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 investigate the protective effect of c-jun N-terminal kinase (JNK)inhibitor SP600125 against acute liver failure in mice.Methods Fifty-five male C57/BL6 mice were divided into control group (n =30) and SP600125 group (n =25).The animals were given an intraperitoneal injection of D-galactosamine (D-GalN,400 mg/kg body weight)/lipopolysaccharide (LPS,30 μg/kg body weight).The control group and SP600125 group were given 10％ dimethyl sulfoxide (15 mL/kg body weight) or SP600125 (75 mg/kg body weight) subcutaneously 12 h and 1 h before D-GalN/LPS administration,respectively.D GalN/LPS induced mouse JNK activation was detected by immunohistochemistry for phospho JNK (p-JNK).D-GalN/LPS induced mouse liver cell apoptosis was detected by immunohistochemistry for Caspase-3 and TdT-mediated-dUTP nick endlabeling (TUNEL).Serum alanine transaminase (ALT) level was tested to assess liver injury.Survival rate of mice within 24 h after D-GalN/LPS administration was observed.The comparison between groups was done by t test and survival rate was analyzed by Kaplan-Meier method.Results JNK activity in liver tissues,as indicated by observation of p-JNK positive cells by immunohistochemistry,was diminished 4 h after D-GalN/LPS administration in SP600125 group.Reduced Caspase-3 activity was observed 6 h after D-GalN/LPS administration in SP600125 group (as indicated in immunohistochemistry by Caspase-3 positive cells).Mice in SP600125 group showed significantly lower TUNEL-positive cell count than control group (43.0±24.5 vs 194.7±73.8; t=9.743,P=0.000).Serum ALT level 6 h after D-GalN/LPS administration was (24.0±54.7) U/L in SP600125 group,which was significantly lower than that in control group [(1234.4±478.4) U/L; t=4.734,P=0.0015].SP600125 also significantly improved the survival rate within 24 h after D-GalN/LPS administration (4/5 vs 1/10； x2=5.225,P=0.0223).Conclusions JNK inhibitor SP600125 exerts protective effects against D-GalN/LPS induced acute liver failure in mice by suppressing JNK activation and hepatocyte apoptosis.

The 1,095 bp gene encoding peroxidase from Coprinus cinereus was synthesized and integrated into the genome of Pichia pastoris with a highly inducible alcohol oxidase. The recombinant CiP (rCiP) fused with the a-mating factor per-pro leader sequence derived from Saccharomyces cerevisiae was secreted into the culture medium and identified as the target protein by mass spectrometry, confirming that a C. cinereus peroxidase (CiP) was successfully expressed in P. pastoris. The endoplasmic reticulum oxidoreductase 1 (Ero1) and protein disulfide isomerase (PDI) were co-expressed with rCiP separately and simultaneously. Compared with the wild type, overexpression of PDI and Erol-PDI increaseed Cip activity in 2.43 and 2.6 fold and their activity reached 316 U/mL and 340 U/mL respectively. The strains co-expressed with Erol-PDI was used to high density fermentation, and their activity reached 3,379 U/mL, which was higher than previously reported of 1,200 U/mL.

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.
