The increased level of fibrinogen (Fg) is an independent factor that resulting in the occurrence of ischemic cardio-cerebrovascular diseases. The Fg level is correlated with heredity, age, sex, obesity, lipid, smoke, inflammation and infection, and the pathogenic effect of genetic factor has been increasingly receiving attention. In recent years, more than 10 FgBβ gene polymorphisms have been reported, among them, - 148C/T, - 455G/A, and - 854G/A are considered to be significantly correlated with the increased level of Fg, and may be one of the most key factors in influencing the genetic risk factors of the occurrence of ischemic cerebrovascular disease.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy associated with poor prognosis.Increasing data regarding to alteration of gene expression signatures of oncogenes and tumor suppressors involved in the pathogenesis of T-ALL and the major mechanisms of T-cell transformation may contribute to define the biological markers for treatment response and prognosis,and has important clinical implications.In this review,advance knowledge concerning the characteristics of early T-cell precursor ALL,the alteration of TAL1 and NOTCH1 related genes and target inhibiton effects based on these alterations from 2012 the 54th ASH annual meeting ars summarized.

ObjectiveTo systematically review the curative effect and safety of compound realgar and natural indigo tablet (CRNIT) therapy in acute promyelocytic leukemia (APL). MethodsThe clinical data of randomized trials on SinoMed, CNKI, VIP,WANFANG DATA,CBA, PubMed, MEDLINE, EMBASE, the Cochrane Library were searched by internet,in addition to manual retrieval and collecting all published literatures randomized controlled trials (RCT) about CRNIT therapy in APL home and abroad.Retrieval line was up to March 2011. According to the inclusion criteria and exclusion criteria, screening all literatures and evaluating their qualities. The rate of complete remission (CR), time to CR, recurrence rate, mortality, rate of adverse reaction and so on were used as evaluation indicators for meta-analysis by RevMan 5.1.Results Data from six RCTs involving 391 APL patients,including 2 RCTs about comparison of CRNIT and Arsenic Trioxide (ATO), 4 RCTs about comparison of CRNIT and all-trans retinoic acid (ATRA) (including adding 1 RCT about comparison of CRNIT + ATRA and ATRA). Time to CR: CRNIT was longer than ATRA and ATO (WMD = 3.14, 95 ％ CI 0.99-5.29, P= 0.004). Headache incidence: CRNIT was lower than ATRA (OR = 0.10, 95 ％ CI 0.02-0.45, P = 0.003). 5-year disease-free survival rate: CRNIT was better than ATRA (OR = 7.22, 95 ％ CI 1.40-37.25, P = 0.02). There were no statistical significance in the rest of the Meta-analysis results.ConclusionThe time to CR of CRNIT is longer than that of ATRA and ATO.The short-term effect of CRNIT is similar to that of ATRA and ATO.The 5-year disease-free survival rate of CRNIRT may be higher than that of ATRA.

Objective To observe the blood supply of the extra hepatic duct and prevent the ischemia of extra hepatic duct after liver transplantation. Methods Microdissection for the main arteries of extra hepatic duct in 15 samples was performed. Results The main arteries supplying extra hepatic duct included cystic artery’s branches and posterior superior pancreaticoduodenal artery’s branches. There were 1~3 cystic artery’s branches and 3~5 posterior superior pancreaticoduodenal artery’s branches to supply extra hepatic duct. Conclusion The posterior superior pancreaticoduodenal artery is one of the main arteries supplying extra hepatic duct. In orthotopic liver transplantation, this artery is considered to preserve.

Objective To evaluate the therapeutic effect of autologous hematopoietic stem cell transplantation(AHSCT)on hematological malignancies and solid tumors.Methods Twenty patients with age from 18 to 50 years received AHSCT.Two or 3 of following agents,Cytarabine(Ara-C)3～4 g/m2,Cyclophosphamide(CTX)4～6 g/m2,Etoposide(VP-16)0.5～1.0 g/m2,Semustine(me-CCNU)300 mg/m2,Melphalan(Mel)140 mg/m2,Thiotep a(TSPA)600 mg/m2,Carboplatin(CBP)1.0 g/m2,Busulfan 16mg/kg,were combined as conditioning regimen in all patients.Among them 2 patients with ALL accepted additional total body irradiation(TBI).Results All the patients have reconstituted bone marrow hematopoiesis after transplantation.None of them had the transplantation-related mortality.Among 20 patients with CML and malignant lymphoma,15 achieved disease-free survival(DFS)with a median survival time of 39.5(2～109)months.Conclusion AHSCT might represent an effective approach to the treatment of some patients with chemosensitive solid tumor who are complete remission or part remission.It is suggested that the patients have got a obvious survival benefit from AHSCT.

Gastrointestinal benign stricture is a common disease with symptoms of dysphagia,abdominal pain and difficult defecation,which severely impair the quality of life for patients.Endoscopic intervention is the first-line treatment,and the available methods include balloon dilation,local drug injection and stent insertion,etc.Endoscopic incision was first used for the treatment of Schatzki's rings,and later it was used for the treatment of other gastrointestinal benign strictures,and the promising results were achieved.

Objective To investigate the impact of auto and allogenic mesenchymal stem cells (MSC) transplantation on hematopoietic reconstitution. Methods MSC from auto, donor bone marrow or embryonic tissue were cultured and expanded in vitro in the serum culture system. Five patients received hematopoietic stem cell transplantation (HSCT) were investigated. Case 1 of systemic lupus erythematosus and Case 2 of non-hodgkin' s lymphoma (NHL) received auto MSC transplant before auto-HSCT. Case 3 of paroxysmal nocturnal hemoglobinuria received HLA-identical allogenic MSC transplant before HLA-identical allo-HSCT.Case 4 of chronic myelocytic leukemia and Case 5 of NHL had delayed hematopoietic reconstitution (129th and 78th day, respectively) after allo- and auto-HSCT, respectively, and received MSC from embryonic tissue.Results Case 1, 2 and 3 had no manifested side effects after MSC transplantation combined with HSCT.Neutrophil count of case 1, 2, and 3 were over 0.5 ×109/L at 1st, 10th and 10th day, respectively, platelet count were over 20 ×109/L at 1st, 8th and 33th day, respectively, and agranulocytosis at Ost, 7th and 12th day, respectively. The treatment of embryonic tissue MSC transplant was confirmed to fail for Case 4 and 5.Conclusion The time of MSC transplant has a great impact on hematopoietic reconstitution. MSC transplantation and HSCT performed simultaneously can improve hematopoietic reconstitution. However, the impact of MSC on patients with delayed hematopoietic reconstitution after HSCT needs further study.

Objective:This study aims to examine the clinicopathological features, diagnosis, and treatment of pulmonary margin-al zone B-cell lymphoma of mucosa-associated lymphoid tissue (PMZL-MALT). Methods:The clinicopathological features and immu-nohistochemical staining of CD20, CD79a, CD5, CD10, CD23, CyclinD1, and Ki-67 in seven patients with PMZL-MALT were ana-lyzed. Results:These patients, with a median age of 58 years, included three males and four females. Most of the patients suffered from cough, anhelation, and irregular fever. No specific imaging manifestation was observed. Tumor cells were positive for CD19 and CD20 but negative for CD5, CD10, and CyclinD1. The positive rate of Ki-67 was low. Conclusion:PMZL-MALT cases are easily misdiag-nosed because of the absence of specific clinical characteristics and X-ray features. Final diagnosis depends on pathological examina-tions.
