Based on the analysis of the necessity of the integration of the medical ethics education into basic medical morphology experiment teaching, this paper discussed the principles of appropriate and suitable integra-tion. In addition, it pointed out the measures to integrate the medical ethics education into basic medical morpholo-gy experiment teaching:integrating the revere life education with the teaching content, strengthening the death edu-cation, and giving full play to the teacher′s leading role.

To investigate the curative effect of needling bilateral points on apoplectic paralysis and preliminarily study the mechanism of its action, a treatment group of 41 patients was treated by needling bilateral points and a control group of 40 patients, by needling points on the affected side. The effect on apoplectic paralysis after 3 courses of treatment was significantly better in the treatment group than in the control group. Needling bilateral points can improve the curative effect.

ObjectiveTo observe the effects of lung resection surgery on left heart hemodynamics in elderly patients, and explore its correlation with postoperative arrhythmia.Methods The 16 elderly patients (age≥75 years) receiving lung resection surgery were selected. At the same time, 21 patients (age＜60 years) were selected as controls. The hemodynamic parameters of each patient were recorded at the time of preoperative (T1), surgery completion (T2) and first day after surgery (T3). For patients with arrhythmia during three days after operation, the parameters would be recorded before and after arrhythmia. Results There were no significant changes in heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), cardiac stroke volume ( SV),acceleration index (ACI), systemic vascular resistance (SVR) at T2 and T3 compared with T1 for both the two groups (P＞0. 05). Only the central venous pressure (CVP) increased at T2 compared with that at T1 [elderly group: (7.58±0.45) cm H2O vs. (5.92±0. 51) cm H2O, t=2.641, P＜0.01; control group: (7.49±0.34) cm H2O vs. (6.23±0.47) cm H2O, t=1.982, P＜0.05], while the CVP recovered to the preoperative level at T3. The incidence of arrhythmia was significantly higher in elderly group than in control group (31.3% vs. 14.3%, x2 = 4.26, P＜0.05), but there were no significant changes in the parameters before and after arrhythmia compared with those before surgery (P ＞ 0. 05 ).Conclusions The effects of pulmonary resection surgery on left heart hemodynamics in elderly patients can be avoided through full assessment preoperatively, heart-lung protection intraoperatively, as well as the correctly and timely clinical treatment and intensive care postoperatively. Pulmonary resection surgery has no effect on left heart hemodynamics even for patients with postoperative arrhythmia.

Sixty patients underwent surgery for malignant thoracic tumor were evenly randomized into control group (group A) and treatment group (group B).0.3 ml low-molecular-weight heparin was injected per 12 h for 3 d in group B from 24 h after surgery.Bilateral venous sonography of lower extremities were performed before and d1,d3 after operation.Blood coagulation marks PLT,PT,APTT,Fibrinogen (FIB)and D-dimer were determined at the same time.Diagnosis of calf vein thrombosis after surgery was confirmed by color Doppler sonography in 7 patients:1 in group B (3％) and 6 in group A (20％) (P ＜ 0.05 ).Thrombosis at calf intermuscular vein was found in 6 patients and thrombosis at posterior tibial vein in 1 patient.FIB and D-dimer had no significant difference on the dl ( P ＞ 0.05 ) between two groups,but significantly lower on the d3 after surgery in group B than that in group A ( P ＜ 0.05 ).Low-molecularweight heparin reduced blood hypercoagulation state and thrombosis.Color Doppler sonography can be a valuable method for detecting asymptomatic deep vein thrombosis in the early stage after surgery and monitoring the efficacy of thrombosis prevention.

Objective To study the relationship between Helicobacter pylori (Hp) DNA positive detection in bile of gallbladder and intragastric Hp's colony and its plausible mechanism.Methods Sixty patients of gallbladder innocence diseases were recruited in the case group and 30 health populations were recruited in the control group.13CPDB was used to detect the infection of Hp.The cytotoxin associated gene antigen (cagA) in gall and gall-stone were detected through PCR.The empty function was tested through B ultrasound.Results The infection rate of Hp in all cases is 50.0% (30/60) and 7 of 30 bile (23.3%) ,1 of 30 gallstones (3.3%) were positive for Hp cag-A by PCR analysis in positive Hp infection group,with none of the 30 bile were positive in negative group( x2 = 5.822 ,P ＜ 0.05 ).The contraction rate of gallbladder of Hp positive group ( 56.8 ± 17.1 ) %was lower than negetive group' s ( 69.4 ± 13.1 ) % and the control group' s (63.3 ± 17.1 ) % ( F = 5.633,P ＜0.05).Conclusions Hp DNA is present in bile of gallbladder,and is related with Hp infection in stomach.Impairment of the gallbladder empty function may be related with Hp infection.

BACKGROUND:Adipose-derived mesenchymal stem cels have rich sources that are easily obtained, which can be used to treat acute myocardial infarction. OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cel transplantation on acute myocardial infarction in rats. METHODS:Rat models of acute myocardial infarction were made and subjected to adipose-derived mesenchymal stem cel transplantation in comparison with model and control (sham operation) groups. RESULTS AND CONCLUSION:Echocardiography findings showed significant improvement in the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ejection fraction in the cel transplantation group compared with the model group (P < 0.05). Hematoxylin-eosin staining showed that myocardial infarction was evident in the model group, in which, there were rarely viable myocardial tissues and few vessels in the infarcted region, but in the cel transplantation group, there were evident survived myocardial tissues and transplanted cels. The percentage of infarct size was significantly lower in the cel transplantation group than the model group (P < 0.05). Immunohistochemical staining showed that adipose-derived mesenchymal stem cels were able to survive in the infarcted myocardial tissues, and the expression of cardiac troponin T in the cel transplantation group was significantly higher than that in the model group (P < 0.05). Experimental data show that adipose-derived mesenchymal stem cel transplantation can protect the myocardial tissues after myocardial infarction, and effectively improve the myocardial function.

Objective: To investigate the protective effects of different storage solutions on the ultrastructure and integrity of rabbit endothelial cells, and their effects on endothelin 1 secretion. Methods: Femoral artery segments were harvested from 16 adult rabbits, which were then stored separately in four different storage solutions. The solutions was: (1) verapamil nitroglycerin solution (VG); (2) heparinized papaverine autologous blood (PB); (3) papaverine solution (PS); (4) Ringer's solution (Ringer). The ultrastructure of the endothelial cells,the covering percentage of endothelium monolayer and the level of endothelin 1 secretion were evaluated. Results: The covering percentage of endothelium monolayer was significantly higher in VG [(69?10)%] and PB[(71?9)%] compared with that in Ringer [(55?11)%] (P0.05). The endothelial ultrastructure was more seriously damaged in PS than that in VG and in PB through TEM. The level of endothelin 1 secreting was similar significantly increased only in PB [(116.781?22.387) pg/ml] compared with that in Ringer (P

Objective To investigate the relationship of college students'explicit and implicit attitudes to suicide and the feasibility of applying B-IAT to measure their suicide attitude.Methods Explicit suicide attitude was primarily investigated by suicide attitude questionnaire (SAQ),and implicit attitudes experimental study was carried out by suicide brief implicit association test (B-IAT).The subjects of this study included 50 college students,and it was used within-subject design.Results ①Each dimension values of explicit suicide attitude was from 2.5 to 3.5,indicating that the subject~ explicit suicide attitude dominated by neutral or contradictory.②The mean of B-IAT was 0.43,indicating that the subjects' implicit suicide attitude was prone to negative.③College students' suicide explicit and implicit attitudes were statistically no significant correlation,indicating that students implicit suicide attitudes was independent of explicit attitudes.Conclusion It is feasible to measure explicit suicide attitudes by B-IAT.College students' implicit suicide attitudes is independent of explicit attitudes.The results from simple IAT may be more accurately reflects the subjects' true attitudes towards suicide.

Objective To study the pre-existing intimal hyperplasia and the expression of nuclear factor-κB (NF-κB) and vascular cell adhesion molecule 1 (VCAM-1) in great saphenous vein(GSV) among the patients with diabetes mellitus undergoing coronary artery bypass grafting(CABG).Methods Segments of GSV were collected from 20 patients with diabetes mellitus and 22 patients without diabetes mellitus undergoing CABG.Morphometric analysis was performed after hematoxylin-eosin (HE) staining and Masson staining by microscopic computer analysis.Immunohistochemistry staining was used to examine the expression of NF-κB and VCAM-1 in intima.Results Pre-existing intimal hyperplasia was more common and server in GSV of the patients with diabetes mellitus.The expression of NF-κB and VCAM-1 were significantly higher in intima of GSV in patients with diabetes mellitus than patients without diabetes mellitus.The expression of VCAM-1 was positively related to NFκB in intima of GSV.Conclusion The pre-existing intimal hyperplasia and the expression of NF-κB and VCAM-1 were more common and server in GSV of the patients with diabetes mellitus than patients without diabetes mellitus.This can partially explain the poor prognosis of patients with diabetes mellitus after CABG.

Objective: To observe the effect of the acupuncture plus medication on the expression of silent information regulator of transcription 1 (SIRT1) and transcription factor forkhead box protein O3a (FOXO3a) in the hippocampus, the malondialdehyde (MDA) content, and the superoxide dismutase (SOD) activity of rats with Alzheimer disease (AD), and to explore the possible mechanism of combining acupuncture and medication in improving AD-related neurological symptoms. Methods: Sixty male Sprague-Dawley rats were divided into a normal group, a model group, an electroacupuncture (EA) group, a drug group, and an acupuncture-medication combined group by the random number table method, with 12 rats in each group. The model was established by micro-injection of streptozotocin into the bilateral lateral ventricles. After successful modeling, rats in the EA group received EA at Zusanli (ST36) and Dazhui (GV14), those in the drug group received intragastric administration of resveratrol at a dose of 44 mg/(kg·bw), and those in the acupuncture- medication combined group received the combined intervention of EA and resveratrol. Rats in each group received intervention once a day for 4 consecutive weeks. Morris water maze was used to detect the rat behavioral changes. Nissl staining method was used to observe the cell morphology and changes in the number of rat hippocampal neurons. Western blotting and immunohistochemical staining methods were used to observe the expression changes of SIRT1 and FOXO3a. The thiobarbituric acid method was used to detect the MDA content. SOD activity was determined by the hydroxylamine method. Results: Compared with the normal group, the escape latency was significantly prolonged (P<0.05); the percentage of stay in the target quadrant was reduced (P<0.05), the hippocampal neuronal cells were shrunken, nucleoli were unclear, and cell number was reduced (P<0.05); the SIRT1 expression and SIRT1 positive cell number were decreased, while the FOXO3a expression and FOXO3a positive cell number were increased significantly (P<0.05); the MDA content was increased significantly, and the SOD activity was decreased significantly (P<0.05) in the model group. Compared with the model group, the escape latency was shortened (P<0.05); the percentage of stay in the target quadrant was increased (P<0.05); the shape and number of hippocampal neurons tended to be normal (P<0.05); the SIRT1 protein expression and the SIRT1 positive cell numbers were increased, the FOXO3a protein expression and the FOXO3a positive cell number were decreased (P<0.05); the MDA content was significantly decreased, and the SOD activity was significantly increased (P<0.05) in the EA group, the drug group, and the acupuncture-medication combined group. The changes in the acupuncture-medication combined group were more obvious (P<0.05). Conclusion: Both EA and resveratrol improve the learning and memory ability of AD rats by regulating the expression of SIRT1 and FOXO3a and improving the levels of MDA and SOD in the hippocampus and protect the hippocampal neurons, while the combined use of EA and medication is more effective than EA or resveratrol alone, suggesting that this combined treatment is more effective in AD treatment.
