Effectiveness of the "Hand as Foot" teaching method in human physiology: A randomized controlled trial.

BACKGROUND: The "Hand as Foot" teaching method, an innovative approach in medical education, utilizes hand gestures to simulate anatomical structures and functions. This study aimed to assess the effectiveness of the "Hand as Foot" teaching method compared to traditional method in the "Human Physiology" course. METHODS: During the 2023 spring semester, a randomized controlled trial involved 84 health management students. Participants were randomly assigned to the "Hand as Foot" teaching group or the traditional teaching group. A self-designed Likert scale was used to evaluate students' perceptions of teaching effectiveness, covering dimensions such as engagingness, intuitiveness, facilitation of understanding, enhancement of memorization, and effortlessness of learning. Additionally, a knowledge assessment test was administered to measure knowledge acquisition. RESULTS: The "Hand as Foot teaching method" group (41 students) reported significantly higher ratings for all dimensions of teaching effectiveness compared to the traditional teaching group (43 students) (p ≤ 0.01). Despite the lack of statistical significance, the experimental group's test scores were notably superior (Mean = 6.35 vs. Mean = 5.94). DISCUSSION: The "Hand as Foot" teaching method demonstrated superior effectiveness in engaging students, facilitating comprehension, and enhancing memorization. Its interactive and tangible nature provided a holistic learning experience, enabling students to visualize complex physiological mechanisms. Additionally, it fostered active student participation and a desire for deeper understanding. CONCLUSION: While the "Hand as Foot" teaching method demonstrated strengths in engaging students and aiding comprehension, further researches with larger and diverse cohorts are needed to gauge its impact on learning outcomes and broader applicability.

Effects of Yulin Tong Bu formula on modulating gut microbiota and fecal metabolite interactions in mice with polycystic ovary syndrome.

Background: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism, ovarian dysfunction and polycystic ovarian morphology. Gut microbiota dysbiosis and metabolite are associated with PCOS clinical parameters. Yulin Tong Bu formula (YLTB), a traditional Chinese medicine formula, has been recently indicated to be capable of ameliorating polycystic ovary symptoms and correcting abnormal glucose metabolism. However, the therapeutic mechanism of YLTB on PCOS has not been fully elucidated. Methods: A pseudo sterile mouse model was established during this four-day acclimatization phase by giving the animals an antibiotic cocktail to remove the gut microbiota. Here, the therapeutic effects of YLTB on PCOS were investigated using dehydroepiandrosterone plus high-fat diet-induced PCOS mice model. Female prepuberal mice were randomly divided into three groups; namely, the control group, PCOS group and YLTB (38.68 g·kg-1·day-1) group. To test whether this effect is associated with the gut microbiota, we performed 16S rRNA sequencing studies to analyze the fecal microbiota of mice. The relationships among metabolites, gut microbiota, and PCOS phenotypes were further explored by using Spearman correlation analysis. Then, the effect of metabolite ferulic acid was then validated in PCOS mice. Results: Our results showed that YLTB treatment ameliorated PCOS features (ovarian dysfunction, delayed glucose clearance, decreased insulin sensitivity, deregulation of glucolipid metabolism and hormones, etc.) and significantly attenuated PCOS gut microbiota dysbiosis. Spearman correlation analysis showed that metabolites such as ferulic acid and folic acid are negatively correlated with PCOS clinical parameters. The effect of ferulic acid was similar to that of YLTB. In addition, the bacterial species such as Bacteroides dorei and Bacteroides fragilis were found to be positively related to PCOS clinical parameters, using the association study analysis. Conclusion: These results suggest that YLTB treatment systematically regulates the interaction between the gut microbiota and the associated metabolites to ameliorate PCOS, providing a solid theoretical basis for further validation of YLTB effect on human PCOS trials.

Effects of anthocyanin-rich supplementation on cognition of the cognitively healthy middle-aged and older adults: a systematic review and meta-analysis of randomized controlled trials.

CONTEXT: The prevalence of age-related cognitive decline has been on the rise as the global population age, putting the independence and quality of life of elderly at risk. Anthocyanin, as a subclass of dietary flavonoids, may have a beneficial impact on cognitive outcomes. OBJECTIVES: To examine the effects of dietary anthocyanin supplementation on cognition of the cognitively healthy middle-aged and older adults. DATA SOURCES: PubMed, ScienceDirect, CINAHL, EMBASE, ProQuest and Cochrane databases were searched. DATA EXTRACTION AND ANALYSIS: Thirteen studies were included in this meta-analysis. Anthocyanin-rich supplementation was found to significantly improve the processing speed of the older adults (95%CI 0.08, 0.44; P = 0.004). No significant differences were observed between intervention and control groups on memory, attention, executive function and psychomotor performance. Current neuroimaging studies have found promising effects of anthocyanin supplementation on brain activation and cerebral perfusion. CONCLUSION: Anthocyanin-rich supplementation may preserve cognitive processing speed and neuro-activities in older adults, which improves their daily functioning and quality of life. This review provides useful insights to guide direction and methodological designs for future studies to explore the underlying mechanisms of anthocyanins.

Curcumin nanoparticles combined with 3D printed bionic tumor models for breast cancer treatment.

Compared with conventional therapeutic approaches, nanomedicines are attracting a growing interest due to their better targeting ability, higher delivery efficiency, and good water solubility. However, conventional drug efficacy assessment methods are based on a two-dimensional (2D) culture approach of single cells to obtainin vitrotherapeutic effects, which may not be representative of actual tumors. Based on the above considerations, the three-dimensional (3D) cell culture models became a better choice since they can increase the complexity ofin vitrosystems and provide a biomimetic microenvironment that is closer to thein vivonative than 2D cultures. In our study, curcumin nanoparticle (CurNPs) with good water solubility and good tumor therapeutic effects were prepared by combining polymeric non-ionic surfactant (Pluronic F127) with curcumin. The hybrid scaffolds based on nano-clay, sodium alginate, and gelatin were also prepared, which showed good printability and excellent biocompatibility. We then studied the therapeutic effects of CurNPs on metastatic breast cancer using a 3D tumor model fabricated with scaffold-bound metastatic breast cancer (MDA-MB-231) cells. It was showed that the 3D cell model presented better cell proliferation effect while compared with 2D version. Additionally, there was good enhanced permeability and retention effect when CurNPs entered with better accumulate in 3D cell 'tumor' sites which represented more realistic response of a more real tumor treatment effect for breast cancer cells. Our study indicated that the combinational of nanomaterials with 3D cell 'tumor' models provided an alternative and better platform for drug screening and has great potential be used as safe and effective treatment screening for breast cancer.

Long-term survival analysis of patients with stage IIIB-IV non-small cell lung cancer complicated by type 2 diabetes mellitus: A retrospective propensity score matching analysis.

BACKGROUND: This study aimed to determine the effect of type 2 diabetes mellitus (T2DM) on overall survival (OS) of patients with stage IIIB-IV non-small cell lung cancer (NSCLC). METHODS: We retrospectively analyzed patients with stage IIIB-IV NSCLC from January 2015 to December 2018 in the Department of Oncology at the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine. Kaplan-Meier plots, log-rank tests, and Cox proportional hazards regression models were used to describe the effect of T2DM on the OS of patients with stage IIIB-IV NSCLC. RESULTS: This study collected data on 76 patients with NSCLC and T2DM (group A) and 214 NSCLC patients without T2DM (group B). After propensity score matching (PSM) analysis, 74 patients were included in each group. The mean OS of all patients was 17 months (range, 11-31 months). The mean OS of group A was 15 months (range, 8-25 months) and the mean OS of group B was 20 months (range, 14-39 months). The mean OS of group B was longer than group A, and the difference was statistically significant. Univariate analysis of the clinical data showed that T2DM and complications were significantly correlated with the prognosis of patients with stage IIIB-IV NSCLC (p = 0.003 and p = 0.034). Multivariate Cox model analysis showed that T2DM and complications were independent prognostic factors for patients with stage IIIB-IV NSCLC (p = 0.002 and p = 0.024, respectively). CONCLUSION: Stage IIIB-IV NSCLC patients without T2DM have an increased OS compared to patients with stage IIIB-IV NSCLE and T2DM.

[Identification of GeERF transcription factors in Gelsmium elegans and their expression under low temperature stress].

With prominent medicinal value, Gelsemium elegans has been overexploited, resulting in the reduction of the wild resource. As a result, artificial cultivation turns out to be a solution. However, this medicinal species is intolerant to low temperature, and thus genes responding to the low temperature are important for the cultivation of this species. Based on the transcriptome database of G. elegans at 4 ℃, 29 differentially expressed GeERF genes were identified. Bioinformatics analysis of 21 GeERF gene sequences with intact open reading frames showed that 12 and 9 of the GeERF proteins respectively clustered in DREB subgroup and ERF subgroup. GeDREB1 A-1-GeERF6 B-1, with molecular weight of 23.78-50.96 kDa and length of 212-459 aa, were all predicted to be hydrophilic and in nucleus. Furthermore, the full-length cDNA sequence of GeERF2B-1 was cloned from the leaves of G. elegans. Subcellular localization suggested that GeERF2B-1 was located in the nucleus. According to the quantitative reverse-transcription PCR(qRT-PCR), GeERF2B-1 showed constitutive expression in roots, stems, and leaves of G. elegans, and the expression was the highest in roots. In terms of the response to 4 ℃ treatment, the expression of GeERF2B-1 was significantly higher than that in the control and peaked at 12 h, suggesting a positive response to low temperature. This study lays a scientific basis for the functional study of GeERF transcription factors and provides gene resources for the improvement of stress resistance of G. elegans.

Identification of Forsythia suspensa (Thunb.) Vahl in different harvest periods using intelligent sensory technologies, HPLC characteristic fingerprint coupled with chemometrics.

INTRODUCTION: Forsythia suspensa (Thunb.) Vahl (FS), the fruit of Oleaceae plants, as a large part of traditional Chinese medicine, is classified as "Qingqiao (Q)" and "Laoqiao (L)" based on the harvest time. Because the maturation of FS is a gradual process, its accurate identification based on different maturity levels is an important issue. OBJECTIVES: We suggest colorimetric, electronic tongue, and high-performance liquid chromatography (HPLC) characteristic fingerprints to discriminate FS in different harvest periods. MATERIAL AND METHODS: First, FS fruits from different harvest times were collected, and then, their colour parameters, E-tongue sensory properties, HPLC characteristic fingerprints, and contents of nominal ingredients were determined. Finally, multivariate statistical analyses, including three-dimensional scatter plots, hierarchical cluster, principal component, linear discriminant, similarity, and partial least squares discriminant analyses were performed. RESULTS: The results demonstrated that the three experimental techniques could effectively discriminate FS based on different harvest times with 100% accuracy. Under the qualitative conditions, nine common peaks were identified in the HPLC fingerprints of 60 samples, among which, six peaks [variable importance in projection (VIP) > 1] could be used as index peaks for qualitative identification. In fact, the contents of quality marker components, including forsythin, phillygenin, rutin and forsythoside A, were significant different (P < 0.001) at different harvest times. Interestingly, the quality markers not only accurately reflected the maturity of FS but also showed close correlations with the colour parameters and sensory E-tongue responses. CONCLUSION: In our present investigation, bionic technologies, including a colorimeter, E-tongue analysis, and HPLC characteristic fingerprints, combined with chemometrics, were employed to develop a novel and accurate method for discriminating FS based on different harvest times.

Objective: To investigate the intervention effects of curcumin (Curc) on liver injury induced by chronic alcohol addiction in mice. Methods: Thirty Balb/c mice were randomly divided into normal control group (Control), model group (Model), low-dose Curc group (5 mg/kg, Curc-L), medium dose Curc group (10 mg/kg, Curc-M) and high-dose Curc group (15 mg/kg, Curc-H), with 6 mice in each group. The chronic alcohol addiction liver injury model was prepared with 20% liquor. The mice in control group were given 2 ml of normal saline every day. The mice in model group were given 5 ml/kg of 20% liquor every day, and the mice in Curc treatment group were treated with Curc at the doses of 5, 10, 15 mg/kg in 2 ml saline every day for 35 days. The weight of liver was measured and the health status of mice was observed. Serum ALT, AST, ALP and liver TG, TC, HDL-C, LDL-C, MDA, SOD, GSH-Px and NO were measured. The pathological changes of liver tissues stained with hematoxylin and eosin were observed. Results: Compared with the control group, the liver mass and serum levels of ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, LDL-C in the model group were increased significantly (P＜0.05, P＜0.01), the activities of SOD and GSH-Px were decreased significantly (P＜0.05, P＜0.01), the liver cells were vacuolated and infiltrated with inflammatory cells, and the expression levels of NF-κB and MAPK protein in liver tissues were increased significantly (P＜0.01). Compared with the model group, the levels of ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, LDL-C in Curc group were decreased significantly nd the activities of SOD and GSH-Px were increased significantly (P＜0.05, P＜0.01). Conclusion: Curc can effectively reduce liver tissue damage by regulating NF-κB/MAPK signal pathway.

Identification, potency evaluation, and mechanism clarification of α-glucosidase inhibitors from tender leaves of Lithocarpus polystachyus Rehd.

Lithocarpus polystachyus Rehd. known as Sweet Tea in China has attracted lots of interest for its good hypoglycemic effect and the potential as a hypoglycemic agent. Based on affinity separation-UPLC-Q-TOF-MS/MS, 54 potential α-glucosidase inhibitiors were identified and 44 were structurally determined. Out of them, 41 were identified for the first time from this plant including flavonoids, fatty acids, triterpenes, alkaloids, and coumarins. Enzyme assays revealed that flavonoids exhibited higher inhibitory activity against α-glucosidase than others with astilbin (IC50 = 6.14 µg·mL-1), morin (IC50 = 8.46 µg·mL-1), and naringenin (IC50 = 10.03 µg·mL-1) showing 2- to 4-fold higher potency than the positive control acarbose. They were proved as reversible inhibitors with mixed inhibition mechanism. Ki (Ki') values and molecular dockings strongly supported the potency order of astilbin, morin and naringenin that showed in the enzyme assays.

Taurochenodeoxycholic acid inhibits the proliferation and invasion of gastric cancer and induces its apoptosis.

Taurochenodeoxycholic acid (TCDCA) is the principal ingredient of Compound Shougong Powder. Despite traditional Chinese medicine (TCM) research demonstrates that Compound Shougong Powder can restrict tumor growth, whether TCDCA exerts a role in suppressing cancer as the major ingredient of Compound Shougong Powder remains unknown. This study aims to clarify the regulatory mechanism of TCDCA on gastric cancer. Gastric cancer cells SGC-7901 were cultured to investigate the effects of TCDCA on proliferation and apoptosis. Furthermore, a subcutaneously implanted tumor model was established using SGC-7901 cells in BALB/C nude mice and tumor volume was measured under low and high dose treatment of TCDCA. Cell proliferation, apoptosis, and invasion were subjected to 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay, flow cytometry, and transwell assay. Differentially expressed genes were screened by transcriptome sequencing. Nude mouse tumorigenicity assay was initiated to identify the effect of TCDCA on both tumor volume and weight, and the expression of candidate genes screened by transcriptome sequencing was determined by real-time fluorescence quantification (qPCR) and Western blot. The experiments revealed that TCDCA could significantly inhibit the proliferation and invasion of gastric cancer cells and induce apoptosis of these cells. Meanwhile, test findings via in vivo indicated that TCDCA severely diminished the volume and weight of tumors. This study first demonstrated that TCDCA inhibited the proliferation and invasion of gastric cancer and induced apoptosis, which is expected to serve as an experimental basis for the application of TCM in tumor therapeutic options. PRACTICAL APPLICATIONS: Through this study, the inhibitory effect of Taurochenodeoxycholic acid on gastric cancer can be clarified, which provides a new research basis for the application of traditional Chinese medicine (TCM) and TCM monomer in cancer. In addition, this study can further promote the research and application of Chinese traditional medicine, which has important application value and economic benefits.

Nine prenylated acylphloroglucinols with potential anti-depressive and hepatoprotective activities from Hypericum scabrum.

In our screening program for new biologically active secondary metabolites, nine new polycyclic polyprenyled acylphloroglucinols, hyperscabins D-L, together with three known compounds, were obtained from the aerial parts of Hypericum scabrum. The chemical structures of 1-9 were characterized by extensive spectroscopic analyses, nuclear magnetic resonance calculation with DP4+ probability analysis, and the electronic circular dichroism spectra were calculated. Compound 1 was an unusual prenylated acylphloroglucinol decorated with a 5-oxaspiro [4,5] deca-1,9-dione skeleton. Compound 2 was a newly identified spirocyclic polyprenylated acylphloroglucinol possessing a rare 5,5-spiroketal segment. Compounds 3, 8, and 10 (10 µM) exhibited pronounced hepatoprotective activity against d-galactosamine-induced WB-F344 cell damage in vitro assays. All test compounds (1, 3, and 7-12) demonstrated potential inhibitory effects at 10 µM against noradrenalinet ([3H]-NE) reuptake in rat brain synaptosome.

Ameliorative effects of Qingganjiuwei powder, a traditional Mongolian medicine, against CCl4-induced liver fibrosis in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Qingganjiuwei powder (QGJWS) is a well-known traditional drug containing nine kinds of medicinal materials. This drug is commonly used in the Inner Mongolia region and exerts remarkable clinical effects on hepatic protection. AIM OF THE STUDY: To investigate whether QGJWS inhibits liver fibrosis in rats and to reveal its potential mechanisms. METHODS: Liver fibrosis model was induced by CCl4 for 8 weeks in SD rats. Next, rats were intragastrically administered quantum satis doses of QGJWS (0.525, 1.575, 4.725 g/kg per day) or Silymarin (SIL; 120 mg/kg per day) for 8 weeks. Afterwards, the rats were sacrificed, and serum aminotransferase (ALT and AST) levels, histopathological changes as well as the mRNA and protein expression of matrix metalloproteinase 2 (MMP2), MMP9, tissue inhibitor of metalloproteinase1 (TIMP1), collagen type Ⅰ(COL1), α-smooth muscle actin (α-SMA), combined with phosphorylation levels of extracellular signal-regulated kinase (ERK), C-Jun amino-terminal kinases (JNKs) and stress-activated protein kinase-2 (p38) protein in liver tissues were measured in each groups, respectively. RESULTS: The symptoms and signs of the model rats were consistent with the diagnostic criteria of liver fibrosis. By contrast, treatment with QGJWS clearly improved the general condition of rats. Also, the morphology and structure of liver can be ameliorated, there are fewer hepatocyte necrosis and lymphocytic infiltration and pseudolobuli in QGJWS treatment groups as demonstrated by histopathological analysis, thus helping bring about lower METAVIR scores. QGJWS administration also dramatically decreased serum ALT and AST levels. Further immunohistochemistry, western blotting and Real-Time PCR analysis revealed that QGJWS significantly enhanced the mRNA and protein expression of MMP2, MMP9, and downregulated the expression levels of COL1, TIMP1 and α-SMA. Furthermore, QGJWS reduced the activities of mitogen-activated protein kinases (MAPKs) pathway in liver by inhibited the phosphorylation of ERK, JNKs and p38 proteins. CONCLUSIONS: QGJWS offers notable protection against CCl4-induced liver fibrosis in rats, which may be due to its ability to inhibited the MAPKs signaling pathway.

Acteoside-improved streptozotocin-induced learning and memory impairment by upregulating hippocampal insulin, glucose transport, and energy metabolism.

Alzheimer's disease (AD), a neurodegenerative disease, has been, by and large, correlated to insulin pathway, glucose level, and energy metabolism in the brain. Intracerebroventricular administration of streptozotocin (ICV-STZ) leads to glucose and energy metabolism dysfunction, cognitive impairment, and increased oxidative stress in the brain. Acteoside has a myriad of pharmacological effects on the brain, namely, neuroprotection and recuperation of cognitive functions. The primary focus of the current study was to examine the effect of acteoside on insulin, glucose transport, and energy metabolism in the hippocampal area of the brain. The behavioral experiments such as spatial memory, active learning, and passive memory suggested that acetoside ameliorated the ICV-STZ-induced learning and cognitive impairment. The acteoside induced increase in the protein expression of glucose transporters (Glu T1, Glu T3, and Glu T4), glucose, and insulin levels in the hippocampus for maintaining normal learning and memory function were demonstrated by Western blot. In addition, acteoside's long-term oral administration increased the the ratio of ATP content divided by ADP content (ATP/ADP) ratio, which, in turn, reduced the reactiveoxygen species (ROS) level and improved the cellular oxidative stress response. Compared with the model group, the above results show significant differences in different degrees (p < .05 or p < .01). This study suggests that acteoside can ameliorate the ICV-STZ-induced learning and memory impairment caused due to insulin receptor, insulin receptor substrate 1, Glu T1, Glu T3, and Glu T4 pathways by triggering intracerebral metabolism.

Investigation on Compatibility Characteristics and Mechanism of Baimai Ointment in Intervening "White Vein" by Integrating Bioinformatics Analysis and Prescription Rule Discovery / 中国实验方剂学杂志

Objective:To explore the mechanism and compatibility characteristics of Baimai ointment （BMO） in the treatment of white vein disease from the network perspective based on system theory， so as to provide biological basis for its clinical application. Method:The chemical components and the corresponding candidate target spectra of BMO were obtained from The Encyclopedia of Traditional Chinese Medicine （ETCM） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. According to the clinicopathological characteristics of white vein disease， focusing on four diseases/symptoms including neuropathic pain， inflammatory pain， chronic pain and lumbar disc herniation root neuralgia， the gene sets related to white vein disease were collected in Human Phenotype Ontology （HPO）， DisGeNET and other databases， then the interaction network of the targets of active components in BMO-gene sets related to white vein disease was constructed. On this basis， the hub network nodes were selected and enriched for exploring the mechanism of four functional groups of BMO in the treatment of white vein disease such as Huoxue Tongluo group （Curcumae Longae Rhizoma， Moschus， Tronae）， Xingqi Zhitong group （Myristicae Semen， Nardostachyos Radix et Rhizoma， Acori Calami Rhizoma）， Wenjing Sanhan Tongluo group （Zingiberis Rhizoma， Zanthoxyli Pericarpium， Caraway） and Jianpi Wenshen Qianggu group （Actinolite， Glycyrrhizae Radix et Rhizoma）. Result:The enriched pathways of the four functional groups in BMO were mainly distributed in three modules of nervous system function， inflammation-immune system regulation and body energy metabolism， and each module was connected by common target genes especially had its own focus. Among them， the regulation of nervous system function in Huoxue Tongluo group and Xingqi Zhitong group could be summarized as Huoxue Buqi and Xingshen Kaiqiao. Xingqi Zhitong group and Jianpi Wenshen Qianggu group were mainly used to promote the operation of Qi， promote blood metaplasia， enhance immunity and maintain the regulation of inflammation-immune system. Jianpi Wenshen Qianggu group and Wenjing Sanhan Tongluo group mainly regulated body energy metabolism by invigorating the spleen and supplementing Qi as well as warm-heat medicine. The whole formula focused on the multi-dimensional and multi-level mechanism of BMO in the intervention of white vein disease. Each functional group emphasized its respective characteristics in nervous system function， inflammation-immune regulation， and body energy metabolism. Two types of networks analysis models complemented and verified each other. Conclusion:BMO plays a role in the treatment of white vein disease mainly by regulating the function of nervous system， maintaining the balance of inflammation-immune system and interfering with energy metabolism. The relevant research results can provide reference for the in-depth exploration of the mechanism of BMO， and help to guide the clinical rational use of this preparation.

Systems Pharmacology Dissection of Mechanisms of Dengzhan Xixin Injection against Cardiovascular Diseases.

Dengzhan Xixin injection (DZXXI), a herbal product prepared from a Chinese herb called Erigeron breviscapus, is a classical and traditional therapeutic for cadiovascular diseases (CVDs), including coronary heart disease (CHD), angina, and stroke, etc. However, its potential pharmacology mechanism against CVDs remains unclear. In this paper, a systems pharmacology-based strategy is presented for predicting drug targets and understanding therapeutic mechanisms of DZXXI against CVDs. The main ingredients were identified by HPLC-diode array detector (DAD). The target fishing was performed on the PharmMapper Server (http://lilab-ecust.cn/pharmmapper/). Potential targets were confirmed by two molecular docking tools, Sybyl-X 1.3 and Ledock to ensure the accuracy. The resulting target proteins were applied as baits to fish their related diseases and pathways from the molecular annotation system (MAS 3.0, http://bioinfo.capitalbio.com/mas3/) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database (http://www.genome.jp/kegg/). Network generation and topological analysis were performed in Cytoscape 3.6.0. 15 main ingredients from DZXXI were identified. Forty five putative drug targets and 50 KEGG pathways, which have highly relevance to the therapeutic effects of DZXXI against CVDs, were then obtained. The systems analysis suggested that DZXXI could attenuate cardiac fibrosis, regulate cardiac contractility, and preserve heart function in adverse cardiac remodeling; meanwhile DZXXI also could have the function of activating blood circulation and dilating blood vessels. DZXXI exerts its therapeutic effects on CVDs possibly through multi-targets including CMA1, epidermal growth factor receptor (EGFR), phenylalanine-4-hydroxylase (PAH), SRC, F7, etc., and multi-pathways including Focal adhesion, mitogen-activated protein kinase (MAPK) signaling pathway, complement and coagulation cascades, Wnt signaling pathway, vascular endothelial growth factor (VEGF) signaling pathway, Renin-angiotensin system, etc.

Effects of mindfulness-based cognitive therapy on breast cancer survivors with insomnia: A randomised controlled trial.

OBJECTIVE: We investigated the effects of mindfulness-based cognitive therapy on insomnia (MBCT-I) in breast cancer survivors. METHODS: In total, 136 participants were allocated randomly to a MBCT-I group or a waitlist control (WLC) group. Indicators of insomnia and mindfulness were evaluated using the Insomnia Severity Index, actigraphy and the Five Facet Mindfulness Questionnaire. Data were collected at baseline (T1), post-intervention (T2), 3-month follow-up (T3) and 6-month follow-up (T4) time points. RESULTS: Insomnia severity decreased significantly in the MBCT-I group, compared with the WLC group, at T2, T3 and T4 (all p < .001). We found that 59.6% of the MBCT-I group with moderate and severe insomnia improved to no insomnia and subclinical insomnia at T4 relative to T1, accounting for 7.9% and 55.3%, respectively. Compared with the WLC group, the MBCT-I group improved on actigraphy measures of sleep; they exhibited a pattern of decreased sleep onset latency and waking after sleep onset, as well as increased total sleep time and sleep efficiency. Mindfulness also increased more in the MBCT-I group than in the WLC group at T2, T3 and T4 (all p < .001). CONCLUSIONS: MBCT-I may be an efficacious non-pharmacologic intervention to improve sleep quality in breast cancer survivors.

Non-Pharmacological Interventions for Post-Stroke Fatigue: Systematic Review and Network Meta-Analysis.

Post-stroke fatigue (PSF) is one of the most serious sequelae, which often interferes with the rehabilitation process and impairs the functional recovery of patients. Due to insufficient evidence, it is unclear which specific pharmacological interventions should be recommended. Therefore, in this paper, we compare the effectiveness of non-pharmacological interventions in PSF. A systematic review and network meta-analysis of randomized controlled trials were performed using EMBASE, MEDLINE, CINAHL, Cochrane library, ClinicalTrials.gov, CNKI, and CQVIP, from inception to January 2018, in the English and Chinese languages. RCTs involving different non-pharmacological interventions for PSF with an outcome of fatigue measured using the Fatigue Severity Scale were included. Multiple intervention comparisons based on a Bayesian network are used to compare the relative effects of all included interventions. Ten RCTs with eight PSF non-pharmacological interventions were identified, comprising 777 participants. For effectiveness, most interventions did not significantly differ from one another. The cumulative probabilities of the best non-pharmacological intervention for fatigue reduction included Community Health Management (CHM), followed by Traditional Chinese Medicine (TCM) and Cognitive Behavioral Therapy (CBT). Network meta-analysis based on data from the selected RCTs indicated that the eight PSF non-pharmacological interventions shared equivalent efficacy, but CHM, TCM, and CBT showed potentially better efficacy. In the future, fatigue needs to be recognized and more accurate assessment methods for PSF are required for diagnosis and to develop more effective clinical interventions.

Effects of low-frequency ultrasonic pre-treatment in water/oil medium simulated system on the improved processing efficiency and quality of microwave-assisted vacuum fried potato chips.

The effects of low-frequency ultrasonic pre-treatment in water/oil medium simulated system on the improved processing efficiency and quality of microwave-assisted vacuum fried potato chips were investigated. The water medium system (distilled water and 5% NaCl osmotic solution) and oil medium system (90 °C) were designed with different power levels of ultrasound to simulate the ultrasonic conditions. Results showed that the changes of moisture content, water loss, solid gain and dielectric properties of potato slices were facilitated by the ultrasonic treatment. LF-NMR analysis showed the binding force between the moisture and structure in the material was significantly (p < 0.05) weakened. The changes become greater with the increase of ultrasonic power levels. Microscopic channels and disruptions were induced on the microstructure by the ultrasonic treatment. The effective moisture diffusivity of vacuum fried (VF) potato chips was increased by about 56.2%-67.0% and 53.9% with the combination of microwave energy and the ultrasonic pre-treatment in water and oil medium simulated system, respectively. The oil uptake, hardness, shrinkage, total color change and water activity of vacuum fried samples were significantly (p < 0.05) decreased by the assist of microwave energy combined ultrasonic pre-treatment.

Simultaneous Determination of Five Phenolic Acids and Four Flavonoid Glycosides in Rat Plasma Using HPLC-MS/MS and Its Application to a Pharmacokinetic Study after a Single Intravenous Administration of Kudiezi Injection.

This study has developed a reliable and precise high performance liquid chromatography-tandem mass spectrometry method for the simultaneous determination of five phenolic acids and four flavonoid glycosides in rat plasma after a single intravenous administration of Kudiezi injection (KI). Chromatographic separation was carried out on an Ultimate®XB-C18 column (4.6 × 100 mm, 3.5 µm) using a gradient elution program with a mobile phase consisting of water containing 0.5% acetic acid and acetonitrile at a flow rate of 0.6 mL/min. Detection was performed on a triple-quadrupole tandem mass spectrometry using multiple reaction monitoring in negative electrospray ionization mode. The calibration curves of all analytes showed good linearity (R² > 0.990). The results of selectivity, intra-day and inter-day precisions, extraction recoveries, matrix effects and stability were satisfactory. Pharmacokinetic parameters showed that luteolin-7-O-ß-d-gentiobioside, luteolin-7-O-ß-d-glucuronide, luteolin-7-O-ß-d-glucoside and apigenin-7-O-ß-d-glucuronide were eliminated quickly (0.07 h < t1/2 < 0.66 h), whereas 5-caffeoylquinic acid, caftaric acid, chlorogenic acid, 4-caffeoylquinic acid and caffeic acid were eliminated relatively slowly (2.22 h < t1/2 < 6.09 h) in rat blood. The pharmacokinetic results would be valuable to identify bioactive constituents, elucidate mechanisms of pharmacological actions or adverse drug reactions and guide the rational clinical use of KI.

In recent years, interest in natural plant extracts for cancer treatment is growing in the drug development field. Ginkgo biloba exocarp extract (GBEE) is known for possessing inhibitory effects on various mouse and human cancer cells. And no adverse reactions were observed during its clinical application to cancer patients. The aim of this study is to investigate the inhibitory effect of GBEE on the metastasis of B16-F10 melanoma and its related mechanisms. The B16-F10 melanoma lung metastasis model was established in C57BL/6J mice. It was found that GBEE inhibited the growth and pulmonary metastasis of B16-F10 melanoma transplanted tumor and downregulated the level of MMP-9 protein. Meanwhile, the B16-F10 cells were used to study in vitro. The results showed that GBEE inhibited the proliferation and migration of B16-F10 cells. Simultaneously, it suppressed the heterogeneous adhesion of B16-F10 cells to human umbilical vein endothelial cells (HUVEC) in a concentration-dependent manner. In addition, the levels of p-PI3K, p-Akt, NF-κB, and MMP-9 were decreased, while the PI3K and Akt were not significantly changed. These results indicate that GBEE can inhibit the metastasis of B16-F10 melanoma via multiple links and the molecular mechanism involved the regulation of PI3K/Akt/NF-κB/MMP-9 signaling pathway.
