Objective To investigate the effect of rivaroxaban on prevention from deep venous thrombosis after hip replacement surgery .Methods 80 patients with lower limb parallel arthroplasty were randomly divided into observation group and control group from January 2014 to January 2015.40 cases in each group.Control group was given aspirin treatment, observation group was given rivaroxaban treatment, indicators changes were followed up and recorded.Results PT, APTT values of observation group one week after treatment were (35.79 ±2.16),(15.84 ±2.11) s, which were better than control group (45.64 ±2.12),(18.72 ±2.02) s (P<0.05).TT, D-dimer of observation group(13.48 ±2.10)s,(2.34 ±0.33)g/L after a week were better,than control group (16.38 ±1.79)s, (1.42 ±0.21)g/L (P<0.05) respectively.Conclusion Effect of rivaroxaban in prevent deep venous thrombosis after hip replacement surgery is exact without obvious adverses reaction, it is worthy of further research and application.

Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.

Objective To understand the clinical profiles of arthritis after human parvovirus B19(B19) infection.Methods Four cases were described and the clinical and laboratory characteristics were analyzed. Results The median onset age of the 4 patients(2 females and 2 males)was 34 years old.Typical clinical manifestations included joint symptoms,flu-like malaise and erythematous rash.Anti-Bl9 IgM antibodies were all positive in 4 patients.B19 DNA was detected in blood samples of 3.Other types of arthritis were excluded. No relapses were noticed after followed-up of 1～3 years.Conclusion The Anti-B19 lgM and B19 DNA should be detected in patients suffer from arthritis with unknown origin.

By analysis on existing problems of the classification, the suggestions were put forward to provide a reference for improving the classification of medical devices.

Objective To evaluate the feasibility and therapeutic efficacy of prophylactic implantation of intraaortic balloon pump in patients with high-risk coronary artery disease.Methods 121 patients with high-risk coronary heart disease who received prophylactic implantation of intraaortic balloon pump in percutaneous coronary intervention were enrolled as the treatment group (Group A),and another 119 patients with high-risk coronary heart disease who had conventional coronary intervention were enrolled as the control group (Group B).The rates of intraoperative malignant arrhythmia (ventricular tachycardia,ventricular fibrillation),acute left heart failure,cardiogenic shock and sudden death were compared between the two group.NT-proBNP levels,left ventricular systolic function and the rates of major adverse cardiac events,within 30 days of PCI and after 1 year were compared between the two groups.Results The event rates of intraoperative malignant arrhythmia,acute left heart failure,cardiogenic shock,and sudden death in Group A was significantly lower than those in Group B (all P ＜ 0.05).Postoperative hematoma were found in 2 cases,aortic dissection in 1 case and thrombocytopenia in 1 case in Group A without significant difference as compared to Group B (P ＞ 0.05).Within 30 days after PCI,NT-proBNP levels and left ventricular diastolic diameter in Group A were lower than those in Group B while the left ventricular ejection fraction in Group A was higher than that in Group B (all P ＜ 0.05).The rates of major cardiac adverse events,including sudden cardiac death and severe heart failure were lower than those in Group B (all P ＜ 0.05).At 1 year after PCI,the NT-proBNP levels left ventricular diastolic diameter in Group A were lower than those in Group B with the left ventricular ejection fraction in Group A was higher than that in Group B (all P ＜ 0.05).There were no significant differences in the rates of major cardiac adverse events,including sudden cardiac death and severe heart failure after 1 year(all P ＞ 0.05).Conclusions For patients with high-risk coronary heart disease undergoing coronary intervention,prophylactic implantation of intraaortic balloon pump may decrease the incidence of intraoperative complications,reduce the incidence of cardiac death and severe heart failure within 30 days,and improve the left ventricular function after 1 year.Its role in reducing long term major cardiac adverse events after 1 year still needs more clinical trials for funther justification.

Objective To observe apoptosis of renal development in mouse. Methods Light,electron microscopy and TUNEL method were used. Results The apoptosis could be easily found in cells between S like body in nephrogenic zone and in renal corpuscles before birth, especially at 14 18 days prenatally. The apoptotic cells in epithelia of renal tubule or collecting duct could be observed in postnatal renal medulla. In medullary papilla the cell death peaked around postnatal day 7. Electron microscopy revealed that apoptotic cells were ingested by neighboring cells. Some apoptotic cells detached from epithelia into the lumen of tubule or duct. Conclusion This study provides morphologically some evidences of apoptosis in the mouse kidney embryonically and postnatally. The apoptosis in cortex was apparently related to the development of nephrogenic zone and renal corpuscles; and the apoptosis in medulla might play an important role in the development of renal tubular epithelia.

Objective:To study the effects of Docetaxel o n the proliferation of adenoid cystic carcinoma SACC-83 cells of salivary gland. Methods:The inhibitory effects of Docetaxel on the proliferatio n of SACC-83 cells were investigated with cell counting, soft agar clonogenic a ssay, and flow cytometry. Results:With the exposure time of 24, 48 or 72 h the IC 30(nmol/L) of Docetaxel was 1.39,1.26 and 0.47, the I C 50(nmol/L) 13.02, 3.34 and 1.26 respectively; the relative antitumor acti vity (RAA) of the drug against SACC-83 cells was 330, 1 289 and 3 426 respectiv ely. After the cells had been treated for 72 h, the percentages of G 1, S and G 2 phase cells in the cell cycle in the control group were 73.8,19.8 and 6.4, in IC 30 group 65.0, 29.5 and 5.5, in IC 50 group 57.6,42.4 and 0, res pectively. The clonogenesity (%) in control, IC 30 and IC 50 groups we re 36.0?0.5,8.3?2.5 and 0.5?0.3 respectively. Conclusion:Doc etaxel may inhibit the proliferation of SACC-83 cells in a dose and time depend ent way.

With building up a clinical modification system model by upgrading the standard disease classification system architecture,to collect those huge amount of diagnosis names and codes in use,based on the model to screen and coordinate the relation of them,the tenth revision of the International Classification of Disease Clinical Modification of Beijing is implemented.This standard has been successfully applied for two years in all those secondary and above level hospitals in Beijing.It could well support the work of deploying Diagnosis Related Groups in Beijing and support not only those traditional applications of disease classification but also those new and advance requirements of information processing.
