Objective To investigate the effect of multidisciplinary intervenient on survival of patients with malignant tumor. Methods Six hundred and thirty-nine malignant tumor patients were randomly assigned to the intervenient and the control group. A total of 584 completed the follow-up study. The intervenient group received comprehensive treatment for 2 years,while the control group was in a process of self-rehabilitation. The 2-year survival rate was compared between the groups by using Cox proportional hazard model. Results The 2-year survival rate was 94. 74% (108/114) or 80. 67% (121/150) in II stage patients of the intervenient or control group, respectively ( P < 0. 01 ) . The 2-year survival rate was 88. 03% (163/177) or 82. 8% (184/222) in early and medium stage patients of the intervenient or control group,respectively(P <0. 01). Conclusion The multidisciplinary intervenient may help to improve the 2 year survival of early or moderate stage malignant tumors.

Objective To explore the perinatal outcome of vaginal birth after cesarean (VBAC) in women with advanced age.Methods Totally 2 587 women delivered after one or two prior cesarean sections (gestational age≥28 weeks) in the First Affiliated Hospital of Kunming Medical University from July 2013 to February 2017.909 trial of labor after cesarean(TOLAC) cases of singleton pregnancy with one prior cesarean section were studied retrospectively.According to the age,of the 909 TOLAC cases,237 were the advanced age group,and 672 cases were the low age group.The maternal and neonatal outcomes between the two groups were compared.Results The percentage of TOLAC in women with advanced age was 32.4％ (237/731),and VBAC rate was 88.2％ (209/237).The percentage of TOLAC in younger women was 36.2％ (672/1 856),and VBAC rate was 82.4％ (554/672).The difference of the TOLAC rate between the two groups was not significant (P＞0.05),and the VBAC rate of the advanced age group was higher than the low age group (P＜0.05).In the comparison of the two groups,the proportion of bachelor degree or above(55.7％,132/ 237),the prepregnancy BMI (22.4±3.0) kg/m2,pregnant interval time (68.5±38.3) months,the proportion of gestational hypertension (8.4％,20/237),the proportion of gestational diabetes(34.6％,82/237) and the rate of the neonatal ICU admission (18.1％,43/237) in the advanced age group were higher than those of the low age group (P＜0.05),respectively.And there were no significant differences in the rate of postpartum hemorrhage,the rate of postpartum hemorrhage≥1 500 ml,the rate of postpartum transfusion,puerperal morbidity,neonatal birth weight,neonatal 5 min Apgar score＜7 score,umbilical artery blood pH＜7.0,neonatal tracheal intubation and respiratory distress syndrome (all P＞0.05).In all TOLAC cases,the rate of uterine rupture was 0.11％(1/909) and there was no maternal and neonatal death.Conclusion VBAC is a safe and feasible way of delivery for singleton pregnancy after one prior cesarean section in women with advanced age.

Objective To evaluate the results of surgical treatment for patients with heterotaxy syndrome and cardiac anomaly.Methods From September 2008 to October 2013,34 patients with heterotaxy syndrome underwent 46 cardiac operations at Guangzhou Women and Children Medical Center.22 were male,and 12 female.Mean age at operation was 22 months (4 months to 14 year).There were right atrial isomerism 24 cases,left atrial isomerism 10 cases.Only one had a single VSD,and others were all with complex cardiac anomaly,including complete atrioventricular canal defect 26 cases,tricuspid atresia 4 cases,mitral atresia 1 case,anomalous pulmonary venous connection 18 cases,pulmonary venous stenosis 4 cases,double superior vena cava 17 cases,and interrupted hepatic portion of the inferior vena cava 5 cases.Fontan procedure was performed in 5 patients,bidirectional Glenn in 13,Kawashima in 3,central shunt in 1,atrioventricular valve replacement in 5,and pulmonary artery banding in 5.Results There were 4 died during hospitalization.The follow-up duration was 1 month to 5 years.There were 2 died.The early to middle term mortality was 17.6％ (6/34).In the same period the mortality for 103 patients without heterotaxy syndrome underwent univentricular repair was 4.8％ (5/103).There was significant statistical difference (P ＜ 0.05).Conclusion Right heart bypass operation remains the preferred palliative procedure for patients with heterotaxy syndrome,and the eraly and middle term results were satisfied.

Objective To analyze the genetic polymorphism of GSTM1 to lung cancer patients in north Sichuan of China and compare with race from other district.Methods PCR-based technique was used to detect the genotypes of GSTM1 in lung cancer patients.Results In local lung cancer patients,the frequency of homozygous deletions(null genotype) for GSTM1 was 58.4 % (73/125).Among the patients,the frequencys of null genotype for GSTM1 were 62.5 % (20/32) in female,56.9 % (53/93) in male,56.1% (32/57)in patients with squamous cell carcinoma and 54.8 % (17/31) in patients with adenocarcinoma,respectively.The frequency of deletions of GSTM1 in lung cancer patients from north Sichuan of China is slightly exceeding those of Europe and Americas (P ＜0.05) and similar to the domestic result (P ＞0.05).Conclusion The genetic polymorphism of GSTM1 to lung cancer patients in north Sichuan of China dosen' t show distinguished feature for this district and race.

Objective To explore the diagnostic performance of 64-slice spiral CT combined with exercise treadmill test for coronary artery disease ( CAD). Methods Eighty-six patients suspected of CAD were divided into low risk group, intermediate risk group and high risk group according to estimated pretest probabilities of CAD. All patients underwent coronary angiography, 64-slice spiral CT and exercise treadmill test. With coronary artery stenosis rate >50% as positive findings, the sensitivity, specificity, positive predictive value ( PPV), negative predictive value ( NPV) and accuracy of 64-slice spiral CT and 64-slice spiral CT combined with exercise treadmill test in diagnosis of CAD were calculated. Results With coronary angiography as the "golden criteria", the sensitivity, specificity, PPV, NPV and accuracy of 64-slice spiral CT in diagnosis of CAD were 95.2% , 88.6% , 88.9% , 95.1% and 91.9% , respectively. The sensitivity of low risk group, intermediate risk group and high risk group was 100% , 100% and 92.6%, specificity was 94.4% , 94.1% and 66.7%, PPV was 80.0%, 91.7% and 89.3%, NPV was 100% , 100% and 75.0%, and accuracy was 95.5% , 96.4% and 86.1%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of 64-slice spiral CT combined with exercise treadmill test in diagnosis of CAD were 97.6%, 97.7%, 97.6%, 97.7% and 97.7%, respectively. Conclusion 64-slice spiral CT combined with exercise treadmill test works well in screening CAD, especially for those with a low or intermediate estimated pretest probability.

Objective E0703 is derived from estradiol and has anti-radiation effects on irradiated mice, the effects of E0703 on cell viability,cell cycle and the related mechanism in irradiated AHH-1 cells were investigated in this study.Methods Cell viability,cell apoptosis and cell cycle were determined by Cell Counting Kit-8.Annexin V-FITC double staining kit and Flow Cytometry,respectively.Level of mRNA and protein were detected by RT-PCR and Western blot,respectively.Results 3.0 Gy 60 Co γ-rays induced significant cell cycle arrest,necrosis,apoptosis and reduction of viability.Pretreatment with E0703 for 12 h before irradiation could increase cell viability and regulate cell cycle.but had no obvious effect on cell necrosis and apoptosis.The expression of cell cycle arrest related molecules Rb and MDM2 were increased after 3.0 Gy irradiation,but decreased significantly with pretreatment of E0703.Moreover.the phosphorylation of Rb was also increased.Conclusions The radioprotective function of E0703 might be exerted through influencing on cell cycle and promoting cell proliferation instead of apoptosis or necrosis.
