Chinese Journal of Medical Imaging Technology 2009;25(10):1909-1911
Ultrasound brain perfusion imaging can evaluate brain perfusion in normal and pathological conditions. After basilar stent implantation, contrast-enhanced ultrasound (CEUS) can show normal visualization of color flow within the stent and provide essential functional information by evaluation of blood flow velocities. Furthermore, CEUS can estimate the volume of brain hemorrhage and readily identify residual tumor. CEUS can be used in thrombolysis, and will be applied in cerebral trauma. The value of CEUS in brain perfusion imaging was reviewed in this article.

Objective To explore the value of contrast-enhanced ultrasonography(CEUS) in brain injuries. Methods ① Models of graded brain trauma were created in brains of 10 healthy mongrel dogs after the animals were anesthetized and the cranium were removed. Conventional ultrasonography(US) and CEUS were performed to observe the characteristics of traumatic region. ② Thirteen patients with traumatic brain injuries were collected to perform intraoperative ultrasonography. The location, depth, size, internal echo and boundary of traumatic brain injuries were clearly displayed. Eight injury sites were chosen to undergo CEUS. Results ① Twelve injury sites in brains of 10 dogs were detected,and CEUS were peformed in 10 lessions, of which 1 was diagnosed with cerebral contusion, 1 with cerebral contusion and cerebral hemorrhage, 7 with intracerebral hematoma, 2 with ventricular hematoma, 1 with blood vessels in intracerebral hematoma. ② Fifteen lesions were detected by preoperative CT scan, but 18 lessions were detected by intraoperative ultrasound. During operation epidural hematomas in 4 cases were detected. After CEUS,the area of lessions was clearly revealed to be extended, the hemorrhage area was exempt from enhancement while peripheral normal cerebral tissue was homogenously enhanced. Conclusions Conventional ultrasonography could display brain injuries. In case of accurate intraoperative encephalocele, intraoperative untrasound conduces to discover delayed intracranial hematoma. Different traumatic brain injuries had their special CEUS findings.

Objective To determine the influence of abiraterone acetate (AA) on neuroendocrine differentiation (NED) in metastatic castration-resistant prostate cancer (mCRPC) and the prognostic predicting value of the serum NED markers in mCRPC patients treated with AA.Methods We conducted an analysis in 115 chemotherapy-naive mCRPC patients who were treated with chemotherapy in Renji hospital from 2013 to 2017.The median age was 70,ranged from 65 to 76 years old.The median CgA,NSE and PSA levels were 101.1 ng/ml (78.5-150.0 ng/ml),13.4 ng/ml (10.5-17.6 ng/ml) and 38.8 ng/ml (11.2-123.2 ng/ml),respectively.Among them,48 cases were classified as the group without AA treatment.The other 67 cases were classified as group after AA failure.In group without AA treatment,the median CgA,NSE and PSA levels were 109.1 ng/ml(80-151.5 ng/ml);13.8 ng/ml(10.8-18.2 ng/ml) and 39.2 ng/ml (8.6-200 ng/ml),respectively.In group after AA failure,the median CgA,NSE and PSA levels were 105.4 ng/ml(78.8-175.5 ng/ml),13.8 ng/ml(10.8-17.6 ng/ml) and 39.0 ng/ml(8.4-219.8 ng/ml),respectively.In the group with serial evaluation of NED markers during AA treatment,the median serum CgA,NSE levels at baseline were 115.9 ng/ml(90.1-201.5 ng/ml),13.3 ng/ml (10.4-18.1 ng/ml),respectively.The endpoints were PSA PFS(progression-free survival) and radiographic PFS (rPFS).Results In 34 patients with serial evaluation,serum NED markers level in 19 patients increased after the failure of AA treatment.Median serum CgA and NSE levels were 115.9 ng/ml(90.1-201.5 ng/ml)and 13.25 ng/ml (10.37-18.14 ng/ml) at baseline.Median serum CgA and NSE levels were 129.6ng/ml (75.5-230.5 ng/ml) and 14.7 ng/ml (11.8-19.1 ng/ml) after 6 months treatment,respectively.The median serum CgA and NSE levels were 130.4 ng/ml (95.7-205.7 ng/ml) and 15.2 ng/ml(12.4-18.7 ng/ml) at the time of failure of AA treatment,respectively.There was no significant difference of NED markers between baseline and failure of AA treatment (P =0.243).In logistic univariate analysis,AA treatment and its duration were not independent factors influencing NED(P =0.30;P =0.52).Compared with the NED markers elevation group in the first 6 months of AA treatment and baseline supranormal NED markers group,the NED markers decline group(PSA PFS(17.1 vs.10.4 months,P < 0.001) and rPFS (17.0 vs.10.4 months,P =0.003)) and baseline normal NED markers group(PSA PFS(14.1 vs.9.5 months,P =0.001) and rPFS(16.4 vs.10.5 months,P < 0.001)) has a longer median PSA PFS and rPFS respectively.In multivariate Cox analysis,baseline NED markers level and NED markers variation during the first 6 months of AA treatment remained significant predictors of rPFS(P < 0.05),and PSA-PFS (P < 0.05).Conclusions We found there was heterogeneity in changes of NED markers in different mCRPC patients during AA treatment,and AA might not significantly lead to progression of NED of mCRPC in general.Serial CgA and NSE evaluation might help clinicians guide clinical treatment of mCRPC patients.Serum NED markers elevation during the first 6 months of AA treatment and elevated baseline NED markers levels indicated poor prognosis in mCRPC treated with AA.

OBJECTIVETo investigate the clinical and hematological features and prognostic factors of primary myelofibrosis (PMF) patients in Shanghai and surrounding area of Shanghai, China.
METHODSThe clinical manifestations, laboratory parameters and survival were retrospectively analyzed in 75 PMF patients diagnosed from Jan, 1996 to Dec, 2013 in our hospital and were compared with those of Chinese subjects from Tianjin and foreign Caucasian patients, respectively. Comparison of categorical variables was performed by χ² test. Survival was estimated using the Kaplan- Meier method. Log- rank test was used to compare survival date. A Cox model was used for multivariate analyses.
RESULTSThe median age of the 75 patients was 56(19-81) years old. There were 51(68%) patients with HGB less than 100 g/L. The median value of HGB was 83 g/L. Similar with those from Tianjin, the patients in our study were significantly younger with higher proportion of severe anemia and lower platelet counts when compared with foreign Caucasian patients. Using IPSS and dynamic international prognostic scoring system (DIPSS) model, the survival curves of intermediate- 1, intermediate- 2 and high risk groups were significantly different. In univariate analyses, variables significantly correlated with poor prognosis were systemic symptoms, HGB<100 g/L, HGB<80 g/L, PLT ≤ 100 × 10⁹/L, WBC<10 × 10⁹/L and blood blasts ≥ 0.01. Multivariate analysis identified IPSS and HGB < 80 g/L as independent risk factors for survival.
CONCLUSIONChinese PMF patients may have characteristics of younger age at onset with more severe anemia. However, IPSS and DIPSS model are still suitable for Chinese patients to predict survival. To increase the weight of anemia severity may provide a better prognostic stratification for Chinese patients with PMF.

OBJECTIVETo explore the prognostic significance of Ph-positive and/or BCR-ABL positive acute lymphoblastic leukemia (Ph⁺ ALL).
METHODSA retrospective analysis of 72 patients with Ph⁺ ALL to probe prognostic factors including sex, age, high white cell counts at diagnosis, additional chromosome abnormality, BCR-ABL transcripts type, imatinib based therapy, allo-HSCT and complete remission (CR) after one-course induction on the outcomes of Ph⁺ALL patients.
RESULTSOf 72 patients with median age 40.5 (13-68) years, 38 patients received imatinib plus chemotherapy. With median follow-up of 11 (0.2-96) months, total CR rate in patients receiving imatinib plus chemotherapy was higher than of patients receiving chemotherapy only (97.4% vs 62.3%, P=0.019). High white blood counts at diagnosis or additional chromosome abnormality had no effects on CR rate. 2-year overall survival (OS) and disease free survival (DFS) in imatinib plus chemotherapy group were (28.9±7.4) % and (25±7.4) %, respectively, which were higher than those in chemotherapy group (P<0.001). OS rate in HSCT group was significantly higher than that in non-HSCT group[ (61.1±11.5) % vs (5.6±3.1) %, P<0.001]. Multivariate prognostic analysis for OS showed that imatinib-based therapy [RR=0.413 (95% CI 0.237-0.721), P=0.002], allo-HSCT [RR=0.175 (95% CI 0.075-0.389), P=0.000] and CR after one-course induction [RR=0.429 (95% CI 0.245-0.750), P=0.003] were of importance for survival.
CONCLUSIONallo-HSCT was an optimal choice for Ph⁺ALL patients. Imatinib-based therapy could increase CR rate, maintain CR duration and decrease relapse, resulting in more chance of HSCT. Imatinib improved the outcomes of Ph⁺ALL patients who were not eligible for HSCT.
