Objective To evaluate the prognostic factors in predicting relapse of childhood acute lymphoblastic leukemia (ALL) treated with CCLG-2008 protocol. Methods From December 1st 2008 and December 31st 2012, 358 patients diagnosed with ALL and treated with the CCLG-ALL 2008 protocol were enrolled in this study. All patients were followed up until September 1st, 2015. Prognostic impact of clinical features, response to treatment, biological features were analyzed and multivariate analysis of predicted value was performed by Cox-regression analysis. Results After treatment of CCLG-ALL 2008 protocol, 79 patients suffered from relapse. The relapse rate in the standard-risk, intermediate-risk and the high-risk groups were 13.3%, 17.6%, and 41.3%, respectively (P?100×109/L, non-remission in 15th day of induction (M3), the level of minimal residual disease (MRD) on 12w (12w-MRD)?>10-4 were signiifcantly higher, their corresponding hazard ratio were 3.17 (1.58?~?6.36), 1.87 (1.07?~?3.30), and 1.90 (1.12?~?3.20), respectively (P?10-4 were the independent prognostic factors for childhood B-ALL.

Objective To explore the clinical effect of customized mask on the leakage and skin injury of patients with noninvasive ventilation.Methods Totals of 80 patients treated with noninvasive ventilation were randomly divided into treatment group and control group,with 40 cases in each group.The patients in treatment group received combined application of the customized mask and the face mask ventilator,while control group received the mask ventilator solely.The adverse reactions in two groups were compared.Results The ratio of adverse reactions such as leakage and skin injury of treatment group was 2.5％ and 5％,while that of control group was 22.5％ and 52.5％,and the differences between two groups was statistically significant (x2 =5.60,22.03,respectively;P ＜0.05 or P＜0.01).Conclusions The adverse reactions in noninvasive ventilation such as leakage and skin injury can be effectively avoided by applying the customized mask.

Visual prostheses have the potential to restore partial vision for the blinds. The stimulating electrodes generate reproducible phosphenes. Still limited by the low resolution vision used in visual prostheses nowadays, it is important to optimize the image processing strategies in order to deliver better visual information to the patients. This paper presents a review of the current research progress on the image processing strategies based on visual attention models under simulated prosthetic vision and related psychophysics.

The purpose of this study was to explore the significance of abnormal karyotype in diagnosis and prognosis estimation of myelodysplastic syndrome (MDS). Chromosome analysis were performed in 306 cases of MDS using the short-term culture of bone marrow cell and G-banding technique, and in partial cases FISH technique was used for this analysis. 93 out of 306 cases were followed up. The results showed that 144 cases (47.1%) had clonal chromosome aberrations. The most common chromosomal aberrations included +8, translocation, complex or high complex karyotype, -7/7q-, 20q-/-20, trisomy 1 or partial trisomy 1, +11/+11q-, -9/9q-, +9/9q+, -Y, dup(1q), +21. The rate of abnormal karyotype in refractory anemia with erythroblasts (RAEB) and refractory anemia with erythroblasts-transformation (RAEBT) were much higher than in refractory anemia (RA) and refractory anemia with sideroblasts (RAS) (P < 0.05). The rate of abnormal karyotype among those cases with mutagen contact history were higher than those in cases without mutagen contact history. The patients with abnormal karyotype had a mean survival time much shorter than patients with normal karyotype (P < 0.005) and had a higher risk transforming into acute leukemia (P < 0.05). The worst outcome was observed in those patients with a complex or high complex karyotype, -7/7q- and trisomy 11. In conclusion, MDS is highly heterogeneous disorders and karyotype analysis is helpful for its diagnosis, treatment selection and prognosis estimation.

Objective to compare and contrast the diagnosis results on 2D and 3D Ultrasonogrpahy against MRI. Method A 2D Ultrasonography was applied during a conventional prenatal sonography checking with a 3D Sonography assessment subsequently conducted to follow up on 49 fetus suspected of brain malformation.Furthermore, a MRI scan was taken within 24 hours after the 3D Sonography checking in our hospital as a final test. Data collections from all three assessments were completed, and an analysis of the comparisons of these three methods were done. Results Among these 49 fetus with confirmed or suspected brain malformation, there were two cases of misdiagnoses of Dandy-Walker Malformation assessed by 2D sonography, with a misdiagnosis rate of 40％, (P ＜ 0.05) indicating a statistically significant result; misdiagnosis rate of Fetal Ventriculomegaly and Isolated Broadening Posterior Fossa were calculated as 26.7％ and 33.3％ respectively (P ＜0.05), a statistically significant result. Overall, there were two cases with Cerebellum Malformation, from in which one case was identified by MRI, and the other one was misdiagnosed, with a misdiagnosis rate of 50.0％.In total, there were 2 cases of Holoprosencephaly, in which one was identified by Prenatal MRI, and the other was misdiagnosed (P ＜ 0.05), a statistically significant result. Conclusions All three assessments of 2D ultrasonography, 3D ultrasonography and MRI have their own advantages and disadvantages. In short, 2D Sonography is suggested to be applied for screening out cases with brain malformation, together with 3D Sonography as a complementary assessment. MRI can also be an effective and significant complement for sonography in completing and readdressing the final ultrasonic results.

Objective To evaluate the predictive role of TEL/AML1 fusion gene in protocol CCLG-ALL-2008 and to identify relevant factors influencing the outcome of ALL with TEL/AML1 fusion gene. Methods Ninety-nine patients with ALL harboring TEL/AML1 fusion gene (positive) and 329 cases without any specific fusion genes (negative) at diagnosis of B-lineage ALL from June 2008 to December 2014 were enrolled and their clinical and biological features were analyzed. Following-up ended in October 2015, the survival status was calculated by K-M curve and prognostic factors were analyzed by COX model. Results There were no differences between the two groups in age, white blood cell at the diagnostic stage, and treatment responses at 4 time points, namely, prednisone good response on day 8, M3 status of BM on D15, and the minimal residual disease (MRD) more than 1.0×10-3 on day 33 and 12th week. During the follow-up period, the relapse rate was lower in the positive group than that in the negative group (14/99 vs 69/329), the mortality rate of the negative group was twice of that in the positive group (55/329 vs 8/99). The five-year overall survival (OS) rate, relapse-free survival (RFS) rate and event-free survival (EFS) rate of the positive group were (86.1 ± 4.9)%, (80.7 ± 5.1)% and (78.9 ± 5.1)%, respectively, and (79 ±2.8)%, (72± 3.1)%, and (69.6+ 3.1)% for the negative group as well. COX regression analysis indicated that relapse and MRD level at the 12th week were independent prognostic factors on OS, RFS, and EFS (P<0.05) for the two groups. Conclusions TEL/AML1 fusion gene could be regarded as a relatively good indicator of risks in ALL children treated by CCLG-ALL-2008 protocol. ALL patients with TEL/AML1 are recommended to receive more intensive therapy including hematopoietic stem cell transplantation when the patients were high level of MRD on the 12th week after treatment.

In China, with the restructuring of health care system moving forward, private community health facilities have been playing a complementary but increasingly important role in providing public health and basic medical care services in urban areas. However, only limited evidence is available concerning the service functions of private community health facilities in China. The aim of this study was to explore the functions of private community health stations (PCHSs) to provide evidence-based recommendations for policy-making and practice in the development of urban community health services systems. A total of 818 PCHSs and 4320 government-sponsored community health stations (GCHSs) located in 28 cities of China were investigated in 2008. The percentages of stations that provided health services and the annual workload per community health worker (CHW) were compared between the two types of institutions. The results showed that the percentages of PCHSs providing public health services were significantly higher than those of GCHSs (P<0.05); but no significant differences were found in the percentages of basic medical services providing between PCHSs and GCHSs (P>0.05). The annual workloads of all the public health services and basic medical services per CHW in PCHSs were lighter than those in GCHSs (P<0.05), except for resident health records establishment and health education materials distribution (P>0.05). At present, the GCHSs are still the mainstream in urban China, which will last for a long period in future. However, our findings showed that the annual workloads of CHWs in PCHSs were no heavier than those in GCHSs, and the PCHSs were willing to provide public health services. In view of current inadequacy of health resources in China, it is feasible to further develop PCHSs under the guidance of the government, given that PCHSs can perform the basic functions of community health services, which is useful for the formation of public-private partnerships (PPP) and the improvement of community health services.
