Objective To compare the patency rate of percutaneous balloon angioplasty or stenting for restenosis of femoral-popliteal artery artificial vascular grafting.Method 78 cases of femoral-popliteal artery artificial vascular graft postoperative occlusion patients were divided into 2 groups:anastomotic balloon angioplasty group (36 cases) and stent angioplasty group (42 cases) after double-lumen catheter embolectomy.Patients in anastomotic balloon dilatation group were given balloon angioplasty only becaus fine narrow flow signals were seen in angiography.Patients in stenting group received balloon angioplasty followed by suitable caliber self-expanding stent placement.Patency rates were compared between the two groups after 12,36 months of interventional treatment.Results The patency rate in stenting group was higher than that of percutaneous balloon angioplasty group (x2 =7.422,P ＜ 0.05).Conclusions Balloon stenting angioplasty had advantages of high patency rate over balloon dilatation for the treatment of postoperative occlusion of femoral-popliteal artery grafting.

Objective To investigate the effect of injecting?-acceptor inhibitor on the acute extensive miocardial infarction prognosis. Methods 53 cases patients with acute extensive miocardial infarction were injected Betaloc 5mg, after 3 times, taken Betaloc orally. Betaloc was not applied in another 49 cases patients with acute extensive miocardial infarction.The curative effect was compared between the two groups. Results The efficient or inefficient ratio of the group with Betaloc or the group without Betaloc was 48/53, 5/53 or 36/49, 13/49 respectively. The difference was significant by ?~2 test .Conclusions The patient with acute extensive miocardial infarction can get the extra good by means of early application of ?-acceptor inhibitor except the patient with no-no of the application of Betaloc.

Objective To study the possible pathogenesis of TNBS (2,4,6-trinitrobenzenesulfonic acid)-induced inflammatory bowel disease (IBD) in a mouse model by analyzing histological changes in colon and the expression of cytokines and transcription factor RORγt related to T cell subsets in mesenteric lymph nodes.Methods Female BALB/c mice aged 6-8 weeks were randomly grouped into two groups: IBD model and normal control groups.The mouse model of IBD was established by treating mice with 200 μl of 5％ TNBS/50％ ethanol solution (1∶1) through intestinal instillation, while the mice in the normal control group were instilled with PBS.Pathological changes in colon samples of mice were observed.Real-time PCR was performed to detect the dynamic expression of Th1 cytokines (IL-2, IFN-γ and IL-12p40), Th2 cytokine (IL-4), Treg-related cytokine (IL-10), Th17 cell-related cytokines (IL-17, IL-21 and IL-23) and transcription factor RORγt in mesenteric lymph nodes.Results The mice in the model group begun to show abnormal vital signs such as diarrhea, loss of weight and reduced activity, and mild hyperemia of intestinal mucosa and edema from the third day after modeling.Slight lesions were observed in histological slices of colon tissues stained with hematoxylin and eosin (HE).The expression of IL-21, IL-23 and IL-17 at mRNA level were significantly increased, while the expression of other cytokines showed no significant change.On the sixth day after modeling, many pathological symptoms and intestinal mucosal lesions were aggravated, and marked infiltration of inflammatory cells was observed in histological slices of colon tissues, which indicated that the IBD model was successfully induced by TNBS.Compared with the control group, the IBD model group showed significantly enhanced expression of IL-2, IL-12p40 and IL-10 in mesenteric lymph nodes at mRNA level on the sixth day after modeling.Although the expression of IL-21, IL-23, IL-17 and RORγt at mRNA level on the sixth day were down-regulated to different extent as compared with those on the third day, they were still significantly higher than those of the control group.Conclusion Th17 cell-related cytokines play an important role in the early stage of TNBS-induced IBD.With the progression of the disease, both Th1 and Th17 cells are involved in the immunopathological injury of colon tissues.

Objective To evaluate short and medium term therapeutic effects of VIABAHN-covered stent in treat-ment of arteriosclerosis obliterans in lower extremity. Methods Among all 53 cases of arteriosclerosis obliterans in lower extremity with C/D TASC levels, 22 patients underwent VIABAHN-covered stent (stent group), while the other 31 patients were treated with femoral-popliteal artery bypass grafting surgery (graft group). The arterial patency rates were analyzed 3 and 6 months after the two different surgeries. Results The number of arterial patency cases were 28 (90.3%) at 3 months and 26 (83.9%) at 6 months in stent group while it is 22 (100%) at 3 months and 21 (95.5%) at 6 months in graft group. There were no significant differences in the arterial patency rate at 3 months and 6 months between the two different surger-ies (χ2 is 0.808 and 0.760 respectively, P>0.05). Conclusion VIABAHN-covered stent can be used as the preferred treat-ment for arteriosclerosis obliterans of lower extremity.

Objective To investigate the dynamic changes and influencing factors of peripheral blood white blood cells (WBC), differential counts (DCs) and platelet (PLT) count in preterm infants to understand the changing characteristics of these blood parameters in preterm infants of different postnatal age, gestational age, and birth weight.Methods Totally 2 849 preterm infants admitted to the Department of Neonatology of Northwest Women's and Children's Hospital from November 30, 2011 to November 30, 2014 were retrospectively analyzed except for those diagnosed with infectious diseases, hematological system diseases, or immunologic diseases.All of the subjects were divided into seven groups based on their postnatal age, three groups based on gestational age and three groups based on birth weight, or male and female groups, respectively.Peripheral blood samples were obtained for determination of WBC, DCs and PLT.Statistical analysis was performed with oneway analysis of variance, t-test and Spearman linear correlation analysis.Results WBC, neutrophil (Ne), lymphocyte (Ly), monocyte (Mo), eosinophil (Eo), basophil (Ba) and PLT counts were significantly different among the seven groups of preterm babies of different postnatal age (F=172.00, 364.90, 34.88, 14.22, 80.82, 168.10 and 86.64, respectively, all P ＜ 0.01).WBC was found to be at the peak value within one day after birth [(18.40±6.87)× 109/L], followed by remarkable decrease in day ＞ 2-≤ 5 [(10.62±4.68)× 109/L], further gradual decrease thereafter, and then being stable in day ＞ 14-≤ 21 and ＞ 21 ≤≤ 30 [(10.54±3.09)× 109/L and (10.27 ± 3.70) × 109/L, respectively].PLT counts showed no significant change within one day after birth and in day ＞ 1-≤ 2 [(240.56± 63.54)× 109/L and (240.85 ± 71.47) × 109/L, respectively], then began to increase in day ＞ 2-≤ 5 [(249.21 ±80.55)× 109/L], peaked in day ＞ 7-≤ 14 [(339.11 ± 121.84)× 109/L], and decreased gently and became stable finally.The changing trends of Ne and Ly were cross and inverted in day ＞ 5-≤ 7.WBC, Ne, Ly, Mo, Eo, Ba and PLT counts of the preterm infants were all correlated with the postnatal age shown by Spearman linear correlation analysis (r=-0.46,-0.60, 0.18,-0.07, 0.33,-0.47 and 0.29, respectively, all P ＜ 0.01).With the increase of gestational age, WBC, Ne, Mo, and PLT counts increased, but Ly and Eo counts decreased.And all of the above showed significant difference (F=81.00, 124.49, 13.34, 18.35, 5.35 and 4.11, respectively, all P ＜ 0.05).While, the WBC, Ne, Mo, Ba and PLT counts showed positive relationship with the increase of birth weight (F=122.12, 133.09, 39.38, 13.77 and 21.24, respectively, all P ＜ 0.05).WBC, Ne and PLT counts of female infants were higher than those of male babies (t=l 6.35, 16.72 and 13.19, respectively, all P ＜ 0.05).Conclusions The peripheral WBC, DCs and PLT counts of preterm infants change dynamically with postnatal age with the remarkable variations on day ＞2-≤ 5 after birth and stable after 14 days of age.WBC, DCs and PLT counts might all be influenced by gestational age, birth weight and gender to some cxtend.

Objective: To investigate the mechanism of Glytan lowering portal pressure induced by biliary liver fibrosis. Methods: SD male rats, 240-260g weight around, were randomly divided into sham-operation group, model group, propranolol group, Glytan high-dose, middle-dose and low-dose group according to the weight. Portal hypertension was induced by common bile duct ligation in rats. After two and four weeks, measured the portal pressure(PP) of each group, observed the histological changes of liver by HE staining, tested liver function and the concentration of endothelin-1 in systemic circulation and mesenteric circulation radioimmnuoassay. Results: After two and four weeks, portal pressure of model group rats increased significantly. Both Glytan and propranolol can decrease PP after two and four weeks, and the pressure-relief effect was similar between the two drugs. HE staining showed that Glytan can significantly inhibit the formation of collagen, promote the recovery of liver tissue structure; liver function indicated a significant decrease in serum AST, ALT, TBIL and Na+ concentration. In addition, Glytan decreased the concentration of endothelin -1 in systemic circulation, increased it in mesenteric circulation after two weeks. Conclusion: Glytan decrease PP by improving liver function and microcirculation, inhibiting collagen formation and water-sodium retention after long-term therapy, ameliorating hyperdynamic circulation at the early stage.

Objective To determine the effects of hypoxia inducible factor-1α(HIF-1α) expression on postoperative adjuvant radiotherapy in esophageal carcinoma. Methods 95 cases with esophageal carcinoms who received radical operation were analyzed with followed-up data from 1995 to 1998.Expression of HIF-1α in 45 patients with esophageal carcinoma who received radiotherapy after radical operation were deternlined by immunohistochemical method in contrast with 50 patients with esophageal carcinoma received surgery alone.Kaplan-Meier method and COX proportional hazard model were used to analyze.Results The positive expression of HIF-1α in esophageal carcinoma was observed mainly in the nucleus of tumor cells.The positive expression rate of HIF-1α in esophageal carcinoma was 58.9%.The expression of HIF-1α had no relationship with age,sex,histologic subtype and T stage,but had positive relationship with recurrence and distant metastasis.There was significant difference between patients with positive and negative HIF-1α protein expression in surgery alone and postoperation radiotherapy group. COX model analysis showed that HIF-1α had separate and significant impacts on prognosis in surgery group and surgery plus radiotherapy group. Conclusion Over expression of HIF-1α protein suggests a poor prognosis,and has tendency to resist radiotherapy in esophageal carcinoma.

Objective To investigate cerebral hemodynamic changes in patients with unilateral stenosis of carotid artery by using CTP and CTA,and to analyze the dependability of the degree of artery stenosis and cerebral hemodynamic changes.Methods Fifty patients with unilateral stenosis of carotid artery underwent toshiba aquilion one CTP and CTA.The patients were divided into mod-erate stenosis group,severe stenosis group and occlusion group according to the NASCET criteria.The rCBF,rCBV,rMTT and rTTP were measured ,and compared between stenosis and contralateral hemispheres ,and the dependability were analyzed between the de-gree of unilateral carotid artery stenosis and relative perfusion parameters by using ranking-test.Results (1)There were 20 cases of unilateral carotid artery occlusion,13 severe stenosis,1 7 moderate stenosis.(2 )No statistical significance on rCBF and rCBV was found among the three stenotic groups (P>0.05).There were statistical significances on rMTT and rTTP among the three stenotic groups(P<0.05).(3)There were statistically no correlations between the values of rCBV,rCBF and the degree of artery stenosis.There were statistically positive correlations between the values of rMTT,rTTP and the degree of artery stenosis with the pearson correlations 0.512 and 0.708. Conclusion rMTT and rTTP are more sensitive parameters for evaluation of cerebral hemodynamics and dependability of carotid ar-tery stenosis on the CTP and CTA.These have an important value to guide the clinical treatment.
