Surrounding Needling and Narrowband Ultraviolet B Phototherapy Treatment: Synergistic Effects for Repigmentation in Chronic, Stable Nonsegmental Vitiligo.

Context: Narrowband ultraviolet B (NBUVB) phototherapy is the standard treatment for chronic stable vitiligo, but its efficacy, when used alone, is often unsatisfactory. Objective: The study evaluated the efficacy of surrounding needling with acupuncture needles in combination with NBUVB phototherapy for lesions on different body parts of patients with chronic stable vitiligo. Design: The research team designed a 12-week, randomized, open-label, prospective, intra-individual, comparative clinical trial. Setting: The study took place in the Department of Dermatology at Shin-Kong Wu Ho-Su Memorial Hospital in Taiwan. Participants: Participants were patients at the hospital, aged 20-80 years, with chronic stable nonsegmental vitiligo. The lesions on both sides of their bodies had the same baseline conditions. Nine patients with 14 pairs of lesions (n = 28) were included in the study, and eight participants with 13 pairs of lesions (n = 26) successfully completed the study. Intervention: Vitiligo lesions in the intervention group were treated with surrounding needling combined with NBUVB phototherapy, whereas the control group received NBUVB phototherapy only. Outcome Measures: The primary outcome was evaluated at Week 12 using the modified Vitiligo Area Scoring Index (VASI), which focuses on local depigmentation only without multiplication by body surface area, and the testing used the Wilcoxon signed-rank test. A higher VASI score indicates more severe vitiligo. Pain was rated postintervention, after completion of all treatments. Results: At baseline, the modified VASI score in both groups was 93.07 ± 4.62. Postintervention, this score in the intervention group improved to 78.46 ± 15.24, with a significant difference between baseline and postintervention (P = .007), and in the control group, the score improved to 91.92 ± 6.67, with no significant difference having occurred (P = .317). A statistically significant difference was found between the intervention group and the control group in the change in scores postintervention (P = .007). Conclusion: Surrounding needling in combination with NBUVB phototherapy may be a promising treatment for chronic stable nonsegmental vitiligo. Future studies with larger sample sizes and long-term follow-up are warranted.

Chinese Herbal Fumigation Steam Therapy and Acupuncture in the Treatment of Knee Osteoarthritis: A Three-armed, Randomized, Controlled Trial.

Context: Knee osteoarthritis is a common form of joint disease found in humans and one of the leading causes of disability globally. Knee osteoarthritis (KOA) is responsible for a higher number of disabilities than any other medical condition affecting activities of daily living (ADL). To date no definitive, conventional medical protocol is available to deal with KOA. Objectives: The study intended to clinically investigate whether the benefits of acupuncture in the treatment of KOA) could be augmented by the addition of Chinese herbal fumigation steam therapy (CHFST) to the treatment protocol and to what degree it had benefits. Design: The research team designed a three-armed, randomized, controlled trial. The sample size was determined by analysis of power; for a sample size of 42, the power was 83.5%; the effect size was 0.5; and the α was 0.05. Setting: The setting was the traumatology department in the Chinese Medicine Branch of Taipei City Joint Hospital in Kun Ming, Taiwan. Participants: Participants were 45 males and females between the ages of 35 and 75, who were patients in the traumatology department and who were suffering from bilateral knee osteoarthritis. Three participants were lost to follow-up. Interventions: Participants were randomly assigned to one of three groups, each with 15 participants; (1) the control group, who received acupuncture only; (2) the normal CHFST group, an intervention group who received acupuncture plus a normal dose of CHFST; and (3) the one-sixteenth CHFST group, an intervention group who received acupuncture plus one-sixteenth of a normal dose of CHFST. Participants underwent biweekly treatments for four consecutive weeks. Outcomes Measures: The primary outcome measures included a visual analog scale (VAS) to assess variations in pain intensity and a goniometer measure for range of motion (ROM). Results: The addition of CHFST to acupuncture in the treatment of KOA significantly reduced pain (P = .0017) for the normal CHFST group compared to the control group and the one-sixteenth CHFST group. Chinese medical interventions overall for all groups showed a decrease in pain and increases in ROM, and health related quality of life (HrQoL). Conclusions: CHFST, in conjunction with acupuncture, showed promise in the treatment of KOA in reducing pain, increasing ROM, and improving quality of life (QoL).

Proteomic Profiling of Aqueous Humor Exosomes from Age-related Macular Degeneration Patients.

Purpose: The alteration of the exosomal proteins in the aqueous humor (AH) is linked to the development of eye diseases. The goal of this study was to examine the exosomal protein profile of patients with age-related macular degeneration (AMD) to better understand their role in the pathogenesis of AMD. Methods: Exosomes were isolated from the AH of 28 AMD and 25 control eyes. The quality, concentration, and size distribution of exosomes were measured using a nanoparticle tracking analysis system (NTA). Total exosomal proteins from each sample were purified and digested with trypsin for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. Results: Based on LC-MS/MS analysis, we got 105 exosomal peptides from AMD and control patients. Gene ontology (GO) analysis in the biology process revealed that exosomal proteins of AMD were enriched in the lipoprotein metabolic process. T-test analysis revealed six exosomal proteins in patients with AMD were significantly different from controls. Comparing the exosomal protein profile of AMD patients who were receiving anti-VEGF therapy, we observed the amount of two proteins decreased with the duration of the anti-VEGF treatment time. Conclusions: In this study, we successfully isolated and purified AH exosomes. Our results provide pioneering findings for the exosomal protein profile in AMD development and under therapy. These unique proteins could be the new targets for drug discovery or biological markers for evaluating therapeutic efficacy.

Modulation of Gut Microbiota Combined with Upregulation of Intestinal Tight Junction Explains Anti-Inflammatory Effect of Corylin on Colitis-Associated Cancer in Mice.

Inflammatory bowel disease (IBD) involves chronic inflammation, loss of epithelial integrity, and gastrointestinal microbiota dysbiosis, resulting in the development of a colon cancer known as colitis-associated colorectal cancer (CAC). In this study, we evaluated the effects of corylin in a mouse model of dextran sodium sulfate (DSS)-induced colitis. The results showed corylin could improved the survival rate and colon length, maintained body weight, and ameliorated the inflammatory response in the colon. Then, we further identified the possible antitumor effects after 30-day treatment of corylin on an azoxymethane (AOM)/DSS-induced CAC mouse model. Biomarkers associated with inflammation, the colon tissue barrier, macrophage polarization (CD11c, CCR7, CD163, and CD206), and microbiota dysbiosis were monitored in the AOM/DSS group versus corylin groups. Corylin downregulated pro-inflammatory cytokines (TNF-α, IFN-γ, IL-1ß, and IL-6) mRNA expression and inflammatory signaling-associated markers (TLR4, MyD88, AP-1, CD11b, and F4/80). In addition, a colon barrier experiment revealed that epithelial cell proliferation of the mucus layer (Lgr5, Cyclin D1, and Olfm4) was downregulated and tight junction proteins (claudin-1 and ZO-1) were upregulated. Furthermore, the Firmicutes/Bacteroidetes ratio changed with corylin intervention, and the microbial diversity and community richness of the AOM/DSS mice were improved by corylin. The comparative analysis of gut microbiota revealed that Bacteroidetes, Patescibacteria, Candidatus Saccharimonas, Erysipelatoclostridium, and Enterorhabdus were significantly increased but Firmicutes, Turicibacter, Romboutsia, and Blautia decreased after corylin treatment. Altogether, corylin administration showed cancer-ameliorating effects by reducing the risk of colitis-associated colon cancer via regulation of inflammation, carcinogenesis, and compositional change of gut microbiota. Therefore, corylin could be a novel, potential health-protective, natural agent against CAC.

Proteomic analysis of Exosomes derived from the Aqueous Humor of Myopia Patients.

Objectives: Myopia is the most common refractive vision disorder. In recent years, several studies have suggested that the alteration of the exosomal protein levels in the aqueous humor (AH) is associated with the development of several eye diseases. Therefore, we aimed to explore the exosomal protein profile of the AH from myopia patients. Methods: Exosomes were isolated from the AH. The quality, concentration, and size distribution of exosomes for each patient were measured using nanoparticle tracking analysis system. Then, the exosomal proteins were purified and digested by trypsin for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. Results: There was no significant difference observed between the myopia and control when comparing the concentration and size distribution of exosomes in the AH for each sample. Based on LC-MS/MS analysis, myopia patients had higher and more complex exosomal peptide content. We found two proteins that were common in AH exosomes and eight proteins that were highly expressed in the myopia group. Conclusions: Our results provide pioneering findings for the exploration of the exosomal protein profile in myopia development. Further studies may provide significant information for the diagnosis, clinical treatment, and prognosis of myopia.

The Efficacy of Combined Electroacupuncture and Auricular Pressure on Sleep Quality in Patients Receiving Methadone Maintenance Treatment.

BACKGROUND AND OBJECTIVES: Previous studies have revealed that the electroacupuncture or auricular-point pressure as a single treatment approach is beneficial for relieving insomniac symptoms among patients under methadone maintenance treatment (MMT). This study is designed to evaluate the clinical efficacy of combining two treatments. METHODS: This study was a randomized, controlled, crossover trial. A total of 50 participants were recruited from the Linsen Chinese Medicine and Kunming Branches of Taipei City Hospital and randomly assigned to Groups A (25 participants) and B (25 participants). In Group A (electroacupuncture at the Hegu point (LI4) and Zusanli point (ST36) and auricular-point pressure on the Shenmen point) and Group B (only auricular-point), the interventions were implemented biweekly for 4 weeks. After a 1-week washout period, a crossover of the groups was performed. Sleep quality, according to the Pittsburgh Sleep Quality Index (PSQI), and daily attendance rate of MMT were evaluated. RESULTS: Combined therapy significantly improved sleep quality, especially in the PSQI subscales of subjective sleep quality (60.91% vs 20.93%, P < 0.05) and sleep latency (42.59% vs 11.28%, P < 0.05). A significantly higher daily attendance rate was noted in combined therapy than single therapy (87% ± 2% vs 82% ± 2%, P < 0.001). DISCUSSION AND CONCLUSIONS: The combination of the electroacupuncture with auricular-point pressure demonstrated high efficacy for improving sleep quality and increasing MMT adherence compared with single therapy of auricular-point pressure. SCIENTIFIC SIGNIFICANCE: Combined therapy of the electroacupuncture and auricular-point pressing should be introduced as a routine, facilitating treatment for patients under methadone maintenance.

Miconazole induces protective autophagy in bladder cancer cells.

Autophagy plays a dual function in cancer progression; autophagy activation can support cancer cell survival or contribute to cell death. Miconazole, a Food and Drug Administration-approved antifungal drug, has been implicated in oncology research recently. Miconazole was found to exert antitumor effects in various tumors, including bladder cancer (BC). However, whether it provokes protective autophagy has been never discussed. We provide evidence that miconazole induces protective autophagy in BC for the first time. The results indicated that 1A/1B-light chain 3 (LC3)-II processing and p62 expression were elevated after miconazole exposure. Also, adenosine monophosphate-activated protein kinase phosphorylation was increased after miconazole treatment. We also confirmed the autophagy-promoting effect of miconazole in the presence of bafilomycin A1 (Baf A1). The result indicates that a combination treatment of miconazole and Baf A1 improved LC3-II processing, confirming that miconazole promoted autophagic flux. The acridine orange, Lysotracker, and cathepsin D staining results indicate that miconazole increased lysosome formation, revealing its autophagy-promoting function. Finally, miconazole and autophagy inhibitor 3-methyladenine cotreatment further reduced the cell viability and induced apoptosis in BC cells, proving that miconazole provokes protective autophagy in BC cells. Our findings approve that miconazole has an antitumor effect in promoting cell apoptosis; however, its function of protective autophagy is needed to be concerned in cancer treatment.

Diterpenoid Compounds Isolated from Chloranthus oldhamii Solms Exert Anti-Inflammatory Effects by Inhibiting the IKK/NF-κB Pathway.

Chloranthus oldhamii Solms (CO) is a folk medicine for treating infection and arthritis pain but its pharmacological activity and bioactive compounds remain mostly uncharacterized. In this study, the anti-inflammatory compounds of C. oldhamii were identified using an LPS-stimulated, NF-κB-responsive RAW 264.7 macrophage reporter line. Three diterpenoid compounds, 3α-hydroxy-ent-abieta-8,11,13-triene (CO-9), 3α, 7ß-dihydroxy-ent-abieta-8,11,13-triene (CO-10), and decandrin B (CO-15) were found to inhibit NF-κB activity at nontoxic concentrations. Moreover, CO-9 and CO-10 suppressed the expression of IL-6 and TNF-α in LPS-stimulated RAW 264.7 cells. The inhibitory effect of CO-9 on TNF-α and IL-6 expression was further demonstrated using LPS-treated bone marrow-derived macrophages. Furthermore, CO-9, CO-10, and CO-15 suppressed LPS-triggered COX-2 expression and downstream PGE2 production in RAW 264.7 cells. CO-9 and CO-10 also reduced LPS-triggered iNOS expression and nitrogen oxide production in RAW 264.7 cells. The anti-inflammatory mechanism of the most effective compound, CO-9, was further investigated. CO-9 attenuated LPS-induced NF-κB activation by reducing the phosphorylation of IKKα/ß (Ser176/180), IκBα (Ser32), and p65 (Ser534). Conversely, CO-9 did not affect the LPS-induced activation of MAPK signaling pathways. In summary, this study revealed new anti-inflammatory diterpenoid compounds from C. oldhamii and demonstrated that the IKK-mediated NK-κB pathway is the major target of these compounds.

Expression Profiling of Exosomal miRNAs Derived from the Aqueous Humor of Myopia Patients.

Myopia is the most common refractive disorder in Eastern Asia. The development of myopia is associated with the cooperation of various ocular tissues. Exosomes in the aqueous humor (AH) have been implicated to modulate intracellular communications by transferring exosomal miRNAs and proteins between cells. These exosomal miRNAs and proteins are likely involved in the pathogenesis of various eye diseases. In this study, we aimed to explore human exosomal miRNA profiles and their roles in myopia development. AH samples were collected from 16 patients (8 myopia and 8 control) undergoing routine cataract surgeries. Exosomes were isolated from AH of each individual using the ExoQuick solution. The numbers and sizes of exosomes were not significantly different between the myopia and control groups. The individual exosomes of the same group were pooled to purify RNA. Unexpectedly, the myopia group contained 2.78-fold total RNA amount than that in the control group. Thereafter, miRNA profiles were analyzed using the OpenArray system. We thus found 15 myopia-specific miRNAs and four myopia-absent miRNAs. By using bioinformatics analysis, we identified six well-known myopia-associated genes that are potential targets of five myopia-specific miRNAs (has-miR-582-3p, has-miR-17-5p, has-miR-885-3p, has-miR-19b-3p, and has-miR-450b-5p). These genes are cholinergic receptor muscarinic 2 (CHRM2), cyclic nucleotide-gated channel beta 3 (CNGB3), vascular endothelial growth factor A (VEGFA), adenosine A2a receptor (ADORA2A), insulin-like growth factor 1 (IGF1), and lumican (LUM). Moreover, CHRM2 may be a target of myopia-absent miRNA (has-miR-378a-5p). In conclusion, we show the expression profiles of AH-derived exosomal miRNAs and their potential roles in myopia development.

Effects of green tea extract on overweight and obese women with high levels of low density-lipoprotein-cholesterol (LDL-C): a randomised, double-blind, and cross-over placebo-controlled clinical trial.

BACKGROUND: This study aims to examine the effects of green tea extract (GTE) supplement on overweight and obese women with high levels of low density lipoprotein-cholesterol (LDL-C). METHODS: The randomized, double-blind, crossover and placebo-controlled clinical trial was conducted from August 2012 to December 2013. Seventy-three out of 90 subjects aged between 18 and 65 years, with body mass index (BMI) ≥ 27 kg/m2 and LDL-C ≥ 130 mg/dl were included in the analysis. The subjects were randomly divided into Groups A and B. Group A received GTE supplement treatment for the first 6 weeks, while Group B received placebo daily. After 6 weeks of treatment and 14 days of washout period, Group A switched to placebo and Group B switched to GTE treatment for 6 weeks. The reduction of LDL-C level between treatments was assessed as the outcome. Additionally, anthropometric measurements, plasma lipoproteins and hormone peptides of both groups were measure at the beginning of weeks 6, 8, and 14 after treatment. RESULTS: Subjects treated with GTE (n = 73) for 6 weeks showed significant differences, with 4.8% (p = 0.048) reduction in LDL-C and 25.7% (p = 0.046) increase in leptin. However, there was no statistical difference in the levels of total cholesterol, triglyceride and high density lipoprotein between the GTE and placebo groups after treatments. CONCLUSIONS: This study shows that green tea extract effectively increases leptin and reduces LDL in overweight and obese women after 6 weeks of treatment even though there were no significant changes in other biochemical markers related to overweight. TRIAL REGISTRATION: This clinical trial is registered with ClinicalTrials.gov: NCT02116517 on 17 April 2014. Retrospectively registered. The first patient enrolled in October 2012 and the study was completed December 2013.

The efficacy of acupuncture in managing patients with chronic prostatitis/chronic pelvic pain syndrome: A systemic review and meta-analysis.

OBJECTIVES: This study aimed to systemically review published randomized control trials that compared the efficacy of acupuncture with sham acupuncture or standard medical treatment as management for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: A systemic search of the PubMED®, Embase, Airiti Library, and China Journal Net was done for all randomized controlled trials that compared the efficacy of acupuncture with sham acupuncture, alpha-blockers, antibiotics, or anti-inflammatory drugs in patients with CP/CPPS. Two investigators conducted the literature search, quality assessment, and data extraction. The data were then analyzed using the Cochrane Collaboration Review Manager (RevMan®, version 5.3). The study endpoints were response rate, the National Institute of Health-Chronic Prostatitis Index (NIH-CPSI), and the International Prostate symptom score (IPSS) reduction. RESULTS: Three and four randomized controlled trials compared acupuncture with sham acupuncture (n = 101 vs. 103) and medical treatment (n = 156 vs. 138), respectively. The results revealed that acupuncture was superior to sham acupuncture as regards response rate (OR: 5.15, 95%CI: 2.72-9.75; P < 0.01), NIH-CPSI (WMD: -6.09, 95%CI: -7.85 to -4.33), and IPSS (WMD: -2.44, 95%CI: -4.86 to -0.03; P = 0.05) reductions, therefore, excluding the placebo effect. Compared to standard medical treatments, acupuncture had a significantly higher response rate (OR: 3.57, 95%CI: 1.78-7.15; P < 0.01). CONCLUSIONS: Acupuncture has promising efficacy for patients with CP/CPPS. Compared to standard medical treatment, it has better efficacy. Thus, it may also serve as a standard treatment option when available. Neurourol. Urodynam. 36:474-481, 2017. © 2016 Wiley Periodicals, Inc.

Utilization and prescription patterns of traditional Chinese medicine for patients with hepatitis C in Taiwan: a population-based study.

BACKGROUND: To characterize the utilization of Traditional Chinese Medicine (TCM) among patients with hepatitis C (HC). METHODS: This study examined datasets from the National Health Insurance Research Database in Taiwan. One cohort, including one million patients randomly sampled from the beneficiaries of the National Health Insurance Programme from January 1 to December 31 in 2010, was chosen for this analysis. People who had at least three outpatient or inpatient records and had been diagnosed with hepatitis C virus infection from 2000 to 2010 were defined as patients with HC. Patients with HC who had at least one TCM outpatient clinical record from 2000 to 2010 were defined as TCM users (N = 5,691), whereas patients with no TCM outpatient records were defined as non-TCM users (N = 2,876). The demographic data, treatment modalities and disease distributions of TCM users were analysed. RESULTS: Overall, 66.4 % of the patients with HC had used TCM from 2000 to 2010. Of the TCM users, 54.1 % were female. The utilization rate of TCM increased with age and peaked in the age group of those 40 - 64 years old. Herbal remedies (52.4 %) were the most commonly used agents, followed by combination therapy (46.4 %) and acupuncture alone (1.2 %). Patients who had more extrahepatic diseases and were taking more antiviral agents tended to visit TCM clinics. Jia-Wei-Xiao-Yao-San and Dan-Shen (Salvia miltiorrhiza) were the most commonly used formula and single herb, with 88,124 person-days and 59,252 person-days, respectively. CONCLUSIONS: Our nationwide population-based study revealed a high prevalence and specific usage patterns of TCM in patients with HC in Taiwan.

Impact of hypoalphalipoproteinemia on quality of life in Taiwanese women with central obesity.

PURPOSE: To investigate the relationship between health-related quality of life (HRQoL) and different cutoff value of low level of high-density lipoprotein cholesterol (HDL-C) in Taiwanese women with different definition of obesity. METHODS: Prospective observational study in women with central obesity was conducted in Taipei City Hospital. A total of 572 women were screened at our clinic, and 227 of them with a body mass index ≧27 kg/m2 defined by the Department of Health in Taiwan and weight circumference ≧80 cm were eligible for the study. We defined two groups as group A-low HDL (HDL-C < 40 mg/dL) and group B-high HDL (HDL-C < 50 mg/dL) according to different definition of hypoalphalipoproteinemia in obese women. RESULTS: Significantly reduced HRQoL score was noted in group A-low HDL compared to group A-high HDL (HDL-C ≧ 40 mg/dL), but not between group B-low HDL and group B-high HDL (HDL-C ≧ 50 mg/dL). Positively correlation was noted between HDL-C level and physical domain of HRQoL score. HDL-C contributes independently to physical domain of HRQoL score after controlling for other factors. Decreased leptin and adiponectin level were noted in hypoalphalipoproteinemia groups. CONCLUSION: Taiwanese obese women with hypoalphalipoproteinemia have adverse impact on HRQoL, especially when the HDL-C level is lower than 40 mg/dL. Both hypoalphalipoproteinemia and hypertension accounted for a great variance to lower scores of physical domain of HRQoL with positively correlation with HDL-C level observed. Decreased leptin and adiponectin were also observed in hypoalphalipoproteinemia group, which implied increased cardiovascular risk. HDL-C level may deem as another indicator for HRQoL in women with central obesity.

Effects of Kuan-Sin-Yin decoction on immunomodulation and tumorigenesis in mouse tumor models.

BACKGROUND: Complementary therapies are widely used among cancer patients. Kuan-Sin-Yin (KSY) decoction, a popular qi-promoting herbal medicine, was constituted with several herbs known to exhibit immunomodulating or anticancer activity. After combining these herbs as a compound formula, it is necessary to reassess the immunomodulation effects, the effects on tumor growth, and possible toxicity of KSY. METHODS: The anti-cancer effects of KSY in vivo were determined by measuring the tumor volumes, anticancer-associated cytokines (IFN-gamma, TNF-alpha, IL-2, and IL-12), accumulation of tumor infiltrating leukocytes (TILs), proliferation and apoptosis-related molecular markers (Ki-67, p53, p21, activated caspase 3, and cleaved PARP), and an in situ TUNEL assay. The body weight and serum chemistry of treated mice were also assessed. In vitro, the effects of KSY were evaluated using MTT assay, BrdU incorporation assay and cell growth curve. RESULTS: In vivo, KSY suppressed bladder or lung cancer growth but did not promote the production of cytokines nor increase the accumulation of TILs. The expression of p53 and p21 in KSY-treated mice were increased. The numbers of apoptotic tumor cells and the expression of apoptosis marker proteins (Caspase 3 and cleaved PARP) were not significantly elevated after KSY treatment. In vitro, the viability and proliferation of tumor cells, but not normal cells, were suppressed by KSY treatment. No significant toxicity was found in KSY-treated mice. CONCLUSIONS: KSY suppressed the tumor growth in vivo and in vitro, which resulted from its cytostatic effects on cancer cells, rather than the induction of anti-cancer immunity. Under these experimental conditions, no apparent toxicity was observed.

Characteristics of early short-term traditional Chinese medicine in breast cancer patients: A population-based cohort study.

BACKGROUND: Traditional Chinese medicine (TCM) is frequently utilized as a complementary therapy for breast cancer patients. TCM primarily involves the use of Chinese herbal products (CHPs), which consist of single or multiherb formulas with diverse therapeutic effects documented in medical classics. The study aims to investigate the association between medication possession ratios to CHPs within 2-year post breast cancer diagnosis and 5-year survival, to explore the potential beneficial class effect of TCM. METHODS: This retrospective population-based cohort study included newly diagnosed breast cancer patients between 2003 and 2006, identified from the National Health Insurance Research Database of Taiwan. Logistic regression and Cox proportional hazards analysis were utilized to assess the likelihood of medication possession ratios (MPRs) for CHPs and to examine the association of variables with 5-year survival. RESULTS: A total of 3472 patients with breast cancer were included. Patients who had MPR of 1% to 9% and 10% to 19% for CHPs within 2 years after breast cancer diagnosis exhibited better 5-year survival rates compared with those who did not use CHPs (adjusted hazard ratio [aHR] 0.69, 95% confidence interval [CI] 0.55-0.86, p = 0.001; aHR 0.50, 95% CI 0.28-0.88, p = 0.016). Furthermore, the use of TCM formulations specifically targeting insomnia, such as Tian-wang-bu-xin-dan and Suan-zao-ren-tang, demonstrated a significantly positive association with survival (aHR 0.71, 95% CI 0.52-0.98, p = 0.035) among patients who were short-term users of CHPs (MPR of 1% to 19%). CONCLUSION: Short-term use of TCM (ie, MPR to CHPs 1~19%) within 2-year post breast cancer diagnosis present positive association with survival outcome. Tian-wang-bu-xin-dan and Suan-zao-ren-tang may have benefits to 5-year survival, but their causality still need further investigation.

Cinnamaldehyde inhibits the NLRP3 inflammasome by preserving mitochondrial integrity and augmenting autophagy in Shigella sonnei-infected macrophages.

BACKGROUND: Worldwide, more than 125 million people are infected with Shigella each year and develop shigellosis. In our previous study, we provided evidence that Shigella sonnei infection triggers activation of the NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome in macrophages. NLRP3 inflammasome is responsible for regulating the release of the proinflammatory cytokines interleukin (IL)-1ß and IL-18 through the protease caspase-1. Researchers and biotech companies have shown great interest in developing inhibitors of the NLRP3 inflammasome, recognizing it as a promising therapeutic target for several diseases. The leaves of Cinnamomum osmophloeum kaneh, an indigenous tree species in Taiwan, are rich in cinnamaldehyde (CA), a compound present in significant amounts. Our aim is to investigate how CA affects the activation of the NLRP3 inflammasome in S. sonnei-infected macrophages. METHODS: Macrophages were infected with S. sonnei, with or without CA. ELISA and Western blotting were employed to detect protein expression or phosphorylation levels. Flow cytometry was utilized to assess H2O2 production and mitochondrial damage. Fluorescent microscopy was used to detect cathepsin B activity and mitochondrial ROS production. Additionally, colony-forming units were employed to measure macrophage phagocytosis and bactericidal activity. RESULTS: CA inhibited the NLRP3 inflammasome in S. sonnei-infected macrophages by suppressing caspase-1 activation and reducing IL-1ß and IL-18 expression. CA also inhibited pyroptosis by decreasing caspase-11 and Gasdermin D activation. Mechanistically, CA reduced lysosomal damage and enhanced autophagy, while leaving mitochondrial damage, mitogen-activated protein kinase phosphorylation, and NF-κB activation unaffected. Furthermore, CA significantly boosted phagocytosis and the bactericidal activity of macrophages against S. sonnei, while reducing secretion of IL-6 and tumour necrosis factor following infection. CONCLUSION: CA shows promise as a nutraceutical for mitigating S. sonnei infection by diminishing inflammation and enhancing phagocytosis and the bactericidal activity of macrophages against S. sonnei.

The anti-COVID-19 drug nirmatrelvir crosses the blood‒brain barrier and exhibits herb-drug pharmacokinetic interactions with Scutellaria baicalensis formulations.

Aim of the study: Our hypothesis is that nirmatrelvir can penetrate the blood‒brain barrier and reach effective concentrations in the brain. Furthermore, herbal formulations can help maintain nirmatrelvir levels in the body, suggesting potential interactions between these medications. Materials and methods: To investigate this hypothesis, an animal model combining multisite microdialysis, ultrahigh-performance liquid chromatography and tandem mass spectrometry (UHPLC-MS/MS) methods was developed to monitor nirmatrelvir levels in the blood and brain of rats. Results: The pharmacokinetic results showed that the area under the curve (AUC) of nirmatrelvir in the blood and brain was 798.3 ± 58.56 and 187.2 ± 23.46 min µg/mL, respectively, after the administration of nirmatrelvir alone (15 mg/kg, iv). When the Scutellaria baicalensis formulations were administered for five consecutive days prior to drug administration, the AUC of nirmatrelvir in the blood increased. Conclusions: These results provide constructive preclinical information that the concentrations of nirmatrelvir in the blood and brain were greater than the effective concentration (EC90) for more than 6 h, and the Scutellaria baicalensis formulations had synergistic pharmacokinetic effects by increasing the concentration of nirmatrelvir in the blood.

Honokiol Exhibits Anti-NLRP3 Inflammasome and Antimicrobial Properties in Neisseria gonorrhoeae-Infected Macrophages.

Purpose: The NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome, crucial in infectious and inflammatory diseases by regulating IL-1ß, presents a target for disease management. Neisseria gonorrhoeae causes gonorrhea in over 87 million people annually, with previous research revealing NLRP3 inflammasome activation in infected macrophages. No natural products have been reported to counteract this activation. Exploring honokiol, a phenolic compound from Chinese herbal medicine, we investigated its impact on NLRP3 inflammasome activation in N. gonorrhoeae-infected macrophages. Methods: Honokiol's impact on the protein expression of pro-inflammatory mediators was analyzed using ELISA and Western blotting. The generation of intracellular H2O2 and mitochondrial reactive oxygen species (ROS) was detected through specific fluorescent probes (CM-H2DCFDA and MitoSOX, respectively) and analyzed by flow cytometry. Mitochondrial membrane integrity was assessed using specific fluorescent probes (MitoTracker and DiOC2(3)) and analyzed by flow cytometry. Additionally, the effect of honokiol on the viability of N. gonorrhoeae was examined through an in vitro colony-forming units assay. Results: Honokiol effectively inhibits caspase-1, caspase-11 and GSDMD activation and reduces the extracellular release of IL-1ß, NLRP3, and apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) in N. gonorrhoeae-infected macrophages. Detailed investigations have demonstrated that honokiol lowers the production of H2O2 and the phosphorylation of ERK1/2 in N. gonorrhoeae-infected macrophages. Importantly, the phosphorylation of JNK1/2 and p38 and the activation of NF-κB remain unaffected. Moreover, honokiol reduces the N. gonorrhoeae-mediated generation of reactive oxygen species within the mitochondria, preserving their integrity. Additionally, honokiol suppresses the expression of the pro-inflammatory mediator IL-6 and inducible nitric oxide synthase induced by N. gonorrhoeae independently of NLRP3. Impressively, honokiol exhibits in vitro anti-gonococcal activity against N. gonorrhoeae. Conclusion: Honokiol inhibits the NLRP3 inflammasome in N. gonorrhoeae-infected macrophages and holds great promise for further development as an active ingredient in the prevention and treatment of symptoms associated with gonorrhea.

The impact of chemotherapy in cancer patients: reflection on traditional Chinese symptom complex, cancer-related fatigue, and quality of life.

Traditional Chinese medicine is a trend in cancer holistic care. We found that patients undergoing chemotherapy had more traditional Chinese medicine symptom complexes with qi and blood deficiency and led poor quality of life and experienced fatigue. The traditional Chinese medicine theory based on qi and blood supply in cancer care deserves further research.

The intention of utilization and experience toward traditional Chinese medicine among breast cancer patients in the early and late stages: a qualitative study.

BACKGROUND: In Taiwan, breast cancer patients usually take conventional medicine and traditional Chinese medicine simultaneously. The utilization of traditional Chinese medicine among breast cancer patients at various stages has not been examined. This study aims to compare the intention of utilization and experience toward traditional Chinese medicine among early- and late-stage breast cancer patients. METHOD: This qualitative research collected data from breast cancer patients through focus groups interview by convenience sampling. Conducted in 2 branches of Taipei City Hospital, a public hospital managed by the Taipei City government. Breast cancer patients > 20 years old and had used TCM for breast cancer therapy for at least 3 months were included in the interview. A semi-structured interview guide was adopted in each focus group interview. In the following data analysis, stages I and II were considered early-stage, and stages III and IV were late-stage. For analyzing the data and reporting the results, we used qualitative content analysis as the approach for data analysis, assisted by NVivo 12. Categories and subcategories were identified through content analysis. RESULTS: Twelve and seven early- and late-stage breast cancer patients were included in this study, respectively. The side effects were the main intention of utilizing traditional Chinese medicine. Improving side effects and constitution was the main benefit for patients in both stages. Additionally, early-stage breast cancer patients used traditional Chinese medicine to prevent recurrence or metastasis. Late-stage breast cancer patients responded more frequently to the use of traditional Chinese medicine due to the side effects of western medicine. However, some of their symptoms were not fully relieved. CONCLUSIONS: Breast cancer staging may influence the intention and utilization of traditional Chinese medicine. Health policymakers should consider the results of this research and the evidence-based illustrations to establish guidelines for integrating traditional Chinese medicine among various stages of breast cancer to improve the outcome and quality of care for cancer patients.
