Thinning and atrophy of sclerotic tissues play an important role in the development of high myopia. High myopic eyes had the thickest sclera at the posterior pole and the thinnest sclera at the equator. Most clinical studies found that scleral thickness was negatively correlative with the axial length. Patients complicated with posterior staphyloma had even thinner sclera, and its height was negatively related with the scleral thickness. At present, the main measurement methods for scleral thickness of high myopic eyes include histological measurement, enhanced depth imaging optical coherence tomography (OCT), and swept-source OCT. Following the development of OCT technique, it gradually becomes feasible to carry out studies on sclera thickness in mildly and moderately myopic populations, which is helpful to illuminate the mechanism of action of sclera on the onset and progression of high myopia.

Objective To investigate the expression pattern of hypoxia inducible factor-1?(HIF-1?) in fetal vertebra development of the mouse. Methods The development of mouse fetal vertebra was observed dynamically,and the expression of HIF-1? mRNA at various stages was also detected by reverse transcription-polymerase chain reaction. Results The cartilaginous spine column began to form at E13.5.The primary ossification center was observed at E15.5,then the osteogenesis expanded and extended to both sides.HIF-1? mRNA began to express at E13.5,and more significantly at E14.5(P

Objective To study the effects of preterm birth, infection, pathological jaundice and asphyxia on neonatal thyroid function. Methods From April 2012 to April 2014,neonates within 7 days after birth admitted to the neonatal department of our hospital were recruited. The neonates with one or more of the 4 aforementioned conditions were assigned to the observation group; the full-term newborns without any diseases to the control group. 2 ml of venous blood from each patient was collected 5-7 days after birth to determine the levels of serum free iodine thyroid original glycine ( FT3 ) , free thyroxine ( FT4 ) and thyroid stimulating hormone ( TSH ) . The thyroid function of newborns in the observation group were re-examined after recovery, and compared among different groups and conditions. Results A total of 220 newborns were recruited in the observation group and 34 in the control group. FT3 in the observation group was significantly lower than the control group ( P＜0. 05 ) . As for FT4 and TSH, no statistically significant differences existed between the two groups ( p＞0. 05 ) . FT3 and FT4 in neonates with severe infection were significantly lower than mild infection ( P＜0. 05 ) . FT3 in the preterm group with gestational age ( GA ) ≤32 weeks was significantly lower than GA＞32 weeks, and FT3 in the jaundice group, serum bilirubin level ≥ 342 mol/L group significantly lower than ＜342 mol/L group (P＜0. 05) . In the observation group, the re-examined FT3 concentration was significantly higher (P＜0. 05) than the result tested 5-7 days after birth while FT4 and TSH didn′t show significant differences. And no significant differences existed between the observation group and the control group in re-examined thyroid functions ( P＞0. 05 ) . The multivariate analysis showed that GA, pathological jaundice, infection and asphyxia were associated with FT3 concentration 5-7 days after birth (P＜0. 05), while the delivery method and gender not (P＞0. 05). Conclusions The main effect of preterm birth, infection, pathological jaundice and asphyxia on thyroid function was to decrease FT3 temporarily. Severe infection might decrease FT4 temporarily. However, the thyroid function would return to normal with recovery.

Atomic force microscope(AFM) has one important feature that it is used to scan the samples with non-modified and modified probes to obtain sample appearance,and force-distance curve at certain point,based on which the adhesion,bond force and mechanical properties of the sample can be obtained.Until recently,the application of the AFM to measure the mechanical properties of biological sample is very extensive,which is significant in biomedicine and clinical medicine.This paper introduced the force curve theory of AFM,and reviewed the application of AFM to measure the mechanical properties of biological sample including elasticity,adhesion,stiffness,the interaction between antibody and antigen of the cell.In addition,we prospected the application and development of AFM to analyze cell mechanical properties.

BACKGROUND:Adolescent idiopathic scoliosis is a common disease that can affect physical appearance of adolescents in the clinic at present. However, there are lacks of studies on coronal plane imbalance after fixation using Logistic regression equation at present.
OBJECTIVE:To investigate the reasons for coronal plane imbalance after fixation in patients with Lenke type II adolescent idiopathic scoliosis.
METHODS:141 cases of Lenke type II adolescent idiopathic scoliosis admitted by Department of Spinal Surgery of the First Affiliated Hospital of Xinjiang Medical University in China from January 2001 to November 2012 were chosen as subjects. Multivariate single factor and multiple-factor Logistic regression were performed. Risk factors for the coronal plane imbalance after fixation in adolescent idiopathic scoliosis patients were screened, and predictive models were established.
RESULTS AND CONCLUSION:Coronal plane imbalance occurred in 30 of the 141 patients, accounting for 21.28%. For Lenke type II adolescent idiopathic scoliosis patients, preoperative apical vertebral Nash-More rotation level 3-4, Risser grade 4-5, major curve correction rate/flexibility>1, lower thoracic Cobb angle>70° were vulnerable to postoperative coronal plane imbalance. Multivariate logistic regression showed that vertebral rotation, Risser grade, major curve correction rate/flexibility, lower thoracic Cobb angle were independent risk factors for postoperative coronal plane imbalance in Lenke type II adolescent idiopathic scoliosis patients. The predictive model was Y=1/[1+exp(-1.182X 1+1.228X 2+1.671X 3-0.71X 4+0.407)].

Objective To understand the genetic characteristics of Enterovirus 71 ( EVT1 ) circu-lating strains of Guangdong province in 2008. Methods We isolated an EV71 strain from the fatal case of the hand, foot and mouth disease during an epidemic of Guangdong in 2008. Its complete genome was se-quenced and analyzed comparatively. Results The results showed that the full length of EV71 GDFS-3 ge-nome( not including poly A tail ) is 7405 bp. No insertion or deletion is detected in the coding region. There are several insertions and deletions in 5'and 3'UTR. Phylogenetic analysis of GDFS-3 and reference strains showed GDFS-3 strain shares the highest nueleotide homology with TW984 strain(96.0% ) but low homology with SIN5865, MS and BrCr( about 81.0% ). GDFS-3 strain also shares the highest amino acid homology with TW984 strain(99.0% ). It clustered with reference strains of CA subgenotype in the phylogenetie tree. The nucleotide identity with CA reference strains is 91.0% -95.0%. Conclusion The phylogenetic analysis based on the entire genome demonstrates that GDFS-3 strain has the nearest genetic relationship with TW984 strains ( isolated in 2004). GDFS-3 may belong to the same subgenogroup ( CA ) with Taiwan predominant strains. Otherwise,Some mutations in 5'UTR of EV71 may play the very important role in heightened viru-lence.

Objective To investigate the correlation between 24 h urinary protein quantitation and pregnancy outcome in patients with pre-eclampsia.Methods A total of 332 pre-eclampsia patients were selected in Tongji Hospital from January 2014 to December 2016.The patients were divided into microalbuminuria group(24 h urinary protein quantification ＜ 0.3 g,n =46),mild proteinuria group (0.3 g ≤ 24 h urinary protein quantification ＜ 2.0 g,n =98),moderate proteinuria group (2.0 g ≤ 24 h urinary protein quantification ＜ 5.0 g,n =71) and severe proteinuria group(24 h urinary protein quantification ≥ 5.0 g,n =117) according to the results of 24 h urinary protein quantification.The pregnancy outcomes were compared between the four groups.Results The 24 h urinary protein quantification and the serum creatinine,urea nitrogen,uric acid levels in the mild proteinuria group,moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the microalbuminuria group (P ＜ 0.05).The 24 h urinary protein quantification and serum urea nitrogen,uric acid levels in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in serum creatinine level between the two groups (P ＞ 0.05).The 24 h urinary protein quantification,serum creatinine,urea nitrogen and uric acid levels in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the gestational week was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The 24 h urinary protein quantification in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the gestational week and serum creatinine,urea nitrogen,uric acid levels between the two groups (P ＞0.05).There was no significant difference in the rates of cesarean section and spontaneous labor between the four groups (P ＞0.05).The rate of induced labor in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the mild albuminuria group and the microalbuminuria group (P ＜ 0.05).There was no significant difference in the rate of induced labor between the mild proteinuria group and the microalbuminuria group (P ＞ 0.05).There was no significant difference in the rate of induced labor between the severe proteinuria group and the moderate proteinuria group (P ＞ 0.05).The incidence of complications in microalbuminuria group,mild proteinuria group,moderate proteinuria group and severe proteinuria group was 30.43％ (14/46),47.96％ (47/98),74.65％ (53/71) and 74.36％ (87/117) respectively;the incidence of complications in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the microalbuminuria group and the mild albuminuria group (P ＜ 0.05),but there was no significant difference in the incidence of complications between microalbuminuria group and mild albuminuria group (P ＞ 0.05),there was no significant difference in the incidence of complications between the moderate proteinuria group and the severe proteinuria group (P ＞0.05).The incidences of premature birth and neonatal asphyxia in the mild proteinuria group were significantly higher than that in the microalbuminuria group (P ＜ 0.05),and the body mass of the neonates was significantly lower than that in the microalbuminuria group (P ＜0.05),but there was no significant difference in the perinatal mortality rate and the incidences of fetal growth restriction(FGR) and poor neonatal resuscitation between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and the perinatal mortality in the moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and neonatal body mass was significantly lower than that in the mieroalbuminuria group (P ＜ 0.05).The incidences of FGR,premature birth and poor neonatal resuscitation and perinatal mortality in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the neonatal body mass was significantly lower than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in the neonatal asphyxia incidence between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and perinatal mortality in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the body mass of the newborns was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The incidence of neonatal asphyxia in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the incidences of FGR,premature birth,poor neonatal resuscitation,perinatal mortality and neonatal body mass between the two groups (P ＞ 0.05).Conclusions The of 24 h urinary protein quantitation is closely related to the pregnancy outcome in patients with pre-eclampsia,the 24 h urinary protein quantification should be regularly detected in the patients with pre-eclampsia.When the urinary protein quantitation is more than 2.0 g,the incidences of maternal complications and poor prognosis of the perinatal infants is significantly higher,but the boundary value of the 24 h urinary protein quantitation for the diagnosis of severe pre-eclampsia still needs further large sample study.

OBJECTIVETo observe dynamically the development of fetal long bone and detect the expression and distribution of HIF-1alpha,to investigate the expression pattern and possible effects of hypoxia inducible factor-1alpha (HIF-1alpha) in fetal long bone development of mouse.

METHODSE12.5, E13.5, E14.5, E15.5, E16.5 and E17.5 pregnant C57BL6 mice were sacrificed. After sacrifice, the embryos were delivered by caesarean section. The development of fetal long bone was dynamically observed by stereoscopic microscope, and the distributional expression of HIF-1alpha protein was detected by using method of immunohistochemistry. The expression of HIF-1alpha mRNA and osteoblast marker gene at various stage were also detected by using methods of reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSThe cartilaginous long bone began to form and joints outline arised at E13.5, then the primary ossification center was observed at E14.5, showing opaque ossification under stereoscopic microscope,and then the osteogenesis expanded and extended to both sides. Immunohistochemistry demonstrated lots of HIF-1alpha protein positive chondrcytes in the center of primary ossification at E14.5, then they decreased dramatically. HIF-1alpha mRNA expressed at high level from E13.5 to E15.5, and then decreased to low level.

CONCLUSIONFetal long bone development pattern appeared to be endochondral osteogenisis process, existing hypoxia microenviroment may increase HIF-1alpha mRNA expression and thus initiate the cascade of endochondral osteogenisis.
