructure, Chongqing VIP, Wanfang, Google Scholar, International Clinical Trial Registry Platform, and Chinese Clinical Trial Registry until 6 July 2022. Both quantitative and qualitative methods were applied to present the data collected. Results: The use of CM to control contagious pox-like viral diseases was traced back to ancient Chinese practice cited in Huangdi's Internal Classic, where the pathogen was recorded nearly two thousand years back. There were 85 articles (36 RCTs, eight non-RCTs, one cohort study, and 40 case series) that met the inclusion criteria, of which 39 studies were for measles, 38 for varicella, and eight for rubella. Compared with Western medicine for contagious pox-like viral diseases, CM combined with Western medicine showed significant improvements in fever clearance time (mean difference, -1.42 days; 95% CI, -1.89 to -0.95; 10 RCTs), rash/pox extinction time (MD, -1.71 days; 95% CI, -2.65 to -0.76; six RCTs), and rash/pox scab time (MD, -1.57 days; 95% CI, -1.94 to -1.19; five RCTs). When compared with Western medicine, CM alone could reduce the time of rash/pox extinction and fever clearance. Chinese herbal formulas, including modified Yinqiao powder, modified Xijiao Dihaung decoction, modified Qingjie Toubiao decoction, and modified Shengma Gegen decoction, were frequently applied to treat pox-like viral diseases and also showed significant effects in shortening the time of fever clearance, rash/pox extinction, and rash/pox scabs. Compared with Western medicine (placental globulin) or no intervention, eight non-randomized trials and observational studies on the prevention of contagious pox-like viral diseases showed a significant preventive effect of Leiji powder among high-risk populations. Conclusion: Based on historical records and clinical studies of CM in managing contagious pox-like viral diseases, some botanical drugs could be an alternative approach for treating and preventing human monkeypox. Prospective, rigorous clinical trials are urgently needed to confirm the potential preventive and treatment effect of Chinese herbal formulas.

RESUMEN
Jujube (Zizyphus jujuba Mill.), a native small deciduous tree of China, is widely cultivated in China, Korea, India, Japan, Europe, and the United States (Chen et al. 2020). The fruit have been commonly consumed as healthy food supplements and traditional Chinese medicine for over 2000 years (Li et al. 2007). In August 2019, anthracnose-like leaf spot symptoms were observed on jujube plants in Xiaomenya Village, Jinan City, Shandong Province, China (36°27'39â³N, 117°3'13â³E), with over 30% leaf disease incidence. The spots were circular, sunken, brown in the center and with dark brown edges. As the spots enlarged and coalesced, it resulted in leaf perforation and early defoliation. Sometimes acervuli were observed on the lesions (Fig. S1a, b). To identify the causal agent, 20 diseased leaves were sampled, the margins of the lesions were cut into pieces (5 × 5 mm), sterilized and cultured following the protocol described previously (Wan et al. 2020) at 25 â for 5 days. Twelve monospore isolates showing identical colony morphology were obtained. Three representative isolates, JNZG11, JNZG311, JNZG313, were used for further study. When grown on PDA the colony color was initially white and then turned pale-gray to gray in 5-day-old cultures. On the reverse, colonies were brown-black with an orange pigmentation near the center. Aerial mycelium was cottony, dense, white to pale-gray. Conidia were hyaline, 1-celled, smooth-walled, subcylindrical, oblong, attenuated with slightly rounded ends, (11.1-) 12.7-13.3 (-17.8) ×(-4.4) 5.2-5.5 (-6.3) µm (n=50). Appressoria were dark-brown, oval or irregular, (7.3-) 8.6-9.2 (-9.8) ×(-5.1) 5.8-6.9 (-7.0) µm (n=50) (Fig. S1c-g). The morphology resembled those of Colletotrichum gloeosporioides species complex (Cannon et al. 2012). For accurate identification, the sequences of the ribosomal internal transcribed spacer (ITS), actin (ACT), ß-tub2 (TUB2), calmodulin (CAL), chitin synthase (CHS-1), and glyceraldehyde-3phosphate dehydrogenase (GAPDH) of the 3 isolates were sequenced (Weir et al. 2012), and deposited into GenBank (Accession Nos. see Table 1). The six loci (ITS, GAPDH, ACT, CHS-1, CAL, and TUB2) were concatenated and the aligned sequences (1904 bp) were 99.7% homologous to ex-type C. siamense ICMP18578. The sequences of 38 Colletotrichum species (44 isolates) were downloaded from GenBank for phylogenetic analyses. In the maximum likelihood phylogenetic tree generated, the highest log likelihood was -8798.90 and the three isolates were all in the C. siamense clade (bootstrap support 94 %) (Fig. S2). To complete Koch's postulates, 60 healthy, mature jujube leaves on 12 branches (5 leaves per branch) (variety 'Zhongqiuhong') were inoculated with 20 µL of spore suspension (106 conidia/mL) or sterile water as a control. The branches were placed in sterile beakers containing a small amount of sterile water sealed with plastic wrap and maintained at 28 °C, 12 h light/dark. Five days after inoculation, all treated leaves showed the typical anthracnose symptom, similar to that observed in the field (Fig. S1h). The same fungus was re-isolated from the margins of the lesions using the aforementioned methods. Whereas no fungus were isolated from the controls. Previously, C. siamense has been reported to infect Z. mauritiana in China (Shu et al. 2020). To our knowledge, this is the first report of C. siamense causing anthracnose on Z. jujuba in China. This finding provides crucial information for the effective management of this disease.
RESUMEN
Background: This study aimed to identify use of various treatments and their association with the use of antibiotics and patient reported clinical recovery in Chinese adults with acute cough. Methods: An online survey recruiting people who had recently experienced cough was conducted. Their sociodemographic, clinical characteristics, treatments received and their perceived changes in symptoms were collected. Factors influencing avoidance of antibiotics and improvement in symptoms were explored. Results: A total of 22,787 adults with recent acute cough completed the questionnaire, covering all 34 province-level administrative units in China. Most respondents were male (68.0%), young (89.4%, aged 18-45), educated to university/degree or postgraduate level (44.6%), with a median cough severity of 6/10 on a numerical rating scale. Nearly half of the participants (46.4%) reported using antibiotics, among which 93.1% were for presumed upper respiratory tract infections (URTIs). Pharmacies (48.8%) were the most common source of antibiotics. Fewer patients took antibiotics after taking CHM (14.9%), compared to those who started with home remedies (18.0%), or allopathic non-antibiotic medication (25.0%). Antibiotics, allopathic non-antibiotic medications, CHM and home remedies were all perceived beneficial in relieving cough. Conclusions: Chinese adult responders report use of a considerable variety of treatments alone or in combination for acute cough. Patient-reported clinical recovery was similar regardless of treatment. There is likely a high proportion of inappropriate use of antibiotics for treatment of simple acute cough. As the majority of respondents did not use antibiotics as a first-line, and use of CHM was associated with relief of cough symptoms and reduction in the use of antibiotics, this presents an important opportunity for prudent antibiotic stewardship in China.
RESUMEN
This paper makes an interpretation of the collection Acupuncture: how to improve the evidence base published by BMJ & BMJ Open. Studies show that the quality of randomized controlled trial (RCT) of acupuncture is low, and multivariable Meta-regression analysis fails to confirm most factors commonly believed to influence the effect of acupuncture. The methodological challenges in design and conduct of RCT in acupuncture were analyzed, and a consensus on how to design high-quality acupuncture RCT was developed. The number of acupuncture systematic reviews was huge but the evidence was underused in clinical practice and health policy, and a large number of western clinical practice guidelines recommended acupuncture therapy, but the usefulness of recommendations needed to be improved. In view of the problems in clinical research on acupuncture mentioned in this collection, combined with the analysis of the purpose of clinical research on acupuncture, perspectives, study types, as well as the relationship between evidence and clinical decision-making, a five-stage study paradigm of clinical research on acupuncture is proposed.

OBJECTIVE@#To observe the effect of Tiaoqi Jieyu (regulating qi and relieving depression) acupuncture on the clinical symptoms of treatment-resistant depression (TRD), and to explore the relationship between the acupuncture pain sensitivity and symptom's improvement.@*METHODS@#A total of 78 patients with TRD were randomly divided into an observation group (39 cases, 3 cases dropped off) and a control group (39 cases, 4 cases dropped off). The patients in the control group were treated with medications according to the treatment plan of psychiatrists (at least one medication was 5-hydroxytryptamine reuptake inhibitor). On the basis of the control group, the patients in the observation group were treated with Tiaoqi Jieyu acupuncture, and Baihui (GV 20), Yintang (GV 24+), Yanglingquan (GB 34), Taichong (LR 3), Hegu (LI 4), Neiguan (PC 6), Yinlingquan (SP 9) and Zusanli (ST 36), etc. were selected. The acupuncture was given three times a week. Both groups were treated for 8 weeks. After 8-week treatment, the response rate of Hamilton depression scale-24 (HAMD-24) score after was evaluated in the two groups. The scores of HAMD-24 and Hamilton anxiety scale (HAMA) were compared between the two groups before treatment, after 4, 8-week treatment and 12 weeks after treatment (follow-up). After the first treatment and 8-week treatment, the visual analogue scale (VAS) score in the observation group was evaluated, and the correlation between VAS score after the first treatment and HAMD-24 score before treatment, between VAS score after the first treatment and the course of disease in the observation group was analyzed, and the correlation between difference of VAS after 8-week treatment and after the first treatment and difference of HAMD-24 score before treatment and after 8-week treatment was analyzed.@*RESULTS@#After 8-week treatment, the response rate of HAMD-24 score in the observation group was 52.8% (19/36), higher than 17.1% (6/35) in the control group (P<0.001). Compared before treatment, the scores of HAMD-24 and HAMA in the two groups were decreased after 4-week treatment, 8-week treatment and in follow-up (P<0.05), and those in the observation group were superior to the control group (P<0.05). After 8-week treatment, the acupuncture pain VAS score in the observation group was (5.28±2.13) points, which was higher than (3.33±1.62) points after the first treatment (P<0.001). There was a negative correlation between VAS score after the first treatment and HAMD-24 score before treatment in the observation group (r =-0.486, P=0.003); there was no correlation between acupuncture pain VAS score after the first treatment and the course of disease in the observation group (P>0.05). After 8-week treatment, there was a positive correlation between the difference of VAS score and the difference of HAMD-24 score in the observation group (r =0.514, P=0.001).@*CONCLUSION@#Tiaoqi Jieyu acupuncture could improve the depression and anxiety in patients with TRD, and the symptom's improvement is related to the recovery of acupuncture pain sensitivity.

To optimize the extraction process of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair by network pharmacology combined with analytic hierarchy process(AHP)-entropy weight method and multi-index orthogonal test. The potential active components and targets of Chuanxiong Rhizoma-Gastrodiae Rhizoma were screened by network pharmacology and molecular docking, and the process evaluation indexes were determined with reference to the Chinese Pharmacopoeia(2020 edition). The core components of Chuanxiong Rhizoma-Gastrodiae Rhizoma were determined as gastrodin, parishin B, parishin C, parishin E, ferulic acid, and 3-butylphthalide. With the extraction volume of each indicator and yield of dry extract as comprehensive evaluation indicators, the extraction conditions were optimized by the AHP-entropy weight method and orthogonal test as the ethanol volume of 50%, the solid-liquid ratio of 1∶8(g·mL~(-1)), extraction for three times, and 1.5 h each time. Through network pharmacology and molecular docking, the process evaluation index was determined, and the optimized process was stable and reproducible for the extraction of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair, which could provide reference for in-depth research.
