The present study aimed to compare the clinical efficacy of a 0.4% carbomer gel and 1% carboxymethyl cellulose (CMC) containing artificial tears in treatment of dry eye patients. Sixty subjects with mean age of 45.89 years who had symptoms and signs of dry eye were enrolled in this prospective, investigator-masked and stratified random sampling study. The subjects were divided into two parallel groups with 30 subjects (60 eyes) in each group. One group received carbomer gel, and the other group received 1% CMC containing artificial tears. Subjects received the drops 3 to 4 times or more per day for 3 months. At the first visit time, the precorneal residence time of these two drops was measured. The efficacy was assessed by comparing the subjective symptoms (ocular dryness, foreign body sensation, burning sensation and pain), and the objective test results of tears breakup time, Schirmer's test and corneal fluorescein staining prior to the study and after the treatment. As a result, the ocular residence time of carbomer gel was significantly longer than that of 1% CMC (P<0.001). Most of the primary subjective symptoms and objective test results were improved after treatment in both carbomer gel group and 1% CMC group. As to the improvement of each symptom and objective test result, carbomer gel was more effective than 1% CMC group (P<0.01). In conclusion, carbomer gel had longer precorneal residence time and was more effective than 1% CMC in the treatment of patients with dry eyes.

OBJECTIVETo investigate the status of human papillomavirus ( HPV) infection and its genotypes in male patients in Zhenjiang area.
METHODSUsing PCR and reverse dot blot hybridization, we determined the genotypes of HPV DNA in 245 male patients at our Clinic of Dermatology and STD.
RESULTSThe total rate of HPV infection was 43.67% (107/245), and 18 subtypes were detected. Among the 107 HPV-positive cases, low-risk, high-risk, and combined high- and low-risk infections accounted for 39.25% (42/107), 38.32% (41/107), and 22.43% (24/107), respectively. The most notable low-risk HPV types were HPV6 and HPV11, and the most notable high-risk HPV types were HPV16, HPV52, and HPV58. The rates of single infection and multi-infection were 53.27% (57/107) and 46.73% (50/107), respectively. One case had the most types, infected with 8 genotypes. No statistically significant differences were observed in the total rate of HPV infection among different age groups (Χ2 = 7.999, P > 0.05).
CONCLUSIONThe dominant subtypes of HPV infection in male patients in Zhenjiang area were HPV6, HPV11, and HPV16. The most common subtypes were HPV6 and HPV11 in low-risk infection, and HPV16, HPV52, and HPV58 in high-risk infection.

Objective: To study the rehabilitation efficiency of adjuvant derma transplantation in treatment of front palate fistula. To find a better way to solve the problem of correcting the front fistula in short of the nearby tissue. Methods: Established the front fistula model in the oral and nasal cavity in the front of the palate with surgery. 30 Japanese big ear rabbits were divided into 2 groups. One month after operation, 15 rabbits were operated with the nearby tissue into the inner of nasal cavity and by transplanting their back skin while the others were treated only with the nearby tissues. The rehabilitation process and the histological changes of the palate were observed. Results: All dermal flaps survived after transplantation. This surgical method got a satisfying effect(P<0.05). The rate of success for correcting with single nearby tissues was lower. Conclusion: Adjuvant derma transplantation for rehabilitation of the front palate fistula is effective and reliable in the rabbits. The combination of the nearby tissue and homeochronous derma transplantation might be a good mode for correcting the front fistula in short of the nearby tissues.
