Objective To compare the risk of bleeding between Clopidogrel and Ticagrelor in inpatients with acute coronary syndrome. Methods 264 patients with acute coronary syndrome who were admitted to our hospital from January 2016 to October 2016 were selected. The patients were divided into two groups randomly, 131 cases with taking Ticagrelor tablets and 133 cases with taking Clopidogrel tablets. The risk of bleeding of the two groups were compared.

Objective To evaluate the effect of LCVP applied during the operation of hepatectomy.Methods Sixty patients underwent hepatectomy were enrolled in the study from March 2010 to March 2012 in our hospital which were randomized into LCVP group and normal CVP (NCVP) group by the sealed envelope method. CVP was kept<0.5 kPa during entire procedure of hepatectomy in LCVP group, and the value of CVP and blood pressure were controlled within 10% of the baseline. The same anesthesia, incision and hepatectomy technique and indications of blood transfusion in LCVP group were undertaken as those in NCVP group.

The time of operation, the amount of bleeding, the extent of removed hepatic tissue, the amount of transfused blood products,liver and renal function index, and coagulation function index were detected on the 1st, 3rd and 7th day after operation. Also the supplement of albumin, the rate of postoperation complications and the length of hospital stay and the expense in hospital were recorded.Results ① The general clinical data of patients were similar in the two group (P>0.05). ② The operation time, total bleeding volume, bleeding volume and RBC infusion volume in LCVP group were significantly lower than those in group NCVP (P<0.05). ③ There were no significant difference of postoperative liver and renal function index between the two groups (P>0.05). But the supplement of albumin in LCVP group after operation was significant less than that in NCVP group (P<0.05). ④ There were no significant difference of the postoperative complication, the length of hospital stay and the expense in hospital between the two groups (P>0.05).Conclusions The application of LCVP in hepatectomy cause less blood loss, shorten the length of hospital stay and decrease the expense in hospital, which is beneficial for the postoperative recovery.

Objective To evaluate the clinic value the technique of Cuboid stereotactic catheter (TCSC) in the treatment of small-volume traumatic extradural hematoma in non-functional areas.Methods We performed a retrospectively analysis of 65 patients with small-volume(15-30 mL) traumatic extradural hematoma in non-functional areas. All of which were divided into two groups according to the different treatments. 35 cases treated with drugs were control group, while the rest of 30 cases with both drugs and TSCS were treatment group. The complication incidence and hematoma clearance rate in hospitalization time, recurrence rate of headache, anxiety,hematoma clearance rate at 3 and 6 months follow-up were compared between the two groups.Results The hematoma clearance rate in control group and treatment group were 25.7% and 66.7%,respectively. (P=0.001), while the complication rate was no obvious differences. The recurrence rate of headache, anxiety and hematoma clearance rate at 3 months follow-up were different between the two groups. These conditions were not happened at 6 months follow-up.Conclusion TCSC may eliminate the hematoma within a short hospitalization time by avoiding extra complication coincidence, improve the short-term life quality of patients such as relief the symptoms like headache and anxiety in the patients with small-volume(15~30 mL) traumatic extradural hematoma in non-functional areas. Above of results indicates the impact of this technique on neurosurgical practice.
