Objective To study CD64 expression in neutrophilic granulocyte and its clinical effect in neonatal infection disease. Methods CD64 was detected among 59 neonatal patients(septicemia group 34 patients, local infection group 25 patients)hospitalized in our neonatal department diagnosed as neonatal infection disease in 48 h after hospitalized,2 weeks after therapy, then the results were compared with 27 patients as non - infection disease during the same period. Results CD64 in septicemia group was (6156. 21?3643. 32) molecula per cell,in local infection group was (2176.19 ? 946. 32)molecula per cell, in non- infection group was (2176. 19 ? 946. 32) molecula per cell.There were significant differences among three groups (all P0.05). Conclusions CD64 expression increases in bacterium infection disease. It is more obvious in widespread infection desease.and it can be the mark in early diagnosis of neonatal infection disease.

AIMTo investigate factors affecting the properties of antisense oligodeoxy nucleotides (ASON)-liposomes complex and their cellular uptake.
METHODSThree types of blank liposomes were prepared by reverse-phase evaporation vesicles, and the complex were obtained through physical absorption. The light microscope was used to observe morphology characteristics of the complex. Drug loading capacity was analyzed by agarose gel electrophoresis. The transfected cell percentage and means fluorescence intensity were determined by flow cytometric analysis using M3 myeloma cell as a model.
RESULTSThe neutral liposome showed no aggregation while the cationic liposomes appeared some different extent aggregation in different medium when associated antisense oligodeoxynucleotides. The drug loading capacity depended on the ratio of +/- and the cationic charge density on the lipid membrane. The two kinds of cationic liposomes appeared different principles of loading ASON. As far as cellular uptake, The neutral liposomes showed no improvement of cellular uptake of ASON. However, the cationic liposomes were shown to enhance the cellular uptake of ASON if the appropriate +/- charge ratio was used. The optimal cellular uptake was achieved when +/- charge ratio was at 0.5:1 and 1:1 for SA-I liposome and SA-II liposomes, respectively.
CONCLUSIONThe cationic liposomes improved the loading capacity and cell uptake of antisense oligodeoxynucleotides, which was determined by +/- charge ratio and charge density.

OBJECTIVETo introduce an arthroscopic technique in managing recurrent dislocation of the patella and its clinical results.
METHODSSixteen patients with recurrent patellar dislocation were reviewed, including 3 males and 13 females. The average age was 17.6 years old (ranged from 14 to 32 years). The patients suffering from patellar sub-luxation averaged 18.5 months (ranged from 6 to 23 months)before operation. These patients were treated with lateral patellar retinacular release outside the synovial bursa of knee joint and medial patellofemoral ligament reconstruction using the semitendinosus tendon free autograft. The Lyshohm scores before and after operation were used to evaluate outcomes at the final follow-up.
RESULTSAll the patients were followed up, and the duration ranged from 6 to 48 months, with an average of 12 months. There was no recurrence. The Q angle decreased from (16.4 ± 3.7)° to (10.1 ± 1.4)°; insall index decreased from 1.37 ± 0.25 to 1.28 ± 0.23; congruence angle decreased from (21.3 ± 2.6)° to (5.86 ± 2.23)°; Lysholm score improved from 76.1 ± 5.2 to 89.8 ± 4.1 at 6 months after operation.
CONCLUSIONCompared with conventional procedure, arthroscopic surgery for recurrent dislocation of the patella achieves excellent outcomes with minimum invasion.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

The fundamental mechanism of gastrointestinal diseases is the imbalance between the attack factor and the protective factor of stomach mucous membrane. It can not outbreak if the protective factor is stronger than the attack factor; otherwise, it will. Attack and protective function inside the stomach are mediated by various factors. These related factors interaction constitutes a complicated network system. This kind of outbreak theories of imbalance in Western medicine is same as that, "The sense of right saves inside, the evil can't do" and "Evil is competing with right, all diseases occur", in Chinese medicine. So, it is the key which points to futher study the interaction between gastrointestinal attack factors and protective factors by traditional Chinese medicine, thus improving the clinical effect.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.
