Acute respiratory distress syndrome is one of the common respiratory diseases in neonates. It is more common in neonates by elective cesarean section.The pathogenesis is complicated, while delayed lung fluid clearance is considered playing a role in it.Meconium aspiration, delayed establishment of respiratory reflex, gestational age, contractions before onset, male baby,perinatal asphyxia,maternal diabetes or asthma are thought to be risk factors.

Concluded from the research,the main stream of current medical university students'concept of honor and disgrace is positive,including correct political conviction and good outlook on life.However,at the same time there also exist some negative aspects,such as wrong ideas on world outlook,value concept,moral concept and legal outlook.The negligence of school education and the negative influence of social environment are the main reasons.

Current researches have provided theoretical basis.Problems in life education and the corresponding strategies are proposed to boost the quality of life education.

Objective: To summarize the major ultrasonic manifestations of various hepatic vascular anomaly(HVA), so as to improve the ultrasonic diagnosis rate of HVA. Methods: The chief complaints, timing and mode of ultrasonic diagnosis of 18 patients with congenital HVA or post-liver transplantation HVA were retrospectively analyzed. Six of the 18 patients were subjected to detailed analysis. The major ultrasonic manifestations of various HVA were observed and experience of ultrasonic diagnosis was summarized. Results: The major vascular abnormalities in our group included hepatic vascular fistula (including fistulas between artery and vein, artery and portal vein, portal vein and hepatic vein, also a complex fistula among artery, portal vein and hepatic vein), portal aneurysm, congenital portal atresia and portal vein cavernous transformation; among which the portal atresia and the complex hepatic fistula involving hepatic artery, hepatic vein and portal vein were rarely described in the literature. Color Doppler ultrasound was the first choice for detection and diagnosis of HVA; contrast-enhanced ultrasound was sensitive and specific in diagnosis of all vascular fistulas due to its ability to display homodynamic phase. Conclusion: The wide application of Doppler and contrast-enhanced ultrasound examination improves the detection and diagnosis of HVA; diagnosis should be made based on scientific diagnosis mode and precise diagnosis planning.

Damaged articular cartilage has a limited intrinsic capacity to heal itself,especially in adults,It represents a clinical challenge.Novel gene therapy can introduce particular beneficial gene into the seeded sells and express growth factors or other therapy proteins at the repair site.Gene therapy focuses on selecting proper gene,target cells and the transferring systems. The tissue engineering cartilage with gene-modified seeding cells and transferring objective gene to target sells locally present new therapeutic regimens for repairing defects in articular cartilage.

Cartilage lesions resulting from acute or chronic injury are one of the major factors leading to joint disease and disability ,and eventually osteoarthritis. It is well known that articular cartilage in adults has a limited ability for self-repair,and represent a clinical management challenge. Numerous methods have been devised to augment its natural healing response. The most appropriate treatment option for an individual patient should be based on the pathologic characteristics of the lesion and the patient's symptoms, age and expectations. This review presents the current articular cartilage management and the direction in future therapeutic regimens.

Along with the "Two Meeting in 2006" convening,medical ethics construction has attracted people's attention again.I think the medical ethics construction should be ensured from its headstream,in other words,we should enhance the medical ethics education of medical students.It is very necessity to enhance the medical ethics education for the development of chinese traditional medical student,whether from the social expect,medical ethics education or from the study character of chinese traditional medicine.The end for medical ethics education is to develop medical students into doctors having mercy heart,noble soul,honest manner and polish technigue.And we should dewelop students from study of books,experient of practice and influence of culture.

Objective To investigate the protective effect of fenasinel dihydrochloride (FD) against stroke in stroke-prone spontaneously hypertensive rats (SHRSP). Methods Seven-week old male SHRSP were fed with NaCl 1g/d to induce stroke. Meanwhile, FD was injected intraperitcmeally at 1, 3, and 10 mg/(kg • d). The stroke onset time, Survival period after stroke, and neuronic deficit score after stroke were observed. Results FD delayed the onset of stroke n SHRSP and prolonged the Survival of the animals. Furthermore, low and medium doses FD also improved the Neuronal deficit score after stroke. Conclusion Our data suggest that FD has protective effect in SHRSP.

OBJECTIVE: To establish and compare the HPLC fingerprints of different medicinal parts of Morus alba. METHODS: An HPLC analysis was performed on an Agilent Eclipse XDB C18 (4. 6 mm × 250 mm, 5 μm) chromatographic column, using gradient elution with acetonitrile and 0.1% aqueous formic acid at a flow rate of 1.0 mL·min-1. The column temperature was kept at 30 ℃, and the detection wavelength was set at 254 nm. The data was analyzed with Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (Version 2004A). RESULTS: The HPLC fingerprints and common models of different medicinal parts of M. alba were established. The numbers of common peaks obtained in the fingerprints of Mori Cortex, Mori Ramulus, Mori folium, and Mori Fructus were 10, 11, 12, and 8, respectively. Ten characteristic peaks were identified by comparison with the reference substances and accurate molecular weights determined by UPLC-Q-TOF/MS. Mori Cortex and Mori Ramulus both had mulberroside A, oxyresveratrol, kuwanon G, and morusin. Rutin and isoquercitrin were detected in both Mori folium and Mori Fructus. CONCLUSION: The method is stable, reliable, and repeatable. The composition profiles of different medicinal parts are established, which provides a scientific basis for the quality control of M. alba.
