Objective To investigate the safety and effectiveness of Glifeet in bowel preparation before colonoscopy.Methods A prospective,single blind,randomized controlled trial of patients undergoing colonos-copy was conducted.A total of 67 inpatients were randomized to the control group,who received a low-residue and semiliquid diet (n =31)and the experimental group,who received Glifeet all day (n =36)before the proce-dure.All patients took polyethylene glycol electrolyte powder 1 000 ml at 7 pm on the day before colonoscopy and 2 000 ml at 8 am on the examination day.Bowel preparation quality was scored using the Boston Bowel Prepara-tion Scale (BBPS).Side effects were also observed.Results The time of the first bowel movement of the experi-mental group was significantly shorter [(77.43 ±54.21)min VS (149.35 ±118.15)min,P =0.002].An in-creased defecating frequency was observed in the experimental group,but there was no significant difference when compared with the control group (11.44 ±6.95 VS 8.74 ±3.58,P =0.055).Patient tolerance and acceptance did not differ.There was no significant difference in BBPS between the two groups.But the bowel preparation quality of the right colon was significantly better in the experimental group (2.56 ±0.50 VS 2.23 ±0.81,P =0.045). Conclusion Glifeet could meet the needs of basic energy in most patients for colonoscopy.Furthermore,Glifeet is well tolerated and can partially improve the quality of bowel preparation.

OBJECTIVETo discuss the anti-tumor effect of Xihuang pill on tumor-bearing rats and its effect on the immune clearance function of tumor-bearing organisms.

METHODWalker256 tumor cells were adopted to establish the tumor-bearing rat model. The rats were randomly divided into five groups: the normal control group, the model control group, the lentinan group and Xihuang pill low dose, middle dose and high dose groups, with 10 rats in each group, and continuously treated and given drugs for 14 d after modeling. Blood and tumors were collected from abdominal aorta to calculate the tumor inhibition rate. The content of CD3+, CD4+, CD8+ T cells and adhesion molecule B7-1 (CD80) in peripheral blood were detected by flow cytometry (FCM). The expressions of IL-2 and IFN-gamma in were determined by ELISA.

RESULTThe tumor inhibition rate of the Xihuang pill high dose group was 33. 1 percent. Compared with the model group, the Xihuang pill large dose group showed significantly low IL-2, IFN-gamma, CD3+, CD4+, B7-1 in peripheral blood, with statistical significance in their differences (P < 0.05).

CONCLUSIONXihuang pill could show its anti-tumor effect by enhancing the immune clearance function and increasing IL-2, IFN-gamma, CD3+ T, CD4+ T, B7-1 in peripheral blood.

OBJECTIVETo explore the expression and clinical significance of Semaphorin4D (Sema4D) mRNA in peripheral blood lymphocyte, Sema4D on platelet surface, soluble Sema4D (sSema4D) in plasma in patients with cerebral infarction.

METHODSTaking 299 patients with cerebral infarction as the case group while 195 healthy adults as the control group. The mRNA expression of Sema4D was detected by Real-time PCR, and Sema4D expression on platelet by flow cytometry, sSema4D by ELISA. Then, the expression of Sema4D on platelet surface and the concentration of sSema4D in plasma of the 195 selected patients following 2 weeks' treatment were tested.

RESULTSThe expression of Sema4D mRNA significantly increased in the case group \[(2.23, 2.66)×10(4) IU/ml\] than in the control group \[(0.49, 0.53)×10(4)IU/ml\] (P < 0.01). The level of Sema4D on platelet surface in the case group (191.62 ± 46.56) significantly decreased than in the control group (303.33 ± 112.66) (P < 0.01). But the concentration of sSema4D in plasma in the case group \[(1.34 ± 0.56) µg/L\] was obviously higher than in the control group \[(0.61 ± 0.31) µg/L\] (P < 0.01). The expression of Sema4D on platelet was obviously relevant with the concentration of sSema4D in plasma in the case group with the correlation coefficient as 0.328 (P < 0.01). The expression of Sema4D on platelet obviously peaked up following 2 weeks' routine therapy in the case group, which was close to that in the control group. Meanwhile the concentration of sSema4D in plasma was downward corrected to the normal in the case group.

CONCLUSIONThe increased expressions and plasma levels, and reduced expressions on platelet of Sema4D in acute period, which returned to normal 2 weeks after treatment in the case group may be related to the occurrence of acute cerebral infarction, reflecting the development process of cerebral infarction.

BACKGROUNDSome larger scale, randomized studies have demonstrated the superiority of drug-eluting stents (DES) over bare metal stents (BMS) for the treatment of acute myocardial infarction (AMI). This study aimed to investigate the impact of DES, in comparison with BMS, on the 2-year clinical outcomes in patients with ST-elevation myocardial infarction (STEMI).

METHODSFrom January 2002 to December 2008, a total of 1301 consecutive STEMI patients treated with coronary stenting in Shenyang Northern Hospital were prospectively registered. Patients received BMS (n = 868) or DES (n = 435) implantation in the infarction related artery according to physician's discretion. A propensity score analysis was performed and two well matched subgroups were selected (BMS, n = 288; DES, n = 288) to evaluate the 2-year clinical outcomes. The primary outcome was the occurrence of major adverse cardiac events (MACE), which was defined as a composite of all-cause death, myocardial infarction (MI), or target vessel revascularization (TVR).

RESULTSSurvival salvage analysis showed that 2-year cumulative hazards were not significantly different between the two groups with respect to TVR (2.8% vs. 3.1%, log-rank P = 0.780), stent thrombosis (1.7% vs. 4.2%, log-rank P = 0.079) and MACE (8% vs. 10.8%, log-rank P = 0.236). Multivariate analysis showed that DES was an independent protective factor of MI (HR: 0.211, 95%CI: 0.049 to 0.908) and stent thrombosis (HR: 0.327, 95%CI: 0.107 to 0.994).

CONCLUSIONDES was associated with similar 2-year clinical outcomes to those of BMS for the treatment of STEMI in daily practice.

This study was aimed to explore the correlation of mean platelet volume (MPV), fibrinogen (FIB) and blood rheology with the youth patients with cerebral infarction, so as to provide the basis for the clinical early diagnosis and treatment. The 109 patients with cerebral infarction aged between 18 - 45 were divided into three group: the large (> 10 cm(3)), middle (4 - 10 cm(3)) and small (< 4 cm(3)) area infarction; 30 healthy persons were served as control group. All the four groups were subjected to 16 examinations, such as MPV, FIB, and rheology (Lηb, Mηb, Hηb, ηp, Lηr, Mηr, Hηr, KVE, EAI, ERI, EDI, EEI, HCT, ESR). The results showed that all the MPV, FIB and rheology indexes of the different infarction groups were higher than those of healthy control group (P < 0.05). The MPV, FIB and rheology indexes in the large area infarction group were all higher than those in the small area infarction group (P < 0.05). The indexes of MPV, FIB and rheology in the various cerebral infarction area groups obviously decreased, but those did not reach to the level in the healthy control group (P < 0.05). The MPV, FIB content and rheology level correlated with infarction areas (r = 0.36, 0.29 and 0.48, respectively). It is concluded that the serious intensity of youth patients with cerebral infarction positively correlated with the levels of MPV, FIB and rheology indexes. Regular examination of above mentioned index may be useful to prevent youth patients from cerebral infraction.

Purpose To summarize the histological,immunophenotypic feature and MYCN (MYC gene) amplification results of peripheral neuroblastic tumours in children,and to predict its biological behavior and prognosis.Methods The histology and immunophenotype of 100 cases of neuroblastoma (NB) and ganglioneuroblastoma (GNB) were retrospectively analysed,MYCN status was detected in 60 cases.Results Among The average age of 100 cases of GN and GNB was 2.7 years old,and that of males was more than that of females.NB could be divided into three subtypes:undifferentiated,poorly differentiated and differentiating.GNB could be divided into two subtypes:intermixed (iGNB) and nodular (nGNB).Immunohistochemical staining showed neuroblastoma cells were positive for NSE,NF,PGP9.5,Syn,CgA in varying degree.Schwann cells were positive for S-100 and GFAP.MYCN amplification was detected in 1 1.67％ of the cases,and no MYCN amplification was seen in iGNB patients.Conclusion The diagnosis of peripheral neuroblastic tumours is mainly based on histological morphology,special tests (immunohistochemistry,electron microscope and cytogenetics) can helpful for identifing undifferentiated neuroblastoma cells.The prognosis of neuroblastoma derived tumors is evaluated according to the age of patients,the classification and staging of tumors,and molecular genetic alterations.

Aim To screen the differential microRNA (miRNA) expression profiles of different metastatic po-tential liver cancer cell lines,and predict miRNAs-reg-ulated target genes and their functions. Methods To-tal RNA was extracted and the miRNA expression pro-files were obtained by miRNA microarray chip hybrid-ization. The miRNAs whose expression had significant difference were selected by analyzing the miRNA difference expression profiles of the two different meta-static potential liver cancer cell lines, namely MHCC-97H(high-metastasis) and Hep3B(non-metastasis), which were compared with normal hepatocytes L02 re-spectively. Moreover, we analyzed the miRNA differ-ential expression profile between liver cancer cell lines MHCC-97H and Hep3B. The miRNAs were verified by qPCR and target genes were predicted by four softwares (TargetScan, miRanda, miRWalk, miRDB). To un-derstand the biological functions of predicted target genes, bioinformatics analysis was performed. Results The miRNA microarray results showed that the ex-pression of miR-192-5p and miR-215-5p significantly increased in liver cancer cell lines (MHCC-97H, Hep3B) when compared with normal hepatocytes L02, while miR-130a-3p and miR-196a-5p were significantly reduced; compared with Hep3B, the expression of miR-224-5p markedly increased in liver cancer cell line MHCC-97H, while miR-146a-5p, miR-483-3p and miR-200b-3p were significantly reduced. The re-sults of qRT-PCR were consistent with chip results. Conclusion There are differences of miRNA expres-sion profiles in different metastatic potential liver canc-er cell lines MHCC-97H, Hep3B, and they may par-ticipate in regulating the development and invasion of hepatocellular carcinoma.

OBJECTIVE: To determine the polymorphism in +252 site of tumor necrosis factor-beta(TNF-beta) gene in patients with or without endometriosis, to evaluate the levels of TNF-alpha and TNF-beta in the serum with or without endometriosis, to explore the relation between polymorphism of TNF-beta gene and the genetic susceptibility of endometriosis, and to explore the pathogenic mechanism of endometriosis at gene level. METHODS: By polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, polymorphism on +252 site of TNF-beta gene was measured in 82 patients with endometriosis (the endometriosis group) and 80 patients without endometriosis (the control group). With the sandwich-enzyme-linked immunosorbent assay (ELISA), the levels of TNF-alpha and TNF-beta in the serum of the two groups were determined. RESULTS: The TNF-beta level in the serum in the endometriosis group with TNF-beta gene +252 site AA genotype significantly increased, compared with GG genotype (t=2.029, P<0.05); while TNF-alpha and TNF-beta level in the serum had no statistical significance in patients with other genotypes in TNF-beta gene +252 site in the endometriosis group and the control group. CONCLUSION TNF-beta gene +252 site AA genotype might be enhance TNF-beta level in the serum of patients with endometriosis.
