Objective:To evaluate the clinical effects of the key-way attachment in fixed restoration of mandibular first and second molar deletion.Methods:A 1 -5-year follow-up study was conducted on 1 6 patients with the reconstruction of mandibular first and second molar deletion.The key-way attachment was used as a connector in the fixed partial denture,with the third molar and 2 sec-ond premolars as the abutments.Results:During 5-year follow-up,1 3 of the fixed partial denture were good-looking,stable and functioning.The abutments were stable,without endodontic and periodontal disease.No absorption of alveolar bone was observed by X-ray examination.3 cases were failure.Bleeding on probing of third molar was observed in 1 patient 1 year after restoration.1 re-tainer of a denture on the third molar was loosing 1 .5 years after restoration.1 patient had dental caries on the third molar 5 years af-ter restoration.Conclusion:The key-way attachment as a connector is useful in fixed partial denture in patients with mandibular first and second molar deletion.

Objective To observe effects of soaking therapy with traditional Chinese medicine on athlete's foot. Methods346 cases of the treatment group (175 cases of erosive type and 171 cases of bullous type) were treated with soaking therapy by traditional Chinese medicine and 335 cases of the control group (170 cases of erosive type and 165 cases of bullous type) were treated with 3% Clotrimazolum ointment. Effects of two groups were compared.Results Effect of the treatment group was obviously more superior to that of the control group (P<0.0001). ConclusionsIt shows easy and effective that patients with athlete's foot were treated by soaking therapy with traditional Chinese medicine.

Objective To study the correlations between diopter,axis length,cornea curvature and thickness in myopia patients. Design Prospective case series.Participant 300 myopic patients who were ready for LASIK.Method 300 myopic patients who were ready for LASIK were selected randomly.They were divided into four groups according to the diopter of myopia:low myopia group (≤-3.00D)41 cases,medium myopia group(＞-3.00D,≤-6.00D)130 cases,high myopia group(＞-6.00D,≤-9.00D)95 cases,and super myopia group(＞-9.00D)34 cases.The axis length,cornea thickness,cornea eurvture and diopter of myopia were detected. Through analysis of variance(ANOVA),Pearson correlation analysis and linear regression analysis,the correlations between axis length, cornea thickness,curvature and diopter of myopia were made out in four groups.Main Outcome Measure Diopter of myopia,cornea curvature,axis length of eye and central cornea thickness.Result The axis length of low myopia group,medium myopia group,high myopia group and super myopia group was(24.32?1.73)mm,(25.33?1.49)mm,(26.04?1.92)mm,(27.47?2.57)mm respectively. There were obvious differences of axis lengths between four groups(P=0.000).The cornea curvature in high myopia group was obviously different from those in low myopia group and medium myopia group.There were no significant differences of cornea thickness among four groups(P=0.409).The axis lengths of eyes respectively had correlations with diopters(r=0.734,P=0.000),vertical and horizontal cornea curvatures(r=-0.312,P=0.000;r=-0.328,P=0.000).Conclusion The main effective factor on the diopter of myopia is the axis length for most patients.For the patients with high myopia,the cornea curvature is another effective factor.With the increase of axis length,the cornea curvature decreases,and the cornea turns flatter.(Ophthalmol CHN,2006,15:321-323)
