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.

Background Despite psycho-oncological concerns and studies having thrived these past decades,sparse reports illustrate to what extent Chinese cancer patients are involved and influenced by comorbid mental health problems.To investigate the mental health condition of cancer patient,as well as its possible impacts on prognosis,the first large-scale survey was performed in the west of China.Methods For standardizing and facilitating the assessment of mental illness in inpatients with cancer,a multidisciplinary rating flow was designed and established.On the basis of this system,between May 1st and 31st 2009,2279 cancer inpatients from nine medical centers received preliminarily screening executed by oncologists using screening scales Mental Health Screening Questionnaire (MHSQ),Zung self-rating depression scales (SDS),Zung self-rating anxiety scale (SAS),and posttraumatic stress disorder checklist-civilian version (PCL-C).Further analyses of the ones screened positively were conducted by psychiatrists applying corresponding symptom-rating scales (HAMA/HAMD/BPRS).We summarized the overall proportion of patients with impaired mental health based on the data acquired from preliminary screening,and then calculated occurrence rates of each clinical syndrome of mental disorder according to symptom conclusions.The impact of comorbid mental illness was evaluated through the follow-up scheduled 1 year later,by comparing the survival rate,progression of disease,and quality of life (QoL) between subgroup patients with or without clinical syndrome of mental disorder.Results In preliminary screenings,26.1％ (595/2279) yielded positive results.Further symptom conclusions confirmed 15.8％ (359/2279) with clinical syndrome of mental disorder.Regarding specific type of syndrome,the occurrence rates of depression,anxiety,psychotic symptoms,and stress-related disorders were 13.3％,10.2％,2.8％,and 1.4％,respectively.Follow-up assessments were successfully performed in 1918 subjects (84.2％).Further analyses indicated that although insignificant influence was observed in terms of 1-year survival rate and disease progression,cancer patients with a clinical syndrome of mental disorder obtained significantly lower levels (P ＜0.05) in five domains of QoL (scored by QLQ-C30).Conclusion In China,at least 26％ of cancer patients experienced impaired mental health,of which 60％ already had a detectable clinical syndrome of mental disorder,which could significantly undermine their QoL.

Objective To understand the correlations between HIV-1 subtypes and changes in CD4+T cell count over time in patients with different subtypes of HIV-1 infection.Methods A total of 94 patients who were diagnosed with HIV-1 infection in Nanjing and received at least twice CD4+T cell counting test before antiretroviral therapy (ART) were recruited in this study.Descriptive analysis was used to present the rates of CD4+T cell decline for different HIV-1 subtypes.Logistic regression analysis and nonparametric test were conducted to investigate the factors responsible for CD4+T cell decline and to analyze the correlations between the rates of CD4+T cell decline and HIV-1 subtypes.Results The median monthly rate of CD4+T cell decline was-2.20 [interquartile range (IQR):-11.36-2.13] cell/μl.Of all patients,25.5% (24/94) had a significant decline (≥30%) in CD4+T cell count.Compared with the patients infected with CRF01_AE,those infected with CRF07_BC (OR=0.28,95%CI: 1.7-6.5) or other subtypes (OR=0.16,95%CI: 1.0-2.9) had a lower risk of significant decline in CD4+T cell count.In addition,results of the nonparametric test showed that the patients infected with CRF01_AE (M=-21.54,IQR:-30.97——11.92 cell/μl) had a faster CD4+T cell loss than those infected with CRF07_BC (M=-11.26,IQR:-14.06——5.63 cell/μl) (P=0.033).Conclusion HIV-1 subtype is associated with the rate of CD4+T cell decline.It is important to monitor the changes in CD4+T cell count in patients infected with CRF01_AE and to carry out timely ART.

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 study the immunoregulatory effects of thalidomide on the peripheral blood T-lymphocytes of rheumatoid arthritis patients.Methods MTr was used to detect the effects of different thalidomide concentrations on the proliferation of T-cells.Flow eytometry was used to analyze T-cells early apoptosis and the T-cells subsets in different concentration of thalidomide.The mRNA expression of IL-6,IL- 10 and TNF-α was measured by RT-PCR method.Results The level of thalidomide at 500 μg/ml inhibited the proliferation of T-ceils and the CD3+CD28+ expression of T-cell subsets,but promoted the early apoptosis and the CD8+CD152+ expression of T-cell subsets.Thalidomine at any concentration could inhibit the mRNA expression of IL-6,TNF-α.However,the level of thalidomide that could promote the mRNA expression of IL- 10 was 100 μg/ml and 500 μg/ml.Conclusion Thalidomide can inhibit the proliferation of T lymphocytes and the expression of CD3+CD28+ on T-cell subsets.It can promote the early apoptosis and the CD8+CD152+ expression of T-cell subsets.Thalidomide inhibits the mRNA expression of IL-6 and TNF-α but promote the mRNA expression of IL-10.Thalidomide has immuno-regulatory effects on rheumatoid arthritis T-cells.
