Objective:Toclone the OPGgene ofhuman beingand construct its recombinant adenovirus and then observe its effects on the differentiation of bone marrow stem cells(BMSCs).Methods:The cDNAs of human OPG in hepatic tissue were obtained by using RT-PCR method.The cDNAs then were recombined with competent homologous cells to form the AdOPG and the shuttle vector was used during this stage.The rabbit BMSCs were isolated and cultured in vitro,and were infected with AdOPG.The OPG expression of BMSCs was identified by RT-PCR and Western blot.The expression of ALP was detected by chromatometry and ALP dyeing five days after the infection.Results:The OPG gene of human being was successfully cloned and its sequence consistent with the Gene bank.The titre of constructed AdOPG can reach 109 efu/ml.The ALP activity of BMSCs was(21 024?507)IU five days after the infection of AdOPG,whereas the value was(3 079?89)IU in the control group and(2 156?78)IU in the blank control group.Conclusion:The OPG can induce the osetogeinc differentiation of BMSCs.

Biorefinery that utilizes renewable biomass for production of fuels, chemicals and bio-materials has become more and more important in chemical industry. Recently, steam explosion technology, acid and alkali treatment are the main biorefinery treatment technologies. Meanwhile, low temperature plasma technology has attracted extensive attention in biomass refining process due to its unique chemical activity and high energy. We systemically summarize the research progress of low temperature plasma technology for pretreatment, sugar platflow, selective modification, liquefaction and gasification in biomass refinery. Moreover, the mechanism of low temperature plasma in biorefinery and its further development were also discussed.

Objective To observe the therapeutic efficacy of centro-square needling plus stuck needling with lifting-thrusting manipulations in treating the injury of medial collateral ligament (IMCL) of knee joint. Methods Seventy-eight patients with IMCL of knee joint were randomized into a treatment group of 40 cases and a control group of 38 cases. The treatment group was intervened by centro-square needling plus stuck needling with lifting-thrusting manipulations, while the control group was by local anesthesia treatment. The therapeutic efficacies were compared between the two groups. Results The total effective rate was 97.5% in the treatment group versus 81.6% in the control group, and the difference was statistically significant (P＜0.05). Conclusion Centro-square needling plus stuck needling with lifting-thrusting manipulations is an effective way in treating IMCL of knee joint.

Objective To develop an informatized continuous education system for theater nurse based on PDCA theory.Methods The system was gifted with the functions of learning planning, learning execution, learning checking, data management and system management based on PDCA theory, informatized technology and other learning systems.Results The system behaved well in overall flow and configuration, man-machine interaction and application, which facilitated the nurses to learn with fragmented time.Conclusion The nursing continuous education is enhanced greatly with the system.

OBJECTIVE: To provide reference for rational use of drugs. METHODS: 200 ADR cases induced by TCM injection from Huizhou were analyzed retrospectively. RESULTS: Of total 200 ADR cases, 133 cases were male, which was significantly higher than females in 67 cases(P

Objective To observe the expression of intercellular adhesion molecule 1(ICAM-1)and vascular cellular adhesion molecuh 1(VCAM-1)in placenta in patients with hypertensive disorders in pregnancy,investigate their roles in patients with hypertensive disorders in pregnancy and correlation.Methods Fifty-two patients with hypertensive disorders in pregnancy(disease group)were collected,including 11 csses with gestational hypertension(GH),18 cases with mild pre-eelampsia(MP)and 23 cases with gevere pre-eclampsia(SP),26 cases of normal pregnant women as control group.Immunohistochemistry and image analytical technique were employed to show the expression of ICAM-1 and VCAM-1.Results The quantities of ICAM-1 and VCAM-1 expressed in the placental vascular endothelial cell were 78.85%(41/52)and 75.00%(39/52)in disease group,26.92%(7/26)and 23.08%(6/26)in control group,there was a significant difference between the two groups(P<0.01).and those in SP patients[100.00%(23/23)and 100.00%(23/23)]were higher than those in MP patients[77.78%(14/18)and 72.22%(13/18)]and GH patients[36.36%(4/11)and 27.27%(3/11)](P<0.05 or<0.01).The quantities of ICAM-1 and VCAM-1 expressed in the placental villous syncytlotrophoblast were cell 38.46%(20/52)and 44.23% (23/52)in disease group,100.00%(26/26)and 96.15%(25/26)in control group,there was a significant difference between the two groups(P<0.01),and those in SP patients[8.70%(2/23)and 13.04%(3/23)]were lower than those in MP patients[44.44%(8/18)and 50.00%(9/18)]and GH patients[90.91%(10/11)and 100.00%(11/11)](P<0.05 or<0.01).Conclusion Abnormal expression of ICAM-1 and VCAM-1 in the placental vascular endothelial and villous syncytiotrophoblast cell in patients with hypertensive disorders in pregnancy may participate in pathogenic process of vascular endothelial damage of hypertensive disorders in pregnancy.

Objective To explore the common complications and methods of treatment in the malignant obstruction of upper alimentary tract with stent insertion. Methods With interventional procedure under fluoroscopic guidance fourteen self expanding stents were implanted in twelve patients, including nine with strictures or obstructions of esophagus, three with obstructions of gastroduodenum. Of the fourteen, nine were coated stents and five were uncoated stents. Results All stents were implanted successfully, but complications after the procedure occurred sometimes. There complications included: 1. Food bolus obstructed in three patients. 2. Chest pain occurred in four patients. 3. Tumour overgrowth or hyperplasia of granulation tissue in three patients caused restenosis of gastrointestinal tract. 4. Stent replacement in three patients. 5. Hemorrhage occurred in two patients (over 300 ml) causing threat to life. Conclusions The implantation of self expanding stent is a simple and effective method offering good palliation for upper alimentary tract obstructions. The complications shoud be treated correctly.
