Thoughts of treatment of tumor diseases based on toxic pathogen theory / 中国中药杂志

The toxic pathogen theory, an important part of the theories of traditional Chinese medicine(TCM), began in the Qin and Han dynasties, formed in the Jin, Sui, Tang, and Song dynasties, developed rapidly in the Ming and Qing dynasties, and conti-nued to develop in contemporary times based on the achievements of its predecessors. The continuous exploration, practice, and inheri-tance of many medical practitioners over the generations have facilitated the enrichment of its connotation. The toxic pathogen is violent, fierce, dangerous, prolonged, rapid in transmission, easy to hurt the internal organs, hidden, and latent, with many changes, and it is closely related to the development of tumor diseases. TCM has a history of thousands of years in the prevention and treatment of tumor diseases. It is gradually realized that the etiology of tumor is mainly attributed to the deficiency of healthy Qi and excess of to-xic pathogen, and the struggle between healthy Qi and toxic pathogen runs through the whole course of tumor, with the deficiency of healthy Qi as the prerequisite and the invasion of toxic pathogen as the root of the occurrence. The toxic pathogen has a strong carcinogenic effect and is involved in the whole process of tumor development, which is closely related to the malignant behaviors of tumors, including proliferation, invasion, and metastasis. This study discussed the historical origin and modern interpretation of the toxic pathogen theory in the prevention and treatment of tumors, with aims of sorting out the theoretical system based on the toxic pathogen theory in the treatment of tumor diseases, and illustrating the importance of the toxic pathogen theory in the treatment of tumors in the context of modern research on pharmacological mechanisms and the development and marketing of relevant anti-tumor Chinese medicinal preparations.

A systematic review of pharmacological activities, toxicological mechanisms and pharmacokinetic studies on Aconitum alkaloids / 中国天然药物

The tubers and roots of Aconitum (Ranunculaceae) are widely used as heart medicine or analgesic agents for the treatment of coronary heart disease, chronic heart failure, rheumatoid arthritis and neuropathic pain since ancient times. As a type of natural products mainly extracted from Aconitum plants, Aconitum alkaloids have complex chemical structures and exert remarkable biological activity, which are mainly responsible for significant effects of Aconitum plants. The present review is to summarize the progress of the pharmacological, toxicological, and pharmacokinetic studies of Aconitum alkaloids, so as to provide evidence for better clinical application. Research data concerning pharmacological, toxicological and pharmacokinetic studies of Aconitum alkaloids were collected from different scientific databases (PubMed, CNKI, Google Scholar, Baidu Scholar, and Web of Science) using the phrase Aconitum alkaloids, as well as generic synonyms. Aconitum alkaloids are both bioactive compounds and toxic ingredients in Aconitum plants. They produce a wide range of pharmacological activities, including protecting the cardiovascular system, nervous system, and immune system and anti-cancer effects. Notably, Aconitum alkaloids also exert strong cardiac toxicity, neurotoxicity and liver toxicity, which are supported by clinical studies. Finally, pharmacokinetic studies indicated that cytochrome P450 proteins (CYPs) and efflux transporters (ETs) are closely related to the low bioavailability of Aconitum alkaloids and play an important role in their metabolism and detoxification in vivo.

Anticancer Activity of Tubulosine through Suppression of Interleukin-6-Induced Janus Kinase 2/Signal Transducer and Activation of Transcription 3 Signaling / 한국유방암학회지

PURPOSE: The chemical structure of tubulosine has been known since the mid-1960s. However, little is known about its biological and pharmacological functions. The aim of this study was to investigate the novel functions of tubulosine in cancer treatment, specifically in breast cancer. METHODS: An Unpaired (Upd)-induced Drosophila cell line and interleukin (IL)-6-stimulated human breast cancer cell lines were used to investigate the biological and pharmacological activities of tubulosine in vitro. To investigate the activities of tubulosine, we performed molecular and cellular experiments such as Western blot and reverse transcription polymerase chain reaction analyses, immunoprecipitation and terminal deoxynucleotidyl transferase dUTP nick end labeling assays, and immunofluorescence staining using breast cancer cell lines. RESULTS: Tubulosine exhibited anticancer activity in IL-6-stimulated human breast cancer cells. Moreover, tubulosine reduced the tyrosine phosphorylation level and transcriptional activity of signal transducer and activator of transcription (STAT) protein at 92E in Upd-induced Drosophila cells. Additionally, tubulosine suppressed IL-6-induced Janus kinase 2 (JAK2)/STAT3 signaling, resulting in decreased viability and induction of apoptotic cell death in breast cancer cells. Interestingly, inhibition of IL-6-induced JAK2/STAT3 signaling by tubulosine was associated with the blocking of IL-6 receptor (IL-6R) and glycoprotein 130 (gp130) binding. CONCLUSION: Tubulosine exhibits anticancer activity through functional inhibition of IL-6-induced JAK2/STAT3 signaling by targeting IL-6Rα/gp130 binding in breast cancer cells. These findings suggest that tubulosine may hold promise for the treatment of inflammation-associated cancers, including breast cancer.

Analysis of the clinical treatment and the influence of compliance on amblyopia / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To explore the treatment methods and curative effect of amblyopia in children, and to analyze the effect of compliance on the treatment process.METHODS:The children with amblyopia treatment since January 1st 2010 in General Hospital of Jinan Military Area, were selected and completed follow-up for a total of 129 eyes of 78 patients, including 53 eyes of male in 31 cases and 76 eyes of female in 47 cases, the initial age of 3 to 12 years, the treatment were performed with accurate optometry, reasonable glasses and appropriate to cover the dominant eye based comprehensive therapy and compliance training of the parents and children.The treatment time was 12-36mo, followed up for 3a.The final therapeutic effect was observed and the difference of the stage curative effect between the children with different grade of compliance (good, moderate and poor grade) was compared.RESULTS:In the treatment of 36mo, 106 eyes were cured, 21 eyes were essentially recovered and the total cure rate was 98.4%, which was improved in 2 eyes (1.6%) and was ineffective in 0 eyes (0%);the total effective rate were 100%.The total cure rate was 69% in the treatment of 6mo and there was a significant difference in the cure rate among children with different compliance (overall comparison P<0.001, each comparison P<0.017).In the treatment of 12mo, the total cure rate was 89.1% and the cure rate were significantly different between children with the moderate compliance and the children with good compliance (P<0.05).CONCLUSION:Comprehensive treatment of children with amblyopia can achieve an ideal clinical efficacy.Compliance is an important factor influencing the treatment effect and the treatment process.The parents and children`s compliance training can shorten the course of treatment and improve the curative effect.

Interparental conflict and mental health in children and adolescents: the mediating effect of self-concept / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To examine the mediating effect of self-concept between interparental conflict and mental health in children and adolescents.</p><p><b>METHODS</b>A total of 689 students (10-18 years) were surveyed using the convenient sampling method, and their mental health, self-concept, and interparental conflict were examined by the general status questionnaire, Strengths and Difficulties Questionnaire, Self-Description Questionnaire, and Children's Perception of Interparental Conflict Scale. Structural equation modeling (SEM) and simultaneous analysis of several groups were used to construct the mediator model and analyze the data, respectively. The Bootstrap method was used to assess the significance of the mediating effects.</p><p><b>RESULTS</b>Interparental conflict was positively correlated with mental health of children and adolescents (P<0.05), but was negatively correlated with self-concept (P<0.01). Self-concept was negatively correlated with mental health (P<0.01). Self-concept had a partial (60%) mediating effect between interparental conflict and mental health. Academic stage, but not gender, had a regulatory role on interparental conflict, mental health, and self-concept.</p><p><b>CONCLUSIONS</b>Self-concept plays an important role between interparental conflict and mental health. It is necessary to improve self-concept level in children and adolescents exposed to interparental conflict.</p>
