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.

Objective:To summarize the clinical treatment experience of epidermal transfer factor(ETF) on oral lichen planus(OLP).Methods:66 OLP patients received ETF treatment were retrospectively investigated.Fully recovery,markedly effective,effective and ineffective were used as evaluation criteria.Results:The effective rate in test group and control group was 93.94% and 73.17% respectively(P

Objective To study the application value of direct digital X‐ray radiography system in the degenerative lumbar insta‐bility .Methods 100 patients with degenerative lumbar instability disease were collected in our hospital ,in which there were L4 ,L5 (80 cases) and L5 ,S1 (20 cases) with degenerative lumbar instability disease .Carestream DRX‐Evolution system was used ,which included conventional horizontal lumbar function photography (control group) and physiological load of lumbar function photography (observation group) .Changes of the displacement or the angle of the lumbar segment on two groups were measured ,and the statisti‐cal software was used to carry on the comparative analysis .Results In 100 patients ,the position and the physiological load position were showed on the sagittal position which were as following :For the lumbar segment of L4 and L5 ,flexion [position (4 .50 ± 0 .25) mm , load position (4 .78 ± 0 .30) mm] ,extension [position (4 .87 ± 0 .22) mm ,load position (5 .18 ± 0 .30) mm] ,and for the lumbar segment of L5 and S1 ,flexion [position (4 .64 ± 0 .24) mm ,load position (4 .91 ± 0 .24) mm] ,extension [position (4 .95 ± 0 .30) mm , load position (5 .30 ± 0 .29) mm];For the intervertebral angle degree of L4 and L5 ,flexion (position 10 .64° ± 0 .29° ,load position 12 .12°± 0 .57°) ,extension (position 11 .57°± 0 .24° ,load position 12 .61°± 0 .28°);For the intervertebral angle degree of L5 and S1 , flexion (position 11 .63° ± 0 .26° ,load position 12 .72° ± 0 .27°) ,extension (position 13 .55° ± 0 .30° ,load position 14 .58° ± 0 .33°) , respectively .The difference between two groups was statistically significant (P< 0 .05) .Conclusion Compared with traditional method ,DR lumbar physiological weight‐bearing functional can more accurately understand the lumbar instability degree ,grading and lumbar positive rate ,which provides the basis for clinical diagnosis and treatment plan .

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.

Objective To investigate the effect of T lymphocyte proliferation,Th1 and Th2 cytokines on T cells from systemic lupus erythematosus (SLE)patients by blocking 4-1BB/4-1BBL.Methods The proliferation of T cells from 30 SLE patients and 20 normal controls was detected by MTT and the levels of patients stimulated with anti-CD3 McAb were significantly higher than those of T cells without stimulation(P＜IFN-γand IL-4 in SLE were significantly higher than those of normal controls(P＜0.01).There were more ex-pression of IFN-γ and IL-4 in supernatant of T cells from SLE after stimulated with anti-CD3 McAb(P＜0.01).However,the production of IFN-γ and IL-4 was inhibited by anti-4-1BB McAb(P＜O.05),and especially the level of IL-4 was markedly decreased.Conclusion Blocking 4-1BB/4-IBBL can significantlv inhibit the abnormal activation of T cells and the secretion of Thl and Th2 cytokines of SLE.

Objective:To optimize and establish the experimental methods for the determination of 2,4-dihydroxybenzophenone (BP-1) in mouse brain. Methods:BP-1 was determined by high performance liquid chromatography (HPLC) and separated by Waters Symmetry? C18 (4. 6 mm × 250 mm, 5 μm) using isocratic elution, and the sample preparation conditions were optimized by orthogonal experiment design. The mobile phase was methanol-water (volume ratio 3∶1) containing 3% (volume fraction) ace-tic acid (pH 3. 40) at a flow rate of 1. 0 mL/min, and ultraviolet (UV) detection wavelength was set at 290 nm. Retention time was used for qualitative analysis and internal standard method for quantitative analysis. Results: Under the optimized experimental conditions, the calibration curve was linear with a correlation coefficient of 0. 999 8 over the concentration range of 0. 2-10. 0 mg/L. The recoveries of BP-1 were between 96. 8% and 104. 5%. The intra-day and inter-day precision of BP-1 were 3. 5% -5. 7% and 4. 5% -6. 4%, respectively. The extraction recoveries of BP-1 at three concentrations (0. 5, 2. 0, 8. 0 mg/L) in the mouse brain were 90. 5%, 89. 5%, and 97. 7%, and the matrix effect of BP-1 at these three concentrations were 102. 9%, 102. 7%, and 90. 9%, respectively. Conclusion:The method is simple, ac-curate, and suitable for determination of the contents of BP-1 in mouse brain.
