Objective To explore perinatal risk factors associated with the neurobehavioral development of small for gestational age (SGA) full-term neonates.Methods This prospective cross-sectional study included 111 full-term newborn infants from Apr 2008 to Apr 2010 born in Yan-tai Yuhuangding Hospital.Detailed clinical data in perinatal period of all subjects were recorded.Infants aged 3 ～ 7 days were assessed with neonatal behavioral neurological assessment (NBNA) for neurobehavioral development.Logistic regression analysis was used to explore risk factors associated with the score of NBNA.Results Significant differences (P ＜ 0.05) were found between full-term SGA (10.72 ± 1.41,7.13 ± 0.96,7.32 ± 0.74,37.16 ±1.32) and normal neonates (11.27 ± 1.04,7.89 ± 0.72,7.62 ± 0.64,39.12 ± 0.76) in terms of capacity,active and passive muscle tension and NBNA score.Full-term SGA neonates had lower score than control.Univariate logistic regression showed that delivery,placenta abnormalities,umbilical cord abnormalities,infection in perinatal period,gestational hypertension,twin pregnancy,hyperbilirubinemia affected neurobehavioral development of full-term SGA infants.Multivariate logistic regression showed that mothers' infection in perinatal period (OR =2.175,95 ％ CI 1.981 ～ 2.408,P ＜ 0.05),twin pregnancy (OR =1.936,95％ CI 1.517 ～2.368,P ＜ 0.05) and hyperbilirubinemia (OR =1.518,95％ CI 1.072-2.149,P ＜ 0.05) were risk factors for neurobehavioral delay of full-term SGA infants.Conclusion Full-term SGA neonates showed poorer quality in neurobehavior.Risk factors associated with neurobehavior of full-term SGA infants included mothers' infection in perinatal period,twin pregnancy and hyperbilirubinemia.

To explore the changes of mitochondrial membrane potential in rat cadiomyocyte apoptosis by fluorescent JC 1, H 2 O 2 was used to induce cadiomyocyte apoptosis, and JC 1 in combination with flow cyometry was used to detect the changes of mitochondrial membrane potential in the early stage of cadiomyocyte apoptosis. The results showed that living cardiomyocytes had a high mitochondrial membrane potential, JC 1 aggregates were formed in the inner membrane of mitochondria and emitted orange red fluorescence. H 2 O 2 caused the decrease of mitochondrial membrane potential, JC 1 aggregates were dissociated to monomer,which emitted green fluorenscence. So the red fluorescence decreased. It is suggested that JC 1 in combination with flow cyometry is an ideal method to detect the changes of mitochondrial membrane potential.

5 ml groups were 95.5% and 81.1% respectively. This difference was statistically significant (P5 ml groups were 4.5 % and 32.1%, respectively (P50 Gy was increased statistically, but the occurrence of complications was also increased. Conclusions Stereotactic radiosurgery improves the outcome of the elderly patients with brain metastases. Radiation dosage and tumor volume are significantly related with the therapeutic efficacy and the occurrence of complications.

Objective The derivative of Gefitinib was used to treat glioma cells in vitro to explore a more effective new drug for the clinical treatment of astrocytoma. Methods (1) Fifteen kinds of gefitinib derivatives, gefitinib and temozolomide were used to treat glioma cells, and the effect of 0, 10, 15, 20, 25 and 30 μmol/L of each kind of drug on cell proliferation was detected by by MTT assay , respectively. (2) To calculate the concentration of IC50 , then select lower IC50 of derivativs combinate gefitinib and temozolomide with 10, 20 and 30 μmol/L to treat cells, then the apoptosis of cells were detected by flow cytometry. Expression of p-EGFR was detected by western–blot assay. Results (1) NO.LPY-5,9,11, but not other derivatives of Gefitinib could effectively inhibit the growth of cells. (2) IC50 of NO.LPY-9 was less than that of the 5th drug, and both of them were lower than those of gefitinib and temozolomide; NO. LPY-11 was excluded. (3) The cell apoptosis of No. LPY-9 was higher than that of gefitinib and temozolomide , respectively. However, No.LPY-9-induced cell apoptosis was significantly higher than that of No. LPY-5-induced cell. (4) Levels of p-EGFR expression in No.LPY-9 and gefitini-induced cells were significantly lower than that in the negative control group. Conclusion No.LPY-9 has asignificant inhibitory effect on glioma cells in vitro , resulting from the inhibition of the ERFR-mediated signaling pathways and induction of cell apoptosis.

Objective To investigate the clinical treatment of infective endocarditis with vegetations in pregnant women and the outcomes of the gestation. Methods Nine cases of pregnant women diagnosed as infective endocarditis with vegetations in Beijing Anzhen Hospital, Capital Medical University from January 2001 to October 2015 were enrolled in retrospective analysis. Consultations were held by doctors from department of obstetrics, anesthesiology, cardiology, cardial surgery and extracorporeal circulation to decide the individualized treatment plan for the 9 cases of pregnant women after admissions. Clinical treatments including general treatment, anti-infection treatment, cardiac surgery, and termination of pregnancy surgery were completed through collaboration among related departments. The clinical characters, therapeutic regimens, maternal and neonatal outcomes of the 9 cases were analyzed. Results (1)Clinical characters: the ages of the 9 cases of pregnant women were from 25 to 36 years old. The onset gestational ages were from 19 to 36 weeks. Clinical symptoms: fever, cough, sputum and progressive anemia were the main symptoms. Patients had cyanosis of lips, could not lie on the back or even be orthopnea, when heart failure happened. Heart murmur was audible and splenomegaly was touched in physical examination. Blood cultures were positive. Basic heart disease types: 7 cases of congenital heart diseases included 2 cases of aortic insufficiency, 1 case of mitral insufficiency, 1 case of patent ductus arteriosus, 1 case of right ventricular outflow tract stenosis and 2 cases of ventricular septal defect.Two cases of rheumatic heart diseases included 1 case of mitral stenosis, 1 case of mitral stenosis after artificial disc changed and jammed. According to endocardial vegetations attached position there were 3 cases of mitral valve vegetations, 2 cases of pulmonary valve vegetations, 3 cases of aortic vegetations and 1 case of right ventricular outflow tract neoplasm. Preoperative heart function classification:1 case of levelⅡ, 3 cases of levelⅢ, 5 cases of levelⅣ.(2)Treatments:general treatment included oxygen uptake, rest in bed, cardiac strengthen and diuretic therapy, etc. Combined and adequate antibiotics were applied in anti-infection treatment according to drug sensitive test. Nine cases of pregnant women were all performed surgical treatment of heart diseases and removal of the endocardial vegetations. Caesarean sections were performed for 2 cases in second trimester and for 7 cases in last trimester. Cardiac surgery and caesarean section were operated in 6 cases at the same time among 22-34 weeks of pregnancy. Cardiac surgery were respectively operated in 2 cases 11 days and 32 days after the caesarean section at 33, 37 weeks of pregnancy. While Cardiac surgery was operated (at 26 weeks of pregnancy) before the caesarean section (at 37 weeks of pregnancy) in another 1 case. (3) Maternal and neonatal outcomes:7 cases of pregnant women were rescued successfully, while 2 cases of pregnant women were death. Postoperative heart function classification: 1 case of level Ⅰ, 2 cases of levelⅡ, 4 cases of levelⅢand 2 cases of levelⅥ. Neonatal survivals were 6 cases including 2case of full-term infants, 4 cases of preterm infants. Stillbirth or neonatal death were 3 cases, which included 2 cases performed caesarean section in second trimester and 1 case of very low weight infant who was given up treatment by family because of severe asphyxia. Followed up periods were from 1 to 7 years with an average time of (2.0 ± 1.6) years. Infants and young children grew and developed well during the period of follow up. Conclusions The risk is extremely high of pregnancy with infective endocarditis with vegetations. But there is still a way to save the maternal and neonatal life by using a multidisciplinary collaboration formulation and implementation of individualized treatment plan and selecting the appropriate time for heart surgery and the termination of pregnancy.

BACKGROUND:Currently, there are few researches on the effect of punicalagin on the formation and differentiation of osteoclasts, and fewer researches on the mechanism of bone resorption diseases induced by wear particles. OBJECTIVE: To establish a model of titanium particles induced mouse monocyte/macrophage cel line (RAW264.7) differentiating into osteoclasts and to observe the effect of different concentrations of punicalagins on osteoclast proliferation and differentiation. METHODS: Mouse monocyte/macrophage cel lines (RAW264.7) were divided into five groups, cultured in the culture medium of common (blank group), 0.1 g/L titanium particle suspension, 0.1 g/L titanium particle suspension with 25 μmol/L punicalagins, 0.1 g/L titanium particle suspension with 50 μmol/L punicalagins, 0.1 g/L titanium particle suspension with 100 μmol/L punicalagins, respectively. The cel proliferative activity was detected by cel counting kit-8 assay at 1, 3 and 5 days. At 5 days after culture, number of osteoclasts was measured by tartrate-resistant acid phosphatase staining, the phosphorylation of IκBα and NF-κB p65 was detected by western blot assay, the mRNA expressions of nuclear factor of activated Tc1, tartrate-resistant acid phosphatase and matrix metaloproteinase-9 were measured by reverse transcription-PCR. RESULTS AND CONCLUSION:Compared with control group, titanium particles and different concentrations of punicalagin had no effect on the proliferation of RAW264.7 cels (P > 0.05). The number of tartrate-resistant acid phosphatase staining -positive cels, the phosphorylation of IκBα and NF-κB p65 as wel as the mRNA expressions of nuclear factor of activated Tc1, tartrate-resistant acid phosphatase and matrix metaloproteinase-9 were significantly increased compared with those of control group (P < 0.05,P < 0.01). And punicalagins in a concentration-dependent manner decreased the expression of the above indicators. These results indicate that punicalagin can inhibit osteoclast formation and differentiation.

Objective To explore gene polymorphism of the C/T genotype of rs1143627 in the promoter of IL-1β gene in male population living in the coastal area of Shandong, and thus to investigate the relationship between the gene polymorphism of IL-1β and gout. Methods A total of 208 gout patients and 210 healthy controls were enrolled. The possible association between the polymorphism of IL-1 β -3 1C/T and gout in Chinese were investigated and genotype frequencies and allelic frequencies was calculated by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. Hardy-Weinberg was used to verify the representativeness of the sample. Comparisons between the groups were performed with χ2 test and t-test. Results The frequencies of CC, CT, and TT genotypes were 32.7%, 43.3% and 24.0%,respectively among gout patients, while they were 31.9%,46.2% and 21.9%, respectively among the controls.There was no statistically difference in IL-1β -31C/T genotype frequencies between gout patients and controls (χ2=0.427, P>0.05). The allele frequencies of C and T in gout cases were different from those in the controls (54.3%, 55.0%; 45.7%, 45.0%; χ2=0.038, P>0.05). Moreover, no association between IL- I β-31 C/T genotypes and risk factors for gout were observed in gout cases by χ2 test. Conclusion Results of the present study suggest that the C/T genotype of rs1143627 in the promoter of IL-1β gene is not associated with gout in male population living in the coastal area of Shandong.

Objective To investigate the possible influence of immunosuppressive therapy,including sirolimus (SRL) and calcineurin inhibitors (CNI, tacrolimus), on level of Treg in the liver allo-graft recipients, Methods Forty-seven liver transplant recipients with stable liver function were assessed for at least 2 years, and divided into two groups: one composed of 15 patients receiving SRL,and another, of those receiving CNI (32 patients with tacrolimus). Thirty-eight age-matched healthy subjects (HS) were used as normal controls. We examined the expression of CD4, CD25, and Foxp3 in peripheral blood monouclear cells. Treg of every group was analyzed using Cell Quest software.Results SRL significantly increased the prevalence of CD4+ CD25high T cells, compared with HS and CNI group. The prevalence of CD4+ CD25high T cells of CNIs group was significantly lower than that of HS. The percentage of CD4+ CD25high T cells in the total CD4+ T cells was 1.88 % (1.56 %-2. 60 %), 1. 15 % (0. 57 %-l. 48 %) and 0. 84 % (0. 46 %-1. 45 %) in SRL, NS and CNI group,respectively (P<0. 01 or P<0. 05). Foxp3 was expressed in more than 95 % of CD4 + CD25high T cells and less than 20 % of CD4+ CD25low T cells, whereas not expressed in CD4+ CD25- T cells.Conclusion Different immunosuppressive therapy (SRL or CNI) might have different roles in tolerance induction in liver transplant recipients. Namely, SRL promoted the induction of allo-antigen tolerance, but CNI hampered the progression.
