With the development of the neonatal intensive care technology,the livability of premature infants arises greatly.But the evidently increased handicap and unknowable prognosis have brought series of social problems.The author assumed that!abandoning or ending treatment of premature infants who have no social value after cure and who are about to die soon after born correspond to ethics principle.Hospital ethics committee should play role in the decision making of cure.

Inflammasome is a multi-protein complex which plays an important role in innate immune defense,and can adjust the activation of caspase-1 and promote the production of cytokines. NLRP3 is an important member of inflammasome Nod-like receptor(NLR)family,and its activation and expression occur mainly in macrophages and dendritic cells. NLRP3 can sense the pathogen associated molecular patterns(PAMPs)and damage associated molecular patterns(DAMPs)and initiate the inherent immune response,which plays an important role in the pathogenesis of autoimmune diseases. This article reviewed the advances in study on NLRP3 in autoimmune diseases.

Objective The immature platelet fraction (IPF) could be detected quantificationally in Sysmex XE-2100 with the software of XE-pro and IPF master.The study aimed to perform the methodological evaluation of IPF detection and investigate the clinical significance for the monitoring for bone marrow hyperplasia in cancer chemotherapy patients.Methods The high-level, middle-level and low-level whole blood samples were randomly chosen for detection repeatly 20 times to obtain interrun coefficient of variation (CV) for evaluation of the precision and reproducibility. Integrated quality controls were determined for continuous 20 days to obtain intrarun CV, and the stability and carryover was investigated.Furthermore, the correlation between results from Sysmex XE-2100 and results from flow cytometry was assessed.182 healthy subjects and 130 cancer patients undergoing chemotherapy were selected and the latter were divided into two groups according to platelet counts after therapy, one was normal PLT group, the other was decreased PLT group.The IPF of either group was measured and was compared with each other.Results The precision of IPF for high-level, middle-level and low-level were 4.71%, 4.33% and 4.95%, respectively, they were less than 5%.The interrun CV of IPF detection for middle-level and low-level were less than 5%.The interrun CV of IPF detection for high-level were less than 10%.The carryover ranged from 0.6% to 2.7%,and the average rate was 1.2%.A good correlation for IPF detection was shown between results from Sysmex XE-2100 and flow cytometry(r = 0.880 9,P < 0.01).Regarding clinical utility of IPF detection in treatment monitoring for chemotherapy effect, the median of IPF levels in decreased PLT group, normal PLT group,control group were 14.45% ,7.35% and 15.68%, respectively.There was significant difference among the three groups (H =49.032,P <0.01 ).The IPF level was higher in decreased PLT group than normal PLT group (t = -5.681, P < 0.O1 ), and was lower in normal PLT group after chemotherapy than the control group (t = -6.662 ,P <0.01 ).Conclusions The determination of IPF by the Sysmex XE-2100 owns high precision and good stability. IPF is an effective marker for evaluation of thrombopoietic condition in the cancer chemotherapy patients.

Objective:Population-based cancer registration data were used to analyze stomach cancer epidemiology in China. Meth-ods:Stomach cancer data were retrieved from the National Central Cancer Registry Database, and incident and death cases were esti-mated. The trend of stomach cancer was analyzed. Results:Approximately 424,000 new cancer cases and 298,000 cancer deaths oc-curred in China in 2012. The incidence and mortality rates of stomach cancer in urban males and females remained stable in 2000-2012, whereas the rates in rural males increased and less changes were observed in rural females. After age standardization, both inci-dence and mortality rates significantly decreased. The five-year age-standardized relative survival rate was 27.4% (95%CI: 26.7%-18.1%) in 2003-2005. Conclusion:Stomach cancer is a common cancer, which has heavy burden in China, particularly in rural areas. Ef-forts should be exerted for the prevention and control of the disease.

Objective To evaluate the childhood asthma control test(C-ACT) on the assessment of asthma by exploring the correlations among C-ACT,disease severity,the control level of pediatric asthma,disease partition and the changes in the pulmonary function as well as the score range,and to evaluate the feasibility and effectiveness of C-ACT's application to guide children's asthma control.Methods Two hundred and five children with asthma in the Pediatric Asthma Outpatient of Xiamen Hospital of Fujian University of Traditional Chinese Medicine from October 2011 to October 2015 were enrolled and randomly divided into control group and experimental group by random number table.The patients in the experimental group were monitored by the C-ACT with corresponding guidance,while patients in control group were treated without the monthly guidance of C-ACT after C-ACT involvement at the first time.C-ACT questionnaire score surveys were completed by all patients and their parents under the guidance of asthmatic specialists or nurses.Pulmonary function,disease severity and disease partition and the control level of pediatric asthma were detected and evaluated by doctors before and after treatment.The correlation between the results of C-ACT and the changes in the clinical indicators was assessed,and the improvement of lung function and the control rate of asthma were evaluated in 2 groups after 1 year.Results (1) There was no significant difference in gender,age and disease severity distribution based on the results of pulmonary function assessment between the control group and the experimental group (all P > 0.05).(2) The C-ACT scores in normal,slight abnormal,moderately abnormal and severely abnormal pulmonary function were (24.79-± 2.20) scores,(21.67 ± 1.93) scores,(17.07-± 2.01) scores and (12.67 ± 1.81)scores,respectively,which showed the pulmonary function had a positive correlation with C-ACT scores (F =314.0,P < 0.000 1).(3)Assessment of the reliability of C-ACT:the α value of Cronbach's coefficient for the scale was 0.867,which showed the high reliability.The correlation coefficients between the C-ACT score and the percentage of predicted value of forced expiratory volume in one second(FEV1%),the percentage of peak expiratory flow in the predicted value (PEF%) were 0.683 and 0.712,respectively,which also showed the strong reliability.(4) C-ACT scores in intermittent attacks of asthma,slight persistent asthma,moderate persistent asthma,severe persistent asthma were (24.47 ± 2.26) scores,(22.17 ± 1.86) scores,(17.42 ± 2.52) scores and (13.27 ± 2.11) scores,respectively,which showed the severity of asthma was positively associated with C-ACT scores (F =244.0,P < 0.000 1).(5) C-ACT scores in controlled,partly controlled and uncontrolled asthma were (24.32 ± 2.34) scores,(18.87 ± 1.95)scores and (14.03 ± 1.32) scores,which showed the control levels of asthma had a positive association with C-ACT scores(F =394.0,P < 0.000 1).(6)C-ACT scores in different disease partitions of green,yellow and red area were (24.72 ± 2.04) scores,(18.17 ± 2.03) scores and (15.06 ± 1.93) scores,which showed the diseases partition had an association with C-ACT scores (F =367.2,P < 0.000 1).(7) After treatment of 3 months,6 months and 12 months,the control rates in the control group were 28.71%,67.33%,81.19%,but they were 44.23%,79.81%,95.19% in the experimental group respectively.The control rates were higher in the experimental group than those in the control group,and the differences were significant (x2 =5.318,4.114,9.722,all P < 0.05).Conclusion The C-ACT is highly correlated with pulmonary function,and our study show the C-ACT score range can help to make a quick assessment of disease severity,disease partition and the control level of children asthma.The application of C-ACT for the treatment of asthma has a good effect and it can be recommended and applied to childhood suitable for the promotion and application of children asthma clinics and community medical institutions at all levels of hospitals.
