Objective To investigate fracture resistance and fracture patterns of maxillary anterior endodontically treated teeth restored with two different shapes of glass fiber post systems.Methods Twenty-four human sound maxillary anterior teeth of similar size were collected,and randomly divided into 3 groups,8 teeth each.After endodontical treatment,they were given the following treatments:Group A:parallel glass fiber posts (coltene parapost fiber lux) and composite core;Group B:taper glass fiber posts (coltene parapost taper lux) and composite core; Group C (control group):intact endodontically treated teeth.Teeth in Groups A and B reserved 2 mm dentin ferrule.Then the teeth were prepared and restored with IPS e.max Press all ceramic crowns.All the teeth were embedded in acrylic resin 2 mm below the cementoenamel junction (CEJ),with the silicon impression material stimulating periodontal membrane.All the specimen were loaded under a universal testing machine,at the palatal junction of incisor third and middle third,with an angle of 135 degree to the longitudinal axis of the tooth until fracture occurred,at a cross-head speed of 1.0 mm/min.Fracture loads and patterns were recorded.Statistical analysis was performed using SPSS software.Results The mean fracture loads in the three groups were as follows:(468.8±142.5) N,(440.2±202.7) N,and (459.0±147.6) N,respectively.There was no significant difference in fracture loads among groups (P＞0.05).The incidence of unfavorable fracture in Group A was higher than Groups B and C.Conclusions There is no significant difference in fracture strength between parallel and taper fiber post groups.However,the group with parallel fiber posts demonstrates a higher risk of unfavorable fracture than the group with taper fiber posts,which indicates that taper fiber posts are more favorable to preserve the remaining tooth structure.

As a crucial component of acupuncture-moxibustion therapy, moxibustion has been extensively propagated and used with its significant efficacy, simple operation, inconspicuous adverse effects and less sufferings. There are a variety of factors that influence the therapeutic efficacy of moxibustion. The influencing factors, including moxibustion dose (moxibustion duration, distance between moxa and skin, size and number of moxa cone), selection of points, moxibustion sensations, and the type of moxibustion were analyzed and summarized, to provide references for approaching the maximum efficacy of moxibustion in clinic.

Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

Lipids of Thamnidium elegans,Mortierella ramanninace,Rhizopus arrhizus,Pythium irregulare and Rhodotorulla aurantiaca were extracted by Soxhlet extraction,supercritical-CO 2 fluid extraction,acid-heating extraction and organic solvent extraction,respectively.Four extraction methods were evaluated on sample treatment,minimum sample quantity,requirements of apparatus,ability of treating sample and content of lipid.The components of fatty acids were analysed by gas chromatography.Soxhlet extraction can acquired maximum lipid content,but it took the most time.Supercritical-CO 2 fluid extraction and acid-heating extraction has a same lipid content which was lower than that of Soxhlet extraction.Acid-heating extraction was the most handy,and its ability to treat sample in a hour was the most powerful.Organic solvent extraction was less efficient.Acid-heating extraction was a simple and efficient method of fungi lipid extraction fitting to breed mutant strains that highly producting lipid and polyunsaturated fatty acids.

Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.
