An on-line solid phase extraction-high performance liquid chromatography ( SPE-HPLC ) system was applied in the plasma pharmacokinetic study of highly active anti-cancer compound tyrosine kinase inhibitors (TEB-415) in mouse. The on-line SPE-HPLC method associated with Ultimate3000 system which was applied to the determination of the blood drug level of TEB-415 in mouse plasma. C18 column ( Venusil MP, 150 mm × 4. 6 mm, 5μm) was used as analytical column and the mobile phase consisted of acetonitrile-5 mmol/L monopotassium phosphate buffer ( pH 3 . 5 ) at a flow rate of 1 . 0 mL/min was used as the isocratic elution. An MF Ph-1 column (10 mm×4 mm, 5 μm) was used as on-line SPE column, and water and water-acetonitrile were used as the washing solvent and elution solvent respectively. The detection wavelength was set at 262 nm. The pharmacokinetic parameters were calculated by WinNonlin 5. 2 software. The linear range of the calibration curve was between 100 and 20000 μg/L, and the limit of qualification was 20 μg/L. The extraction recovery was between 90 . 5% and 94 . 6%. The RSD of intra-day and inter-day precision was less than 3. 5%. The accuracy of short-term stability, freeze-thaw stability and long-term stability were between 91. 49% and 101. 96%. After oral medication, the mean peak time (Tmax) of TEB-415 in mice was 5. 29 h, and the mean maximum concentration ( Cmax) was 3403μg/L. The area under the curve ( AUC) of TEB-415 was 24600 μg/L·h. This drug's mean half-life was 3. 84 h, and its mean retention time (MRT) was 6. 56 h. These parameters suggested that TEB-415 had appropriate rate of absorption and elimination with preferable bioavailability.

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

The study is aimed to distinguish morphological characteristics of Dalbergiae Lignum collected from crude drug's markets and establish a identification methods and the quality standard for Dalbergiae Lignum. The macroscopic and microscopic features of Dalbergiae Lignum from crude drug's market were observed, analyzed and compared according to Hongmu specification issued by the People's Republic of China in 2000, and by the characteristics recorded in domestic monograph of Mucai Shibie (wood identification). The redwood of Dalbergiae Lignum cut into small pieces as medicinal material are dry heart wood of mahogany (trees from Dalbergia sp.), which characteristics of the small pieces as crude drug are different. There are differences in macroscopic and microscopic features about texture of wood and color, odor, taste, transverse section, radial section, tangential section. The results can provide basis for identification, application and improment of the quality standard of Dalbergiae Lignum as medicinal material.

Objective To discuss ureaplasma urealyticum (Uu) and Mycoplasma hominis (Mh)susceptibility and resistance change trend in Lanzhou recent years .Methods Detected and statistical analyzed the mycoplasma drug sensitivity level of urinary tract infection patients in urinary clinic with Mycoplasma culture sensitivity reagents from 2010 to 2014 .Results Mycoplasma to Josamycin ,Doxycycline and Clarithromycin were more sensitive .In the 12 kinds of antibacterial drugs ,we found the declining trend of Ofloxacin and Spectinomycin drug sensitivity rates ,and upward trend of Minocycline and Josamycin drug sensitivity rates .Con‐clusion Mycoplasma overall drug sensitivity rate has a gradually downward trend ,which indicating a poor drug resistance control . It′s important to strengthen the antibiotic drug surveillance and security management .

Objective:To evaluate the effects of Sander Ⅱ appliance in the orthodontic treatment of adolescent ClassⅡmalocclusion. Methods:15 cases (6 male and 9 female)of adolescent ClassⅡ malocclusion with mandibular retrution were treated with Sander Ⅱappliance.Pre-treatment and post-treatment Lateral cephalogram measurements were traced and analyzed in terms of 28 indicators. SPSS 19.0 software package was used for paired t test.Results:After treatment,15 patients achieved remarkable improvement in the maxillofacial profile and normal overjet of teeth.The cephalometric analysis showed that ANB,OJ,H°and U1-E decreased(P <0. 05),SNB,B-OLP,Pg-OLP(mm),Ii-OLP,Ms-OLP(mm),Mi-OLP(mm),N-Me,ANS-Me,S-Go,Go-Gn,N'-Pg'/FH,Cm-Sn-Ls and Pg-Pg'increased(P <0.05).There was no significant change in SN-MP,SN-OL and Y-axis before and after treatment. Conclusion:Sander Ⅱ appliance is effective in the treatment of adolescent early Class Ⅱmalocclusion.

Objective　To study the pattern of activities of microglia, the patholgical changes of chronically hypoperfused brain of rats and the interrelationship between them. Methods　Model of chronically hypoperfused brain was established in rat by the ligation of both common carotid arteries, and the histopathological changes of brain were observed with light microscope. The activity of microglia of the brain were also observed with immunohistochemistry method and the number of microglia was measured with image analyzer. Results　Extensive activation of microglia was observed after chronic cerebral hypoperfusion and the activation was increased with the elapse of time of hypoperfusion. There were obvious pathological change in the brain after the chronic cerebral hypoperfusion, such as myelinic degeneration and formation of glial nodule in white matter. After treated with cyclosporin A, the number of microglia was obviously reduced, but the pathological change was evidently decreased. Conclusion　The activation of microglia resulted from chronic cerebral hypoperfusion is relates to the pathological changes of the brain. However, cyclosporin A can decrease the pathological change and inhibit the activation of microglia.
