Objective To evaluate the efficiency and safety of Percusurge guardwire distal protection system in coronary intervention in patients with acute myocardial infarction. Methods Three male patients with acute myocardial infarction were enrolled in the study. Primary angioplasty was performed for 2 of them, 2 and 7 hours after onset of the infarction symptom, respectively. Selective angioplasty was performed 17 days after infarction for the third case. Percusurge guardwire system was used during the procedure. Results Procedure success was achieved for all of the 3 cases. Lot of thrombus was sucked out. The infarct-related arteries had TIMI 3 flow at the end of the procedures. The patients′ symptoms were resolved soon after the procedure. Minor dissection was seen in one case which did not obstruct the distal flow and was left alone. Conclusion Percusurge guardwire system can be used safely and effectively in coronary intervention in the thrombus-laden arteries such as acute myocardial infarction.

Objective To study the characteristics of infarct-related-artery (IRA) in acute high lateral wall myocardial infarction and to give clinical clue for deducing the location of coronary artery lesions. Methods Ninety-six patients with acute high lateral wall myocardial infarction (77 males, 19 females, mean age 57.3?10.7 years) were enrolled in the study. They all had infarction for the first time and were confirmed to have single vessel coronary artery disease by coronary angiography. The patients were divided into 3 groups according to the ECG changes at the onset of infarction. The first group (group A) was simple high lateral wall infartion (23 cases). The second one (group B) was high lateral with anterior wall infarction (58 cases, among them 27 cases with anteral-septal infarction and the other 31 with extensive anterior infarction). The third group (group C) was high lateral with lateral wall infarction (15 cases). Lesion characteristics of IRA were analyzed. Results The infarction-related lesions were mainly on left anterior descending arteries in group B (56/58), and on left circumflex in group C (13/15). But those in group A could be on either diagonal (12/23) or left circumflex (11/23). The difference of distribution of IRA among these groups was statistically significant (P

Objective To investigate the correlation between atherosclerotic renal artery stenosis and hypertension.Methods One hundred and seventy-nine patients underwent renal artery angiography after coronary artery angiography. Results Among the 179 patients, 56.4% patients were detected as renal artery normal, 24% as renal artery disease, and 19.6% as renal artery stenosis. Compared with hypertensive patients with normal renal artery, ARAS patients had higher systolic blood pressure (148?23 mm?Hg vs 136?18 mm?Hg, P

Objective To identify the key factors triggering medical disputes induced by differences in cognition between doctors and patients in order to control the occurrence and development of medical disputes. Methods From 2002 to 2006,the outpatients,inpatients and medical staff of 3 hospitals in Shanghai(class 3 first level general hospital,n=2;class 3 first level special hospital,n=1) were investigated,and random sampling method was employed for the research analysis. Results There were significant differences between doctors and patients in cognition of influential factors triggering medical disputes such as health law,medical services,rights and obligations. Conclusion The differences in cognition between doctors and patients are important causes for medical disputes,and effective prevention and intervention measures must be taken.

Mucosal adjuvants play important roles in vaccine development. By now, the common used mucosal adjuvants can be divided into three categories: the bacterial derivatives, cytokines and chemokines, and antigen delivery systems. Progresses of the three kinds of adjuvants were reviewed to give a reference to novel vaccine research.

OBJECTIVEThis study aims to test the accuracy and precision of iWitness photogrammetry for measuring the facial tissues of mannequin head.

METHODSUnder ideal circumstances, the 3D landmark coordinates were repeatedly obtained from a mannequin head using iWitness photogrammetric system with different parameters, to examine the precision of this system. The differences between the 3D data and their true distance values of mannequin head were computed.

RESULTSOperator error of 3D system in non-zoom and zoom status were 0.20 mm and 0.09 mm, and the difference was significant (P 0.05). Image captured error of 3D system was 0.283 mm, and there was no significant difference compared with the same group of images (P>0.05). Error of 3D systen with recalibration was 0.251 mm, and the difference was not statistically significant compared with image captured error (P>0.05). Good congruence was observed between means derived from the 3D photos and direct anthropometry, with difference ranging from -0.4 mm to +0.4 mm.

CONCLUSIONThis study provides further evidence of the high reliability of iWitness photogrammetry for several craniofacial measurements, including landmarks and inter-landmark distances. The evaluated system can be recommended for the evaluation and documentation of the facial surface.

Objective To investigate the risk factors of gallbladder carcinoma,so as to provide theoretical base for the prevention of gallbladder carcinoma.Methods The clinical data of 153 patients with gallbladder carcinoma (gallbladder carcinoma group) who were admitted to the Peking Union Medical College Hospital from January 2000 to December 2010 were retrospectively analyzed. A total of 300 patients with cholecystolithiasis (cholecystolithiasis group) and 300 patients without gallbladder carcinoma or cholecystolithiasis (control group)were collected and matched at the ratio of 1∶2 to conduct the controlled study.Data were statistically analyzed by the Chi-square test and conditional Logistric regression.Results Univariate analysis showed significant difference in age,history of cholecystolithiasis,postmenopausal age,accumulated menstrual period,giving birth or not and number of birth between gallbladder carcinoma group and control group ( x2 =58.22,180.14,9.59,24.30,18.66,15.17,P ＜0.05).Age,history of cholecystolithiasis,accumulated menstrual period and number of birth were the independent risk factors of gallbladder carcinoma (x2 =55.76,180.95,24.30,8.54,P ＜ 0.05).The risk of having gallbladder carcinoma in patients who had a history of cholecystolithiasis was 34 times higher than those who did not have the history of cholecystolithiasis (OR =34.22).Late postmenopausal age (51 -55 years old),longer accumulated menstrual period ( ≥30 years),and the number of birth ( 3 times) were associated with higher risk of gallbladder carcinoma (OR =3.96,9.68,3.51 ). Age,course of cholecystolithiasis and accumulated menstrual period and number of birth were the risk factors of gallbladder carcinoma when comparing patients who have history of cholecystolithiasis in the gallbladder carcinoma group with those in the cholecystolithiasis group (x2 =70.66,16.66,11.59,4.69,P ＜ 0.05 ).Age,course of cholecystolithiasis and accumulated menstrual period were the independent risk factors of gallbladder carcinoma ( x2 =64.29,8.82,5.58,P ＜ 0.05).The risk of gallbladder carcinoma increased as the increase of age and course of cholecystolithiasis. The accumulated menstrual period ≥ 30 years was also a risk factor of gallbladder carcinoma. Conclusions Age,history of cholecystolithiasis,course of cholecystolithiasis,accumulated menstrual period and number of birth may be the risk factors of gallbladder carcinoma.For patients with age above 60 years and course of cholecystolithiasis above 3 years,cholecystectomy should be conducted to reduce the incidence of gallbladder carcinoma,and great importance should be attached to female patients with indications mentioned above.

Insulin resistance, lipid metabolism disorders, independent autonomic neuropathy are high risk factors for gallstone formation in type 2 diabetic patients. In recent years, there have been a lot of new developments on the relationship between type 2 diabetes and gallstones, such as adiponectin, leptin and metabolic syndrome, etc. Based on these studies, the risk factors of type 2 diabetes complicated with gallstones are summarized in this paper.

Objective To determine the risk factors of gallstones. Methods A case-control study was conducted on 4087 patients with gallstones (the study group) and 20435 individuals without gallstones (the control group) at the Health Center of Peking Union Medical College Hospital (PUMCH) between January 2007 to May 2010. Using age and sex, the study and the control groups were matched in 1 : 5 ratio. Data were statistically analyzed using Chi-square test and conditional logistic regression.Results Univariate analysis showed significant differences in diabetic mellitus (DM), systolic blood pressure (SBP), diastalic blood pressure (DBP), triglyceride (TG), high density lipoprotein cholesterol (HDL-CH) and body mass index (BMI) between the study and the control groups (P＜0.05). Multivariate analysis confirmed that DM, SBP, HDL-CH and BMI were associated with gallstones, and their adjusted odds ratio (95％ confidence interval) were 0. 825 (0. 736 ～0. 925), 0. 908 (0. 828～0. 996), 1. 211 (1. 056～1. 389) and 0. 746 (0. 691～0. 805), respectively.The incidences of total cholesterol (TCH) and low deasity dipoprotein cholesterol (LDL-CH) were not significantly different between the two groups (P＞0.05). ConclusionsDM、SBP、HDL-CH and BMI were found to be the risk factors for gallstones. To prevent gallstones, weight reduction, blood pressure control and normalization of blood lipid are important measures.
