[Objective]To discuss the effects of DHS and compression screw application on femoral intertrochanteric fracture.[Method]Internal fixation was performed with DHS,DHS and compression screw,Ender nail and proximal femoral anatomical plate in 185 patients with femoral intertrochanteric fracture.The main outcome measures were operation duration,coxa adducta rates and postoperative Sanders scoring.[Result]All patients were followed up for 9-48 months.Operation duration was similar in the four groups.There were significant differences in coxa adducta rates and postoperative Sander's scores.According to the Sander's scores,the excellent to good rates in DHS and compression screw,DHS,Ender nail and proximal femoral anatomical plate groups were 94.6%,85.3%,75.4% and 80.6%,respectively.The coax adducta rates were 2.4%,9.5%,22.2% and 19.2%,respectively.[Conclusion]All the four kinds of internal fixation can be used for femoral intertrochanteric fracture,but DHS and compression screw is the best one for its good restoration of joint function and has no or little complication.

Objective To determine the level of defensins(HNP_(1-3))and interleukin-8(IL-8)in colon tissue of patients with ulcerative colitis(UC)and to explore the relationship between HNP_(1-3)and IL-8 and the severity of disease.Methods The level of HNP_(1-3)and IL-8 in colon mucosa of UC patients was detected by immunohistochemistry method.Results The levels of HNP_(1-3)and IL-8 in colon mucosa of UC patients were much higher than that of normal controls.The expression of HNP_(1-3)and IL 8 of UC patients was higher in involved mueosa than in corresponding normal mucosa.The expression of HNP_(1-3) and IL-8 was related to the extent of lesion and the degree of disease.The expression of HNP_(1-3)was significantly correlated with that of IL-8(r_s＝0.957,P＜0.01).Conclusions The induction of HNP_(1-3) and IL-8 was involved in process of inflammation and development of UC.Regulating mechanisms of HNP_(1-3)expression might be related with the induction of IL-8.

Objective To explore the relationship between brain development and early behavior development of infant rats. Methods Infant Spraque - Dawley(SD) rats were used respectively for testing their spontaneous behaviors, inhibitory escaping response and behavior development, and also determine their brain weight and content of Zinc in different part of the brain at age of 1 day, 11 days and 21 days. Results There was a positive correlation between brain development and early behavior development of SD rat, and the high content of zinc in hippocampus and cerebellum. Conclusion It is suggested that the high content of Zinc guarantee furnish security for the late behavior development of infant rat.

Objective: To evaluate the diagnosis value of percutaneous puncture biopsy technique under CT guiding in clinical pathological changes of breast. Methods:46 patients with breast lumps or nodules, including six cases of pleural disease, were carried out percutaneous puncture biopsy under CT guide, where a coaxial Angiotech 17G trocar together with BiopincelSG were used in the puncture process. Results: 44 cases of pathological findings were acquired and the diagnosis ratio was 93.4%, including 9 cases of squamous cell carcinoma, 24 cases of adenocarcinoma, 3 cases of small cell carcinoma, 1 case of metastatic tumor, 1 case of tuberculosis cases, 5 cases of inflammation and 1 case of normal reflexed pleura. 2 cases have no clear diagnosis. Conclusion: The percutaneous lung biopsy technique under CT guide has the merits of less diagnosis trauma, high diagnosis accuracy and high clinical application value.

To explore the relativity between alexithymia and cognitive function in somatoform disorder patients.A total of 40 patients aged 18-65 years fulfilling the criteria of ICD-10 for somatoform disorders were recruited as research group.And 40 normal healthy subjects were selected as control group.Toronto alexithymia scale-20 (TAS-20) was employed to examine the alexithymia.And cognitive abilities screening instrument (CASI) was used to measure their cognitive ability.The 9-factor scores and total score of CASI test in patients with somatoforill disorder were significantly lower than those in the normal controls (P ＜ 0.05 or ＜ 0.01).The 3-factor scores and total score of TAS-20 test in patients withsomatoforill disorder were significantly higher than those in the normal controls (P ＜ 0.05 or ＜ 0.01).In research group,CASI scores were negatively correlated with the TAS-20 scores (P ＜0.05 or 0.01).
