Objective To investigate the clinicopathological features of thymic neuroendocrine carcinoma and its differential diagnosis. Methods Clinicopathologic analysis and immunohistochemical staining were performed in 5 cases of TNC. Results For 5 cases TNC, 3 cases occurred in men, 2 cases occurred in women. The average age was 46.8 years. They were with chest symptoms before operation. 3 cases were Ⅱ and 2 cases were Ⅲ by clinic stages. Grossly , the tumors were gray in color with areas of hemorrhage and necrosis. Histopathology of well differentiated 2 cases and poorly differentiated 3 cases. Immunohistochemically, the tumor cells were positive for CK, NSE, SyN and CgA. 3 cases were positive for PCNA, Ki67, p53. Conclusions TNC has a pleomorphic appearance of histological features with well, moderate and poorly-differentiated areas. Immunohistochemical staining is helpful in the differential diagnosis of TNC from other tumors derived from the thymus. Neither grading as neuroendocrine carcinomas nor any individual histologic parameter showed a significant association with prognosis. Initial aggressive treatment, including complete surgical excision and adjuvant radiotherapy, appears to offer the best hope for prolonged survival. Adjuvant chemotherapy also should be considered, because the incidence of distant relapse is high.

ObjectiveTo analyze the causes of discomfort occurring in the interventional treatment of diabetic foot, to discuss the individualized nursing measures for improving the patient's comfort and cooperation,and for increasing the successful rate of the interventional procedure.MethodsThe control group included 9 patients who received conventional nursing care.The study group had 13 patients who accepted individualized nursing care and nursing intervention, which was designed according to every patient's individual conditions. ResultsIn the control group, one patient could not endure the surgery to the end because of the long operating time. Another two patients had to take examinations repeatedly because the imaging quality was very poor,which was caused by the body movement due to uncomfortable mechanical stimulation.Urinary retention occurred in one patient.The mean operative time of the control group was 2.8 hour per surgery.The average dosage of contrast medium used was 150 -300 ml per procedure.All the subjects in the study group completed the surgery successfully,the mean operative time was 2.2 hour per surgery and the average dosage of contrast medium used was 100 -200 ml per procedure.Conclusion During the perioperative period of interventional treatment for diabetic foot, the effective individualized nursing care and nursing intervention,the measures to improve patient's comfort and the cooperation,etc. can certainly increase the successful rate,saving the operating time and reducing the contrast dosage.

Endotoxins are lipopolysaccharides ( LPS) , major component of out wall in Gram-negative bacteria. Often they are considered as "prime criminals" of triggering systemic inflaming reaction such as sepsis, bacteremia and so on. It was found in recent years that bactericidal/permeability-increasing protein, a 55kDa member of lipid-related protein family, was a kind of natural molecule of anti-infection and it has special endotoxin-neutralising activity and antibacterial activity. Comprehensive phase II/III clinical trials demonstrated the feasibility and safety of recombinant BPI. So pharmaceutical corporations are attracted to try to apply it to therapy.

Objective To explore biomechanical properties and clinical results of a new type of dynamic Hoffmann external fixator(NDHEF)for tibial shaft fractures.Methods Fifteen specimens of adult tibia were randomly divided into three groups and osteotomized obliquely in the mid part of the tibia.These specimens were fixed with NDHEF,improved Hoffmann external fixator(IHEF)and maltifunctional external fixator(MEF)re- spectively.The axial compression,bending,torsion and stress shielding tests were performed on the specimens in each group for biomechanical comparison.From 1995 to 2004,40 cases of open tibiofihular fractures were treated with NDHEF and 88 cases with IHEF and their clinical results were analyzed and compared.Results The biomechanical tests showed that the compressive rigidity,bending rigidity and torsion rigidity of NDHEF were similar to those of IHEF(P>0.05)but significantly stronger than those of MEF(P<0.05).The stress shielding of NDHEF was obviously weaker than that of other external fixators(P<0.05).All the 128 cases were followed up for 12 to 36 months(average,16.8 months).The mean substantial bone healing time for NDHEF treatment was 22.3 weeks and that for IHEF was 26.8 weeks.The difference was significant(P<0.05).The rates of delayed union and malunion were all 7.5% for NDHEF,but 15.9% and 4.5% respectively for IHEF.The difference was insignificant (P>0.05).Conclusions The biomechanical performance of NDHEF is superior to that of IHEF,for it can diminish the stress shielding and accelerate bone healing.It is a good external fixator for tibial fractures.

Objective patients with pSS and 30 cases of healthv contrels.The streptavidin immunohistochemical staining was performed to detect the expression and distribution of MMP-9 and CD147 in labial salivary glands.Quantitative analysis was performed by image analysis software-image plus 5.0 at the site of positive expression of MMP-9 and CD147.The correlation between their expression and the infiltrating lymphocyte foci per 4 mm2 of labial gland was analyzed by SPSS software as well as the correlation between the expression of MMP-9 and CD 147 in the salivary glands of patients with pSS.Results MMP-9 was hiKhly expressed in labial salivary glands from 52 patients with pSS and 30 healthy controls,but the expression of MMP-9 in pSS was stronger compared with that of healthy controls(P<0.01).There was a significant positive correlation between lymphocyte foci score and up-regulated expression of MMP-9 in labial salivary glands from 52 patients with pSS(P<0.01).CD147 was highly expressed in labial salivary glands from 52 patients with pSS and 23 healthy controls,but over-expression of CD147 in PSS was more Drominent compared with that of controls(P<0.01).There was a significant positive correlation between lymphocyte foci score and up-regulated expression of CD147 in labial salivary glands from 52 patients with pSS(P<0.01).The expression of MMP-9 and CDl47 was detected in ductal and acinar epithelial cells,lymphocyte foci in pSS.There was linear correlation between the expression of MMP-9 and CDl47 in the salivary glands of patients with pSS(P<0.01).Conclusion The results of this study suggest that the abnormal expression of MMP-9 and CD 147 is involved in the pathogenesis of pSS and play a crucial role.The interaction of MMP-9 and CD147 may be one of theimportant mechanisms leading to labial salivary glands destruction found in pSS.
