Purpose:To investigate the antitumor effect of 5-fluorocytosine/cytosine deaminase (5FC/CD) suicide gene system combined with heat shock protein 70 peptide complexes(HSP70-PC) tumor vaccine.Methods:5-FC was administrated intraperitoneally after recombinant adenoviruses carrying E.coli CD gene were injected into murine tumor tissue. At the same time,mice bearing tumor were inoculated s.c. with HSP70-PC. Results:The combined therapy led to reduction in tumor growth, and complete tumor regression was observed in 70% of the mice. After the combined therapy, the tumor tissue showed more CD + 4 and CD + 8T cells infiltration, and the murine CTL activities increased significantly. Conclusions:The therapy combining 5-FC/CD system with HSP-PC tumor vaccine is very effective in murine gastric cancer, and has potential for clinical usage.

Objective To investigate the effect of pulmonary surfactant on neonatal with acute respiratory distress syndrome.Methods98 cases with neonatal respiratory distress syndrome inthe fourth hospital of Ningbo were randomly divided into experimental group and control group, 49 cases in each group.All patients were given warm, anti infection, and maintain the internal environment stability, prevention of bleeding and other conventional treatment.The control group were treated with mechanical CPAP, the experimental group were given pulmonary surfactant 70mg/kg, concentration is 35mg/mL.Pulmonary surfactant was injected slowly by tracheal intubation at supine, lateral(left, right) and semi recumbent position.The drug was distributed evenly in the lung of the patients who were given the drug 1-2 times.Respiratory frequency (RR), pH, oxygen partial pressure (PaO2), partial pressure of carbon dioxide (PaCO2) levels and the incidence of complications, clinical effective rate of the tthe two groups were observed and compared.ResultsCompared with pre-treatment, RR and PaCO2 levels were decreased, pH and PaO2 levels were increased after treatment in the two groups, the differences were statistically significant (P<0.05);compared with the control group, RR, PaCO2 level were lower, pH and PaO2 levels were higher in the experimental group, the differences has statistical significance (P<0.05);compared with the control group, the experimental groupwith a low incidence of complications, clinical effective rate is higher, the difference was statistically significant (P<0.05).ConclusionPulmonary surfactant can reduce the respiratory frequency in neonatal with acute respiratory distress syndrome, improve arterial blood gas levels, which get better clinical curative effect.

Objective To provide a reference for local best practice information sheet by way of analyzing the status quo of adult peripheral venous catheters nursing and maintenance.Methods Systematically analyzing the related 487 documents met the inclusion criteria in CBMdisc,CNKI Database and WanFang Database from the year of 1990 to 2013 by biliometric analysis methods.Results The number of documents,rising year after year,stood mainly in nursing journals,of which the majority authors are from Guangdong [10.3％(50/487)],Anhui [9.0％(44/487)] and Hubei [7.6％(37/487)].50.3％ (245/487)of the documents did not refer in particular to the object.The three major research concerns are the prevention and treatment of complications[80.9％(394/487)],cannulation [23.6％(115/487)] and maintenance [19.9％ (97/487)].Conclusions Peripheral venous catheter cannulation and maintenance has gained widespread attention among the domestic clinical staffs,but the overall quality of articles concerning these aspects is not high.High-quality research papers are expected to provide better evidence for local best practice information sheet.

[Objective] To observe the dynamic changes of circulating immune complex (CIC) in monkeys infected by simian immunodeficiency virus (SIV). [Methods] Agglutination test of complement-sensitized yeast cell was used to determine the serum CIC level in 30 cases of monkeys, which were infected with SIVmac251 and sampled in different time-points after infection. Sixty-eight cases of normal monkeys were also examined as controls. [Results] After SIV infection, CIC can't be detected in all 30 monkeys until the 4th week, the total positive rate being 30% . In the 8th week, CIC were detected in 46.7% of these monkeys and then declined gradually in the following 12 weeks. Since the 20th week, the CIC in these monkeys maintained lower liter and lower positive rate which was close to that of the normal monkeys (about 10%). [Conclusion] CIC appeared and increased during the primary SIV infection and declined accompanying with the virus clearance from the circulalion. The formation of CIC may not benefit to the control of virus replication and the induction of anti-virus immunity; CIC has a role in the pathogenesis after SIV infection.

Objective: To study changes of ultrastructure of atrial endothelial cells during acute atrial fibrillation (AF) in canines, and explore the possible mechanism of AF left atrial thrombosis. Methods: A total of 16 healthy adult mongrel canines were randomly and equally divided into blank control group (only received thoracotomy without pacing) and rapid atrial pacing (RAP) group (established acute AF model). Myocardial tissue of left and right appendage were taken from two groups and received hematoxylin eosin (HE) staining, then myocardial cell morphological changes was observed under ordinary light microscope; morphological changes of appendage endothelial cells was observed under electron microscope. Results: (1) Paroxysmal AF was successfully induced in all canines of RAP group; (2) There were no significant difference in morphology of appendage and endocardial tissue under ordinary light microscope between two groups; 3. Under transmission electron microscope, endothelium cell of appendage tissue presented defect of different extent, and some shedding in RAP group; while endothelial cell layer was complete with absence of necrosis and shedding in blank control group. Compared with blank control group, there was significant rise in endothelial cell incompleteness (12.5% vs. 75.0%) in RAP group, P=0.041. Conclusion: When acute atrial fibrillation occurs, endothelial cell ultrastructure has already changed, which may be related to thrombosis adhered to wall during atrial fibrillation.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

Objective To establish and identify the induced pluripotent stem cell(iPSC) line reprogrammed from human umbilical cord mesenchymal cells(HuMSCs).Methods HuMSCs were cultured by adhesion method,and OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 were transfected into HuMSCs with lentiviral victor to reprogramme HuMSCs into iPSC.Morphological observation,pluripotency genes (SOX2,TDGF1,THY-1,OCT4,REX1 and TERF1) expression,alkaline phosphatase detection,karyotype analysis,embryonic stem cells (ESC) specific proteins (NANOG,OCT4,SSEA-4,TRA-1-81) immunofluorescence staining,differentiated into teratomas in vivo(inject the iPSC into SCID mice) and embryniod bodies in vitro were performed to exam the pluripotency of the iPSC.Results Four days after being infected by lentivirus,the HuMSCs became round-shape; 10 days after infection,some embryonic stem(ESC)-like colonies appeared.Fourteen days after infection,picked up the regularly shaped colonies and cultured several passages.About 1.25％ HuMSCs were reprogrammed into iPSC.The iPSC presented clone-like growth like ESC.All the cells were positive to alkaline phosphatase staining and expressed the pluripotency genes.The iPSC also expressed the ESC specific proteins,and karyotype analysis showed normal chromosome caryotype (46,XY).Furthermore,the iPSC could form embryoid bodies in vitro,expressed alpha fetoprotein(AFP),smooth muscle actin(SMA) and β-tubulin.The iPSC could alsoform teratomas in vivo.Conclusion OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 can reprogram HuMSCs into iPSC efficiently.

Objectives To investigate the consumption of carbohydrate and distribution of dietary glycemic load (GL) in Chinese adults. Method Data from China National Nutrition and Health Survey in 2002 were used for this analysis. Dietary glycemic load was calculated as a function of glycemic index, carbohydrate content and frequency of intake of individual foods. Results Dietary glycemic load was contributed by 92% from cereals. People with low dietary GL /4184 kJ tended to consume more fat, less cereals, and less carbohydrates. The prevalence of overweight and obesity was higher in those with low GL/4184 kJ, especially in urban residents. Conclusion People with low GL/4184 kJ tend to consume more fat, less cereals, less carbohydrates. The situation in urban residents is more serious. Based on factors including cereals intake, energy contribution from fat and carbohydrates, prevalence of malnutrition, overweight and obesity. A proposed range for dietary GL /4184 kJ in Chinese adults can be 80~120.
