Objective To evaluate the effects of statins on the cerebral haemodynamics of ischemic stroke patients with transcranial Doppler(TCD). Methods 70 inpatients with acute ischemic stroke were divided into two groups according whether they had taken statins after stroke.The change of the cerebral haemodynamics was studied in the two groups with TCD three months after stroke. Results Three months later,the systolic flow velocities and mean flow velocities of bilateral middle cerebral arteries in the statins groups significantly increased (P＜0.05). The pulse index of bilateral middle cerebral arteries in statins group significantly decreased (P＜0.05).The flow velocities and pulse index of bilateral middle cerebral arteries in control group don't change significantly(P＞0.05). Conclusions Statins may have the effects of improving the situation of cerebral haemodynamics of patients with ischemic stroke.

OBJECTIVE: To study the antibacterial activity of meropenem in vitro and the pharmacokinetics of which in patients with burn injury. METHODS: The minimal inhibition concentration (MIC) of meropenem against 136 clinical isolates was determined with double agar dilution method. 28 patients with burn injury were given 0.5g of meropenem by iv gtt, with the blood concentration of meropenem and the recovery of meropenem in urine were determined at different time. The pharmacokinetics parameters were computed with 3p97 software. RESULTS: Meropenem showed a strong antibacterial activity against K.peneumoniae, pneumonococcus and Enterobacter cloacae. MIC90 was below 0.0 075～0.25?g/ml. Pharmacokinetics parameters of meropenem were the following: t1/2? was (0.35?0.12) h,t1/2? was (2.10?0.71) h,AUC was (44.62?12.95) ?g/ml,Vc was (10.60?3.93) L; CLs was (12.00?3.04) L/h. 6.5 hours later, the mean blood concentration was (1.01?0.53)?g/ml; and the recovery of meropenem in 0h～12h urine was (58.06?16.83) %. CONCLUSIONS: Meropenem showed a very strong antibacterial activity in this study,there were significant differences regarding the in vivo pharmacokinetics parameters between the healthy volunteers and the patients with burn injury.

Objective To evaluate the clinical effect of ultrasound-guided percutaneous transhepatic cholangial drainage (PTCD) combined with endoscopic retrograde cholangio-pancreatography (ERCP) in treating malignant obstructive jaundice, and to discuss its technical points. Methods A total of ten cases with malignant biliary obstruction were enrolled in this study. After the failure of ERCP treatment, the patients had to be treated with ultrasound-guided PTCD immediately. The guide-wire was inserted into the duodenum through intrahepatic bile duct and common bile duct to connect with ERCP, which was followed by the biliary stent implantation or the removal of physical factors causing obstruction. The clinical results were analyzed. Results Technical success was obtained in all 10 cases. In the patients who underwent a successful guide-wire docking with ERCP the postoperative serum bilirubin was significantly decreased. The main complications were fever, elevation of amylase and transient bloody bile. Conclusion With the help of docking technique the combination use of ultrasound-guided PTCD and ERCP is a new tentative treatment for malignant obstructive jaundice after the failure of initial ERCP treatment. This technique carries promising value in clinical practice as it can significantly increase the success rate of ERCP.

Objective To discuss the effect and safety about large dosage of tilofiban injection into coronary artery in patients with ST-segment elevated myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods A prospective study was conducted. Two hundred and eighteen patients with STEMI admitted into Cardiology Department of Taizhou Central Hospital were enrolled. According to the difference in dosage, they were divided into a large dosage tilofiban group (102 cases) and a routine dosage tilofiban group (116 cases). In both groups, they received the injection of load dosage of tilofiban into coronary artery during they underwent primary PCI, the load dosage being 25μg/kg in the large dosage group, and 10μg/kg in the routine dosage group. Afterwards, the dosage was kept on 0.15μg·kg-1·min-1 in both groups lasting for 18-24 hours. The flow of thrombolysis in myocardial infarction (TIMI) immediately after PCI, the return of ST-segment after operation for 2 hours, the rate of bleeding events, the rate of major adverse cardiac event [MACE, including death, re-infarction and target vessel revascularization (TVR)] and prognosis after operation for 30 days were observed. Results The ratios of the immediate reflow of TIMI 3 grade after operation and the return of ST-segment after operation for 2 hours in the large dosage tirofiban group were higher than those in the routine dosage tirofiban group [the ratio of the reflow of TIMI 3 grade:92.16%(94/102) vs. 81.90%(95/116), the ratio of the return of ST-segment after operation for 2 hours:89.22%(91/102) vs. 73.28%(85/116), both P < 0.05]. The ratios of re-infarction, TVR and the total MACE in 30 days after operation in large dosage tirofiban group were lower than those in the routine dosage tirofiban group [re-infarction: 0.98% (1/102) vs. 2.59% (3/116), TVR: 0.98% (1/102) vs. 2.59% (3/116), total MACE: 1.96% (2/102) vs. 6.03% (7/116), all P < 0.05]. There were no statistically significant differences in mortality and the bleeding events between the large dosage tirofiban group and routine dosage tirofiban group [mortality:0 (0/102) vs. 0.86%(1/116), bleeding events:1.96%(2/102) vs. 0.86%(1/116), both P>0.05]. Conclusion The injection of a large dosage of tilofiban into a coronary artery in patients with STEMI undergoing primary PCI is an effective and safe method to allow them to get more clinical benefits.
