Object To study the chemical constituent and the bioactivity in the bark of Tsoongiodendron odorum Chun Methods By bioactive following method, the extracts of both EtOAc and n BuOH in the bark of T odorum were screened for in vitro anti tumor activity Results Five constituents were obtained Among them, three from EtOAc fraction belonged to germacranolides They were costunolide (Ⅰ), parthenolide (Ⅱ) and dihydroparthenolide (Ⅲ) The other two were from the fraction of n BuOH, one was an oxoaporphinoid alkaloid, liriodenine (Ⅳ), and the last was a furanone, 2, 3 dihydroxyl 2 methyl butylrolactone (Ⅴ) Conclusion All the above five compounds are found for the first time from this plant Compounds Ⅰ, Ⅱ, Ⅳ, and Ⅴ show the cytotoxic activities against a variety of tumor cell strains, respectively

[Objective] To screen the anticancer fraction from extract of root of Adina rubella Hance.[Methods]To separate the water extract from root of Adina rubella Hance by different solvens,then determine their anticancer activities of the different extracts in vitro with MTT method.[Results]The ethylacetate extract strongly inhibited cell proliferation of LS174T,and showed significant dosage-dependent response while the butanol extract and the chloroform extract showed low anticancer activities in vitro.[Conclusion]The ethylacetate extract is the principal anticancer extract from root of Adina rubella Hance.

Objective To compare the clinical efficiency between laparoscopic and open complete mesocolic excision for right-sided colon cancer.Methods Between January 2011 and August 2012,a total of 134 patients with right-sided colon cancer who underwent CME at Fuzhou General Hospital of Nanjing Military Command were divided into laparoscopic (71) and open (63) groups.The intraoperative parameters,pathology,postoperative course and short-term outcomes were compared between groups.The chi-test and the student t test were used for statistics.Result There were no significant differences in the length of distal (P=0.427) and proximal margin (P=0.515),tumor diameter (P =0.440) and number of lymph nodes dissected (P =0.377).Postoperatively patients were followed for up to 12 months,no significant differences were found in local regional recurrence rates (4.2％ vs 1.6％) (P =0.622) and distal metastasis rates (5.6％ vs 3.2％) (P =0.684) between the two groups.The mean operative time (P =0.134) and postoperative complication rate (P =0.977) were similar.The mean intraoperative blood loss was less (P =0.000),bowel flatus passed earlier (P =0.000) and hospital stay shorter (P =0.000) in laparoscopic than that in open group.Conclusions Laparoscopic CME has the same oncologic clearance effects and short-term follow-up result compared with open CME for right-sided colon cancer,and laparoscopic CME is minimally invasive,less bleeding,less pain and quick recovery.

Mesenehymal stem cells(MSCs)have been successfully isolated from almost all tissues in Mammals,and their multi-lineage differentiation ability leads to the attractive application of MSCs in regenerative medicine.More understanding of the biological characteristics of MSCs,the interaction between MSCs and the local environment,the molecules regulating MSC homing and differentiation have been achieved,which will benefit the effective clinical trials using MSCs as repair cells and/or vehicles for exogenous genes.

Scarce information is available about the seroprevalence of Toxoplasma gondii (T. gondii) and Neospora caninum (N. caninum) infections in goats in Hubei province, China. In the present study, the prevalence of T. gondii and N. caninum infections in goats were investigated in Hubei province, China between 2014 and 2015. A total 2007 serum samples were collected from 6 counties of Hubei province, China and were tested for antibodies to N. caninum and T. gondii by an enzyme-linked immunosorbent assay (ELISA) and an indirect agglutination test (IAT), respectively. Antibodies against T. gondii and N. caninum were detected in 13.4% and 3.9%, respectively in goats. 2% (41) serum samples were positive to both parasites. There was no apparent association of T. gondii and N. caninum infection with gender of the animals. There were significant differences of T. gondii (p < 0.01), N. caninum (p < 0.05) and both parasites (p < 0.01) infection with season. This is the first time that antibodies to T. gondii and N. caninum have been detected in goats in Hubei province, China.

The radix,leaf,flower and bud of raw medicinal materials and extraction of total alkaloids of Aconitum kusnezoffii Reichb.were all involved in this investigation.All the compositions from the samples were analyzed through fourier transform infrared spectroscopy (FTIR) combined with second derivative IR spectroscopy and two-dimensional IR correlation spectroscopy (2D-IR).It was found that the spectra of raw medicinal materials showed that the radix of A.kusnezoffii Reichb.featuring a large quantity of starch was the same as starch with the characteristic peaks at 1,155,1,070 and 1,019.The leaf,flower and bud contained the similar aromatic hydrocarbons (1,600),glycosides (1,050-1,070),while lipids were not clear.The characteristic peaks of the buds,flowers and leaves were all at 1,595 cm-1 (vibration of phenyl framework) and 1,262 cm-1 (=C-O).Therefore,it was suggested that the common compound of the three parts be diterpenoid alkaloids.Second derivative IR spectroscopy showed that the characteristic peaks of radix was stronger than those of the flower,leaf and bud at 1,712 cm-1 (C=O),which proved that the quantity of characteristic peaks in the radix was larger than those in the flower,leaf and bud.In addition,six autopeaks at 1,745,1,650,1,560 (the most strong),1,465,1,400,1,300 were detected from the radix.The similar autopeaks at 1,745,1,650,1,560 (the most strong),1,465,1,400,1,300 were found in the leaf,bud and flower.In conclusion,it was demonstrated that the macro-fingerprint infrared spectroscopic identification method provided a large quantity of the comprehensive information and entirely grasped the quality of A.kusnezoffii Reichb.Besides,FTIR and 2D-IR provided massive information of the integral structures of the radix,leaf,flower and bud of A.kusnezoffii Reichb.and verified the differences between the four parts of the herb in physical structure and the contents,laying a foundation for further systematic work.
