This article was aimed to study the intestinal absorption about main active ingredients of pectolinarin and pectolinarigenin in Carboned Cirsium japonicum DC. The absorption rate and absorption rate constant were taken as indicators. The intestinal absorption of pectolinarin and pectolinarigenin were compared by everted rat intestinal sac method among different parts of the small intestine. The results showed that the absorption rate constant of pectoli-narin among duodenum, jejunum, ileum and colon parts were 0.505 1 ± 0.192 7, 0.936 0 ± 0.187 2, 0.732 0 ±0.133 5, 0.251 3 ± 0.027 6 (μg·h-1·cm-2). The absorption rate constant of pectolinarigenin among the duodenum, je-junum, ileum and colon were 0.059 1 ±0.008 3, 0.093 3 ±0.029 2, 0.112 3 ± 0.035 6, 0.029 4 ± 0.009 1 (μg·h-1·cm-2). It was concluded that the absorption of both ingredients increased over time. The absorption of both ingredi-ents in the jejunum and ileum was higher than other parts of the small intestine. The absorption rate of pectolinarin in the entire small intestine was much higher than the absorption rate of pectolinarigenin.

BACKGROUND:Although the nickel-titanium occluder in the treatment of congenital heart disease has a better clinical effect, arrhythmia wil be more likely to develop in late stage. OBJECTIVE:To investigate the effect of nickel-titanium wire on expression of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels. METHODS:Thirty Sprague-Dawley rats were obtained and randomly divided into two groups: experimental and control groups. The nickel-titanium wire was implanted to the apex of heart of rats in the experimental group. Rats in the control group received no special treatment. Rat mycardial cels were harvested at the 1th, 3rdand 6th months after operation. The gene and protein expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels were detected using RT-PCR and immunohistochemistry, respectively. The inflammatory reactions were detected using hematoxylin-eosin staining. RESULTS AND CONCLUSION:After the nickel-titanium wire was implanted into the rat myocardium, inflammatory reaction was induced by inflammatory cel infiltration in the experimental group, with hyperplasia of fibrous tissue. The inflammatory reaction gradualy disappeared as the implanted time extended. No inflammatory cel infiltration was visible in the control group. There was no significant difference in the gene and protein expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels at different time points after operation between these two groups. It showed that nickel-titanium wire had no influence on the expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels. These results suggest that nickel-titanium occluder-related arrhythmia may have little relationship with abnormal protein expression of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor.

This experimental study was aimed to find the effect of different package and storage conditions on the content of effective components of A stragalus pieces. A stragalus pieces were stored under different storage conditions by using different packaging materials and packaging methods. Every three months, the contents of Calycosin-7-glu-coside and astragaloside were determined according to the 2010 version of Chinese Pharmacopoeia. With the extend-edstorage time, the contents of two effective components were significantly decreased. After six-monthstorage, the contents were not consistent with the standard of the pharmacopoeia standards. Room temperature had relatively big influence on the loss of content. The plastic and aluminum paperpackagingwere better than kraft paper packaging. The content ofastragaloside using non vacuum packaging method was relatively higher than the vacuum packaging. Contentunder the conditions of cool storehouse and nonvacuum plastic bags was higher than other packagingmethod. And the changes of both contents were relatively stable. It was concluded that the A stragaluspieces should be packed with non vacuum plastic bags, and stored in a cool and dry place.

ObjectiveTo analyze changes of the chemical composition in Euodiae Fructus before and after processing with Coptidis Rhizoma decoction， so as to provide scientific basis for elucidating the processing mechanism of this decoction pieces. MethodUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF/MS） was performed on a Titank C₁₈ column （2.1 mm×100 mm， 1.8 μm）， the mobile phase was 0.1% formic acid aqueous solution-acetonitrile for gradient elution， the column temperature was set at 40 ℃， the flow rate was 0.25 mL·min^-1. Electrospray ionization （ESI） was used to scan in positive and negative ion modes， and the scanning range was m/z 50-1 250. The chemical constituents in Euodiae Fructus were identified before and after processing by reference substance comparison， database matching and literature reference， and MarkerView™ 1.2.1 software was used to normalize the obtained data， SIMCA-P 14.1 software was employed to perform principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） on MS data of raw and processed products to screen the differential components before and after processing. ResultA total of 50 compounds were identified， including 48 kinds of stir-fried products with Coptidis Rhizoma decoction and 44 kinds of raw products. After processing， six compounds were added， including danshensu， noroxyhydrastinine， oxyberberine， 13-methylberberrubine， protopine and canadine. However， two kinds of compounds， including （S）-7-hydroxysecorutaecarpine and wuchuyuamide Ⅱ， were not detected after processing. In general， after processing， the overall contents of phenolic acids and flavonoids decreased significantly， the overall content of limonoids increased， and the overall content of alkaloids did not decrease insignificantly. The results of PCA and OPLS-DA showed that there were significant differences in the composition and content of the chemical components of Euodiae Fructus before and after processing， and a total of 12 variables such as quercetin， dihydrorutaecarpine and dehydroevodiamine were obtained by screening. ConclusionEuodiae Fructus stir-fried with Coptidis Rhizoma decoction mainly contains phenolic acids， flavonoids， limonoids and alkaloids. The composition and content of the chemical components have some changes before and after processing. The addition of processing excipients and hot water immersion are the main reasons for the difference， which can provide experimental basis for interpretation of the processing mechanism of this characteristic processed products of Euodiae Fructus.
