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.

Cor pulmonale is a common disease. The intervention varies and the effectiveness remains unsatisfactory. The vasodilators have been studied intensively in recent years and their application in treating the disease has been developing quickly. In this paper, the advances of research on the vasodilators in treatment of pulmonary hypertension in the last 5 years is reviewed, the advantages and disadvantages of the drugs presented, and a discussion on the trend of treatment of pulmonary hypertension made.

The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research.And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract.Currently, many ultrasonic methods and optical methods are used in measuring lens thickness.The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper.Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan.More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation.Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.

Objective To study the risk factors for catheter-related bloodstream infection (CRBSI)in an intensive care unit (ICU),and provide scientific evidence for CRBSI prevention and control.Methods 1 677 ICU patients with central venous catheterization (CVC)for>48 hours between January 2008 and December 2012 were divided in-to CRBSI group and non-CRBSI group,risk factors for CRBSI were analyzed.Results The utilization rate of CVC was 92.88% (21 041 d);86 (5.13%)patients developed CRBSI,the incidence of CRBSI per 1 000 catheterization-day was 4.02,the mortality of CRBSI group was significantly higher than non-CRBSI group (58.14% [50/86]vs 36.83%[586/1 591])(χ2 =15.74,P <0.01 ).Multivariate logistic regression analysis showed that the risk factors for CRBSI in-cluded length of stay in ICU>5 days,CVC>5 days,the episode of CVC>1 (P <0.01).Conclusion Realizing the occur-rence status and risk factors of CRBSI in ICU patients can provide reference for further targeted monitor and implementation of zero tolerance goal of the CRBSI.

Objective To investigate the effects of hypothermia combined with sevoflurane on myocardial monophasic action potential (MAP) and transmural dispersion of repolarization (TDR) of the left ventricle in rabbits in vitro. Methods Adult rabbits weighing 1.5-2.0 kg were sacrificed after heparinized and anesthetized.The hearts were immediately removed and perfused with K-H soluation saturated with 95%O2-5%CO2 at 37℃ in a Langendorff apparatus. Forty-eight isolated hearts were randomly divided into 6 groups ( n = 8 each): Ⅰ control group (group C), Ⅱ low concentration sevoflurane group ( group S1 ), Ⅲ high concentration sevoflurane group (group S2 ), Ⅳ hypothermia group (group H), Ⅴ hypothermia + low concentration sevoflurane (group HS1 ) and Ⅵ hypothermia + high concentraion sevoflurane (group HS2 ).Group C received continous perfusion. Group S1and S2 received perfusion with K-H solution saturated with 2.4% and 4.8% sevoflurane at 37 ℃ for 30 min respectively. Group H received perfusion with K-H solution at 30℃ for 30 min. Group HS1 and HS2 received perfusion with K-H solution saturated with 2.4% and 4.8% sevoflurane at 30℃ respectively.MAPs of epicardium, mid-myocardium and endocardium of the left ventricle were recorded. MAP duration at 90%repolarization(MAPD90)and TDR were calculated. Early after-depolarization,delayed after-depolarization and arrhythmia were also recorded. Results Compared with group C, MAPD90 of the 3 layers of ventricle was significandy prolonged, the incidence of arrhythmia increased in group H (P＜0.05). There was no significant difference in TDR among all groups ( P＞0.05). There was no interaction between sevoflurane and hypothermia (P＞0.05), and it only showed that MAPD90 was prolonged by hypothermia (P ＜0.05 ). Conclusion Hypothermia combined with sevoflurane exerts no significant effects on myocardial MAP and TDR of ventricles in rabbits, and sevoflurane decreases the incidence of hypothermia-induced arrhythmia through inhibiting the prolongation of MAPD90.

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.
