Objective To establish rat models with Alzheimer's disease(AD) induced by ?-amyloid,and to observe the effects of nicotine on learning and memorizing ability of the rats. Methods Aggregated A?1-40 was injected into the bilateral basal forebrain of the rats.Learning and memorizing ability of the rats were inspected through Morris water maze test.The effects of nicotine on learning and memorizing ability of the rats induced by ?-amyloid peptide were observed. Results The learning and memorizing ability of AD animal models injected aggregated(A?1-40) for 2 weeks decreased(P

Objective To explore role of functional neck dissection for lower collar-shaped incision at hair margin behind ear in the treatment of differentiated thyroid cancer. Methods The clinical data of 11 patients with thyroid papillary carcinoma who underwent func-tional neck dissection for lower collar-shaped incision at hair margin behind ear were retrospectively analyzed. Results The incisions of all patients were unseen in daily life and patients were satisfied with the postoperative appearances. No case of shoulder syndrome,postoperative local recurrence and distant metastasis was observed. Conclusion Functional neck dissection for lower collar-shaped incision at hair margin behind ear is effective in the treatment of differentiated thyroid cancer. Meanwhile it can obviously improve patients’ postoperative appearance and life quality,therefore it is worth clinical application.

OBJECTIVETo study the molecular mechanism of extracts from Euodia rutaecarpa on hepatotoxicity in mice.

METHODTotally 30 KM mice were divided into 3 groups and orally administrated extracts from E. rutaecarpa for consecutively 15 days. The expressions of Erkl/2, CDK8, CK1e, Stat3 and Src were detected by Western blotting method.

RESULTThe extracts from E. rutaecarpa could up-regulated Erkl/2, CDK8 and CK1e expressions (P <0.01) and down-regulate Stat3 and Src (P <0.01).

CONCLUSIONThe molecular mechanism of E. rutaecarpa on hepatotoxicity may be correlated with Erkl/2, CDK8, CKle, Stat3 and Src signal molecules.

Objective To explore the alterations of protein phosphatase-2A (PP-2A) in lymphocytes in mild cognition impairment (MCI) and Alzheimer's disease (AD).Methods The activity PP-2A of was measured by ~(32)p liquid seintillography for incorporated radioactivity in control group(n=11) , the MCI group(n=11),and the AD group(n=11).The expression of PP-2A was determined by Western blot.Results In the control group,the activity of PP-2A (1.01?0.09) and the expression of PP-2A (0.96?0.07) were high while in the MCI group,the activity of PP-2A (0.71?0.12) and the expression of PP-2A (0.80?0.05) were decreased (both P

Objective To invesgate the effect of P-glycoprotein(PGP)inhibitor,verapamil,on electrobiological activity and seizure behavior in phenytoin-carbamazepine(PHT-CBZ)resistant rats.Methods The model of medically intractable epilepsy was established by kindling of amygdale. Verapamil was applied to PHT-CBZ resistant rats,followed by the observation on after discharge threshold (ADT),after discharge duration(ADD)and seizure activity.Results Compared with the control group, the ADT was higher in PHT-CBZ resistant rats peritoneally injected with verapamil((238.0?32.2)?A vs (177.0?23.3)?A,P

The present residents training for ultrasound departments depends mostly on poorlyscheduled rotation and clinical clerkship,with repeated and obsolete subjects in their training.The authors identified these setbacks and such characteristics as complication of ultrasound medicine,complex and variable ultrasonic scan technique,and the high threshold for beginners.In view of this,the authors adopted the tutorial system training mode for cultivating the residents in their medical care,teaching,research and foreign language competencies.A questionnaire survey of 44 residents so trained evaluated outcomes of the mode,with constructive suggestions raised on expansion of the training base,improvement of teachers’competency and reduction of trainees' workload.

Objective To summarize the experience in hepatic artery reconstruction in adult-to-adult living donor liver transplantation(ALDLT).Methods Fifty patients underwent ALDLT in our hospital from January 2002 to July 2006.All the hepatic a~ery reconstructions were done under surgical microscope.ResultsTwo patients(4%)presented with hepatic artery thrombosis.All the patients were followed up for 2 to 52 months (median,9 months),and no hepatic artery stenosis nor hepatic artery pseudoaneurysm occurred.The 1-year survival rate was 92%(46/50).Conclusions Systematic evaluation of hepatic artery reconstruction and use of microsurgical technique are key to the reduction of complications of hepatic artery reconstruction in ALDLT.

Objective To investigate the effect of early enteral nutrition.Methods 248 patients with esophageal and gastric carcinoma were randomly divided into two groups,and received enteral nutrition(EN)and parenteral nutrition(PN)each continuously for 6 days after operation.The body weight,blood routine test,liver function,and postoperative day 8 were compared with those before operation.Results The body weight,red blood cell count,and the levels of hemoglobin,serum albumin and transaminase decreased less in EN group than those in PN group(P＜0.01).The complication rates of anastomotic fistula,pulmonary infection,and delayedincision healing and average volume of pleural effusion were 0,13.8%,0,780ml in EN groups,while 3.2%,28.2%,7.2%,1842ml in PN group.Conclusion Early postoperative enteral nutirtion after esophageal carcinoma surgery can improve nutritional status and reduce complications in comparision with parenteral nutrition.

Objective To explore the therapeutic effect of combining continuous venovenous hemofiltration (CVVH) with hemoperfusion (HP) on patients with septic shock.Methods A prospective study was conducted. Thirty-two patients with septic shock admitted to Changshu No.1 People's Hospital were enrolled, and they were divided into two groups according to random digits table. The observation group (17 cases) was given HP before CVVH, in the control group (15 cases), only CVVH treatment was carried out, and lasting for 5 days in both groups. The changes of pulse oxygen saturation (SpO2), central venous pressure (CVP), systemic vascular resistance index (SVRI), cardiac index (CI), extra-vascular lung water index (EVLWI) were observed before treatment and 5 days after treatment.Results Compared with those before treatment, the levels of SpO2, CVP, SVRI, CI were obviously elevated, and EVLWI was markedly decreased after treatment in two groups. Compared with those of control group, the degrees of improvement of above indicators in observation group were more prominent [SpO2: 0.966±0.035 vs. 0.939±0.036, CVP (mmHg, 1 mmHg = 0.133 kPa): 8.5±3.2 vs. 8.1±4.2, SVRI (kPa·s·L-1·m-2): 1 497.35±157.08 vs. 1 343.60±144.48, CI (mL·s-1·m-2): 120.36±15.34 vs. 106.69±12.33, EVLWI (mL/kg): 6.84±0.73 vs. 7.65±0.70, allP < 0.05].Conclusion Combing HP with CVVH for treatment of patients with septic shock can improve their prognosis more obviously than using CVVH alone.
