Despite multimodel chemotherapy after successful surgical cytoreduction for ovarian cancer,disease recurrence continues to be problematic.Therefore,exploring new treatment strategy has already become urgent matter of the moment. Biological targeted therapies have been studied to overcome chemotherapy resistance.The most promising one at this time is bevacizumab.Results from phase Ⅱ and phase Ⅲ trials were excited.Deeper understanding of biologic pathway in ovarian cancer,and more biologic targets undergoing clinical trial will develop a new world for the treatment of ovarian cancer.

Objective To investigate the relationship between the expression of T lymphoma invasion and (metastasis) inducing factor 1 (Tiam1), ras-related C3 botulinum toxin substrate 1 (Rac1) with the invasion and metastasis of gastric cancer. Methods The expressions of Tiam1 and Rac1 proteins in 60 cases of (gastric) cancer and paracarcioma gastric mucosa tissues were detected using Strept Avidin-Biotin Complex(SABC) immunohistochemical method,and the correlation between the expression of Tiam1, Rac1 and (clinicopathological) parameters of gastric cancer were analysed. Results (1)There was negative staining of Tiam1 protein in paracarcioma gastric mucosa tissues, while positive staining was detected in gastric cancer (tissues)(78.33%)(P 0.05). (4) The expression of Rac1 in patients with positive staining of Tiam1 was significantlyhigher than that in patients with negative staining(P

The maxillary sinus is the largest paranasal sinuses. Foreign bodies of nosal sinus can caused by car accidents, firearm attacks, or iatrogeniccause. We reported two rare cases of foreign body of pulp needle and loach. The clinical manifestations might include facial numbness, facial paresthesia, swelling, nasal congestion, facial pain, eye discomfort, limited mouth opening and relapse and etc. Both CT scan and the medical history were helpful in diagnosis. Functional endoscopic surgery would be the first choice of treatment.

Objective To study the inhibition effect of leech extract on HepG2 cells. Methods Human hepatocellular cancer cell line HepG2 were treated with different concentrations of leech extracts which were extracted by method of freeze-thawing with liquid nitrogen and contrasted with that by method of water extracting and ethanol precipitating. The inhibition effects and cell morphous were examined by MTT assay and Acridine orange (AO) fluorescent staining method respectively. Result The 6～15 mg/mL drug concentrations of leech extract by method of freeze-thawing with liquid nitrogen had an obvious inhibition on proliferation of HepG2 cells in a dose-dependent manner, and the effect was better than that by method of water extracting and ethanol precipitating (P

Objective:Measured the soluble forms of intercellular adhesive molecule 1 (sICAM 1), soluble vascular cell adhesion molecule ( sVCAM 1) and interleukin 1(IL 1),tumor necrosis factor(TNF), interferon ?(IFN ?),study the role of sICAM 1 and sVCAM 1 in rheumatoid arthritis(RA).Methods:A sandwich ELISA technique was used to measure the serums levels of sICAM 1, sVCAM 1 ,IL 1,TNF,IFN ? in 30 patients with active RA and 30 normal control subjects.Results:The levels of sICAM 1 and sVCAM 1 in patients with RA were significantly higher than that in control subjects(P

Purpose:To evaluate the efficacy and toxicities of gemcitabine plus cisplatin for patients with relapsed ovarian cancer. Methods:Twenty-eight patients with recurrent ovarian carcinoma received gemcitabine (1000 mg/m~(2)) plus cisplatin (35 mg/m~(2)) on days 1 and 8 of each 21-day cycle. Of 28 patients, sixteen who relapsed within six months of previously platinum-based regimen were platinum-resistant and the other twelve were platinum-sensitive. Results:Of 28 patients, there were 5 (17.9%) complete and 12 (42.9%) partial responses, for an overall response rate of 60.7% (95%CI: 41.7%–79.6%). The median time to progression for objective responders was 5.5 months with a range of 2.5 to 20 months. Median overall survival for all 28 patients was 12.5 months. Among 16 platinum-resistant patients, a 56.3% response rate occurred. The median survival time was 10.5 months. Among 12 platinum-sensitive patients, a 66.7% response rate occurred. The median survival time was 14.5 months. There were leukopenia grade Ⅲ in 35.7%, grade Ⅳ in 17.9%; thrombocytopenia grade Ⅲ in 28.6 %, grade Ⅳ in 14.3% of patients. Conclusions:Cisplatin plus gemcitabine is active in patients with relapsed ovarian cancer. The adverse effects are tolerable. Hematologic toxicities are manageable with dose modifications.

Objective To study whether omeprazole induces gastric epithelial cells apoptosis and analyse the possible mechanism. Methods The cell cycle and apoptosis ratio of SGC 7901 cell line were determined by flow cytometry in the presence of omeprazole, meanwhile, TUNEL positive cells from gastric mucosa were counted after incubated with omeprazole for 72 hours. Expression of p53、 GADD 45 、 p15,16,18,19 and bcl 2 were stained by immunohistochemical assay and ATPase activity was tested. Results significant alteration with decreasing percentage of G 1 phase and increasing percentage of G 2 phase of SGC 7901 cell line could be detected after incubating 24 hours with omeprazole at double clinical doses . An apoptosis peak appeared in flow cytometry after incubating 72 hours with omeprazole. However, no genetic products such as p53, GADD 45 , p15,16,18,19 and bcl 2 were seen. Concentrations of ATPase were markedly increased from 0.326 0.387 before incubated with omeprazole to 0.054 0.103 after incubated with omeprazole. TUNEL positive reaction cell counts in fresh mucosa was also increased after incubated with omeprazole for 72 hours( P

Background and purpose:As a regulatory factor of cytoskeletal structure,a close correlation existed between Tiam 1(T lymphoma invasion and metastasis inducing factor 1) and the invasion and metastasis of gastroenteric tumor.We aimed to observe the effects of Tiam 1 antisense oligodeoxynucleotides(Tiam 1 ASODN) transfection on the invasive and migratory potentials of gastric cancer cells in vitro and vivo.Methods:The higher invasive and migratory subgroup(MH) were separated from human gastric cancer cell line MKN-45(M0) by laminin adhesion method in vitro.Tiam 1 ASODN was transfected into MH cells with liposome,and the expression of Tiam 1 mRNA and protein was determined by RT-PCR and ELISA separately.Changes in the invasive and migratory potentials of MH cells in vitro and vivo after transfected with ASODN were observed by Boyden chamber test and inoculation into nude mice respectively.Results:The expression of Tiam 1 mRNA and protein in MH cells after transfected with 0.43 ?mol/L ASODN(0.162?0.018,0.982?0.119) was significantly lower than that of either Liposome-transfected cells(0.789?0.054,1.237?0.108),sense oligodeoxynucleotides(SODN)-Liposome-transfected cells(0.754?0.039,1.234?0.103) or No-transfected cells(0.801?0.065,1.290?0.182)(P

Objective To detect the gene expression difference between gastric cancer tissue and lymph node metastasis,screen different express genes,and study its mechanism of metastasis and the relationship with biological behavior.Methods Using U133plus 2.0 gene chip technology,we detected the gene expression difference between gastric cancer tissue and epithelial cells of lymph node metastasis in five patients,and screened out the differentially expressed gene Twist-l.In vitro,the cell proliferation and apoptosis level were measured by using gene over-expression and gene knockout.Metastasis ability of carcinoma cells was detected by cell scratch assay.The expression changes of epithelial-mesenchymal transition (EMT)-associated protein (E-cadherin,Vimentin) in Twist-1 overexpression and gene knockout cells were determined by Western blot.Finally,we detected the expression of Twist-1 in gastric cancer tissue,and its correlation with TNM stage was analyzed.Results The expression of Twist-1 was higher in epithelial cells than in gastric cancer tissue (12.12±3.21 vs.2.07±0.71,P＜0.01).There was no correlation of the expression of Twist-1 with cell proliferation(absorbance of cell proliferation:negtive control 0.84±0.16,null vector control 0.74 ±0.06 and Twist-1 expression cell 0.71 ± 0.07) and apoptosis [cell apoptosis rate:negtive control (2.05±0.08)％,null vector control (4.31±0.07)％ and Twist-1 expression (3.95±0.09)％],but cell migration ability enhanced.In Twist-1 over-expression group,the level of E-cadherin was decreased,while vimentin increased.Conclusions Twist-1 gene changes might be correlated with the metastasis of gastric cancer by the way of EMT.
