Objective To establish neonate rate models induced by high-fat diet so as to explore the effect of high-fat diet before and during pregnancy on growth and serum insulin-like growth factor-1 (IGF-1) level in neonate offspring.Methods Forty female SD rats were divided into high-fat group and control group that were fed with 35% high-fat diet and standard chow,respectively.After 8 weeks,8 rats from each group were euthanatized for liver pathology and the other female rats were mated with male rats and fed continuously with 35% high-fat diet and standard chow throughout gestation,respectively.Offspring from both groups were studied within 24 hours after birth.Their birth weight and body length (from apex nasi to end of tail) were measured.Enzyme-linked immunosorbent assay was used to detect serum IGF-1 level.Serum biochemical indexes were tested by biochemical analyzer.Liver pathologic changes were observed under the light microscope.The expression of IGF-1 in liver samples was detected by Western blot.Results 1.Rats in the high-fat group showed a significant less birth weight and shorter body length compared with those in the control group(all P < 0.05).2.The level of serum IGF-1 of offspring in the high-fat group decreased by 20.1% in comparison to offspring in the control group,but there was no significant difference between the 2 groups (P > 0.05) because of the limited sample sizes.3.The aspartate transaminase(AST) of offspring in the high-fat group increased compared with those from control group(P < 0.05),while other serum biochemical indexes between the 2 groups showed no significant differences(all P >0.05).4.Fatty degeneration could be found in livers of both dams and offspring in the high-fat group under light microscope,while the samples of both dams and offspring from the control group all showed normal.5.The IGF-1 expression in livers of offspring from high-fat group increased in comparison to that from control group(P < 0.05).Conclusions A maternal high-fat diet before and during pregnancy decreases the birth weight and body length of offspring in utero,which may be associated with the decreased IGF-1.However,the pathogenesis of decreased IGF-1 in this study can not been found.Further study is needed to clarify the mechanism of intrauterine growth retardation induced by high-fat diet.

Objective To investigate the feasibility of Antituberculotic?loaded bone cement (ATLBC) prepared by mix?ing the anti?TB drugs Rifampicin (RFP), Isoniazid (INH), Pyrazinamid (PZA), Moxifloxacin (MFX) with Palacos R PMMA bone cement in Total Joint Arthroplasty treatment for Joint Tuberculosis. Methods Forty grams of Palacos R bone cement powder without antibiotics was mixed with 1 or 2 grams of RFP, INH, PZA and MFX respectively. According to ISO 5833:2002 stan?dard, 8 groups of ATLBC standard test specimen were prepared as experiment group and Palacos R PMMA bone cement with?out antibiotics was prepared as control group. Physical properties (such as the average dough time, curing time, maximum tem?perature), mechanical strength (such as the compressive strength, the bending resistance strength, the modulus of elasticity) and the concentrations of eluant drug in different time points of ATLBC were detected. Results In RFP (1 g), RFP (2 g), INH (1 g) and INH (2 g) group, the average dough time and curing time were longer than those in control group, which exceeded the standard scope of ISO, while the average maximum temperature was significantly lower than that in control group. The INH ( 1 g) group and INH (2 g) group hardened after mixing for 14 days. The RFP (1 g) group and RFP (2 g) group hardened after mixing for 30 days. Twenty minutes after mixing and hardening, the compressive strength, bending resistance strength and modulus of elastic?ity were significantly lower than the specified values of ISO standard. The physical properties and mechanical strength in PZA ( 1 g) group, PZA (2 g) group, MFX (1 g) group, MFX (2 g) group and control group were in accordance with the specified values of ISO standard, and they hardened after 20 minutes. In RFP (1 g) group, RFP (2 g) group, INH (1 g) group, INH (2 g) group, PZA (1 g) group, PZA (2 g) group, MFX (1 g) group and MFX (2 g) group, the concentration of eluant could maintain for 3 days, 7 days, 90 days, 90 days, 45 days, 60 days, 60 days and 60 days respectively. Conclusion RFP and INH mixing with Palacos R PMMA bone cement can hinder the aggregation of bone cement so they are unsuitable for preparing ATLBC. PZA and MFX mixing with Palacos R PMMA bone cement do not affect the physical properties of bone cement, with excellent mechanical strength and elu?tion properties. Because the minimal inhibitory concentration of PZA is higher and its antimicrobial activity maintains shorter time, while MFX maintains longer time in antimicrobial activity, it's more suitable for the preparation of ATLBC.

Objective :
To classify the furcation involvement (FI) of endodontically treated mandibular first permanent molars based on cone beam computed tomography (CBCT), provide reference for individualized treatment of FI.
Methods:
CBCT images of the FI of 164 endodontically treated mandibular first permanent molars from 163 patients in Nanjing Stomatological Hospital, Medical School of Nanjing University were collected retrospectively. On the CBCT images, the shape and extent of periapical and periodontitis bone resorption, the thickness of residual dentin in the pulp floor and root canal wall, and the periodontal bone resorption of the complete dentition were evaluated. The FI was classified into periodontal, periapical, perforated and mixed types.
Results:
Among the 164 FIs of endodontically treated mandibular first permanent molars, the periapical type was the most common (41.5%), followed by the mixed type (26.2%), perforated type (18.3%), and periodontal type (14.0%). Among the 68 periapical-type FIs of endodontically treated mandibular first permanent molars, 48.5% were proper root canal filling, 44.1% were insufficient filling and 7.4% were overfilling. Among the 43 mixed-type FIs, the periodontal mixed periapical type was the most common (72.1%).
Conclusion
Detailed evaluation and classification of furcation involvement could be performed using CBCT images; therefore, the study has guiding significance for clinical treatment.
