A novel antimicrobial peptide, named as perinerin (GenBank accession No. P84117), was isolated and characterized from Asian marine clamworms, Perinereis aibuhitensis Grube. Perinerin showes powerful and broad activity against both grampositive and gramnegtive bacteria in vitro, especially on Pseudemonas aeruginosa. To obtain large amounts of active perinerin and characterize its main physiochemical features, The perinerin weve expressed in Pichia pastoris. Intact perinerin gene amplified by the modified gene SOEing method(Gene splicing by overlap extension)was cloned into expression vector pPICZ?A and obtained recombinant vector pPICZ?APEN, then pPICZ?APEN was expressed in the Pichia pastoris GS115. The expressed sample was analyzed by TricineSDSPAGE. The results showed that Pichia pastoris was a suitable system producing the secreted form of perinerin. Bioactivity assay showed that the recombinant perinerin had marked antimicrobial effects.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.

OBJECTIVETo evaluate the feasibility and safety of patient controlled analgesia (PCA) technology during double balloon endoscopy(DBE) inspection.
METHODSAccording to the anesthesia, 120 patients with suspected intestinal disease were randomized into non-anaesthesia(Group A), propofol infusion with TCI vein pump(Group B), and remifentanil vein infusion with PCA pump(Group C), with 40 patients in each group. The feasibility and safety of the three methods in double balloon endoscopy(DBE) inspection were evaluated.
RESULTSThe tolerance in groups B and C was good and the procedure success rate was 100%, significantly higher than Group A(80%, 12/40, P<0.01). The fluctuation of blood pressure, heart rate, and oxygen saturation was significantly greater in groups A and B, while patients in Group C remained stable. The detection rate was 67.5%(27/40) in Group B and 72.5%(29/40) in Group C, significantly higher than that in Group A(37.5%, 15/40, all P<0.01). The depth of endoscope was longer and the length of hospital stay shorter in Group C as compared to Group B(both P<0.05).
CONCLUSIONThe application of PCA technology in the double-balloon endoscopy inspection can meet the individualized analgesic needs of patients in different period, increase the tolerance and compliance of patients to the inspection, facilitate patient-operator communication and positions change, reduce the operation risk, and increase the success rate of double balloon endoscopy.

OBJECTIVETo investigate the clinical features of children with incomplete Kawasaki disease (IKD), and to provide reference for the early diagnosis of IKD.
METHODSThe clinical data of 22 hospitalized children with IKD were analyzed retrospectively and compared with the data of 63 children with Kawasaki disease (KD) who were hospitalized during the same period of time. Another 20 children with pyrexia were enrolled as the control group.
RESULTSPyrexia was observed in all children. Compared with the KD group, the IKD group had significantly lower proportions of children with changes in the limbs, conjunctival hyperaemia, and cervical lymphadenectasis (P<0.05), a significantly higher serum level of glutamic-pyruvic transaminase (P<0.05), and significantly lower levels of plasma albumin, serum sodium, and interleukin-6 (P<0.05). There was no significant difference in the rate of γ-globulin application between the IKD and KD groups; however, the IKD group had a significantly higher incidence rate of coronary artery lesion than the KD group (P<0.05).
CONCLUSIONSThe symptoms and signs in children with IKD are untypical. The liver function test and serum hyponatremia and IL-6 measurements may be useful for the diagnosis of IKD.
