Chinese Journal of Pathophysiology 2000;0(11):-
AIM: To investigate the effects of c-fos antisense oligoneuleotide and p21 genetic transfection on the intimal proliferation of venous autografts. METHODS: The external jugule veins were autografted into common carotid arteries in the same side in 20 New Zealand rabbits, which were divided evenly into experimental and control group randomly. The transplanted veins of experimental group were immersed in the adenovirus - mediated p21 gene solution for 15 minutes just before anastomosis and coated with c-fos antisense oligoneucleotide glue gel just after anastomosis, while the control was only treated with empty vector. The transplanted vascular sample were taken at 2 weeks after operation. The intimal thickness (IT), degree of restenosis (DR), expression of proliferating cell nuclear antigen (PCNA), quantity of VSMC were determined by immunohischemistry. RESULTS: The IT , DR and expression of PCNA, VSMC were decreased, compared to control group. CONCLUSION: Transfection of c-fos antisense oligoneuleotide and p21 gene inhibits the intimal proliferation of venous antografs. [
4.Research Progress of a Novel Pro-apoptosis Gene PNAS-4 in Gene Therapy and Its Molecular Mechanism Hypotheses.
Journal of Biomedical Engineering 2015;32(6):1380-1384
PNAS-4 is a novel pro-apoptosis gene identified latetly. In recent years, there has been a large number of research reports on the basic studies about PNAS-4 in cancer gene therapy and gene therapy of PNAS-4 alone or combined with chemotherapy or radiotherapy manifested a good application prospect, but its molecular mechanisms to promote apoptosis is not clear yet. In this paper, recent research about PNAS-4 in cancer gene therapy is briefly reviewed, and recent hypotheses on its molecular mechanisms to promote apoptosis are especially elucidated. Based on its newly identified characteristics of structural domain, we made a point that PNAS-4 might regulate functions of some target protein related to apoptosis by deSumoylation as a new deSumoylating isopeptidase, and consequently promote apoptosis.

5.The Antitumor Effects of Mice Peritoneal Macrophages Transferred IL-2 and IFN-Y Gene in vivo
Chinese Journal of Cancer Biotherapy 1994;0(01):-
The eukaryotic expression vector pREP-8-IL-2 or and pREP-8-IFN-? was injected i.p. into mice by calcium phosphate coprecipitation method and IL-2 gene or IFN-? gene was successfully transfected into peritoneal M?s whose expression products could enhance the cytotoxicity of M?s, which secrete some TNF, IL-1 and NO, activate the nonspecific immunity and inhibit the growth of tumor effectively. In particular, IL-2 gene in combination with IFN-? gene transfection were successfully transfected into peritoneal M?s whose high expression products not only significantly enhance the M?s cytotoxicity and made it secrete high level TNF, IL-1 and NO, but also activated the CTLs of spleen and initiated specific immunity and nonspecific immunity . This would produce synergic antitumor effects. The results showed that IL-2 and IFN-? gene transfection produced more antitumor effects than IL-2 or IFN-? gene transfection alone.

Chinese Journal of Tissue Engineering Research 2017;21(27):4416-4422
BACKGROUND: The incidence of deep venous thrombosis of the lower extremity after spinal surgery remains controversial, and its prevention is still under discussion.OBJECTIVE: To summarize the progress of the prevention of the deep venous thrombosis after spinal surgery.METHODS: The domestic and foreign related literature about the deep vein thrombosis after the spinal surgery, which was filtrated from CNKI and PubMed databases, were searched for the articles concerning the prevention of the deep venous thrombosis after spinal surgery published from January 1993 to January 2016.Finally, 41 eligible articles were included, and the prevention methods, risk factors and incidence were summarized.RESULTS AND CONCLUSION: (1) With the technology and medical equipment development, more novel technologies and biomaterials are extensively applied in spinal surgery; meanwhile, complex and difficult surgeries,big surgical trauma and prolonged operation time all increase the risk of deep venous thrombosis of the lower extremity;thereafter, the incidence is on a rise. (2) The prevention methods of deep venous thrombosis have been improved, and the grading of prevention becomes more sufficient. (3) During venipuncture and injection, upper extremity should be selected firstly, so as to avoid damage to the lower extremity veins. (4) The following studies should concentrate on understanding the epidemic characteristics of deep venous thrombosis of the lower extremity after spinal surgery, and confirming the best prevention time, as well as effective drugs and physical measurements.
10.Estimate of the Amount of Blood Loss after Cesarean Section by Different Methods and Analysis the Related Risk Factors of the Blood Loss More than 500 ml
Journal of Practical Obstetrics and Gynecology 2017;33(6):461-464
Objective:To choose a best method of estimating the amount of blood loss after cesarean deliveryby comparing of three methods,to analyze the related factors of the amount of the blood loss more than 500ml after cesarean section.Methods:We collected the clinical data of the patients who were accepted cesarean delivery and treated in our hospital between January 2014 and December 2014.We estimate the amount of blood loss by different methods(including visually estimated,hematocrit (HCT) change and formula).Based on the formula method as the gold standard,we analyze the risk factors of the patients whose blood loss were more than 500 ml.Results:Among the 583 patients,using the method of visually estimated,there were 23 cases whose blood loss were more than 500 ml(3.95%),using the method of formula,there were 133 cases whose blood loss were more than 500 ml (22.81%),using the method of HCT change,there were 116 cases whose blood loss were more than 500 ml(19.90%).The incidence of patients whose blood loss were more than 500 ml between HCT change and formula method showed no significant difference(P > 0.05),but the incidence by visually estimated method was less than the two other methods (P < 0.05).We found the value of HCT change was a statistically significant positive correlation with the amount of blood loss more than 500ml.When the blood loss was more than 500 ml,the accuracy and sensitiveness of HCT method were significantly higher than those of visually estimated method(76.69%,87.93% vs 12.78%,73.91%,respectively).Abnormal labor,uterine leiomyoma,placental factors,and macrosomia were risk factors of cases whose blood loss more than 500ml.Conclusions:HCT method is similar in accessing the blood loss after cesarean section with formula method,especially in the cases whose blood loss was more than 500 ml;HCT method is more convenient than formula method,and more accurate than visually estimated method.HCT method can be used as the standard for estimating blood loss initially,and formula method should be used as the method for estimating the blood loss accurately.Patients with macrosomia and abnormal labor are more likely to occur massive hemorrhage after cesarean section.
