Objective To study the clinical features of large-artery atherosclerosis cerebral infarction and perforating artery disease type cerebral infarction.Methods Ninety cases of large-artery atherosclerosis cerebral infarction were set as the observation group and 90 cases of perforating artery disease type cerebral infarction as the control group.The general data and clinical characteristics were performed the comparative analysis.Results The drinking and smoking rates in the observation group were 43.33 ％ and 54.44 ％ respectively,which were in turn higher than 27.78 ％ and 25.56 ％in the control group;the occurrence rates of complicating coronary heart disease and lipid metabolism abnormality in the observation group were 45.56 ％and 58.89 ％respectively,which were in turn higher than 21.11 ％ and 37.78 ％in the control group;while the occurrence rate of complicating diabetes mellitus in the control group was 65.56 ％,which was higher than 42.22％ in the observation group,the differences were statistically significant(P＜0.05).Plasma oxidized low density lipoprotein and circulating endothelial cell count in the observation group were (687 ± 169)g/L and(9.0 ±1.7) × 106/L respectively,which were significantly higher than the normal level in the control group,the level of nitric oxide in the observation group was(77.4±21.1)mol/L,which was lower than that in the control group.The differences between the two groups were statistically significant(P＜0.05).Conclusion The onset factors of large artery atherosclerosis cerebral infarction have larger relation with drinking,smoking,complicating coronary heart disease and lipid metabolism abnormality,while perforating artery disease type cerebral infarction is more related with diabetes.

Irritable Bowel Syndrome(IBS) is a common disease of intestinal disorder.It is characterized by chronic or recurrent abdominal pain or discomfort along with altered bowel function.The underlying mechanisms of IBS remain unclear.Several studies showed that the attack of IBS might be related to the gastrointestinal motility,visceral hypersensitivity,infection of the bowel and several other factors.Existing animal models can be divided into 2 broad categories based on their primary pathogenetic mechanisms: those initiated by a central nervous system-directed(psychosocial) stressor and those stems from a gut-directed stressor(gut inflammation,infection).This article reviews the current research of IBS animal model.

Objective To evaluate the safety of conscious venous anesthesia with fentanyl and propofol in elderly patients over 70 during gastrointestinal endoscopy. Methods Clinical data of 826 elderly patients over 70, who underwent gastrointestinal endoscopy with venous anesthesia, were retrospectively analyzed. The patients were divided into 2 groups according to their ages, with 618 patients aging from 70 to 80 in group A, in which 342 received endoscopy and 276 underwent colonoscopy, and 208 patients older than 80 in group B, in which 112 underwent endoscopy and 96 had colonoscopy. Another cohort of 600 patients younger than 70, who underwent venous anesthetic endoscopy during the same time period, was randomly selected as the control group, in which 400 patients received endoscopy and 200 had colonoscopy. Blood pressure, heart rate, peripheral oxygen saturation (SpO2) and adverse reaction were monitored in each patient during the procedure and compared among different groups. Results No procedure-related perforation or sedation-related mortality was observed, and no procedure was terminated clue to sedation complication. The average dosages of propofol used in procedure of endoscopy in groups A, B and control were 54.22±21.36 mg, 40.22±12.46 mg, and 86.44±34.26 mg, respectively. The average dosages of propofol in colonoscopy were 82.56±40.64 mg, 45.36±15.44 mg and 102.23±46.32 mg, respectively. With same procedure, there was no significant difference in heart rate and blood pressure among different groups, nor was there any difference in these variables before and after the procedure in each group (P>0.05). Sedation exerted more influence on SpO<,2> in elderly patients. A total of 18 cases in groups A and B experienced SpO<,2> <90%, which was mainly due to aspiration of saliva and relieved by oxygen inhalation. Conclusion Under appropriate monitor, it is safe and feasible to give conscious sedation to elderly patients over 70 during gastroimestinal endoscopy.

To support the ongoing health reform in China,Chongqing municipal government made the decision in 2008 "Building Healthy Chongqing" ,and pinpointed for the first time regional development as a key goal.In line with this situation,the hospital proposed such hypothesis changes as from "disease hypothesis to "health hypothesis",from "illness oriented" to "capability oriented",and from "shaping development" to "adaptive development",as well as from one-sided efforts of medical staff to minimize casualty to joint efforts with patients to safeguard life and health.Focusing on these four strategic shifts,the hospital works in developing its "technical attraction,service capacity,innovation capacity,and emergency assurance capability,and management soft power",aiming at building a sustainable hospital in its development.

Objective To evaluate the clinical significance of phural effusion and/or ascites and their prognostic role in patients with acute pancreatitis.Methods The clinical data of 312 patients with acute pancreatitis were collected and analyzed retrospectively.Results Pieural effusion was found in 47 patients and ascites in 18.of 47 cases with pleural effusion,there were 31 cases(65.9%)of severe pancreatitis(P＜0.01)and 27 cases (57.4%)complicated by pseudocyst(P＜0.01).Among 18 cases with ascites,there were 14 cases(77.7%)of severe pancreatitis(P＜0.01).6 cases with pleural effusion and/or ascites died of multiple organs failure.Conclusion Pleural effusion and/or aseites is closely associated with severe pancreatitis.

Syncope is a common pediatric emergency event,which can be caused by various metabolic disorders different from other illness. The major metabolic anomalies include hypoglycemia, hyperventilation,electrolytes imbalance,hypoxemia and others, in which hypoglycemia is caused by hyperinsulinemia,pituitary and adrenal disease, diabetes, ketotic hypoglycemia, inherited metabolic disorders of sugar, organic acids and amino-acids,etc. This article introduced the common metabolic anomalies and their causes,diagnosis and therapy.

Objective:To investigate the effects of thyroid motilin(MTL) on migrating motor complex(MMC) in fasting rats.Methods: The distribution and quantitative expression of motilin in the thyroids were detected by immunohistochemistry and radioimmunoassay.We also observed the effect of thyriod motilin on the MMC by recording the gastrointestinal motility in conscious rats.Results: Tail vein injection of MTL increased MMC in antrum and duodenum in a dose-dependent manner,as manifested by increased contraction frequency and amplitude(P

Functional magnetic resonance imaging(fMRI) is a very powerful method to understand the mechanism of brain function with non-invasive localization, high spatial and temporal resolution. The essential fMRI technique is blood oxygen level dependent (BOLD-fMRI). Basic principles and methodological applications of BOLD-fMRI are reviewed in this paper.

[Objective]To investigate a minimally invasive,safe and effective method for treating the nonunion of tibia fracture with Bastianti external fixators.[Method]Bastianti external fixators were used to treat nonunion tibia fracture with axial force followed by functional exercises in early stage.[Result]All cases showed tibia fracture union in 4~12 months after operation.According to the criterion of treatment effects,35 cases were as excellent,7 as good,and 1 as poor.[Conclusion]It is a good method that nonunion of tibia fracture was treated with Bastianti external fixators for maintaining pain-free joint activity and joint functional recovery in early stage.

Objective To study the efficacy and safety of methylcarboprost suppository in preventing postpartum hemorrhage of cesarean section.Methods Two hundred and nine puerperants with cesarean section were randomly divided into two groups: test group(n=103),1mg methylcarboprost suppository was given sublingually after peritoneotomy,and control group(n=106),20IU oxytocin intravenous drip immediately after neonate delivery. 20IU oxytocin were injected into uterine muscularis in the both groups after neonate delivery.The amount of bleeding in perioperation and 24 hours after delivery were measured.Results The blood loss volumes in perioperation and 24hour after delivery in test group were 191 2ml and 317 2ml respectively, and in control group were 216 6ml and 350 5ml respectively,and there was significant difference in the blood loss volume between the two groups(P
