Objective: To compare the differences between urban and rural middle school students on life satisfaction. Methods: 1152 urban and rural middle school students were measured by Multidimensional Students'Life Satisfaction Scale ( MSLSS - CV) . Results: ( 1 ) The urban students had higher scores than their rural counterparts on all the satisfaction dimensions ( mean value differences = 0. 2 - 0. 4. For example, the family satisfaction of urban and rural students were 4. 6?1. 0, 4. 2?1.0 respectively, mean value difference =0. 4; the serf satisfaction of urban and rural students were 4. 6?0. 7 , 4. 4?0. 7 respectively, mean value difference = 0. 2 ) . ( 2 ) The mean values rank (from high to low) of the five dimensions on the satisfaction was family, self, friend, school and living environment in urban students. The mean values rank (from high to low) of the five dimensions on the satisfaction was self, family, friend, school and living environment in rural students. (3 ) The difference between city and countryside had higher explained percentage than popularity on all the satisfaction dimensions. The percents were as follows: 5% , 10% , 4% , 6% , 17% , 11%. Conclusion: There were significant differences on life satisfaction between urban and rural middle school students.

[Objective]To observe the effects of chronic renal failure (CRF)on hearing and investigate its mechanism.[Methods] Twenty-nine male wistar rats were randomly divided into four groups:Ⅰthe normal rats as control for 12 days (n=6); Ⅱrats given adenine(ig) for 12 days (n=8); Ⅲthe normal rats as control for 24 days (n=6);Ⅳ rats given adenine(ig) for 24 days(n=9). The rat model of CRF was produced by being perfused of adenine [300mg/kg]for 12d and 24d. Brain-stem auditory evoked potential(BAEP) was utilized to evaluate the auditory function and renal tissue morphology was observed; Serum sampling was used to determine the content of Cr, BuN. The expression of NOSⅡin the cochlear was measured by immunohistochemical technique.[Results] After adenine given for 12d or 24d, the Cr and BuN were in significant higher level than that in control group. The BAEP thresholds were gradually higher than that in control group, the BAEP delitescence prolonged. Light microscopic observation of renal tissue showed that the degree of fibrosis was gradually higher. Data of immune histochemistry about the cochlear tissue showed that the expressions of NOSⅡ were feebly positive in the cochlear vassal texture, inner-outer hairy cell and helical-ganglion cell, and following functional damage of the kidney, their expressions reinforced gradually, amongst which strongest expression was vassal texture, the next helical-ganglion cell, the last inner-outer hairy cell.[Conclusion]CRF can result in deafness. It is likely concerned with toxic effects of the metabolizable substance, the metabolizable dysfunction of the electrolyte, shortage of trace elements, etc. One of the important mechanisms of the effects of CRF on hearing is the toxic damage of NO to cochlea.

Translational medicine is an emerging idea in current medical research area. Typically, for the purpose of bridging the gap between basic and clinical research, it not only emphasizes the urgency and necessity to break the traditional working formats, including single subject centered research team and limited cooperation among different scientific groups, but also highlights a more close and frequent interaction between basic scientist and clinician. In order to reach this goal, the theory and method of systems biology should be employed. This paper mainly focused on a central issue that how to carry out an investigation on early clinical diagnosis of xenobiotic-induced intrauterine growth retardation (IUGR) by using research concept of translational medicine and method of systems biology. Briefly, a hypothesis of common mechanism of IUGR was first proposed and subsequent validation was performed via integrating--omics (e.g. genomics, proteomics, cytomics, metabonomics/metabolomics) and molecular biology techniques. Metabonomics was further utilized to explore IUGR biomarker and establish preliminary forecasting model by bioinformatics and computational biology, which is available for early diagnosis of IUGR and make a complement to current evaluation criteria.

Objective To investigate the significance of human cyomeg Movirus(HCMV)pp65 IgG antibody avidity index(AI)for the clinical diagnosis of HCMV primary infection through the experimental model of HCMV primaly infection in BALB/c mice.Methods 6～8 weeks,female,specific-pathogen-free BALB/c mice were divided into 5 groups.6 mice in each group. And he mice were injected with 2×106 PFU/m1,2×105 PFU/mi,2×104 PFU/ml,2×103 PFU/ml and 2×102 PFU/ml of HCMV intraperitoneally respectively. Another 6 mice were injected intraperitoneally with the maximum dose of HCMV kept at 56℃ for 30 min as inactivated virus group.And HF negative control group was established at same time. All the mice ere sacrificed to obtain brain and lung tissues for the following experiments after 1 montll.(1)Tissue samples obtained from mice were inoculated in human embryo fibroblasts(HF)monolayers after routine treatment for virus isolation.HCMV specific eytopathie effect(CPE) was observed bv inverted phase-contrast microscopy.HCMV UL83 DNA in the ultures as tested by PCR and pp65 antigen was detected by indirect immunofluorescence.(2)Extracted mRNA from tissue samples and HCMV pp67 mRNA were analyzed by reverse transcriptase PCR(RT-PcR).(3)Immunoglobulin M(IgM)antibody and immunoglobulin G(1gG)antibody avidity Was investigated for their usefulness in distinguishing primary genital HCMV infections rom nonprimary infections with ELISA kit using truncated pp65 protein.ResultsHCMV can be isolated in the tissues from the mice injected with 2×106 PFU/ml and 2×105 PFU/m1.RT- PCR and ELISA showed positive results in the same groups.The infective rates were 100%.The analysis of the low doses groups,inactivated group and HF negative ontrol group all showed negative results.Conclusions BALB/c mice can be infected with HCMV and appeared as primary infection after1 month.Determination of HCMV pp65 IgM and HCMV p065 IgG-AI by ELISA incorporated with virus isolation and RT-PCR are helpful for distinguishing primary infections from nonpfimary infections.The detection of HCMV p65 IgM and HCMV pp65 IgG-AI by ELISA utilizing recombinant protein pp5 as antigens can be used for preliminary screening.

Objective To study the clinical application value of the low forceps in vaginal delivery. Methods To retrospectively analyze the clinical data of 280 cases of the low forceps in vaginal delivery,and randomly selected 140 cases pregnant women who cesarean section, as the control group. To compare the influence of maternal and neonatal morbidity in the two groups. Results There were no statistically significant differences between the two groups for the incidence of the postdelivery hemorrage,birth trauma infectious, asphyxia neonatorum associated with delivery from low forceps when compared with cesarean section. The incidenc of the postdelivery sick rate was significantly lower in the low forceps group( 3.2% ) than that in the control group ( 10.0% ) ( x2 = 8.30, P ＜ 0.05 ). Conclusion Low forceps may be a valuable instrument and safety or efficacy in vaginal delivery and that it should be more widely used in appropriate clinical situations.

Objective To explore the influence of cerebral hemorrhage stress on endothelial progenitor cells(EPCs) proliferation and senescence. Methods Mononuclear cells from peripheral blood of patients with cerebral hemorrhage (CH group) and patients with the same underling diseases (control group) as the front were isolated and induced to EPCs. Proliferation, numbers of colonies and cells, senescence of EPCs were checked and compared between the two groups. Results Compared with control group, proliferation (0.270 ± 0. 074 vs 0. 185 ±0.050, t=3.802) ,numbers of colonies( (5. l0 ±0.79) cell/HPF vs ( 1.90 ±0.41 ) cell/HPF, t= 14.407) and cells( (75.15 ± 10.48) cell/HPF vs(57.10 ± 9.28 ) cell/HPF, t = 5. 157 ) of EPCs in CH group on the stress of cerebral hemorrhage were increased significantly (P ＜ 0.01 ), but senescence of EPCs ( (45.54 ± 5.74 ) cells/100 cells vs ( 46.86 ± 5.06 ) cells/100 cells, t = 0. 686 ) in two groups were not different (P ＞ 0.05 ). Conclusion Cerebral hemorrhage stress can increase proliferation of EPCs,but can not change the senescence destiny of EPCs.
