Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
Objective To systematically evaluate the effectiveness and safety of China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding. Methods Such databases as PubMed, MEDLINE, Springer, The Cochrane Library, CNKI, VIP, CBM and WanFang data were searched to collect the randomized controlled trials (RCTs) about China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding, and the references of included studies were also retrieved. The retrieval time was from inception to December 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.1 software. Results A total of 11 RCTs were included. Among all 1 075 patients, 544 were in the treatment group, while the other 531 were in the control group. The results of meta-analysis showed that, there were no significant differences in the total effective rate (OR=0.68, 95%CI 0.35 to 1.33, P=0.26) and safety (RR=1.33, 95%CI 0.45 to 3.91, P=0.96) between the China-made omeprazole and imported omeprazole. Conclusion China-made omeprazole is effective and safe in treating acute non-variceal upper gastrointestinal bleeding in comparison with the imported omeprazole.
Objective To conduct Meta-analyses on published literatures about the Jianpi Bushen Decoction combined with western medicine for dysfunctional uterine bleeding (DUB), so as to evaluate its efficacy and safety compared with the western medicine treatment. Methods The following databases such as PubMed (1995 to 2011), EMCC (1995 to 2011), CBM (1995 to 2011), CNKI (1995 to 2011), Wanfang (1989 to 2011) and VIP (1989 to 2011) were searched to collect the randomized controlled trials (RCTs) on Jianpi Bushen Decoction combined with western medicine for DUB. The selection of studies, assessment of methodological quality and data extraction were performed independently by two reviewers according to the Cochrane systematic review methods, and Meta-analyses were performed by using RevMan5.0 software. Results A total of 12 RCTs involving 925 cases were included, of which 471 ones were in the experimental group while the other 454 ones were in the control group. Each study was comparable in baseline data, all with reporting of using random methods, but no mention of detailed random methods, blind methods and allocation concealment. The results of Meta-analyses indicated that compared with single therapy of western medicine, Jianpi Bushen Decoction combined with western medicine for DUB was superior in the total effective rate (OR=5.60, 95%CI 3.25 to 9.67, Plt;0.000 01), bleeding recovery rate (OR=3.79, 95%CI 2.70 to 5.32, Plt;0.000 01), and bleeding recurrence rate (OR=0.14, 95%CI 0.05 to 0.42, P=0.000 5), with significant differences. Conclusions The integrated treatment of Jianpi Bushen Decoction and western medicine has certain effects on dysfunctional uterine bleeding, and it may be a promising treatment option. Due to the poor quality and high possibility of bias of the included studies, more well-designed multi-centered RCTs should be performed.
Objective To discuss the common clinical problems and make the individualized treatment for a patient with obscure gastrointestinal bleeding by means of evidence-based medicine, so as to ultimately control the symptoms and reduce the mortality. Methods After the clinical problems were put forward, the systematic reviews and randomized controlled trials (RCTs) were collected in The Cochrane Library (online), MEDLINE, EMBase, SCIE and CNKI databases, from the date of their establishment to 2010. The treatment protocol was made by combining the assessment of evidence with the willingness of both patient and relatives. Results A total of 30 RCTs and 5 systematic reviews were identified. A rational diagnostic and therapeutic plan was made upon a serious evaluation of the data and willingness of patients. The Mickel’s diverticulum was found through capsule endoscopy, which was then locally excised under laparoscopy. After a 6-month follow-up, the plan proved to be optimal. Conclusion The treatment efficacy in diagnosed obscure gastrointestinal bleeding has been improved by adopting an individualized treatment plan according to evidence-based methods.
Objective To explore an approach of evidence-based treatment for acute hypertensive cerebral hemorrhage. Methods (1) Thoroughly evaluating the patient’s condition. (2) Formulating clinical problems. (3) We searched The Cochrane Library (Issue 1, 2006), Ovid EBM REVIEWS (2001 to 2006), MEDLINE (1980 to 2006) and CNKI (1994 to 2006) for evidence. (4) Assessing evidence. (5) Applying evidence. Results Total 13 relevant studies were retrieved. Results indicated that all kinds of interventions for the treatment of hypertensive cerebral hemorrhage showed different degrees of efficacy, including the Stroke Unit, blood pressure control, mannitol, hemostyptic and neuroprotective agents, promotion of blood circulation and resolving of blood stasis, stereotactic aspiration etc. However, the effects of other interventions need further validation except Stroke Units which had higher quality evidence. Based on the patient’ specific conditions, we recommended the following evidence-based treatment plan: immediate transfer to the Stroke Unit; sequential application of reptilase (within 6 h), citicoline (within 24 h), mannitol and Compound Danshen Injection (after 24 h); temporary withhold of enalapril meleate; monitoring of blood pressure, ECG, renal function and electrolytes; and if intracranial hemorrhage occurs again during the treatment, stereotactic aspiration should be applied. Conclusions Through evidence-based method, an individualized treatment plan could obviously improve the treatment effectiveness and reduce the incidence of adverse effects in patients with hypertensive cerebral hemorrhage.
Objective To explore the effectiveness and safety of exchange of cerebrospinal fluid in the treatment of subarachnoid hemorrhage （SAH）. Methods Sixty SAH patients diagnosed by CT and lumbarpuncture were randomly assigned into a control group （n =30, received conventional treatment） and a treatment group （n =30, received exchange of cerebrospinal fluid plus conventional treatment）. The main complications and effectiveness between the two groups were compared. SPSS 10.0 was used for statistical analysis. Results Compared with the control group, complications of persistent headache （ P =0.002 and 0. 007 respectively）, cerebral vasospasm （ P =0. 028 ） and hydrocephalus （ P =0. 038 ） were fewer in the treatment group. No significant difference in the incidence of rehaemorrhagia was found between the two groups （P = 1. 000）. Better effectiveness was observed in the treatment group （RR. 3.00, 95% CI 1. 014 to 8. 880, P = 0. 044 ）. Conclusions Exchange of cerebrospinal fluid plus conventional treatment is more effective than conventional treatment alone in the treatment of SAH.
Objective To assess the effectiveness and safety of YunNan BaiYao capsules in reducing bleeding quantity during TURP. Methods A double-blind randomized controlled trial was conducted. We randomly allocated 40 patients to the treatment group （ YunNan BaiYao 0.25 g capsule, 2 capsules, q. i. d. , n = 20 ） and the control group （starch capsule, 2 capsules, q. i. d. , n =20）. Patients in both groups were administered three days before operation. Average bleeding quantity, bleeding index of prostate, bleeding intension, length of stay, catheter retention time, and time of washing bladder were observed and compared. Results The average bleeding quantity, bleeding index of prostate and bleeding intension were better in the treatment group than that of the control group with significant difference （P 〈0. 05 ）. The length of stay, catheter retention time and time of washing bladder had no significant difference between the two groups （P 〉0.05）. No obvious adverse effect was observed in both groups. Conclusions YunNan BaiYao capsule can effectively reduce bleeding quantity during TURP without obvious adverse effects.
Objective To explore whether there is enough clinical evidence to confirm that stereotactic aspiration does more good than harm in patients with cerebral hemorrhage. Method A systematic review of all relevant clinical studies on stereotactic aspiration in the treatment of cerebral hemorrhage. Results Eight randomized controlled trials (RCTs) including 757 patients and 17 nonrandomized controlled studies including 1 766 patients, as well as 20 uncontrolled studies including 1 244 patients were identified . All studies reported positive results regarding the effects. However, the quality of the included studies were generally poor. The main problem was that most trials reported them as a RCT, but no description of the method of randomization. Conclusions Stereotactic aspiration in the treatment of cerebral hemorrhage is promising based on present evidence. However, at present, we can not draw definite conclusion whether the treatment does more good than harm compared with noninvasive medical treatment because of the poor quality of included studies. Therefore, more high quality RCTs are required.
Objective To evaluate the relationship between angiotension-converting enzyme (ACE) gene polymorphism and susceptibility to cerebral hemorrhage among the Han Chinese population. Methods We electronically searched CNKI, CBM, VIP, and Wanfang technological periodical full-text databases from January, 1998 to January, 2009. We identified case-control studies of ACE gene polymorphism and cerebral hemorrhage among the Han Chinese population, and assessed the quality of included studies. The data were quantitatively analyzed by RevMan 4.3 software. Results Meta-analysis results showed that the pooled OR value of cerebral hemorrhage subjects among the Han Chinese population with at least one D allele was 1.42 (95%CI1.13 to1.78). The pooled OR values of cerebral hemorrhage with DD and II genotype were 1.9 (95%CI1.32 to 2.74) and 0.80 (95%CI0.63 to 1.01) respectively. Conclusion ACE gene polymorphism is significantly associated with susceptibility to cerebral hemorrhage in the Han Chinese `population.
