Objective To investigate the effect of hemostatic drug on coagulation status after operation of bladder tumor.Methods Eighty-two bladder tumor patients in hospital for treatment were selected,and were randomly divided into observation group and control group with 41 patients in each.The patients in observation group were treated with hemostatic drug after operation,and the patients in control group were treated without hemostatic drug.The coagulation status between two groups were compared after operation.Results The index of preoperative coagulation status between two groups had no significant difference (P＞ 0.05).Compared with the preoperative,the activated partial thromboplastin time(APTT) and prothrombin time (PT) in two groups were prolonged on postoperative 1,2 d,plasminogen activator inhibitor (PAI)-1,tissue plasminogen activator (t-PA),D-Dimer (D-D) were increased,platelet (PLT) was decreased,thrombin time(TT) was shortened,there were significant differences (P ＜ 0.05).On postoperative 1,2 d,Tr in observation group was shorter than that in control group[(14.36 ± 0.17) s vs.(15.42 ± 0.18) s,(14.36 ± 0.28) s vs.(15.29 ± 0.27) s],PAI-1,t-PA,D-D were significantly higher than those in control group [(98.19±2.32) μg/Lvs.(82.19±2.38) μg/L,(84.52±2.25) μg/Lvs.(72.94±2.26) μg/L,(27.06 ± 1.69) μg/L vs.(21.63 ± 1.16) μg/L,(27.28 ± 1.37) μg/L vs.(21.69 ± 1.19) μg/L,(7.06 ±0.08) μg/L vs.(1.89 ± 0.28) μg/L,(12.83 ± 1.05) μg/L vs.(1.96 ± 0.18) μg/L],there were significant differences (P＜0.05).No significant difference was found in PLT,APTT,PT between two groups (P＞0.05).The incidence of deep vein thrombosis (DVT) in observation group and control group was 7.32％(3/41),2.44％ (1/41),which had no significant difference (P ＞ 0.05).Conclusions The application of hemostatic drug can aggravate hypercoagulability of patients with bladder tumor after operation.Therefore,it should be carefully applied preventive hemostatic drug.

Objective To investigate the risk factors for complications after tension-free repair in patients with inguinal hernia.Methods A retrospective analysis was made on clinical data of 503 patients with inguinal hernia after tension-free repair.The gender,adhesion,BMI index,the size of hernia sac,hernia type,patch type,degree of adhesion of the hernia ring and the mode of anesthesia were analyzed,and the risk factors were summarized.Results 47 cases occurred complications in 503 patients,the incidence rate was 9.34%.Chi square test showed that the degree of adhesion of the hernia ring and BMI index might be the influence factors of complications after operation,the differences were statistically significant(x2=11.495,8.944,all P<0.05).The degree of adhesion of the hernia ring and BMI index were taken into logistic regression analysis,and found that the degree of adhesion of the hernia ring and BMI index were the independent risk factors,the differences were statistically significant(OR=2.034,2.439,all P<0.05).Conclusion The incidence rate of complications after tension-free repair in patients with inguinal hernia is high,and the degree of adhesion of the hernia ring,BMI index are the independent risk factors of complications,target measures should be taken before operation.

Medicine is a practical science which needs comprehensive analysis.The old fashion of disease treatment model divided by different professions or departments was gradually unable to meet the needs of the clinical diagnosis and treatment,and the corresponding medical education pattern was very limited.As the development of multi disciplinary treatment (MDT) focused on a certain disease or organ,medical teaching mode also changed.Since our hospital used MDT as the treatment of severe acute pancreatitis (SAP),teaching model has been reformed by launching the joint multidisciplinary teaching.After that,the graduate students and advanced students from relevant departments have greatly improved their diagnosis and treatment skills.

The metastases status of internal mammary lymph node(IMLN) is an independent prognostic factor for breast cancer and it also is an important reference for neoplasm staging.The patients with IMLN metastases consistently have worse outcomes.The overall risk of IMLN metastases is 18 ％-33 ％.Metastases exclusively situated in the IMLN,without concurrent axillary metastases,occur in 2 ％-11％ of patients.Factors related to IMLN metastases include the status of axillary node,the age of patients,the localization and characteristics of primary tumor.Recently,with the development of sentinel lymph node biopsy(SLNB), internal mammary-SLNB may access the status of IMLN with a minimal risk. Internal mammary-SLNB procedure can improve the system for nodal staging of breast cancer,and it will contribute to the individualized treatment for breast cancer patients.
