In this article, we report the pancreatic islet cells function of newborn pig pancreatic tissues cultured by Ham F_(10), and the condition of graft survived into the bodies of Sprague-Dawley rats, and also study the influence of Glycyrrhiza uralensis to the grafts. The cultured islet cells of newborn pig were transplanted into the mesenteric cavities (the first & second group), kidney cystic(the third group) and brain tissucs (the fourth group) of the 4 groups adult Sprague-Dawley rats. The first group rats drank Glycyrrhiza uralensis water, after 8～11weeks of operation a examination pathological was made with the cut graft The results showed that the first and second group grafts survived over 11weeks, and survived better the group drunk the Glycyrrhiza uralensis water was much better than other. The purpose of this experiment is to find the heteropolar source of pancreatic tissues offering body.

Objective: To analyze and compare the difference in volatile components in Achyranthesbidentatae Radix, salt-pro-cessed product of Achyranthes bidentatae Radix and wine-processed product of Achyranthes bidentatae Radix.

Results:A total of 38 chemical components were identified, and 23, 16 and 15 components were respectively identified from Achyranthes bidentatae Radix, the salt-processed product of Achyranthes bidentatae Radix and the wine-processed product of Achyranthes bidentatae Radix accounted for 79. 14%, 49. 80% and 44. 57% of the total content of volatile components, respectively. There were 4 types of common volatile chemical constituents in the three products. Compared with Achyranthes bidentatae Radix, 10 types of new compounds were produced and 17 types of old compounds disappeared in the salt-processed product, and 9 types of new compounds were produced and 17 types of old compounds disappeared in the wine-processed product.

Objective: To establish an HPLC fingerprint of Caryophylli flos. to provide reference for the overall quality evaluation of the herb. Methods: The fingerprint of Caryophylli flos. was established by HPLC, and eugenol was used as the reference peak for the exploration of HPLC conditions. The fingerprint of Caryophylli flos. was established with acetonitrile-0. 2% phosphoric acid as the mobile phase with gradient elution. Results: A total of 17 characteristic common peaks were obtained by HPLC analysis, and among them, five common constituents including eugenol, ferulic acid, quercetin, kaempferol and isorhamnetin were calibrated. The similari-ties of chromatographic fingerprint of Caryophylli flos. from 10 different origins were above 0. 900, which was in line with the basic re-quirement of fingerprint similarity evaluation. Conclusion: The study provides experimental basis for improving the quality evaluation system of Caryophylli flos. , and provides reference for a comprehensive quality assessment of Caryophylli flos. .

Background and purpose: Long non-coding RNA small nucleolar RNA host gene 5 (lncRNA SNHG5) plays a cancer-promoting role in many cancers, however its effect on colorectal cancer (CRC) and its regulatory mechanism are not clear. This study aimed to explore the mechanism of lncRNA SNHG5/miR-26a-5p/metadherin (MTDH) signal axis promoting metastasis of CRC. Methods: The data of The Cancer Genome Atlas (TCGA) database was analyzed, the abnormal expression of lncRNA in CRC was explored and analyzed the survival. Samples of CRC, paracancerous tissues and complete clinical data of patients who underwent surgical resection from October 2020 to October 2021 were collected. The expression levels of SNHG5 and miR-26a-5p in lncRNA were detected by real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR), and the expression level of MTDH was detected by immunohistochemistry. The relationship between the relative expression level of lncRNA SNHG5 in CRC and clinicopathological features and survival time was analyzed. The effects of lncRNA SNHG5 on the proliferation, migration and invasion of CRC cells were detected by cell counting kit-8 (CCK-8), clone formation, scratching assays, transwell test and in vivo xenotransplantation. The relationship between CRC cell metastasis, the expression level of epithelial-mesenchymal transition related molecules and lncRNA SNHG5 expression level by Western blot and immunohistochemical detection were explored. The physical interaction between SNHG5 and miR-26a-5p, MTDH and miR-26a-5p was studied by RNA pull-down test, double luciferase reporter gene detection and RNA co-immunoprecipitation. The functional relationship among the three was verified by CCK-8, EdU and transwell experiments. The effect of SNHG5, miR-26a-5p and MTDH expression on migration and invasion related molecules was analyzed by Western blot. Results: The results of TCGA database analysis showed that lncRNA SNHG5 was significantly upregulated in CRC. The results of RTFQ-PCR and immunohistochemistry showed that the levels of lncRNA SNHG5 and MTDH in CRC tissues were significantly upregulated (P＜0.05), the level of miR-26a-5p was decreased (P＜0.05), and the level of MTDH in samples with high expression of SNHG5 was also increased. The expression of lncRNA SNHG5 in CRC tissues with serosa and extraserosal invasion, distant metastasis, lymph node metastasis and TNM stage Ⅲ was significantly higher compared with subserosal invasion, no distant metastasis and lymph node metastasis and TNM stage Ⅰ-Ⅱ (P＜0.05). The results of survival analysis showed that the high expression of lncRNA SNHG5 was significantly correlated with overall survival rate (P＜0.05). Overexpression of lncRNA SNHG5 could enhance the proliferation, clone formation, migration and invasion of CRC cells, promote the growth and lung metastasis of transplanted tumor, increase the relative expression level of Ki-67 proliferation index and vimentin (P＜0.05), and decrease the relative expression level of E-cadherin (P＜0.05). However, the development of CRC cells was inhibited after inhibition of lncRNA SNHG5 expression. RNA pull-down test, double luciferase reporter gene detection and RNA co-immunoprecipitation confirmed the physical interaction between SNHG5 and miR-26a-5p, MTDH and miR-26a-5p. Upregulation of miR-26a-5p or downregulation of MTDH expression in lncRNA SNHG5 overexpressed cells partially reversed the effects of lncRNA SNHG5 on proliferation, migration, invasion and expression of related molecules in CRC cells. Conclusion: LncRNA SNHG5 is upregulated in CRC tissues and cells, and its high expression is related to tumor progression and poor survival. It can be used as a molecular sponge of miR-26a-5p to regulate the expression of MTDH to promote the proliferation and metastasis of SW620 cells.

OBJECTIVE To compar e the volatile components of Cuscuta chinensis and its processed products ，and to conduct principal component analysis （PCA）. METHODS The volatile components of C. chinensis ，C. chinensis stir-frying with saltwater ， C. chinensis stir-frying with wine were identified by headspace solid phase microextraction combined with gas chromatography- mass spectrometry. The relative percentage of each component was calculated by area normalization method. The PCA was conducted by using SPSS 21.0 software. RESULTS A total of 117 compounds were identified from C. chinensis ，C. chinensis stir-frying with saltwater and C. chinensis stir-frying with wine ，of which 68 compounds were identified from C. chinensis （relative percentage of 92.41％），such as phytone ，2-methoxy-3-（2-propenl）phenol，n-pentadecane，β-caryophyllene. Sixty compounds （relative percentage of 89.41％） were identified from C. chinensis stir-frying with saltwater ，such as maltol ，2，3-dihydro- benzofuran，4-vinyl-2-methoxyphenol. Fifty-eight compounds （relative percentage of 87.02％）were identified from C. chinensis stir-frying with wine ，such as phenylethanol ，β-caryophyllene，macrocarehe D. There were 24 common components in the three ， and relative percentage of them were 38.56％，30.61％，33.07％，respectively. After processing ，there were 49 new components ， such as furfural ，n-hexanoic acid ，caryophyllene oxide. The results of PCA showed that the cumulative contribution rate of the former two principal components was 100％ ；comprehensive score of volatile components of C. chinensis was the highest ， followed by C. chinensis stir-frying with wine and C. chinensis stir-frying with saltwater. CONCLUSIONS The quality of volatile components in C. chinensis is good ；the volatile components in processed products are more than those in C. chinensis .
