Objective To explore the correlation between wide QRS of transesophageal atrial pacing (TEAP) and implicit ventricular pre-excitation.Methods 77 patients tested by TEAP were divided into two groups according to the ECG results .45 patients in group Ⅰhad normal electrocardiogram .32 patients in group Ⅱhad ven-tricular pre-excitation.In group Ⅰ,TEAP results showed that electric pulse wave (S wave) was followed by intermit-tent or continuous wide QRS complex .At the same time , the results of group Ⅰ were compared with the results of groupⅡ.Results (1)The patients of group Ⅰwere excluded the presence of concealed accessory pathway by intra-cavitary electrocardiographic test,among them 20 patients (group ⅠA) were ventricular pacing,the test results dis-played that S wave was followed by wide QRS complex exhibiting a pattern of right bundle branch block ( RBBB) ,SR interval was 0 s;SR intervals of 25 patients (groupⅠB) were not fixed,SR interval was (0.07 ±0.01)s,S wave had no concern with QRS wave ,the wide QRS complex was premature ventricular contraction ,QRS wave shapes were dif-ferent according to the different sites of pacing origin .(2)In groupⅡ,the test results displayed that S wave was close-ly followed by the atrial depolarization wave P ,and there was a wide QRS complex with pre-excitation wave at the be-ginning after a atrioventricular conduction time shorter than normal ,SR interval was fixed ,SR interval was (0.08 ±0. 03)s,at the same time,different parts of accessory pathway QRS complex had different morphological characteristics . (3) SR interval of ⅠA group compared with groupⅠB and groupⅡ,the differences were statistically significant ( t=2.97,3.02,all P<0.05);SR interval had no statistically significant difference between group ⅠB and groupⅡ(t=2.66,P>0.05).Conclusion When TEAP displaying pacing wide QRS complex ,in order to avoid bringing misdiag-nosis,TEAP results should be analyzed comprehensively rather than blindly believing that the reason was concealed accessory pathway .

Objective To evaluate the diagnostic significance of ECG and coronary arteriography (CAG) in coronary heart disease in different age groups. Methods totally 216 cases of suspected or CAG-confirmed coronary heart disease were retrospectively analyzed. The non-elderly group included patients aged 45-59 years, and the elderly one was older than 60. Patients in each group were further divided into subgroup A and B with or without the pain in heart front area, respectively, accompanied by ST-T change in ECG. Comparative analysis of CAG and ECG changes was done between different age groups, and between subgroup A and B. The history of pain in heart front area, serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), platelet count (PLT), and fibrinogen (Fg) were also analyzed for clinical diagnosis. Results In the non-elderly, positive CAG was 88.8% in subgroup A while 56.3% in group B ( P0.05). TC, LDL-C, and Fg were significantly higher in subgroup A than in subgroup B for the elderly group. But in non-elderly, TC, TG, LDL-C, and Fg in subgroup A were significantly higher than those in subgroup B(all P0.05). The history of pain in heart front area was longer in the elderly, and also in this age group, more patients showed multivessel involvement. Conclusions ST-T change of ECG accompanied by classical pain in heart front area is more valuable than single ST-T change in the diagnosis of coronary heart disease, especially among non-elderly patients. ST-T change could not be used simply as a tool to diagnose coronary heart disease. The diagnosis should be made generally considering the typical symptom of the pain in heart front area, clinical history, TC, TG, LDL-C, and Fg. CAG could increase the positive diagnostic rate of coronary heart disease and decrease the rate of misdiagnosis as well.

Objective To evaluate the efficacy and adverse effect of valproic acid (VPA) in combination with low dose chemotherapy on intermediate and high-risk myelodysplastic syndrome. Methods A total of 41 patients with intermediate (34) and high-risk (7) myelodysplastic syndrome were retrospectively analyzed. Among them, 19 patients received low dose chemotherapy regimen and 22 received low dose chemotherapy plus VPA.Low dose chemotherapy regimen included: homoharringtonine,1-2 mg·m-2·d-1 intravenously,14-28 d; clarubicin,5-7 mg·m-2·-1 intravenously,1-8 d,15-23 d;cytarabine 15 mg/m2 subcutaneously once every 12 h, 14-21 d; and subcutaneously use of granulocyte colony-stimulating factor 200 μg·m-2·d -1 when neutrophil deficiency.The outcome and adverse effect were recorded after the treatment. Results The overall response rate in the low dose chemotherapy regimen group was 47.4% (9/19), 6 patients (31.6%) achieved complete response (CR). The overall response rate in the VPA group was 77.2% (17/22), 9 patients (40.9%) achieved CR. The overall response rate of the low dose chemotherapy in combination with VPA group was significantly higher than that in the low dose chemotherapy group (P＜0.05) while no difference was found in CR rate. The adverse effect of the low dose chemotherapy in combination with VPA regimen was tolerated. Conclusion With acceptable adverse effect, the low dose chemotherapy in combination with VPA regimen is effective for the treatment of intermediate and high-risk myelodysplastic syndrome. Long-term outcome needs further investigation.

Objective To evaluate the bone healing effect of vascularized tissue-engineered bone induced by endothelial progenitor cells(EPCs)in repair of large segmental radius defects in rabbits.Methods A total of 68 healthy New Zealand white rabbits were enrolled in the study and randomized into three groups,ie,experimental group(EPCs group):EPCs plus bone marrow mesenchymal stem cells (BMSCs)plus decalcified bone matrix(DBM);control group:BMSCs plus DBM;sham control group:pure DBM.Materials mentioned above were implanted into middle radius defects for 15 mm.At 12 and 16 weeks post-operatively,X-ray test,bone mineral density test,histological light microscopic test,osteocalcin immunohistochemical staining test and biomechanical test were carried out.Results Growth and plasticity of callus,speed of medullary cavity recanalization,bone healing speed and biomechanical intensity in the experimental group were all significantly better than those of control group.Conclusions Vascularized tissue-engineered bone induced by EPCs has strong osteegenic ability,can accelerate bone healing and hence is an effective method for repair of large segmental bone defects.

Objective To discuss the application value and improvement of principle of multi-echelon medical care in emergent rescue of the injured in Chinese Wenchuau earthquake. Methods The author analyzed and evaluated the medical rescue that was done at disaster site, in the front line hospital and higher level hospitals during earthquake. Results A total of 4 689 patients were treated at disaster site, including 413 patients with severe injury, of whom 3 died. Different kinds of operations including debridement were performed at disaster site, with infection incidence of open wound was nearly 80%. In the front hne hospital, 1 400 patients were treated, with 200 operations done. Of all, 110 patients with severe trauma were treated emergenfly, with an amputation rate of 3.0% and postoperative infection incidence of 66.8%. In the station hospitals, 125 patients received definite surgeries, with 1-5 surgeries per injury site. There was no postoperative cross infection, amputation or death. Conclusions The multi-echelon medical care is the basic mode for medical rescue of large number of patients in natural disaster rescue. First aid at disaster site should be performed as early as possible. Transportation is crucial for successful rescue and an improved patient grading system can help increase the efficiency of rescue. The front line hospitals should mainly provide life support, debridement and fixation of simple fracture, while the specific treatment and definite surgery should be carried out in the station hospitals.

Since the introduction of laparo-endoscopic single-site surgery(LESS) in China in 2008, this technique has developed rapidly in the domestic urology field. This paper systematically reviews and summarizes the historical process of the development of single-site laparoscopy technique in domestic urology. From the exploration period, the rapid development period, the rational thinking period to the current breakthrough development period, the technology has made great progress in related theoretical foundations, surgical operation skills, device development and clinical norms. It has many advantages such as less postoperative pain, minor damage in body surface, and rapid recovery. But the limitations including narrow operating space and great instrument interference are still remain. At present, the development of domestic single-site laparoscopy technique is generally stable and standardized. The robotic single-site surgery system may be able to effectively solve the problem of instrument interference, but the clinical advantages and application value of the robotic single-site surgery system still need to be further clarified by prospective, multi-center, large sample and high-quality clinical research.

Objective To explore the intervention effect of TCM constitution health education on constitution and relevant health indicators.Methods The research design was adopted with nocontrol group before and after the test evaluation.A total of 595 subjects were recruited.Interventions of emotion,diet,sleeping and living,exercise,and meridian and acupoint massage were concluded in the TCM constitution health education interventions.Investigated their constitution,health related quality of life(MOSSF-36)and laboratory indexes before and after the intervention of 3 months and 6 months. Results 509 subjects were available.After 3 months intervention,the score of gentleness type was sig-nificantly increased by 3.67 points (P<0.05)while scores of pathological constitutions except yang-de-ficiency type were significantly decreased (P<0.05).All of the absolute values of standardized response mean (SRM)ranged from 0.10 to 0.5 1 .After 6 months intervention,the score of gentleness type was significantly increased by 3.67 points (P<0.05)while scores of all pathological constitutions were sig-nificantly decreased (P<0.05).All of the absolute values of SRMranged from 0.23 to 0.75.Physical component summary (PCS )scores and mental component summary (MCS )scores of MOS SF-36 were significantly increased (P<0.05 )after 3 months and 6 months intervention.After 3 months interven-tion,systolic pressure (SP),diastolic pressure (DP),2-hour postprandial glucose (2hPG),and total cholesterol (TC)decreased significantly (P<0.05),but high density lipoprotein-cholesterol (HDL-C) was significantly increased (P<0.05 ).After 6 months intervention,SP,DP,2hPG,TC,triglyceride (TG)and low density lipoprotein-cholesterol (LDL-C)were significantly decreased (P<0.05 ),but HDL-Cwassignificantlyincreased(P<0.05).Conclusion TCMconstitutionHealtheducationinter-vention can improve the constitutional conditions,clinical abnormal indexes,and the quality of life resul-ting in the improvement of health.However,the intervention effects were generally low,which indicates that the constitution is relatively stable.Therefore,a long-term of TCM constitution intervention is neces-sary for health promotion.
