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.

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.

Corn meal was hydrolyzed in HCI ,and pH adjusted to 6.8 with (NH_4)OH. The substrate was inoculated with Cadida trapicalis ,then cultivated in a shaker at 30℃ and in 200r/min for 2 days. The Results indicated that the protein content in corn meal grew from 8.4 to 27.4%the lysine in the protein increased from 32.1 to 73.48/kg,the tryptophan from 6.8 to to 14.8g/kg. This shows that the nutritional value of corn meal can be improved with this method.

There are some issues with the payment mechanism in the hospital at present.For instant, lacking of the government subsidy,collecting money depending on drug and the price is unreasonable.All of these issues restrict the development of health care system,and influence the health care delivery and the cost control.The article suggests the following working must be well done:to strengthen the regionol plan- ning in order to prefer the rural area;defining the accountability.of the government for health care;dividing treatment and selling drug into two groups;reforming the price of health care service.

Mast cells regulate inflammation and immunity.Experimentally induced abdominal aortic aneurysm in mast cells-deficient animals and animals treated with mast cells inhibitors demonstrate that mast cells are involved in the pathogenesis of abdominal aortic aneurysm via several different mechanisms.Mast cells-dependent activation of metalloproteinases and the renin-angiotensin system,contribution to smooth muscle cell apoptosis,and release of proteolytic enzymes are some key examples.Activated mast cells also contribute to neovascularization,inflammation,and atherosclerosis,all hallmarks of abdominal aortic aneurysm.Thus,we may envision that mast cells stabilizing agents,as well as leukotriene receptor antagonists and histamine receptor blockers already in clinical use for treatment of other diseases,could also be tested for their efficacy in treatment of abdominal aortic aneurysm.

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.
