Objective To assess the effectiveness and safety of different dual antiplatelet therapies in patients undergoing percutaneous coronary intervention. Methods Such databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched to collect the randomized controlled trials (RCTs) and observational studies on the effectiveness and safety of dual antiplatelet therapies both short-duration (≤6 months) and long-duration (gt;6 months) after percutaneous coronary intervention. The literature was screened according to the inclusive and exclusive criteria by two reviewers independently, the quality was evaluated, the data were extracted, and meta-analyses were performed by using RevMan 5.1 software. Results Eight trials were included, of which 3 were RCTs involving 7 475 patients, and 5 were observational studies involving 12 744 patients. Meta-analyses on RCTs showed that the incidence of death or myocardial infarction in the long-duration treatment group was lower than that of the short-duration treatment group (OR=0.74, 95%CI 0.56 to 0.98, Plt;0.000 1), while meta-analyses on observation studies showed the similar result (OR=0.7, 95%CI 0.45 to 1.08, P=0.11). With the variables of published year and follow-up time, the heterogeneity of cohort studies was discussed through meta-regression (Z=3.61, P=0.000) which indicated that both published year and follow-up time might be the source of heterogeneity due to their contribution. For RCTs, the incidence of severe bleeding events in the short-duration treatment group was lower than that in the long-duration treatment group (OR=1.29, 95%CI 0.99 to 1.69, P=0.06). For observational studies, the incidence of late stent thrombosis in the long-duration treatment group was lower than that in the short-duration treatment group (OR=0.40, 95%CI 0.15 to 1.07, P=0.07). Conclusion The long duration (gt;6months) of dual antiplatelet therapy in patients undergoing percutaneous coronary intervention can reduce the incidence of death or myocardial infarction and decrease the tendency of late stent thrombosis, but cannot obviously increase the incidence rate of severe bleeding events. The current evidence shows no marked superiority in longer duration (gt;12months) of dual antiplatelet therapy.
ObjectiveTo explore the effect of programmed family nursing intervention on medication compliance in hypertensive patients. MethodsA total of 160 patients with hypertension treated between August 2012 and July 2013 in our hospital were chosen to be our study subjects. They were randomly divided into two groups:control group (n=80) and trial group (n=80). Patients in the control group were given routine nursing intervention for six months, while those in the trial group received six-month programmed family nursing intervention. Then, we compared the effect of blood pressure control and medication compliance between the two groups. ResultsThe effect of blood pressure control and medication compliance in the trial group after the intervention was better than that in the control group, and the difference was statistically significant (P<0.05). ConclusionThe programmed family nursing intervention is better than the routine nursing intervention in terms of effect of blood pressure control and patients' medication compliance, and it is an effective nursing method for hypertensive patients.
Objective To summarize the experience of emergency coronary artery bypass grafting （CABG） after failed percutaneous coronary intervention. Methods From January 1998 to December 2002, 9 patients underwent emergency CABG after failed percutaneous coronary intervention. The indications of emergency CABG were coronary artery dissection （5 cases）or perforation （2 cases） and acute arterial occlusion （2 cases）. The time averaged 2 hours from onset of ischernia to revascularization. The CABG was performed under off-pump bypass in 3 cases and under CPB in 6 cases. The mean graft number was 3. Results There were no hospital death. The mean follow-up was 17 months. No death and angina occurred. The function of New York Heart Association class Ⅰ-Ⅱ were in 8 patients, class Ⅲ in 1 patient. Conclusion Emergency CABG is an effective management for failed percutaneous coronary intervention if the indication is right.
ObjectiveTo assess the causes and risk factors of multiple-intervention in endovascular aortic repair (EVAR) for type B aortic dissection (TBAD). MethodsWe retrospectively analyzed the clinical data of 347 TBAD patients initially treated with EVAR in our hospital between January 1999 and December 2013. The patients were stratified into a multiple-intervention group (34 patients) and a single-intervention group (313 patients). We analyzed the differences of clinical data of the two groups. ResultsThere were 9 patients with endoleak, 10 patients with new dissection, 8 patients with incomplete thrombosis of the false lumen, 4 patients with new aneurysm, 2 patients with retrograde dissection, and 1 patient with iliac artery occlusion in the multiple-intervention group. Higher proportions of chronic dissection and smoking occurred in the multiple-intervention group (79.4% versus 50.8%, 61.8% versus 40.3%, P=0.002, 0.018, respectively). Both of the degree and proportion of hyperglycemia were higher in the multiple-intervention group (6.9±2.3 mmol/L versus 5.7±1.8 mmol/L, P=0.027; 44.1% versus 22.7%, P=0.011). There were statistical differences in oversizing rate of grafts (14.6%±3.2% versus 11.3%±2.5%, P<0.001), operation time (172 min versus 82 min, P<0.001), and blood loss (280 ml versus 100 ml, P=0.006) between the two groups. ConclusionEndoleak, new dissection, and incomplete thrombosis of the false lumen are the main causes of multiple-intervention. While in chronic phase, smoking, hyperglycemia, too big oversizing, and complicated lesion or operation are the potential risk factors.
With the development of interventional therapy technology, trans radial access (TRA) has gradually become the main approach of interventional therapy. Compared with trans femoral access (TFA), TRA has obvious advantages, which can shorten the time of lying in bed and reduce the incidence of complications. However, the radial artery is thinner than the femoral artery, the incidence of spasm is high, and the success rate of puncture is low, so the technical level of operation is required to be high. Nowadays, TRA has been gradually applied to lung cancer, aortic disease, hepatocellular carcinoma, spleen disease, renal artery disease, and other peripheral vascular diseases. With the confirmation of the safety and feasibility of TRA in interventional therapy in different fields, the popularization of TRA in different interventional fields will be supported.
ObjectiveTo observe the effect of bundle interventions on ventilator-associated pneumonia (VAP) in Intensive Care Unit (ICU). MethodsBaseline survey among the patients undergoing mechanical ventilation was conducted during June 2011 to August 2011. During September 2011 to May 2012, the rate of VAP was monitored every three months after taking bundle measures, which included oral care, elevation of the head of the bed, daily assessment of readiness to extubation, optimizing process of devices disinfection and hand hygiene. ResultsThrough carrying out the bundle interventions, the VAP rate decreased from 61.2‰ to 34.9‰ after six months and 22.7‰ after nine months, and the ventilator utilization ratio decreased from 26.5% to 24.6% after six months and 22.6% after nine months. The alcohol-based hand disinfectant dosage was increased from 32.6 mL to 58.8 mL and 54.4 mL for each patient bed in ICU. ConclusionThe bundle intervention has been proved to be effective. Measures such as staff education, bedside supervision and monitoring data feedback can help implement bundle interventions.

Spinal cord injuries (SCI) seriously impair the quality of life, functional status, and social independence of the patients. Since the last century, a series of basic research on spinal cord injury has made us a deep understanding of its mechanisms and pathophysiology. But so far, how to repair damaged nerve functions after SCI is still a neurological problem. There are still controversies surrounding some treatment strategies for SCI, including the use of magnetic resonance imaging, type and timing of anticoagulant prevention, the timing of surgical intervention, the use of corticosteroids such as methylprednisolone sodium, as well as the type and timing of rehabilitation. For patients with SCI, early surgical intervention and neuroprotective therapy may be the best treatment. At the same time, rehabilitation and psychological intervention are equally important.
ObjectiveTo evaluate the safety and efficacy of microwave ablation (MWA) in the treatment of lung tumors.MethodsThe clinical data of 31 patients with lung neoplasms treated with MWA from January 2019 to August 2020 in a single center were retrospectively analyzed. There were 17 males and 14 females at an age of 63.4±10.4 years. The characteristics of the lesions, technical success rate, technical efficiency, local progression rate, adverse reactions and complications were recorded in detail.ResultsThere were 39 target lesions with an average diameter of 20.2±10.6 mm. A total of 36 MWA procedures were completed. The initial technical success rate was 84.6% (33/39), and the technical efficiency was 92.3% (36/39). The median postprocedure hospital stay was 2.0 (2.0, 3.0) d. A total of 12.9% (4/31) of the patients had local progression, and the local control rate was 87.1%. The main adverse reactions were pain (12/36, 33.3%), cough (6/36, 16.7%), post-ablation syndrome (6/36, 16.7%) and pleural effusion (3/36, 8.3%). The main complications were pneumothorax (11/36, 30.6%), hemorrhage (8/36, 22.2%), cavitation (2/36, 5.6%) and pulmonary infection (1/36, 2.8%). The median follow-up time was 13.0 (8.0, 18.0) months. No patient died during the follow-up.ConclusionMWA is safe and effective in the treatment of lung tumors with controllable complications. Successive researches with large sample, and medium and long-term follow-ups are needed to explore the significance of combined therapies.
