[Objective] To design anatomical steel plate for internal fixation of scapular neck fracmre.[Method]By observing the scapular structure and scapular fracture type,imaging a form of anatomical steel plate for internal fixation of scapular neck fracture,the needed relative measurement datum of scapula were obtained.Forty pairs of scapular spechnens of men and women were measured,relative datum were obtained.Based on the measurement,scapular neck fracture plate was designed.The steel plates were applied in patients with scapular neck fracture or scapular body fracture,patients were followed up after operations,the results were observed.[Result]Seven patients with scapular neck fracture or scapular body fracture were operated with the anatomical steel plates,the steel plates were obedient to the scapulas greatly,the fixations were strong,the operations were easy,the time of operations were short,seven patients were followed up for 12-18 months showing satisfactory results.[Conclusion]The design of anatomical scapular neck fracture steel plates is satisfactory,when using tile plate to fix scapular neck fracture.The fixation is strong,using the steel plate can be benificial to patient's early exercise.It has advantages of preventing complications,promoting fracture to heal,making the scapular operation easy,shortening the time of operation,lessening the blood in operation.This type of anatomical steel plate has the value to be popularized.

Objective To survey the status of nosocomial infection after total knee arthroplasty,analyze the risk factors of nosocomial infection and possible prevention measures.Methods Datas were collected retrospectively on 80pmients (80 knee joints) who were treated by total knee arthrophsly,the patients were divided into two groups,group A with nosocomial infection and group B without nosocomial infection.Statistic patient's age,basic diseases situation,preoperative hemoglobin content,serum albumin,operation time,blood transfusions,indwelling urethral catheter time,antibiotic treatment time of the two groups.And study the location,pathogenic bacteria and outcomes of the nosocomial infection patients.Results 10 patients occured nosocomial infection,the infected site in turn is urinary tract in 5 cases,respiratory tract 4 cases,skin infections in 1 case,the incidence of nosocomial infection is 12.5％.In noscomial infection group,patient's age,blood transfusions,operation time and postoperative indwelling urinary canal time significantly higher than no nosocomial infection group,anemia,hypoalbuminemia have relevance of nosocomial infection,there is no difference between the two groups in basic diseases situation.Conclusions The nosocomial infection after total knee arthroplasty caused by multiple factors,patient's age,hypoalbuminemia,anemia,operation time and indwelling urethral catheter time is closely related with nosocomial infection

[Objective]To investigate the treatment of thoracolumbar vertebral fracture without nerve symptoms.[Method]Thirty cases of thoracolumbar vertebrae fracture without nerve and spinal cord symptoms were treated with vertebra body restitution,pedicle screw fixation and posterolateral bone fusion.[Result]All the cases were followed up for 12-27 months,with an average of 15 months.There was no loosening and breaking of internal fixation.A great part of the height of the fractured vertebra body and the intervertebral body angle was restored(P

Objective To explore the association of COX-2 Gly587Arg polymorphism with the risk of primary liver cancer.Methods Two hundred and seventy patients with primary liver cancer and 540 health people were selected as our subjects.DNA were extracted from peripheral blood lymphocytes,and genotypes were measured by polymerase chain reaction-restriction fragment length polymorphism method.Odds ratios(OR) and 95％ confidence intervals(CI) were estimated by logistic regression.Results Two kinds of genotype (587Gly/ Gly and Gly/Arg) were found in all participants.No one carried 587Arg/Arg genotype.Among primary liver cancer patients,91.5％ (247/270,) 8.5％ (23/270) of individuals carried 587Gly/Arg and Gly/Arg genotype,which was significantly higher than that of controls (96.5％ (521/540,) 3.5％ (19/540)).Multivariate Logistic regression analysis showed that individual carried 587Gly/Arg genotype had an increased risk of developing primary liver cancer (OR =2.56,95％ CI =1.37-4.79,P =0.003) compared with 587Gly/Gly carriers.Conclusion COX-2 Gly587Arg polymorphism is a risk factor for primary liver cancer in Han.

Objective To evaluate the association of COX2 genetic variants with the risk of esophageal cancer and the interaction of COX2 genetic variants with Hp infection. Methods A total of 119 patients with esophageal cancer and 238 frequency-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Odds ratios (OR) and 95% confidence intervals ( CI) were estimated by logistic regression. Results Case-control analysis showed an increased risk of developing esophageal cancer for 1195 GA(OR =2.69,95% CI= 1. 46-5. 14) and 1195AA ( OR = 2. 30,95% CI = 1.23-4. 89) genotype carriers,respectively, compared with non 1195 GG carriers. When stratified by Hp status, the significantly increased risk of esophageal cancer was found among Hp carrier with OR (95%CI) =2.74 (1.35-5.96) ,but not among Hp non-carriers. Conclusion Genetic polymorphism in COX2 promoter region may play an important role in esophageal cancer by Hp infection.
