Objective: To obtain the bFGF mimic peptide binding to FGFR via phage display, and to provide the base for developing peptide agonist of bFGF. Methods: Using Balb/c 3T3 cells as the target cells and COS-7 cells as the subtractive panning, the phage display heptapeptide library was biopanned for 4 rounds to obtain the single phage clones. The affinity and the specificity of the clones were assessed by ELISA. DNA sequencing was applied to further analyze the positive clones. Results: Twelve positive clones were selected from the enriched phages. A group of hydrophobic peptides containing a conserved motif, PR, was identified. Conclusion: Two bFGF mimic heptapeptides binding to FGFR were selected, which may be used as the candidates for bFGF agonist.

This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Objective To investigate the uptake of 99Tcm-hydrazinonicotinamide-D-alanine-D-alanine-alanine-proline-arginine-proline-glycine (HYNIC-A(D) A(D) APRPG) in rabbit models of inflammation and VX2 tumor xenografted, so as to evaluate its use as a new tracer for tumor angiogenesis. Methods Ten rabbit models of xenoplanted VX2 tumor and inflammation were randomly divided into two groups which were injected with different injected tracers, 99Tcm-HYNIC-A(D) A (D)APRPG 99Tcm-RGD, followed by serial Gamma images at various time points. The first group underwent 18F-FDG PET ahead of 99Tcm-HYNICA(D)A (D) APRPG SPECT. Analysis of variance and t-test were performed with SPSS 10.0. Results 99TcmHYNIC-A(D) A (D)APRPG scan showed negative uptake at inflammation focus but positive uptake at tumor. Pathological examination confirmed high 99Tcm-HYNIC-A(D)A(D) APRPG accumulation in tumor cells, with the highest tumor/inflammation ratio (3.25 ±0. 171) at 2 h post-injection, which was significantly higher than that of 99Tcm-RGD (2.37 ± 0.076) (F = 15. 63, P<0. 01). The tumor/inflammation ratios of 99Tcm-HYNIC-A(D)A(D)APRPG, 99Tcm-RGD, 18F-FDG were significantly different at 0.5, 1,2,3, 6 h (F = 13. 83～26. 41; t = 23.84, 12.75; all P<0. 01). Conclusion 99Tcm-HYNIC-A (D) A (D)APRPG can be used as a potential tracer for tumor angiogenesis.

OBJECTIVETo study the efficacy and safety of cellulose for the treatment of functional constipation in children.

METHODSA prospective, self-controlled, clinical trial using cellulose was conducted for 2 weeks in 34 children with functional constipation. The constipation symptoms and the characteristics of feces after the treatment were observed.

RESULTSThe characteristics of feces and the constipation symptoms were improved significantly after the treatment. The total efficacy rate was 37% 3 days after treatment, 87% 7 days after treatment and 90% 14 days after treatment. The satisfactory rates of doctors and children's parents on the therapeutic effects were 57% and 63%, respectively. No adverse events, such as abdominal distention, pain or diarrhea, were observed during the treatment.

CONCLUSIONSCellulose is effective and safe in the treatment of functional constipation in children.

To silence the expression of K-RASAsn12 in human pancreatic cancer cell line by vector-based RNAi(RNA interference) technique,two single-strand DNA sequences encoding mutant-specific shRNA (short haipin RNA) for K-RASAsn12 were synthesized and then inserted into pSilenCircle. The recombinant plasmid was called pSC-K-RASAsn12. According to the same method, pSC-GFP encoding shRNA for GFP was gained. Both recombinant plasmids were transfected into human pacreatic cancer cell line AsPC-1 and BxPC-3. The expression level of K-RASAsn12 was detected by semi-quantitative RT-PCR and Western blot. The result indicated that the recombinant plasmid edcoding mutant-specific shRNA for K-RASAsn12 can inhibit significantly the expression of K-RASAsn12 without affection of wild-type K-RAS(K-RASWT)in Human Pancreatic Cancer Cell Line.

Objective To investigate the clinical significance of serum cytokines concentrations and A- PACHE scores in evaluating the illness state for critical trauma patients.Methods A clinical prospective self-control trial was performed,in which 36 patients admitted to ICU by SIRS were enrolled.Objects were divided into mild and severe trauma group according to APACHE score.The TNF-?and IL-6 concentrations were determined on the 1st, 3rd and 5th day of admission,the APACHE score were assessed at the same time.Statistic analysis was performed according to this group.Results The TNF-?concentrations decreased continuously in the following days while IL-6 decreased from the 7th day in the mild trauma group.In the severe trauma group the TNF-?and IL-6,APACHE score concentrations kept increasing.There was a significant difference of TNF-?and IL-6 concentrations between severe trauma and mild trauma group.Conclusion Dynamic measurement of TNF-?and IL-6 concentrations with APACHE score provide great help to evaluate the illness state and predict the prognosis.

OBJECTIVETo investigate the relationship of hepatitis C virus (HCV) serotype with genotype.

METHODSThe serotypes of HCV in the serum of 104 patients with chronic hepatitis C from 14 cities in China for which HCV genotypes were available, were determined by ELISA using Murex HCV Serotyping 1-6 Assay.

RESULTSThe serotypes of 86 (82.69 percent) of the 104 serum specimens were determined, and HCV serotypes were determined for 91 strains. Overall the concordance between hepatitis C virus serotype and genotype was 62.1 percent, and the concordance of serotype, with genotypes 1, 2 and 3 were 69.4 percent, 51.2 percent and 70.0 percent, respectively. The false-negative rate and concordance of genotype 2b was lower (54.5 percent).

CONCLUSIONThe specificity of HCV serotyping was affected by HCV strains' genotype and sometimes HCV serotype was not in concordance with genotype.
