3.Effects of atorvastatin calcium on circulating endothelial progenitor cells in renovascular hypertensive rats
Chinese Journal of Tissue Engineering Research 2009;13(46):9133-9137
BACKGROUND:The quantity and function reduction of circulating endothelial progenitor cells(CEPCs)indicate that vascular endothelial repair capacity reduces in hypertension patients,but the impact of statins on the CEPCs is still not very clear.OBJECTIVE:To investigate the effects of atorvastatin calcium on endothelial cells and CEPCs in renovascular hypertensive rats.DESIGN,TIME AND SETTING:Randomized controlled animal experiment was performed in Chongqing Key Laboratory ofNeurology from June 2008 to Febmary 2009.MATERIALS:Totally 24 SD male rats of SPF grade,and atorvastatin calcium was produced by Lipitor,Pfizer Inc.with batch number of 65837003.METHODS:The renovascular hypertension was induced with 2-kindey and 1-clip method in 16 SD rats,which were then randomly divided into two groups:hypertensive group(n=8)and statins group(n=8).control group(n=8)underwent the same operation,without silver slip.At 4 weeks after model construction,statins group was treated with atorvastatin calcium MAIN OUTCOME MEASURES:At 4 and 12 weeks of the experiment.three groups of rats were measured blood pressure and blood lipids;at 12 weeks,the thoracic aortic endothelial cells continuity was investigated through hematoxylin-eosin stain;the quantity,proliferation,adhesion and migration capacity of CEPCs were determined.RESULTS:At 4 and 12 weeks of the experiment,there was no significant differences in the systolic pressure between statins RESULTS:At 4 and 12 weeks of the experiment,there was no significant differences in the systolic pressure between statins group group and model group,which were dramatically high than control group(P>0.01):the blood lipids in the statins group was not changed.In the model group,rat aortic endothelial cells were greatly damaged;the injury of CEPCs was dramatically relieved in the model group.Compared with statins group and control group,the number of CEPCs was significantly decreased,the capacities of proliferation,adhesion and migration were also significantly reduced in the model group(P<0.01);moreover,statins group was inferior to control group in terms of these capacities.with significant differences among three groups(P<0.01).CONCLUSION:Renovascular hypertensive rats thoracic aortic endothelial calls are severely damaged,CEPCs decline in the humber and function;atorvastatin calcium can increase the number of CEPCs and improve the function of CEPCs.
4.Endovascular therapy for intracranial wide-necked aneurysms
Journal of Interventional Radiology 2009;18(9):645-648
Objective To summarize the clinical experience of intracranial wide-necked aneurysms using intracranial stent technique or balloon-assisted technique. Methods Thirty-three ruptured intracranial wide-necked aneurysms were treated by stent-assisted or balloon-assisted technique combined with the use of Microplex coils. The lesions included 8 anterior communicating artery aneurysms, 19 posterior communicating artery aneurysms, 3 middle cerebral artery aneurysms and 3 basilar artery aneurysms. Results Of 19 patients treated with stent-assisted technique and Microplex coils, complete occlusion of the aneurysm was achieved in 13, over 90% occlusion in 4 and (70-90) % occlusion in 2. Among another 14 patients treated with balloon-assisted technique and Microplex coils, complete occlusion of the aneurysm was achieved in 9, over 90% occlusion in 3 and (70-90) % occlusion in 2. Conclusion For the treatment of intracranial wide-necked aneurysms, both the stent-assisted and balloon-assisted techniques are safe and effective. In treating intracranial wide-necked aneurysm, the selection of proper technique should be based on the patient's individual condition.

6.Research on the compensation mechanism in public hospitals practicing the zero price margin for drugs
Chinese Journal of Hospital Administration 2012;28(5):321-324
The paper analyzed the compensation mechanism applied in public hospitals in different localities in China,which are currently experimenting with the zero price margin for drugs.It also introduced the revenue variations resulting from this practice.It is discovered that public hospitals can hardly make their ends meet with merely governmental financial input,and that lowered income of doctors and price distortion arc evident in those experimental hospitals,with little progress in overcoming the subsidization of medical services with drug sales.The authors recommended a comprehensive reform,the mechanism of diversified health input,change of internal incentive mechanism within the hospital,improvement in the healthcare service pricing mechanism,and exploration of new operation mechanisms for public hospitals.

Chinese Journal of Bases and Clinics in General Surgery 2003;0(04):-
Objective To investigate the clinical significance of routine application of choledochoscope during operation of biliary duct.Methods The clinical data of 136 patients with the routine application of intraoperative choledochoscope dealing with bile duct diseases in this hospital from October 2003 to July 2009 were analyzed and summarized.Results Intraoperative choledochoscope inspection,taking stones and targeted surgery were performed in 116 cases with extrahepatic and (or) intrahepatic bile duct stones.The taking out rate of extrahepatic bile duct stones was 100% (85/85),the residual stone rates of extrahepatic and intrahepatic bile duct were 0 (0/85) and 22.6% (7/31),respectively,with the total residual stone rate was 6.0% (7/116).By using intraoperative choledochoscope,benign intrahepatic bile duct stricture was found in 13 cases,malignant extrahepatic and intrahepatic bile duct stricture in 8 cases.Four cases of hilar cholangiocarcinoma and 4 cases of common bile duct cancer,2 cases of lower segment of common bile duct polyp,3 cases of hepatolithiasis with the left hepatic bile duct carcinoma were diagnosed by biopsy via choledochoscope.Causes were confirmed by applying choledochoscope in 16 patients with obstructive jaundice.The use of choledochoscope with surgical treatment enabled benign and malignant bile duct stricture to achieve good results,without serious complications such as bile duct dilaceration,subphrenic abscess or acute cholangitis.Conclusions Using choledochoscope can tremendously reduce the residual rate of stone in biliary duct surgery,increase the definite diagnosis rate of biliary duct diseases and play a role of reasonable instruction in its treatment options.It has unique advantages in identifying causes of jaundice.It is remarkable that the role of applying choledochoscope to diagnose and cure biliary duct diseases.It should be widely used.

10.Perspective on the application of nanoparticules as drug delivery and control release systems
Basic & Clinical Medicine 2006;0(07):-
Nanoparticule (NP) as a drug and gene carrier has shown great potential and has been widely studied. Due to its ultra-small size, NP can achieve intelligent delivery of drugs, such as deliver drug site-specifically to disease focus or targeted tissue, even into target cells. The carrier materials of NPs provide it with such advantages as shielding odor, long-term sustained releasing of drug, lowering uoxicity,extend biologic half life of drug and gene, etc. This review emphasizes the manufacturing techniques and application of nanoparticles as drug and gene delivery system.
