RESUMO
To determine the correlation between deoxyribonucleic acid (DNA) loads of human papillomavirus (HPV) and recurrence of condylomata acuminata (CA), 31 cases of primary CA and 32 cases of recurrent CA were assayed for the HPV6/11 and HPV16/18 DNA loads by real-time fluorogenic quantitative PCR. The results showed 62 of the 63 cases were HPV6/11 DNA positive (98.4%). The ranges of HPV6/11 DNA contained in primary and recurrent CA were 1.4 x 10(3)-6.7 x 10(7) and 1.2 x 10(4)-3.6 x 10(8) copies/mL, respectively. Of the 62 cases which were HPV6/11 DNA positive, seven cases were also HPV16/18 DNA positive (11.3%). The ranges of HPV16/18 DNA levels in primary and recurrent CA were 1.9 x 10(3)-1.6 x 10(4) and 1.4 x 10(5)-1.7 x 10(7) copies/mL, respectively . The HPV6/11 and HPV16/18 DNA loads in recurrent CA were statistically higher than that found in primary CA (P = 0.041 and 0.023, respectively). The DNA loads of HPV6/11 were correlated with the duration, extent of the disease and frequency of recurrence. There is a significant correlation between loads of HPV DNA and recurrence of CA. These findings have important implications for the treatment of CA.

To determine the susceptibilities of Mycoplasma homonis (M. hominis) to Chinese medicinal herbs in vitro, 30 clinical strains of M. hominis were isolated and identified from the clinical specimen. The susceptibilities of M. hominis to 19 herbs were determined by serial dilution methods in vitro. The results showed that M. hominis was susceptible to Radix Isatidis, Radix Angelicae Dahuricae, Cortex Phellodendri, Radix et Rhizoma Rhei, Fructus Kochiae and Herba Houttuyniae. These findings laid a foundation in treating M. hominis infection with Chinese herbs.

OBJECTIVE: To determine the correlation between DNA load of human papillomavirus (HPV) and recurrence of condyloma acuminata (CA). METHODS: The HPV6/11 and HPV16/18 DNA load of 31 cases of primary CA and 32 cases of recurrent CA were detected by real-time fluorogenic quantitative PCR. RESULTS: Among the 63 CA patients, 62 cases were HPV6/11 DNA positive. The positive rate was 98.4%. The ranges of HPV6/11 DNA load in primary and recurrent CA were 1.4x10(3)-6.7x10(7) copies/ml and 1.2x10(4)-3.6x10(8) copies/ml respectively. Of 62 cases with HPV6/11 DNA positive, 7 cases were HPV16/18 DNA positive (11.3%). The ranges of HPV16/18 DNA load in primary and recurrent CA were 1.9x10(3)-1.6x10(4) copies/ml and 1.4x10(5)-1.7x10(7) copies/ml respectively. The HPV6/11 and HPV16/18 DNA load in recurrent CA were higher than in primary CA (P < 0.05). The DNA load of HPV6/11 was positively correlated with times of recurrence and course of disease (r=0.37 and 0.30 respectively). CONCLUSION: Certain correlation exists between DNA load of HPV and recurrence of CA.
