To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

Most Chinese medicine has good clinical efficacy and application. However, the material basis is vague for the lack of basic research, the value of Chinese medicine is hard to reflect for the low technology level and product quality is difficult to maintain for the quality control indicator selection is incorrect. Chinese medicine Jinfukang oral liquid is a typical product of Chinese medicines. Jinfukang oral liquid was selected as a model drug in this article. Based on the overall concept and systems theory of traditional Chinese medicine, the research idea and technology system for modern Chinese medicine secondary exploitation was formed. The system includes three parts, for the first, basic research to make clear the components structure and their action mechanism, for the second, technology upgraded to optimize process and improve the product quality, for the last, exploring the associated industry to form the industrial chain. The research ideas and technology system based on the material basis research and development of modern Chinese medicine, guided with component structure in Chinese medicine and aimed clinical needs. This research ideas and technology system provides strategies and methods for the development of modern Chinese medicine secondary exploitation.

BACKGROUND: Mesenchymal stem cells are the stem cells that possess the capability for self-renewal and multi-directional differentiation. Umbilical cord is the tissue outside the embryos and would be fallen off after parturition. In addition, it has wide source and no ethical restriction, so it is promising to be the first choice for mesenchymal stem cells. OBJECTIVE: To detect the surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) prior to and after cryopreservation and resuscitation. METHODS: After isolation and culture, morphology of the primary, P4 and P8 hUCMSCs was observed prior to cryopreservation and after resuscitation. Surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of primary, P4, and P8 hUCMSCs were detected through the use of flow cytometry prior to cryopreservation and after resuscitation RESULTS AND CONCLUSION: hUCMSCs prior to cryopreservation and hUCMSCs of different passages after resuscitation present the same phenotype, i.e., positive for CD29, CD44, CD49e, CD73, and CD90, and negative for CD34, CD45, CD271. These findings suggest that primary hUCMSCs do not present changes in surface markers after cryopreservation and resuscitation.

The evolution of hepatocellular carcinoma (HCC) is a compound process which involves many kinds of genes and transductional pathways. The expression of the peptidyl-proplyl-isomerase PIN1 gene, the mutation in exon 3 of beta-catenin and its correspondent abnormal expression and their roles in the hepatocellular carcinogeneisis were investigated. Among 29 pair cases of HCC and non-carcinoma tissues, the expression of PIN1 gene was detected by immunochemical staining. Mutations in exon 3 of beta-catenin gene and differential expression of beta-catenin gene were investigated by the methods of PCR-SSCP, direct sequencing and immunohistochemical technique as well. The results indicated: (1) 44.8% (13/29) cases of HCC presented higher level of PIN1 gene expression than non-cancerous tissues (chi2=32.63, P<0.05), especially in cytoplasm and nucleus, while there was lower level of PIN1 expression in non-cancerous tissues; (2) 58.6% (17/29) HCC tissues showed beta-catenin protein accumulation in cytoplasm and nucleus. 46.2% (6/13) HCC tissues indicated beta-catenin protein accumulation with higher level of PIN1 expression, while 53.8% (7/13) HCC tissues indicated beta-catenin protein accumulation with lower level or trace of PIN1 expression (chi2=0.00, P>0.05); (3) 24.1% (7/29) of primary tumor lesions carried gene mutations in exon 3 of beta-catenin, and accompanied by beta-catenin protein accumulation. There was no mutation in non-cancerous tissues. All the mutation presented in tissues with low level of PIN1 expression. There was no mutation of beta-catenin gene in tissues with high PIN1 expression level (chi2=58.12, P<0.05). So it was postulated that the increase of PIN1 gene expression could promote hepatocellular carcinogenesis via a way different from beta-catenin gene mutation.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

Objective To analyze the relationship between pre － pregnancy body mass index ( BMI) ，gestational weight gain ( GWG) and the birth weight of infants，and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia． Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester． Each respondent＇s weight before and during pregnancy and the birth weight of infant were collected after fellow up． Prepregnancy BMI was divided into underweight，normal and overweight /obesity groups and GWG was divided into suitable， insufficient and excessive groups． Multivariate Logistic regression was adopted to explore the relationship be- tween pre－pregnancy BMI，GWG and newborn＇s birth weight． Ｒesults Women＇s prepregnancy BMI and GWG were associated with neonatal birth weight ( all P＜0. 05) ． Prepregnancy overweight or obesity ( OＲ=2. 339，95% CI: 1. 674－2. 282，P＜0. 001) and excessive GWG ( OＲ= 1. 398，95% CI: 1. 188－1. 978，P= 0. 048) were shown as risk factors for macrosomia． Insufficient GWG increased LBW risk ( OＲ = 1. 479， 95% CI: 1. 461－1. 679，P= 0. 035) while excessive GWG declined LBW risk ( OＲ= 0. 428，95% CI: 0. 225 －0. 817，P= 0. 010) ． Under weight－insufficient GWG was risk factor of LBW ( OＲ= 1. 335，95% CI: 1. 048 －2. 319，P= 0. 048) while normal BMI－excessive GWG ( OＲ= 1. 088，95% CI: 1. 016－1. 675，P= 0. 038) and overweight /obesity－excessive GWG ( OＲ= 1. 498，95% CI: 1. 244－2. 017，P= 0. 046) were associated with higher risk of delivering macrosomia． Conclusions Prepregnancy BMI and GWG were associated with infant＇s birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy．

To study the effect of ligustrum fruit on spermatogenesis and blood gonadal hormones in diabetic rats.Methods: Experimental diabetes was induced in male Wistar rats with streptozotocin. Ligustrum fruit extract was given by gastric gavage at a dose of crude drug 30 g@ kg- 1@ d- 1 for 110 days. The serum gonadadotropic hormones and testosterone were determined on d 60 and testicular histology examined on d 110. Results: In the control diabetic rats, the seminiferous tubules were dilated and the spermatogenic cells irregularly arranged. Spermatogenesis was arrested with the number of spermatids highly reduced and spermatozoa not observed. In the treated rats, all types of spermatogenic cells were practically normal. The serum luteinizing hormone (LH), follicle-stimulating hormone (FSH)and testosterone levels were higher in the treated than in the control rats, but the difference was insignificant. Conclusion: In experimental diabetic rats, ligustrum fruit extract protects the damaging effect of experimental diabetes on spermatogenesis.
