Objective To analyze the prognostic factors associated with three-year survival outcome in patients with serous ovarian adenocarcinoma by classification tree.Methods Retrospectively we analyzed 81 cases with serous ovarian adenocarcinoma who had 3-year clinical outcomes and were hospitalized in People's Hospital from Jan 1991 to Dec 2003 by classification and regression trees(CART)software.Establish the classification tree.Results Among the factors that were associated with the 3-year survival rate,age was the most important factor,other factors in turn were International Federation of Gynecology and Obstetrics(FIGO)stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade.By substitution variable analysis,it was demonstrated that there was cross interaction between age and residual size as well as age and chemotherapy.Conclusion Age,FIGO stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade are important prognostic factors related with three-year survival probability of serous ovarian adenocarcinoma patients.

Objective To investigate the effect of administration intravenously of rosiglitazone (ROSI) on severe acute pancreatitis (SAP) in rats and its mechanisms. Method Fifty-four male Wistar rats were randomly divided into sham operation group (SO group), severe acute panereatitis model group (SAP group) and rosiglita-zone pretreatment group (ROSI group),18 rats in each group.SAP model was induced by retrograde inufsion of 5% sodium taurecholate into the biliopancreatic duct. The rats in SO group and SAP group were injected with 10% DMSO (0.2 ml/100 g) by femoral vein 30 minutes piror to the operation. In ROSI group,rosiglitazone partes ae-quales(6 mg/kg) was injected instead of 10% DMSO. Rats were killed at 3, 6 and 12 h after operation. Serum amylase level and myelopemxidase activity were detected. Pancreatic tissue samples were stained with hematoxylin and eosin for histopathological evaluation. Reverse transcription-polymerase chain reaction was used for detecting the levels ofTNF-α mRNA and ICAM-1 mRNA in pancreatic tissue. Results Amylase level, myeloperexidase ac-tivity, pathologic score and the expression of TNF-α and ICAM-1 mRNA were increased significantly in SAP group at each time point than those in SO group (P<0.05). Compared with SAP group, pretreatment with rosiglitazone reduced serum amylase level and pathologic score at time point of 6 h and 12 h (P<0.05), decreased myeloper-oxidase activity at 12 h (P<0.05), downregulatied the expression of TNF-α mRNA at all time pointy, (P<0.05),ICAM-1 mRNA at 6 h and 12h(P<0.05). Conclusions Rosightazone has the effect on pancreatitis in SAP through downregulating the expression of TNF-α mRNA and ICAM-1 mRNA.

Objective To find out the mechanism of strephenopodia and strephexopodia of children with spastic cerebral palsy by analyzing their gait character.MethodsForty children with spastic cerebral palsy and forty healthy children with normal walking ability were involved in this research.Footscan 7 gait analysis system was used to measure foot initial touchdown part,the ratio of different part touchdown phase to single supporting phase,the degree of strephenopodia and strephexopodia in different part.Two groups' characteristic parameters were analyzed by statistics method.ResultsSignificant differences were found in foot first touchdown part between two groups(P<0.05).The phenomenon that toes or metatarsus or whole foot first touch the earth was found in children with spastic cerebral palsy.The ratio of anterior foot and middle foot touchdown phase to single supporting phase were higher than normal children(P<0.05).In spastic cerebral palsy group the phenomenon of strephexopodia was more serious than strephenopodia during anterior foot touchdown phase.ConclusionLots of children with spastic cerebral palsy are suffering long-time compression pain and strephexopodia with anterior foot,active rectification must be performed during rehabilitation care.

OBJECTIVETo establish a finite element model of canine segmental mandibular reconstruction by partial-cortical-cutting distraction osteogenesis.

METHODSThe geometry model was established by Mimics software via reading the data of DICOM format from CT and was cut with Magics software. The finite element model was established and was analyzed by MARC software.

RESULTSA finite element model of canine segmental mandibular reconstruction by partial-cortical-cutting distraction osteogenesis was established. The model was composed of five parts. These five parts were felted via Magics software. The Von Mises stress of the joint region of slice and the slide segment were 34.60 MPa when the slide segment was retained 1.4 mm width during distraction osteogenesis with the force of 12 N.

CONCLUSIONThe biomechanics analysis can be complated through the finite element model of canine segmental mandibular reconstruction by distraction osteogenesis that retains lingual cortical bone.

Objective To discuss the clinical efficacy of internal fixation with miniature steel plate and kirschner pins in treatment for metacarpal neck fracture.Methods A total of 142 patients with cervix metacarpal fracture in our hospital from January 2015 to December 2016 were divided into the control group(n =71) and the observation group(n =71) randomly.The patients in control group were treated with internal fixation with kirschner pins,and the patients in observation group were treated by internal fixation with miniature steel plate.The operative time,postoperative healing time,postoperative pain,metacarpophalangeal joint function and complications were compared between the two groups.Results The operation time of observation group was (38.4 ± 3.8) minutes,the fracture healing time was (3.1 ± 1.4)weeks,the excellent and good rate of TAM was 97.2％ after operation,the excellent and good rate of FAFS was 98.6％ after operation,all these indexes were significantly better than those in the control group with statistical significance (P ＜ 0.05).Conclusion Internal fixation with miniature steel plate in the treatment of cervix metacarpal fracture has the advantages of exact clinical effect,short operative time,quick fracture healing and good recovery of joint function.

Objective To investigate the prevalence and associated risk factors of diabetes mellitus in populations of Hans and Kazaks in Xinjiang. Methods A total of 7 299 Hans and Kazaks adults from Shihezi, Xinyuan County of Yining city, and Shawan town of Tacheng City were surveyed. The data were collected according to questionnaire and physical examination and laboratory test. Results The prevalence rates of diabetes mellitus for male, female and all subjects were 8. 14% , 7. 77% , 7. 93% (Hans), and 7. 41% , 4. 90% , 5. 89% (Kazaks), respectively in Hans and Kazaks, Standardized rates were 6. 40% , 7. 06% , 6. 66% (Hans), and 5. 87% , 4. 60% , 5. 28% ( Kazaks), respectively . The prevalence rates of impaired fasting glucose( IFG) were 9. 54% , 8. 08% , 8. 70% ( Hans), and 12. 18% , 8. 62% , 10. 03% ( Kazaks), respectively. Standardized rates were 7. 04% , 7. 23% , 8. 54% ( Hans), and 10. 12% , 8. 09% , 9. 31% ( Kazaks), respectively. Old age, hypertension, dyslipidemia, overweight and obesity, and central obesity were risk factors for diabetes mellitus. Conclusion The prevalence rates of diabetes mellitus and IFG in Hans and Kazaks are higher than those in ethnic minorities in other region. Primary or secondary prevention should be implemented in time.
