Study on Village Working Team in Promoting the Development of Rural Medical and Health Services in Xinjiang from the Perspective of Healthy China / 中国医学伦理学

From the perspective of healthy China,the development of rural medical and health services in Xin-jiang still exists some problems,such as inadequate measures to implement rural medical and health services,un-reasonable allocation of rural medical and health resources and insufficient funds to develop rural medical and health services.Based on the analysis of main reasons,this paper put forward the important measures for imple-menting health poverty alleviation by village working teams in Xinjiang: implementing the important concept of" health poverty alleviation and precision poverty alleviation" ; improving the comprehensive quality of rural medical and health personnel; broadening funding channels of rural medical and health care; carrying out medical services to benefit the people and strengthening the assistance of rural medical and health services.

Autologous peripheral blood stem cell mobilization following dose-adjusted cyclophosphamide, doxorubicin, vincristine, and prednisolone chemotherapy alone or in combination with rituximab in treating high-risk non-Hodgkin's lymphoma / 癌症

<p><b>BACKGROUND</b>The regimen of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is an efficient treatment of non-Hodgkin's lymphoma (NHL). This study aimed to assess the efficacy and toxicity of dose-adjusted CHOP alone or in combination with rituximab (R-CHOP) by examining the stem cell mobilization in NHL patients. Factors affecting the collection of CD34+ cells were also explored.</p><p><b>METHODS</b>Our retrospective study included 39 patients eligible for autologous stem cell transplantation: 14 patients who expressed CD20 and were financially eligible received R-CHOP for autologous peripheral blood stem cell (APBSC) mobilization; the remaining 25 patients received CHOP.</p><p><b>RESULTS</b>The median CD34+ cell yield was 7.01×10(6) cells/kg body weight (range 1.49-28.39×10(6) cells/kg body weight), with only two patients failing to meet the target CD34+ cell harvest of ≥2.0×10(6) cells/kg body weight. The median number of apheresis procedures per patient was 1 (range 1-3). The APBSC mobilization yield of the CHOP group appeared to be higher than that of the R-CHOP group (P=0.005), whereas the success rate was similar between groups. R-CHOP elevated the complete response (CR) rate in B cell lymphoma patients as compared with CHOP (P=0.01). No significant differences in toxicity or engraftment were observed between the two groups.</p><p><b>CONCLUSION</b>The present study demonstrated that dose-adjusted CHOP chemotherapy effectively mobilized APBSCs in NHL patients and that the addition of rituximab to dose-adjusted CHOP chemotherapy elevated the CR rate for patients with B-cell lymphoma.</p>

Detection of growth phenotype and blood biochemical parameters of wild type-derived chromosome 1 substitution mouse strain / 中国实验动物学报

Objective To analyze the growth phenotype and blood biochemical parameters of chromosome 1 substi-tution mouse strain(CSS1), and investigate their potential of QTL mapping .Methods Body weight, body length, tail length, organ weight of the CCS1 mice were measured at different days to create a growth curve while blood biochemical in -dexes were measured at about the 80th day.Results The CCS1 mice were different from C57BL/6 mice in several inde-xes.Compared with the C57BL/6 mice during different developmental stages , six strains including B6-Chr1KM mice were significantly different in body weight .There were five strains including B6-Chr1CM mice significantly different with C57BL/6 mice in body length, and all of the CSS1 mice were significantly different from C57BL/6 mice in tail length.Part of CCS1 mice were significantly different from C57BL/6 mice in the weight of liver, spleen, kidney and brain.The ALT of female B6-Chr1CM mice was significantly higher than that in the C 57BL/6 mice.The ALP of female B6-Chr1HZ mice was signifi-cantly higher than that in the male C57BL/6 and B6-Chr1KM mice, and was significantly lower than that in the C57BL/6 mice.The TB of male B6-Chr1CM, B6-Chr1SMX and B6-Chr1HZ mice was significantly higher than that of the C 57BL/6 mice.The TG of male B6-Chr1SMX mice and male B6-Chr1TW mice was significantly higher than that in the C 57BL/6 mice. Conclusions The phenotype of Chr1 CSS mice is quite different from commonly used inbred strain C 57BL/6 mice.CCS1 mice show great potential in QTL mapping for their characteristic growth phenotype and blood biochemical indexes .

Bioinformatics analysis of mice Agouti gene polymorphism / 中国实验动物学报

Purpose Polymorphisms of candidate gene Agouti was analyzed in order to reveal the molecular mech -anisms of coat color difference in chromosome engineering mice .Methods Firstly, differences of mouse coat color was detected by color measurement spectrophotometer .Then, candidate gene Agouti was found by whole genome scanning based on DNA chip.Finally, cDNA and amino acid sequence polymorphisms were analyzed , as well as the influence of protein properties and function after mutation was predicted by bioinformatics software .Results There are five SNPs in the Agou-ti cDNA sequences , resulting in three missense mutations in the amino acid sequence of Agouti signaling protein .Bioinfor-matics analysis revealed that one βsheet deletion in the secondary structure of the mutant protein , as well as tertiary struc-ture changed , leading to decrease of binding ability .Conclusion A novel missense mutation is found in candidate Agouti gene.It plays critical role in receptor binding activity , and may reflect on mice coat color changing from light gray to dark gray eventually .
