Objective To analyse the differential expression of miRNAs in the brain of offsprings of hypothyroid and normal rats,and to explore the molecular mechanism underlying the effect of hypothyroidism on brain development in the offspring.Methods Forty-eight female Wistar rats were assigned to (1) control group (n =24),and (2) hypothyroid group after complete thyroidectomy (n =24).Serum TSH and Total thyroxine (T4) were measured one month after the surgery.Brain samples of fetal or postnatal rats were obtained during four different developmental stages:embryonic days (E) 13,E17,postnatal days (P) 0 and P7.The hippocampus and cortex were separated on P7.MiRNAs were isolated from tissues and two samples were used at each time point studied to reduce the influence of individual differences.The brain samples were detected by Gene Chip miRNA arrays (Affymetrix).Results In the brain tissues of fetal or neonatal rats of maternal hypothyroid rats,two miRNAs (mir-206,-324-5p) on E13,three miRNAs (mir-34c,-204,-194) in cortex on P7,and five miRNAs (mir-146b,-532-5p,-384-5p,-215,-212) in hippocampus on P7 were up-regulated by over 2 folds.Five miRNAs (mir-200b,-200c,-217,-672,-139-5p) on E17,one miRNA (mir-376-3p) on P0,and four miRNA (mir-672,-204,-335,-376-3p) in hippocampus on P7 were decreased by 50％ or more.Conclusion The miRNA expression profiles in the rat brain of offspring with maternal hypothyroidism are characterized by miRNA arrays.The identification of a subset of brain expressed miRNAs in the brain may explain the brain development abnormalities resulting from maternal hypothyroidism.

Objective To investigate the association of single nucleotide polymorphisms(SNP)in p21and p27 genes with the risk of epithelial ovarian cancer(EOC).Methods Genotypes were analyzed by polymerase chain reaction-restrictive fragment length polymorphism(PCR-RFLP)method in 234 patients with EOC and 284 control women in China.Results (1)The frequencies of the p21 in healthy controls were 34.2%.49.6%and 16.2%,while the distribution of the C and T allele was 59.0%and 41.0%,respectively.The p21 C/C(28.2%),C/T(53.0%),T/T(18.8%)distribution in ovarian cancer patients was not significantly different from that in healthy controls(P＞0.05).There was no statistic difference in allele distribution between ovarian cancer patients and healthy controls(P＞0.05)either.The stratification analysis by tumor histological type did show that the genotype distribution in four types of ovarian cancer patients was significantly different from that in healthy controls(P=0.02).The C/C genotype was likely to reduce the risk of epithelial endometrial cancer.and the adjusted odds ratio was 0.56(95%CI:0.32-0.98).(2)The genotype frequencies of the p27 in healthy controls were 88.4%,10.9%and 0.7%.while the distribution of the V and G allele was 93.8%and 6.2%.respectively.The V/V(93.6%),V/G(5.1%)and G/G(1.3%)distribution in ovarian cancer patients was significantly different from that in healthy controls(P=0.04).There was no statistic difference in allele distributionbetween ovarian cancer patients and healthy controls(P＞0.05).Compared with the V/G and G/G genotypes,the V/V genotype increased the risk of EOC,the adjusted odds ratio was 1.92(95%CI:1.02-3.63).Conclusion The C/C genotype of p21 may reduce the risk of epithelial endometrial cancer,and the genotype of p27 V/V may be a potential risk factor for susceptibility to EOC.

Objective:To find a short, neutralizing antibody-inducible, ORF2-encoded protein by means of comparing the immunogenicity of pN472-C617 and pN477-C613 which represent amino acids 472-617 and 477-613 of HEV ORF2-encoded protein of hepatitis E virus(HEV) genotype 4, respectively.Methods:The two recombinant proteins were expressed, purified, and then used to immunize BALB/c mice. Anti-HEV titers in the immune sera were detected by ELISA. Anti-HEV neutralizing activity was tested by a PCR-based in vitro neutralization assay.Results:Both of the two recombinant proteins were efficiently expressed in E.coli in soluble forms. The purified proteins induced mice to develop high levels of anti-HEV specific antibodies. However, only the immune sera obtained from the mice immunized with pN472-C617 showed the neutralizing activity to the homologous HEV strain by preventing the virus from absorption on PLC/PRF/5 cells surfaces and replication in the cells. The immune sera against pN477-C613, which was truncated five amino acids from both N- and C-terminal of pN472-C617, had no HEV neutralizing activity.Conclusion:The pN472-C617 is the shortest neutralizing antibody-inducible ORF2-encoded protein of HEV reported in literatures so far. It may be considered as a potential candidate for a novel HEV subunit vaccine in our future study.

Objective: To evaluate the clinical profile of target controlled infusion based anesthesia using remifentanil and propofol. Methods: 16 ASA I II patients undergoing elective laparoscopic cholecystectomy were enrolled. Remifentanil was set at 7?g?L -1 as target and propofol at 3 mg?L -1 throughout the whole procedure. The hemodynamics during induction of anesthesia and recovery profiles were recorded. Arterial blood samples for analysis of remifentanil were taken 15min after infusion, 20 min after infusion and at time of emergence. Results: After induction of anesthesia, systolic blood pressure (SBP) decreased from (144?27) mm Hg to (101?18) mm Hg ( P 0.05). SBP, MBP and HR remained stable after intubation for 3min. No patient showed haemodynamic stress to tracheal intubation. Times from stopping administration of anesthetics until full spontaneous respiration, eye opening, tracheal extubation, orientation and discharging from the postanesthetic care unit (PACU) were (12?6), (9?4), (13?6), (15?5) and (19?7) min respectively. Measured drug values of remifentanil were (4.6?9.5) ?g?L -1 , (6.6?11.5) ?g?L -1 , (1.2?8.7) ?g?L -1 respectively. Conclusion: Remifentanil/propofol TCI based anesthesia achieved the optimal hemodynamic stability during anesthesia induction and maintenance, and better recovery profile from anesthesia. Measured drug values of remifentanil showed a considerable interindividual variation and more lower than the set target.

Objective To investigate the characteristics of family environment in children with attention deficit hyperactivity disorder (ADHD) in clinics, and analyse the risk factors for ADHD. Methods Two thousand two hundred and ninety-six children with inattention, hyperactivity or unfavourable school performance were subjected to diagnosis with DSM-Ⅳ criteria in clinics. The characteristics of family environment were investigated by self-prepared questionnaires. The risk factors for ADHD were explored by univariate analysis and noneonditioned multivariate Logistic regression analysis. Results Seven hundred and twenty children were diagnosed with ADHD. There were significant differences in family environment between children with ADHD and those without(P<0.05 or P<0.01). The risk factors for ADHD included discord between parents, parental smoking and maternal depression during pregnancy and after delivery, while older age, female, paternal higher educational background were protective factors for ADHD. Conclusion Unfavourable family environment may be associated with the prevalence of ADHD, and special attention should be paid to the family environment in the treatment of ADHD.

Objective To explore the improvement of core symptoms and detailed function in children with attention deficit hyperactivity disorder (ADHD) after treatment with methylphenidate extended-release tablets, and analyse the relationship between core symptoms reduction and detailed function improvement. Methods One hundred and fifty-six children with confirmed ADHD were rated with Swanson, Nolan, and Pelham, Version Ⅳ (SNAP-Ⅳ)Scale before treatment, then methylphenidate extended-release tablets were orally administered 18 mg once daily for 1 month, and children were rated again by means of SNAP-Ⅳ Scale and detailed function improvement questionnaire. The core symptoms reduction and detailed function improvement were observed, and their relationship was analysed. Results The primary mean scores of each factor in SNAP-Ⅳ Scale decreased significantly after treatment with methylphenidate extended-release tablets(P< 0.001). The reduction rate of factor IOWA/I/O was the most significant (>50%), followed by ADHD-H/Im and ADHD-In. The performance of school study, homework doing and social behavioral function was improved, and the detailed function was significantly improved. The reduction rate in ADHD-In factor was significantly correlated with improvement of school study and homework doing (P<0.01). The reduction rate in ADHD-H/Im factor was significantly correlated with improvement of social behavioral function(P<0.05). Conclusion Methylphenidate extended-release tablets play a role in both core symptoms reduction and detailed function improvement in children with ADHD, and core symptoms reduction is related to detailed function improvement to some degree. Methylphenidate extended-release tablets exert different effects on different detailed function.
