2.Esophageal stents for treatment of benign and malignant esophageal stenosis
Chinese Journal of Tissue Engineering Research 2011;15(16):3037-3040
BACKGROUND: Recent studies have demonstrated that esophageal stent is made of biodegradable materials and polymers,and satisfactory outcomes regarding its application in animal experiments have been made,but disputation exists. OBJECTIVE: To review the type,clinical application and related complications of esophageal stent. METHODS: Using esophageal stent,clinical application,complications in English and Chinese,manuscripts were retrieved by reading titles and abstracts. The manuscripts that are focused on the type,clinical application,and complications of esophageal stent as well as its application in malignant esophageal stenosis and the manuscripts that were recently published or in high-impact journals were selected. Finally,28 manuscripts were included. RESULTS AND CONCLUSIONS: Esophageal stent placement has become an important mean for esophageal carcinoma in patients who had no surgical conditions to relieve esophageal stenosis. With the development in technique,from initial membrane-free metallic stent,partial membrane-covered metallic stent to whole membrane-covered metallic stent,related esophageal diseases have been effectively solved,but the subsequent complications,such as gastrorrhagia and perforation,gastroesophageal reflux,and re-stenosis,have been not completely solved. Therefore,the therapeutic effects of different stents and the advantages and disadvantages of complications should be fully considered to reduce the complications to a largest extent and finally to improve patient's quality of life.

Microbial selective side-chain degradation of phytosterol,which can obtain the steroid medicine intermediate compounds-androst-4-ene-3,17-dione (4-AD) and androsta-1,4-diene-3,17-dione (ADD),has an important meaning to pharmacy. There is no systematic literature concerned in existence. Its mechnism,approaches,influencing factors and so on over these years were fully reviewed in the paper. The trend of development in the area is expanded.

Objective To explore the effects of estrogen and angiotensin Ⅱ receptor 1 inhibitor(saralasin)on cell proliferation,cell cycle and apoptosis in endometrial carcinoma cell line HEC-1A.Methods Immunocytochemical assay was applied to detect the expression of AT1-R,PI3K,p-Akt and ERK protein in HEC-1A cell.The effects of estrogen and saralasin on cell proliferation,cell cycle distribution and apoptosis of HEC-1A cell were detected by MTT assay and fluorescence activated cell sorting technique.The expression of ERK and p-Akt protein in HEC-1A cell treated with estrogen and saralasin were analyzed by Western blot.Results The expression of AT1-R,PI3K,pAkt,and ERK protein was found in HEC-1A cell.Estrogen stimulated the proliferation of HEC-1A cell,decreased G0~G1 phase proportion and increased S phase proportion significantly,minimized the number of apoptotic cells,and up-regulated the expression of ERK protein.Saralasin obviously inhibited the proliferation and induced apoptosis of estrogen induced HEC-1A cell,increased G0~G1 phase proportion and decreased S phase proportion,and down-regulated the expression of ERK protein.Conclusion Estrogen could promote the proliferation of HEC-1A cell through AT1-R.AT1-R inhibitor saralasin could inhibit the proliferation and induce the apoptosis of estrogen induced HEC-1A cell.The down-regulation of ERK protein expression by interrupting the mitogen-activated protein kinase(MAPK)signaling pathway might be involved in the possible mechanism.Thus saralasin could be a valid approach to treat ER-negative endometrial carcinoma.

Background and purpose:Epirubicin is one of the fi rst line chemotherapy drugs in the treatment of breast cancer, and liposome doxorubicin is a new antitumor drug that has been reported to have less cardiotoxicity and myelosuppression compared to free doxorubicin. Dentritic cells (DC) play important roles in tumor immunity. Our experiment investigated the impacts of epirubicin and liposome doxorubicin on different human breast cancer cell lines and dentritic cells, and evaluated their roles in the treatment of breast cancer. Methods:Human breast cancer cell lines, Bcap37 and MDA-MB-231, along with human dentritic cells isolated and induced into maturation, were cultured with epirubicin and liposome adriamycin at different concentrations (0, 0.25, 0.5, 1.0, 2.0, 4.0, 10.0 ?g/ml), respectively. The inhibitory effects were detected by MTT method after 24, 48, 72 h. Results:Epirubicin and liposome adriamycin could inhibit the proliferation of Bcap37 cells, MDA-MB-231 cells, and human dentritic cells. Liposome adriamycin exhibited a lighter inhibition on dentritic cells than on human breast cancer cell lines (Bcap37 and MDA- MB-231) (F=22.208, P

Objective To discuss the characteristics and management of pregnancy on cesarean section scar. Methods Five women with pregnancy on cesarean section scar were reviewed from Apr. 2000 to Mar. 2003. Results All of the five patients had cesarean section before and suffered from painless,irregular vaginal bleeding after 6~8 weeks of amenorrhea. The pregnancy could be misdiagnosed as invasive mole or cervical pregnancy. All had better outcome by uterine suction under ultrasound monitoring without massive bleeding or hysterectomy. Conclusions Women who had cesarean section before are in the risk of pregnancy on the old scar. Clear diagnosis should be made before any treatment. Ultrasound monitoring,local MTX injection and packing can be utilized to prevent perforation during suction. Patients should be monitored continuously after operation with serum hCG level and ultrasound. The principle prevention of pregnancy on cesarean section scar is to reduce the cesarean section rate and effective contraception.

Cancer Research and Clinic 2015;27(12):823-826
Objective To investigate the expression of HPV-DNA and p16,Ki-67 proteins in intraepithelial lesion of cervix (CIN) so as to provide the aluable evidence for the early clinical diagnosis and genetic therapy of the CIN.Methods Hybrid capture2 was used to detect HPV DNA in 35 cases of CIN Ⅰ,44 cases of CIN Ⅱ,and 20 cases of CIN Ⅲ.Immunohistochemical MaxVision was used to research the expression of p16 and Ki-67 protein in CIN Ⅰ,CIN Ⅱ and CIN Ⅲ.The results were analyzed with clinicopathological factors.Results Positive expression rates of HPV-DNA were 31.4 % (11/35),63.6 % (28/44),85.0 % (17/20) in CIN Ⅰ,CIN Ⅱ and CIN Ⅲ,respectively.The expression rates of p16 in the three groups were 65.7 % (23/35),97.7 % (43/44),100.0 % (20/20),there were statistically significant difference (x2 =21.30,P =0.00).The expression rates of Ki-67 in the three groups were 77.1% (27/35),79.5 % (35/44),95.0 % (19/20),there were no difference (x2 =3.00,P =0.22).Conclusions HPV infection is closely related to the occurrence and development of CIN.p16,Ki-67 can be used as objective marks in diagnosis of CIN.
