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

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.

Objective This article is to discuss the best injection time after alcohol disinfection during the prophylactic immunization,provide theoretical support to guarantee the effect of disinfection in practical work,also guarantee the effect of vaccination especially for the vaccination of attenuated live vaccine at the same time reduce the side effect in disinfection.Methods Choosing the vaccination objects as experimental subject,each period contained 40 people,who were named as group A,B,C,D,E,with a total of 200 people.Using sterile cotton swab sampling and agar plate cultivation method,counting bacteria.Selecting vaccine either in liquid or in lyophilized form,counting the time of picking up the vaccine,dissolving it,suction and preparing the injector.Results After alcohol disinfection,there was 1 person and 1 colony growth in group A within 25 s.There were 1 person and 4 colonies growth in group B within 40 s.There were 3 persons and 3 to 12 colonies growth in group C within 60 s,there were 5 persons and 2 to 8 colonies growth in group D within 80 s,there were 8 persons and 3 to 13 colonies growth in group E within 100 s.The difference between group A,B,C and D was not statistically significant.All four groups mentioned above had significant difference compared with group E.The time of whole process for vaccine either in liquid or in lyophilized form was 1.05 min and 29 s.Conclusions During vaccine injection,especially injectable attenuated live vaccine,it is safe time to finish injecting within 25 to 45 seconds.In the operating process of vaccine inoculation,the freeting and drying dosage-form vaccine,the operation sequence must be set as dissolve the seedlings,disinfection,checkup information again and injections.For water dosage-form vaccine,the operation sequence is to disinfection,pulling out seedlings,checkup information again and injections.
