1.The molecular mechanisms of lymphangiogenesis in neoplasms
International Journal of Surgery 2008;35(9):639-642
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.
2.Expression and function of cyclooxygenase-2 in endometrial carcinoma
Journal of Peking University(Health Sciences) 2009;41(6):657-663
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.
3.Treament for the Postopertive Gyno-pathy of a Complete Cutting off of the Womb with Traditional Chinese Medicine
Journal of Chinese Physician 2002;0(S1):-
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 .
4.Perinatal care of 5 pregnant patients with hypoparathyroidism
Modern Clinical Nursing 2017;16(3):12-15
Objective To explore the experience of nursing the patients with hypoparathyroidism.Methods Five pregnant patients with hypoparathyroidism hospitalized in our hospital during January 2009 to December 2015 were included in the study.The nursing intervention included performance of health care during pregnancy,childbirth and postpartum nursing.Results The thyroid function of the 5 patients became normal after medication and delicate care.All underwent cesarean resection and all the infants were normal in terms of thyroid function.Conclusions Pregnancy combined with hypoparathyroidism is of high risk and harmful for mothers and neonates.So they should be under management of high risk pregnancy.The prenatal,intrapartum and postpartum nursing measures should be implemented to ensure the safety of delivery.

6.Role of human leukocyte antigen-G small interference RNA in a choriocarcinoma cell line
Chinese Journal of Obstetrics and Gynecology 2001;0(08):-
Objective To study the role of human leukocyte antigen-G (HLA-G) in the carcinogenesis and development of choriocarcinoma. Methods We designed and synthesized a double strand small interference RNA (siRNA) of HLA-G, then transfected it into a HLA-G overexpressed choriocarcinoma cell line, JEG-3 by lipofectine; HLA-G mRNA level was detected by real time RT-PCR; HLA-G protein level was detected by western blot. The living cells of JEG-3 were counted under microscope after transfection by siRNA. Results Double strand siRNA of HLA-G effectively downregulated the mRNA level and the protein level of HLA-G. The mRNA levels by Ct value at different concentration (1.0, 2.5, 5.0 ?g/L) were 20.67?0.02, 21.37?0.03,21.43?0.02, respectively. They were significantly different compared with the control groups which were 20.33?0.01, 20.37?0.02,20.40?0.03, respectively ( P

8.Detecting the levels of serum TPS、CYFRA21-1 and STNFR in patients with lung cancer and its clinical value.
Chinese Journal of Practical Internal Medicine 2001;0(06):-
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.
