Objective To explore the risk factors of newborns with hypoglycemia and its prevention methods.Methods Clinical data of 1342 newborns were analyzed retrospectively,and the risk factors of newborns with hypoglycemia and its prevention methods were summarized.Results Of 1342 newborns,104 cases(7.75％)were confirmed with diagnoses of neonatal hypoglycemia.The duration of 56 cases(53.85％)was less than 1 day and 9 cases(8.65％)was more than 3 days,while 39 cases(37.5％)was 1 day to 3 days.The incidence of hypoglycemia of newborns(gestational age＜37 weeks)was higher than that of those newborns(gestational age ≥ 37 weeks)(P＜0.05).The incidence of hypoglycemia with the birth weight from 2500g to 4000g was lower than the newborns with the birth weight more than 4000g or less than 2500g(P＜0.05).The incidence of hypoglycemia of vaginal delivery newborns was lower than that of cesarean sectior newborns(P＜0.05).Conclusion The key point of treatment for newborns with hypoglycemia is prevention.For the neonates who are likely to suffer from hypoglycemia,blood sugar level needs to monitor frequently.Early diagnosis,detection and corrective measures could avoid damages to the central nervous system of neonates caused by hypoglycemia.

Objective To explore morphologic characterizatics of cellular processes from adult human nucleus pulposus cells. Methods The nucleus pulposus of adult human intervertebral disc were obtained from 8 patients(Thompson's grade Ⅰ-Ⅱ) and then the tissues specimens were carried out by frozen section and electron microscopic section as well as cell isolation and cultured,processes of nucleus pulposus cells were examined using light microscopy,laser scanning confocal microscopy and transmission electron microscopy. Results When examined at both the confocal and electron microscope level,all the cells possessed the processes and adjacent nucleus pulposus cells processes possessed a gap junction.The elongated and round cells were examined when NP cells became monolayer in vitro.The rate of elongated cells to round cells was 2.3 to 1.The elongated cells protruded along with the long axis of cell body without second processes.Dendritic processes of round cells protruded to all directions from the cell body with multiple-level processes.Conclusion Processes are one of the morphologic characteristics of intervertebral disc cells.The research on processes functions could be helpful to understand pathomechanism of intervertebral disc degradation.

Objective To investigate the efficacy of PEG-INF alpha-2a(PEG-INF-2a)on patients with chronic hepatitis C.Methods 60 patients with hepatitis C were included in this study.30 patients were treated with PEGINF-2a(180μg or 135μg/week)and RBV 900mg/d,30 patients were treated with IFNα-2a(5 MIU/qod)and RBV 900 mg/d.The time of treatment was 48 weeks,and all the patients were followed up for 24 weeks after treatment.There was no significant difference between the two groups in pretreatment HCV-RNA,HCV genotype and other clinical data.The main parameters to evaluate the efficacy were virological and biochemical responses.The side effects were intensively observed.Results Sustained vimlogical response(SVR)rate in PEG-IFNα-2a group was significantly higher than that in IFNα-2a group(56.5%and 19.5%respectively,P＜0.01).As the patients were divided according to HCV genotype 1 and high virus load.the SVR rate of PEG-IFNα-2a group Was higher than IFNα-2a group(P＜0.01).However,there was no significant difference between two groups in the patients with non-genotype 1 and low viral load(P=0.664,0.116).Similar side-effects were observed in PEG IFNα-2a group and IFNα-2a group,but the rate of weisht decline and the degree of leukocyte decrease were more significant in PEG IFNα-2a group than in IFNα-2a group(P＜0.01).Conclusion The efficacy of PEG IFNα-2a in the treatment of chromic hepatitis C is superior to that of conventional IFNα-2a,PEG-IFNα-2a had good tolerance and safety profiles.

Objective To investigate wheter epigallocatechin gallate (EGCG) could prevent the information of abrant crypt loci (ACF) induced by isoquinoline (IQ)and its possible mechanisms. Methods Sixty male BALB/cA nude immunological deficit mice were divided into five groups. Except control group, the other four groups were received IQ to induce ACF. The rats in low, medium and high dose groups were received 5, 10 and 20 mg/kg of EGCG,respectively. The mice were sacrificed six weeks later. Hematoxylin-eosin (HE) staining and 0.2% methylene blue staining were used to observe the routine histology and ACF, respectively. Immunohistochemistry (IHC) was used to detect Nrf2 protein level and RT-PCR was used to detect Nrf2 and UGT1A10 mRNA levels in colon tissue. Results The body weights of model group decreased significantly compared to high-dose group (21.70±0.13 vs. 24.37±0.07, P<0.01). Compared to model group, the degree of atypical hyperplasia and even canceration of colon mucus and the number of total ACF and total AC in high-dose group were decreased significantly (18.00±7.51 vs. 64.20±45.18, P<0.05;63.90±18.58 vs. 168. 80±35.34, P<0.01). The protein level of Nrf2 increased (0.3114±0.0037 vs. 0.1660±0.0021, P<0.01). The mRNA levels of Nrf2 and UGT1A10 in high-dose group was increased (both P value<0.01). Conclusions EGCG has protective effect on IQ induced preneoplastic lesions through reducing the number of ACF. This effect may be caused partly through the signal pathway Nrf2-UGT1A10.

Objective To analyze the incidence rate of congenital malformations in Xintai City from January 2010 to December 2013,and to investigate the risk factors for neonatal malformations. Methods A total of 21 463 ca-ses of perinatal infants pregnant for 28 weeks later to postpartum 7 d in Xintai city from January 2010 to December 2013 were retrospectively analyzed. The congenital malformations detection data were analyzed. The risk factors were analyzed by univariate and Logistic analysis methods. Results There were 281 cases with congenital malformations were identi-fied out,and the congenital malformation rate was 1. 31%(281 / 21 463 cases). The incidence rates of multi - finger (toe)[0. 24%(52 / 21 463 cases)],cleft lip[0. 23%(49 / 21 463 cases)],and congenital heart disease[0. 22%(47 /21 463 cases)]were the main congenital malformations. Total malformation rates in the year of 2010,2011,2012,and 2013 were similar(1. 26% ,1. 25% ,1. 33% ,1. 26% ,Z = - 1. 826,P = 0. 068). Univariate and Logistic regression analysis results showed that birth weight,parity,births number,gestational age,educational level,residence,income,ill-ness history,exposure to pesticides,hepatitis,influenza,severe vomiting of pregnancy,threatened abortion,threatened premature,contraceptives,smoking history,drinking history,and father's chronic disease were the risk factors for neo-natal congenital malformations( χ2 = 10. 212,4. 299,5. 860,5. 278,10. 422,9. 327,15. 680,127. 395,245. 735, 74. 141,718. 876,96. 414,77. 770,11. 300,9. 126,74. 927,68. 283,5. 450,P = 0. 001,0. 038,0. 015,0. 022, 0. 001,0. 002,0. 000,0. 000,0. 000,0. 000,0. 000,0. 000,0. 001,0. 001,0. 003,0. 000,0. 000,0. 020 ). Conclusions Neonatal congenital malformation is mainly determined by genetic and environmental factors. For childbearing age and pregnant women,targeted health education should be strengthened to reduce the incidence rate of congenital malformations.

Malnutrition is one of the most important factors for the prognosis of patients with gastric cancer,but the mechanism of malnutrition is unclear at present. These patients are at risk of nutritional deple-tion from anorexia,dysphagia,and may be associated with the presence of two or more of the following cyto-kines with metabolic activity such as TNF-α,IL-1,IL-6,interferon,leptin,nuclear factor-κB and so on, which are secreted by the host-tumor interaction. The cytokines constitute a sophisticated regulatory network. Therefore,the study of the relationship between malnutrition and related factors in patients with gastric cancer may improve the nutritional status and prognosis of these patients.
