Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

Methods A total of 126 S. aureus strains were isolated. The minimum inhibitory concentrations (MICs) of 4 representative monovalent and bivalent disinfectants were determined. Polymerase chain reaction (PCR) was employed to analyze the prevalence of qacA gene in these strains. Disk diffusion method was used to identify methicillin-resistant S. aureus (MRSA).Results Of the 126 S. aureus strains, 12 were positive for qacA gene. The prevalence of qacA in these strains was 9.5%. The prevalence of qacA gene in MRSA was 17.3%. Conclusions qacA gene is prevalent in the clinical isolates of S. aureus.

AIM: To analyze the direction and degree of static cyclotorsion component (SCC) and dynamic cyclotorsion component (DCC) in corneal refractive surgery.
METHODS:Retrospective analysis. Totally 130 patients (260 eyes) with corneal refractive surgery in our hospital, according to the operation method were divided into femtosecond laser - assisted laser in situ keratomileusis (FS-LASIK) group and T-photorefractive keratectomy (T-PRK) group, the differences of the parameters of the two groups were compared; the differences of SCC success rate, SCC, DCC, and the eyeball rotation direction were compared between the two groups; correlation analysis on SCC, DCC and the parameters of postoperative patients were performed.
RESULTS: High order aberrations and spherical aberration in the T-PRK group after operation was higher than those of FS - LASIK group, and the difference was statistically significant (P<0. 05); in T-PRK group SCC in the operation was successful in 98 eyes, the success rate was 81. 7%; in FS-LASIK group SCC in the operation was successful in 82 eyes, the success rate is 58. 6%, the difference of SCC success rate between the two groups was statistically significant ( P < 0. 05 ); SCC in T - PRK group was 3. 52o ±2. 17o and FS-LASIK group was 3. 49o ±2. 26o, there was no significant difference (P>0. 05); DCC in T-PRK group (2. 86o±1. 14o) was higher than that of FS-LASIK group ( 2. 17o ± 1. 09o), and the difference was statistically significant (P<0. 05). There was no statistical difference in the direction of rotation of the eyeball in operation between the two groups (P>0. 05). The SCC of subjects in operation was positively correlated with UCVA, BCVA, spherical equivalent refraction and high order aberrations ( P < 0. 05 ); the DCC of subjects in operation was positively correlated with UCVA and high order aberrations (P<0. 05).
CONCLUSION: The success rate of SCC in T - PRK surgery is higher than that in LASIK, DCC in T - PRK surgery is higher than that in LASIK, and accurate measurement of SCC and DCC can be effective to compensate for it.

?AIM: To compare postoperative anti -inflammation effect and safety between bromfenac sodium eye drops and pranoprofen eye drops in patients after laser epithelial keratomileusis ( LASEK) .? METHODS: In the prospective, randomized and controlled study, 100 patients ( 200 eyes ) undergoing LASEK were randomized into the bromfenac sodium group (100 eyes) and control group (100 eyes).Patients in bromfenac sodium group received bromfenac sodium hydrate ophthalmic solution eye drops twice a day in 3d before surgery and 2wk after surgery, while the patients from the control group were given proanoprofen eye drops 4 times a day in the same period.At 1, 3, 5d, 1 and 3mo after surgery, irritative symptoms grade, duration of irritation, time for corneal epithelial healing, cornel haze, uncorrected visual acuity and intraocular pressure ( IOP ) were observed and compared between the two groups. Quantitative data were analyzed using independent samples t-test and ranked data were statistically analyzed using the Mann-Whiteney rank sun test.?RESULTS:There was no significant difference between two groups in irritative symptoms grade ( P =0.317 ), neither was existed between two groups in uncorrected visual acuity after surgery (P>0.05).There was no statistical significance in the time for corneal epithelial healing between two groups (P=0.551).?CONCLUSION: Bromfenac sodium eye drops ( 1g/L ) can achieve the same therapeutic effect as pranoprofen eye drops after LASEK.
