Objective To establish a UV spectrophotometry method and an HPLC method respectively for the determination of the total content of coumarin and contents of four main constituents of coumarin in Fraxini Cortex extract.Methods UV spectrophotometry was used for the determination of the content of total coumarin in Fraxini Cortex extract. The reference substance was Aesculin, and the maximum ultraviolet absorption wavelength was 334 nm. The HPLC method was used to determine the contents of Aesculin, Fraxin, Aesculetin and Fraxetin in Fraxini Cortex extract, using gradient elution with acetonitrile-phosphate solution (0.01%) as mobile phase on Agilent ZORBAX SB-C18 chromatographic column (4.6 mm × 250 mm, 5μm) at room temperature.Results For the UV method, the linear range of the mass concentration of Aesculin was 5.76-23.04μg/mL (r=0.999 9), and the average recovery was 100.6% (RSD=1.8%). For the HPLC method, the linear ranges of the mass of Aesculin, Fraxin, Aesculetin and Fraxetin were 0.055 0-3.850 0μg (r=0.9997), 0.053 9-3.773 0μg (r=0.999 8), 0.060 0-0.660 0μg (r=0.999 9), and 0.056 2-0.618 2μg (r=0.999 9), respectively, and the average recoveries were 96.97% (RSD=1.26%), 100.80% (RSD=2.22%), 99.04% (RSD=2.47%), and 98.77% (RSD=1.94%), respectively.Conclusion Both of the two methods are simple, accurate and reliable, and can be used for the quality control of total coumarin and the main constituents of coumarin in Fraxini Cortex extract.

ObjectiveTo investigate the effect of scalp point penetration combined with rehabilitation training on content of endothelin (ET) and calcitonin gene-related peptide (CGRP) in plasma of patients with acute cerebral hemorrage (ACH).Methods90 ACH patients were randomly divided into the scalp point penetration combined with rehabilitation group (group A), the rehabilitation group (group B) and control group (group C) with 30 cases in each group. The radioimmunoassay was adopted to determinate the content of ET and CGRP in plasma of patients.ResultsAfter treatment, contents of ET and CGRP of all patients were decreased significantly (P<0.01), but group A and group B had a significant difference compared with the group C (P<0.01), and there was also a significant difference between the group A and group B.ConclusionThe scalp point penetration combined with rehabilitation training can regulate the content of ET and CGRP in plasma and make them under a dynamic balance.

Objective To study the determination method of total flavonoids in Gansu Astragali Radix and Hedysarum Polybotrys. Methods Calycosin glycosides etc. was selected as reference substances, comparison on the difference of absorption curves was done by ultraviolet spectroscopy and colorimetric method (NaNO2-Al(NO3)3-NaOH, AlCl3, Mg(Ac)2, NaOH, phosphomolybdic acid, HCl-Mg power). Results With colorimetric method, the maximum absorption wavelength of referrence and the test was inconsistent. The absorption peak shape was also different. With UV method, Calycosin glycosides in band Ⅱ (260 nm) showed a shoulder absorption. Astragali Radix and Hedysarum Polybotrys also showed characteristic shoulder absorptions in band Ⅱ with absorption wavelength at 263 nm and 265 nm. So the sample absorption wavelength is basically the same as that of the control sample. Conclusion Colorimetries usually used for determination of total flavonoids are not suitable for the comparison determination of Gansu Astragali Radix and Hedysarum Polybotrys. It is suitable for determining the contents of total flavonoids in samples by UV spectrophotometry at the band Ⅱ, which is the characteristic absorption band of isoflavone compound.

Objective To study the effects of different extraction processes on extraction rate of cortex fraxini total coumarin and active constitute percentage of major coumarin;To establish a proper extraction process.Methods Orthogonal design method was applied to set comprehensive index cortex fraxini total coumarin extraction rate as inspecting index. Water and alcohol were used as solvent respectively to optimize the extraction process of cortex fraxini.Results Optimal water extraction process:cortex fraxini decoction pieces mixed with nine times of water, decocted for three times, 90 mins each time. The pasty fluid generating rate of cortex fraxini was 28.87%, total coumarin percentage was 19.26%, extraction rate was 5.56%, total percentage of Aesculin, Aesculetin, Fraxin, Fraxetin was 13.47%, when water was used as solvent. Optimal alcohol extraction process:cortex fraxini decoction pieces mixed with eight times of 75% ethyl alcohol, refluxed twice, two hours each time. The pasty fluid generating rate of cortex fraxini was 30.47%, total coumarin percentage was 21.72%, extraction rate was 6.62%, total percentage of Aesculin, Aesculetin, Fraxin, Fraxetin was 15.29%, when alcohol was used as solvent. It was found that using alcohol as solvent had a 5.54% higher pasty fluid generating rate, a 12.77% higher total coumarion percentage, a 19.06% higher total coumarin extraction rate, and a 13.51% higher percentage of total four coumarin constitutes than using water, with statistical significance. Conclusion Extraction process by using alcohol as solvent is better than using water. So the optimal and stable extraction process of cortex fraxini total coumarin is using 75% alcohol as solvent.

OBJECTIVETo evaluate the relationship of micrometastatic cancer cells in the blood and prognosis of patients with non-small cell lung cancer (NSCLC).

METHODSBlood samples were collected from peripheral vein perioperatively and from the pulmonary vein intraoperatively in NSCLC patients. Cancer cells were detected by flow cytometry, as described previously. The patients were followed up and analyzed statistically.

RESULTSCancer cells in blood samples were detected in 20 of 58 patients (34.5%). Patients under 57 years of age or with stage III/IV lesions had higher positive findings than those over 57 years or with stage I/II lesions (P = 0.000 and 0.006, respectively). On the basis of 40 month follow-up data, the 2- and 3-year survival rates of patients with positive and negative results were 30.0% vs 20.0%, and 52.6% vs 50.0%, respectively. There was significant difference between the overall survival curves which favored patients with negative findings (P = 0.0291 and 0.0092, respectively).

CONCLUSIONThis study indicates that cancer cells can be detected in the blood perioperatively from NSCLC patients which means poor prognosis.

OBJECTIVETo evaluate the bone-implant interfaces of two kinds of implants with different surfaces in different time in vivo.

METHODSCDIC and ITI-TPS solid-screw cylinder pure titanium implants were selected and implanted in the regions of posterior molars of rhesus monkeys. 1 month, 2 months, 3 months and 1 year after surgery, the bone-implant interfaces were evaluated respectively through oral examination, X-ray inspection, light microscope and scanning electron microscope (SEM) observation.

RESULTSNone of the implants was loose. Soft tissue around implants appeared no inflammation. There were no apparent transparent shadow around the implants interfaces in X-ray photos except little angle-shaped absorption was showed in neck region of CDIC implants of one-month. New bone was observed around implants of one-month through light microscope and SEM. More bone growing around ITI implants were seen than that around CDIC implants except the interfaces of one-year.

CONCLUSIONThe osseointegration of ITI implants are better than that of CDIC implants during three months after implanting without loading. The bone formation at the interfaces of ITI and CDIC implants has no significant difference after one year without loading.
