Objective To investigate the differentiatial diagnostic value of 99Tcm-methoxyisobutylisonitrile ( MIBI ) SPECT combined with localizable CT in the evaluation of oxygen intervention for suspicious lung lesions,and to establish a cost-effective imaging modality in the detection of malignant lung lesions.Methods From September 2008 to March 2009,47 consecutive patients with suspicious malignant lung lesions underwent 99Tcm-MIBI SPECT/CT prospectively. Patients with suspicious pneumonia were treated with antibiotics for about 4 d before imaging. All patients were cannulized with a nostril tube for oxygen inhalation before 99Tc-MIBI injection. SPECT combined with localizable CT of the chest was performed at 10 min and 2 h after 99Tcm-MIBI injection. The uptake ratios of lesion to contralateral normal lung parenchyma(early uptake ratio:EUR and delayed uptake ratio:DUR) were compared using independent-samples ttest. In addition,the diagnostic efficiency of uptake ratios of lung lesions was analyzed with receiver operating characteristic (ROC) curve. Results Forty-seven patients ( primary lung cancers:32,metastatic tumors of the lung:4,benign lung diseases:11 ) had 51 lung lesions,including 39 malignant and 12 benign lung lesions. The sensitivity,specificity,accuracy,positive predictive value (PPV),and negative predictive value (NPV) were 94.9% (37/39),83.3% ( 10/12),92.2% (47/51),94.9% (37/39) and 83.3% ( 10/12),respectively. The EUR of malignant lesions was 2.95 ± 1.16,whereas of benign lesions was 1.43 ±0.33. The DUR of the malignant lesions was 3.19 ± 1.74,whereas of benign lesions was 1.60 ±0.32. Both EUR and DUR were significantly different between malignant and benign lung lesions,respectively (t= -4.44,-3.12,respectively,both P<0.01). The ROC curve showed that EUR value ≥1.625 provided the sensitivity of 97.4% (38/39) and specificity of 83.3% (10/12); DUR value ≥ 1.75provided the sensitivity of 94.9% (37/39) and specificity of 83.3% (10/12). Conclusion 99Tcm-MIBI SPECT combined with localizable CT imaging in oxygen intervention has a potential value in differentiating malignant from benign lung lesions.

OBJECTIVETo study the effects of using Compound Danshen Injection (CDI) and low molecular weight heparin (LMWH) on early severe preeclampsia women.
METHODSRetrospective analysis was carried out in 95 patients with early severe preeclampsia from October 2008 to January 2011. They were assigned to 3 groups based on anticoagulant drugs. The routine therapy of magnesium sulfate (MgSO4) was given to the MgSO4 group (40 cases); the MgSO4 + CDI was given to those in the CDI group (23 cases), the MgSO4 + LMWH group was given to those in the LMWH group (32 cases). The general data of all patients were collected to analyze their effects on labor, postpartum hemorrhage, reasons for terminating the pregnancy, and maternal complications.
RESULTS(1) The average gestational week (weeks) of terminating the pregnancy was 31.7 +/- 1.9 in the MgSO4 group, 33.0 +/- 1.8 in the CDI group, and 32.8 +/- 1.7 in the LMWH group. The average weight of newborn babies (g) was 1 450.5 +/- 402.3 in the MgSO4 group, 1 582.2 +/- 332.5 in the CDI group, and 1 590.0 +/- 340.1 in the LMWH group. There was no obviously difference in the average gestational weeks or the average weight of newborn babies among the three groups. (2) The way of terminating the pregnancy was uterine-incision delivery. The main reasons for operation were sequenced as maternal complications, unsatisfied control of the blood pressure, and fetal distress. (3) The maternal complications in the three groups were sequenced as renal failure (12 cases), placental abruption (9 cases), hemolysis, increased liver enzymes and low platelet (HELLP) syndrome (8 cases). Sixteen (40.0%) had complications in the MgSO4 group, 12 (52.2%) in the CDI group, and 15 (46.9%) in the LMWH group. No statistic difference existed among the 3 groups.
CONCLUSIONSLMWH and CDI were helpful to improving the therapeutic effects of severe preeclampsia patients. They did not increase adverse drug reactions. They seemingly had effects on prolonging the gestational week.

OBJECTIVETo explore the risk factors of acute lymphoblastic leukemia (ALL) recurrence in adult patients and establish a prognosis index (PI) calculation model in order to improve the prevention strategy of ALL in adults.
METHODS104 adult ALL patients from Blood Diseases Hospital & Chinese Academy of Medical Sciences between August 2008 and November 2011 were enrolled. COX proportional hazards regression stratified by Dummy variable was used to set up the prediction model; Kaplan-Meier method and Log-rank test were used to estimate and compare the survival. After calculated individual PI value, patients' expected survival should be estimated by groups.
RESULTSThe overall median survival of adult ALL patients was 22.00 months (95% CI 17.00-27.00). COX regression analysis showed that chemotherapy group patients had a higher risk of recurrence than of ASCT group while setting treatment as the dummy variable (RR=2.052, 95%CI 0.877-4.799, P=0.007). Stratified Analysis showed that the risk factors of B-ALL recurrence in adult patients included HGB <100 g/L (RR=0.186, 95% CI 0.068-0.512, P=0.001), CNSL (RR=7.767,95% CI 2.951- 20.433, P=0.001), number of consolidation chemotherapy<3 (RR=0.445, 95% CI 0.211-0.940, P=0.034) and Ph chromosome positive (RR=2.771, 95% CI 1.353-5.674, P=0.005). Grouped by the PI value, the expected survival of each individual patient could be estimated as PI=0.58 base.
CONCLUSIONHGB, CNSL, number of consolidation chemotherapy and Ph chromosome were independent risk factors of B-ALL recurrence in adult patients. PI value could predict the survival of adult ALL patients and provide reference for individual therapy and prognostic evaluation.

OBJECTIVETo investigate the safety and efficacy of low-concentration inhaled nitric oxide (NO) in the treatment of hypoxic respiratory failure (HRF) among premature infants.
METHODSSixty premature infants (gestational age ≤ 34 weeks) with HRF were randomized into NO and control groups between 2012 and 2013, with 30 cases in each group. Both groups received nasal continuous positive airway pressure (nCPAP) or mechanical ventilation. NO inhalation was continued for at least 7 days or until weaning in the NO group. The general conditions, blood gas results, complications, and clinical outcomes of the two groups were analyzed.
RESULTSThe NO group showed significantly more improvement in blood gas results than the control group after 12 hours of treatment (P<0.05). After that, the change in oxygenation status over time showed no significant difference between the two groups (P>0.05). There were no significant differences in total time of assisted ventilation and duration of oxygen therapy between the two groups (P>0.05). The incidence of bronchopulmonary dysplasia (BPD), patent ductus arteriosus, necrotizing enterocolitis, retinopathy of prematurity, and pneumothorax in infants showed no significant differences between the NO and control groups (P>0.05), but the incidence of IVH and mortality were significantly lower in the NO group than in the control group (7% vs 17%, P<0.05; 3% vs 13%, P<0.05).
CONCLUSIONSNO inhalation may improve oxygenation status and reduce the mortality in premature infants with HRF, but it cannot reduce the incidence of BPD and the total time of mechanical ventilation or nCPAP and duration of oxygen therapy. NO therapy may have a brain-protective effect for premature infants with HRF and does not increase clinical complications.
