  • SURGICAL TREATMENT OF CAROTID STENOSIS

    Objective To summarize cl inical experience of carotid endarterectomy (CEA) in treating severe carotid stenosis. Methods Between October 1998 and January 2010, 215 patients with carotid stenosis were treated with CEA. There were 140 males and 75 females with an average age of 66 years (range, 51-88 years). Transient ischemic attack (TIA) occurred in127 cases, and 31 cases had history of cerebral infarction. All cases were diagnosed definitely by selective angiography and/or CT angiography, and stenosis degree was more than 80%; contralateral carotid artery was also involved in 45 cases. Ninty-six cases were found to have coronary artery stenosis by coronary angiography. CEA and coronary artery bypass grafting were performed simultaneously in 25 cases. Peripheral arterial disease was found in 43 cases and treated at the same time. Results A total of 155 patients were followed up 6-72 months. The cl inical symptom significantly alleviated in 148 cases postoperatively. Two cases had compl ication of cerebral hemorrhage within 1 week postoperatively; one died and the other was resumed after the conservative treatment. One case had hypoglossal nerve injury. Four cases had injuring marginal mandibular branch of the facial nerve, and no special treatment was given. Restenosis was found in 25 patients, and the stenosis degree was less than 25%; moreover, the patients had no TIA. One case died of heart attack at 3 years of follow-up period. Conclusion CEA is an effective and safe method for treating severe carotid stenosis.

  • The Clinical Application of Lysophosphatidic Acid for Cerebral Ischemic Stroke: A Systematic Review

    Objective To assess the clinical application of lysophosphatidic acid (LPA) as the early warning index for cerebral ischemic stroke (CIS). Methods Trials were collected through electronic searches of PubMed, The Cochrane Library, CBM, CNKI, Wanfang, and VIP (from the date of database establishment to June 2009). We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of the included studies, performed descriptive analysis and meta-analysis with The Cochrane Collaboration’s RevMan 4.2 software. Results A total of 22 studies were included. The results of meta-analyses showed that, there was a significant difference about LPA level in cerebral infarction (CI) group vs. healthy control group (WMD=2.00, 95%CI 1.85 to 2.15), and in transient ischemia attach (TIA) group vs. healthy control group (WMD=2.48, 95%CI 2.18 to 2.78); and a difference was noted about 24 hours LPA level in CI group vs. healthy control group (WMD=2.40, 95%CI 1.81 to 2.99). Conclusions According to the included studies, the contents of LPA is higher in CIS than that in healthy control group. It would be helpful to measure LPA in the TIA period for intervention. However, more high quality trials are expected for further study, in order to prove the value of LPA as early warning index because of the heterogeneity and poor quality of the current included studies.

  • Sodium Ozagrel Combined with Edaravone for Cerebral Infarction: A Systematic Review

    Objective To assess the effectiveness and safety of sodium ozagrel combined with edaravone for cerebral infarction. Methods Such databases as PubMed (1995 to 2010), EMCC (1995 to 2010), CBM (1995 to 2010), CNKI (1995 to 2010), and VIP (1989 to 2010) were searched to collect randomized controlled trials (RCTs) of odium ozagrel combined with edaravone for cerebral infarction. Then the retrieved studies were screened according to the predefined inclusion and exclusion criteria, the data were extracted, the quality of the included studies was evaluated, and meta-analyses were performed by using the Cochrane Collaboration’s RevMan 5.0 software. Results A total of 32 RCTs involving 3 059 cases were involved, among which 1 559 cases were in the treatment group and the other 1500 were in the control group. All studies with comparable baseline data reported the application of random methods without explaining the detailed methods, the blinding method and the allocation concealment. The results of meta-analyses indicated that sodium ozagrel combined with edaravone had significant differences in the effective rate for cerebral infarction compared with both single sodium ozagrel (OR=3.51, 95%CI 2.70 to 4.57) and routine treatment (OR=3.77, 95%CI 2.58 to 5.52), and it had significant differences in treating the defect of neurological function compared with both sodium ozagrel (WMD= –4.26, 95%CI –4.97 to –3.55) and routine treatment (WMD= –3.89, 95%CI –4.96 to –2.82). In addition, Sodium ozagrel combined with edaravone was superior to sodium ozagrel (WMD=13.57, 95%CI 9.84 to 17.30) in improving the ability of daily living. Conclusion This systematic review shows that sodium ozagrel combined with edaravone is quite effective in treating cerebral infarction, and it can improve the nerve dysfunction. This conclusion should be treated cautiously for the poor quality and higher possibility of bias in the included studies which may impact on the power of proof, so more double-blind RCTs with high quality are expected to provide high-quality evidence.

  • Cinepazide Maleate Injection for Cerebral Infarction: A Systematic Review

    Objective To assess the response rate, improvement in neurological function and safety of cinepazide maleate injection for patients with cerebral infarction. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Central Register of Controlled Trials (Issue 1, 2010), PubMed (1948 to March 2010), EMbase (1966 to March 2010) and Chinese Bio-Medicine Database (1978 to March 2010). We also hand searched relevant literatures and obtained unpublished trials from pharmaceutical companies. The Cochrane Collaboration’s software RevMan5.0 was used for meta-analysis. Results Fifteen randomized controlled trials involving 1 456 patients were included. The results of meta-analyses indicated that: 1) Neurological deficits: We identified 11 trials involved 978 patients. Cinepazide maleate injection group compared with the control groups (placebo, Xuesaitong, Dansen and Nimodipine) could significantly improve the neurological deficits. The difference was statistically significant with WMD= – 4.64, 95%CI – 6.43 to – 2.85, WMD= – 2.39, 95%CI – 4.37 to – 0.42, WMD= – 3.67, 95%CI – 5.26 to – 2.07 and WMD= – 6.14, 95%CI – 8.39 to – 3.89, respectively. 2) Response rate: A total of 14 trials involved 1 349 patients were identified. Compared with control groups (placebo, Xuesaitong, Dansen and Nimodipine), cinepazide maleate injection group were more efficient, the difference was statistically significant with RR=1.33, 95%CI 1.16 to 1.54; RR=1.24, 95%CI 1.04 to 1.50; RR=1.33, 95%CI 1.23 to 1.43 and RR=1.29, 95%CI 1.12 to 1.49, respectively. 3) Adverse events: No serious adverse events were observed. But the difference of adverse events reports of headache and skin itching in cinepazide maleate injection group was statistically significant compared with the control groups. Conclusion Current evidence shows that cinepazide maleate injection can reduce neurological deficits in patients with acute cerebral infarction, improve the clinical treatment efficacy without serious adverse events. Due to limited quality of included studies, high-quality, large sample randomized controlled trials are required.

  • Association between Chlamydia Pneumoniae Infection and Cerebral Infarction: A Meta-analysis

    Objective To review the association between chlamydia pneumoniae (CP) infection and cerebral infarction. Methods We electronically searched MEDLINE, BIOSIS, VIP database, and China Full Text Journal Database from Jan. 1990 through Dec. 2007 to identify case-control studies about the association of CP and cerebral infarction. The quality of the included studies was assessed and the RevMan 4.2 software was used for meta-analyses. Results A total of 22 studies were included. The results of meta-analyses showed: ① When the microimmunofluorescence (MIF) method was used to examine CP antibody in serum, the positive rate of the cerebral infarction group was higher than that of the control group when the positive infection was defined by IgA≥1?16 [n=8, OR=2.18, 95%CI (1.49 to 3.49), Plt;0.0001]; but when positive infection was defined by IgA≥1?32 (n=3), IgG≥1?32 (n=6), or IgG≥1?64 (n=5), there were no significant differences in the positive rate between the two groups [OR (95%CI) were 1.47 (0.97 to 2.24), 1.24 (0.82 to 1.86), and 1.23 (0.98 to 1.55), respectively]; ② When the ELISA method was used to examine CP-IgG antibody in serum, the positive rate of the cerebral infarction group was higher than that of the controlled group [n=8, OR=2.40, 95%CI (1.42 to 4.06), P=0.000 2]. ③ The acute and chronic CP infections were associated with the incidence of cerebral infarction [n=4, OR=7.22, 95%CI (2.68 to 19.49); n=4, OR=4.30, 95%CI (3.40 to 7.40)]. Conclusion ① The association between CP infection and cerebral infarction is determined by the positive criterion. IgA antibody is more sensitive than the IgG antibody. When the positive infection is determined by IgA≥1?16, CP infection is associated with cerebral infarction. ② The results of ELISA for examining CP-IgG support the association between CP infection and cerebral infarction. ③ Both acute and chronic CP infections are associated with cerebral infarction, but these associations needed to be proven by more scientific studies.

  • Statins Therapy for C-reactive Protein and Carotid Intima-Media Thickness in Patients with Cerebral Infarction: A Systematic Review

    Objective To determine the effectiveness of statins in reducing C-reactive protein in patients with cerebral infarction and the potency of C-reactive protein as an indicator for preventing cerebrovascular events. Methods We searched PubMed, EMbase, Central Register of Controlled Trials, CBMdisc and CNKI from the date of establishment through August 2008. Bibliographies of the retrieved articles were also checked. Data was extracted and evaluated by two reviewers independently with a designed extraction form. The RevMan 5.0 software was used to carry out meta-analysis. Results Twenty-three randomized trials involving 1946 patients were included. The results of meta-analyses showed the following: statins reduced C-reactive protein compared to the control group (WMD= –5.79, 95%CI –7.32 to –4.26); statins were associated with a reduction of carotid intima-media thickness (IMT) (WMD= –0.21, 95%CI –0.25 to –0.17); atorvastatin greatly reduced C-reactive protein than the simvastatin control group (WMD= –1.78, 95%CI –3.92 to 0.36); statins were associated with a slight improvement in neurological deficit (OR= 2.22, 95%CI 0.94 to 5.21). Conclusion The evidence currently available shows that statins can reduce C-reactive protein and carotid IMT in the patients with cerebral infarction compared to the control group. However, it is not clear whether statins reducing C-reactive protein is correlated to the improvement of neurological deficit and prognosis. Similar trials in future should focus on the relationship between the change of C-reactive protein and clinical outcomes.

  • Meta-Analysis on Relationship between Helicobacter Pyloric Infection and the Subtypes of Ischemia Stroke

    Objective To systematically review the relationship between helicobacter pyloric (HP) infection and ischemia stroke. Methods We searched MEDLINE, BIOSIS, VIP, and China Full Text Journal databases to identify the studies that studied the relationship between HP infection and ischemia stroke. All the studies were strictly screened according to the inclusion criteria, and meta-analyses were performed for the included studies using RevMan 4.2 software.Results Eleven case-control studies involving 1 530 patients with ischemia stroke and 1 451 health controls were included. The results of meta-analyses showed that there was a significant difference in the infection ratio of HP between the patients with ischemia stroke and health controls (OR=1.77, 95%CI 1.38 to 2.28, Plt;0.0001), but this difference was not been found after adjusting some related risk factors (1.22, 95%CI 0.93 to 1.59, P=0.15). The results of subgroup meta-analyses showed these differences were only found in the LAA (large-artery atherosclerosis) subgroup (OR=3.65, 95%CI 2.58 to 5.17) and the SAA (small-artery atherosclerosis) subgroup (OR=1.74, 95%CI 1.30 to 2.34), but was not found in the CE (cardiogenic cerebral embolism) subgroup (OR=1.08, 95%CI 0.58 to 2.02). Conclusion HP infection is associated with ischemia stroke, but the relationships between HP infection and the subtypes of ischemia stroke are different. The association between HP and LAA is ber than that between HP and the other subtypes. More evidence is needed to prove whether Helicobacter pyloric infection is an independent risk factor of ischemia stroke.

  • Fructose-1,6 Diphosphate for Cerebral Infarction: A Systematic Review

    Objective To assess the efficacy and safety of fructose-1,6 diphosphate (FDP) in the treatment of cerebral infarction. Methods We searched MEDLINE, EMbase, Cochrane CENTRAL Register of Controlled Trials, CBM and CNKI in 2006. Randomized controlled trials(RCTs) or quasi-randomized controlled trials involving FDP for cerebral infarction were collected. We assessed the quality of the studies and conducted meta-analyse with The Cochrane Collaboration’s RevMan 4.2. Results Ten RCTs were included, 9 of which were of low quality and only one was graded as high quality. None of the trials reported the number of patients who had died or were dependent at the end of long term follow-up. After 7 to 30 days of treatment, improvement of neurological deficiency was associated with FDP compared with placebo or control [OR 2.45, 95%CI (1.91,3.15)]. There was no statistical difference in the death rate between the FDP and control groups at the end of the treatment [RD –0.01, 95%CI (–0.03,0.01)]. One study found that FDP had a similar safety profile [OR 1.24, 95%CI (0.32,4.75)] to the control group. None of the trials compared the costs in the treatment groups. Conclusions The quality of the published clinical trials on FDP in the treatment of cerebral infarction is poor. FDP may improve short-term neurological deficits, but seems unlikely to decrease mortality. Moreover, we found no evidence to support the long-term efficacy of FDP on mortality, dependency and neurological deficit. Large-scale and high quality clinical trials with sufficient follow-ups are needed to evaluate the role of FDP in the treatment of cerebral infarction.
