Objective: To develop an HPLC-DAD method for the simultaneous determination of five active flavonoids (quercetin, kaempferol, apigenin, 3-methoxyl-quercetin, nobiletin) in Centipeda minima (L.) A.Br.et Aschers.Methods: The chromatographic separation was performed on a Diamonsil C18 column (200 mm×4.6 mm,5 μm) with the mobile phase of 0.1% phosphoric acid-acetonitrile with gradient elution at the flow rate of 0.8 ml·min-1.The detection wavelength was set at 360nm,and the column temperature was maintained at 30 ℃.Results: Quercetin, kaempferol, 3-methoxyl-quercetin, apigenin and nobiletin was linear within the range of 0.002 3-0.093 0 μg·μl-1(r=0.999 5) , 0.002 2-0.087 0 μg·μl-1(r=0.999 6),0.002 0-0.079 0 μg·μl-1(r=0.999 8), 0.000 9-0.037 0 μg·μl-1(r=0.999 8) and 0.000 8-0.031 0 μg·μl-1 (r=0.999 9), respectively.The average recovery was 97.66%(RSD=1.17%), 98.33%(RSD=1.16%), 98.63%(RSD=1.10%), 98.40%(RSD=1.52%) and 98.10%(RSD=1.36%)(n=6) , respectively.Conclusion: The method is convenient, accurate and reproducible, which can be used for the quality control of Centipeda minima (L.) A.Br.et Aschers.

AIM　To build a model of two series of PPARγ agonists thiazolidinedione and aryketo-acid derivatives using 3D-QSAR method, and to reveal the structural features affecting the binding activity to PPARγ, which relates to antihyperglycemic and antihyperlipidemic activity and has a potential application to the treatment of type II diabetes. METHODS and RESULTS　48 agonists with selective activity for PPARγ were analyzed using CoMFA. Based upon the active conformation of rosiglitazone (BRL) extracted from its complex with PPARγ all agonists were aligned. The model from CoMFA showed a high ability to explain and predict the activity of PPARγ agonists with cross-validation correlation coefficient R2=0.656, that of non-cross-validataion R2=0.982, F10，37=201.1, and SE=0.115. CONCLUSION　The CoMFA contour map indicates that the steric fields mainly contribute to the binding effect, and especially a bulky group in the arylketo-acid series favors in the increase of affinity for PPARγ, as compared to the thiazolidinedione.

The apprentice system is the principal succession method of ancient Chinese medicine. Masters pass down knowledge via verbal instructions as well as personal deeds, and apprentices are unconsciously influenced deeply within by what they see and hear from masters. That is where the strong point of the system. However, at the same time, apprentices are confined by their master’s instructions and learn only a part of the knowledge. It is the profound meaning rather than the form, that truly represents the modern value of the system. Traditional Chinese medicine stresses the cultivation of medical ethics, purification of learning motivation, study of classic works, solid foundation of basic skills and clinical practice. It also advocates that apprentices should be led and taught in accordance to his aptitude.

·AIM: To evaluate the efficacy and safety of intravitreal triamcinolone acetonide(TA) as treatment for macular edema associated with retinal vein occlusion(RVO).·METHODS: The study group consisting 30 patients (30 eyes) with RVO combined with macular edema received intravitreal 4mg TA. Changes in best-corrected visual acuity (BCVA), intraocular pressure(IOP), examination with slit-lamp microscope, fluorescein angiography and optical coherence tomography(OCT) were observed during the follow-up. Statistical analysis was conducted with SPSS 12.0 software.·RESULTS: The visual acuity(VA) of all patients was significantly improved and the central macular thickness (CMT) was significantly relieved. There was no correlation between course, age, CMT before injection and the type of RVO. There was positive correlation between visual acuity before injection and after injection.·CONCLUSION: Intravitreal injection of TA is an easy-operated and safe therapy. After injection, macular edema can be rapidly relieved. VA at baseline is the predictor for the prognosis of VA. Some patients experience recurrence of macular edema between 3 to 6 months after injection.

Objective To study the impact of pregnancy on differentiated thyroid cancer. Methods Retrospective comparative analysis were made between pregnancy-related thyroid cancer patients ( including nine months before delivery and one year after delivery) and the age-matched non-pregnancy-related thyroid cancer patients treated in the Department of head and neck, Fudan University Shanghai Cancer Center. Results There were 125 cases of pregnancy-related thyroid cancer patients from 1998 to 2008, including 28 cases (22.4%) of neck recurrence and metastasis after the surgery of thyroid cancer, meanwhile there were 691 cases of the agematched non-pregnancy thyroid cancer patients, including 90 cases ( 13% ) of neck recurrence and metastasis after the surgery of thyroid cancer. The rate of neck recurrence and metastasis after the surgery of thyroid cancer in the pregnancy-related group was higher than that in the non-pregnancy related group ( P ＜ 0.05). The maximum diameter of tumor in the pregnancy-related group and the non-pregnancy group is 2. 1 cm and 2.6cm respectively.There were 19 cases of multi-focal cancer ( 19.6% ) in the pregnancy-related group and 58 cases (9. 6% ) in the non-pregnant group, P ＜0.05. There were 23 patients (23.7%) of extrathyroid invasion in the pregnancy-related group and 65 patients ( 10.8% ) in the non-pregnant group, P ＜0.05. There were 67 cases (53.6%) and 35 cases (28%) of the central and lateral cervical lymph node metastasis in the pregnancy-related group respectively and 296 cases (42.8%) and 117 cases (16. 9% )in the non-pregnant group, P ＜0.05. There were 19 cases (15.2%) of extralymph invasion in the pregnancy-related group and 32 cases (4.6%) in the non-pregnant group, P ＜ 0.05. Conclusions The incidence of Extrathyroid invasion, multi-focal cancer, cervieal lymph node metastasis and extralymph invasion of the differentiated thyroid cancer is higher in pregnancy-related patients.Pregnancy may deteriorate the prognosis of thyroid cancer. For patients after the surgery of thyroid cancer, pregnancy may increase the risk of neck recurrence and metastasis. However, pregnancy does not affect the stage of thyroid cancer and the prognosis is still good.
