objective: To improve the repair technique of secondary nasal deformity following surgical treatment in the patients with bilateral cleft lip. Methods: 12 cases were treated with the operation technique: bilateral vermilion flaps were inserted into prolabial for the enlongation of upper lip and "V Y incision suture" principle was employed to repaire the nasal deformity. Results: Satisfactory results were achieved in all the 12 cases. Conclusion: The technique is feasible in the reconstruction of Cupid's bow, philtrum and correction of nasal and labia deformities.

Objective To explore a new method for reconstruction o f full-thickness defect of eyelid. Methods The composed skin flap which was lined the expanded forehead skin flap with oral mucosa were transferr ed to the defect of eyelid and then sutured anatomically to the eyelid skin. Fou r months later, the composed flap was divided to reconstruct upper and lower eye lids and put an artificial eye into it. Results The appearance and function of the eyelid was partly recovered. Conclusion The reconstruction of full-thickness eyelid defect with expanded and prefabricated skin flap with grafted mucosal liner is better and reliable.

Objective To investigate survivin as an anticancer therapeutic target by use of shepherdin [79-87],a novel peptide carrying the survivin sequence from Lys-79 through Leu-87,we constructed an recombinant vector containing fusion gene NT4-Ant-Shepherdin [79-87].Methods The gene of Ant-Shepherdin [79-87] was obtained by PCR and T-vector method.After cloned and digested with restricted enzyme,Ant-shepherdin [79-87] was inserted in PBV220NT4 vector.The recombinant vector was transformed into the competent cell,E.coli DH5?.The fusion gene of NT4-Ant-Shepherdin [79-87] was identified by agarose gel electrophoresis (AGE).Results DNA sequencing results verified that the sequence of Ant-Shepherdin [79-87] was consistent with what we had designed.After transformed E.coli DH5?,a fragment of 321 bp was confirmed.Conclusion The recombinant vector containing fusion gene NT4-Ant-Shepherdin [79-87] was successfully constructed in this experiment by molecular biology techniques,which provides the basis of further research of survivin for cancer gene therapy.

Objective To study a safe means of mandibular angle plasty of bone cutting and its clinical efficay.Methods Through grinding bone oblique trapezoidal incisure,mandibular angle wide deformity was then corrected according to the cutting trace on bone cutting method.Results Of 260 cases of torture beauty,185 cases were followed-up,in which 181 (97.84％) cases were satisfied with the results,and 1 case got satisfaction after facial liposuction; other 1 case did not accepted further treatment advice of bone cutting processing because her mandibular angle was too wide.Two cases of bone wax reaction occured and got satisfaction after treatment.Conclusions Mandibular angle plasty by combined grinding with cutting makes it easy for positioning and bone cutting; bone cutting arc becomes more fluent with good exposure of its posterior horn.It can prevent mandibular fracture induced by bone cutting that does not reach the designated position.Therefore,this procedure is relatively simple and safe.

Objective To investigate the possibility of performing epicanthoplasty with same stage small incision blepharoplasty. Methods At the same stage of designing small incision blepharo-plasty, modified "Z" plasty without flap transposition was designed. The upper lid incisive line of epi-canthoplasty was bided in the double eyelid fold, while the lower eyelid incision located at the edge of eyelid. Results A series of 56 patients were treated with this method. Satisfactory esthctical result of double eyelid fold and inner canthus shape was achieved. Conclusion This modified method including epicanthoplasty combined with same stage small incision blepharoplasty has the advantages of minimal scar formation, easy to design perform and in accordance with physiology.

Multidrug resistance (MDR) is one of the main causes leading to the failure in cancer treatment. Differential proteins between esophageal squamous cell carcinoma (ESCC) cell line EC9706 and its cisdiamminedichloroplatinum (CDDP)-resistant subline EC9706/CDDP revealed by quantitative analysis may provide deeper insights into the molecular mechanisms of MDR implicated in ESCC. EC9706/CDDP was generated by exposure of its parental sensitive EC9706 to a step-wise increase of CDDP concentration during EC9706 cultivation. The stable isotope labeling with amino acids in cell culture (SILAC) was used to label EC9706 and EC9706/CDDP with heavy and light medium, separately. Mixed peptides derived from EC9706 and EC9706/CDDP were analyzed by high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS/MS) and subsequently subjected to bioinformatics analysis to identify differential proteins between EC9706 and EC9706/CDDP. Compared to parental EC9706, EC9706/CDDP manifested phenotypes of slow proliferation, cell pleomorphology, atypia and increased resistant-index 3.23. Seventy-four differential proteins identified in the present study belongs to various families with multiple functions, such as cytoskeleton (20%), energy metabolism (11%), transcription regulation and DNA repair (11%), redox homeostasis (9.5%), protein biosynthesis and mRNA processing (12%), ribosome constituent (8.1%), molecular chaperone (8.1%), immunity/inflammation (5.4%), intracellular transport (5.4%) and nucleosome assembly (2.7%), which indicated that development of MDR is a complicated process involving dysregulation of multiple molecules and pathways. The data is of great value for in-depth elucidation of molecular mechanisms of the MDR implicated in ESCC and may represent potential molecular targets for future therapeutic development.

OBJECTIVETo investigate the technique for unilateral cleft lip nasal deformities.

METHODSThrough the traditional columella margin incision, the alar cartilage and the lateral nasal cartilage were exposed. After the mucosa between the two cartilages was divided, a mucosa-cartilage flap was developed and anchored, moving the lateral crus upwardly and medially, correcting the nasal deformity.

RESULTS52 cases of primary nasal deformities and 18 cases of secondary nasal deformities were corrected with this technique. Satisfactory results were achieved.

CONCLUSIONThis technique is recommendable, which is more likely to restore the physiological characters of the nose than the conventional technique.

Objective To compare the efficacy of different rehabilitation models on acalculia after acquired brain injury. Methods 113 cases were randomly assigned to 3 groups: control group(n=37), computer-assisted training group(n=38) and face-to-face training group(n=38). The control group just received cognitive dysfunction evaluation. The training groups received cognitive rehabilitation training 5 days a week and 30 minutes a day which sustained for 6 weeks. And 33 patients were selected to prolong for 12 weeks. They were evaluated with Revised EC301Calculation and Number Processing Battery in Chinese version (EC301-CR) at the beginning, the 6th week point and the 12th week point respectively. Results 6-week after treatment, The performance of both the computer-assisted training group and face-to-face training group significantly improved(P<0.001); It showed that computer-assisted group>face-to-face group>control group(P<0.001) both 6 weeks and 12 weeks latter. Significant negative correlation was found between age and performance of EC301-CR(P<0.05).Conclusion The effect of computer-assisted training on acalculia is superior to face-to-face training; The first 6 weeks of training is the best period for rehabilitation; The younger the patient is, the better results are.
