Objective To follow up the changes of postnatal cardiac sizes and function in infants of mothers with gestational diabetes mellitus (GDM). Methods Eighteen GDM mothers with euglycemia (GDM group) and 24 gestational age-matched normal pregnant women (control group),having prenatal examination and delivered in Women's Hospital of Fudan University from January to August in 2007, received fetal echocardiographic examination in late pregnancy. Infants of these GDM mothers and 24 age-matched healthy infants of normal pregnancy (control group) received sonographic follow up. Cardiac sizes and function were evaluated and compared. Results At birth, there were six (33.3%) infants of large for gestational age (LGA) and 12(66.7%) appropriate for gestational age(AGA) in GDM group, while in the control group, there were two LGA (8. 3%) and 22(91.7%)AGA infants (x2 =3. 840, P= 0. 05). Both the interventricular septum and left ventricular walls in GDM fetuses were thicker than in control fetuses (P ＜ 0.05). No increase in the thickness of ventricular walls was observed till infantile period. However, the end-systolic thickness of left ventricular walls in LGA infants was still larger than in control infants [(4.55 ± 0.37) mm vs (4. 13±0.39)mm, P＜0. 05], and end-diastolic left ventricular long-diameters were also larger [(37. 3±2.3) mm vs (34.6±2.6) mm] (P＜0. 05). In GDM fetuses, the peak velocities of aorta and pulmonary artery and left cardiac output were higher than in the controls (P＜ 0. 01 ), and right/left cardiac outputs ratios were lower (1.198±0.206 vs 1. 430±0. 321, t= -2.668,P=0. 011). Till infantile period, only right/left cardiac outputs ratios in AGA infants of GDM group were larger than in controls (P＜0. 05). GDM fetuses' left atrial shortening fraction and tricuspid E/A ratios were smaller (P＜0. 05). In infantile period, only left atrial shortening fraction in GDM infants was still smaller than in controls (0. 356 ± 0. 040 vs 0. 386 ± 0. 041, t = - 2. 332, P = 0. 025). Left and right ventricular Tei index in GDM fetuses were 0. 482±0. 129 and 0. 414±0. 094, both larger than those of control fetuses (0. 309 ± 0. 074 and 0. 283 ± 0. 072) (t = 5. 075 and 5. 129, P = 0. 000 ). Till infantile period they both became significantly lower and no differences were found among LGA, AGA and control infants. Conclusions The cardiac sizes and function at 2-3 months of age, in infants of GDM mothers with good glucose control, became better than that in uterus.

Objective: To establish an HPLC method for the simultaneous determination of eight components in Tibetan medicine Zuozhudaxi, and improve the standard of HPLC test. Methods: The HPLC analysis was performed on a Kromasil C18 column (250 mm×4.6 mm, 5 μm). The column temperatrue was set at 30℃. A mixture of methyl alcohol-0.05% phosphoric acid aqueous solution was used as the mobile phase, gradient eluted with the flow rate at 1 mL/min, and detected by different UV wave lengths, i.e. 225 nm for gallic acid, benzoic acid, kaempferol, costunolide, and dehydroepiandrosterone costunolide, 352 nm for chlorogenic acid, and 445 nm for crocin I and crocin II. Results: The eight components were well separated with ideal linear correlations. The average recoveries were in the range of 97.13%-101.42%. The contents of the eight components between two manufactures were different. PLS-DA loading plot of the samples showed that gallic acid, benzoic acid, kaempferol, dehydroepiandrosterone costunolide, and crocin II were the main components which made contributions to the quality of Zuozhudaxi. Conclusion: The method is reliable, stable, accurate, and reproducible for the quantitative determination and quality control of Zuozhudaxi.

BACKGROUND:The auditory ossicle chain reconstruction is stil an important method to treat conductive deafness. Although a great variety of materials have been applied, the blood supply of otosteon after the implantation is ignored. Moreover, there is no real bone formed.
OBJECTIVE:To observe the angiogenesis of vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold which is implanted into the otocyst of guinea pig.
METHODS:Total y 60 guinea pigs were randomly divided into experimental group (vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold), col agen I control group (col agen I modifiedβ-tricalcium phosphate porous scaffold) and blank control group (β-tricalcium phosphate porous scaffold). The guinea pigs were executed under anesthesia at weeks 1, 2, 3, 4 respectively. The surface of scaffolds was observed by scanning electron microscopy. The angiogenesis of scaffolds were observed by hematoxylin-eosin staining and CD34 immunohistochemistry staining, and then the microvascular density was counted. The osteogenesis of the scaffolds was observed by toluidine blue staining.
RESULTS AND CONCLUSION:Endothelial cel proliferation and lumen formation could be observed after 1 week in the experimental group, and the angiogenesis reach the peak after 3 weeks with traffic branches formedbetween micropores. In the other two groups, the lumen formed at 2 weeks but no traffic branches were visible. The sprouting of new blood vessels in the pores were observed more in the experimental group than the other two groups (P<0.05). The adherence and proliferation of cel s could be examined in the surface and pores of the scaffold by scanning electron microscope. After 4 weeks, the osteogenesis could be observed by toluidine blue staining, especial y in the experimental group. These findings suggest that the vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold can realize an effective vascularization in the environment of guinea pigs’ middle ear. What’s more, the scaffold also can promote bone formation.

Objective To investigate the expression of peroxisome proliferator-activated rec eptor γ (PPARγ) and glucokinase (GK) induced by Wnt signaling pathway in mice NIT-1 β-cells,and to explore the interaction between PPARγ and Wnt signaling pathways.Methods Recombinant Wnt3a protein was applied to NIT-1 beta-cells to activate Wnt signaling pathway.The expression of PPARγ was determined by real-time PCR and Western blotting.The expression of GK was determined by real time PCR.Results Wnt3a rapidly activated Wnt/β-catenin/TCF signaling pathway,and increased PPARγ and GK mRNA expression by 41.2％ and 65.0％ in NIT-1cells,with PPARγ protein expression increasing by 97.8％ (P＜0.01).These effects were abrogated by Wnt and PIK3 inhibitors,dickkopf 1 and wortmannin treatment (P＜ 0.01).Conclusions PPARγ and GK can be upregulated by Wnt singnaling,and the effects might partially be PI3K-dependent.

AIM: To evaluate the effects of interfer ?-2b (IFN ?-2b ) on atherosclerosis(AS).METHODS: Thirty normal male rabbits were randomly divided into five groups:normal control group(NC group, n= 6), atherosclerosis group(AS group, n =6),virus (herpesvirus Ⅰ,HSV-Ⅰ)infected atherosclerosis group(V group, n= 6), interferon (interferon ?-2b) intervented atherosclerosis group (IFN-Ⅰgroup, n= 6),interferon intervented and virus infected atherosclerosis group (IFN-Ⅱ group, n= 6). Serum lipids were measured and the thoracic aortas were sampled for histopathological, immunohistochemical and in situ hybridization study. RESULTS: The aorta atherosclerosis areas of NC, IFN-Ⅰ and IFN-Ⅱ groups were lower than that of AS group significantly, respectively, and the area of AS group was lower than that of V group ( P

AIM: To study the effect of torsional mode phacoemulsification on cornea in patient with age-related cataract.METHODS: Totally 161 age-related cataract patients (196 eyes) were assigned randomly to phacoemulsification by torsional mode(Group A) or conventional ultrasound mode (Group B) in our hospital from January 2012 to December 2014.The intraoperative data of effective ultrasound time(UST)and effective cumulative dissipated energy(CDE) were recorded.Postoperative outcomes and the change of the best corrected visual acuity(BCVA),corneal edema degree(CED),central corneal thickness(CCT) and endothelial cell count were also recorded and compared.RESULTS: For grade Ⅰ,Ⅱ,Ⅲ and Ⅳ nuclear density,the mean UST and mean CDE were significantly lower in Group A.The average BCVA of Group A was better than Group B at 1 and 7d after surgery.But at 30d postoperative,there was no statistical difference between these two groups(P>0.05).The corneal clarity and the mean change of central thickness showed significantly less corneal edema in Group A than Group B in 1 and 7d postoperatively.This difference was no longer found significantly at 30d after surgery(P>0.05).At 7 and 30d postoperative,the endothelial cells in Group B were lower than in Group A.CONCLUSION: By reducing the effective UST and CDE intraoperatively,the main effect of torsional mode phacoemulsification on cornea shows less damage to endothelium cells,and patients get better prognosis.But the damage to cornea by torsional mode phacoemulsification isn`t fundamentally solved.
