2.The role of the IL 33/ST2 axis in pneumonia
Journal of Medical Postgraduates 2017;30(12):1332-1335
Interleukin 33 (IL 33) is a recently described member of the IL 1 family and widely exists in cells and tissues.IL 33/ST2 axis is mainly associated with the secretion of IL 4,IL 5 and IL 13,which are involved in the initiation or progression of specific Th2 responses.It contributes to the macrophage alternative polarization,dendritic cell regulation,and direct effects on T cells.These effects explain how IL 33/ST2 axis plays contrasting roles in lung diseases.Although IL 33/ST2 axis has been extensively studied in various lung inflammatory diseases,a comprehensive overview on the role of this cytokine in infectious pneumonia is actually lacking.Therefore,we summarize the recent advances on the role of IL 33/ST2 axis in pneumonia caused by various viral,bacterial,fungal and helminth.

Our aim in this study was to determine differentially expressed genes of CD34 + cell from bone marrow and G CSF mobilized peripheral blood. CD34 + cells isolated from bone marrow and G CSF mobilized peripheral blood of the same donor were identified for differentially expressed genes in CD34 + cells using the technique of suppression subtractive hybridization. Eleven genes were expressed with higher levels in CD34 + cells from mobilized peripheral blood, as compared with data of GenBank. These genes included nuclear proteins, transcriptional regulatory molecules, zinc finger proteins and interferon induced molecules. These results demonstrate that there are some differences between the two groups of CD34 + cells. Further study would give us more extensive understanding about mobilization and homing of hematopoietic stem cells.

Objective:
To investigate trends in the disease burden of tumors among children aged 0 to 14 years in China in 1990 and 2019, so as to provide insights into management of pediatric tumors in China.
Methods:
The Global Burden of Disease 2019 data were retrieved from the Global Health Data Exchange, and the mortality and disability adjusted life years (DALYs) of pediatric tumors were evaluated among children at ages of 0 to 14 years in China in 1990 and 2019, and the disease burdens due to pediatric tumors in China were compared with the regions with different social population index (SDI).
Results:
The mortality of tumors decreased from 13.10/105 in 1990 to 4.96/105 in 2019 (a 62.17% reduction) among children aged 0 to 14 years in China, and the DALY rate decreased from 1 118.93/105 to 424.77/105 (a 62.04% reduction). The mortality and DALY rate of tumors decreased from 13.48/105 to 5.38/105, and from 1 147.09/105 to 458.65/105 among male children, and from 12.69/105 to 4.46/105, and from 1 088.22/105 to 384.94/105 among female children. The disease burden of pediatric tumors was concentrated among children at ages of 0 to 4 years. The three highest disease burdens of pediatric tumors were measured in leukemia, brain and nerve system tumors, and lymphoma in 2019. Compared with the regions with different SDI, the largest reductions were seen in the mortality and DALY rate of tumors among children at ages of 0 to 14 years in China, which were still higher than in middle, high-middle and high SDI regions.
Conclusions
The disease burden of tumors declined among children at ages of 0 to 14 years in China in 2019, compared with 1990; however, it is still higher than in middle and higher SDI regions. The disease burden of pediatric tumors was high among children at ages of 0 to 4 years and among male children, with leukemia, brain and nerve system tumors and lymphoma as predominant types.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

Objective To explore the genetic prenatal diagnosis method for acbendroplasia (ACH).Methods During May to November 2007, three ACH pedigrees were diagnosed at the Prenatal Diagnosis Center, Department of Obstetrics and Gynecology, Affiliated Drum Tower Hospital of Medical College, Nanjing University. In family 1, there was a 6-month-old male ACH infant. In family 2, the expectant mother, with 18 weeks of pregnancy, was an ACH patient. Amniocentesis was performed for prenatal diagnosis. The fetus of family 3 was diagnosed as ACH by ultrasound examination on the 39th week of gestation. Umbilical cord blood of this fetus was collected for examination. Totally, three methods, restriction enzyme (Sfc Ⅰ and Msp Ⅰ ) digestion analysis, denaturing high performance liquid chromatography (DHPLC) and sequencing analysis were performed simultaneously to detect the pathogenic mutation of flbroblastic growth factor receptor 3 (FGFR3) for the three ACH families. Results ( 1 ) The DHPLC detection: heteroduplex was detected in the patient of family 1 ; beth the patient and the fetus of family 2 showed heteroduplex results; the result of the fetus of family 3 was also heteroduplea. (2) The enzyme digestion analysis for the PCR products of 10 exon of FGFR3: after Sfc Ⅰ digestion, the PCR products of patients and the fetus of family 1 and 2 showed not only the band of 247 bp, but also bands of 162 bp and 85 bp. But their PCR products could not be digested by Msp Ⅰ , and it only showed the band of 247 bp. For the fetus of family 3, the PCR products could not be digested by Sfc Ⅰ , while after digestion by Msp Ⅰ , bands of 162 bp and 85 bp were shown up. The PCR products of the normal control could be digested by neither Sfc Ⅰ nor Msp Ⅰ. (3) The sequencing results: the heterozygote mutation of 1138 C→A was confirmed in the patient of family 1. The pregnant woman and her fetus in family 2 showed the same result. The heterozygote mutation of C→C was confirmed in the fetus of family 3. The site of 1138 was G homozygote in the normal control The three detection results of the fetus in family 2 were the same as that of the mother, which means that the fetus inherited the same pathogenic mutation from his or her mother. Conclusions Both DHPLC and restriction enzyme digestion analysis could detect the mutation of FGFR3 gene, but DHPLC is more rapid, convenient and sensitive. So DHPLC can be applied to genetic diagnosis and prenatal diagnosis for ACH patients.

OBJECTIVETo analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate.
METHODSFrom December 2011 to June 2012,70 patients with low back pain in operation were evaluated on pain by VAS and function by JOA,and examined by MRI including 39 males and 31 females with an average age of (51.00 +/- 11.89) years ranging from 29 to 72 years old. Among them, 54 cases had lumbar endplate Modic changes involving 15 cases in types Modic I ,21 cases in type Modic II, 11 cases in type Modic III ,mixed type Modic in 7 cases (eliminated for too few cases). Modic area changes and corresponding vertebral area were measured on MRI T2 median sagittal. The areas of two ways were compared to yield the rate of changes for Modic, for multisegmental Modic changes to calculate the total ratios. A correlation was observed among JOA, VAS and the rate of Modic changes.
RESULTSThe correlation coefficient of change rate of Modic I with JOA score was r = -0.308, P = 0.048 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic I with VAS scores was r = 0.428,P = 0.021 < 0.05, there was a positive correlation. The correlation coefficient of change rate of Modic II with JOA score was r = -0.375, P = 0.043 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic II with VAS score was r = 0.352, P = 0.041 < 0.05, there was a positive correlation. The area change rate of Modic III had no significant correlation with low back pain degree (P > 0.05).
CONCLUSIONModic I and II area changes rate of of patients with low back pain is closely related to the degree of pain low back pain, Modic III area changes rate is not significant correlated to the degree of lower back pain.

AIM:To screen the gene expression profiles of normal gastric mucosa,primary gastric cancer and metastatic lymph nodes by gene expression microarray and the associated genes with lymph node metastasis by bioinformatics. METHODS:The differentially expressed genes of nontumorous gastric mucosa (group A),primary gastric cancer (group B) and metastatic lymph nodes (group C) were screened by gene expression microarray obtained from Affymetrix company. The results were further analyzed by bioinformatic software including Gene Expression Profiles Analysis of Cohort Experiment,Gene Ontology Enrichment Analysis and Pathway Significant Analysis. The expression of TLN1 in group A,B and C were confirmed by real-time reverse transcription PCR. RESULTS:278 genes were persistent up-regulated in group A,B,C,which participated mainly in immunologic responses,cell adhesion,phosphate transport,inorganic anion transport,cell chemotaxis,cell motility and signal transduction. While 387 genes were persistent down-regulated in group A,B,C,which were concerned with digestion,glucide metabolism,lipid metabolism,protein metabolism,one-carbon compound metabolism,nitrogen compound catabolism and cell adhesion. The pathway analysis suggested that integrin-mediated cell adhesion pathway were abnormally regulated. These genes including THBS1,TLN,CAPN3,ITGAX,SORBS1,CAPN6,CAPN9 were continuous up-regulated or down-regulated in integrin-mediated cell adhesion pathway. The expressions of TLN1 in group A,B,C were 0.0000342?0.0000711,0.1064?0.1251 and 0.2886?0.3529,respectively. The expression of TLN1 in metastatic lymph nodes was significantly higher than that in nontumorous gastric mucosa and primary gastric cancer (P
