Global trends of acupuncture clinical research on analgesia from 2010 to 2023: a bibliometric and visualization analysis.

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.

MDSCs in bone metastasis: Mechanisms and therapeutic potential.

Bone metastasis (BM) is a frequent complication associated with advanced cancer that significantly increases patient mortality. Myeloid-derived suppressor cells (MDSCs) play a pivotal role in BM progression by promoting angiogenesis, inhibiting immune responses, and inducing osteoclastogenesis. MDSCs induce immunosuppression through diverse mechanisms, including the generation of reactive oxygen species, nitric oxide, and immunosuppressive cytokines. Within the bone metastasis niche (BMN), MDSCs engage in intricate interactions with tumor, stromal, and bone cells, thereby establishing a complex regulatory network. The biological activities and functions of MDSCs are regulated by the microenvironment within BMN. Conversely, MDSCs actively contribute to microenvironmental regulation, thereby promoting BM development. A comprehensive understanding of the indispensable role played by MDSCs in BM is imperative for the development of novel therapeutic strategies. This review highlights the involvement of MDSCs in BM development, their regulatory mechanisms, and their potential as viable therapeutic targets.

Hovenia dulcis: a Chinese medicine that plays an essential role in alcohol-associated liver disease.

Globally, alcohol-associated liver disease (ALD) has become an increased burden for society. Disulfirams, Benzodiazepines (BZDs), and corticosteroids are commonly used to treat ALD. However, the occurrence of side effects such as hepatotoxicity and dependence, impedes the achievement of desirable and optimal therapeutic efficacy. Therefore, there is an urgent need for more effective and safer treatments. Hovenia dulcis is an herbal medicine promoting alcohol removal clearance, lipid-lowering, anti-inflammatory, and hepatoprotective properties. Hovenia dulcis has a variety of chemical components such as dihydromyricetin, quercetin and beta-sitosterol, which can affect ALD through multiple pathways, including ethanol metabolism, immune response, hepatic fibrosis, oxidative stress, autophagy, lipid metabolism, and intestinal barrier, suggesting its promising role in the treatment of ALD. Thus, this work aims to comprehensively review the chemical composition of Hovenia dulcis and the molecular mechanisms involved in the process of ALD treatment.

Extensive targeted metabolomics analysis reveals the identification of major metabolites, antioxidants, and disease-resistant active pharmaceutical components in Camellia tuberculata (Camellia L.) seeds.

Sect. tuberculata plant belongs to the Camellia genus and is named for the "tuberculiform protuberance on the surface of the ovary and fruit". It is a species of great ornamental value and potential medicinal value. However, little has been reported on the metabolites of C. tuberculata seeds. Therefore, this study was conducted to investigate the metabolites of C. tuberculata seeds based on UPLC/ESI-Q TRAP-MS/MS with extensively targeted metabolomics. A total of 1611 metabolites were identified, including 107 alkaloids, 276 amino acids and derivatives, 283 flavonoids, 86 lignans and coumarins, 181 lipids, 68 nucleotides and derivatives, 101 organic acids, 190 phenolic acids, 10 quinones, 4 steroids, 17 tannins, 111 terpenoids, and 177 other metabolites. We compared the different metabolites in seeds between HKH, ZM, ZY, and LY. The 1311 identified different metabolites were classified into three categories. Sixty-three overlapping significant different metabolites were found, of which lignans and coumarins accounted for the largest proportion. The differentially accumulated metabolites were enriched in different metabolic pathways between HKH vs. LY, HKH vs. ZM, HKH vs. ZY, LY vs. ZY, ZM vs. LY and ZM vs. ZY, with the most abundant metabolic pathways being 4, 2, 4, 7, 7 and 5, respectively (p < 0.05). Moreover, among the top 20 metabolites in each subgroup comparison in terms of difference multiplicity 7, 8 and 13. ZM and ZY had the highest phenolic acid content. Ninety-six disease-resistant metabolites and 48 major traditional Chinese medicine agents were identified based on seven diseases. The results of this study will not only lead to a more comprehensive and in-depth understanding of the metabolic properties of C. tuberculata seeds, but also provide a scientific basis for the excavation and further development of its medicinal value.

6-O-angeloylplenolin inhibits osteoclastogenesis in vitro via suppressing c-Src/NF-κB/NFATc1 pathways and ameliorates bone resorption in collagen-induced arthritis mouse model.

One of the effective therapeutic strategies to treat rheumatoid arthritis (RA)-related bone resorption is to target excessive activation of osteoclasts. We discovered that 6-O-angeloylplenolin (6-OAP), a pseudoguaianolide from Euphorbia thymifolia Linn widely used for the treatment of RA in traditional Chinese medicine, could inhibit RANKL-induced osteoclastogenesis and bone resorption in both RAW264.7 cells and BMMs from 1 µM and protect a collagen-induced arthritis (CIA) mouse model from bone destruction in vivo. The severity of arthritis and bone erosion observed in paw joints and the femurs of the CIA model were attenuated by 6-OAP administered at both dosages (1 or 5 mg/kg, i.g.). BMD, Tb.N and BV/TV were also improved by 6-OAP treatment. Histological analysis and TRAP staining of femurs further confirmed the protective effects of 6-OAP on bone erosion, which is mainly due to reduced osteoclasts. Molecular docking indicated that c-Src might be a target of 6-OAP and phosphorylation of c-Src was suppressed by 6-OAP treatment. CETSA and SPR assay further confirmed the potential interaction between 6-OAP and c-Src. Three signaling molecules downstream of c-Src that are vital to the differentiation and function of osteoclasts, NF-κB, c-Fos and NFATc1, were also suppressed by 6-OAP in vitro. In summary, the results demonstrated that the function of c-Src was disrupted by 6-OAP, which led to the suppression of downstream signaling vital to osteoclast differentiation and function. In conclusion, 6-OAP has the potential to be further developed for the treatment of RA-related bone erosion.

Aucubin Promotes Osteogenic Differentiation and Facilitates Bone Formation through the lncRNA-H19 Driven Wnt/ß-Catenin Signaling Regulatory Axis.

Objectives: Traditional Chinese medicine Cortex Eucommiae has been used to treat bone fracture for hundreds of years, which exerts a significant improvement in fracture healing. Aucubin, a derivative isolated from Cortex Eucommiae, has been demonstrated to possess anti-inflammatory, immunoregulatory, and antioxidative potential. In the present study, our aim was to explore its function in bone regeneration and elucidate the underlying mechanism. Materials and Methods: The effects of Aucubin on osteoblast and osteoclast were examined in mouse bone marrow-derived mesenchymal stem cells (BM-MSCs) and RAW 264.7 cells, respectively. Moreover, the lncRNA H19 and Wnt/ß-catenin signaling were detected by qPCR examination, western blotting, and luciferase activity assays. Using the femur fracture mice model, the in vivo effect of Aucubin on bone formation was monitored by X-ray, micro-CT, histomorphometry, and immunohistochemistry staining. Results: In the present study, Aucubin was found to significantly promote osteogenic differentiation in vitro and stimulated bone formation in vivo. Regarding to the underlying mechanism, H19 was found to be obviously upregulated by Aucubin in MSCs and thus induced the activation of Wnt/ß-catenin signaling. Moreover, H19 knockdown partially reversed the Aucubin-induced osteogenic differentiation and successfully suppressed the activation of Wnt/ß-catenin signaling. We therefore suggested that Aucubin induced the activation of Wnt/ß-catenin signaling through promoting H19 expression. Conclusion: Our results demonstrated that Aucubin promoted osteogenesis in vitro and facilitated fracture healing in vivo through the H19-Wnt/ß-catenin regulatory axis.

Role of phosphate in microalgal-bacterial symbiosis system treating wastewater containing heavy metals.

Phosphorus is one of the important factors to successfully establish the microalgal-bacterial symbiosis (MABS) system. The migration and transformation of phosphorus can occur in various ways, and the effects of phosphate on the MABS system facing environmental impacts like heavy metal stress are often ignored. This study investigated the roles of phosphate on the response of the MABS system to zinc ion (Zn2+). The results showed that the pollutant removal effect in the MABS system was significantly reduced, and microbial growth and activity were inhibited with the presence of Zn2+. When phosphate and Zn2+ coexisted, the inhibition effects of pollutants removal and microbial growth rate were mitigated compared to that of only with the presence of Zn2+, with the increasing rates of 28.3% for total nitrogen removal, 48.9% for chemical oxygen demand removal, 78.3% for chlorophyll-a concentration, and 13.3% for volatile suspended solids concentration. When phosphate was subsequently supplemented in the MABS system after adding Zn2+, both pollutants removal efficiency and microbial growth and activity were not recovered. Thus, the inhibition effect of Zn2+ on the MABS system was irreversible. Further analysis showed that Zn2+ preferentially combined with phosphate could form chemical precipitate, which reduced the fixation of MABS system for Zn2+ through extracellular adsorption and intracellular uptake. Under Zn2+ stress, the succession of microbial communities occurred, and Parachlorella was more tolerant to Zn2+. This study revealed the comprehensive response mechanism of the co-effects of phosphate and Zn2+ on the MABS system, and provided some insights for the MABS system treating wastewater containing heavy metals, as well as migration and transformation of heavy metals in aquatic ecosystems.

Discrimination and prediction of Qingzhuan tea storage year using quantitative chemical profile combined with multivariate analysis: Advantages of MRMHR based targeted quantification metabolomics.

The duration of storage significantly influences the quality and market value of Qingzhuan tea (QZT). Herein, a high-resolution multiple reaction monitoring (MRMHR) quantitative method for markers of QZT storage year was developed. Quantitative data alongside multivariate analysis were employed to discriminate and predict the storage year of QZT. Furthermore, the content of the main biochemical ingredients, catechins and alkaloids, and free amino acids (FAA) were assessed for this purpose. The results show that targeted marker-based models exhibited superior discrimination and prediction performance among four datasets. The R2Xcum, R2Ycum and Q2cum of orthogonal projection to latent structure-discriminant analysis discrimination model were close to 1. The correlation coefficient (R2) and the root mean square error of prediction of the QZT storage year prediction model were 0.9906 and 0.63, respectively. This study provides valuable insights into tea storage quality and highlights the potential application of targeted markers in food quality evaluation.

Efficient remediation of di-(2-ethylhexyl) phthalate and plant-growth promotion with the application of a phosphate-solubilizing compound microbial agent.

The ecotoxic endocrine-disrupting chemical di-(2-ethylhexyl) phthalate (DEHP) is ubiquitous in agricultural soil, posing a serious threat to human health. Here, we report efficient soil-borne DEHP degradation and plant growth promotion by a microbial organic fertilizer GK-PPB prepared by combining a recycled garden waste-kitchen waste compost product with ternary compound microbial agent PPB-MA, composed of Penicillium oxalic MB08F, Pseudomonas simiae MB751, and Bacillus tequilensis MB05B. The combination of MB08F and MB751 provided synergistic phosphorus solubilization, and MB05B enhanced the DEHP degradation capacity of MB08F via bioemulsification. Under optimal conditions (25.70 °C and pH 7.62), PPB-MA achieved a 96.81 % degradation percentage for 1000 mg L-1 DEHP within 5 days. The degradation curve followed first-order kinetics with a half-life of 18.24 to 24.76 h. A complete mineralization pathway was constructed after identifying the degradation intermediates of 2H-labeled DEHP. Evaluation in Caenorhabditis elegans N2 showed that PPB-MA eliminated the ecological toxicity of DEHP. A pakchoi (Brassica chinensis L.) pot experiment demonstrated that GK-PPB promoted phosphorus solubilization and plant growth, reduced soil DEHP residue, and decreased DEHP accumulation in pakchoi, suggesting its potential practical utility in environmentally responsible and safe cultivation of vegetables.

High enrichment and sensitive measurement of oxytetracycline in tea drinks by thermosensitive magnetic molecular imprinting based magnetic solid phase extraction coupled with boron doped carbon dots.

As a typical kind of new pollutants, there are still some challenges in the rapid detection of antibiotics. In this work, a sensitive fluorescent probe based on boron-doped carbon dots (B-CDs) in combination with thermo-responsive magnetic molecularly imprinted polymers (T-MMIPs) was constructed for the detection of oxytetracycline (OTC) in tea drinks. T-MMIPs were designed, fabricated and employed to enrich OTC at trace level from tea drinks, and B-CDs were utilized as the fluorescent probe to detect the concentration of OTC. The proposed method exhibited good linear relationship with OTC concentration from 0.2 to 60 µg L-1 and the limit of detection was 0.1 µg L-1. The established method has been successfully validated with tea beverages. Present work was the first attempt application of T-MMIPs in combination with CDs in detection of OTC, and demonstrated that the proposed method endowed the detection of OTC with high selectivity, sensitivity, reliability and wide application prospect, meanwhile offered a new strategy for the method establishment of rapid and sensitive detection of trace antibiotics in food and other matrices.

Efficacy and safety of neoadjuvant sintilimab in combination with FLOT chemotherapy in patients with HER2-negative locally advanced gastric or gastroesophageal junction adenocarcinoma: an investigator-initiated, single-arm, open-label, phase II study.

BACKGROUND: The addition of immune checkpoint inhibitors to neoadjuvant chemotherapy in operable advanced gastric or gastroesophageal junction (G/GEJ) cancer aroused wide interest. This study was designed to assess the efficacy and safety of neoadjuvant sintilimab, a programmed cell death protein-1 (PD-1) inhibitor, in combination with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy for HER2-negative locally advanced G/GEJ cancer. METHODS: Eligible patients with clinical stage cT4 and/or cN+M0 G/GEJ cancer were enroled in this phase II study. Patients received neoadjuvant sintilimab (200 mg every 3 weeks) for three cycles plus FLOT (50 mg/m 2 docetaxel, 80 mg/m 2 oxaliplatin, 200 mg/m 2 calcium levofolinate, 2600 mg/m 2 5-fluorouracil every 2 weeks) for four cycles before surgery, followed by four cycles of adjuvant FLOT with same dosages after resection. The primary endpoint was the pathological complete response (pCR) rate. RESULTS: Thirty-two patients were enroled between August 2019 and September 2021, with a median follow-up of 34.8 (95% CI, 32.8-42.9) months. Thirty-two (100%) patients received neoadjuvant therapy, and 29 underwent surgery with an R0 resection rate of 93.1%. The pCR (TRG0) was achieved in 5 (17.2%; 95% CI, 5.8-35.8%) patients, and the major pathological response was 55.2%. Twenty-three (79.3%) patients had T downstaging, 21 (72.4%) had N downstaging, and 19 (65.5%) had overall TNM downstaging. Six (20.7%) patients experienced recurrence. Patients achieving pCR showed better event-free survival (EFS), disease-free survival (DFS), and overall survival (OS) than non-pCR. The estimated 3-year EFS rate, 3-year DFS rate, and 3-year OS rate were 71.4% (95% CI, 57.2-89.2%), 78.8% (95% CI, 65.1-95.5%), and 70.9% (95% CI, 54.8-91.6%), respectively. The objective response rate and disease control rate were 84.4% (95% CI, 68.3-93.1%) and 96.9% (95% CI, 84.3-99.5%), respectively. Twenty-five (86.2%) received adjuvant therapy. The main grade ≥3 treatment-related adverse events (TRAEs) were lymphopenia (34.4%), neutropenia (28.1%), and leukopenia (15.6%). no patients died from TRAE. The LDH level exhibited a better predictive value to pathological responses than PD-L1 and MSI status. CONCLUSIONS: The study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant sintilimab plus FLOT in HER2-negative locally advanced G/GEJ cancer, which suggested a potential therapeutic option for this population.

[Buyang Huanwu Decoction promotes arteriogenesis after hindlimb ischemia in mice by activating PDGF signaling pathway].

This study aims to investigate the effect of Buyang Huanwu Decoction on blood flow recovery and arteriogenesis after hindlimb ischemia in mice via the platelet-derived growth factor(PDGF) signaling pathway. Forty C57BL/6 mice were randomized into model(clean water, 10 mL·kg~(-1)·d~(-1)), beraprost sodium(positive control, 18 µg·kg~(-1)·d~(-1)), and low-, medium-, and high-dose(10, 20, and 40 g·kg~(-1)·d~(-1), respectively) Buyang Huanwu Decoction groups(n=8). The hindlimb ischemia model was established by femoral artery ligation. The mice were administrated with corresponding agents by gavage daily for 14 days after ligation. For laser Doppler perfusion imaging, the mice were anesthetized and measured under a Periscan PSI imager. The density of capillary and arterio-le in the ischemic gastrocnemius was measured using immunofluorescence staining of the frozen tissue sections. Western blot was employed to determine the expression of PDGF subunit B(PDGFB), phosphorylated mitogen extracellular kinase(p-MEK), MEK, phosphorylated extracellular signal-regulated kinase(p-ERK), and ERK. Real-time PCR was employed to determine the mRNA level of PDGFB. The Buyang Huanwu Decoction-containing serum was used to treat the vascular smooth muscle cells(VSMCs) in hypoxia at doses of 10% and 20%. The proliferation and migration of VSMCs was assessed in vitro. The results showed that compared with the model group, beraprost sodium and Buyang Huanwu Decoction enhanced the blood flow recovery, increased the capillary and arteriole density, and up-regulated the protein levels of PDGFB, p-MEK, p-ERK, and mRNA levels of PDGFB, with the medium-dose Buyang Huanwu Decoction demonstrating the most significant effect. The 10% Buyang Huanwu Decoction-containing serum enhanced the proliferation and migration of VSMCs. Our findings demonstrate that Buyang Huanwu Decoction up-regulates PDGFB transcription and activates PDGF signaling pathway to promote arteriogenesis and blood flow recovery in ischemic gastrocnemius.

Association between MTHFR C677T Gene Polymorphisms and the Efficacy of Vitamin Therapy in lowering Homocysteine Levels among Stroke Patients with Hyperhomocysteinemia.

BACKGROUND: The impact of the methylenetetrahydrofolate reductase (MTHFR) C677T mutation on the relationship between plasma homocysteine (Hcy) levels and stroke has been extensively studied and documented in previous study. However, it remains unclear whether the MTHFR C677T mutation can affect the response to Hcy lowering treatment in stroke patients with hyperhomocysteinemia (HHcy). Understanding the impact of genetic factors on treatment response can help optimize personalized treatment strategies for stroke patients with HHcy. We aimed to investigate the potential association between the MTHFR C677T gene polymorphisms and the effectiveness of Hcy lowering treatment using vitamin therapy in stroke patients with HHcy. METHODS: The MTHFR C677T genotype polymorphisms were identified using polymerase chain reaction-restriction fragment length polymorphism, and the distribution of three genotypes in the MTHFR C677T gene locus was compared. The treatment effects of Hcy lowering agents were compared among patients with different genotypes. RESULTS: Among the 320 stroke patients enrolled in the study, 258 (80.6%) were diagnosed with HHcy. Of these, 162 patients (Effective Group) responded well to the clinical Hcy lowering treatment, while 96 patients (Invalid Group) failed to achieve sufficient response even after taking combination supplements of folic acid, Vitamin B6, and methylcobalamin for one month. Significant differences were observed in terms of age (p < 0.001), hypertension (p = 0.034), dyslipidemia (p = 0.022), hyperuricemia (p = 0.013) and genotype distribution of MTHFR C677T gene polymorphism (p < 0.001) between the Invalid group and the Effective group. The multivariate regression analysis revealed that the T allele (odd rations [OR], 1.327; 95% confidence interval [CI], 1.114-1.580; p = 0.0015) was independently associated with an insufficient Hcy lowering treatment effect. Additionally, the TT genotype was independently associated with insufficient response in both the codominant model (OR, 1.645; 95% CI, 1.093-2.476; p = 0.017) and the recessive model (TT versus CC + CT; OR, 1.529; 95% CI, 1.145-2.042; p = 0.004). However, no relationship was observed between CT + TT genotypes and poor treatment effect in the dominate model. CONCLUSIONS: Our findings suggested that the TT genotype and T allele of MTHFR C677T polymorphism were independently associated with an insufficient Hcy lowering treatment effect in stroke patients with HHcy.

Comparative impact of exercise-based interventions for postpartum depression: A Bayesian network meta-analysis.

OBJECTIVE: The current study aimed to address and rank which exercise-based interventions are preferable to standard care/no therapy or another exercise intervention for postpartum depression (PPD) management and provide estimates for future definitive evidence. METHODS: The authors systematically searched PubMed, Embase, the Web of Science, PsycInfo, and ClinicalTrails.gov for randomized controlled trials (RCTs) on exercise-based interventions for PPD from their inception to May 9, 2023. Included were RCTs of exercise-based interventions for PPD with at least 4 weeks' duration. The pooled effects of intervention comparisons were generated by the Bayesian random-effects model, and the quality of evidence was evaluated by the Grading of Recommendations, Assessment, Development, and Evaluations framework. RESULTS: Twelve RCTs (1260 women; mean age, 20-35 years) comparing exercise-based interventions with usual care/no therapy were included. Exercise effectively treats depressive symptoms (standard mean difference [SMD], -0.81 [95% confidence interval (CI), -1.20 to -0.42], P < 0.001). Pram walking was significantly associated with a reduction of depressive symptoms during the postpartum period (SMD, -1.00 [95% CI, -2.60 to -0.10], P = 0.020), as well as yoga (SMD, -0.73 [95% CI, -1.84 to -0.43], P < 0.001) and supervised mixed exercise (SMD, -0.77 [95% CI, -1.67 to -0.01], P = 0.041) compared with usual care/no therapy. In indirect comparisons, pram walking (surface under the cumulative ranking curve, 58.9%) was better than yoga (SMD, -0.28 [95% CI, -1.86 to 1.22], P = 0.322) and supervised mixed exercise (SMD, -0.23 [95% CI, -1.59 to 1.12], P = 0.358). However, the difference was not statistically significant. The confidence in evidence was very low to moderate. CONCLUSION: In women with PPD, all commonly prescribed physical exercises were effective alternative or complementary treatments. However, pram walking may perform better in improving the symptoms of PPD.

Dendrobium nobile Lindl ameliorates learning and memory deficits in scopolamine-treated mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Dendrobium nobile Lindl (DNL), a valued time-honored herb, possesses immune-boosting and age-delaying properties, has been widely used to treat hyperglycemia and neurological diseases, and is probably a potential drug for improving learning and memory. Scopolamine (Scop), an antagonist for muscarinic receptors, potentially impairing intelligence and memory. AIM OF THE STUDY: This investigation aimed to assess the efficacy of DNL in alleviating scopolamine-induced cognitive deficits in mice and its mechanisms. MATERIALS AND METHODS: We utilized the open-field test, novel object recognition test (NOR), and Morris water maze test (MWM) to assess the potential of DNL in ameliorating learning and memory dysfunction caused by scopolamine in mice. Enzyme-linked immunosorbent assay (ELISA) was employed to measure Choline acetyltransferase (ChAT) content and Acetylcholinesterase (AChE) activities in the brain, and oxidative stress-related factors in the serum, including Malondialdehyde (MDA), Superoxide dismutase (SOD), and glutathione (GSH) content. RESULTS: Scopolamine injection significantly reduced the discrimination index of mice in the NOR test and impaired their performance in the MWM test, as demonstrated by longer escape latency, fewer target crossings, and less time spent in the target quadrant in the MWM. After 25 days of administration, DNL increased the discrimination index of the scopolamine-treated mice in the NOR test. DNL reduced the escape latency in the MWM test in the model mice. DNL increased the target crossing number and the percentage of time spent in the target quadrant in the MWM test. ELISA experiments indicated that DNL decreased the AChE activities, increased the ChAT activities, and modulated oxidative stress makers (GSH, SOD, and MDA) in scopolamine-induced mice. CONCLUSIONS: DNL may improve the learning and memory in mice treated with scopolamine, possibly by modulating oxidative stress and impaired cholinergic function.

Enhancing surgical precision: unveiling the impact of preoperative colonoscopy in anal fistula patients.

BACKGROUND: Anal fistula is a common benign anorectal disease that often requires surgical intervention for effective treatment. In recent years, preoperative colonoscopy as a diagnostic tool in patients with anal fistula has garnered increasing attention due to its potential clinical application value. By investigating underlying inflammatory bowel disease (IBD), polyps, and other abnormalities, preoperative colonoscopy can offer insights to refine surgical strategies and improve patient outcomes. METHODS: This retrospective study focused on 1796 patients with various benign anorectal diseases who underwent preoperative intestinal endoscopy and met surgical criteria within the preceding three years at the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine. Among these patients, 949 diagnosed with anal fistula comprised group A, while 847 patients without anal fistula were assigned to group B for comparison. The investigation encompassed an analysis of general patient information, endoscopic findings, polyp histopathology, distribution of bowel inflammation sites, and results of inflammatory bowel disease assessments between the two patient cohorts. A subgroup analysis was also conducted on 2275 anal fistula patients with no surgical contraindications. This subgroup was categorized into Group A (949 patients who underwent preoperative intestinal endoscopy) and Group C (1326 patients who did not undergo preoperative colonoscopy). The study compared the rates of detecting endoscopic lesions and IBD-related findings between the two subgroups. RESULTS: The study initially confirmed the comparability of general patient information between groups A and B. Notably, the abnormal detection rate in group A was significantly higher than in group B (P < 0.01). In terms of endoscopic findings, the anal fistula group (group A) exhibited higher rates of detecting bowel inflammation, inflammatory bowel disease, and polyps compared to the non-anal fistula group (group B) (P < 0.05). The distribution of inflammation locations indicated higher detection rates in the terminal ileum, ileocecal region, and ascending colon for group A compared to group B (P < 0.05). Although the incidence of IBD in group A was higher than in group B, this difference did not reach statistical significance (P > 0.05). Subsequently, the analysis of the subgroup (groups A and C) revealed a significant disparity in intestinal endoscopic detection rates (P < 0.01) and statistically significant differences in detecting IBD (P < 0.05) and Crohn's disease (P < 0.05) between the two anal fistula subgroups. CONCLUSIONS: The findings of this study underscore the substantial clinical value of preoperative colonoscopy in the comprehensive evaluation of patients with anal fistula. Preoperative colonoscopy aids in ruling out localized perianal lesions caused by underlying inflammatory bowel disease, thereby mitigating the likelihood of missed diagnoses and enhancing treatment outcomes. This research highlights the importance of incorporating preoperative colonoscopy as a valuable diagnostic tool in managing anal fistula patients.

[Meta-analysis and trial sequential analysis of Chaihuang Granules in treatment of upper respiratory tract infection in children].

This study aimed to evaluate the efficacy and safety of Chaihuang Granules in the treatment of upper respiratory tract infection in children. The databases such as CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, Web of Science, Chinese Clinical Trial Registry, and ClinicalTrials.gov were searched for randomized controlled trial(RCT) of Chaihuang Granules for the treatment of upper respiratory tract infection in children, and supplemented by manual searching of gray literature. Two investigators independently screened the literature, extracted data, and assessed the methodological quality. Meta-analysis was performed using RevMan 5.4 software, trial sequential analysis was conducted using TSA 0.9.5.10 Beta software, and evidence quality evaluation was carried out using GRADE profiler 3.6.1 software. Eighteen RCTs involving 2 459 patients(1 262 in the treatment group and 1 197 in the control group) were included. Meta-analysis showed that compared with conventional therapy alone, Chaihuang Granules significantly improved the total effective rate(RR=1.18, 95%CI[1.15, 1.22], P<0.000 01), reduced the disappearance time of symptoms/signs(MD=-1.39, 95%CI[-1.66,-1.12], P<0.000 01), improved cytokine levels(MD=-2.40, 95%CI[-3.80,-1.00], P=0.000 8), improved humoral immune levels(MD=0.75, 95%CI[0.60, 0.90], P<0.000 01), and reduced the recurrence rate(MD=-2.11, 95%CI[-2.98,-1.25], P<0.000 01). However, the incidence of adverse reactions was not increased(RR=0.94, 95%CI[0.59, 1.49], P=0.78). Subgroup analysis showed that:(1) both Chaihuang Granules used alone(RR=1.19, 95%CI[1.11, 1.27], P<0.000 01) and in combination with other therapies(RR=1.18, 95%CI[1.14, 1.22], P<0.000 01) effectively improved the total effective rate.(2) In terms of symptoms/signs disappearance time, Chaihuang Granules effectively reduced the duration of fever(MD=-1.18, 95%CI[-1.78,-0.58], P=0.000 1), cough with sputum(MD=-1.82, 95%CI[-2.38,-1.25], P<0.000 01), cough(MD=-1.31, 95%CI[-1.89,-0.74], P<0.000 01), sore throat(MD=-1.57, 95%CI[-2.25,-0.89], P<0.000 01), and lung rales(MD=-1.49, 95%CI[-2.06,-0.92], P<0.000 01).(3) Regarding cytokine levels, Chaihuang Gra-nules effectively improved the levels of interleukin(IL)-2(MD=-0.94, 95%CI[-1.16,-0.72], P<0.000 01), IL-6(MD=-4.71, 95%CI[-6.39,-3.03], P<0.000 01), and tumor necrosis factor-α(TNF-α)(MD=-2.07, 95%CI[-2.43,-1.71], P<0.000 01).(4) In terms of cellular immune levels, Chaihuang Granules effectively improved the levels of CD3~+(MD=4.11, 95%CI[1.53, 6.69], P=0.002), CD4~+(MD=4.21, 95%CI[1.69, 6.73], P=0.001), CD8~+(MD=-2.65, 95%CI[-3.93,-1.37], P<0.000 1), and CD4~+/CD8~+(MD=0.25, 95%CI[0.14, 0.37], P<0.000 1).(5) In terms of humoral immune levels, Chaihuang Granules effectively improved the levels of IgA(MD=0.44, 95%CI[0.23, 0.64], P<0.000 1), IgM(MD=0.31, 95%CI[0.15, 0.46], P=0.000 1), and IgG(MD=2.02, 95%CI[1.60, 2.43], P<0.000 01). Trial sequential analysis showed that the cumulative Z-curve of the total effective rate crossed the boundary value, further confirming its clinical efficacy. The GRADE evidence quality evaluation showed that the evidence quality of the above outcome indicators was low or very low, and the recommendation strength was weak. Compared to conventional therapy alone, Chaihuang Granules can effectively improve the total effective rate of treatment, alle-viate symptoms and signs of upper respiratory tract infection in children, improve inflammatory conditions, enhance immune function, and reduce the recurrence rate. Due to the limited quality of the included studies, high-quality RCT is still needed to provide evidence support for the above conclusions.

[Comparative study of purgative pharmacological effects and mechanisms of Moringa oleifera leaves and Rhei Radix et Rhizoma].

Moringa oleifera leaves are known for their "Virechana"(purgative) effect in Ayurvedic medicine in India. This study compared the purgative effects and mechanisms of M. oleifera leaves with the reference Rhei Radix et Rhizoma to establish a foundation for the further application of M. oleifera leaves in traditional Chinese medicine(TCM). Using network pharmacology and molecular docking methods, this study identified the material basis, common targets, and signaling pathways through which Rhei Radix et Rhizoma and M. oleifera leaves exerted their purgative pharmacological effects. A low-fiber diet-induced constipation mouse model was established to measure fecal parameters and small intestinal propulsion rate, and histological changes in the colon were observed using HE staining. Relative expression levels of relevant genes and target proteins were assessed using RT-qPCR and immunohistochemistry, respectively. The results showed that mapping the targets of Rhei Radix et Rhizoma and M. oleifera leaves onto the biological process network of constipation revealed close proximity, indicating that they may exert their therapeutic effects on constipation through similar biological processes. Molecular docking results indicated that compounds such as sennoside C and isoquercitrin could target serine/threonine protein kinases(AKT1) and mitogen-activated protein kinase 3(MAPK3), thereby affecting MAPK and calcium signaling pathways to promote defecation. Animal experiments demonstrated that both M. oleifera leaves and Rhei Radix et Rhizoma increased the number of fecal pellets and water content in constipated mice, improved small intestine motility, colon mucosal thickness, and muscle layer thickness, upregulated the gene expression levels of AKT1 and MAPK3 in the colon, and downregulated the expression of AQP3 protein. These findings suggest that M. oleifera leaves and Rhei Radix et Rhizoma share similarities in their therapeutic efficacy and mechanisms for treating constipation. Using Rhei Radix et Rhizoma as a reference can provide a better understanding of the characteristics of the "Virechana"(purgative) effect of M. oleifera leaves in TCM.

OBJECTIVES: To investigate the effect of "Tongdu Qishen" acupunctureï¼»dredging the Govern Vessel and normalizing mental activities, electroacupuncture (EA) of "Baihui" (GV20), "Yintang" (EX-HN3) and "Shuigou" (GV26) needlingï¼½on the learning-memory ability and the mechanism of ferroptosis in Alzheimer's disease (AD) mice. METHODS: Twenty-four male APPswe/PS1dE9 mice were randomly and equally divided into model group and EA group, and 12 normal C57BL/6 mice were used as the control group. In the EA group, EA (2 Hz/100 Hz, 20 min) was applied to GV20 and EX-HN3 in combination with manual acupuncture stimulation of GV26. The treatment was performed once a day, for a total of 28 days. The mice in the three groups were given the same fixation and grasping operation. Morris water maze swimming tests were used to assess the mice's learning-memory ability. Nissl staining and transmission electron microscopy were used to observe the morphological changes of neurons in the hippocampus. The activity of superoxide dismutase (SOD) in the hippocampus tissue was detected by superoxide anionic colorimetric assay kit (WST-1), and malondialdehyde (MDA) contents were detected by thiobarbituric acid (TBA) method. The expression levels of prostaglandin endoperoxide synthase 2 (ptgs2) and glutathione peroxidase 4 (GPX4) mRNA in the hippocampus were detected by fluorescent quantitative real-time PCR. RESULTS: Behavioral results showed that compared with the control group, the escape latencies at the 2nd, 3rd, 4th and 5th day of Morris water maze swimming test were significantly increased (P<0.05), and the swimming time in the original platform quadrant and the times of cros-sing the original platform were considerably decreased (P<0.05) in the model group. In comparison with the model group, the escape latencies at the 4th and 5th day were strikingly decreased (P<0.05), and the swimming time in the original platform quadrant and times of crossing the original platform significantly increased (P<0.05) in the EA group. Following modeling, the SOD activity and the expression of GPX4 mRNA were obviously down-regulated (P<0.05), and the content of MDA and the expression of ptgs2 mRNA significantly up-regulated (P<0.05) in the model group rele-vant to the control group. The SOD activity and the expression of GPX4 mRNA were apparently increased (P<0.05), and the content of MDA and the expression of ptgs2 mRNA remarkably down-regulated (P<0.05) in the EA group rele-vant to the model group. Histopathological and ultrastructural results showed scattered arrangement of cells, widened space among cells, reduction in the number of cells, and many shrunk of dissolved nucleoli, shrunking and incomplete mitochondria, and high membrane electron density in the hippocampus of the model group, which was relatively milder in the EA group. CONCLUSIONS: "Tongdu Qishen" acupuncture can improve the learning-memory ability of AD mice, which may be related to its functions in up-regulating SOD activity and GPX4 mRNA expression, and down-regulating MDA content and ptgs2 mRNA expression to reduce the lipid peroxidation in the process of ferroptosis.
