Objective To investigate different factors related to fetal growth restriction (FGR) and to find out the possible causes of FGR with unclear etiologies. Methods Sixty-three women who were suspected of FGR during pregnancy between March 2002 and March 2003 were included in this study. Their age, body mass index (BMI) before pregnancy, and gestational weeks were recorded at the time when they were first diagnosed . Haemoglobin levels, haematocrit (HCT) ,TORCH, anticardiolipin antibody (ACA) , 50 gram glucose challenge test (50g GCT) , 75 gram oral glucose tolerance test (75g OGTT) , leptin levels, systolic/diastolic (S/D) ratio by color doppler monitor and chlamydia trachomatis (CT) were detected and urine culture was done in these groups during the same period. The gestational week, birth weight, body length and the gender were recorded at the delivery period. The FGR group was then divided into two subgroups according to the birth weights: study A group whose birth weights were lower than 10th% of the birth weights at the given gestational weeks (29 cases) and study B group whose birth weights were beyond 10th% (34 cases). The chromosome, leptin, C-peptide, insulin and TORCH of umbilical blood were measured at delivery. The other 25 normal pregnant women were included as control and the same tests were performed accordingly. Results The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test of study A were( 3. 8 ?0, 6) mmol/L and (4. 5 ?1. 1) mmol/L. The fetal lepin, C-peptide, and insulin were (7.3 ? 5. 2) ng/ml, (0. 5 ? 0. 3) nmol/L and (2. 3 ? 1. 3 ) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of asymptomatic bacteriuria were 3.06, 20.7%, 24.1%, 44.8% and 62.1% respectively. The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test of study B were (4. 4 ? 0. 7) mmol/L and (4. 6 ? 1. 1 ) mmol/L. The fetal lepin, C-peptide, and insulin were ( 13. 2 ? 11. 3 ) ng/ml, (0. 7 ? 0. 4) nmol/L and (4.3 ? 3.3) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of asymptomatic bacteriuria were 2. 63, 2. 9% , 0% , 5.9% and 44. 1% respectively. The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test in control were (4. 3 ? 0. 7) mmol/L and (5. 3 ? 1.2) mmol/L. The fetal lepin, C-peptide, and insulin were( 20. 5 ? 12. 0) ng/ml, (1. 0 ? 0. 4) nmol/L and ( 6. 3 ? 4. 0) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of the asymptomatic bacteriuria were 2. 80, 0, 0, 0 and 24. 0% respectively. All these items were significantly higher in study A than those in the control (P

Objective To study the effects of combined telmisartan and ramiprll on heart function and renin - angiotensin - aldoste-tone system and ventricle remodeling and brain natriuretie peptide in patients with chronic heart failure (CHF). Methods 100 patientswith chronic heart failure were randomly divided into three groups: telmisartan group (A group, treated with telmisartan 80mg once daily, n =33), ramipril group (B group treated with ramipril 5mg once daily, n =33) and telmisartan plus ramipril group (treated with telmis-artan 40mg plus ramipril 2.5mg once daily, n = 34). Left ventricular end - diastolic dimensions (LVEDD) and left ventricular ejection fraction (LVEF) were assessed, and plasma renin activity (Ren) , angiotensinIl (Angll), aldosterone (Aid) and brain natriuretic pep-tide (BNP) were measured before and after therphy. Results After 6 months of treatment, LVEDD and LVEF were improved in all groups(P < 0.01). All changs were significant in C group than those in A group or B group(P < 0.01). The concentration of Ren were in-creased in all groups(P <0.01). The concentration of Angll was increased in A group and decreased in B group(P <0.01)while there was no difference at pre or post treatment in C group (P > 0.01). The concentration of Ald and BNP was decreased in all groups (P < 0.01). Ald and BNP were decreased more significantly in C group than those in A group or B group. Conclusion Combination of low dose of telmisartan and ramipril therapy has more benificial clinical features than telmisartan or ramipril alone in patients with CHF.

Objective To investigate the changes of the anion gap(AG)in the premature suffered from hyperbilirubinemia,to provide the basis for treatment.Methods The serum electrolyte,the renal function and the liver function in 94 premature babies suffered from hyperbilirubinemia were tested,and then calculated the value of AG,while the arterial blood gas analyses were done in 36 cases.Results 44 cases had high AG(46.81％),44 cases had normal AG(46.81％)and 6 cases had low AG(6.38％).The increase of AG was directly proportional to the concentration of Na+in blood,while was inversely proportion to the concentration of HCO3-.There was no close relationship between the AG and BUN,Scr in the serum.Conclusion The incidence rate of metabolic acidosis poisoning was high in premature suffered from hyperbilirubinemia with high AG,so the routine test of blood electrolyte,renal function and arterial blood gas should be done.Calculate the value of AG to guide the treatment,and to avoid correcting the acid by the alkali blindly.

Objective: To investigate the effect of vascular endothelial growth factor-C (VEGF-C) on invasive capability and proliferation of human cholangiocarcinoma cells. Methods: The effect of VEGF-C on FRH0201 was assayed by MTT. The cycle pattern and apoptosis was assayed using flow cytometry. The effect of VEGF-C on homotypic adhesion and metastasis in FRH0201 was examined with 3H-TdR infiltration and Boyden chamber. Results: VEGF-C could enhance the proliferation of FRH0201 in a dose and time dependent manner. And VEGF-C could inhibit cell apoptosis significantly. After cultured for 2 hours with 1, 5, 10ng/ml of VEGF-C, there were more cells in the lower chamber than the control group. After 60, 90, 120 minutes induction by 1ng/ml、5ng/ml、10ng/ml, the cells showed significantly lower homotypic adhesion than that of the control group. Conclusions: VEGF-C could enhance the proliferation of FRH0201 and inhibit cell apoptosis. VEGF-C could decrease homotypic adhesion of FRH0201 and might be a cause of the metastasis.

Objective To study the effects of environmental noise on the health of frontage uptown residents in Fuzhou city. Methods The AWA6218B sound-level meter was used to determine the sound intensity in five frontage uptowns, the testing time was at noon and in the evening, 213 inhabitants were selected to investigated the health effects by the questionnaire. Results The five tested frontage uptowns' Leq were 57.4-67.7 dB(A), which was in the extent of loudness. Some residents considered the noise as the main pollution which impacted their living quality. The noise had the adverse effect on sleeping, emotion, audition, working and study. Conclusion Environmental noise has serious adverse effects on the health of the frontage uptown inhabitants.

Objective To determine the role of SCN1A gene variation in the development of familial febrile seizures (FS).Methods Clinical data were collected from 8 familial FS pedigrees, and peripheral venous blood samples were collected from the probands and other available family members. All 26 coding exons and exon-intron boundaries at least 50 bases of the human SCN1A gene were amplifled by polymerase chain reaction, the products were subsequently sequenced. To novo variation, other family members were screened for the corresponding exons. Two hundred age-matched healthy children were served as normal controls. ResultsA total of 33 variations in the SCN1A gene were identifled in these families. Of these variations, one was a missense mutation; the remaining 32 variations were previously submitted as single nucleotide polymorphisms (SNPs). A c.2650G>A heterozygous missense mutation in exon 15 of the SCN1A gene found in the proband of family 4 was inherited from his father who had seizures with fever in early childhood. The c.2650G>A mutation was absent in the 400 alleles of normal controls. To the best of our knowledge, the SCN1A c.2650G>A mutation has neither been reported in the NCBI SNP database nor in the literature to date. The c.2650G>A mutation changes a glycine at amino acid 884 in the SCN1A protein to a serine (p.Gly884Ser). Protein sequence analysis showed that the p.Gly884Ser is located at a highly conserved region between the 4th and 5th transmembrane segment of the homologous domain Ⅱ of voltage-gated sodium channel 1 subunit (DIIS4-S5). ConclusionsThe pathogenesis of familial febrile seizures was related to the SCN1A variation, the mutation outside the region of the voltage sensor (S4) and ion channel pore (S5-S6) of the voltage gated sodium channelα-subunit may be an important factor to cause mild phenotype epilepsy syndrome.

Oxidative stress has been implicated in brain injury after ischemia, which is a complex cascade. These oxidants produced by oxidative stress are directly involved in oxidative damage with cellular macromolecules such as lipids, proteins and nucleic acids, which lead to cell death. Oxidants are also mediators in signaling involving mitochondria pathway, DNA repair enzymes, and transcription factor that may lead to apoptosis after cerebral ischemia. Antioxidangt enzymes (such as superoxide dismutase,etc) provide useful tools in dissecting the events involving oxidative stress in signaling and damage in ischemic brain injury. This review focuses on the mechanisms of oxidative stress during brain ischemia.
