Objective To screen the 5 EV71 vaccine candidates which were isolated from MRC-5 cells to find one as the vaccine virus. Methods The ICR mother mouse were immunized by intraperitoneal injection with the 5 vaccine candidates which were made from monoclonal EV71 virus. Two weeks after booster immunization, the animals were allowed to mate, another booster was given after 2 weeks, and then attracted the milk mouse within 24 h with different types of virus by cranial cavity injection. The survival condition were recorded everyday, and the antibody titre(IgG) were detected by ELISA, the virus titre of intestine were detected by nest-PCR, and neutralizing antibodies were determined using a microassay with MRC-5 cells, and then the data were analyzed by SPSS16.0. Results The antibody titre of 5 virus immunized ICR mouse were improved with the increase in the immune times, and they got difference in neutralization capacity, the survival rate after fatal attract and the virus titre of the intestine. Conclusion It proved that the five vaccine candidates were different at the molecular level, cellular level and individual level. 123 strain was the best one in immunogenicity and immunoprotective property, which agreed with the vaccine requirement.

Objective:To analyze the repeatability of keratometry and astigmatism values measured by the OPD-Scan Ⅲ and the agreement of the parameters measured by OPD-Scan Ⅲ and Pentacam.Methods:A diagnostic test study design was adopted.Fifty patients (100 eyes) with refractive errors, aged from 21 to 35 years old, were selected from Second Affiliated Hospital of Nantong University and Lixiang Eye Hospital of Soochow University during August 2018.Spherical equivalent, astigmatim degree and axis were measured by Autorefraction.Corneal biometric measurements were measured three times continuously with the above two instruments.Keratometry values at the flat axis (K1), keratometry values at the steep axis (K2), astigmatim degree, axis, vector parameters J0 (Jackson cross cylinder at 0°or 180°) and J45 (Jackson cross cylinder at 45°) were recorded.Intraclass correlation coefficient (ICC) was used for repeatability analysis.Wilcoxon signed rank test, Spearman correlation analysis and Bland-Altman graphs were employed to analyze the comparability.This study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Lixiang Eye Hospital of Soochow University (No.SLER2018112). Written informed consent was obtained from each patient prior to any examination.Results:The ICC of K1, K2, astigmatism, astigmatic axis, J0 and J45 measured by OPD-Scan Ⅲ were all greater than 0.900; the ICC of the astigmatism measured by Pentacam was 0.896, and the ICC of the other parameters measured by Pentacam were greater than 0.900; The values of K2, astigmatism, J0 and J45 measured by OPD-Scan Ⅲ were greater than those measured by Pentacam, and the differences were statistically significant (all at P<0.05). The values of K1, K2, astigmatism degree, axis, J0 and J45 measured by OPD-Scan Ⅲ were positively correlated with those measured by Pentacam (r s=0.981, 0.982, 0.900, 0.737, 0.921, 0.703, all at P<0.01). The 95% agreement of limits (LOA) of K1, K2, astigmatism, axis, J0 and J45 measurement difference between OPD-Scan Ⅲ and Pentacam were -0.52-0.50 D, -0.39-0.59 D, -0.37-0.48 D, -17.29°-20.38°, -0.12-0.24 D and -0.22-0.28 D, respectively. Conclusions:OPD-Scan Ⅲ has high credibility in measuring corneal refractive power and astigmatism degree, but its 95% LOA of astigmatism axis is too large to be accepted clinically.

Objective To investigate the morphological changes in the sciatic nerve and the dorsal root ganglions (DRGs) and also gene expression in DRGs after non-freezing cold injury, and to explore the molecular mechanism of peripheral nerve cold injury and regeneration. Methods Twenty-four male Wistar rats were used. The sciatic nerve on one side was cooled to 4℃ for 2 h, and the sciatic nerve on the opposite side was exposed, but without cooling. Sciatic nerves and L4, L5 and L6 DRGs from both sides were harvested at the 1st, 2nd and 3rd week after cooling. Any pathological changes were observed using light and electron microscopy. Laser capture microdissection (LCM) was used to investigate the DRG neurons' gene expression. The array result was verified with RT-PCR for eight genes. Results Large fiber degeneration was obvious by the 7th day after cooling. Myelinated fiber regeneration had begun by the 14th day, so this time was chosen to explore the neurons' gene expression. Ninety-six genes and expressed sequence tags (ESTs) were up-regulated greater than 2 fold. Their proteins' functions were classified as adaptive response to external stimulus, apoptosis regulation, cell adhesion, immune and inflammation response,nerve regeneration, pain associated molecules, microtubule cytoskeleton, ion-channels, neurotransmitters and receptors, and neuropeptides. Conclusions A complex molecular mechanism is involved in cold injury and regeneration of the sciatic nerve, and many genes are involved. Large scale microarray analysis is a potent means to screen out related genes, thus suggesting future repair strategies.

Objective To study early changes in biochemical markers of bone turnover for prodicting the bone mineral density(BMD) response to alendronate therapy in Chinese men with osteoporosis. Methods Seventy-eight men aged 60 to 82 years with osteoporosis [mean age (69.8 ±11.8) years]were treated with alendronate sodium 70 mg/week for 12 months. Serum bone gla-protein (BGP) and serum pyridinoline-eross-linked earboxyterminal telopeptide of type I collagen (ICTP) level were measured by chemiluminescence (equipment is Roche E170). Serum BGP, ICTP and BSALP levels were measured before and 3 months and 12 months after treatment. BMD in lumbar spine and femoral neck were measured with dual energy X-ray absorptiometry (GE PRODIGY Inc. ) at L1-4 and at the left hip(total hip,trochanter,Ward's area and femoral neck)before and 12 months after treatment. Results After 3-months and 12-months treatment, the percent reductions of serum ICTP levels were 45.8% and 51.6%, serum BGP level 32.0% and 37.5%, serum BSALP level 35. 3% and 39.9% ,respectively. After 12-months treatment, the percent increase of lumbar BMD was 11.8%, femoral neck BMD 11.4 %. The percent reductions of serum ICTP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0.28, 0.295,P <0.05 and P<0.01)and of fermoral neck BMD at 12 months after treatment(r=0.262, 0.333, P<0.05 and P<0.01)respectively. The percent reductions of serum BGP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0. 322, 0.401,all P<0.01) and of fermoral neck BMD at 12 months after treatment (r=0.277,0.284, all P<0.05)respectively. The percent reductions of serum BSALP level at months 3 and 12 after treatment were positively correlated to the percent increase of lumbar BMD (r=0.133,0.231,all P<0.05) and of fermoral neck BMD at 12 months after treatment(r=0.248, 0.317, all P<0.01)respectively.Conclusions Early changes in biochemical markers of bone turnover rates can predict BMD response to alendronate in Chinese men with osteoporosis.

Objective To develop an ideal cultural method to amplify embryonic hepatic stem cells and inhibit their differentiation in vitro. Methods Suspension of ED 14 Fischer (F) 344 rat em-bryonic hepatic stem cells was prepared by collagenase digestion and mechanical disaggregation. Then cells were divided into two groups randomly. The cells in group 1 were seeded into type I collagen-coated plates by adherent culture while those in group 2 were seeded into soft agar medium by suspen-sion culture. After culture for 2 weeks, the morphology and ultrastructure of cells in both groups were observed and compared by inverted microscope and transmission electron microscope, respectivley.The expression of CD90. 1 and CD49F, the two specific stem cell surface markers, was tested by flow cytometry to manifest the establishment of embryonic hepatic stem cells. Alkaline phosphatase stai-ning was used to detect stem cell differentiation. Result Embryonic hepatic stem cells in group 2 were characterized by higher nucleus-cytoplasm ratio and less cell organelles, higher expression of CD90. 1 and CD49F, and stronger positive reaction for alkaline phosphatase staining compared with those in group 1. Moreover, the cells in group 1 showed significant differentiation features. Conclusion Em-bryonic hepatic stem cells cultured suspendedly in soft agar medium experience less differentiation than those adherently cultured in serum-added culture medium, and can proliferate and form clone ball with a specific stem cell feature.

Objective To compare dose-volume parameters for local failure in esophageal cancers treated by there-dimensional conformal radiotherapy (3 D-CRT) or intensity modulated radiotherapy (IMRT) with different target regions.Methods A total of 244 patients with esophageal cancer (including 127 patients with local recurrence and 117 without recurrence) underwent radical 3D-CRT and IMRT were enrolled in this study.Data including dose-volume parameters and clinical features were analyzed retrospectively.Results No statistically significant differences were found in the dose-volume parameters of different planning target regions between groups with local tumor recurrence and without recurrence (P > 0.05).In the elective nodal irradiation(ENI) group, neither the recurrence and the non-recurrence groups showed statistical differences in the dose-volume parameters (P > 0.05).While for the involved-field iradiation(IFI) group, the GTV-V60, CTV-V60, PTV-V60 of local recurrent group were significantly lower than those in the non-recurrent group (t =-2.08,-2.19,-2.08, P < 0.05).In the ENI group, radiated doses of GTV, CTV and PTV as well as dose-volume of PTV were significantly higher than the IFI group (t =1.97-3.12, P < 0.05).For patients with a esophageal GTV less than 30 cm3 but without concurrent chemotherapy, radiated dose of CTV-D98% , CTV-D95% in the recurrent group were significantly lower than in non-recurrent group (t =-2.24--2.07, P < 0.05).Conclusions Elective nodal prophylactic radiation of esophageal carcinoma could provide greater volume and doses of GTV, CTV and PTV to prescribed target regions, which may decrease local recurrence.Greater efficiency can be obtained when the primary lesion of the esophageal cancer is smaller or at an early stage, and concurrent chemotherapy is not given.
