Objective Alzheimer's disease(AD) is a common and devastating disease and there is no readily available biomarker to aid diagnosis or to monitor disease progression. This study is to further understand the pathogenesis of Alzheimer's disease and seek new biomarkers for AD. Methods AD rats made by Aβ1-40 were assessed using the Morris water maze method. Sera of two groups were collected and albumin, IgG and sodium chloride were removed from the serum before concentration. Two-dimensional electrophoresis(2-DE) was performed on serum protein. Altered proteins were identified by matrix assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS). Results Compared with untreated samples, 10 altered proteins were found through 2-DE and all of them were down-regulated of which 2 were identified by MALDI-TOF-MS to be plasma retinol-binding protein precursor and complement component 4, gene 2 (C4b). Conclusion C4b may be the biomarker of AD and it may be helpful to understand the pathogenesis of AD.

Objective To investigate the rationality and prognostic value of the Criteria for clinical staging of esophageal cancer treated by non-surgical methods (Draft) by comparison with the criteria for postoperative pathological staging.Methods A retrospective analysis was performed on the clinical data of 162 patients with esophageal cancer who underwent radical resection at the Second Hospital of Soochow University from December 2008 to July 2012.Preoperative clinical staging and postoperative pathological staging were performed,and the Kappa statistic was used to evaluate the agreement between the two staging systems.The Kaplan-Meier method was used to calculate overall survival (OS) rates,and the log-rank test was used for survival difference analysis and univariate analysis.Results The coincidence rates of T,N,and TNM stages were 67.9％,57.4％,and 67.9％,respectively,and the agreements were moderate,poor,and moderate,with Kappa values of 0.544,0.302,and 0.509.The follow-up rate was 93.2％.The 1-,2-,and 3-year sample sizes were 127,66 and 27,respectively.The 1-,2-,and 3-year OS rates were 82.6％,56.2％,and 37.7％,respectively.There were no significant differences in OS between patients with preoperative T1 and T2 stages and between patients with preoperative N0 and N1 stages (P =0.086,0.101),but significant differences were observed between patients with different T stages,N stages,or TNM stages (P =0.000-0.028).This was in line with the prognostic results based on the postoperative pathological staging.Conclusions The clinical staging criteria (draft) have moderate agreement with the criteria for postoperative pathological staging and have good prognostic value,but they require further refinement and improvement.

The 23 cases with chronic myelogenousleukemia (CML) were treated with program ofharringtonine and ara-c (HA) and the results werethat the 13 cases got complete remission and 10cases got partial remission. Comparing with thecontrol group the patients of which were treatedwith busulfan, the authors found that the spendedtime of decreased WBC in blood (WBC decreasedto 10. 0 ? 10~9/L) and reduced spleen (reduced tosmallest status of spleen) and improvement of self-sensation symptoms in the group treated with HAwere better than those in control group. The HAprogram for cases who recured CML again and re-ceived maintenance cure after remission of CMLwas still effective. The time of maintenance cureand interval should be individualized.

Objective To study the characteristics and the related risk factors of coronary artery changes in the elderly patients of coronary heart disease complicated with diabetes mellitus. Methods According to WHO diagnostic standards of diabetes, coronary heart disease(CHD) complicated with diabetes mellitus(65 patients) was indicated as CHD+DM group, and the coronary heart disease without diabetes(68 patients) was indicated as CHD group. All patients were examined by coronary angiographic semiquantitative(CAG), and blood pressure, oral glucose tolerance test, level of blood sugar, insulin, lipid, BUN and Cr were measured. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis were evaluated by AHA standards. The related risk factors in coronary artery disease were analysed by pluralism straight line statistics. Results The coronary multivessel changes(75 4% vs 38 2%, P

BACKGROUND: Apoptosis of cardiomyocytes is speeded up during ischemic reperfused injury. Acupuncture on the points of hand- Jueyin meridian can inhibit the progression of reperfused injury and reduce apoptosis of cardiomyocytes so as to provide the protection on the heart.OBJECTIVE: To observe the effects of acupuncture on the points of hand-Jueyin meridian on apoptosis of cardiomyocytes during ischemic reperfused injury.DESIGN: Randomized controlled experiment based on the experimental animals.SETTING: Department of acupuncture and massage in a university of traditional Chinese medicine.MATERIALS: The experiment was performed in Central Laboratory of Shandong University of Traditional Chinese Medicine from April to December 2001. Forty Wistar male rats were employed, and were randomized into 5 groups, named as blank group, model group, "Neiguan(PC 6)" group,"Ximen(PC 4)" group and "Zhigou(TE 6)" group.METHODS: After electric acupuncture on the points of pericardium meridian for 20 minutes, the ligature was done on the anterior-descending branch of the left coronary artery for 40 minutes. Electrocardiogram (ECG) monitoring was followed. The ligature was released after electric acupuncture on the points for another 20 minutes and perfusion was restored for 60 minutes. Afterward, the heart was extracted, the cellular suspension was prepared and the determination with flow-type cell apparatus was applied.MAIN OUTCOME MEASURES: Effects of acupuncture on the changes in apoptosis rate of cardiomyocytes.RESULTS: In the model group, the typical apoptosis peak presented, the apoptosis rate was remarkably increased. The comparison between the points of pericardium meridian groups and the model group indicated very significant difference(P < 0.01) .The apoptosis rates in "Neiguan(PC 6)" group, "Ximen(PC 4)" group and "Zhigou(TE 6)" group as well as the model groupwere(4.29±0.76)%, (5. 17±0.88)%, (13.96 ±2.77)% and (16.01 ± 1.04)% respectively.CONCLUSION: Acupuncture on the points of hand-Jueyin meridian inhibits myocardial apoptosis effectively so as to reduce myocardial injury caused by cell apoptosis.

Objective To approach the treatment of open reduction and internal fixation with titanium plate of anatomic type was applied for calcaneua fracture involving talocalcaneal joint. Methods Twenty-eight patients (36 feet) were performed with open reduction and internal fixation with titanium plate of anatomic type from April 2004 to November 2007. The Bohler angle, the Gissane angle and the length, breadth, height of calcaneus were compared before and after operation. Results The patients were followed up in an average period of 20 months. All the patients were healed and their arches became normal. The average data of Bohler angle was 19.89°±1.28° after operation while -6.23°±0.35°before operation. The average height of calcaneus was (42.80±2.49) mm after operation while (36.10±2.38) mm before operation. Conclusions The treatment of open reduction and internal fixation with titanium plate of anatomic type is a kind of good method for calcaneus fracture involving talocalcaneal joint. It can not only resume the Bolder angle and the Gissane angle,but also resume the, breadth, height of calcaneus. As a result, it can achieve anatomical reduction and patients can do exercises as soon as possible.
