Application of simplified strategy to diffuse long lesions in the elderly / 中国医师进修杂志

Objective To evaluate the clinical efficacy of the simplified strategy in the treatment of diffuse long lesions in the elderly. Methods Two hundred and forty patients over 75 years old with diffuse long coronary artery disease and successfully implanted stents were divided into two groups according to whether the stent placement was completed or limited. The clinical features, pathological features, percutaneous coronary intervention (PCI) status and long-term prognosis of the two groups were observed. The success rates of angiography and surgery were compared between the two groups. The medication was followed up. The major adverse cardiovascular events (MACE) and all-cause mortality were compared between the two groups at 1 year after surgery. Results There was no significant difference between the two groups in cardiac death [1.56% (2/128) vs. 1.87% (2/107)], non-lethal acute cardiac muscle infarction (AMI) [1.56% (2/128) vs. 2.80% (3/107)], all-cause death [4.69% (6/128) vs. 4.67%(5/107)], revascularization of target vessels [2.34%(3/128) vs. 5.61%(6/107)] and angina pectoris recurrence [4.69% (6/128) vs. 7.47% (8/107)], P > 0.05. The difference between the two groups was statistically significant only in the follow-up of coronary angiography [18.75%(24/128) vs. 8.41%(9/107)], P < 0.05. Conclusions The long diffuse coronary artery lesions in the elderly can be implanted with point stents by simplified strategy. The long-term clinical effect is generally satisfactory.

Relationship between QT interval(QT)and metabolic syndrome / 实用医学杂志

Objective To investigate correlation between QT interval(QT),corrected QT interval(QTc) and metabolic syndrome(MS). Methods Residents who participated in our survey concerning atherosclerosis and related diseases conducted in Shenyang were included. They accomplished questionnaire,physical examination, laboratory tests and electrocardiography test. We divided them into MS group and non-metabolic syndrome (NMS)group according to International Diabetes Federation(IDF)diagnostic criteria for MS. QT interval was measured from the standard 12-lead electrocardiogram. QTc was calculated by using Bazett and Fridericia equations. We analyze correlation of QT ,QTc and MS. Results A total of 739 residents who were 35~64 years old were included. Individuals with MS had longer QTcB and QTcF than NMS group[(415.8 ± 31.9)ms vs.(410.1 ± 32.1)ms, (407.2± 29.1)ms vs.(402.6 ± 28.8)ms,P<0.05]. The more the number of abnormal MS parameters they had, the longer the QT,QTcB and QTcF they had. Regression analysis showed that QT was associated with serum potassium,smoking,blood glucose,and LDL,and QTcB and QTcF were associated with hypertension,waist circumference and blood potassium. Conclusions MS is associated with corrected QTc. Careful ECG monitoring among persons with MS for early detection of a long corrected QT interval may prevent severe and often fatal arrhythmias or sudden death.

Objective By comparing the efficacy and complication rates of the 8-mm-tip cryoablation catheter with the normal electrode ablation catheter in the treatment of atrioventricular nodal reentrant tachycardia,this study investigated the efficacy and feasibility of ablation with the 8-mm-tip cryoablation catheter.Methods This is a retrospective case-control study including 122 patients with AVNRT treated with CRYO (n =56) using an 8-mm-tip cryoablation catheter or RF ablation (n =66) from June 2014 to May 2016.The procedure success rate,the recurrence rate,atrioventricular block incidence,procedure time and the difference between the X-ray fluoroscopy dose were compared between the 2 groups.Results The procedure success rate was comparable between the 2 groups(100％ for CRYO vs.98.5％ for RF,P ＞0.999)and no AVB was found in both groups.The CRYO group needed shorter procedural time [(66.29±4.72)min vs.(70.00 ± 7.50) min,P =0.001] and less X-ray exposure [(674.14 ± 126.12) mSv vs.(837.52 ± 138.38) mSv,P ＞ 0.001] than the RF group.Conclusions 8-mm-tip cryoablation catheter cryoablation for atrioventricular nodal reentrant tachycardia is as safe and effective as compared to conventional radiofrequency ablation with potential advantages.

Lateral lumbar interbody fusion for adult degenerative scoliosis: how to provide evidence supports / 中国组织工程研究

BACKGROUND: Most of evidence-based studies include both adult degenerative scoliosis and adult idiopathic scoliosis, which lead to indirectness in the results, and suppress the promotion of the evidence.OBJECTIVE: To systematically analyze the current clinical researches, and to review the curative efficacy of lateral lumbar interbody fusion for adult degenerative scoliosis.METHODS: A computer-based research of Medline, EMBASE, CENTRAL, WanFang and CNKI databases from December 2015 to December 2016, was performed with the key words of lateral lumbar interbody fusion, direct lumbar interbody fusion, extreme lateral interbody fusion, minimal invasive surgery, adult scoliosis. The articles were screened based on the inclusion criteria, and the clinical symptom improvement and radiological changes were analyzed.RESULTS AND CONCLUSION: Totally 13 articles were included. In the treatment of adult degenerative scoliosis, lateral lumbar interbody fusion shows less blood loss, short hospitalization time, significantly improved symptoms, satisfactory correction at the coronal plane, and low incidence of long-term complications. However, it has the poor correction at the sagittal plane and high incidence of short-term postoperative complications. Therefore, intraoperative neurologic monitoring is necessary and the combination with internal fixation has obtained good effectiveness.

Surgical techniques and clinical evidence of vertebroplasty and kyphoplasty for osteoporotic vertebral fractures

Osteoporotic vertebral fracture is a disease condition with high morbidity and mortality, whose prevalence rises with mean increase in the life span. Conventional treatments for an osteoporotic vertebral fracture include bed rest, pain medication and brace implementation, but if the patient's pain is severe, cement augmentation procedures, including vertebroplasty and kyphoplasty, are performed. Vertebroplasty and kyphoplasty are relatively easy procedures that have been reported to be effective in controlling acute pain. But, the risk of complication and additional adjacent segment fracture and their superiority over conventional treatment remain debatable. Therefore, the authors have summarized the procedures, complications, and clinical evidence of vertebroplasty and kyphoplasty in this review.

Effect of Chemotatic Factor FKN,PI3K and NF-κB on IL-6 Expression in Peripheral Blood Monocytes and the Effect of Valsartan Intervention / 中国医科大学学报

Objective To explore effect of irregular chemotatic factor fractalkine(FKN),phosphatidyl inositol 3 kinase and nuclear factor?κB(NF?κB)on interleukin?6(IL?6)expression in peripheral blood monocytes and the effect of valsartan intervention,so as to research the signal conduc?tive mechanism of FKN impacting on IL?6. Methods Peripheral blood monocytes were isolated from fresh blood of healthy volunteers by the densi?ty gradient centrifugation. The extractive peripheral blood monocytes were divided into seven groups:the control group,the FKN group,the LY294002 group(PI3K inhibitors),the PDTC group(NF?κB inhibitors),the FKN+valsartan group,the FKN+LY294002 group,and the FKN+PDTC group,the latter two were pretreated by LY294002 and PDTC respectively before FKN inducing PBMC cells. The IL?6 expression in cell me?dium was measured in each group by ELISA at 12 hours and 24 hours after PBMC treatment. Results After 12 hours of culture,compared with the control group,the expression of IL?6 in the FKN group was decreased(P0.05). Compared with the FKN group,the expression of IL?6 was decreased in the FKN+valsartan group(P0.05). Conclusion FKN can adjust the expression of peripheral blood PBMC IL?6 in a two?way pattern, inhibiting the expression of IL?6 by PI3K pathway and promoting the expression of IL?6 by NF?κB pathway,overall,FKN can inhibit the expression of IL?6. Valsartan can increase FKN to inhibit the expression of IL?6.

Discrepancy of Independent Risk Factors of Smoking Relapse in Different Age Patients after Percutaneous Coronary Intervention / 中国医科大学学报

Objective To study the independent risk factors of relapse of smoking among current smokers of different ages who underwent percuta?neous coronary intervention(PCI). Methods Totally 197 current smokers who received PCI from January 2007 to December 2009 in the Fourth Affiliated Hospital of China Medical University were enrolled. Information about relapse of smoking was collected through the medical records and the telephone follow?up. Discrepancy of risk factors of smoking resumption was compared in different age groups. Results Totally 112 patients re?sumed smoking after PCI. There were 87 patients in the non?elderly group and 25 in the elderly group. According to the correlation analysis,more than one stents(P=0.025),severe nicotine dependence(P=0.001)and long time for daily passive smoking(P=0.000)were related with relapse in the non?elderly group,and there was a negative correlation between more than one stents and relapse. But in the elderly group,relapse was associ?ated with history of hypertension(P=0.034). According to the logistic regression analysis in different age groups,independent predictors of smoking relapse in the non?elderly group were severe nicotine dependence(OR:3.914,P=0.003)and long time for daily passive smoking(OR:1.352,P=0.000). And in the elderly group,independent risk factors of smoking relapse were male(OR:17.325,P=0.027),history of hypertension(OR:13.185,P=0.005),long time for daily passive smoking(OR:1.273,P=0.045)Conclusion Independent risk factors of smoking relapse were different in the elderly group and the non?elderly group. In the non?elderly group,these factors were severe nicotine dependence and long time for dai?ly passive smoking. And in elderly group,these factors were male,history of hypertension,long time for daily passive smoking.

Comparison of ischemic heart disease incidence between left and right breast cancer treated with post-op radiation therapy / 中国医师杂志

Objective To compare the difference in ischemic heart disease (IHD) incidence between left and right breast cancer treated with post-op radiation therapy.Methods We retrospectively reviewed electronic database of breast cancer patients treated in our cancer center from October 2006 to December 2011.Clinical data were recorded including clinical features,radiation fraction,and IHD.Statistical analysis was performed to compare the difference in IHD incidence between left and right breast cancer.Results Age on diagnosis was significantly associated with IHD (P ＜ 0.05).Compare to younger patients (≤60),the increased hazard ratio of IHD in older patients (＞60) was 3.84.The left breast cancer patients had greater incidence of IHD with the increased hazard ratio of 1.57 although this difference did not reach statistical power (P ＞ 0.05).No patients got IHD in the intensity-modulated radiation therapy group.Conclusions Left-side breast cancer patients may have more probability to get IHD after thoracic radiation therapy compared to right-side patients.We recommend that left-side breast cancer patients should be treated with intensity-modulated radiation therapy to spare heart if they receive prophylactic radiation therapy after surgery.

Effect of hyperkalemic solution on atrial natriuretic peptide secretion / 中国综合临床

Objective To define the effect and mechanism of hyperkalemic solution on atrial natriuretic peptide (ANP) secretion in rabbits. Methods Eighteen rabbits were selected and the chest was opened under anes-thetization to remove the heart. The left atrium was isolated and fixed in the atrial perfusion system with proper electric stimulation for beating. The following experiments were carried out on beating rabbit atria: ①The atrium was perfused for 60 min to stabilize parameters of ANP secretion and atrial dynamics. The control period (12 min as an experimental cycle) was followed by an infusion of hyperkalemic solution (K+ concentration of hyperkalemic solution was 5.64 mmol/L and the osmolarity of hyperkalemic solution was unchanged) for three cycles, then normal K+ cancentration was recovered for two cycles;②The control period was followed by an infusion of L type Ca2+ channel blocker nifedipine (1.0 μmol/L) for three cycles;③L type Ca2+ channel inhibitor nifedipine (1.0 μmol/L) was infused for 36 rain prior (three cycles) to infusion of hyperkalemic solution. Atrial stroke volume was determined and the ANP secretion was measured by radioimmtmoaasay. Results (1)Hyperkalemic solution increased atrial ANP secretion (P<0.01) and reduced the atrial stroke volume,hut the difference was not statistically significant as compared with that of the control cycle(P>0.05). The recovery trend was to the normal level of ANP secretion and atrial stroke volume was to become normal gradually when solution level recovered to normal ,which was not significantly different from that of the control cycle (P>0.05) ;②Nifedipine (1.0 μmol/L) also increased the atrial ANP secretion (P<0.01 or P <0.05) while decreasing atrial stroke volume (P<0.01 or P < 0.05 ) ; ③Nifodipine (1.0μmol/L) completely blocked the effect of hyperkalemic solution so to increase the ANP secretion (P <0.01 ). Conclusion Hyperkalemic solution significantly increases atrial ANP secretion via extracellular high K+ competitive inhibition of extracellular Ca2+ inflow in beating rabbit atria.
