A method for accurate identification of Uyghur medicinal components based on Raman spectroscopy and multi-label deep learning.

Uyghur medicine is one of the four major ethnic medicines in China and is a component of traditional Chinese medicine. The intrinsic quality of Uyghur medicinal materials will directly affect the clinical efficacy of Uyghur medicinal preparations. However, in recent years, problems such as adulteration of Uyghur medicinal materials and foreign bodies with the same name still exist, so it is necessary to strengthen the quality control of Uyghur medicines to guarantee Uyghur medicinal efficacy. Identifying the components of Uyghur medicines can clarify the types of medicinal materials used, is a crucial step to realizing the quality control of Uyghur medicines, and is also an important step in screening the effective components of Uyghur medicines. Currently, the method of identifying the components of Uyghur medicines relies on manual detection, which has the problems of high toxicity of the unfolding agent, poor stability, high cost, low efficiency, etc. Therefore, this paper proposes a method based on Raman spectroscopy and multi-label deep learning model to construct a model Mix2Com for accurate identification of Uyghur medicine components. The experiments use computer-simulated mixtures as the dataset, introduce the Long Short-Term Memory Model (LSTM) and Attention mechanism to encode the Raman spectral data, use multiple parallel networks for decoding, and ultimately realize the macro parallel prediction of medicine components. The results show that the model is trained to achieve 90.76% accuracy, 99.41% precision, 95.42% recall value and 97.37% F1 score. Compared to the traditional XGBoost model, the method proposed in the experiment improves the accuracy by 49% and the recall value by 18%; compared with the DeepRaman model, the accuracy is improved by 9% and the recall value is improved by 14%. The method proposed in this paper provides a new solution for the accurate identification of Uyghur medicinal components. It helps to improve the quality standard of Uyghur medicinal materials, advance the research on screening of effective chemical components of Uyghur medicines and their action mechanisms, and then promote the modernization and development of Uyghur medicine.

Dihydroartemisinin alleviates erosive bone destruction by modifying local Treg cells in inflamed joints: A novel role in the treatment of rheumatoid arthritis.

Treg cell-based therapy has exhibited promising efficacy in combatting rheumatoid arthritis (RA). Dihydroartemisinin (DHA) exerts broad immunomodulatory effects across various diseases, with its recent spotlight on T-cell regulation in autoimmune conditions. The modulation of DHA on Treg cells and its therapeutic role in RA has yet to be fully elucidated. This study seeks to unveil the influence of DHA on Treg cells in RA and furnish innovative substantiation for the potential of DHA to ameliorate RA. To this end, we initially scrutinized the impact of DHA-modulated Treg cells on osteoclast (OC) formation in vitro using Treg cell-bone marrow-derived monocyte (BMM) coculture systems. Subsequently, employing the collagen-induced arthritis (CIA) rat model, we validated the efficacy of DHA and probed its influence on Treg cells in the spleen and popliteal lymph nodes (PLN). Finally, leveraging deep proteomic analysis with data-independent acquisition (DIA) and parallel accumulation-serial fragmentation (PASEF) technology, we found the alterations in the Treg cell proteome in PLN by proteomic analysis. Our findings indicate that DHA augmented suppressive Treg cells, thereby impeding OC formation in vitro. Consistently, DHA mitigated erosive joint destruction and osteoclastogenesis by replenishing splenic and joint-draining lymph node Treg cells in CIA rats. Notably, DHA induced alterations in the Treg cell proteome in PLN, manifesting distinct upregulation of alloantigen Col2a1 (Type II collagen alfa 1 chain) and CD8a (T-cell surface glycoprotein CD8 alpha chain) in Treg cells, signifying DHA's targeted modulation of Treg cells, rendering them more adept at sustaining immune tolerance and impeding bone erosion. These results unveil a novel facet of DHA in the treatment of RA.

Artemisia argyi extract subfraction exerts an antifungal effect against dermatophytes by disrupting mitochondrial morphology and function.

Artemisia argyi (A. argyi), a plant with a longstanding history as a raw material for traditional medicine and functional diets in Asia, has been used traditionally to bathe and soak feet for its disinfectant and itch-relieving properties. Despite its widespread use, scientific evidence validating the antifungal efficacy of A. argyi water extract (AAWE) against dermatophytes, particularly Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, remains limited. This study aimed to substantiate the scientific basis of the folkloric use of A. argyi by evaluating the antifungal effects and the underlying molecular mechanisms of its active subfraction against dermatophytes. The results indicated that AAWE exhibited excellent antifungal effects against the three aforementioned dermatophyte species. The subfraction AAWE6, isolated using D101 macroporous resin, emerged as the most potent subfraction. The minimum inhibitory concentrations (MICs) of AAWE6 against T. rubrum, M. gypseum, and T. mentagrophytes were 312.5, 312.5, and 625 µg·mL-1, respectively. Transmission electron microscopy (TEM) results and assays of enzymes linked to cell wall integrity and cell membrane function indicated that AAWE6 could penetrate the external protective barrier of T. rubrum, creating breaches ("small holes"), and disrupt the internal mitochondrial structure ("granary"). Furthermore, transcriptome data, quantitative real-time PCR (RT-qPCR), and biochemical assays corroborated the severe disruption of mitochondrial function, evidenced by inhibited tricarboxylic acid (TCA) cycle and energy metabolism. Additionally, chemical characterization and molecular docking analyses identified flavonoids, primarily eupatilin (131.16 ± 4.52 mg·g-1) and jaceosidin (4.17 ± 0.18 mg·g-1), as the active components of AAWE6. In conclusion, the subfraction AAWE6 from A. argyi exerts antifungal effects against dermatophytes by disrupting mitochondrial morphology and function. This research validates the traditional use of A. argyi and provides scientific support for its anti-dermatophytic applications, as recognized in the Chinese patent (No. ZL202111161301.9).

The FJQR Has Synergistic Effect with Fluoropyrimidine in the Maintenance Treatment for HER-2 Negative Gastric Cancer.

INTRODUCTION: Maintenance therapy aimed to strengthen the first-line chemotherapy and improve quality of life is needed for gastric cancer (GC). Currently, many clinical studies have confirmed the important role of fluoropyrimidine in the maintenance stage. Our team has created patented prescriptions "Fuzheng jiedu Quyu Method" recipe (FJQR), which was considered as an adjuvant therapeutic scheme (reduce toxicity and increase the efficacy of chemotherapy). This study aimed to evaluate the efficacy and safety of FJQR combined with fluoropyrimidine as a maintenance treatment in HER-2 negative GC patients. METHODS: We performed the analysis of 129 patients with HER-2 negative GC who entered the maintenance stage in our hospital and Tianjin Cancer Hospital between January 2018 and December 2020. Out of the 129 eligible patients, 64 were categorized into the maintenance treatment group with FJQR+fluoropyrimidine, and 65 patients were assigned to the control group if they received fluoropyrimidine alone. Capecitabine was orally 1000mg/m2, Qd, half an hour after meals, and FGQR was 15g Bid after capecitabine. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival (OS), overall remission rate (ORR), quality of Life (QOL), TCM syndrome and safety. RESULTS: The mPFS in the treatment group was significantly prolonged compared with the control group (6.3 vs. 5.0 months, p = 0.03), while the mOS was not substantially improved (11.4 vs. 10.5 months, p = 0.38). Gastrointestinal symptoms and pain became better in the treatment group. The number of distant metastatic organs, first-line chemotherapy cycles, and lymph node metastasis were independent risk predictors for PFS. Blood stasis syndrome may be the protective factor. In terms of safety, treatment-related adverse events (AEs) in the treatment group were relatively lighter, and the incidence of grade III-IV AEs could be significantly reduced. CONCLUSION: FJQR and fluoropyrimidine have synergistic effects as maintenance treatment in HER-2 negative GC, with good efficacy and safety.

Clinical Study of Deep Hyperthermia Combined with Computational Medicine of Platinum Chemotherapy in the Treatment of Ovarian Cancer.

Objective: Deep hyperthermia combined with platinum-based chemotherapy (DHCT) might lead to the development of better therapeutic strategy for patients with malignant tumor. This study aimed to analyze the computational medical differences in ovarian cancer patients treated with DHCT compared with platinum-based chemotherapy alone. Methods: 78 patients with advanced ovarian cancer admitted from November 2017 to November 2021 were randomly selected as subjects. Overall survival analysis and CA125 clinical efficiency evaluation were performed to explore the effect of DHCT on cis-platinum therapy. All patients were informed and consented, and approved by the hospital committee. The data were systematically analyzed by chi-squared test to analyze clinical effect and safety observation, and the Kaplan-Meier method and log-rank test were used for survival analysis. Results: Survival analysis showed that DHCT was strongly associated with improved overall survival (OS) in the platinum treatment of ovarian cancer patients (Hazard Ratio = 1.57, 95% CI: 0.93-2.44, P = .017). For ovarian cancer patients receiving lobaplatin treatment, DHCT could also elevate their survival (Hazard Ratio = 1.52, 95% CI :1.02-2.25, P = .013). The study also showed a statistically significant difference in clinical outcomes between the two groups (P < .001), and the opposite is true for adverse reactions. Conclusion: Our results suggest that DHCT is expected to be combined with platinum chemotherapy, which is helpful for the molecular classification of ovarian cancer patients. More studies are needed to further verified the clinical significance.

Clinical efficacy of Camrelizumab combined with first-line chemotherapy in extensive-stage small-cell lung cancer.

Objective: Exploring the clinical efficacy of camrelizumab in combination with first-line chemotherapy in patients with extensive-stage small-cell lung cancer (ES-SCLC). Methods: The clinical data of 35 patients with ES-SCLC who received camrelizumab combined with EC or EP regimen in First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from January 2020 to January 2023 were retrospectively analyzed. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were OS, ORR and DCR. SPSS 25.0 software was used for statistical analysis, Kaplan-Meier curve and Log-Rank test analysis, and survival curve was drawn. Results: The median PFS of 35 patients with SCLC was 7.4 months (95 % CI 6.75-9.81 months), .and the median OS was 12.5 months (95% CI,11.71-16.90 months). The ORR and DCR were 65.7 % and 74.3 %, respectively. Adverse events (AEs) were mainly concentrated in grade 1-2, and the probability of occurrence of grade 3 or above was low. Reactive Cutaneous Capillary Endothelial Proliferation (RCCEP) was the most common, followed by nausea &vomit and anemia. The other common AEs included abnormal thyroid function, decreased neutrophil count, skin rash and leucopenia. Conclusion: Camrelizumab in combination with first-line chemotherapy regimens prolonged OS and PFS in SCLC patients and showed efficacy and safety in real-world data.

A Mobile Health-Based Management for Patients with Limited Lung Function to Improve Treatment Outcomes and Quality of Life After Minimally Invasive Thoracoscopic Lobectomy.

Objective: Limited lung function is an independent risk factor for postoperative respiratory failure in non-small cell lung cancer (NSCLC) patients. In this study, we developed a mobile health-based management for NSCLC patients with limited lung function who were scheduled to receive lobectomy and evaluated its effects on the patient's pulmonary function and quality of life. Methods: A total of 60 NSCLC patients scheduled to receive minimally invasive thoracoscopic lobectomy were enrolled and then randomized into the traditional management group and the program management group, with 30 patients per group. Based on the WeChat mini program, a management software for patients with limited lung function was established, including two portals: the patient portal and the nurse one. The pain assessment was performed using the Visual Analog Scale (VAS) scores, the cough assessment using the Leicester Cough Questionnaire, and the quality-of-life assessment using the EORTC QLQ-30 at 1 day before surgery, 1 week, 2 weeks, 1 month, 6 months, or 12 months after surgery. Results: The program management group exhibited an increased PaO2 (96.68 ± 7.92 vs. 87.69 vs. 5.50; P = .018) concomitant with a declined PaCO2 (38.55 ± 2.79 vs. 40.65 ± 2.17; p = 0.034) at 12 months after surgery compared with the traditional management group. The VAS scores showed significant differences at 2 weeks after surgery between the traditional management (median: 2; range: 2-3) and program management (median: 2; range: 1-2) groups (P = .012). The scores of Leicester Cough Questionnaire showed remarkable differences at 12 months after surgery between the traditional management (20.00 ± 1.54) and program management (18.99 ± 2.08) groups (P = .036). The total scores of EORTC QLQ-30 showed notable differences at 12 months after surgery between the traditional management (83.05 ± 14.09) and program management (90.55 ± 11.32) groups (P = .027). Conclusion: The study demonstrated improved pulmonary function and a better quality of life conferred by the mobile health-based management based on WeChat mini program for NSCLC patients with limited lung function and undergoing thoracoscopic lobectomy in a long follow up.

TCMBank: bridges between the largest herbal medicines, chemical ingredients, target proteins, and associated diseases with intelligence text mining.

Traditional Chinese Medicine (TCM) has long been viewed as a precious source of modern drug discovery. AI-assisted drug discovery (AIDD) has been investigated extensively. However, there are still two challenges in applying AIDD to guide TCM drug discovery: the lack of a large amount of standardized TCM-related information and AIDD is prone to pathological failures in out-of-domain data. We have released TCM Database@Taiwan in 2011, and it has been widely disseminated and used. Now, we developed TCMBank, the largest systematic free TCM database, which is an extension of TCM Database@Taiwan. TCMBank contains 9192 herbs, 61 966 ingredients (unduplicated), 15 179 targets, 32 529 diseases, and their pairwise relationships. By integrating multiple data sources, TCMBank provides 3D structure information of ingredients and provides a standard list and detailed information on herbs, ingredients, targets and diseases. TCMBank has an intelligent document identification module that continuously adds TCM-related information retrieved from the literature in PubChem. In addition, driven by TCMBank big data, we developed an ensemble learning-based drug discovery protocol for identifying potential leads and drug repurposing. We take colorectal cancer and Alzheimer's disease as examples to demonstrate how to accelerate drug discovery by artificial intelligence. Using TCMBank, researchers can view literature-driven relationship mapping between herbs/ingredients and genes/diseases, allowing the understanding of molecular action mechanisms for ingredients and identification of new potentially effective treatments. TCMBank is available at https://TCMBank.CN/.

Comparative efficacy and safety of multiple acupuncture therapies for post stroke cognitive impairment: a network meta-analysis of randomized controlled trials.

Background: Acupuncture therapy has been widely used to treat post-stroke cognitive impairment (PSCI). However, acupuncture therapy includes multiple forms. Which acupuncture therapy provides the best treatment outcome for patients with PSCI remains controversial. Objective: We aimed to compare and evaluate the efficacy and safety of different acupuncture-related therapies for PSCI in an attempt to identify the best acupuncture therapies that can improve cognitive function and self-care in daily life for patients with PSCI, and bring new insights to clinical practice. Method: We searched eight databases including PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China Biomedical Literature Database (CBM), China Science and Technology Journal (VIP) database, China National Knowledge Infrastructure (CNKI) database, and Wan fang database to find randomized controlled trials (RCTs) of acupuncture-related therapies for PSCI from the inception of the database to January 2023. Two researchers independently assessed the risk of bias in the included studies and extracted the study data. Pairwise meta-analyzes for direct comparisons were performed using Rev. Man 5.4 software. Bayesian network meta-analysis (NMA) was performed using STATA 17.0 and R4.2.4 software. The quality of evidence from the included studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Adverse effects (AEs) associated with acupuncture therapy were collected by reading the full text of the included studies to assess the safety of acupuncture therapy. Results: A total of 62 RCTs (3 three-arm trials and 59 two-arm trials) involving 5,073 participants were included in this study. In the paired meta-analysis, most acupuncture-related therapies had a positive effect on cognitive function and self-care of daily living in patients with PSCI compared with cognitive training. Bayesian NMA results suggested that ophthalmic acupuncture plus cognitive training (79.7%) was the best acupuncture therapy for improving MMSE scores, with scalp acupuncture plus cognitive training ranking as the second (73.7%). The MoCA results suggested that warm acupuncture plus cognitive training (86.5%) was the best acupuncture therapy. In terms of improvement in daily living self-care, scalp acupuncture plus body acupuncture (87.5%) was the best acupuncture therapy for improving MBI scores. The most common minor AEs included subcutaneous hematoma, dizziness, sleepiness, and pallor. Conclusion: According to our Bayesian NMA results, ophthalmic acupuncture plus cognitive training and warm acupuncture plus cognitive training were the most effective acupuncture treatments for improving cognitive function, while scalp acupuncture plus body acupuncture was the best acupuncture treatment for improving the performance of self-care in daily life in patients with PSCI. No serious adverse effects were found in the included studies, and acupuncture treatment appears to be safe and reliable. However, due to the low methodological quality of the included studies, our findings need to be treated with caution. High-quality studies are urgently needed to validate our findings.

The clinical application of atorvastatin in patients with small-cell lung cancer with dyslipidemia.

BACKGROUND: Various experimental studies demonstrated that atorvastatin exerted additive effects with anticancer drugs to impair tumor growth, delay relapse, and prolong survival time in lung cancer. However, it is indistinct whether there are survival benefits of atorvastatin in the treatment of small-cell lung cancer (SCLC) patients with dyslipidemia. Therefore, this study aimed to evaluate the efficacy and safety of atorvastatin plus first-line standard chemotherapy in SCLC combined dyslipidemia. METHODS: This was a retrospective analysis of 91 eligible SCLC patients with dyslipidemia registered at the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from October 2018 to October 2022. SCLC patients with confirmed dyslipidemia were assigned to the treatment group to receive atorvastatin plus first-line standard chemotherapy (n = 45) or to the control group to accept chemotherapy (n = 46) until disease progression or unmanageable toxicity occurred. The clinicopathological parameters and survival data were collected and analyzed. Univariate and multivariate analyses were performed to investigate the prognostic significance of SCLC. The median progression-free survival (mPFS) was considered to be the pivotal symbol as the primary endpoint. The second endpoints were recognized as the median overall survival (mOS) and toxicity. RESULTS: In the total of 91 enrolled patients, the curative effect can be evaluated in all patients. Research results showed that atorvastatin added to first-line standard chemotherapy was associated with a significant improvement in survival (mPFS: 7.4 vs 6.8 months, P = 0.031; mOS: 14.7 vs 13.2 months, P = 0.002). CONCLUSION: Atorvastatin added to first-line standard chemotherapy achieved prospective efficacy and manageable safety in SCLC combined dyslipidemia.

Multi-omic approach characterises the neuroprotective role of retromer in regulating lysosomal health.

Retromer controls cellular homeostasis through regulating integral membrane protein sorting and transport and by controlling maturation of the endo-lysosomal network. Retromer dysfunction, which is linked to neurodegenerative disorders including Parkinson's and Alzheimer's diseases, manifests in complex cellular phenotypes, though the precise nature of this dysfunction, and its relation to neurodegeneration, remain unclear. Here, we perform an integrated multi-omics approach to provide precise insight into the impact of Retromer dysfunction on endo-lysosomal health and homeostasis within a human neuroglioma cell model. We quantify widespread changes to the lysosomal proteome, indicative of broad lysosomal dysfunction and inefficient autophagic lysosome reformation, coupled with a reconfigured cell surface proteome and secretome reflective of increased lysosomal exocytosis. Through this global proteomic approach and parallel transcriptomic analysis, we provide a holistic view of Retromer function in regulating lysosomal homeostasis and emphasise its role in neuroprotection.

The Zinc Transporter SLC39A10 Plays an Essential Role in Embryonic Hematopoiesis.

The role of zinc in hematopoiesis is currently unclear. Here, SLC39A10 (ZIP10) is identified as a key zinc transporter in hematopoiesis. The results show that in zebrafish, Slc39a10 is a key regulator of the response to zinc deficiency. Surprisingly, both slc39a10 mutant zebrafish and hematopoietic Slc39a10-deficient mice develop a more severe form of impaired hematopoiesis than animals lacking transferrin receptor 1, a well-characterized iron gatekeeper, indicating that zinc plays a larger role than iron in hematopoiesis, at least in early hematopoietic stem cells (HSCs). Furthermore, it is shown that loss of Slc39a10 causes zinc deficiency in fetal HSCs, which in turn leads to DNA damage, apoptosis, and G1 cell cycle arrest. Notably, zinc supplementation largely restores colony formation in HSCs derived from hematopoietic Slc39a10-deficient mice. In addition, inhibiting necroptosis partially restores hematopoiesis in mouse HSCs, providing mechanistic insights into the requirement for zinc in mediating hematopoiesis. Together, these findings indicate that SLC39A10 safeguards hematopoiesis by protecting against zinc deficiency-induced necroptosis, thus providing compelling evidence that SLC39A10 and zinc homeostasis promote the development of fetal HSCs. Moreover, these results suggest that SLC39A10 may serve as a novel therapeutic target for treating anemia and zinc deficiency-related disorders.

Higher ETCOc predicts longer phototherapy treatment in neonatal hyperbilirubinemia.

Objective: This study aimed to evaluate the predictive performance of end-tidal carbon monoxide corrected to ambient carbon monoxide (ETCOc) values phototherapy in neonates with significant hyperbilirubinemia. Methods: A prospective study was conducted on neonates with significant hyperbilirubinemia who received phototherapy between 3 and 7 days of life. The breath ETCOc and serum total bilirubin of the recruited infants were measured on admission. Results: The mean ETCOc at admission in 103 neonates with significant hyperbilirubinemia was 1.70 ppm. The neonates were categorized into two groups: phototherapy duration ≤72 h (n = 87) and >72 h (n = 16) groups. Infants who received phototherapy for >72 h had significantly higher ETCOc (2.45 vs. 1.60, P = 0.001). The cutoff value of ETCOc on admission for predicting longer phototherapy duration was 2.4 ppm, with a sensitivity of 62.5% and specificity of 88.5%, yielding a 50% positive predictive value and a 92.7% negative predictive value. Conclusion: ETCOc on admission can help predict the duration of phototherapy in neonates with hyperbilirubinemia, facilitate clinicians to judge disease severity, and make clinical communication easier and more efficient.

Effects of traditional Chinese mind-body exercises on older adults with cognitive impairment: A systematic review and meta-analysis.

Objective: To determine the effectiveness of traditional Chinese mind-body exercises in improving cognition, memory, and executive function in older adults with cognitive impairment. Data sources: Relevant English and Chinese language studies published until September 14th, 2022 were retrieved from PubMed, Web of Science, Cochrane Library, Embase, CINAHL, WAN FANG DATA, VIP Information, CNKI, and SinoMed databases. Review methods: Randomized controlled trials assessing traditional Chinese mind-body exercises (Tai Chi, Baduanjin, Qigong, Mind-Body Therapies, and Yijinjing) in older adults with cognitive impairment were included. Two researchers independently identified eligible studies and extracted data. A risk-of-bias assessment was performed using the Cochrane Risk of Bias Tool. Results: This study included 15 randomized controlled trials (1,127 participants) from China, Thailand and American. Most studies had a high risk of bias in the blinding of participants and researchers, one study had a high risk of bias in the random sequence generation and two studies had a high risk of bias in the incomplete outcome data. Compared with conventional therapy alone, traditional Chinese mind-body exercises significantly improved global cognitive function (p < 0.00001), and Baduanjin could improve the global cognitive function (p < 0.00001), memory function (p < 0.0001), and executive function (p < 0.0001) outcomes after treatment, and significantly improved some dimensional scores on the auditory verbal learning test after treatment (p = 0.04). Conclusion: Compared with conventional therapy, traditional Chinese mind-body exercises (Tai Chi, Baduanjin, and Qigong) significantly improved global cognitive function, and Baduanjin could improve global cognitive function, memory function, and executive function in older adults with cognitive impairment.

Research progress on the immunomodulatory mechanism of acupuncture in tumor immune microenvironment.

With the constantly deeper understanding of individualized precision therapy, immunotherapy is increasingly developed and personalized. The tumor immune microenvironment (TIME) mainly consists of infiltrating immune cells, neuroendocrine cells, extracellular matrix, lymphatic vessel network, etc. It is the internal environment basis for the survival and development of tumor cells. As a characteristic treatment of traditional Chinese medicine, acupuncture has shown potentially beneficial impacts on TIME. The currently available information demonstrated that acupuncture could regulate the state of immunosuppression through a range of pathways. An effective way to understand the mechanisms of action of acupuncture was to analyze the response following treatment of the immune system. This research reviewed the mechanisms of acupuncture regulating tumor immunological status based on innate and adaptive immunity.

miR-330 targeting BCO2 is involved in carotenoid metabolism to regulate skin pigmentation in rainbow trout (Oncorhynchus mykiss).

BACKGROUND: MicroRNAs (miRNAs) play a critical role in regulating skin pigmentation. As a key economic trait, skin color directly affects the market value of rainbow trout (Oncorhynchus mykiss), however, the regulatory mechanism of most miRNAs in fish skin color is still unclear. RESULTS: In this study, the full-length cDNA sequence of ß-carotene oxygenase 2 (BCO2, a key regulator of carotenoid metabolism) from the rainbow trout was obtained using rapid-amplification of cDNA ends (RACE) technology, and qRT-PCR was used to investigate the differential expression of miR-330 and BCO2 in 14 developmental stages and 13 tissues between wild-type rainbow trout (WTrt) and yellow mutant rainbow trout (YMrt). Additionally, the function of miR-330 was verified by overexpression and silencing in vitro and in vivo. The results showed that the complete cDNA sequence of BCO2 was 2057 bp with a 1707 bp ORF, encoding a 568 amino acid protein having a molecular weight of 64.07 kD. Sequence alignment revealed that higher conservation of BCO2 protein amongst fishes than amongst other vertebrates, which was further confirmed by phylogenetic analysis. The analysis of spatial and temporal expression patterns suggested that BCO2 and miR-330 were abundantly expressed from fertilized-stage to multi-cell as well as in the dorsal and ventral skin of WTrt and YMrt, and their expression patterns were opposite in most of the same periods and tissues. In vitro, luciferase reporter assay confirmed that BCO2 was a direct target of miR-330, and transfection of miR-330 mimics into rainbow trout liver cells resulted in a decrease in the expression of BCO2; conversely, miR-330 inhibitor had the opposite effect to the miR-330 mimics. In vivo, miR-330 agomir significantly decreased BCO2 expression in dorsal skin, tail fin, and liver. Furthermore, overexpression of miR-330 could suppress cell proliferation and induce apoptosis. CONCLUSION: Our results showed that miR-330 is involved in the regulation of skin pigmentation in rainbow trout by targeting BCO2 and shows its promise as a potential molecular target to assist the selection of rainbow trout with better skin color patterns.

Acupuncture treatment vs. cognitive rehabilitation for post-stroke cognitive impairment: A systematic review and meta-analysis of randomized controlled trials.

Background: Cognitive impairment is one of the common sequelae after stroke, which not only hinders the recovery of patients but also increases the financial burden on families. In the absence of effective therapeutic measures, acupuncture treatment has been widely used in China to treat post-stroke cognitive impairment (PSCI), but the specific efficacy is unclear. Therefore, this review aimed to evaluate the true efficacy of acupuncture treatment in patients with PSCI. Methods: We searched eight databases [PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China Biomedical Literature Database (CBM), China Science and Technology Journal (VIP) database, the China National Knowledge Infrastructure (CNKI) database, and Wan fang database] from the inception to May 2022 for randomized controlled trials (RCTs) related to acupuncture treatment combined with cognitive rehabilitation (CR) for PSCI. Two investigators independently used a pre-designed form to extract valid data from eligible RCTs. The risk of bias was assessed through tools provided by the Cochrane Collaboration. The meta-analysis was implemented through Rev Man software (version 5.4). The strength of the evidence obtained was evaluated using GRADE profiler software. Adverse events (AEs) were collected by reading the full text and used to evaluate the safety of acupuncture treatment. Results: Thirty-eight studies involving a total of 2,971 participants were included in this meta-analysis. Overall, the RCTs included in this meta-analysis were poor in methodological quality. The combined results showed that acupuncture treatment combined with CR showed significant superiority compared to CR alone in terms of improving cognitive function [Mean Difference (MD) = 3.94, 95% confidence intervals (CI): 3.16-4.72, P < 0.00001 (MMSE); MD = 3.30, 95%CI: 2.53-4.07, P < 0.00001 (MoCA); MD = 9.53, 95%CI: 5.61-13.45, P < 0.00001 (LOTCA)]. Furthermore, the combination of acupuncture treatment and CR significantly improved patients' self-care ability compared to CR alone [MD = 8.66, 95%CI: 5.85-11.47, P < 0.00001 (MBI); MD = 5.24, 95%CI: 3.90-6.57, P < 0.00001 (FIM)]. Meanwhile, subgroup analysis showed that MMSE scores were not sufficiently improved in the comparison of electro-acupuncture combined with CR versus CR alone (MD = 4.07, 95%CI: -0.45-8.60, P = 0.08). However, we also observed that electro-acupuncture combined with CR was superior to the use of CR alone in improving MoCA and MBI scores in patients with PSCI [MD = 2.17, 95%CI: 0.65-3.70, P = 0.005 (MoCA); MD = 1.74, 95%CI: 0.13-3.35, P = 0.03 (MBI)]. There was no significant difference in the occurrence of adverse events (AE) between acupuncture treatment combined with CR and CR alone (P > 0.05). The certainty of the evidence was rated low level because of flaws in the study design and considerable heterogeneity among the included studies. Conclusion: This review found that acupuncture treatment combined with CR may have a positive effect on improving cognitive function and self-care ability in PSCI patients. However, our findings should be treated with caution owing to the existence of methodological quality issues. High-quality studies are urgently required to validate our results in the future.

[Impounding Impacts of the Three Gorges Reservoir on Phytoplankton Function Groups and Its Relationship with Resource Use Efficiency].

In order to investigate the relationship between phytoplankton community functional group compositions and resource use efficiency in important tributaries of the Three Gorges Reservoir, phytoplankton and environment parameters were sampled from five tributaries, the Xiangxi River, Daning River, Meixi River, Pengxi River, and Huangjin River, in August and November, 2020. There were 119 species (variants) belonging to 62 genera and 7 phyla identified in summer, whereas 118 species (variants) belonging to 7 divisions of 58 genera were found in winter. According to Padisak's theory, all phytoplankton were divided into 25 functional groups, of which there were six important functional groups in both summer and winter:L0, H1, D, Y, MP, and P in summer and L0, H1, A, M, MP, and Y in winter. The α-diversity of the phytoplankton functional group in summer was higher than that in winter. Moreover, a higher α-diversity was also found in downstream samples relative to that in upstream samples, indicating that the community structure was more complex, and the community stability was relatively better in downstream regions of the rivers. Redundancy analysis (RDA) showed that the environment factors, i.e., ν, pH, permanganate index, WT, and RUETN, significantly affected phytoplankton functional groups (P<0.05). Variance partitioning analysis (VPA) indicated that environmental factors had a higher explanatory degree for the change in functional group composition in summer (45.23%); on the contrary, resource use efficiency had a higher explanatory degree in winter (42.33%). The linear fitted model showed that functional groups L0, H1, D, and Y showed a significant positive correlation relationship with RUETN and RUETP in summer, whereas only four functional groups (M, MP, Y, and A) had a linear relationship with RUETP, and all function groups had a good linear relationship with RUETN in winter. These results indicated that the functional groups belonging to cyanobacteria, dinoflagellates, and cryptophyta were more efficient at using limited resources in summer, whereas the diatoms had a good linear relationship with resource use efficiency and formed a dominant group in the low temperature environment of winter. These results suggest that the impounding of the Three Gorges Reservoir area can significantly change the resource use efficiency of phytoplankton, resulting in changes in the phytoplankton functional group composition and community structure.

[Dietary micronutrient intake of children aged 2-5 years in China in 2019-2021].

OBJECTIVE: To describe dietary intake of calcium, iron, zinc, selenium, vitamin A, vitamin B_1, vitamin B_2 and vitamin C and compare the intake between urban and rural areas among preschool children aged 2-5 years based on the data from the National Nutrition and Health Systematic Survey for Children 0-17 Years of Age in China. METHODS: Children from 14 provinces were selected by multi-stage stratified random cluster sampling, and the dietary data of preschool children aged 2-5 years were recorded using the 3 day 24-hour weighted food records method. SAS 9.4 was used to calculate dietary intake of these micronutrients based on the Chinese Food Composition Table and to compare the intake between urban and rural areas. The risk of insufficient or excessive intake of micronutrients among Chinese children aged 2-5 years was assessed according to the Chinese Dietary Reference Intakes(DRIs) 2013 edition. RESULTS: A total of 820 children aged 2 to 5 years were selected. The median daily dietary calcium intake of children aged 2-5 years in China was 433.7, 338.9, 356.4 and 347.4 mg, respectively. The median daily dietary intake of vitamin B_1 of children aged 2-5 years was 0.5 mg for all age groups. The median daily dietary vitamin B_2 intake of children aged 2-5 years was 0.7, 0.6, 0.6 and 0.6 mg, respectively. The median daily dietary intake of vitamin C of children aged 2-5 years was 37.9, 37.4, 44.0 and 40.0 mg, respectively. The median daily dietary selenium intake of children aged 2-5 years was 17.1, 20.5, 22.7 and 22.3 µg, respectively. Dietary calcium intake for aged 2-5 years, dietary vitamin B_2 intake for aged 2-4 years, dietary iron, selenium, zinc and vitamin B_1 intake for aged 2-3 years was significantly greater in urban children than rural children. Among all nutrients, the proportion of dietary calcium intakes below the estimated average requirement(EAR) was the highest in aged 2-5 years(61.4%, 76.4%, 91.4% and 91.5%, respectively). The proportions of dietary vitamin B_1, vitamin C and selenium intake lower than EAR of children aged 2-5 years in China were 52.4%-63.2%, 42.8%-50.2% and 46.6%-58.7%, respectively. COUCLUSION: The dietary calcium intake of children aged 2-5 years in China remains insufficient for these children, especially for rural children. Dietary vitamin B_1, vitamin C and selenium intake should be improved.
