Objective To investigate if isoflurane preconditioning induces ischemic tolerance against neuronal damage produced by middle cerebral artery occlusion (MCAO) in rats Methods Thirty male SD rats weighing 350 400g were randomly divided into three groups: control group (no pretreatment,n=10),isoflurane preconditioning group (ISO group) (inhalation of 2% isoflurane and 98% O 2 1h per day lasting 5d,n=10), oxygen preconditioning group (O 2 group) (inhalation of 98% O 2 1h per day lasting 5d ,n=10) Right MCAO was induced by a 3 0 nylon thread with round tip inserted cranially into right internal carotid artery under isoflurane anesthesia and maintained for 120 min The neurologic deficit score (NDS) was evaluated 1, 3, 6, 12, 16 and 24h after reperfusion and the infarct volume was calculated at 24th following reperfusion Results The NDS of ISO group was lower than that of other two groups at each time interval (P0 05) Conclusions Isoflurane pretreatment can induce ischemic tolerance against neuronal damage produced by transient MCAO in rats

Objective To study the clinical significance of the proinflammatory cytokines and anti-inflammatory cytokines in acute pancreatitis with systemic inflammatory response syndrome. MethodsIn this study, 13 cases of mild acute pancreatitis (MAP), and 19 cases of severe acute pancreatitis(SAP) were recruited to evaluate acute physiology and chronic health evaluation (APACHEⅡ) on post admission day 1,3,5,7 and Balthazar CT criteria on post admission day 1,7. Values of serum IL-6?IL-8?IL-10?IL-12 were measured. ResultsThe scores of APACHEⅡ and Balthazar CT criteria were lower in the MAP patients than those in the SAP patients(5.6?2.1 and 1.5?0.6 vs. 13.6?4.3 and 6.3?1.5, all P

Objective To evaluate the role of orexin in the sleep disorder after isoflurane anesthesia in rats.Methods Sixty-four male Sprague-Dawley rats,aged 10-12 weeks,weighing 280-320 g,were randomly divided into 2 groups (n =32 each) using a random number table:control group (C) and isoflurane group (Ⅰ).Group Ⅰ inhaled 1.2％ isoflurane from 8:00 to 13:30 to induce anesthesia,followed by 0.5 h of recovery.Group C received no anesthesia and the other procedures were similar to those previously described in group Ⅰ.The induction time and awakening time were recorded.Eight rats were randomly chosen to record the movement condition (locomotor time and activity) from 14:00 to 8:00 the next morning.Before beginning of anesthesia,at 4 h after beginning of anesthesia,and at 4 and 10 h after the end of anesthesia,6 rats were randomly chosen in each group to count the orexin/c-fos double-labeled neurons in hypothalamus.The ratio of activated orexin neurons (orexin/c-fos double-labeled neurons to orexin positive neurons) was calculated and plasma orexin-A concentration was detected.Results The induction time was (2.14 ± 0.17) min,awakening time was (8.7 ± 0.5) min,and EEG showed that there was no typical burst and suppression patterns in group Ⅰ.There was no significant difference in the number of orexin positive neurons between the two groups (P ＞ 0.05).Compared with group C,the time for locomotor activity was significantly prolonged,and the activity was increased during the night (P ＜ 0.01),the number of activated neurons,ratio of activated orexin neurons and plasma orexin-A concentration were decreased at 4 h after beginning of anesthesia in group Ⅰ (P ＜ 0.01).The plasma orexin-A concentration was lower at 4 h after beginning of anesthesia,while higher at 10 h after the end of anesthesia than before beginning of anesthesia in group Ⅰ (P ＜ 0.05).The number of activated neurons was significantly larger and ratio of activated orexin neurons was higher before beginning of anesthesia and at 10 h after the end of anesthesia and the plasma orexin-A concentration was higher at 4 and 10 h after the end of anesthesia than at 4 h after beginning of anesthesia in group Ⅰ (P ＜ 0.05 or 0.01).Conclusion The development of sleep disorder after isoflurane anesthesia during the day time in rats is related to the regulatory role of orexin in it.

Objective To investigate how to avoid and deal with injuries to the aberrant right posterior hepatic duct during laparoscopic cholecystectomy (LC).Method We studied 1 710 patients who underwent LC in our unit from January 2011 to November 2013.There were 5 patients with right posterior hepatic duct abnormally,and this paper analysed the cases.Results In the 5 patients,one patient had the right posterior hepatic duct draining into the gallbladder body (Ⅰ A type),two patients had the right posterior hepatic duct draining into the cystic duct (ⅢA type),and two patients had the cystic duct draining into the right posterior hepatic duct (ⅢB type).There was no damage to the right posterior hepatic duct during operation.One patient was converted from LC to open operation.The major aberrance was class Ⅲ.Conclusions Variant bile duct is an important cause of bile duct injuries during LC.The right posterior hepatic duct variation is the most common form.To raise our vigilance and fully understand the types of aberrant right posterior hepatic duct,reasonable use of preoperative MRCP and intraoperative cholangiography in selected patients are fundamental.Aberrant right posterior hepatic duct injuries can effectively be avoided.

Objective:Ischemic cerebral injury is a common complication during perioperative period.We found that ischemic postconditioning and various non-ischemic postconditioning(e.g.inhalation anesthetics) could significantly attenuate ischemic cerebral injury.The present study was to investigate the effect of Cyclosporin A on sevoflurane postconditioning in focal cerebral ischemia.Methods:Fifty male SD rats were randomly assigned to five groups (n=10 each): control group(con),1.0MAC group(sevo),1.0MAC+ Cyclosporin A group(sevo+CsA),1.0MAC+ vehicle group(sevo+vehicle)and Cyclosporin A group(CsA).All animals were subjected to right middle cerebral artery occlusion(MCAO) for 120min followed by reperfusion for 72h.The animals in sevo groups were given 1.0MAC sevoflurane inhalation from 20min before to 10min after reperfusion.The animals in CsA groups were given CsA by ICV injection before sevoflurane postconditioning.The neurological deficit scores(NDS) were recorded at 24h,48h,and 72h after reperfusion.Infarct volume percentage was determined after the last NDS assessment.Results:The infarct volume percentage ratio of Sevo, Sevo+CsA,CsA and Sevo+vehicle groups were 0.31?0.04,0.25?0.04,0.30?0.03 and 0.33?0.05,respectively(P

Objective To analyze the clinical and pathological features of upper gastrointestinal serrated lesions.Methods A total of 21 patients with upper gastrointestinal serrated lesions in Tianjin Medical University General Hospital between January 2011 and December 2015 were retrospective analyzed.Data of the patients including demographics, clinical and pathological features were collected.Among the 21 patients, 18 patients, who underwent colonoscopy simultaneously or within six months, were selected as the study group, each patient was compared to 4 randomly selected controls without serrated lesions, who also underwent colonoscopy within the same time period.Differences of colorectal neoplasia detection were analyzed between the cases and controls.Results The mean age of 21 patients was 55.3±17.2 years, and 11 cases were male.Involving the locations of serrated lesions, 17 cases were found in the stomach (including 3 in the cardia, 9 in the corpus, and 5 in the antrum), and followed by 3 in the duodenum and 1 in lower esophagus.The mucosa pathological morphology showed that 6 cases were serrated hyperplasia, 8 cases were hyperplastic polyps, 6 cases were serrated adenomas with low grade dysplasia and 1 case was in the duodenum intramucosal carcinoma.Seven (38.9%) colorectal adenomas were found in the study group, including 3 (16.7%) non-advanced colorectal adenomas and 4 (22.2%) advanced colorectal adenomas.Eight (11.1%) colorectal adenomas were found in the control group, including 5 (6.9%) non-advanced colorectal adenomas and 3 (4.2%) advanced colorectal adenomas.The rate of colorectal adenoma detection in the study group was significantly higher than that in the control group (38.9% VS 11.1%, P=0.010, OR=5.091, 95%CI:1.534-16.890).Conclusion Upper gastrointestinal serrated lesions can be found in various mucosal lesions with different pathological morphologies.Moreover colonoscopy is likely to be recommended to detect concurrent colorectal adenoma for these patients.

Objective:To evaluate the diagnostic efficiency of contrast-enhanced magnetic resonance angiography (CE-MRA), T 1WI and three-dimensional thin-layer T 1WI sequences (3D-T 1WI) in evaluating the blood supply of brain tumors, so as to improve the enhanced magnetic resonance imaging (MRI) scanning scheme of brain tumors. Methods:After the contrast agent was injected, 29 patients with brain tumors were scanned with CE-MRA, T 1WI and 3D-T 1WI. The imaging manifestations of " observing the enhancement of tumor substance" , " observing the small vessels in the tumor body" and " observing the small vessels around the tumor" were qualitatively classified, and the diagnostic differences of the three sequences were analyzed by McNemar test. Results:⑴ In the aspect of " observing the contrast medium in the tumor body" , CE-MRA, T 1WI and 3D-T 1WI sequences diagnosed as grade A1 were 0 cases, 8 cases (27.59%) and 19 cases (65.52%) respectively. The diagnostic efficiency of 3D-T 1WI sequences was better than that of T 1WI sequence ( P<0.05), and T 1WI sequence was better than that of CE-MRA sequence ( P<0.05). ⑵ In the aspect of " observing the small vessels in the tumor" , CE-MRA, T 1WI and 3D-T 1WI sequences diagnosed as grade B1 were 8 cases (27.59%), 5 cases (17.24%) and 16 cases (55.17%), respectively. The diagnostic efficiency of 3D-T 1WI was better than that of T 1WI and CE-MRA ( P<0.05). ⑶ In the aspect of " observing the small vessels around the tumor" , CE-MRA, T 1WI and 3D-T 1WI sequences diagnosed as grade C1 were 18 cases(62.07%), 5 cases (17.24%) and 14 cases (48.28%) respectively. The diagnostic efficiency of CE-MRA and 3D-T 1WI wre better than that of T 1WI ( P<0.05). Conclusions:The combination of 3D-T 1WI and CE-MRA sequence can comprehensively evaluate the blood supply of the tumor, which is of great significance for the localization, characterization and treatment of brain tumors.
