Objective To observe the effects of different gastrointestinal reconstruction methods after dis -tal subtotal gastrectomy on nutritional condition and blood glucose in patients with type 2 diabetes ( T2DM) and gastric cancer.Methods 88 patients with T2DM and gastric cancer undergoing radial distal gastrectomy were studied and among them 43 patients had Billroth I gastrointestinal reconstruction , 22 patients had Billroth II gas-trointestinal reconstruction and 23 patients had Roux-en-Y gastrointestinal reconstruction .Body mass index ( BMI) , serum albumin and prealbumin of the 3 groups were measured preoperatively and 1 year after surgery . The patients were followed up .Results There was no significant difference among the 3 groups in preoperative values(P>0.05).One year after surgery, BMI, serum albumin and peralbumin in the 3 groups had different de-grees of reduction , but showed no statistical difference ( P>0.05 ) .The effective rate of diabetes control was 18.60%in Billroth I group , 72.73%in Billroth II group , and 73.91% in Roux-en-Y group and the difference had statistical significance(χ2 =17.390 3,P<0.05).The effective rates of diabetes control in Billroth II group and Roux-en-Y group were higher than that in Billroth I group (χ2 =18.340 9,P<0.05;χ2 =19.480 4,P<0.05), and there was no evident difference between Billroth II group and Roux-en-Y group(χ2 =0.008 1,P=0.928 4).Conclusion Billroth II and Roux-en-Y gastrointestinal reconstruction can improve glycemic metabo-lism of patients with T2DM and gastric cancer without significantly reducing the nutrition status .

Tissue engineering has always been a hot spot in the life science area over the past few years. However, there are some problems, such as the multiplication of seeding cells, the preparation of tissue engineering scaffolds, and the controlled release of drugs from scaffolds and so on. Recently microspheres have been widely used to solve these problems. For example, microspheres are used as microcarriers to culture seeding cells. In addition, microsphers can be either used to prepare engineering scaffolds or directly used as scaffolds. Microspheres can be used to load drugs and control the drug release as well. In this paper the application of microspheres in tissue engineering is reviewed and the up-to-date methods are introduced, including ways of improving performances of microcarriers, preparing scaffolds with microspheres and adding drug-loaded microspheres into scaffolds.

Ten glucosyloxybenzyl 2-isobutylmalates and one benzyl alcohol glycoside were isolated from the dry tuber of Pleione bulbocodioides, which is a specie of Orchidaceae family and its dry tuber is one of the main sources of traditional Chinese medicine "shanci-gu", by a combination of various column chromatographic methods, including ODS, macroporous adsorbent resin, Sepheadex LH-20, and preparative HPLC. Their structures were identified on the basis of chemical evidences and spectroscopic analysis asloroglossin (1), grammatophylloside A (2), cronupapine (3), (-)-(2R, 3S)-1-(4-β-D-glucopyranosyloxybenzyl)-4-methyl-2-isobutyltartrate (4), vandateroside II (5), grammatophylloside B (6), bis [4-(β-D-glucopyranosyloxy) -benzyl] (S) -2-isopropylmalate (7), gymnoside I (8), militarine (9), dactylorhin A (10), gastrodin (11). Compounds 1-7 were isolated from this genus for the firt time.

This study was to investigate the chemical constituents from pseudobulbs of Pleione yunnanensis, one of the source of traditional Chinese medicine "Shancigu". The chemical constituents were isolated by various chromatography methods, including silica gel, ODS, Sephadex LH-20, and semi-preparative HPLC. Fourteen compounds were isolated and identified from the EtOAc fraction of 90% ethanol extract, including five dihydrophenanthrenes, four bibenzyls, two triterpenoids, and three phenylacrylic acids. Their structures were identified on the basis of the spectral data as 4, 7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene (1), 4, 7-dihydroxy-1-(p-hydroxybenzyl)-2-methoxy-9,10-dihydrophenanthrene (2), (2,3-trans)-2-(4-hydroxy-3-methoxyphenyl) -3-hydroxymethyl-10-methoxy-2,3,4,5-tetrahydro-phenanthro[2,1-b]furan-7-ol (3), pleionesin B (4), blestriarene A (5), batatasin III (6), 3, 3'-dihydroxy-2-(p-hydroxybenzyl) -5-methoxybibenzyl (7), 3', 5-dihydroxy-2-(p-hydroxybenzyl) -3-methoxybibenzyl (8), 3,3'-dihydroxy-2,6-bis(4-hydroxybenzyl) -5-methoxybibenzyl (9), triphyllol (10), pholidotin (11), (E) -p-hydroxycinnamic acid (12), (E)-ferulic acid (13), and (E)-ferulic acid hexacosyl ester (14). Compounds 5,10-14 were separated from this plant for the first time.

Cervical necrotizing fasciitis (CNF) is an aggressive infection associated with high mortality. Various complications have been described in previous literature. However, internal jugular vein thrombosis is rare in such lesions. We presented a case of internal jugular vein thrombosis caused by CNF and analyzed related literature.

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.

Objective To detect the preliminary results of combined periacetabular and intertrochanteric osteotomies for complex hip dysplasia.Methods From January 2006 to August 2011,23 patients (25 hips) with complex hip dysplasia were treated with combined periacetabular and intertrochanteric osteotomies (ITO).Valgus ITO was performed on 2 hips and varus ITO on others.The averagc age of patients at the time of index procedure was 20.5± 3.9 years (range:15 to 26).The hip pain period before surgery varied from 5 to 24 months (mean 11±4.7 months).The Shenton's line was broken in every hip and the mean preoperative lateral central edge angle (LCEA) was 5.6°±4.6°.The average preoperative fenoral neck-shaft (CCD) angles were 158°±3.2° and 110° in 23 valgus hips and both of two varus hips respectively.The preoperative Harris hip score was 76.7±3.7.According to T(o)nnis osteoarthritis grades,there were 7 hips at grade 0,12 hips at grade Ⅰ and 6 hips at grade Ⅱ.Results The mean followup period was 40±18 months (range:12 to 78).The CCD angle (130°±2.1°),LCEA (28.6°±2.9°) and Harris hip score (90.8±3.3)were all improved postoperatively,whereas no progression was found in preoperative T(o)nnis grades.The postoperative Harris hip scores were excellent in 17 hips and good in 8 hips.The T(o)nnis osteoarthritis grades were grade 0 in 6 hips,grade Ⅰ in 11 hips and grade Ⅱ in 8 hips.There wcre six cases with lateral femoral cutaneous nerve injury,three cases with limp and two cases with broken Shenton's line.Neither femoral head necrosis nor bone nonunion was found in this study.Conclusion Satisfactory preliminary results could be obtained through combined periacetabular and intertrochanteric osteotomies among patients with complex hip dysplasia.The risk of femoral head necrosis and bone nonunion was low.
