Methods:Specific-pathogen-free female SD rats with 7-9 weeks old were randomly divided into model group, levofloxacin group, low-dose Fuzheng Qingre Tonglin group, high-dose Fuzheng Qingre Tonglin group, levofloxacin+Fuzheng Qingre Tonglin group (n=8 in each above group), and also there was a control group with 5 rats. Each group was administered intragastrically 2 days after model establishment for 14 consecutive days. The general condition of the rats was observed. Renal pathological changes were observed by light microscopy under hematoxylin-eosin staining. The number of white blood cells and the percentage of neutral particles (NEUT%) were detected. ELISA was used for the determination of C-reactive protein (CRP), CD4+, CD8+ in the blood, and secretory immunoglobulin A (SIgA), N-acetyl-β-D-glucosidase (NAG) molecules in urine. Results: There were a large number of inflammatory cells in the kidney of the model group and the levofloxacin group. The inflammatory cells in the treatment group were significantly reduced. The NEUT% and CRP in the blood of each treatment group and the NAG in the urine were significantly lower than those in the model group (P<0.05), except levofloxacin group. Compared with the model group, except for the levofloxacin group, serum CD4 concentration and CD4/CD8 ratio in the other treatment groups were significantly decreased, and CD8 molecules were significantly increased (P<0.05). Conclusion: "Fuzheng Qingre Tonglin" can alleviate systemic and local inflammation of complicated urinary tract infections in rats. It may also have the effect of re-sensing the insensitive antibacterial drug to bacteria and may have the function of regulating immune function and protecting kidney function in rats.展开更多

The aim of this study is to compare recurrence rates of UTI in postmenopausal women with DM after treatment with nitrofurantoin, the agent of first choice following the Dutch guidelines, with two other common prescribed antibiotics trimethoprim and norfloxacin. Methods: We used a PHARMO database with pharmacy dispensing data. A total of 8534 postmenopausal (>55 years) women with DM who received a first course of nitrofurantoin, trimethoprim or norfloxacin were included. The UTI recurrence rates after treatment with these three different antimicrobial agents were compared. Recurrence was defined as a second prescription for nitrofurantoin, trimethoprim or norfloxacin or a first with fosfomycin, amoxicillin, fluoroquinolones, or trimethoprim/sulfamethoxazole between 6 and 30 days after inclusion. Results: Postmenopausal women with DM had significantly more UTI recurrences when they were treated with nitrofurantoin (22.7%) compared to trimethoprim (17.7%) or norfloxacin (14.2%) irrespective of the treatment duration. There was a trend that longer treatment duration was associated with higher recurrence rates. Conclusions: Postmenopausal women with DM had more UTI recurrences when they are treated with nitrofurantoin, agent of first choice, compared to trimethoprim or norfloxacin.展开更多

The effects of the therapeutic method adopted for the urinary rehabilitation are directly related to the life quality and survival time of the paraplegic patients. Since 1999-2002, the authors had applied Chinese herbal medicine combined with acupuncture for the urinary rehabilitation in 52 paraplegic patients, with quite good therapeuticresults as reported in the following.展开更多
