Chinese Journal of Cancer Biotherapy 1994;0(01):-
Objective:To investigate the inhibitory effect of antisense oligodeoxynucleotide (ASODN) targeting survivin gene on gastric cancer cell line SGC-7901. Methods: Cultured SGC-7901 cells were divided into 6 groups: control group, lipofectin group, oligodeoxynucleotide(ODN) group, 1?10-5mol/L ASODN group, 3?10-5mol/L ASODN group and 5?10-5mol/L ASODN group. After incubated with ASODN, the expression of survivin mRNA in the SGC-7901 cells was examinated by PCR; the apoptosis of SGC-7901 cells was studied by the morphological observation using inverted microscope, electron microscope, flow cytometry and DNA agarose electrophoresis; telomerase activity was determined using PCR-based TRAP (telomere repeat amplification protocol) assay; MTT assay was used to study the inhibitory effect of ASODN on the proliferation of SGC-7901 cells. Results: ASODN obviously inhibited the expression of survivin mRNA in the SGC-7901 cells. The apoptotic rate of gastric cell was significantly increased after incubated with ASODN ([7.01?0.21]% vs [25.0?0.52]%, P

Chinese Journal of Tissue Engineering Research 2007;0(41):-
A great progress has been achieved in research on repair of nerve functional recovery following spinal cord injury because of the development of nerve tissue engineering.As an important part of nerve tissue engineering,cell scaffold is divided into natural biomaterials,synthetic materials and composite materials.Besides,nanotechnology has been applied to study scaffolds.However,there are many problems in the application of cell scaffold and further study is needed.With the continued development of biotechnique and cross-correlated technique,the cell transplantation scaffold will make more effect on repair of spinal cord injury.
4.Influence of Heat and Moisture Exchanger Filter on Temperature of Inspiratory and Endotracheal Gas
Chinese Medical Equipment Journal 2003;0(10):-
Objective To investigate the influence of heat and moisture exchanger filter(HMEF)on the temperature of inhaled and endotracheal gas during mechanical ventilation. Methods Thirty patients (ASAI-II) were selected and divided randomly into 2 groups: control group and HMEF group. The temperature of inhaled gas was monitored with hygrothermograph and the temperature of endotracheal gas was monitored with temperature probe. Baseline values were set at the moment of intubation and then the values were recorded at the first hour after intubation and the second hour after intubation. Results With the increase of the mechanical ventilation time, the temperature of inhaled and endotracheal gas decreased significantly in control group and increased significantly in HMEF group; The temperature of both inhaled and endotracheal gas in HMEF group were significantly higher than that in control group at the moment of the first hour after intuba- tion and the second hour after intubation; There was correlation between the temperature of inhaled gas and the temperature of endotracheal gas at the moment of intubation, but it was not the same at the moment of the first hour after intubation or the second hour after intubation. Conclusion HMEF can make the cold inhaled gas warmer when it reached the trachea; Temperature probe may be better than hygrothermograph for monitoring the temperature of trachea.

Chinese Journal of Medical Education Research 2016;15(12):1272-1275
Peripheral nerve block technique is one of the basic skills necessary to residents and it is also one of the difficult points in the resident standardized training in the department of anesthesiology. In order to maximize the learning effect of the anesthesia professional residents in the case of limited number of cases, we need to constantly enrich the teaching technologies and teaching methods. Human 3D anatomy is used for theory teaching to maintain comprehension of nerve anatomy; Ultrasound-guided nerve block technique and ultrasound simulation training are used for nerve block practice to improve nerve block skills;Problem-based learning teaching method is introduced in nerve block cases to increase the residents' ability of clinical cases management.

Chinese Journal of cardiovascular Rehabilitation Medicine 2016;25(2):185-188
Objective:To observe therapeutic effect and influence of rosuvastatin on levels of interleukin (IL)-35 and nu- clear factor-κB (NF-κB)in patients with coronary heart disease (CHD).Methods:A total of 85 CHD patients were randomly divided into rosuvastatin group (n=43,received rosuvastatin calcium therapy based on routine treatment)and atorvastatin group (n=42,received atorvastatin calcium therapy based on routine treatment),both groups were treated for eight weeks all.Cardiac index (CI),cardiac output (CO),left ventricular ejection fraction (LVEF),left ventricular end-diastolic dimension (LVEDd),serum levels of IL-35 and NF-κB,and total effective rate were measured and compared be- tween two groups before and after treatment.Results:Compared with before treatment,there were significant rise in CI, CO,LVEF and IL-35 level,and significant reductions in LVEDd and NF-κB level in both groups after treatment (P<0.05 or<0.01).Compared with atorvastatin group after treatment,there were significant rise in CI [(3.54±0.72)L· min-1 ·m-2 vs.(3.88±0.83)L·min-1 ·m-2 ],CO [(3.78±0.89)L/min vs.(4.94±0.96)L/min],LVEF [(56.20 ±9.71)% vs.(63.48±14.15)%]and serum IL-35 level [(96.26±24.33)pg/ml vs.(106.92±27.26)pg/ml],and sig- nificant reductions in LVEDd [(4.71±0.89)cm vs.(4.36±0.75)cm]and NF-κB level [(21.51±5.01)ng/ml vs. (18.32± 5.17)ng/ml]in rosuvastatin group,P<0.05 all.Total effective rate of rosuvastatin group (95.35% vs. 76.19%)was significantly higher than that of atorvastatin group,P<0.05. Conclusion:Rosuvastatin possesses more sig- nificant therapeutic effect than that of atorvastatin on coronary heart disease,and its heart protection effect besides lipid lowering may be related to regulating levels of interleukin-35 and nuclear factor-κB.
10.Hemorheologic changes during acute lung injury induced by oleic acid on dogs
Chinese Journal of Pathophysiology 1986;0(03):-
Erythrocyte aggregation and related parameters were observed in this study.Erythrocyte aggregation index, hematocrit and fibrin fibrinogen degradation products in-creased significantly at 5 minutes after oleic acid injection. Erythrocyte electrophoretic timein native plasma delayed obviously at 5 minutes after oleic acid injection, whereas that inPBS altered very little. The concentration of plasma calcium and erythrocyte intracellularmagnesium decreased at 5 minutes, while plasma magnesium increased. The stepwise reg-ression analysis suggested that during lung injury the parameters that have greatest effect onerythrocyte aggregation were the change of hematocrit, erythrocyte intracellular magnesiumand negative charge of erythrocyte surface.
