International Journal of Pediatrics 2016;43(4):326-329
Objective To investigate the incidence of the common respiratory viruses in children with respiratory tract infection and to compare the results among different ages and to analyze the relationship between wheezing of children and various viruses.Methods Nasopharyngeal secretions of 618 children with respiratory infection hospitalized were assayed for 7 respiratory viruses, including respiratory syncytial virus ,adenovirus, influenza A virus, influenza B virus, parainfluenza virus Ⅰ 、 Ⅱ、 Ⅲ.Results (1) A total of 166 cases, affected with viral etiology,were detected in 618 samples,and the total positive rate was 26.86%.The most common virus was RSV (17.96%), followed by PIV Ⅲ (5.99%), IFA (1.62%), ADV (0.81%), PIV Ⅰ (0.49%).Moreover, 1 case infected with RSV and PIVⅠ was included, with the positive rate 0.16%.(2)The positive rates were different in various ages, with 14d ~ < 1-year 35.04%, 1 ~ < 3-year 18.25%, 3 ~ < 6-year 17.11% and ≥ 6-year 9.26%.(3) There were differences of positive rate of viruses among different respiratory infectious diseases, and capillary bronchitis occupied the highest percentage(47.37%).(4)Among all the detected children, infants were more likely to whee in auscultation of lung, and RSV was the primary etiology.Conclusion RSV,which was the primary viral etiology in children with wheezing, was the most common virus leading to respiratory infection of children, followed by PIV Ⅲ.In the children with respiratory tract infection, the viral infection tends to occur in younger children.
2.The Role of Cytokines and its Advance of Clinical Applications in Atherosclerosis
Chinese Journal of Prevention and Control of Chronic Diseases 2006;0(01):-
Atherosclerosis is a chronic inflammatory disease of the vascular walls. As the essential mediators of inflammation, cytokines play important roles in atherosclerosis. Through widespread and penetrating studies, many cytokines, such as TNF-, IL-1, IL-6 and IFN-, are found involved in the development of atherosclerosis, as well as the related signal transduction pathways such as the NF- B pathway, the JNK / AP-1 pathway, and the JAK / STAT pathway. This implies that cytokines have a favorable perspective of clinical application. A few cytokines are identified as biomarkers, which help the early diagnosis of the disease and estimation of the risk of the clinical vascular events. Meanwhile, great progress has been made on the cytokine-targeted treatment of atherosclerosis, providing a novel therapy in the treatment of the disease.
3.Behavioral logic of community health service institutions in the background of the new healthcare reform based on the grounded theory
Chinese Journal of Health Policy 2017;10(3):54-60
Community health service institutions are the basic tentacles of medical services which directly indicates their relation to the quality and experience of health service.This paper focuses on the behavioral logic of community health service institutions under the background of new medical reform, and looks forward to a perspective on the grassroots practice caused by the reform of medical system through the behavioral analysis of the community health service institutions.The behavioral logic features of the community health service institutions were constructed based on the interview data Nanjing City using the grounded theory.It was found that the realization of public welfare orientation of the aforesaid institutions needs to be completed under the internal and external coordination.The degree of coordination among the interests, orientation, incentives and resource elements will determine the behavior orientation and basic operational practices in the community health service institutions.This study will provide a reference value for the cognition and optimization of healthcare reform policies.
4.Significance of Hidden Rheumatoid Factor IgM,Anti-Cyclic Citrullinated Peptide Antibodies,Antikeratin Antibodies,Combined Test in Diagnosis of Juvenile Idiopathic Arthritis
Journal of Applied Clinical Pediatrics 2004;0(09):-
Objective To explore the significance of hidden rheumatoid factor-IgM(HRF-IgM),anti-cyclic citullinated peptide antibodies(anti-CCP),antikeratin antibodies(AKA)combined test in the diagnosis of juvenile idiopathic arthritis(JIA).Methods The anti-CCP and rheumatoid factors(RF)were tested by enzyme linked immunosorbent assay(ELISA)in serum samples from 60 children with JIA,27 systemic lupus erythematosus(SLE),18 kawaski diseases and 50 healthy children who were enrolled to serve as normal controls.Indirect immumofluorescence method was used to test AKA.Using the QAE-Sephadex-A50 to separate RF then tested HRF-IgM by ELISA.Results Positive anti-CCP were found in sera of 13 patients with JIA(21.7%)and specificity 96.8%.RF were found lower test both with the JIA and other groups(?2=0.17 P=0.68).The results of AKA were similar to the anti-CCP,they were both lower sensitivity and higher specificity.There were 65% sensitivity and 85.3% specificity in the HRF-IgM,and great significant difference in positive rate in JIA and other group(?2=40.22 P=0.0001).Conclusions JIA children in the studied series has a higher detection rate and value of HRF-IgM as compared to the other control groups.HRF-IgM,anti-CCP,AKA combined test in JIA can prove to be a valuable reference index for diagnosing suspected JIA children.

Objective To investigate whether intrathecal administration of corticotrophin releasing factor(CRF) has an efficacy on visceral hypersensitivity in irritable bowel syndrome model rat.Methods Thirty rats were randomly divided into three groups(n=10 ).After establishment of irritable bowel syndrome rat model were intrathecal injected with CRF or preemptive peritoneal injected with CP-154526,which is inhibitor of CRF-1 receptor,and the control group to give saline.After experiment all rat with the method of rectal balloon distention,the perception thresholds and the number of abdominal withdrawal reflexes (AWR) of different balloon volume were observed.Results The perception threshold of intrathecal administration of CRF group was(0.62±0.10)ml and higher than other two groups [(0.52±0.09)ml,(0.56±0.08)ml;F=3.25,P<0.05].At the same time,the number of AWR to the lower balloon content (1.0 ml) was(9.10±1.97)in intrathecal administration of CRF group slightly lower than other two groups[(14.4±1.71),(15.6±2.32);F=29.4,P<0.01],but no difference was found to the higher balloon content (1.5 ml and 2.0 ml).Besides,the areas and OD value of c-fos positive neurons in cornu posterius medullae spinalis in group with intrathecal administration of CRF were significantly lower than other two groups (P<0.05).Conclusion Intrathecal administration of CRF can degrade the visceral hyperensitivity in irritable bowel syndrome model rat,and lower expression of c-fos in CNS is probably involved in the process.

Objective To clone the 5′ non-coding region (NCR) of human interferon-?-inducible protein 10(IP-10), and to identify the transcriptional activity of IP-10 promoter induced by lipopolysaccharide (LPS) in human umbilical vein endothelial cells (HUVEC). Methods Genomic DNA of lymphocytes was isolated from the human blood. With above DNA as the template, the 5'NCR of human IP-10 was amplified by nest polymerase chain reaction (PCR) method. Then, the IP-10 promoter was cloned into luciferase reporter vector, pGL3. The recombined vector was transfected into HUVEC, and then the activity of the luciferase was determined after the cells were stimulated by LPS. Results Human IP-10 promoter was obtained and the pGL3/IP-10 was successfully constructed. Moreover, the activity of luciferase driven by human IP-10 promoter was observed to obviously increase in the HUVEC stimulated by LPS. Conclusion We successfully cloned human IP-10 promoter, constructed luciferase reporter vector driven by the human IP-10 promoter, and confirmed that high transcriptional activity of human IP-10 promoter was induced by LPS in HUVEC. The results supplied an experimental base for the further study of the transcriptional regulation of human IP-10.
