Surgical treatment is an important method for the treatment of inflammatory bowel disease (IBD) when it is complicated with other intestinal diseases or medical treatment fails.The appropriate timing of surgery can reduce the incidence of postoperative complications and is the key factor for the success of treatment.Excessive emphasis on medication and blindly extending the course of medication in case of invalidation will make patients lose the best opportunity of surgery.Surgeons should master different surgical techniques of acute and selective surgeries for IBD.Multi-disciplinary treatment mode is recommended.Adjustment of the preoperative medication,improvement of the nutritional status and the overall condition of the patients are necessary when surgery is unavoidable.

Mitochondrial aldehyde dehydrogenase(ALDH2),one of the isoforms of aldehyde dehydrogenase,has multiple enzymatic functions including the activity of dehydrogenase and esterase.The metabolisms of ethanol,amino acids,biogenic amine,vitamin or steroid in the body produce various substances of aldehyde.With the help of co-factor NAD(P)+,ALDH2 can convert aldehydes into corresponding carboxylic acid,which plays a key role in reducing toxic effects of aldehydes on the body.It does not need co-factor when ALDH2 works as esterase.It can convert carboxylic ester or other acids into corresponding carboxylic acids or alcohols.Recently,it has been shown that the decrease of ALDH2 activity exacerbates multiple factors(such as ethanol,ischemia)-induced myocardial injury and accelerates the development of nitroglycerin tolerance.Therefore,the development of specific agonists of ALDH2 may provide a novel approach to the therapy and prevention of heart diseases.

In this paper the investigation of using a new method-ABC-ELISA in assay of Autoimmune Thyroid Disease are presented. The sensitivity of ABC-ELISA is compared with that of standard ELISA; Its reliability is proven by the methods of detecting TSAb with FRTL-5. TRAb is detected by ABC-ELISA in 91% of untreated Graves'. TRAb is detected by Standard ELISA in 70% of untreated Graves'. The results of ABC-ELISA in 26 untreated Graves' are equal to that of the method of detecting TSAb with FRTL-5. Therefore, we consider that ABC-ELISA is a sensitive, reproducible, convenient method applicable to clinical practice.

Objective: To investigate the expression of nuclear factor-κB (NF-κB) subunits P50 and c-Rel protein in primary cortical neurons of Wistar rats at different time points of oxygen glucose deprivation/ reoxygenation(OGD/R). Methods: The neurons dissociated from the cortex of the neonatal rats were primary cultured and were identified by immunocytochemistry. OGD/R model was established. The study was divided into 6 groups according to different processing methods,including normal group,OGD 4 h treated,OGD 4 h/R 2 h treated,OGD 4 h/R 6 h treated,OGD 4 h/R 12 h treated and OGD 4 h/R 24 h treated groups. The expression of NF-κB P50 and c-Rel protein in neurons was examined by immunocytochemistry method and Western blotting. Results: (1) Immunocytochemistry detection targeting neuron specific enolase (NSE) and beta-III tubulin confirmed that the cultured cells were neurons. (2) The expression of NF-κB P50 protein was significantly higher in OGD 4 h group than in control group(P<0.05); the expression continued to increase in OGD 4 h/R 2 h andOGD 4 h/R 6 h groups, and reached its peak 6 h after reoxygenation (P<0.01),then began to decrease,but the expression in OGD 4 h/R 12 h group was significantly different from that of the control group (P<0.05); there was no significant difference between OGD 4 h/R 24 h group and control group. (3) The expression of NF-κB c-Rel protein was similar between OGD 4 h group and the control group; the expression increased in OGD 4 h/R 2 h and OGD 4 h/R 12 h groups and reached its peak 12 h after reoxygenation(P<0.01),and did not recover to the normal level in OGD 4 h/ R 24 h group (P<0.05). Conclusion: Oxygen glucose deprivation/reoxygenation can activate NF-κB subunits P50 and c-Rel in the primary cortical neurons in rats in a time-associated manner.

Objective To explore the relationships between cholangiocarcinoma and clonorochiasis or hepatolithiasis,and to compare their MRI features.Methods The MRI features in 37 patients with cholangiocarcinoma confirmed by surgery and pathology were retrospectively analyzed,including clonorchiasis with cholangiocarcinoma in 21 (group A)and hepatolithiasis with this tumor in 16 (group B).The analyzed parameters included the location,size,shape,signal intensity and enhancement pattern of the tumor and the characteristics of bile duct dilatation.Results In group A,the tumors were located in the right lobe in 12 (57.2%),left lobe in 4 (19%),and porta hepatic in 5 (23.8%).In group B,those were located in the right lobe in 3 (18.7%),left lobe in 9 (56.3%),and porta hepatic in 4 (25%).There was a significant difference in the left/right lobe between two groups (P<0.05),however,no significant difference was found in porta hepatic (P>0.05).The MRI showed the tumors with low signal on T1 WI and high or heterogeneous signal on T2 WI,and with peripheral enhancement in early stage and delayed centric enhancement in 34 patients.Diffuse saccular dilatations of terminal intrahepatic bile ducts were showed in 1 6 (7 6 .2%)in group A and 1 (6 .2%)in group B,meanwhile the dilatations of bile ducts within tumors were showed in 2 (9.5%)in group A and 13 (81.3%)in group B,exhibiting significant differences between the two groups (P<0.05).Conclusion Clonorochiasis and hepatolithiasis are related with the cholangiocarcinoma.No differences in MRI features of cholangiocarcinoma are found between the two groups,however significant differences in location and the features of bile duct dilatation are observed.

Objective To evaluate the clinical feasibility and safety of percutaneous transluminal coronary thrombolysis in acute myocardial infarction. Methods Consecutive patients( n =25) with evidence of AMI and thrombolysis in myocardial infarction(TIMI) grade 0 or 1 in the infarction related arteries(IRA) underwent coronary ultrasound thrombolysis. Degree of residual stenosis was measured and analyzed with SHIMADZU Digitex, a 2400 computerized analyzing system. Changes in imaging and blood flow in IRA, CK MB before and after the treatment, ST segment in ECG and clinical manifestations were observed to evaluate the feasibility of using angioplasty with ultrasound to treat AMI. Results It was found that IRA achieved grade Ⅲ of TIMI blood flow in 23 out of the 25 patients with AMI (potency recovering rate=92%) and the residual stenosis was 41.39?14.08%. Within 10 minutes after the treatment, disappearance of chest pain, depression of ST segment more than or equal to 50% and obvious migrating forward of CK MB peak value were found in the 23 patients. There were no adverse clinical events during the procedure and hospitalization. Conclusion Angioplasty with high intensity, low frequency ultrasound can be used as a new approach for treating acute myocardial infarction, opening IRA as early as possible and restoring TIMI blood flow grade Ⅲ.
