Objective:To analyze the effects of different courses of hyperbaric oxygen combined with sertraline on sleep disorders and serum neurologic injury factors in patients after cerebral hemorrhage.Methods:A total of 120 patients with sleep disorders after cerebral hemorrhage were divided into control group ( n=60) and observation group ( n=60) by random number table method. The control group was treated with sertraline only, while the observation group was treated with hyperbaric oxygen on the basis of the treatment in the control group. The sleep quality, clinical efficacy, the levels of serum neuron-specific enolase (NSE), intercellular adhesion molecule-1 (ICAM-1), and tumor necrosis factor-α (TNF-α) before and 10, 20, and 30 d after treatment were compared between the two groups. Results:The scores of Pittsburgh sleep quality index (PSQI) of the observation group were significantly lower than those of the control group at every time point of treatment ( P<0.05); the total sleep time, total deep sleep time, total light sleep time, and rapid eye movement (REM) sleep time of the observation group were significantly longer than those of the control group ( P<0.05); and the sleep latency of the observation group was significantly shorter than that of the control group ( P<0.05). With the prolongation of the treatment course, the PSQI scores of both groups showed decreasing trends ( P<0.05); the total sleep time, total deep sleep time, total light sleep time, and REM sleep time of both groups tended to prolong ( P<0.05); and the sleep latency tended to be shorter ( P<0.05). The total effective rate of the observation group was significantly higher than that of the control group at 10, 20, and 30 d after treatment ( P<0.05). With the prolongation of the treatment course, the total effective rates of the two groups showed increasing trends ( P<0.05); the levels of serum NSE, ICAM-1, and TNF-α in the observation group were significantly lower than those in the control group at every time point of treatment ( P<0.05); and with the prolongation of the treatment course, the above indicators of the two groups showed decreasing trends ( P<0.05). Conclusion:Hyperbaric oxygen therapy combined with sertraline can improve the sleep quality and clinical efficacy of patients after cerebral hemorrhage with sleep disorders.

PURPOSE: The importance of long noncoding RNAs (lncRNAs) in tumorigenesis has recently been demonstrated. However, the role of lncRNAs in development of thyroid cancer remains largely unknown. MATERIALS AND METHODS: Using quantitative reverse transcription polymerase chain reaction, expression of three lncRNAs, including BRAF-activated long noncoding RNA (BANCR), papillary thyroid cancer susceptibility candidate 3 (PTCSC3), and noncoding RNA associated with mitogen-activated protein kinase pathway and growth arrest (NAMA), was investigated in the current study. RESULTS: Of the three lncRNAs (BANCR, PTCSC3, and NAMA), expression of BANCR was significantly up-regulated while PTCSC3 and NAMA were significantly down-regulated in papillary thyroid carcinoma (PTC) compared to that in normal tissue. BANCR-knockdown in a PTC-derived cell line (IHH-4) resulted in significant suppression of thyroid stimulating hormone receptor (TSHR). BANCR-knockdown also led to inhibition of cell growth and cell cycle arrest at G0/G1 phase through down-regulation of cyclin D1. In addition, BANCR was enriched by polycomb enhancer of zeste homolog 2 (EZH2), and silencing BANCR led to decreased chromatin recruitment of EZH2, which resulted significantly reduced expression of TSHR. CONCLUSION: These findings indicate that BANCR may contribute to the tumorigenesis of PTC through regulation of cyclin D1 and TSHR.

Objective To investigate the relationship among the late-life depression ( LLD ) , cognitive function and white matter lesions ( WML) , after excluding vascular risk factors and brain atrophy.Methods The depression and cognition status of 277 patients were assessed using a variety of neurological scales, and the actually enrolled patients were divided into LLD group ( 77 cases ) and the non-depressed group (103 cases).The independent samples t test and multivariate Logistic regression were used to analyze independent risk factors for depressive symptoms with the model Ⅰ of controlling age , sex, years of education and the model Ⅱof controlling age, sex, years of education, high blood pressure, diabetes and coronary heart disease.Under the premise of controlling mode Ⅱand brain atrophy , partial correlation was used to analyze the correlations of depressive symptoms and cognitive function and WML , and the correlation between depressive symptoms and cognitive items.Results The results showed that the proportion of high blood pressure (90.9%vs 74.7%, χ2 =6.342,P=0.046), cognitive scores (19.23 ±7.05 vs 22.99 ± 6.71, t=3.343,P=0.001), WML level 2 proportion (65.1% vs 34.9%, χ2 =7.373,P=0.025) and temporal lobe atrophy of hippocampal sulcus ratio (0.24 ±0.03 vs 0.22 ±0.03, t=-2.041,P=0.044) had statistically significant difference between the two groups.Multivariate Logistic regression showed that cognitive function was an independent risk factor for depression ( OR=1.63,95% CI 1.01 -2.80, P=0.030).Controlling for all risk factors , partial correlation analysis showed that depressive symptoms were correlated with cognitive function ( r=-0.239,P=0.004) and WML ( r=0.222,P=0.008) and the atrophy of temporal lobe and hippocampus ( r=0.173, P=0.040 ).Under the model Ⅱ, depressive symptoms correlated with attention (r=-0.175, P=0.040), memories (r=-0.140, P=0.050) and drawing clock test ( r=-0.186, P=0.029 ).Conclusions Excluding vascular risk factorts , brain atrophy and WML , cognitive impairment has significant correlation with depressive symptoms.Vascular risk factors are involved in the occurrence of depression , and WML may be the severity of cognitive impairment reserve marker.LLD patients showed hippocampal atrophy similar with early AD , manifesting the cognitive feature of memory and executive dysfunction and attention disorder .
