Familial non-medullary thyroid carcinoma (FNMTC) is de fi ned as the presence of two or more affected fi rst-degree relatives with non-medullary thyroid cancers without other known familial syndromes. FNMTC is one of the most inheritable forms of all cancers, with a high risk of a first-degree relative developing the disease. Compared with sporadic non-medullary thyroid carcinoma (NMTC), FNMTC presents at a younger age and is associated with a higher incidence of multifocal disease and metastasis. This in-creased aggressiveness has been hypothesized to translate into higher recurrence rates and decreased survival of patients with FNMTC. The genes involved in the pathogenesis of FNMTC are yet to be elucidated, although some recent studies identified several predisposi-tion loci with a high degree of genetic heterogeneity. Since 2005, next-generation sequencing (NGS) technologies have been developing as rapid, high-throughput, and cost-effective approaches to fulfill medical sciences and research demands. With the use of NGS, the un-derlying causative genes can be directly distinguished via systematic filtering, through which the identified gene variants are verified for novelty and functionality.

Objective To investigate the protective effects of hyperbaric oxygen(HBO)against brain dam- age from hypoxic ischemia(HIBD)in neonatal rats.Methods One hundred and seventeen 7-day-old Sprague- Dawley rats were randomly divided into 4 groups:a control group(n=32),a hypoxic ischemia brain damage group (HIBD group,n=30),a hyperbaric air group(HBA group,n=27),and a hyperbaric oxygen group(HBO group, n=28).The HIBD model was established by permanent occlusion of the left common carotid artery followed by expo- sure to a mixture of 8% oxygen/92% nitrogen for 2 h(at 37℃).HBO therapy was administered to the HBO group after the hypoxia exposure once a day for 7 d,as was HBA therapy to the HBA group.Apoptotic cells in the cortex and hippocampus(A_(CH)cells)were measured using TUNEL at 9 d after birth,and the ratios of left and right cerebral hemisphere weight(R_(L/R))and rate of weight gain(GRW)were recorded 14 d after birth.A radial arm maze acquisi- tion test(RAMAT)was administered at 30 to 35 days.Lastly,the neuron density in the CA_1 subfield of the rats' hip- pocampi(ND_(CAI)was measured with Nissl staining.Results R_(L/R)and GRW in the HIBD group were significantly lower than in the control group(P<0.01),while R_(L/R)was increased in the HBO and HBA groups,especially in the HBO group(P<0.01),although there was no significant difference in GRW between the groups.Compared with the control group,A_(CH)cells were increased and ND_(CAI)was decreased in the HIBD group(P<0.01),while A_(CH)cells were decreased and ND_(CAI)was elevated in the HBO group in comparison with the HIBD group(P<0.01).There was no change in A_(CH)cells or ND_(CAI)in the HBA group.The RAMAT results for the HIBD group,including the time to find the arms baited with water,average times of working errors and reference memory errors,were significantly high- er than those of the control group,while these values for the HBO group were obviously lower than for the HIBD group,and there was no change for the HBA group(P>0.05).Conclusion HBO therapy might increase the re- covery of learning and memory function by attenuating HIBD in neonatal rats.

Objective To investigate the chemical constituents and activities of Linum usitatissimum L.aboveground. Meth-ods The chemical constituents were separated through silica gel,ODS,Sephadex LH-20,and semi-preparative RP-HPLC chroma-tography and identified by optical rotation and spectroscopic analysis. All of the isolates were evaluated for their inhibitory activities by the luciferase assay. Results Eight dibenzylbutyrolactone lignans were separated from L. usitatissimum and identified as(-)-hinoki-nin(1),(-)-bursehernin(2),(-)-dimethylmatairesinol(3),(-)-yatein(4),(-)-thujaplicatin trimethyl ether(5),nemerosin (6),(+)-E-7,8-dehydromatairesinol dimethyl ether(7),and E-7,8-dehydrothujaplicatin trimethyl ether(8),respectively. Conclu-sion Compounds 7 and 8 were isolated from L. usitatissimum for the first time,and NMR spectral data of compound 8 were reported for the first time. Compounds 1 and 3 showed moderate inhibitory activities on IL-6/STAT3 signaling pathway with IC50 values of 42.12 and 43.43μmol/L,respectively.

Objective:To test the validity and reliability of Chinese version of Psycho-Educational Profile (C-PEP) for children with autism in order to develop an assessment tool suitable for Chinese autistic children.Methods:A sample of 438 children who were diagnosed as autism according to the Diagnostic and Statisti-cal Manual of Mental Disorders,Fourth Edition (DSM-IV)criteria and aged from 2 to 11 coming from four differ-ent medical or educational rehabilitation agencies of Beijing,Wuhan,Shenzhen and Changchun were selected.488 Children with 2 to 7 years old were sampled from ordinary kindergartens.This study examined the validity and reli-ability of C-PEP using autism sample.Construct validity was tested with the C-PEP by inter-subscale Pearson corre-lations and confirmative factor analysis.Criterion-related validity was tested with the Peabody Picture and Vocabula-ry Test (PPVT),Combined Raven Test (CRT),Adaptive Behavior Scale (ABS),Childhood Autism Rating Scale (CARS)and the age as criteria.Discriminate validity was obtained by comparing the differences between the typi-cal and autism samples with the total scores of C-PEP.Internal consistency and rater reliability of C-PEP were ex-amined by Cronbach α,ANOVA of rater variation and intra-class correlation coefficients.Results:The inter-sub-scale correlations of C-PEP were medium relevance,the subscale and domain correlations were relatively high.Confirmative factor analysis indicated a relatively high fitting index between the model and sample da-ta.Regarding the concurrent validity of the C-PEP,the development total score was significantly correlated with the Raven's IQ,PPVT IQ,and ADQ scores,pathological behavior total score was positively related to the CARS score.T test results showed that children with autism were significantly behind the typical children at all age lev-els.Results also revealed that the internal consistency based on coefficient alpha and the intra-class correlation coef-ficients of raters for all subtests of C-PEP were reliable.Conclusion:It suggests that the Chinese version of Psycho-Educational Profile (C-PEP)is of good validity and reliability,and it could be used as an effective tool for measur-ing children with autism.

Objective To explore the impact of self-care efficacy and psychological resilience on post-traumatic stress disorders (PTSD) in breast cancer patients.Methods 303 patients with breast cancer were investigated with PTSD Checklist-Civilian Version(PCL-C),Chinese version of strategies used by people to promote health (C-SUPPH) and Connor-Davidson Resilience Scale (CD-RISC).Results The total score of PCL-C was (38.02±8.35) and the incidence of PTSD in breast cancer inpatients was 20.13% with 61 cases.Correlation analysis showed that PTSD was negatively correlated with the score of self-care efficacy (r=-0.387) and psychological resilience (r=-0.341) (P< 0.01,P< 0.05).Multiple regression analysis showed that self-care efficacy (β=-0.274),psychological resilience (β=-0.149) and neoplasm staging(β=0.136) were influencing factors of PTSD.Conclusion Intervention measures should be taken according to self-care efficacy and psychological resilience of breast cancer patients so as to reduce the PTST incidence and improve mental health of patients.
