OBJECTIVE:To optimize ultrasonic-assisted extraction technology of total flavonoids from Vaccinium uliginosum. METHODS:Based on single factor test,the ultrasonic-assisted extraction technology of total flavonoids from V. uliginosum was op-timized by orthogonal test,using the yield of total flavonoids as index,with ethanol volume fraction,solid-liquid ratio and ultrason-ic power as factors. The optimized technology was validated and compared with traditional ethanol reflux method(reflux extracting for 2 times,2 h each time). RESULTS:The optimal extraction technology was as follows as the solid-liquid ration of 1:25,70%ethanol,ultrasonic power of 250 W(40 min for ultrasonic time). In validation test,the yield of total flavonoids from V. uliginosum was 3.98%(RSD=0.41%,n=3),and the yield of total flavonoids was 2.25% by ethanol reflux method. CONCLUSIONS:The ultrasonic-assisted extraction is obviously superior to ethanol reflux method on extraction time and effects,and it is suitable for in-dustrialized production.

ObjectiveTo observe the efficacy of maintenance hormonal treatment after response to chemotherapy in advanced breast cancer. Methods8 patients with advanced breast cancer were treated with chemotherapy,maintenance hormonal therapy were given after response to chemotherapy.The efficacy was evaluated every 2 cycles of chemotherapy and 2 months of endocrine therapy according to RECIST standard.Results8 patients received chemotherapy for 2-8 cycles (median 4 cycles). All patients got PR, the duration of chemotherapy was 1-6 months (median 2 months), the time to failure of chemotherapy was 4 months. Until the last follow-up day (31th December 2010), the time to progression was 6-86 months (median 13.5 months).Survival was 6-86 months(median 21.5 months).Seven patients quit the chemotherapy due to severe side effects of hematologic toxicity,fatigue or nausea vomiting.One patient died because of allergy to paclitaxol.Conclusion Maintenance hormonal treatment after patients with metastatic breast cancer response to chemotherapy may prolong the duration of effective therapy and improve the QOL.

Objective To observe the effects of a natural static magnetic field (NSMF) on the proliferation of human hepatocarcinoma cells. Methods Three human hepatocarcinoma cell lines ( BEL-7402,HEP G-2 and QGY-7701 ) were cultured under standard conditions and then exposed to NSMFs of 0.1 Tesla at 600 Hz,0.2 Tesla at 250 Hz,0.2 Tesla at 400 Hz or 0.2 Tesla at 500 Hz for 30 minutes daily for 3 or 6 days.Flow cytometry and the XTT cell proliferation assay were used to check apoptosis and the proliferation of cells all groups. Results Only exposure to 0.2 Tesla magnetism at 400 Hz induced apoptosis of the BEL-7402 cell line.None of the NSMFs induced apoptosis in the other 2 hepatocarcinoma cell lines. Conclusions Different reactions of the three hepatocarcinoma cell lines to the same NSMF implies that each cell line has its own features,and that individualized NSMF treatment protocols should be adopted for better clinical outcomes.

Objective To probe the cause of the infant nutritional iron deficiency anemia,so to decrease effectively the percentage of afflicting such ill.Methods Investigate,count and analyze 418infants'data on brease-feeding and subsidiary food-feeding.These infants aging 6 months,1 year and 1.5years,visited Zhengzhou Maternal and Child Health Hospital periodically.Results The affliction percentage of infants aging 6 months,1 year and 1.5 years,is 26.11%,19.17%and 11.02%respectively,a significant difference may be found between the value(X2=10.28,P＜0.05);The affliction percentage of the breast-fed and non-breast-fed infants aging 6 months iS 22.46%and 38.10%,a significant difierence may also be found between the value(x2=4.08,P＜0.05);The affliction percentage of the mother's milk is rich and unitary infants aging 6 months is 16.50%and 40.00%.a significant difierence may also be found between the value(x2=8.28,P＜0.05).Conclusions Mother's milk is the ideal food for infants;subsidiary food shall be added timely and properly when the infant ages 6 months;infant systematic caring plays a very important role in the infant development,all intensive project on this issue must be carried out seriously.

In a previous study, we cloned popW from Ralstonia solanacearum strain ZJ3721, coding PopW, a new harpin protein. The procaryotically expressed PopW can induce resistance to Tobacco mosaic virus (TMV), enhance growth and improve quality of tobacco, when sprayed onto tobacco leaves. Here, we constructed an expression vector pB- popW by cloning popW into the bionary vector pBI121 and transformed it into Agrobacterium tumefaciens strain EHA105 via freeze-thaw method. Tobacco (Nicotiana tobacum cv. Xanthi nc.) transformation was conducted by infection of tobacco leaf discs with recombinant A. tumefaciens. After screening on MS medium containing kanamycin, PCR and RT-PCR analysis, 21 T3 lines were identified as positive transgenic. Genomic intergration and expression of the transferred gene were determined by PCR and RT-PCR. And GUS staining analysis indicated that the protein expressed in transgenic tobacco was bioactive and exhibited different expression levels among lines. Disease bioassays showed that the transgenic tobacco had enhanced resistance to TMV with biocontrol efficiency up to 54.25%. Transgenic tobacco also exhibited enhanced plant growth, the root length of 15 d old seedlings was 1.7 times longer than that of wild type tobacco. 60 d after transplanting to pots, the height, fresh weight and dry weight of transgenic tobacco were 1.4, 1.7, 1.8 times larger than that of wild type tobacco, respectively.

Hepatitis B virus infection is the major cause of chronic hepatitis B(CHB),liver cirrhosis(LC),and hepatocellular carcinoma(HCC).Over 47 000 people die of LC and HCC caused by HBV infection in the world each year.This article introduces the related variations of hepatitis B virus and the correlation with clinical treatment and prognosis.

AIM: To quantify magnesium isoglycyrrhizinate(MGL) and glycyrrhetic acid in the plasma of dog by develop a simple, rapid, sensitive high-performance liquid chromatography (HPLC-UV) method. METHODS: HPLC-UV methods with wavelength 252 nm were used for the quantitation of MGL and GA in plasma. The concentration of MGL and GA were assayed on a Kromasil ODS-1 C18 column with the column temperature 25 ℃. The mobile phase was a gradient system with 0.1 % diethylamine in water (pH 4.60 ) and acetonitrile at a flow rate of 1.0 ml?min~ -1 . RESULTS: There was a good linear response range of 0.2 -2.5 mg?L~ -1 and 2.5 -100 mg?L~ -1 , while the limit of quantification was 0.2 mg?ml~ -1 . The relative recovery rate of MGL was 94.3 %-101.9 %,GA 96.4 %-101.9 % (n=5);the absolute recovery rate was MGL 78.7 %-87.0 %, GA 77.5 %-87.7 % (n=5). The intra-day and inter-day variations were all less than 15% (n=5). The plasma samples preserved in refrigerator is stable at -20 ℃ for 14 days, freeze thawing 3 times and at room temperature for 10 h without degradation. CONCLUSION: This method is shown to be specific, sensitive, reliable and suitable for the quantitative determination of magnesium isoglycyrrhizinate following oral administration in biological sample.
