0.05). No death, pseudoarthrosis, or implantation failure occurred. Conclusions One-row portal pattern is suitable for patients with long-segment deformity and short anteroposterior thoracic diameter, while double-row portal pattern is suitable for patients with short-segment deformity and long anteroposterior thoracic diameter.

Objective To summarize our experiences on open heart surgery through the right subaxillary small incision. Methods Between March 2001 and June 2008,612 patients with congenital heart diseases were treated by open surgery trough a right subaxillary small incision via hypothermic cardiopulmonary bypass. The incision was made from the posterior axillary line at the axilla to the middle axillary line a the fifth intercostal space (4-8 cm in length),and then the intercostal muscle was cut at the inferior edge of the fourth rib for the entrance into the chest cavity. In this series,165 patients had ASD,403 had VSD,35 had ASD complicated with VSD,3 showed PECD,and 6 were found as PAPVC. Results The mean cardiopulmonary bypass time was (25.0?5.5) min,402 of the patients (65.6%) need no blood transfusion. The mean hospital stay was (6.0?4.5) d,no patient died in hospital. The 420 patients were followed up for 5 to 80 months (mean 47 months). During the period,cardiac ultrasonography showed good outcomes in the patients. No complications or death were detected. Conclusions Right subaxillary small incision is a safe and minimally invasive method for the treatment of ASD and VSD with quick recovery,less hemorrhage,shorter hospital stay,less complications,and satisfying cosmetic outcomes.

Objective To investigate the adverse reactions and survival rate of low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in treatment of elderly patients with primary hepatic carcinoma.Methods A total of 84 patients with primary liver cancer were enrolled and randomly divided into low dose group and high dose group.Patients received 40 mg/m2 and 80 mg/m2 of Oxaliplatin respectively,and adverse reactions and survival rate were compared between the two groups.Results Incidence of nausea and vomiting was obviously lower and the number of patients with pain scale above 6 was significantly smaller in low dose group than in high dose group,with statistically significant differences (11.9％ vs.21.4％ and 28.6％ vs.78.6％,x2 =9.910,20.056,both P ＜ 0.05).White blood cell count was significantly higher and alanine aminotransferase (ALT) was significantly lower in low dose group than in high dose group after treatment (t =13.447,6.774,both P＜0.05).1 year and 3 year survival rate was 69.05％ and 30.95％ in low dose group and 61.9％ and 21.43％ in high dose group,respectively,with no statistically significant difference (x2 =0.474 and 0.985,P=0.491 and 0.321).Conclusions Low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in the treatment of elderly patients with primary hepatocellular carcinoma is worth to be promoted in clinical application because it does not affect the patient survival rate and the toxic effects of the chemotherapy are very little.

[Objective] To evaluate the surgical techniques and its clinical results of CDH Legacy in the treatment of scoliosis.[Method]Nine patients(7 female and 2 male)with scoliosis instrumented with posterior CDH Legacy system were recruited for this retrospective study.The etiological classification of scoliosis were idiopathic for 7,congenital for 1,neurofibromatosis(NFl)for 1.The average age was 13.5 years(ranged 11～18 years).The average preoperative Cobb's angle was 54?(ranged 48?～68?).Seven AIS and one CS patients received one stage posterior CDH Legacy instrumentation;the NFl patients received one stage anterior epiphysiodesis and second stage posterior CDH Legacy instrumentation.[Result]There was no death,no infection and no neurological complication.No intra-operative fracture,no dura matter or pleuml laceration occurred.Superior Mesenteric Artery Syndrome occurred in one patients and recovered with conservative treatment.Posterior Cobb's angle averaged 20? with correction rate of 63%.The duration of follow-up averaged 23 months(ranged 20～30 months).Surgical time averaged 260 min(ranged 210～300 min)and mean EBL was 700 ml(300～1 000 ml).Bony fusions were achieved in all patients and no coronal or sagittal plane decompensation occurred.The loss of correction at last follow-up was 4? with 7.4% loss of correction rate.[Conclusion]The clinical results of CDH Legacy are as good as the other three generation implants,its advantage lies in lower profile,solid inter-locking,versatile implants and handy manipulation.

Objective To compare the clinical outcomes of selective thoracic spinal fusion in adolescent idiopathic scoliosis using either iliac bone or autologous rib combined with allografts. Methods A retrospective study was made in 84 cases of idiopathic thoracic scoliosis, who were operated on with posterior instrumentation of CD, CDH or TSRH from 1999 to 2000. These patients were divided into two groups. In Group A, 34 patients, who were 12 to 20 years with a mean age of 14.5 years with a mean Cobb angle 56?(range, 40? to 82?), received autologous iliac bone grafting, and no thoracoplasty were performed. In group B 50 patients, who were 13 to 19 years with a mean age of 15.4 years with a mean Cobb angle of 54? (range, 38? to 80?), had allograft bone grafting combined with the ribs from thoracoplasty. The patients were followed up for at least 2 years with an average of 3.4 years regarding the clinical and radiographic outcomes. Results For group A, an average of 73.2% correction rate was achieved, and average 10% loss of correction and 3% of pseudoarthrosis was recorded at 2 year follow-up. The incidence of donor site morbidity was 26%, which included deep infection, hematoma, delayed healing of incision and continuous pain. For group B, an average of correction rate was 70.4% with 9% average loss of correction and 2% of pseudoarthrosis at 2 year follow-up. The complications related to thoracoplasty consisted of intraoperative tear of parietal pleural, pneumothorax, effusive pleuritis, and chest pain. Conclusion The clinical outcomes are comparable between the group of iliac bone grafing and the group of rib grafing associated with allografts in terms of fusion rate and loss of correction. If chose appropriately, allografts plus autologous rib harvested from thoracoplasty will be a good alternative to iliac crest regarding its safety, efficacy and reliability.

Objective: To obtain the data of dental measurements in healthy Mongolia teenages.Methods: Normal dentognathic models were obtained by cephalometric roentgenography in 56 teenages (30 boys and 26 girls) aged 10～17 years. The width of the tooth crown, the size of the dental arch and dental base bone were measured with a vernier. The measurments were statistically analysed.Results: The tooth crown in boys was wider than that in girls( P 0.05). There was no significant difference in Bolton index and Point index between boys and girls.Conclusion: The dental measurments may be refrences for dental clinic and research.

Objective To observe the clinical effects of chemotherapy with intraperitoneal hyper-thermal perfusion for malignant ascites. Methods 40 patients with malignant ascites were randomly divided into two groups. In the treated group, 21 patients underwent intraperitoneal hyperthermal perfusion and local thermotherapy. 19 patients in the control group received commonly intraperitoneal perfusion. Results The CR, PR patients were 6,10 and 0,7 in the treated group and control group, respectively. The efficacy rate in the treated group was significantly higher than that in the control group. 2 patients oc-cured bellyache in the treated group and 1 patient in the control group, there was no statistically significant difference between the two groups. Conclusion Chemotherapy with intraperitoneal hyperthermal perfusion can significantly improve the therapeutic effects for malignant ascites, and has no more side effects.
