In total, 607 bedridden patients aged 60 years and over at Tianlin community hospital and four other hospitals or at home-care in Shanghai were investigated with questionnaire, physical examinations and related laboratory tests. Contents of investigation include general situation, medical conditions, 24-hour recall of diet, intake of nutritional supplement preparation, and so on. As compare to the reference for nutrient intake of the elderly set in the Guide to Diet for Chinese Residents (2007), total nutritional intake was obviously insufficient and three nutrients in diet were imbalanced for most bedridden elderly patients. Intake of most nutrients (including proteins, dietary fiber, calcium, iron, zinc, selenium,copper, magnesium, phosphor, retinol equivalent, vitamin B1 , vitamin B2, vitamin C) was obviously low in bedridden elderly patients, with a larger gap from the requirements of the Dietary Guide.

OBJECTIVETo study the intestinal absorption mechanism of tilianin in rats.

METHODThe single-pass perfusion model was established in rats. The concentrations of tilianin with in situ intestinal perfusion were determined by HPLC. The impact factors, such as verapamil, reserpine, phloridzin and rifampicin, on Ka and Papp of tilianin in rat jejunum were investigated.

RESULTCompared with the control group, Ka and Papp in rat jejunum were significantly higher after being added with verapamil and reserpine (P < 0.05). Papp of tilianin in rat jejunum was significantly lower after being added with phloridzin (P < 0.05). Compared with the control group, both Ka and Papp of tilianin in rat jejunum were not significantly higher after being added with rifampicin.

CONCLUSIONTilianin is the substrate of P-gp, BCRP and SGLT1. The effluent effect of P-gp and BCRP is the main mechanism of tilianin in intestinal absorption, indicating that tilianin can realize intestinal absorption and transport by relying on SGLT1. Tilianin is not the substrate of bile salt transporter protein.

This study is designed to explore the possible effects of Hemerocallis citrina baroni flavonids (HCBF) on liver fibrosis induced by CCl4 in rats. The liver fibrosis model was induced by CCl4, and HCBF were administered by gastric perfusion at 25 and 50 mg x kg(-1) qd for 50 days, while the contents of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), superoxide dismutase (SOD), maleic dialdehyde (MDA) and transforming growth factor-β1 (TGF-β1) were measured and the contents of PINP were measured in liver tissue, and the expression of TGF-β1 were observed by immunohistochemisty and Western blot. The pathological changes of liver tissue were examined by HE. The results showed that HCBF (25, 50 mg x kg(-1)) improved the liver function significantly through reducing the level of ALT, AST, GGT and ALP (P < 0.05 or P < 0.01), and increasing the content of SOD (P < 0.01), while reducing the content of MDA (P < 0.05 or P < 0.01), the expression of TGF-β1 (P < 0.05) and the content of PINP (P < 0.05). The results suggest that HCBF (25, 50 mg x kg(-1)) may inhibit the liver injury induced by CCl4 by decreasing the oxidative stress.

Curcumin-ethyl-cellulose (EC) sustained-release composite particles were prepared by using supercritical CO2 anti-solvent technology. With drug loading and yield of inclusion complex as evaluation indexes, on the basis of single factor tests, orthogonal experimental design was used to optimize the preparation process of curcumin-EC sustained-release composite particles. The experiments such as drug loading, yield, particle size distribution, electron microscope analysis (SEM) , infrared spectrum (IR), differential scanning calorimetry (DSC) and in vitro dissolution were used to analyze the optimal process combination. The orthogonal experimental optimization process conditions were set as follows: crystallization temperature 45 degrees C, crystallization pressure 10 MPa, curcumin concentration 8 g x L(-1), solvent flow rate 0.9 mL x min(-1), and CO2 velocity 4 L x min(-1). Under the optimal conditions, the average drug loading and yield of curcumin-EC sustained-release composite particles were 33.01% and 83.97%, and the average particle size of the particles was 20.632 μm. IR and DSC analysis showed that curcumin might complex with EC. The experiments of in vitro dissolution showed that curcumin-EC composite particles had good sustained-release effect. Curcumin-EC sustained-release composite particles can be prepared by supercritical CO2 anti-solvent technology.

OBJECTIVETo analyze the reversal effect of Buzhong Yiqi Decoction (BYD) on multidrug resistance of human adenocarcinoma of lung cell line A549/DDP, and to study its effect on the expression of survivin by using serum pharmacological methods in vitro. Methods Totally 24 SD rats were divided into the high, medium and low dose groups, and the blank control group by randomized controlled method. The high dose BYD containing serum (1. 134 g/mL, 2 mL), the middle dose BYD containing serum (0.576 g/mL, 2 mL), and the low dose BYD containing serum (0.284 g/mL, 2 mL) were prepared. The inhibitory effects of different dose and concentrations BYD on the proliferation of A549 and A549/DDP cells were detected by MTT assay, and the drug resistance reversal fold was calculated. The expression of Survivin in the two cell strains were detected respectively by immunohistochemical assay, Western blot, and immunofluorescence method.

RESULTSBYD containing serum showed obvious inhibitory effect on the growth of A549 and 549/DDP. The inhibition rates of 10% dose groups were higher than those of 5% dose groups. Besides, it gradually increased along with increased concentrations. Compared with 10% blank control group, the inhibition rate increased in 10% middle and low dose groups (P <0.05). After acted with 10% middle dose BYD containing serum, IC50, of A549 and A549/DDP were both reduced (P <0.05), reversal fold (RF) both increased. Its reversal ratio on A549/DDP cells was 2. 46, decreasing the resistance of A549/DDP to DDP. Compared with A549 in the same group, the expression of Survivin was detected to decrease by immunocytochemical assay, Western blot, and immunofluorescence method (P<0.05). Compared with 10% blank control group, the inhibition rate decreased in 10% middle dose group (P <0. 05).

CONCLUSIONS10% middle dose BYD containing serum could significantly inhibit the apoptosis of A549 and A549/DDP. Besides, it could moderately reverse the multidrug resistance of A549/DDP cells to DDP possibly through reducing the intracellular expression of Survivin and enhancing the sensitivity 549/DDP to chemotherapeutics.
