AlM: To learn the changes of the tear film before and after the trabeculectomy of glaucoma and explore the incidence of dry eye and the prevention and control measures.METHODS:The 36 patients (60 eyes) of glaucoma were examined in detail before 3d of trabeculectomy and after the surgery at 3, 7, 14 and 30d. The examinations include lower eyelid central river of tears, break-up time ( BUT) , Schirmer I test ( S I t ) and staining scores of corneal fluorescein under slit lamp microscope.RESULTS:The tear meniscus height of central lower eyelid was increased and the tear film BUT was shortened at the same time, the scores of S I t was reduced and corneal fluorescein staining score was increased at postoperative 3 and 7d compared with that of preoperation. The tear meniscus height of central lower eyelid, tear film BUT and Slt and score of corneal fluorescein staining began to recover in most of the affected eyes after surgery 14d. At 30d after surgery, 22%of patients tear film failed to recover to the preoperative level; dry eye occured in 18% preoperative eyes with normal tear film.CONCLUSlON:Trabeculectomy of glaucoma may affect the stability of the tear film and some patients showeing obvious dry eye and should be intervened and treatmented timely.

OBJECTIVE To retrospectively analyze the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) secondary to the sudden deafness (SD) and to explore the possible pathogenetic mechanism, diagnosis and treatment. METHODS 218 cases of the SD in our department were retrospectively analyzed, and 37 patients with primary BPPV during the same period were used as control group. All patients were confirmed by the examination of Dix-Hallpike and the roll check,the primary disease (sudden deafness) of secondary BPPV patients were in line with the Chinese Medical Association diagnostic criteria. RESULTS In all these patients with SD,there were 91 cases with BPPV secondary to the SD. There were 67 cases of BPPV of posterior semicircular canal and 21 cases of BPPV of lateral BPPV semicircular canal. Besides, 3 cases were of multi-semicircular canal affected. All patients with BPPV were diagnosed as the same ears as the SD. The symptoms were alleviated and initial success rate was 68.1%. During 6-22 month follow-ups, total success rate was 100%, and recurrence rate was7.7% (7/91). The hearing recovery of high frequency is worse than that of the low frequency. There were 2 cases of recurrence in lateral BPPV group, 5 cases in posterior BPPV group. All were cured by reposositioning maneuver. All patients with primary and secondary BPPV were cured with Epley maneuver or Barbecue roll maneuver, and the curative effect of them is similar. CONCLUSION The occurrence of BPPV may follow SD,and the majority of BPPV secondary to the SD occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy for secondary BPPV.

Objective:To investigate the effect of HLA genetic susceptibility and NK cell receptors and immune response on the occurrence and development of the Cervical cancer.Methods: Select the 200 patients confirmed by the pathological biopsy in our hospital from January 2013 to January 2014 as the observation group.At the same time,randomly select the 200 healthy women as the control group.Both of them blood 2 ml peripheral blood,sample the cervical cell from the observation group.Having the cytological ob-servation and the DNA′s probe of the HPV,observe two group′s HPV infection rates and HLA′s parting.Results: The HPV infection rates of the observation group is 91%,and the rates of the control group is 16%.The differences between them were all significant(P<0.05).The HLA-KIR*1003,HLA-KIR*14,HLA-KIR*17,HLA-KIR*02,HLA-KIR*12 distribution frequency of the observation group are 41%,39%,35%,15%,53%.The HLA-KIR*1003,HLA-KIR*14,HLA-KIR*17,HLA-KIR*02,HLA-KIR*12 distribution frequency of the control group are 18%,15%,14%,52%,89%.The differences between them were all significant ( P<0.05).Among them The HLA-KIR*1003, HLA-KIR*14, HLA-KIR*17 distribution frequency of the observation group are significantly higher than the control group, HLA-KIR*02 , HLA-KIR*12 distribution frequency of the observation group are significantly lower than the control group.Conclusion:During the occurrence and development of the Cervical cancer,the HLA-KIR*1003,HLA-KIR*14,HLA-KIR*17 may be the risk factors for the Cervical cancer;the HLA-KIR*02,HLA-KIR*12 may be the protective factors for the Cervical cancer.

Objective: To clinically evaluate the efficacy of electrolyzed oxidizing water (EOW) as a root canal irrigation solution on disinfecting bacteria and removing the smear-layer to keep the non-bacterium state in the root canal. Methods: In the first experiment, 108 single-rooted teeth that needed root canal treatment were randomly divided into two groups. EOW was used as the root canal irrigation solution in the experimental group while 30 ml/L H2O2, saline solution, and 75 g/L EDTA solution were used as controls. Bacteriological examinations were conducted from each tooth before and after treatment with the root canal irrigation solutions. In the second experiment, the 20 fresh human extracted teeth were divided into two groups and treated as same as the first experiment in root canal preparation and irrigation. After irrigation, the apical canal wall was observed using SEM. Results: There was no significant difference in bacterial growth and removing the smear layer between the group using EOW and that using saline solution, 30 ml/L H2O2 and 75 g/L EDTA solution. Conclusion:The results indicate EOW is useful as a clinical root canal irrigation solution.
