[Abstract ] Objective Bone marrow mesenchymal stem cells(BMSCs) can be induced to the differentiation into vascular smooth muscle cells in many induction conditions.We sought to explore the possibility of the differentiation of mesenchymal stem cells into vascular smooth muscle cells by continuous cell culture in vitro. Methods Rat BMSCs were isolated from the bilateral tibial and femoral bones by the method of whole bone marrow adherence, followed by ex vivo expansion.BMSCs were identified by flow cytometry and three-lineage differentiation.After continuous five days'cell culture of BMSCs, the specific surface antigens of VSMCs were detec-ted by immunofluorescence, western blot and real-time PCR. Results BMSCs expressed CD29、90, in contrast, they did not express CD45、34、49d.After induction of osteogenesis, adipogenesis and chondrogenesis, alizarin red、oil red and alcian blue staining pro-duced a strong reaction in cells.The expressions ofα-SMA、Calponin1、SM-MHC and SM22 in the cells of experimental group were no-tably increased, which indicated that BMSCs were differentiating towards VSMCs. Conclusion In the absence of exogenous stimula-tion, BMSCs can be successfully induced to differentiate into VSMCs by continuous cell culture.

ObjectiveTo discuss the changes in characteristics of N-glycan in gastric cancer and its relationship with TCM syndromes.Methods The blood samples of 138 gastric cancer patients and 120 healthy volunteers were collected. The changes in N-glycan were detected by DNA sequencer-assisted and fluorophore-assisted carbohydrate electrophoresis (DSA-FACE), and differences of N-glycan among different TCM syndromes were compared.Results At least 9 N-glycan peaks could be identified in all samples. Compared with the healthy volunteers, Peak1, Peak5, Peak9 and Peak2 of gastric cancer patients obviously increased (P<0.05,P<0.01), whereas Peak3, Peak6 significantly decreased (P<0.01). Peak6 of gastric cancer in stage I was obviously higher than stages II, III, and IV (P<0.01), while Peak9 in stage I was obviously lower than the other three stages (P<0.01). Peak1 was significantly lower in disharmony between liver and stomach type than stagnation of phlegm-dampness type, interior retention of toxin stagnation type, deficiency of both Qi and blood type (P<0.05,P<0.01);lower in impairment of yin due to stomach heat type, deficiency-cold in spleen and stomach type than deficiency of both Qi and blood type (P<0.01);lower in stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.05). Peak6 was higher in disharmony between liver and stomach type than impairment of yin due to stomach heat type, stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.01). Peak9 was much higher in deficiency of both Qi and blood type than disharmony between liver and stomach type (P<0.01), impairment of yin due to stomach heat type and deficiency-cold in spleen and stomach type (P<0.05, P<0.01).Conclusion The expression of N-glycan was specifically changed in gastric cancer. These variations could promote the metastasis of gastric cancer and potentially have certain correlation with TCM syndromes.

Objective To investigate the safety and feasibility of laparoscopic ELAPE for elderly patients with low advanced rectal cancer.Methods Totally 48 cases patients with low advanced rectal cancer surgery aged over 65 years old were analyzed retrospectively,who come from Beijing Hospital between Jan 2012 and Jan 2015.A total of 26 cases underwent Laparoscopic extralevator abdominoperineal excision (L-ELAPE) and 22 cases underwent Laparoscopic abdominoperineal excision(L-APE).Clinical data including general data,operation time,intraoperative blood loss,complications,pathological data,postoperative in hospitalization were retrospectively analyzed in patients.Results The mean operation time between L-ELAPE and APE group was (312±46)min vs.(245±62)min,mean intraoperative blood loss was(170±74)ml vs.(250± 109)ml,Operative complications was 26.9％ vs.27.3％,harvested lymph node was (16.0 ± 5.8)cm vs.(15.0±7.2)cm,intraoperative bowel perforation(IOP)rate was 0％ vs.18.2％,CRM involvement was 3.8 ％ vs.13.6 ％,mean postoperative hospital stay (days) was (13.1 ± 4.6) d vs.(13.7 ± 6.1) d.The mean operating time of L-ELAPE group was longer and mean intraoperative blood loss was much less than APE group,IOP rate and circumferential resection margin(CRM)involvement were higher in APE group(P＜0.05).Conclusions L-ELAPE is a safe and feasibility alternative approach for elder patients with rectal cancer.It is related with less intraoperative blood loss,IOP rate,CRM involvement and longer operating time contrast with L-APE.

Objective:To observe the protective effect of Yulangsan polysaccharide ( YLSP) on liver injury induced by cyclophos-phamide(CTX) in mice. Methods:Liver injury induced by CTX in mice was used as the animal model and the mice were randomly di-vided into the normal group, CTX model group, biphenyldicarboxylate ( BPDC) group, YLSP group respectively with high, medium and low dose. Except the normal group, the other groups were injected with CTX, i. p. , for 7 days to make the model. Then the ani-mals in the YLSP groups were intragastrically administered with YLSP for 7 days. The activities of alanine aminotransferase( ALT) , as-partate aminotransferase( AST) in serum, malondialdehyde( MDA) , superoxide dismutase( SOD) , glutathione( GSH) and glutathione peroxidase ( GSH-Px) in liver tissue were investigated. Hematoxylin and eosin ( HE) stain was used to study the changes in hepatic tissue of the pathological mice. Results:Compared with the model group, YLSP could obviously reduce the activities of ALT, AST and the content of MDA, and increase the content of GSH, SOD and GSH-Px (P<0. 05 or P<0. 01). HE staining showed that YLSP had significant protective effect on liver injury induced by CTX. Conclusion:YLSP has protective effect on liver injury induced by CTX.
