【Abstract】 Objective To evaluate the results of glucosamine hydrochloride in the treatment of knee degenerativeosteoarthritis (DOA) . Methods From February 2006 to January 2007, 60 patients with knee DOA were treated with glucosaminehydrochloride,including 15 males and 45 females. The ages of patients ranged from 41 to 67 years with an average ageof 57.5 years. The disease course ranged from 6 months to 3 years. Oral glucosamine hydrochloride was given twice a day, each750 mg, for a 6-week course of treatment; another course of treatment was repeated after 4 months. After two courses of treatment,the international standard DOA score of Lequesne index was used to evaluate the rest of knee pain, sports pain, tenderness,joints activity, morning stiffness and walking abil ity. Results All 60 patients finished treatment, various cl inical symptomsfor DOA disappeared completely in 31 cases and subsided in 27 cases; the cure rate was 51.7% and the total response rate was96.7%. The scores of rest pain, sport pain, tenderness, joints activity, morning stiffness and the abil ity to walk for knee after treatmentwere 0.5±0.2,0.7±0.4,0.8±0.3,0.9±0.4,0.6±0.3 and 0.9±0.4, showing statistically significant differences (P lt; 0.01) whencompared with preoperation (1.6±0.5,2.1±0.4,2.2±0.5,1.8±0.6,1.7±0.4 and 2.0±0.4). Adverse effect occurred in 3 cases (5%)and the patients recovered without special treatment. Conclusion Glucosamine hydrochloride can cure knee DOA withsymptom-rel ieving and joint function-improving action.
Objective To assess the clinical effectiveness and safety of inductive treatment with arsenic trioxide （As203） for acute promyelocytic leukemia （APL）. Methods Randomized controlled trials （RCTs） were identified from MEDLINE （1966 -July, 2005 ）, EMBASE （1984 -July, 2005 ）, The Cochrane Library （ Issue 3, 2005） and CBM- disc （1978 -July, 2005）. The references of eligible studies were handsearched. RCTs of As203 treating for APL were included. Data were evaluated and extracted by two reviewers independently with designed extraction form. RevMan 4. 2.7 software was used for data analysis. Results Six RCTs involving 323 patients were included. Two studies reported that there was no statistical difference between As2O3 group and all-transretinoic acid （ATRA） group in mortality for patients with APL or APL patients with complications of desseminated intiavascular coagulation or cerebra hemorrhage. The pooled result of 4 studies showed that there was no statistical difference with RR 0.98, 95 % CI 0.86 to 1.12 in complete remission （CR） rates between the two groups. The result of one study showed that the CR rate of patients with intravenous injection of As203 in 2 divided dosages with longer injection duration was higher with RR 1.31, 95% CI 0.86 to 1.12 compared with those with a single intravenous injection. Adverse effects in As2O3 group were less than ATRA group. Conclusions Inductive treatment with As2O3 for acute promyelocytic leukeuia has similar mortality and CR with less adverse effects compared with ATRA. More trials of high quality are required.
Objective To assess the clinical efficacy and safety of Xingnaojing for treating cerebral infarction. Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1966 to April 2005), EMBASE (1984 to April 2005), Cochrane Controlled Trials Register (Issue 2, 2005), CBMdisc (1978 to April 2005). We handsearched the related published and unpublished data and their references. All trials about Xingnaojing injection for cerebral infarction were included. Data were extracted and evaluated by two reviewers independently with designed extraction from RevMan 4.2.7 software was used for data analysis. Results Thirteen RCTs involving 1203 patients were include .The results of meta-analysis were listed as the following:①Mortality:Compared with danshen ,2 studies showed that Xingnaojing decreased mortality statistically (RR 0.31 and 95% CI 0.14 to 0.70).Compared with cerebrolysin ,1 study showed Xingnaojing didn’t decrease the mortality (RR 0.92 ,95%CI 0.14 to 6.27);②Total effective rate: Compared with Danshen ,4 studies showed that Xingnaojing were more effective (RR 0.92,95% CI 1.12 to 1.42 ); ③ Cure rate: Compared with each control , Xingnaojing had the same cure rate ;④ Adverse effect: The number of adverse drug reaction was small and the symptoms were moderate;⑤Neurologic impairment score:Compared with Danshen ,3 studies showed that Xingnaojing had better improvement (WMD 3.78 ,95%CI 2.30 to 5.26).Conclusions xingnaojing may decrease the mortality and increase the total effective rate of cerebral infarction .More high quality trials are required.
