Objective To study clinical significance of S-100B protein in umbilical cord blood of asphyxial neonates with hypoxic-ischemic encephalopathy(HIE).Methods Forty-three cases of healthy infants were regarded as control group(group 1).Sixty cases of asphyxial neonates were divided into two groups(44 cases without HIE as group 2;another 16 cases with HIE as group 3).S-100B protein levels in umbilical cord blood of three groups were measured with enzyme-linked immunosorbent assay retrospectively. Results Levels of S-100B protein in group 1,group 2 and group 3 were(1.055?0.356) ?g/L,(1.572?0.533) ?g/L and(2.394?(0.943) ?g/L,) respectively.S-100B protein levels in umbilical cord blood of group 2 and group 3 were significantly higher than that of group 1(t=2.306,7.991 P

Objective To learn the current obstetric beds allocation,obstetric service delivery and access in midwifery institutions at various levels in the localities and nationwide as well as the trends,and assess the equity of obstetric beds allocation,for the purpose of recommending on a reasonable adjustment of obstetric beds allocation in these institutions.Methods Random sampling made in 44 cities in China for questionnaire survey on obstetric beds allocation,service delivery and utilization in 2008～2010 at all midwifery institutions in these cities.Interview of health administrators and medical workers at obstetric of midwifery institutions in 6 counties.Results Every thousand square kilometers in China average 5.9 midwifery institutions,and every thousand people average 0.24 obstetric beds.During 2008 ～ 2010,the number of beds and midwifery service delivery kept a growing trend while in townships obstetric service deliveries maintain a falling trend.The fairness index of maternity beds layout nationwide is 0.021283.Obstetric beds supply and demand ratio in different regions ranges among 0.97～ 1.41.The number of deliveries made in county level hospitals is 54.1％,but the beds in such hospitals account for but 48.1％.Conclusion The equity of obstetric beds allocation is good in terms of population layout.The quantity of obstetric beds meets the current needs nationwide,while the allocation of obstetric beds is less than reasonable among obstetric institutions of various levels in the country.The authors recommend a better control and adjustment of midwifery institutions layout,especially more such hospitals at the township level to meet the need of women delivery in hospital in remote areas.

Objective:To investigate the significance of 25 ( OH )-vitamin D in its diagnostic value of primary biliary cirrhosis. Methods:44 cases with PBC,41 cases with Hepatitis B cirrhosis and 110 normal people as control group were all analyzed bi-ochemical results and significance of serum 25 ( OH )-vitamin D. We Used receiver operator characteristic curve ( ROC ) to analyze serum 25(OH)-vitamin D in its diagnostic value of primary biliary cirrhosis. Results:Biochemical results of TBIL,DBIL,IBIL,GLB, AST,ALT,ALP,γ-GT were higher in PBC than that in normal people and Hepatitis B cirrhosis. While the serum 25(OH)-vitamin D of PBC was much more lower than that in normal and people and Hepatitis B cirrhosis. The difference between them were statistical difference(P<0. 05). The area under the ROC curve of PBC was 0. 926,it showed serum 25(OH)-vitamin D diagnosis for PBC had quite value. When the cut-off level of serum 25(OH)-vitamin D was 17. 275 ng/ml,the sensitivity for the diagnosis was 92. 8%,the re-spectively was 84. 1%. Conclusion:Serum 25(OH)-vitamin D diagnosis for PBC has quite value,the cut-off level of serum 25(OH)-vitamin D is 17. 275 ng/ml.

ObjectiveTo investigate the effect of clinical pathway teaching methord in nursing practice teaching. Methods80 junior college nursing students were randomly divided into control and experimental groups. Traditional clinical teaching method was given to control group, while the clinical pathway teaching method was given to observation group. Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.

Objective To study the changes and significance of Bid gene expression in hypoxic-ischemic brain damage (HIBD) in neonatal rats.Methods The animal models of HIBD were made. Total RNA from ipsilateral cerebral hemisph ere was extracted.RT-PCR was used to evaluate the levels of Bid gene expression at different time points after hypoxic-ischemic. Results The levels of Bid mRNA were higher in HIBD rats than those in normal rats.The ex pression of Bid mRNA in ipsilateral hemiphere following cerebral hypoxic-ischem ic began to increase at 6 h, increased to the highest level at 24 h, and then gr adually returned.Conclusion The upregulation of Bid mRNA can play a role in the induction of apoptosis fol lowing cerebral hypoxic-ischemic.

AIM: To screen TIGR/myocilin gene (MYOC) mutation in high myopic Chinese children with family history.METHODS: Gene sequencing was performed in exon 3 of the TIGR gene in high myopic Chinese Children. The coding sequence of TIGR exon 3 was screened by capillary electrophoresis sequencing. The sequence alterations were analyzed by bioinformatics.RESULTS: TIGR gene mutation was not found in high myopic patients and normal controls group.CONCLUSION: No identified gene mutation is found in TIGR gene in high myopic Chinese children.

Objective To explore the changes of gut microbiota in response to abdominal and pelvic radiotherapy and its potential relationship with intestinal infection.Methods Irradiation was delivered to the abdominal region of BALB/c mice,following the regular human pelvic-radiotherapy protocol,2.0 Gy/d,continuous 5 d/week.Samples of ileum tissue and the intestinal content were collected at different time points of irradiation procedure,including after 3 and 5 weeks,and at 1 week after 6 weeks of irradiation.Quantitative RT-PCR was used to measure the mRNA level of antimicrobial peptides and pro-inflammtory factors.Bacterial translocation was determined by PCR.The gut microbiota was characterized by the denaturing gradient electrophoresis assay.Results The expressions of cryptdin-1 and cryptdin-4 were decreased after 3 weeks of irradiation and at 1 week after 6 weeks of irradiation(t =-7.43,-3.54,-4.72,-4.27,P ＜ 0.05),while they were significantly increased at the 5 weeks of radiation (t =6.15,5.75,P ＜ 0.05).The diversity index and richness of gut microbiota after 3 or 5 weeks irradiation were significantly decreased (t =-3.49,-4.19,-3.44,-4.97,P ＜ 0.05).The gut microbiota dysbiosis of the irradiated mice was characterized with the decrease of probiotics of Lactobacillus and the increasing of opportunistic pathogen of Escherichia coli,Shigella flexneri,et al.Bacterial translocation episodes were more frequently in the irradiated mice than that of control animal.The mRNA levels of IL-1β、IL-6 and TNF-α were significantly increased after 3 or 5 weeks of irradiation (t =4.85,6.16,7.71,4.60,4.86,5.97,P ＜ 0.05).Compared with the control,the expression levels of IL-1β and TNF-α at the 1 week after 6 weeks of irradiation ending was also obviously enhanced (t =3.67,5.88,P ＜0.05).Conclusions Pelvic radiotherapy can induce abnormality of enteric antimicrobial peptides and may result in gut microbiota dysbiosis.The disturbed gut microbial flora may further trigger an incurrence of bacterial translocation and enteritis.Therefore,the gut microbiota may be a potential interfering target to alleviate radiotherapy adverse effect.

Objective To explore the role of serum S-100B concentration of umbilical cord blood and blood on the 24 h after admission in the early diagnosis and development of newborn hypoxic-ischemic encephalopathy(HIE).Methods Forty-six HIE newborns(31 cases with mild HIE and 15 cases with moderate and severe HIE)were selected as HIE group,and 43 normal full-term newborns were selected as control group.The umbilical cord blood sample and blood sample were aquired on the 24 h after admission.The serum S-100B concentration was detected by enzyme-linked immunosorbent assay(ELISA)analysis.Results 1.There was no significant difference of serum S-100B concentration between the male sub-group and female sub-group of normal group and their birth weight had no significant relative to the serum S-100B concentration.2.The serum S-100B concentration of umbilical cord blood of control group and HIE group were(1.03?0.32)and(2.53?1.1)?g/L,respectively,there was significant difference between two groups(t'=8.848 P
