Objective] To study the determination of telomerase and CEA in differentiating benign and malignant pleural effusions. [Methods] Telomeric repeat amplification ELISA method(TRAP- PCR-ELISA) and enzyme immunoassay(EIA) were measured in 40 patients with malignant pleural effusion and 38 cases of benign pleural effusion telomeres activity and CEA levels. [Results] The telomerase activity in pleural effusions and CEA positive rate in malignant pleural effusion group were 80.0%(32/40) and 85%(34/40), benign pleural effusion group was 7.9%(3/40) and 0%(0/38), malignant pleural effusion of telomerase and CEA-positive rate was significantly higher than benign pleural effusion group, the difference was significant(χ2=40.96,57.26, P<0.001).Determination of telomerase activity in malignant pleural effusion diagnostic sensitivity and specificity of CEA rather, the difference was not statistical y significant(χ2=0.35, P>0.05). Two combined detection of tumor markers in terms of a positive diagnosis of malignant pleural effusion as the standard, the combined detection sensitivity was 97.5%(39/40), significantly higher than the telomerase and CEA single detection sensitivity 80% and 85%, the differences were statistical y significant(χ2=6.13,3.91,P<0.01). [Conclusion] Detection of the TA and CEA in pleural effusion is of a definite value in differentiating benign from malignant pleural effusion, and the detection of TA is more sensitive and specific than detection of CEA. Combining detection of both markers may raise the accuracy of the diagnosis.

Traditional Chinese medicine owns the duality of commodity property and quasi-public goods in the process of production and circulation. According to the duality of traditional Chinese medicine, giving full play to government function is the key to guaranteeing and promoting the quality and security control in the dryness process of traditional Chinese medicine. Government functions mainly focus on improving the quality and security control ability of production operators and stimulating quality and security control motive of producers. This article began with the duality of traditional Chinese medicine, expounded the government functions in the dryness process and quality control of traditional Chinese medicine from macroscopic and micro levels, and proposed the measures of improving dryness process based on government functions.

ObjectiveTo study the clinical effect of locking compression plate fixation in treatment of the elders with unstable fractures of the distal radius. Methods17 cases with unstable distal radius fractures were treated by volar locking compression plate. The function of the carpal joints and the bone healing conditions were evaluated after operations. ResultsAll cases were followed-up for 7 to 16 months ( mean 12. 6 months). Union was obtained in all the patients after 11.4 weeks. The clinical outcomes were evaluated according to modified X-rays and wrist assessment. 12 cases were graded as excellent and 4 as good. 1 case were graded as poor. The overall satisfactory rate was 94. 1％. ConclusionThe unstable distal radial fractures could be effectively treated with open reduction and LCP fixation through volar approach.

Objective:To observe the expression of B7-H4 in experimental autoimmune myocarditis (EAM).Methods:BALB/c mice were randomly divided into 2 groups:the control group and the experimental group.The mice of experimental group were injected with myosin to establish EAM models , while the mice of control group were injected with complete Freund 's adjuvant and normal saline.All the mice were killed separately at the 14th,21st,30th and 45th day for lymphocyte proliferation assay ,hematoxylin-eosin staining,immunohistochemical staining and real-time PCR.Results:The inflammation infiltration of heart was most serious at the 14th and 21st day,then it was gradually relieved with time;the results of lymphocyte proliferation assay and real-time PCR were similar to that of the inflammation infiltration of heart ,which were in high level at the 14th and 21st day,and they were both higher than that of the control group ( P<0.05 );B7-H4 protein were only detected in the experimental group ,and it was constantly expressed during the whole experiment on the endothelium of heart with myocarditis.Conclusion:B7-H4 participates in the progress of EAM ,and it may be a new way of studying the mechanism of myocarditis.

Objective To investigate the expression of tumor-associated carbohydrate antigen sTn in breast neoplasm,and analyzed the association between the expression of sTn and size of tumor,age,menopause,axillary lymph node metastasis,clinical stage,pathologic grade and the level of estrogen receptor in breast carcinoma.Methods The monoclonal antibody TKH-2 was used to detect the immunohistochemical expression of sTn in 46 cases of breast carcinoma,4 breast adenoma and 2 gynecomastia.The level of estrogen receptor was detected by S-P method in 46 breast carcinoma.Results Immunohistochemical expression of sTn was not detected in breast adenoma and gynecomastia.The expression of sTn was found in 28 of 46 breast carcinoma(60.9%).The expression of sTn was significantly associated with axillary lymph node metastasis(P0.05).In 46 breast carcinoma,the positive quantity of estrogen receptor was 25(54.3%).Conclusion STn immunostaining appears to be a poor prognostic factor in patients with breast carcinoma.It is more useful in detecting the expression of sTn together with the level of estrogen receptor in breast carcinoma to investigate the prognosis of the patients.

ObjectiveTo evaluate the value of application of spiral CT with 3D reconstructure on diagnosis and treatment of tibial plateau fractures.Methods15 cases of tibial fractures treated with x-ray and 16-slices spiral CT,3 D images were made,fractures were classified and evaluated with 3D images and treated with correct treatment.ResultsAll of the 15 patients got correct diagnosis by 16-slices spiral CT with 3D reconstructure,1 failed by x-ray.10 fractures were operated under 3D reconstructure guide and operation proved fractures revealed by 3D reconstructure finally.ConclusionSpiral CT with 3D reconstructure could offer more accurate location and classification of tibial plateau fractures,and it had obvious advantage on demonstration of spatial relationship,and it also could provide better planning and management for the tibial plateau fractures.
