Objective To characterize the clinical presentation of noncardiac chest pain(NCCP), to investigate the quality of life among NCCP patients,and to understand the relation between NCCP and acid reflux and the value of proton pump inhibitor(PPI) in diagnosis of NCCP.Methods Eighty-seven NCCP patients were enrolled to the study.All patients received lansoprzole 30 mg twice daily for 7 days. Patients filled out a questionnaire survey before and after the PPI treatment.The questionnaire included the general personal data,the symptom scale,the medical outcome study 36-item short form healthy survey(SF-36),Zung Self Rating Anxiety Scale(SAS) and Zung Self-rating Depression Scale(SDS).The results were analyzed in comparisons of healthy control group.Results①The most common cause for NCCP was gastroesophageal reflux disease (GERD).The typical reflux syndrome presented among 34.5% of the patients.②Among 87 patients,acid-related NCCP was accounted for 56.3% (49/87), whereas non-acid-related NCCP was accounted for 43.7% (38/87).The sensitivity and specificity of PPI test were 91% and 81%,respectively.③Except the role of role emotional(RE),7 healthy conceptions in the health-related quality of life in NCCP patients were significantly lower than those in healthy volun- teers(P

Objective To assess the clinical safety and effectiveness of Boomerang closure device (Boomerang Percutaneous Femoral Access Management System) applied to patients undergoing coronary angiography (CAG) and/or percutaneous coronary intervention (PCI).Methods206 patients undergoing CAG and/or PCI were randomly divided into the heparin group and low molecular heparin (LWMH) group. The hemostasia success rate, hemostasia time, manual pressure time, device dwell time, complication rate and time to ambulation with each other of two groups were compared.ResultsThe heparin group and LWMH group both had high hemostasia success rate (98.06% and 99.03%), there wasn't significant difference between two groups. There was one patient with hematoma formation in the heparin group and LWMH group respectively. There was no significant difference between two groups in hemostasia time, manual pressure time, the device dwell time and time to ambulation.ConclusionAfter CAG and/or PCI, administered heparin and low molecular heparin is no effect on Boomerang closure device, and Boomerang closure device has a high hemostasia success rate.

Objective To assesse the quality of life of patients after cardiac pacemaker implantation using the Chinese version of SF-36.Methods Ninety-eight patients with permanent cardiac pacemaker implantation were investigated before and after the operation in terms of quality of life by using the Chinese version SF-36.Results Successful surgery was performed on all the 98 patients.The previous symptoms of the patients were improved to vari- ous extend after the operation.The quality of life of the patients was significantly improved after operation as demon- strated by the significant difference of the scores in 9 domains of SF-36 when compared with those before the operation (P

Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.

This thesis is about a new technology of program-controlled telemetry for pacemakers. The system utilizes digital logic circuit design, and the program-controlled part uses single chip to control for display and debug. PWM and reflectance telemetry may improve the preciseness and correctness of signal transmission, and reduce the power consumption of pacemakers and prolong the lifetime.

Objective To perspectively evaluate the long-term efficacy of low dose leflunomide in treatment of rheumatoid arthritis.Methods Twenty-eight patients with rheumatoid arthritis were randomly divided into treatment group( n =15 ) and control group ( n =13 ).The patients in treatment group were treated with low dose leflunomide( omitting the loading dose) and with maintenance dose of 10 mg/day.And the patients in control group were treated with sulphasalazine in the dose of 1.5 ～ 2.0 g/d.The observation lasted for 18 months and the observed indicator were as follows:( 1 ) The primary efficacy indicators:counts of swollen and tender joints,overall assessment of disease status made by patients and physicians; ( 2 ) Secondary efficacy indicators:pain visual analogue scale,duration of morning stiffness,health assessment questionnaire (HAQ),Creaction protein,the American College of Rheumatology Outcome Assessment (ACR20,50).Results Eighteen months after treatment,the primary efficacy indicators in the treatment group were superior to the control group ( swollen joint counts:( - 8.5 ± 6.3 ) vs ( - 7.9 ± 6.4) ; overall assessment by patients:( - 1.4 ± 0.8 ) points vs ( - 1.2 ± 0.6) points; overall assessment by physicians:( - 1.4 ± 1.2 ) points vs ( - 1.3 ± 0.9 ) points; P ＜0.01 ).In the secondary efficacy indicators,pain visual analogue scale,duration of morning stiffness and health assessment questionnaire(HAQ) in the treatment group were significantly improved compared with the control group(VAS score:( - 32.4 ± 23.7) points vs ( - 31.6 ± 24.8) points; duration of morning stiffness:( [ - 97.8 ± 6.2 ] min vs [ - 92.4 ± 5.2 ] min; HAQ:[ - 0.62 ± 0.08 ] points vs [ - 0.57 ± 0.02 ] points,P ＜0.01 ),there was no significant difference on the percentage of patients achieving ACR20 standard between the treatment group and the control group (76.9％ vs 75.0％,P ＞ 0.05 ),but there was significant difference on the percentage of patients achieving ACRS0 standard between the treatment group and the control group( 61.5％ vs 47.0％,P ＜ 0.05 ).The gastrointestinaladverse reactions for patients in the treatment group were mild and there were 2 cases of elevated blood pressure,2 cases of elevated liver enzymes and 2 cases out of the trail,in the control group,there was 1 case out of the trial.Conclusion The long-term treatment of active rheumatoid arthritis with low dose leflunomide can achieve exact efficacy and good tolerability compared with the treatment with sulfasalasine.
