Objective To explore the PGI 2 and TXA 2 for lung cancer patients and ones with lung cancer metastasis,in onder to provide nomal index for diagnosis and differential diagnosis in lung cancer metastasis.Methods To test plasma PGI 2 and TXA 2 by means of RIA in all cases.One group of patients who received non operative treatment:Six cases of patients with distant metastasis;Eight cases with hilus of long metastasis;Seven cases without metastasis.The other group of patients who received radical operation;Six cases of patients with distant metastasis;Seven cases with hilus of lung metastasis;Six cases without metastasis.Result The PGI 2/TXA 2 ratio of the patient whether distant metastasis or hilus of lung metastasis was obviously lower than that of the patients without metastasis( P

Objective To investigate the diagnostic value of tissue polypeptide specific antigen (TPS),CYFRA21-1 and soluble tumor necrosis factor receptor (STNFR) in patients with lung cancer.Methods The serum levels of TPS,CYFRA21-1 and STNFR were determined by enzyme-linked immunosorbent assay (ELISA) in 72 patients with lung cancer,54 patients with benign diseases and 32 healthy adults.Results The levels of the 3 tumor markers in lung cancer group were significantly higher than those of the benign disease group and healthy control group,and the serum levels of this 3 tumor markers corresponding increased with the high TNM stage.The detectable rates of TPS (80.5%) and STNFR (81.9%) in serum of lung cancer were higher than CYFRA21-1(65.3%),and in TNM I group,the detectable rates of TPS (57.1%) and STNFR (57.2%) were higher than CYFRA21-1 (25.6%) too.Conclusion The TPS,CYFRA21-1 and STNFR can be used as a very useful and sensitive tumor marker in the diagnosis of lung cancer.The TPS and STNFR are better than CYFRA21-1 in clinical use.

Objective: To evaluate the cyclooxygenase-2 ( COX-2) expression at mRNA and protein levels , as well as its clinical significance, and to study the correlation of COX-2 with angiogenesis, apoptosis and estrogen or progestron receptors. Methods: Forty-one samples of normal endoraetrium tissues and 52 ones of endometrial carcinomas( EC) were collected,together with their corresponding clinical information. RT-PCR was adopted to determine the expression of COX-2 mRNA. Immunohistochemical staining was engaged to evaluate the protein expression of COX-2, VEGF, Bcl-2 and the MVD marked by CD105. And TUNEL was used to count the apoptosis cells. Results: (1) Significantly higher mRNA and protein levels of COX-2 were found in endometrial carcinomas than in normal endometrial tissues ( P＜0.001) . (2) At protein level ,COX-2 expression was related to the grade(P =0.020) , but had nothing to do with the stage, pathological type, depth of myometrium invasion and lymph node metastasis. Neither did the level of COX-2 mRNA with all the factors above. (3)The level of COX-2 mRAN had nothing to do with that of protein(P =0. 125, r =0. 222). (4) The higher the expression of COX-2 protein was, the higher that of VEGF,MVD or Bcl-2 was,and the lower the count of apoptosis cells was P＜0.05. (6)The upregulation of COX-2 protein had no correlation with ER-α and ER-β . But it had positive correlation with PRA and PRB,P was 0.031 and 0.007 .respectively. Conclusion: (1)The expression of COX-2 is significantly higher in EC than in normal endometrium tissue, not only at the mRNA level, but also at protein level. ( 2 ) At protein level, COX-2 expression is related to the grade, but has nothing to do with the stage, pathological type, depth of myometrium invasion and lymph node metastasis. Neither does the level of COX-2 mRNA with all the factors above. (3)The upregulation of COX-2 protein in EC correlates with the increase of VEGF protein and MVD. (4) The upregulation of COX-2 protein in EC correlates with the increase of Bcl-2 protein and the decrease of apoptosis cells. (5)The upregulation of COX-2 protein in EC has no significant correlation with ER expression, but has something to do with the increase of PRA and PRB.

Many studies have demonstrated the presence of increasing newly formed lymphatic vessels in tumour tissue, which is significantly correlated with the invasion of tumours,lymphatic metastasis, prognosis and so on. Re-cently,with the discovery of specific lymphatic endothelial cells markers and the development of novel experiment methods, turnout lymphangiogenesis become the focusing point for researchers. Here we will review what is known a-bout the reasons, molecular mechanisms and inhibitors of lymphangiogenesis in neoplasms.

MicroRNA-7(miR-7)was firstly found in Drosophila melanogaster,which participated in the formation of Drosophila wings,eggs and so on.In human being miR-7 is not only involved in cell prolifera-tion and differentiation,but also plays an important role in the development of tumor,especially in lung cancer. Most studies report that miR-7 is low expression in lung cancer with poor prognosis.Improving the expression of miR-7 can inhibit tumor growth.MiR-7 can regulate the expression of BCL-2,EGFR negatively,meanwhile it can regulate the sensitivity of tumor cells to radiotherapy chemotherapy and targeted therapy.Therefore,as a tumor suppressor,miR-7 is expected to become a new target for treatment of lung cancer.

Objective To investigate the clinical application value of Anti -CCP antibody ( CCP) levels in patients with in rheumatoid arthritis ( RA) .Methods 132 patients with rheumatoid arthritis , 42 patients of other categories of connective tissue dis-ease, 40 health cases were collected as the research object.The anti-CCP antibody titers were detected in sera of three patients, and the anti CCP antibody in rheumatoid arthritis in the diagnostic process was calculated .Anti -CCP antibody titers were detected in three group patients, and the specific of anti CCP antibody in diagnosis of rheumatoid arthritis was counted .Results Anti-CCP an-tibody has high specificity for the diagnosis of rheumatoid arthritis , and was correlated with clinical symptoms in patients with rheuma-toid arthritis.Combination detection of anti -CCP antibody and C reaction protein can improve the diagnostic specificity , and the difference was statistically significant (p<0.05).Conclusion The specificity of anti-CCP antibody in diagnosis of rheumatoid ar-thritis is higher and its specificity is higher than that of RF .The combined detection of anti -CCP antibody and RF both can improve the diagnostic specificity of rheumatoid arthritis , and anti-CCP antibodies are related with the degree of clinical symptoms .

Objective To explore the effect on the neural endocrine and gastro intestinal functions when using Chinese traditional medicine in the treatment after the gyno-pathy operation of the wond's complete cutting off. Methods To compare 86 postoperative cases of gyno-pathy (womb's complete cutting off) being treated partly with Chinese medicine wiht the same 75 cases treated during the same period without Chinese medicine in order to investigate the different effect on the recovery of their neural endocrine and gastric intestinal functions. HZ Results The result shows that the patients in the tested group can recouer quickly while the neural endocrine and the gastro intestinal functions of the opposite group cannot recouer or recover very slowly in a long time. Conclusion Traditional Chinese medicine is rather helpul for the recovery of thd postoperative gyno-pathy patients if it is correctly used .

Finite element is a common means to study pelvic biomechanics. This article introduces current methods to establish finite element model and application advances of the models in pelvis,and explores issues and future developing direction of pelvic finite element models.

Objective To explore the etiological spectrum of pancytopenia ,in order to improve the diagnostic accuracy . Methods Retrospectively analysed myelogram and clinical data of 196 cases of patients with pancytopenia syndrom .Results The dominant cause of pancytopenia syndrom in 196 cases of patients was hematological diseases (accounted for 68 .9% ) ,including acute leukemia (14 .8% ) ,myelodysplastic syndrome (12 .2% ) ,aplastic anemia(11 .2% ) and immune‐related pancytopenia(10 .2% );while non‐hematologic diseases accounted for 31 .1% ,including connective tissue diseases (10 .7% ) ,chronic liver disease(7 .2% ) and in‐fection(6 .2% ) .Conclusion Etiology of pancytopenia syndrom is complex ,which should be comprehensively analysed with closely contacting clinics ,in order to clarify the cause ,reduce misdiagnosis and missed diagnosis and improve the diagnostic accuracy .
