Objective: To establish a method of HPLC for determination of chlorogenic acid and baicalin in Yinhuang Oral Liquid (Flos lonicerae, Radix Scutellariae). Methods: LUNA C18(2) column was used. The acetonitrile 0.1% phosphoric acid solution was used as the mobile phase. The flow rate was 1.0mL?min -1 . The detection wavelength was set as 318nm. Results: For chlorogenic acid, the linear range was 0.2568 ～ 2.0544 ?g, and the average recovery rate was 97.7% with RSD =0.8%. For baicalin, the linear range was 0.9896 ～7.9168?g, and the average recovery rate was 98.0% with RSD =0.9%. Conclusion: The method is simple, reliable, accurate and can be applied to the quality control of the preparation.

Customized management based on chemotherapy initiated a new era in the treatment of retinoblastoma(RB).Many domestic ophthalmic centers are making beneficial attempts in this domain.However,the understanding of the trend needs to be improved throughout the country.In this article,a brief comment in five aspects is done in order to break the obsolete opinion and generalize the international classification of RB;correct some misunderstandings;promote an awareness campaign for early diagnosis;enhance the multi-center cooperation to improve the quality of clinical studies and start clinical and experimental research on RB.

Retinoblastoma is the most common intraoeular malignant tumor in children.In its treatment,drug therapy is one of the most effective and irreplaceable methods.To reduce the toxicity of drugs,enhance the therapeutic effect and lessen drug resistance, some new drug deliver systems and new medicines for retinoblastoma are coming into being.Ophthalmic arterial infusion,fibrin sealant and iontophoresis are newly-found drug deliver systems.And the latest drugs under research include nutlins,phenoxazine derivative Phx-1,combretastatin A4 phosphate,2-deoxy-d-glucose and histone deacetylase inhibitors,etc.The following text is focused on the two aspects of the drug therapy for retinoblastoma.

Objective To investigate the changes of brain angiography in patients with virus encephalitis.Methods Examining 5 patients with herpes simplex virus encephalitis and 2 patients with Epstein-Barr(EB)virus encephalitis by digital subtractiona angiography(DSA)system and compares the results with control group(including 10 headache patients).Results The results of DSA of virus encephalitis patients were all abnormal,the outcome was accelerating blood circle like irritation.The average of the whole time of brain artery and vein circle was 6.71 seconds,while the results of DSA examination of the control group were all normal,the whole time of brain circle was 10.25 seconds.There was significant difference between the two groups(P

Acute poisoning occurs in age of children and threatens children's life.In developed country,monitoring network about children's poisoning showed related risk factors,which helped preventing and managing poisoning quickly.The fatality rate of children's poisoning is high in China.There is no monitoring network in our country.We summarized the influencing factors and treatment of acute poisoning in children.

OBJECTIVE To evaluate the present condition of bacteriological infection caused by drainage tube after modified radical mastectomy(MRM) and the prevention measure.METHODS Atotal of152 patients with drainage tube after MRM during 2005-2007 were analyzed,bacteria culture of drainage fluid from breast wound or axillary wound were taken in 24 hours after operation.The bacteria or fungi were identified with ATB bacterial analysis apparatus.RESULTS Seventy specimens from 52 patients were positive(positive rate 34.2%).Of 70 strains,40 were Gram-positive cocci,24 were Gram-negative bacilli and the other 6 were fungi.The reasons of infection included subsided immunity defense system,drainage tube application,incorrect aseptic processing or disinfection procedure,and obstruction of drainage tube.CONCLUSIONS The important prevention measures of bacteria infection through drainage tube after MRM include maintenance of aseptic environment in operating room,strict aseptic processing,fluent drainage,and proper indwelling time of drainage tube.

The course of audiology is both important and difficult to the undergraduate education of otolaryngology.Through a series of reforms in teaching contents and methods of audiology,the students'effect of study were greatlyimproved,and thus these reforms were generally appreciated by both teachers and students. In conclusion, the act of theteaching reform not only advanced the students' learning enthusiasm and gumption, but also helps the development andexercise in their clinical thinking ability.

Glioma is the most common primary malignant tumor in the brain.Although through standardized treatment,including the largest range of surgical resection and subsequent radiotherapy and chemotherapy,the morbidity and mortality is still high,so we need a new treatment.The oncolytic virus antitumor concept was mentioned in the early 20th century,which is a kind of antitumor virus,people found that cancer patients infected with certain viruses,the tumor was gradually disappeared.With the development of Molecular Biology,Immunology,Virology and Genetic Engineering,oncolytic virus becomes a new method of tumors treatment,which attracts more and more researchers' attention,so we made an overview in the antitumor principle of oncolytic virus and its clinical application in the treatment of glioma.

The incidence of invasive fungal infection in critically ill patients is increasing year by year. Its clinical manifestation lacks specificity which is difficult for early diagnosis. It′s hard to identify inva-sive fungal infection with fungal colonization in clinical practice. We need to find out the way to distinguish them.
