【目的】观察TNF-α对3T3-L1脂肪细胞葡萄糖转运蛋白4（GLUT4）mRNA与蛋白表达的作用,并探讨核因子-κB（NF-κB）对上述作用的影响。【方法】成熟的3T3-L1脂肪细胞分成3组：A组正常对照组,B组肿瘤坏死因子α（TNF-α）组,C组吡咯烷二硫基甲酸酯（NF-κB活性抑制剂）＋TNF-α组。各组干预48h后检测phospho-NF-κBp65（Ser536）的蛋白水平、GLUT4mRNA及蛋白水平。蛋白检测采用Western法,mRNA检测采用RT-PCR法。【结果】B组phospho-NF-κBp65蛋白水平（71.1±5.9）高于A组（41.3±1.7,P〈0.001）和C组（25.4±4.7,P〈0.001）。B组GLUT4的mRNA水平（0.86±0.14,P〈0.001）与蛋白水平（31.6±7.2,P〈0.001）低于A组（2.01±0.65;60.7±8.4）,C组mRNA水平（0.46±0.12）与B组比较有下降趋势但无统计学意义（P=0.100）,C组蛋白水平（9.5±3.0）低于B组（P=0.001）。【结论】TNF-α下调3T3-L1脂肪细胞的GLUT4表达,抑制NF-κB活性后GLUT4表达进一步下调。这提示了TNF-α可能不是通过激活NF-κB而使GLUT4的表达下调。     

抑制NF-κB对大鼠肾小球系膜细胞血管紧张素Ⅱ1型受体表达的影响

【目的】研究抑制NF-κB活性对SD大鼠系膜细胞血管紧张素Ⅱ1型受体mRNA表达的影响。【方法】分离SD大鼠系膜细胞分为下列3组：正常葡萄糖培养组（5.6mmol/L D-葡萄糖）,高葡萄糖培养组（25mmol/L）,吡咯烷二硫氨基甲酸酯（pyrrolidinedithiocarbamate,PDTC）＋高葡萄糖培养组。以电泳迁移率变动分析法（electrophoretic mobility shift assay,EMSA）检测NF-κB活性,RT-PCR方法检测血管紧张素Ⅱ1型受体mRNA表达,蛋白质印迹法（Western blot）检测血管紧张素Ⅱ1型受体蛋白表达,放射免疫分析法检测培养液血管紧张素Ⅱ水平。【结果】NF-κB活性在高葡萄糖培养组（20±7）显著高于正常葡萄糖培养组（8±4,P〈0.01）与PDTC＋高葡萄糖培养组（8±3,P〈0.01）,正常葡萄糖培养组与PDTC＋高葡萄糖培养组比较无显著性差异（P〉0.1）。血管紧张素Ⅱ1型受体mRNA表达,在高葡萄糖培养组（0.60±0.26）与正常葡萄糖培养组（0.50±0.22）及PDTC＋高葡萄糖培养组（0.45±0.23）均无显著性差异;血管紧张素Ⅱ1型受体蛋白质表达,在高葡萄糖培养组（0.54±0.22）与正常葡萄糖培养组（0.37±0.14）及PDTC＋高葡萄糖培养组（0.40±0.13）均无显著性差异。培养液血管紧张素Ⅱ水平在高葡萄糖培养组（9.8±2.1）显著高于正常葡萄糖培养组（7.5±1.5,P〈0.05）,PDTC＋高葡萄糖培养组（7.8±1.7,P〉0.05）与正常葡萄糖培养组比较差异无显著性意义。【结论】高葡萄糖可激活SD大鼠系膜细胞NF-κB,伴随血管紧张素Ⅱ产生增加,但是不影响血管紧张素Ⅱ1型受体表达;抑制NF-κB活性似乎可降低血管紧张素Ⅱ产生但不影响血管紧张素Ⅱ1型受体表达。

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.     

Insomnia Due to Deficiency of Both the Heart and Spleen Treated by Acupuncture-Moxibustion and Chinese Tuina

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.     

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.
