With the rise of microecology and medical model getting into the stage of the development of the ecological medicine, the intersection and consistency in the cognition traditional of Chinese and Western medical system are highlighted. Yin-yang theory is the core theory in TCM. In order to extend the guidance effects of theory of the balance of yin and yang in the clinic, and help TCM theory and curative effect be further recognized by the world, this article analyzed the consistency of different systems by comparing TCM balance theory and microecology, with a purpose to explore the closed link between TCM balance theory and microecology and microscopic nature of TCM balance theory.

OBJECTIVE:To establish the method for the detection of the known glucagon-like peptide 1 receptor (GLP1R) gene mutation site rs3765467(NT_007592.16,position:39065819),and to evaluate its accuracy and practicability. METHODS:Peripheral venous blood samples of 72 healthy subjects were collected in medical examination center of our hospital during Oct. 2015-Feb. 2016. The whole blood DNA was extracted by column extraction method. After amplified by touch down PCR,high reso-lution melting(HRM)method was adopted to analyze amplified product. Sequencing verification by double stranded chain termina-tion method(Sanger sequencing method)was performed for 38 test samples. The results of 2 methods were compared. RESULTS:The results of mutation scanning showed that there were 39065817 and 39065819 polymorphism sites in amplified segments. Four types of mutations were detected by HRM method [GCG/GCG,GCA/GCG or ACG/GCG,GCA/GCA or ACG/ACG,A(G) CA(G)],but 6 types of mutations was detected by Sanger sequencing method [GCG/GCG,ACG/GCG,ACG/ACG,A(G)CA (G),GCA/GCG,GCA/GCA]. CONCLUSIONS:HRM method can identify GCG/GCG and A(G)CA(G)genotype,but can not identify GCA/GCG and ACG/GCG heterozygous mutation,GCA/GCA and ACG/ACG homozygous mutation. The method is not suitable for the detection of single nucleotide polymorphism for multiple neighboring sites. In the detection of single nucleotide mu-tation,economical and simple method should be selected after comprehensive analysis of sequence.

OBJECTIVE:To provide reference for formulating related provisions,guidelines and regulations for off-label drug use,standardizing medical behavior in medical health institutions. METHODS:According to the connotation of off-label drug use,Questionnaire for off-label drug use was developed for medical institutions,in which drug name,treatment disease,the type and use evidence ofoff-label drug usewere included. The questionnaires were delivered to pharmacists who participatedClinical phar-macist practice skills training in Sichuan province to collect the related information of off-label drug use for statistical analysis, and suggestions were put forward. RESULTS:Totally 150 questionnaires were sent out,124 were effectively received with effec-tively recovery of 82.7%;the surveyed pharmacists came from 22 medical institutions,including 18 tertiary hospitals and 4 second-ary hospitals;there were 128 information about off-label drug use,including 14 (10.9%) with incomplete reporting information. The another 114 information were major in“super indication”(61) and“super administration”(43),accounting for 53.5% and 37.7%,respectively,and there are 8 other drug overdose(7.0%),2 super object(1.8%). The relevant off-label drug use mainly included anti-infection drugs (34 information,29.8%),anti-tumor drugs (16 information,14.0%),TCM injections (8 informa-tion,7.0%),and etc.;the relative concentration of varieties were metronidazole,dexamethasone,gentamicin,methotrexate, azithromycin,irinotecan,vancomycin,nystatin,etc.. Some medical institutions were absence of effective regulatory measures. CONCLUSIONS:Off-label drug use is quite common in medical institutions of Sichuan province,some of them exist obvious med-ication risk. It is suggested that the state should be as soon as possible to develop related provisions,guidelines and regulations for off-label drug use,endowing legal force for off-label drug use;medical staff should avoid no evidence-based drug use,unreason-able or even unnecessary off-label drug use;pharmaceutical production enterprises should strengthen communication with medical institutions and pay attention to collect information related to the clinical medication,timely update the drug instructions to ensure the legitimate rights for patients and the interests for medical staff.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.
