Objective To provide evidence-based therapeutic schedule for an adult patient with Lumber Isthmic Spondylolisthesis grading II. Methods Based on fully assessing the patient’s conditions, the clinical problems were put forward according to PICO principles. Such database as The Cochrane Library (2005 to April 2011), DARE (April 2011), CENTRAL (April 2011), MEDLINE (April 2011), EMbase and CBM were searched to collect high quality clinical evidence, and then we told a patient information about treatment plans. The plan was chosen by the patient for she knew her conditions and the plans. Results We included 1 meta-analysis, 3 randomized controlled trials, 5 systematic reviews and 1 prospective study on the natural course of isthmic spondylolisthesis were included. Literature evidence indicated that the prognosis of isthmic spondylolisthesis was good. Surgery should be selected when there was neither no remission of symptom, nor progression of lumber olisthy with conservative treatment. The long-term effect of surgery may be good, but it cannot change the natural course of the disease. Based on literature evidence, the patient chose the conservative treatment. After one year’s treatment the patient recovered, her sciatica relieved, and CT showed no progression of lumber olisthy. Conclusion Patient with low grand isthmic spondylolisthesis chose conservative treatment may achieves good effects, whereas on the process of the treatment, regular follow-up to monitor the progression of lumber olisthy should be conducted.
ObjectiveTo summarize our experience of surgical treatment for right pulmonary artery originated from the ascending aorta by using adult diameter artificial vascular and study the operative indication, design, method, and therapeutic efficacy. MethodsWe retrospectively analyzed clinical data of 11 patients with right pulmonary artery originated from ascending aorta in The Second Affiliated Hospital of Harbin Medical University from May 2008 through December 2013, who were treated by using adult diameter artificial vascular. The patients ranged from 4 months to 25 months old, weighted 4-15 kg. Among of them, 4 patients had persistent truncus arteriosus and 7 had aortopulmonary septal defect. All patients were complicated with moderate pulmonary hypertension. All the patients underwent one stage surgical repair under extracorporeal circulation and cardiac arrest. During the surgery, end to side anastomosis was done between the right pulmonary artery and 16-18 mm diameter artificial blood vessels. And artificial blood vessel was connected to the main pulmonary artery or right ventricle outflow tract incision from the aorta above. ResultsThe average operation time was 179-325 (224±68) min. The average cardiopulmonary bypass (CPB) time was 81-208 (117±54) min. The average aortic clamping time was 29-63(42±21) min. The mean residence time in ICU was 71-197 (109±42) hours. The average assisted mechanical ventilator time was 59-191 (91±26) hours. The average length of stay in hospital was 21-39 (28±11) days. Low cardiac output syndromes caused by pulmonary arterial hypertension occurred in 5 patients including 2 deaths and 3 patients with good recovery by reducing the pulmonary arterial pressure and peritoneal dialysis. The result of postoperative cardiac color ultrasound examination of 9 survival patients showed vascular prosthesis, no distortion, no stenosis of the anastomosis, deformity correction satisfaction. Nine patients were followed up for 3-60 months. The results of echocardiography showed no anastomosis and artificial vascular stenosis, and the pulmonary arterial pressure decreased significantly. ConclusionThe right pulmonary artery originated from the ascending aorta in children should be operated as soon as possible. Compared the adult diameter artificial vascular treatment for one stage repair of right pulmonary artery from the ascending aorta with other operation methods, both short-term and long-term effects are good. Postoperative low cardiac output syndrome is a common complication.
Objective To formulate an individualized evidence-based treatment for a first-diagnosed patient with coronary artery-pulmonary artery fistula. Methods Aiming at the issue of whether interventional operation was necessary for first-diagnosed coronary artery-pulmonary artery fistula or not, the computer retrieval was conducted in the US National Guideline Clearinghouse, The Cochrane Library, PubMed and MEDLINE from 1990 to 2011, to collect and assess the best evidence of relevant systematic reviews, randomized controlled trials, controlled clinical trials and treatment guidelines, in order to be applied in clinical treatment. Results There were 1 clinical guideline for treating coronary artery fistula and 3 different high-quality evidence studies were retrieved. The results showed percutaneous coronary intervention was the best treatment currently. According to the obtained evidence and patient’s willingness, the relevant examinations were taken, and the preoperative preparation for percutaneous coronary intervention was done actively after the patient was admitted. Three days after hospitalization, the selective coronary angiography showed right coronary artery-pulmonary artery fistula and left coronary circumflexus artery-left atrial multiple fistulae, then the percutaneous coronary intervention spring coil embolization was successfully conducted for right coronary artery-pulmonary artery fistula. After operation, bayasprin enteric-coated tablets 0.1 g/d was taken for anti-platelet aggregation and preventing thrombotic diseases. The observation during operation and postoperative 5-day hospitalization showed no relevant complications. Conclusion Percutaneous coronary intervention is safe and effective for the symptomatic patients with coronary artery-pulmonary artery fistula.
Objective To report the screening, prevention and treatment of venous thrombosis for Lushan earthquake victims in the West China Hospital of Sichuan University. Methods Among the Lushan earthquake victims screened by vascular color Doppler, those with detected venous thrombosis were treated reasonably, and those without detected venous thrombosis were prevented early. Results There were total 235 Lushan earthquake victims in the hospital as of the 11th day after earthquake, and they were screened by vascular color Doppler. Among 26 cases with detected venous thrombosis, 25 were lower limb venous thrombosis, and the other one was upper limb venous thrombosis. Three cases were treated by rehabilitation intervention alone, three cases were treated by drug intervention alone, and the other 20 cases were treated by both rehabilitation and drug intervention. As of 30 days after the earthquake, the reexamination results of 26 victims with venous thrombosis showed that: 11 cases improved, including 5 completely recanalization and 6 incompletely recanalization. Among the three cases with drug intervention alone, one got completely recanalization, accounted for 33.33%. Among the three cases with rehabilitation intervention alone, one got incompletely recanalization, accounted for 33.33%. Among the 20 cases with both rehabilitation and drug intervention, four got completely recanalization, accounted for 20.0%, and five got incompletely recanalization, accounted for 25.0%. Conclusion Most Lushan earthquake victims with venous thrombosis are the elderly and women, stay in the ICU, and suffer from fractures in different degrees. The timely prevention and treatment can relieve local pain, promote early entry in the rehabilitation treatment, and prevent pulmonary embolism and other risks. The rehabilitation intervention and/or drug intervention should be adopted to the victims with detected venous thrombosis as well as the victims without detected venous thrombosis but have high risk factors, for it can effectively prevent and treat the further thrombosis and other bad consequences of the detachment of thrombus.
Objective To establish the evidence-based treatment strategy for an advanced lung cancer case with spinal metastasis, regarding the patient’s condition and treatment expectations. Methods According to PICO principles, questions in the patient’s treatment were converted into a search strategy. The literature searching was performed in several databases. In accordance with the five evidence grading standards in evidence-based medicine, the best clinical evidence was interpreted to guide the treatment decisions. Results A total of 148 papers were detected and screened, of which 4 systematic reviews or meta-analyses were included finally. Four issues that patients concerned, including restoring spinal cord function (walking and sphincter function), local pain control, long-term survival, and treatment complications, were all supported by grade-1 evidence. The patient finally chose surgical decompression, which was of a higher complication risk, but better possibility of restoring nerve function, significant pain relief, and improved long-term survival. The patient obtained fully recovery and regained walking function after surgery. Conclusion The evidence-based treatment is able to provide reasonable treatment options for lung cancer patients with spinal metastasis. Decompression surgery for patients with walking dysfunction should be carried out as soon as possible, in order to early restore spinal marrow function, relieve pain and improve long-term survival. But both doctors and patients should fully acquaint themselves with the higher risk of surgical complications.
H7N9, a novel avian influenza A virus that causes human infections emerged in February, 2013 in Anhui and Shanghai, China. The epidemic quickly spread to Zhejiang, Jiangsu and other neighbor provinces. As of May 30th, 2013, WHO had reported 132 cases, 37 (28%) of which died. Aiming at such serious outbreak of epidemic, we retrospectively analyzed its etiology, epidemiology, clinical characteristics, treatment, prevention and control based on data and evidence. Experience and evidence of the risk surveillance and management of such a novel anthropozoonosis lacks in China, or even lacks around the world. Quick and accurate identification of the rules and of the variation and transmission of avian influenza virus becomes a key to prevention, control and treatment. According to current best available evidence around the world, Chinese medicine and biomedicine should be put in to parallel use. Only realizing evidence-based decision making can we effectively prevent and control the epidemic, treat patients, and reduce the loss.
Objective To assess the efficacy and safety of hyperbaric oxygen treatment for patients with post-stroke depression. Methods Randomized controlled trials (RCTs) about hyperbaric oxygen treatment with placebo or open control in patients with post-stroke depression were comprehensively retrieved in PubMed (1966 to 2012.12), EMbase (1974 to 2012.12), EBSCO (1965 to 2012.12), CENTRAL (2012.11), CBM (1978 to 2012.12), CNKI (1980 to 2012.12), and VIP (1989 to 2012.12). References of the included articles were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the quality of the included studies. Then, meta-analysis was performed using RevMan 5.0. Results Twelve trials involving 822 patients were included, all of which were randomized non-placebo controlled trials. The results of meta-analysis of 12 trials (n=822) showed, the improvement of depression symptoms in the HBO group was better than that in the control group (MD=4.82, 95%CI 3.12 to 6.52). However, funnel plot showed that publication bias was large. After removing three trials for sensitive analysis, the results showed that the improvement of depression symptoms in the HBO group was still better than that in the control group (MD=3.91, 95%CI 3.35 to 4.47). Adverse events were reported in 2 trials, including dizziness, palpitation, mild earache, tinnitus, etc. However, no severe adverse events occurred. Conclusion Current evidence indicates that, HBO can effectively reduce the score of HAMD and no serious adverse reactions occurred. It’s necessary to further carry out high quality randomized controlled trials with large sample size due to limited quality and quantity of the included studies, so as to assess its effectiveness and safety.
Objective To review published literature on telemedicine in China using qualitative analysis. Methods Such databases as CBM, VIP, CNKI, and CSSCI were electronically and comprehensively searched for clinical studies related to telemedicine from inception to March 2013. References of the included studies were also retrieved. Two reviewers independently identified the literature according to inclusion and exclusion criteria, extracted data, and assessed the quality of the included studies. Then, qualitative analysis was performed in aspects of the application fields, range, and effects of the included studies. Result Finally, 19 studies were eligible for the analysis, including 16 quasi-randomized controlled trials and 3 observational studies. According to methodological evaluation standards (JBI, 2005), among 16 quasi-randomized controlled trials, 12 were of medium quality and four were of low quality; and 3 observational studies were all of low quality. The results of qualitative analysis showed that, literature on telemedicine had increased by year since 1995. However, the literature on relevant research of telemedicine had been published since 2002. The number of literature increased evenly and sporadically in journals. According to the classification of the application fields of telemedicine, 15 (80%) related to remote monitoring, especially related to remote fetal monitoring, 4 (21%) were remote consultation, and 3 (16%) were remote treatment. The results of 19 studies showed that, telemedicine had better effects than traditional medicine. Conclusion In China, literature related to telemedicine increases by year but the quality of them are low. High quality studies are further needed. The distribution of the application fields of telemedicine is uneven, most of which focuses on remote monitoring. The quality of research is low and need high-quality research in future. The therapeutic effects of telemedicine are better with accurate monitoring data and convenience to patients..
Objective To evaluate the effectiveness of topical fluoride on prevention of enamel demineralization during the orthodontic treatment in China. Methods The Cochrane Library（Issue 9, 2012), MEDLINE (1996 to 2012.10), EMbase (1974 to 2012.10), CNKI (1994 to 2012.10), VIP (1994 to 2012.10), WanFang data (1998 to 2012.10) and CBM (1978 to 2012.10) are searched for the randomized controlled trials (RCTs) and quasi-Randomized controlled trials (qRCTs) about topical fluoride preventing enamel demineralization during the orthodontic treatment. The bibliographies of the included studies were searched, too. Two reviewers evaluated the quality of the included studies and extracted data critically and independently, and then the extracted data were analyzed using RevMan 5.2 software. Results A total of 20 studies within 19 articles were included, which involved 26 323 teeth. The results of meta-analysis results show that, the rate of enamel demineralization of the fluoride varnish group (8.4%) was lower than that of the control group (16.0%) (OR=0.44, 95%CI 0.33 to 0.59, Plt;0.000 01); the rate of enamel demineralization of the fluoride coating group (8.3%) was lower than that of the control group (17.7%) (OR=0.46, 95%CI 0.35 to 0.60, Plt;0.000 01); the rate of enamel demineralization of the fluoride toothpaste group (9.0%) was lower than that of the control group (14.5%) (OR=0.59, 95%CI 0.49 to 0.71, Plt;0.000 01); the rate of enamel demineralization of the fluoride foam group (11.6%) was lower than that of the control group (18.2%) (OR=0.48, 95%CI 0.24 to 0.96, P=0.04); the rate of enamel demineralization of other groups (12.0%) was lower than that of the control group (21.8%) (OR=0.43, 95%CI 0.30 to 0.60, Plt;0.000 01). Two outcomes were low quality in the GRADE system and the other three are very low quality. Conclusion Current domestic evidence shows that topical fluoride is effective to prevent enamel demineralization during the orthodontic treatment. However, given the low methodological quality of most included studies, this conclusion still needs to be further proved by conducting more strictly-designed, high-quality and large-scale studies.
Objective To review the clinical evidence of Pingxiao Capsule for tumor adjuvant treatment so as to provide some decision-making references for clinical practice. Methods We electronically searched CBM, CNKI, VIP, WanFang Data and MEDLINE (from inception to Feb, 2013) to collect the randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) about Pingxiao Capsule for tumor adjuvant treatment. Then, the included studies were summarized and evaluated according to the classification of diseases. Results 1 097 potential relevant articles were searched. We included 41 RCTs and 15 non-RCTs. The results showed that Pingxiao Capsule used as an adjuvant therapy in treating tumor improved the efficacy and reduced the side effects of radiation and chemotherapy, and also improved the quality of survival. Conclusion Current evidence showed that the effectiveness and safety of Pingxiao Capsule combined with radiation or chemotherapy in the tumor treatment is superior to radiation monotherapy or chemotherapy monotherapy. But due to the limited quality of the included studies, the results needed to be further verified by high-quality studies.
