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)

Objective :To study the two common method of internal irradiation for nanometer-iron nuclide,and how to estimation of the absorbed dose for each of them.Methods:We chose the nanometer-iron nuclide emitting β-ray during the decay period,Respectively,Arterial injected into the liver or percutaneous puncture direct inject into the liver.Results:Through the formula,a few nanometer-iron nuclide can produced greater radiation.Conclusion:The estimation of absorbed dose depends on the therapy method.

Objective: To predict the medical expenses and distribution of different medical payments of urban residents in Kunming, who are covered by the medical insurance scheme. Methods: We created a static micro-simulation model for predicting and evaluating the 2008-2010 medical insurance scheme for urban residents of Kunming. The main datasets used for constructing the model included: a 0.1% population sample dataset from the national census of 2000 and a dataset of urban employees and retirees under the social medical insurance scheme. Other data used in the model involved the aggregated results of 1% population survey of Kunming conducted in 2005. Results: Based on the population model of 2005, the population information and the data of employees and retirees covered by the social medical insurance scheme were integrated. The model provided information on resident incomes, medical expenses, medical expenses of outpatient services and severe illness; and the different kinds of payments could be forecasted by the model. Conclusion: Results of the present research can help the government in making relevant heath policies while ensuring the sustainable development of medical insurance scheme.

Objective: To investigate the population distribution according to different groups of people, the potential urban residents for medical insurance scheme, and to predict the income trends of individuals and families. Methods: An urban population model was created for China's medical insurance reform by using microsimulation modeling techniques. The first step was to construct the population structure for the period of 2005-2010, and update the Census sample population of 2000 to 2005-2010 according to the target population structure. Then the updated Census dataset was statistically matched with the individual dataset of insured employees and retirees. Results: The micro-population model for urban residents was constructed. The distribution of urban population with potential to enter the medical insurance was obtained by the constructed model. In addition, the distribution of family income was also obtained. The constructed model could be used for analysis and simulation of the major illnesses in the outpatient department and treatment procedure during hospitalization of insured residents. Conclusion: The findings of this research can help the government to take full consideration of the medical service demands of residents in making relevant medical insurance policies, so as to facilitate the sustainable development of medical insurance policies.
