RESUMEN
Objective: Based on supramolecular imprinting template self-recognition theory, to lay the foundation for the in vitro channel tropism research methods of Chinese materia medica (CMM). Using alizarin as imprinting template feature monomer, in vitro affinity chromatography of different pig organs was performed to test the mechanism of alizarin belonging to the liver meridian. Methods: The liver, lungs, tongue, abdominal muscle, leg muscle groups, and other tissues of pigs, as stationary phases, were made into column chromatography. Using PBS as the mobile phase, in vitro affinity chromatography experiments with alizarin belonging to the liver meridian and white sugar belonging to the spleen meridian were conducted, the content of eluent alizarin was measured by HPLC and the content of sugar was measured by UV. By using the analysis of total statistical moment, the various chromatographic parameters and chromatography equations were obtained. Results: The chromatographic parameters for the alizarin in liver, lungs, tongue, abdominal muscles, leg muscles were as following: C0: 0.2509-4.813 mg/mL; AUC: 2.509-48.13 mg; VR: 20.42-30.77 mL; σ2: 282.6-532.7 mL2; H: 14.13-26.63 mL; n: 1.212-1.777; S: 0.759 0-1.000. In the positive control group, the adsorption capacity of liver for alizarin was the strongest, and abdominal, leg, lungs, and tongue were weakened in turn. While in the negative control group, the adsorption capacity of liver for glucose (white sugar) was not the strongest. Conclusion: The adsorption capacity of liver for alizarin is the strongest, and liver has an affinity for alizarin by the super molecular imprinting templates, and it matches the theory of meridian belonging to the liver, which would establish the in vitro channel tropism preliminary research methods of CMM.
RESUMEN
The solubility parameter determination of astrageloside from Buyang Huanwu decoction with inverse gas chromatography (IGC) method evaluation was investigated in this paper. Di-n-octyl phthalate Kwai alternative sample was used to carry out methodological study. The accuracy of the measured correlation coefficient was 0.992 1. Experimental precision measured by IGC experiments showed that the results were accurate and reliable. The sample was uniformly coated on the surface of an inert carrier and N2 gas was carrier gas, a variety of polar solvents such as isopropanol, toluene, acetone, chloroform, cyclohexane as probes. TCD detector temperature was 150 degrees C, gas room temperature was 120 degrees C. Similar headspace method was used whichever over 1 μL gas into the GC measurement, Retention time t(R), t(0) and all the parameters of air and probes molecules within the column were tested. Astragaloside solubility parameter was (21.02 ± 2.4) [J x cm(-3)] ½, literature value was 19.24 [J x cm(-3)] ½, and relevant coefficient was 0.984 5. IGC method is effective and accurate to measure ingredients solubility parameter.

The clinical therapeutic effect of acupoint catgut-embedding for simple obesity was systemically analyzed to provide reference and assistance for its clinical treatment and research. By searching in the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, clinical randomized controlled trials (RCT) of acupoint catgut-embedding for simple obesity published from Jan, 2009 to July, 2013 were collected while Revman 5. 2 software was applied to perform the Meta-analysis. Totally 19 articles were acquired with 1 658 cases involved. The effective rate was selected as primary outcome measure in 19 articles. The Meta-analysis was performed among homogeneous researches. The results indicated that compared with other therapies, pooled OR of acupoint catgut-embedding was 2.45 with 95% CI [1.81, 3.32]; in the test for overall effect, Z = 5.81, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01). In subgroups analysis, in the event of treatment session with more than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.61 with 95% CI [1.53, 4.46]; in test for overall effect, Z = 3.51, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01); in the event of treatment session with less than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.38 with 95% CI [1.65, 3.44]; in test for overall effect, Z = 4.46, implying in the treatment of simple obesity the efficacy difference of two therapies was significant (P < 0.01). Compared with electroacupuncture, OR of acupoint catgut-embedding was 1.79, 95% CI [1.08, 2.95] (P = 0.02). Compared with acupuncture, OR of acupoint catgut-embedding was 1.89, 95% CI [1.16, 3.09] (P = 0.01), which explained that compared with electroacupuncture and acupuncture, the efficacy of acupoint catgut-embedding was significantly different. In a word, the clinical efficacy of acupoint catgut-embedding is superior to other therapies in the treatment of simple obesity.
