Objective To evaluate the efficacy and safety of prostaglandin E1 (PGE1) for diabetic peripheral neuropathy (DPN). Methods We searched the Cochrane Library, PubMed, EMbase, CNKI, VIP and handsearched Chinese Journal of Metabolism, Chinese Journal of Diabetes and New Chinese Medicine. Randomized controlled trials of clinical therapeutic studies on PGE1 for DPN were included. The quality of included studies was evaluated and Meta-analysis was performed. Results Thirty-one trials involving 2 497 participants were included. Meta-analysis indicated that PGE1 was more effective than Vitamin B, Placebo and other microcirculation improving drugs in improving symptoms and signs of DPN. The RR (95%CI) were ［RR=1.75, 95％CI (1.54, 2.00)］, ［RRpooled=1.57, 95％CI (1.42, 1.74)］and［RR=1.31, 95％CI (1.19, 1.45)］respectively. PGE1 was more effective than Vitamin B, Placebo and other microcirculation improving drugs in improving nerve conduction velocity (NCV) of DPN patients. For spontaneous pain and hypesthesia of DPN patients, Lipo-PGE1 was more effective compared with PGE1-CD and the RR (95%CI) was［RR=1.43, 95％CI (1.16, 1.76)］. Slight adverse effects were reported in 16 studies. Conclusion Based on this review, PGE1 is effective for DPN. However, the evidence is not b enough due to the low quality of included trials. Further large-sample and multi-center studies are needed.
Objective To investigate the surgical treatment and results of coronary malperfusion due to acute Stanford A aortic dissection. Methods The clinical data of 56 patients with coronary malperfusion due to type A aortic dissection, who were hospitalized and underwent operation between January 2009 and December 2016, were analyzed retrospectively. There were 39 males and 17 females at age of 26–73 (51.36±16.47) years. Results The right coronary artery was involved in 48 patients, the left in 5 patients, and both coronary arteries in 3 patients. There were 12 patients with coronary bypass grafting, 19 patients with Cabrol’s operation, 25 patients coronary artery plasty. Twelve patients died postoperatively at mortality of 21.4%. Forty-four patients survived. The patients were followed up for 3 months to 3 years. No adverse event of cardiovascular happened. Conclusion Stanford A aortic dissection with coronary involvement is associated with high mortality rate.Aggressive coronary revascularization is essential to salvage these critically ill patients. The method to reconstruct the involved coronary depends on the patients’ condition and experience of surgeon.
Objective To explore the treatment experience of acute type-A aortic dissection with lower limb malperfusion. Methods From December 2012 to December 2016, 39 patients were diagnosed as acute type-A aortic dissection complicated with lower limb malperfusion and underwent operation.There were 27 males and 12 females with an average age of 51.4±12.4 years. Results Early mortality rate was 17.9%(7/39). 32 patients of postoperative survival. The follow-up rate was 93.8%(30/32), 3 months to 3 years after the operation, the results is satisfactory. The over lower limb malperfusion recovery rate of follow-up patients was 96.7%(29/30). Conclusion Positive operation for acute type-A aortic dissection with lower limb malperfusion is safe, feasible and effective.Concomitant or secondary bypass procedures are also possible to restore distal perfusion when necessary.Comprehensive evaluation of patient’s status is strongly recommended for optimal surgical decision making.
ObjectiveTo evaluate the results of a hybrid procedure for treating Stanford type B1C aortic dissection.MethodsIn our center, 49 patients with Stanford type B1C aortic dissection underwent supra-arch branch vessel bypass and thoracic endovascular aortic repair (TEVAR) from December 2013 to December 2017. There were 33 males and 16 females with an average age of 60.4±5.5 years. Left common carotid artery to left subclavian artery bypass (n=29), right common carotid artery to left common carotid artery and left subclavian artery bypass (n=18), left common carotid artery to left subclavian artery and right common carotid artery to right subclavian artery bypass (n=2) were performed.ResultsEarly mortality rate was 2.0% (1/49). Forty-eight patients survived postoperatively. The follow-up rate was 100.0% (48/48). The patients were followed up for 6 to 47 (26.8±11.9) months postoperatively. Chest pain relapsed in one patient 8 months after the operation. The whole aorta CTA showed type A1S aortic dissection in one patient 6 months after the operation, and the re-operation was satisfactory. There was no endoleak or paraplegia.ConclusionInitial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for type B1C aortic dissection.
ObjectivesTo evaluate the reporting quality of clinical practice guidelines published in Chinese journals in 2017.MethodsCBM, CNKI and WanFang Data databases were searched for articles published in 2017. Two reviewers independently screened literature, extracted data, and evaluated the reporting quality of clinical practice guidelines using the Reporting Items for Practice Guidelines in Healthcare (RIGHT).ResultsOne hundred and seven clinical practice guidelines were included and a total reporting rate of 34.8%±0.1% in RIGHT. Among the seven domains of RIGHT, field on basic information had the highest reporting rate (56.8%) and fields on review and quality assurance had the lowest reporting rate (9.3%).The average reporting rate of RIGHT items of Chinese Science Citation Database (CSCD) articles was lower than non-CSCD [MD=−0.73, 95%CI (−0.78, −0.68)] articles. The average reporting rates of RIGHT items differed between Chinese Medical Association (CMA) journal articles and non-CMA journal articles [MD=2.30, 95%CI (2.26, 2.34)]. The average reporting rates of RIGHT items was lower in guidelines established by associations or institutes [MD=−3.78, 95%CI (−3.83, −3.73)], and was higher reported in Chinese medicine guidelines [MD=21.94, 95%CI (21.91, 21.97)].ConclusionsThe reporting quality of clinical practice guidelines published in journals of mainland China in 2017 is low in general, especially in fields such as review and quality assurance, funding and declaration and management of interests and other information. To improve this phenomena, it is suggested that guideline developers report the guidelines rigorously with international standard.
ObjectiveTo investigate the application of ascending aorta cannulation and brachiocephalic trunk cannulation in acute type A aortic dissection.MethodsWe screened 183 patients with acute type A aortic dissection from January 2017 to January 2020 in our hospital. They were divided into 2 groups according to the cannulation strategy: ascending aorta cannulation and brachiocephalic trunk cannulation (a DAC group, n=42, 33 males and 9 females with a median age of 50 years) and the single axillary artery cannulation (an AAC group, n=141, 116 males and 25 females with a median age of 51 years). The general clinical data, intraoperative data and early postoperative results of the two groups before and after matching with propensity scores were compared.ResultsBefore propensity-score matching, the operation time, cardiopulmonary bypass time, aortic occlusion time and ICU stay in the DAC group were all shorter than those in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications, renal failure and pulmonary complications in the DAC group were significantly lower than those in the AAC group. After propensity-score matching, the operation time in the DAC group was significantly shorter than that in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications and pulmonary complications in the DAC group were significantly lower than those in the AAC group.ConclusionAscending aorta cannulation and brachiocephalic trunk cannulation can provide a safe, fast and effective method of establishing cardiopulmonary bypass for some acute type A aortic dissection patients, and significantly shorten the operation time without increasing surgical complications.
ObjectiveTo summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy.MethodFive patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years.ResultAll operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good.ConclusionThe short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.
