2.Development of relationship between intestinal commensal bacteria and intestinal epithelial barrier
International Journal of Pediatrics 2010;37(6):597-600
After birth,human intestinal tract mucosa is exposed to a large community of commensal and pathogenic bacteria. As a first line of defense,the intestinal epithelial barrier (IEB) kills the pathogen by signaling to the innate immune system, through pattern recognition receptors, while it produces protective respond towards the commensal bacteria. Intestinal epithelial cells play an important role in forming immune tolerance to the commensal bacteria and make intestinal homeostasis. Commensal bacteria can resist the pathogenic bacteria invasion. The signals of commensal are required for development of intestinal epithelial barrier and intestinal innate and adaptive immunity. It is essential for the host to have a balance between the commensal bacteria and intestinal tract,once the balance is broken, the intestinal inflammation disease will be caused. Thus ,this review will discuss the relationship between intestinal commensal bacteria and intestinal epithelial barrier in several aspects, such as the role of the commensal bacteria, the mechanism of producing commensal tolerance by IEB and the disease caused by imbalance between the commensal and IEB.
3.Integretion of pharmacokinetics and pharmacodynamics in antibacterial drug development and pharmacotherapy
Chinese Journal of Clinical Pharmacology and Therapeutics 2007;12(10):1099-1113
There is a pressing need for new antibacterial agents due to the development of drug-resistant pathogens. Unfortunately drug development is a difficult and complicated process. The traditional approach in searching for a right dose is quite empirical, both costly and time-consuming. To enhance the ability to predict the likelihood of success for lead compound selection, in vitro pharmacodynamic and in vivo animal infection models are now extensively used. The value of these pre-clinical experiments, combined with mathematical modeling, helps to identify a pharmacokinetic (PK)-pharmacodynamic (PD) exposure measure which best predicts the therapeutic efficacy, and to quantify the magnitude of this index required for in vivo efficacy. PK-PD target attainment analyses using Monte Carlo simulation to integrate interpatient variability in drug exposure (PK), drug potency (MIC), and in vivo exposure targets that are predictive of positive therapeutic outcomes are influencing antibacterial drug development for proof of concept, for dose and dosing interval selection, for determining susceptibility breakpoints, and for evaluating the clinical meaning of antibacterial resistance. In this article, the key concepts of antibacterial PK-PD and model based antibacterial drug development strategy and process are critically reviewed.

Integration of pharmacokinetics(PK)/pharmacodynamics(PD)in antibiotic drug development allows the dosage regimen to be optimized,so that the desired effect can be achieved in a large proportion of the target patient population.In vitro kinetic and in vivo animal models have been extensively used in the evaluation of antibiotics.The value of these pre-clinical models in the PK and PD characterization of antibiotics is critically reviewed.A model based clinical development of antibiotics with integrating MIC distribution,PK parameter distribution,the PD target from animal models of infection,and the protein binding of the test drug,is also reviewed.
8.The phlegm theory of gastric cancer.
Journal of Integrative Medicine 2011;9(6):581-587
Abstract: Based on years of ancient literature research and clinical experience, Professor Pin-kang Wei developed the phlegm theory of gastric cancer. In light of the properties of gastric cancer and the method of differentiating syndromes within the traditional Chinese medicine (TCM) paradigm, it is believed that gastric cancer is closely related with phlegm. Much ancient literature regarding the relationship between phlegm and gastric cancer was reviewed to explain the rationale and academic inheritance of the phlegm theory. In this theory, gastric cancer is regarded as a form of phlegm stagnation and consists of phlegm core, phlegm collateral and phlegm contamination. In order to explain the mechanism of development, recurrence and metastasis of gastric cancer, phlegm contamination is regarded as the most fundamental cause and pathogenesis of gastric cancer. The therapy of resolving phlegm and dispersing nodules is suggested for the fundamental treatment of gastric cancer.
10.Eight therapies of resolving phlegm and dispersing nodules in treatment of gastric cancer: experience from Professor Wei Pin-kang.
Journal of Integrative Medicine 2011;9(10):1066-9
Professor Wei Pin-kang developed phlegm theory for gastric cancer. He adopted the therapy of resolving phlegm and dispersing nodules as the fundamental therapy for gastric cancer. As the symptoms may vary due to the changes of etiology and pathogenesis at different stages of gastric cancer, he further formulated eight therapies based on the fundamental therapy, namely, resolving phlegm and regulating stomach, resolving phlegm and removing stagnancy, resolving phlegm and clearing heat toxin, resolving phlegm and relieving qi depression, resolving phlegm and dredging collaterals, resolving phlegm and removing blood stasis, resolving phlegm and promoting diuresis, and resolving phlegm to soften abdominal mass. These therapies showed satisfactory effects following the principle of simultaneous treatment of disease and symptoms.
