目的 探讨三羟异黄酮(genistein, GEN)对辐射损伤造血功能的影响.方法 6.0 Gy γ射线一次全身照射BALB/c雄性小鼠复制出造血损伤模型.照射前24 h给予GEN灌胃(160 mg/kg体质量),分别观察照射后1、3、7、14、21、30 d不同时相点小鼠血清对粒单系集落形成单位(colony-forming unit-granulocyte/macrophage, CFU-GM)和红系集落形成单位(colony forming unit-erythroid, CFU-E)的支持或抑制活性.结果 辐射前24 h给予GEN,辐射后该组小鼠血清造血刺激活性显著增加,使正常小鼠骨髓有核细胞CFU-GM、CFU-E形成数量明显增多,而且对CFU-GM的刺激活性较CFU-E强.同时,该组小鼠照后血清对CFU-GM、CFU-E的抑制活性明显降低,但对CFU-E和CFU-GM的抑制活性差异不明显.结论 提高辐射损伤后小鼠血清刺激活性可能是GEN防护放射性造血损伤、促进受损造血系统重建的分子机制之一.     

川芎嗪对辐射致血虚证小鼠骨髓细胞蛋白质表达的影响

目的:观察川芎嗪对辐射致血虚证小鼠骨髓细胞蛋白质表达的影响,探讨川芎嗪补血作用的分子机制。方法:采用3.5 Gy60Coγ射线全身1次性照射,制备小鼠血虚证模型;骨髓集落细胞培养,观察并计数粒系-巨噬细胞集落生成单位(CFU-GM)、爆增型红细胞集落生成单位(BFU-E)、红细胞集落生成单位(CFU-E)、混合集落生成单位(CFU-mix)集落数;利用蛋白质组学寻找差异表达蛋白质。结果:辐射后小鼠骨髓CFU-GM、BFU-E、CFU-E、CFU-mix集落数明显减少,川芎嗪能使其显著回升并部分逆转辐射后蛋白质表达的变化,使小鼠骨髓细胞5种蛋白质表达回升,5种回落。结论:川芎嗪可促进辐射致血虚证小鼠骨髓造血祖细胞增殖,调节多种骨髓细胞蛋白质的表达,后者可能是川芎嗪促进造血细胞生长和增殖的重要机制之一。

目的利用FOXO3A基因敲除小鼠探讨FOXO3A在造血系统电离辐射(ionizing radiation,IR)损伤中的影响。方法 FOXO3A~(-/-)小鼠和WT小鼠(FVB/N)分为野生型小鼠对照组(WT组),FOXO3A~(-/-)小鼠对照组(FOXO3A~(-/-)组),野生型小鼠照射组(WT+IR),FOXO3A~(-/-)小鼠照射组(FOXO3A~(-/-)+IR)四组,分别接受假照射和4 Gy X射线全身照射(total body irradiation,TBI),剂量率为0.9 Gy/min。接受TBI后14 d检测FOXO3A~(-/-)小鼠和WT小鼠脏器指数、外周血和骨髓细胞计数,骨髓细胞分型,造血祖细胞(HPCs)粒细胞巨噬细胞集落形成单位(colony forming unit-granulocyte and macrophage,CFU-GM)形成能力,观察FOXO3A基因敲除对造血系统辐射损伤的影响。结果生理情况下,FOXO3A~(-/-)小鼠骨髓有核细胞计数下降,HPCs比例升高(P0.05);小鼠接受4 Gy X射线TBI后14 d,FOXO3A基因敲除会加重电离辐射诱导的HPCs和造血干细胞(HSCs)比例下降,但也会抑制辐射诱导的骨髓有核细胞数下降和造血祖细胞CFU-GM形成能力减退。结论 FOXO3A基因敲除破坏造血系统稳态维持,加重TBI小鼠HPCs和HSCs的辐射损伤,对造血细胞辐射敏感性产生一定的影响。FOXO3A在造血系统电离辐射损伤中的调节作用以及能否作为防治损伤的靶点还有待进一步研究。

Acupuncture Treatment of Vomiting

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.

Analysis of CK-19,PDX-1,Nestin,Ngn3 in different donor islet purity in rats

Objective: To investigate if there are the CK-19, PDX-1, Nestin, Ngn3 positive cells in the donor islets of different purity in rats. Methods: Thirty male adult SD rats were randomly divided into 3 groups. Islets were isolated using digestion by ductal injection of collagenase. Group Ⅰ (n=10): Separating cell preparations were not purified, Group Ⅱ(n=10): Islet sediment was purified with 25% Ficoll400 ,Group Ⅲ (n=10): Islet sediment was purified with 25% and 11% Ficoll-400. The levels of protein of CK-19, PDX-1, Nestin and Ngn3 were detected by immunohistochemistry and the mRNA of CK-19, PDX-1, Nestin, Ngn3 was amplified by RT-PCR. Results: After two different purification methods applied, three islet preparations of different purities were obtained. The difference of islet purity was significant among various groups (P＜0.05). Compared with group Ⅱ and group Ⅲ,the protein and mRNA of CK-19, PDX-1, Nestin,Ngn3 were both higher in group Ⅰ; group Ⅲ was poorly expressed. Conclusions: The three different islet purity donor islet have different CK-19, PDX-1, Nestin, Ngn3 positive cells within them, indicating that there are some islet stem cells in the purified donor islet.     

A preliminary screening study on the associated proteins in human psoriasis vulgaris by serum proteomics technologies

Objective：To investigate the optimum screening conditions of associated proteins in human psoriasis vulgaris by serum proteomics technique, and to screen the different expression proteins related with psoriasis vulgaris. Methods：Serum samples of peripheral blood were collected from newly diagnosed psoriasis vulgaris patients in the clinic, and 20 matched healthy persons. Serum albumin IgG was removed by filtering with ProteoExtract Albumin/IgG. After comparative proteomics analysis the different protein spots were identified using 2-DE and MS. Results ：Electrophoresis figures with high resolution and reproducibility were obtained. Three different expression proteins were found only in the serum from psoriasis vulgaris patients, while nine other different proteins expressing from healthy volunteers. Conclusion：The protein expression was different in the serum between the psoriasis vulgaris patients and healthy volunteers. It was hoped that we could find the biomarkers related to psoriasis vulgaris by using proteomics.
