AlM: To observe the influence of phacoemulsification combined with intraocular lens implantation on retinal thickness changes of macular center fovea using optical coherence tomography ( OCT) in cataract patients.METHODS: Surgical eyes of 60 cases with cataract were as surgery group, the contralateral eye were as controls group. There was no complication before and during the surgery. Macular thickness was examined by OCT preoperatively and 1wk, 1, 3, and 6mo after surgery. The retinal thickness changes of macular center fovea were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test and variance analysis were used in two groups before and after surgery for relevant statistical data analysis (α=0. 05).RESULTS: ln surgery group, the retinal thickness changes of macular center fovea at 1wk, 1, 3mo after treatment had significant differences compared with preoperation (P<0. 05). The retinal thickness changes of macular center fovea at 6mo after treatment had no statistical significance compared with preoperation ( P>0. 05). The retinal thickness changes of macular center fovea was significantly higher than other groups at 1mo after treatment (P<0. 05). The center fovea appeared to be abnormally thickened in 12 eyes, including 10 eyes of single fovea thickening and 2 eyes of cystoid macular edema in 2~4wk following surgery. Eleven eyes of them were resolved till 6mo postoperatively. ln control group, preoperation or after operation for 1wk, 1, 3, and 6mo respectively, P values were without statistical differences ( P > 0. 05 ). There were no statistical significant differences on retinal thickness of macular center fovea between two groups before and 6mo after surgery ( P>0. 05), while there were significant differences at 1wk, 1 and 3mo after surgery (P<0. 05) CONCLUSlON: The retinal thickness changes of macular center fovea increases significantly after phacoemulsification combined with intraocular lens implantation. ln a few of cases appear macular edema, but the majority of patients can be restored, prognosis is good.

OBJECTIVEThis study aimed to compare the treatment effects of simultaneous surgical treatment and stage operation for patients with craniomaxillofacial fracture combined with other injuries.

METHODSFifty patients with maxillofacial fractures combined with other injuries were chosen and divided into simultaneous (28 patients) and staging (22 patients) operation groups. In simultaneous operation group, maxillofacial fracture reduction, internal fixation, and other parts of the surgery were simultaneously operated by relevant departments jointly. In the staging operation group, maxillofacial fracture reduction and internal fixation were performed after treatment of other injuries. Data on the treatment efficacy and associated injuries of the two groups were statistically analyzed.

RESULTSIn the simultaneous operation group, 26 patients had good occluding relation, the maximum mouth opening was (34.5 +/- 3.7) mm, the symmetry and shape of hard tissues recovered well, and the bone plate of one patient was removed because of internal fixation infection. In the staging operation group, 14 patients had good occluding relation, the maximum mouth opening was (28.5 +/- 3.5) mm, the symmetry and shape of hard tissues poorly recovered, and the bone plates of 5 patients were removed because of internal fixation infection. Statistical significance was determined among occluding relation, maximum mouth opening, postoperative complications, and length of stay of the two groups (P< 0.05). Treatment of the simultaneous operation group was more effective than that of the staging operation group.

CONCLUSIONWhen a patient's condition is relatively stable, simultaneous surgical treatment of multiple specialties should be conducted to treat craniomaxillofacial fracture combined with other injuries.

Objective To construct an eukaryotic expression plasmid PeDNA3.1 (+)/Lpp20 and to detect its expression in HeLa cells, and to observe the humoral and cellular immune responses in C57BL/6 mice induced by the Helicobacter pylori Lpp20 DNA vaccine injected intramuscularly. Methods The Lpp20 gene was amplified by PCR. PCR product was subcloned into the eukaryotic expression vector pcDNA3.1 (+)/ Lpp20, and the recombinant plasmid was transfected into HeLa cells using Liposome. After verifying that the Lpp20 antigen gene could be expressed in HeLa cells. Six weeks old C57BL/6 mice were immunized with pcDNA3.1 (+)/Lpp20 or pcDNA3.1 (+) or PBS buffer intramuscularly at 2-week interval for four times. ELISA was used for the quantitative detection of the specific IgG antibody in the sera of C57BL/6 mice and the cytokine IFN-γ in mice spleen lymphocyte culture medium after stimulating by Lpp20. The proliferation response of spleen cells was detected by MTT assay. The Lpp20 gene in muscle was identified by PCR. Results The significant specific antibody titers were detected by ELISA in DNA vaccine groups and the highest titer was 1:1024 after 6 weeks. The cytnkine IFN-γ in mice inoculated with pcDNA3.1 (+)/Lpp20 was increased and reached (410.36±56.23) pg/ml. A significant difference was tested between the experiment group and the control group[(25.26±10.85)pg/ml] ,P <0.01. The proliferation response of spleen cells of DNA vaccine group(SI: 2.37±0.22) was significantly higher than those of mice injected with pcDNA3.1 (+) (SI:1.53+0.47) ,P<0.01. Lpp20 gene could exist constantly in musculature cells of mice. Conclusion The eukaryotic expression recombinant pcDNA3.1 (+)/Lpp20 was successfully constructed. Strong humoral and cellular im-munity can be induced by DNA vaccine of pcDNA3.1(+)/Lpp20 in C57BL/6 mice, which might be helpful for further investigation concerning the immunoprotection of DNA vaccine.
