Objective To compare the difference of pregnancy outcomes between women who had a history of recurrent spontaneous abortion ( RSA) and women who were primigravida. Methods A case-control study was carried out. A total of 98 cases with a history of RSA and giving birth in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January of 2010 to September of 2014 served as the case group, while 98 primigravida giving birth at the same period in the same hospital were randomly selected as controls. The information collection form was designed following literature review before the research. All of the available data, including maternal demographic, reproductive information, medical history and present pregnancy outcomes, were collected from in-patient medical records. The number of valid information forms in case group was 91 and was 94 in control group after excluding the forms with incomplete data. The data was analyzed with SPSS 16.0 software. Results Univariate analysis results showed that maternal age, marital status, distribution of ABO blood groups, the history of infertility, clinical manifestation of threaten abortion, miscarriage treatment during pregnancy, medication of Zishen Yutai Pills for preventing miscarriage, time of delivery, adverse pregnancy outcome, and newborn sex were statistically significant different between the two groups ( P<0.05) . Logistic regression analysis results showed that there were significant differences in 5 factors between the two groups. Maternal age ( OR=1.466, 95%CI=1.267-1.698) , medication of Zishen Yutai Pills for preventing miscarriage ( OR=4.484, 95%CI=1.073-18.519) , and adverse pregnancy outcome ( OR=8.850, 95%CI=2.994-26.316) were the risk factors of RSA. Set blood type O as the classification reference, blood type A was a protective factor ( OR=0.259, 95%CI=0.088-0.765). And newborn sex was another protective factor of RSA ( OR=0.336, 95%CI=0.139-0.813). Conclusion Older women or women with blood type O are more likely to suffer from RSA than women with blood type A. Comparing with primigravida, women who had a history of RSA are more willing to accept medication of Zishen Yutai Pills for miscarriage, and women giving birth of a boy are more likely to have RSA and thereatened abortion, having high risk of adverse pregnancy outcomes particularly for the increase of gestational diabetes incidence.

Objective To evaluate the effect of health education combined with lung function test on smoking cessation in smoking sanitation workers. Methods Sixty-nine sanitation workers who smoke were divided into two groups by using the table of random number, routine group (n=35) and lung function test group (n=34). The routine group was given health education. According to the lung function, those in the lung function test group were divided into normal lung function group (19 cases) and abnomal lung function group (15 cases) who received both health education and lung function test. Success rate of smoking cessation and the relapse rate were compared at 2 and 6 months follow-up. Results At 2 and 6 months follow-up, the smoking cessation rates of routine group were [10(29%), 4(11%)], which were lower than those of the normal lung function group [7(37%), 3(16%)], the differences were not statistically significant (P>0.05). The smoking cessation rates of routine group were lower than those in abnormal lung function group[11 (73%), 10(67%)] (P<0.05). The smoking cessation rates of the normal lung function group were significantly lower than those of abnormal lung function group (P<0.05). The relapse rate of routine group[6(17%) and the normal lung function group[4(21%)]at 6 months follow-up were not significantly different. The relapse rate of the normal lung function group and that of abnormal lung function group were not significantly different. Conclusion Health education combined with lung function test could help smokers with abnormal lung function to give up smoking successfully.

Objective To improve the establishment of severe acute pancreatitis model in rat. Methods 36 Sprague-Dawley rats were randomly divided into experiment or shame operation group(n=18,each). Severe acute pancreatitis was induced by injection of 4% sodium taurocholate through puncturing common bile duct with a fine needle, puncture hole was closed by medical sealant glue. Ascites volume and blood amylase were measured at 3, 6 and 12 hours after injection. Gross and histological changes of pancreas were evaluated by a scoring system. Results Pancreatic changes in the experiment group was hemorrhagic and necrosis.The ascites volume(8.52±1.05)ml,serum amylase activity(5247.17±547.07)u/L, gross and histological scores(13.6±3.92) in experiment group was significantly higher than ascites volume(1.21±0.32)ml,serum amylase activity(1289.5±176.67)u/L, gross and histological scores((0.83±0.58) in shame operation group at every time point(P<0.05). Conclusions Combined injection through common bile duct and medical sealant glue in the experiment can minimize the trauma and simplize the procedure. This method produces a reliable model with high success rate and it is an ideal severe acute pancreatitis animal model.

Objective To explore the effects of glutamine (Gln) on tumor necrosis factor-alpha (TNF-α),interleukin-6(IL-6),and interleukin-10 (IL-10) in rats with severe acute pancreatitis (SAP).Methods 54 Sprague-Dawley rats were randomly divided into 3 groups ( n =18 for each group):Gln treatment group ( Gln),SAP model group (SAP),and negative control group (NC).SAP was induced by injection of 4％ sodium taurocholate through common bile duct with a fine needle and the puncture hole in the bile duct was closed by medical sealant glue.Sham operation was performed in the rats of NC group.Rats in Gln group received Gln injection and rats in SAP group and NC group received normal saline instead of Gln.Ascites volume and blood amylase were measured at 3,6 and 12 hours after injection and plasma cytokines were detected by enzyme-linked immunosorbent assay (ELISA).Gross and histological changes of pancreas were evaluated by a scoring system.Results The ascites volume,serum amylase level,gross and histological scores,TNF-α level,and IL-6 level were significantly higher in SAP group than in NC group at each time point(P＜0.05).IL-10 level was significantly higher in SAP group than in NC group at 3 hour point(P＜0.05).The ascites volume,serum amylase level,and gross and histological scores were significantly lower in Gln group than in SAP group at the time point of 3 hour and 6 hour after injection( P ＜ 0.05 ).Level of TNF-α and IL-6 was significantly lower in Gln group than in SAP group at each time point( P ＜0.05 ).IL-10 level was lower in Gln group than in SAP group at 3 hour point( P ＜0.05 ).Conclusion Gln is effective in SAP treatment by decreasing the serum level of proinflammatory cytokine and ameliorating the pathological damage of pancreatic tissues in rats.

BACKGROUND: The low survival rate of neuron cells is one of the main mechanisms of stem cell allograft, which might lead to the failure of allograft. Nuclear factor-KB (NF-kB) is one of main transcription factors for cell signaling transduction and participates in call proliferation and differentiation.OBJECTIVE: To study the differentiation of muscle-derived stem cells (MDSCs) into neuron-like cells induced by ciliary neurotrophic factor (CNTF) and Compound Salvia Miltiorrhiza Injection in vitro, and the expression of NF- kB.DESIGN, TIME AND SETTING: The experiment at cell molecular level was performed at the Oral Science Laboratory of the Second Affiliated Hospital of Liaoning Medical College from March to May 2008.MATERIALS: A total of 10 Sprague Dawley neonatal rats aged 7 days were supplied by Experimental Animal Center, Liaoning Medical University. CNTF (Sigma, USA) and Compound Salvia Miltiorrhiza Injection (Chiatai Qingchunbao Pharmacantical Co.,Ltd., China) were used in this study.METHODS: Rat MDSCs were harvested in vitro, pudfied by differential adherence and enzyme digestion, and incubated in 6-well plate. Samples in the induction group were incubated in DMEM containing CNTF for 24 hours. The medium was changed.Subsequently, samples were dnsed three times, and then incubated in serum-free DMEM supplemented with Compound Salvia Miltiorrhiza Injection for 5 hours. Samples in the control group were treated with serum-free DMEM.MAIN OUTCOME MEASURES: Neurofilament protein and NF-KB inhibitor protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Westem blotting.RESULTS: No neurofilament protein expression was found in MDSCs before induction, and neurofilament protein-positive MDSCs were detected following induction. Results of gel electrophoresis and Westam blot showed that no significant differences in NF-kB inhibitor protein expression were determined in the control group, and NF-kB inhibitor protein expression was significantly decreased in the induction group after induction.CONCLUSION: CNTF and Compound Salvia Miltiorrhiza Injection could inhibit the activation of NF-kB and induce the differentiation of MDSCs into neuron-like cells.Zeng XY, Wang W, Sun L, Zhang L, Zeng LD.Differentiation of muscle-derived stem cells into neuron-like cells induced by ciliary neurotrophic factor and Compound Salvia Miltiorrhiza Injection in vitro.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2009;13(27): 5336-5340.

Objective To investigate the effect of ectodysplasin A (EDA‐A1) gene of hypohidrotic ectodermal dysplasia on pro‐liferation and cell cycle of human umbilical vein endothelial cell (ECV304). Methods Recombinant eukaryotic expression vectors pcDNA3. 1(‐)‐EDA‐A1‐M /W (mutant, M and wild, W) containing the coding sequence were transected into ECV304 cells. EDA‐A1 gene was amplified by reverse transcription polymerase chain reaction (RT‐PCR), and the protein was detected by Western blot. Cell viability and cycle distribution were invested by MTT and Flow cytometry (FCM ). Results The EDA‐A1 gene and pro‐tein were detected respectively by RT‐PCR and Western blot in ECV cells transfected with pcDNA3. 1(‐)‐EDA‐A1‐M /W, but not in ECV cells transfected with plasmid pcDNA3. 1(‐) and cells without transection. And also, compared with control groups, EDA‐A1 gene mutant significantly decreased proliferation of ECV cells and its inhibition rate was 45. 70% ( P < 0. 01), whereas wild EDA‐A1 gene did not cause such growth inhibition (P> 0. 05). A significant increase of the G0 /G1 and S fraction was seen in the ECV cells of mutant group, compared with wild group with an accumulation in S phase and a concomitant decrease in G2 /M phase population (P< 0. 05). Conclusion Mutant and wild EDA‐A1 gene may have distinct biological functions on proliferation and cell cycle distribution of cultured human umbilical vein endothelial cell.
