Objeetive To investigate the relationship among social avoidance and acceptance of disability in burn patients.Methods Totally 127 patients were investigated using Social Avoidance and Distress Scale (SADS),Acceptance of Disability Scale (AODS),demographic information questionnaire and disease related information sheet.Results The points of burn patients' SADS was (21.38±6.75),One-way ANOVA showed that gender,marital status,special parts burns,amputation affected social avoidance significantly.The total score and factors scores of acceptance of disability were all negatively related to the score of social avoidance.Regression analysis showed that acceptance of disability,head burns,gender were the independent risk factors of depression.Conclusions Acceptance of disability were negatively related to social avoidance; Nurse can help them accept the reality of disability,develop the confidence to partici-pate in social communication,and improve the social adaptability.

OBJECTIVETo discuss the method for repairing the circular scar in the forearm.

METHODSLarge expander (400-600 ml) were implanted subcutaneously at the rear flank of bottom-waist in the way of overlapping or continued expansion. After expansion was completed, the horizontal opened omega-shaped flap was formed by advancement of expanded skin with the two pedicles at the two sides. Then the forearm was tunneled under flap with the wound covered by flap. The pedicles were cut off at the third stage.

RESULTSFrom April 1998 to June 2009, 8 cases were treated with no flap necrosis. The patients were followed up for 1 to 3 years with good flap color and thickness. Flap sensory was partially recovered. Linear atrophic scar was left in the donor sites.

CONCLUSIONSIt is feasible to repair forearm circular scar by expanded double-pedicle omega-shaped flap at the rear flank of bottom-waist.

Objective To evaluate the applications of magnetic resonance cholangiopancreatography (MRCP) after fat meal in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty cases of the preoperative donors for living liver transplantation were included and all had the corresponding intraoperative cholangiography (IOC) information. The MRCP of the donors for living liver transplantation was performed before and after fat meal (two fried eggs). The visualization and diameter of the secondary bile duct were analyzed before and after the fat meal. The results of the biliary branching pattern by MRCP after fat meal were compared with the corresponding IOC results. The accuracy, sensitivity,specificity, positive predictive value and negative predictive value of MRCP after the fat meal in distinguishing normal and any type of variant biliary anatomy were calculated. Results In all cases,82% of the 50 cases in MRCP before the fat meal could meet the diagnosis needs of the preoperative evaluation,and 100% of the 50 cases in MRCP after the fat meal could meet the diagnosis needs. There was significant difference in the demonstration quality and diameter of the secondary bile duct in MRCP before and after the fat meal (P＜0. 05). MRCP showed accurate anatomy of the biliary system, using IOC as the reference standard, in 49(98%) subjects. The sensitivity, specificity, positive predictive value and negative predictive value of MRC in distinguishing normal and any type of variant biliary anatomy were 98%,94. 7%, 100%, 10% and 96. 9%,respectively. Conclusion The MRCP after fat meal can clearly demonstrate the secondary bile duct and perfectly meet the needs of the preoperative evaluation of the living liver transplantation. The MRCP after fat meal and routine MRCP should be considered complementary to one another in order to avoid complications in living liver transplantation donors.

OBJECTIVETo explore the clinical application characteristics of sural neurocutaneous island flaps.

METHODSSural neurocutaneous island flaps were used to repair the skin defect accompanied bone and tendon exposure in the lower leg, around the ankle and foot in 21 cases, including 4 cases to repair the foreside of the foot back . Direct flap was used in 5 cases and reverse flap in 16 cases. Meanwhile the coverage and formation of sural nerve were surveyed together with the starting point of peroneal perforator.

RESULTSAll the 21 sural flaps were survived, including sural nerve (18 cases) anastomose 12 cases, single trunk 4 cases, double trunk 2 cases. The anastomose site of medial sural cutaneous nerve and the communicating branch of lateral sural cutaneous nerve was at the point of 11 - 14 cm above the ankle in 12 cases. The lower was the anastomose site, the shorter was the sural nerve. The site is 4 - 7 cm above the ankle in 15 out of 18 sural nerve perforator branch cases, and the other 3 cases is 10, 11, 11.5 cm above the ankle respectively.

CONCLUSIONSSural neurocutaneous island flaps are easy to separate. Major arteries are not injured. It is the ideal flap to repair the skin defect accompanied by bone and tendon exposure in lower leg, around ankle and foot. The nerve must be anastomosed when repairing the heel.

OBJECTIVETo explore the clinical application of the expanded cross-leg flap for repairing instep soft tissue defects with bone exposure.

METHODSThe expanded cross-leg flap was used to repair instep defects in 10 patients. After flap transferring the donor site was closed directly without skin grafting.

RESULTSSatisfactory results were achieved in all the cases. The flaps survived well. The donor site had less scar and kept good appearance.

CONCLUSIONSThe expanded cross-leg flap is a better choice for repairing the soft tissue defects of the instep. It is simple and easy with less trauma to the donor site. After the operation, both the recipient and the donor areas had good appearance.

To investigate a baculovirus insect cell system for expressing an interferon alpha 2b (IFNa2b)/immunoglobulin G-4 (IgG4) Fc fusion protein, which has long-acting antiviral effects. Human IFNa2b and IgG4 Fc cDNAs were generated by molecular cloning and inserted into a baculovirus shuttle vector, which was then transposed into the DH10 Bac strain to form recombinant Bacmid-IFN/Fc. The Bacmid-IFN/Fc was transfected into High five insect cells, and expression of the IFN/Fc fusion protein was detected by Western blotting and its biological activity was assessed by the cytopathic effect inhibition method. The IFNa2b and IgG4 Fc cDNA fragments were successfully amplified by RT-PCR using human peripheral lymphocytes. After cloning into the baculovirus shuttle vector, pFastBac1, and transforming into DH10 Bac competent cells, screening identified positive clones carrying the recombinant Bacmid-IFN/Fc. A Bacmid-IFN/Fc clone was successfully transfected into the High five insect cells and packaged into the baculovirus for expression of the IFN/Fc fusion protein. Western blotting revealed that the fusion protein expression was specific, and yielded a protein of 45 kD in size. The in vitro antiviral activity of the IFN/Fc fusion protein was 580 IU/mL. A novel IFN/Fc fusion protein was successfully generated using a baculovirus insect cell system, which may prove useful for providing future experimental data for development of a new long-acting interferon to treat chronic viral hepatitis.

OBJECTIVEIn order to seek the functional evidence that there could be metastatsis suppressor gene for liver cancer on human chromosomes, the objective of this study is to establish a method of microcell mediated chromosome transfer (MMCT).

METHODSHuman chromosome 8 randomly marked with neo gene was introduced into highly metastatic rat liver cancer C5F cell line by treating the single human chromosome donor cells with sequential steps of micronucleation, enucleation and microcell fusion. Double selections of G418 and HAT were applied to screen positive microcell hybrids, which were cloned by single cell isolation. Microcell hybrid clones were confirmed by STS-PCR and WCP-FISH.

RESULTSMicrocell hybrids resistant to HAT and G418 were obtained, from which 15 clones were obtained by single-cell isolation cloning. STS-PCR and WCP-FISH proved that human chromosome 8 had been successfully introduced into rat liver cancer cell line C5F. The human chromosome 8 introduced into C5F was found to have random loss of chromosome fragments by STS-PCR and consistent recombination with rat chromosome by WCP-FISH.

CONCLUSIONThe successfulls introduction of human chromosome into highly metastatic rat liver cancer cell line has established the technical basis for functional localization of metastasis suppressor gene(s) for liver cancer on human chromosomes.
