Objective To evaluate the compliance effect of secondary prevention on high risk patients of gastric cancer and to investigate their knowledge,attitudes,and practice about gastric cancer.Methods 206 high risk patients of gastric carcinoma cancer were investigated with questionnaires.Results of all cases,54 patients were compliant,69 patients semi-compliant,and 83 patients were not compliant in monitoring cohort.The results showed distribution of the compliant patients was significantly different with their gender,occupation and family income per person,and not significant with their education background.Conclusion The compliance and KAP of the patients on high risk for gastric cancer aren't satisfied,which needed to be enhanced in the future.

Objective To investigate the expression of dual-specificity phosphatase 6 (DUSP6) in ovarian epithelial serous tumors and the relationship between DUSP6 expression and the clinicopathological parameters of ovarian serous cystoadenocarcinoma.Methods The expression of DUSP6 was analyzed by immunohistochemistry.Relationships between the expression of DUSP6 and the clinicopathological parameters of ovarian serous cystadenocarcinoma were also analyzed.Results DUSP6 expression was lower in patients with ovarian serous cystadenocarcinoma group with serum CA125 levels of less than or equal to 900 U/mL than in patients with serum CA125 levels of greater than 900 U/mL (P ＜ 0.05) and in patients whose ascites volume was less than or equal to 500 mL than in patients whose ascites volume was greater than 500 mL (P ＜ 0.05).Conclusion DUSP6 is related to the occurrence of ovarian serous carcinoma and is potentially related to the peritoneal metastasis of ovarian serous carcinoma.DUSP6 may be a new molecule for the early diagnosis and therapy of ovarian serous carcinoma and peritoneal metastasis.

Objective: To explore the normal range of plasma VWF levels of healthy Chinese and to analyze the influencing factors to VWF level. Methods: To detect the levels of von Willebrand factor antigen (VWF∶Ag) , von Willebrand factor ristocetin cofactor activity (VWF∶Rco) , von Willebrand factor collagen binding activity (VWF∶CB) , and the factor Ⅷ coagulation activity (FⅧ∶C) by using fully automatic and standardized testing instruments and matching reagent in 70 healthy Chinese. The effects of age, ABO blood type, gender and region were also analyzed. Meanwhile, 8 standard plasma samples (2 normal subjects, 6 cases of type 2 VWD) confirmed by NIBSC were tested for VWF values. Results: ① In 70 cases of healthy Chinese, the mean value of plasma VWF∶Ag, VWF∶Rco and VWF∶CB were (95.4±44.9) %, (105.9±35.4) % and (89.8±28.4) %, respectively; the ratio of VWF∶Rco/VWF∶Ag and VWF∶CB/VWF∶Ag was 1.18±0.25 and 1.03±0.29, respectively. ②There was no statistical significance in plasma VWF values between the age ≥30 years and <30 years group (P>0.05) . ③The VWF∶Rco, VWF∶CB of type O blood group were lower than that of non-O group (t=2.074, P=0.042; t=3.949, P=0.001) , but there was no statistical significance in VWF∶Ag, VWF∶Rco/VWF∶Ag, VWF∶CB/VWF∶Ag between the two groups (P>0.05) . ④There was no significant difference in VWF values between male and female groups (P>0.05) . ⑤The VWF∶Ag, VWF∶CB of the northern population (North area of Huaihe River) group were higher than that of southern population (Suzhou area) group (t=4.525, P=0.001; t=3.214, P=0.002) , but VWF∶Rco/VWF∶Ag, VWF∶CB/VWF∶Ag were lower than that of southern population group (t=6.373, P=0.001; t=2.902, P=0.005) , and there was no significant difference in VWF∶Rco between the two groups (t=1.598, P=0.115) . ⑥The VWF values of 8 standard plasma samples were in accordance with the known diagnosis. Conclusions A more integrate plasma VWF levels of healthy Chinese people were obtained for the first time by using fully automatic and standardized testing instruments. It was also found that ABO blood group and region had a significant impact on the level of VWF, while the age and gender had no significant effect.

Objective: To assess the significance of DDAVP use in the diagnosis and treatment of VWD. Methods: An analysis of 15 VWD cases who referred to Hematology Division of First affiliated Hospital of Soochow University and treated with DDAVP from March 2016 to August 2018 was conducted. Efficacy and treatment response of DDAVP were monitored by observations of changes in factor Ⅷ procoagulant (FⅧ∶C) and von Willebrand Factor (VWF) related indicators before and 2 h after DDAVP injection. Results: Of 15 cases with VWD, 7 males and 8 females with a median age of 23 (6-46) years, 7 of 9 type I VWD patients achieved complete response (CR) , 1 type 2A VWD case CR, 5 type 3 VWD ones no response (NR) . The VWF multimer analysis in 5 patients combined with other plasma VWF values were in accordance with the known diagnosis. Conclusions DDAVP was effective in most type 1 patients, and ineffective in some type 2 and almost all type 3 cases. It was helpful for diagnosis and subsequent treatment planning.

OBJECTIVETo investigate the feature of underlying disorders, clinical symptoms, diagnosis and treatment strategies of patients with acquired hemophilia(AH).

METHODSThe clinical data and laboratory tests results of 22 patients with AH from March 2010 to June 2014 were retrospectively analyzed.

RESULTSA total of 22 patients with AH were enrolled in our study, including 20 patients diagnosed as acquired hemophilia A (AHA) and 2 as acquired hemophilia B (AHB). Among the AHA patients, there were 10 males and 10 females with the median age of 37.5 (range, 2-95) years old. The median activity of FVIII (FVIII:C) of the 20 AHA patients was 1.9% (0.5%-39.0%). Soft tissue hematoma (80.0%) and subcutaneous bleeding (75.0%) were the most common clinical symptoms. Two male children were diagnosed as AHB (age 1 and 3 years old, respectively) with mild bleeding symptoms, and the activities of FIX (FIX:C) were 5.0% and 16.0%, respectively. In addition, an underlying disorder was found in 7 patients (31.8%). In laboratory testing, all patients had prolonged APTT, normal PT, decreased FVIII:C or FIX:C, positive antibody screening test or antibody titer (2-32 BU), and negative for lupus anticoagulant and anticardiolipin antibody. Nineteen out of 20 patients were treated with blood products to stop acute bleeding episodes. Corticosteroid alone was applied to 7 patients, corticosteroid combined with other immunosuppressive agents to 11 patients, rituximab to 3 patients. Nineteen patients responded well to hemostatic treatment, except 1 patient who died of fatal bleeding. The FVIII:C of 8 patients increased to a normal level with the median time of 42.5(21-145) days. After treatment, the activity of FIX:C of the 2 AHB patients achieved 35% and 24% in 48 and 60 days, respectively.

CONCLUSIONAcquired hemophilia is not an uncommon disease in clinical practices, which can occur in people of all ages. AH is a bleeding disorder with heterogeneous characteristics. Compared with adult, the clinical symptoms of children patients were mild, which lead to underdiagnosis.
