Objectives To investigate the feasibility of the quantitative analysis parameters of dynamic contrast-enhanced MRI (DCE-MRI) in the diagnosis of prostate cancer and to correlate Ktrans, Ve and kep with histological grade (Gleason score) and serum prostate specific antigen (PSA). Methods MR examinations were performed in 38 patients confirmed by biopsy. ROI were drawn on areas of cancerous foci,noncancerous foci in the peripheral zone and central gland to measure the values of Krans, Ve and kep. The values of the three parameters in different tissue were compared with ANOVA. The correlations between the pharmacokinetic parameters and Gleason score, PSA were assessed with Pearson correlation. Results The Ktrans, Ve, kep values of cancerous foci were (0. 35 ± 0. 26 )/min, ( 0. 185 ± 0. 080 ), ( 1.42 ± 0. 53 )/min,respectively, while (0. 07 ± 0. 05 )/min, ( 0. 040 ± 0. 024 ), (0. 50 ± 0. 18 )/min for noncancerous foci in the peripheral zone and (0. 19 ±0. 06)/min, (0. 161 ± 0. 062), (0. 94 ±0. 25) /min for noncancerous foci in the central gland, respectively. The differences between the three parameters of cancerous foci,noncancerous foci in the peripheral zone and central gland were statistically significant ( F = 16. 267,44. 084, 36. 095, respectively; P ＜ 0. 01 ). No significant correlations were found between any parameter and either Gleason score or PSA (r =0. 279,0.069, 0. 109, -0. 175, -0.067,0. 137, respectively;P ＞0. 05). Conclusion Quantitative analysis parameters of DCE-MRI are feasible in diagnosing prostate cancer. They may be useful in differentiating prostate cancer from benign prostatic diseases.

Aim To investigate the skeletal effects of ginseng flower bud(GF)on osteopenia induced by D-galactose using histomorphometry and biomechanical properties.Methods Fifty three-month-old male Sprague-Dawley rats were randomly divided into five groups.Rats in NS group(NS)were treated with NS(5 mL·kg-1·d-1)by subcutaneous injection and daily oral gavage with vehicle as control.Rats in the other four groups were given D-galactose at the dose of 100 mg·kg-1·d-1 by subcutaneous injection.Solvent control was performed between NS and DG: gastric irrigation with distilled water of 10 mL·kg-1·d-1.Other groups were: CP was gastric irrigated with integrated medicine(stanozolol 0.54 mg·kg-1·d-1+piracetam 432 mg·kg-1·d-1),GF(L)with ginseng flower bud of 0.486 g·kg-1·d-1 and GF(H)with ginseng flower bud of 2.43 g·kg-1·d-1 for 14 weeks.The longitudinal proximal tibial metaphyseal(PTM),the fifth lumbar vertebral body(LVB)and tibial shaft(Tx)sections were performed undecalcifiedly and used for bone histomorphometric analysis.858 Mini Bionix materials testing system was used to analyze the biomechanic properties of right femur via three-point bending test.The left femur was dried and assimilated,whose bone calcium(Ca),phosphate(P)content and bone hydroxyproline content were tested.Results Compared with D-glagatose group,in PTM of D-galactose treated rats,the％Tb.Ar was increased both in GF(L)and GF(H)treated groups.While the Tb.Sp was decreased.％Oc.S.Pm and Oc.N/mm decreased in GF(L),and those in GF(H)were decreased as well.In Tx,％Ct.Ar was raised,while％Ma.Ar was decreased in GF(L)and GF(H).The elastic load of femur was increased.Conclusions Compared with DG group,there are significant differences in bone histomorphometry of Tx and PTM in all doses of GF,but no significant changes are detected in hydroxyproline,Ca,and P content of femur.

Objective:To study the prosthodontic design for the treatment of maxillary first molar mesio-lingual cusp defect with subfis-sue.Methods:A finite element model of maxillary first model,including mesio-lingual cusp defect with subfissue,periodontal support-ing tissue and a section of the maxilla was established by cone beam CT.Different prosthodontic designs for respective restoration and simulating different bite force were adopted,the Von Mises stress,maximum compressive stress and the crack distribution,J integral and the root displacement were analysed.Results:In the metal pile restoration model,the stress,JINT value and the equivalent stress and displacement of root were the smallest.With the increase of crack depth of the vertical and oblique fissue,the equivalent levels of stress (equivalent stress of J integral),the stress experienced by the dentin along with the peak of the maximum principal,increased signifi-cantly.Under 4 kinds of force direction and 3 repair methods,the equivalent stress peak value,J integral dentin stress,maximum prin-cipal stress peak value and dentin stress peak value of the cracks was 200 N,90°>200 N,45°>600 N,0°>200 N.Conclusion:High elastic modulus and all ceramic crown may lead to minimal equivalent stress,J integral,dentin equivalent stress and maximum principal stress.When subfissure is repaired,teeth fracture remains possible and any possible propagation may exist.The effect of later-al force on the crack and the dentin is greater than that of vertical force for crack expansion and tooth fracture.

Objective:To investigate the correlation between preeclampsia and thyroid dysfunction in pregnancy.Methods:107 early pregnant women with preeclampsia admitted to our hospital from Jan. 2017 to Jan. 2020 were all enrolled (observation group) . The observation group were in 6-34 gestational weeks, with an average parity of (1.67±0.35) times. In addition, 100 cases of normal pregnant women in the same period were selected as the control group. The control group were in 6-34 gestational weeks, with an average parity of (1.61±0.31) times. The two groups were compared at early, mid and late pregnancy in terms of thyroid function, and the correlation of preeclampsia and abnormal thyroid function was analyzed.Results:1. TSH levels in the observation group were (1.92±1.24) , (2.07±0.82) , and (2.30±1.23) mU/L in the first trimester, second trimester and third trimester, respectively, showing an upward trend. The difference between the two groups was statistically significant ( P=0.024) . FT4 levels of the observation group in the first trimester, second trimester and third trimester were (0.80±0.26) , (0.60±0.34) and (0.59±0.32) pmol/L, respectively, showing a decreased trend and the difference was statistically significant compared with those of the control group ( P=0.012) . 2. The incidence of hypothyroidism, TPOAb positive and reduced free tetraiodothyronine in the observation group was significantly higher than that in the control group ( P=0.001, 0.023, 0.005) . There was no significant difference in the incidence of hyperthyroidism or subclinical hypothyroidism between the two groups ( P=0.169, 0.846) . 3. Correlation analysis showed that preeclampsia was related to hypothyroidism, normal thyroid function with TPOAb positive and reduced free tetraiodothyronine ( P=0.000, 0.000, 0.000) . Conclusions:There are changes in thyroid function in pregnant women with preeclampsia. Hypothyroidism, positive TPOAb and reduced free tetraiodothyronine are closely related to the onset of preeclampsia.

Serum vitamin D level and vitamin D receptor (VDR) gene FokI polymorphisms were detected in 200 single full-term pregnant women who gave birth in our hospital during 2016 to 2018. The newborns with birth weight<2500 g were diagnosed as fetal growth restriction (FGR), there were 100 cases in FGR group and 100 cases in control group. The average level of vitamin D in pregnant women in FGR group was significantly lower than that of the control group [(30.1±10.9) vs. (36.1±15.8) nmol/L, P<0.05]. In the FGR group, the birth weight of infants in mother carrying ff genotype was significantly lower than that in mother carrying Ff and FF genotypes [(2073±90) g vs. (2242±122) g and (2349±96) g, P<0.05]. Pregnant women carrying Ff and FF genotypes had lower risk of FGR than those of carrying ff genotype (ORFf=0.31, 95％ CI: 0.17-0.76; ORFF=0.28, 95％CI: 0.11-0.46). The pregnant women with serum 25(OH)D level>30 nmol/L carrying F allele (FF+Ff) were set as reference, the risk of FGR in pregnant women with serum 25 (OH)D level ≤ 30 nmol/L carrying ff genotype was increased (OR=6.14, 95％CI: 2.13-13.23). The polymorphism of VDR gene FokI may be associated with the occurrence of FGR. In the case of vitamin D deficiency, the influence of ff genotype on FGR is more tangible.
