Objective To investigate the influence of carbon monoxide(CO) on the content of atrial natriuretic peptide(ANP) in ventricular tissues of rats.Methods The left and right ventricular tissues of 12 Wistar rats were divided into control group(n=12) and hemin group(n=12,the final concentration of hemin was 10~(-4) mol/L),respectively.The ventricular tissues were successly incubated in(37 ℃) thermostatic waterbath with Krebs solution as supernatant for 4 hours.After incubation of the ventricular tissues,radio-immunity method was applied to determine the content of ANP in the supernatant.Results Compared with the content of ANP in the supernatant in control group,it was significantly decreased both in left [(9.72?3.59) vs(52.05?31.65) ng/(g?wet tissue),P

Objective: To evaluate the prevention and treatment effects of acupuncture-moxibustion for Alzheimer disease (AD) based on various AD mouse models.Methods: Several representative types of mouse models were selected according to the pathophysiological causes of AD, including senescence accelerated mouse/prone (SAMP) mice, soluble amyloid-β protein (Aβ) injection mice/rats, amyloid precursor protein (APP) transgenic mice, and APP/PS1 double transgenic mice. Through the observation of behavioral changes and analysis of core items, the possible mechanisms of acupuncture-moxibustion in preventing and treating AD were explored. Results: Acupuncture-moxibusiton therapy can improve AD mice's cognitive dysfunction; the major action mechanisms including increasing cerebral blood flow, improving the expressions of vital proteins in the hippocampus, preventing neuron cell apoptosis, promoting the clearance of Aβ deposition, activating autophagy pathway to reduce memory deficits and regulating the metabolisms of brain-derived neurotrophic factor, tyrosine kinase receptor B, N- acetylaspartate and glutamic acid. Conclusion: Although the optimal mouse model is not determined, it is sure that acupuncture-moxibustion therapy can improve cognitive function. A more suitable AD animal model should be duplicated in order to better explore the inherent action mechanism of acupuncture-moxibustion in preventing and treating AD.

Objective To discuss prevention and treatment of the late complications of deteniaceacal-colon continent urinary reservoir. Methods 105 patients who underwent detenia ceacal-colon con-tinent urinary reservoir were followed up for 9 -82 months(mean 40.5 months).Clinical data of these wereretrospectively analyzed. Results Late complications occurred in 25.7%(27/105) of the cases and 9were treated with operations,including difficulty with catheterization in 4 cases(3.8%),3 treated with dila-tion and 1 with efferent limb reconstruction with ileal,urinary pouch stones in 5(4.8%),4 treated with li-thotomy,urinary pouch perfotation in 1 (0.95%),treated with repair,urinary pouch superdistention in 1(0.95%),treated with reduction, single or double lateral hydronephrosis in 8(7.6%),caused by strictureof single or double lateral lower ureters in 4 (2 treated with excision lesion and anastomosis ) and by refluxin 1,1 case suffering from azotemia preoperatively worsened to uraemia treated with regular haemodialysis,hyperchloremia in 7 (6.7%),only 1 needed drugs treatment,repeated urinary infection in 11,amomg them,10 were complicated by the other complications,all treated with sensitive antibiotic. Conclusions Most ofpatients underwent detenia ceacal-colon continent urinary reservoir had good curative effects. Late complica-tions afflicting these patients mostly had immediate or mediate relations with symptomatic urinary infection.Prevention and treatment of symptomatic urinary infection can reduce the occurrence of late complications ofthis operative method,regular and adequant pouch washing and catheterization is efficient to prevention oflate complications of this operative method.

Objective:To study the social psychology of people when facing severe acute respiratory syndrome(SARS),a sudden social crisis.Methods:Using the social psychological methods,we analyzed the manifestations,causes and hazards of the public fear derived from the outbreak of SARS in China.Results:Sudden outbreak of SARS made people full of uncertainty and fear,and such fear would bring adverse effects to the society.It affected not only the daily life of people,but aslo their physical, mental stability and behavior reaction.Conclusion:SARS makes us realize the importance of psychology and psychiatry to individuals and to the society.It is imperative to establish a comprehensive provention and intervention system of diseases to maintain the social stability and the well being of individuals.

Objective To explore the effects of ligustrazine on secretion of nitric oxide(NO) in ventricular tissues of rats under physiologi-cal condition.Methods Twenty-four normal wistar rats were divided into three groups,eight each group.The left and right ventricular tissues of each rats were divided into control group and 2 ligustrazine groups and the final concentrations of ligustrazine were 15 mg/L and 150 mg/L respectively.The ventricular tissues that had been cutting into small pieces were incubated in 37 ℃ thermostatic water bath for 4 hours with Krebs solution as supernatant.After incubation of the ventricular tissues,the spectrophotometric method was used to detect the content of NO_2~-/NO_3~-in the supernatant.Results Compared with the content of NO in control group,it was significantly decreased in the 150 mg/L ligustrazine group(P

Hypertension is one of main risk factors for the occurrence and death of stroke and coronary heart disease. Its prevalence rate is rising year by year. It severely threatens the health of the human beings. The acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" for treating hypertension launched by Academician SHI Xue-min has aroused great attention due to good cur- ative effect and less adverse reactions. In this paper principles of the circular motion covered by the acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" were clarified.

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.
