AIM　To study the efffects and mechanisms of hetrazane（diethylcarbmazine citrate，DEC）on contraction of isolated tracheal strips of guinea pigs. METHODS　Using isolated tracheal strips technique. Each tracheal strip was placed in an organ bath filled with a Krebs solution of 37℃ and various drugs was added respectively. It was determined that KCl or 5-HT induced the contractile effects and its dose-response curve on tracheal strips and DEC or verapamil changed the effects of KCl or 5-HT. RESULTS　The contractions induced by KCl or 5-HT in isolated tracheal strips of guinea pig were markedly inhibited by DEC, the IC50 value of DEC for contraction induced by KCl and 5-HT was 5.03 mmol*L-1 and 9.54 mmol*L-1 respectively. DEC caused rightward displacement of the dose-response curse for KCl and 5-HT, and significantly depressed the maxmal response, showing anon-competitive antigonism, the pD′2 values were 1.554 and 1.851 respectively, and DEC markedly inhibited the contractions induced by Ca2+ released from an intracellular store and extracellular Ca2+. CONCLUSION　DEC can significantly inhibit contraction of tracheal strips induced by KCl and 5-HT, and its mechanism is responsible calcium-antagonistic effect of DEC.

Forty—five patients with irritable bowel syndrome and 52 normal controls were assessed with theCoping Style Questionnaire.Compared with controls,male patients scored lower in three subscales of Asscrtion,RationalProcessing,and Control,but higher in the the subscales of Support Orientation,Emotional Processing,and Resignation.The score of Emotional Processing in female patients was significantly higher than that im female controis.The data sug- gested that there was difference in coping between IBS patients and normal controls,and between the male and female pa-tients.

Objective To estimate the effect of Yiqi-Wenyang-Gujing decoction combined with the conventional western therapy on the elderly with chronic glomerulonephritis. Methods The 65 patients who conforming to the diagnostic criteria were randomly divided into the treatment group (33 patients) and control group (32 patients) according to the random number table. The control group was treated with the conventional western therapy, and the treatment group was treated with Yiqi-Wenyang-Gujing decoction based on the former treatment. After the treatment of 8 weeks, the curative effect of edema and the 24 hours urine protein and the changes of renal function were observed. Results Compare with the control group, the 24 hours urinary protein (0.8 ± 0.1 g vs. 1.3 ± 0.7 g, t=4.625), the SCr (132.0 ± 8.5μmol/L vs. 163.9 ± 6.2μmol/L, t=17.242) and the BUN (7.1 ± 2.2 mg/L vs. 9.2 ± 2.5 mg/L, t=3.598) of treatment group significantly decreased (P<0.01);The glomerular filtration rate of treatment group [(73.9 ± 4.2 ml/(min·1.73 m2) vs. 65.4 ± 2.4 ml/(min·1.73 m2), t=9.976] significantly increased (P<0.01). And the degree of edema was relieved more in the treatment group than that of the control group (P=0.049). The total effective rate of the treatment group was significantly better than that (78.8% vs. 46.9%, P=0.016) of the control group. Conclusion The combined Yiqi-Wenyang-Gujing decoction and western medicine treatment on the elderly with chronic glomerulonephritis could improve the kidney function and relieve edema.

With the thorough research on cognitive impairment in old age,vascular cognitive inpairment (VCI) has become a hot research field of neuroscience in recent years.Yet,the VCI-related pathogenic mechanism currently remains unknown.Therefore,the reliable and stable animal models are needed to reveal the pathogenesis and pathophysiologic changes of VCI in order to provide a theoretical basis for early warning,diagnosis and treatment of VCI.The commonly used animal models now have their own advantages and disadvantages,the results have greater differences.This article reviews the commonly used VCI animal models,related cognitive behavior changes,and change characteristics of histopathology in recent years,and the reasonable animal models of VCI according to different research objectives are investigated preliminarily.

BACKGROUND:Mesenchymal stem cells from transgenic animals carry green fluorescent protein that can be stably expressed in viable cells and can be used to rapidly screen modified cells in comparison with traditional virus and plasmids. OBJECTIVE:To study the biological features of bone marrow derived stromal cells from transgenic rats with green fluorescent protein gene. METHODS:Bone marrows were isolated from the bilateral long bones of 2-week-old transgenic rats with green fluorescent protein gene, and cultivated in conditioned culture medium to obtain bone marrow mesenchymal stem cells with green fluorescent protein gene. The passage 5 bone marrow mesenchymal stem cells with green fluorescent protein gene were analyzed by flow cytometry to detect cellsurface molecules, and were induced in calcium or adipogenic induction medium. After calcium induction, the alizarin red staining was performed to test the formation of calcium concentration. After adipogenic induction, bone marrow mesenchymal stem cells were detected with oil red O staining. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cells, stably expressing green fluorescent protein gene, were obtained successful y from the transgenic rat with green fluorescent protein gene. The cells expressed CD90, CD105 strongly, but did not express or weakly expressed CD14 andCD45. After 3 weeks of calcium induction, jacinth calcium salts could be detected in the cells by alizarin red staining. At 3 weeks of adipogenic induction, the cells showed positive oil red O staining. The green fluorescent protein gene, as report gene, exerts no effect on the cellsurface molecules and multilineage potential of bone marrow mesenchymal stem cells, which can be used as an efficient tracer.

In recent year, one of the hot topics in esophageal carcinoma research is the impaired gene expression resulted from hypermethylation within the promoter regions of rumor suppressor genes. Many studies suggested that DNA methylation plays an important role in the initiation, invasion, and metastasis of esophageal carcinoma. DNA methylation spectrum in peripheral blood may be used as markers for early diagnose, prognosis prediction and follow up in esophageal cancer patients. De-methylation of tumor suppressor genes may become a target of esophageal carcinoma therapy.
