Objective: To screen high-affinity short peptides of the transforming growth factor beta typeⅡ(TGF-? Ⅱ) receptor from the phage display 12-mer peptide library.Methods: The recombinant solube human TGF-? Ⅱ receptor was used as the target to screen its affinity short peptides from the phage display 12-mer peptide library.The positive phage clones were obtained by 3 rounds of biopanning,followed by single stranded DNA extraction and sequence analysis.Results: Four nucleotide sequences were obtained from 10 positive phage clones with high-affinity TGF-? Ⅱ receptor.Neither conservative nor homologous sequence was found by sequence analysis compared with the transforming growth factor beta 1.Conclusion: Phage short peptides have been screened from the phage display library,which helps pave the ground for further researches on affinity short peptides and their role in inhibiting hepatic fibrosis.

Through the practice of outpatient doctor station cored by the outpatient Electronic Medical Records (EMR),the paper discusses the disadvantages of outpatient paper medical records and the advantages of outpatient EMR,summarizes the key points and difficulties in promoting outpatient EMR,and meanwhile points out to pay attention to the integration with other information system,data standardization,perfection of the management system,integrated consultation system and other issues in the practice process.

Objective To analyze the complications caused by microwave ablation for hepatic cavernous hemangiomas, and to discuss the prevention and treatment of the complications. Methods During the period from July 2009 to May 2011 at authors’ hospital, a total of 34 times of microwave ablation procedure were carried out in 30 patients with hepatic cavernous hemangiomas. The microwave ablation-related complications were recorded and the prognosis was evaluated. Results Serious complications occurred in 2 patients (6.7%), including acute hemolysis leading to acute renal failure (n = 1) and abdominal wall abscess (n = 1). Postoperative fever was seen in 18 cases (60%), transient hemoglobinuria in 4 cases (13.3%), nausea with vomiting in 5 cases (16.7%), marked pain at the surgical area in 8 cases (26.7%), right pleural effusion in 4 cases (13.3%), hepatic dysfunction in 24 cases (80%) and leukocytosis in 11 cases (36.7%). No treatment-related death occurred. Conclusion For the treatment of hepatic cavernous hemangiomas, microwave ablation is minimally invasive with higher safety and satisfactory effect, although this technique carries somewhat higher risks when the hemangioma is larger or the location of the hemangioma is anatomically complicated. Some of these complications can be early detected and proper management should be actively adopted in order to avoid as well as to minimize the adverse results.
