Biliary atresia (BA) is one of the most serious pediatric surgical digestive system diseases with progressive liv?er bile duct inflammation and fibrous obstruction. Currently, the etiology of BA is not clear. It may be associated with genetic predisposition, viral infections and immune injury. Now many scholars believe that it was resulted from multiple factors. Among them, the theory of immune-inflammatory is supported by most scholars. Now the mechanisms of CD38, CD138 and IgG4 in autoimmune liver disease were reported in literature. BA and other autoimmune liver diseases are similar in terms that both inflammatory and immune responses plays irreplaceable role during disease development. Therefore, this article briefly review the role of CD38, CD138 and IgG4 in the inflammation-immunity of BA.

Silent mating type information regulation 2 homolog-1 ( SIRT1 ) is a nicotinamide adenine dinucleotide ( NAD)-dependent deacetylase, which can deacetylate histone and non-histone proteins and is involved in many life proces-ses, such as energy metabolism, cell senescence and apoptosis.SIRT1 can enhance the cellular energy supply, inhibit cell apoptosis, alleviate inflammation, enhance the resistance of oxidative stress and improve the function of endothelial cells by deacetylating relevant factors in many vascular-related diseases.This article summarizes the current research progress in the function and signal pathway of SIRT1 in ischemic stroke, atherosclerosis and tumors.

Objective To observe the characteristics of culprit lesions in AMI with previous PCI.Methods Retrospective analysis was carried out in 61 consecutive AMI patients with previous PCI treated with primary PCI from April, 2004 to April, 2006 in Fuwai hospital.Results Location of culprit lesions in the 61 patients (62.1?10.0 yrs; male 88.5%) were: LAD 47.5%, RCA 39.5%, LCX 13.0%. Comparing the medication of the patients during the first year after the former PCI, besides the continous use of aspirin (93.8% vs 100%,P=0.113), all patients had stopped using clopidogrel, and the use of ?-blockers, ACEIs and statins also dropped significantly after 1 year (46.9% vs 75.0%, P= 0.001; 34.4% vs 70.8%, P= 0.001; and 28.1% vs 77.1%, P= 0.000, respectively). The characteristics of the culprit lesions included: acute and sub-acute in-stent thrombosis in 12 cases (19.7%), late and very late in-stent thrombosis in 6 cases (9.8%), plaque rapture in 41 cases (70.5%), but no restenosis was involved. The time of the recurrant AMI after the former PCI were: 13 cases (21.3%) within 1 month including 12 cases of acute or subacute in-stent thrombosis and 1 case of plaque rupture in anther coronary artery 3 days after primary PCI; 16 cases (26.2%) after the first month to 1 year including 12 cases of plaque rupture and 4 cases of late in-stent thrombosis; 32 cases (52.5%) 1 year including 30 cases of plaque rupture and 2 cases of very late in-stent thrombosis. Conclusion The major mechanism of recurrant AMI after preoious PCI is plaque rapture.

Objective To detect Snail and Raf kinase inhibitor protein (RKIP) expressions in NSCLC (Non-Small Cell Lung Cancer) and their relationship with the pathological characteristics of tumor. Methods Immunohistochemistry was used to detect Snail and RKIP expression in 124 NSCLC samples and 67 paraneoplastic normal lung tissue samples. Snail and RKIP positive expression rates were compared upon clinicopathologic characteristics. Correlation of Snail expres-sion with RKIP expression was also analyzed. Results Positive expression rate of Snail was 79.03%in lung cancer, which is higher than that in normal lung tissue 19.40%(χ2=63.538, P＜0.01);positive expression rate of RKIP was 36.29%in lung cancer which is lower than that in normal lung tissue 77.61%(χ2=29.716,P＜0.01), Snail and RKIP expressions are corre-lated with tumor differentiation, TNM stage, lymph node metastasis and postoperative survival time ( P＜0.05, respectively) . Snail protein expression is negatively correlated with RKIP expression in NSCLC (P＜0.05). Conclusion High Snail ex-pression and the low RKIP expression might be important biological markers for invasion and metastasis of NSCLC, which might be used as important prognostic indicators in NSCLC.

Objective:To observe the difference of the therapeutic effect between heat-sensitive moxibustion and warm needling therapy for cervical spondylosis of vertebral artery type (CSA).
Methods:A total of 60 cases with CSA who met the inclusion criteria were randomly divided into a heat-sensitive moxibustion (HSM) group and a warm needling therapy (WNT) group according to the visiting sequences, with 30 cases in each group. Patients in the former group were treated by heat-sensitive moxibustion, while patients in the latter group were treated by warm needling therapy. Both groups were treated once every other day, with 10 times as 1 course of treatment, and the therapeutic effects were evaluated after 1 course of treatment.
Results:After 1 course of treatment, the total effective rate of the HSM group was 93.3%, versus 83.3% in the WNT group. There was a statistically significant difference between the two groups (P<0.05).
Conclusion:Heat-sensitive moxibustion has better therapeutic effect for CSA than warm needling therapy.

Objective To summarize clinical characteristics of coronary artery perforation during percutaneous coronary interventions.Methods Retrospective analysis of consecutive 32 patients who had coronary artery perforation in Fu Wai Hospital from April,2004 to August,2006 was carried out.Results Thirty-two cases of coronary perforation occurred during 7102 PCI procedures performed within this period(incidence:0.5%).These cases are comparatively complicated lesions including 81.3% of type B2+C and 62.5% of chronic total occlusion(CTO)lesions.Ellis classification:typeⅠ:14(43.8%),type Ⅱ:10(31.2%),type Ⅲ:8(25.0%),type Ⅳ:0.Mechanism of coronary artery perforation:guiding wire:21(65.6%),predilatation:6(18.8%),postdilatation:3(9.4%),stent implantation:2(6.2%).Clinical consequence:death:3(9.4%),cardiac temponade:7(21.9%),acute myocardial infarction(AMI):9(28.1%).Treatment:reversal of heparin-induced anticoagulation by application of protamine:14(43.8%),prolonged balloon inflation:9(28.1%),percardiocentesis:7(21.9%),implantation of membrane covered stent:4(12.5%),bail-out surgical repair:2(6.2%).Conclusion Coronary perforation during PCI is a rare complication;type Ⅲ perforation is associated with significant morbidity and mortality,which needs urgent and intensive treatment.

Objective To discuss the effect of psychological intervention combined with aspirin on the quality of life in patients with acute myocardial infarction (AMI) and surgical treatment of acute myocardial infarction (AMI).Methods 78 patients with acute myocardial infarction undergoing operation in our hospital from January 2015 to June 2016 were randomly divided into experimental group and control group,39 cases in each groups.The control group was treated with clopidogrel and aspirin.The experimental group was treated with aspirin and aspirin and psychological intervention.The therapeutic effects of the two groups were compared and analyzed.Results The experimental group ECGST recovery rate was 82.05%, the pain relief rate was 94.87%, chest X-ray improvement rate was 71.79%, the control group of ECGST segment recovery rate was 61.53%, the pain relief rate was 71.79%, chest X-ray improvement rate was 48.71%, the recovery rate of clinical symptoms of the experimental group was significantly higher than the control group, with statistical significance the difference between the two groups (P<0.05);the quality of life of the experimental group was significantly better than the control group, with significant difference between two groups (P<0.05), experimental group after treatment, mean platelet volume and platelet count before treatment was significantly better than before treatment, the difference was statistically significant(P<0.05).Conclusion In patients with myocardial infarction treated with aspirin and ticagrelor and psychological nursing, found that patients with symptoms change obviously, and the quality of life has improved, is conducive to the recovery of patients, worthy of clinical popularization and application.
