AIM: To establish the co-culture mode of tissue-engineered tracheal seeding cells, and compare with the routine culture, so as to provide the fundament of tissue-engineered trachea construction by cell compound materials. METHODS: The experiment was completed at the laboratory, Department of Respiratory Diseases, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from May 2006 to May 2007.①Three healthy New Zealand male rabbits, weighed (250.00?0.75) g, were used in this study.②Co-culture mode: The tracheal epithelial cells and fibroblasts were isolated and then co-cultured for 7-10 days. The two kinds of cells were distinguished according to their different tolerances to trypsin. Subsequently, A hole received 0.5 g/L trypsinization, cells were suspended in DMEM medium containing 0.05 volume fraction of CO2 and then transplanted into B hole (fibroblasts); again, A hole was added with 2.5 g/L trypsin for digestion, afterwards cells were suspended with K-FSM medium and transplanted into C hole (tracheal epithelial cells). Routine culture: after isolation, tracheal epithelial cells were cultured and fibroblasts were purified, respectively.③The co-cultured cells and the traditionally cultured cells were compared via cell growth curve and cell proliferation detected by 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. RESULTS: ①Cell growth: Co-cultured cells grew well, those in A hole increased intercellular apace after trypsinization, while cells in B hole were shaped as fusiform, without the manifestation of typical road stone-like cells, and cells in C hole were apposite, showing lamellar road stone-like morphology.②Cell growth curve: The growth curve of co-cultured cells was identical with that of cells by routine culture method.③Cell proliferation: MTT detection revealed no significant difference in the proliferation of co-cultured cells and cells cultured by traditional method (P

Congenital anorectal malformation(CAM) is one of the most common colorectal diseases in children. Anoplasty has been the only treatment. Because of the fact that anorectal malformation is constantly complicated with congenital defect in the nerve and musculature, postoperative difficulty in defecation is common. Poor long-term quality of life of these affected children is a burden to the children, family, and society. With the advance of modern medicine, emphasizing the functional recovery after anatomical reconstruction of anorectum and conduction of individualized biofeedback training program to improve the defecatory function and long-term quality of life are the new treatment concepts and important progress. Novel methods for the prevention and treatment of CAM are still under exploration.

Objective To observe the behavior of Schwann cell migration and wrapping up of fibres during co-culture of Schwann cells with steroframe of PLA and PLGA fibres. Methods Schwann cells were mixed into 30% ECM gel and co-cultured with PLA non-spinning fibre steroframes and seeded on one ends of PLGA fibres which were treated with collagen,polylysine or ECM. The attachment,growth and migration of Schwann cells were observed under phase contrast microscope and laser scan confocus microscope. Results (1)When Schwann cells were co-cultured with PLA steroframes,most of the Schwann cells kept in the fibre holes and attached on PLA fibres to form B?ngner band likd structures. (2)When co-cultured with PLGA fibers,Schwann cells could attach and migrate on PLGA fibres and the number of Schwann cells were obviously increased when PLGA fibres were treated by ECM. Conclusions (1)ECM gel colud promote Schwann cells attachment,growth and migration on PLA steroframes and PLGA fibers. (2)ECM gel is a good integrating substance for constructing tissue engineering bioartificial nerve.

Objective To investigate the effect of ultrasound-guided transversus abdominis plane (TAP)block on the efficacy of postoperative analgesia in parturients undergoing selective cesar-ean delivery.Methods Eighty ASA Ⅰ or Ⅱ parturients recruited for selective cesarean delivery under combined spinal-epidural anesthesia were randomly divided into two groups(n =40 each):TAP group (group T)and control group(group C).After cesarean delivery,bilateral of ultrasound-guided TAP block were performed,20 ml of 0.5% ropivacaine was injected in each side in group T,while TAP was not done in group C.Both groups received patient-controlled intravenous analgesia (PCIA)after cesarean delivery.The resting and exercise visual analogue scale (VAS)scores,Ramsay sedation score and the Bruggrmann comfort scale(BCS)score were evaluated at 2,4,6,8 and 24 h after operation. The consumption of sufentanil within 24 h after operation,the number of successfully delivered doses (D1 )and the number of attempts (D2 )within 24 hr after operation were recorded.D1/D2 was calculated.The parturients satisfaction and the adverse reactions were also recorded.Each parturient was assessed postoperatively by a blinded investigator.Results The consumption of sufentanil within 24 hr after operation,the resting and exercise VAS scores at 2,4,6 hr after surgery were significant-ly lower,while the BCS score,the value of Dl/D2 and the degree of satisfaction were higher in group T than those in group C (P <0.05).There were no adverse reactions in both groups.Conclusion Ultra-sound-guided TAP block reduces the postoperative sufentanil consumption,enhances the efficacy of post-cesarean analgesia of the parturients.Comfort and satisfaction are achieved in the parturients of the group T.

Objective To investigate the effects of adrenomedullin (ADM) on the expression of nuclear transcription factor-?B (NF-?B) in cultured human retinal pigment epithelial (RPE) cells. Methods Cultured human RPE cells were exposed to ADM with the concentration of 10 -7mol/L or lipopolysaccharide (LPS) with the concentration of 10 ?g/ml for 60 minutes. Nuclear translocation of NF-?B was determined by immunofluorescence staining. Western blotting analysis was used to check the expression of NF-?B protein. Results In cultured human RPE cells that were not stimulated, weak NF-?B positive green flurescence was localized in the cytoplasm. After exposed to ADM or LPS for 60 minutes, there was bright NF-?B nuclear staining in cultured human RPE cells. The results of Western blotting analysis demonstrated that in cultured human RPE cells that were not stimulated, a single weak protein strip with the relative molecular weight of 36?103 identified as immunoreative NF-?B could be observed. Both ADM and LPS could markedly increase the expression of NF-?B protein in cytoplasm. Conclusions NF-?B-dependent signal transduction pathway can be activated in cultured human RPE cells by ADM. ADM could induce NF-?B nuclear translocation and increase the expression of the protein in cytoplasm. NF-?B-dependent signal transduction pathway may play an importantrole in the function of ADM.
