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.

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

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 evaluate the surgical techniques,rehabilitation and the results of internal fixation performed for ankle joint fracture.[Method]One hundred and twenty-six patients with ankle joint fractures were treated with open reduction and internal fracture. According to the Danis-Weber classification,there were 12 cases of type A, 86 cases of type B, 28 cases of type C.The follow-up interview period varied from one year to five years,with an average of eighteen months.[Result]The number of patients whose results was better, good, fair and poor was 65, 44, 11 and 6.The total percent-age of good to better clinical results was 86.51%.[Conclusion]Operative treatment and rehabilitation may provide satisfactory fracture reduction and clinical results for ankle joint fracture.The opportunity selection,correct fracture pattern estimation, proper internal fixation and rehabilitation are important to achieve better long term results.

Objective To observe the effect of intravenous low intensity laser radiation (ILLLI) combined with traditional Chinese medicine on TXB2, 6-Keto-PGF1? and Ang II of the rabbits of experimental diabetic stroke. Method 35 successfully modeled rabbits, after alloxian injection for diabetes and photochemical radiation for stroke, were randomized into four treatment group-control group (B), ILIB group (C), a group with compound treatment of ILIB and TCH (D), TCM treatment group (E), and 7 unmodeled rabbits were made as the normal group (A). TXB2, 6-Keto-PGF1? and Ang II level were observed and compared. Result Compared with group B, group C and E can significantly rectify the disorderly TXB2, 6-Keto-PGF1? and Ang II, Group D was better than C and E. Conclusion ILLLI combined with TCM can effectively rectify the TXB2, 6-Keto-PGF1? and Ang II level, reduce nervous injury, cure diabetes cerebral infarction.

By comparing three cultivation techniques of Astragalus mongholicus, i. e. direct seeding, furrow erectplanting and furrow flat planting, it was found that furrow flat planting is the optimum technique. Its yield onplain ground was 1. 26kg/m' and 0. 96kg/m_2 on mountainous area- Root of the plant was longer, thicker andheavier than that produced hy other cultivation techniqlles. Its input/output ratio was l s l2' 94 on plaingrounfl and l: 9. 95 on n1ollntainous area. Therefore,it can be considered as a scientifically justifiable,economically technique for the cultivation of A. mongholicus on both plain ground and mountainous regions.

Objective To observe the changes in NO content and NOS activity of serum and the testis in Wistar rats with type I diabetes mellitus. Methods 63 rats were randomly divided into control group(C) and diabetes group(D). Diabetes was induced by intraperitoneal injection of Alloxan. Rats with diabetes were observed for 1 week(D 1), 2 weeks(D 2), 3 weeks(D 3), 4 weeks(D 4), 5 weeks(D 5), 6 weeks(D 6), 7 weeks(D 7) and 8 weeks(D 8), respectively, and they were sacrificed at the end of each observation period. Serum was obtained and testis homogenates were prepared, and the levels of NO content and NOS activity of them were determined respectively. Results Compared diabetes group with control group, NO contents and NOS activity of serum from diabetic rats were higher, then NOS activity began to decline to approach the control level. In the testis homogenates, NO content dropped slightly after injection of Alloxan, while NOS activity showed no significant change. Thereafter, both NO content and NOS activity of testis homogenates were increased. Conclusion There are changes in NO content and NOS activity of serum and testis of rats after diabetes are induced with Alloxan.
