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.

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.

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 understand the occurrence and risk factors of healthcare-associated infection(HAI) in a neonatal intensive care unit(NICU).Methods Neonates who were admitted to the NICU of a hospital from January 2012 to December 2014 were investigated retrospectively,risk factors for HAI were performed univariate analysis.Results A total of 760 neonates were included in the investigation,198 neonates developed 259 times of HAI,incidence of HAI was 26.05％,case incidence of HAI was 34.08％,incidence of HAI per 1 000 patient days was 9.50‰;the main infection site was lower respiratory tract (n =92,35.52％);among 259 cases of HAI,172 strains of pathogenic bacteria were isolated,the major pathogen was Acinetobacter spp.(n =40,23.26％);incidence of HAI was high in neonates with gestational age ≤32 weeks,birth weight≤1 500 g,length of hospital stay ≥10 days,duration of antimicrobial use≥10 days,mechanical ventilation,deep venous catheterization,and feeding intolerance,difference was statistically significant (all P＜0.001).Conclusion Incidence of HAI in NICU is high,effective prevention and control measures should be formulated according to its risk factors,so as to reduce the occurrence of HAI in neonates.

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.

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.

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.

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.
