AIM: To establish the quality standard for Duhuo Jisheng Mixture (Radix Angelicae Pubescentis, Herba Taxilli, Cortex Fraxini, etc.) METHODS: Herbs in Duhuo Jisheng Mixture were identified by TLC, and osthol content was determined by TLCS. RESULTS: Rhizoma Chuanxiong; Radix Angelicae Sinensis; Radix Saposhnikoviae; Radix Gentianae Macrophyllae; Cortex Eucommiae; Herba Asari; Radix Paeoniae Alba could be determined. Osthol showed a good linear relationship at a range of 0.466 - 3.600 ?g,r= 0.999 2 . The average recovery was 95.4% . CONCLUSION:The methods are available with a reproducibility and can control the quality of this mixture.

AIM:To study the detection limits of aristolochic acid in Herba Asari preparation by HPLC. METHODS: Whether Asarum hetertropoides Fr.Schmidt ver.Mandshuricum(Maxim.) Kitag contained aristolochic acid A or not by HPLC and MS,and the difference in the reference substance and the sample solution was compared. RESULTS: Aristolochic acid A could not be found in A.hetertropoides Fr.Schmidt ver.Mandshuricum(Maxim.)Kitag by HPLC,but be found by MS. CONCLUSION:A.hetertropoides Fr.Schmidt ver.Mandshuricum (Maxim.)Kitag contained trace aristolochic acid,but it is difficult to measure aristolochic acid in Herba Asari by HPLC.The baseline noise of the sample solution can interfere with the detection limit of the trace compound compound

Objective: To study the floating and sustained release performance of Xiaojin Cinnabar Floated Sustained Release Capsules. Methods: HPMC was used to form the framwork of floated sustained release capsules containing Xiaojin Cinnabar. The content, floating time in vitro and releasing rate were studied.Results: The floating time in vitro was over 3 hours. The total released amount in 3 hours came to 60%. The conventional Xiaojin Cinnabar didn't have the floating performance. Conclusion: Xiaojin Cinnabar Floated Sustained Relegse Capsules is superior to the conventional Xiaojin cinnabar in the sustained release performance.

As a new concept, the definition of translational medicine remains obscure. The translational medicine connects the bench to bedside, and its importance would be more remarkable. The development of gastrointestinal surgery reflects the idea of translational medicine. To carry out the translational study, the gastrointestinal surgeon must learn how to find subjects from clinical problems, how to collect complete information and tissues, how to collect complete information and tissues, how to collaborate with others from different fields and how to utilize all kinds of resources. By translational studies, gastrointestinal surgeons may further improve the survival of patients with gastrointestinal tumor.

Objective To probe into the medical cost and economic losses of childhood asthma. Methods Total 200 of asthmatic children aged 2~16 yrs were diagnosed according to asthma OPD and enrolled in this study from the Affiliated Hospital of Medical College of Qingdao University during 2005—2006. All of them were taken the epidemiologic and economic survey. Results Among them, 184 were from kindergartens, primary or middle schools. There were totally 7 629 days for the asthmatic children absent from class per year because of illness. The overall direct economic loss was RMB 798 467.00 and indirect loss was RMB 210 997.80 yearly. Conclusion Asthma not only brings about great impact on children physical and mental health, but also exerts massive economic loss on the society and families. The whole society and medical workers should pay more attention to it and try to reduce its harm to a relatively low level.

Objective: To evaluate the clinical effect and adverse reactions of radioactive seed interstitial brachytherapy com-bined with etoposide (EP) regimen concurrent chemoradiotherapy treatment for locally advanced non-small cell lung cancer. Methods:All 24 cases of locally advanced non-small cell lung cancer received three-dimensional conformal intensity modulated radiation therapy by using 6 MV X-ray to obtain 95%60-66 Gy/30-33 F planning target volume. All cases received radiation therapy five times a week. EP regimen chemotherapy concurrent with radiotherapy was given to 24 patients. The therapy included VP-16, 60 mg/m2 intravenous in-fusion for 1 d to 5 d, and DDP 50 mg/m2 intravenous infusion on the 1st, 8th, and 28th therapy day. Chemotherapy with EP regimen was given for four cycles, in which two cycles were given during radiotherapy and the remaining cycles were completed after radiotherapy. The patients were reexamined three months after concurrent chemoradiotherapy was completed. Patients with residual tumor, con-firmed via positron emission tomography/computed tomography, underwent 125I radioactive seed implantation interstitial brachytherapy to complement the dose of tumor. Results: The response rate was 83.3% (20/24); the local control rates of 3, 6, 9, 12, 18, and 24 months were 87.5% (21/24), 83.3% (20/24), 75.0% (18/24), 70.8% (17/24), 58.3% (14/24), and 50.0% (12/24). The median survival was 20.2 months. The one-year survival rate was 62.5%, and the two-year survival rate was 37.5%. The following main toxicities were observed:the incidence of radiation-induced lung injury was 25%;the incidence of radiation esophagitis was 33.3%;the incidence of grades Ⅰ to Ⅱ gastrointestinal reactions was 82.3%; the incidence of reducing neutropenia was 87.5%, in which the incidence of gradesⅠtoⅡwas 75.0%, gradeⅢwas 12.5%, and gradeⅣwas 0%. Conclusion:EP regimen concurrent radiotherapy and chemo-therapy combined with radioactive seed interstitial brachytherapy for locally advanced non-small cell lung cancer is effective and has few serious adverse reactions, thus making this approach worthy of promotion.

Objective To observe the branches and distribution of the tibial nerve and analyze the compressed position of it.Methods Twenty sides of adult cadavers were anatomized and the tibial nerve branches in ankle,foot,the internal and external plantar tunnel were observed.Correlated data was measured and recorded.Results ① The tendinous part of abductor hallucis muscle that was located under the muscle and consisted the surface of the internal and external plantar tunnel was(8.62?0.79)cm in length,(3.01?0.30)cm in width,and the thickness of it was about(0.24?0.02)cm.The internal and external nerves were located in the internal and external tunnel.The length of the internal tunnel was about(4.58?0.41)cm,and the diameter was(1.11?0.10)cm.The length of the external tunnel was about(2.58?0.23)cm,the diameter was about(0.96?0.08)cm.② Internal hell nerve was in an isolated tunnel interior the hell,which was the hell tunnel.The length of the hell tunnel was about(3.03?0.21)cm,the diameter was(1.07?0.09)cm.Conclusion The tibial nerve branches can be compressed at internal,external plantar tunnel or the heel tunnel.When making neurolysis of the tibial nerve for tarsal tunnel syndrome patients,except for the flexor retinaculum,the internal and external plantar tunnel and the hell tunnel should also be decompressed especially for the patients with the symptom of compressed single branch.
