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 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.

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 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 .

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.
