Nine compounds were isolated from the n-butanol fraction of 95% ethanol extract of the fruit of Alpinia oxyphylla Miq. with a combination of various chromatographic approaches, including MDS resin, silica gel, reverse phase C18 and preparative HPLC. On the basis of spectroscopic data analysis, they were elucidated as (1R, 4R, 10R)-1β, 4α-dihydroxy-11, 12, 13-trinor-5, 6-eudesmen-7-one (1), 1β, 4β-dihydroxy-11, 12, 13-trinor-8, 9-eudesmen-7-one (2), oxyphyllenone A (3), oxyphyllenone B (4), rhamnocitrin (5), staphylionoside D (6), benzyl-1-O-β-D-glucopyranoside (7), 2-O-β-D-glucopyranosyl-(1S)-phenylethylene glycol (8), and (S)-1-phenylethyl-β-D-glucopyranoside (9). Among them, compound 1 is a new sesquiterpene, named as oxyphyllenone C; compounds 8 and 9 are new natural products; compounds 2 and 6 were isolated from the genus Alpinia for the first time, and compound 7 was isolated from A. oxyphylla for the first time.

Objective To examine the concentrations of hepatocyte growth factor(HGF)and vascular endothelial growth factor (VEGF)in the patients with diabetic neovascular glaucoma(NVG),proliferative retinopathy without neovascularization of the iris(PDR) and idiopathic macular role(IMH),and to determine the relationship between HGF and VEGF.Design Prospective case series. Participants 14 patients(14 eyes)with NVG,22 patients(22 eyes)with non-NVI PDR,19 patients(19 eyes)with IMH.Methods The double-antibody sandwich enzyme-linked immunosorbent assay(ELISA)was used to measure the intravitreous level of HGF and VEGF.Main Outcome Measures The concentrations of HGF and VEGF in the same specimens.Results The concentrations of HGF (mean?SD)in vitreous of NVG group,PDR group and IMH group were(12908.42?2946.46)、(9770.86?3802.99)、(4160.54?2044.80)pg/ ml,respectively(Kruskal-Walls test,X~2=32.36,P=0.000).In addition,significant differences were observed between groups of the concentrations of HGF(P＜0.01,respectively).The intravitreous concentrations of VEGF(mean?SD)in three groups were(823.50?718.58)、(821.82?786.27)、(22.73?3.20)pg/ml(X~2=28.30,P=0.O00),respectively(Kruskal-Walls test,X~2=32.36,P=0.000).There was no significant correlation between the concentrations of HGF and those of VEGF in the same specimens from each group(P＞0.05, respectively).Conclusions The intravitreous concentrations of HGF in the patients with diabetic NVG are obviously higher than those with IMH and non-NVI PDR,suggesting that HGF appears to be associated with mediating the neovascularization of retina and iris in NVG.However,it is not found there is any relationship between the intravitreous levels of HGF and VEGF.

OBJECTIVETo study the influence of experimentally osteoporosis to osteogenic efficiency of bone matrix gelatin(BMG) implanted into the calvarial defects of rats.

METHODSSixty-eight female SD rats of 12 +/- 1 weeks were randomly divided into two groups with 34 rats in each group. The ovaries were excised in the ovariectomized group (VG). The control group underwent sham surgery. Ninety days after ovariectomy, 10 rats from each group were examined to ensure the formation of postmenopausal osteoporosis by measuring bone density of the femur with single photon absorptiometric measurements. A critical-sized (8 mm in diameter) calvarial defect was created on the rest of 48 rats. Bone matrix gelatin was implanted to the defect. The rats were scarified at the 21st and 56th day after surgery respectively. The new bone forming capability of BMG was evaluated with undecalcified histological observation, tetracycline fluorescence marker, quantitative bone histomorphometry, At 90th day after ovariectomy, bone density of scanning electron microscopy and X-ray spectrometry.

RESULTSOVG showed very significant difference compared with the control group (0.315 +/-.015) g/cm2 vs [(0.347 +/- 0.017) g/cm2, P < 0.01 ]. At the 21st day following the implantation operation, new bone formed within the bone defects in both groups. The amount of new bone in OVG was lower than the control group. The tetracycline-labeled region in the bone defect was sparser in the OVG. At the 56th day, the bone defects healed mostly in the control group but fibrous tissue filled parts of bone defect in the OVG. The distance between two fluorescent lines of incorporated tetracycline and the mean mineralization deposition were significantly lower in the OVG than the control at the 21st day and 56th day. Mineralization of callus in OVG was inferior. Significant difference was found between the OVG and the control group in the calcium to phosphate ratio of callus in bone defects at the two time-points.

CONCLUSIONSExperimentally induced osteoporosis depressed osteogenic efficiency of BMG, suggesting that estrogen could play an important role in bone remodeling with bone substitute participating.

Objective:Esophageal cancer has high morbidity in China, and surgery is the main treatment for this disease. Postop-erative nutrition is also important for the patients. In this article, we discuss the possibility of retrosternal route gastrostomy feeding (RGF). Methods: The data of 127 esophageal cancer patients between 2011 and 2013 were retrospectively analyzed. RGF was per-formed in all the patients, and post-operation complications were studied. Results: Bowel obstruction, catheter displacement, and wound infection did not occur. Conclusion:RGF is a safe and effective nutrition method for patients who underwent retrosternal recon-struction.
