The paper aims to elucidate and establish a new mathematic model: the total quantum statistical moment standard similarity (TQSMSS) on the base of the original total quantum statistical moment model and to illustrate the application of the model to medical theoretical research. The model was established combined with the statistical moment principle and the normal distribution probability density function properties, then validated and illustrated by the pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical method for them, and by analysis of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving the Buyanghanwu-decoction extract. The established model consists of four mainly parameters: (1) total quantum statistical moment similarity as ST, an overlapped area by two normal distribution probability density curves in conversion of the two TQSM parameters; (2) total variability as DT, a confidence limit of standard normal accumulation probability which is equal to the absolute difference value between the two normal accumulation probabilities within integration of their curve nodical; (3) total variable probability as 1-Ss, standard normal distribution probability within interval of D(T); (4) total variable probability (1-beta)alpha and (5) stable confident probability beta(1-alpha): the correct probability to make positive and negative conclusions under confident coefficient alpha. With the model, we had analyzed the TQSMS similarities of pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical methods for them were at range of 0.3852-0.9875 that illuminated different pharmacokinetic behaviors of each other; and the TQSMS similarities (ST) of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving Buyanghuanwu-decoction-extract were at range of 0.6842-0.999 2 that showed different constituents with various solvent extracts. The TQSMSS can characterize the sample similarity, by which we can quantitate the correct probability with the test of power under to make positive and negative conclusions no matter the samples come from same population under confident coefficient a or not, by which we can realize an analysis at both macroscopic and microcosmic levels, as an important similar analytical method for medical theoretical research.

OBJECTIVETo observe the effects of acupuncture-moxibustion on chronic allograft nephropathy (CAN) and explore the methods of acupoint selection along meridian for transplanted-kidney-related diseases.
METHODSA total of 180 patients of CAN were randomized into a syndrome differentiation group, a spleen-meridian group, a kidney-meridian group and a control group, 45 cases in each one. A total of 33 cases dropped out before the end of the study, including 8 cases in the syndrome differentiation group, 12 cases in the spleen-meridian group, 13 cases in the kidney-meridian group and no case in the control group. Patients in the control group were treated with conventional western medicine; based on this, patients in other three groups were treated with acupuncture-moxibustion. In the syndrome differentiation group, Qihai (CV 6), Hegu (LI 4), Guanyuan (CV 4), Feishu (BL 13), Shenshu (BL 23), etc. were selected for qi deficiency of lung and kidney; Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), etc. were selected for deficiency of qi and yin; Ganshu (BL 18), Shenshu (BL 23), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), Ququan (LR 8), etc. were selected for yin deficiency of liver and kidney; Zhongji (CV 3), Guanyuan (CV 4), Mingmen (GV 4), Guanyuanshu (BL 26), etc. were selected for yang deficiency of spleen and kidney. In addition, Sanyinjiao (SP 6), Diji (SP 8), Yinlingquan (SP 9), Xuehai (SP 10), etc. were added in the spleen-meridian group; Taixi (KI 3), Zhaohai (KI 6), Fuliu (KI 7), Ciliao (BL 32), etc: were added in the kidney-meridian group. Serum creatinine (Scr), creatinine clearance (Ccr) and 24-hour urinary protein before and after the treatment were com- pared among the four groups.
RESULTSAfter treatment, 24-hour urinary protein in the acupuncture-moxibustion groups and control group were all reduced (all P < 0.05); compared before treatment, the Scr in the spleen-meridian group was significantly reduced (P < 0.05); the difference of Ccr before and after treatment was insignificant in all the groups (all P > 0.05). Compared with the control group, 24-hour urinary protein in spleen-meridian group could relieve or recover the damage of transplant kidney induced by CAN. A new interlink may be established between the transplanted kidneys and the spleen meridians, indicating that transplanted kidney-related diseases can be treated by selecting acupoints of spleen meridian.

OBJECTIVETo study on the differences between chromatopharmacokinetics (pharmacokinetics with fingerprint chromatography) and chromatopharmacodynamics (pharmacodynamics with fingerprint chromatography) of Chinese materia medica formulae to answer the question whether the pharmacokinetic parameters of multiple composites can be utilized to guide the medication of multiple composites.
METHODOn the base of established four chromatopharmacology (pharmacology with chromatographic fingerprint), the pharmacokinetics, and pharmacodynamics were analyzed comparably on their mathematical model and parameter definition.
RESULTOn the basis of quantitative pharmacology, the function expressions and total statistical parameters, such as total zero moment, total first moment, total second moment of the pharmacokinetics, and pharmacodynamics were analyzed to the common expressions and elucidated results for single and multiple components in Chinese materia medica formulae. Total quantitative pharmacokinetic, i.e., chromatopharmacokinetic parameter were decided by each component pharmacokinetic parameters, whereas the total quantitative pharmacodynamic, i.e., chromatopharmacodynamic parameter were decided by both of pharmacokinetic and pharmacodynamic parameters of each components. The pharmacokinetic parameters were corresponded to pharmacodynamic parameters with an existing stable effective coefficient when the constitutive ratio of each composite was a constant.
CONCLUSIONThe effects of Chinese materia medica were all controlled by pharmacokinetic and pharmacodynamic coefficient. It is a special case that the pharmacokinetic parameter could independently guide the clinical medication for single component whereas the chromatopharmacokinetic parameters are not applied to the multiple drug combination system, and not be used to solve problems of chromatopharmacokinetic of Chinese materia medica formulae.

With human placed in the whole nature, by following the biologic evolution path, the property of channel structure for "imprinting template" in meridian andwas explored with supramolecular chemistry. In the history of biologic evolution, each molecule in "molecule society" gradually developed into various highly-ordered supramolecular bodies based on self-identification, self-assembly, self-organization, self-replicating of"imprinting template", and thereby the original biochemical system was established, and finally evolved into human. In the forming process of supramolecular bodies, the channel structure of"imprinting template" in guest supramolecular bodies would be kept by host supramolecular bodies, and communicate with the outside to exchange materials, energy, information, otherwise life phenomenon could not continue, for which it was the chemical nature of biolo-gical supramolecular bodies for body to develop meridian. Therefore, the human was a gigantic and complicated supramolecules body in biological nature, and possessed the supramolecules "imprinting template" at each stage of evolution, for which the meridians were formed. When meridians converged, acupoints appeared; when acupointsconverged,appeared. With the promotion of the blood from heart, according to"imprinting template", the guest supramolecular bodies and host meridian produced-analysis, which was the-phenomenon of guest in meridian. It presented asimage of physiology and pathology as well as action regularities of medication and acupuncture tolerance, by which current various meridian viewpoints could be explained and propose the hypothesis of meridian supramolecular bodies. The meridian and its phenomenon was decide by its "imprinting template" of supramolecular bodies and self-reaction regularities, which abided through the living nature. This was the substance for meridian biology.
