Exploring the Diagnostic and Prognostic Significance of Alkaline Phosphatase on Neutrophil Surface Membrane in Patients with Sepsis.

Background: Sepsis, characterized by life-threatening organ dysfunction, stems from an unregulated host response. Timely identification is pivotal for enhancing the prognosis of sepsis patients. Objective: This study aims to explore the diagnostic and prognostic values of alkaline phosphatase on the surface membrane of neutrophils (mNAP) in peripheral blood among sepsis patients. Design: The study employed a retrospective design. Setting: This study was conducted at Donghai County People's Hospital. Participants: A total of 180 sepsis patients were selected and categorized into the sepsis shock group (n=45) and the sepsis non-shock group (n=135). Additionally, 35 patients with non-infectious systemic inflammatory response syndrome served as the control group. Interventions: mNAP was assessed via flow cytometry, while serum procalcitonin (PCT) and C-reactive protein (CRP) levels were measured through immunoassay. Primary Outcome Measures: (1) Changes in mNAP, PCT, and CRP. (2) Correlation of mNAP with CRP and PCT in sepsis patients. (3) Diagnostic values of mNAP, PCT, and CRP in sepsis. Results: Statistically significant differences in mNAP, PCT, and CRP were observed between the sepsis shock group, the sepsis non-shock group, and the control group (P = .000). The median value of mNAP (22627 Ab/c) in the 28-day death group was significantly higher than that (5100 Ab/c) in the survival group (P = .000). Spearman rank correlation analysis indicated a positive correlation between mNAP, PCT, and CRP in sepsis patients (P < .01). Conclusions: Both mNAP and PCT exhibit superior diagnostic specificity and sensitivity compared to CRP. While mNAP demonstrates similar sensitivity to PCT in diagnosing sepsis, its diagnostic specificity surpasses that of PCT. mNAP holds promise as a novel marker for the diagnosis and prognosis of sepsis.

Combination Therapy with a TLR7 Agonist and a BRD4 Inhibitor Suppresses Tumor Growth via Enhanced Immunomodulation.

JQ-1 is a typical BRD4 inhibitor with the ability to directly fight tumor cells and evoke antitumor immunity via reducing the expression of PD-L1. However, problems arise with the development of JQ-1 in clinical trials, such as marked lymphoid and hematopoietic toxicity, leading to the investigation of combination therapy. SZU-101 is a TLR7 agonist designed and synthesized by our group with potent immunostimulatory activity. Therefore, we hypothesized that combination therapy of SZU-101 and JQ-1 would target innate immunity and adaptive immunity simultaneously, to achieve a better antitumor efficacy than monotherapy. In this study, the repressive effects of the combination administration on tumor growth and metastasis were demonstrated in both murine breast cancer and melanoma models. In 4T1 tumor-bearing mice, i.t. treatment with SZU-101 in combination with i.p. treatment with JQ-1 suppressed the growth of tumors at both injected and uninjected sites. Combination therapy increased M1/M2 ratio in TAMs, decreased PD-L1 expression and promoted the recruitment of activated CD8+ T cells in the TME. In summary, the improved therapeutic efficacy of the novel combination therapy appears to be feasible for the treatment of a diversity of cancers.

Cancer chemoprevention with PV-1, a novel Prunella vulgaris-containing herbal mixture that remodels the tumor immune microenvironment in mice.

The herb Prunella vulgaris has shown significant immune-stimulatory and anti-inflammatory effects in mouse models. Here, the effects of a novel Prunella vulgaris-containing herbal mixture, PV-1, were examined in several mouse models for cancer, including chemically induced models of lung and oral cancers as well as syngraft models for lung cancer and melanoma. PV-1, consisting of extracts from Prunella vulgaris, Polygonum bistorta, Sonchus brachyotus and Dictamnus dasycarpus, exhibited no toxicity in a dose escalation study in A/J mice. PV-1 significantly inhibited mouse lung tumor development induced by the lung carcinogens vinyl carbamate and benzo[a]pyrene. PV-1 also hindered the induction of oral squamous cell carcinomas in C57BL/6 mice caused by 4-nitroquinoline-1-oxide. Flow cytometry analysis showed that PV-1 increased the numbers of CD8+ tumor-infiltrating lymphocytes (TILs) and increased the production of granzyme B, TNF-α, and IFN-γ by CD8+ TILs. PV-1 also suppressed granulocytic myeloid-derived suppressor cell numbers (g-MDSCs) and improved the anti-cancer activity of anti-PD-1 immunotherapy. These results indicate that PV-1 remodels the tumor immune microenvironment by selectively inhibiting g-MDSCs and increasing CD8+ TILs within tumors, resulting in decreased immune suppression and enhanced cancer chemopreventive efficacy.

The Chemoprevention Effects of Two Herbal Mixtures on Chemically Induced Lung Tumorigenesis in Mice.

Ruan Hua Tang (RHT) and Ruan Hua Fang (RHF) are two Chinese herbal mixtures that have been used in clinical cancer treatment for decades. This study validated our hypothesis that RHT and RHF can inhibit lung tumor development in the mouse model of Benzo(a)pyrene-induced lung tumorigenesis. An RHT oral solution was diluted to 9% and 18% in water. RHF was mixed into the diet at 15% and 30% of total food in the final doses. Two weeks after injecting BP into mice, we administered RHT and RHF for eighteen weeks. We found that 9% and 18% RHT reduced tumor multiplicity by 36.05% and 38.81% (both p < 0.05) and the tumor load by 27.13% and 55.94% (p < 0.05); 15% and 30% RHF inhibited tumor multiplicity by 12.75% and 39.84% (p < 0.01) and the tumor load by 18.38% and 61.68% (p < 0.05). Ki67 expressions in the 9% and 18% RHT groups were 19.55% and 11.51%, significantly lower than in the control (33.64%). The Ki67 levels in the 15% and 30% RHF groups were 15.56% and 14.04%, significantly lower than in the control (27.86%). Caspase 3 expressions in the 9% and 18% RHT groups were 5.24% and 7.32%, significantly higher than in the control (2.39%). Caspase 3 levels in the 15% and 30% RHF groups were 6.53% and 4.74%, significantly higher than in the control (2.07%). The bio-absorption was confirmed via a pharmacokinetic test. This study showed that RHT and RHF are safe and can inhibit lung tumor development, with anti-proliferative and pro-apoptotic effects.

Drastic Synergy of Lovastatin and Antrodia camphorata Extract Combination against PC3 Androgen-Refractory Prostate Cancer Cells, Accompanied by AXL and Stemness Molecules Inhibition.

Prostate cancer (PC) is the second most frequently diagnosed cancer and the fifth leading cause of cancer-related death in males worldwide. Early-stage PC patients can benefit from surgical, radiation, and hormonal therapies; however, once the tumor transitions to an androgen-refractory state, the efficacy of treatments diminishes considerably. Recently, the exploration of natural products, particularly dietary phytochemicals, has intensified in response to addressing this prevailing medical challenge. In this study, we uncovered a synergistic effect from combinatorial treatment with lovastatin (an active component in red yeast rice) and Antrodia camphorata (AC, a folk mushroom) extract against PC3 human androgen-refractory PC cells. This combinatorial modality resulted in cell cycle arrest at the G0/G1 phase and induced apoptosis, accompanied by a marked reduction in molecules responsible for cellular proliferation (p-Rb/Rb, Cyclin A, Cyclin D1, and CDK1), aggressiveness (AXL, p-AKT, and survivin), and stemness (SIRT1, Notch1, and c-Myc). In contrast, treatment with either AC or lovastatin alone only exerted limited impacts on the cell cycle, apoptosis, and the aforementioned signaling molecules. Notably, significant reductions in canonical PC stemness markers (CD44 and CD133) were observed in lovastatin/AC-treated PC3 cells. Furthermore, lovastatin and AC have been individually examined for their anti-PC properties. Our findings elucidate a pioneering discovery in the synergistic combinatorial efficacy of AC and clinically viable concentrations of lovastatin on PC3 PC cells, offering novel insights into improving the therapeutic effects of dietary natural products for future strategic design of therapeutics against androgen-refractory prostate cancer.

A meta-analysis of the association between mindfulness and motivation.

Introduction: Mindfulness reflects attention to the present moment in a non-judgmental way and has been linked to individual autonomy and motivation, but conclusions are inconsistent. The purpose of this review was to summarize previous studies to explore the relationship between mindfulness and motivation and its intervention effects. Methods: Literature searches were conducted in five electronic databases. Both correlational studies assessing the association between motivation and mindfulness and experimental studies to verify the effect of intervention were included. Results: Six papers with seven intervention studies and twenty-three papers with twenty-seven correlational studies met the inclusion criteria. Meta-analysis showed that mindfulness was positively correlated with intrinsic motivation (r = 0.28, p < 0.0001) and total motivation (r = 0.37, p < 0.0001) but had no significant correlation with extrinsic motivation (r = 0.01, p = 0.93) or amotivation (r = -0.17, p = 0.14). Effect-size estimates suggested that mindfulness intervention was beneficial to motivation promotion, but the effect was at a low level (g = 0.12). Conclusion: We found consistent support for mindfulness practice relating to motivation promotion, especially on intrinsic motivation development. However, there was still a portion of heterogeneity that could not be explained and needed to be identified in future studies.

Herbal Medicines as Adjuvants for the Treatment of Chemotherapy-Induced Diarrhea.

BACKGROUND: Chemotherapeutic drugs used in cancer treatment often result in gastrointestinal toxicity, notably diarrhea, impacting patients' quality of life. Complementary and Alternative Medicine (CAM) has garnered increasing interest as an alternative to conventional approaches as a potential solution for managing chemotherapyinduced diarrhea (CID). OBJECTIVE: To summarize current research focusing on herbal medicines as adjuvant therapy to prevent or treat chemotherapy-induced diarrhea, including clinical assessments, mechanism of actions, active components, and potential pharmacokinetic interactions between herbal medicines and chemotherapeutic drugs. METHODS: We performed the literature review from PubMed, CNKI, Google Scholar, Web of Science, and Scopus using "Chemotherapy", "Diarrhea," and "Complementary and Alternative Medicine" as the search keywords. RESULTS: Using herbal medicines as adjuvants provides an effective approach to treating or preventing CID with improved or unaffected antitumor activity of chemotherapeutic drugs. Among these herbal formulations, scutellaria, ginger, and ginseng are the most frequently used herbs in the prescriptions for CID. The main antidiarrheal components in herbs include wogonin, baicalin, chrysin, quercetin, gingerol, and ginsenosides. These herbs, formulations, and bioactive components relieved CID through different mechanisms, including directly decreasing local drug exposure, anti-inflammation, inhibiting epithelial apoptosis, or promoting epithelium stem cell regeneration. The application of herbal medicines as adjunctive therapies showed efficacy in preventing or treating CID in multiple clinical trials. However, more well-designed clinical studies are expected to validate the results further. Despite some clinical studies demonstrating that certain herbal medicines could potentially attenuate CID and improve efficacy, it remains necessary to evaluate herbal safety. The interactions between herbs and drugs are also potential concerns, but few clinical trials have focused on investigating this aspect. CONCLUSION: In clinical practise, herbal medications show potential as adjuvant treatments for gastrointestinal toxicities induced by chemotherapy, particularly diarrhoea. Further well-designed clinical studies are needed to validate their efficacy, ensure safety, and explore potential drug-herb interactions.

Development of a Completely New PFOS Alternative with Lower Surface Tension for Minimizing the Environmental Burden.

Improving the technical performance of related industrial products is an efficient strategy to reducing the application quantities and environmental burden for toxic chemicals. A novel polyfluoroalkyl surfactant potassium 1,1,2,2,3,3,4,4-octafluoro-4-(perfluorobutoxy)butane-1-sulfonate(F404) was synthesized by a commercializable route. It had a surface tension(γ) of 18.2 mN/m at the critical micelle concentration(CMC, 1.04 g/L), significantly lower than that of perfluorooctane sulfonate(PFOS, ca. 33.0 mN/m, 0.72 g/L), and exhibited remarkable suppression of chromium-fog at a dose half that of PFOS. The half maximal inhibitory concentration(IC50) values in HepG2 cells and the lethal concentration of 50%(LC50) in zebrafish embryos after 72 hpf indicated a lower toxicity for F404 in comparison to PFOS. In a UV/sulphite system, 89.3% of F404 were decomposed after 3 h, representing a defluorination efficiency of 43%. The cleavage of the ether C-O bond during the decomposition would be expected to form a short chain·C4F9 as the position of the ether C-O in the F404 fluorocarbon chains is C4-O5. The ether unit is introduced in the perfluoroalkyl chain to improve water solubility, biocompatibility and degradation, thereby minimizing the environmental burden.

The efficacy of oral vitamin D supplements on fusion outcome in patients receiving elective lumbar spinal fusion-a randomized control trial.

BACKGROUND: Previous studies have reported that vitamin D supplement could improve fracture healing, but evidence regarding the role of vitamin D supplements in spinal fusion was limited. Thus, this study aimed to evaluate the effectiveness of oral vitamin D supplements on fusion outcomes in patients undergoing lumbar spinal fusion. METHODS: This randomized, double-blind, parallel-designed, active-control trial included the patients who planned for elective lumbar spinal fusion. Eligible patients were randomly assigned to receive either daily vitamin D3 (cholecalciferol) 800 IU and daily calcium citrate 600 mg (experimental group) or only daily calcium citrate 600 mg (control group). All supplements were given from postoperative day 1 and lasted for 3 months. Primary outcome was postoperative 1-year fusion rate, and secondary outcomes included time to fusion, Oswestry Disability Index (ODI), and visual analogue scale (VAS) for pain. RESULTS: Among the included 34 patients (21 in the experimental group and 13 in the control group), baseline 25-hydroxyvitamin D (25[OHVitD) level was 26.7 (10.4) ng/ml. Preoperative prevalence of vitamin D deficiency and insufficiency were 23.5% and 47.1%, respectively. Postoperative 1-year fusion rate was not significantly different between the two groups (95.2% vs. 84.6%, P = 0.544). The experimental group had significantly shorter time to fusion (Kaplan-Meier estimated: 169 days vs. 185 days [interquartile range: 88-182 days vs. 176-324 days], log-rank test: P = 0.028), lower postoperative 6-month ODI (P < 0.001), and lower postoperative 6-month VAS (P < 0.001) than the control group. Time to fusion was significantly and negatively correlated with preoperative, postoperative 3-month, and 6-month 25(OH)VitD levels (all P < 0.01). CONCLUSION: The patient with vitamin D supplements had shorter time to fusion, better spinal function and less pain after elective spinal fusion. Further research is warranted to identify the patients who can benefit the most from vitamin D supplements and the appropriate dose of vitamin D supplements.

Intervention Effects of Okra Extract on Brain-Gut Peptides and Intestinal Microorganisms in Sleep Deprivation Rats.

Objective: Okra, possessing various bioactive components, is used to treat different diseases. This study sought to estimate the intervention effects of okra extract (OE) on brain-gut peptides (BGPs) and intestinal microorganisms in sleep deprivation (SD) rats. Methods: SD rat models were established using the modified multiple platform method and then treated with normal saline, diazepam tablets, or different doses of OE. Body weight and average daily water consumption of rats were recorded. Depressive behaviors of rats were assessed by the open field test and sucrose preference test. Serum levels of noradrenaline, melatonin, inflammatory factors (IL-1ß/IL-6/TNF-α/IL-4/IL-10), and BGP indexes, including gastrin (GAS), motilin (MTL), 5-hydroxytryptamine (5-HT), cholecystokinin (CCK), and vasoactive intestinal peptide (VIP) were measured by ELISA. Additionally, the DNA relative contents of representative intestinal microorganisms in the collected rat feces were determined using RT-qPCR. Results: SD decreased body weight and average daily water consumption and induced depressive behaviors as well as stress and inflammatory responses in rats. SD rats exhibited lowered GAS, MTL, 5-HT, and VIP but elevated CCK and showed diminished DNA relative contents of Bacteroidetes and probiotics (Bifidobacteria and Lactobacilli) but increased Clostridium perfringens. OE at different doses ameliorated the depressive behaviors and mitigated the stress and inflammatory responses in SD rats, raised the serum contents of GAS, MTL, 5-HT, and VIP, reduced CCK level, elevated the DNA relative contents of Bacteroidetes and probiotics, but diminished Clostridium perfringens. OE exhibited similar intervention effects to diazepam tablets (positive control). Conclusion: OE exerts intervention effects on BGPs and intestinal microorganisms in SD rats.

Case report: Significant relief of linezolid-induced peripheral neuropathy in a pre-XDR-TB case after acupuncture treatment.

The revised WHO guidelines on multidrug- or rifampicin-resistant tuberculosis (MDR/RR-TB) include linezolid in the core drug group. Common adverse events of prolonged linezolid use are bone marrow suppression and peripheral neuropathy (PN). Available measures against linezolid-induced PN (LIPN) often have insignificant effects, leading to linezolid discontinuation and a decline in the success rate of MDR/RR-TB treatment. Acupuncture treatment is a symptomatic treatment measure from traditional Chinese medicine (TCM) to relieve pain with overall very low evidence and has never been reported in LIPN. The pilot use of acupuncture in a pre-extensively drug-resistant (XDR)-TB (a more severe form of MDR/RR-TB) patient exhibited significant improvements in LIPN and thus maintained linezolid in the regimen for a longer period.

Cost-Effectiveness Analysis of the TCM "Yupingfeng Granules" in the Treatment of Acute Exacerbations of COPD Based on a Randomized Clinical Trial.

Introduction: Traditional Chinese medicine (TCM) is becoming increasingly important as it provides further options for treating many diseases worldwide. The TCM "Yupingfeng" has been used in China for over 800 years, and its clinical efficacy and safety for COPD treatment have been proven in previous studies. The objective of this study was to compare the long-term cost-effectiveness of Yupingfeng granules and the current conventional treatment for COPD patients in China. Methods: A Markov model was constructed from the perspective of the Chinese healthcare system using TreeAge Pro 2011. The model cycle length was 12 months, and the cycle time was set to 10 years. Data from a randomized controlled trial were used to generate the number of acute exacerbations, COPD assessment test (CAT) score and actual medication used. The state transition probabilities, costs and quality-adjusted life years (QALYs) were derived from available sources. A threshold of 72,447 yuan per QALY gained was used as a cost-effectiveness criterion. One-way and probabilistic sensitivity analyses were conducted to verify the model. In addition, the cost-effectiveness of a 35-year cycle was evaluated as a scenario analysis. Results: In the basic-case analysis, the ICER of adding Yupingfeng granules to the current conventional treatment drugs was ¥2123.04 per QALY, which was less than the threshold (one-time per capita GDP).Sensitivity analyses showed the results to be robust. Probabilistic sensitivity analysis showed that the probability of the ICER being less than the one-time per capita GDP threshold was 100%. In the scenario analysis, the incremental cost-effectiveness was ¥12,051.27 per QALY which was also under the one-time per capita GDP. Conclusion: By reducing the number of acute exacerbations of COPD, thereby correspondingly reducing the follow-up treatment cost, Yupingfeng granules combined with conventional treatment were found to provide a cost-effective therapeutic strategy for COPD.

Selenium Yeast and Fish Oil Combination Diminishes Cancer Stem Cell Traits and Reverses Cisplatin Resistance in A549 Sphere Cells.

Cisplatin is a prevalent chemotherapeutic agent used for non-small cell lung cancer (NSCLC) that is difficult to treat by targeted therapy, but the emergence of resistance severely limits its efficacy. Thus, an effective strategy to combat cisplatin resistance is required. This study demonstrated that, at clinically achievable concentrations, the combination of selenium yeast (Se-Y) and fish oil (FO) could synergistically induce the apoptosis of cancer stem cell (CSC)-like A549 NSCLC sphere cells, accompanied by a reversal of their resistance to cisplatin. Compared to parental A549 cells, sphere cells have higher cisplatin resistance and possess elevated CSC markers (CD133 and ABCG2), epithelial-mesenchymal transition markers (anexelekto (AXL), vimentin, and N-cadherin), and cytoprotective endoplasmic reticulum (ER) stress marker (glucose-regulated protein 78) and increased oncogenic drivers, such as yes-associated protein, transcriptional coactivator with PDZ-binding motif, ß-catenin, and cyclooxygenase-2. In contrast, the proapoptotic ER stress marker CCAAT/enhancer-binding protein homologous protein and AMP-activated protein kinase (AMPK) activity were reduced in sphere cells. The Se-Y and FO combination synergistically counteracted the above molecular features of A549 sphere cells and diminished their elevated CSC-like side population. AMPK inhibition by compound C restored the side population proportion diminished by this nutrient combination. The results suggest that the Se-Y and FO combination can potentially improve the outcome of cisplatin-treated NSCLC with phenotypes such as A549 cells.

Lactobacillus pentosus Alleviates Lipopolysaccharide-Induced Neuronal Pyroptosis via Promoting BIRC3-Mediated Inactivation of NLRC4.

Objective: Neurodegenerative disease is a common neurodegenerative disorder. Lactobacillus pentosus (L. pentosus) plays a neuron-protective role. This study aimed to investigate the effects of L. pentosus on neurodegenerative diseases. Methods: Cells were treated with lipopolysaccharide (LPS) to establish neurodegenerative diseases model in vivo and with L. pentosus strain S-PT84. Reverse transcription-quantitative PCR (RT-qPCR) was applied to determine mRNA levels. Western blot was performed to detect protein expression. Cellular behaviors were detected using Cell Counting Kit-8 (CCK-8), flow cytometry, and TdT-mediated dUTP nick-end labeling (TUNEL) assay. The interaction between baculoviral IAP repeat containing 3 (BIRC3) and NLR family CARD domain containing 4 (NLRC4) was predicted by STING and verified by western blot. Result: L. pentosus suppressed LPS-induced pyroptosis and promoted the cell viability of neurons. Additionally, L. pentosus suppressed the release of proinflammatory cytokines (interleukin 1 beta (IL-1ß) and IL-18) and the protein expression of pyroptosis biomarkers (cleaved caspase1 (CL-CASP1) and N-terminal fragment gasdermin D (GSDMD-N)). Moreover, L. pentosus upregulated BIRC3, which induced the inactivation of NLRC4. However, BIRC3 knockdown alleviated the effects of L. pentosus and induced neuronal degeneration. Conclusion: L. pentosus may play a neuron-protective role via regulating BIRC3/NLRC4 signaling pathways. Therefore, L. pentosus may be a promising strategy for neurodegenerative diseases.

Metabolomics analysis reveals the renal protective effect of Panax ginseng C. A. Mey in type 1 diabetic rats.

The dry root and rhizome of Panax ginseng C. A. Mey has garnered much interest owing to its medicinal properties against diabetes and cardiovascular diseases. In this study, an ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS)-based metabolomics approach was used to illustrate the therapeutic mechanisms of ginseng extract on the serum and urinary metabolic profiles in streptozotocin-induced type 1 diabetes mellitus (T1DM) rats. Pharmacological and renal parameters in response to the administration of ginseng were also evaluated. In total, 16 serum endogenous metabolites and 14 urine endogenous metabolites, including pyruvic acid, indoleacetic acid, and phenylacetylglycine, were identified as potential biomarkers for diabetes. Pathway enrichment and network analysis revealed that the biomarkers modulated by ginseng were primarily involved in phenylalanine and pyruvate metabolism, as well as in arginine biosynthesis. Moreover, the levels of several renal injury-related biomarkers in T1DM rats were significantly restored following treatment with ginseng. The administration of the extract helped maintain tissue structure integrity and ameliorated renal injury. The findings suggest that the regulatory effect of ginseng extract on T1DM involves metabolic management of diabetic rats, which subsequently attenuates T1DM-induced early renal dysfunction.

Systematic analysis of tRNA-derived small RNAs reveals therapeutic targets of Xuefu Zhuyu decoction in the cortexes of experimental traumatic brain injury.

BACKGROUND: Xuefu Zhuyu Decoction (XFZYD), a well-known traditional Chinese medicine prescription, has been widely used to treat traumatic brain injury (TBI). However, the underlying mechanisms involved in XFZYD therapy remain unclear. AIM OF THE STUDY: We explored new therapeutic targets of XFZYD in TBI by the tsRNA-sequencing (tsRNA-seq) method. MATERIAL AND METHODS: High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to assess the quality of XFZYD. Male Sprague-Dawley rats were randomly categorized into three groups: sham, TBI, and XFZYD. The protective effects of XFZYD were investigated in vivo by using the Morris water maze (MWM), modified neurological severity score (mNSS) tests, hematoxylin-eosin (H&E) staining, and Nissl staining. tsRNA-seq was applied to analyze the expression of tsRNAs in the rat cortex. Four tsRNAs were validated by qRT-PCR. The biological function of putative tsRNAs was investigated using bioinformatics techniques. The functions of tsRNAs targeting mRNAs were verified in vitro. RESULTS: The mNSS and MWM indicated that XFZYD notably improved neurological deficits and cognitive function after TBI (p < 0.05). H&E staining and Nissl staining demonstrated that XFZYD suppressed damage and neuronal loss in the TBI rat cortex. We evaluated the dysregulated expression of 732 tsRNAs (128 tsRNAs were significantly altered in the TBI/sham group (fold change > 2 and p < 0.05), and 97 tsRNAs were dysregulated in the XFZYD/TBI group (fold change > 2 and p < 0.05)) in the TBI rat cortex. Interestingly, 41 tsRNAs were distinctly regulated by XFZYD. The qRT-PCR results of the four randomly chosen tsRNAs (tRF-54-75-Glu-TTC-2, tRF-55-75-Gln-CTG-2-M2, tRF-55-76-Val-TAC-1, tRF-64-85-Leu-AAG-1-M4) exhibited trends similar to those of the tsRNA-seq data. We certified the possible targets of tsRNAs and suggested the crosscurrent in the expression trend of the target genes. Bioinformatics analysis showed that XFZYD-related tsRNAs could contribute to regulating insulin resistance, the calcium signaling pathway, autophagy, and axon guidance. CONCLUSIONS: The current research implies that tsRNAs are putative therapeutic targets of XFYZD for TBI treatment. This research provides new insight into the therapeutic targets of XFZYD in treating TBI.

Phosphate and Cellular Senescence.

Cellular senescence is one type of permeant arrest of cell growth and one of increasingly recognized contributor to aging and age-associated disease. High phosphate and low Klotho individually and synergistically lead to age-related degeneration in multiple organs. Substantial evidence supports the causality of high phosphate in cellular senescence, and potential contribution to human aging, cancer, cardiovascular, kidney, neurodegenerative, and musculoskeletal diseases. Phosphate can induce cellular senescence both by direct phosphotoxicity, and indirectly through downregulation of Klotho and upregulation of plasminogen activator inhibitor-1. Restriction of dietary phosphate intake and blockage of intestinal absorption of phosphate help suppress cellular senescence. Supplementation of Klotho protein, cellular senescence inhibitor, and removal of senescent cells with senolytic agents are potential novel strategies to attenuate phosphate-induced cellular senescence, retard aging, and ameliorate age-associated, and phosphate-induced disorders.

Acupuncture for Quality of Life in Gastric Cancer Patients Undergoing Adjuvant Chemotherapy.

CONTEXT: Patients with gastric cancer experience health-related quality of life (HRQOL) decline during adjuvant chemotherapy following gastrectomy. OBJECTIVES: This pilot study aimed to evaluate the preliminary effect and feasibility of electro-acupuncture (EA) for HRQOL and symptom burden in these patients. METHODS: In this open-label, multicenter, parallel controlled trial, gastric cancer patients who planned to receive adjuvant chemotherapy were randomly assigned to receive high-dose EA (seven times each chemotherapy cycle for three cycles), low-dose EA (three times each chemotherapy cycle), or usual care only. The acupoints prescription consisted of bilateral ST36, PC6, SP4, and DU20, EX-HN3, and selected Back-shu points. Patients completed the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga) weekly, and the Edmonton Symptom Assessment System (ESAS). The primary outcome was the difference among the groups on the gastric cancer subscale (GaCS) of the FACT-Ga. RESULTS: Of the 66 randomized patients, 58 were analyzed according to intention-to-treat principle, and 45 were in the per-protocol set (PPS). The average scores in PPS of GaCS were 52.12±9.71, 51.85±12.36, and 45.37±8.61 in high-dose EA, low-dose EA, and control groups, respectively. EA was significantly associated with improved average GaCS scores when compared with control group (51.98±10.91 vs. 45.37±8.61, P = 0.039). EA treatment also produced ESAS relief at the end of intervention (14.36 ± 12.28 vs. 23.91 ± 15.52, P = 0.027). Participants in EA groups had fewer grade ≥3 leukopenia (0% vs. 15.79%, P = 0.031) and neutropenia (2.56% vs. 26.31%, P = 0.012). CONCLUSION: EA showed promising effects in improving HRQOL, controlling symptom burden, and reducing toxicity during adjuvant chemotherapy in gastric cancer patients. Future adequately powered trials are feasible and needed to confirm the specific effect of EA.

Clinical application of traditional Chinese medicine moisture exposed burn ointment in the treatment of facial soft tissue defect.

OBJECTIVE: To introduce a new method of treating facial soft tissue defect by observing the clinical curative effects of traditional Chinese medicine moisture exposed burn ointment in treating facial soft tissue defect. METHODS: A total of 85 patients with facial soft tissue defects were treated with traditional Chinese medicine moisture exposed burn ointment, and the clinical therapeutic effects were analyzed by observing the wound healing time, scar formation and changes of facial appearance and functions. RESULTS: Of the 85 patients, the shortest wound healing time was 12 days and the longest was 72 days; the facial appearance and functions restored to be normal in 74 patients, with good skin elasticity and mild scar formation in the wound area; 11 patients were lost to the follow-up; two patients suffered from the longest wound healing time due to their skin defect of nasal tip and nasal columella and the cartilage defect of nasal wings, and V-shaped defects were left at the edge of the left nostrils after the wound healing, which may be attributed to the ineffectiveness of MEBT/MEBO on cartilage. CONCLUSION: Traditional Chinese medicine moisture exposed burn ointment can realize more satisfying healing effects when applied in the treatment of facial soft tissue defects, including user-friendly operation, no special requirements for medical devices, obviously lower treatment cost, etc., and thus it is an easy-to-operate and effective way for such patients, especially for elderly patients, patients with poor body conditions and patients unbearable to undergo complicated operations.

Pharmacokinetic Characterization and Bioavailability Barrier for the Key Active Components of Botanical Drug Antitumor B (ATB) in Mice for Chemoprevention of Oral Cancer.

This study aims to characterize the pharmacokinetic (PK) profiles and identify important bioavailability barriers and pharmacological pathways of the key active components (KACs) of Antitumor B (ATB), a chemopreventive agent. KACs (matrine, dictamine, fraxinellone, and maackiain) of ATB were confirmed using the antiproliferative assay and COX-2 inhibition activities in oral cancer cells. The observed in vitro activities of KACs were consistent with their cell signaling pathways predicted using the in silico network pharmacology approach. The pharmacokinetics of KACs were determined after i.v., i.p., and p.o. delivery using ATB extract and a mixture of four KACs in mice. Despite good solubilities and permeabilities, poor oral bioavailabilities were estimated for all KACs, mostly because of first-pass metabolism in the liver (for all KACs) and intestines (for matrine and fraxinellone). Multiple-dose PK studies showed 23.2-fold and 8.5-fold accumulation of dictamine and maackiain in the blood, respectively. Moreover, saliva levels of dictamine and matrine were found significantly higher than their blood levels. In conclusion, the systemic bioavailabilities of ATB-KACs were low, but significant levels of dictamine and matrine were found in saliva upon repeated oral administration. Significant salivary concentrations of matrine justified its possible use as a drug-monitoring tool to track patient compliance during chemoprevention trials.
