MethodThe volume and location of focal lesion as well as the presence of cerebral atrophy in 44 MID patents with mild dementia, 40 MID patients withmoderate dementia, 38 MID patients with severe dementia were compared. Result The volume of focal lesion correlated with dementia degreeof MID. The bigger the volume was, the heavier the dementia was. The cerebral atropohy was heavier in patients with severe dementia than thatin patients with other dementia. Dementia degree of MID should no correlation with the location of focal lesion. Conclusion The volume andcerebral atrophy were important the factor for determing dementia degree of MID.

Purpose The aim of this study was to compare the pharmacokinetic(PK) profile and relative bioavailability of two sustained release tablets containing 10 mg mizolastine in healthy, young Chinese volunteers. Methods A single oral dose of mizolastine was given under fasting conditions to volunteers aged from 21 to 24 years in this open-label, randomized, crossover study. A ten-day washout period was applied between each of the two formulations. Plasma samples were obtained before dosing and at predetermined time points after dosing up to 48 hours and were analyzed for plasma concentration with a high-performance-liquid chromatography-UV method. PK parameters representing the extent and the rate of absorption of mizolastine were obtained. An analysis of variance, 90% confidence intervals, and two one-sided tests were employed for statistical analysis of relative difference between the two formulations. Results According to the pharmacokinetic and statistical analysis, parameters were not statistically different between the two formulations except the peak concentration (cmax). The point estimates of the ratios of AUC0→t, AUC0→∞ of mizolastine were (101.26 + 9.82) % and (102.52 + 8.61)% with 90% confidence intervals (CIs) of 95. 5% - 106. 5% and 97. 7% -106.9% respectively, comprised in the stipulated 80% - 125% range; for cmax values, the ratios was 82.17% - 15.32% with the 90% CIs of 71. 7% - 91.1%, fell in the recommended range of 70% -143%. Conclusions The results indicate that there is no statistically significant difference in PK parameters except cmax between the two sustained release tablets of mizolastine. The 90% CIs of AUC0→t,AUC0→∞ and cmax are within the predefined range. Thus, the two sustained release tablets of mizolastine are considered bioequivalent and generally well tolerated.

Objective To observe the efficacy and adverse reaction of the test drug hepatitis B immunoglobin on the post market.Method Employed by the methods of multiple center's clinical trials and using the recommended dosage of hepatitis B immunoglobulin for intravenous administration,the clinical efficacy of either prevention or treatment for hepatitis B recurrence and drug related adverse reactions were observed.This consisted of 22.1 months,13 hospitals,and 525 patients with hepatitis B related liver transplantation.Result The results showed a contrasting probability of adverse reactions for different doses among the observation period.Within 6 months postoperatively with a greater or equal to recommended drug dose,the infection rate was less than 4％.In contrast,the infection rate was greater than 12％ in the group with less than the recommended drug dose.Conclusion There was an obvious dose effect relationship,and the drug safety and recommended treatment rationality were verified.

ObjectiveTo assess revascularization and vessel anastomosis in digital replantations with DSA.MethodsTwelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis,hemodynamics,stenosis and discontinuation were investigated.The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers,the spasm and stenosis of the reattached vessels were considered as mild vascular crisis,and the discontinuation of hemodynamics were indicated as severe vascular crisis.ResultsThe total 27 vessels were clearly displayed on DSA.Of these vessels,23 vessels were unobstructed and smooth,all digits were survived.Diagnosis coincidence of early stage survival was 100%(23/23). Two vessels were obstructed,which were testified having thrombus by operation research.The other 2 vessels were spasm,the digits were also survived ultimately by expectant treatment.All 4 abnormal vessel anatomosis were found by DSA.Conclusion DSA is important modality in assessing revascularization and blood circulation for digital replantations,guiding in dealing with the vascular crisis,and in predicting early stage survival of the reattached digits.

Objective To screen the glycoproteins as biomarkers for intracranial aneurysm (ⅠA) in cerebrospinal fluid (CSF) and evaluate the specificity and sensitivity of the biomarker candidates.Methods A complementary proteomic approach integrated with multidimensional chromatography was employed to simultaneously measure relative changes in the gylcoproteins of cerebrospinal fluid (CSF) obtained from patients with ruptured ⅠA (RIA) and unruptured ⅠA (UIA) compared to the healthy controls (HC) and disease controls (DC).One protein-receptor tyrosine kinase Axl with a unique change in RIA was validated in CSF and plasma.The sensitivity at 95％ specificity of Axl in CSF and plasma was evaluated with receiver operating characteristic curve (ROC curve).Results Firstly,a total of 294 glycoproteins were identified in human CSF with believable evidence.Secondly,the proteomic findings showed the quantitative changes in RIA and UIA as compared to HC and DC.Of 294 identified CSF proteins,59,24 and 33 proteins displayed quantitative changes unique to RIA,UIA or IA,respectively.At last,one of these unique proteins-receptor tyrosine kinase Axl with unique increase in RIA was confirmed both in CSF and plasma.ROC curve analysis showed that the sensitivity at 95％ specificity of Axl in CSF to differentiate RIA from UIA was 60％.When compared to CSF,the sensitivity at above setting in plasma to differentiate RIA from HC was 40％ and to differentiate RIA from UIA was 25％.Conclusions A glycoprotein biomarker Axl might be used as a promising biomarker to predict the rupture of ⅠA.The further investigation of the relations between Axl and IA formation as well as rupture might help to elucidate the underlying pathogenesis and find new therapeutic targets.

Objective To evaluate the treatment effect and security of transcatheter arterial chemoembolization(TACE)combined with sorafinib for intermediate-advanced hepatocellular carcinoma.Methods From July 2008 to November 2010,the treatment effects of two groups of patients with advanced hepatocellular carcinoma were retrospectively analyzed and compared,including 44 patients treated by sorafenib combined with TACE(test group)and the other 44 patients treated only with TACE(control group).To assess the treatment effect based on mRECIST,the time for patients' tumor progression(TTP),overall survival(OS)time and adverse events were recorded.Survival rate were analyzed using KaplanMeier method and Log-rank analysis in SPSS 18.0.Results Till January 2011,24 patients(54.5％)survived and 20 patients(include patients lost to visit)died(45.5％)among the test group,13 patients survived(29.5 ％)and 31 patients(include patients lost to visit)died(70.5 ％)among the control group.No complete remission condition was observed in all patients.Among the test group,1 patient got partial remission,24 ones remain stable and 19 patients got progression.While among the control group,conditions remained stable in 21 patients and progressed in rest 23 ones.The disease control rate(DCR)in the test group and control group were 56.8％(25/44)and 47.7％(21/44)respectively,with no statistical significance(x2 =0.729,P =0.393).The median overall survival time(mOS)of test group and control group were 21.0(95 ％ CI:14.9-27.1)months and 10.0(95 ％ CI:6.4-13.6)months respectively,and the difference reached statistical significance(x2 =7.436,P =0.006).The median time to tumor progression(mTTP)of test group and control group was 1 1.0(95％ CI:8.7-13.3)and 6.0(95％ CI:3.9-8.1)months respectively,and the difference had statistical significance(x2 =10.437,P =0.001).The adverse events of test group mainly included hand-foot skin reaction,loss of appetite,fever,fatigue and diarrhea.The adverse events of control group mainly included fever,loss of appetite,nausea,vomiting and fatigue.The incidences of hand-foot skin reaction,baldness,diarrhea were significantly higher in test group than those in the control group(P ＜0.05).In most patients,these side effects were mild-to-moderate,and alleviated remarkablely after symptomatic treatment.Conclusions Compared with TACE alone,TACE combined with sorafenib can prolong the OS and TTP significantly for the patients with intermediate-advanced hepatocellular carcinoma.However,the DCR of the two groups has no statistical significance.
