Objective To investigate the value of combined 3D-constructive interference in steady state(3D-CISS) with phase-contrast MR(PC-MR) in diagnosis of hydrocephalus children.Methods We collected retrospectively 28 children with hydrocephalus who caused by obstructive membranes.They all underwent MR imaging examination with a 1.5 T consisting of 3D-CISS, conventional sequences and PC-MR.With the result of surgery and CT cisternography as gold standard,we analysised different sequence in the diagnosis of membranous obstruction.The results of obstructive were analysed by x2 test between 3D-CISS combined with PC-MR and conventional sequences.Results The study included 28 children, of whom 16 showed obstructive membranes in CSF pathways of ventricle and 12 displayed obstructive membranes in CSF pathways of cistern.Conventional sequences diagnosed obstructive membranes of 15 children, and obstructive membranes of 11 children were consistent with gold standard, and 4 cases were false positive.The 3D-CISS diagnosed obstructive membranes of 40, and 12 cases were false positive.There were significant difference between 3D-CISS combined with PC-MR and conventional sequence about obstructive membranes diagnosis of CSF pathways(x2=24.410, P=0.001).Conclusions Making use of jointing 3D-CISS sequence and PC-MR sequence successively, and we can diagnose the position of obstructive membrane for hydrocephalus, which can be helpful to select a perfect surgical approach.

The aim of this study was to evaluate the therapeutic effects and adverse reactions of fludarabine-based regimen for patients with chronic lymphocytic leukemia(CLL).18 patients with CLL were treated with F regimen [fludarabine 30 mg/(m(2)·d) intravenously for 3 d, repeatedly every 28 days]. 22 patients were treated with FC regimen [fludarabine 25 mg/(m(2)·d) plus cyclophosphamide 250 mg/(m(2)·d) intravenously for 3 d, repeatedly every 28 days]. The results showed that the rate of complete remission (CR), partial remission (PR) and overall remission (OR) reached 16.7%, 61.1% and 77.8% in the F regimen groups and 59.1%, 40.9% and 100% in the FC regimen groups (P < 0.05, P > 0.05 and P > 0.05), respectively. FC regimen resulted in significantly higher CR rate than that in single-agent fludarabine regimen. The main adverse reactions were myelosuppression and immunosuppression. No significant differences were found between the two regimens. FC regimen did not increase the rate of severe infections. It is concluded that FC regimen can give higher CR rate as compared with F regimen, fludarabine-based regimens is effective and safe first-line regimen for patients with CLL.

This study was purposed to investigate the dynamically monitoring minimal residual disease (MRD) by flow cytometry (FCM) in patients with acute leukemia (AL) after complete remission and its relation with prognosis. From October 2010 to May 2012, 58 cases of AL (including 45 cases of AML and 13 cases of ALL) were regularly monitored for MRD in bone marrow by FCM and their bone marrow morphology was observed by light microscopy at the same time which continued to relapse or to follow-up deadline in the Department of Hematology, the First Affiliated Hospital of Zhengzhou University. Through average follow-up for 9 months (3 - 21 months), the average MRD level of patients with CR was got. And the prognostic value of MRD level at different time points in AL patients after CR was analysed and summarized. MRD ≥ 1% was defined as positive, otherwise, as negative. The results showed that the maximum and minimum MRD levels of 45 AML patients were 9.57% and 0.01% respectively, the average was 0.67%; the maximum and minimum MRD levels of 13 cases of ALL patients were 7.9% and 0.0016% respectively, the average was 0.99%. Among 44 cases after induction therapy, the relapse rate of MRD(+) group was 53.3% (8/15), the relapse rate of MRD(-) group was 10.3% (3/29), and the relapse rate of MRD(+) group was higher than that of MRD(-) group (χ(2) = 7.58, P = 0.006). Among 58 cases after the first consolidatory therapy, the relapse rate of MRD(+) group was 62.5% (5/8), the relapse rate of MRD(-) group was 16.0% (8/50), and the relapse rate of MRD(+) group was higher than that of MRD(-) group (χ(2) = 6.11, P = 0.013). It is concluded that MRD detected by FCM has a large range (10(-6) - 10(-2)), which can not be used as a single indicator of complete remission. When MRD ≥ 1% after induction therapy and the first consolidatory therapy, the relapse rate significantly increases, MRD can be used as a sensitive indicator for prognosis.

This study was purposed to explore the correlation of chromosome karyotype with dyshaematopoiesis and reticulin in myelodysplastic syndrome (MDS). The data of 202 MDS patients diagnosed and treated in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed in term of chromosome karyotype, dyshaematopoiesis and reticulin detection results. The chromosome karyotypes were categorized according to the International Prognostic Scoring System (IPSS). The results showed that there was a positive correlation between chromosome karyotype grading and number of lineages with dyshaematopoiesis (r = 0.443, P < 0.05). The detected rates of multilineage dyshaematopoiesis in patients with good, intermediate and poor chromosome karyotypes were 44.4%, 71.4% and 96.3% respectively. There was a positive correlation between chromosome karyotype grading and reticulin grading (r = 0.451, P < 0.05). The positive rates of reticulin in patients with good grading, intermediate and poor chromosome karyotypes were 36.8%, 64.3% and 92.6% respectively. The detected rate of multilineage dyshaematopoiesis, number of lineages with dyshaematopoiesis, the positive rate of reticulin and reticulin grade in patients with poor karyotypes were higher than those in patients with intermediate or good chromosome karyotypes (separately P < 0.01). The above data in patients with intermediate chromosome karyotypes were higher than those in patients with good chromosome karyotypes (separately P < 0.01). It is concluded that the chromosome karyotype grading positively correlates with the number of lineages with dyshaematopoiesis and reticulin grading. When the chromosome karyotype changed from good to poor, the detected rate of multilineage dyshaematopoiesis, number of lineages with dyshaematopoiesis, positive rate of reticulin and reticulin grading became higher and higher.

OBJECTIVETo evaluate the efficacy and safety of Tolterodine Tartrate combined with the alpha-receptor blocker in the treatment of benign prostatic hyperplasia with detrusor overactivity (BPH-DO).

METHODSA total of 113 patients with BPH-DO were randomly assigned to receive Tolterodine Tartrate combined with Cardura (Group A) and Cardura alone (Group B), both for 12 weeks. Then we recorded and compared their average 24 h urinary frequency, IPSS and QOL score, maximum urinary flow rate, residual urine volume and urinary retention times before and after the treatment.

RESULTSAfter the treatment, Group A showed significantly better improvement in the average 24 h urinary frequency and scores on IPSS and QOL than Group B. No significant differences were found between the two groups in the maximum urinary flow rate and residual urine volume. No acute urinary retention occurred in either group.

CONCLUSIONThe combined use of Tolterodine Tartrate and the alpha-receptor blocker can effectively relieve the symptoms of dysuria, urinary frequency and urinary urgency in patients with BPH-DO, with neither significant adverse effects on the maximum flow rate and residual urine volume nor increase in the incidence of acute urinary retention.

OBJECTIVETo evaluate the efficacy and analyze the prognostic factors of sorafenib treatment in patient with unresectable primary hepatocellular carcinoma (HCC).

METHODSDuring the period from December 2005 to March 2009, 50 patients with unresectable primary HCC of Child-Pugh status A were treated with sorafenib (400 mg, Bid). The tumor response was evaluated with CT or MRI imaging every 6 - 8 weeks according to the RECIST criteria. The overall survival (OS) and time to progression (TTP) were defined as the time from administration of sorafenib to the death or the last follow up and were evaluated by Kaplan-Meier method.

RESULTSThere was no PR or CR, but 28 patients (56.0%) achieved stable disease. The median follow up time was 15 months with a median OS of 14 months and median TTP of 4 months. The common adverse events were dermal reaction (68.0%, 34/50), diarrhea (52.0%, 26/50), hypertension (4.0%, 2/50), hair loss (14.0%, 7/50), myelosuppression (16.0%, 8/50), and liver dysfunction (20.0%, 10/50). However, most of the drug-related adverse events were grade I-II and reversible. The patients with lower tumor burden and without distant metastasis had better prognosis.

CONCLUSIONSoafenib is effective for unresectable primary HCC with tolerable toxicity. Tumor stage is a predominant prognostic factor.

Objective To study the changes of risk factors of cardiovascular disease in the rural community population after intervention. Methods The Beijing Fangshan cardiovascular prevention program was a community-based comprehensive intervention study which was launched from 1991 and ended in 2000 in five communities including three as intervention communities (IC) and two as control communities (CC) in Fangshan, Beijing suburb. The intervention measures were focused on health education and hypertension control. The changes of risk factors of cardiovascular disease in IC and CC were analyzed using random sample in the year 1991, 1995 and 1999, respectively. The risk factors include systolic and diastolic blood pressure(SBP and DBP), body mass index(BMI), serum total cholesterol(TC), triglyceride(TG),high-density lipoprotein cholesterol(HDL), smoking, and drinking. Results From the year 1991 to 1999, the risk factors of cardiovascular disease such as SBP, DBP, smoking rate and drinking rate were reduced in the population of IC. For male in IC, the decline of SBP, DBP, smoking rate, and drinking rate were 1.6 mmHg, 1.1 mmHg, 14. 5% ( P ＜ 0. 01) and 3.7%, respectively. For female of IC, SBP and DBP declined 4.8 mmHg ( P＜0.01) and 3.2 mmHg ( P ＜0. 01), respectively. SBP, DBP and smoking rate in the population of CC had a little reduction while BMI, TC and TG increased in both IC and CC. During the period of 1991 to 1999, most cardiovascular risk factors in the population of IC had net reduction compared to that of CC. Conclusions Except for BMI and lipids, rural community intervention, as focused on health education and hypertension control, has resulted in the reduction of most risk factors of cardiovascular disease.
