ABSTRACT
Objective@#To understand the current status of health education faculty in Yuzhong District of Chongqing, so as to explore the implementation path to improve the construction of health education faculty.@*Methods@#In August 2023, stratified random sampling was used to directly select a total of 555 teachers and school doctors from 17 schools in 11 streets of Yuzhong District, who were invited to conduct a questionnaire survey. A total of 409 fulltime or parttime health education teachers were included in the analysis of the results. Both χ2 test and Fisher exact probability method were analyzed for compare the differences in the frequency of conducting health education courses and specializing in specializing areas among different plant health education teachers in Yuzhong District.@*Results@#Health education course faculty were mainly female teachers, accounting for 81.66%. The proportions of physical education (PE) teachers, school doctors, head teachers and teachers from other disciplines were 14.67%, 8.31%, 62.84%, 14.18%, and the class teachers (81.33%) and school doctor (80.95%) were found of the highest proportion of providing health education courses, and the teaching section was mainly elementary school (first to third grade: 42.30%, fourth to sixth grade: 44.74%). Among the teachers, school doctors had the highest proportion (88.24%) of receiving training related to health education courses. And there was a significant stastical difference in the frequency of conducting health education classes among PE teachers, school doctor, head teachers and the teachers of other courses (χ2=54.46, P<0.01). The results of Fisher exact probability method showed that the differences in selfassessment of the most and least skilled areas among PE teachers, school doctor, head teachers and teachers of other courses were statistically significant (P<0.01).@*Conclusions@#Health education faculty in Yuzhong District is mainly composed of PE teachers, school doctor, head teachers and teachers of other courses. The standardized training and assessment of teaching for school doctor could promote the school nurse group developing into specialized health education faculty.
ABSTRACT
OBJECTIVE@#To investigate the gene-carrying rate and genetic types of thalassemia among the couples of child-bearing age in Ding'an, Hainan province.@*METHODS@#A total of 1742 couples at child bearing age in the region were screened for thalassemia by detecting the mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV). If the sample data of either spouse of couples was tested as MCV<82 fl and /or MCH<27 pg, both samples of the couple would be further assayed by hemoglobin electrophoresis. Those samples of HbA2 2.5 % or HbA2>3.5 % were judged as positive in the preliminary screening, then subjected to genetic diagnosis of thalassemia.@*RESULTS@#478 cases out of 1 742 couples of child bearing age were diagnosed as thalassemia gene mutation, and the gene-carrying rate was 13.72 %. In those carriers, 42 couples were diagnosed with the same type of thalassemia, accounting for 3.67 %. The gene-carrying rate of α-thalassemia, β-thalassemia and αβ-thalassemia was 9.56%, 3.10% and 1.06 % respectively.@*CONCLUSION@#The Ding'an area in Hainan Province is an area with high incidence of thalassemia, and the main genotype is α-thalassemia, showing a distribution of local characteristics. The government should make efferts to popularise the screening for thalassemia, so as to effectively prevent the birth of children with thalassemia major.

After a description of the concept of research frontier, advantages and disadvantages of qualitative and quantitative research frontier analysis methods, application of qualitative and quantitative research frontier analysis methods and existed problems, it was pointed out that the automatic detection method of heterogeneous data source text mining was a trend for the research frontier identification methods.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the abnormal expression of plasma proteins by analysis of proteomic expression profile in children with infectious mononucleosis (IM).</p><p><b>METHODS</b>Two dimensional gel electrophoresis (2-DE) followed by the mass spectrometry was used to examine important protein spots with different expression levels between children with IM and normal controls.</p><p><b>RESULTS</b>Seven differential proteins were obtained: hemopexin, vitamin D binding protein, fetuin A, C-reactive protein, apolipoprotein A, haptoglobin and transthyretin. Compared with the control group, haptoglobin showed a higher expression level in children with IM, and the expression levels of the other proteins were obviously down-regulated.</p><p><b>CONCLUSIONS</b>The expression changes of differential proteins identified in this study are all related with the liver acute injury, suggesting that children with IM are associated with acute liver injury. Further studies on the characteristics of above proteins will contribute to the diagnosis and treatment of pediatric IM.</p>

Objective To explore hospice home care method of dying children.Methods In 58 cases of dying children at home were given personalized hospice care plan,then the questionnaire were adopted to investigate the related indexes and the results were analyzed.Results In home hospice care,parents had a high recognition and satisfaction to children's pain management and symptom care.The parents with different education background had significant difference in recognition extent of psychological support,games support and death education.The parents anxiety and depression mood got effective mitigation through hospice home care of dying children.Conclusions Implementation of personalized home hospice care can increase life quality of dying children and improve adverse mood of their parents.
ABSTRACT
BACKGROUND: Is the inhibition of the hematopoietic stem progenitor cell (HSPC) proliferation and differentiation after human cytomegalovirus (HCMV) infection associated with abnormal expression of infected cell proliferated gene?OBJECTIVE: To observe the HOXB6-mRNA expression in the process of proliferation and differentiation of HCMV-infected HSPC into colony-forming unit granulocyte-macrophage (CFU-GM) and colony-forming unit erythroid (CFU-E).DESIGN: A controlled observation.SETTING: Laboratory for Molecular Biology, Affiliated Hospital of Luzhou Medical College, Lanzhou, Gansu Province, China.MATERIALS: All cord blood (CB) specimens were provided by the Obstetrics Department of Affiliated Hospital of Luzhon Medical College. They were collected from the umbilical vein of normal term neonates delivered spontaneously. All neonate mothers were healthy and HBS-Ag-negative. HCMV-IgM antibody revealed by routine ELUSA and HCMV-DNA checked by PCR were undetectable. Written informed consent for the laboratory measurements was obtained from each neonate mother, and the protocol was approved by the hospital's Ethics Committee. HCMV-AD169 strains were obtained from the Institute of Virology, Chinese Academy of Preventive Medicine. All-trans retinoic acid (ATRA, lot No. 20010126) was provided by Chongqing Huapont Pharm. Co., Ltd., China.METHODS: This study was performed at the Laboratory of Molecular Biology (state-level), Affiliated Hospital of Luzhou Medical College of Luzhou Medical College from April 2006 to April 2007. Cord blood mononuclear cells were separated for HSPC culture. According to different interventions, the study consisted of 4 groups. Control group: no HCMV virus solution was added and equal volume of culture medium was added instead. HCMV group: 105 PFU/mL HCMV-AD169 virus solution was added to the culture system. ATRA group: ATRA was added into the cultivation system at the final concentration of 60 μ mol/L. HCMV+ATRA group: ATRA was added into the HCMV group, and its final concentration was also 60 μ mol/L.MAIN OUTCOME MEASURES: In each group, cells were harvested on days 3,7 and 12. HOXB6 mRNA expression levels in CFU-GM and CFU-E were detected by real-time fluorescent-based quantification PCR.RESULTS: In the control group, both CFU-E and CFU-GM expressed HOXB6-mRNA. The HOXB6 mRNA expression was increased as a function of time. The HOXB6-mRNA expressed by CFU-E reached its peak level on day 12, while that expressed by CFU-GM reached its peak level on day 7. Compared to control group, the expression levels of CFU-E and CFU-GM HOXB6-mRNA genes in normal cord blood were significantly lower in the HCMV group (P<0.05)and significantly higher in the ATRA group (P<0.05) at each time point after HCMV infection. Furthermore, the expression levels were significantly higher in the ATRA+HCMV group than in the HCMV group at each time point(P<0.05-0.01).CONCLUSION: HOXB6-mRNA expression is stable and lasting in the proliferation and differentiation of HSPC into CFU-GM and CFU-E. HCMV could down regulate HOXB6 gene expression, and ATRA could up regulate HOXB6 gene expression.
