目的:探讨高脂高能量饮食诱导下肥胖易感(obesity-prone,OP)大鼠与肥胖抗性(obesity-resistance,OR)大鼠腹膜后脂肪组织中脂联素基因mRNA表达的差异。方法:18只雄性SD大鼠,以高脂高能量鼠料饲养2周后,按体重增值大小分组,增重最多6只为OP组,增重最少6只为OR组。OP、OR大鼠继续饲以高脂高能量鼠料4周后,观察各大鼠体重变化和腹膜后脂肪组织湿重,并采用RT-PCR技术检测脂肪组织中脂联素基因的mRNA表达水平。结果:①高脂高能量鼠料诱导下,OP组大鼠体重、腹膜后脂肪组织湿重均明显高于OR组(P<0.01);②OP组大鼠腹膜后脂肪组织中脂联素基因的mRNA表达水平显著低于OR组(P<0.05);③大鼠腹膜后脂肪组织湿重与脂联素基因mRNA的表达水平间存在显著的负相关关系(P<0.05)。结论:相同饮食条件下,个体发生肥胖的易感性是影响脂联素水平的重要因素。     

高脂饮食诱导下肥胖易感大鼠与肥胖抗性大鼠间部分生理学指标差异的研究

目的：探讨高脂饮食诱导下肥胖易感(OP)大鼠肥胖抗性(OR)大鼠在体重、食量、Lee’s指数、脂肪湿重、血脂及脂肪组织脂蛋白脂酶(LPL)基因表达等方面的生理学差异。方法：48只SD大鼠，以高脂饲料饲养1周后，按体重增值从大到小百分排序，取第75百分位以上为OP组，第25百分位以下为OR组，继续高脂饲养4周；观察各大鼠体重变化、摄食量、Lee’s指数、脂肪湿重、血脂等，采用Northern Blot分析脂肪组织中LPL基因的mRNA表达水平。结果：①OP大鼠的体重增值、热能摄入、Lee’s指数及腹腔脂肪湿重均显著高于OR大鼠，但血脂水平两组间无差异；②高脂饲养1周、5周时OP大鼠体重增值分别是OR大鼠的6．54、4．25倍，热能摄入仅为OR大鼠的1．13、1．15倍；③OP大鼠脂肪组织中LPL基因的mRNA表达水平显著高于OR大鼠。结论：OP与OR大鼠间存在生理学差异，其原因除OP大鼠热能摄入较多因素外，0P大鼠体内较高的能量效能是其肥胖易感性较高的重要因素，而能量效能与脂肪组织LPL基因的表达水平可能存在密切关系。

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.     

Qiu Baoguo''''s Experience in Treating Consumptive Syndromes after Radio-Chemotherapies

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.     

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.
