The patients were divided into low-molecular-weight heparin anticoagulation group (22 cases) and blank control group (21 cases) according to the random number table method. The blood routine, coagulation quadruple, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity before and after catheterization were compared between the two groups. \u0000 \u0000 \u0000Results \u0000Of the 43 patients, 5 cases (11.62%) occurred PICC-DVT within 1 month after PICC, including 2 cases (9.09%) in the low-molecular-weight heparin anticoagulation group, and 3 cases (14.29%) in the blank control group, the difference between the two groups was not statistically significant (P = 0.664). No pulmonary embolism occurred in all patients with PICC-DVT. One case in the blank control group developed PICC-DVT and catheter-associated staphylococcus aureus infection, the patient was extubated after anti-infection and thrombolytic therapy, the other patients with PICC-DVT were not extubated, and the thrombus was dissolved after anticoagulant therapy. There were no significant differences in the white blood cell count, platelet count, prothrombin time, activated partial thromboplastin time, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity between the low-molecular-weight heparin anticoagulation group and blank control group (all P > 0.05). The anticoagulant index (protein C, protein S or antithrombin Ⅲ activity) was decreased in 5 patients with PICC-DVT, and in 38 non-thrombotic patients, the anticoagulant index was reduced in 16 patients (42.11%), the difference was statistically significant (P = 0.021). \u0000 \u0000 \u0000Conclusions \u0000The incidence of protein C, protein S or antithrombin Ⅲ activity reduction in hematological malignancies patients with PICC-DVT is higher than that in non-thrombotic patients. Low-molecular-weight heparin anticoagulant therapy can not reduce the occurrence of PICC-DVT within 1 month after PICC in patients with hematological malignancies, but the treatment is safe and has no relevant bleeding event. \u0000 \u0000 \u0000Key words: \u0000Hematologic neoplasms; Peripherally inserted central catheter; Antithrombin Ⅲ; Protein C; Protein S; Catheter-related thrombus","PeriodicalId":9505,"journal":{"name":"Cancer Research and Clinic","volume":"31 1","pages":"679-683"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43543766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the postoperative pathological results, these patients were divided into the ovarian epithelial cancer group (494 cases) and benign ovarian disease group (462 cases). The serum expressions of HE4 and CA125 in the two groups were detected by enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay. The diagnostic value of detection of HE4 and CA125 alone or in combination for ovarian epithelial cancer was analyzed. \u0000 \u0000 \u0000Results \u0000The median levels (P 25 - P 75) of serum CA125 and HE4 in ovarian epithelial cancer group were 273.34 U/ml (39.34 U/ml, 709.74 U/ml) and 199.08 pmol/L (75.81 pmol/L, 449.20 pmol/L), which were higher than those in ovarian benign disease group [16.30 U/ml (6.30 U/ml, 53.60 U/ml) and 39.54 pmol/L (29.57 pmol/L, 53.80 pmol/L)] (both P < 0.05). There was a positive correlation between serum CA125 and HE4 levels in ovarian epithelial cancer group (r = 0.481, P < 0.01). Serum CA125 and HE4 levels in patients with stage Ⅲ and Ⅳ were higher than those in patients with stage Ⅰ and Ⅱ (both P < 0.05), and serum CA125 and HE4 levels in patients with poor differentiation were higher than those in patients with moderate differentiation (P < 0.05). Compared with CA125, the specificity and positive predictive value of serum HE4 for the diagnosis of ovarian epithelial cancer were higher (both P < 0.01). Compared with HE4 alone, the sensitivity of CA125 combined with HE4 increased (P = 0.004) and the specificity decreased (P = 0.044). When both CA125 and HE4 were positive for positive results, compared with HE4 alone, the specificity and positive predictive value increased (both P < 0.01), but the sensitivity decreased (both P < 0.01). In patients with CA125+ HE4-, the sensitivity and specificity decreased, while in CA125- HE4+ patients, the specificity was elevated, but the difference was not statistically significant (P = 0.892). When one of CA125 and HE4 was positive for positive results, the sensitivity and negative predictive value increased (both P < 0.01), but the specificity and positive predictive value decreased (both P < 0.01). The area under the curve of serum CA125 and HE4 combined detection was 0.911, indicating its clinical diagnostic value was better than that of the two alone. \u0000 \u0000 \u0000Conclusions \u0000In the diagnosis of epithelial ovarian cancer, the specificity of serum HE4 is higher than that of CA125, but the sensitivity is lower than that of CA125. The combined detection of HE4 and CA125 is more conducive to improve the diagnostic accuracy of ovarian epithelial cancer. \u0000 \u0000 \u0000Key words: \u0000Ovarian neoplasms; Carbohydrate antigen 125; Human epididymis protein 4; Diagnosis","PeriodicalId":9505,"journal":{"name":"Cancer Research and Clinic","volume":"31 1","pages":"653-657"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42922138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the mRNA expressions of CD97 human epidermal growth factor (EGF) (1, 2, 5), CD97EGF (1, 2, 3, 5) and CD97EGF (1, 2, 3, 4, 5) in colon cancer tissues, adjacent tissues, normal colon tissues, SW480 cells and SW620 cells. The relationship between the mRNA expression of CD97EGF (1, 2, 5) and the clinicopathological factors was analyzed. \u0000 \u0000 \u0000Results \u0000Compared with those low expressions in adjacent tissues and normal tissues, the mRNA expressions of CD97 isoforms CD97EGF (1, 2, 5), CD97EGF (1, 2, 3, 5) and CD97EGF (1, 2, 3, 4, 5) in cancer tissues were highest, and the differences were statistically significant (0.71±0.20 vs. 0.40±0.09 vs. 0.35±0.07, F = 107.642, P < 0.01; 0.45±0.11 vs. 0.26±0.05 vs. 0.27±0.06, F = 94.231, P < 0.01; 0.41±0.10 vs. 0.21±0.05 vs. 0.19±0.03, F = 165.672, P < 0.01). In addition, the mRNA expression of CD97EGF (1, 2, 5) in colon cancer patients was associated with tumor infiltration depth (T1-T2 and T3-T4), clinical stages (Ⅰ-Ⅱ and Ⅲ-Ⅳ), and the differences were statistically significant (t = -2.582, P = 0.013; t = -5.062, P < 0.01). The mRNA expression of CD97EGF (1, 2, 5) in SW620 cells was higher than that in SW480 cells. \u0000 \u0000 \u0000Conclusions \u0000CD97 isoforms are highly expressed in colon cancer tissues, and CD97EGF (1, 2, 5) may play an important role in the development and invasion of colon cancer. The CD97 isoforms may be new markers in the treatment of colon cancer. \u0000 \u0000 \u0000Key words: \u0000Colonic neoplasms; Isoform, CD97; Reverse transcriptase polymerase chain reaction; Pathology, clinical","PeriodicalId":9505,"journal":{"name":"Cancer Research and Clinic","volume":"31 1","pages":"662-665"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47079573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
