Artificial ureter has been studied for nearly 60 years, however it is still in experimental stage. So far there are no commercially available products for clinical use except autologous intestines loop even though many progresses have been made. Each approach for making artificial ureter has its own inherent advantages, disadvantages and limitations. But some approaches have shown great potential to be used as ureteral substitutes. Preventing the conduit from salt depositing and ensuring a watertight anastomoses with native tissues are the key factors in designing and manufacturing the prosthetic ureter. Along with scientific and technical improvement, artificial ureter will be successfully used in clinical therapeuticsin in the very near future.

The effect of hyperestrogenemia induced by intramuscular injectied estradiol (E_2) on myocardial contractility and relaxation was observed in female rats with myocardial infarction (MI). The results showed that: (1) In MI group, the plasma estradiol level increased slyghtly and then droped, while the level of estradiol increased markedly in rats treated by E_2 in MI (MIE_2) group. (2) Diameter of myofibril in MIE_2 grows more than that of control sham operation(CS) and MI (10.65?0.59 VS 7.65?0.40 and 10.15?0.54?m, P

Objective To explore the method of repairing foot soft tissue defects by using island skin flaps pedicled with sural nerves and vessels. Methods 24 patients with foot soft tissue defects were treated surgically. The defects were repaired with island skin flaps pedicled with ipsilateral sural nerves and vessels. Results Of all the 24 flaps, 21 flaps survived at the first intention. Partial necrosis appeared in 3 flaps but were cured at the second intention. The follow ups of 1 to 2 years showed that the appearance and function were satisfactory in all the cases except 4 in which the skin appeared swollen. Conclusion To repair foot soft tissue defects, this flap has the advantages of strong anti infection ability and good texture so that healing at the first intention and early functional recovery can be obtained.

Objective To explore the distribution features of pathogenic spectra and antibiotic resistance of the isolates from blood cultures in hospital from June 2012 to June 2016.Methods A total of 4 238 blood samples from June 2012 to June 2016 were evaluated by BD Bactec FX-200,the identification results were used for retrospective analysis.Results A total of 455 positive pathogens were isolated from 4 238 blood cultures sample,the positive rate was 10.74％,Gram-positive accounts for 38.02％,Gram-negative bacilli accounts for 60.00％,Fungi accounts for 1.98％.Positive pathogens were distributed in newborn baby and middle-older patients,accounting for 6.78％ and 76.17％respectively.Which the Enterobacteriaceae accounting for 54.10％,the major consists were Escherichia coli and Klebsiellapneumoniae;Non-fermentative bacterial which consists of Pseudomonas aeruginosa and Acinetobacterbaumannii accounting for 2.90％.The major pathogens in Gram-positive cocci was Staphylococcus,accounting for 25.87％.Enterobacteriaceae were more sensitive to Meropenem,Imipenem and so all.Non-fermentative bacterial were more sensitive to Piperacillin/Tazobactam.Staphylococcus were more sensitive to Vancomycin and Linezolid.Streptococcus were sensitive to Vancomycin.Conclusion Combined with the distribution features of pathogenic spectra and antibiotic resistance,clinicians should pay attention to use of drugs reasonably to enhance the cure rate of bacteremia and Fungalemia.

Objective To determine the clinical value of intraoperative cholangiography in mini-cholecystectomy. Methods The clinical data of 506 patients receiving intraoperative cholangiography in minicholecystectomy from 1992 to 2006 in our hospital were analyzed retrospectively. Results Intr-aoperative cholangiography was successfully completed in 403 patients. The success rate was 97.4%.Stones in the bile duct in 49 patients,abnormal bite duet in 4 patients and bile duct injury in 4 patient were found. The cuts were extended in 16 patients. Conclusion Intraoperative cholangiography is of great value in inducing postoperative complications and improving the quality of MC. Therefore, it can be used to prevent residual stone after operation, avoid bile duct exploration or injury, decrease the chance of extending the cut and make sure of abnormal bile duct.

Objective To investigate a safe, highly efficient and rapid skin expansion method. Methods Syringe pump and pump control of automatic (PCA) replacemented normal affusion were used with shorter and vertical skin professional jargon for continuous and constant pressure skin expansion. Twenty cases (23 expanders) were carried out in this way. Results The maximum area of defect was 16 cm?20 cm, and the minimum area of defect was 3 cm?3 cm. The expanders were used for 18 days and the volume of expanders were 40-900 ml . It was more rapidly than normal affusion. There were no more complications except a case of expander leakage, and others expressed their satifactions Conclusion This modification of the skin expansion is a safe, comfortable, convenient to carry with. It is worth recommendation.

Objective To evaluate intravesical instillation of epirubicin plus BCG to prevent recurrence of transitional cell cancer of bladder after surgical management. Methods A total of 44 cases of bladder cancer who underwent TURBT or partial cystectomy were divided into 2 groups.①Group 1 received intravesical instillation of epirubicin plus BCG (24 cases).Within 1 week following operation single dose of intravesical epirubicin instillation was given and from the second week regular intravesical BCG was instilled afterwards.②Group 2 received BCG alone (20 cases).Within 1 week after surgical management regular intravesical BCG instillation was given. All the patients were followed up for 24 months. Results In Group 2,3 cases had recurrence at 5,9,12 months individually,the incidence rate being 15% (3/20).No recurrence developed in Group 1.The recurrence rate was significantly different between the 2 groups (?2 test,P

[Objective]To observe the clinical effect of the treatment of hyperplastic nonunion of the tibia with interlocking intramedullary nailing,fascia pedicled callus flap and bone grafting.[Method]Twelve cases of nonunion of the tibia were treated with intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting,and there were 8 males and 4 females.The patients age ranged from 26 to 64 years,with an average of 45 years.[Result]All cases were followed-up for an average of 48 months and achieved a solid union within 4～6 months.[Conclusion]Intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting have the design of the reasonable biomechanics,the function of untispinning and unticurtailing,less partial blood decompose.The fascia pedicled callus flap and iliac bone grafting could result in solid union and it is a recomment method for promoting bone-healing up after grafting and forming.

To observe repair of dental defect and its curative effect of the vertical root split of molar in the seniors, every affected section of 36 cases (40 teeth) of the senior's root split was extracted by hemisection, the other sections of them were repaired by either complete crown restoration (15 cases) or fixed bridge restoration (21 cases). The results showed that after 6～12 months, excellent curative effect was achieved in 32 cases, good curative effect in 3 cases, poor curative effect in 1 case. Significant difference was found between the two repair methods( P

The patient was treated as pharyngeal foreign body sensation for six months. Laryngeal endoscopy: one about 1 cm x 2 cm x 2 cm, hard, smooth bulge in hypopharyngeal wall at the plane of epiglottis valley. The cervical MRI showed that the C3-C4 disc herniation and degeneration of the C3-C4 vertebrae. Cervical CT showed the C3-C4 disc osteophyte formation and forward bulge. After orthopedic consultation, the patient was diagnosed as esophageal cervical spondylosis. C3-C4 diskectomy and vertebral interbody bone grafted with plate fixation were undertaken. At postoperational day 2, the pharyngeal foreign body sensation disappeared.
