Objective To compare the quality of life at baseline and at 3 months after coronary artery bypass grafting(CABG) and investigate the related risk factors. Methods The prospective study included 121 consecutive patients reaching inclusion criteria and undergoing CABG between June 2009 and May 2016. Health status survey was measured with short form-36(SF-36)at baseline and at 3 months after CAGB. Change of quality of life and influencing factors and quality of life were analyzed. Results Eight domains including physical functioning ,role-physical ,bodily pain,general health,vitality,social functioning,role-emotional and mental health and two component summaries including physical component summary(PCS)and mental component summary (MCS)of SF-36 were significantly improved at 3 months following CAGB(all P<0.01). Moreover,advanced age, women,diabetes mellitus,assisted ventilation time,hospital stay and use of t-PA were relative to the PCS after CAGB. Conclusions The findings demonstrate quality of life is significantly improved at 3 months post CAGB. Advanced age,underlying disease,serious disease,women and lower PCS score prior to CAGB are linked with low PCS after CAGB.

Objective:To investigate the mechanisms of decoy oligodeoxynucleotides(decoy-ODN) blockading Stat3 that inhibit breast cancer cells MDA-MB-231 proliferation.Methods:Stat3 decoy-ODN and scramble control were transfected into breast cell line MDA-MB-231, respectively. The cell proliferation capability was detected by cell counting; flow cytometry was applied to detect MDA-MB-231 cell cycle; FITC labeled decoy was observed by Reflected Light Fluorescence Microscope; the expression of the gene controlled by Stat3 was examined by means of RT-PCR and Western blot assay.Results:Stat3 decoy-ODN could be internalized into MDA-MB-231 cells and inhibit the growth of MDA-MB-231 cell via inducing its apoptosis. Stat3 decoy-ODN also could significantly reduce the expression of Stat3 controlling genes such as Bcl-xl,c-myc and CylinD1.Conclusion:Stat3 decoy-ODN can inhibit breast cell line MDA-MB-231 proliferation by blockading JAK/STAT pathway. This suggests that transcription factor decoy-ODN may serve as a novel therapeutic strategy for breast cancer.

To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

OBJECTIVE:
To assess the association of C677T polymorphism of methylenetetrahydrofolate reductase (MTHFR) gene with autistic behavior and inheritance pattern of children patients.
METHODS:
Ninety three autism patients were selected as the study group, whilst 93 healthy children were selected as the control group. The C677T genotype of the MTHFR gene was determined, and the correlation between the genotype and the autistic behavior and inheritance pattern were investigated.
RESULTS:
MTHFR gene C677T locus revealed three genotypes CC, CT and TT. Compared with the control group, the study group had fewer CC genotype but more TT genotype (P<0.05). Individuals with the three genotypes showed a statistically significant difference in the frequencies of four problem behaviors (P<0.05). Regression analysis showed that at least one T allele encoding the degree of 1 and 2 for the 4 problem behaviors that were statistically different. MTHFR gene C677T genotype was associated with autism under the recessive inheritance model and allelic inheritance model (P<0.05).
CONCLUSION
The C677T polymorphism of the MTHFR gene is associated with autistic behaviors. Children with the TT genotype or T allele are at higher risk of developing autism, particularly direct gaze, complex limb movements, self-injurious behavior and hyperactivity 1 and 2 related with the degree of coding.

Fang's scalp acupuncture is mainly used in the treatment of nervous system diseases, bone and joint pain and mental diseases. It has significant effect on the early stage recovery stage and complications of post-stroke hemiplegia. The selection of acupoint is basically the same in improving patients with neurological impairment and dyskinesia, but differenct in the selection of acupoints in the treatment of complications. In recent years, it has been widely used in the treatment of children with attention deficit hyperactivity disorder and Tourette's syndrome. Fang's scalp acupuncture method was formed quite early with relatively complete theoretical system, but its clinical application is relatively insufficient. There exist some problems such as failing to reflect the theory of viscera and meridians in acupoint selection, the theory of acupoint selection by projection of cerebral cortex function, which needs to be proved further, the operation requirements are strict while the methods and practice of researchers are are differenct, and some clinical research design is not rigorous,etc.

Objective:To explore the effects of bariatric metabolic surgery on body composition.Methods:The retrospective cohort study was conducted. The clinicopathological data of 66 patients with metabolic diseases who were admitted to the Third Xiangya Hospital of Central South University from January 2013 to December 2014 were collected. There were 42 males and 24 females, aged (40±11)years, with a range from 17 to 63 years. Of the 66 patients, 27 undergoing laparoscopic sleeve gastrectomy (LSG) and 39 undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) were allocated into LSG group and LRYGB group, respectively. The body composition of all patients was determined by dual-energy X-ray absorptiometry at preoperation and postoperative 6 months. Observation indicators: (1) the changes of anthropometric parameters, glucolipid metabolism, body fat mass percentage (BF%) and the ratio of Android BF% and Gynoid BF% (A/G ratio) from preoperation to postoperative 6 months; (2) the changes of whole and local body composition from preoperation to postoperative 6 months; (3) analysis of the correlation between BF% and anthropometric parameters, glucolipid metabolism. (4) Follow-up. Follow-up was conducted using outpatient or hospitalization examination to detect the changes of body composition at the time of postoperative 6 month. The follow-up time was up to July 2015. Measurement data with normal distribution were represented as Mean± SD, paired-samples t test was used for intra-group comparison, and independent-samples t test when baseline data were consistency or covariance analysis when baseline data were not consistency was used for inter-group comparison. Measurement data with skewed distribution were represented as M ( P25, P75), and comparison between groups was analyzed using Wilcoxon signed rank test.

OBJECTIVETo optimize the protocols for isolation and culture of mesenchymal stem cells from rat bone marrow (BMSCs).
METHODSBMSCs were isolated by adherence to plastic with frequent medium change and reduced trypsinization time. The cell growth curves were drawn and the surface markers of BMSCs were detected by flow cytometry. The cells were induced to differentiate into osteogenic, adipogenic, hepatic and cholic lineages.
RESULTSThe cells isolated using this method were positive for CD29, CD44, and CD90 and negative for the hematopoietic surface markers CD45. The osteogenic and adipogenic differentiation of the BMSCs was verified by alkaline phosphatase staining, Alizarin red staining and Oil red staining. The cell subcultures up to passage 10 maintained capacities of differentiation into osteogenic and adipogenic lineages. The BMSCs induced with sequential addition of growth factors, cytokines and hormones differentiated into cells expressing hepatocyte- and cholangiocyte-specific markers.
CONCLUSIONThe optimized method allows efficient isolation of homogenous populations of MSCs from rat bone marrow, which can be induced into multiple cell lineages.

OBJECTIVE:To esta blish a method for determining the contents of lupenone and stigmasterol in the rhizome ,stem and leaf of Mosa basjoo from the same plant ,and to provide reference for the substitute resource for the effective components of M. basjoo . METHODS :UPLC method was adopted. The determination was performed on Zorbax Rrhd Eclipse Plus C 18 column (100 mm×2.1 mm,1.8 μm)with mobile phase consisted of acetonitrile-methanol (78.5∶21.5,V/V). The detection wavelength was set at 210 nm;the flow rate was 0.15 mL/min;the column temperature was 30 ℃ and the sample size was 1 μL. The results of content determination of lupinone and stigmasterol in the rhizome ,stem and leaf of 9 batches of M. basjoo from the same plant were analyzed by the methods of comparative analysis between groups ,principal component analysis and cluster analysis. RESULTS:The mass concentration of lupenone and stigmasterol had a good linear relationship with the corresponding peak area within the range of 11.16-357.10 and 8.83-160.40 g/mL(R2 were 0.999 2 and 0.999 1,respectively). RSDs of precision , repeatability and stability tests were all less than 3%. The average recovery rates of lupenone and stigmasterol were 101.44% and 98.32%,and the RSDs were 1.77% and 1.81%(n=6),respectively. The average contents of lupenone and stigmasterol in stems of M. Basjoo were significantly higher than those of rhizome and leaves of M. basjoo (P<0.05). There was no statistical significance in the contents of lupenone and stigmasterol between stem and leaf of M. basjoo from same plant (P>0.05). Results of principal component analysis showed that the contents of lupanone and stigmasterol were different in rhizome ,stem and leaf of M. basjoo from the same plant. Rhizome ,stem and leaf of M. basjoo were divided into three types through cluster analysis ,among which the rhizome had significant difference with the other two parts. CONCLUSIONS :The method is simple ,rapid,specific, reproducible and accurate. It can be used for the content determination of lupenone and stigmasterol in different parts of M. basjoo . The stem of M. basjoo can replace the rhizome of M. basjoo as the source of lupinone and stigmasterol.
