The emphasis and basic target of medical education is to cultivate medical students with high qualities. The qualities of medical students include professional ethics, self-cultivation, medical knowledge and physical-psychological quality, which is critical to the medical education. It has been proven that the teaching of Clinical Pathway is one of the most important factors to promote the improvement of comprehensive qualities of medical students.

Ophthalmology is a clinical course which requires students to have practical skills. The traditional clinical teaching method lacks varied means resulting in unsatisfactory teaching effects. Application of multimedia technology not only changes the teaching model, enriches the teaching contents but also improves the quality of ophthalmology teaching. By analyzing the advantages and disadvantages of multimedia application in clinical teaching based on our practice, the paper raises some methods for improvment in order to achieve the best teaching effects.

3) in control group (χ2=5.42,P=0.02).Conclusions Gemcitabine chemotherapy combined with HIFU treatment was more effective for pancreatic tumor growth control and pain relief without more adverse events,which was effective and safe.

Chinese medicinal formulae( CMF) were often used in the clinics of traditional Chinese medicine (TCM) which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. In current studies, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were often neglected. Thus, we put forward integrative pharmacology, which could integrate the correlation between CMF and biological organisms from multi-levels and multi-dimensional views. Integrative pharmacology would reveal the molecular mechanism of CMF for ailments treatment and screen out effective material systematically, which would be the new paradigm of TCM research.

Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P ＞ 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P ＜ 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P ＜0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To investigate roles of superoxide dismutase-1(SOD1),phosphatidylinositol 3-kinase (PI3K) /serine/ threonine protein kinase (AKT) signal transduction pathway in protection of propofol on spinal cord ischemic reperfusion injury (SCIRI) in rabbit model before and after ischemia. Methods Sixty Japanese male rabbits were randomly divided into 3 groups (n=20),namely sham-operation group (Group S),ischemia-reperfusion group (Group I/ R) and ischemia-reperfusion group with propofol treatment (Group P). Abdominal aorta of the rabbits in group I/ R and group P were blocked by clamp for 40 min and then the clamp was removed. Propofol (30 mg·kg-1 ) was intravenously infused 10 min before blocking the aorta and at the time of reperfusion. Normal saline was intravenously infused at the same time points in the other two groups. Four rabbits of each group were randomly executed 1,2,3,5,7 days after surgery. Spinal cord tissues at L3-L4 levles were harvested. Bioactivity of SOD1 was detected by ELISA and mRNA expression levels of SOD1,PI3K and AKT were detected by RT-PCR. Results On the 1st day after the surgery,the bioactivity of SOD1 increased significantly in Group I/ R and Group P as compared with that in Group S (P<0. 05). On the 2nd day,compared with Group S,the bioactivity of SOD1 increased significantly in Group P (P<0. 05),but there was no change in Group I/ R (P>0. 05). On the 3rd,the 5th and the 7th day,compared with Group S,the bioactivity of SOD1 decreased significantly in Group I/ R (P<0. 05),but there was no change in Group P (P>0. 05). Linear regression analysis indicated that there was a positive correlation between the changes of SOD1 activity and the mRNA expression of SOD1,PI3K and AKT respectively in spinal cord tissues. Conclusion Pre- and post-ischemic conditioning with propofol shows potent protective effects against SCIRI in the rabbit model. The mechanisms may be related to increased expression of SOD1 in the spinal cord tissues by activating PI3K/ AKT signal transduction pathway.

To study the expression of human telomerase RNA(hTR) in different grades of bladder transitional cell carcinoma and its relation to its prognosis. With in situ hybridization, the expression of hTR was observed in 67 cases of bladder transitional cell carcinoma specimens, to be compared with specimens of 10 normal bladder tissue and 10 benign lesions. The RNA probe used in hybridization was telomerase reverse transcript (TERT), and the marker was digoxin. There was a significent correlation between the expression of hTR and grading and prognosis. hTR is considered as an important and independent prognostic factor in this carcinoma.

Objective To explore the diagnostic value of Holter monitoring for coronary heart disease (CHD) in diabetic and non-diabetic patients. Methods 188 patients with coronary heart disease were divided into diabetic group(n=65)and non-diabetic group(n=123). The diagnostic sensitivity, specificity, accuracy and other indices of Holter monitoring for CHD were compared between the two groups according to the results of angiography and Holter monitoring. Logistic regression analysis was applied to analyze the factors affecting holter ST-segment change. Results The sensitivity of Holter monitoring for diagnosing CHD in diabetic group was higher than that in non-diabetic group(P=0.046). There was an association between the positive ST-segment change and number of stenosal arteries, diffuse arterial lesion and complete vessel occlusion respectively (OR=2.36, 4.91, 3.90). Conclusion Although the sensitivity and specificity of Holter monitoring for diagnosing coronary heart disease were low, it remains some diagnostic value for coronary heart disease in diabetic patients.
