Chinese Traditional and Herbal Drugs 2019;50(18):4313-4319
Objective: To optimize the water extraction process of Siwu Decoction by BP neural network combined with orthogonal experiment. Methods: The water amount, the extraction time, and the extraction times were taken as factors. Entropy weight method was used to calculate the comprehensive scores of the multi-indicators of eight active components of 5-hydroxymethylfurfural, chlorogenic acid, caffeic acid, paeoniflorin, ferulic acid, verbascoside, senkyunolide A, and ligustilide in R language environment. Using comprehensive score as an evaluation indicator, the BP neural network model was established by orthogonal experiment design, and the optimal water extraction process of Siwu Decoction was predicted through network training. Results: The optimized extraction process of Siwu Decoction was carried out by adding 8 times of water and extracting 3 times for 1 h. The relative error between the network predicted value and the actual measured value of the test sample was less than 1%. Conclusion: The established mathematical model can analyze and predict the water extraction process of Siwu Decoction. The obtained process is stable and feasible, and can effectively extract the active ingredients in Siwu Decoction.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

Objective To investigate the nutrition status of the focus groups of iodine deficiency in the 5 coastal counties(districts)in Guangxi in 2008 to propose corresponding prevention and control measures.Methods In the 5 coastal counties(districts)in Guangxi,including Haicheng,Tieshangang,Yinhai districts and Hepu county in Beihai city,Qinnan district in Qinzhou city,the rates of iodized salt coverage,qualified iodized salt and consumption of qualified iodized salt had always been below the average level of Guangxi.In the study,6 towns were randomly picked in Hepu district,and 3 towns were randomly picked in each of the other 4 coastal counties(districts).Two administrative viRages were randomly picked in each town.Forty children ages 8 to 10 and 10 women of child-beating age from 18 to 42 which included 5 pregnant and lactating women,were picked from each administrative village.Arsenic-cerium catalyzed spectrophotometry(WS/T 107-2006)Was used to determine the urinary iodine.Results In total,1437 urine samples of the children Were picked.The median of the children's urinary iodine Was 191.0μg/L,with 1.4%(20/1437)of the children's urinary iodine<20 μg/L,and 5.4%(77/1437)<50 μg/L, and 20.3%(292/1437) < 100 μg/L. The medians of the children's urinary iodine were 134.5 - 220.0 μg/L.In Haicheng and Hepu, the medians of the children's urinary iodine were higher than 200 μg/L(220.0,209.5 μg/L, respectively). The medians of the children's urinary iodine in the other 3 counties(districts) were within the suitable range between 100 and 200 μg/L(134.5,162.4,199.3 μg/L, respectively). The medians of the 8- and 9-year-old ehildren's urinary iodine (192.3,206.7 μg/L, respectively) were higher than that of the 10-year-old children's(157.2 μg/L, χ2 = 19.644,41.997, all P < 0.017). Totally, 365 urine samples of the women were picked.The medians of the women's urinary iodine in the 5 counties were 88.2 - 195.6 μg/L, with 195.6 μg/L in Haicheng and 156.5 μg/L in Hepu, and 88.2 μg/L in Tieshangang, which was the lowest and below 100 μg/L. The median of the childbearing-age women's urinary iodine was the highest(152.6 μg/L). The median of the lactating women's urinary iodine was the second (131.9 μg/L). The median of the pregnant women's urinary iodine was the lowest (89.4 μg/L) and below 100 μg/L. Only 6.7%(2/30) of the pregnant women's urinary iodine were within the suitable range between 150 and 250 μg,/L. Conclusions In the 5 coastal counties(districts) in Guangxi, 8 to 10-year-old children had good nutrition levels while childbearing-age and lactating women were within the suitable range. As a whole, the pregnant women had insufficient iodine nutrition. We propose that the iodine nutritional status of pregnant women is monitored routinely, with further prevention, control measures, health publicity and education necessary to improve iodized salt coverage.
