Methods From January 2004 to December 2009, the clinical data from 54 cases of SBP after cirrhosis were analyzed. The patients underwent the treatment of cefoperazone sulbactam combined with levofloxacin. The therapeutic effect was observed. Results The main clinical manifestations were fever and abdominal pain, and about half of the patients had the typical peritoneal irritation. Only a few patients had elevated peripheral white blood cells (WBC). The WBC count, abdominal effusion polymorphonuclearcyte count and bacteria cultivation were the indexes of diagnosis of SBP. Conclusion The clinical features of post-hepatitis cirrhosis complicated with SBP are not typical. The main pathogenic bacteria is G- bacilli. In the early diagnosis and treatment, cefoperazone sulbactam combined with levofloxacin is effective.
Objective To evaluate the clinical efficacy and safety of pazufloxacin for the treatment of moderate and severe acute bacterial respiratory infections.Methods A multicenter randomized controlled trial was conducted to compare the efficacy and safety of pazufloxacin versus levofloxacin. Patients in the pazufloxacin group were treated with pazufloxacin (500 mg twice daily for 7 to 10 days), and patients in the levofloxacin group were treated with levofloxacin (300 mg twice daily for 7 to 10 days). Results A total of 134 patients were enrolled in the study, 68 cases in pazufloxacin group and 66 cases in levofloxacin group were assessable for clinical efficacy by full analysis set(FAS). At the end of the treatment, in FAS analysis the total cure rates and effective rates were 52.9% and 86.7% in pazufloxacin group, 57.6% and 87.9% in levofloxacin group, in PPS analysis the total cure rats and effective rates were 57.1% and 93.7% in pazufloxacin group respectively, 61.3% and 93.6% in levofloxacin group. The bacterial clearance rates were 92.5% and 94.3% respectively. There were no statistically significant differences between the two groups. Adverse reactions were observed in 16.2% of patients in the pazufloxacin group and in 16.7% of patients in the levofloxacin group. These reactions were mainly local stimulation, nausea and diarrhea. No serious adverse event was reported in either group. Conclusion Pazufloxacin is as effective and safe as levofloxacin for the treatment of moderate to severe acute respiratory infections.

This research was aimed to find the skin irritation and burns treatment effect of wound dressing with microspheres containing levofloxacin. We used reference GB/T16886.10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (P<0.05). The nonhealing wound area of the experimental sample group at the ends of 9 d and 14 d was significantly lower than that of the positive control group (P<0.05). The hydroxyproline content of the experimental sample group at the ends of 6 d, 9 d and 14 d was significantly higher than that of the positive control group and blank control group (P<0.05). The pathology observed of the experimental sample group at 21 d were the earliest appendages. The wound dressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.

Methods Literatures were retrieved from PubMed (1978-October, 2010), EMBASE (1974-October 2010), Cochrane library (2nd volume, 2010), China Academic Journal Network Publishing Database (1978-October, 2010), VIP (1989-October, 2010) and CBM (1978 to October, 2010) by computer, and searched some other relevant journals manually. Chinese and English were both used in the search. Randomized controlled trials (RCTs) on sparfloxacin versus ofloxacin in treating pulmonary tuberculosis were included in this study. Meta-analysis was conducted by RevMan 5.0 software. Results The meta-analysis of 8 included RCTs showed that the sputum negative conversion rate, focus absorption rate, cavity closure rate in the sparfloxacin group were significantly higher than the ofloxacin group (P＜0.05). Conclusions The analysis indicates that combined treatment with sparfloxacin has a better effect in treating MDR-TB than with ofloxacin. However, the reliability of this review may be affected by the number and quality of studies included. Large-scale randomized controlled trials of high quality are needed to confirm the conclusions above.
ObjectiveTo evaluate the bone repair efficacy of the new nano-hydroxyapatite (n-HA)/polyurethane (PU) composite scaffold in the treatment of chronic osteomyelitis in tibia.MethodsA novel levofloxacin@mesoporous silica microspheres (Lev@MSNs)/n-HA/PU was successfully synthesized. Its surface structure was observed by scanning electron microscopy (SEM). Fifty adult female New Zealand rabbits were randomly selected, and osteomyelitis was induced in the right tibia of the rabbit by injecting bacterial suspension (Staphylococcus aureus; 3×107 CFU/mL), which of the method was described by Norden. A total of 45 animals with the evidence of osteomyelitis were randomly divided into 4 groups, and the right medullary cavity of each animal was exposed. Animals in the blank control group (group A, n=9) were treated with exhaustive debridement only. The remaining animals were first treated by exhaustive debridement, and received implantations of 5 mg Lev@PMMA (group B, n=12), 1 mg Lev@MSNs/n-HA/PU (group C, n=12), and 5 mg Lev@MSNs/n-HA/PU (group D, n=12), respectively. At 12 weeks postoperatively, the right tibia of rabbits were observed by X-ray film, and then gross observation, methylene blue/acid fuchsin staining, and SEM observation of implant-bone interface, as well as biomechanical test (measuring the maximal compression force) were performed.ResultsX-ray films showed that the infection were severer than those of preoperation in group A, while the control of inflammation and bone healing of rabbits in group D were obviously better than those at preoperation. The gross observation showed extensive bone destruction in group A, a significant gap between bone tissue and the material in groups B and C, and close combination between bone tissue and the material in group D. The histology of the resected specimens showed that there was no obvious new bone formation around the materials in groups B and C, and there was abundant new bone formation around the periphery and along the voids of the materials and active bone remodeling in group D. The SEM observation of the bone-implant interface demonstrated that no new bone formation was observed at the bone-implant interface in groups B and C. However, bony connections and blurred boundaries were observed between the material and host bone tissue in group D. The biomechanical test showed the maximal compression force of groups B and D were significantly higher than that of groups A and C (P<0.05), but there was no significant difference between groups B and D (P>0.05).ConclusionThe novel synthetic composite Lev@MSNs/n-HA/PU exhibit good antibacterial activities, osteoconductivity, and biomechanical properties, and show great potential in the treatment of chronic osteomyelitis of rabbits.

Methods A total of 68 elder patients with refractory respiratory infections in our hospital from February 2005 to September 2010 were randomly divided into two groups: treatment group (n=34) and control group (n=34). The patients in treatment group were treated with levofloxacin combined with azithromycin; while the patients in the control group were treated with levofloxacin alone. The total treatment periods of both groups were 15 days. The therapeutic efficacy, eradication rate of pathogens and the rate of aelverse reactions were observed. Results The therapeutic effect rate was 64.71% in the treatment group and 32.35% in the control group, and the difference between the two groups was statistically significant (Plt;0.05). The eradication rate of pathogens was 76.19% in the treatment group and 36.36% in the control group, and the difference was significant (Plt;0.05). The rate of the adverse reaction was 5.88% in the treatment group and 8.82% in the control group, and there were no significant differences between the two groups (Pgt;0.05). Conclusion Levofloxacin combined with Azithromycin is effective on refractory respiratory tract infection in elder patients, which can effectively remove the bacteria with few adverse reaction.
Objective To access the effectiveness and safety of levofloxacin in controlling multidrug resistant tuberculosis (MDR-TB). Methods The electronic searches in databases of PubMed, EMbase, The Cochrane Library, CNKI, CBM and VIP, handsearches and other searches were conducted from the date of their establishment to April 2011 for collecting randomized controlled trials (RCTs) on levofloxacin treating MDR-TB. Two researchers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, assessed the quality of the included studies by adopting the Jadad scale, and performed Meta-analysis by using RevMan 5.0 software. Results A total of 31 RCTs involving 2836 cases were included. The results of meta-analysis showed: a) Compared with the placebo group, levofloxacin could increase the sputum negative conversion rate after 3-month taking and at the end of the treatment period; b) Compared with the ofloxacin group, levofloxacin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; c) levofloxacin replacing either ethambutol or streptomycin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; d) Compared with the levofloxacin group, gatifloxacin and moxifloxacin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; e) There was no significant difference in the adverse reaction rate between each of the medication regimens (P=0.19). Conclusion Levofloxacin is more effective for MDR-TB than ofloxacin, ethambutol and streptomycin, but it is inferior to gatifloxacin or moxifloxacin. Its adverse reaction rate is equivalent to other medicines’.
Objective To assess the effectiveness and safety of prulifloxacin in the treatment of urinary tract infection. Methods The double-blind, double dummy and randomized controlled method was adopted. One hundred and forty-four patients were randomized to the treatment group (prulifloxacin , 4 tablets, bid) and the control group (levofloxacin, 4 tablets, bid). The randomization code was produced by computer. The treatment duration for both groups was from 7 to 10 days. Results Data were analyzed on the basis of full analysis sets (FAS) and per-protocol (PP) analysis. The total improvement rates of the trial and control groups were 85.07% and 88.52% respectively by FAS analysis, and 90.48% and 91.53% respectively by PP analysis. There was no significant difference between the two groups in improvement rates (Pgt;0.05). Bacterial negative rates in the trial and control groups were 93.75% and 93.88% respectively by FAS analysis and 97.83% and 97.87% respectively by PP analysis. The results showed no statistical significance difference between the two groups in bacterial negative rates (Pgt;0.05). The adverse events in the prulifloxacin and levofloxacin groups were 2.80% and 5.60% respectively. Conclusion Prulifloxacin has the same clinical effectiveness as levofloxacin with a few toxic adverse effects in the treatment of urinary tract infection.
