Objective To determine the influence of general anesthesia on postoperative cognitive function in patients undergoing noncardiac surgery. Methods Forty ASA Ⅰ -Ⅱ patients aged 50-70 years undergoing elective noncardiac surgery under general anesthesia ( n = 20) or general anesthesia combined with epidural block (n =20) were studied.Patients with psychiatrical or neurological disorders or taking hyponotics regularly were excluded.General anesthesia was induced with propofol 1.5-2.5mg/kg and fentanyl 2?g/kg.Tracheal or bronchial intubation was facilitated with vecuronium 0.6mg/kg.The patients were then mechanically ventilated and PETCO2 was maintained at 30-40mm Hg. Anesthesia was maintained with 1.0%-2.0% isoflurane and intermittent iv boluses of vecuronium. Epidural catheter was inserted at T8.9 and a mixture of 0.33% poutocaine and 2%lidocaine was infused through catheter at a rate of 4-6ml/h by using Graseby 3500 infusion pump.Radial artery was cannulated for intra-arterial pressure monitoring. ECG, PETCO2 and end-tidal-isoflurane concentration were monitored during operation. Whenever BP was

Purpose To analyze retrospectively the clinicopahological characteristics and immuophenotype in 120 cases of pulmonary selerosing hemangioma ( PSH) . Methods Data of 120 cases of PSH were collected and reviewed, including gross features and frozen diagnosis, histopathological features, morphology in HE and immunohistochemical characteristics of tumor cells. Results PSH pres-ents a well-circumscribed mass with a sense of expansion after cutting, which showed a solid, grey to tan-yellow surface with foci of haemorrhage. Two kinds of tumor cells and four typical patterns with mixed forms, are often shown under light microscope (92/120, 76. 67%). Focal accumulation of histocytes and scattered mast cells were noted in some cases (83/120, 69. 17%). Both surface cells and round cells were TTF-1 and EMA positive. Surface cells expressed SP-A, CK and NapsinA. Round cells expressed vimentin. Conclusion Gross features and typical“two cell types, four patterns” contribute to PSH diagnosis. Meanwhile, foal accumulation of foam histocytes and scattered mast cells show a clue to PSH diagnosis and differential diagnosis.

ObjectiveTo study the change of autophagy of human pancreatic cancer cell MiaPaCa-2 before and after Ad5-KAI1 tranfection,and to investigate the possible mechanism.MethodsThe MiaPaCa-2 cells without KAI1 expression were infected with Ad5-KAI1 with KAI1 target gene,and Ad5-null was used as negative control,and parental cell was used as blank control.The formation of autophagosomes was observed by electromicroscopy.The green fluorescent protein-labeled light chain 3 (LC3) associations with autophagosome membranes was detected by confocal microscopy.PD98059,LY294002 were applied to pre-treat the cells.The expression levels of beclin 1,AKT,ERK,the phosphorylation of AKT and ERK protein and the ratio of LC3-Ⅱ to LC3- Ⅰ were detected by Western blotting.ResultsAfter 100 MOI Ad5-KAI1 infections for 24 h,the rate of cell expressing KAI1 protein reached (84.97 ±8.56)％,number of LC3 increased from 4 to 20; and swelling,degeneration of mitochondria was observed,and bilayer-like structure in cytoplasm was found.The expression of beclinl increased (1.4 ±0.3 ) folds,and the expression of LC3-Ⅱ/LC3- Ⅰ increased (8.00 ±2.78) folds.PI3K blockade LY294002 pretreatment significantly suppressed the phosphorylation of AKT of MiaPaCa-2 (2.756 vs 1.516),but it did not inhibit the increase of ratio of LC3-Ⅱ to LC3- Ⅰ(0.770 vs 1.403).ERK blockade PD98059 pretreatment not only significantly suppressed the phosphorylation of ERK of MiaPaCa-2 ( 1.637 vs 0.403 ),but also inhibit the up-regulation of beclin 1 protein expression ( 2.377 vs 1.150) and increase of ratio of LC3- Ⅱ to LC3- Ⅰ (2.225 vs 0.680).ConclusionsKAI1 can significantly induce autophagy of human pancreatic cell line MiaPaCa-2 through phosphorylation of ERK rather than AKT.

Objective To explore the pathway of KAI1 induced autophagy regulating apoptosis in human pancreatic cancer cell line MiaPaCa-2.Methods There were three groups in the experiment,which were extracellular regulated protein kinases (ERK) phosphorylation inhibitor PD98059 pretreated group,Caspase-3 activation inhibitor VAD-FMK pretreated group and no PD98059 or VAD-FMK pretreated groups.And each group was divided into three sub groups with different treatment,which were adenovirus AD5-null vector infected control group,the human KAI1 gene recombinant adenovirus vector AD5 KAI1 infected group and autophagy inhibitor 3-MA pretreated and AD5-KAI1 infected group.The cell apoptosis was observed by AnnexinV-FITC/PI double staining.Caspase-3 activation level was evaluated by flow cytometry.ERK phosphorylation and poly(ADPribose) polymerase (PARP) cleavage were determined by Western blot.Results After the cancer cells infected with AD5 KAI1,KAI1 protein was expressed and GFP-LC3 green particles increased.Caspase-3 activation,PARP cleavage,ERK phosphorylation and apoptosis increased obviously.After autophagy inhibitor 3-MA pretreated,the percentage of apoptosis increased from (63.0 ± 7.9)％ to (88.0±4.5) ％ and Caspase-3 activation increased from (34.0±2.8) ％ to (44.2±4.0) ％ and PARP cleavage more.The apoptosis induced by 3-MA could be totally inhibited by Caspase-3 activation inhibitor VAD-FMK pretreated but could not be inhibited by ERK phosphorylation inhibitor PD98059.Conclusion KAI1- induced autophagy inhibits apoptosis through the downregulation of Caspase-3activation and PARP cleavage instead of ERK phosphorylation.

Medical Image has been increasingly applied in clinical diagnosis and treatment.It is very important to make use of large numbers of images in medical image management system in order to help clinician to analyze and diagnose.The traditional information retrieval techniques are not fit for retrieving large scale medical image databases.It is a very promising idea to introduce Content-based Image Retrieval(CBIR) technique into indexing medical image databases.The structure of the Content-based Medical Image Retrieval System(CBMIR) is introduced,and the key problems are mainly investigated,which included image segmentation,feature extraction,similarity searching and feedback mechanism.At last,the status and development of CBMIR are discussed.

ObjectiveTo observe cluster needling of scalp acupuncture combined with rehabilitation(Tang's Approach) as an early intervention for the children with high-risk of cerebral palsy.Methods62 infants with high-risk of cerebral palsy in hospital from Jan. 2006 to Dec. 2008 were divided into the acupuncture with rehabilitation group and rehabilitation group. The scores of Mental Develop Mental Index (MDI) and Psycho-Motor Developmental Index (PDI) were assessed before and 3 months after the treatment. ResultsThe scores of MDI and PDI were better in acupuncture with rehabilitation group than in the rehabilitation group 3 months after the treatment (P＜0.01). There were significant differences in reducing dysfunction in the acupuncture with rehabilitation group compared with the rehabilitation group (P＜0.01). The follow-up result showed that there were certain advantages in reducing incidence of cerebral palsy by the acupuncture combined with rehabilitation. ConclusionAs an early intervention, Tang's Approach can improve motor function in children with high-risk cerebral palsy.

Objective To investigate the correlation of serum periostin and severe degree of dilated cardiomyopathy(DCM) in children.Methods Thirty-two children with DCM from Jan.2009 to Jun.2013 in First Hospital Affiliated to Jilin University were selected as DCM group.Then these children were divided into 0-2 score group (n =6),3-6 score group (n =7),7-9 score group (n =11),and 10-12 score group (n =8) according to Ross standardization.Twenty healthy children in the same period were selected as control group.Meanwhile,the levels of serum periostin were detected by using enzyme-linked immunosorbent assay,the levels of serum creatine kinase-MB(CK-MB)were detected by adopting immunosuppressive method,while left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were observed by using uhrasonography.The data in various groups were compared and the relationship between serum periostin and ROSS,LVEF was analyzed by performing linear regression analysis.Results 1.Compared with control group,the level of serum periostin in DCM group was significantly increased,and the difference was significant (P =0.00).The serum periostin level increased with the increase of ROSS score increase,and there were significant differences among the different ROSS score groups (all P ＜ 0.05).2.Compared with control group,the level of serum CK-MB in DCM group was significantly increased,the difference was significant (P =0.00) ;while the serum CK-MB levels had no significant difference among the different ROSS score groups(all P＞0.05).3.Compared with control group,the level of LVEF in DCM group was significantly decreased,the differences was significantly(P =0.00) ; and the LVEF level decreased with the ROSS score increase,there were significant differences among the different ROSS score groups(all P ＜ 0.05).4.Compared with control group,the level of LVEDD in DCM group was significantly enlarged,and the difference was significant(P =0.00) ; but the LVEDD had no significant differences among the different ROSS score groups (all P ＞ 0.05).5.Significantly positive correlation was found between the level of serum periostin and ROSS score (r =0.742,P ＜ 0.001).There was no obvious correlation between the level of serum periostin and CK-MB(r =0.247,P ＞ 0.05).There was negative correlation between the level of serum periostin and LVEF (r =-0.424,P ＜ 0.01).Conclusions The level of serum periostin is positively correlated with ROSS score and has negative correlation with LVEF.It may provide a useful index in the assessment of symptomatic state in children with dilated cardiomyopathy.

Objective To explore the preventive effect of Bailing capsules(BL) on myocardial fibrosis in the viral myocarditis(VMC) mice models and to clarify the possible mechanism.Methods The models of VMC were established by injecting Coxsackie virus B3 (CVB3) solution into 50 BALA/C mice.The 31 mice were divided into model group(n =11),large dose BL group(n =10)and small dose BL group (n =10).At the same time the control group (n =10) was established.The mice in model group and control group were fed with water 1 mL/d,the mice in large dose BL group were fed with BL at a dose of 7.5 g/(kg · d),and the mice in small dose BL group were fed with BL at a dose of 2.5 g/(kg · d).After 60 d,the levels of angiotensin Ⅱ (Ang Ⅱ) in blood serum of mice in various groups were detected by using ELISA.Myocardium tissue of mice was stained by Masson and collagen volume fraction(CVF)was accounted.At the same time,the content of periostin mRNA and transforming growth factor β1 (TGF-[β1) mRNA in myocardium tissue of mice were detected by adopting reverse transcription(RT)-PCR.Results Compared with the control group,the levels of serum Ang Ⅱ,CVF,TGF-β1 mRNA and periostin mRNA were increased (all P ＜ 0.01) in the model group.Compared with the model group,the levels of serum Ang Ⅱ,CVF and TGF-β1 mRNA were obviously decreased in large dose BL group and small dose BL group (all P ＜ 0.05).Compared with the model group,the level of periostin mRNA was obviously decreased in large dose BL group (P ＜ 0.05),but the level of periostin mRNA in small dose BL group was not decreased obviously (P ＞ 0.05).Conclusions BL can offer some protection to myocardial fibrosis in VMC mice.The possible mechanism may be performed through inhibiting the expression of serum Ang Ⅱ and TGF-β1 in myocardium tissue to reduce the expression of periostin.
