AlM: To discuss the application effect of surgical simulator to improve the microsurgical skills in junior ophthalmologist. METHODS: Lecture teaching, training in surgical simulator and operation in animal eyes were received in all these ophthalmologists. Results of the ability of operation in cataract surgery after this training were analyzed. RESULTS: After taught theory, students completed cataract surgical procedures on simulator and the mean test score was 75. 91 ± 6. 53 points. After trained on simulator repeatedly, the mean test score was 85. 57±4. 64 points. There was statistically significant difference ( P<0. 01) . During the third stage of practicing on animal eyes, the score was 89. 77 ± 7. 61 points, there was statistically significant difference compared with former two stages (P<0. 05).CONCLUSlON: Comprehensive training can improve microsurgical skills of junior ophthalmologist, but the long effect need to be observed.

Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.

OBJECTIVE: To study the percentages of polymorphonuclear leukocytes (PMN), mononuclear cells (MNC) and fibroblastic cells (FBC) in different post-traumatic intervals after skeletal muscle mechanical injury in rats. METHODS: The rat model of skeletal muscle mechanical injury was established. The rats were divided into injured groups (6 h, 12 h, 1 d, 3 d, 7 d, 10 d and 14 d after injury) and control group. The percentages of PMN, MNC and FBC in different post-traumatic intervals after skeletal muscle mechanical injury were assessed with HE staining and image analysis. RESULTS: At post-injury 6-12h, the percentages of PMN and MNC infiltration appeared in injured sites and that of PMN reached peak. At 1 d, the percentage of MNC infiltration appeared and reached peak, while that of PMN decreased. At 3-7 d, the percentage of FBC gradually increased, while that of PMN and MNC decreased. At 10-14d, the percentage of FBC reached peak. CONCLUSION The percentages of PMN, MNC and FBC in injured zones showed time-dependent changes, which might be used as reference index for determination of age of skeletal muscle injury.

OBJECTIVE: To study the stability duration of visual acuity after eye injuries in several types, in order to define the earliest and best opportunity for identification. METHODS: 160 cases were divided into five groups, in which their stable visual acuity after injuries were divided into several ranges. Then the relationship between stability duration of visual acuity and their visual acuity level, as well as eye injury types were analyzed. RESULTS: Significant correlation existed between eye injury types, stable visual acuity level and stability duration of visual acuity after injuries. CONCLUSION The earliest and best opportunity for identification after eyes injuries related to injury types and visual acuity level.

Bacillus anthracis collagen-like protein(BclA) is a structural component of the exosporium filaments,as well as the immunodominant antigen on the spore surface.The genes encoding BclA proteins were cloned and sequenced from three Bacillus anthracis strains separated from China.It was founded that the BclA proteins of strain A16R and 40048,containing 388 and 322 amino acids,72 and 50 copies of GXX repeat,5 and 3 copies of 21-amino-acid sequence(GPT)_(5)GDTGTT(BclA repeat) respectively,are different from those reported by foreign scholars;while the BclA protein of strain 40022,containing 370 amino acids,66 copies of GXX repeat,and 5 copies of BclA repeat,is identical with that of strain 53169 reported by others.The results are helpful for the molecular typing of B.anthracis strains,and provide a basis for the elucidation of the pathogenesis and immunogenicity of B.anthracis spore.

Objective:To investigate the influence of sCD80-Linker-sCD40L fusion protein on the unspecific anti- tumor immunity in vitro.Methods:Ovarian cancer SKOV3 cells were separately transfected with recombinant adenoviral vectors containing sCD80-Linker-sCD40L fusion gene,sCD80 gene,sCD40L gene or with control adenovirus.The expres- sion of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of SKOV3 cells was determined by ELISA.Dendritic cells(DCs)were cultured with peripheral blood mononuclear cells from a patient with ovarian carcinoma.DCs and autologous T cells were co-cuhured and were exposed to different supernatants for 48 h. The allostimulatory effects of DCs on T cells were determined by mixed lymphocyte reaction(MLR).The unspecific kill- ing activities of induced T cells against SKOV3/K562 cells were measured by LDH-releasing assay.Results:ELISA assay showed that levels of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of transfeced SKOV3 cells were 2.791 ng/ml,1.956 ng/ml and 1.407 ng/ml,respectively.The fusion protein-exposed DCs ([0.382?0.053]vs[0.167?0.028],P
