Objective To discuss the optimal occasions for CsA withdrawal after kidney transplantation. Methods Thirty-eight cases of kidney transplantations in out-clinic were included in this study. CsA was withdrawn in their immunosuppressive regimen owing to different reasons after operation.All patients were followed up at least 2 years after operation, and followed up more than 12 months after CsA withdrawal. All patients were divided to two groups: Group A (18 cases), control group; group B (20cases), the CsA withdrawal owing its side effects. Acute rejection rate, SCr, uromicroprotein and side effects were analyzed in order to find the optimal occasions for CsA withdrawal Results CsA was re-administered in 9 cases (50 0/4) owing to different reasons in Group A. In group B, CsA was withdrawn due to gradually increased Scr and proteinuria in 12 cases, CsA related acute toxidty in 2 cases, hepatic injury in 8 cases and other reasons in 2 cases, After withdrawal of CsA, renal function was improved and hepatic injuries were recovered. Conclusion The suitable opportunity for CsA withdrawal for long-term survival patients should be at the beginning of gradually increased Scr and/or proteinuria. For the patients with normal and stable renal function and having no CsA related side effects, small dosage (1.5-2. 0 mg/kg)of CsA was the choice for the maintenance therapy.

Objective To investigate the changes of anticardiolipin antibody(ACA) and protein C(PC) in cirrhotic patients with or without portal vein thrombosis(PVT). Methods During Jan. 2006 to Dec. 2007, 60 cirrhotic patients with (n=20) or without (n=40) PVT were analyzed. The concentrations of prothrombin time (PT), activited patial thromboplastin time (APTT), fibrogen, ACA and protein C (PC) were determined. Results The positive rate of ACA was 35% (7/20) in PVT group and 10% (4/40) in control group (P=0.045). The average level of ACA-IgG was significantly higher in PVT group [(10.15±5.31)U/ml] than that in control group [(6.70±3.75) U/ml]. The concentration of PC was significantly lower in PVT group [(2.47±0.62) mg/L] than that in control group [(2.93±0.88)mg/L]. No difference was found in APTT, levels of fibrogen and ACA-IgM between two groups. PT and APTT were progressively prolonged and fibrogen and PC were decreasing with the severity of Child-Pugh, respectively. The levels of ACA-IgG and ACA-IgM were increasing with the severity of Child-Pugh. Conclusions The coagulation and anticoagulation system is abnormal in patients with PVT who has higer ACA-IgG level and lower PC level. It is indicated that the ACA and PC may play an important role in formation of PVT.

Endostatin is a novel anti-angiogenic drug which through multiple pathway inhibits vascular endothelial growth factor expression,to achieve the purpose of the inhibition of tumor angiogenesis.The drug in the treatment of non-small cell lung cancer in pre-clinical study and clinical application show that:used alone have anti-tumor effect; combined with radiotherapy and chemotherapy can obtain short-term curative effect,and does not increase treatment related toxicity.The adverse effect of the drug is mild and can be well tolerated.

Objective To explore MRI appearances of malignant mixed mesodermal tumors (MMMT) of the uterus. Methods All 9 patients with MMMT were proved by pathology. MRI characteristics of MMMTs in 9 patients were analyzed retrospectively.Results Of 9 MMMTs,6 were uterus body-based and 3 were cervical-based.Body-based MMMTs tended to be expansive or infiltrative growth with expanded uterus cavity. Cervical-based.MMMTs tended to be exophytic growth without myometrial infiltration. The tumors presented iso- or low signal on T1WI. The body-based MMMTs presented heterogeneously hyper-intense on T2WI ( n =5 ),hemorrhage ( n =1 ),cystic degeneration and necrosis (n =5) were seen within the tumors. Cervical-based MMMTs presented relative hyper-intense signal on T2WI with band or tree-like hypo-intense signal,without hemorrhage and necrosis. Body-based MMMTs were enhanced more obviously than cervical-based MMMTs.Conclusions The growth pattern,MRI signal and enhancement characteristics of cervix and uterus body MMMTs are different. MRI is helpful for the diagnosis of MMMT.

Objective To investigate the relationship between thrombomodulin(TM), fibrinolytic system changes and the score of the model for end-stage liver disease(MELD)in liver cirrhosis patients.Methods Eighty-five liver cirrhosis patients admitted from January 2008 to December 2009 were included in this study. TM, D-dimer, tissue plasminogen activator(t-PA), plasminogen activator inhibitor -1(PAI-1),serum creatinine, serum total bilirubin and international normalized ratio(INR)on all patients were measured and then the score of the MELD was calculated. Results The score of the MELD was 1-29(11.35 ± 6.02)scores. The score of the MELD ≤ 9 scores was 40 cases(47.1%), 10- 19 scores was 32 cases (37.6%),20-29 scores was 13 cases(15.3%).TM and D-dimer were progressively increased with MELD score. There was significant difference among the three groups(P＜0.01). The levels of TM and D-dimer had positive correlation with the score of the MELD(r = 0.706,0.425,P ＜ 0.01). Conclusions The levels of TM and D-dimer have positive correlation with the score of the MELD in liver cirrhosis patients. These indices can help predicting the degree of liver function disorder and prognosis.

Objective To observe the effects of Panax notoginseng saponins and aspirin on platelet aggregation and analyzed resistance probability.Methods One hundred and twenty patients with cerebral infarction were di-vided randomly into Panax notoginseng saponins group and the aspirin group (each group 30 cases),respectively treated with adenosine diphosphatc (ADP),arachidonic acid (AA) to induced and detect the largest platelet aggre-gation (MAR).All patients received platelet aggregation test in hospital on the first and 14th day.Results In Pa-nax notoginseng saponins group and the aspirin group platelet aggregation induced by gents in the same role did not show statistical significance.There were resistances,semi-resistance phenomenon.Conclusions Panax notogin-seng saponins on platelet aggregation and the impact of aspirin was not significant; it may be used as anti-platelet aggregation drug,but there is also the resistance phenomenon.By combining Panax notoginseng saponins other an-ti-platelet drug anti-platelet aggregation of the long-term clinical.It might solve the resistance problem through large-scale clinical trials.

Objective To investigate the relationship of thyroid hormone (TH), thyroid stimulating hormone (TSH) and blood calcium in hyperlipidemic acute pancreatitis (HLAP) patients. Methods Fifty patients with HLAP were selected, among whom 37 patients with mild acute pancreatitis (MAP) were enrolled into MAP group, and 13 patients with moderately severe acute pancreatitis (MSAP) were enrolled into MSAP group. The albumin, blood glucose, creatinine, blood lipids, blood calcium, free tri-iodothyronine (FT3), free thyroxine (FT4) and TSH levels were measured and analyzed. Results The blood calcium, FT3 and TSH levels in MAP group were significantly higher than those in MSAP group:(2.02 ± 0.26) mmol/L vs. (1.75 ± 0.27) mmol/L, (1.88 ± 0.46) ng/L vs. (1.52 ± 0.35) ng/L and (0.28 ± 0.20) mU/L vs. (0.17 ± 0.12) mU/L, but the blood glucose and triglycerides (TG) levels were significantly lower than those in MSAP group: (13.36 ± 5.83) mmol/L vs. (19.99 ± 7.97) mmol/L and (24.01±12.46) mmol/L vs. (34.76 ± 20.39) mmol/L, and there were statistical differences (P<0.01 or<0.05). There were no statistical differences in albumin, creatinine, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol (LDL-C) and FT4 levels between 2 groups (P>0.05). The correlation analysis result showed: in patients with HLAP, TSH and albumin had a positive correlation with blood calcium (r=0.344 and 0.372, P=0.014 and 0.008), LDL-C and TG had negative correlation with blood calcium (r=-0.315 and-0.444, P=0.026 and 0.001), and other indexes had no correlation with blood calcium (P>0.05). Conclusions Blood calcium, FT3 and TSH levels are decreased with severity of HLAP. Decreased blood calcium may be one of reasons for decreased TSH in HLAP patients.
