Objective To study the relationship between hyperhomocysteic acid(HHcy) and artherosclerosis.Methods 20 male rabbits were randomly divided into control and experiment groups(n=10).HHcy models were made by hypodermical injection of DL-methionine for 7 weeks.After 7 weeks homocysteic acid(Hcy),IL-1?,IL-6,and IL-8 in serum of rabbits in two groups were measured by enzyme linked immunosorbent assay(ELISA).And the pathomorphological changes of aorta were observed with HE staining.The number of NF-?B positive cells in the aorta were counted by immunohistochemical method.Results The levels of Hcy,IL-1?,IL-6 and IL-8 in experiment group were higher than those in control group(P

Objective To understand the awareness rate of pulmonary tuberculosis(TB) prevention and control among residents in Beijing, so as to provide basis for giving publicity on knowledge of pulmonary tuberculosis prevention and control.Methods Residents in Beijing were randomly selected for questionnaire survey, the main content of questionnaire included The 2006 national survey on knowledge, attitudes and practice about tuberculosis prevention and control, the core knowledge of pulmonary TB prevention and control, as well as the related symptoms of suspected tuberculosis were also included.Results A total of 520 questionnaires were collected, 503 of which were qualified, the effective rate was 96.73%.Among respondents, the total awareness rate of five core knowledge about pulmonary TB prevention and control was 40.87%, 78.93% of the respondents knew that pulmonary TB was a chronic respiratory infectious disease which could seriously damage people's health,48.51% knew that the majority of patients with pulmonary TB could be cured as long as they persisted in correct treatment, only 19.68% knew that examination and treatment of pulmonary TB in the county (district) level TB control institutions could enjoyed national free policy.Nearly 53.48% of respondents knew 4 or more suspected pulmonary TB symptoms, only 7.36% of respondents could recognize all eight symptoms of pulmonary TB.Conclusion Residents in Beijing have low awareness of pulmonary TB prevention and control knowledge.If patients in the early stage of pulmonary TB can not identify symptoms, it is not only delay treatment and increase the spread of tuberculosis, but also induce the transmission of multidrug-resistant Mycobacterium tuberculosis, so produce more challenges to pulmonary TB prevention and control.

Objective To study the activity of hepatitis B virus and therapeutic efficacy of adefovir in chron-ic hepatitis B patients with colon cancer during operation period. Methods 50 chronic hepatitis B patients with co-lon cancer to be underwent colon resection were divided two groups at random, one group was given adcfovir (adefovir group), the other group not (control group), and therapeutic measure except antivirus is the same. HBV-DNA con-centration and liver functon of the patients were detected. Results Serum HBV-DNA concentration and ALT level of the patients was increased significantly at 1 week and 1 month after operation compared with that before operation in control group. Serum HBV-DNA concentration of the patients was decreased significantly at 1 week and 1 month after operation compared with that before operation in adefovir group. The ALT level of patients in adefovir group is signifi-cantly lower than that in control group. Conclusions Surgical procedure may result in HBV replication and antivirus treatment should be done perioperatively. Adefovir can inhibite replication of HBV and also improve the liver function of the chronic hepatitis B patients with colon cancer during operation.

Immune cells that undergo increased apoptosis include lymphocytes and macrophages,yet the apoptosis of neutrophils is decreased in sepsis.Increase in apoptosis has also been reported in non-immune cells such as gastrointestinal cells,epithelial cells of lung as well as endothelial cells.The altered apoptotic cell death may contribute to the initiation and aggravation of immune and organ dysfunction in sepsis.Elucidating the changes and mechanism of apoptosis and taking measures to control apoptosis may be an effective strategy for the treatment of sepsis.

Objective To observe the therapeutic effect of Shen Wu Guanxin Granules(SWGG),a prescription with the actions of tonifying kidney,strengthening Qi and activating blood,for angina pectoris(AP) due to coronary heart disease(CHD) with kidney deficiency and blood stasis.Methods Ninety patients with AP due to CHD with kidney deficiency and blood stasis were randomized into two groups according to the double-blind and double-dummy principles.The two groups received routine western medicine,and the treatment group(N=60) received SWGG and the control group(N=30) received Di'ao Xinxuekang Capsules additionally.The treatment lasted 4 weeks.After treatment,the therapeutic effect on AP and electrocardiogram(ECG) was evaluated,and the changes of main symptoms as well as the laboratory parameters were observed before and after treatment.Results In the treatment group,the total therapeutic effect on AP and ECG was 91.7% and 85.0% respectively,higher than 73.3% and 66.7% in the control group(P

AIM: To evaluate the effects of glycemic control on refraction in diabetic patients. METHODS: Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose, HbA1c levels, fasting C-peptide and postprandial 2h C-peptide were measured before treatment. The patients with random blood glucose higher than 12.0mmol/L and HbA1c level higher than 10.0% were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1, 2, 3 and 4 during glycemic control.RESULTS: A transient hyperopic change occurred in all the patients receiving glycemic control. The maximum hyperopic change was 1.60D (range 0.50±3.20D). Recovery of the previous refraction occurred between two and four weeks after insulin treatment. There was a positive correlation between the maximum hyperopic changes and the HbA1c levels on admission (r=0.84, P<0.05). There was a positive correlation between the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment (r=0.53, P<0.05). During transient hyperopia, no significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length.CONCLUSION: Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of the blood glucose level.

A simple,reliable RPHPLC method on ODS column with UV detector for deter-mination of the anticoagulant rodenticide coumatetralyl in animal tissue was developed.1,1′-Bi-(2-Naphthol)was used as an internal standard to check the process ofexperiments.The mean recoveries from the spiked rabbit liver were around 90% atthe levels of 0.4-16mg/kg.The coeffecint of variation of 5 determination was 3.2%.The results showed that this method has a satisfactory reproducibility.The methodis practical for examining poisons in poisoning cases.

Nine Rabbits were orally administrated with a single dose of 25mg/kg,100mg/kgcoumatetralyl to establish poisoning model.Poisoning sympton and pathological changes were observed.Coumatetralyl content in main internal organsand muscle was determined by RPHPLC method.The results were discussed.

Objective:To explore effect for isoproterenol rising detection rate of paroxysmal supraventricular tachy‐cardia by transesophageal atrial pacing (TEAP) .Methods :A total of 85 patients with suspected PSVT attack history received routine TEAP ( basic stimulate ) ,for those failed to evoke PSVT ,they received additional intravenous infusion of isoproterenol to make heart rate rise to 120 beats/min ,then TEAP was repeated .Results :Routine TEAP evoked PSVT in 29 cases (34.1% ,29/85) ;among the remaining 56 cases un - evoked PSVT ,after intravenous infusion of isoproterenol PSVT was evoked in 54 cases (96.4% ,54/56) by TEAP ,and this detection rate was significantly higher than that of routine TEAP (96.4% vs .34.1% , P = 0.039) .Conclusion :Intravenous infusion of isoproterenol can greatly raise the detection rate of paroxysmal supraventricular tachycardia by transesophageal atrial pacing .
