Objective To explore the clinical effect of anterior combined with posterior fixation and vertebra reconstruction for unstable lumbar burst fracture via small incision alone posterior median line.Methods This study was based on 40 patients suffering from unstable lumbar burst fracture,who underwent anterior combined with posterior fixation and vertebra reconstruction.All the patients were followed up for 1～2 years.The shape and the function of spinal column were estimated in preoperative stage,postoperative stage and the duration of following.The data in the formal 3 stages were compared.Results Between the preoperative and postoperative data,there were statistically significant differences in the Cobb's angle,angle of kyphosis,anterior height of the fracture vertebral body,sagittal index and JOA scores(t=34.085,31.604,27.988,23.798,31.834,all P＜0.05).But no similar result was detected between the postoperative data and the data during the following(P＞0.05).Conclusion Anterior combined with posterior fixation and vertebra reconstruction via small incision had a significant effect in unstable lumbar burst fracture,and it was worthy of further study and clinical popularization.

The clinical data of 22 cases with gastrointestinal stromal tumors were retrospectively analized.The main clinical manifestations were gastrointestinal bleeding (14/22),abdominal discomfort (5/22) and abdominal lump (3/22),stomach was the most common site of the tumor (14/22).All 22 cases underwent surgical treatment and pathological examination confirmed that 12 cases were benign.Immunohistochemical results showed that 68% cases were negative in solubility acid protein-100 (S-100),and the positive rates of tyrosine-protein kinase acceptor 117 (CD117),hemopoietic stem cell antigen 34 (CD34) and negative rate of smooth muscle actin (SMA) were all 73%.Eighteen cases were followed up for 1-5 years after operation,among them 3 died.The survival was closely related to the size,the pathological characteristics and the recurrance of the tumor as demonstrated by multivariate Cox regression analysis.Since gastrointestinal stromal tumor has no specific clinical manifestations,preoperative diagnosis is difficulty,so surgical resection and subsequent pathological examination is used for confirmation of diagnosis,as well as treatment of the disease.

Most studies show that the blood transfusion can promote patients tumor recurrence, and lower their 5-year survival rate. Even patients in the early phase, a small amount of blood transfusion has significant effect. Blood transfusion causing tumor recurrence may be due to that blood transfusion recipients suppressed immune function, resulting in rapid growth of residual tumor cells. In this paper, blood transfusion for patients with tumors will be discassed. induding the benefit and danger of blood transfusion autotransfusion and blood substitutes for patients with tumors ,and development of transfusion medicine in our country.

ObjectiveTo compare the clinical efficacy of surgical treatment and non-surgical treatment of humerus surgical neck fracture for elderly patients. Methods106 elderly patients who were diagnosed of fracture of surgical neck of humerus were selacted as the research object, of which 56 patients underwent surgical treatment using locking compression plate ( Operation group ), 50 patients underwent non - surgical treatment using skin traction smoothing method( Control group) ,all the patients were followed up for 6 to 10 months,the clinical efficacy and complications were eorpared. ResultsOperation group, good rate of 83.9％, significantly higher than contra group,good rate of 60.0％ ,the difference was statistically significant ( x2 = 7.61, P ＜ 0.01 ). Operation group, no postoperative complications,5 cases of non- surgical complications, two groups had significant differences in complications (x2 =3.86, P ＜ 0.05 ). ConclusionSurgical treatment of humeral surgical neck fractures in elderly rehabilitation had better efficacy, fewer complications.

Objective To verify that traditional Chinese medicines have certain price advantages compared with western medicines,and to estimate the rational increase in the compensation proportion of traditional Chinese medicine in the new rural cooperative medical system.Methods Using stratified sampling survey and literature review,the average outpatient and hospitalization expenses in the treatment of common diseases in rural areas were calculated and compared among traditional Chinese medicine,western medicine,and integrated traditional and western medicine.Results For average outpatient and hospitalization expenses,traditional Chinese medicine was lower than western medicine,integrated traditional and western medicine was lower than western medicine.and traditional Chinese medicine was lower than integrated traditional and western medicine.For hospitalization expense,traditional Chinese medicine had a 25.2%lower expense compared with western medicine.The ratios of expenses were statistically calculated,and the mathematical model for the compensation proportions of traditional Chinese medicine and western medicine in the new rural cooperative medical system was put forward.Conclusions In the implementation scheme of new rural cooperative medical system,the compensation proportion of traditional Chinese medicine in outpatient and hospitalization expenses should be increased by 25%and 33%respectively compared with western medicine.
