Skin Conductance-Based Acupoint and Non-Acupoint Recognition Using Machine Learning.

Acupoints (APs) prove to have positive effects on disease diagnosis and treatment, while intelligent techniques for the automatic detection of APs are not yet mature, making them more dependent on manual positioning. In this paper, we realize the skin conductance-based APs and non-APs recognition with machine learning, which could assist in APs detection and localization in clinical practice. Firstly, we collect skin conductance of traditional Five-Shu Point and their corresponding non-APs with wearable sensors, establishing a dataset containing over 36000 samples of 12 different AP types. Then, electrical features are extracted from the time domain, frequency domain, and nonlinear perspective respectively, following which typical machine learning algorithms (SVM, RF, KNN, NB, and XGBoost) are demonstrated to recognize APs and non-APs. The results demonstrate XGBoost with the best precision of 66.38%. Moreover, we also quantify the impacts of the differences among AP types and individuals, and propose a pairwise feature generation method to weaken the impacts on recognition precision. By using generated pairwise features, the recognition precision could be improved by 7.17%. The research systematically realizes the automatic recognition of APs and non-APs, and is conducive to pushing forward the intelligent development of APs and Traditional Chinese Medicine theories.

Combination Therapy of Bone Marrow Mesenchymal Stem Cell Transplantation and Electroacupuncture for the Repair of Intrauterine Adhesions in Rats: Mechanisms and Functional Recovery.

Transplantation of bone marrow mesenchymal stem cells (BMSCs) has demonstrated promising clinical utility in the treatment of endometrial injury and the restoration of fertility. However, since the efficacy of BMSCs after transplantation is not stable, it is very important to find effective ways to enhance the utilisation of BMSCs. Electroacupuncture (EA) has some positive effects on the chemotaxis of stem cells and diseases related to uterine injury. In this study, we established the intrauterine adhesion (IUA) model of the Sprague-Dawley rat using lipopolysaccharide infection and mechanical scratching. Phosphate-buffered saline, BMSCs alone, and BMSCs combined with EA were randomly administered to the rats. Fluorescent cell labelling showed the migration of transplanted BMSCs. H&E staining, Masson staining, Western blot, immunohistochemistry, ELISA, and qRT-PCR were utilised to detect changes in endometrial morphology and expressions of endometrial receptivity-related factors, endometrial pro-inflammatory factors, and fibrosis factors. Finally, we conducted a fertility test to measure the recovery of uterine function. The results showed that EA promoted transplanted BMSCs to migrate into the injured uterus by activating the SDF-1/CXCR4 axis. Endometrial morphology showed the most significant improvement in the BMSC + EA group. The expressions of endometrial pro-inflammatory factors and fibrosis indexes in the BMSC + EA group were lower than those in the model and BMSC groups. Further studies revealed that the expression of endometrial receptivity-related factors and the number of embryos implanted on day 8 of gestation increased in the BMSC + EA group compared with the model group and the BMSC group.

Epicoccum sorghinum Causing Leaf Spot on Polygonatum cyrtonema in China.

Polygonatum cyrtonema Hua (family Asparagaceae) is a traditional Chinese medicinal plant that is widely cultivated in various parts of China, including Hunan Province. In summer 2022, a leaf spot disease was observed in 10% of the P. cyrtonema plants (Huang jing) in 18 hectares of this crop in the Hongjiang District (27°18'4″N, 110°11'1″E) of Hunan Province. The initial symptoms of the disease were brown spots on young leaves, and adjacent tissues gradually changed from green to yellow. The entire leaf then became yellow, withered, and eventually exhibited a thn and black appearance. In total, 12 diseased plants from four sampling sites (three plants per site) were collected for laboratory analysis to address the concerns of P. cyrtonema growers. Symptomatic leaf samples were selected, and the leaf fragments containing infected parts of the plants were disinfected with 75% ethanol for 1 min, then immersed in 2.5% hypochlorite for 45 s. After disinfection, symptomatic leaf samples were rinsed three times with sterile water, placed on potato saccharose agar containing 50 µg/ml kanamycin and incubated at 25°C for 2 days. Subsequently, 12 fungal isolates were isolated from various leaf samples through hyphal tip transferring. Ten of the 12 fungal isolates had similar morphological features, and one of them (isolate hjh) was used as the representative isolate for the study. With a growth rate of 6.3 mm per day, its white colonies transformed into red concentric rings in five days; they gradually became black after 10 days of growth. The chlamydospores were round (4.0-9.9 × 3.1-9.3 µm, n = 30), whereas the conidia were ovate (8.0-12.1 × 3.2-6.5 µm, n = 30). The morphological features of the isolate hjh were similar to the features of Epicoccum spp. (Aveskamp et al. 2010). The internal transcribed spacer (ITS) region (including the partial ITS1 sequence and the 5.8S and ITS2 complete sequences), ß-tubulin (tub) gene, and large subunit (LSU) rRNA gene, were amplified from the isolate hjh using the primer pairs ITS5/ITS4, Bt2a/Bt2b, and LROR/LR5, respectively (Taguiam et al. 2021). BLASTn analysis showed that the ITS (OR253745), tub (OR253764), and LSU (OR253746) sequences generated from the isolate hjh were 98-99% similar to the sequences of E. sorghinum strains CBS 179.80 and CBS 627.68. Subsequently, the ITS, tub, and LSU sequences were combined using Sequence Matrix software; phylogenetic analysis via Bayesian and maximum likelihood methods (Vaidya et al. 2011; Li et al. 2021) classified the isolate hjh into the E. sorghinum clade. To fulfill Koch's postulates, pathogenicity tests were conducted on healthy (lesion-free and disease-free) 2-year-old P. cyrtonema plants. Three healthy plants were inoculated by spraying whole plant until run-off with a spore suspension of the isolate hjh (1 × 106 conidia/ml); Three other healthy plants were sprayed with sterile water as controls. The inoculated plants were incubated in a growth chamber at 25 ± 2°C with 85% humidity for 28 days(Chen et al. 2021). Leaves from the inoculated plants gradually became brown within 15 days. Finally, the plants died 28 days after inoculation. The control plants showed no symptoms throughout the experimental period. Isolates (isolate hjh1, hjh2 and hjh3) that were reisolated from the inoculated plants exhibited morphologically similar characteristics and molecularly identical to the original isolate hjh. To our knowledge, this is the first report of E. sorghinum causing leaf spot disease on P. cyrtonema. The results of this study may facilitate the production of P. cyrtonema in China.

Biology of Callistethus plagiicollis (Coleoptera: Scarabaeoidea: Rutelinae) and comparative morphology of its larvae.

Larvae of the beetle subfamily Rutelinae are poorly described in the literature. Notably, the morphology of the larvae of Callistethus plagiicollis Fairmaire has not previously been analyzed. Here, we report for the first time that these larvae feed on the tubers and roots of Gastrodia elata Blume, an important traditional Chinese herbal medicine, which causes a reduction in the yield and economic value of G. elata. We employed scanning electron microscopy and light microscopy to investigate the morphology and occurrence regularity of egg, larvae, pupae, and adult specimens of C. plagiicollis collected from the G. elata planting base in Guizhou Province, China, with a focus on the ultrastructure of mature larvae. The results revealed one generation of C. plagiicollis per year in the study area and three instar stages of larvae. Mature larvae were identified by the following characteristics: raster without palidia with a large number of hamate setae, antennal apex containing seven sensilla basiconica, larval haptomerum containing eight sensilla styloconica and four enlarged heli, and seven longitudinally arranged stridulatory teeth on the stipes of the maxilla. The combination of scanning electron and light microscopy effectively revealed the difference between membranous and sclerotized structures, ensuring accurate identification of C. plagiicollis larvae. By determining the feeding characteristics and occurrence regularity of C. plagiicollis, this study has implications for improved pest management in G. elata crops. RESEARCH HIGHLIGHTS: We identified C. plagiicollis as a new pest of G. elata, a traditional Chinese medicine Scanning electron and light microscopy were combined to analyze the morphology of the mature larvae of C. plagiicollis for the first time We determined the feeding characteristics and occurrence regularity of C. plagiicollis, which can be used to develop effective pest management strategies.

Acupuncture for pain and pain-related disability in deep infiltrating endometriosis.

Objectives: To evaluate the efficacy of acupuncture in relieving symptoms (dysmenorrhea, dyspareunia, pelvic pain and dyschezia) intensity, improving functional disability, reducing the number of days per months of dysmenorrhea, the frequency and the efficacy of analgesic use in deep infiltrating endometriosis (DIE). The safety profile was also evaluated. Methods: The study sample was 34 patients with DIE; for 2 months (T-2, T-1) the women recorded diary notes on the numbers of days of menstruation, the presence, intensity, and disability related to dysmenorrhea, dyspareunia, pelvic pain, and dyschezia. They then received a total of 15 acupuncture treatments over 6 months (T1-T6; once a week for 12 weeks, then once a month for 3 months). Results: Dysmenorrhea intensity was decreased during treatment. A decrease of at least 50% in number of days of dysmenorrhea, and a decrease in moderate-to-severe disability starting from T1 to T6 was recorded for 58.6% of patients. Dyspareunia intensity steadily decreased starting at T2; the percentage of women with moderate-to-severe disability declined from 73.3% at T-2, to 36.9% at T3, T4, and T5. A decrease in pelvic pain score was noted starting at T1; the percentage of disability decreased from 83.3% at T-2 to 33.3% at T3 and T6. The intensity of dyschezia decreased from T-2 to T3 and T4 and then increased slightly. Analgesic drug use was lower during treatment and its efficacy appeared to be greater. Conclusions: The limitations notwithstanding our study-findings show that acupuncture was safe and effective in reducing pain intensity and symptoms-related disability. Larger-scale studies are needed to compare acupuncture and pharmacotherapy for endometriosis-related pain.

Investigating the Mechanism of Chufan Yishen Formula in Treating Depression through Network Pharmacology and Experimental Verification.

Objective: To investigate the antidepressant effect and potential mechanism of the Chufan Yishen Formula (CFYS) through network pharmacology, molecular docking, and experimental verification. Methods: The active ingredients and their target genes of CFYS were identified through Traditional Chinese Medicine Systems Pharmacology (TCMSP) and TCM-ID. We obtained the differentially expressed genes in patients with depression from the GEO database and screened out the genes intersecting with the target genes of CFYS to construct the PPI network. The key pathways were selected through STRING and KEGG. Then, molecular docking and experimental verification were performed. Results: A total of 113 effective components and 195 target genes were obtained. After intersecting the target genes with the differentially expressed genes in patients with depression, we obtained 37 differential target genes, among which HMOX1, VEGFA, etc., were the key genes. After enriching the differential target genes by KEGG, we found that the "chemical carcinogenesis-reactive oxygen species" pathway was the key pathway for the CFYS antidepressant effect. Besides, VEGFA might be a key marker for depression. Experimental verification found that CFYS could significantly improve the behavioral indicators of rats with depression models, including improving the antioxidant enzyme activity and increasing VEGFA levels. The results are consistent with the network pharmacology analysis. Conclusions: CFYS treatment for depression is a multicomponent, multitarget, and multipathway complex process, which may mainly exert an antidepressant effect by improving the neuron antioxidant stress response and regulating VEGFA levels.

Effects of traditional Chinese medicine-assisted intervention on improving postpartum lactation: A systematic review and meta-analysis.

Importance: Breast milk is the safest food for infants and has many psychological and physical benefits for infants and mothers. However, problems encountered during the breastfeeding process can reduce postpartum women's willingness to breastfeed. Lactation and engorgement may be improved through Traditional Chinese Medicine auxiliary therapy. However, the overall efficacy of various Traditional Chinese Medicine auxiliary therapies and the relevant meridians and acupuncture points for treating breast milk deficiency remain unclear. Objective: To investigate Traditional Chinese Medicine auxiliary therapy's effectiveness and acupoints for postpartum women who experience problems during the breastfeeding process. Methods: Data were sourced from Embase, Web of Science, CINAHL, Cochrane, CNKI, PubMed, and the Airiti Library Central Register of Controlled Trials and Clinical Trials from the database inception to October 2022. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Main outcome measures: The primary outcomes were overall efficiency, prolactin level, milk volume, and breast engorgement in postpartum women with lactation deficiency after-assisted therapies and the correlation between meridian points and milk secretion. Results: A total of 1,516 studies were initially identified, and 357 articles were assessed. In the final analysis, 20 studies were included, covering various Traditional Chinese Medicine therapies (acupuncture, acupressure, scrapping, moxibustion cupping, etc.) to stimulate relative acupoints without any acupoint stimulation. The overall efficiency (odds ratio [OR] = 14.17, 95% confidence interval [CI] = 6.49 to 30.92), prolactin level (standardized mean difference [SMD] = 0.36, 95% CI = 0.074 to 0.64), improvement of milk volume (SMD = 0.94, 95% CI = 0.59 to 1.29), reduction of engorgement level (OR= 18, 95% CI = 8.34 to 38.82) demonstrated that Traditional Chinese Medicine therapies can effectively improve lactation and breast fullness, thereby helping patients with breast milk deficiency. The most common acupuncture points used to treat agalactia were classified as the Stomach Meridian, Small Intestine Meridian, and Conception Vessel, with the common acupoints CV17: Danzhong, ST18: Rugen, SI1: Shaoze, ST36: Zusanli, and ST16: Yingchuang. Conclusion: Adjuvant Traditional Chinese Medicine therapy can improve lactation and breast engorgement, thereby increasing the willingness to breastfeed. Clinical Finding: 1. The best time for Traditional Chinese Medicine acupoint intervention for breast deficiency treatment is within 24 h 2. The most effective acupuncture points for improving milk deficiency and bloating pain are ST18: Rugen, ST16: Yingchuang, ST36: Zusanli, SI1: Shaoze, CV17: Danzhong. 3. Traditional Chinese Medicine is non-invasive and effective techniques such as scraping, cupping, acupressure and ear peas. 4. Traditional Chinese Medicine can be combined with other different acupuncture points according to the different constitutions of post-partum women. Breast acupressure, ear acupuncture, scrapping, cupping, and moxibustion are noninvasive treatments that can effectively help patients during lactation, and their clinical practice should be considered and widely promoted.

Development and testing of a post competency scale for traditional Chinese medicine physicians undergoing standardized training.

Objective: To develop and test a post competency scale for traditional Chinese medicine (TCM) physicians undergoing standardized training to provide an applicable tool for scientific evaluation. Methods: Based on literature analysis, behavioral event interviews, and expert consultations, measurement questions were formulated and the initial scale was designed. A questionnaire survey was conducted from July 2022 to May 2023 among TCM physicians undergoing standardized training in China. The rationality of the scale was confirmed through item purification, factor analysis, and tests of reliability and validity. Results: The post competency scale consisted of three dimensions (TCM fundamentals and research abilities, TCM thinking and skill abilities, and personal traits and communication abilities) with 21 items. Exploratory factor analysis identified three common factors, accounting for a cumulative variance contribution rate of 62.165%. Confirmatory factor analysis demonstrated that the fit indices of the three-factor model fell within a relatively ideal level. The Cronbach's alpha coefficient of the scale was 0.885. Through convergent validity analysis, the standardized loading coefficients of the 21 items were >0.5, and the average extracted variance (AVE) of the three factors was also >0.5. Moreover, the square roots of the AVE values for each dimension exceeded the correlation coefficients between it and the other dimensions. Conclusions: The findings suggest that the post competency scale of TCM physicians undergoing standardized training can provide a reliable scientific basis for training and assessment within China.

A Data Mining Study for Analysis of Acupoint Selection and Combinations in Acupuncture Treatment of Carpal Tunnel Syndrome.

Background: Carpal tunnel syndrome (CTS) is the most prevalent upper limb compressive neuropathy. A considerable number of clinical trials and meta-analyses have provided evidence supporting the effectiveness of acupuncture in treating CTS. Nevertheless, the ideal choice of acupoints remains ambiguous. Objective: A data mining analysis was conducted with the objective of determining the most effective acupoint combinations and selection for CTS. Methods: A search was conducted across seven Chinese and English electronic bibliographic databases spanning from their inception to March 2023. Selected were clinical trials that evaluated the efficacy of acupuncture therapy for CTS, with or without randomised controlled methods. Data extraction mainly included acupoint prescriptions. Information such as first author, study design and study setting were also extracted. The principal outcomes comprised the clinical manifestations linked to CTS. Statistical descriptions were generated using Excel 2019. The analysis of association rules was conducted using SPSS Modeler 18.0. Using SPSS Statistics 26.0, exploratory factor analysis and cluster analysis were conducted. Results: 142 trials (including 86 RCTs and 56 non RCTs) were identified, and 193 groups of effective prescriptions involving 68 acupoints were extracted. The most frequently used acupoints were Da-ling (PC7), Nei-guan (PC6), He-gu (LI4), Wai-guan (TE5), and Yang-xi (LI5). The most frequently used meridians were the pericardial meridian and the large intestine meridian. The majority of special acupoints used were Five-shu points and Yuan-source points, with acupoints on the upper limbs being the most frequently used. The core acupoint groups were analyzed and 11 groups of association rules, 8 factors, and 5 effective cluster groups were obtained. Conclusion: The evidence-based acupoint selection and combinations of acupuncture therapy for carpal tunnel syndrome were provided by the findings of this study.

Shengu granules ameliorate ovariectomy-induced osteoporosis by the gut-bone-immune axis.

Introduction: Postmenopausal osteoporosis (PMOP) is a common chronic disease, and the loss of bone density and bone strength after menopause are its main symptoms. Effective treatments for PMOP are still uncertain, but Chinese medicine has some advantages in slowing down bone loss. Shengu granules are often used clinically to treat PMOP. It has been shown to be an effective prescription for the treatment of PMOP, and there is evidence that gut flora may play an important role. However, whether Shengu granules attenuate PMOP by modulating gut flora and related mechanisms remains unclear. Methods: In this study, we mainly examined the bone strength of the femur, the structure of the intestinal microbiota, SCFAs in the feces and the level of FOXP3 cells in the colon. To further learn about the inflammation response, the condition of the mucosa and the level of cytokines in the serum also included in the testing. In addition, to get the information of the protein expression, the protein expression of OPG and RANKL in the femur and the protein expression of ZO-1 and Occludin in the colon were taken into account. Results: The osteoporosis was significantly improved in the SG group compared with the OVX group, and the diversity of intestinal flora, the secretion level of SCFAs and the expression level of FOXP3 were significantly increased compared with the OVX group. In terms of inflammatory indicators, the intestinal inflammation scores of the SG group was significantly lower than those in the OVX group. Additionally, the serum expression levels of IL-10 and TGF-ß in the SG group were significantly increased compared with the OVX group, and the expression levels of IL-17 and TNF-α were significantly decreased compared with the OVX group. In terms of protein expression, the expression levels of ZO-1, Occluding and OPG were significantly increased in the SG group compared with the OVX group, and the expression level of RANKL was significantly decreased compared with the OVX group. Discussion: Shengu granules treatment can improve the imbalance of intestinal flora, increase the secretion of SCFAs and the expression of FOXP3, which reduces the inflammatory response and repairs the intestinal barrier, as well as regulates the expression of OPG/RANKL signaling axis. Overall, Shengu granules ameliorate ovariectomy-induced osteoporosis by the gut-bone-immune axis.

Chinmedomics: a potent tool for the evaluation of traditional Chinese medicine efficacy and identification of its active components.

As an important part of medical science, Traditional Chinese Medicine (TCM) attracts much public attention due to its multi-target and multi-pathway characteristics in treating diseases. However, the limitations of traditional research methods pose a dilemma for the evaluation of clinical efficacy, the discovery of active ingredients and the elucidation of the mechanism of action. Therefore, innovative approaches that are in line with the characteristics of TCM theory and clinical practice are urgently needed. Chinmendomics, a newly emerging strategy for evaluating the efficacy of TCM, is proposed. This strategy combines systems biology, serum pharmacochemistry of TCM and bioinformatics to evaluate the efficacy of TCM with a holistic view by accurately identifying syndrome biomarkers and monitoring their complex metabolic processes intervened by TCM, and finding the agents associated with the metabolic course of pharmacodynamic biomarkers by constructing a bioinformatics-based correlation network model to further reveal the interaction between agents and pharmacodynamic targets. In this article, we review the recent progress of Chinmedomics to promote its application in the modernisation and internationalisation of TCM.

Metabolomics-Based Effects of a Natural Product on Remyelination After Cerebral Ischemia Injury Via GABABR-pCREB-BDNF Pathway.

BACKGROUND: Yi-Qi-Tong-Luo Granules (YQTLs) is a natural compound of Traditional Chinese Medicine authorized by China Food and Drug Administration (CFDA). These granules are employed in the convalescent stage of cerebral infarction and render notable clinical efficacy. This study aims to uncover the underlying mechanisms of YQTLs on remyelination after cerebral ischemia injury. MATERIALS AND METHODS: We established cerebral ischemia model in rats using microsphere-induced multiple cerebral infarction (MCI). We evaluated the pharmacological effects of YQTLs on MCI rats, through Morri's water maze test, open field test, hematoxylin and eosin staining, and glycine silver immersion. We employed liquid chromatography mass spectrometry metabolomics to identify differential metabolites. Enzyme-linked immunosorbent assay was utilized to measure the release of neurotrophins, while immunofluorescence staining was used to assess oligodendrocyte precursor cells differences and myelin regeneration. We used Western blotting to validate the protein expression of remyelination-associated signaling pathways. RESULTS: YQTLs significantly improves cognitive function following cerebral ischemia injury. Pathological tissue staining revealed that YQTLs administration inhibits neuronal denaturation and neurofibrillary tangles. We identified 141 differential metabolites among the sham, MCI, and YQTLs-treated MCI groups. Among these metabolites, neurotransmitters were identified, and notably, gamma-aminobutyric acid (GABA) showed marked improvement in the YQTLs group. The induction of neurotrophins, such as brain-derived neurotrophic factor (BDNF) and PDGFAA, upregulation of olig2 and MBP expression, and promotion of remyelination were evident in YQTLs-treated MCI groups. Gamma-aminobutyric acid B receptors (GABABR), pERK/extracellular regulated MAP kinase, pAKT/protein kinase B, and pCREB/cAMP response element-binding were upregulated following YQTLs treatment. CONCLUSION: YQTLs enhance the binding of GABA to GABABR, thereby activating the pCREB/BDNF signaling pathway, which in turn increases the expression of downstream myelin-associated proteins and promotes remyelination and cognitive function.

Electroacupuncture suppresses neuronal ferroptosis to relieve chronic neuropathic pain.

Growing evidence supports the analgesic efficacy of electroacupuncture (EA) in managing chronic neuropathic pain (NP) in both patients and NP models induced by peripheral nerve injury. However, the underlying mechanisms remain incompletely understood. Ferroptosis, a novel form of programmed cell death, has been found to be activated during NP development, while EA has shown potential in promoting neurological recovery following acute cerebral injury by targeting ferroptosis. In this study, to investigate the detailed mechanism underlying EA intervention on NP, male Sprague-Dawley rats with chronic constriction injury (CCI)-induced NP model received EA treatment at acupoints ST36 and GV20 for 14 days. Results demonstrated that EA effectively attenuated CCI-induced pain hypersensitivity and mitigated neuron damage and loss in the spinal cord of NP rats. Moreover, EA reversed the oxidative stress-mediated spinal ferroptosis phenotype by upregulating reduced expression of xCT, glutathione peroxidase 4 (GPX4), ferritin heavy chain (FTH1) and superoxide dismutase (SOD) levels, and downregulating increased expression of acyl-CoA synthetase long-chain family member 4 (ACSL4), malondialdehyde levels and iron overload. Furthermore, EA increased the immunofluorescence co-staining of GPX4 in neurons cells of the spinal cord of CCI rats. Mechanistic analysis unveiled that the inhibition of antioxidant pathway of Nrf2 signalling via its specific inhibitor, ML385, significantly countered EA's protective effect against neuronal ferroptosis in NP rats while marginally diminishing its analgesic effect. These findings suggest that EA treatment at acupoints ST36 and GV20 may protect against NP by inhibiting neuronal ferroptosis in the spinal cord, partially through the activation of Nrf2 signalling.

[Expert consensus on integrated traditional Chinese and western medicine diagnosis and treatment for osteoporotic fractures].

Osteoporotic fractures represent the most severe complications of osteoporosis,characterized by insidious onset,high mortality and disability rates,and a steadily increasing incidence,imposing a significant socioeconomic burden. Western medicine has advantages in diagnosis and surgical interventions,while traditional Chinese medicine excels in holistic management and the restoration of bodily equilibrium. The integration of both traditional Chinese medicine (TCM) and western medicine emerges as an effective therapeutic strategy for osteoporotic fractures. In order to propagate the concept of integrated diagnosis and treatment,foster the advancement of integrated medical techniques for osteoporotic fractures,and establish standardized and normative protocols for disease prevention,diagnosis,and treatment,a consensus expert group,led by Geriatric Branch of Chinese Geriatrics Society,the Young Osteoporosis Group of Orthopedics Branch of Chinese Medical Association,Osteoporosis Group of Orthopedics Branch of Chinese Physician Association,and Osteoporosis Professional Committee of the Shanghai Society of Integrated Traditional Chinese and Western Medicine,was established. This group engaged in deliberations and formulated the "Expert Consensus on Integrated Traditional Chinese and Western Medicine Diagnosis and Treatment of Osteoporotic Fractures" elucidating the concept of integrated medicine and offering recommendations in the domains of prevention,diagnosis,and treatment,with the aspiration of ameliorating the prognosis of osteoporotic fractures and enhancing the quality of life for these patients.

Effectiveness and safety of auricular acupuncture on adjuvant analgesia in patients with total knee arthroplasty: a randomized sham-controlled trial.

Objective: This study aimed to evaluate the effectiveness and safety of auricular acupuncture (AA) on postoperative analgesia, the degree of postoperative nausea, and the effect of inflammation after total knee arthroplasty (TKA). Methods: This was a single-center, placebo-controlled, randomized clinical trial. In total, 96 patients were randomly divided into an AA group with an indwelling intradermal needle (n = 48) and a sham auricular acupuncture (SAA) group with a non-penetrating placebo needle (n = 48). Intra-spinal anesthesia was adopted in both groups during surgery, and an epidural analgesic pump was implanted after surgery for 48 h. The primary outcome was the post-surgery visual analog score (VAS) of resting and movement states (at 6, 12 h and 1, 2, 3, 5, and 7 days). The secondary outcomes included additional doses of analgesic injection during the treatment, C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), and white blood cell (WBC) count on the 1st, 3rd, and 7th day after the operation, nausea on the 1st, 2nd, and 3rd day after the operation, the Hospital for Special Surgery Knee Score (HSS) on the 2nd and 12th week after the operation, and adverse events. Results: The VAS in the AA group at 6 h, 12 h, 2, 3, and 5 days after surgery were lower than those of the SAA group (p < 0.05). Among the secondary outcomes, the total dose of additional analgesic injection after surgery in the AA group was lower than that in the SAA group (p < 0.05). The serum CRP on the 1st day after operation in the AA group was lower than that in the SAA group (p < 0.05). The degree of nausea on 2nd day after surgery in the AA group was lower than that in the SAA group (p < 0.05). There was no significant difference in other outcomes (p > 0.05). Conclusion: In this study, AA was shown to be an effective and safe complementary and alternative therapy for pain relief after TKA, which was able to reduce the total postoperative dose of additional painkillers, decrease serum CRP 1 day after surgery, and improve the degree of postoperative nausea.

Using the right design controls for acupuncture trials: Methodological rigor and validity in research.

Acupuncture treatment can be defined as a medical procedure with an acupuncture needle at acupoints. Establishing suitable control settings is essential, based on the target elements of the acupuncture therapy. In order to properly design a clinical trial or an experiment, a control group must be established. Here, we overview the significance of the control group and its limitations in acupuncture research. Clinical trials have employed a variety of study designs and controls for acupuncture treatment in order to compare the effects of actual treatments with control groups that include no treatment or treatment as usual, sham acupuncture at true acupoints, real acupuncture at non-acupoints, and sham acupuncture at non-acupoints. In order to determine the point-specificity of acupuncture, real acupuncture at non-acupoints should be taken into consideration, whereas sham acupuncture at the same true acupoints should be used to determine the needling-specific effect of acupuncture. It is crucial to choose the optimum control for acupuncture treatments depending on the study's main goal and to interpret the results in accordance with the research design.

Sporoderm-broken spores of Ganoderma lucidum modulate hepatoblastoma malignancy by regulating RACK1-mediated autophagy and tumour immunity.

Hepatoblastoma (HB), a primary liver tumour, is notorious for its high metastatic potential and poor prognosis. Ganoderma lucidum, an edible mushroom species utilized in traditional Chinese medicine for addressing various tumour types, presents an intriguing avenue for HB treatment. However, the effectiveness of G. lucidum in managing HB and its underlying molecular mechanism necessitates further exploration. Standard in vitro assays were conducted to evaluate the impact of sporoderm-broken spores of G. lucidum (SBSGL) on the malignant characteristics of HB cells. The mechanism of SBSGL in treating HB and its tumour immunomodulatory effects were explored and validated by various experiments, including immunoprecipitation, Western blotting, mRFP-GFP-LC3 adenovirus transfection and co-localization analysis, as well as verified with in vivo experiments in this regard. The results showed that SBSGL effectively inhibited the malignant traits of HB cells and suppressed the O-GlcNAcylation of RACK1, thereby reducing its expression. In addition, SBSGL inhibited immune checkpoints and regulated cytokines. In conclusion, SBSGL had immunomodulatory effects and regulated the malignancy and autophagy of HB by regulating the O-GlcNAcylation of RACK1. These findings suggest that SBSGL holds promise as a potential anticancer drug for HB treatment.

Dietary therapy of the herbal porridge improves the symptoms of functional dyspepsia: A randomized, double-blind, placebo-controlled, clinical trial.

This study (ISRCTN17174559) aimed to explore the efficacy and safety of a kind of herbal porridge (Hou Gu Mi Xi) on the clinical symptoms of functional dyspepsia (FD). This was a single-center, single-dose, prospective, double-blind, randomized controlled trial involving 64 participants with FD (35 cases and 29 controls) for 2 months of intervention and 1 month of follow-up. The 7-point Global Overall Symptom Scale (GOSS), 36-Item Short Form Survey (SF-36), and other indicators were assessed at baseline (day 0), at days 15, 30, and 60 of treatment, and at follow-up 1 month after the end of the intervention. Many participants with FD achieved remission of their epigastric symptoms at follow-up on the 90th day after treatment with herbal porridge compared to the placebo group (45.71% vs. 20.69%, p = .036). Furthermore, herbal porridge appeared to be effective in improving the quality of life of participants with FD, which was reflected in the rising SF-36 scores for physical role, bodily pain, emotional role, and mental health. Although adverse events were reported, there was no overall difference in the number of adverse events between the two groups (p = .578). Herbal porridge is another effective and safe method for improving the symptoms and quality of life in patients with FD.

[Role of mitochondrial dynamics in diabetic cardiomyopathy and regulatory mechanisms].

Cardiovascular complications are the leading cause of death in diabetic patients. Among them, diabetic cardiomyopathy (DCM) is a type of specific cardiomyopathy excluding myocardial damage caused by hypertension and coronary heart disease. It is characterized by abnormal metabolism of cardiomyocytes and gradual decline of cardiac function. The clinical manifestations of DCM are impaired diastolic function in early stage and impaired systolic function in late stage. Eventually it developed into heart failure. Mitochondria are the main organelles that provide energy in cardiomyocytes. Mitochondrial dynamics refers to the dynamic process of mitochondrial fusion and fission, which is an important approach for mitochondrial quality control. Mitochondrial dynamics plays a crucial role in maintaining mitochondrial homeostasis and cardiac function. The proteins that regulate mitochondrial fission are mainly Drp1 and its receptors, Fis1, MFF, MiD49 and MiD51. The protein that performs mitochondrial outer membrane fusion is Mfn1/2, and the inner membrane fusion protein is Opa1. This paper reviews recent progress on mitochondrial dynamics in DCM. The main contents are as follows: mitochondrial dynamics imbalance in both type 1 and 2 DCM is manifested as increased fission and inhibited fusion. The molecular mechanism of the former is mainly associated with up-regulated Drp1 and down-regulated Opa1, while the molecular mechanism of the latter is mainly associated with up-regulated Drp1 and down-regulated Mfn1/2. Increased mitochondrial fission and inhibited fusion can lead to mitochondrial dysfunction and promote the development of DCM. The active ingredients of the traditional Chinese medicine such as punicalagin, paeonol and endogenous substance melatonin can improve mitochondrial function and alleviate the symptoms of DCM by inhibiting mitochondrial fission or promoting mitochondrial fusion. This article is helpful to further understand the role and mechanism of mitochondrial dynamics in DCM, and provide new treatment methods and intervention strategies for clinical DCM patients based on mitochondrial dynamics.
