Alternative therapy for acute appendicitis with appendicolith using traditional Chinese medicine: A case report.

INTRODUCTION: Treating older patients with acute appendicitis with multiple underlying diseases is a challenging situation in the clinical setting. Throughout the history of East Asian medicine, many texts have noted the use of herbal decoctions to successfully treat symptoms associated with appendicitis, thereby providing an alternative management strategy for treating frail patients with acute appendicitis. CASE PRESENTATION: This report presents the case of a 93-year-old male diagnosed with acute appendicitis with appendicolith who was unsuitable for surgical intervention due to poor lung condition and prolonged prothrombin time caused by Apixaban. By receiving complementary therapy consisting of traditional Chinese medicine (TCM) and antibiotics, he recovered successfully. DISCUSSION: In the early stage of acute appendicitis, infection control and gastrointestinal mobility are the most important factors to consider. Scientific research has demonstrated that many herbs used in TCM formulas possess anti-inflammatory, anti-oxidative and immune attenuation effects. For many patients who are unsuitable for surgical intervention due to unfavorable conditions, such as the prolonged prothrombin time presented in this case, complementary treatment with TCM offers adjuvant therapeutical effects associated with infection control, and improvement of the gastrointestinal environment and function of elderly patients.

TCM as adjunctive therapy improves risks of respiratory hospitalizations in persons with type 2 diabetes: A retrospective cohort study.

Patients with type 2 diabetes are at a higher risk of chronic obstructive pulmonary disease (COPD) and asthma than the general population. In addition, emerging evidence suggests that traditional Chinese medicine (TCM) might be beneficial for patients with type 2 diabetes. We investigated whether TCM use was associated with a reduced risk of respiratory hospitalizations in patients with type 2 diabetes. Conducting a retrospective cohort study, we used data retrieved from the NDCMP database. Among 56,035 patients, 5226 were classified as TCM users; 50,809 were classified as TCM nonusers. Both groups were analyzed until the end of 2011 to examine the incidence of respiratory hospitalizations by using a Cox proportional hazards model to evaluate effects of TCM use on respiratory hospitalizations. During the 6-year study follow-up period, the incidence density rates of COPD- and asthma-related hospitalization were estimated to be 13.03 and 4.47 per 10,000 patient-years for TCM nonusers and 10.08 and 3.28 per 10,000 patient-years for TCM users, respectively. The HR of COPD-related hospitalization in TCM users was 0.88 (95% CI = 0.79-0.99); and the HR of asthma-related hospitalization in TCM users was 0.81 (95% CI = 0.66-1.00). Stratified analyses revealed that effects of TCM use were stronger among individuals who had diabetes for <3 years. As a part of Integrative Medicine, our study results demonstrate that TCM use was associated with a significant reduced risk of respiratory hospitalizations, especially in patients with diabetes for <3 years.

Neuroprotective Effects of Alpinia oxyphylla Miq against Mitochondria-Related Apoptosis by the Interactions between Upregulated p38 MAPK Signaling and Downregulated JNK Signaling in the Subacute Phase of Cerebral Ischemia-Reperfusion in Rats.

Apoptosis in the penumbra region is the major cell death mechanism occurring during ischemia-reperfusion injury's early phase. Here, we evaluated how the Alpinia oxyphylla Miq (AOM) affects mitochondria-related apoptosis 3 days after transient middle cerebral artery occlusion (MCAo) and examined the mechanisms underlying the regulation of MAPK-mediated mitochondria-related apoptotic signaling in the peri-infarct cortex in rats. The rats were administered the AOM extract intraperitoneally at doses of 0.2[Formula: see text]g/kg (AOM-0.2[Formula: see text]g), 0.4[Formula: see text]g/kg (AOM-0.4[Formula: see text]g), or 0.8[Formula: see text]g/kg (AOM-0.8[Formula: see text]g) at MCAo initiation. The AOM-0.4[Formula: see text]g and AOM-0.8[Formula: see text]g significantly ameliorated apoptotic cell death and considerably downregulated cytochrome c (cyto c) and cleaved caspase-3 immunoreactivity 3 days after reperfusion. Simultaneously, they significantly downregulated cytosolic p-JNK/JNK, cathepsin B/actin, cyto c/actin, Smac/DIABLO/actin, cleaved caspase-3/actin, and AIF/actin and mitochondrial p53/HSP60 and Bax/HSP60 fractions but upregulated cytosolic p-p38 MAPK/p38 MAPK, p-p90RSK/actin, p-Bad/Bad, p-CREB/actin, and XIAP/actin and cytosolic and mitochondrial Bcl-2/Bax and Bcl-xL/Bax fractions in the peri-infarct cortex. Pretreatment with SB203580 - a p38 MAPK inhibitor - completely abrogated the effects of AOM-0.8[Formula: see text]g on the aforementioned protein expression, whereas treatment with SP600125 - a JNK inhibitor - exerted protective effects similar to those of AOM-0.8[Formula: see text]g. Treatment with 0.4 or 0.8[Formula: see text]g/kg AOM has neuroprotective effects against mitochondria-related apoptosis by suppressing cyto c, Smac/DIABLO, and AIF release from the mitochondria to cytosol. The anti-mitochondria related apoptotic effects of the AOM extract are attributable to the interactions between upregulated p38 MAPK/p90RSK-mediated p-Bad and CREB signaling and downregulated JNK/cathepsin B-mediated Bax and p53 signaling in the peri-infarct cortex 3 days after transient MCAo.

Targeting glycolysis in Th2 cells by pterostilbene attenuates clinical severities in an asthmatic mouse model and IL-4 production in peripheral blood from asthmatic patients.

Asthma, a major non-communicable disease, affects both adults and children and is associated with high morbidity compared with other chronic diseases. The glycolysis-associated activation of type 2 helper T (Th2) cells is the critical immunopathological mechanism involved in asthma deterioration. Long-term use of steroids as a medical treatment for asthma induces side effects and resistance. Pterostilbene (PS), a stilbenoid compound found in blueberry and vines, exhibits antihyperglycemic and anti-inflammatory properties. Thus, we hypothesized that the modulation of T cell immunity by PS may be an applicable intervention to treat asthma. Airway hyperresponsiveness, interleukin (IL)-4 and IL-13 levels, IgE, IgG, pulmonary infiltrated monocytes and eosinophils, and mucosubstances were measured in house dust mite (HDM)-induced asthmatic mice under PS treatment. Bioenergetic metabolism, PI3K-mTOR signalling, GATA3 expression and histone acetylation in PS-treated Th2 cells were investigated. PS improved HDM-induced pulmonary allergic airway inflammation by inhibiting Th2 cell and eosinophil accumulation in HDM asthmatic mice both in the preventive and therapeutic models. Targeting glycolysis resulted in IL-4 inhibition via the downregulation of mTOR, GATA3 and histone acetylation in PS-treated Th2 cells. Glucose supplementation reversed the inhibitory effect of PS on Th2 cells in vitro. Adoptive transfer with glucose-treated Th2 cells enhanced Th2 activation and eosinophilic accumulation in PS-treated asthmatic mice. Furthermore, PS significantly inhibited IL-4 production of CD4+ T cells from the peripheral blood mononuclear cells of patients with asthma. PS attenuates HDM-induced asthma via the inhibition of the Glut1/mTOR/GATA3 axis in Th2 cells, which supports the potential pharmaceutical application of PS treatment for asthma.

Synergistic cardiac pathological hypertrophy induced by high-salt diet in IGF-IIRα cardiac-specific transgenic rats.

Stress-induced cardiac hypertrophy leads to heart failure. Our previous studies demonstrate that insulin-like growth factor-II receptor (IGF-IIR) signaling is pivotal to hypertrophy regulation. In this study, we show a novel IGF-IIR alternative spliced transcript, IGF-IIRα (150 kDa) play a key role in high-salt induced hypertrophy mechanisms. Cardiac overexpression of IGF-IIRα and high-salt diet influenced cardiac dysfunction by increasing pathophysiological changes with up-regulation of hypertrophy markers, atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). We found that, cardiac hypertrophy under high-salt conditions were amplified in the presence of IGF-IIRα overexpression. Importantly, high-salt induced angiotensin II type I receptor (AT1R) up regulation mediated IGF-IIR expressions via upstream mitogen activated protein kinase (MAPK)/silent mating type information regulation 2 homolog 1 (SIRT1)/heat shock factor 1 (HSF1) pathway. Further, G-coupled receptors (Gαq) activated calcineurin/nuclear factor of activated T-cells, cytoplasmic 3 (NFATc3)/protein kinase C (PKC) signaling was significantly up regulated under high-salt conditions. All these effects were observed to be dramatically over-regulated in IGF-IIRα transgenic rats fed with a high-salt diet. Altogether, from the findings, we demonstrate that IGF-IIRα plays a crucial role during high-salt conditions leading to synergistic cardiac hypertrophy.

Overexpression of IGF-IIRα regulates cardiac remodeling and aggravates high salt induced apoptosis and fibrosis in transgenic rats.

IGF-IIR activation regulates cardiac remodeling leading to apoptosis. Here, we identified the novel IGF-IIRα (150 KDa), a truncated IGF-IIR transcript enhances cardiac apoptosis under high-salt uptake in transgenic rat model. Echocardiographic analysis revealed decline in ejection fraction and fractional shortening percentage in IGF-IIRα (TG) rats. We found that IGF-IIRα TG rats developed severe apoptosis and fibrosis as identified through TUNEL assay and Masson's trichrome staining. Importantly, the heart functioning, apoptosis, and fibrosis were significantly affected under high-salt conditions in IGF-IIRα (TG) rats. Significant upregulation of apoptosis was evident from decreased Bcl-2, p-AKT, and p-PI3K expressions with concomitant increase in Bad, cytochrome C, cleaved caspase 3 levels. We found that, IGF-IIRα highly induced tissue fibrosis through collagen accumulation (col I, col III) and up regulated various fibrotic markers such as tPA, uPA, TGF-ß, and vimentin expressions. The observed upregulation of fibrosis were significantly regulated under high-salt conditions and their over regulation under IGF-IIRα over expressions shows the key role of IGF-IIRα in promoting high-salt induced fibrosis. During IGF-IIRα over expression induced cardiotoxicity, under high salt condition, and it destroys the interaction between CHIP and HSF1, which promotes the degradation of HSF1 and results in upregulation of IGF-IIR/IGF-IIRα expressions. Altogether, the study unveils novel IGF-IIRα in the regulation of cardiac apoptosis and fibrosis under high-salt diet.

A Controlled Trial of Sheng-Yu-Tang for Post-Hematopoietic Stem Cell Transplantation Leukemia Patients: A Proposed Protocol and Insights From a Preliminary Pilot Study.

INTRODUCTION: Hematopoietic stem cell transplantation has become a well-established treatment for hematologic disorders including acute leukemia. However, long-term survival rates following this procedure are still extremely low, due to posttransplantation relapse, infections, and graft-versus-host disease. We propose that adjunctive Chinese herbal medicine may benefit posttransplantation patients. In preparation for a randomized clinical trial, we conducted a pilot trial. Methods and Analysis: Between September 2015 and June 2017, 18 patients were consecutively enrolled at China Medical University Hospital and followed for up to 1 year. Fresh blood samples were obtained on a monthly basis, and immune reconstitution was analyzed. In addition to the standard-care treatment administered by their oncologist, a number of patients also received a Chinese herbal formula (Sheng-Yu-Tang) for up to 6 months. Results were used to improve on study protocol and estimate required sample size for a future randomized trial. Ethics and Dissemination: Study protocol was approved by the institutional review board of China Medical University Hospital (DMR-105-005), and all participants provided informed consent.

Short-term hypoxia upregulated Mas receptor expression to repress the AT1 R signaling pathway and attenuate Ang II-induced cardiomyocyte apoptosis.

Hypertension-stimulated cardiac hypertrophy and apoptosis play critical roles in the progression of heart failure. Our previous study suggested that hypertensive angiotensin II (Ang II) enhanced insulin-like growth factor receptor II (IGF-IIR) expression and cardiomyocyte apoptosis, which are involved JNK activation, sirtuin1 (SIRT1) degradation, and heat-shock transcription factor 1 (HSF1) acetylation. Moreover, previous studies have implied that short-term hypoxia (STH) might exert cardioprotective effects. However, the effects of STH on Ang II-induced cardiomyocyte apoptosis remain unknown. In this study, we found that STH reduced myocardial apoptosis caused by Ang II via upregulation of the Mas receptor (MasR) to inhibit the AT1 R signaling pathway. STH activates MasR to counteract the Ang II pro-apoptotic signaling cascade by inhibiting IGF-IIR expression via downregulation of JNK activation and reduction of SIRT1 degradation. Hence, HSF could remain deacetylated, and repress IGF-IIR expression. These effects decrease the activation of downstream pro-apoptotic and hypertrophic cascades and protect cardiomyocytes from Ang II-induced injury. In addition, we also found that silencing MasR expression enhanced Ang II-induced cardiac hypertrophy and the apoptosis signaling pathway. These findings suggest a critical role for MasR in cardiomyocyte survival. Altogether, our findings indicate that STH protects cardiomyocytes from Ang II-stimulated apoptosis. The protective effects of STH are associated with the upregulation of MasR to inhibit AT1 R signaling. STH could be a potential therapeutic strategy for cardiac diseases in hypertensive patients.

Cardiac apoptosis induced under high glucose condition involves activation of IGF2R signaling in H9c2 cardiomyoblasts and streptozotocin-induced diabetic rat hearts.

The insulin-like growth factor type 2 receptor (IGF2R) overexpression has been implicated in heart disease progression. Unregulated IGF2R signaling triggers cardiac hypertrophy, apoptosis, and cardiomyopathies. The present study investigated the role of IGF2R in cardiomyocyte apoptosis under high glucose (HG) levels and in streptozotocin (STZ) induced diabetic rat hearts. We found that IGF2 and IGF2R protein expression were highly upregulated under high glucose condition in H9c2 cells as well as in STZ induced diabetic rat hearts. Using immunoblotting and TUNEL assay, we found that elevated glucose condition induced IGF2R expression leads to activation of Gαq mediated calcineurin-dependent signaling pathway, which further leads to downstream activation and expression of cardiac hypertrophy related proteins, ANP and BNP. Further, we found that glucose-induced IGF2R expression downregulated survival protein p-Akt, p-Bad (Ser 155) and enhanced the expression of apoptosis-inducing proteins cytochrome c and cleaved Caspase-3. Our results suggested that hyperglycemic condition leads to cellular cardiomyocyte apoptosis both in vitro and in vivo models, via abnormally increased activation of the IGF2R signaling pathway.

Use of Complementary Traditional Chinese Medicines by Adult Cancer Patients in Taiwan: A Nationwide Population-Based Study.

BACKGROUND: Many patients with cancer seek complementary and alternative medicine treatments. We investigated the use of traditional Chinese medicine (TCM) by adult cancer patients in Taiwan. METHODS: We reviewed the Registry for Catastrophic Illness Patients Database of Taiwan, and included all adult patients diagnosed cancer, based on the International Classification of Diseases (ninth revision), from 2001 to 2009 and followed until 2011. This database allowed categorization of patients as TCM users (n = 74 620) or non-TCM users (n = 508 179). All demographic and clinical claims data were analyzed. RESULTS: Compared with non-TCM users, TCM users were younger and more likely to be female, white-collar workers, and reside in highly urbanized areas. The average interval between cancer diagnosis and TCM consultation was 15.3 months. The most common cancer type was breast cancer in TCM users (19.4%), and intrahepatic bile duct cancer in non-TCM users (13.6%). The major condition for which TCM users visited clinics were endocrine, nutritional and metabolic diseases, and immunity disorders (23.2%). A total of 33.1% of TCM users visited TCM clinics more than 9 times per year and their time from diagnosis to first TCM consultation was 5.14 months. The most common TCM treatment was Chinese herbal medicine. The common diseases for which cancer patients sought TCM treatment were insomnia, malaise and fatigue, dizziness and headache, gastrointestinal disorders, myalgia and fasciitis, anxiety, and depression. Overall, TCM users had a lower adjusted hazard ratio (aHR) for mortality (aHR = 0.69, 95% CI = 0.68-0.70) after adjustment for age, sex, urbanization of residence, occupation, annual medical center visits, and annual non-medical center visits. CONCLUSIONS: This study provides an overview of TCM usage among adult cancer patients in Taiwan. TCM use varied among patients with different types of cancer. Physicians caring for cancer patients should pay more attention to their patients' use of complementary TCM.

Complementary Chinese Herbal Medicine Therapy Improves Survival of Patients With Pancreatic Cancer in Taiwan: A Nationwide Population-Based Cohort Study.

BACKGROUND: Pancreatic cancer is a difficult-to-treat cancer with a late presentation and poor prognosis. Some patients seek traditional Chinese medicine (TCM) consultation. We aimed to investigate the benefits of complementary Chinese herbal medicine (CHM) among patients with pancreatic cancer in Taiwan. METHODS: We included all patients with pancreatic cancer who were registered in the Taiwanese Registry for Catastrophic Illness Patients Database between 1997 and 2010. We used 1:1 frequency matching by age, sex, the initial diagnostic year of pancreatic cancer, and index year to enroll 386 CHM users and 386 non-CHM users. A Cox regression model was used to compare the hazard ratios (HRs) of the risk of mortality. The Kaplan-Meier curve was used to compare the difference in survival time. RESULTS: According to the Cox hazard ratio model mutually adjusted for CHM use, age, sex, urbanization level, comorbidity, and treatments, we found that CHM users had a lower hazard ratio of mortality risk (adjusted HR = 0.67, 95% CI = 0.56-0.79). Those who received CHM therapy for more than 90 days had significantly lower hazard ratios of mortality risk than non-CHM users (90- to 180-day group: adjusted HR = 0.56, 95% CI = 0.42-0.75; >180-day group: HR = 0.33, 95% CI = 0.24-0.45). The survival probability was higher for patients in the CHM group. Bai-hua-she-she-cao (Herba Oldenlandiae; Hedyotis diffusa Spreng) and Xiang-sha-liu-jun-zi-tang (Costus and Chinese Amomum Combination) were the most commonly used single herb and Chinese herbal formula, respectively. CONCLUSIONS: Complementary Chinese herbal therapy might be associated with reduced mortality among patients with pancreatic cancer. Further prospective clinical trial is warranted.

Characteristics of traditional Chinese medicine usage in children with precocious puberty: A nationwide population-based study.

ETHNOPHARMACOLOGICAL RELEVANCE: Precocious puberty (PP) occurs in children with the early onset of pubertal development leading to physical and psychological problems. Current medical treatment is expensive and has its side effects. However, little is known about the utilization of traditional Chinese medicine (TCM) among patients with PP. To characterize the application of TCM among these patients, we conducted a nationwide population-based study. MATERIALS AND METHODS: We used the Taiwanese National Health Insurance Research Database (NHIRD), to perform a nationwide population-based study. The NHIRD has a derived dataset with the information for a randomly selected half of all insured children from 1997 to 2008 in Taiwan. We identified children <18 years of age with newly diagnosed sexual precocity (ICD-9 CM code: 259.1). The subjects were categorized based on the inclusion of TCM in their treatment plan. RESULTS: Overall, 3495 newly diagnosed subjects with sexual precocity were included. Among these children, 1.86% (N=65) had used TCM. There were significantly more subjects with no treatment, 87.32% (N=3052), than those with treatment of TCM, western medicine, or both. Most of the TCM users received Chinese herbal remedies (98.25%), and only 1.75% received acupuncture or manipulative therapies. Zhi-Bai-Di-Huang-Wan was the most frequently prescribed TCM formulation (23.73%), while Mai-Ya (Fructus Hordei Germinatus) was the most commonly prescribed single herb (10.87%). CONCLUSION: Our study identified the characteristics and prescription patterns of TCM for children with PP in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the efficacy and mechanism.

Complementary traditional Chinese medicine use in Children with cerebral palsy: a nationwide retrospective cohort study in Taiwan.

BACKGROUND: Complementary traditional Chinese medicine (TCM) has been used to treat patients with cerebral palsy (CP). However, large-scale surveys examining its use in the treatment of CP and associated disorders are lacking. METHODS: We enrolled 11,218 patients ≤ 18 years of age with CP in the Taiwanese National Health Insurance Research Database from 1995 to 2011. Patients were categorized as TCM users (n = 6,997; 62.37%) and non-TCM users (n = 4,221; 37.63%) based on the inclusion of TCM in their treatment plan. RESULTS: Children with higher proportions of complementary TCM use were male, younger, and lived in urbanized areas. Most TCM users (n = 5332, 76.2%) visited TCM outpatient departments more than 20 times per year. In both groups, the three most common reasons for clinical visits were problems of the nervous system, respiratory system, and digestive system. Acupuncture was commonly used in problems of injury, musculoskeletal system and connective tissue, and nervous system. Chinese herbal medicine was used to improve the primary symptoms of CP in patients, as well as its associated disorders. The incidence rate ratios in allergic rhinitis, dyspepsia, menstrual disorders, and musculoskeletal system and connective tissue diseases among TCM users were significantly higher than non-TCM users. Although patients receiving complementary TCM therapies had higher medical expenditure for utilizing outpatient clinical consultations, their medical costs for visiting ER and hospitalization were significantly lower than that of non-TCM user within one year of the diagnosis of CP. CONCLUSION: This study was a large-scale survey to characterize patterns of complementary TCM use among children with CP. The complementary use of TCM in children with CP was considerably high. Future clinical trials and basic researches can be developed based on the findings of this study.

Improved Survival With Integration of Chinese Herbal Medicine Therapy in Patients With Acute Myeloid Leukemia: A Nationwide Population-Based Cohort Study.

PURPOSE: Acute myeloid leukemia (AML) is the most deadly subtype of leukemia, and many patients with this disease seek other complementary therapies, one of which is Chinese medicine. We set out to provide reliable data regarding the benefit of Chinese herbal medicine (CHM) for AML patients, using mortality as the main outcome measure. We also characterized the herbal prescriptions of patients. METHODS: Using the Taiwanese National Health Insurance Research Database, we performed a nationwide population-based cohort study among AML patients from 1997 to 2010. The Cox regression model was used to adjust for comorbidities and other variables, and the hazard ratios (HRs) of CHM users and non-CHM users were compared. RESULTS: After 1:1 matching, 498 patients were included into the study. The HR of the CHM group was 0.41 (95% CI = 0.26-0.65; P = .0001) compared with the non-CHM group. This decrease in HR was also shown to be dose dependent ( P < .001). The 3 single-herbs most commonly prescribed were Salvia miltiorrhiza (Dan Shen), Astragalus membranaceus (Huang Qi), and Spatholobus suberectus (Ji Xue Teng). The 3 mutli-herb products most commonly prescribed were Jia Wei Xiao Yao San, Gui Pi Tang, and Qi Ju Di Huang Wan. CONCLUSION: Prospective controlled clinical data is still needed, however, this study provides real-world data regarding the benefit AML patients may have from CHM. This study suggests that all AML patients, regardless of age or other prognostic factors, may achieve longer survival times when receiving CHM in addition to standard therapy.

Post-hematopoietic stem cell transplantation in patients with hematologic disorders: Chinese herbal medicine for an unmet need.

While much progress has been made in the field of hematopoietic stem cell transplantation (HSCT), headway in the promotion of recovery following this procedure has been limited. Data regarding the potential of Chinese herbal medicine (CHM) for patients with hematologic disorders who received HSCT are gradually increasing; however, these data are mostly in Chinese. Therefore, we set out to summarize the existing data. We searched PubMed, the Cochrane Library and the China National Knowledge Infrastructure and retrieved 9 clinical studies related to this group of patients, in whom CHM was used as an intervention. Of the 9 papers, 6 were published by the same group of researchers. The focus of the reviewed studies was heterogeneous, and the objectives varied widely. With the exception of one randomized control trial, all of the studies were retrospective and observational; the median number of patients was 11.5, with the largest study containing 104 patients. CHM treatment was largely divided into two stages: (1) pre-HSCT, which was initiated as soon as conditioning chemotherapy was administered and aimed to counterbalance the adverse effects of these potent agents; (2) post-HSCT, which began immediately after transplantation and was intended to promote engraftment, control graft-versus-host disease and prolong survival. In addition, the 9 Chinese materia medica most commonly prescribed (appearing in four studies) were: Shengdihuang (Rehmannia glutinosa), Baizhu (Atractylodes macrocephala), Renshen (Panax ginseng), Dangshen (Codonopsis pilosula), Maimendong (Ophiopogon japonicus), Danggui (Angelica sinensis), Taizishen (Pseudostellaria heterophylla), Huangqi (Astragalus membranaceus) and Ejiao (Equus asinus).

In Silico Investigation of Traditional Chinese Medicine for Potential Lead Compounds as SPG7 Inhibitors against Coronary Artery Disease.

Coronary artery disease (CAD) is the most common cause of heart attack and the leading cause of mortality in the world. It is associated with mitochondrial dysfunction and increased level of reactive oxygen species production. According to the Ottawa Heart Genomics Study genome-wide association study, a recent research identified that Q688 spastic paraplegia 7 (SPG7) variant is associated with CAD as it bypasses the regulation of tyrosine phosphorylation of AFG3L2 and enhances the processing and maturation of SPG7 protein. This study aims to identify potential compounds isolated from Traditional Chinese Medicines (TCMs) as potential lead compounds for paraplegin (SPG7) inhibitors. For the crystallographic structure of paraplegin, the disordered disposition of key amino acids in the binding site was predicted using the PONDR-Fit protocol before virtual screening. The TCM compounds saussureamine C and 3-(2-carboxyphenyl)-4(3H)-quinazolinone, have potential binding affinities with stable H-bonds and hydrophobic contacts with key residues of paraplegin. A molecular dynamics simulation was performed to validate the stability of the interactions between each candidate and paraplegin under dynamic conditions. Hence, we propose these compounds as potential candidates as lead drug from the compounds isolated from TCM for further study in drug development process with paraplegin protein for coronary artery disease.

Integration of Chinese Herbal Medicine Therapy Improves Survival of Patients With Chronic Lymphocytic Leukemia: A Nationwide Population-Based Cohort Study.

Utilization of Chinese Medicine (CM) is not uncommon in patients with chronic lymphocytic leukemia (CLL). However, the current knowledge of the usage and efficacy of CM among CLL patients is limited. The aim of this study was to determine the impact of integrative Chinese Herbal Medicine (CHM) on the disease course of CLL and ascertain the herbal products most commonly prescribed to patients with CLL.A Taiwanese nationwide population-based study involving the use of Western medicine and CM services provided by the National Health Insurance (NHI) was conducted.An NHI Research Database-based cohort study was performed; the timeframe of the study was January 2000 to December 2010. The end of the follow-up period was defined as December 31, 2011.A total of 808 patients were diagnosed with CLL in Taiwan within the defined study period. After randomly matching for age and sex and excluding patients younger than 18 years of age, data from 616 patients were analyzed.The 2 study groups both received standard of care treatment. In addition, 1 group also received CHM. Patients who were registered as receiving other forms of CM, such as acupuncture, were excluded.Hazard ratios of mortality were used to determine the influence of CHM and the therapeutic potential of herbal products.In total, 616 CLL patients were included in the analyses. We found that the HR associated with the adjunctive use of CHM was less than half when compared to the non-CHM group (0.43, 95% CI 0.33-0.55, P < 0.0001) and that treatment-naive patients who used CHM had the lowest HR. We also established that this association between reduction in HR and CHM was dose-dependent, and the longer CHM users received prescriptions, the lower the HR (P < 0.001).We supplied data from a relatively large population that spanned a significant amount of time. Our data suggests that the treatment of CLL with adjunctive CHM may have a substantial positive impact on mortality, especially for treatment-naive patients. Further research is needed to confirm whether there is a direct causal relationship between CHM and the outcomes displayed.

Adjunctive Chinese Herbal Medicine therapy improves survival of patients with chronic myeloid leukemia: a nationwide population-based cohort study.

Despite good clinical results of current drugs, a good reason still exists to search for additional therapies for the management of Chronic Myeloid Leukemia (CML). Chinese Herbal Medicine (CHM) has thus far been overlooked by researchers and no data exists on the subject. We studied the impact of adjunctive CHM on the disease course of CML, using mortality as the major outcome measurement. We used the Taiwanese National Health Insurance Research Database to perform a nationwide population-based cohort study. Our study included CML patients diagnosed between 2000 and 2010. We matched groups according to age, sex, Charlson Comorbidity Index (CCI) score and use of imatinib, and compared the Hazard Ratios (HR) of CHM group and non-CHM users, as well as characterized trends of prescriptions used for treating CML. 1371 patients were diagnosed with CML in the years examined, of which 466 were included in to this study. We found that the HR of CHM group was significantly lower compared to non-CHM groups (0.32, 95% CI 0.22-0.48, P < 0.0001). We also established that this association between reduced HR was dose-dependent, and the longer CHM users received prescriptions, the lower the HR (P < 0.01). We also analyzed the most commonly used herbal products as well as the HR associated to their use, thus providing future research candidates. Our results supply a strong reason to assume that when administered by properly trained physicians, CHM may have a substantial positive impact on the management of CML.

Residue-based design of small molecule inhibitor for H1N1, H5N1 and H7N1 mutants.

Point mutations H274Y and N294S can lead to resistance of influenza virus strains to some drug molecules. Recently, a large number of experiments has focused on the many frameworks and catalytic residues thought to prevent the efficacy of anti-flu drugs. In the past, most research has considered the role of drugs in rigid proteins rather than in flexible proteins. In this study, we used molecular dynamics simulation (MD) combined with structure- and ligand-based drug design (SBDD and LBDD) methods to study dynamic interaction and protein dynamics correlation statistics between compounds and both the framework and catalytic residues in influenza virus N1 strains. Drug candidates were screened using the IC50 of the docking result predicted by support vector machine, multiple linear regression, and genetic function approximation (P < 0.001). As shown by MD, saussureamine C and diiodotyrosine have a protein dynamics correlation similar to that of sialic acid, and both can participate in hydrogen bond formation with loop, framework, and catalytic residues. Our in silico findings suggest that saussureamine C can inhibit H274Y and N294S mutants, and that diiodotyrosine can also inhibit N294S mutants. Therefore, the drugs saussureamine C and diiodotyrosine have the potential to produce inhibitory effects on wild-type influenza virus and some N1 mutants.

Prescription patterns of Chinese herbal products for patients with uterine fibroid in Taiwan: A nationwide population-based study.

ETHNOPHARMACOLOGICAL RELEVANCE: Uterine fibroid (myoma) is one of the most common diseases in women. Although there are several studies on the efficacy of Chinese herbs, there is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of uterine fibroid. This study aimed to investigate the utilization of Chinese herbal products for patients with uterine fibroid, prescribed by licensed TCM doctors in Taiwan. MATERIALS AND METHODS: A random sample comprised of one million individuals with newly diagnosed uterine fibroid between 2002 and 2010 from the Taiwanese National Health Insurance Research Database was analyzed. Demographic characteristics, TCM usage, the frequency as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with uterine fibroid, were analyzed. RESULTS: Overall, 35,786 newly diagnosed subjects with uterine fibroid were included. Majority of these patients (87.1%; n=31,161) had visited TCM clinics. Among them, 61.8% of their visits used Chinese herbal remedies. Patients less than 45 years of age tended to use TCM more frequently than elder patients. Gui-Zhi-Fu-Ling-Wan (Cinnamon Twig and Poria Pill) was the most frequently prescribed Chinese herbal formula, while San-Leng (Rhizoma Sparganii) was the most commonly prescribed single herb. CONCLUSIONS: Our study identified the characteristics and prescription patterns of TCM for patients with uterine fibroid in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the therapeutic effects and mechanisms.
