Journal of Chongqing Medical University 2003;0(05):-
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.
3.Low temperature plasma technology for biomass refinery.
Chinese Journal of Biotechnology 2014;30(5):743-752
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.

4.Contrast in respiratory mechanics and blood gas between bronchial blocker and double lumen tube in one lung ventilation
Chinese Journal of Postgraduates of Medicine 2011;34(15):4-6
Objective To compare the influences between bronchial blocker (BB) and double lumen tube (DLT) in respiratory mechanics and blood gas in one lung ventilation. Methods Thirty-six patients undergoing pulmonary lobectomy or radical operation of esophageal carcinoma were randomized into group BB (17 cases) and group DLT (19 cases). In group BB,BB was intubated under the guidance of a fibreoptic bronchoscope after intubation of single lumen tube; while in group DLT, the position of the tube was confirmed using fibreoptic bronchoscopy after intubation. The peek airway pressure (Pmax) and pulmonary dynamic compliance (CLdyn) during double lung ventilation and one lung ventilation were recorded in recumbent position. Blood samples were taken from, radial artery 20 min after one lung ventilation for blood gas analysis,partial pressure of oxygen in artery(PaO2), partial pressure of carbon dioxide in artery(PaCO2), saturation of arterial blood oxygen (SaO2) were recorded. Results No significant difference was found in Pmax and CLdyn between two groups during double lung ventilation,but Pmax was significantly lower in group BB [(21.00 ± 3.59) cm H2O,1 cm H2O = 0.098 kPa] than that in group DLT [(26.89 ±4.21) cm H2O] (P<0.05), and CLdyn was greater in group BB [(28.10 ±6.24) ml/cm H2O] than that in group DLT [(24.00±7.13) ml/cm H2O ] (P < 0.05); there were no significant differences in PaO2, PaCO2, SaO2 betweentwo groups during one lung ventilation (P> 0.05). Conclusion The influence to respiratory mechanics in one lung ventilation is smaller using BB than using DLT, BB has blocker well applicable value in clinics.

Journal of Interventional Radiology 1994;0(03):-
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.
