[Summary] The theory of fetal origins of adult disease (FOAD) is now widely accepted by researchers who hold the opinion that adult degenerative and metabolism diseases have close relationship with the environment of fetal development inside and outside the womb. Some studies have proved that maternal hypothyroidism can negatively affect the glucose metabolism of their offsprings. However, the whole mechanism is not clear yet. Insufficient thyroid hormone during pregnancy was proved to slow down the formation of fetal pancreatic cytoskeleton, to decrease the proinsulin gene transcription, and to modulate series of cytokines and enzymes which are related to glucose dependent insulin secretion. Thyroid hormone receptor is also considered to be partially responsible for the relation between low thyroid hormone and β cell insufficiency. However, more studies in vivo should be carried out to prove this hypothesis. Epidemiologic studies have suggested that type 2 diabetes and low birth weight can be different phenotypes of the same genotype. The definite mechanism of maternal hypothyroidism in influencing fetal β-cell function should be studied by further investigation.

Objective:To investigate influences of bicortical anchora ge on the values of natural frequency of dental implants. Methods: Using the commercial code of SolidWorks, 3-D models of a screw-shaped dental i mplant and a mandibular bone segment were generated. After the 3-D implant-bon e complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were comp uted. Results:Bicortical anchorage increased the buccolingual na tural frequencies and the axial natural frequencies of the implants by a maximu m of 13.77% and 107.40% respectively. The apical anchorage depth in the cortical bone had an insignificant effect on further increase of implant stability. Conclusion:Bicortical anchorage can increase the stability of dental implants, especially in the axial direction.

Thyroid diseases during pregnancy are highlighted in recent decade by both endocrinologists and gynaecologists.Hyper-and hypothyroidism accompanied with pregnancy may cause side effects on maternal and fetal health,increase the incidence of obstetric complications and impair the development of the fetal nervous system.It is widely accepted that subclinical thyroid dysfunction such as subclinical hypothyroidism,hypothyroxinemia,and thyroid autoimmunity may result in adverse obstetric outcomes.A very crucial work is going on to set up trimester special reference of thyroid function in each clinical laboratory.

Objective To investigate the exercise performance in maintenance dialysis patients,and analyze its correlative factors.Methods Maintenance dialysis patients admitted in Tongji Hospital of Shanghai from December 2014 to March 2015 were enrolled,with their baseline data and biochemical measurement being collected.The anthropometric indexes including arm circumference,triceps skinfold,waist circumference and hip circumference were detected.The exercise activity was assessed by hand grip test,timed up and go test (3mTUG) and five times sit-to-stand test (FTSST).Patients were divided into fast group (3mTUG≤12 s) and slow group (3mTUG ＞ 12 s).Univariate and multivariable analyses were used to evaluate the factors influencing exercise performance in maintenance dialysis.Results There were 121 patients enrolled:62 on peritoneal dialysis and 59 on hemodialysis,76 men and 45 women.Patients' average age was (61.6± 13.0) years and median dialysis age was 31.7(12.3,69.0) months.There was no statistical difference between fast group (n=80) and slow group (n=41) in gender,dialysis method,dialysis age,body mass index (BMI),arm muscle area (AMA),waist-hip ratio (WHR),hemoglobin (Hb) and total cholesterol (TC).Patients in fast group were younger,had higher serum albumin,prealbumin,serum phosphate and iPTH,and less prevalence of diabetes than those in slow group.In exercise activity,patients in fast group had better performance in handgrip,3mTUG and FTSST (all P ＜ 0.05).Univariate analysis showed that,handgrip was correlated with sex (male),AMA,BMI,age,diabetes,serum phosphorus and TC;scores in FTSST was correlated with age,BMI,diabetes,WHR,dialysis method,dialysis age,prealbumin and serum phosphorus;scores in 3mTUG was correlated with age,diabetes,WHR,dialysis method and dialysis age,prealbumin,serum phosphorus and iPTH (all P ＜ 0.05).Multiple stepwise regression analysis showed that sex (male),age,AMA and diabetes were independently correlated with handgrip in dialysis patients (all P ＜ 0.05);age,dialysis method,BMI and diabetes were independently correlated with scores in FTSST (all P ＜ 0.05);age,dialysis method,diabetes and WHR were independently correlated with scores in 3mTUG (all P ＜ 0.05).Conclusions The exercise performances of patients on maintenance dialysis are impaired.Age and diabetes are independent factor associated with the exercise performances of patients on maintenance dialysis.AMA is independently associated with upper limb movement,and dialysis method,BMI and WHR are independent factors associated with lower limb movement in dialysis patients.

Objective To analyze the effect of duloxetine on S100B and signal pathway ERK1/2-NF-κB expression in hippocampus in depression rat.Methods Chronic unpredictable mild stimulation was used to establish depressive model rats (n=50).They were randomly divided into no-intervention group (n=10),different treatment time of duloxetine group (C,D,E,F group,10 rats in each group)and then 10 normal rats were selected as control group.Behavior tests including open-field test and the saccharine preference test were used to test the behavioral change of rats after 28 days intragastric administration.Western blot was used to detect S100B,t-ERK1/2,pERK 1/2,t-NF-κB and pNF-κB expression in hippocampus.Results In open-field test,the crossing score,rearing score and latency of the rats in E,F group were (69.68± 14.61) and (70.66± 11.53) score,(20.94 ± 10.92) and (20.32±8.85) score,(1.1±0.4)s and(1.0±0.4) s respectively,and showed no significant difference with those of control group ((71.19±12.08) score,(20.42±8.76) score,(1.0±0.3)s) after 28 d intragastric administration (P＞0.05),while the level score,vertical score were significantly higher than those in depressive model (P＜ 0.05).In the saccharine preference test,the rats in E,F and control group exhibited increased saccharin preference compared with depressive model rats (P＜0.05).The rats in E,F and control group exhibited increased S100B,pERK1/2 and pNF-κB expression in hippocampus compared with depressive model rats (P＜0.05).Conclusion Duloxetine improves the behavioral ability of depression rat and exerts effect after 2 weeks.The ERK1/2-NF-κB signal pathway in hippocampus may participate in this mechanism.

Objective To evaluate the indications and clinical efficacy of the different surgical methods for lumbosacral tuberculosis.Methods 112 patients suffering from lumbosacral tuberculosis from January 1998 to October 2011 were reviewed retrospectively.Based on American Spinal Injury Association (ASIA) grading system,31 case was classified as grade C,32 as grade D and 49 as grade E.The affected locations were L5,S1 in 66 cases,L4-S1 in 32,and L5-S2in 14 cases.41 cases (posterior group) underwent posterior pedicle screw instrumentation,debridement and allograft; and 38 cases (anterior group) underwent one-stage anterolateral debridement plus allograft and internal fixation.33 (posterior-anterior group) cases experienced posterior pedicle screw instrumentation and anterior debridement and allograft.All cases underwent routine support and anti-tuberculosis treatment before and after operation.The change of erythrocyte sedimentation rate (ESR),signs of tuberculosis activity,graft fusion,neurological recovery and correction of deformity were evaluated in follow-up and compared among three groups.Results The average operating time in posterior,anterior and posterior-anterior group was (150±22) m in,(140± 18) min,(180± 1 8) min respectively.ESR and C-reactive protein (CRP) were recovered to normal 3 months post surgery.The quality of life total score of lumbosacral tuberculosis patients was very low (55.54 ± 9.23).After surgery and drug treatment,the total score and each dimension scores of the SF-36 were significantly improved.Postoperative ASIA classification and 1umbosacral angle were significantly improved.Tuberculosis recurrence occurred in three cases,fixation loosening in two cases,fixation fracture in one case,and all above cases were cured after revision surgery.The others all were cured and bone graft fusion was determined.Conclusion The quality of life of lumbosacral tuberculosis patients were impacted seriously,and which could be significantly improved with surgical intervention.According to the patient MRI,CT characteristics,surgical approach selection was based on lesion location.Effective internal fixation was based on the extent of damage in bone structure and anatomical characteristics.Following above principles,satisfactory clinical results could be achieved.

Objective To research the visualization of congenital heart disease by three-dimensional echocardiographic(3DE) virtual endoscopy(VE) system. Methods Datasets.from 10 healthy children and 22 patients with congenital heart disease were collected (10 patients with atrial septal defects, 6 patients with ventricular septal defects and 6 patients with tetralogy of Fallot). 3DE heart models were reconstructed by virtual reality computing techniques and visualization in scientific computing techniques. The VE system was programmed under the C++ 6.0 language condition,the visualization toolkit (VTK) platform was employed to carry out the graphics and visualization utilities. The virtual eye can move along the navigation paths in the heart by manual camera movements. Results The VE can provide special information in aspects of intracardiac anatomy, The visible heart models show precisely complex anatomy structure and spatial relationships. 3DE intracardiac endoscopic imaging can thus be visualized and navigated successfully by the VE system. Conclusions 3DE VE is a new system for the visualization of congenital heart disease.
