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 explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.
