Therapeutic effect of Xueniaoan Capsule combined with levofloxacin on chronic bacterial prostatitis / 中草药

Objective: To investigate the clinical efficacy of Xueniaoan Capsule combined with levofloxacin in the treatment of chronic bacterial prostatitis. Methods: A total of 126 patients with chronic bacterial prostatitis were randomly divided into control group (n = 60) and observation group (n = 66). The control group was treated with levofloxacin hydrochloride tablets (0.6 g/d, po) and the observation group was treated with Xueniaoan Capsule (4.2 g/d, po) combined with levofloxacin hydrochloride tablets (0.6 g/d, po). Both groups were continuously treated for eight weeks. The clinical efficacy of the two groups was evaluated through the NIH-CPSI score, prostatic fluid bacterial culture negative conversion rate, and serological parameters. Results: After treatment, the clinical efficacy in the control and treatment groups were 66.67% and 89.39%, respectively, and there were statistical differences between two groups (P < 0.05); Statistical analysis showed that the pain symptom score (5.45 ± 1.12), urination symptom score (3.31 ± 0.70) and quality of life score (3.08 ± 0.55) of NIH-CPSI scale in the observation group were significantly lower than those of the control group (P < 0.05); The negative conversion rate of prostatic fluid bacterial culture was 71.67% in the control group and 92.42% in the observation group, and the difference between the two groups had statistical significance (P < 0.05); The serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and high-sensitivity C-reactive protein (hs-CRP) in the two groups were significantly lower than those before treatment (P < 0.05), while the levels of inflammatory factors in the observation group were significantly lower than those in the control group (P < 0.05). Conclusion: Xueniaoan Capsule combined with levofloxacin is effective in the treatment of chronic bacterial prostatitis, and can effectively relieve the clinical symptoms, improve the rate of prostatic fluid bacterial clearance, and reduce the level of serum inflammatory factors, which has a certain clinical application value.

Fosfomycin tromethamine inhibits the expressions of TNF-α, IL-8 and IL-6 in the prostate tissue of rats with chronic bacterial prostatitis / 中华男科学杂志

<p><b>Objective</b>To investigate the effects of fosfomycin tromethamine (FT) on the expressions of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), and interleukin-6 (IL-6) in the prostate tissue of the rats with chronic bacterial prostatitis (CBP).</p><p><b>METHODS</b>We randomly divided 70 male SD rats into 7 groups of equal number: blank control, CBP model control, positive control, 14 d low-dose FT, 7 d low-dose FT, 14 d high-dose FT, and 7 d high-dose FT. The CBP model rats in the latter five groups were treated intragastrically with levofloxacin at 100 mg/kg/d for 30 days and FT at 200 mg/kg/d for 14 and 7 days and at 300 mg/kg/d for 14 and 7 days, respectively. Then we collected the prostate tissue from the animals for determination of the levels of TNF-α, IL-8 and IL-6 by ELISA.</p><p><b>RESULTS</b>Compared with the blank controls, the CBP model rats showed significantly increased levels of TNF-α (［19.83 ± 6.1］ vs ［32.93 ± 6.21］ ng/g prot, P <0.01), IL-8 (［8.26 ± 0.52］ vs ［16.2 ± 2.84］ ng/g prot, P <0.01) and IL-6 (［1.55 ± 0.11］ vs ［2.51 ± 1.06］ ng/g prot, P <0.05) in the prostate tissue. In comparison with the CBP model controls, the levels of TNF-α and IL-8 were remarkably decreased in the groups of positive control (［20.54 ± 5.78］ ng/g prot, P <0.01; ［12.43 ± 4.02］ ng/g prot, P <0.05), 14 d low-dose FT (［21.95 ± 6.48］ ng/g prot, P <0.01; ［11.11 ± 2.86］ ng/g prot, P <0.01), 7 d low-dose FT (［23.8 ± 6.93］ ng/g prot, P <0.05; ［12.43 ± 4.02］ ng/g prot, P <0.05), 14 d high-dose FT (［19.97 ± 2.58］ ng/g prot, P <0.01; ［8.83 ± 1.32］ ng/g prot, P <0.01), and 7 d high-dose FT (［21.97 ± 3.38］ ng/g prot, P <0.01; ［12.68±1.97］ ng/g prot, P <0.05). No statistically significant differences were observed between the positive control and FT groups in the contents of TNF-α, IL-8 or IL-6 (P >0.05). The expression of IL-6 was markedly reduced in the 14 d high-dose FT group as compared with the model controls (［1.76 ± 0.46］ vs ［2.51 ± 1.06］ ng/g prot, P<0.05) but exhibited no significant difference between the CBP model control and the other groups (P >0.05).</p><p><b>CONCLUSIONS</b>Fosfomycin tromethamine inhibits the expressions of TNF-α, IL-8 and IL-6 in the prostate tissue, suppresses its inflammatory reaction, promotes the repair of damaged prostatic structure, and thus contributes to the treatment of chronic bacterial prostatitis in rats.</p>

Effect of periodontitis on rats with chronic bacterial prostatitis / 局解手术学杂志

Objective To study the effect of periodontitis on rats with chronic bacterial prostatitis. Methods A total of 80 male rats were randomly divided into the 4 weeks group (n=40) and the 8 weeks group (n=40), and then the two groups were randomly divided into the normal control group (N=10), the periodontitis group (PE=10), the chronic bacterial prostatitis group (CBP=10), and the peri-odontitis+chronic bacterial prostatitis group (CBP+PE=10) respectively. The pathological changes, inflammation score, level of TNF-αand IL-1β, and indicators of periodontal of all rats were observed. Results In the 4 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P0. 05). The pathological changes, inflammation score,TNF-αlevel ,IL-1 β level in CBP+PE group and CBP group were higher than that in N group and PE group (P0. 05). In the 8 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P0. 05). The pathological changes, inflammation score, TNF-α level , IL-1 β level in CBP +PE group and CBP group were higher than that in N group and PE group (P0. 05).

Pathogenic Bacteria Causing Chronic Bacterial Prostatitis:An Investigation into Their Spread Status and Drug-resistance / 中华医院感染学杂志

OBJECTIVE To investigate the spread status and drug-resistance of pathogenic bacteria causing chronic bacterial prostatitis among the senile patients,and provide the reference for clincal diagnosis and treatment.METHODS Prostatic fluid from the senile patients with chronic bacterial prostatitis was collected,and bacterial cultures and susceptibility tests were performed.The data were analyzed statistically.RESULTS Among 216 prostatic fluid specimens from the senile patients with chronic bacterial prostatitis,140 isolates of pathogenic bacteria were detected.In these strains,Gram-positive cocci accounted for 60.0% and most of them were Staphylococcus aureus.Gram-negative bacilli accounted for 40.0% and most of them were Escherichia coli.Pathogens causing prostatitis have been resistant to the common antibiotics.Among the total staphylococci,meticillin-resistant Staphylococcus(MRS) accounted for 34.8%.And among the total Enterobacteriaceae,ESBLs producing bacteria accounted for 35.6%.CONCLUSIONS Chronic bacterial prostatitis in the senile patients possesses intractability and persisting.It is important to monitor the pathogens and their drug-resistance.

Sperm Motility in Chronic Nonbacterial Prostatitis: Related to Antisperm Antibody and Seminal Cytokine and Seminal Plasma Composition / 대한비뇨기과학회지

Seminal inflammatory white blood cells in patients with chronic nonbacterial prostatitis may be related to the decrease of semen quality affecting fertility. So we evaluated the change of sperm motility, the levels of antisperm antibodies, the seminal levels of various cytokines and the change of seminal biochemical compositions that may affect sperm motility in the control group. We also examined chronic nonbacterial prostatitis with pyospermia to establish the role of seminal inflammatory white blood cells on alteration of sperm motility. The relation between various affecting factors and sperm motility were also evaluated. Titers of antisperm antibodies were low in patients with chronic nonbacterial prostatitis. Interleukin-1a and interleukin-8 of seminal inflammatory cytokines were present in increased quantities in patients with chronic nonbacterial prostatitis and interleukin-8 of these increases were correlated to sperm motility. Among the seminal composition, the level of zinc was decreased significantly which was not correlated to sperm motility. In conclusion, sperm motility was decreased and alterations in interleukin-8 of seminal cytokines were correlated with sperm motility in chronic nonbacterial prostatitis.
