OBJECTIVETo study the therapeutic efficacy of Longqingpian combined with Levofloxacin on Type IIIA prostatitis.

METHODSEighty patients with Type IIIA prostatitis were equally randomized into a Longqingpian group and a Puleanpian group, both treated for 12 weeks. The former were given Longqingpian (once 6 tablets, twice a day) combined with Levofloxacin (once 0.2 g, twice a day) during the first 4 weeks, followed by Longqingpian alone (once 6 tablets, twice a day) for 8 weeks. The latter received Puleanpian (once 4 tablets, 3 times a day) combined with Levofloxacin (once 0.2 g, twice a day) in the initial 4 weeks, followed by Puleanpian alone (once 4 tablets, 3 times a day) for 8 weeks. Before and 4, 8, and 12 weeks after the treatment, all the patients were evaluated by The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and EPS examination.

RESULTSAfter 4-week, 8-week and 12-week treatment, total score of NIH-CPSI, and the score of pain, voiding symptoms and the quality of life dropped significantly in both groups compared with pre-treatment (P < 0.05 or 0.01), so did the leukocyte count in EPS (P < 0.05). Compared with the 4-week treatment, total score of NIH-CPSI, and the score of pain, voiding symptoms and the quality of life were shown to be significantly different (P < 0.05) in the Longqingpian group from the 8-week and 12-week treatment, except the leukocyte count in EPS. However, there was no significant difference between the 8-week and 12-week treatment in any of the indexes (P > 0.05). Longqingpian effected significant differences in the above indexes (P < 0.05), while Puleanpian did not after the treatment (P > 0.05). And the lecithin Amato body analysis revealed no significant changes in EPS after the treatment in either group (P > 0.05).

CONCLUSIONLongqingpian combined with Levofloxacin is highly effective for Type IIIA prostatitis, by relieving pain and voiding symptoms, decreasing the leukocyte count in EPS and improving the life quality of the patients.

This research was aimed to find the skin irritation and burns treatment effect of wound dressing with mi- crospheres 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.

OBJECTIVETo evaluate the efficacy and safety of corticoid in combination with an antibiotic in the treatment of chronic nonbacterial prostatitis (CNP).

METHODSWe used the randomized, double-blind and parallel contrasted method, selected 160 CNP patients via the Stamey test, EPS examination and NIH-CPSI scores, and equally randomized them into an experimental group (with 1 case missing) and a control group. The former received prednisone and levofloxacin for 2 weeks followed by another 2-week administration of levofloxacin only, while the latter were given levofloxacin and placebo in the first 2 weeks and placebo only in the next 2. All the patients were evaluated by NIH-CPSI scores and EPS results and followed up for adverse events after 2 and 4 weeks of treatment.

RESULTSThe total NIH-CPSI score, the pain index, voiding index and quality of life (QOL) score in the experimental group were decreased by 9.56 +/- 2.05, 4.59 +/- 1.18, 2.38 +/- 1.24 and 2.59 +/- 2 1.20 after the 2-week treatment, and 11.72 +/- 2.41, 5.51 +/- 1.42, 2.92 +/- 1.17 and 3.33 +/- 1.08 after the 4-week treatment; while those in the control group were reduced by 6.53 +/- 2.70, 3.20 +/- 1.30, 1.40 +/- 1.05 and 1.80 +/- 1.15 after the 2-week treatment, and 8.53 -/+ 2.91, 3.88 +/- 1.44, 2.08 +/- 1.11 and 2.55 +/- 1.33 after the 4-week treatment, with significant differences between the two groups as well as between pre- and post-treatment (P < 0.01), but not between the 2- and 4-week treatment (P > 0.05). Statistically significant differences were also observed in the count of WBCs in EPS between not only pre- and post-treatment, but also the 2- and 4-week treatment (P < 0.01). No serious adverse events were recorded, nor were significant differences in the tolerance to corticoid and placebo.

CONCLUSIONPrednisone in combination with an antibiotic can effectively relieve pain and voiding symptoms, improve QOL and reduce WBC in the EPS of CNP patients, and therefore well deserves to be recommended in clinical application. But its long-term efficacy and tolerance are yet to be further studied.

BACKGROUNDImplanted medical catheter-related infections are increasing, hence a need for developing catheter polymers bonded to antimicrobials. We evaluated preventive effects of levofloxacin-impregnated catheters in catheter-related Psuedomonas aeruginosa (strain PAO1) infection.

METHODSDrug release from levofloxacin-impregnated catheters was measured in vitro. Levofloxacin-impregnated catheters and polyvinyl chloride (PVC) catheters were immersed in 5 ml 50% Luria Bertani medium containing 10(8) CFU/ml Pseudomonas aeruginosa then incubated for 6, 12, 24 or 48 hours at 37°C when bacteria adhering to the catheters and bacteria in the growth culture medium were determined. Impregnated and PVC catheters were singly implanted subcutaneously in mice, 50 µl (10(7)CFU) of PAO1 was injected into catheters. After the first and fifth days challenge, bacterial counts on implanted catheters and in surrounding tissues were determined microbiologically. Bacterial colonization and biofilm formation on implanted catheters were assessed by scanning electron microscopy.

RESULTSDrug release from levofloxacin-impregnated catheters was rapid. Levofloxacin-impregnated catheters had significantly fewer bacteria compared to PVC in vitro. After first and fifth day of challenge, no or significantly fewer bacteria adhered to impregnated catheters or in surrounding tissues compared to PVC. Scanning electron microscopical images after first day displayed from none to significantly fewer bacteria adhering to impregnated implanted catheters, compared to bacteria and microcolonies adhering to PVC catheters. After the fifth day, no bacteria were found on impregnated catheters, compared to clusters surrounding mucus-like substance and coral-shaped biofilms with polymorphonuclear leukocyte on PVC catheters. After the first day of challenge, secretion occurred in all implanted catheters with surrounding tissues mildly hyperaemic and swollen. After the fifth day, minute secretions inside impregnated catheters and no inflammation in tissues, whereas purulent secretion inside PVC catheters and abscesses in surrounding tissues.

CONCLUSIONLevofloxacin-impregnated catheter is a promising new strategy for prevention of catheter-related Psuedomonas aeruginosa infection.

Objective: To explore the clinical characteristics, common pathogens in children with vulvovaginitis. Methods: This was a retrospective cases study. A total of 3 268 children with vulvovaginitis were enrolled, who visited the Department of Pediatric and Adolescent Gynecology, Children's Hospital, Zhejiang University School of Medicine from January 2009 to December 2019. Patients were divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Patients were also divided in to 4 groups according to the season of first visit. The pathogen distribution characteristics of infective vulvovaginitis were compared between the groups. Their clinical data were collected and then analyzed by χ² test. Results: The were 3 268 girls aged (6.2±2.5) years. There were 1 728 cases (52.9%) aged <7 years, 875 cases (26.8%) aged 7-<10 years, and 665 cases (20.3%) aged 10-18 years. Of these cases, 2 253 cases (68.9%) were bacterial vulvovaginitis, 715 cases (21.9%) were fungal vulvovaginitis and 300 cases (9.2%) were vulvovaginitis infected with other pathogens. Bacterial culture of vaginal secretions was performed in 2 287 cases, and 2 287 strains (70.0%) of pathogens were detected, of which the top 5 pathogens were Streptococcus pyogenes (745 strains, 32.6%), Haemophilus influenzae (717 strains, 31.4%), Escherichia coli (292 strains, 12.8%), Staphylococcus aureus (222 strains, 9.7%) and Klebsiella pneumoniae (67 strains, 2.9%). Regarding different age groups, H.influenzae was the most common in children under 7 years of age (40.3%, 509/1 263), S.pyogenes (41.9%, 356/849) was predominantly in children aged 7 to 10 years, and E.coli was predominant in children aged 10 to 18 years (26.3%, 46/175). Susceptibility results showed that S.pyogenes was susceptible to penicillin G (610/610, 100.0%), ceftriaxone (525/525, 100.0%), and vancomycin (610/610, 100.0%); the resistance rates to erythromycin and clindamycin were 91.9% (501/545)and 90.7% (495/546), respectively. For H.influenzae, 32.5% (161/496) produced β-elactamase, and all strains were sensitive to meropenem (489/489, 100.0%) and levofloxacin (388/388, 100.0%), while 40.5% (202/499) were resistant to ampicillin. Among E.coli, all strains were sensitive to imipenem(100%, 175/175). The resistance rates of E.coli to levofloxacin and ceftriaxone were 29.1% (43/148) and 35.1% (59/168), respectively. A total of 48 strains of methicillin-resistant Staphylococcus aureus (MRSA) were isolated with a proportion of 28.3% (45/159) in 3 268 patients. The results of drug susceptibility test showed that all MRSA strains were sensitive to linezolid 100.0% (40/40), vancomycin (45/45, 100.0%), and tigecycline (36/36, 100.0%); the resistance rates of MRSA to penicillin G, erythromycin and clindamycin were 100% (45/45), 95.6% (43/45) and 88.9% (40/45), respectively. All methicillin-sensitive Staphylococcus aureus (MSSA) strains were sensitive to oxacillin (114/114, 100.0%), linezolid (94/94, 100.0%), vancomycin (114/114, 100.0%), and tigecycline (84/84, 100.0%); it's resistance rates to penicillin G, erythromycin and clindamycin were 78.1% (89/114), 59.7% (68/114) and 46.5% (53/114), respectively. The drug resistance rate of MSSA to penicillin G, erythromycin and clindamycin were lower than those of MRSA (χ²=11.71,19.74,23.95, respectively, all P<0.001). Conclusions: The age of consultation for pediatric infectious vulvovaginitis is mainly around 6 years. The most common pathogens are S.pyogenes, H.influenzae and Escherichia coli. Third generation cephalosporins can be used as the first choice of empirical anti-infection drugs. However, the results of drug susceptibility should be considered for targeted treatment.
