Objective To find the source of CA 125 in serum and the values of the expression of CA125 in serum, ascites and tissue in patients with epithelial ovarian cancer. Methods Detected the expression of CA125 in the primary lesions of epithelial ovarian cancer and the metastasis in abdominopelvic cavity (peritoneal and omental metastatic lesions) by S-P immunohistochemical methods. Compared the expression of CA 125 in tuberculose focus and acute inflammation focus in abdominopelvic cavity and detected CA125 in serum and ascites by ELISA. Results The levels of CA125 in serum of the patients with epithelial ovarian cancer [(523.66±158.02)kU/L],benign epithelial ovarian tumor [(138.11±26.52)kU/L] and tuberculosis of abdominopelvie cavity [(486.56±147.10)kU/L] were higher than that with the normal ovary [(17.48±3.37)kU/L], and there were significant differences (P<0.05).The levels of CA125 in serum of the patients with epithelial ovarian cancer and tuberculosis of abdominopelvic cavity were significantly higher than that with benign epithelial ovarian tumor, and there were significant differenees (P<0.01). The levels of CA125 in ascites of the patients with epithelial ovarian cancer [(996.85±337.87)kU/L] and tuberculosis of abdominopelvic cavity [(596.78±197.10)kU/L] were higher than that with benign epithelial ovarian tumor [(179.48±63.08)kU/L] and normal ovary [(177.70±51.72)kU/L], and there were significant differences (P<0.01).The level of CA125 in ascites of the patients with epithelial ovarian cancer was higher than that with tuberculosis of abdominopelvic cavity, and there was significant difference (P<0.01). By correlation analysis, the relationship of the level of CA 125 in serum and in ascites of the patients with epithelial ovarian cancer was positive correlation(r=0.687). Conclusion Besides the original and metastatie lesions (greater omenta and peritoneum) of epithelial ovarian cancer can express CA 125, the second Maller canal, for example the peritoneum mesothelial cell can be stimulated to express CA125 by ascites, which results in the increase of CA125 in serum.

Objective To evaluate the effects of Rebamipide,Omeprazol and their combination in treatment of gastric ulcer.Methods Forty gastric ulcer models were induced by acetic acid and randomly divided into 4 groups with 10 in each.The rats in control,Rebamipide,Omeprazol and combination groups were received saline (3 ml/d),Rebamipide (60 mg/kg),Omeprazol (10 mg/kg) as well as Rebamipide combined with Omeprazol for 7 days,respectively.After sacrifice,size of the ulcer and focal layer structures were measured in vitro by using miniature probe ultrasonography(MPS),mucosal sections were stained with H-E for histological examination,levels of interleukin-8/ prostaglandin E2 (PGE2) and methylenedioxyamphet amine (MDA) were evaluated by ELISA and TBA,respectively. Results ① Miniprobe ultrasonography revealed that comparing to control group[(22.3 ± 1.8)mm2], the maximal length of ulcer in Rebamipide [(9.2 ± 1.0) mm2 ],Omeprazol [(9.8 ± 1.3) mm2] and combination [(4.8 ± 1.2 )mm2 ] groups were significantly reduced ( P<0.05 ).② In vitro,MPS examination revealed that layer echo structure of gastric wall was partially rebuilt in three medication groups,③ Histopathologically,comparing to control group,ulcer range and inflammatory infiltration in all medication groups were less important.④ The mucosal level of IL-8 in control group [(1387.8 ± 132.6)pg/ml] was higher than that in Rebamipide group[(970.0 ± 91.6) pg/ml],Omeprazol group [(1102.2±76.9)pg/ml] and combination group[(934.4 ± 110.2) pg/ml] (P<0.05).⑤ The mucosal level of MDA was (9.4±1.4)nmol/ml and (8.5 ± 4.8)nmol/ml in Omeprazol and Rebamipide groups, respectively,which was higher than that in combination group[(4.6±1.4)nmol/ml-] and lower than that in control group[(13.0±2.6)nmol/ml].⑥ The PGE2 level was significantly increased in Omeprazol, Rebamipide and combination groups [(96.9 ± 7.0) pg/ml,( 103.5 ± 12.5 ) pg/ml,and(235.5 ± 26.0) pg/ m,respeetively] compared to control group[(55.0±22.5)pg/ml,P<0.05)].Conclusions Rebamipide, Omeprazol and combination regimen may improve quality of ulcerative healing by increasing level of PGE2 and decreasing levels of IL-8 and MDA in gastric mucosa,and this will result in potentially reducing the rate of ulcer recurrence.Combination regimen shows more anti-ulcer effect comparing to monotherapy.

Objective To elucidate whether down-regulation of homo sapiens eukaryotic translation elongation factor 1 alpha 2 (EEF1A2) expression induces apoptosis in pancreatic cancer cells and its possible mechanisms. Methods Two siRNAs targeting human EEF1A2 were synthesized and the siRNA/liposome complexes were transfected into the pancreatic cancer cell line BxPC-3. RTPCR and Western blot were used to analyze the change of EEF1A2 expression and the apoptosis rate of BxPC-3 cells was studied using Annexin-V/PI assay. To identify the mechanisms involved, the apoptosis associated proteins such as caspase-3, caspase-8, caspase-9, PARP, cytochrome C and Bid were detected by Western blotting. Results Both EEF1A2-targeting siRNAs reduced the EEF1A2expression, and the No. 2 siRNA inhibited EEF1A2 expression to less than 25 % in mRNA and protein levels. Down-regulation of EEF1A2 expression in BxPC-3 cells enhanced cell apoptosis (15.28% ±3.65%) at a greater level than negative siRNA-expressing cells (10. 11% ± 3. 05%) or mock cells (9.41 % ±4.14 %). Furthermore, reduction of EEF1A2 activated the pro-caspase-8, pro-caspase-3,pro-caspase-9,PARP and Bid to their active forms, and increased the expression of cytochrome C.Conclusions These data suggest that EEF1A2 down-regulation could significantly induce apoptosis of pancreatic cancer cell line BxPC-3, which is likely mediated by the death receptor and mitochondrial apoptotic pathways.

Background and purpose: At present, the treatment of elderly patients with ovarian cancer, espe-cially advanced ovarian cancer, tends to be conservative, and elderly patients often can not receive standard treatment. There are few treatment experiences and research data. This study aimed to investigate the treatment outcome, survival and prognostic factors of elderly patients with advanced epithelial ovarian cancer. Methods: This study retrospectively analyzed the clinical data for women older than 65 years diagnosed with stage Ⅲ and Ⅳ epithelial ovarian cancer between Apr. 2008 to Dec. 2012 in Chongqing Cancer Hospital. Results: Of the 181 women who met study criteria, 8.8% received no treatment, 12.7% underwent surgery alone, 15.5% received chemotherapy alone, 33.2% underwent non-standard treatment, 29.8% underwent standard treatment. Baseline comparison of different treatment methods showed that the proportion of patients with cardiovascular and cerebrovascular diseases was lower in the standard treatment group. After Correcting the effect of cardio-cerebrovascular diseases, the median survival time of standard treatment (48 months) and the median survival time of non-standard treatment (47 months) were significantly longer than that of the other treatment groups (P<0.001). The median survival time of chemotherapy alone (26 months) was significantly longer than that of the surgery alone and untreated group (P<0.001), while the median survival time of surgery alone was similar to untreated group (9 months vs 8 months, P=0.269). Multivariate analysis using Cox model showed that treatment, residual lesion size, cardio-cerebrovascular diseases significantly impacted on survival time. Conclusion: Standard treatment was still the key factor for the best survival of elderly women with advanced ovarian cancer. When this is not offered or possible, chemother-apy alone offers better survival than surgery alone. However, surgery alone does not improve prognosis.

Objective To investigate the risk factors,clinical characteristics and outcomes in patients with acute myocardial infarction and history of stroke. Methods A total of 771 patients with acute myocardial infarction diagnosed and admitted to Xuanwu Hospital,Capital Medical University from January 2005 to March 2012 were analyzed retrospectively. They were divided into either a stroke group (n=387)or a control group (n=384)according to whether they had previous ischemic stroke or not. The risk factors for cardiovascular disease,clinical characteristics of the disease,and clinical outcomes of the patients in both groups were compared through the case control analysis. The endpoint events observed were acute ischemic stroke,cerebral hemorrhage,and cause of death during hospitalization. Results (1)The median age of the patients in both stroke and control groups was 71 (37-91 )and 62 (29-90 )years respectively. The female patients in the stroke group were more than those in the control group (n=125 vs. n=91). The incidence of complicated with hypertension (72. 9%[n=282]and 47. 6%[n=183]) and type 2 diabetes mellitus (39. 0%[n=151]and 20. 8%[n=80]respectively)were high. There was significant difference between the two groups (P<0. 01). (2)The time from the onset to admission in patients of the stroke group was longer than that in patients of the control group (median 11 h vs. 4 h). The incidence of non-ST segment elevation myocardial infarction (16. 0%[n = 62 ]and 1. 8%[n = 7 ] respectively)was higher. The incidences of complicated with gastric stress ulcer (7. 0%[n =27 ]and 2. 1%[n=8]respectively),atrial fibrillation (10. 6%[n=41]and 3. 9%[n=15]respectively),and acute pulmonary edema-cardiac function Killip class≥Ⅱ(51. 9%[n =201 ]and 37. 8%[n =145 ] respectively)were more higher. The findings of coronary angiography in patients of the stroke group were that the incidence of left main coronary artery or 3 -branch lesion higher than that of the control group (52. 9%[126/238]and 32. 4%[97/299]respectively). There was significant difference (P <0. 05). (3)The incidence of new stroke in patients of the stroke group (5. 7%[n =22 ]and 1. 8%[n =7 ] respectively)and in hospital mortality (13. 7%[n=53]and 7. 6%[n=29]respectively)were higher than those of the control group. There were significant differences (P<0. 01). Conclusion The age of the patients with acute myocardial infarction with previous identified history of stroke is older. The incidence of female patients is higher than that of the non-stroke patients,and most of them have risk factors that complicated with hypertension and diabetes mellitus. These patients often have the complications with peptic ulcer disease and heart failure,and their coronary angiography often show multi-branch lesions,and they are more prone to ischemic cardio-cerebrovascular events during the hospitalization.
